Technical Field

[0002] This disclosure relates to the field of air conditioning technology, and in particular to an air conditioner. Background Technology

[0003] An air conditioner typically consists of main components such as a compressor, an outdoor heat exchanger, an indoor heat exchanger, and a fan. The compressor drives the refrigerant circulation, the outdoor and indoor heat exchangers act as condensers and evaporators for heat release and absorption, respectively, and the fan accelerates airflow to enhance heat exchange efficiency. Summary of the Invention

[0004] This invention aims to solve the problem of rainwater entering air conditioners.

[0005] This disclosure provides an air conditioner comprising: a housing forming the outer casing of the air conditioner; a receiving space within the housing; a refrigerant circulation loop disposed within the receiving space, the refrigerant circulation loop including a compressor, an outdoor heat exchanger, and an indoor heat exchanger connected end-to-end; an air inlet duct disposed outside the housing for introducing outdoor air; an outdoor duct housing with its air inlet end connected to the air inlet duct and connected to the outside via the air inlet duct, and its air outlet end facing the outdoor heat exchanger; wherein, a drain hole is provided on the inner bottom surface of the outdoor duct housing, and a water guiding structure is provided below the drain hole; a water collection tank is provided within the receiving space, the water collection tank being disposed below the water guiding structure; water in the outdoor duct housing can be discharged downward through the drain hole and flow into the water collection tank via the water guiding structure.

[0006] The above-described technical solution utilizes the outdoor heat exchanger and indoor heat exchanger, which can serve as the condenser and evaporator respectively. The refrigerant absorbs heat during evaporation in the evaporator and releases heat during condensation in the condenser, thus executing the air conditioner's cooling or heating cycle. During storms or heavy rain, rainwater easily enters the air conditioner through the air inlet duct and then into the outdoor duct casing. Drainage holes on the inner bottom surface of the outdoor duct casing, along with a water-guiding structure below the drainage holes, allow rainwater entering the outdoor duct casing to drain downwards through the drainage holes and flow into a collection tank through the water-guiding structure, preventing rainwater from flowing directly to the ground and effectively solving the problem of rainwater entering the air conditioner through the air inlet duct.

[0052] The following description, in conjunction with the accompanying drawings, clearly and completely describes some embodiments of this disclosure. Obviously, the described embodiments are merely some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0053] In air conditioners, there is usually an air inlet duct that connects to the outside. During strong winds and heavy rain, rainwater can easily enter the air conditioner through the air inlet duct and flow down the outer casing to the ground, causing customer complaints.

[0054] To address the aforementioned problems, as shown in Figure 1, some embodiments of this disclosure provide an air conditioner that may include a housing 1. The housing 1 may be configured as the outer casing of the air conditioner. The interior of the housing 1 may be used to provide installation space.

[0055] In some embodiments, the housing 1 may adopt a hollow cuboid structure. The length of the housing 1 may be arranged along the height direction, so that the air conditioner can be installed vertically in the usage site, thereby increasing the height of the air conditioner and reducing the space occupied by the air conditioner.

[0056] As shown in Figures 1 and 2, in some embodiments, the housing 1 may include a main housing 11. The main housing 11 may extend along the height direction. The height dimension of the main housing 11 may be greater than the left-right width dimension and the front-back width dimension of the main housing 11, so as to increase the height of the housing 1 and reduce the space occupied by the housing 1.

[0057] As shown in Figures 1 and 3, in some embodiments, the housing 1 may include a chassis 12. The chassis 12 is located at the bottom of the main housing 11. A receiving space 10 may be formed between the top of the chassis 12 and the interior of the main housing 11. This receiving space 10 is used as a mounting space for other components of the air conditioner.

[0058] As shown in Figures 1 and 3, in some embodiments, the chassis 12 may be provided with feet 13 on its periphery. The feet 13 may extend outward from the chassis 12, and the feet 13 may be used to increase the contact area between the bottom of the casing 1 and the ground, thereby improving the reliability of the chassis 12 in supporting the air conditioner and improving the stability of the air conditioner.

[0059] As shown in Figures 1 and 3, in some embodiments, multiple feet 13 can be provided, and the multiple feet 13 can be connected end to end, so that the multiple feet 13 are arranged circumferentially around the periphery of the chassis 12. In this way, the multiple feet 13 can form a ring structure on the outer periphery of the chassis 12, which improves the structural strength between the multiple feet 13 and forms a complete ring structure; at the same time, it avoids the feet 13 from bumping into the user and improves the safety of the air conditioner.

[0060] As shown in Figures 3 and 4, in some embodiments, the air conditioner may include a refrigerant circulation loop. The refrigerant circulation loop may be located within the casing 1. The refrigerant circulation loop may be located within the accommodating space 10. The refrigerant circulation loop may include a compressor 21, an outdoor heat exchanger 22, and an indoor heat exchanger 23 connected end-to-end. The refrigerant circulates within the refrigerant circulation loop formed by the compressor 21, the outdoor heat exchanger 22, and the indoor heat exchanger 23. During the refrigerant circulation process, the outdoor heat exchanger 22 and the indoor heat exchanger 23 can respectively function as a condenser and an evaporator, allowing the refrigerant to absorb heat through evaporation in the evaporator and release heat through condensation in the condenser, thereby executing either a cooling cycle or a heating cycle for the air conditioner.

[0061] Specifically, in the refrigeration cycle, the outdoor heat exchanger 22 can act as a condenser, and the indoor heat exchanger 23 can act as an evaporator. In the heating cycle, the outdoor heat exchanger 22 can act as an evaporator, and the indoor heat exchanger 23 can act as a condenser.

[0062] It should be noted that both the refrigeration and heating cycles involve a series of processes, including compression, condensation, expansion, and evaporation, and the supply of refrigerant to the conditioned and heat-exchanged air.

[0063] Compressor 21 is used to compress refrigerant gas and discharge the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser.

[0064] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0065] The evaporator evaporates the expanded refrigerant and returns the refrigerant gas, now at a low temperature and low pressure, to the compressor 21. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the surrounding environment.

[0066] Throughout the cycle, the air conditioner can regulate the temperature of the indoor space, improve the comfort of the indoor space, and enhance the user experience.

[0067] As shown in Figures 2, 3, and 4, in some embodiments, the air conditioner may include an outdoor fan assembly 3. The outdoor fan assembly 3 may be arranged opposite to the outdoor heat exchanger 22. The outdoor fan assembly 3 can be used to introduce outdoor air into the casing 1 for heat exchange with the outdoor heat exchanger 22, forming a heat exchange airflow.

[0068] For example, during the cooling cycle, the outdoor heat exchanger 22 acts as a condenser, and the outdoor fan assembly 3 can draw in outside air and blow it onto the outdoor heat exchanger 22 to dissipate heat and lower its temperature. During the heating cycle, the outdoor heat exchanger 22 acts as an evaporator, and the outdoor fan assembly 3 can draw in outside air and blow it onto the outdoor heat exchanger 22 to raise its temperature.

[0069] As shown in Figures 1, 2, and 3, in some embodiments, the air conditioner may include an indoor fan assembly 4. The indoor fan assembly 4 may be arranged opposite to the indoor heat exchanger 23. The indoor fan assembly 4 can be used to introduce indoor air into the casing 1 for heat exchange with the indoor heat exchanger 23, forming a heat exchange airflow.

[0070] For example, during the refrigeration cycle, the indoor heat exchanger 23 acts as an evaporator, and the indoor fan assembly 4 can draw indoor air from outside the casing 1 and blow it towards the indoor heat exchanger 23 to exchange heat with it, thereby reducing the temperature of the air flowing through the indoor heat exchanger 23 and blowing the cooled air back into the room to lower the indoor air temperature.

[0071] For example, during the heating cycle, the indoor heat exchanger 23 acts as a condenser, and the outdoor fan assembly 3 can draw indoor air from outside the casing 1 and blow it towards the indoor heat exchanger 23 to exchange heat with it, raising the temperature of the air flowing through the indoor heat exchanger 23, and then blowing the heated air back into the room to raise the indoor air temperature.

[0072] As shown in Figures 3 and 4, in some embodiments, the compressor 21, outdoor heat exchanger 22, outdoor fan assembly 3, indoor heat exchanger 23, and indoor fan assembly 4 can be respectively housed in the receiving space 10 inside the casing 1. In this way, the casing 1 can cover and protect them, preventing the erosion of foreign objects or the impact of external forces from causing structural damage, thereby improving the structural reliability of the air conditioner and ensuring that the air conditioner can work normally.

[0073] As shown in Figures 3 and 4, in some embodiments, the internal accommodating space 10 of the casing 1 may include three sub-spaces. These three sub-spaces are, from bottom to top, a first sub-space 110, a second sub-space 120, and a third sub-space 130. The compressor 21 can be housed in the first sub-space 110. The outdoor heat exchanger 22 and the outdoor fan assembly 3 can be housed in the second sub-space 120. The indoor heat exchanger 23 and the indoor fan assembly 4 can be housed in the third sub-space 130. Thus, by using three layers of sub-spaces from bottom to top, the compressor 21, outdoor heat exchanger 22, outdoor fan assembly 3, indoor heat exchanger 23, and indoor fan assembly 4 can be distributed at different heights within the casing 1, which helps to increase the overall height of the air conditioner, reduce its width and thickness, and minimize the space occupied by the air conditioner in the operating area.

[0074] As shown in Figures 2, 3, and 4, in some embodiments, an indoor air inlet 111 may be provided on the outer wall of the casing 1. The indoor air inlet 111 can connect to the outside of the casing 1. The indoor air inlet 111 can connect to the indoor space. The indoor air inlet 111 can be located on the outer wall corresponding to the third subspace 130, and the indoor air inlet 111 can be arranged opposite to the 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 running, the indoor fan assembly 4 can draw indoor air into the casing 1 through the indoor air inlet 111 to exchange heat with the indoor heat exchanger 23, and the heat-exchanged air is discharged back into the indoor space outside the casing 1 through the air outlet end of the indoor fan assembly 4.

[0075] As shown in Figures 1, 3, and 4, in some embodiments, an indoor air outlet 112 may be provided on the outer wall of the housing 1. The indoor air outlet 112 may connect to the outside of the housing 1. The indoor air outlet 112 may connect to the indoor space. The indoor air outlet 112 may be located on the outer wall corresponding to the third subspace 130, and the indoor air outlet 112 may be arranged opposite to the air outlet end of the indoor fan assembly 4. In this way, when the indoor fan assembly 4 is running, the indoor fan assembly 4 draws indoor air through the indoor air inlet 111, exchanges heat with the indoor heat exchanger 23, and then discharges it back into the indoor space outside the housing 1 through the air outlet end and indoor air outlet 112 of the indoor fan assembly 4.

[0076] As shown in Figures 1 and 3, in some embodiments, an air guide plate 113 may be provided on the outer wall of the housing 1. The air guide plate 113 is rotatably disposed at the indoor air outlet 112. Multiple air guide plates 113 may be provided, and multiple air guide plates 113 may be arranged side by side at the indoor air outlet 112. When the air guide plate 113 rotates, it can open or close the indoor air outlet 112. When the air guide plate 113 rotates to open the indoor air outlet 112, it can also change the air outlet direction of the indoor air outlet 112.

[0077] As shown in Figures 2 and 4, in some embodiments, the air conditioner may include an air inlet duct 14. The air inlet duct 14 may be located in the space outside the casing 1. The air inlet duct 14 can be used to introduce outdoor air. One end of the air inlet duct 14 can be connected to the air inlet end of the outdoor fan assembly 3. The other end of the air inlet duct 14 can be connected to the outdoor space. The air outlet end of the outdoor fan assembly 3 can be arranged towards the outdoor heat exchanger 22. Thus, the outdoor fan assembly 3 can draw air from the outdoor space through the air inlet duct 14, introduce the outdoor air into the casing 1, and blow it towards the outdoor heat exchanger 22 to heat or cool it.

[0078] As shown in Figures 2 and 4, the air conditioner may include an air outlet duct 15. The air outlet duct 15 may be located in the space outside the casing 1. The air outlet duct 15 can be used to exhaust air to the outside, so as to discharge the air inside the casing 1 to the outside. One end of the air outlet duct 15 may be connected to the internal space of the casing 1. The other end of the air outlet duct 15 may be connected to the outdoor space. In this way, when the outdoor fan assembly 3 is running, the outdoor fan assembly 3 can draw air from the outdoor space through the air inlet duct 14, so that the outdoor air is introduced into the casing 1 and blown towards the outdoor heat exchanger 22, and the air inside the casing 1 that has flowed through the outdoor heat exchanger 22 is discharged into the outdoor space through the air outlet duct 15, thereby realizing outdoor air circulation.

[0079] It should be noted that in some other embodiments, the air inlet duct 14 can also be used for exhaust, and the air outlet duct 15 can also be used for air intake. The air outlet duct 15 can introduce outdoor air into the housing 1 for heat exchange with the outdoor heat exchanger 22. The heat-exchanged air can then be transported to the outside through the air inlet duct 14 under the action of the outdoor fan assembly 3.

[0080] As shown in Figures 2 and 4, in some embodiments, the air inlet pipe 14 and the air outlet pipe 15 can be located outside the third subspace 130. A receiving area 140 can be recessed on the upper part of the housing 1 corresponding to the outer wall of the third subspace 130. The air inlet pipe 14 and the air outlet pipe 15 can be arranged within the receiving area 140, allowing them to be positioned above the second subspace 120, and above the outdoor heat exchanger 22 and the outdoor fan assembly 3.

[0081] As shown in Figures 2 and 4, in some embodiments, the air inlet duct 14 and the air outlet duct 15 can be arranged side-by-side in the receiving area 140 on the outer wall of the housing 1. The lower end of the air inlet duct 14 can communicate with the air inlet end of the outdoor fan assembly 3. The lower end of the air outlet duct 15 can communicate with the second subspace 120 inside the housing 1. The upper ends of the air inlet duct 14 and the upper ends of the air outlet duct 15 can connect to the outdoor space. During the installation of the air conditioner, the air inlet duct 14 and the air outlet duct 15 can be extended and fixed to a wall or window, thereby connecting to the outdoor space.

[0082] As shown in Figures 3 and 4, in some embodiments, the air conditioner may include a second drip tray 5. The second drip tray 5 may be located within the receiving space 10 inside the casing 1. The second drip tray 5 may be arranged in the area between the first sub-space 110 and the second sub-space 120. The outdoor heat exchanger 22 may be located above the second drip tray 5. The second drip tray 5 can be used to collect condensate flowing down the outer wall of the outdoor heat exchanger 22. When the air conditioner is in heating mode, the refrigerant can evaporate and absorb heat in the outdoor heat exchanger 22, lowering the surface temperature of the outdoor heat exchanger 22. Water vapor in the air condenses into water upon contact with the condensate, which then falls into the second drip tray 5 at the bottom of the outdoor heat exchanger 22, either collected in the second drip tray 5 or discharged through the drain outlet on the second drip tray 5. This prevents condensate from dripping onto the ground, thus preventing the air conditioner from slipping and posing a risk of slipping and falling.

[0083] As shown in Figures 3 and 4, in some embodiments, the bottom port of the air outlet duct 15 can be arranged in the space above the second water receiving tray 5. When outdoor rainwater enters the housing 1 through the air outlet duct 15, it can be collected by the second water receiving tray 5, preventing the rainwater from flowing directly to other areas inside the housing 1 or seeping out of the housing 1 and flowing to the ground.

[0084] As shown in Figures 4 and 5, in some embodiments, a first drain outlet 51 may be provided on the side wall of the second water receiving tray 5. A drain valve 52 may be provided at the first drain outlet 51. The drain valve 52 can block the first drain outlet 51. When the drain valve 52 opens the first drain outlet 51, the first drain outlet 51 can connect to the outside of the second water receiving tray 5, and the water in the second water receiving tray 5 can flow out of the outside of the second water receiving tray 5 through the first drain outlet 51.

[0085] As shown in Figures 2 and 4, the drain valve 52 can be located outside the housing 1, and the first drain port 51 can be connected to the outside of the housing 1. When the drain valve 52 opens the first drain port 51, the water in the second water receiving tray 5 can flow out to the outside of the housing 1 through the first drain port 51.

[0086] As shown in Figures 3 and 4, in some embodiments, the air conditioner may include a first drip tray 6. The first drip tray 6 may be located within the housing 1, in the receiving space 10. The first drip tray 6 may be arranged in the area between the second sub-space 120 and the third sub-space 130. The indoor heat exchanger 23 may be located above the first drip tray 6. The indoor fan assembly 4 may be located above the first drip tray 6. The first drip tray 6 can be used to collect condensate flowing down the outer wall of the indoor heat exchanger 23. When the air conditioner is cooling, the refrigerant can evaporate and absorb heat in the indoor heat exchanger 23, lowering the surface temperature of the indoor heat exchanger 23. Water vapor in the air condenses into water upon contact with the condenser, which then falls into the first drip tray 6 at the bottom of the indoor heat exchanger 23, either collected in the first drip tray 6 or discharged through a drain outlet on the first drip tray 6. This prevents condensate from dripping onto the ground, thus preventing the air conditioner from slipping and posing a risk of slipping and falling.

[0087] As shown in Figures 3 and 4, in some embodiments, a second drain outlet (not shown) may be provided on the bottom surface of the first water receiving tray 6. The second drain outlet is located above the outdoor heat exchanger 22 and the second water receiving tray 5. The condensate in the first water receiving tray 6 can flow through the second drain outlet onto the outdoor heat exchanger 22, cooling the outdoor heat exchanger 22, and then flow down along the outer wall of the outdoor heat exchanger 22 into the second water receiving tray 5. In this way, the condensate in the first water receiving tray 6 can be discharged into the second water receiving tray 5 for collection, and heat exchange can be performed between the condensate and the outdoor heat exchanger 22 to cool the outdoor heat exchanger 22. For example, when the air conditioner is cooling, the outdoor heat exchanger 22, acting as a condenser, needs to dissipate heat to the outside, while the indoor heat exchanger 23, acting as an evaporator, needs to absorb heat to the outside. Air condenses into condensate on the surface of the indoor heat exchanger 23. The condensate can flow along the surface of the indoor heat exchanger 23 into the first water collection pan 6, and then through the second drain outlet of the first water collection pan 6 to the outer wall of the outdoor heat exchanger 22, dissipating heat and cooling the outdoor heat exchanger 22. Finally, it flows down the outer wall of the outdoor heat exchanger 22 into the second water collection pan 5 for collection.

[0088] As shown in Figures 3 and 4, in some embodiments, the air conditioner may include a casing 1, which includes a main casing 11 and a chassis 12, forming an internal receiving space 10. The air conditioner may include a refrigerant circulation loop disposed within the receiving space and including a compressor 21, a condenser, and an evaporator connected end-to-end. One of the condenser and evaporator is an outdoor heat exchanger 22, and the other is an indoor heat exchanger 23. The air conditioner may include an outdoor fan assembly 3, 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 may include an indoor fan assembly 4, 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 may include a second drip tray 5, with the outdoor heat exchanger 22 disposed above the second drip tray 5. The air conditioner may include a first drip tray 6, with the indoor heat exchanger 23 disposed above the first drip tray 6. The first drip tray 6 is positioned above the outdoor heat exchanger 22. The air conditioner may include an air inlet duct 14, which delivers outdoor air to the outdoor heat exchanger 22 for heat exchange. The air conditioner may also include an air outlet duct 15, which delivers the heat-exchanged air to the outside under the action of the outdoor fan assembly 3. The air inlet and outlet ducts are positioned above the outdoor heat exchanger and are horizontally spaced from the indoor fan assembly. The compressor is located at the bottom of the casing, and the first drip tray is positioned above the compressor.

[0089] As shown in Figures 4 and 5, in some embodiments, the air conditioner may include a support member 7. The support member 7 may be disposed within the housing 1. The support member 7 may be disposed within the main housing 11. The support member 7 may be disposed within the receiving space 10. The support member 7 can be used to support the internal structure of the air conditioner. For example, the support member 7 can be used to support the outdoor heat exchanger 22, the outdoor fan assembly 3, the second drip tray 5, the indoor heat exchanger 23, the indoor fan assembly 4, the first drip tray 6, etc., thereby increasing the structural strength and stability of the air conditioner's internal structure.

[0090] As shown in Figures 4 and 5, in some embodiments, the lower part of the support member 7 can be located within the first subspace 110, and the bottom end of the support member 7 can be fixed to the chassis 12. The upper part of the support member 7 can be located within the second subspace 120, and the top end of the support member 7 can be supported at the bottom of the first water receiving tray 6, facilitating the installation of the indoor heat exchanger 23 and the indoor fan assembly 4 on the first water receiving tray 6. This allows the indoor heat exchanger 23 and the indoor fan assembly 4 to be supported on the top end of the support member 7 via the first water receiving tray 6, thereby improving the structural stability of the indoor heat exchanger 23 and the indoor fan assembly 4 within the third subspace 130.

[0091] As shown in Figures 4 and 5, in some embodiments, the second water receiving tray 5 can be supported and fixed on the upper part of the support member 7, facilitating the installation of the outdoor heat exchanger 22 on the second water receiving tray 5 and its support and fixation on the support member 7. The outdoor fan assembly 3 can be located on the upper part of the support member 7. This facilitates the improvement of the structural stability of the outdoor heat exchanger 22 and the outdoor fan assembly 3 within the second subspace 120.

[0092] It should be noted that in some other embodiments, the support member 7 can also be used to support any one or more of the outdoor heat exchanger 22, outdoor fan assembly 3, second water receiving tray 5, indoor heat exchanger 23, indoor fan assembly 4, and first water receiving tray 6. For example, the support member 7 can also be used to support the outdoor heat exchanger 22 and / or the indoor heat exchanger 23 alone.

[0093] In some embodiments, the outdoor fan assembly 3 may include an outdoor duct housing 30. An outdoor duct may be formed inside the outdoor duct housing 30. The air inlet of the outdoor duct housing 30 may connect to the outside, and the air outlet of the outdoor duct housing 30 may face the outdoor heat exchanger 22. Specifically, the air inlet of the outdoor duct housing 30 may connect to an air inlet pipe 14, and through the air inlet pipe 14, connect to the outdoor space. The air outlet of the outdoor duct housing 30 may be arranged facing the outdoor heat exchanger 22. Thus, the duct inside the outdoor duct housing 30 can draw air from the outdoor space through the air inlet pipe 14, introduce outdoor air into the housing 1, and blow it towards the outdoor heat exchanger 22 to heat or cool the outdoor heat exchanger 22.

[0094] As shown in Figures 5, 6, and 7, in some embodiments, the outdoor duct housing 30 may include a volute member 31. The volute member 31 may be fixed to the support member 7. The air duct within the outdoor duct housing 30 may be formed within the volute member 31.

[0095] It should be noted that in some other embodiments, the outdoor duct housing 30 may not use the volute 31, that is, it may not use the volute structure, and the outdoor duct housing 30 may use duct housings of other shapes.

[0096] As shown in Figures 6 and 7, in some embodiments, a volute portion 71 can be formed on the upper part of the support member 7. A volute member 31 can be fixed to the volute portion 71, thereby fixing the volute member 31 to the support member 7. The volute member 31 and the volute portion 71 can be joined to form a volute structure, within which an outdoor air duct can be formed. That is, the volute member 31 and the volute portion 71 can be joined to form a complete outdoor air duct housing 30. This volute structure has an air inlet end and an air outlet end. The air inlet end of the volute structure connects to the air inlet pipe 14, thereby connecting to the outdoor space. The air outlet end of the volute structure connects to the second subspace 120 and is arranged towards the outdoor heat exchanger 22.

[0097] It should be noted that in some other embodiments, the outdoor duct housing 30 can also be formed by joining two opposing volute components 31 together. The joined outdoor duct housing 30 can also be detachably fixed to the support member 7. Alternatively, the outdoor duct housing 30 can also be formed by a single complete volute component 31.

[0098] As shown in Figures 6 and 7, in some embodiments, the outdoor fan assembly 3 may include an outdoor impeller 33. The outdoor impeller 33 is rotatably disposed within the outdoor duct housing 30, that is, the outdoor impeller 33 is rotatably disposed within the outdoor duct. The outdoor impeller 33 is rotatably disposed inside the volute component 31. When the outdoor impeller 33 rotates, wind power can be generated inside the volute structure, allowing air from the outdoor space to enter the volute structure through the air inlet pipe 14, that is, into the outdoor duct.

[0099] As shown in Figures 6 and 7, in some embodiments, the outdoor fan assembly 3 may include an outdoor motor 32. The outdoor motor 32 may be mounted on the volute 31. The outdoor motor 32 may be fixed to the outside of the volute 31, with its output shaft extending into the inside of the volute 31 and drivingly connected to the outdoor impeller 33. Thus, the outdoor motor 32 can drive the outdoor impeller 33 to rotate inside the outdoor duct housing 30, thereby drawing air from the outdoor space into the outdoor duct housing 30 through the inlet pipe 14 and blowing it into the second sub-space 120 to contact and exchange heat with the outdoor heat exchanger 22. The heat-exchanged air can then flow to the outside through the outlet pipe 15. This design integrates part of the outdoor duct housing 30 of the outdoor fan assembly 3 onto the support member 7, which can greatly improve the structural strength and stability of the outdoor fan assembly 3, effectively ensuring the stable operation of the outdoor fan assembly 3. Figure 8 is a schematic diagram of the structure of the volute 31 in Figure 7.

[0100] As shown in Figures 7 and 8, in some embodiments, a water-receiving portion 311 is provided on the outer wall of the outdoor duct housing 30. The water-receiving portion 311 can be located on the outer wall of the volute member 31. The water-receiving portion 311 can be a groove-shaped structure. In the heating mode of the air conditioner, condensate forms on the outer wall of the outdoor duct housing 30, and the condensate can flow downward along the outer wall of the outdoor duct housing 30, flowing into the water-receiving portion 311. Specifically, condensate can form on the outer wall of the volute member 31, and the condensate can flow downward along the outer wall of the volute member 31 into the water-receiving portion 311.

[0101] As shown in Figures 7 and 9, in some embodiments, a guide hole 312 may be provided on the outer wall of the outdoor duct housing 30. The guide hole 312 may be provided on the outer wall of the volute member 31. The guide hole 312 may be arranged opposite to the water receiving part 311. The guide hole 312 may connect the water receiving part 311 and the interior of the outdoor duct housing 30. The guide hole 312 may connect the water receiving part 311 and the inner space of the volute member 31. Condensate on the outer wall of the outdoor duct housing 30 can flow downward into the water receiving part 311 and enter the interior of the outdoor duct housing 30 through the guide hole 312. Specifically, condensate can flow downward along the outer wall of the volute member 31 into the water receiving part 311, and then enter the interior of the volute member 31 through the guide hole 312. This allows condensate to drain easily from inside the outdoor duct housing 30, preventing condensate from dripping directly from the outer wall of the duct housing and splashing onto the ground, effectively increasing the condensate drainage performance of the outdoor fan assembly of the air conditioner.

[0102] As shown in Figures 7 and 10, in some embodiments, a drain hole 34 may be provided on the inner bottom surface of the outdoor duct housing 30. Condensate from the outdoor duct housing 30 or condensate formed inside the outdoor duct housing 30 can flow along the inner wall to the bottom area inside the outdoor duct housing 30 and be discharged downwards through the drain hole 34. This facilitates the discharge of condensate from the drain hole 34 inside the outdoor duct housing 30, preventing condensate from dripping directly from the outer wall of the duct housing and splashing onto the ground, effectively increasing the condensate drainage performance of the air conditioner's outdoor fan assembly.

[0103] It should be noted that in some other embodiments, rainwater entering the outdoor duct housing 30 through the air inlet pipe 14 can also flow along the inner wall to the bottom area inside the outdoor duct housing 30 and be discharged downward through the drain hole 34.

[0104] As shown in Figures 7 and 10, in some embodiments, multiple drainage holes 34 may be provided. Multiple drainage holes 34 may be arranged at intervals on the inner bottom surface of the outdoor air duct housing 30.

[0105] As shown in Figure 7, in some embodiments, the plurality of drainage holes 34 may include a first drainage hole 341. The first drainage hole 341 may be located at the bottom of the volute portion 71. In this way, condensate or rainwater in the outdoor duct housing 30 can flow down along the inner wall to the first drainage hole 341 and be discharged downward through the first drainage hole 341.

[0106] As shown in Figure 10, in some embodiments, the plurality of drainage holes 34 may include a second drainage hole 342. The second drainage hole 342 may be located at the bottom of the volute member 31. The second drainage hole 342 may be located at the side edge of the volute member 31 near the volute portion 71. When the volute member 31 and the volute portion 71 are joined to form the outdoor air duct housing 30, the second drainage hole 342 may be located at the joint between the volute member 31 and the volute portion 71. In this way, condensate or rainwater inside the outdoor air duct housing 30 can flow downwards along the joint between the volute member 31 and the volute portion 71 to the second drainage hole 342, and then be discharged downwards through the second drainage hole 342, improving the discharge efficiency of condensate or rainwater.

[0107] It should be noted that in some other embodiments, the plurality of drainage holes 34 may also include a third drainage hole or a fourth drainage hole. The position of the third drainage hole or the fourth drainage hole can be adjusted as needed, and is not limited here.

[0108] As shown in Figures 8 and 9, in some embodiments, a first water-blocking rib 313 may be provided along the outer periphery of the outer wall of the volute 31. The first water-blocking rib 313 may be located at the outer periphery of the outer wall of the outdoor air duct housing 30. The water receiving part 311 and the guide hole 312 may be located inside the first water-blocking rib 313. In this way, condensate on the outer wall of the volute 31 can flow downward along the outer wall of the volute 31, and the flow direction of the condensate is restricted by the first water-blocking rib 313, guiding the condensate to the water receiving part 311, and then entering the interior of the volute 31 through the guide hole 312.

[0109] As shown in Figures 8 and 9, in some embodiments, the water receiving portion 311 and the guide hole 312 can be located in the bottom region of the outer wall of the volute 31. The water receiving portion 311 can be located in the bottom region inside the first water-blocking rib 313. In this way, condensate on the outer wall of the volute 31 can flow downward along the outer wall of the volute 31 to the bottom region inside the first water-blocking rib 313, thereby smoothly collecting the condensate at the water receiving portion 311, and then entering the interior of the volute 31 through the guide hole 312.

[0110] As shown in Figures 8 and 9, in some embodiments, a flange 3131 may be provided on the outer side wall of the volute 31. The flange 3131 may be provided in the bottom region of the first water-blocking rib 313. The flange 3131 may extend upward from the bottom region of the first water-blocking rib 313. The flange 3131 may be provided at intervals on the outside of the drain hole 34. The water receiving portion 311 may be formed between the first water-blocking rib 313, the flange 3131, and the outer side wall of the volute 31. Thus, when the condensate on the outer wall of the volute 31 flows downward along the outer wall of the volute 31, the flow direction of the condensate is restricted by the first water-blocking rib 313, and the trough structure between the first water-blocking rib 313, the flange 3131 and the outer wall of the volute 31, and the condensate is collected at the water receiving part 311, which facilitates the condensate in the water receiving part 311 to enter the interior of the volute 31 through the guide hole 312.

[0111] As shown in Figures 8 and 9, in some embodiments, the outer wall of the volute 31 may be provided with a second water-blocking rib 314. The second water-blocking rib 314 may be annular and arranged around the outer periphery of the outdoor motor 32. The second water-blocking rib 314 may be located inside the first water-blocking rib 313. The second water-blocking rib 314 and the first water-blocking rib 313 may be arranged with an inner and outer gap. The first water-blocking rib 313 may be arranged around the outer periphery of the second water-blocking rib 314. The water receiving part 311 and the guide hole 312 may be provided in the bottom area of ​​the space between the first water-blocking rib 313 and the second water-blocking rib 314. Thus, a water collection channel can be formed in the space between the first water-blocking rib 313 and the second water-blocking rib 314. By cooperating with the first water-blocking rib 313, the condensate on the outer wall of the volute 31 can be confined in the water collection channel between the second water-blocking rib 314 and the first water-blocking rib 313, and then flow smoothly to the bottom area of ​​the water collection channel and into the water receiving part 311, so that the condensate can smoothly enter the interior of the volute 31 through the guide hole 312.

[0112] As shown in Figures 7 and 9, in some embodiments, an assembly opening 315 may be provided on the outer wall of the volute 31. The outdoor motor 32 may be located at the assembly opening 315. A second water-blocking rib 314 may be arranged around the outer periphery of the assembly opening 315. In this way, condensate on the outer wall of the volute 31 can be prevented from overflowing the second water-blocking rib 314, and condensate can be prevented from contacting the outdoor motor 32 through the assembly opening 315, thus ensuring the safe and stable operation of the outdoor motor 32.

[0113] As shown in Figures 8 and 9, in some embodiments, the outer wall of the volute 31 may be provided with a first water-guiding rib 3132. The first water-guiding rib 3132 may be located in the space between the first water-blocking rib 313 and the second water-blocking rib 314. That is, the first water-guiding rib 3132 may be located within the water collection channel. The first water-guiding rib 3132 may extend from the first water-blocking rib 313 toward the second water-blocking rib 314. There is a gap between the first water-guiding rib 3132 and the second water-blocking rib 314. In this way, the condensate on the upper side of the first water-guiding rib 3132 can flow along the direction from the first water-guiding rib 3132 toward the second water-blocking rib 314, and flow downward through the gap between the first water-guiding rib 3132 and the second water-blocking rib 314, so that the condensate can quickly flow toward the bottom area of ​​the space between the first water-blocking rib 313 and the second water-blocking rib 314, and smoothly collect in the water receiving part 311.

[0114] As shown in Figures 8 and 9, in some embodiments, multiple first water-guiding ribs 3132 may be provided in the spaced area between the first water-blocking rib 313 and the second water-blocking rib 314. The multiple first water-guiding ribs 3132 may be arranged circumferentially. The cooperation of the multiple first water-guiding ribs 3132 can improve the flow efficiency of condensate, allowing the condensate to collect smoothly in the water receiving part 311.

[0115] As shown in Figures 8 and 9, the outer wall of the volute 31 may be provided with a second water-guiding rib 3141. The second water-guiding rib 3141 may be located in the interval area between the first water-blocking rib 313 and the second water-blocking rib 314. That is, the second water-guiding rib 3141 may be located in the water collection channel. The second water-guiding rib 3141 may extend from the second water-blocking rib 314 towards the first water-blocking rib 313. There may be a gap between the second water-guiding rib 3141 and the first water-blocking rib 313. In this way, the condensate on the upper side of the second water-guiding rib 3141 may flow along the direction of the second water-guiding rib 3141 towards the first water-blocking rib 313, and flow downward through the gap between the second water-guiding rib 3141 and the first water-blocking rib 313, so that the condensate can quickly flow towards the bottom area of ​​the interval area between the first water-blocking rib 313 and the second water-blocking rib 314, and smoothly collect in the water receiving part 311.

[0116] As shown in Figures 8 and 9, in some embodiments, multiple second water-guiding ribs 3141 may be provided in the spaced area between the first water-blocking rib 313 and the second water-blocking rib 314. The multiple second water-guiding ribs 3141 may be arranged circumferentially. The cooperation of the multiple second water-guiding ribs 3141 can improve the flow efficiency of condensate, allowing the condensate to collect smoothly in the water receiving part 311.

[0117] As shown in Figures 8 and 9, in some embodiments, the first water-blocking rib 313 protrudes from the outer wall of the volute 31 by a height greater than 3 mm. The second water-blocking rib 314 protrudes from the outer wall of the volute 31 by a height greater than 3 mm. This prevents condensate from overflowing in the area between the first water-blocking rib 313 and the second water-blocking rib 314.

[0118] As shown in Figures 3 and 4, in some embodiments, a fixing rod 114 may be provided inside the housing 1. The fixing rod 114 may be located inside the main housing 11. The fixing rod 114 may extend vertically. One side of the outdoor fan assembly 3 may be fixed to the fixing rod 114. One side of the second water receiving tray 5 may be fixed to the fixing rod 114. One side of the indoor fan assembly 4 may be fixed to the fixing rod 114. One side of the first water receiving tray 6 may be fixed to the fixing rod 114. In this way, the fixing rod 114 can improve the structural strength and structural stability of multiple components inside the housing 1.

[0119] As shown in Figures 3 and 4, in some embodiments, there may be two fixing rods 114 inside the housing 1. The two fixing rods 114 may be located on opposite sides inside the main housing 11. The outdoor fan assembly 3, the second water receiving tray 5, the indoor fan assembly 4, and the first water receiving tray 6 may be fixed to either of the two fixing rods 114.

[0120] As shown in Figures 4, 8, and 9, in some embodiments, a fixing part 316 may be provided on the outer wall of the volute housing 31. The fixing part 316 may be arranged vertically at the center of the outer wall of the volute housing 31. The fixing part 316 may be fixedly connected to the fixing rod 114. Two water receiving parts 311 may be provided on the outer wall of the volute housing 31. The two water receiving parts 311 may be respectively provided on opposite sides of the fixing part 316. Both water receiving parts 311 are provided on the inner side of the first water-blocking rib 313. Two flow guiding holes 312 may be provided on the outer wall of the volute housing 31. The two flow guiding holes 312 may be arranged corresponding to the two water receiving parts 311 respectively. In addition, two flanged parts 3131 may also be provided. The two flanged parts 3131 may be arranged corresponding to the two flow guiding holes 312 respectively, thereby forming a water receiving part 311 on each of the two flanged parts 3131.

[0121] It should be noted that in some other embodiments, the number of water receiving parts 311 and guide holes 312 can be adjusted as needed.

[0122] As shown in Figures 6, 11, and 12, in some embodiments, the air conditioner may include an electrical control box 8. The electrical control box 8 may be located inside the housing 1. The electrical control box 8 may be located within the accommodating space 10. The electrical control box 8 may be electrically connected to the compressor 21, the outdoor fan assembly 3, and the indoor fan assembly 4, respectively. Thus, the electrical control box 8 can control the on / off state of the circuits of the compressor 21, the outdoor fan assembly 3, and the indoor fan assembly 4, thereby controlling the normal operation of the air conditioner.

[0123] As shown in Figures 4 and 12, in some embodiments, the electrical control box 8 may be located within the first subspace 110. The electrical control box 8 may be located above the chassis 12. The electrical control box 8 may be located on one side of the support member 7. The electrical control box 8 may be located below the volute member 31.

[0124] As shown in Figures 6, 11, and 12, in some embodiments, the air conditioner may include a reactor assembly 9. The reactor assembly 9 may include a reactor.

The reactor assembly 9 may be disposed on one side of the electrical control box 8. The reactor assembly 9 may be disposed above the chassis 12. The reactor may be electrically connected to components such as the main control board within the electrical control box 8. The reactor may function to filter, stabilize current and voltage, improve power factor, or suppress inrush current, etc.

[0125] As shown in Figures 13 and 14, in some embodiments, the lower part of the support member 7 may include a support plate 72. The support plate 72 may be arranged laterally within the first subspace 110. The upper end of the support plate 72 may be integrally connected to the lower end of the volute portion 71. The lower end of the support plate 72 may be supported and fixed on the chassis 12. The lateral width of the support plate 72 may be substantially the same as the lateral width of the volute portion 71, so that the volute portion 71 can be supported on the chassis 12 by the support plate 72, further improving the structural strength and structural stability of the outdoor fan assembly 3.

[0126] It should be noted that in some other embodiments, the upper and lower parts of the support member 7 can also be separate structures, that is, the volute 71 and the support plate 72 can also be separate structures. The volute 71 can be detachably fixed to the upper end of the support plate 72.

[0127] As shown in Figures 5, 6, and 7, in some embodiments, the lower part of the support member 7 may include a first support wall 73 and a second support wall 74. The first support wall 73 may extend from one lateral end of the support plate 72 toward one side of the support plate 72. The second support wall 74 may extend from the other lateral end of the support plate 72 toward the same side of the support plate 72. The lower ends of the first support wall 73 and the second support wall 74 may be supported and fixed to the chassis 12. The second drip tray 5 may be simultaneously supported and fixed to the support plate 72, the first support wall 73, and the second support wall 74, thereby improving the support reliability of the second drip tray 5 and improving the structural stability of the second drip tray 5. In addition, the support plate 72, the first support wall 73, and the second support wall 74 may form a frame-like three-sided structure, which can effectively improve the structural strength of the lower part of the support member 7 and further improve the structural strength and structural stability inside the air conditioner.

[0128] As shown in Figures 15 and 16, in some embodiments, a support portion 121 may be provided on the top surface of the chassis 12. The bottom end of the support member 7 may be supported on the support portion 121. The support plate 72, the first support wall 73, and the second support wall 74 at the lower part of the support member 7 may be supported on the support portion 121 respectively, thereby improving the support stability of the lower part of the support member 7.

[0129] As shown in Figures 14 and 16, in some embodiments, the support portion 121 may include a first support rib 1211 and a second support rib 1212 arranged at intervals. The first support rib 1211 may protrude from the top surface of the chassis 12. The second support rib 1212 may protrude from the top surface of the chassis 12 and be arranged at intervals relative to the first support rib 1211. A support groove 1213 may be formed between the first support rib 1211 and the second support rib 1212. The bottom end of the support member 7 may be inserted into the support groove 1213, and the opposite side walls of the bottom end of the support member 7 may be supported on the first support rib 1211 and the second support rib 1212 respectively, thereby improving the structural strength and structural stability of the connection between the bottom end of the support member 7 and the chassis 12, and enhancing the reliability of the support portion 121 in supporting the support member 7.

[0130] Specifically, the lower end of the support plate 72 can be inserted and fixed in the support groove 1213, and the opposite side walls of the lower end of the support plate 72 are respectively supported on the first support rib 1211 and the second support rib 1212; the lower end of the first support wall 73 can be inserted and fixed in the support groove 1213, and the opposite side walls of the lower end of the first support wall 73 are respectively supported on the first support rib 1211 and the second support rib 1212; the lower end of the second support wall 74 can be inserted and fixed in the support groove 1213, and the opposite side walls of the lower end of the second support wall 74 are respectively supported on the first support rib 1211 and the second support rib 1212.

[0131] As shown in Figures 7, 14, and 16, in some embodiments, a water collection trough 100 may be provided on the top surface of the chassis 12. The water collection trough 100 may be located in the bottom area of ​​the accommodating space 10. The water collection trough 100 can be used to collect and receive rainwater or condensate from inside the housing 1. A water guiding structure may be provided below the drain hole 34. Water discharged downward from the drain hole 34 on the outdoor air duct housing 30 can fall into the water guiding structure and flow into the water collection trough 100 through the water guiding structure, so that rainwater or condensate can be collected in the water collection trough 100 and prevented from overflowing directly onto the bottom surface of the housing 1.

[0132] As shown in Figures 7, 14, and 16, in some embodiments, during storms or heavy rain, rainwater can easily enter the air conditioner through the air inlet duct 14 and then into the outdoor duct housing 30. Rainwater entering the outdoor duct housing 30 can also be discharged downwards through the drain hole 34 and flow into the water collection tank 100 via the water guiding structure, preventing rainwater from flowing directly to the ground and effectively solving the problem of rainwater entering the air conditioner through the air inlet duct 14.

[0133] It should be noted that in some other embodiments, the water collection tank 100 may also be located in other areas of the accommodating space 10. For example, the water collection tank 100 may also be located in the second water receiving tray 5, or the water collection tank 100 may also be located in other areas above the chassis 12 within the first subspace 110.

[0134] As shown in Figures 7, 14, and 16, the water guiding structure can be provided on the side wall of the support member 7. Water discharged downward from the drain hole 34 on the outdoor air duct housing 30 can flow downward along the side wall of the support member 7 into the water collection tank 100, facilitating the collection of rainwater or condensate within the water collection tank 100 and preventing direct overflow onto the bottom surface of the outer casing 1. In some embodiments, multiple water collection tanks 100 can be provided, including a first water collection tank 124 and a second water collection tank 125. The first water collection tank 124 and the second water collection tank 125 are provided on the chassis 12. The first water collection tank 124 can be provided on one side of the support portion 121. The second water collection tank 125 can be provided on the other side of the support portion 121. The first water collection tank 124 and the second water collection tank 125 can be respectively provided on opposite sides of the support portion 121. Both the first water collection tank 124 and the second water collection tank 125 can be used to collect and collect rainwater or condensate from inside the casing 1. The first water collection tank 124 and the second water collection tank 125 work together to effectively increase the water storage space of the chassis 12. Under the premise that the support 7 needs to be supported on the chassis 12, the structural arrangement of the first water collection tank 124 and the second water collection tank 125 can effectively improve the space utilization efficiency of the chassis 12, thereby reasonably expanding the water storage space of the chassis 12.

[0135] It should be noted that in some other embodiments, the multiple water collection tanks 100 may include a third water collection tank or a fourth water collection tank, etc. The number and position of the water collection tanks 100 other than the first water collection tank 124 and the second water collection tank 125 can be adjusted as needed, and are not limited here.

[0136] As shown in Figures 14 and 16, in some embodiments, the chassis 12 may be provided with a connecting channel 122 penetrating the support portion 121. One end of the connecting channel 122 may be connected to the first water collection tank 124. The other end of the connecting channel 122 may be connected to the second water collection tank 125. The connecting channel 122 connects the first water collection tank 124 and the second water collection tank 125, allowing rainwater or condensate in the first water collection tank 124 to enter the second water collection tank 125 through the connecting channel 122, and rainwater or condensate in the second water collection tank 125 to enter the first water collection tank 124 through the connecting channel 122. This fully utilizes the water storage space of the first water collection tank 124 and the second water collection tank 125, improving the storage effect of rainwater or condensate, thereby effectively enhancing and efficiently utilizing the water storage space of the chassis 12.

[0137] As shown in Figures 14 and 16, in some embodiments, the first water collection tank 124 can be located on the side of the first support rib 1211 away from the second support rib 1212. The second water collection tank 125 can be located on the side of the second support rib 1212 away from the first support rib 1211. The connecting channel 122 can sequentially pass through the first support rib 1211, the support groove 1213, and the second support rib 1212. Furthermore, the connecting channel 122 can be isolated from the support groove 1213, i.e., the connecting channel 122 can be isolated from the support groove 1213. Thus, while the connecting channel 122 connects the first water collection tank 124 and the second water collection tank 125, water in the first water collection tank 124 and the second water collection tank 125 can be prevented from entering the support groove 1213, thus preventing water residue in the support groove 1213.

[0138] As shown in Figure 16, in some embodiments, a step 126 may be provided inside the second water collection tank 125. A drain outlet 1261 may be provided on the top surface of the step 126. This drain outlet 1261 can connect to the space below the bottom of the chassis 12. Thus, when the water level in the second water collection tank 125 is higher than the top of the drain outlet 1261, excess condensate or rainwater in the second water collection tank 125 can be discharged to the outside of the casing 1 through the drain outlet 1261; excess condensate or rainwater in the first water collection tank 124 can first enter the second water collection tank 125, and then be discharged to the outside of the casing 1 through the drain outlet 1261. When there is a large amount of rainwater or condensate, and the first and second water collection tanks 124 cannot hold more water, excess water on the chassis 12 can be discharged through the drain outlet 1261, preventing excessive accumulation of rainwater or condensate inside the casing 1.

[0139] In some other embodiments, the step portion 126 and the outlet 1261 may also be provided in the first water collection tank 124. Alternatively, multiple steps 126 and outlets 1261 may be provided, with multiple steps 126 and corresponding outlets 1261 respectively provided in the first water collection tank 124 and the second water collection tank 125.

[0140] As shown in Figures 7, 13, and 15, in some embodiments, condensate or rainwater is discharged from the first drain hole 341 inside the outdoor duct housing 30. This water can flow downwards through the outer wall of the support member 7 onto the chassis 12 and be collected in the water collection tank 100 of the chassis 12. This effectively prevents rainwater or condensate from accumulating inside the outdoor duct housing 30, ensuring the stable operation of the outdoor fan assembly 3.

[0141] As shown in Figures 7, 13, and 15, in some embodiments, the sidewall of the support member 7 may be provided with vertically extending drainage channels 75. The water guiding structure may include drainage channels 75. The lower end of the drainage channel 75 is arranged above the water collection tank 100. The drainage channel 75 is arranged below the drain hole 34. For example, the lower end of the drainage channel 75 is arranged above the first water collection tank 124 or above the second water collection tank 125. In this way, after outdoor rainwater enters the outdoor air duct housing 30 through the air inlet pipe 14, it can be discharged downward through the drain hole 34. The water discharged downward through the drain hole 34 can flow into the drainage channel 75 and flow into the water collection tank 100 along the drainage channel 75.

[0142] As shown in Figures 13 and 15, in some embodiments, the sidewall of the support member 7 may be provided with a first drainage rib 721 and a second drainage rib 722 extending vertically. The water guiding structure may include the first drainage rib 721 and the second drainage rib 722. The first drainage rib 721 and the second drainage rib 722 may be arranged opposite each other with a left-right interval. The drainage channel 75 may be formed in the region between the first drainage rib 721 and the second drainage rib 722. In this way, water discharged downward from the drain hole 34 can flow into the region between the first drainage rib 721 and the second drainage rib 722, and flow downward along the region between the first drainage rib 721 and the second drainage rib 722 into the water collection tank 100 of the chassis 12.

[0143] As shown in Figures 13 and 15, in some embodiments, the sidewall of the support member 7 may be provided with a guide rib 723. The water guiding structure may include the guide rib 723. The guide rib 723 may be located above the first guide rib 721. The guide rib 723 may be located below the volute portion 71. The upper end of the guide rib 723 may extend below the first drain hole 341. The guide rib 723 may be located on the side of the upper end of the first guide rib 721 away from the second guide rib 722. The lower end of the guide rib 723 may extend to the upper end of the first guide rib 721. The lower end of the guide rib 723 may extend to the drainage channel 75. In this way, the condensate or rainwater discharged from the first drain hole 341 in the outdoor air duct housing 30 can flow through the guide rib 723 to the first guide rib 721, and then flow into the drainage channel 75, and flow downwards into the water collection tank 100 along the drainage channel 75.

[0144] It should be noted that in some other embodiments, the guide rib 723 may also be located above the second drain rib 722. The guide rib 723 may be located on the side of the upper end of the second drain rib 722 away from the first drain rib 721. The lower end of the guide rib 723 may extend to the upper end of the second drain rib 722, so that the lower end of the guide rib 723 may extend to the drain channel 75. In this way, the condensate or rainwater discharged from the first drain hole 341 can flow through the guide rib 723 to the second drain rib 722, and then flow into the drain channel 75, and flow downward along the drain channel 75 into the water collection tank 100.

[0145] As shown in Figures 7, 13, and 15, in some embodiments, condensate or rainwater is discharged from the second drain hole 342 inside the outdoor duct housing 30. This water can flow downwards through the outer wall of the support member 7 onto the chassis 12 and be collected in the water collection tank 100 of the chassis 12. This effectively prevents rainwater or condensate from accumulating inside the outdoor duct housing 30, ensuring the stable operation of the outdoor fan assembly 3.

[0146] As shown in Figures 12, 13, and 15, in some embodiments, a receiving groove 76 may be provided on the side wall of the support member 7. The receiving groove 76 may be arranged in the lower region of the volute member 31. The receiving groove 76 may be arranged below the drain hole 34. For example, the receiving groove 76 may be arranged below the first drain hole 341 or the second drain hole 342. The water guiding structure may include the receiving groove 76. The drainage channel 75 may communicate with the receiving groove 76. In this way, condensate or rainwater discharged downward from the drain hole 34 can flow downward into the receiving groove 76, flow into the drainage channel 75, and then flow downward along the drainage channel 75 into the water collection tank 100.

[0147] As shown in Figures 12 and 15, in some embodiments, the receiving groove 76 and the drainage channel 75 can be arranged on opposite side walls of the support member 7. A water inlet hole 724 can be provided on the side wall of the support member 7. The water inlet hole 724 can connect the receiving groove 76 and the drainage channel 75. The water guiding structure can include the water inlet hole 724. Thus, condensate or rainwater discharged downwards from the drain hole 34 can flow downwards into the receiving groove 76, flow into the drainage channel 75 through the water inlet hole 724, and then flow downwards along the drainage channel 75 into the water collection tank 100. Specifically, the receiving groove 76 can be arranged below the second drain hole 342. Condensate or rainwater discharged from the second drain hole 342 in the outdoor air duct housing 30 can flow downwards into the receiving groove 76, flow into the drainage channel 75 through the water inlet hole 724, and then flow downwards along the drainage channel 75 into the water collection tank 100.

[0148] As shown in Figures 12 and 15, in some embodiments, the water inlet 724 can be arranged in the upper region of the drainage channel 75. Thus, water in the receiving tank 76 can flow through the water inlet 724 to the upper region of the drainage channel 75, then flow downwards into the drainage channel 75, and finally flow downwards into the water collection tank 100.

[0149] As shown in Figures 11, 12, and 13, in some embodiments, the top surface of the electrical control box 8 may be recessed with a guide groove 81. The guide groove 81 is located above one side of the receiving groove 76. The guide groove 81 may be arranged at an angle. The guide groove 81 may extend at an angle toward one side of the receiving groove 76. The guide groove 81 may be arranged in the lower region of the volute 31. The guide groove 81 may be arranged below the drain hole 34. The water guiding structure may include the guide groove 81. In this way, the condensate or rainwater discharged downward from the drain hole 34 can first fall into the guide groove 81, and flow along the guide groove 81 into the receiving groove 76, flow into the drainage channel 75 through the water inlet hole 724, and then flow downward along the drainage channel 75 into the water collection tank 100. Specifically, the guide channel 81 can be arranged below the second drain hole 342. The condensate or rainwater discharged from the second drain hole 342 in the outdoor air duct housing 30 can first fall into the guide channel 81 and flow along the guide channel 81 to the receiving groove 76. It then flows into the drainage channel 75 through the water inlet hole 724 and then flows down into the water collection tank 100 along the drainage channel 75. This can prevent rainwater or condensate from entering the electrical control box 8 and avoid safety problems such as short circuits in the electrical components in the electrical control box 8, effectively improving the safety and reliability of the air conditioner operation.

[0150] It should be noted that in some other embodiments, some of the condensate on the outer wall of the volute 31 can also drip onto the guide groove 81 through its bottom area, flow along the guide groove 81 into the receiving groove 76, flow into the drainage channel 75 through the water inlet hole 724, and then flow down into the water collection tank 100 along the drainage channel 75.

[0151] As shown in Figures 11 and 12, in some embodiments, a flow outlet 82 may be provided on the top side of the electrical control box 8 facing the receiving groove 76. The water guiding structure may include the flow outlet 82. The flow outlet 82 may be located at the bottom of the flow guide groove 81. The flow outlet 82 may be arranged above the receiving groove 76. In this way, condensate or rainwater falling into the flow guide groove 81 can flow along the flow guide groove 81 to the flow outlet 82, and then flow into the receiving groove 76 through the flow outlet 82, preventing condensate or rainwater from flowing down the outer wall of the electrical control box 8, thereby preventing condensate or rainwater from entering the electrical control box 8, avoiding safety problems such as short circuits of electrical components in the electrical control box 8, and effectively improving the safety and reliability of the air conditioner operation.

[0152] As shown in Figures 12 and 13, in some embodiments, a guide wall 725 may be provided on the side wall of the support member 7. The water guiding structure may include the guide wall 725. The guide wall 725 may be provided above the receiving groove 76. The guide wall 725 may be provided below the volute portion 71 and the volute member 31. The guide wall 725 may be arranged inclined towards the guide groove 81. The lower end of the guide wall 725 may be arranged above the guide groove 81. In this way, some of the condensate on the outer wall of the volute portion 71 and the volute member 31 may also flow downward along the guide wall 725, flow into the guide groove 81, then flow along the guide groove 81 into the receiving groove 76, flow into the guide channel 75 through the water inlet hole 724, and then flow downward along the guide channel 75 into the water collection tank 100.

[0153] As shown in Figures 2, 4, and 17, in some embodiments, the air conditioner may include a mounting base 16. The mounting base 16 may be disposed on the outer wall of the housing 1. The mounting base 16 may be used to provide connection positions and installation space for the air inlet duct 14 and the air outlet duct 15.

[0154] As shown in Figures 4 and 17, in some embodiments, the mounting base 16 may be located at the bottom of the receiving area 140. The air inlet duct 14 and the air outlet duct 15 may be arranged above the top of the mounting base 16.

[0155] As shown in Figures 4, 17, and 18, in some embodiments, the mounting base 16 may be provided with a first mounting port 161. The first mounting port 161 may be located on the top surface of the mounting base 16. The first mounting port 161 may extend vertically through the mounting base 16. The first mounting port 161 may communicate with the air inlet end of the outdoor fan assembly 3, that is, the first mounting port 161 may communicate with the air inlet end of the outdoor duct housing 30. The bottom end of the air inlet pipe 14 may be connected to the first mounting port 161, thereby communicating with the air inlet end of the outdoor fan assembly 3 through the first mounting port 161. The top end of the air inlet pipe 14 may be used to connect to the outdoor space.

[0156] As shown in Figures 4 and 17, in some embodiments, the first mounting port 161 can be arranged above the outdoor duct housing 30, thereby placing the bottom end of the air inlet pipe 14 above the outdoor duct housing 30, so that the bottom end of the air inlet pipe 14 is connected to the air inlet end of the outdoor duct housing 30. In this way, after outdoor rainwater enters the air inlet pipe 14, it can flow sequentially through the bottom end of the air inlet pipe 14, the first mounting port 161, and the air inlet end of the outdoor duct housing 30 into the interior of the outdoor duct housing 30, and finally be discharged downwards through the drain hole 34.

[0157] As shown in Figures 4, 17, and 18, in some embodiments, the mounting base 16 may be provided with a second mounting port 162. The second mounting port 162 may be located on the top surface of the mounting base 16. The second mounting port 162 may extend vertically through the mounting base 16. The second mounting port 162 may communicate with the receiving space 10. The bottom end of the air outlet duct 15 may be connected to the second mounting port 162, thereby communicating with the receiving space 10 through the second mounting port 162. The top end of the air outlet duct 15 may be used to connect to an outdoor space.

[0158] As shown in Figures 4 and 17, in some embodiments, the second mounting port 162 can communicate with the second subspace 120. The second mounting port 162 can be arranged above the second water receiving tray 5, thereby arranging the bottom end of the air outlet duct 15 above the second water receiving tray 5. In this way, after outdoor rainwater enters the air outlet duct 15, it can fall into the second water receiving tray 5 sequentially through the bottom end of the air outlet duct 15 and the second mounting port 162, and be collected in the second water receiving tray 5, or it can be discharged through the first drain outlet 51 on the side wall of the second water receiving tray 5.

[0159] As shown in Figures 4 and 17, in some embodiments, the first mounting port 161 and the second mounting port 162 can be arranged adjacently on the mounting base 16 so that the air inlet pipe 14 and the air outlet pipe 15 are arranged adjacently on the mounting base 16, which helps to reduce the size of the device.

[0160] As shown in Figures 4, 19, and 20, in some embodiments, the air conditioner may include a mounting base 17. The mounting base 17 may be located outside the housing 1. The mounting base 17 may be connected to the air inlet pipe 14 and the air outlet pipe 15 respectively. The mounting base 17 is used to install on a wall or window, thereby fixing one end of the air inlet pipe 14 and the air outlet pipe 15 to the wall or window respectively, so that one end of the air inlet pipe 14 and the air outlet pipe 15 are respectively connected to the outside.

[0161] As shown in Figures 19 and 20, in some embodiments, the top end of the air inlet duct 14 can be fixedly connected to the mounting base 17. That is, the top end of the air inlet duct 14 can be fixed to a wall or window through the mounting base 17, so that the top end of the air inlet duct 14 is connected to the outside.

[0162] As shown in Figures 19 and 20, in some embodiments, the top end of the air outlet duct 15 can be fixedly connected to the mounting base 17. That is, the top end of the air outlet duct 15 can be fixed to a wall or window through the mounting base 17, so that the top end of the air outlet duct 15 connects to the outside.

[0163] As shown in Figures 20 and 21, in some embodiments, the bottom end of the air inlet pipe 14 may be provided with a first connector 141. The first connector 141 is fixed at the first mounting port 161. The first connector 141 can be sleeved on the outer periphery of the bottom end of the air inlet pipe 14. In this way, when outdoor rainwater enters the air inlet pipe 14, it can all enter the first connector 141 through the bottom end of the air inlet pipe 14, and then enter the first mounting port 161 through the first mounting port 161, and then enter the outdoor air duct housing 30 through the first mounting port 161, and be discharged through the drain hole 34, preventing rainwater from overflowing or leaking from the connection between the bottom end of the air inlet pipe 14 and the first connector 141.

[0164] As shown in Figures 20 and 21, in some embodiments, a second connector 151 may be provided at the bottom end of the air outlet duct 15. The second connector 151 is fixed at the second mounting port 162. The second connector 151 can be sleeved on the outer periphery of the bottom end of the air outlet duct 15. In this way, when outdoor rainwater enters the air outlet duct 15, it can all enter the second connector 151 through the bottom end of the air outlet duct 15, and then enter the second mounting port 162 through the second connector 151, falling into the second water receiving tray 5, preventing rainwater from overflowing or leaking from the connection between the bottom end of the air outlet duct 15 and the second connector 151.

[0165] As shown in Figures 21 and 24, in some embodiments, the first connector 141 is provided with a first extension wall 1412 facing the first mounting port 161. The first extension wall 1412 may be annular. The first extension wall 1412 may extend downward. The first extension wall 1412 may extend into the first mounting port 161 and be arranged circumferentially around the inner peripheral wall of the first mounting port 161. In this way, by the first extension wall 1412 being evenly distributed circumferentially on the inner peripheral wall of the first mounting port 161, the connection reliability between the first connector 141 and the first mounting port 161 of the mounting base 16 can be improved. At the same time, rainwater entering the air inlet duct 14 can flow entirely into the first connector 141 from the bottom, and then entirely into the first mounting port 161 from inside the first extension wall 1412, and then into the outdoor air duct housing 30, which can prevent rainwater from overflowing or leaking from the connection between the first connector 141 and the first mounting port 161.

[0166] As shown in Figures 21 and 24, in some embodiments, the second connector 151 is provided with a second extension wall 1512 facing the second mounting port 162. The second extension wall 1512 may be annular. The second extension wall 1512 may extend downward. The second extension wall 1512 extends into the second mounting port 162 and is arranged circumferentially around the inner peripheral wall of the second mounting port 162. In this way, the uniform circumferential distribution of the second extension wall 1512 on the inner peripheral wall of the second mounting port 162 can improve the connection reliability between the second connector 151 and the second mounting port 162 of the mounting base 16. At the same time, rainwater entering the air outlet duct 15 can flow entirely into the second connector 151 from the bottom, and then entirely into the second mounting port 162 from inside the second extension wall 1512, and then fall into the second water receiving tray 5, which can prevent rainwater from overflowing or leaking from the connection between the second connector 151 and the second mounting port 162.

[0167] As shown in Figures 20, 21, and 24, in some embodiments, a third extension wall 1612 may be provided at the lower end of the inner peripheral wall of the first mounting port 161. The third extension wall 1612 may extend downward. The third extension wall 1612 may extend downward into the air inlet end of the outdoor duct housing 30 and be arranged circumferentially around the inner peripheral wall of the air inlet end of the outdoor duct housing 30. In this way, rainwater entering the air inlet pipe 14 can flow entirely into the first connector 141 from the bottom, and then entirely into the first mounting port 161 from the inside of the first extension wall 1412, and then entirely into the outdoor duct housing 30 from the inside of the third extension wall 1612, which can prevent rainwater from overflowing or leaking from the connection between the first mounting port 161 and the air inlet end of the outdoor duct housing 30.

[0168] As shown in Figures 6 and 24, in some embodiments, a stepped groove 301 may be provided on the inner peripheral wall of the air inlet end of the outdoor duct housing 30. The stepped groove 301 may be circumferential. The stepped groove 301 may be arranged circumferentially on the inner peripheral wall of the air inlet end of the outdoor duct housing 30. The lower end of the third extension wall 1612 may extend into the stepped groove 301. The lower end of the third extension wall 1612 may abut against the bottom surface of the stepped groove 301. In this way, water flowing into the first mounting port 161 can flow downward through the interior of the third extension wall 1612 into the inner side of the stepped groove 301, and then fall entirely into the interior of the outdoor duct housing 30, preventing rainwater from overflowing or leaking from the connection between the first mounting port 161 and the air inlet end of the outdoor duct housing 30.

[0169] As shown in Figures 20, 21, and 24, in some embodiments, a fourth extension wall 1622 may be provided at the lower end of the inner peripheral wall of the second mounting port 162. The fourth extension wall 1622 may extend downward. The lower port of the fourth extension wall 1622 may be located within the outline of the second water receiving tray 5. In this way, rainwater entering the air outlet duct 15 can flow entirely into the second connector 151 from the bottom, and then entirely into the second mounting port 162 from the inside of the second extension wall 1512, and finally fall entirely into the second water receiving tray 5 from the inside of the fourth extension wall 1622, thus preventing rainwater from dripping from the second mounting port 162 to the outside of the second water receiving tray 5.

[0170] As shown in Figures 20 and 21, in some embodiments, the first connector 141 is rotatably connected to the first mounting port 161. Thus, the bottom end of the air inlet pipe 14 has the first connector 141, which is a rotatable connection structure, allowing the bottom end of the air inlet pipe 14 to be rotatably connected to the first mounting port 161. That is, the bottom end of the air inlet pipe 14 can rotate relative to the first mounting port 161, achieving the rotatable connection function of the bottom end of the air inlet pipe 14 relative to the first mounting port 161.

[0171] As shown in Figures 20 and 21, in some embodiments, the second connector 151 is rotatably connected to the second mounting port 162. Thus, the bottom end of the air outlet duct 15 has the second connector 151, which is a rotatable connection structure, allowing the bottom end of the air outlet duct 15 to be rotatably connected to the second mounting port 162. That is, the bottom end of the air outlet duct 15 can rotate relative to the second mounting port 162, achieving the rotatable connection function of the bottom end of the air outlet duct 15 relative to the second mounting port 162. Thus, when the mounting base 17 is installed on the cavity wall or window, the air inlet pipe 14 and the air outlet pipe 15 can maintain a reliable connection with the mounting base 17. As the mounting base 17 adjusts its installation position and angle, it can respectively drive the air inlet pipe 14 and the air outlet pipe 15 to rotate. The bottom end of the air inlet pipe 14 can rotate at the first mounting port 161, and the bottom end of the air outlet pipe 15 can rotate at the second mounting port 162, facilitating the installation of the mounting base 17 and simplifying its installation operation. Regardless of whether the mounting base 17 is installed horizontally or vertically, there is no need to disassemble the air inlet pipe 14 and the air outlet pipe 15. There is no need to install the air inlet pipe 14 and the air outlet pipe 15 separately after the mounting base 17 is installed. Installation can be completed in one go, and the installation angle is adjustable without secondary adjustments, greatly improving installation efficiency and enhancing the user's installation experience.

[0172] As shown in Figures 19, 23, and 24, in some embodiments, a first limiting rib 1611 may be provided on the inner peripheral wall of the first mounting port 161. The first limiting rib 1611 may be annular. The first limiting rib 1611 may be arranged circumferentially around the inner peripheral wall of the first mounting port 161. The first connector 141 may be provided with a first buckle 1411 facing the first mounting port 161. The first buckle 1411 may extend into the first mounting port 161 and be rotatably engaged with the side of the first limiting rib 1611 away from the air inlet pipe 14. With the first limiting ribs 1611 evenly distributed circumferentially on the inner peripheral wall of the first mounting port 161, when the air inlet pipe 14 drives the first connector 141 to rotate within the first mounting port 161, the first buckle 1411 can rotate circumferentially along the first limiting rib 1611 within the first mounting port 161. At this time, the first latch 1411 can remain engaged with the side of the first limiting rib 1611 away from the air inlet pipe 14, thereby keeping the first connector 141 rotatably connected to the first mounting port 161 and preventing the first connector 141 from detaching from the first mounting port 161. In this way, a rotatable connection between the first connector 141 and the first mounting port 161 can be achieved, while effectively preventing the first connector 141 from accidentally detaching from the first mounting port 161, thereby ensuring the connection stability and reliability of the air inlet pipe 14.

[0173] As shown in Figures 19, 23, and 24, in some embodiments, the first latch 1411 may be disposed on the inner wall of the first extension wall 1412 and extend downward from the inner wall of the first extension wall 1412. The first latch 1411 may engage with the bottom side of the first limiting rib 1611, and the first extension wall 1412 may abut against the top side of the first limiting rib 1611. In this way, by cooperating with the first extension wall 1412 and the first latch 1411, respectively engaging with the upper and lower sides of the first limiting rib 1611, the connection reliability between the first connector 141 and the first mounting port 161 of the mounting base 16 can be improved. When the first connector 141 rotates relative to the first mounting port 161, the first extension wall 1412 can rotatably abut against the top side of the first limiting rib 1611, and the first buckle 1411 can rotatably engage with the bottom side of the first limiting rib 1611, thereby maintaining the rotatable connection between the first connector 141 and the first mounting port 161, and ensuring the connection stability and reliability of the air inlet pipe 14.

[0174] As shown in Figures 6, 12, and 13, in some embodiments, a second limiting rib 1621 may be provided on the inner peripheral wall of the second mounting port 162. The second limiting rib 1621 may have a ring-shaped structure. The second limiting rib 1621 may be arranged circumferentially around the inner peripheral wall of the second mounting port 162. The second connector 151 may be provided with a second buckle 1511 facing the second mounting port 162. The second buckle 1511 may extend into the second mounting port 162 and be rotatably engaged with the side of the second limiting rib 1621 away from the air outlet pipe 15. With the second limiting ribs 1621 evenly distributed circumferentially on the inner peripheral wall of the second mounting port 162, when the air outlet pipe 15 drives the second connector 151 to rotate within the second mounting port 162, the second buckle 1511 can rotate circumferentially along the second limiting rib 1621 within the second mounting port 162. At this time, the second latch 1511 can remain engaged with the side of the second limiting rib 1621 away from the air outlet duct 15, thereby keeping the second connector 151 rotatably connected to the second mounting port 162 and preventing the second connector 151 from detaching from the second mounting port 162. In this way, a rotatable connection between the second connector 151 and the second mounting port 162 can be achieved, while effectively preventing the second connector 151 from accidentally detaching from the second mounting port 162, thus ensuring the connection stability and reliability of the air outlet duct 15.

[0175] As shown in Figures 6, 12, and 13, in some embodiments, the second latch 1511 may be disposed on the inner wall of the second extension wall 1512 and extend downward from the inner wall of the second extension wall 1512. The second latch 1511 may engage with the bottom side of the second limiting rib 1621, and the second extension wall 1512 may abut against the top side of the second limiting rib 1621. In this way, by cooperating with the second extension wall 1512 and the second latch 1511, respectively engaging with the upper and lower sides of the second limiting rib 1621, the connection reliability between the second connector 151 and the second mounting port 162 of the mounting base 16 can be improved. When the second connector 151 rotates relative to the second mounting port 162, the second extension wall 1512 can rotatably abut against the top side of the second limiting rib 1621, and the second buckle 1511 can rotatably engage with the bottom side of the second limiting rib 1621, thereby maintaining the rotatable connection between the second connector 151 and the second mounting port 162, ensuring the connection stability and reliability of the air outlet duct 15. The air conditioner of this embodiment can also be used to solve the problems of drainage blockage in the drip tray and condensate splashing from the evaporator outlet pipe.

[0176] To address the aforementioned problems, as shown in Figures 1 and 2, some embodiments of the present disclosure provide an air conditioner that may include a housing 1. The housing 1 may be configured as the outer casing of the air conditioner.

[0177] As shown in Figures 3 and 4, in some embodiments, the air conditioner may include a refrigerant circulation loop. The refrigerant circulation loop may be located within the casing 1. The refrigerant circulation loop may be located within the accommodating space 10. The refrigerant circulation loop may include a compressor 21, an outdoor heat exchanger 22, and an indoor heat exchanger 23 connected end-to-end. The refrigerant circulates within the refrigerant circulation loop formed by the compressor 21, the outdoor heat exchanger 22, and the indoor heat exchanger 23. During the refrigerant circulation process, the outdoor heat exchanger 22 and the indoor heat exchanger 23 can respectively function as a condenser and an evaporator, allowing the refrigerant to absorb heat through evaporation in the evaporator and release heat through condensation in the condenser, thereby executing either a cooling cycle or a heating cycle for the air conditioner.

[0178] As shown in Figures 2, 3, and 4, in some embodiments, the air conditioner may include an outdoor fan assembly 3. The outdoor fan assembly 3 may be arranged opposite to the outdoor heat exchanger 22. The outdoor fan assembly 3 can be used to introduce outdoor air into the casing 1 for heat exchange with the outdoor heat exchanger 22, forming a heat exchange airflow.

[0179] As shown in Figures 1, 2, and 3, in some embodiments, the air conditioner may include an indoor fan assembly 4. The indoor fan assembly 4 may be arranged opposite to the indoor heat exchanger 23. The indoor fan assembly 4 can be used to introduce indoor air into the casing 1 for heat exchange with the indoor heat exchanger 23, forming a heat exchange airflow.

[0180] As shown in Figures 3 and 4, in some embodiments, the air conditioner may include a second drip tray 5. The outdoor heat exchanger 22 may be positioned above the second drip tray 5. The second drip tray 5 can be used to collect condensate flowing down the outer wall of the outdoor heat exchanger 22.

[0181] As shown in Figures 3 and 4, in some embodiments, the air conditioner may include a first drip tray 6. The first drip tray 6 may be disposed inside the casing 1. The indoor heat exchanger 23 may be disposed above the first drip tray 6. The first drip tray 6 may be used to collect condensate flowing down the outer wall of the indoor heat exchanger 23.

[0182] In some embodiments, the indoor fan assembly 4 may be disposed above the first drip tray 6. The indoor fan assembly 4 may be disposed on one side of the indoor heat exchanger 23 laterally. The first drip tray 6 can be used to provide installation space for the indoor fan assembly 4, so that the indoor fan assembly 4 and the indoor heat exchanger 23 are arranged laterally adjacent to each other, thereby enabling the indoor air introduced by the indoor fan assembly 4 to exchange heat with the indoor heat exchanger 23 nearby, which is beneficial to improving the heat exchange efficiency of the indoor heat exchanger 23.

[0183] As shown in Figures 26, 27, and 28, in some embodiments, the first water receiving tray 6 can be disposed above the top surface of the outdoor heat exchanger 22. The bottom surface of the first water receiving tray 6 can abut against the top surface of the outdoor heat exchanger 22. In this way, the first water receiving tray 6 can be simultaneously supported above the support member 7 and the top of the outdoor heat exchanger 22, improving the stability of the first water receiving tray 6.

[0184] It should be noted that in some other embodiments, there may also be 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.

[0185] As shown in Figures 26 and 27, in some embodiments, the top of the outdoor heat exchanger 22 can abut against the bottom surface of the first water receiving tray 6, and the bottom of the outdoor heat exchanger 22 can be supported on the second water receiving tray 5. This allows the outdoor heat exchanger 22 to be held in the area between the first water receiving tray 6 and the second water receiving tray 5, improving the reliability and structural stability of the outdoor heat exchanger 22.

[0186] As shown in Figures 27 and 30, in some embodiments, an outlet 611 may be provided on the inner bottom surface of the first water receiving tray 6. The outlet 611 may be located above the outdoor heat exchanger 22 and the second water receiving tray 5. The outlet 611 may be located above the top surface of the outdoor heat exchanger 22. The condensate in the first water receiving tray 6 can flow downward through the outlet 611, onto the top surface of the outdoor heat exchanger 22, and flow downward along the outer wall of the outdoor heat exchanger 22, thereby cooling the outdoor heat exchanger 22. Finally, the condensate flows into and is collected in the second water receiving tray 5. In this way, the condensate in the first water receiving tray 6 can be discharged into the second water receiving tray 5 for collection, and heat exchange can be performed between the condensate and the outdoor heat exchanger 22 to cool the outdoor heat exchanger 22. For example, when the air conditioner is cooling, the outdoor heat exchanger 22, acting as a condenser, needs to dissipate heat to the outside, while the indoor heat exchanger 23, acting as an evaporator, needs to absorb heat to the outside. Air condenses into condensate on the surface of the indoor heat exchanger 23. The condensate can flow along the surface of the indoor heat exchanger 23 into the first water collection pan 6, and then through the outlet 611 of the first water collection pan 6 to the outer wall of the outdoor heat exchanger 22, dissipating heat and cooling the outdoor heat exchanger 22. Finally, it flows down the outer wall of the outdoor heat exchanger 22 into the second water collection pan 5 for collection.

[0187] As shown in Figures 28 and 30, in some embodiments, a first water receiving trough 61 may be provided on the top surface of the first water receiving tray 6. The indoor heat exchanger 23 may be located above the first water receiving trough 61. The water outlet 611 may be located on the bottom surface of the first water receiving trough 61. In this way, the condensate formed on the indoor heat exchanger 23 can fall downward into the first water receiving trough 61 and be discharged downward through the water outlet 611.

[0188] As shown in Figures 28 and 30, in some embodiments, a second water receiving trough 53 may be provided on the top surface of the second water receiving tray 5. The outdoor heat exchanger 22 may be located above the second water receiving tray 5. The water outlet 611 may be located above the second water receiving trough 53. The drain outlet 51 may be connected to the second water receiving trough 53. In this way, the water discharged downward from the water outlet 611 can flow through the outdoor heat exchanger 22 and finally fall downward into the second water receiving trough 53, making it easy to collect in the second water receiving trough 53, or be discharged through the drain outlet 51.

[0189] As shown in Figures 27 and 28, in some embodiments, a water-spraying wheel 54 may be provided on the second water receiving tray 5. The water-spraying wheel 54 can be rotatably disposed in the second water receiving trough 53. When the water-spraying wheel 54 rotates, it can lift the condensate in the second water receiving trough 53, causing the condensate to splash onto the surface of the outdoor heat exchanger 22, thereby cooling the surface of the outdoor heat exchanger 22. Under the action of gravity, the condensate flows downward along the surface of the outdoor heat exchanger 22 and then falls back into the second water receiving trough 53. The water-spraying wheel 54 can then lift the condensate in the second water receiving trough 53 again, and this process is repeated. This achieves self-treatment of the condensate in the second water receiving trough 53 and improves the heat exchange efficiency of the outdoor heat exchanger 22.

[0190] As shown in Figures 27 and 28, in some embodiments, the outdoor heat exchanger 22 may include a first heat exchange element 221 and a second heat exchange element 222. The first heat exchange element 221 and the second heat exchange element 222 may be arranged laterally at a distance. The first heat exchange element 221 and the second heat exchange element 222 may be respectively disposed above the second water receiving tank 53. A water agitator 54 may be disposed at the bottom of the space between the first heat exchange element 221 and the second heat exchange element 222. Thus, when the water agitator 54 rotates, it can raise the condensate in the second water receiving tank 53, causing the condensate to splash onto the surfaces of the first heat exchange element 221 and the second heat exchange element 222, thereby increasing the contact area between the condensate and the outdoor heat exchanger 22 and further improving the heat exchange efficiency of the outdoor heat exchanger 22.

[0191] As shown in Figures 27 and 28, in some embodiments, the second water receiving tray 5 may be equipped with a water-pumping drive component 55. The output shaft of the water-pumping drive component 55 may be connected to the water-pumping wheel 54 for transmission. The water-pumping drive component 55 can be used to drive the water-pumping wheel 54 to rotate within the second water receiving trough 53.

[0192] As shown in Figures 29 and 30, in some embodiments, the first water receiving tank 61 may have an outlet end 610. The outlet 611 is located on the bottom surface of the outlet end 610. The outlet end 610 of the first water receiving tank 61 may be located at the lowest point of the first water receiving tank 61. In this way, condensate dripping onto the first water receiving tank 61 can automatically flow to its outlet end 610, allowing the condensate to be smoothly discharged through the outlet 611, thus improving the drainage efficiency of the first water receiving tank 61.

[0193] As shown in Figure 30, in some embodiments, the first water receiving trough 61 can be elongated. The two opposite ends of the first water receiving trough 61 can be a first end 61a and a second end 61b, respectively. The first end 61a and the second end 61b of the first water receiving trough 61 can be located at opposite ends along the length of the first water receiving trough 61. The water outlet 610 of the first water receiving trough 61 can be located at either the first end 61a or the second end 61b. Specifically, when the water outlet 610 of the first water receiving trough 61 is located at the first end 61a, the first end 61a can be the lowest point of the first water receiving trough 61, and the water outlet 611 can be located on the bottom surface of the first end 61a, as shown in Figure 10. When the water outlet 610 of the first water receiving trough 61 is located at the second end 61b, the second end 61b can be the lowest point of the first water receiving trough 61, and the water outlet 611 can be located on the bottom surface of the second end 61b.

[0194] It should be noted that in some other embodiments, the water outlet 610 of the first water receiving tank 61 may also be located in the middle of the first water receiving tank 61 or at other locations.

[0195] As shown in Figures 30 and 31, in some embodiments, a water-guiding slope 612 may be provided on the bottom surface of the first water receiving tank 61. The water-guiding slope 612 may be arranged inclined downwards towards the outlet end 610. In this way, the condensate in the first water receiving tank 61 can flow along the water-guiding slope 612 towards the outlet end 610 and flow to the outlet 611, thereby improving the drainage efficiency of the first water receiving tank 61.

[0196] As shown in Figures 30, 31, and 32, in some embodiments, the outlet end 610 of the first water receiving tank 61 may be provided with multiple water outlets 611, which are arranged sequentially adjacent to each other and separated. Separating ribs 613 may be provided between adjacent water outlets 611. Multiple separating ribs 613 may be provided, and they may be sequentially arranged between two adjacent water outlets 611. In this way, the separating ribs 613 can be used to sequentially separate the multiple water outlets 611, making the multiple water outlets 611 sequentially adjacent to each other and separated.

[0197] As shown in Figures 30, 31, and 32, in some embodiments, the partition rib 613 may protrude from the top opening of the outlet 611. The partition rib 613 may also protrude from the bottom surface of the outlet end 610 of the first water receiving tank 61. One end of the partition rib 613 may extend towards the water guiding slope 612. Adjacent partition ribs 613 may form a water guiding channel 614, one end of which may be connected to a corresponding outlet 611. Multiple partition ribs 613 may form multiple water guiding channels 614, which may be connected to multiple corresponding outlets 611. In this way, multiple water guiding channels 614 can be formed on the bottom surface of the outlet end 610 of the first water receiving tank 61, so that the condensate flowing from the first water receiving tank 61 to the outlet end 610 can be diverted and discharged through different water guiding channels 614 and corresponding outlets 611. The condensate can be separated independently when entering the corresponding outlets 611, which helps to ensure smooth water flow from each outlet 611, thereby improving the smoothness and efficiency of water flow from the first water receiving tank 61.

[0198] As shown in Figures 31, 32, and 33, in some embodiments, the outlet 611 can be a non-circular hole. The shape of the outlet 611 can be non-circular. Thus, by making the outlet 611 a non-circular hole, the non-circular hole can disrupt the surface tension of the condensate when it passes through the outlet 611, improving the flow of water from the outlet 611 and thus increasing the water flow rate and efficiency of the first water receiving tank 61.

[0199] As shown in Figure 32, in some embodiments, a drainage groove 615 can be formed on the side edge of the outlet 611 near the guide slope 612. The width of the drainage groove 615 gradually increases in the direction from the guide slope 612 towards the outlet 611. For example, the drainage groove 615 can have a V-shaped groove structure. The tip of the V-shaped groove structure can be arranged towards the guide slope 612. Thus, by providing the drainage groove 615 on the side edge of the outlet 611, the outlet 611 forms a non-circular hole structure, which helps to break the surface tension of the condensate flowing through the outlet 611, improving the drainage speed and water discharge efficiency of the outlet 611. When the condensate from the first water receiving tank 61 flows to the outlet 611 through the guide slope 612, the condensate can preferentially contact the side of the outlet 611 where the guide channel 615 is located, and flow down along the wall of the guide channel 615 into the outlet 611, thereby improving the flow of water from the outlet 611.

[0200] It should be noted that in some other embodiments, the outlet 611 may also adopt a non-circular hole structure of other shapes.

[0201] As shown in Figure 33, in some embodiments, the top side of the diversion channel 615 is arranged inclined downwards away from the water guiding slope 612. When the condensate from the first water receiving tank 61 flows from the water guiding slope 612 to the outlet 611, the condensate from the first water receiving tank 61 can flow downwards along the wall of the diversion channel 615 into the outlet 611, improving the smoothness and efficiency of the water flow from the outlet 611.

[0202] It should be noted that in some embodiments, the top side surface of the drainage groove 615 can be a flat inclined surface structure, or the top side surface of the drainage groove 615 can be a smooth arc surface structure.

[0203] As shown in Figures 33 and 34, in some embodiments, a recessed cavity 62 may be provided on the bottom surface of the first water receiving tray 6. The recessed cavity 62 may be located above the top surface of the outdoor heat exchanger 22. The water outlet 611 may be located on the top side wall of the recessed cavity 62. Thus, through the structural design of the recessed cavity 62, the distance between the water outlet 611 and the top surface of the outdoor heat exchanger 22 can be increased, allowing the water outlet 611 to float above the top surface of the outdoor heat exchanger 22. When the condensate in the first water receiving tray 6 flows downward through the water outlet 611, the condensate needs to flow through the recessed cavity 62 before flowing onto the top surface of the outdoor heat exchanger 22. Since the recessed cavity 62 is located between the outlet 611 and the top surface of the outdoor heat exchanger 22, it is difficult for dust or dirt in the condensate to clog the recessed cavity 62. Therefore, the problem of easy clogging of the outlet 611 can be effectively solved, ensuring smooth drainage of the outlet 611 of the first water receiving pan 6, thereby improving the drainage efficiency and drainage performance of the first water receiving pan 6.

[0204] As shown in Figures 33 and 34, in some embodiments, the distance h1 between the lower end of the outlet 611 and the top surface of the outdoor heat exchanger 22 can be greater than 1.5 mm. When the clearance cavity 62 has sufficient height, the distance h1 between the lower end of the outlet 611 and the top surface of the outdoor heat exchanger 22 can be greater than 1.5 mm. This maintains a sufficient distance between the outlet 611 and the top surface of the outdoor heat exchanger 22, preventing dust or dirt in the condensate from clogging the space between them, thus effectively solving the problem of easy clogging of the outlet 611. Conversely, if the distance h1 between the lower end of the outlet 611 and the top surface of the outdoor heat exchanger 22 is less than 1.5 mm, a sufficient distance cannot be guaranteed between them.

[0205] As shown in Figures 33 and 34, in some embodiments, a downwardly protruding flange 621 may be provided on the top sidewall of the recessed cavity 62. The flange 621 may be located at the side edge of the lower port of the outlet 611. Thus, by providing the flange 621 at the side edge of the lower port of the outlet 611, so that the bottom end of the flange 621 is lower than the top sidewall of the recessed cavity 62, when water is drained downwards from the outlet 611, the condensate can flow downwards along the sidewall of the outlet 611 and drip from the bottom surface of the flange 621. The condensate is unlikely to climb over the flange 621 to the top sidewall of the recessed cavity 62 and then flow out through other sidewalls of the recessed cavity 62, thereby effectively solving and preventing the problem of water seepage from the outlet 611 to other areas of the outer wall of the water receiving tray.

[0206] As shown in Figures 32, 33, and 34, in some embodiments, the flange 621 can be located below the drainage channel 615. The flange 621 can extend downward from the wall of the drainage channel 615. Thus, by extending downward from the wall of the drainage channel 615, the flange 621 can overlap below the drainage channel 615, making its outline shape similar to that of the drainage channel 615. When the condensate from the first water receiving tray 6 is discharged through the outlet 611, the condensate can smoothly flow downward along the wall of the drainage channel 615 and the side wall of the flange 621, improving the water outlet speed and efficiency of the outlet 611.

[0207] It should be noted that in some other embodiments, the flange 621 may also extend to other side edges of the outlet 611 outside the channel wall of the diversion channel 615.

[0208] As shown in Figures 32, 33, and 34, in some embodiments, the height h2 of the flange 621 can be greater than 1 mm. Thus, by ensuring the height h2 of the flange 621 is greater than 1 mm, the height difference between the bottom surface of the flange 621 and the top sidewall of the clearance cavity 62 is greater than 1 mm. This effectively increases the difficulty for condensate to climb onto the top sidewall of the clearance cavity 621, effectively ensuring that condensate drips from the bottom surface of the flange 621 and preventing condensate from flowing out through other sidewalls of the clearance cavity 62. Conversely, if the height h2 of the flange 621 is less than 1 mm, it cannot be guaranteed that condensate will not climb onto the top sidewall of the clearance cavity 62.

[0209] As shown in Figures 32, 33, and 34, in some embodiments, at the outlet 611, the bottom of the partition 613 is connected to the flange 621. Thus, at the outlet 611, the bottom of the partition 613 can serve as part of the side edge of the outlet 611, allowing condensate to flow smoothly down the side wall of the partition 613 and drip from its bottom end when discharged through the outlet 611.

[0210] As shown in Figure 33, in some embodiments, at the water outlet 611, a water-blocking groove 616 may be recessed on the bottom surface of the end of the partition rib 613 away from the flange rib 621. A water-guiding slope 6161 may be formed on the side of the water-blocking groove 616 near the flange rib 621. The water-guiding slope 6161 may be arranged inclined downwards towards the flange rib 621. In this way, by combining the water-blocking groove 616 with the water-guiding slope 6161, the width of the water-blocking groove 616 can gradually increase from top to bottom. When condensate is discharged through outlet 611, it can flow smoothly down the side of the guide slope 6161 toward the side near the flange 621. Only a small portion of the condensate will cross the water-blocking groove 616 and flow down the side of the water-blocking groove 616 away from the guide slope 6161. Therefore, the condensate can be concentrated on the side of the flange 621 and flow down, improving the drainage smoothness of outlet 611.

[0211] It should be noted that in some embodiments, the water guiding slope 6161 can be a straight slope structure, or the water guiding slope 6161 can be a smooth arc structure.

[0212] As shown in Figures 32, 33, and 34, in some embodiments, the first drip tray 6 may be provided with a drip collection area 63. The drip collection area 63 may be located on the top surface of the first drip tray 6. The drip collection area 63 may be located in an area other than the first drip trough 61. The drip collection area 63 may be located below the outer wall of the indoor fan assembly 4. Condensate on the outer wall of the indoor fan assembly 4 can flow downwards into the drip collection area 63 and be collected there.

[0213] As shown in Figures 32, 33, and 34, in some embodiments, the water receiving area 63 can be connected to the first water receiving tank 61. A connecting channel 64 can be provided between the water receiving area 63 and the first water receiving tank 61. One end of the connecting channel 64 can be connected to the water receiving area 63, and the other end of the connecting channel 64 can be connected to the first water receiving tank 61. In this way, condensate in the water receiving area 63 can enter the first water receiving tank 61 through the connecting channel 64 and be discharged downward through the outlet 611.

[0214] As shown in Figures 32, 33, and 34, in some embodiments, the connecting channel 64 can be located between the outlet end 610 of the first water receiving tank 61 and the water receiving area 63. One end of the connecting channel 64 can be connected to the water receiving area 63. The other end of the connecting channel 64 can be connected to any outlet 611 of the outlet end 610. Since the condensate on the outer wall of the indoor fan assembly 4 is less than the condensate on the indoor heat exchanger 23, the condensate in the water receiving area 63 will be significantly less than the condensate in the first water receiving tank 61. By connecting the water receiving area 63 to any outlet 611 through the connecting channel 64, the condensate in the water receiving area 63 can be discharged through the connecting channel 64 and the outlet 611, ensuring the drainage efficiency of the water receiving area 63.

[0215] It should be noted that in some other embodiments, one end of the water receiving area 63 may also be connected to any number of water outlets 611.

[0216] As shown in Figures 35 and 36, in some embodiments, the indoor heat exchanger 23 may have an outlet pipe 231. The outlet pipe 231 may be arranged in a top-to-bottom direction. The outlet end of the indoor heat exchanger 23 may communicate with the upper end of the outlet pipe 231. The lower end of the outlet pipe 231 may extend below the first water receiving tray 6 to facilitate communication with the inlet of the compressor 21.

[0217] As shown in Figures 35 and 36, in some embodiments, the indoor heat exchanger 23 may have multiple outlet ends, which can be combined and connected to the upper end of the outlet pipe 231. The number of outlet ends of the indoor heat exchanger 23 can be adjusted as needed and is not limited here.

[0218] As shown in Figures 35 and 36, in some embodiments, the outlet pipe 231 may include a first pipe section 2311. The first pipe section 2311 may be located above the first drip tray 6. The first pipe section 2311 may extend downward from the outlet end of the indoor heat exchanger 23. In this way, condensate generated on the first pipe section 2311 can flow downward along the first pipe section 2311 and then into the first drip tray 6 below.

[0219] As shown in Figures 35 and 36, in some embodiments, the outlet pipe 231 may include a second pipe section 2312. The second pipe section 2312 may be arranged by bending upwards from the bottom end of the first pipe section 2311, such that the height of the end of the second pipe section 2312 connected to the first pipe section 2311 may be lower than the height of the end of the second pipe section 2312 away from the first pipe section 2311. In this way, condensate generated on the second pipe section 2312 can flow downwards along the second pipe section 2312, flowing to the end of the second pipe section 2312 connected to the first pipe section 2311, and then dripping downwards from the connection point of the first pipe section 2311 and the second pipe section 2312, and then flowing into the first drip tray 6 below.

[0220] As shown in Figures 35 and 36, in some embodiments, a bend 2313 may be formed at the bend connection between the first pipe segment 2311 and the second pipe segment 2312. The bend 2313 may be located at the bottom end of the second pipe segment 2312. Thus, the bend 2313 may be located at the end of the second pipe segment 2312 connected to the first pipe segment 2311, and the end of the second pipe segment 2312 away from the first pipe segment 2311 may be the top end of the second pipe segment 2312. Condensate generated on the second pipe segment 2312 can flow downwards along the outer wall of the second pipe segment 2312, dripping down at the bend 2313, and then flowing into the lower first drip tray 6. Furthermore, condensate generated on the first pipe segment 2311 can flow downwards along the outer wall of the first pipe segment 2311, dripping down at the bend 2313, and then flowing into the lower first drip tray 6.

[0221] As shown in Figures 35 and 36, in some embodiments, the first pipe segment 2311 and the second pipe segment 2312 can each be a straight pipe structure. The first pipe segment 2311 can be a straight pipe structure extending vertically upwards and downwards. The second pipe segment 2312 can be a straight pipe structure extending obliquely upwards and downwards. The bottom ends of the first pipe segment 2311 and the bottom ends of the second pipe segment 2312 can be bent together by a bending portion 2313.

[0222] As shown in Figures 35 and 36, in some embodiments, the outlet pipe 231 may include a third pipe section 2314. The third pipe section 2314 may extend downward from the end of the second pipe section 2312 away from the bend 2313. Condensate generated on the third pipe section 2314 may flow downward along the outer wall of the third pipe section 2314, thereby facilitating flow to the water collection tank of the chassis 12.

[0223] As shown in Figures 35 and 36, in some embodiments, a water-blocking part 411 may be provided on the outer wall of the indoor fan assembly 4. The water-blocking part 411 may be located below the bend 2313. In this way, the condensate generated on the first pipe section 2311 and the second pipe section 2312 can flow downward along the outer wall to the bend 2313, drip down from the bottom of the bend 2313 onto the water-blocking part 411, flow through the water-blocking part 411 to the outer wall of the indoor fan assembly 4, and then flow downward through the outer wall of the indoor fan assembly 4 into the first water receiving tray 6. This can prevent the condensate on the outlet pipe 231 from dripping directly into the first water receiving tray 6, thereby preventing the condensate from splashing out of the water receiving tray and onto the inner wall of the casing 1, and dripping down the inner wall of the casing 1 onto the ground, effectively solving the problem of condensate from the outlet pipe 231 easily splashing out of the water receiving tray.

[0224] As shown in Figures 35 and 37, in some embodiments, the vertical distance L between the bottom end of the water-blocking part 411 and the bottom end of the bending part 2313 can be less than 50 mm. Thus, by making the vertical distance L between the bottom end of the water-blocking part 411 and the bottom end of the bending part 2313 less than 50 mm, the height difference between the bottom end of the water-blocking part 411 and the bottom end of the bending part 2313 can be reduced, effectively preventing condensate dripping from the bottom end of the bending part 2313 from splashing onto the water-blocking part 411, thereby avoiding condensate on the water-blocking part 411 from splashing onto the inner wall of the housing 1.

[0225] It should be noted that the water-blocking part 411 can also contact the bottom end of the bending part 2313. In this case, the vertical distance between the water-blocking part 411 and the bottom end of the bending part 2313 is zero. At this time, the condensate at the bottom end of the bending part 2313 can flow directly onto the water-blocking part 411.

[0226] As shown in Figures 35, 36, and 37, in some embodiments, the top surface of the water-blocking portion 411 may be formed with a water-blocking slope 4111. The bending portion 2313 may be arranged above the water-blocking slope 4111. The water-blocking slope 4111 may be arranged to extend downwards at an angle towards the indoor fan assembly 4. Thus, when condensate on the bending portion 2313 drips onto the water-blocking slope 4111, it flows downwards along the water-blocking slope 4111 towards the indoor fan assembly 4, onto the outer wall of the indoor fan assembly 4, and then smoothly flows downwards along the outer wall of the indoor fan assembly 4 onto the first water receiving tray 6.

[0227] As shown in Figures 35, 36, and 37, in some embodiments, the top of the water-blocking portion 411 may be provided with a stepped portion 4112. The stepped portion 4112 may be located at the end of the water-blocking slope 4111 away from the indoor fan assembly 4. There may be a height difference between the stepped portion 4112 and the top edge of the water-blocking slope 4111. The stepped portion 4112 may be higher than the top edge of the water-blocking slope 4111. In this way, when condensate on the bent portion 2313 drips onto the water-blocking slope 4111, some of the splashed water can be blocked by the stepped portion 4112 and fall back onto the water-blocking slope 4111 along the side wall of the stepped portion 4112, thereby preventing the condensate dripping onto the water-blocking slope 4111 from splashing onto the inner wall of the housing 1.

[0228] As shown in Figures 35 and 36, in some embodiments, a water-blocking rib 4113 extending upward may be provided on the side edge of the water-blocking slope 4111 away from the indoor heat exchanger 23. The water-blocking rib 4113 may be arranged obliquely downward along the side edge of the water-blocking slope 4111. The bottom end of the water-blocking rib 4113 may be connected to the outer wall of the indoor fan assembly 4. The top end of the water-blocking rib 4113 may be connected to the step portion 4112. In this way, the water-blocking rib 4113 can block the water on the side edge of the water-blocking slope 4111 away from the indoor heat exchanger 23. When condensate on the bend portion 2313 drips onto the water-blocking slope 4111, some of the splashed water can be blocked by the water-blocking rib 4113 and fall back onto the water-blocking slope 4111 along the side wall of the water-blocking rib 4113, thereby preventing the condensate dripping onto the water-blocking slope 4111 from splashing onto the inner wall of the casing 1.

[0229] It should be noted that, in some embodiments, when condensate water on the bend 2313 drips onto the water-blocking slope 4111, water splashed towards the side closer to the indoor heat exchanger 23 can flow down along the outer wall of the indoor heat exchanger 23 and then onto the first water receiving tray 6; water splashed towards the side farther from the indoor heat exchanger 23 can be blocked by the water-blocking rib 4113 and fall back onto the water-blocking slope 4111; water splashed towards the side closer to the indoor fan assembly 4 can flow down along the outer wall of the indoor fan assembly 4 and then onto the first water receiving tray 6; water splashed towards the side farther from the indoor fan assembly 4 can be blocked by the step portion 4112 and fall back onto the water-blocking slope 4111. In this way, the water-blocking slope 4111 can, to a certain extent, prevent condensate water dripping onto the water-blocking slope 4111 from splashing onto the casing 1.

[0230] As shown in Figures 36 and 38, in some embodiments, the indoor fan assembly 4 may include an indoor duct housing 41. An indoor duct may be formed inside the indoor duct housing 41. The indoor duct housing 41 may be located on one side of the indoor heat exchanger 23. The indoor heat exchanger 23 may be attached to the outer wall of the indoor duct housing 41. The air inlet of the indoor duct housing 41 may face the indoor heat exchanger 23, and further towards the indoor air inlet 111. The air outlet of the indoor duct housing 41 may face the indoor air outlet 112. Thus, when the indoor fan assembly 4 is running, it draws indoor air into the housing 1 through the indoor air inlet 111, exchanges heat with the indoor heat exchanger 23, and the heat-exchanged air enters the indoor duct housing 41 and is then discharged back into the indoor space outside the housing 1 through the air outlet of the indoor duct housing 41 and the indoor air outlet 112.

[0231] As shown in Figures 36 and 38, in some embodiments, the bottom end of the indoor duct housing 41 can be mounted on the first drip tray 6. A water-blocking portion 411 can be provided on the outer wall of the indoor duct housing 41. Thus, when condensate from the outlet pipe 231 of the indoor heat exchanger 23 drips onto the water-blocking portion 411, it can flow along the water-blocking portion 411 to the outer wall of the indoor duct housing 41, and then flow downwards along the outer wall of the indoor duct housing 41, flowing from the bottom end of the indoor duct housing 41 into the first drip tray 6, thereby effectively preventing condensate from dripping from a height and splashing onto the inner wall of the housing 1.

[0232] As shown in Figures 36 and 38, in some embodiments, the indoor fan assembly 4 may include an indoor impeller 42. The indoor impeller 42 may be rotatably disposed inside the indoor duct housing 41, that is, the indoor impeller 42 may be rotatably disposed inside the indoor duct. When the indoor impeller 42 rotates, wind force can be generated inside the indoor duct housing 41, so that the air in the indoor space can flow through the indoor air outlet 112, pass through the indoor heat exchanger 23, enter the indoor duct housing 41, and then be discharged into the indoor space outside the housing 1 through the air outlet end of the indoor duct housing 41 and the indoor air outlet 112.

[0233] As shown in Figures 36 and 38, in some embodiments, the indoor fan assembly 4 may include an indoor motor 43. The output end of the indoor motor 43 may be connected to the indoor impeller 42 for transmission. The indoor motor 43 may be used to drive the indoor impeller 42 to rotate inside the indoor duct housing 41. When the indoor motor 43 drives the indoor impeller 42 to rotate inside the indoor duct housing 41, wind force can be generated inside the indoor duct housing 41, so that the air in the indoor space can flow through the indoor air outlet 112, pass through the indoor heat exchanger 23, enter the interior of the indoor duct housing 41, and then be discharged into the indoor space outside the housing 1 through the air outlet 112 of the indoor duct housing 41.

[0234] As shown in Figures 36 and 38, in some embodiments, the indoor duct housing 41 and the indoor fan 42 can be arranged to extend vertically. The indoor motor 43 can be located below the bottom of the indoor duct housing 41 and above the first water collection tray 6. In this way, the lateral width of the air conditioner can be reduced, while the longitudinal height of the air conditioner can be increased, which helps to reduce the space occupied by the air conditioner.

[0235] As shown in Figures 30 and 38, in some embodiments, the first water receiving tray 6 may be provided with an installation area 65. A first water receiving trough 61 may be located on one side of the installation area 65. The bottom end of the indoor air duct housing 41 may be installed within the installation area 65. The first end 61a of the first water receiving trough 61 may be arranged on one side of the installation area 65, and the second end 61b of the first water receiving trough 61 may be bent and extended to an adjacent side of the installation area 65. The indoor heat exchanger 23 may extend laterally from the first end 61a of the first water receiving trough 61 to the second end 61b of the first water receiving trough 61, allowing the indoor heat exchanger 23 to be arranged on adjacent lateral sides of the indoor air duct housing 41. In this case, the air inlet end of the indoor air duct housing 41 may be located on adjacent lateral sides of the indoor air duct housing 41, thus facing the indoor heat exchanger 23, which is beneficial to the air intake efficiency of the indoor fan assembly 4 and improves the heat exchange efficiency of the indoor heat exchanger 23.

[0236] As shown in Figures 30 and 38, in some embodiments, the first water receiving tray 6 may be provided with a mounting position 651. The mounting position 651 may be located within the mounting area 65. The indoor motor 43 may be installed in the mounting position 651. The mounting position 651 may be isolated from the first water receiving tank 61 and the water receiving area 63, thereby preventing condensate from entering the mounting position 651 and the indoor motor 43, and preventing condensate from entering the indoor motor 43 and affecting its normal operation.

[0237] As shown in Figures 3 and 4, in some embodiments, a fixing rod 114 may be provided inside the housing 1. The fixing rod 114 may be located inside the main housing 11. The fixing rod 114 may extend vertically.

[0238] As shown in Figures 3 and 35, the water-blocking part 411 can be fixed to the fixing rod 114. In this way, one side of the outdoor air duct housing 30 can be fixed to the fixing rod 114 through the water-blocking part 411, thereby improving the structural stability of the water-blocking part 411 and the outdoor air duct housing 30.

[0239] The air conditioner disclosed in this embodiment can also be used to solve the problem of water discharge efficiency of the drip tray. In related air conditioners, the water discharge efficiency of the drip tray inside the air conditioner is low, the water in the drip tray flows to the outlet slowly, and the water in the drip tray is prone to accumulate and cannot be discharged in time. This will affect the operation of the heat exchanger and may even cause the air conditioner to leak.

[0240] To solve the above problems, as shown in Figures 39 and 40, the air conditioner of this embodiment can operate independently. The air conditioner may be equipped with a compressor 21, an expansion valve, an outdoor heat exchanger 22, an indoor heat exchanger 23, an outdoor air duct housing 30, an outdoor fan 310, an indoor air duct housing 40, and an indoor fan 410, etc.

[0241] As shown in Figure 39, in some embodiments, the outdoor fan 310 is disposed in the outdoor duct housing 30, which can limit the flow path of the air inside. The operation of the outdoor fan 310 can introduce air into the housing 1 through the outdoor duct housing 30, and form a heat exchange airflow through heat exchange with the refrigerant in the outdoor heat exchanger 22.

[0242] As shown in Figure 40, in some embodiments, the indoor fan 410 is disposed in the indoor duct housing 40, which can define the flow path of the air inside. The operation of the indoor fan 410 can introduce air into the housing 1 through the indoor duct housing 40, and form a heat exchange airflow through heat exchange with the refrigerant in the indoor heat exchanger 23.

[0243] The outdoor heat exchanger 22 can be an evaporator or a condenser, and the corresponding indoor heat exchanger 23 can be a condenser or an evaporator. The air conditioner performs the refrigeration cycle or heating cycle by using the compressor 21, expansion valve, condenser and evaporator.

[0244] As shown in Figures 39 and 40, the casing 1 includes a main casing 11 and a chassis 12. The main casing 11 and the chassis 12 form an internal accommodating space 10, which is suitable for accommodating the refrigerant circulation loop 20 of the air conditioner and provides a stable and reliable installation position for the refrigerant circulation loop 20 within the air conditioner. The refrigerant circulation loop 20 includes a compressor 21, an outdoor heat exchanger 22, and an indoor heat exchanger 23 connected end-to-end, thus allowing the refrigerant to form a flow loop between the compressor 21, the outdoor heat exchanger 22, and the indoor heat exchanger 23.

[0245] Referring to Figures 39 and 40, in some embodiments, an air inlet pipe 14 and an air outlet pipe 15 are provided outside the housing 10. Outdoor air can enter the housing 10 through the air inlet pipe 14, exchange heat with the outdoor heat exchanger 22, and then enter the outdoor air duct housing 30. Under the acceleration of the outdoor fan 310, it flows out from the outdoor air duct housing 30 to the air outlet pipe 15, and then flows to the outside from the air outlet pipe 15.

[0246] Referring to Figures 41, 42, and 43, in some embodiments, the air conditioner further includes a first drip tray 6, which is disposed within the receiving space 10. The first drip tray 6 can be connected to the main casing 11. The first drip tray 6 is located below the indoor heat exchanger 23 and is used to collect the condensate formed by the indoor heat exchanger 23 exchanging heat with the indoor air. The outdoor heat exchanger 22 is located below the first drip tray 6. The first drip tray 6 is provided with a first drip groove 61 and a first drain outlet 601, which are connected. Specifically, condensate will condense on the surface of the indoor heat exchanger 23 during heat exchange, and the first drip tray 6 is disposed below the indoor heat exchanger 23. The condensate will flow into the first water receiving trough 61 of the first water receiving pan 6 under the action of gravity, and then flow out through the outlet end of the first water receiving trough 61 to the first water outlet 601, and finally flow out to the outside from the first water outlet 601, thereby realizing the discharge of condensate in the first water receiving pan 6.

[0247] Referring to Figures 42 and 43, in some embodiments, the outlet ends of the first water outlet 601 and the first water receiving trough 61 are spaced apart, and multiple partition ribs 613 are provided between the outlet ends of the first water outlet 601 and the first water receiving trough 61. A water guiding channel 614 is formed between two adjacent partition ribs 613. There are multiple first water outlets 601 and multiple water guiding channels 614. The inlet ends of the multiple water guiding channels 614 are connected to the outlet ends of the first water receiving trough 61, and the outlet ends of the multiple water guiding channels 614 are connected to multiple first water outlets 601 in a one-to-one correspondence. Specifically, by spaced apart the outlet ends of the first water outlet 601 and the first water receiving trough 61, and by providing multiple partition ribs 613 between the outlet ends of the first water outlet 601 and the first water receiving trough 61, a water guiding channel 614 is defined between two adjacent partition ribs 613, and there are multiple water guiding channels 614.

[0248] By connecting multiple water guiding channels 614 and multiple first water outlets 601 in a one-to-one correspondence, condensate can flow out from the outlet of the first water receiving tank 61 and enter the multiple water guiding channels 614, and then enter the multiple first water outlets 601, thus allowing the condensate to flow out from the multiple first water outlets 601. This arrangement increases the water output of the first water receiving pan 6 per unit time through the multiple first water outlets 601, and improves the smoothness of condensate flow through the multiple water guiding channels 614, thereby enhancing the water output efficiency of the first water receiving pan 6.

[0249] Therefore, multiple water guiding channels 614 are defined by multiple partition ribs 613, and each of the multiple water guiding channels 614 corresponds one-to-one with a multiple first water outlet 601. This allows water flowing from the outlet end of the first water receiving tank 61 to be guided to the multiple first water outlets 601 through the multiple water guiding channels 614, thereby increasing the water output per unit time of the first water receiving tray 6 and improving the smoothness of water flow, thus improving the water output efficiency of the first water receiving tray 6.

[0250] Referring to Figures 42 and 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 tank 61, and multiple partition ribs 613 are provided on the water guiding slope 6161. The water guiding slope 6161 is inclined from top to bottom, and the first water outlet 601 is provided at the lower end of the water guiding slope 6161.

[0251] As shown in Figure 43, in some embodiments, a water-guiding slope 6161 is provided between the first water outlet 601 and the outlet end of the first water receiving tank 61, and multiple partition ribs 613 are disposed in the water-guiding slope 6161, with the water-guiding slope 6161 inclined in a downward direction. After the condensate flows out from the outlet end of the first water receiving tank 61 into the water guiding channel 614, the water flow will continuously accelerate under the action of gravity due to the inclined arrangement of the water-guiding slope 6161. This allows the water flow velocity in the water guiding channel 614 to gradually increase, and it can quickly flow to the first water outlet 601 and flow out from the first water outlet 601, thus further improving the water discharge efficiency of the first water receiving tray 6.

[0252] Referring to Figures 42 and 43, in some embodiments, a second outlet 602 is provided on the first water receiving tray 6, and the second outlet 602 is spaced apart on the outside of the plurality of partition ribs 613. Specifically, by providing the second outlet 602 on the first water receiving tray 6, when too much water flows from the water guiding channel 614 to the first outlet 601 and the first outlet 601 cannot discharge it in time, the water will overflow to the outside of the plurality of partition ribs 613, thus entering the second outlet 602 and flowing out from the second outlet 602. This can further improve the reliability of drainage of the first water receiving tray 6 and optimize the structural design of the first water receiving tray 6.

[0253] Referring to Figures 42 and 43, in some embodiments, the water receiving tray contains a first water receiving trough 61, a water guiding slope 6161 is located on one side of the first water receiving trough 61, a first water outlet 601 is located at the bottom of the first water receiving trough 61, and a second water outlet 602 is also located at the bottom of the first water receiving trough 61. Multiple dividing ribs 613 are provided on the water guiding slope 6161. When excessive water flows into the first water receiving trough 61 through the water guiding slope 6161, and the first water outlet 601 cannot discharge it in time, the water level will be higher than the height of the multiple dividing ribs 613, causing water to overflow from the multiple dividing ribs 613 and flow towards the second water outlet 602, which is also located at the bottom of the first water receiving trough 61, and then flow out from the second water outlet 602.

[0254] As shown in Figures 42 and 43, the diameter of the second outlet 602 can be larger than the diameter of the first outlet 601.

[0255] Referring to Figures 42 and 43, there can be one second water outlet 602, and the diameter of the second water outlet 602 is set to be larger than the diameter of a single first water outlet 601. This can improve the water discharge efficiency of the second water outlet 602 while facilitating the manufacture of the first water receiving tray 6, thereby further improving the water discharge efficiency of the first water receiving tray 6.

[0256] As shown in Figure 41, in some embodiments, the air conditioner may further include a second drip tray 5. The second drip tray 5 is located below the outdoor heat exchanger 22, and the compressor 21 is located below the second drip tray 5.

[0257] As shown in Figure 41, in some embodiments, the air conditioner may further include a water pumping device 510. The water pumping device 510 includes a water pumping wheel 54 and a water pumping drive 55. The water pumping wheel 54 is rotatably disposed on the second water receiving tray 5, and the water pumping drive 55 is disposed on the second water receiving tray 5 and is drivenly connected to the water pumping wheel 54.

[0258] As shown in Figure 41, in some embodiments, the outdoor heat exchanger 22 includes a first heat exchange element 221 and a second heat exchange element 222. The first heat exchange element 221 and the second heat exchange element 222 are spaced apart to form a water flow channel 24, and a water jet 54 is correspondingly disposed at the lower end of the water flow channel 24. Specifically, by placing the second water receiving tray 5 below the outdoor heat exchanger 22, condensate will be generated on the surface of the outdoor heat exchanger 22 during the heat exchange process. The condensate will flow to the second water receiving tray 5 under the action of gravity. By setting the water jet 54 and the water jet driving component 55 on the second water receiving tray 5, and by driving the water jet 54 to rotate, the rotation of the water jet 54 can splash water in the second water receiving tray 5 and cool the surface of the indoor heat exchanger 23. In this way, the water in the second water receiving tray 5 can be self-treated, and the heat exchange efficiency of the indoor heat exchanger 23 can be improved.

[0259] Furthermore, the first heat exchanger 221 and the second heat exchanger 222 are spaced apart to form a water flow channel 24. Water on the outdoor heat exchanger 22 can flow through the water flow channel 24 to the water impeller 54, and water on the first water receiving tray 6 can also flow through the water flow channel 24 to the water impeller 54 after flowing out of the first outlet 601. This not only ensures the smooth flow of water from the outdoor heat exchanger 22 to the second water receiving tray 5, but also ensures the smooth flow of water from the first water receiving tray 6 to the second water receiving tray 5.

[0260] It should be noted that when the outdoor heat exchanger 22 is a condenser, the first heat exchange element 221 is a single-row condenser and the second heat exchange element 222 is a triple-row condenser. This ensures the heat exchange efficiency of the outdoor heat exchanger 22 while ensuring the smooth flow of water through the water channel 24.

[0261] Referring to Figures 44 and 45, in some embodiments, the air conditioner further includes a sealing plate 66. The sealing plate 66 covers the upper side of the outdoor heat exchanger 22, and a guide groove 661 is provided on the sealing plate 66, corresponding to and communicating with the water flow channel 24. Specifically, the sealing plate 66 covers the upper side of the outdoor heat exchanger 22, and the guide groove 661 is provided on the sealing plate 66, corresponding to the water flow channel 24. The sealing plate 66, together with the first drip tray 6, provides protection for the upper part of the outdoor heat exchanger 22. Furthermore, since the sealing plate 66 is close to the outdoor heat exchanger 22, condensate will condense on its surface. Therefore, the guide groove 661 on the sealing plate 66 allows the condensate to flow to the water flow channel 24 under the guidance of gravity and the guide groove 661. This allows the condensate to flow through the water flow channel 24 to the second drip tray 5, further optimizing the structural performance of the air conditioner.

[0262] Referring to Figures 44 and 45, in some embodiments, the cross-section of the guide groove 661 in the vertical direction is an inverted V-shape, and the cross-sectional area of ​​the guide groove 661 in the horizontal direction gradually increases from top to bottom. Specifically, by setting the cross-section of the guide groove 661 in the vertical direction to an inverted V-shape, the cross-sectional area of ​​the guide groove 661 in the horizontal direction gradually increases from top to bottom. This makes the guidance of condensate water by the guide groove 661 more stable and smooth, and makes the flow of condensate water to the water flow channel 24 more uniform, which can further improve the guiding effect of the guide groove 661 and optimize the structural design of the sealing plate 66.

[0263] Referring to Figures 44 and 45, in some embodiments, the inner wall of the guide groove 661 is provided with multiple guide ribs 662, and a guide channel 663 is formed between two adjacent guide ribs 662. There are multiple guide channels 663, and each guide channel 663 is correspondingly connected to the water flow channel 24. Specifically, by providing multiple guide ribs 662 in the guide groove 661 and forming a guide channel 663 between two adjacent guide ribs 662, not only can the guidance of condensate water by the guide groove 661 be made more stable and smooth, but the structure of the guide groove 661 can also be simplified, thereby further optimizing the structural design of the sealing plate 66.

[0264] As shown in Figure 44, in some embodiments, the sealing plate 66 and the first drip tray 6 are integrally formed structural components. Specifically, setting the sealing plate 66 and the first drip tray 6 as integrally formed structural components not only simplifies the installation steps of the sealing plate 66 and the first drip tray 6 in the receiving space 10, but also improves the stability of the connection between the sealing plate 66 and the first drip tray 6, thereby improving the structural reliability of the air conditioner.

[0265] As shown in Figure 44, in some embodiments, the sealing plate 66 is detachably connected to the first water receiving tray 6. Specifically, by detachably connecting the sealing plate 66 and the first water receiving tray 6, it is possible to facilitate individual maintenance and replacement of the sealing plate 66 and the first water receiving tray 6 while ensuring the stability of the connection between them.

[0266] Those skilled in the art will understand that the scope of this disclosure is not limited to the specific embodiments described above, and that modifications and substitutions can be made to certain elements of the embodiments without departing from the spirit of this disclosure. The scope of this disclosure is limited by the appended claims.
