Die Überlauf- und Ablaufgarnitur 1 besitzt ein Gehäuse 2, das an der Unterseite einer Ablauföffnung 8 eines hier lediglich angedeuteten Sanitärkörpers 7 angeordnet ist. Der Sanitärkörper 7 ist in diesem Fall eine Badewanne, kann jedoch auch beispielsweise ein Waschtisch, ein Waschbecken, ein Bidet oder dergleichen sein. Der Überlauf des Sanitärkörpers 7 wird durch einen hier nur teilweise dargestellten verdeckten Überlauf U gebildet, der an das Gehäuse 2 angeschlossen ist und der sich verdeckt unter bzw. hinter dem Sanitärkörper 7 erstreckt. Verdeckte Überläufe sind an sich bekannt und es wird hierzu auf die bereits oben genannte EP 0 446 177 A des Anmelders verwiesen. Dieser Überlauf U weist ein Rohr 9 auf, das ein Steigrohr bildet und schliesslich in einem hier nicht gezeigten Rücklaufrohr über eine Öffnung 13 in eine Kammer 24 des Gehäuses 2 führt. Das Gehäuse 2 besitzt eine oben offene Ausnehmung 36, die ein Gewinde 37 aufweist, und in die von oben ein Flansch 12 eingeschraubt ist, der das Gehäuse 2 am Rande der Öffnung 8 festlegt. Die Ausnehmung 36 und der Flansch 12 bilden eine Sammelmulde S. In diese Sammelmulde S mündet das Rohr 9. Zudem ist in der Sammelmulde S ein Auslaufventil A angeordnet.The overflow and drain fitting 1 has a housing 2, which is arranged on the underside of a drain opening 8 of a sanitary body 7 merely indicated here. The sanitary body 7 is in this case a bathtub, but may also be for example a vanity, a sink, a bidet or the like. The overflow of the sanitary body 7 is formed by a hidden overflow U shown here only partially, which is connected to the housing 2 and which extends concealed under or behind the sanitary body 7. Hidden overflows are known per se and it is this to the already mentioned above EP 0 446 177 A referenced by the applicant. This overflow U has a tube 9, which forms a riser and finally leads in a return pipe, not shown here via an opening 13 into a chamber 24 of the housing 2. The housing 2 has an open-topped recess 36, which has a thread 37, and in which a flange 12 is screwed from above, which defines the housing 2 at the edge of the opening 8. The recess 36 and the flange 12 form a sump S. In this sump S opens the tube 9. In addition, an outlet valve A is arranged in the sump S.

Das Gehäuse 2 besitzt über der Öffnung 13 einen Durchgang 14, in den eine Mündung 35 eines Stutzens 10 von oben eingerastet ist. Der Stutzen 10 bildet einen Auslaufkanal 11 und besitzt mehrere Rastlippen 35, die im Durchgang eingerastet sind. Zudem ist an der Aussenseite der Mündung 35 ein Dichtungsring 15 angeordnet, der den Stutzen 10 gegenüber dem Gehäuse 2 abdichtet. Der Stutzen 10 ist mit einer Mutter 25 mit einer Auslaufleitung 26 verbunden. Wasser aus dem Sanitärapparat 7 oder dem Überlauf U gelangt in Richtung des Pfeils 32 in den Stutzen 10 und in Richtung des Pfeils 33 in die Auslaufleitung 26.The housing 2 has over the opening 13 a passage 14 into which a mouth 35 of a nozzle 10 is engaged from above. The nozzle 10 forms an outlet channel 11 and has a plurality of locking lips 35 which are engaged in the passage. In addition, on the outside of the mouth 35, a sealing ring 15 is arranged, which seals the nozzle 10 relative to the housing 2. The nozzle 10 is connected to a nut 25 with a discharge line 26. Water from the sanitary appliance 7 or the overflow U reaches in the direction of the arrow 32 in the nozzle 10 and in the direction of the arrow 33 in the outlet line 26th

Das Auslaufventil A wird durch einen Verschlussstöpsel 3 und einen Ventilsitz 4 eines in das Gehäuse 2 von oben eingesetzten Rohres 5 gebildet. Das Rohr 5 ragt mit einem unteren Ende in die Kammer 24, so dass Wasser in dieser Kammer 24 einen Geruchsverschluss bildet. Der Stöpsel 3 kann mit einem Betätigungshebel 6 in die in Figur 1 gezeigte Position angehoben werden. Dieser Betätigungshebel 6 ist in der Kammer 24 schwenkbar gelagert und wird in an sich bekannter Weise von einem hier nicht gezeigten Gestänge von Hand betätigt. In der Figur 1 ist das Auslaufventil A geöffnet. Der Stöpsel 3 ist wie ersichtlich durch den Betätigungshebel 6 angehoben. In der Figur 2 ist das Auslaufventil A geschlossen. Hierbei liegt ein Dichtungsring 38 auf dem Ventilsitz 4 auf. Beim Schliessen des Auslaufventils A fällt der Verschlusskörper 3 durch sein Eigengewicht in die in Figur 2 gezeigte geschlossene Position.The outlet valve A is formed by a closure plug 3 and a valve seat 4 of a tube 5 inserted into the housing 2 from above. The tube 5 projects with a lower end into the chamber 24 so that water in this chamber 24 forms an odor trap. The plug 3 can with an operating lever 6 in the in FIG. 1 be raised position shown. This actuating lever 6 is pivotally mounted in the chamber 24 and is operated in a conventional manner by a linkage, not shown here by hand. In the FIG. 1 is the outlet valve A open. The plug 3 is raised as shown by the operating lever 6. In the FIG. 2 the outlet valve A is closed. In this case, a sealing ring 38 rests on the valve seat 4. When closing the outlet valve A of the closure body 3 falls by its own weight in the in FIG. 2 shown closed position.

In die Sammelmulde S ist von oben eine Einheit 18 eingesetzt, die einen Ablaufdeckel 17 sowie ein unterseitig an diesen befestigtes Rückschlagventil R aufweist. Der Deckel 17 übergreift mit einem Rand 17a den Flansch 12 und weist an einer Unterseite 19 einen Träger 28 auf, an dem der Deckel 17 am Flansch 12 abgestützt ist. Die Einheit 18 ist somit auf dem Flansch 12 abgestützt, kann jedoch zusammen mit dem Rückschlagventil R aus dem Flansch 12 bzw. der Sammelmulde S herausgehoben werden.In the sump S from above, a unit 18 is used, which has a drain cover 17 and a bottom side attached to this check valve R. The lid 17 engages over an edge 17 a, the flange 12 and has on a bottom 19 a support 28, on which the lid 17 is supported on the flange 12. The unit 18 is thus supported on the flange 12, but can be lifted together with the check valve R from the flange 12 and the sump S respectively.

Das Rückschlagventil R besitzt einen Verschlusskörper 22, der ringförmig ausgebildet ist und eine unten offene und ebenfalls ringförmige Luftkammer 22a besitzt. Der Verschlusskörper 22 ist als Schwimmer ausgebildet und mit mehreren nach oben gerichteten Greifarmen 27 an einem tellerförmigen Dichtungselement 20 vertikal begrenzt verschieblich gelagert. Diese Greifarme 27 sind am oberen Ende hakenförmig ausgebildet und greifen jeweils in einen Schlitz 39 des Dichtungselementes 20 ein.The check valve R has a closure body 22 which is annular and has a downwardly open and also annular air chamber 22a. The closure body 22 is designed as a float and mounted with a plurality of upwardly directed gripping arms 27 on a plate-shaped sealing member 20 vertically displaced limited. These gripping arms 27 are hook-shaped at the upper end and each engage in a slot 39 of the sealing element 20 a.

In den Flansch 12 ist ein Führungsring 23 eingesetzt, der seitlich am Flansch 12 abgestützt und im oberen Bereich des Flansches 12 angeordnet ist. Der in seinem Aussendurchmesser etwas kleinere Verschlusskörper 22 ist koaxial zu diesem Ring 23 angeordnet und befindet sich in der in Figur 1 gezeigten Position im Abstand zu diesem Ring 23. In dieser Position ist das Rückschlagventil R offen. Zwischen einem konischen Ventilsitz 21 des Dichtungselementes 20 und dem Verschlusskörper 22 besteht ein ringförmiger Durchlass 40, durch welchen Wasser in Richtung des Pfeiles 30 aus dem Sanitärkörper 7 in die Sammelmulde S gelangen kann. Dieser Durchlass 40 ist in der Figur 2 geschlossen. Der Verschlusskörper 22 liegt hier infolge seines Auftriebes in Wasser 41 am konischen Ventilsitz 21 des Dichtungselementes 20 an. Der Verschlusskörper 22 wird durch den Auftrieb am Ventilsitz 21 angepresst. Das Rückschlagventil R ist damit geschlossen. Fällt der Auftrieb weg, so fällt der Verschlusskörper 22 wieder in die in Figur 1 gezeigte Position. In der oberen Position gemäss Figur 2 liegt der Verschlusskörper 22 an seinem Umfang dicht am Führungsring 23 an.In the flange 12, a guide ring 23 is inserted, which is laterally supported on the flange 12 and disposed in the upper region of the flange 12. The slightly smaller in its outer diameter closure body 22 is arranged coaxially with this ring 23 and is located in the in FIG. 1 shown position at a distance from this ring 23. In this position, the check valve R is open. Between a conical valve seat 21 of the sealing element 20 and the closure body 22 is an annular passage 40, through which water in the direction of arrow 30 from the sanitary body 7 can get into the sump S. This passage 40 is in the FIG. 2 closed. The closure body 22 is due to its buoyancy in water 41 at the conical valve seat 21 of the sealing element 20 here. The closure body 22 is pressed by the buoyancy on the valve seat 21. The check valve R is closed. If the buoyancy disappears, then the closure body 22 falls back into the in FIG. 1 shown position. In the upper position according to FIG. 2 is the closure body 22 at its periphery close to the guide ring 23 at.

Das Dichtungselement 20 besteht vorzugsweise aus einem gummielastischen Werkstoff und ist wie bereits erwähnt tellerförmig ausgebildet. Ein mittiger angeformter und nach oben gerichteter Zapfen 42 ist in eine Vertiefung 43 des Deckel 17 eingesetzt. Das Dichtungselement 20 ist zudem am Träger 28 abgestützt. Der Führungsring 23 und der Verschlusskörper 22 sind separat hergestellte Einzelteile, die ausgewechselt werden können. Dies gilt auch für das Dichtungselement 20. Wird die Einheit 20 aus der Sammelmulde S herausgehoben, so wird ebenfalls der Führungsring 23 mitgenommen, da dieser innenseitig eine konische Fläche 44 aufweist, an welcher der Verschlusskörper 22 beim Herausheben der Einheit 18 anliegt. Wird die Einheit 18 in die Sammelmulde S eingesetzt, so wird der Führungsring 23 durch den Träger 28 in die in den Figuren 1 und 2 gezeigte Position gebracht. Der Verschlusskörper 22 fällt durch sein Eigengewicht in die in Figur 1 gezeigte Position, in welcher er durch die Greifarme 27 gehalten wird.The sealing element 20 preferably consists of a rubber-elastic material and, as already mentioned, is dish-shaped. A central molded and upwardly directed pin 42 is inserted into a recess 43 of the lid 17. The sealing element 20 is also supported on the carrier 28. The guide ring 23 and the closure body 22 are separately manufactured items that can be replaced. This also applies to the sealing element 20. If the unit 20 lifted out of the sump S, so the guide ring 23 is also taken, since this has on the inside a conical surface 44, against which the closure body 22 when lifting the unit 18 is applied. If the unit 18 is inserted into the sump S, the guide ring 23 by the carrier 28 in the in the FIGS. 1 and 2 shown position. The closure body 22 falls by its own weight in the in FIG. 1 shown position in which it is held by the gripping arms 27.

Wasser im Sanitärkörper 7 gelangt in Richtung des Pfeiles 30 durch die Öffnung 40 in die Sammelmulde S und durch das offene Auslaufventil A in die Kammer 24. Die Kammer 24 ist üblicherweise mit hier nicht gezeigtem Wasser gefüllt, in das eine Leitwand 34 eintaucht. Das Wasser gelangt in den Richtungen der Pfeile 31 und 32 durch die Mündung 35 des Stutzens 10 nach oben in den Auslauflcanal 11 und in Richtung des Pfeiles 33 im Wesentlichen horizontal in die Auslaufleitung 26, die mit der Mutter 25 dicht am Stutzen 10 angeschlossen ist.
Ist das Auslaufventil A geschlossen und das Rückschlagventil R offen, so kann der Sanitärkörper 7 mit Wasser gefüllt werden. Ein Teil des Wassers gelangt durch das Rohr 9 in den Überlauf U. In diesem steigt entsprechend das Niveau. Ist eine hier nicht gezeigte Überlaufkante des Überlaufs U erreicht, so fliesst Wasser durch das hier nicht gezeigte Rücklaufrohr zur Öffnung 13 und damit in die Kammer 24. Von dieser gelangt das Wasser in den Richtungen der Pfeile 32 und 33 in die Auslaufleitung 26. Damit ist gewährleistet, dass das Wasser im Sanitärkörper 7 ein vorbestimmtes Niveau nicht überschreiten kann. Dieses Niveau entspricht der Überlaufkante des Überlaufs U.The FIG. 1 shows the clothing 1 in the normal position. The check valve R and the outlet valve A are open. Water in the sanitary body 7 passes in the direction of arrow 30 through the opening 40 in the sump S and through the open outlet valve A into the chamber 24. The chamber 24 is usually filled with not shown here water into which a guide wall 34 is immersed. The water passes in the directions of arrows 31 and 32 through the mouth 35 of the nozzle 10 upwards in the outlet channel 11 and in Direction of the arrow 33 substantially horizontally in the discharge line 26 which is connected to the nut 25 close to the nozzle 10.
If the outlet valve A is closed and the check valve R is open, then the sanitary body 7 can be filled with water. Part of the water passes through the pipe 9 in the overflow U. In this increases accordingly the level. If an overflow edge U of the overflow U, not shown here, is reached, then water flows through the return pipe, not shown here, to the opening 13 and thus into the chamber 24. From this, the water passes in the directions of the arrows 32 and 33 into the discharge line 26. This is ensures that the water in the sanitary body 7 can not exceed a predetermined level. This level corresponds to the overflow edge of the overflow U.

Bildet sich in der Kammer 24 ein Rückstau, beispielsweise durch einen Überdruck in der Auslaufleitung 26, so steigt das Wasserniveau in der Kammer 24 an. Der Verschlusskörper 23 wird dadurch angehoben und von unten gelangt Wasser in die Sammelmulde S, wie dies in Figur 2 angedeutet ist. In der Sammelmulde S befindliches Wasser 41 verleiht dem Verschlusskörper 22 einen Auftrieb und schliesslich gelangt dieser Verschlusskörper 22 in die in Figur 2 gezeigte Position. In dieser Position ist der Verschlusskörper 22 sowohl gegenüber dem Führungsring 23 als auch gegenüber dem Ventilsitz 21 abgedichtet. Der Führungsring 23 bildet damit ein Dichtungsmittel sowie einen Anschlag für den Verschlusskörper 22. Das Wasser 41, das in der Regel Schmutzwasser ist, kann deshalb auch bei einem Überdruck in der Kammer 24 nicht in den Sanitärkörper 7 austreten. Kann das Wasser aus der Sammelmulde S wieder auslaufen, so fällt der Verschlusskörper 22 wieder in die in Figur 1 gezeigte Position, in welcher das Rückschlagventil R wieder offen ist. Bei jedem Rückstau bzw. Überdruck in der Auslaufleitung 26 wird wie erläutert das Rückschlagventil R sofort wieder geschlossen.If a backflow forms in the chamber 24, for example due to an overpressure in the discharge line 26, the water level in the chamber 24 rises. The closure body 23 is thereby lifted and from below water enters the sump S, as in FIG. 2 is indicated. In the sump S located water 41 gives the closure body 22 a buoyancy and finally reaches this closure body 22 in the in FIG. 2 shown position. In this position, the closure body 22 is sealed both with respect to the guide ring 23 and with respect to the valve seat 21. The guide ring 23 thus forms a sealant and a stop for the closure body 22. The water 41, which is usually dirty water, therefore can not escape into the sanitary body 7 even at an overpressure in the chamber 24. Can the water from the sump S expire again, the closure body 22 falls back into the in FIG. 1 shown position in which the check valve R is open again. At each backwater or overpressure in the discharge line 26, the check valve R is immediately closed again as explained.

Ist eine Reinigung erforderlich, so wird die Einheit 18 am Deckel 17 aus der Sammelmulde S herausgehoben. Der Verschlusskörper 3 kann in die in Figur 1 angehobene Stellung gebracht und ebenfalls von oben herausgehoben werden. Damit ist auch das Rohr 5 für die Reinigung zugänglich. Nach der Reinigung wird der Verschlussstöpsel 3 wieder von oben in das Rohr 5 eingesetzt. Anschliessend wir die Einheit 18 von oben in den Flansch 12 eingesetzt. Die Garnitur 1 ist damit bereits wieder einsatzbereit.If cleaning is required, the unit 18 is lifted on the cover 17 from the sump S. The closure body 3 can in the in FIG. 1 raised position and also lifted from above. Thus, the tube 5 is accessible for cleaning. After cleaning, the sealing plug 3 is inserted again from above into the tube 5. Subsequently, the unit 18 is inserted from above into the flange 12. The clothing 1 is thus ready for use again.

Bei der Überlauf- und Ablaufgarnitur 1 ist der Stutzen 10 für den Auslauf oben am Gehäuse 2 angeordnet. Dies ist bei einer Badewanne zweckmässig. Bei einem Waschbecken oder einem anderen Sanitärkörper kann der Auslauf jedoch auch unten am Boden des Gehäuses 2 oder seitlich an diesem angeordnet sein. Ebenfalls können das Rohr 9 und die Öffnung 13 des Überlaufs U an anderen Positionen des Gehäuses 2 angeordnet sein.In the overflow and drain fitting 1, the nozzle 10 is arranged for the outlet at the top of the housing 2. This is useful in a bathtub. In a sink or other sanitary body, however, the spout may also be arranged at the bottom of the bottom of the housing 2 or laterally thereto. Also, the tube 9 and the opening 13 of the overflow U may be disposed at other positions of the housing 2.
