Abstract
A stove with pyrolytic self-cleaning includes an oven having at least one wall region and an outgoing air path. A heating element is disposed in the at least one wall region for operating the oven. A forced-air and/or convection blower vents the oven. A forced-air and/or convection heater is optionally provided for the oven. A device is provided for pyrolytically self-cleaning the oven. A gas sensor is disposed in the outgoing air path for issuing sensor signals. An evaluation unit for pyrolytic self-cleaning is connected to the gas sensor. The evaluation unit has a logic system adapted to a pyrolysis operation for analyzing the sensor signals. The evaluation unit uses the sensor signals after a typical pyrolysis operating time to determine a minimum pyrolysis temperature and an optimized total pyrolysis time being dictated by a type of soiling.
