The specification discloses a self-cleaning oven including an outer housing with an oven liner disposed within the housing in a spaced-apart relationship forming cavities between the housing and liner walls. A duct system is provided for directing air from the vicinity of the lower front and rear of the oven to the cavity between the top walls of the housing and liner. A heating element is mounted in a proximate relationship to a smoke eliminator panel mounted on the top liner wall. Smoke and gases emanating from the oven pass through apertures formed in the smoke eliminator panel to a vent tube. The vent tube discharges gases from the smoke eliminator panel into a discharge duct above the oven liner. A diluter tube encompassing the vent tube allows air to pass from the cavity between the top walls of the oven liner and the housing into the discharge duct. The air dilutes the smoke and gases from the oven liner, and the diluted smoke and gases are then exhausted from apertures in the front of the oven. In this arrangement, air flow results from thermal currents, and a fan is not required.
