Description

Die Erfindung betrifft ein sanitäres Wasserventil mit einem an dem Auslaufrohr des Wasserventils angebrachten, den Wasserstrahl bündelnden Auslaufteil.The invention relates to a sanitary water valve with a attached to the outlet pipe of the water valve, the water jet bundling outlet part.

Ein sanitäres Wasserventil mit den vorgenannten Merkmalen ist aus der DE 202 16 304 U1 bekannt, bei dem das Auslaufteil der Erzeugung eines weichen und nicht-spritzenden Wasserstrahls dienen soll. Hierzu ist das Auslaufteil als ein in das Auslaufrohr des Wasserventils eingesetztes Einsetzteil ausgebildet, welches in seinem inneren Strömungsweg angeordnete, geeignete Einbauten wie beispielsweise Siebe und dergleichen aufweist.A sanitary water valve with the above features is from the DE 202 16 304 U1 in which the outlet part is intended to produce a soft and non-squirting jet of water. For this purpose, the outlet part is designed as an inserted into the outlet pipe of the water valve insert part, which has arranged in its inner flow path, suitable internals such as screens and the like.

Wie weiterhin der DE 103 12 308 A1 zu entnehmen ist, werden die zugehörigen, mit einem Auslaufteil auszurüstenden Sanitärarmaturen vorwiegend aus Messinglegierungen hergestellt, wobei deren sichtbare Oberflächen zusätzlich verchromt sind. Das durch die Wasserventile strömende Wasser ist allerdings von den Messingoberflächen der als Gußkörper ausgebildeten Wasserventile umschlossen. Daraus hat die Fachwelt den Nachteil abgeleitet, daß aus den für die Herstellung der Wasserventile verwendeten Messinglegierungen Metallionen, insbesondere Kupferionen und Zinkionen, an das Wasser abgegeben werden. Soweit die Wasserventile vor ihrer Verchromung noch mit einer Beschichtung aus Nickel versehen werden, ist ein Einstreuen dieser Nickelbeschichtung in das Auslaufrohr hinein nicht zu vermeiden, so daß auch Nickelionen in das ausfließende Wasser gelangen können. Zur Vermeidung dieses als nachteilig angesehenen Effektes ist bereits vorschlagen worden, daß zumindest auf den bei einer Benutzung der Wasserventile mit Wasser in Kontakt tretenden inneren Oberflächen der Ventilbauteile mindestens teilweise eine Kupferoxidschicht ( DE 2007 055 446 A1 ) oder eine Kupfersulphitschicht ( DE 10 2006 054 761 ) aufgebracht wird.How continues the DE 103 12 308 A1 it can be seen, the associated, to be equipped with a spout part sanitary fittings are mainly made of brass alloys, with their visible surfaces are also chrome-plated. However, the water flowing through the water valves is enclosed by the brass surfaces of the water valves designed as a casting. From this, the experts have derived the disadvantage that metal ions, in particular copper ions and zinc ions, are released into the water from the brass alloys used for the production of the water valves. As far as the water valves are provided before their chrome plating with a coating of nickel, a scattering of this nickel coating in the outlet pipe is unavoidable, so that nickel ions can get into the effluent water. To avoid this as disadvantageous effect has already been proposed that at least on the case of using the water valves in contact with water in contact with the inner surfaces of the valve components at least partially a copper oxide ( DE 2007 055 446 A1 ) or a copper sulphite layer ( DE 10 2006 054 761 ) is applied.

Im Rahmen des Einsatzes derartiger Wasserventile in Bereichen, in denen Menschen mit einer eingeschränkten Widerstandskraft gegen bakteriologische Belastungen des Wassers mit dem aus den Wasserventilen abgezapften Wasser in Berührung kommen, also insbesondere in Krankenhäusern und anderen Pflegestationen, hat sich herausgestellt, daß es innerhalb des Wasserventils im Besonderen im Rahmen eines Abzapfens von warmem Wasser zur Bildung von Bakterienansammlungen in Form von sogenannten Legionellen kommt, die sich als gefährlich für den Gesundheitszustand der betroffenen Menschen herausgestellt haben.In the context of the use of such water valves in areas in which people come with a limited resistance to bacteriological contamination of the water in contact with the water tapped from the water valves, ie in particular in hospitals and other nursing stations, it has been found that it is within the water valve in the Specifically, as part of a tap of warm water for the formation of bacterial accumulations in the form of so-called Legionella comes, which have been found to be dangerous to the health of the affected people.

Der Erfindung liegt daher die Aufgabe zugrunde, ein sanitäres Wasserventil mit den eingangs genannten Merkmalen so einzurichten, daß eine Belastung des durch das Wasserventil fließenden Wassers mit Bakterien zumindest vermindert bzw. eingeschränkt ist.The invention is therefore based on the object to set up a sanitary water valve with the features mentioned so that a load of water flowing through the water valve with bacteria is at least reduced or limited.

Die Lösung dieser Aufgabe ergibt sich einschließlich vorteilhafter Ausgestaltungen und Weiterbildungen der Erfindung aus dem Inhalt der Patentansprüche, welche dieser Beschreibung nachgestellt sind.The solution to this problem arises, including advantageous refinements and developments of the invention from the content of the claims, which are adjusted to this description.

Die Erfindung sieht in ihrem Grundgedanken vor, daß das in seinem inneren Strömungsweg mit einem lichten Querschnitt ohne zusätzliche Einbauten ausgebildete Auslaufteil einen sich an den durch das Auslaufrohr gebildeten inneren Strömungsweg des Wassers anschließenden und sich bis zum Erreichen eines Auslaufabschnittes kegelförmig verengenden Einlaufabschnitt aufweist und daß die mit dem Wasser in Berührung kommenden Innenflächen des Auslaufteils mit einer Beschichtung aus einem antibakterielle Eigenschaften aufweisenden Material versehen sind.The invention provides in its basic idea that in its inner flow path formed with a clear cross-section without additional internals outlet part adjacent to the formed by the outlet pipe inner flow path of the water and conically narrowing until reaching an outlet section inlet section and that the in contact with the water coming inner surfaces of the outlet part are provided with a coating of antibacterial properties having material.

Die Erfindung beinhaltet die Erkenntnis, daß für eine eventuelle Belastung des Wassers mit Bakterien insbesondere die mit entsprechenden Einbauten versehenen Strahlregler bzw. Perlatoren als in das Auslaufrohr eines Wasserventils eingesetzte Einsetzteile verantwortlich sind, da sich einerseits Schmutzpartikel und andere, im Wasser enthaltene Bestandteile auf der Innenseite der vorzugsweise als Siebe ausgebildeten Einbauten der Einsetzteile absetzen und andererseits auch bei der Handhabung des Wasserventils zusätzlich von außen Belastungen eingetragen werden können. Zusätzlich verbleiben auch nach dem Schließen des Wasserventils Reste an Wasser im Bereich der Einbauten des Einsetzteils. Insbesondere bei mittleren Warmwasser-Temperaturen entsteht hierdurch ein Nährboden für eine davon ausgehende bakteriologische Belastung. Insofern besteht ein Aspekt der Erfindung darin, bei einem Auslaufteil auf die bisher verwendeten Einbauten zu verzichten. Um aber gleichwohl einen gerichteten Wasserstrahl ohne einen Spritzeffekt zu erzeugen, weist das erfindungsgemäße Auslaufteil einen an den Strömungsweg des Wasserventils anschließenden, sich kegelförmig, d. h. konisch verengenden Einlaufabschnitt auf. Hierzu hat sich herausgestellt, daß schon die Anordnung eines derartigen Einlaufabschnittes ausreichend ist, um einen benutzerfreundlichen Wasserstrahl zu erzeugen.The invention includes the recognition that for a possible contamination of the water with bacteria in particular provided with appropriate fittings aerator or aerators are responsible as inserted into the outlet pipe of a water valve inserts, as on the one hand dirt particles and other components contained in the water on the inside settle preferably designed as screens internals of the inserts and on the other hand also in the handling of the water valve can be entered from the outside loads. In addition, even after the water valve has been closed, residues of water remain in the area of the internals of the insert part. In particular, at medium hot water temperatures, this creates a breeding ground for a bacteriological load emanating therefrom. In this respect, one aspect of the invention is to dispense with an outlet part on the internals previously used. However, in order nevertheless to produce a directed water jet without a spraying effect, the outlet part according to the invention has a conical, adjoining the flow path of the water valve, d. H. conically narrowing inlet section. For this purpose, it has been found that even the arrangement of such inlet section is sufficient to produce a user-friendly water jet.

Weiterhin macht sich die Erfindung den wissenschaftlich an sich bekannten Effekt zunutze, wonach beispielsweise Kupferionen im Wasser enthaltene Bakterien abzutöten in der Lage sind, soweit auf den mit dem Wasser in Berührung kommenden Innenflächen des Auslaufteils beispielsweise eine Beschichtung aus Kupfer aufgebracht ist. Insofern sieht die Erfindung vor, die Innenflächen des Auslaufteils mit einer Beschichtung aus einem antibakterielle Eigenschaften aufweisenden Material zu versehen.Furthermore, the invention makes use of the scientifically known effect, according to which, for example, copper ions contained in the water are capable of killing, as far as on the coming into contact with the water inner surfaces of the outlet part, for example, a coating of copper is applied. In this respect, the invention provides to provide the inner surfaces of the outlet part with a coating of antibacterial properties having material.

Alternativ zu dem bereits genannten Kupfer kommen hier nach Ausführungsbeispielen der Erfindung insbesondere auch Silber bzw. silberhaltiges Material und Titan in Frage. Damit ist sichergestellt, daß beim Strömen des Wassers durch das Wasserventil bzw. dessen Auslaufteil eine eventuelle bakterielle Belastung des Wassers reduziert wird.As an alternative to the abovementioned copper, according to embodiments of the invention, silver and / or silver-containing material and titanium are also suitable here. This ensures that when the water flows through the water valve or its outlet part, a possible bacterial load on the water is reduced.

Gemäß alternativen Ausführungsbeispielen der Erfindung kann vorgesehen sein, daß der an den sich kegelförmig verengenden Einlaufabschnitt anschließende Auslaufabschnitt des Auslaufteils einen zylindrischen Querschnitt oder auch einen sich in Strömungsrichtung konisch erweiternden Querschnitt aufweist.According to alternative embodiments of the invention it can be provided that the adjoining the conically narrowing inlet section outlet portion of the outlet part has a cylindrical cross section or a conically widening in the flow direction cross section.

Es kann vorgesehen sein, daß das Auslaufteil in an sich bekannter Weise mit wenigstens einem Teil seiner Längserstreckung in das Auslaufrohr des Wasserventils einschraubbar ist.It can be provided that the outlet part is screwed in a conventional manner with at least part of its longitudinal extent in the outlet pipe of the water valve.

Soweit die Wasserventile auf ihren sichtbaren Außenflächen verchromt sind, kann auch vorgesehen sein, daß das Auslaufteil auf seiner äußeren Fläche verchromt ist, so daß das Auslaufteil ein gleiches Erscheinungsbild aufweist wie das Wasserventil, insbesondere dann, wenn das Auslaufteil mit einem Teil seiner Erstreckung aus dem Auslaufrohr des Wasserventils hervorsteht.As far as the water valves are chrome plated on their visible outer surfaces, it may also be provided that the outlet part is chromed on its outer surface, so that the outlet part has the same appearance as the water valve, especially if the outlet part with a part of its extension from the Outlet pipe of the water valve protrudes.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung wiedergegeben, welches nachstehend beschrieben ist. Es zeigen:

In das Ende eines Auslaufrohres 10 eines im Übrigen nicht weiter dargestellten sanitären Wasserventils ist ein hülsenförmiges Auslaufteil 11 mit einem sich über einen Teil seiner Längserstreckung ausgebildeten, nicht weiter dargestellten Gewinde eingeschraubt, wobei an dem Auslaufteil 11 eine im Endbereich des Auslaufrohres 10 zu liegen kommende Dichtung 20 angeordnet ist. Soweit das Auslaufrohr 10 einen inneren Wasserweg 16 aufweist, ist das Auslaufteil 11 mit einem an den inneren Wasserweg 16 des Auslaufrohres 10 angeschlossenen Einlaufabschnitt 12 ausgebildet, dessen Innenflächen 13 sich konisch verengen, so daß der Einlaufabschnitt in seinem Innenbereich einen sich in Richtung eines an den Einlaufabschnitt 12 anschließenden Auslaufabschnitts 14 verengenden Kegel aufweist. Der Auslaufabschnitt 14 des Auslaufteils 11 hat demgegenüber einen zylindrischen Querschnitt mit diesen begrenzenden Innenflächen 15.In the end of an outlet pipe 10 of a sanitary water valve, not shown, a sleeve-shaped outlet part 11 is screwed with a formed over part of its longitudinal extent, not shown thread, wherein at the outlet part 11 in the end region of the outlet pipe 10 coming seal 20 is arranged. As far as the outlet pipe 10 has an inner waterway 16, the outlet part 11 is formed with a connected to the inner waterway 16 of the outlet pipe 10 inlet portion 12, the inner surfaces 13 conically narrow, so that the inlet portion in its inner region in the direction of one of the Inflow section 12 subsequent outlet portion 14 has tapered cone. The outlet section 14 of the outlet part 11, in contrast, has a cylindrical cross-section with these bounding inner surfaces 15.

Das Auslaufteil 11 ist wie das sanitäre Wasserventil mit seinem Auslaufrohr 10 aus Messing hergestellt, wobei die Innenflächen 15 und 13 von Auslaufabschnitt 14 und Einlaufabschnitt 12 des Auslaufteils 11 mit einer Beschichtung aus einem antibakterielle Eigenschaften aufweisenden Material, beispielsweise Kupfer, versehen sind. Im Anschluss an das Aufbringen dieser Beschichtung auf die Innenflächen des Auslaufteils erfolgt noch eine Verchromung des Auslaufteils 11 auf seiner äußeren Oberfläche, wobei während dieses Verchromungsprozesses das Chrom sich nicht bzw. allenfalls geringfügig auf der Oberfläche der antibakteriellen Beschichtung ablagert. Somit ist dafür Sorge getragen, daß bei Benutzung des Wasserventils das dadurch strömende Wasser im Bereich des Auslaufteils ausschließlich mit der Beschichtung aus Kupfer als in diesem Fall gewählten, antibakterielle Eigenschaften aufweisenden Material in Berührung kommt.The outlet part 11 is like the sanitary water valve with its outlet pipe 10 made of brass, wherein the inner surfaces 15 and 13 of the outlet portion 14 and inlet portion 12 of the outlet part 11 with a coating of antibacterial properties having material, such as copper, are provided. Following the application of this coating on the inner surfaces of the outlet part is still a chromium plating of the outlet part 11 on its outer surface, wherein during this chrome plating process, the chromium does not or at most slightly deposited on the surface of the antibacterial coating. Thus, care is taken that when using the water valve, the water flowing through it in the region of the outlet part exclusively with the coating of copper than in this Case selected material having antibacterial properties comes into contact.
