Door seal structure, refrigerator door body and refrigerator

Abstract

The invention provides a door seal structure, a refrigerator door body and a refrigerator. The door seal structure is arranged on the refrigerator door body and comprises a magnetic stripe bag, an auxiliary airbag, a main airbag and a mounting part, wherein the upper end surface of the auxiliary airbag is higher than the upper end surface of the magnetic stripe bag; the main airbag comprises a left support rib, a lower support rib and a right support rib which are connected successively; an included angle formed by the first rib strip and the second rib strip of the left support rib is an acute angle, and an included angle formed by the third rib strip and the fourth rib strip of the right support rib is an acute angle; the extension cord of the other end of the second rib strip intersects with the extension cord of the other end of the fourth rib strip to form an included angle and the included angle is an obtuse angle or a flat angle, and the extension cords of the first rib strip and the third rib strip intersect under the main airbag. According to the door seal structure, through the upper end surface of the auxiliary airbag, the sealing performance is improved, and the probability of freezing leakage is reduced; the extension cords of the other ends of the second rib strip and the fourth rib strip and the extension cords of the first rib strip and the third rib strip encircle a triangle or a similar triangle, and the magnetic stripe bag is not easily twisted when being drawn.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a door seal structure, a refrigerator door body and a refrigerator with the door seal structure. Background technique [0002] At present, after the existing refrigerator door seal structure is matched with the door body, the door seal has poor anti-deformation ability. After the middle beam of the refrigerator or the door body is sunken, the airbag of the door seal on the side of the hinge is easily distorted and deformed, and the position of the magnetic strip is shifted. Seals are prone to twisting, resulting in a small pressing area of ​​the magnetic strip, cold leakage and condensation in the refrigerator, reduced door seal life, and increased energy consumption; in addition, there is a gap between the door seal installation foot and the tank, which is easy to leak cold, Increased energy consumption and other issues, reducing customer satisfaction.
