Description
Die Erfindung geht aus von einer Massagebrause, mit deren Hilfe ein oder mehrere pulsierende Wasserstrahlen erzeugt werden können.The invention is based on a massage shower, with the help of one or more pulsating water jets can be generated.
Es ist bereits eine solche Massagebrause bekannt (DE-A1 2911405). Bei dieser bekannten Massagebrause kann die Frequenz der Pulsation der pulsierenden Wasserstrahlen dadurch verändert werden, daß der Abstand zwischen einem ein Verschlußelement aufweisenden Rotor und der Strahlscheibe verändert werden kann. Wenn der Rotor mit seiner Verschlußplatte direkt auf der Strahlscheibe aufliegt, wird er bei der Rotation gebremst. Wird nun die Strahlscheibe axial bewegt, so verringert sich die Anpressung des Rotors, was zu einer Vergrößerung der Rotationsgeschwindigkeit und damit zu einer Erhöhung der Frequenz der Pulsationen führt. Wenn schließlich der Rotor außer Eingriff mit der Strahlscheibe gelangt, wird die maximale Frequenz erreicht. Da sich hier allerdings der Abstand zwischen dem Verschlußelement und den Strahlaustrittsöffnungen ändert, führt eine solche Verstellung gleichzeitig auch zu einer Änderung der Charakteristik der Strahlen, die mit zunehmendem Abstand zwischen der Strahlscheibe und dem Verschlußelement weicher werden. Außerdem entsteht bei der niedrigen Frequenz eine Gleitreibung zwischen zwei Teilen, die zu Abnutzungserscheinungen führt.It is already such a massage shower known (DE-A1 2911405). In this known massage shower the frequency of the pulsation of the pulsating water jets can be changed by the fact that the distance between a shutter member having a rotor and the jet disk can be changed. If the rotor with its closure plate rests directly on the jet disk, it is braked during the rotation. Now, if the jet disk is moved axially, so reduces the contact pressure of the rotor, which leads to an increase in the rotational speed and thus to an increase in the frequency of the pulsations. Finally, when the rotor disengages from the jet disk, the maximum frequency is reached. However, since here the distance between the closure element and the jet outlet openings changes, such adjustment also leads to a change in the characteristic of the beams, with increasing distance between the jet disk and soften the closure element. In addition, at the low frequency, a sliding friction between two parts, resulting in wear and tear.
Es ist bereits eine Massagebrause bekannt, bei der zur Erzeugung eines pulsierenden Wasserstrahls ein Rotor vorhanden ist, der Strahlaustrittsöffnungen abwechselnd öffnet und schließt. Zur Änderung der Frequenz des Massagestrahls wird die Menge des den Rotor antreibenden Wassers durch eine Querschnittsveränderung der Wasserstrahlen erreicht.There is already known a massage shower, in which a rotor is present to produce a pulsating water jet, the jet outlet openings alternately opens and closes. To change the frequency of the massage jet, the amount of water driving the rotor is achieved by a change in the cross section of the water jets.
Eine solche Massagebrause ist auch durch die US-A- 3,801,019 bekannt.Such a massage shower is also known from US-A-3,801,019.
Der Erfindung liegt die Aufgabe zugrunde, eine Massagebrause zu schaffen, die bei einfachem Aufbau eine Änderung der Frequenz der Pulsationen des mindestens einen Wasserstrahls ermöglicht.The invention has for its object to provide a massage shower, which allows a simple structure, a change in the frequency of the pulsations of the at least one water jet.
Zur Lösung dieser Aufgabe schlägt die Erfindung eine Massagebrause mit den im Anspruch 1 genannten Merkmalen vor. Weiterbildungen der Erfindung sind Gegenstand von Unteransprüchen, deren Wortlaut durch Bezugnahme zum Inhalt der Beschreibung gemacht wird.To solve this problem, the invention proposes a massage shower with the features mentioned in claim 1. Further developments of the invention are the subject of subclaims, the wording of which is incorporated by reference into the content of the description.
Bei den bisher bekannten Massagebrausen ist natürlich die Frequenz des Rotors in gewissem Ausmaß von der Menge des in die Brause einströmenden Wassers abhängig. Die Erfindung schlägt nun vor, die Einrichtung zur Änderung der Frequenz derart auszubilden, daß sie die Frequenz der Pulsation des Wasserstrahls ohne eine Änderung der einströmenden Wassermenge ändert.In the previously known massage showers of course, the frequency of the rotor is dependent to some extent on the amount of water flowing into the shower water. The invention now proposes to form the means for changing the frequency such that it changes the frequency of the pulsation of the water jet without a change in the inflowing amount of water.
Es ist selbstverständlich auch denkbar, die Frequenz der Pulsation der pulsierenden Wasserstrahlen dadurch zu ändern, daß, wie dies im Stand der Technik auch bekannt ist, ein Teil des Wassers zu einer anderen Strahlaustrittsöffnung geleitet wird, die keinen pulsierenden Wasserstrahl erzeugt. Damit läßt sich dann auch eine Änderung der Pulsation erreichen, indem der Wasserstrahl einfach weniger Wasser erhält. Die Erfindung schlägt statt dessen vor, die Einrichtung zur Änderung der Frequenz der Pulsation des Wasserstrahls derart auszubilden, daß sie die Frequenz des Wasserstrahls ohne Änderung der Menge des Wassers des pulsierenden Wasserstrahls ändert.It is of course also conceivable to change the frequency of the pulsation of the pulsating water jets in that, as is also known in the prior art, a part of the water is passed to another jet outlet opening which does not generate a pulsating water jet. This can then also achieve a change in the pulsation by the water jet simply receives less water. The invention instead proposes to design the means for changing the frequency of the pulsation of the water jet so that it changes the frequency of the water jet without changing the amount of water of the pulsating water jet.
In nochmaliger Weiterbildung der Erfindung kann vorgesehen sein, daß bei der Massagebrause die Frequenz der Pulsation geändert wird, ohne den Charakter des pulsierenden Wasserstrahls zu ändern, d. h., daß der Wasserstrahl seine Härte beibehalten soll. Selbsverständlich kann es auch möglich sein, eine getrennte Einrichtung zur Änderung der Härte des Wasserstrahls vorzusehen, die dann aber unabhängig von der Verstellung der Frequenz arbeitet.In a further development of the invention can be provided that in the massage shower the frequency of the pulsation is changed without changing the character of the pulsating water jet, d. h., That the water jet should maintain its hardness. Of course, it may also be possible to provide a separate means for changing the hardness of the water jet, but then working independently of the adjustment of the frequency.
Der pulsierende Wasserstrahl wird dadurch erzeugt, daß die Massagebrause einen mit mindestens einem Flügel versehenen Rotor aufweist, der durch eine Wasserströmung drehantreibbar ist und mit einem Verschlußelement die Strahlaustrittsöffnung abwechselnd öffnet und verschließt.The pulsating water jet is generated by the fact that the massage shower has a rotor provided with at least one wing, which is rotatably driven by a water flow and with a closure element, the jet outlet opening alternately opens and closes.
Die Antriebsströmung zum Antreiben des Rotors kann in Weiterbildung der Erfindung durch mindestens einen nicht radial bezüglich der Drehachse des Rotors verlaufenden Wasserstrahl gebildet werden. Ein radialer Wasserstrahl würde kein Drehmoment zum Drehantrieb des Rotors liefern. Der Wasserstrahl kann insbesondere axial verlaufen, wenn die Flügel des Rotors ähnlich wie bei einer Schiffsschraube ausgebildet sind.The drive flow for driving the rotor can be formed in a further development of the invention by at least one non-radial with respect to the axis of rotation of the rotor extending water jet. A radial jet of water would not provide torque to rotationally drive the rotor. In particular, the jet of water may be axial when the blades of the rotor are similar to a ship's propeller.
Es ist aber auch möglich, daß der mindestens eine Wasserstrahl in der Drehebene des Rotors schräg gegenüber einem Radius bis tangential verläuft.But it is also possible that the at least one jet of water in the plane of rotation of the rotor obliquely opposite to a radius to tangential.
In Weiterbildung der Erfindung kann vorgesehen sein, daß die Drehantriebsstrahlen durch schräg gegenüber einem Radius bezüglich der Drehachse des Rotors verlaufende Schlitze gebildet werden. Dabei verlaufen die Schlitze natürlich alle in der gleichen Richtung schräg, da ja die dadurch erzeugten Strahlen den Rotor antreiben sollen.In a further development of the invention can be provided that the rotary drive beams are formed by obliquely opposite to a radius with respect to the axis of rotation of the rotor extending slots. Of course, the slits all run obliquely in the same direction, since the beams generated thereby are supposed to drive the rotor.
Zur Änderung der Frequenz der Pulsation des Wasserstrahls kann in Weiterbildung der Erfindung vorgesehen sein, daß die Richtung der Drehantriebsstrahlen verändert werden kann. Dies kann beispielsweise durch Änderung der Richtung der Schlitze bewirkt werden.To change the frequency of the pulsation of the water jet may be provided in a further development of the invention that the direction of the rotary drive beams can be changed. This can be effected, for example, by changing the direction of the slots.
Erfindungsgemäß weist die Massagebrause eine Einrichtung zur Erzeugung mindestens eines in seinem Antriebsdrehmoment weniger günstigen Antriebsstrahls auf. Darunter ist ein solcher Strahl zu verstehen, der ein geringeres Antriebsdrehmoment als die übrigen Drehantriebsstrahlen erzeugt, wobei dann zur Änderung der Frequenz der Pulsation dieser weniger günstige Antriebsstrahl anstelle der sonstigen oder eines sonstigen Drehantriebsstrahls eingeschaltet werden kann. Die Erzeugung eines geringeren Drehmoments zur Verringerung der Frequenz wird ohne eine mechanische Reibung erzeugt.According to the invention, the massage shower has a device for generating at least one drive jet which is less favorable in its drive torque. This is to be understood as meaning such a jet which generates a lower driving torque than the other rotary drive beams, in which case this less favorable drive beam can be switched on instead of the other or another rotary drive beam in order to change the frequency of the pulsation. The generation of a lower torque to reduce the frequency is generated without mechanical friction.
Insbesondere kann in Weiterbildung der Erfindung vorgesehen sein, daß der weniger günstige Antriebsstrahl überhaupt kein Antriebselement erzeugt. Er könnte also beispielsweise direkt in radialer Richtung verlaufen.In particular, it can be provided in a development of the invention that the less favorable drive jet generates no drive element at all. So he could, for example, run directly in the radial direction.
In nochmaliger Weiterbildung kann auch vorgesehen sein, daß der weniger günstige Antriebsstrahl ein Drehmoment in umgekehrter Drehrichtung erzeugt. In diesem Fall würde es sich um einen echten Bremsstrahl handeln.In a further development can also be provided that the less favorable drive jet generates a torque in the reverse direction of rotation. In this case it would be a real brake jet.
Erfindungsgemäß kann die Massagebrause eine Einrichtung zum gleichzeitigen Verändern des Strömungsquerschnitts der Drehantriebsstrahlen und der Antriebsstrahlen mit geringerem Drehmoment in umgekehrtem Sinn aufweisen. Dabei kann insbesondere vorgesehen sein, daß die Summe der Querschnitte gleich bleibt. Auch auf diese Weise läßt sich eine Änderung der Frequenz der Pulsationen des Massagestrahls ohne eine mechanische Reibung und ohne Einfluß auf die Menge des austretenden Wassers erreichen.According to the present invention, the massage shower may have means for simultaneously changing the flow area of the rotary driving jets and the lower torque driving jets in the reverse sense. It can be provided in particular that the sum of the cross sections remains the same. In this way, a change in the frequency of the pulsations of the massage jet can be achieved without mechanical friction and without affecting the amount of escaping water.

Fig. 1 zeigt stark vereinfacht schematisch den Brausekopf einer Handbrause. Ein Gehäuse 1 wird von dem Brausekopf abgeschlossen. In dem Gehäuse 1 ist eine Wasserführung 2, die durch den Griff der Brause hindurchgeführt ist und mit einem Zuleitungsschlauch in Verbindung steht. Aus der Wasserführung 2 kann das Wasser durch zwei Durchgänge 3, 4 abwechselnd zu verschiedenen Brauseeinrichtungen gelangen, je nach Stellung eines Umschaltelements. Der Brausekopf wird durch eine Strahlscheibe 5 abgeschlossen, die im dargestellten Beispiel zweiteilig ausgebildet ist, nämlich ein äußeres ringförmiges Strahlscheibenelement und eine innere Strahlscheibe 6, die Strahlaustrittsöffnungen 7 aufweist. Auch der äußere Teil 5 enthält Strahlaustrittsöffnungen 8.Fig. 1 shows greatly simplified schematically the shower head of a hand shower. A housing 1 is closed by the shower head. In the housing 1 is a
Die mittlere Strahlscheibe 6 weist die Form eines ebenen Bodens mit einem zylindrischen Rand 9 auf, die zusammen einen flachzylindrischen Innenraum 10 bilden. Dieser Innenraum 10 ist auf der der Strahlscheibe 6 gegenüberliegenden Seite durch eine flache Platte 11 abgeschlossen. Der zylindrische Rand 9 enthält von außen nach innen durchgehende Öffnungen, in die das Wasser in Richtung des Pfeiles 12 eintreten kann. Innerhalb des durch die Platte 11 und die Strahlscheibe 6 abgeschlossen Raumes ist ein Rotor 13 drehbar angeordnet, der an seiner der Strahlscheibe 6 zugewandten Seite mit einem Verschlußelement 14 versehen ist. Das Verschlußelement 14 verschließt je nach Stellung des Rotors eine oder mehrere der Strahlaustrittsöffnungen 7 oder öffnet diese.The
Wenn das Wasser in den Raum 10 eintritt, so treibt es den Rotor 13 rotierend an und verläßt den Raum 10 durch die gerade geöffneten Strahlaustrittsöffnungen 7. Da diese ständig durch das Verschlußelement 14 verschlossen und wieder geöffnet werden, entsteht am Ausgang jeder Strahlaustrittsöffnung 7 ein pulsierender Wasserstrahl, wobei bei einer konstanten Drehung des Rotors 13 die Frequenz der Pulsationen aller Wasserstrahlen gleich ist, die Wasserstrahlen sich aber zeitlich abwechseln.When the water enters the room 10, it drives the
Fig. 3 zeigt in einem Schnitt durch den Raum 10, wie der Rotor 13 ausgebildet ist und wie er angetrieben wird. Der Rotor 13 enthält eine Nabe 15, von der aus sich acht Flügel 16 schräg gegenüber einem Radius nach außen erstrecken. Die Flügel 16 reichen bis fast an die Innenseite des Randes 9 heran.Fig. 3 shows, in a section through the space 10, how the
An der der Strahlscheibe 6 zugewandten Seite der Flügel 16 ist das Verschlußelement 14 angebracht, beispielsweise als einstückiges Kunststoffteil. Das Verschlußelement 14 erstreckt sich über etwa einen halben Bogen. Es reicht in radialer Richtung von der Außenseite der Flügel 16 bis kurz vor die Nabe 15. Alle Strahlaustrittsöffnungen 7 sind in radialer Hinsicht so angeordnet, daß sie zwischen dem Außenrand und dem Innenrand des Verschlußelements 14 liegen.At the
In dem Rand 9, der in der Figur 2 im Schnitt dargestellt ist, sind insgesamt vier Strahleinlaßöffnungen 17 angeordnet, die schräg verlaufen, und zwar alle in der gleichen Richtung.In the
Unter schräg ist dabei zu verstehen, daß sie gegenüber einem Radius durch den Mittelpunkt des Raumes 10 und damit durch die Drehachse des Rotors 13 schräg verlaufen, beispielsweise unter einem Winkel von 45°. In dem Rand 9 ist zusätzlich ein Schlitz 18 angeordnet, der nicht schräg verläuft, sondern radial. Außerdem weist die Anordnung einem um die Drehachse des Rotors 13 verschiebbaren Schieber 19 auf, der in der Position der Fig. 2 einen der schrägen Schlitze 17 verschließt. In der Position der Fig. 2 tritt das Wasser durch drei schräge Schlitze 17 und einen radialen Schlitz 18 in den Raum 10 ein. Die durch die schrägen Schlitze 17 eintretenden Wasserstrahlen treiben den Rotor 13 im Uhrzeigersinn in Fig. 2 an, während der durch den Schlitz 18 eintretende Wasserstrahl keinen Beitrag zu dem Drehantrieb des Rotors 13 liefert.The term oblique is to be understood as meaning that they run obliquely with respect to a radius through the center of the space 10 and thus through the axis of rotation of the
Wird nun der Schieber 19 aus der in Fig. 2 dargestellten Stellung in die in Fig. 3 dargestellte Stellung verschoben, so verschließt er jetzt den radialen Schlitz 18, während er den bisher verschlossenen schrägen Schlitz 17 öffnet. Nun tritt die Strömung in vier schrägen Wasserstrahlen in den Raum des Rotors 13 ein, während der radiale Wasserstrahl durch den Schlitz 18 abgeschaltet ist. Dies bedeutet, daß jetzt alle Wasserstrahlen einen Beitrag zum Drehantrieb des Rotors 13 liefern. Damit wird der Rotor 13 jetzt schneller angetrieben, so daß sich die Frequenz der Pulsationen der aus den Strahlaustrittsöffnungen 7 austretenden Wasserstrahlen vergrößert.Now, if the
In einer Übergangsstellung, in der der Schieber 19 zwischen den beiden Stellungen der Fig. 2 und 3 angeordnet ist, wird eine mittlere Frequenz hergestellt, da es dann vier Drehantriebsstrahlen und einen sich nicht am Drehantrieb beteiligenden Strahl gibt.In an intermediate position, in which the
Bei dieser durch die Änderungen der Öffnungen bewirkten Veränderung der Frequenz des Massagestrahls tritt keine Änderung der Menge des aus den Strahlaustrittsöffnungen 7 austretenden Wassers und keine vergrößerte Reibung zum Abbremsen des Rotors auf. Außerdem ändert sich die Härte des Strahles nicht, da der Abstand zwischen dem Verschlußelement 14 und den Strahlaustrittsöffnungen 7 gleich bleibt.In this caused by the changes in the openings change in the frequency of the massage jet occurs no change in the amount of water exiting the
