Cold storage refrigerating device

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...

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...
