Self-cleaning control air conditioner, and air conditioner self-cleaning control method and device

The invention relates to the technical field of intelligent air conditioners and discloses a self-cleaning control air conditioner, and an air conditioner self-cleaning control method and device. Theair conditioner comprises a light source and a photosensitive device which are located on the two sides of a heat exchanger. The method comprises the steps of acquiring a current induction value collected by the photosensitive device in the air conditioner under the condition of determining that the light source in the air conditioner is started; determining a current filth blockage value corresponding to the current induction value according to the corresponding relation between the stored photosensitive device induction value and the heat exchanger filth blockage value; and controlling the air conditioner to implement self-cleaning operation when the current filth blockage value is greater than the set value. Thus, through the self-cleaning control air conditioner, and the air conditioner self-cleaning control m
