Description

Die Erfindung bezieht sich auf einen Duschkopf nach dem Oberbegriff des Anspruchs 1. Duschköpfe existieren in einer großen Vielfalt von Formen und Gestaltungen, funktionieren jedoch fast ausschließlich nach demselben Prinzip: Das Duschwasser wird aus der Wasserleitung in einen Verteiler-Hohlraum geleitet, aus dem es durch eine oder mehrere Öffnungen austritt, wodurch der Duschstrahl direkt geformt wird. Im einfachsten Fall gibt es nur eine große Öffnung, durch die sich das Wasser schwallartig auf die duschende Person ergießt, sog. Schwall-Duschköpfe.The invention relates to a shower head according to the preamble of claim 1. Shower heads exist in a wide variety of shapes and designs, but operate almost exclusively on the same principle: the shower water is directed from the water pipe into a distributor cavity, from which it one or more openings emerges, whereby the shower jet is formed directly. In the simplest case, there is only one large opening, through which the water pours like a shower on the showering person, so-called flood shower heads.

Im täglichen Gebrauch beliebter sind jedoch Duschköpfe mit mehreren kleinen Öffnungen, im Folgenden Düsen-Duschköpfe genannt, die entweder unter Zuhilfenahme des Leitungsdrucks einen aus mehreren Einzelstrahlen bestehenden Duschstrahl erzeugen oder das Wasser aus dem Inneren des Duschkopfes weitgehend drucklos auslaufen lassen und so einen regenartigen Duschstrahl erzeugen. Letzterer Typ erfreut sich aufgrund seines weichen, an natürlichen Regen erinnernden Strahls besonderer Beliebtheit.However, shower heads with several small openings, hereinafter referred to as nozzle shower heads, which either generate a shower jet consisting of a plurality of individual jets with the aid of line pressure or allow the water to flow out largely without pressure from the interior of the shower head and thus produce a rain-like shower jet, are more popular in daily use , The latter type is particularly popular because of its soft, reminiscent of natural rain ray.

Die Nachteile dieser Gestaltung mit mehreren Düsen sind vielfältig. Am bekanntesten ist das Problem der Verkalkung. Der nach jedem Duschvorgang an den Düsen zurückbleibende Wasserfilm trocknet ab, wobei die im Wasser gelösten Mineralien ausfallen und sich irreversibel ablagern. Dies führt über mehrere Duschvorgänge zu einer signifikanten Einengung der Düsen bis hin zu deren Verstopfung, mit entsprechendem Einfluss auf die Formung des Duschstrahls.The disadvantages of this design with multiple nozzles are many. The best known is the problem of calcification. The water film remaining on the nozzles after each shower cycle dries off, whereby the minerals dissolved in the water precipitate and irreversibly deposit. This leads to several showering events to a significant constriction of the nozzles to their constipation, with a corresponding influence on the shaping of the shower jet.

Zur ursächlichen Verhinderung der Verkalkung sind Düsen-Duschköpfe bekannt, bei denen mittels kompakter Düsenanordnungen hohe Strömungsgeschwindigkeiten und Turbulenzen erzeugt werden, wodurch Kalkablagerungen mechanisch verhindert werden. Diese verbreitet in öffentlichen Einrichtungen genutzten Duschköpfe erzeugen jedoch prinzipbedingt einen harten Duschstrahl, der von der beliebten Regenartigkeit weit entfernt ist.For the causal prevention of calcification nozzle shower heads are known in which by means of compact nozzle arrangements high flow velocities and turbulence are generated, whereby limescale deposits are mechanically prevented. However, these shower heads, which are widely used in public institutions, produce a hard shower jet that is far removed from popular rainfall.

Im Falle von Düsen-Duschköpfen wird daher meist auf sekundäre Maßnahmen zur einfachen Entfernung von Kalkablagerungen zurückgegriffen. Am verbreitetsten ist die Methode, die einzelnen Düsen aus einem Elastomer mit guten Antihafteigenschaften, z.B. Silikonkautschuk, herzustellen, so dass Kalkablagerungen durch Überstreichen der Düsen mit dem Finger gelöst werden können. Die mechanische Entfernung der harten Kalkbrocken verursacht am weichen Material jedoch Beschädigungen und trägt zu einer relativ schnellen Alterung bei.In the case of nozzle showerheads, therefore, secondary measures are usually used for the simple removal of calcium deposits. Most common is the method to produce the individual nozzles of an elastomer with good non-stick properties, such as silicone rubber, so that limescale removed by sweeping the nozzles with your finger can be. However, the mechanical removal of the hard chunks causes damage to the soft material and contributes to a relatively rapid aging.

Des Weiteren bleibt nach jedem Duschvorgang im hohlen Inneren eines Düsen-Duschkopfes Wasser zurück, welches aufgrund der relativen Abgeschlossenheit des Hohlraums nur sehr langsam abtrocknet und so das Wachstum von Keimen und Biofilmen begünstigt. Diese Keime können bei einem dann folgenden Duschvorgang teilweise durch das Duschwasser mitgerissen werden und aufgrund von Zerstäubungseffekten bei der Strahlformung als Aerosole tief in die Atemwege der duschenden Person gelangen und Infektionen auslösen.Furthermore, water remains behind after every showering process in the hollow interior of a nozzle shower head, which only dries very slowly due to the relative closeness of the cavity and thus promotes the growth of germs and biofilms. These germs can be entrained in a subsequent showering process partially by the shower water and due to atomization effects in the beam shaping as aerosols reach deep into the respiratory tract of the showering person and trigger infections.

Bei Regen-Duschköpfen mit Düsen ergeben sich zudem, wenn keine weiteren konstruktiven Maßnahmen ergriffen werden, an den Düsen kontinuierliche Wasserstrahlen, sog. Spaghetti-Strahlen, wodurch das Strahlbild nur eine beschränkte Ähnlichkeit mit natürlichem Regen aufweist. Um das Strahlbild regenähnlicher zu gestalten, müssen die Strahlen in einzelne Tropfen aufgebrochen werden, was z.B. durch Beimischung von Luft im Zulauf erreicht werden kann. Diese Luftbeimischung erzeugt jedoch im Gegenzug ein sprudelndes Geräusch, welches unter Umständen die Akustik des Duschkopfes negativ beeinflusst.In the case of rain shower heads with nozzles, moreover, if no further constructive measures are taken, there are continuous jets of water at the jets, so-called spaghetti jets, whereby the spray pattern has only a limited resemblance to natural rain. In order to make the spray pattern more rain-like, the jets need to be broken up into individual drops, e.g. can be achieved by admixing air in the inlet. However, this addition of air generates in return a bubbling noise, which may adversely affect the acoustics of the shower head.

Hinzu kommt, dass die Notwendigkeit, bei der Herstellung einen Hohlraum mit kleinen Öffnungen als Düsen zu erzeugen, die Wahl der wirtschaftlich verwendbaren Materialien erheblich einschränkt. Es kommen für die Massenproduktion von solchen Duschköpfen prinzipiell nur Materialien in Frage, aus denen sich in wirtschaftlicher Weise stabile Hohlkörper mit kleinen Bohrungen erzeugen lassen. Stein, Glas oder Holz beispielsweise erfüllen diese Anforderungen im Allgemeinen nicht.In addition, the need to create a void with small orifices as nozzles during manufacture significantly limits the choice of economically useful materials. For the mass production of such shower heads, in principle, only materials are suitable from which economically viable hollow bodies with small bores can be produced. Stone, glass or wood, for example, generally do not meet these requirements.

Die eingangs erwähnten Schwall-Duschköpfe besitzen die genannten Nachteile bei günstiger Gestaltung nicht, der von ihnen erzeugte Duschstrahl entspricht jedoch nicht den Wünschen der breiten Masse der Konsumenten. Der kompakte Schwall trifft jeweils nur einzelne, begrenzte Bereiche des Körpers und übt auf die Einwirkungsstelle relativ große Kräfte aus. Zusammen mit der Abwesenheit jeglicher Luft im Strahl ist dies vor allem bei Einwirkung auf das Gesicht tendenziell unangenehm. Hinzu kommt, dass Schwallduschen im Allgemeinen einen sehr hohen Wasserverbrauch aufweisen.The above-mentioned surge shower heads do not have the disadvantages mentioned in a favorable design, but the shower jet generated by them does not meet the wishes of the broad mass of consumers. The compact surge meets only individual, limited areas of the body and exerts on the site of action relatively large forces. This, together with the absence of any air in the jet, tends to be uncomfortable, especially when exposed to the face. In addition, showers generally have a very high water consumption.

Eine Ausführung einer Schwalldusche beschreibt die Offenlegungsschrift US 2006/0226255 A1 . Darin wird vorgeschlagen, das Duschwasser in ein Gefäß zu leiten, aus welchem es über den Rand tritt und in zufälliger Verteilung von der Unterseite des Gefäßes abläuft. Der Wasserschwall wird dadurch teilweise aufgebrochen sowie dynamisiert und erreicht so eine größere Ähnlichkeit mit einem Wasserfall als bei normalen Schwall-Duschköpfen. Es bleibt jedoch bei den genannten Nachteilen von Schwallduschen und darüber hinaus dem Problem des nach dem Duschen im Gefäß zurückbleibenden Wassers, welches Keimwachstum begünstigt oder mittels zusätzlicher Funktionselemente nach dem Duschen abgelassen werden muss.An embodiment of a surge shower describes the published patent application US 2006/0226255 A1 , It is proposed to direct the shower water into a vessel from which it passes over the edge and runs off in random distribution from the bottom of the vessel. The rush of water is thereby partially broken and dynamized, and thus achieves a greater similarity with a waterfall than normal flood shower heads. However, it remains in the aforementioned disadvantages of showers and beyond the problem of remaining after showering in the vessel water, which favors germination or must be drained by means of additional functional elements after showering.

Zusammenfassend ist festzustellen, dass Düsen-Duschköpfe, die einen von den meisten Menschen im täglichen Gebrauch als angenehm empfundenen Duschstrahl erzeugen, deutliche Probleme aufweisen. Die Schwall-Duschköpfe sind dagegen prinzipbedingt nicht geeignet, einen angenehmen Duschstrahl zu erzeugen.In summary, nozzle showerheads, which produce a shower jet that is perceived as pleasant by most people in everyday use, clearly have problems. By contrast, the splash showerheads are not suitable in principle to produce a pleasant shower jet.

Ein Duschkopf nach dem Oberbegriff des Anspruchs 1 ist in der Offenlegungsschrift AU 2003200878 A1 offenbart. Beim dortigen Duschkopf gelangt von oben zugeführtes Duschwasser durch Sickerlöcher einer entsprechend perforierten Scheibe hindurch zu einer fluidpermeablen Absorberschicht und von dort weiter zur Abtropffläche. Die Absorberschicht besteht vorzugsweise aus einem festen, porösen und dichten Material, zum Beispiel einem Schaum, einem Nylongewebe, einer Edelstahlmatte, einem perforierten Gummimaterial oder einem Schwamm.A shower head according to the preamble of claim 1 is in the published patent application AU 2003200878 A1 disclosed. When there shower head passes from the top supplied shower water through drain holes a perforated disc corresponding to through to a fluid-permeable absorber layer and from there to the drainer. The absorber layer preferably consists of a solid, porous and dense material, for example a foam, a nylon fabric, a stainless steel mat, a perforated rubber material or a sponge.

Aufgabe der vorliegenden Erfindung ist daher die Erzeugung eines Duschkopfes, der einen weichen, regenartigen Duschstrahl abgibt, ohne die oben erwähnten Schwierigkeiten des Stands der Technik aufzuweisen.It is therefore an object of the present invention to provide a showerhead that emits a soft, rain-like jet of shower without the above-mentioned difficulties of the prior art.

Gelöst wird diese Aufgabe durch einen Duschkopf mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben, deren Wortlaut hiermit durch Verweis in die Beschreibung aufgenommen wird. Der erfindungsgemäße Duschkopf benötigt keinen Verteiler-Hohlraum mit Düsen. Um ohne diese Konstruktionselemente einen regenartigen Duschstrahl zu erzeugen, wird vorgeschlagen, den Duschkopf als Körper mit mindestens einer im Wesentlichen in Schwerkraftrichtung nach unten weisenden Abtropffläche auszuführen. Das Duschwasser wird unter Ausnutzung der Adhäsionskräfte des Wassers auf diese Fläche geleitet. Auf der Abtropffläche befinden sich eine z.B. geometrische oder oberflächenphysikalisch wirksame Struktur, die das Wasser lokal zum Abtropfen bringt, so dass durch eine geeignete Gestaltung und verteilte Anordnung der Elemente der Abtropfstruktur der gewünschte regenartige Duschstrahl erzeugt werden kann. Geometrische Abtropfstrukturen können dabei Ausformungen eines betreffenden Teils des Duschkopfes selbst oder daran angesetzt sein.This object is achieved by a shower head having the features of claim 1. Advantageous developments of the invention are specified in the subclaims, the wording of which is hereby incorporated by reference into the description. The shower head according to the invention does not require a distributor cavity with nozzles. In order to produce a rain-like shower jet without these construction elements, it is proposed to carry out the shower head as a body with at least one draining surface pointing downwards essentially in the direction of gravity. The shower water is directed to this surface by utilizing the adhesion forces of the water. On the draining surface there is a geometric or surface-physically active structure, for example, which causes the water to drip locally, so that by suitable design and distributed arrangement of the elements of the drip structure the desired rain-like shower jet can be generated. Geometric drip structures can be formed on the part of the shower head itself or on it.

Prinzipbedingt ergibt sich dabei ohne weitere konstruktive Maßnahmen ein aus einzelnen Tropfen bestehender, natürlichem Regen sehr ähnlicher Strahl.Due to the principle, this results in a very similar jet of individual drops of natural rain without further constructive measures.

Durch diese Gestaltung wird dem Problem der Verkalkung wirkungsvoll begegnet. Kalkablagerungen können sich zwar weiterhin bilden, treten bzw. tragen jedoch auf den Abtropfstrukturen auf und stören dadurch nicht deren Funktionsprinzip, sondern können es sogar unterstützen, z.B. wenn die Strukturen geometrisch den Stalaktiten einer Tropfsteinhöhle ähneln. Hinzu kommt, dass sich Kalkablagerungen bei Duschköpfen nach diesem Prinzip außen befinden und nicht in feinen Bohrungen, für eine wirksame Entfernung mit mechanischen oder chemischen Maßnahmen also wesentlich besser zugänglich sind.This design effectively counteracts the problem of calcification. Lime deposits may continue to form, but do occur on the drip structures and thereby not interfere with their operating principle, but may even support it, e.g. if the structures are geometrically similar to the stalactites of a stalactite cave. In addition, lime deposits on shower heads are based on this principle on the outside and not in fine holes, so much more accessible for effective removal with mechanical or chemical measures.

Der Wegfall der Notwendigkeit eines Verteiler-Hohlraums eröffnet die Möglichkeit der Gestaltung ohne innenliegende oder schlecht zugängliche wasserbenetzte Flächen, was eine schnelle Abtrocknung des gesamten Duschkopfes begünstigt und so die Vermehrung von Keimen und Biofilmen verhindert.The elimination of the need for a distributor cavity opens up the possibility of designing without interior or poorly accessible water wetted surfaces, which promotes rapid drying of the entire shower head and thus prevents the proliferation of germs and biofilms.

Weiterhin ist die Auswahl der sinnvoll und wirtschaftlich verwendbaren Materialien bei Duschköpfen nach dieser Erfindung erheblich erweitert. Durch die Möglichkeit der Gestaltung als Vollkörper mit außenliegenden Strukturen sind einerseits z.B. Luxusausführungen aus Granit oder Marmor denkbar, andererseits aber auch sehr kostengünstige oder leichte Ausführungen z.B. als Kunststoff-Blasformteil oder aus Schaumstoff.Furthermore, the selection of useful and economically usable materials shower heads according to this invention is considerably expanded. Due to the possibility of designing as a solid body with external structures, on the one hand, e.g. Luxury designs of granite or marble conceivable, but on the other hand, very inexpensive or lightweight versions, for. as a plastic blow molding or foam.

Hinzu kommt, dass bei Duschköpfen nach dieser Erfindung allein die Schwerkraft für die Verteilung des Wassers und das verteilte Abtropfen sorgen kann, so dass für die Erzeugung eines über eine Fläche verteilten, gleichmäßigen Strahlbildes kein Überdruck notwendig ist. Dadurch sind Duschköpfe nach diesem Prinzip besser als herkömmliche Regen-Duschköpfe für Installationen geeignet, bei denen nur ein sehr geringer Wasserdruck in der Versorgungsleitung zur Verfügung steht.In addition, with shower heads according to this invention, gravity alone can provide for the distribution of the water and the distributed dripping, so that no overpressure is necessary for the generation of a uniform jet pattern distributed over a surface. This shower heads are on this principle better than conventional rain showerheads suitable for installations in which only a very low water pressure in the supply line is available.

Gemäß einem Aspekt der Erfindung wird das Wasser zunächst auf eine an die Abtropffläche angrenzende oder in sie übergehende Fläche geleitet, wo es sich so verteilen kann, dass der Übertritt auf die Abtropffläche in der gewünschten Weise stattfindet. Dies vereinfacht die Konstruktion dahingehend, dass das Wasser sehr einfach z.B. auf die Oberseite des Teils geleitet werden kann, das die Abtropffläche aufweist, und um einen gerundeten Rand des Körpers herum verteilt auf die Abtropffläche laufen kann.According to one aspect of the invention, the water is first directed to an area adjacent to or passing into the drainer where it may spread so as to transfer to the drainer in the desired manner. This simplifies the construction in that the water is very simply e.g. can be directed to the top of the part, which has the draining surface, and can run around a rounded edge of the body distributed on the draining surface.

Gemäß einem weiteren Aspekt der Erfindung kann mittels Veränderung des Wasservolumenstroms zwischen zwei verschiedenen Strahlarten umgeschaltet werden. Dazu kann der Übergang zwischen dem Wasserzulauf und der Abtropffläche z.B. mit einer Abreißkante so gestaltet werden, dass bei Überschreitung eines bestimmten Schwellwerts des Wasservolumenstroms die Adhäsion abreißt und das Wasser sich direkt in einem Schwall auf die duschende Person ergießt, anstatt auf die Abtropffläche weiterzulaufen. Auf diese Weise kann die duschende Person den Duschvorgang mit einem angenehmen Regenstrahl beginnen, der sich bei sparsamen, niedrigen Durchflüssen ergibt, und jederzeit, z.B. zum Ausspülen von Shampoo aus den Haaren, den Durchfluss erhöhen. Am Duschkopf ergibt sich in der Folge automatisch ein Schwallstrahl, der für diesen Zweck ideal ist. Ein Absenken des Durchflusses bewirkt eine Rückkehr zum Regenstrahl. Zur Bereitstellung der zwei Strahlarten ist dabei kein Umschaltventil und keine zweite Wasser-Steigleitung zum Duschkopf notwendig, was gegenüber dem Stand der Technik die Installation vereinfacht und die Bedienung intuitiver gestaltet.According to another aspect of the invention, it is possible to switch between two different types of jet by changing the water volume flow. For this purpose, the transition between the water inlet and the drainer, e.g. with a tear-off edge designed so that when exceeding a certain threshold value of the water volume flow, the adhesion breaks off and the water pours directly in a surge on the showering person, rather than continue to run on the draining surface. In this way, the showering person can begin the showering process with a pleasant jet of rain, resulting in economical, low flow rates, and at any time, e.g. to rinse shampoo off your hair, increase the flow. At the shower head, the result is automatically a surge jet, which is ideal for this purpose. Lowering the flow causes a return to the rain jet. To provide the two spray modes, no switching valve and no second water riser to the shower head is necessary, which simplifies the installation compared to the prior art and makes the operation more intuitive.

Patentanspruch 2 schlägt zusätzlich vor, auf der Verteilerfläche eine Struktur z.B. geometrischer oder oberflächenphysikalischer (hydrophob/hydrophil) Art vorzusehen, um die für das Funktionsprinzip gewünschte Verteilung des Wassers zu gewährleisten. Solche Strukturen können vorteilhaft sein, um die Verteilung des Wassers vor dem Übertritt auf die Abtropffläche gezielt zu beeinflussen.Claim 2 additionally proposes a structure on the distribution surface, e.g. geometric or surface-physical (hydrophobic / hydrophilic) type to provide the desired distribution of the water for the functional principle. Such structures may be advantageous in order to influence the distribution of the water before the transfer to the draining surface.

Patentanspruch 3 schlägt vor, geometrischen Abtropfstrukturen wenigstens bereichsweise eine stalaktitenähnliche Form zu geben. Diese den Strukturen einer Tropfsteinhöhle entlehnte Form funktioniert besonders zuverlässig und ermöglicht eine ästhetisch wertvolle, natürliche Gestaltung.Claim 3 proposes to give geometric Abtropfstrukturen at least partially a stalactite-like shape. This form borrowed from the structures of a stalactite cave works very reliably and allows an aesthetically valuable, natural design.

Patentanspruch 4 schlägt vor, die Abtropffläche wenigstens bereichsweise angelehnt an eine Gesteins-Bruchfläche zu gestalten. Mit dieser Formgebung kann ebenfalls ein ästhetisch wünschenswertes Aussehen ähnlich einem unbehauenen, roh gebrochenen Stück Stein erzielt werden.Claim 4 proposes to make the drainer at least partially ajar against a rock fracture surface. With this shaping can also be an aesthetically desirable Appearance similar to an unhenched, raw broken piece of stone can be achieved.

Patentanspruch 5 schlägt vor, in einer oder mehreren der wasserbenetzten Flächen Lichtquellen zu integrieren. So integrierte Lichtquellen werden vom Wasser überflossen, wodurch das Licht dynamisch gebrochen wird und Kaustiken sowie andere Lichteffekte erzeugt, die denen eines Schwimmbades mit Unterwasserbeleuchtung ähneln.Claim 5 proposes to integrate in one or more of the water-wetted surfaces light sources. The water is overflowed into such integrated light sources, which dynamically refracts the light and creates caustics and other lighting effects similar to those of a swimming pool with underwater lighting.

Patentanspruch 6 schlägt vor, den die Abtropffläche aufweisenden Teil des Duschkopfes an dem Teil zu montieren, welches den Wasserzulauf enthält. In Kombination mit einer Gestaltung nach dem vorgenannten Erfindungsaspekt entspricht diese Bauform in ihrer äußeren Erscheinung am ehesten derjenigen von Duschköpfen nach dem Stand der Technik, bei denen der Duschkopf mit Hohlraum und Düsen am Wasserzulaufrohr montiert ist. Aufgrund des neuen Funktionsprinzips entfällt jedoch die Notwendigkeit, an der Übergangsstelle zwischen Wasserleitung und Duschkopf eine Abdichtung vorzusehen. Dies ist vorteilhaft, weil die verbreitet an dieser Stelle eingesetzten Weichdichtungen altern und mit der Zeit undicht werden können.Claim 6 proposes to assemble the part of the shower head having the draining surface on the part which contains the water inlet. In combination with a design according to the aforementioned aspect of the invention, this design corresponds in appearance to the closest to that of shower heads according to the prior art, in which the shower head with cavity and nozzles is mounted on the water inlet pipe. Due to the new functional principle, however, eliminates the need to provide a seal at the transition point between the water pipe and the shower head. This is advantageous because the soft seals commonly used at this point age and become leaky over time.

Patentanspruch 7 bezieht sich auf Gestaltungen, bei denen der Duschkopf auch den Wasserzulauf enthält. Eine solche Gestaltung ergibt sich z.B., wenn eine Installation mit einem hohen Integrationsgrad aus einem Teil ausgeführt ist oder wenn eine große, überkragende Wandinstallation auch die für den Wasserzulauf benötigten Kanäle in sich aufnimmt, um sie ästhetisch anspruchsvoll zu verstecken.Claim 7 relates to designs in which the shower head also contains the water inlet. Such a design results, for example, when an installation with a high degree of integration is made of one part or when a large, overhanging wall installation also absorbs the channels required for the water inlet in order to hide them aesthetically demanding.

Patentanspruch 8 nutzt über Anspruch 6 hinausgehend die Tatsache, dass mit wegfallender Dichtung auch die Notwendigkeit wegfällt, eine Anpresskraft auf diese Dichtung zu generieren, was sehr einfache werkzeugfreie Montagen des Duschkopfes z.B. mittels magnetischer Anziehung ermöglicht. Ein magnetisch befestigter Duschkopf könnte zu Reinigungszwecken sehr leicht abgenommen werden oder es könnte sehr einfach aus einer Auswahl verschieden gestalteter kompatibler Duschköpfe nach Wunsch gewechselt werden.Claim 8 goes beyond claim 6, the fact that with the seal omitted and the need to generate a contact pressure on this seal, which very simple tool-free mounting of the shower head, for example. enabled by magnetic attraction. A magnetically attached showerhead could be removed very easily for cleaning purposes, or it could easily be changed as desired from a selection of variously designed compatible showerheads.

Patentanspruch 9 beschreibt die Möglichkeit, den Duschkopf direkt an einer Wand oder Decke zu befestigen. Mit einer solchen Gestaltung sind z.B. in die Decke eingelassene oder massive, von einer Wand aus überkragende Installationen möglich.Claim 9 describes the possibility to attach the shower head directly to a wall or ceiling. With such a design, for example, embedded in the ceiling or massive, overhanging from a wall installations are possible.

Fig. 1 zeigt eine Ausführung, deren äußere Form runden Regen-Duschköpfen nach dem Stand der Technik nahe kommt, dabei jedoch auf dem beschriebenen neuen Funktionsprinzip beruht. Ein eine Abtropffläche 5 aufweisender Teil 1 des Duschkopfes ist hier beispielhaft als bikonvexe Scheibe ausgeführt, welche an einem senkrecht von der Decke nach unten führenden Rohr befestigt ist. Das Rohr stellt einen Wasserzulauf 2 dar. Wasser 3 fließt aus dem Rohrende heraus auf eine obere Fläche 4 der Scheibe 1, wo es sich verteilt. Für eine gleichmäßige Verteilung ist es hilfreich, wenn das Wasser mit geringer Geschwindigkeit turbulenzarm und in alle Richtungen gleichmäßig austreten kann. Die Verteilerfläche 4 kann mit weitgehend beliebiger Topographie gestaltet werden mit der Einschränkung, dass konkave Stellen, aus denen Wasser nach Beendigung eines Duschvorgangs nicht abfließen kann, weniger zweckmäßig sind. Einfache und für eine gleichmäßige Verteilung des Wassers wirksame Topographien sind flach oder konvex. Von der Verteilerfläche 4 ausgehend fließt das Wasser 3 unter Ausnutzung seiner Adhäsionskräfte um den Rand der Scheibe 1 herum auf die Abtropffläche 5 des Duschkopfes. Die Fläche 5 ist insgesamt konvex gestaltet, so dass das Wasser 3 vom Rand der Fläche 5 aus zum tiefsten Punkt der Fläche 5 läuft. Auf dem Weg dahin stehen in diesem Beispiel mehrere auf der Fläche 5 verteilt angeordnete Elemente einer entsprechenden Abtropfstruktur 6. Diese sind geometrisch ähnlich den Stalaktiten einer Tropfsteinhöhle ausgeführt und bewirken zusammen das verteilte Abtropfen des Wassers 3, so dass sich ein regenartiger Duschstrahl ergibt. Die genaue Form und Größe der Elemente der Abtropfstruktur 6 beeinflusst den lokalen Wasserabfluss und die Tropfenbildung. Alternativ zur stalaktitenähnlichen Struktur 6 sind im Wesentlichen nadelfömige, zylindrische, rippenförmige oder gänzlich unregelmäßige Strukturen denkbar. Alternativ zu solchen geometrischen Abtropfstrukturen kann auch mit lokal hydrophob gestalteten Flächen ein verteiltes Abtropfen erzielt werden. Fig. 1 shows an embodiment whose outer shape comes close to round rain showerheads according to the prior art, but based on the new functional principle described. A part 1 of the shower head having a draining surface 5 is here by way of example designed as a biconvex disk, which is fastened to a pipe which leads vertically downwards from the ceiling. The tube represents a water inlet 2. Water 3 flows out of the tube end onto an upper surface 4 of the disc 1, where it is distributed. For even distribution, it is helpful if the water is low-turbulence and can escape evenly in all directions. The distributor surface 4 can be designed with a largely arbitrary topography, with the restriction that concave points from which water can not flow off after the completion of a showering process are less expedient. Simple and effective for a uniform distribution of water topographies are flat or convex. Starting from the distributor surface 4, the water 3 flows, taking advantage of its adhesive forces, around the edge of the pane 1 onto the draining surface 5 of the shower head. The surface 5 is designed to be convex overall, so that the water 3 runs from the edge of the surface 5 to the lowest point of the surface 5. On the way there are in this example a plurality of distributed on the surface 5 arranged elements of a corresponding Abtropfstruktur 6. These are geometrically similar to the stalactites of a stalactite cave and together cause the distributed dripping of the water 3, so that a rain-like shower jet results. The exact shape and size of the elements of the drip structure 6 influences the local water drainage and the dripping. As an alternative to the stalactite-like structure 6, essentially needle-shaped, cylindrical, rib-shaped or wholly irregular structures are conceivable. As an alternative to such geometric dripping structures, a distributed dripping can also be achieved with surfaces having a locally hydrophobic design.

Fig. 2 zeigt Elemente einer auf der Verteilerfläche 4 angeordneten Verteilerstruktur 7. Mit solchen Strukturen kann die Verteilung des Wassers 3 auf der Verteilerfläche 4 gezielt beeinflusst werden. Dadurch können z.B. Unregelmäßigkeiten oder Turbulenzen ausgeglichen werden, die sich beim Auslaufen des Wassers 3 aus dem Wasserzulauf 2 ergeben. Fig. 2 shows elements of a distributor structure arranged on the distributor surface 4. With such structures, the distribution of the water 3 on the distributor surface 4 can be influenced in a targeted manner. As a result, for example, irregularities or turbulence can be compensated, resulting in the leakage of the water 3 from the water inlet 2.

Fig. 3 zeigt beispielhaft eine Variante mit einer in die Verteilerfläche 4 integrierten Lichtquelle 8. Wie gezeigt eingebaut, wird die Lichtquelle 8 vom Wasser überflossen. Durch Unregelmäßigkeiten auf der Oberfläche des Wasserfilms wird das Licht dynamisch gebrochen sowie gestreut und erzeugt auf den angestrahlten Flächen Kaustiken und andere Lichteffekte, die denen eines Schwimmbades mit Unterwasserbeleuchtung ähneln. Der Begriff Lichtquelle bezieht sich hierbei auf den Ort, an dem die Lichtstrahlen austreten. Dieser kann mit dem Ort, an dem das Licht erzeugt wird, identisch sein, es ist jedoch auch denkbar, die Lichterzeugung an anderer Stelle vorzusehen und das Licht per Lichtleiter zum gewünschten Ort des Lichtaustritts zu leiten. Darüber hinaus ist denkbar, den gesamten Duschkopf 1 aus transparentem Material auszuführen und ihn mit Hilfe einer Lichtquelle in Gänze zum Leuchtobjekt zu machen. Fig. 3 shows an example of a variant with an integrated into the distribution surface 4 light source 8. As shown installed, the light source 8 is overflowed by water. Irregularities on the surface of the water film dynamically refract and scatter the light, creating caustics and other lighting effects similar to those of a swimming pool with underwater lighting on the illuminated surfaces. The term light source refers to the place where the light rays exit. This can be identical to the location where the light is generated, but it is also conceivable to provide the light generation elsewhere and to direct the light via the light guide to the desired location of the light exit. In addition, it is conceivable to carry out the entire shower head 1 made of transparent material and to make it with the help of a light source entirely to the luminous object.

Fig. 4 zeigt eine andere mögliche Ausführung des Duschkopfes. Der Duschkopf 1 mit der Abtropffläche 5 ist hierbei beispielhaft an einer Wand 9 befestigt gezeigt. Ebenso denkbar ist es, den Duschkopf 1 an einer Decke zu befestigen, ihn in diese einzulassen, oder sogar einen Teil der Decke selbst als Abtropffläche 5 auszuführen. In der gezeigten Ausführung wird der Wasserzulauf 2 nicht über ein separates Rohr bereitgestellt, sondern ist im Duschkopf 1 selbst vorgesehen. Fig. 4 shows another possible embodiment of the shower head. The shower head 1 with the draining surface 5 is shown here attached by way of example to a wall 9. It is also conceivable to attach the shower head 1 to a ceiling, to let him into this, or even perform a part of the ceiling itself as a drainer 5. In the embodiment shown, the water inlet 2 is not provided via a separate tube, but is provided in the shower head 1 itself.

Fig. 5 schließlich zeigt eine Gestaltung des Duschkopfes 1, bei der durch Veränderung eines Volumenstroms Q des Wasserflusses 3 alternativ zu einem von der Abtropfstruktur 6 ausgehenden Regenstrahl ein Schwallstrahl 10 erzeugt werden kann. Dazu tritt das Wasser 3 aus einer Schlitzdüse 11 aus, von der es unter Ausnutzung seiner Adhäsion auf die Abtropffläche 5 weiterläuft, wenn der Volumenstrom Q einen bestimmten, vorgegebenen Schwellwert Qkrit unterschreitet. Wird der Schwellwert überschritten, reißt die Adhäsion am Übergang zwischen Schlitzdüse 11 und Abtropffläche 5 ab, so dass sich das Wasser als Schwallstrahl 10 direkt auf die duschende Person ergießt. Fig. 5 Finally, shows a design of the shower head 1, in which by changing a volume flow Q of the water flow 3 alternatively to a outgoing from the drip structure 6 rain jet, a surge jet 10 can be generated. For this purpose, the water 3 exits from a slot nozzle 11, from which it continues to exploit its adhesion to the draining surface 5, when the volume flow Q falls below a certain, predetermined threshold value Q crit . If the threshold is exceeded, the adhesion at the transition between the slot nozzle 11 and draining surface 5 ruptures, so that the water pours as a flood jet 10 directly to the showering person.
