Problems solved by technology

[0002] After the air conditioner is used for a long time, if it is not cleaned in time, more and more dirt will accumulate in the heat exchanger, and because of the poor air quality, the dirty blockage of the air conditioner heat exchanger will become more and more serious, and the indoor unit will be polluted. There are dust, oil and other substances that are difficult to clean, which pose a huge threat to human health.
The existing self-cleaning function of the air conditioner, for dust, oil and other difficult-to-clean substances, only performs a single self-cleaning effect, and for users, it is too cumbersome to press the button frequently to enter the self-cleaning, and the user experience is poor
At the same time, because the air conditioner is located in different indoor environments, when the indoor environment humidity is low, the thickness of the frost on the heat exchanger is not enough, the amount of condensed water is not enough, and the increase of the self-cleaning operation time will lead to large fluctuations in the indoor temperature, which will also affect the self-cleaning of the air conditioner. cleaning effect

Embodiment Construction

[0011] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0012] Such as figure 1 As shown, an air-conditioning self-cleaning control method based on humidity detection, by adding a humidity sensor to the air-conditioning internal unit, detects the indoor ambient humidity RH, and controls the running time of the internal fan and the stop of the internal fan during self-cleaning frosting according to the indoor ambient humidity RH time.

[0013] In this embodiment, when RH≥75%, the internal fan will stop after running for 3 minutes, and start the first defrosting after stopping for 5 minutes; after the first defrosting is completed, it will directly enter the self-cleaning again: after the internal fan runs for 3 minutes Stop, stop for 5 minutes and start the second defrosting; after the second defrosting is completed, when RH≥70%, the internal fan will stop after running for 3 minutes, and start the third defrostin...

Abstract

The invention discloses an air conditioner self-cleaning control method based on humidity detection, and relates to the technical field of air conditioner control. According to the air conditioner self-cleaning control method, when an air conditioner conducts self-cleaning, indoor environment humidity is synchronously detected, and operation time and stop time of a fan in the air conditioner are controlled based on different indoor environment humidity. Meanwhile, the amount of condensed water in a self-cleaning start stage is guaranteed to be sufficient, the self-cleaning time is shortened, the temperature fluctuation is reduced, multiple self-cleaning can be carried out, the better cleaning effect is ensured, and the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning control, in particular to an air-conditioning self-cleaning control method based on humidity detection. Background technique [0002] After the air conditioner is used for a long time, if it is not cleaned in time, more and more dirt will accumulate in the heat exchanger, and because of the poor air quality, the dirty blockage of the air conditioner heat exchanger will become more and more serious, and the indoor unit will be polluted. There are dust, oil and other substances that are difficult to clean, which pose a huge threat to human health. The existing self-cleaning function of the air conditioner only performs a single self-cleaning effect on difficult-to-clean substances such as dust and oil, and for users, it is too cumbersome to press the button frequently to enter the self-cleaning, and the user experience is poor. At the same time, because the air conditioner is located in di...
