Abstract
A vacuum storage system in a refrigerator includes a bin or drawer unit removably received in a housing. The vacuum storage system may be utilized in a storage configuration or in a vacuum sealing configuration to remove air from one or more food preservation containers having one-way evacuation valves. A switch on a control interface actuates a vacuum source and a front wall of the bin or drawer unit seals against the cabinet. Air is drawn from the storage space via a hose in communication with the vacuum source and air pressure within the storage space is reduced below atmospheric pressure, whereby air is simultaneously evacuated from the containers housed in the storage space. At a predetermined pressure, a control deactivates the vacuum source and an equalizing valve is opened to return the storage space to atmospheric pressure.
