Description

Die Erfindung betrifft ein Verfahren zum Betrieb einer Dunstabzugshaube mit einer Bedieneinrichtung, einer Steuereinrichtung zur Ansteuerung eines Gebläsemotors sowie einer Auswerteeinrichtung in der Betriebszustände eines der Dunstabzugshaube zugeordneten Kochfeldes für die Ansteuerung des Gebläsemotors ausgewertet werden, wobei der Auswerteeinrichtung ein Kommunikationsmodul zugeordnet ist.The invention relates to a method for operating an extractor hood with an operating device, a control device for controlling a fan motor and an evaluation in the operating conditions of the hood associated hob for the control of the fan motor are evaluated, wherein the evaluation device is assigned a communication module.

Ein derartiges Verfahren zum Betrieb einer Dunstabzugshaube ist aus der WO2006/097575 A1 bekannt. Kochfeld und Dunstabzugshaube stehen miteinander über ein Modem in Verbindung. Der Betrieb der Dunstabzugshaube erfolgt in Abhängigkeit vom Betrieb des Kochfeldes und umgekehrt. So ist z.B. eine Kindersicherung für das Kochfeld dadurch erreicht, dass das Kochfeld nur bei eingeschalteter Dunstabzugshaube in Betrieb genommen werden kann. Für eine temperaturabhängige Einstellung der Gebläsedrehzahl der Dunstabzugshaube oder für die Nutzung von Sicherheitsabschaltungen ist dem Kochfeld zusätzlich ein Temperatursensor zugeordnet.Such a method for operating an extractor hood is from the WO2006 / 097575 A1 known. Hob and extractor hood communicate with each other via a modem. The operation of the cooker hood is dependent on the operation of the hob and vice versa. For example, a child safety device for the hob is achieved by the fact that the hob can only be put into operation when the hood is switched on. For a temperature-dependent adjustment of the fan speed of the extractor hood or for the use of safety shutdowns, the hob is additionally assigned a temperature sensor.

Weiter ist aus der DE 100 06 240 A1 eine Dunstabzugshaube mit einer Spracheingabeeinheit und mit einer Sprachverarbeitungseinheit bekannt, über die aus gesprochenen Eingabebefehlen Steuersignale für die Funktion des Kochfeldes und der Dunstabzugshaube erzeugt werden. Kochfeld und Dunstabzugshaube sind jeweils mit Sende- und Empfangseinrichtungen für eine Kommunikation über eine drahtlose Übertragungsstrecke Ü ausgebildet. Die Sende- und Empfangseinrichtung sowie die Sprachverarbeitungseinrichtung der Dunstabzugshaube sind mit einer Betriebsstatus-Erkennungseinheit verbunden, über die etwaige Störgeräusche von im Betrieb befindlichen Geräten erfasst werden. Erfolgt zum Beispiel eine Spracheingabe zur Ansteuerung des Kochfeldes bei laufender Dunstabzugshaube erfolgt eine Geräuschquellenkorrektur in der Sprachverarbeitungseinheit.Next is from the DE 100 06 240 A1 an extractor hood with a voice input unit and with a voice processing unit known, are generated from the spoken input commands control signals for the function of the hob and the hood. Hob and extractor hood are each formed with transmitting and receiving devices for communication via a wireless transmission link Ü. The transmitting and receiving device and the voice processing device of the hood are connected to an operating status detection unit, are detected on the noise of any operating devices. If, for example, a voice input is made to control the cooktop while the extractor hood is running, a noise source correction takes place in the speech processing unit.

Aus der DE 40 41 798 C2 ist es bekannt, dass der Betrieb der Dunstabzugshaube automatisch einsetzt, wenn der Benutzer z.B. mittels Zeitvorwahl sowie Einstellung eines Garprogramms an einem der Dunstabzugshaube zugeordneten Kochfeld einen automatischen Betrieb des Kochfeldes vorgegeben hat. Das Kochfeld ist mit einem Infrarotsender ausgebildet, welcher Signale an ein fotoelektrisches Empfangselement auf der Unterseite der Dunstabzugshaube sendet. In Abhängigkeit der vom Kochfeld ausgesendeten Signale wird der Gebläsemotor der Dunstabzugshaube in Betrieb gesetzt. Eine optische Übertragung der Signale ist im Kochfeldbereich aufgrund der Verschmutzungsgefahr der Übertragungselemente störungsanfällig.From the DE 40 41 798 C2 It is known that the operation of the hood automatically starts when the user has specified, for example by means of time delay and setting a cooking program on a cooker hood associated with the hob automatic operation of the hob. The hob is formed with an infrared transmitter, which sends signals to a photoelectric receiving element on the underside of the hood. Depending on the signals emitted by the cooktop, the fan motor of the extractor hood is put into operation. An optical transmission of the signals is in Hob area due to the risk of contamination of the transmission elements prone to failure.

Weiterhin ist es aus der DE 199 07 149 A1 bekannt, eine Dunstabzugshaube mit einer Dunsterfassungssensorik auszubilden.Furthermore, it is from the DE 199 07 149 A1 known to form a hood with a Dunsterfassungssensorik.

Aus der EP 1 223 286 A2 ist außerdem ein Verfahren zum Betrieb einer steuer- bzw. regelbare Dunstabzugshaube mit einem darunter angeordneten Kochfeld bekannt, wobei die Stromaufnahme des Kochfeldes mit einem oder mehreren Messwertaufnehmers erfasst wird und als Signal zum Steuern/Regeln der Absaugleistung der Dunstabzugshaube übermittelt wird. Ein solches Ausführungsbeispiel ist auch aus der DE 36 03 028 A1 bekannt. Hier liefert ein an die Zuleitung des Kochfeldes angreifender Stromwandler einen von der gesamten Stromaufnahme abhängigen Messwert über eine separate Steuerleitung an die Steuereinrichtung der Dunstabzugshaube.From the EP 1 223 286 A2 In addition, a method for operating a controllable or extractable hood with a cooking surface arranged below known, wherein the power consumption of the hob is detected with one or more transducer and is transmitted as a signal to control / regulate the suction of the hood. Such an embodiment is also known from DE 36 03 028 A1 known. Here, a current transformer acting on the supply line of the hob supplies a measured value dependent on the total current consumption via a separate control line to the control device of the extractor hood.

Die oben beschriebenen Beispiele aus dem Stand der Technik erfordern mit Ausnahme der WO 2006/097575 A1 zusätzliche Messwertaufnehmer für die Stromaufnahme, Temperaturfühler, Restfeuchtefühler etc., die Aktivitäten am Kochfeld erfassen und als Signal an eine Empfangseinrichtung der Dunstabzugshaube übermitteln. Bei der Ausführung gemäß WO 2006/097575 A1 erfolgt der Betrieb der Dunstabzugshaube in direkter Abhängigkeit der Einstellungen am Kochfeld. Nachteilig ist dabei, dass die Dunstabzugshaube direkt abgeschaltet oder in der Leistungsstufe reduziert wird, wenn am Kochfeld Veränderungen vorgenommen werden.The prior art examples described above require, with the exception of WO 2006/097575 A1 additional sensors for current consumption, temperature sensors, residual humidity sensors, etc., record the activities on the hob and transmit them as a signal to a receiving device of the extractor hood. In the execution according to WO 2006/097575 A1 The operation of the hood is directly dependent on the settings on the hob. A disadvantage is that the cooker hood is switched off directly or reduced in the power level when changes are made to the hob.

Der Erfindung liegt daher die Aufgabe zugrunde, eine steuer- und regelbare Dunstabzugshaube in Abhängigkeit vom Betriebszustand eines Kochfeldes und/oder Gargerätes sowie ein Verfahren zum Betrieb einer solchen Dunstabzugshaube derart zu gestalten, dass keine zusätzliche Messwertaufnehmer für die Erfassung des Betriebszustandes am Kochfeld oder Gargerät erforderlich sind und auf aufwändige sowie störungsempfindliche Signalübertragungselemente verzichtet werden kann und dass außerdem das Wrasenaufkommen in Abhängigkeit der Einstellungen im Betrieb des Kochfeldes für die Einstellungen der Leistungsstufen berücksichtigt werden kann.The invention is therefore based on the object to make a controllable and controllable cooker hood depending on the operating condition of a hob and / or cooking appliance and a method for operating such a hood so that no additional transducer for detecting the operating condition on the hob or cooking appliance required and can be dispensed with elaborate and interference-sensitive signal transmission elements and that also the Wrasenaufkommen depending on the settings in the operation of the hob for the settings of the power levels can be considered.

Erfindungsgemäß wird diese Aufgabe durch ein Verfahren zum Betrieb einer Dunstabzugshaube nach den Merkmalen des Anspruchs 1 gelöst. Zweckmäßige Weiterbildungen ergeben sich aus Anspruch 2.According to the invention, this object is achieved by a method for operating an extractor hood according to the features of claim 1. Advantageous developments emerge from claim 2.

Die mit der Erfindung erzielbaren Vorteile liegen insbesondere darin, dass eine oder mehrere am Kochfeld eingestellte Leistungsstufen für eine oder mehrere Kochstellen über ein im Kochfeld integriertes Kommunikationsmodul über das Stromnetz direkt an das in der Dunstabzugshaube integrierte Kommunikationsmodul an eine Auswerteeinrichtung übertragbar sind und in der Auswerteeinrichtung für eine Ansteuerung des Gebläsemotors derart ausgewertet werden, dass der Gebläsemotor nach dem Abschalten des Kochfeldes oder dem Verringern der Leistung am Kochfeld mit einer Nachlaufzeit weiter betrieben wird, so dass Wrasen und Gerüche auch nach dem Abschalten oder Verringern der Leistung des Kochfeldes entfernt werden. Dadurch erübrigen sich zusätzliche Messwertaufnehmer zur Erfassung des Wrasenaufkommens.The achievable with the invention advantages are in particular that one or more set on the hob power levels for one or more hotplates on a in the Cooktop integrated communication module via the mains directly to the built-in extractor hood communication module are transferable to an evaluation and evaluated in the evaluation for driving the fan motor so that the fan motor after switching off the hob or reducing the power on the hob with a lag time continues to operate, so that vapors and odors are removed even after switching off or reducing the power of the hob. This eliminates the need for additional transducers for the detection of Wrasenaufkommens.

In der Figur 1 ist eine automatisch und/oder manuell steuer- und regelbare Dunstabzugshaube 1 mit einer Bedieneinrichtung 2, einer Steuereinrichtung 3 zur Ansteuerung des Gebläsemotors 4 sowie einer Auswerteeinrichtung 5 in der Betriebszustände eines der Dunstabzugshaube 1 zugeordneten Kochfeldes 6 für die Ansteuerung des Gebläsemotors 4 ausgewertet werden, gezeigt. Die Bedieneinrichtung 2 für die manuelle Einstellung der Gebläseleistungsstufe ist mit der Steuereinrichtung 3 zur Ansteuerung des Gebläsemotors 4 verbunden. Die Dunstabzugshaube 1 ist mit einem Kommunikationsmodul 7 ausgebildet. Unter Kommunikationsmodul wird eine Komponente zur Übertragung (Übermittlung und/oder Empfang) von Gerätedaten und/oder Betriebszuständen auf das Stromnetz 8 verstanden.In the FIG. 1 is an automatic and / or manually controllable and controllable hood 1 with an operating device 2, a control device 3 for controlling the fan motor 4 and an evaluation device 5 in the operating conditions of the hood 1 associated hob 6 are evaluated for the control of the fan motor 4 shown , The operating device 2 for the manual adjustment of the blower power stage is connected to the control device 3 for controlling the fan motor 4. The extractor hood 1 is formed with a communication module 7. A communication module is a component for the transmission (transmission and / or reception) of device data and / or operating states to the power network 8.

Das Kochfeld 6 ist ebenfalls mit einem Kommunikationsmodul 9 ausgebildet. Die Kommunikationsmodule 7, 9 als Komponenten zur Übertragung von Gerätedaten und/oder Betriebszuständen auf das Stromnetz 8 sind für die Integration in vorgerüstete kommunikationsfähige Dunstabzugshauben 1 bzw. Kochfelder 6 zu deren Vernetzung ausgebildet. Das Kochfeld 6 weist mehrere Kochstellen 10 mit jeweils zugeordneten Bedieneinrichtungen 11 für die Einstellung von Leistungsstufen auf. Über das im Kochfeld 6 integrierte Kommunikationsmodul 9 werden eine oder mehrere an den Kochstellen 10 des Kochfeldes 6 eingestellte Leistungsstufen im Automatikbetrieb der Dunstabzugshaube 1 über das Stromnetz 8 an das Kommunikationsmodul 7 der Dunstabzugshaube 1 übermittelt und in der Auswerteeinrichtung 5 für eine Ansteuerung des Gebläsemotors 4 ausgewertet. Das Kommunikationsmodul 9 ist außerdem zur Übertragung von Gerätedaten ausgebildet. Mit Gerätedaten ist z.B. ein Identifikationssignal für die Beheizungsart des Kochfeldes (Induktion, Gas, Strahlungsheizkörper) gemeint. Ein derartiges Identifikationssignal ist für die Steuerung der Dunstabzugshaube 1 hinsichtlich der automatischen Anpassung der Gebläseleistung von Bedeutung. Ist z.B. ein Induktionskochfeld unter der Dunstabzugshaube angeordnet, wird das erhöhte Wrasenaufkommen aufgrund der geringeren Aufheizzeit schneller auftreten.The hob 6 is also formed with a communication module 9. The communication modules 7, 9 as components for the transmission of device data and / or operating states to the power grid 8 are designed for integration in pre-equipped communication-enabled extractor hoods 1 or cooktops 6 for their networking. The hob 6 has a plurality of cooking zones 10, each with associated operating devices 11 for the setting of power levels. About the integrated in the hob 6 communication module 9, one or more of the hotplates 10 of Hob 6 set power levels transmitted in the automatic mode of the hood 1 via the power supply 8 to the communication module 7 of the hood 1 and evaluated in the evaluation device 5 for controlling the fan motor 4. The communication module 9 is also designed to transmit device data. By device data is meant, for example, an identification signal for the type of heating of the hob (induction, gas, radiant heater). Such an identification signal is important for the control of the extractor hood 1 with regard to the automatic adjustment of the fan power. If, for example, an induction hob is arranged under the extractor hood, the increased vapor volume will occur more quickly due to the shorter heating time.

Wird das Kochfeld 6 mit beliebiger Leistungsstufe von mindestens einer Kochstelle 10 eingeschaltet, schaltet sich nach einigen Sekunden die Beleuchtung 12 der Dunstabzugshaube 1 ein. Nach einer Zeitverzögerung von z.B. ca. 1 Minute wird der Betrieb des Gebläsemotors 4 von der Steuereinrichtung 3 in einer erhöhten Gebläseleistungsstufe eingestellt und dann zeitverzögert in eine geringere Gebläseleistungsstufe zurückgesetzt. Über die Auswerteeinrichtung 5 und die Steuereinrichtung 3 wird der Betrieb der Dunstabzugshaube 1 in Bezug auf die Gebläseleistungsstufen während des Betriebes des Kochfeldes 6 entsprechend der Anzahl und der gewählten Leistungsstufen der Kochstellen 10 angepasst.If the hob 6 with any power level of at least one hob 10 is turned on, after a few seconds, the lighting 12 of the hood 1 a. After a time delay of e.g. About 1 minute, the operation of the fan motor 4 is set by the control device 3 in an increased fan power level and then reset time-delayed in a lower fan power level. Via the evaluation device 5 and the control device 3, the operation of the extractor hood 1 with respect to the fan power levels during operation of the hob 6 is adjusted according to the number and the selected power levels of the cooking zones 10.

Je höher die am Kochfeld 6 gewählte Leistungsstufe und/oder je mehr Kochstellen 10 eingeschaltet werden, desto höher ist die Gebläseleistungsstufe der Dunstabzugshaube1 im Automatikbetrieb vorgegeben. Bei Verringerung der Leistungsstufe am Kochfeld 6 wird im Normalfall auch die Gebläseleistungsstufe vorzugsweise zeitverzögert reduziert. Die Reaktion der Dunstabzugshaube 1 geschieht mit Verzögerung, da das Ändern der Leistungsstufe am Kochfeld 6 nicht unmittelbar zu weniger oder mehr Kochwrasen führt. Die Reaktion erfolgt innerhalb weniger Sekunden oder Minuten. Die Reaktion wird auch dadurch beeinflusst, dass die Kommunikation über das Stromnetz 8 zwischen Kochfeld 6 und Dunstabzugshaube 1 in Intervallen erfolgt.The higher the power level selected on the cooktop 6 and / or the more cooktops 10 are switched on, the higher the blower power level of the extractor hood 1 is set in automatic mode. When reducing the power level on the hob 6, the blower power stage is also reduced with a time delay in the normal case, preferably. The reaction of the hood 1 happens with delay, since changing the power level on the hob 6 does not lead directly to less or more cooking turf. The reaction takes place within a few seconds or minutes. The reaction is also influenced by the fact that the communication takes place via the power grid 8 between the hob 6 and cooker hood 1 at intervals.

Die Dunstabzugshaube1 ist vorrangig für den Automatikbetrieb in Abhängigkeit der am Kochfeld 6 eingestellten Leistungsstufen eingestellt. Der Automatikbetrieb kann allerdings zu jeder Zeit durch eine manuelle Betätigung der Bedieneinrichtung 2 der Dunstabzugshaube 1 unterbrochen werden (siehe Figur 2). Wird der Automatikbetrieb in der Leistungsstufe I zu einem Zeitpunkt t1 durch die manuelle Wahl einer höheren Gebläseleistungsstufe II unterbrochen, wird der Betrieb der Dunstabzugshaube 1 automatisch in den Automatikbetrieb zurückgesetzt, wenn innerhalb einer Zeit T1 (z. B. ca. 2 Minuten) keine weitere manuelle Betätigung der Bedieneinrichtung 2 der Dunstabzugshaube 1 erfolgt.The extractor hood 1 is primarily set for the automatic mode depending on the power levels set on the hob 6. However, the automatic mode can be interrupted at any time by a manual operation of the control device 2 of the hood 1 (see FIG. 2 ). If the automatic mode in the power stage I is interrupted at a time t1 by the manual selection of a higher fan power level II, the operation of the extractor hood 1 is automatically reset to automatic mode if no further one within a time T1 (eg about 2 minutes) manual actuation of the control device 2 of the hood 1 takes place.

Der Automatikbetrieb der Dunstabzugshaube 1 ist im Normalfall derart vorgegeben, dass eine Verringerung der Leistungsstufe am Kochfeld 6 (zeitverzögert) zu einer Verringerung der Gebläseleistungsstufe der Dunstabzugshaube 1 führt. Eine Ausnahme bildet ein Bratvorgang (siehe Figur 3) der von der Auswerteeinrichtung 5 der Dunstabzugshaube 1 anhand einer hohen Anfangsleistungsstufe (z.B. Leistungsstufe 12) von mindestens einer Kochstelle 10 erfasst wird, wenn diese hohe Leistungsstufe innerhalb einer vorgegeben Zeit T2 (z. B. ca. 0,5 bis 5 Minuten) auf eine wesentlich geringere Leistungsstufe (z.B. Leistungsstufe 6) reduziert wird. In diesem Fall wird die Gebläseleistungsstufe erhöht, da ein derartiger Leistungsstufenwechsel innerhalb einer in der Auswerteinrichtung 5 hinterlegten Zeit als Indiz für einen Bratvorgang mit erhöhtem Wrasenaufkommen gewertet wird. Die hohe Leistungsstufe der Dunstabzugshaube 1 ist manuell über die Bedieneinrichtung 2 der Dunstabzugshaube 1 in eine niedrigere Leistungsstufe zurücksetzbar.The automatic operation of the hood 1 is normally set such that a reduction in the power level on the hob 6 (delayed) leads to a reduction in the fan power level of the hood 1. An exception is a frying process (see FIG. 3 ) which is detected by the evaluation device 5 of the extractor hood 1 on the basis of a high initial power level (eg power level 12) of at least one hotplate 10, if this high power level within a predetermined time T2 (eg, about 0.5 to 5 minutes) a much lower power level (eg power level 6) is reduced. In this case, the blower power stage is increased, since such a power level change within a time stored in the evaluation device 5 is interpreted as an indication of a roasting process with increased Wrasenaufkommen. The high power level of the hood 1 can be reset manually via the operating device 2 of the hood 1 in a lower power level.

Wird das Kochfeld 6 komplett ausgeschaltet, wird die Dunstabzugshaube 1 zeitverzögert ebenfalls ausgeschaltet. Damit wird die Küchenluft von verbliebenen Wrasen und Gerüchen gereinigt. Wurde der Gebläsemotor 4 vor dem Ausschalten in einer hohen Gebläseleistungsstufe betrieben, ist in der Steuereinrichtung eine längere Nachlaufzeit als bei einer geringeren Gebläseleistungsstufe vorgegeben. Das Ausschalten der Gebläseleistung kann auch stufenweise erfolgen. Wird der Gebläsemotor 4 z.B. in der Gebläseleistungsstufe 3 zum Zeitpunkt des Ausschaltens der Kochstellen 10 betrieben, schaltet er nach ca. 1 Minute auf Stufe 2 zurück. Von Stufe 2 schaltet er nach ca. 2 Minuten in Stufe 1 und nach ca. 2 weiteren Minuten wird der Gebläsemotor 4 ausgeschaltet. Nach weiteren 30 Sekunden wird auch die Beleuchtung 12 ausgeschaltet.If the hob 6 is completely switched off, the extractor hood 1 is also switched off with a time delay. This cleans the kitchen air of remaining vapors and odors. If the blower motor 4 was operated before switching off in a high blower power stage, a longer follow-up time is given in the control device than at a lower blower power stage. Switching off the blower power can also be done gradually. If the fan motor 4 is e.g. operated in the blower power stage 3 at the time of switching off the hobs 10, it switches back to level 2 after about 1 minute. From level 2 it switches to level 1 after approx. 2 minutes and after approx. 2 further minutes the fan motor 4 is switched off. After another 30 seconds, the lighting 12 is turned off.
