Embodiment Construction

[0051] 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.

[0052] 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 isolation bag, a first cord and a first motor, wherein the isolation bag is arranged in a storage compartment of the refrigerator and provided with a bag opening used for storing and taking objects; the first cord movably surrounds the periphery of the bag opening, and the bag opening can be fastened when the first cord is strained towards the winding end of the first cord; and the first motor is rotated towards a first direction in a controlled mode so that the first cord can be driven to be strained in the winding end of the first cord so as to fasten the bag opening. The invention further provides the quick-freezing method for the refrigerator. When the objects are quickly frozen through the quick-freezing method, on one hand, the objects can be protected against contamination or air-drying, and on the other hand, the bag opening of the isolation bag can be fastened automatically.

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...
