The washing control module 8 can detect pm2.5 concentration/environmental humidity of a room through the pm2.5 sensor 15 in standby and startup states, and feeds back the concentration/environmental humidity to the indicator of the display screen of the mobile phone client 6, wherein the numerical value exceeds the set humidity and is displayed in blue to indicate that the humidity is too high, the numerical value is displayed in red when the humidity is lower than the set concentration, the icon indicates dryness, and the green indicates suitability. The user can select display functions such as warm air and the like through the operation interface of the mobile phone client 6, and the mobile phone client 6 sends a signal to the cloud server 5 to the main control module 4. In addition, the mobile phone client 6 has a one-key setting function, and after the mobile phone client is selected to be started by a user, the hot air function and the water washing function can be automatically started by automatically judging the indoor temperature and humidity of the washed air-out air conditioner.
According to the air conditioner with the lower washing air outlet, the humidity sensor is used for monitoring the environment humidity, the washing rotating speed is adjusted according to the environment humidity, the temperature sensor and the heaters are used for controlling the lower washing air outlet of the air conditioner, the heaters in corresponding number are controlled according to the ratio of the actual near-ground temperature difference to the coil pipe temperature to heat, and the problems of air dryness, high pm2.5 concentration and low room bottom temperature are solved.
