Embodiment Construction

[0037] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the present invention.

[0038] see in conjunction figure 1 As shown, according to the embodiment of the present invention, the cleaning method for the indoor and outdoor units of the air conditioner includes: controlling the indoor heat exchanger to enter the frosting mode; Keep the evaporating temperature within the preset range to make frost on the surface of the indoor heat exchanger; the frost on the indoor heat exchanger lasts for t1 time, then reduce the frequency of the compressor, control the four-way valve to change direction, and let the outdoor heat...

Abstract

The invention discloses an air-conditioner internal and external unit cleaning method. The method comprises the steps that an indoor heat exchanger is controlled to enter a frosting mode; operation frequency of an air-conditioner, the opening degree of a throttling device and the rotating speed of an indoor fan are adjusted to enable evaporating temperature of the indoor heat exchanger to be kept within the preset range and the surface of the indoor heat exchanger to be frosted; frosting of the indoor heat exchanger lasts for time t1, later, frequency of a compressor is reduced, a four-way valve is controlled to be reversed, an outdoor heat exchanger enters a frosting mode, and meanwhile, the indoor heat exchanger is defrosted; the operation frequency of the air-conditioner, the opening degree of the throttling device and the rotating speed of an outdoor fan are adjusted, the evaporation temperature of the outdoor heat exchanger is kept within the preset range, and the surface of the outdoor heat exchanger is frosted; frosting of the outdoor heat exchanger lasts for time t2, the compressor is controlled to be shut down, and the indoor fan and the outdoor fan are kept starting until cleaning is completed. According to the air-conditioner internal and external unit cleaning method, the problem that in the prior art, the surface of the heat exchanger is cleaned through condensate water, and the effect is poor can be solved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for cleaning the inner and outer units of an air conditioner. Background technique [0002] At present, the cleaning work of the outdoor unit usually takes a long time or is never cleaned. During manual cleaning, because the heat exchanger is close to the wall, it is inconvenient to clean, resulting in incomplete cleaning. If foreign objects are used to clean, it may cause the fins to fall. Chips will affect the heat exchange effect of the heat exchanger and shorten its service life. [0003] An automatic condenser cleaning device is provided in the prior art, the cleaning device includes a cylindrical brush that is fixedly sleeved on the roller and can touch the bottom end of the fin, and the motor is movably arranged on the roller One end of the shaft, and drives the roller shaft to rotate, the roller shaft rotates and moves through the meshing of the gear an...
