The grease filter is made of plastic. According to the invention, at least one light source is arranged downstream of the grease filter in the flow direction.

Description

Die vorliegende Erfindung betrifft eine Dunstabzugshaube mit hinterleuchtetem Fettfilter.The present invention relates to an extractor hood with backlit grease filter.

Bei Dunstabzugshauben werden Filtereinheiten, insbesondere Filterkassetten, verwendet, um aus dem Wrasen, der durch die Dunstabzugshaube angesaugt wird, Verunreinigungen, insbesondere Fettpartikel abzuscheiden. Diese Filtereinheiten werden daher auch als Fettfilter bezeichnet.In extractor hoods filter units, in particular filter cassettes, are used to remove impurities, in particular fat particles, from the vapor which is sucked in by the extractor hood. These filter units are therefore also referred to as a grease filter.

Im Stand der Technik sind Streckmetallfilter bekannt, welche in mehreren Lagen hintereinander angeordnet sind. Die EP 3 216 508 offenbart eine Filtereinheit für eine Dunstabzugshaube, die zumindest eine Filterlage aus einem Kunststoffmaterial aufweist.Expanded metal filters are known in the prior art, which are arranged in several layers one behind the other. The EP 3 216 508 discloses a filter unit for an extractor hood, which has at least one filter layer of a plastic material.

Weiterhin sind bei Dunstabzugshauben in der Regel Leuchten vorgesehen, welche zur Beleuchtung einer unterhalb der Dunstabzugshaube vorgesehenen Arbeitsumgebung eingerichtet sind. Die Arbeitsumgebung ist in der Regel das unter der Dunstabzugshaube angeordnete Kochfeld. Im Stand der Technik sind die Leuchten und die Filtereinheiten einer Dunsthaube voneinander getrennte Komponenten. Meist werden zur Beleuchtung im Stand der Technik neben der Filtereinheit und am Rand der Haube eingebaute Leuchtmodule vorgesehen.Furthermore, in the case of extractor hoods, lights are generally provided which are set up to illuminate a working environment provided underneath the extractor hood. The working environment is usually the hob located under the cooker hood. In the prior art, the lights and the filter units of a cooker hood are separate components. In most cases, lighting modules in the state of the art are provided in addition to the filter unit and on the edge of the hood.

Bei bisherigen Lösungen ist daher immer die untere Fläche der Dunstabzugshaube zwischen Filterfläche und Beleuchtung aufzuteilen. Dies ist zwangsläufig eine Kompromisslösung, da für eine gute Filter- und Beleuchtungsleistung die jeweilige Fläche möglichst groß sein sollte.In previous solutions, therefore, always the lower surface of the hood between filter surface and lighting is divided. This is inevitably a compromise solution, since for a good filtering and lighting performance, the respective area should be as large as possible.

Aufgabe der vorliegenden Erfindung ist es eine alternative Anordnung der beiden Funktionsträger Beleuchtung und Filter in Dunstabzugshauben zu finden. Insbesondere soll eine Dunstabzugshaube bereitgestellt werden, bei der die zur Verfügung stehende Fläche optimal genutzt wird.Object of the present invention is to find an alternative arrangement of the two function carrier lighting and filters in cooker hoods. In particular, an extractor hood is to be provided in which the available area is optimally utilized.

Die Aufgabe wird gelöst durch eine Dunstabzugshaube mit den Merkmalen des Patentanspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.The object is achieved by an extractor hood with the features of claim 1. Advantageous developments of the invention are specified in the dependent claims.

Die Erfindung geht aus von einer Dunstabzugshaube, mit einem Dunstabzugsgehäuse, das eine Absaugöffnung aufweist, einem in dem Dunstabzugsgehäuse aufgenommenen Gebläse und einer in Strömungsrichtung zumindest teilweise vor der Absaugöffnung angeordneten Filtereinheit zur Reinigung der durch das Gebläse angesaugten Luft. Die Filtereinheit weist eine Filtermatte mit zumindest einer Filterlage auf, die aus einem Kunststoffmaterial besteht und Öffnungen aufweist, deren Größe fixiert ist.The invention relates to an extractor hood, with a fume hood housing, which has a suction opening, a blower accommodated in the fume hood housing and a filter unit arranged in the flow direction at least partially in front of the suction opening for cleaning the air sucked in by the blower. The filter unit has a filter mat with at least one filter layer, which consists of a plastic material and has openings whose size is fixed.

Erfindungsgemäß ist in Strömungsrichtung hinter der Filtereinheit zumindest ein Leuchtmittel angeordnet. Das mindestens eine Leuchtmittel ist derart ausgerichtet, dass eine Hauptausbreitungsrichtung des ausgestrahlten Lichts des Leuchtmittels derart in Richtung der Filtereinheit orientiert ist, dass das ausgestrahlte Licht von der Filtermatte auf eine unter der Dunstabzugshaube vorgesehene Arbeitsumgebung gestreut wird.According to the invention, at least one light source is arranged downstream of the filter unit in the flow direction. The at least one luminous means is oriented such that a main propagation direction of the emitted light of the luminous means is oriented in the direction of the filter unit such that the emitted light is scattered by the filter mat onto a working environment provided under the extractor hood.

Als "Kunststoffmaterial" wird im Sinne der Erfindung geformter Kunststoff bezeichnet. Kunststoff ist aus Werkstoffen ausgebildet, die hauptsächlich aus Makromolekülen bestehen. Die jeweiligen Makromoleküle eines Kunststoffes sind Polymere und daher aus sich wiederholenden Grundeinheiten aufgebaut. Die Polymere können aus Naturstoffen oder rein synthetisch sein. Beispielsweise kann als Kunststoffmaterial Polyester, Polypropylen oder ähnliches verwendet werden. Die Filterlage weist Öffnungen auf, die in ihrer Größe fixiert sind. Als "Öffnung" wird die Durchlassöffnung beziehungsweise der Zwischenraum zwischen Filterstegen, die aus Kunststoffmaterial bestehen, in der jeweiligen Filterlage bezeichnet. Die Filterstege werden im Folgenden auch als Stege bezeichnet. Die Öffnungen bestimmen sich durch den Filterstegabstand. Im Sinne der Erfindung werden die Öffnungen auch als Löcher oder Maschen bezeichnet. Durch die Öffnungen in der Filterlage kann der anströmende Wrasen hindurch strömen. Als Öffnungen, die in ihrer Größe fixiert sind, werden Öffnungen bezeichnet, die in ihrer Größe nicht veränderbar sind, das heißt die Filterstege zwischen den Öffnungen können nicht verschoben werden. Somit weisen die Öffnungen einer Filterlage dauerhaft die gleiche Größe auf und die Größe der Öffnungen wird bei der Herstellung einer Filterlage vorbestimmt. Vorzugsweise sind die Öffnungen einer Filterlage gleich groß. Besonders bevorzugt sind die Öffnungen der Filterlage fein beziehungsweise klein gegenüber den Maschen aus dem Stand der Technik bekannten Streckmetalllagen. Das "Leuchtmittel" ist zum Emittieren sichtbaren Lichts vorgesehen. Das Leuchtmittel der Beleuchtungsvorrichtung kann beispielsweise eine LED (light emitting diode), eine Glühlampe oder ein Halogenstrahler sein. "Hauptausbreitungsrichtung" meint bei Leuchtmitteln mit einer Richtcharakteristik, also einer winkelabhängigen Lichtstärke, die Richtung, in der das Leuchtmittel prozentual gesehen die höchste Lichtstärke abstrahlt.As "plastic material" referred to in the context of the invention molded plastic. Plastic is made of materials that consist mainly of macromolecules. The respective macromolecules of a plastic are polymers and therefore composed of repeating basic units. The polymers may be natural or purely synthetic. For example, as the plastic material, polyester, polypropylene or the like can be used. The filter layer has openings which are fixed in size. As an "opening", the passage opening or the intermediate space between filter webs, which consist of plastic material, referred to in the respective filter layer. The filter webs are also referred to below as webs. The openings are determined by the distance between the filter bars. For the purposes of the invention, the openings are also referred to as holes or meshes. The inflowing vapor can flow through the openings in the filter layer. As openings which are fixed in size, openings are referred to, which are not changeable in size, that is, the filter webs between the openings can not be moved. Thus, the openings of a filter layer permanently have the same size and the size of the openings is predetermined in the preparation of a filter layer. Preferably, the openings of a filter layer are the same size. Particularly preferably, the openings of the filter layer are fine or small compared to the meshes of the prior art known expanded metal layers. The "light source" is provided for emitting visible light. The bulbs of the Lighting device may be, for example, an LED (light emitting diode), an incandescent lamp or a halogen lamp. In the case of light sources having a directional characteristic, that is to say an angle-dependent light intensity, "main propagation direction" means the direction in which the illuminant radiates the highest intensity of light as a percentage.

In einer Ausführungsform ist das mindestens eine Leuchtmittel im Innenraum des Dunstabzugsgehäuses angeordnet. Bevorzugt ist das Leuchtmittel auf einer Ebene im Wesentlichen flächenparallel zur Filterfläche angeordnet.In one embodiment, the at least one lighting means is arranged in the interior of the extractor housing. Preferably, the lighting means is arranged on a plane substantially parallel to the surface of the filter surface.

Nach einer weiteren Ausgestaltung der Erfindung ist das Leuchtmittel seitlich versetzt von der Filterfläche und auf einer Ebene im Wesentlichen orthogonal zur Filterfläche angeordnet.According to a further embodiment of the invention, the lighting means is arranged laterally offset from the filter surface and on a plane substantially orthogonal to the filter surface.

Gemäß eines weiteren Aspekts der Erfindung ist das mindestens eine Leuchtmittel in die Filtereinheit integriert, und die Filtereinheit ist entnehmbar. Diese Einheit wird in der Dunstabzugshaube eingebaut und kann zur Reinigung entnommen werden. Besonders vorteilhaft sind in diesem Fall die Leuchtmittel gegenüber der Reinigung, zum Beispiel in einer Spülmaschine, beständig ausgeführt.According to a further aspect of the invention, the at least one lighting means is integrated in the filter unit, and the filter unit is removable. This unit is installed in the cooker hood and can be removed for cleaning. Particularly advantageous in this case, the bulbs compared to the cleaning, for example, in a dishwasher, running resistant.

Gemäß eines anderen Aspekts der Erfindung ist das Kunststoffmaterial zumindest teilweise lichtdurchlässig und/oder lichtstreuend.According to another aspect of the invention, the plastic material is at least partially translucent and / or light-scattering.

Gemäß einer Ausgestaltung der vorliegenden Erfindung ist eine Steuervorrichtung zur Einstellung des Leuchtmittels vorgesehen. Die Einstellung des Leuchtmittels umfasst eine Änderung einer Farbtemperatur, einer Lichtintensität, einer Richtung der Lichtausstrahlung, eines Ausleuchtungsbereichs und/oder einer Dauer einer Lichtausstrahlung.According to one embodiment of the present invention, a control device for adjusting the lighting means is provided. The adjustment of the luminous means comprises a change of a color temperature, a light intensity, a direction of the light emission, an illumination range and / or a duration of a light emission.

Im Sinne der Erfindung wird als Farbtemperatur ein Maß bezeichnet, um den jeweiligen Farbeindruck einer Lichtquelle zu bestimmen. Als Lichtintensität im Sinne der Erfindung wird die Stärke des Lichts bezeichnet. Die Intensität ist der Anteil der gesamten Lichtmenge, die von einer Lichtquelle in einer gegebenen Raumrichtung emittiert wird. Als Richtung der Lichtausgabe wird erfindungsgemäß die Wirkungsrichtung der Ausgabe des Lichtes einer Lichtquelle bezeichnet. Der Ausleuchtungsbereich ist erfindungsgemäß der Bereich in einem Raum oder einer Fläche der mittels des emittierenden Lichtes einer Lichtquelle ganz oder teilweise ausgeleuchtet bzw. angestrahlt wird. Die Dauer der Lichtausgabe kann die Ausgabedauer selber sowie gegebenenfalls einzuhaltende Intervalle zwischen den Ausgaben des Lichtes umfassen. Demnach kann die Ausgabe des Lichtes beispielsweise ein Blinksignal sein.For the purposes of the invention, a measure is referred to as color temperature in order to determine the respective color impression of a light source. Light intensity in the sense of the invention is the strength of the light. The intensity is the proportion of the total amount of light emitted by a light source in a given spatial direction. As the direction of the light output according to the invention the direction of action of the output of the light of a light source is called. The illumination range is according to the invention Area in a room or a surface which is completely or partially illuminated or illuminated by means of the emitting light of a light source. The duration of the light output may include the output duration itself as well as any intervals between the outputs of the light to be observed. Thus, the output of the light may be, for example, a blinking signal.

In einer Weiterbildung stellt die Steuervorrichtung das mindestens eine Leuchtmittel abhängig von einem Betriebszustand der Dunstabzugshaube ein. Ein Betriebszustand der Dunstabzugshaube ist beispielsweise "eingeschaltet", "ausgeschaltet" oder die eingestellte Leistungsstufe.In a further development, the control device adjusts the at least one light-emitting means as a function of an operating state of the extractor hood. An operating state of the extractor hood is, for example, "switched on", "switched off" or the set power level.

Gemäß einer weiteren Ausgestaltung ist in Strömungsrichtung vor der Filtermatte eine im Wesentlichen flächenparallel zur Filtermatte angeordnete Decklage vorgesehen, welche zumindest teilweise luftdurchlässig ist. Vorteilhaft ist die Decklage aus einem Metall gebildet.According to a further embodiment, in the flow direction in front of the filter mat, a cover layer arranged substantially parallel to the surface of the filter mat is provided which is at least partially permeable to air. Advantageously, the cover layer is formed from a metal.

Die Decklage kann sowohl gleichartig wie die übrigen Filterlagen aufgebaut sein, als auch optisch und funktional unterschiedlich sein. Zudem kann auch eine Decklage in Strömungsrichtung hinter der Filterlage angeordnet sein. Aufgabe der Decklage ist beispielsweise der mechanische Schutz der anfälligen Kunststofffilterinnenlagen und/oder die optische Aufwertung des Gesamtfilters. Die Decklage(n) soll(en) hierbei ausreichend luftdurchlässig sein, um einen geringen Druckverlust zu erreichen.The cover layer can be constructed as similar as the other filter layers, as well as visually and functionally different. In addition, a cover layer can be arranged downstream of the filter layer in the flow direction. The object of the cover layer is, for example, the mechanical protection of the prone plastic filter inner layers and / or the visual enhancement of the overall filter. The cover layer (s) should in this case be sufficiently permeable to air in order to achieve a low pressure loss.

Gemäß einer bevorzugten Ausgestaltung der vorliegenden Erfindung ist die Filtereinheit von einem umlaufenden Rahmen eingefasst. Auf diese Weise sind alle Filterlagen sicher über einen Rahmen eingefasst. Dies hat den Vorteil, dass das Filterelement leichter handhabbar ist, wenn es beispielsweise zur Reinigungszwecken aus der Dunstabzugshaube entnommen werden soll.According to a preferred embodiment of the present invention, the filter unit is enclosed by a peripheral frame. In this way, all filter layers are securely bordered by a frame. This has the advantage that the filter element is easier to handle, if it is to be removed, for example, for cleaning purposes of the hood.

Gemäß einer bevorzugten Ausführungsform des erfindungsgemäßen Filterelementes, besteht die zumindest eine Filterlage aus zumindest zwei Schichten und die Schichten sind jeweils aus Kunststoffprofilen ausgebildet. Als Schicht wird im Sinne der Erfindung ein Element bezeichnet, aus dem eine Filterlage zumindest teilweise ausgebildet ist und welche aus einem Kunststoffmaterial besteht. Gemäß einer Ausführungsform weist eine Filterlage zumindest zwei Schichten auf, die in der Filterlage aufeinander liegen, das heißt gestapelt sind und die nacheinander von anströmende Wrasen durchströmt werden. Die Schichten können vor dem Zusammenbau der Filterlage als separate Elemente vorliegen.According to a preferred embodiment of the filter element according to the invention, the at least one filter layer consists of at least two layers and the layers are each formed from plastic profiles. As a layer is referred to in the context of the invention, an element from which a filter layer is at least partially formed and which consists of a plastic material. According to one embodiment, a Filter layer on at least two layers, which lie on top of each other in the filter layer, that is stacked and are flowed through successively by incoming vapors. The layers may be present as separate elements prior to assembly of the filter layer.

Vorzugsweise sind die Schichten einer Filterlage aus Kunststoffprofilen gebildet. Im Sinne der Erfindung ist ein Profil ein langes dünnes Element, welches flexibel oder starr ist. Das Profil kann in seiner Länge abhängig von der Größe der zu verwendenden Schicht auf einfache Weise begrenzt werden. Der Querschnitt des Kunststoffprofils kann beispielweise kreisförmig, oval, flach oder vier- oder mehreckig sein. Eine Schicht einer Filterlage kann mehrere Kunststoffprofile aufweisen, das heißt, dass die Schicht nicht aus einem einzigen Kunststoffprofil bestehen muss.Preferably, the layers of a filter layer are formed from plastic profiles. For the purposes of the invention, a profile is a long, thin element which is flexible or rigid. The profile can be easily limited in length, depending on the size of the layer to be used. The cross section of the plastic profile may be, for example, circular, oval, flat or polygonal or polygonal. A layer of a filter layer may have a plurality of plastic profiles, that is, the layer does not have to consist of a single plastic profile.

Weiterhin ist eine Ausführungsform des erfindungsgemäßen Filterelementes bevorzugt, in der die Filterlage aus gewebtem oder geflochtenem Kunststoffmaterial besteht oder eine Kunststoffplatte mit eingebrachten Öffnungen darstellt. Bei den Ausführungsformen als gewebtem oder geflochtenem Kunststoffmaterial werden die Filterstege, die die als Maschen ausgebildeten Öffnungen begrenzen, durch Fäden gebildet. Bei der Ausführungsform als Kunststoffplatte werden die Filterstege durch das nach dem Einbringen der Löcher in die Kunststoffplatte verbleibenden Materialstreifen gebildet.

Figur 1 zeigt in einer schematischen Darstellung eine Filtereinheit mit integrierten Leuchtmitteln. Die Filterlagen 101 aus Kunststoff können in beliebiger Farbe ausgestaltet sein. Die Filterlagen 101 sind von einem Rahmen 102 und einer in Strömungsrichtung vor den Filterlagen 101 angeordneten Decklage 103 eingefasst. Die Decklage ist als metallische Designblende ausgestaltet, über deren Öffnungen in Form von breiten Schlitzen die angesaugte Luft in den Filter gelangt. Die Filtereinheit 101 ist derart in einem Dunstabzugsgehäuse 104 angebracht, dass die Filtereinheit durch einen Nutzer, beispielsweise zu Reinigungszwecken, leicht entnehmbar und wiedereinsetzbar ist. FIG. 1 shows a schematic representation of a filter unit with integrated bulbs. The filter layers 101 made of plastic can be configured in any color. The filter layers 101 are enclosed by a frame 102 and a cover layer 103 arranged in the flow direction in front of the filter layers 101. The cover layer is designed as a metallic design panel, through whose openings in the form of wide slots the sucked air enters the filter. The filter unit 101 is mounted in a fume hood 104 such that the filter unit is easily removable and re-insertable by a user, for example for cleaning purposes.

In dem Dunstabzugsgehäuse 104 sind in einer Ebene flächenparallel zur Filterfläche zwei Leuchtmodule 105 angebracht. Die Leuchtmittel sind zum Emittieren sichtbaren Lichts vorgesehen. Weiterhin ist eine nicht gezeigte Steuervorrichtung zur Einstellung der Leuchtmittel vorgesehen. Das Leuchtmittel kann beispielsweise eine LED (light emitting diode), eine Glühlampe oder ein Halogenstrahler sein. Das Leuchtmodul umfasst ferner mindestens eine Halterung für das Leuchtmittel und mindestens eine Kontaktstelle für die Anbindung des Leuchtmittels an die Steuervorrichtung, mittels welcher die Spannungsversorgung der Kontaktstelle eingestellt werden kann.In the extractor housing 104 two light modules 105 are mounted in a plane surface parallel to the filter surface. The bulbs are designed to emit visible light. Furthermore, a control device, not shown, for adjusting the lighting means is provided. The light source may be, for example, an LED (light emitting diode), an incandescent lamp or a halogen radiator. The lighting module further comprises at least one holder for the lighting means and at least one contact point for the connection of the lighting means to the control device, by means of which the voltage supply of the contact point can be adjusted.

Die mit Fettpartikeln versetzte Luft 106 wird durch einen nicht gezeigten Lüfter angesaugt und über die Öffnungen der Designblende 103 durch den Filter 101 geführt. Die dabei gereinigte Luft 107 wird innerhalb des Dunstabzugsgehäuses an den Leuchtmitteln vorbei zum Lüfter geführt. Das von den Leuchtmitteln 105 emittierte Licht 108 ist in Richtung der Filterfläche 101 orientiert und tritt durch diese hindurch. Dabei wird das Licht 108 in Richtung des unter der Dunstabzugshaube angeordneten Kochfeldes gestreut.The fat-displaced air 106 is sucked in by a fan, not shown, and passed through the openings of the design panel 103 through the filter 101. The case cleaned air 107 is passed inside the extractor housing on the bulbs to the fan. The light 108 emitted by the light sources 105 is oriented in the direction of the filter surface 101 and passes therethrough. In this case, the light 108 is scattered in the direction of the arranged under the hood cooktop.

Figur 2 zeigt in einer schematischen Darstellung eine Filtereinheit und im Dunstabzugsgehäuse seitlich angeordnete Leuchtmittel. Zur Vermeidung von Wiederholungen sind gleiche Bauelemente in Figur 2 mit denselben Bezugszeichen aus Figur 1 versehen. Im Unterschied zum Ausführungsbeispiel aus Figur 1 sind in Figur 2 die Leuchtmodule 201 seitlich am Dunstabzugsgehäuse 104 angebracht. Die Leuchtmittel 201 sind derart ausgerichtet, dass das emittierte Licht 108 in Richtung der Filterfläche 101 orientiert ist und von dieser in Richtung des Kochfeldes gestreut wird. FIG. 2 shows a schematic representation of a filter unit and the extractor housing laterally arranged lamps. To avoid repetition are the same components in FIG. 2 with the same reference numerals FIG. 1 Provided. In contrast to the embodiment of FIG. 1 are in FIG. 2 the lighting modules 201 mounted laterally on the extractor housing 104. The lighting means 201 are aligned such that the emitted light 108 is oriented in the direction of the filter surface 101 and is scattered by it in the direction of the cooking field.

Figur 3 zeigt in einer schematischen Darstellung eine Filtereinheit mit integrierten Leuchtmitteln. Wieder werden zur Vermeidung von Wiederholungen und zur besseren Übersichtlichkeit gleiche Bauelemente in Figur 3 mit denselben Bezugszeichen aus den Figuren 1 und 2 versehen. Die Filterlagen 101 sind von einem Rahmen 102 eingefasst. Zudem ist in Strömungsrichtung vor den Filterlagen 101 eine Decklage 103 angeordnet und in Strömungsrichtung hinter den Filterlagen 101 eine Decklage 301 angeordnet. Der Rahmen 102 und die beiden Decklagen 103 und 301 bilden ein geschlossenes Gehäuse, welches durch den Nutzer als Einheit in das Dunstabzugsgehäuse zu Reinigungszwecken entnehmbar ist. Die Decklagen sind als metallische Designblenden ausgestaltet, über deren Öffnungen in Form von breiten Schlitzen die angesaugte Luft in den Filter und wieder heraus gelangt. An der Unterseite der Decklage 301, in Strömungsrichtung gesehen, sind zwei Leuchtmittel 302 befestigt. Somit umfasst die durch den Rahmen 102 und die beiden Decklagen 103 und 301 eingefasste Filtereinheit die Filterlagen 101 und die Leuchtmittel 302. Die Leuchtmittel 302 sind derart ausgerichtet, dass das emittierte Licht durch die Filterfläche 101 in Richtung einer unter der Dunstabzugshaube vorgesehenen Arbeitsumgebung gestreut wird. FIG. 3 shows a schematic representation of a filter unit with integrated bulbs. Again, to avoid repetition and for clarity, the same components in FIG. 3 with the same reference numerals from the Figures 1 and 2 Provided. The filter layers 101 are enclosed by a frame 102. In addition, in the flow direction in front of the filter layers 101, a cover layer 103 is arranged and arranged in the flow direction behind the filter layers 101, a cover layer 301. The frame 102 and the two cover layers 103 and 301 form a closed housing, which can be removed by the user as a unit in the extractor housing for cleaning purposes. The cover layers are designed as metallic design panels, through whose openings in the form of wide slots, the sucked air into the filter and out again. On the underside of the cover layer 301, seen in the flow direction, two bulbs 302 are attached. Thus, the filter unit enclosed by the frame 102 and the two cover layers 103 and 301 comprises the filter layers 101 and the lighting means 302. The lighting means 302 are aligned such that the emitted light is scattered through the filter surface 101 in the direction of a working environment provided under the extractor hood.

Figur 4 zeigt eine Ausführungsform einer Filterlage 40 einer Filtermatte. Die Filtermatte kann aus mehreren Filterlagen 40 aufgebaut sein. Die Filterlage 40 besteht aus Kunststoffmaterial. Die Filterlage 40 ist in dieser Ausführungsform aus zwei Schichten 401, 402 aufgebaut. Die Schichten 401, 402 sind jeweils aus Kunststoffprofilen 403 gebildet. Die Anzahl der Kunststoffprofile 403 einer Schicht kann je nach Anforderung angepasst werden, sowie der Abstand zwischen den Kunststoffprofilen. In dieser Ausführungsform weisen die Kunststoffprofile 403 einen kreisförmigen Querschnitt auf. Der Querschnitt kann aber auch oval, flach oder vier- oder mehreckig sein. Zudem kann die Stärke der Kunststoffprofile 403 je nach Anforderung angepasst werden. Die Kunststoffprofile 403 sind in einer Schicht 401, 402 parallel zueinander in einem definierten Abstand zueinander angeordnet. Auf Grund des Abstandes der Kunststoffprofile zueinander entstehen Zwischenräume zwischen den Kunststoffprofilen 403, durch die der anströmende Wrasen durchtreten kann. FIG. 4 shows an embodiment of a filter layer 40 of a filter mat. The filter mat can be constructed from a plurality of filter layers 40. The filter layer 40 is made of plastic material. The filter layer 40 is constructed in this embodiment of two layers 401, 402. The layers 401, 402 are each made of plastic profiles 403 educated. The number of plastic profiles 403 of a layer can be adjusted as required, as well as the distance between the plastic profiles. In this embodiment, the plastic profiles 403 have a circular cross-section. The cross section may also be oval, flat or four- or polygonal. In addition, the strength of the plastic profiles 403 can be adjusted as required. The plastic profiles 403 are arranged in a layer 401, 402 parallel to each other at a defined distance from each other. Due to the distance between the plastic profiles to each other gaps between the plastic profiles 403, through which the incoming vapor can pass.

Zudem ist die Ausrichtung der Kunststoffprofile einer Schicht unterschiedlich zur Ausrichtung der Kunststoffprofile einer anderen Schicht. Vorzugsweise liegen diese Schichten übereinander. Insbesondere sind die Kunststoffprofile der einen Schicht in einem rechten Winkel zu den Kunststoffprofilen einer anderen Schicht ausgerichtet. An den Kontaktstellen, an denen die Kunststoffprofile der beiden Schichten aneinander anliegen, sind diese miteinander verbunden. Insbesondere können die Kunststoffprofile dort miteinander verklebt oder verschmolzen sein.In addition, the orientation of the plastic profiles of a layer is different to the orientation of the plastic profiles of another layer. Preferably, these layers are superimposed. In particular, the plastic profiles of one layer are aligned at a right angle to the plastic profiles of another layer. At the contact points where the plastic profiles of the two layers abut each other, these are interconnected. In particular, the plastic profiles may be glued or fused together there.

Die zumindest zwei Schichten sind somit unlösbar miteinander verbunden. Daher sind die Öffnungen in ihrer Größe fixiert, das heißt, dass sich die Größe der Öffnungen nicht verändern kann. Somit kann die Größe der Öffnungen bereits beim Herstellen der Filterlage je nach Anforderungen festgelegt werden und nicht mehr beispielweise während des Einbaus der Filtereinheit in eine Dunstabzugshaube versehentlich verändert werden oder durch die Anlagerung von Verunreinigungen und den Durchtritt von Partikeln verändert werden.The at least two layers are thus permanently connected to each other. Therefore, the openings are fixed in size, that is, the size of the openings can not change. Thus, the size of the openings can already be determined during the production of the filter layer depending on the requirements and no longer be changed accidentally during installation of the filter unit in a cooker hood or changed by the addition of impurities and the passage of particles.

Figur 5 zeigt eine weitere Ausführungsform einer Filterlage 50 einer Filtermatte. In dieser Ausführungsform ist das Kunststoffmaterial gewebt. Durch den Aufbau dieser Filterlage 50 entstehen auch Öffnungen 501 zwischen dem Kunststoffmaterial 502, insbesondere handelt es sich in dieser Ausführungsform bei den Öffnungen 501 um Maschen. FIG. 5 shows a further embodiment of a filter layer 50 of a filter mat. In this embodiment, the plastic material is woven. The construction of this filter layer 50 also creates openings 501 between the plastic material 502, in particular, in this embodiment, the openings 501 are meshes.
