Description

Die Erfindung betrifft einen Brausekopf mit einer Reinigungseinrichtung, die zum Reinigen der Strahlaustrittsöffnungen von Ablagerungen dient, wie sie sich durch Verunreinigungen des Leitungswassers oder durch Kalkablagerungen ergeben können.The invention relates to a shower head with a cleaning device, for cleaning the jet outlet openings of deposits as it is caused by contaminants tap water or limescale deposits can.

Es ist bereits ein Brausekopf dieser Art bekannt (EP-A-28 48 01), der zwei umschaltbare Brauseeinrichtungen aufweist. Beim Umschalten zwischen den beiden Brauseeinrichtungen wird die Reinigungseinrichtung für die Brauselöcher der einen Brauseeinrichtung automatisch betätigt.A shower head of this type is already known (EP-A-28 48 01), which has two switchable shower devices. At the Switching between the two shower devices is the Cleaning device for the shower holes of the one shower device automatically operated.

Weiterhin bekannt ist ein Brausekopf (US-A-1982538), bei dem eine Reinigungseinrichtung zur gleichzeitigen Reinigung aller Strahlaustrittsöffnungen der Strahlscheiben vorgesehen ist.Also known is a shower head (US-A-1982538) in which a cleaning device for the simultaneous cleaning of all Jet outlet openings of the jet disks is provided.

Weiterhin bekannt ist ein Brausekopf (EP-A-489398), bei dem eine Reinigungseinrichtung zur gleichzeitigen Reinigung aller Strahlaustrittsöffnungen der Strahlscheibe durch eine Schwenkbewegung vorgesehen ist. Also known is a shower head (EP-A-489398) in which a cleaning device for the simultaneous cleaning of all Beam outlet openings of the spray disc through a Swiveling movement is provided.

Bei diesen letztgenannten Reinigungseinrichtungen ist während des Reinigens ein Betrieb der Brause nicht möglich.In these latter cleaning facilities is during cleaning the shower is not possible.

Mit der Erfindung ist es möglich, ohne Abstellen des Wassers eine Reinigung einer Gruppe von Strahlaustrittsöffnungen durchzuführen. Die Zusammenfassung von Strahlöffnungen zu Gruppen braucht nur gedanklich zu sein. Beispielsweise können alle Strahlöffnungen längs eines Kreises angeordnet sein und die Reinigungseinrichtung derart ausgebildet sein, daß sie ebenfalls längs eines Kreises angeordnete Reinigungselemente aufweist, deren Abstand dem doppelten Lochabstand entspricht. Es läßt sich also jedes zweite Loch der Strahlscheibe mit einer Betätigung reinigen. Durch Verdrehen der Strahlscheibe oder des Rings von Reinigungselementen läßt sich dann bei der nächsten Betätigung jeweils die andere Gruppe von Strahlöffnungen reinigen. Der Abstand der Reinigungselemente könnte auch einem dreifachen Lochabstand entsprechen, so daß dann jedes dritte Loch gleichzeitig gereinigt werden könnte und somit drei Gruppen von Strahlöffnungen vorhanden wären.With the invention it is possible without turning off the water cleaning a group of jet outlets perform. The summary of jet openings too Groups only need to be mental. For example all jet openings must be arranged along a circle and the cleaning device be designed such that it cleaning elements also arranged along a circle has a distance equal to twice the hole spacing. So every second hole in the spray disc can be used one operation. By turning the spray disc or the ring of cleaning elements can then at next actuation the other group of jet openings clean. The distance between the cleaning elements could also correspond to a triple hole spacing, so that then every third hole could be cleaned at the same time and thus there would be three groups of jet openings.

Bei nur einer Gruppe von Reinigungselementen gibt es eine Stellung, in der alle Strahlaustrittsöffnungen frei von den Reinigungselementen sind, so daß das Wasser aus allen Austrittsöffnungen austritt.If there is only one group of cleaning elements, there is one Position in which all jet outlets are free of Cleaning elements are so that the water from all outlet openings exit.

Bei mehreren Gruppen von Reinigungselementen kann in Weiterbildung der Erfindung vorgesehen sein, daß die Betätigungseinrichtung mindestens eine Stellung aufweist, in der alle Gruppen von Reinigungselementen außer Eingriff mit den Strahlöffnungen sind.In the case of several groups of cleaning elements, further training can be carried out the invention provide that the actuator has at least one position in which all Groups of cleaning elements out of engagement with the Are jet openings.

Drosseleinrichtung aufweisen, die die Wasserzufuhr zu der Gruppe von Strahlaustrittsöffnungen drosselt, mit denen die Reinigungselemente in Eingriff stehen oder gerade in Eingriff gebracht werden. Dies kann dazu dienen, die Betätigungseinrichtung für die Reinigungseinrichtung leichtgängiger zu machen, da dann die Querschnitte der Reinigungselemente nicht als hydraulisch beaufschlagte Kolbenflächen auftreten. Zusätzlich hat dieses Merkmal den Vorteil, daß aus dem zu reinigenden Strahlring kein undefiniertes Rinnsal ausfließt.According to the invention, the shower head can be a further development Have switching or throttle device that the water supply throttles to the group of jet outlets, with which the cleaning elements are engaged or being engaged. This can serve the actuating device for the cleaning device to make it easier to move because then the cross sections of the Cleaning elements not as hydraulically loaded Piston surfaces occur. This feature also has the Advantage that no undefined from the jet ring to be cleaned Trickle flows out.

Erfindungsgemäß kann vorgesehen sein, daß die Zahl der Gruppen von Reinigungselementen der Zahl von Gruppen von Strahlaustrittsöffnungen gleich ist. In diesem Fall kann der Brausekopf bzw. die Reinigungseinrichtung einfach aufgebaut sein, da keine komplizierteren Bewegungen zur Ausrichtung der Reinigungselemente mit unterschiedlichen Gruppen von Strahlaustrittsöffnungen mehr erforderlich sind.According to the invention it can be provided that the number of Groups of cleaning elements of the number of groups of Beam outlet openings is the same. In this case, the Shower head or the cleaning device simply constructed as there are no more complicated movements to align the Cleaning elements with different groups of jet outlet openings are more needed.

Erfindungsgemäß kann in Weiterbildung ebenfalls vorgesehen sein, daß jede Gruppe von Reinigungselementen je einer Gruppe von Strahlöffnungen zugeordnet ist.According to the invention, further training can also be provided be that each group of cleaning elements one group at a time of jet openings is assigned.

Die Erfindung schlägt vor, daß die Betätigungseinrichtung für die Reinigungseinrichtung eine die Bewegung der Reinigungselemente steuernde Nut aufweisen kann. Diese Nut läßt sich bei der Herstellung des Brausekopf sehr einfach mit herstellen. Die Nut kann insbesondere sich über einen Umfang eines Teils des Brausekopfes erstrecken, so daß eine kontinuierliche Betätigung möglich wird. The invention proposes that the actuator for the cleaning device the movement of the cleaning elements can have controlling groove. This groove can be very easy to manufacture when manufacturing the shower head. The groove can in particular extend over a circumference extend part of the shower head so that a continuous Actuation becomes possible.

Erfindungsgemäß kann vorgesehen sein, daß für jede Gruppe von Reinigungselementen eine eigene Nut vorgesehen ist. Die Koordinierung der Bewegung jeder Gruppe von Reinigungselementen erfolgt dann dadurch, daß die Nuten entweder am gleichen Teil oder an miteinander starr verbundenen Teile angeordnet sind.According to the invention it can be provided that for each group of Cleaning elements a separate groove is provided. The Coordinate the movement of each group of cleaning elements then takes place in that the grooves either on same part or on parts rigidly connected to each other are arranged.

Besonders einfach gestaltet sich der Brausekopf dann, wenn die Reinigungselemente durch Verdrehen der Strahlscheibe betätigt werden können.The shower head is particularly simple when the cleaning elements by turning the spray disc can be operated.

Die Erfindung schlägt vor, daß die Strahlöffnungen ringförmig angeordnet sein können. Insbesondere kann jede Gruppe von Strahlöffnungen einen Kreisring unterschiedlichen Durchmessers bilden. Die Strahlscheibe weist dann beispielsweise zwei konzentrische kreisförmige Ringe von Strahlöffnungen auf, von denen jeder Ring eine Gruppe bildet.The invention proposes that the jet openings are annular can be arranged. In particular, each group of Beam openings form a circular ring of different diameters form. The spray disc then points, for example two concentric circular rings of jet openings of which each ring forms a group.

Erfindungsgemäß kann vorgesehen sein, daß die Reinigungselemente Stifte sind, deren Durchmesser dem Durchmesser der Strahlaustrittsöffnungen annähernd gleich ist. Beim Einschieben der Stifte werden Ablagerungen in den Öffnungen durch diese nach außen gestoßen.According to the invention it can be provided that the cleaning elements Pins are whose diameter is the diameter of the Beam outlet openings is approximately the same. When inserting of the pens will become deposits in the openings pushed this outward.

Erfindungsgemäß kann vorgesehen sein, daß die Stifte an einem Ringelement angeformt sind, das sich in Längsrichtung der Stifte verschieben läßt. Auf diese Weise ist eine einfache Bewegungsmöglichkeit vorgesehen.According to the invention it can be provided that the pins on one Ring element are formed, which is in the longitudinal direction of the Can move pins. This way is an easy one Possibility of movement provided.

In nochmaliger Weiterbildung der Erfindung kann vorgesehen sein, daß bei einer vollständigen Umdrehung der Strahlscheibe sich die möglichen Stellungen der Betätigungseinrichtung mehr als einmal wiederholen, insbesondere zweimal oder dreimal.In a further development of the invention can be provided be that with a complete revolution of the jet disc the possible positions of the actuating device more Repeat as once, especially twice or three times.

Figur 1 zeigt eine Stellung, in der die Reinigungselemente 30 in die Strahlaustrittsöffnungen 12 der äußeren Strahlscheibe 10 eingefahren sind.An annular space is located outside the web 25 of the ring element 24 27 formed, the outward of an apron 28 of the outer jet 10 is limited. In this annulus a ring element 29 is mounted, on the underside of which cleaning elements 30 are formed for the outer beam ring. The ring element 29 engages with molded on its inside radial projections 31 into the groove 26. Figure 1 shows a position in which the cleaning elements 30 in the Jet exit openings 12 of the outer jet disk 10 are retracted.

An der äußeren Strahlscheibe 10 ist im Bereich der Außenseite ein Betätigungsring 32 befestigt, an dem ein Benutzer angreifen kann und mit dessen Hilfe er die beiden Strahlscheiben um die aus dem Verteilerelement 5 und die Kernhülse 8 gebildete Einheit verdrehen kann. Bei dieser Verdrehung werden auch die beiden Ringelemente 18 und 29 mit verdreht, wobei ihre axiale Stellung durch die Form der Nuten 21 und 26 bestimmt ist.On the outer jet disc 10 is in the area of the outside an actuating ring 32 is attached to which a user can attack can and with the help of which he the two jet disks around the from the distributor element 5 and the core sleeve 8 formed unit can twist. With this twist the two ring elements 18 and 29 are also rotated, their axial position being determined by the shape of the grooves 21 and 26 is determined.

In Figur 1 sind die Reinigungselemente 30 für die Strahlaustrittsöffnungen 12 der äußeren Strahlscheibe 10 in diese eingefahren und die Reinigungselemente 19 für die Strahlaustrittsöffnungen 11 der inneren Strahlscheibe 9 aus diesen herausgefahren. Werden nun die beiden Strahlscheiben um eine Winkel von 60° verdreht, so werden die Reinigungselemente 30 aus den Strahlaustrittsöffnungen herausgefahren und die Reinigungselemente 19 in die Strahlaustrittsöffnungen 11 hineingeschoben. Diese Situation ist in Figur 2 dargestellt. Diese zeigt einen Schnitt durch den Brausekopf in einer um 60° verdrehten Stellung der Strahlscheiben. Es ist zu sehen, daß der Schnitt durch den Radialabschnitt 13 der äußeren Strahlscheibe 10 jetzt nur die radialen Kanäle 15 zeigt, während die Hohlräume 14 nach unten hin abgeschlossen sind. Das Wasser strömt also nur zu dem äußeren Strahlkranz der äußeren Strahlscheibe 10.In Figure 1, the cleaning elements 30 for the jet outlet openings 12 of the outer jet disc 10 in this retracted and the cleaning elements 19 for the jet outlet openings 11 of the inner jet disc 9 from these pulled out. Now the two jet disks by one Twisted angle of 60 °, the cleaning elements 30 moved out of the beam outlet openings and the Cleaning elements 19 into the jet outlet openings 11 pushed in. This situation is shown in Figure 2. This shows a section through the shower head in one order 60 ° rotated position of the spray discs. It can be seen, that the section through the radial section 13 of the outer Spray disc 10 now only shows the radial channels 15, while the cavities 14 are closed at the bottom. So the water only flows to the outer rim of the outer spray disc 10.

Figur 3 zeigt in einem gestrichelten Verlauf eine Abwicklung der Nuten 26 und 21 und die zugehörige Stellung der Reinigungselementen 30 bzw. 19. Die Abwicklung der Figur 3 soll eine vollständige Umdrehung der Strahlscheiben darstellen. In der links in Figur 3 dargestellten Stellung, die dem Schnitt der Figur 1 entspricht, sind die Reinigungselemente 30 in die Öffnungen der Strahlscheibe eingefahren, während die Reinigungselemente 19 für die innere Strahlscheibe aus den Öffnungen herausgefahren sind, was durch die dargestellte Wasserstrahlen angedeutet ist. Wird nun die Strahlscheibe um 60° verdreht, so werden die Reinigungselemente 30 aus den Löchern herausgefahren und die Reinigungselemente 19 in die Löcher eingefahren. Bei einer nochmals weiteren Drehung um 60° sind nun beide Gruppen von Reinigungselementen aus den Löchern herausgefahren, so daß das Wasser aus allen Austrittsöffnungen austritt. Bei einer nochmals weiteren Verdrehung um 60° ist die ganz links dargestellte Ausgangsstellung wieder erreicht. Bei einer Umdrehung um 180° sind also alle möglichen Stellungen durchlaufen. Die Strahlscheiben lassen sich aber beliebig weit verdrehen, so daß während der vollständigen Umdrehung alle Stellungen der Betätigungseinrichtung und damit der Reinigungseinrichtung zweimal eingenommen werden.Figure 3 shows a development in a dashed line the grooves 26 and 21 and the associated position of the cleaning elements 30 and 19. The processing of Figure 3 should represent a complete revolution of the jet disks. In the position shown on the left in Figure 3, the section 1 corresponds to the cleaning elements 30 in the Openings of the spray disc retracted while the cleaning elements 19 for the inner spray disc from the openings are brought out what is shown by the Water jets is indicated. Now the spray disc is around Twisted 60 °, the cleaning elements 30 from the Drilled holes and the cleaning elements 19 in the Holes retracted. With another rotation 60 ° are now two groups of cleaning elements from the Drilled out holes so that the water from all outlet openings exit. With another twist the starting position shown on the far left is 60 ° reached again. With a rotation of 180 °, all are possible positions. Leave the spray disks but twist as much so that during the complete Revolution all positions of the actuating device and thus taken twice by the cleaning device will.

Bei der dargestellten Ausführungsform sind zwei konzentrische Reihen von Austrittsöffnungen vorhanden, die jeweils eine Gruppe von Austrittsöffnungen bilden. Für jede Gruppe von Austrittsöffnungen ist eine Gruppe von Reinigungselementen vorhanden. Es ist selbstverständlich auch möglich, drei konzentrische Reihen von Strahlaustrittsöffnungen vorzusehen. Um den mechanischen Aufwand dann klein zu halten, können beispielsweise zwei benachbarte Reihen von Strahlaustrittsöffnungen mit einer gemeinsamen Gruppe von Reinigungselementen gereinigt werden. Das gleiche würde auch für vier Reihen gelten.In the illustrated embodiment, two are concentric Rows of outlet openings, each one Form a group of outlet openings. For each group of Outlet openings is a group of cleaning elements available. It is of course also possible to have three provide concentric rows of jet outlets. To keep the mechanical effort small, you can for example two adjacent rows of jet outlets with a common group of cleaning elements getting cleaned. The same would happen for four Rows apply.

Wichtig ist jedoch, daß es eine Stellung der Reinigungseinrichtung gibt, in der alle Strahlaustrittsöffnungen durchströmt werden, so daß die Reinigungseinrichtung nicht in Funktion ist. Andererseits gibt es aber auch keine Stellung, in der alle Strahlaustrittsöffnungen durch Reinigungselemente verschlossen sind.However, it is important that there is a position of the cleaning device there, in which flows through all jet outlet openings be so that the cleaning device is not in Function is. On the other hand, there is no position in which all jet outlet openings through cleaning elements are closed.

Die Erfindung ist natürlich auch anwendbar, wenn es nur eine Reihe von Austrittsöffnungen gibt, da dann einfach die Reinigungselemente einen Abstand aufweisen würden, der dem doppelten Abstand von Strahlaustrittsöffnungen entspricht. In diesem Fall müßte die Nut für die Reinigungseinrichtung so ausgebildet sein, daß bei Verdrehung die Reinigungselemente aus den Strahlaustrittsöffnungen herausgezogen und nach einer weiteren Verdrehung in die jeweils dazwischen liegenden Strahlaustrittsöffnungen eingefahren werden. Auch in diesem Fall gibt es eine Stellung, in der alle Austrittsöffnungen frei sind, und keine Stellung, in der alle Strahlaustrittsöffnungen durch Reinigungselemente verschlossen sind.The invention is of course also applicable if there is only one Row of outlet openings there, because then simply the Cleaning elements would have a distance that the corresponds to twice the distance from the beam outlet openings. In this case, the groove for the cleaning device should be like this be formed that the cleaning elements when twisted pulled out of the jet outlet openings and after one further twisting into the one in between Beam outlet openings are retracted. Also in this Case there is a position in which all outlet openings are free, and no position in which all jet outlet openings are closed by cleaning elements.
