Moreover, the first fin 500 can extend forward from the front edge of the outer surface of the side of the support cavity wall 230 away from the center of the door body, so that the outer side surface of the door seal 10 can form an integral surface structure, which not only raises the door The appearance of the outer side of the seal 10 can also prevent it from being contaminated and contaminated.

In some embodiments, the door seal 10 can also include at least one support wall 700, each of which can be disposed within the support cavity 240 that can extend forwardly from the front surface of the containment cavity wall 210 to the support cavity wall 230. For example, the support wall 700 can be one that can be disposed in the middle of the support cavity 240.

In some embodiments, the first balloon wall 250 can include a first segment, a second segment, and a third segment. Specifically, the first segment may extend forward from the front edge of the outer surface of the side of the support cavity wall 230 toward the center of the door body and toward the center of the door body. The second section may extend rearward from the rear surface of the connecting wall 100 and away from the center of the door body, and its end is closer to the center of the door body than the end of the first section. The third segment connects the end of the first segment and the end of the second segment. Such a polygonal line structure can increase the stretching ratio of the door seal 10, so that the door seal 10 can be tightly fitted between the door body and the box body, thereby improving the sealing property of the refrigerator. Preferably, the angle between the first segment and the rear surface of the connecting wall 100 may be 50° to 70°, and the angle between the second segment and the rear surface of the connecting wall 100 may be 50° to 70°, and the second segment is Length of the third paragraph The ratio of degrees may be from 0.8 to 1.2, and the ratio of the length of the third segment to the length of the first segment may be from 1.3 to 1.6 to optimize the structure of the first airbag wall 250 as much as possible and to increase its draw ratio.

The second airbag wall 260 can include a fourth segment, a first arcuate connecting segment, a fifth segment, and a second arcuate connecting segment. Specifically, the fourth segment can be from a side of the receiving cavity wall 210 that faces the center of the door body. The rear edge of the outer surface extends toward the center of the door body, and the first arcuate connecting section may extend from the end of the first section toward the inner side of the casing and extend forward, and the fifth section may be from the end of the first curved connecting section Extending forwardly, the second curved connecting section may extend from the end of the second section to a direction away from the center of the door body to an end of the connecting wall 100 facing the center of the door body, that is, the second airbag wall 260 may be formed to face the refrigerator The protrusion in the middle direction of the storage compartment can make the second airbag wall 260 fit on the wall surface of the box without gaps when the door body is closed, and can isolate the cold air inside the box, thereby avoiding convection. Preferably, a support rib may be disposed on the outer surface of the second airbag wall 260 adjacent to the connecting wall 100 to block the cooling amount from flowing out of the gap between the door seal 10 and the door body, thereby improving the sealing performance of the refrigerator.

In some preferred embodiments, the door seal 10 can further include at least one airbag cavity dividing wall 800 disposed within the airbag cavity 270 and configured to partition the airbag cavity 270 into at least two sub-balloon cavities to support the receiving cavity 220, and The first airbag wall 250 can be assisted in increasing the draw ratio of the door seal 10. Preferably, the airbag partition wall 800 may be one that extends from the front edge of the outer surface of the accommodating chamber wall 210 toward the central side of the door body toward the center of the door body, and then extends toward the middle of the refrigerator storage space, and then forward and It extends away from the center of the door body, and finally extends forward and is attached to the rear surface of the connecting wall 100, and can be formed with a projection toward the central portion of the storage compartment of the refrigerator.

In some embodiments, as shown in FIG. 1 , the plug portion 300 can include an inner hollow mounting portion 320 and a hook portion 310 disposed at a bottom end of the mounting portion 320 . The hollow shape may be an inverted triangle, and the hook portion 310 may include a pair of hooks disposed opposite to each other along the center line of the plug portion 300, and the hook may extend obliquely rearward to firmly insert the door seal On the inside of the door. Preferably, the end of the insertion portion 300 may be provided with an abutting piece 311, and the abutting piece 311 may be arranged in a curved shape to abut against the inner wall of the receiving groove formed by the door body when the door body is closed, thereby inserting the insertion portion The gap between the 300 and the inner wall of the receiving groove is blocked, which further improves the sealing performance of the refrigerator.

In some embodiments, the door seal 10 is made of a TPR material, a PVC+TPU alloy material, or a TPE material. The door seal 10 can be effectively prevented from becoming hard due to long-term low temperature environment, and the elasticity is deteriorated, thereby improving the performance of the door seal 10, so that the door seal 10 can rebound freely even in an environment of about minus 18 degrees.

To this end, those skilled in the art will recognize that although the invention has been shown and described in detail herein Many other variations and modifications of the principles of the present invention can be directly determined or derived from the present disclosure without departing from the spirit and scope of the invention. Therefore, the scope of the invention should be understood and construed as covering all such other modifications or modifications.
