Abstract
The present invention provides a vacuum storage device and a refrigerator. The vacuum storage device comprises a housing, a cover, an evacuation assembly, a pressure relief assembly and an adjuster; the pressure relief assembly comprises a pressure relief hole, a sealing plug covering the pressure relief hole in a natural state, and a pressure relief element having a pressure relief slider; the adjuster drives the pressure relief slider to get close to or away from the sealing plug without being affected by an external force. The structure is simple and the sealing effect is better.
