Description

Dis Erfindung betrifft einen Luftbeimischer gemäß dem Anspruch 1.The invention relates to an air mixer according to claim 1.

Es ist bekannt, einen Luftbeimischer an dem vorderen Ende eines Wasserauslaufes einer Mischarmatur über ein Kugelgelenk zu befestigen. Hierbei ist das Kugelgelenk am Wasserauslauf befestigt und die Kugel besitzt einen Kanal, durch den das Wasser strömt. Unterhalb der Kugel ist ein Luftbeimischer angeordnet, dessen Ausstrahlrichtung aufgrund des Kugelgelenkes verstellbar ist. Eine solche Konstruktion führt zu einer erheblichen Bauhöhe, so dass ein verhältnismäßig großes Teil am Ende des Wasserauslaufs befestigt ist.It is known to attach a Luftbeimischer at the front end of a water outlet of a mixing fitting via a ball joint. Here, the ball joint is attached to the water outlet and the ball has a channel through which the water flows. Below the ball is a Luftbeimischer arranged whose Ausstrahlrichtung is adjustable due to the ball joint. Such a construction leads to a considerable height, so that a relatively large part is attached to the end of the water spout.

Aus der EP 0 190 965 A1 ist bereits ein Luftbeimischer vorbekannt, der über ein Kugelgelenk verschwenkbar gelagert und am vorderen Auslaufende des Wasserauslaufs einer Wasserarmatur lösbar befestigt ist. Der vom Wasser durchströmbare Luftbeimischer ist dazu zumindest teilweise innerhalb der Gelenkkugel des Kugelgelenks gelagert. Die Gelenkkugel weist dazu eine axiale Einsetzöffnung auf, in welche der Luftbeimischer von der Zuströmseite aus einsetzbar ist. Die Gelenkkugel hat an ihrem Außenumfang Federstege, die über die zuströmseitige Stirnseite der Gelenkkugel vorstehen. Um die den Luftbeimischer aufnehmende Gelenkkugel am vorderen Auslaufende des Wasserauslaufs der Wasserarmatur lösbar befestigen zu können, ist der das Auslaufende umgrenzende Wandungsinnenumfang der Auslaufarmatur als eine zur Gelenkkugel komplementäre Aufnahmehöhlung ausgestaltet. In dieser Aufnahmehöhlung ist die Gelenkkugel derart einsetzbar, dass die Raststege die Gelenkkugel in der Aufnahmehöhlung verschwenkbar sichern.From the EP 0 190 965 A1 Already a Luftbeimischer is already known, via a ball joint mounted pivotably and releasably secured to the front outlet end of the water outlet of a water faucet. The air mixer, which can be flowed through by the water, is at least partially mounted within the joint ball of the ball joint for this purpose. The ball joint has for this purpose an axial insertion opening into which the air admixer can be inserted from the inflow side. The joint ball has on its outer circumference spring webs which project beyond the inflow-side end face of the joint ball. In order to be able to releasably fix the ball of the ball receiving the air cleaner at the front outlet end of the water outlet of the water fitting, the wall inner circumference of the outlet fitting surrounding the outlet end is designed as a receiving cavity complementary to the ball joint. In this Aufnahmehöhlung the ball joint is used so that the locking webs secure the ball joint in the receiving cavity pivot.

Es ist ein besonderer Vorteil des aus EP 0 190 965 A1 vorbekannten Standes der Technik, dass in das Kugelgelenk grundsätzlich auch ein handelsüblicher Luftbeimischer-Einsatz eingesetzt werden kann. Schwerwiegender ist jedoch der Nachteil, die Wasserarmatur an ihrem Auslaufende innenumfangsseitig derart komplementär zur Gelenkkugel auszugestalten und auszuarbeiten, dass die Gelenkkugel darin eingesetzt werden kann. Die hohlkugelförmige Ausgestaltung der Wasserarmatur an ihrem Auslaufende ist jedoch mit einem erheblichen Aufwand verbunden.It's a special advantage of dating EP 0 190 965 A1 Prior art prior art, that in principle also a commercial Luftbeimischer use can be used in the ball joint. More serious, however, is the disadvantage of designing the water fitting at its outlet end on the inner peripheral side so complementary to the joint ball and work out that the ball joint can be used therein. However, the hollow spherical design of the water fitting at its outlet end is associated with a considerable effort.

Aus der DE 32 05 205 A1 kennt man bereits eine sanitäre Auslaufarmatur mit einem Armaturenauslauf, der an seinem freien abströmseitigen Endbereich eine Lagerfläche für eine Kugelgelenk-Kugel trägt. Die Lagerfläche weist einen quer verlaufenden Führungsschlitz auf, in den ein in der Kugel axial abragender Führungszapfen verdrehsicher gelagert ist, so dass die Kugelgelenk-Kugel nur in einer Ebene verschwenkt werden kann. Die Kugel ist auf der Lagerfläche mittels einem Griffstück gehalten, welches an dem abströmseitigen Endbereich des Armaturenauslaufs drehbar gelagert ist. Die Kugelgelenk-Kugel ist bei Drehung des Griffstücks mittels einer zwischen dem Griffstück und dem Auslaufendstück vorgesehenen Steuerschlitz-Steuerzapfen-Führung im Griffstück relativ zu diesem derart verschwenkbar gelagert, dass die Auslaufrichtung des durch die hohle Kugelgelenk-Kugel geführten Wasserstroms durch Drehen am Griffstück bei Bedarf geändert werden kann.From the DE 32 05 205 A1 One knows already a sanitary outlet fitting with a fitting outlet, which carries at its free downstream end portion a bearing surface for a ball joint ball. The bearing surface has a transverse guide slot into which a guide pin projecting axially in the ball is mounted against rotation, so that the Ball joint ball can only be pivoted in one plane. The ball is held on the bearing surface by means of a handle, which is rotatably mounted on the downstream end region of the valve outlet. The ball joint ball is rotatably mounted relative to this during rotation of the handle by means of a provided between the handle and the outlet end control slot control pin guide in the handle that the discharge direction of the guided through the hollow ball joint ball water stream by turning the handle when needed can be changed.

Diese bewegungsgetriebeartige Übersetzung einer vom Bediener aufgebrachten Drehbewegung um die Rohrlängsachse in eine Schwenkbewegung des Kugelstücks um eine Achse senkrecht zur Rohrlängsachse des Auslaufs stellt eine Bewegungsübersetzung dar, die eine aufwändig herzustellende, verschleiß- und schmutzanfällige Kinematik erfordert. Als besonders nachteilig ist auch der extreme Überarbeitungsaufwand der Bauteile und die Vielzahl der erforderlichen Bauteile zu sehen. Zudem erscheint der sehr große Platzbedarf als nachteilig, der die Lösung der Aufgabe, nämlich Verschwenken des Auslaufstrahls, optisch nie in den Hintergrund treten lässt. Schließlich muss die aus DE 32 05 205 A1 vorbekannte Auslaufarmatur speziell mit dem oben beschriebenen Armaturenauslauf ausgestaltet werden, so dass der Armaturenauslauf nicht in Verbindung mit einer bereits vorhandenen Auslaufarmatur verwendbar ist.This motion gear-like translation of an applied by the operator rotation about the tube longitudinal axis in a pivoting movement of the ball member about an axis perpendicular to the tube longitudinal axis of the spout represents a motion translation, which requires a complex to produce, wear and dirt-prone kinematics. Particularly disadvantageous is also the extreme workover of the components and the variety of required components to see. In addition, the very large space requirement appears to be disadvantageous, which visually never let the solution of the problem, namely pivoting of the discharge jet in the background. Finally, that must be out DE 32 05 205 A1 previously known outlet fitting specially designed with the above-described fitting outlet, so that the fitting outlet is not used in conjunction with an existing outlet fitting.

Aufgabe der Erfindung ist es, eine Wasserarmatur der eingangs erwähnten Art mit einem Luftbeimischer, dessen Teile vollständig oder teilweise vom Ende des Wasserauslaufs aufnehmbar sind, wobei der einen verschwenkbar einstellbaren Strahl erzeugende Luftbeimischer in den Auslaufenden aller Standardarmaturen einschraubbar ist.The object of the invention is a water fitting of the type mentioned with a Luftbeimischer whose parts are fully or partially from the end of the water outlet can be received, wherein the pivotable adjustable beam generating air mixer in the outlet ends of all standard fittings can be screwed.

Diese Aufgabe wird erfindungsgemäß durch der Gegenstand des Anspruchs 1 gelöst.This object is achieved by the subject matter of claim 1.

Der erfindungsgemäße Luftbeimischer weist auf seine dem Auslaufende zugewandten Seite einen Dichtring auf, der zwischen der Außenringinnenseite und entweder der Kugelzonenaußenseite oder der Luftbeimischeraußenseite einliegt. Dieser Dichtring liegt beim Einschrauben des Außenrings in den Wasserauslauf an einem Bereich im Inneren des Wasserauslaufs derart an, dass der Dichtring hierdurch verpresst wird. Da der Dichtring in der Ringzone zwischen der Außenringinnenseite und der Kugelzonenaußenseite bzw. der Luftbeimischeraußenseite anliegt, wird eine besonders einfache und sichere Abdichtung erreicht. Da sich der Dichtring in der Ringzone zwischen der Außenringinnenseite und der Kugelzonenaußenseite bzw. der Luftbeimischeraußenseite verpresst, lässt sich gleichzeitig auch die Relativposition zwischen dem Luftbeimischer und dem Außenring gegen ein unbeabsichtigtes Verschwenken sichern.The air blender according to the invention has on its side facing the outlet end a sealing ring, which rests between the outer ring inner side and either the ball zone outside or the Luftbeimischeraußenseite. When the outer ring is screwed into the water outlet, this sealing ring rests against an area in the interior of the water outlet in such a way that the sealing ring is pressed thereby. Since the sealing ring rests in the annular zone between the outer ring inner side and the ball zone outside or the Luftbeimischeraußenseite, a particularly simple and secure seal is achieved. Since the sealing ring in the annular zone between the outer ring inner side and the Kugelzonenaußenseite or the Luftbeimischeraußenseite pressed, at the same time the relative position between the Luftbeimischer and the outer ring against unintentional pivoting can be secured.

Der erfindungsgemäße Luftbeimischer ist aufgrund seiner Standard-Außenform, Standardaußenabmessungen und Standard-Außengewinde in jeden Standard-Wasserauslauf einschraubbar. Aufgrund dessen, dass der Luftbeimischer innerhalb der Kugel oder Kugelzone des Gelenkes liegt und keine zusätzlichen Befestigungsmittel unterhalb der Kugel erforderlich sind, wird eine besonders geringe Bauhöhe erreicht. Ferner besteht eine besonders einfache Konstruktion mit wenigen Bauteilen.The air blender according to the invention is due to its standard outer shape, standard outer dimensions and standard external thread can be screwed into any standard water outlet. Due to the fact that the air blender is within the ball or ball zone of the joint and no additional attachment means below the ball are required, a particularly low height is achieved. Furthermore, there is a particularly simple construction with few components.

Ist die Außenseite des Luftbeimischers teilkugelförmig ausgebildet und der Luftbeimischer mit dieser Außenseite im Außenring verschwenkbar gelagert, bildet der Luftbeimischer selbst das Innenteil des Kugelgelenkes, so dass der Luftbeimischer ohne Zwischenteil im Außenring gelagert werden kann. Dies führt zu einer besonders einfachen und preiswerten Konstruktion mit wenigen Teilen. Möglich ist aber auch, dass der Luftbeimischer zumindest teilweise innerhalb der Kugel eines Kugelgelenks gelagert ist, wobei die Kugel in dem Außenring gelagert ist, der im Auslaufende des Wasserauslaufs eingeschraubbar ist.If the outside of the air blender is formed in a part-spherical manner and the air blender is pivotably mounted with this outside in the outer ring, the air blender itself forms the inner part of the ball joint, so that the air blender can be stored without intermediate part in the outer ring. This leads to a particularly simple and inexpensive construction with few parts. But it is also possible that the air blender is at least partially mounted within the ball of a ball joint, wherein the ball is mounted in the outer ring, which is screwed into the outlet end of the water outlet.

Hierbei kann der ein Außengewinde aufweisender Außenring in seinen Außenabmessungen üblichen Luftbeimischern entsprechen. Von Vorteil ist dabei, wenn das Außengewinde des Luftbeimischers die Standardabmessungen M24 x 1 oder M28 x 1 aufweist.Here, the external thread exhibiting outer ring correspond in its outer dimensions usual air mixers. It is advantageous if the external thread of the air blender has the standard dimensions M24 x 1 or M28 x 1.

Vorzugsweise wird vorgeschlagen, dass die Kugel von einer Kugelzone gebildet ist. Auch ist von Vorteil, wenn die Kugel/Kugelzone von einem insbesondere zylindrischen Kanal durchdrungen ist, in dem der Luftbeimischer einliegt.It is preferably proposed that the ball is formed by a spherical zone. It is also advantageous if the ball / ball zone is penetrated by a particular cylindrical channel, in which the Luftbeimischer rests.

Auch ist von Vorteil, wenn an der Wasseraustrittseite an der Kugelzone ein zylindrischer, insbesondere buchsenförmiger Bereich angeformt ist. Hierbei kann die Kanalwand des Außenringes im Auslaufbereich nach außen sich erweitert, insbesondere konisch geformt sein, wobei an diesem sich erweiternden Kanalwandbereich der buchsenförmige Bereich der Kugel/Kugelzone beim Verschwenken zur Anlage gelangt.It is also advantageous if a cylindrical, in particular bush-shaped region is formed on the water outlet side at the spherical zone. Here, the channel wall of the outer ring in the outlet region widens outwards, be conically shaped in particular, wherein at this flared channel wall area of the sleeve-shaped area of the ball / ball zone comes to pivot during pivoting.

Ferner ist von Vorteil, wenn der Außenring mit einem Außengewinde in ein Innengewinde des vorderen Endes des Wasserauslaufes einschraubbar ist.It is also advantageous if the outer ring with an external thread in an internal thread of the front end of the water outlet can be screwed.

Vorzugsweise wird vorgeschlagen, dass der Luftbeimischer in den Kanal der Kugel/Kugelzone einschraubbar ist.It is preferably proposed that the air admixer can be screwed into the channel of the ball / ball zone.

Eine einfache Lagerung wird erreicht, wenn an der Außenseite des Luftbeimischers ein insbesondere zylindrischer oder teilzylindrischer Abschnitt vorsteht, der in einer entsprechend geformten Ausnehmung der Kugel bzw. des Außenringes als Lager einliegt.A simple storage is achieved when a particular cylindrical or partially cylindrical portion projects on the outside of the air blender, which rests in a correspondingly shaped recess of the ball or the outer ring as a bearing.

Das vordere Ende 1 eines Wasserauslaufes 2 einer Wasserarmatur, insbesondere eines Einhebelmischers besitzt eine Wasseraustrittsöffnung 3, in der ein Luftbeimischer 4 lösbar befestigt ist. Hierzu besitzt die zylindrische Austrittsöffnung 3 des Wasserauslaufes ein Innengewinde, in das ein Außenring 5 des Luftbeimischers mit seinem Außengewinde einschraubbar ist. Die Außenabmessungen des Luftbeimischers und damit des Außenringes 5 und auch die Abmessungen des Außengewindes sind Standard. Das Außengewinde hat hierbei die Größe M24 x 1 oder M28 x 1.The front end 1 of a water outlet 2 of a water fitting, in particular a single-lever mixer has a water outlet opening 3, in which an air mixer 4 is releasably attached. For this purpose, the cylindrical outlet opening 3 of the water outlet has an internal thread into which an outer ring 5 of the air blender with its external thread can be screwed. The outer dimensions of the Luftbeimischers and thus the outer ring 5 and the dimensions of the external thread are standard. The external thread has the size M24 x 1 or M28 x 1.

Im Innern des Außenringes 5 ist eine Kugel in Form einer Kugelzone 6 gelagert. Damit die Kugel bzw. die Kugelzone 6 im Außenring 5 sicher gehalten ist und nicht nach außen fallen kann, verjüngt sich der Durchmesser der Kanalwand 7 des Außenringes 5 nach außen hin um eine engste Stelle 8 zu bilden, von der aus der Kanalwand 7 sich nach außen hin konisch erweitert und damit dort eine konische Erweiterung 9 bildet. Vorzugsweise bildet die Innenseite des Außenringes 5 eine konkave Lagerung für die Kugel/Kugelzone 6.In the interior of the outer ring 5, a ball is mounted in the form of a spherical zone 6. Thus, the ball or the ball zone 6 is securely held in the outer ring 5 and can not fall outward, the diameter of the channel wall 7 of the outer ring 5 tapers outwardly to form a narrowest point 8, from which the channel wall 7 itself flared on the outside and thus there forms a conical extension 9. Preferably, the inside of the outer ring 5 forms a concave bearing for the ball / ball zone. 6

Die in der Kanalwand 7 drehverstellbar gelagerte Kugel bzw. Kugelzone 6 ist zum Wasserauslauf 2 hin durch einen koaxialen Dichtring 10 gehalten, der beim Einschrauben des Außenringes 5 in einen Spalt zwischen Außenring 5 und Kugel bzw. Kugelzone 6 dichtend dadurch gedrückt wird, dass beim Einschrauben die Oberseite des Dichtringes 10 gegen eine Stufe 11 des Wasserauslaufes zur Anlage gelangt. Damit erreicht der im Querschnitt dreieckförmige Dichtring 10 eine sichere Abdichtung zwischen Kugel und Außenring, so dass das Wasser durch den Luftbeimischer 4 hindurchströmt. Darüber hinaus erreicht die Anlage des Dichtringes 10 an der Stufe 11, dass auch kein Wasser zwischen Außenring und Austrittsöffnung 3 austreten kann.The rotatably mounted in the channel wall 7 ball or ball zone 6 is held to the water outlet 2 through a coaxial sealing ring 10 which is pressed sealingly when screwing the outer ring 5 in a gap between the outer ring 5 and ball or ball zone 6, that when screwing the top of the sealing ring 10 comes against a stage 11 of the water outlet to the plant. Thus, the cross-sectionally triangular sealing ring 10 reaches a secure seal between the ball and the outer ring, so that the water flows through the air admixer 4. In addition, the system of the sealing ring 10 reaches the stage 11 that no water between the outer ring and the outlet opening 3 can escape.

Die Kugel, bzw. Kugelzone 6 besitzt nach außen hin einen angeformten zylindrischen buchsenförmigen Bereich 12, der beim Verschwenken der Kugel/Kugelzone an die konische Erweiterung 9 zur Anlage gelangt, so dass damit der maximale Schwenkbereich der Kugel/Kugelzone bestimmt ist.The ball, or spherical zone 6 has outwardly an integrally formed cylindrical sleeve-shaped portion 12, the pivoting of the Ball / ball zone reaches the conical extension 9 to the plant, so that so that the maximum pivoting range of the ball / ball zone is determined.

Die erfindungsgemäße Konstruktion erreicht besonders geringe Außenabmessungen und insbesondere eine besonders geringe Bauhöhe, da die Bauteile alle ineinander liegen bzw. gesteckt und/oder geschraubt sind.The construction according to the invention achieves particularly small external dimensions and, in particular, a particularly low overall height, since the components are all in one another or plugged in and / or screwed.

Ein konstruktives Beispiel zeigen Fig. 3 und 4. Hier ist die Außenseite des Luftbeimischers 4 teilkugelförmig bzw. als Kugelzone ausgebildet und in dem Inneren des Außenringes 5 gelagert, ohne dass es eines Zwischenteils in Form der Kugel bzw. eines Kugelringes 6 bedarf. Als Lager sind an der Außenseite des Luftbeimischers 4 auf gegenüber liegenden Seiten zwei zylindrische bzw. teilzylindrische Vorsprünge 15 angeformt, die in entsprechenden Ausnehmungen 16 in der Innenseite des Außenringes 5 formschlüssig einliegen.
