Die Auswerteeinheit 20 ist mit einer nicht dargestellten Messeinheit, welche einen durch die Heizelemente 14 fließenden Heizstrom und eine Heizleistung der Heizelemente 14 misst, und mit einem nicht dargestellten Topferkennungssystem, das die Aufstellposition 16 des Gargefäßes ermittelt, verbunden. Die Auswerteeinheit 20 umfasst eine Prozessoreinheit und eine Speichereinheit mit einem darin gespeicherten Betriebsprogramm, das von der Prozessoreinheit ausgeführt wird. Unterhalb der Aufstellfläche 12 sind Beleuchtungselemente 26 angeordnet, die jeweils entlang einem Umfang der als Induktionsspulen ausgebildeten Heizelemente 14 verlaufen und die von der Prozessoreinheit angesteuert werden können. Durch eine Ansteuerung der Beleuchtungselemente 26 durch die Prozessoreinheit senden die Beleuchtungselemente 26 rotes Licht aus. Die Aufstellfläche 12 ist aus einer dunklen Glaskeramik hergestellt, welche für rotes Licht durchlässig ist, so dass ein Benutzer ein Aufleuchten der Beleuchtungselemente 26 durch die Aufstellfläche 12 hindurch erkennen kann. Fig. 1 shows a designed as an induction hob apparatus for an induction matrix cooktop Gargerätvorrichtung 10 with a footprint 12 for setting up cooking vessels, especially induction pots and induction pans, and with a plurality of heating elements 14, which are arranged below the footprint 12 and provided for heating cooking vessels. The heating elements 14 are formed by induction coils. On the footprint 12, a cooking vessel is placed at an installation position 16, the four heating elements 14 each partially covered. The cooking device device 10 comprises an evaluation unit 20, which is provided to determine at least one parameter with regard to a heating efficiency of at least one cooking vessel and output via a display unit designed as a display unit 22 at least one information regarding the characteristic for the cooking vessel. The output unit 22 is connected to the evaluation unit 20 via a data connection 24. The evaluation unit 20 is connected to a measuring unit, not shown, which measures a heating current flowing through the heating elements 14 and a heating power of the heating elements 14, and with a pot detection system, not shown, which determines the installation position 16 of the cooking vessel. The evaluation unit 20 comprises a processor unit and a memory unit having an operating program stored therein executed by the processor unit. Below the footprint 12 lighting elements 26 are arranged, each extending along a circumference of the induction coil formed as heating elements 14 and which can be controlled by the processor unit. By controlling the illumination elements 26 by the processor unit, the illumination elements 26 emit red light. The footprint 12 is made of a dark glass ceramic, which is transparent to red light, so that a user can detect a lighting up of the lighting elements 26 through the footprint 12 therethrough.

Die Auswerteeinheit 20 bestimmt in einem analytischen Rechenprozess eine effiziente Heizposition 18. Die Auswerteeinheit 20 gibt über die Ausgabeeinheit 22 eine Positionsinformation über die effiziente Heizposition 18 aus (Fig. 2). Eine Ausgabe der Positionsinformation durch die Ausgabeeinheit 22 erfolgt durch Ausgabe eines Aufstellpositionssymbols 28 und eines Positionssymbols für die effiziente Heizposition 30 im Display. Das Display der Ausgabeeinheit 22 weist zu der Ausgabe der Positionsinformation eine massstabsgetreue Repräsentation der Aufstellfläche 12 auf. Die Ausgabeeinheit 22 weist ferner ein Richtungssymbol 32 in einer Pfeilform auf, welches auf dem Display an einer beliebigen Position eingeblendet werden kann und das eine Verschieberichtung hin zu der effizienten Heizposition 18, ausgehend von einer aktuellen Aufstellposition 16, anzeigt. Die Ausgabeeinheit 22 weist ein Effizienzsignalfeld 34 auf, über das die Auswerteeinheit 20 einen Übereinstimmungswert einer positionalen Heizeffizienz mit einem Effizienzschwellwert ausgibt. Der Effizienzschwellwert ist von dem Wert der positionalen Heizeffizienz der effizienten Heizposition 18 gebildet. Das Effizienzsignalfeld 34 ist rot hinterlegt, wenn eine Heizeffizienz der Aufstellposition 16 niedriger ist als der Effizienzschwellwert, und grün hinterlegt, wenn die Heizeffizienz der Aufstellposition 16 gleich groß ist wie der Effizienzschwellwert. Ferner gibt die Auswerteeinheit 20 über ein Heizeffizienzausgabefeld 36 der Ausgabeeinheit 22 eine Heizeffizienz der Aufstellposition 16 des Gargefäßes aus. Die Heizeffizienz der Aufstellposition 16 wird in dem Heizeffizienzausgabefeld 36 als eine Prozentzahl bezogen auf eine Heizeffizienz der effizienten Heizposition 18 dargestellt.The evaluation unit 20 determines an efficient heating position 18 in an analytical computing process. The evaluation unit 20 outputs position information about the efficient heating position 18 via the output unit 22 (FIG. Fig. 2 ). Output of the position information by the output unit 22 is performed by outputting a set-up position symbol 28 and a position symbol for the efficient heating position 30 in the display. The display of the output unit 22 has to the output of the position information on a scale representation of the footprint 12. The output unit 22 further includes a directional icon 32 in an arrow shape that can be displayed on the display at an arbitrary position and that indicates a direction of displacement toward the efficient heating position 18 from a current set-up position 16. The output unit 22 has an efficiency signal field 34, via which the evaluation unit 20 outputs a match value of a positional heating efficiency with an efficiency threshold value. The efficiency threshold is formed by the value of the positional heating efficiency of the efficient heating position 18. The efficiency signal field 34 is highlighted in red when a heating efficiency of the set-up position 16 is lower than the efficiency threshold, and highlighted in green when the heating efficiency of the set-up position 16 is equal to the efficiency threshold. Furthermore, the evaluation unit 20 outputs a heating efficiency of the setting position 16 of the cooking vessel via a heating efficiency output field 36 of the output unit 22. The heating efficiency of the erecting position 16 is shown in the heating efficiency output field 36 as a percentage with respect to a heating efficiency of the efficient heating position 18.

Zusätzlich kann die Auswerteeinheit 20 dazu vorgesehen sein, die effiziente Heizposition 18 über die Beleuchtungselemente 26 anzuzeigen (Fig. 3). Hierzu steuert die Prozessoreinheit der Auswerteeinheit 20 Beleuchtungselemente 26 an, die an den Heizelementen 14 angeordnet sind, welche von der effizienten Heizposition 18 zumindest teilweise überdeckt sind, wodurch dem Benutzer die effiziente Heizposition 18 angezeigt wird.In addition, the evaluation unit 20 may be provided to display the efficient heating position 18 via the lighting elements 26 ( Fig. 3 ). For this purpose, the processor unit of the evaluation unit 20 controls lighting elements 26 which are connected to the Heating elements 14 are arranged, which are at least partially covered by the efficient heating position 18, whereby the user the efficient heating position 18 is displayed.
