Embodiment 1

[0052] refer to Figure 9 , Figure 10 and Figure 11 , the chamber of the modified atmosphere membrane 410 is arranged on the shell 330, and the chamber of the modified atmosphere membrane 410 communicates with the storage device 300, and the chamber of the modified atmosphere membrane 410 is coated on the communication port between the chamber of the modified atmosphere membrane 410 and the storage device 300. The membrane 410 is configured such that oxygen in the storage device 300 permeates the atmosphere membrane 410 more than nitrogen into the chamber of the atmosphere membrane 410, forming an oxygen-enriched space in the chamber of the atmosphere membrane 410, and the atmosphere membrane 410 accommodates The cavity is connected with a vacuum tube 510, and the other end of the vacuum tube 510 is connected with a vacuum pump 500. The vacuum pump 500 is used to extract the gas in the oxygen-enriched space. Oxygen in the space of the external storage device 300 continuous...

Abstract

The invention relates to the technical field of refrigerator preservation, and discloses a refrigerator which comprises a low-temperature storage chamber and a door body for opening or closing the storage chamber and further comprises a storage device, an air adjusting film assembly and a vacuum pump; the air adjusting film assembly is arranged in the storage device and comprises an air adjusting film and an air adjusting film containing cavity; the air adjusting film containing cavity is formed in the storage device, and the air adjusting film containing cavity communicates with the storage device; an air adjusting film wraps a communicating opening of the air adjusting film containing cavity and the storage device; the vacuum pump communicates with the air adjusting film containing cavity through a vacuum pipe and is used for extracting gas in the air adjusting film containing cavity. The air adjusting film containing cavity is vacuumized through the vacuum pump, and the pressure in the air adjusting film containing cavity is reduced; at the moment, more oxygen in the storage device penetrates through the air adjusting film to enter the air adjusting film containing cavity compared with nitrogen, and then the oxygen is pumped and discharged by the vacuum pump, so that a nitrogen-rich and oxygen-poor gas atmosphere beneficial to food preservation can be formed in the inner space of the storage device, and the purpose of long-term preservation of fruits and vegetables is achieved.

Description

technical field [0001] The invention relates to the technical field of refrigerator preservation, in particular to a refrigerator. Background technique [0002] Normal air composition includes about 78% nitrogen, about 21% oxygen, about 0.939% rare gas, 0.031% carbon dioxide, and 0.03% other gases and impurities. Oxidation and respiration are closely related. The slower the respiration of food, the lower its oxidation and the longer the preservation time. Reducing the oxygen content in the storage space has a significant effect on food preservation. Therefore, controlled atmosphere preservation Technology has gradually become an important means of keeping food fresh. Modified atmosphere preservation technology generally refers to extending the storage life of food by adjusting the gas atmosphere (gas composition ratio or gas pressure) in the closed space where the storage is located. The basic principle of technology is: in a certain closed space, through various adjustment...
