Abstract: A air circulator for an oven includes a housing having inlet and outlet walls with openings in each wall for permitting air to pass through the housing. The air circulator further includes a fan assembly within the housing having a rotatable fan element and a plurality of fan blades attached radially about the fan element for drawing air through the housing upon rotation of the fan element. A spring motor assembly is positioned within the housing and coupled with the fan assembly for rotating the fan element. The air circulator further includes a heat sensitive switch formed of a combination of metals which contracts upon an increase in the ambient air temperature of the oven for activating the spring motor.

Abstract: An air circulator for an oven is described formed of a self-contained housing sized to be placed at a convenient location inside the oven with food being heated. The housing encloses a spring motor and a propeller connected to the motor through a reduction gear train. An air flow is produced from a housing outlet adjacent the propeller and may be directed in a desired direction by a rotatably adjustable air flow deflector on the housing and at the outlet.
