ABSTRACT:
A cooking oven of the heat-cleaning type in which substantially all of the energy for heating the oven to heat-cleaning temperature is initially supplied by the upper or broil heating element. The broil unit is initially energized to raise the oven cavity temperature to the heat cleaning range during which time volatile portions of food by-products are evaporated, whereupon the broil unit is de-energized and the lower or bake heating element energized to maintain the temperature of the oven cavity in the heat cleaning range. The location of the lower bake unit relative to the lower wall of the oven cavity is dimensioned to insure that the temperature of the more difficult to clean front portion of the lower wall of the oven adjacent the door opening is maintained at heat-cleaning temperature for a time sufficient to effect removal of food by-products.
