Cleaning reminder method and device for air conditioner filter

Abstract

The invention provides a cleaning prompt method and device for an air conditioner filter, and relates to the field of air conditioner cleaning. The air-conditioning filter screen cleaning reminder device and method detect the first ultrasonic wave emitted by the ultrasonic transmitter toward the filter screen; then detect the second ultrasonic wave generated after the first ultrasonic wave is processed by the filter screen, and when the second ultrasonic wave is relatively When the change of the first ultrasonic wave is within the preset first threshold range (at this time, the degree of dust accumulation on the filter screen is relatively serious), a cleaning reminder message is generated, thereby realizing automatic real-time reminder to the user to clean the filter screen in time Cleaning will not affect the ventilation rate, improve the cooling and heating effects of the air conditioner, and reduce power consumption, and because of the strong penetrating power of ultrasonic waves, the detection results are also very sensitive and accurate.

Description

technical field [0001] The invention relates to the field of air conditioner cleaning, in particular to a method and device for prompting cleaning of an air conditioner filter. Background technique [0002] When the air conditioner exchanges heat with the indoor environment, it mainly drives the airflow through the fan to bring the heat or cold of the indoor heat exchanger into the air, and the fan will inevitably bring indoor dust and other impurities into the heat exchanger during operation. , When there is a lot of dust in the heat exchanger, it will affect the heat exchange effect. Therefore, before the air enters the air conditioner, a filter is installed to block dust and other impurities outside the heat exchanger. As the air conditioner is used for a long time, a large amount of dust and impurities will accumulate on its filter. When the dust and impurities accumulate too much, the air volume entering the air conditioner will decrease, resulting in a decrease in heat...

AI Technical Summary

Problems solved by technology

As the air conditioner is used for a long time, a large amount of dust and impurities will accumulate on the filter. When the dust and impurities accumulate too much, the air volume entering the air conditioner will decrease, resulting in a decrease in the heat exchange effect.

However, due to the high location of the air conditioner, it is difficult to detect the degree of dust accumulation on the filter screen, and too frequent cleaning will bring some unnecessary troubles to the user

[0003] At present, none of the air conditioners on the market has a detection function, which makes it impossible to judge the degree of dust accumulation. Users do not know when to clean the filter screen. Generally, they have never cleaned it. Cooling and heating effects, and increase the power consumption of the air conditioner
