Chest freezer door seal and chest freezer

Abstract

The invention provides a horizontal refrigerator door seal and a horizontal refrigerator. The door seal is not prone to deforming, good in rebound resilience and reliable in sealing, reserved gaps are not prone to appearing on the periphery of a horizontal refrigerator door with the door seal, and the sealing and heat insulation effect is good. The horizontal refrigerator door seal comprises a mounting fixing part and a sealing part. The mounting fixing part and the sealing part are of an integrated structure, and the mounting fixing part is located above the sealing part. The sealing part is provided with a sealing air chamber. A supporting air chamber, a rebound air chamber and supporting ribs are arranged in the sealing air chamber. One end of each supporting rib is connected to the upper side face of the sealing air chamber, and the other end of each supporting rib is connected to the rebound air chamber. When the door is closed under the action of gravity to extrude a door seal strip, the supporting force of the door seal can be improved through the supporting air chamber, and the situation that the door seal excessively deforms due to the too heavy door is avoided; the rebound air chamber guarantees the rebound resilience of the door seal; and the supporting ribs achieve the supporting function and the rebound function, it is further guaranteed that the door seal keeps the basic shape within the deformation range, and the sealing and heat insulation effect of the door seal is good.

Description

technical field [0001] The invention relates to a structural part of a horizontal refrigerator, in particular to the improvement of the door seal structure of the horizontal refrigerator. Background technique [0002] The power consumption of the freezer is an important indicator to measure the performance of the freezer, which directly determines the energy efficiency level of the product, and is also an indicator that consumers pay special attention to. There are many factors that affect the power consumption of the refrigerator, and the sealing performance of the refrigerator door body is an important factor among them. In order to reduce cooling capacity consumption, reduce power consumption, and reduce expenses, it is an economical and direct method to improve the sealing performance of the door body. [0003] The freezer door seal is usually made of soft polyvinyl chloride, which is embedded between the freezer door and the box to play a role of sealing and heat insul...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned door seal structure has the following technical problems: when the door body using the above-mentioned door seal structure is closed, the airbag 2 is supported only by the second sub-airbag 22, and the rebound of the airbag 2 is realized only by the first sub-airbag 21, causing the door seal to be easily damaged. Deformation and poor resilience, long-term use of the door seal is not easy to return to its original shape, and it will also cause the wings or laps on both sides of the airbag to deform easily, causing flash cracks around the door body, and poor sealing and heat insulation effect
