The collection arrangement has a first suction and ventilation valves and is connected by a negative pressure line to a collection receptacle and joined to a negative pressure source. The waste water can also be transported to the negative pressure line by opening a second suction valve assigned to the sanitary device. The waste water from the sanitary device is collected in a first casing (112) or a first intermediate container. Either the first casing has a base part (116) to generate a standing pressure with a first valve connected to a standing pressure membrane, a second valve connected to a control membrane and a third valve connected to a switching membrane for connecting the membrane to a negative pressure line, or the first casing is divided into two chambers (122,124) by a membrane (118), with the first chamber having an inlet for the waste water and an opening (142) for the suction pipe (134), which is opened or closed by the membrane moving under the forces of springs (150-154). The first intermediate container is connected to a control arrangement, which is connected to a first line through a third check valve connected to a negative pressure line and to a second line through a second ventilation valve connected to atmospheric pressure. The second ventilat ion valve is connected to a third line through the third check valve, to prevent flow if there is an over pressure. A second suction valve in a second casing is operated by a fourth valve, which is adjusted by a fourth membrane that divides the second casing into a third chamber, which is connected to negative pressure, and a fourth chamber, which is connected to atmospheric pressure. A spring element acts on the fourth membrane towards the fourth chamber, to move the fourth membrane and operate the fourth valve. The waste water is drawn directly into the collection receptacle or a second intermediate container through a second suction valve. A sensor element is arranged in the second intermediate chamber, which controls a fourth suction valve and a connection to the atmosphere, according to the amount of waste water collected in the second intermediate chamber.

Die Erfindung bezieht sich auf eine Toilettenschüssel, insbesondere bestimmt für eine Vakuum-Toilettenanlage, mit im oberen Rand der Toilettenschüssel angeordneter Spüldüse zum Abgeben von die Toilettenschüssel innenflächig besprühender bzw. bespülender Flüssigkeit, wobei die Spüldüse einen scheibenförmigen sich entlang der Toilettenschüsselinnenfläche erstreckenden ersten Abschnitt mit einem Austrittsschlitz bogenförmigen Verlaufs sowie einen in einer Aufnahme der Toilettenschüssel sich erstreckenden bzw. fixierten einen Kanal aufweisenden zweiten Abschnitt umfasst, über den die Flüssigkeit zu dem Austrittsschlitz strömt.The invention relates to a toilet bowl, in particular intended for a vacuum toilet installation, arranged in the upper edge of the toilet bowl flushing nozzle for Dispensing from the toilet bowl inside spraying liquid, the rinsing nozzle being a disc-shaped one along the toilet bowl inner surface extending first portion with an exit slot arcuate course and a in a recording of the toilet bowl extending or fixed a channel comprising the second section, via which the liquid to the outlet slot flows.

Dem DE-U-297 00 985 ist eine Vakuum-Toilette zu entnehmen. Dabei geht vom unteren Schüsselbereich eine Rohrleitung aus, die außerhalb der Schüssel in einer bestimmten Höhe unterhalb der Spüldüsen offen endet. Hierdurch wird ein Überlauf gebildet, der sicherstellt, dass dann, wenn die Toilettenschüssel durch eine Betriebsstörung volllaufen sollte, der Wasserspiegel nicht bis an die Düsen gelangen kann, wodurch diese in unzulässiger Weise Abwasser in die Trinkwasserleitung saugen könnten. Nachteil der bekannten Ausbildung ist es, dass dann, wenn die Absaugöffnung der Toilettenschüssel mit Papier und Feststoffen belegt sein sollte, die Schüssel nicht ordnungsgemäß entleert werden kann, da über die außerhalb der Toilettenschüssel verlaufende Leitung Falschluft angesaugt würde, so dass infolgedessen in der Toilettenschüssel nicht der erforderliche Unterdruck aufgebaut werden kann, um die Schüssel vollständig leer zu saugen. DE-U-297 00 985 discloses a vacuum toilet. It goes from the bottom Bowl area a pipeline out, outside the bowl at a certain height ends open below the flushing nozzles. This creates an overflow that ensures that if the toilet bowl was to run through a malfunction, the water level can not get to the nozzles, causing them in an inadmissible way wastewater could suck into the drinking water line. Disadvantage of the known training is that if the suction opening of the toilet bowl is filled with paper and solids The bowl can not be properly emptied because of the outside of the bowl Toilet bowl running line false air would be sucked, so that as a result the toilet bowl can not be built up the required vacuum to the Bowl completely empty to suck.

Im oberen Randbereich sind des Weiteren eine Vielzahl von Düsen angeordnet, um die Toiletteninnenschüssel auszuspülen. Dabei ist der Nachteil gegeben, dass ein Teil des Mittenbereichs zwischen zwei aufeinanderfolgenden Düsen selbst nicht bespült werden kann.In the upper edge region, a plurality of nozzles are further arranged to the Rinse toilet bowl. The disadvantage is that part of the middle range itself can not be rinsed between two successive nozzles.

Aus der DE-A-25 29 169 ist eine Vorrichtung zur Verteilung von Spülwasser in einer Klosettschüssel bekannt, die aus einem im oberen Klosettschüsselrand verlaufenden gegen die Innenwand der Klosettschüssel gerichteten Längskanal aufweist.

Der vorliegenden Erfindung liegt das Problem zugrunde, eine Toilettenschüssel der eingangs genannten Art, insbesondere bestimmt für eine Vakuum-Toilettenanlage, so weiterzubilden, dass mit wenigen Düsen sichergestellt ist, dass die Toilettenschüssel umfassend gesäubert werden kann, so dass folglich nur geringe Flächen verbleiben, die nicht überspült werden können.The present invention is based on the problem, a toilet bowl of the beginning mentioned type, in particular intended for a vacuum toilet system, so educate that with a few nozzles ensures that the toilet bowl can be cleaned thoroughly, so that consequently only small areas remain, the can not be washed over.

Erfindungsgemäß wird das Problem im Wesentlichen dadurch gelöst, dass der Austrittsschlitz der Spüldüse in seinem jeweiligen Endbereich in eine Bohrung übergeht, deren Durchmesser D größer als der Austrittsschlitz in seiner Breite S ist, dass die Bohrungen einen Winkel α mit 140° ≤ α ≤ 180° einschließen und dass die von dem Austrittsschlitz aufgespannte erste Ebene in Richtung der Innenfläche der Toilettenschüssel geneigt verläuft.According to the invention, the problem is essentially solved by the Exit slot of the flushing nozzle in its respective end region merges into a bore, whose diameter D is greater than the exit slot in its width S is that the holes include an angle α with 140 ° ≤ α ≤ 180 ° and that of the exit slot spanned first level inclined towards the inner surface of the toilet bowl.

Die die Randbegrenzungen des bogenförmig verlaufenden Austrittsschlitzes bildenden Bohrungen schließen insbesondere einen Winkel α mit 160° ≤ α ≤ 165°. Durch diese Erstreckung ist sichergestellt, dass einerseits ein Überspritzen von Spülwasser über den Rand der Toilettenschüssel unterbunden wird und andererseits die Toilettenschüsselinnenfläche fast vollständig benetzt wird.The forming the marginal boundaries of the arcuate exit slot Holes in particular include an angle α with 160 ° ≤ α ≤ 165 °. Through this Extension is ensured that on the one hand overspray of rinse water over the Edge of the toilet bowl is prevented and on the other hand, the toilet bowl inner surface is almost completely wetted.

Der Durchmesser D der Bohrung und die Breite S des Austrittsschlitzes betragen vorzugsweise 1,5 S < D < 2,5 S, vorzugsweise D in etwa 1,8 S.The diameter D of the bore and the width S of the exit slot are preferably 1.5 S <D <2.5 S, preferably D in about 1.8 s.

Des Weiteren sollten die Bohrungen den den zweiten Abschnitt durchsetzenden Kanal außermittig schneiden, wobei insbesondere vorgesehen ist, dass die Bohrungen den Kanal in dessen schlitztabgewandtem Randbereich schneiden.Furthermore, the holes should off-center the channel passing the second section in particular, it is provided that the holes in the channel in cut its slot facing away edge area.

Der erste Abschnitt der Düse spannt mit seiner Innenfläche eine erste Ebene und der von dem Kanal ausgehende Austrittsschlitz ein zweite Ebene auf, wobei die erste und die zweite Ebene zueinander geneigt verlaufen. Insbesondere ist vorgesehen, dass die von dem Austrittsschlitz aufgespannte Ebene in Richtung der Innenfläche der Toilettenschüssel geneigt verläuft. Vorzugsweise beschreiben die erste und die zweite Ebene einen Winkel β mit 4° < β < 8°, vorzugsweise 6° < β < 6,5°. The first section of the nozzle biases with its inner surface a first plane and that of outgoing channel to a second level, wherein the first and the second Level inclined to each other. In particular, it is provided that the of the Outlet slot spanned plane inclined towards the inner surface of the toilet bowl runs. Preferably, the first and second planes define an angle β with 4 ° <β <8 °, preferably 6 ° <β <6.5 °.

Hierdurch erfolgt eine Art Selbstreinigung. Ferner sind die zu den seitlichen Taschen 30, 32 führenden Öffnungen der Aussparung 30 querschnittsmäßig derart ausgebildet, dass eine Reinigung des Kanals bzw. der Kammer, d. h. des Überlaufs 28 von Hand erfolgen kann. Die im Ausführungsbeispiel zu den Befestigungstaschen 32, 34 führenden Auslässe erstrecken sich dabei oberhalb des rinnenförmig ausgebildeten Bodens 40.The channel-shaped portion 30 of the toilet bowl has one of the Opening 36 outgoing rising channel-shaped bottom 40, thereby ensuring is that when unintentionally liquid flows into the section 30, this in the Area 18 of the toilet bowl 10 can flow back. This results in a kind of self-cleaning. Furthermore, the leading to the side pockets 30, 32 openings of the Recess 30 cross-sectionally designed such that a cleaning of the channel or the chamber, d. H. the overflow 28 can be done by hand. The in the embodiment too The attachment pockets 32, 34 leading outlets extend above the gutter-shaped bottom 40.

Oberhalb der Öffnung 36 des Überlaufs 28 ist die Toilettenwandung 42 im Vergleich zu dem unterhalb der Öffnung 36 verlaufenden Bereich 44 vorspringend ausgebildet, wie insbesondere die Ansicht A in Fig. 3 verdeutlicht.Above the opening 36 of the overflow 28 is the toilet wall 42 in comparison to the formed below the opening 36 extending portion 44 projecting, such as in particular the view A in Fig. 3 illustrates.

Wie sich insbesondere aus den Fig. 6, 8 ergibt, ist durch die Geometrie und Höhenanordnung des Überlaufs 28 sichergestellt, dass dann, wenn die Toilettenschüssel 10 unzulässig mit Flüssigkeit gefüllt sein sollte, diese gezielt aus der Toilettenschüssel über den Überlauf 28 zu den Befestigungstaschen 32, 34 zum Bodenbereich des Sanitärraums geführt wird, in dem die Toilettenschüssel 10 angeordnet ist. Somit ist sichergestellt, dass die Düsen 22, 23 nicht mit dem Abwasser in Berührung kommen können.As is apparent in particular from FIGS. 6, 8, is by the geometry and height arrangement of the overflow 28 ensures that when the toilet bowl 10 inadmissible with Liquid should be filled, this targeted from the toilet bowl over the overflow 28 too the attachment pockets 32, 34 is guided to the bottom portion of the sanitary room in which the Toilet bowl 10 is arranged. Thus, it is ensured that the nozzles 22, 23 not with can come into contact with the wastewater.

Durch die Zwangsführung des überlaufenden Wassers in den Sanitärraum hinein kann keine Flüssigkeit hinter eine Vorwandinstallation oder in einen Hohlraum der Toilettenschüssel 10 bzw. deren Körpers gelangen, so dass nach erfolgtem Überlauf und Säuberung des Sanitärraums eine Geruchsbelästigung ausgeschlossen ist.Due to the forced operation of the overflowing water into the sanitary room can not Liquid behind a wall installation or in a cavity of the toilet bowl 10 or their body, so that after overflow and purge the Sanitary room odor nuisance is excluded.

Wie insbesondere aus der Ansicht A in Fig. 3 erkennbar ist, sind im oberen Randbereich des Toilettenkörpers 11 allein zwei Düsen 22, 23 vorgesehen, um über diese Reinigungsflüssigkeit zum Säubern der Innenfläche 24 der Toilettenschüssel 10, d.h. deren Körpers 11 zu versprühen. Dabei sind die Düsen 22, 23 diametral gegenüber und etwa mittig jeweils in jeder Längsseite angeordnet. As can be seen in particular from the view A in Fig. 3, are in the upper edge region of the Toilet body 11 alone two nozzles 22, 23 provided to over this Cleaning fluid for cleaning the inner surface 24 of the toilet bowl 10, i. their To spray body 11. The nozzles 22, 23 are diametrically opposite and approximately in the middle arranged in each longitudinal side.

Ungeachtet dessen ist jedoch sichergestellt, dass die Innenfläche 24 nahezu vollständig besprüht und damit gereinigt werden kann. Hierzu sind folgende Maßnahmen vorgesehen. Jede Düse 22, 23 besteht aus einem pilzförmigen Körper, der sich aus einem sich entlang der Innenfläche 24 im oberen Rand 20 der Toilettenschüssel 10 erstreckenden ersten Abschnitt 44 und einem zweiten sich in den Körper 11 hinein erstreckenden Abschnitt 46 zusammensetzt. Der zweite Abschnitt 46 wird von einem zentralen Kanal 48 durchsetzt, über den Spülflüssigkeit zuleitbar ist. Von dem Kanal 48 geht ein einen bogenförmigen Verlauf aufweisenden Schlitz 50 aus, der im Umfangsrand 52 des ersten Abschnitts 44 mündet. Dabei erstreckt sich der Austrittsschlitz 50 über einen Bogen, der vorzugsweise im Bereich von 160° bis 165° liegt und dem Bodenbereich der Schüssel 10 zugewandt ist. Die Erstreckung erfolgt dabei symmetrisch zur Vertikalachse 54, die senkrecht oder in etwa senkrecht zu einer Ebene verläuft, die von den Düsen 22, 23 aufgespannt wird und parallel zum oberen Rand 20 der Toilettenschüssel 10 verläuft.Regardless, however, it is ensured that the inner surface 24 is almost complete sprayed and can be cleaned with it. For this purpose, the following measures are provided. Each nozzle 22, 23 consists of a mushroom-shaped body, which extends from one along the Inner surface 24 in the upper edge 20 of the toilet bowl 10 extending first portion 44th and a second portion 46 extending into the body 11. The second section 46 is penetrated by a central channel 48, via the Rinsing fluid is zuleitbar. From the channel 48 is an arcuate course comprising slot 50, which opens in the peripheral edge 52 of the first portion 44. there the exit slot 50 extends over an arc, preferably in the range of 160 ° is up to 165 ° and the bottom portion of the bowl 10 faces. The extension takes place while symmetrical to the vertical axis 54, which is perpendicular or approximately perpendicular to a plane runs, which is spanned by the nozzles 22, 23 and parallel to the upper edge 20 of the Toilet bowl 10 runs.

Der Schlitz 50 geht in seinem jeweiligen Ende in eine Bohrung 56, 58 über, deren Durchmesser D größer als der Schlitz 50 in seiner Breite S ist. Dabei beträgt der Durchmesser in etwa das 1,8fache des Breite S des Schlitzes 50.The slot 50 passes in its respective end into a bore 56, 58, whose Diameter D is greater than the slot 50 in its width S is. The diameter is thereby about 1.8 times the width S of the slot 50.

Die Bohrungen 56, 58 gehen - wie der Austrittsschlitz 50 - von dem Kanal 48 aus, über den die Reinigungsflüssigkeit den Düsen 22, 23 zugeführt wird.The bores 56, 58 are - as the exit slot 50 - from the channel 48, over the the cleaning liquid is supplied to the nozzles 22, 23.

Da die Bohrungen 56, 58 den Austrittsschlitz 52 in seiner jeweiligen radialen Begrenzung durchsetzen, schließen die Bohrungen 56, 58 einen Winkel α von in etwa 160 bis 165° ein.Since the holes 56, 58 the exit slot 52 in its respective radial boundary enforce, include the holes 56, 58 an angle α of about 160 to 165 °.

Der Schlitz 50 spannt eine Ebene auf, die geneigt zur Außen- bzw. Innenfläche 60, 62 des ersten Abschnitts 44 der Düse 22, 23 verläuft. Dabei wird ein Winkel β von in etwa 6° bis 7° eingeschlossen, wodurch sich der Schlitz 50 bei eingebauter Düse 22, 23 in Richtung der Innenfläche 24 der Toilettenschüssel 10 erstreckt.The slot 50 biases a plane inclined to the outer or inner surface 60, 62 of the first portion 44 of the nozzle 22, 23 extends. In this case, an angle β of about 6 ° to 7 ° enclosed, whereby the slot 50 with built-in nozzle 22, 23 in the direction of Inner surface 24 of the toilet bowl 10 extends.

Die Bohrungen 56, 58 werden vorzugsweise durch Bohren ausgebildet, wobei der Schlitz 50 bis zu den Querbohrungen 56, 58 gefräst wird. The bores 56, 58 are preferably formed by drilling, wherein the slot 50 is milled to the transverse bores 56, 58.

Dadurch, dass der Schlitz 50 zu der Fläche 60 geneigt verläuft, tritt ersterer sehr nah an der inneren Begrenzungsfläche 60 aus, die ihrerseits zumindest abschnittsweise flächig an der Innenfläche 24 der Toilettenschüssel 10 anliegt. Hierdurch und durch die Bohrungen 56, 58 ergibt sich ein gutes Spülverhalten, das sicherstellt, dass die Toilettenschüssel 10 bzw. deren Innenfläche 24 im gewünschten Umfang gereinigt wird, also auch im erforderlichen Umfang am Randbereich zwischen den Düsen 22, 23.The fact that the slot 50 is inclined to the surface 60, the former occurs very close to the inner boundary surface 60, which in turn at least partially planar at the Inner surface 24 of the toilet bowl 10 is applied. In this way and through the bores 56, 58 results in a good flushing, which ensures that the toilet bowl 10 and their Inner surface 24 is cleaned to the desired extent, including the required extent at the edge region between the nozzles 22, 23.

Aus der Darstellung nach Fig. 10 wird des Weiteren ersichtlich, dass die Bohrungen 56, 58 nicht mittig von dem Kanal 48 ausgehen, sondern in etwa von dessen dem Schlitz 50 fernliegenden Randbereich 64.From the illustration of FIG. 10 is further apparent that the bores 56, 58 do not emanate centrally from the channel 48, but approximately from the slot 50th remote edge region 64.
