Step S10, when the evaporator is cleaned, controlling the compressor to enter the cooling mode, and controlling the watering pump to periodically start the first preset time, stopping the second preset time, and the water of the water pump is driven into the evaporator through the water pipe;

Referring to FIGS. 2a and 2b, an air conditioner according to an embodiment of the present invention includes: an evaporator 1, a water tank 2, a water tank 3, a watering water pump 4, and a water supply pipe 5, and a bottom of the evaporator 1 is provided with a water receiving tray 11, the water tank 2 is connected to the water tank 3, the watering water pump 4 is disposed in the water tank 3, one end of the water supply pipe 5 is connected to the watering water pump 4, and the other end is opposite to the evaporator 1, to the evaporator 1 spray water to the room to evaporate water. Further, the water receiving tray 11 is provided with a drain port 14 to which the first drain pipe 15 is connected, and the first drain pipe 15 is provided with a drain valve 16. The drain pipe 15 is connected to an outdoor or indoor drain. Optionally, in order to facilitate the laying of the pipeline, the drain opening 14 is disposed at an end of the water receiving tray 11 away from the water outlet 12. A drain port 14, a first drain pipe 15, and a drain valve 16 are disposed in the water receiving tray 11, and the water in the water receiving tray 11 is discharged to the outside through the drain port 14 and the first drain pipe 15, and the water receiving tray is controlled by the drain valve 16. The water of 11 is discharged to the outside or stored in the water receiving tray 11. The water is drained to the outside through the drain port 14, and the water left in the water receiving tray 11 is discharged in time to avoid water leakage inside the air conditioner. In another embodiment of the present invention, the water in the water tray 11 can also be drained to the outside of the air conditioner by the drain pump 17 and the second drain pipe 18.

When it is necessary to clean the evaporator 1 of the air conditioner, the water pump 4 is controlled to be turned on. After the water pump 4 is turned on, the water pump 4 pumps the water flowing into the water tank 3 into the water tank 5 into the water supply pipe 5. Determine whether the evaporator 1 needs to be cleaned by the running time of the air conditioner, and control the evaporator 1 of the air conditioner when the running time reaches the threshold (one month or one quarter, etc., or the continuous running time reaches 300 hours or 400 hours, etc.) Cleaning; or receiving the evaporator 1 cleaning command of the air conditioner to clean the evaporator 1 of the air conditioner. After the water pump 4 is controlled to draw water into the water supply pipe 5, the water supply pipe 5 is controlled to inject water into the evaporator 1 to clean the evaporator 1.
