The window air conditioner is provided with a mounting bracket during installation, and the mounting bracket can help to raise the height of the outer side of the window air conditioner so as to keep it level with the indoor unit. However, the traditional mounting brackets are generally large in size, high in production cost and transportation cost, and unattractive in appearance when exposed to outside of window air conditioners.

As shown in FIGS. 1, 2 and 3, a mounting bracket 100 for a window air conditioner 200 is provided according to some embodiments of the present disclosure. The mounting bracket 100 is configured to be disposed on at least one of a window sill and a window frame, and the mounting bracket 100 is configured to support the window air conditioner 200.

It should be noted that the window air conditioner 200 is usually installed at a window, and a part of the window air conditioner is located indoors and a part of the window air conditioner is located outdoors. The window sill of the window is generally provided with a window frame, and there is a height difference between the window frame and the window sill, which is not a flat plane. Directly installing the window air conditioner 200 will cause the indoor unit and the outdoor unit of the window air conditioner 200 to be unable to be on the same horizontal plane, which is extremely unstable and easy to shake. The mounting bracket 100 is installed on at least one of a window sill and a window frame, the base of the mounting bracket 100 is disposed on the window sill, and the window air conditioner 200 is installed on the mounting bracket 100, so that the window air conditioner 200 can be kept horizontal and stable, vibration and noise generated during operation can be reduced, and the comfort of the living environment can be improved.

In some embodiments, as shown in FIGS. 1, 2 and 3, at least two mounting brackets 100 may be provided. At least two mounting brackets 100 may be arranged on the window sill and/or the window frame at intervals. At least two mounting brackets 100 may be provided at intervals in the left-right direction (i.e., the length direction) of the window air conditioner 200. Since the window air conditioner 200 has a large weight, the window sill can be avoided from being deformed or damaged by providing at least two mounting brackets 100 to support the window air conditioner 200. The two mounting brackets 100 spaced apart in the left-right direction increase the support area of the mounting brackets 100 for the window air conditioner 200, can distribute the weight of the window air conditioner 200 evenly, reduces the localized pressure exerted by the window air conditioner 200 to the window sill structure, improves the stability and safety of the installation, and also mitigates the vibration and noise generated by the window air conditioner 200 during operation, thereby enhancing the comfort of the living environment.

It should be noted that in some other embodiments, the number of mounting brackets 100 may be three, four, or more depending on the weight of the window air conditioner 200 and the specific situation of the mounting environment. The heavier the window air conditioner 200 or the more unstable the installation environment, the more mounting brackets 100 are required.

In some other embodiments, the number of mounting brackets 100 may be one depending on the weight of the window air conditioner 200 and the specific situation of the mounting environment.

In some embodiments, as shown in FIGS. 4, 5 and 6, the mounting bracket 100 may include a support member 110. The support member 110 may extend in the front-rear direction (i.e. a length direction) of the window air conditioner 200. The support member 110 and the window air conditioner 200 are fixedly connected. The bottom surface of the window air conditioner 200 may be supported on the top surface of the support member 110.

In some embodiments, as shown in FIGS. 5, 7 and 8, the mounting bracket 100 may include a base 120. The base 120 may be disposed on the window sill. The base 120 may mate with the support member 110, and the support member 110 may be supported on the window sill by the base 120.

In some embodiments, as shown in FIGS. 8, 9 and 10, the mounting bracket 100 may include an adjustment member 130. The adjustment member 130 is configured to adjust the distance between the support member 110 and the base 120. The lower end of the adjustment member 130 may be fixedly connected to the base 120. A first adjustment portion 131 may be provided on the adjustment member 130. A second adjustment portion 111 may be provided on the support member 110. The first adjustment portion 131 may mate with the second adjustment portion 111, and may be configured to adjust the distance between the support member 110 and the surface of the window sill.

In some embodiments, as shown in FIGS. 6, 7 and 8, the support member 110 is a part that can be secured to the bottom of the window air conditioner 200. The support member 110 may be a plate-like structure. The support member 110 extends in the front-rear direction of the window air conditioner 200, and the surface of the support member 110 in contact with the bottom of the window air conditioner 200 is flat. The support member 110 is fitted to the bottom surface of the window air conditioner 200 to ensure stable support of the window air conditioner and minimize wobbling of the window air conditioner 200.

In some embodiments, the support member 110 may be sheet metal. The sheet metal is simple to form and has high strength, which can enhance the structural strength of the support member 110.

In some embodiments, as shown in FIGS. 3, 4 and 5, the dimension of the support member 110 in the front-rear direction may be smaller than the dimension of the window air conditioner 200 in the front-rear direction. That is, in the front-rear direction, the dimension of the support member 110 is smaller than the dimension of the window air conditioner 200. This allows for a more streamlined size of the mounting bracket 100 on the one hand, and on the other hand allows the support member 110 to not be exposed relative to the window air conditioner 200 in the front-rear direction, thereby making the support member 110 less likely to scratch the user.

In some embodiments, as shown in FIGS. 8, 9 and 10, the base 120 may be of a cylindrical structure. The base 120 of the cylindrical structure disposed on the window sill provides stable support for the support member 110 and the window air conditioner 200. The contact area between the base 120 of the cylindrical structure and the window sill is large, and the support area of the base 120 of the cylindrical structure is continuous and uniform, which can reduce the risk of deformation or damage to the window sill caused by excessive local pressure. The base 120 of the cylindrical structure is simple in structure, which is convenient for subsequent cleaning and maintenance, and helps to prolong the service life of the mounting bracket 100.

In some embodiments, the base 120 may be made of a plastic material, such as PC (Polycarbonate), ABS (Acrylonitrile Butadiene Styrene), or the like.

In some embodiments, as shown in FIGS. 8, 9 and 10, the adjustment member 130 may be disposed between the base 120 and the support member 110. The lower end of the adjustment member 130 may be fixedly connected to the base 120. The upper end of the adjustment member 130 can be movably connected to the second adjustment portion 111 of the support member 110 through the first adjustment portion 131. By the first adjustment portion 131 on the adjustment member 130 and the second adjustment portion 111 of the support member 110 mating with each other, the distance between the support member 110 and the base 120 can be adjusted, thereby adjusting the distance between the window air conditioner 200 and the window sill. In addition, the bottom of the window air conditioner 200 may be raised to a position flush with the window frame by the adjustment member 130. In this way, the indoor unit and the outdoor unit of the window air conditioner 200 can be located on the same horizontal plane, and can be stably installed on the window, thereby reducing vibration and noise generated during operation, further helping to improve the comfort of the living environment.

In some embodiments, as shown in FIGS. 8, 9 and 10, the adjustment member 130 may be a screw. The first adjustment portion 131 may have a threaded structure. The second adjustment portion 111 may be a screw hole, and the inner wall of the screw hole is provided with a screw thread. The mating of the first adjustment portion 131 and the second adjustment portion 111 may be a screw mating. By rotating the base 120, the base 120 drives the adjustment member 130 to move, and the screw rotation between the first adjustment portion 131 and the second adjustment portion 111 produces a spiral upward or downward movement, which drives the support member 110 to move up and down, thereby realizing the adjustment of the height of the window air conditioner 200.

Additionally, the mounting bracket 100 features a compact structure with a shorter length and a reduced footprint, leading to lower production and transportation costs, while also offering convenient storage. Moreover, the mounting bracket 100 is entirely located below the window air conditioner 200, which is relatively concealed, and can make the installed window air conditioner 200 aesthetically pleasing and streamlined appearance.

The compact mounting bracket 100 enables height adjustment of the window air conditioner 200 at a lower cost through the use of a compact design, ensures that the window air conditioner 200 can be stably installed on the window, reduces vibration and noise generated during operation, improves the comfort of the living environment, and the window air conditioner 200 installed with the mounting bracket 100 is aesthetically pleasing and streamlined appearance.

In some embodiments, as shown in FIGS. 8, 9 and 10, the base 120 may include a first base body 121. The adjustment member 130 may be provided on the first base body 121.

In some embodiments, as shown in FIGS. 8, 9 and 10, the base 120 may include a second base body 122. The second base body 122 and the first base body 121 may be snap-fitted to each other. The second base body 122 may be disposed on the window sill. The base 120 may be composed of two parts: the first base body 121 and the second base body 122. The first base body 121 may be located above the second base body 122 and partially within the second base body 122. The first base body 121 and the second base body 122 are snap-fitted to each other to form a stable structure for supporting the weight of the support member 110 and the window air conditioner 200.

When the base 120 rotates, the support member 110 and the adjustment member 130 move relative to each other. Since the adjustment member 130 is fixed on the first base body 121, the first base body 121 and the second base body 122 are snap-fitted, the second base body 122 is arranged on the window sill, and the second base body 122 is fixed on the window sill by the action of gravity of the window air conditioner 200 above. Consequently, the support member 110 moves vertically, altering the distance between the support member 110 and the base 120, thereby achieving height adjustment of the window air conditioner 200.

In some embodiments, as shown in FIGS. 9, 10 and 11, the outer periphery of the first base body 121 may be provided with a first limiting portion 1211. A second limiting portion 1221 may be provided on the inner wall of the second base body 122. The first limiting portion 1211 and the second limiting portion 1221 are in limiting fit with each other, allowing the second base body 122 and the first base body 121 to be snap-fitted to each other, and preventing the first base body 121 from moving relatively in the circumferential direction in the second base body 122.

In some embodiments, as shown in FIGS. 9, 10 and 11, the first limiting portion 1211 may be a raised portion located on the outer periphery of the first base body 121. The second limiting portion 1221 may be a recessed portion located on the inner wall of the second base body 122. The raised portion and the recessed portion correspond to each other. When the first base body 121 and the second base body 122 are snapped together, the raised portion can be embedded in the recessed portion so that both sides of the raised portion are blocked. As a result, the first base body 121 cannot move relatively in the circumferential direction in the second base body 122. When the operator rotates the second base body 122, the first base body 121 can rotate along with the second base body 122, which drives the adjustment member 130 to rotate relative to the support member 110, thereby realizing the adjustment of the height of the window air conditioner 200.

In some embodiments, as shown in FIGS. 9, 10 and 11, an accommodating groove 1212 may be provided at the side of the first base body 121 facing the second base body 122. A third limiting portion 1222 may be provided on the bottom wall of the second base body 122. The third limiting portion 1222 may be a boss structure protruding from the bottom wall of the second base body 122. The third limiting portion 1222 may be in limiting fit with the accommodating groove 1212. The lower end of the adjustment member 130 may be abutted with h the third limiting portion 1222.

For example, the accommodation groove 1212 is disposed below the first base body 121 for accommodating the third limiting portion 1222 of the second base body 122. The third limiting portion 1222 of the second base body 122 may be located at a central region of the bottom wall of the second base body 122, while the space for accommodating the side wall of the first base body 121 is left at inner side of the edge of the bottom wall of the second base body 122. When the first base body 121 and the second base body 122 are snap-fitted into each other, the side wall of the first base body 121 can be snap-fitted with inner side of the edge of the bottom wall of the second base body 122, thereby restricting the relative positions of the first base body 121 and the second base body 122, ensuring that the first base body 121 and the second base body 122 are tightly snapped into each other, and improving the reliability of the mounting bracket 100.

In some embodiments, as shown in FIG. 12, the dimension of the support member 110 in the left-right direction of the window air conditioner 200 may be h1. The dimension of the base 120 in the left-right direction of the window air conditioner 200 may be h2. h2 and h1 may satisfy the relation: h2>h1. As described above, the dimension of the base 120 in the left-right direction of the window air conditioner 200 is greater than the dimension of the support member 110 in the left-right direction of the window air conditioner 200, that is, the width of the base 120 is greater than the maximum width of the support member 110. In this way, the base 120 can be made to protrude from both sides of the support member 110 in the left-right direction of the window air conditioner 200. When mounting the mounting bracket 100, the operator can come into contact with a part of the base 120 exposed outside the support member 110, thereby improving the convenience of operation of the mounting bracket 100 and improving the operability of the mounting bracket 100.

In some embodiments, as shown in FIGS. 8 and 12, a plurality of the second adjustment portions 111 on the support member 110 may be provided. The plurality of second adjustment portions 111 may be provided at intervals in the front-rear direction of the window air conditioner 200. The first adjustment portion 131 may be mated with any one of the second adjustment portions 111. For example, in some embodiments of the present disclosure, there are four second adjustment portions 111 on the support member 110.

It should be noted that in some other embodiments, the number of second adjustment portions 111 on the support member 110 may also be two, three, five, or more. Since the plurality of second adjustment portions 111 are provided, the adjustment effect of the window air conditioner 200 is different depending on the position of the second adjustment portions 111. According to the installation situation of the window air conditioner 200, the first adjustment portion 131 can be optionally mated and connected to any one of the second adjustment portions 111, so that the practicality of the mounting bracket 100 is improved and the operation is more flexible.

In some embodiments, as shown in FIGS. 6, 7 and 8, a clearance groove 112 is provided on the upper surface of the support member 110. One or more second adjustment portions 111 may be provided in the clearance groove 112. The upper end of the adjustment member 130 may not exceed the upper end of the clearance groove 112. The position of the second adjustment portion 111 may be lower than the contact surface of the support member 110 with the bottom surface of the window air conditioner 200. By providing the clearance groove 112, a space can be left between the second adjustment portion 111 and the bottom of the window air conditioner 200, to prevent the adjustment member 130 from touching the bottom of the window air conditioner 200 as it exceeds the upper end of the clearance groove 112, thereby preventing the contact surface of the window air conditioner 200 with the support member 110 from being uneven and affecting the stability of the installation.

In some embodiments, as shown in FIGS. 6, 7 and 8, the support member 110 may include a support portion 113. The support portion 113 and the adjustment member 130 may be mated with each other. The second adjustment portion 111 on the support portion 113 can mate with the adjustment member 130 to adjust the height of the window air conditioner 200.

In some embodiments, as shown in FIGS. 5, 6, 7 and 8, the support member 110 may include a fixed portion 114. The fixed portion 114 and the support portion 113 may be provided at intervals in the front-rear direction of the window air conditioner 200. The fixed portion 114 may be fixedly connected to the window air conditioner 200, and the fixed portion 114 may be fixedly connected to the window frame. The fixed portion 114 is configured to be fixedly connected to the bottom of the window air conditioner 200 and the window frame, so that the mounting bracket 100, the window air conditioner 200 and the window frame can be fixed together, and the mounting stability can be improved.

In some embodiments, as shown in FIGS. 5, 6, 7 and 8, a portion of the support member 110 near the front end in the front-rear direction of the window air conditioner 200 may be the fixed portion 114, and a portion of the support member 110 near the rear end may be the support portion 113. The fixed portion 114 may be connected to the front end of the support portion 113.

In some embodiments, as shown in FIGS. 5, 6, 7 and 8, a first mounting portion 1141 may be provided on the fixed portion 114. The first mounting portion 1141 may be configured to be fixedly connected to the window air conditioner 200. For example, the first mounting portion 1141 may be a mounting hole. The first mounting portion 1141 and the window air conditioner 200 may be connected by bolts. There may be a plurality of first mounting portions 1141, and the plurality of first mounting portions 1141 may be distributed at intervals on the fixed portion 114, thereby ensuring that the support member 110 and the window air conditioner 200 are firmly connected.

In some embodiments, as shown in FIGS. 5, 6, 7 and 8, the fixed portion 114 may be provided with a mounting flange 1142 that folds toward the lower side. The mounting flange 1142 may be provided at one end of the fixed portion 114 away from the support portion 113. The mounting flange 1142 may be provided with a second mounting portion 1143. The second mounting portion 1143 may be configured to be fixedly connected to the window frame. The mounting flange 1142 may correspond to the position of the window frame. The second mounting portion 1143 on the mounting flange 1142 may be a mounting hole, and the second mounting portion 1143 and the window frame may be connected by bolts. At least two second mounting portions 1143 may be provided, and the at least two second mounting portions 1143 may ensure that the support member 110 and the window frame are firmly connected.

According to another aspect, as shown in FIGS. 1, 2, 3 and 6, some embodiments of the present disclosure also provide a window air conditioner assembly that may include the window air conditioner 200 and the mounting bracket 100. The window air conditioner 200 may be carried on the mounting bracket 100. The mounting bracket 100 may be disposed on the window sill. The window air conditioner 200 may be supported on the window frame and the mounting bracket 100 at the same time. The compact mounting bracket 100 enables height adjustment of the window air conditioner 200 at a lower cost through the use of a compact design, ensures that the window air conditioner 200 can be stably installed on the window, reduces vibration and noise generated during operation, improves the comfort of the living environment, and the window air conditioner 200 installed with the mounting bracket 100 is aesthetically pleasing and streamlined appearance.

In some embodiments, as shown in FIGS. 1 and 2, the window air conditioner 200 includes an indoor unit 201 and an outdoor unit 202. The indoor unit 201 and the outdoor unit 202 may be connected by a pipeline to deliver a refrigerant.

In some embodiments, the indoor unit 201 may include an indoor heat exchanger and an indoor fan.

In some embodiments, the outdoor unit 202 may include a compressor, a four-way valve, an outdoor heat exchanger, an outdoor fan, and an expansion valve. The compressor, the outdoor heat exchanger, the expansion valve and the indoor heat exchanger are sequentially connected to form a refrigerant circuit. The refrigerant can circulate in the refrigerant circuit, and exchange heat with indoor and outdoor air through the outdoor heat exchanger and the indoor heat exchanger, respectively, so as to realize the cooling mode or the heating mode of the window air conditioner 200.

In some embodiments, the outdoor heat exchanger may be configured to transfer heat between outdoor air and refrigerant circulating through the outdoor heat exchanger. For example, the outdoor heat exchanger operates as a condenser in the cooling mode of the window air conditioner 200, so that the refrigerant compressed by the compressor is condensed by dissipating heat to the outdoor air through the outdoor heat exchanger. The outdoor heat exchanger operates as an evaporator in the heating mode of the window air conditioner 200, so that the refrigerant after decompression absorbs the heat of the outdoor air through the outdoor heat exchanger and evaporates.

In some embodiments, the outdoor fan may be configured to draw outdoor air into the outdoor unit 202 through an outdoor air inlet of the outdoor unit 202 and expel the outdoor air after heat exchange with an outdoor heat exchanger through an outdoor air outlet of the outdoor unit 202. The outdoor fan provides power for the flow of outdoor air.

In some embodiments, the indoor heat exchanger may be configured to exchange heat between indoor air and the refrigerant circulating within the indoor heat exchanger. For example, in the cooling mode of the window air conditioner 200, the indoor heat exchanger operates as an evaporator, allowing the refrigerant that has cooled in the outdoor heat exchanger to absorb heat from indoor air as it evaporates when passing through the indoor heat exchanger. In the heating mode of the window air conditioner 200, the indoor heat exchanger operates as a condenser, allowing the refrigerant that has heated in the outdoor heat exchanger to dissipate heat to the indoor air as it condenses when passing through the indoor heat exchanger.

In some embodiments, when the window air conditioner 200 operates in cooling mode, the discharge port of the compressor communicates with the outdoor heat exchanger, which functions as a condenser. Outdoor air entering through the outdoor air inlet flows to the outdoor heat exchanger, where the refrigerant releases a significant amount of heat. The outdoor air absorbs the heat from the refrigerant.

In some embodiments, when the window air conditioner 200 operates in heating mode, the discharge port of the compressor communicates with the indoor heat exchanger, while the outdoor heat exchanger functions as an evaporator. After releasing heat at the indoor heat exchanger, the refrigerant flows to the outdoor heat exchanger. Outdoor air entering through the outdoor air inlet is directed to the outdoor heat exchanger, where the refrigerant absorbs heat from the outdoor air.

In some embodiments, the indoor fan is configured to draw indoor air into the indoor unit 201 through a third air inlet of the indoor unit 201 and expel the indoor air after heat exchange with the indoor heat exchanger through a fourth air outlet of the indoor unit 201. The indoor fan provides power for the flow of air in the indoor space.

In some embodiments, the window air conditioner 200 may include a control device. The control device can be configured to control the operating frequency of the compressor, the opening of the expansion valve, the rotational speed of the outdoor fan and the rotational speed of the indoor fan, respectively. The control device may be connected to the compressor, the expansion valve, the outdoor fan and the indoor fan through data lines to transmit communication information.

In some embodiments, as shown in FIGS. 13 and 14, the window air conditioner 200 may include an indoor heat exchanger 24. The indoor heat exchanger 24 may be configured to exchange heat with the indoor air.

In some embodiments, as shown in FIGS. 13 and 14, the window air conditioner 200 may include an indoor fan assembly 25. The indoor fan assembly 25 transmits the indoor air to the indoor heat exchanger 24 for heat exchange and then outputs the indoor air to the indoor, thereby adjusting the indoor temperature.

In some embodiments, as shown in FIGS. 13 and 14, the indoor housing 20 may be configured to house the indoor heat exchanger 24 and the indoor fan assembly 25. An indoor chamber 23 may be formed between the indoor housing 20 and the chassis 210. The indoor chamber 23 is provided with the indoor heat exchanger 24 and the indoor fan assembly 25. In this way, the indoor chamber 23 can provide an installation space for the indoor heat exchanger 24 and the indoor fan assembly 25, and can also facilitate the formation of an indoor air duct, thereby facilitating heat exchange and air supply to the indoor.

In addition, the indoor heat exchanger 24 is provided in the indoor chamber 23, and the indoor chamber 23 can not only protect the indoor heat exchanger 24, but also prevent dust from falling into the indoor heat exchanger 24, which affects the heat exchange efficiency of the heat exchanger, and also prevents the indoor heat exchanger 24 from being subjected to an external force, which may cause damage.

In some embodiments, as shown in FIGS. 13 and 14, the indoor fan assembly 25 is disposed in the indoor chamber 23, and the indoor fan assembly 25 may be positioned above the indoor heat exchanger 24.

In some embodiments, the indoor fan assembly 25 may include an axial flow fan. The axial flow fan can draw in air for cold and heat exchange, and send it out through the indoor heat exchanger 24, thereby regulating the indoor temperature. The axial flow fan has high-efficiency air flow characteristics, enabling effective propulsion of air circulation, which enhances the overall performance of the window air conditioner 200.

In some embodiments, as shown in FIGS. 13 and 14, the window air conditioner 200 may include an outdoor heat exchanger 32. The outdoor heat exchanger 32 may be configured to exchange heat with outdoor air.

In some embodiments, as shown in FIGS. 13 and 14, the window air conditioner 200 may include an outdoor fan assembly 33. The outdoor fan assembly 33 can convey outdoor air to the outdoor heat exchanger 32 for heat exchange and then output it to the outdoor, thereby regulating the outdoor temperature.

In some embodiments, the outdoor fan assembly 33 includes a motor and an outdoor fan, and the motor drives the outdoor fan to rotate, which can deliver the outdoor air to the outdoor heat exchanger 32 for heat exchange and then output to the outdoor, so that the outdoor temperature can be regulated.

In some embodiments, as shown in FIGS. 13 and 14, the outdoor housing 30 may be configured to house the outdoor heat exchanger 32 and the outdoor fan assembly 33. An outdoor chamber 31 may be formed between the outdoor housing 30, a rear side of the indoor housing 20 and the chassis 210. The outdoor heat exchanger 32 is disposed in the outdoor chamber 31, and the outdoor fan assembly 33 is disposed in the outdoor chamber 31, and the outdoor chamber 31 can provide an installation space for the outdoor heat exchanger 32 and the outdoor fan assembly 33.

In some embodiments, as shown in FIGS. 13 and 14, the outdoor housing 30 may be spaced from the indoor housing 20, thereby allowing adjustment of the distance of the outdoor chamber 31 in the front-rear direction. The chassis 210 corresponding to the outdoor housing 30 can provide mounting and supporting functions for the outdoor heat exchanger 32 and the outdoor fan assembly 33.

In some embodiments, as shown in FIGS. 14, 16 and 18, the window air conditioner 200 may include a water collection tray 40. The water collection tray 40 may be provided in the indoor chamber 23. The water collection tray 40 may be located below the indoor heat exchanger 24. In this way, the water collection tray 40 can facilitate collecting the condensed water generated by the indoor heat exchanger 24, thereby avoiding the outflow of the condensed water, and also improving the safety of the internal circuit of the window air conditioner 200.

In some embodiments, as shown in FIGS. 16, 17, 18 and 19, the water collection tray 40 may have a drainage channel 41 extending into the outdoor chamber 31. By providing the drainage channel 41, it is possible not only to collect the condensed water but also to drain water, so that the condensed water generated by the indoor heat exchanger 24 can flow to the outdoor chamber 31 through the drainage channel 41 on the water collection tray 40.

In some embodiments, as shown in FIGS. 13 and 18, the indoor housing 20 may include a front housing 21. The front housing 21 is provided on the chassis 210. The front housing 21 may be provided with an indoor air inlet 211 and an indoor air outlet 212. The indoor air inlet 211 and the indoor air outlet 212 communicate with the indoor chamber 23, respectively. In this way, it is possible to facilitate the indoor air to enter the indoor chamber 23 through the indoor air inlet 211, exchange heat with the indoor heat exchanger 24, and then flow out from the indoor air outlet 212, thereby adjusting the indoor temperature.

In some embodiments, as shown in FIGS. 13 and 18, the indoor housing 20 may include a rear housing 22. The rear housing 22 may be provided on the chassis 210. The rear housing 22 may be connected to the front housing 21, and thereby forming an indoor chamber 23 between the rear housing 22 and the front housing 21.

In some embodiments, as shown in FIGS. 18, 24, 25 and 26, an outdoor fan assembly 33 may be disposed within the outdoor chamber 31. The motor and the outdoor fan in the outdoor fan assembly 33 generate noise during operation. A compressor 34 may be provided in the outdoor chamber 31. The compressor 34 also produces noise during operation. The noise generated by the outdoor fan assembly 33 and the compressor 34 can be transmitted through the air, and the rear housing 22 can separate the outdoor chamber 31 and the indoor chamber 23, thereby playing the role of soundproofing.

In some embodiments, as shown in FIGS. 18, 24, 25 and 26, the rear housing 22 may be formed with a clearance hole 221. A portion of the drainage channel 41 in the water collection tray 40 may extend to the outdoor chamber 31 through the clearance hole 221. In this way, part of the noise generated in the outdoor chamber 31 is directly transmitted to the indoor chamber 23 through the gap generated by the drainage channel 41 of the water collection tray 40 and the clearance hole 221.

In some embodiments, as shown in FIGS. 14 and 18, the rear housing 22 may be provided with a first soundproofing structure 50 proximate to the drainage channel 41. The first soundproofing structure 50 can prevent noise generated in the outdoor chamber 31 from being transmitted to the indoor chamber 23 through the drainage channel 41.

In some embodiments, soundproofing cotton may be provided on the rear housing 22 of the indoor housing 20. The soundproofing cotton can further play the role of soundproofing, which can further play the role of noise reduction.

In some embodiments, as shown in FIGS. 15, 16 and 17, the first soundproofing structure 50 is provided at the side of the rear housing 22 facing the outdoor chamber 31. The first soundproofing structure 50 may cover a portion of the drainage channel 41. A portion of the drainage channel 41 includes a water outlet 90. The first soundproofing structure 50 may cover the drainage channel 41 including the water outlet 90.

When the noise of the outdoor chamber 31 is transmitted to the drainage channel 41, the noise propagates in the air in the form of sound waves. When the noise encounters the first soundproofing structure 50, the noise is reflected under the blocking of the first soundproofing structure 50, thereby preventing the noise of the outdoor chamber 31 from being transmitted to the indoor chamber 23. This reduces the noise transmitted into the drainage channel 41 while also improving the sound insulation capacity at the drainage channel 41.

As a result, the first soundproofing structure 50 in the window air conditioner 200 can reflect the noise generated by the compressor 34 and the outdoor fan assembly 33 in the outdoor chamber 31 back through the blocking of the first soundproofing structure 50, which can prevent the noise of the outdoor chamber 31 from being transmitted to the indoor chamber 23, thereby reducing the noise transmitted to the drainage channel 41, and also improving the sound insulation capacity at the drainage channel 41.

According to some embodiments of the present disclosure, as shown in FIGS. 15 and 17, the first soundproofing structure 50 may be configured as a soundproofing cover with an open bottom. The soundproofing cover can serve as an enclosing structure, wrapping around the portion of the drainage channel 41 that includes the water outlet 90. This can effectively block noise from entering from different directions outside the soundproofing cover. Furthermore, the arrangement of the open bottom of the soundproofing cover allows for drainage of condensed water, prevents its blocking, and thereby avoids pooling of condensed water.

In some embodiments, as shown in FIGS. 17 and 19, a first soundproofing chamber 54 in communication with the clearance hole 221 may be formed in the first soundproofing structure 50. The first soundproofing chamber 54 is configured to provide energy absorption and noise reduction. A portion of the drainage channel 41 is positioned within the first soundproofing chamber 54, thereby blocking noise from the outdoor chamber 31 from entering the indoor chamber 23 through that portion of the drainage channel 41 at the source. The noise in the first soundproofing chamber 54 may be reflected multiple times, thereby reducing transmission of the noise.

In some embodiments, as shown in FIGS. 15 and 25, the first soundproofing structure 50 may include a top plate 51. The top plate 51 may be connected to the rear housing 22. The top plate 51 is connected horizontally to the rear shell 22, where “horizontally” refers to the front-rear direction. The top plate 51 may be positioned on top of the first soundproofing chamber 54.

In some embodiments, as shown in FIGS. 15 and 25, the first soundproofing structure 50 may include a first side plate 52. Two first side plates 52 may be provided. The two first side plates 52 may be vertically connected to opposite sides of the top plate 51, where “vertically” refers to the vertical direction. The two first side plates 52 are connected to the rear housing 22, respectively. The two first side plates 52 may be located on the left and right sides of the first soundproofing chamber 54, respectively.

In some embodiments, as shown in FIGS. 15 and 25, the first soundproofing structure 50 may include a rear plate 53. The rear plate 53 may be connected to the top plate 51 and the first side plate 52, respectively. In this way, the top plate 51, the two first side plates 52, and the rear plate 53 may be enclosed together to form the first soundproofing chamber 54. The portion of the drainage channel 41 including the water outlet 90 may be located in the first soundproofing chamber 54, and noise at the outdoor chamber 31 may be prevented from entering the indoor chamber 23 through the drainage channel 41 including the water outlet 90.

Please note that the noise in the outdoor chamber 31 first passes through the rear plate 53, and the rear plate 53 can reflect most of the noise in the outdoor chamber 31 for the first time. Then, part of the noise transmitted to the rear plate 53 is reflected multiple times through the top plate 51 and the two first side plates 52 in the first soundproofing chamber 54, which can attenuate the noise again, so that the noise transmitted into the first soundproofing chamber 54 can be further reduced.

In some embodiments, as shown in FIGS. 15 and 17, the rear plate 53 may be disposed opposite the clearance hole 221. A portion of the drainage channel 41 passes through the clearance hole 221 and enters the first soundproofing chamber 54. Since the rear plate 53 is provided opposite to the clearance hole 221, it is possible to ensure an accurate mounting position between the rear plate 53 and a portion of the drainage channel 41, and thus it is possible to prevent the portion of the drainage channel 41 including the water outlet 90 from interfering with the rear plate 53.

In some embodiments, as shown in FIGS. 15 and 17, a portion of the chassis 210 corresponding to the outdoor chamber 31 is formed with a water storage tank 80 and a water diversion channel 70 that are in fluid communication. A portion of the drainage channel 41 may communicate with the water diversion channel 70. The water outlet 90 of the drainage channel 41 may communicate with the water storage tank 80 through the water diversion channel 70. In this way, the condensed water generated by the indoor heat exchanger 24 can flow to the water diversion channel 70 through the water outlet 90 of the drainage channel 41, and the water diversion channel 70 can function as a guide, so that the condensed water can be accurately discharged into the water storage tank 80.

In some embodiments, as shown in FIGS. 15 and 17, the two first side plates 52 may be located on both sides in the width direction of the water diversion channel 70, respectively. Two first side plates 52 may be provided, and the two first side plates 52 are disposed opposite each other. One of the first side plates 52 is located on one side of the water guide channel 70 in the width direction, and the other of the first side plates 52 is located on the other side of the water guide channel 70 in the width direction. In this way, the two first side plates 52 and the top plate 51 can cover a portion of the drainage channel 41, so that noise at the outdoor chamber 31 can be prevented from entering the first soundproofing chamber 54 from different directions around the first soundproofing structure 50.

In some embodiments, as shown in FIG. 17, the lower edge of the first soundproofing structure 50 is in contact with the upper surface of the chassis 210. The upper surface of the chassis 210 is a surface of the chassis 210 away from the water diversion channel 70, and the lower edge of the soundproofing cover is closely attached to the upper surface of the chassis 210.

For example, a tight contact fit of the bottoms of the two first side plates 52 with the upper surface of the chassis 210 prevents a gap from being formed between the bottoms of the first side plates 52 and the upper surface of the chassis 210, which prevents the transmission of the noise of the outdoor chamber 31 to the first soundproofing chamber 54 from the gap formed between the first side plates 52 and the upper surface of the chassis 210.

Further, the tight contact fit of the bottom of the rear plate 53 with the upper surface of the chassis 210 can also prevent a gap from being formed between the bottom of the rear plate 53 and the upper surface of the chassis 210, which prevents the transmission of the noise of the outdoor chamber 31 to the first soundproofing chamber 54 from the gap formed between the rear plate 53 and the upper surface of the chassis 210.

According to the window air conditioner 200 in some embodiments of the present disclosure, the window air conditioner 200 may include the chassis 210, the indoor housing 20, the outdoor housing 30, and the water collection tray 40. The indoor housing 20 is disposed on the chassis 210, and the indoor housing 20 and the chassis 210 form an indoor chamber 23. An indoor heat exchanger 24 is provided in the indoor chamber 23. The outdoor housing 30 is disposed on a chassis 210, and the outdoor housing 30, the rear side of the indoor housing 20, and the chassis 210 together form an outdoor chamber 31. The water collection tray 40 is provided in the indoor chamber 23 and is located below the indoor heat exchanger 24. The water collection tray 40 has a drainage channel 41 extending into the outdoor chamber 31. The indoor housing 20 includes a front housing 21 and a rear housing 22. The front housing 21 is provided with an indoor air inlet 211 and an indoor air outlet 212. The rear housing 22 is provided above the chassis 210 and connected to the front housing 21, and the rear housing 22 is formed with the clearance hole 221. A portion of the drainage channel 41 extends to the outdoor chamber 31 through the clearance hole 221. The first soundproofing structure 50 is provided on the side of the rear housing 22 facing the outdoor chamber 31. The first soundproofing structure 50 covers a portion of the drainage channel 41.

As a result, the first soundproofing structure 50 in the window air conditioner 200 can reflect the noise generated by the compressor 34 and the outdoor fan assembly 33 in the outdoor chamber 31 back through the blocking, which can prevent the noise of the outdoor chamber 31 from being transmitted to the indoor chamber 23, thereby reducing the noise transmitted to the drainage channel 41, and also improving the sound insulation capacity at the drainage channel 41.

In some embodiments, as shown in FIGS. 19, 20 and 21, the water collection tray 40 may be provided with a second soundproofing structure 60. The second soundproofing structure 60 may be located in the indoor chamber 23. The second soundproofing structure 60 may be located on the outer periphery of the drainage channel 41. The portion of the drainage channel 41 passes through the clearance hole 221, so that a gap is formed between a portion of the drainage channel 41 and the clearance hole 221. The second soundproofing structure 60 may be provided on the outer periphery of the water collection tray 40 close to the clearance hole 221, so that the second soundproofing structure 60 can seal the gap between the portion of the drainage channel 41 and the clearance hole 221, and further can prevent the remaining noise absorbed by the first soundproofing chamber 54 from being transmitted to the indoor chamber 23 through the gap between the portion of the drainage channel 41 and the clearance hole 221.

In some embodiments, as shown in FIGS. 19, 20 and 21, the second soundproofing structure 60 is located in the indoor chamber 23. In this way, the second soundproofing structure 60 may seal the clearance hole 221 at the indoor chamber 23. Since the second soundproofing structure 60 is located at the outer periphery of the drainage channel 41, the clearance hole 221 is opened in a square shape, and the second soundproofing structure 60 is provided around the outer periphery of the drainage channel 41. In this way, the edge of the clearance hole 221 can be covered, so that noise in the first soundproofing chamber 54 can be prevented from being transmitted to the indoor chamber 23 through the gap formed between the clearance hole 221 and the portion of the drainage channel 41.

In some embodiments, as shown in FIGS. 19, 20 and 21, the second soundproofing structure 60 may be configured as a soundproofing cover with open bottom and rear side. A second soundproofing chamber 623 may be formed in the second soundproofing structure 60. The portion of the drainage channel 41 in the indoor chamber 23 is located in the second soundproof chamber 623. The arrangement of the open bottom of the second soundproofing structure 60 can facilitate the formation of the second soundproof chamber 623 on the bottom of the second soundproofing structure 60 and the upper surface of the chassis 210. The arrangement of the open rear side of the second soundproofing structure 60 can facilitate the portion of the drainage channel 41 that includes the water outlet 90 to protrude from the open rear side of the second soundproofing structure 60.

In some embodiments, as shown in FIGS. 19, 20 and 21, the portion of the drainage channel 41 in the indoor chamber 23 is located in the second soundproofing chamber 623. When the noise in the first soundproofing chamber 54 is transmitted into the second soundproofing chamber 623 through the gap formed between the clearance hole 221 and the portion of the drainage channel 41, the second soundproofing chamber 623 can serve to perform secondary noise reduction. The second soundproofing chamber 623 reflects the residual noise again, thereby further enhancing the noise reduction effect.

In some embodiments, the second soundproofing chamber 623 may close the outer peripheral edge of the clearance hole 221, so that the second soundproofing chamber 623 may be formed as a sealed chamber, thereby blocking the residual noise of the first soundproofing chamber 54 from being transmitted to the indoor chamber 23.

In some embodiments, since the indoor fan assembly 25 is disposed in the indoor chamber 23, the indoor fan assembly 25 also generates noise during operation, and the second soundproofing chamber 623 is disposed in the indoor chamber 23, which can block the noise formed by the indoor fan assembly 25 in the indoor chamber 23 from being transmitted to the first soundproofing chamber 54 through the gap at the clearance hole 221.

It should be noted that, in some other embodiments, a third soundproofing chamber or a third soundproofing structure may be provided on the side of the clearance hole 221 located inside the first soundproofing chamber 54. The third soundproofing chamber or the third soundproofing structure can close the gap formed between the clearance hole 221 and the portion of the drainage channel 41, so that noise in the first soundproofing chamber 54 can be blocked from flowing to the second soundproofing chamber 623 through the gap. In this way, the gaps formed on both sides of the clearance hole 221 can be sealed, thereby achieving the effect of double sealing at the clearance hole 221.

In some embodiments, as shown in FIGS. 19, 20 and 21, the second soundproofing structure 60 may include a front plate 621. The front plate 621 may be connected to the bottom of the drainage channel 41. The top of the front plate 621 may be connected to the bottom of the drainage channel 41, and the front plate 621 may extend downwards. In this way, the noise in the second soundproofing chamber 623 can be reflected by the front plate 621, thereby blocking the noise in the second soundproofing chamber 623 from being transmitted to the indoor chamber 23.

In some embodiments, as shown in FIGS. 19, 20 and 21, the second soundproofing structure 60 may include a second side plate 622. Two second side plates 622 may be provided. The two second side plates 622 are disposed opposite each other. The two second side plates 622 may be connected to opposite sides of the front plate 621, respectively. The two second side plates 622 may be in contact with the rear housing 22, respectively.

In some embodiments, as shown in FIGS. 19, 20 and 21, the second soundproofing structure 60 may include a top cover plate 624. The top cover plate 624 is provided on the top of the second side plate 622. The top cover plate 624 may extend from the top of the second side plate 622 toward the drainage channel 41. In this way, when the second side plate 622 comes into contact with the rear housing 22, the top cover plate 624 and the second side plate 622 can respectively close the upper portion and the middle portion of the edge of the clearance hole 221, so that noise can be prevented from being transmitted from the upper portion and the middle portion of the edge of the clearance hole 221.

In some embodiments, as shown in FIGS. 21, 22 and 23, the lower edge of the second soundproofing structure 60 is in contact with the upper surface of the chassis 210. For example, the lower edge of the front plate 621 in the second soundproofing structure 60 may be closely fitted to the upper surface of the chassis 210, so that noise in the second soundproofing chamber 623 may be prevented from being transmitted from the lower edge of the front plate 621 to the indoor chamber 23.

For another example, the lower edge of the second side plate 622 may be closely fitted to the upper surface of the chassis 210, so that noise in the second soundproof chamber 623 may be prevented from being transmitted from the lower edge of the second side plate 622 to the indoor chamber 23.

According to the window air conditioner 200 provided by some embodiments of the present disclosure, as shown in FIGS. 13 and 14, the window air conditioner 200 may include the chassis 210, the indoor housing 20, the outdoor housing 30, the indoor heat exchanger 24, the indoor fan assembly 25, the outdoor fan assembly 33, and the water collection tray 40. The indoor housing 20 may be disposed on the chassis 210, the indoor housing 20 may form an indoor chamber 23 with the chassis 210, and the indoor heat exchanger 24 and the indoor fan assembly 25 are installed in the indoor chamber 23. The indoor fan assembly 25 delivers the indoor air to the indoor heat exchanger 24 for heat exchange and then outputs the indoor air to the indoor, thereby adjusting the temperature of the indoor air. The outdoor housing 30 may be disposed on a chassis 210, and the outdoor housing 30, the rear side of the indoor housing 20, and the chassis 210 together form the outdoor chamber 31. Thus, the outdoor housing 30, the area formed by connection between the chassis 210 and the outdoor housing 30, and the back plate of the indoor housing 20 can enclose to form the outdoor chamber 31, so that the outdoor chamber 31 can form an independent sealed area. When the compressor 34 and the outdoor fan assembly 33 in the outdoor chamber 31 generate noise, since the outdoor chamber 31 is a sealed area, the noise at the outdoor chamber 31 can be prevented from being transmitted to the indoor chamber 23.

In some embodiments, the water collection tray 40 is disposed in the indoor chamber 23, and the water collection tray 40 is located below the indoor heat exchanger 24, which can facilitate collection of condensed water generated by the indoor heat exchanger 24, thereby avoiding overflow of condensed water.

In some embodiments, as shown in FIGS. 14 and 17, the water collection tray 40 has a drainage channel 41 extending into the outdoor chamber 31. By providing the drainage channel 41, the condensed water of the water collection tray 40 can be discharged from the outdoor chamber 31, so that the accumulation of the condensed water at the water collection tray 40 can be avoided.

In some embodiments, as shown in FIGS. 13 and 14, the outdoor heat exchanger 32 is provided in the outdoor chamber 31, the outdoor fan assembly 33 is provided in the outdoor chamber 31, and the outdoor fan assembly 33 transmits outdoor air to the outdoor heat exchanger 32 for heat exchange and then outputs it to the outdoor.

In some embodiments, as shown in FIGS. 14 and 17, the indoor housing 20 is formed with the clearance hole 221. A portion of the drainage channel 41 extends to the outdoor chamber 31 through the clearance hole 221, and it is possible to facilitate the portion of the drainage channel 41 of the water collection tray 40 to pass through the clearance hole 221, so that it is possible to facilitate drainage of the condensed water of the water collection tray 40 to the outdoor chamber 31 and then discharge from the outdoor chamber 31.

In some embodiments, as shown in FIGS. 14 and 17, the window air conditioner 200 may include the first soundproofing structure 50. The first soundproofing structure 50 covers a portion of the drainage channel 41, and the first soundproofing structure 50 covering the portion of the drainage channel 41 can reflect noise transmitted to the first soundproofing structure 50 from different directions, thereby reducing transmission of noise, and can also play a role of noise reduction.

Those skilled in the art will understand that the disclosed scope of the present disclosure is not limited to the specific embodiments described above, and certain elements of the embodiments may be modified and replaced without departing from the spirit of the present application. The scope of the present application is limited only by the appended claims.
