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 optionally with additional circulating air heating, the muffle being ventilated by a circulating air blower and equipped with means for pyrolytic self-cleaning and the muffle in the exhaust air path gas sensor connected to an evaluation unit is arranged.
  • the energy consumption in the previously known methods of pyrolytic self-cleaning to remove the above-mentioned types of contamination was characterized by a temperature of 480 to 500 ° held high for a defined time.
  • the object of the invention is to minimize the heating energy required for the pyrolytic self-cleaning process to a necessary extent without having to make significant changes to existing cookers.
  • an evaluation unit proposes a pyrolytic self-cleaning process to the user when a sensor-monitored, defined degree of soiling is present, when an oven cooking process has ended and when the oven start temperature for the pyrolytic cleaning process corresponds to a temperature-time profile that can be queried in the evaluation unit.
  • FIG. 1 shows this in the course of the curve 2.
  • the course of the curve according to FIG. 1 according to FIG. 1 shows what has already been said, that is to say a heating-up time of 40 minutes, a holding time of 80 minutes and the subsequent cooling process without heating operation.
  • a saving effect is only possible by shortening the heating-up time.
  • the duration of the heating-up time depends on which stove-specific constructions and sizes of the cooking space are available, how far the stove has already warmed up when the pyrolysis mode is started and how high the mains voltage is during the pyrolysis period. According to Fig. 1 of the course of the curve 1 can be seen that at a starting temperature of 200 ° C after an oven operation, the pyrolysis heating time can be shortened significantly, with the subsequent standard holding time of 80 minutes, the process is therefore faster and less energy-intensive.
  • the holding time of the pyrolytic self-cleaning process is kept constant, an energy gain can be realized which proceeds proportionally to the time gained during the heating-up time according to the starting temperature in the muffle.
  • the total time saved in constant holding time is from 4 minutes for 100 ° C start temperature to 16 minutes at start temperature of 300 ° C.
  • start temperature For an average oven start temperature of 150 ° C
  • 7 minutes are saved, which corresponds to approximately 5.3% of the total duration and a proportional gain in energy.
  • curve 5 results in a heating-up time of 30 minutes for a starting temperature of 200 ° C. This can be read exactly from the graph 1 that can be seen in FIG. 1. According to FIG. 2 of curve shape 5, the starting point of curve shape 2 can also be seen. It can be seen that the heating-up time is 40 minutes at a room temperature of 20 to 25 ° C, corresponding to diagram 2 in FIG. 1. The time gains for increasing mains voltages are not significant, but they are significant in the overall process. From the point of view of energy saving, it appears sensible that the evaluation unit then suggests to the user a pyrolytic self-cleaning process if the starting temperature for the pyrolytic self-cleaning process is above 100 ° C.
  • the evaluation unit corrects the heating-up time as a parameter depending on the real mains voltage for the respective oven outlet temperature.
  • the evaluation unit ends the pyrolytic self-cleaning process after a holding time of approx. 80 minutes, the holding time beginning when the pyrolysis setpoint temperature, which depends on the degree of contamination analysis, is reached.
  • the holding time is to be understood as the maximum guideline time; a time below this can be determined by the evaluation unit be specified if the degree of pollution analysis justifies this.
  • the evaluation unit stops the self-cleaning heating process after the total time, which is given by the heating-up time and the holding time, of 120 minutes. In addition, it makes sense that an upper pyrolysis temperature of 480 ° C is not exceeded, since otherwise the enamelled components of the stove interior will be damaged. The evaluation unit therefore allows 480 ° C as the maximum pyrolysis setpoint temperature.
