Description

Bei Dunstabzugsvorrichtungen, die in die Raumdecke integriert werden und auch als DeckenlĆ¼fter bezeichnet werden, ist das GeblƤse oberhalb eines DunstabzugsgehƤuses angeordnet. Das GeblƤse ist in einem LĆ¼fterkasten montiert, dessen Luftauslass in der Regel in einer Seite des LĆ¼fterkastens vorgesehen ist. Der LĆ¼fterkasten ist in der Regel eckig und weist die Form einer Box auf. An den Luftauslass kƶnnen Rohrsysteme angeschlossen werden, Ć¼ber die die durch die Dunstabzugsvorrichtung angesaugte Luft abtransportiert werden kann. Da es aufgrund der baulichen Gegebenheiten um den Ort, an dem die Dunstabzugsvorrichtung in die Raumdecke integriert werden soll, notwendig sein kann den Luftauslass beispielsweise auf der linken oder der rechten Seite des LĆ¼fterkastens vorzusehen, muss der LĆ¼fterkasten mit dem darin befestigten GeblƤse bei der Montage der Dunstabzugsvorrichtung in der Regel demontiert und gedreht werden. Hierbei mĆ¼ssen auch die Kabelverbindungen oder Steckverbindungen gelƶst werden, und nach dem Positionieren des LĆ¼fterkastens, gegebenenfalls unter VerlƤngerung der Kabel verbunden werden.In extractor devices, which are integrated into the ceiling and are also referred to as ceiling fans, the fan is located above a fume hood housing. The fan is mounted in a fan box, the air outlet is usually provided in one side of the fan box. The fan box is usually square and has the shape of a box. At the air outlet pipe systems can be connected, via which the suctioned through the extractor air can be removed. Since it may be necessary to provide the air outlet, for example, on the left or the right side of the fan box due to the structural conditions around the place where the extractor device is to be integrated into the ceiling, the fan box with the fan mounted therein in the assembly of the Extractor device usually dismantled and rotated. In this case, the cable connections or connectors must be solved, and connected after positioning the fan box, possibly with extension of the cable.

Als LĆ¼ftergehƤuse wird dabei das GehƤuse bezeichnet, in dem zumindest das oder die LĆ¼fterrƤder des LĆ¼fters aufgenommen sind. Das LĆ¼ftergehƤuse umgibt das oder die LĆ¼fterrƤder eng. Das LĆ¼ftergehƤuse lenkt dabei die von dem LĆ¼fter abgegebene Luft zu einer Luftauslassƶffnung. Weiterhin weist das LĆ¼ftergehƤuse mindestens eine Lufteinlassƶffnung auf, Ć¼ber die Luft in das LĆ¼ftergehƤuse eintreten kann. ErfindungsgemƤƟ ist es aber auch mƶglich, dass in dem LĆ¼ftergehƤuse ein GeblƤse, beispielsweise ein SpiralgeblƤse aufgenommen ist. Bei dieser AusfĆ¼hrungsform besteht das GeblƤse aus einem LĆ¼fter und einem GeblƤsegehƤuse. Das LĆ¼ftergehƤuse umgibt bei dieser AusfĆ¼hrungsform das GeblƤsegehƤuse und kann beispielsweise die Form einer Kuppel aufweisen. Bei dieser AusfĆ¼hrungsform wird das GeblƤse von oben auf dem DunstabzugsgehƤuse befestigt und das LĆ¼ftergehƤuse wird Ć¼ber das GeblƤse gesetzt und beispielsweise Ć¼ber Langlƶcher drehbar auf das DunstabzugsgehƤuse aufgesetzt.As a vapor extraction housing, a housing is referred to, in which at least one filter element is held and which forms a suction chamber. In the extractor housing, the air purified through filters is directed to a fan of the extractor device. The fan is used in the extractor device to generate a negative pressure in order to suck in fumes and vapor in the extractor device and in particular in the extractor housing. The fan is at least partially accommodated in a fan housing. As fan housing while the housing is referred to, in which at least one or the fan wheels of the fan are added. The fan housing closely surrounds the fan or wheels. The fan housing directs the air discharged from the fan to an air outlet. Furthermore, the fan housing has at least one air inlet opening, via which air can enter the fan housing. However, according to the invention it is also possible for a fan, for example a spiral fan, to be accommodated in the fan housing. In this embodiment, the fan consists of a fan and a blower housing. The fan housing surrounds the fan housing in this embodiment and may for example have the shape of a dome. In this embodiment, the fan from the top of the extractor housing attached and the fan housing is placed over the fan and rotatably mounted, for example on slots on the extractor housing.

Die Dunstabzugsvorrichtung ist dadurch gekennzeichnet, dass der LĆ¼fter an dem DunstabzugsgehƤuse befestigt ist und das LĆ¼ftergehƤuse separat zu dem LĆ¼fter an dem DunstabzugsgehƤuse befestigt ist. Der LĆ¼fter kann beispielsweise an dem DunstabzugsgehƤuse angeschraubt oder damit verrastet werden. Insbesondere wird der LĆ¼fter vorzugsweise an der Innenseite der oberen Wand des DunstabzugsgehƤuses befestigt. Bei einem DeckenlĆ¼fter wird der LĆ¼fter daher vorzugsweise an der Unterseite der oberen Wand des DunstabzugsgehƤuses befestigt.The extractor device is characterized in that the fan is attached to the extractor housing and the fan housing is attached separately to the fan on the extractor housing. The fan can for example be screwed to the extractor housing or locked it. In particular, the fan is preferably attached to the inside of the upper wall of the extractor housing. In a ceiling fan, the fan is therefore preferably attached to the underside of the upper wall of the extractor housing.

Richtungsangaben, wie oben, unten sowie Angaben, wie Oberseite und Unterseite beziehen sich, sofern nicht anders angegeben auf die Dunstabzugsvorrichtung und deren Bauteile im montierten Zustand, insbesondere in einem in einer Raumdecke montierten Zustand.Directional information, as above, below as well as information, such as top and bottom refer, unless otherwise indicated on the extractor device and its components in the assembled state, especially in a mounted in a ceiling condition.

Das LĆ¼ftergehƤuse wird an dem DunstabzugsgehƤuse vorzugsweise durch Kraftschluss befestigt. Das LĆ¼ftergehƤuse wird dabei vorzugsweise ebenfalls an der Oberseite des DunstabzugsgehƤuses, das heiƟt an der oberen Wand des DunstabzugsgehƤuses befestigt. Besonders bevorzugt wird das LĆ¼ftergehƤuse zumindest bereichsweise an der Innenseite der oberen Wand des DunstabzugsgehƤuses befestigt. Bei einem DeckenlĆ¼fter wird das LĆ¼ftergehƤuse daher vorzugsweise an der Unterseite der oberen Wand des DunstabzugsgehƤuses befestigt.The fan housing is attached to the extractor housing preferably by frictional connection. The fan housing is preferably also attached to the top of the extractor housing, that is, on the upper wall of the extractor housing. Particularly preferably, the fan housing is at least partially secured to the inside of the upper wall of the extractor housing. In a ceiling fan, the fan housing is therefore preferably attached to the underside of the upper wall of the extractor housing.

Als separat befestigt werden ein LĆ¼ftergehƤuse und ein LĆ¼fter bezeichnet, die jeweils eine eigene Verbindung mit dem DunstabzugsgehƤuse aufweisen. Eine Befestigung des LĆ¼fters an dem DunstabzugsgehƤuse Ć¼ber das beziehungsweise mittels des LĆ¼ftergehƤuses, stellt somit keine separate Befestigung dar.As separately fastened a fan housing and a fan are designated, each having its own connection to the extractor housing. An attachment of the fan to the extractor housing via or by means of the fan housing, thus does not constitute a separate attachment.

Indem erfindungsgemƤƟ der LĆ¼fter separat zu dem LĆ¼ftergehƤuse an dem DunstabzugsgehƤuse befestigt wird, kann eine Reihe von Vorteilen erzielt werden. Zum einen kann beispielsweise bei der Montage der Dunstabzugsvorrichtung eine Bewegung des LĆ¼fters oder des LĆ¼ftergehƤuses vorgenommen werden, ohne, dass auch das jeweils andere Bauteil bewegt werden mĆ¼sste. Zudem ist es auch mƶglich die beiden Bauteile, LĆ¼fter und LĆ¼ftergehƤuse, nacheinander an dem DunstabzugsgehƤuse zu befestigen. Hierdurch kann beispielsweise zuerst das LĆ¼ftergehƤuse an dem DunstabzugsgehƤuse befestigt werden und nach der gewĆ¼nschten Positionierung des LĆ¼ftergehƤuses der LĆ¼fter befestigt werden. Ein Verdrehen oder Verkanten der Verkabelung, wie dies im Stand der Technik zu befĆ¼rchten ist, bei dem der LĆ¼fter an dem LĆ¼ftergehƤuse befestigt ist, ist bei der erfindungsgemƤƟen Dunstabzugsvorrichtung nicht zu befĆ¼rchten.By according to the invention, the fan is attached separately to the fan housing to the extractor housing, a number of advantages can be achieved. On the one hand, for example, during the assembly of the extractor device, a movement of the fan or the fan housing are made without that also the respective other component would have to be moved. In addition, it is also possible the two components, fans and Fan housing to attach one after the other to the extractor housing. As a result, for example, first the fan housing can be attached to the extractor housing and attached to the desired positioning of the fan housing of the fan. A twisting or tilting of the wiring, as is to be feared in the prior art, in which the fan is attached to the fan housing, is not to be feared in the extractor device according to the invention.

GemƤƟ einer bevorzugten AusfĆ¼hrungsform liegen der LĆ¼fter und das LĆ¼ftergehƤuse zumindest bereichsweise an gegenĆ¼berliegenden Seiten einer Wand des DunstabzugsgehƤuses an. Die Wand, an der die Bauteile befestigt werden, stellt vorzugsweise die Deckwand, das heiƟt obere Wand, des DunstabzugsgehƤuses, insbesondere den Boden einer nach unten offenen Wanne, dar. Vorzugsweise liegt das LĆ¼ftergehƤuse an der Oberseite der Deckwand und erstreckt sich zumindest bereichsweise zu der Unterseite der Deckwand. Der LĆ¼fter ist dabei vorzugsweise an der Unterseite der Wand befestigt und erstreckt sich Ć¼ber die Ebene der Deckwand nach oben. Das DunstabzugsgehƤuse weist hierbei eine Durchlassƶffnung auf, durch die zumindest ein Teil des LĆ¼fters, insbesondere das LĆ¼fterrad hindurch und in das LĆ¼ftergehƤuse gefĆ¼hrt werden kann. Der Teil des LĆ¼fters, der an der Unterseite der Deckwand des DunstabzugsgehƤuses anliegt und Ć¼ber den der LĆ¼fter mit der Unterseite der Deckwand verbunden werden kann, stellt insbesondere einen Befestigungsring dar, der den Motor und das LĆ¼fterrad trƤgt. Indem beispielsweise das LĆ¼ftergehƤuse an der Oberseite der Deckwand des DunstabzugsgehƤuses anliegt und der LĆ¼fter an der Unterseite befestigt ist, kann der LĆ¼fter zu Reparaturzwecken von unten aus dem LĆ¼ftergehƤuse entnommen werden, ohne das LĆ¼ftergehƤuse ebenfalls demontieren zu mĆ¼ssen.According to a preferred embodiment, the fan and the fan housing are at least partially on opposite sides of a wall of the extractor housing. The wall to which the components are attached, preferably the top wall, that is upper wall, the extractor housing, in particular the bottom of a downwardly open trough, is. Preferably, the fan housing is located at the top of the top wall and extends at least partially to the Bottom of the top wall. The fan is preferably attached to the underside of the wall and extends over the plane of the top wall upwards. The extractor housing in this case has a passage opening through which at least a part of the fan, in particular the fan wheel can be guided through and into the fan housing. The part of the fan, which bears against the underside of the top wall of the extractor housing and over which the fan can be connected to the underside of the top wall, in particular represents a mounting ring, which carries the motor and the fan. For example, by the fan housing rests on the top of the top wall of the extractor housing and the fan is attached to the bottom, the fan can be removed for repair purposes from below from the fan housing without having to dismantle the fan housing.

ErfindungsgemƤƟ weisen das LĆ¼ftergehƤuse und das DunstabzugsgehƤuse jeweils Befestigungsmittel auf. Als Befestigungsmittel werden hierbei Teile der GehƤuse bezeichnet, Ć¼ber die die beiden GehƤuse miteinander in Kontakt gebracht werden und Ć¼ber die zumindest eine Vorfixierung der relativen Position der beiden GehƤuse zueinander erfolgen kann. Vorzugsweise sind die Befestigungsmittel zumindest bereichsweise kreisfƶrmig. Die Befestigungsmittel kƶnnen insbesondere eine Durchlassƶffnung und einen Stutzen zum Eingreifen in die Durchlassƶffnung umfassen. Besonders bevorzugt umfassen die Befestigungsmittel weiterhin zumindest ein Befestigungselement. Die Befestigungselemente kƶnnen beispielsweise VorsprĆ¼nge und Aussparungen sein, die miteinander eingreifen kƶnnen. ErfindungsgemƤƟ sind die Befestigungsmittel zumindest bereichsweise kreisfƶrmig. Als zumindest bereichsweise kreisfƶrmig werden Befestigungsmittel bezeichnet, die entweder Befestigungselemente, wie kreisbogenfƶrmige Langlƶcher, aufweisen oder bei denen die Befestigungselemente an Bereichen, wie beispielsweise Durchlassƶffnungen oder Rohrstutzen Ć¼ber den Umfang der kreisfƶrmigen Bereiche verteilt angeordnet sind.According to the invention, the fan housing and the extractor housing each have fastening means. In this case, parts of the housing are designated as fastening means, via which the two housings are brought into contact with one another and via which at least one prefixing of the relative position of the two housings can take place relative to one another. Preferably, the fastening means are at least partially circular. The fastening means may in particular comprise a passage opening and a socket for engagement in the passage opening. Particularly preferably, the fastening means further comprise at least one fastening element. The fasteners may be, for example, projections and recesses which engage with each other can. According to the invention, the fastening means are at least partially circular. As at least partially circular fastening means are referred to, either fastening elements, such as circular arcuate slots, or in which the fastening elements are distributed to areas such as openings or pipe sockets over the circumference of the circular areas.

Indem die Befestigungsmittel zumindest teilweise kreisfƶrmig ausgestaltet sind, wird der Vorteil erzielt, dass das LĆ¼ftergehƤuse bezĆ¼glich des DunstabzugsgehƤuses verdreht werden kann, ohne, dass die Verbindung zwischen den beiden GehƤusen vollstƤndig aufgehoben werden muss.By the fastening means are at least partially circular, the advantage is achieved that the fan housing with respect to the extractor housing can be rotated without that the connection between the two housings must be completely canceled.

ErfindungsgemƤƟ liegen die Befestigungsmittel an dem LĆ¼ftergehƤuse im Bereich der Einlassƶffnung des LĆ¼ftergehƤuses. Im Bereich der Einlassƶffnung befinden sich Befestigungsmittel gemƤƟ dieser AusfĆ¼hrungsform, wenn die Befestigungsmittel neben der Einlassƶffnung, das heiƟt von der Einlassƶffnung aus nach auƟen versetzt liegen. Aber auch Befestigungselemente, die zu der Einlassƶffnung beispielsweise nach unten versetzt angeordnet sind, werden als im Bereich der Einlassƶffnung bezeichnet, sofern diese Befestigungsmittel eine Verbindung zu der Einlassƶffnung aufweisen. Beispielsweise kann das Befestigungsmittel hierbei ein sich von der Einlassƶffnung nach unten erstreckender rohrfƶrmiger Ɯberstand oder Rohrstutzen bezeichnet werden, an dem an der AuƟenseite Befestigungselemente beispielsweise BajonettvorsprĆ¼nge angeordnet sind.According to the invention, the fastening means are located on the fan housing in the region of the inlet opening of the fan housing. In the region of the inlet opening are fastening means according to this embodiment, when the fastening means next to the inlet opening, that are offset from the inlet opening to the outside. But also fasteners which are arranged offset to the inlet opening, for example, downward, are referred to as in the region of the inlet opening, provided that these fastening means have a connection to the inlet opening. By way of example, the fastening means may here be a tubular projection or pipe socket extending downwards from the inlet opening, on which fastening elements, for example bayonet projections, are arranged on the outside.

ErfindungsgemƤƟ liegen zudem an dem DunstabzugsgehƤuse die Befestigungsmittel im Bereich einer Durchlassƶffnung in dem DunstabzugsgehƤuses. Die Durchlassƶffnung weist hierbei erfindungsgemƤƟ Abmessungen auf, die der Einlassƶffnung des LĆ¼ftergehƤuses entsprechen. Insbesondere ist die Durchlassƶffnung so dimensioniert, dass zumindest die Befestigungsmittel des LĆ¼ftergehƤuses, insbesondere ein Rohrstutzen mit BajonettvorsprĆ¼ngen durch die Durchlassƶffnung gefĆ¼hrt werden kann und an deren Rand anliegt. Die Befestigungsmittel des DunstabzugsgehƤuses werden hierbei vorzugsweise durch die Durchlassƶffnung selber und durch Befestigungselemente, wie Aussparungen, insbesondere Bajonettaussparungen, an dem Umfang der Durchlassƶffnung realisiert.According to the invention are also on the extractor housing, the fastening means in the region of a passage opening in the extractor housing. The passage opening in this case according to the invention has dimensions which correspond to the inlet opening of the fan housing. In particular, the passage opening is dimensioned so that at least the fastening means of the fan housing, in particular a pipe socket with bayonet projections can be guided through the passage opening and bears against its edge. The fastening means of the extractor housing are hereby preferably realized by the passage opening itself and by fastening elements, such as recesses, in particular bayonet recesses, on the circumference of the passage opening.

Durch die Anordnung der Befestigungsmittel im Bereich der Einlassƶffnung und der Durchlassƶffnung kann die Verbindung zwischen den beiden GehƤusen in der NƤhe dieser Ɩffnungen oder an diesen Ɩffnungen erfolgen. Hierdurch wird der Vorteil erzielt, dass das Innere des LĆ¼ftergehƤuses durch die Durchlassƶffnung zugƤnglich ist und so insbesondere der LĆ¼fter durch die Durchlassƶffnung und die Einlassƶffnung in das LĆ¼ftergehƤuse gefĆ¼hrt werden kann.The arrangement of the fastening means in the region of the inlet opening and the passage opening, the connection between the two housings in the vicinity of these openings or at these openings can take place. In this way, the advantage is achieved that the interior of the fan housing is accessible through the passage opening and thus in particular the fan can be guided through the passage opening and the inlet opening in the fan housing.

GemƤƟ einer bevorzugten AusfĆ¼hrungsform steht die Achse des LĆ¼fters senkrecht zu der Oberseite des DunstabzugsgehƤuses. Als Achse des LĆ¼fters wird die Achse des LĆ¼fterrades bezeichnet. Durch diese Ausrichtung des LĆ¼fters kann die Einlassƶffnung des LĆ¼ftergehƤuses in der Verbindungsebene mit dem DunstabzugsgehƤuse liegen.According to a preferred embodiment, the axis of the fan is perpendicular to the top of the extractor housing. The axis of the fan is the axis of the fan wheel. Due to this orientation of the fan, the inlet opening of the fan housing can lie in the connection plane with the extractor housing.

Vorzugsweise steht die Achse des LĆ¼fters zentral in der Einlassƶffnung des LĆ¼ftergehƤuses. Diese AusfĆ¼hrungsform weist den Vorteil auf, dass ein Verdrehen des LĆ¼fters nicht zu einem Verschieben des LĆ¼fters bezĆ¼glich der Einlassƶffnung fĆ¼hrt.Preferably, the axis of the fan is centrally located in the inlet opening of the fan housing. This embodiment has the advantage that a rotation of the fan does not lead to a displacement of the fan with respect to the inlet opening.

Die Luftauslassƶffnung des LĆ¼ftergehƤuses ist erfindungsgemƤƟ in einer Seite des LĆ¼ftergehƤuses vorgesehen. Als Seite wird die Seitenwand des LĆ¼ftergehƤuses bezeichnet. Ist die Seitenwand eine gekrĆ¼mmte Wand, so liegt die Luftauslassƶffnung in dem Umfang der Seitenwand an einer Position. Indem die Luftauslassƶffnung in der Seite des LĆ¼ftergehƤuses vorgesehen ist, kann durch Drehen des LĆ¼ftergehƤuses um die Achse des LĆ¼fters die Richtung des Luftauslasses verƤndert und damit den baulichen Gegebenheiten angepasst werden.The air outlet opening of the fan housing is provided according to the invention in one side of the fan housing. The page refers to the side wall of the fan housing. If the side wall is a curved wall, the air outlet opening lies in a position in the circumference of the side wall. By the air outlet opening is provided in the side of the fan housing, by turning the fan housing about the axis of the fan, the direction of the air outlet can be changed and thus adapted to the structural conditions.

Das LĆ¼ftergehƤuse stellt vorzugsweise ein SpiralgehƤuse dar. Besonders bevorzugt bilden der LĆ¼fter und das LĆ¼ftergehƤuse hierbei ein einseitig ansaugendes SpiralgeblƤse. Die Einlassƶffnung liegt hierbei in der Durchlassƶffnung des DunstabzugsgehƤuses und die Luftauslassƶffnung liegt senkrecht zu der Einlassƶffnung.The fan housing preferably represents a spiral housing. Particularly preferably, the fan and the fan housing in this case form a unilaterally aspirated spiral fan. The inlet opening lies in the passage opening of the extractor housing and the air outlet opening is perpendicular to the inlet opening.

GemƤƟ eine bevorzugten AusfĆ¼hrungsform ist das LĆ¼ftergehƤuse zweiteilig und die Lufteinlassƶffnung ist in einem der GehƤuseteile eingebracht. Besonders bevorzugt ist die Lufteinlassƶffnung in einem unteren GehƤuseteil eingebracht, dass eine ebene Plattenform oder eine flache Schalenform aufweisen kann. Das obere GehƤuseteil weist vorzugsweise die Luftauslassƶffnung auf und bildet durch seine Form die Spiralform. Indem das LĆ¼ftergehƤuse zweiteilig aufgebaut ist, ist dessen Herstellung weiter vereinfacht, da keine Hinterschneidungen und dergleichen an den GehƤuseteilen ausgebildet sind und diese daher einfach, beispielsweise durch Spritzguss hergestellt werden kƶnnen.According to a preferred embodiment, the fan housing is in two parts and the air inlet opening is introduced into one of the housing parts. Particularly preferably, the air inlet opening is introduced into a lower housing part, which may have a flat plate shape or a flat shell shape. The upper housing part preferably has the air outlet opening and forms by its shape the spiral shape. while the fan housing is constructed in two parts, its manufacture is further simplified, since no undercuts and the like are formed on the housing parts and therefore easy, for example, can be made by injection molding.

Die Befestigungsmittel an dem DunstabzugsgehƤuse und dem LĆ¼ftergehƤuse umfassen vorzugsweise mindestens einen Bajonettvorsprung und/oder mindestens eine Bajonettaussparung. In einer alternativen AusfĆ¼hrungsform ist als Befestigungsmittel an dem DunstabzugsgehƤuse und/oder dem LĆ¼ftergehƤuse mindestens ein Langloch, das einen Kreisabschnitt beschreibt, vorgesehen. Bei dieser AusfĆ¼hrungsform kann das oder kƶnnen die Langlƶcher in einem ƤuƟeren Rand des LĆ¼ftergehƤuses vorgesehen sein. Alternativ kƶnnen die Langlƶcher aber auch in der Unterseite des LĆ¼ftergehƤuses eingebracht sein oder in der Oberseite des DunstabzugsgehƤuses. An dem jeweils anderen GehƤuse ist bei dieser AusfĆ¼hrungsform dann ein Vorsprung, beispielsweise durch eine Schraube vorgesehen, der in das Langloch eingreift und daher eine Drehbewegung der GehƤuse gegeneinander fĆ¼hrt. Durch Anziehen der Schraube oder anderes Verrasten des Vorsprungs kann dann die relative Endposition der beiden GehƤuse festgelegt werden und die beiden GehƤuse aneinander gehalten werden.The fastening means on the extractor housing and the fan housing preferably comprise at least one bayonet projection and / or at least one bayonet recess. In an alternative embodiment, at least one slot which describes a circular section is provided as a fastening means on the extractor housing and / or the fan housing. In this embodiment, the or the slots may be provided in an outer edge of the fan housing. Alternatively, the slots can also be introduced in the bottom of the fan housing or in the top of the extractor housing. At the respective other housing in this embodiment, a projection, for example, provided by a screw which engages in the slot and therefore a rotational movement of the housing leads against each other. By tightening the screw or other locking of the projection then the relative end position of the two housings can be determined and the two housings are held together.

GemƤƟ einer bevorzugten AusfĆ¼hrungsform stellt die Dunstabzugsvorrichtung einen DeckenlĆ¼fter dar. Besonders bevorzugt ist in der Unterseite des DunstabzugsgehƤuses mindestens ein Fettfilter lƶsbar befestigt. Als DeckenlĆ¼fter wird eine Dunstabzugsvorrichtung bezeichnet, bei der das DunstabzugsgehƤuse an den Seiten und von oben in einer Raumdecke aufgenommen ist. Bei dieser Art von Dunstabzugsvorrichtung kƶnnen die Vorteile der vorliegenden Erfindung besonders genutzt werden, da bei diesen Vorrichtungen die baulichen Gegebenheiten unterschiedlich sind und insbesondere die Position der Luftauslassƶffnung des LĆ¼ftergehƤuses entsprechend angepasst werden muss. Zudem kann bei dieser Art der Dunstabzugsvorrichtung der Vorteil genutzt werden, dass der LĆ¼fter nach der Montage der Dunstabzugsvorrichtung weiterhin von unten zugƤnglich ist, gegebenenfalls nach Entfernen der Fettfilter. Somit kƶnnen Wartungs- und Reparaturarbeiten an dem LĆ¼fter auch bei einem weiterhin in der Raumdecke integrierten DunstabzugsgehƤuses vorgenommen werden.According to a preferred embodiment, the extractor device is a ceiling fan. More preferably, at least one grease filter is releasably secured in the underside of the extractor housing. As a ceiling fan, a fume extraction device is referred to, in which the extractor housing is accommodated on the sides and from above in a room ceiling. In this type of extractor device, the advantages of the present invention can be used particularly because in these devices, the structural conditions are different and in particular the position of the air outlet opening of the fan housing must be adjusted accordingly. In addition, the advantage can be used in this type of extractor device that the fan after mounting the extractor device is still accessible from below, optionally after removing the grease filter. Thus, maintenance and repair work on the fan can be made even with a further integrated in the ceiling extractor housing.

The fastening means 1013 close to the edge of the air inlet opening 1010, that is, there forms a supernatant down. About this supernatant, the fan housing 10 can be introduced into the passage opening 110 extractor housing 11. In particular, the fastening means 1013 can be introduced into the passage opening 110 of the extractor housing 11 from above.

In der gezeigten AusfĆ¼hrungsform sind am unteren Ende des Ɯberstandes der Befestigungsmittel 1013 Ć¼ber den Umfang verteilt zwei Befestigungselemente 1014 in Form von BajonettvorsprĆ¼ngen 1011 vorgesehen, die sich radial nach auƟen erstrecken. Es kƶnnen auch abweichend von den zwei BajonettvorsprĆ¼ngen 1011 mehr als zwei oder nur ein Bajonettvorsprung 1011 vorgesehen sein.In the embodiment shown, two fastening elements 1014 in the form of bayonet projections 1011, which extend radially outward, are provided at the lower end of the projection of the fastening means 1013 distributed over the circumference. Deviating from the two bayonet projections 1011, more than two or only one bayonet projection 1011 may also be provided.

Da die Befestigungsmittel 1013, insbesondere der Ɯberstand an der Einlassƶffnung 1010 einen kreisfƶrmigen Querschnitt aufweist und der GrĆ¶ĆŸe der Durchlassƶffnung 110 in dem DunstabzugsgehƤuse 11 entspricht, kann das LĆ¼ftergehƤuse 10 mit in die Durchlassƶffnung 110 eingebrachten Befestigungsmittel 1013 um den Mittelpunkt der Lufteinlassƶffnung 1010 gedreht werden. Hierdurch verƤndert sich die Position der Luftauslassƶffnung 1000 des LĆ¼ftergehƤuses 10 und kann den baulichen Gegebenheiten angepasst werden.Since the fastening means 1013, in particular the projection on the inlet opening 1010, has a circular cross-section and corresponds to the size of the passage opening 110 in the extractor housing 11, the fan housing 10 can be rotated around the center of the air inlet opening 1010 with fastening means 1013 introduced into the passage opening 110. As a result, the position of the air outlet opening 1000 of the fan housing 10 changes and can be adapted to the structural conditions.

Ɯber den durch Bajonettvorsprung 1011 und Bajonettaussparung 111 gebildeten Bajonettverschluss ist das LĆ¼ftergehƤuse 10 an dem DunstabzugsgehƤuse 11 befestigt. ZusƤtzlich kann das LĆ¼ftergehƤuse 10 Ć¼ber Schrauben, die von unten von dem DunstabzugsgehƤuse 11 in der NƤhe der Durchlassƶffnung 11 nach oben eingebracht werden, endgĆ¼ltig fixiert werden.The fan housing 10 is fastened to the extractor housing 11 via the bayonet closure formed by the bayonet projection 1011 and the bayonet recess 111. In addition, the fan housing 10 can be finally fixed by means of screws introduced from below from the extractor housing 11 in the vicinity of the passage opening 11 upwards.

Nachdem das LĆ¼ftergehƤuse 10 an dem DunstabzugsgehƤuse 11 befestigt und gegebenenfalls endgĆ¼ltig fixiert ist, kann bei der vorliegenden Erfindung der LĆ¼fter 12 der Dunstabzugsvorrichtung 1 von unten in das LĆ¼ftergehƤuse 10 eingebracht werden. Hierbei wird von dem LĆ¼fter 12 lediglich das LĆ¼fterrad 120 (siehe Figur 7) in dem LĆ¼ftergehƤuse 10 aufgenommen. Die Befestigung des LĆ¼fters 12 und weitere Komponenten kƶnnen hingegen unterhalb des LĆ¼ftergehƤuses 10, insbesondere in dem DunstabzugsgehƤuse 11 liegen.After the fan housing 10 is attached to the extractor housing 11 and optionally permanently fixed, in the present invention, the fan 12 of the extractor device 1 can be introduced from below into the fan housing 10. Here, of the fan 12, only the fan 120 (see FIG. 7 ) received in the fan housing 10. The attachment of the fan 12 and other components, however, may be below the fan housing 10, in particular in the extractor housing 11.

Wie sich aus Figur 6 ergibt, weist der LĆ¼fter 12 an dessen Unterseite einen Befestigungsring 121 auf, Ć¼ber den der LĆ¼fter 12 von unten an der Deckwand 114 des DunstabzugsgehƤuses 11 befestigt werden kann. Insbesondere kann der LĆ¼fter 12 von unten in der NƤhe der Durchlassƶffnung 110 befestigt, beispielsweise angeschraubt, werden. Nach der Montage des LĆ¼fters 12 kƶnnen weitere Bestandteile der Dunstabzugsvorrichtung 1, wie insbesondere Filterelemente von unten in das DunstabzugsgehƤuse 11 eingebracht werden.As it turned out FIG. 6 results, the fan 12 has on the underside of a mounting ring 121, via which the fan 12 can be fixed from below to the top wall 114 of the extractor housing 11. In particular, the fan 12 can be fastened from below in the vicinity of the passage opening 110, for example screwed on. To the assembly of the fan 12, further components of the extractor device 1, in particular filter elements are introduced from below into the extractor housing 11.

Der LĆ¼fter ist bei dieser AusfĆ¼hrungsform Ć¼ber den Befestigungsring 121 an der Unterseite der Deckwand 114 befestigt und liegt somit an dieser Seite an. Das LĆ¼ftergehƤuse 10 hingegen liegt auf der Oberseite der Deckwand 114 an dem DunstabzugsgehƤuse 11 an. Durch den nach unten Ć¼berstehenden Ɯberstand und die BajonettvorsprĆ¼nge 1011, wird das LĆ¼ftergehƤuse 10 aber ebenfalls an der Unterseite der Deckwand 114 des DunstabzugsgehƤuses 11 befestigt.The fan is attached in this embodiment via the mounting ring 121 on the underside of the top wall 114 and thus lies on this side. The fan housing 10, however, is located on the top of the top wall 114 of the extractor housing 11. By the downwardly projecting projection and the bayonet projections 1011, the fan housing 10 but also attached to the underside of the top wall 114 of the extractor housing 11.

Figur 7 zeigt eine schematische Draufsicht auf das DunstabzugsgehƤuse 11 mit LĆ¼fter 12, wobei zur besseren Erkennbarkeit das LĆ¼ftergehƤuse nicht gezeigt ist. FIG. 7 shows a schematic plan view of the extractor housing 11 with fan 12, for better visibility, the fan housing is not shown.

Mit der vorliegenden Erfindung wird somit ein LĆ¼ftergehƤuse, das auch als LĆ¼fterkasten zeichnet werden kann, einer in die Decke integrierbaren Dunstabzugsvorrichtung, die auch als Dunstabzugshaube bezeichnet werden kann, mit anschlieƟbarem Rohrsystem geschaffen, bei der eine Drehbarkeit der Luftauslassƶffnung, die auch als Ausblasƶffnung bezeichnet werden kann, und damit der Anschluss eines Abluftschlauches in jede beliebige Raumrichtung 360Ā° ermƶglicht.With the present invention is thus a fan housing, which can also be characterized as a fan box, an integratable into the ceiling extractor device, which can also be referred to as extractor hood, created with connectable pipe system, in which a rotation of the air outlet, which are also referred to as a blowout allows, and thus the connection of an exhaust hose in any spatial direction 360 Ā°.

Bei der erfindungsgemƤƟen Dunstabzugsvorrichtung trƤgt das spiralfƶrmige LĆ¼ftergehƤuse keinen LĆ¼fter, der auch als GeblƤseeinheit bezeichnet werden kann. Das LĆ¼ftergehƤuse wird nur Ć¼ber den LĆ¼fter gesetzt, beziehungsweise der LĆ¼fter wird in das LĆ¼ftergehƤuse eingebracht und mit dem darunterliegenden DunstabzugsgehƤuse Ć¼ber Kraftschluss verbunden. Das LĆ¼ftergehƤuse ist also unabhƤngig von anderen Dunstabzugshaubenbauteilen drehbar. Das LĆ¼ftergehƤuse ist vorzugsweise zumindest bereichsweise runde und weist Befestigungsmittel auf, durch die eine Drehbewegung des LĆ¼ftergehƤuses ermƶglicht wird. Beispielsweise kƶnnen als Teil der Befestigungsmittel Langlƶcher, die sich Ć¼ber einen Kreisabschnitt erstrecken verwendet werden. In einer alternativen AusfĆ¼hrungsform wird ein Bajonettverschluss als Befestigungsmittel verwendet. Bei diesen AusfĆ¼hrungsformen ist eine einfache Drehung um den GeblƤsemittelpunkt, insbesondere um die Achse des LĆ¼fters um jeden beliebigen Winkel mƶglich.In the extractor device according to the invention, the spiral fan housing carries no fan, which can also be referred to as a fan unit. The fan housing is only placed over the fan, or the fan is placed in the fan housing and connected to the underlying extractor housing via traction. The fan housing is thus rotatable independently of other extractor hood components. The fan housing is preferably at least partially round and has fastening means by which a rotational movement of the fan housing is made possible. For example, elongated holes extending over a circular section can be used as part of the fastening means. In an alternative embodiment, a bayonet catch is used as the fastener. In these embodiments, a simple rotation about the fan center point, in particular around the axis of the fan at any angle is possible.

Die vorliegende Erfindung weist eine Reihe von Vorteilen auf. Insbesondere kann das LĆ¼ftergehƤuse sehr einfach ein Ausblasen in jede beliebige Richtung ermƶglichen. Zudem ist trotz der Verstellbarkeit der Ausblasƶffnung eine weitere Ƅnderung der Dunstabzugsvorrichtung, wie beispielsweise das Lƶsen von Kabelverbindungen, Steckverbindungen oder VerƤnderung der Lage von kabelfĆ¼hrenden Teilen nicht erforderlich.The present invention has a number of advantages. In particular, the fan housing can very easily allow blowing in any direction. In addition, despite the adjustability of the exhaust opening, a further change of the extractor device, such as the release of cable connections, connectors or changing the position of cable-carrying parts is not required.
