Description

Die Erfindung betrifft einen Brausekopf gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a shower head according to the preamble of patent claim 1.

Häüfig werden bei Kopf- oder Handbrausen am Brauseboden unterschiedliche Strahlaustrittsöffnungen vorgesehen, um unterschiedliche Strahlbilder oder Strahlarten zu erzeugen. Um von einer Strahlart zur anderen zu wechseln ist eine Vielzahl von Umstelleinrichtungen bekannt.It is common for head or hand showers on the shower base to have different jet outlet openings in order to produce different jet patterns or jet types. To change from one type of jet to another, a plurality of switching devices is known.

Aus der DE 41 16 929 A1 ist eine Handbrause für Dusch- und Badeeinrichtungen mit einem Wasserzuführungskanal und einem drehbar an dem Wasserzuführungskanal angeordneten Brausekopf bekannt. Der Brausekopf weist eine Dichtscheibe mit mehreren Öffnungen und mehrere Brausestrahlen erzeugende Strahldüsen auf, die durch Drehen des Brausekopfs um seine Längsachse wahlweise an den Wasserzuführungskanal anschließbar sind.From the DE 41 16 929 A1 a hand shower for shower and bath facilities with a water supply channel and a rotatable arranged on the water supply channel shower head is known. The shower head has a sealing disc with a plurality of openings and several spray jets generating jet nozzles, which can be connected by turning the shower head about its longitudinal axis optionally to the water supply channel.

Da der Brausekopf dabei grundsätzlich gegen die an der Dichtscheibe vorgesehenen Dichtmittel verdreht wird, kann es gerade bei Schwergängigkeit des Brausekopfes zum Verschleiß dieser Dichtmittel kommen, wodurch der Brausekopf undicht werden kann.Since the shower head is basically rotated against the provided on the sealing gasket sealant, it can just come with difficulty of the shower head to wear this sealant, causing the shower head can be leaking.

Aus der US 5 937 905 A ist ein Brausekopf mit zwei Wasserführungen, zwei unterschiedlichen Strahlbildnern und einer Umstelleinrichtung in Form eines Kippschalters, der starr mit federbelasteten Einzelventilen verbunden ist, vorgesehen, so dass durch Hinunterdrücken des einen Ventils jeweils das andere Ventil angehoben und somit die Wasserführung zu einem Strahlbild freigegeben wird.From the US 5,937,905 A is a shower head with two water channels, two different jet formers and a changeover in the form of a toggle switch, which is rigidly connected to spring-loaded individual valves, provided so that by depressing the one valve each raised the other valve and thus the water flow is released to a spray pattern.

Aus der EP 0 732 148 A2 ist zudem eine Mehrfunktions-Handbrause bekannt, deren unterschiedliche Strahlarten über ein verschiebliches Ventilelement realisiert werden. Das Ventilelement umfasst einen Doppelventilkegel, eine Anschlagstange und mehrere Federelementen und wird über einen Schieber mit Ausleger und Führungsschlitzen, der wiederum über eine Wippe bedient wird, angesteuert.From the EP 0 732 148 A2 In addition, a multi-function hand shower is known, the different spray modes are realized via a sliding valve element. The valve element comprises a shuttle, a stop rod and a plurality of spring elements and is controlled by a slider with boom and guide slots, which in turn is operated by a rocker.

Weiterhin zeigen die DE 29 19 734 B1 und die EP 1 616 628 A1 Brauseköpfe mit zwei Strahlarten, bei denen je nach Position des verschieblichen Ventilelements die eine oder andere Ventilöffnung und damit der Zufluss zu den jeweiligen Austrittsöffnungen freigegeben wird.Furthermore, the show DE 29 19 734 B1 and the EP 1 616 628 A1 Shower heads with two spray modes in which, depending on the position of the displaceable valve element, one or the other valve opening and thus the inflow to the respective outlet openings is released.

Vor diesem Hintergrund besteht die Aufgabe der Erfindung darin, einen Brausekopf zu verbessern.Against this background, the object of the invention is to improve a shower head.

Die Aufgabe wird durch einen Brausekopf mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind Gegenstand von Unteransprüchen.The object is achieved by a shower head with the features of claim 1. Advantageous developments are the subject of dependent claims.

Mit der Erfindung wird ein Brausekopf bereitgestellt, der ein Gehäuse mit einem Wassereinlass, wenigstens einer Wasserführung und einem Gehäuseboden, in welchem Strahlaustrittsöffnungen angeordnet sind, aufweist. Die Wasserführung dient dabei als Verbindung zwischen Wassereinlass und einer Anzahl von Strahlaustrittsöffnungen. Weiterhin ist für die Wasserführung ein Ventilelement zur Abdichtung einer Ventilöffnung vorgesehen. Gemäß der Erfindung ist das Ventilelement beidseitig verschieblich gelagert. Dies bedeutet, dass nur eine radiale Lagerung oder Führung des Ventilelements vorgesehen ist, so dass dieses in der Wirkrichtung des Ventils bzw. in Richtung des Ventilhubs um einen Weg (x) frei bewegbar ist. Zur Betätigung des Ventilelements ist eine Steuereinrichtung mit mindestens einem auf das Ventilelement wirkenden Steuerelement vorgesehen, das eine Verschiebung des Ventilelements um einen Ventilhub (y) definiert. Die bewegliche Steuereinrichtung ist als separates Bauteil, das lediglich in Wirkverbindung mit dem Ventilelement steht, vorgesehen. Eine mechanische Anbindung der Steuereinrichtung an das Ventilelement wird hierbei vermieden. Die bewegliche Steuereinrichtung kann im Gehäuse zwischen Wassereinlass und Gehäuseboden angeordnet sein.With the invention, a shower head is provided, which has a housing with a water inlet, at least one water guide and a housing bottom, in which jet outlet openings are arranged. The water guide serves as a connection between the water inlet and a number of jet outlet openings. Furthermore, a valve element for sealing a valve opening is provided for the water supply. According to the invention, the valve element is mounted displaceably on both sides. This means that only a radial bearing or guidance of the valve element is provided, so that it is freely movable in the direction of action of the valve or in the direction of the valve lift by a distance (x). For actuating the valve element, a control device is provided with at least one control element acting on the valve element, which defines a displacement of the valve element by a valve lift (y). The movable control device is provided as a separate component which is only in operative connection with the valve element. A mechanical connection of the control device to the valve element is thereby avoided. The movable control device can be arranged in the housing between the water inlet and the housing bottom.

Zur Erzeugung unterschiedlicher Strahlbilder kann der Gehäuseboden mehrere Arten von Strahlaustrittsöffnungen besitzen. Bei unterschiedlichen Arten von Strahlaustrittsöffnungen ist üblicherweise jeder Art von Strahlaustrittsöffnungen eine Wasserführung zugeordnet. In diesem Fall ist pro Wasserführung ein Ventilelement vorgesehen.To produce different jet patterns, the housing bottom can have several types of jet outlet openings. In the case of different types of jet outlet openings, each type of jet outlet opening is usually associated with a water guide. In this case, a valve element is provided per water supply.

Alternativ dazu kann auch nur eine Art oder Form von Strahlaustrittsöffnungen vorgesehen sein, deren Strahlbild über die Bedienung der Steuereinrichtung veränderbar ist. Auch in diesem Fall können mehrere Wasserführungen angeordnet sein, die jeweils mit einer Anzahl derselben Strahlaustrittsöffnungen verbunden sind. Für jede Wasserführung ist wiederum ein Ventilelement angeordnet.Alternatively, only one type or form of jet outlet openings can be provided, the jet pattern of which can be changed via the operation of the control device. Also in this case, a plurality of water guides can be arranged, which are each connected to a number of the same jet outlet openings. For each water guide, in turn, a valve element is arranged.

Bei dem erfindungsgemäßen Brausekopf wird in Abhängigkeit von der Position des Steuerelements jeweils eine Ventilöffnung von dem Ventilelement ganz oder teilweise freigegeben oder verschlossen. Dies wird von der Anordnung des Steuerelements auf der Steuereinrichtung und von dessen Form und Höhe bestimmt. Die Steuereinrichtung kann daher als reine Umstelleinrichtung zwischen zwei oder mehreren Strahlbildern vorgesehen sein, indem nämlich eine oder mehrere Wasserführungen freigegeben oder verschlossen werden. Weiterhin kann sie als Drossel- und/ oder Absperreinrichtung verwendet werden. Falls mit der Steuereinrichtung nur der Wasserzufluss gedrosselt werden soll, ist der Ventilhub (y) so definiert, dass das Ventilelement zwar vom Ventilsitz abhebt aber nicht die gesamte Ventilöffnung freigibt. Mit einer derartigen Einstellung kann beispielsweise ein Wassersparmodus an der Brause realisiert werden.In the shower head according to the invention in each case a valve opening of the valve element is fully or partially released or closed depending on the position of the control. This is determined by the arrangement of the control on the controller and by its shape and height. The control device can therefore be provided as a pure switching device between two or more jet images, namely by releasing or closing one or more water guides. Furthermore, it can be used as a throttling and / or shut-off device. If only the water flow is to be throttled with the control device, the valve lift (y) is defined so that the valve element lifts off the valve seat but does not release the entire valve opening. With such a setting, for example, a water-saving mode can be realized on the shower.

Vorteilhafterweise sind das oder die Ventilelemente in ihrer Schließstellung jeweils durch Wasserdruck und/oder ein Federelement beaufschlagt. Bei der Bedienung des Ventilelements über die Steuereinrichtung wird somit das Ventilelement gegen eine Federkraft oder gegen eine durch anstehenden Wasserdruck im Brausekopf erzeugte Kraft um den Ventilhub (y) aus dem Ventilsitz gehoben. Falls ein Federelement an dem Ventilelement angeordnet ist und die Steuereinrichtung weiterbewegt wird, so dass das Steuerelement nicht mehr auf das Ventilelement wirkt, kehrt es somit wieder in seine Schließstellung zurück.Advantageously, the valve element or elements are acted upon in their closed position in each case by water pressure and / or a spring element. When the valve element is operated via the control device, the valve element is thus lifted out of the valve seat against a spring force or against a force generated by the pending water pressure in the shower head by the valve lift (y). If a spring element is arranged on the valve element and the control device is moved further, so that the control element no longer acts on the valve element, it thus returns to its closed position.

Falls das Ventilelement nur durch anstehenden Wasserdruck gegen den Ventilsitz gedrückt wird, ist es nach Absperren des Wassers an einer zugehörigen Sanitärarmatur wieder frei verschieblich.If the valve element is pressed only by pending water pressure against the valve seat, it is again freely displaceable after shutting off the water to an associated sanitary fitting.

Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, dass zusätzlich ein Ventilelement für Luftzufuhr im Brausekopf vorgesehen ist. Neben den Wasserführungen ist dementsprechend ein Kanal für Luft im Gehäuse des Brausekopfes vorgesehen. Die Luft wird mittels eines Venturieffekts von außen angesaugt. Um die Luft in der Wasserführung oder einer Mischkammer mit Wasser vermischen zu können, ist daher ein weiteres Ventilelement für die angesaugte Luft im Brausekopf vorgesehen. Dieses Ventilelement kann baugleich zu den Ventilelementen für die Wasserführungen ausgeführt sein. Durch die Beimischung von Luft kann neben der Erzeugung unterschiedlicher Strahlbilder auch ein weiterer Wassersparmodus vorgesehen werden.An advantageous embodiment of the invention provides that in addition a valve element for air supply is provided in the shower head. In addition to the water ducts a channel for air in the housing of the shower head is accordingly provided. The air is sucked in from outside by means of a venturi effect. In order to mix the air in the water flow or a mixing chamber with water, therefore, a further valve element for the sucked air is provided in the shower head. This valve element can be constructed identical to the valve elements for the water guides. The addition of air, in addition to the generation of different jet images and a further water-saving mode can be provided.

Weiterhin kann mit der Steuereinrichtung jedes Ventilelement einzeln oder in Kombination mit wenigstens einem anderen Ventilelement angesteuert werden. Dies wird durch die Anordnung des oder der Steuerelemente erreicht.Furthermore, with the control device each valve element can be controlled individually or in combination with at least one other valve element. This is achieved by the arrangement of the one or more controls.

Hierzu können pro Ventilelement mehr als ein Steuerelement vorgesehen sein, die bei Betätigung der Steuereinrichtung nacheinander auf dasselbe Ventilelement wirken. Alternativ dazu kann ein Steuerelement für mehrere Ventilelemente vorgesehen sein. Im letztgenannten Fall wirkt bei der Bewegung der Steuereinrichtung dasselbe Steuerelement nacheinander auf mehrere Ventilelemente ein. Dabei können die Ventilelemente in Reihe oder versetzt zueinander angeordnet sein.For this purpose, more than one control element can be provided per valve element, which act successively on actuation of the control device on the same valve element. Alternatively, a control for a plurality of valve elements may be provided. In the latter case, during the movement of the control device, the same control element acts successively on a plurality of valve elements. In this case, the valve elements can be arranged in series or offset from one another.

Gemäß einer Ausgestaltung der Erfindung können das oder die Steuerelemente in Form eines Nockens, eines Stifts, eines Kipphebels oder in Form einer Vertiefung vorgesehen sein.According to one embodiment of the invention, the one or more controls may be provided in the form of a cam, a pin, a rocker arm or in the form of a recess.

Um eine definierte Hubbewegung des Ventilelements zu bewirken, muss das Steuerelement der Steuereinrichtung direkt unter das Ventilelement gelangen. Hierbei ist für den Nutzer lediglich die Kraft eines Federelements oder die Kraft des auf das Ventilelement wirkenden Wasserdrucks zu überwinden. Hierbei ist es von Vorteil, wenn das Steuerelement oder die Steuerelemente Schrägen, Kurven- oder Führungsbahnen zur stufenlosen Einstellung des Ventilhubs aufweisen. Aufgrund der Schrägen wird es für den Nutzer noch einfacher, die Steuereinrichtung zu bedienen, da keine Widerstände in Form von Versätzen überwunden werden müssen. Über die stufenlose Einstellung des Ventilhubs und die zuvor beschriebene Drosselfunktion der Steuereinrichtung sind somit pro Strahlbild unterschiedliche Durchflussmengen einstellbar.In order to effect a defined lifting movement of the valve element, the control of the control device must pass directly under the valve element. In this case, the user only has to overcome the force of a spring element or the force of the water pressure acting on the valve element. It is advantageous if the control or the controls have slopes, curves or tracks for continuous adjustment of the valve lift. Due to the bevels, it becomes even easier for the user to operate the control device, since no resistances in the form of offsets have to be overcome. As a result of the stepless adjustment of the valve lift and the previously described throttling function of the control device, different flow rates can be set per spray pattern.

Eine Ausgestaltung der Erfindung sieht vor, dass als Steuereinrichtung eine Scheibe und als Steuerelement ein senkrecht zur Scheibenebene angeordnetes Steuerelement vorgesehen ist. Hierbei kann die Scheibe um eine senkrecht zum Gehäuseboden angeordnete oder um eine parallel zur Ventilelementachse angeordnete Achse drehbar sein. Auf der Scheibe können ein oder mehrere Steuerelemente angeordnet sein. Bei der Anordnung mehrerer Steuerelemente in radialer und/oder tangentialer Richtung ergeben sich für die zugehörigen Ventilelemente eine Vielzahl von Variationsmöglichkeiten für deren Einstellbarkeit.An embodiment of the invention provides that a disc is provided as a control device and a control arranged perpendicular to the disc plane control. In this case, the disk may be rotatable about an axis arranged perpendicular to the housing bottom or about an axis parallel to the valve element axis. One or more controls may be located on the disk. In the arrangement of a plurality of control elements in the radial and / or tangential direction, a large number of possible variations for their adjustability results for the associated valve elements.

Eine weitere Ausgestaltung der Erfindung sieht vor, dass als Steuereinrichtung eine translatorisch verschiebliche Scheibe vorgesehen ist. Auch hier sind die Steuerelemente senkrecht zur Scheibenebene angeordnet. Alternativ dazu können die Ventilelemente nicht nur senkrecht, sondern auch waagerecht oder unter einer Neigung im Brausekopf angeordnet sein. Bei waagerecht angeordneten Ventilelementen kann als Steuereinrichtung ein Kreisring oder ein zylindrisches Element vorgesehen werden. Die Steuerelemente sind dann radial nach innen oder außen gerichtet und wirken ebenfalls in Hubrichtung des Ventilelements auf diese ein.A further embodiment of the invention provides that a translationally displaceable disk is provided as the control device. Again, the controls are arranged perpendicular to the disk plane. Alternatively, the valve elements may not only be vertical, but also be arranged horizontally or under an inclination in the shower head. In the case of horizontally arranged valve elements, a circular ring or a cylindrical element can be provided as a control device. The controls are then directed radially inward or outward and also act in the stroke direction of the valve element on this.

Gemäß einer weiteren Ausführungsform der Erfindung kann als Steuereinrichtung auch eine Nockenwelle vorgesehen sein.According to a further embodiment of the invention may be provided as a control device and a camshaft.

Figur 1 zeigt eine Ansicht einer Handbrause. Die Handbrause umfasst einen Griff und einen Brausekopf, die einstückig miteinander verbunden sind. Figur 2 zeigt einen teilweisen Schnitt durch den Brausekopf der Handbrause entlang der Linie II-II. Figur 3 zeigt einen teilweisen Schnitt durch den Brausekopf der Handbrause entlang der Linie III-III. Der Brausekopf umfasst ein Gehäuse 1, das mit einem Griffgehäuse verbunden ist. Das Gehäuse 1 des Brausekopfs ist mit einem Gehäuseboden 4 verbunden, in welchem Strahlaustrittsöffnungen 44 angeordnet sind. Im vorliegenden Fall weist die Handbrause nur eine Art von Strahlaustrittsöffnungen 4.4 auf. Der Gehäuseboden 4, der auch Strahlbildner oder Brauseboden genannt wird, besteht aus mehreren Einzelteilen 41, 42, 43, die zu einer Baugruppe zusammengefasst sind. Das abschließende Teil des Gehäusebodens 4 wird von einer harten Außenschale 41 gebildet, die zur Stabilisierung und Formgebung einer weichen Silikonmatte 42 dient, an der Strahlaustrittsdüsen angeformt sind. Die Strahlaustrittsdüsen, die durch Öffnungen in der Außenschale 41 hindurch treten, weisen wiederum die Strahlaustrittsöffnungen 44 auf. Im Innenbereich des Brausekopfes schließt der Gehäuseboden 4 mit einer Rückwand 43 ab, so dass zwischen der Außenschale 41 und der Rückwand 43 eine Wasserverteilkammer 12 gebildet wird. Über die Wasserverteilkammer 12 werden die jeweils mit dieser verbundenen Strahlaustrittsöffnungen 44 gleichmäßig mit Wasser versorgt. Weiterhin ist im Gehäuse 1 wenigstens eine Öffnung zum Ansaugen von Luft in den Brausekopf vorgesehen. Zudem weist der Brausekopf einen Luftansaugkanal 6 auf, der in einen Luftkanal 5 mündet. Im vorliegenden Beispiel ist der Luftkanal 5 als separater Kanal innerhalb der Wasserführung 3 angeordnet. FIG. 1 shows a view of a hand shower. The hand shower includes a handle and a shower head, which are integrally connected. FIG. 2 shows a partial section through the shower head of the hand shower along the line II-II. FIG. 3 shows a partial section through the shower head of the hand shower along the line III-III. The shower head comprises a housing 1, which is connected to a handle housing. The housing 1 of the shower head is connected to a housing bottom 4, in which jet outlet openings 44 are arranged. In the present case, the hand shower only one type of jet outlet openings 4.4. The housing bottom 4, which is also called jet former or shower base, consists of several individual parts 41, 42, 43, which are combined to form an assembly. The final part of the housing bottom 4 is formed by a hard outer shell 41, which is used for stabilizing and shaping a soft silicone mat 42 serves, are formed on the jet outlet nozzles. The jet outlet nozzles, which pass through openings in the outer shell 41, again have the jet outlet openings 44. In the interior of the shower head, the housing bottom 4 terminates with a rear wall 43, so that a water distribution chamber 12 is formed between the outer shell 41 and the rear wall 43. Via the water distribution chamber 12, the respectively associated with this jet outlet openings 44 are supplied evenly with water. Furthermore, at least one opening for sucking air into the shower head is provided in the housing 1. In addition, the shower head on an air intake duct 6, which opens into an air duct 5. In the present example, the air channel 5 is arranged as a separate channel within the water guide 3.

Das Wasser gelangt durch einen Wassereinlass 10 über eine Wasserführung 2, 3 in den Brausekopf. Im vorliegenden Ausführungsbeispiel besteht die Wasserführung 2, 3 aus einer Griffwasserführung und einer Kopfwasserführung, die lösbar miteinander verrastet sind. In der Wasserführung 3, hier der Kopfwasserführung, ist eine Ventilöffnung 31 mit einem entsprechenden Ventilsitz 32 für ein Ventilelement 8 angeordnet. Das Ventilelement 8 umfasst einen Ventilschaft und einen Ventilschließkörper, der in der Schließstellung am Ventilsitz 32 anliegt.The water passes through a water inlet 10 via a water guide 2, 3 in the shower head. In the present embodiment, the water guide 2, 3 consists of a handle water guide and a head water guide, which are releasably locked together. In the water guide 3, here the top water guide, a valve opening 31 is arranged with a corresponding valve seat 32 for a valve element 8. The valve element 8 comprises a valve stem and a valve closing body, which rests against the valve seat 32 in the closed position.

Im vorliegenden Fall weist das Ventilelement 8 auch ein elastisches Kopfstück auf, das als Federelement wirkt. Das Ventilelement 8 kann sich ohne anstehendes Wasser in der Wasserführung 3 in seiner Wirkrichtung um einen durch den Federweg des Federelements bestimmten Ventilweg (x) hin und her bewegen. Wenn Wasser durch den Wassereinlass 10 zur Wasserführung 3 gelangt, wirkt der Wasserdruck zusätzlich zu dem Federelement auf das Ventilelement 8 und drückt es in seine Schließposition gegen den Ventilsitz 32. Zusätzlich zu dem ersten Ventilelement 8 ist ein weiteres Ventilelement 7 angeordnet, dessen Ventilsitz 33 sich zwischen Luftkanal 5 und Außenseite der Wasserführung 3 befindet. Über das Ventilelement 7 wird somit nur die Luftzufuhr in die Wasserführung 3 gesteuert. Die durch die Ventilöffnung 34 einströmende Luft gelangt mit dem über die Ventilöffnung 31 zuströmenden Wasser ebenfalls in die Wasserverteilkammer 12, die somit auch als Mischkammer dient.In the present case, the valve element 8 also has an elastic head piece, which acts as a spring element. The valve element 8 can move without water in the water guide 3 in its direction of action by a certain by the spring travel of the spring element valve travel (x) back and forth. When water passes through the water inlet 10 to the water guide 3, the water pressure acts in addition to the spring element on the valve element 8 and pushes it into its closed position against the valve seat 32. In addition to the first valve element 8, a further valve element 7 is arranged, the valve seat 33 itself between the air duct 5 and the outside of the water guide 3 is located. Via the valve element 7 thus only the air supply is controlled in the water supply 3. The air flowing in through the valve opening 34 also passes into the water distribution chamber 12 with the water flowing in via the valve opening 31, which thus also serves as a mixing chamber.

Zwischen Strahlbildner 4 und dem unteren Ende des Ventilelements 8 ist eine Steuereinrichtung 9 in Form einer Kreisscheibe angeordnet. Diese ist drehbar um die Mittelachse 11 des Brausekopfs gelagert. Die Steuereinrichtung kann mit einem an ihr angeformten Hebel 91 in beide Drehrichtungen betätigt werden.Between jet former 4 and the lower end of the valve element 8, a control device 9 in the form of a circular disk is arranged. This is rotatably mounted about the central axis 11 of the shower head. The control device can be actuated with a molded-on lever 91 in both directions of rotation.

Aus Figur 4 wird sichtbar, dass die Steuereinrichtung 9 mehrere unterschiedlich geformte Steuerelemente 92, 93, 94, 95 aufweist. Diese sind sowohl in axialer als auch in radialer Richtung versetzt zueinander angeordnet. Über Wasserdurchtrittsöffnungen 97 gelangt das Wasser bei freigegebener Ventilöffnung 31 von der Wasserführung 3 in die Wasserverteilkammer 12.Out FIG. 4 It can be seen that the control device 9 has a plurality of differently shaped control elements 92, 93, 94, 95. These are both axial and radial Direction offset from each other. Via water passage openings 97, the water, with the valve opening 31 released, passes from the water guide 3 into the water distribution chamber 12.

Über die Position der Steuereinrichtung 9 und der an dieser angeformten Steuerelemente 92, 93, 94, 95 können nun die Ventilpositionen der Ventilelemente 7 und 8 gesteuert werden. Eine Gruppe von Steuerelementen 92, 93, 94 liegen auf einer Kreisbahn und wirken bei einer Drehung der Steuereinrichtung auf das Ventilelement 8. Ein weiteres Steuerelement 95 ist in radialer Richtung versetzt zu den übrigen Steuerelementen 92, 93, 94 angeordnet und zur Betätigung des Ventilelements 7 vorgesehen.By means of the position of the control device 9 and the controls 92, 93, 94, 95 molded onto it, the valve positions of the valve elements 7 and 8 can now be controlled. A group of control elements 92, 93, 94 lie on a circular path and act on a rotation of the control device on the valve element 8. A further control element 95 is arranged in the radial direction offset from the other control elements 92, 93, 94 and for actuating the valve element. 7 intended.

Sobald die Steuereinrichtung derart positioniert ist, dass kein Steuerelement auf das Ventilelement 8 wirkt, befindet sich das Ventil in der Schließstellung und es tritt trotz anstehenden Wasserdrucks in der Wasserführung 3 kein Wasser aus dem Gehäuseboden 4 aus.As soon as the control device is positioned in such a way that no control acts on the valve element 8, the valve is in the closed position and, despite the water pressure in the water guide 3, no water will escape from the housing bottom 4.

Wird die Steuereinrichtung 9 dagegen so verdreht, dass beispielsweise das Steuerelement 93 von unten gegen das Ventilelement 8 drückt und dieses somit gegen den anstehenden Wasserdruck und gegen die Federkraft des elastischen Elements aus dem Ventilsitz 32 hebt, wird die Ventilöffnung 31 zumindest so weit freigegeben, dass eine bestimmte Durchflussmenge in die Wasserverteilkammer 12 und somit weiter zu den Strahlaustrittsöffnungen 44 gelangt. Wie aus den Fig. 3 und Fig. 4 deutlich wird, ist der Ventilhub (y) dabei abhängig von dem auf das zugehörige Ventilelement wirkende Steuerelement. Hierdurch kann der Ventilhub (y) eines Ventilelements 7, 8 variabel vorgesehen werden.On the other hand, if the control device 9 is rotated in such a way that, for example, the control 93 presses against the valve element 8 from below and lifts it out of the valve seat 32 against the upcoming water pressure and against the spring force of the elastic element, the valve opening 31 is released at least so far that a certain flow rate in the water distribution chamber 12 and thus further reaches the jet outlet openings 44. Like from the Fig. 3 and Fig. 4 becomes clear, the valve lift (y) is dependent on the control element acting on the associated valve element. As a result, the valve lift (y) of a valve element 7, 8 can be variably provided.

Bei weiterem Verdrehen der Steuereinrichtung 9 wird zunächst wieder eine Absperrstellung erreicht bevor beispielsweise gleichzeitig das Steuerelement 95 auf das Ventilelement 7 und das Steuerelement 92 auf das Ventilelement 8 wirkt.Upon further rotation of the control device 9, a shut-off position is first again achieved before, for example, the control element 95 simultaneously acts on the valve element 7 and the control element 92 on the valve element 8.

In diesem Fall werden sowohl die Ventilöffnungen 31 und 34 geöffnet, so dass sowohl Luft als auch Wasser in die Wasserverteilkammer 12 gelangen und dort vermischt werden. Aus den Strahlaustrittsöffnungen 44 treten somit belüftete Brausestrahlen aus, die ein anderes Strahlbild aufweisen als Brausestrahlen ohne Luftanteil.In this case, both the valve openings 31 and 34 are opened, so that both air and water enter the water distribution chamber 12 and are mixed there. From the jet outlet openings 44 thus emerge ventilated spray jets, which have a different spray pattern than effervescent jets without air.

Bei Anordnung mehrerer getrennter Wasserführungen und zugehörigen Stahlaustrittsöffnungen vermehrt sich die Anzahl der Varianten bezüglich der Ansteuerung und Kombination der zugehörigen Ventilelemente, so dass eine Vielzahl von Effekten erzielt werden kann.In the arrangement of several separate water ducts and associated steel outlet openings increases the number of variants with respect to the control and combination of the associated valve elements, so that a variety of effects can be achieved.
