Problems solved by technology

Due to the dust in the air, it has been deposited on the surface of the indoor heat exchanger for a long time, and the continuous accumulation will lead to a decrease in the heat exchange efficiency of the air conditioner, which will affect the performance of the air conditioner and reduce the heat exchange efficiency of the indoor heat exchanger. If it is cleaned, it is easy to breed bacteria in it, which will cause the air blown out from the air outl

Example Embodiment

[0036] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0037] The invention provides a cleaning control method for a heat exchanger of an air conditioner.

[0038] refer to figure 1 , figure 1 It is a schematic flow chart of the first embodiment of the heat exchanger cleaning control method of the air conditioner of the present invention.

[0039] The present embodiment provides a method for cleaning and controlling a heat exchanger of an air conditioner. The method for controlling cleaning of a heat exchanger for an air conditioner includes:

[0040] Step S10, in the cooling mode, controlling the indoor fan of the air conditioner to run at a first preset rotational speed, so that condensation water is generated on the surface of the indoor heat exchanger;

[0041] In one embodiment, a cleaning control is set on the remote control device of the air conditioner or...

Abstract

The invention discloses a cleaning control method for a heat exchanger of an air conditioner. The cleaning control method comprises the following steps: in a cooling mode, controlling an indoor fan of the air conditioner to run at a first preset rotation speed so as to generate condensed water on the surface of an indoor heat exchanger; lowering the evaporation temperature of the indoor heat exchanger or the rotation speed of the indoor fan so as to form frost or ice on the surface of the indoor heat exchanger; at the completing moment of frost or ice formation, acquiring the current outdoor temperature; when the current outdoor temperature is higher than or equal to a first preset temperature, controlling the air conditioner to switch to an air supply mode so as to defrost the air conditioner; when the current outdoor temperature is lower than the first preset temperature, controlling the air conditioner to switch to a heating mode, and after switching to the heating mode, controlling the indoor fan to run at a second preset rotation speed so as to defrost the indoor heat exchanger. The invention further discloses a cleaning control device for the heat exchanger of the air conditioner. Through the cleaning control method and the cleaning control device, automatic cleaning of the indoor heat exchanger can be achieved, so that cleaning of the air conditioner is very convenient and fast.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method and device for controlling cleaning of a heat exchanger of an air conditioner. Background technique [0002] During the use of the air conditioner, the indoor heat exchanger is in contact with the air in real time for heat exchange. Due to the dust in the air, it has been deposited on the surface of the indoor heat exchanger for a long time, and the continuous accumulation will lead to a decrease in the heat exchange efficiency of the air conditioner, which will affect the performance of the air conditioner and reduce the heat exchange efficiency of the indoor heat exchanger. If it is cleaned, it is easy to breed bacteria in it, which will cause the air blown out from the air outlet of the air conditioner to have a peculiar smell. Therefore, it is necessary to clean the surface of the indoor heat exchanger to avoid the decrease of heat exchange efficiency of the...
