Abstract

Die Erfindung betrifft ein elektrisches Kochfeld für den Niederspannungsbereich mit einer Kochplatte aus Hochleistungskeramik und mit einem Heizleiter, der mit der Unterseite der Kochplatte einen Flächenkontakt bildet. Um sicherzustellen, daß sich die elektrischen Versorgungsleitungen aufgrund der hohen Ströme im Niedrigspannungsbereich nicht übermäßig erhitzen, ist zwischen dem Heizleiter und den elektrischen Versorgungsleitungen jeweils mindestens ein Leitungselement zwischengeschaltet, das einen Widerstandswert aufweist, der zwischen den Widerstandswerten des Heizleiters und der jeweiligen elektrischen Versorgungsleitung liegt.

Figure 00000001
The invention relates to an electric hob for the low-voltage range with a hotplate made of high-performance ceramic and with a heating conductor which forms a surface contact with the underside of the hotplate. To ensure that the electrical supply lines do not overheat due to the high currents in the low-voltage range, at least one line element is interposed between the heating conductor and the electrical supply lines, which has a resistance value that lies between the resistance values of the heating conductor and the respective electrical supply line.
