Description

Technical Field

[0001] The utility model relates to the field of refrigerator flip beams, in particular to a metal-etched flip beam film heater for refrigerators. Background Art

[0002] The refrigerator flip beam is widely used in double-door refrigerators. It can be simply understood as a beam that can rotate 90° in the vertical direction. The sheet metal on its surface seals with the magnetic strips on both sides of the refrigerator door to form a relatively closed space between the box body and the door body to achieve the purpose of preserving cold air.

[0003] Usually, a refrigerator flip beam is set on the side wall of any door body. When closing the door, the user must advance the flip beam on the door body with the flip beam to a vertical state. When the door body is closed, the flip beam is guided to a horizontal state by the guide structure of the guide seat in the top of the refrigerator box to complete the closing.

[0004] When the two refrigerator doors are closed, one of the door bodies is attached to the surface of the flip beam. When the refrigerator is used for a long time, frost, ice and condensation may form at the connection between the refrigerator door and the flip beam, making it difficult to open the refrigerator door.

[0005] Therefore, it is necessary to provide a metal-etched flip beam film heater for a refrigerator to solve the above-mentioned technical problems. Utility Model Content
