During operation of the portable air conditioner, the condensate water is easily generated at the evaporator and needs to be removed timely to prevent the components in the portable air conditioner from being damaged and the heat exchange efficiency of the portable air conditioner from being affected. Generally, a rotary wheel (for example, a water-pumping wheel) is arranged in the portable air conditioner. The condensate water is atomized and thrown to the condenser by means of high-speed rotation of the rotary wheel, so that the condensate water may absorb the heat of the condenser to evaporate.

However, the above rotary wheel is simple in structure, and the position and watering direction of the rotary wheel are fixed. Most thrown condensate water moves in an up-down direction and cannot contact with the condenser to evaporate. Moreover, the above rotary wheel is relatively low in atomization efficiency. When the portable air conditioner works in a high-humidity environment (for example, the relative environmental humidity is greater than 90%). the generation rate of the condensate water is greater than the evaporation rate of the condensate water. The portable air conditioner is prone to shutdown due to the fullness of the condensate water, and it needs to discharge water manually.

In some solutions, the size, quantity, and angle of blades of the rotary wheel may be adjusted to improve the atomization efficiency, so as to further improve the evaporation rate of the condensate water. In the above solution, the rotary wheel atomizes the condensate water by means of a centrifugal force mainly by adjusting the rotating speed. Therefore, the atomization efficiency of the rotary wheel on the condensate water is limited by the rotating speed of the electric machine, so that the atomization efficiency of the condensate water is low.

In order to solve the above problem, some embodiments of the present disclosure provide a portable air conditioner 1. By arranging a plurality of atomization holes, the portable air conditioner 1 further enables the condensate water to be crushed into droplets by means of the fine atomization holes while atomizing the condensate water by means of the centrifugal force, so as to improve the atomization efficiency of the condensate water.

The portable air conditioner 1 is an air conditioner with integrated indoor unit and outdoor unit, and is movable. By arranging the components such as the compressor, the condenser, and the evaporator in a box body, the portable air conditioner 1 achieves refrigerating and heating effects.

In some embodiments, as shown in FIG. 1, the portable air conditioner 1 includes an outdoor portion 10.

The outdoor portion 10 includes a first housing 100. The first housing 100 is internally provided with a first channel (an outdoor air channel) for the circulation of outdoor air. As shown in FIG. 2, the first housing 100 includes a first base 1001. Components (for example, a compressor, a first heat exchanger 101, and a first fan) in the outdoor portion 10 are arranged on the first base 1001, respectively. Here, the compressor, the first heat exchanger 101, and the first fan will be described hereinafter.

The outdoor portion 10 further includes a first air inlet (an outdoor air inlet). The first air inlet is arranged on the first housing and communicates an interior of the first housing 100 and an outdoor environment.

The outdoor portion 10 further includes a first air outlet (an outdoor air outlet). The first air outlet is arranged on the first housing 100 and is located on a side of the first housing 100 facing the outdoor environment. Thus, the outdoor air may enter the first housing 100 from the first air inlet and flow back to the outdoor environment from the first air outlet after heat exchange.

In some embodiments, the outdoor portion 10 further includes a compressor. The compressor is arranged in the first housing 100 and is configured to compress a refrigerant to enable the low-pressure refrigerant to be compressed to form a high-pressure refrigerant. The compressor includes an exhaust port and an air return port. The low-pressure refrigerant enters the compressor from the air return port, and the compressor compresses the low-pressure refrigerant into the high-pressure refrigerant which is exhausted from the exhaust port. The high-pressure refrigerant releases heat at the condenser. Then, the refrigerant absorbs heat at the evaporator after pressure reduction. Finally, the refrigerant enters the compressor from the air return port.

In some embodiments, as shown in FIG. 2, the outdoor portion 10 further includes a first heat exchanger 101 (an outdoor heat exchanger). The first heat exchanger 101 is arranged in the first housing 100 and is located in the first channel. The first heat exchanger 101 is configured to perform heat exchange on the outdoor air and the refrigerant transmitted in the first heat exchanger 101. For example, the first heat exchanger 101 works as the condenser in a refrigeration mode of the portable air conditioner 1, and the exhaust port of the compressor is in communication with the first heat exchanger 101; and the first heat exchanger 101 works as the evaporator in a heating mode of the portable air conditioner 1, and the air return port of the compressor is in communication with the first heat exchanger 101.

In some embodiments, as shown in FIG. 3, the first heat exchanger 101 may include a plurality of sub-heat exchangers 1011. For example, the plurality of sub-heat exchangers 1011 include first sub-heat exchangers 121 and second sub-heat exchangers 122. The first sub-heat exchangers 121 and the second sub-heat exchangers 122 are spaced apart from each other in a third direction. Here, the third direction may be an air inlet direction of the outdoor portion 10 or a thickness direction (for example, a front-back direction) of the portable air conditioner 1.

In some embodiments, as shown in FIG. 9A and FIG. 9B, the first heat exchanger 101 includes a plurality of refrigerant pipes 123. The plurality of refrigerant pipes 123 are connected to the compressor and the refrigerant from the compressor passes through the refrigerant pipes 123 for heat exchange.

Each of the first heat exchangers 101 further includes a plurality of fins 124, and the plurality of refrigerant pipes 123 interpenetrate the plurality of fins 124 and are spaced apart from each other in a length direction (for example, a third direction) of the plurality of fins 124.

In some embodiments, the outdoor portion 10 further includes a first fan (an outdoor fan). The first fan is arranged in the first housing 100 and is configured to suck the outdoor air into the outdoor portion 10 through the first air inlet and delivers the outdoor air exchanging heat with the first heat exchanger 101 via the first air outlet.

In some embodiments, as shown in FIG. 4A and FIG. 4B, the outdoor portion 10 further includes a water-collecting member 103. The water-collecting member 103 is located at a bottom of the first housing 100. For example, the water-collecting member 103 is a groove and is arranged at the lowest position of the first base 1001 to accommodate the condensate water in the portable air conditioner 1. The first heat exchanger 101 is arranged in the water-collecting member 103.

When the first heat exchanger 101 serves as the evaporator, condensate water is easily generated at a surface of the first heat exchanger 101. The condensate water on the surface of the first heat exchanger 101 may be converged into the water-collecting member 103, and after the water-collecting member 103 is filled with the condensate water, the condensate water may be discharged through a drainage pipeline, so that the condensate water in the portable air conditioner I may be prevented from flowing to other components to damage the components.

It should be noted that in a case where the first heat exchanger 101 includes a plurality of sub-heat exchangers 1011, the plurality of sub-heat exchangers 1011 are arranged in the water-collecting member 103, so that the water-collecting member 103 collects the condensate water flowing down from the surfaces of the plurality of sub-heat exchangers 1011.

In some embodiments, as shown in FIG. 1, the portable air conditioner 1 includes an indoor portion 20. The indoor portion 20 and the outdoor portion 10 are stacked, and the indoor portion 20 is located on a side (for example, an upper side) of the outdoor portion 10 in a second direction. Here, the second direction may be a height direction (for example, an up-down direction) of the portable air conditioner 1, and is perpendicular to the third direction.

The indoor portion 20 includes a second housing 200. The second housing 200 is internally provided with a second channel (an indoor air channel) for the circulation of indoor air. The second housing 200 is connected to the first housing 100 and is located on a side (for example, an upper side) in a height direction of the first housing 100.

As shown in FIG. 3, the second housing 200 includes a second base 2001. Components (for example, a second heat exchanger 201) in the indoor portion 20 may be arranged on the second base 2001, and the second base 2001 is located above the first base 1001. Here, the second heat exchanger 201 will be described hereinafter.

The second housing 200 further includes a drain hole 2002 (as shown in FIG. 10A). The drain hole 2002 (a water spray hole) is arranged at the lowest position of the second base 2001 and in communication with an internal space of the outdoor portion 10. Thus, the condensate water generated on the surface of the second heat exchanger 201 may be converged on the second base 2001 and then flow into the outdoor portion 10 via the drain hole 2002. The condensate water flowing into the outdoor portion 10 subjected to the action of gravity may be converged into the water-collecting member 103.

In some embodiments, the first housing 100 and the second housing 200 may be an integrated member to improve the structural strength and the assembly efficiency of the portable air conditioner 1.

As shown in FIG. 1, the indoor portion 20 further includes a second air inlet 202 (an indoor air inlet). The second air inlet is arranged on the second housing 200 and communicates an interior of the second housing 200 and an indoor environment.

The indoor portion 20 further includes a second air outlet (an indoor air outlet). The second air outlet is arranged on the second housing 200 and is located on a side of the second housing 200 facing the indoor environment. Thus, the indoor air may enter the second housing 200 from the second air inlet and flow back to the indoor environment from the second air outlet after heat exchange.

In some embodiments, as shown in FIG. 3, the indoor portion 20 further includes a second heat exchanger 201 (an indoor heat exchanger). The second heat exchanger 201 is arranged in the second housing 200 and is located in the second channel. The second heat exchanger 201 is configured to perform heat exchange on the indoor air and the refrigerant transmitted in the second heat exchanger 201. For example, the second heat exchanger 201 works as the evaporator in the refrigeration mode of the portable air conditioner 1, and works as the condenser in the heating mode of the portable air conditioner 1.

In some embodiments, the indoor portion 20 further includes a second air duct member (an indoor air duct member), and the second air duct member is arranged in the second housing 200. The second air duct member is configured to guide the influent indoor air.

In some embodiments, the indoor portion 20 further includes a second fan (an indoor fan). The second fan is arranged in the second air duct member and configured to suck the indoor air into the indoor portion 20 through the second air inlet and delivers the indoor air exchanging heat with the second heat exchanger 201 via the second air outlet. For example. the second fan and the second fan are cross flow fans. The cross flow fans may suck or discharge air in axial directions of the fans and increase the air quantity and the air pressure of air flows. It should be noted that the supply air rates of the portable air conditioner I may be adjusted by controlling the rotating speed of the second fan.

In some embodiments, the portable air conditioner 1 further includes a pressure reducer connected between the first heat exchanger 101 and the second heat exchanger 201. The pressure reducer is configured to adjust a refrigerant pressure flowing through the first heat exchanger 101 and the second heat exchanger 201, so as to adjust a refrigerant flow circulating between the first heat exchanger 101 and the second heat exchanger 201. The compressor, the first heat exchanger 101, the pressure reducer, and the second heat exchanger 201 are connected in sequence to form a refrigerant loop.

The water-lifting assembly 30 (a water-pumping assembly) in some embodiments of the present disclosure will be introduced below.

In some embodiments, as shown in FIG. 4A and FIG. 4B, the portable air conditioner 1 further includes a water-lifting assembly 30. The water-lifting assembly 30 is arranged in the outdoor portion 10 and is configured to atomize and throw the condensate water in the water-collecting member 103 to the first heat exchanger 101. Thus, the water-lifting assembly 30 may throw the atomized condensate water to the high-temperature fins of the condenser, so that the condensate water absorbs heat to evaporate, which avoids shutdown of the portable air conditioner I due to fullness of the condensate water, thereby reducing the number of times of manually discharging water.

In some embodiments, the portable air conditioner 1 may include one or more water-lifting assemblies 30 to improve the atomization and evaporation efficiencies of the condensate water.

In some embodiments, as shown in FIG. 4A and FIG. 4B, the water-lifting assembly 30 includes a first driving member 31. The first driving member 31 is arranged at a bottom of the outdoor portion 10. For example, the portable air conditioner 1 further includes a mounting portion 40 (a mounting base), and the mounting portion 40 is arranged on the first base 1001. The first driving member 31 is arranged on the mounting portion 40. The first driving member 31 may be an electric machine.

The water-lifting assembly 30 further includes a first rotary shaft 32. The first rotary shaft 32 is in transmission connection with the first driving member 31. For example, a first end of the first rotary shaft 32 is in transmission connection with the first driving member 31. Here, “transmission connection” may mean that a movement of one of the two connected component may be transferred to the other one, and the connecting mode between the two components includes, but is not limited to, at least one of rotary connection, sliding connection, gear engaging transmission connection, chain wheel transmission connection, cam mechanism transmission connection, and the like.

The first driving member 31 and the first rotary shaft 32 may be arranged outside the water-collecting member 103, respectively. For example, the first driving member 31 is away from the water-collecting member 103, so that the first driving member 31 is prevented from being damaged by water, and the service life of the first driving member 31 is prevented from being shortened due to a humid ambient environment.

The water-lifting assembly 30 further includes a rotary wheel 33. The rotary wheel 33 is in transmission connection with the first rotary shaft 32, and at least part of the rotary wheel 33 is located in the water-collecting member 103. The rotary wheel 33 is configured to, driven 30) by the first driving member 31, rotate, so as to atomize and throw the condensate water in the water-collecting member 103 to the first heat exchanger 101.

In some embodiments, as shown in FIG. 4A and FIG. 4B, in a case where the first heat exchanger 101 includes a plurality of sub-heat exchangers 1011, the rotary wheel 33 of the water-lifting assembly 30 may be located between two adjacent sub-heat exchangers 1011.

For example, when the first heat exchanger 101 includes two sub-heat exchangers 1011, and the two sub-heat exchangers 1011 are arranged in one water-collecting member 103. the water-lifting assembly 30 includes one rotary wheel 33, and the rotary wheel 33 is located between the two sub-heat exchangers 1011. Thus, water mist formed by atomizing the condensate water by the water-lifting assembly 30 may be attached to surfaces of the two sub-heat exchangers 1011, so that the contact area between the first heat exchanger 101 and the atomized condensate water may be increased, and the atomization efficiency and the evaporation efficiency of the condensate water are improved.

When the first heat exchanger 101 includes three sub-heat exchangers 1011, the water-lifting assembly 30 includes two rotary wheels 33, and the two rotary wheels 33 are located between the two sub-heat exchangers 1011. Thus, the condensate water may be uniformly thrown to the plurality of sub-heat exchangers 1011, and moreover, the atomization efficiency and the evaporation efficiency of the condensate water may further be improved.

It should be noted that the quantity of the rotary wheels 33 corresponds to the quantity of the water-collecting members 103. For example, in a case where the portable air conditioner 1 includes a plurality of water-collecting members 103, the portable air conditioner 1 may include a plurality of water-lifting assemblies 30. A plurality of rotary wheels 33 of the plurality of water-lifting assemblies 30 are located in the plurality of water-collecting members 103. respectively. Thus, the working stability of the water-lifting assemblies 30 may be improved. In a case where one water-lifting assembly 30 is damaged, other water-lifting assemblies 30 may still work.

It may be understood that in a case where the portable air conditioner 1 includes a plurality of water-lifting assemblies 30, the plurality of water-lifting assemblies 30 may share one first driving member 31 and one first rotary shaft 32. The plurality of rotary wheels 33 of the plurality of water-lifting assemblies 30 may be in transmission connection with the same first rotary shaft 32. Thus, the quantity of the first driving members 31 and the first rotary shaft 32 may be decreased, so that the cost is lowered, and the space occupied by the plurality of water-lifting assemblies 30 is reduced.

In some embodiments, as shown in FIG. 5A to FIG. 5C, the rotary wheel 33 includes a reinforcement member 331 (a reinforcement ring). The reinforcement member 331 is in transmission connection with the first rotary shaft 32, and is located in the water-collecting member 103. For example, a second end of the first rotary shaft 32 is in transmission connection with the reinforcement member 331, so that the first driving member 31 may drive the first rotary shaft 32 to rotate to enable the first rotary shaft 32 to drive the reinforcement member 331 to rotate.

In some embodiments, as shown in FIG. 5A to FIG. 5C, the reinforcement member 331 includes a first main body 3311. The first main body 3311 is annular and is configured to improve the structural strength of the water-lifting assembly 30.

The reinforcement member 331 further includes a plurality water intake holes 3312. The plurality of water intake holes 3312 are arranged in the first main body 3311, and are spaced apart from each other in a circumferential direction of the first main body 3311. Two or more water intake holes 3312 in the plurality of water intake holes 3312 may be spaced apart from each other in an axial direction of the first main body 3311.

Thus, when rotating, the reinforcement member 331 may drive the condensate water in the water-collecting member 103 to flow. Moreover, when the water intake holes 3312 are immersed below a water surface, the condensate water may flow into an inner side of the reinforcement member 331 (an inner side of the annular first main body 3311) from the water intake holes 3312.

In some embodiments, the water intake holes 3312 may be rectangular. The water intake holes 3312 extend in a peripheral direction of the first main body 3311. Thus, the extension direction of the water intake holes 3312 may be the same as the rotating direction of the first main body 3311, so that the water intake of the water intake holes 3312 may be improved when the reinforcement member 331 rotates.

It should be noted that the shape of the water intake holes 3312 may also be designed according to different processing equipment. In addition, the position, arrangement, and shape of the water intake holes 3312 may be designed according to the demand for the water intake.

In some embodiments, as shown in FIG. 5B and FIG. 5C, the reinforcement member 331 further includes a plurality of water locking members 3313. The plurality of water locking members 3313 are arranged on a side (for example, an inner side) of the first main body 3311 close to the plurality of first atomization members 332, and the plurality of water locking members 3313 are arranged corresponding to the plurality of water intake holes 3312. For example, two ends of any one water locking member 3313 in the plurality of water locking members 3313 are connected to two sides of the corresponding water intake hole 3312 in the peripheral direction of the first main body 3311, respectively. A gap is arranged between the water locking member 3313 and the corresponding water intake hole 3312. Here, the plurality of first atomization members 332 will be described hereinafter.

For example, the reinforcement member 331 further includes a plurality of water outlets 3314. The plurality of water outlets 3314 are arranged at two ends of the water locking member 3313, respectively, and communicates the intake hole 3312 with a gap 333 between the reinforcement member 331 and the plurality of first atomization members 332 (as shown in FIG. 6A), so that the condensate water flowing from the water intake hole 3312 may flow into the gap 333 between the plurality of first atomization members 332 and the reinforcement member 331 from the water outlets 3314.

In a case where the condensate water flows into the gap 333 between the plurality of first atomization members 332 and the reinforcement member 331 from the water intake holes 3312, after the gap 333 is filled with the condensate water, the water locking member 3313 deforms under a pressure of the condensate water to close the water intake holes 3312, so that the condensate water may be prevented from flowing out from the gap 333, thereby improving the atomization efficiency of the water-lifting assembly 30 on the condensate water.

In some embodiments, as shown in FIG. 6A and FIG. 6B, the rotary wheel 33 further includes a connecting member 334. The connecting member 334 is arranged in the reinforcement member 331 and is connected to the first rotary shaft 32. For example, the connecting member 334 is disc-shaped and is located at a middle position of the reinforcement member 331 in the axial direction. The first rotary shaft 32 is arranged on the connecting member 334 in a penetrating manner.

In some embodiments, as shown in FIG. 6A and FIG. 6B, the rotary wheel 33 further includes a plurality of first atomization members 332. The plurality of first atomization members 332 are arranged in the reinforcement member 331 and connected to the connecting member 334, respectively, so that the plurality of first atomization members 332 may rotate along with the rotation of the reinforcement member 331. The first atomization member 332 protrudes out of the reinforcement member 331 in the axial direction of the reinforcement member 331, so that the atomized condensate water may be thrown away from an edge of the first atomization member 332. Here, a surface of the first atomization member 332 may be called as an atomizing surface.

For example, the plurality of first atomization members 332 are arranged on two sides (for example, left and right sides) in the axial direction of the connecting member 334. respectively. The first rotary shaft 32 passes through the first parts of first atomization members 332, the connecting member 334, and the second parts of first atomization members 332 in sequence. It may be understood that the plurality of first atomization members 332 may be fixedly connected to the first rotary shaft 32, respectively, to improve the structural strength of the water-lifting assembly 30. Here, the first parts of first atomization members 332 are the first atomization members 332 located on one side (for example, the left side) in the axial direction of the connecting member 334, and the second parts of first atomization members 332 are the first atomization members 332 located on the other side (for example, the right side) in the axial direction of the connecting member 334.

In some embodiments, as shown in FIG. 6B to FIG. 6D, the first atomization member 332 includes a second main body 3321. An edge of the second main body 3321 is round. Thus. the atomized condensate water may be thrown away from any position of the round edge of the second main body 3321, so that the water-lifting assembly 30 throws the condensate water at multiple angles. Moreover, in the axial direction of the second main body 3321, the second main body 3321 protrudes out of the reinforcement member 331. Thus, the edge of the first atomization member 332 may be prevented from being shielded by the reinforcement member 331, so that the atomized condensate water may be thrown away from the edge of the first atomization member 332, thereby improving the atomization efficiency of the condensate water.

The first atomization member 332 further includes a plurality of first atomization holes 3322. The plurality of first atomization holes 3322 are arranged in the second main body 3321 and are densely arranged small holes. Thus, the contact area between the first atomization member 332 and the condensate water may be increased, so that a large amount of condensate water may be attached to the first atomization member 332. Moreover, the condensate water may also be atomized in an assisted manner, so that the atomization efficiency of the condensate water is improved. Here, atomizing the condensate water may be understood as crushing the condensate water into fine droplets.

It should be noted that when the condensate water enters the gap 333 between the reinforcement member 331 and the plurality of first atomization members 332 through the water intake hole 3312, due to the plurality of first atomization holes 3322 arranged, restricted by the surface tension, the condensate water cannot flow out from the first atomization holes 3322. Therefore, under the action of the centrifugal force generated by high-speed rotation of the rotary wheel 33, the condensate water may be atomized to water mist through the first atomization holes 3322 and is attached to the first heat exchanger 101 after a transient movement to be heated and evaporated.

In some embodiments, the first atomization member 332 may be made of a hydrophilic material. For example, the first atomization member 332 is coated with a coating consisting of high polymer materials such as methacrylic acid, butyl acrylate, styrene, and methyl methacrylate. Thus, the condensate water attached to the first atomization member 332 may be increased.

In some embodiments, the first atomization member 332 may be made of a material with high corrosion resistance and fatigue strength, so that the mechanical performance of the first atomization member 332 is improved, and the service life of the first atomization member 332 is prolonged.

In some embodiments, as shown in FIG. 6E and FIG. 6F, in a direction close to the first heat exchanger 101, the diameter of the first atomization member 332 is increased, and a side surface 3323 of the first atomization member 332 is obliquely arranged relative to the axial direction of the first atomization member 332. For example, a first angle between the side surface 3323 of the first atomization member 332 and the axial direction of the first atomization member 332 is a. The first a is a draft angle of the first atomization member 332, is greater than a first preset value, and is less than or equal to a second preset value, as shown in formula (1):

arctan ⁢ W 2 ⁢ ( L - H ) < α ≤ 90 ⁢ ° ( 1 )

Here, W is a distance between two adjacent sub-heat exchangers 1011, L is a height of the first heat exchanger 101, and H is a shortest distance between the connecting member 334 in the second direction and the top of the first heat exchanger 101.

When the first angle a is within the above range, the first atomization member 332 may throw the water mist obliquely upward, so that the throwing angle of the condensate water is increased. The thrown condensate water may reach the top of the first heat exchanger 101 farthest, so that the contact area between the atomized condensate water and the first heat exchanger 101 is increased, thereby increasing the evaporation rate of the condensate water.

When the first angle a is greater than 90°, a part of the thrown condensate water is unlikely to contact with the first heat exchanger 101, so that the evaporation rate of the condensate water is decreased. Moreover, the condensate water is easily thrown to other components of the portable air conditioner 1, so that other components are easily damaged. When the first angle a is less than or equal to a lower limit value of the above range, the thrown condensate water is unlikely to contact with the top of the first heat exchanger 101, so that the contact area between the atomized condensate water and the first heat exchanger 101 is increased, thereby decreasing the evaporation rate of the condensate water.

It should be noted that the draft angle may be understood as an inclination angle of a workpiece contacting with a parting surface of a mold set to make the workpiece easily separated from the mold. The parting surface of the mold is a separable surface of the mold contacting with the workpiece.

In some embodiments, as shown in FIG. 6A, the plurality of first atomization member 332 are symmetrically arranged relative to the connecting member 334. The first parts of first atomization members 332 in the plurality of first atomization members 332 may include two or more first atomization members 332, and the second parts of first atomization members 332 in the plurality of first atomization members 332 may include two or more first atomization members 332. The first parts of first atomization members 332 and the second parts of first atomization members 332 are symmetrically arranged about the connecting member 334. The first angles a of the two symmetrical first atomization members 332 are the same, so that the water-lifting stability of the rotary wheel 33 may be improved.

For example, the rotary wheel 33 includes eight first atomization members 332 to form eight atomizing surfaces. In the eight first atomization members 332, four first atomization members 332 are the first parts of first atomization members 332 and the remaining four first atomization members 332 are the second parts of first atomization members 332. The four first parts of first atomization members 332 and the four second parts of first atomization members 332 are symmetrical relative to the connecting member 334, respectively, so that the atomizing surfaces on the left and right sides of the connecting member 334 may also be symmetrically arranged pairwise. In some embodiments, the atomizing surfaces on the left and right sides of the connecting member 334 may be disposed in a stack.

To facilitate description, in a direction away from the connecting member 334, the four first parts of first atomization members 332 are a No. 1 atomization member 301, a No. 2 atomization member 302, a No. 3 atomization member 303, and a No. 4 atomization member 304 in sequence; and in a direction away from the connecting member 334, the four second parts of first atomization members 332 are a No. 5 atomization member 305, a No. 6 atomization member 306, a No.7 atomization member 307, and a No. 8 atomization member 308 in sequence.

The No. 1 atomization member 301 and the No. 5 atomization member 305 are symmetrical relative to the connecting member 334, and the remaining first atomization members 332 are reasoned in sequence. It may be understood that the present disclosure is not limited to the eight first atomization members 332. The atomization speed of the water-lifting assembly 30 on the condensate water may be increased by increasing the quantity of the first atomization members 332.

In some embodiments, the first angles a of the plurality of first atomization members 332 may be equal, so that the uniformity of the atomization effect of the plurality of first atomization members 332 is improved. Here, the atomization effect may be understood as the capacity of crushing the condensate water into droplets. The stronger the atomization effect, the smaller the droplets and the more the droplets.

Alternatively, as shown in FIG. 6A, in the direction away from the connecting member 334, the first angles a of the plurality of first parts of first atomization members 332 are decreased; and in the direction away from the connecting member 334, the first angles a of the plurality of second parts of first atomization members 332 are decreased. Thus, the distribution uniformity of the water mist generated by the plurality of first atomization members 332 in each region of the surface of the first heat exchanger 101 may be improved, so that the atomization efficiency and the evaporation efficiency of the condensate water are further improved.

For example, the first angles a of the No. 1 atomization member 301 and the No. 5 atomization member 305 are greater than the first angles a of the remaining first atomization members 332. In the direction away from the connecting member 334, the first angles a of the No.1 atomization member 301, the No. 2 atomization member 302, the No. 3 atomization member 303, and the No. 4 atomization member 304 are decreased in sequence; and in the direction away from the connecting member 334, the first angles a of the No. 5 atomization member 305, the No. 6 atomization member 306, the No.7 atomization member 307, and the No. 8 atomization member 308 are decreased in sequence.

In some embodiments, as shown in FIG. 6G, a difference od of radii of two adjacent first atomization members 332 satisfies a formula (2) or a formula (3):

δ ⁢ d = D n - D 1 2 ⁢ ( n - 1 ) ( 2 ) δ ⁢ d = D n - D n - 1 2 ⁢ ( n - 1 ) ( 3 )

Here, D_n is a diameter of the largest first atomization member 332, D_n−1 is a diameter of the first atomization member 332 adjacent to the first atomization member 332 with the diameter of D_n, and D₁ is a diameter of the smallest first atomization member 332, n is the quantity of the first atomization members 332. Here, the radius of the first atomization member 332 may be understood as a half of an outer diameter of the first atomization member 332, and the diameter of the first atomization member 332 may be understood as the outer diameter of the first atomization member 332.

The difference δd of radii of the two adjacent first atomization members 332 is relevant to the quantity of the first atomization members 332, the diameter of the largest first atomization member 332, and the diameter of the first atomization member 332 adjacent to the largest first atomization member 332. With the increase of the quantity of the first atomization members 332, the difference δd of radii of the two adjacent first atomization members 332 is decreased, so that the production of the plurality of first atomization members 332 is facilitated. Alternatively, with the increase of the difference δd between the diameter of the largest first atomization member 332 and the diameter of the first atomization member 332 adjacent to the largest first atomization member 332, the difference δd of radii of the two adjacent first atomization members 332 is increased, so that the overall structural strength of the first atomization member 332 is improved, thereby improving the water-lifting stability of the first atomization member 332.

Since the plurality of first atomization members 332 may be symmetrically arranged. if the thickness M of the first atomization member 332 is greater than or equal to a half of the distance W between the two adjacent sub-heat exchangers 1011, the plurality of first atomization members 332 cannot be mounted between the two adjacent sub-heat exchangers 1011.

Therefore, in some embodiments, as shown in FIG. 6E, the thickness M of the first atomization member 332 is greater than 0 and is less than the half of the distance W between the two adjacent sub-heat exchangers 1011 (i.e., 0<M<W/2). For example, the thickness M is equal to W/6, W/5, W/4, or W/3.

Thus, there may be a gap between the first atomization member 332 and the sub-heat exchanger 1011. The gap may avoid a mounting difficulty of the first atomization member 332 due to the too thick first atomization member 332, or the first atomization member 332 may be prevented from being blocked by the first sub-heat exchanger 1011 during rotation and the atomized condensate water may be prevented from being hindered by the sub-heat exchanger 1011, so that the contact area between the atomized condensate water and the sub-heat exchanger 1011 is improved.

In some embodiments, as shown in FIG. 6D, the first atomization hole 3322 is rhombic and in a radially outward direction at the center of the first atomization member 332, the dimensions of the plurality of first atomization holes 3322 are increased. Here, the dimension of the first atomization hole 3322 may be understood as an area of the first atomization hole 3322.

Since the diameter of the first atomization member 332 is increased in the radially outward direction at the center of the first atomization member 332, the dimension of the first atomization hole 3322 is increased, so that the diameter variation trends of the first atomization hole 3322 and the first atomization member 332 are the same, and therefore, the distribution density of the first atomization hole 3322 on any diameter may be substantially the same, which is beneficial to improving the uniformity of the atomization effect of the plurality of atomization holes 3322. Moreover, under the action of the centrifugal force, the less the diameter of the first atomization member 332, the larger the stress of the part of the first atomization member 332 corresponding to this diameter. By decreasing the dimension of the first atomization hole 3322 at the center of the first atomization member 332, the structural strength at the center of the first atomization member 332 may be improved, and the overall balance of the first atomization member 332 may be improved.

In some embodiments, as shown in FIG. 6G, in the peripheral direction of the first atomization member 332, the quantity of the first atomization holes 3322 is N1. DI is the diameter of a circumference where the first atomization holes 3322 are located. LI is an arc length between two adjacent first atomization holes 3322 on the circumference, and the quantity N1, the diameter DI, and the arc length LI satisfy a formula (4):

N ⁢ 1 = π × DI / LI ( 4 )

In the peripheral direction of the first atomization member 332, the quantity N1 of the first atomization holes 3322 is the perimeter (i.e., π×DI) of the circumference where the first atomization holes 3322 are located divided by the arc length LI between the two adjacent first atomization holes 3322.

If the arc length LI between two adjacent first atomization holes 3322 is less than 1 mm, the distribution density of the first atomization holes 3322 is too great, resulting in a reduction of the structural strength of the first atomization member 332. If the arc length LI between two adjacent first atomization holes 3322 is greater than 4 mm, the distribution density of the first atomization holes 3322 is too less, resulting in a reduction of the atomization effect of the first atomization member 332.

Therefore, in some embodiments, the arc length LI between the two adjacent first atomization holes 3322 is greater than or equal to 1 mm and less than or equal to 4 mm (i.e., 1 mm≤LI≤4 mm) For example, the arc length LI between the two adjacent first atomization holes 3322 is equal to 1 mm, 2 mm, 3 mm, or 4 mm. Thus, the distribution density of the first atomization holes 3322 may be increased, and the atomization effect of the first atomization holes 3322 may be improved.

If the quantity N2 of the first atomization holes 3322 in the radial direction of the first atomization member 332 is greater than 0.09 times of the quantity N1, the distribution density of the first atomization holes 3322 is too great, resulting in a reduction of the structural strength of the first atomization member 332. If the quantity N2 of the first atomization holes 3322 in the radial direction of the first atomization member 332 is less than 0.05 times of the quantity N1, the distribution density of the first atomization holes 3322 is too less, resulting in a reduction of the atomization effect of the first atomization member 332.

Therefore, in some embodiments, the quantity of the first atomization holes 3322 in the radial direction of the first atomization member 332 is N2, and the quantity N2 is greater than or equal to 0.05 times of the quantity N1 (a third preset value) and less than or equal to 0.09 times of the quantity N1 (a fourth preset value) (i.e., 0.05N1≤N≤0.09N1). For example, the quantity N2 is equal to 0.05N1, 0.06N1, 0.07N1, 0.08N1, or 0.09N1.

To further improve the contact area between the atomized condensate water and the first heat exchanger 101, in some embodiments, the water-lifting assembly 30 is movable.

In some embodiments, as shown in FIG. 7A to FIG. 7C, the water-lifting assembly 30 includes a second driving member 41. The second driving member 41 is located in the water-collecting member 103 and may be an external rotor electric machine.

The water-lifting assembly 30 further includes a second atomization member 42. At least part of the second atomization member 42 is arranged in the water-collecting member 103. and the second atomization member 42 is in transmission connection with the second driving member 41.

The second driving member 41 may drive the second atomization member 42 to rotate. The rotating second atomization member 42 may drive the condensate water in the water-collecting member 103 to flow and atomize and throw the condensate water to the first heat exchanger 101. It should be noted that the second driving member 41 may control the rotation of the second atomization member 42 and prevent other components from being affected.

The portable air conditioner 1 further includes a mobile assembly 50. The mobile assembly 50 is connected to the water-lifting assembly 30, and the mobile assembly 50 is movable in the first direction. The mobile assembly 50 is configured to drive the water-lifting assembly 30 to move in the first direction. Here, the first direction may be a width direction (for example, a left-right direction) of the portable air conditioner 1, and is perpendicular to the second direction and the third direction.

For example, the mobile assembly 50 moves in the width direction of the first base 1001. Since the mobile assembly 50 is connected to the water-lifting assembly 30, the water-lifting assembly 30 may move together with the mobile assembly 50. Thus, the contact area between the condensate water atomized by the water-lifting assembly 30 and the first heat exchanger 101 is increased, the uniformity of the condensate water thrown to the first heat exchanger 101 by the water-lifting assembly 30 may be improved, the atomization effect and the evaporation efficiency of the condensate water are improved, and the heat dissipation effect of the first heat exchanger 101 is improved.

In some embodiments, as shown in FIG. 7A to FIG. 7C, the mobile assembly 50 includes a mobile wheel 52 (an outer wheel).

The mobile assembly 50 further includes a third driving member 51. The third driving member 51 is in transmission connection with the mobile wheel 52, and is located in the mobile wheel 52. The third driving member 51 is configured to drive the mobile wheel 52 to move in the first direction. The third driving member 51 may be an external rotor electric machine.

When the third driving member 51 drives the mobile wheel 52 to move in the first direction, the moving mobile wheel 52 will not affect the rotation of the second atomization member 42. Moreover, since the third driving member 51 and the second driving member 41 are two independent driving members, the rotating speed and direction of the mobile wheel 52 may be different from the rotating speed and direction of the second atomization member 42.

For example, as shown in FIG. 8, the outdoor portion 10 further includes a guiding portion 104. The guiding portion 104 is arranged on the first base 1001 and is spaced apart from the water-collecting member 103. The mobile wheel 52 is slidably arranged in the guiding portion 104. The guiding portion 104 extends in the first direction, and the first heat exchanger 101 also extends in the first direction. For example, the guiding portion 104 is a sliding groove, and the length directions of the guiding portion 104 and the first heat exchanger 101 are parallel to the first direction, respectively.

Thus, when the second atomization member 42 rotates in the water-collecting member 103 to atomize and throw the condensate water to the first heat exchanger 101, the mobile wheel 52 may slide in the guiding portion 104.

In some embodiments, a length of the guiding portion 104 in the first direction is substantially the same as the lengths of the water-collecting member 103 and the first heat exchanger 101 in the first direction. Thus, the contact area between the condensate water thrown by the water-lifting assembly 30 and the first heat exchanger 101 may be increased, so that the evaporation efficiency of the condensate water and the heat dissipation efficiency of the first heat exchanger 101 are improved.

In some embodiments, the mobile wheel 52 may be arranged in the guiding portion 104 in a clamped form, so that the moving stability of the mobile wheel 52 in the guiding portion 104 is improved. It may be understood that the mobile wheel 52 may also be replaced with a slide block or a pulley in belt transmission, so that the structure of the mobile assembly 50 is simplified, and the mobile assembly is mounted and maintained conveniently.

In some embodiments, as shown in FIG. 8, the portable air conditioner 1 further includes two limit switches. The two limit switches are arranged on two sides of the guiding portion 104 in the first direction, respectively, and are electrically connected to the third driving member 51, respectively. The two limit switches are configured to, when being triggered, control the transmission direction of the third driving member 51 to reverse. Here, the transmission direction may be understood as the rotating direction of the mobile wheel 52 driven by the third driving member 51.

For example, the two limit switches include a first limit switch 105 and a second limit switch 106. When the mobile assembly 50 moves to the first limit switch 105 along the guiding portion 104, the mobile wheel 52 touches the first limit switch 105, and the first limit switch 105 sends a signal to the third driving member 51, so that the third driving member 51 may drive the rotating direction of the mobile wheel 52 to be switched from a first rotating direction to a second rotating direction. When the mobile assembly 50 moves to the second limit switch 106 along the guiding portion 104, the mobile wheel 52 touches the second limit switch 106, and the second limit switch 106 sends a signal to the third driving member 51, so that the third driving member 51 may drive the rotating direction of the mobile wheel 52 to be switched from the second rotating direction to the first rotating direction.

Thus, the to-and-fro movement of the mobile assembly 50 may be achieved, so that the contact area between the thrown condensate water and the first heat exchanger 101 is increased, and the atomization efficiency and the evaporation efficiency of the condensate water are improved.

In some embodiments, as shown in FIG. 7A to FIG. 7C, the mobile assembly 50 further includes a connecting shaft 53. The connecting shaft 53 is connected between the mobile wheel 52 and the water-lifting assembly 30. For example, a first end of the connecting shaft 53 is connected to the second atomization member 42, and a second end of the connecting shaft 53 is connected to the mobile wheel 52.

In some embodiments, as shown in FIG. 7C, the mobile assembly 50 further includes a wire hole 54. The wire hole 54 penetrates through the connecting shaft 53 in the axial direction of the connecting shaft 53.

The mobile assembly 50 further includes a wire harness 55. The wire harness 55 is arranged in the wire hole 54 in a penetrating manner and electrically connected to the second driving member 41. Thus, circuit systems of the mobile assembly 50 and the water-lifting assembly 30 may be integrated through the wire harness 55, and the circuit systems of the two may extend to a controller 60 included in the portable air conditioner I together and are electrically connected to the controller 60, so that the controller 60 may control the circuit systems of the mobile assembly 50 and the water-lifting assembly 30.

It should be noted that the controller 60 may be a processor. The processor may include a central processing unit (CPU), a microprocessor, and an application specific integrated circuit (ASIC), and may be configured to execute corresponding operations described in the controller 60) when the processor executes programs stored in a non-transitory computer-readable medium coupled to the controller 60.

In some embodiments, as shown in FIG. 7C, the mobile assembly 50 further includes a first bearing 43. The first bearing 43 is arranged between the mobile wheel 52 and the connecting shaft 53.

In some embodiments, as shown in FIG. 7C, the mobile assembly 50 further includes a second bearing 44. The second bearing 44 is arranged between the second atomization member 42 and the connecting shaft 53.

Thus, through the first bearing 43 and the second bearing 44, the frictional force between the mobile wheel 52 and the connecting shaft 53 and the frictional force between the second atomization member 42 and the connecting shaft 53 may be reduced, so that the energy loss and friction are reduced, and the rotating efficiency of the second atomization member 42 and the mobile wheel 52 is improved. Moreover, the first bearing 43 and the second bearing 44 may support and position the mobile wheel 52 and the second atomization member 42, respectively, to prevent the mobile wheel 52 and the second atomization member 42 from deviating or swinging in a working process, thereby improving the stability of the mobile assembly 50 and the water-lifting assembly 30.

In some embodiments, the second atomization member 42 includes a first wheel hub main body 421. The first wheel hub main body 421 is in transmission connection with the third driving member 51.

The second atomization member 42 further includes a second wheel hub main body 422. The second wheel hub main body 422 is arranged on a peripheral side of the first wheel hub main body 421.

The second atomization member 42 further includes a plurality of second atomization holes 423. The plurality of second atomization holes 423 are arranged in the second wheel hub main body 422.

An atomization principle of the second atomization member 42 may refer to related contents above, which is not described repeatedly herein. Moreover, the material of the second atomization member 42 may be the same as the material of the first atomization member 332.

In some other embodiments, as shown in FIG. 7A to FIG. 7C, the second atomization member 42 includes a first wheel hub main body 421. The first driving member 41 is arranged in the first wheel hub main body 421 and is in transmission connection with the first wheel hub main body 421. The first wheel hub main body 421 is connected to the second bearing 44 through the connecting shaft 53. Thus, the second driving member 41 may drive the first wheel hub main body 421 to rotate, so that the second atomization member 42 rotates.

The second atomization member 42 further includes a second wheel hub main body 422. The second wheel hub main body 422 is arranged on a peripheral side of the first wheel hub main body 421.

The second atomization member 42 further includes a plurality of second atomization holes 423. The plurality of second atomization holes 423 are arranged in the second wheel hub main body 422.

In some embodiments, the portable air conditioner I may include a plurality of mobile assemblies 50, so that the moving stability of the water-lifting assembly 30 in the first direction is improved. For example, as shown in FIG. 7D, the portable air conditioner 1 includes two mobile assemblies 50. The two mobile assemblies 50 are arranged on two sides of the water-lifting assembly 30 in an axial direction.

It should be noted that in a case where the water-lifting assembly 30 is of a structure shown in FIG. 7A to FIG. 7D, the portable air conditioner I may further include a plurality of water-lifting assemblies 30.

For example, in a case where the first heat exchanger 101 includes two sub-heat exchangers 1011 and the two sub-heat exchangers 1011 are arranged in two water-collecting members 103, respectively; the portable air conditioner I may include two water-lifting assemblies 30. Two second atomization members 42 in the two water-lifting assemblies 30 are located in the two water-collecting members 103, respectively, and are close to the two second sub-heat exchangers 1011. Thus, the condensate water may be uniformly thrown to the first heat exchanger 101, and the atomization efficiency of the condensate water may further be improved.

In a case where the first heat exchanger 101 includes three sub-heat exchangers 1011, the portable air conditioner 1 may include two water-lifting assemblies 30. Two second atomization members 42 in the two water-lifting assemblies 30 are located between two adjacent sub-heat exchangers 1011, respectively.

Certainly, in some embodiments, the water-lifting assembly 30 may atomize the condensate water through a water pump and a spray pipe.

In some embodiments, as shown in FIG. 9A, FIG. 10A, and FIG. 10B, the water-lifting assembly 30 includes a first water pump 71. The first water pump 71 is arranged in the water-collecting member 103 and configured to extract the condensate water in the water-collecting member 103 and increase the pressure of the condensate water. For example, when a water level in the water-collecting member 103 reaches a first preset water level, the first water pump 71 is started to extract the condensate water.

The water-lifting assembly 30 further includes a spray pipe 72. The spray pipe 72 is in communication with a water outlet of the first water pump 71 and is close to the first heat exchanger 101. The spray pipe 72 extends in the second direction.

In some examples, as shown in FIG. 9B, the spray pipe 72 includes a pipe main body 721 (a spray pipe main body). The pipe main body 721 is in communication with the water outlet of the first water pump 71.

As shown in FIG. 11A and FIG. 11B, the spray pipe 72 further includes a plurality of first spray holes 723. The plurality of spray holes 723 are arranged in the pipe main body 721 and spaced apart from each other in a second direction (equally spaced). The plurality of first spray holes 723 are arranged toward the first heat exchanger 101 to increase the contact area between the first heat exchanger 101 and the condensate water, so that the atomization efficiency of the condensate water and the uniformity of water mist distribution are improved. For example, the plurality of first spray holes 723 face fins 124.

A working principle of the first water pump 71 is as follows: when a liquid pressurized by the first water pump 71 is ejected from the narrow first spray holes 723, the liquid has a high kinetic energy. In the moving process of the liquid, due to instability, a part of the liquid falls off from a jet flow and becomes fine fogdrops. Meanwhile, in a short moving path of the liquid, when a water flow flowing at a high speed collides with a stationary solid surface (for example, the surface of the first heat exchanger 101, the water flow is crushed to form atomized particles (i.e., droplets). The atomized particles are attached to the first heat exchanger 101 to be heated and evaporated and are taken away by air flowing in the outdoor portion 10, so that the condensate water in the water-collecting member 103 is discharged.

The condensate water pumped by the first water pump 71 is pressurized by the first water pump 71 and flows out from the water outlet. The condensate water flowing out from the water outlet flows into the spray pipe 72 and is sprayed from the first spray hole 723 at a high speed to form a jet flow. The jet flow collides with the first heat exchanger 101 and is crushed into fine droplets, and the droplets are attached to the first heat exchanger 101. Then, the droplets absorb heat to evaporate and are discharged along with air flowing in the outdoor portion 10.

It should be noted that the condensate water pressurized by the first water pump 71 may have a high speed after being sprayed from the first spray hole 723. The high-speed condensate water may improve the generation efficiency and quantity of the droplets. In addition, the condensate water collides with the first heat exchanger 101 to generate the droplets, so that the evaporation rate of the condensate water may be increased, and the amount of the condensate water taken away by the air flowing in the outdoor portion 10 may be increased.

In some embodiments, the water-lifting assembly 30 further includes a plurality of spray pipes 72. For example, as shown in FIG. 9A, the water-lifting assembly 30 includes two spray pipes 72. The two spray pipes 72 are spaced apart from each other in the first direction.

In a case where the first heat exchanger 101 includes one sub-heat exchanger 1011, the two spray pipes 72 may be located on at least one side of the first heat exchanger 101 in the third direction and may be close to two sides of the first heat exchanger 101 in the first direction.

In a case where the first heat exchanger 101 includes a first sub-heat exchanger 121 and a second sub-heat exchanger 122, the two spray pipes 72 are arranged between the first sub-heat exchanger 121 and the second sub-heat exchanger 122 and are close to two sides of the first sub-heat exchanger 121 or the second sub-heat exchanger 122 in the first direction, respectively. Heights of the plurality of first spray holes 723 in one spray pipe 72 may be the same as the heights of the plurality of first spray holes 723 in the other spray pipe 72. One of the two spray pipes 72 may be arranged toward one of the first sub-heat exchanger 121 and the second sub-heat exchanger 122, and the other of the two spray pipes 72 may be arranged toward the other of the first sub-heat exchanger 121 and the second sub-heat exchanger 122. Thus, the contact area between the condensate water and the two sub-heat exchangers 1011 may be increased, so that the utilization ratio of the first heat exchanger 101 is improved.

In some embodiments, a flow velocity V of the condensate water at the first spray hole 723 satisfies a formula (5):

v = Q Np × π ⁢ Dp 2 4 ( 5 )

Here, Q is a flow of the first water pump 71, Np is the quantity of the first spray holes 723, and Dp is a diameter of the first spray holes 723.

In some embodiments, the diameter of the spray pipe 72 may be 5 mm. The diameter of the spray pipe 72 is relevant to the flow velocity needed by the condensate water at the first spray hole 723. The less the diameter of the spray pipe 72, the greater the flow velocity of the condensate water flowing in the spray pipe 72. Certainly, the diameter of the spray pipe 72 may also be other numerical values.

If the flow velocity V is less than 20 m/s, the kinetic energy of the condensate water sprayed from the first spray hole 723 is reduced, and the atomization effect when the condensate water collides with the first heat exchanger 101 is reduced. If the flow velocity V is greater than 30 m/s, the diameter of the first spray hole 723 is decreased, and the processing difficulty is increased.

Therefore, in some embodiments, the flow velocity V may be greater than or equal to 20 m/s and less than or equal to 30 m/s. For example, the flow velocity is 20 m/s, 23 m/s, 25 m/s, 28 m/s, or 30 m/s. Thus, the jet flow sprayed from the first spray hole 723 may generate a lot of fine fogdrops (i.e., droplets) after colliding with the first heat exchanger 101, so that the atomization efficiency and the evaporation efficiency of the condensate water are improved.

If the flow of the first water pump 71 is less than 3.5 L/min, the velocity at which the first water pump 71 extracts the condensate water in the water-collecting member 103 is less than the generation velocity of the condensate water, and the condensate water is easy to spill over the water-collecting member 103. If the flow Q of the first water pump 71 is greater than 4.5 L/min, the velocity at which the first water pump 71 extracts the condensate water in the water-collecting member 103 is greater than the generation velocity of the condensate water, and the first water pump 71 is unlikely to extract the condensate water, resulting in reduction of the working stability of the first water pump 71.

Therefore, in some embodiments, the flow Q of the first water pump 71 may be greater than or equal to 3.5 L/min and less than or equal to 4.5 L/min. For example, the flow Q is equal to 3.5 L/min, 3.75 L/min, 4.0 L/min, 4.25 L/min, or 4.5 L/min. Thus, the jet flow sprayed from the first spray hole 723 may generate a lot of fine fogdrops after colliding with the first heat exchanger 101, so that the atomization efficiency and the evaporation efficiency of the condensate water are improved.

If the quantity Np of the first spray holes 723 is less than 7, the flow velocity of the condensate water sprayed from the first spray holes 723 is increased, the diameter of the first spray holes 723 is decreased, and the processing difficulty is increased. If the quantity Np of the first spray holes 723 is greater than 9, the flow velocity of the condensate water sprayed from the first spray holes 723 is decreased, and the atomization effect when the condensate water collides with the first heat exchanger 101 is reduced.

Therefore, in some embodiments, the quantity Np of the first spray holes 723 is greater than or equal to 7 and less than or equal to 9. For example, the quantity Np of the first spray holes 723 is equal to 7, 8, or 9. Thus, the contact area between the jet flow sprayed from the first spray hole 723 and the first heat exchanger 101 may be increased, so that the evaporation efficiency of the condensate water is improved.

It should be noted that the quantity and positions of the first spray holes 723 may be set according to the height of the first heat exchanger 101.

If the diameter Dp of the first spray hole 723 is less than 0.3 mm, the jet flow sprayed from the first spray hole 723 is fine, resulting in a reduction of the evaporation efficiency of the condensate water and a decrease of the discharge rate of the condensate water. If the diameter Dp of the first spray hole 723 is greater than 0.5 mm, the jet flow sprayed from the first spray hole 723 is thick. In this case, the kinetic energy of the jet flow is less than the kinetic energy of the corresponding jet flow when the diameter Dp is less than 0.5 mm, in the moving process of the jet flow, due to instability of the jet flow, a large part of the liquid falls of from the jet flow, and a small part of the liquid collides with the fins 124 of the first heat exchanger 101 to generate mist spray, resulting in reduction of the evaporation efficiency of the condensate water.

Therefore, in some embodiments, the diameter Dp of the first spray hole 723 is greater than or equal to 0.3 mm and less than or equal to 0.5 mm. For example, the diameter Dp is equal to 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, or 0.5 mm. Thus, the quantity of the fogdrops generated by the collision of the jet flow sprayed from the first spray hole 723 and the first heat exchanger 101, and the volume of the fogdrops may be increased, so that the fogdrops are discharged out of the outdoor portion 10 with the flowing air.

It may be understood that the distribution uniformity of the droplets may be improved by adjusting the distribution positions of the first spray holes 723, so that the utilization ratio of heat of the first heat exchanger 101 is improved. The velocity of the jet flow may be adjusted by adjusting the diameter Dp and the quantity Np of the first spray holes 723, so that the atomization effect of the water-lifting assembly 30 on the condensate water is improved.

In some embodiments, as shown in FIG. 12A to FIG. 12C, the axial direction of the first spray hole 723 and the first heat exchanger 101 are arranged at an acute angle, so that the condensate water is sprayed to the first heat exchanger 101. For example, the direction in which the condensate water is sprayed from the first spray hole 723 and the length direction of the first heat exchanger 101 are arranged at an acute angle.

The condensate water sprays the jet flow from the first spray hole 723, the jet flow and the first heat exchanger 101 form an included angle, and the included angle is an acute angle. Moreover, the jet may be sprayed between two adjacent fins 124 to improve the contact area between the droplets generated by the jet flow colliding with the first heat exchanger 101 and the first heat exchanger 101 and improve the utilization ratio of heat of the first heat exchanger 101, so that the atomization efficiency and the evaporation efficiency of the condensate water are improved.

If a second included angle θ between the axial direction of the first spray hole 723 and the first heat exchanger 101 is less than 78°, and the contact area between the condensate water sprayed from the first spray hole 723 and the first heat exchanger 101 is small, resulting in reduction of the atomization efficiency. If the second included angle θ between the axial direction of the first spray hole 723 and the first heat exchanger 101 is less than 82°, the flow direction of the condensate water sprayed from the first spray hole 723 is substantially parallel to the first heat exchanger 101, and the condensate water cannot be sprayed to the first heat exchanger 101.

Therefore, in some embodiments, as shown in FIG. 12A to FIG. 12C, the second included angle θ between the axial direction of the first spray hole 723 and the first heat exchanger 101 is greater than or equal to 78° and less than or equal to 82° (i.e., 78°≤θ≤82°). For example, the second included angle θ is equal to 78°, 79°, 80°, 81°, or 82°. Thus, the atomization effect of the jet flow impacting the fins 124 may be improved, the contact area between the water mist and the first heat exchanger 101 is increased, and the utilization ratio of heat of the first heat exchanger 101 is improved.

In some embodiments, as shown in FIG. 13A to FIG. 13B, in a case where the first heat exchanger 101 includes a first sub-heat exchanger 121 and a second sub-heat exchanger 122, the spray pipe 72 is arranged between the first sub-heat exchanger 121 and the second sub-heat exchanger 122, and the plurality of first spray holes 723 are arranged toward the first sub-heat exchanger 121 or the second sub-heat exchanger 122 to improve the atomization efficiency of the condensate water.

In some examples, as shown in FIG. 12B, the plurality of first spray holes 723 are arranged toward the first heat exchanger 121. The jet flow formed by spraying the condensate water from the plurality of first spray holes 723 is sprayed to the first sub-heat exchanger 121 and impacts the first sub-heat exchanger 121 to generate fine and dense water mist. Alternatively, as shown in FIG. 12C, the plurality of first spray holes 723 are arranged toward the second heat exchanger 122. The jet flow formed by spraying the condensate water from the plurality of first spray holes 723 is sprayed to the second sub-heat exchanger 122 and impacts the second sub-heat exchanger 122 to generate fine and dense water mist.

In some embodiments, in a case where the water-lifting assembly 30 includes two spray pipes 72 and the first heat exchanger 101 includes the first sub-heat exchanger 121 and the second sub-heat exchanger 122, the two spray pipes 72 include a first spray pipe 7201 and a second spray pipe 7202.

As shown in FIG. 12D, the first spray pipe 7201 faces the first sub-heat exchanger 121, and the second spray pipe 7202 faces the second sub-heat exchanger 122. A second included angle θ between the first spray pipe 7201 and the first sub-heat exchanger 121 is greater than or equal to 78° and less than or equal to 82°. A second included angle θ between the second spray pipe 7202 and the second sub-heat exchanger 122 is greater than or equal to 78° and less than or equal to 82°. Alternatively, as shown in FIG. 12E, the first spray pipe 7201 faces the second sub-heat exchanger 122, and the second spray pipe 7202 faces the second sub-heat exchanger 121. A second included angle θ between the first spray pipe 7201 and the second sub-heat exchanger 122 is greater than or equal to 78° and less than or equal to 82°. A second included angle θ between the second spray pipe 7202 and the first sub-heat exchanger 121 is greater than or equal to 78° and less than or equal to 82°.

Thus, the contact area between the water mist and the two sub-heat exchangers 1011 may be increased, so that the utilization ratio of the first heat exchanger 101 is improved.

In some embodiments, as shown in FIG. 9B, FIG. 11A, and FIG. 11B, the spray pipe 72 further includes two fixed portions 722 (fixed baffles), and the two fixed portions 722 are arranged on two sides of the pipe main body 721 in the radial direction, respectively. The two fixed portions 722 are fixedly connected to the first heat exchanger 101. Thus, the pipe main body 721 may be fixed on the first heat exchanger 101 through the fixed portions 722, so that the spray pipe 72 is fixedly mounted, and it is convenient to improve the stability of the spray pipe 72.

In some embodiments, as shown in FIG. 9A, FIG. 13A, and FIG. 13B, the fixed portions 722 are connected to the fins 124.

For example, as shown in FIG. 12A, the fixed portion 722 includes a first insertion portion 7221, and the fin 124 includes a second insertion portion 1241 (as shown in FIG. 9B). The first insertion portion 7221 and the second insertion portion 1241 are inserted, so that the spray pipe 72 is fixed between two adjacent fins 124, which simplifies mounting and detachment of the spray pipe 72.

In some embodiments, the first insertion portion 7221 may be one of a slot and a protrusion, the second insertion portion 1241 may be the other of the slot and the protrusion, and the slot and the protrusion are in insertion fit.

Taking the water-lifting assembly 30 includes two spray pipes 72 as an example, description will be made below.

In some embodiments, as shown in FIG. 9A, FIG. 13C, and FIG. 14, in a case where the water-lifting assembly 30 includes a plurality of spray pipes 72, the water-lifting assembly 30 further includes a first water division pipe 73 (a main water division pipe). A first end of the first water division pipe 73 is in communication with the water outlet of the first water pump 71.

The water-lifting assembly 30 further includes two second water division pipes 74 (branch water division pipes). A second end of the first water division pipe 73 is in communication with first ends of the two second water division pipes 74 and second ends of the two second water division pipes 74 are in communication with the two spray pipes 72, respectively.

The first water division pipe 73 leads the condensate water in the first water pump 71 out, and the two second water division pipes 74 divide the condensate water from the first water division pipe 73 into two parts. A first part of condensate water flows into one second water division pipe 74 and enters one spray pipe 72 from this second water division pipe 74. A second part of condensate water flows into the other second water division pipe 74 and enters the other spray pipe 72 from this second water division pipe 74. Thus, the condensate water extracted by the first water pump 71 may be led to the two spray pipes 72, respectively, to be atomized, so that the amount of the atomized condensate water is improved.

In some embodiments, a diameter of the second water division pipe 74 is greater than a diameter of the spray pipe 72, so that the second water division pipe 74 is connected to the spray pipe 72.

In some embodiments, as shown in FIG. 14, the water-lifting assembly 30 further includes a flow dividing pipe 75 (for example, a three-way pipe). The flow dividing pipe 75 is arranged between the first water division pipe 73 and the two second water division pipes 74 to divide a flow path of the condensate water into two parts.

In some embodiments, the first water division pipe 73 and the second water division pipe 74 may be silica gel hoses, so that the first water division pipe 73 and the second water division pipe 74 are mounted and arranged conveniently, which prevents the first water division pipe 73 and the second water division pipe 74 from contacting with the first heat exchanger 101.

In some embodiments, the water-lifting assembly 30 may also adjust the atomization efficiency on the condensate water according to different water levels in the water-collecting member 103.

In some embodiments, as shown in FIG. 15A and FIG. 15B, the water-lifting assembly 30 includes a fourth driving member 81. The fourth driving member 81 is arranged at a bottom of the outdoor portion 10. For example, the fourth driving member 81 is arranged on the first base 1001. The fourth driving member 81 is configured to start when the water level in the water-collecting member 103 is less than a preset water level. The first preset water level may be set according to the volume of the water-collecting member 103 and the flow of the second water pump 84.

The water-lifting assembly 30 further includes a second rotary shaft 82. The second rotary shaft 82 is in transmission connection with the fourth driving member 81. For example, a first end of the second rotary shaft 82 is in transmission connection with the fourth driving member 81.

The water-lifting assembly 30 further includes a third atomization member 83. At least part of the third atomization member 83 is arranged in the water-collecting member 103, and the third atomization member 83 is in transmission connection with the second rotary shaft 82. For example, a second end of the second rotary shaft 82 is in transmission connection with the third atomization member 83. Thus, when the fourth driving member 81 drives the second rotary shaft 82 to rotate, the third atomization member 83 may rotate along with the second rotary shaft 82. In the rotating process of the third atomization member 83, the third atomization member 83 may lift the condensate water and atomize the condensate water quickly.

It should be noted that in a case where the first heat exchanger 101 includes at least two sub-heat exchangers 1011, the water-lifting assembly 30 may include one or more third atomization members 83. The third atomization members 83 may be arranged between two adjacent sub-heat exchangers 1011.

As shown in FIG. 16, the water-lifting assembly 30 further includes a second water pump 84. At least part of the second water pump 84 is arranged in the water-collecting member 103, and is in communication with the third atomization members 83. The second water pump 84 is configured to start when the water level in the water-collecting member 103 is greater than the preset water level.

When the water level in the water-collecting member 103 is lower than the first preset water level, the fourth driving member 81 starts to drive the third atomization member 83 to rotate to atomize the condensate water into water mist. When the water level in the water-collecting member 103 is lower than the first preset water level, the second rotary shaft 82 is driven by the fourth driving member 81 to rotate, so that the third atomization member 83 rotates to atomize the condensate water. In this case, the atomization mode is centrifugal atomization.

When the water level in the water-collecting member 103 is higher than the first preset water level, the fourth driving member 81 stops operating, and the second water pump 84 starts to pump the condensate water into the third atomization member 83. The condensate water is sprayed from the third atomization member 83 in the form of a jet flow. In the process that the condensate water is sprayed, the centrifugal force and counter-acting force of the jet flow may push the second rotary shaft 82 and the third atomization member 83 to rotate to increase the spray angle of the condensate water, so as to achieve multi-angle atomization. In the above process, the high-speed jet flow sprayed from the third atomization member 83 may impact a wall surface of the third atomization member 83 to be atomized secondarily. In the above process, the atomization mode includes centrifugal atomization and jet flow impact atomization.

It should be noted that when the water level in the water-collecting member 103 is greater than the first preset water level (i.e., the amount of the condensate water is large), in a mode of atomizing the condensate water through the second spray hole 833, the flow velocity of the jet flow sprayed from the second spray hole 833 is high, so that the fineness of the droplets formed by the condensate water impacting the first heat exchanger 101 may be improved, thereby improving the atomization effect. Meanwhile, the water mist formed by the second spray hole 833 may be fan-shaped, so that the cover area of the water mist is increased, and the atomization dead zone is reduced.

In some examples, as shown in FIG. 16, the portable air conditioner 1 further includes a water level sensor 90. The water level sensor 90 is arranged in the water-collecting member 103 and is electrically connected to the fourth driving member 81 and the second water pump 84. The water level sensor 90 is configured to detect the water level in the water-collecting member 103 to control the start and stop of the fourth driving member 81 and the second water pump 84. For example, the water level sensor 90 is configured to detect whether the water level in the water-collecting member 103 reaches the first preset water level.

In some other examples, as shown in FIG. 16, the portable air conditioner 1 further includes a plurality of water level sensors 90. The plurality of water level sensors 90 include first sub-water level sensors 91 and second sub-water level sensors 92. The first sub-water level sensors 91 are configured to determine whether the water level in the water-collecting member 103 reaches the first preset water level, so as to control the start and stop of the fourth driving member 81 and the second water pump 84. The second sub-water level sensors 92 are configured to determine whether water in the water-collecting member 103 is full (for example, the water level in the water-collecting member 103 is greater than or equal to a second preset water level), so as to prevent the condensate water in the water-collecting member 103 from spilling over.

It should be noted that upon determining that water in the water-collecting member 103 is full, the second sub-water level sensors 92 may send signals to a prompt device connected, where the prompt device is configured to prompt that water in the water-collecting member 103 is full. The prompt device may be a display, a loudspeaker, an alarm light, or a terminal device on the portable air conditioner 1. The prompt device may perform prompting by way of characters, pictures, sounds, light, or the like.

The third atomization member 83 will be introduced below.

In some embodiments, as shown in FIG. 17A. FIG. 17B, and FIG. 17D, the third atomization member 83 includes a third main body 830.

The third atomization member 83 further includes a plurality of atomization regions 831. The plurality of atomization regions 831 are arranged in sequence in a circumferential direction of the third main body 830. The plurality of atomization regions 831 are different regions on the third main body 830.

The third atomization member 83 further includes a plurality of second spray holes 833. The plurality of second spray holes 833 are arranged in the plurality of atomization regions 831, respectively. The second spray holes 833 are located at a position, close to a center of a circle of the third main body 830, of the corresponding atomization region 831. The plurality of second spray holes 833 are in communication with the second water pump 84 and are configured to spray and atomize the condensate water. Thus, the atomization effect of the third atomization member 83 on the condensate water may be improved, so that the cover area of the water mist formed by atomization is increased, and the atomization dead zone is reduced. Here, the atomization dead zone may be understood that a region which cannot be covered by the water mist in the outdoor portion 10.

In some embodiments, as shown in FIG. 17E, the second spray holes 833 are elliptical. Moreover, the third atomization member 83 further includes an atomization portion 836, and the atomization portion 836 is configured to crush the jet flow sprayed from the second spray hole 833 to atomize the condensate water. The atomization portion 836 is arranged on the third main body 830, and an extension direction of the atomization portion 836 is perpendicular to the axial direction of the second spray hole 833. For example, the atomization portion 836 is a groove, and the groove is in communication with the second spray hole 833. The axial direction of the second spray hole 833 and a depth direction (i.e., the extension direction of the atomization portion 836) of the groove are perpendicular to each other, and the groove and the second spray hole 833 may be elliptical. Thus, the jet flow sprayed from the second spray hole 833 may be crushed due to collision with the groove to be atomized, so that the atomization area of the condensate water is increased, and the atomization dead zone is reduced.

The third atomization member 83 further includes a plurality of atomization holes 834, and the plurality of atomization holes 834 are arranged in the third main body 830 and located in the plurality of atomization regions 831. For example, the third atomization holes 834 are arranged at a position, close to an edge of the third main body 830, of the atomization regions 831. Two or more third atomization holes 834 may be arranged in any atomization region 831.

The condensate water may be taken out from the water-collecting member 103 through the third atomization holes 834 and atomized, so that the atomization dead zone is reduced, and the atomization effect and the atomization rate of the condensate water are improved.

In some embodiments, as shown in FIG. 18B, the third atomization hole 834 includes a first sub-hole 837 (a main hole).

The third atomization hole 834 further includes a plurality of second sub-holes 838. The plurality of second sub-holes 838 are arranged around the first sub-hole 837 and are in communication with the first sub-hole 837. A bending direction of the second sub-hole 838 is the same as the rotating direction of the second rotary shaft 82, so that the atomization effect of the third atomization hole 834 on the condensate water is improved.

A diameter of the second sub-hole 837 is greater than a dimension P of the second sub-hole 838 in a target direction. The second sub-hole 838 is crescent-shaped. Moreover, in a direction away from the first sub-hole 837, the dimension of the second sub-hole 838 in the target direction is decreased. Here, the target direction is a direction perpendicular to an extension direction K of the second sub-hole 838. Thus, in the third atomization hole 834, with the decrease of the dimension of a flow channel, the flow rate of the condensate water is increased, so that the atomization effect of the third atomization hole 834 on the condensate water is improved.

In some embodiments, the second sub-hole 838 consists of a part of a first circle 8381 and a part of a second circle 8382. The first circle 8381 and the second circle 8382 are internally tangent. The second circle 8382 and the first sub-hole 837 are externally tangent. A diameter of the first circle 8381 is greater than a diameter of the second circle 8382.

For example, the second sub-hole 838 includes a third curved surface 8383. The third curved surface 8383 is a part of the first circle 8381.

The second sub-hole 838 further includes a fourth curved surface 8384. The fourth curved surface 8384 is a part of the second circle 8382. A first end of the third curved surface 8383 is tangent to a first end of the fourth curved surface 8384, a second end of the third curved surface 8383 is tangent to another second sub-hole 838, and a second end of the fourth curved surface 8384 is tangent to the first sub-hole 837, thereby forming the second sub-hole 838.

If the radius R3 of the first sub-hole 837 is less than 4 mm, the dimension of the first sub-hole 837 is decreased, resulting in an increase in the processing difficulty. If the radius R3 of the first sub-hole 837 is greater than 8 mm, the dimension of the first sub-hole 837 is increased, resulting in a reduction of the structural strength of the first atomization member 83. If the radius R4 of the first circle 8381 is less than 3 mm, the dimension of the second sub-hole 838 is decreased, resulting in an increase in the processing difficulty. If the radius R4 of the first circle 8381 is greater than 6 mm, the dimension of the second sub-hole 838 is increased. resulting in a reduction of the structural strength of the first atomization member 83. If the radius R5 of the second circle 8382 is less than 2 mm, the dimension of the second sub-hole 838 is decreased, resulting in an increase in the processing difficulty. If the radius R5 of the second circle 8382 is greater than 4 mm, the dimension of the second sub-hole 838 is increased. resulting in a reduction of the structural strength of the first atomization member 83.

Therefore, in some embodiments, as shown in FIG. 18B, the radius R3 of the first sub-hole 837 is greater than or equal to 4 mm and less than or equal to 8 mm (i.e., 4 mm≤R3≤8 mm). For example, the radius R3 of the first sub-hole 837 is equal to 4 mm, 5 mm, 6 mm, 7 mm, or 8 mm.

The radius R4 of the first circle 8381 is greater than or equal to 3 mm and less than or equal to 6 mm (i.e., 3 mm≤R4≤6 mm). For example, the radius R4 of the first circle 8381 is equal to 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, or 6 mm.

Moreover, the radius R5 of the second circle 8382 is greater than or equal to 2 mm and less than or equal to 4 mm (i.e., 2 mm≤R5<4 mm). For example, the radius R5 of the second circle 8382 is equal to 2 mm, 2.5 mm, 3 mm, 3.5 mm, or 4 mm.

That is to say, the radius of the third curved surface 8383 is any value within a range of 3-6 mm, the radius of the fourth curved surface 8384 is any value within a range of 2-4 mm. and the radius of the first sub-hole 837 is any value within a range of 4-8 mm. Thus, the amount of the atomized condensate water may be increased, and the atomization effect of the third atomization hole 834 on the condensate water is improved.

In some embodiments, as shown in FIG. 17A and FIG. 17B, the third atomization member 83 further includes a plurality of fan blades 832. The plurality of fan blades 832 are arranged on the third main body 830 and protrude relative to the third main body 830 in the axial direction of the third main body 830. The plurality of fan blades 832 are spaced apart from each other in the circumferential direction of the third main body 830, so that a plurality of atomization regions 831 may be spaced on the third main body 830. The atomization regions 831 are located between two adjacent fan blades 832. The plurality of second spray holes 833 are arranged toward the plurality of fan blades 832, respectively.

By arranging the plurality of fan blades 832, the amount of the condensate water thrown by the third atomization member 83 may be increased, and the atomization efficiency of the condensate water may be improved.

In some embodiments, as shown in FIG. 17A and FIG. 17B, the fan blade 832 is arc-shaped, and a bending direction of the fan blade 832 is consistent with the rotating direction of the third atomization member 83. Thus, the condensate water sprayed from the second spray hole 833 may be fan-shaped, so that the cover area of the water mist is increased, and the atomization dead zone is reduced.

For example, as shown in FIG. 17B, the second spray hole 833 faces the first curved surface 8321 (an outer curved surface) of an adjacent fan blade 832. When the condensate water is sprayed from the second spray hole 833, the condensate water may impact the first curved surface 8321 of an adjacent fan blade 832, and the impact point is substantially located in a middle part of the first curved surface 8321. Thus, a reaction thrust generated by the jet flow sprayed from the second spray hole 833 at a high speed may drive the second rotary shaft 82 to rotate, and the jet flow sprayed from the second spray hole 833 impacting the first curved surface 8321 of the fan blade 832 is crushed to be atomized secondarily, so that centrifugal atomization and jet flow impact atomization are combined, thereby improving the atomization effect and the atomization rate of the condensate water and further preventing frequent water discharge of the portable air conditioner 1 in a high-humidity environment.

If the thickness of the fan blade 832 is less than 2.5 mm, the fan blade 832 is thin, so that in the rotating process of the third atomization member 83, the fan blade 832 deforms easily due to resistance of the condensate water, which affects the atomization efficiency of the third atomization member 83. If the thickness of the fan blade 832 is greater than 3.5 mm, the fan blade 832 is thick, so that the rotating resistance of the third atomization member 83 is increased, which affects the atomization efficiency of the third atomization member 83.

In some embodiments, the thickness T of the fan blade 832 is greater than or equal to 2.5 mm and less than or equal to 3.5 mm (i.e., 2.5 mm≤T≤3.5 mm), so that the structural stability of the fan blade 832 is improved. For example, the thickness T of the fan blade 832 is equal to 2.5 mm, 2.75 mm, 3.0 mm, 3.25 mm, or 3.5 mm.

If a central angle β corresponding to two adjacent fan blades 832 is less than 45°, the quantity of the fan blades 832 is great, so that the rotating resistance of the third atomization member 83 is increased, which affects the atomization efficiency of the third atomization member 83. If the central angle β corresponding to two adjacent fan blades 832 is greater than 90°, the quantity of the fan blades 832 is less, so that the cover area of the water mist is decreased, and the structural strength of the third atomization member 83 is reduced, which affects the atomization efficiency of the third atomization member 83.

In some embodiments, as shown in FIG. 18A, the central angle β corresponding to two adjacent fan blades 832 is greater than or equal to 45° and less than or equal to 90° (i.e., 45°≤B≤90°). Thus, the quantity of the fan blades 832 may be controlled by adjusting the central angle β, so that the contact area between the fan blades 832 and the condensate water within a unit time is increased, and the atomization efficiency of the condensate water is improved.

If a difference between an outer radius R1 and an inner radius R2 of the fan blade 832 is less than 3 mm, the strength of the fan blade 832 is reduced, and the structural strength of the third atomization member 83 is reduced, which affects the stability of the third atomization member 83. If the difference between the outer radius RI and the inner radius R2 of the fan blade 832 is greater than 6 mm, the size and weight of the fan blade 832 are increased, resulting in an increase in the rotating resistance of the third atomization member 83, which affects the atomization efficiency of the third atomization member 83.

In some embodiments, as shown in FIG. 18A, the difference between the outer radius RI and the inner radius R2 of the fan blade 832 is greater than or equal to 3 mm and less than or equal to 6 mm (i.e., 3 mm≤(R1−R2)≤6 mm). For example, the difference between the outer radius R1 and the inner radius R2 is equal to 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, or 6 mm. Here, the first curved surface 8321 of the fan blade 832 extends along an arc with a radius R1, and the second curved surface 8322 of the fan blade 832 extends along an arc with a radius R2, so that a difference between the radius of the first curved surface 8321 of the fan blade 832 and the radius of the second curved surface 8322 of the fan blade 832 is any value within a range of 3-6 mm.

In some embodiments, a circumference 801 where the first curved surface 8321 is located and a circumference 802 where the second curved surface 8322 is located are concentric circles, which facilitates production and processing.

In some embodiments, as shown in FIG. 17B and FIG. 17D, the third atomization member 83 further includes a plurality of atomization teeth 835. The plurality of atomization teeth 835 are arranged on the plurality of fan blades 832. Two or more atomization teeth 835 are arranged on at least one side of any one fan blade 832, and the two or more atomization teeth 835 are spaced apart from each other on the fan blade 832. The atomization teeth 835 on any one fan blade 832 may face corresponding second spray holes 833. For example, in a fan blade 832, the atomization teeth 835 are arranged on the second curved surface 8322 of the fan blade 832, and tooth tips of the plurality of atomization teeth 835 face the second spray holes 833. By arranging the atomization teeth 835, the amount of the condensate water lifted by the fan blade 832 may be increased, and the atomization effect of the fan blade on the condensate water may be improved.

In some examples, as shown in FIG. 17C, the portable air conditioner 1 further includes a pressure sensor 87. The pressure sensor 87 is arranged at the second spray hole 833 and configured to detect a water pressure in the second spray hole 833. For example, the pressure sensor 87 is arranged in the third atomization member 83. Thus, whether the pressure of the condensate water in the third atomization member 83 can drive the fan blade 832 to rotate fast may be determined, so that the spray effect of the third atomization member 83 is improved.

In some embodiments, as shown in FIG. 17A to FIG. 17C, the water-lifting assembly 30 further includes a water inlet pipe 85. The water inlet pipe 85 and the second rotary shaft 82 are coaxially arranged. For example, the second rotary shaft 82 is hollow inside, the water inlet pipe 85 is located in the second rotary shaft 82, and a central axis of the water inlet pipe 85 overlaps with a central axis of the second rotary shaft 82.

A first end of the water inlet pipe 85 is connected to the second water pump 84, and a second end of the water inlet pipe 85 is in communication with the plurality of second spray holes 833. For example, the water-lifting assembly 30 further includes a plurality of sub-water inlet pipes 86. First ends of the plurality of sub-water inlet pipes 86 are in communication with a second end of the water inlet pipe 85, and second ends of the plurality of sub-water inlet pipes 86 are in communication with the plurality of second spray holes 833, respectively. Thus, the condensate water from the second water pump 84 may be divided into a plurality of branch flows through the plurality of sub-water inlet pipes 86, and the plurality of branch flows flow into the plurality of second spray holes 833 and flow out from the plurality of second spray holes 833, respectively.

In some embodiments, the water-lifting assembly 30 further includes a filter. The filter is arranged between a water outlet of the second water pump 84 and a water inlet of the third atomization member 83 and is configured to filter impurities in the condensate water. The filter may include a filter screen, and the mesh number of the filter screen may be greater than or equal to 100 to improve the filter effect of the filter and prevent the impurities from blocking the second spray hole 833.

In some embodiments, start and stop of the second water pump 84 and the fourth driving member 81 are relevant to the water level in the water-collecting member 103 and the water pressure in the third atomization member 83, and the rotating speed of the fourth driving member 81 is relevant to the water level in the water-collecting member 103 and an exhaust temperature and an exhaust humidity.

Here, the exhaust temperature is a temperature of air after heat exchange with the first heat exchanger 101 and may be detected by a corresponding temperature sensor. The exhaust humidity is a humidity of air after heat exchange with the first heat exchanger 101 and may be detected by a corresponding humidity sensor. Moreover, the temperature sensor that detects the exhaust temperature and the humidity sensor that detects the exhaust humidity may be arranged at an exhaust pipe of the outdoor portion 10. The exhaust pipe is in communication with a first air outlet and an outdoor environment.

For example, the controller 60 is electrically connected to the second water pump 84 and the fourth driving member 81. As shown in FIG. 19, the controller 60 is configured to execute step 901 to step 910.

In step 901, whether the water level in the water-collecting member 103 is greater than or equal to the first preset water level is determined. If yes, step 902 is executed; otherwise, step 910 is executed.

After the portable air conditioner 1 starts, the condensate water generated during work of the portable air conditioner 1 flows into the water-collecting member 103, and the water level in the water-collecting member 103 rises. In this case, the controller 60 may determine whether the water level in the water-collecting member 103 is greater than or equal to the first preset water level by the water level sensor 90.

In step 902, the fourth driving member 81 is controlled to stop working, and the second water pump 84 is controlled to start.

In a case where the water level in the water-collecting member 103 is greater than or equal to the first preset water level, the controller 60 controls the fourth driving member 81 to stop working and controls the second water pump 84 to start. The second water pump 84 pumps the condensate water to the third atomization member 83, so that the condensate water is sprayed from the second spray hole 833. In this case, the third atomization member 83 may rotate.

In step 903, whether the pressure of the condensate water in the third atomization member 83 is less than the preset pressure is determined. If yes, step 904 is executed; otherwise, step 905 is executed.

In step 904, the second water pump 84 is controlled to stop working, and the fourth driving member 81 is controlled to start.

In step 905, the second water pump 84 is controlled to work continuously.

When the pressure of the condensate water in the third atomization member 83 is lower than the preset pressure, the water level in the water-collecting member 103 is less than the first preset water level, the amount of the condensate water in the water-collecting member 103 is decreased, so that it is not needed to pump water. Therefore, the second water pump 84 stops working, and the fourth driving member 81 starts.

In step 906, whether the exhaust temperature is less than the preset temperature or the exhaust humidity is greater than the preset humidity is determined. If yes, step 907 is executed; otherwise, step 908 is executed.

In step 907, the fourth driving member 81 is controlled to rotate at a first rotating speed.

In step 908, the fourth driving member 81 is controlled to rotate at a second rotating speed.

When the water level of the condensate water is less than the first preset water level and the exhaust temperature is lower than the preset temperature or the exhaust humidity is higher than the preset humidity, the controller 60 may control the fourth driving member 81 to rotate at the first rotating speed; otherwise, the controller 60 may control the fourth driving member 81 to rotate at the second rotating speed. The first rotating speed is less than the second rotating speed.

In any step above, the controller 60 is further configured to execute step 909.

In step 909, whether the water level in the water-collecting member 103 is greater than or equal to the second preset water level is determined. If yes, step 910 is executed; otherwise, step 901 is executed.

In step 910, the portable air conditioner 1 is controlled to stop.

If the water level in the water-collecting member 103 is higher than the second preset water level in the above process, the portable air conditioner 1 stops. Here, the second preset water level may be understood as the highest water level that can be reached by the condensate water in the water-collecting member 103. If the water level in the water-collecting member 103 is higher than the second preset water level, the condensate water spills over from the water-collecting member 103.
