Air conditioner evaporator cleaning control method and device and air conditioner

Abstract

The invention discloses an air conditioner evaporator cleaning control method. The method comprises the following steps: (A) when an evaporator is cleaned, a compressor is controlled to start to enter a refrigerating mode, and a water adding pump is controlled to periodically start by a first preset time and to stop by a second preset time; and water added in the water pump is filled in the evaporator through a water adding pipe; (B) after icing on the evaporator satisfies preset conditions, the compressor is controlled to enter a heating mode to melt ice on the evaporator to flow into a water receiving disc to clean the evaporator; and (C) the water in the water receiving disc is drained to the external of the air conditioner. The invention further discloses an air conditioner evaporator cleaning control device and an air conditioner. The air conditioner evaporator cleaning control method improves the evaporator cleaning effect, improves the indoor environment, and improves the air conditioner comfort.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a cleaning control method and device for an evaporator of an air conditioner and an air conditioner. Background technique [0002] At present, with the continuous development of science and technology, more and more home appliances have entered people's daily life and work. Household appliances take an air conditioner as an example. The air conditioner can provide a cooling or heating effect for an indoor environment through heat exchange in a cold or hot environment, so as to provide a comfortable indoor environment. However, as the air conditioner works for a long time, the evaporator of the indoor unit will become dirty, causing the wind blown into the indoor environment to carry bacteria, making the indoor ambient air worse and the air conditioner poor in comfort. [0003] The above content is only used to assist in understanding the technical solution of the presen...
