Description

Die vorliegende Erfindung betrifft eine Dunstabzugshaube mit hinterleuchtetem Fettfilter.The present invention relates to an extractor hood with a 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 the case of extractor hoods, filter units, in particular filter cassettes, are used to separate impurities, in particular fat particles, from the vapor that is sucked in through the extractor hood. These filter units are therefore also referred to as grease filters.

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. In der DE 10 2015 006693 A1 ist ein weiteres Filterelement beschrieben, das aus Kunststofffäden bestehen kann.In the prior art, expanded metal filters are known 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 made of a plastic material. In the DE 10 2015 006693 A1 another filter element is described, which can consist of plastic threads.

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 work environment provided below the extractor hood. The working environment is usually the hob located under the extractor hood. In the prior art, the lights and the filter units of an extractor hood are separate components. In the prior art, lighting modules installed next to the filter unit and on the edge of the hood are usually provided for lighting.

Zudem ist in der US 5 145 500 A ein trimmbarer Filter für eine Dunstabzugshaube beschrieben. Hierbei deckt der Filter sowohl die Ansaugöffnung als auch das Licht der Dunstabzugshaube, das zu der Ansaugöffnung benachbart ist, ab. Hierbei wird zur Abdeckung des Lichts eine Plastikplatte verwendet, die mit dem eigentlichen Filterelement verbunden ist. Das Filterelement und die Plastikplatte sind über ein Profil durch eine Trennschiene mit doppelseitigen länglichen Kanälen verbunden. Die Vertiefung, in der das Licht aufgenommen ist, ist nach unten durch die Plastikplatte und zu der Ansaugöffnung durch eine weitere Platte abgegrenzt.In addition, the U.S. 5,145,500 A describes a trimmable filter for a cooker hood. Here, the filter covers both the suction opening and the light from the extractor hood that is adjacent to the suction opening. A plastic plate that is connected to the actual filter element is used to cover the light. The filter element and the plastic plate are connected via a profile by a separating rail with double-sided elongated channels. The recess in which the light is received is delimited at the bottom by the plastic plate and to the suction opening by a further plate.

In der DE 36 40 989 A1 ist eine Dunstabzugshaube beschrieben, die ein nach unten über ein Filtergitter abgeschlossenes Gehäuse aufweist, in dessen Innenräumen neben einem Spiralgehäuse einzelne Baugruppen, wie Schalter, Lampen und Kabel untergebracht und gegebenenfalls gegen Verschmutzen abgeschirmt und gegen Berühren gesichert sind. Auf das Filtergitter wird eine Filtermatte aufgelegt. Am rückwärtigen, von der Filtermatte nicht abgedeckten, Teil des Filtergitters ist eine Aussparung vorgesehen, welche von einer lichtdurchlässigen Platte abgedeckt ist. Oberhalb der Glasplatte sind Lampen angeordnet. 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. Zudem ist in der DE 11 90 157 B eine Absaughaube mit eingebautem Gebläse beschrieben, bei der das Gebläse an Stelle einer rotierenden Gebläseschaufel ein grob poröses Filter besitzt und bei der die Absaughaube nach unten von einer lichtdurchlässigen Schutzplatte abgedeckt ist. Im Inneren der Dunstabzugshaube außerhalb der Strömungsräume befinden sich Beleuchtungskörper zur Ausleuchtung der Absaughaubenunterseite.In the DE 36 40 989 A1 describes an extractor hood which has a housing closed at the bottom by a filter grille, in the interior of which, in addition to a spiral housing, individual assemblies such as switches, lamps and cables are housed and optionally shielded against contamination and secured against contact. A filter mat is placed on the filter grille. On the rear part of the filter grid, which is not covered by the filter mat, a recess is provided which is covered by a translucent plate. Lamps are arranged above the glass plate. In previous solutions, the lower surface of the extractor hood must therefore always be divided between the filter surface and the lighting. This is inevitably a compromise solution, since the respective area should be as large as possible for good filter and lighting performance. In addition, the DE 11 90 157 B describes a suction hood with a built-in fan, in which the fan has a coarse porous filter instead of a rotating fan blade and in which the suction hood is covered at the bottom by a transparent protective plate. Inside the extractor hood outside the flow spaces there are lighting fixtures for illuminating the underside of the extraction hood.

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 auf einfache Weise die zur Verfügung stehende Fläche optimal genutzt wird.The object of the present invention is to find an alternative arrangement of the two functional carriers, lighting and filters, in extractor hoods. In particular, an extractor hood is to be provided in which the available area can be optimally used in a simple manner.

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 further 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. 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.The invention is based on an extractor hood with an extractor housing that has an extraction opening, a fan accommodated in the extractor housing and a filter unit arranged at least partially in front of the extraction opening in the flow direction for cleaning the air sucked in by the fan. The filter unit has a filter mat with at least one filter layer, which consists of a plastic material and has openings, the size of which is fixed. According to the invention, at least one illuminant is arranged behind the filter unit in the direction of flow. The at least one illuminant is aligned such that a main direction of propagation of the emitted light of the illuminant is oriented in the direction of the filter unit in such a way 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.In the context of the invention, molded plastic is referred to as “plastic material”. Plastic is made from materials that mainly consist of macromolecules. The respective macromolecules of a plastic are polymers and are therefore made up of repeating basic units. The polymers can be made from natural substances or purely synthetic. For example, polyester, polypropylene or the like can be used as the plastic material. The filter layer has openings whose size is fixed. The "opening" is the passage opening or the space between filter webs made of plastic material in the respective filter layer. The filter bars are also referred to below as bars. The openings are determined by the distance between the filter webs. In the context of the invention, the openings are also referred to as holes or meshes. The incoming vapor can flow through the openings in the filter layer. Openings that are fixed in size are openings that cannot be changed in size, that is, the filter webs between the openings cannot be moved. The openings of a filter layer are thus permanently the same size and the size of the openings is predetermined during the production of a filter layer. The openings of a filter layer are preferably of the same size. The openings in the filter layer are particularly preferably fine or small compared to the meshes from the expanded metal layers known from the prior art. The "lamp" is intended to emit visible light. The light source of the lighting device can be, for example, an LED (light emitting diode), an incandescent lamp or a halogen spotlight. In the case of lamps with a directional characteristic, that is to say an angle-dependent light intensity, "main direction of propagation" means the direction in which the lamp emits the highest percentage of light intensity.

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. The luminous means is preferably arranged on a plane that is essentially 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 laterally offset from the filter surface and is arranged on a plane essentially 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 into the filter unit, and the filter unit can be removed. This unit is built into the extractor hood and can be removed for cleaning. In this case, the illuminants are particularly advantageously designed to be resistant to cleaning, for example in a dishwasher.

Erfindungsgemäß ist das Kunststoffmaterial zumindest teilweise lichtdurchlässig und/oder lichtstreuend.According to 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 setting of the lighting means includes a change in a color temperature, a light intensity, a direction of light emission, an illumination area and / or a duration of 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.In the context of the invention, color temperature is a measure for determining the respective color impression of a light source. The strength of the light is referred to as light intensity in the context of the invention. The intensity is the proportion of the total amount of light that is emitted by a light source in a given spatial direction. According to the invention, the direction of the output of the light from a light source is referred to as the direction of light output. According to the invention, the illumination area is the area in a room or an area which is wholly or partially illuminated or irradiated by means of the emitting light of a light source. The duration of the light output can include the output duration itself and, if necessary, intervals to be observed between the output of the light. Accordingly, the output of the light can 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 sets the at least one lighting 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, a cover layer is provided in front of the filter mat in the direction of flow, which is arranged essentially parallel to the surface of the filter mat and is at least partially air-permeable. The cover layer is advantageously 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 in the same way as the other filter layers and also be different in appearance and function. In addition, a cover layer can also be arranged behind the filter layer in the direction of flow. The task of the top layer is, for example, the mechanical protection of the susceptible plastic filter inner layers and / or the visual enhancement of the overall filter. The top layer (s) should be sufficiently air-permeable 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 surrounded by a surrounding frame. In this way, all filter layers are safely enclosed in a frame. This has the advantage that the filter element is easier to handle if it is to be removed from the extractor hood for cleaning purposes, for example.

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. 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.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. In the context of the invention, an element is referred to as a layer from which a filter layer is at least partially formed and which consists of a plastic material. According to one embodiment, a filter layer has at least two layers which lie one on top of the other in the filter layer, that is to say are stacked, and through which inflowing vapor flows one after the other. The layers can be present as separate elements before the assembly of the filter layer. The layers of a filter layer are preferably formed from plastic profiles. In the context of the invention, a profile is a long, thin element that is flexible or rigid. The length of the profile can be limited in a simple manner depending on the size of the layer to be used. The cross section of the plastic profile can, for example, be circular, oval, flat or square or polygonal. A layer of a filter layer can have several plastic profiles, which means that 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. Die Herstellung als gewebtes oder geflochtenes Material und die Herstellung als Kunststoffplatte lässt sich auf der einen Seite einfach durchführen. Auf der anderen Seite kann beim Weben, Flechten oder Knüpfen beispielsweise die Maschenweite, das heißt die Größe der Öffnungen oder Abstände, die zwischen dem Kunststoff vorliegen, gezielt eingestellt werden.Furthermore, an embodiment of the filter element according to the invention is preferred in which the filter layer consists of woven or braided plastic material or is a plastic plate with openings made. In the embodiments as a woven or braided plastic material, the filter webs, which delimit the openings formed as meshes, are formed by threads. In the embodiment as a plastic plate, the filter webs are formed by the strip of material remaining after the holes have been made in the plastic plate. The production as a woven or braided material and the production as a plastic plate can be carried out easily on the one hand. On the other hand, when weaving, braiding or knotting, for example, the mesh size, that is to say the size of the openings or spaces between the plastic, can be set in a targeted manner.

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. Figure 1 shows a schematic representation of a filter unit with integrated lighting means. The plastic filter layers 101 can be designed in any color. The filter layers 101 are framed by a frame 102 and a cover layer 103 arranged in front of the filter layers 101 in the direction of flow. The top layer is designed as a metallic design panel, through the openings of which in the form of wide slits the sucked in air enters the filter. The filter unit 101 is mounted in an extractor housing 104 in such a way that the filter unit can be easily removed and reinserted 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 attached in a plane surface parallel to the filter surface. The lamps are intended to emit visible light. Furthermore, a control device, not shown, is provided for setting the lighting means. The lighting means can be, for example, an LED (light emitting diode), an incandescent lamp or a halogen spotlight. The light module further comprises at least one holder for the light source and at least one contact point for connecting the light source 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 air 106 mixed with fat particles is sucked in by a fan (not shown) and passed through the filter 101 via the openings in the design panel 103. The air 107 cleaned in the process is guided inside the extractor housing past the lighting means to the fan. The light 108 emitted by the lighting means 105 is oriented in the direction of the filter surface 101 and passes through it. The light 108 is scattered in the direction of the hob arranged under the extractor hood.

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. Figure 2 shows a schematic representation of a filter unit and lamps arranged laterally in the extractor housing. To avoid repetition, the same components are in Figure 2 with the same reference numerals Figure 1 Mistake. In contrast to the exemplary embodiment Figure 1 are in Figure 2 the light modules 201 attached to the side of the extractor housing 104. The lighting means 201 are aligned in such a way that the emitted light 108 is oriented in the direction of the filter surface 101 and is scattered by this in the direction of the hob.

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. Figure 3 shows a schematic representation of a filter unit with integrated lighting means. Again, to avoid repetitions and for better clarity, the same components are shown in Figure 3 with the same reference numerals from Figures 1 and 2 Mistake. The filter layers 101 are enclosed by a frame 102. In addition, a cover layer 103 is arranged in front of the filter layers 101 in the flow direction and a cover layer 301 is arranged behind the filter layers 101 in the flow direction. 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 the openings of which in the form of wide slits the sucked in air gets into the filter and out again. Two illuminants 302 are attached to the underside of the cover layer 301, seen in the direction of flow. 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 by 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. Figure 4 shows an embodiment of a filter layer 40 of a filter mat. The filter mat can be constructed from several filter layers 40. The filter layer 40 is made of plastic material. In this embodiment, the filter layer 40 is made up of two layers 401, 402. The layers 401, 402 are each formed from plastic profiles 403. The number of plastic profiles 403 in a layer can be adapted as required, as can the distance between the plastic profiles. In this embodiment, the plastic profiles 403 have a circular cross section. The cross section can, however, also be oval, flat or square or polygonal. In addition, the thickness of the plastic profiles 403 can be adjusted as required. the Plastic profiles 403 are arranged in a layer 401, 402 parallel to one another at a defined distance from one another. Because of the distance between the plastic profiles, there are spaces between the plastic profiles 403, through which the inflowing 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 alignment of the plastic profiles of one layer is different from the alignment of the plastic profiles of another layer. These layers are preferably one above the other. 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 rest against one another, they are connected to one another. In particular, the plastic profiles can be glued or fused to one another 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 therefore inextricably linked to one another. The size of the openings is therefore fixed, which means that the size of the openings cannot change. Thus, the size of the openings can already be determined during the manufacture of the filter layer depending on the requirements and no longer be accidentally changed, for example during the installation of the filter unit in an extractor hood, or changed by the accumulation 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. Figure 5 shows a further embodiment of a filter layer 50 of a filter mat. In this embodiment the plastic material is woven. The structure of this filter layer 50 also creates openings 501 between the plastic material 502; in particular, in this embodiment the openings 501 are meshes.
