Abstract

PCT No. PCT/EP92/00611 Sec. 371 Date Oct. 19, 1993 Sec. 102(e) Date Oct. 19, 1993 PCT Filed Mar. 19, 1992 PCT Pub. No. WO92/18713 PCT Pub. Date Oct. 29, 1992.A discharge system for discharging wastes from a unit producing such wastes, such as a toilet, is disclosed. The system includes a device for creating a partial vacuum, an intermediate container and a collecting basin connected together by pipelines and valves in an arrangement which permits the use of an immediate container having a relatively small volume thereby permitting the use of a smaller vacuum pump. The discharge system is particularly useful for rail-bound vehicles and overland buses.

Description

Die Erfindung bezieht sich auf ein Klosett mit einem Klosettbecken, insbesondere in einem Fahrzeug, mit einer Ejektor-Vorrichtung zum Erzeugen von Unterdruck, einem Zwischenbehälter und einem Sammelbehälter, die über Rohrleitungen mit Ventilen miteinander verbunden sind, wobei die Ejektor-Vorrichtung zur Erzeugung von Unterdruck den Zwischenbehälter unter Unterdruck setzt, wobei bei geöffnetem Ventil in der Leitung von dem Klosettbecken eine Ablaufmasse in den Zwischenbehälter gesaugt und von dort in den Sammelbehälter gedrückt wird,
Bei einem derartigen bekannten Ablaufsystem (DE-OS 39 32 893) werden dem Sammelbehälter und dem Zwischenbehälter Luft bzw. Gase entnommen und in einen Druckbehälter gegeben. Weiterhin soll der Druckbehälter zusammen mit dem Vakuum im Zwischen- und Sammelbehälter dafür sorgen, daß die Ablaufmasse in den Sammelbehälter gelangt. Der Vakuumerzeuger und der Druckbehälter können jedoch nicht ausreichend groß dimensioniert werden, um dies zu erreichen, so daß Bedenken bestehen, ob das bekannte System überhaupt funktioniert. Da der Sammelbehälter ein relativ großes Volumen hat, müßte auch die Vakuumpumpe relativ groß ausgebildet sein. In jedem Fall würde aufgrund dieses großen Volumens das Klosett - wenn überhaupt - dann nur in relativ großen Zeitabständen benutzt werden können. Bei dem bekannten System sind darüber hinaus noch Einrichtungen erforderlich, die das gesamte System nicht nur umständlich und störanfällig sondern auch sehr aufwendig machen.The invention relates to a lavatory with a lavatory basin, in particular in a vehicle, with an ejector device for generating negative pressure, an intermediate container and a collecting container which are connected to one another via pipes with valves, the ejector device for generating negative pressure puts the intermediate container under negative pressure, an outlet mass being sucked into the intermediate container from the toilet bowl when the valve in the line is open and pressed into the collecting container from there,
In such a known drain system (DE-OS 39 32 893), air or gases are removed from the collecting container and the intermediate container and placed in a pressure container. Furthermore, the pressure container together with the vacuum in the intermediate and collecting container should ensure that the drainage mass gets into the collecting container. However, the vacuum generator and the pressure vessel cannot be dimensioned large enough to achieve this, so that there are concerns as to whether the known system works at all. Since the collecting container has a relatively large volume, the vacuum pump would also have to be of relatively large design. In any case, because of this large volume, the toilet would - if at all - only be able to be used at relatively large intervals. In the known system, facilities are also required which not only make the entire system cumbersome and prone to failure, but also very expensive.

Der Erfindung liegt die Aufgabe zugrunde, ein Klosett der eingangs genannten Art einfacher auszugestalten und darüber hinaus auch hinsichtlich des technisch erforderlichen Aufwands zu vereinfachen.The invention has for its object to simplify a toilet of the type mentioned and in addition to simplify the technically necessary effort.

Erreicht wird dies durch die in dem kennzeichnenden Teil des Anspruchs angegebenen Merkmale.This is achieved by the features specified in the characterizing part of the claim.

Zunächst ist bedeutend, daß eine relativ kleine vakuumerzeugende Einrichtung verwendet werden kann, da lediglich das relativ kleine Volumen des Zwischenbehälters, es handelt sich hierbei um einige Liter, evakuiert werden muß. Ist der Zwischenbehälter genügend unter Unterdruck gesetzt worden, so kann Ablaufmasse angesaugt und durch Einleitung von Druckluft aus dem Zwischenbehälter heraus in den Sammelbehälter gedrückt werden. Außer dem geringeren Aufwand im Hinblick auf die Vakuumpumpe kann beim Klosett gemäß der Erfindung dieses in relativ kleinen Zeiträumen benutzt werden.First of all, it is important that a relatively small vacuum-generating device can be used, since only the relatively small volume of the intermediate container, which is a few liters, has to be evacuated. If the intermediate container has been sufficiently pressurized, drainage mass can be sucked in and pressed into the collection container by introducing compressed air from the intermediate container. In addition to the less effort with regard to the vacuum pump, the toilet according to the invention can be used in relatively short periods of time.

Gemäß der Erfindung befinden sich, bis auf den Sammelbehälter und die dorthin führende Leitung, alle Leitungen, alle Ventile sowie der Zwischenbehälter und die Vakuumeinrichtung in unmittelbarer Nähe zum Klosettbecken, d.h. im Sitz oder unterhalb der Schüssel. Dies ist von besonderer Bedeutung, wenn es um Installationen in Fahrzeugen geht, bei denen von Hause aus Raumprobleme auftreten.According to the invention, apart from the collecting container and the line leading there, all lines, all valves as well as the intermediate container and the vacuum device are in the immediate vicinity of the toilet bowl, i.e. in the seat or below the bowl. This is of particular importance when it comes to installations in vehicles where there are problems with space at home.

Die Erfindung ist insbesondere einsatzfähig für schienengebundene Fahrzeuge, aber auch beispielsweise für Überlandbusse.The invention can be used in particular for rail-bound vehicles, but also, for example, for interurban buses.

Die Erfindung wird anhand der Zeichnung beispielsweise erläutert.The invention is explained for example with reference to the drawing.

Die einzige Figur der Zeichnung zeigt schematisch ein Klosett gemäß der Erfindung.The only figure of the drawing shows schematically a toilet according to the invention.

Mit 1 ist in der Figur ein Klosettbecken gezeigt, welches mit einem nicht näher erläuterten bekannten Wasserspülsystem versehen ist. Am Auslaufende der Klosettschüssel 1 befindet sich ein Ventil 5, welches über eine Leitung 7 zu einem Zwischenbehälter 17 führt, in dem eine Vakuumeinrichtung in unmittelbarer räumlicher Nähe oder über eine kurze Leitung mit Ventil angeordnet ist. Die Vakuumeinrichtung 6 ist so ausgestaltet, daß der Innenraum des Zwischenbehälters 17 sehr schnell evakuiert werden kann. Die abgesaugten Gase können auch in den Sammelbehälter 9 gebracht werden. Als Vakuumeinrichtung kommt ein Ejektor in Frage, der über die ohnehin vorhandene Drucklufteinreichtung betätigt wird.1 with a toilet bowl is shown in the figure, which is provided with a known water rinsing system not explained in detail. At the outlet end of the toilet bowl 1 there is a valve 5 which leads via a line 7 to an intermediate container 17 in which a vacuum device is arranged in the immediate vicinity or via a short line with a valve. The vacuum device 6 is designed so that the interior of the intermediate container 17 can be evacuated very quickly. The extracted gases can also be brought into the collecting container 9. An ejector can be used as a vacuum device, which is actuated via the compressed air device, which is already present.

Weiterhin führt in den Sammelbehälter 17 über ein Ventil 20 eine Leitung 15, die an das Druckluftnetz oder einen Drucklufterzeuger angeschlossen ist.Furthermore, a line 15 leads into the collecting container 17 via a valve 20, which line is connected to the compressed air network or a compressed air generator.

In der Zeichnung sind Ansteuerleitungen für die Ventile sowie Meß- und Befehlsleitungen (in ununterbrochenen Linien) schematisch angegeben, die zu einer nicht gezeigten Steuerung führen.In the drawing, control lines for the valves and measuring and command lines (in uninterrupted lines) are schematically indicated, which lead to a control, not shown.

Soll aus der Klosettschüssel 1 Ablaufmasse entfernt werden, so wird zunächst der eigentliche Spülvorgang eingeleitet, wobei das Ventil 5 geschlossen ist. Zuvor hat die Vakuumpumpe 6 schon den Innenraum des Zwischenbehälters 17 evakuiert, und die Ventile 20 und 8 sind geschlossen.If drainage mass is to be removed from the toilet bowl 1, the actual flushing process is first initiated, the valve 5 being closed. The vacuum pump 6 has already evacuated the interior of the intermediate container 17, and the valves 20 and 8 are closed.

Als nächstes wird das Ventil 5 geöffnet, so daß die Ablaufmasse über die Leitung 7 zufolge des Unterdrucks in den Zwischenbehälter 17 gelangt.Next, the valve 5 is opened so that the drainage mass reaches the intermediate container 17 via the line 7 due to the negative pressure.

Sodann wird das Ventil 5 geschlossen und die Ventile 8 und 20 werden geöffnet, so daß die Druckluft die Ablaufmasse aus dem Zwischenbehälter 17 in den Sammelbehälter 9 drückt.Then the valve 5 is closed and the valves 8 and 20 are opened so that the compressed air presses the drainage mass from the intermediate container 17 into the collecting container 9.

Der Sammelbehälter 9 kann ein Volumen von 100 Litern oder mehr haben. Der Zwischenbehälter 17 hingegen kann beispielsweise einen Inhalt von einigen Litern haben. Zum Spülvorgang selbst werden bei dem Klosett gemäß der Erfindung nur Bruchteile eines Liters an Spülwasser benötigt.The collecting container 9 can have a volume of 100 liters or more. The intermediate container 17, however, can have a content of a few liters, for example. For the flushing process itself, only a fraction of a liter of flushing water is required in the toilet according to the invention.

Bei der bevorzugten Ausführungsform der vorliegenden Erfindung wird das bei Schienenfahrzeugen ohnehin vorhandene Druckluftsystem zweckmäßigerweise herangezogen, wobei keine Pumpe mit mechanisch beweglichen Teilen erforderlich ist, sondern ein Ejektor eingesetzt werden kann. Dies bedeutet, daß an Stelle von mechanischen Pumpen lediglich Ventile erforderlich sind. Darüber hinaus stellt das Bordnetz von schienengebundenen Fahrzeugen einen relativ hohen Druck zur Verfügung, so daß einerseits die gewünschte hohe Vakuumleistung möglich ist und andererseits auch der Fördervorgang der Ablaufmasse aus dem Zwischenbehälter in den Ablaufbehälter zuverlässig durchgeführt werden kann. Schließlich kommt noch hinzu, daß relativ wenig Spülwasser benötigt wird, was insbesondere bei frostgefährdeten Räumen von Bedeutung ist.In the preferred embodiment of the present invention, the compressed air system already present in rail vehicles is expediently used, it not being necessary to use a pump with mechanically movable parts, but an ejector can be used. This means that only valves are required instead of mechanical pumps. In addition, the on-board network of rail-bound vehicles provides a relatively high pressure, so that on the one hand the desired high vacuum output is possible and on the other hand the discharge process of the drain mass from the intermediate container into the drain container can be carried out reliably. Finally, there is also the fact that relatively little rinse water is required, which is particularly important in rooms where there is a risk of frost.
