Vacuumizing device for refrigerator storage box and refrigerator

Abstract

The invention provides a vacuumizing device for a refrigerator storage box. The vacuumizing device comprises a machine box, a base and a supporting plate. The machine box is connected with the upper portion of the supporting plate. The base is connected to the lower portion of the supporting plate. The machine box is internally provided with a controller, a transmission device and a vacuumizing device body. The transmission device and the vacuumizing device body are both electrically connected with the controller. Under the control of the controller, the transmission device is used for connecting or disconnecting the vacuumizing device body and the storage box to be vacuumized, and the vacuumizing device body is used for vacuumizing the storage box. The invention further provides a refrigerator. According to the vacuumizing device for the refrigerator storage box and the refrigerator, the overall structure is simple, and vacuumizing process automation is achieved; the vacuumized storage box is placed at a low temperature to enable food to be in a specific negative pressure state, so that breeding of aerobic bacteria is effectively restrained, food oxidation is delayed, mildewing and spoilage are prevented, and the loss of vitamins is reduced.

Description

technical field [0001] The invention relates to a refrigerator fresh-keeping vacuum device, in particular to a refrigerator storage box vacuum device and a refrigerator. Background technique [0002] Because the refrigerator stores food in an atmospheric pressure environment, it is not closed, and it is easy to breed bacteria and cause food spoilage. In order to expand the fresh-keeping function of the refrigerator, a vacuum device for the fresh-keeping container is added on the basis of the original refrigerator function. The freezer compartment of the refrigerator occupies a large space, and since the vacuum fresh-keeping device is fixed in the box, it cannot be moved, and it is difficult to deal with future failures. At present, there are still vacuum fresh-keeping drawers, which need to extract the internal air when keeping fresh. Generally, the drawer and the cover are difficult to seal, and because the shape of the drawer is generally in a flat structure, it is difficu...

[0002] Because the refrigerator stores food in an atmospheric pressure environment, it is not closed, and it is easy to breed bacteria and cause food spoilage. In order to expand the fresh-keeping function of the refrigerator, a vacuum device for the fresh-keeping container is added on the basis of the original refrigerator function. The freezer room of the refrigerator occupies a large space, and because the vacuum fresh-keeping device is fixed in the box, it cannot be moved, and it is difficult to deal with future faults

At present, there are still vacuum fresh-keeping drawers, which need to extract the internal air when keeping fresh. Generally, the drawer and the cover are difficult to seal, and because the shape of the drawer is generally in a flat structure, it is difficult to withstand a low negative pressure value. Negative pressure fresh-keeping effect in the sense, due to the limitation of the function of the fresh-keeping drawer, the fresh-keeping effect is not ideal
