Description

Die Erfindung geht aus von einer Brause mit einem Brausekopf, einer Strahlscheibe und einer Reinigungseinrichtung.The invention is based on a shower head with a shower head, a spray disc and a cleaning device.

Es ist bereits eine Brause bekannt (DE-PS 38 04 089), bei der innerhalb des Brausekopfs eine Platte angeordnet ist, die auf ihrer der Strahlscheibe zugewandten Seite eine der Zahl der Strahlaustrittsöffnungen entsprechende Zahl von Stiften aufweist. Mit Hilfe eines durch die Außenwand des Brausekopfs geführten Schiebers läßt sich die Scheibe nach vorne schieben, so daß die Stifte in die Strahlaustrittsöffnungen gelangen und dort ggf. vorhandene Kalkablagerungen oder sonstige Verschmutzungen nach außen durchstoßen. Diese Brause benötigt zum Durchführen der Reinigung einen bewußten Vorgang.A shower is already known (DE-PS 38 04 089), in which a plate is arranged inside the shower head and has a number of pins corresponding to the number of jet outlet openings on its side facing the jet disk. With the help of a slide led through the outer wall of the shower head, the pane can be pushed forward so that the pins get into the jet outlet openings and, if necessary, penetrate existing limescale deposits or other contaminants to the outside. This shower requires a conscious process to perform the cleaning.

Bei einer ähnlichen Brause (US-PS 19 82 538) ist zur Betätigung einer Reinigungseinrichtung ein Drehgriff an der Seite des Brausekopfs vorgesehen.In a similar shower (US-PS 19 82 538) a rotary handle is provided on the side of the shower head for actuating a cleaning device.

Weiterhin ist ein Brausekopf bekannt (EP-B-284 801), bei dem eine Stifte zum Durchstoßen der Strahlaustrittsöffnungen aufweisende Reinigungseinrichtung immer dann betätigt wird, wenn zwischen zwei verschiedenen Strahlarten der Brause umgeschaltet wird. Hier ist also kein bewußtes Betätigen der Reinigungseinrichtung mehr erforderlich.Furthermore, a shower head is known (EP-B-284 801) in which a cleaning device having pins for piercing the jet outlet openings is actuated whenever the shower is switched between two different types of jet. So there is no longer any need to consciously operate the cleaning device.

Der Erfindung liegt die Aufgabe zugrunde, eine Brause zu schaffen, die eine automatische Reinigung der Strahlaustrittsöffnungen sowie weitere Vorteile aufweist.The invention has for its object to provide a shower head that has an automatic cleaning of the jet outlet openings and other advantages.

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

Durch den durch das strömende Wasser angetriebenen Antrieb für die Reinigungseinrichtung wird diese immer betätigt, sobald die Brause benutzt wird. Es ist möglich, durch eine entsprechende Untersetzung dafür zu sorgen, daß der Wasserdruck ausreicht, die Reinigungseinrichtung zu betätigen. Durch das periodische Verschließen und Wiederöffnen der Strahlaustrittsöffnungen, auch wenn die Öffnungen nicht vollständig geschlossen werden, wird zusätzlich noch ein Massageeffekt bewirkt und dafür gesorgt, daß der Wasserverbrauch gegenüber einer Brause mit gleich großen Strahlaustrittsöffnungen verringert wird.The drive for the cleaning device, which is driven by the flowing water, is always actuated as soon as the shower is used. It is possible to ensure that the water pressure is sufficient to operate the cleaning device by means of a corresponding reduction. The periodic closing and reopening of the jet outlet openings, even if the openings are not completely closed, additionally causes a massage effect and ensures that the water consumption is reduced compared to a shower with the same size jet outlet openings.

Es kann vorgesehen sein, daß alle Stifte gleichzeitig an der gleichen axialen Position angeordnet sind und dadurch gleichzeitig bewegt werden. Es ist aber ebenfalls möglich, daß die Stifte zu Gruppen zusammengefaßt sind, wobei die Gruppen dann von dem Antrieb antreibbar sind. Es kann vorgesehen sein, daß die Stifte mindestens zweier Gruppen in mindestens einer Stellung des Antriebs eine unterschiedliche Position aufweisen. Auf diese Weise läßt sich eine Massagewirkung erreichen, die vom Benutzer stärker oder besser wahrgenommen wird. Zusätzlich kann auf diese Weise dafür gesorgt werden, daß in keiner Stellung des Antriebs alle Strahlaustrittsöffnungen verschlossen sind.It can be provided that all pins are arranged in the same axial position at the same time and are thereby moved simultaneously. However, it is also possible for the pins to be combined into groups, the groups then being able to be driven by the drive. It can be provided that the pins of at least two groups have a different position in at least one position of the drive. In this way, a massage effect can be achieved that the user perceives more or better. In addition, it can be ensured in this way that all jet outlet openings are not closed in any position of the drive.

Erfindungsgemäß kann vorgesehen sein, daß die Stifte längs mindestens eines Kreises angeordnet sind. Die Stifte können innerhalb des Brausekopfs an einem Ringelement oder an Teilringelementen befestigt sein, beispielsweise angespritzt, wobei sich eine Kreisform für einen Antrieb besonders eignet.According to the invention it can be provided that the pins are arranged along at least one circle. The pins can be fastened within the shower head to a ring element or to partial ring elements, for example injection molded, a circular shape being particularly suitable for a drive.

Zum Verschieben der Stifte kann vorgesehen sein, daß der Antrieb eine rotierende Kurvenführung für die Stifte aufweist. Beispielsweise können die Stifte bzw. die Elemente, an denen die Stifte befestigt sind, mit einem Zapfen in eine Nut der rotierenden Kurvenführung eingreifen, wobei die Drehung der rotierenden Kurvenführung dann zu der Axialverschiebung der Stifte führt. Dabei lassen sich vielfältige Bewegungsabläufe verwirklichen.To move the pins, it can be provided that the drive has a rotating cam guide for the pins. For example, the pins or the elements to which the pins are fastened can engage with a pin in a groove of the rotating cam guide, the rotation of the rotating cam guide then leading to the axial displacement of the pins. Various movements can be realized.

Insbesondere kann vorgesehen sein, daß die Kurvenführung eine Verzahnung aufweist, mit der eine von dem Wasser angetriebene Turbine in Wirkverbindung steht.In particular, it can be provided that the curve guide has a toothing with which a turbine driven by the water is operatively connected.

Erfindungsgemäß kann vorgesehen sein, daß von mehreren Gruppen von Stiften jeweils nur die Stifte einer Gruppe in den Strahlaustrittsöffnungen angeordnet sind. Bei kalkhaltigem Wasser und längerem Nichtgebrauch der Brause kann dafür gesorgt werden, daß trotz eines leichten Festbackens der Stifte die von dem Antrieb bewirkte Kraft noch zum Lösen der Reinigungseinrichtung ausreicht.According to the invention it can be provided that of several groups of pins only the pins of one group are arranged in the beam outlet openings. If the shower contains chalky water and if the shower is not used for a long time, it can be ensured that despite a slight sticking of the pins, the force caused by the drive is still sufficient to release the cleaning device.

Erfindungsgemäß kann in nochmaliger Weiterbildung vorgesehen sein, daß bei abgeschalteter Wasserzufuhr alle Stifte aus den Strahlaustrittsöffnungen ausgerückt werden. Dies kann durch einen durch Federwirkung betätigbaren Hubantrieb bewirkt werden. Die Federkraft wird bei eingeschalteter Wasserzufuhr durch den Wasserdruck überwunden.According to the invention, it can be provided in a further development that, when the water supply is switched off, all the pins are disengaged from the jet outlet openings. This can be effected by a lifting drive which can be actuated by spring action. The spring force is overcome by the water pressure when the water supply is switched on.

Erfindungsgemäß kann vorgesehen sein, daß die Gruppen sich über je einen Kreisbogen erstrecken, und benachbarte Gruppen unterschiedliche axiale Positionen der Stifte einnehmen. Auf diese Weise kann die Massagewirkung längs der Kreisbögen wandern.According to the invention, it can be provided that the groups each extend over an arc, and neighboring groups assume different axial positions of the pins. In this way, the massage effect can move along the arcs.

Es ist jedoch ebenfalls bzw. gleichzeitig auch möglich, daß die Stifte längs mindestens zweier konzentrischer Kreise angeordnet sind. Auch hier können die Stifte zweier benachbarter Kreise unterschiedlich positioniert sein, so daß eine von innen nach außen und zurück bewegte Massagewirkung erreicht wird. Selbstverständlich sind auch mit Vorteil Kombinationen dieser beiden Bewegungen möglich.However, it is also possible at the same time that the pins are arranged along at least two concentric circles. Here, too, the pins of two adjacent circles can be positioned differently, so that a massage effect moved from the inside out and back is achieved. Of course, combinations of these two movements are also advantageously possible.

Normalerweise wird die ständige Reinigung und ggf. die Massagewirkung durch den Antrieb durch die Wasserströmung bewirkt. Ist aber die Brause längere Zeit nicht in Betrieb, beispielsweise während einer längeren Abwesenheit, so besteht die Möglichkeit, daß eine Kalkablagerung zwischen den Stiften und den Strahlaustrittsöffnungen die Reinigungseinrichtung so schwergängig macht, daß sie beim normalen Brausebetrieb nicht wieder anläuft. Hier kann nun vor oder während des Brausens durch ein Betätigen der manuellen Einrichtung dieses Anhaften oder die Schwergängigkeit überwunden werden. Durch manuellen Eingriff steht eine größere Kraft zur Verfügung, als sie durch den Wasserdruck allein herstellbar wäre. Sobald die Reinigungseinrichtung wieder gelöst und die Schwergängigkeit überwunden ist, kann dann wieder die wasserbetätigte Reinigungseinrichtung einsetzen.Normally, the constant cleaning and possibly the massage effect is caused by the drive through the water flow. However, if the shower is not in operation for a long time, for example during a long absence, there is the possibility that limescale deposits between the pins and the jet outlet openings make the cleaning device so stiff that it does not start again during normal shower operation. Here, before or during the shower, this attachment or the stiffness can be overcome by actuating the manual device. By manual intervention, a greater force is available than would be produced by the water pressure alone. As soon as the cleaning device is loosened again and the stiffness is overcome, the water-operated cleaning device can then be used again.

Insbesondere kann vorgesehen sein, daß die manuelle Betätigungseinrichtung durch Angriff des Benutzers, beispielsweise durch Verdrehen der Strahlscheibe, betätigt wird.In particular, it can be provided that the manual actuating device is actuated by attack by the user, for example by turning the jet disc.

Wenn der strömungsbetätigte Antrieb besonders leichtgängig ist, so besteht die Gefahr, daß bei Betätigung der manuellen Löseinrichtung sich der Antrieb zurückdreht. Um dies zu verhindern, kann in Weiterbildung eine Sperre zur Verhinderung einer solchen Rückwärtsbewegung vorgesehen sein.If the flow-actuated drive is particularly smooth, there is a risk that the drive will turn back when the manual release device is actuated. In order to prevent this, in a further development a lock can be provided to prevent such a backward movement.

Eine solche Sperre kann insbesondere zwischen einem rotierenden Teil und einem sich nicht mitdrehenden Teil der Brause angeordnet sein.Such a lock can in particular be arranged between a rotating part and a non-rotating part of the shower.

Erfindungsgemäß kann die Sperre mindestens eine an dem einen Brausekopfteil angeordnete, insbesondere angeformte federnde Zunge aufweisen, die an dem anderen Brausekopfteil federnd anliegt, das mindestens eine quer zur Drehrichtung verlaufende Anlageschulter aufweist. Bei der normalen Drehung gleitet die federnde Zunge über das jeweils andere Teil ab, und nur bei Drehung in umgekehrter Drehrichtung erfolgt eine Sperrung der Einrichtung. Dies bedeutet, daß die manuelle Betätigungseinrichtung dann nur durch Verdrehen beispielsweise der Strahlscheibe in einer Drehrichtung betätigt wird.According to the invention, the lock can have at least one resilient tongue arranged on the one shower head part, in particular molded on, which rests resiliently on the other shower head part, which has at least one contact shoulder extending transversely to the direction of rotation. During normal rotation, the resilient tongue slides over the other part, and the device is only locked when rotating in the opposite direction of rotation. This means that the manual actuating device is then actuated only by rotating the jet disc in one direction of rotation, for example.

Erfindungsgemäß kann vorgesehen sein, daß die Anlageschulter von dem Ende einer in Drehrichtung keilförmigen Tasche in einem der beiden Brausekopfteile gebildet wird. Diese Tasche kann so ausgebildet werden, daß bei Durchführung der Sperrung die federnde Zunge seitlich mit geringem Spiel umgeben wird, so daß sie nicht seitlich ausweichen und auch nicht abbrechen kann.According to the invention it can be provided that the contact shoulder is formed by the end of a pocket which is wedge-shaped in the direction of rotation in one of the two shower head parts. This pocket can be designed so that when the lock is carried out, the resilient tongue is surrounded on the side with little play, so that it cannot move sideways and also cannot break off.

Zum Verschieben der Stifte kann Antrieb eine rotierende Kurvenführung für die Stifte aufweisen. In diesem Fall ist vorzugsweise die Sperre zwischen dieser Kurvenführung und einem Brausekopfteil vorgesehen, insbesondere einer Verteilerscheibe.To move the pins, the drive can have a rotating cam guide for the pins. In this case, the barrier between this curve and is preferably provided a shower head part, in particular a distributor disc.

Der in Fig. 1 dargestellte Brausekopf einer Handbrause ist am Ende eines hohlen Griffs 1 angeordnet. Durch den hohlen Griff 1 gelangt das Wasser in den Brausekopf. An der in Fig.1 unteren Seite ist an dem Brausekopf eine Strahlaustrittsscheibe 2 mit Hilfe einer zentralen Schraube 3 befestigt. Die Schraube 3 greift mit ihrem Gewinde 4 in eine mit einem Innengewinde versehene im Brausekopf ausgebildete Buchse 5 ein. Die Strahlaustrittsscheibe 2 ist längs ihres Umfangs gegenüber dem Brausekopfgehäuse mit Hilfe einer Dichtung 6 abgedichtet.The shower head of a hand shower shown in FIG. 1 is arranged at the end of a hollow handle 1. Through the hollow handle 1, the water gets into the shower head. A jet outlet disk 2 is fastened to the shower head on the lower side in FIG. 1 by means of a central screw 3. The screw 3 engages with its thread 4 in a socket 5 provided with an internal thread in the shower head. The jet exit disk 2 is sealed along its circumference with respect to the shower head housing by means of a seal 6.

Die Strahlaustrittsscheibe 2 enthält drei sich längs dreier konzentrischer Kreise erstreckende Reihen von Strahlaustrittsöffnungen 7.The jet outlet disk 2 contains three rows of jet outlet openings 7 extending along three concentric circles.

Die Strahlscheibe 2 weist eine zylindrische in das Innere des Brausekopfs gerichtete Schürze 8 auf. Die Innenseite 9 der Schürze 8 bildet eine Zylinderfläche.The spray disc 2 has a cylindrical skirt 8 directed into the interior of the shower head. The inside 9 of the apron 8 forms a cylindrical surface.

An dieser Zylinderfläche 9 liegen mit ihren Außenflächen insgesamt acht Segmente 10 an, die sich in Umfangsrichtung jeweils über einen Achtelkreis erstrecken. Die untereinander identisch ausgebildeten Segmente sind in ihrer Umfangsposition durch nach innen gerichtete, etwa halbkreisförmige Vorsprünge 11 an der Innenwand 9 der Schürze 8 der Strahlscheibe 2 festgelegt. Die Segmente 10 können in Richtung senkrecht zur Strahlscheibe 2, d.h. in Axialrichtung längs der Zylinderfläche 9, gleiten. Sie enthalten auf ihrer der Strahlscheibe 2 zugewandten Seite einzelne Stifte 12. Die Stifte 12 sind in axialer Verlängerung der Strahlaustrittsöffnung 7 angeordnet. Jeder Strahlaustrittsöffnung 7 ist ein Stift 12 an einem Segment 10 zugeordnet.A total of eight segments 10 abut this cylindrical surface 9 with their outer surfaces, each of which extends in the circumferential direction over an eighth circle. The segments, which are identical to one another, are fixed in their circumferential position by inwardly directed, approximately semicircular projections 11 on the inner wall 9 of the apron 8 of the jet disc 2. The segments 10 can slide in the direction perpendicular to the jet disk 2, ie in the axial direction along the cylinder surface 9. They contain individual pins 12 on their side facing the jet disk 2. The pins 12 are arranged in an axial extension of the jet outlet opening 7. A pin 12 on a segment 10 is assigned to each beam outlet opening 7.

An der Strahlscheibe 2 ist auf ihrer in das Innere des Brausekopfs gerichteten Seite eine ebene Scheibe 13 befestigt, die senkrecht auf der Rotationsachse der Schraube 3 steht. An der Scheibe 13 ist ein Ringelement 14 drehbar gehaltert, das sich also um die Schraube 3 herum verdrehen kann. Das Ringelement 14 weist auf seiner Innenseite eine Verzahnung 15 auf.On the spray disc 2, on its side directed into the interior of the shower head, a flat disc 13 is fastened, which is perpendicular to the axis of rotation of the screw 3. On the disc 13, a ring member 14 is rotatably supported, which can thus rotate around the screw 3. The ring element 14 has a toothing 15 on its inside.

Seitlich neben dar Schraube 3 ist an der Innenseite der Strahlscheibe 2 mit Hilfe einer in eine Buchse 16 eingreifenden Schraube 17 ein Zahnrad 18 drehbar gelagert. Das Zahnrad 18 kämmt einerseits mit der Verzahnung 15 des Ringelements 14 und andererseits mit einem weiteren Zahnrad 19. Das Zahnrad 19 wird von der Außenverzahnung einer Lagerbuchse 20 eines Turbinenrads 21 gebildet. Das Turbinenrad 20 ist mit seiner Lagerbuchse 20 an der Buchse 5 des Brausekopfs drehbar gelagert. Seine axiale Verschiebbarkeit ist durch entsprechende Schultern an der Buchse 5 bzw. an der Schraube 3 begrenzt. Das Turbinenrad 21 weist auf seiner der Strahlscheibe 2 abgewandten Seite einzelne schräg verlaufende Turbinenflügel 22 auf.To the side of the screw 3, a gear wheel 18 is rotatably mounted on the inside of the jet disc 2 with the aid of a screw 17 engaging in a bushing 16. The gear wheel 18 meshes on the one hand with the toothing 15 of the ring element 14 and on the other hand with another toothed wheel 19. The toothed wheel 19 is formed by the external toothing of a bearing bush 20 of a turbine wheel 21. The turbine wheel 20 is rotatably supported with its bearing bush 20 on the bush 5 of the shower head. Its axial displaceability is limited by corresponding shoulders on the socket 5 or on the screw 3. The turbine wheel 21 has on its side facing away from the jet disk 2 individual inclined turbine blades 22.

Aus dem hohlen Griff gelangt das Wasser durch eine Öffnung 23 in das Innere des Brausekopfs. Die Öffnung ist so angeordnet, daß das Wasser auf die Flügel 22 des Turbinenrads 21 trifft. Es strömt etwas schräg in den Brausekopf ein, so daß es die Flügel 22 beaufschlagt. Durch das einströmende Wasser wird das Turbinenrad 21 in Drehung versetzt. Das einstückig an dem Turbinenrad 21 angeformte Zahnrad 19 verdreht das an der Strahlscheibe 2 angeordnete Zahnrad 18, das seinerseits das Ringelement 14 verdreht.The water reaches the interior of the shower head through an opening 23 from the hollow handle. The opening is arranged so that the water hits the blades 22 of the turbine wheel 21. It flows somewhat obliquely into the shower head so that it acts on the wings 22. The turbine 21 is rotated by the inflowing water. The gear 19 integrally formed on the turbine wheel 21 rotates the gear 18 arranged on the jet disk 2, which in turn rotates the ring element 14.

In der Zylindermantel-Außenfläche 24 des Ringelements 14 ist eine über den gesamten Umfang verlaufende geschlossene Nut 25 eingeformt. Jedes Segment 10 weist an seiner Kreisbogen-Innenseite einen etwa mittig angeordneten Zapfen 26 auf, der in diese Nut 25 eingreift. Bei Verdrehung des Ringelements gegenüber den in Umfangsrichtung stehenbleibenden Segmenten 10 folgen die Zapfen 26 also der Form der Nut.In the outer cylinder surface 24 of the ring element 14 there is a closed groove 25 extending over the entire circumference molded. Each segment 10 has on its inside of a circular arc an approximately centrally arranged pin 26 which engages in this groove 25. When the ring element is rotated relative to the segments 10 which remain in the circumferential direction, the pins 26 thus follow the shape of the groove.

Fig. 4a zeigt eine mögliche Form der Nut 25 in der Zylindermantel-Außenfläche 24 eines Ringelements 14. Das Ringelement 14 ist in der gleichen Orientierung dargestellt wie in Fig. 1, so daß in Fig. 4a unten die Strahlscheibe zu denken ist. Die Nut 25 verläuft über den größten Teil des Umfangs parallel zu der ebenen Stirnfläche des Ringelements 14 und enthält nur einen Abschnitt, wo sich die Nut V-förmig oder auch U-förmig der unteren Stirnseite des Ringelements 14 nähert. In diesem Abschnitt 25a wird das jeweils zugeordnete Segment 10 in Richtung auf die Strahlscheibe 2 verschoben, so daß die Stifte 12 in die Strahlaustrittsöffnungen 7 eindringen. Dies ist links in Fig. 1 dargestellt. Während der übrigen Position des Ringelements sind die Segmente nach oben verschoben, so daß die Stifte 12 aus den Strahlaustrittsöffnungen 7 ausgerückt sind. Die Kurvenform der Nut 25 der Fig. 4a bedeutet also, daß immer nur ein einzelnes Segment 10 mit seinen Stiften so verschoben ist, daß diese in die Strahlaustrittsöffnungen 7 eingreifen.Fig. 4a shows a possible shape of the groove 25 in the outer cylinder surface 24 of a ring member 14. The ring member 14 is shown in the same orientation as in Fig. 1, so that in Fig. 4a below the jet disc is to be thought. The groove 25 extends over most of the circumference parallel to the flat end face of the ring element 14 and contains only a section where the groove approaches the lower end face of the ring element 14 in a V-shape or a U-shape. In this section 25a, the respectively assigned segment 10 is displaced in the direction of the jet disk 2, so that the pins 12 penetrate into the jet outlet openings 7. This is shown on the left in Fig. 1. During the remaining position of the ring element, the segments are shifted upward, so that the pins 12 are disengaged from the beam outlet openings 7. The curve shape of the groove 25 of FIG. 4a thus means that only a single segment 10 with its pins is displaced so that they engage in the beam outlet openings 7.

Bei der in Fig. 4b dargestellten Form der Nut 25 erfolgt ein ständiges Auf- und Abbewegen der Stifte 12 in die Strahlaustrittsöffnungen 7 hinein und aus ihnen heraus.In the shape of the groove 25 shown in FIG. 4b, the pins 12 are constantly moved up and down into the beam outlet openings 7 and out of them.

Bei der Ausführungsform der Fig. 1 sind die Stifte 12 zu Gruppen zusammengefaßt, wobei jede Gruppe von Stiften an einem Segment 10 ausgebildet ist. Diese Segmente 10 können durch die Kurvenführung einzeln bewegt werden. In der dargestellten Ausführungsform dient zur Bewegung aller Segmente eine einzige Nut 25. Es ist selbstverständlich auch möglich, an der Außenfläche 24 des Ringelements mehrere Nuten anzuordnen, und die Segmente mit ihren Zapfen 26 in unterschiedliche Nuten eingreifen zu lassen. Auf diese Weise kann ein größerer Freiheitsgrad an möglichen Bewegungen bewirkt werden.In the embodiment of FIG. 1, the pins 12 are combined into groups, each group of pins being formed on a segment 10. These segments 10 can be moved individually by the curve guidance. In the embodiment shown, all segments are moved a single groove 25. It is of course also possible to arrange a plurality of grooves on the outer surface 24 of the ring element and to allow the segments to engage with their grooves 26 in different grooves. In this way, a greater degree of freedom in possible movements can be achieved.

Es ist ebenfalls möglich, statt der Zusammenfassung von drei konzentrischen Bögen von Stiften 12, die Stifte jeweils eines Bogens oder auch eines geschlossenen Kreises als Gruppe zusammenzufassen, so daß dann die Stifte der drei verschiedenen konzentrischen Kreise unterschiedlich bewegt werden würden. Dies könnte beispielsweise dadurch geschehen, daß die Stifte des weiter außen liegenden Kreises von Strahlaustrittsöffnungen mit einem eigenen Ringelement in eine andere Nut in Fig. 1 oberhalb der Nut 25 eingreifen würden.It is also possible, instead of combining three concentric arcs of pins 12, to combine the pins of one arc or of a closed circle as a group, so that the pins of the three different concentric circles would then be moved differently. This could be done, for example, by the pins of the circle of beam outlet openings lying further outside engaging with a separate ring element in another groove in FIG. 1 above the groove 25.

Durch entsprechende Dimensionierung der Verzahnungen 15, 18 und 19 läßt sich dafür sorgen, daß mit dem üblichen Wasserdruck eine Reinigungswirkung erreicht werden kann.By appropriate dimensioning of the teeth 15, 18 and 19 can ensure that a cleaning effect can be achieved with the usual water pressure.

An der Außenseite des Ringelements 14 ist bei der Ausführungsform der Fig. 5 - 8 eine Sperrklinke 27 angeformt, die federnd ausgebildet ist und mit ihrem Ende an einem Teil 21 des Brausekopfs federnd anliegt. Dieses Teil 21 des Brausekopfs weist in Fig. 1 nicht zu sehende, quer zur Umfangsrichtung verlaufende Anlageflächen auf, an denen die Sperrklinke 27 anliegen kann.In the embodiment of FIGS. 5-8, a pawl 27 is formed on the outside of the ring element 14, which is designed to be resilient and rests with its end against a part 21 of the shower head. This part 21 of the shower head has, in FIG. 1, invisible contact surfaces running transversely to the circumferential direction, against which the pawl 27 can rest.

Die Sperrklinke 27 weist die Form einer federnden Zunge 28 auf und ist an zwei diametral versetzten Stellen des Ringelements 14 an dessen Oberseite angeformt. Die federnden Zungen 28 liegen radial etwas weiter außen als die Zylinderaußenfläche des Ringelements. Sie erstrecken sich unter einem Winkel von etwa 15° gegenüber der Ebene der Oberseite des Ringelements und sind relativ dünn und schmal ausgebildet. Sie enden in einer ebenen Stirnfläche 29, die senkrecht zu der Ebene der Oberseite des Ringelements 14 und senkrecht zu der durch den Pfeil 30 dargestellten Umfangsrichtung verlaufen. In Fig. 6 ist die Ansicht des Ringelements 14 von oben dargestellt, wobei die in Fig. 2 und Fig. 1 angedeutete Verzahnung 15 hier nur angedeutet ist. Die beiden Sperrklinken sind an den Enden von radialen Vorsprüngen 31 angeformt und verlaufen längs eines Kreisbogens.The pawl 27 has the shape of a resilient tongue 28 and is formed on two diametrically offset points of the ring element 14 on the upper side thereof. The resilient tongues 28 are located slightly further radially outward than the outer cylinder surface of the ring element. They extend under one Angles of about 15 ° to the plane of the top of the ring element and are relatively thin and narrow. They end in a flat end face 29 which is perpendicular to the plane of the top of the ring element 14 and perpendicular to the circumferential direction shown by the arrow 30. FIG. 6 shows the view of the ring element 14 from above, the toothing 15 indicated in FIGS. 2 and 1 being only indicated here. The two pawls are formed at the ends of radial projections 31 and run along an arc of a circle.

Das Gegenelement, mit dem die federnden Zungen 28 zur Bildung einer Sperre zusammenwirken, ist eine in Fig. 7 dargestellte Verteilerscheibe 32, die bei der Ausführungsform nach Fig. 1 nicht vorhanden ist. Bei der Ausführungsform nach Fig. 1 wäre eine entsprechende Ausbildung an dem Brauseteil 21 vorgesehen.The counter element with which the resilient tongues 28 cooperate to form a lock is a distributor disk 32 shown in FIG. 7, which is not present in the embodiment according to FIG. 1. In the embodiment according to FIG. 1, a corresponding design would be provided on the shower part 21.

Die Unterseite der Verteilerscheibe 32 enthält einen glatten breiten, kreiszylindrischen Ring 33, der einzelne taschenartige Vertiefungen 34 aufweist. Diese taschenartigen Vertiefungen sind an der radialen Stelle angeordnet, an der auch die federnden Zungen 28 angeordnet sind. Die in radialer Richtung gemessene Breite der taschenartigen Ausnehmungen 34 ist etwas größer als die entsprechende Breite der federnden Zungen 28, so daß diese, wenn sie in den Ausnehmungen 34 liegen, durch die Seitenwände geführt sind.The underside of the distributor disk 32 contains a smooth, wide, circular cylindrical ring 33 which has individual pocket-like depressions 34. These pocket-like depressions are arranged at the radial point at which the resilient tongues 28 are also arranged. The width of the pocket-like recesses 34, measured in the radial direction, is somewhat larger than the corresponding width of the resilient tongues 28, so that when they lie in the recesses 34, they are guided through the side walls.

Beim normalen Betätigen der Reinigungseinrichtung durch den Wasserdruck ist die Anordnung so getroffen, daß das Ringelement 14 entgegengesetzt zur Richtung des Pfeiles 30 in Fig. 6 rotiert. Die federnden Zungen bewegen sich also derart, daß ihre Stirnflächen 29 in Drehrichtung hinten angeordnet sind. Die Zungen 28 können also in Richtung des Pfeils 35 in Fig. 7 über den Ring 33 gleiten, wobei die Enden 29 dann in die Ausnehmung 34 fallen.During normal actuation of the cleaning device by the water pressure, the arrangement is such that the ring element 14 rotates in the opposite direction to the arrow 30 in FIG. 6. The resilient tongues thus move in such a way that their end faces 29 are arranged at the rear in the direction of rotation. The tongues 28 can thus in the direction of arrow 35 in FIG. 7 Slide over the ring 33, the ends 29 then falling into the recess 34.

Soll nun eine schwergängig oder unbeweglich gewordene Reinigungseinrichtung von Hand wieder gelöst werden, so wird an der Strahlscheibe 2 der Brause der Fig. 1 von Hand gedreht. Wenn die Stifte 12 in den Strahlaustrittslöchern 7 angeordnet und dort festgelegt sind, so führt diese Verdrehung dazu, daß das Ringelement 14 mitgedreht wird. Dies ist möglich, da das Turbinenrad 22 in keiner Weise an der Drehung gehindert wird, selbst dann nicht, wenn Wasserdruck auf ihm liegt.If a cleaning device that has become stiff or immobile is to be loosened again by hand, then the spray head of FIG. 1 is rotated by hand on the jet disc 2. If the pins 12 are arranged in the beam outlet holes 7 and fixed there, this rotation leads to the ring element 14 also being rotated. This is possible because the turbine wheel 22 is in no way prevented from rotating, even when water pressure is on it.

Der Brausekopf wird nun so bewegt, daß das Ringelement 14 in Richtung des Pfeiles 30 in Fig. 6 verdreht wird. Dadurch sind jetzt die Stirnflächen 29 der federnden Zunge 28 in Drehrichtung vorne, sie rutschen über den Ring 33 in die Vertiefungen 34, bis sie an deren Stirnflächen 36 anliegen. Dadurch ist eine Weiterdrehung des Ringelements 14 verhindert. Bei Weiterdrehung der Strahlscheibe werden die Zapfen 26 längs der Nut 25 verschoben, was zu einer Kraftkomponente in Längsrichtung der Zapfen 12 und damit zu ihrem Ausrücken aus den Strahlaustrittslöchern führt. Damit wird aber die Reinigungseinrichtung wieder gelöst, so daß sie von nun an wieder von dem strömenden Wasser betätigt werden kann.The shower head is now moved so that the ring element 14 is rotated in the direction of arrow 30 in FIG. 6. As a result, the end faces 29 of the resilient tongue 28 are now at the front in the direction of rotation, they slide over the ring 33 into the depressions 34 until they abut the end faces 36 thereof. This prevents further rotation of the ring element 14. As the jet disc rotates further, the pins 26 are displaced along the groove 25, which leads to a force component in the longitudinal direction of the pins 12 and thus to their disengagement from the jet exit holes. So that the cleaning device is released again, so that it can be operated from now on by the flowing water.
