  • Patent number: 6557366
    Abstract: An apparatus for cold-holding food product. The apparatus comprises a cabinet carrying a refrigeration unit including a plurality of refrigerated shelves. The plurality of refrigerated shelves are adapted to frost on both sides under the control of the refrigeration unit to thereby maintain the quality of food product held on the shelves. To allow for the drainage of any melting frost, the plurality of shelves may be angled and a drain pan system included to direct the water away from the shelves to a drain or condensate evaporator during defrost periods. To prevent the removal of frost with the unloading of food products from the shelves, wire racks or trivets may be used to elevate the food product on baking pans above the frosted shelve surfaces.

    Abstract: A temperature controlled drawer assembly incorporates a thermoelectric device and a control system to selectively heat or cool the contents of a drawer which is selectively movable into and out of a cabinet designed to be part of an end table, such as a nightstand, or other cabinet remote from a household kitchen. In a cooling mode of operation, a fan, disposed in the cabinet, draws air from inside the drawer and blows the air over a cold side of a heat sink to cool the air. The treated air is blown through plenums, back into the drawer. At the same time, heat is drawn away from the cold side and directed out of the cabinet. The current through the heat sink may be reversed to flip the cold and hot sides of the heat sink to enable the contents of the drawer to be heated.

Small environmental control units ("ECUs") are mounted on top of individual mini-enclosures, as near as possible to the process tool within the enclosure. Each ECU has the capability of controlling temperature, humidity, and airflow rate delivered into the enclosure. Temperature is adjusted by first cooling the air inside the ECU followed by reheating it to a selected temperature. The cooling capability is not generated by individual ECUs. Instead, a remote fluid cooling unit supplies chilled fluid to each ECU, which is circulated internally to cool the air. The same remote unit services different ECUs at the same time.
