The expression that a straight line and / or plane is oriented “at least substantially perpendicularly” to a further straight line and / or plane which is separate from the one straight line and / or plane is to be understood in particular to mean that the straight line and / or Plane with the further straight line and / or plane when projecting onto at least one projection plane, in which at least one of the straight lines and / or one of the planes is arranged, encloses an angle which is preferably less than 15 °, advantageously less than 10 ° and in particular deviates by less than 5 ° from an angle of 90 °. Alternatively or additionally, it is conceivable that at least some of the heating elements form a classic hob. It is also conceivable that part, in particular essentially 50%, of a cooking surface is designed as a classic hob and a further part, in particular essentially 50%, of the cooking surface is designed as a variable cooking surface area. This enables a high degree of flexibility to be achieved.

In einer weiteren nicht beanspruchten Ausgestaltung wird vorgeschlagen, dass die den variablen Kochflächenbereich ausbildenden Heizelemente in Form einer Kochfeldmatrix angeordnet sind. Unter einer "Kochfeldmatrix" soll insbesondere eine Anordnung von Heizelementen verstanden werden, bei der die Heizelemente in einer Einbaulage, vorteilhaft in einer Schwerkraftrichtung unterhalb des Grundkörpers, in einem regelmäßigen Raster, insbesondere in Form von Zeilen und/oder Spalten, angeordnet sind, wobei insbesondere mindestens drei der Heizelemente in einer Zeile und insbesondere mindestens drei der Heizelemente in einer Spalte angeordnet sind. Ein mittels der in Form einer Kochfeldmatrix angeordneten Heizelemente heizbarer Bereich, insbesondere eine Kochfläche, umfasst insbesondere mindestens 60 %, vorteilhaft mindestens 70 % besonders vorteilhaft mindestens 80 % und vorzugsweise mindestens 90 % einer Gesamtfläche des heizbaren Bereichs. Dadurch kann insbesondere ein hohes Maß an Flexibilität erreicht werden.In a further embodiment, which is not claimed, it is proposed that the heating elements forming the variable cooking surface area are arranged in the form of a hob matrix. A "hob matrix" is to be understood in particular to mean an arrangement of heating elements in which the heating elements are arranged in a mounting position, advantageously in a direction of gravity below the base body, in a regular grid, in particular in the form of rows and / or columns, in particular at least three of the heating elements are arranged in a row and in particular at least three of the heating elements in a column. A region which can be heated by means of the heating elements arranged in the form of a hob matrix, in particular a cooking surface, comprises in particular at least 60%, advantageously at least 70%, particularly advantageously at least 80% and preferably at least 90% of a total surface of the heatable region. This enables a high degree of flexibility to be achieved.

Zudem wird vorgeschlagen, dass zumindest ein Teil der Heizelemente ein klassisches Kochfeld ausbildet. Insbesondere bilden zumindest zwei, insbesondere zumindest drei, vorteilhaft zumindest vier der Heizelemente ein klassisches Kochfeld aus. Unter einem "klassischen Kochfeld" soll insbesondere eine Kochfläche verstanden werden, bei welcher Heizzonen, die jeweils durch zumindest ein Heizelement gebildet sind, fest vorgegeben sind. Beispielsweise könnten die fest vorgegebenen Heizzonen durch Markierungen auf der Kochfläche einem Bediener angezeigt werden. Insbesondere sind die Heizzonen beabstandet zueinander auf der Kochfläche angeordnet. Insbesondere weisen die Heizzonen einen Abstand zueinander auf, der größer ist als 15 %, insbesondere größer als 30 %, vorteilhaft größer als 40 %, bevorzugt größer als 50 %, besonders bevorzugt größer als 75 %, eines Betrags zumindest einer Erstreckung zumindest einer Heizzone. Dadurch kann insbesondere eine preiswerte Ausgestaltung erreicht werden.It is also proposed that at least some of the heating elements form a classic hob. In particular, at least two, in particular at least three, advantageously at least four of the heating elements form a classic hob. A “classic hob” is to be understood in particular as a cooking surface in which heating zones, which are each formed by at least one heating element, are fixed. For example, the fixed heating zones could be marked the cooking surface is displayed to an operator. In particular, the heating zones are arranged at a distance from one another on the cooking surface. In particular, the heating zones are at a distance from one another which is greater than 15%, in particular greater than 30%, advantageously greater than 40%, preferably greater than 50%, particularly preferably greater than 75%, of an amount of at least one extension of at least one heating zone. In this way, an inexpensive configuration can be achieved in particular.

Fig. 1 zeigt ein erfindungsgemäßes Kochfeld 28a, das als ein Induktionskochfeld ausgebildet ist, mit einer erfindungsgemäßen Kochfeldvorrichtung 10a, die als eine Induktionskochfeldvorrichtung ausgebildet ist. Die Kochfeldvorrichtung 10a weist einen Grundkörper 30a zu einem Aufstellen von Gargeschirren 14a auf. Der Grundkörper 30a bildet eine Kochfläche aus. Die Kochfeldvorrichtung 10a umfasst acht Heizelemente 12a zu einem Erhitzen von aufgestelltem Gargeschirr 14a. In Fig. 1 bis 4 ist der Übersichtlichkeit halber jeweils nur eines der Heizelemente 12a mit einem Bezugszeichen versehen. Die Heizelemente 12a, die als Induktionsheizelemente ausgebildet sind, sind unterhalb des Grundkörpers 30a angeordnet. Die Heizelemente 12a sind jeweils dazu vorgesehen, auf dem Grundkörper 30a oberhalb der Heizelemente 12a aufgestelltes Gargeschirr 14a zu erhitzen. Die Heizelemente 12a sind als längliche Heizelemente 12a ausgebildet. Jedes Heizelement 12a weist eine Längserstreckung 32a auf, die größer ist als eine Quererstreckung 34a des Heizelements 12a. Fig. 1 shows an inventive hob 28a, which is designed as an induction hob, with an inventive hob device 10a, which is designed as an induction hob device. The hob device 10a has a base body 30a for setting up cooking utensils 14a. The base body 30a forms a cooking surface. The hob device 10a comprises eight heating elements 12a for heating cookware 14a that has been set up. In 1 to 4 only one of the heating elements 12a is provided with a reference symbol for the sake of clarity. The heating elements 12a, which are designed as induction heating elements, are arranged below the base body 30a. The heating elements 12a are each intended to heat cookware 14a placed on the base body 30a above the heating elements 12a. The heating elements 12a are designed as elongated heating elements 12a. Each heating element 12a has a longitudinal extent 32a, which is larger than a transverse extent 34a of the heating element 12a.

Jeweils vier der Heizelemente 12a bilden einen variablen Kochflächenbereich 24a aus. Die beiden variablen Kochflächenbereiche 24a sind nebeneinander angeordnet. Ein erster der variablen Kochflächenbereiche 24a ist auf einer ersten Seite des Grundkörpers 30a angeordnet. Ein zweiter der variablen Kochflächenbereiche 24a ist auf einer zweiten Seite des Grundkörpers 30a, die der ersten Seite gegenüberliegt, angeordnet. Die die variablen Kochflächenbereiche 24a ausbildenden Heizelemente 12a sind jeweils in einer einzelnen Reihe angeordnet. Die die einzelne Reihe ausbildenden Heizelemente 12a sind bezüglich einer Reihenlängsrichtung 36a benachbart angeordnet. Die Reihenlängsrichtung 36a ist im Wesentlichen senkrecht zu der Längserstreckung 32a der Heizelemente 12a ausgerichtet. Die Reihenlängsrichtung 36a erstreckt sich ausgehend von einem in eingebautem Zustand einem Bediener zugewandten Bereich des Grundkörpers 30a in Richtung eines in eingebautem Zustand einem Bediener abgewandten Bereichs des Grundkörpers 30a. Die die einzelne Reihe ausbildenden Heizelemente 12a weisen bezüglich der Reihenlängsrichtung 36a einen Abstand auf, der wesentlich kleiner ist als die im Wesentlichen parallel zu der Reihenlängsrichtung 36a ausgerichtete Quererstreckung 34a der Heizelemente 12a.Four of the heating elements 12a each form a variable cooking surface area 24a. The two variable cooking surface areas 24a are arranged side by side. A first of the variable cooking surface areas 24a is arranged on a first side of the base body 30a. A second of the variable cooking surface areas 24a is on a second side of the base body 30a, which is opposite to the first side. The the variable Heating elements 12a forming cooking surface areas 24a are each arranged in a single row. The heating elements 12a forming the single row are arranged adjacent to one another with respect to a row longitudinal direction 36a. The row longitudinal direction 36a is aligned essentially perpendicular to the longitudinal extent 32a of the heating elements 12a. The row longitudinal direction 36a extends from a region of the base body 30a facing an operator in the installed state in the direction of a region of the base body 30a facing away from an operator in the installed state. The heating elements 12a forming the individual row are at a distance with respect to the row longitudinal direction 36a which is significantly smaller than the transverse extension 34a of the heating elements 12a, which is essentially parallel to the row longitudinal direction 36a.

Die Kochfeldvorrichtung 10a umfasst eine Sensoreinheit zu einer Detektion von aufgestelltem Gargeschirr 14a. Die Sensoreinheit ist im Wesentlichen einstückig mit den Heizelementen 12a ausgebildet und dazu vorgesehen, mittels Messung zumindest einer Induktivität aufgestelltes Gargeschirr 14a zu detektieren. Die Kochfeldvorrichtung 10a umfasst eine Steuereinheit 16a zu einer Steuerung und Regelung der Heizelemente 12a. Die Steuereinheit 16a ist mit der Sensoreinheit verbunden. Die Steuereinheit 16a und die Sensoreinheit sind elektrisch verbunden. Die Steuereinheit 16a ist dazu vorgesehen, in Abhängigkeit einer Detektion von aufgestelltem Gargeschirr 14a durch die Sensoreinheit von aufgestelltem Gargeschirr 14a bedeckte Heizelemente 12a zu Heizzonen zusammenzufassen. Die Steuereinheit 16a ist dazu vorgesehen, die zu Heizzonen zusammengefassten Heizelemente 12a zu betreiben.The cooktop device 10a comprises a sensor unit for detecting cookware 14a that has been set up. The sensor unit is essentially formed in one piece with the heating elements 12a and is intended to detect cookware 14a set up by measuring at least one inductance. The cooktop device 10a comprises a control unit 16a for controlling and regulating the heating elements 12a. The control unit 16a is connected to the sensor unit. The control unit 16a and the sensor unit are electrically connected. The control unit 16a is provided to combine heating elements 12a covered by the sensor unit of the cookware 14a that has been set up, as a function of a detection of the cookware 14a that has been set up, to form heating zones. The control unit 16a is provided to operate the heating elements 12a combined into heating zones.

In einem Verfahren zum Betrieb der Kochfeldvorrichtung 10a detektiert die Sensoreinheit eine erste Position 18a eines aufgestellten Gargeschirrs 14a. Die Steuereinheit 16a aktiviert der ersten Position 18a des Gargeschirrs 14a zugeordnete Heizelemente 12a. Bedeckt beispielsweise ein aufgestelltes Gargeschirr 14a ein einzelnes Heizelement 12a - wie dies in Fig. 1 dargestellt ist - so aktiviert die Steuereinheit 16a das der ersten Position 18a des aufgestellten Gargeschirrs 14a zugeordnete Heizelement 12a. Für den Fall einer Änderung von der ersten Position 18a des Gargeschirrs 14a zu einer zweiten Position 20a des Gargeschirrs 14a deaktiviert die Steuereinheit 16a ein der ersten Position 18a des Gargeschirrs 14a zugeordnetes erstes Heizelement 12a. Zudem aktiviert die Steuereinheit 16 ein der zweiten Position 20a des Gargeschirrs 14a zugeordnetes zweites Heizelement 12a mit unterschiedlicher Heizleistungsdichte als das erste Heizelement 12a (vgl. Fig. 2).In a method for operating the cooktop device 10a, the sensor unit detects a first position 18a of a set of cookware 14a. The control unit 16a activates heating elements 12a assigned to the first position 18a of the cookware 14a. For example, a set of cookware 14a covers a single heating element 12a - as shown in FIG Fig. 1 the control unit 16a activates the heating element 12a assigned to the first position 18a of the cookware 14a set up. In the event of a change from the first position 18a of the cookware 14a to a second position 20a of the cookware 14a, the control unit 16a deactivates a first heating element 12a assigned to the first position 18a of the cookware 14a. In addition, the control unit 16 activates one assigned to the second position 20a of the cookware 14a second heating element 12a with a different heating power density than the first heating element 12a (cf. Fig. 2 ).

Detektiert die Sensoreinheit eine erste Position 18a eines aufgestellten Gargeschirrs 38a, das zwei Heizelementen 12a zuzuordnen ist (vgl. Fig. 1), so aktiviert die Steuereinheit 16a der ersten Position 18a des Gargeschirrs 38a zugeordnete Heizelemente 12a. Für den Fall einer Änderung von der ersten Position 18a des Gargeschirrs 38a zu einer zweiten Position 20a des Gargeschirrs 38a deaktiviert die Steuereinheit 16a ein der ersten Position 18a des Gargeschirrs 38a zugeordnetes erstes der Heizelemente 12a, das in der ersten Position 18a des Gargeschirrs 38a von dem Gargeschirr 38a bedeckt ist und in der zweiten Position 20a des Gargeschirrs 38a unbedeckt ist. Zudem aktiviert die Steuereinheit 16a ein der zweiten Position 20a des Gargeschirrs 38a zugeordnetes zweites Heizelement 12a, das in der ersten Position 18a des Gargeschirrs 38a unbedeckt und in der zweiten Position 20a des Gargeschirrs 38a von dem Gargeschirr 38a bedeckt ist, mit unterschiedlicher Heizleistungsdichte als das erste Heizelement 12a (vgl. Fig. 2). Für den Fall einer Änderung von der ersten Position 18a des Gargeschirrs 38a zu einer zweiten Position 20a des Gargeschirrs 38a reaktiviert die Steuereinheit 16a ein Heizelement 12a, das sich in aktiviertem Zustand befindet und das in der ersten Position 18a des Gargeschirrs 38a und der zweiten Position 20a des Gargeschirrs 38a von dem Gargeschirr 38a bedeckt ist, mit veränderter unterschiedlicher Heizleistungsdichte. Ein Fall, in welchem ein aufgestelltes Gargeschirr mehr als zwei Heizelemente bedeckt, verläuft analog hierzu.If the sensor unit detects a first position 18a of a set of cookware 38a which is to be assigned to two heating elements 12a (cf. Fig. 1 ), the control unit 16a activates heating elements 12a associated with the first position 18a of the cookware 38a. In the event of a change from the first position 18a of the cookware 38a to a second position 20a of the cookware 38a, the control unit 16a deactivates a first of the heating elements 12a associated with the first position 18a of the cookware 38a, which is in the first position 18a of the cookware 38a Cookware 38a is covered and is uncovered in the second position 20a of the cookware 38a. In addition, the control unit 16a activates a second heating element 12a assigned to the second position 20a of the cooking utensil 38a, which is uncovered in the first position 18a of the cooking utensil 38a and is covered by the cooking utensil 38a in the second position 20a of the cooking utensil 38a, with a different heating power density than the first Heating element 12a (cf. Fig. 2 ). In the event of a change from the first position 18a of the cookware 38a to a second position 20a of the cookware 38a, the control unit 16a reactivates a heating element 12a which is in the activated state and which is in the first position 18a of the cookware 38a and the second position 20a of the cookware 38a is covered by the cookware 38a with a different heating power density. A case in which a set of cookware covers more than two heating elements is analogous to this.

Die Steuereinheit 16a betreibt ein einem aufgestellten Gargeschirr 14a, 38a zugeordnetes Heizelement 12a in Abhängigkeit einer Position 18a, 20a des Gargeschirrs 14a, 38a mit unterschiedlicher Heizleistungsdichte. Die Steuereinheit 16a betreibt die Heizelemente 12a bezüglich der Reihenlängsrichtung 36a mit unterschiedlichen Heizleistungsdichten. Hierbei betreibt die Steuereinheit 16a ein in eingebautem Zustand in einem einem Bediener zugewandten Bereich angeordnetes Heizelement 12a mit unterschiedlicher Heizleistungsdichte als ein in eingebautem Zustand in einem einem Bediener abgewandten Bereich angeordnetes Heizelement 12a. Die Steuereinheit 16a umfasst eine Speichereinheit, in welcher zu jedem Heizelement 12a in Abhängigkeit einer Position des Heizelements 12a eine Heizleistungsdichte gespeichert ist. Die Heizleistungsdichten eines Großteils der Heizelemente 12a, und zwar eines jeden der Heizelemente 12a, unterscheiden sich voneinander. Die Steuereinheit 16a betreibt in einem Betriebsmodus die Heizelemente 12a positionsabhängig mit vordefinierten, sich voneinander unterscheidenden Heizleistungsdichten. Eine vordefinierte Heizleistungsdichte eines in eingebautem Zustand in dem einem Bediener zugewandten Bereich angeordneten Heizelements 12a ist größer als eine vordefinierte Heizleistungsdichte eines in eingebautem Zustand in dem einem Bediener abgewandten Bereich angeordneten Heizelements 12a. In dem Betriebsmodus ordnet die Steuereinheit 16a einem Heizelement 12a, das in dem einem Bediener zugewandten Bereich angeordnet ist, eine höhere Heizleistungsdichte zu als einem Heizelement 12a, das in dem einem Bediener abgewandten Bereich angeordnet ist.The control unit 16a operates a heating element 12a associated with a set of cookware 14a, 38a, depending on a position 18a, 20a of the cookware 14a, 38a with a different heating power density. The control unit 16a operates the heating elements 12a with respect to the row longitudinal direction 36a with different heating power densities. In this case, the control unit 16a operates a heating element 12a arranged in an installed state in an area facing an operator with a different heating power density than a heating element 12a arranged in an installed state in an area facing away from an operator. The control unit 16a comprises a storage unit in which a heating power density is stored for each heating element 12a depending on a position of the heating element 12a. The heating power densities of a majority of the heating elements 12a, namely each of the heating elements 12a, differ from one another. The control unit 16a operates in an operating mode the heating elements 12a are position-dependent with predefined, different heating power densities. A predefined heating power density of a heating element 12a arranged in the installed state in the area facing an operator is greater than a predefined heating power density of a heating element 12a arranged in the area facing away from an operator. In the operating mode, the control unit 16a assigns a higher heating power density to a heating element 12a which is arranged in the region facing an operator than a heating element 12a which is arranged in the region facing away from an operator.

Die Kochfeldvorrichtung 10a weist in einem in eingebautem Zustand einem Bediener zuweisenden Bereich eine Bedieneinheit 22a zu einer Eingabe von Betriebsparametern auf. Beispielsweise ist die Bedieneinheit zu einer Auswahl und/oder Veränderung einer Heizzone vorgesehen. Zudem könnte die Bedieneinheit zu einer Einstellung einer Heizleistung und/oder Heizleistungsdichte einer Heizzone vorgesehen sein. Ebenfalls denkbar ist, dass die Bedieneinheit zu einer Auswahl und/oder Veränderung einer Garzeit und/oder eines Garprogramms ausgebildet ist. Weiterhin ist denkbar, dass die Bedieneinheit zu einem Wechsel eines Betriebsmodus und/oder Betriebszustands vorgesehen ist. Alternativ sind weitere, einem Fachmann als sinnvoll erscheinende Ausbildungen der Bedieneinheit und/oder des Betriebsparameters denkbar. Die Kochfeldvorrichtung 10a weist eine Steuereinheit 16a auf, die dazu vorgesehen ist, in Abhängigkeit der mittels der Bedieneinheit 22a eingegebenen Betriebsparameter Aktionen auszuführen und/oder Einstellungen zu verändern.The hob device 10a has a control unit 22a in the installed state for an operator to enter operating parameters. For example, the control unit is provided for selecting and / or changing a heating zone. In addition, the control unit could be provided for setting a heating power and / or heating power density of a heating zone. It is also conceivable that the control unit is designed to select and / or change a cooking time and / or a cooking program. It is also conceivable that the operating unit is provided for changing an operating mode and / or operating state. Alternatively, further configurations of the operating unit and / or the operating parameter that appear to be useful to a person skilled in the art are conceivable. The cooktop device 10a has a control unit 16a which is provided to carry out actions and / or to change settings as a function of the operating parameters entered by means of the operating unit 22a.

Die Steuereinheit 16a ändert in Abhängigkeit von einer Bedienereingabe mittels der Bedieneinheit 22a eine in der Speichereinheit gespeicherte, vordefinierte Heizleistungsdichte eines der Heizelemente 12a. Bei einer Änderung einer vordefinierten Heizleistungsdichte eines ersten Heizelements 12a ändert die Steuereinheit 16a in Abhängigkeit von der Änderung der vordefinierten Heizleistungsdichte des ersten Heizelements 12a Heizleistungsdichten der weiteren drei Heizelemente 12a, welche zusammen mit dem ersten Heizelement 12a den variablen Kochflächenbereich 24a ausbilden. Zudem wechselt die Steuereinheit 16a in Abhängigkeit von einer Bedieneingabe mittels der Bedieneinheit 22a zwischen dem ersten Betriebsmodus, in welchem die Heizelemente 12a positionsabhängig mit vordefinierten, sich voneinander unterscheidenden Heizleistungsdichten betrieben werden, und einem zweiten Betriebsmodus, in welchem die Heizelemente 12a mit voneinander unabhängigen Heizleistungsdichten betrieben werden. In dem ersten Betriebsmodus weist ein in dem in eingebautem Zustand einem Bediener zugewandten Bereich angeordnetes Heizelement 12a eine größte vordefinierte Heizleistungsdichte der den variablen Kochflächenbereich 24a ausbildenden Heizelemente 12a auf. Die Heizleistungsdichten der weiteren Heizelemente 12a nehmen in Richtung der Reihenlängsrichtung 36a ab. In Abhängigkeit von einer Bedieneingabe mittels der Bedieneinheit 22a ändert die Steuereinheit 16a eine Zuordnung der vordefinierten, sich voneinander unterscheidenden Heizleistungsdichten zu den einzelnen Heizelementen 12a. Nach einer Bedieneingabe mittels der Bedieneinheit 22a weist ein in dem in eingebautem Zustand einem Bediener zugewandten Bereich angeordnetes Heizelement 12a eine kleinste vordefinierte Heizleistungsdichte der den variablen Kochflächenbereich 24a ausbildenden Heizelemente 12a auf. Die Heizleistungsdichten der weiteren Heizelemente 12a nehmen in Richtung der Reihenlängsrichtung 36a zu.The control unit 16a changes a predefined heating power density of one of the heating elements 12a, which is stored in the storage unit, as a function of an operator input by means of the operating unit 22a. When a predefined heating power density of a first heating element 12a changes, the control unit 16a changes heating power densities of the further three heating elements 12a, which together with the first heating element 12a form the variable cooking surface area 24a, depending on the change in the predefined heating power density of the first heating element 12a. In addition, the control unit 16a changes as a function of an operating input by means of the operating unit 22a between the first operating mode, in which the heating elements 12a are operated in a position-dependent manner with predefined, different heating power densities, and a second one Operating mode in which the heating elements 12a are operated with independent heating power densities. In the first operating mode, a heating element 12a arranged in the area facing an operator in the installed state has a greatest predefined heating power density of the heating elements 12a forming the variable cooking surface area 24a. The heating power densities of the further heating elements 12a decrease in the direction of the row longitudinal direction 36a. Depending on an operating input by means of the operating unit 22a, the control unit 16a changes an assignment of the predefined, different heating power densities to the individual heating elements 12a. After an operating input by means of the operating unit 22a, a heating element 12a arranged in the area facing an operator in the installed state has a smallest predefined heating power density of the heating elements 12a forming the variable cooking surface area 24a. The heating power densities of the further heating elements 12a increase in the direction of the row longitudinal direction 36a.

The heating elements 12b, which are designed as induction heating elements, are arranged below a base body 30b. The heating elements 12b are designed as classic heating elements 12b. Two of the heating elements 12b are arranged one behind the other with respect to a row longitudinal direction 36b. The heating elements 12b form a classic hob 26b.

Die Kochfeldvorrichtung 10b umfasst eine Sensoreinheit zu einer Detektion von aufgestelltem Gargeschirr 14b. In einem Verfahren zum Betrieb der Kochfeldvorrichtung 10b detektiert die Sensoreinheit eine erste Position 18b eines aufgestellten Gargeschirrs 14b. Die Kochfeldvorrichtung 10b umfasst eine Steuereinheit 16b, die der ersten Position 18b des Gargeschirrs 14b zugeordnete Heizelemente 12b aktiviert. Für den Fall einer Änderung von der ersten Position 18b des Gargeschirrs 14b zu einer zweiten Position 20b des Gargeschirrs 14b deaktiviert die Steuereinheit 16b ein der ersten Position 18b des Gargeschirrs 14a zugeordnetes erstes Heizelement 12b und aktiviert ein der zweiten Position 20b des Gargeschirrs 14b zugeordnetes zweites Heizelement 12b mit unterschiedlicher Heizleistungsdichte als das erste Heizelement 12b (vgl. Fig. 4). Denkbar ist, dass - beispielsweise im Fall von mehr als vier Heizelementen, wobei drei Heizelemente bezüglich der Reihenlängsrichtung hintereinander angeordnet sind - die Steuereinheit für den Fall einer Änderung von der ersten Position des Gargeschirrs zu einer zweiten Position des Gargeschirrs ein Heizelement, das sich in aktiviertem Zustand befindet und das in der ersten Position des Gargeschirrs und der zweiten Position des Gargeschirrs von dem Gargeschirr bedeckt ist, mit veränderter unterschiedlicher Heizleistungsdichte reaktiviert.The cooktop device 10b comprises a sensor unit for detecting cookware 14b that has been set up. In a method for operating the cooktop device 10b, the sensor unit detects a first position 18b of a set of cookware 14b. The cooktop device 10b comprises a control unit 16b which activates heating elements 12b associated with the first position 18b of the cookware 14b. In the event of a change from the first position 18b of the cookware 14b to a second position 20b of the cookware 14b, the control unit 16b deactivates a first heating element 12b assigned to the first position 18b of the cookware 14a and activates a second heating element assigned to the second position 20b of the cookware 14b 12b with a different heating power density than the first heating element 12b (cf. Fig. 4 ). It is conceivable that - for example in the case of more than four heating elements, where three heating elements are arranged one behind the other with respect to the longitudinal direction of the row - the control unit, in the event of a change from the first position of the cooking utensil to a second position of the cooking utensil, a heating element which is in the activated state State and that in the first position of the cookware and the second position of the cookware is covered by the cookware, reactivated with changed different heating power density.

Die Steuereinheit 16b betreibt ein einem aufgestellten Gargeschirr 14b zugeordnetes Heizelement 12b in Abhängigkeit einer Position 18b, 20b des Gargeschirrs 14b mit unterschiedlicher Heizleistungsdichte. Die Steuereinheit 16b betreibt die Heizelemente 12b bezüglich der Reihenlängsrichtung 36b mit unterschiedlichen Heizleistungsdichten. Hierbei betreibt die Steuereinheit 16b ein in eingebautem Zustand in einem einem Bediener zugewandten Bereich angeordnetes Heizelement 12b mit unterschiedlicher Heizleistungsdichte als ein in eingebautem Zustand in einem einem Bediener abgewandten Bereich angeordnetes Heizelement 12b. Die Steuereinheit 16b umfasst eine Speichereinheit, in welcher zu jedem Heizelement 12b in Abhängigkeit einer Position des Heizelements 12b eine Heizleistungsdichte gespeichert ist. Die Heizleistungsdichten eines Großteils der Heizelemente 12b, und zwar eines jeden der Heizelemente 12b, unterscheiden sich voneinander. Die Steuereinheit 16b betreibt in einem Betriebsmodus die Heizelemente 12b positionsabhängig mit vordefinierten, sich voneinander unterscheidenden Heizleistungsdichten. In dem Betriebsmodus ordnet die Steuereinheit 16b einem Heizelement 12b, das in dem einem Bediener zugewandten Bereich angeordnet ist, eine höhere Heizleistungsdichte zu als einem Heizelement 12b, das in dem einem Bediener abgewandten Bereich angeordnet ist.The control unit 16b operates a heating element 12b assigned to a set of cookware 14b in dependence on a position 18b, 20b of the cookware 14b with different heating power density. The control unit 16b operates the heating elements 12b with respect to the row longitudinal direction 36b with different heating power densities. In this case, the control unit 16b operates a heating element 12b arranged in an installed state in an area facing an operator with different heating power density than a heating element 12b arranged in an installed state in an area facing away from an operator. The control unit 16b comprises a storage unit in which a heating power density is stored for each heating element 12b depending on a position of the heating element 12b. The heating power densities of a majority of the heating elements 12b, namely each of the heating elements 12b, differ from one another. In one operating mode, the control unit 16b operates the heating elements 12b in a position-dependent manner with predefined, differing heating power densities. In the operating mode, the control unit 16b assigns a heating element 12b to the area facing an operator is arranged, a higher heating power density than a heating element 12b, which is arranged in the area facing away from an operator.

Die Steuereinheit 16b ändert in Abhängigkeit von einer Bedienereingabe mittels einer Bedieneinheit 22b eine in der Speichereinheit gespeicherte, vordefinierte Heizleistungsdichte eines der Heizelemente 12b. Bei einer Änderung einer vordefinierten Heizleistungsdichte eines ersten Heizelements 12b ändert die Steuereinheit 16b in Abhängigkeit von der Änderung der vordefinierten Heizleistungsdichte des ersten Heizelements 12b eine Heizleistungsdichte des weiteren Heizelements 12b, welches bezüglich der Reihenlängsrichtung 36b zu dem ersten Heizelement 12b nächstgelegen angeordnet ist. In Abhängigkeit von einer Bedieneingabe mittels der Bedieneinheit 22b ändert die Steuereinheit 16b eine Zuordnung der vordefinierten, sich voneinander unterscheidenden Heizleistungsdichten zu den einzelnen Heizelementen 12b. Zudem wechselt die Steuereinheit 16b in Abhängigkeit von einer Bedieneingabe mittels der Bedieneinheit 22b zwischen dem ersten Betriebsmodus, in welchem die Heizelemente 12b positionsabhängig mit vordefinierten, sich voneinander unterscheidenden Heizleistungsdichten betrieben werden, und einem zweiten Betriebsmodus, in welchem die Heizelemente 12b mit voneinander unabhängigen Heizleistungsdichten betrieben werden.The control unit 16b changes a predefined heating power density of one of the heating elements 12b, which is stored in the storage unit, as a function of an operator input by means of an operating unit 22b. When a predefined heating power density of a first heating element 12b changes, the control unit 16b changes a heating power density of the further heating element 12b, which is arranged closest to the first heating element 12b with respect to the longitudinal direction 36b, as a function of the change in the predefined heating power density of the first heating element 12b. Depending on an operating input by means of the operating unit 22b, the control unit 16b changes an assignment of the predefined, differing heating power densities to the individual heating elements 12b. In addition, the control unit 16b changes depending on an operating input by means of the operating unit 22b between the first operating mode, in which the heating elements 12b are operated depending on the position with predefined, different heating power densities, and a second operating mode, in which the heating elements 12b are operated with independent heating power densities will.

Fig. 5 zeigt ein Kochfeld 28c mit einer Kochfeldvorrichtung 10c. Die Kochfeldvorrichtung 10c umfasst eine Vielzahl an Heizelementen 12c zu einem Erhitzen von aufgestelltem Gargeschirr 14c, 46c, 48c. In einer Einbaulage sind die Heizelemente 12c unterhalb eines Grundkörpers 30c angeordnet. Der Grundkörper 30c ist als Kochfeldplatte ausgebildet. Die Heizelemente 12c bilden einen variablen Kochflächenbereich 24c aus. Die den variablen Kochflächenbereich 24c ausbildenden Heizelemente 12c sind in Form einer Kochfeldmatrix angeordnet. Hierbei sind die Heizelemente 12c in Spalten und Zeilen angeordnet. Im vorliegenden Ausführungsbeispiel ist der Begriff "Matrix" im mathematischen Sinn zu verstehen. In einer alternativen Ausgestaltung ist denkbar, dass Spalten und/oder Zeilen einer Kochfeldmatrix versetzt zueinander angeordnet sind. In Fig. 6 bis 11 wurde auf eine Darstellung der Heizelemente 12c der Übersichtlichkeit halber verzichtet. Fig. 5 shows a hob 28c with a hob device 10c. The hob device 10c comprises a plurality of heating elements 12c for heating cookware 14c, 46c, 48c which has been set up. In an installed position, the heating elements 12c are arranged below a base body 30c. The base body 30c is designed as a hob plate. The heating elements 12c form a variable cooking surface area 24c. The heating elements 12c forming the variable cooking surface area 24c are arranged in the form of a hob matrix. Here, the heating elements 12c are arranged in columns and rows. In the present exemplary embodiment, the term “matrix” is to be understood in the mathematical sense. In an alternative embodiment, it is conceivable that columns and / or rows of a hob matrix are arranged offset from one another. In 6 to 11 the heating elements 12c have been omitted for the sake of clarity.

Die Kochfeldvorrichtung 10c umfasst eine Steuereinheit 16c, die in einem Verfahren zum Betrieb einer ersten Position 18c eines aufgestellten Gargeschirrs 14c zugeordnete erste Heizelemente 12c aktiviert (vgl. Fig. 6). Für den Fall einer Änderung von der ersten Position 18c des Gargeschirrs 14c zu einer zweiten Position 20c des Gargeschirrs 14c deaktiviert die Steuereinheit 16c zumindest ein der ersten Position 18c des Gargeschirrs 14c zugeordnetes erstes Heizelement 12c und aktiviert zumindest ein der zweiten Position 20c des Gargeschirrs 14c zugeordnetes zweites Heizelement 12c mit unterschiedlicher Heizleistungsdichte als das zumindest eine erste Heizelement 12c. Hierbei reaktiviert die Steuereinheit 16c zumindest ein Heizelement 12c, das sich in aktiviertem Zustand befindet und das in der ersten Position 18c des Gargeschirrs 14c und der zweiten Position 20c des Gargeschirrs 14c von dem Gargeschirr 14c bedeckt ist, mit veränderter unterschiedlicher Heizleistungsdichte. Ein Fall einer Änderung von der zweiten Position 20c des Gargeschirrs 14c zu einer dritten Position 42c des Gargeschirrs 14c verläuft analog zu dem Fall einer Änderung von der ersten Position 18c des Gargeschirrs 14c zu der zweiten Position 20c des Gargeschirrs 14c.The cooktop device 10c comprises a control unit 16c which, in a method for operating a first position 18c of a set of cookware 14c, activates first heating elements 12c (cf. Fig. 6 ). In the event of a change from the first Position 18c of the cookware 14c to a second position 20c of the cookware 14c, the control unit 16c deactivates at least one first heating element 12c assigned to the first position 18c of the cookware 14c and activates at least one second heating element 12c assigned to the second position 20c of the cookware 14c with a different heating power density than that at least one first heating element 12c. In this case, the control unit 16c reactivates at least one heating element 12c, which is in the activated state and which is covered by the cookware 14c in the first position 18c of the cookware 14c and the second position 20c of the cookware 14c, with a different, different heating power density. A case of a change from the second position 20c of the cookware 14c to a third position 42c of the cookware 14c is analogous to the case of a change from the first position 18c of the cookware 14c to the second position 20c of the cookware 14c.

In einem Betriebsmodus betreibt die Steuereinheit 16c einem aufgestellten Gargeschirr 14c zugeordnete Heizelemente 12c in Abhängigkeit einer Position 18c, 20c, 42c des Gargeschirrs 14c mit unterschiedlicher Heizleistungsdichte. Die Steuereinheit 16c betreibt die Heizelemente 12c in dem Betriebsmodus positionsabhängig mit vordefinierten, sich voneinander unterscheidenden Heizleistungsdichten. In dem Betriebsmodus ändert die Steuereinheit 16c die vordefinierten Heizleistungsdichten der Heizelemente 12c in Abhängigkeit von einer Bedieneingabe mittels einer Bedieneinheit 22c. In einer Speichereinheit der Steuereinheit 16c sind mehrere Konfigurationen von vordefinierten Heizleistungsdichten der Heizelemente 12c gespeichert. Bei jeder der Konfigurationen istden Heizelementen 12c in Abhängigkeit von der Position des entsprechenden Heizelements 12c eine Heizleistungsdichte zugeordnet. Zusätzlich zu den gespeicherten Konfigurationen ist denkbar, dass ein Bediener durch eine Bedieneingabe mittels der Bedieneinheit weitere Konfigurationen erstellen kann.In one operating mode, the control unit 16c operates heating elements 12c assigned to a cookware 14c that has been set up, depending on a position 18c, 20c, 42c of the cookware 14c with a different heating power density. The control unit 16c operates the heating elements 12c in the operating mode in a position-dependent manner with predefined, differing heating power densities. In the operating mode, the control unit 16c changes the predefined heating power densities of the heating elements 12c as a function of an operator input by means of an operator unit 22c. A plurality of configurations of predefined heating power densities of the heating elements 12c are stored in a storage unit of the control unit 16c. In each of the configurations, a heating power density is assigned to the heating elements 12c depending on the position of the corresponding heating element 12c. In addition to the saved configurations, it is conceivable that an operator can create further configurations by means of an operator input using the operator unit.

Die Steuereinheit 16c behält gegebene vordefinierte Heizleistungsdichten der Heizelemente 12c so lange bei, bis eine Änderung wenigstens einer Heizleistungsdichte eines der Heizelemente 12c durch eine Bedieneingabe mittels der Bedieneinheit 22c erfolgt. Beispielsweise könnte die Steuereinheit gegebene vordefinierte Heizleistungsdichten der Heizelemente 12c über eine Ruhephase hinaus beibehalten. Insbesondere könnte die Ruhephase beispielsweise durch eine Deaktivierung des Kochfelds und/oder einen Stromausfall und/oder eine Notabschaltung auftreten.The control unit 16c maintains given predefined heating power densities of the heating elements 12c until a change in at least one heating power density of one of the heating elements 12c takes place by an operating input by means of the operating unit 22c. For example, the control unit could maintain given predefined heating power densities of the heating elements 12c beyond a rest phase. In particular, the rest phase could occur, for example, due to a deactivation of the hob and / or a power failure and / or an emergency shutdown.

Gemäß einer ersten Konfiguration ordnet die Steuereinheit 16c in dem Betriebsmodus Heizelementen 12c, die in einem einem Bediener zugewandten Bereich angeordnet sind, eine höhere Heizleistungsdichte zu als Heizelementen 12c, die in einem einem Bediener abgewandten Bereich angeordnet sind (vgl. Fig. 6). Durch eine Änderung einer Position 18c, 20c, 42c des Gargeschirrs 14c in einer Tiefenrichtung 40c kann in dem Betriebsmodus eine dem Gargeschirr 14c zugeführte Heizleistungsdichte in Abhängigkeit der Position 18c, 20c, 42c des Gargeschirrs 14c reduziert werden (vgl. Fig. 6). Eine solche Änderung einer Position 18c, 20c, 42c des Gargeschirrs 14c in der Tiefenrichtung 40c könnte beispielsweise von der ersten Position 18c des Gargeschirrs 14c zu der dritten Position 42c des Gargeschirrs 14c erfolgen. Die Tiefenrichtung 40c ist in einer Einbaulage von dem einem Bediener zugewandten Bereich in Richtung des einem Bediener abgewandten Bereichs ausgerichtet.According to a first configuration, the control unit 16c in the operating mode assigns a higher heating power density to heating elements 12c arranged in an area facing an operator than heating elements 12c arranged in an area facing away from an operator (cf. Fig. 6 ). By changing a position 18c, 20c, 42c of the cookware 14c in a depth direction 40c, a heating power density supplied to the cookware 14c in the operating mode can be reduced as a function of the position 18c, 20c, 42c of the cookware 14c (cf. Fig. 6 ). Such a change in a position 18c, 20c, 42c of the cookware 14c in the depth direction 40c could, for example, take place from the first position 18c of the cookware 14c to the third position 42c of the cookware 14c. In an installed position, the depth direction 40c is oriented from the area facing an operator in the direction of the area facing away from an operator.

Für den Fall einer Änderung von einer ersten Position 18c des Gargeschirrs 14c zu einer zweiten Position 20c des Gargeschirrs 14c entgegen der Tiefenrichtung 40c, betreibt die Steuereinheit 16c ein der zweiten Position 20c des Gargeschirrs 14c zugeordnetes Heizelement 12c mit höherer Heizleistungsdichte als ein der ersten Position 18c des Gargeschirrs 14c zugeordnetes Heizelement 12c (vgl. Fig. 7). Bei einer Änderung von der ersten Position 18c des Gargeschirrs 14c zu einer dritten Position 42c des Gargeschirrs 14c betreibt die Steuereinheit 16c ein der ersten Position 18c des Gargeschirrs 14c zugeordnetes Heizelement 12c mit höherer Heizleistungsdichte als ein der dritten Position 42c des Gargeschirrs 14c zugeordnetes Heizelement 12c. Ausgehend von der ersten Position 18c des Gargeschirrs 14c ist die dritte Position 42c des Gargeschirrs 14c in einer Richtung angeordnet, welche schräg zu der Tiefenrichtung 40c ausgerichtet sowie auf den einem Bediener abgewandten Bereich zugerichtet ist.In the event of a change from a first position 18c of the cooking utensil 14c to a second position 20c of the cooking utensil 14c opposite the depth direction 40c, the control unit 16c operates a heating element 12c associated with the second position 20c of the cooking utensil 14c with a higher heating power density than one of the first position 18c the heating element 12c assigned to the cookware 14c (cf. Fig. 7 ). When changing from the first position 18c of the cookware 14c to a third position 42c of the cookware 14c, the control unit 16c operates a heating element 12c assigned to the first position 18c of the cookware 14c with a higher heating power density than a heating element 12c assigned to the third position 42c of the cookware 14c. Starting from the first position 18c of the cooking utensil 14c, the third position 42c of the cooking utensil 14c is arranged in a direction which is oriented obliquely to the depth direction 40c and is directed toward the region facing away from an operator.

Wird beispielsweise ein zweites Gargeschirr 46c benachbart zu der dritten Position 42c des Gargeschirrs 14c aufgestellt, so betreibt die Steuereinheit 16c in dem Betriebsmodus ein Heizelement 12c, das dem zweiten Gargeschirr 46c zugeordnet ist, mit im Wesentlichen gleicher Heizleistungsdichte wie ein Heizelement 12c, das dem an der dritten Position 42c des Gargeschirrs 14c aufgestellten Gargeschirr 14c zugeordnet ist (vgl. Fig. 7). Beispielsweise wird ein drittes Gargeschirr 48c auf im Wesentlichen gleicher Höhe wie die zweite Position 20c des Gargeschirrs 14c aufgestellt. Das dritte Gargeschirr 48c ist bezüglich einer Orthogonalrichtung 44c zu der zweiten Position 20c des Gargeschirrs 14c benachbart angeordnet. Ein Abstand des dritten Gargeschirrs 48c von einer Vorderkante des Grundkörpers 30c ist im Wesentlichen gleich einem Abstand der zweiten Position 20c des Gargeschirrs 14c von der Vorderkante des Grundkörpers 30c. In dem Betriebsmodus betreibt die Steuereinheit 16c ein Heizelement 12c, das dem dritten Gargeschirr 14c zugeordnet ist, mit im Wesentlichen gleicher Heizleistungsdichte wie ein Heizelement 12c, das dem an der zweiten Position 20c des Gargeschirrs 14c aufgestellten Gargeschirr 14c zugeordnet ist.If, for example, a second cookware 46c is set up adjacent to the third position 42c of the cookware 14c, the control unit 16c in the operating mode operates a heating element 12c, which is assigned to the second cookware 46c, with essentially the same heating power density as a heating element 12c, which is switched on the third position 42c of the cookware 14c is set up cookware 14c (cf. Fig. 7 ). For example, a third cookware 48c is set up at substantially the same height as the second position 20c of the cookware 14c. The third cookware 48c is arranged adjacent to the second position 20c of the cookware 14c with respect to an orthogonal direction 44c. A distance of the third cookware 48c from a front edge of the base body 30c is substantially equal to a distance of the second position 20c of the cookware 14c from the front edge of the base body 30c. In the operating mode, the control unit 16c operates a heating element 12c, which is assigned to the third cookware 14c, with essentially the same heating power density as a heating element 12c, which is assigned to the cookware 14c set up at the second position 20c of the cookware 14c.

Beispielsweise ändert ein Bediener in dem Betriebsmodus durch eine Bedieneingabe mittels der Bedieneinheit 22c die vordefinierten Heizleistungsdichten der Heizelemente 12c und wählt eine zweite Konfiguration aus. Die Steuereinheit 16c ordnet in dem Betriebsmodus den Heizelementen 12c in einer Schrägrichtung, die mit der Tiefenrichtung 40c einen Winkel zwischen 10° und 80° einschließt, unterschiedliche Heizleistungsdichten zu (vgl. Fig. 8). Im vorliegenden Ausführungsbeispiel ordnet die Steuereinheit 16c in dem Betriebsmodus einem ersten Heizelement 12c, das in dem einem Bediener zugewandten Bereich in einer Ecke des Kochflächenbereichs 24c angeordnet ist, eine höchste Heizleistungsdichte zu. Heizelementen 12c, die in der Tiefenrichtung 40c zu dem ersten Heizelement 12c beabstandet sind, ordnet die Steuereinheit 16c in dem Betriebsmodus geringere Heizleistungsdichten zu als dem ersten Heizelement 12c. In dem Betriebsmodus ordnet die Steuereinheit 16c Heizelementen 12c, die in einer Orthogonalrichtung 44c zu dem ersten Heizelement 12c beabstandet sind, geringere Heizleistungsdichten zu als dem ersten Heizelement 12c. Die Orthogonalrichtung 44c ist senkrecht zu der Tiefenrichtung 40c ausgerichtet.For example, in the operating mode, an operator changes the predefined heating power densities of the heating elements 12c by an operating input by means of the operating unit 22c and selects a second configuration. In the operating mode, the control unit 16c assigns different heating power densities to the heating elements 12c in an oblique direction, which includes an angle between 10 ° and 80 ° with the depth direction 40c (cf. Fig. 8 ). In the present exemplary embodiment, the control unit 16c assigns a maximum heating power density to a first heating element 12c, which is arranged in the area facing an operator in a corner of the cooking surface area 24c. In the operating mode, the control unit 16c assigns heating elements 12c, which are spaced in the depth direction 40c to the first heating element 12c, lower heating power densities than the first heating element 12c. In the operating mode, the control unit 16c assigns heating elements 12c, which are spaced in an orthogonal direction 44c to the first heating element 12c, lower heating power densities than the first heating element 12c. The orthogonal direction 44c is aligned perpendicular to the depth direction 40c.

Beispielsweise ist ein Gargeschirr 14c in einem Nahbereich des ersten Heizelements 12c, welches in dem einem Bediener zugewandten Bereich in einer Ecke des Kochflächenbereichs 24c angeordnet ist, an einer ersten Position 18c des Gargeschirrs 14c aufgestellt. Für den Fall einer Änderung von der ersten Position 18c des Gargeschirrs 14c zu einer zweiten Position 20c des Gargeschirrs 14c in einer ersten Schrägrichtung, die mit der Tiefenrichtung 40c einen Winkel von im Wesentlichen 40° einschließt, betreibt die Steuereinheit 16c ein der ersten Position 18c des Gargeschirrs 14c zugeordnetes Heizelement 12c mit höherer Heizleistungsdichte als ein der zweiten Position 20c des Gargeschirrs 14c zugeordnetes Heizelement 12c (vgl. Fig. 8). Bei einer Änderung von der zweiten Position 20c des Gargeschirrs 14c zu einer dritten Position 42c des Gargeschirrs 14c in einer zweiten Schrägrichtung, die mit der Tiefenrichtung 40c einen Winkel von im Wesentlichen 55° einschließt, betreibt die Steuereinheit 16c ein der zweiten Position 20c des Gargeschirrs 14c zugeordnetes Heizelement 12c mit höherer Heizleistungsdichte als ein der dritten Position 42c des Gargeschirrs 14c zugeordnetes Heizelement 12c.For example, a cookware 14c is set up in a vicinity of the first heating element 12c, which is arranged in the area facing a user in a corner of the cooking surface area 24c, at a first position 18c of the cookware 14c. In the event of a change from the first position 18c of the cooking utensil 14c to a second position 20c of the cooking utensil 14c in a first oblique direction, which includes an angle of substantially 40 ° with the depth direction 40c, the control unit 16c operates one of the first position 18c des Cooking element 14c assigned to cooking utensil 12c with a higher heating power density than a heating element 12c assigned to second position 20c of cooking utensil 14c (cf. Fig. 8 ). When changing from the second position 20c of the cooking utensil 14c to a third position 42c of the cooking utensil 14c in a second oblique direction, which includes an angle of substantially 55 ° with the depth direction 40c, the control unit 16c operates in the second position 20c the heating element 12c assigned to the cooking utensil 14c with a higher heating power density than a heating element 12c assigned to the third position 42c of the cooking utensil 14c.

In Anhängigkeit einer Bedieneingabe mittels der Bedieneinheit 22c, durch welche ein Bediener eine weitere Konfiguration auswählt, ändert die Steuereinheit 16c in dem Betriebsmodus die vordefinierten Heizleistungsdichten der Heizelemente 12c. Beispielsweise ordnet die Steuereinheit 16c in dem Betriebsmodus Heizelementen 12c, die in einem ersten seitlichen Bereich des variablen Kochflächenbereichs 24c angeordnet sind, höhere Heizleistungsdichten zu als Heizelementen 12c, die in einem zweiten seitlichen Bereich des variablen Kochflächenbereichs 24c angeordnet sind (vgl. Fig. 9). Der erste Bereich des variablen Kochflächenbereichs 24c und der zweite Bereich des variablen Kochflächenbereichs 24c sind einander gegenüberliegend angeordnet. Der zweite Bereich des variablen Kochflächenbereichs 24c ist in der Orthogonalrichtung 44c zu dem ersten Bereich des variablen Kochflächenbereichs 24c beabstandet angeordnet. In dem Betriebsmodus betreibt die Steuereinheit 16c ein zweites Heizelement 12c, das in der Orthogonalrichtung 44c einen größeren Abstand zu dem ersten seitlichen Bereich des variablen Kochflächenbereichs 24c aufweist als ein erstes Heizelement 12c, mit einer geringeren Heizleistungsdichte als das erste Heizelement 12c.Depending on an operating input by means of the operating unit 22c, by means of which an operator selects a further configuration, the control unit 16c changes the predefined heating power densities of the heating elements 12c in the operating mode. For example, in the operating mode, the control unit 16c assigns higher heating power densities to heating elements 12c which are arranged in a first lateral area of the variable cooking area area 24c than heating elements 12c which are arranged in a second lateral area of the variable cooking area area 24c (cf. Fig. 9 ). The first area of the variable cooktop area 24c and the second area of the variable cooktop area 24c are arranged opposite one another. The second area of the variable cooking surface area 24c is arranged in the orthogonal direction 44c at a distance from the first area of the variable cooking area area 24c. In the operating mode, the control unit 16c operates a second heating element 12c, which in the orthogonal direction 44c is at a greater distance from the first lateral region of the variable cooking surface region 24c than a first heating element 12c, with a lower heating power density than the first heating element 12c.

Ändert ein Bediener durch eine Bedieneingabe mittels der Bedieneinheit 22c in dem Betriebsmodus die vordefinierten Heizleistungsdichten der Heizelemente 12c, indem der Bediener beispielsweise eine weitere Konfiguration auswählt, so betreibt die Steuereinheit 16c die Heizelemente 12c in Abhängigkeit der Bedieneingabe mittels der Bedieneinheit 22c positionsabhängig mit vordefinierten, sich voneinander unterscheidenden Heizleistungsdichten. Beispielsweise ordnet die Steuereinheit 16c in dem Betriebsmodus einem Heizelement 12c, das im Wesentlichen in einem Zentrum des variablen Kochflächenbereichs 24c angeordnet ist, eine höhere Heizleistungsdichte zu als Heizelementen 12c, die innerhalb von konzentrischen Bahnen um das im Wesentlichen in dem Zentrum des variablen Kochflächenbereichs 24c angeordnete Heizelement 12c angeordnet sind (vgl. Fig. 10). In dem Betriebsmodus ordnet die Steuereinheit 16c dem im Wesentlichen in dem Zentrum des variablen Kochflächenbereichs 24c angeordneten Heizelement 12c eine höchste Heizleistungsdichte zu. Die Steuereinheit 16c ordnet in dem Betriebszustand Heizelementen 12c, die innerhalb einer ersten konzentrischen Bahn um das im Wesentlichen in dem Zentrum des variablen Kochflächenbereichs 24c angeordnete Heizelement 12c angeordnet sind, dieselbe Heizleistungsdichte zu wie dem im Wesentlichen in dem Zentrum des variablen Kochflächenbereichs 24c angeordneten Heizelement 12c. Im vorliegenden Ausführungsbeispiel wählt die Steuereinheit 16c einen Radius der ersten konzentrischen Bahn in einem Bereich eines Durchmessers des Gargeschirrs 14c, das auf dem im Wesentlichen in dem Zentrum des variablen Kochflächenbereichs 24c angeordneten Heizelement 12c aufgestellt ist (vgl. Fig. 10). Die Steuereinheit 16c ordnet in dem Betriebsmodus Heizelementen 12c, die in einem Bereich zwischen der ersten konzentrischen Bahn und einer zweiten konzentrischen Bahn, die zu der ersten konzentrischen Bahn direkt benachbart ist, angeordnet sind, eine geringere Heizleistungsdichte zu als innerhalb der ersten konzentrischen Bahn angeordneten Heizelementen 12c. In dem Betriebsmodus ordnet die Steuereinheit 16c einem Heizelement 12c, das zwischen zwei konzentrischen Bahnen angeordnet ist, die von dem im Wesentlichen in dem Zentrum des variablen Kochflächenbereichs 24c angeordneten Heizelement 12c einen kleineren Abstand aufweisen als ein Heizelement 12c, das zwischen zwei weiteren konzentrischen Bahnen angeordnet ist, eine größere Heizleistungsdichte zu als dem Heizelement 12c, das zwischen den zwei weiteren konzentrischen Bahnen angeordnet ist.If an operator changes the predefined heating power densities of the heating elements 12c in the operating mode by means of an operating input by means of the operating unit 22c, for example by the operator selecting a further configuration, the control unit 16c operates the heating elements 12c as a function of the operating input by means of the operating unit 22c with position-dependent, predefined ones different heating power densities. For example, in the operating mode, the control unit 16c assigns a higher heating power density to a heating element 12c, which is arranged essentially in a center of the variable cooking surface area 24c, than heating elements 12c, which are arranged within concentric paths around what is essentially arranged in the center of the variable cooking surface area 24c Heating element 12c are arranged (cf. Fig. 10 ). In the operating mode, the control unit 16c assigns a maximum heating power density to the heating element 12c which is arranged essentially in the center of the variable cooking surface area 24c. In the operating state, the control unit 16c assigns the same heating power density as that to heating elements 12c which are arranged within a first concentric path around the heating element 12c arranged essentially in the center of the variable cooking surface area 24c heating element 12c arranged essentially in the center of the variable cooking surface area 24c. In the present exemplary embodiment, the control unit 16c selects a radius of the first concentric path in a region of a diameter of the cookware 14c, which is set up on the heating element 12c arranged essentially in the center of the variable cooking surface region 24c (cf. Fig. 10 ). In the operating mode, the control unit 16c assigns a lower heating power density to heating elements 12c which are arranged in a region between the first concentric path and a second concentric path which is directly adjacent to the first concentric path, than heating elements arranged within the first concentric path 12c. In the operating mode, the control unit 16c assigns a heating element 12c which is arranged between two concentric tracks which are at a smaller distance from the heating element 12c which is essentially arranged in the center of the variable cooking surface area 24c than a heating element 12c which is arranged between two further concentric tracks is a greater heating power density than the heating element 12c, which is arranged between the two further concentric tracks.

In einem weiteren Fall wählt ein Bediener durch eine Bedieneingabe mittels der Bedieneinheit 22c eine weitere Konfiguration der in der Speichereinheit der Steuereinheit 16c gespeicherten Konfigurationen aus. Die Steuereinheit 16c ordnet in dem Betriebsmodus Heizelementen 12c, die teilweise von einem Gargeschirr 14c bedeckt sind, eine höhere Heizleistungsdichte zu als Heizelementen 12c, die innerhalb von konzentrischen Bahnen um die von dem Gargeschirr 14c teilweise bedeckten Heizelemente 12c angeordnet sind. Hierbei kann das Gargeschirr 14c an einer beliebigen Position 18c, 20c, 42c aufgestellt sein. Beim Aufstellen eines zweiten Gargeschirrs 46c zwischen einer ersten konzentrischen Bahn um das Gargeschirr 14c und einer zweiten konzentrischen Bahn, die direkt benachbart zu der ersten konzentrischen Bahn angeordnet ist, ordnet die Steuereinheit 16c Heizelementen 12c, die teilweise von dem zweiten Gargeschirr 46c bedeckt sind, eine geringere Heizleistungsdichte zu als Heizelementen 12c, die von dem Gargeschirr 14c teilweise bedeckt und insbesondere innerhalb der ersten konzentrischen Bahn angeordnet sind. In dem Betriebsmodus ordnet die Steuereinheit 16c Heizelementen 12c, die von einem dritten Gargeschirr 48c, das zwischen der zweiten konzentrischen Bahn um das Gargeschirr 14c und einer dritten konzentrischen Bahn, die direkt benachbart zu der zweiten konzentrischen Bahn angeordnet ist, teilweise bedeckt sind, eine geringere Heizleistungsdichte zu als Heizelementen 12c, die zwischen der ersten konzentrischen Bahn und der zweiten konzentrischen Bahn angeordnet sind.In a further case, an operator selects a further configuration of the configurations stored in the memory unit of the control unit 16c by means of an operating input by means of the operating unit 22c. In the operating mode, the control unit 16c assigns a higher heating power density to heating elements 12c, which are partially covered by a cooking utensil 14c, than heating elements 12c, which are arranged within concentric paths around the heating elements 12c partially covered by the cooking utensils 14c. Here, the cookware 14c can be set up at any position 18c, 20c, 42c. When setting up a second cookware 46c between a first concentric path around the cookware 14c and a second concentric path which is arranged directly adjacent to the first concentric path, the control unit 16c arranges one of the heating elements 12c, which are partially covered by the second cookware 46c lower heating power density than heating elements 12c, which are partially covered by the cookware 14c and are arranged in particular within the first concentric path. In the operating mode, the control unit 16c arranges heating elements 12c, that of a third cookware 48c, that between the second concentric path around the cookware 14c and a third concentric path that is directly adjacent to the second concentric path is partially covered, a lower heating power density than heating elements 12c, which are arranged between the first concentric path and the second concentric path.
