Embodiment Construction

[0029] This embodiment firstly provides a door seal 100 for a refrigerator, figure 1 It is a schematic diagram of a cross-section of a door seal 100 according to an embodiment of the present invention, which includes: a rubber strip body 110 , an expansion head 120 , a mounting seat 130 and a support column 140 .

[0030] The strip body 110 defines a sealing air bag 111 extending along its length direction inside. The cross section of the main body of the strip body 110 is approximately rectangular, that is, the main body of the strip body 110 has four sides extending along its length direction. The above four sides include two relatively large and flat sides and two relatively small sides with multiple folds 150 . The surface of the strip body 110 also has an expansion head 120 protruding from one of its sides, and the inner space of the expansion head 120 communicates with the sealed air bag 111 . In this embodiment, the above-mentioned side on which the expansion head 120 ...

Abstract

The invention provides a door seal for a refrigerator and the refrigerator. The door seal comprises an adhesive tape body, an installation seat and a support column. A seal gasbag extending in the length direction of the adhesive tape body is limited in the adhesive tape body. The adhesive tape body is further provided with an expansion head extending out of one side face of the adhesive tape body. The inner space of the expansion head communicates with the seal gasbag. The seal gasbag can be inflated or can release gas so as to adjust the size of the expansion head. The door seal can be installed on a refrigerator door body, when the door body is closed by a user, due to supporting of the support column, the expansion head can enter a groove preset in a refrigerator body. The expansion size of the expansion head can be adjusted by controlling inflation and deflation of the seal gasbag. When the expansion head expands, the pressure of the gasbag wall of the expansion head and the pressure of the inner side wall of the groove are increased, meanwhile, friction force is increased, thus the door seal pulls the door body and the refrigerator body closely, the gap between the door body and the refrigerator body is eliminated, and the insulation effect of the refrigerator is improved.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a door seal for a refrigerator and the refrigerator. Background technique [0002] The door seals used in refrigerators currently on the market generally use magnetic strips to close the cabinets. However, after the refrigerator has been used for a long time, a gap will appear between the door seal and the cabinet due to weakening of the magnetic strip or deformation of the door seal. Once the door body is not tightly sealed, the cold air inside the refrigerator will leak out, which will affect the refrigeration of the refrigerator and food preservation. At the same time, the leakage of cold air will increase the burden on the refrigeration system of the refrigerator and waste electricity. [0003] In addition, the door seal will be compressed during the closing process of the existing refrigerator, and the air in the air bag may gradually leak, which may eventually cause the PVC or...
