Als Betriebszustand der Dunstabzugshaube wird ein Zustand bezeichnet, bei dem zumindest eine der Funktionen der Dunstabzugshaube zumindest zeitweise ausgefĆ¼hrt wird. Die Funktionen der Dunstabzugshaube werden in den unterschiedlichen BetriebszustƤnden nach unterschiedlichen Regeln ausgefĆ¼hrt. Die Dunstabzugshaube kann sich beispielsweise in den folgenden BetriebszustƤnden befinden beziehungsweise in diese gebracht werden. Ein Betriebszustand der Dunstabzugshaube ist die NormallĆ¼ftung, bei der eine LĆ¼fterstufe in der Regel von dem Benutzer gewƤhlt oder festgelegt wird. Ein weiterer Betriebszustand ist die IntervalllĆ¼ftung, bei der das LĆ¼ftergeblƤse nur in zeitlich beabstandeten Intervallen betrieben wird. Auch die NachlĆ¼ftung stellt einen Betriebszustand der Dunstabzugshaube dar. Hierbei wird das LĆ¼ftergeblƤse nach Ausschalten der Dunstabzugshaube noch fĆ¼r eine vorgegebene Zeitspanne weiter betrieben. Bei dem Betriebszustand der AutomatiklĆ¼ftung wird die LĆ¼fterleistung oder LĆ¼fterstufe durch Sensorsignale festgelegt, die beispielsweise durch einen Ultraschallsensor erfasst wurden. Die genannten BetriebszustƤnde der Dunstabzugshaube betreffen alle die Funktion der Dunstabzugshaube des Ansaugens von Luft, Wrasen und DĆ¼nsten. Allerdings kann die Dunstabzugshaube auch in einen weiteren Betriebszustand gebracht werden, bei dem durch die Beleuchtungseinrichtung ein Raum oder eine FlƤche ausgeleuchtet wird. Ein weiterer Betriebszustand ist die Funktion eines in der Dunstabzugshaube integrierten Kurzzeitweckers, umgangssprachlich auch Eieruhr genannt. Die unterschiedlichen BetriebszustƤnde der Dunstabzugshaube, die das Ansaugen von Luft, Wrasen und DĆ¼nsten betreffen, sowie der Betriebszustand des Beleuchtens als auch der Betriebszustand als Kurzzeitwecker kƶnnen auch in Kombination miteinander eingestellt werden.The operating state of the extractor hood is a state in which at least one of the functions of the extractor hood is carried out at least temporarily. The functions of the extractor hood are executed in different operating conditions according to different rules. The extractor hood can be located, for example, in the following operating states or brought into this. An operating state of the extractor hood is the normal ventilation, in which a fan level is usually selected or specified by the user. Another operating state is the interval ventilation, in which the fan blower is operated only at intervals spaced at intervals. The after-ventilation also represents an operating state of the extractor hood. In this case, the fan blower is still operated for a predetermined period of time after switching off the extractor hood. In the operating state of automatic ventilation, the fan power or fan level is determined by sensor signals that have been detected, for example, by an ultrasonic sensor. The above-mentioned operating conditions of the extractor hood all relate to the function of the extractor hood of the suction of air, vapors and steam. However, the extractor hood can also be brought into a further operating state in which a space or a surface is illuminated by the lighting device. Another operating state is the Function of an integrated in the hood short-time alarm clock, colloquially also called egg timer. The different operating states of the extractor hood, which relate to the intake of air, vapor and steam, as well as the operating state of the lighting and the operating state as a short-term alarm clock can also be set in combination with each other.

FĆ¼r jeden Betriebszustand bestehen mehrere Betriebsbedingungen, die insbesondere die Dauer und IntensitƤt der von der Dunstabzugshaube in diesem Betriebszustand auszufĆ¼hrenden Funktion beschreiben. Die Betriebsbedingungen sind somit insbesondere die IntensitƤt der LĆ¼fterleistung und/oder der Beleuchtung, die Dauer der LĆ¼ftung und/oder der Beleuchtung, die Zeitpunkte der LĆ¼ftung und/oder der Beleuchtung, die Erzeugung von Sensorsignalen durch Sensoren sowie Programme, die die Betriebsbedingungen der weiteren Funktionseinheiten einstellen.For each operating condition there are several operating conditions, which in particular describe the duration and intensity of the function to be performed by the extractor hood in this operating state. The operating conditions are thus in particular the intensity of the fan power and / or the lighting, the duration of the ventilation and / or lighting, the times of ventilation and / or lighting, the generation of sensor signals by sensors and programs that the operating conditions of the other functional units to adjust.

FĆ¼r den Betriebszustand der NormallĆ¼ftung ist die Betriebsbedingung beispielsweise die LĆ¼fterleistung. Bei der NachlauflĆ¼ftung kƶnnen als Betriebsbedingungen die Nachlaufdauer und NachlauflĆ¼fterleistung des LĆ¼ftergeblƤses eingestellt werden. Bei dem Betriebszustand der IntervalllĆ¼ftung kƶnnen die Intervalldauer (Zeitdauer, fĆ¼r die die LĆ¼ftung pro Intervall eingeschaltet ist), IntervallabstƤnde (Zeitdauer, fĆ¼r die die LĆ¼ftung pro Intervall ausgeschaltet ist) und IntervalllĆ¼fterleistung des LĆ¼ftergeblƤses als Betriebsbedingungen eingestellt werden. Bei dem Betriebszustand der Beleuchtung kann die BeleuchtungsintensitƤt der Beleuchtungseinrichtung als Betriebsbedingung eingestellt werden. Bei dem Betriebszustand als Kurzzeitwecker ist als Betriebsbedingung die Weckerlaufzeit einstellbar. SchlieƟlich kann bei einem Automatikbetrieb die LĆ¼fterleistung und Dauer der LĆ¼ftung als Betriebsbedingung eingestellt werden. Diese Betriebsbedingungen kƶnnen durch die Auswahl von Parametern einzeln aus vorgegebenen Werten gewƤhlt werden. So kann beispielsweise die LĆ¼fterleistung bei NormallĆ¼ftung durch Auswahl einer LĆ¼fterstufe eingestellt werden. Alternativ kƶnnen die Betriebsbedingungen aber auch durch Festlegen von Werten eingestellt werden. So kann beispielsweise die LĆ¼fterleistung feinstufig auf unterschiedliche Werte eingestellt werden. Diese Werte mĆ¼ssen im Gegensatz zu den erwƤhnten LĆ¼fterstufen nicht vorgegeben sein. Somit kann praktisch eine stufenlose Einstellung der Betriebsbedingungen erzielt werden. Zudem kƶnnen die Betriebsbedingungen auch in vorgegebenen Programmen teilweise zusammengefasst sein. Dies gilt insbesondere fĆ¼r die IntervalllĆ¼ftung, die NachlĆ¼ftung und den Automatikbetrieb.For the operating state of normal ventilation, the operating condition is, for example, the fan power. In the after-run ventilation, the run-on duration and the follow-up fan power of the fan blower can be set as operating conditions. In the operation mode of the interval ventilation, the interval time (duration for which ventilation is turned on per interval), interval distances (time period for which ventilation is turned off per interval), and fan ventilation interval fan output can be set as operating conditions. In the operating state of the illumination, the illumination intensity of the illumination device can be set as an operating condition. In the operating state as a short-term alarm, the alarm running time can be set as the operating condition. Finally, in an automatic mode, the fan power and duration of the ventilation can be set as the operating condition. These operating conditions can be selected individually from preset values by selecting parameters. For example, the fan power at normal ventilation can be set by selecting a fan level. Alternatively, the operating conditions can also be set by setting values. For example, the fan power can be finely adjusted to different values. These values do not have to be specified in contrast to the fan levels mentioned. Thus, practically a stepless adjustment of the operating conditions can be achieved. In addition, the operating conditions in some programs can partially be summarized. This applies in particular to the interval ventilation, the after-ventilation and the automatic mode.

Als Einstellen eines Betriebszustandes wird erfindungsgemƤƟ die Auswahl des Betriebszustandes und das Einstellen der Betriebsbedingung oder Betriebsbedingungen des Betriebszustandes verstanden. Als Einstellen der Betriebsbedingungen wird erfindungsgemƤƟ das WƤhlen oder Festlegen von Parametern der Betriebsbedingung verstanden, wobei das Einstellen vorzugsweise durch Auswahl eines festgelegten Programms mit festen Parameterwerten erfolgt.As setting of an operating state, the selection of the operating state and the setting of the operating condition or operating conditions of the operating state is understood according to the invention. In accordance with the invention, the setting of the operating conditions is understood as the selection or definition of parameters of the operating condition, wherein the setting preferably takes place by selecting a fixed program with fixed parameter values.

Die Funktionseinheiten, mit denen das zentrale Stellelement verbunden ist, kƶnnen eine LĆ¼ftergeblƤseeinheit, eine Beleuchtungseinheit, eine Steuereinheit und/oder einer Messeinheit der Dunstabzugshaube sein. Durch die Verbindung mit diesen Einheiten kƶnnen alle fĆ¼r die unterschiedlichen BetriebszustƤnde erforderlichen Betriebsbedingungen Ć¼ber das zentrale Stellelement eingestellt werden. Vorzugsweise ist das zentrale Stellelement mit einer Steuereinheit als Funktionseinheit verbunden, die in AbhƤngigkeit der BetƤtigung des zentralen Stellelementes die Bedingungen, wie beispielsweise die LĆ¼fterstufe und LĆ¼ftungsdauer einstellt. FĆ¼r die Einstellung der Betriebsbedingungen kƶnnen hierzu in der Steuereinheit Programme hinterlegt sein, in denen die Werte der einzelnen Bedingungen festgelegt sind. Bei Einstellung eines solchen Programms Ć¼ber das Stellelement werden die entsprechenden Bedingungen an der entsprechenden Funktionseinheit, beispielsweise dem LĆ¼ftergeblƤse, eingestellt.The functional units, with which the central control element is connected, may be a fan blower unit, a lighting unit, a control unit and / or a measuring unit of the extractor hood. Through the connection with these units, all operating conditions required for the different operating conditions can be set via the central control element. Preferably, the central control element is connected to a control unit as a functional unit, which adjusts the conditions, such as the fan speed and ventilation time depending on the operation of the central control element. In order to set the operating conditions, programs may be stored in the control unit for this purpose, in which the values of the individual conditions are defined. When setting such a program on the actuator, the appropriate conditions on the appropriate functional unit, such as the fan blower set.

Indem bei der erfindungsgemƤƟen Dunstabzugshaube die Bedieneinheit hinter einer Blende angeordnet ist, sind DurchbrĆ¼che oder DurchlƤsse in der Blende, wie diese beim Stand der Technik fĆ¼r TastenstĆ¶ĆŸel erforderlich sind, nicht notwendig. Dadurch wird eine ebene durchgehende OberflƤche beziehungsweise FrontflƤche der Blende geschaffen beziehungsweise erhalten und dadurch der Aufbau der Dunstabzugshaube vereinfacht. Neben der einfacheren Herstellung bringt die durchgehende Blende auch den Vorteil mit sich, dass diese einfach gereinigt werden kann.By the control unit is arranged behind a panel in the hood according to the invention, openings or passages in the aperture, as they are required in the prior art for key plunger, not necessary. As a result, a flat continuous surface or front surface of the panel is created or obtained and thereby simplifies the construction of the hood. In addition to the ease of manufacture, the continuous aperture also has the advantage that it can be easily cleaned.

Da erfindungsgemƤƟ weiterhin ein einziges Stellelement fĆ¼r das Einstellen von Betriebsbedingungen von mindestens zwei BetriebszustƤnden der Dunstabzugshaube vorgesehen ist, kƶnnen Bedienelemente, Ć¼ber die die BetriebszustƤnde ausgewƤhlt werden kƶnnen, einfach ausgestaltet sein. Insbesondere bedĆ¼rfen diese keiner zusƤtzlichen Funktion, wie beispielsweise der MehrfachbetƤtigung zur Auswahl einer LĆ¼fterstufe. Hierdurch wird der Aufbau der Dunstabzugshaube im Bereich der Bedieneinheit weiter vereinfacht.Since, according to the invention, a single control element for setting operating conditions of at least two operating states of the extractor hood is furthermore provided, control elements via which the operating states can be selected can be simply designed. In particular, these require no additional function, such as the multiple operation to select a fan level. This further simplifies the construction of the extractor hood in the area of the operating unit.

SchlieƟlich wird in der erfindungsgemƤƟen Dunstabzugshaube als Stellelement ein berĆ¼hrungslos betƤtigbares Stellelement verwendet. Das Stellelement kann hierzu insbesondere kapazitiver NƤherungsschalter oder NƤhrerungssensoren umfassen. Die Verwendung eines solchen Stellelementes erlaubt die Anordnung des Stellelementes als Teil der Bedieneinheit hinter einer durchgehenden Blende. Hierdurch wird das Stellelement vor Verunreinigungen und mechanischen Belastungen geschĆ¼tzt, ohne dass separate Dichtungen oder Abdeckungen notwendig sind. Somit wird der Aufbau der Dunstabzugshaube im Bereich der Bedieneinheit weiter vereinfacht.Finally, in the extractor hood according to the invention as a control element, a contactless operable actuator used. For this purpose, the adjusting element can in particular comprise capacitive proximity switches or nutrient sensors. The use of such a control element allows the arrangement of the control element as part of the control unit behind a continuous panel. As a result, the actuator is protected from contamination and mechanical loads without separate seals or covers are necessary. Thus, the construction of the hood in the control unit is further simplified.

ErfindungsgemƤƟ stellt das Stellelement einen Schiebeschalter ohne mechanisch verschiebbare Elemente dar. Insbesondere wird das Stellelement durch einen Stellstreifen, insbesondere kapazitiven Stellstreifen, gebildet. Hierbei kƶnnen durch AnnƤherung an den Stellstreifen oder Bewegung entlang des Stellstreifens unterschiedliche Stellwerte erzeugt werden, die als Parameter fĆ¼r die einzelnen Betriebsbedingungen dienen kƶnnen. Der Vorteil dieser AusfĆ¼hrungsform liegt insbesondere darin, dass eine Vielzahl unterschiedlicher Parameterwerte erzeugt werden kƶnnen und somit auch ein feinstufiges Einstellen, das auch als stufenloses Einstellen von Betriebsbedingungen der BetriebszustƤnde bezeichnet wird, realisiert werden kann. Ein entsprechender Vorteil kann auch mit einem Stellelement erzielt werden, bei dem eine Rotation beziehungsweise ein Winkelwert der AnnƤherung erkannt wird. Alternativ ist das Stellelement so ausgestaltet, dass bei BetƤtigung des Stellelementes von einem vorgegebenen Wert oder Programm auf einen anderen vorgegebenen Wert oder ein anderes vorgegebenes Programm gesprungen wird. Beispielsweise kann zunƤchst als Betriebszustand die NachlĆ¼ftung ausgewƤhlt und dann Ć¼ber das Stellelement die gewĆ¼nschten Parameter eingegeben. Dies kann beispielsweise durch Auswahl eines Programms erfolgen, bei dem voreingestellt ist, dass die NachlĆ¼ftung fĆ¼r 5 Minuten auf LĆ¼fterstufe 3 erfolgt.According to the invention, the control element is a slide switch without mechanically displaceable elements. In particular, the control element is formed by a control strip, in particular capacitive control strip. Here, by approaching the control strip or movement along the control strip different control values can be generated, which can serve as parameters for the individual operating conditions. The advantage of this embodiment is, in particular, that a large number of different parameter values can be generated and thus also a fine-level setting, which is also referred to as infinitely variable adjustment of operating conditions of the operating states, can be realized. A corresponding advantage can also be achieved with an actuating element, in which a rotation or an angle value of the approach is detected. Alternatively, the control element is designed so that when the control element is actuated, it jumps from a predetermined value or program to another predetermined value or another predetermined program. For example, the after-ventilation can first be selected as the operating state and then the desired parameters can be entered via the control element. This can be done, for example, by selecting a program in which the default setting is that the after-ventilation takes place for 5 minutes at fan level 3.

Das Stellelement der Bedieneinheit ist erfindungsgemƤƟ mit mindestens zwei Auswahlelementen zur Auswahl mindestens eines Betriebszustandes der Dunstabzugshaube verbunden sein. Diese Auswahlelemente sind separat zu dem zentralen Stellelement angeordnet und kƶnnen separat von dem zentralen Stellelement betƤtigt werden. Durch Auswahl eines Betriebszustandes der Dunstabzugshaube mittels des Auswahlelementes wird gewƤhrleistet, dass Eingabewerte, die Ć¼ber das Stellelement erzeugt werden, fĆ¼r den entsprechenden Betriebszustand verwendet werden. Das oder die separaten Auswahlelemente sind erfindungsgemƤƟ als BerĆ¼hrungs- oder NƤherungssensorelemente ausgestaltet. Durch eine solche Ausgestaltung der Auswahlelemente ist auch in diesem Bereich ein Durchlass, beispielsweise fĆ¼r TastenstĆ¶ĆŸel, in der Blende nicht erforderlich.The actuator of the control unit is inventively be connected to at least two selection elements for selecting at least one operating state of the hood. These selection elements are arranged separately from the central control element and can be actuated separately from the central control element. By selecting an operating state of the extractor hood by means of the selection element, it is ensured that input values which are generated via the actuating element are used for the corresponding operating state. The one or more separate selection elements are designed according to the invention as touch or proximity sensor elements. By such an embodiment of the selection elements a passage, for example for key tappet, in the panel is not required in this area.

Die Dunstabzugshaube weist vorzugsweise einen Gleichstrommotor als Antrieb des LĆ¼ftergeblƤses der Dunstabzugshaube auf. Der Gleichstrommotor kann dabei Ć¼ber das Stellelement feinstufig eingestellt werden. Das Einstellen des Gleichstrommotors stellt insbesondere die Einstellung von Betriebsbedingungen des Gleichstrommotors auf unterschiedliche Werte dar. Diese Werte mĆ¼ssen nicht vorgegeben sein sondern kƶnnen von dem Benutzer frei gewƤhlt werden. Somit kann praktisch eine stufenlose Einstellung der Betriebsbedingungen des Betriebszustandes der BelĆ¼ftung erzielt werden. Diese AusfĆ¼hrungsform weist den Vorteil auf, dass die Leistung des LĆ¼ftergeblƤses exakt auf die gegenwƤrtigen Bedingungen in dem Raum, in dem die Dunstabzugshaube betrieben wird, eingestellt werden kann und somit der Energiebedarf minimiert werden kann.The extractor hood preferably has a DC motor as the drive of the fan blower of the extractor hood. The DC motor can be finely adjusted via the actuator. The setting of the DC motor in particular represents the setting of operating conditions of the DC motor to different values. These values need not be predetermined but can be freely selected by the user. Thus, practically a stepless adjustment of the operating conditions of the operating state of the ventilation can be achieved. This embodiment has the advantage that the performance of the fan blower can be adjusted precisely to the current conditions in the room in which the extractor hood is operated and thus the energy requirement can be minimized.

GemƤƟ einer bevorzugten AusfĆ¼hrungsform umfasst die Dunstabzugshaube eine Beleuchtungseinheit, die mit dem Stellelement so verbunden ist, dass zumindest eine Betriebsbedingung des Betriebszustandes der Beleuchtung feinstufig eingestellt werden kann. Auch in diesem Zusammenhang kƶnnen die Werte der Betriebsbedingungen der Beleuchtung vom Benutzer frei gewƤhlt werden. Das feinstufige Einstellen der Betriebsbedingungen entspricht daher einer praktisch stufenlosen Einstellung der Werte. Wird von dem Benutzer die Betriebsbedingung der IntensitƤt der Beleuchtung Ć¼ber das Stellelement eingestellt, so stellt das feinstufige Einstellen ein Dimmen der Beleuchtung dar.According to a preferred embodiment, the extractor hood comprises a lighting unit which is connected to the actuating element so that at least one operating condition of the operating state of the lighting can be adjusted in a finely graduated manner. Also in this context, the values of the operating conditions of the lighting can be freely selected by the user. The fine-tuning of the operating conditions therefore corresponds to a virtually continuous adjustment of the values. If the operating condition of the intensity of the illumination is set by the user via the adjusting element, then the fine-level setting represents a dimming of the illumination.

GemƤƟ einer AusfĆ¼hrungsform ist die Blende durch unterschiedliche OberflƤchenbehandlung in einen Bedienbereich, hinter dem die Bedieneinheit angeordnet ist, und einen Informationsausgabebereich aufgeteilt. Durch die unterschiedliche Behandlung der OberflƤchen in dem Bedienbereich und dem Informationsausgabebereich kann den unterschiedlichen Anforderungen an diese Bereiche Rechnung getragen werden. So ist es fĆ¼r bei einer durchgehenden Blende von Bedeutung, dass diese im Informationsausgabebereich InformationsflƤchen aufweist, Ć¼ber die Zustandsangaben oder Einstellungsangaben ausgegeben, insbesondere angezeigt werden kƶnnen. In dem Bedienbereich hingegen ist hinter der Blende die Bedieneinheit vorgesehen. In diesem Bereich sollten daher bei einer durchsichtigen Blende die Bedieneinheit und deren Komponenten weitestgehend verdeckt sein. Indem die Bereiche durch OberflƤchenbehandlung gebildet werden, ist das Vorsehen einer separaten Verkleidung, beispielsweise eines Abdeckbleches fĆ¼r den Bedienbereich nicht erforderlich. Zudem ist die gemƤƟ dieser AusfĆ¼hrungsform durch OberflƤchenbehandlung in zwei Bereiche unterteilte Blende einteilig und kann somit zu Montage- und Reparaturzwecken einfach eingesetzt und entnommen werden, was bei einem separaten Abdeckblech nicht der Fall ist.According to an embodiment, the aperture is divided by different surface treatment into an operating area, behind which the operating unit is arranged, and an information output area. Due to the different treatment of the surfaces in the operating area and the information output area, the different requirements for these areas can be taken into account. Thus, it is important for a continuous diaphragm that it has information areas in the information output area, via which status information or settings information can be output, in particular displayed. In the operating area, however, the control unit is provided behind the panel. In this area, the operating unit and its components should therefore be largely concealed with a transparent panel. By forming the areas by surface treatment, it is not necessary to provide a separate cladding, for example a cover panel for the operating area. In addition, the panel divided into two areas according to this embodiment is one-piece and thus can be easily used and removed for assembly and repair purposes, which is not the case with a separate cover plate.

Die OberflƤchenbehandlung stellt insbesondere ein Beschichten dar. Bevorzugt stellt die OberflƤchenbehandlung das Aufbringen einer Schicht mittels Drucken, insbesondere Siebdruck, oder Kleben, insbesondere Kaschieren oder Laminieren, dar. Der Vorteil dieser Beschichtungsarten besteht darin, dass die Bereiche individuell gestaltet sein kƶnnen, so kƶnnen beispielsweise in dem Bedienbereich in einer Folie oder Schicht Symbole fĆ¼r Auswahlelemente oder andere Symbole eingebracht oder ausgespart sein. Die Herstellung einer solchen Schicht kann durch Druckverfahren erfolgen.The surface treatment is in particular a coating. The surface treatment preferably represents the application of a layer by means of printing, in particular screen printing, or gluing, in particular laminating or laminating. The advantage of these types of coatings is that the regions can be designed individually, for example in the operating area in a foil or layer symbols for selection elements or other symbols are introduced or omitted. The production of such a layer can be effected by printing processes.

Vorzugsweise stellt die Schicht, mit der die Blende im Bedienbereich beschichtet ist, eine metallische Schicht dar. Die metallische Schicht kann ein Edelstahlblech oder Aluminiumblech geringer Dicke oder ein Druckschicht oder Folie sein, in der metallische Farbpigmente enthalten sind. Durch die Wahl eines metallischen Materials kann der Einblick in das Innere der Dunstabzugshaube durch die Blende verhindert werden. Zudem fĆ¼gt sich eine solche Beschichtung in das Gesamterscheinungsbild der Dunstabzugshaube, die in der Regel aus Metallblech hergestellt ist, ein. Ist die Schichtdicke der metallischen Schicht hinreichend dĆ¼nn, betrƤgt diese beispielsweise 2mm oder weniger, so kann die Beschichtung des Bedienbereiches durchgehend sein. Insbesondere im Bereich des Stellelementes und Auswahlelementen kann bei einer geringen Schichtdicke die BetƤtigung der Elemente durch die mit der Schicht versehene Blende erfolgen. Es ist allerdings auch mƶglich, dass in der Schicht in dem Bereich des Stellelementes und von Auswahlelementen Aussparungen vorgesehen sind.Preferably, the layer with which the diaphragm is coated in the operating region, a metallic layer. The metallic layer may be a stainless steel sheet or aluminum sheet of small thickness or a printing layer or film containing metallic color pigments. By choosing a metallic material, the insight into the interior of the hood through the aperture can be prevented. In addition, such a coating adds to the overall appearance of the hood, which is usually made of sheet metal, a. If the layer thickness of the metallic layer is sufficiently thin, this is for example 2mm or less, the coating of the operating area may be continuous. In particular, in the region of the actuating element and selection elements, the actuation of the elements can take place through the diaphragm provided with the layer with a small layer thickness. However, it is also possible for recesses to be provided in the layer in the region of the adjusting element and of selection elements.

Die Blende kann in dem Bedienbereiche an der Frontseite und/oder der RĆ¼ckseite oberflƤchenbehandelt sein. Bei einer reinen Behandlung an der Frontseite oder der RĆ¼ckseite wird die aufgebrachte Schicht eine metallische Schicht darstellen. Ist die Blende in dem Bedienbereich sowohl an der Vorderseite als auch an der RĆ¼ckseite oberflƤchenbehandelt, so kann an der RĆ¼ckseite zusƤtzlich ein schwarzweiƟ Hinterdruck vorgesehen sein. Dies weist den Vorteil auf, dass der Ɯbergang zwischen dem Bedienbereich und dem Informationsausgabebereich an der RĆ¼ckseite bei der OberflƤchenbehandlung nicht zu berĆ¼cksichtigen ist und diese Ć¼ber deren gesamten FlƤche mit einer Schicht versehen werden kann.The bezel may be surface treated in the operating areas on the front side and / or the rear side. In a pure treatment on the front or the back, the applied layer will be a metallic layer. If the panel in the operating area is surface-treated both on the front side and on the rear side, a black-and-white backprint can additionally be provided on the rear side. This has the advantage that the transition between the operating area and the information output area on the rear side is not taken into account in the surface treatment and that it can be provided with a layer over its entire area.

Die erfindungsgemƤƟ verwendete Blende besteht aus einem Material, das als Dielektrikum dienen kann. Insbesondere wird ein transparentes Dielektrikum verwendet. Die Blende kann daher beispielsweise aus Glas oder Kunststoff bestehen. Durch die Verwendung dieses Materials kƶnnen das Stellelement und gegebenenfalls vorgesehene Auswahlelemente als NƤherungssensoren ausgebildet sein, fĆ¼r die die Blende als Dielektrikum dient.The diaphragm used in the invention consists of a material which can serve as a dielectric. In particular, a transparent dielectric is used. The panel can therefore be made of glass or plastic, for example. By using this material, the adjusting element and possibly provided selection elements can be designed as proximity sensors for which the diaphragm serves as a dielectric.

Vorzugsweise stellt die Dunstabzugshaube eine Esse dar und die Blende bildet die gesamte Vorderseite des Sichtschirms der Esse. Hierdurch wird der Aufbau der Dunstabzugshaube weiter vereinfacht.Preferably, the hood is a dining and the panel forms the entire front of the screen of the Esse. This further simplifies the construction of the extractor hood.

Die Erfindung wird im Folgenden erneut unter Bezugnahme auf die beiliegenden Zeichnungen genauer erlƤutert. Es zeigen:

In Figur 1 ist ein Teil einer Dunstabzugshaube 1 gemƤƟ einer AusfĆ¼hrungsform der vorliegenden Erfindung gezeigt. Die Dunstabzugshaube 1 umfasst einen Sichtschirm 2, der auch als Wrasenschirm oder Schirm bezeichnet wird, sowie einen sich von dem Sichtschirm 2 nach oben erstreckenden Kamin 3. In der Figur 1 ist der Ausschnitt des Sichtschirms 2 im Bereich unterhalb des Kamins dargestellt. Die Dunstabzugshaube 1 stellt eine Esse, insbesondere eine Inselesse oder eine Wandesse dar. Der Sichtschirm 2 weist eine flache Kastenform auf. Die Vorderseite des Sichtschirms 2 wird durch eine Blende 20 gebildet, die sich Ć¼ber die gesamte Hƶhe und Breite des Sichtschirms 2 erstreckt.In FIG. 1 Figure 1 shows part of an extractor hood 1 according to an embodiment of the present invention. The extractor hood 1 comprises a viewing screen 2, which is also referred to as Wrasenschirm or screen, as well as from the viewing screen 2 upwardly extending chimney 3. In the FIG. 1 the section of the screen 2 is shown in the area below the chimney. The extractor hood 1 represents a dining, in particular a island fair or a Wandesse. The viewing screen 2 has a flat box shape. The front of the viewing screen 2 is formed by a diaphragm 20 which extends over the entire height and width of the viewing screen 2.

Die Blende 20 ist eine durchgehende Glasplatte, bei der ein oberer Informationsausgabebereich 21 und ein unterer Bedienbereich 22 vorgesehen sind. In der dargestellten AusfĆ¼hrungsform erstrecken sich der Informationsausgabebereich 21 und der Bedienbereich 22 Ć¼ber die gesamte Breite des Sichtschirms 2.The bezel 20 is a continuous glass plate in which an upper information output section 21 and a lower operation section 22 are provided. In the illustrated embodiment, the information output area 21 and the operation area 22 extend over the entire width of the viewing screen 2.

Im Informationsausgabebereich 21 ist ein Anzeigebereich 211 vorgesehen. In diesem Bereich 211 sind hinter der Blende 20 oder in die Blende 20 eingearbeitete Anzeigevorrichtungen 2111 vorgesehen. Die Anzeigevorrichtungen kƶnnen Sieben-Segment-Anzeigen, Symbolanzeigen oder eine Klartextanzeigen sein. Insbesondere ist die Anzeigevorrichtung 2111 so ausgelegt, dass diese sowohl die eingestellte LĆ¼fterstufe als auch die eingestellte BeleuchtungsintensitƤt anzeigt.In the information output area 21, a display area 211 is provided. In this area 211 20 incorporated behind the panel 20 or in the aperture 20 display devices 2111 are provided. The display devices may be seven-segment displays, symbol displays or plain text displays. In particular, the display device 2111 is designed such that it displays both the set fan level and the set illumination intensity.

Im Bedienbereich ist zentral, das heiƟt in der Mitte der Breite des Sichtschirms 2 ein Stellelement 221 vorgesehen. Diese bildet den Teil einer Bedieneinrichtung. Das Stellelement 221 ist hinter der Blende 2 angeordnet und dessen Position ist an der Frontseite 201 der Blende 2 durch Markierungen gekennzeichnet.In the operating area is central, that is, in the middle of the width of the viewing screen 2, an adjusting element 221 is provided. This forms the part of an operating device. The actuator 221 is disposed behind the panel 2 and its position is marked on the front side 201 of the panel 2 by markings.

Seitlich neben dem Stellelement 221 sind Auswahlelemente 222, 223, 224, 225 angeordnet. Diese Auswahlelemente 222, 223, 224, 225 sind insbesondere durch hinter der Blende 2 angeordnete Sensorelemente gebildet. Das Auswahlelement 222 dient zum Ein- und Ausschalten der Dunstabzugshaube 1. Das Auswahlelement 223 dient zur Auswahl des Betriebszustandes der NormallĆ¼ftung und das Auswahlelement 224 dient zur Auswahl des Betriebszustandes der Beleuchtung. Das Auswahlelement 225 dient zur Einstellung des Betriebszustandes der NachlĆ¼ftung.On the side of the adjusting element 221 selection elements 222, 223, 224, 225 are arranged. These selection elements 222, 223, 224, 225 are formed in particular by sensor elements arranged behind the diaphragm 2. The selection element 222 serves to switch the extractor hood 1 on and off. The selection element 223 serves to select the operating state of the normal ventilation, and the selection element 224 serves to select the operating state of the lighting. The selection element 225 is used to set the operating state of the after-ventilation.

Sobald eines der Auswahlelemente betƤtigt wird, kƶnnen Ć¼ber das Stellelement 221 Betriebsbedingungen fĆ¼r den gewƤhlten Betriebszustand eingestellt werden. Wird beispielsweise das Auswahlelement 223 betƤtigt, werden die Ć¼ber das Stellelement 221 eingegebenen Werte zur Einstellung der LĆ¼fterstufe, der LĆ¼fterleistung oder eines LĆ¼fterprogramms verwendet. Die Tatsache, dass die NormallĆ¼ftung ausgewƤhlt ist kann beispielsweise durch Aufleuchten des Symbols in dem Bedienbereich 22 angezeigt werden. In dem Anzeigebereich 211 wird darĆ¼ber hinaus die derzeit ausgewƤhlte oder eingestellte LĆ¼fterstufe angezeigt. Wird hingegen das Auswahlelement 224 betƤtigt, wird bei BetƤtigung des Stellelementes 221 die IntensitƤt der Beleuchtung eingestellt. Bei BetƤtigung des Auswahlelementes 225 kann durch das Stellelement 221 die Zeitdauer und/oder die IntensitƤt der BelĆ¼ftung und/oder der Beleuchtung wƤhrend einer Nachlaufphase eingestellt werden. Vorzugsweise sind die Parameter fĆ¼r die Betriebsbedingungen bei der NachlĆ¼ftung in Form von Programmen hinterlegt, so dass Ć¼ber das Stellelement 221 nur ein Programm ausgewƤhlt wird und entsprechend dem Programm die Dauer und IntensitƤt der NachlĆ¼ftung eingestellt wird. Wird hingegen das Auswahlelement 223 betƤtigt, wird bei BetƤtigung des Stellelementes 221 die LĆ¼fterleistung stufenlos oder feinstufig eingestellt. Die eingestellte LĆ¼fterleistung wird in dem Anzeigebereich 211 angezeigt. Wird das Auswahlelement 224 betƤtigt, wird bei BetƤtigung des Stellelementes 221 die LichtintensitƤt variiert. Auch die eingestellte LichtintensitƤt wird in dem Anzeigebereich 211 angezeigt. Somit kann mit der erfindungsgemƤƟen Dunstabzugshaube Ć¼ber ein einziges berĆ¼hrungslos betƤtigbares Stellelement die LĆ¼fterleistung und die BeleuchtungsintensitƤt angezeigt und durch einen gemeinsamen Anzeigebereich 211 angezeigt werden.As soon as one of the selection elements is actuated, operating conditions for the selected operating state can be set via the adjusting element 221. If, for example, the selection element 223 is actuated, the values entered via the control element 221 are used to set the fan level, the fan power or a fan program. The fact that the normal ventilation is selected can be indicated, for example, by lighting the symbol in the operating area 22. In the display area 211, moreover, the currently selected or set fan level is displayed. If, on the other hand, the selection element 224 is actuated, the intensity of the illumination is set when the adjustment element 221 is actuated. Upon actuation of the selection element 225, the time period and / or the intensity of the ventilation and / or the illumination during a follow-up phase can be adjusted by the adjusting element 221. Preferably, the parameters for the operating conditions during the after-ventilation are stored in the form of programs, so that only one program is selected via the control element 221 and the duration and intensity of the after-ventilation is set in accordance with the program. If, on the other hand, the selection element 223 is actuated, the fan power is adjusted steplessly or finely stepped upon actuation of the adjusting element 221. The set fan power is displayed in the display area 211. If the selection element 224 is actuated, the light intensity is varied upon actuation of the adjusting element 221. Also, the set light intensity is displayed in the display area 211. Thus, the fan power and the illumination intensity can be displayed and displayed by a common display area 211 with the hood according to the invention via a single non-contact actuable actuator.

In Figur 4 ist ein schematisches Blockschaubild von Funktionseinheiten einer Dunstabzugshaube 1 gezeigt und dargestellt, wie nach einer AusfĆ¼hrungsform der Erfindung die Verbindung zwischen dem Stellelement 221 und den Funktionseinheiten ausgestaltet sein kann. Wie sich aus Figur 4 ergibt ist nach dieser AusfĆ¼hrungsform der Dunstabzugshaube 1 das zentrale Stellelement 221 mit einer Steuereinheit 10, die in der dargestellten AusfĆ¼hrungsform eine zentrale Dunstabzugshaubensteuerung ist, verbunden. Ɯber diese Steuereinheit 10 ist das Stellelement 4 weiterhin mit der LĆ¼ftergeblƤseeinheit 11, der Beleuchtungseinheit 12 sowie einer Timer-Einheit 13 und einer Sensoreinheit 14 verbunden.In FIG. 4 a schematic block diagram of functional units of an extractor hood 1 is shown and illustrated how, according to one embodiment of the invention, the connection between the actuator 221 and the functional units can be configured. As it turned out FIG. 4 According to this embodiment, the extractor hood 1 is connected to the central actuating element 221 with a control unit 10, which in the illustrated embodiment is a central extractor hood control. About this control unit 10, the control element 4 is further connected to the fan blower unit 11, the lighting unit 12 and a timer unit 13 and a sensor unit 14.

Wird beispielsweise der Betriebszustand der NachlĆ¼ftung ausgewƤhlt, so kann Ć¼ber das Stellelement 221 die LĆ¼fterintensitƤt durch Auswahl eines Programms, das in der Steuereinheit 10 hinterlegt ist, gewƤhlt werden. Die entsprechende LĆ¼fterleistung wird dann Ć¼ber das SteuergerƤt 10 an der LĆ¼ftergeblƤseeinheit 11 eingestellt. Auch die Betriebsbedingungen der weiteren BetriebszustƤnde der Dunstabzugshaube 1 kƶnnen auf diese Weise eingestellt werden.If, for example, the operating state of the post-ventilation is selected, the fan intensity can be selected via the control element 221 by selecting a program stored in the control unit 10. The corresponding fan power is then set via the controller 10 to the fan blower unit 11. The operating conditions of the other operating conditions of the hood 1 can be adjusted in this way.

In den Figuren 2 und 3 ist der Aufbau der Blende 20 der Dunstabzugshaube 1 unterschiedlicher AusfĆ¼hrungsformen gezeigt. In der in Figur 2 gezeigten AusfĆ¼hrungsform ist die Blende 20 an deren RĆ¼ckseite 202 im oberen Bereich schwarz hinterdruckt. Die durch das Drucken aufgebrachte Schicht ist mit der Bezugsziffer 212 bezeichnet. Im unteren Bereich ist die RĆ¼ckseite 202 der Blende 20 metallisch bedruckt oder mit einem dĆ¼nnen Edelstahlblech kaschiert. Diese metallische Schicht ist mit dem Bezugszeichen 226 bezeichnet.In the FIGS. 2 and 3 the construction of the aperture 20 of the hood 1 of different embodiments is shown. In the in FIG. 2 In the embodiment shown, the panel 20 is backprinted black on the rear side 202 in the upper area. The layer applied by printing is designated by the reference numeral 212. In the lower area, the back 202 of the panel 20 is printed metallic or laminated with a thin stainless steel sheet. This metallic layer is designated by reference numeral 226.

In der in Figur 3 gezeigten AusfĆ¼hrungsform ist die RĆ¼ckseite 202 der Blende 20 vollstƤndig schwarz hinterdruckt. Hierdurch wird eine durchgehende Schicht 2021 auf der RĆ¼ckseite 202 der Blende 20 gebildet. An der Frontseite 201 der Blende 20 ist im unteren Bereich ein Edelstahlblech 227 aufkaschiert. Die Dicke des Edelstahlbleches ist gering und kann beispielsweise 2mm oder weniger betragen. Die Schichtdicke eines aufkaschierten Bleches wird erfindungsgemƤƟ so gering gewƤhlt, wie dies technisch realisierbar ist.In the in FIG. 3 In the embodiment shown, the rear side 202 of the panel 20 is completely black-backed. As a result, a continuous layer 2021 is formed on the rear side 202 of the diaphragm 20. On the front side 201 of the panel 20, a stainless steel sheet 227 is laminated in the lower area. The thickness of the stainless steel sheet is small and may be, for example, 2mm or less. The layer thickness of a laminated sheet is chosen according to the invention as low as technically feasible.

Da die Bereiche 21 und 22 lediglich durch OberflƤchenbehandlung, insbesondere durch das Aufbringen dĆ¼nner Schichten auf die Frontseite 201 und/oder die RĆ¼ckseite 202 der Blende 20 erzeugt werden, ist es nicht erforderlich an der Frontseite 201 zusƤtzliche Bedienaussparungen oder Anzeigeaussparungen vorzusehen, wie dies bei einer Abdeckung der Blende 20 durch ein Metallblech der Fall wƤre. Insbesondere im Bedienbereich 22 kann aufgrund der geringen Dicke der metallischen und/oder der Druckschicht das Blendenmaterial als Dielektrikum fĆ¼r hinter der Blende angeordneten Sensoren des Stellelementes 221 oder der Auswahlelemente 223, 224, 225 dienen.Since the areas 21 and 22 are produced only by surface treatment, in particular by the application of thin layers on the front side 201 and / or the back 202 of the panel 20, it is not necessary to provide on the front side 201 additional operating recesses or display recesses, as in a Covering the aperture 20 by a metal sheet would be the case. Due to the small thickness of the metallic and / or the pressure layer, in particular in the operating region 22, the diaphragm material can serve as a dielectric for sensors of the actuating element 221 or of the selection elements 223, 224, 225 arranged behind the diaphragm.

Die Erfindung weist eine Reihe von Vorteilen auf. Zum einen besitzt die Dunstabzugshaube im Bereich der Bedieneinheit einen einfachen Aufbau. Insbesondere kann die Frontseite des Sichtschirms durch eine durchgehende Platte gebildet werden, die lediglich an deren OberflƤche oder an deren OberflƤchen behandelt wurde. Zudem ist auch die Ausgestaltung der Auswahlelemente einfach realisierbar. Diese kƶnnen durch einfache NƤherungssensoren gebildet werden, die bei AnnƤherung des Fingers eines Bedieners aktiviert werden. Das Stellelement dient dann nach der Auswahl eines Betriebszustandes der Einstellung von Parametern des entsprechenden Betriebszustandes der Dunstabzugshaube. Es kƶnnen somit durch das Stellelement Einstellungen fĆ¼r unterschiedliche BetriebszustƤnde vorgenommen werden. Die eingestellten Parameter werden im Anzeigebereich des Informationsausgabebereiches angezeigt.The invention has a number of advantages. On the one hand, the extractor hood has a simple structure in the area of the operating unit. In particular, the front side of the viewing screen can be formed by a continuous plate which has been treated only on its surface or on its surfaces. In addition, the design of the selection elements is easy to implement. These can be formed by simple proximity sensors, which are activated when approaching the finger of an operator. The actuator is then after the selection of an operating state of the setting of parameters of the corresponding operating state of the hood. It can thus be made by the actuator settings for different operating conditions. The set parameters are displayed in the display area of the information output area.
