DETAILED DESCRIPTION

Hereinafter, some embodiments of the present disclosure will be clearly and completely described with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, but not all embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by those ordinarily skilled in the art fall within the scope of protection of the present disclosure.

In related air conditioners, an air conditioner generally includes an air inlet pipe connected to the outdoors. During weather such as strong wind and heavy rain, rainwater easily enters the air conditioner through the air inlet pipe and flows to a ground surface along an outer shell of the air conditioner, causing customer complaints.

To solve the foregoing problem, as shown in FIG. 1, in an air conditioner disposed in some embodiments of the present disclosure, the air conditioner comprises a housing 1. The housing 1 is configured to be an outer shell of the exterior of the air conditioner. An interior of the housing 1 is used for providing a mounting space.

In some embodiments, the housing 1 has a rectangular hollow structure. A length direction of the housing 1 is disposed along a height direction, so that the air conditioner is disposed upright at a site of use, which increases a height of the air conditioner and reduces space occupation of the air conditioner.

As shown in FIG. 1 and FIG. 2, in some embodiments, the housing 1 comprises a main shell 11. The main shell 11 is disposed to extend along the height direction. A height dimension of the main shell 11 is greater than a left-right width dimension and a front-rear width dimension of the main shell 11, so as to increase the height of the housing 1 and reduce the space occupation of the housing 1.

As shown in FIG. 1 and FIG. 3, in some embodiments, the housing 1 comprises a chassis 12. The chassis 12 is disposed at a bottom of the main shell 11. An accommodating space 10 is formed above a top of the chassis 12 and inside the main shell 11. The accommodating space 10 is used as a mounting space for other components of the air conditioner.

As shown in FIG. 1 and FIG. 3, in some embodiments, a circumferential side of the chassis 12 is provided with a base foot 13. The base foot 13 is disposed to extend toward an outer periphery direction of the chassis 12, and the base foot 13 is used for increasing a contact area between a bottom of the housing 1 and a ground surface, thereby improving reliability of support of the chassis 12 for the air conditioner and improving stability of the air conditioner.

As shown in FIG. 1 and FIG. 3, in some embodiments, a plurality of the base feet 13 are provided. The plurality of base feet 13 are connected sequentially end-to-end, so that the plurality of base feet 13 are disposed circumferentially around the circumferential side of the chassis 12. In this way, the plurality of base feet 13 form an annular structure disposed on an outer circumferential side of the chassis 12, which improves a structural strength among the plurality of base feet 13 and forms a complete annular structure; at the same time, bumping of a user against the base foot 13 is avoided, improving safety in use of the air conditioner.

As shown in FIG. 3 and FIG. 4, in some embodiments, the air conditioner comprises a refrigerant circuit. The refrigerant circuit is disposed in the housing 1. The refrigerant circuit is disposed in the accommodating space 10. The refrigerant circuit comprises a compressor 21, an outdoor heat exchanger 22, and an indoor heat exchanger 23 connected end to end. A refrigerant circulates in the refrigerant circuit composed of the compressor 21, the outdoor heat exchanger 22, and the indoor heat exchanger 23. During a refrigerant circulation process, the outdoor heat exchanger 22 and the indoor heat exchanger 23 serve as a condenser and an evaporator, respectively, to cause the refrigerant to evaporate and absorb heat in the evaporator and to condense and release heat in the condenser, so that a refrigerating cycle or a heating cycle of the air conditioner can be executed.

Specifically, during the refrigerating cycle, the outdoor heat exchanger 22 serves as the condenser, and the indoor heat exchanger 23 serves as the evaporator. During the heating cycle, the outdoor heat exchanger 22 serves as the evaporator, and the indoor heat exchanger 23 serves as the condenser.

It should be noted that both the refrigerating cycle and the heating cycle include a series of processes, involving compression, condensation, expansion, and evaporation, and supplying the refrigerant to air that has been conditioned and has undergone heat exchange.

The compressor 21 is used for compressing a refrigerant gas and discharging the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser.

The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the ambient environment through the condensing process.

The evaporator evaporates the expanded refrigerant, and causes the refrigerant gas in a low-temperature and low-pressure state to return to the compressor 21. The evaporator can achieve a refrigerating effect through heat exchange with the surrounding environment by utilizing latent heat of evaporation of the refrigerant.

During the whole circulation, the air conditioner may adjust the temperature of the indoor space to improve the comfort level of the indoor space and enhance the usage experience of the user.

As shown in FIG. 2, FIG. 3, and FIG. 4, in some embodiments, the air conditioner comprises an outdoor fan assembly 3. The outdoor fan assembly 3 is disposed opposite to the outdoor heat exchanger 22. The outdoor fan assembly 3 is used for introducing outdoor air into an interior of the housing 1 to perform heat exchange with the outdoor heat exchanger 22, forming a heat exchange air flow.

For example, during the refrigerating cycle, the outdoor heat exchanger 22 serves as the condenser, and the outdoor fan assembly 3 draws external air and blows the external air toward the outdoor heat exchanger 22 to dissipate heat from the outdoor heat exchanger 22, so as to reduce a temperature of the outdoor heat exchanger 22. During the heating cycle, the outdoor heat exchanger 22 serves as the evaporator, and the outdoor fan assembly 3 draws the external air and blows the external air toward the outdoor heat exchanger 22 to raise a temperature of the outdoor heat exchanger 22, so as to increase the temperature of the outdoor heat exchanger 22.

As shown in FIG. 1, FIG. 2, and FIG. 3, in some embodiments, the air conditioner comprises an indoor fan assembly 4. The indoor fan assembly 4 is disposed opposite to the indoor heat exchanger 23. The indoor fan assembly 4 is used for introducing indoor air into the interior of the housing 1 to perform heat exchange with the indoor heat exchanger 23, forming a heat exchange air flow.

For example, during the refrigerating cycle, the indoor heat exchanger 23 serves as the evaporator, and the indoor fan assembly 4 draws indoor air from outside the housing 1, blows the indoor air toward the indoor heat exchanger 23 to perform heat exchange with the indoor heat exchanger 23, reduces a temperature of the air flowing through the indoor heat exchanger 23, and blows the air with the reduced temperature back indoors, so as to reduce an air temperature indoors.

As another example, during the heating cycle, the indoor heat exchanger 23 serves as the condenser, and the outdoor fan assembly 3 draws the indoor air from outside the housing 1, blows the indoor air toward the indoor heat exchanger 23 to perform heat exchange with the indoor heat exchanger 23, raises the temperature of the air flowing through the indoor heat exchanger 23, and blows the air with the raised temperature back indoors, so as to raise the air temperature indoors.

As shown in FIG. 3 and FIG. 4, in some embodiments, the compressor 21, the outdoor heat exchanger 22, the outdoor fan assembly 3, the indoor heat exchanger 23, and the indoor fan assembly 4 are respectively disposed in the accommodating space 10 inside the housing 1, such that the housing 1 provides a covering and protective effect, which can prevent damage to the structure caused by erosion of foreign matter from the outside or impact of an external force, thereby improving structural reliability of the air conditioner and ensuring normal operation of the air conditioner.

As shown in FIG. 3 and FIG. 4, in some embodiments, the accommodating space 10 inside the housing 1 comprises three layers of sub-spaces. The three layers of sub-spaces are a first sub-space 110, a second sub-space 120, and a third sub-space 130 disposed sequentially from bottom to top. The compressor 21 is disposed in the first sub-space 110. The outdoor heat exchanger 22 and the outdoor fan assembly 3 are disposed in the second sub-space 120. The indoor heat exchanger 23 and the indoor fan assembly 4 are disposed in the third sub-space 130. In this way, through the three layers of sub-spaces from bottom to top, components such as the compressor 21, the outdoor heat exchanger 22, the outdoor fan assembly 3, the indoor heat exchanger 23, and the indoor fan assembly 4 are dispersedly disposed at different height positions inside the housing 1, which is conducive to increasing an overall height of the air conditioner, reducing width and thickness dimensions of the air conditioner, and reducing space occupation of the air conditioner at a site of use.

As shown in FIG. 2, FIG. 3, and FIG. 4, in some embodiments, an outer wall of the housing 1 is provided with an indoor air inlet 111. The indoor air inlet 111 is in communication with an exterior of the housing 1. The indoor air inlet 111 is in communication with an indoor space. The indoor air inlet 111 is disposed on an outer wall corresponding to the third sub-space 130, and the indoor air inlet 111 is disposed opposite to an air inlet end of the indoor heat exchanger 23 and the indoor fan assembly 4. In this way, when the indoor fan assembly 4 is in operation, the indoor fan assembly 4 can draw indoor air into the interior of the housing 1 through the indoor air inlet 111 to perform heat exchange with the indoor heat exchanger 23, and the air after heat exchange is discharged again to the indoor space outside the housing 1 through an air outlet end of the indoor fan assembly 4.

As shown in FIG. 1, FIG. 3, and FIG. 4, in some embodiments, the outer wall of the housing 1 is provided with an indoor air outlet 112. The indoor air outlet 112 is in communication with the exterior of the housing 1. The indoor air outlet 112 is in communication with the indoor space. The indoor air outlet 112 is disposed on the outer wall corresponding to the third sub-space 130, and the indoor air outlet 112 is disposed opposite to the air outlet end of the indoor fan assembly 4. In this way, when the indoor fan assembly 4 is in operation, the indoor fan assembly 4 draws the indoor air through the indoor air inlet 111, and after performing heat exchange with the indoor heat exchanger 23, the indoor air is discharged again to the indoor space outside the housing 1 through the air outlet end of the indoor fan assembly 4 and the indoor air outlet 112.

As shown in FIG. 1 and FIG. 3, in some embodiments, the outer wall of the housing 1 is provided with an air deflector 113. The air deflector 113 is rotatably disposed at the indoor air outlet 112. A plurality of the air deflectors 113 are provided, and the plurality of air deflectors 113 are disposed side by side at the indoor air outlet 112. When the air deflector 113 rotates, the air deflector 113 opens or closes the indoor air outlet 112. When the air deflector 113 rotates to open the indoor air outlet 112, the air deflector 113 can also change an air outlet direction of the indoor air outlet 112.

As shown in FIG. 2 and FIG. 4, in some embodiments, the air conditioner comprises an air inlet pipe 14. The air inlet pipe 14 is disposed in a space outside the housing 1. The air inlet pipe 14 is used for introducing outdoor air. One end of the air inlet pipe 14 is in communication with an air inlet end of the outdoor fan assembly 3. The other end of the air inlet pipe 14 is in communication with an outdoor space. An air outlet end of the outdoor fan assembly 3 is disposed to face the outdoor heat exchanger 22. In this way, the outdoor fan assembly 3 can draw air from the outdoor space through the air inlet pipe 14, introduce the outdoor air into the interior of the housing 1, and blow the outdoor air toward the outdoor heat exchanger 22 to raise or lower a temperature of the outdoor heat exchanger 22.

As shown in FIG. 2 and FIG. 4, the air conditioner comprises an air outlet pipe 15. The air outlet pipe 15 is disposed in the space outside the housing 1. The air outlet pipe 15 is used for exhausting air to the outdoors, so as to discharge air inside the housing 1 to the outdoors. One end of the air outlet pipe 15 is in communication with an interior space of the housing 1. The other end of the air outlet pipe 15 is in communication with the outdoor space. In this way, when the outdoor fan assembly 3 is in operation, the outdoor fan assembly 3 can draw air from the outdoor space through the air inlet pipe 14, introduce the outdoor air into the interior of the housing 1, and blow the outdoor air toward the outdoor heat exchanger 22, and cause the air inside the housing 1 that has flowed through the outdoor heat exchanger 22 to be discharged to the outdoor space through the air outlet pipe 15, achieving an outdoor air circulation.

It should be noted that, in other embodiments, the air inlet pipe 14 is also used for exhausting air, and the air outlet pipe 15 is also used for intaking air. The air outlet pipe 15 can introduce outdoor air into the interior of the housing 1 for heat exchange with the outdoor heat exchanger 22. The air after heat exchange can be delivered to the outdoors through the air inlet pipe 14 under an action of the outdoor fan assembly 3.

As shown in FIG. 2 and FIG. 4, in some embodiments, the air inlet pipe 14 and the air outlet pipe 15 are disposed on an outer side of the third sub-space 130. An upper part of the housing 1 is provided with a receiving region 140 recessed in an outer wall corresponding to the third sub-space 130. The air inlet pipe 14 and the air outlet pipe 15 are disposed in the receiving region 140, such that the air inlet pipe 14 and the air outlet pipe 15 are disposed above the second sub-space 120, and such that the air inlet pipe 14 and the air outlet pipe 15 are disposed above the outdoor heat exchanger 22 and the outdoor fan assembly 3.

As shown in FIG. 2 and FIG. 4, in some embodiments, the air inlet pipe 14 and the air outlet pipe 15 are disposed side by side in the receiving region 140 on the outer wall of the housing 1. A lower end of the air inlet pipe 14 is in communication with the air inlet end of the outdoor fan assembly 3. A lower end of the air outlet pipe 15 is in communication with the second sub-space 120 inside the housing 1. An upper end of the air inlet pipe 14 and an upper end of the air outlet pipe 15 are connected to the outdoor space. During an mounting process of the air conditioner, the air inlet pipe 14 and the air outlet pipe 15 are elongated and are installed and fixed on a wall or a window, thereby communicating with the outdoor space.

As shown in FIG. 3 and FIG. 4, in some embodiments, the air conditioner comprises a second water receiving tray 5. The second water receiving tray 5 is disposed in the accommodating space 10 inside the housing 1. The second water receiving tray 5 is disposed in a region between the first sub-space 110 and the second sub-space 120. The outdoor heat exchanger 22 is provided above the second water receiving tray 5. The second water receiving tray 5 is used for receiving condensate water flowing down from an outer wall of the outdoor heat exchanger 22. When the air conditioner performs heating, a refrigerant evaporates and absorbs heat in the outdoor heat exchanger 22, which causes a surface temperature of the outdoor heat exchanger 22 to decrease, and water vapor in the air condenses into water upon encountering cold, thereby falling into the second water receiving tray 5 at a bottom of the outdoor heat exchanger 22, and being collected in the second water receiving tray 5 or discharged through a drainage outlet on the second water receiving tray 5, which can prevent the condensate water from dripping onto the ground surface and causing a risk of the air conditioner slipping and a person falling.

As shown in FIG. 3 and FIG. 4, in some embodiments, a bottom port of the air outlet pipe 15 is disposed in a space above the second water receiving tray 5. After rainwater from the outdoors enters the housing 1 through the air outlet pipe 15, the rainwater is received by the second water receiving tray 5, which prevents the rainwater from flowing directly to other regions inside the housing 1, or seeping out of the housing 1 to flow to the ground surface.

As shown in FIG. 4 and FIG. 5, in some embodiments, a side wall of the second water receiving tray 5 is provided with a first drainage outlet 51. The first drainage outlet 51 is provided with a drain valve 52. The drain valve 52 blocks the first drainage outlet 51. When the drain valve 52 opens the first drainage outlet 51, the first drainage outlet 51 is in communication with an exterior of the second water receiving tray 5, and water in the second water receiving tray 5 flows out of the second water receiving tray 5 through the first drainage outlet 51.

As shown in FIG. 2 and FIG. 4, the drain valve 52 is provided outside the housing 1, and the first drainage outlet 51 is in communication with the exterior of the housing 1. When the drain valve 52 opens the first drainage outlet 51, the water in the second water receiving tray 5 flows out to the exterior of the housing 1 through the first drainage outlet 51.

As shown in FIG. 3 and FIG. 4, in some embodiments, the air conditioner comprises a first water receiving tray 6. The first water receiving tray 6 is disposed in the accommodating space 10 inside the housing 1. The first water receiving tray 6 is disposed in a region between the second sub-space 120 and the third sub-space 130. The indoor heat exchanger 23 is provided above the first water receiving tray 6. The indoor fan assembly 4 is provided above the first water receiving tray 6. The first water receiving tray 6 is used for receiving condensate water flowing down from an outer wall of the indoor heat exchanger 23. When the air conditioner performs cooling, a refrigerant evaporates and absorbs heat in the indoor heat exchanger 23, which causes a surface temperature of the indoor heat exchanger 23 to decrease, and water vapor in the air condenses into water upon encountering cold, thereby falling into the first water receiving tray 6 at a bottom of the indoor heat exchanger 23, and being collected in the first water receiving tray 6 or discharged through a drainage outlet on the first water receiving tray 6, which can prevent the condensate water from dripping onto the ground surface and causing a risk of the air conditioner slipping and a person falling.

As shown in FIG. 3 and FIG. 4, in some embodiments, a bottom surface of the first water receiving tray 6 is provided with a second drainage outlet (not shown in the figure). The second drainage outlet is provided above the outdoor heat exchanger 22 and the second water receiving tray 5. Condensate water in the first water receiving tray 6 flows to the outdoor heat exchanger 22 through the second drainage outlet to cool the outdoor heat exchanger 22, and then flows downward to the second water receiving tray 5 along the outer wall of the outdoor heat exchanger 22. In this way, the condensate water in the first water receiving tray 6 is discharged to be collected in the second water receiving tray 5, and the outdoor heat exchanger 22 is cooled through heat exchange between the condensate water and the outdoor heat exchanger 22. For example, when the air conditioner performs cooling, the outdoor heat exchanger 22 serves as a condenser and needs to dissipate heat to the outside, and the indoor heat exchanger 23 serves as an evaporator and needs to absorb heat from the outside. Air condenses into condensate water on a surface of the indoor heat exchanger 23, the condensate water flows to the first water receiving tray 6 along the surface of the indoor heat exchanger 23, flows to the outer wall of the outdoor heat exchanger 22 through the second drainage outlet of the first water receiving tray 6 to dissipate heat from and cool the outdoor heat exchanger 22, and finally flows downward to be collected in the second water receiving tray 5 along the outer wall of the outdoor heat exchanger 22.

The air conditioner comprises an outdoor fan assembly 3, where the outdoor fan assembly 3 is disposed on one side of the outdoor heat exchanger 22 to drive outdoor air to flow through the outdoor heat exchanger 22 for heat exchange. The air conditioner comprises an indoor fan assembly 4, where the indoor fan assembly 4 is disposed on one side of the indoor heat exchanger 23 to drive indoor air to flow through the indoor heat exchanger 23 for heat exchange. The air conditioner comprises a second water receiving tray 5, and the outdoor heat exchanger 22 is provided above the second water receiving tray 5. The air conditioner comprises a first water receiving tray 6, and the indoor heat exchanger 23 is provided above the first water receiving tray 6. The first water receiving tray 6 is provided above the outdoor heat exchanger 22. The air conditioner comprises an air inlet pipe 14, where the air inlet pipe 14 is used for sending outdoor air to the outdoor heat exchanger 22 for heat exchange. The air conditioner comprises an air outlet pipe 15, where the air outlet pipe 15 is used for sending the heat-exchanged air to the outdoors under an action of the outdoor fan assembly 3. The air inlet pipe and the air outlet pipe are provided above the outdoor heat exchanger and are spaced apart from the indoor fan assembly in a horizontal direction. The compressor is disposed at a bottom of the shell, and the first water receiving tray is provided above the compressor.

As shown in FIG. 4 and FIG. 5, in some embodiments, the air conditioner comprises a support member 7. The support member 7 is disposed in the housing 1. The support member 7 is disposed in the main shell 11. The support member 7 is disposed in the accommodating space 10. The support member 7 is used for supporting an internal structure of the air conditioner. For example, the support member 7 is used for supporting the outdoor heat exchanger 22, the outdoor fan assembly 3, the second water receiving tray 5, the indoor heat exchanger 23, the indoor fan assembly 4, the first water receiving tray 6, etc., thereby increasing a structural strength and structural stability of an interior of the air conditioner.

As shown in FIG. 4 and FIG. 5, in some embodiments, a lower part of the support member 7 is disposed in the first sub-space 110, and a bottom end of the support member 7 is supported and fixed on the chassis 12. An upper part of the support member 7 is disposed in the second sub-space 120, and a top end of the support member 7 is supported on a bottom of the first water receiving tray 6, which facilitates mounting of the indoor heat exchanger 23 and the indoor fan assembly 4 on the first water receiving tray 6, such that the indoor heat exchanger 23 and the indoor fan assembly 4 are supported on the top end of the support member 7 through the first water receiving tray 6, thereby improving structural stability of the indoor heat exchanger 23 and the indoor fan assembly 4 in the third sub-space 130.

As shown in FIG. 4 and FIG. 5, in some embodiments, the second water receiving tray 5 is supported and fixed on the upper part of the support member 7, which facilitates mounting of the outdoor heat exchanger 22 on the second water receiving tray 5, and being supported and fixed on the support member 7 through the second water receiving tray 5. The outdoor fan assembly 3 is disposed on the upper part of the support member 7. In this way, it is convenient to improve the structural stability of the outdoor heat exchanger 22 and the outdoor fan assembly 3 in the second sub-space 120.

It should be noted that, in other embodiments, the support member 7 is also used for supporting any one or more of the outdoor heat exchanger 22, the outdoor fan assembly 3, the second water receiving tray 5, the indoor heat exchanger 23, the indoor fan assembly 4, and the first water receiving tray 6. For example, the support member 7 is also used for separately supporting the outdoor heat exchanger 22 and/or the indoor heat exchanger 23.

In some embodiments, the outdoor fan assembly 3 comprises an outdoor air duct shell 30. An outdoor air duct is formed in an interior of the outdoor air duct shell 30. An air inlet end of the outdoor air duct shell 30 is in communication with the outdoors, and an air outlet end of the outdoor air duct shell 30 faces the outdoor heat exchanger 22. Specifically, the air inlet end of the outdoor air duct shell 30 is in communication with the air inlet pipe 14, and communicates with the outdoor space through the air inlet pipe 14. The air outlet end of the outdoor air duct shell 30 is disposed to face the outdoor heat exchanger 22. In this way, the air duct in the outdoor air duct shell 30 can draw air from the outdoor space through the air inlet pipe 14, introduce the outdoor air into the interior of the housing 1, and blow the outdoor air toward the outdoor heat exchanger 22 to raise or lower a temperature of the outdoor heat exchanger 22.

As shown in FIG. 5, FIG. 6, and FIG. 7, in some embodiments, the outdoor air duct shell 30 comprises a volute component 31. The volute component 31 is fixed on the support member 7. The air duct in the outdoor air duct shell 30 is formed in the volute component 31.

It should be noted that, in other embodiments, the outdoor air duct shell 30 does not adopt the volute component 31, that is, a volute structure is not adopted, and the outdoor air duct shell 30 adopts an air duct shell component of another shape.

As shown in FIG. 6 and FIG. 7, in some embodiments, the upper part of the support member 7 forms a volute portion 71. The volute component 31 is fixed on the volute portion 71, so that the volute component 31 is fixed on the support member 7.

The second snap fastener 1511 extends into the second mounting opening 162 and is rotatably snapped on a side of the second limiting rib 1621 away from the air outlet pipe 15. By the second limiting rib 1621 being uniformly distributed circumferentially on the inner circumferential wall of the second mounting opening 162, when the air outlet pipe 15 drives the second connector 151 to rotate in the second mounting opening 162, the second snap fastener 1511 is capable of rotating circumferentially along the second limiting rib 1621 in the second mounting opening 162. At this time, the second snap fastener 1511 remains snapped on the side of the second limiting rib 1621 away from the air outlet pipe 15, thereby keeping the second connector 151 rotatably connected in the second mounting opening 162 and preventing the second connector 151 from detaching from the second mounting opening 162. In this way, not only a rotatable connection between the second connector 151 and the second mounting opening 162 can be achieved, but also accidental detachment of the second connector 151 from the second mounting opening 162 can be effectively prevented, thereby ensuring connection stability and reliability of the air outlet pipe 15.

As shown in FIG. 6, FIG. 12, and FIG. 13, in some embodiments, the second snap fastener 1511 is disposed on an inner wall of the second extension wall 1512 and is disposed to extend downward from the inner wall of the second extension wall 1512. The second snap fastener 1511 is snapped on a bottom side of the second limiting rib 1621, and the second extension wall 1512 abuts against a top side of the second limiting rib 1621. In this way, by cooperation of the second extension wall 1512 and the second snap fastener 1511 being respectively snapped on upper and lower sides of the second limiting rib 1621, the connection reliability between the second connector 151 and the second mounting opening 162 of the mounting base 16 is improved. When the second connector 151 rotates relative to the second mounting opening 162, the second extension wall 1512 rotatably abuts against the top side of the second limiting rib 1621, and the second snap fastener 1511 is rotatably snapped on the bottom side of the second limiting rib 1621, thereby maintaining the rotatable connection between the second connector 151 and the second mounting opening 162 and ensuring the connection stability and reliability of the air outlet pipe 15. The air conditioner of the embodiments of the present disclosure is also used for solving a problem of drainage blockage of a water receiving tray and a problem of condensate water splashing from an evaporator outlet pipe.

To solve the foregoing problem, as shown in FIG. 1 and FIG. 2, in an air conditioner disposed in some embodiments of the present disclosure, the air conditioner comprises a housing 1. The housing 1 is configured to be an outer shell of the exterior of the air conditioner.

As shown in FIG. 3 and FIG. 4, in some embodiments, the air conditioner comprises a refrigerant circuit. The refrigerant circuit is disposed in the housing 1. The refrigerant circuit is disposed in the accommodating space 10. The refrigerant circuit comprises a compressor 21, an outdoor heat exchanger 22, and an indoor heat exchanger 23 connected end to end. A refrigerant circulates in the refrigerant circuit composed of the compressor 21, the outdoor heat exchanger 22, and the indoor heat exchanger 23. During a refrigerant circulation process, the outdoor heat exchanger 22 and the indoor heat exchanger 23 serve as a condenser and an evaporator, respectively, to cause the refrigerant to evaporate and absorb heat in the evaporator and to condense and release heat in the condenser, so that a refrigerating cycle or a heating cycle of the air conditioner can be executed.

As shown in FIG. 2, FIG. 3, and FIG. 4, in some embodiments, the air conditioner comprises an outdoor fan assembly 3. The outdoor fan assembly 3 is disposed opposite to the outdoor heat exchanger 22. The outdoor fan assembly 3 is used for introducing outdoor air into an interior of the housing 1 to perform heat exchange with the outdoor heat exchanger 22, forming a heat exchange air flow.

As shown in FIG. 1, FIG. 2, and FIG. 3, in some embodiments, the air conditioner comprises an indoor fan assembly 4. The indoor fan assembly 4 is disposed opposite to the indoor heat exchanger 23. The indoor fan assembly 4 is used for introducing indoor air into the interior of the housing 1 to perform heat exchange with the indoor heat exchanger 23, forming a heat exchange air flow.

As shown in FIG. 3 and FIG. 4, in some embodiments, the air conditioner comprises a second water receiving tray 5. The outdoor heat exchanger 22 is provided above the second water receiving tray 5. The second water receiving tray 5 is used for receiving condensate water flowing down from an outer wall of the outdoor heat exchanger 22.

As shown in FIG. 3 and FIG. 4, in some embodiments, the air conditioner comprises a first water receiving tray 6. The first water receiving tray 6 is disposed in the housing 1. The indoor heat exchanger 23 is provided above the first water receiving tray 6. The first water receiving tray 6 is used for receiving condensate water flowing down from an outer wall of the indoor heat exchanger 23.

In some embodiments, the indoor fan assembly 4 is provided above the first water receiving tray 6. The indoor fan assembly 4 is disposed on one side of the indoor heat exchanger 23 in a horizontal direction. The first water receiving tray 6 is used for providing an mounting space for the indoor fan assembly 4, so that the indoor fan assembly 4 and the indoor heat exchanger 23 are disposed adjacent to each other in the horizontal direction, thereby causing the indoor air introduced by the indoor fan assembly 4 to perform heat exchange with the indoor heat exchanger 23 in proximity, which is conducive to improving a heat exchange efficiency of the indoor heat exchanger 23.

As shown in FIG. 26, FIG. 27, and FIG. 28, in some embodiments, the first water receiving tray 6 is provided above a top surface of the outdoor heat exchanger 22. A bottom surface of the first water receiving tray 6 abuts against the top surface of the outdoor heat exchanger 22. In this way, the first water receiving tray 6 is simultaneously supported above tops of the support member 7 and the outdoor heat exchanger 22, improving stability of the first water receiving tray 6.

It should be noted that, in other embodiments, there is also a gap of a certain width between the bottom surface of the first water receiving tray 6 and the top surface of the outdoor heat exchanger 22.

As shown in FIG. 26 and FIG. 27, in some embodiments, a top of the outdoor heat exchanger 22 abuts against the bottom surface of the first water receiving tray 6, and a bottom of the outdoor heat exchanger 22 is supported on the second water receiving tray 5. In this way, the outdoor heat exchanger 22 is clamped in a region between the first water receiving tray 6 and the second water receiving tray 5, improving reliability and structural stability of the outdoor heat exchanger 22.

As shown in FIG. 27 and FIG. 30, in some embodiments, an inner bottom surface of the first water receiving tray 6 is provided with a water outlet 611. The water outlet 611 is provided above the outdoor heat exchanger 22 and the second water receiving tray 5. The water outlet 611 is provided above the top surface of the outdoor heat exchanger 22. Condensate water in the first water receiving tray 6 flows downward through the water outlet 611, flows to the top surface of the outdoor heat exchanger 22, flows downward along the outer wall of the outdoor heat exchanger 22 to cool the outdoor heat exchanger 22, and finally flows into and is collected in the second water receiving tray 5. In this way, the condensate water in the first water receiving tray 6 is discharged to be collected in the second water receiving tray 5, and the outdoor heat exchanger 22 is cooled through heat exchange between the condensate water and the outdoor heat exchanger 22. For example, when the air conditioner performs cooling, the outdoor heat exchanger 22 serves as a condenser and needs to dissipate heat to the outside, and the indoor heat exchanger 23 serves as an evaporator and needs to absorb heat from the outside. Air condenses into condensate water on a surface of the indoor heat exchanger 23, the condensate water flows to the first water receiving tray 6 along the surface of the indoor heat exchanger 23, flows to the outer wall of the outdoor heat exchanger 22 through the water outlet 611 of the first water receiving tray 6 to dissipate heat from and cool the outdoor heat exchanger 22, and finally flows downward to be collected in the second water receiving tray 5 along the outer wall of the outdoor heat exchanger 22.

As shown in FIG. 28 and FIG. 30, in some embodiments, a top surface of the first water receiving tray 6 is provided with a first water receiving groove 61. The indoor heat exchanger 23 is provided above the first water receiving groove 61. The water outlet 611 is disposed on a groove bottom surface of the first water receiving groove 61. In this way, condensate water formed on the indoor heat exchanger 23 falls downward into the first water receiving groove 61 and is discharged downward through the water outlet 611.

As shown in FIG. 28 and FIG. 30, in some embodiments, a top surface of the second water receiving tray 5 is provided with a second water receiving groove 53. The outdoor heat exchanger 22 is provided above the second water receiving tray 5. The water outlet 611 is located above the second water receiving groove 53. The drainage outlet 51 is in communication with the second water receiving groove 53. In this way, water discharged downward from the water outlet 611 flows through the outdoor heat exchanger 22 and finally falls downward into the second water receiving groove 53, so as to be conveniently collected in the second water receiving groove 53 or discharged through the drainage outlet 51.

As shown in FIG. 27 and FIG. 28, in some embodiments, the second water receiving tray 5 is provided with a water splashing wheel 54. The water splashing wheel 54 is rotatably disposed in the second water receiving groove 53. When the water splashing wheel 54 rotates, the water splashing wheel 54 splashes up condensate water in the second water receiving groove 53, so that the condensate water splashes onto a surface of the outdoor heat exchanger 22, and the condensate water is used to cool the surface of the outdoor heat exchanger 22. The condensate water flows downward along the surface of the outdoor heat exchanger 22 under an action of gravity, and thus falls back into the second water receiving groove 53, and then the condensate water in the second water receiving groove 53 is splashed up again by the water splashing wheel 54, and so on repeatedly. In this way, not only self-treatment of the condensate water in the second water receiving groove 53 can be achieved, but also a heat exchange efficiency of the outdoor heat exchanger 22 can be improved.

As shown in FIG. 27 and FIG. 28, in some embodiments, the outdoor heat exchanger 22 comprises a first heat exchange part 221 and a second heat exchange part 222. The first heat exchange part 221 and the second heat exchange part 222 are disposed with a horizontal interval. The first heat exchange part 221 and the second heat exchange part 222 are respectively provided above the second water receiving groove 53. The water splashing wheel 54 is disposed at a bottom of a spaced region of the first heat exchange part 221 and the second heat exchange part 222. In this way, when the water splashing wheel 54 rotates, the water splashing wheel 54 splashes up the condensate water in the second water receiving groove 53, so that the condensate water respectively splashes onto surfaces of the first heat exchange part 221 and the second heat exchange part 222, thereby increasing a contact area between the condensate water and the outdoor heat exchanger 22 and further improving the heat exchange efficiency of the outdoor heat exchanger 22.

As shown in FIG. 27 and FIG. 28, in some embodiments, the second water receiving tray 5 is provided with a water splashing driving member 55. An output shaft of the water splashing driving member 55 is in transmission connection with the water splashing wheel 54. The water splashing driving member 55 is used for driving the water splashing wheel 54 to rotate in the second water receiving groove 53.

As shown in FIG. 29 and FIG. 30, in some embodiments, the first water receiving groove 61 has a water outlet end 610. The water outlet 611 is disposed on a bottom surface of the water outlet end 610. The water outlet end 610 of the first water receiving groove 61 is located at a lowest point of the first water receiving groove 61. In this way, the condensate water dripping into the first water receiving groove 61 automatically flows to the water outlet end 610 of the first water receiving groove 61, so that the condensate water is smoothly discharged through the water outlet 611, improving a drainage efficiency of the first water receiving groove 61.

As shown in FIG. 30, in some embodiments, the first water receiving groove 61 is a long strip-shaped structure. Opposite ends of the first water receiving groove 61 are respectively a first end 61a and a second end 61b. The first end 61a of the first water receiving groove 61 and the second end 61b of the first water receiving groove 61 are respectively located at opposite ends of the first water receiving groove 61 in a length direction. The water outlet end 610 of the first water receiving groove 61 is located at the first end 61a or the second end 61b. Specifically, when the water outlet end 610 of the first water receiving groove 61 is located at the first end 61a, the first end 61a of the first water receiving groove 61 is the lowest point of the first water receiving groove 61, and the water outlet 611 is disposed on a bottom surface of the first end 61a, as shown in FIG. 10. When the water outlet end 610 of the first water receiving groove 61 is located at the second end 61b, the second end 61b of the first water receiving groove 61 is the lowest point of the first water receiving groove 61, and the water outlet 611 is disposed on a bottom surface of the second end 61b.

It should be noted that, in other embodiments, the water outlet end 610 of the first water receiving groove 61 is also disposed at a middle part or another position of the first water receiving groove 61.

As shown in FIG. 30 and FIG. 31, in some embodiments, the bottom surface of the first water receiving groove 61 is provided with a water guiding slope 612. The water guiding slope 612 is disposed to be inclined downward toward a direction close to the water outlet end 610. In this way, the condensate water in the first water receiving groove 61 flows along the water guiding slope 612 toward the direction of the water outlet end 610 and flows to the water outlet 611, improving the drainage efficiency of the first water receiving groove 61.

As shown in FIG. 30, FIG. 31, and FIG. 32, in some embodiments, the water outlet end 610 of the first water receiving groove 61 is provided with a plurality of water outlets 611, and the plurality of water outlets 611 are sequentially adjacent to and separated from each other. A partitioning rib 613 is provided between adjacent water outlets 611. A plurality of the partitioning ribs 613 are provided, and the plurality of partitioning ribs 613 are sequentially provided between two adjacent water outlets 611. In this way, the plurality of water outlets 611 are sequentially separated by the partitioning ribs 613, so that the plurality of water outlets 611 are sequentially adjacent to and separated from each other.

As shown in FIG. 30, FIG. 31, and FIG. 32, in some embodiments, the partitioning rib 613 protrudes at a top opening of the water outlet 611. The partitioning rib 613 protrudes on the groove bottom surface of the water outlet end 610 of the first water receiving groove 61. One end of the partitioning rib 613 is disposed to extend toward a direction of the water guiding slope 612. A water guiding channel 614 is formed between adjacent partitioning ribs 613, and one end of the water guiding channel 614 is in corresponding communication with one water outlet 611. A plurality of water guiding channels 614 are formed between the plurality of partitioning ribs 613, and the plurality of water guiding channels 614 are in corresponding communication with the plurality of water outlets 611. In this way, the plurality of water guiding channels 614 are formed on the groove bottom surface of the water outlet end 610 of the first water receiving groove 61, so that the condensate water in the first water receiving groove 61 flowing toward the water outlet end 610 is shunted and discharged through different water guiding channels 614 and corresponding water outlets 611. The condensate water can be independently separated when entering the corresponding water outlets 611, which is conducive to ensuring smooth water discharge of each of the water outlets 611, and thus is conducive to improving water discharge smoothness and water discharge efficiency of the first water receiving groove 61.

As shown in FIG. 31, FIG. 32, and FIG. 33, in some embodiments, the water outlet 611 is a non-circular hole. A shape of the water outlet 611 is non-circular. In this way, by providing the water outlet 611 as a non-circular hole, when the condensate water passes through the water outlet 611, the non-circular hole can break a surface tension of the condensate water, which improves a water discharge smoothness of the water outlet 611 and is conducive to improving a water discharge speed and a water discharge efficiency of the first water receiving groove 61.

As shown in FIG. 32, in some embodiments, a side edge of the water outlet 611 close to the water guiding slope 612 is formed with a drainage groove 615. In a direction from the water guiding slope 612 toward the water outlet 611, a width of the drainage groove 615 gradually increases. For example, the drainage groove 615 is a V-shaped groove structure. A tip of the V-shaped groove structure is disposed toward a direction of the water guiding slope 612. In this way, by providing the drainage groove 615 at the side edge of the water outlet 611, the water outlet 611 forms a non-circular hole structure, which is conducive to breaking the surface tension of the condensate water flowing through the water outlet 611 and improving the drainage speed and the drainage efficiency of the water outlet 611. When the condensate water of the first water receiving groove 61 flows to the water outlet 611 through the water guiding slope 612, the condensate water can preferentially contact a side where the drainage groove 615 of the water outlet 611 is located, and flow downward into the water outlet 611 along a groove wall of the drainage groove 615, thereby improving the water discharge smoothness of the water outlet 611.

It should be noted that, in other embodiments, the water outlet 611 also adopts a non-circular hole-like structure of another shape.

As shown in FIG. 33, in some embodiments, a top side groove surface of the drainage groove 615 is disposed to be inclined downward toward a direction away from the water guiding slope 612. When the condensate water of the first water receiving groove 61 flows from the water guiding slope 612 to the water outlet 611, the condensate water of the first water receiving groove 61 flows obliquely downward into the water outlet 611 along the groove wall of the drainage groove 615, improving the water discharge smoothness and the water discharge efficiency of the water outlet 611.

It should be noted that, in some embodiments, the top side groove surface of the drainage groove 615 is a flat inclined surface structure, or the top side groove surface of the drainage groove 615 is also a smooth arc-shaped surface structure.

As shown in FIG. 33 and FIG. 34, in some embodiments, the bottom surface of the first water receiving tray 6 is recessed with a clearance cavity 62. The clearance cavity 62 is located above the top surface of the outdoor heat exchanger 22. The water outlet 611 is located on a top side wall of the clearance cavity 62. In this way, through a structural design of the clearance cavity 62, a distance between the water outlet 611 and the top surface of the outdoor heat exchanger 22 is increased, so that the water outlet 611 is suspended above the top surface of the outdoor heat exchanger 22. When the condensate water in the first water receiving tray 6 flows downward through the water outlet 611, the condensate water needs to flow through the clearance cavity 62 before flowing to the top surface of the outdoor heat exchanger 22. Since the clearance cavity 62 is located between the water outlet 611 and the top surface of the outdoor heat exchanger 22, it is difficult for dust or dirt in the condensate water to block the clearance cavity 62, so that a problem that the water outlet 611 is easily blocked can be effectively solved, drainage of the water outlet 611 of the first water receiving tray 6 can be ensured to be smooth, and thus the drainage efficiency and a drainage performance of the first water receiving tray 6 are improved.

As shown in FIG. 33 and FIG. 34, in some embodiments, a gap h1 between a lower port of the water outlet 611 and the top surface of the outdoor heat exchanger 22 is greater than 1.5 mm. In a case where the clearance cavity 62 has a sufficient height, the gap h1 between the lower port of the water outlet 611 and the top surface of the outdoor heat exchanger 22 is greater than 1.5 mm, which can maintain a sufficient distance between the water outlet 611 and the top surface of the outdoor heat exchanger 22, and prevent dust or dirt in the condensate water from being blocked in a spaced region between the lower port of the water outlet 611 and the top surface of the outdoor heat exchanger 22, thereby effectively solving the problem that the water outlet 611 is easily blocked. Conversely, if the gap h1 between the lower port of the water outlet 611 and the top surface of the outdoor heat exchanger 22 is less than 1.5 mm, it cannot be ensured that there is a sufficient distance between the water outlet 611 and the top surface of the outdoor heat exchanger 22.

As shown in FIG. 33 and FIG. 34, in some embodiments, the top side wall of the clearance cavity 62 is provided with a flanged rib 621 protruding downward. The flanged rib 621 is disposed at a side edge of the lower port of the water outlet 611. In this way, by providing the flanged rib 621 at the side edge of the lower port of the water outlet 611, a bottom end of the flanged rib 621 is lower than the top side wall of the clearance cavity 62. When water is discharged downward at the water outlet 611, the condensate water flows downward along a side wall of the water outlet 611 and drips from a bottom surface of the flanged rib 621. It is difficult for the condensate water to climb over the flanged rib 621 to the top side wall of the clearance cavity 62 and then flow out through other side walls of the clearance cavity 62, thereby effectively solving and avoiding a problem of water leakage from the water outlet 611 to other regions of an outer wall of the water receiving tray.

As shown in FIG. 32, FIG. 33, and FIG. 34, in some embodiments, the flanged rib 621 is located below the drainage groove 615. The flanged rib 621 is disposed to extend downward from the groove wall of the drainage groove 615. In this way, by the flanged rib 621 extending downward from the groove wall of the drainage groove 615, the flanged rib 621 is overlapped below the drainage groove 615, so that a contour shape of the flanged rib 621 is similar to a contour shape of the drainage groove 615. When the condensate water of the first water receiving tray 6 is discharged at the water outlet 611, the condensate water can smoothly flow downward along the groove wall of the drainage groove 615 and a side wall of the flanged rib 621, improving the water discharge speed and the water discharge efficiency of the water outlet 611.

It should be noted that, in other embodiments, the flanged rib 621 also extends to other side edges of the water outlet 611 other than the groove wall of the drainage groove 615.

As shown in FIG. 32, FIG. 33, and FIG. 34, in some embodiments, a height h2 of the flanged rib 621 is greater than 1 mm. In this way, by the height h2 of the flanged rib 621 being greater than 1 mm, a height difference between the bottom surface of the flanged rib 621 and the top side wall of the clearance cavity 62 is greater than 1 mm, which can effectively increase a difficulty for the condensate water to climb over the flanged rib 621 to the top side wall of the clearance cavity 62, effectively ensure that the condensate water drips from the bottom surface of the flanged rib 621, and prevent the condensate water from flowing out through the other side walls of the clearance cavity 62. Conversely, if the height h2 of the flanged rib 621 is less than 1 mm, it cannot be ensured that the condensate water will not climb to the top side wall of the clearance cavity 62.

As shown in FIG. 32, FIG. 33, and FIG. 34, in some embodiments, at the water outlet 611, a bottom of the partitioning rib 613 is connected to the flanged rib 621. In this way, at the water outlet 611, the bottom of the partitioning rib 613 serves as a part of a side edge of the water outlet 611, so that when the condensate water is discharged at the water outlet 611, the condensate water can smoothly flow downward along a side wall of the partitioning rib 613 and drip downward from a bottom end of the partitioning rib 613.

As shown in FIG. 33, in some embodiments, at the water outlet 611, a bottom surface of one end of the partitioning rib 613 away from the flanged rib 621 is recessed with a water-blocking groove 616. One side of the water-blocking groove 616 close to the flanged rib 621 is formed with a water guiding slope 6161. The water guiding slope 6161 is disposed to be inclined downward toward a direction close to the flanged rib 621. In this way, by cooperation of the water-blocking groove 616 and the water guiding slope 6161, a width of the water-blocking groove 616 gradually increases in a top-to-bottom direction. When the condensate water is discharged at the water outlet 611, the condensate water can smoothly flow downward along the water guiding slope 6161 toward the side close to the flanged rib 621, and only a small part of the condensate water will cross the water-blocking groove 616 and flow downward from a groove wall of the water-blocking groove 616 away from the water guiding slope 6161. Therefore, the condensate water is concentrated on one side of the flanged rib 621 to flow downward, improving the drainage smoothness of the water outlet 611.

It should be noted that, in some embodiments, the water guiding slope 6161 is a flat inclined surface structure, or the water guiding slope 6161 is also a smooth arc-shaped surface structure.

As shown in FIG. 32, FIG. 33, and FIG. 34, in some embodiments, the first water receiving tray 6 is provided with a water collection area 63. The water collection area 63 is disposed on the top surface of the first water receiving tray 6. The water collection area 63 is disposed in a region other than the first water receiving groove 61. The water collection area 63 is disposed below an outer wall of the indoor fan assembly 4. Condensate water on the outer wall of the indoor fan assembly 4 flows downward into the water collection area 63 and is collected in the water collection area 63.

As shown in FIG. 32, FIG. 33, and FIG. 34, in some embodiments, the water collection area 63 is in communication with the first water receiving groove 61. A connection channel 64 is provided between the water collection area 63 and the first water receiving groove 61. One end of the connection channel 64 is in communication with the water collection area 63. The other end of the connection channel 64 is in communication with the first water receiving groove 61. In this way, the condensate water in the water collection area 63 enters the first water receiving groove 61 through the connection channel 64 and is discharged downward through the water outlet 611.

As shown in FIG. 32, FIG. 33, and FIG. 34, in some embodiments, the connection channel 64 is provided between the water outlet end 610 of the first water receiving groove 61 and the water collection area 63. One end of the connection channel 64 is in communication with the water collection area 63. The other end of the connection channel 64 is in communication with any water outlet 611 of the water outlet end 610. Since the condensate water on the outer wall of the indoor fan assembly 4 is less than the condensate water on the indoor heat exchanger 23, the condensate water in the water collection area 63 will be significantly less than the condensate water in the first water receiving groove 61. The water collection area 63 is in communication with any water outlet 611 through the connection channel 64, so that the condensate water in the water collection area 63 can be discharged through the connection channel 64 and the water outlet 611, ensuring the drainage efficiency of the water collection area 63.

It should be noted that, in other embodiments, one end of the water collection area 63 is also in communication with any plurality of the water outlets 611.

As shown in FIG. 35 and FIG. 36, in some embodiments, the indoor heat exchanger 23 has an outlet pipe 231. The outlet pipe 231 is disposed along a top-to-bottom direction. An outlet end of the indoor heat exchanger 23 is in communication with an upper end of the outlet pipe 231. A lower end of the outlet pipe 231 extends to below the first water receiving tray 6, so as to be in communication with an inlet of the compressor 21.

As shown in FIG. 35 and FIG. 36, in some embodiments, a plurality of outlet ends of the indoor heat exchanger 23 are provided, and the plurality of outlet ends of the indoor heat exchanger 23 are converged and then in communication with the upper end of the outlet pipe 231. A number of the outlet ends of the indoor heat exchanger 23 is adjusted as needed, and is not limited herein.

As shown in FIG. 35 and FIG. 36, in some embodiments, the outlet pipe 231 comprises a first pipe section 2311. The first pipe section 2311 is located above the first water receiving tray 6. The first pipe section 2311 is disposed to extend downward from the outlet end of the indoor heat exchanger 23. In this way, condensate water generated on the first pipe section 2311 flows downward along the first pipe section 2311, and thus flows into the first water receiving tray 6 below.

As shown in FIG. 35 and FIG. 36, in some embodiments, the outlet pipe 231 comprises a second pipe section 2312. The second pipe section 2312 is disposed to extend upward and bent from a bottom end of the first pipe section 2311, so that a height of one end of the second pipe section 2312 connected to the first pipe section 2311 is lower than a height of another end of the second pipe section 2312 away from the first pipe section 2311. In this way, condensate water generated on the second pipe section 2312 flows downward along the second pipe section 2312, flows to the one end of the second pipe section 2312 connected to the first pipe section 2311, and then drips downward from a connection between the first pipe section 2311 and the second pipe section 2312, thereby flowing into the first water receiving tray 6 below.

As shown in FIG. 35 and FIG. 36, in some embodiments, a bent connection between the first pipe section 2311 and the second pipe section 2312 is formed with a bent portion 2313. The bent portion 2313 is located at a bottom end of the second pipe section 2312. In this way, the bent portion 2313 is located at the one end of the second pipe section 2312 connected to the first pipe section 2311, and the another end of the second pipe section 2312 away from the first pipe section 2311 is a top end of the second pipe section 2312. The condensate water generated on the second pipe section 2312 flows downward along an outer wall of the second pipe section 2312, flows to the bent portion 2313 and drips downward, thereby flowing into the first water receiving tray 6 below. In addition, the condensate water generated on the first pipe section 2311 flows downward along an outer wall of the first pipe section 2311, flows to the bent portion 2313 and drips downward, thereby flowing into the first water receiving tray 6 below.

As shown in FIG. 35 and FIG. 36, in some embodiments, the first pipe section 2311 and the second pipe section 2312 are respectively a straight pipe structure. The first pipe section 2311 is a straight pipe structure extending vertically up and down. The second pipe section 2312 is a straight pipe structure extending obliquely up and down. The bottom end of the first pipe section 2311 and the bottom end of the second pipe section 2312 are bent and connected by the bent portion 2313.

As shown in FIG. 35 and FIG. 36, in some embodiments, the outlet pipe 231 comprises a third pipe section 2314. The third pipe section 2314 is disposed to extend downward from the another end of the second pipe section 2312 away from the bent portion 2313. Condensate water generated on the third pipe section 2314 flows downward along an outer wall of the third pipe section 2314, thereby facilitating flowing into the water collection groove of the chassis 12.

As shown in FIG. 35 and FIG. 36, in some embodiments, an outer wall of the indoor fan assembly 4 protrudes with a water blocking portion 411. The water blocking portion 411 is disposed below the bent portion 2313. In this way, the condensate water generated on the first pipe section 2311 and the second pipe section 2312 respectively flows downward along outer walls to the bent portion 2313, drips downward from a bottom end of the bent portion 2313 onto the water blocking portion 411, flows to the outer wall of the indoor fan assembly 4 through the water blocking portion 411, and then flows downward to the first water receiving tray 6 through the outer wall of the indoor fan assembly 4, thereby preventing the condensate water on the outlet pipe 231 from dripping directly into the first water receiving tray 6, and thus preventing the condensate water from splashing out of the water receiving tray and splashing onto an inner wall of the housing 1, and dripping to the ground surface along the inner wall of the housing 1, and effectively solving a problem that the condensate water of the outlet pipe 231 easily splashes out of the water receiving tray.

As shown in FIG. 35 and FIG. 37, in some embodiments, a vertical distance L between the water blocking portion 411 and the bottom end of the bent portion 2313 is less than 50 mm. In this way, by the vertical distance L between the water blocking portion 411 and the bottom end of the bent portion 2313 being less than 50 mm, a height difference between the water blocking portion 411 and the bottom end of the bent portion 2313 is reduced, which effectively prevents the condensate water dripping from the bottom end of the bent portion 2313 from splashing on the water blocking portion 411, thereby preventing the condensate water on the water blocking portion 411 from splashing onto the inner wall of the housing 1.

It should be noted that the water blocking portion 411 is also in contact with the bottom end of the bent portion 2313. At this time, the vertical distance between the water blocking portion 411 and the bottom end of the bent portion 2313 is zero. At this time, the condensate water at the bottom end of the bent portion 2313 flows directly to the water blocking portion 411.

As shown in FIG. 35, FIG. 36, and FIG. 37, in some embodiments, a top surface of the water blocking portion 411 is formed with a water blocking slope 4111. The bent portion 2313 is disposed above the water blocking slope 4111. The water blocking slope 4111 is disposed to extend obliquely downward toward a direction close to the indoor fan assembly 4. In this way, when the condensate water on the bent portion 2313 drips onto the water blocking slope 4111, the condensate water flows downward along the water blocking slope 4111 toward the direction close to the indoor fan assembly 4 and flows to an outer side wall of the indoor fan assembly 4, and thus can smoothly flow downward to the first water receiving tray 6 along the outer side wall of the indoor fan assembly 4.

As shown in FIG. 35, FIG. 36, and FIG. 37, in some embodiments, a top of the water blocking portion 411 is provided with a stepped portion 4112. The stepped portion 4112 is located at one end of the water blocking slope 4111 away from the indoor fan assembly 4. There is a height difference between the stepped portion 4112 and a top side edge of the water blocking slope 4111. The stepped portion 4112 is higher than the top side edge of the water blocking slope 4111. In this way, when the condensate water on the bent portion 2313 drips onto the water blocking slope 4111, a portion of splashed water is blocked by the stepped portion 4112 and flows back to the water blocking slope 4111 along a side wall of the stepped portion 4112, thereby preventing the condensate water dripping on the water blocking slope 4111 from splashing onto the inner wall of the housing 1.

As shown in FIG. 35 and FIG. 36, in some embodiments, a water blocking rib 4113 disposed to extend upward is disposed at a side edge of the water blocking slope 4111 away from the indoor heat exchanger 23. The water blocking rib 4113 is disposed to extend obliquely downward along the side edge of the water blocking slope 4111. A bottom end of the water blocking rib 4113 is connected to the outer wall of the indoor fan assembly 4. A top end of the water blocking rib 4113 is connected to the stepped portion 4112. In this way, the water blocking rib 4113 provides shielding at the side edge of the water blocking slope 4111 away from the indoor heat exchanger 23. When the condensate water on the bent portion 2313 drips onto the water blocking slope 4111, a portion of splashed water is blocked by the water blocking rib 4113 and flows back to the water blocking slope 4111 along a side wall of the water blocking rib 4113, thereby preventing the condensate water dripping on the water blocking slope 4111 from splashing onto the inner wall of the housing 1.

It should be noted that, in some embodiments, when the condensate water on the bent portion 2313 drips onto the water blocking slope 4111, water splashed toward a side close to the indoor heat exchanger 23 flows downward along the outer wall of the indoor heat exchanger 23, and thus flows to the first water receiving tray 6; water splashed toward a side away from the indoor heat exchanger 23 is blocked by the water blocking rib 4113 and flows back to the water blocking slope 4111; water splashed toward a side close to the indoor fan assembly 4 flows downward along the outer wall of the indoor fan assembly 4, and thus flows to the first water receiving tray 6; and water splashed toward a side away from the indoor fan assembly 4 is blocked by the stepped portion 4112 and flows back to the water blocking slope 4111. In this way, the water blocking slope 4111 can, to a certain extent, prevent the condensate water splashed on the water blocking slope 4111 from splashing onto the housing 1.

As shown in FIG. 36 and FIG. 38, in some embodiments, the indoor fan assembly 4 comprises an indoor air duct shell 41. An indoor air duct is formed in an interior of the indoor air duct shell 41. The indoor air duct shell 41 is disposed on one side of the indoor heat exchanger 23 in the horizontal direction. The indoor heat exchanger 23 is attached to an outer wall of the indoor air duct shell 41. An air inlet end of the indoor air duct shell 41 faces the indoor heat exchanger 23, and thus faces the indoor air inlet 111. An air outlet end of the indoor air duct shell 41 faces the indoor air outlet 112. In this way, when the indoor fan assembly 4 is in operation, the indoor fan assembly 4 can draw the indoor air into the interior of the housing 1 through the indoor air inlet 111 to perform heat exchange with the indoor heat exchanger 23, and the air after heat exchange can enter an interior of the indoor air duct shell 41 and be discharged again to the indoor space outside the housing 1 through the air outlet end of the indoor air duct shell 41 and the indoor air outlet 112.

As shown in FIG. 36 and FIG. 38, in some embodiments, a bottom end of the indoor air duct shell 41 is installed on the first water receiving tray 6. The water blocking portion 411 is disposed on the outer wall of the indoor air duct shell 41. In this way, when the condensate water on the outlet pipe 231 of the indoor heat exchanger 23 drips onto the water blocking portion 411, the condensate water can flow to the outer side wall of the indoor air duct shell 41 along the water blocking portion 411, and flow downward along the outer side wall of the indoor air duct shell 41 to flow into the first water receiving tray 6 from a bottom end of the indoor air duct shell 41, thereby effectively preventing the condensate water from dripping from a height and splashing onto the inner wall of the housing 1.

As shown in FIG. 36 and FIG. 38, in some embodiments, the indoor fan assembly 4 comprises an indoor fan wheel 42. The indoor fan wheel 42 is rotatably disposed in the interior of the indoor air duct shell 41, that is, the indoor fan wheel 42 is rotatably disposed in the indoor air duct. When the indoor fan wheel 42 rotates, a wind force is formed in the interior of the indoor air duct shell 41, so that air from the indoor space can flow through the indoor air outlet 112, flow through the indoor heat exchanger 23, enter the interior of the indoor air duct shell 41, and then be discharged to the indoor space outside the housing 1 through the air outlet end of the indoor air duct shell 41 and the indoor air outlet 112.

As shown in FIG. 36 and FIG. 38, in some embodiments, the indoor fan assembly 4 comprises an indoor electric motor 43. An output end of the indoor electric motor 43 is in transmission connection with the indoor fan wheel 42. The indoor electric motor 43 is used for driving the indoor fan wheel 42 to rotate in the interior of the indoor air duct shell 41. When the indoor electric motor 43 drives the indoor fan wheel 42 to rotate in the interior of the indoor air duct shell 41, a wind force is formed in the interior of the indoor air duct shell 41, so that air from the indoor space can flow through the indoor air outlet 112, flow through the indoor heat exchanger 23, enter the interior of the indoor air duct shell 41, and then be discharged to the indoor space outside the housing 1 through the air outlet end of the indoor air duct shell 41 and the indoor air outlet 112.

As shown in FIG. 36 and FIG. 38, in some embodiments, the indoor air duct shell 41 and the indoor fan wheel 42 are respectively disposed to extend along the vertical direction. The indoor electric motor 43 is disposed below a bottom of the indoor air duct shell 41 and is provided above the first water receiving tray 6. In this way, a horizontal size width of the air conditioner is reduced, and a longitudinal size height of the air conditioner is increased, which is conducive to reducing the occupation of the indoor space by the air conditioner.

As shown in FIG. 30 and FIG. 38, in some embodiments, the first water receiving tray 6 is provided with a mounting area 65. The first water receiving groove 61 is disposed on one side of the mounting area 65. The bottom end of the indoor air duct shell 41 is installed in the mounting area 65. The first end 61a of the first water receiving groove 61 is disposed on one side of the mounting area 65, and the second end 61b of the first water receiving groove 61 is disposed to extend bent on an adjacent side of the mounting area 65. The indoor heat exchanger 23 in the horizontal direction extends from the first end 61a of the first water receiving groove 61 to the second end 61b of the first water receiving groove 61, so that the indoor heat exchanger 23 is disposed on adjacent sides of the indoor air duct shell 41 in the horizontal direction. At this time, the air inlet end of the indoor air duct shell 41 is disposed on the adjacent sides of the indoor air duct shell 41 in the horizontal direction, and thus is disposed to face the indoor heat exchanger 23, which is conducive to an air intake efficiency of the indoor fan assembly 4 and improves the heat exchange efficiency of the indoor heat exchanger 23.

As shown in FIG. 30 and FIG. 38, in some embodiments, the first water receiving tray 6 is provided with a mounting position 651. The mounting position 651 is located in the mounting area 65. The indoor electric motor 43 is installed in the mounting position 651. The mounting position 651 is isolated from the first water receiving groove 61 and the water collection area 63, thereby preventing the condensate water in the first water receiving groove 61 and the water collection area 63 from entering the mounting position 651, and preventing the condensate water from entering the indoor electric motor 43 and affecting normal operation of the indoor electric motor 43.

As shown in FIG. 3 and FIG. 4, in some embodiments, a fixing rod 114 is disposed in the housing 1. The fixing rod 114 is disposed inside the main shell 11. The fixing rod 114 is disposed to extend along the vertical direction.

As shown in FIG. 3 and FIG. 35, the water blocking portion 411 is fixed on the fixing rod 114. In this way, one side of the outdoor air duct shell 30 is fixed on the fixing rod 114 through the water blocking portion 411, thereby improving structural stability of the water blocking portion 411 and the outdoor air duct shell 30.

The air conditioner of the embodiments of the present disclosure is also used for solving a problem of a water discharge efficiency of a water receiving tray. In a related air conditioner, the water discharge efficiency of the water receiving tray inside the air conditioner is low, water in the water receiving tray flows to a water outlet at a slow speed, and the water in the water receiving tray easily accumulates and cannot be discharged in time, which will affect working of a heat exchanger and even cause water leakage of the air conditioner.

To solve the foregoing problem, as shown in FIG. 39 and FIG. 40, in an air conditioner of an embodiment of the present disclosure operating independently, the air conditioner is provided with a compressor 21, an expansion valve, an outdoor heat exchanger 22, an indoor heat exchanger 23, an outdoor air duct shell 30, an outdoor fan 310, an indoor air duct shell 40, and an indoor fan 410.

As shown in FIG. 39, in some embodiments, the outdoor fan 310 is disposed in the outdoor air duct shell 30, and the outdoor air duct shell 30 defines a flow path of air inside the outdoor air duct shell 30. Operation of the outdoor fan 310 can introduce air into the housing 1 through the outdoor air duct shell 30, and form a heat exchange air flow through heat exchange with a refrigerant in the outdoor heat exchanger 22.

As shown in FIG. 40, in some embodiments, the indoor fan 410 is disposed in the indoor air duct shell 40, and the indoor air duct shell 40 defines a flow path of air inside the indoor air duct shell 40. Operation of the indoor fan 410 can introduce air into the housing 1 through the indoor air duct shell 40, and form a heat exchange air flow through heat exchange with a refrigerant in the indoor heat exchanger 23.

The outdoor heat exchanger 22 is an evaporator or a condenser, and correspondingly the indoor heat exchanger 23 is a condenser or an evaporator. The air conditioner executes the refrigerating cycle or the heating cycle of the air conditioner by using the compressor 21, the expansion valve, the condenser, and the evaporator.

As shown in FIG. 39 and FIG. 40, the housing 1 comprises a main shell 11 and a chassis 12, the main shell 11 and the chassis 12 form an internal accommodating space 10, which is suitable for providing a refrigerant circuit 20 of the air conditioner, and can provide a stable and reliable setting position for the refrigerant circuit 20 in the air conditioner. The refrigerant circuit 20 comprises a compressor 21, an outdoor heat exchanger 22, and an indoor heat exchanger 23 connected end to end, which allows a refrigerant to form a flow circuit among the compressor 21, the outdoor heat exchanger 22, and the indoor heat exchanger 23.

With reference to FIG. 39 and FIG. 40, in some embodiments, an air inlet pipe 14 and an air outlet pipe 15 are provided outside the accommodating space 10 of the housing 1. After outdoor air enters the accommodating space 10 through the air inlet pipe 14, the outdoor air first undergoes heat exchange with the outdoor heat exchanger 22, then enters the outdoor air duct shell 30, flows out of the outdoor air duct shell 30 to the air outlet pipe 15 under an acceleration action of the outdoor fan 310, and then flows to the outdoors from the air outlet pipe 15.

With reference to FIG. 41, FIG. 42, and FIG. 43, in some embodiments, the air conditioner further comprises a first water receiving tray 6, and the first water receiving tray 6 is disposed in the accommodating space 10. The first water receiving tray 6 is connected to the main shell 11. The first water receiving tray 6 is located below the indoor heat exchanger 23 and is used for receiving condensate water formed by heat exchange between the indoor heat exchanger 23 and indoor air. The outdoor heat exchanger 22 is located below the first water receiving tray 6. The first water receiving tray 6 is provided with a first water receiving groove 61 and a first water outlet 601, and the first water receiving groove 61 and the first water outlet 601 are in communication with each other. Specifically, when the indoor heat exchanger 23 performs heat exchange, condensate water will be condensed on a surface of the indoor heat exchanger 23, and the first water receiving tray 6 is disposed below the indoor heat exchanger 23. The condensate water will flow to the first water receiving groove 61 of the first water receiving tray 6 under an action of gravity, and flow out to the first water outlet 601 through a water outlet end of the first water receiving groove 61, and finally flow out from the first water outlet 601 to an exterior, thereby achieving discharge of the condensate water in the first water receiving tray 6.

With reference to FIG. 42 and FIG. 43, in some embodiments, the first water outlet 601 and the water outlet end of the first water receiving groove 61 are spacedly disposed, a plurality of partitioning ribs 613 are provided between the first water outlet 601 and the water outlet end of the first water receiving groove 61, and a water guiding channel 614 is formed between two adjacent partitioning ribs 613. The first water outlet 601 and the water guiding channel 614 are both plural in number. Water inlet ends of the plurality of water guiding channels 614 are in communication with the water outlet end of the first water receiving groove 61, and water outlet ends of the plurality of water guiding channels 614 are in one-to-one corresponding communication with the plurality of first water outlets 601. Specifically, by spacedly arranging the first water outlet 601 and the water outlet end of the first water receiving groove 61, and providing the plurality of partitioning ribs 613 between the first water outlet 601 and the water outlet end of the first water receiving groove 61, a water guiding channel 614 is defined between the two adjacent partitioning ribs 613, and there are a plurality of the water guiding channels 614.

By putting the plurality of water guiding channels 614 and the plurality of first water outlets 601 in one-to-one corresponding communication, the condensate water can enter the plurality of water guiding channels 614 after flowing out from the water outlet end of the first water receiving groove 61, and enter the plurality of first water outlets 601 through the plurality of water guiding channels 614, so that the condensate water flows out from the plurality of first water outlets 601. With such a setting, the plurality of first water outlets 601 can increase a water discharge amount of the first water receiving tray 6 per unit time, and the plurality of water guiding channels 614 can improve a smoothness of the condensate water flow, thereby improving the water discharge efficiency of the first water receiving tray 6.

Thus, a plurality of water guiding channels 614 are defined by a plurality of partitioning ribs 613, and the plurality of water guiding channels 614 correspond to a plurality of first water outlets 601 one-to-one. Therefore, water flowing out from a water outlet end of the first water receiving groove 61 is guided to the plurality of first water outlets 601 through the plurality of water guiding channels 614, which can increase the water discharge amount of the first water receiving tray 6 per unit time, and can improve a smoothness of water discharge, thereby improving the water discharge efficiency of the first water receiving tray 6.

With reference to FIG. 42 and FIG. 43, in some embodiments, a water guiding slope 6161 is provided between the first water outlet 601 and the water outlet end of the first water receiving groove 61, a plurality of partitioning ribs 613 are disposed on the water guiding slope 6161, the water guiding slope 6161 is disposed to be inclined from top to bottom, and the first water outlet 601 is disposed at a lower end of the water guiding slope 6161.

As shown in FIG. 43, in some embodiments, by providing the water guiding slope 6161 between the first water outlet 601 and the water outlet end of the first water receiving groove 61, providing the plurality of partitioning ribs 613 in the water guiding slope 6161, and arranging the water guiding slope 6161 to be inclined in a downward direction. After the condensate water flows out from the water outlet end of the first water receiving groove 61 into the water guiding channel 614, due to the inclined setting of the water guiding slope 6161, a water flow will be continuously accelerated under the action of gravity. Therefore, a speed of the water flow in the water guiding channel 614 can be gradually increased, and the water flow can quickly flow to the first water outlet 601 and flow out from the first water outlet 601, which can further improve the water discharge efficiency of the first water receiving tray 6.

With reference to FIG. 42 and FIG. 43, in some embodiments, the first water receiving tray 6 is provided with a second water outlet 602, and the second water outlet 602 is spacedly disposed on an outer side of the plurality of partitioning ribs 613. Specifically, by providing the second water outlet 602 on the first water receiving tray 6, when too much water flows from the water guiding channel 614 to the first water outlet 601 and cannot be discharged by the first water outlet 601 in time, the water flow will overflow to the outer side of the plurality of partitioning ribs 613, thereby entering the second water outlet 602 and flowing out from the second water outlet 602. This can further improve reliability of drainage of the first water receiving tray 6 and can optimize a structural design of the first water receiving tray 6.

With reference to FIG. 42 and FIG. 43, in some embodiments, the water receiving tray has a first water receiving groove 61, a water guiding slope 6161 is located on one side of the first water receiving groove 61, a first water outlet 601 is located at a bottom of the first water receiving groove 61, and a second water outlet 602 is also located at the bottom of the first water receiving groove 61. A plurality of partitioning ribs 613 are disposed on the water guiding slope 6161. After excess water flows into the first water receiving groove 61 through the water guiding slope 6161 and cannot be discharged by the first water outlet 601 in time. A water level will be higher than a height of the plurality of partitioning ribs 613, so that the water overflows from the plurality of partitioning ribs 613, and flows to the second water outlet 602 also located at the bottom of the first water receiving groove 61, and flows out from the second water outlet 602.

With reference to FIG. 42 and FIG. 43, a caliber of the second water outlet 602 is larger than a caliber of the first water outlet 601.

With reference to FIG. 42 and FIG. 43, there is one second water outlet 602, and the caliber of the second water outlet 602 is set to be larger than the caliber of a single first water outlet 601. On the premise of facilitating manufacturing of the first water receiving tray 6, a water discharge efficiency of the second water outlet 602 can be improved, thereby further improving the water discharge efficiency of the first water receiving tray 6.

As shown in FIG. 41, in some embodiments, the air conditioner further comprises a second water receiving tray 5. The second water receiving tray 5 is located below the outdoor heat exchanger 22, and the compressor 21 is located below the second water receiving tray 5.

As shown in FIG. 41, in some embodiments, the air conditioner further comprises a water splashing device 510. The water splashing device 510 comprises a water splashing wheel 54 and a water splashing driving member 55, the water splashing wheel 54 is rotatably disposed on the second water receiving tray 5, and the water splashing driving member 55 is disposed on the second water receiving tray 5 and is in transmission connection with the water splashing wheel 54.

As shown in FIG. 41, in some embodiments, the outdoor heat exchanger 22 comprises a first heat exchange part 221 and a second heat exchange part 222. The first heat exchange part 221 and the second heat exchange part 222 are spacedly disposed to form a water flow channel 24, and the water splashing wheel 54 is correspondingly disposed at a lower end of the water flow channel 24. Specifically, by providing the second water receiving tray 5 below the outdoor heat exchanger 22, condensate water is generated on a surface of the outdoor heat exchanger 22 during a heat exchange process, and the condensate water flows to the second water receiving tray 5 under the action of gravity. By providing the water splashing wheel 54 and the water splashing driving member 55 on the second water receiving tray 5, and causing the water splashing driving member 55 to drive the water splashing wheel 54 to rotate, the rotation of the water splashing wheel 54 can splash up water in the second water receiving tray 5, and cause the water to cool the surface of the indoor heat exchanger 23. In this way, on the one hand, self-treatment of the water in the second water receiving tray 5 can be achieved, and on the other hand, the heat exchange efficiency of the indoor heat exchanger 23 can also be improved.

In addition, by spacedly arranging the first heat exchange part 221 and the second heat exchange part 222 to form the water flow channel 24, water on the outdoor heat exchanger 22 can flow to the water splashing wheel 54 through the water flow channel 24, and water on the first water receiving tray 6 can also flow to the water splashing wheel 54 through the water flow channel 24 after flowing out from the first water outlet 601. This not only ensures a smoothness of the water on the outdoor heat exchanger 22 flowing to the second water receiving tray 5, but also ensures a smoothness of the water on the first water receiving tray 6 flowing to the second water receiving tray 5.

It should be noted that when the outdoor heat exchanger 22 is a condenser, the first heat exchange part 221 is a one-row condenser, and the second heat exchange part 222 is a three-row condenser. In this way, the heat exchange efficiency of the outdoor heat exchanger 22 can be ensured on the premise of ensuring that the water flow channel 24 is smooth.

With reference to FIG. 44 and FIG. 45, in some embodiments, the air conditioner further comprises a sealing plate 66. The sealing plate 66 is provided to cover an upper side of the outdoor heat exchanger 22, the sealing plate 66 is provided with a guiding groove 661, and the guiding groove 661 is in corresponding communication with the water flow channel 24. Specifically, the sealing plate 66 is provided to cover the upper side of the outdoor heat exchanger 22, the sealing plate 66 is provided with the guiding groove 661, and the guiding groove 661 corresponds to the water flow channel 24. On the one hand, the sealing plate 66 can protect the upper side of the outdoor heat exchanger 22 together with the first water receiving tray 6. On the other hand, since the sealing plate 66 is relatively close to the outdoor heat exchanger 22, condensate water will also be condensed on a surface of the sealing plate 66. Therefore, by providing the guiding groove 661 on the sealing plate 66, the condensate water can flow to the water flow channel 24 under an action of gravity and a guiding action of the guiding groove 661. Thus the condensate water flows to the second water receiving tray 5 through the water flow channel 24, which can further optimize a structural performance of the air conditioner.

With reference to FIG. 44 and FIG. 45, in some embodiments, a cross-section of the guiding groove 661 in an up-down direction is an inverted V-shape, and in a top-to-bottom direction, a cross-sectional area of the guiding groove 661 in a horizontal direction gradually increases. Specifically, by setting the cross-section of the guiding groove 661 in the up-down direction to be the inverted V-shape, in the top-to-bottom direction, the cross-sectional area of the guiding groove 661 in the horizontal direction gradually increases. This allows the guiding groove 661 to guide the condensate water more stably and smoothly, and allows the condensate water to flow to the water flow channel 24 more uniformly, which can further improve a flow guiding effect of the guiding groove 661 and can optimize a structural design of the sealing plate 66.

With reference to FIG. 44 and FIG. 45, in some embodiments, an inner wall of the guiding groove 661 is provided with a plurality of guiding ribs 662, and a guiding channel 663 is formed between two adjacent guiding ribs 662. There are a plurality of the guiding channels 663, and the plurality of guiding channels 663 are all in corresponding communication with the water flow channel 24. Specifically, by providing the plurality of guiding ribs 662 in the guiding groove 661, and forming the guiding channel 663 between the two adjacent guiding ribs 662, not only can the guiding groove 661 guide the condensate water more stably and smoothly, but also a structure of the guiding groove 661 can be simplified, thereby further optimizing the structural design of the sealing plate 66.

As shown in FIG. 44, in some embodiments, the sealing plate 66 and the first water receiving tray 6 are an integrally formed structural part. Specifically, by setting the sealing plate 66 and the first water receiving tray 6 as an integrally formed structural part, not only can mounting steps of the sealing plate 66 and the first water receiving tray 6 in the accommodating space 10 be simplified, but also stability of a connection between the sealing plate 66 and the first water receiving tray 6 can be improved, thereby improving the structural reliability of the air conditioner.

As shown in FIG. 44, in other embodiments, the sealing plate 66 and the first water receiving tray 6 are detachably connected. Specifically, by detachably connecting the sealing plate 66 and the first water receiving tray 6, separate maintenance and replacement of the sealing plate 66 and the first water receiving tray 6 are facilitated on the premise of ensuring that the connection between the sealing plate 66 and the first water receiving tray 6 is stable.
