Problems solved by technology

Sometimes, simply relying on self-cleaning by first frosting and then defrosting will not completely clean the indoor heat exchanger, especially when there are some large dirty cobwebs, it is difficult to be taken away by the defrosting water

Abstract

The invention belongs to the technical field of air conditioners, and particularly provides a self-cleaning control method for an air conditioner. In order to improve the self-cleaning effect of the air conditioner, the air conditioner comprises an indoor unit, an air ejector fan and an air supply fan, the air ejector fan and the air supply fan are arranged on the indoor unit, the air ejector fanis used for extracting dust on a heat exchanger of the indoor unit out of a room, and the air supply fan is used for blowing up dust on the heat exchanger to assist the air ejector fan in extracting dust out of the room. The self-cleaning control method for the air conditioner comprises the steps that air is blown to the heat exchanger of the indoor unit; the concentration of dust blown up from the heat exchanger is detected; and according to the dust concentration, whether the air ejector fan needs to be started or the air supply fan needs to be stopped is judged. Whether the air supply fan and the air ejector fan are made to be in a started state so as to collect dust on the heat exchanger is judged according to the dust degree of the heat exchanger, and therefore the opportunity of dustcollection and cleaning for the heat exchanger is accurately determined.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides an air conditioner self-cleaning control method. Background technique [0002] The air conditioner is a device that can cool / heat the room. As time goes by, the dust accumulation on the indoor unit of the air conditioner will gradually increase. When the air conditioner is turned on, it will carry a lot of dust and bacteria, so it is necessary to clean the air conditioner in time. At present, most air conditioners adopt the self-cleaning method, that is, by controlling the operation of the indoor unit, the evaporator is first frosted and then defrosted, and the evaporator is cleaned by defrosting. Sometimes, simply relying on self-cleaning by first frosting and then defrosting will not completely clean the indoor heat exchanger, especially when there are some large dirty cobwebs, it is difficult to be taken away by the defrosting water. [0003] Therefore, the...
