Definitions

  • the present invention relates to a drain arrangement according to the preamble of claim 1.
  • a drain arrangement has become known in which an overflow pipe is arranged above a valve and provides a bypass of the valve in the event of an excessively rising water level in a washbasin.
  • the valve can be raised in the vertical direction.
  • a disadvantage of the flow arrangement EP 0 342 723 is that due to the design of the drain arrangement, a comparatively large amount of space is required below the washbasin.
  • the invention is based on the object of specifying a drain arrangement which overcomes the disadvantages of the prior art.
  • the drain arrangement should be made more compact.
  • the drainage device should be easier to mount.
  • a drain arrangement for connection to a sanitary article comprises a drain pipe with a pipe inlet and a pipe outlet, one in a valve section of the drain pipe arranged valve with a sealing surface and a valve body, wherein the valve body can be moved with an actuating element from a closed position into an open position away from the sealing surface, and an overflow pipe, which extends from a first branch point in front of the valve, viewed in the flow direction of the water, to an in Flow direction of the water after the valve lying second branch point extends away from the drain pipe and so bypasses the valve.
  • the overflow pipe In the installed position, the overflow pipe extends essentially counter to the vertical direction upwards.
  • the valve body is at least partially mounted on an insert element.
  • the drain pipe has an insert receptacle, with the insert element being able to be inserted into the insert receptacle on the drain pipe.
  • the valve section In the installed position, the valve section extends in such a way that the direction of flow is essentially horizontal or inclined at an angle of no more than 20° to the horizontal, and that the sealing surface in the installed position is essentially vertical or inclined at an angle of no more than 20° is oriented to the vertical.
  • This design has the advantage that the drain pipe can be made more compact because the two branch points extend away from said valve section, which is horizontal.
  • the height of the installation space can be optimized because the sealing surface is vertical and the valve body is thus moved in a horizontal direction, at least at the beginning of its movement. The beginning of the movement is understood to mean that the valve body is set off from the sealing surface.
  • horizontal and vertical as used herein essentially refer to directions perpendicular and parallel to the plumb line, respectively.
  • substantially means that the vertical may be angled at a small angle of a few degrees to the plumb line, or that the horizontal may be angled at a small angle of a few degrees to the right angle to the plumb line.

  • the assembly process includes both assembly and disassembly. During disassembly, there is the advantage that because the valve body is mounted on the insert element, the valve body can be removed with the insert element from the insert receptacle. This allows easy access to the insert element. This is particularly advantageous when the valve body or parts attached to it have to be cleaned or replaced.

  • Another pipe that is connected to the sewage network can be connected to the pipe outlet.
  • the valve body is preferably a valve flap.
  • the sealing surface is preferably provided by the drain pipe or by the insert element, with the valve flap being able to be pivoted about a geometric pivot axis relative to the sealing surface.

  • the flow preferably fills the cross section of the valve section by a maximum of 50%.
  • the pivot axis or the bearing axis is preferably oriented horizontally in the installed position.
  • the pivot axis is located after the sealing surface, viewed in the direction of flow of the water.
  • the pivot axis is not in the water when the valve flap is in the closed position.
  • the valve flap preferably has a bent area which separates the actual flap at a distance to the bearing axis.

  • the circular-cylindrical design has the advantage that assembly and also the seal can be made very simple.
  • An orientation structure is preferably arranged between the insert element and the insert receptacle, which aligns the insert receptacle with the valve body mounted in the insert receptacle with respect to the sealing surface.
  • the arrangement of the orientation structure enables the insert element to be placed in the correct position in the insert receptacle. Correct positioning is advantageous because the valve body is then also arranged in the correct position.

Nachteilig an der Ablaufanordnung der EP 0 342 723 ist, dass aufgrund der Ausbildung der Ablaufanordnung einen vergleichsweise grossen Bauraum unterhalb des Waschtisches benötigt wird.From the EP 0 342 723 a drain arrangement has become known in which an overflow pipe is arranged above a valve and provides a bypass of the valve in the event of an excessively rising water level in a washbasin. The valve can be raised in the vertical direction. A disadvantage of the flow arrangement EP 0 342 723 is that due to the design of the drain arrangement, a comparatively large amount of space is required below the washbasin.

Darüber hinaus wird die Dichtung, welche das Ventil auf dem Ventilsitz abdichtet, bei offenem Ventil konstant mit Wasser überströmt, was bezüglich deren Lebensdauer nachteilig ist. Aus der US 2017/306598 und der WO 2007/086736 sind weiter Ablaufanordnungen bekannt geworden.In addition, the seal that seals the valve on the valve seat is constantly flooded with water when the valve is open, which is disadvantageous in terms of its service life. From the US2017/306598 and the WO 2007/086736 further sequence arrangements have become known.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Ausgehend von diesem Stand der Technik, liegt der Erfindung eine Aufgabe zugrunde, eine Ablaufanordnung anzugeben, welche die Nachteile des Standes der Technik überwindet. Insbesondere soll die Ablaufanordnung kompakter ausgebildet sein. Besonders bevorzugt soll die Ablaufvorrichtung besser montierbar sein.Proceeding from this prior art, the invention is based on the object of specifying a drain arrangement which overcomes the disadvantages of the prior art. In particular, the drain arrangement should be made more compact. Particularly preferably, the drainage device should be easier to mount.

Diese Aufgabe löst der Gegenstand vom Anspruch 1. Demgemäss umfasst eine Ablaufanordnung zum Anschluss an einen Sanitärartikel ein Ablaufrohr mit einem Rohreintritt und einem Rohraustritt, ein in einem Ventilabschnitt des Ablaufrohrs angeordnetes Ventil mit einer Dichtfläche und einem Ventilkörper, wobei der Ventilkörper mit einem Betätigungselement von einer Verschlusslage in eine Offenlage von der Dichtfläche weg bewegbar ist, und ein Überlaufrohr, welches sich von einer in Fliessrichtung des Wasser gesehen vor dem Ventil liegenden ersten Abzweigstelle zu einer in Fliessrichtung des Wassers nach dem Ventil liegenden zweiten Abzweigstelle vom Ablaufrohr weg erstreckt und so das Ventil überbrückt. Das Überlaufrohr erstreckt sich in Einbaulage im Wesentlichen entgegen der Lotrichtung nach oben. Der Ventilkörper ist mindestens teilweise an einem Einsatzelement gelagert. Das Ablaufrohr weist eine Einsatzaufnahme auf, wobei das Einsatzelement in die Einsatzaufnahme am Ablaufrohr einsetzbar ist.This object is solved by the subject matter of claim 1. Accordingly, a drain arrangement for connection to a sanitary article comprises a drain pipe with a pipe inlet and a pipe outlet, one in a valve section of the drain pipe arranged valve with a sealing surface and a valve body, wherein the valve body can be moved with an actuating element from a closed position into an open position away from the sealing surface, and an overflow pipe, which extends from a first branch point in front of the valve, viewed in the flow direction of the water, to an in Flow direction of the water after the valve lying second branch point extends away from the drain pipe and so bypasses the valve. In the installed position, the overflow pipe extends essentially counter to the vertical direction upwards. The valve body is at least partially mounted on an insert element. The drain pipe has an insert receptacle, with the insert element being able to be inserted into the insert receptacle on the drain pipe.

In Einbaulage verläuft der Ventilabschnitt derart, dass die Fliessrichtung im Wesentlichen in der Horizontalen oder in einem Winkel von maximal 20° winklig geneigt zur Horizontalen verläuft, und dass die Dichtfläche in Einbaulage im Wesentlichen in der Vertikalen oder in einem Winkel von maximal 20° winklig geneigt zur Vertikalen orientiert ist. Das heisst, dass in Einbaulage der Ventilabschnitt derart verläuft, dass die Fliessrichtung im Wesentlichen in der Horizontalen verläuft, und so die Absperrung durch das Ventil in dem horizontal liegenden Abschnitt liegt. Diese Ausbildung hat den Vorteil, dass das Ablaufrohr kompakter ausgebildet werden kann, weil die beiden Abzweigstellen sich vom besagten Ventilabschnitt, der in der Horizontalen liegt, weg erstrecken. Zudem kann der Bauraum in der Höhe optimiert werden, weil die Dichtungsfläche in der Vertikalen liegt und so der Ventilkörper, mindestens zu Beginn seiner Bewegung, in horizontaler Richtung bewegt wird. Unter dem Beginn der Bewegung wird das Absetzen des Ventilkörpers von der Dichtfläche verstanden.In the installed position, the valve section extends in such a way that the direction of flow is essentially horizontal or inclined at an angle of no more than 20° to the horizontal, and that the sealing surface in the installed position is essentially vertical or inclined at an angle of no more than 20° is oriented to the vertical. This means that in the installed position the valve section runs in such a way that the direction of flow runs essentially in the horizontal, so that the shut-off by the valve is in the horizontal section. This design has the advantage that the drain pipe can be made more compact because the two branch points extend away from said valve section, which is horizontal. In addition, the height of the installation space can be optimized because the sealing surface is vertical and the valve body is thus moved in a horizontal direction, at least at the beginning of its movement. The beginning of the movement is understood to mean that the valve body is set off from the sealing surface.

Die hierin verwendeten Ausdrucksweisen "Horizontale" und "Vertikale" beziehen sich im Wesentlichen auf Richtung rechtwinklig bzw. parallel zur Lotrichtung. In diesem Zusammenhang bedeutet "im wesentlichen", dass die Vertikale mit einem kleinen Winkel von einigen Grad winklig geneigt zur Lotrichtung stehen kann bzw. dass die Horizontale mit einem kleinen Winkel von einigen Grad winklig geneigt zum rechten Winkel zur Lotrichtung stehen kann.The terms "horizontal" and "vertical" as used herein essentially refer to directions perpendicular and parallel to the plumb line, respectively. In this context, "substantially" means that the vertical may be angled at a small angle of a few degrees to the plumb line, or that the horizontal may be angled at a small angle of a few degrees to the right angle to the plumb line.

Die Anordnung des Ventilkörpers an einem Einsatzelement hat den Vorteil, dass die Montage und Demontage des Ventilkörpers vereinfacht wird.The arrangement of the valve body on an insert element has the advantage that the Assembly and disassembly of the valve body is simplified.

Die Ausdrucksweise, "dass Ventilkörper mindestens teilweise an einem Einsatzelement gelagert ist", ist so zu verstehen, dass der Ventilkörper vollständig am Einsatzelement gelagert ist oder dass der Ventilkörper teilweise am Einsatzelement und teilweise an einem anderen Element der Anordnung gelagert ist.The expression "that the valve body is at least partially journaled on a cartridge" is to be understood as meaning that the valve body is journaled entirely on the cartridge or that the valve body is partially journalled on the cartridge and partially on another member of the assembly.

Die Lagerung ist dabei derart, dass sich der Ventilkörper relativ zur Dichtfläche bewegen kann.The storage is such that the valve body can move relative to the sealing surface.

Besonders bevorzugt ist die Lagerung des Ventilkörpers am Einsatzelement derart, dass der Ventilkörper bei einem Montagevorgang gemeinsam mit dem Einsatzelement in das Ablaufrohr einsetzbar ist. Der Montagevorgang umfasst sowohl die Montage als auch die Demontage. Bei der Demontage ergeht der Vorteil, dass aufgrund der Lagerung des Ventilkörpers am Einsatzelement der Ventilkörper mit dem Einsatzelement aus der Einsatzaufnahme entfernt werden kann. Hierdurch kann ein einfacher Zugriff auf das Einsatzelement geschaffen werden. Dies ist insbesondere dann von Vorteil, wenn der Ventilkörper oder daran befestigte Teile gereinigt oder ausgetauscht werden müssen.The mounting of the valve body on the insert element is particularly preferred in such a way that the valve body can be inserted into the drain pipe together with the insert element during an assembly process. The assembly process includes both assembly and disassembly. During disassembly, there is the advantage that because the valve body is mounted on the insert element, the valve body can be removed with the insert element from the insert receptacle. This allows easy access to the insert element. This is particularly advantageous when the valve body or parts attached to it have to be cleaned or replaced.

Dem Rohreintritt kann ein weiteres Rohr, das mit dem Sanitärartikel in Verbindung steht, angeschlossen werden. Dem Rohraustritt kann ein weiteres Rohr, das mit dem Abwassernetz in Verbindung steht, angeschlossen werden.Another pipe, which is connected to the sanitary item, can be connected to the pipe inlet. Another pipe that is connected to the sewage network can be connected to the pipe outlet.

Vorzugsweise ist der Ventilkörper eine Ventilklappe. Die Dichtfläche wird vorzugsweise durch das Ablaufrohr oder durch das Einsatzelement bereitgestellt, wobei sich die Ventilklappe relativ zur Dichtfläche um eine geometrische Schwenkachse verschwenken lässt. Die Ventilklappe ist mindestens teilweise an der Einsatzaufnahme gelagert und arbeitet mit der Dichtfläche, die am Ablaufrohr liegt, zusammen.The valve body is preferably a valve flap. The sealing surface is preferably provided by the drain pipe or by the insert element, with the valve flap being able to be pivoted about a geometric pivot axis relative to the sealing surface. The valve flapper is at least partially supported on the cartridge seat and cooperates with the sealing surface that bears on the drain tube.

Die Ausbildung des Ventilkörpers als Ventilklappe hat den Vorteil, dass eine einfache Ansteuerung und Betätigung des Ventilkörpers ermöglicht wird.The design of the valve body as a valve flap has the advantage that simple control and actuation of the valve body is made possible.

Die Ventilklappe ist an einer Lagerachse gelagert, welche um die geometrische Schwenkachse verschwenkbar ist. Die Lagerachse ist in einer Lagerstelle, insbesondere in einer Lageröffnung, am Einsatzelement und/oder in einer Lagerstelle, insbesondere in einer Lageröffnung, am Ablaufrohr verschwenkbar gelagert. Weiter weist die Lagerachse ein freies Ende auf, welches mit dem besagten Betätigungselement betätigbar ist.The valve flap is mounted on a bearing axis, which is about the geometric Pivot axis is pivotable. The bearing axis is pivotably mounted in a bearing point, in particular in a bearing opening, on the insert element and/or in a bearing point, in particular in a bearing opening, on the drain pipe. Furthermore, the bearing axle has a free end which can be actuated with said actuating element.

Wenn die Lagerstelle eine Lageröffnung ist, ist vorzugsweise eine Dichtung zwischen der Lagerachse und der Lageröffnung, insbesondere im stirnseitigen Bereich der Lageröffnung angeordnet. Mit der Dichtung lässt sich ein unbeabsichtigter Wasseraustritt aus dem Rohrabschnitt verhindern.If the bearing point is a bearing opening, a seal is preferably arranged between the bearing axis and the bearing opening, in particular in the front area of the bearing opening. The seal can be used to prevent unintentional water leakage from the pipe section.

Das freie Ende ist vorzugsweise Teil eines Hebelarms, welcher winklig geneigt, insbesondere rechtwinklig, von der Lagerachse wegsteht, wobei das Betätigungselement auf das freie Ende wirkt.The free end is preferably part of a lever arm which projects at an angle, in particular at right angles, from the bearing axis, the actuating element acting on the free end.

Das freie Ende liegt vorzugsweise ausserhalb des Ablaufrohrs und ist von ausserhalb des Ablaufrohrs betätigbar. Das heisst, dass das Betätigungselement ebenfalls ausserhalb des Rohrabschnittes angeordnet werden kann.The free end is preferably outside the drain pipe and can be actuated from outside the drain pipe. This means that the actuating element can also be arranged outside of the pipe section.

Vorzugsweise verläuft die geometrische Schwenkachse bzw. die Lagerachse in Einbaulage gesehen oberseitig im Ablaufrohr. Durch die Anordnung der Schwenkachse oberseitig ergeht der Vorteil, dass die Ventilklappe in der Offenlage nicht durch das Wasser, das den Ventilabschnitt durchströmt, überströmt wird. Hierdurch wird der Fluss des Wassers nicht durch die Ventilklappe gestört, was die Abflussleistung erhöht. Vorzugsweise füllt die Strömung in diesem Fall den Querschnitt des Ventilabschnittes zu maximal 50% aus.Preferably, the geometric pivot axis or the bearing axis, seen in the installed position, runs on the top side in the drain pipe. The arrangement of the pivot axis at the top has the advantage that the valve flap in the open position is not overflowed by the water flowing through the valve section. As a result, the flow of water is not disturbed by the valve flap, which increases the drainage capacity. In this case, the flow preferably fills the cross section of the valve section by a maximum of 50%.

Vorzugsweise ist die Schwenkachse bzw. die Lagerachse in Einbaulage in der Horizontalen orientiert.The pivot axis or the bearing axis is preferably oriented horizontally in the installed position.

Weiter ist es bevorzugt, dass die Schwenkachse in Fliessrichtung des Wassers gesehen nach der Dichtfläche liegt. Somit liegt die Schwenkachse nicht im Wasser, wenn sich die Ventilklappe in der Verschlusslage befindet. Diesbezüglich weist die Ventilklappe vorzugsweise einen Abkröpfbereich auf, welcher die eigentliche Klappe in einem Abstand zur Lagerachse hält.Furthermore, it is preferred that the pivot axis is located after the sealing surface, viewed in the direction of flow of the water. Thus, the pivot axis is not in the water when the valve flap is in the closed position. In this regard, the valve flap preferably has a bent area which separates the actual flap at a distance to the bearing axis.

Vorzugsweise liegt der Ventilkörper in der Offenlage im Wesentlichen oder wesentlich oberhalb der Mittelachse des Ventilabschnittes bzw. des Ablaufrohrs.In the open position, the valve body is preferably located essentially or substantially above the central axis of the valve section or the outlet pipe.

Vorzugsweise wirkt ein Rückstellelement auf den Ventilkörper, welches Rückstellelement den Ventilkörper in seiner Verschlusslage hält. Das Rückstellelement ist vorzugsweise am Einsatzelement gelagert. Vorzugsweise ist das Rückstellelement ausserhalb des wasserführenden Bereichs des Ablaufrohrs angeordnet. Das Rückstellelement ist besonders bevorzugt eine Blattfeder, welche auf die Lagerachse wirkt.A restoring element preferably acts on the valve body, which restoring element holds the valve body in its closed position. The restoring element is preferably mounted on the insert element. The restoring element is preferably arranged outside the water-carrying area of the drain pipe. The restoring element is particularly preferably a leaf spring which acts on the bearing axis.

Besonders bevorzugt kommt die Ventilklappe in ihrer Offenstellung in den Mündungsbereich der Abzweigstelle in den Ventilabschnitt zu liegen. Dabei verschliesst die Ventilklappe aber den Mündungsbereich nicht ganz, so dass im Falle einer Blockierung der Ventilklappe durch Fremdstoffe nach wie vor ein sicherer Überlauf durch das Überlaufrohr bereitgestellt werden kann.In its open position, the valve flap particularly preferably comes to lie in the opening region of the branch point in the valve section. In this case, however, the valve flap does not completely close the opening area, so that if the valve flap is blocked by foreign substances, a reliable overflow can still be provided through the overflow pipe.

Vorzugsweise weist das Einsatzelement einen kreiszylindrischen Lagerabschnitt auf und die Einsatzaufnahme weist einen kreiszylindrische Lageraufnahmeabschnitt auf, ein Dichtungselement ist zwischen Lagerabschnitt und Lageraufnahmeabschnitt angeordnet. Mit dem Dichtungselement wird eine Dichtung zwischen dem Einsatzelement und der Einsatzaufnahme geschaffen, so dass dort kein Wasser aus dem Ablaufrohr austreten kann. Die kreiszylinderische Ausbildung hat den Vorteil, dass die Montage und auch die Dichtung sehr einfach gestaltet werden kann.The insert element preferably has a circular-cylindrical bearing section and the insert receptacle has a circular-cylindrical bearing receiving section. A sealing element is arranged between the bearing section and the bearing receiving section. The sealing element creates a seal between the insert element and the insert receptacle, so that no water can escape from the drain pipe there. The circular-cylindrical design has the advantage that assembly and also the seal can be made very simple.

Vorzugsweise ist zwischen dem Einsatzelement und der Einsatzaufnahme eine Orientierungsstruktur angeordnet, welches die Einsatzaufnahme mit dem in der Einsatzaufnahme gelagerten Ventilkörper bezüglich der Dichtfläche ausrichtet. Durch die Anordnung der Orientierungsstruktur kann das Einsatzelement lagerichtig in der Einsatzaufnahme platziert werden. Die lagerichtige Positionierung ist vorteilhaft, weil der Ventilkörper dann ebenfalls lagerichtig angeordnet ist.An orientation structure is preferably arranged between the insert element and the insert receptacle, which aligns the insert receptacle with the valve body mounted in the insert receptacle with respect to the sealing surface. The arrangement of the orientation structure enables the insert element to be placed in the correct position in the insert receptacle. Correct positioning is advantageous because the valve body is then also arranged in the correct position.

Vorzugsweise umfasst das Einsatzelement ein Sicherungselement, welches nach erfolgtem Einsetzen des Einsatzelementes in die Einsatzaufnahme das Einsatzelement zum Ablaufrohr hin sichert. Das Sicherungselement ist vorzugsweise ein rein mechanisches Sicherungselement, welches keine Dichtungsfunktion aufweist.Preferably, the insert element comprises a securing element, which after the Insertion of the insert element into the insert receptacle secures the insert element to the drain pipe. The securing element is preferably a purely mechanical securing element which has no sealing function.

Vorzugsweise ist das Sicherungselement ein Deckel, welcher drehbar am Einsatzelement gelagert ist und welcher ein Gewinde aufweist, welches mit einem entsprechend ausgebildeten Gewinde am Ablaufrohr zusammenarbeitet. Vorzugsweise ist der Deckel lose am Einsatzelement drehbar gelagert. Besonders bevorzugt weist der Deckel eine umlaufende Nut auf, in welche ein Kamm des Einsatzelementes eingreift.The securing element is preferably a cover which is rotatably mounted on the insert element and which has a thread which cooperates with a correspondingly designed thread on the drain pipe. The cover is preferably rotatably mounted loosely on the insert element. The cover particularly preferably has a circumferential groove in which a comb of the insert element engages.

In einer anderen Variante ist das Sicherungselement am Einsatzelement angeformt und weist beispielsweise die Form eines Bajonettverschlusses auf.In another variant, the securing element is formed on the insert element and has, for example, the shape of a bayonet catch.

In einer ersten Ausführungsform mündet die Einsatzaufnahme zwischen der ersten Abzweigstelle und der zweiten Abzweigstelle in das Ablaufrohr. Die Einsatzaufnahme ist vorzugsweise derart orientiert, dass das Einsatzelement in Richtung einer quer zur Dichtfläche verlaufenden Einsetzrichtung in die Einsatzaufnahme einsetzbar ist. In Einbaulage verläuft die Einsetzrichtung vorzugsweise in Horizontaler Richtung. Die Einsatzrichtung ist bevorzugt parallel zur Orientierung der Schwenkachse.In a first embodiment, the insert receptacle opens into the drain pipe between the first branching point and the second branching point. The insert receptacle is preferably oriented in such a way that the insert element can be inserted into the insert receptacle in the direction of an insertion direction running transversely to the sealing surface. In the installed position, the direction of insertion preferably runs in the horizontal direction. The direction of use is preferably parallel to the orientation of the pivot axis.

In einer zweiten Ausführungsform mündet die Einsatzaufnahme zwischen der zweiten Abzweigstelle und dem Rohraustritt in das Ablaufrohr. Die Einsatzaufnahme ist vorzugsweise derart orientiert, dass das Einsatzelement in Richtung einer rechtwinklig zur Dichtfläche verlaufenden Einsetzrichtung in die Einsatzaufnahme einsetzbar ist. In Einbaulage verläuft die Einsetzrichtung vorzugsweise in Horizontaler Richtung. Die Einsatzrichtung ist bevorzugt quer oder rechtwinklig zur Orientierung der Schwenkachse.In a second embodiment, the insert receptacle opens into the drain pipe between the second branch point and the pipe outlet. The insert receptacle is preferably oriented in such a way that the insert element can be inserted into the insert receptacle in the direction of an insertion direction running at right angles to the sealing surface. In the installed position, the direction of insertion preferably runs in the horizontal direction. The direction of use is preferably transverse or perpendicular to the orientation of the pivot axis.

Vorzugsweise ist der Ventilkörper gegenüber der Lagerstelle, insbesondere der Lageröffnung, des Einsatzelements an einer weiteren Lagerstelle, die am Ablaufrohr angeordnet ist, gelagert. Das heisst, der Ventilkörper ist teilweise am Einsatzelement und teilweise an der weiteren Lagerstelle angeordnet.The valve body is preferably mounted opposite the bearing point, in particular the bearing opening, of the insert element at a further bearing point, which is arranged on the drain pipe. This means that the valve body is partly arranged on the insert element and partly on the further bearing point.

Vorzugsweise ist das Betätigungselement ein Bowdenzug mit einer Hülle und einem darin gelagerten Kabel, welches Kabel auf den Ventilkörper wirkt, wobei die Hülle am Einsatzelement gelagert ist. Das Kabel wirkt insbesondere auf das freie Ende des Hebelarms der Lagerachse. Alternativerweise kann das Betätigungselement auch ein elektrischer Aktuator, wie ein Motor oder ein Servomotor sein, oder ein pneumatischer Aktuator sein.Preferably the actuator is a bowden cable having a sheath and a housing therein mounted cable, which cable acts on the valve body, the sheath being mounted on the insert element. The cable acts in particular on the free end of the lever arm of the bearing axle. Alternatively, the actuating element can also be an electric actuator, such as a motor or a servo motor, or it can be a pneumatic actuator.

Vorzugsweise weisen das Einsatzelement und/oder die Einsatzaufnahme einen Einschnitt für die Durchführung des Bowdenzugs auf. Durch den Einschnitt kann der Bowdenzug einfach aus dem Einsatzelement hinausgeführt werden, wobei die Platzverhältnisse optimal nutzbar sind.The insert element and/or the insert receptacle preferably have an incision for the Bowden cable to pass through. The Bowden cable can be easily routed out of the insert element through the incision, with the space conditions being optimally usable.

In der Folge werden nun einige weitere bevorzugte optionale Merkmale beschrieben.Some other preferred optional features will now be described below.

Vorzugsweise umfasst der Ventilkörper, insbesondere die Ventilklappe, ein Dichtungselement, welches in der Verschlusslage auf der Dichtfläche aufliegt. Das Dichtungselement ist vorzugsweise ein Dichtring oder eine Profildichtung.The valve body, in particular the valve flap, preferably comprises a sealing element which rests on the sealing surface in the closed position. The sealing element is preferably a sealing ring or a profile seal.

Vorzugsweise ist die Dichtfläche eine sich vollständig um die Mittelachse herumerstreckende Ringfläche.Preferably, the sealing surface is an annular surface extending completely around the central axis.

Vorzugsweise wird die Dichtfläche durch eine Aufweitung des Ventilabschnittes bereitgestellt, wobei der Querschnitt des Ventilabschnittes in Fliessrichtung gesehen nach der Dichtfläche grösser ist als vor der Dichtfläche. Hierdurch kann eine besonders einfache Anordnung der Dichtfläche erreicht werden.The sealing surface is preferably provided by a widening of the valve section, with the cross section of the valve section, viewed in the direction of flow, being larger after the sealing surface than before the sealing surface. As a result, a particularly simple arrangement of the sealing surface can be achieved.

Zudem wird durch die Querschnittsvergrösserung nach der Dichtfläche erreicht, dass die Strömung nicht negativ beeinflusst wird. Es können zudem auch keine Feststoffe, wie Haare und dergleichen, an der Dichtfläche hängen bleiben.In addition, the enlargement of the cross section after the sealing surface ensures that the flow is not negatively influenced. In addition, no solids, such as hair and the like, can get caught on the sealing surface.

Vorzugsweise wird der Ventilkörper in Fliessrichtung geöffnet und gegen die Fliessrichtung geschlossen.The valve body is preferably opened in the direction of flow and closed against the direction of flow.

Vorzugsweise erstrecken sich die beiden Abzweigstellen von dem in der Horizontalen liegenden Ventilabschnitt rechtwinklig zur Mittelachse in Einbaulage entgegen der Lotrichtung weg. Das heisst, in Einbaulage erstrecken sich die Abzweigstellen und somit auch das Überlaufrohr vom Ventilabschnitt nach oben hin weg.Preferably, the two branching points extend from the horizontal lying valve section at right angles to the central axis away in the installed position against the plumb direction. This means that in the installed position, the branch points and thus also the overflow pipe extend upwards away from the valve section.

Vorzugsweise erstreckt sich das Überlaufrohr vom Ventilabschnitt in Einbaulage ausschliesslich nach oben hin. Das heisst, dass bezüglich einer Horizontalebene, die sich durch die Mittelachse erstreckt und in Einbaulage in der Horizontalen liegt, erstreckt sich das Überlaufrohr ausschliesslich nach oben.In the installed position, the overflow pipe preferably extends exclusively upwards from the valve section. This means that with respect to a horizontal plane that extends through the center axis and is horizontal in the installed position, the overflow pipe extends exclusively upwards.

Die Abzweigstellen und das Ventil liegen bevorzugt im Ventilabschnitt, der in der Horizontalen liegt, was den benötigen Einbauraum für die Ablaufanordnung kompakter gestalten lässt.The branch points and the valve are preferably located in the valve section that is horizontal, which means that the installation space required for the drain arrangement can be made more compact.

Vorzugsweise erstreckt sich das dem Rohreintritt in Fliessrichtung anschliessende Rohrstück im Wesentlichen in der Horizontalen oder in einem Winkel von maximal 20° winklig geneigt zur Horizontalen. Das sich dem Ventilabschnitt in Fliessrichtung anschliessende Rohrstück erstreckt sich im Wesentlichen in der Vertikalen.The piece of pipe adjoining the pipe inlet in the direction of flow preferably extends essentially in the horizontal or at an angle of at most 20° inclined to the horizontal. The piece of pipe adjoining the valve section in the direction of flow extends essentially in the vertical.

Vorzugsweise wird das Überlaufrohr als u-förmiges Rohrstück bereitgestellt.The overflow pipe is preferably provided as a U-shaped piece of pipe.

Alternativerweise wird das Überlaufrohr durch einen im Sanitärartikel liegenden Kanal bereitgestellt. Das heisst, dass das Überlaufrohr Teil des Sanitärartikels ist. Vorzugsweise wird das Überlaufrohr über eine mechanische Steckverbindung mit den beiden Abzweigstellen verbunden.Alternatively, the overflow pipe is provided by a channel located in the sanitary article. This means that the overflow pipe is part of the sanitary item. The overflow pipe is preferably connected to the two branch points via a mechanical plug connection.

Weitere Ausführungsformen sind in den abhängigen Ansprüchen angegeben.Further embodiments are specified in the dependent claims.

BESCHREIBUNG BEVORZUGTER AUSFÜHRUNGSFORMENDESCRIPTION OF PREFERRED EMBODIMENTS

In den Figuren wird eine Ablaufanordnung 1 zum Anschluss an einen Sanitärartikel gezeigt. Der Sanitärartikel ist typischerweise ein Waschtisch.The figures show a drain arrangement 1 for connection to a sanitary article. The sanitary article is typically a vanity.

Die Figuren 1 bis 10 zeigen eine erste Ausführungsform der Ablaufanordnung 1 und die Figuren 11 bis 13 zeigen eine zweite Ausführungsform der Ablaufanordnung 1. In der Folge wird nun unter Bezugnahme auf beide Ausführungsformen der grundsätzliche Aufbau der Ablaufanordnung 1 erläutert.the Figures 1 to 10 show a first embodiment of the flow arrangement 1 and FIG Figures 11 to 13 show a second embodiment of the flow arrangement 1. The basic structure of the flow arrangement 1 will now be explained below with reference to both embodiments.

Die Ablaufanordnung 1 umfasst ein Ablaufrohr 3 mit einem Rohreintritt 4 und einem Rohraustritt 5, einen in einem Ventilabschnitt 6 des Ablaufrohrs 3 angeordnetes Ventil 7 und ein Überlaufrohr 10. Mit dem Überlaufrohr 10 wird das Ventil 7 derart überbrückt, dass im Falle einer unbeabsichtigten Blockierung des Ventils 7 das Wasser bei ansteigendem Wasserstand im Sanitärartikel dennoch über das Überlaufrohr 10 abfliessen kann.The drain arrangement 1 comprises a drain pipe 3 with a pipe inlet 4 and a pipe outlet 5, a valve 7 arranged in a valve section 6 of the drain pipe 3 and an overflow pipe 10. The overflow pipe 10 bypasses the valve 7 in such a way that in the event of an unintentional blockage of the Valve 7, the water can still flow out via the overflow pipe 10 when the water level in the sanitary article rises.

Im Ventilabschnitt 6 des Ablaufrohrs 3 ist ein Ventil 7 angeordnet. Das Ventil 7 umfasst eine Dichtfläche 8 und einen Ventilkörper 9, wobei der Ventilkörper 9 mit einem Betätigungselement 15 von einer Verschlusslage in eine Offenlage von der Dichtfläche 8 weg bewegbar ist. Die Bewegbarkeit des Ventilkörpers 9 wird in den Schnittdarstellungen der Figuren 7 und 8 genauer gezeigt. In der Figur 7 befindet sich der Ventilkörper 9 in seiner Offenlage, das heisst er ist beabstandet von der Dichtfläche 8 und in der Figur 8 befindet sich der Ventilkörper 9 in seiner Verschlusslage, das heisst der Ventilkörper 9 liegt auf der Dichtfläche 8 auf. Wenn der Ventilkörper 9 in Verschlusslage ist und sich das Wasser im Sanitärartikel anstaut, so kann das Wasser dann im Überlaufrohr 10 ebenfalls ansteigen und über das Überlaufrohr 10 entsprechend abfliessen. Der Ventilkörper 9 weist weiter eine Dichtung 46 auf, welche den Ventilkörper 9 gegenüber der Dichtfläche 8 abdichtet.A valve 7 is arranged in the valve section 6 of the drain pipe 3 . The valve 7 comprises a sealing surface 8 and a valve body 9, the valve body 9 being movable away from the sealing surface 8 from a closed position into an open position with an actuating element 15. The mobility of the valve body 9 is in the sectional views of Figures 7 and 8 shown in more detail. In the figure 7 is the valve body 9 in its open position, that is, it is spaced from the sealing surface 8 and in the figure 8 the valve body 9 is in its closed position, that is to say the valve body 9 rests on the sealing surface 8 . When the valve body 9 is in the closed position and the water accumulates in the sanitary item, the water can then likewise rise in the overflow pipe 10 and flow out accordingly via the overflow pipe 10 . The valve body 9 also has a seal 46 which seals the valve body 9 against the sealing surface 8 .

Das Überlaufrohr 10 erstreckt sich von einer ersten Abzweigstelle 11 zu einer zweiten Abzweigstelle 12. Die erste Abzweigstelle 11 liegt in Fliessrichtung F des Wassers gesehen vor dem Ventil 7 und die zweite Abzweigstelle 12 liegt in Fliessrichtung F des Wassers gesehen nach dem Ventil 7. Dabei erstreckt sich das Überlaufrohr 10 vom Ablaufrohr 3 weg und ist in Einbaulage im Wesentlichen entgegen der Lotrichtung nach oben orientiert. Das heisst, das Überlaufrohr 10 erstreckt sich in Einbaulage im Wesentlichen entgegen der Lotrichtung nach oben. Das Überlaufrohr 10 ist in den beiden gezeigten Ausführungsformen vom Ablaufrohr 3 getrennt als separates Teil ausgebildet. Das Überlaufrohr 10 kann dabei mit den beiden Abzweigstellen 11, 12 verbunden werden. Hierbei handelt es sich vorzugsweise um eine Steckverbindung, so wie dies von den Figuren 2 und 3 ersichtlich ist. Das heisst, das Überlaufrohr 10 kann in die beiden Abzweigstellen 11, 12 eingesteckt werden. Eine Schweissverbindung wäre auch denkbar.The overflow pipe 10 extends from a first branching point 11 to a second branching point 12. The first branching point 11 is seen in the flow direction F of the water before the valve 7 and the second branching point 12 is seen in the flow direction F of the water after the valve 7. It extends the overflow pipe 10 is away from the drain pipe 3 and is oriented in the installed position essentially counter to the vertical direction upwards. In other words, the overflow pipe 10 extends upwards in the installed position essentially counter to the perpendicular direction. In the two embodiments shown, the overflow pipe 10 is designed separately from the drain pipe 3 as a separate part. The overflow pipe 10 can be connected to the two branch points 11, 12. This is preferably a plug-in connection, such as that of the figures 2 and 3 is evident. This means that the overflow pipe 10 can be inserted into the two branch points 11, 12. A welded connection would also be conceivable.

Von den Figuren 2 und 3 bzw. 11 und 12 ist ersichtlich, dass der Ventilkörper 9 mindestens teilweise an einem Einsatzelement 13 gelagert ist. Das Einsatzelement 13 ist in eine Einsatzaufnahme 14 einsetzbar. Die Einsatzaufnahme 14 ist dabei Teil des Ablaufrohrs 3 und ragt in das Ablaufrohr 3 ein. Durch die Lagerung des Ventilkörpers 9 am Einsatzelement 13 kann der Ventilkörper 9 gemeinsam mit dem Einsatzelement 13 in das Ablaufrohr 3 in den Ventilabschnitt 6 eingesetzt werden. Der Ventilkörper 9 kann zudem mit dem Einsatzelement 13 aus dem Ventilabschnitt 6 entfernt werden, sodass beispielsweise der Ventilkörper 9 ersetzt werden kann. Hierdurch wird der grundsätzliche Einbau bei der Herstellung und die späterer Wartung des Ventilkörpers 9 vereinfacht.Of the figures 2 and 3 and 11 and 12 it can be seen that the valve body 9 is mounted at least partially on an insert element 13 . The insert element 13 can be inserted into an insert receptacle 14 . The insert receptacle 14 is part of the drain pipe 3 and protrudes into the drain pipe 3 . By mounting the valve body 9 on the insert element 13 , the valve body 9 can be inserted together with the insert element 13 into the outlet pipe 3 in the valve section 6 . The valve body 9 can also be removed from the valve section 6 with the insert element 13 so that, for example, the valve body 9 can be replaced. This simplifies the basic installation during manufacture and subsequent maintenance of the valve body 9 .

Der Ventilkörper 9 ist in beiden Ausführungsformen eine Ventilklappe. Die Ventilklappe ist dabei relativ zur Dichtfläche 8 um eine geometrische Schwenkachse A verschwenkbar ausgebildet. Das heisst, die Ventilklappe lässt sich über eine Verschwenkbewegung um die geometrische Schwenkachse A von der Verschlusslage in die Offenlage verschwenken.The valve body 9 is a valve flap in both embodiments. The valve flap is designed to be pivotable about a geometric pivot axis A relative to the sealing surface 8 . This means that the valve flap can be pivoted from the closed position to the open position via a pivoting movement about the geometric pivot axis A.

In der ersten Ausführungsform gemäss den Figuren 1 bis 10 wird die Dichtfläche 8 durch das Ablaufrohr 3 bereitgestellt. Das heisst, die Dichtfläche 8 ist ein integraler Bestandteil des Ablaufrohrs 3. Hierfür weist das Ablaufrohr 3 innenseitig einen entsprechenden Absatz auf, welcher die Dichtfläche 8 bereitstellt. In der zweiten Ausführungsform gemäss den Figuren 11 bis 13 wird die Dichtfläche 8 durch das Einsatzelement 13 selbst bereitgestellt. Das heisst, die Dichtfläche 8 ist ein integraler Bestandteil des Einsatzelementes 13.In the first embodiment according to Figures 1 to 10 the sealing surface 8 is provided by the drain pipe 3. This means that the sealing surface 8 is an integral part of the drain pipe 3. For this purpose, the drain pipe 3 has a corresponding step on the inside, which provides the sealing surface 8. In the second embodiment according to Figures 11 to 13 the sealing surface 8 is provided by the insert element 13 itself. This means that the sealing surface 8 is an integral part of the insert element 13.

In der ersten und der zweiten Ausführungsform verläuft der Ventilabschnitt 6 in Einbaulage derart, dass die Fliessrichtung F im Wesentlichen in einem Winkel winklig geneigt zur Horizontalen H verläuft, und dass die Dichtfläche 8 in Einbaulage im Wesentlichen in einem Winkel winklig geneigt zur Vertikalen V orientiert ist. Dies wird insbesondere in den Figuren 7 und 8 gezeigt. Der Winkel trägt das Bezugszeichen α.In the first and the second embodiment, the valve section 6 runs in the installed position in such a way that the flow direction F runs essentially at an angle to the horizontal H, and that the sealing surface 8 in the installed position is oriented essentially at an angle to the vertical V . This is particularly in the Figures 7 and 8 shown. The angle bears the reference symbol α.

Unter Bezugnahme auf die Figuren 2 bis 10 wird nun die Lagerung der Ventilklappe gemäss der ersten Ausführungsform genauer erläutert. Die Ventilklappe ist an einer Lagerachse 16 gelagert. Die Lagerachse 16 ist in einer Lagerstelle, hier in einer Lageröffnung 17, am Einsatzelement 13 entsprechend gelagert. Die Lagerachse 16 erstreckt sich dabei durch die Lageröffnung 17 hindurch. Gemäss der Figur 4 ist in dieser bevorzugten Ausführungsform die Lagerachse 16 getrennt ausgebildet. Ein erster Teil der Lagerachse 16 ist dabei in der Lageröffnung 17 gelagert und ein zweiter Teil wird hier über eine Schraubverbindung 35 mit dem ersten Teil verbunden. Der Ventilkörper 9 ist dabei am zweiten Teil entsprechend angeformt. Die zweiteilige Ausbildung der Lagerachse 16 hat den Vorteil, dass an einer Schulter 36 an der Lagerachse 16 eine Dichtung 20 angeordnet werden kann. Mit der Dichtung 20 wird im Wesentlichen die Lageröffnung 17 abgedichtet, sodass kein Wasser von Seiten des Ablaufrohrs 3 durch die Lageröffnung 17 nach aussen dringen kann. In anderen Ausführungsformen kann die Lagerachse 16 aber auch einstückig ausgebildet sein.Referring to the Figures 2 to 10 the mounting of the valve flap according to the first embodiment will now be explained in more detail. The valve flap is mounted on a bearing axle 16 . The bearing axle 16 is correspondingly mounted in a bearing point, here in a bearing opening 17, on the insert element 13. The bearing axis 16 extends through the bearing opening 17 . According to the figure 4 is in this one preferred embodiment, the bearing axis 16 is formed separately. A first part of the bearing axle 16 is mounted in the bearing opening 17 and a second part is connected to the first part here via a screw connection 35 . The valve body 9 is correspondingly formed on the second part. The two-part design of the bearing axle 16 has the advantage that a seal 20 can be arranged on a shoulder 36 on the bearing axle 16 . The bearing opening 17 is essentially sealed with the seal 20 so that no water can penetrate from the side of the drain pipe 3 through the bearing opening 17 to the outside. In other embodiments, the bearing axle 16 can also be designed in one piece.

Weiter ist der Ventilkörper 9 gemäss der ersten Ausführungsform gegenüber der Lagerstelle des Einsatzelementes an einer Lagerstelle 31, die am Ablaufrohr 3 angeordnet ist, gelagert. Die Lagerstelle 31 hat hier die Form eines Zapfens, welcher in eine stirnseitig an der Lagerachse 16 angeordnete Öffnung 37 eingreifen kann. Von der Figur 4, welche die Explosivansicht zeigt, kann gut erkannt werden, dass nach der Herstellung der Schraubverbindung 35 das Einsatzelement 13 in die Einsatzaufnahme 14 eingeschoben werden kann, wobei dann die Öffnung 37 in Richtung des Zapfens 31 bewegt wird und diesen entsprechend aufnimmt. Von der Figur 5 wird sodann ersichtlich, dass der Ventilkörper 9 einerseits in der Lageröffnung 17 und andererseits gegenüber der Lageröffnung 17 an der Lagerstelle 31 gelagert ist. Die Lagerstelle 31 und die Lageröffnung 17 liegen in der Einbaulage auf der geometrischen Schwenkachse A.Furthermore, according to the first embodiment, the valve body 9 is mounted opposite the bearing point of the insert element at a bearing point 31 which is arranged on the drain pipe 3 . The bearing point 31 here has the shape of a pin, which can engage in an opening 37 arranged on the end face of the bearing axis 16 . Of the figure 4 , which shows the exploded view, it can be clearly seen that after the screw connection 35 has been produced, the insert element 13 can be pushed into the insert receptacle 14, the opening 37 then being moved in the direction of the pin 31 and receiving it accordingly. Of the figure 5 It can then be seen that the valve body 9 is mounted on the one hand in the bearing opening 17 and on the other hand opposite the bearing opening 17 at the bearing point 31 . The bearing point 31 and the bearing opening 17 are in the installed position on the geometric pivot axis A.

In der zweiten Ausführungsform gemäss den Figuren 11 bis 13, ist die Lagerachse in einer Lagerstelle 18 am Ablaufrohr 3 verschwenkbar gelagert. Die Lagerstelle 18 wird durch eine Lageröffnung bereitgestellt. Die Lagerachse 16 wird dabei durch die Lageröffnung in das Ablaufrohr 3 eingeschoben. Während des Einschiebens kommt dabei die Lagerachse 16 mit der Ventilklappe in Verbindung. Dabei wird die Lagerachse 16 durch eine Öffnung 38 an der Ventilklappe hindurchgeführt.In the second embodiment according to Figures 11 to 13 , The bearing axis is pivotably mounted in a bearing point 18 on the drain pipe 3 . The bearing point 18 is provided by a bearing opening. The bearing axle 16 is pushed into the drain pipe 3 through the bearing opening. During the insertion, the bearing axis 16 comes into contact with the valve flap. The bearing axle 16 is passed through an opening 38 on the valve flap.

Bei beiden Ausführungsformen steht die eigentliche Ventilklappe über einen Abkröpfbereich 2 mit der Lagerachse 16 in Verbindung.In both embodiments, the actual valve flap is connected to the bearing axis 16 via a bent area 2 .

Die Lagerachse 16 weist in beiden Ausführungsformen ein freies Ende 19 auf. Das freie Ende 19 ist dabei das Ende eines Hebelarms 21, welcher im Wesentlichen rechtwinklig von der Lagerachse 16 absteht. Das freie Ende 19 bzw. der Hebelarm 21 ist dabei auf der Seite des Einsatzelementes 13 angeordnet. Das freie Ende 19 steht mit dem besagten Betätigungselement 15 in Verbindung. Über das Betätigungselement 15 kann dabei die Lagerachse 16 entsprechend um die geometrische Schwenkachse A verschwenkt werden. Das freie Ende 19 bzw. der Hebelarm 21, liegen ausserhalb des Ablaufrohrs 3. Das heisst, das freie Ende 19 des Hebelarms 21 ist von ausserhalb des Ablaufrohrs 3 betätigbar. Dies hat den Vorteil, dass die gesamte Betätigungsmechanik ausserhalb der wasserführenden Teile liegt.The bearing axle 16 has a free end 19 in both embodiments. The free End 19 is the end of a lever arm 21 which protrudes from the bearing axis 16 essentially at right angles. The free end 19 or the lever arm 21 is arranged on the side of the insert element 13 . The free end 19 is connected to said actuating element 15. The bearing axis 16 can be correspondingly pivoted about the geometric pivot axis A via the actuating element 15 . The free end 19 or the lever arm 21 lies outside the drain pipe 3. This means that the free end 19 of the lever arm 21 can be actuated from outside the drain pipe 3. This has the advantage that the entire operating mechanism is outside of the water-carrying parts.

In beiden Ausführungsformen ist zudem ein Rückstellelement 22 angeordnet. Das Rückstellelement 22 wirkt dabei auf den Ventilkörper 9. Insbesondere wirkt das Rückstellelement 22 derart auf den Ventilkörper 9, dass dieser in seiner Verschlusslage gehalten wird. Vorzugsweise ist das Rückstellelement 22, wie von der Figur 6 gezeigt, am Einsatzelement 13 gelagert. In der ersten Ausführungsform ist das Rückstellelement 22 eine Blattfeder. In der zweiten Ausführungsform wird das Rückstellelement ebenfalls über ein Federmittel bereitgestellt, welches in den Figuren aber nicht dargestellt ist. Das Rückstellelement 22 hat den grundsätzlichen Vorteil, dass der Ventilkörper 9 in seiner Verschlusslage gehalten wird, was insbesondere bei der Montage bzw. Demontage von Vorteil ist. Hierdurch wird nämlich verhindert, dass der Ventilkörper 9 beim Einsetzen des Einsatzelementes 13 in die Einsatzaufnahme 14 mit der Dichtfläche 8 kollidiert, was unter Umständen zu einer Beschädigung des Ventilkörpers 9 führen könnte.A restoring element 22 is also arranged in both embodiments. The restoring element 22 acts on the valve body 9. In particular, the restoring element 22 acts on the valve body 9 in such a way that it is held in its closed position. Preferably, the restoring element 22, as of the figure 6 shown, mounted on the insert element 13. In the first embodiment, the restoring element 22 is a leaf spring. In the second embodiment, the restoring element is also provided via a spring means, which is not shown in the figures. The restoring element 22 has the fundamental advantage that the valve body 9 is held in its closed position, which is particularly advantageous during assembly and disassembly. This is because this prevents the valve body 9 from colliding with the sealing surface 8 when inserting the insert element 13 into the insert receptacle 14 , which under certain circumstances could result in damage to the valve body 9 .

Bei beiden Ausführungsformen weist das Einsatzelement 13 einen kreiszylindrischen Lagerabschnitt 23 auf. Die Einsatzaufnahme 14 weist weiter einen kreiszylindrischen Lageraufnahmeabschnitt 24 auf. Über die Paarung Lagerabschnitt 23 und Lageraufnahmeabschnitt 24 wird das Einsatzelement 13 in der Einsatzaufnahme 14 gelagert. Zwischen dem Lagerabschnitt 23 und dem Lageraufnahmeabschnitt 24 ist ein Dichtungselement 25 angeordnet.In both embodiments, the insert element 13 has a circular-cylindrical bearing section 23 . The insert receptacle 14 also has a circular-cylindrical bearing receptacle section 24 . The insert element 13 is mounted in the insert receptacle 14 via the pairing of the bearing section 23 and the bearing receiving section 24 . A sealing element 25 is arranged between the bearing section 23 and the bearing receiving section 24 .

Vorzugsweise ist zwischen dem Einsatzelement 13 und der Einsatzaufnahme 14 eine Orientierungsstruktur 26 angeordnet, sodass das Einsatzelement 13 mit dem am Einsatzelement 13 gelagerten Ventilkörper 9 bezüglich der Dichtfläche 8 ausgerichtet werden kann. In der ersten Ausführungsform ist die Orientierungsstruktur eine Nut- und Kammverbindung, wobei am Einsatzelement 13 eine entsprechende Nut 38 angeordnet ist, welche einen Kamm 39 an der Einsatzaufnahme 14 entsprechend aufnimmt. Die Nut 38 ist in der Figur 9 und der Kamm 39 in der Figur 4 ersichtlich.An orientation structure 26 is preferably arranged between the insert element 13 and the insert receptacle 14 so that the insert element 13 is aligned with the valve body 9 mounted on the insert element 13 with respect to the sealing surface 8 can be. In the first embodiment, the orientation structure is a groove and comb connection, with a corresponding groove 38 being arranged on the insert element 13 , which correspondingly accommodates a comb 39 on the insert receptacle 14 . The groove 38 is in the figure 9 and the crest 39 in the figure 4 evident.

In beiden Ausführungsformen umfasst das Einsatzelement 13 weiter ein Sicherungselement 27. Mit dem Sicherungselement 27 ist nach erfolgtem Einsetzen des Einsatzelementes 13 in die Einsatzaufnahme 14 das Einsatzelement 13 zum Ablaufrohr 3 hin mechanisch festlegbar.In both embodiments, the insert element 13 further comprises a securing element 27. After the insert element 13 has been inserted into the insert receptacle 14, the insert element 13 can be mechanically fixed towards the drain pipe 3 with the securing element 27.

In der ersten Ausführungsform ist das Sicherungselement 27 ein Deckel 28, welcher drehbar am Einsatzelement 13 gelagert ist. Der Deckel 28 weist dabei ein Gewinde 29 auf, welches mit einem entsprechend ausgebildeten Gewinde 30 am Ablaufrohr zusammenarbeitet. Durch ein Verdrehen des Deckels 28 greift das Gewinde 29 in das Gewinde 30 ein und der Deckel 28 kann dabei zum Ablaufrohr 3 hin gesichert werden. Von der Figur 5 wird die Lagerung des Deckels 28 am Einsatzelement 13 genauer gezeigt. Der Deckel 28 weist eine Nut 40 auf, welche im Wesentlichen um die Mittelachse des Gewindes 29 umlaufend ausgebildet ist. In diese Nut 40 greift ein umlaufend ausgebildeter Kamm 41, der aussenseitig am Einsatzelement 13 angeordnet ist, ein. Hierdurch kann der Deckel 28 ohne entsprechende Restriktion um die Mittelachse des Gewindes 29 verdreht werden, was dann den entsprechenden Eingriff am Gewinde 30 und das entsprechende Festziehen des Deckels 28 erlaubt. Beim Festziehen des Deckels 28 wird aufgrund der Lagerung das Einsatzelement 13 in der Einsatzaufnahme nicht verdreht. In der zweiten Ausführungsform ist das Sicherungselement 27 am Einsatzelement 13 angeformt und weist im Wesentlichen die Gestalt eines Bajonettverschlusses auf. Dabei greift das Sicherungselement 27 am Einsatzelement 13 in eine Kurvenbahn 42, die im Bereich der Einsatzaufnahme 14 auf Seiten des Ablaufrohrs 3 angeordnet ist, ein.In the first embodiment, the securing element 27 is a cover 28 which is rotatably mounted on the insert element 13 . The cover 28 has a thread 29 which cooperates with a correspondingly designed thread 30 on the drain pipe. By turning the cover 28, the thread 29 engages in the thread 30 and the cover 28 can be secured towards the drain pipe 3. Of the figure 5 the storage of the cover 28 on the insert element 13 is shown in more detail. The cover 28 has a groove 40 which is designed to essentially run around the central axis of the thread 29 . In this groove 40 engages a peripherally formed comb 41 which is arranged on the outside of the insert element 13 . This allows the cap 28 to be rotated about the central axis of the thread 29 without corresponding restriction, which then permits the appropriate engagement with the thread 30 and the appropriate tightening of the cap 28 . When the cover 28 is tightened, the insert element 13 is not twisted in the insert receptacle due to the bearing. In the second embodiment, the securing element 27 is formed on the insert element 13 and essentially has the shape of a bayonet lock. The securing element 27 on the insert element 13 engages in a curved track 42 which is arranged in the area of the insert receptacle 14 on the side of the drain pipe 3 .

Die Einsatzaufnahme 14 gemäss der ersten Ausführungsform mündet zwischen der ersten Abzweigstelle 11 und der zweiten Abzweigstelle 12 in das Ablaufrohr 3 ein. Dabei ist die Einsatzaufnahme 14 derart orientiert, dass das Einsatzelement 13 in Richtung einer quer zur Dichtfläche 8 verlaufenden Einsetzrichtung E in die Einsatzaufnahme einsetzbar ist. Die Einsetzrichtung E wird in den Figuren 2 und 3 mit einem entsprechenden Pfeil gezeigt.The insert receptacle 14 according to the first embodiment opens into the drain pipe 3 between the first branching point 11 and the second branching point 12 . The insert receptacle 14 is oriented in such a way that the insert element 13 can be inserted into the insert receptacle in the direction of an insertion direction E running transversely to the sealing surface 8 . The insertion direction E is in the figures 2 and 3 shown with a corresponding arrow.

Die Einsetzrichtung E ist im Wesentlichen parallel zur geometrischen Schwenkachse A.The insertion direction E is essentially parallel to the geometric pivot axis A.

Anhand der Figuren 4, 9 und 10 wird nun die konkrete Struktur des Einsatzelementes 13 gezeigt. Das Einsatzelement 13 weist einen Boden 42 auf, von welchem sich eine umlaufende Seitenwand 43 wegerstreckt. Die Seitenwand 43 stellt aussenseitig den Lagerabschnitt 23 bereit und im Boden 42 ist die Lagerstelle 47 vorgesehen. Durch Boden 42 und Seitenwand 43 wird ein Innenraum 44 geschaffen, in welchem der Hebelarm 21 und das Rückstellelement 22 vorhanden sind. Der Innenraum 44 ist in der montierten Stellung des Einsatzelementes 13 mindestens teilweise im Inneren der Einsatzaufnahme 14 angeordnet und hier durch den Deckel 28 entsprechend verschlossen. Durch die Seitenwand 43 wird das Betätigungselement zum Hebelarm 21 hingeführt. Dabei ist das Betätigungselement 15 in einem Einschnitt 34 gelagert, welcher sich durch die Seitenwand 43 hindurcherstreckt. Beim Betätigungselement 15 handelt es sich in der gezeigten Ausführungsform um einen Bowdenzug mit einer Hülle 32 und einem darin liegenden Kabel 33, wobei das Kabel 33 auf den Hebelarm 21 wirkt. Die Hülle 32 ist mit ihrem Endbereich im Einschnitt 34 gelagert. Die Lagerung des Bowdenzug direkt am Einsatzelement 13 hat den Vorteil, dass eine Einheit geschaffen werden kann, welche direkt ohne funktionalen Zusammenhang in die Einsatzaufnahme 14 eingesetzt werden kann. Für die Durchführung des Bowdenzugs weist die Einsatzaufnahme 14 im Bereich des Gewindes 30 einen Schlitz 45 auf. Durch diesen Schlitz 45 kann der Bowdenzug entsprechend nach aussen geführt werden. Durch die Anordnung des Schlitzes 45 bzw. des Einschnittes 34 kann dabei die Bauweise kompakter gewählt werden.Based on figures 4 , 9 and 10 the concrete structure of the insert element 13 is now shown. The insert element 13 has a base 42 from which a peripheral side wall 43 extends. The side wall 43 provides the bearing section 23 on the outside and the bearing point 47 is provided in the base 42 . An interior space 44 is created by the base 42 and the side wall 43, in which the lever arm 21 and the restoring element 22 are present. In the installed position of the insert element 13 , the interior space 44 is at least partially arranged inside the insert receptacle 14 and is correspondingly closed here by the cover 28 . The actuating element is guided to the lever arm 21 through the side wall 43 . The actuating element 15 is mounted in an incision 34 which extends through the side wall 43 . In the embodiment shown, the actuating element 15 is a Bowden cable with a sheath 32 and a cable 33 lying therein, the cable 33 acting on the lever arm 21 . The sleeve 32 is mounted in the notch 34 with its end region. The storage of the Bowden cable directly on the insert element 13 has the advantage that a unit can be created which can be inserted directly into the insert receptacle 14 without any functional connection. The insert receptacle 14 has a slot 45 in the area of the thread 30 for the passage of the Bowden cable. The Bowden cable can be guided outwards accordingly through this slot 45 . Due to the arrangement of the slot 45 or the incision 34, the design can be chosen to be more compact.

Das Dichtungselement 25, welches zwischen dem Lagerabschnitt 21 und dem Lageraufnahmeabschnitt 24 angeordnet ist, ist in der gezeigten Ausführungsform ein O-Ring, welcher im Bereich des Übergangs zwischen Boden 42 und Seitenwand 43 angeordnet ist. Das heisst, das Dichtungselement 25 ist ebenfalls am Einsatzelement 13 entsprechend gelagert.In the embodiment shown, the sealing element 25 , which is arranged between the bearing section 21 and the bearing receiving section 24 , is an O-ring which is arranged in the region of the transition between the base 42 and the side wall 43 .

Durch den Fortsatz 47 kann die Führungslänge entsprechend erhöht werden. Der Fortsatz 47 ragt dabei in das Ablaufrohr 3 ein.In the embodiment shown, the bearing opening 17 is present both in the base 42 and in an extension 47 which extends away from the base 42 . Through the extension 47, the guide length can be increased accordingly. The extension 47 protrudes into the drain pipe 3 .

Das Einsatzelement gemäss der zweiten Ausführungsform ist im Wesentlichen zylindrisch ausgebildet. In der gezeigten Ausführungsform ist der Ventilkörper 9 lose in einer Aufnahme 48 am Einsatzelement gelagert. Das heisst, der Ventilkörper 9 kann in die Aufnahme 48 vor der Montage eingesetzt werden. Die Aufnahme 48 erstreckt sich dabei vom Lagerabschnitt 23 in das Einsatzelement 13 hinein. Im Bereich der Aufnahme 48 ist zudem die Dichtfläche 8, mit welcher der Ventilkörper 9 zusammenarbeitet, angeordnet. Das heisst, die Dichtfläche 8 ist hier am Einsatzelement 13 angeordnet. Das Einsatzelement 13 wird mit seinem Lagerabschnitt 23 in den Lageraufnahmeabschnitt 24 eingesetzt. In der Schnittdarstellung kann gut erkannt werden, dass zwei Dichtungselemente 25 angeordnet sind, nämlich ein erstes Dichtungselement in Fliessrichtung F gesehen vor dem Ventilkörper 9 und ein zweites Dichtungselement nach dem Ventilkörper 9 . Weiter umfasst das Einsatzelement 13 einen Durchgang 49. Der Durchgang 49 kommt dabei derart zu liegen, dass dieser im Bereich der zweiten Abzweigstelle 12 liegt und einen Teil des Ablaufrohrs 3 bereitstellt.
