发明名称 Refrigerator door vacuum preservation system
摘要 A refrigerator includes a hands-free vacuum preservation system mounted on a door of the refrigerator comprising a main body portion having a slot therein for receiving an open end of a plastic bag. Sensors within the slot detect the presence of the bag and a retaining device is actuated to punch holes in the bag and retain the bag in position for a vacuum sealing event. An intake port within the system communicates with a vacuum source to remove air from the bag, and a heat sealer seals the bag closed. In a preferred embodiment, once sensors located on the main body portion detect the presence of a consumer's hand, the retaining device releases the bag. The resultant vacuum sealed bag can be stored in a conventional manner, or by hanging the bag from hooks extending through the holes formed therein by the retaining device.
