Problems solved by technology

[0006] However, the traditional nitrogen-generating equipment used for controlled atmosphere fresh-keeping is bulky and expensive, so that this technology is basically limited to use in various large-scale professional storage warehouses (the storage capacity is generally at least 30 tons), and it is not suitable for family or individual user

Abstract

The invention provides a refrigerator. The refrigerator comprises a box body, a gas adjusting membrane assembly and a gas sucking pump assembly. A storing space and a compressor cabin are defined inside the box body. A storing container is arranged in the storing space, and a refreshment space is defined inside the storing container. The gas adjusting membrane assembly is arranged in the way that oxygen in airflow of a surrounding space of the gas adjusting membrane assembly can more penetrate through a gas adjusting membrane to enter an oxygen-enriched gas collecting cavity relative to nitrogen in the airflow. The inlet end of the gas sucking pump assembly communicates with the oxygen-enriched gas collecting cavity in a controlled mode through a pipeline and a pipeline switching mechanism, so that gas in the oxygen-enriched gas collecting cavity is pumped to the outside of the refreshment space, and the actual nitrogen content in the refreshment space is within the range of 81% to 98%. According to the refrigerator disclosed by the invention, the actual nitrogen content in the refreshment space is within a proper range, and aerobic respiration strength of a food material can be effectively lowered; and meanwhile, a basic respiration effect is guaranteed, anaerobic respiration of the food material is avoided, and therefore the storage effect of the food material is improved and the refreshing time of the food material is prolonged.

Description

technical field [0001] The invention relates to the field of item storage, in particular to a refrigerator. Background technique [0002] With the development of society and the improvement of people's living standards, and the faster and faster pace of people's life, people often buy a large number of items and place them in various refrigerators, but for leafy vegetables and fruits and vegetables, the storage of refrigerators The low temperature in the space will not only wrinkle and stain the skin of these foods, but also affect their original taste and nutrition. [0003] In the fresh-keeping technology of the refrigerator, oxygen is closely related to the oxidation and respiration of the food in the refrigerator. The slower the respiration of the food, the lower the oxidation of the food and the longer the preservation time. Reducing the oxygen content in the air has an obvious effect on food preservation. At present, in order to reduce the oxygen content in the refr...
