Description

Die Erfindung betrifft einen Drallauslaß mit einer Ausblasplatte und in dieser vorgesehenen Ausblasöffnungen für Warm- und/oder Kaltluft, welchen jeweils eine individuell zu regelnde Luftstrahlleitlamelle zugeordnet ist.The invention relates to a swirl outlet with a blow-out plate and blow-out openings provided in this for hot and / or cold air, to which an individually adjustable air jet guide lamella is assigned.

Derartige Drallauslässe sind insbesondere als Deckendrallauslässe in vielfältiger Form bekannt. Durch sie wird Warm- und/oder Kaltluft in einen Raum eingeleitet, wobei diese Luft durch entsprechende Kanäle bzw. Schächte herbeigeführt wird.Swirl outlets of this type are known in various forms in particular as ceiling swirl outlets. Through them, warm and / or cold air is introduced into a room, this air being introduced through corresponding channels or shafts.

Beim Luftaustritt stellt sich immer wieder das Problem, daß dieser Luftaustritt für bestimmte Räume, Raumhöhen und Verwendungsbereiche anders ausgestaltet sein sollte. In einem Fall sollte mehr Luft schneller direkt senkrecht in den Raum eingebracht werden, während im anderen Fall beispielsweise ein Warmluftaufbau parallel zur Decke von oben nach unten erfolgen kann. Jeder Raum erfordert im Grunde genommen seinen eigenen Drallauslaß, damit die Luftführung optimiert wird.With the air outlet, the problem arises again and again that this air outlet should be designed differently for certain rooms, room heights and areas of use. In one case, more air should be introduced directly vertically into the room faster, while in the other case, for example, warm air can be built up parallel to the ceiling from top to bottom. Basically, each room requires its own swirl outlet to optimize airflow.

Aus der FR-A 2 313 641 ist beispielsweise ein Auslaß der o.g. Art bekannt. Nachteilig hat sich bei diesen Auslässen herausgestellt, daß die Luftzuführung immer nur senkrecht oder schräg von oben nach unten erfolgt.From FR-A 2 313 641, for example, an outlet of the above. Kind known. It has turned out to be disadvantageous with these outlets that the air supply is always only vertical or oblique from top to bottom.

In einem anderen Lüftungssystem entsprechend der DE-U 87 00 243. 4 sind dagegen eine Reihe von mit Lamellen belegten Schlitzauslässen an einem Rohr angeordnet, was jedoch sehr aufwendig ist und für eine Decke nicht geeignet erscheint, da das Rohr unterhalb der Decke in dem Raum angeordnet werden muß.In another ventilation system according to DE-U 87 00 243.4, on the other hand, a series of slit outlets covered with lamellae are arranged on a pipe, which is very complex and does not appear to be suitable for a ceiling, since the pipe is below the ceiling in the room must be arranged.

Die Erfinder haben sich zum Ziel gesetzt, einen Drallauslaß der o.g. Art zu entwickeln, bei dem eine derartige individuelle Regelung möglich ist, wobei der Drallauslaß als Deckenauslaß Anwendung finden kann.The inventors set themselves the goal of creating a swirl outlet of the above. Develop type in which such individual control is possible, the swirl outlet can be used as a ceiling outlet.

Zur Lösung dieser Aufgabe führt, daß der Ausblasplatte Seitenwände aufgesetzt sind, welche Seitenschlitze aufweisen, die ebenfalls von Luftstrahlleitlamellen besetzt sind.To achieve this object, the blow-out plate is fitted with side walls which have side slots which are also occupied by air jet guide blades.

Wenn beispielsweise die Ausblasöffnung quadratisch ausgestaltet ist, so kann sie durch entsprechende Diagonalen in vier Ausblasflächen aufgeteilt werden. Jede dieser Ausblasflächen besitzt Auslaßöffnungen, wobei längsachsenbenachbarte Auslaßöffnungen rechtwinklig zueinander verlaufen.If, for example, the blow-out opening is square, it can be divided into four blow-out areas by appropriate diagonals. Each of these blow-out surfaces has outlet openings, with outlet openings adjacent to the longitudinal axis being at right angles to one another.

Hierdurch teilt der Drallauslaß den Luftstrom in vier einzelne Ausblasströme auf, wie dies früher auch mit anderen Deckenauslässen der herkömmlichen Art möglich war.As a result, the swirl outlet divides the air flow into four individual outlet flows, as was previously possible with other ceiling outlets of the conventional type.

Da aber erfindungsgemäß jeder Auslaßöffnung eine extra Luftstrahlleitlamelle zugeordnet ist, kann der Ausblasstrom nach allen vier Seiten individuell ausgelegt werden.However, since according to the invention an extra air jet guide lamella is assigned to each outlet opening, the blow-out flow can be designed individually on all four sides.

In einem extremen Fall schlägt die Luftstrahlleitlamelle mit einer Kante an einem Rand der Auslaßöffnung an, so daß der Ausblasstrom etwa in einem Winkel von 45° sich verbreiternd von der Ausblasplatte weggeführt wird. In der entgegengesetzten Gebrauchslage schlägt die Luftstrahlleitlamelle an der gegenüberliegenden Kante der Auslaßöffnung an, so daß der Ausblasstrom um etwa 90° versetzt aus der Auslaßöffnung geleitet wird. Dazwischen sind selbstverständlich andere Stellungen der Luftstrahlleitlamelle möglich.In an extreme case, the air jet guide lamella strikes an edge at an edge of the outlet opening, so that the blow-out stream is widened away from the blow-out plate at an angle of approximately 45 °. In the opposite position of use, the air jet guide lamella strikes the opposite edge of the outlet opening, so that the blow-out stream is conducted out of the outlet opening offset by approximately 90 °. In between, other positions of the air jet guide lamella are of course possible.

Durch diese Ausgestaltung ist es möglich, beispielsweise in der Mitte des Drallauslasses einen gezielten Senkrechtstrahl zu erreichen, um schwerpunktmäßig die Zuluft schnell in einen Raum einzubringen. Mit den dagegen weiter außen liegenden Lamellen kann die Zuluft schräg im Raum nach außen hin verteilt werden. Dies soll jedoch nur ein Ausführungsbeispiel sein. Es ist leicht ersichtlich, daß durch die individuelle Regelung der Luftstrahlleitlamellen eine noch viel stärkere Differenzierung der Ausblasströme ermöglicht ist. Beispielsweise kann einer der vier Ausblasströme stärker nach unten und ein anderer dagegen stärker zur Mitte hin gelenkt sein.This configuration makes it possible, for example, to achieve a targeted vertical jet in the middle of the swirl outlet in order to quickly introduce the supply air into a room. On the other hand, with the fins located further outside, the supply air can be distributed diagonally outwards in the room. However, this is only intended to be an exemplary embodiment. It is easy to see that the individual regulation of the air jet guide fins enables a much stronger differentiation of the blow-out flows. For example, one of the four blow-out streams can be directed more downwards and another can be directed more towards the center.

Da auch die Seitenwände entsprechende Auslaßöffnungen besitzen, die wiederum jeweils von einer individuell zu regelnden Luftstrahlleitlamelle besetzt sind, kann die Zuluft entweder an der Decke entlang oder gezielt schräg nach unten ausgebracht werden.Since the side walls also have corresponding outlet openings, which in turn are each occupied by an individually controllable air-jet guide lamella, the supply air can either be discharged along the ceiling or selectively at an angle downwards.

Sollte es wünschenswert erscheinen, kann die Höhe der Seitenwand vergrößert werden, so daß hier auch zwei oder drei Auslaßöffnungen übereinander vorgesehen werden können. Hierdurch besitzt der Drallauslaß einen sehr hohen freien Querschnitt, so daß geräuscharm sehr viel Luft gezielt in einen Raum eingebracht werden kann.Should it appear desirable, the height of the side wall can be increased so that two or three outlet openings can also be provided one above the other. As a result, the swirl outlet has a very high free cross-section, so that a lot of air can be introduced into a room with little noise.

Für die Größe des Auslasses bestehen keine Beschränkungen. Vorgesehen sind Auslässe mit einer Größe von 300 x 300 bis 1000 x 1000 mm.There are no restrictions on the size of the outlet. Outlets with a size of 300 x 300 to 1000 x 1000 mm are provided.

Ein erfindungsgemäßer Deckendrallauslaß besteht gemäß Figur 1 aus einem etwa quadratischen Gehäuse 1. Dieses Gehäuse 1 besitzt eine Ausblasplatte 2 sowie einen darauf aufgesetzten, aus Seitenwänden 3 bestehenden Rahmen 4 (siehe Figur 2 und 3).A ceiling swirl outlet according to the invention consists, according to FIG. 1, of an approximately square housing 1. This housing 1 has a blow-out plate 2 and a frame 4 made of side walls 3 placed thereon (see FIGS. 2 and 3).

Die Ausblasplatte 2 ist mit schlitzförmigen Auslaßöffnungen 5 durchsetzt, deren geometrische Figur im Rahmen der Erfindung ohne Bedeutung ist. Als Ausführungsbeispiel ist in Figur 1 gezeigt, daß vier Ausblasfelder von zwei entsprechenden Diagonalen 6 und 7 gebildet sind, welche in Betrieb des Deckendrallauslasses auch vier Ausblasströme ausformen.The blow-out plate 2 is interspersed with slot-shaped outlet openings 5, the geometrical figure of which is of no significance in the context of the invention. As an exemplary embodiment, it is shown in FIG. 1 that four blow-out fields are formed by two corresponding diagonals 6 and 7 which, when the ceiling swirl outlet is in operation, also form four blow-out streams.

Die Seitenwände 3 besitzen auch Seitenschlitze 8, durch welche ebenfalls Luftströme gebildet werden.The side walls 3 also have side slots 8, through which air currents are also formed.

Aus Figur 3 ist ersichtlich, daß jeder Auslaßöffnung 5 eine Luftstrahlleitlamelle 10 zugeordnet ist. Jede Luftstrahlleitlamelle 10 sitzt auf einer Drehachse 11, welche sich zwischen zwei scheibenförmigen Aufhängungen 12 befindet (Figur 4). Im vorliegenden Ausführungsbeispiel besteht jede Luftstrahlleitlamelle 10 aus einem Kunststoffhohlprofil und besitzt im Inneren einen durch zwei Stege 13 und 14 gebildeten Kanal 15, in dem die Drehachse 11 ruht. Hierdurch kann die Laufstrahlleitlamelle 10 um die Drehachse 11 gedreht werden und Positionen einnehmen, wie sie in Figur 4 strichpunktiert dargestellt sind. Je nachdem kann so ein Leiten des jeweiligen aus einer bestimmten Auslaßöffnung 5 austretenden Luftstrahles erfolgen.From Figure 3 it can be seen that each outlet opening 5 is assigned an air jet guide lamella 10. Each air jet guide lamella 10 sits on an axis of rotation 11, which is located between two disc-shaped suspensions 12 (FIG. 4). In the present exemplary embodiment, each air jet guide lamella 10 consists of a hollow plastic profile and has in the interior a channel 15 formed by two webs 13 and 14, in which the axis of rotation 11 rests. As a result, the running beam guide lamella 10 can be rotated about the axis of rotation 11 and assume positions as shown in broken lines in FIG. Depending on this, the respective air jet emerging from a specific outlet opening 5 can be directed.

In Figur 3 ist ferner ersichtlich, daß einer Auslaßöffnung 5 zugeordnete Luftstrahlleitlamelle 10 aus mehreren Teilen bestehen kann, welche separat wiederum um die Drehachse 11 drehbar sind. Im gezeigten Ausführungsbeispiel besteht jede Luftstrahlleitlamelle 10 aus einem Hauptteil 16, an dem beidseits nach jeweils einer Aufhängung 12 ein geometrisch anders geformtes Seitenteil 17 anschließt, das wiederum von einer Aufhängung 12 begrenzt ist. Letztgenannte Aufhängung wird dann noch von der Drehachse 11 durchbohrt. Auf diese Weise ist eine absolut individuelle Luftstrahlleitung gewährleistet.In FIG. 3 it can also be seen that an air jet guide lamella 10 assigned to an outlet opening 5 can consist of several parts, which in turn can be rotated separately about the axis of rotation 11. In the exemplary embodiment shown, each air jet guide lamella 10 consists of a main part 16, which is adjoined on both sides by a suspension part 12 with a geometrically differently shaped side part 17, which in turn is delimited by a suspension 12. The latter suspension is then pierced by the axis of rotation 11. In this way, an absolutely individual air jet line is guaranteed.

Die scheibenförmigen Aufhängungen 12 bestehen im übrigen der Einfachheit halber aus einer im wesentlichen rechteckigen Platte, welche durch eine schwalbenschwanzförmige Anformung 18 die Ausblasplatte 2 untergreift. Auf diese Weise ist das Einsetzen der Aufhängung 12 in die Auslaßöffnung 5 erleichtert, da die Aufhängung 12 nur mit ihrer Längsachse etwa parallel zur Achse der Auslaßöffnung 5 in diese eingeführt und dann um etwa 90° gedreht zu werden braucht.For the sake of simplicity, the disc-shaped suspensions 12 consist of an essentially rectangular plate which engages under the blow-out plate 2 by means of a dovetail-shaped projection 18. In this way, the insertion of the suspension 12 into the outlet opening 5 is facilitated, since the suspension 12 only needs to be inserted with its longitudinal axis approximately parallel to the axis of the outlet opening 5 and then have to be rotated through approximately 90 °.

Die Seitenschlitze 8 sind auch mit entsprechenden Luftstrahlleitlamellen 10a besetzt. Auch diese Luftstrahlleitlamellen 10 sind nach dem vorliegenden Ausführungsbeispiel mehrteilig ausgebildet und an einer zwischen entsprechenden Aufhängungen 12a verlaufenden Drehachse 11a gehalten.The side slots 8 are also populated with corresponding air jet guide blades 10a. According to the present exemplary embodiment, these air jet guide fins 10 are also formed in several parts and are held on an axis of rotation 11a extending between corresponding suspensions 12a.
