Abstract

The invention relates to the technical field of fresh-keeping refrigerators, in particular to a refrigerator with a variable temperature chamber having a nitrogen fresh-keeping function. The refrigerator comprises the variable temperature chamber, a gas separator, an air extracting pump, an air extracting pipe, a first air outlet pipe and a second air outlet pipe, a first joint and a second joint are formed in the variable temperature chamber, the air extracting pipe is connected with the first joint and the air extracting pump, the first air outlet pipe is connected with the air extracting pump and the gas separator, and the second air outlet pipe is connected with the gas separator and the second joint. The air extracting pump is used for extracting air in the variable temperature chamber into the gas separator through the air extracting pipe and the first air outlet pipe, the gas separator delivers nitrogen-enriched gas into the variable temperature chamber through the second air outlet pipe, and oxygen-enriched gas is exhausted. Food can be preserved in the refrigerator for a long term, and the refrigerator is simple in integral structure, convenient to operate and high in practical applicability, and a pressure relief component can relieve pressure before the food is taken out.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping refrigerators, and more particularly relates to a refrigerator with nitrogen fresh-keeping function in a temperature-changing room. Background technique [0002] Refrigerators are the main appliance for end users to store food. With the improvement of living standards and the development of technology, people not only require food to be stored for a longer period of time, but also require food to maintain its original flavor to the greatest extent during storage. [0003] Refrigerator fresh-keeping technology can largely learn from cold storage for food storage and fresh-keeping technology. From the perspective of the technical development of cold storage, in 1851, the Australian James designed and manufactured the first small refrigeration compressor and auxiliary equipment to build a mechanical cold storage. In 1916, British scientists Kidd and West invented controlled atmosphere storage....
