Air-adjusting preservation storage device

Abstract

The invention provides an air-adjusting preservation storage device. The air-adjusting preservation storage device comprises a box body and an oxygen removal device, wherein a first storage space is defined in the box body, and the oxygen removal device is configured to extract part of or all oxygen in air in the first storage space from the first storage space so as to obtain a nitrogen-rich and oxygen-poor gas atmosphere facilitating food preservation in the first storage space. The air-adjusting preservation storage device provided by the invention can extract oxygen in the first storage space, and the nitrogen-rich and oxygen-poor gas atmosphere facilitating food preservation is formed in the first storage space. In the gas atmosphere, the strength of aerobic respiration of fruits and vegetables is reduced by reducing the content of oxygen in the fruit and vegetable storage space, and meanwhile, the basic breathing action is ensured, and anaerobic respiration of fruits and vegetables is prevented, so that a purpose of preserving the fruits and vegetables for a long time is achieved. The air-adjusting preservation storage device provided by the invention not only is good in preserving effect, but also is low in requirements on rigidity and strength of the box body and the like, low in implementation requirement and also low in cost.

Description

technical field [0001] The invention relates to the technical field of article preservation, in particular to a modified atmosphere preservation storage 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. The vacuum preservation methods that are often used are vacuum bag preservation and vacuum storage space preservation. [0003] Using vacuum bags to keep fresh, cons...

AI Technical Summary

Problems solved by technology

[0004] The vacuum storage space is used to keep fresh. Since the box body is a rigid structure, it must be kept in a vacuum state, which has high requirements for the vacuum system and the sealing performance of the refrigerator. More, 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 into the vacuum storage space 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.
