Embodiment Construction

[0047] figure 1is a schematic perspective view of a refrigerator-freezer 100 according to an embodiment of the present invention. The refrigerating and freezing device 100 includes commonly known refrigerators, freezers, and other equipment with refrigeration preservation functions. The refrigerating and freezing device 100 may include an outer shell 10 , an inner container disposed in the outer shell 10 , and an insulating material filled between the outer shell 10 and the inner container. An overfreezing compartment 12 for storing food 60 to be frozen is defined in the inner container. A superfreezing door 22 for opening or closing the superfreezing compartment 12 is provided at the front opening of the superfreezing compartment 12 .

[0048] exist figure 1 In the illustrated embodiment, the refrigerating and freezing device 100 is a three-door refrigerator, and the inner tank further defines a refrigerating compartment 11 located above the over-frozen compartment 12 and ...

Abstract

The invention provides a cold preservation refrigeration device and a refrigeration method thereof. The cold preservation refrigeration device comprises a liner, a refrigeration system and a magnetic field generator. A super refrigeration room for storing food to be refrigerated is limited inside the liner. The refrigeration system is configured to provide cooling capacity for the super refrigeration room in a controlled mode, reduce and maintain the temperature of the food to be refrigerated to be a first preset temperature and first preset time, and then the temperature of the food to be refrigerated is lowered to a preset storage temperature of the food to be refrigerated. The magnetic field generator is used for providing a uniform magnetic field for the super refrigeration room and configured in the mode that when the time of the temperature of the food to be refrigerated maintained at the first preset temperature reaches the first preset time, the magnetic field generator is started, so that the food to be refrigerated enters a supercooling state under the effect of the magnetic field; and after a second preset time is started, the magnetic field generator is shut down, so that the food to be refrigerated gets rid of the supercooling state, the temperature of the food to be refrigerated is quickly reduced below the maximum ice crystal generation zone of the food to be refrigerated, the cell integrity in the process of food refrigeration is better preserved, and the refrigeration quality of the food is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration and freezing device and a freezing method thereof. Background technique [0002] During the use of the refrigerator, most users keep a lot of meat in the freezer, but the color of the frozen meat is dull, the thawing juice is lost, and the taste of the frozen meat is poor, which affects the user experience of the refrigerator. At present, there are mainly two schemes to achieve high-quality freezing in refrigerators on the market. One is to achieve rapid freezing and preservation of food through strong wind cooling or replacing the heat transfer medium; the other is to achieve supercooling and freezing by making the food enter a supercooled state. The quick-freezing method can effectively improve the quality of food freezing, but it still crystallizes from the outside to the inside when it freezes, and it cannot completely avoid the disadvantages o...
