Die Erfindung betrifft einen Duschkopf für eine Duschbrause mit

  1. a) einem gehäuseartigen ersten Teil, in dem ein Wasserführungskanal verläuft, der an einem ersten Ende mit einer Wasserzulauföffnung kommuniziert;
  2. b) einem mit dem ersten Teil verbundenen zweiten Teil, das als Auslaufelement ausgebildet ist, dessen Aufnahmeraum in mindestens einer Funktionsart des Duschkopfes mit einem zweiten Ende des Wasserführungskanals kommuniziert und dessen Außenrand in dieser Funktionsart in einem Bereich eine Überlaufkante bildet, über welche Wasser abströmen kann;
    wobei

The invention relates to a shower head for a shower with
  1. a) a box-like first part, in which a water supply channel extends, which communicates at a first end with a water inlet opening;
  2. b) a second part connected to the first part, which is designed as a discharge element whose receiving space communicates in at least one mode of operation of the shower head with a second end of the water guide channel and the outer edge forms in this type of function in an area an overflow edge, can flow through which water ;
    in which
  3. c) the second part also has a plurality of nozzle-like outlet openings which, at least in a second type of operation of the shower head, communicate with the second end of the water-guiding channel and through which a plurality of effervescent jets can then emerge.

In jüngster Zeit haben Duschköpfe eine erhebliche Beliebtheit erlangt, bei denen zumindest in einer Betriebsart das Wasser nicht in einer Vielzahl von Einzelstrahlen austritt, sondern es möglich ist, eine Art "Wasservorhang" zu erzeugen, der über eine Auslaufkante eines schräggestellten, nach oben offenen Auslaufelements, z. B. einer gekrümmten Auslaufschale, übertritt. Derartige Duschköpfe besitzen nicht nur ein ungewöhnliches, Aufsehen erregendes ästhetisches Gepräge; das Auslaufelement besitzt darüber hinaus eine technische Funktion: Diese besteht darin, das aus dem gehäuseartigen ersten Teil austretende Wasser zunächst auf einer verhältnismäßig großen Fläche zu verteilen und dann so im freien Fall abströmen zu lassen, daß sich der gewünschte, im wesentlichen geschlossene Wasservorhang ergibt. Hierdurch wird in gewisser Weise ein kleiner Wasserfall simuliert, was bei vielen Benutzern ein Gefühl besonderen Wohlbehagens auslöst.Recently shower heads have gained considerable popularity, in which at least in one mode, the water does not escape in a plurality of individual jets, but it is possible to produce a kind of "water curtain", which has a discharge edge of an inclined, upwardly open outlet element , z. B. a curved outlet shell, exceeds. Such shower heads not only have an unusual, eye-catching aesthetic character; Moreover, the outlet element has a technical function: it consists of first distributing the water leaving the box-like first part over a relatively large area and then allowing it to flow out in free fall, resulting in the desired substantially closed curtain of water. As a result, a small waterfall is simulated in some ways, causing many users a sense of well-being.

Ein Duschkopf der eingangs genannten Art, der die Merkmale des Oberbegriffs des Anspruchs 1 aufweist, ist aus der DE 102 19 943 B4 bekannt. Diese beschreibt zwei Ausführungsarten, wie die düsenartigen Auslaßöffnungen angeordnet werden können. Bei den in den Figuren 1 und 2 dargestellten Ausführungsbeispielen befinden sich die düsenartigen Auslaßöffnungen in einem Bereich der Mantelfläche des gehäuseartigen ersten Teils, bei dem in Figur 3 dargestellten Ausführungsbeispiel in einem Durchströmungskörper, der die Auslaufschale durchstößt und einen erheblich kleineren Durchmesser als diese Auslaufschale besitzt. Bei all diesen Ausführungsbeispielen ist die Fläche, über welche die Mehrzahl von düsenartigen Auslaßöffnungen verteilt ist, verhältnismäßig klein. Außerdem ist die Herstellung dieser bekannten Brauseköpfen verhältnismäßig kompliziert.A shower head of the type mentioned, having the features of the preamble of claim 1 is known from DE 102 19 943 B4 known. This describes two embodiments of how the nozzle-like outlet openings can be arranged. In the in the FIGS. 1 and 2 illustrated embodiments, the nozzle-like outlet openings are in a region of the lateral surface of the housing-like first part, in which FIG. 3 illustrated embodiment in a flow body piercing the outlet shell and has a significantly smaller diameter than this outlet shell. In all of these embodiments, the area over which the plurality of nozzle-like outlet openings is distributed is relatively small. In addition, the production of these known shower heads is relatively complicated.

Aufgabe der vorliegenden Erfindung ist es, einen Duschkopf der eingangs genannten Art so auszugestalten, daß die Herstellung vereinfacht und das Strahlbild günstig ist.Object of the present invention is to provide a shower head of the type mentioned in such a way that the production is simplified and the spray pattern is low.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß

  • d) das das Auslaufelement bildende zweite Teil aus einem Oberteil und einem Unterteil gebildet ist, zwischen denen sich mindestens ein Innenraum befindet, der in der zweiten Funktionsart des Duschkopfes mit dem zweiten Ende des Wasserführungskanals kommuniziert;
    wobei
  • e) die düsenartigen Auslaßöffnungen in dem Unterteil angeordnet sind.
This object is achieved in that
  • d) the outlet part forming the second part of an upper part and a lower part is formed, between which there is at least one interior, which communicates in the second mode of operation of the shower head with the second end of the water guide channel;
    in which
  • e) the nozzle-like outlet openings are arranged in the lower part.

Bei der erfindungsgemäßen Ausgestaltung des Duschkopfes wird also das Auslaufelement gewissermaßen "doppelwandig" gemacht und der dadurch entstehende Innenraum wird als Wasserverteilraum genutzt, über den sich das Wasser großflächig ausbreiten und so eine Vielzahl von großflächig verteilten düsenartigen Auslaßöffnungen erreichen kann. Diese Auslaßöffnungen finden sich auf derjenigen Seite des Auslaufelements, die der Seite gegenüberliegt, über welche das Wasser in der ersten Funktionsart als "Wasservorhang" abfließt.In the embodiment of the shower head according to the invention, therefore, the outlet element is effectively made "double-walled" and the resulting interior space is used as a water distribution space over which the water spread over a large area and so can reach a variety of large-area distributed nozzle-like outlet openings. These outlet openings can be found on that side of the outlet element which is opposite to the side over which the water in the first mode of operation drains off as a "water curtain".

Die geschilderte erfindungsgemäße Bauart läßt sich leicht dahingehend abwandeln, daß der Innenraum des zweiten Teiles zwischen Oberteil und Unterteil durch mindestens eine Zwischenwand in mindestens zwei Teilräume unterteilt ist, die unabhängig voneinander mit Wasser beaufschlagbar sind. Auf diese Weise lassen sich unterschiedlichste Strahlbilder erzeugen, da das Wasser jeweils durch unterschiedliche Gruppen von düsenartigen Auslaßöffnungen geleitet werden kann, die jeweils einem der unabhängig beschickbaren Teilräume zugeordnet sind.The described design according to the invention can be easily modified to the effect that the interior of the second part between the upper part and lower part is divided by at least one partition in at least two subspaces, which are independently acted upon by water. In this way, a variety of jet patterns can be generated, since the water can be passed through different groups of nozzle-like outlet openings, which are each assigned to one of the independently loadable subspaces.

Zweckmäßigerweise sind die düsenartigen Auslaßöffnungen in einer elastischen Einlage ausgebildet, die auf der Innenseite des Unterteils angeordnet ist. Hierdurch wird die Gefahr des Verkalkens der düsenartigen Auslaßöffnungen verringert.Appropriately, the nozzle-like outlet openings formed in an elastic insert, which is arranged on the inside of the lower part. As a result, the risk of calcification of the nozzle-like outlet openings is reduced.

Eine besonders günstige Möglichkeit, die Umstellung zwischen verschiedenen Funktionsarten des Duschkopfes zu bewirken, besteht darin, daß das zweite Teil gegenüber dem ersten Teil zwischen mindestens zwei Positionen verstellbar ist, wobei jede dieser Positionen einer Funktionsart des Duschkopfes zugeordnet ist.A particularly favorable possibility to effect the changeover between different types of operation of the shower head, is that the second part relative to the first part between at least two positions is adjustable, each of these positions is associated with a type of function of the shower head.

Der in der Zeichnung dargestellte Brausekopf 1 ist für eine Duschbrause bestimmt und weist ein erstes Teil T1 sowie ein zweites Teil T2 auf. Wie insbesondere den Figuren 3 und 4 zu entnehmen ist, umfasst das erste Teil T1 in einem rohrförmigen Gehäuse 4 ein Wasserführungsrohr 3, das einen Wasserführungskanal 2 bildet. Das Wasserführungsrohr 3 besitzt an einem Ende eine von einem Gewinde 5 umgebene Wasserzulauföffnung, an der eine hier nicht gezeigte Wasserleitung, beispielsweise ein flexibler Schlauch, anzuschließen ist. Über ein Umstellventil V wird das Wasser in weiter unten näher beschriebener Weise dem zweiten Teil T2 zugeführt.The shower head 1 shown in the drawing is for a shower head determines and has a first part T1 and a second part T2. As in particular the Figures 3 and 4 can be seen, the first part T1 comprises in a tubular housing 4, a water supply pipe 3, which forms a water guide channel 2. The water guide tube 3 has at one end a water inlet opening surrounded by a thread 5, to which a water pipe, not shown here, for example a flexible hose, is to be connected. Via a diverter valve V, the water is supplied to the second part T2 in a manner described in more detail below.

Das zweite Teil T2 ist ein Auslaufelement und umfasst eine von oben gesehen konkav gekrümmte Auslaufschale 21, deren genaue Bauweise weiter unten erläutert wird und die an ihrer Unterseite eine Mehrzahl von Auslaßöffnungen A2 besitzt. Diese sind düsenartig ausgebildet und können jeweils in bekannter Weise einen Brausestrahl bilden.The second part T2 is an outlet element and comprises a concave curved outflow tray 21 seen from above, the exact construction will be explained below and has on its underside a plurality of outlet openings A2. These are formed like a nozzle and can each form a shower spray in a known manner.

Das zweite Teil T2 ist aus einem Oberteil 15 und einem Unterteil 16 zusammengesetzt, die jeweils einfache, ebenfalls von oben gesehen konkav gekrümmte, einen gemeinsamen Krümmungsmittelpunkt besitzende Schalen sind. Oberteil 15 und Unterteil 16 sind an ihren äußeren Rändern so miteinander verbunden, daß sich zwischen ihnen ein geschlossener Innenraum 14 bildet, mit dem die Auslaßöffnungen A2 kommunizieren. In diesem Innenraum 14 ist an das Unterteil 16 eine Einlage 17 angelegt, in welcher die Austrittsöffnungen A2 ausgebildet sind. Die Einlage 17 besteht aus gummielastischem Material.The second part T2 is composed of an upper part 15 and a lower part 16, which are each simple, also seen from above concavely, having a common center of curvature owning shells. Upper part 15 and lower part 16 are connected to one another at their outer edges so that a closed interior 14 forms between them, with which the outlet openings A2 communicate. In this interior 14, an insert 17 is applied to the lower part 16, in which the outlet openings A2 are formed. The insert 17 is made of rubber-elastic material.

Das schalenförmige Oberteil 15 besitzt eine Überlaufkante 22 an einem in der Figur 1 rechtsliegenden Bereich ihres radial außenliegenden Rands.The bowl-shaped upper part 15 has an overflow edge 22 at one in the FIG. 1 right-hand area of its radially outer edge.

An das Oberteil 15 ist ein zylindrischer Kragen 35 angeformt, dessen Achse parallel zur Achse des Oberteiles 15 selbst verläuft (Figuren 3 und 4).On the upper part 15, a cylindrical collar 35 is formed, whose axis is parallel to the axis of the upper part 15 itself ( Figures 3 and 4 ).

Auf den Kragen 35 des Oberteils 15 ist von oben ein haubenförmiger Deckel 18 aufgesetzt und mit diesem verrastet. Eine sich nach unten vom radial äußeren Rand des Deckels 18 erstreckende Schürze 36 endet mit ihrem unteren Rand bereichsweise (in den Figuren 3 und 4 rechts) in Abstand von dem schalenförmigen Oberteil 15 und bildet auf diese Weise eine Austrittsöffnung A1, über welche Wasser in noch zu beschreibender Weise aus dem radial innerhalb der Schürze 36 liegenden Raum in den radial außerhalb der Schürze 36 liegenden Raum fließen kann.On the collar 35 of the upper part 15 a hood-shaped cover 18 is placed from above and locked with this. A downwardly extending from the radially outer edge of the lid 18 skirt 36 ends with its lower edge partially (in the Figures 3 and 4 right) at a distance from the bowl-shaped upper part 15 and thus forms an outlet opening A1, through which water in a manner to be described from the lying radially inside the skirt 36 space in the radially outside of the skirt 36 lying space can flow.

Außerdem besitzt der Deckel 18 unterseitig einstückig ein Stützteil 20, das auf einer Achse 24 aufliegt. Diese ist ihrerseits an der Oberseite des Wasserführungsrohres 3 angeformt.In addition, the lid 18 has integrally on the underside a support member 20 which rests on an axis 24. This is in turn formed on the top of the water guide tube 3.

Wie die Figuren 3 und 4 zeigen, weist das zweite Teil T2 eine durchgängige Öffnung 27 auf, in welche das erste Teil T1 von unten eingreift. Die Öffnung 27 ist so bemessen, daß das zweite Teil T2 um die Achse 24 zwischen einer oberen und einer unteren Schwenkposition hin- und her verschwenkbar ist. In Figur 3 ist der zweite Teil T2 in der oberen Schwenkposition gezeigt, in welcher die Überlaufkante 22 etwa in einer horizontalen Ebene liegt. Die Achse der von dem zweiten Teil T2 gebildeten Auslaufschale 21 steht dabei annähernd senkrecht. Mit dem Pfeil 28 ist die Richtung der Schwenkbewegung angedeutet, mit welcher das zweite Teil T2 um die Achse 24 in die in Figur 4 dargestellte untere Schwenkposition bewegt werden kann. Bei dieser Schwenkbewegung wird die Ebene, in welcher die Überlaufkante 22 liegt, gegenüber der Horizontalen geneigt. Die Überlaufkante 22 wird dabei nach unten bewegt, während sich der diametral gegenüberliegende Bereich 29 des Randes der Auslaufschale 21 gemäß Pfeil 30 nach oben bewegt. Der Schwenkwinkel, der zwischen den beiden in den Figuren 3 und 4 dargestellten Schwenkpositionen liegt, ist in geeigneter Weise begrenzt.As the Figures 3 and 4 show, the second part T2 has a continuous opening 27, in which engages the first part T1 from below. The opening 27 is sized so that the second part T2 is pivotable about the axis 24 between an upper and a lower pivot position back and forth. In FIG. 3 the second part T2 is shown in the upper pivot position, in which the overflow edge 22 is located approximately in a horizontal plane. The axis of the outlet shell 21 formed by the second part T2 is approximately perpendicular. With the arrow 28, the direction of the pivoting movement is indicated, with which the second part T2 about the axis 24 in the in FIG. 4 shown lower pivot position can be moved. During this pivoting movement, the plane in which the overflow edge 22 is inclined relative to the horizontal. The overflow edge 22 is thereby moved downward, while the diametrically opposite region 29 of the edge of the outlet shell 21 moves upward in accordance with arrow 30. The swing angle between the two in the Figures 3 and 4 is shown pivoted positions, is suitably limited.

Das Umstellventil V wird durch einen Bereich B1 des ersten Teiles T1 und einen Bereich B2 des zweiten Teiles T2 gebildet.The switching valve V is formed by a region B1 of the first part T1 and a region B2 of the second part T2.

Der Bereich B1 des Teiles T1 besitzt im Querschnitt, wie den Figuren 3 und 4 zu entnehmen ist, etwa die Form einer nicht ganz geschlossenen Ellipse, deren größere Achse unter einem spitzen Winkel zur Vertikalen steht. Er besitzt zwei seitliche Austrittsöffnungen 7, von denen in den Figuren 3 und 4 nur eine, in den Figuren 5 und 6 dagegen beide erkennbar sind. Bei diesen Austrittsöffnungen 7 handelt es sich um kreisrunde Öffnungen, die seitlich aus dem Raum 6 herausführen, der von dem Bereich B1 umschlossen ist und mit dem Wasserführungskanal 2 im Wasserführungsrohr 3 des ersten Teiles T1 kommuniziert. Die Strömungsrichtung durch die Austrittsöffnungen 7 ist somit im wesentlichen rechtwinkling zur Strömungsrichtung im Wasserführungskanal 2.The area B1 of the part T1 has in cross section, as the Figures 3 and 4 it can be seen, for example, the shape of a not quite closed ellipse whose major axis is at an acute angle to the vertical. He has two lateral outlet openings 7, of which in the Figures 3 and 4 only one, in the Figures 5 and 6 while both are recognizable. These outlet openings 7 are circular openings which lead laterally out of the space 6, which is enclosed by the area B1 and communicates with the water guide channel 2 in the water guide tube 3 of the first part T1. The flow direction through the outlet openings 7 is thus substantially at right angles to the flow direction in the water guide channel 2.

Eine der beiden Austrittsöffnungen 7 ist in einer Wand 12 gebildet, die nach Art eines Deckels in eine seitliche Öffnung 13 der Umfangswandung 11 des Bereiches B1 eingesetzt ist. Die andere Austrittsöffnung 7, in den Figuren 5 und 6 die rechte, befindet sich in einer einstückig an die Umfangswand 11 angeformten Seitenwand des Bereiches B1.One of the two outlet openings 7 is formed in a wall 12, which is inserted in the manner of a lid in a lateral opening 13 of the peripheral wall 11 of the region B1. The other outlet opening 7, in the Figures 5 and 6 the right, is located in an integrally formed on the peripheral wall 11 side wall of the area B1.

Befindet sich der zweite Teil T2 des Duschkopfes 1 in der oberen, in den Figuren 3 und 5 dargestellten Schwenkposition, so sind die Austrittsöffnungen 7 des Bereiches B1 jeweils mit einer Eintrittsöffnung 8 des Bereichs B2 des zweiten Teiles T2 in Verbindung, wie dies in Figur 5 gezeigt ist. Diese Eintrittsöffnungen 8 sind in zwei parallel zueinander verlaufenden Kulissen 19 ausgebildet, die an das Unterteil 16 des Zeiten Teils T2 angeformt sind, wie dies den Figuren 5 und 6 zu entnehmen ist. Die Eintrittsöffnungen 8 führen in den bereits erwähnten Innenraum 14 zwischen dem Oberteil 15 und dem Unterteil 16 des zweiten Teiles T2, welcher mit den Auslaßöffnungen A2 kommuniziert. In Ausnehmungen der Kulissen 19 sind gummielastische Dichtungsmittel 10 eingelegt; sie dienen zum Abdichten der Kulissen 19 gegenüber dem Bereich B1 des ersten Teils T1. Sie sind so ausgebildet, daß der Bereich B1 entlang der Innenseite der Kulissen 19 verschiebbar ist.Is the second part T2 of the shower head 1 in the upper, in the Figures 3 and 5 illustrated pivot position, the outlet openings 7 of the area B1 are each in communication with an inlet opening 8 of the area B2 of the second part T2, as in FIG. 5 is shown. These inlet openings 8 are formed in two mutually parallel scenes 19, which are integrally formed on the lower part 16 of the times part T2, as the Figures 5 and 6 can be seen. The inlet openings 8 lead into the already mentioned interior 14 between the upper part 15 and the lower part 16 of the second part T2, which communicates with the outlet openings A2. In recesses of the scenes 19 rubber-elastic sealing means 10 are inserted; they serve to seal the scenes 19 with respect to the area B1 of the first part T1. They are designed so that the area B1 along the inside of the scenes 19 is displaced.

Befindet sich das zweite Teil T2 in der in den Figuren 3 und 5 gezeigten oberen Schwenkposition und strömt durch den Wasserzuführungskanal 2 in Richtung des Pfeiles 25 Wasser zu, so gelangt dieses in den Raum 6 innerhalb des Bereiches B1 und von diesem durch die Öffnungen 7 und 8 in den Innenraum 14 der Auslaufschale 21 und tritt schließlich als Brausestrahl durch die Auslaßöffnungen A2 nach unten aus.Is the second part T2 in the in Figures 3 and 5 shown upper pivot position and flows through the water supply channel 2 in the direction of arrow 25 to water, it passes into the space 6 within the range B1 and from there through the openings 7 and 8 in the interior 14 of the outlet shell 21 and finally occurs as a shower jet the outlet openings A2 down.

In den Kulissen 19 sind, wie den Figuren 5 und 6 zu entnehmen ist, oberhalb der Eintrittsöffnungen 8 zwei weitere Eintrittsöffnungen 9 ausgebildet, welche bei der in den Figuren 3 und 5 dargestellten Schwenkposition des Duschkopfes 1 durch den Bereich B1 des Teiles T1 verschlossen sind. Wird nun das zweite Teil T2 um die Achse 24 wie oben erwähnt verschwenkt, so bewegen sich die zweiten Eintrittsöffnungen 9 nach unten in die in Figur 6 dargestellte Position. In dieser sind die zweiten Eintrittsöffnungen 9 mit den Austrittsöffnungen 7 des Bereiches B1 verbunden und die ersten Eintrittsöffnungen 8 sind durch diesen Bereich B1 verschlossen.In the wings 19 are like the Figures 5 and 6 can be seen, above the inlet openings 8, two further inlet openings 9 are formed, which at the in the Figures 3 and 5 shown pivot position of the shower head 1 are closed by the area B1 of the part T1. If now the second part T2 is pivoted about the axis 24 as mentioned above, so move the second inlet openings 9 down in the in FIG. 6 shown position. In this, the second inlet openings 9 are connected to the outlet openings 7 of the area B1 and the first inlet openings 8 are closed by this area B1.

Die zweiten Eintrittsöffnungen 9 in den Kulissen 19 sind mit einem Raum 31 verbunden, welcher durch den Deckel 18, dessen Schürze 36 und das Oberteil 15 begrenzt wird. Dieser Raum führt über die o. g. Auslaßöffnung A1 in den nach oben offenen Aufnahmeraum 26 der Auslaufschale 21. Strömt nunmehr durch den Wasserführungskanal 2 Wasser zu, so gelangt dieses wieder in den Raum 6, der vom Bereich B1 des ersten Teiles T1 umgeben wird. Wiederum strömt das Wasser seitlich durch die Austrittsöffnungen 7, jedoch nun durch die zweiten Eintrittsöffnungen 9 nach außen in den Raum 31. Von dort gelangt das Wasser durch die Auslaßöffnung A1 in den Aufnahmeraum 26 der Auslaufschale 21. Da nunmehr die Überlaufkante 22 nach unten und die diametral gegenüberliegende Kante 29 nach oben versetzt sind, strömt das Wasser aus dem Aufnahmeraum 26 über die Überlaufkante 22 in einem geschlossenen Vorhang nach unten.The second inlet openings 9 in the scenes 19 are connected to a space 31 which is bounded by the lid 18, the skirt 36 and the upper part 15. This room leads over the o. G. Outlet opening A1 in the upwardly open receiving space 26 of the outlet shell 21. Now flows through the water supply channel 2 water, so this passes back into the space 6, which is surrounded by the area B1 of the first part T1. Again, the water flows laterally through the outlet openings 7, but now through the second inlet openings 9 outwardly into the space 31. From there, the water passes through the outlet opening A1 into the receiving space 26 of the outlet shell 21. Since now the overflow edge 22 down and the diametrically opposite edge 29 are offset upwards, the water flows from the receiving space 26 via the overflow edge 22 in a closed curtain down.

Wird das zweite Teil T2 in Gegenuhrzeigersinn wieder in die in Figur 1 gezeigte Stellung verschwenkt, so werden die zweiten Eintrittsöffnungen 9 in den Kulissen 19 wieder durch den Bereich B1 des ersten Teiles T1 verschlossen und die Austrittsöffnungen 7 des Bereichs B1 werden mit den unteren Eintrittsöffnungen 8 der Kulissen 19 verbunden. Das Wasser strömt dann wieder durch die Mehrzahl der unteren Auslaßöffnungen A2 und nicht mehr über die Auslaufschale 21 aus.If the second part T2 in the counterclockwise direction in the in FIG. 1 shown pivoted position, the second inlet openings 9 are closed in the scenes 19 again through the area B1 of the first part T1 and the outlet openings 7 of the area B1 are connected to the lower inlet openings 8 of the scenes 19. The water then flows through the majority of the lower outlet openings A2 and no longer via the outlet shell 21.

Bei dem oben beschriebenen Ausführungsbeispiel eines Brausekopfes 1 gibt es nur einen einzigen, zusammenhängenden Innenraum 14 zwischen dem Oberteil 15 und dem Unterteil 16 der Auslaufschale 21. Dieser Innenraum 14 kann jedoch auch durch Zwischenwände unterteilt sein, so daß durch eine geeignete Umstellung der Wasserführung Gruppen von Auslaßdüsen A2 mit Wasser beaufschlagt werden können, um verschiedene Strahlbilder zu erzeugen.In the embodiment of a shower head 1 described above, there is only a single, contiguous interior 14 between the upper part 15 and the lower part 16 of the outlet shell 21. However, this interior 14 may also be divided by intermediate walls, so that by a suitable conversion of the water supply groups of Outlet nozzles A2 can be supplied with water to produce different jet patterns.
