Problems solved by technology

After long-term use, the filter screen accumulates a lot of impurities, which often leads to dirty clogging, which easily leads to low air volume and poor temperature adjustment effect of the air conditioner
For the treatment of dirty and clogged situations, at present, artificial timing is usually used to clean or regularly remind users to clean the filter, but the actual degree of dirty and clogged filters cannot be accurately judged
There is a risk of misjudgment in existing detection and judgment methods, resulting in unnecessary cleaning operations

Embodiment 1

[0025] An embodiment of the present invention provides a method for judging dirty blockage of an air conditioner, please refer to the following figure 1 and figure 2 , to describe this embodiment in detail.

[0026] The method comprises steps S1-S3:

[0027] Step S1, acquiring the accumulated running time of the air conditioner, and judging whether the accumulated running time exceeds a preset time threshold.

[0028] In this step, because the filter screen of the air conditioner is usually dirty and clogged after being used for a period of time, the embodiment of the present invention uses the accumulated running time of the air conditioner as the basis for preliminary judgment, which can avoid the accumulation of the air conditioner during the accumulated running time. It is short, and repeated follow-up judgments will not occur when dirty blockage occurs.

[0029] Step S2, if yes, after each start-up of the air conditioner, obtain the phase current change value of the a...

Embodiment 2

[0047] This embodiment provides a device for judging dirty blockage of an air conditioner, see image 3 , the device 400 includes: a time judging module 401, configured to obtain the cumulative running time of the air conditioner, and judge whether the cumulative running time exceeds a preset time threshold; a phase current change value obtaining module 402, used to obtain the accumulated running time of the air conditioner during the time judging module When the judgment result is yes, after each start-up of the air conditioner, the phase current change value of the air conditioner motor at different speeds is obtained, and the dirty block judgment module 403 is used to obtain the first preset number of the phase current change values, according to The first preset number of phase current change values ​​determines whether the air conditioner is dirty or blocked.

Embodiment 3

[0049] This embodiment provides a computer-readable storage medium, where a computer program is stored in the computer-readable storage medium, and when the computer program is read and executed by a processor, the method as described in the first embodiment is implemented.

Abstract

The invention provides an air conditioner filth blockage judgment method and device, a medium and an air conditioner. The method comprises the steps that S1, the accumulated running time of the air conditioner is obtained, and whether the accumulated running time exceeds a preset time threshold value or not is judged; S2, if yes, after the air conditioner is started every time, phase current change values of an air conditioner motor at different rotating speeds are obtained; and S3, a first preset number of phase current change values are obtained, and whether the air conditioner is in a filthblockage state or not is judged according to the first preset number of phase current change values. The phase current of the air conditioner motor is detected after each startup, and whether the airconditioner is in the filth blockage state or not can be effectively and accurately judged by using the first preset number of phase current change values.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a method, device, medium and air conditioner for judging dirty blockage of an air conditioner. Background technique [0002] Air conditioners usually use filter screens to filter impurities in the air, for example, filter screens are provided at the air outlets of indoor units. After long-term use, the filter screen accumulates a lot of impurities, which often leads to dirty clogging, which easily leads to low air volume and poor temperature adjustment effect of the air conditioner. For the treatment of dirty clogging, at present, artificial timing is usually used to clean or regularly remind the user to clean the filter screen, but the actual dirty clogging degree of the filter screen cannot be accurately judged. There is a risk of misjudgment in existing detection and determination methods, resulting in unnecessary cleaning operations. Contents of the invent...
