Problems solved by technology

[0004] After the air conditioner completes the self-cleaning operation, the internal environment of the air conditioner is relatively humid, which is very easy to breed bacteria and aggravate the corrosion of the aluminum foil of the air conditioner heat exchanger, thereby reducing the use experience of the air conditioner and reducing the service life of the air conditioner

Abstract

The invention relates to the technical field of intelligent air conditioners, and discloses a control method used for self-cleaning of an air conditioner. The control method comprises the steps that after an air conditioner self-cleaning instruction is received, the air conditioner is controlled to execute self-cleaning operation including a frosting stage and a defrosting stage; and under the condition that the air conditioner completes self-cleaning operation, a fan of the air conditioner is controlled to reversely run so as to remove water on the surface of a heat exchanger of the air conditioner in a drying manner. After self-cleaning of the air conditioner is finished, the turning direction of the fan of the air conditioner is converted, through the characteristic that the fan reversely runs to generate heat, water evaporation on the surface of the heat exchanger is accelerated, the internal environment humidity of the air conditioner is reduced, bacterium breeding can be effectively avoided, the corrosion process of aluminum foil pieces of the heat exchanger of the air conditioner can be delayed, and therefore the use experience of the air conditioner is improved, and the service life of the air conditioner is prolonged. The invention further discloses a control device used for self-cleaning 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 control method and device for air conditioner self-cleaning, and an air conditioner. Background technique [0002] During the heating or cooling operation of the air conditioner, dust and large particles in the outside air will enter the air conditioner and adhere to the surface of the air conditioner heat exchanger, directly affecting the heat exchange between the heat exchanger and the outside air. And affect the air quality. In order to ensure heat exchange efficiency and air quality, it is necessary to perform self-cleaning treatment on the air conditioner heat exchanger. The self-cleaning operation of the air conditioner is mainly divided into the frosting stage and the defrosting stage. In the frosting stage, the air conditioner operates in cooling mode before the frosting stage, and the moisture in the indoor air is condensed in the form of...
