Abstract
An assembly of vertically spaced ovens with an air passage at the bottom of the upper oven and top of the lower oven having an inlet at the rear, and an outlet at the front of the assembly. An air moving device is provided for causing air flow forwardly through the passage to cool the oven structure. At least one of the ovens may be a microwave oven and the air moving device may serve to draw air from the interior of the microwave oven for delivery forwardly through the passage. At least one of the ovens may be provided with a front door having a vertical air flow passage for convective cooling of the door. The forward passage outlet may be disposed adjacent the upper end of the door vertical passage whereby the forceful air movement from the air moving device may draw air through the vertical passage for improved cooling of the door. A thermostat control may be provided for causing automatic operation of the air moving device. At least one of the ovens may include an integral air circulating structure to provide independent cooling thereof. The air moving device may draw air from about the upper oven and through the upper oven for delivery forwardly through the passage between the…
