Abstract

The invention relates to the technical field of intelligent air conditioners, and discloses a method for controlling defrosting of an air conditioner. An indoor unit of the air conditioner comprises an indoor air outlet, an outdoor air outlet and an indoor fan, the indoor air outlet is provided with an air deflector, and the method comprises the steps that the operation state of the air conditioner is obtained; and when the operation state of the air conditioner is a defrosting state, the air deflector is controlled to close the indoor air outlet, and the indoor fan is controlled to blow out indoor airflow from the outdoor air outlet. The indoor unit of the air conditioner is provided with the indoor air outlet and the outdoor air outlet, the air deflector is controlled to be closed and the indoor fan is controlled to blow out the indoor airflow from the outdoor air outlet when the air conditioner is in the defrosting state, cold air can be prevented from being blown into a room, the indoor temperature fluctuation is prevented from being too large, and the user experience is improved. The invention further discloses a device for controlling defrosting of the air conditioner and the air conditioner.

Description

technical field [0001] The present application relates to the technical field of intelligent air conditioners, for example, to a method and device for controlling defrosting of an air conditioner, and an air conditioner. Background technique [0002] When the air conditioner is running for heating, the refrigerant releases heat in the indoor heat exchanger and then flows to the outdoor heat exchanger to absorb heat, resulting in a lower temperature in the outdoor heat exchanger. If the outdoor temperature is low and the humidity is high, the surface of the outdoor heat exchanger is prone to frost. When the outdoor heat exchanger is frosted, since the frost layer covers the surface of the outdoor heat exchanger, the heat exchange between the outdoor heat exchanger and the outside is affected, thereby affecting the indoor heating effect. [0003] At present, when the air conditioner is defrosting, some air conditioners operate to cool down, so that the outdoor heat exchanger ...
