Abstract

The inlet valve is mounted in a circular recess in the floor over a central inlet port (4) leading to a circular distribution chamber. A circular plate (10) with lipped edges (12) covers radial outlet slots (6,7) spaced around the valve and with alternate slots having different outlet angles. At least two different outlet angles (8,9) are fitted to provide a spread in the outlet flow pattern into the room, e.g. air inlet distribution. The valve includes a spring loaded valve plate (15) which can be depressed against spring pressure via a central knob (20) to lock into a closed position held by a ratchet. <IMAGE>

Description

Die Erfindung betrifft einen Bodenquellauslaß aus einem zylindrischen Gehäuse mit einer bodenseitig koaxial angeordneten Einströmöffnung und einer konzentrisch zu dieser deckenseitig angeordneten Ringscheibe. Diese ist mit gleichmäßig verteilten, radial ausgerichteten Ausströmschlitzen versehen.The invention relates to a bottom source outlet from a cylindrical housing with an inlet opening arranged coaxially on the bottom and one concentrically to this ring disc arranged on the ceiling. This is even with distributed, radially aligned outflow slots.

Bei einem derartigen, aus der DE 39 28 621 A1 bekannten Bodenquellauslaß besteht das Gehäuse aus einem zylindrischen Stutzen mit einem konzentrischen Einsatz. Der Stutzen ist mit einem sich radial nach außen bogenförmig erweiternden Kragen versehen, der in einen auf dem Rand einer Bodenöffnung aufliegenden Flansch übergeht. Der sich von oben nach unten trichterförmig verengende Einsatz bildet in der Ebene des am Stutzen angeschlossenen Flansches eine Ringscheibe, in welcher radial ausgerichtete Ausströmschlitze in gleichmäßiger Verteilung vorgesehen sind. Eine äußere radiale Begrenzung erfahren die Ausströmschlitze einheitlich durch den sich bogenförmig erweiternden Kragen des Stutzens.With such a floor source outlet known from DE 39 28 621 A1 the housing consists of a cylindrical nozzle with a concentric one Commitment. The spigot is with a radially outward widening Provide collar that in a resting on the edge of a floor opening Flange merges. The one that narrows from top to bottom in a funnel shape Insert forms in the plane of the flange connected to the socket an annular disc in which radially aligned outflow slots in a uniform Distribution are provided. They experience an outer radial limitation Outflow slits uniformly through the arched collar of the neck.

Die vorstehend beschriebene Ausbildung des bekannten Bodenquellauslasses bewirkt durch die einheitliche bogenförmige äußere radiale Begrenzung der Ausströmschlitze, daß die Zuluft extrem flach und mit relativ hoher Geschwindigkeit über den Fußboden strömend in den Raum eingeblasen wird. Ersetzt man die bogenförmige radiale Begrenzung der Ausströmschlitze durch eine im wesentlichen vertikal ausgerichtete Begrenzung, wird die Zuluft senkrecht in den Raum geblasen.The above-described design of the known floor source outlet caused by the uniform arcuate outer radial limitation of the outflow slots, that the supply air is extremely flat and at a relatively high speed is blown into the room flowing over the floor. If you replace it arcuate radial limitation of the outflow slots by an essentially vertically oriented limitation, the supply air is vertical into the room blown.

Der Erfindung liegt die Aufgabe zugrunde, einen Bodenquellauslaß vorzuschlagen, der es ermöglicht, die Zuluft mit einem trombenförmigen Strömungsbild sprudelartig in den Raum einzuleiten. The invention has for its object to propose a floor source outlet, which allows the supply air to flow in a trombone shape initiate into the room like a bubble.

Zur Lösung dieser Aufgabe wird von einem Bodenquellauslaß der im Oberbegriff des Anspruchs 1 beschriebenen Art ausgegangen, der erfindungsgemäß die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale aufweist.To solve this problem is a floor source outlet in the preamble of claim 1 described type, according to the invention the im characterizing part of claim 1 specified features.

Durch die erfindungsgemäße unterschiedliche Ausbildung der schmalseitigen Schlitzlaibungen, indem diese abwechselnd durch eine schiefe Ebene mit kleinerem Neigungsgrad und eine schiefe Ebene mit größerem Neigungsgrad definiert sind, tritt die Zuluft nicht in zwei divergierenden Gruppen von Einzelstrahlen aus, die sich in zunehmender Entfernung vom Quellauslaß gleichfalls voneinander entfernen, sondern die benachbarten Zuluftstrahlen beeinflussen sich in besonders vorteilhafter Weise, indem sich die Strahlen beider Gruppen intensiv miteinander vermischen und das angestrebte trombenförmige Strömungsbild erzeugen.Due to the different design of the narrow-sided Slit reveals by alternating through an inclined plane with a smaller one Degree of inclination and an inclined plane with a greater degree of inclination are defined the supply air does not come out in two diverging groups of individual jets, which also differ from one another as the distance from the source outlet increases remove, but the neighboring supply air jets influence each other in particular advantageously by the rays of the two groups interacting intensely with one another mix and create the desired flow-shaped flow pattern.

Nach einer Ausgestaltung der Erfindung sind radial innen liegende schmalseitige Schlitzlaibungen jeweils von einer den Schlitzausströmquerschnitt verengenden Zunge überlagert.According to one embodiment of the invention, radially inner are narrow-sided Slot reveals each from a narrowing the slot outflow cross-section Tongue overlaid.

Durch diese Ausgestaltung entsteht bei sämtlichen Ausströmschlitzen in der Ebene ihres Ausströmquerschnitts eine scharfkantige Strömungsumlenkung, durch welche die Ausbreitung der Zuluftströmung insgesamt vergößert wird.This configuration results in all outflow slots in the Level of their outflow cross-section a sharp-edged flow deflection, through which the spread of the supply air flow is increased overall.

Vorzugsweise ist bei den Ausströmschlitzen, deren schmalseitige Schlitzlaibung den geringeren Neigungsgrad aufweist, der jeweilige Schlitzeinströmquerschnitt durch die Zunge vollständig überlagert.In the case of the outflow slots, their narrow-sided slot reveal is preferred has the lower degree of inclination, the respective slot inflow cross section completely overlaid by the tongue.

Durch diese Ausgestaltung wird die unterschiedliche Wirkung der benachbarten Ausströmschlitze noch verstärkt, indem die Zungenspitzen abwechselnd einen Einströmquerschnitt vollständig und einen folgenden Einströmquerschnitt nur teilweise überlagern. This configuration makes the different effect of the neighboring one Outflow slots are reinforced by the tip of the tongue alternately Inflow cross section complete and a subsequent inflow cross section only partially overlay.

Nach einer weiteren Ausgestaltung der Erfindung sind die radial innen liegenden schmalseitigen Schlitzlaibungen auf einem größeren Durchmesser angeordnet als der Durchmesser der Einströmöffnung des Gehäuses, wobei diese durch eine im Gehäuse höhenverstellbar gelagerte Absperrscheibe verschließbar ist.According to a further embodiment of the invention, the radially inner Narrow-sided slit reveals arranged on a larger diameter than the diameter of the inflow opening of the housing, this by an im Shut-off disk with adjustable height is lockable.

Durch diese Ausgestaltung bleiben die Ausströmschlitze unabhängig von der Position der Absperrscheibe durch diese unbeeinflußt.With this configuration, the outflow slots remain independent of the Position of the shut-off disc unaffected by this.

Um die Einströmöffnung des Quelluftauslasses mit einem Handgriff wahlweise absperren und freigeben zu können, sieht schließlich noch eine Ausgestaltung der Erfindung vor, daß die Absperrscheibe mit Hilfe eines durch eine zentrische Bohrung in einen Deckel des Gehäuses einführbaren Stift gegen die Wirkung einer Druckfeder in die untere Schließposition verlagerbar ist und durch eine an sich bekannte Rasterverriegelung verriegelbar sowie entriegelbar. und durch die Wirkung der Druckfeder in die obere Öffnungsposition verlagerbar ist.Optionally around the inflow opening of the source air outlet with a handle Finally, being able to lock and unlock a configuration the invention that the shut-off disc with the help of a through a central Hole in a cover of the housing insertable pin against the effect a compression spring in the lower closed position and by a known grid lock can be locked and unlocked. and through that Effect of the compression spring in the upper open position is shiftable.

and
Fig. 2
a floor plan of the outlet.

Der Bodenquellauslaß umfaßt ein im wesentlichen zylindrisches Gehäuse 1, das in eine Öffnung eines Fußbodens 2 einsetzbar ist, unter dem sich ein Zuluft zuführender Hohlraum befindet. In einem Boden 3 des Gehäuses 1 ist konzentrisch eine Einströmöffnung 4 vorgesehen, über welche der Bodenquellauslaß über den Hohlraum mit Zuluft beaufschlagt wird. The bottom source outlet comprises a substantially cylindrical housing 1 which can be inserted into an opening in a floor 2, under which there is a supply air feeding cavity. In a bottom 3 of the housing 1 is concentric an inflow opening 4 is provided, through which the bottom source outlet is supplied with supply air via the cavity.

Wie insbesondere Fig. 2 verdeutlicht, ist das Gehäuse 1 deckenseitig mit einer Ringscheibe 5 versehen, in der radial ausgerichte Ausströmschlitze 6 und 7 vorgesehen sind. Abwechselnd folgt einem Ausströmschlitz 6 ein Ausströmschlitz 7.As is particularly clear in FIG. 2, the housing 1 is on the ceiling side with a Washer 5 provided in the radially aligned outflow slots 6 and 7 provided are. An outflow slot 6 is alternately followed by an outflow slot 7.

Wie die Querschnittsdarstellung in Fig. 1 veranschaulicht, sind die Ausströmschlitze 6 und 7 mit einer radial außen liegenden schmalseitigen Schlitzlaibung 8 bzw. 9 versehen. Diese sind jeweils durch eine schiefe Ebene mit unterschiedlichem Neigungsgrad definiert, wobei die Schlitzlaibung 8 einen geringeren Neigungsgrad als die Schlitzlaibung 9 aufweist.As the cross-sectional illustration in FIG. 1 illustrates, the outflow slots are 6 and 7 with a radially outer narrow slit reveal 8 or 9 provided. These are each different on an inclined plane Defines degree of inclination, the slit reveal 8 having a lower degree of inclination than the slit reveal 9.

Innerhalb der Ringscheibe 5 ist eine mit Teppichboden 10 oder dergleichen verkleidete, kreisrunde Abdeckplatte 11 eingesetzt, die mit einem radial nach außen vorstehenden Kragen im Bereich der Ausströmschlitze 6 und 7 Zungen 12 bildet. Diese überragen jeweils eine radial innen liegende schmalseitige Schlitzlaibung 13 der Ausströmschlitze 6 und 7. Während der jeweilige Einströmquerschnitt der Ausströmschlitze 6 infolge der geringer geneigten Schlitzlaibung 8 von einer Zunge 12 vollständig überlagert ist, wird der Einströmquerschnitt der Ausströmschlitze 7 infolge der steileren Schlitzlaibung 9 nur teilweise überlagert.Inside the washer 5 is a carpet 10 or the like, circular cover plate 11 used with a radially outward protruding collar in the area of the outflow slots 6 and 7 tongues 12 forms. These each protrude from a radially inner narrow-side slit reveal 13 of the outflow slots 6 and 7. During the respective inflow cross section the outflow slots 6 due to the less inclined slot reveal 8 of one Tongue 12 is completely overlaid, the inflow cross section of the outflow slots 7 due to the steeper slot reveal 9 only partially overlaid.

Der Bodenquellauslaß ist aus der dargestellten aktiven Offenstellung in einfacher Weise in eine passive Schließstellung überführbar. Dazu ist im Gehäuse 1 eine über senkrechte Stege 14 geführte Absperrscheibe 15 gegen die Wirkung einer Druckfeder 16 auf einen elastischen Ringwulst 17 am Rand der Einströmöffnung 4 absenkbar und durch eine an sich bekannte Rasterverriegelung arretierbar. Diese kann so ausgebildet sein, wie sie bei Kugelschreibern Verwendung findet, wobei die Kugelschreibermine zwischen zwei Endposition axial verschiebbar gelagert ist und durch eine einfache Druckknopfbetätigung wechselweise in der einen oder anderen Position fixierbar ist. Beim dargestellten Ausführungsbeispiel ist der Absperrscheibe 15 konzentrisch ein entsprechender Druckknopf 16 zugeordnet, der sich mit einem einfachen, nicht dargestellten Stift betätigen läßt. Dazu ist im Teppichboden 10 und in der Abdeckplatte 11 1 eine zum Druckknopf 16 koaxiale Bohrung 18 vorgesehen, durch die sich der Stift zur Betätigung einführen läßt. Durch einen mit dem Stift auf den Druckknopf 16 ausgeübten Druck kann die über drei Distanzbolzen 19 gegen die Unterseite der Abdeckplatte abgestützte Absperrscheibe 15 in die untere Absperrposition verschoben und darin verriegelt werden. Mit dem gleichen Stift erfolgt gleichfalls die Entriegelung der Abdeckplatte 11, so daß diese durch den Druck der Feder 16 in die dargestellte Offenstellung angehoben und darin gehalten wird.The bottom source outlet is easier from the active open position shown Can be converted into a passive closed position. For this is in the housing 1 Shut-off disk 15 guided over vertical webs 14 against the action of a Compression spring 16 on an elastic annular bead 17 at the edge of the inflow opening 4 can be lowered and locked using a grid lock known per se. This can be designed as it is used in ballpoint pens, the ballpoint pen refill axially displaceable between two end positions is stored and alternately in the by a simple push button one or the other position is fixable. In the illustrated embodiment the shut-off disk 15 is concentrically a corresponding push button 16 assigned, which operate with a simple, not shown pen leaves. For this is in the carpet 10 and in the cover plate 11 1 to the push button 16 coaxial bore 18 is provided through which the pin for actuation can be introduced. By one exerted on the push button 16 with the pen Pressure can over the three spacers 19 against the bottom of the Cover plate supported shut-off disc 15 in the lower shut-off position moved and locked in it. The same pen is also used unlocking the cover plate 11 so that this by the pressure of the spring 16 is raised to the open position shown and held therein.
