Description

Die Erfindung bezieht sich auf einen Brausekopf für Dusch- und Badeeinrichtungen, insbesondere Handbrause, mit einer mit der Wasserversorgung in Verbindung stehenden, wenigstens eine Austrittsöffnung aufweisenden Wasserzuflußkammer und einem nachgeschalteten, die Wasserstrahldüsen enthaltenden Brauseboden, wobei durch eine Relativbewegung des Brausebodens zum Gehäuse des Brausekopfes eine Umschaltung und/oder Veränderung der austretenden Brausestrahlen erfolgt, derart, daß wenigstens in einem Umschaltbereich eine Drosselung der zufließenden Wassermenge einstellbar ist.
Eine derartige Einrichtung ist aus der deutschen Patentschrift DE 30 47 336 C2 bekannt, wobei die Umstellung mit Hilfe eines in einer Hülse angeordneten Kolbens erfolgt, der axial bewegbar angeordnet und mit radialen Öffnungen in der Wandung der Hülse zusammenwirkt. Insbesondere wegen des verschiebbaren Kolbens benötigt diese Einrichtung einen axial relativ großen Platzbedarf, was insbesondere bei Handbrausen unerwünscht ist. Darüber hinaus ist bei dieser bekannten Einrichtung nur eine Umstellung zwischen zwei Brausestrahlerzeugungssystemen vorgesehen.The invention relates to a shower head for shower and bath facilities, in particular a hand shower, with a water inflow chamber which is connected to the water supply and has at least one outlet opening and a downstream shower base which contains the water jet nozzles, one by a relative movement of the shower base to the housing of the shower head Switching over and / or changing the emerging shower jets takes place in such a way that throttling of the inflowing amount of water can be set at least in a switching range.
Such a device is known from German patent DE 30 47 336 C2, the changeover being carried out with the aid of a piston arranged in a sleeve, which is arranged to be axially movable and cooperates with radial openings in the wall of the sleeve. In particular because of the displaceable piston, this device requires a relatively large amount of axial space, which is particularly undesirable for hand showers. In addition, in this known device there is only a changeover between two shower jet generation systems intended.

Der Erfindung liegt daher die Aufgabe zugrunde, die im Oberbegriff des Anspruchs 1 angegebene Umschaltvorrichtung zu verbessern und insbesondere so auszubilden, daß der benötigte Platzbedarf wesentlich verringert werden kann. Hierbei gehört es mit zur Aufgabe, die Umschalteinrichtung so zu gestalten, daß sie auch für die Umschaltung bei mehr als zwei Brausestrahlerzeugungssystemen einsetzbar ist.The invention is therefore based on the object of improving the switching device specified in the preamble of claim 1 and, in particular, of designing it in such a way that the required space can be significantly reduced. It is part of the task to design the switchover device in such a way that it can also be used for switchover in more than two shower jet generation systems.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Austrittsöffnung(en) in einer Trennwand parallel zur Mittelachse des Brausekopfes auf einem Lochkreis angeordnet ist(sind), an welche eine Wasserführungsscheibe, die eine oder mehrere an der stromaufwärtigen Stirnseite auf einem entsprechenden Lochkreis angeordnete Öffnungen hat, angelagert ist, wobei wenigstens eine Öffnung in Richtung des Lochkreisbogens von der Stirnseite eine als Drosselfläche wirkende Aussenkung oder eine Drosselkante aufweist, so daß über einen bestimmten Drehwinkelbereich eine stufenlose Drosselung der Wasserdurchströmmenge an dieser Öffnung einstellbar ist.
Weitere Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 9 angegeben.This object is achieved in that the outlet opening (s) are (are) arranged in a partition parallel to the central axis of the shower head on a bolt circle, to which a water guide disc has one or more openings arranged on the upstream end face on a corresponding bolt circle , is attached, wherein at least one opening in the direction of the bolt arc from the front side has a counterbore acting as a throttle surface or a throttle edge, so that a continuous throttling of the water flow rate at this opening can be set over a certain angle of rotation range.
Further refinements of the invention are specified in claims 2 to 9.

Mit diesen Maßnahmen wird erreicht, daß die Umschaltvorrichtung tellerartig flach gebaut werden kann. Die Öffnungen für den Wasserzustrom zu den einzelnen Brausestrahlerzeugungseinrichtungen können hierbei auf einem relativ großen Lochkreis angeordnet werden, so daß problemlos mehr als zwei separate Brausestrahlerzeugungseinrichtungen mit der erfindungsgemäßen Einrichtung geschaltet werden können. Auch für die an der Stirnfläche angeordneten Drosselflächen oder Drosselkanten im Bereich einer oder mehrerer Öffnungen der Wasserführungsscheibe ist genügend Platz vorhanden. Sie können relativ einfach, z.B. im Gießverfahren, eingebracht werden.With these measures it is achieved that the switching device can be built flat like a plate. The openings for the water inflow to the individual shower jet generating devices can be arranged on a relatively large bolt circle, so that more than two separate shower jet generating devices can be switched with the device according to the invention without any problems. Also for those at the There is sufficient space for throttle surfaces or throttle edges in the area of one or more openings in the water guide disk. They can be introduced relatively easily, for example in the casting process.

Vorteilhaft kann die erfindungsgemäße Umschalteinrichtung bei Handbrausen mit drei verschiedenen Brausestrahlerzeugungseinrichtungen, nämlich einer Einrichtung zur Erzeugung von mit Luft durchsetzten Brausestrahlen, einer Einrichtung zur Erzeugung von pulsierenden Brausestrahlen und einer Einrichtung zur Erzeugung von Normal- bzw. Vollbrausestrahlen, eingesetzt werden.
Zweckmäßig können hierbei für Vollbrausestrahlen zwei diametral gegenüberliegende Öffnungen in Form eines Radialschlitzes mit V-förmig zu beiden Seiten angeordneten Drosselflächen ausgebildet werden, wobei dich die Drosselflächen etwa über einen Winkel von 90o jeweils erstrecken können. Jeweils um 90o zu den Radialschlitzen versetzt, kann dann jeweils eine Öffnung in der Stirnfläche der Wasserführungsscheibe ausgebildet sein, die einerseits mit einer Einrichtung zur Erzeugung von Brausestrahlen aus einem Gemisch von Wasser und Luft und andererseits mit einer Einrichtung zur Erzeugung von pulsierenden Brausestrahlen verbunden ist. Alternativ können auch anstatt von Drosselflächen Drosselkanten an der Stirnseite vorgesehen werden, die vorzugsweise den Umfang der Stirnseite der Wasserführungsscheibe kurvenförmig begrenzen.
Die Öffnungen auf der Stirnseite der Wasserführungsscheibe sind dabei zweckmäßigerweise so plaziert, daß eine völlige Absperrung des Wasserdurchflusses nicht ermöglicht wird, um z.B. unzulässige Druckbelastungen im Brausekopf und der Zuführungsleitung zu vermeiden.The switching device according to the invention can advantageously be used in hand showers with three different shower jet generating devices, namely a device for generating shower jets interspersed with air, a device for generating pulsating shower jets and a device for generating normal or full shower jets.
Appropriately, two diametrically opposite openings in the form of a radial slot with V-shaped throttle surfaces can be formed for full shower jets, the throttle surfaces being able to extend over an angle of 90 ° in each case. In each case offset by 90 o to the radial slots, an opening can then be formed in the end face of the water guide disk, which is connected on the one hand to a device for generating shower jets from a mixture of water and air and on the other hand to a device for generating pulsating shower jets . Alternatively, instead of throttling surfaces, throttling edges can be provided on the end face, which preferably delimit the circumference of the end face of the water guide disc in a curved manner.
The openings on the face of the water guide disc are expediently placed so that a complete shut-off of the water flow is not possible, for example to avoid impermissible pressure loads in the shower head and the feed line.

Der Einfachheit halber sind bei den Ausführungsbeispielen in der Zeichnung gleiche oder entsprechende Elemente mit jeweils gleichen Bezugszeichen versehen.
Der in der Zeichnung der Figur 1 dargestellte Brausekopf ist Teil einer Handbrause, wobei der Handgriff mit dem Schlauchanschluß sich hinter der Zeichenebene befindet. Selbstverständlich kann der Brausekopf aber auch für eine Stationärbrause eingesetzt werden, wobei dann anstatt des Handgriffs ein koaxial zur Mittelachse 3 des Brausekopfes auszubildendes Anschlußteil für die Wasserversorgung vorzusehen ist.For the sake of simplicity, the same or corresponding elements are provided with the same reference numerals in the exemplary embodiments in the drawing.
The shower head shown in the drawing in FIG. 1 is part of a hand shower, the handle with the hose connection being located behind the plane of the drawing. Of course, the shower head can also be used for a stationary shower, in which case, instead of the handle, a connection part to be provided coaxially with the central axis 3 of the shower head must be provided for the water supply.

Bei dem in Figur 1 gezeigten Brausekopf ist stromaufwärts eine Wasserzuführungskammer 1 angeordnet, die durch das in der Zeichnung nicht dargestellte Griffstück geführt ist und eine Anschlußmöglichkeit für die Schlauchleitung aufweist. An der stromabwärts gelegenen Seite der Wasserzuführungskammer 1 ist ein Haltezapfen 11 koaxial zur Mittelachse 3 des Brausekopfes eingeschweißt. Auf dem Haltezapfen 11 ist eine als Dichtscheibe wirkende Trennwand 10 unverdrehbar angeordnet. Die Trennwand 10 hat auf einem Lochkreis 102 eine Austrittsöffnung 11 mit elliptischem Querschnitt, wie es beispielsweise aus Figur 3 der Zeichnung zu entnehmen ist.
An der stromabwärts gelegenen Stirnseite der Trennwand 10 ist eine Wasserführungsscheibe 2 drehbar auf dem Haltezapfen 11 angelagert, wobei die Axialsicherung von einer in den Haltezapfen 11 einschraubbaren Befestigungsschraube 20 hergestellt ist. Die Wasserführungsscheibe 2 hat auf einem entsprechenden Lochkreis 102 an der stromaufwärts gelegenen Stirnseite vier symmetrisch zueinander angeordnete Öffnungen zur Abführung des zufließenden Brausewassers, wie es aus den Figuren 3,5,7 und 9 zu entnehmen ist. Zwei diametral gegenüberliegende Öffnungen sind als Radialschlitze 22 in der Stirnfläche eingelassen, wobei zu beiden Seiten eine schräg angeordnete Drosselfläche 21 ausgebildet ist. Jeder der Radialschlitze 22 streckt sich zusammen mit den beiden Drosselflächen 21 über einen Winkelbereich von 90o. Die maximale Tiefe bzw. Einsenkung der Drosselflächen 21 beträgt etwa 0,3 der Breite des Radialschlitzes 22.
Um 90o versetzt zu den beiden diametral angeordneten Radialschlitzen 22 befindet sich jeweils ein entsprechend dem Querschnitt der Austrittsöffnung 101 ausgebildeter Einlaß 23,24. Konzentrisch zu den beiden Einlässen 23,24 ist in der Stirnseite jeweils eine Nut 25 zur Aufnahme eines O-Rings 26 eingelassen.
An dem stromabwärts gelegenen Bereich der Wasserführungsscheibe 2 ist konzentrisch zur Mittelachse 3 eine Ringkammer 4 mit Strahldüsen 42 zur Erzeugung eines Normal- oder Vollbrausestrahles vorgesehen. Konzentrisch zur äußeren Ringkammer 4 ist eine weitere Ringkammer 5, in der Düsen 52 zur Erzeugung von Brausestrahlen, die aus einem Gemisch von Wasser und Luft bestehen, vorgesehen. Schließlich ist zentral am stromabwärts gelegenen Bereich der Wasserführungsscheibe 2 eine Kammer 6 ausgebildet, in der eine Vorrichtung mit Düsen 62 zur Erzeugung von pulsierend austretenden Brausestrahlen angeordnet ist.In the shower head shown in Figure 1, a water supply chamber 1 is arranged upstream, which is guided through the handle, not shown in the drawing, and has a connection option for the hose line. On the downstream side of the water supply chamber 1, a retaining pin 11 is welded in coaxially to the central axis 3 of the shower head. On the retaining pin 11, a partition 10 acting as a sealing washer is non-rotatably arranged. The dividing wall 10 has an outlet opening 11 with an elliptical cross section on a bolt circle 102, as can be seen, for example, from FIG. 3 of the drawing.
On the downstream end of the partition 10, a water guide disc 2 is rotatably mounted on the holding pin 11, the axial securing device being produced by a fastening screw 20 which can be screwed into the holding pin 11. The water guide disc 2 has, on a corresponding bolt circle 102 on the upstream end face, four openings arranged symmetrically to one another for the discharge of the incoming shower water, as can be seen from FIGS. 3, 5, 7 and 9. Two diametrically opposed openings are made as radial slots 22 in the end face, an obliquely arranged throttle face 21 being formed on both sides. Each of the radial slots 22 extends together with the two throttle surfaces 21 over an angular range of 90 ° . The maximum depth or depression of the throttle surfaces 21 is approximately 0.3 the width of the radial slot 22.
Offset by 90 ° to the two diametrically arranged radial slots 22 there is an inlet 23, 24 designed in accordance with the cross section of the outlet opening 101. Concentric to the two inlets 23, 24 there is a groove 25 in the end face for receiving an O-ring 26 embedded.
An annular chamber 4 with jet nozzles 42 for generating a normal or full spray jet is provided on the downstream region of the water guide disc 2 concentrically with the central axis 3. A further annular chamber 5, in which nozzles 52 for generating shower jets, which consist of a mixture of water and air, is provided concentrically with the outer annular chamber 4. Finally, a chamber 6 is formed centrally on the downstream region of the water guide disc 2, in which a device with nozzles 62 for generating pulsating shower jets is arranged.

Der Brausekopf hat folgende Funktionsweise:
In der in Figur 1 gezeigten Drehstellung der Wasserführungsscheibe 2 tritt das zuströmende Brausewasser durch die Austrittsöffnung 101 der Trennwand 10 hindurch, wobei die Austrittsöffnung 101 sich senkrecht über einem Radialschlitz 22 befindet, wie es insbesondere aus Figur 3 und 2 der Zeichnung zu entnehmen ist. Das zuströmende Wasser wird hierbei in dem Radialschlitz 22 radial nach außen umgelenkt und gelangt hierbei entsprechend der Pfeile 7 über einen Zulaufkanal 41 in die Ringkammer 4. Von hier aus wird das zugeführte Wasser über die ringförmig über den Brausebodenbereich 71 geordneten Strahldüsen 42 als Voll- oder Normalbrausestrahlen abgegeben. In dieser, insbesondere aus Figur 2 und 3 zu entnehmenden Stellung befindet sich die Austrittsöffnung 101 in der maximalen Öffnungsstellung. Wird nun mit Hilfe seiner Seitenfläche der Brauseboden 71 gedreht, so gelangt die Austrittsöffnung 101 verstärkt auf eine der Drosselfächen 21, so daß nunmehr zunehmend eine Reduzierung der Wasserdurchflußmenge erreicht wird, wie es insbesondere aus der Zeichnung Figur 4 und 5 zu entnehmen ist. Durch die wahlweise einstellbare Drosselung der Wasserdurchflußmenge kann der Normal- oder Vollbrausestrahl in seiner Härte variiert werden. Es ist somit durch die stufenlose Durchflußregulierung möglich, von weichen bis zu harten, eine hohe Austrittsgeschwindigkeit aufweisende Normal- oder Vollbrausestrahlen zu erzeugen.
Sollen dagegen Brausestrahlen aus einem Gemisch von Wasser und Luft erzeugt werden, so ist die Wasserführungsscheibe 2 mit Hilfe der Seitenwandung des Brausebodens 71 in eine Stellung zu verdrehen, wie sie aus Figur 8 und 9 der Zeichnung zu entnehmen ist. In dieser Drehstellung befindet sich die Austrittsöffnung 101 senkrecht über dem Einlaß 23. Mit dem O-Ring 26 ist hierbei eine Abdichtung zu den anderen Strahlerzeugungssystemen des Brausekopfes bewerkstelligt. Das über die Austrittsöffnung 101 zugeführte Wasser gelangt somit in Richtung des Pfeils 7 unmittelbar in einen Zulaufkanal 51 und von hier aus in die Ringkammer 5. Das zugeführte Brausewasser wird hiernach als Brausestrahlen, die aus einem Wasser-Luft-Gemisch bestehen, von den Düsen 52 ins Freie abgegeben.
Soll alternativ ein pulsierender Brausestrahl mit dem Brausekopf erzeugt werden, so ist die Wasserführungsscheibe mit Hilfe der Seitenfläche des Brausebodens 71 in eine Drehstellung zu bewegen, wie sie aus Figur 6 und 7 der Zeichnung zu entnehmen ist. In dieser Stellung befindet sich die Austrittsöffnung 101 senkrecht über dem Einlaß 24. Die Abdichtung zu den anderen Brausestrahlerzeugungseinrichtungen erfolgt hierbei mit dem O-Ring 26. Das herangeführte Brausewasser wird somit in Richtung des Pfeils 7 über die Austrittsöffnung 101 direkt durch einen Zulaufkanal 61 der Kammer 6 zugeleitet und von hier über die Düsen 62 als pulsierende Brausestrahlen abgegeben. Die auf der Stirnseite der Wasserführungsscheibe 2 ausgebildeten Öffnungen, nämlich die beiden Radialschlitze 22 mit den zugehörigen Drosselflächen 21 und den Einlässen 23,24, sind so angeordnet, daß in jeder Drehstellung eine Mindestmenge von Brausewasser aus dem Brausekopf austreten kann. Hierdurch ist sichergestellt, daß unzulässige Druckbelastungen im Bereich des Brausekopfes und der Brausewasserzuführung sowie durch eine schnelle Umstellung erzeugte Wasserschläge vermieden werden. Andererseits ist aber durch die Anordnung der Dichtringe 26 im Bereich der Einlässe 24 und 23 sichergestellt, daß jede Brausestrahlerzeugungseinrichtung des Brausekopfes separat betrieben werden kann, ohne daß Leckwasser über die anderen Strahlerzeugungseinrichtungen austritt.The shower head works as follows:
In the rotational position of the water guide disc 2 shown in FIG. 1, the inflowing shower water passes through the outlet opening 101 of the partition 10, the outlet opening 101 being located vertically above a radial slot 22, as can be seen in particular from FIGS. 3 and 2 of the drawing. The inflowing water is in this case deflected radially outward in the radial slot 22 and in this case reaches the annular chamber 4 via an inlet channel 41 in accordance with the arrows 7. From here, the water supplied is discharged via the jet nozzles 42 arranged in a ring over the shower base area 71 as full or Normal shower jets emitted. In this position, which can be seen in particular from FIGS. 2 and 3, the outlet opening 101 is in the maximum opening position. If the shower base 71 is now rotated with the aid of its side surface, the outlet opening 101 reaches one of the throttle surfaces 21, so that a reduction in the water flow rate is now increasingly achieved, as is shown in particular in the drawing Figures 4 and 5 can be seen. The hardness of the normal or full shower spray can be varied through the optionally adjustable throttling of the water flow rate. The infinitely variable flow regulation makes it possible to produce normal or full shower jets from soft to hard, with a high exit speed.
If, on the other hand, shower jets are to be generated from a mixture of water and air, the water guide disc 2 is to be turned into a position by means of the side wall of the shower base 71, as can be seen in FIGS. 8 and 9 of the drawing. In this rotational position, the outlet opening 101 is located vertically above the inlet 23. In this case, the O-ring 26 seals the other jet generation systems of the shower head. The water supplied via the outlet opening 101 thus arrives directly in the direction of arrow 7 into an inlet channel 51 and from here into the annular chamber 5. The shower water supplied is then from the nozzles 52 as shower jets, which consist of a water-air mixture released into the open.
If, alternatively, a pulsating shower jet is to be generated with the shower head, the water guide disc is to be moved into a rotational position with the aid of the side surface of the shower base 71, as can be seen in FIGS. 6 and 7 of the drawing. In this position, the outlet opening 101 is located vertically above the inlet 24. The sealing to the other shower jet generating devices takes place here with the O-ring 26. The shower water introduced is thus in the direction of arrow 7 via the outlet opening 101 directly through an inlet channel 61 of the chamber 6 fed and emitted from here via the nozzles 62 as pulsating shower jets. The openings formed on the end face of the water guide disk 2, namely the two radial slots 22 with the associated throttle surfaces 21 and the inlets 23, 24, are arranged such that a minimum amount of shower water can escape from the shower head in each rotational position. This ensures that impermissible pressure loads in the area of the shower head and the shower water supply as well as water hammer generated by a quick changeover are avoided. On the other hand, the arrangement of the sealing rings 26 in the area of the inlets 24 and 23 ensures that each shower jet generating device of the shower head can be operated separately without leak water escaping through the other jet generating devices.

In den Figuren 10 bis 13 ist eine abgewandelte Ausführung der Wasserführungsscheibe 2 gezeigt. Anstatt der Radialschlitze 22 mit den zugehörigen Drosselflächen 21 sind an der Stirnflächenwandung kurvenförmige Drosselkanten 210 ausgebildet, die in Abhängigkeit von der Drehstellung über einen bestimmten Drehwinkel eine etwa stetige Verringerung bzw. Vergrößerung des Durchgangsquerschnitts der Austrittsöffnung 101 ermöglicht. In den Figuren 10 und 11 ist der Durchgangsquerschnitt in der voll geöffneten, in den Figuren 12 und 13 in einer gedrosselten Stellung dargestellt. Der Drosselvorgang erstreckt sich hierbei etwa über einen Drehwinkel von 60o.A modified embodiment of the water guide disk 2 is shown in FIGS. 10 to 13. Instead of the radial slots 22 with the associated throttle surfaces 21, curvilinear throttle edges 210 are formed on the end face wall, which, depending on the rotational position, enables an approximately continuous reduction or enlargement of the passage cross section of the outlet opening 101 as a function of the rotational position. FIGS. 10 and 11 show the passage cross section in the fully open position, in FIGS. 12 and 13 in a throttled position. The throttling process extends approximately over an angle of rotation of 60 ° .
