Air conditioner and self-cleaning method thereof

Abstract

The invention provides an air conditioner and a self-cleaning method thereof, and belongs to the technical field of air conditioners. The air conditioner comprises a control unit, wherein the control unit comprises a processor and a memory, a program and a preset parameter table are stored in the memory, when the program is executed by the processor, the method can be used for realizing the following steps of acquiring the indoor environment humidity; acquiring time and compressor frequency data according to the indoor environment humidity and the preset parameter table; controlling a compressor to run in a dehumidification mode according to the acquired compressor frequency F1 and the time T1 so as to forming condensed water on the surface of an evaporator; adjusting the frequency of the compressor to operate a refrigerating mode at a frequency higher than F2 so as to enable the condensed water to be iced, reducing the frequency of the compressor to rotate in F2 for T2 duration when the running duration reaches the preset time so as to enable the condensed water continues to be frosted; and controlling the air conditioner to enter a heating mode to carry out defrosting. The method has the advantages of being good in cleaning effect and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner and a self-cleaning method thereof. Background technique [0002] The air conditioner cools or heats by circulating air. During the air circulation process, the dust in the air is very easy to adhere to the surface of the evaporator. The traditional method is to disassemble the machine and clean it before installing it, which brings extremely bad use to the user. Experience, in order to correct this shortcoming, the concept of increasing the self-cleaning function of the air conditioner was proposed. [0003] The self-cleaning mode of the air-conditioning evaporator is recorded in the specification disclosed in the Chinese invention patent application CN108489030A, and the self-cleaning process of cooling and frosting, heating and defrosting, air drying and sterilization is performed in sequence, so as to realize intelligent cleaning of the...

AI Technical Summary

Problems solved by technology

The existing self-cleaning technology operates the air conditioner in the cooling state, closes the damper, stops the indoor fan, and the compressor operates at an appropriate frequency to make the evaporator of the indoor unit frost. After an appropriate time, it turns to heating to defrost. Take away the dirt to achieve the purpose of cleaning, but the ability to decontaminate more serious dirt is limited, and for low humidity seasons or dry areas with poor frosting ability, good frosting cannot be achieved within a fixed frosting time Frost effect, resulting in poor decontamination effect
