Problems solved by technology

[0002] During the use of the air conditioner, the filter screen of the air conditioner indoor unit and the surface of the evaporator tend to accumulate dust or be covered by debris, resulting in poor heat exchange efficiency and reduced performance of the air conditioner. Check if the air conditioner is dirty
The inconvenient detection of dirty air conditioners makes it easy for users to ignore the problem of dirty air conditioner indoor units and fail to clean them in time, resulting in a decline in the performance of the air conditioner and a decrease in user comfort during the use of the air conditioner

Embodiment Construction

[0034] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] The main core idea of ​​the air conditioner dirty blockage detection scheme proposed by the present invention is that, according to the fact that the motor has the same operating speed under different loads and the required voltage values ​​are different, when the air conditioner indoor unit is dirty blockage occurs, the load decreases , the characteristic of the voltage drop required to achieve a specific operating speed. When the air conditioner enters the dirty blocking detection mode, according to the actual measured voltage value when the motor of the air conditioner reaches the current operating speed, and the result of comparing the corresponding target voltage value and the actual measured voltage value when the motor reaches the current operating speed in the current operating mode , to determine wheth...

Abstract

The invention discloses a filth blockage detecting method of an air conditioner. The method comprises the steps of: obtaining a present operation mode and a present operation rotating speed of the air conditioner when the air conditioner enters a filth blockage detecting mode; obtaining an actual-measured voltage value when a motor of the air conditioner reaches the present operation rotating speed; comparing a corresponding target voltage value of the motor reaching the present operation rotating speed in the present operation mode with the actual-measured voltage value; and judging if an indoor unit of the air conditioner generates the filth blockage according to the comparing result. The invention further discloses a filth blockage detecting device of the air conditioner. The method judges if the air conditioner generates the filth blockage through comparing the actual-measured voltage with the target voltage of the motor under the same operation rotating speed to prompt users to timely clean the air conditioner, so that the filth blockage detecting convenience for the indoor unit of the air conditioner is improved, and the performance of the air conditioner is guaranteed.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method and device for detecting dirty blockage of an air conditioner. Background technique [0002] During the use of the air conditioner, the filter screen of the air conditioner indoor unit and the surface of the evaporator tend to accumulate dust or be covered by debris, resulting in poor heat exchange efficiency and reduced performance of the air conditioner. Check to see if the air conditioner is dirty. The inconvenientness of the air conditioner to detect the dirty blockage makes it easy for users to ignore the problem of dirty blockage of the indoor unit of the air conditioner, and cannot clean it in time, resulting in a decrease in the performance of the air conditioner and a decrease in user comfort during the use of the air conditioner. Contents of the invention [0003] The main purpose of the present invention is to provide a method and device for detect...
