[0021] In order to make the objectives, technical solutions, and advantages of this application clearer, the following further elaborates on this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely used to explain this application and are not intended to limit this application.

[0022] Please refer to Figure 1 and Figure 2 , which shows an outdoor unit 100 provided by an embodiment of this application. The outdoor unit 100 is a device installed outdoors in a household or commercial air-conditioning system and is an important part of the air-conditioning system. The outdoor unit 100 mainly includes a compressor, a fan, a refrigerant, electrical components, etc. The main function of the outdoor unit 100 is to discharge the indoor heat outdoors through the circulation of the refrigerant and at the same time release cold air into the room, thereby achieving the control of the room temperature and humidity.

[0023] During the operation of the outdoor unit 100, condensate may accumulate inside it. To effectively manage this condensate, some outdoor units 100 integrate a water pump 2 inside. The main function of the water pump 2 is to improve the discharge efficiency of the condensate, enabling the condensate to be discharged quickly and smoothly, thereby preventing the adverse impact of water accumulation on the normal operation of the air-conditioning system.

[0024] Specifically, the outdoor unit 100 can include a housing 1. The housing 1 is generally made of aluminum alloy sheet by stamping and sheet metal working. As the main component of the outdoor unit 100, the housing 1 provides a stable installation platform for each component of the outdoor unit 100, ensuring that they can maintain the correct relative positions during operation and avoiding displacement or damage due to vibration or external forces.

[0025] An accommodation cavity can be formed inside the housing 1, which can be used to install a compressor, a fan, a water pump 2, etc. An inspection opening 101 can be provided on the outer side of the housing 1. The inspection opening 101 can communicate with the accommodation cavity, and the inspection opening 101 can be arranged opposite to the water pump 2, while the water pump 2 can extend out of the housing 1 from the inspection opening 101, so that at least part of the water pump 2 is located outside the housing 1.

[0026] Thus, when the outdoor unit 100 malfunctions, it is possible to directly observe from the outside of the housing 1 whether the fault light on the water pump 2 is on, which is convenient for maintenance personnel to troubleshoot the cause of the malfunction of the outdoor unit 100. If it is determined that the water pump 2 has malfunctioned, when repairing the water pump 2, it is possible to directly repair the water pump 2 outside the housing 1, which is very convenient for repairing the water pump 2. Moreover, even when it is necessary to disassemble the water pump 2, there is no need to disassemble the side plate 14 of the housing 1, and the water pump 2 can be directly disassembled from the housing 1 through the maintenance opening 101, which is very convenient for repairing the water pump 2. And after the water pump 2 extends out of the housing 1, the space occupied by the water pump 2 in the accommodation cavity can also be reduced, so that the accommodation cavity can have a larger space for installing other components such as a compressor and a fan.

[0027] Please refer to Figure 1 , in some embodiments, the outdoor unit 100 may further include a cover 3, the cover 3 can be disposed outside the housing 1, and the cover 3 can also open or close the maintenance opening 101. When the cover 3 closes the maintenance opening 101, the cover 3 and the housing 1 can enclose to form an accommodation cavity, and the part of the water pump 2 extending out of the housing 1 from the maintenance opening 101 can be located in the accommodation cavity.

[0028] Optionally, the cover 3 has an opening, the contour shape of the opening is the same as the contour shape of the maintenance opening 101, and the contour size of the opening is larger than the contour size of the maintenance opening 101. When the cover 3 closes the maintenance opening 101, the cover 3 can cover the maintenance opening 101, and a part of the water pump 2 extends into the accommodation cavity formed by the cover 3.

[0029] Specifically, when the outdoor unit 100 is operating normally, the cover 3 can close the maintenance opening 101, so that the cover 3 can prevent dust from entering the interior of the housing 1 through the maintenance opening 101, thereby preventing damage to the components inside the housing 1. When the water pump 2 malfunctions, the cover 3 is removed from the maintenance opening 101, so that the maintenance opening 101 can be opened, and the water pump 2 is exposed from the maintenance opening 101, which is convenient for the maintenance personnel to repair the water pump 2.

[0030] Please refer to Figure 1 , in some embodiments, the cover 3 may include a cover body 31 and a flange plate 32 connected to the cover body 31.

[0031] Optionally, the inner wall surface of the cover 31 can define a receiving cavity, and the cover 31 has an opening communicating with the receiving cavity. The overlapping edge plate 32 can be arranged to extend along the circumferential direction of the cover 31, that is to say, the overlapping edge plate 32 extends along the circumferential side wall defining the opening. The overlapping edge plate 32 is also arranged at an angle with the side wall of the cover 31. Preferably, the angle between the overlapping edge plate 32 and the side wall of the cover 31 is an obtuse angle or a right angle. Thus, when the cover 31 covers the maintenance opening 101, the overlapping edge plate 32 can overlap with the wall surface of the maintenance opening 101 defined by the housing 1, and the overlapping edge plate 32 and the housing 1 can be connected through a connecting structure, so that the cover 31 can close the maintenance opening 101.

[0032] Optionally, the cover 31 can be provided with reinforcing ribs. As an additional support structure, the reinforcing ribs can increase the overall strength and stiffness of the cover, and prevent deformation or damage caused by external forces (such as wind pressure, collision, etc.). And the reinforcing ribs can be arranged at the folding corners of the cover, which can increase the structural strength of the stress points such as the folding corners, and can significantly improve the stability of the cover.

[0033] Please refer to Figure 1 and Figure 2 , in some embodiments, at least one of the cover 3 and the housing 1 can be provided with a buckle 4, and at least the other of the cover 3 and the housing 1 can be provided with a slot 5. The buckle 4 can be engaged with the slot 5 in a snap-fit manner, so that the cover 3 can be detachably connected to the housing 1. By providing the buckle 4 and the slot 5, the cover 3 and the housing 1 can be easily connected together, and then the maintenance opening 101 can be easily opened or closed.

[0034] Optionally, a plurality of buckles 4 are provided on the cover 3. The plurality of buckles 4 can be arranged at intervals along the circumferential direction of the cover 3. The housing 1 can be provided with a plurality of slots 5. The plurality of slots 5 can be arranged at intervals along the circumferential direction of the maintenance opening 101. And the plurality of buckles 4 can correspond to the plurality of slots 5 one by one, so that each buckle 4 can be engaged with the corresponding slot 5, thereby connecting the cover 3 to the housing 1. When the water pump 2 needs to be maintained, it is only necessary to disengage the buckle 4 from the slot 5.

[0035] In some other embodiments, it can be that the cover 3 is provided with a plurality of slots 5. The plurality of slots 5 are arranged at intervals along the circumferential direction of the cover 3. The housing 1 can be provided with a plurality of buckles 4. The plurality of buckles 4 can be arranged at intervals along the circumferential direction of the maintenance opening 101. Similarly, the plurality of buckles 4 can be arranged to correspond to the plurality of slots 5 one by one.

[0036] Of course, the cover 3 can be provided with a plurality of buckles 4 and a plurality of slots 5 at the same time, and the housing 1 can also be provided with a plurality of buckles 4 and a plurality of slots 5 at the same time. For the convenience of description, the buckles 4 and slots 5 on the cover 3 are defined as the first buckles 4 and the first slots 5, and the buckles 4 and slots 5 on the housing 1 are defined as the second buckles 4 and the second slots 5.

[0037] Specifically, a plurality of first clips 4 and a plurality of first slots 5 can be arranged in sequence at intervals along the circumference of the cover shell 3, while a plurality of second clips 4 and a plurality of second slots 5 can be arranged in sequence at intervals along the circumference of the inspection port 101, and a plurality of first clips 4 can be arranged in one-to-one correspondence with a plurality of second slots 5, and a plurality of first slots 5 can be arranged in one-to-one correspondence with a plurality of second clips 4, so that the first clips 4 can be engaged with the corresponding second slots 5, and the second clips 4 can be engaged with the corresponding first slots 5.

[0038] Optionally, a plurality of buckles 4 can be provided on the lap plate 32 , and the buckles 4 are located on the side of the lap plate 32 away from the cover body 31 , so that the plurality of buckles 4 can be arranged toward the shell 1 , facilitating the buckle 4 to be engaged with the slot 5 on the shell 1 .

[0039] Optionally, the lap board 32 can be formed into a circle, a square or a polygon. When the lap board 32 is formed into a square or a polygon, at least two of the multiple clips 4 can be respectively arranged on different sides of the lap board 32 to prevent the multiple clips 4 from being concentrated on the same side of the lap board 32. When the lap board 32 is connected to the shell 1, the connection points between the lap board 32 and the shell 1 can be dispersed, so that the force is more uniform, so that the lap board 32 and the shell 1 can be connected more stably.

[0040] When the side plate 32 is formed into a circle, the circle formed by the side plate 32 is divided into four arc segments, the arc lengths of the four arc segments are equal, at least two of the multiple buckles 4 can be respectively arranged on two arc segments, and the two arc segments are not arranged adjacent to each other. Similarly, the side plate 32 and the housing 1 can be connected more stably.

[0041] In some embodiments, the outdoor unit 100 can further include a connector, which can be used to connect the housing 1 and the cover 3 , and the connector is opposite to and spaced from at least one buckle 4 .

[0042] Optionally, after the cover shell 3 and the shell 1 are snapped together by the buckle 4 and the slot 5, the cover shell 3 and the shell 1 can also be connected together by a connecting piece, so that the cover shell 3 and the shell 1 can be connected more firmly, and the connecting piece can be opposite to and spaced apart from at least one buckle 4, so that the connecting piece and the buckle 4 can respectively fix different positions of the cover shell 3 to the shell 1. It can also be said that the connecting piece forms a first connection point between the cover shell 3 and the shell 1, the buckle 4 and the slot 5 form a second connection point between the cover shell 3 and the shell 1, and the first connecting piece and the second connecting piece are opposite to and spaced apart from each other, so that the shell and the shell 1 can be connected more stably.

[0043] Optionally, the connecting member can be a bolt. The housing 3 can be provided with a through hole, and the connecting member can pass through the through hole and be connected to the housing 1. More specifically, the housing 1 can be provided with a threaded hole. After the connecting member passes through the through hole, it can be threadedly connected to the threaded hole, so that the connecting member can fix the housing 3 to the housing 1. Threaded connection can also easily detach the housing 3 from the housing 1, facilitating the opening of the maintenance opening 101 for maintenance personnel to repair the water pump 2.

[0044] Please refer to Figure 1 , in some embodiments, there can be a gap between the water pump 2 and the wall surface defining the maintenance opening 101, that is to say, there can be a gap between the outermost side of the water pump 2 and the maintenance opening 101, so as to provide sufficient space for repairing the water pump 2, and during the process of repairing the water pump 2, it can also prevent the water pump 2 from colliding with the housing 1.

[0045] Please refer to Figure 1 and Figure 2 , in some embodiments, the housing 1 can include a top plate 11, a front plate 12, a rear plate 13, side plates 14, and a bottom plate 15.

[0046] Optionally, the two side plates 14 are arranged on opposite sides of the front plate 12. The front plate 12 is connected to the two side plates 14. The rear plate 13 is disposed opposite to the front plate 12 and is connected to the two side plates 14. The top plate 11 is arranged on the top of the front plate 12 and is connected to the front plate 12, the rear plate 13, and the two side plates 14. The bottom plate 15 is arranged at the bottom of the front plate 12 and is connected to the front plate 12, the rear plate 13, and the two side plates 14. Thus, the top plate 11, the front plate 12, the rear plate 13, the side plates 14, and the bottom plate 15 are assembled together to form the housing 1 of the outdoor unit 100. The side plate 14 can be provided with a maintenance opening 101, and the maintenance opening 101 being located on the side plate 14 can facilitate the water pump 2 to extend out from the maintenance opening 101.

[0047] It should be noted that in high-rise buildings, the outdoor unit 100 of the air conditioner is generally installed on the outer wall of the house, and the installation position for the outdoor unit 100 is very limited. Usually, the rear plate 13 of the outdoor unit 100 is arranged opposite to the outer wall, the front plate 12 of the outdoor unit 100 is arranged with its back facing the outer wall, and setting the maintenance opening 101 on the side plate 14 of the outdoor unit 100 can facilitate maintenance personnel to repair the water pump 2.

[0048] Specifically, when the front panel 12 is arranged with its back to the exterior wall, if the inspection opening 101 is arranged on the front panel 12, the maintenance personnel may need to go around the front of the outdoor unit 100 to reach the inspection opening 101. The inspection opening 101 on the side panel 14 may be more direct, reducing the obstacles of detour. Especially in some compact installation environments, there may be no remaining space in front of the front panel 12 for the water pump 2 to extend outward from the front panel 12, and often the space on the side of the side panel 14 is sufficient for the water pump 2 to extend out.

[0049] The position beside the side panel 14 may be more spacious than the front panel 12, so that maintenance personnel can squat to repair the water pump 2, so that the inspection port 101 on the side panel 14 may provide maintenance personnel with a more spacious operating space. When repairing the water pump 2 and other components, the more spacious space is conducive to maintenance personnel to carry out work better and improve the maintenance efficiency. In addition, setting the inspection port 101 on the side panel 14 can sometimes reduce the risk of maintenance personnel when performing high-altitude operations. Because the side panel 14 may be closer to the supporting structure or safety facilities of the building, it provides better support and protection for maintenance personnel.

[0050] Optionally, the front panel 12 usually directly faces the external environment and may be more susceptible to natural factors such as direct sunlight, rain, etc. The side panels 14 may be located in a more sheltered position, reducing the possibility of the inspection opening 101 being disturbed by the external environment, thereby protecting the integrity of the inspection opening 101 and its internal components.

[0051] The embodiment of the present application also provides an air conditioning system, which includes an indoor unit and an outdoor unit 100. The indoor unit is connected to the outdoor unit 100 through a pipeline to achieve circulation and regulation of cold and hot air.

[0052] Optionally, the indoor unit is usually installed inside the room, usually near the wall or ceiling, so as to better disperse the hot and cold air and reduce the impact on the indoor space. The main function of the indoor unit is to send the processed air (cooling or heating) into the room to maintain the set indoor temperature. It usually includes one or more fans, evaporators (when cooling) or heaters (when heating), air filters and other components. The outdoor unit 100 is installed outside the house, usually on a balcony, roof or a special equipment platform, and the outdoor unit 100 is responsible for discharging the indoor heat (when cooling) or cold (when heating) to the outside through the refrigerant cycle to keep the indoor temperature constant. The housing 1 of the outdoor unit 100 can be provided with an inspection port 101, and the water pump 2 inside the housing 1 can be extended from the inspection port 101, which can facilitate the inspection of the water pump 2.

[0053] See also Figure 1, in some embodiments, an access opening 101 is provided in the lower half of the side plate 14. From a structural design perspective, the water pump 2 is usually disposed in the lower half of the outdoor unit 100. The access opening 101 is disposed opposite to the water pump 2. Setting the access opening 101 in the lower half of the side plate 14 may better conform to the overall layout and weight distribution of the outdoor unit 100, which helps to ensure the stability and safety of the outdoor unit 100 and reduce potential problems caused by imbalance or weight concentration.
