Dust removal method of filter screen of air conditioner, and air conditioner

Abstract

The invention discloses a dust removal method of a filter screen of an air conditioner and the air conditioner. The dust removal method comprises the following steps that the first pressure value P0 of an air inlet side and the second pressure value P1 of an air outlet side of a current filter screen are detected at a time T interval, and a first difference PX is obtained through calculation; the first difference PX is compared with a prestored second difference PA, and when a difference deltaPB between the first difference PX and the second difference PA is larger than or equal to the first preset threshold value K1, or is smaller than the second preset threshold value K2, a blower is reversed; a real-time deltaPB is detected in time and calculated when the blower is reversed, and the real-time deltaPB is compared with an initial preset threshold value K0; when the real-time deltaPB is larger than the initial preset threshold value K0, the first duration that the real-time deltaPB is larger than the initial preset threshold value K0 is counted, and if the first duration is equal to the preset duration, reversing of the blower is stopped; and when the real-time delta PB is smaller than or equal to the initial preset threshold value K0, reversing of the blower is finished. Through the adoption of the technical scheme, dust on the filter screen can be conveniently and quickly removed.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for removing dust from a filter screen of an air conditioner and the air conditioner. Background technique [0002] The dust-removing mode of existing air conditioner mainly is to arrange air filter screen at the air inlet to absorb the dust in the air. However, after the air conditioner has been used for a period of time, a thick dust layer will form on the filter, and the dust on the filter will greatly reduce the cooling capacity of the air conditioner and increase operating costs. At the same time, the dust accumulated on the filter net is easy to breed bacteria, and some dust may enter the indoor air again with the circulating air flow, which will affect the indoor air quality. [0003] Some air conditioners have adopted a special dust removal device for loading to remove the dust, but these structures are independent of the design of the air conditioner, ...

AI Technical Summary

Problems solved by technology

If the brush structure is added to remove dust from the filter, the structure of the air conditioner becomes complicated, assembly and processing are difficult, and the production cost is increased.
