Description

Die vorliegende Erfindung betrifft eine Dunstabzugshaube.The present invention relates to an extractor hood.

Dunstabzugshauben dienen dem Abzug von Feuchtigkeit, GerĆ¼cheh und/oder Fett aus der Raumluft. Da insbesondere beim KĆ¼cheneinsatz hƤufig fettige oder fetthaltige Wrasen durch eine Eintrittsƶffnung und Filter der Dunstabzugshaube strƶmen, ergibt sich mit der Zeit eine Belegung der eingesetzten Filter, sodass ein Austausch oder eine Reinigung der Filter erfolgen muss. Bekannt sind Dunstabzugshauben, bei denen eine Vorfilterung Ć¼ber einen gitterartigen Fettfilter erfolgt, der gleichzeitig ein Verblendelement fĆ¼r den Innenraum des AbzugshaubengehƤuses ist. Dabei ist es wĆ¼nschenswert, den Filter einerseits sicher zu halten und andererseits leicht austauschen oder reinigen zu kƶnnen.Extractor hoods are used to extract moisture, odors and / or grease from the room air. Since greasy or greasy fumes frequently flow through an inlet opening and filter of the extractor hood, in particular during kitchen use, there is an occupancy of the filters used over time, so that an exchange or a cleaning of the filter must take place. There are known extractor hoods, in which a prefilter via a grid-like grease filter, which is also a facing element for the interior of the hood housing. It is desirable to keep the filter on the one hand safely and on the other hand easily replace or clean.

Die DE 10 2006 055 202 offenbart eine Dunstabzugshaube mit einem Filter zum Filtern von abzuziehenden Wrasen und einem Filterrahmen zum Verbinden des Filters mit einem FĆ¼hrungselement, wobei der Filter mittels einem Magnetband zum raschen Lƶsen mit dem Filterrahmen verbunden ist.The DE 10 2006 055 202 discloses an extractor hood having a filter for filtering fumes to be drawn and a filter frame for connecting the filter to a guide member, the filter being connected to the filter frame by means of a magnetic tape for rapid release.

Die CN 201547868 U offenbart einen Griff fĆ¼r ein Filterelement einer Dunstabzugshaube. Der Griff weist eine untere Abdeckung und eine obere Abdeckung auf. In der oberen Abdeckung ist ein schwenkbares FlĆ¼gelelement vorgesehen. Das schwenkbare FlĆ¼gelelement wird Ć¼ber ein BetƤtigungselement und eine Federanordnung betƤtigt.The CN 201547868 U discloses a handle for a filter element of an extractor hood. The handle has a bottom cover and a top cover. In the upper cover a pivotable wing member is provided. The pivotable wing element is actuated via an actuating element and a spring arrangement.

Die GB 22 49 493 A offenbart eine Dunstabzugshaube mit drehbar gelagerten Filterelementen.The GB 22 49 493 A discloses an extractor hood with rotatably mounted filter elements.

Vor diesem Hintergrund besteht eine Aufgabe der vorliegenden Erfindung darin, eine verbesserte Dunstabzugshaube zu schaffen.Against this background, an object of the present invention is to provide an improved extractor hood.

DemgemƤƟ wird eine Dunstabzugshaube vorgeschlagen, welche ein GehƤuse und ein an dem GehƤuse angeordnetes lƶsbares flƤchiges Filterelement umfasst. Das Filterelement ist mit Hilfe mindestens eines Magneten gehalten, und wenigstens ein Abschnitt des Filterelements ist zum Entnehmen oder Lƶsen des Filterelements von dem GehƤuse drehbar in Richtung zu einem Innenraum des GehƤuses um eine Wippachse angeordnet.Accordingly, an extractor hood is proposed, which comprises a housing and arranged on the housing detachable flat filter element. The filter element is held by means of at least one magnet, and at least a portion of the filter element is arranged for removing or releasing the filter element from the housing rotatable in the direction of an interior of the housing about a rocking axis.

Die zumindest eingeschrƤnkte Drehbarkeit um die Wipp- oder Rotationsachse ermƶglicht ein HineindrĆ¼cken des Filterelements um die Wippachse, wodurch eine Entnahme desselben von dem GehƤuse vereinfacht ist. Im normalen Betriebszustand schlieƟt das flƤchige Filterelement beispielsweise bĆ¼ndig mit dem GehƤuse ab und weist mit einer im Wesentlichen glatten OberflƤche zum Bediener oder dem KĆ¼chengerƤt hin.The at least limited rotatability about the rocking or rotation axis allows the filter element to be pushed in around the rocking axis, as a result of which removal thereof from the housing is simplified. In the normal operating state, for example, the flat filter element terminates flush with the housing and points with a substantially smooth surface to the operator or the kitchen appliance.

Die Drehbarkeit um eine Wippachse ermƶglicht, dass ein Abschnitt des Filterelements in den Innenraum des GehƤuses gedrĆ¼ckt werden kann, wƤhrend der andere jenseits der Wippachse vorliegende Abschnitt in Richtung aus dem GehƤuse heraus, also zum Bediener hin, greifbar wird. Auf sonst Ć¼bliche Griffe oder komplizierte Handhabungsmittel, welche von auƟen sichtbar sind, kann verzichtet werden.The rotatability about a rocking axis allows a portion of the filter element can be pressed into the interior of the housing, while the other beyond the rocking axis portion in the direction out of the housing, so the operator out, becomes tangible. On otherwise common handles or complicated handling means which are visible from the outside, can be dispensed with.

Dadurch ist das Filterelement leichter zu reinigen und fĆ¼hrt zu einem verbesserten Ƥsthetischen Eindruck der Dunstabzugshaube.As a result, the filter element is easier to clean and leads to an improved aesthetic impression of the hood.

Vorzugsweise ist das gesamte Filterelement drehbar. Alternativ kann auch nur ein Teil des Filterelements, beispielsweise ein Segment oder Abschnitt drehbar sein, so dass ein potenzieller Bediener in einen Eingriff eingreifen kann.Preferably, the entire filter element is rotatable. Alternatively, only a part of the filter element, for example a segment or section, can be rotatable so that a potential operator can engage in an engagement.

Das Filterelement ist vorzugsweise in Richtung zu einer Anstrƶmseite lƶsbar oder entnehmbar.The filter element is preferably detachable or removable in the direction of an inflow side.

Bei einer AusfĆ¼hrungsform der Dunstabzugshaube ist eine Magnethalterung derart angeordnet, dass MagnetkrƤfte ausschlieƟlich in Richtung einer FlƤchennormalen des flƤchigen Filterelements wirken. Dabei ist es mƶglich, Magnete entweder an dem Filterelement, beispielsweise umlaufend anzuordnen oder an dem GehƤuse anzuordnen. Es ist auch mƶglich, sowohl das Filterelement wie auch das GehƤuse mit Magneten zu versehen, damit ein ausreichender Kraftschluss gewƤhrleistet ist.In one embodiment of the extractor hood, a magnet holder is arranged such that magnetic forces act exclusively in the direction of a surface normal of the flat filter element. It is possible to arrange magnets either on the filter element, for example circumferentially or to arrange on the housing. It is also possible to provide both the filter element as well as the housing with magnets, so that a sufficient adhesion is ensured.

Bei einer weiteren AusfĆ¼hrungsform der Dunstabzugshaube ist das Filterelement von dem GehƤuse ausschlieƟlich in lateraler Richtung gestĆ¼tzt oder gehalten. Insofern dient das GehƤuse beispielsweise in der Art eines Rahmens, der um das Filterelement lƤuft, der Positionierung. Die Halterung erfolgt durch MagnetkrƤfte senkrecht zur FlƤchenormalen des Filterelements.In a further embodiment of the extractor hood, the filter element is supported or held by the housing exclusively in the lateral direction. In this respect, the housing serves, for example, in the manner of a frame which runs around the filter element, the positioning. The holder is made by magnetic forces perpendicular to the surface normal of the filter element.

Es ist zum Beispiel mƶglich, dass das Filterelement in einem eingesetzten Zustand randseitig umlaufend an einem Rahmen des GehƤuses anliegt und von mehreren Magneten gehalten wird.It is for example possible that the filter element in an inserted state peripherally rests against a frame of the housing and is held by a plurality of magnets.

In einer AusfĆ¼hrungsform der Dunstabzugshaube umfasst das GehƤuse mindestens zwei gegenĆ¼ber liegend angeordnete Auflageabschnitte fĆ¼r das Filterelement. Entlang der Auflageabschnitte kann insbesondere die magnetische Halterung angebracht sein.In one embodiment of the extractor hood, the housing comprises at least two oppositely arranged support sections for the filter element. In particular, the magnetic holder can be attached along the support sections.

Bei einer Variante der Dunstabzugshaube umfasst ein jeweiliger Auflageabschnitt einen Halteabschnitt zum Anliegen des Filterelements in dem eingesetzten Zustand und einen StĆ¼tzabschnitt zum StĆ¼tzen des Filterelements in einem in den Innenraum des GehƤuses gedrehten Zustand. Dabei sind vorzugsweise der Halteabschnitt und der StĆ¼tzabschnitt im Bereich der Wippachse aneinander grenzend. Insofern gibt ein Winkel zwischen Halteund StĆ¼tzabschnitt den maximalen Rotationsgrad um die Wipp- oder Rotationsachse vor. DrĆ¼ckt der Bediener das Filterelement in Richtung zum Innenraum des GehƤuses, wird das Filterelement durch die StĆ¼tzabschnitte gestĆ¼tzt.In a variant of the extractor hood, a respective support section comprises a holding section for engaging the filter element in the inserted state and a support section for supporting the filter element in a state rotated into the interior of the housing. In this case, the holding section and the supporting section are preferably adjacent to one another in the region of the rocking axis. In this respect, an angle between holding and supporting section predetermines the maximum degree of rotation about the rocking or rotation axis. When the operator pushes the filter element toward the interior of the housing, the filter element is supported by the support sections.

Vorzugsweise ist das Filterelement ausschlieƟlich im Bereich der Halteabschnitte magnetisch gehalten. Dadurch kann die Anzahl von Magneten reduziert werden, da im Normalbetrieb das Filterelement in der Regel nicht auf dem StĆ¼tzabschnitt anliegt.Preferably, the filter element is held magnetically only in the region of the holding portions. As a result, the number of magnets can be reduced since, in normal operation, the filter element generally does not rest on the support section.

Die Dunstabzugshaube kann derart ausgestaltet sein, dass das Filterelement anstrƶmseitig eine Handhabungsmarkierung aufweist. Die Handhabungsmarkierung, beispielsweise ein Symbol, zeigt dem Bediener an, dass an dieser Stelle das Filterelement in Richtung zum Innenraum beweglich drehbar ist.The extractor hood can be configured such that the filter element has a handling mark on the inflow side. The handling mark, for example a symbol, indicates to the operator that at this point the filter element is rotatably movable in the direction of the interior.

Bei einer AusfĆ¼hrungsform der Dunstabzugshaube sind die Magnete ausschlieƟlich an dem GehƤuse angeordnet. Insofern wird die Herstellung des Filterelements, welches beispielsweise als Verbrauchsmittel oder Ersatzteil geliefert werden kann, vereinfacht.In one embodiment of the extractor hood, the magnets are arranged exclusively on the housing. In this respect, the production of the filter element, which can be supplied, for example, as a consumable or spare part, simplified.

Das Filterelement ist insbesondere als Fettfilter ausgebildet. Dabei kann das Filterelement einen umlaufenden Rahmen und ein in dem Rahmen vorgesehenes Gitter als Fettfilter umfassen.The filter element is designed in particular as a grease filter. In this case, the filter element may comprise a peripheral frame and provided in the frame grid as a grease filter.

Es wird ferner ein Filterelement vorgeschlagen, welches insbesondere fĆ¼r eine Dunstabzugshaube wie oben beschrieben angepasst ist, und welches als Verblendelement fĆ¼r die Dunstabzugshaube eine im Wesentlichen ebene FlƤche ausbildet und einen Handhabungsabschnitt in der FlƤche aufweist, welcher zum Freigeben eines Eingriffs drehbar in Richtung zu einem Innenraum der Dunstabzugshaube um eine Wippachse drehbar ist. Insofern kƶnnen konventionelle Fettfilterelemente durch das Vorbeschriebene ersetzt werden, um eine bessere Handhabbarkeit und Ƅsthetik zu erzielen.It is also proposed a filter element, which is adapted in particular for an extractor hood as described above, and which forms a substantially flat surface as Verblendelement for the hood and has a handling portion in the surface, which for Enable an engagement is rotatable in the direction of an interior of the hood around a rocking axis is rotatable. In this respect, conventional grease filter elements can be replaced by the above to achieve better handleability and aesthetics.

In einer weiteren AusfĆ¼hrungsform der Dunstabzugshaube umfasst dieselbe mehrere magnetisch gehaltene Filterelemente, welche nebeneinander angeordnet sind.In a further embodiment of the extractor hood, the same comprises a plurality of magnetically held filter elements which are arranged next to one another.

Die Fig. 1 zeigt eine perspektivische Ansicht einer ersten AusfĆ¼hrungsform einer Dunstabzugshaube. Die Dunstabzugshaube 1 dient insbesondere dem Abzug von Wrasen oberhalb von Kochstellen im Haushalt. Dazu ist ein Abluftschacht 6 mit einem GehƤuseteil 2 verbunden, welcher bedienerseitig, also oberhalb des jeweiligen Kochfeldes, durch glatt abschlieƟende FettfiltereinsƤtze oder Filterelemente 3, 4, 5 abgeschlossen ist. Man erkennt in der Fig. 1, dass DĆ¼nste in einer Anstrƶmrichtung 7 auf die Filterelemente 3, 4, 5 treffen, dort weitestgehend von Fett oder anderen trƶpfchenfƶrmigen Verunreinigungen gereinigt werden und dann Ć¼ber den Abluftschacht 6 beispielsweise in die Umgebung abgeblasen werden (vgl. Pfeil 8). Dabei sind in der Fig. 1 weitere Elemente der Dunstabzugshaube wie LĆ¼fter oder zusƤtzliche im GehƤuseinneren vorliegende Filterelemente nicht dargestellt. Die Filterelemente 3, 4, 5 sind in bzw. an dem GehƤuse 2 magnetisch gehalten.The Fig. 1 shows a perspective view of a first embodiment of an extractor hood. The extractor hood 1 is used in particular for the withdrawal of vapors above cooking places in the home. For this purpose, an exhaust duct 6 is connected to a housing part 2, which is the operator side, so above the respective hob, completed by smooth final FettfiltereinsƤtze or filter elements 3, 4, 5. One recognizes in the Fig. 1 in that fumes strike the filter elements 3, 4, 5 in an inflow direction 7, where they are largely cleaned of grease or other droplet-like impurities and then blown off via the exhaust duct 6 into the environment, for example (see arrow 8). There are in the Fig. 1 other elements of the hood as fan or additional present in the housing interior filter elements not shown. The filter elements 3, 4, 5 are magnetically held in or on the housing 2.

Fig. 2A zeigt die Dunstabzugshaube 1 mit entfernten Filterelementen 3, 4, 5. In der perspektivischen Darstellung in Fig. 2A sieht man perspektivisch von unten in den Innenraum 9 des GehƤuses 2 der Dunstabzugshaube 1. Die Filterelemente 3, 4, 5 sind flƤchig und haben einen rechteckigen Grundriss. Im eingesetzten Zustand, wie in der Fig. 1 dargestellt ist, liegen die Filterelemente randseitig auf einem jeweiligen GehƤuserahmen 12 an. In etwa der Mitte der FlƤche des jeweiligen Filterelements 3, 4, 5 sind Magneten 11 im Innenraum des GehƤuses 2 vorgesehen, welche derart ausgestaltet sind, dass sie das Gewicht der Filterelemente auch in mit Verunreinigung beladenem Zustand halten. Fig. 2A shows the cooker hood 1 with removed filter elements 3, 4, 5. In the perspective view in Fig. 2A one sees in perspective from below into the interior 9 of the housing 2 of the extractor hood 1. The filter elements 3, 4, 5 are flat and have a rectangular plan. In the inserted state, as in the Fig. 1 is shown, the filter elements are on the edge of a respective housing frame 12. In approximately the middle of the surface of the respective filter element 3, 4, 5 magnets 11 are provided in the interior of the housing 2, which are designed such that they also keep the weight of the filter elements in contaminated state.

In der Fig. 2B ist eine schematische Querschnittsansicht eines Ausschnittes der AusfĆ¼hrungsform der Dunstabzugshaube angedeutet. Um die Filterelemente 3, 4, 5 zu entfernen, kƶnnen diese um eine Wippachse 10 in den Innenraum 9 des GehƤuses 2 gedrĆ¼ckt werden. Dabei muss der Bediener lediglich entlang beispielsweise einer Markierung 14 die Magnetkraft teilweise Ć¼berwinden und den markierten Abschnitt des Filterelements 3 in Richtung zum Innenraum 9 hineindrĆ¼cken. Dadurch lƶst sich das Filterelement 3 zumindest teilweise von dem jeweiligen Magneten 11, so dass die nicht in den Innenraum 9 eingedrĆ¼ckte Seite nach unten oder auƟen ragt und gegriffen werden kann.In the Fig. 2B is a schematic cross-sectional view of a section of the embodiment of the extractor hood indicated. In order to remove the filter elements 3, 4, 5, they can be pressed about a rocking axis 10 in the interior 9 of the housing 2. In this case, the operator merely has to partially overcome the magnetic force along, for example, a marking 14 and push the marked section of the filter element 3 in the direction of the interior 9. This will solve that Filter element 3 at least partially from the respective magnet 11, so that the not pressed into the interior 9 side down or outwardly protrudes and can be gripped.

Insofern wird kein mechanischer Griff oder ein zusƤtzliches Handhabungselement zum Entfernen und Austauschen oder Reinigen der Filterelemente 3, 4, 5 benƶtigt. Da kein Griffelement vorgesehen sein muss, ist das Filterelement auch weniger schmutzanfƤllig. Durch die magnetische Halterung sowie Kombination mit der Rotationsmƶglichkeit, ergeben sich eine besonders einfache Handhabung und ein Ƥsthetischer Gesamteindruck. Man erkennt in der Fig. 2B beispielsweise im gestrichelten Zustand, dass sich mit bestimmungsgemƤƟ montiertem Filterelement 3 im GehƤuse 2 ein glatter GehƤuseabschluss, wie es sich beispielsweise in der Fig. 1 darstellt, ergibt und ansonsten, das durch einen Bediener an der Stelle 14 in das GehƤuseinnere gedrĆ¼ckte Filterelement, welches um eine Wipp- oder Rotationsachse im Bereich der Magnetkopplung 11 verdreht ist, zum Entnehmen schrƤg steht.In this respect, no mechanical handle or an additional handling element for removing and replacing or cleaning the filter elements 3, 4, 5 is required. Since no handle element must be provided, the filter element is less susceptible to dirt. The magnetic holder and combination with the possibility of rotation result in a particularly simple handling and an overall aesthetic impression. One recognizes in the Fig. 2B For example, in the dashed state, that with properly mounted filter element 3 in the housing 2, a smooth housing closure, as is the case for example in the Fig. 1 represents, results and otherwise, which is biased by an operator at the point 14 in the housing interior filter element which is rotated about a rocking or rotation axis in the region of the magnetic coupling 11, for removal is inclined.

Die Fig. 3 zeigt eine perspektivische Ansicht einer zweiten AusfĆ¼hrungsform einer Dunstabzugshaube, die ebenfalls mit magnetisch gekoppelten, aber dennoch drehbaren Filterelementen ausgestattet ist. Die Fig. 3 zeigt die Hand eines Bedieners 20, der das mittlere Filterelement 4 in den Innenraum des GehƤuses 2 drĆ¼ckt, um dasselbe abzunehmen und beispielsweise zu reinigen. Das linke Filterelement 3 ist bereits von dem GehƤuse 2 entfernt. Im Bereich hinter dem Filterelement 3, links, erkennt man die Wippachse 10, welche im Vergleich zu den Fig. 1 bis 2 senkrecht orientiert ist. Durch den Druck, auf die in der Orientierung der Fig. 3 rechten Seite des mittleren Filterelements 4, klappt das Element 4 Ć¼ber die Wipphalterung und verbleibt in der dargestellten SchrƤglage, so dass es einfach gegriffen werden kann.The Fig. 3 shows a perspective view of a second embodiment of an extractor hood, which is also equipped with magnetically coupled, yet rotatable filter elements. The Fig. 3 shows the hand of an operator 20, which presses the middle filter element 4 in the interior of the housing 2 to remove the same and, for example, to clean. The left filter element 3 is already removed from the housing 2. In the area behind the filter element 3, left, you can see the Wippachse 10, which in comparison to the Fig. 1 to 2 is oriented vertically. Due to the pressure on the orientation of the Fig. 3 right side of the middle filter element 4, the element 4 folds over the tilt bracket and remains in the illustrated tilt, so that it can be easily grasped.

Die Fig. 4A und 4B zeigen eine erste AusfĆ¼hrungsform eines einsetzbaren Filterelements 3. Das Filterelement 3 hat dabei einen Filterelementrahmen 15, der beispielsweise ein Metallgitter 16 als Fettfilter hƤlt. An dem Filterelement 3 ist ferner eine Markierung 14 vorgesehen, welche dem Bediener anzeigt, wo es in das GehƤuse innen wippbar eingedrĆ¼ckt werden kann.The FIGS. 4A and 4B show a first embodiment of an insertable filter element 3. The filter element 3 has a filter element frame 15, which holds, for example, a metal grid 16 as a grease filter. On the filter element 3, a mark 14 is further provided, which indicates to the operator, where it can be pressed inside the housing rocker.

Die Fig. 4B zeigt eine schematische Querschnittsansicht eines Ausschnittes des Filterelements im GehƤuse. Die Fig. 4B zeigt dabei, dass in der oberen Figur im eingesetzten Zustand das Filterelement 3 an einem Auflageabschnitt 13 anliegt. Der Auflageabschnitt 13 kann beispielsweise zwei gegenĆ¼berliegende RƤnder des Filterelements 3 halten. Dabei hat der Auflageabschnitt einen Halteabschnitt 13A, welcher horizontal ausgerichtet ist und das Filterelement im normalen Betriebszustand derart hƤlt, dass es beispielsweise mit einer GehƤuseoberflƤche bĆ¼ndig abschlieƟt. Ein zweiter, an den Halteabschnitt 13A anschlieƟender StĆ¼tzabschnitt 13B, dient dazu, das Filterelement 3 im eingedrĆ¼ckten Zustand, wie es in der unteren Figur der Fig. 4B dargestellt ist, zu stĆ¼tzen. Der Halteabschnitt 13A sowie der StĆ¼tzabschnitt 13B grenzen im Bereich der Wippachse 10 aneinander. Der Halteabschnitt 13A verlƤuft insofern in das GehƤuseinnere hinein. Dies ist in der Fig. 3 durch eine gestrichpunktete Linie am Beispiel des mittleren Filterelements 3 angedeutet.The Fig. 4B shows a schematic cross-sectional view of a section of the filter element in the housing. The Fig. 4B shows that in the upper figure in the inserted state, the filter element 3 rests against a support portion 13. The support portion 13 may, for example, hold two opposite edges of the filter element 3. In this case, the support portion has a holding portion 13A, which is oriented horizontally and holds the filter element in the normal operating state such that it is flush, for example, with a housing surface. A second, adjoining the holding portion 13A support portion 13B, serves the filter element 3 in the depressed state, as shown in the lower figure of Fig. 4B is shown to support. The holding section 13A and the support section 13B adjoin one another in the region of the rocking axis 10. The holding portion 13A extends so far into the housing interior. This is in the Fig. 3 indicated by a dashed line on the example of the central filter element 3.

Die Fig. 5 bis 7 zeigen schematische Querschnittsansichten eines Ausschnitts eines Filterelements in einem GehƤuse mit einer Magnethalterung. In der Fig. 5 ist das GehƤuse anstrƶm- oder bedienerseitig von dem Filterelement 3 verschlossen. Dabei liegt das Filterelement 3 auf einem Halteabschnitt 13A, durch Magnete 11 gehalten, fest. Der von dem Halteabschnitt 13A in einem Winkel zum Innenraum des GehƤuses abzweigende StĆ¼tzabschnitt 13B dient der FĆ¼hrung des Filterelements 3 im eingedrĆ¼ckten Zustand, also um die Wippachse 10 gedrehten Zustand, beim Entnehmen. Dies ist in der Fig. 6 angedeutet. Dabei sind auch im Bereich des StĆ¼tzabschnitts 13B Magnete 11 vorgesehen, so dass das Filterelement 3 nicht nach unten herausfallen kann. In der Fig. 7 ist der gepunktet angedeutete, kreisrunde Ausschnitt der Fig. 5 nƤher dargestellt. Man erkennt, dass das Filterelement 3 im Wesentlichen horizontal gelagert und gehalten wird. Dabei dient die schematisch angedeutete GehƤusewand 2 lateral L der FĆ¼hrung des Filterelements 3. Es kann insofern nicht horizontal, also parallel zu seiner flƤchigen Ausdehnung, verrutschen. Vertikal, also in Richtung zur FlƤchennormalen N des Filterelements 3, hƤlt die Magnetkraft des Magneten 11 das Filterelement 3 in seiner Position. Die MagnetkrƤfte sind dabei derart ausgestaltet, dass das Filterelement 3 bei bestimmungsgemƤƟem Einbauzustand und Betriebsparametern festhƤlt. Dabei wird das Filterelement 3 an dem Halteabschnitt 13A gelagert.The Fig. 5 to 7 show schematic cross-sectional views of a section of a filter element in a housing with a magnetic holder. In the Fig. 5 If the housing is closed by the filter element 3 against the flow or operator side. In this case, the filter element 3 is on a holding portion 13 A, held by magnets 11, fixed. The branching off of the holding portion 13A at an angle to the interior of the housing support portion 13B serves to guide the filter element 3 in the depressed state, ie rotated about the rocking axis 10 state when removing. This is in the Fig. 6 indicated. Magnets 11 are also provided in the region of the support section 13B, so that the filter element 3 can not fall down. In the Fig. 7 is the dotted indicated, circular section of the Fig. 5 shown in more detail. It can be seen that the filter element 3 is stored and held substantially horizontally. In this case, the schematically indicated housing wall 2 laterally L of the guide of the filter element 3. It can not horizontally so far, so parallel to its areal extent, slip. Vertically, ie in the direction of the surface normal N of the filter element 3, the magnetic force of the magnet 11 keeps the filter element 3 in its position. The magnetic forces are designed such that the filter element 3 holds in the intended installation state and operating parameters. In this case, the filter element 3 is mounted on the holding portion 13A.

Die Fig. 8A und 8B zeigen eine zweite AusfĆ¼hrungsform eines Filterelements, welches in eine Dunstabzugshaube konventioneller Bauart oder auch in Dunstabzugshauben der vorbeschriebenen AusfĆ¼hrungsbeispiele einsetzbar ist. Die Fig. 8A zeigt eine perspektivische Ansicht des Filterelements 17. Dabei hat das Filterelement 17 einen Ausschnitt, der als Handhabungsklappe dient. Der Ausschnitt 18 ist, wie in der Fig. 8A dargestellt, im Normalbetrieb geschlossen. In der Fig. 8B ist das Filterelement 3 im eingebauten und entnehmbaren Zustand angedeutet. Die obere Darstellung der Fig. 8A zeigt das Filterelement 17 wie es von einem Magneten, welcher gehƤuseinnenseitig 9 angeordnet ist, gehalten wird. Die Handhabungsklappe oder Abdeckung 18 schlieƟt damit bĆ¼ndig mit der restlichen OberflƤche des Filterelements 3 ab. Allerdings ist die Handhabungsklappe Ć¼ber einen Wippmechanismus zu ƶffnen. Dies ist in der Fig. 8B unten dargestellt. Durch einen Druck in Pfeilrichtung in Richtung R zum GehƤuseinnenraum 9 hin, kann ein Eingriff 19 freigegeben werden, so dass das Filterelement 3 hƤndisch die Magnetkraft des Magneten oder der Magneten 11 Ć¼berwindend, entfernbar ist. Dabei ist nicht das vollstƤndige Filterelement um eine Wippachse drehbar, sondern das Filterelement umfasst einen Abschnitt mit einer Wippoder Drehachse 10, um den Eingriff 19 freizugeben. Auch bei der AusfĆ¼hrungsform der Fig. 8 ergibt sich ein Ƥsthetisch besonders befriedigender Gesamteindruck und eine einfache Handhabung. Ferner sind bei allen dargestellten AusfĆ¼hrungsformen Schienen, Klips, Rastmittel oder andere zusƤtzliche Befestigungsmittel obsolet. Durch die Kombination von Magnethalterung und Wippmechanismus ist eine besonders bedienerfreundliche Gestaltung von Dunstabzugshauben mƶglich.The Figs. 8A and 8B show a second embodiment of a filter element, which can be used in an extractor hood conventional design or in hoods of the above-described embodiments. The Fig. 8A shows a perspective view of the filter element 17. In this case, the filter element 17 has a cutout, which serves as a handling flap. The cutout 18 is, as in the Fig. 8A shown, closed in normal operation. In the Fig. 8B the filter element 3 is indicated in the installed and removable state. The upper illustration of the Fig. 8A shows the filter element 17 as it is held by a magnet, which is arranged inside the housing 9. The handling flap or cover 18 thus terminates flush with the remaining surface of the filter element 3. However, the handling flap can be opened via a rocking mechanism. This is in the Fig. 8B shown below. By a pressure in the direction of the arrow in the direction R to the housing interior 9 back, an engagement 19 can be released, so that the filter element 3 by hand, the magnetic force of the magnet or the magnet 11 overcoming, removable. In this case, not the complete filter element is rotatable about a rocking axis, but the filter element comprises a portion with a rocker or rotation axis 10 to release the engagement 19. Also in the embodiment of the Fig. 8 results in an aesthetically pleasing overall impression and easy handling. Furthermore, rails, clips, locking means or other additional fastening means are obsolete in all the illustrated embodiments. The combination of magnet holder and rocker mechanism enables a particularly user-friendly design of cooker hoods.
