Abstract

The overflow tube (13) has fittings (19) above the water level (7) which when the cistern body (2) is overloaded, the air inlet into the overflow tube at the overflow opening is reduced. By forming of a closed flow in the lumen of the overflow tube, the outflow power is increased. The fittings consist of a cover which is fixed at a specific distance above the overflow opening and is plate-shaped. The cover extends over an upper edge of the overflow tube. Between the upper edge of the overflow tube and the cover is a ring-shaped gap. The distance between the cover and an upper edge of the overflow tube is approximately 6mm.

Description

Die Erfindung betrifft einen Spülkasten mit einem Kastenkörper und einem Deckel, in denen eine Ablaufgarnitur, ein Einlaufventil und ein Ueberlaufrohr mit einer über dem Wasserspiegel angeordneten Ueberlauföffnung untergebracht sind.The invention relates to a cistern with a box body and a lid, in which a drain fitting, an inlet valve and an overflow pipe with an overflow opening arranged above the water level are accommodated.

Spülkästen dieser Art sind allgemein bekannt. Für diese bestehen Normen über die Ablaufleistung des Ueberlaufrohres, das in der Regel gleichzeitig der Ventilkörper des Ablaufventils ist. In einer solchen Norm ist gefordert, dass bei einer Zulaufleistung des Einlaufventils von 0,28 Liter pro Sekunde eine maximale Stauhöhe von 15 mm eingehalten wird und dass nach dem Unterbrechen des Wasserzuflusses innerhalb von 2 Sekunden die Stauhöhe auf mindestens 5 mm absinkt. Diese Norm wurde bisher durch entsprechende Dimensionierung des Querschnitts des Ueberlaufrohres erfüllt, wobei allerdings teilweise grosse Querschnitte von beispielsweise 46 mm erforderlich waren. Solche grossen Rohrquerschnitte sind beispielsweise aufgrund des Materialverbrauches und der Platzbeanspruchung nachteilig. Die Erfindung möchte hier Abhilfe schaffen.Cisterns of this type are generally known. For these there are standards on the drainage capacity of the overflow pipe, which is usually the valve body of the drain valve at the same time. Such a standard requires that a maximum damming height of 15 mm is maintained with an inlet capacity of the inlet valve of 0.28 liters per second and that after stopping the inflow of water the damming height drops to at least 5 mm within 2 seconds. This standard was previously met by appropriate dimensioning of the cross section of the overflow pipe, although large cross sections of, for example, 46 mm were sometimes required. Such large pipe cross sections are disadvantageous, for example, due to the material consumption and the space requirements. The invention seeks to remedy this.

Der erfindungsgemässe Spülkasten ist dadurch gekennzeichnet, dass das Ueberlaufrohr über dem Wasserspiegel Mittel aufweist, die bei einer Ueberfüllung des Kastenkörpers den Luftzutritt in das Ueberlaufrohr an der Ueberlauföffnung vermindert und durch die Bildung eines im wesentlichen geschlossenen Flusses im Lumen des Ueberlaufrohrs die Ablaufleistung erhöht wird. Versuche haben gezeigt, dass beim erfindungsgemässen Spülkasten mit einem Ueberlaufrohr, das eine innere Weite von 23 mm aufweist, die oben genannte Norm gewährleistet ist. Die Ablaufleistung ist hier im wesentlichen gleich gross wie bei einem vorbekannten Spülkasten mit einem Ueberlaufrohr, das eine innere Weite von 46 mm aufweist. Die genannten Mittel sind nach einer Weiterbildung der Erfindung durch einen Deckel realisiert, der in einem vorbestimmten Abstand über der Ueberlauföffnung angeordnet ist. Der Deckel ist gemäss einer Weiterbildung der Erfindung an einem Bügel befestigt, an dem ebenfalls das Ueberlaufrohr angebracht ist. Ist gemäss einer Weiterbildung der Erfindung der Deckel am Bügel angeformt, so ist der erfindungsgemässe Spülkasten ohne einen zusätzlichen Teil realisierbar.The cistern according to the invention is characterized in that the overflow pipe has means above the water level which, when the cistern body is overfilled, reduces the air access into the overflow pipe at the overflow opening and the drainage capacity is increased by the formation of an essentially closed flow in the lumen of the overflow pipe. Tests have shown that the above-mentioned standard is guaranteed in the cistern according to the invention with an overflow pipe which has an inner width of 23 mm. The drainage rate here is essentially the same as that of a previously known cistern with an overflow pipe which has an inner width of 46 mm. According to a development of the invention, the means mentioned are implemented by a cover which is arranged at a predetermined distance above the overflow opening. According to a development of the invention, the cover is attached to a bracket to which the overflow pipe is also attached. If, according to a development of the invention, the lid is formed on the bracket, the cistern according to the invention can be implemented without an additional part.

Die Figur 1 zeigt einen Spülkasten 1, der einen quaderförmigen Kastenkörper 2 besitzt, der beispielsweise auf eine hier nicht gezeigte Klosettschüssel aufgesetzt ist. Auf dem Kasten 2 ist ein abnehmbarer Deckel 3 angeordnet, in dem eine Betätigungstaste 17 gelagert ist. Am Kastenkörper 2 ist ein Einlaufventil bekannter Art befestigt, der ein nach unten ragendes Einlaufrohr 6 sowie einen Schwimmer 5 besitzt. Das üblicherweise als "Schwimmerventil" bezeichnete Einlaufventil 4 öffnet und schliesst in Abhängigkeit des Wasserspiegels 7.FIG. 1 shows a cistern 1 which has a cuboid-shaped cistern body 2 which is placed, for example, on a toilet bowl (not shown here). On the box 2, a removable cover 3 is arranged, in which an actuation button 17 is mounted. An inlet valve of a known type is attached to the box body 2 and has an inlet tube 6 projecting downwards and a float 5. This is commonly referred to as a "float valve" Inlet valve 4 opens and closes depending on the water level 7.

Der Boden 9 des Kastenkörpers 2 ist mit einem angeformten Ablaufstutzen 10 versehen, der mit einer an sich bekannten Ablaufgarnitur 11 ein Ablaufventil 12 bildet. Geöffnet wird das Ventil 12 durch Hinaufziehen eines zentralen Rohres 13, das gleichzeitig ein Ueberlaufrohr ist. Das Hinaufziehen des Rohres 13 erfolgt durch ein Verschwenken der Betätigungstaste 17, an der ein Arm 16 angebracht ist, welcher in einen Bügel 15 eingreift. Dieser Bügel 15 ist gemäss Figur 2 gabelförmig ausgebildet und am oberen Ende des Rohres 13 befestigt.The bottom 9 of the box body 2 is provided with an integrally formed drain connector 10 which forms a drain valve 12 with a drain fitting 11 known per se. The valve 12 is opened by pulling up a central tube 13, which is also an overflow tube. The tube 13 is pulled up by pivoting the actuation button 17, on which an arm 16 is attached, which engages in a bracket 15. This bracket 15 is fork-shaped according to Figure 2 and attached to the upper end of the tube 13.

Der in Figur 1 gezeigte Spülkasten 1 ist mit Spülwasser 8 gefüllt und für eine Spülung bereit. Der Wasserspiegel 7 befindet sich wie ersichtlich etwas unter der Ueberlauföffnung 18 des Rohres 13. Ueber dieser Oeffnung 18 ist ein Deckel 19 angeordnet, der gemäss Figur 2 am Bügel 15 befestigt und vorzugsweise angeformt ist. Der sich horizontal erstreckende Deckel 19 befindet sich in einem bestimmten Abstand C über der Oeffnung 18. Dieser Abstand C beträgt beispielsweise 6 mm. Wie insbesondere Figur 3 zeigt, erstreckt sich der Rand 20 des Deckels 19 über den Rand 22 des Rohres 13 hinaus. Zwischen dem Rand 22 und dem Deckel 19 besteht somit ein ringförmiger Spalt 23. Der Durchmesser B des kreisförmigen Deckels 19 beträgt vorzugsweise etwa 35 mm. Der Deckel 19 ist vorzugsweise geschlossen, dies ist jedoch nicht zwingend. Der Deckel 19 kann auch durch ein anderes Element ersetzt sein. Wesentlich ist, dass dieses die Oeffnung 18 teilweise abdeckt und die nachfolgend erläuterte Funktion erfüllt.The cistern 1 shown in Figure 1 is filled with rinse water 8 and ready for rinsing. As can be seen, the water level 7 is located somewhat below the overflow opening 18 of the tube 13. A cover 19 is arranged above this opening 18, which is fastened to the bracket 15 according to FIG. 2 and is preferably molded on. The horizontally extending cover 19 is located at a certain distance C above the opening 18. This distance C is, for example, 6 mm. As particularly shown in FIG. 3, the edge 20 of the cover 19 extends beyond the edge 22 of the tube 13. There is therefore an annular gap 23 between the edge 22 and the cover 19. The diameter B of the circular cover 19 is preferably approximately 35 mm. The lid 19 is preferably closed, but this is not mandatory. The lid 19 can also by a other element to be replaced. It is essential that this partially covers the opening 18 and fulfills the function explained below.

In der Figur 2 ist der Spülkasten beispielsweise infolge eines Defektes des Einlaufventils 4 überfüllt. Bei einer dauernden Zulaufleistung von 0,28 Liter pro Sekunde stellt sich die Stauhöhe A auf einen Wert von 15 mm ein. Das sich über den Rand 22 befindliche Spülwasser 8 gelangt durch den ringförmigen Spalt 23 unter den Deckel 19 und durch die Oeffnung 18 in das Lumen 21 des Rohres 13. Der Deckel 19 vermindert den Eintritt von Luft in das Lumen 21, derart, dass in diesem eine geschlossene Strömung besteht. Die Luftbeimischung im Lumen 21 ist gegenüber einem Rohr 13 ohne Deckel 19 somit weitgehend vermindert. Der Querschnitt D des Rohres 13 kann deshalb bei einer gegebenen Ablaufleistung kleiner gehalten werden als ein Spülkasten ohne Dekkel 19. Der Durchmesser D beträgt beim Ausführungsbeispiel 23 mm. Mit diesem Durchmesser kann bei der oben erwähnten Zulaufleistung eine maximale Stauhöhe A von 15 mm gehalten werden.In Figure 2, the cistern is overfilled, for example, due to a defect in the inlet valve 4. With a continuous feed rate of 0.28 liters per second, the accumulation height A is set to a value of 15 mm. The flushing water 8 located over the edge 22 passes through the annular gap 23 under the cover 19 and through the opening 18 into the lumen 21 of the tube 13. The cover 19 reduces the entry of air into the lumen 21, such that in this there is a closed flow. The air admixture in the lumen 21 is thus largely reduced compared to a tube 13 without a cover 19. The cross section D of the tube 13 can therefore be kept smaller than a cistern without a lid 19 for a given drainage capacity. The diameter D in the exemplary embodiment is 23 mm. With this diameter, a maximum accumulation height A of 15 mm can be maintained with the above-mentioned inflow capacity.

Wird der Zufluss von Spülwasser zum Spülkasten 1 unterbrochen, so vermindert sich die Stauhöhe A und der Wasserspiegel 7 sinkt schliesslich auf die Höhe des Randes 22. Infolge der erhöhten Ablaufleistung des Rohres 13 sinkt die Stauhöhe A gemäss Figur 4 nach einer Unterbrechung des Zuflusses zu einem Zeitpunkt t1 innerhalb von 2 Sekunden auf eine Höhe von 5 mm.If the inflow of rinsing water to the cistern 1 is interrupted, the damming height A decreases and the water level 7 finally drops to the height of the rim 22. As a result of the increased drainage capacity of the pipe 13, the damming height A decreases according to FIG. 4 after an interruption of the inflow to one Time t 1 to a height of 5 mm within 2 seconds.

Da gegenüber einem üblichen Spülkasten lediglich ein vergleichsweise einfacher zusätzlicher Teil 19 erforderlich ist, der beispielsweise aus Kunststoff hergestellt werden kann, fallen die zusätzlichen Herstellungskosten kaum ins Gewicht. Der Deckel 19 kann aber auch am Bügel 15 angeformt sein, so dass dann ein zusätzlicher Teil nicht vorhanden ist. Da die genannte Norm mit einem wesentlich schlankeren Rohr 13 erfüllbar ist, sind wesentliche Materialeinsparungen möglich und der freie Raum im Kastenkörper 2 kann entsprechend vergrössert werden.Since only a comparatively simple additional part 19, which can be made of plastic, for example, is required compared to a conventional cistern, the additional manufacturing costs are hardly significant. The cover 19 can also be integrally formed on the bracket 15, so that an additional part is then not available. Since the standard mentioned can be fulfilled with a much slimmer tube 13, significant material savings are possible and the free space in the box body 2 can be increased accordingly.

Das Ueberlaufrohr 13 ist beim Ausführungsbeispiel gleichzeitig ein Ventilrohr. Denkbar ist jedoch auch eine Ausführung, bei welcher das Ueberlaufrohr 13 kein Ventilkörper ist und fest am Boden 9 des Kastenkörpers 2 befestigt ist.The overflow pipe 13 is at the same time a valve pipe in the exemplary embodiment. However, an embodiment is also conceivable in which the overflow pipe 13 is not a valve body and is fixedly attached to the bottom 9 of the box body 2.
