Kind Code:
A1
Abstract:
The present application provides a vacuum preservation apparatus and a refrigerator. The vacuum preservation apparatus comprises a vacuumizing component, a preservation box bracket and a movable component. An air extraction interface is provided on the vacuumizing component, and the preservation box bracket is movably mounted at the vacuumizing component by means of the movable component and is used for holding a preservation box. The preservation box bracket comprises: a first state far from the vacuumizing component, and a second state near to the vacuumizing component. Applying the technical solution of the present application, when the preservation box needs to be vacuumized, the preservation box bracket is operated by means of the movable component, so that the preservation box can be placed on the preservation box bracket by positioning the preservation box bracket to the first state; and then the preservation box bracket can be operated to enable the preservation box bracket to move to the second state, so that the vacuumizing component vacuumizes the preservation box.
