Anderenfalls wird zumindest ein weiterer Rechenschritt analog zu dem ersten Rechenschritt durchgeführt, in dem die Heizposition, die die Heizung des Gargeschirrs mit besserer Übereinstimmung mit dem Optimierungsparameter erlaubt, als gegenwärtige Heizposition betrachtet wird. Unter einem "analytischen Rechenprozess" soll insbesondere ein Rechenprozess verstanden werden, bei dem eine Berechnung der am besten mit dem Optimierungsparameter übereinstimmenden Heizposition durch eine Berechnung von möglichen Aufstellpositionen des Gargeschirrs und Vergleich der jeweiligen Übereinstimmung mit dem Optimierungsparameter erfolgt.

Es wird vorgeschlagen, dass die Steuereinheit dazu vorgesehen ist, eine Auswahlmöglichkeit des Optimierungsparameters bereitzustellen. Insbesondere ist die Steuereinheit dazu vorgesehen, eine Auswahlmöglichkeit zwischen dem wenigstens einen Optimierungsparameter und einem Normalbetrieb bereitzustellen. Beispielsweise ist die Steuereinheit dazu vorgesehen, die Auswahlmöglichkeit einer weiteren Einheit bereitzustellen, die aus der bereitgestellten Auswahlmöglichkeit eine Möglichkeit auswählt. Insbesondere ist die Steuereinheit dazu vorgesehen, einem Bediener eine Auswahlmöglichkeit des Optimierungsparameters bereitzustellen. Unter einem "Normalbetrieb" soll insbesondere ein Betrieb verstanden werden, in welchem die Kochfeldvorrichtung in einem regulären Betrieb, insbesondere unter Vermeidung eines Optimierungsparameters, betrieben werden kann. Unter einer "Auswahlmöglichkeit" soll insbesondere eine Möglichkeit verstanden werden, aus einer vorgegebenen Menge aus zumindest zwei sich unterscheidenden Merkmalen zumindest ein Merkmal auszuwählen. Vorzugsweise sind die zumindest zwei sich unterscheidenden Merkmale durch den wenigstens einen Optimierungsparameter und den Normalbetrieb ausgebildet. Beispielsweise kann eine Auswahlmöglichkeit derart ausgebildet sein, dass der Bediener durch ein Anklicken in einem Benutzerinterface eines der zumindest zwei sich unterscheidenden Merkmale auswählt. Alternativ kann die Auswahlmöglichkeit derart erfolgen, dass der Bediener durch ein Verschieben eines auf einer Kochfläche aufgestellten Gargeschirrs eines der zumindest zwei sich unterscheidenden Merkmale auswählt. Durch eine erfindungsgemäße Ausgestaltung kann vorteilhaft eine bedienerfreundliche Kochvorrichtung erreicht werden, welche flexibel an Bedürfnisse des Bedieners angepasst werden kann.It is proposed that the control unit be provided to provide a choice of the optimization parameter. In particular, the control unit is provided to provide a choice between the at least one optimization parameter and a normal operation. For example, the control unit is provided to provide the possibility of selecting a further unit that selects a possibility from the available selection option. In particular, the control unit is provided to provide an operator with a choice of the optimization parameter. A "normal operation" is to be understood in particular to mean an operation in which the cooktop apparatus can be operated in a regular operation, in particular while avoiding an optimization parameter. A "possibility of choice" is to be understood as meaning, in particular, a possibility from a predetermined quantity At least two distinctive features to select at least one feature. Preferably, the at least two distinguishing features are formed by the at least one optimization parameter and the normal operation. For example, a selection option can be configured such that the operator selects one of the at least two distinguishing features by clicking in a user interface. Alternatively, the choice can be made such that the operator selects one of the at least two differing features by moving a cooking utensil erected on a cooking surface. By means of an embodiment according to the invention, a user-friendly cooking device can advantageously be achieved, which can be flexibly adapted to the needs of the operator.
Ferner wird vorgeschlagen, dass die Steuereinheit dazu vorgesehen ist, eine Auswahlmöglichkeit aus wenigstens zwei Optimierungsparametern bereitzustellen. Insbesondere ist die Steuereinheit dazu vorgesehen, eine Auswahlmöglichkeit zwischen wenigstens zwei sich in wenigstens einem Merkmal unterscheidenden Optimierungsparametern und einem Normalbetrieb bereitzustellen. Insbesondere ist die Steuereinheit dazu vorgesehen, dem Bediener eine Auswahlmöglichkeit aus wenigstens zwei Optimierungsparametern bereitzustellen. Durch eine erfindungsgemäße Ausgestaltung kann vorteilhaft eine bedienerfreundliche Kochvorrichtung erreicht werden, welche flexibel an Bedürfnisse des Bedieners angepasst werden kann.It is further proposed that the control unit is provided to provide a choice of at least two optimization parameters. In particular, the control unit is provided to provide a choice between at least two optimization parameters differing in at least one feature and a normal operation. In particular, the control unit is provided to provide the operator with a choice of at least two optimization parameters. By means of an embodiment according to the invention, a user-friendly cooking device can advantageously be achieved, which can be flexibly adapted to the needs of the operator.
Zudem wird vorgeschlagen, dass die Steuereinheit dazu vorgesehen ist, die Auswahlmöglichkeit in Abhängigkeit von wenigstens einem Parameter bereitzustellen. Beispielsweise kann der wenigstens eine Parameter in der Recheneinheit und/oder Speichereinheit der Steuereinheit vordefiniert gespeichert sein. Insbesondere ist der wenigstens eine Parameter durch den Bediener einstellbar. Unter der Wendung "die Auswahlmöglichkeit in Abhängigkeit von wenigstens einem Parameter bereitstellen" soll insbesondere verstanden werden, dass der wenigstens eine Parameter dazu vorgesehen ist, zumindest eine Eigenschaft der Auswahlmöglichkeit festzulegen. Beispielsweise kann die zumindest eine Eigenschaft der Auswahlmöglichkeit eine Eigenschaft des zumindest einen Optimierungsparameters sein. Die Eigenschaft des zumindest einen Optimierungsparameters kann beispielsweise derart ausgestaltet sein, dass in Abhängigkeit von dem wenigstens einen Parameter zumindest zwei sich in wenigstens einem Merkmal unterscheidende Sätze an Optimierungsparametern als Auswahlmöglichkeit angeboten werden. Die zumindest zwei sich in wenigstens einem Merkmal unterscheidende Sätze können beispielsweise derart ausgebildet sein, dass die jeweiligen Sätze eine unterschiedliche Anzahl an Optimierungsparametern aufweisen. Alternativ oder zusätzlich ist denkbar, dass die jeweiligen Sätze zumindest zwei sich in wenigstens einem Merkmal unterscheidende Optimierungsparameter aufweisen. Beispielsweise ist ebenfalls denkbar, dass die durch den wenigstens einen Parameter festgelegte Eigenschaft der Auswahlmöglichkeit ein Zeitpunkt ist, zu welchem die Steuereinheit die Auswahlmöglichkeit bereitstellt. Insbesondere ist die durch den wenigstens einen Parameter festgelegte Eigenschaft der Auswahlmöglichkeit eine Bereitstellungsfrequenz, mit welcher die Steuereinheit die Auswahlmöglichkeit bereitstellt. Insbesondere hängt der wenigstens eine Parameter von der wenigstens einen Gargeschirrkenngröße ab. Beispielsweise kann die Bereitstellungsfrequenz für große Gargeschirre erniedrigt sein, so dass die Steuereinheit im Vergleich zu kleinen Gargeschirren die Auswahlmöglichkeit seltener bereitstellt. Alternativ oder zusätzlich kann die Bereitstellungsfrequenz für kleine Gargeschirre erhöht sein, so dass die Steuereinheit im Vergleich zu großen Gargeschirren die Auswahlmöglichkeit häufiger bereitstellt. Durch eine erfindungsgemäße Ausgestaltung kann vorteilhaft eine flexibel ausgestaltete Auswahlmöglichkeit bereitgestellt werden, wodurch ein Komfort für einen Bediener erhöht werden kann.In addition, it is proposed that the control unit is provided to provide the option in dependence on at least one parameter. For example, the at least one parameter can be stored in the arithmetic unit and / or memory unit of the control unit in a predefined manner. In particular, the at least one parameter is adjustable by the operator. By the phrase "provide the option as a function of at least one parameter" is to be understood in particular that the at least one parameter is intended to specify at least one property of the selection option. For example, the at least one property of the selection option may be a property of the at least one optimization parameter. The property of the at least one optimization parameter can be configured, for example, such that, depending on the at least one parameter, at least two in at least a feature distinctive sets of optimization parameters are offered as a choice. The at least two sets which differ in at least one feature may for example be designed such that the respective sets have a different number of optimization parameters. Alternatively or additionally, it is conceivable that the respective sets have at least two optimization parameters that differ in at least one feature. For example, it is also conceivable that the property of the selection option determined by the at least one parameter is a time at which the control unit provides the selection option. In particular, the property of the choice determined by the at least one parameter is a delivery frequency with which the control unit provides the selection option. In particular, the at least one parameter depends on the at least one cooking dish characteristic. For example, the supply frequency for large cooking utensils can be lowered, so that the control unit provides the choice less frequently compared to small cooking utensils. Alternatively or additionally, the supply frequency for small cooking utensils may be increased, so that the control unit makes the selection more frequent compared to large cooking utensils. By means of an embodiment according to the invention, advantageously a flexibly configured selection option can be provided, whereby a comfort for an operator can be increased.
Weiterhin wird vorgeschlagen, dass die Steuereinheit dazu vorgesehen ist, die Auswahlmöglichkeit über einen einstellbaren Bereitstellungszeitraum bereitzustellen.

Insbesondere hat ein Bediener lediglich in dem Bereitstellungszeitraum die Gelegenheit, ein Merkmal der Auswahlmöglichkeit auszuwählen. Vorzugsweise kann der Bediener den Bereitstellungszeitraum nach seinen Bedürfnissen wählen. Beispielsweise kann der Bediener jeglichen seinen Bedürfnissen entsprechenden Bereitstellungszeitraum einstellen, wie beispielsweise 30 sec, 60 sec, 2 min oder jeder andere, einem Fachmann als sinnvoll erscheinende Bereitstellungszeitraum. Insbesondere kann der Bediener den Bereitstellungszeitraum auf 0 sec einstellen, so dass ein Betreiben der Kochfeldvorrichtung in dem Normalbetrieb unter Vermeidung der Auswahlmöglichkeit ermöglicht wird. Durch eine erfindungsgemäße Ausgestaltung kann vorteilhaft eine flexibel ausgestaltete Auswahlmöglichkeit bereitgestellt werden, wodurch ein Komfort für einen Bediener erhöht werden kann.Furthermore, it is proposed that the control unit is provided to provide the choice over an adjustable provisioning period. In particular, the provisioning period is adjustable by the operator. A "provision period" is to be understood, in particular, as a period of time within which the control unit provides the operator with the option of selection. In particular, an operator only has the opportunity during the provisioning period to select a feature of the selection option. Preferably, the operator may choose the provisioning period according to his needs. For example, the operator may set any provisioning period appropriate to his needs, such as 30 seconds, 60 seconds, 2 minutes or any other provisioning period deemed appropriate by those skilled in the art. In particular, the operator can set the provision period to 0 sec, so that operating the hob device in the normal operation while avoiding the possibility of selection is possible. By means of an embodiment according to the invention, advantageously a flexibly configured selection option can be provided, whereby a comfort for an operator can be increased.

Beispielsweise kann der Bediener die von der Steuereinheit in dem zumindest einen Vorschlag bereitgestellte Position des Gargeschirrs auswählen. Alternativ kann der Bediener eine andere, sich von der in dem zumindest einen Vorschlag bereitgestellten Position unterscheidende Position für das Gargeschirr auswählen. Insbesondere ist die Steuereinheit dazu vorgesehen, eine von dem Bediener ausgewählte Position des Gargeschirrs zu akzeptieren. Durch eine erfindungsgemäße Ausgestaltung kann vorteilhaft eine Bedienerfreundlichkeit und damit ein Komfort für den Bediener erhöht werden.It is further proposed that the control unit is provided to provide at least a proposal for a position of the cooking utensils. In particular, the control unit is provided to provide the operator at least a suggestion for a position of the cooking utensils.

In particular, the control unit is provided to provide the operator with the at least one suggestion as a function of the at least one optimization parameter. Such a configuration can make it easier for the operator to select the position of the cooking utensil. Preferably, the operator may select any position of the cooking utensil. For example, the operator may select the position of the cooking utensil provided by the control unit in the at least one suggestion. Alternatively, the operator may select another position for the cooking utensil different from that provided in the at least one suggestion. In particular, the control unit is provided to accept a position of the cooking utensil selected by the operator.

Insbesondere kann die wenigstens eine Kenngröße als eine optische Kenngröße und/oder als eine akustische Kenngröße ausgebildet sein. Beispielsweise kann eine optische Kenngröße als ein Balken oder eine Säule ausgebildet sein, wobei jeweils eine Angabe von prozentualen Zahlenwerten beigefügt oder vermieden werden kann. Weiterhin ist denkbar, dass die optische Kenngröße als eine reine Angabe eines prozentualen Zahlenwerts ausgebildet sein kann. Eine akustische Kenngröße kann beispielsweise ein in einer Lautstärke variierendes Signal sein, welches beispielsweise an Lautstärke zunimmt, wenn eine aktuelle Position des Gargeschirrs mit dem wenigstens einen Optimierungsparameter besser übereinstimmt als eine der aktuellen Position vorangegangene Position. Durch eine erfindungsgemäße Ausgestaltung kann vorteilhaft ein dem wenigstens einen Optimierungsparameter entsprechender Standort des Gargeschirrs einfach gefunden werden. Dadurch kann eine Bedienerfreundlichkeit erhöht werden.Furthermore, it is proposed that the control unit be provided to output at least one parameter which indicates to what extent a location of the cooking utensil corresponds to the at least one optimization parameter. In particular, the control unit is provided to output to the operator at least one parameter which indicates to what extent a location of the cooking utensil corresponds to the at least one optimization parameter. In particular, the at least one parameter can be designed as an optical parameter and / or as an acoustic parameter. For example, an optical characteristic may be formed as a bar or a column, wherein an indication of percentage numerical values can be added or avoided in each case. Furthermore, it is conceivable that the optical characteristic can be designed as a mere indication of a percentage numerical value. An acoustic parameter may, for example, be a signal varying in a volume which, for example, increases in volume if a current position of the cooking utensil matches the at least one optimization parameter better than a position preceding the current position. By means of an embodiment according to the invention, advantageously, a location of the cooking utensil corresponding to the at least one optimization parameter can be found easily.
