Abstract

Die Erfindung bezieht sich auf ein Kochgerät mit einer Glaskeramikplatte (10), mit mindestens einem unter der Platte (10) angeordneten Heizstrahler (11), mit mindestens einem unter der Platte (10) in einem gegen die Heizstrahlung (16) abgeschirmten Bereich (20) angeordneten Sensor (14) zur Messung der Temperatur dieses Bereiches (20) und mit einer Einrichtung (25) zur Regelung der Heizleistung in Abhängigkeit der vom Sensor (14) gelieferten Signale. Eine einfache und zuverlässige Methode zur Messung der Topf-Bodentemperatur kann dadurch erreicht werden,

  • daß als Heizstrahler ein Halogenlampensystem (12) und als Heizplatte eine für Halogenstrahlung (16) gut durchlässige Keramikplatte (10) mit einem Absorptionsgrad von etwa ≦ 40% vorgesehen ist,
  • daß der Sensor (14) an der Unterseite der Keramikplatte (10) anliegt und
  • daß die Regeleinrichtung (25) mit einer Anordnung (25a) zur Einstellung einer Solltemperatur versehen ist.

The invention relates to a cooking appliance with a glass ceramic plate (10), with at least one radiant heater (11) arranged under the plate (10), with at least one under the plate (10) in an area (20) shielded from the heating radiation (16) ) arranged sensor (14) for measuring the temperature of this area (20) and with a device (25) for regulating the heating power as a function of the signals supplied by the sensor (14). A simple and reliable method for measuring the pot bottom temperature can be achieved by
  • that a halogen lamp system (12) is provided as the radiant heater and a ceramic plate (10) which is well permeable to halogen radiation (16) and has a degree of absorption of approximately ≦ 40% as the heating plate,
  • that the sensor (14) rests on the underside of the ceramic plate (10) and
  • that the control device (25) is provided with an arrangement (25a) for setting a target temperature.
