Abstract

A toilet system which can be rinsed by a rinsing device. A pipe is connected to the toilet pan and leads to a sanitation pipe. Means are provided for transporting a suction material from the toilet pan into the pipe and into the sanitation pipe. Said means comprise two valves which are arranged in the pipe and a pressure chamber is disposed in-between. In order to suction the suction material from the toilet pan, low pressure is produced in the pressure chamber and used to transport said suctioned material. The pressure chamber is embodied as a piston cylinder and the piston is connected to a controllable drive in order to produce the high and low pressure. The inventive toilet system enables rinsing to occur using a very small amount of water and which can be adapted to different toilet pans.

Description

Die Erfindung betrifft eine Toilettenanlage mit einer Toilettenschüssel gemäss Oberbegriff des Anspruchs 1.The invention relates to a toilet installation with a toilet bowl according to the preamble of claim 1.

Die gattungsbildende US-A-2,865,028 offenbart eine Toilettenanlage für Mobilheime, bei der mit einem Kolbenzylinder Absaugmasse von der Toilettenschüssel ansaugbar und in eine Entsorgungsleitung ausstossbar ist. Die Betätigung des Kolbenzylinders erfolgt von Hand an einem Hebel, der mit dem Kolben verbunden ist. In Strömungsrichtung gesehen befindet sich vor und nach dem Kolbenzylinder je ein Klappenventil. Das erste Klappenventil öffnet sich beim Erzeugen eines Unterdrucks im Kolbenzylinder und schliesst, wenn in diesem ein Überdruck erzeugt wird. Als Antrieb des Kolbens ist ein Hebel vorgesehen, der von Hand betätigt werden muss.The generic US-A-2,865,028 discloses a toilet system for mobile homes, in which with a piston cylinder suction mass from the toilet bowl can be sucked and ejected into a disposal line. The operation of the piston cylinder is done by hand on a lever which is connected to the piston. Seen in the flow direction is located before and after the piston cylinder ever a flapper valve. The first flap valve opens when generating a negative pressure in the piston cylinder and closes when an overpressure is generated in this. As a drive of the piston, a lever is provided, which must be operated by hand.

Die Toilettenanlagen, bei denen mittels Vakuum die Absaugmasse abgesaugt wird, sind bisher vor allem in Fahrzeugen, beispielsweise in Bahnwagen und Wohnmobilen bekannt. Beispielsweise offenbart die WO 92/18713 eine Toilettenanlage, bei der eine Vorrichtung zur Erzeugung von Unterdruck, einen Zwischenbehälter und einen Sammelbehälter aufweist. Die genannte Vorrichtung evakuiert zur Erzeugung des Unterdrucks den Zwischenbehälter, sodass bei einem geöffneten Ventil in einer Leitung die Absaugmasse in den Zwischenbehälter angesaugt wird. Sammelbehälter erfordern viel Platz und müssen geleert werden. Sie sind in der Haustechnik nicht erwünscht.The toilet facilities, in which the vacuum is sucked by vacuum, have been known, especially in vehicles, such as railway carriages and mobile homes. For example, the WO 92/18713 a toilet installation, in which a device for generating negative pressure, an intermediate container and a collecting container has. Said device evacuates the intermediate container to generate the negative pressure, so that when an open valve in a line, the suction mass is sucked into the intermediate container. Storage tanks require a lot of space and must be emptied. They are not desired in the building services.

Die EP 0 887 478 offenbart eine Toilettenanlage, bei der ebenfalls ein Tank vorgesehen ist. Mittels einer Membranpumpe wird im Tank ein Teilvakuum erzeugt, durch das eine Absaugwirkung erzeugt wird.The EP 0 887 478 discloses a toilet facility in which a tank is also provided. By means of a diaphragm pump, a partial vacuum is generated in the tank, through which a suction effect is generated.

Die EP 0 806 527 offenbart eine Spülvorrichtung, die ein hohles, becherförmiges Verschlusselement aufweist. Das Verschlusselement arbeitet mit einer Eingangsöffnung und einer Ausgangsöffnung zusammen, die jeweils beide offen oder geschlossen sind.The EP 0 806 527 discloses a flushing device having a hollow, cup-shaped closure element. The closure member cooperates with an input port and an exit port, each of which is open or closed.

Toilettenanlagen mit jeweils einem Sammeltank sind zudem aus der EP 0 704 372 und EP 1 022 399 bekannt geworden.Toilet facilities, each with a collection tank are also from the EP 0 704 372 and EP 1 022 399 known.

Die EP 0 763 633 A1 offenbart eine Absaugtoilette, die in der Ablaufleitung zwischen zwei Ventilen eine Druckkammer besitzt. Durch einen Unterdruck in dieser Kammer wird beim Öffnen eines eingangsseitigen Ventils Absaugmasse von der Toilettenschüssel durch die Ablaufleitung in diese Kammer gesaugt. Nach einem Umschalten der beiden Ventile wird mittels Druck die Absaugmasse von der Kammer in eine weitere Leitung gepresst. Zum Evakuieren der Kammer ist eine Saugstrahlpumpe vorgesehen, die mit Druckluft betrieben wird. Ein Faltenbalg in der Druckkammer bildet eine flexible Membran und dient als Dichtungsmittel und soll verhindern, dass schlechte Luft aus der Ablaufleitung nach aussen gelangen kann. Bei der Erzeugung eines Unterdruckes wird eine Feder gespannt, die beim Entspannen einen Druck aufbaut. Bei dieser Toilettenanlage besteht die Schwierigkeit, dass das Abdichten der Kammer mittels einer flexiblen Membran aufwendig und störungsanfällig ist. Der Aufbau eines Unterdruckes erfordert mittels einer Saugstrahlpumpe vergleichsweise viel Zeit. Zudem ist der erreichbare Druck zum Ausstossen der Absaugmasse aus der Kammer sehr begrenzt. In der Praxis dürfte sich diese Toilettenanlage kaum bewähren.The EP 0 763 633 A1 discloses a suction toilet having a pressure chamber in the drain line between two valves. By a negative pressure in this chamber, suction is sucked from the toilet bowl through the drain line into this chamber when opening an input-side valve. After switching over the two valves, the suction mass is pressed by the chamber into another line by means of pressure. To evacuate the chamber, a suction jet pump is provided, which is operated by compressed air. A bellows in the pressure chamber forms a flexible membrane and serves as a sealant and is intended to prevent poor air from the drain line can go outside. When generating a negative pressure, a spring is tensioned, which builds up a pressure while relaxing. In this toilet system, there is the difficulty that the sealing of the chamber by means of a flexible membrane is complicated and prone to failure. The construction of a negative pressure requires comparatively much time by means of a suction jet pump. In addition, the achievable pressure for ejecting the Absaugmasse from the chamber is very limited. In practice, this toilet system is unlikely to prove itself.

Der Erfindung liegt die Aufgabe zugrunde, eine Toilettenanlage der genannten Art zu schaffen, die bei geringem Wasserverbrauch funktionssicher und dauerhaft ist.The invention has for its object to provide a toilet system of the type mentioned, which is reliable and durable with low water consumption.

Die Aufgabe ist bei einer gattungsgemässen Toilettenanlage gemäss Anspruch 1 gelöst. Bei der erfindungsgemässen Toilettenanlage wird der Unter- bzw. Überdruck durch Bewegen des Kolbens erzeugt. Dies ermöglicht einen sehr schnellen Aufbau eines Unterdrucks, beispielsweise innerhalb eines Bruchteils einer Sekunde. Ein Überdruck kann ebenfalls sehr schnell und zudem mit einem Überdruck über 1 bar, beispielsweise 2 bar erzeugt werden. Ein weiterer Vorteil der erfindungsgemässen Toilettenanlage wird darin gesehen, dass der Hub und damit das absaugbare Volumen der Absaugmasse genau einstellbar ist. Es ist auch möglich, nacheinander zwei oder mehr Absaugzyklen durchzuführen. Damit ist mit sehr wenig Wasser ein sauberer Spülvorgang möglich. Der Kolben des Kolbenzylinders kann hier selbst als Dichtungsmittel dienen, das ein Entweichen schlechter Luft nach aussen verhindert. Eine flexible Membran oder dergleichen ist somit nicht erforderlich. Die Bewegung des Kolbens erfolgt gemäss einer Weiterbildung der Erfindung mittels eines Elektromotors. Dies ermöglicht in Verbindung mit einer Steuervorrichtung eine exakte und genaue Steuerung des Absaug- bzw. Ausstossvorgangs. Diese Vorgänge sind zudem einstellbar und an die jeweilige Toilettenschüssel anpassbar.The object is achieved in a generic toilet system according to claim 1. In the toilet system according to the invention, the underpressure or overpressure is generated by moving the piston. This allows a very rapid build-up of a negative pressure, for example within a fraction of a second. An overpressure can also be generated very quickly and moreover with an overpressure of more than 1 bar, for example 2 bar. Another advantage of the inventive toilet system is seen in the fact that the stroke and thus the absorbable volume of the suction mass is precisely adjustable. It is also possible to perform successively two or more suction cycles. This makes a clean rinse possible with very little water. The piston of the piston cylinder itself can serve as a sealant, which prevents the escape of bad air to the outside. A flexible membrane or the like is thus not required. The movement of the piston takes place according to an embodiment of the invention by means of an electric motor. This, in conjunction with a control device, enables accurate and accurate control of the extraction process. These processes are also adjustable and adaptable to the respective toilet bowl.

Die Toilettenanlage weist gemäss den Fig. 1 und 2 eine Toilettenschüssel 5 auf, die trichterförmig ausgebildet und einen unteren Ausgang 5a aufweist. Dieser Ausgang 5a ist jedoch vergleichsweise klein und weist einen Querschnitt von beispielsweise 30 mm2 auf. An der Unterseite dieses Ausganges 5a ist in einer Leitung 29 eine Saugleitung 6 angeschlossen, die ebenfalls einen vergleichsweise kleinen Querschnitt aufweist. Die Toilettenschüssel 5 ist mit einer Spülvorrichtung 1 spülbar und weist ein Spülrohr 3 auf, durch das Spülwasser in das Innere der Toilettenschüssel 5 einleitbar ist. Die Spülvorrichtung 1 kann ein Spülkasten oder eine andere geeignete Spülvorrichtung sein. Wesentlich ist jedoch, dass vergleichsweise wenig Spülwasser verwendet wird, beispielsweise weniger als ein Liter. Die Auslösung der Spülung erfolgt an einer Taste 2 oder an einer anderen geeigneten Auslösevorrichtung. Denkbar ist hier auch eine berührungslose oder automatische Auslösung.The toilet has according to the Fig. 1 and 2 a toilet bowl 5, which is funnel-shaped and has a lower outlet 5a. However, this output 5a is comparatively small and has a cross section of, for example, 30 mm 2 . At the bottom of this output 5a, a suction line 6 is connected in a line 29, which also has a comparatively small cross-section. The toilet bowl 5 can be flushed with a flushing device 1 and has a flushing pipe 3 through which flushing water into the interior of the toilet bowl 5 can be introduced. The flushing device 1 may be a cistern or other suitable flushing device. It is essential, however, that comparatively little rinsing water is used, for example less than one liter. The triggering of the flushing takes place on a key 2 or on another suitable triggering device. Conceivable here is also a non-contact or automatic triggering.

In der Saugleitung 6 ist ein Ventil 7 angeordnet, das in einem geschlossenen Zustand die Saugleitung 6 absperrt und in geöffnetem Zustand den Durchgang zu einer Kammer 12 eines Kolbenzylinders 8 freigibt. Das Ventil 7 wird über eine Signalleitung 24 von einer Steuervorrichtung 26 gesteuert.In the suction line 6, a valve 7 is arranged, which shuts off the suction line 6 in a closed state and in the open state, the passage to a chamber 12 of a piston cylinder 8 releases. The valve 7 is controlled by a control device 26 via a signal line 24.

Der Kolbenzylinder 8 weist ein Gehäuse 9 auf, in dem ein Kolben 10 in den Richtungen des Doppelpfeiles 19 begrenzt verschiebbar ist. Der Kolben 10 unterteilt das Gehäuse 9 in eine untere Kammer 12 und in eine obere Kammer 13. Der Kolben 10 dichtet diese beiden Kammern 12 und 13 gegeneinander ab. Dazu ist an der Aussenseite des Kolbens 10 eine umlaufende Dichtung 10a angeordnet. Der Kolben 10 wird mit einem Motor 14, beispielsweise einem Elektromotor bewegt und ist mit dem Kolben 10 über eine Kolbenstange 11 verbunden, die wie ersichtlich mit dem einen Ende aus dem Gehäuse 9 herausragt. Bei der Bewegung des Kolbens 10 wird aus der Oberkammer 13 mittels Ventilen 22 und 23 Luft in die Umgebung ausgestossen, bzw. Frischluft aus der Umgebungsluft angezogen. Die Ventile 22 und 23 können einfache Klappenventile sein. Die Stromversorgung des Motors 14 erfolgt über eine Stromleitung 15. Über diese Leitung wird ebenfalls die Steuervorrichtung 26 versorgt. Die Steuervorrichtung 26 kann auch im Motor 14 integriert sein.The piston cylinder 8 has a housing 9, in which a piston 10 is limitedly displaceable in the directions of the double arrow 19. The piston 10 divides the housing 9 into a lower chamber 12 and into an upper chamber 13. The piston 10 seals these two chambers 12 and 13 from each other. For this purpose, a circumferential seal 10a is arranged on the outside of the piston 10. The piston 10 is connected to a motor 14, for example an electric motor moves and is connected to the piston 10 via a piston rod 11, which protrudes as shown with one end of the housing 9. During the movement of the piston 10 air is expelled from the upper chamber 13 by means of valves 22 and 23 into the environment, or fresh air is attracted from the ambient air. The valves 22 and 23 may be simple flapper valves. The power supply of the motor 14 via a power line 15. Via this line, the control device 26 is also supplied. The control device 26 may also be integrated in the engine 14.

Die untere Kammer 12 weist einen Ausgang 12a auf, der wie ersichtlich an der untersten Stelle der unteren Kammer 12 angeordnet ist und an dem eine Druckleitung 17 angeschlossen ist. Die Druckleitung 17 kann ein flexibler Schlauch oder eine feste Rohrleitung sein. In der Nähe des Ausganges 12a befindet sich ein weiteres Ventil 16, das über eine Signalleitung 25 von der Steuervorrichtung 26 gesteuert ist. In einem Zustand ist der Durchgang zur Druckleitung 17 verschlossen und im anderen Zustand frei. Die untere Kammer 12 bildet eine Druckkammer und diese kann in die Toilettenschüssel 5 integriert sein und mit dieser eine Einheit bilden.The lower chamber 12 has an outlet 12a which, as can be seen, is located at the lowest point of the lower chamber 12 and to which a pressure line 17 is connected. The pressure line 17 may be a flexible hose or a fixed pipe. In the vicinity of the output 12a, there is another valve 16, which is controlled by the control device 26 via a signal line 25. In one state, the passage to the pressure line 17 is closed and free in the other state. The lower chamber 12 forms a pressure chamber and this can be integrated into the toilet bowl 5 and form a unit with this.

Die Druckleitung 17 weist einen Querschnitt auf, der in wesentlichen dem Querschnitt der Saugleitung 6 entsprechen kann. Dieser Querschnitt ist somit ebenfalls vergleichsweise klein und kann etwa mit demjenigen eines Gartenschlauches verglichen werden. Er kann vergleichsweise lang, beispielsweise mehrere Meter lang sein und führt gemäss Fig. 1 zu einem Fallrohr einer Entsorgungsleitung 18. Vorzugsweise weist die Druckleitung 17 ein vorderes Ende 17a auf, das vergleichsweise tief, beispielsweise mehrere Meter in eine Entsorgungsleitung 18 hineinragt. Die Druckleitung 17 ist beispielsweise durch einen seitlichen Stutzen 18a in die Entsorgungsleitung 18 eingeführt.The pressure line 17 has a cross-section which may correspond substantially to the cross-section of the suction line 6. This cross-section is therefore also comparatively small and can be compared with that of a garden hose. It can be comparatively long, for example several meters long and leads according to Fig. 1 to a downpipe of a disposal line 18. Preferably, the pressure line 17 has a front end 17a which protrudes comparatively deep, for example several meters into a disposal line 18. The pressure line 17 is for example by a lateral neck 18a introduced into the disposal line 18.

Nachfolgend wird die Arbeitsweise der erfindungsgemässen Toilettenanlage erläutert.The operation of the toilet system according to the invention will be explained below.

Der Ruhezustand der Toilettenanlage ist in Fig. 2 gezeigt. Die Ventile 7 und 16 sind geschlossen und der Kolben 10 befindet sich in der gezeigten unteren Stellung. Bei der Benutzung der Toilettenanlage kann die Spülvorrichtung 1 für eine Vorbenetzung der Innenseite 5b der Toilettenschüssel 5 betätigt werden. Durch die Benetzung sammelt sich in der Toilettenschüssel 5 die Absaugmasse 4, welche die Saugleitung 6 bis zum Ventil 7 füllt. Durch Betätigen der Auslösetaste 2 wird eine Spülung ausgelöst. Wasser gelangt hierbei durch das Spülrohr 3 in die Toilettenschüssel 5. Die hier verwendete Wassermenge wird über die Steuerung 6, und die Signalleitung 27 gesteuert. Vorzugsweise sind eine oder mehrere Düsen vorgesehen, welche hierbei die Innenseite 5b der Toilettenschüssel besprüht bzw. besprühen.The resting state of the toilet facility is in Fig. 2 shown. The valves 7 and 16 are closed and the piston 10 is in the lower position shown. When using the toilet system, the flushing device 1 can be operated for pre-wetting the inside 5b of the toilet bowl 5. By wetting accumulates in the toilet bowl 5, the suction mass 4, which fills the suction line 6 to the valve 7. By pressing the release button 2, a purge is triggered. Water here passes through the flushing pipe 3 in the toilet bowl 5. The amount of water used here is controlled by the controller 6, and the signal line 27. One or more nozzles are preferably provided, which in this case spray or spray the inner side 5b of the toilet bowl.

Nach dem Besprühen fährt der Kolben 10 etwa in die in Fig. 4 gezeigte Stellung. Vorzugsweise wird hier die oberste Stellung nicht ganz erreicht. Da die Ventile 7 und 16 noch geschlossen sind, wird dadurch in einer Kammer 12' ein Unterdruck erzeugt, der vorzugsweise kleiner als etwa 0,5bar ist. Gleichzeitig kann über die Steuervorrichtung 16 eine weitere Spülung der Toilettenschüssel 5 ausgelöst werden. Etwa gleichzeitig wird das Ventil 7 vergleichsweise schnell und somit im wesentlichen plötzlich geöffnet. Das schnelle Öffnen kann beispielsweise durch eine hier nicht gezeigte vorgespannte Feder erfolgen. Etwa gleichzeitig wird die Spülung der Toilettenschüssel 5 unterbrochen. Die untere Kammer 12' ist so gross, dass diese etwa zur Hälfte mit Luft und zur Hälfte mit Absaugmasse 4 gefüllt ist. Beim Ansaugen der Absaugmasse 4 werden die Feststoffe durch das plötzliche Einströmen in die unter Kammer 12' verkleinert, sodass die abgesaugte Absaugmasse 4' ähnlich einer Suspension vorliegt. Die Fig. 5 zeigt mit dem Pfeil 28 die Einströmrichtung der Absaugmasse 4 in die Unterkammer 12'. Über der Absaugmasse 4' befindet sich ein Luftpolster 21, das wie oben erwähnt, etwa das halbe Volumen der unteren Kammer 12' einnimmt.After spraying, the piston 10 moves approximately in the in Fig. 4 shown position. Preferably, the uppermost position is not quite reached here. Since the valves 7 and 16 are still closed, a negative pressure is thereby generated in a chamber 12 ', which is preferably less than about 0.5 bar. At the same time, a further flushing of the toilet bowl 5 can be triggered via the control device 16. At about the same time, the valve 7 is opened relatively quickly and thus substantially suddenly. The rapid opening can be done for example by a biased spring, not shown here. At about the same time the flushing of the toilet bowl 5 is interrupted. The lower chamber 12 'is so large that it is about half filled with air and half with suction 4. When sucking the Absaugmasse 4, the solids are by the sudden Inflow into the chamber 12 'reduced, so that the extracted suction 4' is similar to a suspension. The Fig. 5 shows with the arrow 28, the inflow direction of the suction mass 4 in the lower chamber 12 '. About the Absaugmasse 4 'is an air cushion 21, as mentioned above, about half the volume of the lower chamber 12' occupies.

Ist die Absaugmasse 4 abgesaugt, so wird das Ventil 7 geschlossen und der Kolben 10 fährt nach unten, wobei das Luftpolster 21 komprimiert und ein Überdruck von beispielsweise 2bar erzeugt wird. Nun wird das Ventil 16 geöffnet und infolge des Überdrukkes wird die Absaugmasse 4' in die Druckleitung 17 und schliesslich in die Entsorgungsleitung 18 ausgestossen. Anschliessend wird das Ventil 16 geschlossen. Bei der Bewegung des Kolbens 10 nach unten wird von der Umgebungsluft Frischluft über das Ventil 22 in die obere Kammer 13 eingeleitet. In der Regel ist die Druckleitung 17 wenigstens teilweise mit Absaugmasse 4' gefüllt. Um auch diese Absaugmasse auszustossen, wird vorzugsweise ein zweiter Spülvorgang ausgelöst. Hierbei wird die Toilettenschüssel 5 nochmals gespült und dieses Spülwasser wird mit dem oben erläuterten Vorgang angesaugt und anschliessend ausgestossen. Die Druckleitung 17 wird durch diesen weiteren Vorgang mit Wasser durchgespült und wenigstens teilweise gereinigt. Dieses weitere Spülwasser gelangt in die Entsorgungsleitung 18.If the suction mass 4 is sucked off, the valve 7 is closed and the piston 10 moves downwards, wherein the air cushion 21 is compressed and an overpressure of, for example, 2 bar is generated. Now, the valve 16 is opened and due to Überdrukkes the suction mass 4 'is ejected into the pressure line 17 and finally into the discharge line 18. Subsequently, the valve 16 is closed. During the movement of the piston 10 down fresh air is introduced via the valve 22 into the upper chamber 13 of the ambient air. As a rule, the pressure line 17 is at least partially filled with suction mass 4 '. In order to expel this Absaugmasse, preferably a second flushing process is triggered. Here, the toilet bowl 5 is rinsed again and this rinse water is sucked in with the above-explained process and then ejected. The pressure line 17 is flushed through this further process with water and at least partially cleaned. This additional rinse water enters the disposal line 18th

Die Saugleitung 6 mündet tangential und auch nach unten in die Druckkammer 12. Dies ergibt eine besonders günstige Dynamik der Absaugmasse 4 und damit das Ein- und Ausströmen dieser Masse 4 im Zylinder 8. Die Absaugmasse 4 strömt tangential und nach unten gerichtet in die Druckkammer 12 und spült damit sozusagen den Zylinder 8 und rotiert in der Druckkammer 12. Anschliessend wird die Absaugmasse 4 ausgestossen. Da alles in Bewegung ist, kann ein Absetzen in der Druckkammer 12 vermieden werden. Eventuell doch abgesetzte Teile werden wieder aufgespült. Ein Kontakt mit dem Kolben 10 und der Dichtung wird weitgehend vermieden.The suction line 6 opens tangentially and also down into the pressure chamber 12. This results in a particularly favorable dynamics of the suction mass 4 and thus the inflow and outflow of this mass 4 in the cylinder 8. The suction mass 4 flows tangentially and directed downwards into the pressure chamber 12th and flushes so to speak, the cylinder 8 and rotates in the pressure chamber 12. Subsequently, the suction mass 4 is ejected. Since everything is in motion, settling in the Pressure chamber 12 can be avoided. Eventually deposited parts are rinsed again. Contact with the piston 10 and the seal is largely avoided.

Claims (6)

  1. A toilet system with a toilet pan (5), which can be flushed by a flushing arrangement (1), having a conduit (29) which is connected to the toilet pan and leads to a waste-disposal conduit (18), having means (8) for transporting a suction-extraction substance (4) from the toilet pan (5) into the conduit (29) and into the waste-disposal conduit (18), the means (8) having, in the conduit (29), two valves (7, 16) and, between the latter, a pressure chamber (12) in which it is possible to produce a negative pressure, for the suction extraction of the substance (4) from the toilet pan (5), and a positive pressure, for transporting the substance (4), once extracted by suction, into the waste-disposal conduit (18),it being the case that the pressure chamber (12) is designed as a piston cylinder, wherein the conduit (29) is provided with a suction line (6), which is arranged between the toilet pan (5) and the piston cylinder (8), wherein the piston (10) is connected to a drive (14) in order to produce the positive pressure and negative pressure, characterized in that the piston (10) is driven electromechanically and the the drive (14) is controlled by a control arrangement (26), the two valves (7, 16) mentioned above likewise being controlled by this control arrangement (26), wherein the piston (10) and the two valves (7, 16) are controlled by the control arrangement (26) in such a manner, that said negative pressure in the pressure chamber (12) is produced with closed valves (16, 7) and that in order to extract the substance (4) from the toilet pan (5) the valve (7) is opened comparatively quickly after the negative pressure is reached, so that they are reduced in size by suddenly flowing into the pressure chamber (12), wherein the suction line (6) opens tangentially and downwardly into the pressure chamber (12) and the substance (4) flows tangentially and in a downwardly directed manner into the pressure chamber (12) and rotates in the pressure chamber (12).
  2. The toilet system as claimed in claim 1, characterized in that connected to an outlet (12a) of the pressure chamber (12) is a pressure line (17), through which the substance (4) is transported into the waste-disposal conduit (18).
  3. The toilet system as claimed in one of claims 1 or 2, characterized in that a positive pressure which is greater than 1 bar, preferably greater than 1.5 bar, is produced in the pressure chamber (12).
  4. The toilet system as claimed in one of claims 1 to 3, characterized in that it is possible to adjust the stroke of the piston (10).
  5. The toilet system as claimed in one of claims 1 to 7, characterized in that the pressure chamber (12) forms a unit with the toilet pan (5).
  6. The toilet system as claimed in claim 5, characterized in that, at its lowermost point, the pressure chamber (12) has an outlet (12a) to which a pressure line (17) is connected.
