Abstract
A cooking appliance includes an exhaust system that substantially eliminates potential smoke generating byproducts carried by oven gases. The cooking appliance includes an oven cavity having a top wall including a recessed portion within which is mounted a broil element. A plurality of openings are formed in the recessed portion that allow exhaust gases to pass into a smoke elimination chamber. Heat generated by the broil element and in the smoke elimination chamber removes substantially all combustion byproducts contained in the exhaust gases. To further remove combustion byproducts, the exhaust gases are passed through a ceramic catalyst prior to being directed into a vent duct. From the vent duct, the exhaust gasses are directed past a blower into an exhaust duct that, ultimately, guides the exhaust gases from the appliance.
