Abstract

The invention belongs to the technical field of air conditioners, and specifically provides an air conditioner self-cleaning control method. In order to improve the self-cleaning effect of the air conditioner, the air conditioner of the present invention includes an indoor unit and an exhaust fan and an air supply fan arranged on the indoor unit; the exhaust fan is used to suck out the dust on the heat exchanger of the indoor unit to the outside, The wind fan is used to blow up the dust on the heat exchanger to assist the exhaust fan to suck the dust to the outside; the self-cleaning control method of the air conditioner includes: detecting the current value I of the fan of the indoor unit at the current speed; 当前 And the coil temperature of the indoor unit and the indoor dew point temperature; compare I 当前 with I 标准 ; Judging whether the heat exchanger of the indoor unit is in a condensation state according to the coil temperature and dew point temperature; based on the condensation state and according to I 当前 with I 标准 The comparison result judges whether to start the exhaust fan and the air supply fan. The present invention can more accurately determine the timing of vacuuming and cleaning the heat exchanger by way of double judgment.

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...
