Abstract

A valve controlled by the cistern water (Z2) opens and closes the drinking water feed (Z1) and is arranged in an upwardly open container provided with a throttle opening. The container is fitted in a toilet flushing cistern. A valve (V) controlled by the cistern water is formed as a counter-force-loaded piston valve (K). The counter-force (G) of the piston valve is adjustable using a positioning wheel (S). Beyond the valve a pressure flusher with separate feed conduits for cistern water and drinking water is connected.

Description

Die im sanitären Bereich eingesetzten Toilettenspülungen werden in aller Regel durch einen Anschluß an das allgemeine Trinkwassernetz versorgt.The toilet flushes used in the sanitary area are usually supplied by a connection to the general drinking water network.

Wegen zunehmender Wasserverteuerung werden jedoch vermehrt auch andere Wasserresourcen genutzt, etwa Zisternenwasser (im Folgenden als Brauchwasser bezeichnet).
Hierbei sorgen Hauswasseranlagen für den notwendigen Transport des Wassers aus dem Wasser-Sammelbecken zur Toilette.However, due to increasing water price increases, other water resources are increasingly being used, such as cistern water (hereinafter referred to as process water).
Here, domestic water systems ensure the necessary transport of water from the water collection basin to the toilet.

Ein Problem bei der Verwendung von Brauchwasser für die Toilettenspülung ist, daß keine so große Ausfallsicherheit besteht, wie bei der öffentlichen Trinkwasserversorgung; insbesondere bei einer Zisternenversorgung muß mit längeren Ausfällen im Sommer gerechnet werden.A problem with the use of process water for flushing toilets is that there is not as much reliability as with the public drinking water supply; Especially in the case of a cistern supply, longer failures in summer can be expected.

Ein einfaches Umschalten auf Trinkwasser in diesen Zeiten ist, bei den heutigen Toilettenspülungen mit nur einer Zuleitung, problematisch und im Allgemeinen von Seiten der Wasserwerke untersagt, da es durch Restwasser zur Verschmutzung des Trinkwassers kommen kann.A simple switch to drinking water in these times is problematic with today's toilet flushing with only one supply line and is generally prohibited on the part of the waterworks because residual water can contaminate the drinking water.

In der deutschen Offenlegungsschrift 28 08 656 wurde deshalb ein Spülkasten mit zwei getrennten Zuläufen beschrieben. Jedoch fehlt dieser Einrichtung das echte Umschalten von Brauch- auf Trinkwasser; lediglich eine größere Durchlaufbohrung beim Brauchwasserzulauf bewirkt ein bevorzugtes Auffüllen des Toilettenspülkastens mit Brauchwasser. Die Nachteile liegen darin, daß bei voll funktionierender Brauchwasserzufuhr immer Trikwasser zugeführt wird und bei ausgefallener Brauchwasserzufuhr das Auffüllen des Toilettenspülkastens mit Trinkwasser deutlich, gegenüber einer konventionellen Toilettenspülung, verzögert ist.A cistern with two separate inlets was therefore described in German Offenlegungsschrift 28 08 656. However, this facility lacks the real switch from domestic water to drinking water; only a larger through-hole in the hot water supply causes a preferred filling of the toilet cistern with hot water. The disadvantages lie in the fact that tricewater is always supplied when the hot water supply is fully functional and that when the hot water supply fails, the filling of the toilet cistern with drinking water is significantly delayed compared to conventional toilet flushing.

Die deutsche Offenlegungsschrift 42 32 581 offenbart einen Auffangbehälter für Waschmaschinenwasser mit einer geregelten Zuführung zum Toilettenkasten. Diese Einrichtung setzt eine Erhebliche Aufmerksamkeit und Verantwortungsbewußtsein des Bedieners voraus, da dieser durch Einstecken des Abwasserschlauches der Waschmaschine in verschiedene Öffnung, die Auffüllung des Auffangbehälters genauestens überwachen muß. Durch einen Schwimmer im Auffangbehälter wird mittels einer Schnur das Trinkwasserventil geöffnet oder geschlossen. Reißt diese Schnur kann Abwasser in die Trinkwasserzuleitung gelangen, ein Risiko, welches wie schon erwähnt, seitens der Wasserwerke nicht hingenommen wird.German Offenlegungsschrift 42 32 581 discloses a collecting container for washing machine water with a regulated supply to the toilet box. This device requires considerable attention and responsibility on the part of the operator, since the operator must closely monitor the filling of the collecting container by inserting the sewage hose of the washing machine into different openings. The drinking water valve is opened or closed by means of a cord by a float in the collecting container. If this cord breaks, waste water can get into the drinking water supply line, a risk which, as already mentioned, is not accepted by the waterworks.

Die Erfindung hat sich die Aufgabe gestellt eine Toilettenspüleinrichtung mit automatischer Umschaltung zwischen zwei Zuläufen zu schaffen, die rein mechanisch, mit geringen baulichen Aufwand und störunanfällig die Auflagen der Wasserwerke erfüllt.The invention has set itself the task of creating a toilet flushing device with automatic switching between two inlets, which meets the requirements of the waterworks purely mechanically, with little construction effort and not susceptible to faults.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Hauptanspruches gelöst.The object is achieved by the features of the main claim.

Nachfolgend wird die Funktionsweise der erfindungsgemäßen Toilettenspüleinrichtung, bei der ein automatisches Umschalten auf Trinkwasser erfolgt, wenn der Brauchwasserkreislauf ausfällt, beschrieben.The mode of operation of the toilet flushing device according to the invention, in which there is an automatic switchover to drinking water when the process water circuit fails, is described below.

In die Brauchwasserleitung Z 2 ist ein Ventil V eingebaut, dessen Kolben K entgegen der Federkraft F oder der Gewichtskraft G vom Druck des Brauchwassers beaufschlagt wird. Die Federkraft F ist mittels Stellrad S variierbar, während das auf einer Hebelvorrichtung H angeordnete Gewicht G ebenfalls mittels Stellrad S verschoben wer den kann, so daß eine Feinregulierung der Rückstellkraft des Ventils V erfolgt. Die Kolbenstange KS kann -wie schematisch dargestellt- als Schieber ausgebildet sein, so daß die Trinkwasserleitung Z 1 je nach Stellung des Kolbens K geöffnet oder geschlossen ist. (Fig.1 bis 4)
Durch den Wasserdruck in der Brauchwasserleitung Z 2 wird das Ventil V betätigt, das den Zufluß von Trinkwasser aus der Trinkwasserleitung Z 1 unterbindet, wie in Fig. 2 und 4 beispielhaft gezeigt.A valve V is installed in the service water line Z 2, the piston K of which is acted upon by the pressure of the service water against the spring force F or the weight force G. The spring force F can be varied by means of the adjusting wheel S, while the weight G arranged on a lever device H can also be shifted by means of the adjusting wheel S, so that the restoring force of the valve V can be finely adjusted. The piston rod KS can - as shown schematically - be designed as a slide, so that the drinking water line Z 1 is opened or closed depending on the position of the piston K. (Fig. 1 to 4)
The valve V is actuated by the water pressure in the service water line Z 2, which prevents the inflow of drinking water from the drinking water line Z 1, as shown by way of example in FIGS. 2 and 4.

Der Kolben K des Ventils V wird, wenn der Wasserdruck in der Brauchwasserleitung Z 2 sinkt, durch die Feder F bzw. das Gewicht G entgegen dem Wasserdruck in der Brauchwasserleitung Z 2 derart bewegt, daß bei fehlendem Brauchwasserdruck die Trinkwasserleitung Z 1 geöffnet wird.
Der Kolben K ist breit genug dimensioniert, damit eine ausreichend große Kraft zur Betätigung des Ventils V vorliegt. Mit dem Stellrad S kann die Federkraft F bzw. Gewichtskraft G feinreguliert werden, um eine Anpassung an die lokal vorliegenden Wasserdrücke der beiden Leitungen Z 1 und Z 2 zu ermöglichen.The piston K of the valve V is moved by the spring F or the weight G against the water pressure in the service water line Z 2 when the water pressure in the service water line Z 2 drops such that the drinking water line Z 1 is opened in the absence of service water pressure.
The piston K is dimensioned wide enough so that there is a sufficiently large force to actuate the valve V. The spring force F or weight force G can be finely regulated with the adjusting wheel S in order to enable adaptation to the locally present water pressures of the two lines Z 1 and Z 2.

In den Fig.1 bis 4 ist das Ventil V in geöffneten und geschlossenen Zustand dargestellt. Diese Einrichtung kann neben dem Einsatz in Toilettenspülkästen T auch bei -nicht näher dargestellten- Druckspüleinrichtungen verwendet werden. Hierzu wird die erfindungsgemäße Einrichtung den allgemein bekannten Druckspüleinrichtungen vorgeschaltet.1 to 4, the valve V is shown in the open and closed state. In addition to use in toilet cisterns T, this device can also be used with pressure flushing devices (not shown). For this purpose, the device according to the invention is connected upstream of the generally known pressure flushing devices.

Die Druckspüleinrichtung muß dabei so ausgebildet sein, daß bei Betätigung der Spültaste beide Leitungen Z1 und Z 2 gleichzeitig geöffnet werden, aber durch die vorgeschaltete erfindungsgemäße Einrichtung nur jeweils eine Leitung Z 1 oder Z 2 Wasser liefert.The pressure flushing device must be designed so that when the flush button is pressed both lines Z1 and Z 2 are opened at the same time, but only one line Z 1 or Z 2 supplies water through the upstream device according to the invention.

Wie in den Figuren 5 und 6 dargestellt, werden zwei Schwimmerventilsysteme, für die Trinkwassersteuerung S 1 und für die Brauchwassersteuerung S 2, dergestalt in einem Toilettenspülkasten T angeordnet, daß bei absinkendem Wasserstand das Brauchwasserschwimmerventil S 2 vor dem Trinkwasserschwimmerventil S 1 anspricht.
Das zufließende Brauchwasser verhindert ein Absinken des Schwimmerventils S 1, welches die Trinkwasserzufuhr regelt.As shown in FIGS. 5 and 6, two float valve systems, for the drinking water control S 1 and for the industrial water control S 2, are arranged in a toilet cistern T such that when the water level drops, the industrial water float valve S 2 responds before the drinking water float valve S 1.
The inflowing process water prevents the float valve S 1 from sinking, which regulates the drinking water supply.

Dazu ist innerhalb des Toilettenspülkastens T ein Teilbereich durch feste Wände abgetrennt, so daß ein Behälter B entsteht, der jedoch nach oben hin offen bleibt.
Innerhalb dieses Behälters B befindet sich das Schwimmerventil S 1, welches die Trinkwasserleitung Z 1 öffnet und schließt, während das im Toilettenspülkasten T angebrachte Schwimmerventil S 2 die Brauchwasserleitung Z 2 öffnet und schließt.For this purpose, a portion of the toilet cistern T is separated by solid walls, so that a container B is created, but remains open at the top.
Within this container B is the float valve S 1, which opens and closes the drinking water line Z 1, while the float valve S 2 installed in the toilet cistern T 2 opens and closes the process water line Z 2.

Bei geöffnetem Schwimmerventil S 2 erfolgt der Zufluß aus der Brauchwasserleitung Z 2 in den Behälter B, dessen Drosselöffnung A den Abfluß von Wasser in den nicht abgetrennten Teil des Toilettenspülkastens T erlaubt.
Diese Drosselöffnung A ist so dimensioniert, daß bei zufließendem Brauchwasser mehr Wasser zufließt als abfließt.When the float valve S 2 is open, the inflow from the service water line Z 2 into the container B, the throttle opening A of which allows the outflow of water into the non-separated part of the toilet cistern T.
This throttle opening A is dimensioned in such a way that more water flows in than flows out when the process water flows in.

Desweiteren ist die Zufuhr des Brauchwassers so geregelt, daß das Schwimmerventil S 2 bereits bei einem geringfügig höherem Wasserstand öffnet, als das Trinkwasserschwimmerventil S 1. Dieses wird beispielsweise durch eine etwas erhöhte Anbringung im Toilettenspülkasten T erreicht.Furthermore, the supply of the process water is regulated so that the float valve S 2 opens at a slightly higher water level than the drinking water float valve S 1.

Erfolgt bei vollem Toilettenspülkasten T die Entleerung durch Betätigung der Spülung, so können zwei Fälle des Wiederauffüllens unterschieden werden, nämlich:If the toilet cistern T is full and is emptied by actuating the flush, two cases of refilling can be distinguished, namely:

1. Brauchwasser vorhanden1. Process water available

In diesem Fall setzt bei fallendem Wasserstand im Toilettenspülkasten T die Wasserzufuhr aus der Brauchwasserleitung Z 2 ein, die in den Behälter B fließt. Dieser Zufluß bewirkt, daß im Behälter B ein weiterer Abfall des Wasserpegels unterbleibt, so daß die Trinkwasserzufuhr nicht einsetzt. Der entleerte Toilettenspülkasten T wird so lange mit Brauchwasser aufgefüllt, bis das Brauchwasser-Schwimmerventil S 2 die Zufuhr abschaltet. Das Brauchwasser gelangt dabei sowohl durch Überlauf als auch durch die Drosselöffnung A in den Toilettenspülkasten T.In this case, when the water level in the toilet cistern T drops, the water supply from the service water line Z 2, which flows into the container B, begins. This influx has the effect that a further drop in the water level does not occur in the container B, so that the drinking water supply does not start. The emptied toilet cistern T is filled with process water until the process water float valve S 2 switches off the supply. The process water reaches the toilet cistern T through both the overflow and the throttle opening A.

2. Brauchwasser nicht vorhanden2. Process water not available

Bei fallendem Wasserstand im Toilettenspülkasten T wird auch der Behälter B über die Drosselöffnung A entleert, so daß sich das Trinkwasser-Schwimmerventil S 1 öffnet. Der entleerte Toilettenspülkasten T wird nunmehr über die Trinkwasserleitung Z 1 gefüllt, wobei das einlaufende Wasser über die Drosselöffnung A oder durch Überlauf in den Behälter B gelangt und das Trinkwasser-Schwimmerventil S 1 schließt.When the water level in the toilet cistern T drops, the container B is also emptied via the throttle opening A, so that the drinking water float valve S 1 opens. The emptied toilet cistern T is now filled via the drinking water line Z 1, the incoming water entering the container B via the throttle opening A or through an overflow and closing the drinking water float valve S 1.
