Description

Die Erfindung betrifft einen Luftauslass mit Leitelementen, die in einer luftdurchlässigen Platte mit gegenüber diesen höherem Strömungswiderstandsbeiwert angeordnet sind und aus dem Luftauslass austretende Luft in divergierende Richtungen lenken, wobei mindestens ein Leitelement um eine zu der Platte senkrechte Achse drehbar ist.The invention relates to an air outlet with baffle elements that are in an air-permeable Plate with this higher flow resistance coefficient are arranged and made direct air escaping from the air outlet in divergent directions, at least one Guide element is rotatable about an axis perpendicular to the plate.

Stand der TechnikState of the art

Ein gattungsgemäßer Luftauslass ist beispielsweise in der DE 199 21 404 C1 beschrieben. Dieser vorgeschlagene Luftauslass weist in einem Lochblech eine Kombination verschiedener Leitelemente, nämlich sowohl Drallauslässe als auch mindestens einen richtungsverstellbaren Strahlauslass in Form einer "Weitwurfdüse" auf.A generic air outlet is described for example in DE 199 21 404 C1. This proposed air outlet has a combination of different in a perforated plate Guide elements, namely both swirl outlets and at least one directionally adjustable Jet outlet in the form of a "long throw nozzle".

Einen weiteren gattungsgemäßen Luftauslass zeigt die DE 9 116 077 U1. Um Teilströme eines Luftvolumenstroms in unterschiedliche Richtungen in einen Raum einblasen zu können, werden hier mehrere kreisförmige Luftleitelemente in einer Trägerplatte drehbar angeordnet. Im Ausführungsbeispiel sind die Leitelemente mit jalousieartig angeordneten Luftleitblechen versehen.Another generic air outlet is shown in DE 9 116 077 U1. To a partial stream To be able to blow air volume flow into a room in different directions, several circular air guide elements are rotatably arranged in a carrier plate. In the exemplary embodiment, the guide elements are provided with air baffle plates arranged in the manner of blinds Mistake.

Allgemein bekannt sind Luftauslässe mit starren, verstellbaren oder im Betriebsfall selbsttätig öffnenden Lamellen zur Leitung der ausströmenden Luft. Derartige Luftauslässe kommen insbesondere an raumseitigen Öffnungen in der Klimatechnik in einer Vielzahl verschiedener Ausführungsformen für die unterschiedlichen Anwendungsfälle zum Einsatz.Air outlets with rigid, adjustable or automatic in operation are generally known opening slats for directing the escaping air. Such air outlets come especially at room-side openings in air conditioning technology in a variety of different ways Embodiments for the different applications are used.

Die bekannten Lamellenauslässe werden beispielsweise in der Gebäude-Klimatechnik bündig abschließend in Raumwände installiert. In Form von Kreuzlamellen, die eine unabhängige Verstellung in zwei aufeinander senkrechten Raumrichtungen ermöglichen, werden gattungsgemäße Luftauslässe aber auch zur Belüftung von Fahrzeug-Innenräumen eingesetzt.The well-known lamella outlets are flush, for example, in building air conditioning technology finally installed in room walls. In the form of cross blades, which is an independent Allow adjustment in two mutually perpendicular spatial directions are generic Air outlets also used for ventilation of vehicle interiors.

Wird der angeschlossene Luftkanal der Klimaanlage mit Druck beaufschlagt, so dringt die konditionierte - geheizte oder gekühlte - Luft durch den Luftauslass in den Raum und wird dabei durch die Lamellen in die eingestellte Richtung geleitet. Die gekühlten Luftstrahlen neigen dazu, mit erhöhten Luftgeschwindigkeiten in den Aufenthaltsbereich abzufallen, was von den Raumnutzern als störende "Zugluft" empfunden wird. Insbesondere das Komfortempfinden von Raumnutzern, die sich aufgrund beengter räumlicher Verhältnisse im Bereich des Kaltlufabfalles aufhalten, wird empfindlich gestört. Daher ist die Freiheit der Nutzung eines Raumes wesentlich eingeschränkt.If the connected air duct of the air conditioning system is pressurized, it penetrates conditioned - heated or cooled - air through the air outlet into the room and is guided through the slats in the set direction. The cooled air jets tend to drop into the lounge area with increased air speeds, what is perceived by the room users as annoying "drafts". In particular, the feeling of comfort of room users who are due to cramped spatial conditions in the area stopping the cold air waste is disturbed. Hence freedom of use of a room significantly restricted.

Die Leitelemente - die Lamellen des bekannten Luftauslasses - verdecken physisch die Öffnung der angeschlossenen klimatechnischen Anlage. Darüber hinaus sind Luftauslässe aber häufig auch das einzige für den Nutzer optisch wahrnehmbare Bauteil einer daran angeschlossenen klimatechnischen Anlage, insbesondere wenn die angeschlossenen Luftkanäle in Raumwände oder -decken integriert sind. Bei der Konzeption von Luftauslässen sind daher neben rein funktionalen auch gestalterische Überlegungen anzustellen. Die durch die relativ großen Öffnungen auffällig kontrastreichen und durch die geraden Linien streng wirkenden bekannten Lamellenauslässe sind gerade an einfarbigen Wandflächen nur schwer zu verbergen und prägen auf diese Weise häufig in unerwünschter Weise wesentlich den Gesamteindruck eines Raumes.The guide elements - the slats of the well-known air outlet - physically cover the opening the connected air conditioning system. In addition, there are air outlets often also the only component of an attached component that is visually perceptible to the user Air conditioning system, especially if the connected air ducts in Room walls or ceilings are integrated. So when designing air outlets in addition to purely functional considerations. The through the relative large openings strikingly high-contrast and with the straight lines appearing strict Known lamella outlets are difficult to hide, especially on single-colored wall surfaces and often have an undesirable impact on the overall impression of a room.

Aufgabetask

Aufgabe der Erfindung ist es, einen Luftauslass vorzuschlagen, der gegenüber den bekannten Vorrichtungen einerseits eine zugfreie Durchströmung des klimatisierten Raumes und andererseits eine gefälligere Gestaltung ermöglicht.The object of the invention is to propose an air outlet that compared to the known Devices on the one hand a draft-free flow through the air-conditioned room and on the other hand allows a more pleasing design.

Lösungsolution

Ausgehend von der eingangs beschriebenen Vorrichtung wird diese Aufgabe nach der Erfindung dadurch gelöst, dass mindestens ein Leitelement eine Mehrzahl von Düsen aufweist.Starting from the device described in the introduction, this object is achieved according to the invention solved in that at least one guide element has a plurality of nozzles.

Der durch den Luftauslass austretende Luftstrom wird so aufgefächert und stellt damit keine über temperaturbedingte Konvektion hinaus gehende Ursache für störende Luftströmungen im Raum mehr dar. Die Auffächerung des austretenden Luftstroms in verschiedene divergierende Richtungen geschieht sehr effektiv durch den Einsatz mehrerer kleinerer Leitelemente, die aufgrund der geringeren Abmessungen wiederum optisch leichter zu verbergen oder variabler in vorhandene Strukturen zu integrieren sind. The airflow exiting through the air outlet is thus fanned out and thus does not constitute any cause of disturbing air currents in the air beyond temperature-related convection Space represents more. The fanning out of the exiting air flow into different diverging Directions happens very effectively through the use of several smaller guide elements that due to the smaller dimensions, it is easier to hide or more variable are to be integrated into existing structures.

Besonders vorteilhafter Weise beträgt der Strömungswiderstandsbeiwert der luftdurchlässigen Platte das fünf- bis zwanzigfache des Strömungswiderstandsbeiwert der Leitelemente. Die Geschwindigkeit der aus den Leitelementen austretenden Luft ist dann - bei üblichen Druckverhältnissen - etwa drei- bis fünfmal höher als die Austrittsgeschwindigkeit aus der luftdurchlässigen Platte. Auf diese Weise sind die Luftstrahlen aus den Leitelementen in der Lage, den restlichen Luftvolumenstrom zu lenken und zu führen.The flow resistance coefficient of the air-permeable is particularly advantageously Plate five to twenty times the drag coefficient of the guide elements. The The speed of the air escaping from the guide elements is then - under normal pressure conditions - About three to five times higher than the exit speed from the air-permeable Plate. In this way, the air jets from the guide elements are able to to direct and guide the remaining air volume flow.

Der erfindungsgemäße Luftauslass lässt sich an unterschiedliche räumliche Verhältnisse und Einbausituationen besonders gut anpassen, wenn die Richtungen der an den einzelnen Leitelementen austretenden Luftströme unabhängig einstellbar sind. Die Leiteinrichtungen werden in einen flächigen Luftauslass optisch gut integriert, wenn sie in der Fläche der Platte liegen und die Verstellung durch Drehung um eine zu der Platte senkrechte Achse erfolgt.The air outlet according to the invention can be adapted to different spatial conditions and Adapt the installation situation particularly well if the directions on the individual guide elements escaping air flows are independently adjustable. The guidance systems will optically well integrated into a flat air outlet if it is in the surface of the plate lie and the adjustment is carried out by rotation about an axis perpendicular to the plate.

Eine Mehrzahl von Düsen, insbesondere mit kreisförmigem Querschnitt, ermöglicht eine im Vergleich zu den bekannten Lamellenauslässen gefälligere Gestaltung des Luftauslasses. Durch eine Neigung der Düsenrichtungen gegenüber einer auf dem Leitelement senkrechten Richtung und durch eine Variation der Düsenrichtungen innerhalb eines Leitelementes kann der Effekt der Strahlauffächerung noch deutlich gesteigert werden. Leitelemente mit besonders stark geneigten Düsenrichtungen kommen bevorzugt an den Rändern des erfindungsgemäßen Luftauslasses zum Einsatz. Besonders einfach können derartige Leitelemente in Scheibenform und mit durchgehenden Strahlkanälen gefertigt werden, wobei die Strahlkanäle als Düsen fungieren.A plurality of nozzles, in particular with a circular cross section, enables an in Compared to the known lamella outlets, the air outlet is more pleasing. By an inclination of the nozzle directions in relation to one perpendicular to the guide element Direction and by varying the nozzle directions within a guide element the effect of beam spreading can be increased significantly. Guiding elements with special strongly inclined nozzle directions come preferably at the edges of the invention Air outlet for use. Such guiding elements in disk form can be particularly simple and be produced with continuous beam channels, the beam channels being Nozzles act.

Die luftdurchlässige Platte des erfindungsgemäßen Luftauslasses wird bevorzugt als Lochblech ausgebildet. Während die Auswahl eines sichtbaren Lochbleches durch die gewünschte Austrittsgeschwindigkeit und durch ästhetische Überlegungen eingeschränkt ist, kann der Strömungswiderstand der Platte durch ein zweites, innenliegendes Lochblech einfach in gewünschter Weise eingestellt werden. Eine solche zweischalige Platte weist gegenüber der einschaligen Ausführung darüber hinaus eine deutlich erhöhte Steifigkeit auf und ermöglicht den Einsatz des erfindungsgemäßen Luftauslasses in einer großflächigen Ausführung ohne weitere stützende Elemente. Alternativ kann der Strömungswiderstand der Platte des Luftauslasses auch durch ein auf der Platte liegendes Vlies auf einen gewünschten Wert eingestellt werden.The air-permeable plate of the air outlet according to the invention is preferably used as a perforated plate educated. While choosing a visible perforated sheet by the desired one Exit speed and is limited by aesthetic considerations, the Flow resistance of the plate through a second, internal perforated plate simply in the desired Way to be set. Such a double-skin plate points towards the single-shell design also has a significantly increased rigidity and enables the use of the air outlet according to the invention in a large area without other supporting elements. Alternatively, the flow resistance of the plate of the air outlet also set to a desired value by a fleece lying on the plate become.

Bevorzugt ist insbesondere eine Ausführung des erfindungsgemäßen Luftauslasses, auf dessen Platte Leitelemente in mehreren Reihen angeordnet sind. So wird eine besonders gleichmäßige Strömung durch den Luftauslass realisiert.Particularly preferred is an embodiment of the air outlet according to the invention, on the Plate guiding elements are arranged in several rows. So it becomes a particularly even one Flow through the air outlet realized.

In dem erfindungsgemäßen Luftauslass wird der austretende Luftstrom in mehrere divergierende Hauptluftströme mit höherem Strahlimpuls und dünnen Einzelstrahlen und einen diffus austretenden Nebenluftstrom mit geringerem Impuls aufgeteilt, dem wiederum die Hauptluftströme ihre Richtungen aufprägen können. Dieses erfindungsgemäße Verfahren bewirkt eine wirksame Auffächerung des durch den Luftauslass austretenden Luftstroms und damit gegenüber den bekannten Luftauslässen eine deutliche Verringerung der Raumluftgeschwindigkeiten im Aufenthaltsbereich. Der Raum kann auf diese Weise zugluftfrei mit vergleichsweise großen Volumenströmen durchspült werden. In the air outlet according to the invention, the exiting air flow is divided into several Main air flows with higher jet impulse and thin single jets and a diffuse one escaping secondary air flow divided with less momentum, which in turn the main air flows can impress their directions. This method according to the invention brings about a effective fanning out of the air flow exiting through the air outlet and thus opposite the known air outlets a significant reduction in indoor air speeds in the lounge area. The room can be draft free in this way with comparatively large volume flows are flushed.

Der Luftauslass 1 weist eine Platte 3 mit zwei parallel zueinander angeordneten Lochblechen 4 und 5, und zwanzig in zwei parallelen Reihen angeordnete Leitelemente 6 und rückseitig einen rechtwinklig zu den Lochblechen angeordneten, umlaufenden Einbaurahmen 7 auf. Der Verlauf des in Fig. 1 dargestellten Schnitts durch den Luftauslass 1 ist in Fig. 2 durch eine gestrichelte Linie angedeutet. Der Strömungswiderstandsbeiwert des Lochbleches 4 ist um den Faktor zwölf höher als der Strömungswiderstandsbeiwert der Leitelement 6. Die Austrittsgeschwindigkeit der Luftstrahlen aus den Leitelement 6 ist etwa dreieinhalb mal höher als die Geschwindigkeit der aus dem Lochblech 4 austretenden Luft.The air outlet 1 shown in FIGS. 1 and 2 is a cutout of one only in FIG. 1 shown curtain wall 2 of a room not shown with behind, Supply air ducts, not shown, as part of a system for Air conditioning of the room - if necessary for heating or cooling and for supplying Fresh air - built in. The air outlet 1 has a plate 3 with two arranged parallel to each other Perforated sheets 4 and 5, and twenty guide elements arranged in two parallel rows 6 and on the back a circumferential one arranged at right angles to the perforated plates Installation frame 7. The course of the section shown in FIG. 1 through the air outlet 1 is indicated in Fig. 2 by a dashed line. The drag coefficient of the Perforated plate 4 is a factor of twelve higher than the flow resistance coefficient of the guide element 6. The exit velocity of the air jets from the guide element 6 is about three and a half times higher than the speed of the air emerging from the perforated plate 4.

    Der Einbaurahmen 7 ist mit nicht dargestellten Schraubverbindungen fest an der Wand 2 verankert, die Platte 3 ist in den Einbaurahmen 7 in nicht dargestellte Befestigungselemente eingehängt. Eine Blende 8 an der Platte 3 verdeckt den Einbauspalt 9 und liegt an der Wand 2 bündig an. Der Einbauspalt 9 und der toleranzbedingte Abstand der Blende 8 von der Wand 2 sind in Fig. 1 zur Verdeutlichung der Einbausituation übertrieben dargestellt.The mounting frame 7 is firmly anchored to the wall 2 with screw connections, not shown, the plate 3 is suspended in the mounting frame 7 in fasteners, not shown. A panel 8 on the plate 3 covers the installation gap 9 and lies on the wall 2 flush. The installation gap 9 and the tolerance-related distance of the panel 8 from the wall 2 are exaggerated in Fig. 1 to illustrate the installation situation.

    Das in Fig. 3 und Fig. 4 dargestellte kreiszylinderförmige Leitelement 6 liegt fast vollständig in einer durchgehenden, ebenfalls kreiszylindrischen Öffnung 10 der Platte 3. Das Leitelement 6 ist mit einer nicht dargestellten angeformten umlaufenden Wulst in einer ebenfalls nicht dargestellten umlaufenden Nut in dieser Öffnung 10 gegen axiale Verschiebung gesichert. Es schließt bündig mit dem inneren Lochblech 4 der Platte 3 ab und ist an der sichtbaren Außenseite mit einem angeformten Kragen 11 versehen, der zum Einen den Einbauspalt 12 verdeckt und zum Andern zusätzlich die axiale Verschiebung des Leitelementes 6 in den Luftauslass 1 hinein verhindert.The circular-cylindrical guide element 6 shown in FIGS. 3 and 4 lies almost completely in a continuous, also circular cylindrical opening 10 of the plate 3. The guide element 6 is also with an integrally formed circumferential bead, not shown not shown circumferential groove secured in this opening 10 against axial displacement. It is flush with the inner perforated plate 4 of the plate 3 and is visible Provided on the outside with a molded collar 11, which on the one hand the installation gap 12 concealed and in addition the axial displacement of the guide element 6 in the Air outlet 1 prevented.

    Das Leitelement 6 weist sieben durchgehende, parallel verlaufende, kreiszylindrische Düsen 13 auf, die um einen Winkel 14 gegenüber einer zur Oberfläche des Leitelementes 6 senkrechten Achse 15 geneigt sind. Auch hier sind der Einbauspalt 12 und der toleranzbedingte Abstand des Kragens 11 von der Platte 3 zur Verdeutlichung der Einbausituation übertrieben dargestellt.The guide element 6 has seven continuous, parallel, circular cylindrical nozzles 13, which is at an angle 14 with respect to the surface of the guide element 6 vertical axis 15 are inclined. Also here are the installation gap 12 and tolerance-related distance of the collar 11 from the plate 3 to illustrate the Installation situation exaggerated.

    Das Leitelement 6 ist in der Platte 3 um 360° drehbar und wird bei Einrichtung des erfindungsgemäßen Luftauslasses 1 manuell auf die gewünschte Richtung eingestellt. Ebenso kann der Luftauslass 1 durch den Raumnutzer jederzeit mittels Verdrehen einzelner Leitelemente 6 an geänderte Bedürfnisse angepasst werden.The guide element 6 can be rotated through 360 ° in the plate 3 and becomes when the device according to the invention is set up Manually set air outlet 1 in the desired direction.
