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.
[0005] In addition, the inventors found that: due to the large volume and high cost of nitrogen-making equipment traditionally used for controlled atmosphere preservation, this technology is basically still limited to use in various large-scale professional storage warehouses (storage capacity is generally at least 30 tons or more) )
It can be said that what kind of appropriate gas adjustment technology and corresponding devices can be used to economically miniaturize and quiet the air conditioning system, making it suitable for families or individual users, is a problem that technicians in the field of air conditioning and fresh-keeping have been eager to solve but have never been able to solve. Technical problems that can be successfully solved

Embodiment Construction

[0037] figure 1 is a schematic structural diagram of a refrigerating and freezing device according to an embodiment of the present invention, figure 2 yes figure 1 Schematic block diagram of another view of the structure shown. Such as figure 1 and figure 2 As shown, the embodiment of the present invention provides a refrigerating and freezing device, which may include a box body 20 , a main door body, a refrigeration system, an air-conditioning membrane assembly 30 , and an air extraction device 40 .

[0038] A first storage space 211 is defined in the box body 20 . For example, the box body 20 may include an inner container 21 defining a first storage space 211 therein. The main door body may be composed of two side-by-side doors, both of which are rotatably mounted on the box body 20 and configured to open or close the first storage space 211 defined by the box body 20 . Optionally, the main door body can also be one door body. Further, a storage container is provi...

Abstract

The invention provides a cold storage refrigerating device which comprises a cabinet body, an air adjusting film assembly and an air extractor. A first storage space is defined in the cabinet body. A storage container is arranged in the first storage space. The storage container is provided with a cylinder body and an air adjusting preserving space located in the cylinder body. The air adjusting film assembly is installed on the cylinder body, and space around the air adjusting film assembly communicates with the air adjusting preserving space. The air adjusting film assembly is provided with at least one air adjusting film and an oxygen enrichment gas collecting cavity and arranged to enable more oxygen in air flow in the space around the air adjusting film assembly to penetrate the air adjusting films relative to nitrogen in air flow in the space around the air adjusting film assembly to enter the oxygen enrichment gas collecting cavity. The air extractor communicates with the oxygen enrichment gas collecting cavity through a pipeline to extract and pump the gas penetrating into the oxygen enrichment gas collecting cavity out of the storage container. The cold storage refrigerating device is good in preserving effect, moreover, the requirements for rigidity and strength of the cabinet body and the like are low, the achievement requirement is low, and the cost is low. Moreover, the size is small, the noise is low, and cold storage refrigerating device is particularly applicable to families and individuals.

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...
