When humidifying the indoor environment and/or cleaning the evaporator 1, the water in the water tray 11 is not discharged to the outside of the air conditioner. The drain pan 11 collects water flowing down from the evaporator 1 without being discharged to the outside of the air conditioner. The water collecting tray 11 collects water for washing the evaporator 1, the water flows into the water tank 3 through the water outlet for recycling and flows into the water tank 3 again, the water flowing into the water collecting tray 11 and flowing into the water tank 3 is pumped into the evaporator 1 through the water adding pump 4 and the water adding pipe 5, and the water for washing the evaporator 1 is recycled, so that resource waste is avoided.
After the first preset time of circulation, the water in the water receiving tray 11 is discharged to the outside of the air conditioner. The first preset time is set according to a user's requirement, and may be, for example, 5 minutes or 8 minutes, during which the evaporator 1 of the air conditioner is dirty, and the water deposited from the evaporator 1 is dirty, so that the first preset time is set to be relatively short. After the first preset time of circulation, the water in the water pan 11 is discharged to the outside of the air conditioner, that is, dirty water is discharged to the outside, and then clean water is circulated.
Based on the water washing control device for the evaporator of the air conditioner, the invention also provides the air conditioner, the air conditioner comprises the evaporator, a water tank, a water adding pump, a water adding pipe and a water receiving disc, the water washing control device for the evaporator of the air conditioner runs on the air conditioner, and the indoor environment is humidified or the evaporator of the air conditioner is washed by controlling the evaporator, the water tank, the water adding pump, the water adding pipe and the water receiving disc. The air conditioner of the embodiment obtains the precipitation quantity of the evaporator through obtaining the precipitation influence factor of the evaporator and calculating according to the influence factor, and then controls the water discharge of the water pan through the precipitation quantity. Need not to set up water level switch or the drain pump is normally opened, provides an intelligent air conditioner drainage control mode, and the drainage is opened to the rational control drain pump, has improved air conditioner drainage control degree of accuracy.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
