Embodiment Construction

[0068] 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 to be cooled, so that the items can be quickly frozen in the storage compartment 20 using the quick-freezing liquid 90 . The storage compartment 20 is configured to receive the quick-freezing liquid 90 injected therein in a controlled manner, so that at least a part of the items stored in the insulation bag 70 are submerged in the quick-freezing liquid 90 . 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. In addition, a film layer (or film ...

Abstract

The invention provides a refrigerator and a quick freezing method used for the refrigerator. The refrigerator comprises an isolation bag and an air extracting pump, wherein the isolation bag is arranged in a storage room and used for storing a to-be-cooled object, and the air extracting pump is configured to conduct air extracting on the isolation bag in a controlled mode so that the wall of the isolation bag can be attached to the outer surface of the object stored in the isolation bag in a collapsed mode. The storage room is configured to contain quick freezing liquid injected into the storage room in a controlled mode so that the object stored in the isolation bag is at least partially immersed in the quick freezing liquid. The invention further provides the quick freezing method used for the refrigerator. When the object is subjected to quick freezing through the quick freezing method, on the one hand, the object can be protected from being polluted or air-dried, on the other hand, the situation that quick freezing liquid heat transfer is affected by air is avoided, the large contact area of the object and the quick freezing liquid is ensured, and thus quick freezing is conducted on the object at a high freezing speed.

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 defect in the prior art, and provide a refrigerator which has a faster freezing speed while avoiding contamination of items by quick-freezing liquid. [0004] A further object of the present invention is to provide a refrigera...
