Abstract: The present disclosure provides a refrigerator, including a storage compartment and a door opening or closing the storage compartment. A vacuum sealing device is disposed on the door. The vacuum sealing device includes an upper support and a lower support opposite to each other and a vacuumization assembly. The lower support is detachably connected to the door; opening cavities are formed on mutually-opposed surfaces of the upper support and/or the lower support; the upper support can move close to or away from the lower support under the drive of a driving device; the upper supports moves close to the lower support until the upper support and the lower support are butt-joined, and the opening cavities sealingly form a vacuumization region by sealing portions; the vacuumization assembly is in communication with the vacuumization region through a pipe to perform vacuumization or depressurization for the vaccumization region.

Abstract: 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.
