Embodiment Construction

[0059] figure 1 is a schematic diagram of a refrigerator according to one embodiment of the present invention. see figure 1 , The refrigerator 100 of the embodiment of the present invention may include a storage compartment 20 and an insulation bag 70 disposed in the storage compartment 20 . The insulation bag 70 is used to store items. The insulation bag 70 may be made of a flexible material. In particular, a film layer formed of a food-grade material, such as a food-grade PE film layer, may be coated on the inner surface of the bag wall of the insulation bag 70 to ensure food safety.

[0060] In the embodiment of the present invention, the insulation bag 70 can be completely separated from the storage compartment 20 , that is, the insulation bag 70 can be taken out from the storage compartment 20 . In some embodiments, the insulation bag 70 is partially detachably installed on the wall of the storage compartment 20, such as detachably installed on the circumferential wal...

Abstract

The invention provides a refrigerator and a quick freezing method for the same. The refrigerator comprises an isolation bag, wherein the isolation bag is arranged in a storage chamber of the refrigerator and is used for storing articles; a first magnetic material is arranged on at least part of the wall of the storage chamber; and a second magnetic material which attracts the first magnetic material is correspondingly arranged on at least part of the wall of the isolation bag, so that the wall, with the second magnetic material, of the isolation bag is magnetically attracted to the first magnetic material when approaching the wall, with the first magnetic material, of the storage chamber. The invention further provides the quick freezing method for the refrigerator. The isolation bag for storing the articles is arranged in the storage chamber of the refrigerator, so that the articles to be cooled can be protected against being polluted or air-dried. When not used, the isolation bag of the refrigerator can be magnetically attracted to the wall of the storage chamber, and does not occupy storage space of the storage chamber.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator and a quick-freezing method for the refrigerator. Background technique [0002] When freezing and refrigerating food, it is usually necessary to reduce the temperature of the food with the help of a heat transfer medium, such as an air-cooled refrigerator using cold air as a heat transfer medium, and a liquid quick-freezing compartment using quick-freezing liquid as a heat transfer medium. However, whether it is air cooling or liquid freezing, it may cause food contamination, and air cooling may also cause food to be air-dried. Contents of the invention [0003] An object of the present invention is to overcome at least one disadvantage of the prior art by providing a refrigerator provided with an insulating bag to prevent items to be cooled from being contaminated or dried out. [0004] A further object of the present invention is to provide a r...
