Air conditioner control method and air conditioner

Abstract

The present invention proposes an air conditioner control method, comprising: controlling to stop driving the fan motor, and the fan motor starts to decelerate; obtaining the deceleration time for the fan motor to reduce a certain speed and / or the deceleration rate during the deceleration process of the fan motor; according to the deceleration time And / or the deceleration rate determines the level of dirty blockage of the filter screen; because the wind resistance of the air duct of the air conditioner changes after the filter screen is dirty, after the drive to the fan motor is stopped, the fan motor decelerates freely, and due to the change of wind resistance, the fan motor reduces a certain speed The deceleration time and the deceleration rate in the deceleration process are different. Using the deceleration time and deceleration rate of the fan motor of the air conditioner to judge the dirty and clogged condition of the filter screen does not need to add an additional detection mechanism, which reduces the detection cost and has a high detection accuracy; it is also proposed An air conditioner includes a fan, a fan motor, a filter screen and a control board. The control board collects the rotation speed signal of the fan motor and judges the dirt blockage level of the filter screen according to the signal of the fan motor.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner control method and an air conditioner. Background technique [0002] With the improvement of people's living standards, people's requirements for the living environment are also getting higher and higher, and air conditioners have become one of the indispensable household appliances. The filter screen of the air conditioner is easy to get dirty and clogged after a long time of use, which will easily lead to a decline in the air quality in the room. At present, the dirty and clogged condition of the filter in the industry can be fed back through the cumulative use time of the air conditioner. Due to the differences in the use environments of different air conditioners, this method cannot accurately feedback the dirty and clogged condition of the filter; in addition, it can also Add an infrared sensor to the air conditioner, and use the infr...

After a long time of use, the filter of the air conditioner is easy to get dirty and clogged, and the dirty and clogged filter will easily lead to a decline in the air quality in the room

At present, the dirty and clogged condition of the filter in the industry can be fed back through the cumulative use time of the air conditioner. Due to the differences in the use environments of different air conditioners, this method cannot accurately feedback the dirty and clogged condition of the filter; in addition, it can also Add an infrared sensor to the air conditioner, and use the infrared sensor to detect the degree of dirt on the surface of the filter to indicate the dirt and blockage of the filter. Although this type of solution has high precision, the cost is relatively high; The air pressure difference is used to judge the dirty and clogged condition of the filter. This kind of detection mechanism is more complicated and the cost is relatively high. Therefore, there is still a lack of cost-effective detection solutions in the filter dirty and clogged detection industry.
