Abstract

The invention relates to a door seal for a refrigeration and freezing device and the refrigeration and freezing device. The door seal includes a mounting portion for mounting the door seal on a door body of the refrigeration and freezing device and an air bag portion connected to the upper portion of the mounting portion and used for forming air-tight seal between the door body and a box body of the refrigeration and freezing device. The air bag portion is provided with two symmetric auxiliary air bags adjacently disposed above the mounting portion, two symmetric internal main air bags disposed above the two auxiliary air bags and two external main air bags performing embracing on the transverse outer sides of the two auxiliary air bags and the two internal main air bags. The refrigerationand freezing device includes the box body, the door body and the door seal, wherein the box body is provided with a storage space for storing articles; the door body is connected to the front side ofthe box body, so as to open and / or close at least part of the storage space; the door seal is mounted on the door body and configured to form air-tight seal between the door body and the box body when the door body is a closed state. The refrigeration and freezing device with the door seal is very low in cold leakage amount and good in sealing performance.

Description

technical field [0001] The invention relates to refrigerating and freezing technology, in particular to a door seal for a refrigerating and freezing device and a refrigerating and freezing device with the door seal. Background technique [0002] At present, the door seals used in most refrigerators to form an airtight seal between the refrigerator box and the refrigerator door include a mounting part, an air bag part and a magnetic strip disposed in the air bag part. The installation part is used to clamp with the door body, the airbag part is used to insulate the heat and elastically fill the gap between the doors, and the magnetic strip is used to attract the door body to the box body. Due to the good thermal conductivity of the magnetic strip, it is very easy to cause the loss of cooling capacity in the cabinet, which in turn will cause frost and dew at the front opening of the cabinet, and increase the energy consumption of the refrigerator. [0003] In order to avoid t...
