Air conditioning outdoor unit and method for washing heat exchanger

Abstract

The embodiment of the invention discloses an air conditioning outdoor unit and a method for washing a heat exchanger and relates to the field of washing of air conditioners, aiming at improving the washing quality of washing the heat exchanger while realizing the aim of automatically washing the heat exchanger, and avoiding secondary pollution caused by residual dust. The air conditioning outdoor unit comprises a spraying device, wherein the spraying device comprises a water storage device, a water pump connected with the water storage device and a spraying pipeline connected with the water pump; the air conditioning outdoor unit further comprises a fan and a control unit; the spraying device is arranged between the fan and the heat exchanger; when the spraying pipeline sprays water, the fan rotates oppositely so that the water sprayed by the spraying pipeline is sprayed on the heat exchanger; the control unit is connected with the spraying device and the fan; the control unit is used for controlling the spraying device to do water spaying and controlling opposite rotation of the fan. The embodiment of the invention is used for washing the heat exchanger.

Description

technical field [0001] The invention relates to the field of cleaning of air conditioners, in particular to an outdoor unit of an air conditioner and a method for cleaning a heat exchanger. Background technique [0002] With the continuous improvement of people's quality of life, air conditioners are used more and more widely in ordinary households. The general household air conditioners are divided into two parts: indoor unit and outdoor unit. Both indoor unit and outdoor unit are equipped with heat exchangers. As an important part of the air conditioner, the heater directly affects the cooling and heating effects of the air conditioner. [0003] At present, the most commonly used heat exchanger is the air-source fin heat exchanger, which is an air-cooled heat exchanger that uses air to exchange heat. It is easy to install and has a simple structure. The air source fin heat exchanger is generally composed of fins, tube clusters, side plates, fans and motors. The fins are i...

Problems solved by technology

However, since the heat exchanger in the outdoor unit of the air conditioner accumulates a lot of dust and is closely attached to the fins of the heat exchanger, if water is directly sprayed on the fins of the heat exchanger, it is not easy to Wash off the dust accumulated on the fins, the heat exchanger cannot be cleaned thoroughly, the cleaning quality is poor, and the residual dust mixed with water will form dirt with stronger adhesion, causing secondary pollution
