Erwärmungsprozesse auf Kochmulden können durch Auswertung
der Temperatur des Gargutes automatisiert werden. Verschiedene Prinzipien sind dabei mit unterschiedlichen Sensortechniken
gekoppelt. Ein im Stand der Technik bekanntes Infrarot-Meßsystem ist dabei als besonders zweckmäßig in Erscheinung

Zusatzgerät mittels Infrarotsender und Infrarotempfänger mit einer Kochmulden-Elektronik Kochdaten austauscht und daß als Folge davon eine Strahlungsheizung mit kochprozeßnahen Leistungszuschaltungen durch die Kochmulden-Elektronik steuerbar ist.Additional device exchanges cooking data with a hob electronics by means of an infrared transmitter and infrared receiver and that as a result a radiant heater with power switches close to the cooking process can be controlled by the hob electronics.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen entnehmbar.Further advantageous embodiments of the invention can be found in the subclaims.
Ein Ausführungsbeispiel nach der Erfindung ist im folgenden anhand der Zeichnung näher beschrieben. Die Figur zeigt das Prinzip der Erfindung.An embodiment of the invention is described in more detail below with reference to the drawing. The figure shows the principle of the invention.
Gemäß der einzigen Figur ist eine sensorgesteuerte Glaskeramik-Kochstelleneinheit dargestellt, die aus einem Topf 1, einem Zusatzgerät 4, einer Glaskeramik-Kochfläche 11, einer Muldenelektronik 13 und einer Strahlungsheizquelle 16 besteht. Der mit Kochgut auf der Glaskeramik-Kochfläche 11 plazierte Topf 1 korrespondiert mit dem Zusatzgerät über einen Infrarotsensor. Der Infrarotsensor erzeugt am Topf einen Infrarot-Meßfleck 2a, der vom im Zusatzgerät 4 befindlichen Infrarotsensor 5 herrührt. Der Infrarotsensor 5 funktioniert über ein Austrittsfenster für Infrarotstrahlen 2b, das an einer Austrittsstelle des Zusatzgerätes 4 angeordnet ist. Eine für das Zusatzgerät 4 notwendige Elektronik 6 befindet sich in Korrespondenz mit Anzeigeelementen 7 und Bedienelementen 8 des Zusatzgerätes und einer Infrarotsender- und -Empfängereinheit 9 im Zusatzgerät. Die Infrarotsender- und -Empfängereinheit 9 des Zusatzgerätes besitzt ein Fenster für Infrarotstrahlung, das über einer gleichen Einheit 12 in der Mulde durch die Glaskeramik-Kochfläche 11 getrennt direkt korrespondiert. Die Infrarotsender- und -Empfangsanlage 12 der Mulde verkehrt bidirektional mit der Kochmuldenelek-According to the single figure, a sensor-controlled glass ceramic cooking unit is shown, which consists of a pot 1, an additional device 4, a glass ceramic cooking surface 11, a recessed electronics unit 13 and a radiant heat source 16. The pot 1, which is placed with food on the glass ceramic cooking surface 11, corresponds to the additional device via an infrared sensor. The infrared sensor generates an infrared measuring spot 2a on the pot, which comes from the infrared sensor 5 located in the additional device 4. The infrared sensor 5 functions via an exit window for infrared rays 2b, which is arranged at an exit point of the additional device 4. Electronics 6 required for the additional device 4 are located in correspondence with display elements 7 and control elements 8 of the additional device and an infrared transmitter and receiver unit 9 in the additional device. The infrared transmitter and receiver unit 9 of the additional device has a window for infrared radiation, which corresponds directly to an identical unit 12 in the hob separated by the glass ceramic cooking surface 11. The infrared transmitter and receiver system 12 of the hob operates bidirectionally with the hob electronics.

tronik 13, die von einem Netzspannungs-Zuführungsmodul 14 gespeist wird. Über ein Leitungsbündel 15 wird die Strahlungsheizung der Kochstelle 16 mit Kochstellen-Leistungszuschaltungen durch die Kochmuldenelektronik 13 beaufschlagt.electronics 13, which is fed by a mains voltage supply module 14. The radiant heating of the cooking area 16 is supplied with cooking area power switches by the hob electronics 13 via a cable bundle 15.
Die vom Infrarotsensor 5 über die Temperatur des Kochgeschirres bereitgestellten Signale werden entsprechend der gewählten Erwärmungsautomatik ausgewertet. Diese Auswertung findet im Zusatzgerät 4 statt, das durch eine dafür geeignete Elektronik 6 entscheidet, ob die Heizung der Kochstelle ein- oder ausgeschaltet werden muß. Die Schaltsignale gibt das Zusatzgerät durch die Bedienelemente 8 an die Elektronik 13 der Mulde weiter. Dabei ist zu beachten, daß die Unterseite des Zusatzgerätes 4 so aufgebaut ist, daß sie keine Infrarotimpulse an die Muldenelektronik 13 reflektieren kann. Das Zusatzgerät 4 ist in der Lage, sich durch Auswertung der Infrarot-Sendeimpulse auf die Muldenelektronik 13 zu sychronisieren und geeignete eigene Infrarotimpulse an die Muldenelektronik 13 abzusenden, so daß die Infrarotimpulse des Zusatzgerätes 4 von der Muldenelektronik 13 als reflektierte Infrarotimpulse erkannt werden. Die detaillierte technische Ausführung hängt auch davon ab, welche Komplexität der Signalauswertung die jeweilige Muldenelektronik besitzt. Das Zusatzgerät 4, das mit mechanischen bzw. elektrostatischen Hilfen genau auf der Glaskeramik-Kochfläche positioniert werden kann, ermöglicht es, daß die Kochmulde weder mechanisch noch elektrisch an das Sensorsystem angepaßt werden müßte.The signals provided by the infrared sensor 5 regarding the temperature of the cookware are evaluated according to the selected automatic heating system. This evaluation takes place in the additional device 4, which uses suitable electronics 6 to decide whether the heating of the cooking area must be switched on or off. The additional device passes the switching signals on to the electronics 13 of the hob via the control elements 8. It should be noted that the underside of the additional device 4 is designed in such a way that it cannot reflect infrared pulses to the hob electronics 13. The additional device 4 is able to synchronize itself with the hob electronics 13 by evaluating the infrared transmission pulses and to send its own suitable infrared pulses to the hob electronics 13, so that the infrared pulses of the additional device 4 are recognized by the hob electronics 13 as reflected infrared pulses. The detailed technical design also depends on the complexity of the signal evaluation of the respective hob electronics. The additional device 4, which can be positioned precisely on the glass ceramic cooking surface using mechanical or electrostatic aids, means that the hob does not have to be adapted to the sensor system either mechanically or electrically.
Im übrigen kann der Prozessor der Kochmulde erkennen, daß diese gerade nicht durch einen Menschen, sondern durch das Zusatzgerät bedient wird. Um dies zu garantieren, sind besondere Austauschsignale zwischen Zusatzgerät 4 und Kochmul-Furthermore, the processor of the hob can recognize that it is not being operated by a person, but by the additional device. To guarantee this, special exchange signals are required between the additional device 4 and the hob.

de vereinbart. Für diese Zwecke können zudem unterstützende Software-Optionen zur Unterstützung des Zusatzgerätes 4 seitens der Muldenelektronik vorhanden sein. Der Prozessor der Muldenelektronik 13 kann bei Bedarf auch Signale an das Zusatzgerät 4 senden. Bei vorhandenen Infrarotreflex-Lichtschranken geschieht das durch geeignete Variation der Sendeimpulse; bei kapazitiven Berührungssensoren kann beispielsweise die Frequenz des Schwingkreises variiert werden. In vorteilhafter Weise kann also ein Zusatzgerät 4 der vorgenannten Erfindungsproblematik bereits vorhandene Mulden sensormeßtechnisch aufwerten. Der Muldenbediener kann von Zeit zu Zeit entscheiden, ob er ein programmiertes, sensorgesteuertes Garen wünscht oder traditionell kochen möchte.de agreed. For these purposes, supporting software options can also be available to support the additional device 4 on the part of the trough electronics. The processor of the trough electronics 13 can also send signals to the additional device 4 if required. If infrared reflex light barriers are present, this is done by suitably varying the transmission pulses; with capacitive touch sensors, for example, the frequency of the oscillating circuit can be varied. An additional device 4 of the aforementioned invention problem can therefore advantageously upgrade existing troughs in terms of sensor measurement technology. The trough operator can decide from time to time whether he wants programmed, sensor-controlled cooking or whether he wants to cook traditionally.
