The invention provides a vacuum storage device and a refrigerator. The vacuum storage device comprises a shell, a cover body, a sealing piece arranged between the shell and the cover body, a vacuumizing assembly arranged on the shell or the cover body, a pressure relief assembly used for relieving pressure of a storage cavity and an adjusting assembly located on the shell or the cover body. The pressure relief assembly comprises a pressure relief hole communicating with the storage cavity, a sealing plug and a pressure relief piece; the sealing plug is provided with a sealing portion for sealing the pressure relief hole; and the pressure relief piece comprises a fixed seat and a pressure relief sliding block connected to the fixed seat in a sliding manner, the end, close to the sealing plug, of the pressure relief sliding block is provided with an insertion portion capable of enabling the sealing portion to open the pressure relief hole on the edge of the sealing portion, and the pressure relief piece and the pressure relief hole are both located on the cover body or the shell. The adjusting assembly drives the pressure relief sliding block to get close to or away from the sealing plug, the sealing part covers the pressure relief hole in the natural state and is not affected by external force, that is, the sealing portion can open the pressure relief hole to achieve pressure relief only after pressure relief is achieved and the adjusting assembly is operated, the structure is simple, and the sealing effect is good.
Description
technical field [0001] The invention relates to the field of refrigeration devices, in particular to a vacuum storage device and a refrigerator. Background technique [0002] In the existing fresh-keeping technology of the refrigerator, using a vacuum storage device (ie, a vacuum storage drawer) is the most effective way to realize the vacuum fresh-keeping technology of the refrigerator. The principle is to install an air extraction device in the airtight box body. When the box body is in a closed state, the air extraction device draws air from the box body to form a low-pressure vacuum state in the box body, effectively reducing the amount of items The probability of oxidation, deterioration, and mildew occurs, and the air flow on the surface of the item is reduced, thereby prolonging the preservation time of the item. [0003] It can be understood that, before taking out the items, it is necessary to perform a pressure release operation on the box body in a vacuum state. ...
