Der Erfindung stellt sich das Problem, die Nutzung eines Systems, umfassend ein induktives Kochfeld und ein Aufstellgerät, zu verbessern.The invention addresses the problem of improving the use of a system comprising an inductive hob and a set-up device.

Erfindungsgemäß wird dieses Problem durch ein Aufstellgerät mit den Merkmalen des Patentanspruchs 1 gelöst. Ferner wird dieses Problem durch ein System mit den Merkmalen des Patentanspruchs 7 sowie ein Verfahren mit den Merkmalen des Patentanspruchs 11 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.According to the invention, this problem is solved by a set-up device with the features of patent claim 1. Furthermore, this problem is solved by a system with the features of patent claim 7 and a method with the features of patent claim 11. Advantageous refinements and further developments of the invention result from the dependent claims.

Der mit der Erfindung erreichbare Vorteil besteht insbesondere darin, dass die Nutzung eines Systems, umfassend ein induktives Kochfeld und ein Aufstellgerät, verbessert ist. Beispielsweise ist der Bedienkomfort für einen Benutzer derartiger Systeme gesteigert. Aufgrund der automatischen Erkennung eines Aufstellereignisses oder eines Aufstellereignisses und der Beschaffenheit einer Unterlage, auf der das Aufstellgerät aufgestellt worden ist, ist es möglich, die Handhabung des erfindungsgemäßen Aufstellgeräts wie auch des erfindungsgemäßen Systems zu vereinfachen. Beispielsweise ist es damit möglich, einen Eingriff eines Benutzers automatisch zu erkennen und für die weitere Steuerung oder Regelung des Systems zu verwenden. Ferner können nachfolgende Schritte in der Zubereitung eines in dem Aufstellgerät befindlichen Mediums mittels des induktiven Kochfelds antizipiert werden, um so die weitere Zubereitung zu vereinfachen. Auch ist es mittels der Erfindung möglich, beispielsweise das induktive Kochfeld vor einer unsachgemäßen Handhabung zu schützen, so dass eine etwaige Beschädigung des induktiven Kochfelds sowie möglicherweise die Sicherheit gefährdende Situationen wirksam verhindert sind. Darüber hinaus ist es mittels der Erfindung möglich, den Energieverbrauch des Aufstellgeräts und des induktiven Kochfelds zu reduzieren, beispielsweise dadurch, dass lediglich dann eine Signalübertragung zwischen dem Aufstellgerät und der Kochfeldsteuerung des induktiven Kochfelds erfolgt, wenn ein Aufstellereignis oder ein Aufstellereignis und die Beschaffenheit einer Unterlage, auf der das Aufstellgerät aufgestellt worden ist, mittels des Sensors erkannt worden ist/sind. Der Begriff "Aufstellgerät" ist weit auszulegen und umfasst insbesondere alle denkbaren Arten von Kochgeschirr, beispielsweise Kochtöpfe oder Bratpfannen.The advantage that can be achieved with the invention is, in particular, that the use of a system comprising an inductive hob and a set-up device is improved. For example, the ease of use for a user of such systems is increased. Due to the automatic recognition of an installation event or an installation event and the nature of a surface on which the installation device has been set up, it is possible to simplify the handling of the installation device according to the invention as well as the system according to the invention. For example, it is possible to automatically recognize a user's intervention and use it for further control or regulation of the system. The following steps can also be taken can be anticipated in the preparation of a medium located in the set-up device using the inductive hob in order to simplify further preparation. The invention also makes it possible, for example, to protect the inductive hob from improper handling, so that any damage to the inductive hob and potentially safety-endangering situations are effectively prevented. In addition, the invention makes it possible to reduce the energy consumption of the set-up device and the inductive hob, for example by signal transmission between the set-up device and the hob control of the inductive hob only taking place when an installation event or an installation event and the condition of a base , on which the set-up device was set up, was/are detected by the sensor. The term “set-up device” is to be interpreted broadly and includes in particular all conceivable types of cookware, for example cooking pots or frying pans.

Das Aufstellgerät ist nach Art, Funktionsweise, Form, Material und Dimensionierung in weiten geeigneten Grenzen frei wählbar. Dies gilt auch für den Sensor des Aufstellgeräts. Eine vorteilhafte Weiterbildung des Aufstellgeräts sieht vor, dass der Sensor als ein Schwingungssensor und/oder als ein Beschleunigungssensor ausgebildet ist. Auf diese Weise ist der Sensor auf einfache und gleichzeitig funktionssichere Art realisiert. Ferner ist es damit möglich, nachfolgende Schritte in der Zubereitung eines in dem Aufstellgerät befindlichen Mediums mittels des induktiven Kochfelds verbessert zu antizipieren, um so die weitere Zubereitung zusätzlich zu vereinfachen. Darüber hinaus ist mittels der Erfindung gemäß dieser Weiterbildung der Schutz des induktiven Kochfelds vor einer unsachgemäßen Handhabung weiter verbessert, so dass eine etwaige Beschädigung des induktiven Kochfelds sowie möglicherweise die Sicherheit gefährdende Situationen noch wirksamer verhindert sind.The set-up device can be freely selected according to type, functionality, shape, material and dimensions within wide appropriate limits. This also applies to the sensor of the set-up device. An advantageous development of the installation device provides that the sensor is designed as a vibration sensor and/or as an acceleration sensor. In this way, the sensor is implemented in a simple and at the same time functionally reliable manner. Furthermore, it is possible to better anticipate subsequent steps in the preparation of a medium located in the set-up device using the inductive hob, in order to further simplify further preparation. In addition, by means of the invention according to this development, the protection of the inductive hob against improper handling is further improved, so that any damage to the inductive hob and potentially safety-endangering situations are prevented even more effectively.

Zweckmäßigerweise ist es vorgesehen, dass der mindestens eine Sensor an einem Griff des Aufstellgeräts und/oder an einem Gefäß des Aufstellgeräts zur Aufnahme eines für die Zubereitung mittels des Aufstellgeräts vorgesehenen Mediums angeordnet ist. Eine Anordnung des Sensors an dem Griff des Aufstellgeräts hat beispielsweise den Vorteil, dass der Sensor in einem thermisch isolierten Bereich angeordnet ist. Eine Anordnung des Sensors an dem Gefäß des Aufstellgeräts hat wiederum den Vorteil, dass der Sensor näher zu dem Ort der Krafteinleitung bei dem Aufstellen des Aufstellgeräts auf die Unterlage, beispielsweise einer Kochstelle des induktiven Kochfelds, angeordnet ist.It is expediently provided that the at least one sensor is arranged on a handle of the set-up device and/or on a vessel of the set-up device for receiving a medium intended for preparation by means of the set-up device. Arranging the sensor on the handle of the set-up device has the advantage, for example, that the sensor is arranged in a thermally insulated area. Arranging the sensor on the vessel of the set-up device in turn has the advantage that the sensor is arranged closer to the location of the introduction of force when setting up the set-up device on the base, for example a hotplate of the inductive hob.

Eine weitere vorteilhafte Weiterbildung des Aufstellgeräts sieht vor, dass das Aufstellgerät zusätzlich ein Bedienelement zur manuellen Bedienung durch den Benutzer aufweist, wobei sich der Funktionsumfang des Sensors mit dem Funktionsumfang des Bedienelements zumindest teilweise überschneidet. Hierdurch ist eine Redundanz zu dem Sensor geschaffen. Ferner ist es beispielsweise denkbar, dass das Bedienelement zum Ausschalten des Aufstellgeräts dient.A further advantageous development of the set-up device provides that the set-up device additionally has a control element for manual operation by the user, whereby the range of functions of the sensor corresponds to the range of functions of the control element at least partially overlapping. This creates redundancy for the sensor. Furthermore, it is conceivable, for example, that the control element serves to switch off the set-up device.

Eine andere vorteilhafte Weiterbildung des Aufstellgeräts sieht vor, dass das Aufstellgerät derart ausgebildet und eingerichtet ist, dass die Sendeeinheit und/oder die Messeinheit und/oder der Sensor mittels der Induktionsspule mit einer Betriebsenergie versorgbar ist/sind. Auf diese Weise ist es möglich, dass lediglich ein kleiner und damit platzsparender Energiespeicher zur Speicherung der Betriebsenergie für das Aufstellgerät ausreichend ist.Another advantageous development of the set-up device provides that the set-up device is designed and set up in such a way that the transmitting unit and/or the measuring unit and/or the sensor can be supplied with operating energy by means of the induction coil. In this way, it is possible that only a small and therefore space-saving energy storage device is sufficient to store the operating energy for the set-up device.

Entsprechend sieht eine vorteilhafte Weiterbildung des Systems vor, dass die Sendeeinheit und/oder die Messeinheit und/oder der Sensor bei einer mittels der Heizspule in die Induktionsspule des auf der dieser Heizspule zugeordneten Kochstelle aufgestellten Aufstellgeräts induzierten Spannung mit einer Betriebsenergie versorgbar ist/sind.Accordingly, an advantageous development of the system provides that the transmitting unit and/or the measuring unit and/or the sensor can be supplied with operating energy when the voltage is induced by means of the heating coil into the induction coil of the device set up on the cooking area assigned to this heating coil.

Ferner sieht eine vorteilhafte Weiterbildung des Aufstellgeräts vor, dass das Aufstellgerät eine Aufstellgerät-Ausgabeeinheit zur Ausgabe von Informationen an den Benutzer des Aufstellgeräts aufweist, wobei in Abhängigkeit von einem mittels des Sensors erkannten Aufstellereignisses oder einer mittels des Sensors erkannten Unterlage, auf der das Aufstellgerät aufgestellt worden ist, mittels der Aufstellgerät-Ausgabeeinheit eine Information an den Benutzer ausgebbar ist. Hierdurch ist eine Rückmeldung, beispielsweise über das Vorliegen eines Aufstellereignisses oder die Beschaffenheit der Unterlage, an den Benutzer des Aufstellgeräts ermöglicht. Beispielsweise ist es denkbar, dass bei einem noch Restwärme aufweisenden Aufstellgerät als Information ein Warnsignal ausgegeben wird, wenn mittels des Sensors erkannt worden ist, dass es sich bei der Unterlage, auf der das Aufstellgerät aufgestellt worden ist, nicht um eine Kochstelle des induktiven Kochfelds, sondern um eine Unterlage aus Holz oder Stoff handelt.Furthermore, an advantageous development of the setting-up device provides that the setting-up device has a setting-up device output unit for outputting information to the user of the setting-up device, depending on a setting-up event recognized by the sensor or a surface recognized by the sensor on which the setting-up device is set up has been made, information can be output to the user by means of the set-up device output unit. This enables feedback to the user of the installation device, for example about the existence of an installation event or the condition of the base. For example, it is conceivable that in the case of a set-up device that still has residual heat, a warning signal is issued as information if the sensor has detected that the surface on which the set-up device has been set up is not a hotplate of the inductive hob, but rather a base made of wood or fabric.

Entsprechend sieht eine weitere vorteilhafte Weiterbildung des Systems vor, dass das induktive Kochfeld eine Kochfeld-Ausgabeeinheit zur Ausgabe von Informationen an den Benutzer des Aufstellgeräts aufweist, wobei in Abhängigkeit von einem mittels des Sensors erkannten Aufstellereignisses oder einer mittels des Sensors erkannten Unterlage, auf der das Aufstellgerät aufgestellt worden ist, mittels der Kochfeld-Ausgabeeinheit eine Information an den Benutzer ausgebbar ist.Accordingly, a further advantageous development of the system provides that the inductive hob has a hob output unit for outputting information to the user of the installation device, depending on an installation event recognized by the sensor or a surface recognized by the sensor on which the Set-up device has been set up, information can be output to the user by means of the hob output unit.

Erfindungsgemäß ist ein System vorgesehen, bei dem die Kochfeldsteuerung derart ausgebildet und eingerichtet, dass das induktive Kochfeld in einem Bereitschaftsmodus betreibbar ist, wobei das induktive Kochfeld mittels eines von einer Empfangseinheit der Kochfeldsteuerung empfangenen Wecksignals von dem Standby-Modus in den Bereitschaftsmodus überführbar ist, wobei die jeweilige Heizspule in dem Bereitschaftsmodus mittels der Kochfeldsteuerung derart ansteuerbar ist, dass zum einen eine für einen Zubereitungsvorgang wirksame Beheizung des Aufstellgeräts verhindert ist und zum anderen eine Signalübertragung zwischen der Sendeeinheit und der Empfangseinheit mittels der Heizspule ermöglicht ist.According to the invention, a system is provided in which the hob control is designed and set up in such a way that the inductive hob can be operated in a standby mode, the inductive hob being able to be transferred from standby mode to standby mode by means of a wake-up signal received from a receiving unit of the hob control, whereby the respective heating coil in the standby mode can be controlled by means of the hob control in such a way that, on the one hand, effective heating of the set-up device for a preparation process is prevented and, on the other hand, signal transmission between the transmitting unit and the receiving unit is made possible by means of the heating coil.

Entsprechend sieht auch eine vorteilhafte Weiterbildung des Verfahrens vor, dass in Abhängigkeit von einem mittels des Sensors erkannten Aufstellereignisses oder einer mittels des Sensors erkannten Unterlage, auf der das Aufstellgerät aufgestellt worden ist, mittels der Aufstellgerät-Ausgabeeinheit und/oder mittels der Kochfeld-Ausgabeeinheit eine Information an den Benutzer ausgegeben wird.Accordingly, an advantageous development of the method also provides that, depending on a setting-up event detected by the sensor or a surface on which the set-up device has been set up, detected by the sensor, by means of the set-up device output unit and/or by means of the hob output unit Information is output to the user.

Grundsätzlich ist es denkbar, dass die Ansteuerung der Heizspule in Abhängigkeit von einem mittels des Sensors erkannten Aufstellereignisses oder einer mittels des Sensors erkannten Unterlage, auf der das Aufstellgerät aufgestellt worden ist, dahingehend erfolgt, dass die Heizspule beispielsweise direkt mit einer für einen Zubereitungsvorgang ausreichenden elektrischen Leistung bestromt wird. Ferner ist es denkbar, dass bei einer Erkennung der Aufstellung des Aufstellgeräts auf eine Kochstelle des induktiven Kochfelds und eines übermäßigen Schwenkens des Aufstellgeräts mittels des Sensors die Zufuhr von elektrischer Leistung automatisch reduziert wird, um beispielsweise Bauteile eines Schwingkreises des induktiven Kochfelds vor einer Beschädigung zu schützen.In principle, it is conceivable that the control of the heating coil takes place depending on an installation event detected by the sensor or a surface on which the installation device has been set up, detected by the sensor, in such a way that the heating coil is, for example, directly connected to an electrical device that is sufficient for a preparation process Power is energized. Furthermore, it is conceivable that when the installation of the set-up device is detected on a hotplate of the inductive hob and excessive pivoting of the set-up device by means of the sensor, the supply of electrical power is automatically reduced in order, for example, to protect components of a resonant circuit of the inductive hob from damage .

Erfindungsgemäß ist ein Verfahren vorgesehen, bei dem in Abhängigkeit von einem mittels des Sensors erkannten Aufstellereignisses das Kochfeld von einem Ausschaltmodus direkt in den Betriebsmodus überführt wird, oder das Kochfeld von dem Standby-Modus automatisch in den Bereitschaftsmodus überführt wird, oder das Kochfeld von dem Standby-Modus in den Betriebsmodus überführt wird.According to the invention, a method is provided in which, depending on an installation event detected by the sensor, the hob is transferred from a switch-off mode directly into the operating mode, or the hob is automatically transferred from the standby mode to the standby mode, or the hob from the standby mode is transferred to operating mode.

Eine vorteilhafte Weiterbildung des Verfahrens sieht vor, dass in Abhängigkeit von einem mittels des Sensors erkannten Aufstellereignisses oder einer mittels des Sensors erkannten Unterlage, auf der das Aufstellgerät aufgestellt worden ist, eine Verfahrensroutine zur automatischen Zuordnung des Aufstellgeräts zu mindestens einer Kochstelle des induktiven Kochfelds gestartet wird. Auf diese Weise ist es beispielsweise möglich, die Heizspule zunächst mit einer reduzierten elektrischen Leistung anzusteuern, die zwar ausreichend ist, um eine automatische Zuordnung des Aufstellgeräts zu mindestens einer Kochstelle des induktiven Kochfelds vorzunehmen, jedoch keine für einen Zubereitungsvorgang wirksame Aufheizung des Aufstellgeräts bewirkt. Beispielsweise ist dies mittels eines geeigneten Pausen-Leistungs-Verhältnisses realisierbar. Die Heizspule wird erst dann mit der für einen Zubereitungsvorgang ausreichenden elektrischen Leistung bestromt, wenn die Verfahrensroutine eine automatische Zuordnung des Aufstellgeräts zu der Kochstelle, die zu der vorgenannten Heizspule korrespondiert, ergibt. Entsprechend ist die Sicherheit weiter verbessert.An advantageous development of the method provides that, depending on a setting-up event detected by the sensor or a surface on which the set-up device has been set up, detected by the sensor, a process routine for automatically assigning the set-up device to at least one hotplate of the inductive hob is started . In this way, it is possible, for example, to initially control the heating coil with a reduced electrical power, which is sufficient to automatically assign the set-up device to at least one hotplate of the inductive hob, but does not result in effective heating of the set-up device for a preparation process. For example, this can be achieved using a suitable pause-performance ratio. The heating coil is only energized with the electrical power sufficient for a preparation process when the process routine automatically assigns the set-up device to the cooking area corresponds to the aforementioned heating coil. Accordingly, security is further improved.

Die Verfahrensroutine zur automatischen Zuordnung des Aufstellgeräts zu mindestens einer Kochstelle des induktiven Kochfelds ist in weiten geeigneten Grenzen frei wählbar. Eine vorteilhafte Weiterbildung der vorgenannten Ausführungsform des Verfahrens sieht vor, dass in der Verfahrensroutine zur automatischen Zuordnung des Aufstellgeräts zu mindestens einer Kochstelle des induktiven Kochfelds Ausgangssignale des Sensors verwendet werden. Beispielsweise könnten mittels des Sensors detektierte Vibrationen des Aufstellgeräts während der Verfahrensroutine ausgewertet werden, um so die oben genannte Zuordnung zu erzielen.The procedural routine for automatically assigning the set-up device to at least one hotplate of the inductive hob can be freely selected within wide, suitable limits. An advantageous development of the aforementioned embodiment of the method provides that output signals from the sensor are used in the method routine for automatically assigning the set-up device to at least one hotplate of the inductive hob. For example, vibrations of the installation device detected by the sensor could be evaluated during the procedural routine in order to achieve the above-mentioned assignment.

Für die automatische Zuordnung mindestens eines Aufstellgeräts zu mindestens einer Kochstelle des induktiven Kochfelds sind grundsätzlich eine Vielzahl von voneinander verschiedenen Verfahren denkbar.In principle, a large number of different methods are conceivable for the automatic assignment of at least one set-up device to at least one hotplate of the inductive hob.

Beispielsweise sei hier auf die DE 10 2017 112 945 B3 sowie auf die nachveröffentlichten deutschen Patentanmeldungen DE 10 2018 119 953.8 , DE 10 2018 119 965.1 und DE 10 2018 119 969.4 der Anmelderin verwiesen, deren Offenbarungsgehalt jeweils vollumfänglich in die vorliegende Anmeldung inkorporiert ist.For example, here is the DE 10 2017 112 945 B3 as well as the subsequently published German patent applications DE 10 2018 119 953.8 , DE 10 2018 119 965.1 and DE 10 2018 119 969.4 of the applicant, the disclosure content of which is fully incorporated into the present application.

Eine weitere vorteilhafte Weiterbildung des Verfahrens sieht vor, dass in Abhängigkeit von Ausgangssignalen des Sensors eine Füllmenge in dem Aufstellgerät und/oder ein für die Zubereitung des Mediums relevanter Zustand des Mediums detektiert wird/werden. Hierdurch ist die Funktionalität des Sensors weiter gesteigert. Beispielsweise könnte alternativ oder zusätzlich zu der Füllmenge des Mediums in dem Aufstellgerät auch detektiert werden, ob das Medium seinen Siedepunkt erreicht hat. Auch ist eine Erfassung des Siedeeindrucks des Mediums, also des Siedeverhaltens des Mediums, insbesondere in Bezug auf die zugeführte Wärmeleistung, denkbar.A further advantageous development of the method provides that, depending on output signals from the sensor, a filling quantity in the set-up device and/or a state of the medium relevant to the preparation of the medium is/are detected. This further increases the functionality of the sensor. For example, as an alternative or in addition to the filling quantity of the medium in the set-up device, it could also be detected whether the medium has reached its boiling point. It is also conceivable to record the boiling impression of the medium, i.e. the boiling behavior of the medium, in particular in relation to the heat output supplied.

Ferner kann das Verfahren dazu verwendet werden, um eine Geräuschemission bei dem Zubereitungsvorgang zu vermeiden. Beispielsweise, in dem eine Arbeitsfrequenz der Heizspule in Abhängigkeit von Ausgangssignalen des Sensors dahingehend angepasst wird, dass ein Resonanzfall bei dem individuellen Aufstellgerät vermieden wird.Furthermore, the method can be used to avoid noise emissions during the preparation process. For example, in which a working frequency of the heating coil is adjusted depending on output signals from the sensor in such a way that a resonance case in the individual set-up device is avoided.

Eine andere vorteilhafte Weiterbildung des Verfahrens sieht vor, dass die Auswertung von Ausgangssignalen des Sensors in dem Aufstellgerät erfolgt. Auf diese Weise ist es nicht erforderlich, dass die Ausgangssignale des Sensors kontinuierlich oder zumindest in regelmäßigen Zeitabständen von dem Aufstellgerät zu der Kochfeldsteuerung oder einem Drittgerät übertragen werden müssen. Jedoch ist es auch möglich, dass die Auswertung der Ausgangssignale des Sensors zumindest teilweise in der Kochfeldsteuerung und/oder in einem mit der Kochfeldsteuerung in Signalübertragungsverbindung stehenden Drittgerät erfolgt.Another advantageous development of the method provides that the evaluation of output signals from the sensor takes place in the installation device. In this way, it is not necessary for the output signals of the sensor to be transmitted continuously or at least at regular intervals from the set-up device to the hob control or a third-party device. However, it is also possible that the evaluation of the Output signals of the sensor take place at least partially in the hob control and / or in a third-party device that is in signal transmission connection with the hob control.

In der Fig. 1 ist ein Ausführungsbeispiel des erfindungsgemäßen Systems 2 zur Durchführung des erfindungsgemäßen Verfahrens exemplarisch und grob schematisch dargestellt. Das System 2 weist ein induktiv beheiztes Kochfeld, also ein induktives Kochfeld 4, mit insgesamt vier Kochstellen 6 auf. Jeder der Kochstellen 6 ist eine Heizspule 8 zur induktiven Beheizung eines auf der jeweiligen Kochstelle 6 aufgestellten Aufstellgeräts auf dem Fachmann bekannte Weise zugeordnet. Zur Ansteuerung der einzelnen Heizspulen 8 weist das Kochfeld 4 eine Kochfeldsteuerung 10 auf. In einem vollständig ausgeschalteten Zustand befindet sich das induktive Kochfeld 4 in einem Ausschaltmodus A. Ferner weist das System 2 ein als Kochtopf ausgebildetes Aufstellgerät 12 auf. Das Aufstellgerät 12 umfasst eine mit den Heizspulen 8 des Kochfelds 4 induktiv koppelbare Induktionsspule 14 und eine Sendeeinheit 16. Die Sendeeinheit 16 ist bei dem vorliegenden Ausführungsbeispiel als ein Bluetooth-Sender ausgebildet. Ferner umfasst das Aufstellgerät 12 einen Sensor 17 zur Erkennung eines Aufstellereignisses und zur Erkennung der Beschaffenheit einer Unterlage, auf der das Aufstellgerät 12 aufgestellt worden ist. Siehe die Fig. 2. In einer einfacheren Ausführungsform ist es möglich, dass der Sensor lediglich zur Erkennung eines Aufstellereignisses ausgebildet ist.In the Fig. 1 an exemplary embodiment of the system 2 according to the invention for carrying out the method according to the invention is shown as an example and roughly schematically. The system 2 has an inductively heated hob, i.e. an inductive hob 4, with a total of four cooking zones 6. Each of the hotplates 6 is assigned a heating coil 8 for inductive heating of a device placed on the respective hotplate 6 in a manner known to those skilled in the art. To control the individual heating coils 8, the hob 4 has a hob control 10. In a completely switched off state, the inductive hob 4 is in a switch-off mode A. Furthermore, the system 2 has a set-up device 12 designed as a cooking pot. The set-up device 12 includes an induction coil 14 that can be inductively coupled to the heating coils 8 of the hob 4 and a transmitter unit 16. In the present exemplary embodiment, the transmitter unit 16 is designed as a Bluetooth transmitter. Furthermore, the setting-up device 12 includes a sensor 17 for detecting a setting-up event and for detecting the nature of a surface on which the setting-up device 12 has been set up. See this Fig. 2 . In a simpler embodiment, it is possible that the sensor is only designed to detect a set-up event.

Der Sensor 17 ist als ein Beschleunigungssensor ausgebildet, wobei mit dem Beschleunigungssensor auch Schwingungen detektierbar sind. Der Sensor 17 ist in einer ersten Variante an einem Griff 19 des Aufstellgeräts 12 und in einer zweiten Variante an einem Gefäß 21 des Aufstellgeräts 12 zur Aufnahme eines für die Zubereitung mittels des Aufstellgeräts 12 vorgesehenen Mediums angeordnet. Die beiden Varianten für die Positionierung des Sensors 17 an dem Aufstellgerät 12 sind in der Fig. 2 mit den Bezugszeichen 17 und 17' bezeichnet. Nachfolgend wird der Einfachheit halber lediglich das Bezugszeichen 17 verwendet; jedoch sind stets beide vorgenannten Varianten der Positionierung des Sensors 17, 17' gemeint. Zusätzlich weist das Aufstellgerät 12 ein als Bedientaste ausgebildetes Bedienelement 23 zur manuellen Bedienung durch einen Benutzer auf. Das Bedienelement 23 ist bei dem vorliegenden Ausführungsbeispiel dazu vorgesehen, um das Aufstellgerät 12 auszuschalten. Ferner überschneidet sich der Funktionsumfang des Sensors 17 mit dem Funktionsumfang des Bedienelements 23 zumindest teilweise. Dies wird nachfolgend noch näher erläutert. Das Aufstellgerät 12 ist derart ausgebildet und eingerichtet, dass die Sendeeinheit 16 und der Sensor 17 mittels der Induktionsspule 14 mit einer Betriebsenergie versorgbar sind.The sensor 17 is designed as an acceleration sensor, with vibrations also being detectable with the acceleration sensor. In a first variant, the sensor 17 is arranged on a handle 19 of the set-up device 12 and in a second variant on a vessel 21 of the set-up device 12 for receiving a medium intended for preparation by means of the set-up device 12. The two variants for positioning the sensor 17 on the set-up device 12 are in the Fig. 2 designated by reference numbers 17 and 17'. For the sake of simplicity, only reference number 17 is used below; However, both aforementioned variants of the positioning of the sensor 17, 17 'are always meant. In addition, the set-up device 12 has a control element 23 designed as a control button for manual operation by a user on. In the present exemplary embodiment, the control element 23 is intended to switch off the set-up device 12. Furthermore, the functional scope of the sensor 17 overlaps at least partially with the functional scope of the control element 23. This will be explained in more detail below. The installation device 12 is designed and set up in such a way that the transmitting unit 16 and the sensor 17 can be supplied with operating energy by means of the induction coil 14.

Auch weist das Aufstellgerät 12 eine Aufstellgerät-Ausgabeeinheit 26 zur Ausgabe von Informationen an den Benutzer des Aufstellgeräts 12 auf, wobei in Abhängigkeit von einem mittels des Sensors 17 erkannten Aufstellereignisses und/oder einer mittels des Sensors 17 erkannten Unterlage, auf der das Aufstellgerät 12 aufgestellt worden ist, mittels der Aufstellgerät-Ausgabeeinheit 26 eine Information an den Benutzer ausgebbar ist.The setup device 12 also has a setup device output unit 26 for outputting information to the user of the setup device 12, depending on a setup event detected by the sensor 17 and/or a surface detected by the sensor 17 on which the setup device 12 is set up has been, information can be output to the user by means of the set-up device output unit 26.

Alternativ oder zusätzlich dazu kann das induktive Kochfeld in einer anderen Ausführungsform des erfindungsgemäßen Systems eine Kochfeld-Ausgabeeinheit zur Ausgabe von Informationen an den Benutzer des Aufstellgeräts aufweisen, wobei in Abhängigkeit von einem mittels des Sensors erkannten Aufstellereignisses oder einer mittels des Sensors erkannten Unterlage, auf der das Aufstellgerät aufgestellt worden ist, mittels der Kochfeld-Ausgabeeinheit eine Information an den Benutzer ausgebbar ist.Alternatively or additionally, in another embodiment of the system according to the invention, the inductive hob can have a hob output unit for outputting information to the user of the set-up device, depending on a set-up event detected by the sensor or a surface detected by the sensor on which the set-up device has been set up, information can be output to the user by means of the hob output unit.

Das induktive Kochfeld 4 umfasst somit mindestens eine Kochstelle 6, mindestens eine der Kochstelle 6 zugeordnete Heizspule 8 und eine Kochfeldsteuerung 10 zur Ansteuerung der Heizspule 8 in einem Betriebsmodus E des induktiven Kochfelds 4 zur Beheizung eines auf der Kochstelle 6 aufgestellten Aufstellgeräts 12 mit einer Sendeeinheit 16. Die Kochfeldsteuerung 10 ist derart ausgebildet und eingerichtet, dass das induktive Kochfeld 4 zusätzlich in einem Standby-Modus S betreibbar ist, wobei eine Ansteuerung der jeweiligen Heizspule 8 in dem Standby-Modus S nicht ermöglicht ist. Ferner ist die Kochfeldsteuerung 10 derart ausgebildet und eingerichtet, dass das induktive Kochfeld 4 in einem Bereitschaftsmodus B betreibbar ist, wobei das induktive Kochfeld 4 mittels eines von einer Empfangseinheit 18 der Kochfeldsteuerung 10 empfangenen Wecksignals von dem Standby-Modus S in den Bereitschaftsmodus B überführbar ist. Die jeweilige Heizspule 8 ist in dem Bereitschaftsmodus B mittels der Kochfeldsteuerung 10 derart ansteuerbar, dass zum einen eine für einen Zubereitungsvorgang wirksame Beheizung des Aufstellgeräts 12 verhindert ist und zum anderen eine Signalübertragung zwischen der Sendeeinheit 16 und der Empfangseinheit 18 mittels der Heizspule 8 ermöglicht ist.The inductive hob 4 thus comprises at least one hotplate 6, at least one heating coil 8 assigned to the hotplate 6 and a hob control 10 for controlling the heating coil 8 in an operating mode E of the inductive hob 4 for heating a set-up device 12 set up on the hotplate 6 with a transmitting unit 16 The hob control 10 is designed and set up in such a way that the inductive hob 4 can also be operated in a standby mode S, with the respective heating coil 8 not being able to be controlled in the standby mode S. Furthermore, the hob control 10 is designed and set up in such a way that the inductive hob 4 can be operated in a standby mode B, the inductive hob 4 being able to be transferred from standby mode S to standby mode B by means of a wake-up signal received from a receiving unit 18 of the hob control 10 . The respective heating coil 8 can be controlled in the standby mode B by means of the hob control 10 in such a way that, on the one hand, effective heating of the set-up device 12 for a preparation process is prevented and, on the other hand, signal transmission between the transmitting unit 16 and the receiving unit 18 by means of the heating coil 8 is made possible.

Im Nachfolgenden wird das erfindungsgemäße Verfahren gemäß dem vorliegenden Ausführungsbeispiel des Systems 2 anhand der Fig. 1 bis 3 näher erläutert. In der Fig. 3 ist das erfindungsgemäße Verfahren anhand eines Zeit-Signal-Diagramms exemplarisch dargestellt.The method according to the invention according to the present exemplary embodiment of the system 2 is described below using the Fig. 1 to 3 explained in more detail. In the Fig. 3 the method according to the invention is shown as an example using a time-signal diagram.

Das erfindungsgemäße Verfahren funktioniert grundsätzlich wie folgt:
Ein nicht dargestellter Benutzer des Systems 2 stellt das als Kochtopf ausgebildete Aufstellgerät 12 auf die in der Bildebene von Fig. 1 rechts unten angeordnete Kochstelle 6 des Kochfelds 4.The method according to the invention basically works as follows:
A user of the system 2, not shown, places the device 12, which is designed as a cooking pot, on the device in the image plane of Fig. 1 The hotplate 6 of the hob 4 is located at the bottom right.

Sofern sich das induktive Kochfeld 4 in dessen Ausschaltmodus A befindet, beispielsweise in dem das induktive Kochfeld 4 mittels eines nicht dargestellten Hauptschalters vollständig ausgeschaltet worden ist, kann der nicht dargestellte Benutzer das induktive Kochfeld 4 des Systems 2, beispielsweise mittels eines aus dem Stand der Technik bekannten Bedieneingriffs an dem induktiven Kochfeld 4, von dem Ausschaltmodus A direkt in den Betriebsmodus E überführen. Der Benutzer kann dann auf dem Fachmann bekannte Weise einen Zubereitungsvorgang, beispielsweise einen Kochvorgang, mittels des Systems 2 durchführen.If the inductive hob 4 is in its switch-off mode A, for example in which the inductive hob 4 has been completely switched off by means of a main switch, not shown, the user, not shown, can use the inductive hob 4 of the system 2, for example by means of one from the prior art known operating intervention on the inductive hob 4, from the switch-off mode A directly into the operating mode E. The user can then carry out a preparation process, for example a cooking process, using the system 2 in a manner known to those skilled in the art.

Befindet sich das induktive Kochfeld 4 in dessen Standby-Modus S, also in dem das induktive Kochfeld 4 nicht vollständig ausgeschaltet ist, ist eine Ansteuerung der Heizspulen 8 technisch nicht ermöglicht. Dazu müsste der Benutzer das induktive Kochfeld 4 beispielsweise erst auf die oben erläuterte Weise in den Betriebsmodus E überführen.If the inductive hob 4 is in its standby mode S, i.e. in which the inductive hob 4 is not completely switched off, it is not technically possible to control the heating coils 8. To do this, the user would first have to transfer the inductive hob 4 to operating mode E, for example, in the manner explained above.

Jedoch ist das induktive Kochfeld 4 des Systems 2 dazu ausgebildet und eingerichtet, um von dem Standby-Modus S automatisch in den Bereitschaftsmodus B überführt zu werden. Hierfür bedarf es des oben genannten Wecksignals, das mittels der Empfangseinheit 18 der Kochfeldsteuerung 10 empfangen wird. Dieses Wecksignal kann auf voneinander verschiedene Weise erzeugt werden. Bei dem vorliegenden Ausführungsbeispiel ist es vorgesehen, dass das Wecksignal mittels einer Betätigung des an dem Aufstellgerät 12 angeordneten und mit der Sendeeinheit 16 in Signalübertragungsverbindung stehenden Bedienelements 23 oder mittels des an dem Aufstellgerät 12 angeordneten und mit der Sendeeinheit 16 in Signalübertragungsverbindung stehenden Sensors 17 oder mittels einer Betätigung eines an dem induktiven Kochfeld 4 angeordneten und mit der Empfangseinheit 18 der Kochfeldsteuerung 10 in Signalübertragungsverbindung stehenden Bedienelements oder mittels einer Betätigung eines an einem Drittgerät angeordneten und mit der Empfangseinheit 18 der Kochfeldsteuerung 10 in Signalübertragungsverbindung stehenden Bedienelements erzeugt wird. Entsprechend ist das induktive Kochfeld 4 auf sehr unterschiedliche Weise von dem Standby-Modus S in den Bereitschaftsmodus B überführbar, was den Bedienkomfort des Systems 2 steigert. Das Bedienelement des induktiven Kochfelds 4 und das als Smartphone ausgebildete Drittgerät sind nicht dargestellt.However, the inductive hob 4 of the system 2 is designed and set up to be automatically transferred from standby mode S to standby mode B. This requires the above-mentioned wake-up signal, which is received by means of the receiving unit 18 of the hob control 10. This wake-up signal can be generated in different ways. In the present exemplary embodiment, it is provided that the wake-up signal is activated by actuating the control element 23 arranged on the set-up device 12 and in signal transmission connection with the transmitting unit 16 or by means of the sensor 17 arranged on the set-up device 12 and in signal transmission connection with the transmitting unit 16 or by means of an actuation of a control element arranged on the inductive hob 4 and in signal transmission connection with the receiving unit 18 of the hob control 10 or by actuation of a control element arranged on a third-party device and in signal transmission connection with the reception unit 18 of the hob control 10. Accordingly, the inductive hob 4 can be transferred from standby mode S to standby mode B in very different ways, which increases the ease of use of the system 2. The control element of the inductive hob 4 and the third-party device designed as a smartphone are not shown.

Beispielsweise wird das Wecksignal mittels einer Betätigung des an dem Aufstellgerät 12 angeordneten und mit der Sendeeinheit 16 in Signalübertragungsverbindung stehenden Bedienelements 23 des Aufstellgeräts 12 generiert. Hierfür drückt der Benutzer beispielsweise das als Taste ausgebildete Bedienelement 23 des Aufstellgeräts 12 und stellt das Aufstellgerät 12 auf die oben genannte Kochstelle 6 des induktiven Kochfelds 4 auf. Dieser Tastendruck wird mittels der Sendeeinheit 16 des Aufstellgeräts 12 ausgewertet und in das Wecksignal umgewandelt. Das Wecksignal wird dann mittels der Sendeinheit 16, der Heizspule 8 und der Empfangseinheit 18 in die Kochfeldsteuerung 10 übertragen. Die Kochfeldsteuerung 10 überführt das induktive Kochfeld 4 daraufhin von dem Standby-Modus S in den Bereitschaftsmodus B. Die Sendeeinheit 16 wird mittels der durch die Heizspule 8 in die Induktionsspule 14 des auf der dieser Heizspule 8 zugeordneten Kochstelle 6 aufgestellten Aufstellgeräts 12 induzierten Spannung mit Betriebsenergie versorgt.For example, the wake-up signal is activated by actuating the device arranged on the set-up device 12 and in signal transmission connection with the transmitting unit 16 Control element 23 of the installation device 12 is generated. For this purpose, the user presses, for example, the control element 23 of the set-up device 12, which is designed as a button, and places the set-up device 12 on the above-mentioned cooking area 6 of the inductive hob 4. This keystroke is evaluated by the transmitting unit 16 of the set-up device 12 and converted into the wake-up signal. The wake-up signal is then transmitted to the hob control 10 by means of the transmitting unit 16, the heating coil 8 and the receiving unit 18. The hob control 10 then transfers the inductive hob 4 from the standby mode S to the standby mode B. The transmitting unit 16 is supplied with operating energy by means of the voltage induced by the heating coil 8 into the induction coil 14 of the set-up device 12 set up on the hob 6 assigned to this heating coil 8 provided.

Zusätzlich dazu ist es vorgesehen, dass das Wecksignal mittels des an dem Aufstellgerät 12 angeordneten und mit der Sendeeinheit 16 in Signalübertragungsverbindung stehenden Sensors 17 automatisch erzeugbar ist. Beispielsweise wird mittels des Sensors 17 automatisch erkannt, dass das Aufstellgerät 12 von dem Benutzer auf die vorgenannte Kochstelle 6 des induktiven Kochfelds 4 aufgestellt worden ist. Der Sensor 17 hat also zum einen das Vorliegen eines Aufstellereignisses und zum anderen die Unterlage, auf der das Aufstellgerät 12 aufgestellt worden ist, detektiert. Somit ist eine manuelle Betätigung des Bedienelements 23 nicht erforderlich. Jedoch ist es beispielsweise aus Gründen der Redundanz vorteilhaft, dass das Wecksignal auf die oben erläuterte Weise auch mittels des Bedienelements 23 generiert werden kann. Die Auswertung von Ausgangssignalen des Sensors 17 erfolgt bei dem vorliegenden Ausführungsbeispiel direkt in dem Aufstellgerät 12. Die Sendeeinheit 16 und der Sensor 17 werden mittels der durch die Heizspule 8 in die Induktionsspule 14 des auf der dieser Heizspule 8 zugeordneten Kochstelle 6 aufgestellten Aufstellgeräts 12 induzierten Spannung mit Betriebsenergie versorgt.In addition, it is provided that the wake-up signal can be generated automatically by means of the sensor 17 arranged on the set-up device 12 and in signal transmission connection with the transmitting unit 16. For example, the sensor 17 automatically detects that the set-up device 12 has been placed by the user on the aforementioned hotplate 6 of the inductive hob 4. The sensor 17 has, on the one hand, detected the presence of a setting-up event and, on the other hand, the surface on which the setting-up device 12 has been set up. Manual operation of the control element 23 is therefore not necessary. However, for reasons of redundancy, for example, it is advantageous that the wake-up signal can also be generated using the control element 23 in the manner explained above. In the present exemplary embodiment, the evaluation of output signals from the sensor 17 takes place directly in the set-up device 12. The transmitting unit 16 and the sensor 17 are induced by means of the voltage induced by the heating coil 8 into the induction coil 14 of the set-up device 12 set up on the cooking area 6 assigned to this heating coil 8 supplied with operating energy.

Die elektrische Leistung, mit der die Kochfeldsteuerung 10 die Heizspule 8 in dem Bereitschaftsmodus B ansteuert, weist einen Mittelwert von kleiner oder gleich 30 W, bevorzugt kleiner oder gleich 15 W, auf. Ferner weist die elektrische Leistung, mit der die Kochfeldsteuerung 10 die Heizspule 8 in dem Bereitschaftsmodus B ansteuert ein Pausen-Leistungs-Verhältnis von größer oder gleich 1000:1 auf, nämlich eine Bestromung in einem Zeitintervall von 160 µs im Vergleich zu einem Pausenintervall von 2 s. Hierdurch ist zum einen eine für einen Zubereitungsvorgang wirksame Beheizung des Aufstellgeräts 12 verhindert und zum anderen eine Signalübertragung zwischen der Sendeeinheit 16 und der Empfangseinheit 18 mittels der Heizspule 8 ermöglicht. Ferner ist eine Übertragung einer Betriebsenergie von dem induktiven Kochfeld 4 zu dem Aufstellgerät 12, das auf der dieser Heizspule 8 zugeordneten Kochstelle 6 aufgestellt ist, mittels der Heizspule 8 ermöglicht.The electrical power with which the hob control 10 controls the heating coil 8 in standby mode B has an average value of less than or equal to 30 W, preferably less than or equal to 15 W. Furthermore, the electrical power with which the hob control 10 controls the heating coil 8 in the standby mode B has a pause-power ratio of greater than or equal to 1000:1, namely an energization in a time interval of 160 μs compared to a pause interval of 2 s. On the one hand, this prevents effective heating of the set-up device 12 for a preparation process and, on the other hand, enables signal transmission between the transmitting unit 16 and the receiving unit 18 by means of the heating coil 8. Furthermore, a transfer of operating energy from the inductive hob 4 to the set-up device 12, which is set up on the cooking area 6 assigned to this heating coil 8, is made possible by means of the heating coil 8.

Mit der Überführung des induktiven Kochfelds 4 von dessen Standby-Modus S in dessen Bereitschaftsmodus B wird mittels der Kochfeldsteuerung 10 die automatische Zuordnung des Aufstellgeräts 12 zu der oben genannten Kochstelle 6 des induktiven Kochfelds 4 gestartet, die nachfolgend näher erläutert ist. Es wird also in Abhängigkeit von einem mittels des Sensors 17 erkannten Aufstellereignisses und einer mittels des Sensors 17 erkannten Unterlage, auf der das Aufstellgerät 12 aufgestellt worden ist, eine Verfahrensroutine zur automatischen Zuordnung des Aufstellgeräts 12 zu mindestens einer der Kochstellen 6 des induktiven Kochfelds 4 gestartet.When the inductive hob 4 is transferred from its standby mode S to its standby mode B, the hob control 10 starts the automatic assignment of the set-up device 12 to the above-mentioned hotplate 6 of the inductive hob 4, which is explained in more detail below. Depending on an installation event detected by the sensor 17 and a surface on which the installation device 12 has been set up, which is detected by the sensor 17, a process routine for automatically assigning the installation device 12 to at least one of the cooking zones 6 of the inductive hob 4 is started .

Wie oben beschrieben hat der Benutzer des Systems 2 das Kochfeld 4 eingeschaltet und das als Kochtopf ausgebildete Aufstellgerät 12 auf der in der Bildebene von Fig. 1 rechts unten, also rechts vorne, angeordneten Kochstelle 6 des Kochfelds 4 aufgestellt. Nach der Überführung des Kochfelds 4 von dessen Standby-Modus S in dessen Bereitschaftsmodus B zu einem Zeitpunkt t= 0 s, das in der Fig. 3 durch einen Pfeil 24 symbolisiert ist, steuert die Kochfeldsteuerung 10 die Heizspulen 8 der einzelnen Kochstellen 6 nacheinander, also sukzessive, mit deren jeweiligem Leistungsprofil an. Dies ist in der Fig. 3 mittels der Linien a, b, c und d symbolisiert, wobei die Linie a die Ansteuerung der zu der in der Bildebene von Fig. 1 links unten dargestellten Kochstelle 6 korrespondierenden Heizspule 8, die Linie b die Ansteuerung der zu der in der Bildebene von Fig. 1 rechts unten dargestellten Kochstelle 6 korrespondierenden Heizspule 8, die Linie c die Ansteuerung der zu der in der Bildebene von Fig. 1 recht oben dargestellten Kochstelle 6 korrespondierenden Heizspule 8 und die Linie d die Ansteuerung der zu der in der Bildebene von Fig. 1 links oben dargestellten Kochstelle 6 korrespondierenden Heizspule 8 symbolisiert.As described above, the user of the system 2 has switched on the hob 4 and placed the device 12 designed as a cooking pot on the image plane of Fig. 1 The hotplate 6 of the hob 4 is placed at the bottom right, i.e. at the front right. After the hob 4 has been transferred from its standby mode S to its standby mode B at a time t = 0 s, which is in the Fig. 3 is symbolized by an arrow 24, the hob control 10 controls the heating coils 8 of the individual hotplates 6 one after the other, i.e. successively, with their respective power profile. This is in the Fig. 3 symbolized by the lines a, b, c and d, where the line a represents the control of the in the image plane of Fig. 1 The heating coil 8 corresponding to the hotplate 6 shown at the bottom left, the line b the control of the heating coil 8 in the image plane of Fig. 1 The heating coil 8 corresponding to the hotplate 6 shown at the bottom right, the line c the control of the heating coil 8 in the image plane of Fig. 1 The heating coil 8 corresponding to the hotplate 6 shown at the top right and the line d the control of the heating coil 8 in the image plane of Fig. 1 The heating coil 8 corresponding to the hotplate 6 shown at the top left is symbolized.

Da auf der in der Bildebene von Fig. 1 rechts unten dargestellten Kochstelle 6 das als Kochtopf ausgebildete Aufstellgerät 12 aufgestellt ist, wird bei der Ansteuerung der dieser Kochstelle 6 zugeordneten Heizspule 8 eine Spannung von dieser Heizspule 8 in der Induktionsspule 14 des Aufstellgeräts 12 induziert. Siehe hierzu die Linie b in Fig. 3. Aufgrund der in der Induktionsspule 14 induzierten Spannung wird die als Bluetooth-Sender ausgebildete Sendeeinheit 16 des Kochtopfs 12 mit der für ein Senden erforderlichen Betriebsenergie versorgt. Darüber hinaus wird mittels der induzierten Spannung gleichzeitig ein Senden der Sendeeinheit 16 ausgelöst, nämlich das Senden des Antwortsignals 20. Siehe Fig. 1 und 3. Das Antwortsignal 20 umfasst zum einen eine das Aufstellgerät 12 als genau dieses individuelle Aufstellgerät 12 kennzeichnende Identifizierung. Diese Identifizierung des Aufstellgeräts 12 kann beispielsweise für einen Garvorgang auf dem induktiven Kochfeld 4 wichtige Kochtopfeigenschaften aufweisen. Zum anderen umfasst das Antwortsignal 20 mindestens eine zu dem mittels der Heizspule 8 der in der Bildebene von Fig. 1 rechts unten dargestellten Kochstelle 6 in die Induktionsspule 14 des Aufstellgeräts 12 induzierten Leistungsprofil korrelierende Größe. Beispielsweise kann es sich bei dieser Größe um das Leistungsprofil als solches handeln. Denkbar ist jedoch auch, dass diese Größe mindestens eine das Leistungsprofil charakterisierende elektrische und/oder magnetische Größe ist.Since on the in the image plane of Fig. 1 On the hotplate 6 shown at the bottom right, the set-up device 12 designed as a cooking pot is set up, when the heating coil 8 assigned to this hotplate 6 is activated, a voltage is induced by this heating coil 8 in the induction coil 14 of the set-up device 12. See line b in Fig. 3 . Due to the voltage induced in the induction coil 14, the transmitting unit 16 of the cooking pot 12, designed as a Bluetooth transmitter, is supplied with the operating energy required for transmission. In addition, the induced voltage simultaneously triggers transmission of the transmission unit 16, namely the transmission of the response signal 20. See Fig. 1 and 3 . The response signal 20 includes, on the one hand, an identification that identifies the set-up device 12 as exactly this individual set-up device 12. This identification of the set-up device 12 can, for example, have important cooking pot properties for a cooking process on the inductive hob 4. On the other hand, the response signal 20 includes at least one to which the heating coil 8 is located in the image plane Fig. 1 The power profile correlating size induced in the hotplate 6 shown at the bottom right is induced in the induction coil 14 of the set-up device 12. For example, this can be the case Size is about the performance profile as such. However, it is also conceivable that this variable is at least one electrical and/or magnetic variable that characterizes the performance profile.

Das Antwortsignal 20 wird an die Empfangseinheit 18 der Kochfeldsteuerung 10 gesendet. Das von der Empfangseinheit 18 empfangene Antwortsignal 20 wird dann auf dem Fachmann bekannte Weise an die mit der Empfangseinheit 18 signalübertragend verbundene Auswerteeinheit 22 der Kochfeldsteuerung 10 zur Auswertung übertragen. In der Auswerteeinheit 22 wird das Antwortsignal 20 unter anderem mit dem Leistungsprofil der der in der Bildebene von Fig. 1 rechts unten dargestellten Kochstelle 6, auf der das als Kochtopf ausgebildete Aufstellgerät 12 aufgestellt ist, zugeordneten Heizspule 8 verglichen, mit dem diese Heizspule 8 mittels der Kochfeldsteuerung 10 angesteuert worden ist. Da die zu diesem Leistungsprofil korrelierende mindestens eine Größe, die mit dem Antwortsignal 20 von dem Aufstellgerät 12 an die Kochfeldsteuerung 10 übertragen worden ist, mit diesem Leistungsprofil übereinstimmt, wird das Aufstellgerät 12 der in der Bildebene von Fig. 1 rechts unten dargestellten Kochstelle 6 mittels der Auswerteeinheit 22 der Kochfeldsteuerung 10 automatisch zugeordnet. Die Kochfeldsteuerung 10 weiß nun, dass auf dieser Kochstelle 6 genau dieses Aufstellgerät 12 aufgestellt ist und kann auf dieser Basis das induktive Kochfeld 4 automatisch von dessen Bereitschaftsmodus B in dessen Betriebsmodus E überführen und den Garvorgang, also den Zubereitungsvorgang, für dieses individuelle Aufstellgerät 12 mittels der Ansteuerung der dieser Kochstelle 6 zugeordneten Heizspule 8 beispielsweise steuern oder regeln. Das Antwortsignal 20 wird in der Auswerteeinheit 22 auch mit den Leistungsprofilen der übrigen den in der Fig. 1 dargestellten weiteren Kochstellen 6 zugeordneten Heizspulen 8 verglichen, mit denen diese Heizspulen 8 mittels der Kochfeldsteuerung 10 angesteuert worden sind. Da das Aufstellgerät 12 jedoch nicht auf diese Kochstellen 6 und damit nicht über den diesen Kochstellen 6 zugeordneten Heizspulen 8 aufgestellt ist, führt die jeweilige Ansteuerung dieser Heizspulen 8 nicht zu einem zu einem dieser Leistungsprofile korrespondierenden Antwortsignal.The response signal 20 is sent to the receiving unit 18 of the hob control 10. The response signal 20 received by the receiving unit 18 is then transmitted in a manner known to those skilled in the art to the evaluation unit 22 of the hob control 10, which is connected to the receiving unit 18 in a signal-transmitting manner, for evaluation. In the evaluation unit 22, the response signal 20 is, among other things, with the power profile of the in the image plane of Fig. 1 Cooking area 6 shown at the bottom right, on which the set-up device 12 designed as a cooking pot is placed, is compared to the heating coil 8 assigned to it, with which this heating coil 8 was controlled by means of the hob control 10. Since the at least one variable correlating to this performance profile, which has been transmitted with the response signal 20 from the set-up device 12 to the hob control 10, corresponds to this performance profile, the set-up device 12 is in the image plane of Fig. 1 The hotplate 6 shown at the bottom right is automatically assigned to the hob control 10 by means of the evaluation unit 22. The hob control 10 now knows that exactly this set-up device 12 is set up on this hotplate 6 and can, on this basis, automatically transfer the inductive hob 4 from its standby mode B to its operating mode E and carry out the cooking process, i.e. the preparation process, for this individual set-up device 12 by means of For example, control or regulate the control of the heating coil 8 assigned to this hotplate 6. The response signal 20 is also combined in the evaluation unit 22 with the performance profiles of the remaining ones in the Fig. 1 illustrated further cooking zones 6 associated heating coils 8 compared with which these heating coils 8 were controlled by means of the hob control 10. However, since the set-up device 12 is not set up on these hotplates 6 and therefore not above the heating coils 8 assigned to these hotplates 6, the respective control of these heating coils 8 does not lead to a response signal corresponding to one of these power profiles.

Wie aus Fig. 3 weiter ersichtlich ist, erfolgen auf die in der Zeitachse links dargestellten Ansteuerungen der übrigen Heizspulen 8 des induktiven Kochfelds 4 keine Antwortsignale von etwaigen anderen Aufstellgeräten.How out Fig. 3 As can also be seen, there are no response signals from any other set-up devices to the activation of the remaining heating coils 8 of the inductive hob 4 shown in the time axis on the left.

Gemäß den vorgenannten Ausführungen war die Zuordnung des Aufstellgeräts 12 zu der in der Bildebene von Fig. 1 rechts unten dargestellten Kochstelle 6 und damit zu der zu dieser Kochstelle 6 korrespondierenden Heizspule 8 erfolgreich, so dass die Kochfeldsteuerung 10 das induktive Kochfeld 4 des Systems 2 automatisch von dem Bereitschaftsmodus B in den Betriebsmodus E überführt. Der Benutzer kann beispielsweise an dem induktiven Kochfeld 4 auf dem Fachmann bekannte Weise eine Leistungseinstellung für diese Heizspule 8 vornehmen.According to the aforementioned statements, the assignment of the installation device 12 was to that in the image plane of Fig. 1 hotplate 6 shown at the bottom right and thus to the heating coil 8 corresponding to this hotplate 6 successfully, so that the hob control 10 automatically transfers the inductive hob 4 of the system 2 from standby mode B to operating mode E. The user can, for example, use the inductive hob 4 Make a power setting for this heating coil 8 in a manner known to those skilled in the art.

Sofern eine automatische Zuordnung des Aufstellgeräts 12 zu einer der Kochstellen 6 des induktiven Kochfelds 4 des Systems 2 nicht erfolgt, beispielsweise, weil das Aufstellgerät 12 auf keiner der Kochstellen 6 des induktiven Kochfelds 4 aufgestellt worden ist, überführt die Kochfeldsteuerung 10 das induktive Kochfeld 4, beispielsweise nach Ablauf einer vorher festgelegten und in der Kochfeldsteuerung 10 abgespeicherten Zeitspanne, automatisch von dem Bereitschaftsmodus B zurück in den Standby-Modus S.If the set-up device 12 is not automatically assigned to one of the hotplates 6 of the inductive hob 4 of the system 2, for example because the set-up device 12 has not been set up on any of the hotplates 6 of the inductive hob 4, the hob control 10 transfers the inductive hob 4, For example, after a predetermined period of time stored in the hob control 10 has elapsed, automatically from standby mode B back to standby mode S.

Eine automatische Zuordnung des Aufstellgeräts 12 zu einer der Kochstellen 6 könnte beispielsweise deshalb nicht möglich sein, weil das Aufstellgerät 12 beispielsweise auf einem nicht dargestelltenTopfuntersetzer aus Holz auf einem Tisch aufgestellt worden ist. In diesem Fall kann es vorgesehen sein, dass in Abhängigkeit von dem mittels des Sensors 17 erkannten Aufstellereignis und der mittels des Sensors 17 erkannten Unterlage, auf der das Aufstellgerät 12 aufgestellt worden ist, mittels der Aufstellgerät-Ausgabeeinheit 26 eine Information an den Benutzer ausgegeben wird. Beispielsweise ist es denkbar, dass bei einem noch Restwärme aufweisenden Aufstellgerät 12 als Information ein Warnsignal ausgegeben wird, wenn mittels des Sensors 17 erkannt worden ist, dass es sich bei der Unterlage, auf der das Aufstellgerät 12 aufgestellt worden ist, nicht um eine der Kochstellen 6 des induktiven Kochfelds 4, sondern um eine Unterlage aus Holz oder Stoff, beispielsweise den oben genannten Topfuntersetzer, handelt. Eine Information an den Benutzer kann auch für den Fall erfolgen, wenn mittels des Sensors 17 das Aufstellen des Aufstellgeräts 12 auf das induktive Kochfeld 4 erkannt worden ist.An automatic assignment of the set-up device 12 to one of the cooking areas 6 might not be possible, for example, because the set-up device 12 has been set up on a table, for example on a wooden trivet (not shown). In this case, it can be provided that information is output to the user by means of the setting-up device output unit 26, depending on the setting-up event recognized by means of the sensor 17 and the surface on which the setting-up device 12 has been set up, recognized by the sensor 17 . For example, it is conceivable that in the case of a set-up device 12 that still has residual heat, a warning signal is issued as information if it has been recognized by the sensor 17 that the surface on which the set-up device 12 has been set up is not one of the cooking zones 6 of the inductive hob 4, but rather a base made of wood or fabric, for example the pot trivet mentioned above. Information can also be provided to the user if the positioning of the device 12 on the inductive hob 4 has been detected by means of the sensor 17.

Analog zu der oben erläuterten Überführung des induktiven Kochfelds 4 von dessen Ausschaltmodus A in dessen Betriebsmodus E ist es bei dem vorliegenden Ausführungsbeispiel auch möglich, das induktive Kochfeld 4 von dem Standby-Modus S direkt in den Betriebsmodus E zu überführen.Analogous to the above-explained transfer of the inductive hob 4 from its switch-off mode A to its operating mode E, it is also possible in the present exemplary embodiment to transfer the inductive hob 4 from the standby mode S directly to the operating mode E.

Bei dem vorliegenden Ausführungsbeispiel werden die einzelnen Heizspulen 8 des Kochfelds 4 in dem Bereitschaftsmodus B und in dem Betriebsmodus E des induktiven Kochfelds 4 in vorher festgelegten Zeitabständen unabhängig von einem Wecksignal kontinuierlich sukzessive angesteuert. Bei jedem Durchlauf der Ansteuerung der einzelnen Heizspulen 8 mittels der Kochfeldsteuerung 10 werden immer alle vier Heizspulen 8 des Kochfelds 4 sukzessive angesteuert. Nach dem in der Fig. 3 links dargestellten Durchlauf beginnt ab t= 3,5 s ein erneuter Durchlauf mit der sukzessiven Ansteuerung der Heizspulen 8 des induktiven Kochfelds 4. Bei dem vorliegenden Ausführungsbeispiel erfolgt die Ansteuerung der einzelnen Heizspulen 8 des induktiven Kochfeldes 4 mit deren jeweiligem Leistungsprofil in dem Bereitschaftsmodus B und in dem Betriebsmodus E des induktiven Kochfelds 4 also in Abhängigkeit mindestens eines vorher festgelegten Zeitintervalls kontinuierlich.In the present exemplary embodiment, the individual heating coils 8 of the hob 4 are continuously and successively activated in the standby mode B and in the operating mode E of the inductive hob 4 at predetermined time intervals, independently of a wake-up signal. Each time the individual heating coils 8 are controlled using the hob control 10, all four heating coils 8 of the hob 4 are successively activated. After that in the Fig. 3 In the cycle shown on the left, a new cycle begins from t = 3.5 s with the successive control of the heating coils 8 of the inductive hob 4. In the present exemplary embodiment, the individual heating coils 8 of the inductive hob 4 are activated with their respective power profile in standby mode B and in the operating mode E of the inductive Hob 4 is therefore continuous depending on at least a predetermined time interval.

Die automatische Überführung des induktiven Kochfelds 4 von dessen Bereitschaftsmodus B in dessen Betriebsmodus E erfolgt zum einen durch den oben bereits erläuterten Bedieneingriff und damit analog zu der Überführung von dem Ausschaltmodus A in den Betriebsmodus E. Zum anderen erfolgt die Überführung von dem Bereitschaftsmodus B in den Betriebsmodus E automatisch durch eine erfolgreiche Zuordnung von dem Aufstellgerät 12 auf der einen Seite zu einer der Kochstellen 6 des induktiven Kochfelds 4 auf der anderen Seite.The automatic transfer of the inductive hob 4 from its standby mode B to its operating mode E takes place on the one hand through the operating intervention already explained above and thus analogous to the transfer from the switch-off mode A to the operating mode E. On the other hand, the transfer takes place from the standby mode B to the Operating mode E automatically through a successful assignment of the set-up device 12 on one side to one of the cooking zones 6 of the inductive hob 4 on the other side.

Die Erfindung ist nicht auf das vorliegende Ausführungsbeispiel begrenzt. Beispielsweise kann es vorgesehen sein, dass in Abhängigkeit von Ausgangssignalen des Sensors eine Füllmenge in dem Aufstellgerät und/oder ein für die Zubereitung des Mediums relevanter Zustand des Mediums detektiert wird/werden. Hierdurch ist die Funktionalität des Sensors weiter gesteigert. Beispielsweise könnte alternativ oder zusätzlich zu der Füllmenge des Mediums in dem Aufstellgerät auch detektiert werden, ob das Medium seinen Siedepunkt erreicht hat. Auch ist eine Erfassung des Siedeeindrucks des Mediums, also des Siedeverhaltens des Mediums, insbesondere in Bezug auf die Dichte der zugeführten Wärmeleistung, denkbar. Ferner kann das erfindungsgemäße Verfahren dazu verwendet werden, um eine Geräuschemission bei dem Zubereitungsvorgang zu vermeiden. Beispielsweise, in dem eine Arbeitsfrequenz der Heizspule in Abhängigkeit von Ausgangssignalen des Sensors dahingehend angepasst wird, dass ein Resonanzfall bei dem individuellen Aufstellgerät vermieden wird. Darüber hinaus ist es auch möglich, dass die Auswertung der Ausgangssignale des Sensors zumindest teilweise in der Kochfeldsteuerung und/oder in einem mit der Kochfeldsteuerung in Signalübertragungsverbindung stehenden Drittgerät erfolgt.The invention is not limited to the present exemplary embodiment. For example, it can be provided that, depending on output signals from the sensor, a filling quantity in the set-up device and/or a state of the medium relevant to the preparation of the medium is/are detected. This further increases the functionality of the sensor. For example, as an alternative or in addition to the filling quantity of the medium in the set-up device, it could also be detected whether the medium has reached its boiling point. It is also conceivable to record the boiling impression of the medium, i.e. the boiling behavior of the medium, in particular in relation to the density of the heat output supplied. Furthermore, the method according to the invention can be used to avoid noise emissions during the preparation process. For example, in which a working frequency of the heating coil is adjusted depending on output signals from the sensor in such a way that a resonance case in the individual set-up device is avoided. In addition, it is also possible for the output signals of the sensor to be evaluated at least partially in the hob control and/or in a third-party device that is in signal transmission connection with the hob control.

Eine zu dem Ausführungsbeispiel alternative Ausführungsform der automatischen Zuordnung mindestens eines Aufstellgeräts zu mindestens einer Kochstelle des induktiven Kochfelds sieht beispielsweise vor, dass die Kochfeldsteuerung die Heizspulen mit mindestens einem Zuordnungssignal ansteuert und eine Messeinheit des Aufstellgeräts eine zu dem in die Induktionsspule induzierten Zuordnungssignal korrelierende Vibration des Aufstellgeräts detektiert und die Sendeeinheit ein das Aufstellgerät identifizierendes und zu der detektierten Vibration des Aufstellgeräts korrelierendes Antwortsignal an die Empfangseinheit der Kochfeldsteuerung oder eines mit der Kochfeldsteuerung in Signalübertragungsverbindung stehenden Drittgeräts sendet und das Antwortsignal in einer mit der Empfangseinheit signalübertragend verbundenen Auswerteeinheit der Kochfeldsteuerung oder dem Drittgerät mit dem Zuordnungssignal der mindestens einen Heizspule dieser Kochstelle verglichen wird und in Abhängigkeit dieses Vergleichs das identifizierte Aufstellgerät dieser Kochstelle zugeordnet wird. Beispielsweise ist es in diesem Zusammenhang möglich, dass in der Verfahrensroutine zur automatischen Zuordnung des Aufstellgeräts zu mindestens einer Kochstelle des induktiven Kochfelds Ausgangssignale des Sensors verwendet werden. Beispielsweise könnten mittels des Sensors detektierte Vibrationen des Aufstellgeräts während der Verfahrensroutine ausgewertet werden, um so die oben genannte Zuordnung zu erzielen. Entsprechend wäre eine Messeinheit zusätzliche zu dem Sensor nicht zwingend erforderlich.An alternative embodiment to the exemplary embodiment of the automatic assignment of at least one set-up device to at least one hotplate of the inductive hob provides, for example, that the hob control controls the heating coils with at least one assignment signal and a measuring unit of the set-up device produces a vibration of the set-up device that correlates with the assignment signal induced in the induction coil detected and the transmitting unit sends a response signal identifying the set-up device and correlating to the detected vibration of the set-up device to the receiving unit of the hob control or a third-party device in signal transmission connection with the hob control and the response signal in an evaluation unit of the hob control or the third-party device connected to the receiving unit in a signal-transmitting manner Assignment signal of the at least one heating coil of this hotplate is compared and depending on this comparison, the identified set-up device is assigned to this cooking area. For example, in this context it is possible for output signals from the sensor to be used in the process routine for automatically assigning the set-up device to at least one hotplate of the inductive hob. For example, vibrations of the installation device detected by the sensor could be evaluated during the procedural routine in order to achieve the above-mentioned assignment. Accordingly, a measuring unit in addition to the sensor would not be absolutely necessary.

Jedoch sind auch andere Ausführungsformen der automatischen Zuordnung mindestens eines Aufstellgeräts zu mindestens einer Kochstelle des induktiven Kochfelds denkbar.However, other embodiments of the automatic assignment of at least one set-up device to at least one hotplate of the inductive hob are also conceivable.
