Refrigerator door sealing device, refrigerator door and refrigerator

Abstract

The invention relates to a refrigerator door sealing device, a refrigerator door and a refrigerator. The refrigerator door sealing device comprises an annular sealing strip which is made of elastic airtight material and provided with at least one first air chamber, an inflation and deflation part which is communicated with the first air chamber of the annular sealing strip and used for inflating or deflating the first air chamber, and a control part which is connected with the inflation and deflation part in an operative mode and used for controlling the inflation and deflation part to inflate or deflate the first air chamber. Through the annular sealing strip which can be inflated or deflated in the use process, the refrigerator door of the refrigerator and a refrigerator body can be fully sealed, hot air can be prevented from entering a refrigeration chamber and / or cold air can be prevented from being leaked out of the refrigeration chamber, thermal insulation performance of the refrigerator can be greatly improved, and energy consumption can be lowered.

Description

technical field [0001] The invention relates to a refrigerator door sealing device, a refrigerator door including the sealing device, and a refrigerator including the refrigerator door. Background technique [0002] figure 1 A schematic cross-sectional view of a prior art refrigerator is shown. like figure 1 As shown, a refrigerator 1 includes a box body 2 and a door body 3, and there is a storage room 4 therebetween, such as a refrigerator room or a freezer room, for storing items. The door body 3 is provided with a door seal 5 , and the door body 3 is sealingly engaged with the box body 2 through the door seal 5 . Between the outer box and the inner box of the box body 2 and between the door panel and the door liner of the door body 3, there is a foam layer, such as rigid polyurethane foam (PUF), which has very good heat insulation performance. Usually, the door seal 5 is made of plastic, and compared with the foam layer in the box body 2 and the door body 3, the heat...

AI Technical Summary

Problems solved by technology

Therefore, traditional refrigerators have disadvantages such as large energy consumption, and the temperature in the storage room varies with the ambient temperature.
