Description

Die Erfindung geht aus von einem Brausekopf mit einem Brausekopfgehäuse und einer im Innern des Brausekopfgehäuses angeordneten Reinigungseinrichtung, mit deren Hilfe Zapfen in Strahlaustrittslöcher eingeschoben werden können.The invention is based on a shower head with a shower head housing and one inside the shower head housing arranged cleaning device, with the help of pins in Beam exit holes can be inserted.

Derartige Brauseköpfe mit Reinigungseinrichtungen gemäß dem Oberbegriff des Anspruchs 1 sind bekannt (DE-OS 37 07 885, DE-OS 44 28 788).Such shower heads with cleaning devices according to the preamble of claim 1 are known (DE-OS 37 07 885, DE-OS 44 28 788).

Bei den bekannten Brauseköpfen dieser Art wird entweder durch eine manuelle Betätigung, beispielsweise beim Umschalten von einer Strahlart zur anderen, oder durch das strömende Wasser angetrieben die Reinigungseinrichtung derart betätigt, daß die Stifte in die Strahlaustrittsöffnungen soweit eingeschoben werden, daß an den Rändern der Öffnung haftende Teilchen, insbesondere Verkalkungen, herausgeschoben werden.In the known shower heads of this type is either by a manual operation, for example when switching from one jet to another, or through the flowing water driven the cleaning device operated such that the pins are pushed into the beam outlet openings as far as possible particles sticking to the edges of the opening, especially calcifications, are pushed out.

Üblicherweise sind die Reinigungsstifte in ihrem Durchmesser etwas kleiner als die Strahlaustrittsöffnungen.The diameter of the cleaning pins is usually slightly smaller than the jet outlet openings.

Weiterhin bekannt sind Brauseköpfe mit Wasseraustrittsöffnungen, die Einsätze aus gummielastisch verformbarem Material aufweisen (DE 39 43 062 A1, DE 43 08 599 A1). Diese Einsätze ragen stromab aus der Strahlscheibe heraus und sollen entweder von Hand oder mit einer Einrichtung gewalkt, d.h. so verformt werden, daß sich Kalkablagerungen lösen. Bei der Verformung weicht die Innenöffnung von der geradlinigen unverformten Ausbildung ab.Shower heads with water outlet openings are also known, the inserts made of elastically deformable material have (DE 39 43 062 A1, DE 43 08 599 A1). These missions protrude downstream from the spray disc and should either tumbled by hand or with a device, i.e. so be deformed so that limescale deposits loosen. In the Deformation deviates the inner opening from the straight line undeformed training.

Der Erfindung liegt die Aufgabe zugrunde, einen Brausekopf zu schaffen, der bei einfachem Aufbau die Möglichkeit der leichten und einfachen Reinigung der Strahlaustrittsöffnungen von Ablagerungen oder sonstigen Verschmutzungen bietet.The invention has for its object to a shower head create the possibility of simple construction easy and simple cleaning of the jet outlet openings of deposits or other dirt.

Zur Lösung dieser Aufgabe schlägt die Erfindung einen Brausekopf mit den im Anspruch 1 genannten Merkmalen vor. Weiterbildungen der Erfindung sind Gegenstand von Unteransprüchen.To achieve this object, the invention proposes a shower head with the features mentioned in claim 1. further developments the invention are the subject of dependent claims.

Das Vorsehen von gummielastisch verformbaren Einsätzen hat den Vorteil, daß die Stifte eine bessere Reinigungsfunktion durchführen können. Beispielsweise können Ablagerungen im Brausewasser, beispielsweise Sandkörner, auch dann durch die Brauseeinrichtung entfernt werden, wenn diese etwas größer sind als die Innenöffnung der Einsätze. Die Einsätze können hier etwas nachgeben. Auch die Kalkablagerungen lassen sich leichter durch die Reinigungsstifte lösen, da auch hier eine Verformung der Einsätze auftreten kann, was dann zu einem Abplatzen von Kalkablagerungen führen kann, die sich nicht verformen lassen.The provision of elastically deformable inserts has the advantage that the pens have a better cleaning function can perform. For example, deposits in the Shower water, for example grains of sand, also through the Shower equipment can be removed if it is slightly larger are as the inner opening of the inserts. The stakes can give in here. The limescale deposits can also be removed easier to loosen with the cleaning pens, as here too Deformation of the inserts can occur, which then leads to a Chipping from limescale can result, which cannot deformed.

Insbesondere kann in Weiterbildung der Erfindung vorgesehen sein, daß die Elastomereinsätze über die Außenseite der Strahlscheibe vorstehen. In diesem Fall braucht der Benutzer nur mit einer leichten Handbewegung über die Strahlscheibe zu streichen, um die Einsätze etwas zu verformen, wodurch ebenfalls ein Lösen von Ablagerungen erfolgen kann. Er hat also die Möglichkeit, mit Hilfe zweier sich gegenseitig ergänzender Maßnahmen eine Reinigung der Strahlaustrittsöffnungen durchzuführen. Gerade durch die Verformbarkeit der Einsätze, die auch das Ablösen von dünnen Ablagerungen längs der Öffnungswandungen ermöglicht, wird auch für ein sauberes Strahlbild gesorgt.In particular, can be provided in a further development of the invention be that the elastomer inserts over the outside of the Protrude jet disc. In this case the user needs only with a slight hand movement over the spray disc swipe to slightly deform the inserts, causing deposits can also be loosened. He has so the opportunity to help each other with the help of two Additional measures include cleaning the beam outlet openings perform. Precisely because of the deformability of the Inserts that also detach thin deposits lengthways The opening walls allows for a clean one Beam pattern taken care of.

In Weiterbildung der Erfindung kann vorgesehen sein, daß die Außenseite der Einsätze, d. h. die Enden der aus der Strahlscheibe vorspringenden Einsätze, parallel zu der Außenseite der Strahlscheibe verlaufen. Dies ergibt insbesondere bei gewölbten Strahlscheiben einen günstigeren optischen Eindruck und ermöglicht auch das Ablösen von Verunreinigungen unabhängig von der Richtung, in der der Benutzer über die Oberfläche streicht.In a further development of the invention it can be provided that the Outside of the inserts, d. H. the ends of the jet disc protruding inserts, parallel to the outside the spray disc. This is particularly the case with curved jet disks give a more favorable visual impression and also allows contaminants to be removed independently from the direction in which the user is across the surface sweeps.

In Weiterbildung der Erfindung kann vorgesehen sein, daß die Reinigungsstifte einen dem Innendurchmesser der Strahlaustrittsöffnung entsprechenden, gegebenenfalls etwas größeren Außendurchmesser aufweisen.In a further development of the invention it can be provided that the Cleaning pens have the inside diameter of the jet outlet opening corresponding, if necessary somewhat larger Have outside diameter.

Der Außendurchmesser der Stifte kann größer sein als der Innendurchmesser der Öffnungen der Einsätze, da die Einsätze ja nachgeben können. Aufgrund der Nachgiebigkeit ist es aber auch möglich, die Stifte beispielsweise nicht exakt auszurichten, so daß sie exzentrisch zu den Öffnungen angeordnet werden können.The outside diameter of the pins can be larger than that Inner diameter of the openings of the inserts since the inserts can give in yes. Because of the flexibility, it is also possible not to align the pins exactly, for example, so that they are arranged eccentrically to the openings can be.

Auch ein leichtes Schrägverlaufen der Reinigungsstifte gegenüber der Achse der Austrittsöffnungen ist möglich, insbesondere dann, wenn die Austrittsöffnungen nur einen relativ kurzen die eigentliche Austrittsöffnung bildenden zylindrischen Bereich aufweisen. Also a slight inclination of the cleaning pins relative to the axis of the outlet openings is possible especially if the outlet openings only one relatively short forming the actual outlet opening have cylindrical region.

Dieser zylindrische Bereich ist mit Vorteil im äußeren Bereich der Einsätze angeordnet.This cylindrical area is advantageous in the outer Area of the inserts arranged.

Insbesondere kann in Weiterbildung vorgesehen sein, daß die Einsätze mehrerer Öffnungen, insbesondere alle Einsätze, zu einem an der Innenseite der Strahlscheibe insbesondere flächig anliegenden Bauteil zusammengefaßt sind. Dieses Bauteil läßt sich sehr einfach montieren, da es nur von der Rückseite der Strahlscheibe eingelegt und eingedrückt zu werden braucht. Die Festlegung der Einsätze kann dadurch geschehen, daß diese in den Öffnungen der Strahlscheibe kraft- und/oder formschlüssig festlegbar sind.In particular, it can be provided in further training that the Inserts of several openings, in particular all inserts, too one on the inside of the spray disc in particular Comprehensive component are summarized. This Component can be assembled very easily, since it is only from the Back of the spray disc inserted and pressed in are needed. This allows the stakes to be set happen that this in the openings of the spray disc are positively and / or positively fixed.

Das Bauteil kann praktisch in die Strahlscheibe eingeknöpft werden.The component can be practically buttoned into the spray disc become.

Die Betätigungseinrichtung zum Einschieben der Reinigungsstifte in die Strahlaustrittsöffnungen kann beispielsweise manuell betätigbar sein, indem ein Benutzer an einer Handhabe angreift und die Reinigungseinrichtung betätigt.The actuator for inserting the cleaning pins into the beam outlet openings, for example be manually operable by a user on a handle attacks and actuated the cleaning device.

Eine weitere Möglichkeit besteht darin, daß die Reinigungseinrichtung immer dann betätigt wird, wenn der Brausekopf von einer Strahlart in eine andere Strahlart umgeschaltet wird.Another possibility is that the cleaning device is actuated whenever the shower head by one jet type is switched to another jet type.

Unter Betätigen der Reinigungseinrichtung ist hier zu verstehen, daß die Stifte in die Strahlaustrittsöffnungen eingeschoben und anschließend wieder herausgezogen werden.Operating the cleaning device here means that the pins are inserted into the beam exit openings and then pulled out again.

Eine weitere Möglichkeit besteht darin, daß die Reinigungseinrichtung von einer Turbine hin- und hergehend angetrieben wird, die von dem durch den Brausekopf strömenden Wasser angetrieben wird. Another possibility is that the cleaning device driven back and forth by a turbine from the water flowing through the shower head is driven.

Einzelheiten solcher Betätigungseinrichtungen sind aus den beiden eingangs genannten Veröffentlichungen bekannt, deren Einzelheiten hiermit-durch Bezugnahme zum Inhalt der vorliegenden Beschreibung gemacht werden.Details of such actuators are from the known two publications mentioned, whose Details hereby - by reference to the content of the present Description.

Weitere Merkmale, Einzelheiten und Vorzüge ergeben sich aus den Patentansprüchen, deren Wortlaut durch Bezugnahme zum Inhalt der Beschreibung gemacht wird, der folgenden Beschreibung einer bevorzugten Ausführungsform der Erfindung sowie anhand der Zeichnung. Hierbei zeigt die einzige Zeichnungsfigur einen Schnitt durch einen Brausekopf am Beispiel einer Handbrause.Further characteristics, details and advantages result from the claims, the wording of which by reference to Content of the description is made of the following description a preferred embodiment of the invention as well based on the drawing. Here shows the only drawing figure a section through a shower head using the example of a Hand shower.

Das vordere Ende der Handbrause bildet ein Brausekopfgehäuse 1, das eine im wesentlichen kreisförmige Öffnung bildet. Durch diese Öffnung ist in das Innere des Gehäuses ein Kern 2 eingesetzt und in dem Gehäuse befestigt. Der Brausekopfkern 2 enthält mit dem Gehäuse zusammenwirkende Wasserführungen, von denen eine zu einer mittleren Gruppe von Strahlenaustrittsöffnungen mit einer Belüftungseinrichtung 3 führt.The front end of the hand shower forms a shower head housing 1, which forms a substantially circular opening. A core 2 is through this opening into the interior of the housing inserted and fastened in the housing. The shower head core 2 contains water channels that interact with the housing, from one to a middle group of radiation exit openings leads with a ventilation device 3.

In den Kern 2 des Brausekopfgehäuses und den Rand der Öffnung ist eine Strahlscheibe 4 eingesetzt, beispielsweise eingeschnappt. Diese Strahlscheibe 4 weist eine konvex gekrümmte Außenseite 5 auf. An der Innenseite enthält die Strahlscheibe 4 eine kurzzylindrische äußere Schürze 6, an deren Außenseite eine umlaufende Rippe 7 angeformt ist. Mit dieser Rippe 7 greift die Strahlscheibe hinter den Rand der Öffnung des Brausekopfgehäuses.In the core 2 of the shower head housing and the edge of the opening a spray disc 4 is inserted, for example snapped. This jet disc 4 has a convex curvature Outside 5 on. Contains the spray disc on the inside 4 a short cylindrical outer apron 6, on the outside a circumferential rib 7 is formed. With this rib 7 grabs the spray disc behind the edge of the opening of the Showerhead housing.

Koaxial zu der Schürze 6 enthält die Strahlscheibe 4 einen weiter innen liegenden zylindrischen Ansatz 8, der mit seiner Außenseite an einer entsprechend geformten zylindrischen Wandfläche des Kerns 2 anliegt. Coaxial to the apron 6, the jet disc 4 contains one inner cylindrical approach 8, with its Outside on a correspondingly shaped cylindrical Wall surface of the core 2 is applied.

Innerhalb des Ansatzes 8 ist in die Strahlscheibe 4 eine die Belüftungseinrichtung enthaltende Einheit eingesetzt und mit Hilfe eines Dichtrings 9 abgedichtet.Within the approach 8 is a in the spray disc 4 Ventilation unit containing inserted and with Sealed with the help of a sealing ring 9.

Zum Verdrehen der Strahlscheibe 4 gegenüber dem Kern 2 des Brausekopfs ist ein Griffelement 9 vorgesehen, an dem ein Benutzer angreifen kann.To rotate the jet disc 4 relative to the core 2 of the Shower head, a handle element 9 is provided, on which a Can attack users.

Die Strahlscheibe 4 enthält in dem Ringbereich zwischen der äußeren Schürze 6 und dem inneren zylindrischen Ansatz 8 zwei konzentrisch angeordnete Reihen von Öffnungen. Jede Öffnung wird durch einen Einsatz 11 ausgefüllt, er aus gummielastischem Material besteht und eine durchgehende Innenöffnung 12 aufweist. Alle Einsätze 11 sind an der Vorderseite eines flachen Rings 13 angeformt, dessen Breite etwa dem radialen Innenabstand zwischen der Schürze 6 und dem Ansatz 8 entspricht.The jet disc 4 contains in the ring area between the outer apron 6 and the inner cylindrical neck 8 two concentrically arranged rows of openings. Every opening is filled in by an insert 11, it made of rubber-elastic Material consists and a continuous inner opening 12th having. All inserts 11 are on the front of one formed flat ring 13, the width of which is approximately the radial Internal distance between the apron 6 and the approach 8 corresponds.

Die Ansätze weisen an ihrer Außenseite einen Hinterschnitt auf, mit dem sie hinter eine Schulter der Öffnung der Strahlscheibe 4 greifen. Die Innenöffnung 12 der Einsätze 11 ist so geformt, daß sie auf der in das Innere des Brausekopfs gerichteten Seite einen größeren Durchmesser aufweisen, der sich dann trichterförmig auf einen zylindrischen Bereich kleineren Durchmessers verjüngt.The approaches have an undercut on the outside with which she is behind a shoulder opening the jet disc 4 grab. The inner opening 12 of the inserts 11 is like this shaped that they are on the inside of the shower head facing side have a larger diameter, the then funnel-shaped onto a cylindrical area smaller diameter tapers.

An der Außenseite 5 der Strahlscheibe 4 verlaufen die Enden der Einsätze 11 parallel zu dieser Außenseite 5. Die Einsätze 11 stehen also überall gegenüber der Außenseite 5 der Strahlscheibe 4 um etwa den gleichen Abstand vor. Die Innenöffnungen aller Einsätze verlaufen parallel zueinander und zu der Drehachse der Strahlscheibe 4. On the outside 5 of the jet disc 4, the ends of the Inserts 11 parallel to this outside 5. The inserts 11 are thus everywhere opposite the outside 5 of the spray disc 4 by about the same distance. The inside openings all inserts run parallel to each other and to the Axis of rotation of the spray disc 4.

Zwischen der äußeren Schürze 6 und dem inneren zylindrischen Ansatz 8 ist in den dort gebildeten Raum der Strahlscheibe 4 eine Reinigungseinrichtung 10 angeordnet, die ein starres Ringelement 14 enthält. Das Ringelement 14 ist gegenüber der Strahlscheibe 4 axial verschiebbar, aber nicht verdrehbar gelagert. Zu diesem Zweck weist die äußere Schürze 6 der Strahlscheibe 4 an ihrer Innenseite einen Vorsprung 15 auf, der in eine entsprechende Ausnehmung der radialen Außenseite des Ringelements 14 eingreift.Between the outer skirt 6 and the inner cylindrical Approach 8 is in the space of the jet disc 4 formed there a cleaning device 10 is arranged, the rigid Contains ring element 14. The ring element 14 is opposite to the Jet disc 4 axially displaceable, but not rotatable stored. For this purpose, the outer apron 6 of the Spray disc 4 on its inside a projection 15, in a corresponding recess on the radial outside of the ring element 14 engages.

Das Ringelement 14 weist an seiner radialen Innenseite zwei einander diametral gegenüberliegende Vorsprünge 16 auf, die in eine Nut in der Zylindermantelaußenseite des Kerns 2 eingreifen. Links in der Zeichnungsfigur ist das Ringelement 14 in einer anderen Stellung gezeichnet als rechts in der Figur. Die Nut 17 in der Außenseite des Kerns verläuft längs der Außenseite leicht zickzackförmig.The ring element 14 has two on its radial inside diametrically opposite projections 16 on the into a groove in the outside of the cylinder jacket of the core 2 intervention. The ring element is on the left in the drawing figure 14 drawn in a different position than on the right in the Figure. The groove 17 in the outside of the core runs longitudinally the outside is slightly zigzag.

Wird die Strahlscheibe gegenüber dem Kern 2 verdreht, so dreht sich das Ringelement 14 mit. Der in die Nut 17 eingreifende Vorsprung 16 folgt der Form der Nut und führt daher zu einer Verschiebung des Ringelements zwischen einer Stellung, in der er näher an die Strahlscheibe 4 herangerückt ist, und einer Stellung, in der er einen maximalen Abstand von der Strahlscheibe 4 aufweist.If the jet disc is rotated relative to the core 2, so the ring element 14 also rotates. The engaging in the groove 17 Projection 16 follows the shape of the groove and therefore leads to a displacement of the ring element between a position, in which he has moved closer to the spray disc 4, and a position in which it is at a maximum distance from the Jet disc 4 has.

Auf der der Strahlscheibe 4 zugewandten Vorderseite des Ringelements 14 sind zwei koaxiale Reihen von Reinigungsstiften 18 angeformt, die in ungefährer axialer Ausrichtung gegenüber den Innenöffnungen 12 der Einsätze 11 angeordnet sind. Durch Verschieben des Ringelements 14, hervorgerufen durch eine Verdrehung der Strahlscheibe 4, werden diese Reinigungsstifte 18 in die Innenöffnungen 12 der Einsätze 11 eingeschoben. Das Einschieben geht soweit, siehe links in der Figur, daß die freien Enden der Reinigungsstifte 18 aus den Innenöffnungen der Einsätze 11 heraustreten.On the front of the jet disc 4 facing the Ring element 14 are two coaxial rows of cleaning pins 18 integrally formed, which is in approximately axial alignment arranged opposite the inner openings 12 of the inserts 11 are. By moving the ring element 14, caused by rotating the jet disc 4, they become Cleaning pins 18 in the inner openings 12 of the inserts 11 inserted. The insertion goes as far, see left in the Figure that the free ends of the cleaning pins 18 from the Step out the inner openings of the inserts 11.

Im gegenüberliegenden Fall, rechts in der Figur, sind die vorderen Ende der Reinigungsstifte 18 in den erweiterten Teilen der Innenöffnungen 12 angeordnet. Sie leiten daher das Wasser zwischen sich und dem Rand der Öffnung durch die Innenöffnungen 12 hindurch.In the opposite case, on the right in the figure, are front end of the cleaning pins 18 in the extended Parts of the inner openings 12 arranged. So you run it Water between itself and the edge of the opening through the Inner openings 12 through.

Der Durchmesser der Reinigungsstifte 12 in ihrem vorderen aktiven Bereich kann dem Innendurchmesser der Innenöffnungen 12 in deren engerem Bereich gleich sein, oder auch etwas größer. Aufgrund der Herstellung der Einsätze 11 und des Ringelements 13 aus gummielastisch verformbarem Elastomermaterial kann das Material, falls erforderlich, etwas ausweichen.The diameter of the cleaning pins 12 in their front active area can be the inner diameter of the inner openings 12 be the same in their narrow range, or something greater. Due to the manufacture of the inserts 11 and Ring element 13 made of elastically deformable elastomer material If necessary, the material can dodge a little.

Durch Betätigen der Reinigungseinrichtung können die Strahlaustrittsöffnungen der Einsätze 11 von Ablagerungen, Schmutz o. dgl. gereinigt werden.By actuating the cleaning device, the jet outlet openings can of the inserts 11 of deposits, dirt or the like can be cleaned.

Während bei der dargestellten Ausführungsform die Reinigungseinrichtung 10 immer dann betätigt wird, wenn der Benutzer die Strahlscheibe 4 verdreht, ist es ebenfalls möglich, die Reinigungseinrichtung 10 von einer Turbine hin- und hergehend bewegen zu lassen, die von dem durch den Brausekopf fließenden Wasser angetrieben wird.While in the illustrated embodiment, the cleaning device 10 is actuated whenever the user the jet disc 4 rotated, it is also possible that Cleaning device 10 back and forth from a turbine let it move, that of the flowing through the shower head Water is driven.
