[0016] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will clearly and completely describe the technical solutions in the present utility model in conjunction with the drawings in the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0017] Refer to the attached Figure 1, this embodiment provides an automatic cleaning device for an air conditioner outdoor unit, including a first water tank 1 and a second water tank 2. The lower end of the first water tank 1 is connected to the second water tank 2 through a one-way valve 3. The water in the first water tank 1 cannot flow into the second water tank 2 through the one-way valve 3, while the water in the second water tank 2 can flow into the first water tank 1 through the one-way valve 3. The upper end of the first water tank 1 is connected to the second water tank 2 through a water guiding pipe 4. A liquid level sensor is provided at the lower end of the second water tank 2, and a water inlet pipe 5 is provided at the upper end of the first water tank 1. Water is added into the first water tank 1 through the water inlet pipe 5. After the first water tank 1 is filled, the second water tank 2 is filled through the water guiding pipe 4. Outlet pipes 6 are provided at the bottoms of both the first water tank 1 and the second water tank 2. The two outlet pipes 6 are connected to a cleaning water pipe 8 through a reversing valve 7. A spray head 9 is connected to the cleaning water pipe 8, and a booster pump 10 is provided on the cleaning water pipe 8 between the spray head 9 and the reversing valve 7. The spray heads 9 are distributed above the condenser of the outdoor unit 11. The cleaning water pipe 8 is connected to the second water tank 2 through the reversing valve 7. When the booster pump 10 is started, the water in the second water tank 2 enters the cleaning water pipe 8, and the spray heads 9 conduct a preliminary cleaning of the condenser of the outdoor unit 11. When the water in the second water tank 2 is almost used up, the liquid level sensor sends a signal to control the booster pump 10 to stop working to avoid the booster pump 10 running idly. This cleaning can remove most of the dirt on the condenser of the outdoor unit 11, wet the difficult-to-clean dirt and soften it. After a predetermined time, the cleaning water pipe 8 is connected to the first water tank 1 through the reversing valve 7. The booster pump 10 is started, the water in the second water tank 2 enters the cleaning water pipe 8, and the water in the first water tank 1 enters the second water tank 2. The spray heads 9 conduct a re-cleaning of the condenser of the outdoor unit 11. When the water in the second water tank 2 is almost used up, the liquid level sensor sends a signal to control the booster pump 10 to stop working. During the re-cleaning, since the difficult-to-clean dirt is softened after being wetted during the preliminary cleaning, and at the same time, the water in both the first water tank 1 and the second water tank 2 is used for cleaning, the cleaning water volume is increased. The cooperation of the two ensures the cleaning effect of the condenser of the outdoor unit 11. Between the preliminary cleaning and the re-cleaning, the second water tank 2 is replenished with water through the water inlet pipe 5 and the water guiding pipe 4.

[0018] As another embodiment of the present utility model: An overflow pipe 12 is provided at the upper end of the first water tank 1, and the horizontal position of the overflow pipe 12 is higher than that of the water guiding pipe 4. When the water in the first water tank 1 is excessive, it will flow out from the overflow pipe 12.

[0019] As another embodiment of the present utility model: A three-way joint 13 is connected to the water inlet pipe 5. The other two joints of the three-way joint 13 are respectively connected to a first water pipe 14 and a second water pipe 15. The first water pipe 14 is used to connect a condensate water outlet pipe (not shown), and this setting can recycle the condensate water generated by the indoor unit and reduce the waste of condensate water. The second water pipe 15 is used to connect to a water source. Specifically, the second water pipe 15 can be connected to a tap water pipe to replenish water to the first water tank 1 when the condensate water is insufficient.

[0020] As another embodiment of the present utility model: The second water pipe 15 is also used to connect a cleaning agent, and the cleaning agent is added to the first water tank 1 and the second water tank 2 through the second water pipe 15, which can effectively improve the cleaning effect of the nozzle 9; or the second water pipe 15 is connected to a third water pipe and a fourth water pipe through a tee joint 13, the third water pipe is used to connect to a water source, and the fourth water pipe is used to connect to a cleaning agent.

[0021] Specifically, the first water tank 1 and the second water tank 2 are arranged side by side.

[0022] As another embodiment of the present utility model: The nozzles 9 are also distributed on the sides of the condenser of the outdoor unit 11.

[0023] Specifically, the water inlet pipe 5 is connected to the top of the first water tank 1, and the reversing valve 7 is an electromagnetic reversing valve.

[0024] Finally, it should be noted that: The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
