- An advantage of limiting the maximum temperature or restricting the maximum temperature rise by regulating the power supply to the heating element of a hob is to be seen that even with reduced monitoring capacity of the user of the hob as high as possible reliability of the cooking zone of the hob is possible. If the user with limited perception uses the hob presented here, the risk of fire is significantly lower compared to using a conventional hob. The ease of use is substantially improved over a conventional cooking field requiring constant monitoring.
- the protection device may include an input interface for inputting and storing a modification parameter, and the protection device may be configured to determine the modified control parameter using the modification parameter.

- the input interface may be formed by a plug for connecting a cable.
- a plug for connecting a cable Such an embodiment of the present invention offers the advantage of easy adjustment of the modification parameter for technically trained persons, for example by using a corresponding programming device, which is connected via the connector with the data cable to the input interface. In this way, for example, an employee of the technical support during installation or Maintaining the hob very quickly on site, set the modification parameter to a value that matches the operator's ability to monitor the operation of the hob.
- the modification parameter is particularly safe to protect the modification parameter against inadvertent or unauthorized alteration if the input interface is formed by a radio receiver.
- a radio transmitter matching the radio receiver is required to change or set the modification parameter, so that it can be considered with high certainty that the modification parameter is selectively changed or set only by authorized persons by operation of the radio transmitter.
- the input interface can be arranged according to an embodiment of the present invention on a side facing away from the control element of the hob.
- complex position changes of the cooktop or of parts of the cooktop would have to take place in this case, which are not to be expected in the usual operation of the cooktop and consequently with high certainty not by an operator of the cooktop, who has a limited perception , are to be expected.
- the protection device may be configured to output an optical and / or acoustic test signal, a period of time after the test signal is issued for detecting a response signal by a user of the hob and to determine the modified control parameter using the detected time period.
- a supply of the heating element can be influenced by electric current.
- a supply of the electrically adjustable valve with electric current, a gas flow rate can be influenced.
- a gas flow rate can be influenced.
- the invention can be used not only in electric cooktops but also in gas-fired cooktops, whereby the present approach also in other hob types such as a potentially very dangerous gas cooktop, which is an open in operation Flame has, can be used. Operational safety of such hob types can be improved by the proposed approach, so that eventually an exchange of such a dangerous gas hob can be avoided by an operator with no longer so high monitoring capacity.
- the cooktop may further comprise a sensor for direct or indirect determination of a current heat output by the heating element, which is connected to the heating element and the protection device to a control loop for adjusting a power supply to the heating element.

- a temperature increase of the heating element or the cooking zone can be reduced, for example, if the modified control parameter represents an energy supply H to the heating element 207, which instead of on the solid curve in Fig. 3 on the in Fig. 3 dashed lines shown for a reduced temporal temperature increase 335. In this case, a lower energy H than the actual desired by the control parameter 215 user input H to the heating element 207 is allowed, so that consequently the temperature rise of the heating element 207 is lower.
- the characteristic curve for the defined reduced temperature rise 335 can be carried out, for example, by multiplying the control parameter 215 by a factor of less than one, this factor being in the range of Control parameters that represent a low temperature T of the heating element 207 may be greater than for a control parameter representing a higher temperature T of the heating element 207.

- the response time 360 in terms of the time delay between the output of the test signal 340 and the receipt of the response signal 350 transmits the attention checking device 330 to the protection device 210.
- the protection device 210 also reads out the response time 360 from the attention checking unit 330 in addition to the modification parameter 227 and additionally makes the determination of the modified control parameter 230 based on the determined response time 360. This makes it possible to monitor whether the user's abilities to monitor the cooktop have subsided, so that, if necessary, an automatic adaptation of the modification parameter is required. This adaptation can be done, for example, such that the modification parameter is changed so that the heating element may assume an even lower maximum temperature or the maximum allowable temperature rise of the heating element is further reduced.
- Fig. 4 13 shows a flowchart of a method 400 for controlling a power supply to a heating element 207 of a hob 110.

Abstract
Description
Die vorliegende Erfindung bezieht sich auf ein Kochfeld gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a hob according to the preamble of
Bei Haushaltsgeräten ist besonders auch die Benutzung von Kochfeldern aufgrund der hohen Wärmeentwicklung sowie der damit verbundenen Brandgefahr und der Notwendigkeit einer stetigen Überwachung aller Betriebsparameter mit Risiken behaftet. Haushaltsgeräte müssen nicht nur durch einen Nutzer bedient sondern auch in gewissem Umfang überwacht werden. Dies erfolgt zu dem Zweck, dass der Betrieb des Gerätes möglichst in der vom Nutzer gewünschten Weise erfolgt. Die Überwachung setzt jedoch voraus, dass der Nutzer des Gerätes auch in der Lage ist, die geforderte Überwachung eigenverantwortlich und schritthaltend, d. h. in Echtzeit, durchzuführen. Beeinträchtigungen des Überwachungsvermögens seitens des Nutzers, wie beispielsweise ein reduziertes Sehvermögen, Hörvermögen, Riechvermögen, Temperaturempfinden, Zeitgefühl usw., können einen Betrieb des Haushaltsgerätes daher gefahrengeneigt machen.In the case of household appliances, the use of cooktops is particularly subject to risks due to the high heat development and the associated risk of fire and the necessity of continuous monitoring of all operating parameters. Domestic appliances must not only be operated by a user but also be monitored to some extent. This is done for the purpose that the operation of the device is possible in the manner desired by the user. However, the monitoring assumes that the user of the device is also able to perform the required monitoring on his own responsibility and keeping pace, d. H. in real time, perform. Impairments of the user's ability to monitor, such as reduced vision, hearing, smelling ability, temperature sensation, sense of time, etc., may render the operation of the household appliance prone to danger.

Die vorliegende Erfindung schafft ein Kochfeld mit einem Heizelement und einem Bedienelement zur Eingabe eines Steuerparameters für ein Heizelement zumindest einer Kochzone. Weiterhin umfasst das Kochfeld eine Schutzvorrichtung zur Modifizierung des Steuerparameters und zur Ausgabe eines modifizierten Steuerparameters an das Heizelement, um das Heizelement derart anzusteuern, dass das Heizelement höchstens bis zu einer definierten Maximaltemperatur aufgeheizt wird und/oder dass das Heizelement höchstens mit einem definierten zeitlichen Temperaturgradienten aufgeheizt wird.The present invention provides a cooktop with a heating element and a control element for inputting a control parameter for a heating element of at least one cooking zone. Furthermore, the hob comprises a protective device for modifying the control parameter and for outputting a modified control parameter to the heating element in order to control the heating element such that the heating element is heated at most up to a defined maximum temperature and / or the heating element is heated at most with a defined temporal temperature gradient becomes.
Ferner schafft die vorliegende Erfindung ein Verfahren zur Steuerung einer Energiezufuhr an ein Heizelement eines Kochfeldes. Das Verfahren umfasst die folgenden Schritte:
- Empfangen eines Steuerparameters für ein Heizelement zumindest einer Kochzone eines Kochfeldes von einem Bedienelement für das Heizelement der Kochzone;
- Einlesen zumindest eines Modifikationsparameters aus einer Eingabeschnittstelle;
- Bestimmen eines modifizierten Steuerparameters unter Verwendung des Steuerparameters und des Modifikationsparameters; und
- Ausgeben des modifizierten Steuerparameters an das Heizelement zur Steuerung einer Energiezufuhr des Heizelementes der Kochzone, um das Heizelement derart anzusteuern, dass das Heizelement höchstens bis zu einer definierten Maximaltemperatur aufgeheizt wird und/oder dass das Heizelement höchstens mit einem definierten zeitlichen Temperaturgradienten aufgeheizt wird.
- Receiving a control parameter for a heating element of at least one cooking zone of a hob from a control element for the heating element of the cooking zone;

Der vorliegenden Erfindung liegt die Erkenntnis zugrunde, dass die Ansteuerung eines Heizelementes einer Kochzone des Kochfeldes so modifiziert werden kann, dass nicht mehr zu hohe und somit gefährliche Temperaturen im oder am Kochgeschirr erreicht werden können und/oder sich das Kochgeschirr nicht mehr zu schnell aufheizt. Durch diese Beschränkung der Maximaltemperatur und/oder Beschränkung des maximalen Temperaturanstiegs kann eine Anpassung des Betriebsverhaltens der Kochzone an das Überwachungsvermögen des Benutzers erreicht werden. Ein Vorteil der Beschränkung der Maximaltemperatur oder der Beschränkung des maximalen Temperaturanstiegs durch eine Regulierung der Energiezufuhr an das Heizelement eines Kochfeldes ist darin zu sehen, dass nun auch bei vermindertem Überwachungsvermögen des Benutzers des Kochfeldes eine möglichst hohe Betriebssicherheit der Kochzone des Kochfeldes möglich wird. Wenn der Benutzer mit eingeschränkter Wahrnehmungsfähigkeit das hier vorgestellte Kochfeld benutzt, ist die Brandgefahr, verglichen mit der Benutzung eines herkömmlichen Kochfeldes, deutlich geringer. Der Bedienkomfort ist gegenüber einem stetige Überwachung erfordernden herkömmlichen Kochfeld wesentlich verbessert.The present invention is based on the finding that the control of a heating element of a cooking zone of the hob can be modified so that not too high and thus dangerous temperatures can be reached in or on the cookware and / or the cookware does not heat up too quickly.

An advantage of limiting the maximum temperature or restricting the maximum temperature rise by regulating the power supply to the heating element of a hob is to be seen that even with reduced monitoring capacity of the user of the hob as high as possible reliability of the cooking zone of the hob is possible. If the user with limited perception uses the hob presented here, the risk of fire is significantly lower compared to using a conventional hob. The ease of use is substantially improved over a conventional cooking field requiring constant monitoring.
Gemäß einer Ausführungsform der vorliegenden Erfindung kann die Schutzvorrichtung eine Eingabeschnittstelle zur Eingabe und Speicherung eines Modifikationsparameters aufweisen, und die Schutzvorrichtung ausgebildet sein, den modifizierten Steuerparameter unter Verwendung des Modifikationsparameters zu bestimmen. Eine derartige Ausführungsform der vorliegenden Erfindung bietet den Vorteil, dass eine Einstellung des Modifikationsparameters je nach Erfordernis des Bedieners möglich wird, so dass bei verschiedenen Kochfeldern für unterschiedliche Bediener auch unterschiedliche Modifikationsparameter verwendet werden können. Dies ermöglicht eine individuelle Einstellbarkeit des Kochfeldes auf die jeweiligen Fähigkeiten des Bedieners zur Überwachung des Betriebs des Kochfeldes.According to an embodiment of the present invention, the protection device may include an input interface for inputting and storing a modification parameter, and the protection device may be configured to determine the modified control parameter using the modification parameter. Such an embodiment The present invention offers the advantage that an adjustment of the modification parameter becomes possible depending on the requirement of the operator, so that different modification parameters can also be used for different cooktops for different operators. This allows individual adjustment of the hob to the respective capabilities of the operator to monitor the operation of the hob.
Günstig ist es ferner, wenn die Eingabeschnittstelle als eine manuelle Eingabeschnittstelle ausgebildet ist. Eine derartige Ausführungsform der vorliegenden Erfindung bietet den Vorteil einer einfachen Einstellbarkeit oder Veränderbarkeit des Modifikationsparameters.It is also advantageous if the input interface is designed as a manual input interface. Such an embodiment of the present invention offers the advantage of easy adjustability or variability of the modification parameter.
Hierbei kann die manuelle Eingabeschnittstelle durch ein Drehrad oder einen Drehschalter gebildet sein. Eine derartige Ausführungsform der vorliegenden Erfindung bietet den Vorteil, dass sich eine solche manuelle Eingabeschnittstelle auch durch technisch nicht versierte Personen einfach betätigen lässtHere, the manual input interface can be formed by a rotary knob or a rotary switch. Such an embodiment of the present invention offers the advantage that such a manual input interface can also be operated easily by technically non-skilled persons
Um zu verhindern, dass eine Veränderung des Modifikationsparameters unabsichtlich erfolgt, oder dass eine zur Einstellung oder Veränderung des Modifikationsparameters nicht befugte Person die manuelle Eingabeschnittstelle betätigt, kann die manuelle Eingabeschnittstelle eine Sicherungseinrichtung gegen ein unbefugtes oder unbeabsichtigtes Verstellen des Modifikationsparameters aufweisen. Diese Sicherungseinrichtung kann beispielsweise eine einfache Rastklinke zur Fixierung einer an der manuellen Eingabeschnittstelle eingestellten Position sein. Alternativ oder zusätzlich kann beispielweise auch ein Schloss vorgesehen sein, so dass die Einstellung oder Änderung des Modifikationsparameters über die manuelle Schnittstelle nur erfolgen kann, wenn das Schloss zuvor durch einen ein passender Schlüssel geöffnet wurde.In order to prevent an alteration of the modification parameter from occurring unintentionally, or that a person unauthorized to set or change the modification parameter actuates the manual input interface, the manual input interface may comprise a safeguard against unauthorized or unintentional adjustment of the modification parameter. This securing device can be, for example, a simple latch for fixing a position set at the manual input interface. Alternatively or additionally, for example, a lock may be provided, so that the adjustment or modification of the modification parameter via the manual interface can only be done if the lock was previously opened by a matching key.
Gemäß einer weiteren Ausführungsform der vorliegenden Erfindung kann die Eingabeschnittstelle durch einen Stecker zum Anschluss eines Kabels gebildet sein. Eine derartige Ausführungsform der vorliegenden Erfindung bietet den Vorteil einer einfachen Einstellung des Modifikationsparameters für technisch geschulte Personen, beispielweise unter Verwendung eines entsprechenden Programmiergerätes, welches über den Stecker mit dem Datenkabel an die Eingabeschnittstelle angeschlossen wird. Auf diese Weise kann beispielsweise ein Mitarbeiter des technischen Kundendienstes bei der Installation oder Wartung des Kochfeldes sehr schnell vor Ort den Modifikationsparameter auf einen Wert setzen, der den Fähigkeiten des Bedieners an die Überwachung des Betriebs des Kochfeldes entspricht.According to another embodiment of the present invention, the input interface may be formed by a plug for connecting a cable. Such an embodiment of the present invention offers the advantage of easy adjustment of the modification parameter for technically trained persons, for example by using a corresponding programming device, which is connected via the connector with the data cable to the input interface. In this way, for example, an employee of the technical support during installation or Maintaining the hob very quickly on site, set the modification parameter to a value that matches the operator's ability to monitor the operation of the hob.
Besonders sicher kann der Modifikationsparameter gegen unabsichtliche oder unbefugte Veränderung geschützt werden, wenn die Eingabeschnittstelle durch einen Funkempfänger gebildet ist. In diesem Fall ist ein zum Funkempfänger passender Funksender erforderlich, um den Modifikationsparameter zu verändern oder einzustellen, so dass mit hoher Sicherheit davon ausgegangen werden kann, dass der Modifikationsparameter nur von autorisierten Personen gezielt durch Betätigung des Funksenders verändert oder eingestellt wird.It is particularly safe to protect the modification parameter against inadvertent or unauthorized alteration if the input interface is formed by a radio receiver. In this case, a radio transmitter matching the radio receiver is required to change or set the modification parameter, so that it can be considered with high certainty that the modification parameter is selectively changed or set only by authorized persons by operation of the radio transmitter.
Um eine ungewollte oder unbefugte Veränderung oder Einstellung des Modifikationsparameters möglichst sicher zu verhindern, kann die Eingabeschnittstelle gemäß einer Ausführungsform der vorliegenden Erfindung auf einer dem Bedienelement abgewandten Seite des Kochfeldes angeordnet sein. Um eine Veränderung des Modifikationsparameters durchzuführen, müssten in diesem Fall aufwändige Positionsänderungen des Kochfeldes oder von Teilen des Kochfeldes erfolgen, die im üblichen Betrieb des Kochfeldes nicht zu erwarten sind und folglich mit hoher Sicherheit auch nicht von einem Bediener des Kochfeldes, der ein eingeschränktes Wahrnehmungsvermögen hat, zu erwarten sind.In order to prevent an unwanted or unauthorized change or adjustment of the modification parameter as safely as possible, the input interface can be arranged according to an embodiment of the present invention on a side facing away from the control element of the hob. In order to carry out a change of the modification parameter, complex position changes of the cooktop or of parts of the cooktop would have to take place in this case, which are not to be expected in the usual operation of the cooktop and consequently with high certainty not by an operator of the cooktop, who has a limited perception , are to be expected.
Um eine aktuelle Wahrnehmungsfähigkeit des Bedieners und somit die Fähigkeit des Bedieners zur Überwachung des Betriebs des Kochfeldes zu berücksichtigen, kann gemäß einer Ausführungsform der vorliegenden Erfindung die Schutzvorrichtung ausgebildet sein, um ein optisches und/oder akustisches Prüfsignal auszugeben, eine Zeitspanne nach Ausgabe des Prüfsignals bis zur Eingabe eines Reaktionssignals durch einen Benutzer des Kochfeldes zu erfassen und den modifizierten Steuerparameter unter Verwendung der erfassten Zeitspanne zu ermitteln.In order to take into account a current perception ability of the operator and thus the ability of the operator to monitor the operation of the hob, according to one embodiment of the present invention, the protection device may be configured to output an optical and / or acoustic test signal, a period of time after the test signal is issued for detecting a response signal by a user of the hob and to determine the modified control parameter using the detected time period.
Bei einem Kochfeld, bei dem das zumindest eine Heizelement durch ein elektrisches Heizelement gebildet ist, kann gemäß einer besonderen Ausführungsform der vorliegenden Erfindung mittels des modifizierten Steuerparameters eine Versorgung des Heizelementes mit elektrischem Strom beeinflussbar sein. Eine solche Ausführungsform der vorliegenden Erfindung bietet den Vorteil einer besonders einfachen Steuerung der Heizwirkung des Heizelementes für eine Kochzone.In a hob in which the at least one heating element is formed by an electric heating element, according to a particular embodiment of the present invention by means of the modified control parameter, a supply of the heating element can be influenced by electric current. Such an embodiment of the present invention Invention provides the advantage of a particularly simple control of the heating effect of the heating element for a cooking zone.
Bei einem anderen Kochfeld, bei dem das zumindest eine Heizelement durch ein gasbetriebenes Heizelement mit einem elektrisch einstellbaren Gaszufuhrventil ausgebildet ist, kann gemäß einer anderen Ausführungsform der vorliegenden Erfindung mittels des modifizierten Steuerparameters eine Versorgung des elektrisch einstellbaren Ventils mit elektrischem Strom eine Gasdurchflussmenge beeinflussbar sein. Eine solche Ausführungsform der vorliegenden Erfindung bietet den Vorteil, dass die Erfindung nicht nur in elektrischen Kochfeldern sondern auch bei gasbetriebenen Kochfeldern eingesetzt werden kann, wodurch der vorliegende Ansatz auch bei weiteren Kochfeldtypen wie speziell einem potentiell sehr gefährlichen Gas-Kochfeld, das beim Betrieb eine offene Flamme aufweist, eingesetzt werden kann. Eine Betriebssicherheit derartiger Kochfeldtypen kann durch den vorgeschlagenen Ansatz verbessert werden, so dass eventuell ein Austausch eines solchen gefährlichen Gas-Kochfelds bei einem Bediener mit nicht mehr so hohem Überwachungsvermögen vermieden werden kann.In another hob in which the at least one heating element is formed by a gas-driven heating element with an electrically adjustable gas supply valve, according to another embodiment of the present invention by means of the modified control parameter, a supply of the electrically adjustable valve with electric current, a gas flow rate can be influenced. Such an embodiment of the present invention offers the advantage that the invention can be used not only in electric cooktops but also in gas-fired cooktops, whereby the present approach also in other hob types such as a potentially very dangerous gas cooktop, which is an open in operation Flame has, can be used. Operational safety of such hob types can be improved by the proposed approach, so that eventually an exchange of such a dangerous gas hob can be avoided by an operator with no longer so high monitoring capacity.
Gemäß einer weiteren Ausführungsform der vorliegenden Erfindung kann das Kochfeld ferner einen Sensor zur direkten oder indirekten Bestimmung einer aktuellen Wärmeabgabe durch das Heizelement aufweisen, der mit dem Heizelement und der Schutzvorrichtung zu einer Regelschleife zur Einstellung einer Energiezufuhr an das Heizelement verschaltet ist. Eine derartige Ausführungsform der vorliegenden Erfindung bietet den Vorteil, dass durch den Sensor eine kontinuierliche Überwachung des Betriebszustandes des Kochfeldes möglich ist, so dass durch die Regelschleife sichergestellt werden kann, dass sich das Heizelement nur bis zur Maximaltemperatur aufheizt oder höchstens mit einem definierten maximalen Temperaturgradienten aufgeheizt wird.According to another embodiment of the present invention, the cooktop may further comprise a sensor for direct or indirect determination of a current heat output by the heating element, which is connected to the heating element and the protection device to a control loop for adjusting a power supply to the heating element. Such an embodiment of the present invention has the advantage that continuous monitoring of the operating state of the hob is possible by the sensor, so that it can be ensured by the control loop that the heating element heats up only to the maximum temperature or heated at most with a defined maximum temperature gradient becomes.

Die Heizelemente 207 in
Die Heizelemente 207 sind mit einer Schutzvorrichtung 210 entsprechend einem Ausführungsbeispiel der Erfindung verbunden, wobei der Übersichtlichkeit halber nur das vordere Heizelement 207 mit der Schutzvorrichtung verbunden ist. Die Schutzvorrichtung 210 ist mit einem der Bedienelemente 155 verbunden, so dass ein Benutzer des Kochfeldes 110 mittels des Bedienelementes 155 für das Heizelement 207 der vorderen Kochzone 115 einen Steuerparameter 215 an die Schutzvorrichtung 210 Übermittelen kann, der einer bestimmten Energiezufuhr an das Heizelement 207 der vorderen Kochzone 115 entspricht. Weiterhin ist eine Eingabeschnittstelle vorgesehen, die beispielsweise an einer von dem Bedienelement 155 abgewandten Seite 217 (also einer Rückseite des Haushaltsgerätes 100) angeordnet ist. Diese Eingabeschnittstelle ist beispielsweise als Steckanschluss 220a ausgebildet, mittels dessen ein entfernbares Datenkabel 225 mit einem Stecker mit der Schutzvorrichtung 210 elektrisch verbunden werden kann. Über dieses Datenkabel 225 kann eine autorisierte Person, wie beispielsweise ein Betreuer des üblichen Bedieners des Kochfeldes 100 oder ein Mitarbeiter des technischen Kundendienstes für das Kochfeld 110 einen Modifikationsparameter 227 an die Schutzvorrichtung übertragen. Ferner kann dabei der Modifikationsparameter in der Eingabeschnittstelle 220a oder der Schutzvorrichtung 210 gespeichert werden, so dass er auch nach einem Entfernen des Datenkabels 225 noch für den Betrieb des Kochfeldes zur Verfügung steht. Eine alternative Ausführungsform der Eingabeschnittstelle kann eine manuelle Eingabeschnittstelle 220b sein, beispielsweise in der Form eines Drehrades oder Drehschalters, oder es kann ein Eingabeschnittstelle in der Form eines Funkempfängers 220c vorgesehen sein, der ausgebildet ist, um Funksignale von einem in der
Aus dem Steuerparameter 215 und dem Modifikationsparameter 227 wird in der Schutzvorrichtung 210 entsprechend der nachfolgend noch nähere beschriebenen Vorgehensweise ein modifizierter Steuerparameter 230 ermittelt und an das Heizelement 207 der vorderen Kochzone 115 ausgegeben. Dabei wird der modifizierte Steuerparameter 230 so bestimmt, dass das Heizelement 207 der vorderen Kochzone 115 eine definierte Maximaltemperatur nicht überschreitet oder das Heizelement 207 höchstens mit einem definierten zeitlichen Temperaturgradienten aufgeheizt wird. Hierbei ist es möglich, dass durch die Wahl des Modifikationsparameters 227 eine für den Benutzer des Kochfelds 110 individuelle Einstellung dieser definierten Maximaltemperatur des Heizelementes 207 der vorderen Kochzone oder eine individuelle Einstellung dieses definierten zeitlichen Temperaturgradienten des Heizelementes 207 der vorderen Kochzone 115 eingestellt werden kann, die seiner Fähigkeit zur Überwachung des Betriebs dieser Kochzone des Kochfeldes 110 entspricht.From the
Für mehrere, insbesondere für jede der Kochzonen kann eine solche Schutzvorrichtung vorgesehen sein, wobei die in
Um eine möglichst genaue aktuelle Bestimmung oder Regelung der Energiezufuhr an das Heizelement 207 sicherzustellen, ist ferner ein Sensor 240 vorgesehen, der über eine direkte oder indirekte Messung eine Temperatur einer Oberfläche der Glaskeramikplatte 203 oder des Kochgeschirrs auf der Glaskeramikplatte 203 über der vorderen Kochzone bestimmt. Ein Messwert dieses Sensors 240 wird an die Schutzvorrichtung 210 übertragen, die diesen Messwert für eine Regelung der Energiezufuhr an das Heizelement verwendet, um den modifizierten Steuerparameter zu bestimmen.In order to ensure the most accurate current determination or regulation of the power supply to the
Ein Ausführungsbeispiel der Funktionsweise einer Schutzvorrichtung 210 gemäß der Darstellung aus
Das Bedienelement 155 ist mit der Schutzvorrichtung 210 verbunden. Bei dem Bedienelement 155 kann es sich, wie zuvor beschrieben, um ein herkömmliches Bedienelement eines handelsüblichen Kochfeldes handeln, wie beispielsweise ein Drehknopf zur Einstellung der Temperatur einer Kochzone. Die genaue Ausgestaltung des Bedienelements 155 ist für die Zwecke der vorliegenden Erfindung von nachrangiger Bedeutung, solange ein Hauptbenutzer des Kochfeldes mittels des Bedienelements 155 eine Sollenergiezufuhr an das zugehörige Heizelement in Form eines Steuerparameters 215 für die Kochzone auswählen kann. Dieser Steuerparameter 215 wird an die Schutzvorrichtung 210 übertragen.The
Die Eingabeschnittstelle 220 ist mit der Speichereinrichtung 310 verbunden. Die Eingabeschnittstelle 220 umfasst eine manuelle Schnittstelle, eine elektronische Schnittstelle oder eine Kombination aus einer manuellen Schnittstelle und einer elektronischen Schnittstelle. Die Eingabeschnittstelle 220 kann ähnlich dem Bedienelement 155 gestaltet sein, beispielsweise als Drehknopf, Eingabetaste oder auch als Steckeranschluss für ein elektronisches Gerät, wobei die Eingabeschnittstelle 220 von dem Bedienelement 155 getrennt angeordnet ist. Wiederum ist die genaue Ausgestaltung der Eingabeschnittstelle 220 für die Zwecke der vorliegenden Erfindung nicht von zentraler Bedeutung, solange ein Benutzer des Kochfeldes, insbesondere eine von dem Hauptbenutzer unterschiedliche Person, mittels der Eingabeschnittstelle 220 zumindest einen Modifikationsparameter 227 auswählen oder festlegen kann. Dieser zumindest eine Modifikationsparameter 227 wird in die Speichereinrichtung 310 übertragen.The
Die Eingabeschnittstelle 220 ist zum einen mit der Speichereinrichtung 310 und zum anderen mit der Schutzvorrichtung 210 verbunden. Aus der Speichereinrichtung 310 ist der Modifikationsparameter 227 durch die Schutzvorrichtung 210 abrufbar. Die Speichereinrichtung 310 kann irgendeine auf dem Gebiet bekannte, geeignete Speichereinrichtung wie beispielsweise ein FPGA, ein EEPROM, ein Flash-Memory oder anderer elektronisch programmierbarer Baustein sein. In die Speichereinrichtung 310 kann beispielsweise auch durch eine elektronische Eingabe ein Verlauf von unterschiedlichen Modifikationsparametern hinterlegt werden, der eine Energiezufuhr an das Heizelement für unterschiedliche Steuerparameter abbildet. Dabei kann in der Schutzvorrichtung 210 eine Modifikation des Steuerparameters derart erfolgen, dass durch den Steuerparameter 215 eine gewünschte Solltemperatur T eingegeben wird, die einem Arbeitspunkt auf dem in dem Diagramm 332 durchgezogenen Verlauf entspricht, so dass eine zugehörige Energiezufuhr H an das Heizelement 207 hierfür erforderlich wäre. Da nun der Benutzer des Kochfeldes nur eine eingeschränkte Wahrnehmungsfähigkeit hat, kann diese Energiezufuhr bereits dazu führen, dass von dem Kochfeld erhebliche Gefahren ausgehen. Um diese Gefahren zu vermieden wird in der Schutzeinheit 210 der Steuerparameter 215 derart modifiziert, dass die Temperatur T des Heizelementes nur mehr eine in
Mittels dieses modifizierten Steuerparameters 230 wird somit eine Energiezufuhr durch das Heizelement 207 derart gesteuert oder geregelt, so dass das Heizelement 207 eine Heizleistung, eine Temperatur oder einen Temperaturanstieg entsprechend dem modifizierten Steuerparameter 230 an ein Kochgeschirr wie einen Topf oder eine Pfanne abgibt, das sich auf dem Kochfeld über dem Heizelement 207 befindet.Thus, by means of this modified
