Abstract

The flexible cover (1b) for the shower head has a number of shaped stubs, with central holes, to clip into the hole pattern of the shower head (1a). The flexible cover is removable without having to dismantle the shower head and allows the outlet holes to be cleaned with ease ie. to remove lime scale simply by flexing the removed cover. The hollow stubs have outer collars (32) which grip behind the profile of the shower head to provide a simple ratchet grip which is not displaced by the pressure of the water. The stubs are shaped for a snug fit into the holes in the shower head. An alternate design has larger holes in the shower head to take double wall profiled stubs for an elastic fitting.

Description

Die Erfindung betrifft einen Brausekopf, insbesondere für eine Handbrause, mit

  • a) einem im wesentlichen glockenförmigen Gehäuse, in dem mindestens ein mit einem Wasserzulaufkanal verbindbarer Wasserraum ausgebildet ist;
  • b) einem Brauseboden, welcher das glockenförmige Gehäuse nach unten abschließt und umfaßt:
    • ba) eine Lochplatte aus starrem Material, die eine Vielzahl von Durchgangsbohrungen aufweist;
    • bb) einen lösbar mit der Lochplatte verbundenen Düseneinsatz aus elastischem Material, der eine an einer Fläche des Lochbodens anliegende Grundplatte und eine Vielzahl einstückig an die Grundplatte angeformter schlauchartiger Düsenansätze umfaßt, die jeweils von einem in einer Wasseraustrittsöffnung endenden Düsenkanal durchzogen sind und jeweils durch eine Durchgangsbohrung der Lochplatte hindurch geführt sind.
The invention relates to a shower head, in particular for a hand shower
  • a) an essentially bell-shaped housing in which at least one water space which can be connected to a water inlet channel is formed;
  • b) a shower base which closes off the bell-shaped housing and comprises:
    • ba) a perforated plate made of rigid material, which has a plurality of through holes;
    • bb) a nozzle insert made of elastic material which is detachably connected to the perforated plate and which comprises a base plate bearing against a surface of the perforated base and a plurality of hose-like nozzle attachments integrally formed on the base plate, each of which is penetrated by a nozzle channel ending in a water outlet opening and each through a through-hole the perforated plate are passed through.

Es ist bekannt, daß die Wasseraustrittsöffnungen an Brauseböden dazu neigen, im Laufe der Nutzungsdauer des Brausekopfes zu verkalken. Dies äußert sich zunächst in einem Strahlbild, dessen Geometrie vom Neuzustand abweicht, sowie einer geringeren abgegebenen Literleistung. Die Kalkablagerungen können so weit fortschreiten, daß schließlich die Wasseraustrittsöffnungen vollständig verstopft sind.It is known that the water outlet openings on shower bases tend to calcify over the course of the service life of the shower head. This is initially expressed in a spray pattern, the geometry of which deviates from the new condition, and a lower output per liter. The limescale deposits can progress so far that the water outlet openings eventually become completely blocked are.

Aus diesem Grunde ist es z.B. aus dem DE-GM 90 17 978 bekannt, die Wasseraustrittsöffnungen an schlauchartigen Düsenansätzen auszubilden, die über die Außenfläche des Brausebodens um eine bestimmte Strecke überstehen. Die schlauchartigen Düsenansätze sind aus einem elastomeren Material gefertigt und können durch manuelles Überstreichen so mechanisch gewalkt werden, daß die an den Mantelflächen der Düsenkanäle, insbesondere im Bereich der Wasseraustrittsöffnungen, abgelagerten Kalkschichten abgesprengt werden. Der Wasserdurchfluß durch die Wasseraustrittsöffnungen im Brauseboden ist dann wieder frei.For this reason it is e.g. from DE-GM 90 17 978 known to form the water outlet openings on hose-like nozzle approaches that protrude a certain distance over the outer surface of the shower base. The hose-like nozzle attachments are made of an elastomeric material and can be mechanically tumbled by manual painting so that the layers of lime deposited on the lateral surfaces of the nozzle channels, in particular in the area of the water outlet openings, are blasted off. The water flow through the water outlet openings in the shower base is then free again.

Ein Brausekopf der eingangs genannten Art ist vom Markt her bekannt. Sein Brauseboden ist aus einer starren, eine Vielzahl von Durchgangsbohrungen aufweisenden Lochplatte und einem elastisch-flexiblen, eine Vielzahl von Düsenansätzen aufweisenden Düseneinsatz zusammengesetzt. Alle Düsenansätze sind an eine Grundplatte des Düseneinsatzes angeformt. Diese liegt in montiertem Zustand an der Innenseite der Lochplatte an, sodaß der Wasserdruck den Düseneinsatz gegen die Lochplatte preßt. Die Düsenansätze sind von innen nach außen durch die Durchgangsbohrungen der Lochplatte hindurch geführt, derart, daß die freien Enden der Düsenansätze die Wasseraustrittsöffnungen bilden. Sind die Düsenkanäle, welche durch die Düsenansätze hindurchgeführt sind und an ihrem äußeren Ende die Wasseraustrittsöffnungen begrenzen, durch Kalkablagerungen verstopft oder verschmutzt, wird der Lochboden des bekannten Brausekopfes von dem Gehäuse abgenommen. Der Düseneinsatz kann nun von der Innenseite der Lochplatte abgezogen und von Hand gewalkt oder in sonstiger Weise gereinigt werden. Nach der Reinigung wird der Düseneinsatz wieder an seiner Stelle an der Innenfläche der Lochplatte befestigt; der so vormontierte Brauseboden wird dann erneut am Gehäuse des Brausekopfes montiert. Dieser bei der Reinigung des Düseneinsatzes jedesmal durchzuführende Vorgang ist jedoch verhältnismäßig kompliziert.A shower head of the type mentioned is known from the market. Its shower base is composed of a rigid perforated plate having a multiplicity of through-bores and an elastically flexible nozzle insert having a multiplicity of nozzle attachments. All nozzle attachments are molded onto a base plate of the nozzle insert. This is in the assembled state on the inside of the perforated plate, so that the water pressure presses the nozzle insert against the perforated plate. The nozzle attachments are passed through the through holes of the perforated plate from the inside out, such that the free ends of the nozzle attachments form the water outlet openings. If the nozzle channels, which are passed through the nozzle attachments and limit the water outlet openings at their outer end, are blocked or soiled by limescale deposits, the perforated base of the known shower head is removed from the housing. The nozzle insert can now be removed from the inside of the perforated plate and tumbled by hand or cleaned in any other way. After cleaning, the nozzle insert is reattached in its place on the inner surface of the perforated plate; of the pre-assembled shower base is then reassembled on the shower head housing. However, this process, which must be carried out each time when cleaning the nozzle insert, is relatively complicated.

Aufgabe der vorliegenden Erfindung ist es, einen Brausekopf der eingangs genannten Art so auszugestalten, daß der Düseneinsatz problemlos abzunehmen und zu reinigen ist.The object of the present invention is to design a shower head of the type mentioned at the outset in such a way that the nozzle insert can be removed and cleaned without problems.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß

  • c) die Grundplatte des Düseneinsatzes an der Außenfläche der Lochplatte anliegt, und
  • d) die Düsenansätze von außen her durch die Durchgangsbohrungen der Lochplatte durchgeschoben sind, derart, daß sich ihre freien Enden im Inneren des Brausekopfes befinden.
This object is achieved in that
  • c) the base plate of the nozzle insert rests on the outer surface of the perforated plate, and
  • d) the nozzle lugs are pushed from the outside through the through holes of the perforated plate, such that their free ends are inside the shower head.

Erfindungsgemäß wird also der Düseneinsatz von außen her an die starre Lochplatte angelegt; die Düseneinsätze werden von außen nach innen durch die Durchgangsbohrungen der Lochplatte hindurchgeführt, so daß nunmehr nicht an den freien Enden der Düsenansätze, die im Inneren des Brausekopfes zu liegen kommen, sondern an dem mit der Grundplatte des Düseneinsatzes verwachsenen Ende die Wasseraustrittsöffnungen gebildet sind. Besondere Rastmittel sorgen dafür, daß sich der Düseneinsatz auch unter dem im Innenraum des Brausekopfes herrschenden Wasserdruck nicht von der starren Lochplatte löst. Ein zusätzlicher Vorteil der erfindungsgemäßen Ausgestaltung ist, daß die Außenfläche des Brausebodens von der aus flexiblem Material hergestellten Grundplatte gebildet wird, diese Grundplatte also den gesamten Brauseboden vor Beschädigungen durch Stöße schützt.According to the invention, the nozzle insert is thus placed on the rigid perforated plate from the outside; the nozzle inserts are passed through the through holes of the perforated plate from the outside in, so that now the water outlet openings are not formed at the free ends of the nozzle attachments which come to lie inside the shower head, but at the end which has grown together with the base plate of the nozzle insert. Special locking means ensure that the nozzle insert does not detach from the rigid perforated plate even under the water pressure prevailing in the interior of the shower head. An additional advantage of the configuration according to the invention is that the outer surface of the shower base is formed by the base plate made of flexible material, ie this base plate protects the entire shower base from damage Protects bumps.

Am einfachsten ist diejenige Ausgestaltung der Erfindung, bei welcher

  • a) der Außendurchmesser der Düsenansätze des Düseneinsatzes mit dem Durchmesser der Durchgangsbohrungen der Lochplatte übereinstimmt, und
  • b) an die äußeren Mantelflächen der Düsenansätze jeweils ein radial überstehender Haltebund angeformt ist, der in montiertem Zustand an der Innenfläche der Lochplatte anliegt.
The simplest is the embodiment of the invention in which
  • a) the outer diameter of the nozzle attachments of the nozzle insert corresponds to the diameter of the through holes of the perforated plate, and
  • b) a radially projecting retaining collar is molded onto the outer lateral surfaces of the nozzle attachments, which, when assembled, rests against the inner surface of the perforated plate.

Noch günstiger im Blick auf die Reinigungsmöglichkeiten, wenn auch ein wenig teurer ist diejenige Ausgestaltung der Erfindung, bei welcher

  • a) der Außendurchmesser der Düsenansätze des Düseneinsatzes kleiner als der Durchmesser der Durchgangsbohrungen der Lochplatte ist;
  • b) an die Grundplatte des Düseneinsatzes Haltekrägen angeformt sind, die jeweils einen Düsenansatz umgeben und deren Außendurchmesser dem Durchmesser der Durchgangsbohrungen der Lochplatte entspricht;
  • c) an die äußeren Mantelfläche der Haltekrägen jeweils ein radial überstehender Haltebund angeformt ist, der in montiertem Zustand an der Innenfläche der Lochplatte anliegt.
The embodiment of the invention in which cleaning is even more economical with regard to the cleaning options, albeit a little more expensive
  • a) the outer diameter of the nozzle attachments of the nozzle insert is smaller than the diameter of the through holes of the perforated plate;
  • b) retaining collars are formed on the base plate of the nozzle insert, each of which surrounds a nozzle attachment and the outer diameter of which corresponds to the diameter of the through holes in the perforated plate;
  • c) a radially projecting retaining collar is molded onto the outer circumferential surface of the retaining collars, which in the assembled state rests against the inner surface of the perforated plate.

Bei diesem Ausführungsbeispiel entsteht zwischen den Düsenansätzen und den Haltekrägen ein Ringraum, welcher in gewissem Umfange ein Walken der Düsenansätze von Hand auch ohne Abnehmen des Düseneinsatzes von der Lochplatte gestattet.In this exemplary embodiment, an annular space is created between the nozzle attachments and the retaining collars, which to a certain extent allows the nozzle attachments to be flexed manually permitted without removing the nozzle insert from the perforated plate.

Das Abnehmen des Düseneinsatzes von der Lochplatte wird dann erleichtert, wenn der Haltebund an einer Anfasung des inneren Endes der entsprechenden Durchgangsbohrung anliegt.Removal of the nozzle insert from the perforated plate is then facilitated if the retaining collar rests on a chamfer on the inner end of the corresponding through hole.

Brauseköpfe der hier interessierenden Art werden häufig als sogenannte "Mehrfunktionsbrausen" ausgeführt. Dies bedeutet, daß das im allgemeinen über den Handgriff zuströmende Wasser mittels eines Umstellventiles auf einen von zwei im Gehäuse ausgebildeten Wasserräume geleitet wird. Die beiden Wasserräume kommunizieren jeweils mit einem Satz von Austrittsöffnungen im Brauseboden, wobei durch geeignete Geometrie der Wasseraustrittsöffnungen und/oder eine sonstige Behandlung des Wassers, z. B. eine Luftanreicherung, für einen unterschiedlichen Charakter der austretenden Wasserstrahlen in den beiden Betriebsarten gesorgt wird. Am häufigsten ist diejenige Ausgestaltung der Mehrfunktionsbrause, bei welcher in einer Betriebsart sogenannte "Hartstrahlen" mit verhältnismäßig hoher Geschwindigkeit und engem Querschnitt und in der zweiten Betriebsart sogenannte "Weichstrahlen", die mit Luft angereichert sind und einen verhältnismäßig großen Querschnitt aufweisen, austreten. Wendet man den erfinderischen Gedanken auf eine derartige Mehrfunktionsbrause an, so ist diejenige Ausgestaltung der Erfindung besonders vorteilhaft, bei welcher die freien Ringräume mit einem der Wasserräume kommunizieren und außerdem über ringsegmentförmige Öffnungen mit der Außenfläche des Brausebodens verbunden sind. Die Austrittsöffnungen der einen Art von Strahlen, z.B. der Weichstrahlen, liegen dabei also im wesentlichen an derselben Stelle wie die Austrittsöffnungen anderen Art von Strahlen, z.B. der der Hartstrahlen; das "grobe" Strahlbild des Brausekopfes ist also in beiden Betriebsarten dasselbe.Shower heads of the type of interest here are often designed as so-called "multi-function showers". This means that the water generally flowing in via the handle is directed to one of two water spaces formed in the housing by means of a diverter valve. The two water spaces each communicate with a set of outlet openings in the shower base, with suitable geometry of the water outlet openings and / or other treatment of the water, e.g. B. an air enrichment, for a different character of the emerging water jets in the two operating modes is ensured. The most common is the design of the multi-function shower head, in which so-called "hard jets" emerge at a relatively high speed and a narrow cross-section in one operating mode and so-called "soft jets" in the second operating mode, which are enriched with air and have a relatively large cross-section. If the inventive idea is applied to such a multi-function shower head, that embodiment of the invention is particularly advantageous in which the free annular spaces communicate with one of the water spaces and are also connected to the outer surface of the shower base via openings in the form of ring segments. The outlet openings of one type of beam, for example soft beams, are thus essentially at the same location as the outlet openings of another type of Rays, eg that of hard rays; the "rough" spray pattern of the shower head is therefore the same in both operating modes.

Der Brauseboden 1 umfaßt eine Lochplatte 1a aus verhältnismäßig starrem Material, der in konzentrischen Kreisen um seine in der Zeichnung nicht mehr dargestellte, von dieser weiter rechts zu denkende Mittelachse mehrere Sätze von Durchgangsbohrungen 3 aufweist.The shower base 1 comprises a perforated plate 1 a made of relatively rigid material, which has several sets of through bores 3 in concentric circles around its central axis, which is no longer shown in the drawing and can be thought of further to the right.

Der Brauseboden 1 umfaßt außerdem einen Düseneinsatz, der insgesamt das Bezugszeichen 1b trägt. Der Düseneinsatz 1b besteht aus einem elastomeren, verformbaren Kunststoff und ist in noch zu beschreibender Weise lösbar an der Lochplatte 1a befestigt. Wie Figur 1 zu entnehmen ist, umfaßt der Düseneinsatz 1b eine im wesentliche ebene Grundplatte 9, die sich an der Außen- und damit Unterseite der Lochplatte 1a entlang bis zu deren äußerem Rand erstreckt. Im Bereich des Außenrandes ist die Grundplatte 9 des Düseneinsatzes 1b mit einem ringförmigen Dichtwulst 30 versehen, der in eine komplementär geformte Nut 31 an der Unterseite der Lochplatte 1a eingreift.The shower base 1 also comprises a nozzle insert, which bears the overall reference number 1b. The nozzle insert 1b consists of an elastomeric, deformable plastic and is detachably attached to the perforated plate 1a in a manner to be described. As can be seen in FIG. 1, The nozzle insert 1b comprises a substantially flat base plate 9 which extends along the outer and thus underside of the perforated plate 1a up to the outer edge thereof. In the area of the outer edge, the base plate 9 of the nozzle insert 1b is provided with an annular sealing bead 30 which engages in a complementarily shaped groove 31 on the underside of the perforated plate 1a.

An die Grundplatte 9 des Düseneinsatzes 1b sind, konzentrisch zu den Sätzen von Durchgangsbohrungen 3 in der Lochplatte 1a, schlauchartige Düsenansätze 10 angespritzt, die sich durch die entsprechenden Bohrungen 3 der Lochplatte 1 hindurch ins Innere des Brausekopfes erstrecken. Der Außendurchmesser der Düsenansätze 10 entspricht dabei dem Durchmesser der Durchgangsbohrungen 3 in der Lochplatte 1a.On the base plate 9 of the nozzle insert 1b, hose-like nozzle extensions 10 are injection-molded, concentrically to the sets of through holes 3 in the perforated plate 1a, which extend through the corresponding holes 3 of the perforated plate 1 into the interior of the shower head. The outer diameter of the nozzle lugs 10 corresponds to the diameter of the through holes 3 in the perforated plate 1a.

Die Mantelflächen der Düsenansätze 10 sind jeweils mit einem ringförmigen Haltebund 32 ausgeformt, dessen axiale Höhe so gewählt ist, daß der Haltebund 32 in montiertem Zustand auf der Innenfläche der Lochplatte 1a bzw. einer im Bereich des dortigen Endes der Durchgangsbohrungen 3 angebrachten Anfasung 33 zu liegen kommt.The lateral surfaces of the nozzle lugs 10 are each formed with an annular retaining collar 32, the axial height of which is selected so that the retaining collar 32 lies in the assembled state on the inner surface of the perforated plate 1a or a chamfer 33 provided in the region of the end of the through bores 3 there is coming.

Die Düsenansätze 10 werden jeweils axial von Düsenkanälen 13 durchsetzt, die sich in ihrem äußeren Bereich konisch verjüngen, derart, daß die hier durchströmenden, aus Austrittsöffnungen 15 austretenden Wasserstrahlen eine Fokussierung und Beschleunigung erfahren.The nozzle attachments 10 are each axially penetrated by nozzle channels 13, which taper conically in their outer area, in such a way that the water jets flowing through them and emerging from outlet openings 15 experience focusing and acceleration.

Die Funktion des oben beschriebenen Brausekopfes ist wie folgt:
Im Betrieb des Brausekopfes werden die die Düsenansätze 10 durchsetzenden Düsenkanäle von oben her mit Wasser in geeigneter, hier nicht interessierender Weise gespeist. Im Laufe der Zeit lagern sich innerhalb der Düsenkanäle 13, insbesondere aber im Bereich der Austrittsöffnungen 15 mit verhältnismäßig kleinem Querschnitt, Kalkschichten ab, die den offenen Durchflußquerschnitt verkleinern und schließlich zu einem vollständigen Verstopfen der Düsenkanäle 13 führen können. Ist ein solcher Zustand eingetreten, kann der gesamte Düseneinsatz 1b durch axialen Zug von der Lochplatte 1a abgenommen werden; bei diesem Vorgang sind die Anfasungen 33 im oberen Endbereich der Durchgangsbohrungen 3 der Lochplatte 1a hilfreich. Ist der Düseneinsatz 1b von dem Brausekopf gelöst, so kann er von Hand derart gewalkt werden, daß die an den Wandungen der Düsenkanäle 13 abgelagerten Schichten abgesprengt werden. Zusätzlich ist selbstverständlich auch eine Reinigung des Düseneinsatzes 1b mit einem geeigneten Reinigungsgerät, z.B. einem Schwamm, oder mit Reinigungsmitteln möglich.The function of the shower head described above is as follows:
In the operation of the shower head, the nozzle channels passing through the nozzle attachments 10 are filled with water from above suitable, not relevant here. Over time, layers of limescale build up inside the nozzle channels 13, but in particular in the area of the outlet openings 15 with a relatively small cross section, which reduce the open flow cross section and can ultimately lead to a complete blockage of the nozzle channels 13. If such a condition has occurred, the entire nozzle insert 1b can be removed from the perforated plate 1a by axial pull; the chamfers 33 in the upper end region of the through bores 3 of the perforated plate 1a are helpful in this process. If the nozzle insert 1b is detached from the shower head, it can be tumbled by hand in such a way that the layers deposited on the walls of the nozzle channels 13 are blasted off. In addition, it is of course also possible to clean the nozzle insert 1b with a suitable cleaning device, for example a sponge, or with cleaning agents.

Nach Abschluß der Reinigung werden die Düsenansätze 10 des Düseneinsatzes 1b wieder in die entsprechenden Durchgangsbohrungen 3 der Lochplatte 1a eingeführt. Die Haltebünde 32 an den Außenmantelflächen der Düsenansätze 10 werden komprimiert durch die Durchgangsbohrungen 3 hindurchgeführt, bis sie dann im Bereich der Anfasungen 33 wieder auffedern können. Der Düseneinsatz 1b ist nunmehr wieder an die Lochplatte 1a "angeknüpft".After cleaning is complete, the nozzle attachments 10 of the nozzle insert 1b are reinserted into the corresponding through bores 3 of the perforated plate 1a. The retaining collars 32 on the outer lateral surfaces of the nozzle attachments 10 are compressed through the through holes 3 until they can then spring open again in the region of the chamfers 33. The nozzle insert 1b is now "attached" to the perforated plate 1a.

Das Reinigen des Düseneinsatzes 1b von Kalkablagerungen ist also beim beschriebenen Brauseboden möglich, ohne die Lochplatte 1a vom Brausekopf zu entfernen. Zudem schützt die Grundplatte 9 des Düseneinsatzes 1b, die sich an der gesamten Außenfläche der Lochplatte 1a entlang erstreckt, den Brauseboden insbesondere auch im abgerundeten Außenbereich vor Beschädigung durch Stöße.Limescale deposits can be cleaned from the nozzle insert 1b in the shower base described without removing the perforated plate 1a from the shower head. In addition, the base plate 9 of the nozzle insert 1b, which extends along the entire outer surface of the perforated plate 1a, protects the shower base, especially in the rounded outer area, from damage caused by impacts.

In Figur 2 ist ein zweites Ausführungsbeispiel eines Brausebodens im Radialschnitt dargestellt, welches dem oben anhand von Figur 1 erläuterten sehr ähnlich ist. Entsprechende Teile sind daher mit demselben Bezugszeichen, zuzüglich 100, gekennzeichnet.FIG. 2 shows a second exemplary embodiment of a shower base in radial section, which is very similar to that explained above with reference to FIG. 1. Corresponding parts are therefore identified by the same reference number plus 100.

In Figur 2 ist wiederum eine Lochplatte 101a erkennbar, die zusammen mit einem Düseneinsatz 101b den Brauseboden 101 eines Brausekopfes bilden. Die Lochplatte 101a enthält auf konzentrischen Kreisen um ihre Mittelachse eine Vielzahl von Durchgangsbohrungen 103.A perforated plate 101a can again be seen in FIG. 2, which together with a nozzle insert 101b form the shower base 101 of a shower head. The perforated plate 101a contains a plurality of through bores 103 on concentric circles around its central axis.

Der Düseneinsatz 101b umfaßt einstückig eine Grundplatte 109 sowie an die Grundplatte 109 angeformte Düsenansätze 110, welche jeweils von Düsenkanälen 113 axial durchsetzt werden. Wie der Figur 2 zu entnehmen ist, ist jedoch der Außendurchmesser der Düsenansätze 110 deutlich kleiner als der Durchmesser der zugeordneten Durchgangsbohrungen 103 der Lochplatte 101a.The nozzle insert 101b comprises in one piece a base plate 109 and nozzle extensions 110 molded onto the base plate 109, each of which is axially penetrated by nozzle channels 113. As can be seen in FIG. 2, however, the outer diameter of the nozzle attachments 110 is significantly smaller than the diameter of the assigned through bores 103 of the perforated plate 101a.

An die Grundplatte 109 des Düseneinsatzes 101b sind nunmehr konzentrisch um jeden Düsenansatz 110 herum zusätzliche Haltekrägen 120 angeformt, deren Außendurchmesser dem Durchmesser der Durchgangsbohrungen 103 in der Lochplatte 101a entspricht. An ihrem nach oben, also ins Innere des Brausekopfes zeigenden Rand weisen die Haltekrägen 120 einen Haltebund 132 auf. Dieser ragt auf der Innenseite der Lochplatte 101a nach außen über und sichert zusammen mit den entsprechenden Haltebünden 132 an allen anderen Düsenansätzen 110 den Düseneinsatz 101b an der Lochplatte 101a.Additional retaining collars 120, the outer diameter of which corresponds to the diameter of the through bores 103 in the perforated plate 101a, are now integrally formed on the base plate 109 of the nozzle insert 101b. The retaining collars 120 have a retaining collar 132 on their edge pointing upwards, that is to say into the interior of the shower head. This protrudes outward on the inside of the perforated plate 101a and, together with the corresponding retaining collars 132, secures the nozzle insert 101b on the perforated plate 101a on all other nozzle attachments 110.

Der Düseneinsatz 101b kann also dadurch an der Lochplatte 101a montiert werden, daß die Haltekrägen 120 durch die entsprechenden Durchgangsbohrungen 103 der Lochplatte 101a hindurch geschoben werden, was aufgrund der Elastizität des Materials des Düseneinsatzes 101b möglich ist. Sobald die Haltebünde 132 die Durchgangsbohrungen 103 durchtreten haben, federn sie auf und bilden so eine Fixierung für den Düseneinsatz 101b. Das Einführen der Haltekrägen 120 und insbesondere der an diese angeformten Haltebunde 132 in die Durchgangsbohrungen 103 der Lochplatte 101a wird durch eine Abschrägung 122 am äußeren Ende der Durchgangsbohrungen 103 erleichtert.The nozzle insert 101b can thus be mounted on the perforated plate 101a in that the retaining collars 120 through the corresponding through bores 103 of the perforated plate 101a are pushed through, which is possible due to the elasticity of the material of the nozzle insert 101b. As soon as the holding collars 132 have passed through the through bores 103, they spring open and thus form a fixation for the nozzle insert 101b. The insertion of the retaining collars 120 and in particular the retaining collars 132 molded onto them into the through bores 103 of the perforated plate 101a is facilitated by a bevel 122 at the outer end of the through bores 103.

Der in Figur 2 dargestellte Brausekopf unterscheidet sich von demjenigen, der in Figur 1 gezeigt ist, im wesentlichen dadurch, daß zwischen den Düsenansätzen 110 und den Haltekrägen 120 jeweils ein Ringraum 140 ausgebildet ist. Aufgrund dieses Ringraumes 140 ist es möglich, schon ohne Abnehmen des Düseneinsatzes 101b von der Lochplatte 101a ein gewisses Walken im Bereich der Wasseraustrittsöffnungen 115 zu bewirken, indem der Benutzer mit der Hand bzw. dem Finger unter Druck an der unteren (Außen-)Fläche des Düseneinsatzes 101b entlang streicht und dabei den Düseneinsatz 101b im Bereich der Wasseraustrittsöffnungen 115 verformt. Die so erzielbare Walkung des Düseneinsatzes 101b kann in vielen Fällen schon ausreichen, abgelagerte Kalkschichten von der Wand der Düsenkanäle 113 abzusprengen. Das Abnehmen des Düseneinsatzes 101b von der Lochplatte 101a, wie oben beschrieben, ist also beim Ausführungsbeispiel von Figur 2 nur noch ausnahmsweise bzw. in sehr großen Zeitabständen erforderlich.The shower head shown in FIG. 2 differs from that shown in FIG. 1 essentially in that an annular space 140 is formed between the nozzle attachments 110 and the retaining collars 120. Because of this annular space 140, it is possible to effect a certain flexing in the region of the water outlet openings 115 without removing the nozzle insert 101b from the perforated plate 101a, by the user pressing the hand (or finger) on the lower (outer) surface of the Brushes along the nozzle insert 101b and deforms the nozzle insert 101b in the region of the water outlet openings 115. The flexing of the nozzle insert 101b that can be achieved in this way can, in many cases, be sufficient to blow off deposited limescale layers from the wall of the nozzle channels 113. The removal of the nozzle insert 101b from the perforated plate 101a, as described above, is therefore only required in the exemplary embodiment of FIG. 2 only exceptionally or at very large time intervals.

Der in Figur 3 dargestellte Brausekopf ist eine Variante des Ausführungsbeispieles von Figur 2. Teile, die solchen von Figur 1 entsprechen, sind mit demselben Bezugszeichen zzgl. 200 gekennzeichnet.The shower head shown in FIG. 3 is a variant of the exemplary embodiment in FIG. 2. Parts which correspond to those in FIG. 1 are identified by the same reference number plus 200.

Der wesentliche Unterschied zwischen den Ausführungsbeispielen der Figuren 2 und 3 ist folgender:The main difference between the exemplary embodiments in FIGS. 2 and 3 is as follows:

Während beim Ausführungsbeispiel von Figur 2 die Ringräume 140, welche die Düsenansätze 110 konzentrisch umgeben, ausschließlich die Funktion hatten, die Walkbarkeit der Düsenansätze 110 zu erleichtern, kommt den Ringräumen 140 beim Ausführungsbeispiel von Figur 3 eine weitere Funktion zu:While in the exemplary embodiment in FIG. 2 the annular spaces 140, which surround the nozzle attachments 110 concentrically, only had the function of facilitating the walkability of the nozzle attachments 110, the annular spaces 140 in the exemplary embodiment in FIG. 3 have a further function:

Wie in Figur 3 zu erkennen ist, steht der Grund der Ringräume 240 über Öffnungen 250 mit der Außenfläche des Brausebodens, also der Außenfläche der Grundplatte 209, in Verbindung. Die Öffnungen 250 haben die Form von Ringsegmenten, welche die Austrittsöffnungen 215 konzentrisch umgeben.As can be seen in FIG. 3, the bottom of the annular spaces 240 is connected via openings 250 to the outer surface of the shower base, that is to say the outer surface of the base plate 209. The openings 250 have the form of ring segments which concentrically surround the outlet openings 215.

Der Brauseboden 201 von Figur 3 wird folgendermaßen innerhalb des Brausekopfes montiert:The shower base 201 from FIG. 3 is installed inside the shower head as follows:

Die in Figur 3 nach oben zeigenden, freien Enden der Düsenansätze 210 werden in einer Trennwand des Brausekopfes so befestigt, daß die Düsenkanäle 213 mit einem Wasserraum kommunizieren, der auf der von dem Brauseboden 201 abgewandten Seite der Trennwand liegt.The free ends of the nozzle attachments 210 pointing upward in FIG. 3 are fastened in a partition of the shower head in such a way that the nozzle channels 213 communicate with a water space which is located on the side of the partition facing away from the shower base 201.

Die Ringräume 240 dagegen sind mit einem zweiten Wasserraum verbunden, welcher auf der dem Brauseboden 201 zugewandten Seite der Trennwand angeordnet ist.The annular spaces 240, however, are connected to a second water space, which is arranged on the side of the partition facing the shower base 201.

Die Funktion des Ausführungsbeispieles von Figur 3 ist wie folgt:
In der einen Betriebsart der Brause wird das zuströmende Wasser demjenigen Wasserraum zugeleitet, der auf der dem Brauseboden 201 abgwandten Seite der Trennwand liegt. Das Wasser strömt dann durch die Düsenkanäle 213 der Düsenansätze 210 hindurch und tritt aus den Wasseraustrittsöffnungen 215 als "Hartstrahlen" aus.The function of the embodiment of Figure 3 is as follows:
In one operating mode of the shower, the inflowing water is fed to the water space on the is the side of the partition facing away from the shower base 201. The water then flows through the nozzle channels 213 of the nozzle attachments 210 and emerges from the water outlet openings 215 as "hard jets".

In der zweiten Betriebsart des Brausekopfes wird der dem Brauseboden 201 benachbarte Wasserraum mit der Wasserzufuhr verbunden. Das diesen Weg nehmende Wasser wird z.B. mit Luft angereichert, gelangt in die Ringräume 240 und tritt von dort über die Öffnungen 250 als "Weichstrahlen" aus. Die grobe Position der "Weichstrahlen" auf dem Brauseboden 201 bleibt dabei im wesentlichen dieselbe wie diejenige der "Hartstrahlen", so daß also das Strahlbild des Brausekopfes in beiden Betriebsarten im wesentlichen dasselbe ist.In the second operating mode of the shower head, the water space adjacent to the shower base 201 is connected to the water supply. The water taking this route is e.g. enriched with air, enters the annular spaces 240 and exits from there via the openings 250 as "soft rays". The rough position of the "soft jets" on the shower base 201 remains essentially the same as that of the "hard jets", so that the spray pattern of the shower head is essentially the same in both operating modes.
