[0035] As described in the background section, air conditioners, as an indispensable environmental control device in modern life, are widely used in various places such as homes, offices, and businesses. Since the heat exchanger in an air conditioner mainly achieves heat exchange through the flow of air, after the air conditioner has been running for a long time, the heat exchanger will absorb impurities such as dust, willow catkins, and pollen from the air.
[0036] To avoid impurities affecting the heat exchange efficiency of the heat exchanger, it is necessary to clean the heat exchanger regularly. However, the existing heat exchanger cleaning devices are relatively complex in structure and have a high failure rate. Some cleaning devices also need to occupy the space between the fan and the heat exchanger, thereby affecting airflow and resulting in low heat exchange efficiency.
[0037] To address the problems of complex structure and reduced heat exchange efficiency in existing heat exchanger cleaning devices, this application provides a cleaning device including a guide rail, a spray element, a water supply pipeline, and a drive assembly. The guide rail is positioned above the heat exchanger, and the spray element, equipped with spray holes, can move along the guide rail and spray water onto the heat exchanger. The spray area formed by the spray element along the guide rail is greater than or equal to the cross-sectional area of the heat exchanger.

The drive assembly includes multiple drive units, each including a drive motor, a roller, and a flexible rope. The motor's output end is connected to the roller, one end of the flexible rope is connected to the roller, and the other end of the flexible rope is connected to the spray element.
[0038] With the above technical solution, the cleaning device can be installed above the heat exchanger. The cleaning device has a simple structure and small size, which can make full use of the space between the heat exchanger and the air conditioner ceiling, avoid occupying the space of the fan and heat exchanger, and ensure the heat exchange efficiency of the heat exchanger.
[0039] The following reference Figures 1 to 5 The cleaning apparatus of this application is described. Among them, Figure 1 This is an overall structural diagram of the cleaning device of this application; Figure 2 This is a schematic diagram of the installation of the cleaning device and heat exchanger in this application; Figure 3 This is a schematic diagram showing the installation of the cleaning device and housing according to this application; Figure 4 This is a structural diagram of the spray component of this application; Figure 5This is a structural diagram of the driving component of this application.
[0040] like Figures 1 to 5 As shown, in a preferred embodiment, the cleaning device 2 includes a guide rail 21, a spray element 22, a water supply pipe 23, a drive assembly 24, a guide assembly 25, and a traction structure 26. The guide rail 21 is positioned above the heat exchanger 5, and both the guide rail 21 and the heat exchanger 5 are L-shaped, compatible with each other, and can be installed onto the top plate 61 of the air conditioner's casing 6. The spray element 22 can move along the guide rail 21 and has spray holes. The spray element 22 can spray water onto the heat exchanger 5, and the spray area formed by the spray element 22 along the guide rail 21 is greater than or equal to the cross-sectional area of the heat exchanger 5. Specifically, the spray element 22 is located above the guide rail 21, the spray holes are located at the bottom of the spray element 22, and the guide rail 21 allows water to flow through. One end of the water supply pipe 23 is used to connect to a water source, and the other end is connected to the sprinkler unit 22. The water supply pipe 23 is configured as a retractable pipe, and the water source includes one or more of condensate, rainwater, and tap water.
[0041] Three drive components 24 are configured. Each drive component 24 includes a drive motor 241, a roller 242, and a flexible rope 243. The three drive motors 241 are located at the first end, the inflection point, and the second end of the guide rail 21, respectively, and all three drive motors 241 are connected to the top plate 61. The three rollers 242 are connected to the output ends of the corresponding drive motors 241, and the two ends of the three flexible ropes 243 are connected to the corresponding rollers 242 and the spray element 22, respectively. Specifically, a traction structure 26 is provided on the top of the spray element 22, and the flexible ropes 243 are connected to the traction structure 26. The guide component 25 is used to guide the spray element 22 as it moves along the guide rail 21. Specifically, the guide component 25 includes two rollers, which are located on both sides of the spray element 22 and are in rolling connection with the guide rail 21.
[0042] In this embodiment, the reciprocating movement of the spray element 22 on the guide rail 21 is achieved by three drive components 24. Specifically, for each drive component 24, the drive motor 241 drives the roller 242 to rotate, and one end of the flexible rope 243 is connected to the roller 242. Therefore, the flexible rope 243 can be wound around the roller 242. The forward or reverse rotation of the drive motor 241 can cause the roller 242 to rotate in both directions, and the forward or reverse rotation of the roller 242 can achieve the contraction and extension of the flexible rope 243. Figure 1Taking the direction shown as an example, the drive component 24 located at the first end of the guide rail 21, i.e., the lower left corner, is the first drive component 24; the drive component 24 located at the inflection point of the guide rail 21 is the second drive component 24; and the drive component 24 located at the second end of the guide rail 21, i.e., the upper right corner, is the third drive component 24. When the spray component 22 moves from the first end of the guide rail 21 to the inflection point, the flexible rope 243 in the first drive component 24 extends, and the flexible rope 243 in the second and third drive components 24 contracts. When the spray component 22 moves from the inflection point of the guide rail 21 to the second end, the flexible rope 243 in the first and second drive components 24 extends, and the flexible rope 243 in the first drive component 24 contracts. Similarly, the motion law of the spray component 22 when it moves from the second end to the first end of the guide rail 21 can be obtained, which will not be elaborated here. During the movement, the water supply pipe 23 extends or retracts with the movement of the spray element 22 and continuously supplies water to the spray element 22. The spray element 22 can spray water from the top of the heat exchanger 5 to the heat exchanger 5, thereby cleaning the heat exchanger 5. The cleaned water is discharged from the drain port 621 on the base plate 62.
[0043] It should be explained that although the water supply pipe 23 is set as a retractable pipe in this embodiment, its setting is not mandatory. In an alternative embodiment, the water supply pipe 23 can be set as a regular pipe of a certain length. In this case, a storage structure can be provided. The water supply pipe 23 can leave or enter the storage structure by cooperating with the movement of the spray element 22, thereby avoiding affecting the movement of the spray element 22. In addition, although both the guide rail 21 and the heat exchanger 5 are set as L-shaped in this embodiment, their setting is not fixed. In an alternative embodiment, both the guide rail 21 and the heat exchanger 5 can be set as straight or U-shaped. In this case, the number of drive components 24 can also be changed according to the needs of those skilled in the art. For example, when both the guide rail 21 and the heat exchanger 5 are set as straight, only one drive component 24 can be set at each end of the guide rail 21. As another example, when both the guide rail 21 and the heat exchanger 5 are set as U-shaped, only four drive components 24 can be set at the two ends and two bends of the guide rail 21. Of course, when both the guide rail 21 and the heat exchanger 5 are set to L-shape, the number of drive components 24 can also be changed according to the needs of those skilled in the art. For example, only one drive component 24 can be set at each end of the guide rail 21.
[0044] It should also be explained that in this embodiment, the spray element 22 is located above the guide rail 21, but the relative position of the spray element 22 and the guide rail 21 is not fixed. In an alternative embodiment, the spray element 22 can be located below the guide rail 21, that is, the spray element 22 can be hung on the guide rail 21, and the normal function of the spray element 22 and the guide rail 21 can still be achieved. In addition, in this embodiment, the spray element 22 can move on the guide rail 21 through the guide components 25 on both sides, i.e., rollers, but their arrangement is not fixed. In an alternative embodiment, the arrangement of the guide components 25 can be omitted. In another alternative embodiment, those skilled in the art can modify it according to requirements and factors such as the shape of the guide rail 21, for example, by using a gear rack, a slider rail, etc. for guidance. Furthermore, in this embodiment, only one traction structure 26 is provided on the top of the spray component 22, and all three flexible ropes 243 are connected to the traction structure 26. However, its provision is not mandatory. In an alternative embodiment, those skilled in the art can change the number and location of the traction structure 26 as needed, as long as it does not hinder the normal functioning of the flexible ropes 243.
[0045] This application also provides an air conditioner that includes any of the cleaning devices 2 described above.
[0046] The following is combined with Figure 2 and Figure 3 The air conditioner of this application is described below. In one possible embodiment, the air conditioner includes a housing 6, which includes a top plate 61 and a bottom plate 62. The bottom plate 62 is provided with a drain outlet 621. A guide rail 21 is connected to the top plate 61, and a plurality of drive motors 241 are connected to the top plate 61.
[0047] In this embodiment, the air conditioner includes an outdoor unit and an indoor unit. Figure 2 and Figure 3 The outdoor unit of the air conditioner has a heat exchanger 5 that is a condenser. A cleaning device 2 is positioned above the condenser and connected to the top plate 61 of the casing 6. A drain outlet 621 is provided on the bottom plate 62 of the casing 6. After cleaning, the water can be discharged directly to the outside through the drain outlet 621 or through a drain pipe connected to the drain outlet 621. It should be noted that although this embodiment uses a condenser as an example for the heat exchanger 5, the cleaning device 2 can also be applied to the evaporator in the indoor unit of the air conditioner, as long as it does not affect the normal functioning of the cleaning device 2 and other components of the air conditioner.

Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
