Insbesondere unterscheidet sich die variable Kochfläche von einer Kochfläche bei der Kochzonen, insbesondere durch Markierungen auf der Kochfläche, fest vorgegeben sind. Insbesondere ist die variable Kochfläche von zumindest einer Heizelementmatrix und/oder zumindest einem beweglichen Heizelement gebildet. Unter einer "Heizelementmatrix" soll insbesondere eine, vorzugsweise zweidimensionale, vorteilhaft regelmäßige Anordnung von zumindest vier, insbesondere zumindest 10, vorteilhaft zumindest 20, Heizelementen, insbesondere Induktionsheizelementen, verstanden werden.

Insbesondere unterscheidet sich die Navigationseinheit von einem berührungsempfindlichen Bildschirm. Es kann insbesondere eine kostensparende Ausgestaltung erreicht werden.It is proposed that the navigation unit be designed separately from the indication unit. A "variable cooking surface" is to be understood in particular as a cooking surface which is provided to form at least one cooking zone that is adapted to at least one cookware that has been set up.

Figur 4 zeigt eine Navigationseinheit 30a und eine Indikationseinheit 16a. Die Navigationseinheit 30a ist als Relativnavigationseinheit ausgebildet. Die Navigationseinheit 30a weist vier als berührungsempfindliche Bedienflächen, also Bedienflächen mit kapazitiven Sensoren, ausgebildete Bedienelemente 32a, 34a, 36a, 38a auf. Die Bedienelemente 32a, 34a, 36a, 38a repräsentieren jeweils eine der Navigationsrichtungen recht, links, hinter und vor. Eine Steuereinheit ist dazu vorgesehen, ausgehend von einer aktuell ausgewählten Kochzone 20a in Abhängigkeit von einem betätigten Bedienelement 32a, 34a, 36a, 38a eine entsprechend in der repräsentierten Richtung nächstliegende Kochzone 22a, 24a, 26a auszuwählen, wobei angenommen wird, dass die sich jeweils gegenüberliegenden Ränder der Indikationseinheit einen geschlossenen Kreis bilden. In Figur 4 ist eine Situation mit fünf dargestellten Kochzonen 20a, 22a, 24a, 26a, 28a gezeigt. Ausgehend von der ausgewählten Kochzone 20a würde bei Betätigung des Bedienelements 32a, das die Navigationsrichtung nach rechts repräsentiert, da die ausgewählte Kochzone 20a nahe am rechten Rand orientiert ist, die erste Kochzone 22a ausgewählt werden, die auf gleicher Höhe am nächsten am linken Rand angeordnet ist. Ausgehend von der ausgewählten Kochzone 20a würde bei Betätigung des Bedienelements 34a, das die Navigationsrichtung nach links repräsentiert, die nach links gesehen nächste Kochzone 24a ausgewählt werden. Ausgehend von der ausgewählten Kochzone 20a würde bei Betätigung des Bedienelements 36a, das die Navigationsrichtung nach hinten repräsentiert, da die ausgewählte Kochzone 20a nahe am hinteren Rand liegt ist, die erste Kochzone 26a ausgewählt werden, die auf gleicher Seitenlage am nächsten am unteren Rand angeordnet ist. Ausgehend von der ausgewählten Kochzone 20a würde bei Betätigung des Bedienelements 38a, das die Navigationsrichtung nach vorn repräsentiert, die nach vorn gesehen nächste Kochzone 26a ausgewählt werden. Figure 4 shows a navigation unit 30a and an indication unit 16a. The navigation unit 30a is designed as a relative navigation unit. The navigation unit 30a has four operating elements 32a, 34a, 36a, 38a designed as touch-sensitive operating surfaces, that is to say operating surfaces with capacitive sensors.
