In the cooling mode in this embodiment, the indoor motor stops working, and the indoor aviation baffle is in the closed condition, avoids blowing out cold wind in the cleaning process, influences user's use experience.
The air conditioner comprises an outdoor unit, an indoor heat exchanger, a refrigerating mode and an anti-freezing protection mode, wherein the indoor heat exchanger is connected with the outdoor unit, the anti-freezing protection mode is started when the temperature of the indoor heat exchanger is lower than a preset value in order to prevent the indoor heat exchanger from freezing, and therefore the indoor heat exchanger cannot be frosted for a first preset time.
