Description

Die Erfindung betrifft einen Drallauslaß zum Anschließen an einen Anschlußstutzen einer Luftleitung mit einer Drallscheibe, welche Schlitze mit schräg­gestellten Lamellen od. dgl. Öffnungen aufweist.The invention relates to a swirl outlet for connection to a connecting piece of an air line with a swirl disk which has slots with inclined slats or the like. Openings.

Ein derartiger Drallauslaß insbesondere als Decken­drallauslaß wird unter dem Typ DDB in dem Katalog der Anmelderin geführt. Dieser Deckenauslaß ist ein Drall­auslaß mit hoher Induktionswirkung. Er kann decken­bündig oder frei hängend eingebaut werden. In die Drallscheibe dieses Auslasses sind Schlitze eingeformt, wobei diese Einformung U-förmig geschieht.Such a swirl outlet, in particular as a ceiling swirl outlet, is listed under type DDB in the applicant's catalog. This ceiling outlet is a swirl outlet with a high induction effect. It can be installed flush with the ceiling or freely suspended. Slits are formed in the swirl disk of this outlet, this shaping taking place in a U-shape.

Beim Stanzen wird der umschnittene Steg nach innen gedrückt und bleibt als schräge Lamelle stehen. Durch diese Anordnung werden viele Teilstrahlen erreicht, welche eine optimale Drallwirkung haben. Hierdurch kommt es zu einer sehr guten Luftdurchmischung, wobei die einströmende Zuluft sowohl im Kühl- wie auch im Heizfalle sehr schnell mit der Raumluft vermischt wird. Hierdurch erfolgt ein schnelles Abbauen der Temperatur­unterschiede, wobei es beim Einbringen von Kühlluft nicht zu Zugerscheinungen kommt. Im Heizfall dringt die einströmende Warmluft sehr schnell in den Aufenthalts­bereich und baut hier die Temperaturunterschiede ab. Allerdings stößt dieser Drallauslaß in sehr hohen Räumen an Grenzen.When punching, the cut web is pressed inwards and remains as an oblique lamella. With this arrangement, many partial beams are achieved which have an optimal swirl effect. This results in very good air mixing, with the incoming air being mixed very quickly with the room air both in the cooling and in the heating case. As a result, the temperature differences are rapidly reduced, and there are no drafts when cooling air is introduced. In the case of heating, the inflowing warm air penetrates very quickly into the lounge area and reduces the temperature differences here. However, this swirl outlet reaches its limits in very high rooms.

Die Erfinder haben sich zum Ziel gesetzt, einen Drall­auslaß der oben genannten Art zu verbessern, indem sie ihn auch für hohe Räume anwendbar ausgestalten.The inventors have set themselves the goal of improving a swirl outlet of the type mentioned above by making it usable even for high rooms.

Zur Lösung dieser Aufgabe führt, daß die Drallscheibe etwa mittig zumindest eine Öffnung aufweist, welcher ein absperrbares Auslaßteil zugeordnet ist.To achieve this object, the swirl disk has at least approximately one opening in the middle, which is assigned a lockable outlet part.

Hierdurch wird ein aktivierbarer Wurfauslaß herge­stellt, welcher nur bei Gebrauch geöffnet wird, d. h. wenn eine schnelle Durchmischung der Luft auch im tieferen Bereich von Räumen erfolgen soll.This produces an activatable throwing outlet, which is only opened when in use, i.e. H. when a quick mixing of the air should also take place in the deeper area of rooms.

Bevorzugt ist nur eine mittige Öffnung in der Drallscheibe ausgestanzt, wobei das Auslaßteil zum Inneren des Drallauslasses hin die Öffnung überdeckt.Preferably, only a central opening is punched out in the swirl disk, the outlet part covering the opening toward the inside of the swirl outlet.

Wie das Auslaßteil selbst ausgestaltet ist, soll von zweitrangiger Bedeutung sein. Bevorzugt ist es schlitz­schieberartig ausgebildet. Beispielsweise kann es aus zwei oder mehreren Scheiben bestehen, welche Öffnungen aufweisen, die in Übereinstimmung gebracht werden können. Hierzu sind diese Scheiben um eine gemeinsame Achse relativ zueinander drehbar. In der Regel wird die eine Scheibe feststehend und die andere drehbar ausge­bildet sein.How the outlet part itself is designed should be of secondary importance. It is preferably designed like a slider. For example, it can consist of two or more disks that have openings that can be brought into alignment. For this purpose, these disks can be rotated relative to one another about a common axis. As a rule, one disc will be fixed and the other will be rotatable.

Wie das Drehen der Scheiben erfolgt, ist ebenfalls von untergeordneter Bedeutung. Es kann manuell erfolgen oder über ein entsprechendes Stellelement. Der Antrieb kann motorisch, elektrisch oder pneumatisch sein.How the disks are turned is also of minor importance. It can be done manually or using an appropriate control element. The drive can be motor, electrical or pneumatic.

Bevorzugt ist mit der drehenden Scheibe ein Hebelgestänge verbunden, welches dann wiederum von dem Stellelement oder manuell betätigbar ist. Das Stell­element besitzt eine Drehwelle, welche mit einem Hebel verbunden ist, der wiederum über eine Schubstange die Scheibe angreift.A lever linkage is preferably connected to the rotating disk, which in turn can then be actuated by the actuating element or manually. The control element has a rotary shaft, which is connected to a lever, which in turn engages the disc via a push rod.

Bei hohen Temperaturunterschieden im Heizfalle und zugleich bei einem Einbau in großer Höhe, wird der Auslaßteil geöffnet, so daß die entsprechende Warmluft in der Mitte konzentriert austreten kann und relativ weit geworfen wird. Sie wird sofort in die Aufenthalts­zone geführt. Auch Kühlluft kann über die erfindungs­gemäße Vorrichtung sehr gut reguliert werden. In der vorliegenden Erfindung wird somit ein bekannter Drall­auslaß mit einem Weitwurfauslaß kombiniert.With high temperature differences in the heating case and at the same time when installing at a high altitude, the outlet part is opened so that the corresponding warm air can escape in the center and is thrown relatively far. It is immediately taken to the lounge area. Cooling air can also be regulated very well via the device according to the invention. In the present invention, a known swirl outlet is thus combined with a long throw outlet.

Die Vorteile der Drallwirkung liegen eindeutig bei den eng gestanzten Einzelschlitzen. Mit dem verstellbaren Auslaßteil kann beispielsweise die Zuluftmenge im gewünschten Maße reduziert und jede gewünschte Eindringtiefe festgelegt werden. Durch die düsenartige Anströmung wird der gesamte Auslaß optimal beauf­schlagt. Ferner ist mit diesem Auslaß ein sehr gutes architektonisches Aussehen zu erreichen. Der Auslaß paßt in heutige Decken und Bauten großartig hinein.The advantages of the swirl effect are clearly the narrowly punched individual slots. With the adjustable outlet part, for example, the supply air quantity can be reduced to the desired extent and any desired penetration depth can be defined. The entire outlet is optimally acted upon by the nozzle-like inflow. Furthermore, a very good architectural appearance can be achieved with this outlet. The outlet fits great into today's ceilings and buildings.

Weitere Vorteile, Merkmale und Einzelheiten der Er­findung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung; diese zeigt in

  • Fig. 1 einen Querschnitt durch einen erfindungs­gemäßen Drallauslaß;
  • Fig. 2 eine teilweise gebrochen dargestellte Drauf­sicht auf den erfindungsgemäßen Drallauslaß gemäß Figur 1 mit zylindrischen Anschluß­stutzen.
Further advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawing; this shows in
  • Figure 1 shows a cross section through a swirl outlet according to the invention.
  • Fig. 2 is a partially broken plan view of the swirl outlet according to the invention according to Figure 1 with a cylindrical connecting piece.

Gemäß Figur 1 ist ein erfindungsgemäßer Drallauslaß 1 über entsprechende Befestigungselemente (Schrauben) 2 mit einem zylindrischen Anschlußstutzen 3 einer Luft­leitung verbunden.According to FIG. 1, a swirl outlet 1 according to the invention is connected via appropriate fastening elements (screws) 2 to a cylindrical connecting piece 3 of an air line.

Der Drallauslaß 1 besitzt eine zylindrische Seitenwand 4 sowie eine Drallscheibe 5. In die Drallscheibe 5 sind mehrere Reihen von Schlitzen 6 eingestanzt. Der einge­formte Bereich jedes Schlitzes 6 bleibt dabei als die den Drall erzeugende Lamelle 7 stehen. Durch diese relativ kleinen Stanzungen werden viele Teilstrahlen erreicht, welche eine optimale Drallwirkung auf den auszubringenden Luftstrom haben und eine sehr gute Luftdurchmischung bewirken. Dadurch wird die einströmende Zuluft, ob im Kühlfall oder im Heizfall, sehr schnell mit der Raumluft vermischt und die Temperaturunterschiede sehr schnell abgebaut.The swirl outlet 1 has a cylindrical side wall 4 and a swirl disk 5. A number of rows of slots 6 are punched into the swirl disk 5. The molded area of each slot 6 remains as the lamella 7 which produces the swirl. Through these relatively small punchings, many partial jets are achieved, which have an optimal swirl effect on the air flow to be discharged and cause very good air mixing. As a result, the incoming air, whether for cooling or heating, is very quickly mixed with the room air and the temperature differences are reduced very quickly.

Die im Kühlfalle möglichen Zugerscheinungen werden ver­mieden, während im Heizfalle die einströmende Warmluft in den Aufenthaltsbereich durch die sehr schnell abgebauten Temperaturunterschiede rasch eindringt.The drafts that are possible in the cold case are avoided, while in the heating case the inflowing warm air quickly penetrates into the lounge area due to the very quickly reduced temperature differences.

Dieser Drallscheibe 5 ist etwa mittig eine runde Öffnung 8 eingestanzt, welche mit einem absperrbaren Auslaßteil 9 überdeckt ist. Dieses Auslaßteil 9 ähnelt einem Schlitzschieber und besteht aus zwei oder mehr aufeinanderliegenden Scheiben mit meist radialen, schlitzförmigen Öffnungen. In Figur 2 ist nur die oberste Scheibe 10 mit entsprechenden Öffnungen 11 aufgezeigt.This swirl disk 5 is punched approximately in the middle of a round opening 8, which is covered with a lockable outlet part 9. This outlet part 9 resembles a slot slide valve and consists of two or more disks lying one on top of the other with mostly radial, slot-shaped openings. In Figure 2, only the top disc 10 is shown with corresponding openings 11.

Im vorliegenden Ausführungsbeispiel ist die Scheibe 10 gegenüber den darunter befindlichen Scheiben des Auslaßteiles 9 um die Achse 12 drehbar. Selbstverständ­lich könnte auch eine andere Scheibe des Auslaßteiles 9 gegenüber beispielsweise der oberen Scheibe 10 drehbar sein. Vom Erfindungsgedanken werden alle derartigen Variationen erfaßt. Durch die Drehbarkeit der Scheibe 10 wird die Position der Öffnungen 11 im Verhältnis zu den Öffnungen der darunterliegenden Scheiben verändert, so daß die Gesamtauslaßweite und damit der austretende Luftstrom geregelt werden kann. Bei hohen Temperatur­unterschieden im Heizfalle und zugleich bei einem Einbau in relativ großer Raumhöhe wird die Öffnung 11 in weitestgehende Übereinstimmung mit der darunter­liegenden Öffnung gebracht, so daß die Warmluft in der Mitte konzentriert austritt. Sie wird sofort in die Aufenthaltszone geführt. Ebenso kann auch die senkrecht ausströmende Zuluftmenge sehr gut reguliert werden.In the present exemplary embodiment, the disk 10 can be rotated about the axis 12 relative to the disks of the outlet part 9 located underneath. Of course, another disk of the outlet part 9 could also be rotatable relative to, for example, the upper disk 10. All such variations are covered by the inventive concept. Due to the rotatability of the disc 10, the position of the openings 11 is changed in relation to the openings of the underlying discs, so that the total outlet width and thus the emerging air flow can be regulated. At high temperature differences in the heating case and at the same time when installed in a relatively large room height, the opening 11 is brought into broad agreement with the opening below, so that the warm air exits concentrated in the middle. It is immediately taken to the lounge area. Likewise, the supply air volume flowing out vertically can be regulated very well.

Das Drehen der Scheibe 10 um die Achse 12 erfolgt über ein Stellelement 13. Über dieses Stellelement 13 kann die Scheibe 10 motorisch, elektrisch oder pneumatisch um die Achse 12 gedreht werden, es ist jedoch auch daran gedacht, eine manuelle Verdrehbarkeit vorzusehen.The disk 10 is rotated about the axis 12 by means of an actuating element 13. The disk 10 can be rotated about the axis 12 by motor, electrical or pneumatic means via this actuating element 13, however, it is also contemplated to provide for manual rotation.

Im vorliegenden Ausführungsbeispiel ist das Stell­element 13 auf einem Winkel 14 festgelegt. Es greift mit einer Drehwelle 15 in das Innere I des Drallauslasses 1 ein. Mit dieser Drehwelle 15 ist ein Hebel 16 verbunden, der andernends eine gelenkige Ver­bindung mit einer Schubstange 17 besitzt. Diese Schubstange 17 weist wiederum andernends eine gelenkige Verbindung mit einem Befestigungswinkel 18 auf, welcher mit der Scheibe 10 verbunden ist.In the present exemplary embodiment, the actuating element 13 is fixed at an angle 14. It engages with a rotating shaft 15 in the interior I of the swirl outlet 1. With this rotary shaft 15, a lever 16 is connected, which at the other end has an articulated connection with a push rod 17. This push rod 17 in turn has an articulated connection with a mounting bracket 18 which is connected to the disc 10.

Wird die Drehwelle 15 um ihre Achse 19 gedreht, so erfolgt ein Schwenken des Hebels 16, wobei die Schubstange 17 in etwa lineare Bewegung versetzt wird. Diese Bewegung überträgt die Schubstange 17 über den Befestigungswinkel 18 auf die Scheibe 10, wobei hier die Umsetzung in eine Drehbewegung um die Achse 12 erfolgt.If the rotary shaft 15 is rotated about its axis 19, the lever 16 is pivoted, the push rod 17 being set in approximately linear movement. This movement transmits the push rod 17 to the disk 10 via the fastening bracket 18, the conversion into a rotary movement about the axis 12 taking place here.
