  • Stove with a capacitive sailing sensor and sensor-controlled starting of pyrolysis
    Patent number: 5343020
    Abstract: A stove with pyrolytic self-cleaning includes an oven having an oven space, at least one wall region, a heating element disposed in the at least one wall region, a forced-air blower for venting the oven, a device for pyrolytic self-cleaning, and an optional forced-air heating device. A sensor system is disposed in the oven space for detecting operationally dictated oven soiling values and issuing input values. An evaluation circuit has an input connected to the sensor system for frequency-converting the input values, for digitizing the input values, for counting the input values, for storing the input values, and for concatenating the input values. The evaluation circuit has an output side signaling a degree of soiling and the evaluation circuit recommends and/or carries out an initiation of pyrolysis.
