Air conditioner and cleaning and sterilizing method thereof

Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to an air conditioner and a cleaning and sterilizing method thereof. The problem that the cleaning function and the sterilization function of an existing air conditioner can be achieved only by additionally arranging elements is solved. Therefore, the cleaning and sterilizing method comprises the steps thatthe surface temperature of an indoor heat exchanger is kept above the preset temperature; after a first preset time, an indoor fan is made to rotate reversely; and self-cleaning operation of the indoor heat exchanger is executed. Due to the fact that high temperature can completely cover each corner in an indoor unit, therefore, other sterilization components do not need to be additionally arranged in the high-temperature sterilization mode, and all bacteria in the indoor unit can be effectively killed; and then, the indoor fan is controlled to rotate reversely, so that dust, impurities and bacterium residues are attached to the surface of the indoor heat exchanger, and then the self-cleaning operation of the indoor heat exchanger is executed, so that the sterilization function and the cleaning function of the indoor unit are effectively achieved on the basis that any element does not need to be additionally arranged.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner and a cleaning and sterilization method thereof. Background technique [0002] With the continuous improvement of people's living standards, people have also put forward higher and higher requirements for the living environment. In order to maintain a comfortable ambient temperature, air conditioners have become an essential device in people's lives. In recent years, users have also put forward higher and higher requirements for the comprehensive performance of air conditioners. Taking the cleaning function and sterilization function as an example, most of the existing air conditioners only have the self-cleaning function of the outdoor unit, while the indoor unit mainly depends on the user. Self-cleaning; Of course, most of the existing air conditioners still have the function of sterilization, and the existing air conditioners usually re...
