Abstract

The air outlet device (1) has in a rectangular air duct (10) horizontal and vertical air-conducting lamellae (5, 4) mounted pivotably on its shaft (22). The horizontal lamellae (5) are connected to a common drive which consists of a cylinder/piston unit (11). The cylinder (12) of this drive is connected to a closed tubular container (13) which is filled with a medium capable of flowing and which extends over a major part of the opening cross-section of the air duct (10). When the temperature of the air flowing through the device changes, the cylinder/piston unit, as a result of the expansion of this medium, displaces a drive plate (16), the rack-like toothing (24) of which engages in toothed wheels (23) which are fastened to the end of each horizontal lamella (5). The drive is built into the air outlet device (1) in a compact manner and so as to be immune to faults. The air outlet device makes possible automatic optimum adjustment of the lamellae (5) which determine the upward or downward flow of the air flowing out of the device (1). The inclination of the lamellae (5), which corresponds to a given air temperature, can be adjusted by hand by means of a tool. <IMAGE>

Eine Luftauslassvorrichtung dieser Art ist bekannt durch die DE-A-32 04 613 der gleichen Anmelderin. Der Antrieb dieser bekannten Vorrichtung ist ein Stellmotor mit einem Reduktionsgetriebe, und die Verschiebung der Antriebsplatte erfolgt durch den Eingriff eines Exzenterstiftes in einen Schlitz der Platte. Für eine temperaturabhängige Einstellung der Neigung der Luftführungslamellen ist eine elektrische Steuerung mit einem Temperaturfühler erforderlich.An air outlet device of this type is known from DE-A-32 04 613 by the same applicant. The drive of this known device is a servomotor with a reduction gear, and the displacement of the drive plate is effected by the engagement of an eccentric pin in a slot in the plate. An electrical control with a temperature sensor is required for a temperature-dependent adjustment of the inclination of the air duct slats.

Der Erfindung liegt die Aufgabe zugrunde, eine Luftauslassvorrichtung der eingangs genannten Art zu finden, die bei einfacher, raumsparender und robuster Ausführung ihres Antriebes als Massenprodukt besonders preiswert herstellbar ist und eine selbsttätige Verstellung der Neigung ihrer Luftführungslamellen in direkter Abhängigkeit von der Temperatur der sie durchströmenden Luft bei ausreichendem Verstellwinkel ermöglicht. Die Lösung dieser Aufgabe erfolgt aufgrund der kennzeichnenden Merkmale des Anspruchs 1.The invention has for its object to find an air outlet device of the type mentioned, which is particularly inexpensive to manufacture with a simple, space-saving and robust design of its drive as a mass product and an automatic adjustment of the inclination of their air duct slats in direct dependence on the temperature the air flowing through them with a sufficient adjustment angle. This object is achieved on the basis of the characterizing features of claim 1.

Die Zylinder-Kolbeneinheit sowie die in Gegenrichtung zu ihr wirkende Feder lassen sich sehr raumsparend an der Vorrichtung bzw. an ihrem Schacht vorsehen, so dass die Montage der Vorrichtung im Wandausschnitt eines Luftkanals nicht behindert wird und keine Behinderung des Strömungsweges erfolgt. Der das sich thermisch ausdehnende Antriebsmedium einschliessende Behälter kann als verhältnismässig langes Rohr sich über den Durchlassquerschnitt der Vorrichtung erstrecken, so dass er bei grosser Wärmeübertragungsfläche ein ausreichendes Speichervolumen aufweist, um den Kolben des Antriebs bei Temperaturveränderung um eine Länge zu verschieben, die einem ausreichenden Verstellwinkel der Luftführungslamellen entspricht.The cylinder-piston unit and the spring acting in the opposite direction to it can be provided in a very space-saving manner on the device or on its shaft, so that the assembly of the device in the wall cutout of an air duct is not hindered and the flow path is not obstructed. The container enclosing the thermally expanding drive medium can extend as a relatively long tube over the passage cross-section of the device, so that with a large heat transfer surface it has a sufficient storage volume to move the piston of the drive by a length in the event of a change in temperature which corresponds to a sufficient adjustment angle Air guide fins corresponds.

In vorteilhafter Ausführungsform der Erfindung ist die Zylinder-Kolbeneinheit mit einer Schraubvorrichtung kombiniert, die eine Einstellung der einer vorgegebenen Temperatur entsprechenden Neigung der luftführenden Lamellen ermöglicht.In an advantageous embodiment of the invention, the cylinder-piston unit is combined with a screwing device which enables the inclination of the air-guiding fins corresponding to a predetermined temperature to be set.

Weiterer Gegenstand der Erfindung ist ein Einstellwerkzeug für die Betätigung der genannten Schraubvorrichtung, das als kombiniertes Werkzeug ausgeführt sein kann, um ausserdem Lamellen in ihrer luftführenden Richtung durch Betätigung von Hand einzustellen, die nicht mit dem genannten Antrieb verbunden sind.Another object of the invention is an adjusting tool for the actuation of said screwing device, which can be designed as a combined tool, in addition to adjust lamellae in their air-guiding direction by manual actuation, which are not connected to said drive.

Luftauslassvorrichtungen 1 entsprechend den Darstellungen der Fig.1 bis 4 sind bekannt und in praktischer Anwendung in zahlreichen Räumen, wie Fabrikationshallen, Restaurants u.dgl. zu finden. Sie bilden Teil einer Klimaanlage, indem sie hintereinander, wie in Fig.1 gezeigt, in Wandausschnitten 2 eines von einem zentralen Lufterhitzer und/oder einem Luftkühler kommenden Luftkanals 3 montiert sind. Die Luftauslassvorrichtungen geben durch ihre zahlreichen vertikalen und horizontalen luftführenden Lamellen 4,5 der in Richtung der Pfeile 6 aus dem Luftkanal 3 ausströmenden Luft die gewünschte Richtung beim Eintritt in den zu klimatisierenden Raum. Ein an der Rückseite der Luftauslassvorrichtung vorzugsweise vorgesehener Luftverteilkasten 7 erstreckt sich in Längsrichtung des Luftkanals zunehmend in diesen hinein, so dass die Luft gleichmässig über den Oeffnungsquerschnitt der Luftauslassvorrichtung 1 verteilt wird.Air outlet devices 1 according to the representations of Figures 1 to 4 are known and in practical use in numerous rooms, such as manufacturing halls, restaurants and the like. to find. They form part of an air conditioning system in that, one behind the other, as shown in FIG. 1, in wall sections 2 one of a central air heater and / or an air cooler coming air duct 3 are mounted. Due to their numerous vertical and horizontal air-guiding fins 4, 5, the air outlet devices give the air flowing out of the air duct 3 in the direction of the arrows 6 the desired direction when entering the room to be air-conditioned. An air distribution box 7, which is preferably provided on the rear side of the air outlet device, extends increasingly into the longitudinal direction of the air duct, so that the air is distributed uniformly over the opening cross section of the air outlet device 1.

Die gewünschte Strömungsrichtung der aus den Luftauslassvorrichtungen ausströmenden Luft oder die optimale Strömungsrichtung ist,hinsichtlich ihres in einer vertikal zum Luftkanal 3 verlaufenden Ebene gemessenen Neigungswinkels,abhängig von der Temperaturdifferenz zwischen der ausströmenden Luft und der Raumlufttemperatur. Vorteilhaft wird kalte Luft aufwärts in den Raum,ausgehend von einem über Kopfhöhe verlaufenden Luftkanal 3, ausgeblasen, so dass sich eine grosse Wurfweite der Kaltluft ergibt, ohne dass Personen direkt angeblasen werden können. Warmluft für die schnelle und energiesparende Aufheizung eines Raumes hingegen wird möglichst steil nach unten gegen den Boden in den Raum eingeblasen,von wo aus sie nach Abgabe eines Teiles ihrer Wärme verlangsamt nach oben steigt. Fig.5 und Fig.6 zeigen Beispiele der Ausströmrichtungen für bestimmte Temperaturen, wie sie durch eine erfindungsgemässe Luftauslassvorrichtung selbsttätig eingestellt werden, indem die horizontalgerichteten Lamellen in einem Winkel von maximal ca. 100° geschwenkt werden. Die dargestellten Beispiele zeigen eine vorgegebene Einstellung derart, dass bei einer Temperatur von 20°C die Ausströmung in horizontaler Richtung erfolgt. Wie im folgenden noch näher beschrieben wird, kann die vorgegebene Einstellung an dem Antrieb der erfindungsgemässen Luftauslassvorrichtung verstellt werden.The desired flow direction of the air flowing out of the air outlet devices or the optimal flow direction is, depending on the angle of inclination measured in a plane running vertically to the air duct 3, dependent on the temperature difference between the flowing air and the room air temperature. Cold air is advantageously blown upwards into the room, starting from an air duct 3 running above head height, so that there is a large throw of the cold air without people being able to be blown directly. Warm air for the fast and energy-saving heating of a room, on the other hand, is blown down as steeply as possible against the floor into the room, from where it slowly rises after giving off part of its heat. 5 and 6 show examples of the outflow directions for certain temperatures as they are automatically set by an air outlet device according to the invention by pivoting the horizontally oriented slats at an angle of at most approx. 100 °. The examples shown show a predefined setting such that the outflow takes place in a horizontal direction at a temperature of 20 ° C. As will be described in more detail below, the predefined setting on the drive of the air outlet device according to the invention can be adjusted.

Der die selbsttätige Verstellung der Neigung der horizontalen Lamellen 5 bewirkende Antrieb 8 ist nahezu in der Ebene einer schmalseitigen Wand 9 des Luftschachtes 10 der Luftauslassvorrichtung angeordnet, so dass er die Aussenabmessungen der Vorrichtung bzw. ihres Luftschachtes nicht wesentlich vergrössert und die Montage der Vorrichtung in einem Ausschnitt 2 des Luftkanals 3 nicht behindert.The automatic adjustment of the inclination of the horizontal Lamella 5 causing drive 8 is arranged almost in the plane of a narrow-sided wall 9 of the air shaft 10 of the air outlet device, so that it does not significantly increase the external dimensions of the device or its air shaft and does not hinder the assembly of the device in a cutout 2 of the air duct 3.

Der Antrieb 8 hat eine Kolben-Zylindereinheit 11, deren Zylinder 12 mit einem rohrförmigen Behälter 13 verbunden ist. Dieser sonst dicht verschlossene Behälter ist mit einem sich verhältnismässig stark bei Erwärmung ausdehnenden strömungsfähigen Medium, wie z.B. "Freon",gefüllt und erstreckt sich bogenförmig über den Oeffnungsquerschnitt des Luftschachtes 10 der Luftauslassvorrichtung 1. Die aus der Luftauslassvorrichtung ausströmende Luft umströmt somit diesen rohrförmigen Behälter, so dass sich bei Temperaturerhöhung das eingeschlossene Medium ausdehnt und in den Zylinder 12 einströmt, wo es den im Zylinder geführten Kolben, bzw. dessen Kolbenstange 14 verschiebt. Die Bewegung der Kolbenstange, die entgegen der Kraft einer zu der Zylinder-Kolbeneinheit 11 parallel angeordneten Zugfeder 15 erfolgt, überträgt sich auf eine Antriebsplatte 16, indem ein sich L-förmig von dieser wegerstreckender Arm 17 in einen Schlitz im äusseren Ende der Kolbenstange 14 eingreift. Das Ende der Kolbenstange greift ausserdem in einen diesem angepassten Auschnitt 19 ein. Die Zugfeder 15 ist einerseits mit dem äusseren Ende des Plattenarmes 17 und andererseits an einer Konsole 20 befestigt, an der auch der Zylinder 12 des Antriebs gehalten ist. Die Zugfeder 15 hält somit den Plattenarm an der Kolbenstange und bewegt die Antriebsplatte bei Temperaturerniedrigung der ausströmenden Luft zurück.The drive 8 has a piston-cylinder unit 11, the cylinder 12 of which is connected to a tubular container 13. This otherwise tightly closed container is filled with a fluid medium that expands comparatively strongly when heated, e.g. "Freon", filled and extends in an arc over the opening cross section of the air shaft 10 of the air outlet device 1. The air flowing out of the air outlet device thus flows around this tubular container, so that when the temperature rises, the enclosed medium expands and flows into the cylinder 12, where it flows piston guided in the cylinder or its piston rod 14 moves. The movement of the piston rod, which takes place against the force of a tension spring 15 arranged parallel to the cylinder-piston unit 11, is transmitted to a drive plate 16 by an arm 17 extending in an L-shape from it engaging in a slot in the outer end of the piston rod 14 . The end of the piston rod also engages in a cutout 19 adapted to this. The tension spring 15 is fastened on the one hand to the outer end of the plate arm 17 and on the other hand to a bracket 20 on which the cylinder 12 of the drive is also held. The tension spring 15 thus holds the plate arm on the piston rod and moves the drive plate back when the temperature of the outflowing air drops.

Die Antriebsplatte 16 steht in Antriebsverbindung mit den temperaturabhängig zu verstellenden horizontalen Lamellen 5. Hierfür ist an der Schwenkachse 22 jeder Lamelle 5 ein Zahnrad 23 befestigt und an der Antriebsplatte 16 eine zahnstangenartige Verzahnung 24 vorgesehen, die mit den Zahnrädern 23 kämmt. Die geradlinige Führung der Bewegung dar Antriebsplatte wird durch mindestens zwei Führungsringe 26,27 erreicht, die in auf gleicher Linie verlaufende gerade Schlitze 28,29 der Antriebsplatte eingreifen. Seitlich ist die Hubbewegung der Antriebsplatte zwischen der Schachtwand 9 und einer parallel zu ihr befestigten Führungsplatte 30 geführt. Die Führungsringe 26,27 bilden dabei gleichzeitig Distanzringe für die Führungsplatte. Sie sind jeweils durch eine Schraube 32 an der Schachtwand befestigt Ausserdem stützt sich ein abgebogenes Ende 33 der Führungsplatte distanzhaltend an der Schachtwand 9 ab.The drive plate 16 is in drive connection with the temperature-dependent horizontal slats 5. For this purpose, a gear 23 is attached to the pivot axis 22 of each slat 5 and a rack-like toothing 24 is provided on the drive plate 16, which meshes with the gear wheels 23. The linear guidance of the movement of the drive plate is achieved by at least two guide rings 26, 27 which engage in straight slots 28, 29 of the drive plate which run in the same line. The lifting movement of the drive plate is guided laterally between the shaft wall 9 and a guide plate 30 fastened parallel to it. The guide rings 26, 27 simultaneously form spacer rings for the guide plate. They are each fastened to the shaft wall by a screw 32. In addition, a bent end 33 of the guide plate is supported on the shaft wall 9 to keep it at a distance.

Im dargestellten bevorzugten Ausführungsbeispiel der Luftauslassvorrichtung 1 ist ein Nabenteil 35 der Zahnräder 23 in einer Bohrung der Führungsplatte 30 gelagert , der die Achse 22 der jeweiligen Lamelle 5 hält, und die Führungsplatte 30 ist an der Innenseite der Schachtwand 9 befestigt. Die Zahnräder 23 befinden sich somit in dem gleichen Spaltraum 36 wie die Antriebsplatte und sind dort ebenfalls seitlich geführt. Der Antriebsmechanismus befindet sich folglich geschützt innerhalb des Luftschachtes 10 der Luftauslassvorrichtung.In the preferred exemplary embodiment of the air outlet device 1 shown, a hub part 35 of the gear wheels 23 is mounted in a bore in the guide plate 30, which holds the axis 22 of the respective lamella 5, and the guide plate 30 is fastened to the inside of the shaft wall 9. The gears 23 are thus in the same gap 36 as the drive plate and are also guided laterally there. The drive mechanism is thus protected inside the air duct 10 of the air outlet device.

Die Konsole 20, die den Zylinder 12 der antreibenden Kolben-Zylindereinheit 11 hält, umschliesst diese nach aussen schalenförmig, wie die Fig. 13 zeigt, so dass sie ebenfalls gegen Beschädigung beim Transport oder bei der Montage der Luftauslassvorrichtung geschützt ist.The bracket 20, which holds the cylinder 12 of the driving piston-cylinder unit 11, surrounds it in a shell-like manner, as shown in FIG. 13, so that it is also protected against damage during transport or during assembly of the air outlet device.

In der Bodenwand 37 der schalenförmigen Konsole 20 ist eine Gewindebuchse 39 befestigt, in die der Gewindezapfen 40 einer kappenförmigen Zylinderfassung 41 eingreift, so dass diese durch Verdrehen um ihre Achse auf-und abwärts schraubbar ist, um die achsiale Position der Zylinder-Kolbeneinheit 11 und damit die einer bestimmten Temperatur der die Luftauslassvorrichtung durchströmenden Luft entsprechende Neigung der horizontalen luftführenden Lamellen einzustellen. Das Verdrehen der Zylinderfassung 41, bzw. dieses Einstellen erfolgt mit Hilfe eines stabförmigen Einstellwerkzeuges 43,das an einem sich verjüngenden Ende 44 eine zahnstangenartige Aussenverzahnung 45 aufweist, die von Hand in Eingriff mit einer Aussenverzahnung 46 der kappenförmigen Zylinderfassung 41 gebracht wird. Das Verschieben dieses stabförmigen Einstellwerkzeuges in seiner Längsrichtung, mit Andruck gegen die Verzahnung 46 bewirkt die genannte Einstellung. Das stabförmige Einstellwerkzeug lässt sich dabei zwischen den sich kreuzenden Lamellen 4,5 der Luftauslassvorrichtung von deren Vorderseite aus, bis zu der Zylinderfassung 41 hindurchschieben. Für die Einstellung der senkrechten, bei diesem Ausführungsbeispiel äusseren Reihe von Lamellen 4, die keine Verbindung mit einem Antrieb aufweisen, ist an dem der zahnstangenartigen Aussenverzahnung gegenüberliegenden Ende 48 des Einstellwerkzeuges ein Schlitz 49 vorgesehen, mit dem die Lamellen 4 einzeln erfasst werden können, um sie um ihre Achse in eine andere Position zu schwenken.In the bottom wall 37 of the cup-shaped bracket 20, a threaded bushing 39 is fastened, into which the threaded pin 40 of a cap-shaped cylinder holder 41 engages, so that it can be screwed up and down by rotating about its axis, about the axial position of the cylinder-piston unit 11 and thus adjusting the inclination of the horizontal air-guiding fins corresponding to a specific temperature of the air flowing through the air outlet device. The turning of the cylinder holder 41, or this adjustment, is carried out with the aid of a rod-shaped adjusting tool 43 has a rack-like external toothing 45 on a tapering end 44, which is brought into engagement by hand with an external toothing 46 of the cap-shaped cylinder mount 41. Moving this rod-shaped setting tool in its longitudinal direction, with pressure against the toothing 46, causes the setting mentioned. The rod-shaped adjusting tool can be pushed between the intersecting lamellae 4, 5 of the air outlet device from the front thereof up to the cylinder mount 41. For the adjustment of the vertical, in this exemplary embodiment outer row of slats 4, which have no connection to a drive, a slot 49 is provided at the end 48 of the adjusting tool opposite the rack-like external toothing, with which the slats 4 can be individually detected in order to swivel them around their axis to another position.
