[0021] Whether the terminal 4 is energized can be controlled by a switch, which is turned on to power on and turned off to power off. This is the prior art.

[0022] A further improvement of the technical solution is that an insulating sheath 5 is sleeved on the terminal 4 .

[0023] A further improvement of the technical solution is that an adhesive 6 is installed on the aluminum foil piece 1, and the adhesive 6 is used for bonding and adhering the aluminum foil piece 1. Therefore, the present application can be additionally added to a refrigerator without a defrosting function, and can be attached to the area of ​​the refrigerator that is prone to frost.

[0024] In an optional embodiment, the adhesive member 6 includes an adhesive layer 8 , the adhesive layer 8 is fixedly connected to the aluminum foil member 1 , and a release paper 7 is provided on a side of the adhesive layer 8 away from the aluminum foil member 1 .
