Refrigerating and freezing device with air-regulating fresh-keeping function

Abstract

The invention provides a refrigerating and freezing device with an air-regulating fresh-keeping function. The device includes: a box, wherein the inner portion of the box defines a storage space and an enclosed air-regulating fresh-keeping subspace is formed in the storage space; an air-regulating fresh-keeping system, which includes an air-regulating membrane assembly and an aspirator pump, wherein the aspirator pump is configured to make the gas in the air-regulating fresh-keeping subspace permeate through the air-regulating membrane assembly, so that a gas atmosphere that is favorable for food preservation is formed in the air-regulating fresh-keeping subspace of the storage space; a refrigeration system, which is configured to supply cold energy to the air-regulating fresh-keeping subspace; a man-machine interactive system, which is configured to obtain an external operation and determine an air-regulating fresh-keeping index and a temperature index of the air-regulating fresh-keeping subspace according to the external operation; a controller, which is connected with the man-machine interactive system and configured to control the air-regulating fresh-keeping system and the refrigeration system according to the air-regulating fresh-keeping index and the temperature index. Therefore, the device can obtain external settings by the adoption of the friendly man-machine interactive system, and the corresponding air-regulating fresh-keeping control and refrigeration control are carried out.

Description

technical field [0001] The invention relates to the technical field of storage, in particular to a refrigeration and freezing device with the function of controlled atmosphere freshness preservation. Background technique [0002] Food is the source of energy for people's survival and is very important to people. For food storage, the two main aspects are heat preservation and freshness preservation. Generally speaking, temperature has a significant impact on the microbial activity on food and the action of enzymes in food. The decrease in temperature will delay the deterioration of food, and the refrigerator is to keep it constant. A low-temperature refrigeration device is also a civilian product that keeps food or other items in a constant low temperature and cold state. [0003] With the improvement of the quality of life, consumers have higher and higher requirements for the preservation of stored food, especially for the color and taste of food. Therefore, the stored f...

Problems solved by technology

[0005] The vacuum storage room is used to keep fresh. Since the box body is a rigid structure, it must be kept in a vacuum state. The requirements for the vacuum system and the sealing performance of the refrigerator are very high. There is a lot of air, which consumes a lot of energy for the refrigerator

[0006] Moreover, vacuum preservation cannot meet the storage requirements of all foods, and cannot meet the differentiated needs of users for fresh food storage. Users cannot personalize the conditions of the storage environment according to their own needs, thereby reducing the user experience.
