Refrigerator

Abstract

The invention relates to a refrigerator. The refrigerator extends the expiration date of food by five times or above than a common refrigerator. The refrigerator comprises a refrigerator shell, a refrigerator door, a cold storage chamber and a high-low pressure pressing device, wherein the cold storage chambers of various refrigerating devices such as the refrigerator achieve the purpose of fresh-keeping food and odor removal through reducing the activity of microbes at the low oxygen, low air pressure gas or fluid and low temperature environment which is lower than the lower pressure of the atmospheric ambient pressure; or the cold storage chambers of various refrigeration equipment such as the refrigerator process and pickle the food and retain freshness of the food in a manner of high air pressure infiltration at the high air pressure and low temperature environment higher than the atmospheric air pressure; and high air pressure and normal pressure or normal pressure and low air pressure, or low air pressure and high air pressure circulation change are adopted by the cold storage chambers of the various refrigeration equipment such as the refrigerator to discharge mycete and peculiar smell bacteria or other harmful components, the high-pressure pickling can shorten the processing time, the nutrient loss is avoided, and the harm of food deterioration to human health is prevented.

Description

Technical field: [0001] The invention relates to a refrigerator, which is used for food cleaning. Background technique: [0002] At present, people use refrigerators to preserve food, but when the food is too late to eat, it will often deteriorate after being stored for a long time. Survival, or some bacteria can not only survive at normal temperature but also adapt to low temperature environment, so they can still cause people to get sick due to food spoilage, and sometimes endanger people's lives. Invention content: [0003] The present invention is proposed in view of the above-mentioned problems, and aims to provide a safe refrigerator, which pumps germs into the atmosphere by creating a low-pressure and low-temperature environment, deprives bacteria of oxygen for survival, and makes bacteria It cannot survive due to lack of oxygen at low temperature, or it can be sterilized by filling carbon dioxide sterilizing gas to prevent food from deteriorating, and at the same ...

Problems solved by technology

[0002] At present, people use refrigerators to preserve food, but when the food is too late to eat, it will often deteriorate after being stored for a long time. Survival, or some bacteria can survive at room temperature and adapt to low temperature environment, so it will still cause people to get sick due to food spoilage, sometimes endangering people's lives
