Description

Die Erfindung betrifft eine Handbrause mit einem Brausekopfteil und einem daran anschließenden Griffteil.The invention relates to a hand shower with a shower head part and an adjoining handle part.

Es ist bekannt, dass es bei solchen Handbrause die Möglichkeit gibt, zwischen verschiedenen Strahlarten umzuschalten. Hierzu wird ein Umschaltventil oder eine sonstige Umschalteinrichtung verwendet, die mithilfe eines Betätigungselements betätigt wird. Dabei hat es sich herausgestellt, dass es sinnvoll ist, das Betätigungselement so anzubringen, dass es der Benutzer mit der Hand betätigen kann, mit der er die Brause am Griff festhält. Dadurch lässt sich ein schnelles Wechseln zwischen unterschiedlichen Strahlarten ermöglichen.It is known that with such a hand shower there is the possibility to switch between different spray types. For this purpose, a switching valve or other switching device is used, which is actuated by means of an actuating element. It has been found that it makes sense to attach the actuator so that it can be operated by the user with which he holds the shower to the handle. This makes it possible to quickly switch between different spray types.

Solche Betätigungselemente können beispielsweise als Druckknöpfe ausgebildet sein, die aus dem Gehäuse der Handbrause herausragen und von dem Benutzer eingedrückt werden. Es kann aber geschehen, dass der Benutzer von dem Griff abrutscht oder ihn nicht findet.Such actuators may be formed, for example, as push buttons that protrude from the housing of the hand shower and pressed by the user. But it can happen that the user slips off the handle or does not find it.

Ebenfalls bekannt ist es, am Ausgang der Handbrause ein die Strahlscheibe umgebendes Ringelement anzuordnen, das zum Umschalten verdrehbar ist, oder aber in einer die Strahlscheibe enthaltenden Ebene radial verschiebbar ausgebildet ist ( DE 198 59 524 A1 ).It is also known to arrange at the outlet of the hand-held showerhead a ring element surrounding the jet disk, which is rotatable for switching over, or is designed to be radially displaceable in a plane containing the jet disk ( DE 198 59 524 A1 ).

Weiterhin ist eine Wasserabgabevorrichtung bekannt, die ein am Ende einer starren Wasserleitung gegenüber dieser Wasserleitung begrenzt verschiebbares Kopfelement mit Strahlaustrittsöffnungen aufweist. Durch die Verschiebung gegenüber der Zuleitung kann ein Umschalten zwischen den Strahlaustrittsöffnungen bewirkt werden ( DE 30 15 180 ).Furthermore, a water dispenser is known which has a limited at the end of a rigid water pipe relative to this water pipe displaceable head element with jet outlet openings. By shifting relative to the supply line, a switching between the jet outlet openings can be effected ( DE 30 15 180 ).

Die Gebrauchsmusterschrift DE 20 2010 005 256 U1 offenbart eine Handbrause, bei der die Strahlscheibe den Bodenbereich einer in einem Brausekopfgehäuse vorgesehenen Kammer mit einem oder mehreren Kammerbereichen bildet und die Kammer samt Strahlscheibe in dem Brausekopfgehäuse als Wippe schwenkbar zur wahlweisen Einstellung einer von mehreren möglichen Strahlformen gelagert ist. Jeder Strahlform entspricht einer spezifische Wippstellung der Strahlscheibe mit ihrer innenseitig anschließenden Kammer relativ zum Brausekopfgehäuse. Somit nimmt bei dieser Handbrause die Strahlscheibe für jede der verschiedenen möglichen Strahlformen eine andere Position ein.The Utility Model DE 20 2010 005 256 U1 discloses a hand shower, wherein the jet disc forms the bottom portion of a chamber provided in a shower head chamber with one or more chamber areas and the chamber is mounted together with jet disk in the shower head housing as a rocker for selectively setting one of several possible beam shapes. Every beam shape corresponds to a specific rocking position of the jet disk with its inside subsequent chamber relative to the showerhead housing. Thus, with this hand shower, the jet disk takes a different position for each of the different possible beam shapes.

In der Gebrauchsmusterschrift DE 7904756 U1 ist eine Handbrause offenbart, bei der die Strahlscheibe elastisch verformbar und mit einem Haltering einstückig ausgebildet ist. Die elastische Verformbarkeit der Strahlscheibe soll dazu dienen, Kalkablagerungen an der Strahlscheibe durch elastisches Verformen der Strahlscheibe von dieser abzusprengen und auf diese Weise zu entfernen.In the utility model DE 7904756 U1 discloses a hand shower, wherein the jet disk is elastically deformable and integrally formed with a retaining ring. The elastic deformability of the jet disk should serve to ablate lime deposits on the jet disk by elastic deformation of the jet disk of this and remove it in this way.

Die Patentschrift US 5,467,927 offenbart eine Handbrause mit einem Brausekopfteil und einem daran anschließenden Griffteil, einer eine Vielzahl von Strahlaustrittsöffnungen aufweisenden, in dem Brausekopfteil angeordneten Strahlscheibe, mindestens einer zu der Strahlscheibe führenden Wasserführung in dem Brausekopfteil, mindestens zwei Strahlaustrittsmöglichkeiten aus der Strahlscheibe und einer Umschalteinrichtung zum Umschalten zwischen den Strahlaustrittsmöglichkeiten, die durch Druck auf die Strahlscheibe betätigbar ist. Konkret wird dort zum Betätigen der Umschalteinrichtung die Strahlscheibe aus einer Ausgangsposition relativ zum Brausekopfgehäuse axial nach hinten bzw. nach innen gedrückt und muss dann in dieser gedrückten Stellung gehalten werden. Sobald die Strahlscheibe losgelassen wird, kehrt sie in ihre Ausgangsposition zurück, und dadurch wird auch die Umschalteinrichtung erneut in einem rückkehrenden Umschaltsinn betätigt.The patent US 5,467,927 discloses a hand shower with a shower head part and an adjoining handle part, a plurality of jet outlet openings, arranged in the shower head part jet disc, at least one leading to the jet washer water guide in the shower head part, at least two Strahlaustrittsmöglichkeiten from the jet disk and a switching device for switching between the beam exit options , which is actuated by pressure on the jet disk. Specifically, there is pressed to actuate the switching device, the jet disk from a starting position relative to the showerhead housing axially to the rear or inward and must then be held in this depressed position. As soon as the jet disk is released, it returns to its starting position, and thereby the switching device is also actuated again in a return switching direction.

Die Offenlegungsschrift DE 2 235 217 offenbart eine Duschanlage mit einer regulierbar konkav oder konvex durchbiegbaren Strahlscheibe und einer zugehörigen Verstelleinrichtung zum Verstellen der Durchbiegung der Strahlscheibe.The publication DE 2 235 217 discloses a shower system with a controllably concave or convex deflectable jet disk and an associated adjusting device for adjusting the deflection of the jet disk.

Der Erfindung liegt die Aufgabe zu Grunde, die Benutzungsmöglichkeiten einer Handbrause im Hinblick auf ein leichtes und fehlerfreies Bedienen zu verbessern.The invention is based on the object to improve the possibilities of using a hand shower with a view to easy and error-free operation.

Zur Lösung dieser Aufgabe schlägt die Erfindung eine Handbrause mit den im Anspruch 1 genannten Merkmalen vor. Weiterbildungen der Erfindung sind Gegenstand von Unteransprüchen. Erfindungsgemäß fungiert die Strahlscheibe der Handbrause als ein Druckbetätigungselement zum Umschalten zwischen den verschiedenen Strahlaustrittsmöglichkeiten.To solve this problem, the invention proposes a hand shower with the features mentioned in claim 1. Further developments of the invention are the subject of dependent claims. According to the invention, the jet disk of the hand shower functions as a pressure actuating element for switching between the different jet outlet possibilities.

Die üblicherweise seitlich an dem Brausekopfteil der Handbrause angebrachte, die Strahlaustrittsöffnungen aufweisende Strahlscheibe hat eine gegenüber einem einzelnen Betätigungsknopf große Fläche, so dass der Benutzer sie auf jeden Fall findet, ohne hinzusehen. Wenn er die Umschaltung bei laufender Brause durchführt, kann er dies auch fühlen. Die Strahlscheibe reicht auch üblicherweise bis an den Griff heran, so dass man sie bei normaler Griffhaltung mit dem Daumen betätigen kann.The jet disk, which is usually attached laterally to the shower head part of the hand shower and has the jet outlet openings, has a large area compared to a single actuating button so that the user can find it without looking. If he performs the switching while the shower is running, he can feel this too. The jet disk usually reaches up to the handle, so that you can operate it with a normal grip position with your thumb.

Gemäß einem Aspekt der Erfindung nimmt die Strahlscheibe nach dem jeweiligen Umschaltvorgang wieder ihre Ausgangsposition vor dem Umschaltvorgang ein. Gemäß einem weiteren Aspekt der Erfindung weist die Umschalteinrichtung ein im Brausekopfteil beweglich angeordnetes Ventilelement auf, das zum Umschalten zwischen verschiedenen, den Strahlaustrittsmöglichkeiten entsprechenden Ventilstellungen durch die Druckbetätigung der Strahlscheibe eingerichtet ist.According to one aspect of the invention, the jet disk resumes its initial position before the switching operation after the respective switching operation. According to a further aspect of the invention, the switching device has a valve element movably arranged in the shower head part, which is set up for switching between different valve positions corresponding to the jet outlet possibilities by the pressure actuation of the jet disk.

Durch die Erfindung wird eine verbesserte und erleichterte Benutzung einer Handbrause mit Umschaltmöglichkeit erreicht. Zusätzlich kann sich auch die Herstellung und die Wartung der Handbrause vereinfachen, da kein zusätzliches Betätigungselement angebracht werden muss. Auch Reinigungsprobleme an der Stelle, an der ein Betätigungselement durch das Gehäuse der Handbrause hindurchgreift, werden vermieden.By the invention, an improved and easier use of a hand shower with switching option is achieved. In addition, the manufacture and maintenance of the hand shower can be simplified because no additional actuator must be attached. Cleaning problems at the point at which an actuating element passes through the housing of the hand shower, are avoided.

Die verschiedenen Strahlaustrittsmöglichkeiten, zwischen denen mithilfe der Umschalteinrichtung umgeschaltet werden soll, können beispielsweise unterschiedliche Strahlarten sein, die aus unterschiedlichen Strahlöffnungen oder auch aus den gleichen Strahlaustrittsöffnungen austreten. Es kann sich auch um identische Strahlarten handeln, die aus verschiedenen Strahlaustrittsöffnungen oder auch in unterschiedliche Richtungen austreten. Selbstverständlich sind auch Kombinationen aller dieser Möglichkeiten von der Erfindung abgedeckt.The different beam exit possibilities, between which the switchover device is to be used, may, for example, be different jet types which emerge from different jet openings or also from the same jet outlet openings. It can also be identical jet types that emerge from different jet outlet openings or in different directions. Of course, combinations of all these possibilities are covered by the invention.

Eine Möglichkeit, wie man durch Druck auf die Strahlscheibe die Umschalteinrichtung betätigen kann, ist dadurch gegeben, dass die Strahlscheibe verschiebbar gegenüber dem Brausekopfteil gelagert ist. Diese Verschiebung wird dann direkt auf die Umschalteinrichtung übertragen.One way in which one can actuate the switching device by pressure on the jet disk, is given by the fact that the jet disk is slidably mounted relative to the shower head part. This shift is then transmitted directly to the switching device.

Eine weitere Möglichkeit, die von der Erfindung vorgeschlagen wird, besteht darin, die Strahlscheibe verkippbar gegenüber dem Brausekopfteil der Handbrause zu lagern. Dabei wird vorzugsweise eine Kippachse verwendet, die quer zur Längsrichtung des Griffs verläuft.Another possibility, which is proposed by the invention, is to store the jet disc tiltable relative to the shower head part of the hand shower. In this case, a tilting axis is preferably used, which extends transversely to the longitudinal direction of the handle.

Eine nochmals weitere Möglichkeit, durch Druck auf die Strahlscheibe eine Umschaltung vorzunehmen, kann darin bestehen, dass die Strahlscheibe verformbar ausgebildet ist, beispielsweise in dem Bereich der Strahlscheibe, der an den Griff angrenzt.Yet another possibility to make a switch by pressure on the jet disk, may consist in that the jet disk is formed deformable, for example in the region of the jet disk, which is adjacent to the handle.

In allen Fällen ist die Anordnung so getroffen, dass die Strahlscheibe nur während des Umschaltens ihre Position bzw. Form ändert und anschließend sofort wieder in ihre Ausgangsposition zurückkehrt. Dies kann insbesondere dann von Vorteil sein, wenn die Strahlscheibe verkippt wird, da dann vermieden wird, dass sich die Richtung der Strahlen gegenüber einer normalen Richtung ändert.In all cases, the arrangement is such that the jet disc changes its position or shape only during the switching and then immediately returns to its original position. This can be particularly advantageous when the jet disk is tilted, since it is then avoided that the direction of the beams changes with respect to a normal direction.

In weiterer Ausgestaltung der Erfindung kann vorgesehen sein, dass die Umschalteinrichtung als Fortschalteinrichtung ausgebildet ist, was insbesondere dann besonders sinnvoll ist, wenn die Handbrause mehr als zwei Strahlaustrittsmöglichkeiten aufweist.In a further embodiment of the invention can be provided that the switching device is designed as a switching device, which is particularly useful especially when the hand shower has more than two beam exit options.

Erfindungsgemäß kann vorgesehen sein, dass die Umschalteinrichtung etwa in der Mitte des Brausekopfteils angeordnet ist. Diese Lösung ist dann vorzuzehen, wenn die Strahlscheibe verschoben wird.According to the invention it can be provided that the switching device is arranged approximately in the middle of the shower head part. This solution is to be anticipated when the jet disk is displaced.

In Weiterbildung der Erfindung kann vorgesehen sein, dass die Umschalteinrichtung gegenüber einer Mitte des Brausekopfs in Richtung auf den Handgriff versetzt ausgebildet ist. Diese Möglichkeit ist insbesondere dann von Vorteil, wenn die Umschalteinrichtung durch Verkippen der Strahlscheibe betätigt wird und der Benutzer am Rand der Strahlscheibe angreift. Dann steht auch bei einem nur geringfügigen Verkippen ein ausreichender Betätigungsweg für die Umschalteinrichtung zur Verfügung.In a further development of the invention can be provided that the switching device is formed offset from a center of the shower head in the direction of the handle. This option is particularly advantageous if the switching device is actuated by tilting the jet disk and the user attacks at the edge of the jet disk. Then there is a sufficient actuation path for the switching device even with a slight tilting.

Die Umschalteinrichtung kann bevorzugt ein Ventil beinhalten, bei dem es sich um ein beliebiges bekanntes Ventil üblicher Bauweise handeln kann. Insbesondere kann vorgesehen sein, dass die Umschalteinrichtung zwischen den verschiedenen Strahlaustrittsmöglichkeiten ein Plattenventil mit einem verdrehbaren Ventilelement aufweist. Das Plattenventil kann dazu einen Zwischenboden mit vom Ventilelement selektiv verschließbaren Bohrungen und einen im Zwischenboden axialbeweglich geführten Betätigungsstift aufweisen.The switching device may preferably include a valve, which may be any known valve of conventional construction. In particular, it can be provided that the switching device has a plate valve with a rotatable valve element between the different jet outlet possibilities. To this end, the plate valve can have an intermediate bottom with bores which can be selectively closed by the valve element and an actuating pin guided axially movably in the intermediate bottom.

In der Handbrause gibt es ein Umschaltventil, mit dessen Hilfe die Wasserströmung entweder zu den konzentrischen Ringen von Strahlaustrittsöffnungen 4 oder zu den drei mittleren Strahlöffnungen 5 geleitet werden kann.In FIG. 1 is a hand shower aborted shown. The hand shower contains a shower head part 1 with a jet disk 2 and an attached thereto handle 3, which is shown only broken off. In the flat jet disk 2 3 concentric circles of jet outlet openings 4 are formed, and in the middle within the first ring of the jet outlet openings 4, three larger jet openings 5 are present. In the hand shower, there is a switching valve, with the aid of which the water flow can be directed either to the concentric rings of jet outlet openings 4 or to the three central jet openings 5.

Die Figur 2 zeigt einen Längsschnitt durch den Brausekopfteil 1 und den Griff 2. Durch den Griff 2 führt ein Kanal 6 zu einem Hohlraum 7 in dem Brausekopfteil 1. Von diesem Hohlraum gelangt das Wasser je nach Stellung eines darin enthaltenen Ventils über jeweils einer Wasserführung zu der Strahlscheibe. Die Strahlscheibe 2 ist eben ausgebildet und enthält parallel zu ihr und mit ihr verbunden eine Trennscheibe 8. Die Wasserführung aus dem Raum 7 führt in den Raum zwischen der Trennscheibe 8 und der Strahlscheibe 2.The FIG. 2 shows a longitudinal section through the shower head part 1 and the handle 2. Through the handle 2, a channel 6 leads to a cavity 7 in the shower head part 1. From this cavity, the water passes depending on the position of a valve contained therein in each case a water supply to the jet disk. The jet disk 2 is flat and contains parallel to it and connected to it a cutting disc 8. The water supply from the room 7 leads into the space between the cutting disk 8 and the jet disk. 2

Die Umschalteinrichtung enthält einen Zwischenboden 9, der von zwei Bohrungen 10, 11 durchquert wird. An der der Strahlscheibe 2 zugewandten Seite schließen sich an die Bohrungen 10, 11 jeweils ein Faltenschlauch 12 an, der mit der Trennscheibe 8 verbunden ist und dort durch Durchtrittsöffnungen in den Zwischenraum zwischen der Strahlscheibe 2 und der Trennscheibe 8 führt.The switching device includes an intermediate bottom 9, which is traversed by two holes 10, 11. On the side facing the jet disk 2, in each case, a corrugated hose 12 adjoins the bores 10, 11, which is connected to the cutting disk 8 and leads there through passage openings into the intermediate space between the jet disk 2 and the separating disk 8.

Auf der von der Strahlscheibe 2 abgewandten Eingangsseite des Zwischenbodens 9 liegt das Ventilelement 13 des Plattenventils auf. Das Ventilelement 13 weist etwa die Form einer halbkreisförmigen Scheibe auf. Die Form kann man der Figur 4 entnehmen.On the side facing away from the jet disk 2 input side of the intermediate bottom 9, the valve element 13 of the plate valve is located. The valve element 13 has approximately the shape of a semicircular disc. The shape you can the FIG. 4 remove.

Auf der nach innen gerichteten eingangsseitigen Seite der Trennscheibe 8 stützt sich ein in dem Zwischenboden 9 geführter Stift 14 ab, der mit einer Einrichtung zum Verdrehen des Ventilelements 13 verbunden ist. Das Ventilelement 13 wird durch eine Druckfeder 15 auf die Eingangsseite des Zwischenbodens 9 angedrückt.On the inwardly directed input side of the blade 8 is guided in the intermediate bottom 9 guided pin 14, which is connected to a device for rotating the valve element 13. The valve element 13 is pressed by a compression spring 15 on the input side of the intermediate bottom 9.

In der in den Figuren 1 bis 4 dargestellten Position ist die eine Bohrung 11 des Zwischenbodens 9 durch das Ventilelement 13 geschlossen. Das Wasser kann aus dem Raum 7 nur durch die andere Bohrung 10 und damit in einem bestimmten Bereich zwischen der Trennscheibe 8 und der Strahlscheibe 2 gelangen.In the in the FIGS. 1 to 4 shown position, the one hole 11 of the intermediate bottom 9 is closed by the valve element 13. The water can pass from the space 7 only through the other hole 10 and thus in a certain area between the cutting disc 8 and the jet disk 2.

Um die Umschalteinrichtung zu betätigen, drückt der Benutzer in Richtung des Pfeils 16 in Figur 5 auf den Bereich der Strahlscheibe 2, der dem Griff 3 benachbart ist. Dadurch verkippt die Strahlscheibe 2 in der in Figur 5 dargestellten Weise. Durch das Verkippen der Strahlscheibe, siehe Figur 6, wird der Stift 14 nach oben verschoben, so dass das Ventilelement 13 von dem Zwischenboden 9 abhebt. Gleichzeitig wird aufgrund von vorhandenen Schrägflächen das Ventilelement 13 verdreht. Im Augenblick des Umschaltens, siehe Figur 7, sind beide Bohrungen 10, 11 geöffnet.To actuate the switching device, the user presses in the direction of arrow 16 in FIG. 5 on the area of the jet disk 2, which is adjacent to the handle 3. This tilts the jet disk 2 in the in FIG. 5 shown way. By tilting the jet disk, see FIG. 6 , the pin 14 is displaced upward, so that the valve element 13 lifts off from the intermediate bottom 9. At the same time, the valve member 13 is rotated due to existing inclined surfaces. At the moment of switching, see FIG. 7 , both holes 10, 11 are open.

Anschließend lässt der Benutzer die Strahlscheibe 2 wieder los. Die Feder 15 drückt das Ventilelement 13 in Richtung auf den Zwischenboden. Gleichzeitig drückt die Feder 15 den Stift 14 gegen die Trennscheibe 8, so dass jetzt die Strahlscheibe wieder in ihre Ausgangsposition gedrückt wird. Bei der Abwärtsbewegung von Stift 14 und Ventilelement 13 erfolgt wegen der dort vorhandenen Schrägflächen eine weitere Verdrehung des Ventilelements 13.Then the user lets go of the jet disk 2 again. The spring 15 presses the valve element 13 in the direction of the intermediate bottom. At the same time, the spring 15 presses the pin 14 against the cutting disk 8, so that now the jet disk is pressed back into its starting position. During the downward movement of the pin 14 and valve element 13, a further rotation of the valve element 13 takes place because of the oblique surfaces present there.

Am Ende der Rückwärtsbewegung nimmt die Strahlscheibe 2 wieder die in Figur 9 dargestellte Position ein, die der Position der Figur 1 entspricht.At the end of the backward movement, the jet disk 2 again takes in FIG. 9 shown position, the position of the FIG. 1 equivalent.

Die Position des Ventilelements 13 hat sich jedoch geändert, was man der Figur 10 und insbesondere der Ausschnittvergrößerung der Figur 11 entnehmen kann. Während ursprünglich das Ventilelement 13 die linke Bohrung 11 verschließt, ist jetzt die linke Bohrung 11 geöffnet und die rechte Bohrung 10 durch das Ventilelement 13 geschlossen. Dadurch fließt das Wasser aus der Kammer 7 durch die Bohrung 11, den zugehörigen Schlauch 12 und eine Öffnung der Trennscheibe 8 in den anderen Raum zwischen Trennscheibe und Strahlscheibe. Diese beiden Räume sind durch einen Steg 17 voneinander getrennt.However, the position of the valve element 13 has changed, which is the FIG. 10 and in particular the cutting magnification of the FIG. 11 can take. While originally the valve element 13 closes the left bore 11, the left bore 11 is now open and the right bore 10 is closed by the valve element 13. As a result, the water flows from the chamber 7 through the bore 11, the associated tube 12 and an opening of the cutting disc 8 in the other space between blade and jet disk. These two spaces are separated by a web 17.

Die Figur 12 zeigt jetzt, dass das Ventilelement 13 eine um 180° verdrehte Position einnimmt.The FIG. 12 now shows that the valve element 13 assumes a 180 ° rotated position.

In der dargestellten Ausführungsform enthält die Handbrause einen Griff und einen Kopfteil mit einer Strahlscheibe. Die Strahlscheibe weist zwei Arten von Strahlaustrittsöffnungen auf. In dem Kopfteil der Handbrause ist eine Umschalteinrichtung vorgesehen, mit der das Wasser entweder zu der einen Art von Strahlaustrittsöffnungen oder zu der anderen Art geleitet werden kann. Zum Betätigen der Umschalteinrichtung dient die Strahlscheibe selbst, die verkippt werden kann und dadurch die Umschalteinrichtung betätigt. Zum Angreifen an der Strahlscheibe ist eine Stelle in der Nähe des Handgriffs vorgesehen. Diese Stelle kann auch eine muldenartige Vertiefung aufweisen oder von ihr gebildet werden.In the illustrated embodiment, the hand shower includes a handle and a head portion with a jet disk. The jet disk has two types of jet outlet openings. In the head part of the hand shower, a switching device is provided, with which the water can be directed either to the one type of jet outlet openings or to the other type. To actuate the switching device is the jet disk itself, which can be tilted and thereby actuates the switching device. To engage the jet disk, a location near the handle is provided. This site may also have a trough-like depression or be formed by it.
