Abstract

The inventive shower head comprises an outer housing (6) in which a switchable valve, which is provided with a valve body (5) and with a closing body (9) that can be displaced therein, is accommodated. One end of the closing body (9) is arranged underneath a membrane (2) that can be pressed inwards. This end of the closing body is arranged in such a way that, in order to change the type of stream, the closing body (9) can be displaced from a first valve seat (16) to a second valve seat (17) by pressing the membrane (2) inwards against the repelling force of a spring (7). Restoring means are provided with which the closing body (9) can be moved from a valve seat (17) to a second valve seat (16). The membrane (2) is arranged in a rotating cover (1) and the closing body (9) can be moved from a valve seat (16, 17) toward the other valve seat (16, 17) by turning the cover (1).

Description

Brausekopf shower head
Die Erfindung betrifft einen Brausekopf mit einem äusseren Gehäuse, in dem ein umstellbares Ventil mit einem Ventilkörper und einem verschieblich in diesem geführten Verschlusskörper untergebracht ist, wobei ein Ende des Verschlusskörpers unterhalb einer eindrückbaren Membran angeordnet ist, derart, dass der Verschlusskörper zum Umstellen der Strahlart durch Eindrücken der Membran gegen die rückwirkende Kraft einer Feder von einem ersten Ventilsitz auf einen zweiten Ventilsitz verschiebbar ist, mit Rückstellmitteln, mit denen der Verschlusskörper gegen einen Wasserdruck vom zweiten Ventilsitz gegen den ersten Ventilsitz bewegbar ist.The invention relates to a shower head with an outer housing, in which a convertible valve with a valve body and a sliding body guided displaceably therein is accommodated, one end of the closing body being arranged below a push-in membrane, such that the closing body is used to change the spray type Pressing in the membrane against the retroactive force of a spring is displaceable from a first valve seat to a second valve seat, with restoring means with which the closure body can be moved against the first valve seat against water pressure from the second valve seat.
Brausen dieser Art sind allgemein bekannt. Sie ermöglichen die Umstellung der Strahlart, beispielsweise von einem Perlator- strahl auf einen Siebstrahl. Dazu wird die Membran eingedrückt und damit der Verschlusskorper des Ventils auf einen unteren Ventilsitz bewegt. Bei hinreichendem Wasserdruck wird der Verschlusskorper in dieser Stellung gehalten und das Wasser gelangt durch Austrittsόffnungen, die den Siebstrahl ergeben. Bei einem Fliessdruck von weniger als beispielsweise 0,5 bar bleibt dieser Siebstrahl erhalten. Um wieder auf den Perlatorstrahl umzustel- len, muss der Verschlusskorper wieder angehoben werden. Bei der Brause nach der EP-A-0695490 erfolgt dieses Anheben mittels eines Hebels, der am oberen Ende des Ventilkorpers angelenkt und unterhalb der Membran angeordnet ist. Es gibt auch andere Einstellmittel, mit denen der Ventilkorper angehoben werden kann. Nachteilig bei der genannten Ausfuhrung mit dem Umstellhebel ist insbesondere die vergleichsweise ungunstige Handhabung, da zur Betätigung die dazu geeignete Position der Membran gefunden werden muss. Durch geeignete Markierung kann die Handhabung etwas verständlicher gestaltet werden, dies ist aber in vielen Fallen nicht zweckmassig.Showers of this type are generally known. They make it possible to change the jet type, for example from a aerator jet to a sieve jet. To do this, the membrane is pressed in and the valve body is moved to a lower valve seat. When the water pressure is sufficient, the breech block is held in this position and the water passes through the outlet openings that form the sieve jet. This sieve jet is retained at a flow pressure of less than 0.5 bar, for example. To switch back to the aerator jet len, the breech block must be raised again. In the shower according to EP-A-0695490, this lifting takes place by means of a lever which is articulated at the upper end of the valve body and is arranged below the membrane. There are also other adjustment means with which the valve body can be raised. A disadvantage of the above-mentioned embodiment with the changeover lever is, in particular, the comparatively unfavorable handling, since the suitable position of the membrane must be found for actuation. Appropriate marking can make handling easier to understand, but in many cases this is not practical.
Der Erfindung liegt die Aufgabe zugrunde eine Brause der genannten Art zu schaffen, welche einfacher betatigtbar ist und die trotzdem mit wenigen und robusten Teilen herstellbar ist. Die Brause soll zudem funktionssicher und kostengünstig herstellbar sein .The invention has for its object to provide a shower of the type mentioned, which is easier to operate and which can still be produced with few and robust parts. The shower should also be reliable and inexpensive to manufacture.
Die Aufgabe ist bei einer gattungsgemassen Brause gemass Anspruch 1 gelost.The problem is solved in a generic shower according to claim 1.
Beim erfindungsgemassen Brausekopf ist somit die Membran in einem drehbaren Deckel integriert. Die Membran ist kuppelformig und damit oberseitig des Brausekopfes vorstehend. Ein Ertasten der geeigneten Position auf der Membran ist somit nicht erforderlich.In the shower head according to the invention, the membrane is thus integrated in a rotatable cover. The membrane is dome-shaped and thus protrudes from the top of the shower head. It is therefore not necessary to feel the appropriate position on the membrane.
Für die Erfindung ist zudem wesentlich, dass die Membran und der Deckel ohne Zwischenraum als eine Einheit hergestellt werden können. Bekannte Brausen dieser Art weisen vielfach eine Rille unterhalb des Druckers auf. Beim erfindungsgemassen Brausekopf kann durch die Anordnung der Membran im Deckel ein solcher Zwischenraum vermieden werden. Dies ist insbesondere aus hygienischen Gründen vorteilhaft und ermöglicht ein einfaches Reinigen des Brausekopfs Die Ruckstellung erfolgt beim erfindungsgemassen Brausekopf durch Drehen des Deckels, und damit durch gleichzeitiges Drehen der Membran, die im Deckel integriert ist. Das Drehen des Dek- kels ist sehr einfach und ergonomisch. Beispielsweise kann am Deckel eine radial vorstehende Betatigungsnase angeformt sein.It is also essential for the invention that the membrane and the cover can be produced as a unit without a gap. Known showers of this type often have a groove below the printer. In the shower head according to the invention, such an intermediate space can be avoided by the arrangement of the membrane in the cover. This is particularly advantageous for hygienic reasons and enables easy cleaning of the shower head The reset takes place in the shower head according to the invention by turning the cover, and thus by simultaneously turning the membrane, which is integrated in the cover. Turning the lid is very easy and ergonomic. For example, a radially protruding actuating nose can be formed on the cover.
Die Umstellung des Ventils wird vorzugsweise über eine Steuerkurve erreicht, die am Ventilkorper angeordnet ist und die beim Drehen des Deckels den Verschlusskorper anhebt. Diese Ruckstellung erfolgt durch Drehen des Deckels im Uhrzeiger- oder Gegenuhrzeigersinn. Denkbar ist hier auch eine Weiterbildung, bei welcher beim Drehen des Deckels in einer Richtung die Einstellung des Ventils arretiert wird. Eine solche Arretierung hat den Vorteil, dass der Siebstrahl auch bei einer Verminderung des Fliessdruckes beispielsweise unter 0,5 bar erhalten bleibt.The changeover of the valve is preferably achieved via a control curve which is arranged on the valve body and which lifts the closure body when the cover is turned. This is reset by turning the cover clockwise or counterclockwise. A further development is also conceivable in which the setting of the valve is locked when the cover is turned in one direction. Such a locking has the advantage that the sieve jet is retained even when the flow pressure is reduced, for example below 0.5 bar.
Der Verschlusskorper wird vorzugsweise durch einen tastenformi- gen Drucker betätigt, der am oberen Ende des Verschlusskorpers angeordnet ist. Dieser Drucker weist vorzugsweise oberseitig eine gewölbte Flache auf, die sich etwa parallel zur Unterseite der Membran erstreckt. Die Erstreckung ist vorzugsweise so gross, dass der Drucker im wesentlichen an jeder Position der Membran nach unten bewegt werden kann.The closure body is preferably actuated by a button-shaped printer which is arranged at the upper end of the closure body. This printer preferably has a curved surface on the top, which extends approximately parallel to the underside of the membrane. The extent is preferably so large that the printer can be moved down substantially at any position of the membrane.
Der Deckel ist gemass einer Weiterbildung der Erfindung ringförmig und die Membran in Draufsicht im wesentlichen kreisförmig. Die Membran ist vorzugsweise in den Deckel eingerastet, oder im Zweipolymerverfahren direkt an den Deckel angeformt. Dadurch kann ein Teil eingespart und die Montage vereinfacht werden.According to a further development of the invention, the cover is ring-shaped and the membrane is essentially circular in plan view. The membrane is preferably snapped into the cover or molded directly onto the cover in a two-polymer process. This saves a part and simplifies assembly.
Weitere vorteilhafte Merkmale ergeben sich aus den abhangigen Patentansprüchen, der nachfolgenden Beschreibung sowie der Zeichnung . Ein Ausfuhrungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung naher erläutert. Es zeigen:Further advantageous features result from the dependent claims, the following description and the drawing. An exemplary embodiment of the invention is explained in more detail below with reference to the drawing. Show it:

Der Brausekopf weist ein Gehäuse 6 auf, das einen Kopfteil 6a besitzt, an welchem ein hier nur teilweise gezeigter Rohrteil 6b angeformt ist. Der Kopfteil 6a nimmt einen Ventilkorper 5 auf, der mit Rastnocken 5d im Gehäuse 6 verankert ist. Ein rohrformi- ger Einsatz 11 ist am hier nicht gezeigten Ende in bekannter Weise an einer Wasserleitung anschliessbar . Dieser Einsatz 11 fuhrt mit einem Durchgang 11a das Wasser zu einer Öffnung 12 des Ventilkorpers 5. Der Einsatz 11 liegt dicht am Ventilkorper 5 an und ist mittels eines von oben aufgeschobenen Riegels 8 losbar mit dem Ventilkorper 5 verbunden.The shower head has a housing 6, which has a head part 6a, on which a pipe part 6b, which is only partially shown here, is formed. The head part 6a receives a valve body 5, which is anchored in the housing 6 with locking cams 5d. A tubular insert 11 can be connected to a water pipe in a known manner at the end not shown here. This insert 11 guides the water through a passage 11a to an opening 12 of the valve body 5. The insert 11 lies close to the valve body 5 and is detachably connected to the valve body 5 by means of a bolt 8 pushed on from above.
Der Ventilkorper 5 weist gemass Figur 3 ein Innengewinde 15 auf, in das ein Sieb 4 eingeschraubt ist. Zwischen dem Sieb 4 und dem Ventilgehause 5 ist ein zylindrischer Einsatz 10 angeordnet, der an seinem Umfang mit dem Ventilkorper 5 verbunden ist und der einen Durchgang 14 aufweist. Das Sieb 4 ist zur Erzeugung eines Siebstrahles mit einer Mehrzahl von vergleichsweise schmalen Du- senoffnungen 18 versehen.According to FIG. 3, the valve body 5 has an internal thread 15 into which a sieve 4 is screwed. A cylindrical insert 10 is arranged between the sieve 4 and the valve housing 5, which is connected at its periphery to the valve body 5 and which has a passage 14. The screen 4 is provided with a plurality of comparatively narrow nozzle openings 18 to produce a screen jet.
Im Ventilkorper 5 ist ein Verschlusskorper 9 angeordnet, der ei¬ nen Ventilsitz 9a besitzt, welcher in Figur 1 an einem ersten und oberen Ventilsitz 16 anliegt. Am oberen Ende des Verschluss- orpers 9 ist ein becherförmiger Drucker 3 aufgerastet, der durch eine Druckfeder 7 in der in Figur 1 gezeigten Position gehalten wird Diese Druckfeder 7 ist gleichseitig eine lorsions- feder, wie weiter unten noch erläutert wird. Der Drucker 3 weist zwei radial vorstehende Mitnehmernocken 3a auf, die jeweils zwischen zwei Fuhrungsnocken lb gefuhrt sind, wie insbesondere die Figur 2 erkennen lasst. Diese Fuhrung ermöglicht eine vertikale Bewegung des Druckers 3 bzw. des Verschlusskorpers 9 im Deckel 1.In the valve body 5, a closure body 9 is disposed, the egg ¬ NEN valve seat 9a has, which rests in Figure 1 at a first and upper valve seat sixteenth A cup-shaped printer 3 is snapped onto the upper end of the closure body 9 and is held in the position shown in FIG. 1 by a compression spring 7. This compression spring 7 is on the same side a spring, as will be explained below. The printer 3 has two radially projecting driver cams 3a, each of which is guided between two guide cams 1b, as can be seen in particular in FIG. This guide enables a vertical movement of the printer 3 or the closure body 9 in the cover 1.
Ein Deckel 1 ist ringförmig ausgebildet und weist eine obere kreisrunde Öffnung Id auf, in die eine gummielastische Membran 2 eingesetzt ist. Vorzugsweise ist die Membran 2 mittels Rastnokken 2a auf den Deckel 1 aufgerastet. Die Membran 2 ist teilku- gelformig ausgebildet und oben sowie mittig grossflachig vorstehend. Die Membran 2 ist ferner bundig zur Außenseite des ring¬ förmigen Deckels 1. Der Deckel 1 ist am Ventilkorper 5 befestigt, verzugsweise mittels einer Bajonett- oder Rastverbindung.A lid 1 is ring-shaped and has an upper circular opening Id, into which a rubber-elastic membrane 2 is inserted. The membrane 2 is preferably snapped onto the cover 1 by means of latching cams 2a. The membrane 2 is formed in the shape of a part of a sphere and protrudes over a large area above and in the center. The diaphragm 2 is also secured flush to the outside of the ring-shaped ¬ lid 1. The lid 1 is on the valve body 5, warp by means of a bayonet or snap-in connection.
Unterhalb der Membran 2 ist der Drucker 3 angeordnet, der eine Oberseite 3d besitzt, die parallel zur Membran 2 verlauft und sich im wesentlichen über den gesamten Bereich der Öffnung ld erstreckt .The printer 3 is arranged below the membrane 2 and has an upper side 3d, which runs parallel to the membrane 2 and extends essentially over the entire area of the opening 1d.
In der in Figur 1 gezeigten Position ist der Verschlusskorper 9 in einer Position, in welcher das durch den Kanal 11a einströ¬ mende Wasser in den Kanal 14 und von diesem durch eine Öffnung 20 nach aussen gelangt. Ein weiterer Einsatz 21 ergibt den ge¬ nannten Perlatorstah] . Die Erzeugung eines solchen Strahles ist ansich dem Fachmann bekannt.In the embodiment shown in Figure 1 position of the closure body 9, in which the passes in a position through the channel 11a einströ ¬ Mende water in the channel 14 and from the outside through an opening 20. Another insert 21 gives the ge ¬ called Perlatorstah]. The generation of such a beam is known per se to the person skilled in the art.
Wird die Membran 2 gemass Figur 1 in Richtung des Pfeiles A ein¬ gedruckt, so wird der Drucker 3 durch die Membran beaufschlagt und gegen die ruckwirkende Kraft der Feder 7 wird der Ventiltel- ler 9a vom ersten Ventilsitz 16 abgehoben und gegen den zweiten Ventilsitz 17 bewegt. Das einströmende Wasser gelangt nun von der Öffnung 12 in den Kanal 13 und von diesem über eine weitere Öffnung 22 in einen Ringkanal 23 und von diesem durch die Düsen- Öffnungen 18 als Siebstahl nach aussen. Die Strahlart wird somit durch drucken der Membran 2 vom Perlatorstrahl auf den Siebstrahl umgestellt. Ist der Wasserdruck grosser als beispielsweise 0,5 bar, so halt das Wasser den Verschlusskorper 9 gegen die ruckwirkende Kraft der Feder 7 in dieser Stellung. Soll nun das Ventil umgestellt werden, so wird der Deckel 1 an einer vorstehenden Nase lc in Ansicht der Figur im Uhrzeigersinn um die Achse B gedreht. Hierbei kommen zwei Rippen 3b des Druckers 3 in Eingriff mit Steuerkurven 5a, die am Ventilkorper 5 angeformt sind. Durch diesen Eingriff wird der Drucker 3 nach oben bewegt, wobei er durch die Feder 7 unterstutzt wird. Anschlage 5e begrenzen diese Bewegung. Die vorqespannte Feder 7 spannt dem Drucker 3 gegen die Anschlagnocken 5f. Bei dieser Bewegung des Druckers 3 wird die Druckfeder 7 gespannt. Wird der Deckel 1 losgelassen, so bewegt die Feder 7 den Drucker 3 durch eine Schwenkbewegung um die Achse B wieder in die in Figur 2 gezeigte Position. Damit diese Feder 7 als Torsionsfeder wirken kann, sind ihre Enden entsprechend in einer Nut 5c des Ventilkorpers 5 und in einer hier nicht naher gezeigten Nut des Druckers 3 abgestutzt .If the membrane 2 ACCORDING Figure 1 in the direction of arrow A printed a ¬, the printer is acted upon by the membrane 3 and the Ventiltel- ler 9a is lifted off the first valve seat 16 and against the second valve seat 17 against the jerk force of the spring 7 emotional. The inflowing water now passes from the opening 12 into the channel 13 and from there via a further opening 22 into an annular channel 23 and from there through the nozzle Openings 18 to the outside as a screen. The jet type is thus changed from the aerator jet to the sieve jet by printing the membrane 2. If the water pressure is greater than 0.5 bar, for example, the water holds the closure body 9 in this position against the reactive force of the spring 7. If the valve is now to be changed over, the cover 1 is rotated clockwise around the axis B on a protruding nose 1c in the view of the figure. Here, two ribs 3b of the printer 3 come into engagement with control cams 5a, which are integrally formed on the valve body 5. As a result of this intervention, the printer 3 is moved upwards, being supported by the spring 7. Stops 5e limit this movement. The preloaded spring 7 tensions the printer 3 against the stop cams 5f. During this movement of the printer 3, the compression spring 7 is tensioned. If the cover 1 is released, the spring 7 moves the printer 3 back into the position shown in FIG. 2 by a pivoting movement about the axis B. So that this spring 7 can act as a torsion spring, its ends are correspondingly supported in a groove 5c of the valve body 5 and in a not shown groove of the printer 3.
Nach der Umstellung liegt der Ventilteller 9a wieder gemass Figur 1 am ersten Ventilsitz 16 an. Das Wasser gelangt durch die Öffnung 12 in den Kanal 14, wie oben erwähnt. Diese Stellung bleibt bej jedem Wasserdruck erhalten. Die Umstellung erfolgt wie erwähnt durch Drucken der Membran 2 in Richtung des Pfeils A. Da wie erwähnt die Membran 2 oben vorstehend und grossflachig ist, kann die Membran 2 auch mit der Handballe gedruckt werden, wobei gleichzeitig der Brausekopf von vorne gehalten wird Übli¬ cherweise wird zur Betätigung der Brausekopf mit einer Fland am Rohrteil 6b gehalten Der Druckpunkt auf der Membran 2 ist nicht kritisch und eine bestimmte Position muss nicht gefunden werden. Die Ruckstellung erfolgt wie erw hnt durch Drehen des Deckels 1. Das Drehen erfolgt vorzugsweise an der vorstehenden Nase lc. Der Brausekopf i t WIP ersichtlich weitgehend geschlossen und damit gegen Eindringen von Schmutz geschützt. Dies ist ein wesentlicher Gesichtspunkt, insbesondere dort wo besondere hygienische Anforderungen gestellt sind.After the changeover, the valve plate 9a rests against the first valve seat 16 in accordance with FIG. The water passes through the opening 12 into the channel 14, as mentioned above. This position remains with every water pressure. The conversion is carried out as mentioned by printing of the membrane 2 in the direction of arrow A. As such, the membrane 2 mentioned above above and is grossflachig, the membrane may be 2 are also printed by hand ball, at the same time the shower head is held by the front Übli ¬ cherweise the shower head is held with a flange on the pipe part 6b for actuation. The pressure point on the membrane 2 is not critical and a specific position does not have to be found. The reset takes place as mentioned by turning the cover 1. The turning is preferably carried out on the protruding nose lc. The shower head with WIP is largely closed and therefore visible protected against ingress of dirt. This is an important aspect, especially where there are special hygienic requirements.
Die Erfindung ermöglicht somit die Herstellung eines Brausekopfes, der aus vergleichsweise wenigen und robusten Teilen herstellbar ist und der sehr ergonomisch bedienbar und zudem funktionssicher ist. The invention thus enables the production of a shower head which can be produced from comparatively few and robust parts and which can be operated very ergonomically and is also functionally reliable.
