Abstract: A convection and radiant heated oven has a cooking chamber and an air heating chamber below and spaced from the cooking chamber. Shield means above the heating chamber defines, with the oven bottom, a heat space in which an apertured duct receives heated air from the heating chamber and conducts it to a convection fan where it mixes with air from the cooking chamber and is ducted into the cooking chamber. Heated air is also passed upward from the heat space directly into the cooking chamber.
