  • Patent number: 5520096
    Abstract: A handle adapted for replacing a heater and blower system removably located in a central opening defined a top enclosure of a countertop oven. The handle comprises a mounting system for removably attaching the handle to the top enclosure in order to replace the heater and blower system when the heater and blower system is removed. The handle enables a user to remove the top enclosure from the bottom enclosure by lifting up on the handle when the handle is installed in the top enclosure. In this manner, the countertop oven may be converted to a food server comprising the handle, the top enclosure, and the bottom enclosure.

  • Patent number: 5466912
    Abstract: A convection oven includes a frame having a base member and two upright members which extend upwardly from the base member. A cooking chamber is removably supported by the frame and includes an upper enclosure member and a lower enclosure member. A housing attached to the upper enclosure member is configured so that cool air flows from a peripheral portion of an arm into a central portion of the housing and then is expelled from the arm over the upper surface of the upper enclosure member. A passive hinge connects the housing to the frame such that the housing and upper enclosure member may be both separated from the frame and lower enclosure member by lifting the housing vertically and pivoted relative to the frame and lower enclosure member. An extension ring selectively enlarges the size of the cooking chamber. A holster may hold the upper enclosure member and the housing when they are separated from the lower enclosure member.

  • Patent number: 5438916
    Abstract: A rack invention includes a rack having a rack surface and a plurality of legs attached to the rack surface. Each of the legs is made of wire and has two straight segments extending downwardly from the rack surface and a connecting segment which connects together the straight segments. The connecting segment is shaped so as to allow the rack surface to be placed at one of a plurality of predetermined distances above the surface in the oven. The cooking rack invention also includes a plurality of such racks which may be used together in an oven. In such an instance, the length of the straight segments of one rack are different that those of another rack, so that the racks provide different ranges of height adjustability.

  • Patent number: 5420393
    Abstract: Assemblies for increasing airflow and heating efficiency in a multi-shelf food heating device having a base, a plurality of circular vertically stacked trays, and a top, wherein the airflow within the device is assisted by a fan is disclosed. One assembly involves a biasing system supported in the base for biasing the motor in place. Another assembly involves a thin, substantially planar constructed heater and a radial fan supported within a chamber of the base of the device, wherein the heater is aligned with the movement of the airflow within the chamber so that the airflow therein is substantially unobstructed by the heater. Another assembly involves providing the base with a wall substantially surrounding and adjacent an air inlet in the base to define a cavity into which substantially all of the airflow from the air inlet is directed, so that the motor is continuously cooled during operation of the device.

  • Patent number: 4536643
    Abstract: The present food dehydrator may be substantially cylindrical in shape including a base member, a plurality of stackable trays, and a top. The base member has a first chamber adapted for receipt of a heater element for convection air distribution and a second chamber adapted for receipt of a heating element suitable for forced air distribution. The base member further includes a chamber adapted for receipt of an electric fan motor. The dehydrator is convertible between a convection heating made and a forced air heating made by selectively mounting the convection heating element and the forced air heating element in their respective chambers.

  • Patent number: 4224743
    Abstract: A machine for dehydrating food, as an aid toward preservation of food for extended periods of time. Intake air may be obtained from either the exterior of the machine or a combination of exterior and recycled air. Intake air is electrically heated and pressurized in a plenum chamber by a fan. The pressurized and heated air is released in a uniform laminar flow through a set of small openings, then along horizontally disposed shelves containing the food to be dried. The air is then selectively discharged into the atmosphere or a portion thereof is recycled and combined with new intake air and again passed over the food to be dehydrated. The percentage of recycled air is selectively variable over a wide range. Removable frames support either solid sheets or screens having mesh openings of desired sizes which support the food to be dried. The choice of a solid sheet or the mesh size depends upon the type of food to be dried.
