Description

Food container used for nitrogen refrigerator

The present invention relates to a food storage container used in a nitrogen refrigerator, and more specifically, to store the food in a nitrogen refrigerator to prevent oxidation and deterioration of the food by oxygen, while injecting oxygen inside while effectively injecting nitrogen. The present invention relates to a food storage container used in a nitrogen refrigerator developed to easily discharge the containing air.

In general, the refrigerator is divided into a freezer compartment and a refrigerating compartment, which is essential for almost all households to preserve food at low temperature by blowing cold air from the evaporator into the freezer compartment and the refrigerating compartment by driving a fan installed at the rear of the freezer compartment. It can be called a home appliance.

In addition, this technology is applied to various ships, aircrafts, and automobiles to maintain the freshness of food in transporting goods at various logistics stages, or the low temperature storage has the effect of extending the shelf life, but due to oxygen in the air even at low temperatures. Due to the accelerated oxidation of stored foods, there was a limit to the long-term storage of stored foods. On the other hand, with the advancement of modern society, the complexation of home appliances used in homes is accelerating, and as the air pollution due to industrialization becomes serious, well-being (air purifier or oxygen generator) for better living environment ( The development and distribution of WELL-BEING products is on the rise.

However, until now, in the case of home appliances, air purifiers or oxygen generators, the manufacturers are divided according to the system of product development, and there is no complexation. In recent years, only the air conditioners and air purifiers of the same air conditioner series are combined. In the case of refrigerators and oxygen generators, proposals for complexation have not been made. Therefore, a user who wants to purchase an oxygen generator separately purchases a storage including a refrigerator and an oxygen generator or an air cleaner equipped with an oxygen generator, so that each product occupies a separate space by installing two devices. It has disadvantages in terms of space utilization.

Therefore, the present applicant inhales the outside air from the Korean Patent Application No. 10-2010-0101228 'Nitrogen Refrigerator', separates oxygen and nitrogen from the sucked air, and discharges all the separated oxygen into the indoor air purification. In addition to the effect, the separated nitrogen is introduced into the inside of the refrigerator to prevent oxidation of food stored in the food storage unit, thereby improving the air purification function in the room and preventing oxidation of the refrigerator. A nitrogen refrigerator was proposed.
