Abstract

The shower head has inside it a device by which the amount of water going out through a jet outlet aperture can be altered relatively slowly. This device may be driven by a turbine wheel (6) inside the head. When there are two jet outlet apertures to create two different forms of jet, the device can be used to switch automatically between them. The casing (1) has a cylindrical jacket (3) with a free endface (4) forming an aperture in which a jet washer with a number of jet outlet apertures is fitted.

Description

Die Erfindung geht aus von einem Brausekopf mit einem Brausekopfgehäuse, aus dem ein Wasserstrahl durch mindestens eine Strahlaustrittsöffnung einer Strahlscheibe austritt. Brauseköpfe dieser Art sind als Kopfbrausen, Handbrausen und auch als Seitenbrausen bekannt.The invention is based on a shower head with a shower head housing, from which a jet of water passes through at least one Beam outlet opening of a spray disc emerges. Shower heads of this type are available as overhead showers, hand showers and also known as body showers.

Bei Brausen sind Einrichtungen bekannt, um manuell zwischen mehreren Strahlarten umzuschalten, beispielsweise einem harten Strahl und einem belüfteten und eher weichen Wasserstrahl. Hierzu sind an den Brauseköpfen Umschaltgriffe vorgesehen, beispielsweise ein Knebelgriff.With showers, facilities are known to manually switch between switch several jet types, for example a hard one Jet and a ventilated and rather soft water jet. For this purpose, switch handles are provided on the shower heads, for example a toggle handle.

Weiterhin bekannt sind Massagebrausen, bei denen ein Wasserstrahl von einem in dem Brausekopf angeordneten Element mit hoher Frequenz unterbrochen wird. Der sich daraus ergebende Strahl besteht also aus einer Folge kurzer Strahlen, wobei die Unterbrechungen jedoch so kurz sind, daß der Benutzer die Schaltvorgänge nicht erkennen kann. Bei einer solchen bekannten Massagebrause (US-A-4 101 075) ist ein Rotor vorhanden, der von dem Brausewasser rotierend angetrieben wird und die Strahlöffnungen bei jeder Umdrehung abwechselnd öffnet oder schließt. Massage showers in which a water jet is also known of an element arranged in the shower head high frequency is interrupted. The resulting one Ray consists of a sequence of short rays, whereby however, the interruptions are so short that the user can Switch operations can not recognize. In such a known Massage shower (US-A-4 101 075) there is a rotor, which is driven in rotation by the shower water and opens the jet openings alternately with each revolution or closes.

Bei einer weiteren bekannten Massagebrause (US-A-5 397 064) kann die Durchflußgeschwindigkeit eines an sich schon pulsierenden Wasserstrahls zyklisch zwischen zwei verschiedenen Werten verändert werden. Dies führt allerdings dazu, daß die Veränderung der Menge des austretenden Wassers auch zu einem Einfluß auf die Massageeinrichtung führt, so daß möglicherweise ungewünschte Wechselwirkungseffekte auftreten.In another known massage shower (US-A-5 397 064) can the flow rate of an already pulsating Water jet cyclically between two different Values are changed. However, this leads to the fact that Change in the amount of water exiting also to one Influence on the massage device leads, so that possibly undesired interaction effects occur.

Weiterhin bekannt ist ein Brausekopf mit einer automatisch betätigten Reinigungseinrichtung, bei dem von einer Turbine Reinigungszapfen in Strahlaustrittsöffnungen eingeschoben werden.A shower head with an automatic is also known actuated cleaning device in the case of a turbine The cleaning pin is inserted into the jet outlet openings will.

Der Erfindung liegt die Aufgabe zugrunde, eine in ihrem Gebrauchsverhalten verbesserte Brause zu schaffen.The invention is based, one in their use behavior the task to create improved showerhead.

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. Training the invention are the subject of dependent claims.

Im Gegensatz zu den bekannten Massagestrahlen wird also bei dem Brausekopf nach der Erfindung eine kontinuierliche Verringerung und anschließend wieder Vergrößerung der Menge des austretenden Wassers bewirkt, wobei die Verringerung und/oder Vergrößerung so langsam ist, daß der Benutzer diese Wirkung sowohl sehen als auch fühlen kann. Beispielsweise erfolgt eine Verringerung des Querschnitts von einer maximalen Öffnungstellung bis zu einer Stellung minimaler Öffnung und wieder zurück, wobei die Dauer für einen solchen Vorgang im Sekundenbereich liegt.In contrast to the known massage jets, the shower head according to the invention a continuous reduction and then again increasing the amount of escaping water causes the reduction and / or Magnification is so slow that the user has this effect can both see and feel. For example a reduction in the cross-section from a maximum opening position to a position of minimal opening and back again, the duration for such a process in Seconds range.

In Weiterbildung der Erfindung kann vorgesehen sein, daß der Brausekopf zwei Gruppen mit je mindestens einer Strahlaustrittsöffnung aufweist, wobei für beide Gruppen von Strahlaustrittsöffnungen eine eigene Wasserführung vorhanden ist. Hier kann, wie von der Erfindung vorgeschlagen wird, die Mengenänderungseinrichtung derart ausgebildet sein, daß sie zwischen den beiden Gruppen von Strahlaustrittsöffnungen hin- und herschaltet. In dem oben erwähnten Beispiel einer Brause mit einem harten und einem belüfteten weichen Strahl kann die Mengenänderungseinrichtung also beispielsweise in dem Sekundenbereich zwischen den beiden Strahlarten umschalten.In a further development of the invention it can be provided that the Shower head two groups, each with at least one jet outlet has, wherein for both groups of beam outlet openings its own water supply is available. Here, as proposed by the invention, the quantity change device be designed so that they between the two groups of beam outlets back and forth switched. In the example above a shower with a hard and a ventilated soft jet, the Quantity change device, for example, in the seconds range switch between the two jet types.

Eine Möglichkeit, wie die Menge des austretenden Wassers verändert werden kann, besteht darin, in der Wasserführung zu der Strahlaustrittsöffnung und/oder zu der Gruppe von Wasseraustrittsöffnungen ein Drosselelement anzuordnen, das insbesondere den wirksamen Querschnitt der zugeordneten Wasserführung verändert.One way how the amount of water leaking changes can be, is in the water supply too the jet outlet opening and / or to the group of water outlet openings to arrange a throttle element, in particular the effective cross section of the assigned water supply changed.

Der Antrieb für die Mengenänderungseinrichtung kann insbesondere von dem fließenden Wasser abgeleitet werden, beispielsweise indem man die Temperatur des Brausewassers, die in der Regel höher als die Umgebungstemperatur ist, über ein Peltierelement zur Gewinnung von elektrischer Spannung ausnutzt. Damit läßt sich dann ein Elektromotor antreiben, der die Veränderung des Querschnitts bewirkt.The drive for the quantity change device can in particular derived from the flowing water, for example by checking the temperature of the shower water in the Usually higher than the ambient temperature, via a Peltier element exploits to generate electrical voltage. This can then be used to drive an electric motor to make the change of the cross section.

Besonders günstig ist es jedoch, wenn, wie von der Erfindung ebenfalls vorgesehen wird, die Mengenänderungseinrichtung ein Turbinenrad aufweist, das über ein mechanisches Getriebe mit dem Drosselelement verbunden ist. Auf diese Weise kann bei einfachem Aufbau auch schon bei kaltem Wasser eine Änderung des Querschnitts erfolgen.However, it is particularly favorable if, as of the invention is also provided, the quantity change device Turbine wheel that has a mechanical transmission with the throttle element is connected. That way, at simple assembly even in cold water a change of the cross section.

Insbesondere kann vorgesehen sein, daß das Drosselelement zwei relativ zueinander bewegbare, mit je mindestens einer Öffnung versehene Teile aufweist, die mindestens im Bereich der Öffnungen aneinander anliegen. Dabei wird dann der wirksame Querschnitt der Wasserführung durch die gemeinsame Projektion der beiden Öffnungen in die Berührungsebene bestimmt. Wenn die Teile so verschoben werden, daß sich die Öffnungen nicht mehr decken, ist der wirksame Querschnitt der Wasserführung dann auf Null verändert.In particular, it can be provided that the throttle element two movable relative to each other, each with at least one Has opening provided parts, at least in the area of the openings lie against each other. The effective one Cross-section of the water flow through the common projection of the two openings in the plane of contact. If the parts are moved so that the openings no longer cover is the effective cross section of the water supply then changed to zero.

Insbesondere kann vorgesehen sein, daß beide relativ zueinander bewegbaren Teile als Scheiben ausgebildet sind, insbesondere als ebene Scheiben, von denen mindestens eine verdrehbar ausgebildet ist.In particular, it can be provided that both are relative to one another movable parts are designed as disks, in particular as flat disks, at least one of which can be rotated is trained.

Die Verdrehung ist eine bei einem üblicherweise im Querschnitt kreisrunden Brausekopf geeignete Form, bei der sowohl eine einfache Verstellung gegeben ist als auch eine große Fläche zur Verfügung steht.The twist is usually one in cross section circular shower head suitable shape, where both a simple adjustment is given as well as a large one Space is available.

Insbesondere kann die Mengenänderungseinrichtung derart ausgebildet sein, daß sie bei Verkleinerung des wirksamen Querschnitts der einen Wasserführung den wirksamen Querschnitt der anderen Wasserführung vergrößert. Es erfolgt auf diese Weise also ein allmähliches Umschalten zwischen den beiden Wasserführungen und damit auch den beiden Gruppen von Strahlaustrittsöffnungen. Hierdurch kann ein besonders angenehmer Effekt erreicht werden, insbesondere dann, wenn das Umschalten zwischen einem harten Strahl und dem weichen belüfteten Strahl erfolgt. Es kann insbesondere auch vorgesehen werden, daß das Umschalten in der einen Richtung schneller erfolgt als das Umschalten in der anderen Richtung.In particular, the quantity change device can be designed in this way be that when reducing the effective cross section one channel of water the effective cross section the other water channel enlarged. It is done on this So do a gradual switch between the two Water channels and thus also the two groups of jet outlet openings. This can be a particularly pleasant Effect can be achieved, especially when switching between a hard jet and the soft ventilated Beam occurs. In particular, it can also be provided that that switching in one direction is faster than switching in the other direction.

In nochmaliger Weiterbildung kann vorgesehen werden, daß die beiden Gruppen von Strahlaustrittsöffnungen konzentrisch angeordnet sind und eine der beiden Scheiben je eine in Umfangsrichtung verlaufende Öffnung für jede der beiden Wasserführungen aufweist.In a further training it can be provided that the two groups of jet outlet openings arranged concentrically are and one of the two discs each in the circumferential direction running opening for each of the two water channels having.

Der Schnitt der Fig. 1 zeigt aus Gründen der Vereinfachung nur einige Teile eines Brausekopfes, im dargestellten Beispiel einer Handbrause. Die Handbrause enthält ein Gehäuse, von dem nur ein Gehäuseteil 1 dargestellt ist. In das Gehäuse führt von rechts in Fig. 1 her ein Wassereinlaß, der beispielsweise von dem Inneren eines hohlen Handgriffs gebildet sein kann.The section of FIG. 1 shows for the sake of simplification only a few parts of a shower head, in the example shown a hand shower. The hand shower contains a housing of which only one housing part 1 is shown. In the case leads from the right in Fig. 1 ago a water inlet, for example formed by the inside of a hollow handle can be.

Das dargestellte Gehäuseteil 1 weist einen kreiszylindrischen Mantel 3 mit einer freien Stirnkante 4 auf, die eine Öffnung bildet. In die Öffnung wird zum Zusammenbau der Handbrause beispielsweise eine Strahlscheibe eingesetzt, die eine Vielzahl von Strahlaustrittsöffnungen aufweist. The housing part 1 shown has a circular cylindrical Sheath 3 with a free end edge 4, which has an opening forms. The hand shower is assembled in the opening For example, a spray disc is used, which is a variety of jet exit openings.

In der Achse des zylindrischen Mantels 3 ist an der Innenseite des dargestellten Gehäuseteils 1 eine Welle 5 angeformt, auf der ein Turbinenrad 6 drehbar gelagert ist. Das Turbinenrad 6 weist einzelne Schaufeln 7 auf, die von dem durch den Wassereinlaß 2 eintretenden Wasser in Drehbewegung versetzt werden. Das Wasser strömt dann an dem Turbinenrad 6 vorbei und von dort durch die Strahlaustrittsöffnungen der Strahlscheibe nach außen.In the axis of the cylindrical shell 3 is on the inside of the housing part 1 shown, a shaft 5 is formed, on which a turbine wheel 6 is rotatably mounted. The Turbine wheel 6 has individual blades 7, which of the rotating water entering through the water inlet 2 be transferred. The water then flows on the turbine wheel 6 over and from there through the beam outlet openings of the Spray disc to the outside.

Das Turbinenrad 6 weist an der Außenseite seiner Habe 8 eine Verzahnung 9 auf, die in axialer Richtung unterhalb des Turbinenrades 6 liegt. Mit der Verzahnung 9 der Habe 8 steht ein Zahnrad 10 in Eingriff. Dieses Zahnrad 10 weist zwei Zahnkränze auf, von denen der Zahnkranz mit dem kleineren Durchmesser mit der Verzahnung 9 der Nabe 8 des Turbinenrades 6 in Eingriff steht.The turbine wheel 6 has one on the outside of its property 8 Toothing 9 on the axial direction below the turbine wheel 6 lies. With the teeth 9 of the property 8 is a gear 10 is engaged. This gear 10 has two Sprockets on, of which the sprocket with the smaller one Diameter with the toothing 9 of the hub 8 of the turbine wheel 6 is engaged.

Koaxial zu der Welle 5 ist in dem Gehäuse des Brausekopfes ein erstes Scheibenelement 12 angeordnet und drehbar gelagert. Das Scheibenelement ist drehbar um die gleiche Achse wie das Turbinenrad 6 gelagert. Das Scheibenelement 12 weist auf seiner dem Turbinenrad 6 zugewandten Flachseite eine längs seines Umfangs angeordnete Schürze 13 auf. Die Schürze 13 ist auf ihrer radialen Innenseite mit einer Verzahnung 14 versehen. Mit dieser Verzahnung 14 steht die Außenverzahnung des größeren Zahnkranzes 11 des Zahnrades 10 in Eingriff. Eine Drehung des Turbinenrades führt daher zu einer Verdrehung des Scheibenelementes 12.Coaxial to the shaft 5 is in the housing of the shower head a first disc element 12 arranged and rotatably mounted. The disc element is rotatable about the same axis like the turbine wheel 6 mounted. The disc element 12 has on its flat side facing the turbine wheel 6 apron 13 arranged along its circumference. The skirt 13 has a toothing 14 on its radial inside Mistake. The external toothing is provided with this toothing 14 of the larger ring gear 11 of the gear 10 in engagement. A rotation of the turbine wheel therefore leads to a rotation the disk element 12.

Unmittelbar unterhalb des verdrehbaren Scheibenelementes 12 ist in dem Gehäuse der Handbrause ortsfest ein zweites Scheibenelement 15 angeordnet, das längs seines Umfangs gegenüber dem Gehäuse abgedichtet ist. Immediately below the rotatable disc element 12 is a second disc element fixed in the housing of the hand shower 15 arranged across its circumference the housing is sealed.

In Fig. 1 unterhalb des zweiten Scheibenelementes, d.h. in Strömungsrichtung stromab des Scheibenelementes 15, sind durch schematisch angedeutete koaxiale Zylinder 16, 17 zwei getrennte, durch die Pfeile 18 angedeutete Wasserführungen gebildet, die zu zugeordneten Gruppen von Strahlaustrittsöffnungen der Strahlscheiben führen. Beispielsweise führt die Wasserführung im Raum zwischen den beiden Zylindern 16, 17 zu einem äußeren Kranz von Strahlaustrittsöffnungen, die einen relativ harten Wasserstrahl erzeugen. Die Wasserführung innerhalb des inneren Zylinders 17 kann dann zu einem belüfteten Strahl führen.In Fig. 1 below the second disc element, i.e. in Flow direction downstream of the disc element 15, are by means of schematically indicated coaxial cylinders 16, 17 two separate water channels indicated by the arrows 18 formed to assigned groups of beam exit openings of the spray disks. For example, the Water flow in the space between the two cylinders 16, 17 too an outer ring of jet outlets that one generate a relatively hard water jet. The water flow inside of the inner cylinder 17 can then be ventilated Beam.

In Fig. 1 ist der Abstand zwischen den beiden Scheibenelementen 12, 15 vergrößert dargestellt.In Fig. 1 is the distance between the two disc elements 12, 15 shown enlarged.

Fig. 2 zeigt nun eine Aufsicht auf das Scheibenelement 12 der Brause nach Fig. 1, d.h. das in Strömungsrichtung zuerst angetroffene Scheibenelement 12. In seinem Mittelpunkt ist eine Öffnung 19 vorhanden, die zur Lagerung des Scheibenelementes 12 dient. Die Verzahnung 14 an der Innenseite der Schürze 13 ist nur im oberen Bereich zeichnerisch dargestellt. Sie erstreckt sich über den gesamten Innenumfang der Schürze 13.Fig. 2 now shows a plan view of the disc element 12 of the Shower according to Fig. 1, i.e. the one first encountered in the direction of flow Disc element 12. At its center is a Opening 19 available for the storage of the disc element 12 serves. The teeth 14 on the inside of the apron 13 is only shown graphically in the upper area. It stretches over the entire inner circumference of the apron 13.

An einer Stelle längs eines Radius' weist das Scheibenelement 12 in seinem Scheibenbereich eine Öffnung 20 auf, die überall etwa die gleiche Breite aufweist. Das an dem Turbinenrad 6 vorbeiströmende Wasser kann nur durch die Öffnung 20 des Scheibenelementes 12 weitergelangen.The disc element points at a point along a radius 12 in its pane area an opening 20 that everywhere has approximately the same width. That on the turbine wheel 6 flowing water can only through the opening 20 of the Disc element 12 reached further.

Fig. 3 zeigt die Aufsicht auf das zweite Scheibenelement 15, das in Strömungsrichtung gesehen unmittelbar auf das erste Scheibenelement 12 folgt. Das Scheibenelement 15, also das feststehende Scheibenelement, weist eine erste Öffnung 21 auf, die sich über fast einen gesamten Umfang erstreckt und die in der Aufsicht gesehen vollständig in dem Zwischenraum zwischen den beiden Zylindern 16, 17 liegt. Über den Umfang gesehen nimmt die in radialer Richtung gemessene Breite dieser Öffnung 21 im Gegenuhrzeigersinn der Fig. 3 kontinuierlich ab.3 shows the top view of the second disc element 15, seen in the direction of flow directly on the first Disk element 12 follows. The disc element 15, that is fixed disc element, has a first opening 21 which extends over almost an entire circumference and those seen from above completely in the space lies between the two cylinders 16, 17. About the scope seen the width measured in the radial direction takes this Opening 21 in the counterclockwise direction of FIG. 3 continuously from.

Das feststehende Scheibenelement 15 weist eine zweite Öffnung 22 auf, die sich ebenfalls in Umfangsrichtung erstreckt und die vollständig innerhalb des inneren Zylinders 17 angeordnet ist. Auch diese zweite Öffnung nimmt in radialer Richtung gemessen in ihrer Breite kontinuierlich ab, und zwar in umgekehrtem Drehsinn gegenüber der Öffnung 21 des Scheibenelementes 15.The fixed disc element 15 has a second opening 22, which also extends in the circumferential direction and which are arranged entirely within the inner cylinder 17 is. This second opening also takes measured in the radial direction continuously decreasing in width, in reverse Direction of rotation relative to the opening 21 of the disc element 15.

In jeder beliebigen Position des verdrehbaren Scheibenelementes 12 innerhalb des Brausekopfes kann das Wasser nur durch die Öffnung 20 zu den Öffnungen 21 und 22 fließen. Da die beiden Scheibenelemente 12, 15 mindestens im Bereich der Öffnungen dicht aneinander anliegen, wird der Öffnungsquerschnitt durch den Überdeckungsbereich zwischen der Öffnung 20 und der Öffnung 21 bzw. zwischen der Öffnung 20 und der Öffnung 22 bestimmt. Man kann erkennen, daß je nach Stellung des Scheibenelementes 12 die Breite der Überdeckung verschieden ist. Der wirksame Querschnitt wird auf diese Weise abhängig von der Winkelposition der verdrehbaren Scheibe 12 gegenüber der feststehenden Scheibe 15. Bei einem kontinuierlichen Umlaufen des drehbaren Scheibenelementes 12 gegenüber dem feststehenden Scheibenelement 15 verringert sich also beispielsweise die Menge des zwischen den Zylindern 16 und 17 strömenden Wassers, während sich die Menge des durch den inneren Zylinder strömenden Wassers kontinuierlich vergrößert.In any position of the rotatable disc element 12 within the shower head, the water can only flow through the opening 20 to the openings 21 and 22. There the two disc elements 12, 15 at least in the area of Openings lie close together, the opening cross-section through the overlap area between the opening 20 and the opening 21 or between the opening 20 and the opening 22 determined. One can see that depending on the position the width of the overlap of the disc element 12 is. The effective cross-section is dependent in this way from the angular position of the rotatable disc 12 opposite the fixed disc 15. With a continuous Rotating the rotatable disc member 12 relative to the fixed disc element 15 is thus reduced, for example the amount of between cylinders 16 and 17 flowing water while the amount of water flowing through the inner Cylinder of flowing water continuously increased.

Nimmt man an, daß die Scheibe in der Aufsicht der Fig. 2 sich im Gegenuhrzeigersinn dreht, so verringert sich das durch den Ringraum zwischen den Zylindern 16, 17 fließende Wasser kontinuierlich bis auf Null und springt dann wieder auf vollen Wert. Das durch den inneren Zylinder 17 fließende Wasser nimmt kontinuierlich zu, bis es ein Maximum erreicht, worauf es dann wieder ruckartig auf Null zurückgeht.Assuming that the disc in the supervision of FIG. 2 is rotates counterclockwise, this is reduced by the Annulus between the cylinders 16, 17 flowing water continuously to zero and then jumps back to full Value. The water flowing through the inner cylinder 17 increases continuously until it reaches a maximum, whereupon then it suddenly goes back to zero.

Durch Änderung der Form der Öffnungen 21, 22 und ggf. auch der Öffnung 20 können auch unterschiedliche Muster der Verringerung und Vergrößerung der Menge des aus den beiden Gruppen von Strahlaustrittsöffnungen austretenden Wassers bewirkt werden.By changing the shape of the openings 21, 22 and possibly also opening 20 may also have different patterns of reduction and increasing the amount of the two Groups of water outlet jets be effected.

Je nach Ausbildung der Scheiben sind auch Umstellungen bzw. Variationen von mehreren Strahlarten möglich.Depending on the design of the panes, changes or Variations of several jet types possible.

Um eine bevorzugte Strahlart oder Strahlartkombination festzuhalten, ist eine Arretierungseinrichtung vorgesehen, mit der der Stellmotor bzw. Turbine angehalten werden kann. Eine Bremsung zur Variation der Verstellgeschwindigkeit kann mit dieser Einrichtung ebenso vorgenommen werden.To record a preferred spray type or combination, a locking device is provided with which the actuator or turbine can be stopped. A Braking to vary the adjustment speed can be done with this facility can also be made.
