Description
Die Erfindung betrifft einen Brausekopf mit einem an die Wasserzufuhr anschließbaren, wenigstens eine Was serkammer bildenden Gehäuse und einem Bodenteil, an dem elastische, schlauchartige Wasserstrahldüsen einstückig ausgebildet sind.The invention relates to a shower head with a connect the water supply, at least a what serkammer forming housing and a bottom part on which elastic, hose-like water jet nozzles in one piece are trained.
Ein derartiger Brausekopf, bei dem zur Entfernung von Kalkverkrustungen der Endbereich der Wasserstrahldüsen elastisch von Hand verformbar ist, ist aus der DE 39 43 062 A1 bekannt. Hierbei ist das gesamte Bodenteil aus einem Elastomer hergestellt, so daß es erforderlich ist, wenn Verformungen des gesamten Bodenteils durch den anstehenden Wasserdruck vermieden werden sollen, das Bodenteil relativ dickwandig auszubilden. Außerdem ist in dieser Druckschrift alternativ ein mehrteiliges Bodenteil vorgeschlagen, wobei dann die Wasserstrahldüsen in einer starren Bodenplatte einge legt oder eingeknöpft werden. Die Zusammenmontage der Einzelteile ist jedoch verhältnismäßig aufwendig. Auch kann hierbei nicht völlig ausgeschlossen werden, daß bei der Reinigung der vorstehenden Endbereiche der Was serstrahldüsen, diese in ihrer Position zur Bodenplatte verändert werden, so daß hieraus in unerwünschter Weise eine Änderung der Strahlrichtung und/oder gar eine Un dichtigkeit zwischen der Bodenplatte und den Wasser strahldüsen nicht völlig ausgeschlossen werden kann.Such a shower head, in which to remove Lime incrustations in the end area of the water jet nozzles is elastically deformable by hand, is from DE 39 43 062 A1 known. Here is the entire bottom part Made from an elastomer so it is required is when deformation of the entire bottom part occurs the upcoming water pressure should be avoided, form the bottom part relatively thick-walled. There is also an alternative in this document multi-part bottom part proposed, then the Water jet nozzles inserted in a rigid base plate puts or be buttoned up. The assembly of the However, items are relatively expensive. Also can not be completely excluded that when cleaning the above end portions of the What jet nozzles, these in their position to the base plate be changed so that this results in an undesirable manner a change in the beam direction and / or even an Un tightness between the bottom plate and the water jet nozzles cannot be completely ruled out.
Der Erfindung liegt die Aufgabe zugrunde, einen gat tungsgemäßen Brausekopf zu schaffen, bei dem eine dick wandige Ausbildung des Bodenteils nicht erforderlich ist, andererseits aber die schlauchartigen Wasseraus trittsöffnungen die erforderliche Elastizität beibehal ten können, sowie ein Verfahren zur Herstellung des Bo denteils vorzuschlagen.The invention has for its object a gat to create the appropriate shower head, in which a thick Wall formation of the bottom part is not necessary but on the other hand the hose-like water openings maintain the required elasticity ten can, as well as a method for producing the Bo partly to propose.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruchs 1 bzw. des Anspruchs 8 gelöst.This object is achieved with the features of claim 1 and claim 8 solved.
Weitere Ausgestaltungen der Erfindung sind in den An sprüchen 2 bis 7 angegeben.Further refinements of the invention are in the An say 2 to 7.

Das in der Zeichnung dargestellte Bodenteil ist für den Einsatz in einem Brausekopfgehäuse vorgesehen, wie es in der Patentanmeldung DE 41 16 932 A1 gezeigt ist. Das Bodenteil ist aus einem Kunststoffverbundmaterial her gestellt, wobei eine leicht gewölbte Trägerplatte 1 aus Polybutylenterephthalat (PBT) vorgesehen ist, an der an der stromaufwärts gelegenen Stirnwand eine etwa zylin derförmige Schürze 11 angeformt ist, an der ein in der Zeichnung nicht dargestellter Dichtring des Brausekopf gehäuses anliegt. Koaxial zur Schürze 11 ist an der Trägerplatte 1 an einem Rohransatz ein Gewinde 12 zur Befestigung am Gehäuse des in der Zeichnung ebenfalls nicht dargestellten Brausekopfes vorgesehen.The bottom part shown in the drawing is intended for use in a shower head housing, as shown in patent application DE 41 16 932 A1. The bottom part is made of a plastic composite material, wherein a slightly curved carrier plate 1 made of polybutylene terephthalate (PBT) is provided, on which an approximately zylin-shaped apron 11 is formed on the upstream end wall, on which a sealing ring of the shower head, not shown in the drawing housing is applied. Coaxially to the skirt 11 , a thread 12 is provided on the support plate 1 on a tube extension for attachment to the housing of the shower head, also not shown in the drawing.
In Durchtrittsöffnungen 13 sind Wasserstrahldüsen 2 aus Silikon zusammen mit an der stromaufwärts gelegenen Stirnseite der Trägerplatte 2 angeordneten, kreisring förmigen Scheiben 21 eingeformt. An der stromabwärts gelegenen Seite sind die Durchtrittsöffnungen 13 je weils mit einer Aussenkung 14 versehen, in die jeweils eine Wasserstrahldüse 2 mit einem außen umlaufenden Ringbund 22 eingreift, so daß in axialer Richtung jede Wasserstrahldüse 2 zusätzlich noch formschlüssig im Be reich der Durchtrittsöffnung 13 gehalten ist.In the openings 13 , water jet nozzles 2 made of silicone are formed together with annular disks 21 arranged on the upstream end face of the carrier plate 2 . On the downstream side, the passage openings 13 are each provided with a depression 14 , in each of which a water jet nozzle 2 engages with an outer circumferential ring collar 22 , so that each water jet nozzle 2 is additionally held in a positive manner in the area of the passage opening 13 in the axial direction .
Die Wasserstrahldüsen 2 haben, wie es insbesondere aus Fig. 1a zu entnehmen ist, jeweils einen in Strömungs richtung konisch verjüngt ausgebildeten Düsenkanal 23. Hierbei ist der Außenmantel, beginnend am Ringbund 22, stärker konisch verjüngt ausgebildet, so daß im Endbe reich die Wandstärke der Wasserstrahldüse 2 zunehmend verringert ist und störende Verkrustungen leicht durch ein Walken mit der Hand entfernbar sind.The water jet nozzles 2 , as can be seen in particular from FIG. 1 a, each have a nozzle channel 23 which is conically tapered in the direction of flow. Here, the outer jacket, starting at the collar 22 , tapered more strongly, so that in the end the wall thickness of the water jet nozzle 2 is increasingly reduced and annoying incrustations can be easily removed by hand flexing.
Das aus Kunststoffverbundmateril bestehende Bodenteil kann in folgender Weise hergestellt werden:The bottom part made of plastic composite material can be made in the following ways:
Zunächst wird die Trägerplatte 1 aus Polybutylentereph thalat (PBT) im Spritzgießverfahren hergestellt. Das Kunststoffmaterial kann hierbei mit einem Verstärkungs stoff, beispielsweise Glasfasern, gefüllt sein, so daß einerseits eine höhere Festigkeit erzielbar ist und an dererseits eine noch festere Verbindung mit dem Kunst stoffverbundmaterial Silikon erreicht werden kann. Da nach wird die Trägerplatte 1 in ein zweites Spritzgieß werkzeug eingebracht und hier die Wasserstrahldüsen 2 aus Silikon mit den kreisringförmigen Scheiben 21 an gespritzt. Hierbei findet eine Verbindung zwischen dem Silikon und dem PBT statt, so daß die Wasserstrahldüsen mit der Trägerplatte 1 unlösbar verbunden sind.First, the carrier plate 1 is made of polybutylene terephthalate (PBT) in an injection molding process. The plastic material can be filled with a reinforcing material, for example glass fibers, so that on the one hand a higher strength can be achieved and on the other hand an even stronger connection with the plastic composite material silicone can be achieved. Since after the carrier plate 1 is introduced into a second injection molding tool and here the water jet nozzles 2 are injected from silicone with the annular disks 21 . Here, a connection between the silicone and the PBT takes place, so that the water jet nozzles are permanently connected to the carrier plate 1 .
Alternativ kann auch als Kunststoffverbundmaterial die Materialpaarung Polypropylen (PP) und Thermoplastela stomer (TPE) eingesetzt werden. Auch in diesem Fall ist zunächst die Trägerplatte 1 aus Polypropylen mit den Durchtrittsöffnungen 13 herzustellen. Danach können, entsprechend dem vorstehend aufgeführten Ausführungs beispiel, die Wasserstrahldüsen 2 mit den ringförmigen Scheiben 21 aus Thermoplastelastomer angespritzt werden.Alternatively, the material combination of polypropylene (PP) and thermoplastic elastomer (TPE) can also be used as the plastic composite material. In this case too, the carrier plate 1 must first be made of polypropylene with the passage openings 13 . Then, according to the above-mentioned embodiment, for example, the water jet nozzles 2 are injected with the annular disks 21 made of thermoplastic elastomer.
