  • Patent number: 7101500
    Abstract: A sheet of plastic to be thermoformed into an appliance liner is brought to a substantially uniform temperature, preferably to a temperature differential of less than 5° F. throughout, by directing a fluid medium upon opposing side surfaces of the sheet. In the most preferred form of the invention, the fluid medium is constituted by air which is heated, impinged upon the opposing surfaces and recirculated, with the temperature and flow rate of the air being controlled based on sensed operating parameters.
    Type: Grant

  • 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.

  • 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: 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.

  • Patent number: 6036293
    Abstract: A refrigerator cabinet assembly includes a cabinet shell having opposed side walls that are interconnected by a top wall and a shell bottom. Each of the side and top walls of the shell lead to front face portions which are integrally formed with return flanges for use in mounting one or more liners within the cabinet shell in a manner known in the art. In accordance with the preferred embodiment, the shell bottom is spaced rearwardly of the return flanges such that a receiving slot is defined therebetween. The cabinet assembly further includes an integrated, structural reinforcing frame mounted within the cabinet shell by sliding the frame within the receiving slot and securing the frame to the return flanges. After mounting a yoder tube, a mullion bar and the liners within the cabinet shell, a plastic toe plate is attached to the reinforcing frame. The toe plate is provided with side flanges which extend about the side walls of the cabinet shell.
