Refrigerator door detection control method based on angle sensor

Abstract

The invention discloses a refrigerator door detection control method based on an angle sensor. The refrigerator door detection control method comprises the following steps that a refrigerator is powered on and initialized; the angle sensor senses angle data information of a refrigerator door, and transmits the angle data information into a refrigerator MCU control module; the refrigerator MCU control module judges the opening or closing state of the refrigerator door according to the angle data information transmitted by the angle sensor; the refrigerator MCU control module starts voice promptor starts an automatic door closing device according a processing result. By arranging the angle sensor to sense the angle data information of the refrigerator door and a box door, the refrigerator MCU control module judges the opening or closing state of the refrigerator door according to the angle data information transmitted by the angle sensor, the situation is prevented that the refrigeratordoor is not closed to cause that refrigeration is abnormal, and foods go bad, and the situation is also prevented that the door is open for a long time, more power is consumed, and the service life of the refrigerator is affected. The precision of the angle sensor can be up to 0.1-0.5 degree, and compared with a method that whether the refrigerator door is closed or not is judged by using a doorswitch, the refrigerator door detection control method is more precise and intelligent.

Description

technical field [0001] The invention belongs to the technical field of refrigerator control, in particular to a detection and control method for a refrigerator door body based on an angle sensor. Background technique [0002] The refrigerator is a product of modern society. It is a good place to store food. The refrigerator brings a lot of convenience to our daily life. While the refrigerator facilitates people's life, it is also prone to some problems caused by daily household use. It is common that the refrigerator door is forgotten to be closed, or the user leaves in a hurry when the refrigerator door is not completely closed. If this is done for a short period of time, the cooling effect of the refrigerator will not be good, and the outdoor water vapor will enter the box and form frost, which will bring about no change to the user. If the user does not close the refrigerator door for a long time, it will cause the refrigerator to compress The machine keeps working, whic...

[0002] The refrigerator is a product of modern society. It is a good place to store food. The refrigerator brings a lot of convenience to our daily life. While the refrigerator facilitates people's life, it is also prone to some problems caused by daily household use. It is common that the refrigerator door is forgotten to be closed, or the user leaves in a hurry when the refrigerator door is not fully closed

If this is done for a short period of time, the cooling effect of the refrigerator will not be good, and the outdoor water vapor will enter the box and form frost, which will bring about no change to the user. If the user does not close the refrigerator door for a long time, it will cause the refrigerator to compress The machine keeps working, which increases power consumption, and the cooling effect is not good. In severe cases, it will affect the life of refrigerator compressors and other components, and the compressor continues to work, resulting in continuous heat dissipation, which may cause dampness on the wall, resulting in peeling of the wall and breeding of insects. Wait

[0003] China Patent Publication No. 201680667U discloses a refrigerator door not closed reminder device. This patent uses a traditional circuit without a sensor for door sensing, and the accuracy is relatively poor.

And the operation after the recognition is simple to notify the user through the music box, and it is impossible to intelligently control the opening and closing of the refrigerator door
