ABSTRACT:
A forced air convection oven includes a cooking compartment and an air heating chamber adjacent to one wall of the cooking compartment. An air circulating fan and an air heater are mounted in a central section of the chamber. An elongated section of the chamber extends from the fan along the compartment wall and has an uniformly decreasing cross section area. There is an inlet opening in the compartment wall aligned with the fan and a plurality of outlet openings uniformly spaced apart along the compartment wall communicating with the elongated chamber section. Each outlet opening has a cross sectional area equal to the cross section area of the end of the elongated section adjacent to the fan divided by the number of outlet openings.
