ABSTRACT:
Disclosed is a domestic cooking range of the ventilated type having surface elements and an underlying oven characterized by an extension of the ventilating fan motor shaft carrying an auxiliary fan disposed within the oven which provides forced circulation of air in the oven. The oven may thus be selectively operated in the conventional radiant heating mode or in the forced circulation or "convected" mode depending upon whether the ventilating fan motor is in operation. The oven can be held at an elevated temperature (of the order of 550.degree. F) for a time interval to accelerate catalytic self-cleaning (catalyst added to the porcelain frit covering the oven surface) because of air circulation within the oven door and passages adjacent the door, this cooling air flow being induced by operation of the ventilating fan.
