Description

Die Erfindung betrifft einen Drallauslass, zur Belüftung von Räumen, mit einem Gehäuse, das einen Zuluftstutzen und einen eine Auslassöffnung bildenden, insbesondere viereckigen, Frontdurchlass aufweist, wobei in dem Frontdurchlass mehrere Durchlassöffnungen vorgesehen sind und der Frontdurchlass anströmseitig zu jeder Durchlassöffnung ein der jeweiligen Durchlassöffnung zugeordnetes als Drallschaufel ausgebildetes Luftleitelement umfasst, wobei jedes Luftleitelement in Strömungsrichtung gesehen gekrümmt ausgebildet ist.The invention relates to a swirl diffuser, for ventilating rooms, having a housing which has an inlet air nozzle and an outlet opening, in particular quadrangular, front passage, wherein in the front passage a plurality of passage openings are provided and the front passage upstream of each passage opening one of the respective passage opening assigned comprises air guide element designed as a swirl blade, wherein each air guide element is formed curved in the flow direction.

Drallauslässe sind üblicherweise in oder unterhalb von Raumdecken angeordnet und werden mittels des Zuluftstutzens an einem Belüftungssystem angeschlossen. Aus der EP 0 505 739 A1 ist eine Luftdüse bekannt, die in Strömungsrichtung gesehen gekrümmte Luftleitelemente aufweist. Die DE 101 39 542 A1 betrifft eine Vorrichtung zur Umwandlung einer Drallströmung an Luftauslässen und die EP 1 099 914 A1 einen Luftauslass. Bei Drallauslässen wird durch die radiale Anordnung der Drallschaufeln die Luft unter Drall in den zu belüftenden Raum eingebracht. Hierbei wird Raumluft induziert. Als Nachteil erweist sich, dass vereinzelt keine hinreichende Drallwirkung und damit nicht die gewünschte Induktion erzielt werden kann.Twist outlets are usually arranged in or below ceilings and are connected by means of Zuluftstutzens to a ventilation system. From the EP 0 505 739 A1 an air nozzle is known, which has seen in the flow direction curved air guide elements. The DE 101 39 542 A1 relates to a device for converting a swirl flow to air outlets and the EP 1 099 914 A1 an air outlet. In twist outlets, the air is introduced into the space to be ventilated by the radial arrangement of the swirl blades. This room air is induced. The disadvantage is that isolated no sufficient swirl effect and thus not the desired induction can be achieved.

Aufgabe der Erfindung ist es, die vorgenannten Nachteile zu vermeiden und einen Drallauslass anzugeben, mittels dem eine größere Drallwirkung erzielt werden kann.The object of the invention is to avoid the aforementioned disadvantages and to provide a twist outlet, by means of which a greater swirl effect can be achieved.

Diese Aufgabe wird durch die Merkmale das Patentanspruch 1 gelöst. Die Mitte des Frontdurchlasses kann auch als Mittelbereich ausgebildet sein.This object is solved by the features of claim 1. The center of the front passage may also be formed as a central region.

Die Luftleitelemente sind in Strömungsrichtung gesehen gekrümmt ausgebildet, so dass damit der Verlauf eines Luftleitelementes von seiner anströmseitigen Kante zu seiner abströmseitigen, d. h. raumseitigen, Kante zunehmend horizontaler wird.The air guide elements are curved as seen in the flow direction, so that thus the course of an air guide from its upstream edge to its downstream, d. H. room side, edge becomes increasingly horizontal.

Darüber hinaus sind die Luftleitelemente in ihrer Längserstreckung gesehen gekrümmt ausgebildet. Unter der Längserstreckung der Luftleitelemente wird der Verlauf des betreffenden Luftleitelementes vom äußeren Randbereich des Frontdurchlasses zur Mitte hin und umgekehrt, verstanden. Damit erhält der Frontdurchlass in der Draufsicht ein Erscheinungsbild nach Art eines Strudels oder einer Spirale.In addition, the air guide elements are seen curved in their longitudinal extent. Under the longitudinal extent of the air guide elements, the course of the relevant air guide element from the outer edge region of the front passage to the center and vice versa, understood. Thus, the front passage in the plan view receives an appearance like a vortex or a spiral.

Da der Anstellwinkel α eines jeden Luftleitelementes entlang der Längserstreckung des Luftleitelementes unterschiedlich groß ist und von dem der Mitte abgewandten Ende zu dem der Mitte zugewandten Ende des Luftleitelementes, vorzugsweise kontinuierlich, zunimmt, weist jedes Luftleitelement vom äußeren Randbereich des Frontdurchlasses zur Mitte hin einen Verwindungsanstieg auf.Since the angle of attack α of each air guide element along the longitudinal extent of the air guide element varies in size and from the middle remote end to the center facing end of the air guide element, preferably continuously increases, each air guide from the outer edge region of the front passage toward the middle on a torsion increase ,

Durch die gekrümmte Kontur des Luftleitelementes einerseits in Strömungsrichtung gesehen und andererseits in Längserstreckung gesehen kann ein widerstandsfreierer, verlustärmerer, wirbelärmerer und turbulenzärmerer Drall erzeugt werden. Während bei bekannten Drallauslässen, bei denen jedes Luftleitelement plan ausgebildet ist und damit in einer Ebene liegt, alle Geschwindigkeitskomponenten bezogen auf dieses Luftleitelement in die gleiche Richtung weisen, fächern sich bei der erfindungsgemäßen Ausgestaltung die Geschwindigkeitskomponenten, die regelmäßig senkrecht zum Luftleitelement ausgerichtet sind, auf. Dies wirkt sich insbesondere bei den Geschwindigkeitskomponenten im Bereich des der Mitte angewandten Ende eines Luftleitelementes aus. Damit erhält der so erzeugte Drall ein flacheres Strahlbild. Gleichzeitig wird eine höhere Induktion und damit ein Geschwindigkeitsabbau schon in einem geringen Abstand bewirkt.As a result of the curved contour of the air-guiding element seen on the one hand in the flow direction and on the other hand seen in the longitudinal extent, a resistance-free, low-loss, low-turbulence and turbulence-poor swirl can be produced. While in known twist outlets, in which each air guide element is flat and thus lies in one plane, all speed components with respect to this air guide point in the same direction, fan in the embodiment of the invention, the speed components that are regularly aligned perpendicular to the air guide on. This has an effect especially on the velocity components in the region of the middle of the applied end of an air guide element. Thus, the swirl thus generated receives a flatter spray pattern. At the same time a higher induction and thus a speed reduction is effected even at a small distance.

Der Anstellwinkel α kann im Bereich des der Mitte abgewandten Endes des Luftleitelementes etwa 20° bis 28°, vorzugsweise 24°, betragen.The angle of attack α may be about 20 ° to 28 °, preferably 24 °, in the region of the end of the air guiding element facing away from the center.

Vorzugsweise kann der Anstellwinkel α im Bereich des der Mitte zugewandten Endes des Luftleitelementes etwa 30° bis 40°, vorzugsweise 36°, betragen.Preferably, the angle of attack α in the region of the center-facing end of the air guide element about 30 ° to 40 °, preferably 36 °, amount.

Dabei kann die Breite B zumindest einer Durchlassöffnung geringer als die Projektion P auf die Ebene E des dieser Durchlassöffnung zugeordneten Luftleitelements sein.In this case, the width B of at least one passage opening may be smaller than the projection P on the plane E of the air guide element associated with this passage opening.

Für ein strömungstechnisch günstiges Verhalten bietet sich an, wenn die anströmseitige Kante zumindest eines Luftleitelementes abgerundet ausgebildet ist.For a fluidically favorable behavior is advisable if the upstream edge of at least one air guide element is rounded.

Auch bietet sich an, wenn die abströmseitige Kante zumindest eines Luftleitelementes abgerundet ausgebildet ist.It also makes sense if the downstream edge of at least one air guide element is rounded.

Die Luftleitelemente können dabei einstückig mit dem Frontdurchlass ausgebildet sein. Dabei kann zwischen zwei benachbarten Durchlassöffnungen jeweils ein stegförmiger Zwischenbereich in der Ebene des Frontdurchlasses sein, an dem zumindest ein Luftleitelement angelenkt ist.The air guide elements can be formed integrally with the front passage. In this case, between two adjacent passage openings in each case a web-shaped intermediate region in the plane of the front passage, on which at least one air guide element is articulated.

Vorzugsweise ist der Frontdurchlass aus Kunststoff. In diesem Fall kann der Frontdurchlass beispielsweise mittels eines Spritzgießverfahrens hergestellt werden. Auch andere Materialien, wie Blech, sind selbstverständlich möglich.Preferably, the front passage is made of plastic. In this case, the front passage can be manufactured, for example, by means of an injection molding process. Other materials, such as sheet metal, are of course possible.

In Fig. 1 ist ein Frontdurchlass 1 eines erfindungsgemäßen Drallauslasses dargestellt. Mit der Anströmseite ist der Frontdurchlass 1 an einem nicht dargestellten Gehäuse montiert, das einen Zuluftstutzen aufweist, über den das Gehäuse an einem Klimasystem angeschlossen ist.In Fig. 1 a front passage 1 of a swirl outlet according to the invention is shown. With the inflow side of the front passage 1 is mounted on a housing, not shown, which has a Zuluftstutzen, via which the housing is connected to an air conditioning system.

Wie Fig. 1 zu entnehmen ist, weist der Frontdurchlass 1 einen Mittelbereich 2 auf. In dem Mittelbereich 2 ist eine mittige Bohrung 3 vorgesehen, durch die ein nicht dargestelltes Befestigungsmittel zur Befestigung des Frontdurchlasses 1 an dem Gehäuse einführbar ist. Nach der Montage kann der Mittelbereich 3 durch ein geeignetes Abdeckelement abgedeckt werden. Sofern auch das Abdeckelement Öffnungen aufweist, über die Luft in den Raum geführt werden soll, sind in dem Mittelbereich 2 Luftzuführöffnungen 4 vorgesehen.As Fig. 1 can be seen, the front passage 1 has a central region 2. In the central region 2, a central bore 3 is provided, through which a fastening means, not shown, for fastening the front passage 1 to the housing can be inserted. After assembly, the central region 3 can be covered by a suitable cover. If the cover element also has openings through which air is to be conducted into the room, air supply openings 4 are provided in the middle area.

Der Frontdurchlass 1 weist eine runde Außenkontur auf. Die Luftleitelemente 6 sind, wie in Fig. 1 erkennbar, in ihrer Längserstreckung gesehen, gekrümmt ausgebildet, so dass der Frontdurchlass 1 ein Aussehen nach Art einer Spirale oder eines Strudels erhält.The front passage 1 has a round outer contour. The air guide elements 6 are, as in Fig. 1 recognizable seen in its longitudinal extent, curved, so that the front passage 1 receives a look in the manner of a spiral or a vortex.

Die Fig. 2 bis 4 zeigen Schnitte durch den Gegenstand nach Fig. 1. Wie insbesondere den Detailzeichnungen "X", "Y" und "Z" zu entnehmen ist, ist jedes Luftleitelement 6 in Strömungsrichtung 7 gesehen gekrümmt ausgebildet, so dass damit der Verlauf eines Luftleitelementes 6 von seiner anströmseitigen Kante 8 zu seiner abströmseitigen, d. h. raumseitigen, Kante 9 zunehmend horizontaler wird.The Fig. 2 to 4 show cuts through the object Fig. 1 , As can be seen in particular from the detail drawings "X", "Y" and "Z", each air guide element 6 is curved as seen in the flow direction 7, so that the course of an air guide element 6 from its upstream edge 8 to its downstream, ie room-side, Edge 9 becomes increasingly horizontal.

Wie den Schnittdarstellungen der Fig. 2 bis 4 zu entnehmen ist, ist der Anstellwinkel α eines jeden Luftleitelementes 6 entlang der Längserstreckung des Luftleitelementes 6 unterschiedlich groß und nimmt von dem der Mitte abgewandten Ende zu dem dem Mittelbereich 2 zugewandten Ende des Luftleitelementes 6 zu.Like the sectional views of the Fig. 2 to 4 can be seen, the angle of attack α of each air guide element 6 along the longitudinal extent of the air guide element 6 is different in size and increases from the middle end facing away from the middle region 2 facing the end of the air guide element 6.

Der Anstellwinkel α liegt zwischen der generellen Ebene E des Frontdurchlasses 1 einerseits und einer Geraden G andererseits, wobei die Gerade G zwischen der anströmseitigen Kante 8 und der abströmseitigen Kante 9 eines Luftleitelementes 6 verläuft.The angle of attack α lies between the general plane E of the front passage 1 on the one hand and a straight line G on the other hand, the straight line G extending between the upstream edge 8 and the downstream edge 9 of an air guide element 6.

Wie insbesondere Fig. 2 zu entnehmen ist, ist die Breite B einer Durchlassöffnung 5 geringer als die Projektion P des dieser Durchlassöffnung 5 zugeordneten Luftleitelementes 6.In particular Fig. 2 2, the width B of a passage opening 5 is smaller than the projection P of the air guide element 6 assigned to this passage opening 5.

Bei dem dargestellten Ausführungsbeispiel weist der Frontdurchlass 1 einen umlaufenden Randstreifen 10 auf, der außenseitig die Durchlassöffnungen 5 und die Luftleitelemente 6 umgibt. Auf der Anströmseite des Frontdurchlasses 1 ist ein umlaufender Kragen 11 vorgesehen. Mit seinem jeweiligen dem Mittelbereich abgewandten Ende berührt jedes Luftleitelement 6 den Kragen 11.In the illustrated embodiment, the front passage 1 has a circumferential edge strip 10 which surrounds the outside of the passage openings 5 and the air guide elements 6.
