Electromagnetic-control-based automatic closing device for refrigerators

Abstract

The invention provides an electromagnetic-control-based automatic closing device for refrigerators, and relates to the technical field of household appliances. The electromagnetic-control-based automatic closing device for the refrigerators comprises a box body, the inner wall of the right side of the box body is fixedly connected with an electromagnet I, the inner wall of the box body is movablyconnected with a sleeve rod, the inner wall of the bottom of the sleeve rod is fixedly connected with an electromagnet II, the bottom wall of inside of the sleeve rod is fixedly connected with a spring I, and the top of the spring I is fixedly connected with a movable electric block. According to the electromagnetic-control-based automatic closing device for the refrigerators, through cooperativeuse of the electromagnet I and the electromagnet II, when a door body is opened, the movable electric block is electrically connected to a conductive block, at the moment, the electromagnetic II is inthe energized state and produce magnetism same as that of the left side of a magnetic plate, the magnetic plate receives the repulsive force and drives a movable rod to contract to the inner side ofthe sleeve rod, and the magnetism on the right side of the magnetic plate is opposite to the magnetism on the left side of the electromagnetic I, the magnetic plate is attracted to the top, the effectof automatically closing the door is achieved, it is effectively guaranteed that the box door is in a closed state, and the service life of the refrigerator is prolonged.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an automatic closing device for refrigerators based on electromagnetic control. Background technique [0002] Household appliances are electrical equipment that people often use in daily life, such as electric kettles, refrigerators, and washing machines. Most of the refrigerators are open and close, similar to the principle of opening the door. When you need to take the food in the refrigerator , You need to open the refrigerator door before you can take out the ingredients inside. [0003] During the use of the current refrigerators, it is often the case that the refrigerator door is forgotten to be closed, and the current refrigerator door does not have an automatic closing device, so that the refrigerator door will not be automatically closed, causing the cold air in the refrigerator to leak and the temperature to rise, resulting in the failure of the refrigerato...
