A refrigerator sealing device and its control method

Abstract

The invention discloses a refrigerator sealing device and a control method thereof, and relates to the technical field of refrigerator sealing. The coil winding assembly is installed between the inner lining of the refrigerator and the metal side plate in the present invention; the coil winding assembly includes a wire, a magnetic core and a connector; Wire coil; the coil winding assembly is embedded in the refrigerator lining to form a closed and complete magnetic field; door seal magnetic strip is installed on one side of the door seal; the door seal corresponds to the coil winding assembly on the refrigerator lining; the coil winding assembly is in contact with the door seal magnetic strip Adsorption; the wire is connected with the main control unit of the refrigerator. The invention installs the coil winding assembly between the inner lining of the refrigerator and the metal side plate, and the wire of the coil winding assembly is connected to the main control unit of the refrigerator; the magnetic control of the coil winding assembly is realized, and then the magnetic strip of the door seal is adsorbed to the coil winding assembly control, so as to conveniently control the sealing of the box body and the door body, which is convenient and practical.

Description

technical field [0001] The invention belongs to the technical field of refrigerator sealing, and in particular relates to a refrigerator sealing device and a control method thereof. Background technique [0002] In the prior art, the door seal is an important part affecting the performance of the refrigerator; the refrigerator box and the door body are sealed and connected by the refrigerator door seal. The refrigerator door seal is a sealing plastic strip made of PVC or TPE soft material and permanent magnetic strip. The sealing condition of the refrigerator door seal directly affects the exchange of cold and hot gas inside and outside the refrigerator box. The humid and hot air outside the box enters the box through the door seal, and is cooled by the evaporator. The water vapor brought in by it condenses into frost on the evaporator, and the air-cooled refrigerator uses the built-in defrosting heater to heat and melt the frost layer. It can be seen that the sealing of t...

Problems solved by technology

[0003] After the existing door seal is used for a long time, the magnetism of the magnetic strip of the door seal will be reduced, and the door seal itself will harden when it is exposed to low temperature for a long time, which will easily lead to the lax closing of the door body, so that more hot air will enter the box , a large amount of ice and frost in the heat conduction refrigerator will increase the energy consumption of the refrigerator

At the same time, users have a certain degree of randomness in opening and closing the door. The existing door seal is magnetically fixed. If the door body is not closed properly, the refrigerator will be severely frosted and defrosted frequently. This situation is not easy to be discovered by users. If it continues to develop in the long run, Frequent defrosting may cause the water tray to overflow, affecting user experience
