摘要： 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. In one embodiment, an axial-type hot-air fan guides the hot air in a substantially axial direction within the cooking chamber, and a fan shroud surrounds the hot-air fan so that a radial component of the hot air is initially routed in a substantially axial direction off of the hot-air fan into the cooking chamber of the oven.

摘要： 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.

摘要： A modular food dehydrator utilizing a heater blower assembly located on a top surface of a dehydrator module. The heater blower assembly includes a motor driven fan, a heating element and an air distribution portion for directing heated air across the support surfaces. The heater blower assembly is preferably releasably attachable to the dehydrator module. In a first embodiment, the dehydrator module has a central opening extending generally vertically through the support surfaces in fluid communication with the heater blower assembly for directing heated air radially outward across the plurality of support surfaces. The dehydrator module preferably includes outlet vents on an outer perimeter surface for exhausting the heated air. At least one outlet vent is preferably located between each of the plurality of support surfaces. In a second embodiment, the dehydrator module includes air ducts on an outer perimeter surface in fluid communication with the heater blower assembly for directing pressurized, heated air radially inward across the plurality of support surfaces. The dehydrator module includes a central opening extending generally vertically through the support surfaces in fluid communication with a space between each the support surfaces for exhausting or recirculating heated air.

摘要： 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. The intake air is filtered and the electrical heater is temperature controlled by a thermister-triac combination or bi-metallic thermostat which senses the temperature within the plenum and controls the current flowing through the electrical heating element.
