Description

Die Erfindung bezieht sich auf eine Brause, beispielsweise eine Handbrause oder eine Kopfbrause, mit einem Brausekopfgehäuse, das eine Strahlscheibe mit mehreren Gruppen von Strahlaustrittsöffnungen aufweist.The invention relates to a shower head, for example a hand shower or an overhead shower, with a shower head housing which has a jet disk with several groups of jet outlet openings.

Es sind bereits Brausen bekannt, die in ihrer Strahlscheibe eine Vielzahl von Strahlaustrittsöffnungen aufweisen, aus denen beispielsweise zwei unterschiedliche Strahlen abgegeben werden können, wie harte oder weiche Strahlen. Zwischen beiden Strahlarten kann durch einen manuell zu betätigenden Umschalter umgeschaltet werden.Showers are already known which have a large number of jet outlet openings in their jet disc, from which, for example, two different jets can be emitted, such as hard or soft jets. A manually operated switch can be used to switch between the two jet types.

Die Strahlaustrittsöffnungen sind beispielsweise in konzentrischen Ringen angeordnet, wobei die unterschiedlichen Strahlarten derart zusammengefasst sind, dass ein Ring die eine Art von Strahlen und der nächste Ring die andere Art von Strahlen abgibt. Um dies zu erreichen, sind ringförmige Kammern hinter der Strahlscheibe angeordnet, die jeweils bis zu der Rückseite der Strahlscheibe reichen. Es handelt sich also um eine Anordnung der Kammern nebeneinander.The jet outlet openings are arranged, for example, in concentric rings, the different jet types being combined in such a way that one ring emits one type of jets and the next ring emits the other type of jets. In order to achieve this, annular chambers are arranged behind the jet disk, each of which extends to the rear of the jet disk. It is therefore an arrangement of the chambers next to one another.

Bei einem in der Offenlegungsschrift GB 2 270 859 A offenbarten Brausekopf dieser Art weist die Strahlscheibe drei konzentrische kreisförmige Ringe von Strahlaustrittsöffnungen auf. Ein mittlerer Ring gibt belüftete Strahlen ab, ein innerer Ring gibt Massagestrahlen ab, und ein äußerer Ring gibt einen konischen Strahl ab.With one in the Offenlegungsschrift GB 2 270 859 A disclosed shower head of this type, the spray disc has three concentric circular rings of spray outlets. A middle ring emits aerated jets, an inner ring emits massage jets, and an outer ring emits a conical jet.

Für eine solche Anordnung von Brausestrahlen in herkömmlichen Brausen ergibt sich beim Umschalten zwischen den verschiedenen Strahlarten auch eine Änderung des Strahlbilds, da in den verschiedenen Fällen die Strahlen über unterschiedliche Bereiche der Strahlscheibe abgegeben werden. Die verschiedenen zugehörigen Gruppen von Strahlaustrittsöffnungen werden über zugeordnete vorgelagerte Kammern mit Wasser versorgt, die voneinander getrennt nebeneinander im Inneren eines Gehäuses der Brause angeordnet sind und wahlweise mit einem Wassereinlass in Fluidverbindung gebracht werden können.For such an arrangement of shower jets in conventional showers, there is also a change in the jet pattern when switching between the different jet types, since in the different cases the jets are emitted over different areas of the jet disk. The various associated groups of jet outlet openings are supplied with water via associated upstream chambers which are arranged separately from one another in the interior of a housing of the shower and can optionally be brought into fluid connection with a water inlet.

In der Gebrauchsmusterschrift DE 20 2009 015 042 U1 ist ein Brausekopf ähnlicher Art offenbart, bei dem eine erste Bewässerungskammer mit einem zugehörigen Satz von ersten Wasserauslässen durch eine ringförmige Trennwand von einer zweiten Bewässerungskammer mit einem zugehörigen Satz von zweiten Wasserauslässen getrennt ist. Den beiden an eine Strahlaustrittsscheibe mit den Wasserauslässen angrenzenden Bewässerungskammern ist ein Wasseraufteilungselement vorgeschaltet, das zwei Wasseraufteilungsöffnungen aufweist, von denen umschaltbar jeweils die eine geöffnet und die andere geschlossen werden kann, um Wasser, das über einen Einlasskanal in eine Vorkammer vor den Wasseraufteilungsöffnungen zugeführt wird, umschaltbar der ersten oder der zweiten Bewässerungskammer zuzuführen.In the utility model DE 20 2009 015 042 U1 a shower head of a similar type is disclosed in which a first irrigation chamber with an associated set of first water outlets is separated by an annular partition wall from a second irrigation chamber with an associated set of second water outlets. The two irrigation chambers adjoining a jet outlet disc with the water outlets are preceded by a water dividing element which has two water dividing openings, one of which can be switched to open and the other to be closed, in order to dispense water that is supplied via an inlet channel into an antechamber in front of the water dividing openings. switchable to supply the first or the second irrigation chamber.

In der Offenlegungsschrift US 2009/0289129 A1 ist ein weiterer Brausekopf ähnlicher Art mit einer mittigen Gruppe von Strahlaustrittsöffnungen und einer peripheren Gruppe von Strahlaustrittsöffnungen offenbart, wobei in einer ersten Betriebsart über die peripheren Öffnungen ein kontinuierlicher Wasserstrahl abgegeben werden kann, während in einer zweiten Betriebsart ein Massagestrahl über die mittleren Öffnungen abgegeben wird und in einer dritten Strahlart ein kombinierter Strahl aus beiden Gruppen von Strahlaustrittsöffnungen abgegeben wird.In the Offenlegungsschrift US 2009/0289129 A1 Another shower head of a similar type with a central group of jet outlets and a peripheral group of jet outlets is disclosed, wherein in a first operating mode a continuous water jet can be emitted via the peripheral openings, while in a second operating mode a massage jet is emitted via the central openings and In a third jet type, a combined jet from both groups of jet outlet openings is emitted.

Der Erfindung liegt die Aufgabe zu Grunde, eine Brause der eingangs genannten Art zu schaffen, bei der die Austrittstrahlen möglichst gleichmäßig über die gesamte Austrittsfläche der Strahlscheibe verteilt sein können, so dass bei einer Umschaltmöglichkeit zwischen unterschiedlichen Strahlen das Gesamtbild möglichst wenig geändert wird, und sich das Brausekopfgehäuse mit relativ wenig Aufwand herstellen lässt.The invention is based on the object of creating a shower of the type mentioned, in which the exit jets can be distributed as evenly as possible over the entire exit surface of the jet disc, so that the overall image is changed as little as possible when switching between different jets the shower head housing can be produced with relatively little effort.

Zur Lösung dieser Aufgabe schlägt die Erfindung eine Brause mit den im Anspruch 1 genannten Merkmalen vor. Weiterbildungen der Erfindung sind Gegenstand von Unteransprüchen. Bei der Brause kann es sich um eine Handbrause, eine Kopfbrause oder auch um eine Seitenbrause handeln.To solve this problem, the invention proposes a shower head with the features mentioned in claim 1. Further developments of the invention are the subject of subclaims. The shower head can be a hand shower, an overhead shower or a side shower.

Das Brausekopfgehäuse enthält also mindestens zwei Kammern, die für die Wasserversorgung der Strahlaustrittsöffnungen zuständig sind. Mindestens eine dieser beiden Kammern ist für die Wasserversorgung ausschließlich einer Gruppe von Strahlaustrittsöffnungen in der Strahlscheibe zuständig.The shower head housing therefore contains at least two chambers that are responsible for the water supply to the jet outlet openings. At least one of these two chambers is responsible for the water supply exclusively to a group of jet outlets in the jet disc.

Die Anordnung der beiden Kammern hintereinander hat den Vorteil, dass der Aufwand für die Erstellung des Brausekopfgehäuses niedrig ist und es dadurch relativ einfach möglich ist, die zugehörigen Austrittsstrahlen gleichmäßig über die Austrittsfläche der Strahlscheibe zu verteilen.The arrangement of the two chambers one behind the other has the advantage that the effort for creating the shower head housing is low and it is therefore relatively easy to distribute the associated outlet jets evenly over the outlet surface of the jet disc.

Zur Ermöglichung eines einfachen Aufbaus ist erfindungsgemäß vorgesehen, dass die Strahlaustrittsöffnungen durch Nippel aus elastomerem Material gebildet sind, die an einer gemeinsamen an der Innenseite der Strahlscheibe anliegenden Platte aus diesem Material angeformt sind. Vorzugsweise treten die Nippel aus der Strahlscheibe auf der Vorderseite um einen gewissen Abstand aus.To enable a simple structure, it is provided according to the invention that the jet outlet openings are formed by nipples made of elastomeric material, which are molded onto a common plate made of this material that rests on the inside of the jet disc. The nipples preferably emerge from the jet disc at the front by a certain distance.

Wenn nur eine dieser Kammern für die Wasserversorgung ausschließlich einer Gruppe von Strahlaustrittsöffnungen zuständig ist, so kann die andere Kammer beide Gruppen von Strahlaustrittsöffnungen mit Wasser versorgen.If only one of these chambers is responsible for the water supply exclusively to a group of jet outlet openings, the other chamber can supply both groups of jet outlet openings with water.

Gemäß einem Aspekt der Erfindung stehen die Strahlaustrittsöffnungen einer Gruppe von Strahlaustrittsöffnungen durch Kanäle mit einer hinteren der Kammern in Verbindung, die durch eine vordere der Kammern hindurch gehen. Das Wasser tritt also aus der hinteren Kammer durch für jede Strahlaustrittsöffnung einen eigenen Kanal aus der Brause aus. Dabei greifen an einer Trennwand zwischen beiden Kammern angeformte Stutzen in die an ihrer Innenseite optional verlängerten Nippel ein, wobei diese Stutzen die Kanäle bilden, durch die das Wasser aus der hinteren Kammer zu den Strahlaustrittsöffnungen der Strahlscheibe gelangt.According to one aspect of the invention, the jet outlet openings of a group of jet outlet openings are connected through channels to a rear one of the chambers which pass through a front one of the chambers. The water comes out of the rear chamber through a separate channel for each jet outlet opening Shower out. In this case, nozzles formed on a partition between the two chambers engage in the nipples, which are optionally lengthened on their inside, whereby these nozzles form the channels through which the water from the rear chamber reaches the jet outlet openings of the jet disc.

Gemäß einem weiteren Aspekt der Erfindung weist eine hintere der Kammern eigene Strahlaustrittsöffnungen auf, die gegenüber Strahlaustrittsöffnungen der Strahlscheibe konzentrisch ausgerichtet sind und einen kleineren Durchmesser aufweisen. Das aus der hinteren Kammer austretende Wasser tritt also als einzelne Strahlen aus, die eine vordere der Kammern durchqueren und nur durch jeweils diejenigen Strahlaustrittsöffnungen austreten, die der hinteren Kammer zugeordnet sind. Dazu sind die eigenen Strahlaustrittsöffnungen der hinteren Kammer von Stutzen gebildet, die an einer Trennwand zwischen der vorderen und der hinteren Kammer angeformt sind.According to a further aspect of the invention, a rear one of the chambers has its own jet outlet openings which are aligned concentrically with respect to jet outlet openings of the jet disc and have a smaller diameter. The water emerging from the rear chamber thus emerges as individual jets which traverse a front of the chambers and only emerge through those jet outlet openings which are assigned to the rear chamber. For this purpose, the rear chamber's own jet outlet openings are formed by nozzles which are molded onto a partition between the front and rear chambers.

In Weiterbildung der Erfindung kann vorgesehen sein, dass beide Kammern ausschließlich für die Wasserversorgung jeweils einer Gruppe von Strahlaustrittsöffnungen zuständig sind.In a further development of the invention, it can be provided that both chambers are exclusively responsible for the water supply to one group of jet outlet openings.

Bei der Anordnung zweier Wasserversorgungskammern hintereinander ist es sinnvoll und wird von der Erfindung vorgeschlagen, dass eine Kammer direkt hinter der Strahlscheibe angeordnet ist, so dass eine Gruppe von Strahlaustrittsöffnungen direkt in diese hinter der Strahlscheibe angeordnete und damit als vordere Kammer zu bezeichnende Kammer führt.When arranging two water supply chambers one behind the other, it makes sense and is proposed by the invention that one chamber is arranged directly behind the jet disk so that a group of jet outlet openings leads directly into this chamber, which is arranged behind the jet disk and is thus designated as the front chamber.

Sinnvollerweise ist zur Ermöglichung eines einfachen Aufbaus die hintere Kammer direkt hinter der vorderen Kammer angeordnet, also von dieser nur durch eine Trennwand getrennt.It is sensible to arrange the rear chamber directly behind the front chamber, that is to say only separated from it by a partition, in order to enable a simple structure.

Erfindungsgemäß kann in Weiterbildung die Brause ein manuell betätigbares Umschaltventil aufweisen, um jeweils eine der beiden Kammern mit dem Wassereinlass in das Brausekopfgehäuse in Verbindung zu bringen. Hiermit kann also zwischen den unterschiedlichen Wasserstrahlen umgeschaltet werden, was besonders sinnvoll ist, wenn es sich um unterschiedliche Arten von Wasserstrahlen handelt.According to the invention, in a further development, the shower head can have a manually operable switchover valve in order to bring one of the two chambers into connection with the water inlet in the shower head housing. This allows you to choose between the different water jets be switched, which is particularly useful when it comes to different types of water jets.

Es ist aber ebenfalls möglich, das Umschaltventil so auszugestalten, dass es auch die Möglichkeit der Wasserversorgung beider Kammern gleichzeitig umfasst. Eine solche Möglichkeit ist auch dann sinnvoll, wenn die beiden Gruppen von Strahlaustrittsöffnungen die gleiche Art von Wasserstrahlen abgeben. Man kann auf diese Weise die Menge des abzugebenden Wassers in gewissem Ausmaß regulieren.However, it is also possible to design the switch valve in such a way that it also includes the possibility of supplying water to both chambers at the same time. Such a possibility is also useful if the two groups of jet outlet openings emit the same type of water jets. In this way, the amount of water to be dispensed can be regulated to a certain extent.

Erfindungsgemäß kann vorgesehen sein, dass die Strahlaustrittsöffnungen beider Gruppen von Strahlaustrittsöffnungen in der Strahlscheibe gemischt bzw. gleichmäßig verteilt angeordnet sind.According to the invention it can be provided that the jet outlet openings of both groups of jet outlet openings are arranged in the jet disk in a mixed manner or evenly distributed.

Erfindungsgemäß kann vorgesehen sein, dass die Strahlaustrittsöffnungen beider Gruppen von Strahlaustrittsöffnungen identisch sind, insbesondere dann, wenn mit dem Umschaltventil zwischen der Versorgung einer Gruppe einerseits und der Versorgung beider Gruppen gleichzeitig umgeschaltet werden soll. Dann kann die Versorgung nur einer Gruppe von Strahlaustrittsöffnungen als Sparschaltung betrachtet werden.According to the invention it can be provided that the jet outlet openings of both groups of jet outlet openings are identical, in particular if the switching valve is to be used to switch between the supply of one group on the one hand and the supply of both groups at the same time. Then the supply of only one group of jet outlets can be viewed as an economy circuit.

Eine weitere Möglichkeit besteht darin, dass die Strahlaustrittsöffnungen beider Gruppen zur Abgabe unterschiedlicher Strahlarten ausgebildet sind.Another possibility is that the jet outlet openings of both groups are designed to deliver different jet types.

Es kann erfindungsgemäß vorgesehen sein, dass die Strahlaustrittsöffnungen einer Gruppe untereinander identisch sind bzw. die gleiche Art von Strahlen ausgeben.According to the invention, it can be provided that the jet outlet openings of a group are identical to one another or emit the same type of jets.

Erfindungsgemäß kann in Weiterbildung vorgesehen sein, dass diese Nippel innerhalb der ersten Kammer auf der Rückseite der an der Strahlscheibe anliegenden Platte verlängert sind und dort einen Stutzen bilden.According to the invention, it can be provided in a further development that these nipples are extended within the first chamber on the rear side of the plate resting against the jet disk and form a connecting piece there.

Erfindungsgemäß kann das Brausekopfgehäuse beispielsweise in der Mitte noch eine Einrichtung zur Bildung von Massagestrahlen aufweisen, die eine weitere Kammer zur Versorgung mit Wasser enthält.According to the invention, the shower head housing can also have, for example in the middle, a device for forming massage jets which contains a further chamber for supplying water.

Die Figur 1 zeigt einen Längsschnitt durch eine Handbrause. Die Handbrause enthält einen Griff 1, der an einem Brausekopfgehäuse 2 angebracht ist. An dem Ende des Griffs 1 ist ein Wassereinlass 3 vorhanden. An ein Außengewinde 4 eines Kanals 5 kann eine Überwurfmutter eines Brauseschlauchs angeschraubt werden.the Figure 1 shows a longitudinal section through a hand shower. The hand shower contains a handle 1 which is attached to a shower head housing 2. At the end of the handle 1 there is a water inlet 3. A union nut of a shower hose can be screwed onto an external thread 4 of a channel 5.

Das Brausekopfgehäuse 2 enthält eine Rückwand 6 und dieser gegenüberliegend eine Strahlscheibe 7. In der Strahlscheibe 7 gibt es eine Vielzahl von Strahlaustrittsöffnungen 8 und 8a, die von Nippeln 9, 17 aus elastomerem Material gebildet sind. Die Nippel 9, 17 sind an einem flachen Element 10 angeformt, das auf der Innenseite der Strahlscheibe 7 anliegt. Die Nippel 9, 17 ragen etwas über die Außenseite der Strahlscheibe 7 hinaus, stehen also etwas vor. Sie enthalten in ihrem Inneren einen Durchgang 11.The shower head housing 2 contains a rear wall 6 and opposite this a jet disk 7. In the jet disk 7 there are a plurality of jet outlet openings 8 and 8a, which are formed by nipples 9, 17 made of elastomeric material. The nipples 9, 17 are formed on a flat element 10, which is on the inside the jet disk 7 is applied. The nipples 9, 17 protrude somewhat beyond the outside of the jet disk 7, so they protrude somewhat. They contain a passage 11 in their interior.

Die Öffnungen 8 und 8a sind über die ganze Fläche der Strahlscheibe gleichmäßig verteilt, wobei die Öffnungen 8 mit den Nippeln 9 und die Öffnungen 8a mit den Nippeln 17 korrespondieren.The openings 8 and 8a are evenly distributed over the entire surface of the jet disk, the openings 8 corresponding to the nipples 9 and the openings 8a to the nipples 17 corresponding.

Unmittelbar hinter der an der Strahlscheibe 7 anliegenden Platte 10 aus elastomerem Material ist eine erste Kammer 12 gebildet, aus der die Nippel 9 herausführen. Die Kammer 12 wird von einer angenähert parallel zur Strahlscheibe 7 verlaufenden Trennwand 13 begrenzt. In die Kammer 12 führt eine Wasserführung durch einen Kanal 14. Zwischen dem an den Einlass 3 in das Brausekopfgehäuse 2 anschließenden Kanal 5 und dem Kanal 14 ist ein Umschaltventil 15 angeordnet, das mithilfe einer Taste 16 bedient wird. Die Taste 16 ist im Übergangsbereich zwischen dem Griff 1 und der Strahlscheibe 7 angeordnet, so dass ein Benutzer sie mit dem Daumen der Hand betätigen kann, mit der er die Brause hält.Immediately behind the plate 10 made of elastomeric material resting against the jet disk 7, a first chamber 12 is formed, from which the nipples 9 lead out. The chamber 12 is delimited by a partition 13 running approximately parallel to the jet disk 7. A water duct leads into the chamber 12 through a channel 14. Between the channel 5 adjoining the inlet 3 in the shower head housing 2 and the channel 14, a switch valve 15 is arranged, which is operated with the aid of a button 16. The button 16 is arranged in the transition area between the handle 1 and the jet disk 7 so that a user can operate it with the thumb of the hand with which he is holding the shower head.

In der Position des Umschaltventils 15, die in Figur 1 dargestellt ist, ist die Wasserführung 5, 14 mit der erwähnten Kammer 12 verbunden. Das in die Brause einströmende Wasser gelangt also aus den Strahlaustrittsöffnungen 8a dieser Kammer 12 in den Bereich vor der Strahlscheibe 7.In the position of the switching valve 15 shown in Figure 1 is shown, the water guide 5, 14 is connected to the chamber 12 mentioned. The water flowing into the shower therefore reaches the area in front of the jet disk 7 from the jet outlet openings 8a of this chamber 12.

Aus der Strahlscheibe 7 ragen, wie gesagt, neben den Nippeln 9 die Nippel 17 heraus, die im Gegensatz zu den Nippeln 9 auf der der Strahlscheibe 7 abgewandten Rückseite der Platte 10 eine Verlängerung 18 bilden. In diese Verlängerung 18 greifen Stutzen 19 ein, die an der Trennwand 13 angeformt sind und die durchgehende Öffnungen aufweisen. Hinter der Trennwand 13 ist eine weitere Kammer 21 gebildet, die je nach Stellung des Umschaltventils 15 ebenfalls mit der Wasserführung in Verbindung stehen kann. Falls die Kammer 21 mit dem Einlass 3 in Verbindung steht, gelangt das Wasser aus der zweiten Kammer 21 über die Stutzen 19 in die Nippel 17 und tritt dann durch diese Nippel 17 bzw. die zugehörigen Öffnungen 8 aus der Strahlscheibe 7 aus.As mentioned, the nipples 17 protrude from the jet disk 7 in addition to the nipples 9 and, in contrast to the nipples 9, form an extension 18 on the rear side of the plate 10 facing away from the jet disk 7. Nozzles 19, which are formed on the partition 13 and which have through openings, engage in this extension 18. A further chamber 21 is formed behind the partition 13, which, depending on the position of the switching valve 15, can also be connected to the water supply. If the chamber 21 is connected to the inlet 3, the water from the second chamber 21 reaches the nipple 17 via the nozzle 19 and then exits the jet disk 7 through this nipple 17 or the associated openings 8.

In der Figur 2 ist diese zweite Kammer 21 ebenfalls zu sehen, sowie die unterschiedlichen Arten von Nippeln 9 bzw. 17.In the Figure 2 this second chamber 21 can also be seen, as well as the different types of nipples 9 and 17, respectively.

In der Mitte der Strahlscheibe sind mehrere Einrichtungen 22 zur Abgabe von Massagestrahlen angeordnet.In the middle of the jet disk, several devices 22 for emitting massage jets are arranged.

In der Figur 3 ist ein Schnitt dargestellt, bei dem die Wasserführung über einen Abschnitt 23 mit der hinteren Kammer 21 in Verbindung steht. In dieser Position des Umschaltventils 15 tritt das Wasser also nur durch die mit der hinteren Kammer 21 verbundenen Nippel 17 aus. Die vordere Kammer 12 steht nicht mit dem Wassereinlass 3 in Verbindung, so dass aus den der vorderen Kammer zugeordneten Strahlaustrittsöffnungen 8a kein Wasser austritt.In the Figure 3 a section is shown in which the water guide is connected to the rear chamber 21 via a section 23. In this position of the switching valve 15, the water only exits through the nipple 17 connected to the rear chamber 21. The front chamber 12 is not connected to the water inlet 3, so that no water emerges from the jet outlet openings 8a assigned to the front chamber.

Bei der in den Figuren 1 bis 3 dargestellten Ausführungsform der erfindungsgemäßen Brause sind die Strahlaustrittsöffnungen 8a, 8 jeweils nur einer Kammer 12 bzw. 21 zugeordnet. Jede Strahlaustrittsöffnung ist also entweder der vorderen Kammer 12, also der näher an der Strahlscheibe 7 angeordneten Kammer, zugeordnet, oder der hinteren Kammer 21, die von der vorderen Kammer durch die Trennwand 13 getrennt ist. Dabei sind die Kammern 12, 21 über die Wasserführung strömungstechnisch parallel mit dem Wassereinlass 3 gekoppelt.In the case of the Figures 1 to 3 The embodiment of the shower according to the invention shown here, the jet outlet openings 8a, 8 are each assigned to only one chamber 12 and 21, respectively. Each jet outlet opening is therefore assigned either to the front chamber 12, that is to say to the chamber arranged closer to the jet disk 7, or to the rear chamber 21, which is separated from the front chamber by the partition 13. The chambers 12, 21 are fluidically coupled in parallel to the water inlet 3 via the water guide.

Die Figuren 4 und 5 zeigen eine modifizierte Ausführungsform.the Figures 4 and 5 show a modified embodiment.

Das Brausekopfgehäuse hat wie bei der vorhergehenden Ausführungsform eine Strahlscheibe 7 und eine Rückwand 6. Auf der Innenseite der Strahlscheibe 7 liegt ein flächiges Element 10 aus elastomerem Material, an dem Nippel 9 angeformt sind. Diese bilden Strahlaustrittsöffnungen 8. Alle Nippel 9 verlaufen auf der Innenseite des Elements 10 bündig mit diesem. Hinter der Strahlscheibe 7 ist die erste Kammer 12 gebildet, die von der Trennwand 13 begrenzt ist. Hinter der Trennwand 13 ist die zweite Kammer 21 gebildet. Auf der Vorderseite der Trennwand 13 münden kurze Stutzen 19, die aber innerhalb der Kammer 12 enden.As in the previous embodiment, the shower head housing has a jet disk 7 and a rear wall 6. On the inside of the jet disk 7 is a flat element 10 made of elastomeric material on which nipples 9 are molded. These form jet outlet openings 8. All nipples 9 run on the inside of the element 10 flush with the latter. The first chamber 12, which is delimited by the partition 13, is formed behind the jet disk 7. The second chamber 21 is formed behind the partition 13. Short nozzles 19 open on the front of the partition wall 13, but they end inside the chamber 12.

Die Stutzen 19 bilden Strahlaustrittsöffnungen aus der hinteren Kammer 21, die gegenüber den Nippeln 9 ausgerichtet sind, so dass aus der hinteren Kammer 21 austretenden Strahlen durch die Nippel 9 ins Freie gelangen können. Wiederum sind die Kammern 12, 21 über das Umschaltventil strömungstechnisch parallel an die Wasserführung angekoppelt.The nozzles 19 form jet outlet openings from the rear chamber 21, which are aligned with respect to the nipples 9, so that rays emerging from the rear chamber 21 can pass through the nipples 9 into the open. Again, the chambers 12, 21 are fluidically coupled in parallel to the water supply via the switching valve.

Wenn die Wasserführung mithilfe des Umschaltventils so eingestellt ist, dass die vordere Kammer 12 mit dem Einlass 3 in Verbindung steht, treten Strahlen aus allen Strahlaustrittsöffnungen 8 aus. Dies ist in Figur 4 dargestellt. Wird dagegen das Umschaltventil so eingestellt, dass der Einlass 3 mit der hinteren Kammer 21 in Verbindung steht, so treten Strahlen nur aus denjenigen Strahlaustrittsöffnungen 8 aus, hinter denen die Stutzen 19 der Trennwand 13 aus der zweiten Kammer 21 angeordnet sind. Dies zeigt die Figur 5.If the water flow is adjusted with the aid of the switching valve in such a way that the front chamber 12 is in communication with the inlet 3, jets emerge from all jet outlet openings 8. This is in Figure 4 shown. If, on the other hand, the switching valve is set so that the inlet 3 is connected to the rear chamber 21, then jets only exit from those jet outlet openings 8 behind which the nozzle 19 of the partition 13 from the second chamber 21 are arranged. This shows the Figure 5 .

Das Zusammenwirken der Nippel 17 mit den Stutzen 19 der Trennwand 13, worauf in Figur 1 und Figur 2 hingewiesen wurde, geht genauer aus Figur 6 hervor. Hinter der Strahlscheibe 7 verläuft angenähert parallel die Trennwand 13. Zwischen beiden ist die vordere Kammer 12 gebildet. Die Strahlscheibe 7 weist Löcher 24 auf. Durch die Löcher 24 greifen die Nippel 9 bzw. 17 hindurch. Da die Nippel 9 bzw. 17 aus elastomerem Material bestehen, dichten sie gleichzeitig die Löcher 24 ab, so dass Wasser aus der ersten Kammer 12 nur durch die Nippel 9 austreten kann. Die Matte 10 aus elastomerem Material liegt flächig auf der Innenseite der Strahlscheibe 7 an. Die Nippel 17 haben auf der Innenseite der Matte 10 den Stutzen 18 als rückwärtige Fortsetzung der Nippel 17.The interaction of the nipple 17 with the nozzle 19 of the partition 13, whereupon in Figure 1 and Figure 2 was pointed out, is more precise Figure 6 emerged. The partition 13 runs approximately parallel behind the jet disk 7. The front chamber 12 is formed between the two. The jet disk 7 has holes 24. The nipples 9 and 17 reach through the holes 24. Since the nipples 9 and 17 are made of elastomeric material, they at the same time seal the holes 24 so that water can only exit from the first chamber 12 through the nipples 9. The mat 10 made of elastomeric material lies flat on the inside of the jet disk 7. On the inside of the mat 10, the nipples 17 have the connecting piece 18 as a rearward continuation of the nipples 17.

Auf der Vorderseite der Trennwand 13 sind Stutzen 19 gebildet, die einen Kanal 25 bilden. Die Stutzen 19 greifen in die rückwärtige Verlängerung 18 der Nippel 17 einen. Sie liegen an der Innenseite der Verlängerung 18 unter Spannung an, so dass durch das Material der Verlängerung 18 auch hier eine Abdichtung erfolgt.On the front side of the partition wall 13, nozzles 19 are formed, which form a channel 25. The nozzle 19 engage in the rear extension 18 of the Nipple 17 one. They are under tension on the inside of the extension 18, so that the material of the extension 18 also provides a seal here.

Hinter der Trennwand 13 ist die zweite Kammer 21 gebildet, die durch ein Bauteil 26 des Brausekopfgehäuses abgeschlossen wird.Behind the partition 13, the second chamber 21 is formed, which is closed off by a component 26 of the shower head housing.

Beim Zusammensetzen des Brausekopfgehäuses wird zunächst die Matte 10 mit ihren Nippeln 9, 17 auf die Innenseite der Strahlscheibe 17 gelegt. Anschließend wird die Trennwand 13 von der Rückseite her aufgesetzt und mit den Stutzen 19 in die rückwärtige Verlängerung 18 der Nippel 17 eingesetzt.When assembling the shower head housing, the mat 10 with its nipples 9, 17 is first placed on the inside of the jet disk 17. Subsequently, the partition 13 is placed from the rear and inserted with the nozzle 19 into the rear extension 18 of the nipple 17.

Die Figur 7 zeigt eine perspektivische Ansicht einer Handbrause mit dem Griff 1, der Strahlscheibe 7 und dem Brausekopfgehäuse 2. Die Strahlaustrittsöffnungen 8 und 8a sind in mehreren ineinander geschachtelten Ringen angeordnet. Durch die Anordnung der beiden Kammern 12 und 21 hintereinander wird es möglich, dass innerhalb jedes Rings sich die Nippel 9 und 17 abwechseln. Bei der Ausführungsform der Figur 4 und 5 können sich ebenfalls die Nippel 9, hinter denen ein Stutzen 19 angeordnet ist, und die Nippel 9 ohne einen solchen Stutzen 19 abwechseln. Es wird auf diese Weise möglich, die unterschiedlichen Strahlarten, für die die beiden strömungstechnisch parallel angeordneten Kammern 12, 21 zuständig sind, möglichst gleichmäßig über die gesamte Fläche der Strahlscheibe zu verteilen.the Figure 7 shows a perspective view of a hand shower with the handle 1, the jet disk 7 and the shower head housing 2. The jet outlet openings 8 and 8a are arranged in several nested rings. The arrangement of the two chambers 12 and 21 one behind the other makes it possible for the nipples 9 and 17 to alternate within each ring. In the embodiment of Figures 4 and 5 The nipple 9, behind which a connecting piece 19 is arranged, and the nipple 9 without such a connecting piece 19 can also alternate. In this way, it becomes possible to distribute the different jet types, for which the two chambers 12, 21, which are arranged in parallel in terms of flow technology, as evenly as possible over the entire surface of the jet disk.

Der Schnitt der Figur 8 zeigt beispielsweise an dem äußeren Ring von Strahlaustrittsöffnungen 8 und 8a, wie sich unterschiedliche Nippel 9, 17 abwechseln.The cut of the Figure 8 shows, for example, on the outer ring of jet outlet openings 8 and 8a, how different nipples 9, 17 alternate.
