Embodiment Construction

[0058] 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.

[0059] 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 refrigerator. The refrigerator comprises an insulating bag which is arranged in a storage chamber of the refrigerator and used for storing articles and a plurality of closing units. Each closing unit comprises a first line cord and a first motor. The first line cords are arranged outside the insulating bag and can move around the insulating bag. The first motors are configured to be controlled to rotate in the first direction so as to drive the corresponding first line cords to be tightened towards the winding ends of the first line cords so that the insulating bag can be closed to one chamber wall of the storage chamber as the first cords are tightened. The invention further provides the quick-freezing method for the refrigerator. When the articles are quick-frozen by the adoption of the quick-freezing method, on the one hand, the articles can be protected against pollution or , and on the other hand, when the isolating bag is not used, the isolating bag can be closed into the chamber wall of the storage chamber through the closing units automatically, and the storage space of the storage chamber is not occupied.

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. If adopt the mode such as packing bag, fresh-keeping bag, then neither convenient nor safe. 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 con...
