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.The invention relates to a drain valve for a cistern, in particular a toilet cistern, with a housing to be fastened to the bottom of the cistern, in which a float is arranged with an air chamber open at the bottom, which float is attached to a closing member which can be raised in the housing, and an upper ceiling wall and has a side wall.

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. In these, the buoyancy of the float after a flush is triggered by the air present in an air chamber of the float. Such drain valves can be designed so that the purging is interrupted prematurely is possible. Drain valves are also known which allow a so-called two-stage flushing. When you press a button, the cistern is automatically emptied completely. When you press another button, only part of the amount of flushing water in the cistern, for example 6 liters, is automatically dispensed. Practice has shown that such a two-stage rinse with precisely set amounts of rinse water is superior to a rinse interruption to be determined by the user himself. With two-stage rinsing, optimum savings in rinsing water are possible if the small amount of rinsing water is always exactly the same for small rinses.

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 air can escape from the float in the case of small flushes when using generic drain valves and water can thus enter the float from below. As a result, the buoyancy of the float and thereby the amount of flushing water can change in an uncontrolled manner. The consequence of this is that with the small rinses either too much or too little water is released. The inventor has now set himself the task of creating a drain valve of the type mentioned, which works more precisely with small flushings and which is nevertheless not much more complex and 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. 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 object is achieved in a generic drain valve in that the side wall of the air chamber at a distance from the ceiling wall determined by the volume of the air has at least one vent opening. The solution is surprisingly simple, yet reliable. In the drain valve according to the invention, the float is filled with water from the bottom to the vent opening after each flush. The level of the water in the float and therefore the volume of the air chamber is always precisely determined. Accordingly, the buoyancy of the swimmer is always the same. The ventilation opening can be realized, for example, by a small hole, which does not cause any significant costs. The water layer in the float below the ventilation opening prevents air from escaping from the float during a small flush.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Beschreibung sowie der Zeichnung.Further advantageous features result from the dependent claims, the following description 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 will be explained in more detail with reference to the single figure, which shows a section through a drain valve according to the invention in a schematic representation.

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 detachably fastened in a cistern 1 in a known manner via a drain opening 3 on the cistern floor 2. In a valve housing 6, a valve tube 4 is mounted so that it can be raised with a float 7 fixedly attached to it. In the idle state shown, the opening 3 is closed by a valve plate 13 of the valve tube 4. If the valve tube 4 is raised by means of an actuating device 14 known per se, the drain opening 3 is opened and rinsing water 17 can flow through the window 19 of the housing 6 through the opening 3 into a toilet bowl (not shown here). The valve tube 4 is kept floating by the buoyancy of an air chamber 16 in the housing 6 until the desired amount of flushing water is dispensed.

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 flushing water, a closing weight 15 is arranged in a known manner on the valve tube 4, which loads the valve tube 4 when the flushing is small and brings it prematurely into the closed position. With such a small flush, the water level A of the completely filled cistern is lowered to level B. After a small flush, there is a residual water quantity of, for example, 3 liters in the cistern. In the event of a large flush, the valve tube 4 is not loaded by the closing weight 15 and this therefore remains raised until the cistern 1 is completely emptied.

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 side wall 9. In the lower region of the side wall 9, one or more ventilation openings 10 are provided at a certain distance from the top wall 8. These 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. As the drawing shows, the float 7 has a likewise cylindrical apron 11 below the ventilation openings 10. This extends to the lower edge 12, which defines the lower opening of the float 7.

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 a quantity of water 18 in the float 7, the level C of which is determined by the ventilation openings 10. This apron 11 is dimensioned such that no air can be drawn out of the chamber 16 of the float 7 with a small flush. The height of the apron 11 is, for example, 2 cm. Exact values can easily be determined in practical tests.

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 Oeffnungen 10 entweichen kann und damit das Wasser 18 in den Schwimmer 7 von unten eindringen kann.The ventilation openings 10 are dimensioned such that no air can escape from them when they are briefly closed during a small flush. This is ensured with a bore with a diameter of, for example, 2 to 5 mm. The ventilation openings 10 must be at least large enough that after a large flush, the air in the region of the apron 11 can escape through these openings 10 and thus the water 18 can penetrate into the float 7 from below.
