Abstract
A microwave oven having a cooking cavity for receiving objects to be heated during the oven cooking cycle arranged to permit continuous circulation of air through the cavity during the cooking cycle, an exhaust flow path to the oven exterior formed externally of the cavity for circulating air exiting the cavity, and sensing means responsive to vapors and/or gases carried by the exiting air positioned in the exhaust flow path, is provided with a pyrolytic converter positioned in the exhaust flow path upstream of the sensing means for converting non-gaseous contaminants carried by the exiting air during the cooking cycle to gaseous form. Removal of non-gaseous contaminants from the air exiting the cooking cavity upstream of the sensor prevents accumulation of such contaminants from interferring with proper sensor operation without interrupting the cooking cycle and without requiring periodic manual cleaning of the sensor device.
