Definitions

  • the invention relates to a stove with pyrolytic self-cleaning
  • the muffle can be operated by a heating element arranged in at least one wall area and possibly with additional circulating air heating, the muffle being ventilated by a circulating air blower and equipped with means for pyrolytic self-cleaning.
  • the muffle walls are heated to a temperature of 480 to 500 ° C during the passage of a predetermined time-temperature profile and kept at a high temperature for a certain time, this time corresponds to an empirical value and does not reflect the actual conditions of the muffle contamination.
  • the relatively long-chain molecules of the dirt adhering to the walls of the muffle are subjected to a thermal cracking process as a result of the long-lasting heating to over 450 ° C. and are thus converted into relatively short-chain degradation products, for example water, short hydrocarbons, aromatics and ash residues.
  • the gaseous degradation products are removed from the stove with the ventilation during self-cleaning. After self-cleaning, the remaining residues can simply be removed from the stove as ash.
  • the stove is locked to prevent accidents and is only released for use once the temperature drops below a specified threshold.
  • the object of the invention is now to carry out the pyrolytic self-cleaning operation as a function of the real contamination rate.
  • the solution to this problem according to the invention is characterized in that a gas sensor connected to an evaluation unit for pyrolytic self-cleaning is arranged in the exhaust air path of the muffle, that the evaluation unit analyzes the sensor signals with a logic system adapted to the pyrolysis operation and that the evaluation unit from the sensor signals after a typical pyrolysis Operating time determines a pollution-related pyrolysis minimum temperature and an optimized total pyrolysis cooking time.
  • a further advantageous embodiment of the invention is characterized in that the evaluation unit, which is partially equipped with an unsharp logic system, predetermines the total pyrolysis time required depending on the degree of contamination, is corrected in relation to the sensor signal, and switches off the heating elements after these times have elapsed. Further advantageous embodiments of the invention are presented in the subclaims.
  • 1 and 2 show diagrams which, in parametric assignment, represent various contamination values with the associated sensor signal profiles.
