Abstract

The subject of the description is a manual shower which comprises a shower head with separate outlet openings (4, 5) for a constant shower jet on the one hand and pulsating shower jet on the other as well as a change-over device (7, 8, 9), with which device the water can be guided alternately into one of the two groups of outlet openings (4, 5). The aim is to provide a design which is simpler and more operationally reliable than known massage shower types and in which no parts running in bearings, or subject to wear and blockage are required. For this purpose, the outlet openings (5) supplying a pulsating shower jet are combined with an annular circulation channel (15) into which obliquely directed feed channels lead and in which a freely movable float (17) is also located which is set in motion by the obliquely directed water flow from the feed openings and successively blocks a number of the outlet openings (5) in each case. The float (17) has at best a circular cross-section and its main shape is curved to correspond to the curving of the circulation channel (15). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Handbrause mit einem Brausekopf mit Austrittsöffnungen sowohl für einen steten Wasserstrahl als auch für einen pulsierenden Wasserstrahl sowie mit einer Umschaltvorrichtung, mit der das Wasser wahlweise zu einer der beiden Gruppen von Austrittsöffnungen gelenkt werden kann, wobei die für den pulsierenden Wasserstrahl vorgesehenen Austrittsöffnungen mit einem im Brausekopf angeordneten, ringförmigen Umlaufkanal in Verbindung stehen, in dem mindestens ein frei bewegliches, jeweils einen Teil der Austrittsöffnungen sperrendes Schiffchen mit in seinem Querschnitt ausreichendem Spiel angeordnet ist und in den das Wasser über mindestens einen schrägen Einspeisekanal geleitet wird, so daß das Schiffchen durch den Wasserzufluß in den Umlaufkanal in stete Bewegung versetzt wird.The invention relates to a hand shower with a shower head with outlet openings both for a constant water jet and for a pulsating water jet and with a switching device with which the water can be directed either to one of the two groups of outlet openings, the one for the pulsating water jet the intended outlet openings are connected to an annular circulation channel arranged in the shower head, in which at least one freely movable boat, each blocking a part of the outlet openings, is arranged with sufficient play in its cross section, and into which the water is conducted via at least one inclined feed channel, so that the boat is set in constant motion by the inflow of water into the circulation channel.

Eine bekannte Handbrause dieser Art (US-A-4089471) hat einen an seinem Boden Austrittsöffnungen für einen pulsierenden Wasserstrahl aufweisenden Umlaufkanal, der im wesentlichen quadratischen Querschnitt aufweist und in dem sich zum Umlauf bestimmte Kugeln und zum Umlauf bestimmte Körper befinden, die segmentartige Form haben und oben offen sind. In der Deckwand des Umlaufkanals ist ein schräger Einspeisekanal vorhanden, durch den Wasser in den Umlaufkanal gedrückt wird, das die Kugeln und die segmentförmigen Körper in eine Umlaufbewegung versetzen soll, so daß die Austrittsöffnungen zeitweise offen und zeitweise geschlossen sind.A known hand shower of this type (US-A-4089471) has at its bottom outlet openings for a pulsating water jet having a circulation channel which has a substantially square cross-section and in which there are balls intended for circulation and bodies intended for circulation which have a segment-like shape and are open at the top. In the top wall of the circulation channel there is an inclined feed channel through which water is pressed into the circulation channel, which is intended to set the balls and the segment-shaped bodies in a circular motion, so that the outlet openings are temporarily open and temporarily closed.

Diese bekannte Anordnung hat zwei grundsätzliche Nachteile, nämlich einerseits, daß sie Kugeln zum Verschließen der Austrittsöffnungen verwendet, und andererseits, daß sie segmentförmige Körper einsetzt, die oben geöffnet sind. Die verwendeten Kugeln sind beim Umlauf im Umlaufkanal nicht in der Lage, die jeweils benachbarte Austrittsöffnung für eine längere Zeit zu verschließen, so daß es nur zu einer sehr kurzen Unterbrechung des Wasseraustritts und damit nicht zu einer ausgeprägten pulsierenden Strahlbildung kommt. Die segmentförmigen Körper stellen ein Zuverlässigkeitsproblem dar, denn das schräg von oben in sie eintretende Wasser drückt sie gegen die Bodenfläche des Umlaufkanals, so daß es zu einem Verhaken oder Blockieren kommen kann, wobei diese Gefahr noch dadurch vergrößert wird, daß sich die segmentförmigen Körper auch in einer Ebene parallel zur Bodenfläche des Umlaufkanals verkanten können.This known arrangement has two fundamental disadvantages, namely that it uses balls to close the outlet openings and that it uses segment-shaped bodies that are open at the top. The used When circulating in the circulation channel, balls are not able to close the respective adjacent outlet opening for a longer period of time, so that there is only a very short interruption in the water outlet and therefore no pronounced pulsating jet formation. The segment-shaped bodies represent a reliability problem because the water entering them obliquely from above presses them against the bottom surface of the circulation channel, so that they can get caught or jam, which danger is further increased by the fact that the segment-shaped bodies are also can tilt in a plane parallel to the bottom surface of the circulation channel.

Es ist ferner bereits bekannt, Handbrausen für das Umschalten zwischen normalem Duschbetrieb und pulsierendem Duschbetrieb mit einem Flügelrad o.ä. auszustatten, auf das der Wasserstrom gelenkt wird, so daß beim Rotieren des Flügelrades abwechselnd ein Teil der Austrittsöffnungen für das Wasser versperrt wird. Bei dieser bekannten Handbrause stellt jedoch die Lagerung der Flügelradachse ein Problem dar, und darüber hinaus können sich die scharfen Ecken der Flügelnut im Laufe der Zeit abnutzen oder infolge Verschmutzung funktionsuntüchtig werden.It is also already known to use hand showers for switching between normal shower operation and pulsating shower operation with an impeller or the like. equip to which the water flow is directed so that when the impeller rotates, part of the outlet openings are blocked for the water. In this known hand shower, however, the storage of the impeller axis is a problem, and moreover the sharp corners of the wing groove can wear out over time or become inoperative due to contamination.

Es ist Aufgabe der Erfindung, eine Handbrause so zu verbessern, daß bei einfachem Aufbau und zuverlässigem Betrieb ein ausgeprägtes Pulsieren des Wasserstrahls erreicht wird.It is an object of the invention to improve a hand shower so that a pronounced pulsation of the water jet is achieved with a simple structure and reliable operation.

Zur Lösung dieser Aufgabe wird eine Handbrause der eingangs erwähnten Art erfindungsgemäß derart ausgestaltet, daß der Umlaufkanal und das länglich ausgebildete, entsprechend dem Umlaufkanal gekrümmte Schiffchen kreisförmige Querschnitte haben und daß sich die schrägen Einspeisekanäle vom äußeren Umfang in den Umlaufkanal erstrecken.To solve this problem, a hand shower of the type mentioned is designed according to the invention in such a way that the circulation channel and the elongated, curved boat corresponding to the circulation channel have circular cross sections and that the oblique feed channels extend from the outer circumference into the circulation channel.

Durch den kreisförmigen Querschnitt des Umlaufkanals und den kreisförmigen Querschnitt des länglichen Schiffchens, das auf diese Weise einfach herstellbar ist, ergibt sich eine besonders gute Führung im Umlaufkanal, ohne daß die Gefahr des Verkantens besteht, wobei das Schiffchen infolge seiner Form einzelne Austrittsöffnungen für längere Zeit verschließt, so daß sich ein ausgeprägt pulsierender Wasserstrahl ergibt.The circular cross-section of the circulation channel and the circular cross-section of the elongated boat, which is easy to manufacture in this way, result in a special one good guidance in the circulation channel without the risk of canting, the shape of the boat closing individual outlet openings for a long time, so that there is a distinctly pulsating water jet.

Die gleichmäßige Führung und das Vermeiden eines Verkantens des Schiffchens im Umlaufkanal wird auch noch dadurch gefördert, daß das durch die Einspeisekanäle zugeführte Wasser von außen auf das Schiffchen trifft, das infolge seiner Umlaufbewegung im Umlaufkanal durch die Zentrifugalkraft nach außen gedrückt wird. Das zugeführte Wasser wirkt somit der Zentrifugalkraft auf das Schiffchen entgegen und verhindert dadurch, daß dieses am äußeren Umfangsbereich des Umlaufkanals hängen bleibt.The even guidance and the avoidance of canting of the shuttle in the circulation channel is also promoted by the fact that the water supplied through the feed channels hits the shuttle from the outside, which is pressed outwards by the centrifugal force due to its circulation movement in the circulation channel. The water supplied thus counteracts the centrifugal force on the boat and thereby prevents it from getting caught on the outer peripheral region of the circulation channel.

Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further refinements of the invention result from the subclaims.

Die Erfindung wird im folgenden anhand der ein Ausführungsbeispiel darstellenden Figuren näher erläutert. Es zeigen:

  • Fig. 1 die erfindungsgemässe Handbrause im Schnitt seitlich betrachtet,
  • Fig. 2 einen Schnitt längs der Geraden A-A in Fig. 1.
The invention is explained in more detail below with reference to the figures which represent an exemplary embodiment. Show it:
  • 1 shows the hand shower according to the invention viewed laterally in section,
  • FIG. 2 shows a section along the line AA in FIG. 1.

In Fig. 1 ist ein Teil des mit der Bezugszahl 1 bezeichneten Griffes der Handbrause weggelassen. Am Ende des Griffes 1 ist auf normale Weise ein becherförmiger Brausekopf angeordnet, der die pauschale Bezugzahl 2 trägt. An der kreisflächenförmigen Unterseite 3 des Brausekopfes sind zum einen Austrittsöffnungen 4 für stetigen Wasserstrahl und zum anderen Austrittsöffnungen 5 für pulsierenden Wasserstrahl angeordnet.In Fig. 1 part of the handle of the hand shower designated by the reference number 1 is omitted. At the end of the handle 1, a cup-shaped shower head is arranged in a normal manner, which bears the general reference number 2. On the circular underside 3 of the shower head, on the one hand outlet openings 4 for a steady water jet and on the other hand outlet openings 5 for a pulsating water jet are arranged.

Aus fertigungstechnischen Gründen ist zwischen dem becherförmigen Teil 2 und dem unteren Teil 3 des Brausekopfes ein separates Teil 19 angeordnet, und die Teile 3 und 19 sind mit Schrauben 6 am Becherteil 2 befestigt.For manufacturing reasons, a separate part 19 is arranged between the cup-shaped part 2 and the lower part 3 of the shower head, and the parts 3 and 19 are fastened to the cup part 2 with screws 6.

Die Zahl 7 bezeichnet einen zweiarmigen Hebel 7 der Umschaltvorrichtung, der wiederum auf eine in der Zeichnung vertikal bewegliche Spindel 8 wirkt, an deren Ende sich ein Ventilteller 9 befindet.The number 7 denotes a two-armed lever 7 of the switching device, which in turn acts on a spindle 8 which is vertically movable in the drawing, at the end of which there is a valve disk 9.

Die Feder 14 ist bestrebt, den Teller 9 in der in Fig. 1 gezeigten Tiefstellung zu halten, in welcher er gegen die Fläche 10 abdichtet.The spring 14 endeavors to hold the plate 9 in the low position shown in FIG. 1, in which it seals against the surface 10.

Bei Normalstellung, in der sich der Teller 9 gemäss Fig. 1 in Tiefstellung befindet, gelangt das Wasser über den Kanal 11 im Griff 1 in die Kammer 12, welche mit dem ringförmigen Raum 13 im Becherteil 2 in Verbindung steht. Das Wasser tritt in diesem Falle als steter Strom aus den Öffnungen 4 aus.In the normal position, in which the plate 9 is in the low position according to FIG. 1, the water passes through the channel 11 in the handle 1 into the chamber 12, which is connected to the annular space 13 in the cup part 2. In this case, the water emerges from the openings 4 as a constant stream.

Wird der rechte, kürzere Arm des Hebels 7 niedergedrückt, so erfolgt dadurch ein Anheben des Ventiltellers 9, und das Wasser wird in den ringförmigen Kanal 16 gelenkt, von wo es über die Einspeisekanäle 18 in den ringförmigen Umlaufkanal 15 gelangt, wie deutlicher aus Fig. 2 ersichtlich ist, und schliesslich aus den eine pulsierende Dusche liefernden Öffnungen 5 austritt. Dank dem Wasserdruck bleibt der Ventilteller 9 in Hochstellung bis der Wasserzufluss gesperrt oder der längere Arm des Hebels 7 nach unten gezwungen wird.If the right, shorter arm of the lever 7 is depressed, the valve plate 9 is raised and the water is directed into the annular channel 16, from where it reaches the annular circulation channel 15 via the feed channels 18, as is more clearly shown in FIG. 2 can be seen, and finally emerges from the openings 5 providing a pulsating shower. Thanks to the water pressure, the valve plate 9 remains in the high position until the water supply is blocked or the longer arm of the lever 7 is forced downward.

Die Konstruktion des ringförmigen Kanals 16, der Einspeisekanäle 18 und des Umlaufkanals 15 gehen besser aus Fig. 2 hervor. Wie ersichtlich, erstrecken sich die Einspeisekanäle 18 vom ringförmigen Kanal 16 schräg nach innen in den Umlaufkanal 15, wobei die Richtung der Kanäle 18 mit der Tangente des Umlaufkanals 15 einen Winkel von vorzugsweise 30° bis 60° einschliesst. Gemäss der Erfindung ist im Umlaufkanal 15 weiter ein frei bewegliches, mit ausreichendem Spiel in den Kanal 15 passendes Schiffchen 17 angeordnet, dessen Länge so gewählt ist, dass es jeweils einen Teil der Austrittsöffnungen 5 sperrt. Infolge der schrägen Anordnung der Kanäle 18 versetzt der Wasserstrom das Schiffchen 17 in eine stetige Umlaufbewegung.The construction of the annular channel 16, the feed channels 18 and the circulation channel 15 can be better seen in FIG. 2. As can be seen, the feed channels 18 extend obliquely inwards from the annular channel 16 into the circulation channel 15, the direction of the channels 18 including an angle of preferably 30 ° to 60 ° with the tangent of the circulation channel 15. According to the invention, a freely movable shuttle 17, which fits into the channel 15 with sufficient play, is further arranged in the circulation channel 15, the length of which is selected such that it blocks part of the outlet openings 5. As a result of the oblique arrangement of the channels 18, the water flow sets the shuttle 17 in a constant orbital movement.

Beim beschriebenen Ausführungsbeispiel sind die Austrittsöffnungen 5 in drei Gruppen zu je drei Öffnungen angeordnet. Das Schiffchen 17 ist in seiner Länge so bemessen, dass es in einer bestimmten Stellung stets eine Öffnungsgruppe auf einmal abdeckt. Der Positionierung der Austrittsöffnungsgruppen und der Einspeisekanäle kommt im Hinblick auf die Rotationsgeschwindigkeit eine wichtige Bedeutung zu. Die Rotationsgeschwindigkeit ist, so hat man festgestellt, dann am grössten, wenn sich, wie in Fig. 2, die Einspeiseöffnung ungefähr in der Mitte zwischen zwei Öffnungsgruppen befindet. Natürlich ist in der Praxis auch eine Konstruktion mit veränderlichen Mündungsstellen der Einspeisekanäle 18 denkbar. Am leichtesten dürfte dies in der Weise zu bewerkstelligen sein, dass man die Öffnungen 5 an einem separaten, abgedichteten Ringkörper anordnet, dessen Stellung durch Verdrehen geändert werden kann. Auf diese Weise lässt sich die Schwingungsfrequenz der pulsierenden Dusche regulieren.In the described embodiment, the outlet openings 5 are arranged in three groups of three openings each. The length of the boat 17 is such that it always covers one opening group at a time in a certain position. The positioning of the outlet groups and the feed channels are of great importance with regard to the speed of rotation. It has been found that the rotational speed is greatest when, as in FIG. 2, the feed opening is approximately in the middle between two groups of openings. In practice, of course, a construction with variable mouths of the feed channels 18 is also conceivable. The easiest way to do this is to arrange the openings 5 on a separate, sealed ring body, the position of which can be changed by twisting. In this way, the vibration frequency of the pulsating shower can be regulated.
