Vorrichtung zum Be- und ggfs. auch Entlüften eines RaumesDevice for ventilation and, if necessary, ventilation of a room
Die Erfindung betrifft eine Vorrichtung zum Be- und ggfs. auch Entlüften eines Raumes mittels Einzeldüsen, welche in einem Gehäusekasten angeordnet sind.The invention relates to a device for ventilating and possibly also venting a room by means of individual nozzles which are arranged in a housing box.
Bekannt sind Düsen, welche als Einzeldüsen entweder durch einen Stellmotor oder von Hand verstellt werden können. Mittels dieser Einzeldüsen wird Warm- oder Kaltluft einem Raum zugeführt. Nachteilig bei diesen Einzeldüsen ist der erheblich Montageaufwand, da jeder Einzeldüse ein Motor zugeordnet werden muß oder aber für jede Einzeldüse die Handverstellung erfolgt. Die Erfinder haben sich zum Ziel gesetzt, eine Vor¬ richtung der o. g. Art zu entwickeln, mittels welcher das Einbringen von Zuluft in einen Raum wesentlich besser gesteuert werden kann und deren Montage erleichtert ist.Nozzles are known which can be adjusted as individual nozzles either by an actuator or by hand. Warm or cold air is fed into a room using these individual nozzles. A disadvantage of these individual nozzles is the considerable assembly effort, since a motor must be assigned to each individual nozzle or manual adjustment is carried out for each individual nozzle. The inventors have set themselves the goal of developing a device of the type mentioned above, by means of which the introduction of supply air into a room can be controlled much better and its assembly is made easier.
Zur Lösung dieser Aufgabe führt, daß zumindest eine Einzeldüse in ein Düsengitter starr eingesetzt und dieses im Verhältnis zu einer Achse des Gehäuses schwenkbar angeordnet ist.The solution to this problem is that at least one individual nozzle is rigidly inserted into a nozzle grille and is arranged pivotably in relation to an axis of the housing.
Zum einen besteht hier der Vorteil, daß die Einzeldüse selbst nicht verstellt werden muß, sondern die Verstellung über das Düsengitter erfolgt. Ferner wird es in der Regel so sein, daß mehrere Einzeldüsen in einem Düsengitter zusammengefaßt sind, so daß bei einer Verstellung des Düsengitters immer mehrere Einzeldüsen verstellt werden. In einem so konzipierten Lüftungs¬ gitter können mehrere Düsengitter mit mehreren Einzel¬ düsen in Einzelreihen oder Folgereihen eingesetz sein. Alle diese Gitter oder nur bestimmte unter ihnen können zusammen über einen Stellmotor gemeinsam verstellt werden. Beispielsweise ist ein Schwenken aus der Längs¬ achse bei einem Wandeinbau des Lüftungsgitters möglich. Werden hier die Düsen in Richtung Raumboden hin geschwenkt, so wird ein Einbringen von Warmluft ver¬ bessert. Verbleiben die Düsenachsen in einer waagrechten Ebene, so dient dieses Lüftungsgitter zum Einbringen von isothermer Luft. Beim Einbringen von Kaltluft dagegen sind die Düsenachsen zur Raumdecke hin gerichtet, so daß keine Zugerscheinungen auftreten. Mit diesem Lüftungsgitter hat ein Betreiber den Vor¬ teil, daß die eintretende frische Luft relativ sicher in das Rauminnere gelangt und der Raum sehr gut durch¬ spült wird. Anhand von entsprechenden Diagrammen kann ein Benutzer der Anlage bzw. ein entsprechender In¬ stallateur feststellen, welche Wurfweiten er mit den Düsen sicher erreicht. Die einzelnen Düsengitter werden mit Düsen auch verschiedenen Düsendurchmessers ge¬ liefert, so daß praktisch jede gewünschte Raumtiefe mit frischer Zuluft problemlos gefüllt werden kann. Selbst¬ verständlich hängt dies auch noch von der zugeführten Luftmenge ab. Die Düsengitter sind sehr leise und können eine beträchtliche Luftmenge auslassen.On the one hand, there is the advantage that the individual nozzle itself does not have to be adjusted, but rather is adjusted via the nozzle grille. Furthermore, it will usually be the case that several individual nozzles are combined in a nozzle grille, so that when the nozzle grille is adjusted, several individual nozzles are always adjusted. In a ventilation grille designed in this way, a plurality of nozzle grilles with a plurality of individual nozzles can be used in individual rows or in subsequent rows. All of these grilles or only certain of them can be adjusted together using a servomotor. For example, swiveling out of the longitudinal axis is possible when the ventilation grille is installed in the wall. If the nozzles are swiveled in the direction of the room floor, the introduction of warm air is improved. If the nozzle axes remain in a horizontal plane, this ventilation grille is used to introduce isothermal air. When cold air is introduced, on the other hand, the nozzle axes are directed towards the ceiling, so that there are no drafts. With this ventilation grille, an operator has the advantage that the incoming fresh air gets into the interior of the room relatively safely and the room is flushed through very well. Using appropriate diagrams, a user of the system or a corresponding installer can determine which throwing distances they can safely reach with the nozzles. The individual nozzle grids are supplied with nozzles of different nozzle diameters, so that practically any desired depth of space can be filled with fresh supply air without any problems. Of course, this also depends on the amount of air supplied. The nozzle grilles are very quiet and can let out a considerable amount of air.
Bevorzugt besteht ein. Düsengitter aus einem Rahmen¬ streifen, welcher den Innenkonturen des Gehäusekastens angepaßt ist. Wird nur ein Schwenk aus der Längsachse des Gehäusekastens gewünscht, so ist dieser Rahmen¬ streifen seitlich nicht festgelegt. Jedoch soll auch ein Drehen des Dusengitters um die Längsachse des Ge¬ häusekastens möglich sein und von dem vorliegenden Erfindungsgedanken umfaßt werden. In diesem Fall besitzt dann der Gehäusekasten eine seitliche Ausbauchung, so daß ein Schwenken des Düsengitters um die Gehäuselängsachse nicht behindert wird.There is preferably a. Nozzle grille from a frame strip which is adapted to the inner contours of the housing box. If only a swivel from the longitudinal axis of the housing box is desired, this frame strip is not laterally fixed. However, it should also be possible to rotate the nozzle grille about the longitudinal axis of the housing box and should be encompassed by the present inventive concept. In this case, the housing box has a lateral bulge, so that pivoting of the nozzle grille around the longitudinal axis of the housing is not hindered.
Der Rahmenstreifen umfängt wiederum bevorzugt Platten, in welche die Einzeldüsen eingesetzt sind und mit denen die Einzeldüsen fest verbunden sind.The frame strip in turn preferably encompasses plates in which the individual nozzles are inserted and with which the individual nozzles are firmly connected.
Im vorliegenden Ausführungsbeispiel ist das Düsengitter über Befestigungslaschen mit dem Gehäusekasten verbunden, wobei diese Befestigungslaschen sich gegen¬ über liegen und eine Drehachse für das Düsengitter bilden. Auf diese Weise kann eine sehr leichte und einfache Verstellung des Düsengitters nach oben oder unten er¬ folgen.In the present exemplary embodiment, the nozzle grille is connected to the housing box via fastening straps, these fastening straps lying opposite one another and forming an axis of rotation for the nozzle grille. In this way, the nozzle grille can be adjusted very easily and simply upwards or downwards.
Für das Schwenken des Düsengitters bietet sich bei¬ spielsweise ein Stellmotor an. Selbstverständlich ist das Schwenken auch manuell möglich, wobei das Düsen¬ gitter bevorzugt in einer bestimmten Lage dann festge¬ legt wird. Relativ viele Einzeldüsen können mittels eines einzigen Antriebes oder manuell verstellt werden, so daß eine hohe Einsparung an Montagekosten und bei der Stomaufnahme gegeben ist.For example, a servomotor is suitable for pivoting the nozzle grille. Of course, pivoting is also possible manually, the nozzle grille then preferably being fixed in a specific position. Relatively many individual nozzles can be adjusted by means of a single drive or manually, so that there is a high saving in assembly costs and in the power consumption.
In einem weiteren Ausführungsbeispiel der Erfindung sind die Düsengitter teilweise auch von Luftschlitzen durchsetzt. Damit ist es möglich, ohne Störung der Zu¬ luft Abluft aus einem Raum abzuziehen. Die Düsen werfen die Zuluft relativ weit in den Raum, so daß kein Kurz¬ schluß, d. h. keine direkte Ableitung der Zuluft ent¬ steht. Bei herkömmlichen Gittern ist die Eintrittsge¬ schwindigkeit zu gering, um eine solche Kombination von Zu- und Abluftgitter zuzulassen.In a further exemplary embodiment of the invention, the air vents are partially penetrated by the air vents. This makes it possible to extract exhaust air from a room without disturbing the supply air. The nozzles throw the supply air relatively far into the room, so that no short circuit, i. H. there is no direct discharge of the supply air. In the case of conventional grilles, the entry speed is too low to permit such a combination of supply and exhaust air grilles.
Selbstverständlich ist dieses erfindungsgemäße Lüftungsgitter sowohl für den Wand- wie auch den Deckeneinbau geeignet. Es kann mit oder ohne Ball¬ schutz in beliebiger Länge bzw. Breite verwendet werden. Weitere Vorteile, Merkmale und Einzelheiten der Er¬ findung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung; diese zeigt iOf course, this ventilation grille according to the invention is suitable for both wall and ceiling installation. It can be used with or without ball protection in any length or width. Further advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawing; this shows i

In the exemplary embodiment according to FIG. 3, the nozzle grille 5a is seated in the region of the bulges 7.
Verbunden mit dem Gehäusekasten 4 bzw. 4a sind die Düsengitter 5 bzw. 5a nur über stirnwärtige Befesti¬ gungslaschen 9, welche eine Bohrung 10 beispielsweise zur Aufnahme einer entsprechenden Schraube oder Niete aufweisen. Diese Bohrungen 10 bilden gleichzeitig ein Schwenklager, wodurch die Neigung des Düsengitters 5 bzw. 5a innerhalb des Gehäusekastens 4 bzw. 4a verändert werden kann.The nozzle grids 5 and 5a are connected to the housing box 4 and 4a only by means of fastening tabs 9 at the end which have a bore 10, for example for receiving a corresponding screw or rivet. These bores 10 simultaneously form a swivel bearing, whereby the inclination of the nozzle grille 5 or 5a can be changed within the housing box 4 or 4a.
Mit dem Rahmenstreifen 8 sind etwa quadratische Platten 12 verbunden, welche eine zentrische Ausnehmung 13 besitzen. In die Ausnehmung 13 sind Einzeldüsen 14 eingesetzt und über entsprechende Schrauben 15 mit der Platte 12 verbunden. Bevorzugt sind mehrere solche Ein¬ zeldüsen 14 für ein Düsengitter 5 vorgesehen.With the frame strip 8 approximately square plates 12 are connected, which have a central recess 13.
