- the filter elements are held in a support frame that can be inserted into the extractor device. Due to the V-shaped arrangement of the filter elements in the filter unit, a larger filter surface, a better air flow and a better fat collection rate can be achieved. In addition, a lower back pressure is generated as a result.
- a disadvantage of this embodiment is that after the filter unit has been introduced into the suction opening of the fume extractor device, the filter elements are located below the suction opening.

- each of the frame parts preferably comprises at least part of the base of the support frame. As a result, the base parts of the two frame parts can be at least partially displaced on top of one another.
- the two base parts In the pushed together state, that is, in the removal position, the two base parts can lie completely on top of one another. In the pulled apart state, that is to say in the operating position, the base parts preferably continue to lie partially one above the other. Thus, even in the operating position, the base parts form a closed surface on which impurities can be collected.
- the frame parts are connected via a flexible connecting element.
- a connecting element that is elastically deformable is referred to as a flexible connecting element.
- a bellows can be used as the flexible connecting element.

The filter unit (1) is characterized in that the carrier frame (10) is designed to be movable in certain areas and the carrier frame (10) has at least one handle (12) through which at least one part of the carrier frame (10), in which one of the two filter elements (11) is arranged, can be moved.
Description
Die vorliegende Erfindung betrifft eine Filtereinheit für eine Dunstabzugsvorrichtung und eine Dunstabzugsvorrichtung mit mindestens einer Filtereinheit.The present invention relates to a filter unit for an extractor device and an extractor device with at least one filter unit.
Bei Dunstabzugsvorrichtungen, die zur Reinigung von verunreinigter Luft, insbesondere von Küchendünsten und Wrasen, verwendet werden, ist es bekannt, Filterelemente zu verwenden, durch die Fett und andere Verunreinigungen ausgefiltert werden. Die Filterelemente werden daher auch als Fettfilter bezeichnet.In the case of extractor devices that are used to clean polluted air, in particular kitchen fumes and vapors, it is known to use filter elements through which grease and other contaminants are filtered out. The filter elements are therefore also referred to as grease filters.
Bei Dunstabzugshauben, die in der Regel an einer Raumwand oder Raumdecke montiert werden und bei denen die verunreinigte Luft daher nach oben in die Dunstabzugshaube eingesaugt wird, wird das Filterelement so in die Ansaugöffnung eingebaut, dass diese die Fläche der Ansaugöffnung abdeckt.In the case of extractor hoods, which are usually mounted on a room wall or ceiling and where the polluted air is therefore sucked up into the extractor hood, the filter element is installed in the suction opening in such a way that it covers the area of the suction opening.
Bei Dunstabzugsvorrichtungen, die in oder neben einem Kochfeld installiert werden und die die verunreinigte Luft damit nach unten in die Dunstabzugsvorrichtung einsaugen, ist die zur Verfügung stehende Fläche für die Ansaugöffnung gering. Auch bei dieser Art von Dunstabzugsvorrichtung, die auch als Muldenlüfter oder Downdraft-Abzug bezeichnet werden kann, ist ebenfalls eine Verwendung von plattenförmigen Filterelementen bekannt. Um die Fläche des Filterelementes vergrößern zu können, ist es bekannt zwei Filterelemente zueinander in einem spitzen Winkel anzuordnen. Insbesondere bilden hierbei die Filterelemente eine V-Form. Die Filterelemente sind dabei in einem Trägerrahmen gehalten, der in die Dunstabzugsvorrichtung eingesetzt werden kann. Durch die V-förmige Anordnung der Filterelemente in der Filtereinheit kann eine größere Filterfläche, ein besserer Luftstrom und eine bessere Fettfangrate erzielt werden. Zudem wird hierdurch ein geringerer Gegendruck erzeugt.In the case of extractor devices that are installed in or next to a cooktop and thus suck the polluted air down into the extractor device, the area available for the suction opening is small. The use of plate-shaped filter elements is also known in this type of extractor device, which can also be referred to as a trough fan or downdraft extractor. In order to be able to enlarge the area of the filter element, it is known to arrange two filter elements at an acute angle to one another. In particular, the filter elements here form a V shape. The filter elements are held in a support frame that can be inserted into the extractor device. Due to the V-shaped arrangement of the filter elements in the filter unit, a larger filter surface, a better air flow and a better fat collection rate can be achieved. In addition, a lower back pressure is generated as a result.
Ein Nachteil dieser Ausführungsform besteht darin, dass die Filterelemente nach dem Einbringen der Filtereinheit in die Absaugöffnung der Dunstabzugsvorrichtung unterhalb der Absaugöffnung liegen. Hierdurch können Flüssigkeiten oder andere Verunreinigungen ungehindert zu den Filterelementen gelangen und diese damit verunreinigen, was dazu führt, dass die Filterelemente durch die Flüssigkeiten oder Verunreinigungen gesättigt werden und häufiger gereinigt werden müssen.A disadvantage of this embodiment is that after the filter unit has been introduced into the suction opening of the fume extractor device, the filter elements are located below the suction opening. This allows liquids or other contaminants to reach the filter elements unhindered and thus contaminate them, which in turn leads to the fact that the filter elements are saturated by the liquids or impurities and have to be cleaned more frequently.
Es ist daher Aufgabe der vorliegenden Erfindung eine Lösung zu schaffen, die auf einfache Weise die Nachteile des Standes der Technik zumindest mindert.It is therefore the object of the present invention to create a solution which at least reduces the disadvantages of the prior art in a simple manner.
Gemäß einem ersten Aspekt, wird diese Aufgabe gelöst durch eine Filtereinheit für eine Dunstabzugsvorrichtung, die zwei Filterelemente und mindestens einen Trägerrahmen für die Filterelement aufweist. Die Filtereinheit ist dadurch gekennzeichnet, dass der Trägerrahmen bereichsweise beweglich ausgebildet ist und der Trägerrahmen zumindest einen Griff aufweist, durch den zumindest ein Teil des Trägerrahmens, in dem eines der Filterelemente angeordnet ist, bewegt werden kann.According to a first aspect, this object is achieved by a filter unit for an extractor device, which has two filter elements and at least one support frame for the filter element. The filter unit is characterized in that the carrier frame is designed to be movable in certain areas and the carrier frame has at least one handle through which at least a part of the carrier frame in which one of the filter elements is arranged can be moved.
Als Filtereinheit für eine Dunstabzugsvorrichtung wird erfindungsgemäß eine bauliche Einheit bezeichnet, die in eine Ansaugöffnung der Dunstabzugsvorrichtung eingebracht werden kann und mittels derer die Luft von Verunreinigungen befreit werden kann. Zu diesem Zweck weist die Filtereinheit zwei Filterelemente auf. Jedes der Filterelemente stellt vorzugsweise ein längliches ebenes Element dar. Die Filterelemente können ebene Flächenelemente darstellen. Alternativ ist es allerdings auch möglich, dass das oder die Filterelemente gekrümmte Flächenelemente darstellen. Hierbei können die Filterelemente auch jeweils einen Halbkreis bilden. Bei zwei Filterelementen können diese zusammen eine Zylinderform bilden. Das Filterelement kann Filtermaterial aufweisen, das in einem Filterhalter, der auch als Filterrahmen bezeichnet werden kann, gehalten wird. Das Filtermaterial kann beispielsweise Streckmetalllagen, ein Vlies, ein Gestrick oder ein Gewirk sein. Insbesondere kann das Filtermaterial aus Draht bestehen. Zusätzlich zu den zwei Filterelementen weist die erfindungsgemäße Filtereinheit einen Trägerrahmen auf. Der Trägerrahmen dient zum Positionieren und Halten der Filterelemente beziehungsweise der Filterhalter in der Filtereinheit.According to the invention, a structural unit is referred to as a filter unit for an extractor device, which can be introduced into a suction opening of the extractor device and by means of which the air can be freed from impurities. For this purpose the filter unit has two filter elements. Each of the filter elements preferably represents an elongated flat element. The filter elements can represent flat surface elements.

If there are two filter elements, they can together form a cylinder shape. The filter element can have filter material that is held in a filter holder, which can also be referred to as a filter frame. The filter material can be, for example, expanded metal layers, a fleece, a knitted fabric or a knitted fabric. In particular, the filter material can consist of wire. In addition to the two filter elements, the filter unit according to the invention has a support frame. The support frame is used to position and hold the filter elements or the filter holder in the filter unit.
Der Trägerrahmen weist vorzugsweise einen Boden und zwei Seitenträger auf, die insbesondere die Stirnseiten des Trägerrahmens bilden, auf. Die Filterelemente und insbesondere die Filterhalter grenzen vorzugsweise an den Boden an. Die Seitenträger können sich vom Boden des Trägerrahmens und/oder von den Filterelementen, insbesondere den Filterhaltern aus erstrecken und bilden zumindest einen Teil der Stirnwand des Trägerrahmens.The support frame preferably has a base and two side supports, which in particular form the end faces of the support frame. The filter elements and in particular the filter holder preferably adjoin the floor. The side supports can protrude from the bottom of the support frame and / or from the filter elements, in particular extend from the filter holder and form at least part of the end wall of the support frame.
Richtungsangaben, wie oben und unten beziehen sich, soweit nicht anders angegeben auf die Filtereinheit und deren Komponenten in einem in eine horizontal ausgerichtete Ansaugöffnung einer Dunstabzugsvorrichtung, die Luft über die Ansaugöffnung nach unten einsaugt, eingebrachten Zustand. Die Filterelemente weisen vorzugsweise eine flächige Form auf und eine Abmessung der Fläche ist größer als die andere Abmessung der Fläche. Die längere Abmessung, wird als Länge des Filterelementes bezeichnet und die kürzere Abmessung als Höhe des Filterelementes. Die Filtereinheit ist vorzugsweise in eine Absaugöffnung eingebracht, die sich in Tiefenrichtung eines Kochfeldes erstreckt. Als Breite der Filtereinheit wird daher die Abmessung der Filtereinheit bezeichnet, die in der Breitenrichtung des Kochfeldes liegt. Bei einer anderen Ausrichtung der Absaugöffnung sind die Angaben entsprechen zu übertragen.Directional information such as above and below relate, unless otherwise stated, to the filter unit and its components in a state brought into a horizontally aligned suction opening of an extractor device that draws air in through the suction opening downwards. The filter elements preferably have a flat shape and one dimension of the area is larger than the other dimension of the area. The longer dimension is called the length of the filter element and the shorter dimension is the height of the filter element. The filter unit is preferably introduced into a suction opening which extends in the depth direction of a hob. The dimension of the filter unit which lies in the width direction of the hob is therefore referred to as the width of the filter unit. If the suction opening is oriented differently, the information must be transferred accordingly.
Die Filterelemente sind in dem Trägerrahmen vorzugsweise so aufgenommen, dass diese zu der Horizontalen nach unten geneigt liegen. Die Filterelemente können in der Senkrechten liegen. In dieser Ausführungsform liegen die Filterelemente parallel zueinander. Vorzugsweise sind die Filterelemente in dem Trägerrahmen aber so gehalten, dass diese zueinander geneigt sind. Insbesondere nimmt der Abstand der zwei Filterelemente zueinander von oben nach unten ab. Gemäß einer bevorzugten Ausführungsform liegen die Filterelemente zumindest in der Betriebsposition zueinander in einem spitzen Winkel.The filter elements are preferably received in the support frame in such a way that they are inclined downwards to the horizontal. The filter elements can be in the vertical. In this embodiment, the filter elements are parallel to one another. However, the filter elements are preferably held in the support frame in such a way that they are inclined to one another. In particular, the distance between the two filter elements decreases from top to bottom. According to a preferred embodiment, the filter elements are at an acute angle to one another, at least in the operating position.
Als Betriebsposition der Filterelemente wird deren Position bezeichnet, in der sich diese befinden, wenn die Filtereinheit in die Dunstabzugshaube eingebracht ist und die Dunstabzugsvorrichtung betrieben werden kann. Als Entnahmeposition wird die relative Position der Filterelemente zueinander bezeichnet, die diese in dem Zustand aufweisen, in dem die Filtereinheit aus der Absaugöffnung der Dunstabzugsvorrichtung entnommen oder in diese eingebracht werden kann.The operating position of the filter elements is the position in which they are located when the filter unit is inserted into the extractor hood and the extractor device can be operated. The relative position of the filter elements to one another is referred to as the removal position, which they have in the state in which the filter unit can be removed from the suction opening of the extractor device or introduced into it.
Erfindungsgemäß ist der Trägerrahmen bereichsweise beweglich ausgebildet. Als bereichsweise beweglich wird ein Trägerrahmen bezeichnet, bei dem zumindest ein Teil des Trägerrahmens relativ zu mindestens einem anderen Teil des Trägerrahmens beweglich gelagert ist.According to the invention, the support frame is designed to be movable in certain areas. A support frame in which at least one part of the support frame is movably mounted relative to at least one other part of the support frame.
Die Filtereinheit weist weiterhin einen Griff auf, durch den zumindest ein Teil des Trägerrahmens bewegt werden kann. In dem Teil des Trägerrahmens, der beweglich ausgebildet ist, ist eines der zwei Filterelemente angeordnet.The filter unit furthermore has a handle by means of which at least part of the support frame can be moved. One of the two filter elements is arranged in the part of the support frame which is designed to be movable.
Indem erfindungsgemäß an der Filtereinheit ein Griff vorgesehen ist, durch den zumindest ein Teil des Trägerrahmens, an dem eines der Filterelemente angeordnet ist, bewegt werden kann, kann die relative Position der Filterelemente zueinander durch Betätigung des Griffes verändert werden. Insbesondere kann zumindest der relative Abstand zwischen den beiden Filterelementen an deren oberen Rand verringert werden. Insbesondere kann der Trägerrahmen durch Betätigung des Griffs von einer Betriebsposition, die auch als Betriebsstellung bezeichnet werden kann, in eine Entnahmeposition, die auch als Entnahmestellung bezeichnet werden kann, gebracht werden. Mit der erfindungsgemäßen Filtereinheit ist es daher möglich, dass diese in der Betriebsposition eine größere Breite zumindest am oberen Rand aufweist als Breite der Absaugöffnung. Hierdurch liegt das oder liegen die Filterelemente zumindest bereichsweise unterhalb des Materials, in das die Absaugöffnung eingebracht wurde. Das Material ist vorzugsweise die Deckplatte eines Kochfeldes, die in der Regel aus Glas oder Glaskeramik besteht. Indem die relative Position der Filterelemente aber geändert werden kann, kann die Filtereinheit dennoch aus der Absaugöffnung entnommen werden. Hierzu wird der Trägerrahmen durch Betätigung des mindestens einen Griffes in eine Entnahmeposition gebracht, in dem zumindest der Abstand zwischen den oberen Rändern der Filterelemente geringer ist als in der Betriebsposition und insbesondere die Breite des Trägerrahmens geringer ist als die Breite der Absaugöffnung.Since, according to the invention, a handle is provided on the filter unit through which at least a part of the support frame on which one of the filter elements is arranged can be moved, the relative position of the filter elements to one another can be changed by actuating the handle. In particular, at least the relative distance between the two filter elements at their upper edge can be reduced. In particular, by actuating the handle, the carrier frame can be brought from an operating position, which can also be referred to as the operating position, into a removal position, which can also be referred to as the removal position. With the filter unit according to the invention it is therefore possible that in the operating position it has a greater width, at least at the upper edge, than the width of the suction opening. As a result, the filter element or elements are at least partially below the material into which the suction opening was made. The material is preferably the cover plate of a hob, which is usually made of glass or glass ceramic. However, since the relative position of the filter elements can be changed, the filter unit can still be removed from the suction opening. For this purpose, the support frame is brought into a removal position by operating the at least one handle, in which at least the distance between the upper edges of the filter elements is smaller than in the operating position and in particular the width of the support frame is smaller than the width of the suction opening.
Gemäß einer Ausführungsform weist die Filtereinheit einen Griff auf, durch den die zwei Filterelemente bewegt werden können. Bei dieser Ausführungsform ist der Griff somit mit beiden Filterelementen verbunden, das heißt kann auf diese einwirken. Das Einwirken kann mittelbar oder unmittelbar sein. Insbesondere kann zwischen dem Griff und dem Filterelement zumindest der Filterhalter des Filterelementes liegen. Zudem kann zwischen dem Griff und dem jeweiligen Filterelement ein Übertragungsmechanismus vorliegen. Der Übertragungsmechanismus dient zur Übertragung einer durch die Betätigung des Griffes hervorgerufenen Bewegung auf das jeweilige Filterelement. Dieser Übertragungsmechanismus kann mehrere Übertragungselemente umfassen. Beispielsweise können Schienen, Spindeln, Exzenter und dergleichen als Übertragungselemente verwendet werden. Der Griff ist bei der Ausführungsform der Filtereinheit, die nur einen Griff aufweist, vorzugsweise drehbar an der Filtereinheit und insbesondere an dem Rahmen gehalten.According to one embodiment, the filter unit has a handle by means of which the two filter elements can be moved. In this embodiment, the handle is thus connected to both filter elements, that is to say can act on them. The action can be direct or indirect. In particular, at least the filter holder of the filter element can be located between the handle and the filter element. In addition, a transmission mechanism can be present between the handle and the respective filter element. The transmission mechanism is used to transmit a through the operation of the handle caused movement on the respective filter element. This transmission mechanism can comprise several transmission elements. For example, rails, spindles, eccentrics and the like can be used as transmission elements. In the embodiment of the filter unit, which has only one handle, the handle is preferably rotatably held on the filter unit and in particular on the frame.
Ein Vorteil, der durch das Vorsehen nur eines Griffes, durch den die beiden Filterelemente bewegt werden können, erzielt werden kann, besteht darin, dass der Benutzer den Griff mit nur einer Hand betätigen kann.One advantage that can be achieved by providing only one handle by means of which the two filter elements can be moved is that the user can operate the handle with only one hand.
Gemäß einer bevorzugten Ausführungsform ist der mindestens eine Griff und vorzugsweise der nur eine Griff am Boden des Trägerrahmens angeordnet. Vorzugsweise erstreckt sich der Griff von dem Boden über zumindest einen Teil der Höhe des Trägerrahmens. Hierdurch kann der Griff am Boden angreifen und dort auf einen Übertragungsmechanismus einwirken und kann dennoch auf einfache Weise von oben vom Benutzer bedient werden. Vorzugsweise stellt der Griff hierbei einen Drehgriff dar. Als Drehgriff wird ein Griff bezeichnet, dessen Drehung auf einen Übertragungsmechanismus einwirkt und der gleichzeitig so ausgestaltet ist, dass der Benutzer, der an diesen Drehgriff angreift, die Filtereinheit an diesem Drehgriff hochheben oder in die Absaugöffnung absenken kann.According to a preferred embodiment, the at least one handle and preferably only one handle is arranged on the bottom of the support frame. Preferably, the handle extends from the floor over at least part of the height of the support frame. As a result, the handle can grip the ground and act there on a transmission mechanism and can nevertheless be operated in a simple manner by the user from above. The handle is preferably a rotary handle. A rotary handle is a handle whose rotation acts on a transmission mechanism and which is simultaneously designed so that the user who grips this rotary handle lifts the filter unit on this rotary handle or lowers it into the suction opening can.
Besonders bevorzugt weist der Griff zwei Endpositionen auf. In der einen Endposition liegen die Filterelemente zueinander in einer Betriebsposition und in einer anderen Endposition liegen die Filterelemente zueinander in einer Entnahmeposition. In einer oder beiden Endpositionen kann die aktuelle relative Position der Filterelemente zueinander fixiert werden.The handle particularly preferably has two end positions. In one end position, the filter elements are in an operating position with respect to one another and in another end position the filter elements are in a removal position with respect to one another. The current relative position of the filter elements to one another can be fixed in one or both end positions.
Gemäß einer alternativen Ausführungsform weist die Filtereinheit zwei Griffe auf. Bei dieser Ausführungsform wird durch jeden Griff ein Filterelement bewegt. Die Griffe sind vorzugsweise so angeordnet, dass diese mit einer Hand gegriffen werden können. Insbesondere liegen die Griffe daher in einem geringen Abstand zueinander, der von einer Hand überspannt werden kann. Die Griffe liegen dabei vorzugsweise auch in der Betriebsposition des Trägerrahmens in einem solchen geringen Abstand.According to an alternative embodiment, the filter unit has two handles. In this embodiment, a filter element is moved through each handle. The handles are preferably arranged so that they can be gripped with one hand. In particular, the handles are therefore at a small distance from one another, which can be spanned by one hand. The handles are preferably also in the operating position of the support frame at such a small distance.
Gemäß einer bevorzugten Ausführungsform sind die Filterelemente zueinander verschiebbar gelagert. Als zueinander verschiebbar gelagert werden Filterelemente bezeichnet, deren relative Position zueinander geändert werden kann. Die Filterelemente können daher so bewegt werden, dass der Abstand zwischen den Filterelementen vergrößert oder verkleinert wird. Bei dieser Ausführungsform kann die Neigung der Filterelemente in der Betriebsposition gleich deren Neigung in der Entnahmeposition sein. Beispielsweise können die Filterelement fest mit einem Übertragungselement eines Übertragungsmechanismus, der zwischen dem Griff und den Filterelementen liegt, verbunden sein. Es liegt aber auch im Rahmen der Erfindung, dass auch die Neigung der Filterelemente durch das Verschieben verändert wird.According to a preferred embodiment, the filter elements are mounted such that they can be moved relative to one another. Filter elements whose position relative to one another can be changed are referred to as being mounted so as to be displaceable relative to one another. The filter elements can therefore be moved in such a way that the distance between the filter elements is increased or decreased. In this embodiment, the inclination of the filter elements in the operating position can be the same as their inclination in the removal position. For example, the filter element can be firmly connected to a transmission element of a transmission mechanism that is located between the handle and the filter elements. However, it is also within the scope of the invention that the inclination of the filter elements is also changed by the displacement.
Gemäß einer bevorzugten Ausführungsform besteht der Trägerrahmen aus zwei Rahmenteilen. In jedem Rahmenteil ist bei dieser Ausführungsform eines der Filterelemente gehalten. Die Rahmenteile sind gemäß einer Ausführungsform über eine Schubführung miteinander verbunden. Die Schubführung kann eine Schienenführung darstellen. Alternativ kann die Schubführung beispielsweise eine Langloch-Stift-Führung sein, bei der ein Stift an einem Rahmenteil angeordnet ist und in ein Langloch, das in dem weiteren Rahmenteil vorgesehen ist, eingreift. Bei der zweiteiligen Ausführungsform, bei der die Rahmenteile über eine Schubführung miteinander verbunden sind, umfasst vorzugsweise jedes der Rahmenteile zumindest einen Teil des Bodens des Trägerrahmens. Hierdurch können die Bodenteile der beiden Rahmenteile zumindest teilweise aufeinander verschoben werden. Im zusammengeschobenen Zustand, das heißt in der Entnahmeposition können die beiden Bodenteile vollständig übereinander liegen. In dem auseinander gezogenen Zustand, das heißt in der Betriebsposition, liegen die Bodenteile vorzugsweise weiterhin teilweise übereinander. Somit wird auch in der Betriebsposition durch die Bodenteile eine geschlossene Fläche gebildet, auf der Verunreinigungen gesammelt werden können.According to a preferred embodiment, the support frame consists of two frame parts. In this embodiment, one of the filter elements is held in each frame part. According to one embodiment, the frame parts are connected to one another via a sliding guide. The push guide can represent a rail guide. Alternatively, the push guide can be, for example, an elongated hole pin guide in which a pin is arranged on a frame part and engages in an elongated hole provided in the further frame part. In the two-part embodiment, in which the frame parts are connected to one another via a sliding guide, each of the frame parts preferably comprises at least part of the base of the support frame. As a result, the base parts of the two frame parts can be at least partially displaced on top of one another. In the pushed together state, that is, in the removal position, the two base parts can lie completely on top of one another. In the pulled apart state, that is to say in the operating position, the base parts preferably continue to lie partially one above the other. Thus, even in the operating position, the base parts form a closed surface on which impurities can be collected.
Gemäß einer alternativen Ausführungsform sind bei einem zweiteiligen Trägerrahmen die Rahmenteile über ein flexibles Verbindungselement verbunden. Als flexibles Verbindungselement wird ein Verbindungselement bezeichnet, das elastisch verformbar ist. Beispielsweise kann als flexibles Verbindungselement ein Faltenbalg verwendet werden. Durch das Vorsehen eines flexiblen Verbindungselementes kann durch Zusammendrücken oder Auseinanderziehen des flexiblen Verbindungselementes der Abstand zwischen den beiden Rahmenteilen und damit zwischen den zwei Filterelementen verändert werden.According to an alternative embodiment, in the case of a two-part support frame, the frame parts are connected via a flexible connecting element. A connecting element that is elastically deformable is referred to as a flexible connecting element. For example, a bellows can be used as the flexible connecting element. By providing a flexible connecting element, Compressing or pulling apart the flexible connecting element, the distance between the two frame parts and thus between the two filter elements can be changed.
Sowohl die Schubführung als auch das flexible Verbindungselement können vorzugsweise jeweils in eine Richtung vorgespannt sein. Insbesondere sind die Schubführung und/oder das Verbindungselement jeweils so vorgespannt, dass diese in dem entspannten Zustand die beiden Rahmenteile auseinander drücken und insbesondere in die Betriebsposition bringen. Durch Angreifen und insbesondere Zusammendrücken der zwei Griffe, von denen jeweils einer an jedem Rahmenteil befestigt ist, kann der Benutzer eine Kraft auf die beiden Rahmenteile aufbringen, durch die die Schubführung beziehungsweise das Verbindungselement entgegen der Vorspannung zusammengedrückt wird. Indem die Schubführung oder das Verbindungselement vorzugsweise in Richtung der Betriebsposition vorgespannt ist, kann zuverlässig das korrekte Positionieren der Filterelemente in der Dunstabzugsvorrichtung sichergestellt werden.Both the push guide and the flexible connecting element can preferably each be prestressed in one direction. In particular, the thrust guide and / or the connecting element are each pretensioned in such a way that, in the relaxed state, they push the two frame parts apart and, in particular, bring them into the operating position. By grasping and in particular pressing together the two handles, one of which is attached to each frame part, the user can apply a force to the two frame parts by means of which the slide guide or the connecting element is pressed together against the bias. Since the push guide or the connecting element is preferably pretensioned in the direction of the operating position, the correct positioning of the filter elements in the extractor device can be reliably ensured.
Gemäß einer Ausführungsform sind die Filterelemente in der Filtereinheit schwenkbar gelagert. Insbesondere können die Filterelemente so gelagert sein, dass deren obere Ränder aufeinander zu und voneinander weg bewegt werden können. Die unteren Ränder können hingegen in einem festen Abstand zueinander liegen. Insbesondere können die unteren Ränder der Filterelemente an den Rändern eines Bodens des Trägerrahmens schwenkbar gelagert sein. Für das Verschwenken der Filterelemente können diese über ein Drehscharnier oder ein Filmscharnier mit dem Boden verbunden sein. Insbesondere werden die Filterelemente, die in einem Filterhalter gehalten sind, schwenkbar an dem Boden befestigt. Bei dieser Ausführungsform liegt das Drehscharnier oder das Filmscharnier zwischen dem Boden und dem Filterhalter.According to one embodiment, the filter elements are pivotably mounted in the filter unit. In particular, the filter elements can be mounted in such a way that their upper edges can be moved towards and away from one another. The lower edges, on the other hand, can be at a fixed distance from one another. In particular, the lower edges of the filter elements can be pivotably mounted on the edges of a base of the support frame. For pivoting the filter elements, they can be connected to the floor via a rotary hinge or a film hinge. In particular, the filter elements, which are held in a filter holder, are pivotably attached to the floor. In this embodiment, the rotary hinge or the film hinge lies between the base and the filter holder.
Gemäß einer Ausführungsform ist mindestens ein Griff an dem oberen Rand des Trägerrahmens angeordnet. Der Griff kann unmittelbar im oberen Rand des Trägerrahmens liegen oder kann zu dem oberen Rand um einen geringen Abstand nach unten versetzt angeordnet sein. Durch diese Anordnung ist der Griff oder sind die Griffe für den Benutzer leicht zu erreichen.According to one embodiment, at least one handle is arranged on the upper edge of the support frame. The handle can lie directly in the upper edge of the support frame or can be arranged offset downward by a small distance from the upper edge. This arrangement makes the handle or handles easy to reach for the user.
Gemäß einer bevorzugten Ausführungsform besteht der Trägerrahmen aus zwei Rahmenteilen und jedes Rahmenteil weist jeweils zwei Seitenträger. Als Seitenträger werden Teile des Trägerrahmens bezeichnet, die in einem Winkel, der ungleich Null ist, zu dem Boden liegen. Vorzugsweise liegen die Seitenträger an den Stirnseiten des Trägerrahmens. Gemäß einer Ausführungsform sind die Seitenträger an den Längsenden der Filterelemente und insbesondere der Filterhalter, in denen die Filterelemente jeweils gehalten sind, vorgesehen und stehen senkrecht zu dem Boden. Die Seitenträger können dabei die gesamten Stirnflächen des Trägerrahmens bilden. Alternativ können die Seitenträger aber auch so ausgestaltet sein, dass diese nur einen geringen Teil der Stirnfläche bilden. In diesem Fall können die Seitenträger beispielsweise eine dreieckige Fläche abdecken, von der eine Seitenfläche an dem Filterelement oder Filterhalter befestigt ist, und die zweite Seitenfläche in der Oberseite des Trägerrahmens liegt.According to a preferred embodiment, the support frame consists of two frame parts and each frame part has two side supports. Parts of the support frame that are at an angle that is not equal to zero to the floor are referred to as side supports. The side supports are preferably located on the end faces of the support frame. According to one embodiment, the side supports are provided on the longitudinal ends of the filter elements and in particular the filter holder in which the filter elements are each held and are perpendicular to the floor. The side supports can form the entire end faces of the support frame. Alternatively, however, the side supports can also be designed in such a way that they only form a small part of the end face. In this case, the side supports can cover a triangular surface, for example, of which one side surface is attached to the filter element or filter holder, and the second side surface lies in the upper side of the support frame.
An den zwei Seitenträgern eines Rahmenteils sind jeweils die Enden eines Griffes befestigt. Bei dieser Ausführungsform wird der Griff daher vorzugsweise durch ein längliches Element, beispielsweise eine Stange gebildet. An dem zweiten Rahmenteil ist einsprechend ein weiterer Griff befestigt. Vorzugsweise sind die Griffe in der Nähe des Endes des Seitenträgers angeordnet, das dem anderen Seitenträger zugewandt ist. Hierdurch ist der Abstand zwischen den Griffen gering und kann auf einfache Weise durch den Benutzer mit einer Hand gegriffen werden.The ends of a handle are attached to the two side supports of a frame part. In this embodiment, the handle is therefore preferably formed by an elongate element, for example a rod. A further handle is correspondingly attached to the second frame part. Preferably, the handles are located near the end of the side rail facing the other side rail. As a result, the distance between the handles is small and can be easily gripped by the user with one hand.
Gemäß einem weiteren Aspekt betrifft die Erfindung eine Dunstabzugsvorrichtung mit mindestens einer erfindungsgemäßen Filtereinheit.According to a further aspect, the invention relates to an extractor device with at least one filter unit according to the invention.
Vorteile und Merkmale, die bezüglich der Filtereinheit beschrieben wurden und werden, gelten entsprechend für die Dunstabzugsvorrichtung und umgekehrt und werden gegebenenfalls nur einmalig beschrieben.Advantages and features that have been and will be described with respect to the filter unit apply accordingly to the extractor hood device and vice versa and may only be described once.
Gemäß einer bevorzugten Ausführungsform weist die Dunstabzugsvorrichtung eine Ansaugöffnung und ein unterhalb der Ansaugöffnung angeordnetes Gebläse auf, das Luft über die Ansaugöffnung nach unten absaugt, und die Filtereinheit ist in die Ansaugöffnung eingeführt. Diese Art der Dunstabzugsvorrichtung wird auch als Downdraft-Abzug oder Muldenlüftung bezeichnet.According to a preferred embodiment, the fume extractor device has a suction opening and a fan arranged below the suction opening which sucks air downwards via the suction opening, and the filter unit is inserted into the suction opening. This type of extractor device is also known as a downdraft extractor or downdraft ventilation.

Bei dieser zweiten Ausführungsform kann der Benutzer durch Umgreifen der beiden Griffe die beiden Rahmenteile 100, 101 zueinander bewegen, das heißt zusammendrücken. Hierbei wird insbesondere der Abstand zwischen den oberen Rändern der Filterelemente 11, die geneigt in dem Trägerrahmen 10 gehalten sind, verringert. Ist der Abstand zwischen den oberen Rändern geringer als die Breite einer Absaugöffnung (nicht gezeigt) einer Dunstabzugsvorrichtung kann die Filtereinheit 1 in die Absaugöffnung eingebracht werden und aus dieser entnommen werden.In this second embodiment, the user can move the two
Lässt der Benutzer die Griffe 12 los, nachdem die Filtereinheit 1 in die Absaugöffnung eingebracht wurde, so expandiert das vorgespannte flexible Verbindungselement 105 und drückt somit die Rahmenteile 100, 101 auseinander. Hierdurch vergrößert sich der Abstand zwischen den oberen Rändern der Filterelemente 11 und diese liegen daher unterhalb der Fläche des Materials, in das die Absaugöffnung eingebracht ist.

Mit der vorliegenden Erfindung wird somit eine Lösung geschaffen, die ein zuverlässiges Einbringen und Entnehmen einer Filtereinheit in und aus einer Dunstabzugsvorrichtung erlaubt. Insbesondere wird kann eine einhändige Entnahme der Filtereinheit, die zumindest zwei Filterelemente aufweist, realisiert werden.With the present invention, a solution is thus created which allows a reliable introduction and removal of a filter unit into and out of an extractor device. In particular, the filter unit, which has at least two filter elements, can be removed with one hand.
Die neue Konstruktion der Filtereinheit erlaubt es aus Platzgründen und auch zur Verbesserung der Abdichtung der Luftführung, dass die Filterelemente unter der Glaskeramik, in der die Absaugöffnung eingebracht ist, liegen. In einer Ausführungsform wird die Filtereinheit durch Drehung eines Griffs oder Zusammenpressen zweier Griffstangen komprimiert. Eine Entnahme wird somit ermöglicht, dass die Filterelemente in der Betriebsstellung unter dem Glas liegen und dennoch durch die Absaugöffnung im Glas herausgenommen werden können. Die beiden Zustände könnten durch eine mechanische Verschiebung angezeigt werden. Zudem können die Zustände oder Stellungen der Filtereinheit durch Indikation durch Farbe und/oder Symbole angezeigt werden.For reasons of space and also to improve the sealing of the air duct, the new design of the filter unit allows the filter elements to be located under the glass ceramic in which the suction opening is made. In one embodiment, the filter unit is compressed by rotating a handle or pressing two handle bars together. Removal is thus made possible so that the filter elements lie under the glass in the operating position and can still be removed through the suction opening in the glass. The two states could be indicated by a mechanical shift. In addition, the states or Positions of the filter unit are indicated by color and / or symbols.
Der Benutzer kann mit einer Hand die beiden Filterelement der Filtereinheit auf einmal in einem Trägerrahmen entnehmen und reinigen. Durch das Verschieben, Klappen, Drehen der Filterelemente kann ein Arretieren und damit eine sichere und konkrete Positionierung der Filterelemente garantiert und angezeigt werden. Die korrekte Funktion der Dunstabzugsvorrichtung wird damit sichergestellt.The user can remove the two filter elements of the filter unit at once in a support frame and clean them with one hand. By moving, folding and rotating the filter elements, locking and thus safe and precise positioning of the filter elements can be guaranteed and displayed. This ensures that the extractor hood functions correctly.
