Specifically, the water inlet of the water collecting pump 4 is communicated with the water receiving tank of the water receiving disc 2 through a pipeline, and the water outlet of the water collecting pump 4 is communicated with the inner cavity of the water storage tank 3 through a pipeline. When the control module detects that water in the water storage tank 3 is lack of water, the water collecting pump 4 is started, so that condensed water in the water receiving disc 2 is conveyed into the water storage tank 3.

In one embodiment of the present application, t2 is 2h. When the air conditioner is used for refrigerating, the air conditioner operates the humidifying function for less than 2 hours, and when the room temperature is reduced to the target temperature. The mode of detecting the room temperature may be to provide a temperature sensor 13 for detecting the room temperature on the air conditioner and connect the temperature sensor 13 with a control module of the air conditioner. The temperature sensor 13 detects the room temperature, and if the room temperature has fallen to the target temperature, the room humidity and the target humidity are determined. The manner of detecting the humidity of the room may be to provide a humidity sensor 14 for detecting the humidity of the room on the air conditioner and connect the humidity sensor 14 with a control module of the air conditioner. And if the room humidity is lower than the target humidity by 5%, the humidifying function is operated. If the room humidity is higher than the target humidity by 5%, the humidifying function is turned off.
