Abstract

Outlet valve in which the side wall (3) has a venting opening (10) arranged at a distance from the cover wall (8) determined by the volume of air. An apron (11) is fitted below the venting opening on the side wall. The venting opening is so dimensioned that after a large flushing action the air in the float (7) can escape during the period of filling-up to the venting opening (10). With a short time closure of the outlet valve during a small flushing action no air escapes via the venting opening.

Description

Die Erfindung betrifft ein Ablaufventil für einen Spülkasten, insbesondere WC-Spülkasten, mit einem am Spülkastenboden zu befestigenden Gehäuse, in dem ein Schwimmer mit einer unten offenen Luftkammer angeordnet ist, welcher Schwimmer an einem im Gehäuse anhebbar gelagerten Schliessorgan angebracht ist und eine obere Deckenwandung sowie eine Seitenwandung aufweist. Ein derartiges Ablaufventil ist aus der DE-U-93 11 189 bekannt.The invention relates to a drain valve for a cistern, especially toilet cistern, with one on the cistern floor to be attached housing in which a float with an air chamber open at the bottom, which Float on a locking device that is lifted in the housing is attached and an upper ceiling wall and a Has side wall. Such a drain valve is known from DE-U-93 11 189.

Ablaufventile dieser Art sind seit langem bekannt. Bei diesen ist der Auftrieb des Schwimmers nach einer Spülauslösung durch die in einer Luftkammer des Schwimmers vorhandene Luft gewährleistet. Solche Ablaufventile können so ausgebildet sein, dass eine vorzeitige Unterbrechung der Spülung möglich ist. Ebenfalls sind Ablaufventile bekannt, die eine sogenannte Zweistufenspülung erlauben. Bei der Betätigung einer Taste wird dann selbsttätig der Spülkasten vollständig entleert. Bei der Betätigung einer anderen Taste wird ebenfalls selbsttätig nur ein Teil der im Spülkasten vorhandenen Spülwassermenge, beispielsweise 6 Liter abgegeben. Die Praxis hat gezeigt, dass eine solche Zweistufenspülung mit genau eingestellten Spülwassermengen einer vom Benutzer selbst zu bestimmenden Spülunterbrechung überlegen ist. Bei der Zweistufenspülung ist eine optimale Einsparung an Spülwasser dann möglich, wenn die kleine Spülwassermenge bei kleinen Spülungen immer exakt gleich ist.Drain valves of this type have been known for a long time. With these is the buoyancy of the float after a flush has been triggered by the existing in an air chamber of the swimmer Air guaranteed. Such drain valves can be designed in this way be that an early interruption of the flushing is possible. Drain valves are also known allow a so-called two-stage rinse. When actuated the cistern is then automatically complete with a button emptied. When you press another key is also automatically only a part of the in the cistern existing flushing water volume, for example 6 liters. Practice has shown that such a two-stage rinse with precisely set amounts of rinse water from User to consider rinsing interruption to be determined is. With two-stage flushing, there is an optimal saving of rinse water possible if the small amount of rinse water is always exactly the same for small flushes.

Der Erfinder hat nun durch aufwendige Untersuchungen festgestellt, dass bei kleinen Spülungen bei Verwendung gattungsgemässer Ablaufventile aus dem Schwimmer Luft entweichen und dadurch Wasser von unten in den Schwimmer gelangen kann. Demzufolge kann sich der Auftrieb des Schwimmers und dadurch die Spülwassermenge unkontrolliert ändern. Die Folge davon ist, dass bei den kleinen Spülungen entweder zuviel oder zuwenig Wasser abgegeben wird. Der Erfinder hat sich nun die Aufgabe gestellt, ein Ablaufventil der genannten Gattung zu schaffen, das bei kleinen Spülungen genauer arbeitet und das dennoch nicht wesentlich aufwendiger und teurer in der Herstellung ist.The inventor has now determined through extensive investigations that with small flushes when using generic Drain valves escape from the air float and thereby get water into the float from below can. As a result, the buoyancy of the swimmer and thereby changing the flushing water quantity in an uncontrolled manner. The consequence of it is that with the small rinses either too much or too little water is released. The inventor has now set the task of a drain valve of the above Genre to create that more precisely with small flushing works and yet not much more complex and is more expensive to manufacture.

Die Aufgabe ist bei einem gattungsgemässen Ablaufventil dadurch gelöst, dass die Seitenwandung der Luftkammer in einem durch das Volumen der Luft bestimmten Abstand zur Dekkenwandung wenigstens eine Entlüftungsöffnung aufweist derart, daß bei gefülltem Spülkasten unterhalb der Entlüftungsöffnung eine Wasserschicht besteht, die verhindert, daß bei einer kleinen Spülung aus dem Schwimmer Luft abgesogen werden kann. Die Lösung ist überraschend einfach und dennoch funktionssicher. Beim erfindungsgemässen Ablaufventil wird nach jeder Spülung der Schwimmer von unten genau bis zur Entlüftungsöffnung mit Wasser gefüllt. Das Niveau des im Schwimmer vorhandenen Wassers und damit das Volumen der Luftkammer ist damit immer genau bestimmt. Entsprechend ist der Auftrieb des Schwimmers immer gleich. Die Entlüftungsöffnung kann beispielsweise durch eine kleine Bohrung realisiert werden, was keine nennenswerten Kosten verursacht. Die im Schwimmer unterhalb der Entlüftungsöffnung vorhandene Wasserschicht verhindert, dass bei einer kleinen Spülung aus dem Schwimmer Luft entweichen kann.The task is therefore in a generic drain valve solved that the side wall of the air chamber in one distance from the ceiling wall determined by the volume of air has at least one ventilation opening in such a way that when the cistern is full there is a layer of water below the ventilation opening which prevents air from being sucked out of the float during a small flush. The The solution is surprisingly simple, yet reliable. In the drain valve according to the invention, after each Flush the float from the bottom to the vent filled with water. The level of the in the swimmer existing water and thus the volume of the air chamber is always exactly determined. The buoyancy is corresponding always the same for the swimmer. The vent can be realized, for example, through a small hole which does not cause any significant costs. The in Float existing water layer below the vent prevents from running out with a little rinse air can escape from the swimmer.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Beschreibung sowie der Zeichnung.Further advantageous features result from the dependent ones Claims, the description below and the drawing.

Ein Ausführungsbeispiel der Erfindung wird anhand der einzigen Figur, die in schematischer Darstellung einen Schnitt durch ein erfindugsgemässes Ablaufventil zeigt, näher erläutert.An embodiment of the invention is based on the only Figure, which is a schematic representation of a section shows by a drain valve according to the invention, explained in more detail.

Das gezeigte Ablaufventil 5 ist in bekannter Weise in einem Spülkasten 1 über einer Ablauföffnung 3 am Spülkastenboden 2 lösbar befestigt. In einem Ventilgehäuse 6 ist ein Ventilrohr 4 mit einem an diesem fest angebrachten Schwimmer 7 anhebbar gelagert. Im gezeigten Ruhezustand ist die Oeffnung 3 durch einen Ventilteller 13 des Ventilrohres 4 verschlossen. Wird das Ventilrohr 4 mittels einer an sich bekannten Betätigungsvorrichtung 14 angehoben, so wird die Ablauföffnung 3 geöffnet und Spülwasser 17 kann durch Fenster 19 des Gehäuses 6 durch die Oeffnung 3 in eine hier nicht gezeigte WC-Schüssel abfliessen. Das Ventilrohr 4 wird durch den Auftrieb einer Luftkammer 16 im Gehäuse 6 schwebend gehalten, bis die gewünschte Spülwassermenge abgegeben ist.The drain valve 5 shown is in a known manner in one Cistern 1 over a drain opening 3 on the cistern floor 2 releasably attached. A valve tube is in a valve housing 6 4 with a float 7 firmly attached to it stored liftable. The opening is in the idle state shown 3 closed by a valve plate 13 of the valve tube 4. If the valve tube 4 by means of a known Actuator 14 raised, the Drain opening 3 opened and rinsing water 17 can through the window 19 of the housing 6 through the opening 3 in one here Drain the toilet bowl, not shown. The valve tube 4 is caused by the buoyancy of an air chamber 16 in the housing 6 kept floating until the desired amount of rinse water is dispensed is.

Zum Auslösen einer kleinen Spülwassermenge ist in bekannter Weise am Ventilrohr 4 ein Schliessgewicht 15 angeordnet, das bei einer kleinen Spülung das Ventilrohr 4 belastet und vorzeitig in die Schliessstellung bringt. Bei einer solchen kleinen Spülung wird das Wasserniveau A des vollständig gefüllten Spülkastens bis zum Niveau B abgesenkt. Im Spülkasten verbleibt nach einer kleinen Spülung eine Restwassermenge von beispielsweise 3 Liter. Bei einer grossen Spülung wird das Ventilrohr 4 durch das Schliessgewicht 15 nicht belastet und dieses verbleibt somit bis zur vollständigen Entleerung des Spülkastens 1 angehoben.To trigger a small amount of rinse water is known in A closing weight 15 is arranged on the valve tube 4, that loads the valve tube 4 with a small flush and brings it into the closed position prematurely. With one small rinse, the water level A of the completely filled Cistern lowered to level B. In the cistern after a small rinse there is a residual amount of water of, for example, 3 liters. With a large flush the valve tube 4 is not by the closing weight 15 charged and this remains until the complete Emptying the cistern 1 raised.

Der Schwimmer 7 hat die Form eines umgekehrtes Bechers und besitzt eine Deckenwandung 8 sowie eine etwa zylinderförmige Seitenwandung 9. Im unteren Bereich der Seitenwandung 9 sind in einem bestimmten Abstand zur Deckenwandung 8 eine oder mehrere Entlüftungsöffnungen 10 angebracht. Diese Oeffnungen 10 sind vergleichsweise klein und besitzen vorzugsweise einen Durchmesser von wenigen Millimetern, beispielsweise 2 mm. Die Oeffnungen 10 können auch schmale Schlitze sein oder andere Formen aufweisen. Wie die Zeichnung zeigt, besitzt der Schwimmer 7 unterhalb der Entlüftungsöffnungen 10 eine ebenfalls zylindrische Schürze 11. Diese reicht bis zum unteren Rand 12, welcher die untere Oeffnung des Schwimmers 7 definiert.The float 7 has the shape of an inverted cup and has a top wall 8 and an approximately cylindrical one Side wall 9. In the lower area of the side wall 9 are at a certain distance from the ceiling 8 or more ventilation openings 10 attached. This Openings 10 are comparatively small and preferably have a diameter of a few millimeters, for example 2 mm. The openings 10 can also be narrow Be slots or have other shapes. Like the drawing shows, the float 7 has below the ventilation openings 10 a likewise cylindrical apron 11. This extends to the lower edge 12, which is the lower Opening of the float 7 defined.

In der Ruhestellung befindet sich im Schwimmer 7 eine Wassermenge 18, deren Niveau C durch die Entlüftungsöffnungen 10 bestimmt ist. Diese Schürze 11 ist so dimensioniert, dass bei einer kleinen Spülung keine Luft aus der Kammer 16 des Schwimmers 7 abgesogen werden kann. Die Höhe der Schürze 11 beträgt beispielsweise 2 cm. Genaue Werte können in praktischen Versuchen ohne weiteres ermittelt werden.In the rest position there is an amount of water in the float 7 18, whose level C through the vents 10 is determined. This apron 11 is dimensioned that with a small purge there is no air from the chamber 16 the float 7 can be sucked off. The height of the apron 11 is 2 cm, for example. Exact values can be found in practical tests can be easily determined.

Die Entlüftungsöffnungen 10 sind so dimensioniert, dass aus diesen bei kurzzeitigem Schliessen während einer kleinen Spülung keine Luft entweichen kann. Dies ist bei einer Bohrung mit einem Durchmesser von beispielsweise 2 bis 5 mm gewährleistet. Die Entlüftungsöffnungen 10 müssen wenigstens so gross sein, dass nach einer grossen Spülung die Luft im Bereich der Schürze 11 durch diese OeTfnungen 10 entweichen kann und damit das Wasser 18 in den Schwimmer 7 von unten eindringen kann.The ventilation openings 10 are dimensioned such that this when closing briefly during a small one Flushing no air can escape. This is with a hole with a diameter of, for example, 2 to 5 mm guaranteed. The ventilation openings 10 must at least be so big that after a big rinse Air in the area of the apron 11 through these openings 10 can escape and thus the water 18 in the float 7th can penetrate from below.
