Problems solved by technology

[0002] When the air conditioner is in use for a period of time, some dust and impurities will accumulate on the surface of the coil tube of the heat exchanger of the indoor unit. If it is not cleaned in time, it will not only affect the heat exchange efficiency of the heat exchanger, but also easily breed bacteria, which will cause the air conditioner to produce peculiar smell and affect the quality of the air conditioner. The air quality of the indoor environment may even affect the health of users
[0003] At present, most of the self-cleaning of the heat exchanger of the indoor unit of the air conditioner requires the user to activate the self-cleaning function through button operation. The user cannot accurately judge when the self-cleaning function needs to be activated, and cannot guarantee the timely cleaning of the heat exchanger.
In addition, after the self-cleaning of the air conditioner is completed, it does not detect whether the heat exchanger is clean, and the user cannot know how the cleaning effect is, which affects the user experience

Embodiment Construction

[0035] This embodiment firstly provides an air conditioner self-cleaning control method, figure 1 is a flow chart of an air conditioner self-cleaning control method according to an embodiment of the present invention.

[0036] Generally, when the air conditioner is used for a period of time, some dust and impurities will accumulate on the surface of the coil of the heat exchanger of the indoor unit. If it is not cleaned in time, it will not only affect the heat exchange efficiency of the heat exchanger, but also affect the air quality of the indoor environment, reducing user experience. For this reason, the heat exchanger of the indoor unit of the air conditioner needs to be cleaned regularly. Generally, the self-cleaning treatment of the air conditioner is to adjust the temperature of the coil of the heat exchanger of the indoor unit to the temperature that can generate frost or ice, so that the dust, impurities, etc. on the surface of the coil of the heat exchanger are cove...

Abstract

The invention provides a self-cleaning control method and device for an air conditioner. The self-cleaning control method comprises the steps that the current operation mode of the air conditioner is detected, and if the current operation mode of the air conditioner is a non-refrigerating mode, the air conditioner is adjusted to be in a refrigerating mode; the rotating speed of a motor of a fan of an indoor unit of the air conditioner and the first current value of the motor under the rotating speed are detected; and the first current value of the motor under the rotating speed is compared with a first preset current value of the motor under the rotating speed, if the first current value is smaller or equal to the first preset current value, a self-cleaning mode of the air conditioner is started, and self-cleaning treatment of a heat exchanger of the indoor unit is carried out. The air conditioner can start the self-cleaning function automatically, and the self-cleaning effect of the air conditioner is promoted.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to an air conditioner self-cleaning control method and device. Background technique [0002] When the air conditioner is in use for a period of time, some dust and impurities will accumulate on the surface of the coil tube of the heat exchanger of the indoor unit. If it is not cleaned in time, it will not only affect the heat exchange efficiency of the heat exchanger, but also easily breed bacteria, which will cause the air conditioner to produce peculiar smell and affect the quality of the air conditioner. The air quality of the indoor environment can even affect the health of users. [0003] At present, most of the self-cleaning of the heat exchanger of the indoor unit of the air conditioner requires the user to activate the self-cleaning function through button operation. The user cannot accurately judge when the self-cleaning function needs to be activated, and cannot gu...
