[0021] According to the self-cleaning control device of the utility model, the warning module is wirelessly connected to a terminal device for sending warning information.

[0022] An air conditioner with the self-cleaning control device comprises a housing, wherein the housing has an air inlet and an air outlet; a humidity sensor and a temperature sensor are arranged near the air inlet and the air outlet; and an air volume sensor is also arranged at the air outlet;

[0023] The temperature and humidity values ​​of the air inlet and outlet are detected by the humidity sensor and the temperature sensor, and the air volume at the air outlet is detected by the air volume sensor to determine whether to start the self-cleaning mode.
