[0020] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "support" should be interpreted broadly. For example, they can refer to fixed supports, detachable supports, or integral supports; they can refer to mechanical supports or electrical supports; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] Please see Figures 1 to 2 This application provides an outdoor enclosure 11 for use in an outdoor unit 10.

[0022] This application provides an outdoor unit 10, please refer to... Figure 3 The outdoor unit 10 includes an outdoor heat exchanger 12, an outdoor fan 14, a water spraying component 13, and an outdoor enclosure 11 in any embodiment of this application.

[0023] It is understandable that the outdoor unit 10 can be a separate outdoor air conditioning unit or integrated into a single air conditioning unit; there are no restrictions on this.

[0024] This application provides an air conditioner 100. Please refer to [link / reference]. Figures 5 to 7 The air conditioner 100 includes an indoor unit 20 and an outdoor unit 10 in any embodiment of this application. The indoor unit 20 includes an indoor heat exchanger 21, which is in heat exchange communication with the outdoor heat exchanger 12.

[0025] It is understood that the type of air conditioner 100 in this application is not limited; for example, it can be a window air conditioner. The window air conditioner is an integrated air conditioner, that is, the outdoor unit 10 and the indoor unit 20 are integrated into one box, thus making the structure compact and reducing the space occupied indoors.

[0026] For example, a mounting opening is formed in the wall, a window can be disposed in the mounting opening, and the air conditioner 100 can be installed in the mounting opening. The two sides of the window are the indoor side and the outdoor side, respectively. The indoor unit 20 is located on the indoor side of the window, and the outdoor unit 10 is located on the outdoor side of the window. Of course, the air conditioner 100 can also be installed in other locations that are substantially similar to the window. For example, the air conditioner 100 can be installed on the wall through a housing 40. The housing 40 may include an indoor housing and an outdoor housing. The outdoor housing is disposed outside the outdoor unit 10 and is mounted to the wall, while the indoor housing is disposed outside the indoor unit 20 and is exposed to the external environment.

[0027] For example, the air conditioner 100 can be a PTAC (Packaged Terminal Air Conditioner) window unit, that is, the air conditioner 100 has a fresh air function while cooling and heating, thus improving air quality.

[0028] In some embodiments, please refer to Figures 5 to 7 The air conditioner 100 includes a chassis 30, an outer casing 40, and a partition 50. The outer casing 40 covers the chassis 30. The outdoor unit 10 and the indoor unit 20 are disposed within the space defined by the chassis 30 and the outer casing 40. The partition 50 separates the indoor unit 20 and the outdoor unit 10.

[0029] The chassis 30 is positioned at the bottom of the outdoor unit 10 and the indoor unit 20 to support them. The outer casing 40 covers the chassis 30. Thus, the indoor unit 20 and the outdoor unit 10 are located within the space defined by the chassis 30 and the outer casing 40, providing protection for them and ensuring the overall structural stability of the air conditioner 100, which facilitates its installation. The partition 50 separates the indoor unit 20 and the outdoor unit 10; that is, the indoor unit 20 is located on the side of the partition 50 facing inward, and the outdoor unit 10 is located on the side of the partition 50 facing outward.

[0030] Understandably, without a partition, the cold air drawn in by the indoor fan may leak directly from the casing to the outdoor side, or the hot air drawn in by the outdoor fan may directly enter the indoor side, causing a decrease in the cooling and heating efficiency of the air conditioner and affecting its performance.

[0031] Therefore, the partition 50 is used to isolate indoor and outdoor air, physically blocking the direct connection between the indoor and outdoor air ducts. This ensures that indoor air can only be drawn in by the indoor fan, exchanged heat through the indoor heat exchanger 21, and then blown back indoors; outdoor air can only be drawn in by the outdoor fan 14, exchanged heat through the outdoor heat exchanger 12, and then discharged outdoors. This allows the air conditioner 100 to efficiently complete the heat exchange process of indoor heat absorption and outdoor heat release (cooling) or "outdoor heat absorption and indoor heat release" (heating). Of course, the partition 50 also provides structural support and dust and water protection, reducing the likelihood of rainwater and dust directly entering the indoor side.

[0032] The partition 50 can be a sheet metal part, which is lightweight and high-strength, making it easy to mass-produce and thus ensuring the structural strength of the partition 50.

[0033] The outdoor heat exchanger 12 is used for heat exchange with outdoor air, and the indoor heat exchanger 21 is used for heat exchange with indoor air. Both the indoor heat exchanger 21 and the outdoor heat exchanger 12 function as evaporators or condensers. The working principle of the air conditioner 100 is briefly described below.

[0034] In cooling mode, the outdoor heat exchanger 12 acts as a condenser, and the indoor heat exchanger 21 acts as an evaporator. The compressor draws in low-temperature, low-pressure gaseous refrigerant and compresses it into high-temperature, high-pressure gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant enters the outdoor heat exchanger 12, and the outdoor fan 14 draws in outdoor air. The high-temperature, high-pressure refrigerant exchanges heat with the outdoor air, lowering its temperature and causing it to condense from a gaseous state into a liquid state. At the same time, it releases a large amount of heat to the outdoor air. The high-pressure liquid refrigerant passes through a throttling device and becomes low-temperature, low-pressure liquid refrigerant, which then enters the indoor heat exchanger 21. The indoor fan draws in indoor air, and the low-temperature, low-pressure liquid refrigerant exchanges heat with the indoor air, absorbing heat from the indoor air and evaporating from a liquid state into a gaseous state. Simultaneously, it lowers the indoor air temperature, and the cooled air is blown back into the room, achieving cooling.

[0035] In heating mode, the outdoor heat exchanger 12 is used as an evaporator, and the indoor heat exchanger 21 is used as a condenser. The compressor compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas. The high-temperature, high-pressure gas first enters the room and exchanges heat with the indoor heat exchanger 21. The indoor fan blows through the indoor heat exchanger 21, and the refrigerant releases heat to the indoor air and condenses into a liquid, thus raising the temperature of the indoor air. The high-pressure liquid refrigerant passes through a throttling device and becomes a low-temperature liquid. The low-temperature, low-pressure liquid refrigerant enters the outdoor heat exchanger 12, where it absorbs heat from the outdoor air and evaporates into a gas. In this way, heating is achieved.

[0036] Please see Figures 1 to 4 The outdoor enclosure 11 includes a panel 110, a guide ring 111, a first water guide component 112, and a second water guide component 113.

[0037] Panel 110 is provided with a mounting position for installing outdoor heat exchanger 12.

[0038] Panel 110 serves as the main structure of outdoor enclosure 11, providing support, protection, and integrated installation for outdoor heat exchanger 12, water pump 13, outdoor fan 14, etc.

[0039] The air guide ring 111 is connected to the panel 110. It is understood that the air guide ring 111 can be integrally formed on the panel 110, or it can be formed separately from the panel 110 and then connected. There is no limitation here.

[0040] The guide ring 111 is provided to form an airflow channel 111a, which is used to accommodate at least part of the water pump 13 and the outdoor fan 14.

[0041] Water pumping component 13 is connected to the periphery of outdoor fan 14; water pumping component 13 and outdoor fan 14 are arranged in airflow channel 111a, and water pumping component 13 is used to pump liquid toward outdoor heat exchanger 12.

[0042] It is understood that the air inlet side of the guide ring 111 is the side where the outdoor fan 14 takes in air, and the air outlet side of the guide ring 111 is the side where the outdoor fan 14 exits air. The air inlet side and the air outlet side are located on opposite sides of the guide ring 111 along the axial direction. The airflow channel 111a takes in air from the air inlet side and exits air from the air outlet side. In this application, the air inlet side can be the front side, and the air outlet side can be the rear side. Here, the rear side is the direction facing the outdoor side when the air conditioner 100 is in normal use, and the front side is the direction facing the indoor side when the air conditioner 100 is in normal use.

[0043] The airflow channel 111a can guide the airflow so that when the outdoor fan 14 rotates, the airflow maintains the concentration of wind force in the flow and blows from front to back through the guide ring 111 to the outdoor heat exchanger 12 to achieve heat exchange.

[0044] It is understandable that when the air conditioner 100 is working, the condensate produced by the indoor heat exchanger will flow towards the outdoor side and accumulate. When the outdoor fan 14 rotates, the water pump 13 rotates and drives the condensate upward. The condensate that is lifted drops onto the outdoor heat exchanger 12 to carry away the heat of the outdoor heat exchanger 12, thereby increasing the heat exchange efficiency of the outdoor heat exchanger 12.

[0045] It should be noted that the outdoor unit 10 includes an outdoor water collection pan located below the outdoor heat exchanger 12 to collect the condensate produced by the outdoor heat exchanger 12. The indoor unit 20 includes an indoor water collection pan located below the indoor heat exchanger 21 to collect the condensate produced by the indoor heat exchanger. The indoor and outdoor water collection pans can be an integrated structure or separate structures. The indoor and outdoor water collection pans can be different structures from the chassis 30 or part of the chassis 30; no restrictions are placed here. The condensate produced by the indoor heat exchanger 21 can be guided from the indoor water collection pan to the outdoor water collection pan via a drainage structure. When the outdoor fan 14 rotates, part of the water pump 13 extends into the outdoor water collection pan to drive the condensate upward.

[0046] The outdoor heat exchanger 12 is located on the air outlet side of the panel 110, that is, the outdoor heat exchanger 12 is located on the rear side of the panel 110. For example, the panel 110 is also provided with a motor mounting part. The outdoor unit 10 includes a motor, which is mounted on the motor mounting part through a motor bracket. The motor is located on the air inlet side of the panel 110, that is, the front side. The motor is connected to the outdoor fan 14 and is used to provide driving force for the outdoor fan 14. The outdoor enclosure 11 can provide support for the outdoor heat exchanger 12, the motor, the outdoor fan 14 and the water spraying component 13. At the same time, the positions of the outdoor heat exchanger 12 and the motor relative to the outdoor enclosure 11 are fixed to ensure the heat exchange performance of the outdoor heat exchanger 12.

[0047] For example, the top portion of the outdoor enclosure 11 extends above the outdoor heat exchanger 12. Water agitated by the water pump 13 can then be thrown towards the top of the outdoor enclosure 11, and then, under the influence of wind pressure and gravity, the water falls onto the refrigerant pipes of the outdoor heat exchanger 12 below, resulting in higher heat exchange efficiency.

[0048] The form of the outdoor fan 14 is not limited; it can be an axial flow fan, a centrifugal fan, etc.

[0049] The water spraying component 13 is located on the outer periphery of the outdoor fan 14. The water spraying component 13 can be integrally formed with the outdoor fan 14, or it can be separately formed from the outdoor fan 14 and then connected. During installation, the water spraying component 13 can be first assembled with the outdoor fan 14 to form a whole before being assembled with the motor.

[0050] For example, the water-discharging component 13 is annular. The water-discharging component 13 can be connected to the blades of the outdoor fan 14 without the need for additional drive components. For example, the water-discharging component 13 is located on the side of the guide ring 111 away from the indoor unit 20 to increase the distance between the water-discharging component 13 and the indoor unit 20, thereby reducing the probability of condensate water agitated by the water-discharging component 13 entering the indoor unit 20.

[0051] Please see Figure 1 , Figure 3 and Figure 4 The first water guide 112 protrudes from the air inlet side of the guide ring 111, and the first water guide 112 has a first flow channel 112a, at least a portion of which is located on the rotation path of the outdoor fan 14.

[0052] The second water guide 113 is connected to the flow guide ring 111 and to the periphery of the first water guide 112. The second water guide 113 has a second flow channel 113a. One end of the second flow channel 113a is connected to the first flow channel 112a along the axial direction, and the other end is connected to the airflow channel 111a, so as to guide the liquid agitated by the outdoor fan 14 through the first flow channel 112a to the water agitator 13.

[0053] In other words, the first water guide 112 protrudes from the front side of the guide ring 111, that is, the end closer to the indoor side.

[0054] The first flow channel 112a is a channel for liquid flow defined by the shape of the first water guide 112. At least a portion of the first flow channel 112a is located on the rotation path of the outdoor fan 14, that is, at least a portion of the first flow channel 112a is on the rotation trajectory of the outdoor fan 14. During the rotation of the outdoor fan 14, the outdoor fan 14 will come into contact with the first water guide 112, so that the water agitated by the outdoor fan 14 can be contained within the first flow channel 112a without splashing outwards.

[0055] The second water guide 113 protrudes from the front side of the guide ring 111. The second water guide 113 is connected and fitted with the first water guide 112 along the circumferential direction of the guide ring 111, and the second water guide 113 is located downstream of the first water guide 112 along the fluid flow direction.

[0056] The second flow channel 113a is a channel for liquid flow defined by the shape of the second water guide 113. One end of the second flow channel 113a is connected to the first flow channel 112a along the axial direction, and the other end is connected to the second flow channel 113a along the axial direction. That is, the water agitated by the outdoor fan 14 flows along the rotation path in the first flow channel 112a and can flow to the second flow channel 113a under the action of the wind. Under the action of the second flow channel 113a, it flows back to the airflow channel 111a along the axial direction. For example, it flows to the inner wall surface of the guide ring 111 and is received by the water agitator 13. The water agitator 13 then pushes the condensate to the outdoor heat exchanger 12 to achieve heat exchange.

[0057] It is understandable that the water-discharging component is a closed ring, and the condensate water it discharging has a small diffusion range and is not easy to splash. However, the outdoor fan discharging condensate water relies on the fan blades. In related technologies, some of the condensate water discharging by the water-discharging component is received by the outdoor fan, or when the condensate water accumulation is high, the outdoor fan directly discharging the condensate water. The condensate water will splash under the action of the outdoor fan, which is not conducive to the heat exchange efficiency of the outdoor heat exchanger and is prone to creating safety hazards.

[0058] The outdoor enclosure 11 provided in this embodiment has a first flow channel 112a adapted to the rotation path of the outdoor fan 14, which guides the condensate water stirred up by the outdoor fan 14, reducing the probability of the water stirred up by the outdoor fan 14 splashing outwards. At the same time, under the action of the wind force of the outdoor fan 14, the condensate water stirred up by the outdoor fan 14 flows through the first flow channel 112a to the second flow channel 113a, and flows back to the water spraying component 13 axially from the second flow channel 113a. In this way, the water stirred up by the outdoor fan 14 will not splash outwards, and can return to the guide ring 111 to be used by the water spraying component 13 and sprayed towards the outdoor heat exchanger 12, reducing the probability of condensate water waste and increasing the heat exchange performance of the outdoor heat exchanger 12. Of course, the size of the first water guide 112 and the second water guide 113 can also be small. The first water guide 112 and the second water guide 113 can be set only in the bottom area of ​​the guide ring 111. When the outdoor fan 14 starts to generate condensate, it receives the condensate and guides it to the guide ring 111, reducing the impact on the efficiency of the air duct.

[0059] The size of the first water guide 112 only needs to be adapted to the blade of one of the outdoor fans 14, without forming an integral structure that wraps around the blade, thus reducing the impact on the duct efficiency of the guide ring 111.

[0060] In some embodiments, please refer to Figure 3 and Figure 4 The first flow channel 112a extends circumferentially along the guide ring 111.

[0061] In other words, the first flow channel 112a can be formed as an annular groove extending circumferentially along the guide ring 111. The entire first flow channel 112a is located on the rotation path of the outdoor fan 14. When the outdoor fan 14 rotates, each fan blade will pass through the first flow channel 112a to cut into the first flow channel 112a, and the condensate water that is stirred up will flow along the first flow channel 112a to the second flow channel 113a.

[0062] In this embodiment, the first flow channel 112a extends circumferentially along the guide ring 111, so that the condensate water generated by the outdoor fan 14 falls into the first flow channel 112a, and at the same time, flows stably along the first flow channel 112a to the second flow channel 113a.

[0063] In some embodiments, please refer to Figure 3 and Figure 4 The second flow channel 113a extends along the axial direction of the guide ring 111.

[0064] In this embodiment, the second flow channel 113a is formed as a channel extending axially along the guide ring 111. Thus, one end of the second flow channel 113a along the axial direction receives condensate from the first flow channel 112a. Then, under the action of the wind force of the outdoor fan 14, the condensate flows axially towards the air inlet side of the guide ring 111, is received by the water spraying component 13, and sprays towards the outdoor heat exchanger 12. The structure is simple.

[0065] In some embodiments, please refer to Figure 3 and Figure 4 Along the radial direction close to the center of the guide ring 111, no part of the second water guide 113 extends beyond the inner wall surface of the guide ring 111.

[0066] It is understandable that the inner wall of the guide ring 111 forms an airflow channel 111a. The center of the guide ring 111 is the geometric center of the airflow channel 111a.

[0067] In this embodiment, in the radial direction close to the center of the guide ring 111, the highest surface of the second water guide 113 will not exceed the plane where the guide ring 111 is located. No part of the second water guide 113 will block the guide ring 111. Thus, the second water guide 113 can guide the condensate back to the water pump 13 without blocking the airflow channel 111a. That is, it does not affect the gap between the guide ring 111 and the blades of the outdoor fan 14. The second water guide 113 does not affect the air intake of the outdoor fan 14, reducing the impact on the efficiency of the air duct.

[0068] In some embodiments, the second water guide 113 has a first end face 113b and a second end face 113c in the circumferential direction, and a second flow channel 113a is defined between the first end face 113b and the second end face 113c. The first end face 113b is connected to the first water guide 112.

[0069] The first end face 113b is the side end face of the second water guide 113 that is close to the first water guide 112 along the circumferential direction, and the second end face 113c is the side end face of the second water guide 113 that is far away from the first water guide 112 along the circumferential direction. The first end face 113b and the second end face 113c are spaced apart along the circumferential direction, and the space between them defines the second flow channel 113a.

[0070] Please see Figures 3 to 4 Along the radial direction close to the center of the guide ring 111, the first end face 113b and the second end face 113c are the highest surfaces of the second water guide 113.

[0071] In other words, in the radial direction toward the center of the guide ring 111, the first end face 113b and the second end face 113c are the parts of the second water guide 113 closest to the center of the guide ring 111. The parts of the second water guide 113 other than the first end face 113b and the second end face 113c are lower than the first end face 113b and the second end face 113c. Thus, in the radial direction toward the center of the guide ring 111, the second water guide 113 can be roughly formed into a structure that is high at both ends and low in the middle. In this way, the condensate water agitated by the outdoor fan 14 flows circumferentially in the first flow channel 112a, and can change direction in the second flow channel 113a, flowing back to the guide ring 111 axially.

[0072] In some embodiments, please refer to Figure 3 and Figure 4 The position of the first end face 113b is flush with the inner wall surface of the guide ring 111.

[0073] In this embodiment, the first end face 113b will not protrude or be recessed radially relative to the inner wall surface of the guide ring 111. The first end face 113b can smoothly transition with the inner wall surface of the guide ring 111. This facilitates the reception of condensate from the first flow channel 112a and facilitates the return of condensate to the guide ring 111, reducing resistance and increasing the smoothness of condensate flow. Of course, it will not affect the air intake efficiency of the guide ring 111.

[0074] In some embodiments, please refer to Figure 3 and Figure 4 The position of the second end face 113c is flush with the inner wall surface of the guide ring 111.

[0075] In this embodiment, the second end face 113c will not protrude or be recessed radially relative to the inner wall surface of the guide ring 111. The second end face 113c can smoothly transition with the inner wall surface of the guide ring 111. This facilitates the reception of condensate from the first flow channel 112a and facilitates the return of condensate to the guide ring 111, reducing resistance and increasing the smoothness of condensate flow. Of course, it will not affect the air intake efficiency of the guide ring 111.

[0076] In some embodiments, please refer to Figure 3 and Figure 4 The end face of the second water guide 113 that is axially away from the guide ring 111 does not extend beyond the end face of the first water guide 112 that is axially away from the guide ring 111.

[0077] For example, the side end face of the second water guide 113 away from the guide ring 111 along the axial direction is flush with the side end face of the first water guide 112 away from the guide ring 111 along the axial direction.

[0078] In this embodiment, along the direction from the air outlet side to the air inlet side of the guide ring 111, the end face of the second water guide 113 will not exceed the end face of the first water guide 112. The second flow channel 113a can be located within the wind force range of the outdoor fan 14, which facilitates the second water guide 113 receiving the condensate from the first flow channel 112a and flowing it towards the air inlet side of the guide ring 111 under the action of the wind force, guiding the condensate back to the guide ring 111, reducing the probability of condensate dripping to the outside through the second flow channel 113a, and increasing the reliability of water guiding.

[0079] In some embodiments, the sum of the circumferential dimensions of the first water guide 112 and the second water guide 113 does not exceed 1 / 4 of the circumferential dimension of the flow guide ring 111. For example, the sum of the circumferential dimensions of the first water guide 112 and the second water guide 113 is 1 / 4, 1 / 5, 1 / 6, 1 / 7, 1 / 8, 1 / 9, 1 / 10, etc., of the circumferential dimension of the flow guide ring 111.

[0080] In this embodiment, the first water guide 112 and the second water guide 113 have small circumferential dimensions in the guide ring 111. On the one hand, it is not necessary to form an integral wrapping of the outdoor fan 14, which reduces the impact on the air intake efficiency of the outdoor fan 14. On the other hand, the first water guide 112 and the second water guide 113 occupy little space, which can also reduce production costs.

[0081] In some embodiments, please refer to Figure 3 and Figure 4 The first water guide 112 and the second water guide 113 are arranged along the height direction of the outdoor enclosure 11. That is, the first water guide 112 and the second water guide 113 have no overlap in the height direction. The first water guide 112 is located below the second water guide 113. When the outdoor fan 14 pumps condensate from below, it flows upward along the first water guide 112 to the second water guide 113. The second water guide 113 guides the condensate back to the guide ring 111 along the axis. In this way, the first water guide 112 is located in the bottom area of ​​the outdoor enclosure 11, which facilitates the rapid collection of condensate when the outdoor fan 14 pumps condensate, further reducing the chance of splashing.

[0082] The specific structure of the first water guide component 112 is not limited.

[0083] In some embodiments, please refer to Figure 4 The first water guide 112 includes a connecting plate 1121 and a baffle plate 1122. The second water guide 113 is connected to the periphery of the connecting plate 1121. One end of the connecting plate 1121 along the axial direction is connected to the flow guide ring 111, and the other end is connected to the baffle plate 1122. The baffle plate 1122 extends from the connection point with the connecting plate 1121 toward the direction close to the flow guide ring 111. The space between the baffle plate 1122 and the connecting plate 1121 defines the first flow channel 112a.

[0084] When the outdoor fan 14 rotates, the blades of the outdoor fan 14 can contact the baffle plate 1122, and the baffle plate 1122 can catch the condensate water stirred up by the outdoor fan 14 and keep it in the first flow channel 112a.

[0085] In this embodiment, the connecting plate 1121 connects the guide ring 111 and the baffle plate 1122 to reduce the impact on the outdoor fan 14. The baffle plate 1122 extends from the connection point with the connecting plate 1121 towards the guide ring 111, which can shield the condensate water and prevent the condensate water from splashing outward, thus achieving a good water blocking effect.

[0086] In some embodiments, the connecting plate 1121 and the inner wall surface of the guide ring 111 transition smoothly.

[0087] In this embodiment, the connecting plate 1121 will not protrude or be recessed relative to the guide ring 111, which can reduce the impact on the air intake efficiency of the outdoor fan 14. At the same time, it is also convenient to form a smooth structure for the flow of condensate water and smoothly connect with the second water guide 113, reducing flow resistance. Of course, it can also reduce manufacturing difficulty.

[0088] In some embodiments, the baffle plate 1122 is formed as an arc-shaped structure, with the arc-shaped opening facing the air inlet side of the guide ring 111.

[0089] This facilitates the adaptation of the structure of the blades of the outdoor fan 14, reduces the rotational resistance of the outdoor fan 14, increases the smoothness of the rotation of the outdoor fan 14, and at the same time reduces the flow resistance of condensate, making it easier for condensate to flow to the second water guide 113.

[0090] The specific structure of the second water guide 113 is not limited.

[0091] In some embodiments, please refer to Figure 4 The second water guide 113 includes a first plate 1131 and a second plate 1132. The first plate 1131 is connected to the first water guide 112 and the second plate 1132. One end of the first plate 1131 and the second plate 1132 along the axial direction is connected to the flow guide ring 111, and the other end of the first plate 1131 and the second plate 1132 along the axial direction extends away from the air inlet side of the flow guide ring 111. The space between the first plate 1131 and the second plate 1132 defines the second flow channel 113a. The first plate 1131 and the second plate 1132 are arranged at an angle.

[0092] Specifically, the first end face 113b is formed on the side end face of the first plate 1131 that is circumferentially away from the second plate 1132, and the second end face 113c is formed on the side end face of the second plate 1132 that is circumferentially away from the first plate 1131.

[0093] In this embodiment, the first plate 1131 and the second plate 1132 are arranged at an angle. On the one hand, this facilitates the avoidance of the outdoor fan 14 and guides the condensate to flow through the guide ring 111 under the action of the outdoor fan 14. On the other hand, it also facilitates the change of the flow direction of the condensate, reducing the probability of condensate splashing in the second flow channel 113a. At the same time, it facilitates the flow of condensate through the guide ring 111.

[0094] For example, please refer to Figure 3 and Figure 4 The plane of the first plate 1131 is perpendicular to the height direction of the outdoor enclosure 11, and the second plate 1132 is perpendicular to the first plate 1131. This makes it easier to change the flow direction of the condensate when the first plate 1131 receives the condensate from the first flow channel 112a, and to keep the condensate flowing approximately horizontally, further reducing the chance of splashing. At the same time, the condensate flows back to the guide ring 111 along the second plate 1132.

[0095] In some embodiments, please refer to Figure 3 The first plate 1131 extends from the connection point with the first water guide 112 in a direction away from the center of the guide ring 111, and the second plate 1132 extends from the connection point with the first plate 1131 in a direction closer to the center of the guide ring 111.

[0096] Thus, the condensate flows from the first water guide 112 to the first plate 1131, flows at the first plate 1131 in a direction away from the center of the guide ring 111 to the second plate 1132, and then extends at the second plate 1132 in a direction closer to the center of the guide ring 111 to flow back to the guide ring 111.

[0097] In this embodiment, the first plate 1131 can smoothly receive condensate while keeping it away from the outdoor fan 14. The second plate 1132 can guide the condensate back to the guide ring 111 under the wind force of the outdoor fan 14. Thus, the water guiding efficiency is high, and no additional auxiliary structure is required. Of course, the structure of the first plate 1131 and the second plate 1132 is relatively simple and easy to form.

[0098] For example, in some embodiments, the outdoor enclosure 11 is a one-piece structure, that is, the panel 110, the guide ring 111, the first water guide 112 and the second water guide 113 are integrally formed into the outdoor enclosure 11. In this way, the manufacturing difficulty is low and the assembly efficiency is high.
