Vacuum compartment in refrigerator |
摘要 |
A refrigerator comprises a vacuum source and a food storage compartment including a drawer unit having a storage space. The food storage compartment is operable between a substantially air-tight retracted position and an open extended position. A vacuum source is in communication with the storage space of the drawer unit and is operable to reduce air pressure inside the drawer unit during an evacuation event. A sealing unit includes a base connected to the drawer unit. A sealing bracket is hingedly-connected to the base and operable between a raised position and a lowered position, the sealing bracket adapted to abut the base when in the lowered position. A heat sealing bar is disposed on one of the base and the sealing bracket. A control system is operable to activate the vacuum source and initiate the evacuation event when the drawer unit is in the air-tight retracted position.
