Problems solved by technology

[0004] 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. More air, more energy consumption
Moreover, in a vacuum environment, it is difficult for food to receive cold, which is not conducive to food storage.
In addition, due to the vacuum environment, the user needs to spend a lot of effort to open the refrigerator door every time, which causes inconvenience to the user.
Although some refrigerators can ventilate the vacuum storage room through the vacuum system, this will cause the user to wait for a long time, and the timeliness is poor
A longer vacuum time will also cause serious deformation of the refrigerator box, that is, the existing refrigerators with a vacuum pumping structure cannot complete vacuum preservation well, and the strength of the box is required to be very high. The realization requirements are high and the cost is high.

Abstract

A refrigerating and freezing device comprises a storage space (211), an air regulating film assembly (30), an oxygen discharging pipeline (50), an air extracting device (40), and an anti-condensation device (50). In the refrigerating and freezing device, an atmosphere rich in nitrogen and poor in oxygen can be formed in the storage space (211), and condensation can be avoided on a side casing and a back plate.

Description

technical field [0001] The invention relates to the technical field of refrigerator storage, in particular to a refrigeration and freezing device. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. 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 food should also ensure that the color, taste, and freshness of the food remain unchanged as much as possible during the storage period. At present, in order to better store food in the market, there is only one kind of vacuum preservation. Vacuum fresh-keeping methods that are often used are vacuum bag fresh-keeping and vacuum storage compartment fresh-keeping. [0003] Using vacuum bags to keep fresh, consumers nee...
