Refrigerator

A refrigerator, comprising a storage compartment and a door opening or closing the storage compartment, wherein a vacuum sealing device is disposed on the door and comprises:

• an upper support and a lower support;
• wherein opening cavities are disposed on mutually-opposed surfaces of the upper support and/or the lower support;
• sealing rings surrounding the opening cavities of the upper support and/or the lower support are disposed;
• the upper support moves close to or away from the lower support under the drive of a driving device;
• when the upper support moves close to the lower support until the upper support and the lower support are butt-joined, the opening cavities sealingly form a vacuumization region by sealing rings;
• a vacuumization assembly, wherein the vacuumization assembly comprises a vacuum pump in communication with the vacuumization region through a pipe;
• a pressure detection device and a pressure relief device are further disposed on the pipe, the pressure detection device, the pressure relief device and the vacuum pump are in electrical connection with a controller respectively, the pressure detection device detects a pressure of the vacuumization region after the vacuum pump is started, and when the controller determines the vacuumization region is abnormal according to a detection signal of the pressure detection device, the controller controls the vacuum pump to stop and starts the pressure relief device to perform depressurization for the vacuumization region.
