Description

Vacuum fresh-keeping device and refrigerator

Technical Field

The invention belongs to the technical field of household appliances, and particularly relates to a vacuum refreshing device and a refrigerator.

Background

With the improvement of living standard, the refrigerator becomes a tool for storing food for thousands of households. The temperature of foods stored in the refrigerating chamber of the refrigerator is 2-8 ℃, and in the environment, some bacteria still grow and propagate to cause the spoilage of the foods and the long-term storage of the foods cannot be realized. Although the low temperature of the freezing chamber can inhibit most bacteria, the freezing process can damage the cellular structure of the food, causing nutrient loss. Meanwhile, the loss of mouthfeel of the food is also severe due to the dry consumption of the food under the freezing condition. Therefore, the vacuum preservation technology is produced at the same time. The vacuum fresh-keeping is mainly to make the air in the sealed space become thin and the oxygen content is reduced to the requirement that only the minimum of metabolic articles can be maintained. Thus, a range of consumption and changes in the production of food products having metabolic activity due to respiratory metabolism during storage can be minimized. And the growth and reproduction of aerobic microorganisms are also inhibited, so that the freshness of the food is maintained. Meanwhile, in the air exhaust process, volatile smell in the food and waste gas accumulation caused by anoxic respiration can be discharged from the sealed space along with air, so that the positive effect of keeping the quality of the food is achieved. The vacuum pumping process also helps to quickly cool down, so that the food can quickly reach the storage temperature.

Most of the existing refrigerator vacuum preservation technologies are that containers such as drawers and sealed boxes are vacuumized (such schemes are disclosed in chinese patent document with publication number CN 203011058U), and the pressure locking and maintaining capability of the existing refrigerator vacuum preservation technologies has great difficulty for structural designers. Meanwhile, because the drawer and the sealing box have fixed shapes, the pressure strength which can be borne by the materials is limited, and therefore the oxygen content in the storage space cannot be almost emptied like a self-locking sealing bag. In addition, the drawer and the sealing box are used as storage containers, so that the placement position of food is limited, certain requirements are imposed on the shape of the food, and large food or irregular food cannot be smoothly placed into the drawer or the sealing box, so that the limitation is quite large.
