Description

Die Erfindung betrifft ein Ablaufventil für einen Spülkasten, insbesondere WC-Spülkasten, bei dem in einem am Spülkastenboden zu befestigenden Gehäuse unterhalb einer sich in diesem horizontal erstreckenden Trennwand ein Schwimmer angeordnet ist, der an einem im Gehäuse verschiebbar gelagerten Schliessorgan angebracht ist, das an einem unteren Ende einen Dichtungskörper aufweist und das mit einem oberen Ende durch eine Oeffnung des Gehäuses aus diesem herausragt.The invention relates to a drain valve for a cistern, in particular toilet cistern, in which a float is arranged in a housing to be fastened to the bottom of the cistern below a partition wall which extends horizontally therein, which is attached to a closing element which is displaceably mounted in the housing and which is attached to a lower end has a sealing body and which protrudes with an upper end through an opening of the housing.

Ein Ablaufventil dieser Art ist beispielsweise aus der CH-A-386 351 bekannt. Das hier als Glocke bezeichnete Gehäuse ist in eine Oeffnung im Boden des Spülkastens eingesetzt und fest mit diesem verschraubt. Unterhalb einer Trennoder Deckwand der Glocke ist in einem unten offenen kreiszylindrischen Raum der Schwimmer untergebracht, der fest mit dem Ueberlaufrohr verbunden ist. Das Ueberlaufrohr bildet mit einem am unteren Ende angebrachten Ventilteller ein Verschlussorgan. Zum Auslösen einer Spülung wird der Verschlusskörper bzw. das Ueberlaufrohr mit dem daran befestigten Schwimmer angehoben, bis der Schwimmer an der genannten Trennwand unterseitig ansteht. Der Ventilteller des Verschlussorgans ist damit vom Ventilsitz abgehoben und somit das Ventil geöffnet. Durch seitliche Fenster in der Glocke strömt im Spülkasten vorhandenes Spülwasser beispielsweise in ein angeschlossenes Klosettbecken. Das Ablaufventil schliesst, sobald Luft durch einen Spalt zwischen dem Ueberlaufrohr und der Glocke unter die Trennwand gelangt. Die Montage dieses Ablaufventils ist nicht ganz einfach, da das Ventilrohr mit dem Ventilteller von unten in die Glocke eingesetzt werden muss. Dies ist besonders dann schwierig, wenn Mittel zur Regulierung der Sinkgeschwindigkeit in das Ablaufventil eingebaut werden sollen.A drain valve of this type is known for example from CH-A-386 351. The housing, referred to here as the bell, is inserted into an opening in the bottom of the cistern and screwed tight to it. Below a partition or top wall of the bell, the float is accommodated in a circular cylindrical space open at the bottom, which is firmly connected to the overflow pipe. The overflow pipe forms a closure element with a valve disk attached to the lower end. To initiate a flush, the closure body or the overflow pipe with the float attached to it is raised until the float is in contact with the partition mentioned on the underside. The valve plate of the closure member is thus lifted off the valve seat and the valve is thus opened. Flushing water in the cistern flows through side windows in the bell, for example, into a connected toilet bowl. The drain valve closes as soon as air gets under the partition through a gap between the overflow pipe and the bell. The installation of this drain valve is not very easy, since the valve tube with the valve plate has to be inserted into the bell from below. This is particularly difficult when means for regulating the rate of descent are to be built into the drain valve.

Der Erfindung liegt die Aufgabe zugrunde, ein Ablaufventil der genannten Gattung zu schaffen, das einfacher montierund demontierbar ist. Die Aufgabe ist bei einem gattungsgemässen Ablaufventil dadurch gelöst, dass die Trennwand mit einer unten an dieser angeordneten Kammer eine Einheit bildet, die von oben in das oben offene Gehäuse herausnehmbar eingesetzt ist. Beim erfindungsgemässen Ablaufventil kann das Gehäuse bzw. die Glocke ohne die genannte Einheit am Kastenboden befestigt werden. Anschliessend kann die Einheit mit dem Schliessorgan mit einer automatisierten Montageeinrichtung von oben in das Gehäuse eingesetzt werden. Bei einer Revision kann die Einheit mit dem Schliessorgan von oben aus dem Gehäuse herausgenommen werden, wobei das Gehäuse am Kastenboden verbleiben kann. Da die Trennwand beim erfindungsgemässen Ablaufventil nicht mehr fest am Gehäuse angebracht ist, kann diese durch Verwendung verschiedener Gehäuse bezüglich ihrer Höhe zum Ventilsitz in einfacher Weise angepasst werden. Für unterschiedliche Spülkästen kann somit die gleiche Einheit verwendet werden. Beispielsweise kann bei einem Unterputzspülkasten mit einer vergleichsweise hoch angeordneten Trennwand ein entsprechend hohes Gehäuse verwendet werden. Die Eiheit des erfindungsgemässen Ablaufventils ist somit sehr universell verwendbar.The invention has for its object to provide a drain valve of the type mentioned, which is easier to assemble and disassemble. The object is achieved in a generic drain valve in that the partition forms a unit with a chamber arranged at the bottom of the unit, which is removably inserted from above into the open housing. In the drain valve according to the invention, the housing or the bell can be on without the unit mentioned Box bottom to be attached. The unit with the locking device can then be inserted into the housing from above with an automated assembly device. In the event of a revision, the unit with the locking element can be removed from the housing from above, the housing remaining on the box bottom. Since the partition in the drain valve according to the invention is no longer firmly attached to the housing, its height can be easily adapted to the valve seat by using different housings. The same unit can therefore be used for different cisterns. For example, a correspondingly high housing can be used in a concealed cistern with a comparatively high partition. The unit of the drain valve according to the invention can thus be used very universally.

Die Figur 1 zeigt ein Ablaufventil 30, das ein rohrförmiges Gehäuse 1 aufweist, an dem ein Gewindestutzen 26 angeformt ist, der in eine Oeffnung 48 eines Spülkastenbodens 25 eingesetzt und mit einer Mutter 27 dicht an diesem festgeklemmt ist. In eine obere kreisrunde Oeffnung 43 (Figur 4) des Gehäuses 1 ist eine Einheit 10 eingesetzt, an der eine horizontale Trennwand 2 mit einer mittigen Oeffnung 33 angeformt ist. In die Oeffnung 33 ist von unten ein als Ueberlaufrohr ausgebildetes Schliessorgan 4 eingesetzt, das an seinem unteren Ende 5 einen Ventilteller 6 besitzt, der ein Dichtungskörper bildet und mit dem Ventilsitz 44 zusammenarbeitet. Am oberen Ende 7 des Schliessorgans 4 ist eine Lasche 34 angeformt, in die ein Hebel 35 einer hier nicht näher bezeichneten Betätigungsvorrichtung eingreift. Mit dieser Vorrichtung kann das Schliessorgan 4 angehoben und dadurch das Ventil geöffnet werden. Im Spülkasten vorhandenes Spülwasser 45 kann bei geöffnetem Ventil durch seitliche Fenster 28 des Gehäuses 1 und eine Oeffnung 46 des Stutzens 26 in eine hier nicht gezeigte WC-Schüssel abfliessen.1 shows a drain valve 30, which has a tubular housing 1, on which a threaded connector 26 is formed, which is inserted into an opening 48 of a cistern floor 25 and is tightly clamped to the latter by a nut 27. A unit 10 is inserted into an upper circular opening 43 (FIG. 4) of the housing 1, on which a horizontal partition 2 with a central opening 33 is formed. In the opening 33, a closing element 4 designed as an overflow pipe is inserted from below, which has a valve plate 6 at its lower end 5, which forms a sealing body and cooperates with the valve seat 44. At the upper end 7 of the locking member 4, a tab 34 is formed, in which a lever 35 of an actuating device, not shown here, engages. With this device, the closing member 4 can be raised, thereby opening the valve. Flushing water 45 present in the cistern can flow through a side window 28 of the housing 1 and an opening 46 of the nozzle 26 into a toilet bowl (not shown) when the valve is open.

Das Gehäuse 1 und die Einheit 10 sind mit einem separat hergestellten kreisförmigen Deckel 12 lösbar miteinander verbunden. Dazu ist am Deckel 12 unterseitig ein Rastring 36 angeformt, an dem zwei gegenüberliegende Rastzähne 37 der Einheit 10 von unten eingerastet sind. Diese Rastzähne 37 sind gemäss den Figuren 2 und 3 an einem oberen Rand 47 einer becherförmigen Wandung 11 angeformt. Ausnehmungen 38 seitlich, neben und unterhalb der Zähne 37 ermöglichen eine radiale Auslenkung beim Einrasten dieser Zähne. Die Einheit 10 ist am Ring 36 drehbar gelagert, wobei die Zähne 37 am Rastring 36 in Umfangsrichtung entlanggleiten können.The housing 1 and the unit 10 are detachably connected to one another with a separately produced circular cover 12. For this purpose, a locking ring 36 is formed on the underside of the cover 12, on which two opposite locking teeth 37 of the unit 10 are engaged from below. According to FIGS. 2 and 3, these locking teeth 37 are formed on an upper edge 47 of a cup-shaped wall 11. Recesses 38 on the side, next to and below the teeth 37 allow radial deflection when these teeth snap into place. The unit 10 is rotatably mounted on the ring 36, wherein the teeth 37 can slide along the locking ring 36 in the circumferential direction.

Der Deckel 12 besitzt zudem zwei gegenüberliegende Laschen 24, die sich gemäss Figur 8 am Rand des Deckels vertikal nach oben und nach unten erstrecken. Die Laschen 24 sind jeweils seitlich einer Oeffnung 49 des Deckels 12 angeformt. Der obere Bereich 47 der Laschen 24 bildet jeweils einen Griff, an dem die Laschen 24 in Richtung der Pfeile 50 elastisch verschwenkbar sind. Die an einem unteren Bereich 23 der Laschen 24 angeformten Rastzähne 51 werden hierbei nach aussen in Richtung der Pfeile 52 verschwenkt. Der Eingriff der Zähne 51 an einem weiteren umlaufenden Rastring 53 des Gehäuses 1 kann dämit gelöst und die Einheit 10 aus dem Gehäuse 1 herausgehoben oder auf diesem beliebig gedreht werden. Beim Aufsetzen des Deckels 12 auf das Gehäuse 1 rasten die Laschen 24 unter elastischer Auslenkung selbsttätig am Rastring 53 ein. Der Zusammenbau des Gehäuses 1 mit der Einheit 10 und dem Deckel 12 kann sehr einfach automatisch durch Zusammenstecken erfolgen. Eine Demontage ist ohne Werkzeuge sehr schnell und wiederholt möglich.The cover 12 also has two opposite tabs 24 which, according to FIG. 8, extend vertically upwards and downwards at the edge of the cover. The tabs 24 are each formed on the side of an opening 49 of the cover 12. The upper area 47 of the tabs 24 each forms a handle on which the tabs 24 in the direction of the arrows 50 are elastically pivotable. The locking teeth 51 formed on a lower region 23 of the tabs 24 are pivoted outwards in the direction of the arrows 52. The engagement of the teeth 51 on a further circumferential locking ring 53 of the housing 1 can thus be released and the unit 10 can be lifted out of the housing 1 or rotated as desired. When the cover 12 is placed on the housing 1, the tabs 24 automatically engage on the locking ring 53 with elastic deflection. The assembly of the housing 1 with the unit 10 and the lid 12 can be done very simply automatically by plugging together. Disassembly is possible very quickly and repeatedly without tools.

Das rohrförmige Schliessorgan 4 ist in der Oeffnung 8 des Deckels 12 durch vorstehende Führungsrippen 40 längsverschieblich geführt. Seitliche Schlitze 39 erlauben den Durchtritt von Luft vom Spülkasteninnenraum in einen ringförmigen Raum 59 der Einheit 10, sobald das Niveau 54 des Spülwassers 45 während eines Spülvorgangs unterhalb dieser Schlitze 39 abgesunken ist.The tubular closing member 4 is guided in the opening 8 of the cover 12 by means of projecting guide ribs 40 so as to be longitudinally displaceable. Lateral slots 39 allow air to pass from the interior of the cistern into an annular space 59 of the unit 10 as soon as the level 54 of the flushing water 45 has dropped below these slots 39 during a flushing process.

Damit zur Unterbrechung der Spülung die in die Kammer 59 eingedrungene Luft unterhalb die Trennwand 2 gelangen kann, sind gemäss Figur 11 über- und unterhalb der Trennwand 2 jeweils in der Wandung 11 sowie in einer unten anschliessenden rohrförmigen Wandung 55 jeweils wenigstens ein Durchbruch 20 bzw. 21 angeordnet. Die Luft kann vom Durchbruch 20 über den Durchbruch 21 unter die Trennwand 2 in eine Kammer 9 gelangen, wenn die Einheit 10 in eine Position gedreht ist, in der die Durchbrüche 20 und 21 im Bereich einer länglichen, sich vertikal erstreckenden Vertiefung 15 der Innenseite des Gehäuses 1 angeordnet ist. Die Vertiefung ist in Figur 5 gezeigt. In Figur 11 ist der Weg der Luft in die Kammer 9 mit dem Pfeil 56 angedeutet. Der Durchgang durch die Durchbrüche 20 und 21 sowie die Vertiefung 15 sind so dimensioniert, dass das Wasser im ringförmigen Raum 53 vergleichsweise langsam abfliesst und das Ventil erst dann schliesst, wenn Luft in die Kammer 9 eintritt und der Spülkasten im wesentlichen vollständig geleert ist. Wie ersichtlich erstreckt sich die Vertiefung 15 in vertikaler Richtung des Gehäuses 1 und ist überall etwa gleich tief und breit. Die Durchbrüche 20 und 21 bzw. die Trennwand 2 können somit auf beliebiger Höhe der Vertiefung 15 angeordnet sein, ohne dadurch die Sinkgeschwindigkeit des Schliessorgans 4 zu beeinflussen.In order to interrupt the purging, the air that has entered the chamber 59 can pass below the partition 2, according to FIG. 11 above and below the partition 2 in each case in the wall 11 and in a tubular wall 55 adjoining below, at least one opening 20 or 21 arranged. The air can pass from the opening 20 through the opening 21 under the partition 2 get into a chamber 9 when the unit 10 is rotated into a position in which the openings 20 and 21 are arranged in the region of an elongated, vertically extending recess 15 on the inside of the housing 1. The depression is shown in FIG. 5. The path of the air into the chamber 9 is indicated by the arrow 56 in FIG. The passage through the openings 20 and 21 and the depression 15 are dimensioned such that the water in the annular space 53 flows out comparatively slowly and the valve only closes when air enters the chamber 9 and the cistern is essentially completely emptied. As can be seen, the depression 15 extends in the vertical direction of the housing 1 and is approximately the same depth and width everywhere. The openings 20 and 21 or the partition 2 can thus be arranged at any height of the recess 15 without thereby influencing the sinking speed of the closing element 4.

Soll das Ablaufventil 30 zur Auslösung einer Teilspülung vor einer vollständigen Entleerung des Spülkastens schliessen, so wird gemäss Figur 10 die Einheit 10 in eine Drehstellung gedreht, in der ein Längsschlitz 22 der Einheit 10 mit einem Durchbruch 13 des Gehäuses 1 in Deckung ist. In dieser Drehstellung der Einheit 10 kann gemäss Figur 10 Luft in Richtung des Pfeiles 58 von der Aussenseite 57 des Gehäuses 1 durch den Durchbruch 13 und den Schlitz 22 ungehindert und direkt in die Kammer 9 gelangen. Der Durchtritt ist wesentlich breiter als beim Durchtritt in Richtung des Pfeiles 56, so dass die Kammer 9 sehr schnell mit Luft gefüllt wird, sobald die Oberfläche des Spülwassers 45 gemäss Figur 10 den Durchbruch 13 erreicht hat. Das Schliessorgan 4 schliesst das Ablaufventil dann vor der vollständigen Entleerung des Spülkastens. Bei der vollständigen-Spülung wird beispielsweise eine gesamte Spülwassermenge von 9 Liter und im anderen Fall lediglich eine Teilmenge von 6 Liter zur Spülung benutzt. Der Luftdurchtritt in Richtung des Pfeiles 58 ist auch dann gewährleistet, wenn der Schlitz 22 höher angeordnet ist.If the drain valve 30 is to close in order to trigger a partial flush before the cistern is completely emptied, the unit 10 is rotated according to FIG. 10 into a rotational position in which a longitudinal slot 22 of the unit 10 is in register with an opening 13 in the housing 1. In this rotational position of the unit 10, according to FIG. 10, air can pass unhindered and directly into the chamber 9 from the outside 57 of the housing 1 through the opening 13 and the slot 22 in the direction of the arrow 58. The passage is much wider than when passing in the direction of arrow 56, so that the chamber 9 very quickly is filled with air as soon as the surface of the rinsing water 45 has reached the opening 13 according to FIG. 10. The closing element 4 then closes the drain valve before the cistern is completely emptied. In the case of complete rinsing, for example, a total amount of rinsing water of 9 liters and in the other case only a partial amount of 6 liters is used for rinsing. The passage of air in the direction of arrow 58 is also ensured if the slot 22 is arranged higher.

Die Einheit 10 kann bezüglich des Gehäuses 1 in die gewünschte Drehstellung gedreht werden, indem das Schliessorgan 4 an seinem oberen Ende 7 angehoben wird, bis ein an einer oberen Wandung 29 (Figur 1) des Schwimmers 3 angeordneter Vorsprung 31 einen Vorsprung 32 an der Unterseite der Trennwand 2 aufnimmt und anschliessend das Schliessorgan 4 um seine Längsachse gedreht wird. Die Einheit 10 wird damit mitgenommen und in gleichem Sinn gedreht. Das Schliessorgan 4 wird dazu an seinem oberen Ende 7 entsprechend angehoben und gedreht. Die Verstellung ist damit sehr einfach und besonders bei schmalen und hohen Spülkästen, beispielsweise bei Unterputzspülkästen sehr bedienungsfreundlich, da nicht tief in den Spülkasten gegriffen werden muss.The unit 10 can be rotated with respect to the housing 1 into the desired rotational position by lifting the closing member 4 at its upper end 7 until a projection 31 arranged on an upper wall 29 (FIG. 1) of the float 3 has a projection 32 on the underside the partition 2 receives and then the closing member 4 is rotated about its longitudinal axis. The unit 10 is thus taken along and rotated in the same sense. The closing member 4 is accordingly raised and rotated at its upper end 7. The adjustment is therefore very simple and, particularly in the case of narrow and tall cisterns, for example in concealed cisterns, is very user-friendly since there is no need to reach deep into the cistern.

Die genannten beiden Drehpositionen sind durch Anschlagnokken 17 am unteren Rand der Einheit 10 und durch Auflagenokken 16 an der Innenseite 14 des Gehäuses 1 bestimmt. Zwischen zwei Anschlagnocken 17 ist in der Aussenseite 18 der Einheit 10 jeweils eine umlaufende Vertiefung 19 eingearbeitet, in welche ein Vorsprung 42 (Figuren 6 und 7) eingreift, der gemäss Figur 7 über einem Auflagenocken 16 angeordnet ist. Seitlich neben jedem Anschlagnocken 17 sind jeweils Vertiefungen 41 eingearbeitet, in welche jeweils ein Vorsprung 42 einrastbar ist. Die Einheit 10 kann somit in jeder der beiden Drehpositionen verrastet werden. Die Auflagenocken 16 und die Aufschlagnocken 17 können jeweils einfach als auch mehrfach vorhanden sein. Dies gilt auch für die durch die Vorsprünge 42 und Vertiefungen 41 gebildete Rastvorrichtung. Die Anschlagnocken 17 sind gemäss den Figuren 2 und 3 keilförmig ausgebildet, und gleiten an den schmalen, vorspringenden Nocken 16 seitlich ab, falls zufälligerweise beim Einsetzen der Einheit 10 in das Gehäuse 1 die Nocken 17 auf die Auflagenocken 16 auftreffen sollten. Die Einheit 10 kann somit auch in dieser Hinsicht automatisch in das Gehäuse 1 eingesetzt werden. Bei einer Handmontage ist ein Sichtkontakt zu den Nocken 17 und 16 nicht notwendig.The aforementioned two rotational positions are determined by stop cams 17 on the lower edge of the unit 10 and by support cams 16 on the inside 14 of the housing 1. A circumferential recess 19 is machined between two stop cams 17 in the outer side 18 of the unit 10, into which a projection 42 (FIGS. 6 and 7) engages, which is arranged according to FIG. 7 above a support cam 16. On the side next to each stop cam 17 there are recesses 41, into each of which a projection 42 can be latched. The unit 10 can thus be locked in either of the two rotational positions. The support cams 16 and the impact cams 17 can each be single or multiple. This also applies to the locking device formed by the projections 42 and depressions 41. The stop cams 17 are wedge-shaped according to FIGS. 2 and 3, and slide laterally on the narrow, projecting cams 16, if the cams 17 should accidentally hit the support cams 16 when the unit 10 is inserted into the housing 1. The unit 10 can thus also be automatically inserted into the housing 1 in this regard. In the case of manual assembly, visual contact with the cams 17 and 16 is not necessary.
