Embodiment 1

[0048] 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.

[0049] 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:

[0050] S100, judging whether the humidity of the heat exchanger reaches the standard;

[0051] 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

[0087] 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.

[0088] 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 specifically provides a self-cleaning control method used for an air conditioner. The self-cleaning control method aims at solving the problem that the existing air conditioner cannot accurately judge the time for starting the self-cleaning mode. The air conditioner comprises an indoor unit. A heat exchanger is arranged in the indoor unit. The control method includes the steps that on the basis of the standard wind speed and the wind speed of an outlet of the indoor unit, the air conditioner is selectively controlled to execute the self-cleaning mode; after the air conditioner mentioned above executes the self-cleaning mode, whether the accumulated operation time of the air conditioner reaches the preset value or not is judged; and when the accumulated operation time reaches the preset value, the standard wind speed is determined again. By means of the setting manner mentioned above, by means of the control method of the air conditioner, the self-cleaning mode can be selectively controlled to be executed on the basis of the standard wind speed and the wind speed of the outlet of the indoor unit; and furthermore, by determining the standard wind speed again after the operation time is accumulated, the execution time of the self-cleaning mode of the air conditioner can be more accurate.

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...
