Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zur Zuluftzufuhr zur Verfügung zu stellen, die einfach und kostengünstig ausgebildet ist und darüber hinaus einen erweiterten Anwendungsbereich hat.The object of the present invention is to provide a device for supply air to provide that is simple and inexpensive and above has an expanded scope.

Die zuvor genannte Aufgabe ist bei einer Vorrichtung der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß die Haube als Wirbelhaube ausgebildet ist, innerhalb der sich zwischen voneinander beabstandeten Absaugbereichen während des Absaugbetriebes eine Drallströmung ausbildet, daß eine die Haubenöffnung im Zuluftbetrieb überdeckende Klappe vorgesehen ist, daß in der Klappe mit der Haubenöffnung kommunizierende Öffnungen vorgesehen sind, daß die Klappe die Haubenöffnung im Absaugbetrieb freigebbar ist und daß die Klappe über ein Scharnier an der Haube angelenkt ist, so daß die Klappe im Absaugbetrieb in eine die Haubenöffnung freigebende Freigabestellung verschwenkbar ist, wobei die Breite der Klappe ein Mehrfaches der Breite der Haubenöffnung ist, so daß die in die Freigabestellung geschwenkte Klappe als Rauchschürze dient. Die Erfindung bietet eine Reihe von zum Teil wesentlichen Vorteilen. Zunächst einmal ist sowohl zur Zuluftzufuhr als auch zum Absaugen nur noch eine einzige Vorrichtung erforderlich. Dabei übernimmt die Haube eine Doppelfunktion. Einerseits dient sie während der Zuluftzufuhr zur Verteilung der Zuluft, während sie andererseits beim Absaugen zur Erzeugung der Drallströmung dient. Die Erfindung betrifft also letztlich vom Grundsatz her den Einsatz einer an sich bekannten Wirbelhaube zu Brandschutzzwecken, d. h. um Rauch und Wärme - also erwärmte Luft - im Brandfall aus einem Gebäude, insbesondere einem Wohn- oder Bürogebäude abzusaugen. Hierzu ist konkret eine Rauch- und/oder Brandmeldeeinrichtung vorgesehen, die mit der Vorrichtung gekoppelt ist. Lediglich bei Aktivierung der Rauch- und/oder Brandmeldeeinrichtung, d. h. also bei Feststellung eines Brandfalles, wird über eine entsprechende Steuereinrichtung die Absaugeinrichtung eingeschaltet, so daß über die Haube Luft aus dem Gebäude abgesaugt wird.In a device, the aforementioned task is the one mentioned at the beginning Art solved according to the invention in that the hood as a swirl hood is formed within the spaced apart Suction areas forms a swirl flow during the suction operation, that a flap covering the hood opening in the supply air operation is provided is that provided in the flap with the hood opening communicating openings are that the flap the hood opening can be released in suction is and that the flap is hinged to the hood so that the Flap in suction mode in a release position that releases the hood opening is pivotable, the width of the flap being a multiple of the width the hood opening, so that the flap pivoted into the release position serves as a smoke apron. The invention offers a number of partly essential Benefits. First of all, both for supply air and for suction only one device required. The Hood double function. On the one hand, it is used during the supply air supply Distribution of the supply air, while on the other hand it is used for extraction to generate serves the swirl flow. The invention therefore ultimately relates to the principle the use of a swirl hood known per se for fire protection purposes, d. H. for smoke and heat - i.e. heated air - in the event of a fire from a building, especially to vacuum a residential or office building. This is concrete a smoke and / or fire detection device provided with the device is coupled. Only when the smoke and / or fire alarm device is activated, d. H. So if a fire is detected, a corresponding Control device switched on the suction device, so that on the Hood air is sucked out of the building.

Hinsichtlich der Funktionsweise der Wirbelhaube im einzelnen wird der Einfachheit halber auf die DE 39 01 859 A1 und die DE 42 43 834 A1 verwiesen, in denen das Prinzip und die Wirkungsweise der Wirbelhaube im einzelnen beschrieben und gezeigt sind. Die diesbezüglichen Ausführungen hinsichtlich der Betriebsweise und des Aufbaus der Wirbelhaube werden insofern zum Gegenstand der vorliegenden Anmeldung gemacht.Regarding the functioning of the swirl hood in detail, the simplicity for the sake of reference to DE 39 01 859 A1 and DE 42 43 834 A1, in which described the principle and mode of operation of the vertebral hood in detail and are shown. The relevant statements regarding the The mode of operation and the construction of the swirl hood are thus the subject made the present application.

Neben der für den Zuluft- und den Absaugbetrieb gemeinsamen Haube kann grundsätzlich auch nur ein einziges Gebläse vorgesehen sein, das einerseits die Zuluft zuführt und andererseits zum Absaugen in entgegengesetzter Richtung betrieben wird. Grundsätzlich ist es aber auch möglich, einerseits ein Gebläse und andererseits eine als Entrauchungsventilator ausgebildete Absaugeinrichtung zu verwenden. Entscheidend ist vorliegend, daß bei Detektion eines Brandfalles über die Rauch- und/oder Brandmeldeeinrichtung unverzüglich die Zuluftzufuhr in das Gebäude gestoppt und dann mit der Absaugung über die Absaugeinrichtung und die Haube begonnen wird. Der Ablauf im einzelnen wird über eine Steuereinrichtung gesteuert.In addition to the hood that is common for the supply air and suction operation in principle, only a single blower can be provided, which on the one hand the Supply air supplies and on the other hand for suction in the opposite direction is operated. Basically, it is also possible, on the one hand, a blower and on the other hand a suction device designed as a smoke extraction fan to use. What is decisive here is that when a fire is detected The supply air supply immediately via the smoke and / or fire detection device stopped in the building and then with the suction via the suction device and the hood is started. The process in detail is about controlled a control device.

Wichtig ist in diesem Zusammenhang und als Unterschied zum Stand der Technik, daß nicht nur eine Absaugeinrichtung als solche zur Absaugung verwendet wird, sondern eine Wirbelhaube der zuvor angegebenen Art. Eine derartige Wirbelhaube zeichnet sich durch eine sehr gute Saugwirkung und -leistung aus, die aufgrund des hohen dynamischen Überdruckes wegen der hohen Umfangsgeschwindigkeit der Drallströmung in der Haube einen entsprechend niedrigen statischen Druck und eine entsprechend hohe Saugleistung zur Folge hat.It is important in this context and as a difference to the state of the art, that not only used a suction device as such for suction is, but a swirl hood of the type specified above. Such a swirl hood is characterized by a very good suction effect and performance, the due to the high dynamic overpressure due to the high peripheral speed the swirl flow in the hood has a correspondingly low static Pressure and a correspondingly high suction power.

In der Klappe sind erfindungsgemäß in die Haubenöffnung mündende Öffnungen vorgesehen. Die Öffnungen können dabei als Rundöffnungen oder Lüftungsschlitze ausgebildet sein. Auch ist es möglich, eine zumindest bereichsweise perforierte Klappe zu verwenden, wobei die Perforation derart ist, daß Lüftungsöffnungen an sich nicht sichtbar sind, ein Luftdurchtritt aber dennoch möglich ist. Die vorgenannte Ausgestaltung bietet zunächst einmal optischästhetische Vorteile, da die Klappe die Haubenöffnung überdeckt, ein unmittelbarer Einblick in die Haube also nicht möglich ist. Während es bei Wirbelhauben der in Rede stehenden Art beim industriellen Einsatz nicht auf optischästhetische Aspekte ankommt, ist dies beim Einsatz in Wohn- oder Bürogebäuden anders. Optisch-ästhetischen Einflüssen kommt eine ganz besondere Bedeutung zu. Daher ist erfindungsgemäß eine die Haubenöffnung, die dem Betrachter den Einblick in die Wirbelhaube ermöglicht, im nicht aktivierten Zustand bzw. im Zuluftbetrieb überdeckende Klappe vorgesehen, wobei die Klappe die Haubenöffnung nur im Absaugbetrieb zumindest im wesentlichen freigibt. Durch diese Ausgestaltung ist sichergestellt, daß eine beispielsweise in einer abgehängten Decke angeordnete erfindungsgemäße Vorrichtung von außen quasi nicht erkennbar ist. Die in den Raum gerichtete Haubenöffnung ist im Zuluftbetrieb über die Klappe abgedeckt. Erst im Absaugbetrieb erfolgt die Freigabe der Haubenöffnung über die Klappe. Darüber hinaus kann der Zuluft zumindest bei der Verwendung von Lüftungsschlitzen eine bestimmte Ausrichtung gegeben werden. Dabei versteht es sich, daß die Lüftungsschlitze dann beispielsweise über entsprechende Lamellen verstellbar sind.According to the invention, openings in the flap open into the hood opening intended. The openings can be round openings or ventilation slots be trained. It is also possible, at least in some areas to use perforated flap, the perforation being such that Ventilation openings are not visible per se, but air passage is nevertheless is possible. The aforementioned embodiment first of all offers an aesthetic appearance Advantages, since the flap covers the hood opening, are immediate Insight into the hood is not possible. While it is with pegs of the type in question in industrial use not optically aesthetic Aspects, this is when used in residential or office buildings different. Optical-aesthetic influences have a very special meaning to. Therefore, according to the invention, the hood opening is for the viewer provides an insight into the swirl hood when not activated or provided in the supply air mode overlapping flap, the flap the hood opening only at least essentially releases in the suction mode. This configuration ensures that, for example, in a suspended Device according to the invention arranged from the ceiling, so to speak, from the outside is not recognizable. The hood opening directed into the room is in the supply air mode covered over the flap. The release of the Hood opening over the flap. In addition, the supply air can at least given a certain orientation to the use of ventilation slots become. It goes without saying that the ventilation slots are then, for example are adjustable via appropriate slats.

Während es für den Zuluftbetrieb darauf ankommt, die Zuluft über die verstellbaren Lüftungsschlitze entsprechend im Raum zu verteilen, ist es im Absaugbetrieb erforderlich, daß die Haubenöffnung frei zugänglich ist, damit eine möglichst große Menge an Rauch und Wärme abgesaugt werden kann. Zwar ist es grundsätzlich auch möglich, über die Lüftungsschlitze Luft abzusaugen, jedoch ergibt sich eine verbesserte Saugleistung, wenn die Haubenöffnung frei zugänglich ist. Aus diesem Grunde ist erfindungsgemäß vorgesehen, daß die Klappe die Haubenöffnung im Absaugbetrieb zumindest im wesentlichen freigibt. Um die Haubenöffnung im Brandfalle freizugeben, ist es erfindungsgemäß vorgesehen, die Klappe von der Haube herabfallen zu lassen oder aber so weit zu verschieben, daß die Haubenöffnung freigegeben wird. Die Klappe ist über ein Scharnier an der Haube angelenkt, so daß die Klappe im Absaugbetrieb in eine die Haubenöffnung im wesentlichen freigebende Freigabestellung schwenkt. Durch die Anlenkung der Klappe ist zunächst einmal sichergestellt, daß bei einem Fehlalarm die aufgeschwenkte Klappe ohne weiteres in den Verschlußzustand zurückgeschwenkt werden kann. Die zuvor genannte Ausgestaltung der angelenkten Klappe bietet sich aber insbesondere dann an, wenn die in die Freigabestellung geschwenkte Klappe als sogenannte Rauchschürze dient. Zweck einer derartigen Rauchschürze ist es, ein Überschlagen insbesondere von Rauch an der Wirbelhaube vorbei zu verhindern. Um diese Aufgabe wirksam erfüllen zu können, weist die Breite der Klappe ein Mehrfaches der Breite der Haubenöffnung auf, so daß die Klappe im herabgeschwenkten Zustand vergleichsweise weit in den Raum hineinragt und dadurch die Rauchschürzenfunktion erfüllen kann.While it is important for the supply air operation, the supply air via the adjustable To distribute ventilation slots in the room accordingly, it is in suction mode required that the hood opening is freely accessible so that a the largest possible amount of smoke and heat can be extracted. Although is in principle it is also possible to extract air through the ventilation slots, however there is an improved suction power if the hood opening is freely accessible is. For this reason, the invention provides that the flap the hood opening in suction mode at least essentially releases. In order to release the hood opening in the event of a fire, the invention provides to let the flap fall off the hood or so far move that the hood opening is released. The flap is over a Hinge hinged to the hood so that the flap in a suction the hood opening pivots release position substantially. The articulation of the flap first ensures that one False alarm the opened flap easily in the locked state can be pivoted back. The aforementioned configuration of the hinged flap is particularly useful when in the release position swiveled flap serves as a so-called smoke apron. Purpose one Such a smoke apron is a flashover especially from smoke to prevent the swirl hood from passing. To accomplish this task effectively can, the width of the flap is a multiple of the width of the hood opening on, so that the flap in the swung-down state is comparatively protrudes far into the room and thereby fulfills the smoke apron function can.

Gerade bei Verwendung einer als Rauchschürze dienenden Klappe, deren Fläche erheblich größer ist als die Fläche der Haubenöffnung, kann es sich anbieten, die Zuluftöffnungen im wesentlichen über die gesamte Fläche der Klappe anzuordnen. Hierdurch kann in einfacher Weise einem vergleichsweise großen Bereich ohne weiteres Frischluft zugeführt werden. In diesem Falle versteht es sich natürlich, daß die Anordnung derart gewählt sein muß, daß im Zuluftbetrieb die Zuluft auch über die gesamte Fläche der Klappe austreten kann.Especially when using a flap serving as a smoke apron, its surface is considerably larger than the area of the hood opening, it can offer that Inlet air openings to be arranged essentially over the entire surface of the flap. This allows a comparatively large area in a simple manner fresh air can be supplied without further notice. In this case, it goes without saying that the arrangement must be selected such that the Supply air can also escape over the entire surface of the flap.

Des weiteren ist, auch aus optisch-ästhetischen Gründen, vorgesehen, daß die Klappe einen verlängerten und insbesondere das Scharnier in Verschlußstellung abdeckenden Abschnitt aufweist, der während des Schwenkens der Klappe auf die Haube zuschwenkt. Aufgrund dieser besonderen Klappenausbildung ist zum einen von außen nicht erkennbar, daß überhaupt ein Scharnier vorgesehen ist, also die Klappe herausschwenken kann. Zum anderen schlägt dieser Abschnitt während des Absaugbetriebes an der Haube an, so daß ein Schwenken über eine vorgegebene Stellung hinaus nicht möglich ist.Furthermore, it is provided, also for optical-aesthetic reasons, that the Fold an extended and in particular the hinge in the closed position covering portion, which during the pivoting of the flap the hood swings shut. Because of this special flap design is for one not recognizable from the outside that a hinge is provided at all, that is can swing the flap out. On the other hand, this section beats during the suction operation on the hood, so that pivoting over a specified position is not possible.

Um das Herabschwenken der Klappe im Brandfalle in einfacher Weise zu realisieren, ist eine mit der Rauch- und/oder Brandmeldeeinrichtung gekoppelte Halteeinrichtung zur Halterung der Klappe in der Verschlußstellung vorgesehen. Spricht die Rauch- und/oder Brandmeldeeinrichtung an, wird die Klappe von der Halteeinrichtung ggf. über die zwischengeschaltete Steuereinrichtung freigegeben.To easily swing the flap down in the event of a fire, is a holding device coupled to the smoke and / or fire detection device provided for holding the flap in the closed position. If the smoke and / or fire alarm device responds, the flap of the Holding device released if necessary via the intermediate control device.

Bei einer besonders einfachen und bevorzugten Ausgestaltung weist die Halteeinrichtung wenigstens einen Elektromagneten auf, der im Brandfalle stromlos geschaltet wird. Dabei versteht es sich, daß entweder die Klappe selbst magnetisch ist oder aber entsprechende magnetische Teile an der Klappe zum Zusammenwirken mit den Elektromagneten vorgesehen sind.In a particularly simple and preferred embodiment, the holding device has at least one electromagnet, which is de-energized in the event of a fire is switched. It goes without saying that either the flap itself is magnetic is or corresponding magnetic parts on the flap to cooperate are provided with the electromagnets.

Grundsätzlich ist es möglich, daß die erfindungsgemäße Vorrichtung nur eine einzige Haube aufweist. Um die erfindungsgemäße Vorrichtung an unterschiedlichste Anwendungsfälle in einfacher Weise anpassen zu können, ist darüber hinaus vorgesehen, daß für einzelne Anwendungsfälle nicht unterschiedlich lange Hauben verwendet werden, sondern daß an sich nur ein Grundtyp von Haube als Basismodul verwendet wird. Dies vereinfacht die Herstellung und senkt die Herstellungskosten. Je nach Anwendungsfall werden eine Mehrzahl von Hauben als Module verwendet, wobei die einzelnen Module dann über die gewünschte Gesamtlänge miteinander verbunden werden. Die direkte Verbindung der einzelnen Module führt dann dazu, daß sich fast über die gesamte Länge der sich aus mehreren Modulen zusammensetzenden Gesamthaubenvorrichtung eine wirksame Absaugung stattfinden kann.Basically, it is possible that the device according to the invention only one has only hood. To the device according to the invention to the most varied It is about being able to adapt use cases in a simple way also provided that not different for individual applications long hoods are used, but that in itself only a basic type of Hood is used as a basic module.

In Fig. 1 ist ein Teil eines Gebäudes 1 dargestellt, das eine Vorrichtung zur Zuluftzufuhr aufweist. Bei dem Gebäude 1 handelt es sich vorliegend um ein Wohn- oder ein Bürogebäude. Die Vorrichtung selbst weist wenigstens ein Gebläse auf, das vorliegend nicht dargestellt ist. Des weiteren ist die Vorrichtung mit wenigstens einer Haube 2 zur Abgabe der Zuluft an das Gebäude 1 versehen. Die Haube 2 ist dabei über entsprechende Zuluftleitungen mit dem nicht dargestellten Gebläse verbunden. Wie sich insbesondere aus Fig. 1 ergibt, weist die Haube 2 eine in das Gebäude 1 gerichtete Haubenöffnung 3 auf.In Fig. 1 a part of a building 1 is shown, the device for supply air having. Building 1 is a Residential or office building. The device itself has at least one blower on, which is not shown here. Furthermore, the device provided with at least one hood 2 for supplying the supply air to the building 1. The hood 2 is connected to the supply air lines with the not shown Fan connected. As can be seen in particular from FIG. 1, the Hood 2 has a hood opening 3 directed into building 1.

Wesentlich ist nun zunächst, daß eine mit der Haube 2 verbundene, nicht dargestellte Absaugeinrichtung vorgesehen ist. Bei der Absaugeinrichtung handelt es beispielsweise um einen mechanischen Entrauchungsventilator, der über entsprechende Leitungen mit der Haube 2 verbunden ist. Dabei können zum Teil auch die Zuluftleitungen verwendet werden. Wesentlich ist weiterhin, daß die Haube 2 als sogenannte Wirbelhaube ausgebildet ist, innerhalb der sich zwischen zwei voneinander beabstandeten Absaugbereichen während des Absaugbetriebes eine Drallströmung ausbildet. Nicht dargestellt ist, daß die Haube eine Mehrzahl von Absaugbereichen aufweist, so daß sich innerhalb der Wirbelhaube auch eine Mehrzahl von Wirbeln ausbilden kann. It is now essential that one connected to the hood 2, not shown Suction device is provided. The suction device is for example, a mechanical smoke extraction fan, which has appropriate Lines are connected to the hood 2. In some cases, too the supply air lines are used. It is also essential that the hood 2 is designed as a so-called vortex hood, within which there is between two suction areas spaced apart from one another during the suction operation Swirl flow forms. It is not shown that the hood has a plurality of Has suction areas, so that there is also a within the vortex hood Can form a plurality of vertebrae.

Schließlich ist noch vorgesehen und für die Erfindung wesentlich, daß die Vorrichtung über eine ebenfalls nicht dargestellte Steuereinrichtung mit einer Rauchund/oder Brandmeldeeinrichtung (nicht dargestellt) derart gekoppelt ist, daß bei Aktivieren der Rauch- und/oder Brandmeldeeinrichtung einerseits die Zuluftzufuhr in das Gebäude 1 unterbrochen und andererseits über die Haube 2 und die nicht dargestellte Absaugeinrichtung Raumluft und damit im Brandfall Rauch und Wärme abgesaugt wird. Zur Absaugung dient zumindest teilweise die gleiche Leitung wie zur Zuluftzuführung.Finally, it is provided and essential for the invention that the device via a control device, also not shown, with a smoke and / or Fire detection device (not shown) is coupled such that at Activating the smoke and / or fire detection device on the one hand the supply air supply interrupted in the building 1 and on the other hand via the hood 2 and the Suction device, not shown, room air and therefore smoke in the event of fire and heat is extracted. The same is used for suction at least in part Line as for the supply air supply.

In Fig. 1 ist dabei im oberen Teil der Darstellung der Normalbetrieb, also die Zuluftzufuhr dargestellt, während im unteren Teil der Absaugbetrieb, also die Absaugung von Raumluft über die Haube 2 dargestellt ist. Es ist allerdings darauf hinzuweisen, daß in einem Brandfalle nicht auf einer Etage abgesaugt wird, während auf der darüber liegenden Etage weiterhin Zuluft zugeführt wird. Im Brandfalle nehmen alle Hauben 2, die in dem Gebäude 1 vorgesehen sind, den im unteren Teil der Fig. 1 gezeigten Zustand, auf den nachfolgend noch näher eingegangen wird, ein.In Fig. 1 is in the upper part of the representation of normal operation, that is Supply air supply shown, while in the lower part of the suction operation, i.e. the Extraction of room air through the hood 2 is shown. However, it is on it to point out that in the event of a fire, suction is not carried out on one floor, while supply air continues to be supplied on the floor above. in the Fire traps remove all hoods 2 that are provided in building 1 in the lower part of FIG. 1, to the following in more detail is received, a.

Wie sich insbesondere aus den Fig. 2 und 3 ergibt, ist eine die Haubenöffnung 3 im Zuluftbetrieb, der insbesondere in Fig. 2 gut dargestellt ist, überdeckende Klappe 4 vorgesehen. Dabei weist die Klappe 4 eine Mehrzahl von vorliegend als Lüftungsschlitze 5 ausgebildeten Öffnungen auf, die über entsprechende Lamellen 6 voneinander getrennt sind. Die Lamellen 6 sind dabei verstell- bzw. verschwenkbar, so daß die Ausströmrichtung der Zuluft über die Stellung der Lamellen gesteuert werden kann.As can be seen in particular from FIGS. 2 and 3, one is the hood opening 3 in supply air operation, which is particularly well shown in FIG. 2, overlapping Flap 4 provided. The flap 4 has a plurality of present formed as ventilation slots 5 openings that have corresponding slats 6 are separated. The slats 6 are adjustable or pivotable so that the outflow direction of the supply air on the position of the Slats can be controlled.

Bei der in Fig. 4 dargestellten Ausführungsform weist die Klappe 4 zumindest über die gesamte Breite B der Haube 2 Lüftungsöffnungen auf, die vorliegend wiederum als Lüftungsschlitze ausgebildet sind. Gegenüber der Ausführungsform gemäß Fig. 2 ist der eigentliche Wirbelhaubenkanal 2a nach oben versetzt, so daß sich zwischen der den eigentlichen Wirbelhaubenkanal 2a begrenzenden Blende 2b und der Klappe 4 ein Zwischenraum 4a ergibt, über den über die Haube 2 zugeführte Zuluft nicht nur im Bereich der Haubenöffnung 3, sondern auch im Bereich des Zwischenraumes 4a austritt.In the embodiment shown in FIG. 4, the flap 4 has at least over the entire width B of the hood 2 ventilation openings, the present are in turn designed as ventilation slots. Compared to the embodiment 2 the actual vertebral canal 2a is displaced upwards, so that between the actual vertebral canal 2a delimit Aperture 2b and the flap 4 results in a space 4a over the the hood 2 supplied air not only in the area of the hood opening 3, but also emerges in the area of the intermediate space 4a.

Wie sich insbesondere aus Fig. 3 ergibt, gibt die Klappe 4 die Haubenöffnung 3 im Absaugbetrieb frei. Die Klappe 4 ist dabei über ein Scharnier 9 an der Haube 2 angelenkt. Über das Scharnier 9 ist es möglich, daß die Klappe 4 aus der in Fig. 2 dargestellten Position im Zuluftbetrieb in die in Fig. 3 dargestellte Stellung im Absaugbetrieb schwenkt. Im Absaugbetrieb ergibt sich dabei innerhalb der Haube 2 eine Drallströmung 7, die in eine sehr hohe Umfangsgeschwindigkeit und einen entsprechend hohen dynamischen Druck mit einem damit verbundenen geringen statischen Druck erzeugt. Der statische Unterdruck im Bereich der Wirbelhaube sorgt für ein Ansaugen der Raumluft, wie dies durch die Pfeile 8 in Fig. 3 dargestellt ist.As can be seen in particular from FIG. 3, the flap 4 gives the hood opening 3 free in suction mode. The flap 4 is on a hinge 9 on the hood 2 hinged. About the hinge 9, it is possible that the flap 4 from the in Fig. 2 shown position in the supply air mode in the position shown in Fig. 3 swivels in suction mode. In suction mode, this results in the Hood 2 a swirl flow 7, which is in a very high peripheral speed and a correspondingly high dynamic pressure with an associated generates low static pressure. The static vacuum in the area of The swirl hood ensures that the room air is sucked in, as indicated by the arrows 8 in Fig. 3 is shown.

Wie sich weiterhin insbesondere aus den Fig. 2 und 3 ergibt, weist die Breite B der Klappe 4 ein Mehrfaches der Breite b der Haubenöffnung 3 auf, so daß die in die Freigabestellung geschwenkte Klappe 4 als Rauchschürze dient. Diese Funktion der Klappe 4 ergibt sich auch aus dem unteren Teil der Darstellung gemäß Fig. 1.As can further be seen in particular from FIGS. 2 and 3, the width B the flap 4 a multiple of the width b of the hood opening 3, so that the in the release position pivoted flap 4 serves as a smoke apron. this function the flap 4 also results from the lower part of the illustration Fig. 1.

Die Klappe 4 weist im übrigen einen das Scharnier 9 in Verschlußstellung abdeckenden Abschnitt 10 auf, der während des Schwenkens der Klappe 4 auf die Haube 2 zuschwenkt. Im in Fig. 3 dargestellten Zustand liegt der Abschnitt 10 an der Haube 2 an, was zur Folge hat, daß ein weiteres Aufschwenken der Klappe 4 als im Fig. 3 dargestellten Zustand nicht möglich ist.The flap 4 also has a hinge 9 covering the closed position Section 10, which during the pivoting of the flap 4 on the Hood 2 swings shut. In the state shown in Fig. 3, the section 10 is present the hood 2, which has the consequence that a further pivoting of the flap 4th as shown in Fig. 3 is not possible.

Weiterhin ist eine mit der Rauch- und/oder Brandmeldeeinrichtung gekoppelte Halteeinrichtung 11 vorgesehen, die zur Halterung der Klappe 4 in Verschlußstellung, die in Fig. 2 dargestellt ist, dient. Im einzelnen weist die Halteeinrichtung 11 wenigstens einen Elektromagneten 12 auf, der bei Aktivieren der Rauch- und/oder Brandmeldeeinrichtung stromlos geschaltet wird. Dies hat zur Folge, daß die Klappe 4 nicht mehr über den Elektromagneten 12 gehalten wird und aus der in Fig. 2 dargestellten Stellung in die in Fig. 3 dargestellte Stellung schwenkt.Furthermore, one is coupled to the smoke and / or fire detection device Holding device 11 is provided, which for holding the flap 4 in the closed position, which is shown in Fig. 2 is used. In detail, the holding device 11 at least one electromagnet 12, which when activated the smoke and / or fire alarm device is switched off. this has with the result that the flap 4 is no longer held over the electromagnet 12 and from the position shown in FIG. 2 to that shown in FIG. 3 Position pivots.

Wie sich nun wieder aus Fig. 1 ergibt, sind die einzelnen Hauben 2 benachbart eines Atriums 13 des Gebäudes 1 angeordnet. Die Anordnung der einzelnen Hauben 2 ist aber im übrigen derart, daß die Hauben 2 in abgehängten Decken 14 angeordnet sind und zwar derart, daß die Außenseite der jeweiligen Haube 2, und damit vorliegend die Außenseite der jeweiligen Klappe 4, mit der abgehängten Decke 14 ausgefluchtet ist. Die Anordnung der einzelnen Hauben 2 insbesondere im Hinblick auf die Anlenkung der jeweiligen Klappen 4 ist dabei derart, daß die Klappen 4 im Brandfall zum Atrium 13 hin schwenken und damit die zuvor bereits angesprochene Rauchschürzenfunktion erfüllen.1, the individual hoods 2 are adjacent an atrium 13 of the building 1. The arrangement of each Hoods 2 is otherwise such that the hoods 2 in suspended ceilings 14 are arranged in such a way that the outside of the respective hood 2, and thus in the present case the outside of the respective flap 4, with the suspended one Blanket 14 is aligned. The arrangement of the individual hoods 2 in particular with regard to the articulation of the respective flaps 4 such that the flaps 4 pivot towards the atrium 13 in the event of a fire and thus fulfill the previously mentioned smoke apron function.
