Der Erfindung stellt sich somit das Problem, eine Dunstabzugsvorrichtung der eingangs genannten Art zur Verfügung zu stellen, bei der die Mechanik, welche die Öffnungsbeziehungsweise Schließbewegung der Lamellen bewirkt, robuster und damit weniger verschleißanfällig ausgeführt ist.The invention thus raises the problem of providing a fume extractor of the type mentioned above, in which the mechanism which causes the opening relationship as closing movement of the fins, more robust and thus less susceptible to wear.
Erfindungsgemäß wird dieses Problem durch eine Dunstabzugsvorrichtung der eingangs genannten Art mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention this problem is solved by a fume extractor device of the type mentioned with the features of
Gemäß Anspruch 1 zeichnet sich eine erfindungsgemäße Dunstabzugsvorrichtung dadurch aus, dass die Dunstabzugsvorrichtung ein Ansaugpaneel umfasst, das mit der Absaugeinheit in Strömungsverbindung steht und innerhalb dessen die Lamellen im Wesentlichen parallel zueinander verschiebbar angeordnet sind. Die mit der Erfindung erreichbaren Vorteile bestehen insbesondere darin, dass die Lamellen nicht verschwenkbar, sondern im Wesentlichen parallel zueinander verschiebbar innerhalb des Ansaugpaneels angeordnet sind, so dass die Mechanik, welche die Öffnungs- beziehungsweise Schließbewegung der Lamellen bewirkt, robuster und damit weniger verschleißanfällig ausgeführt ist. Ferner ist mit der erfindungsgemäßen Mechanik eine weniger raumgreifende Dunstabzugsvorrichtung erzielt. Die im Wesentlichen parallel zueinander verschiebbaren Lamellen können in ihrer Gebrauchsstellung (Ansaugposition), in der sie die Ansaugfläche des Ansaugpaneels zumindest bereichsweise freigeben, in vorteilhafter Weise bewirken, dass die Kochdämpfe eine Vorzugsrichtung auf die Ansaugfläche der Dunstabzugsvorrichtung erhalten und somit nicht an der Ansaugfläche vorbeiströmen. Vorzugsweise sind die Lamellen innerhalb des Ansaugpaneels derart angeordnet und verschiebbar geführt, dass sie sich beim Überführen aus der Nichtgebrauchsstellung in die Gebrauchsstellung in einer kombinierten Bewegung sowohl orthogonal als auch parallel zu der Ansaugfläche des Ansaugpaneels 3 bewegen. Gleiches gilt für die Rücküberführung von der Gebrauchsstellung in die Nichtgebrauchsstellung. Vorzugsweise erfolgt die Bewegung der Lamellen gleichzeitig. Die erfindungsgemäße Dunstabzugsvorrichtung kann durch eine entsprechende strömungstechnische Ausgestaltung entweder für einen Abluftbetrieb oder für einen Umluftbetrieb eingerichtet sein.According to
In einer bevorzugten Ausführungsform wird vorgeschlagen, dass das Ansaugpaneel relativ zur Absaugeinheit aus einer Nichtgebrauchsstellung in eine Gebrauchsstellung verschwenkbar ist. Die Dunstabzugsvorrichtung kann insbesondere so ausgebildet sein, dass das Ansaugpaneel aus der Nichtgebrauchsstellung, in der das Ansaugpaneel vorzugsweise im Wesentlichen parallel zu einer ihm zugewandten Gehäusewand der Absaugeinheit orientiert ist, um einen bestimmten voreingestellten Winkel, der insbesondere in einem Bereich von etwa 40° bis etwa 45° liegen kann, relativ zur Absaugeinheit verschwenkt werden kann. Vorzugsweise weist die Dunstabzugsvorrichtung mehrere Scharnierbauteile auf, mittels derer das Ansaugpaneel schwenkbar gelagert ist. Die Scharnierbauteile können einerseits am Ansaugpaneel und andererseits am Gehäuse der Absaugeinheit und/oder an einem in einer Öffnung einer Wand montierbaren Wandeinbaurahmen angeordnet sein und nach der Montage derart zusammenwirken, dass das Ansaugpaneel relativ zur Absaugeinheit verschwenkt werden kann. Die Dunstabzugsvorrichtung kann eine Antriebsvorrichtung umfassen, die an das Ansaugpaneel angeschlossen ist und dazu geeignet ist, die Schwenkbewegung des Ansaugpaneels anzutreiben. Die Antriebsvorrichtung kann einen Motor und mindestens ein Kopplungsmittel aufweisen, das mit dem Motor in Wirkverbindung steht und mit dem Ansaugpaneel gekoppelt ist. Um den mechanischen Aufbau der Antriebsvorrichtung zu vereinfachen, kann das mindestens eine Kopplungsmittel zum Beispiel ein im Wesentlichen stangenförmiges Kopplungsteil umfassen. Andere äquivalente Kopplungsmittel können in weiteren alternativen Ausführungsformen ebenfalls verwendet werden. Der Motor, der zum Beispiel ein Linearmotor (vorzugsweise ein Spindeltrieb) sein kann, treibt eine Linearbewegung des Kopplungsmittels an, welches mit dem Ansaugpaneel gekoppelt ist und das schwenkbar gelagerte Ansaugpaneel aus der Nichtgebrauchsstellung in die Gebrauchsstellung drückt beziehungsweise aus der Gebrauchsstellung wieder in die Nichtgebrauchsstellung zieht.In a preferred embodiment, it is proposed that the intake panel can be pivoted relative to the suction unit from a non-use position into a use position. The extractor device may in particular be designed such that the suction panel from the non-use position, in which the suction panel is preferably oriented substantially parallel to a facing housing wall of the suction unit, by a certain preset angle, in particular in a range of about 40 ° to about Can be 45 °, can be pivoted relative to the suction unit. Preferably, the extractor device comprises a plurality of hinge components, by means of which the intake panel is pivotally mounted. The hinge components can be arranged on the intake panel on the one hand and on the housing of the suction unit and / or on a wall mounting frame which can be mounted in an opening of a wall and cooperate after assembly such that the suction panel can be pivoted relative to the suction unit. The extractor device may comprise a drive device which is connected to the suction panel and is adapted to drive the pivoting movement of the suction panel. The drive device may include a motor and at least one coupling means operatively connected to the engine and coupled to the intake panel. In order to simplify the mechanical construction of the drive device, the at least one coupling means may comprise, for example, a substantially rod-shaped coupling part. Other equivalent coupling agents may also be used in other alternative embodiments. The motor, which may be, for example, a linear motor (preferably a spindle drive), drives a linear movement of the coupling means, which is coupled to the Ansaugpaneel and presses the pivotally mounted intake panel from the non-use position in the use position or moves from the use position back to the non-use position ,
In einer besonders vorteilhaften Ausführungsform besteht die Möglichkeit, dass die Dunstabzugsvorrichtung eine Antriebsvorrichtung umfasst, die mit den Lamellen gekoppelt ist und dazu geeignet ist, die Verschiebebewegung der Lamellen anzutreiben.In a particularly advantageous embodiment, there is the possibility that the extractor device comprises a drive device which is coupled to the lamellae and is suitable for driving the displacement movement of the lamellae.
Um die Montage der Lamellen zu vereinfachen, sieht eine besonders bevorzugte Ausführungsform vor, dass die Dunstabzugsvorrichtung einen Lamellenhalter aufweist, an dem die Lamellen befestigt sind. Die Lamellen können an diesem Lamellenhalter vormontiert und ausgerichtet werden, der dann bei der Montage innerhalb des Ansaugpaneels angeordnet wird. Mit Hilfe des Lamellenhalters ist es möglich, die Lamellen so auszurichten, dass sie gemeinsam im Wesentlichen parallel zueinander verschoben werden können.In order to simplify the assembly of the slats, a particularly preferred embodiment provides that the extractor device has a slat holder to which the slats are attached. The slats can be pre-assembled and aligned on this slat holder, which is then arranged during assembly within the intake panel. With the help of the lamella holder, it is possible to align the lamellae so that they can be moved together substantially parallel to each other.
Um die Antriebsvorrichtung auf besonders einfache Weise mechanisch mit dem Lamellenhalter zu koppeln, besteht in einer bevorzugten Ausführungsform die Möglichkeit, dass die Antriebsvorrichtung mindestens einen Hebel aufweist, der sich zwischen der Antriebsvorrichtung und dem Lamellenhalter erstreckt. Die Antriebsvorrichtung kann in einer vorteilhaften Ausführungsform einen Getriebemotor umfassen. Um zum Beispiel ein Einquetschen der Finger eines Benutzers während der Bewegung der Lamellen zu verhindern und damit die Gefahr von Verletzungen zu verringern, kann der Getriebemotor beispielsweise so ausgeführt sein, dass er sich leistungsbedingt abschaltet. Alternativ kann der Getriebemotor zusätzlich eine Widerstandsschaltung umfassen, die bei einem mechanischen Widerstand ein Abschalten des Getriebemotors und damit einen Stop der Ausfahr- beziehungsweise Einfahrbewegungen der Lamellen bewirken kann.To couple the drive device in a particularly simple manner mechanically with the lamella holder, in a preferred embodiment, there is the possibility that the drive device has at least one lever which extends between the drive device and the lamella holder. The drive device may comprise a geared motor in an advantageous embodiment. For example, to prevent squeezing the fingers of a user during the movement of the slats and thus reduce the risk of injury, the geared motor, for example, be designed so that it switches off due to performance. Alternatively, the gear motor may additionally comprise a resistance circuit, which can cause a shutdown of the gear motor and thus a stop of the extension or retraction movements of the slats in a mechanical resistance.
Es kann in einer besonders bevorzugten Ausführungsform vorgesehen sein, dass der Getriebemotor eine drehbare Welle aufweist, an der ein im Wesentlichen scheibenförmiges Element befestigt ist, an dem der Hebel exzentrisch drehbar angebracht ist. Der Hebel kann insbesondere drehbeweglich am Lamellenhalter angebracht sein. Dadurch ist es möglich, die Drehbewegung des im Wesentlichen scheibenförmigen Elements in eine Verschiebebewegung des Lamellenhalters in einer Ebene innerhalb des Ansaugpaneels umzusetzen und so die Parallelverschiebung der Lamellen in die Gebrauchsstellung beziehungsweise zurück in die Nichtgebrauchsstellung zu bewirken. Im Inneren des Ansaugpaneels kann in einer vorteilhaften Ausführungsform darüber hinaus zumindest eine erste Schwenklasche schwenkbar angeordnet sein, die gelenkig mit dem Lamellenhalter verbunden ist. Ferner kann im Inneren des Ansaugpaneels eine zweite Schwenklasche schwenkbar angeordnet sein, die gelenkig mit dem Lamellenhalter verbunden ist.It may be provided in a particularly preferred embodiment that the geared motor has a rotatable shaft on which a substantially disc-shaped element is fixed, on which the lever is mounted eccentrically rotatable. The lever may in particular be mounted rotatably on the plate holder. This makes it possible to implement the rotational movement of the substantially disc-shaped element in a sliding movement of the disc holder in a plane within the intake panel and thus to effect the parallel displacement of the slats in the use position or back to the non-use position. In addition, in an advantageous embodiment, at least one first pivoting lug, which is pivotally connected to the lamellar holder, can be pivotably arranged in the interior of the intake panel. Further, in the interior of the intake panel, a second pivoting lug may be pivotally mounted, which is pivotally connected to the lamella holder.
Vorzugsweise umfasst jede der Lamellen einen Grundkörper und ein im Wesentlichen plattenförmiges Abschlusselement, das am Grundkörper angebracht ist. Die Grundkörper der Lamellen können insbesondere unmittelbar am Lamellenhalter befestigt sein. Die Abschlusselemente, die sich vorzugsweise über die gesamte Breite des Ansaugpaneels erstrecken, können insbesondere aus Glas, Kunststoff oder Metall bestehen.Preferably, each of the lamellae comprises a base body and a substantially plate-shaped closure element, which is attached to the base body. The main body of the lamellae can in particular be fastened directly on the lamella holder. The End elements, which preferably extend over the entire width of the intake panel, may consist in particular of glass, plastic or metal.
Die Ansaugfläche des Ansaugpaneels kann in einer vorteilhaften Ausführungsform eine Anzahl stationärer (somit also nicht bewegbarer) Verkleidungselemente aufweisen. Die Verkleidungselemente können ebenfalls aus Glas, Kunststoff oder Metall bestehen und sich vorzugsweise über die gesamte Breite des Ansaugpaneels erstrecken. Es besteht in einer besonders bevorzugten Ausführungsform die Möglichkeit, dass in vertikaler Richtung der Ansaugfläche neben jedem der Verkleidungselemente zumindest eine der Lamellen angeordnet ist. Um das optische Erscheinungsbild der Dunstabzugsvorrichtung zu verbessern, ist es bevorzugt, dass die bewegbaren Lamellen in der Nichtgebrauchsstellung flächenbündig mit den Verkleidungselementen abschließen. Dadurch kann ein optisch stimmiges Erscheinungsbild des Ansaugpaneels in der Nichtgebrauchsstellung erhalten werden.In an advantageous embodiment, the suction surface of the suction panel can have a number of stationary (and therefore not movable) lining elements. The cladding elements can also be made of glass, plastic or metal and preferably extend over the entire width of the intake panel. In a particularly preferred embodiment, there is the possibility that at least one of the lamellae is arranged in the vertical direction of the suction surface next to each of the lining elements. In order to improve the visual appearance of the extractor device, it is preferred that the movable slats in the non-use position flush with the cladding elements. As a result, a visually harmonious appearance of the intake panel in the non-use position can be obtained.
In einer besonders vorteilhaften Ausführungsform kann vorgesehen sein, dass zumindest einer der Grundkörper der Lamellen mindestens ein Hakenelement aufweist, welches dazu geeignet ist, einen Randbereich eines benachbarten Verkleidungselements des Ansaugpaneels in der Gebrauchsstellung zu hintergreifen. Dadurch kann die Gebrauchsstellung der Lamellen zusätzlich stabilisiert werden.In a particularly advantageous embodiment it can be provided that at least one of the main body of the slats has at least one hook element, which is adapted to engage behind an edge region of an adjacent cladding element of the intake panel in the position of use. As a result, the position of use of the slats can be additionally stabilized.
In einer vorteilhaften Ausführungsform wird vorgeschlagen, dass die Dunstabzugsvorrichtung einen Faltenbalg umfasst, der sich zwischen dem Ansaugpaneel und dem Gehäuse der Absaugeinheit erstreckt und eine Strömungsverbindung zwischen dem Ansaugpaneel und dem Gehäuse bereitstellt. Mit Hilfe des Faltenbalgs, der zweckmäßig aus einem Material besteht, welches für die angesaugten Kochdämpfe undurchlässig ist, kann eine sehr flexible Strömungsverbindung zwischen dem Ansaugpaneel und der Absaugeinheit hergestellt werden.In an advantageous embodiment, it is proposed that the extractor device comprises a bellows which extends between the suction panel and the housing of the suction unit and provides a flow connection between the suction panel and the housing. With the help of the bellows, which expediently consists of a material which is impermeable to the extracted cooking vapors, a very flexible flow connection between the suction panel and the suction unit can be produced.
Um das optische Erscheinungsbild bei einer Montage der Dunstabzugsvorrichtung in einer Einbauöffnung einer Wand zu verbessern, sieht eine besonders vorteilhafte Ausführungsform vor, dass das Ansaugpaneel in der Nichtgebrauchsstellung flächenbündig mit der Wand abschließt.In order to improve the visual appearance when mounting the extractor device in an installation opening of a wall, a particularly advantageous embodiment provides that the intake panel in the non-use position is flush with the wall.
Um die während des Betriebs der Dunstabzugsvorrichtung von der Kochstelle angesaugten Dämpfe zu filtern, wird in einer besonders bevorzugten Ausführungsform vorgeschlagen, dass die Dunstabzugsvorrichtung mindestens ein Filterelement aufweist, geeignet, Fett und/oder Gerüche aus den angesaugten Kochdämpfen herauszufiltern. Vorzugsweise ist das mindestens eine Filterelement innerhalb des Ansaugpaneels untergebracht. An Stelle eines einzelnen Filterelements können in alternativen Ausführungsformen auch mehrere nebeneinander und/oder hintereinander angeordnete Filterelemente vorgesehen sein. Bei mehrlagig angeordneten Filterelementen kann zum Beispiel eines der Filterelemente zum Filtern von Fett und eines der Filterelemente zum Filtern von Gerüchen vorgesehen sein. Das Vorsehen eines Filterelements, das zum Filtern von Gerüchen geeignet ist, ist insbesondere dann vorteilhaft, wenn die Dunstabzugsvorrichtung für einen Umluftbetrieb eingerichtet ist.In order to filter the vapors drawn in during the operation of the extractor device from the cooking point, it is proposed in a particularly preferred embodiment that the extractor device has at least one filter element suitable for filtering out grease and / or odors from the extracted cooking vapors. Preferably, the at least one filter element is housed within the intake panel. Instead of a single filter element, it is also possible, in alternative embodiments, to provide a plurality of filter elements arranged side by side and / or one behind the other. In multi-layered filter elements, for example, one of the filter elements for filtering grease and one of the filter elements may be provided for filtering odors. The provision of a filter element that is suitable for filtering odors is particularly advantageous when the extractor device is set up for recirculation mode.

Die Filteraufnahme 33 ist über zwei beabstandet voneinander angeordnete Scharniere 34a, 34b schwenkbar am Gehäuserahmen 36 des Ansaugpaneels 3 angeordnet. Ferner sind zwei Verriegelungselemente 35a, 35b vorgesehen, die auf einer den beiden Scharnieren 34a, 34b gegenüberliegenden Seite angeordnet sind, um die Filteraufnahme 33 in der geschlossenen Stellung am Gehäuserahmen 36 zu verriegeln. In der Filteraufnahme 33 ist in dem hier dargestellten Ausführungsbeispiel ein Filterelement 12 untergebracht, um Fett und/oder Gerüche aus den von der Dunstabzugsvorrichtung 1 während des Betriebs angesaugten Kochdämpfen herauszufiltern. An Stelle eines einzelnen Filterelements 12 können in einer alternativen Ausführungsform auch mehrere nebeneinander und/oder hintereinander angeordnete Filterelemente 12 vorgesehen sein. Bei mehrlagig angeordneten Filterelementen 12 kann zum Beispiel eines der Filterelemente 12 zum Filtern von Fett und eines der Filterelemente 12 zum Filtern von Gerüchen vorgesehen sein. Damit das Filterelement 12 beziehungsweise jedes der Filterelemente 12, welches in der Filteraufnahme 33 des Ansaugpaneels 3 angeordnet ist, bei Bedarf ausgetauscht werden kann und/oder andere Wartungs- beziehungsweise Reinigungsarbeiten durchgeführt werden können, kann das Ansaugpaneel 3 nach dem Entriegeln der beiden Verriegelungselemente 35a, 35b durch Verschwenken des Gehäuserahmens 36 relativ zur Filteraufnahme 33 in eine Revisionsstellung überführt werden, welche in
Wie oben bereits erwähnt und in
In der Absaugposition kann das Sauggebläse 8 der Absaugeinheit 7 von einem Benutzer durch Betätigen eines Tasters, Schalters oder berührungssensitiven Elements aktiviert werden, so dass Kochdämpfe von der Kochstelle angesaugt werden können, die durch die Einströmbereiche in das Ansaugpaneel 3 einströmen, wo sie dann von dem mindestens einen Filterelement 12, welches als Fett- und/oder Geruchsfilter dient, gefiltert werden. Die von dem mindestens einen Filterelement 12 gefilterten Kochdämpfe können dann durch den Faltenbalg 9 in das Gehäuse 70 der Absaugeinheit 7 einströmen und das Sauggebläse 8 passieren. Anschließend werden die Kochdämpfe durch den Abluftstutzen 71 in die Abluftleitung, welche hier hinter der Wand 2 vorgesehen ist, geleitet und dadurch aus der Dunstabzugsvorrichtung 1 ausgetragen. Alternativ zur vorstehend erwähnten manuellen Aktivierung des Sauggebläses 8 besteht auch die Möglichkeit, dass das Sauggebläse 8 automatisch aktiviert wird, wenn das Ansaugpaneel 3 und die Lamellen 4a, 4b, 4c ihre Gebrauchsstellung erreichen. Das Sauggebläse 8 weist vorzugsweise mehrere Saugstufen mit unterschiedlichen Saugleistungen auf, die von einem Benutzer manuell eingestellt werden können. Es wird deutlich, dass das hier gezeigte Ausführungsbeispiel der Dunstabzugsvorrichtung 1 für einen Abluftbetrieb eingerichtet ist. In einer alternativen Ausführungsform kann die vorstehend beschriebene Dunstabzugsvorrichtung 1 mit entsprechend angepassten Strömungsführungen auch für einen Umluftbetrieb eingerichtet sein. Wenn die Dunstabzugsvorrichtung 1 für einen Umluftbetrieb eingerichtet ist, kann die gefilterte Luft wieder in den Raum, in dem die Dunstabzugsvorrichtung 1 installiert ist, einströmen.In the suction position, the

Um eine Verschiebebewegung der Lamellen 4a, 4b, 4c in die Absaugposition einzuleiten, ist innerhalb des Ansaugpaneels 3 ein Getriebemotor 83 untergebracht, der vorzugsweise synchron mit dem Motor 11 betreibbar ist, welcher die Schwenkbewegung des Ansaugpaneels 3 bewirkt. Alternativ ist auch ein asynchroner Betrieb des Motors 11 mit dem Getriebemotor 83 möglich. Der Getriebemotor 83 weist eine drehbare Welle 84 auf, an der ein im Wesentlichen scheibenförmiges Element 85 befestigt ist. Das scheibenförmige Element 85 ist über einen Hebel 86, der exzentrisch drehbar an dem scheibenförmigen Element 85 angebracht ist und sich zum Lamellenhalter 80 hin erstreckt und daran drehbeweglich angebracht ist, mit dem Lamellenhalter 80 gekoppelt. Bei der Überführung der Lamellen 4a, 4b, 4c aus der Nichtgebrauchsstellung in die Gebrauchsstellung (Absaugposition) wird das scheibenförmige Element 85 in dieser Darstellung im Uhrzeigersinn um 180° gedreht und dadurch von der in
Die mittlere Lamelle 4b sowie die untere, an den Hebel 86 angrenzende Lamelle 4c des Ansaugpaneels 3 weisen in diesem Ausführungsbeispiel jeweils ein Hakenelement 40 auf, welches am Lamellengrundkörper 41 der jeweiligen Lamelle 4b, 4c angebracht ist und dazu geeignet ist, einen Randbereich eines benachbarten Verkleidungselements 5a, 5b des Ansaugpaneels 3 in der Absaugposition zu hintergreifen. Die Verkleidungselemente 5a, 5b dienen somit gewissermaßen als Anschlag für die Hakenelemente 40 der Lamellen 4b, 4c und legen dadurch die Lamellen 4b, 4c in der Absaugposition am benachbarten Verkleidungselement 5a, 5b fest. In

Um ein Einquetschen der Finger des Benutzers während der Bewegung der Lamellen 4a, 4b, 4c zu verhindern und damit die Gefahr von Verletzungen zu verringern, können bei den hier vorgestellten Dunstabzugsvorrichtungen 1 entsprechende konstruktive Maßnahmen ergriffen werden. Der Getriebemotor 83 kann beispielsweise so ausgeführt sein, dass er sich leistungsbedingt abschaltet. Alternativ kann der Getriebemotor 83 zusätzlich eine Widerstandsschaltung umfassen, die bei einem mechanischen Widerstand ein Abschalten des Getriebemotors 83 und damit einen Stop der Ausfahr- beziehungsweise Einfahrbewegungen der Lamellen 4a, 4b, 4c bewirken kann.In order to prevent pinching of the user's fingers during the movement of the
Um Verletzungen bei den Schwenkbewegungen des Ansaugpaneels 3 zu vermeiden, können ebenfalls geeignete konstruktive Maßnahmen ergriffen werden. Das Ansaugpaneel 3 kann zum Beispiel zumindest einen Druckschalter oder Drucksensor umfassen, der bei einer Belastung des Ansaugpaneels 3 durch einen mechanischen Widerstand eine Sicherheitsabschaltung auslösen kann. Ferner können die Schwenkbewegungen des Ansaugpaneels 3 durch einen Tastschalter ausgelöst werden, der beim Loslassen bewirkt, dass die Schwenkbewegung des Ansaugpaneels 3 zum Stillstand kommt. Alternativ kann auch vorgesehen sein, dass das Loslassen des Tastschalters beim Einschwenken des Ansaugpaneels 3 bewirkt, dass sich die Richtung der Schwenkbewegung umkehrt und das Ansaugpaneel 3 somit wieder in seine Gebrauchsstellung schwenkt.In order to avoid injuries during the pivoting movements of the
Alternativ zu den vorgenannten Ausführungsbeispielen ist es denkbar, dass die Bewegung der Lamellen 4a, 4b, 4c mittels mechanischer Kopplungsglieder mit der Bewegung des Ansaupaneels gekoppelt ist. Auf diese Weise ist der Getriebemotor 83 nicht erforderlich.Alternatively to the aforementioned embodiments, it is conceivable that the movement of the
Bei einer weiteren alternativen Ausführungsform ist es auch denkbar, dass das Ansaugpaneel relativ zur Absaugeinheit nicht bewegbar, insbesondere nicht verschwenkbar, ausgebildet ist. Hier wären dann lediglich die Lamellen manuell oder motorisch bewegbar.In a further alternative embodiment, it is also conceivable that the suction panel is not movable, in particular not pivotable, relative to the suction unit. Here then only the slats would be manually or motorized movable.
