Dust removal device, air conditioner and dust removal method

Abstract

The invention relates to the technical field of dust removal, in particular to a dust removal device, an air conditioner and a dust removal method. The air conditioner comprises a fan, a heat exchanger and a dust removal device, wherein the dust removal device comprises a dust remover, the dust remover comprises a dust removal main body, a first piston and a first elastic piece, the dust removal main body is provided with a first cavity, an air vent and a jet orifice, the air vent and the jet orifice are communicated with the first cavity, the air vent is used for introducing external air, the jet orifice is used for jetting air in the first cavity, the jet orifice faces the heat exchanger, the first piston is located in the first cavity, one end of the first elastic piece is connected with the first piston, the other end of the first elastic piece is connected with the inner wall of the first cavity, and the first piston can reciprocate in the first cavity. During dust removal, a receiver receives a dust removal command, and a judger judges whether the air conditioner meets a preset dust removal operation condition or not; a controller controls the fan to rotate reversely; and the surface of the heat exchanger of the air conditioner is subjected to dust removal through the dust removal device, and the dust removal command received by the receiver is automatically received during startup and / or shutdown.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to a dust removal device, an air conditioner and a dust removal method. Background technique [0002] With the improvement of people's living standards, air conditioners have entered thousands of households to meet people's cooling or heating needs. When the air conditioner is running, it needs to introduce external air through the fan. During the long-term operation, the external air is continuously sucked and attached to the surface of the heat exchanger. After a long period of dust accumulation on the surface of the heat exchanger, the air volume decreases and the heat exchange effect decreases. Therefore, it is necessary to clean the dust on the surface of the heat exchanger in time. [0003] During dust removal, the fan is controlled to reverse, and the dust on the surface of the heat exchanger is cleaned through the dust removal device to reduce dust accumulation on the ...
