Zusammenfassung:	The present disclosure provides a refrigerator including a vacuum sealing device disposed at an outer side of a door. The vacuum sealing device includes a lower support, an upper support and a vacuumization assembly. The upper support moves close to or away from the lower support under the drive of a driving device; after the upper support moves at a first speed until a sealing ring of the upper support is in contact with a sealing ring of the lower support, the upper support moves at a second speed toward the lower support until the sealing ring has a set deformation amount, and a first opening cavity and a second opening cavity are butt-joined to sealingly form a vacuumization region; the first speed is greater than the second speed; the vacuumization assembly is in communication with the vacuumization region through a pipe to perform vacuumization or depressurization for the vacuumization region.
