Description
Die Erfindung betrifft ein Verfahren zum Betreiben eines Garofens sowie einen Garofen.The invention relates to a method for operating a cooking oven and a cooking oven.
Bei einem bekannten Garofen gemäß
Der Erfindung liegt die Aufgabe zugrunde, bei geringem Energieverbrauch und niedrigem Geräuschpegel das Garergebnis zu verbessern.The invention has for its object to improve the cooking result with low energy consumption and low noise level.
Erfindungsgemäß wird diese Aufgabe durch Merkmale der Ansprüche 1 und 4 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.According to the invention this object is achieved by features of
Bei dem erfindungsgemäßen Verfahren zum Betreiben eines Garofens wird die Intensität seiner Belüftung in Abhängigkeit von vorbestimmten Prozeßdaten eines ausgewählten Rezeptes gesteuert.In the method according to the invention for operating a cooking oven, the intensity of its aeration is controlled in dependence on predetermined process data of a selected recipe.
Hierbei kann die Intensität der Belüftung aus einem vorbestimmten Temperatur-Zeit-Verlauf des Rezeptes und/oder einem vorbestimmten Feuchte-Zeit-Verlauf des Rezeptes abgeleitet werden. Es ist aber auch möglich, dem Rezept einen vorbestimmten Belüftungs-Zeit-Verlauf zuzuordnen. Dabei läßt sich die Intensität der Belüftung über den Öffnungsgrad einer in einem Wrasenabzugskanal angeordneten Klappe oder Blende und/oder über die Drehzahl eines Wrasenabsauggebläses steuern.In this case, the intensity of the ventilation can be derived from a predetermined temperature-time profile of the recipe and / or a predetermined moisture-time profile of the recipe. But it is also possible to assign the recipe a predetermined ventilation time course. In this case, the intensity of the ventilation can be controlled via the opening degree of a valve or orifice arranged in a vapor withdrawal channel and / or via the rotational speed of a vapor suction blower.
Der erfindungsgemäße Garofen, insbesondere zur Durchführung des angegebenen Verfahrens, besitzt
- Speichermittel zur Speicherung vorbestimmter Prozeßdaten von Rezepten,
- Auswahlmittel zur Auswahl von Rezepten und
- Steuermittel, die auf die Auswahlmittel und die Speichermittel ansprechen, um die Intensität der Belüftung in Abhängigkeit von den gespeicherten Prozeßdaten des ausgewählten Rezeptes zu steuern.
- Storage means for storing predetermined process data of recipes,
- Selection means for the selection of recipes and
- Control means, responsive to the selection means and the storage means, for controlling the intensity of the aeration in response to the stored process data of the selected recipe.
Hierbei sind die vorbestimmten Prozeßdaten vorzugsweise ein Temperatur-Zeit-Verlauf und/oder ein Feuchte-Zeit-Verlauf und/oder ein Belüftungs-Zeit-Verlauf. Die Intensität der Belüftung ist insbeondere durch den Öffnungsgrad einer im Wrasenabsaugkanal befindlichen Klappe oder Blende und/oder durch die Drehzahl eines im Wrasenabsaugkanal befindlichen Gebläses steuerbar.In this case, the predetermined process data are preferably a temperature-time curve and / or a moisture-time curve and / or a ventilation-time curve. The intensity of the ventilation is in particular by the degree of opening of a Wrasenabsaugkanal located in the flap or aperture and / or controllable by the speed of a fan located in Wrasenabsaugkanal blower.

Der ansonsten nicht dargestellte Garofen weist eine Steuerung 2 auf, die eingangsseitig u. a. mit Auswahlmitteln 4 und Speichern 6 und 8 zusammenwirkt und ausgangsseitig u. a. auf wenigstens ein Heizelement 10, wenigstens ein Gebläse 12 und wenigstens eine Öffnungsklappe bzw. -blende 14 arbeitet.The cooking oven, not otherwise shown, has a
Die Auswahlmittel 2 dienen der Auswahl eines von mehreren Rezepten.The selection means 2 are used to select one of several recipes.
Der Speicher 6 enthält je Rezept wenigstens einen vorbestimmten Prozeßverlauf wie einen Temperatur-Zeit-Verlauf und gegebenenfalls einen Feuchte-Zeit-Verlauf und/oder einen Belüftungsintensitäts-Zeit-Verlauf. Im Speicher 8 sind Ableitungsregeln abgelegt, um aus einem Prozeßverlauf, beispielsweise einem Temperatur-Zeit-Verlauf und/oder einem Feuchte-Zeit-Verlauf, einen Belüftungsintensitäts-Zeit-Verlauf abzuleiten.The memory 6 contains per recipe at least one predetermined process profile such as a temperature-time course and optionally a moisture-time course and / or a ventilation intensity-time course. In the
Mit dem wenigstens einen Heizelement 10 ist die Temperatur des Garofens einstellbar. Das Gebläse 12 dient der Wrasenabsaugung. Es kann in einem Wrasenabsaugkanal angeordnet sein. Seine Drehzahl beeinflußt die Absaugmenge. Eine alternative oder zusätzliche Möglichkeit der Beeinflussung der Absaugmenge bietet die Öffnungsklappe bzw. -blende 14, welche in einem Wrasenabsaugkanal angeordnet ist, um dessen Querschnitt zu beeinflussen.With the at least one
Wählt ein Nutzer an den Auswahlmitteln 4 als Rezept einen Kuchen, liest die Steuerung aus dem Speicher 6 neben einem nichtdargestellten Temperatur-Zeit-Verlauf beispielsweise einen in
Im Speicher 6 können jedoch auch von vornherein rezeptbezogene Belüftungsintensitäts-Zeit-Verläufe abgelegt sein, so daß deren Ableitung nicht erforderlich ist und der Speicher 8 entfallen kann.In the memory 6, however, recipe-related aeration intensity-time profiles can also be stored from the outset, so that their derivation is not required and the
Auf einen vorbestimmten Feuchte-Zeit-Verlauf bezogen, können die Ableitregeln darin bestehen, den Feuchtewerten über einen Faktor Belüftungsintensitäts-Werte zuzuordnen und/oder den Belüftungsintensitäts-Verlauf gegenüber dem Feuchte-Verlauf zeitlich zu verschieben. Statt der Umsetzung der gesamten Feuchtekurve in eine proportionale Belüftungsintensitätskurve ist es auch möglich, der Feuchtekurve Schwellwerte zuzuordnen, deren Überschreitung einer ersten konstanten Belüftungsintensität und deren Unterschreiten einer zweiten konstanten Belüftungsintensität entspricht. So könnte (beispielsweise gemäß
Wählt der Nutzer an den Auswahlmitteln statt eines Kuchens einen Schweinebraten aus, liest die Steuerung 2 aus dem Speicher 6 u. a. den in
In beiden Fällen ist gesichert, daß das Gargut unter optimalem Klima gart und der Energieverbrauch und der Geräuschpegel das notwenige Maß nicht übersteigen.In both cases, it is ensured that the food to cook under optimal climate and the energy consumption and noise level does not exceed the necessary level.
Der gewünschte Feuchte-Zeit-Verlauf läßt sich annähern, indem man den Feuchtigkeitsanfall beim Garen mittels Feuchtesensor meßtechnisch erfaßt und entsprechend nachregelt und/oder gezielt Feuchtigkeit zuführt. Insoweit reicht die Anwendungsbreite von klassischen Garöfen bis zu Multifunktionsgeräten, die eine stufenlose Regelung von Heißluft bis zur Dampffunktion ermöglichen.The desired moisture-time curve can be approximated by measuring the moisture accumulation during cooking by means of humidity sensor and adjusted accordingly and / or specifically supplies moisture. In that regard, the breadth of application extends from classic cooking ovens to multifunctional devices that allow continuous control of hot air to the steam function.
