[0058] The present embodiment also provides an air-conditioning outdoor unit, including the cleaning device of the air-conditioning outdoor heat exchanger in any of the above embodiments, and also including an air-conditioning outdoor heat exchanger and an outdoor unit fan 2. The cleaning device of the air-conditioning outdoor heat exchanger is connected to the outdoor unit fan 2 and is arranged toward the air-conditioning outdoor heat exchanger, and is used to spray water onto the air-conditioning outdoor heat exchanger.

[0059] The cleaning device of the outdoor heat exchanger of the air conditioner in this embodiment includes a water tank and a water spray assembly. The water tank is connected to the rotating shaft of the outdoor unit fan through an electromagnetic clutch, and the water spray assembly is arranged in the direction of the outdoor heat exchanger of the air conditioner; when the air conditioner is stopped, the outdoor heat exchanger of the air conditioner needs to be cleaned, the cleaning device is directly controlled to start, and the water tank 1 is controlled to rotate as needed to drive the water spray assembly to clean multiple positions of the outdoor heat exchanger of the air conditioner; when the outdoor unit fan 2 of the air conditioner is running and rotates, and the outdoor heat exchanger needs to be cleaned, the electromagnetic clutch is controlled to be energized to realize the connection between the cleaning device and the outdoor unit fan, and the outdoor unit fan can drive the water tank 1 and the water spray assembly to rotate, and because the rotation speed of the outdoor unit fan is different and the centrifugal force is different, the position of the nozzle on the water spray assembly can be changed to achieve cleaning of multiple positions of the outdoor heat exchanger.

[0060] This embodiment also provides a method for cleaning an outdoor heat exchanger of an air conditioner, including: step 100, obtaining the dust concentration on the outdoor heat exchanger of the air conditioner; step 200, when the dust concentration is greater than or equal to a preset concentration, controlling a cleaning device to start, the cleaning device being the cleaning device of the outdoor heat exchanger of the air conditioner in any of the above embodiments.

[0063] The operating modes of the air conditioner are different. In order to clean the outdoor heat exchanger of the air conditioner without affecting the heat exchange effect of the outdoor heat exchanger, the present embodiment obtains the operating mode of the air conditioner and the temperature of the water tank in the cleaning device; according to the operating mode of the air conditioner and the temperature of the water in the water tank, the operation of the cleaning device is controlled.

[0064] In one embodiment, when the current dust concentration of the outdoor heat exchanger is greater than or equal to the preset concentration and the air conditioner is running in the heating mode, the cleaning device is controlled to be electrically connected to the outdoor unit fan. When the outdoor unit fan rotates, it can drive the cleaning device to rotate, thereby cleaning multiple positions of multiple air-conditioning outdoor heat exchangers, thereby expanding the cleaning area; further, when the temperature in the water storage tank is greater than or equal to the preset temperature, the temperature of the water in the water storage tank is high at this time, and the heat exchange effect of the outdoor heat exchanger is less affected during the cleaning of the outdoor heat exchanger, and the water in the water storage tank can be directly sprayed out through the nozzle to clean the outdoor heat exchanger; when the temperature of the water in the water storage tank is less than the preset temperature, the temperature of the water in the water storage tank is low at this time, and directly spraying the water through the nozzle to clean the outdoor heat exchanger will affect the heat exchange effect of the outdoor heat exchanger. In this embodiment, the heating device is controlled to start so that the heated water enters the high-pressure water pipe and is sprayed out through the nozzle to clean the outdoor heat exchanger. At the same time, the temperature of the outdoor heat exchanger can also be increased, thereby improving the heat exchange effect of the air conditioner outdoor heat exchanger.

[0065] In another embodiment, when the current dust concentration of the outdoor heat exchanger is greater than or equal to a preset concentration and the air conditioner is operating in a cooling mode, the cleaning device is controlled to be electrically connected to the outdoor unit fan, and the outdoor unit fan can drive the cleaning device to rotate while rotating, thereby cleaning multiple positions of multiple air conditioner outdoor heat exchangers to expand the cleaning area; further, when the temperature of the water in the water tank is lower than the preset temperature, the temperature of the water in the water tank is low, and during the cleaning process of the outdoor heat exchanger, the temperature of the outdoor heat exchanger can be lowered, thereby improving the heat exchange effect of the outdoor heat exchanger.

[0066] In this embodiment, when the current dust concentration of the outdoor heat exchanger of the air conditioner is greater than or equal to the preset concentration and the air conditioner is in operation, the cleaning device is controlled to be connected to the outdoor fan so that the outdoor fan can drive the cleaning device to rotate while rotating, thereby cleaning multiple positions of multiple outdoor heat exchangers of multiple air conditioners to expand the cleaning area; further, according to the relationship between the temperature of the water in the water tank and the preset temperature, the start and stop of the heating device are controlled, and in the process of cleaning the outdoor heat exchanger, the temperature of the outdoor heat exchanger can be effectively increased or decreased, thereby improving the heat exchange effect of the outdoor heat exchanger.

[0067] On the basis of the above embodiment, the method for cleaning an outdoor heat exchanger of an air conditioner further includes: controlling the outdoor fan to cyclically rotate at multiple speeds.
