Abstract

The equipment has an operating device (11), in which a valve body (2) is lifted from a discharge unit (10), by a pulling element (3), in order to cause a full or partial flushing process. In the case of a partial flush, the body is loaded with an additional weight (4). During a partial flush, the element engages on the weight, and the weight engages on the body. After a partial flush, the device can be uncoupled by an member (1) on the discharge unit. This may be a lever with two arms, and one arm (6) may lift the valve body by engaging on the weight. The other arm may be forced to make a switching movement to release the weight before the body reaches its upper end position.

Description

Die Erfindung betrifft eine Spüleinrichtung in einem WC-Spülkasten nach dem Oberbegriff des Anspruchs 1.The invention relates to a flushing device in a toilet cistern according to the preamble of claim 1.

Eine Spüleinrichtung dieser Art ist im Stand der Technik durch die EP-A-0 448 092 bekannt geworden. Bei dieser ist zur Auslösung der Teilspülung ein Hebelsystem mit zwei separat gelagerten Hebeln vorgesehen, zwischen denen eine Kupplungsvorrichtung mit einem Haken angeordnet ist, der in einem Winkel drehbar an einem freien Endbereich eines ersten Hebels angeordnet ist, wobei Führungsmittel durch ein geneigtes Teil gebildet sind, das aus genanntem zweiten Hebel an der Stelle des genannten, am genannten ersten Hebel befestigten Haken hervorsteht, um einen Eingriff des genannten Hakens mit dem zweiten Hebel zu ermöglichen. Mit dieser sehr aufwendigen Betätigungseinrichtung ist an sich gewährleistet, dass nach der Auslösung einer Teilspülung die Schliessbewegung des Ventilkörpers durch die Bedienungsperson nicht beeinflussbar ist. Die Schliessbewegung wird insbesondere auch dann präzise ausgeführt, wenn die Bedienungsperson die entsprechende Taste der Betätigungsvorrichtung ständig niederdrückt. Bei dieser Spüleinrichtung wird als nachteilig angesehen, dass sie an ein vergleichsweise aufwendiges Hebelsystem gebunden ist und beispielsweise eine Betätigungsvorrichtung mit einem Druckknopf nicht möglich ist. Das Hebelsystem befindet sich wenigstens teilweise über dem Spülwasser und ist sehr anfällig auf Kalkablagerungen, die zu Störungen führen können.A flushing device of this type is state of the art made known by EP-A-0 448 092. With this one a lever system with two separately for triggering the partial flush stored levers provided between which one Coupling device is arranged with a hook, which in an angle rotatable at a free end portion of a first Lever is arranged, with guide means through a inclined part are formed, the so-called second lever in the place of said first lever attached hook protrudes to engage the said To enable hooks with the second lever. With this very complex actuator is in itself ensures that after triggering a partial rinse the closing movement of the valve body by the operator cannot be influenced. The closing movement is carried out precisely even when the Operator the corresponding button of the actuator constantly depresses. With this flushing device is considered a disadvantage that it is comparatively complex lever system is bound and for example an actuator with a push button not possible. The lever system is at least partly over the rinse water and is very susceptible on limescale deposits that can lead to faults.

Eine Spüleinrichtung mit einer Betätigungsvorrichtung, die wahlweise eine Voll- oder Teilspülung ermöglicht, ist zudem durch die DE-A-36 18 671 des Anmelders bekannt geworden. Bei dieser wird im Fall einer Teilspülung mittels einer am oberen Ende des Ventilkörpers angeordneten Umsteuervorrichtung das Zusatzgewicht an den Ventilkörper angehängt. Eine Kupplung der Betätigungsvorrichtung nach Auslösung einer Teilspülung ist hier nicht vorgesehen.A flushing device with an actuator that either full or partial rinsing is also possible made known by the applicant's DE-A-36 18 671. In the case of partial rinsing, this is done using an upper end of the valve body arranged reversing device the additional weight is attached to the valve body. A Coupling of the actuator after triggering one Partial rinsing is not provided here.

Schliesslich zeigt die DE-U-92 15 972 eine Spüleinrichtung, bei der zur Teilentleerung des Spülkastens einer Betätigungsvorrichtung ein Schwimmkörper zugeordnet ist, welcher mit einem Zusatz-Hilfsventil verbunden ist. Diese Einrichtung ist im Aufbau sehr aufwendig und bestehen aus vielen Einzelteilen.Finally, DE-U-92 15 972 shows a flushing device, for the partial emptying of the cistern of an actuator a floating body is assigned, which is connected to an auxiliary auxiliary valve. This facility is very complex to build and consist of many Individual parts.

Der Erfindung liegt die Aufgabe zugrunde, eine Spüleinrichtung der genannten Art zu schaffen, die universeller einsetzbar und insbesondere eine Druckknopfbetätigung ermöglicht und die sich zudem durch einen einfacheren Aufbau auszeichnet. Die Lösung der Aufgabe ergibt sich durch die im unabhängigen Patentanspruch aufgeführten Merkmale.The invention has for its object a flushing device of the type mentioned to create the more universally applicable and in particular enables a push button operation and which is also due to a simpler structure distinguished. The solution to the problem results from the Features listed in the independent claim.

Bei der erfindungsgemässen Spüleinrichtung kann die Betätigungsvorrichtung beliebig ausgebildet sein und benötigt lediglich einen Hebel, mit dem das Zusatzgewicht angehoben werden kann. Ein solches Zusatzgewicht ist auch bei einer Druckknopfbetätigung möglich. Das Schwimmerventil der Ablaufgarnitur kann ebenfalls in üblicher Weise ausgebildet sein und benötigt kein Hilfsventil und dergleichen. Dadurch ergibt sich die angestrebte universelle Einsatzmöglichkeit der erfindungsgemässen Spüleinrichtung.In the flushing device according to the invention, the actuating device can be of any design and only required a lever with which the additional weight is raised can be. Such an additional weight is also one Push button operation possible. The float valve of the waste set can also be formed in the usual way and does not require an auxiliary valve and the like. Thereby the desired universal application results the flushing device according to the invention.

Ein wesentlicher Vorteil der Erfindung wird auch darin gesehen, dass der Ventilkörper durch keine Schalt- oder Verbindungsmittel belastet werden muss und dadurch der Schwimmerauftrieb minimal gehalten werden kann. Somit ist eine Ausführung möglich, bei der bei einer Vollspülung das unbelastete Ventilrohr angehoben wird.An essential advantage of the invention is also seen in that the valve body by no switching or connecting means must be loaded and thus the float buoyancy can be kept to a minimum. So is one Execution possible in which the unloaded during a full flush Valve pipe is raised.

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 nachfolgend anhand der Zeichnung näher erläutert. Es zeigen:

Fig. 2
a longitudinal section according to Figure 1, but after triggering a partial rinse.

Die in der Zeichnung gezeigte Spüleinrichtung 50 ist in einem üblichen und hier lediglich abschnittsweise gezeigten Spülkasten 12 eingesetzt. Sie besteht im wesentlichen aus einer Ablaufgarnitur 10 und einer Betätigungseinrichtung 11, mit der zur Auslösung einer Spülung ein Ventilkörper 2, der gleichzeitig ein Ueberlaufrohr sein kann, von einem Ventilsitz 19 abgehoben wird, worauf im Spülkasten 12 befindliches Wasser durch seitliche Fenster 17 in ein Schwimmergehäuse 15 und von dort durch eine Oeffnung 49 in eine hier nicht gezeigte WC-Schüssel gelangt. The flushing device 50 shown in the drawing is in one usual and shown here only in sections Cistern 12 used. It essentially consists of a drain fitting 10 and an actuator 11, with which a valve body 2 for triggering a flush, which can also be an overflow pipe from one Valve seat 19 is lifted, which is located in the cistern 12 Water through side windows 17 into a float housing 15 and from there through an opening 49 into a toilet bowl, not shown here.

Durch die Auftriebskraft eines im Schwimmergehäuse 15 angeordneten Schwimmers 16 wird der Ventilkörper 2 in Schwebe gehalten, bis der Spülkasten teilweise oder ganz entleert ist.By the buoyancy of one arranged in the float housing 15 The float 16 causes the valve body 2 to float held until the cistern is partially or completely emptied is.

Ablaufgarnituren 10 mit einem Schwimmer 16 und einem abhebbaren Ventilkörper 2 sind seit langem bekannt. Zu ihrer Befestigung ist ein Stutzen 18 des Schwimmergehäuses 15 durch eine Oeffnung 13 im Boden des Spülkastens 12 eingesetzt und mit einer von der Unterseite aufgeschraubten Befestigungsmutter 14 fixiert.Drain fittings 10 with a float 16 and a removable Valve body 2 have been known for a long time. To fix them is a nozzle 18 of the float housing 15 through an opening 13 inserted in the bottom of the cistern 12 and with a fastening nut screwed on from the bottom 14 fixed.

Die Betätigungsvorrichtung 11 ist so ausgebildet, dass wahlweise eine Voll- oder Teilspülung möglich ist. Zur Ausübung einer Vollspülung besitzt die Betätigungsvorrichtung 11 einen Hebel 25, der schwenkbar an einem Steg 24 gelagert ist und der eine von der Aussenseite des Spülkastens zugängliche Taste 26 aufweist. Mit einem Ende 51 greift der Hebel 25 in einen Schlitz 22 einer am Ventilkörper 2 angeformten Lasche 21 ein. Der Hebel 25 kann auch ein Druckknopf sein, wie er insbesondere bei Spülkästen aus Keramik verwendet wird. Wesentlich ist lediglich, dass durch eine Betätigung der Ventilkörper 2 angehoben werden kann. Beim Niederdrücken der Taste 26 wird der Ventilkörper 2 mit dem Ventilteller 20 angehoben, so dass das Ablaufventil öffnet. Der Schwimmer 16 hält den angehobenen Ventilkörper 2 in Schwebe, bis der Spülkasten 12 im wesentlichen vollständig entleert ist. Anschliessend fällt der Ventilkörper 2 wieder nach unten und schliesst das Ventil, wonach der Spülkasten über ein hier nicht gezeigtes Einlaufventil wieder bis zu einem vorbestimmten Niveau gefüllt wird.The actuating device 11 is designed such that either full or partial rinsing is possible. To exercise the actuator has a full flush 11 a lever 25 which is pivotally mounted on a web 24 and is the one accessible from the outside of the cistern Button 26 has. With an end 51 it engages Lever 25 in a slot 22 formed on the valve body 2 Tab 21 a. The lever 25 can also be a push button be, as he is especially with ceramic cisterns is used. It is only essential that through a Actuation of the valve body 2 can be raised. At the Depressing the button 26, the valve body 2 with the Valve plate 20 raised so that the drain valve opens. The float 16 holds the raised valve body 2 in Hover until the cistern 12 is essentially complete is emptied. The valve body 2 then falls again down and closes the valve, after which the cistern via an inlet valve not shown here again up to is filled to a predetermined level.

Zur Auslösung einer Teilspülung ist die Betätigungsvorrichtung 11 mit einem zweiten Hebel 30 versehen, der ebenfalls am Steg 24 verschwenkbar ist und eine von aussen bedienbare Taste 31 aufweist. Die Taste 31 ist auch hier lediglich eine Handhabe, die beispielsweise auch ein Druckknopf sein kann. Ein unteres Ende 52 des Hebels 30 greift in eine Oeffnung 28 einer Lasche 27 ein, die am oberen Ende eines Zugelementes 3, insbesondere einer Zugstange angebracht ist. Die Zugstange 3 ist in einer Bohrung 41 eines an einem Gewichtskörper 4 angeformten Ansatz 40 verschieblich geführt und erstreckt sich nach unten bis zu einem Deckel 38 des Schwimmergehäuses 15. Am unteren Ende der Zugstange 3 ist ein Lagerteil 34 angebracht, an dem ein Kupplungsorgan 1 schwenkbar gelagert ist. Das Kupplungsorgan 1 ist ein zweiarmiger Hebel, wobei ein nach unten gerichteter Arm 5 durch eine Oeffnung 36 in den Deckel 38 in das Schwimmergehäuse 15 eingreift. Der andere Arm 6 ist schräg nach oben gerichtet und gegen die Aussenseite des Ventilkörpers 2 geneigt. Am Kupplungsorgan 1 ist eine Nase 39 angeformt, die in der Stellung gemäss Figur 1 an der Oberseite des Deckels 38 anliegt. Eine weitere am Kupplungsorgan 1 angeformte Nase 53 liegt in der in Figur 1 gezeigten Stellung auf einem Nocken 35 des Deckels 38 auf und hält den Arm 6 in der gezeigten Position. The actuating device is used to trigger a partial flush 11 provided with a second lever 30, which is also is pivotable on the web 24 and one that can be operated from the outside Button 31 has. The key 31 is also only one here Handle, which can also be a push button, for example can. A lower end 52 of the lever 30 engages in one Opening 28 of a tab 27 at the top of a Pull element 3, in particular a pull rod attached is. The pull rod 3 is one in a bore 41 Weight body 4 molded approach 40 slidably guided and extends down to a cover 38 of the float housing 15. At the lower end of the tie rod 3 a bearing part 34 is attached to which a coupling member 1 is pivotally mounted. The coupling member 1 is a two-armed lever, one downward arm 5 through an opening 36 in the cover 38 in the float housing 15 engages. The other arm 6 is obliquely upwards directed and inclined towards the outside of the valve body 2. A nose 39 is formed on the coupling member 1 in the position shown in Figure 1 on the top of the lid 38 is present. Another nose formed on the coupling member 1 53 lies in the position shown in FIG Cam 35 of the lid 38 and holds the arm 6 in the shown Position.

Wird die Zugstange 3 durch Verschwenken des Hebels 30 nach oben bewegt, so wird gleichzeitig das Kupplungsorgan 1 mit nach oben gezogen. Hierbei untergreift der eingeschwenkte Arm 6 den Gewichtskörper 4 an einer Schulter 55 und zieht diesen ebenfalls mit nach oben. Da gleichzeitig eine Anschlagfläche 7 am oberen Ende des Gewichtskörpers 4 an einer Schulter 23 des Ventilkörpers 2 anliegt, wird dieser ebenfalls nach oben bewegt. Die Endstellung dieser nach oben gerichteten Bewegung ist in Figur 2 gezeigt. Diese Stellung ist nach vollständigem Niederdrücken der Taste 31 erreicht. Das Ablaufventil ist in dieser Stellung offen und das Spülwasser kann in Richtung des Pfeiles 48 nach aussen in die hier nicht gezeigte WC-Schüssel fliessen. Kurz vor erreichen dieser Endstellung kommt eine am unteren Ende des Arms 5 angeordnete Steuerfläche 37 in Eingriff mit einem Rand 56 der Oeffnung 36, wodurch der Arm 5 im Gegenuhrzeigersinn um das Lagerelement 34 und der Arm 6 ebenfalls im Gegenuhrzeigersinn verschwenkt werden. Der Eingriff des Arms 6 an der Schulter 55 ist somit in der in Figur 2 gezeigten Endstellung aufgehoben. Die Zugstange 3 ist deshalb in dieser Stellung nicht mehr mit dem Gewichtskörpers 4 gekuppelt, so dass sich dieser unabhängig von der Stellung der Zugstange 3 nach unten bewegen kann.The pull rod 3 by pivoting the lever 30 after Moved up, the coupling member 1 is simultaneously with pulled up. Here, the swiveled in Arm 6 the weight body 4 on a shoulder 55 and pulls this also with up. Because at the same time a stop surface 7 at the upper end of the weight body 4 on one Shoulder 23 of the valve body 2 rests, this is also moved up. The final position after this Movement directed upwards is shown in FIG. This The position is after the button 31 is fully depressed reached. The drain valve is open and in this position the rinse water can move outwards in the direction of arrow 48 flow into the toilet bowl, not shown here. Shortly before reaching this end position comes one at the bottom of the Arms 5 arranged control surface 37 in engagement with a Edge 56 of the opening 36, whereby the arm 5 in the counterclockwise direction around the bearing element 34 and the arm 6 also in the Can be pivoted counterclockwise. The intervention of the Arms 6 on shoulder 55 is thus shown in FIG End position canceled. The tie rod 3 is therefore no longer coupled to the weight body 4 in this position, so this is regardless of position the pull rod 3 can move down.

Gleichzeitig mit der genannten Entkupplung wird ein einarmiger Hebel 8, der an seinem oberen Ende schwenkbar an einer Achse 62 des Gewichtskörpers 4 gelagert ist, verschwenkt, bis ein Zahn 61 am unteren Ende dieses Hebels 8 in einem kurzen Abstand über eine Schulter 29 des Ventilkörpers 2 angeordnet ist. Die Verschwenkung erfolgt durch Kulissen 45, die in einer Oeffnung 44 des Deckels 38 geführt sind. Wie die Figur 2 zeigt, befindet sich bei vollständig geöffnetem Ventil eine untere Anschlagfläche 57 des Zahns 61 nur wenig über der Schulter 29. Bewegt sich der von der Zugstange 3 entkuppelte Gewichtskörper 4 am Ventilkörper 2 entlang nach unten, so liegt nach kurzem Weg der Zahn 61 auf der Schulter 29 auf, wodurch die genannte Bewegung unterbrochen und der Ventilkörper 2 durch das Gewicht des Gewichtskörpers 4 belastet wird. Das Gesamtgewicht des Ventilkörpers 2 und des Gewichtskörpers 4 ist so bemessen, dass die Auftriebskraft des Schwimmers 16 nicht ausreicht, um eine vorzeitige Schliessbewegung des Ventilkörpers 2 zu verhindern. Der Ventilkörper 2 bewegt sich deshalb nach dem Einklinken des Gewichtskörpers 4 vergleichsweise schnell nach unten, bis der Ventilteller 20 auf dem Ventilsitz 19 aufliegt. Infolge der vorzeitigen Schliessung des Ventils verbleibt eine vorbestimmte Teilmenge des Spülwassers im Spülkasten 12.Simultaneously with the decoupling mentioned, one arm is used Lever 8, which is pivotable at its upper end on a Axis 62 of the weight body 4 is pivoted, until a tooth 61 at the lower end of this lever 8 at a short distance over a shoulder 29 of the valve body 2 is arranged. The pivoting takes place through Scenes 45, which are guided in an opening 44 of the cover 38 are. As shown in Figure 2, is at complete open valve a lower stop surface 57 of the Zahns 61 just a little over shoulder 29 from the tie rod 3 decoupled weight body 4 on the valve body 2 down, so after a short distance the Tooth 61 on shoulder 29, causing said movement interrupted and the valve body 2 by the weight the weight body 4 is loaded. The total weight of the Valve body 2 and the weight body 4 is dimensioned so that the buoyancy of the float 16 is not sufficient around a premature closing movement of the valve body 2 prevent. The valve body 2 therefore moves after Locking the weight body 4 relatively quickly down until the valve plate 20 on the valve seat 19 lies on. As a result of the premature closing of the valve a predetermined portion of the rinse water remains in the Cistern 12.

Während der Schliessbewegung des Ventilkörpers 2 gleitet der Zahn 61 auf einer an einem Einsatz 42 der Ablaufgarnitur 10 angeordneten Steuerfläche 58 nach unten. Diese Steuerfläche 58 ist so ausgebildet, dass das Einklinkorgan 8 kurz vor der Schliessung des Ablaufventils nach aussen ausgelenkt und dadurch der Eingriff des Zahn 61 an der Schulter 29 aufgehoben wird. Etwa gleichzeitig wird das Kupplungsorgan 1 durch einen Eingriff des Nockens 35 an der Nase 53 in die in Figur 1 gezeigte Ausgangsstellung zurückverschwenkt. Das Zugelement 3 senkt sich während der genannten Schliessbewegung selbsttätig infolge seines Eigengewichtes. Wesentlich ist nun, dass die Schliessbewegung auch dann erfolgt, wenn die Taste 31 während der Schliessbewegung in der in Figur 2 gezeigten unteren Stellung gehalten wird. Dies ist möglich infolge der oben erläuterten Entkupplung. Das Kupplungsorgan 1 bleibt in diesem Fall in der in Figur 2 gezeigten Position, während der Gewichtskörper 4 sich nach unten bewegt und das Kupplungsorgan 1 in einer Ausnehmung 59 aufnimmt. Wird die Taste 31 schliesslich losgelassen, so senkt sich die Zugstange 3 mit dem Kupplungsorgan 1 nach unten in die in Figur 1 gezeigte Ausgangsstellung. Nach dem Schliessen des Auslaufventils wird der Spülkasten 12 in an sich bekannter Weise durch ein hier nicht gezeigtes Einlaufventil wieder gefüllt. Die Spüleinrichtung 50 ist hierauf wieder für eine wahlweise Voll- oder Teilspülung bereit.Slides during the closing movement of the valve body 2 tooth 61 on an insert 42 of the drain fitting 10 arranged control surface 58 down. This control surface 58 is designed such that the latching element 8 deflected outwards shortly before the drain valve closed and thereby the engagement of tooth 61 on the shoulder 29 is canceled. At about the same time, the coupling member 1 by an engagement of the cam 35 on the nose 53 pivoted back into the starting position shown in Figure 1. The tension element 3 lowers during the said Closing movement automatically due to its own weight. It is now essential that the closing movement also occurs if the button 31 during the closing movement held in the lower position shown in Figure 2 becomes. This is possible due to the above Uncoupling. The coupling member 1 remains in this case the position shown in Figure 2, during the weight body 4 moves down and the coupling member 1 in a recess 59 receives. Finally, the key 31 released, the pull rod 3 lowers with the Coupling member 1 down into the starting position shown in Figure 1. After closing the outlet valve the cistern 12 in a manner known per se by a here Inlet valve, not shown, refilled. The flushing device 50 is then again for an optional full or partial rinse ready.

Verglichen mit einer üblichen Spüleinrichtung ohne Teilspülung ist die Spüleinrichtung gemäss der vorliegenden Erfindung vergleichsweise mit wenigen einfachen und robusten Zusatzteilen realisierbar. Diese Zusatzteile, also insbesondere die beiden Kupplungsorgane 1 und 8, sind in der Auslaufgarnitur 10 integrierbar, wodurch sich ein besonders kompakter und einfach montierbarer Aufbau ergibt. Der Ventilkörper 2 ist im Schwimmergehäuse 15 frei drehbar und durch zusätzliche Kupplungsteile nicht belastet. Wie bereits erwähnt, kann die Betätigungsvorrichtung 11 sehr unterschiedlich ausgeführt sein, weshalb die erfindungsgemässe Spüleinrichtung im wesentlichen bei allen üblichen Spülkästen und insbesondere auch bei Keramik- und Unterputzspülkästen verwendbar ist.Compared to a conventional rinsing device without partial rinsing is the flushing device according to the present invention comparatively with a few simple and robust additional parts realizable. These additional parts, in particular the two coupling elements 1 and 8 are in the outlet set 10 integrable, which makes a special compact and easy to assemble. The valve body 2 is freely rotatable in the float housing 15 not burdened by additional coupling parts. As before mentioned, the actuator 11 can be very different be executed, which is why the inventive Rinsing device essentially in all usual Cisterns and especially also for ceramic and concealed cisterns is usable.

Trotz der erheblichen Vorteile der erfindungsgemässen Spüleinrichtung ist diese ersichtlich mit verhältnismässig wenigen, einfachen und robusten Bauteilen realisierbar, so dass erfindungsgemäss eine Spüleinrichtung geschaffen wurde, welche nicht nur den sanitärtechnischen Anforderungen in hervorragender Weise Rechnung trägt, sondern aufgrund ihrer einfachen und robusten Ausführbarkeit kostenmässig günstig und betrieblich äusserst zuverlässig ist.Despite the considerable advantages of the flushing device according to the invention can this be seen with relatively few, simple and robust components realizable, so that a flushing device was created according to the invention, which not only meet the sanitary requirements takes into account in an excellent way, but because their simple and robust feasibility cost-effective is inexpensive and extremely reliable in operation.
