Description
Die vorliegende Erfindung betrifft eine Dunstabzugshaube mit einem entnehmbaren Filterelement.The present invention relates to an extractor hood with a removable filter element.
Bei Dunstabzugshauben in Küchen werden Filterelemente verwendet, um aus Dünsten und Wrasen, die durch die Dunstabzugshaube angesaugt werden, Verunreinigungen insbesondere Fett auszufiltern. Um eine möglichst hohe Abscheiderate der Dunstabzugshaube zu erzielen, muss die Fläche der Filterelemente möglichst groß sein. Zusätzlich werden Dunstabzugshauben in der Regel aber auch dazu genutzt einen unterhalb der Dunstabzugshaube befindlichen Herd und/oder eine Arbeitsfläche zu beleuchten. Für die Beleuchtungseinrichtungen wird in der Regel eine sogenannte Beleuchtungsblende in der Unterseite der Dunstabzugshaube vorgesehen. In oder auf dieser Beleuchtungsblende sind die Beleuchtungsvorrichtungen, insbesondere Lampen oder Leuchten angeordnet. Die Beleuchtungsblenden bestehen aus einem Blech, in dem Durchlässe für die Beleuchtungsvorrichtungen vorgesehen sind. Auch weitere Elemente, wie beispielsweise Sensoren können an diesen Beleuchtungsblenden vorgesehen sein.Filter elements are used in extractor hoods in kitchens in order to filter out impurities, in particular fat, from fumes and vapors that are sucked in through the extractor hood. In order to achieve the highest possible separation rate of the extractor hood, the surface of the filter elements must be as large as possible. In addition, extractor hoods are usually also used to illuminate a cooker and/or a work surface located below the extractor hood. For the lighting devices, a so-called lighting screen is usually provided in the underside of the extractor hood. The lighting devices, in particular lamps or lights, are arranged in or on this lighting screen. The lighting screens consist of a metal sheet in which openings for the lighting devices are provided. Other elements, such as sensors, can also be provided on these lighting screens.
Ein Nachteil der bekannten Dunstabzugshauben besteht somit darin, dass die Fläche, die zum Ausfiltern der Verunreinigungen aus der Luft zur Verfügung steht, durch die Beleuchtungsblenden verringert ist.A disadvantage of the known extractor hoods is that the area available for filtering out the impurities from the air is reduced by the lighting screens.

Die Aufgabe der vorliegenden Erfindung ist es somit eine Dunstabzugshaube zu schaffen, bei der zum einen die Filterfläche möglichst groß ausgelegt werden kann und die Dunstabzugshaube dennoch Zusatzfunktionen, wie erfindungsgemäß die Beleuchtung von darunter liegenden Flächen oder beispielsweise die Verwendung von Sensoren erfüllen kannThe object of the present invention is therefore to create an extractor hood in which, on the one hand, the filter surface can be designed as large as possible and the extractor hood can still fulfill additional functions, such as the illumination of underlying surfaces or, for example, the use of sensors
Der Erfindung liegt die Erkenntnis zugrunde, dass diese Aufgabe gelöst werden kann, indem zumindest ein Teil der für die Zusatzfunktionen erforderlichen Bauteile in dem Filterelement integriert wird.The invention is based on the finding that this object can be achieved by integrating at least some of the components required for the additional functions in the filter element.
Die Aufgabe wird daher gelöst durch eine Dunstabzugshaube, die ein Gehäuse und zumindest ein lösbar an dem Gehäuse befestigbares Filterelement umfasst, wobei die Dunstabzugshaube eine induktive Übertragungsvorrichtung aufweist und das Filterelement mindestens einen elektrischen Verbraucher aufweist, eine Primärspule der Übertragungsvorrichtung an dem Gehäuse der Dunstabzugshaube und eine Sekundärspule an dem Filterelement angeordnet ist und die Sekundärspule mit dem mindestens einen elektrischen Verbraucher verbunden ist. Die Dunstabzugshaube ist dadurch gekennzeichnet, dass das mindestens eine Filterelement eine Filterkassette ist, die als Filtermedium Streckmetalllagen aufweist und zumindest ein elektrischer Verbraucher eine Beleuchtungsvorrichtung ist, die in dem Filterelement aufgenommen ist und zur Beleuchtung von unterhalb der Dunstabzugshaube liegenden Flächen dient.The object is therefore achieved by an extractor hood which comprises a housing and at least one filter element which can be detachably fastened to the housing, the Extractor hood has an inductive transmission device and the filter element has at least one electrical consumer, a primary coil of the transmission device is arranged on the housing of the extractor hood and a secondary coil on the filter element and the secondary coil is connected to the at least one electrical consumer. The extractor hood is characterized in that the at least one filter element is a filter cassette which has layers of expanded metal as the filter medium and at least one electrical consumer is a lighting device which is accommodated in the filter element and is used to illuminate surfaces located below the extractor hood.
Das Gehäuse der Dunstabzugshaube kann auch als Sichthaube bezeichnet werden. Das Gehäuse stellt den Teil der Dunstabzugshaube dar, an dem das mindestens eine Filterelement lösbar befestigt ist. Als lösbare Befestigung wird eine Befestigung bezeichnet, die ohne Werkzeug gelöst werden kann. Das Filterelement kann beispielsweise an dem Gehäuse mittels Rastmittel, Klemmmitteln oder dergleichen lösbar befestigt sein. Vorzugsweise weist die Dunstabzugshaube mehrere Filterelemente auf. Im Folgenden wird der Einfachheit halber aber vorwiegend auf ein Filterelement Bezug genommen. Sind mehrere Filterelemente vorgesehen, so können diese alle gleich ausgestaltet sein. Es liegt aber auch im Rahmen der Erfindung, dass die Filterelemente unterschiedlich ausgeführt sind. Das Filterelement stellt erfindungsgemäß eine Filterkassette dar, die als Filtermedium beispielsweise Streckmetalllagen aufweisen kann.The housing of the extractor hood can also be referred to as a viewing hood. The housing represents the part of the extractor hood to which the at least one filter element is detachably attached. A detachable attachment is an attachment that can be released without tools. The filter element can, for example, be detachably fastened to the housing by means of latching means, clamping means or the like. The extractor hood preferably has a plurality of filter elements. For the sake of simplicity, however, reference is primarily made below to a filter element. If several filter elements are provided, they can all be designed in the same way. However, it is also within the scope of the invention for the filter elements to be designed differently. According to the invention, the filter element represents a filter cassette which, for example, can have layers of expanded metal as the filter medium.
Die Dunstabzugshaube weist mindestens eine induktive Übertragungsvorrichtung auf. Als induktive Übertragungsvorrichtung wird eine transformatorisch wirkende Übertragungsvorrichtung bezeichnet. Die Übertragungsvorrichtung stellt vorzugsweise einen Resonanzübertrager dar. Insbesondere weist die Übertragungsvorrichtung eine Primärspule und eine Sekundärspule auf. Die Primärspule ist hierbei an dem Gehäuse der Dunstabzugshaube und die Sekundärspule an dem Filterelement angeordnet. Die Spulen sind so angeordnet, dass im eingebauten Zustand des Filterelementes in dem Gehäuse der Dunstabzugshaube zwischen den Spulen ein Luftspalt besteht. Der Luftspalt ist gering und kann beispielsweise 4mm betragen. Wird an die Primärspule mit einer Spannung, beispielsweise einer Spannung normaler Netzfrequenz gespeist, wird ein elektromagnetisches Feld erzeugt. Im eingesetzten Zustand des Filterelementes liegt die Sekundärspule in einem geringen Abstand, dem Luftspalt, zu der Primärspule. Hierdurch werden die Spulen gekoppelt und das elektromagnetische Feld auf die Sekundärspule übertragen. Das Feld induziert dabei eine Spannung in der Sekundärspule.The extractor hood has at least one inductive transmission device. A transmission device that acts as a transformer is referred to as an inductive transmission device. The transmission device preferably represents a resonance transmitter. In particular, the transmission device has a primary coil and a secondary coil. The primary coil is arranged on the housing of the extractor hood and the secondary coil on the filter element. The coils are arranged in such a way that there is an air gap between the coils when the filter element is installed in the housing of the extractor hood. The air gap is small and can be 4mm, for example. If the primary coil is supplied with a voltage, for example a voltage of normal mains frequency, an electromagnetic field is generated. When the filter element is in place, the secondary coil is at a small distance, the air gap, from the primary coil. Through this the coils are coupled and the electromagnetic field is transferred to the secondary coil. The field induces a voltage in the secondary coil.
Die Primärspule dient somit zur Versorgung und kann beispielsweise bei einem Gleichstrom von 24V, der an diese angelegt wird, je nach Luftspalt 0,5A bis 0,55A liefern. Am Ausgang der Sekundärspule kann der Strom beispielsweise auf 1,3 A eingestellt werden. Je nach der Größe des Luftspaltes und der Last liegen am Eingang eines der Sekundärspule nachgeschalteten Treibers beispielsweise 9 bis 15V an. Die Primärspule und Sekundärspule weisen vorzugsweise Ferritkerne mit Windungen einer Hochfrequenzlitze auf. Beispielsweise kann die Primärspule wie folgt aufgebaut sein: 15 Windungen HF-Litze 90*0,071, 3 E-Kerne, Reihenresonanz. Die Sekundärspule kann beispielsweise wie folgt aufgebaut sein: 8 Windungen HF-Litze 180*0,071, 3 E-Kerne, Parallelresonanz. Ein solcher Aufbau kann eine Arbeitsfrequenz von 95 kHz und einen Wirkungsgrad (einschließlich eines nachgeschalteten Treibers, insbesondere LED-Treibers) von etwa 70-75% je nach Luftspalt und Last haben. Die Erfindung ist aber nicht auf diesen Aufbau beschränkt.The primary coil is therefore used for supply and can, for example, supply 0.5A to 0.55A with a direct current of 24V that is applied to it, depending on the air gap. At the output of the secondary coil, the current can be set to 1.3 A, for example. Depending on the size of the air gap and the load, 9 to 15V, for example, are present at the input of a driver connected downstream of the secondary coil. The primary coil and secondary coil preferably have ferrite cores with turns of a high-frequency stranded wire. For example, the primary coil can be constructed as follows: 15 turns of HF stranded wire 90*0.071, 3 E cores, series resonance. The secondary coil can be constructed as follows, for example: 8 windings of HF stranded wire 180*0.071, 3 E cores, parallel resonance. Such a setup can have an operating frequency of 95 kHz and an efficiency (including a downstream driver, especially LED driver) of around 70-75% depending on the air gap and load. However, the invention is not limited to this structure.
Durch das Bereitstellen einer solchen induktiven Übertragungsvorrichtung wird es möglich Energie und/oder Daten von dem Gehäuse der Dunstabzugshaube, insbesondere von weiteren Komponenten, die in dem Gehäuse aufgenommen oder an diesem angeordnet sind, an das Filterelement und insbesondere zu und von dem mindestens einen elektrischen Verbraucher zu übertragen. Die Übertragung erfolgt bei der erfindungsgemäßen Übertragungsvorrichtung kontaktfrei. Dies bringt den Vorteil mit sich, dass die Dunstabzugshaube besonders sicher handhabbar ist. Bei mechanischen Kontakten, wie Steckkontakten oder Schleifkontakten besteht nämlich die Gefahr, dass der Benutzer mit diesen Kontakten in Berührung kommt. Bei der erfindungsgemäßen Übertragungsvorrichtung hingegen erfolgt die Übertragung zwischen den Spulen, und bei einem aus der Dunstabzugshaube entnommenen Filterelement ist die darin vorgesehen Sekundärspule nicht stromführend und stellt somit keine Gefahr für den Benutzer dar. Zudem verschmutzen mechanische Kontakte beim Gebrauch der Dunstabzugshaube und deren Funktion kann daher nach einer gewissen Betriebsdauer nicht mehr gegeben sein. Da bei der erfindungsgemäßen Dunstabzugshaube keine mechanischen Kontakte zur Energie und/oder Datenübertragung notwendig sind, ist daher die zuverlässige Funktion der Übertragung auch nach längerem Betrieb gewährleistet.The provision of such an inductive transmission device makes it possible to transmit energy and/or data from the housing of the extractor hood, in particular from other components that are accommodated in or arranged on the housing, to the filter element and in particular to and from the at least one electrical consumer transferred to. In the case of the transmission device according to the invention, the transmission takes place without contact. This has the advantage that the extractor hood is particularly safe to handle. In the case of mechanical contacts, such as plug contacts or sliding contacts, there is a risk that the user will come into contact with these contacts. With the transmission device according to the invention, however, the transmission takes place between the coils, and when the filter element is removed from the extractor hood, the secondary coil provided therein is not live and therefore does not pose a risk to the user. In addition, mechanical contacts get dirty when the extractor hood is used and its function can therefore no longer be given after a certain period of operation. Since no mechanical contacts are required for energy and/or data transmission in the extractor hood according to the invention, the reliable functioning of the transmission is therefore guaranteed even after prolonged operation.
Zudem ist ein Vorsehen einer Energiequelle in dem Filterelement nicht notwendig, da eine an dem Filterelement erforderliche Energie durch die Übertragungsvorrichtung geliefert wird. Damit kann beispielsweise auf das Einsetzen von Batterien in das Filterelement verzichtet werden.In addition, it is not necessary to provide an energy source in the filter element, since energy required at the filter element is supplied by the transmission device. This means, for example, that batteries do not have to be inserted into the filter element.
Erfindungsgemäß stellt der elektrische Verbraucher eine Beleuchtungsvorrichtung dar.According to the invention, the electrical consumer is a lighting device.
Die Beleuchtungsvorrichtung umfasst zumindest eine Lichtquelle. Die Lichtquelle kann vorzugsweise eine LED darstellen. Zusätzlich zu der mindestens einen Lichtquelle kann die Beleuchtungsvorrichtung weitere Komponenten, wie beispielsweise eine Dimm-Einheit aufweisen. Diese Ausführungsform weist den Vorteil auf, dass auf einfache Weise das Design der Dunstabzugshaube verändert werden kann. Beispielsweise können durch den Benutzer unterschiedliche Filterelemente mit unterschiedlichen Farben eingesetzt werden. Statt LEDs können beispielsweise auch Halogenleuchten verwendet werden. Wegen des vergleichsweise geringen Wirkungsgrades und eventuell hoher Spannung dieser Leuchten ist diese Ausführungsform aber nicht bevorzugt. Im Fehlerfall ist ein Filterelement mit LED einfach durch den Benutzer der Dunstabzugshaube austauschbar.The lighting device comprises at least one light source. The light source can preferably be an LED. In addition to the at least one light source, the lighting device can have other components, such as a dimming unit. This embodiment has the advantage that the design of the extractor hood can be changed in a simple manner. For example, different filter elements with different colors can be used by the user. Halogen lights can also be used instead of LEDs, for example. Because of the comparatively low efficiency and possibly high voltage of these lights, however, this embodiment is not preferred. In the event of a fault, a filter element with LED can be easily replaced by the extractor hood user.
Zusätzlich kann zumindest ein elektrischer Verbraucher einen Sensor umfassen. Hierdurch wird es möglich Sensorik in das Filterelement zu integrieren. Der Sensor oder weitere Teile der Sensorik können durch die Übertragungsvorrichtung mit Strom versorgt werden. Zusätzlich oder alternativ können aber durch die Übertragungsvorrichtung auch Daten an die Sensorik übertragen werden. Schließlich ist es auch möglich, Daten von der Sensorik über die Übertragungsvorrichtung an das Gehäuse der Dunstabzugshaube und insbesondere an Komponenten in dem Gehäuse der Dunstabzugshaube, wie beispielsweise ein Steuergerät zu übermitteln. Die Sensorik kann beispielsweise zur Steuerung der Dunstabzugshaube oder zur Überwachung eines unterhalb der Dunstabzugshaube angeordneten Kochfeldes dienen. Zudem kann eine Sensorik auch zur Erkennung der Filterbelegung, das heißt der Filtersättigung dienen.In addition, at least one electrical consumer can include a sensor. This makes it possible to integrate sensors into the filter element. The sensor or other parts of the sensor system can be supplied with power by the transmission device. In addition or as an alternative, however, data can also be transmitted to the sensor system by the transmission device. Finally, it is also possible to transmit data from the sensors via the transmission device to the housing of the extractor hood and in particular to components in the housing of the extractor hood, such as a control unit. The sensor system can be used, for example, to control the extractor hood or to monitor a hob arranged below the extractor hood. In addition, a sensor system can also be used to detect the filter occupancy, ie the filter saturation.
Zusätzlich kann zumindest ein elektrischer Verbraucher eine Anzeigeeinheit sein. Die Anzeigeeinheit kann auch als Display bezeichnet werden. Bei dieser Ausführungsform vereinfacht sich der Aufbau der Dunstabzugshaube weiter. Insbesondere bei sogenannten Vertikalessen oder Schrägessen, bei denen die Unterseite der Filterelemente für den Benutzer sichtbar ist, können dem Benutzer über die Anzeigeeinheit in dem Filterelement Informationen angezeigt werden, wie beispielsweise der eingestellte Betriebszustand der Dunstabzugshaube.In addition, at least one electrical consumer can be a display unit. The display unit can also be referred to as a display. In this embodiment, the structure of the extractor hood is further simplified. Particularly in the case of so-called vertical hoods or inclined hoods, in which the underside of the filter elements is visible to the user, information can be displayed to the user via the display unit in the filter element, such as the set operating status of the extractor hood.
Zusätzlich kann zumindest ein elektrischer Verbraucher eine Bedieneinheit sein. Auch bei dieser Ausführungsform vereinfacht sich der Aufbau der Dunstabzugshaube weiter. Insbesondere bei sogenannten Vertikalessen oder Schrägessen, bei denen die Unterseite der Filterelemente für den Benutzer sichtbar ist, kann die Bedieneinheit, die in dem Filterelement aufgenommen ist, auf einfache Weise vom Benutzer erreicht werden. Das Vorsehen einer separaten Bedieneinheit an der Außenseite der Dunstabzugshaube, wie dies in der Regel im Stand der Technik verwendet werden, kann entfallen.In addition, at least one electrical consumer can be an operating unit. In this embodiment, too, the structure of the extractor hood is further simplified. In particular in the case of so-called vertical or sloping hoods, in which the underside of the filter elements is visible to the user, the user can easily reach the operating unit, which is accommodated in the filter element. The provision of a separate operating unit on the outside of the extractor hood, as is generally used in the prior art, can be omitted.
Gemäß einer bevorzugten Ausführungsform ist die Leistungskopplung der Übertragungsvorrichtung, das heißt zwischen der Primärspule und der Sekundärspule nur im eingebauten Zustand des Filterelementes vorhanden. Hierdurch kann auf einfache Weise der korrekte Einbau des Filterelementes überprüft werden. Erfindungsgemäß sind in dem Filterelement Beleuchtungselemente aufgenommen, die durch die Übertragungsvorrichtung mit Energie versorgt werden. Somit kann der Benutzer durch Ausbleiben der Beleuchtung darüber informiert werden, dass das Filterelement nicht korrekt in der Dunstabzugshaube aufgenommen ist.According to a preferred embodiment, the power coupling of the transmission device, ie between the primary coil and the secondary coil, is only present when the filter element is installed. In this way, the correct installation of the filter element can be checked in a simple manner. According to the invention, lighting elements that are supplied with energy by the transmission device are accommodated in the filter element. The user can thus be informed that the filter element is not correctly accommodated in the extractor hood by the absence of the lighting.
Gemäß einer bevorzugten Ausführungsform ist die induktive Übertragungsvorrichtung eine Übertragungsvorrichtung zur Übertragung von Energie zu dem Filterelement und zur Übertragung von Daten von der Primärspule zu der Sekundärspule, von der Sekundärspule zu der Primärspule oder zur bidirektionalen Übertragung von Daten zwischen der Primärspule und der Sekundärspule ausgelegt ist ausgelegt ist.According to a preferred embodiment, the inductive transmission device is a transmission device for transmitting energy to the filter element and for transmitting data from the primary coil to the secondary coil, from the secondary coil to the primary coil or for the bidirectional transmission of data between the primary coil and the secondary coil is.
Gemäß einer Ausführungsform weist die Dunstabzugshaube ausschließlich an dem mindestens einen Filterelement eine Beleuchtungsvorrichtung auf. Bei dieser Ausführungsform wird es möglich, auf Beleuchtungsblenden an der Dunstabzugshaube zu verzichten und alle Beleuchtungsvorrichtungen an den Filterelementen vorzusehen. Der so eingesparte Platz kann durch weitere Filterelemente oder durch Verwendung größerer Filterelemente als Filterfläche genutzt werden und damit die Effizienz der Dunstabzugshaube gesteigert werden.According to one embodiment, the extractor hood has a lighting device exclusively on the at least one filter element. With this embodiment, it is possible to dispense with lighting screens on the extractor hood and to provide all lighting devices on the filter elements. The space saved in this way can be replaced by additional filter elements or by using larger filter elements can be used as a filter surface, thus increasing the efficiency of the extractor hood.
Gemäß einer Ausführungsform weist die Übertragungsvorrichtung eine Primärseite und eine Sekundärseite auf, in der Primärseite liegt die Primärspule vor und in der Sekundarseite liegen die Sekundärspule und ein Treiber für einen elektrischen Verbraucher vor.According to one embodiment, the transmission device has a primary side and a secondary side, the primary coil is present in the primary side and the secondary coil and a driver for an electrical load are present in the secondary side.
Vorzugsweise sind die Übertragungsvorrichtung und der mindestens eine elektrische Verbraucher in der Filtereinheit wasserfest ausgeführt. Beispielsweise kann die Übertragungsvorrichtung in wasserabweisendes Material eingegossen sein oder in einem wasserdichten Gehäuse in der Filtereinheit aufgenommen sein. Auch die elektrischen Verbraucher, beispielsweise LEDs, können jeweils in ein wasserdichtes Gehäuse aufgenommen sein. Durch diese Ausgestaltung wird es möglich, das Filterelement in der Spülmaschine zu reinigen ohne die Übertragungsvorrichtung und den mindestens einen elektrischen Verbraucher zu beschädigen.The transmission device and the at least one electrical consumer in the filter unit are preferably designed to be waterproof. For example, the transmission device can be cast in water-repellent material or housed in a waterproof housing in the filter unit. The electrical consumers, such as LEDs, can each be accommodated in a watertight housing. This configuration makes it possible to clean the filter element in the dishwasher without damaging the transmission device and the at least one electrical consumer.

Die Erfindung ist nicht auf die in den Figuren gezeigten Ausführungsformen beschränkt. Vielmehr können auch andere Bauarten einer induktiven Übertragungsvorrichtung zur Übertragung von Energie und / oder Daten verwendet werden. Zusätzlich zu der gezeigten Beleuchtungsvorrichtung können erfindungsgemäß in dem Filterelement weitere elektrische Verbraucher, beispielsweise Elektronik, Sensorik, ein Display oder eine Bedieneinheit betrieben werden. Auch diese Verbraucher werden, wie die gezeigte Beleuchtungsvorrichtung zuverlässig mit der notwendigen Betriebsenergie versorgt. Zudem können die Beleuchtungsvorrichtung und / oder weitere elektrische Verbraucher in dem Filterelement von anderen Elektroniken in der Dunstabzugshaube mit Daten versorgt werden, die beispielsweise die notwendigen Steuerinformationen für den Verbraucher enthalten. Schließlich können die Verbraucher in dem Filterelement an andere Elektroniken in der Dunstabzugshaube Daten senden, die zum zweckmäßigen Betrieb der Dunstabzugshaube notwendig sind. Beispielsweise können Sensorsignale oder Bedieneingaben übertragen werden.The invention is not limited to the embodiments shown in the figures. Rather, other designs of an inductive transmission device can also be used to transmit energy and/or data. In addition to the lighting device shown, further electrical loads, for example electronics, sensors, a display or an operating unit, can be operated in the filter element according to the invention. Like the lighting device shown, these consumers are also reliably supplied with the necessary operating energy. In addition, the lighting device and/or other electrical loads in the filter element can be supplied with data from other electronics in the extractor hood, which data contains, for example, the necessary control information for the load. Finally, the consumers in the filter element can send data to other electronics in the extractor hood that are necessary for the appropriate operation of the extractor hood. For example, sensor signals or operator inputs can be transmitted.
Mit der vorliegenden Erfindung wird ein elektrischer Verbraucher im Filterelement einer Dunstabzugshaube an weitere, in die Dunstabzugshaube selbst montierte elektronische Einheiten angebunden, wobei über diese Anbindung Energie und vorzugsweise bidirektional Daten transportiert werden können.With the present invention, an electrical consumer in the filter element of a fume hood is connected to other electronic units mounted in the fume hood itself, with energy and preferably bidirectional data being able to be transported via this connection.
Die vorliegende Erfindung weist eine Reihe von Vorteilen auf. Insbesondere ist, wenn im Filterelement einer Dunstabzugshaube elektrische Verbraucher (Elektronik, Sensorik, Beleuchtung, Display...) betrieben werden sollen, die bisher bekannte Verwendung einer Batterie oder von Schleif- beziehungsweise Steckkontakten zur Versorgung mit der notwendigen Betriebsenergie nicht mehr notwendig. Hierdurch werden zum einen die Handhabung der Dunstabzugshaube und zum anderen die Sicherheit erhöht. Die Betriebssicherheit der gesamten Dunstabzugshaube wird damit massiv erhöht. Die Primärelektronik in der Dunstabzugshaube ist systembedingt vollständig erdfrei und erfüllt alle Sicherheitsanforderungen.The present invention has a number of advantages. In particular, if electrical consumers (electronics, sensors, lighting, display...) are to be operated in the filter element of an extractor hood, the previously known use of a Batteries or sliding or plug contacts for supplying the necessary operating energy are no longer necessary. As a result, on the one hand the handling of the extractor hood and on the other hand the safety are increased. The operational safety of the entire extractor hood is thus massively increased. The primary electronics in the extractor hood are completely unearthed due to the system and meet all safety requirements.
Zudem können jederzeit durch das schlichte Austauschen der Filterelemente neue Designvarianten erzeugt werden. Zum Beispiel können verschiedene Arten von Beleuchtungen verwendet werden. Beispielsweise mit und ohne Dimmer. Zudem können durch Austausch der Filterelemente Funktionsvarianten der Dunstabzugshaube erzeugt werden (mit/ohne Sensorik), verschiedene Arten von Sensorik zur Steuerung der Dunstabzugshaube oder zur Überwachung des Kochfeldes und dergleichen.In addition, new design variants can be created at any time by simply exchanging the filter elements. For example, different types of lighting can be used. For example with and without a dimmer. In addition, functional variants of the extractor hood can be created by replacing the filter elements (with/without sensors), different types of sensors for controlling the extractor hood or for monitoring the hob and the like.
Die Montage, das heißt das Einsetzen der Filterelemente in das Gehäuse der Dunstabzugshaube durch den Kunden bleibt unverändert einfach. Damit können Gerätevarianten, wie beispielsweise unterschiedliche Anzahl / Art / Position von Beleuchtungsvorrichtungen sehr schnell dargestellt werden. Die Optimierung einer induktiven Energie- und Datenübertragung ist einfach. Eine Geräteentwicklung ist nicht schwer. Eine einfachste Übertragungsvorrichtung kann beispielsweise 10W übertragen und weist eine langsame Datenübertragung auf. Je nach elektrischem Verbraucher in dem Filter kann dies aber ausreichend sein.The assembly, ie the insertion of the filter elements into the housing of the extractor hood by the customer, remains as easy as ever. Device variants, such as a different number/type/position of lighting devices, can thus be displayed very quickly. Optimizing inductive energy and data transmission is easy. Device development is not difficult. For example, a simple transmission device can transmit 10W and has a slow data transmission. However, depending on the electrical consumer in the filter, this may be sufficient.
Mit der vorliegenden Erfindung kann sehr einfach und jederzeit eine Datenübertragung dargestellt werden, die Daten aus der Dunstabzugshaube in das Filterelement beziehungsweise aus dem Filterelement in die Dunstabzugshaube überträgt.With the present invention, data transmission can be implemented very easily and at any time, which transmits data from the extractor hood to the filter element or from the filter element to the extractor hood.
Zudem wird beispielsweise durch den Einbau von Beleuchtungsvorrichtungen, wie beispielsweise LED in das Filterelement die für die Filterelemente verfügbare Fläche an der Unterseite der Dunstabzugshaube größer und die Beleuchtungsvorrichtungen können in dem Filterelement frei positioniert werden.In addition, for example, by installing lighting devices such as LEDs in the filter element, the area available for the filter elements on the underside of the extractor hood becomes larger and the lighting devices can be freely positioned in the filter element.
