Abstract

Die Erfindung geht aus von einer Heizvorrichtung (2) für ein Induktionsgargerät, umfassend einen Induktor (4) zur Erwärmung eines Heizelements (10) eines Garbehälters (8) und eine Steuereinheit (12), die dazu vorbereitet ist, das Heizelement (10) auf das Erreichen einer Kochtemperatur zu überwachen.The invention is based on a heating device (2) for an induction cooking appliance, comprising an inductor (4) for heating a heating element (10) of a cooking container (8) and a control unit (12) which is prepared for heating element (10) to monitor the reaching of a cooking temperature.

Es wird vorgeschlagen, dass die Überwachung durch die Einstellung einer Frequenz (f) des Wechselstroms, der den Induktor (4) durchfließt, und die Erfassung zumindest einer elektrischen Größe (p) in Abhängigkeit von der Zeit (t) erfolgt. Hierdurch kann die Kochtemperatur besonders einfach, zuverlässig und schnell überwacht werden.

Figure imgaf001
It is proposed that the monitoring takes place by setting a frequency (f) of the alternating current flowing through the inductor (4) and the detection of at least one electrical variable (p) as a function of the time (t). As a result, the cooking temperature can be monitored very easily, reliably and quickly.
