Abstract

Overflow and drainage fitting for sanitary appliances comprises an overflow pipe connected to a drainage opening and having in the flow direction firstly a vertical channel and after an overflow edge a return channel. On reaching a pre-determined water level (27) in the sanitary appliance, the overflow pipe forms a closed flow (34) that removes water from the sanitary appliance. Preferred Features: The discharge rate of the closed flow is greater than a maximally permissible incoming rate, especially greater than about 0.61/sec.

Description

Die Erfindung betrifft eine Überlauf- und Ablaufgarnitur für sanitäre Apparate, insbesondere Waschtische, Waschbecken, Spülbecken, Badewannen und Bidet, mit einem Überlaufrohr, das mit der Ablauföffnung verbunden ist und in Strömungsrichtung gesehen zuerst einen Steigkanal und nach einer Überlaufkante einen Rücklaufkanal aufweist.The invention relates to an overflow and drain set for sanitary Apparatus, in particular washstands, wash basins, sinks, Bathtubs and bidet, with an overflow pipe that matches the Drain opening is connected and seen first in the flow direction a riser and a return channel after an overflow edge having.

Eine Überlauf- und Ablaufgarnitur der genannten Gattung ist im Stand der Technik aus der EP 0 446 177 A des Anmelders bekannt geworden. Bei dieser ist der Überlauf versteckt angeordnet, wobei die Überlaufkante das maximale Niveau des Wassers im Sanitärapparat bestimmt. Eine weitere Überlauf- und Ablaufgarnitur mit einem verdeckt angeordneten Überlaufrohr ist zudem aus der EP 0 098 757 bekannt geworden. Bei den-bekannten Überlauf- und Ablaufgarnituren wird als nachteilig angesehen, dass sie vergleichsweise viel Raum beanspruchen und bei engen Raumverhältnissen, insbesondere hinter Badewannen und Waschtischen kaum oder nicht montierbar sind.An overflow and waste set of the type mentioned is in State of the art from EP 0 446 177 A of the applicant known become. In this the overflow is hidden, whereby the overflow edge the maximum level of water in the sanitary apparatus certainly. Another overflow and waste set with a concealed overflow pipe is also from the EP 0 098 757 became known. With the well-known overflow and Drain fittings are considered disadvantageous in that they are comparative take up a lot of space and in tight spaces, especially behind bathtubs and vanities or are not mountable.

Der Erfindung liegt die Aufgabe zugrunde, eine Überlauf- und Ablaufgarnitur der genannten Art zu schaffen, die weniger Platz beansprucht, aber dennoch leistungsfähig und sicher ist.The invention has for its object an overflow and drain set of the type mentioned to create the less space claimed, but still powerful and safe.

Die Aufgabe ist bei einer gattungsgemässen Überlauf- und Ablaufgarnitur dadurch gelöst, dass das Überlaufrohr beim Erreichen eines vorbestimmten Wasserniveaus im Sanitärapparat mit einer geschlossenen Strömung Wasser absaugt. Wird ein sanitärer Apparat, beispielsweise eine Badewanne über das vorgesehene Niveau gefüllt, so bildet sich im Überlaufrohr eine geschlossene Strömung, die mit hoher Leistung das über dem Niveau vorhandene Wasser absaugt. Aufgrund der hohen Leistung einer geschlossenen Strömung kann das Überlaufrohr mit wesentlich kleinerem Durchmesser bzw. kleinerer Querschnittfläche als bisher hergestellt werden. Aufgrund des kleineren Durchmessers des Überlaufrohres ist eine entsprechend kleinere und weniger Platz beanspruchende Ausführung möglich. Die kleinere Baugrösse bedeutet aber auch einen geringeren Materialverbrauch und damit kleinere Herstellungskosten sowie ein kleineres Transportvolumen.The task is with a generic overflow and drain set solved that the overflow pipe when reaching a predetermined water level in the sanitary apparatus with a closed flow sucks water. Becomes a sanitary apparatus, for example a bathtub above the intended level filled, a closed flow forms in the overflow pipe, the high-performance water above the level sucks. Due to the high performance of a closed The overflow pipe can flow with a much smaller diameter or smaller cross-sectional area than previously produced become. Due to the smaller diameter of the overflow pipe is a correspondingly smaller and less space-consuming Execution possible. The smaller size also means lower material consumption and thus lower manufacturing costs as well as a smaller transport volume.

Nach einer Weiterbildung der Erfindung sind Mittel zur Unterbrechung der Absaugströmung vorgesehen. Damit ist es möglich, die geschlossene Strömung beim Erreichen des gewünschten Niveaus gezielt und sicher zu unterbrechen und damit das gewünschte Niveau einzustellen und ein Leersaugen der Wanne zu verhindern. Eine besonders einfache und sichere Ausführung dieser Mittel weist ein kommunizierendes Rohr auf, das oben offen ist und das oberhalb der Überlaufkante mit dem Überlaufrohr verbunden ist. Fällt bei geschlossener Strömung das Niveau im kommunizierenden Rohr auf ein vorbestimmtes Niveau, so wird durch einströmende Luft in das Überlaufrohr die geschlossene Strömung unterbrochen.According to a development of the invention, means for interruption the suction flow provided. So it is possible to closed flow targeted when reaching the desired level and safely interrupt and thus the desired level adjust and prevent the tub from being emptied. A particularly simple and safe execution of these agents a communicating pipe that is open at the top and that above the overflow edge is connected to the overflow pipe. falls when the flow is closed, the level in the communicating pipe to a predetermined level, the air flowing in the overflow pipe interrupted the closed flow.

Nach einer Weiterbildung der Erfindung ist eine Sammelmulde vorgesehen, in der ein verschliessbarer Ablauf und eine Öffnung für das Überlaufrohr angeordnet sind. Dadurch ist eine einfache Konstruktion und eine einfache Montage möglich. Nach einer Weiterbildung der Erfindung ist in dieser Sammelmulde zudem eine Öffnung für das kommunizierende Rohr angeordnet. According to a development of the invention, a collecting trough is provided, in which a closable drain and an opening for the overflow pipe are arranged. This makes it a simple construction and easy assembly possible. After further training the invention is also an opening in this trough arranged for the communicating pipe.

Die Überlauf- und Ablaufgarnitur 1 weist gemäss Figur 1 eine Sammelmulde 3 auf, die in an sich bekannter Weise gemäss Figur 3 an einem Boden 35 eines Sanitärkörpers 2, beispielsweise einer Badewanne, montiert ist. Über der Sammelmulde 3 ist ein Deckel 11 angeordnet, der eine Ablauföffnung 10, eine Öffnung 15 für ein Überlaufrohr 5 und eine Öffnung 14 für ein kommunizierendes Rohr 8 abdeckt. In Figur 1 ist der Deckel 11 aus zeichnerischen Gründen abgeschnitten. Der Deckel 11 schliesst die Sammelmulde 3 nicht ab, sondern bildet an seinem Rand eine hier nicht sichtbare Öffnung, durch die Wasser in die Sammelmulde 3 gelangt.According to FIG. 1, the overflow and waste set 1 has one Collection trough 3, which in a manner known per se according to FIG. 3 on a floor 35 of a sanitary body 2, for example one Bathtub, is mounted. There is a cover over the trough 3 11, which has a drain opening 10, an opening 15 for an overflow pipe 5 and an opening 14 for a communicating Pipe 8 covers. In Figure 1, the lid 11 is drawn Cut off reasons. The lid 11 closes the collecting trough 3 does not depict, but forms a here on its edge invisible opening through which water enters the collecting trough 3 arrives.

Die Ablauföffnung 10 ist gemäss Figur 4 mit einem an sich bekannten Ablaufventil 21 verschliessbar und führt in einen Sifon bzw. Geruchsverschluss 20 sowie in ein Ablaufrohr 9, das an eine hier nicht gezeigte Entsorgungsleitung anzuschliessen ist.The drain opening 10 is, according to FIG. 4, with a known one Drain valve 21 can be closed and leads into a siphon or odor trap 20 and in a drain pipe 9 which is connected to a Disposal line not shown here is to be connected.

Wie insbesondere die Figur 3 zeigt, ist das Überlaufrohr 5 verdeckt angeordnet und somit von aussen bei montiertem Sanitärkörper 2 in der Regel nicht sichtbar. Das Überlaufrohr 5 ist wie ersichtlich von unten an die Öffnung 15 angeschlossen und besitzt einen im Wesentlichen horizontalen Abschnitt 22, an den ein im Wesentlichen vertikal aufsteigender Abschnitt 36, ein Bogen 38 sowie ein absteigender Abschnitt 37 anschliessen. Am unteren Ende des absteigenden Abschnitts 37 ist ein Sifonbogen bzw. Geruchsverschluss 12 angeschlossen, der über ein Anschlussstück 17 ebenfalls in die oben erwähnte Entsorgungsleitung führt. Der aufsteigende Abschnitt 36 bildet gemäss Figur 2 einen Steigkanal 18, der an seinem oberen Ende über eine Überlaufkante 6 in einen Rücklaufkanal 19 führt, der durch den Abschnitt 37 gebildet wird.As FIG. 3 in particular shows, the overflow pipe 5 is covered arranged and thus from the outside with the sanitary unit installed 2 usually not visible. The overflow pipe 5 is like can be seen from below connected to the opening 15 and has a substantially horizontal portion 22 to which a substantially vertically ascending section 36, an arch 38 and a descending section 37. At the bottom At the end of the descending section 37 is a siphon arch or odor trap 12 connected via a connector 17 also in the disposal line mentioned above leads. The ascending section 36 forms one according to FIG Rising channel 18, which at its upper end via an overflow edge 6 leads into a return channel 19 which passes through section 37 is formed.

Im Wesentlichen parallel zum horizontalen Abschnitt 22 verläuft ein Rohrabschnitt 13 des kommunizierenden Rohres 8, der an die Öffnung 14 angeschlossen und mit einem vertikal ansteigenden Abschnitt 39 verbunden ist. Das kommunizierende Rohr 8 besitzt an einem oberen Ende eine Öffnung 16. Unterhalb dieser Öffnung 16 ist das kommunizierende Rohr 8 mit einem im Wesentlichen horizontalen Rohr 7 mit dem Bogen 38 verbunden. Das Rohr 7 bildet gemäss Figur 2 einen wesentlich horizontal verlaufenden Verbindungskanal 40, dessen Querschnitt wesentlich kleiner ist als derjenige des Steigkanals 18. Die Öffnung 16 ist wie ersichtlich über der Überlaufkante 16 und auch über dem Verbindungskanal 40 angeordnet, befindet sich jedoch gemäss Figur 3 unterhalb eines Randes 4 des Sanitärapparates 2. Die Öffnung 16 ist somit ebenfalls verdeckt angeordnet. Die Öffnung 16 befindet sich aber vorzugsweise unmittelbar unterhalb des Randes 4, wie die Figur 3 erkennen lässt.Runs essentially parallel to the horizontal section 22 a pipe section 13 of the communicating pipe 8, which to the Opening 14 connected and with a vertically rising section 39 is connected. The communicating tube 8 has an opening 16 at an upper end. Below this opening 16 is the communicating tube 8 with a substantially horizontal one Tube 7 connected to the bend 38. The tube 7 forms 2 shows a substantially horizontal connecting channel 40, the cross section of which is significantly smaller than that of the riser duct 18. The opening 16 can be seen over the overflow edge 16 and also over the connecting channel 40 arranged, but is according to Figure 3 below a Edge 4 of the sanitary apparatus 2. The opening 16 is thus also arranged hidden. The opening 16 is however preferably immediately below the edge 4, as in FIG. 3 reveals.

Nachfolgend wird die Arbeitsweise erfindungsgemässen Überlaufund Ablaufgarnitur näher erläutert.The mode of operation according to the invention is described below Drain fitting explained in more detail.

Die Figur 6 zeigt eine Badewanne 2, an der eine erfindungsgemässe Überlauf- und Ablaufgarnitur 1 angeschlossen ist und die mit einem Wasserzulauf 31, beispielsweise einem üblichen Wasserhahn mit Wasser 28 gefüllt werden kann. Ist die Badewanne 2 gemäss Figur 6 leer, so ist der Sifon 20 mit Wasser 23 und der Sifon 12 mit Wasser 26 gefüllt. Ebenfalls sind die Abschnitte 22 und 13 mit Wasser 24 bzw. 25 gefüllt.FIG. 6 shows a bathtub 2 on which one according to the invention Overflow and waste set 1 is connected and with a water inlet 31, for example a conventional water tap can be filled with water 28. Is the bathtub 2 in accordance with FIG. 6 empty, the siphon 20 with water 23 and the sifon 12 filled with water 26. Sections 22 and 13 are also filled with water 24 or 25.

Wird nun gemäss Figur 7 die Wanne 2 mit Wasser gefüllt, so bildet sich in der Badewanne 2 ein ansteigendes Wasserniveau 27. Die Ablauföffnung 10 ist hierbei selbstverständlich geschlossen. Da die Öffnungen 14 und 15 offen sind und der Deckel 11 wie erwähnt an seinem Rand einen Durchlass bildet, steigt das Wasser gleichzeitig in den beiden Abschnitten 36 und 39. Durch die Öffnung 16 kann dabei die Luft zwischen dem Wasser 24 und 26 entweichen. Im Abschnitt 36 bildet das Wasser ein Wasserniveau 30 und im Abschnitt 39 ein Wasserniveau 29. Die Niveaus 27, 29 und 30 befinden sich jeweils auf gleicher Höhe. Befindet sich das Niveau 30 auf der Höhe der Überlaufkante 6, so befindet sich das Niveau 29 unterhalb des Verbindungskanals 40 und das Niveau 27 unterhalb des Randes 4. Ist die Wasserzufuhr zur Badewanne 2 vergleichsweise gering, so bleibt das Niveau 27 auf der Höhe der Überlaufkante 6 und zufliessendes Wasser wird laufend über die Überlaufkante 6 abgeführt. Das überlaufende Wasser 32 gelangt gemäss Figur 8 in den Sifonbogen 12 und schliesslich in die Entsorgungsleitung.If, according to FIG. 7, the tub 2 is filled with water, it forms an increasing water level 27 in the bathtub 2. The drain opening 10 is of course closed. Since the openings 14 and 15 are open and the lid 11 as mentioned forms a passage at its edge, the water rises simultaneously in both sections 36 and 39. Through the opening 16 can escape the air between the water 24 and 26. In section 36, the water forms a water level 30 and in section 39 a water level 29. Levels 27, 29 and 30 are each at the same height. Is that Level 30 at the level of the overflow edge 6, that's how it is Level 29 below the connecting channel 40 and level 27 below the edge 4. Is the water supply to the bathtub 2 comparatively low, the level 27 remains at the level of Overflow edge 6 and inflowing water is continuously over the Overflow edge 6 discharged. The overflowing water 32 arrives 8 in the siphon elbow 12 and finally in the disposal line.

Wird der Wasserzulauf 31 weiter geöffnet und pro Zeiteinheit mehr Wasser eingeleitet, sodass die übliche Ablaufleistung des Überlaufrohres 5 kleiner ist als die Zufuhr, so steigt das Niveau 27 über die Höhe der Überlaufkante 6 und schliesslich über die Höhe des Verbindungskanals 40, wie dies in Figur 9 angedeutet ist. Entsprechend steigt das Niveau 29 im kommunizierenden Rohr 8. Durch das Ansteigen des Niveaus 30 wird der Bogen 38 vollständig mit Wasser gefüllt. Der Querschnitt des Überlaufrohres 5 ist nun so dimensioniert, dass sich im Überlaufrohr 5 eine geschlossene Wasserströmung bildet. Eine geschlossene Strömung 34 bildet sich dann, wenn im Rücklaufkanal 19 der Volumenstrom so gross ist, dass er nach der Überlaufkante 6 den ganzen Querschnitt des Rücklaufkanals 19 abschliesst und keine Luft nachströmen kann. Vorzugsweise ist hierzu der Querschnitt des Kanals 19 kleiner als derjenige des Kanals 18. Hat sich eine solche geschlossene Wasserströmung 34 gebildet, so wird die Wassergeschwindigkeit im Kanal 19 wesentlich erhöht und damit entsprechend die Abfuhrleistung verbessert. Nach der Bildung der geschlossenen Wasserströmung 34 wird somit aus der Badewanne 2 mehr Wasser als vorher abgesaugt. Über den Verbindungskanal 40 wird durch die geschlossene Strömung 34 ebenfalls Wasser aus dem kommunizierenden Rohr 8 abgeführt. Das Niveau 29 und auch das Niveau 27 sinken somit vergleichsweise schnell. Die Leistung der geschlossenen Wasserströmung 34 ist so bemessen, dass sie höher ist als die maximal zulässige Zuflussmenge. Diese maximal zulässige Zuflussmenge beträgt bei sanitären Apparaten in der Regel 0,5 bis 0,6 l/Sek. In den meisten Ländern bestehen entsprechende Vorschriften. Das Überlaufrohr 5 ist somit so dimensioniert, dass nach der Bildung der geschlossenen Wasserströmung 34 pro Sekunde mehr als beispielsweise 0,5 bis 0,6 l/Sek. abgeführt wird. Auch bei maximalem Zufluss sinkt somit das Niveau 29, nach dem sich eine geschlossene Wasserströmung 34 gebildet hat. Sinkt nun das Niveau 29 unter die Höhe des Verbindungskanals 40, so strömt durch die Öffnung 16 Luft durch den Verbindungskanal 40 in den Bogen 38, wie dies in Figur 10 mit dem Pfeil 33 angedeutet ist. Dadurch wird die geschlossene Wasserströmung 34 unterbrochen und das Niveau 27 fällt auf die Höhe der Überlaufkante 6. Bleibt die Zuflussmenge weiterhin hoch, so steigt das Niveau 27 wieder an und der oben geschilderte Vorgang mit der Bildung der geschlossenen Wasserströmung 34 wiederholt sich. Wird die Wasserzufuhr abgestellt oder wesentlich gedrosselt, so bleibt das Niveau 27 gemäss Figur 10 stabil auf der Höhe der Überlaufkante 6.The water inlet 31 is opened further and per time unit more water is introduced, so that the usual drainage rate of the Overflow pipe 5 is smaller than the feed, the level rises 27 over the height of the overflow edge 6 and finally over the height of the connecting channel 40, as indicated in Figure 9 is. Accordingly, the level 29 in communicating rises Pipe 8. As the level 30 rises, the bend becomes 38 completely filled with water. The cross section of the overflow pipe 5 is now dimensioned such that a in the overflow pipe 5 forms a closed water flow. A closed flow 34 is formed when the volume flow in the return duct 19 is so large that after the overflow edge 6 it is the whole Cross section of the return channel 19 closes and no air can flow. For this purpose, the cross section of the Channel 19 is smaller than that of channel 18. Has one such closed water flow 34 is formed, the water speed in channel 19 significantly increased and accordingly the discharge performance improved. After the formation of the closed water flow 34 is thus from the bathtub 2nd sucked out more water than before. Via the connecting channel 40 is also water from the closed flow 34 communicating pipe 8 discharged. Level 29 and that too Level 27 thus sink comparatively quickly. The performance of the closed water flow 34 is sized to be higher is the maximum allowable inflow amount. This maximum allowable The inflow amount for sanitary appliances is usually 0.5 to 0.6 l / sec. Corresponding ones exist in most countries Regulations. The overflow pipe 5 is thus dimensioned that after the formation of the closed water flow 34 per Second more than, for example, 0.5 to 0.6 l / sec. dissipated becomes. Even with the maximum inflow, the level 29 thus decreases which has formed a closed water flow 34. Sinks now the level 29 below the height of the connecting channel 40, see above air flows through the opening 16 through the connecting duct 40 in the sheet 38, as indicated by the arrow 33 in FIG. 10 is. As a result, the closed water flow 34 is interrupted and level 27 drops to the level of the overflow edge 6. If the inflow remains high, the level rises 27 again and the process described above with the formation the closed water flow 34 is repeated. Becomes the water supply turned off or throttled significantly, so level 27 remains stable at the level of FIG Overflow edge 6.

Um die Badewanne 2 zu entleeren, wird das Ablaufventil 21 geöffnet. Das Wasser läuft über den Sifonbogen 12 ab und gelangt in die oben genannte Entsorgungsleitung. Schliesslich wird wieder der in Figur 6 gezeigte Zustand erreicht.In order to empty the bathtub 2, the drain valve 21 is opened. The water runs over the siphon bend 12 and enters the above-mentioned disposal line. Eventually, again the state shown in Figure 6 is reached.

Bei einer Überfüllung über die Überlaufkante 6 wird somit eine geschlossene Wasserströmung 34 gebildet, die eine vergleichsweise hohe Leistung besitzt und die auch bei maximalem Zufluss verhindert, dass die Badewanne 2 überläuft. Ein Überlaufen der Badewanne 2 könnte selbstverständlich auch mit einem Überlaufrohr 5 realisiert werden, das eine entsprechend weit dimensioniert Leitung besitzt. Ein solches Überlaufrohr würde aber entsprechend sehr viel Platz beanspruchen. Das Überlaufrohr 5 der erfindungsgemässen Überlauf- und Ablaufgarnitur kann aber mit einem Überlaufrohr 5 realisiert werden, das Kanäle 18 und 19 mit einem wesentlich kleineren Innendurchmesser aufweist. Auch bei maximal zulässigem Zufluss kann ein Überlaufen der Badewanne 2 oder eines anderen Sanitärapparates vermieden werden. In the event of an overfill over the overflow edge 6, one becomes closed water flow 34 formed, which is a comparatively has high performance and prevents even with maximum inflow, that the bathtub 2 overflows. An overflow of the bathtub 2 could of course also with an overflow pipe 5 can be realized, which is dimensioned accordingly wide Management. Such an overflow pipe would be appropriate take up a lot of space. The overflow pipe 5 of the Overflow and waste set according to the invention can, however, with an overflow pipe 5 can be realized, the channels 18 and 19 with has a much smaller inner diameter. Also at maximum permissible inflow can overflow the bathtub 2 or other sanitary equipment can be avoided.
