Abstract

The device has shower head housing (2) comprising a jet disk (7) having a number of jet outlet openings (8, 8a), which form a set of groups of jet outlet openings. A water conduit (5) moves from a water inlet (3) into the shower head housing. Two chambers (12, 21) are formed in the shower head housing and fluidly coupled in parallel to the water inlet through the water conduit. The chambers supply water to the groups of jet outlet openings, and are arranged consecutively behind the jet disk in the shower head housing. The jet outlet openings are arranged identical to each other.

Description

Die Erfindung geht aus von einer Brause, beispielsweise einer Handbrause oder einer Kopfbrause.The invention relates to a shower, such as a hand shower or overhead shower.

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.There are already known showerheads, which have in their jet disk a plurality of jet outlet openings, from which, for example, two different beams can be emitted, such as hard or soft beams. You can switch between the two spray types by a manually operated switch.

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 exit openings are arranged, for example, in concentric rings, the different types of jet being combined in such a way that one ring emits one type of radiation and the next ring the other type of radiation. To achieve this, annular chambers are arranged behind the jet disk, which each extend to the back of the jet disk. It is therefore an arrangement of the chambers next to each other.

Bei einem bekannten Brausekopf dieser Art ( GB 2 270 859 A ) weist die Strahlscheibe mehrere konzentrische kreisförmige Ringe von Strahlaustrittsöffnungen auf. Der äußere Ring gibt belüftete Strahlen ab, und ein innerer Ring gibt Massagestrahlen ab.In a known shower head of this type ( GB 2 270 859 A ), the jet disk on a plurality of concentric circular rings of jet outlet openings. The outer ring emits aerated rays, and an inner ring emits massage jets.

Für eine solche Anordnung von Brausestrahlen ergibt sich beim Umschalten zwischen den verschiedenen Strahlarten auch eine Änderung des Strahlbilds, da im einen Fall die Strahlen im Bereich des Umfangs des Brausekopfs abgegeben werden, während sie nach dem Umschalten nur noch in der Mitte des Brausekopfs abgegeben werden.For such an arrangement of effervescent jets results in switching between the different types of jet, a change in the spray pattern, as in one case, the rays are delivered in the region of the circumference of the shower head, while they are delivered after switching only in the middle of the shower head.

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 there is disclosed a shower head of a similar type in which a first irrigation chamber with an associated set of first water outlets is separated by an annular bulkhead from a second irrigation chamber with an associated set of second water outlets. The two irrigation chambers adjoining a jet exit disc with the water outlets are preceded by a water splitting element, which has two water splitting openings, one of which being switchable, one open and the other closed to deliver water via an inlet channel into an antechamber in front of the water splitting openings. switchable to the first or second irrigation chamber supply.

Der Erfindung liegt die Aufgabe zu Grunde, eine Brause 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.The invention is based on the object to provide a shower, in which the exit jets can be distributed as evenly as possible over the entire exit surface of the jet disk, so that when switching between different beams, the overall picture is changed as little as possible.

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 with the im Claim 1 mentioned features. Further developments of the invention are the subject of dependent claims. The showerhead can be a hand shower, 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 thus contains at least two chambers, which are responsible for the water supply to the jet outlet openings. At least one of these two chambers is responsible for the water supply only a group of jet outlet openings in the jet disk.

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 cost of creating the showerhead housing is low and thereby relatively easy to distribute the associated exit jets evenly over the exit surface of the jet disk.

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 a group of jet outlets, so the other chamber can supply both groups of jet outlets with water.

In Weiterbildung der Erfindung kann vorgesehen sein, dass beide Kammern ausschließlich für die Wasserversorgung jeweils einer Gruppe von Strahlaustrittsöffnungen zuständig sind.In a development of the invention, it can be provided that both chambers are exclusively responsible for supplying water to a 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.In the arrangement of two water supply chambers one behind the other, it makes sense and is proposed by the invention that a chamber is arranged directly behind the jet disk, so that a group of jet outlet openings directly into this arranged behind the jet disk and thus leads to be designated as a chamber 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 makes sense to allow a simple structure, the rear chamber is located directly behind the front chamber, so separated from this only by a partition.

Insbesondere in diesem Fall kann erfindungsgemäß vorgesehen sein, dass die Strahlaustrittsöffnungen einer Gruppe von Strahlaustrittsöffnungen durch Kanäle mit der hinteren Kammer in Verbindung stehen, die durch die vordere Kammer hindurch gehen. Das Wasser tritt also aus der hinteren Kammer durch für jede Strahlaustrittsöffnung einen eigenen Kanal aus der Brause aus.In particular, in this case, it may be provided according to the invention that the jet outlet openings of a group of jet outlet openings communicate with the rear chamber through channels which pass through the front chamber. The water thus emerges from the rear chamber for each jet outlet opening its own channel from the shower.

Eine weitere Möglichkeit kann darin bestehen, dass die hintere Kammer eigene Strahlaustrittsöffnungen aufweist, 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 die vordere Kammer durchqueren und nur durch jeweils diejenigen Strahlaustrittsöffnungen austreten, die der hinteren Kammer zugeordnet sind.Another possibility may be that the rear chamber has its own jet outlet openings, which are aligned concentrically with respect to jet outlet openings of the jet disk and have a smaller diameter. The water leaving the rear chamber therefore emerges as individual jets which pass through the front chamber and exit only through those jet outlet openings which are assigned to the rear chamber.

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 showerhead can have a manually actuable changeover valve in order to bring one of the two chambers into contact with the water inlet into the showerhead housing. Thus, it can be switched between the different water jets, 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. Erfindungsgemäß kann vorgesehen sein, dass die Strahlaustrittsöffnungen beider Gruppen von Strahlaustrittsöffnungen in der Strahlscheibe gemischt bzw. gleichmäßig verteilt angeordnet sind.But it is also possible to design the switching valve so that it also includes the possibility of water supply to both chambers simultaneously. Such a possibility is also useful if the two groups of jet outlet openings emit the same type of water jets. In this way, one can regulate the amount of water to be dispensed to some extent. According to the invention it can be provided that the jet outlet openings of both groups of jet outlet openings are mixed in the jet disk or distributed uniformly.

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 may be provided that the jet outlet openings of both groups of jet outlet openings are identical, in particular when the switchover valve is intended to switch over between supplying one group on the one hand and supplying both groups at the same time. Then, the supply of only one group of jet outlet openings can be regarded as a savings 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 types of jet.

Es kann erfindungsgemäß vorgesehen sein, dass die Strahlaustrittsöffnungen einer Gruppe untereinander identisch sind bzw. die gleiche Art von Strahlen ausgeben.It can be inventively provided that the jet outlet openings of a group are identical to each other or spend the same kind of rays.

Zur Ermöglichung eines einfachen Aufbaus kann erfindungsgemäß in Weiterbildung vorgesehen sein, dass die Strahlaustrittsöffnungen, vorzugsweise beider Gruppen, durch Nippel aus elastomerem Material gebildet sind, die an einer gemeinsamen an der Innenseite der Strahlscheibe anliegenden Platte aus diesem Material angeformt sind.

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 FIG. 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, a water inlet 3 is present. At an external thread 4 of a channel 5, a union nut of a shower hose can be screwed.

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 includes a rear wall 6 and this opposite 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 of elastomeric material. The nipples 9, 17 are formed on a flat element 10, which rests on the inside of the jet disk 7. The nipples 9, 17 protrude slightly beyond the outside of the jet disk 7, so are somewhat ahead. They contain in their interior a passage 11.

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 uniformly distributed over the entire surface of the jet disk, wherein the openings 8 with the nipples 9 and the openings 8a with the nipples 17 correspond.

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 applied to the jet disk 7 plate 10 made of elastomeric material, a first chamber 12 is formed, from which the nipple 9 lead out. The chamber 12 is delimited by a partition wall 13 extending approximately parallel to the jet disk 7. In the chamber 12 performs a water flow through a channel 14. Between the adjoining the inlet 3 in the showerhead housing 2 channel 5 and the channel 14, a switching valve 15 is arranged, which is operated by means of a button 16. The button 16 is arranged in the transition region between the handle 1 and the jet disk 7, so that a user can operate them with the thumb of the hand with which he holds the shower.

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, the in FIG. 1 is shown, the water guide 5, 14 is connected to the mentioned chamber 12. The water flowing into the shower thus flows from the jet outlet openings 8a of this chamber 12 into the area in front of the jet disk 7.

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.From the jet disk 7 protrude, as I said, in addition to the nipples 9, the nipples 17, which form an extension 18 in contrast to the nipples 9 on the back of the plate 10 facing away from the jet disk 7. In this extension 18 are used stub 19, which are integrally formed on the partition wall 13 and have the through openings. Behind the partition wall 13, a further chamber 21 is formed, which may also be related to the position of the switching valve 15 with the water flow in conjunction. If the chamber 21 is in communication with the inlet 3, the water passes from the second chamber 21 via the nozzle 19 into the nipple 17 and then exits through this nipple 17 and the associated openings 8 from the jet disk 7.

In der Figur 2 ist diese zweite Kammer 21 ebenfalls zu sehen, sowie die unterschiedlichen Arten von Nippeln 9 bzw. 17.In the FIG. 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 means 22 for delivering 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 FIG. 3 is a section shown, in which the water supply via a section 23 with the rear chamber 21 in conjunction. In this position of the switching valve 15, the water therefore only exits through the nipple 17 connected to the rear chamber 21. The front chamber 12 is not in communication with the water inlet 3, so that no water escapes from the jet outlet openings 8a associated with 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 in the FIGS. 1 to 3 illustrated embodiment of the shower according to the invention, the jet outlet openings 8a, 8 each associated with only one chamber 12 and 21 respectively. Each jet outlet opening is thus 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 dividing wall 13. In this case, the chambers 12, 21 are fluidically coupled in parallel with the water inlet 3 via the water guide.

Die Figuren 4 und 5 zeigen eine modifizierte Ausführungsform.The FIGS. 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.The shower head housing has, as in the previous embodiment, a jet disk 7 and a rear wall 6. On the inside of the jet disk 7 is a sheet-like element 10 made of elastomeric material, are formed on the nipple 9. These form jet outlet openings 8. All nipples 9 extend on the inside of the element 10 flush with this. Behind the jet disk 7, the first chamber 12 is formed, which is bounded by the partition wall 13. Behind the partition wall 13, the second chamber 21 is formed. On the front of the partition wall 13 open short stub 19, but ends within 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. 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.The nozzles 19 form jet outlet openings from the rear chamber 21, which are aligned with respect to the nipples 9, so that out of the rear chamber 21 exiting rays can pass through the nipple 9 into the open. Again, the chambers 12, 21 are fluidly coupled via the switching valve to the water supply. When the water flow is adjusted by means of the switching valve so that the front chamber 12 is in communication with the inlet 3, jets emanate from all the jet outlet openings 8. This is in FIG. 4 shown. If, however, the changeover valve is adjusted so that the inlet 3 is in communication with the rear chamber 21, then jets only emerge from those jet outlet openings 8, behind which the sockets 19 of the partition 13 are arranged from the second chamber 21. This shows the FIG. 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 FIG. 1 and FIG. 2 was pointed out, goes into more detail FIG. 6 out. Behind the jet disk 7 runs approximately parallel to the partition wall 13. Between the two, the front chamber 12 is formed. The jet disk 7 has holes 24. Through the holes 24, the nipple 9 and 17 engage. Since the nipples 9 and 17 are made of elastomeric material, they simultaneously seal the holes 24, so that water can escape from the first chamber 12 only through the nipple 9. The mat 10 made of elastomeric material lies flat against the inside of the jet disk 7. The nipples 17 have on the inside of the mat 10, the nozzle 18 as a rearward continuation of the nipple 17th

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 13, nozzles 19 are formed, which form a channel 25. The nozzle 19 engage in the rearward extension 18 of the nipple 17 a. They are on the inside of the extension 18 under tension, so that by the material of the extension 18 is also a seal.

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 completed by a component 26 of the showerhead 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 first the mat 10 with its nipples 9, 17 on the inside of the jet disk 17th placed. Subsequently, the partition 13 is placed from the back and used with the nozzle 19 in the rearward 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 FIG. 7 shows a perspective view of a hand shower with the handle 1, the jet disk 7 and the showerhead housing 2. The jet outlet openings 8 and 8a are arranged in a plurality of nested rings. The arrangement of the two chambers 12 and 21 in succession makes it possible for the nipples 9 and 17 to alternate within each ring. In the embodiment of the FIGS. 4 and 5 Also, the nipple 9, behind which a nozzle 19 is arranged, and the nipple 9 without such a nozzle 19 alternate. It is possible in this way, the different types of jet, for which the two flow-parallel chambers 12, 21 are responsible, as evenly distributed 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 FIG. 8 shows, for example, on the outer ring of jet outlet openings 8 and 8a, as different nipples 9, 17 alternate.
