Description

Die Erfindung betrifft ein Ablaufventil für einen Spülkasten nach dem Oberbegriff des Anspruchs 1.The invention relates to a drain valve for a cistern according to the preamble of claim 1.

Ablaufventile dieser Art ermöglichen eine Zweistufenspülung. Diese ermöglicht eine Teilspülung mit einer Wassermenge, die wesentlich kleiner ist als die im Spülkasten vorhandene Wassermenge. Dadurch ist es möglich, den Wasserverbrauch bei Spülkästen wesentlich zu senken.Drain valves of this type allow a two-stage flush. This allows a partial flush with an amount of water that is much smaller than the amount of water in the cistern. This makes it possible to significantly reduce the water consumption in cisterns.

Ein Ablaufventil dieser Art ist beispielsweise aus der WO 02/059431 bekannt geworden. Bei diesem wird im Fall einer Teilspülung der Verschlusskörper mittels einer Klinke 36 nach unten abgestützt. Die Teilspülung wird unterbrochen, indem diese Klinke durch das Gewicht eines oberen Schwimmers verschwenkt und damit der Verschlusskörper freigegeben wird. Bei diesem ist jedoch nachteilig, dass es aus vergleichsweise vielen beweglichen Einzelteilen besteht und deshalb entsprechend teuer in der Herstellung sowie störanfällig ist.A drain valve of this kind is for example from the WO 02/059431 known. In this case, the closure body is supported by a pawl 36 down in the case of partial flushing. The partial flush is interrupted by this pawl pivoted by the weight of an upper float and thus the closure body is released. In this, however, is disadvantageous that it consists of comparatively many moving parts and therefore is correspondingly expensive to manufacture and prone to failure.

Die EP 1 428 945 offenbart ein Ablaufventil, bei dem für eine Teilspülung ein oberer Schwimmer vorgesehen ist, der mit einer am Ventilgehäuse gelagerten Klinke zusammenarbeitet.The EP 1 428 945 discloses a drain valve in which an upper float is provided for a partial flush, which cooperates with a valve housing mounted on the latch.

Der Erfindung liegt die Aufgabe zugrunde, ein Ablaufventil der genannten Art zu schaffen, das aus weniger Einzelteilen und kostengünstiger herstellbar ist. Das Ablaufventil soll trotzdem funktionssicher sein.The invention has for its object to provide a drain valve of the type mentioned, which is less expensive and cheaper to produce. The drain valve should still be reliable.

Die Aufgabe ist gemäss Anspruch 1 gelöst.The problem is solved according to claim 1.

Durch die genannte direkte Kopplung des Einstellelementes mit dem Verschlusskörper ergibt sich eine überraschend wesentlich einfachere Konstruktion und auf bisher notwendige bewegliche Teile kann verzichtet werden.By said direct coupling of the adjustment with the closure body results in a surprisingly much simpler design and previously required moving parts can be omitted.

Das Einstellelement weist einen unteren Anschlag auf, mit dem bei einer Teilspülung der Verschlusskörper mit dem oberen Schwimmer gekoppelt wird. Ein solcher Anschlag kann sehr einfach und kostengünstig, beispielsweise durch eine Verdickung des unteren Endes des Einstellelementes realisiert werden.The adjusting element has a lower stop, with which the closure body is coupled to the upper float in a partial flush. Such a stop can be realized very easily and inexpensively, for example, by a thickening of the lower end of the adjustment.

Nach einer Weiterbildung der Erfindung ist vorgesehen, dass der untere Schwimmer Mittel für eine Hubbegrenzung aufweist. Eine solche Hubbegrenzung kann in besonders einfacher Weise insbesondere durch eine Nase am unteren Schwimmer realisiert werden, welche mit einer Schulter an einer Kulisse des Verschlussrohres zusammenarbeitet.According to a development of the invention, it is provided that the lower float has means for a stroke limitation. Such a stroke limitation can be realized in a particularly simple manner, in particular by a nose on the lower float, which cooperates with a shoulder on a backdrop of the closure tube.

Nach der Erfindung ist vorgesehen, dass der Verschlusskörper am Einstellelement hochgleiten kann, ohne dass hierbei der obere Schwimmer wirksam wird. Dies wird dies durch einen Toleranzbereich am unteren Ende des Einstellelementes realisiert.According to the invention, it is provided that the closure body can slide up on the adjusting element, without the upper float becoming effective. This is realized by a tolerance range at the lower end of the adjustment.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Beschreibung sowie der Zeichnung.Further advantageous features emerge from the dependent claims, the following description and the drawings.

An embodiment of the invention will be explained in more detail with reference to the drawing. Show it:

Die Figur 1 zeigt einen Spülkasten 13, in dem ein Ablaufventil 1 montiert ist. Das Ablaufventil 1 besitzt ein Gehäuse 2, das an einem unteren Ende einen Stutzen 21 besitzt, der in bekannter Weise am Boden 22a eines Kastenkörpers 22 befestigt ist und der eine Auslauföffnung 3 mit einem Ventilsitz 4 bildet. Der Ventilsitz 4 arbeitet mit einem Verschlusskörper 5 zusammen, der als Ventilrohr ausgebildet ist und der mit einem Zuggestänge 14 zur Auslösung einer Spülung anhebbar ist. Das Zuggestänge 14 ist an einer Zweimengenbetätigungsvorrichtung 7 angeordnet und greift wie ersichtlich am Verschlusskörper 5 an. Die Zweimengenbetätigungsvorrichtung 7 weist beispielsweise Tasten 12 und Drücker 15 auf. Eine solche geeignete Betätigung ist beispielsweise aus der WO 01/46528 des Anmelders bekannt geworden. Mit dieser sind zwei unterschiedliche Hubbewegungen möglich. Bei einem ersten Hub für eine Teilspülung wird der Verschlusskörper 5 weniger hoch angehoben als bei der Auslösung einer Vollspülung. Entsprechend wird bei einer Teilspülung ein zweiarmiger Hebel 14a des Zuggestänges 14 um einen kleineren Winkel verschwenkt als im Fall einer Vollspülung.The FIG. 1 shows a cistern 13, in which a drain valve 1 is mounted. The drain valve 1 has a housing 2 which has at a lower end a nozzle 21 which is fixed in a known manner to the bottom 22 a of a box body 22 and which forms an outlet opening 3 with a valve seat 4. The valve seat 4 cooperates with a closure body 5, which is designed as a valve tube and which can be raised with a pull rod 14 for triggering a flushing. The pull rod 14 is arranged on a dual-quantity actuation device 7 and acts as shown on the closure body 5. The Zweimengenbetätigungsvorrichtung 7 has, for example, buttons 12 and pushers 15. Such a suitable operation is for example from the WO 01/46528 have become known to the applicant. With this two different strokes are possible. In a first stroke for a partial flush of the closure body 5 is raised less high than when triggering a full flush. Accordingly, in a partial flushing a two-armed lever 14a of the pull rod 14 is pivoted by a smaller angle than in the case of a full flush.

In der Figur 1 ist der Kastenkörper 22 mit Spülwasser 17 gefüllt. Die Wasseroberfläche 18 befindet sich hierbei unterhalb einer Überlauföffnung 5a des Verschlusskörpers 15. Die Wassermenge, die im Spülkasten 13 vorhanden ist, beträgt beispielsweise 9 oder 6 Liter.In the FIG. 1 the box body 22 is filled with rinse water 17. The water surface 18 is in this case below an overflow opening 5a of the closure body 15. The amount of water that is present in the cistern 13, for example, 9 or 6 liters.

Der Verschlusskörper 5 besitzt im Bereich eines unteren Endes 6 einen angeformten Steg 19, der wie ersichtlich radial vorragt und der für ein Einstellelement 10 ein Lagerteil bzw. Kupplungsteil bildet. Der Steg 19 besitzt einen Durchgang 19a, in den das Einstellelement 10 mit einem Toleranzbereich 10d hindurchragt. Am unteren Ende des Toleranzbereiches 10d ist ein Anschlag 10b angeordnet, der hier als Verdickung ausgebildet ist. Über dem Toleranzbereich 10d weist das Einstellelement 10 ein Gewinde 10c auf, in das ein oberer Schwimmer 8 eingeschraubt ist. Durch Drehen des Einstellelementes 10 kann der obere Schwimmer 8 stufenlos in seiner Höhe verstellt werden. Das Einstellelement 10 besitzt zudem ein oberes Ende 10a, das in ein Führungselement 16 verschieblich hineinragt. Das Einstellelement 10 ist wie ersichtlich stabförmig ausgebildet und dient dazu, bei einer Teilspülung den oberen Schwimmer 8 mit dem Verschlusskörper 5 zu koppeln.The closure body 5 has in the region of a lower end 6 an integrally formed web 19 which, as can be seen, protrudes radially and forms a bearing part or coupling part for an adjusting element 10. The web 19 has a passage 19a into which the adjusting element 10 protrudes with a tolerance range 10d. At the lower end of the tolerance range 10d, a stop 10b is arranged, here as a thickening is trained. Above the tolerance range 10d, the adjusting element 10 has a thread 10c into which an upper float 8 is screwed. By turning the adjusting element 10, the upper float 8 can be adjusted continuously in height. The adjusting member 10 also has an upper end 10a, which projects into a guide member 16 slidably. As can be seen, the adjusting element 10 is rod-shaped and serves to couple the upper float 8 to the closure body 5 during a partial flushing.

Die Verbindung zwischen dem Einstellelement 10 und dem Steg 19 bzw. dem Verschlusskörper 5 ist jedoch entsprechend dem Toleranzbereich 10d lose.However, the connection between the adjusting element 10 and the web 19 or the closure body 5 is loose according to the tolerance range 10d.

Am Gehäuse 2 ist ein unterer Schwimmer 9 schwenkbar gelagert. Die Lagerung des unteren Schwimmers 9 am Gehäuse 2 erfolgt mit einer am Gehäuse 2 befestigten Schwenkachse 9b.On the housing 2, a lower float 9 is pivotally mounted. The storage of the lower float 9 on the housing 2 takes place with a housing 2 attached to the pivot axis 9b.

An einem oberen Ende des unteren Schwimmers 9 ist eine Nase 9a angeformt, die mit einer am Verschlusskörper 5 angeformten Kulisse 20 zusammenarbeitet. Diese Kulisse 20 besitzt einen Anschlag 20a, der ebenfalls als seitlich vorspringende Nase oder Schulter ausgebildet ist. Der Anschlag 20a hat eine doppelte Funktion. Im einen Fall begrenzt der Anschlag 20a den Hub des Verschlusskörpers 5 und im anderen Fall wird der Verschlusskörper 5 am unteren Schwimmer 9 abgestützt.At an upper end of the lower float 9, a nose 9a is formed, which cooperates with a molded-on closure body 5 setting 20. This gate 20 has a stop 20a, which is also designed as a laterally projecting nose or shoulder. The stopper 20a has a dual function. In one case, the stop 20a limits the stroke of the closure body 5 and in the other case, the closure body 5 is supported on the lower float 9.

Nachfolgend wird die Wirkungsweise des erfindungsgemässen Ablaufventils näher erläutert.The operation of the inventive drain valve will be explained in more detail.

Zur Auslösung einer Teilspülung wird durch Drücken der entsprechenden Tasten 12 der Verschlusskörper 5 in die in Figur 2 gezeigte Stellung angehoben. Durch den Auftrieb des oberen Schwimmers 8 wird das Einstellelement 10 ebenfalls angehoben, bis das untere Ende 10b unten am Steg 19 anliegt. Ein weiterer Auftrieb des Verschlusskörpers 5 wird durch den unteren Schwimmer 9 verhindert, welcher mit der Nase 9a oben auf dem Anschlag 20a anliegt. Die Figur 2 zeigt das Ablaufventil 1 unmittelbar nach Auslösung der Teilspülung. Durch den Auftrieb des oberen Schwimmers 8 wird der Verschlusskörper 5 in der in Figur 2 gezeigten Stellung gehalten. Da der Verschlusskörper 5 vom Ventilsitz 4 abgehoben ist, ist das Ventil offen und Wasser 17 strömt durch die Öffnung 3 in eine hier nicht gezeigte WC-Schüssel. Entsprechend sinkt die Wasseroberfläche 18. Befindet sich nun die Wasseroberfläche 18 unterhalb des oberen Schwimmers 8, so fällt der Auftrieb durch diesen oberen Schwimmer 8 weg und der Verschlusskörper 5 fällt auf den Ventilsitz 4. Das Ablaufventil 1 ist damit geschlossen. Da der Kastenkörper 22 nur teilweise entleert ist, befindet sich im Kastenkörper 22 noch Wasser 17, beispielsweise 3 oder 6 Liter. Über ein hier nicht gezeigtes an sich bekanntes Einlaufventil wird nun der Kastenkörper 22 wieder gefüllt, bis das in Figur 1 gezeigte Wasserniveau erreicht ist.To trigger a partial flush is by pressing the corresponding keys 12 of the closure body 5 in the in FIG. 2 raised position shown. By the buoyancy of the upper float 8, the adjusting member 10 is also raised until the lower end 10b rests on the web 19 below. Another buoyancy of the closure body 5 is prevented by the lower float 9, which rests with the nose 9a on top of the stop 20a. The FIG. 2 shows the drain valve 1 immediately after triggering the partial flush. By the buoyancy of the upper float 8, the closure body 5 in the in FIG. 2 shown position held. Since the closure body 5 is lifted off the valve seat 4, the valve is open and water 17 flows through the opening 3 in a toilet bowl, not shown here. Accordingly, the water surface 18 drops. Now is the water surface 18 below the upper float 8, the buoyancy drops through this upper float 8 and the closure body 5 falls on the valve seat 4. The drain valve 1 is closed. Since the box body 22 is only partially emptied, is still in the box body 22 17, for example, 3 or 6 liters. About a here not shown per se known inlet valve, the box body 22 is now filled again until the in FIG. 1 shown water level is reached.

Bei der Auslösung einer Vollspülung, bei welcher beispielsweise mit 6 oder 9 Litern gespült wird, wird der Verschlusskörper 5 in die in Figur 3 gezeigte Stellung angehoben. Der Hub ist hier etwas grösser als bei der Auslösung einer Teilspülung. Der obere Schwimmer 8 wird durch den Auftrieb mit dem Einstellelement 10 ebenfalls angehoben. Durch einen hier nicht gezeigten Anschlag des oberen Schwimmers 8 am Ventilgehäuse 2 ist die in Figur 3 gezeigte Stellung bestimmt. Beim Anheben des Verschlusskörpers 5 gleitet die Nase 9a an der Kulisse 20 entlang und erreicht schliesslich die in Figur 3 gezeigte Position, in welcher sich die Nase 9a unterhalb des Anschlags 20a befindet. Der Steg 19 befindet sich in dieser Stellung über dem unteren Ende 10b des Einstellelementes 10 und damit im oberen Teil des Toleranzbereiches 10d. Der Verschlusskörper 5 lastet nun auf dem unteren Schwimmer 9, während der obere Schwimmer 8 unwirksam ist. Das Ablaufventil 1 ist nun ebenfalls offen und Wasser 17 strömt durch die Öffnung 3 nach unten in die Klosettschüssel. Befindet sich die Wasseroberfläche 18 unterhalb des oberen Schwimmers 8, so lastet dieser auf dem Verschlusskörper 5, der jedoch in der offenen Stellung verharrt, da er am unteren Schwimmer 9 abgestützt ist. Die Wasseroberfläche 18 sinkt damit weiter nach unten und erreicht schliesslich den unteren Schwimmer 9. Sinkt die Wasseroberfläche 18 unter diesen unteren Schwimmer 9, so fällt auch hier der Auftrieb weg und der untere Schwimmer 9 schwenkt aufgrund seines Eigengewichtes in die in Figur 4 gezeigte Stellung. Der Verschlusskörper 5 ist nun nicht mehr unterstützt und fällt auf den Ventilsitz 4. Im Spülkasten 13 befindet sich lediglich noch eine Restmenge des Wassers 17. Das Ablaufventil 1 ist damit geschlossen. Wiederum wird automatisch über das hier nicht gezeigte Einlaufventil der Spülkasten 13 nachgefüllt. Schliesslich wird wieder die in Figur 1 gezeigte Stellung erreicht. Der Spülkasten 13 ist nun wieder für eine Teilspülung oder Vollspülung bereit.When triggering a full flush, in which, for example, flushed with 6 or 9 liters, the closure body 5 is in the in FIG. 3 raised position shown. The stroke is slightly larger here than when triggering a partial flush. The upper float 8 is also raised by the buoyancy with the adjusting element 10. By not shown here stop of the upper float 8 on the valve housing 2 which is in FIG. 3 shown position determined. When lifting the closure body 5, the nose 9a slides along the backdrop 20 and finally reaches the in FIG. 3 shown position in which the nose 9a is located below the stopper 20a. The web 19 is in this position above the lower end 10b of the adjusting element 10 and thus in the upper part of the tolerance range 10d. The closure body 5 now loads on the lower float 9, while the upper float 8 is ineffective. The drain valve 1 is now also open and water 17 flows through the opening 3 down into the toilet bowl. The water surface 18 is below the upper float 8, so it rests on the closure body 5, which remains in the open position, since it is supported on the lower float 9. The water surface 18 thus continues to fall down and finally reaches the lower float 9. If the water surface 18 sinks below this lower float 9, then the buoyancy drops away and the lower float 9 pivots due to its own weight in the in FIG. 4 shown position. The closure body 5 is now no longer supported and falls on the valve seat 4. The cistern 13 is still only a residual amount of water 17. The drain valve 1 is closed. Again, this will not be automatic about this shown inlet valve of the cistern 13 refilled. Finally, the in FIG. 1 reached shown position. The cistern 13 is now ready for a partial flush or full flush.
