Abstract

In a shower head for producing pulsating fluid jets with a rotating ball for the periodic sealing of the individual fluid outlet openings on the shower head, it is proposed for the sake of improvement and for the use as a sanitary hand-held or stationary shower fitting that the ball be arranged in an annular channel constructed on a shower floor and the annular channel be bounded by a nozzle plate at the region located upstream, the cross-section of the individual fluid outlet openings being larger than that of the individual nozzles for the fluid inlet. <IMAGE>

Description

Die Erfindung betrifft einen Brausekopf zur Erzeugung von pulsierenden Fluidstrahlen, insbesondere für Wassermassagen, mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen.
Ein derartiger Brausekopf ist aus der US-A-4 089 471 bekannt. Hierbei ist lediglich eine Flüssigkeitseinlaßöffnung mit entsprechend großem Querschnitt vorgesehen, was zu Funktionsstörungen, insbesondere beim Anlaufen der Kugel, führen kann.
Ferner ist aus der DE-A-33 33 327 ein Brause bekannt, bei der die Brausestrahlen radial bzw. sternförmig aus dem zylindrischen Mantel des Brausekopfes austreten. Durch die Strahlaustrittsrichtung dürfte diese Brause für den Einsatz als sanitäre Hand- oder Stationärbrause wenig geeignet sein.
Schließlich ist es bei Mundduschen bekannt, in dem Spritzkopf einen Ringkanal mit einer umlaufenden Kugel vorzusehen, wobei die Fluideinführung tangential und der Fluidaustritt koaxial aus dem Ringkanal erfolgt (US-A-3 736 923).The invention relates to a shower head for generating pulsating fluid jets, in particular for water massages, with the features specified in the preamble of claim 1.
Such a shower head is known from US-A-4 089 471. In this case, only a liquid inlet opening with a correspondingly large cross section is provided, which can lead to malfunctions, in particular when the ball starts up.
Furthermore, from DE-A-33 33 327 a shower is known in which the shower jets emerge radially or in a star shape from the cylindrical jacket of the shower head. Due to the direction of the jet, this shower should not be very suitable for use as a sanitary hand or stationary shower.
Finally, it is known for oral irrigators to provide an annular channel with a circumferential ball in the spray head, the fluid being introduced tangentially and the fluid exiting coaxially from the annular channel (US Pat. No. 3,736,923).

Der Erfindung liegt die Aufgabe zugrunde, den Brausekopf nach dem Oberbegriff des Anspruchs 1 zu verbessern und so auszubilden, daß bei dem Einsatz als sanitäre Hand- oder Stationärbrause eine optimale Funktionstüchtigkeit und eine relativ lange Gebrauchsdauer ermöglicht wird.The invention has for its object to improve the shower head according to the preamble of claim 1 and to design such that when used as a sanitary hand or stationary shower an optimal functionality and a relatively long service life is made possible.

Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruchs 1 gelöst.
Weitere Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 9 angegeben.
Durch die Anordnung mehrerer Düsen in der den Ringkanal auf dem Brauseboden stromaufwärts begrenzenden Düsenscheibe wird eine gute Abdichtung der Fluidaustrittsöffnungen mit der Kugel erreicht, wobei insbesondere durch die erfindungsgemäße Richtung der Fluidströmung ein Aufschwimmen der Kugel in dem Ringkanal vermieden wird. Durch ein Aufschwimmen der Kugel im Ringkanal wird nämlich die Absperr- oder Unterbrecherwirkung der Kugel zu den Fluidaustrittsöffnungen vermindert oder gar aufgehoben.This object is achieved with the features of claim 1.
Further refinements of the invention are specified in claims 2 to 9.
The arrangement of a plurality of nozzles in the nozzle disk which delimits the annular channel on the shower floor upstream provides a good seal of the fluid outlet openings with the ball, the floating of the ball in the annular channel being avoided in particular by the direction of the fluid flow according to the invention. By floating the ball in the ring channel, the shut-off or interruption effect of the ball to the fluid outlet openings is reduced or even canceled.

Bei den in der Zeichnung dargestellten Ausführungsbeispielen sind der Einfachheit halber gleiche oder entsprechende Elemente mit jeweils gleichen Bezugszeichen versehen.
Der in den Figuren 1 bis 3 schematisch dargestellte Brausekopf 1 besteht im wesentlichen aus einem Gehäuse mit einer Wassereinlaßöffnung 10, einem Brauseboden 2 mit einem Ringkanal 3, einer Kugel 5 sowie einer Düsenscheibe 4. Der etwa im Maßstab 2 : 1 dargestellte Brausekopf 1 kann sowohl als Stationärbrause als auch als Handbrause eingesetzt werden. Der Brauseboden 2 ist dabei zum Teil mit der Wassereinlaßöffnung 10 mittels Gewinde 11 dicht verbunden. In dem Brauseboden 2 ist konzentrisch zur Mittelachse des Brausekopfes 1 der Ringkanal 3 ausgebildet. Im Boden des Ringkanals 3 ist eine Rollbahn 31 für die Kugel 5 zur umlaufenden Absperrung von Fluidaustrittsöffnungen 30 vorgesehen, so daß jeweils ein intermittierender Wasserstrahl zu Dusch- und Massagezwecken erzeugt wird. Die Rollbahn 31 ist dabei torusförmig, entsprechend dem Durchmesser der Kugel 5, ausgebildet und hat eine Breite, die etwa dem doppelten Durchmesser der Fluidaustrittsöffnungen 30 entspricht. An der stromaufwärts gelegenen Seite ist der Ringkanal 3 von der Düsenscheibe 4 verschlossen, in der für den Wassereinlaß ausgebildete Düsen 40 angeordnet sind. Die als Bohrungen ausgebildete Düsen 40 haben eine Neigung 41 zur Mittelachse des Brausekopfes 1 von etwa 15°, wie es aus der Figur 3 zu entnehmen ist.
Eine besonders günstige, durch Versuche bestätigte Dimensionierung des Brausekopfes 1 kann dadurch erzielt werden, wenn der mittlere Durchmesser 32 des Ringkanals 3 etwa 20 mm beträgt und die Kugel 5 einen Durchmesser von etwa 10 mm aufweist. Die Kugel 5 sollte hierbei im Ringkanal 3 mit geringem Spiel geführt sein, wobei das Spiel zwischen Düsenscheibe 4 und der Rollbahn 31 des Brausebodens 2 zwischen 1/10 bis 3/10 mm betragen kann. Für die Brausestrahlerzeugung sind fünf symmetrisch angeordnete Fluidaustrittsöffnungen 30 in der Rollbahn 31 als Bohrungen mit einem Durchmesser von 2,5 mm und einer Bohrungslänge von etwa 6 mm ausgebildet. In der Düsenscheibe 4 sind ebenfalls auf einem Kreisring mit einem Durchmesser 32 zwölf symmetrisch angeordnete, als Bohrungen ausgebildete Düsen 40 mit einem Durchmesser von 2 mm und einer Neigung 41 von 15° vorgesehen.
Mit dem vorstehend beschriebenen Brausekopf 1 können bei einem Fließdruck von 1 bis 3 bar des zugeführten Brausewassers etwa 50 bis 100 Umläufe pro Sekunde der Kugel 5 in dem Ringkanal 3 erzeugt werden, so daß die Fluidaustrittsöffnungen 30 umlaufend von der Kugel 5 verschlossen und wieder freigegeben werden, was eine intermittierende Abgabe von Brausestrahlen aus den Fluidaustrittsöffnungen 30 verursacht und den Pulsationseffekt des Strahlbildes bewirkt. Durch die torusförmig ausgebildete Rollbahn 31 und der etwa parallel zur Mittelachse des Brausekopfes 1 gerichteten Wasserströme wird eine optimale intermittierende Abdichtung der Fluidaustrittsöffnungen 30 erreicht.In the exemplary embodiments shown in the drawing, the same or corresponding elements are provided with the same reference numerals for the sake of simplicity.
The shower head 1 shown schematically in FIGS. 1 to 3 essentially consists of a housing with a water inlet opening 10, a shower base 2 with an annular channel 3, a ball 5 and a nozzle disk 4. The shower head 1, shown approximately on a scale of 2: 1, can be both can be used as a stationary shower as well as a hand shower. The shower base 2 is partially tightly connected to the water inlet opening 10 by means of thread 11. In the shower base 2, the ring channel 3 is formed concentrically to the central axis of the shower head 1. In the bottom of the ring channel 3, a roller track 31 is provided for the ball 5 for the circumferential blocking of fluid outlet openings 30, so that an intermittent water jet is generated for showering and massage purposes. The runway 31 is toroidal, corresponding to the diameter of the ball 5, and has a width which is approximately twice the diameter of the fluid outlet openings 30 corresponds. On the upstream side, the ring channel 3 is closed by the nozzle disk 4, in which nozzles 40 designed for the water inlet are arranged. The nozzles 40 designed as bores have an inclination 41 to the central axis of the shower head 1 of approximately 15 °, as can be seen from FIG. 3.
A particularly favorable dimensioning of the shower head 1, as confirmed by tests, can be achieved if the average diameter 32 of the ring channel 3 is approximately 20 mm and the ball 5 has a diameter of approximately 10 mm. The ball 5 should be guided in the ring channel 3 with little play, the play between the nozzle disc 4 and the runway 31 of the shower base 2 being between 1/10 to 3/10 mm. For the shower jet generation, five symmetrically arranged fluid outlet openings 30 in the runway 31 are designed as bores with a diameter of 2.5 mm and a bore length of approximately 6 mm. In the nozzle disk 4, twelve symmetrically arranged nozzles 40, designed as bores and having a diameter of 2 mm and an inclination 41 of 15 °, are likewise provided on a circular ring with a diameter 32.
With the shower head 1 described above, at a flow pressure of 1 to 3 bar of the supplied shower water, about 50 to 100 revolutions per second of the ball 5 can be generated in the ring channel 3, so that the fluid outlet openings 30 are closed all around by the ball 5 and released again , which causes an intermittent delivery of shower jets from the fluid outlet openings 30 and causes the pulsation effect of the jet image. An optimal intermittent sealing of the fluid outlet openings 30 is achieved by means of the toroidal roller conveyor 31 and the water flows directed approximately parallel to the central axis of the shower head 1.

Zweckmäßig wird hierbei die Kugel 5 aus Polypropylen hergestellt. Mit Vorteil kann auch die Rollbahn 31 mit den Fluidaustrittsöffnungen 30 aus einem gummielastischen Material hergestellt werden.The ball 5 is expediently made of polypropylene. The runway 31 with the fluid outlet openings 30 can also advantageously be produced from a rubber-elastic material.

Das in Figur 4 gezeigte Ausführungsbeispiel beinhaltet einen Brausekopf 1, der für eine stationäre Anordnung an einer Gebäudewand etc. vorgesehen ist. Der Brausekopf 1 ist dabei mit einer Umstellvorrichtung 7 versehen, mittels der das zuströmende Brausewasser verschiedenen Strahlerzeugungssystemen zugeführt werden kann. Der Brausekopf 1 mit seiner Umstellvorrichtung 7 entspricht weitgehend dem in der deutschen Patentschrift DE-C-30 47 336 gezeigten Brausekopf, wobei jedoch der Brauseboden 2 entsprechend der Erfindung ausgebildet ist.
Das Brausewasser wird über ein Anschlußstück 12 dem Brausekopf 1 zugeführt und über Einlaßöffnungen 13 der Umstellvorrichtung 7 zugeleitet.
Die Umstellung erfolgt dabei mit einem Hohlkolbenschieber 14, so daß einerseits eine zentral im Brauseboden 2 angeordnete Fluidaustrittsdüse 6 mit dem zuströmenden Wasser versorgt wird und einen kontinuierlich austretenden Brausestrahl erzeugt, wie es in der rechten Hälfte der Figur 4 dargestellt ist. In einer anderen Stellung des Hohlkolbenschiebers 14, wie er in der linken Bildhälfte der Figur 4 dargestellt ist, wird dagegen nur der im Brauseboden 2 ausgebildete Ringkanal 3 mit Wasser versorgt. Der Brauseboden 2 ist hierbei mit dem Hohlkolbenschieber 14 festverbunden, so daß er entsprechend dem Hohlkolbenschieber 14 die Axialbewegungen mit vollführt. In der voll in den Brausekopf 1 eingeschobenen Stellung, wie sie in der linken Bildhälfte Figur 4 dargestellt ist, greift dabei ein als Gehäusestift ausgebildetes Glied 35 durch eine Öffnung 42 in den Ringkanal 3 ein und stoppt die umlaufende Kugel 5 in einer derartigen Stellung, daß in allen Fluidaustrittsöffnungen 30 kontinuierlich Brausestrahlen erzeugt werden können. In dieser Stellung wird somit der bekannte, kontinuierlich austretende Vollbrausestrahl erzeugt.
Wird dagegen der Brauseboden 2 mit Hilfe der Umstellvorrichtung 7 um einen Teilbereich aus dem Brausekopf 1 herausgeschoben, so gibt das Glied 35 den Umlauf für die Kugel 5 frei, jedoch befindet sich der Hohlkolbenschieber 14 noch in einer Position, daß das gesamte zufließende Brausewasser über die Einlaßöffnungen 13 dem Ringkanal 3 zugeführt wird, so daß nunmehr pulsierend umlaufende Brausestrahlen aus den Fluidaustrittsöffnungen 30 abgegeben werden. Erst danach, wenn mit der Umstellvorrichtung 7 der Brauseboden 2 weiter aus dem Brausekopf 1 herausgeschoben wird, erfolgt eine Umstellung des zufließenden Brausewassers, wie es aus der rechten Bildhälfte Figur 4 zu entnehmen ist.The exemplary embodiment shown in FIG. 4 includes a shower head 1, which is provided for a stationary arrangement on a building wall, etc. The shower head 1 is provided with a changeover device 7, by means of which the inflowing shower water can be supplied to various jet generation systems. The shower head 1 with its changeover device 7 largely corresponds to the shower head shown in German Patent DE-C-30 47 336, but the shower base 2 is designed in accordance with the invention.
The shower water is fed to the shower head 1 via a connector 12 and fed to the changeover device 7 via inlet openings 13.
The changeover is carried out with a hollow piston valve 14, so that on the one hand a fluid outlet nozzle 6 arranged centrally in the shower base 2 is supplied with the inflowing water and generates a continuously escaping shower jet, as shown in the right half of FIG. In a different position of the hollow piston valve 14, as shown in the left half of FIG. 4, only the annular channel 3 formed in the shower base 2 is supplied with water. The shower base 2 is firmly connected to the hollow spool 14 so that it carries out the axial movements in accordance with the hollow spool 14. In the position fully pushed into the shower head 1, as shown in the left half of FIG. 4, a link 35 designed as a housing pin engages through an opening 42 in the annular channel 3 and stops the rotating ball 5 in such a position that shower jets can be generated continuously in all fluid outlet openings 30. In this position, the well-known, continuously emerging full shower jet is thus generated.
If, on the other hand, the shower base 2 is pushed out of the shower head 1 by a partial area with the aid of the changeover device 7, the link 35 releases the circulation for the ball 5, but the hollow piston slide 14 is still in a position such that the entire inflowing shower water is above the Inlet openings 13 are fed to the ring channel 3, so that now pulsating shower jets are now emitted from the fluid outlet openings 30. Only after this, when the shower base 2 is pushed further out of the shower head 1 with the changeover device 7, does the incoming shower water change over, as can be seen from the right half of the figure in FIG.
