Cold storage and refrigerating device with air adjustment refreshing function

Abstract

The invention provides a cold storage and refrigerating device with the air adjustment refreshing function. The cold storage and refrigerating device comprises a box body, an air adjustment refreshing system and a working condition detection system. A storing space is defined inside the box body, and an airtight air adjustment refreshing subspace is formed in the storing space. The air adjustment refreshing system comprises an air adjustment membrane component and an air extracting pump. The air extracting pump is arranged in the way that gas in the air adjustment refreshing subspace is permeated through the air adjustment membrane component so that a gas atmosphere facilitating food preservation can be formed in the air adjustment refreshing subspace of the storing space. The working condition detection system is arranged to detect the working state of the air adjustment membrane component and the air extracting pump and to output prompt information when the working state is abnormal. According to the cold storage and refrigerating device, the air adjustment refreshing system is high in working reliability, and the refreshing degree of food stored in the air adjustment refreshing subspace can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of storage, in particular to a refrigeration and freezing device with the function of controlled atmosphere freshness preservation. Background technique [0002] Food is the source of energy for people's survival and is very important to people. For food storage, the two main aspects are heat preservation and freshness preservation. Generally speaking, temperature has a significant impact on the microbial activity on food and the action of enzymes in food. The decrease in temperature will delay the deterioration of food, and the refrigerator is to keep it constant. A low-temperature refrigeration device is also a civilian product that keeps food or other items in a constant low temperature and cold state. [0003] With the improvement of the quality of life, consumers have higher and higher requirements for the preservation of stored food, especially for the color and taste of food. Therefore, the stored f...

Problems solved by technology

[0005] The vacuum storage room is used to keep fresh. Since the box body is a rigid structure, it must be kept in a vacuum state. The requirements for the vacuum system and the sealing performance of the refrigerator are very high. There is a lot of air, which consumes a lot of energy for the refrigerator

Due to the high requirements for the above-mentioned vacuum fresh-keeping storage compartment, the reliability is low, and it is easy to be damaged, which brings great inconvenience to the user.
