Air conditioner sterilization control method, control device and air conditioner

Abstract

The application provides a control method and device for sterilization of an air conditioner and the air conditioner. The method comprises: obtaining a first concentration when the duration of a first sterilization mode of the air conditioner reaches a first duration, the first sterilization mode being a mode in which the solution after electrolysis in a water tank is statically sterilized, and the first concentration being the residual concentration of hypochlorous acid in the solution in the water tank when the duration of the first sterilization mode reaches the first duration; in the case that a humidifying instruction is received and the first concentration is greater than or equal to a first threshold value, heating the solution to a first target temperature until the solution at the first target temperature lasts for a second duration, and controlling the air conditioner to switch to a humidifying mode; in the case that a humidifying instruction is received and the first concentration is less than the first threshold value, controlling the air conditioner to switch to the humidifying mode. The method solves the problem that in the prior art, after sterilization by electrolysis, direct humidification is performed, which causes residual hypochlorous acid to enter the indoor environment with water mist, affecting the health of users.
