Embodiment 1

[0047] First refer to figure 1 , to describe Embodiment 1 of the self-cleaning control method for an air conditioner of the present invention. in, figure 1 It is a flow chart of Embodiment 1 of the self-cleaning control method for an air conditioner of the present invention.

[0048] Such as figure 1 As shown, in order to solve the problem that the existing air conditioner cannot accurately judge the timing of turning on the self-cleaning mode, in the technical solution of the present invention, the air conditioner includes an indoor unit, and a heat exchanger is arranged in the indoor unit for the air conditioner. Self-cleaning control methods include:

[0049] S100, judging whether the humidity of the heat exchanger reaches the standard;

[0050] During the use of the heat exchanger of the indoor unit, especially in the case of high indoor humidity in summer, more water droplets will adhere, and these water droplets will affect the air outlet of the heat exchanger and th...

Embodiment 2

[0086] Refer below Figure 1 to Figure 3 , to describe the second implementation of the self-cleaning control method for the air conditioner of the present invention. in, image 3 It is a flow chart of Embodiment 2 of the self-cleaning control method for an air conditioner of the present invention.

[0087] In steps S409, S413 and S417, it is mentioned that the outlet wind speed is compared with the standard wind speed under different standard working conditions to obtain the actual cleanliness of the heat exchanger, which is feasible for a brand new air conditioner, however, the air conditioner After a long period of use, the aging of the fins of the heat exchanger and the aging of the motor will reduce the standard value of the indoor air volume and wind speed of the air conditioner. The difference between the outlet wind speed and the standard wind speed is too large, and then directly enters the self-cleaning mode, but this is obviously not caused by the increase of impu...

Abstract

The invention belongs to the field of air conditioners, and particularly provides a self-cleaning control method for an air conditioner. The problem that a conventional air conditioner cannot accurately judge the time for starting a self-cleaning mode is solved. The air conditioner comprises an indoor unit, and a heat exchanger is arranged in the indoor unit. The self-cleaning control method for the air conditioner comprises the following steps of judging whether the humidity of the heat exchanger reaches the standard or not, judging the cleanliness of the heat exchanger when the humidity of the heat exchanger reaches the standard, and selectively controlling the air conditioner to execute the self-cleaning mode according to the judgment result. By judging the humidity of the heat exchanger, the cleanliness of the heat exchanger is judged more accurately, the cleanliness of the heat exchanger is judged under a plurality of working conditions, the accuracy of the judgment result is guaranteed, and therefore the time for starting the cleaning mode can be controlled more accurately.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides a self-cleaning control method for an air conditioner. Background technique [0002] During the use of the air conditioner, since the heat exchanger of the indoor unit is used for a long time, a large amount of dust will accumulate and the cooling / heating capacity of the air conditioner will be reduced. Therefore, the heat exchanger of the indoor unit needs to be cleaned frequently. [0003] Existing technologies are usually manual cleaning or self-cleaning mode. Manual cleaning is time-consuming and costly for users. Therefore, manufacturers often set a self-cleaning mode in the air conditioner so that the air conditioner can clean itself. However, affected by factors such as the actual installation location, actual operating status, and indoor environment, the air conditioner cannot automatically judge the timing of turning on the self-cleaning control, but r...
