Description

Die Erfindung geht aus von einem Gargerät nach dem Oberbegriff des Anspruchs 1.The invention relates to a cooking appliance according to the preamble of claim 1.

Aus der EP 0545 012 B1 ist ein gattungsbildendes Gargerät mit einem Lüfter bekannt, der als Kühllüfter und als Wrasenlüfter dient. Das Gargerät besitzt eine Steuereinheit mit einer Schaltungsanordnung zur Steuerung des Lüfters. Der Lüfter bzw. ein Lüftermotor ist einerseits mit einem Nulleiter und andererseits mit einem durch einen Schalter überbrückbaren Widerstand beschaltet. Der Widerstand ist abhängig von der Stellung eines Betriebsarten-Umschalters direkt mit einer Wechselspannungsquelle oder in Reihenschaltung mit einem Temperaturfühler verbunden. Der Temperaturfühler, der im Betrieb separat elektrisch beheizt wird, schließt infolge der Beheizung nach etwa 3 Minuten einen Kontakt und verbindet dadurch bei entsprechender Stellung des Betriebsarten-Umschalters den Lüftermotor über den Widerstand und über den Kontakt mit der Wechselspannungsquelle. Durch die Schaltungsanordnung wird eine von der mit dem Betriebsarten-Umschalter gewählten Betriebsart abhängige Steuerung erreicht.From the EP 0545 012 B1 is a generic cooking appliance with a fan known, which serves as a cooling fan and as a steam fan. The cooking appliance has a control unit with a circuit arrangement for controlling the fan. The fan or a fan motor is connected on the one hand with a neutral conductor and on the other hand with a bridgeable by a switch resistor. The resistor is connected directly to an AC voltage source or in series with a temperature sensor depending on the position of a mode switch. The temperature sensor, which is electrically heated separately during operation, closes a contact as a result of the heating after about 3 minutes and thereby connects the fan motor via the resistor and via the contact with the AC voltage source with the appropriate position of the operating mode changeover switch. The circuitry achieves control dependent on the mode selected with the mode selector switch.

Die Aufgabe der Erfindung besteht darin, ein gattungsgemäßes Gargerät mit einer besonders flexiblen und exakten Steuerung des Wrasenlüfters bei gleichzeitig geringem konstruktiven Aufwand bereitzustellen. Die Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst, während vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung den Unteransprüchen entnommen werden können.The object of the invention is to provide a generic cooking appliance with a particularly flexible and precise control of the steam fan with low design effort. The object is achieved by the features of claim 1, while advantageous embodiments and modifications of the invention can be taken from the dependent claims.

Es kann eine besonders flexible, sichere und kostengünstige Steuerung mit geringem konstruktiven Aufwand erreicht werden. Es kann bei zahlreichen Garbetriebsarten und über verschiedene Garbetriebsprogramme stets ein vorteilhaft abgestimmter Betrieb des Wrasenlüfters erreicht werden, indem die Kenngrösse Einschaltzeit, d.h. eine Zeitspanne zwischen dem Beginn eines Garbetriebs und dem Start des Wrasenlüfters, auf mehrere unterschiedliche Kenngrößenwerte eingestellt werden kann. Es können für verschiedene Garbetriebsprogramme abgestimmte Wrasenlüfterprogramme erreicht werden, Energie kann eingespart und Störungen durch einen unnötigen Wrasenlüfterbetrieb können vermieden werden.It can be a particularly flexible, safe and cost-effective control can be achieved with little design effort. It can be achieved in many Garbetriebsarten and various Garbetriebsprogramme always an advantageous tuned operation of the steam blower by the characteristic size of turn-on, i. a period of time between the start of a cooking operation and the start of the steam blower, can be set to several different characteristic values. It can be tuned for various cooking programs Wrasenlüfterprogramme be achieved, energy can be saved and disturbances by an unnecessary Wrasenlüfterbetrieb can be avoided.

Unter Garbetriebsarten sollen Betriebsarten mit verschiedenen Temperaturen verstanden werden und Betriebsarten, die für verschiedene Gargefäße und/oder für verschiedene Gargüter ausgelegt sind, sowie insbesondere Betriebsarten mit unterschiedlichem Einsatz von Heizelementen, wie beispielsweise von einem Heizelement für eine Oberhitze, von einem Heizelement für eine Unterhitze, von einem Grillheizelement und/oder von einem Mikrowellenheizelement usw.Cooking modes are to be understood as operating modes with different temperatures and operating modes designed for different cooking vessels and / or for different food items, and in particular modes with different use of heating elements, such as a heating element for a top heat, from a heating element for a bottom heat, from a grill heater and / or from a microwave heating element, etc.

Ferner können bei der erfindungsgemäßen Lösung vorteilhaft bereits vorhandene Bauteile genutzt und zusätzliche Bauteile, wie insbesondere zusätzliche Sensoren usw., vermieden werden. Die Steuereinheit kann vorteilhaft zumindest teilweise einstückig mit einer Steuereinheit ausgeführt sein, über die die Heizeinheit steuerbar ist, und/oder die Speichereinheit kann vorteilhaft zumindest teilweise einstückig mit einer Speichereinheit ausgeführt sein, in der zumindest ein Garbetriebswert abgespeichert ist. Zusätzlicher Bauraum, Montageaufwand sowie zusätzliche Kosten können vermieden werden.Furthermore, in the solution according to the invention, existing components can advantageously be used and additional components, such as, in particular, additional sensors, etc., can be avoided. The control unit can advantageously be designed at least partially in one piece with a control unit, via which the heating unit can be controlled, and / or the storage unit can advantageously be embodied at least partially in one piece with a storage unit in which at least one cooking duty value is stored. Additional space, installation costs and additional costs can be avoided.

Die Speichereinheit kann von verschiedenen, dem Fachmann als sinnvoll erscheinenden nichtflüchtigen Speichern gebildet sein. Besonders vorteilhaft werden jedoch sogenannte EPROMs (Erasable Programmable Read Only Memory) und insbesondere EE-PROMs (Electric Erasable Programmable Read Only Memory) eingesetzt, die gelöscht und wieder neu programmiert werden können. Die Speichereinheit kann dadurch beim Hersteller besonders flexibel auf bestimmte Randbedingungen programmiert werden.The memory unit can be formed by various nonvolatile memories that appear appropriate to the person skilled in the art. However, so-called EPROMs (Erasable Programmable Read Only Memory) and especially EE-PROMs (Electric Erasable Programmable Read Only Memory) are used particularly advantageously, which can be erased and reprogrammed again. The storage unit can thus be programmed very flexibly at the manufacturer for certain boundary conditions.

In einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, daß der Wrasenlüfter über die Steuereinheit abhängig von zumindest einem über einen Sensor erfaßten Wert steuerbar ist, beispielsweise abhängig von einem erfaßten Temperaturwert und insbesondere abhängig von einem erfaßten Luftfeuchtigkeitswert im Garraum usw. Es kann insbesondere eine zusätzliche Sicherungsfunktion aufgebaut werden. Ferner kann vorteilhaft ein lernendes System erreicht werden, indem abhängig von dem über den Sensor erfaßten Wert der gespeicherte Kenngrößenwert veränderbar ist. Es kann eine automatische Anpassung des Gargeräts an vorliegende und sich verändernde Randbedingungen erreicht werden, wie beispielsweise an eine vorliegende Umgebungstemperatur, Luftfeuchtigkeit usw., und Alterserscheinungen können ausgeglichen werden.In a further embodiment of the invention, it is proposed that the steam fan is controllable via the control unit depending on at least one detected value via a sensor, for example, depending on a detected temperature value and in particular dependent on a detected humidity value in the cooking chamber, etc. It can in particular an additional backup function being constructed. Furthermore, a learning system can advantageously be achieved in that the stored characteristic value can be changed depending on the value detected via the sensor. It can be achieved an automatic adjustment of the cooking appliance to existing and changing boundary conditions, such as a present ambient temperature, humidity, etc., and aging phenomena can be compensated.

Ist der Wrasenlüfter einstückig mit einem Kühllüfter ausgeführt, kann ein zusätzlicher Lüfter für die Kühlung temperaturempfindlicher Bauteile vermieden und es kann vorteilhaft eine garbetriebsabhängige Kühlung erreicht werden. Der oder die abgespeicherten Kenngrößenwerte können zudem auf die je Garbetriebsart vorteilhafte Kühlung abgestimmt werden.If the Wrasenlüfter designed in one piece with a cooling fan, an additional fan for the cooling of temperature-sensitive components can be avoided and it can be advantageously achieved a garbetriebsabhängige cooling. The one or more stored characteristic values can also be tuned to the cooling advantageous for each cooking mode.

Fig. 1 zeigt einen schematisch dargestellten Haushaltsbackofen mit einem Backofengehäuse, in dem ein Garraum 11 angeordnet ist. Der Garraum 11 ist mit einer schwenkbar gelagerten Tür 17 verschließbar und mit einer Heizeinheit 10 beheizbar, die ein Heizelement 25 im Deckenbereich für eine Oberhitze, ein Heizelement 26 im Bodenbereich für eine Unterhitze und eine Heizwendel 27 für einen Grillbetrieb im Deckenbereich aufweist. Fig. 1 shows a schematically illustrated domestic oven with an oven housing, in which a cooking chamber 11 is arranged. The cooking chamber 11 is closable with a pivotally mounted door 17 and heated with a heating unit 10, which has a heating element 25 in the ceiling area for a top heat, a heating element 26 in the bottom area for a bottom heat and a heating coil 27 for a grill operation in the ceiling area.

Über einen Lüfter 36 im rückseitigen Bereich kann eine Luftströmung für einen Umluftbetrieb erzeugt werden.A fan 36 in the rear area, an air flow for a recirculation mode can be generated.

Ferner besitzt der Haushaltsbackofen eine Bedieneinheit 18 mit sechs drehbaren Bedienelementen 19, 20, 21, 22, 23, 24. Über die in der Darstellung drei ersten drehbaren Bedienelemente 19, 20, 21 von links können Temperaturen von nicht näher dargestellten Heizelementen einer Kochmulde 16 eingestellt werden, die oberhalb des Haushaltsbackofens angeordnet ist. Über die drei weiteren drehbaren Bedienelemente 22, 23, 24 sind verschiedene Garbetriebsarten einstellbar, d.h. verschiedene Gartemperaturen im Garraum 11 mit unterschiedlichem Einsatz der Heizelemente 25, 26, 27.Furthermore, the household oven has a control unit 18 with six rotatable controls 19, 20, 21, 22, 23, 24. About the three first rotatable controls 19, 20, 21 from the left temperatures of not shown heating elements of a hob 16 set be located above the household oven. About the three other rotatable controls 22, 23, 24 different Garbetriebsarten are adjustable, i. various cooking temperatures in the cooking chamber 11 with different use of the heating elements 25, 26, 27th

Oberhalb des Garraums 11 ist in einem Zwischenraum 28 des Backofengehäuses ein Wrasenlüfter 12 mit einem elektrisch betriebenen Lüftermotor 29 und einem Lüfterrad 30 angeordnet (Fig. 2). Der Wrasenlüfter 12 dient zur Förderung von Wrasen 34 aus dem Garraum 11 nach außen. Der Wrasenlüfter 12 saugt hierzu den Wrasen 34 über eine Öffnung 35 im Deckenbereich des Garraums 11 an und fördert den Wrasen 34 über ein nicht näher dargestelltes Kanalsystem durch die Bedieneinheit 18 zu einer Ausblasöffnung unterhalb eines Türgriffs 33. Ferner ist der Wrasenlüfter 12 einstückig mit einem Kühllüfter ausgeführt und dient zur Kühlung der Bedieneinheit 18 mit ihren elektronischen Bauteilen. Der Wrasenlüfter 12 saugt hierzu Frischluft 32 über Seitenwände des Backofengehäuses an und fördert die Frischluft 32 gemeinsam mit dem Wrasen 34 über das Kanalsystem nach außen.Above the cooking chamber 11 is a Wrasenlüfter 12 with an electrically operated fan motor 29 and a fan 30 is disposed in a space 28 of the oven housing ( Fig. 2 ). The Wrasenlüfter 12 serves to promote vapors 34 from the cooking chamber 11 to the outside. The Wrasenlüfter 12 sucks the vapors 34 via an opening 35 in the ceiling region of the cooking chamber 11 and promotes the Wrasen 34 via a not-shown channel system through the control unit 18 to a blowout below a door handle 33. Furthermore, the steam fan 12 is integral with a cooling fan executed and used to cool the control unit 18 with its electronic components. The Wrasenlüfter 12 sucks this fresh air 32 via side walls of the oven housing and promotes the fresh air 32 together with the Wrasen 34 through the duct system to the outside.

Eine Einschaltzeit t des Wrasenlüfters 12, d.h. eine Zeitspanne vom Beginn eines über die Bedienelemente 22, 23, 24 gewählten Garbetriebs bis zum Start des Wrasenlüfters 12 ist über eine Steuereinheit 13 abhängig von der gewählten Garbetriebsart auf verschiedene Einschaltzeitwerte t1, t2, t3 steuerbar, wobei die Einschaltzeitwerte t1, t2, t3 in einer elektronischen Speichereinheit 14 abgespeichert sind, und zwar in einem EEPROM (Fig. 2 und 3). Bei einer Garbetriebsart mit der Heizwendel 27 bzw. beim Grillen wird der Wrasenlüfter 12 bei einem Einschaltzeitwert t1 von 3 Minuten, bei einer Garbetriebsart mit den Heizelementen 25, 26 bzw. beim Backen und Braten wird der Wrasenlüfter 12 bei einem Einschaltzeitwert t2 von 8 Minuten und bei einem Garbetriebsprogramm für einen Garbetrieb mit einem geschlossenen Gargefäß wird der Wrasenlüfter 12 bei einem Einschaltzeitwert t3 von 10 Minuten gestartet. Für die Garbetriebsarten sind im Diagramm in Fig. 3 Kennlinien K1, K2, K3 für den jeweils anfallenden Wrasen 34 über der Zeit t dargestellt. Der Wrasenlüfter 12 schaltet im wesentlichen bei den verschiedenen Garbetriebsarten stets bei derselben Wrasenmenge ein und wird stets mit derselben Drehzahl U betrieben.A switch-on time t of the steam blower 12, ie a period of time from the beginning of a cooking operation selected via the operating elements 22, 23, 24 to the start of the steam blower 12, is controlled by a control unit 13 to different switch-on time values t 1 , t 2 , t 3, depending on the selected cooking mode controllable, wherein the switch-on time values t 1 , t 2 , t 3 are stored in an electronic memory unit 14, in an EEPROM ( FIGS. 2 and 3 ). In a Garbetriebsart with the heating coil 27 or when grilling of the steam fan 12 is at a Einschaltzeitwert t 1 of 3 minutes, in a Garbetriebsart with the heating elements 25, 26 or when baking and frying the Wrasenlüfter 12 at a Einschaltzeitwert t 2 of 8 Minutes and a Garbetriebsprogramm for a cooking operation with a closed cooking vessel of the steam fan 12 is started at a switch-on time t 3 of 10 minutes. For the cooking modes are in the diagram in Fig. 3 Characteristics K 1 , K 2 , K 3 shown for each accumulating vapor 34 over time t. The Wrasenlüfter 12 switches substantially at the different Garbetriebsarten always at the same amount of vapor and is always operated at the same speed U.

Anstatt den Wrasenlüfter 12 nur mit einer Drehzahl U zu betreiben, könnte dieser auch mit einem einem Garbetriebsprogramm angepaßten Wrasenlüfterbetriebsprogramm mit unterschiedlichen Drehzahlen über der Zeit t betrieben werden, wie dies mit einer Kennlinie 31 in Fig. 3 angedeutet ist.Instead of only operating the steam fan 12 at a speed U, it could also be operated with a gland operating program adapted to a Wrasenlüfterbetriebsprogramm with different speeds over time t, as with a characteristic 31 in Fig. 3 is indicated.

Innerhalb des Garraums 11 ist ein mit der Steuereinheit 13 verbundener Luftfeuchtigkeitssensor 15 angeordnet. Übersteigt die Luftfeuchtigkeit f innerhalb des Garraums 11 einen vorgegebenen Feuchtigkeitsgrenzwert fXGrenz bevor der Wrasenlüfter 12 gestartet ist, wird dieser über die Steuereinheit 13 aktiviert. Neben einer zusätzlichen Sicherungsfunktion könnte mit dem Luftfeuchtigkeitssensor 15 ferner ein selbstlernendes System erreicht werden, und zwar indem beispielsweise in der Speichereinheit 14 abgespeicherte Drehzahlwerte des Wrasenlüfters 12 abhängig von erfaßten Luftfeuchtigkeitswerten fX korrigiert werden.Within the cooking chamber 11, a connected to the control unit 13 humidity sensor 15 is arranged. If the humidity exceeds f inside the cooking chamber 11 a predetermined humidity limit value f XGrenz before the extractor fan 12 is started, this is activated by the control unit. 13 In addition to an additional safety function, a self-learning system could also be achieved with the humidity sensor 15, namely by correcting, for example, speed values of the fan ventilator 12 stored in the memory unit 14 as a function of detected air humidity values f X.

Die Steuereinheit 13 ist einstückig mit einer Steuereinheit ausgeführt, über die die Heizeinheit 10 und eine Kochmulde 16 steuerbar sind, und die Speichereinheit 14 ist einstückig mit einer Speichereinheit ausführt, in der Garbetriebswerte, Garbetriebsprogramme und Kochbetriebswerte abgespeichert sind.
