Abstract

Bekannt ist ein kontaktwärmeübertragendes elektrisches Kochsystem mit einem Kochplattenkörper zur Erwärmung eines auf dessen Oberseite abstellbaren Kochgefäßes, mit einem an dessen Unterseite gehalterten, zentral angeordneten ersten Heizelement und zumindest einem dazu peripher angeordneten zweiten Heizelement, denen jeweils zumindest ein Temperatursensor zugeordnet ist, und mit einer Steuereinheit, die mit den Heizelementen und den Temperatursensoren zur Steuerung der Heizleistung des Kochsystems verbunden ist. Um den hohen Wirkungsgrad des Kochsystems bei beliebigen Topfbodenkonturen sicherstellen zu können, stellt die Steuereinheit durch die Vorgabe definierter Heizleistungen der Heizelemente einen Temperatur- bzw. Längenausdehnungsgradienten in dem Kochplattenkörper von dessen Zentralbereich zu dessen Peripherbereich ein, wodurch eine definierte Wölbung des Kochplattenkörpers zur Minimierung des Abstandes zwischen der Oberseite des Kochplattenkörpers und dem Kochgefäßboden eingestellt ist.

Known is a contact heat-transmitting electric cooking system with a hotplate body for heating a cooking vessel that can be placed on its top, with a centrally arranged first heating element held on its underside and at least one second heating element arranged peripherally thereto, to which at least one temperature sensor is assigned, and with a control unit , which is connected to the heating elements and the temperature sensors for controlling the heating power of the cooking system. In order to be able to ensure the high efficiency of the cooking system with any pot base contours, the control unit sets a temperature or linear expansion gradient in the hotplate body from its central area to its peripheral area by specifying defined heating powers of the heating elements, which results in a defined curvature of the hotplate body to minimize the distance is set between the top of the hotplate body and the bottom of the cooking vessel.
