Matching component for freezer door seal and door liner

Abstract

The invention discloses a matching component for a freezer door seal and door liner. The matching component comprises a matching component body comprising a door seal connecting portion platform, protrude portions, a bending portion, a door seal slot, an opposite-directional bending portion and a door liner portion connecting portion slot. The door seal connecting portion platform is arranged at the upper end of the matching component body. The rest portion of the left end of the platform is firstly bended to the platform direction to form the bending portion. The door seal slot is arranged between the bending portion and the door seal connecting portion platform. The rest portion of the bending portion is bended upwards secondly, and is bended to the opposite direction of the direction of the first bending to be bended thirdly to form the opposite-directional bending portion. The door liner portion connecting portion slot is formed between the bending portion and the opposite-directional bending portion. Angles of three bending are all 90 degrees, and the three bending are in a flat 'Z' shape. At least one protrude portion is arranged in the middle or on the left portion of the door seal connecting portion platform. The door seal connecting portion platform, the protrude portions, the bending portion, the opposite-directional bending portion and the matching component body are integrated. The matching component has the advantages that mold manufacture is simple, stripping is easy, cost is low and sealing effect is good.

Description

technical field [0001] The invention relates to a matching component of a refrigerator door liner and a door seal. Background technique [0002] In the manufacturing process of refrigerators, because this type of product is different from other household appliances, it is necessary to set up a thermal insulation layer. Usually, manufacturers usually use the production method of separately producing the outer shell and the inner tank, and then assembling. This production method is suitable for flow operations. , The production efficiency is greatly improved. However, in the assembly process, there are often cases where the shell and the inner tank are not closely matched. The main reason is that the matching components are not scientific enough. For example: for the cooperation between the door seal and the door liner of the freezer, most of the freezers on the market currently use the following two matching components: Method 1, see figure 1 , in the figure (1) is the matc...

AI Technical Summary

Problems solved by technology

The disadvantage is that after the door seal and the door liner are assembled, it is necessary to fill the inner layer of the door liner with foaming agent. Under the pressure of thermal expansion, the door seal deviates away from the door liner, causing a gap between the door liner and the door liner. , Poor sealing, resulting in decreased thermal insulation performance, increased energy consumption, and easy entry of sundries to reduce product quality

Method 2, see figure 2 , (1) in the figure is the matching component of the door seal and the door liner, the door liner (2), the door seal (3), the barbed pawl (5) is also set on the matching component (1), the door liner (2) The Ω suction groove (4) is built in the connecting part of the joint, and the matching member (1) can tightly combine the door liner and the door seal, avoiding the possible problems of the first method, but the second method also has its disadvantages, that is, the door liner is built-in The Ω suction groove (4) and the barbed pawl (5) increase the difficulty of mold making and increase the product cost
