<p>A self-cleaning combination microwave and electrically heated oven having a rotating microwave radiator positioned beneath a microwave transparent protective cover of high temperature material with air being blown by a microwave source into the oven through the radiating system and impinging on the cover, thereby cooling and assisting in preventing deposition of cooking vapors on the cover. During the self-cleaning cycle, air is drawn by convection through the oven to maintain the radiating system below 650.degree.F while the interior oven surfaces are raised to temperatures above 900.degree.F by resistive heating elements in the oven.</p> |
