Description

Die Erfindung betrifft eine Vorrichtung zum Zapfen einer Flüssigkeit, insbesondere von Trinkwasser, mit wenigstens einem Flüssigkeitszulauf, wenigstens einem dem Flüssigkeitszulauf zugeordneten Zapfauslass und wenigstens einem dem Zapfauslass zugeordneten Flüssigkeitsabfluss, wobei der Flüssigkeitszulauf, der Zapfauslass sowie der Flüssigkeitsabfluss über wenigstens ein Wegeventil miteinander verbunden sind, in dessen Ventilgehäuse wenigstens ein Steuerglied stellbeweglich gehalten ist.The invention relates to a device for tapping a liquid, in particular drinking water, with at least one liquid inlet, at least one Zapfauslass associated with the liquid inlet and at least one Zapfauslass the associated liquid drain, wherein the liquid inlet, the Zapfauslass and the liquid drain are connected via at least one directional control valve, in the valve housing at least one control member is held adjustable movable.

Bei bekannten Vorrichtungen wird der Flüssigkeitszulauf an eine Flüssigkeitsquelle, beispielsweise an ein Flüssigkeitsversorgungsnetz oder an einen Flüssigkeitsspeicher angeschlossen. Der Flüssigkeitsablauf wird hingegen an ein Abwassernetz oder an einen Abwassersammelbehälter angeschlossen. Um die Flüssigkeit vom Flüssigkeitszulauf an den Zapfauslass zu befördern, ist der Flüssigkeitsquelle regelmäßig ein Pumpwerk zugeordnet. Das Wegeventil dient in einer Spülstellung bevorzugt dazu, mit einem Zusatz, insbesondere mit einem Desinfektionsmittel versetzte Flüssigkeit oder erhitzte Flüssigkeit, von dem Flüssigkeitszulauf über den Zapfauslass direkt in den Flüssigkeitsabfluss einzuleiten. In einer Zapfstellung dient das Wegeventil bevorzugt dazu, eine gebrauchsfertige Flüssigkeit, beispielsweise Trink- oder Duschwasser, vom Flüssigkeitszulauf direkt durch den Zapfauslass hindurch in die Atmosphäre zu leiten. Eine gattungsgemäße Vorrichtung ist aus der deutschen Offenlegungsschrift DE 10 2004 023 968 A1 bekannt. Die in dieser Schrift beschriebene Tafelwasseranlage ist jedoch nicht für den Einsatz an handelsverfügbaren sanitären Einrichtungen, wie Wasch- und Spülbecken, Badewannen- oder Duschkabinen geeignet, da die Unterbringung dieser Tafelwasseranlage einen Bauraum erfordert, der bei handelsüblichen sanitären Einrichtungen nicht oder nur mit erheblichem Aufwand verfügbar ist.In known devices, the liquid feed is connected to a liquid source, for example to a liquid supply network or to a liquid storage. The liquid drain, however, is connected to a sewage network or to a sewage collection tank. In order to convey the liquid from the liquid inlet to the dispensing outlet, the liquid source is regularly assigned to a pumping station. In a scavenging position, the directional control valve preferably serves to introduce liquid or heated liquid added with an additive, in particular a disinfectant, directly into the liquid outflow from the liquid feed via the dispensing outlet. In a dispensing position, the directional control valve preferably serves to direct a ready-to-use liquid, for example drinking or shower water, from the liquid inlet directly through the dispensing outlet into the atmosphere. A generic device is known from the German patent application DE 10 2004 023 968 A1 known. However, the table water system described in this document is not suitable for use on commercially available sanitary facilities, such as washing and sinks, bathtubs or shower cabins, since the accommodation of this Bottled water system requires a space that is not available or only with considerable effort in commercial sanitary facilities.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Gattung aufzuzeigen, die insbesondere für den Einsatz an handelsverfügbaren sanitären Einrichtungen geeignet ist.The invention is therefore based on the object to show a device of the type mentioned, which is particularly suitable for use on commercial sanitary facilities.

Diese Aufgabe ist erfindungsgemäß mit einer Vorrichtung mit den Merkmalen des Schutzanspruches 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved with a device with the features of the protection claim 1. Advantageous developments of the invention are specified in the subclaims.

Die erfindungsgemäße Vorrichtung zeichnet sich dadurch aus, dass der Zapfauslass an wenigstens einem Kolben ausgebildet ist, dass das Ventilgehäuse den Hubkolben hubbeweglich, jedoch drehfest aufnehmende Führungsflächen aufweist, dass das Ventilgehäuse das Steuerglied drehbeweglich aufnehmende Gleitflächen aufweist, dass der Hubkolben und das Steuerglied über wenigstens eine Kulissenführung zwangsbeweglich aneinander geführt sind, dass mit dem Steuerglied und dem Ventilgehäuse wenigstens ein dem Zapfauslass zugehöriger Drehschieberverschluss ausgebildet ist, und dass der Hubweg des Zapfauslasses durch den Drehschieberverschluss hindurchgeführt ist.The inventive device is characterized in that the dispensing outlet is formed on at least one piston, that the valve housing the reciprocating hub liftable, but rotatably receiving guide surfaces that the valve housing has the control member rotatably receiving sliding surfaces that the reciprocating piston and the control member via at least one Sliding guide are guided positively movable together, that with the control member and the valve housing at least one Zapfauslass associated rotary valve closure is formed, and that the stroke of the Zapfauslasses is passed through the rotary valve closure.

Die Kulissenführung fungiert als eine Art Getriebeteil, über deren Führungsflächen eine vorbestimmte Hubkraftkomponente einer in den Hubkolben eingeleiteten Hubkraft in ein vom Steuerglied aufzubringendes Drehmoment umgewandelt wird. In einer Richtung dient das Drehmoment dem Verdrehen des Steuergliedes in seine Zapfstellung hinein. In der Zapfstellung erlaubt der Drehschieberverschluss ein Hindurchtreten des vom Hubkolben bewegten Zapfauslasses aus dem Inneren des Ventilgehäuses durch die Gehäusewandungen des Ventilgehäuses hindurch in die Atmosphäre hinein. Dazu weist der Drehschieberverschluss in der Zapfstellung einander überlappende, vorzugsweise deckungsgleiche Durchlassöffnungen auf. In der jeweils anderen Richtung dient das Drehmoment dem Verdrehen des Steuergliedes in eine Spülstellung hinein. In der Spülstellung verhindert der Drehschieberverschluss, dass im Inneren des Ventilgehäuses aus dem Zapfauslass austretende Flüssigkeit durch die Gehäusewandungen des Ventilgehäuses hindurch in die Atmosphäre hinein gelangen kann. Dazu weist der Drehschieberverschluss in der Spülstellung einander gegenseitig verschließende Durchlassöffnungen auf. Die Kulissenführung dient somit der Verwirklichung komplexer Schaltvorgänge auf besonders engem Bauraum. Damit ist die erfindungsgemäße Vorrichtung vorteilhaft für den Einsatz an handelsverfügbaren sanitären Einrichtungen geeignet.The slide guide acts as a kind of transmission part, via the guide surfaces of which a predetermined lifting force component of a lifting force introduced into the lifting piston is converted into a torque to be applied by the control member. In one direction, the torque is used to rotate the control member into its tapping position. In the dispensing position, the rotary valve closure allows passage of the dispensing outlet moved by the reciprocating piston from the interior of the valve housing through the housing walls of the valve housing into the atmosphere. For this purpose, the rotary valve closure in the tapping position has overlapping, preferably congruent, passage openings. In the other direction, the torque is used to rotate the control member in a Rinse in. In the flushing position prevents the rotary valve closure that in the interior of the valve housing exiting liquid from the dispensing outlet can pass through the housing walls of the valve housing into the atmosphere inside. For this purpose, the rotary valve closure in the flushing position mutually occlusive passage openings. The slotted guide thus serves to achieve complex switching operations in a particularly compact space. Thus, the device according to the invention is advantageously suitable for use on commercially available sanitary facilities.

Nach einer ersten Weiterbildung der erfindungsgemäßen Vorrichtung weist der Zapfauslass eine Vielzahl, in Bezug auf die Drehachse des Steuergliedes, außermittig angeordnete Freistrahldüsen auf. Diese bilden gemeinsam einen Strahlregler aus, der der Vermischung der aus dem Zapfauslass austretenden Flüssigkeit mit der Umgebungsluft zu einem belüfteten, weichen und nicht spritzenden Mischstrahl dient. Es ist jedoch ebenso denkbar, dass der Zapfauslass lediglich eine einzige als Strahlregler oder Mischdüse fungierende Freistrahldüse aufweist.According to a first development of the device according to the invention, the dispensing outlet has a multiplicity, with respect to the axis of rotation of the control member, eccentrically arranged free-jet nozzles. These together form a jet regulator which serves to mix the liquid leaving the dispensing outlet with the ambient air to form a ventilated, soft and non-squirting mixed jet. However, it is also conceivable that the dispensing outlet has only a single acting as a jet regulator or mixing nozzle free jet.

Nach einer nächsten Weiterbildung der Erfindung weist die Kulissenführung wenigstens einen um die Drehachse des Steuergliedes herum verlaufenden schraubenförmigen Führungsabschnitt sowie wenigstens einen parallel zum Hubweg des Hubkolbens verlaufenden geradlinigen Führungsabschnitt auf. Der schraubenförmige Führungsabschnitt dient der Umwandlung der auf seine Führungsflächen wirkenden Hubkraftkomponente in das vom Steuerglied für seine Steuerbewegung aufzubringende Drehmoment und damit dem Öffnen und Schließen des Drehschieberverschlusses. Nach Beendigung der Steuerbewegung dient der geradlinige Führungsabschnitt entweder dem Hindurchführen des vom Hubkolben bewegten Zapfauslasses durch den zuvor geöffneten Drehschieberverschluss hindurch oder dem Herausziehen des vom Hubkolben bewegten Zapfauslasses aus dem noch geöffneten Drehschieberverschluss heraus. Selbstverständlich liegt es im Rahmen der Erfindung, die beiden Führungsabschnitte durch abgerundete Führungsverläufe derart miteinander zu verbinden, dass das Wegeventil eine weiche Schaltcharakteristik aufweist.According to a further development of the invention, the slide guide has at least one helical guide section extending around the axis of rotation of the control member and at least one rectilinear guide section extending parallel to the stroke of the reciprocating piston. The helical guide section serves to convert the lifting force component acting on its guide surfaces into the torque to be applied by the control member for its control movement, and thus the opening and closing of the rotary valve closure. After completion of the control movement of the rectilinear guide section is either the passage of the piston moved from the dispensing nozzle through the previously opened rotary valve closure through or pulling out of the reciprocating moving dispensing nozzle from the still open rotary valve closure. Of course, it is within the scope of the invention, the two guide sections by rounded guide courses connect to each other such that the directional control valve has a soft switching characteristic.

Um auf eine Ansteuerung des Wegeventils mittels separater Steuerleitungen verzichten zu können, stehen der Hubkolben und das Steuerglied über wenigstens einen dem Flüssigkeitszulauf zugeordneten Druckschalter miteinander in Wirkverbindung. Auf diese Weise fungiert die am Flüssigkeitszulauf anstehende Flüssigkeit als Arbeitsmittel für das Ansteuern des Wegeventils. Der Druckschalter ist im Rahmen dieser Erfindung dazu geeignet, das Wegeventil in Abhängigkeit des am Flüssigkeitszulauf anstehenden Flüssigkeitsdruckes zu schalten. Um zu verhindern, dass in einem Zwischenbereich liegende Drücke zum Flattern des Wegeventils führen, sind Vor- und Rückschaltpunkt des Wegeventils beabstandet zueinander angeordnet.In order to dispense with a control of the directional control valve by means of separate control lines, the reciprocating piston and the control member are at least one of the liquid supply associated pressure switch with each other in operative connection. In this way, the liquid present at the liquid inlet acts as a working medium for the control of the directional control valve. In the context of this invention, the pressure switch is suitable for switching the directional valve as a function of the fluid pressure present at the fluid inlet. In order to prevent lying in an intermediate region pressures cause the directional valve to flutter, the forward and reverse point of the directional control valve are spaced from each other.

Vorzugsweise weist der Druckschalter eine zwischen dem Hubkolben und dem Steuerglied angeordnete Rückstellfeder auf. Um den Vorschaltpunkt und den Rückschaltpunkt des Wegeventils mittels einer Hysterese beabstandet zueinander anzuordnen, kann die Rückstellfeder eine bistabile Federkennlinie aufweisen. Diese verhindert auf mechanisch einfache und zuverlässige Weise die Ausbildung instabiler Schaltzustände.Preferably, the pressure switch on a arranged between the piston and the control member return spring. To arrange the feed point and the return point of the directional control valve by means of a hysteresis spaced from each other, the return spring may have a bistable spring characteristic. This prevents the formation of unstable switching states in a mechanically simple and reliable manner.

Zum Desinfizieren der erfindungsgemäßen Vorrichtung kann der Flüssigkeitszulauf nach einer anderen Weiterbildung der Erfindung über wenigstens ein Absperrventil an einen Desinfektionsmittelzulauf angeschlossen sein. Dabei ist es für die Erfindung unerheblich, ob den Flüssigkeitszulauf und den Desinfektionsmittelzulauf miteinander verbindende Leitungsteile Bestandteil der erfindungsgemäßen Vorrichtung sind.For disinfecting the device according to the invention, the liquid feed can be connected according to another embodiment of the invention via at least one shut-off valve to a disinfectant feed. It is irrelevant for the invention, whether the liquid inlet and the disinfectant inlet interconnecting line parts are part of the device according to the invention.

Nach einer nächsten Weiterbildung der Erfindung ist mit dem Steuerglied und dem Ventilgehäuse wenigstens ein dem Flüssigkeitsabfluss zugeordneter Drehschieberverschluss ausgebildet. Dieser Drehverschluss ist, wie der dem Zapfauslass zugeordnete Drehschieberverschluss, ebenfalls über einander gegenseitig verschließende Durchlassöffnungen ausgebildet. In derAccording to a next development of the invention, at least one rotary slide valve closure associated with the fluid outlet is formed with the control member and the valve housing. This rotary closure is, like the rotary valve closure associated with the dispensing outlet, likewise formed via mutually closing passage openings. In the

Spülstellung erlaubt der dem Flüssigkeitsabfluss zugeordnete Drehschieberverschluss, dass im Inneren des Ventilgehäuses aus dem Zapfauslass austretende Flüssigkeit, vorzugsweise eine mit einem Desinfektionsmittel versetzte Flüssigkeit, durch die Gehäusewandungen des Ventilgehäuses hindurch gelangen und sicher über den Flüssigkeitsabfluss abgeführt werden kann. Im Bereich der Zapfstellung ist der dem Flüssigkeitsabfluss zugeordnete Drehschieberverschluss vorzugsweise verschlossen, so dass die Spülstellung und die Zapfstellung über die Führungsabschnitte der Kulissenführung zueinander beabstandet angeordnet sind.Flushing allows the liquid drainage associated rotary valve closure, that in the interior of the valve housing emerging from the dispensing outlet liquid, preferably a staggered with a disinfectant liquid, pass through the housing walls of the valve housing and can be safely discharged through the liquid drain. In the region of the dispensing position, the rotary slide valve closure assigned to the liquid outflow is preferably closed, so that the scavenging position and the dispensing position are arranged at a distance from one another via the guide sections of the slotted guide.
