Description
Die vorliegende Erfindung betrifft eine Dunstabzugsvorrichtung mit Abdeckung fĆ¼r eine GehƤuseƶffnung des DunstabzugsgehƤuses einer Dunstabzugsvorrichtung.The present invention relates to a fume extraction device with cover for a housing opening of the extractor housing of a fume extraction device.
Herkƶmmliche Dunstabzugshauben verfĆ¼gen Ć¼ber FilterflƤchen zur Fettabscheidung des beim Kochen entstehenden Luft-Wasser-Fettgemisches, das auch als Wrasen bezeichnet wird. Ćblicherweise werden hierbei Metallgewebefilter oder Streckmetallfilter eingesetzt, die an der dem Kochfeld zugewandten Unterseite der Dunstabzugshaube befindlich sind.Conventional extractor hoods have filter surfaces for grease separation of the resulting air-water-fat mixture, which is also referred to as vapors. Usually this metal mesh filters or expanded metal filters are used, which are located on the cooktop facing the bottom of the hood.
FĆ¼r Dunstabzugsvorrichtungen, insbesondere Dunstabzugshauben, ist in den letzten Jahren vorgeschlagen worden, die Absaugƶffnung der Dunstabzugshaube, die auch als GehƤuseƶffnung des DunstabzugsgehƤuses bezeichnet werden kann, mit einer Prallplatte weitestgehend abzudecken. Diese Art der Absaugung wird auch als Randabsaugung bezeichnet. Hierbei bedeutet Randabsaugung, dass die eigentlichen FilterflƤchen, die in der GehƤuseƶffnung liegt oder in Strƶmungsrichtung hinter der GehƤuseƶffnung liegt, von einer Metall- oder Glasabdeckung kaschiert werden. Um diese Abdeckung, die auch als Prallplatte bezeichnet wird, verlƤuft ein umlaufender Spalt, in den Wrasen eintritt beziehungsweise eingesaugt wird. Der Vorteil dieser GerƤtegestaltung besteht darin, dass diese eine gute optische Gesamterscheinung hat und eventuelle Verschmutzungen der FilterflƤche nicht offensichtlich werden. Ein Nachteil besteht aber darin, dass auch in dem Zustand, in dem die Dunstabzugsvorrichtung nicht verwendet wird, der Randspalt offen ist und darĆ¼ber Verunreinigungen, wie Staub und dergleichen in die Dunstabzugsvorrichtung eintreten kƶnnen und sich an den Filterelementen ablagern kƶnnen. Zudem kƶnnen gegebenenfalls GerĆ¼che Ć¼ber den Randspalt austreten.For extractor devices, in particular extractor hoods, it has been proposed in recent years, the exhaust opening of the hood, which can also be referred to as the housing opening of the extractor hood to cover as far as possible with a baffle plate. This type of suction is also referred to as edge suction. In this case, edge suction means that the actual filter surfaces, which lie in the housing opening or lie downstream of the housing opening, are covered by a metal or glass cover. To this cover, which is also referred to as a baffle plate, runs a circumferential gap, enters the vapors or is sucked. The advantage of this device design is that it has a good visual appearance and any contamination of the filter surface are not obvious. A disadvantage, however, is that even in the state in which the extractor device is not used, the edge gap is open and impurities such as dust and the like can enter into the extractor device and can be deposited on the filter elements. In addition, if necessary, odors can escape via the edge gap.

Aufgabe der vorliegenden Erfindung ist es daher eine Dunstabzugsvorrichtung zu schaffen, die ein verbessertes optisches Erscheinungsbild bei einfachem Aufbau hat, die aber dennoch ein zuverlƤssiges Absaugen von DĆ¼nsten und Wrasen erlaubt und bei der der Bedarf an Bauraum minimiert ist.Object of the present invention is therefore to provide a fume extraction device, which has an improved visual appearance with a simple structure, but still allows a reliable suction of fumes and vapors and in which the need for space is minimized.
Der Erfindung liegt die Erkenntnis zugrunde, dass diese Aufgabe gelƶst werden kann, indem ein KraftĆ¼bertragungselement verwendet wird, das eine Beeinflussung der Abdeckung aus der Entfernung erlaubt.The invention is based on the finding that this object can be achieved by using a force transmission element which allows the cover to be influenced from a distance.
Die Aufgabe wird erfindungsgemĆ¤Ć gelƶst durch eine Dunstabzugsvorrichtung mit einem DunstabzugsgehƤuse, einer in dem DunstabzugsgehƤuse vorgesehenen GehƤuseƶffnung und mindestens einer Abdeckung fĆ¼r zumindest einen Teil der GehƤuseƶffnung. Die Dunstabzugsvorrichtung ist dadurch gekennzeichnet, dass die Abdeckung zu dem DunstabzugsgehƤuse beweglich gelagert ist und die Dunstabzugsvorrichtung eine BetƤtigungsvorrichtung umfasst, die mindestens einen Bowdenzug aufweist, der so angeordnet ist, dass zumindest ein Ende des Bowdenzuges mit der Seite der Abdeckung, die dem Inneren des DunstabzugsgehƤuses zugewandt ist, verbunden ist.The object is achieved by a fume extraction device with a fume hood, a housing provided in the extractor housing opening and at least one cover for at least a portion of the housing opening. The extractor device is characterized in that the cover is movably mounted to the extractor housing and the extractor device comprises an actuating device having at least one Bowden cable which is arranged so that at least one end of the Bowden cable with the side of the cover, the interior of the extractor housing facing is connected.
Als Dunstabzugsvorrichtung wird eine Vorrichtung bezeichnet, mittels derer DĆ¼nste und Wrasen, die beispielsweise beim Kochen entstehen, eingesaugt und gereinigt, insbesondere gefiltert werden kƶnnen. Die Dunstabzugsvorrichtung stellt vorzugsweise einen DeckenlĆ¼fter dar. Alternativ kann die Dunstabzugsvorrichtung einen TischlĆ¼fter darstellen. Die Dunstabzugsvorrichtung weist ein DunstabzugsgehƤuse auf. In diesem DunstabzugsgehƤuse ist vorzugsweise zumindest ein Filterelement angeordnet. Das Filterelement oder die Filterelemente stellen vorzugsweise flƤchige Filterelemente dar, die auch als Filterkassetten bezeichnet werden kƶnnen. Zudem ist vorzugsweise in dem DunstabzugsgehƤuse der LĆ¼fter der Dunstabzugsvorrichtung angeordnet. Das DunstabzugsgehƤuse weist eine GehƤuseƶffnung auf, die auch als Ansaugƶffnung bezeichnet werden kann. Ćber diese GehƤuseƶffnung kann zumindest bereichsweise Luft in das DunstabzugsgehƤuse eintreten.As a vapor extraction device, a device is referred to, by means of which fumes and vapor, which arise for example during cooking, sucked in and cleaned, in particular can be filtered. The extractor device preferably constitutes a ceiling ventilator. Alternatively, the extractor device may be a table ventilator. The extractor device has a fume hood housing. In this extractor housing, at least one filter element is preferably arranged. The filter element or the filter elements preferably represent flat filter elements, which can also be referred to as filter cassettes. In addition, the fan of the extractor device is preferably arranged in the extractor housing. The extractor housing has a housing opening, which can also be referred to as a suction opening. At least partially, air can enter the extractor housing via this housing opening.
Das DunstabzugsgehƤuse kann an oder in die Raumdecke des Raumes, in dem die Dunstabzugsvorrichtung betrieben wird, an- oder eingebracht werden. Das DunstabzugsgehƤuse kann auch mittelbar an der Raumdecke befestigt sein, beispielsweise mittels Seilen oder DrƤhten, die gegebenenfalls auch lƤngenverstellbar sein kƶnnen. Vorzugsweise wird das DunstabzugsgehƤuse in die Raumdecke eingebracht. Bei einem TischlĆ¼fter, der auch als MuldenlĆ¼fter bezeichnet wird, ist das DunstabzugsgehƤuse in einer Arbeitsplatte neben einem Kochfeld oder in dem Kochfeld integriert.The extractor housing can be on or in the ceiling of the room in which the extractor device is operated, or introduced. The extractor housing may also be attached indirectly to the ceiling, for example by means of cables or wires, which may optionally be adjustable in length. Preferably, the extractor housing is introduced into the ceiling. In a desk ventilator, which is also referred to as a tray ventilator, the extractor housing is integrated in a worktop next to a hob or in the hob.
Die erfindungsgemƤĆe Dunstabzugsvorrichtung weist zudem mindestens eine Abdeckung fĆ¼r zumindest einen Teil der GehƤuseƶffnung auf. Als Abdeckung wird hierbei ein Bauteil, das vorzugsweise eine Platte oder Klappe darstellt, bezeichnet, das so angeordnet ist, dass dieses in Strƶmungsrichtung vor dem Filterelement liegt und die FilterflƤche in senkrechter Projektion auf die FilterflƤche des Filterelementes zumindest teilweise abdeckt. Die Abdeckung liegt zumindest zeitweise in der GehƤuseƶffnung oder liegt im Bereich der GehƤuseƶffnung an. Die Abdeckung verschlieĆt die GehƤuseƶffnung entweder alleine oder zusammen mit weiteren Teilen, wie beispielsweis einer Mittelplatte.The extractor device according to the invention also has at least one cover for at least part of the housing opening. As a cover here is a component, which preferably represents a plate or flap, which is arranged so that it lies in the flow direction in front of the filter element and at least partially covers the filter surface in the vertical projection on the filter surface of the filter element. The cover is at least temporarily in the housing opening or is located in the region of the housing opening. The cover closes the housing opening either alone or together with other parts, such as a center plate.
Die Abdeckung ist erfindungsgemĆ¤Ć zu dem DunstabzugsgehƤuse beweglich gelagert. Insbesondere kann die Abdeckung relativ zu dem DunstabzugsgehƤuse und insbesondere der GehƤuseƶffnung eine translatorische Bewegung und/oder eine Schwenkbewegung ausfĆ¼hren. Vorzugsweise kann die Abdeckung in zumindest zwei unterschiedliche Positionen gebracht werden, wobei eine als Ruheposition und eine als Betriebsposition bezeichnet wird. In der Ruheposition befindet sich die Abdeckung in einem Zustand, in dem dieser an dem DunstabzugsgehƤuse anliegt oder in dieses in der GehƤuseƶffnung aufgenommen ist. In der Betriebsposition befindet sich die Abdeckung in einem Zustand, in dem zumindest ein Teil der Abdeckung von dem DunstabzugsgehƤuse entfernt liegt, das heiĆt nicht in dem DunstabzugsgehƤuse und nicht in der GehƤuseƶffnung liegt und dadurch Luft in das DunstabzugsgehƤuse eintreten kann. Befindet sich die Abdeckung in der Betriebsposition, kann die Dunstabzugsvorrichtung betrieben werden, das heiĆt verunreinigte Luft eingesaugt und gereinigt, insbesondere gefiltert werden.The cover according to the invention is movably mounted to the extractor housing. In particular, the cover can perform a translatory movement and / or a pivoting movement relative to the extractor housing and in particular the housing opening. Preferably, the cover can be brought into at least two different positions, one being referred to as a rest position and one as an operating position. In the rest position, the cover is in a state in which this rests on the extractor housing or is accommodated in this in the housing opening. In the operating position, the cover is in a state in which at least a portion of the cover is removed from the extractor housing, that is not in the extractor housing and not in the housing opening and thereby air can enter the extractor housing. The cover is in the operating position, the extractor device can be operated, that is sucked in polluted air and cleaned, in particular filtered.
Die Dunstabzugsvorrichtung umfasst eine BetƤtigungsvorrichtung. Mittels der BetƤtigungsvorrichtung kann die Abdeckung bewegt werden. Insbesondere kann die Abdeckung zumindest von einer Position in eine weitere Position gebracht werden. Besonders bevorzugt wird die Abdeckung durch die BetƤtigungsvorrichtung von einer Ruheposition in eine Betriebsposition oder von der Betriebsposition in die Ruheposition gebracht. Der Ćbergang zwischen diesen beiden Positionen kann stufenlos erfolgen. Die Abdeckung kann dabei in jeder beliebigen Zwischenposition angehalten werden.The extractor device comprises an actuating device. By means of the actuator, the cover can be moved. In particular, the cover can be brought at least from one position to another position. Particularly preferably, the cover is brought by the actuator from a rest position to an operating position or from the operating position to the rest position. The transition between these two positions can be stepless. The cover can be stopped in any intermediate position.
Die BetƤtigungsvorrichtung umfasst zumindest einen Bowdenzug. Als Bowdenzug wird ein KraftĆ¼bertragungselement bezeichnet, das aus mindestens einem Innenseil, das auch als Innenzug oder Zugseil bezeichnet werden kann und einer HĆ¼lle, die auch als ZughĆ¼lle bezeichnet werden kann, besteht. Das Innenseil kann aus Draht, insbesondere Stahldraht bestehen. Das Innenseil kann erfindungsgemĆ¤Ć vorzugsweise ZugkrƤfte Ć¼bertragen. GemĆ¤Ć einer AusfĆ¼hrungsform ist das Innenseil aber so ausgelegt, dass dieses zusƤtzlich zu den ZugkrƤften auch DruckkrƤfte Ć¼bertragen kann. Bei dieser AusfĆ¼hrungsform kann das Innenseil als eine flexible Welle ausgefĆ¼hrt sein, die in der LƤngsrichtung druckfest ist. Die HĆ¼lle des Bowdenzugs ist vorzugsweise in der LƤngsrichtung des Innenseils, insbesondere der Zugrichtung des Innenseils starr, das heiĆt druckfest. Somit wirkt die HĆ¼lle als FĆ¼hrung des Innenseils. Zudem wirkt die HĆ¼lle insbesondere beim Aufbrungen von ZugkrƤften mittels des Innenseils als Gegenlager fĆ¼r die ZugkrƤfte, die auf das oder die Innenseile ausgeĆ¼bt werden sollen.The actuating device comprises at least one Bowden cable. As a Bowden cable, a force transmission element is referred to, which consists of at least one inner cable, which may also be referred to as inner cable or pull rope and a shell, which may also be referred to as a cable housing. The inner cable can be made of wire, especially steel wire. The inner cable according to the invention can preferably transmit tensile forces. According to one embodiment, however, the inner cable is designed such that it can transmit compressive forces in addition to the tensile forces. In this embodiment, the inner cable can be designed as a flexible shaft which is pressure-resistant in the longitudinal direction. The sheath of the Bowden cable is preferably rigid in the longitudinal direction of the inner cable, in particular the pulling direction of the inner cable, that is to say pressure-resistant. Thus, the shell acts as a guide of the inner cable. In addition, the shell acts in particular when Aufbrungen of tensile forces by means of the inner cable as an abutment for the tensile forces to be exerted on the one or more inner cables.
Der Bowdenzug ist so angeordnet ist, dass zumindest ein Ende des Bowdenzuges mit der Seite der Abdeckung, die dem Inneren des DunstabzugsgehƤuses zugewandt ist, verbunden ist. Die Verbindung mit dieser Seite der Abdeckung kann mittelbar oder unmittelbar erfolgen. Bei einer mittelbaren Verbindung wird beispielsweise ein Verbindungselement, das ein starres Stabelement darstellen kann, an der Abdeckung befestigt und ein Ende des Bowdenzugs wird mit dem Ende des Verbindungselementes, das der Abdeckung abgewandt ist, verbunden. Die Seite an der der Bowdenzug mit der Abdeckung verbunden ist, ist die Seite, die dem Inneren des DunstabzugsgehƤuses und damit vorzugsweise dem oder den Filterelementen zugewandt ist. Diese Seite ist bei einer Dunstabzugsvorrichtung, die einen DeckenlĆ¼fter mit horizontal liegender GehƤuseƶffnung darstellt, die Oberseite der Abdeckung. Bei einer Dunstabzugsvorrichtung, die einen TischlĆ¼fter mit horizontal liegender GehƤuseƶffnung darstellt, ist diese Seite die Unterseite der Abdeckung. Indem der Bowdenzug an dieser Seite mit der Abdeckung verbunden ist, kann dieser auf die Abdeckung eine nach oben oder unten gerichtete Zugkraft aufbringen und/oder bei einem starren Innenseil eine nach oben oder unten gerichtete Druckkraft aufbringen. Der Bowdenzug kann somit die Abdeckung aus einer ausgefahrenen oder ausgeklappten Position, das heiĆt der Betriebsposition, in die Ruheposition gebracht, insbesondere gezogen oder gedrĆ¼ckt werden.The Bowden cable is arranged so that at least one end of the Bowden cable is connected to the side of the cover which faces the interior of the extractor housing. The connection with this side of the cover can be indirect or immediate. In an indirect connection, for example, a connecting element, which may be a rigid rod member, attached to the cover and one end of the Bowden cable is connected to the end of the connecting element, which faces away from the cover. The side on which the Bowden cable is connected to the cover is the side which faces the interior of the extractor housing and thus preferably the filter element (s). This page is on a fume extractor, which is a ceiling fan with horizontal housing opening, the top of the cover. In a fume extractor, which is a table fan with horizontal housing opening, this side is the bottom the cover. By the Bowden cable is connected at this side with the cover, this can apply to the cover an upward or downward tensile force and / or apply a directed upward or downward pressure force in a rigid inner cable. The Bowden cable can thus bring the cover from an extended or unfolded position, that is the operating position, in the rest position, in particular pulled or pressed.
Die Erfindung wird im Folgenden fĆ¼r das bessere VerstƤndnis anhand einer Dunstabzugsvorrichtung mit einer BetƤtigungsvorrichtung beschrieben, die einen Bowdenzug mit einem Innenseil aufweist. Vorzugsweise werden aber mehrere Befestigungsvorrichtungen oder eine Befestigungsvorrichtung mit mehreren BowdenzĆ¼gen oder mit einem Bowdenzug mit mehreren Innenseilen verwendet.The invention will be described below for better understanding with reference to an extractor device with an actuator which has a Bowden cable with an inner cable. Preferably, however, a plurality of fastening devices or a fastening device with a plurality of Bowden cables or with a Bowden cable with several inner cables are used.
Der Vorteil der Verwendung zumindest eines Bowdenzuges in der BetƤtigungsvorrichtung der Dunstabzugsvorrichtung besteht darin, dass der Ort der Kraftaufbringung auf den Bowdenzug zu der Abdeckung beabstandet liegen kann. Somit ist der Bauraum, der unmittelbar Ć¼ber oder unter der Abdeckung erforderlich ist minimiert. Zudem kann beispielsweise ein Antriebsmotor fĆ¼r den Bowdenzug an einem Ort in der Dunstabzugsvorrichtung angeordnet werden, der auĆerhalb des direkten Strƶmungsweges der zu reinigenden Luft liegt. Hierdurch kann das zuverlƤssige Absaugen von Luft und der zuverlƤssige Betrieb der Dunstabzugsvorrichtung gewƤhrleistet werden und der Antriebsmotor vor Verunreinigungen geschĆ¼tzt werden.The advantage of using at least one Bowden cable in the actuating device of the extractor device is that the location of the force application can be spaced on the Bowden cable to the cover. Thus, the space required immediately above or below the cover is minimized. In addition, for example, a drive motor for the Bowden cable can be arranged at a location in the extractor device, which is outside the direct flow path of the air to be cleaned. In this way, the reliable suction of air and the reliable operation of the extractor device can be ensured and the drive motor can be protected from contamination.
GemĆ¤Ć einer bevorzugten AusfĆ¼hrungsform umfasst der Bowdenzug mindestens ein Innenseil und eine HĆ¼lle und das Innenseil ist mit der Abdeckung verbunden ist. Sind mehrere Innenseile vorgesehen, so kƶnnen diese mit einer Abdeckung oder mit unterschiedlichen Abdeckungen verbunden werden. Insbesondere kƶnnen mehrere Innenseile eines Bowdenzuges mit einer Abdeckung an unterschiedlichen Stellen verbunden sein. Hierdurch kann die Kraftaufbringung auf die Abdeckung gleichmƤĆig erfolgen. Sind mehrere Abdeckungen vorgesehen, wird vorzugsweise fĆ¼r jede Abdeckung mindestens ein Bowdenzug verwendet. Das Innenseil weist vorzugsweise eine grƶĆere LƤnge als die HĆ¼lle auf. Die Verbindung des Innenseils mit der Abdeckung kann mittelbar oder unmittelbar erfolgen. Insbesondere kann das Innenseil beispielsweise an einem Verbindungselement, das auf der Oberseite der Abdeckung oder bei einem TischlĆ¼fter an der Unterseite der Abdeckung vorgesehen ist, befestigt werden. Das Verbindungselement kann ein starres Element, beispielsweise eine Stange darstellen.According to a preferred embodiment, the Bowden cable comprises at least one inner cable and a sheath and the inner cable is connected to the cover. If several inner cables are provided, they can be connected to a cover or with different covers. In particular, several inner cables of a Bowden cable can be connected to a cover at different locations. This allows the force applied to the cover evenly. If several covers are provided, at least one Bowden cable is preferably used for each cover. The inner cable preferably has a greater length than the sheath. The connection of the inner cable with the cover can be made directly or indirectly. In particular, the inner cable, for example, on a connecting element, which on the top of the cover or a table fan on the underside of the cover is provided, be attached. The connecting element may be a rigid element, for example a rod.
GemĆ¤Ć einer bevorzugten AusfĆ¼hrungsform ist an der Abdeckung zumindest ein Federelement angeordnet, das auf die Abdeckung eine Druckkraft ausĆ¼ben kann. Das Federelement ist daher vorzugsweise eine Druckfeder, die beispielsweise eine Schraubenfeder oder eine Schenkelfeder sein kann. Das Federelement ist so angeordnet, dass dieses eine Druckkraft auf die Abdeckung ausĆ¼ben kann. Diese AusfĆ¼hrungsform mit einem Federelement ist besonders bevorzugt bei einem Bowdenzug, bei dem das Innenseil eine geringe Festigkeit aufweist und insbesondere keine DruckkrƤfte Ć¼bertragen kann. Insbesondere wirkt die Druckkraft des Federelementes dabei in einer Richtung, die der Zugkraft, die durch den Bowdenzug auf die Abdeckung aufgebracht werden kann, entgegensteht. Das Federelement kann auf der Seite der Abdeckung einwirken, an der der Bowdenzug mit der Abdeckung verbunden ist. Alternativ ist es aber auch mƶglich, dass das Federelement beispielsweise in einem Gelenk vorgesehen ist, das an einer Kante der Abdeckung liegt und Ć¼ber das die Abdeckung gegenĆ¼ber der GehƤuseƶffnung verschwenkt werden kann. Durch das Federelement wird die Abdeckung in eine Betriebsposition gebracht, die auch als aktive Position bezeichnet werden kann. In der Ruheposition ist das Federelement daher vorgespannt und in der Betriebsposition vorzugsweise entspannt. Ein Vorteil der Verwendung eines Federelementes, das die Abdeckung in eine Betriebsposition bewegt, besteht darin, dass die Kraft, die zur Bewegung der Abdeckung aus der Betriebsposition in die Ruheposition notwendig ist, gering ist. Somit sind zum einen die Anforderungen an den Bowdenzug und einen vorzugsweise vorgesehenen Antriebsmotor verringert. Zum anderen ist die Zugkraft, die Ć¼ber den Bowdenzug aufgebracht werden muss, gering, so dass ein Einklemmschutz fĆ¼r den Benutzer gegeben ist, der lediglich diese geringere Zugkraft beim Einklemmen spĆ¼ren wĆ¼rde.According to a preferred embodiment, at least one spring element is arranged on the cover, which can exert a compressive force on the cover. The spring element is therefore preferably a compression spring, which may be, for example, a coil spring or a leg spring. The spring element is arranged so that it can exert a compressive force on the cover. This embodiment with a spring element is particularly preferred in a Bowden cable, in which the inner cable has a low strength and in particular can not transmit compressive forces. In particular, the pressure force of the spring element acts in a direction opposite to the tensile force that can be applied to the cover by the Bowden cable. The spring element can act on the side of the cover on which the Bowden cable is connected to the cover. Alternatively, it is also possible that the spring element is provided for example in a joint which is located on an edge of the cover and over which the cover can be pivoted relative to the housing opening. By the spring element, the cover is brought into an operating position, which can also be referred to as an active position. In the rest position, the spring element is therefore biased and preferably relaxed in the operating position. An advantage of using a spring element that moves the cover to an operative position is that the force necessary to move the cover from the operative position to the rest position is small. Thus, on the one hand, the requirements for the Bowden cable and a drive motor preferably provided are reduced. On the other hand, the tensile force that must be applied via the Bowden cable, low, so that a pinch protection for the user is given, which would feel only this lower traction when pinched.
GemĆ¤Ć einer bevorzugten AusfĆ¼hrungsform weist die BetƤtigungsvorrichtung eine Aufwickeleinheit auf, in der zumindest ein Teil zumindest eines Innenseils des Bowdenzuges aufgewickelt werden kann. Vorzugweise ist die Aufwickeleinheit an dem Ende des Bowdenzuges vorgesehen, das der Abdeckung abgewandt ist. Das Innenseil ragt zumindest an diesem Ende Ć¼ber die HĆ¼lle hinaus und kann somit auf einer Rolle aufgewickelt werden. Indem eine Aufwickeleinheit verwendet wird, ist der Betrag um den die Abdeckung durch die mittels des Bowdenzuges aufgebrachte Zugkraft oder Druckkraft bewegt werden kann, bei geringem Bauraumbedarf vergrƶĆert.According to a preferred embodiment, the actuating device has a take-up unit, in which at least a part of at least one inner cable of the Bowden cable can be wound up. Preferably, the take-up unit is provided at the end of the Bowden cable, which faces away from the cover. The inner cable protrudes at least at this end beyond the shell and can thus be wound up on a roll. By using a take-up unit, the amount is around the cover can be moved by the applied by means of the Bowden cable tensile force or compressive force, increased with little space requirement.
GemĆ¤Ć einer bevorzugten AusfĆ¼hrungsform sind in der Aufwickeleinheit zumindest eine Rolle und zumindest ein Antriebsmotor zum Antreiben der Rolle vorgesehen. Das Innenseil ist an einem Ende an der Rolle befestigt. Durch Antreiben der Rolle mittels des Antriebsmotors wird dadurch ein Aufwickeln des Innenseils bewirkt. Die Rolle ist hierzu vorzugsweise auf der Motorwelle des Antriebsmotors montiert. Die Rolle kann eine rotationssymmetrische, eine nicht-rotationssymmetrische, eine exzentrische und/oder zentrische Rolle sein.According to a preferred embodiment, at least one roller and at least one drive motor for driving the roller are provided in the take-up unit. The inner cable is attached to the roller at one end. By driving the roller by means of the drive motor thereby winding the inner cable is effected. For this purpose, the roller is preferably mounted on the motor shaft of the drive motor. The role may be a rotationally symmetric, a non-rotationally symmetric, an eccentric and / or centric role.
GemĆ¤Ć einer AusfĆ¼hrungsform ist die Rolle auf der Motorwelle des Antriebsmotors befestigt und zwischen der Rolle und der Motorwelle ist eine Rutschkupplung angeordnet. Durch das Vorsehen einer Rutschkupplung kann ein weiterer Einklemmschutz fĆ¼r den Benutzer beim Bewegen der Abdeckung aus der Betriebsposition in die Ruheposition geschaffen werden.According to one embodiment, the roller is mounted on the motor shaft of the drive motor and between the roller and the motor shaft, a slip clutch is arranged. By providing a slip clutch, a further anti-pinch protection for the user when moving the cover from the operating position to the rest position can be created.
GemĆ¤Ć einer AusfĆ¼hrungsform ist in mindestens einem Innenseil des Bowdenzuges mindestens eine Zugfeder integriert. Diese AusfĆ¼hrungsform ist insbesondere bei einem Bowdenzug, bei dem Zugkraft auf die Abdeckung aufgebracht werden soll, vorteilhaft. Durch diese Zugfeder kann ein weiterer Einklemmschutz geschaffen werden. Die Zugfeder ist vorzugsweise in dem Bereich des Innenseils vorgesehen, in dem dieses Ć¼ber die HĆ¼lle hinausragt. Dieser Bereich kann zwischen der Abdeckung und dem der Abdeckung zugewandten Ende der HĆ¼lle oder im Bereich des anderen Endes des Bowdenzuges liegen, insbesondere zwischen einer Aufwickeleinheit und dem dieser Einheit zugewandten Ende der HĆ¼lle.According to one embodiment, at least one tension spring is integrated in at least one inner cable of the Bowden cable. This embodiment is particularly advantageous in a Bowden cable in which tensile force is to be applied to the cover. By this spring another anti-trap can be created. The tension spring is preferably provided in the region of the inner cable in which this protrudes beyond the sheath. This area can be between the cover and the cover facing the end of the shell or in the region of the other end of the Bowden cable, in particular between a take-up unit and the unit facing this end of the shell.
ErfindungsgemĆ¤Ć ist es mƶglich, dass die BetƤtigungsvorrichtung ausschlieĆlich dazu dient, die mindestens eine Abdeckung aus einer Betriebsposition in eine Ruheposition bei einem DeckenlĆ¼fter oder alternativ aus einer Ruheposition in eine Betriebsposition bei einem TischlĆ¼fter zu bringen. Bei diesen AusfĆ¼hrungsformen kann die entgegengesetzte Bewegung von der Ruheposition in die Betriebsposition beziehungsweise alternativ aus der Betriebsposition in die Ruheposition beispielsweise durch die Schwerkraft erfolgen.According to the invention, it is possible that the actuating device serves exclusively to bring the at least one cover from an operating position to a rest position in a ceiling fan or alternatively from a rest position to an operating position in a desk ventilator. In these embodiments, the opposite movement from the rest position to the operating position or alternatively from the operating position to the rest position, for example, by gravity.
GemĆ¤Ć einer bevorzugten AusfĆ¼hrungsform kann die Abdeckung Ć¼ber die BetƤtigungsvorrichtung aber in eine Ruheposition und in eine Betriebsposition gebracht werden. GemĆ¤Ć einer AusfĆ¼hrungsform wird diese Bewegung der Abdeckung in zwei entgegengesetzte Richtungen durch einen Bowdenzug realisiert, dessen Innenseil in LƤngsrichtung starr ausgebildet ist und somit DruckkrƤfte sowie ZugkrƤfte Ć¼bertragen kann. Alternativ umfasst die BetƤtigungsvorrichtung vorzugsweise auĆer dem mindestens einen Bowdenzug zumindest ein Element, das eine Kraft auf die Abdeckung aufbringt, die der Zugkraft entgegengesetzt ist, die durch den Bowdenzug aufgebracht wird. Insbesondere umfasst die BetƤtigungsvorrichtung daher vorzugsweise ein Federelement, das eine Druckkraft auf die Abdeckung aufbringt.According to a preferred embodiment, however, the cover can be brought into a rest position and into an operating position via the actuating device. According to one embodiment, this movement of the cover is realized in two opposite directions by a Bowden cable whose inner cable is designed to be rigid in the longitudinal direction and thus can transmit compressive forces and tensile forces. Alternatively, the actuating device preferably comprises, in addition to the at least one Bowden cable, at least one element which applies a force to the cover which is opposite to the tensile force applied by the Bowden cable. In particular, therefore, the actuating device preferably comprises a spring element which applies a compressive force to the cover.
Die Abdeckung der Dunstabzugsvorrichtung kann eine Prallplatte oder eine Klappe darstellen.The cover of the extractor device may represent a baffle plate or a flap.
Als Prallplatte wird eine Platte bezeichnet, die in der Betriebsposition mit dem DunstabzugsgehƤuse einen umlaufenden Spalt bildet, Ć¼ber den Luft in das DunstabzugsgehƤuse eintreten kann. Die Prallplatte deckt dabei zumindest einen Teil der GehƤuseƶffnung des DunstabzugsgehƤuses und insbesondere des oder der in dem DunstabzugsgehƤuse angeordneten Filterelemente in Strƶmungsrichtung ab. Insbesondere deckt die Prallplatte zumindest einen Teil der FilterflƤche, das heiĆt der Anstrƶmseite des oder der Filterelemente ab. In der Ruheposition verschlieĆt die Prallplatte vorzugsweise die gesamte GehƤuseƶffnung des DunstabzugsgehƤuses.As a baffle plate is referred to a plate which forms a circumferential gap in the operating position with the extractor housing, can enter through the air into the extractor housing. The baffle plate covers at least part of the housing opening of the extractor housing and in particular of the one or more arranged in the extractor housing filter elements in the flow direction. In particular, the baffle plate covers at least part of the filter surface, that is to say the upstream side of the filter element (s). In the rest position, the baffle preferably closes the entire housing opening of the extractor housing.
In der AusfĆ¼hrungsform, bei der die Abdeckung eine Prallplatte darstellt, wird die Abdeckung translatorisch zu dem DunstabzugsgehƤuse bewegt, das heiĆt aus diesem ausgefahren oder eingefahren. Hierdurch wird gewƤhrleistet, dass der Randspalt Ć¼ber den Umfang der Prallplatte gleichmƤĆig ist und dadurch ein gleichmƤĆiges Absaugen von Luft gewƤhrleistet werden kann. Die translatorische Bewegung kann bei der erfindungsgemƤĆen Dunstabzugsvorrichtung durch einen oder mehrere BowdenzĆ¼ge realisiert sein, die je nach AusfĆ¼hrungsform an der Oberseite der Prallplatte bei einem DeckenlĆ¼fter oder der Unterseite der Prallplatte bei einem TischlĆ¼fter angreifen.In the embodiment in which the cover is a baffle plate, the cover is moved in translation to the extractor housing, that is, extended from this or retracted. This ensures that the edge gap is uniform over the circumference of the baffle plate and thus a uniform suction of air can be ensured. The translational movement can be realized in the extractor device according to the invention by one or more Bowden cables, which attack depending on the embodiment on the upper side of the baffle plate in a ceiling fan or the bottom of the baffle plate at a table fan.
GemĆ¤Ć einer weiteren AusfĆ¼hrungsform stellt die Abdeckung eine Klappe dar. Die Klappe ist vorzugsweise Ć¼ber ein Gelenk verschwenkbar an dem DunstabzugsgehƤuse gelagert ist. Durch die Verwendung einer BetƤtigungsvorrichtung, die mindestens einen Bowdenzug umfasst, kann bei dieser AusfĆ¼hrungsform die Klappe durch den Bowdenzug aus einer Betriebsposition in eine Ruheposition und/oder aus einer Ruheposition in eine Betriebsposition gebracht werden. Als Betriebsposition der Klappe wird die Position bezeichnet, in der diese gegenĆ¼ber dem DunstabzugsgehƤuse bei einem DecklĆ¼fter nach unten oder bei einem TischlĆ¼fter nach oben verschwenkt ist. Als Ruheposition wird die Position bezeichnet, in der die Klappe in der GehƤuseƶffnung der DunstabzugsgehƤuse liegt oder an dieser anliegt.According to a further embodiment, the cover is a flap. The flap is preferably mounted pivotably on the extractor housing via a joint is. By using an actuating device comprising at least one Bowden cable, in this embodiment, the flap can be brought by the Bowden cable from an operating position to a rest position and / or from a rest position to an operating position. The operating position of the flap is the position in which it is pivoted upwards relative to the extractor housing in the case of a cover ventilator or in the case of a table ventilator. As a rest position, the position is referred to, in which the flap lies in the housing opening of the extractor housing or rests against this.
GemĆ¤Ć einer AusfĆ¼hrungsform ist die Abdeckung eine Klappe, die Ć¼ber ein Gelenk schwenkbar mit dem DunstabzugsgehƤuse verbunden ist und in dem Gelenk ist ein Federelement integriert. Das Federelement stellt hierbei ein Druckfederelement, insbesondere eine Schenkelfeder dar. Durch diese AusfĆ¼hrungsform kann die Abdeckung durch das Gelenk und das darin vorgesehen Federelement aus der Ruheposition in die Betriebsposition gebracht werden, in der die Abdeckung gegenĆ¼ber der GehƤuseƶffnung bei einem DeckenlĆ¼fter nach unten beziehungsweise bei einem TischlĆ¼fter nach oben verschwenkt ist.According to one embodiment, the cover is a flap, which is connected via a hinge pivotally connected to the extractor housing and in the joint, a spring element is integrated. By this embodiment, the cover can be brought by the hinge and the spring element provided therein from the rest position to the operating position in which the cover relative to the housing opening in a ceiling fan down or at a Table fan is pivoted upwards.
GemĆ¤Ć einer AusfĆ¼hrungsform ist die mindestens eine Klappe an einer Mittelplatte des DunstabzugsgehƤuses angeordnet, die fest mit dem DunstabzugsgehƤuse verbunden ist.According to one embodiment, the at least one flap is arranged on a center plate of the extractor housing, which is firmly connected to the extractor housing.
Bei dieser AusfĆ¼hrungsform kann eine oder kƶnnen mehrere Klappen an der Mittelplatte angeordnet sein. Beispielsweise kann an zwei gegenĆ¼berliegenden Kanten der Mittelplatte jeweils eine Klappe anliegen. In der Ruheposition der Klappen liegen die Klappen mit der Mittelplatte des DunstabzugsgehƤuses in einer Ebene und verschlieĆen somit gemeinsam die GehƤuseƶffnung des DunstabzugsgehƤuses. In der Mittelplatte kann beispielsweise eine Beleuchtungsvorrichtung der Dunstabzugsvorrichtung angeordnet sein.In this embodiment, one or more flaps may be disposed on the center plate. For example, in each case a flap can rest on two opposite edges of the center plate. In the rest position of the flaps, the flaps lie with the center plate of the extractor housing in a plane and thus close together the housing opening of the extractor housing. In the center plate, for example, a lighting device of the extractor device can be arranged.

Die Prallplatte 12 ist in der Betriebsposition in Strƶmungsrichtung vor der GehƤuseƶffnung 100 angeordnet. In der dargestellten AusfĆ¼hrungsform liegt die Prallplatte 12 daher unter der GehƤuseƶffnung 100. Die Prallplatte 12 weist eine GrƶĆe auf, die der GrƶĆe der GehƤuseƶffnung 100 zumindest entspricht. Zwischen der Unterseite des DunstabzugsgehƤuses 10 und der Oberseite der Prallplatte 12 ist ein Randspalt 13 gebildet, Ć¼ber den Luft in das DunstabzugsgehƤuse 10 eintreten kann. Die Abdeckung 17, die als Prallplatte 12 ausgebildet ist, ist an dem DunstabzugsgehƤuse 10 beweglich befestigt. Die Bewegung der Prallplatte 12 erfolgt mittels einer BetƤtigungsvorrichtung 2, deren Prinzip in der

Soll die Prallplatte 12 aus der Ruheposition in die Betriebsposition gebracht werden, so kann das Federelement 22 durch einen Aktuator (nicht gezeigt) aktiviert werden. Das Federelement 22, das eine Druckfeder darstellt, drĆ¼ckt dabei die Prallplatte 12 nach unten und stĆ¼tzt sich gegen das Gegenlager 23. In der Betriebsposition kann das Federelement 22 weiterhin an dem Gegenlager 23 anliegen oder zu diesem nach unten versetzt liegen.If the baffle plate 12 is brought from the rest position to the operating position, the
Soll die Prallplatte 12 eingefahren werden, beispielsweise wenn die Dunstabzugsvorrichtung 1 ausgeschaltet wird, so wird der Antriebsmotor 200 angesteuert. Dieser wickelt einen Teil des Innenseils 210 auf die Rolle 201 auf. Hierdurch wird eine Zugkraft auf die Prallplatte 12 ausgeĆ¼bt und diese gegen die Federkraft des Federelementes 22 nach oben gezogen.If the baffle plate 12 are retracted, for example, when the extractor device 1 is turned off, the

In einer weiteren, nicht gezeigten AusfĆ¼hrungsform ist in der zweiten gezeigten AusfĆ¼hrungsform nach
Die Erfindung wurde im Wesentlichen anhand von AusfĆ¼hrungsformen beschrieben, bei denen die Dunstabzugsvorrichtung einen DeckenlĆ¼fter darstellt. Bei einer Dunstabzugsvorrichtung, die einen TischlĆ¼fter, der auch als MuldenlĆ¼fter bezeichnet werden kann, darstellt, kƶnnen die in den Figuren gezeigten und oben beschriebenen AusfĆ¼hrungsformen der BetƤtigungsvorrichtungen entsprechend verwendet werden. Die Bewegungsrichtung der Abdeckungen ist bei diesen AusfĆ¼hrungsformen dann entgegengesetzt zu den beschriebenen. Somit wird bei einem TischlĆ¼fter die Abdeckung, die eine Prallplatte darstellt, aus einer Ruheposition in eine Betriebsposition nach oben gedrĆ¼ckt und bei einer Abdeckung, die eine Klappe darstellt, aus einer Ruheposition in eine Betriebsposition nach oben verschwenkt, wobei diese Bewegung jeweils durch ein Federelement oder den Bowdenzug selber erfolgen kann. Die Komponenten der BetƤtigungsvorrichtung sind bei einem TischlĆ¼fter unterhalb der Abdeckung vorgesehen.The invention has been described essentially with reference to embodiments in which the extractor device is a ceiling fan. In an extractor device which is a table ventilator, which may also be referred to as a tray ventilator, the embodiments of the actuators shown in the figures and described above can be used accordingly. The direction of movement of the covers in these embodiments is then opposite to those described. Thus, in a desk ventilator, the cover, which is a baffle plate, is pushed upwardly from a rest position to an operative position and pivoted upwardly from a rest position to an operating position with a cover that is a flap, such movement being either by a spring element or the Bowden cable itself can be done. The components of the actuator are provided at a table fan below the cover.
Mit der vorliegenden Erfindung wird es mƶglich auf einfache Weise bei Dunstabzugshauben, die in der Raumdecke integriert sind oder an der Raumdecke befestigt werden, Prallplatten und Klappen bewegbar auszugestalten. Zur Realisierung dieses Features werden vorzugsweise aufrollbare BowdenzĆ¼ge eingesetzt.With the present invention, it is possible in a simple manner with extractor hoods, which are integrated in the ceiling or attached to the ceiling to design baffles and flaps movable. Roll-up Bowden cables are preferably used to implement this feature.
Stellt die Abdeckung eine Prallplatte dar, kann diese mittels Federelementen in die Aktivstellung bewegt. Beim Ausschalten des GerƤtes wird vorzugsweise durch Zug an den Drahtseilen die Prallplatte in den eingefahrenen Zustand versetzt, der auch als Ruheposition oder Passivstellung bezeichnet werden kann. Vorzugsweise werden in einer Aufwickeleinheit werden die Drahtseile auf einer Rolle aufgewickelt. Die Rolle wird durch einen Motor angetrieben. Um den Einklemmschutz zu verbessern kƶnnen entweder Federn, beispielsweise seriell, in den Innenseilen, die auch als Drahtseile bezeichnet werden kƶnnen, verbaut werden, oder die Rolle wird mittels einer Rutschkupplung auf der Motorwelle befestigt.If the cover is a baffle plate, this can be moved by means of spring elements in the active position. When you turn off the device is preferably offset by train to the wire ropes the baffle plate in the retracted state, which can also be referred to as rest position or passive position. Preferably, in a take-up unit, the wire ropes are wound on a roll. The roller is powered by a motor. To improve the anti-trap protection, either springs, for example serially, can be installed in the inner cables, which can also be referred to as wire ropes, or the roller is fastened on the motor shaft by means of a slip clutch.
Zudem kann die Erfindung auch bei TischlĆ¼ftern eingesetzt werden.In addition, the invention can also be used in desktop fans.
Die Erfindung weist eine Reihe von Vorteilen auf. Durch eine einzige Lƶsung, das heiĆt ein einziges System, werden zwei unterschiedliche Funktionen erfĆ¼llt, insbesondere kann sowohl eine Klappenbewegung als auch eine Prallplattenbewegung realisiert werden, wodurch sich die Varianten der Modelle von Dunstabzugsvorrichtungen reduzieren. Zudem kann bei der vorliegenden Erfindung der Bauraum individuell angepasst werden. Es ist nur ein geringer Bauraum im Frontend der Dunstabzugshaube erforderlich. Daher kann beispielsweise eine leichte Reinigung und leichtes Abklappen der Prallplatte oder der Klappen erfolgen. Zudem kann ein zusƤtzlicher Einklemmschutz bei der vorliegenden Erfindung auf einfache Weise durch zwischengeschaltete Federn oder eine Rutschkupplung realisiert werden. Weiterhin ist eine stufenlose Einstellung der Position der Prallplatten und Klappen mƶglich. Die BetƤtigungsvorrichtung, insbesondere die BowdenzĆ¼ge und eine Aufwickeleinheit sind zudem wartungsfrei, da diese keinen Umwelteinflusse ausgesetzt sind. Zudem besteht kein Performanceverlust der Dunstabzugsvorrichtung, das heiĆt Leistungsverringerung durch konstruktiv bedingte Bauteilpositionierung, da die Bauteile der BetƤtigungsvorrichtung, insbesondere die Aufwickeleinheit wegen der Verwendung von BowdenzĆ¼gen frei positionierbar sind. Durch EndanschlƤge kann die Position, insbesondere die Ruheposition genau definiert und mit hoher Positioniergenauigkeit angefahren werden.The invention has a number of advantages. By a single solution, that is, a single system, two different functions are met, in particular, both a flap movement and a flapper movement can be realized, thereby reducing the variants of the models of extractor devices. In addition, in the present invention, the space can be customized. There is only a small amount of space in the front end of the hood required. Therefore, for example, easy cleaning and easy folding of the flapper or the flaps can be done. In addition, an additional anti-trap in the present invention can be realized in a simple manner by interposed springs or a slip clutch. Furthermore, a continuous adjustment of the position of the baffles and flaps is possible. The actuator, in particular the Bowden cables and a winding unit are also maintenance-free, since they are not exposed to environmental influences. In addition, there is no loss of performance of the extractor device, that is performance reduction due to structurally related component positioning, since the components of the actuator, in particular the winding unit due to the use of Bowden cables are freely positionable. By End stops the position, in particular the rest position can be precisely defined and approached with high positioning accuracy.
