Abstract

A new shower head is intended for handheld and/or fixed shower fitting. Connected to the water supply, its casing (12) forms a chamber with a base section (2). The base section has an outer ring (3) in rubbery, elastic material with grooves (33) to produce the water jets. The ring rests by its outer casing in a reception bore (16). In this novel design, the ring and a collar (30) project downstream beyond the base section which acts as a carrier plate. By scraping or working the collar, limescale deposits in the grooves can be removed. Preferably the base section is plastic, especially polypropylene. The ring element (3) is a thermoplastic elastomer, especially Santoprene (RTM), which is injected onto the base section,

Description

Die Erfindung betrifft einen Brausekopf für eine Handund/oder Stationärbrause mit einem an die Wasserzufuhr anschließbaren, wenigstens eine Wasserkammer bildenden Gehäuse und einem Bodenteil, wobei der Bodenteil wenigstens an einem Außenmantelbereich ein aus gummielastischem Werkstoff hergestelltes Ringelement hat, welches am Außenumfang eine Vielzahl von Nuten für die Erzeugung von Brausestrahlen aufweist, wobei das Ringelement mit wenigstens einem Teil seines Außenmantels an einer Aufnahmebohrung anliegt.The invention relates to a shower head for a hand and / or Stationary shower with a water supply connectable, forming at least one water chamber Housing and a bottom part, the bottom part at least on an outer jacket area made of elastic Material produced ring element, which a variety of grooves on the outer circumference for production of shower jets, the ring element with at least part of its outer jacket on one Location hole is present.

Ein derartiger Brausekopf ist beispielsweise aus der US-Patentschrift 3,826,429 bekannt. Bei Brauseköpfen kann es zu Kalkablagerungen im Bereich der brausestrahlbildenden Nuten oder Öffnungen kommen, die die Brausestrahlbildung beeinträchtigen. Diese Kalkablagerungen bzw. Kalkverkrustungen in den Nuten oder Öffnungen werden hauptsächlich dadurch verursacht, daß der am Austrittsbereich einer Öffnung haftende Wassertropfen während der Nichtbenutzung der Brause eintrocknet. Die Kalkkristalle lagern sich dabei jeweils am Austrittsende der Öffnung oder Nut ab und härten, je nach Trocknungszeit, mehr oder weniger stark aus. Durch ein häufiges Wiederholen dieses Eintrocknungsvorganges, wie es nach jedem Duschen am Brausekopf auftritt, kann es zu Störungen bei der Brausestrahlbildung kommen bzw. auch zu einem völligen Verschluß der Nuten oder Öffnungen für die Erzeugung der einzelnen Brausestrahlen führen. Obwohl bei dem Brausekopf nach der US-Patentschrift 3,826,429 das Ringelement an dem aus starrem Werkstoff hergestellten Bodenteil bereits aus einem gummielastischen Werkstoff hergestellt ist, kann es hierbei problematisch sein, die unerwünschten und störenden Kalkverkrustungen zu entfernen.Such a shower head is for example from the U.S. Patent 3,826,429 is known. With shower heads there may be limescale deposits in the area of the shower jet Grooves or openings come that the Affect shower jet formation. These limescale deposits or lime incrustations in the grooves or openings are mainly caused by the fact that the Drops of water adhering to an opening dries up when the shower is not in use. The Lime crystals are deposited at the exit end the opening or groove and harden, depending on Drying time, more or less strong. Through a frequent repetition of this drying process, such as it occurs on the shower head after every shower, it can disturbances in the formation of the spray jet or also for a complete closure of the grooves or openings lead to the generation of the individual shower jets. Although with the shower head according to the US patent 3,826,429 the ring element on the rigid Base part made of one material rubber-elastic material is made, it can problematic here are the unwanted and disruptive Remove scale deposits.

Der Erfindung liegt deshalb die Aufgabe zugrunde, den im Oberbegriff des Anspruchs 1 angegebenen Brausekopf zu verbessern, so daß die sich in den Nuten des Brausekopfes bildenden Verkrustungen relativ leicht vom Brausebenutzer entfernt werden können.The invention is therefore based on the object specified in the preamble of claim 1 shower head to improve so that it is in the grooves of the shower head forming incrustations relatively easily by the shower user can be removed.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Ringelement mit einem Kragen stromabwärts über den als Trägerplatte wirkenden Bodenteil vorsteht, so daß durch ein Abstreichen oder Walken des Kragens Kalkabscheidungen in den Nuten entfernbar sind. This object is achieved in that the ring element with a collar downstream over the protrudes as a base plate acting so that by wiping or flexing the collar of lime deposits are removable in the grooves.

Weitere Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 18 angegeben.
Mit den vorgeschlagenen Maßnahmen wird mit einfachen Mitteln eine Entfernung der sich im wesentlichen am Austrittsende der als Strahlbildner wirkenden Nuten - da in erheblichem Maße nur im Bereich der Umgebungsluft ein Eintrocknen des Brausewassers möglich ist - entstehenden Kalkverkrustungen ermöglicht. Das erfindungsgemäße Ringelement kann sowohl an einem ortsfest im Gehäuse des Brausekopfes angeordneten Bodenteils angeordnet werden als auch an einem Bodenteil, welches axial zum Gehäuse des Brausekopfes bewegbar ist, um beispielsweise das Strahlbild des Brausekopfes zu verändern und/oder den Querschnitt der einzelnen Brausestrahlen zu verändern, so daß beispielsweise unterschiedlich harte Brausestrahlen erzeugt werden können.
Der mit dem Ringelement zusammenwirkende Bohrungsteil des Brausekopfes kann hierbei ebenfalls mit einem gummielastischen Werkstoff ausgekleidet sein.
Auch kann der Bodenteil insgesamt aus einem gummielastischen Werkstoff hergestellt werden, wobei dann der Tragbereich des Bodenteils - um die erforderliche Starrheit aufzuweisen - entsprechend dickwandig ausgebildet ist und/oder aus starrem Werkstoff, wie etwa Metall, hergestellte Tragkörper in dem Bodenteil vorgesehen (einvulkanisiert)werden.Further refinements of the invention are specified in claims 2 to 18.
With the proposed measures, removal of the limescale deposits which occur essentially at the outlet end of the grooves acting as jet formers is made possible with simple means, since drying of the shower water is only possible to a considerable extent in the area of the ambient air. The ring element according to the invention can be arranged both on a fixed base part arranged in the housing of the shower head and on a base part which can be moved axially to the housing of the shower head, for example in order to change the spray pattern of the shower head and / or to change the cross section of the individual shower jets, so that, for example, shower jets of different hardness can be generated.
The bore part of the shower head which interacts with the ring element can also be lined with a rubber-elastic material.
The base part can also be made entirely of a rubber-elastic material, in which case the supporting area of the base part - in order to have the required rigidity - is correspondingly thick-walled and / or support bodies made of rigid material, such as metal, are provided (vulcanized) in the base part ,

Bei der Position des Hohlkolbens 14 in der linken Bildhälfte gelangt das durch die Radialöffnungen 131 in den Hohlzylinder 13 einströmende Wasser über die Axialschlitze 1410 in einen Ringraum oberhalb des Bodenteils 2 und von hier in die einzelnen, über den Außenmantel des Ringelements 3 verteilten Nuten 33 und wird hier als Kranz von einzelnen Brausestrahlen abgegeben. Wird nun der Hohlkolben 14 von seiner in der linken Bildhälfte dargestellten Position durch eine Schraubbewegung mit dem Drehring 15 abgesenkt, so wird im gleichen Maße auch der Bodenteil 2 mit dem Ringelement 3 aus der Bohrung 16 des Drehrings 15 herausgeschoben. Hierdurch wird der Austrittsquerschnitt der Nuten 33 vergrößert, da die Grundfläche 310 gegen die Mittelachse 10 geneigt ist, so daß dadurch die Austrittsgeschwindigkeit der einzelnen Brausestrahlen entsprechend verringert wird und das Strahlbild der Brause insgesamt weicher ausfällt. Wird dagegen der Hohlkolben 14 an den Radialöffnungen 131 vorbeigeführt, so wird die Wasserzufuhr zu den Nuten 33 abgesperrt und das zufließende Wasser allein über die zentrale Düse 210 abgegeben.During the showering process, the shower water reaches the water chamber 12 via the ball head 11 in accordance with the arrows 100. Depending on the axial position of the hollow piston 14, the water flowing through the radial openings 131 into the hollow cylinder 13 either reaches the grooves 33 or the hollow piston 14, such as it is shown in the right half of Figure 1, and from here via the nozzle formation in the screw 21 as a single, bundled emerging massage jet to the outside.
When the hollow piston 14 is in the left half of the figure, the water flowing through the radial openings 131 into the hollow cylinder 13 passes through the axial slots 1410 into an annular space above the base part 2 and from here into the individual grooves 33 and distributed over the outer jacket of the ring element 3 is given here as a wreath of individual shower jets. If the hollow piston 14 is now lowered from its position shown in the left half of the figure by a screwing movement with the rotating ring 15, the base part 2 with the ring element 3 is also pushed out of the bore 16 of the rotating ring 15 to the same extent. As a result, the outlet cross section of the grooves 33 is enlarged, since the base area 310 is inclined towards the central axis 10, so that the exit velocity of the individual shower jets is correspondingly reduced and the spray pattern of the shower as a whole is softer. If, on the other hand, the hollow piston 14 is guided past the radial openings 131, the water supply to the grooves 33 is shut off and the inflowing water is discharged solely via the central nozzle 210.

In den einen relativ kleinen Querschnitt aufweisenden Nuten 33 und dem darüberliegenden Ringraum verbleibt in der Regel das Restbrausewasser, wenn die Brause abgestellt wird. Hierbei verdampft das im Endbereich des von der Nut 33 gebildeten Düsenkanals befindliche Wasser an der Umgebungsluft, so daß sich hier Kalk abscheiden kann, wobei gleichzeitig das verdampfte Wasser aus dem stromaufwärts gelegenen Düsenkanal und dem Ringraum aufgefüllt wird. Mit Hilfe des vorstehenden Kragens 30 kann nun der Benutzer in dem Falle, daß sich störende Kalkverkrustungen am Austrittsende aufgebaut haben, durch Abstreichen oder Walken des Kragens 30 mit der Hand diese Verkrustungen absprengen, so daß beim nächsten Duschvorgang die Nuten 33 störungsfreie Brausestrahlen abgeben können.In those with a relatively small cross-section Grooves 33 and the overlying annulus remains in usually the remaining shower water when the shower is turned off becomes. This evaporates in the end area of the water located by the groove 33 formed nozzle channel in the ambient air, so that lime deposits here can, while the evaporated water from the upstream nozzle channel and the Annulus is filled. With the help of the above Collar 30 can now the user in the event that annoying lime incrustations built up at the outlet end have, by wiping or flexing the collar 30 with blow off these incrustations by hand, so that when the next showering process the grooves 33 trouble-free shower jets can deliver.

Bei dem in den Figuren 2 bis 7 angegebenen Ausführungsbeispiel ist das Ringelement 3 mit vier verschieden geneigten Nuten 31,32,33,34 ausgestattet, die sich periodisch auf dem Außenmantel des Ringelements 3 wiederholen, wie es insbesondere aus Figur 3 der Zeichnung zu entnehmen ist. Die Nute 31 weist dabei eine Tiefe 3102 von 0,45 mm auf und ist mit ihrer Grundfläche 310 parallel zur Mittelachse 10 angeordnet. Die Nute 32 ist mit der Grundfläche 310 um 5° zur Mittelachse 10 geneigt ausgebildet, wie es insbesondere aus Figur 4 der Zeichnung zu entnehmen ist. Die Grundfläche 310 der Nute 33 ist mit einem Winkel von 10° gegen die Mittelachse 10 geneigt angeordnet, wie es aus Figur 5 der Zeichnung zu entnehmen ist. Die Nute 34 ist schließlich mit der Grundfläche 310 um 15° gegen die Mittelachse 10 geneigt angeordnet, wie es aus Figur 6 zu entnehmen ist. Durch die unterschiedliche Neigung der Grundfläche 310 der Nuten 31,32,33,34 kann ein gefächertes Brausebild erzeugt werden. Um ein günstiges Abstreifen oder Walken des Kragens 30 zu gewährleisten, ist hierbei die kegelförmige Verjüngung der Innenwandung 303 des Kragens 30 entsprechend gestuft ausgebildet, wie es insbesondere aus Figur 7 der Zeichnung zu entnehmen ist. Als vorteilhaft hat sich hierbei eine Neigung der Innenwandung 303 bei der Nute 31 von 15°, bei der Nute 32 von 20°, bei der Nute 33 von 25° und bei der Nute 34 von 30° erwiesen. Die Nuten 31,32,33,34 weisen dabei die gleiche Breite 3101 von 0,9 mm auf. Die kleinste Tiefe 3102 bei den Nuten 31,32,33,34 beträgt 0,45 mm.In the embodiment shown in Figures 2 to 7 is the ring element 3 with four different inclinations Grooves 31,32,33,34 equipped, which periodically repeat on the outer surface of the ring element 3, as is particularly the case in FIG. 3 of the drawing can be seen. The groove 31 has a depth 3102 of 0.45 mm and is parallel with its base area 310 arranged to the central axis 10. The groove is 32 with the base area 310 inclined by 5 ° to the central axis 10 trained, as it is in particular from Figure 4 Drawing can be seen. The base 310 of the groove 33 is at an angle of 10 ° to the central axis 10 arranged inclined, as shown in Figure 5 of the drawing can be seen. The groove 34 is finally with of the base area 310 inclined by 15 ° against the central axis 10 arranged, as can be seen from Figure 6. Due to the different inclination of the base area 310 the grooves 31,32,33,34 can have a fanned shower pattern be generated. For cheap stripping or walking to ensure the collar 30 is the conical Tapering the inner wall 303 of the collar 30 appropriately graduated, as it is in particular can be seen from Figure 7 of the drawing. As beneficial here has an inclination of the inner wall 303 for slot 31 of 15 °, for slot 32 of 20 °, proven at slot 33 of 25 ° and slot 34 of 30 °. The grooves 31,32,33,34 have the same Width 3101 from 0.9 mm. The smallest depth 3102 at the grooves 31,32,33,34 is 0,45 mm.

Das in den Figuren 8 bis 13 dargestellte Ausführungsbeispiel unterscheidet sich zu dem in den Figuren 2 bis 7 dargestellten Ausführungsbeispiel lediglich dadurch, daß der vorstehende Kragen 30 von einzelnen um die Nuten 31,32,33,34 ausgebildeten Vorsprüngen 302 gebildet wird, wie es insbesondere aus Figur 8 und 13 zu entnehmen ist. Mit den einzelnen Vorsprüngen 302 läßt sich besonders günstig ein Abstreifen und Walken zur Entfernung von Kalkverkrustungen erreichen.The embodiment shown in Figures 8 to 13 differs from that in Figures 2 to 7 embodiment shown only by that the protruding collar 30 of individual around the grooves 31,32,33,34 formed projections 302 as can be seen in particular from FIGS. 8 and 13 is. The individual projections 302 can be used stripping and milling for removal are particularly favorable of scale deposits.

Bei den drei Ausführungsbeispielen ist der Bodenteil 2 aus Kunststoff im Spritzgußverfahren hergestellt. Vorteilhaft kann hierbei der Kunststoff Polypropylen eingesetzt werden. Das Ringelement 3 ist dabei aus einem thermoplastischen Elastomer (TPE) an dem Bodenteil 2 als Verbundwerkstoff angespritzt worden. Hierbei hat sich das thermoplastische Elastomer "Santoprene" als günstig erwiesen.
Selbstverständlich kann aber auch das Ringelement 3 aus einem anderen geeigneten gummielastischen Werkstoff hergestellt sein und an der Mantelfläche des aus einem geeigneten Werkstoff hergestellten Bodenteils 2 anvulkanisiert oder angeklebt werden.
