In particular, the control unit is provided to initiate a single measurement upon actuation, in particular a touch, of a free area, that is to say not covered by a visualized cooking utensil. Alternatively, other input units, in particular keypads and / or rotary switches, are known. In particular, a simple control of the sensor unit and / or a user-friendly operation can be achieved.

Weiterhin wird vorgeschlagen, dass die Steuereinheit dazu vorgesehen ist, in zumindest einem Betriebsmodus die Sensorkenngröße zumindest über eine bestimmte Wartezeit hinaus zu speichern. Unter einer "Wartezeit" soll insbesondere eine Zeitdauer verstanden werden, die seit einer letzten Bedieneranfrage verstrichen ist, während keine Heizzone des variablen Kochbereichs beheizt wird. Die bestimmte Wartezeit beträgt insbesondere zumindest 1 Minute, vorteilhaft zumindest 3 Minuten, besonders vorteilhaft zumindest 4 Minuten, und insbesondere maximal 10 Minuten, vorteilhaft maximal 8 Minuten, vorzugsweise maximal 6 Minuten. Insbesondere ist die Steuereinheit dazu vorgesehen, bei Überschreiten der bestimmten Wartezeit zumindest die Anzeigeeinheit, insbesondere auch sich selbst, in einen Ruhemodus zu versetzen. Unter einem "Ruhemodus" soll insbesondere ein Betriebsmodus mit verringertem Energieverbrauch, insbesondere mit deaktivierter Anzeigeeinheit und/oder deaktivierter Recheneinheit, verstanden werden. Insbesondere ist die Steuereinheit dazu vorgesehen, nach einer Rückkehr aus dem Ruhemodus die zumindest eine detektierte und abgespeicherte Geometriekenngröße erneut auf der Anzeigeeinheit zu visualisieren. Es kann insbesondere eine Energieersparnis und/oder eine Zeitersparnis erreicht werden.Furthermore, it is proposed that the control unit be provided to store the sensor parameter in at least one operating mode at least over a certain waiting time. A "waiting time" is to be understood in particular a time period which has elapsed since a last operator request, while no heating zone of the variable cooking area is heated. The specific waiting time is in particular at least 1 minute, advantageously at least 3 minutes, particularly advantageously at least 4 minutes, and in particular at most 10 minutes, advantageously at most 8 minutes, preferably at most 6 minutes. In particular, the control unit is provided, when the specific waiting time is exceeded, at least the display unit, in particular also to put oneself in a sleep mode. A "sleep mode" is to be understood in particular as an operating mode with reduced energy consumption, in particular with deactivated display unit and / or deactivated computing unit. In particular, the control unit is provided to visualize the at least one detected and stored geometry parameter again on the display unit after a return from the idle mode. In particular, energy savings and / or time savings can be achieved.

Weiterhin wird vorgeschlagen, dass die Heizeinheit derInduktionskochfeldvorrichtung, die mit ihren Heizelementen den variablen Kochbereich definiert, zumindest teilweise mit der Sensoreinheit einstückig ausgebildet ist. Insbesondere sind die Heizelemente als Induktionsheizelemente, also als Induktoren bzw. Spulen ausgebildet und sind somit geeignet, auf induktivem Weg eine Anwesenheit eines Gargeschirrs zu detektieren. Insbesondere bilden die Heizelemente der Heizeinheit Sensoren der Sensoreinheit. Insbesondere kann eine bauteilsparende Ausgestaltung erreicht werden. Insbesondere kann auf zusätzliche Sensoren verzichtet werden. Alternativ ist es denkbar, dass die Heizelemente als Strahlungsheizkörper und/oder Widerstandsheizkörper ausgebildet sind. Weiterhin ist es denkbar, dass die Sensoren unabhängig von den Heizelementen ausgebildet sind. Insbesondere sind zwischen, um und/oder über den Heizelementen zusätzlich Sensoren, insbesondere induktive Sensoren, angeordnet.Furthermore, it is proposed that the heating unit of the induction hob unit, which defines the variable cooking area with its heating elements, is at least partially formed integrally with the sensor unit. In particular, the heating elements are designed as induction heating elements, that is to say as inductors or coils, and are therefore suitable for inductively detecting the presence of cooking utensils. In particular, the heating elements of the heating unit form sensors of the sensor unit. In particular, a component-saving design can be achieved. In particular, can be dispensed with additional sensors. Alternatively, it is conceivable that the heating elements are designed as radiant heaters and / or resistance heaters. Furthermore, it is conceivable that the sensors are formed independently of the heating elements. In particular, sensors, in particular inductive sensors, are additionally arranged between, around and / or over the heating elements.

Die Heizelemente 14 sind in einer hexagonalen Matrix angeordnet. Die Heizelemente 14 sind unterhalb der Kochfeldplatte 24 angeordnet. Der variable Kochbereich 26 ist von der Vielzahl an Heizelementen 14 definiert. FIG. 1 1 shows a hob 10 with a cooktop device 11 designed as an induction cooktop device. The cooktop device 11 has a variable cooking region 26. The variable cooking area 26 is arranged on a hob plate 24 of the hob device 11. The hob apparatus 11 further includes a heating unit 12 having a plurality of heating elements 14 formed as induction heating elements. The heating elements 14 are arranged in a hexagonal matrix. The heating elements 14 are arranged below the hob plate 24. The variable cooking area 26 is defined by the plurality of heating elements 14.

Weiterhin weist die Kochfeldvorrichtung 11 eine Sensoreinheit 16 auf, die dazu vorgesehen ist, Geometriekenngrößen, also Positionen, Formen und Größen von in dem Kochbereich 26 platzierten Gargeschirr 28, zu detektieren. Die Sensoreinheit 16 ist teilweise einstückig mit der Heizeinheit 12 ausgebildet. Die Heizelemente 14 sind mit einer Messelektronik 18 verbunden, die dazu vorgesehen ist, über induktivem Weg einen Bedeckungsgrad der einzelnen Heizelemente 14 zu bestimmen. Aus den Bedeckungsgraden ermittelt die Sensoreinheit 16 Formen, Größen und Positionen von aufgestelltem Gargeschirr 28.Furthermore, the hob device 11 has a sensor unit 16, which is provided to geometry characteristics, ie positions, shapes and sizes of placed in the cooking area 26 cooking utensils 28 to detect. The sensor unit 16 is partially formed integrally with the heating unit 12. The heating elements 14 are connected to a measuring electronics 18, which is provided to determine a degree of coverage of the individual heating elements 14 via an inductive path. From the degrees of coverage, the sensor unit 16 determines shapes, sizes and positions of installed cooking utensils 28.

Weiterhin weist die Kochfeldvorrichtung 11 eine Steuereinheit 20 auf, die unter anderem dazu vorgesehen ist, eine Einzelmessung 58 der Sensoreinheit 16 auf Bedieneranfrage 54 zu starten und hierbei detektierte Geometriekenngrößen zu speichern (Figur 2). Die Steuereinheit 20 ist dazu vorgesehen, die detektierten Geometriekenngrößen so lange zu speichern, bis eine Resetsituation auftritt. Die Steuereinheit 20 ist dazu vorgesehen, die detektierten Geometriekenngrößen über eine Wartezeit 66 hinaus zu speichern. Die Steuereinheit 20 ist dazu vorgesehen, nach der Wartezeit 66 in einen Ruhemodus 68 zu wechseln, wobei ein Großteil einer Recheneinheit der Steuereinheit 20 und die Anzeigeeinheit 22 deaktiviert werden. Die Wartezeit 66 beträgt 5 Minuten. Alternativ sind auch andere Wartezeiten und/oder eine Deaktivierung des Ruhemodus 68 denkbar.Furthermore, the hob device 11 has a control unit 20, which is provided inter alia for starting a single measurement 58 of the sensor unit 16 on operator request 54 and for storing detected geometry characteristics ( FIG. 2 ). The control unit 20 is provided to store the detected geometry characteristics until a reset situation occurs. The control unit 20 is intended to store the detected geometry parameters beyond a waiting time 66. The control unit 20 is provided to switch to a rest mode 68 after the waiting time 66, wherein a large part of a computing unit of the control unit 20 and the display unit 22 are deactivated. The waiting time 66 is 5 minutes. Alternatively, other waiting times and / or a deactivation of the sleep mode 68 are conceivable.

Ferner weist die Kochfeldvorrichtung 11 eine Anzeigeeinheit 22 auf, wobei die Steuereinheit 20 dazu vorgesehen ist, die detektierten Geometriekenngrößen über die Anzeigeeinheit 22 zu visualisieren. Die Steuereinheit 20 ist dazu vorgesehen die detektierten Geometriekenngrößen in einem Betriebsmodus, in dem keine Bedieneranfrage 54, 56 erfolgt, über die Anzeigeeinheit 22 zu visualisieren, bis die Wartezeit 66 abgelaufen ist. Die Anzeigeeinheit 22 ist als Bedienerschnittstelleneinheit ausgebildet. Die Anzeigeeinheit 22 ist als berührungsempfindlicher Bildschirm ausgebildet.Furthermore, the hob device 11 has a display unit 22, wherein the control unit 20 is provided to visualize the detected geometry characteristics via the display unit 22. The control unit 20 is provided to visualize the detected geometry parameters in an operating mode in which no operator request 54, 56 takes place via the display unit 22 until the waiting time 66 has expired. The display unit 22 is as an operator interface unit educated. The display unit 22 is designed as a touch-sensitive screen.

Bei einem Einschalten 50 des Kochfelds 10 bzw. der Kochfeldvorrichtung 11 wird die Anzeigeeinheit 22 mit leerem Inhalt initialisiert. Darufhin wird in einer Warteschleife 52 auf eine Bedieneranfrage 54, 56 gewartet. Erfolgt während dieser Warteschleife 52 eine erste Bedieneranfrage 54, indem eine freie Fläche des visualisierten Kochfelds auf der Anzeigeeinheit 22 betätigt wird, wird eine Einzelmessung 58 durchgeführt. Hierbei detektierte Geometriekenngrößen überschreiben, insoweit diese vorhanden sind, Geometriekenngrößen einer zuvor stattgefundenen Einzelmessung 58. Die Steuereinheit 20 legt entsprechend einer Anzahl an detektierten Gargeschirren 28 und in Abhängigkeit von detektierten Geometriekenngrößen Gruppen von Heizelementen 14 fest, die jeweils eine Heizzone 30 definieren (schraffiert angedeutet). Es erfolgt eine Visualisierung 60 der Geometriekenngröße auf der Anzeigeeinheit 22 und eine Rückkehr in die Warteschleife 52. Erfolgt während der Warteschleife 52 eine zweite Bedieneranfrage 56, indem eine Fläche des visualisierten Kochfelds, an der Geometriekenngrößen des detektierten Gargeschirrs 28 angezeigt, auf der Anzeigeeinheit 22 betätigt wird, wird ein Leistungseinstellungsmenü auf der Anzeigeeinheit 22 dargestellt, das eine Heizleistungsauswahl 62 für das ausgewählte Gargeschirr 28 bzw. die entsprechende Heizzone 30 durch den Bediener ermöglicht. Die Steuereinheit 20 führt nach Auswahl der Heizleistung eine Leistungseinstellung 64 bzw. Heizleistungsregelung der Heizzone 30 aus. Anschließend kehrt die Steuereinheit 20 in die Warteschleife 52 zurück, nachdem erneut die Visualisiserung der detektierten Geometriekenngrößen durchgeführt wurde.Upon switching on 50 of the hob 10 and the hob device 11, the display unit 22 is initialized with empty content. As a result, an operator request 54, 56 is awaited in a waiting loop 52. If a first operator request 54 is made during this queue 52 by actuating a blank area of the visualized cooktop on the display unit 22, a single measurement 58 is made. The control unit 20 sets according to a number of detected cooking dishes 28 and depending on detected geometry characteristics groups of heating elements 14, each defining a heating zone 30 (hatched indicated) , There is a visualization 60 of the geometry parameter on the display unit 22 and a return to the queue 52. During the queue 52, a second operator request 56 is made by actuating on the display unit 22 an area of the visualized cooktop displayed on the geometry characteristics of the detected cookware 28 is displayed, a power settings menu is displayed on the display unit 22, which allows a Heizleistungsauswahl 62 for the selected cooking utensils 28 and the corresponding heating zone 30 by the operator. After selecting the heating power, the control unit 20 performs a power setting 64 or heating power control of the heating zone 30. Subsequently, the control unit 20 returns to the holding pattern 52, after again the visualization of the detected geometry characteristics was performed.

Wird die Warteschleife 52, während keiner Heizzone 30 eine Heizleistung über Null zugeordnet ist, länger als die Wartezeit 66 ausgeführt, wechselt die Steuereinheit 20 in den Ruhemodus 68. Im Ruhemodus 68 wird weiterhin auf eine reaktivierende Bedieneranfrage 70 gewartet. Wird eine weitere Wartezeit 72 von 30 Minuten überschritten, wird das Kochfeld 10 und somit die Kochfeldvorrichtung 11 in einem Abschaltvorgang 74 abgeschaltet. Bei dem Abschaltvorgang 74 werden die detektieren und abgespeicherten Geometriekenngrößen gelöscht. Erfolgt innerhalb der weiteren Wartezeit 72 eine Bedieneranfrage 70, werden die Steuereinheit 20 und die Anzeigeeinheit 22 bei einer Reaktivierung 76 wieder eingeschaltet. Nach der Reaktivierung 76 erfolgt erneut die Visualisierung 60 mit den abgespeicherten, detektierten Geometriekenngrößen und eine Rückkehr in die Warteschleife 52.If the queues 52, while no heating zone 30 is assigned a heating power above zero, carried out longer than the waiting time 66, the control unit 20 changes to the idle mode 68. In idle mode 68, a reactivating operator request 70 is still waiting. If a further waiting time 72 of 30 minutes is exceeded, the hob 10 and thus the hob device 11 are turned off in a shutdown 74. In the shutdown process 74, the detected and stored geometry characteristics are deleted. If an operator request 70 is made within the further waiting time 72, the control unit 20 and the display unit 22 are switched on again in the case of a reactivation 76. After the reactivation 76, the visualization 60 with the stored, detected geometry parameters and a return to the waiting loop 52 takes place again.

Weiterhin ist es vorgesehen, dass der Bediener über weitere Bedieneranfragen (hier nicht dargestellt) innerhalb der Warteschleife 52 in ein Konfigurationsmenü der Kochfeldvorrichtung 11 gelangt, um Gerätegrundeinstellungen und Ähnliches anzupassen. Weiterhin ist es denkbar, dass das Konfigurationsmenü nur aufrufbar ist, wenn keiner Heizzone 30 eine Heizleistung zugeordnet ist.Furthermore, it is provided that the operator, via further user requests (not shown here) within the waiting loop 52, enters a configuration menu of the cooktop device 11 in order to adapt basic device settings and the like. Furthermore, it is conceivable that the configuration menu can only be called if no heating zone 30 is assigned a heating power.
