Unter einer "Haupterstreckungsebene" eines Objekts soll insbesondere eine Ebene verstanden werden, welche parallel zu einer größten Seitenfläche eines kleinsten gedachten Quaders ist, welcher das Objekt gerade noch vollständig umschließt, und insbesondere durch den Mittelpunkt des Quaders verläuft. Dadurch kann eine Größe des Teilbereichs insbesondere auf jegliche Art von Gargeschirr angepasst werden, wodurch insbesondere eine unnötige Aktivierung von nicht benötigten Heizelementen vermieden und/oder eine energieeffiziente Ausgestaltung ermöglicht werden kann.A size of the partial area could be predefined, for example, the size and / or position being defined in particular by an arrangement of at least two and advantageously at least three sensors. In particular, the partial area could be marked optically. A size of the partial area is advantageously variable and, in particular, is dependent on a size of the cookware. For example, the size of the partial area could be adjustable by means of an operating unit, in particular certain heating elements and / or a certain area of the variable cooking area area being selectable. The control unit is advantageously provided to combine heating elements covered by the cooking utensils to form a heating zone in the event of detection of a set of cooking utensils, the heating elements defining the heating zone assigned to the cooking utensils defining a size of the partial area. The size of the partial area is at least essentially dependent on the size of a bottom surface of the cookware. A "size" of an area and / or element is to be understood in at least one operating state and / or in an installed position, in particular a surface extension of the area and / or element in a main plane of extent of the hob plate. A “main extension plane” of an object is to be understood in particular to mean a plane which is parallel to a largest side surface of a smallest imaginary cuboid, which still just completely surrounds the object and in particular runs through the center of the cuboid. As a result, a size of the partial area can be adapted in particular to any type of cookware, which in particular prevents unnecessary activation of heating elements that are not required and / or enables an energy-efficient design.
Weiterhin wird vorgeschlagen, dass der Teilbereich zumindest einen Sensorbereich aufweist, welcher wenigstens im Wesentlichen eine Position des Teilbereichs festlegt.

The sensor is provided, in particular, for detecting cookware set up and / or for detecting a temperature of at least one cookware set up. The phrase that the sensor area “at least essentially” defines a position of the partial area is to be understood in particular to mean that the sensor area forms at least a first part of the partial area, at least a second part of the partial area depending in particular on a position of at least one set up Cooking utensils could extend in different directions in the variable cooking surface area. For example, the sensor area could be arranged in an edge area and / or in a center point and / or in a center of gravity of the partial area. In particular, this enables simple operation and / or makes it easier to mark the position of the partial area.
