Definitions
- the invention relates to a refrigerating and freezing device with a nitrogen-preserving and fresh-keeping function, in particular to a refrigerator and a freezer with a M-preserving function.
- refrigerators and freezers are used to preserve fresh food. This method of refrigerating refrigerators and freezers is not ideal. For leafy vegetables and melons, low temperatures of zero degrees Celsius will make them lose their original taste. And nutrition, wrinkles and marks appear on the epidermis.
- all the refrigerators and freezers on the market, and the recently introduced o °c fresh-keeping refrigerators have the disadvantages of aging, fading, deformation, and the inability to keep fresh after a long power outage. It is difficult to solve the oxygen content in the refrigerator to promote food oxidation.
- Nitrogen is an inert, colorless, non-toxic, odorless gas that does not chemically react with food. It can effectively reduce the oxidative deterioration and decay of foods, thus keeping food fresh. Therefore, according to the principle of nitrogen preservation, a refrigerator and a freezer with nitrogen-preserving function will be created, which will bring people a new consumption concept in life, so that people can eat high-quality, nutritious fresh food. .
- the refrigerators and freezers with nitrogen-preserving functions disclosed in the prior art are merely a principle disclosure, and the technical solutions that must be solved when manufacturing products, such as: the combination of nitrogen-making equipment and refrigerators, freezers, Problems such as detection and control of nitrogen content have not been proposed in the prior art.
