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
[0036] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0037] The main core idea of the dirty blockage detection scheme of the air conditioner proposed by the present invention is that, according to the motor characteristics of the air conditioner, the motor speed changes with the load under the same voltage. Small, the characteristics of the speed increase. When the air conditioner enters the dirty blockage detection mode, after adjusting the motor input voltage of the air conditioner to the target voltage corresponding to the current operation mode, obtain the measured speed of the motor and the current operating wind speed, according to the time when the motor is running in the current operating wind speed As a result of comparing the corresponding target speed with the measured speed, it is determined whether the indoor unit of the air conditioner is dirty or not. ...

The invention discloses a filth blockage detecting method for an air conditioner. The method comprises the steps that when the air conditioner enters a filth blockage detecting mode, the current running mode of the air conditioner is obtained; the input voltage of a motor of the air conditioner is adjusted to the target voltage corresponding to the current running mode; the actually-measured rotating speed and the current running air gear of the motor are obtained; and when the motor runs at the current running air gear, the corresponding target rotating speed is compared with the actually-measured rotating speed, and according to the comparison result, whether filth blockage happens to an indoor unit of the air conditioner or not is judged. The invention further discloses a filth blockage detecting device for the air conditioner. According to the filth blockage detecting method and device, by means of the comparison of the rotating speeds of the motor under the same target voltage, whether filth blockage happens to the indoor unit of the air conditioner or not is judged, the convenience of filth blockage detection on the indoor unit of the air conditioner is improved, and accordingly 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...
