Description

Die Erfindung bezieht sich auf eine Ablaufarmatur eines Spülkastens gemäß der im Oberbegriff des Patentanspruchs 1 angegebenen Merkmale.The invention relates to a drain fitting of a cistern according to the features specified in the preamble of claim 1.

Aus der FR 2 678 300 A ist eine derartige Ablaufarmatur mit einem in vertikaler Richtung anhebbaren Überlaufrohr bekannt, an dessen unterem Ende ein Dichtelement eines Ablaufventils angeordnet ist. Die Ablaufarmatur enthält ein Armaturengehäuse und einen Schwimmerbehälter mit einem Schwimmer sowie wenigstens eine Zugstange zum wahlweisen Auslösen einer Großmengenspülung oder Kleinmengenspülung durch Anheben des Überlaufrohres. Der Schwimmerbehälter enthält eine erste Öffnung, durch welche beim Auslösen einer Spülung Wasser ausströmen kann, und ferner eine zweite Öffnung, welche mittels eines Verschlußelements verschließbar ist, jedoch beim Auslösen der Kleinmengenspülung geöffnet ist.From FR 2 678 300 A such a drain fitting with an in vertical direction liftable overflow pipe known, on the lower A sealing element of a drain valve is arranged at the end. The drain fitting contains a valve body and a float tank a float and at least one pull rod to choose from Triggering a large quantity flush or small quantity flush Lifting the overflow pipe. The float tank contains a first one Opening through which water flows out when a flush is triggered can, and further a second opening, which by means of a closure element is lockable, however, when the small quantity flush is triggered is open.

Des Weiteren ist aus der EP 723 050 A eine Ablaufarmatur bekannt, welche für eine Kleinmengenspülung und Großmengenspülung ausgelegt ist und ein Ablauf- oder Bodenventil mit einem Ventil- oder Überlaufrohr enthält. In zwei separaten übereinander angeordneten Schwimmerbehältern ist jeweils ein Schwimmer angeordnet. Der untere Schwimmer bleibt bei Auslösung der Kleinmengenspülung mittels eines Riegels arretiert und das Überlaufrohr wird nur vom oberen Schwimmer abgestützt, welcher auf dem im Spülkasten enthaltenen Wasser aufschwimmt. Zur Auslösung der Großmengenspülung wird auch der untere Schwimmer freigegeben, so daß das Überlaufrohr, an dessen unterem Ende das Ventil bzw. dessen Ablaufdichtung angeordnet ist, von beiden Schwimmern abgestützt wird.Furthermore, a drain fitting is known from EP 723 050 A, which is designed for small-quantity flushing and large-quantity flushing and a drain or bottom valve with a valve or overflow pipe contains. In two separate float tanks arranged one above the other a float is arranged. The lower swimmer remains locked when a small quantity flush is triggered by a bolt and the overflow pipe is only supported by the upper float, which is on the water contained in the cistern floats. To trigger the Large-volume flushing also releases the lower float, so that the overflow pipe, at the lower end of which the valve or its drain seal is arranged, is supported by both swimmers.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, die Ablaufarmatur der genannten Art dahingehend weiterzubilden, daß der konstruktive Aufwand reduziert wird und gleichwohl eine funktionssichere Groß- oder Kleinmengenspülung durchführbar ist. Der Fertigungsaufwand und die Anzahl der Bauteile sollen reduziert werden. Der Einbau der Ablaufarmatur in einen Spülkasten und nötigenfalls erforderliche Reinigungs- oder Servicearbeiten sollen in einfacher Weise durchgeführt werden können.Proceeding from this, the object of the invention is the drain fitting of the type mentioned to the extent that the constructive Effort is reduced and nevertheless a functionally safe large or small quantity flushing can be carried out. The manufacturing effort and the number of components should be reduced. The installation the drain fitting in a cistern and, if necessary, necessary cleaning or Service work should be carried out in a simple manner.

Die Lösung dieser Aufgabe erfolgt gemäß den Merkmalen des Patentanspruchs 1.This object is achieved in accordance with the features of patent claim 1.

Die erfindungsgemäße Ablaufarmatur zeichnet sich durch einen einfachen Aufbau mit wenigen Bauteilen aus. Es ist nur ein einziger Schwimmerbehälter mit einem Schwimmer im oberen Bereich des Spülkastens bzw. des Armaturengehäuses vorgesehen. Beim Auslösen der Großmengenspülung wird das Überlaufrohr mittels des einzigen Schwimmers abgestützt, und zwar so lange, bis das Wasse aus einer ersten unverschließbaren Öffnung des oben angeordneten Schwimmbehälters abgelaufen ist. Die Zugstange für die Auslösung der Großmengenspülung ist mit dem Überlaufrohr gekoppelt und enthält ferner in zweckmäßiger Weise einen Abstandshalter, über welchen die Abstützung des Überlaufrohres auf dem einzigen Schwimmer erfolgt. Über die Größe der ersten Öffnung wird unter Berücksichtigung des Abstandes zum Spülkastenboden die Auslaufmenge der Großmengenspülung gesteuert. Das Schwimmergehäuse enthält eine zweite Öffnung, welche während der Großmengenspülung geschlossen ist und bei Auslösung der Kleinmengenspülung geöffnet wird. Während der Kleinmengenspülung läuft folglich das Wasser schneller aus dem Schwimmerbehälter, so daß der Schwimmer schneller absinkt und das Bodenventil des Spülkastens folglich früher verschlossen wird als bei der Großmengenspülung, so daß letztendlich weniger Wasser ausgespült wird. Die genannten Öffnungen sind zweckmäßig als separate Öffnungen ausgebildet, doch können im Rahmen der Erfindung die beiden Öffnungen auch zu einer einzigen gemeinsamen Öffnung mit zwei Teilbereichen kombiniert werden. Der erste Teilbereich entspricht der erläuterten ersten Öffnung für die Großmengenspülung, während der zweite Teilbereich der zweiten Öffnung für die Kleinmengenspülung zusammen mit dem zugeordneten Verschlußelement dient. In bevorzugter Weise ist der Ausströmquerschnitt der ersten Öffnung bzw. des ersten Teilbereiches kleiner als der Ausströmquerschnitt der zweiten Öffnung bzw. des zweiten Teilbereiches. Insbesondere ist der Ausströmquerschnitt der zweiten Öffnung bzw. des zweiten Öffnungs-Teilbereiches um einen vorgegebenen Faktor größer als der Ausströmquerschnitt der ersten Öffnung bzw. des ersten Öffnungs-Teilbereiches, insbesondere um einen Faktor größer 2, bevorzugt größer 4. Da nur ein Schwimmer und ein Schwimmerbehälter vorgesehen sind, ist der Fertigungsaufwand im Vergleich mit vorbekannten Zweimengenarmaturen nicht unerheblich reduziert. The drain fitting according to the invention is characterized by a simple structure few components. It is just a single float tank with a float provided in the upper area of the cistern or the valve body. At the The overflow pipe is triggered by the single float supported, and so long, until the water from a first unlockable Opening of the floating tank above has expired. The pull rod for the triggering of the large volume flushing is coupled to the overflow pipe and contains further expediently a spacer, via which the support of the Overflow pipe is done on the single float. About the size of the first opening taking into account the distance to the cistern floor, the outlet quantity of the Large volume flushing controlled. The float housing contains a second opening which is closed during the large quantity flushing and when the Small-volume flushing is opened. This therefore runs during the small quantity flushing Water from the float tank faster, so that the float sinks faster and the bottom valve of the cistern is consequently closed earlier than in the Large-volume flushing, so that ultimately less water is flushed out. The above Openings are expediently designed as separate openings, but can in Within the scope of the invention, the two openings also form a single joint Opening can be combined with two sections. The first section corresponds to the explained first opening for large-volume flushing, while the second section the second opening for the small quantity flushing together with the assigned Closure element serves. The outflow cross section is preferably the first Opening or of the first partial area smaller than the outflow cross section of the second Opening or the second section. In particular, the outflow cross section is second opening or the second opening partial area by a predetermined Factor larger than the outflow cross-section of the first opening or of the first partial opening area, in particular by a factor greater than 2, preferably greater than 4. Since only one Float and a float tank are provided, the manufacturing costs in Not inconsiderably reduced compared to previously known two-volume fittings.

Das Armaturengehäuse 6 enthält ein Unterteil 14 und an dieses nach oben anschließend ein Oberteil 16, weiche im wesentlichen rohrfömig ausgebildet sind und in welchen das Überlaufrohr 4 in Richtung der Längsachse 8 bewegbar angeordnet und/oder geführt ist. Zweckmäßig ist zwischen dem Überlaufrohr 4 und der Innenfläche des rohrförmigen Armaturengehäuses 6 bzw. dessen Unterteil 14 und Oberteil 16 ein Ringspalt vorhanden. Wesentlich ist, daß im Bereich des Unterteils 14 kein Schwimmerbehälter und Schwimmer angeordnet sind, sondern daß ein einziger Schwimmerberhälter 18 im oberen Bereich des Armaturengehäuses 6 vorgesehen ist bzw. im Oberteil 16 zugeordnet ist. Der Schwimmerbehälter 18 ist zweckmäßig an das Oberteil 16 angeformt und/oder einteilig mit dem Oberteil und/oder insgesamt mit dem Armaturengehäuse 6 ausgebildet.The valve housing 6 contains a flange 12 at the lower end, which in particular is hood-shaped and in which the sealing element when a flush is triggered 2 can be moved into it. The valve housing 6 contains a lower part 14 and this upwards then an upper part 16, which is essentially tubular are formed and in which the overflow pipe 4 in the direction of the longitudinal axis 8 is movably arranged and / or guided. It is useful between the overflow pipe 4 and the inner surface of the tubular fitting housing 6 or its lower part 14 and upper part 16 an annular gap is present. It is essential that in the area of the lower part 14 no float tank and float are arranged, but that a single one Float tank 18 is provided in the upper region of the valve housing 6 or assigned in the upper part 16. The float tank 18 is useful for that Shaped upper part 16 and / or in one piece with the upper part and / or in total with the Fitting housing 6 is formed.

Im Schwimmerbehälter 18 ist ein Schwimmer 20 vorgesehen, welcher beim Auslösen eines Spülvorganges in bekannter Weise auf dem Wasser des Spülkastens nach oben aufschwimmt. Das Schwimmergehäuse und ebenso der darin bewegbar angeordnete Schwimmer 20 sind im oberen Teil des Spülkastens bzw. im oberen Bereich des Überlaufrohres 4 angeordnet. Mittels eines Abstandshalters 22, der auf der Oberkante des Schwimmers 20 aufliegt, wird dieser in der Ruhestellung unten gehalten. Der Abstandshalter 22 ist mit dem Überlaufrohr 4 gekoppelt.In the float tank 18, a float 20 is provided, which when triggered a flushing process in a known manner on the water of the cistern upwards floats. The float housing and also the one arranged movably therein Floats 20 are in the upper part of the cistern or in the upper area of the overflow pipe 4 arranged. By means of a spacer 22 which on the upper edge of the Floats 20 rests, this is held down in the rest position. The spacer 22 is coupled to the overflow pipe 4.

Hierzu wurde beim Drücken einer hier nicht weiter dargestellten Auslösetaste eine erste Zugstange 24 nach oben gezogen. Die erste Zugstange 24 für die Großmengenspülung ist mit dem Überlaufrohr 4 gekoppelt, welches somit gleichfalls in die dargestellte Position angehoben ist, so daß das Dichtelement 2 das Bodenventil öffnet und das Spülwasser ausströmen kann. Mit der ersten Zugstange 24 ist ferner der Abstandshalter 22 verbunden, und zwar zweckmäßig einteilig, dessen unteres Ende auf der Oberfläche des einzigen Schwimmers 20 aufliegt. Der Schwimmerbehälter 18 enthält zweckmäßig in seinem Boden 26 eine Öffnung 28, durch welche das im Schwimmerbehälter 18 befindliche Wasser abströmen kann, während gleichzeitig durch das Ablaufventil das Spülwasser ausströmt. Die Ausspülmenge ist durch die entsprechend dimensionierte Öffnung 28 derart gesteuert, das das Leerlaufen des Schwimmergehäuses etwas länger andauert als das Ablaufen des Spülwassers durch das Ablaufventil. Sobald der Schwimmerbehälter 18 nahezu leergelaufen ist, hat das Dichtelement 2 den Ventilsitz erreicht und das Bodenventil bzw. die Ablaufarmatur ist wieder geschlossen.Fig. 2 shows the two-quantity drain fitting according to the invention after triggering a Large flush. To do this, when pressing one, was not shown here Trigger button a first pull rod 24 pulled up. The first tie rod 24 for the large quantity flushing is coupled to the overflow pipe 4, which is therefore also is raised in the position shown, so that the sealing element 2, the bottom valve opens and the rinsing water can flow out. With the first tie rod 24 is also Spacer 22 connected, and expediently in one piece, the lower end of the surface of the single float 20 rests. The float tank 18 contains Appropriately in its bottom 26, an opening 28 through which that in the float tank 18 water can flow out while at the same time through the drain valve the rinse water flows out. The flushing volume is dimensioned accordingly Opening 28 controlled so that the floating of the float housing somewhat takes longer than the flushing water drains through the drain valve. Once the Float tank 18 is almost empty, the sealing element 2 has the valve seat reached and the bottom valve or drain fitting is closed again.

When lifting the second Pull rod 30, the cam 34 rests on top of the driver 32 and as a result the spacer 22 and the overflow pipe 4 are raised upwards. The The area above the cam 34 is free or contains the pull rod 30 there Small volume flushing a slot 36 in which the cam 34 when lifting the first pull rod 24 for large-volume flushing can be moved upward without to raise the second tie rod 30.

Mit der zweiten Zugstange 30 ist erfindungsgemäß ein Verschlußelement 38 einer zweiten Öffnung 40 des Schwimmerbehälters 18 gekoppelt. Das Verschlußelement 38 ist zweckmäßig als ein Schieber ausgebildet, welcher beim Anheben der zweiten Zugstange gleichfalls angehoben wird und die zweite Öffnung 40 freigibt. In zweckmäßiger Weise sind die zweite Zugstange 30, der Mitnehmer 32 und das Verschlußelement 38 einstückig als ein einziges Bauteil ausgebildet. Um ein möglichst schnelles Abströmen des Wassers für die Kleinmengenspülung zu erhalten, ist der Ausströmquerschnitt der zweiten Öffnung 40 um einen vorgegebenen Faktor größer als der Ausströmquerschnitt der ersten Öffnung 28. Als zweckmäßig hat sich ein Faktor größer 2, bevorzugt größer 4, erwiesen.According to the invention, the second pull rod 30 is a closure element 38 second opening 40 of the float tank 18 coupled. The closure member 38 is Conveniently designed as a slide, which when lifting the second tie rod is also raised and the second opening 40 opens. In a convenient way the second tie rod 30, the driver 32 and the closure element 38 are in one piece formed as a single component. In order to drain the To obtain water for small-volume flushing is the outflow cross section of the second opening 40 by a predetermined factor larger than the outflow cross section the first opening 28. A factor greater than 2, preferably greater, has proven to be expedient 4, proven.

Das Verschlußelement bzw. der Schieber 38 sind bevorzugt in einer Kammer 42 angeordnet, welche vom Innenraum des Schwimmerbehälters 18 an dessen Innenseite durch eine innere Kammerwand 44 getrennt ist. Diese Kammerwand 44 enthält an ihrem unteren Ende die zweite Öffnung 40. In dieser besonderen Ausgestaltung enthält die Kammer 42 im Boden eine weitere Öffnung, durch welche, sofern die zweite Öffnung 40 freigegeben ist, das Wasser aus dem Schwimmerbehälter 18 ausströmen kann. Diese weitere Öffnung 41 ist immer vollständig geöffnet.The closure element or the slide 38 are preferably arranged in a chamber 42, which from the interior of the float tank 18 on the inside is separated by an inner chamber wall 44. This chamber wall 44 contains on her lower end, the second opening 40. In this particular embodiment, the Chamber 42 in the bottom another opening through which, if the second opening 40th is released, the water can flow out of the float tank 18. This further opening 41 is always fully open.

Desweiteren ist in der Kammer 42 eine Führungsleiste 46 für die Zugstange bzw. dem Schieber 38 vorgesehen. Die Führungsleiste 46 und ebenso die Kammerwand 44 sind im wesentlichen parallel zur Längsachse angeordnet, wodurch eine gute vertikale Führung gewährleistet ist. Die Kammerwand 44 und die Führungsleiste 46 sind ebenso wie der Schwimmerbehälter 18 einstückig und integral mit dem Armaturengehäuse 6 ausgebildet. Die radial innenliegende Kammer 42 ist unten offen ausgebildet, so daß bei geöffneter zweiter Öffnung 40 das Wasser aus dem Schwimmerbehälter 18 ungehindert nach unten abströmen kann. Es ist ersichtlich, daß bei der Kleinmengenspülung das Wasser aus dem Schwimmerbehälter 18 schneller als bei der Großmengenspülung abströmt, da das Wasser nicht nur durch die Öffnung 28, sondern zusätzlich durch die zweite Öffnung 40 ausströmen kann. Der Schwimmer 20 sinkt folglich schneller nach unten mit der Folge, daß das Dichtelement 2 auf dem Ablaufventil früher aufliegt und der Spülvorgang vorzeitig beendet wird und eine vorgebbare Restmenge im Spülkasten verbleibt.Furthermore, a guide bar 46 for the pull rod or the is in the chamber 42 Slider 38 provided. The guide bar 46 and also the chamber wall 44 are arranged substantially parallel to the longitudinal axis, creating a good vertical Leadership is guaranteed. The chamber wall 44 and the guide bar 46 are also like the float tank 18 in one piece and integrally with the valve housing 6 educated. The radially inner chamber 42 is open at the bottom, so that at opened second opening 40 the water from the float tank 18 unhindered can flow down. It can be seen that in the case of small-volume flushing, the Water from the float tank 18 faster than with large-volume flushing flows out, because the water not only through the opening 28, but also through the second opening 40 can flow out. The float 20 consequently sinks more quickly below with the result that the sealing element 2 rests earlier on the drain valve and the Flushing is ended prematurely and a predeterminable remaining amount in the cistern remains.

Fig. 4 zeigt, ähnlich Fig. 3, eine weitere Ausgestaltung, gemäß welcher der Schwimmerbehälter 18 im Boden eine Öffnung 48 aufweist, welche in zwei Teilbereiche 50, 51 unterteilt ist. Der gemäß Zeichnung rechte Teilbereich 50 ist permanent offen, während der gemäß Zeichnung linke Teilbereich 51 mittels des Verschlußelements 38 bedarfsweise abgesperrt oder geöffnet ist, wie es mit der gestrichelten Linie 52 angedeutet ist. Die zweite Zugstange 30 ist in der Position nach dem Auslösen der Kleinmengenspülung in der nach oben angehobenen Position dargestellt, in welcher der zweite Teilbereich 51 der gemeinsamen Öffnung offen ist. Zur Großmengenspülung, welche durch Anheben der ersten Zugstange 24 ausgelöst wird, strömt das Wasser ausschließlich durch den immer offenen Teilbereich 50. Hierbei wird der zweite Teilbereich 51 mittels des abgewinkelten Teils 54 des Verschlußelements 38 verschlossen gehalten. Nach dem Anheben der zweiten Zugstange 30 wird auch der zweite Teilbereich 51 freigegeben, so daß das Wasser aus dem Schwimmerbehälter 18 erheblich schneller als bei der Großmengenspülung abströmt und folglich der Spülvorgang vorzeitig beendet wird. Die Kammerwand enthält eine Aussparung 56, durch welche eine immer offene Verbindung mit dem übrigen Bereich des Inneren des Schwimmergehäuses 18 hergestellt ist. Fig. 4 shows, similar to Fig. 3, a further embodiment, according to which the float tank 18 has an opening 48 in the bottom, which in two sub-areas 50, 51 is divided. The right part 50 according to the drawing is permanently open while the left portion 51 as shown in the drawing by means of the closure element 38 if necessary is blocked or opened, as indicated by the dashed line 52. The second pull rod 30 is in the position after triggering the small quantity flush shown in the raised position, in which the second partial area 51st the common opening is open. For large-volume flushing, which is done by lifting the first pull rod 24 is triggered, the water flows exclusively through the always open section 50. Here, the second section 51 is angled by means of the Part 54 of the closure member 38 kept closed. After lifting the second tie rod 30, the second portion 51 is released, so that Water from the float tank 18 considerably faster than with large-volume flushing flows out and consequently the rinsing process is ended prematurely. The chamber wall contains a recess 56 through which an always open connection with the remaining area of the interior of the float housing 18 is made.
