  • Patent number: 6612116
    Abstract: A food storage system mounted in a fresh food compartment of a refrigerator includes an enclosure, as well as a food receptacle slidably positioned in the enclosure. A thermoelectric (TE) device is employed to establish a flow of temperature controlled air for establishing a desired temperature in the food receptacle. In accordance with one embodiment, the thermoelectric device is positioned in a chamber defined behind the food receptacle. In another embodiment, the thermoelectric device comprises a module located atop the enclosure.
    Type: Grant

  • Patent number: 6463752
    Abstract: A food storage system mounted in a fresh food compartment of a refrigerator includes an enclosure defined by inner and outer housings, as well as a food receptacle slidably positioned in the inner housing. The inner and outer housings are spaced so as to define a zone therebetween within which air is forced to flow in order to cool the contents of the receptacle. Inlet vents are provided in the inner housing to permit a portion of the cooling air to flow directly into the food receptacle, while the remainder of the air flow is directed about the inner housing for indirect cooling of the contents in the food receptacle.

  • Patent number: 6343477
    Abstract: A food storage system mounted in a fresh food compartment of a refrigerator includes an enclosure defined by inner and outer housings, as well as a food receptacle slidably positioned in the inner housing. The inner and outer housings are spaced so as to define a zone therebetween within which air is forced to flow in order to cool the contents of the receptacle. A temperature sensor is mounted within the inner housing, with signals from the sensor being sent to a control unit used to regulate the operation of a damper for controlling the flow of cooling air into the food storage system and a fan for distributing the cooling air within the food storage system. The control system also operates the damper and fan based on signals indicative of the opening and closing of the receptacle, the opening and closing of a door associated with the fresh food compartment and also the overall operation of the refrigerator.

  • Patent number: 6223553
    Abstract: A food storage system mounted in a fresh food compartment of a refrigerator includes an enclosure defined by inner and outer housings, as well as a food receptacle slidably positioned in the inner housing. The inner and outer housings are spaced so as to define a zone therebetween within which air is forced to flow in order to cool the contents of the receptacle. A tunnel insert is positioned in a mullion zone defined between fresh food and freezer liners of the refrigerator, with the tunnel insert being formed with a through hole for directing the flow of cooling air into the food storage system, a channel for directing an exhaust flow of cooling air from the food storage system out of the fresh food compartment within the mullion zone and an enlarged opening defining a return air passage for the overall fresh food compartment. The tunnel insert, within the mullion zone, channels the exhaust air from the food storage system to the return air passage.

  • Patent number: 6170276
    Abstract: A refrigerator crisper system includes an enclosure defined by inner and outer housings, as well as a food receptacle slidably positioned in the inner housing. The inner and outer housings are spaced so as to define a zone therebetween within which air, generated by a fan mounted entirely within the enclosure, is forced to flow in order to cool the contents of the receptacle. The enclosure is formed with various vanes that direct the cooling air flow above, adjacent the sides and below the receptacle. In the most preferred form of the invention, a temperature sensor and a moisture permeable film are provided to further regulate the food storage environment established in the receptacle.
