Definitions

  • the invention relates to a stove with pyrolytic Self-cleaning, the muffle by one in at least one Wall area arranged heating element and optionally with additional air heating can be operated, the muffle ventilated by a forced air fan and with pyrolytic agents Self-cleaning is equipped and in the exhaust air the muffle is a gas sensor connected to an evaluation unit is arranged.
  • a stove with pyrolytic Self-cleaning the muffle by one in at least one Wall area arranged heating element and optionally with additional air heating can be operated, the muffle ventilated by a forced air fan and with pyrolytic agents Self-cleaning is equipped and in the exhaust air the muffle is a gas sensor connected to an evaluation unit is arranged.
  • the energy consumption in the previously known methods of pyrolytic self-cleaning to eliminate the above Soiling was defined by one on one Time kept high temperature marked from 480 to 500 °.
  • the object of the invention is that for the pyrolytic Self-cleaning process required heating energy to a necessary Minimize dimensions without affecting existing ones Herds major changes need to be made.
  • FIG. 1 shows this in the course of the curve 2.
  • the curve profile according to FIG. 1 according to FIG. 1 is what has already been said removable, i.e. a heating-up time of 40 minutes, a holding time of 80 minutes and the one that starts afterwards Cooling process without heating operation. You want the pyrolysis process improve energetically, i.e.
  • the duration of the heating-up time depends on which stove-specific designs and sizes of the cooking space, how far the stove is when the Pyrolysis is already warmed up and how high the Mains voltage during the pyrolysis period. According to Fig. 1 of the curve profile 1 can be seen that at one Starting temperature of 200 ° C after an oven process the pyrolysis heating-up time can be shortened significantly, with the subsequent standard holding time of 80 minutes consequently the process faster and less energy.
  • FIG. 2 a diagram is shown which uses the prevailing mains voltage as a parameter and, depending on the starting temperature, indicates the shortening of the heating-up time that then occurs.
  • the reference numerals 3 to 8 mean different parameters of the mains voltage.
  • Reference number 3 corresponds to a mains voltage of 215 V
  • Reference number 4 corresponds to a mains voltage of 220 V
  • Reference number 5 corresponds to a mains voltage of 225 V
  • Reference number 6 corresponds to a mains voltage of 230 V
  • Reference number 7 corresponds to a mains voltage of 235 V
  • Reference number 8 corresponds to a mains voltage of 240 V.
  • the evaluation unit is dependent of the real mains voltage for the respective Oven outlet temperature as parameter the heating time corrected.
  • the evaluation unit ends the pyrolytic Self-cleaning process after a holding time of approx. 80 minutes, the holding time when the pyrolysis setpoint temperature is reached, which depends on the degree of pollution analysis, begins.
  • the holding time is the maximum guideline time understand an underlying time can from the evaluation unit be specified when the degree of pollution analysis this justifies.
  • the evaluation unit breaks after the total time by the heating time and the holding time given, the self-cleaning heating process of 120 minutes from.
  • the evaluation unit makes sense that do not exceed an upper pyrolysis temperature of 480 ° C otherwise the enamelled parts of the stove interior Get damaged. Therefore the evaluation unit as the maximum pyrolysis setpoint temperature of 480 ° C.
