Definitions
- the invention relates to an air outlet from a cylindrical or polygonal outer housing arranged vertically with its central axis.
- the outer casing is provided with nozzles distributed over the circumference of the casing.
- An inner housing is arranged inside the outer housing.
- the casing of the inner housing consists of a perforated plate or sieve.
- a connection piece is arranged coaxially on the inner housing, which opens into a core space enclosed by the inner housing and projects over an end face of the outer housing.
- Such air outlets are generally known and enable the generation of a displacement flow with which pollutants can be removed from the area where a room is located without any significant turbulence.
- the individual air jets are introduced into the room with little turbulence and with little induction. While the perforated plate or sieve forming the jacket of the induction housing ensures an equalization of the supply air distribution over the height and the circumference of the outlet, the nozzles in the jacket of the outer housing increase the jet characteristics.
- the invention has for its object to propose an air outlet of the type described in the introduction, in which the jet direction of the nozzles can optionally be changed without the need to adjust the nozzles, so that correspondingly complex nozzle designs and adjusting devices can be dispensed with.
- the flap according to the invention on one end face of the outer housing, depending on the flap opening position, a more or less large volume flow can be introduced directly into the room via the front opening which can also be completely closed by the flap.
- the nozzles in the Sheath of the outer housing are arranged in a plane adjacent to the flap, the jet direction of the nozzles is influenced in a highly effective manner depending on the degree of opening of the flap, so that a change in the jet direction can be brought about by simply adjusting the flap.
- the distance at which the inner housing ends from the level of the flap can also influence the jet direction in the closed position of the flap. The larger this distance is selected, the less the supply air jets will fall down, for example, if they are colder than the room air.
- the supply air jets can also be deflected in a simple manner in such a way that - the further the flap is opened - the more the air jets are deflected from the horizontal to the vertical direction.
- the air outlet is arranged above a residence area, the area can be heated more quickly in the event of heating.
- the lounge area can be flushed out intensively for a short time with a vertically introduced air jet.
- a change of direction of the air jets can then again be carried out as required.
- two flaps pivotable about an axis are mounted on an end face of the outer housing, the axis dividing the outline of the outer housing into two equal-sized surfaces.
- This configuration allows the volume flow emerging directly from the air outlet to be divided into two partial flows.
- the flaps are pivoted independently of one another on the axis, so that the direction of each partial flow and the intensity of the influence of the adjacent nozzles in the casing of the housing can be varied.
- an embodiment of the invention provides that the connecting piece is connected telescopically to the inner housing and the depth of penetration into the outer housing can be varied.
- This configuration also allows the jet direction of the nozzles to be influenced, in particular when the flap is closed.
- the air outlet consists of a hexagonal outer housing 1, which is arranged vertically with its central axis. In the vicinity of an end face, two nozzles 2 are arranged on each of the six sides of the outer housing 1, the central axes of which lie in a horizontal plane.
- a cylindrical inner housing 3 which is formed from a perforated plate or sieve, is arranged concentrically to the outer housing 1.
- the outer housing 1 and the inner housing 3 define a free annular space 4, wherein a core space 5 enclosed by the inner housing 3 can be supplied with supply air via a standardized nozzle 6.
- the connector 6 projects over an end face of the outer housing 1.
- two flaps 8, which are arranged in mirror image, are pivotably mounted about an axis 7. 4 to 6 and 7 to 9 illustrate, depending on the respective position of the flaps 8, the different flow directions indicated by arrows result.
- the flaps 8 are in the closed position, so that the volume flow supplied to the air outlets from floor ducts 9 (FIG. 10) or a ceiling duct 10 (FIG. 11) is horizontal into the occupied area (FIG. 10 ) or via this (Fig. 11) is initiated.
- the volume flow loaded with pollutants is finally discharged via exhaust air ducts 11 and 12 in the ceiling or floor area of the room.

Abstract
Description
Die Erfindung betrifft einen Luftauslaß aus einem mit seiner Mittelachse vertikal angeordneten zylindrischen oder polygonalen Außengehäuse. Der Mantel des Außengehäuses ist mit über den Gehäuseumfang verteilten Düsen versehen. Innerhalb des Außengehäuses ist ein Innengehäuse angeordnet. Der Mantel des Innengehäuses besteht aus einem Lochblech oder Sieb. Zwischen dem Mantel des Innen- und des Außengehäuses befindet sich ein freier Ringraum. Koaxial am Innengehäuse ist ein Anschlußstutzen angeordnet, der in einen vom Innengehäuse umschlossenen Kernraum mündet und über eine Stirnseite des Außengehäuses vorsteht.The invention relates to an air outlet from a cylindrical or polygonal outer housing arranged vertically with its central axis. The outer casing is provided with nozzles distributed over the circumference of the casing. An inner housing is arranged inside the outer housing. The casing of the inner housing consists of a perforated plate or sieve. There is a free annular space between the jacket of the inner and outer housing. A connection piece is arranged coaxially on the inner housing, which opens into a core space enclosed by the inner housing and projects over an end face of the outer housing.
Derartige Luftauslässe sind allgemein bekannt und ermöglichen die Erzeugung einer Verdrängungsströmung, mit der sich Schadstoffe ohne eine nennenswerte Verwirbelung aus dem Aufenthaltsbereich eines Raums abführen lassen. Dazu werden die einzelnen Luftstrahlen turbulenzarm und mit einer geringen Induktion in den Raum eingeleitet. Während das den Mantel des Induktionsgehäuses bildende Lochblech oder Sieb für eine Vergleichmäßigung der Zuluftverteilung über die Höhe und den Umfang des Auslasses sorgt, bewirken die Düsen im Mantel des Außengehäuses eine Erhöhung der Strahlcharakteristik.Such air outlets are generally known and enable the generation of a displacement flow with which pollutants can be removed from the area where a room is located without any significant turbulence. For this purpose, the individual air jets are introduced into the room with little turbulence and with little induction. While the perforated plate or sieve forming the jacket of the induction housing ensures an equalization of the supply air distribution over the height and the circumference of the outlet, the nozzles in the jacket of the outer housing increase the jet characteristics.
Mit den bekannten Luftauslässen dieser Art ist eine Veränderung der Richtung der in den Raum eintretenden Luftstrahlen nur möglich, wenn aufwendige Vorkehrungen getroffen sind, um die Düsen im Mantel des Außengehäuses entsprechend verstellen zu können. Je nach Raumtemperatur ist es sehr erwünscht, die Luftstrahlen mehr oder weniger steil von oben nach unten oder von unten nach oben oder aber auch mehr oder weniger waagerecht in den Raum einzuleiten.With the known air outlets of this type, a change in the direction of the air jets entering the room is only possible if complex precautions are taken in order to be able to adjust the nozzles in the jacket of the outer housing accordingly. Depending on the room temperature, it is very desirable to introduce the air jets into the room more or less steeply from top to bottom or from bottom to top or also more or less horizontally.
Der Erfindung liegt die Aufgabe zugrunde, einen Luftauslaß der eingangs beschriebenen Art vorzuschlagen, bei dem sich die Strahlrichtung der Düsen wahlweise verändern läßt, ohne daß dazu die Düsen verstellt werden müssen, so daß auf entsprechend aufwendige Düsenausbildungen und Verstelleinrichtungen für diese verzichtet werden kann.The invention has for its object to propose an air outlet of the type described in the introduction, in which the jet direction of the nozzles can optionally be changed without the need to adjust the nozzles, so that correspondingly complex nozzle designs and adjusting devices can be dispensed with.
Zur Lösung dieser Aufgabe wird von einem Luftauslaß der im Oberbegriff des Anspruchs 1 genannten gattungsgemäßen Art ausgegangen, welcher erfindungsgemäß die im kennzeichnenden Teil desselben angegebenen Merkmale aufweist.To solve this problem, an air outlet of the generic type mentioned in the preamble of
Durch die erfindungsgemäße Klappe an einer Stirnseite des Außengehäuses läßt sich in Abhängigkeit von der Klappenöffnungsstellung ein mehr oder weniger großer Volumenstrom über die durch die Klappe im übrigen auch gänzlich verschließbare stirnseitige Öffnung unmittelbar in den Raum einleiten. Da die Düsen im Mantel des Außengehäuses in einer der Klappe benachbarten Ebene angeordnet sind, wird die Strahlrichtung der Düsen in Abhängigkeit vom Öffnungsgrad der Klappe hochwirksam beeinflußt, so daß sich eine Veränderung der Düsenstrahlrichtung durch eine einfache Verstellung der Klappe herbeiführen läßt. Durch den Abstand, mit dem das Innengehäuse zur Ebene der Klappe endet, läßt sich zudem auch in Schließstellung der Klappe die Düsenstrahlrichtung beeinflussen. Je größer dieser Abstand gewählt wird, desto weniger werden die Zuluftstrahlen beispielsweise nach unten abfallen, wenn sie kälter als die Raumluft sind.Due to the flap according to the invention on one end face of the outer housing, depending on the flap opening position, a more or less large volume flow can be introduced directly into the room via the front opening which can also be completely closed by the flap. Since the nozzles in the Sheath of the outer housing are arranged in a plane adjacent to the flap, the jet direction of the nozzles is influenced in a highly effective manner depending on the degree of opening of the flap, so that a change in the jet direction can be brought about by simply adjusting the flap. The distance at which the inner housing ends from the level of the flap can also influence the jet direction in the closed position of the flap. The larger this distance is selected, the less the supply air jets will fall down, for example, if they are colder than the room air.
Mit der Klappe lassen sich gleichfalls die Zuluftstrahlen in einfacher Weise gezielt so umlenken, daß - je weiter die Klappe geöffnet ist - die Luftstrahlen umso mehr von der waagerechten in die senkrechte Richtung umgelenkt werden. Dadurch läßt sich, falls der Luftauslaß über einem Aufenthaltsbereich angeordnet ist, in einem Heizfall eine schnellere Erwärmung des Bereichs erzielen. In einem Kühlfall läßt sich individuell mit einem vertikal eingeleiteten Luftstrahl der Aufenthaltsbereich kurzfristig intensiv durchspülen. Um auf Dauer Zugerscheinungen zu vermeiden, kann anschließend wiederum in erforderlicher Weise eine Richtungsänderung der Luftstrahlen vorgenommen werden.With the flap, the supply air jets can also be deflected in a simple manner in such a way that - the further the flap is opened - the more the air jets are deflected from the horizontal to the vertical direction. In this way, if the air outlet is arranged above a residence area, the area can be heated more quickly in the event of heating. In a cooling case, the lounge area can be flushed out intensively for a short time with a vertically introduced air jet. In order to avoid drafts in the long run, a change of direction of the air jets can then again be carried out as required.
Nach einer Ausgestaltung der Erfindung sind an einer Stirnseite des Außengehäuses zwei um eine Achse schwenkbare Klappen gelagert, wobei die Achse den Grundriß des Außengehäuses in zwei gleich große Flächen unterteilt.According to one embodiment of the invention, two flaps pivotable about an axis are mounted on an end face of the outer housing, the axis dividing the outline of the outer housing into two equal-sized surfaces.
Durch diese Ausgestaltung läßt sich der unmittelbar aus dem Luftauslaß austretende Volumenstrom in zwei Teilströme aufteilen.This configuration allows the volume flow emerging directly from the air outlet to be divided into two partial flows.
Vorzugsweise sind die Klappen unabhängig voneinander schwenkbar auf der Achse gelagert, so daß die Richtung jedes Teilstroms und die Intensität der Beeinflussung der benachbarten Düsen im Mantel des Gehäuses variierbar sind.Preferably, the flaps are pivoted independently of one another on the axis, so that the direction of each partial flow and the intensity of the influence of the adjacent nozzles in the casing of the housing can be varied.
Schließlich sieht eine Ausgestaltung der Erfindung noch vor, daß der Stutzen teleskopartig mit dem Innengehäuse verbunden und dessen Eindringtiefe in das Außengehäuse variierbar ist.Finally, an embodiment of the invention provides that the connecting piece is connected telescopically to the inner housing and the depth of penetration into the outer housing can be varied.
Durch diese Ausgestaltung läßt sich insbesondere bei geschlossener Klappe gleichfalls die Strahlrichtung der Düsen beeinflussen.This configuration also allows the jet direction of the nozzles to be influenced, in particular when the flap is closed.
