Problems solved by technology

[0003] The cleaning method of air conditioners in the prior art usually adopts manual cleaning or artificially controlled cleaning. Among them, the manual cleaning method requires the filter to be disassembled and then cleaned, which is time-consuming and laborious to clean, and the operation is troublesome; the artificially controlled cleaning method is used , it is impossible to accurately know the dust accumulation of the filter. The user can only operate the remote control to realize the self-cleaning of the filter by feeling, and cannot automatically turn on the self-cleaning function. Cleaning mode may affect the performance of the air conditioner and affect the health of the user

Embodiment 1

[0040] See attached figure 1 , the first aspect of the present invention provides a filter self-cleaning control method, the method includes: a first dust concentration preset value C;

[0041] The air conditioner turns on the windshield and runs for the first preset time t1, and detects the second dust concentration C2;

[0042] According to the size relationship between the second dust concentration C2 and the first dust concentration preset value C, it is judged whether the air conditioner enters the self-cleaning mode of the filter screen.

[0043] Therefore, the present invention detects the dust concentration, and according to the relationship between the dust concentration and the first dust concentration preset value, automatically judges whether the air conditioner enters the self-cleaning mode of the filter screen, realizes timely and automatic dust removal, so as to prevent the performance of the air conditioner from being affected, and improves user performance. T...

Embodiment 2

[0046] See attached figure 2 , the method includes: before the air conditioner operates with the windshield turned on, detecting a first dust concentration C1, where the first dust concentration C1 is an initial static dust concentration;

[0047] The air conditioner turns on the windshield and operates for the first preset time t1, and detects the second dust concentration C2, and the second dust concentration is a dynamic dust concentration;

[0048] When the second dust concentration C2 is greater than the first dust concentration preset value C, it is further determined whether the air conditioner enters the filter according to the magnitude relationship between the second dust concentration C2 and the first dust concentration C1 Self-cleaning mode.

[0049] If the absolute value of the difference between the second dust concentration C2 and the first dust concentration C1 is greater than the second dust concentration preset value Ca, the air conditioner enters the filte...

Embodiment 3

[0055] See attached image 3 , including the third odor concentration preset value Ya;

[0056] Before the air conditioner runs with the windshield turned on, the first dust concentration C1 is detected;

[0057] The air conditioner turns on the windshield and runs for the first preset time t1, and detects the second dust concentration C2;

[0058] When the second dust concentration C2 is less than or equal to the first dust concentration preset value C, detect the odor concentration Y of the air conditioner;

[0059] It is judged that when the peculiar smell concentration Y is greater than or equal to the third peculiar smell concentration preset value Ya, the user chooses to clean or not to clean, otherwise, the air conditioner operates normally.

[0060] In addition to dust, mosquito corpses, insect eggs, etc. will also cause the filter to be dirty and blocked. When the dust concentration is relatively low, an auxiliary method can be used to detect whether it needs to be ...

Abstract

The invention relates to a filtering screen self-cleaning control method and control device, and an air conditioner. The filtering screen self-cleaning control method comprises the following steps ofdetermining a first dust concentration preset value C; starting a windshield of the air conditioner for operating for a first preset time t1, and detecting a second dust concentration C2; and determining whether the air conditioner enters a filtering screen self-cleaning mode according to the relationship between the second dust concentration C2 and the first dust concentration preset value C. According to the filtering screen self-cleaning control method and control device, and the air conditioner, whether the air conditioner enters the filtering screen self-cleaning mode is automatically determined according to the relationship between the dust concentration and the first dust concentration preset value by detecting the dust concentration; and dust is automatically removed in time so asto prevent the performance of the air conditioner from being affected and improve the user experience, which is beneficial to the physical health of a user.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a method for controlling self-cleaning of a filter screen, a control device and an air conditioner. Background technique [0002] With the development of air-conditioning technology and the improvement of people's living standards, the use of air-conditioning is becoming more and more extensive. The air conditioner has the function of cooling / heating. With the accumulation of the use time of the air conditioner, the dust accumulation on the filter at the air inlet of the air conditioner will increase, and there will even be mosquito corpses and insect eggs, which will breed a large number of bacteria to a certain extent, resulting in The air intake is reduced, so the filter screen of the air conditioner needs to be cleaned in time. [0003] The cleaning method of air conditioners in the prior art usually adopts manual cleaning or artificially controlled cleaning...
