Abstract

Die Erfindung betrifft ein Verfahren zur Steuerung eines Garvorgangs bei einem Gargerät mit einem Garraum, an bzw. in dem eine Heizquelle zur Beheizung des Garraums angeordnet ist, mit einem Sensor zur Erfassung einer Gaskonzentration in dem Garraum und einer elektrischen oder elektronischen Steuerung, die eine Auswerteschaltung und einen Speicher aufweist und mit dem Sensor in Signalübertragungsverbindung steht, wobei das Verfahren die folgenden Verfahrensschritte aufweist:
- Erstens, Ermittlung eines in dem Speicher abgespeicherten Garendewerts in Abhängigkeit eines manuell ausgewählten bzw. automatisch erkannten Garguts, mittels der Auswerteschaltung,
- zweitens, Verarbeitung des Ausgangssignals des Sensors in der Auswerteschaltung zur Erzeugung eines Garquotienten, wobei der Garquotient dem Verhältnis der ersten Ableitung des Ausgangssignals nach der Zeit (f') zu einem zeitlich vorher und nach dem Beginn des Garvorgangs ermittelten erstmaligen Extremwert der ersten Ableitung des Ausgangssignals nach der Zeit (f(extrem)) entspricht,
- drittens, Vergleich des Werts des Garquotienten mit dem Garendewert (G) in der Auswerteschaltung und
- viertens, Auslösen einer Gargerätfunktion erfolgt, sobald der Wert des Garquotienten nach dem Beginn des Garvorgangs den Garendewert (G) unterschreitet.The invention relates to a method for controlling a cooking process in a cooking appliance having a cooking chamber, on or in which a heating source for heating the cooking chamber is arranged, with a sensor for detecting a gas concentration in the cooking chamber and an electrical or electronic control, the evaluation circuit and a memory and in signal communication with the sensor, the method comprising the steps of:
- First, determination of a stored in the memory Garendewerts depending on a manually selected or automatically detected food, by means of the evaluation circuit,
secondly, processing the output signal of the sensor in the evaluation circuit to produce a cooking quotient, wherein the cooking quotient corresponds to the ratio of the first derivative of the output signal after the time (f ') to a first time derivative of the first derivative of the first derivative determined before and after the cooking process Output signal after time (f (extreme) ),
thirdly, comparison of the value of the cooking quotient with the cooking value (G) in the evaluation circuit and
- fourthly, a cooking appliance function is triggered as soon as the value of the cooking quotient falls below the cooking value (G) after the start of the cooking process.

Auf diese Weise ist ein Verfahren zur Steuerung eines Garvorgangs angegeben, bei dem die Steuerung auch für unterschiedliche Gargüter und für unterschiedliche Mengen und Verteilungen eines Garguts in dem Garraum auf einfache Weise realisiert ist und unabhängig von dem zu behandelnden Gargut gleichzeitig eine Restgarzeit mit einer hohen Genauigkeit und Reproduzierbarkeit ermittelt werden kann.

Figure imgaf001
In this way, a method for controlling a cooking process is specified, in which the control is realized for different food items and for different amounts and distributions of a food in the oven in a simple manner and regardless of the food to be treated at the same time a Restgarzeit with high accuracy and reproducibility can be determined.
