Abstract
A pyrolytic self-cleaning stove includes at least one wall region defining an oven chamber, a muffle disposed in the at least one wall region, a heating element with additional ambient air heating for operating the muffle, an ambient air blower for ventilating the muffle, a device associated with the muffle for pyrolytic self-cleaning, and a sensor array disposed in the cooking chamber for detecting oven soiling values caused by operation. A pyrolytic self-cleaning method for stoves includes on-line optimization of a definable pyrolysis temperature range up to approximately 500.degree. C. by fuzzy-controlling a transient state for a temperature starting value with a regulating device, to avoid a heating startup peak with a fuzzy control step; recognizing subsiding of the transient state and initializing an optimized heating time referred to the fuzzy control step, with the regulating device; updating a minimum heating time for the next control step on the basis of the particular temperature gradient being recognized, while constantly monitoring the optimal turn-on temperature for the pyrolytic oven chamber heating, with the regulating device, at a minimum heating time referred to a…
