ABSTRACT:
An electrically heated convection oven with built-in rotisserie for rotisserie roasting, baking, broiling, defrosting, and dehydrating foodstuff is characterized by the use of two motors. One for operating a fan which rotates within the heating chamber to create high velocity air flow throughout the heating chamber; the second one for rotating the rotisserie spit. The second motor is also utilized to drive a cooling fan that draws air over electronic controls to keep them safely cool. The electronic controls comprise a microcomputer which is pre-programmed to recognize input from a user and to process information from an air temperature sensor in the oven. The heating chamber features generously radiused, interior surfaces which from an integral, parabolic, reflective surface with substantial width for enhancing air flow, to increase air velocities and create evenness of heat within the heating chamber, thereby contributing to the performance of the oven.
