Description
Die Erfindung betrifft einen Spülkasten für eine Toilettenspülung mit einem Wasserabfluß zu einem Toilettenbecken, der von einem Spülventil gesteuert ist, das durch einen über ihm in einem Gehäuse stehenden Wasservorrat mit einer als Rohr ausgebildeten Verlängerung hindurchragt, durch dessen Innenraum Abluft aus dem Toilettenbecken von einem Unterdruckerzeuger über ein sich durch den Wasservorrat erstreckendes, mit dem Unterdruckerzeuger verbundenes Absaugrohr abgesaugt wird, das zu mindestens einem die aus dem Toilettenbecken abgesaugte Abluft aufnehmenden Ablüfter führt.The invention relates to a cistern for flushing toilets with a water drain to a toilet bowl by a Flush valve is controlled by one above it in a housing standing water supply with an extension designed as a pipe protrudes through the interior of which is exhaust air from the toilet bowl from a vacuum generator to one through the Water supply extending, connected to the vacuum generator Suction pipe is sucked off, which to at least one from the Exhaust air-absorbing ventilator leads to toilet bowls.
Ein solcher Spülkasten ist aus der US-A-1 381 710 bekannt geworden. Er ist mit einem Absaugrohr versehen, das eine Verlängerung des Spülventils dient. An dem aus dem Spülwasservorrat herausragenden oberen Ende der Verlängerung ist ein Ventilator vorgesehen, der Abluft aus einem Toilettenbecken absaugt und in eine Abluftleitung hineindrückt. Zwischen der Abluftleitung und dem Absaugrohr ist kein Geruchverschluß vorgesehen, so daß diese beiden Rohre ständig in offener Verbindung miteinander stehen. Auf diese Weise besteht die Gefahr, daß die mit üblen Gerüchen belastete Abluft, die sich beispielsweise in einem Abwassersystem befindet, ständig durch das Absaugerohr in das Toilettenbecken und von diesem in ein das Toilettenbecken umgebenden Toilettenraum eindringt. Die sich auf diese Weise im Toilettenraum ausbreitende übel riechende Abluft macht das System für die Verwendung in Toilettenräumen weitgehend ungeeignet.Such a cistern is known from US-A-1 381 710. It is equipped with an exhaust pipe, which is an extension the purge valve. On the protruding from the rinse water supply a fan is provided at the top end of the extension, sucks the exhaust air from a toilet bowl and into an exhaust air duct pushes in. Between the exhaust pipe and the suction pipe no odor trap is provided, so that these two Pipes are always in open communication with each other. To this There is a risk that the exhaust air contaminated with bad smells, which is, for example, in a sewage system, constantly through the suction pipe into and from the toilet bowl penetrates into a toilet room surrounding the toilet bowl. The bad smelling that spreads in the toilet room in this way Exhaust air makes the system suitable for use in toilet rooms largely unsuitable.
Aufgabe der vorliegenden Erfindung ist es daher, den Spülkasten der einleitend genannten Art so zu verbessern, daß er bei einer einfachen Installation und vergleichsweise geringen Abmaßen eine optimale Kombination von Spülfunktion einerseits und Absaugfunktion andererseits zuläßt, ohne daß übel riechende Abluft in den Toilettenraum eindringen kann.The object of the present invention is therefore the cistern to improve the type mentioned in the introduction so that it at a simple installation and comparatively small dimensions optimal combination of flushing function on the one hand and suction function on the other hand allows without smelly exhaust air in the Toilet room can penetrate.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Verlängerung und das Absaugrohr als voneinander getrennte Rohre ausgebildet sind und die Rohre eine über eine Sperrwassermenge steuerbare Verbindung an einem aus dem Wasservorrat herausragenden oberen Ende der Verlängerung aufweisen und mit dem Spülventil eine Ablaufgarnitur bilden, die in einer aus dem Gehäuse herausführenden Öffnung befestigt ist, und die Sperrwassermenge in einem aus dem Wasservorrat herausragenden Sperrwasserbehälter im getrennten Zustand der Verbindung angesammelt und zur Freigabe der Verbindung reduziert ist.This object is achieved in that the extension and the suction pipe is designed as separate pipes and the pipes are controllable via a quantity of sealing water Connection to an upper one protruding from the water supply Have end of the extension and with the flush valve Form waste set, which in a leading out of the housing Opening is fixed, and the amount of sealing water in one out the water reservoir projecting in the separate State of the connection accumulated and to release the connection is reduced.
Dieser Spülkasten läßt die Vereinigung der beiden Funktionen der Toilettenspülung einerseits und der Abluftabsaugung andererseits in optimaler Weise zu. Er besitzt lediglich zwei sich durch den Spülwasservorrat hindurchstreckende Rohre, von denen das eine gleichzeitig zur Betätigung des Spülventils und zur Absaugung der Abluft dient, während das andere die Verbindung zum Ablüfter herstellt. Dieser Ablüfter kann je nach örtlicher Gegebenheit der Installation entweder als ein die Abluft aufnehmender Filter oder als ein Abluftsystem ausgebildet sein, in das die abgesaugte Abluft abgeführt wird.This cistern allows the union of the two functions of Toilet flushing on the one hand and exhaust air extraction on the other in an optimal way. He only owns two through the Pipes extending through the rinse water, one of which at the same time to actuate the flushing valve and to extract the Exhaust air serves while the other connects to the exhaust fan. This ventilator can be used depending on the local conditions of the installation either as an exhaust air filter or be designed as an exhaust air system into which the extracted exhaust air is dissipated.
Mit diesem Abluftsystem können beispielsweise mehrere Toilettenbecken verbunden sein, deren Abluft durch das Abluftsystem entsorgt wird. Es ist jedoch auch möglich, als Abluftsystem ein Abwassersystem zu wählen, durch das eine allgemeine Abwasserentsorgung vorgenommen wird.With this exhaust air system, for example, several toilet bowls be connected, the exhaust air disposed of through the exhaust system becomes. However, it is also possible to use a sewage system as an exhaust air system to choose through which a general sanitation is made.
Das Absaugrohr einerseits und die Verlängerung andererseits können durch eine Glocke miteinander verbunden sein, die sowohl die Verlängerung als auch das in ihr geführte Absaugrohr umgibt. Diese Glocke taucht vorteilhafterweise mit ihrem unteren Rand in eine ihren Innenraum gasdicht abschließende Sperrwassermenge ein, so daß durch die Verlängerung herangeführte Abluft in das Absaugrohr abgesaugt werden kann, ohne daß aus der Glocke Abluft herausdringen kann.The suction pipe on the one hand and the extension on the other hand can be connected by a bell, which is both the extension as well as the suction pipe that runs inside it. This Bell advantageously dips into one with its lower edge their interior gas-tight sealing water volume, so that exhaust air brought in by the extension into the suction pipe can be suctioned off without exhaust air escaping from the bell can.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung ist der Sperrwasserbehälter mit einem Spülwasserzulauf verbunden, über den Spülwasser in das Gehäuse eingespeist wird. Auf diese Weise wird eine im Sperrwasserbehälter stehende Sperrwassermenge Spülzwecken nutzbar gemacht, wenn die Sperrwassermenge aus dem Sperrwasserbehälter verdrängt wird. Der am oberen Ende der Verlängerung ausgebildete Sperrwasserbehälter besitzt den großen Vorteil, daß er einerseits klein hergestellt und konstruktiv auf einfache Weise im Spülkasten gehaltert werden kann. Er beansprucht wenig Platz innerhalb des Gehäuses. According to a further preferred embodiment of the invention the sealing water tank connected to a rinse water inlet via the rinse water is fed into the housing. In this way is a quantity of sealing water in the sealing water tank for rinsing purposes made usable when the amount of sealing water from the sealing water tank is ousted. The one at the top of the extension trained sealing water tank has the great advantage that on the one hand, it is small and constructive in a simple manner can be kept in the cistern. It takes up little space inside the case.

Darüber hinaus können in einem zwischen dem Absaugrohr (29) und der Verlängerung (30) ausgebildeten Spalt (50) Kulissen (51) angeordnet sein, die einen vom Spalt (50) gebildeten Querschnitt verengen. Derartige Kulissen (51) können entweder auf dem Absaugrohr (29) oder der Verlängerung (30) über die gesamte Länge des Spaltes (50) verteilt sein, um zu verhindern, daß nach dem Öffnen des Spülventils (49) Spülwasser (48) im Spalt (50) hochspritzt.The suction pipe (29) is approximately perpendicular to the housing (1) extending main part (39) via a plug connection (40) connected to the connector (31). The main part (39) has a much larger diameter than the connector (31). In an interior (41) enclosed by the main part (39) a vacuum generator (42) with its drive (43) on a console (44) stored. The main part (39) extends with a sloping bottom (45) towards the plug connection (40), the opens off-center into the main part (39). The suction pipe (29) dominates the sloping floor (45) with an apron (46) between the and the sloping bottom (45) a pocket (47) is formed. This pocket (47) represents a receptacle for rinsing water (48), that after opening a flush valve formed on the nut (20) (49) sprayed on the suction pipe (29). In addition, you can in a between the suction pipe (29) and the extension (30) trained gap (50) scenes (51) can be arranged, the one narrow the cross section formed by the gap (50). Such scenes (51) can either on the suction tube (29) or the extension (30) over the entire length of the gap (50) to be distributed prevent flushing water after opening the flush valve (49) (48) splashed up in the gap (50).
Das Spülventil (49) besitzt einen Ventilsitz (52), der auf der Mutter (20) ausgebildet ist. Dieser Ventilsitz (52) wird von einem in lotrechter Richtung beweglichen Ventilteil (53) beaufschlagt, der im geschlossenen Zustand des Spülventils (49) auf dem Ventilsitz (52) mit einer Dichtung (54) aufliegt. Diese Dichtung (54) ist in einem Dichtungssitz (55) geführt, der innerhalb des Ventilteils (53) verläuft. Die Dichtung (54) liegt mit einem aus dem Dichtungssitz (55) herausragenden Außenteil (56) auf dem Ventilsitz (52) auf, und zwar an jener Stelle, an der der Außenteil (56) aus dem Dichtungssitz (55) herausragt. Dabei kann der Ventilteil (53) mit einem sich unterhalb des Dichtungssitzes (55) erstreckenden Unterteil (57) in einen vom Ventilsitz (52) umschlossenen Innenraum hineinragen. Der Unterteil (57) besitzt eine konische Außenfläche (58), deren Steigung einer entsprechenden konischen Innenfläche (59) entspricht, mit der sich der Ventilsitz (52) auf der Mutter (20) erhebt. Bei nachlassender Elastizität der Dichtung (54) liegen die beiden konischen Flächen (58, 59) aufeinander, so daß eine Verformung der Dichtung (54) sich in den Grenzen hält, der vom Abstand der beiden konischen Flächen (58, 59) voneinander vorgegeben ist. Außerdem wird durch diese Ausbildung des Spülventils (49) dafür gesorgt, daß sich die Gesamtlänge der Ablaufgarnitur (3) nur in geringen Grenzen ändert.The flush valve (49) has a valve seat (52) on the Nut (20) is formed. This valve seat (52) is one acted upon in the vertical direction movable valve part (53), the one in the closed state of the flush valve (49) on the valve seat (52) rests with a seal (54). This seal (54) is guided in a sealing seat (55) which is inside the valve part (53) runs. The seal (54) lies with one of the Seal seat (55) protruding outer part (56) on the valve seat (52) at the point where the outer part (56) protrudes from the seal seat (55). The valve part (53) with one extending below the sealing seat (55) Lower part (57) into an interior enclosed by the valve seat (52) protrude into it. The lower part (57) has a conical one Outer surface (58), the slope of a corresponding conical Corresponds to the inner surface (59) with which the valve seat (52) the mother (20). If the seal becomes less elastic (54) the two conical surfaces (58, 59) lie on top of each other, see above that a deformation of the seal (54) is limited the distance between the two conical surfaces (58, 59) from each other is specified. In addition, this design of the flush valve (49) ensured that the total length of the drain fitting (3) changes only to a limited extent.
Das Ventilteil (53) ist mit einer Steckverbindung (60) an einem ihm zugewandten Ende (61) der Verlängerung (30) befestigt. Durch Anheben der Verlängerung (30) wird das Ventilteil (53) vom Ventilsitz (52) abgehoben, so daß das Spülventil (49) geöffnet ist und das Spülwasser (48) aus dem Innenraum (2) durch das geöffnete Spülventil (49) in die Absaugleitung (26) abfließen kann. Dabei wird die Verlängerung (30) bezüglich des Absaugrohres (29) bewegt.The valve part (53) is connected to a plug connection (60) attached to him end (61) of the extension (30). By Lifting the extension (30) the valve part (53) from the valve seat (52) lifted off so that the flushing valve (49) is open and the flushing water (48) from the interior (2) through the open Flush valve (49) can flow into the suction line (26). Here the extension (30) is moved with respect to the suction pipe (29).
Zu diesem Zwecke ist die Verlängerung (30) mit einem Spülknopf (62) verbunden, der aus dem Deckel (9) des Gehäuses (1) herausragt. Mit diesem Spülknopf (62) ist eine Glocke (63) fest verbunden, die einen Innenraum (64) umschließt, der eine Verbindung zwischen dem Spalt (50) und dem Innenraum (41) des Absaugrohres (29) herstellt. Dieser Innenraum (64) wird von einem weitgehend zylindrischen Mantelteil (65) und einem Glockenboden (66) begrenzt, der bei geschlossenem Spülventil (49) mit dem Deckel (9) etwa in einer Ebene verläuft. In diesen Innenraum (64) ragt das Absaugrohr (29) mit einer Verjüngung (67) hinein, die sich in Richtung auf den Hauptteil (39) des Absaugrohres (29) durch eine kegelstumpfförmige Erweiterung (68) erweitert. In der Verjüngung (67) ist die Glocke (63) mit einer zylindrischen Einheit (69) geführt, die sich durch das Zentrum des Innenraumes (64) etwa parallel zum Mantelteil (65) erstreckt. Diese zylindrische Einheit (69) besteht aus mindestens zwei von einer Mittelachse (70) ausgehenden Flügeln (71, 72), die mit ihren der Mittelachse abgewandten äußeren Kanten (73, 74) in der Verjüngung (67) geführt sind. An der Mittelachse (70) ist der Spülkopf (62) befestigt. For this purpose, the extension (30) with a flush button (62) connected, which protrudes from the cover (9) of the housing (1). A bell (63) is firmly connected to this flush button (62), which encloses an interior (64) that connects between the gap (50) and the interior (41) of the suction pipe (29) manufactures. This interior (64) is largely cylindrical Cladding part (65) and a bell bottom (66) limits the with the flushing valve (49) closed with the cover (9) approximately in one Level runs. The suction pipe (29) protrudes into this interior space (64) with a taper (67) that extends towards the Main part (39) of the suction pipe (29) by a truncated cone Extension (68) extended. The bell is in the taper (67) (63) with a cylindrical unit (69), which runs through the center of the interior (64) approximately parallel to the casing part (65) extends. This cylindrical unit (69) consists of at least two wings (71, 72) extending from a central axis (70), the with their outer edges (73, 74) facing away from the central axis in the taper (67) are guided. On the central axis (70) is the Rinsing head (62) attached.
Die Verjüngung (67) endet in einem Abstand (75) vom Glockenboden (66), der groß genug ist, um die Glocke (63) in Richtung auf den Innenraum (2) absenken zu können. Über diesen Abstand (75) wird durch den Spalt (50) aufsteigende Abluft in den Innenraum (41) des Absaugrohres (29) gesaugt. An einem in den Innenraum (64) der Glocke (63) hineinragenden oberen Ende (76) der Verjüngung (67) ist eine Umbörtelung (77) befestigt, die in einem Winkel von etwa 180° etwa planparallel zu einer ihr zugewandten Außenfläche (78) der Verjüngung (67) verläuft. Die Umbörtelung (77) ist mit dem oberen Ende (76) über ein ringförmiges Verbindungsstück (79) verbunden, das mit einer Steckverbindung (80) am oberen Ende (76) befestigt ist. Dieses Verbindungsstück (79) ist in Form eines abgestumpften Kegels leicht in Richtung auf die Umbörtelung (77) geneigt, so daß gegebenenfalls in Richtung auf das obere Ende (76) vordringende Wassertropfen über das Verbindungsstück (79) in Richtung auf die Umbörtelung (77) ablaufen können, ohne daß sie in den Innenraum (41) eindringen.The taper (67) ends at a distance (75) from the bell bottom (66), which is large enough to move the bell (63) towards the To be able to lower the interior (2). About this distance (75) through the gap (50) rising air into the interior (41) of the Suction tube (29) sucked. On one in the interior (64) of the Bell (63) protruding upper end (76) of the taper (67) an edging (77) is attached, which is at an angle of about 180 ° approximately plane-parallel to an outer surface facing it (78) the taper (67). The edging (77) is with the upper end (76) connected via an annular connecting piece (79), attached with a connector (80) at the upper end (76) is. This connecting piece (79) is in the form of a truncated Cone slightly inclined towards the edging (77), so that, if necessary, in the direction of the upper end (76) advancing water drops over the connecting piece (79) in the direction can run on the edging (77) without them in the Penetrate interior (41).
Zwischen der Verjüngung (67) und er Umbörtelung (77) ist ein etwa zylindrischer Ringraum (81) ausgebildet, in den ein Sperrwasserbehälter (82) mit einer ringförmigen Innenwandung (83) hineinragt. Dieser Sperrwasserbehälter (82) ist fest auf ein dem Spülventil (49) abgewandtes oberes Ende (84) der Verlängerung (30) aufgesetzt. Zu diesem Zwecke ragt aus einem dem oberen Ende (84) zugewandten Boden (85) des Sperrwasserbehälters (82) eine ringförmige Vertiefung (86) hervor, an deren Außenwandung die Verlängerung (30) mit einer Steckverbindung (87) befestigt ist.Between the taper (67) and the edging (77) there is an approx cylindrical annular space (81) into which a sealing water tank (82) protrudes with an annular inner wall (83). This sealing water tank (82) is firmly on the flush valve (49) facing away from the upper end (84) of the extension (30). For this purpose protrudes from an upper end (84) Bottom (85) of the sealing water tank (82) an annular Indentation (86), on the outer wall of the extension (30) is fastened with a plug connection (87).
Etwa konzentrisch zur ringförmigen Innenwandung (83) verläuft eine ringförmige Außenwandung (88) des Sperrwasserbehälters, die fest mit dem Boden (85) verbunden ist. Auf diese Weise bildet der Sperrwasserbehälter (82) einen von der Innenwandung (83), dem Boden (85) und der Außenwandung (88) begrenzten Behälterraum (89) aus, in den die Glocke (63) mit ihrem Mantelteil (65) hineinragt. Dabei ist der Durchmesser des Mantelteils (65) so gemessen, daß die Umbörtelung (77) innerhalb des Innenraumes (64) der Glocke (63) verläuft und zwischen der Umbörtelung (77) und dem Mantelteil (65) der Glocke (63) ein ringförmiger Spaltraum (90) verbleibt, dessen Querschnitt groß genug ist, um einen vom Unterdruckerzeuger (42) erzeugten Abluftstrom (91) aus dem Ringraum (81) in Richtung auf den Innenraum (41) des Absaugrohres (29) absaugen zu können.One runs approximately concentrically to the annular inner wall (83) annular outer wall (88) of the sealing water tank, which is fixed is connected to the floor (85). In this way, the Sealing water tank (82) one from the inner wall (83), the bottom (85) and the outer wall (88) limited container space (89) into which the bell (63) with its jacket part (65) protrudes. The diameter of the jacket part (65) is measured so that the edging (77) inside the interior (64) of the bell (63) runs and between the edging (77) and the jacket part (65) the bell (63) has an annular gap space (90), the cross section of which is large enough to be from the vacuum generator (42) generated exhaust air flow (91) from the annular space (81) in the direction to be able to suction on the interior (41) of the suction pipe (29).
Dieser Abluftstrom (91) wird aus dem Spalt (50) durch einen Ringraum (92) angesaugt, der von der ringförmigen Innenwandung (83) einerseits und der Außenfläche (78) der Verjüngung (67) andererseits gebildet wird. Dieser Ringraum (92) steht mit dem Spalt (50) in Verbindung. Dabei wird der durch den Ringraum (92) aufsteigende Abluftstrom (91) an einer in den Ringraum (81) hineinragenden Oberkante (93) der Innenwandung (83) umgelenkt und in einen Ringraum (94) gesaugt, der von der Innenwandung (83) des Sperrwasserbehälters (82) einerseits und der in den Sperrwasserbehälter (82) hineinragenden Umbörtelung (77) andererseits gebildet wird. In diesen Ringraum (94) gelangt der Abluftstrom (91) bis zu einem in den Sperrwasserbehälter (82) hineinragenden unteren Ende (95) der Umbörtelung (77) und wird dort ein weiteres Mal in den vom Mantelteil (65) der Glocke (63) einerseits und der Umbörtelung (77) andererseits begrenzten Spaltraum (90) gelenkt. In diesem Spaltraum (90) steigt der Abluftstrom (91) innerhalb der Glocke (63) in Richtung auf den Glockenboden (66) auf und wird am oberen Ende (76) der Verjüngung (67) umgelenkt in Richtung auf den Innenraum (41) des Absaugrohres (29).This exhaust air flow (91) is from the gap (50) through an annular space (92) sucked in by the annular inner wall (83) on the one hand and the outer surface (78) of the taper (67) on the other is formed. This annular space (92) stands with the gap (50) in connection. The ascending through the annular space (92) Exhaust air flow (91) on a protruding into the annular space (81) The upper edge (93) of the inner wall (83) is deflected and into an annular space (94) sucked by the inner wall (83) of the sealing water tank (82) on the one hand and in the sealing water tank (82) protruding edging (77) is formed on the other hand. In this annular space (94) reaches the exhaust air flow (91) the sealing water tank (82) protruding lower end (95) of the Edging (77) and is there again in the from the jacket part (65) the bell (63) on the one hand and the edging (77) on the other limited gap space (90) directed. In this gap room (90) the exhaust air flow (91) inside the bell (63) rises Direction on the bell bottom (66) and is at the top (76) of the taper (67) deflected towards the interior (41) of the suction pipe (29).
Diese Führung des Abluftstromes (91) setzt voraus, daß im Sperrwasserbehälter (82) kein Sperrwasser (96) steht. Dieses Sperrwasser (96) dient bei gefülltem Sperrwasserbehälter (82) dazu, einen Geruchverschluß zu erzeugen, mit dessen Hilfe aiis dem Abwassersystem (28) über die Abluftleitung (37) in den Innenraum (41) eindringende Abluft davon abgehalten wird, in den Spaltraum (50) und damit in das Toilettenbecken (4) zu gelangen. Zu diesem Zwecke steht das Sperrwasser (96) bei gefülltem Sperrwasserbehälter (82) auf einem Pegel (97), so daß sowohl der Ringraum (94) als auch der Spaltraum (90) mindestens teilweise mit Sperrwasser (96) gefüllt sind und das untere Ende (95) der Umbörtelung (77) in das Sperrwasser (96) hineinragt. In diesem gefüllten Zustand des Sperrwasserbehälters (82) kann ein Abluftstrom (91) zwischen dem Spalt (50) einerseits und dem Innenraum (41) des Absaugrohres (29) nicht zustande kommen.This guidance of the exhaust air flow (91) presupposes that in the sealing water tank (82) there is no sealing water (96). This sealing water (96) is used to fill a sealing water tank (82) To create an odor trap, with the help of which the sewage system (28) penetrating into the interior (41) via the exhaust air line (37) Exhaust air is prevented from entering the gap (50) and to get into the toilet bowl (4). For this purpose is the sealing water (96) when the sealing water tank (82) is full at a level (97) so that both the annular space (94) and the Gap space (90) at least partially filled with sealing water (96) are and the lower end (95) of the edging (77) in the sealing water (96) protrudes. In this filled state of the sealing water tank (82) there can be an exhaust air flow (91) between the gap (50) on the one hand and the interior (41) of the suction pipe (29) not occurrence.
Um einen solchen Abluftstrom (91) durch den Sperrwasserbehälter (82) erzeugen zu können, muß der Pegel (97) des Sperrwassers (96) mindestens soweit abgesenkt werden, daß das untere Ende (95) oberhalb eines im Sperrwasserbehälter (82) abgesenkten Pegels (98) endet. Die Absenkung des Pegels (97) geschieht mit Hilfe eines Verdrängerkörpers (99), der in den Sperrwasserbehälter (82) abgesenkt werden kann und dabei das im Sperrwasserbehälter (82) stehende Sperrwasser (96) aus dem Sperrwasserbehälter (82) verdrängt. Zu diesem Zwecke besitzt der Verdrängerkörper (99) ein Volumen, das der zu verdrängenden Menge des Sperrwassers (96) entspricht. Dieser Verdrängerkörper (99) ist unmittelbar an den Mantelteil (65) der Glocke (63) angeformt und besitzt einen im wesentlichen U-förmigen Querschnitt, dessen innerer Schenkel (100) vom Mantelteil (65) der Glocke (63) gebildet wird, mit dem ein dem inneren Schenkel (100) weitgehend planparallel verlaufender äußerer Schenkel (101) über ein Joch (102) verbunden ist. Dieses Joch (102) verläuft weitgehend planparallel zum Boden (85) des Sperrwasserbehälters (82), während der äußere Schenkel (101) weitgehend planparallel zur ringförmigen Außenwandung (88) verläuft. Dabei ist zwischen dem äußeren Schenkel (101) und der ringförmigen Außenwandung (88) ein Spaltraum (103) ausgebildet, durch den das aus dem Sperrwasserbehälter (82) verdrängte Sperrwasser (96) aufsteigen und sich über einen die ringförmige Außenwandung (88) begrenzende obere Berandung (104) in den Innenraum (2) des Gehäuses (1) ergießen kann. Darüber hinaus ist es auch möglich, daß das Sperrwasser (96) beim Absenken des Verdrängerkörpers (99) im Ringraum (94) aufsteigt und sich über die Oberkante (93) der ringförmigen Innenwandung (83) des Sperrwasserbehälters (82) in den Spalt (50) ergießt. Durch den Spalt (50) läuft das verdrängte Sperrwasser (96) über die Absaugleitung (26) in das Toilettenbecken (4) ab. Dabei kann durch eine entsprechende Bemessung der ringförmigen Innenwandung (83) einerseits bzw. der ringförmigen Außenwandung (88) andererseits darauf Einfluß genommen werden, ob die Verdrängung des Sperrwassers (96) in Richtung auf den Innenraum (2) oder in Richtung auf den Spalt (50) vorgenommen werden soll. Je nach getroffener Wahl wird entweder die ringförmige Außenwandung (88) niedriger als die Innenwandung (83) ausgebildet oder umgekehrt.To such an exhaust air flow (91) through the sealing water tank (82), the level (97) of the sealing water (96) be lowered at least so far that the lower end (95) above a level (98) lowered in the sealing water tank (82) ends. The level (97) is lowered with the aid of a displacer (99), which is lowered into the sealing water tank (82) can be while standing in the sealing water tank (82) Seal water (96) displaced from the seal water tank (82). To For this purpose, the displacement body (99) has a volume that corresponds to the amount of sealing water (96) to be displaced. This Displacer body (99) is directly on the jacket part (65) the bell (63) is molded and has a substantially U-shaped Cross section, the inner leg (100) of the jacket part (65) of the bell (63) is formed, with which the inner leg (100) largely flat parallel outer leg (101) is connected via a yoke (102). This yoke (102) runs largely plane-parallel to the bottom (85) of the sealing water tank (82), while the outer leg (101) largely runs plane-parallel to the annular outer wall (88). Here is between the outer leg (101) and the annular Outer wall (88) formed a gap space (103) through which the displaced sealing water (96) rise from the sealing water tank (82) and is delimited by an annular outer wall (88) upper edge (104) in the interior (2) of the housing (1) can pour. In addition, it is also possible that the Sealing water (96) when lowering the displacer (99) in the annulus (94) rises and over the upper edge (93) of the annular Inner wall (83) of the sealing water tank (82) in the gap (50) pours. The displaced sealing water runs through the gap (50) (96) via the suction line (26) into the toilet bowl (4) from. The ring-shaped can be dimensioned accordingly Inner wall (83) on the one hand or the annular outer wall (88) on the other hand, influence whether the repression the sealing water (96) towards the interior (2) or in the direction of the gap (50). Depending on The choice made is either the annular outer wall (88) formed lower than the inner wall (83) or vice versa.
Die Absenkung des Verdrängerkörpers (99) geschieht in der Weise, daß die Glocke (63) in Richtung auf den Innenraum (2) verschoben wird. Dabei wird durch den Verdrängerkörper (99) das Sperrwasser (96) aus dem Sperrwasserbehälter (82) verdrängt. Nach der Verdrängung des Sperrwassers (96) wird die Glocke (63) durch eine Feder (105) wieder angehoben, die sich einerseits am oberen Ende (76) der Verjüngung (67) und andererseits auf einer dem Innenraum (64) zugewandten Innenfläche des Glockenbodens (66) abstützt. Diese Feder (105) ist als eine konische Spiralfeder ausgebildet, die bei der Rückführung der in den Innenraum (2) abgesenkten Glocke (63) als Druckfeder arbeitet. Falls die Glocke (63) aus dem Innenraum (2) über das Niveau des Deckels (9) herausgezogen wird, wirkt die Feder (105) zum Zwecke der Rückführung der Glocke (63) als eine Zugfeder.The sinker (99) is lowered in such a way that the bell (63) moved towards the interior (2) becomes. The sealing water is thereby through the displacement body (99) (96) displaced from the sealing water tank (82). After the repression the sealing water (96) is the bell (63) by a spring (105) raised again, which is on the one hand at the upper end (76) the taper (67) and on the other hand on the interior (64) supports facing inner surface of the bell bottom (66). That feather (105) is designed as a conical spiral spring, which at the return of the bell (63) lowered into the interior (2) works as a compression spring. If the bell (63) from the interior (2) is pulled out over the level of the cover (9), the Spring (105) for the purpose of returning the bell (63) as one Tension spring.
Dieser Fall tritt ein, wenn nach einer Öffnung des Spülventils (49) dieses wieder verschlossen werden soll. Zum Zwecke des Öffnens des Spülventils (49) wird der mit der Verlängerung (30) verbundene Ventilteil (53) vom Ventilsitz (52) abgehoben. Die Anhebung der Verlängerung (30) geschieht mit Hilfe der Glocke (63). An diese ist über den Verdrängerkörper (99) der Sperrwasserbehälter (82) angekoppelt. Zu diesem Zwecke besitzt der Sperrwasserbehälter (82) an seiner Außenwandung (88) mindestens zwei diametral angeordnete Kupplungsteile (106), die als ein in Richtung auf den Verdrängerkörper (99) vorragender Vorsprung (107) ausgebildet sind. Unter diesen Vorsprung (107) faßt der Verdrängerkörper (99) mit einer am äußeren Schenkel (101) ausgebildeten Oberkante (108). Wird die Glocke (63) und damit der Verdrängerkörper (99) aus dem Deckel (9) herausgezogen, so faßt die Oberkante (108) unter den Vorsprung (107) und hebt dabei den Sperrwasserbehälter (82) und mit ihm die Verlängerung (30) an, die über die Steckverbindung (87) fest mit dem Sperrwasserbehälter (82) verbunden ist. Auf diese Weise wird das Ventilteil (53), das fest mit der Verlängerung (30) verbunden ist, vom Ventilsitz (52) abgehoben, so daß sich das Spülventil (49) öffnet. Danach wird die Glocke (63) wieder in Richtung auf den Innenraum (2) abgesenkt, so daß der Verdrängerkörper (99) vom Sperrwasserbehälter (82) im Bereich des Kupplungsteils (106) abgekoppelt wird. Auf Grund des Eigengewichts der mit dem Sperrwasserbehälter (82) fest verbundenen Verlängerung (30) senkt sich das Ventilteil (53) wieder auf den Ventilsitz (52) und verschließt damit das Spülventil (49). Vom Joch (102) des Verdrängungskörpers (99) ragt ein Ring (109) in Richtung auf den Sperrwasserbehälter (82). Dieser Ring (109) taucht mit seinem dem Joch (102) abgewandten Rand (110) in eine Restwassermenge (111) ein, und verhindert auf diese Weise, daß Luft aus dem Gehäuse (1) über den Spaltraum (103) angesaugt wird, der zwischen dem äußeren Schenkel (101) und der ringförmigen Außenwandung (88) ausgebildet ist.This happens when after opening the purge valve (49) this should be closed again. For the purpose of opening the flushing valve (49) is connected to the extension (30) Lift valve part (53) off valve seat (52). The raise the extension (30) is done with the help of the bell (63). On this is the sealing water tank via the displacer (99) (82) coupled. For this purpose, the sealing water tank has (82) on its outer wall (88) at least two diametrically arranged Coupling parts (106) acting as one towards the displacer (99) protruding projection (107) are formed. Under this projection (107) the displacer body (99) is included an upper edge (108) formed on the outer leg (101). If the bell (63) and thus the displacement body (99) from the Pulled out the cover (9), the upper edge (108) grips under the Projection (107) and lifts the sealing water tank (82) and with it the extension (30) on the connector (87) is firmly connected to the sealing water tank (82). On this way the valve part (53) that is fixed to the extension (30) is connected to the valve seat (52) so that the purge valve (49) opens. Then the bell (63) is back lowered towards the interior (2) so that the displacer (99) from the sealing water tank (82) in the area of Coupling part (106) is uncoupled. Because of its own weight the extension firmly connected to the sealing water tank (82) (30) the valve part (53) lowers again onto the valve seat (52) and thus closes the flush valve (49). From the yoke (102) of the sinker (99) protrudes a ring (109) towards the Sealing water tank (82). This ring (109) dips with its Edge (110) facing away from the yoke (102) into a residual amount of water (111) and in this way prevents air from the housing (1) is sucked in through the gap (103) which is between the outer Leg (101) and the annular outer wall (88) formed is.
Es ist auch möglich, den Sperrwasserbehälter (82) mit Wandungen (300,301) zu versehen, die im Querschnitt des Sperrwasserbehälters (82) in Richtung auf das Spülventil konisch aufeinander zulaufen. Darüber hinaus laufen auch die Wandungen (302,303) des Verdrängerkörpers (99) konisch in Richtung auf das Spülventil (49). Dabei laufen die Wandungen (302,303) den Wandungen (300,301) im wesenlichen planparallel. Schließlich ist auch die Umbörtelung (77) als eine konische Wandung (304) ausgebildet, die im wesentlichen planparallel zu den Wandungen (301,303) verläuft und in den zwischen diesen beiden Wandungen (301,303) vorhandenen Ringraum (94) hineinragt. Diese konische Ausbildung der Wandung (300,301; 302,303 ; 304) besitzt den großen Vorteil, daß bereits bei kleinen Bewegungen des Verdrängerkörpers (99) in Richtung auf das Spülventil (49) relativ große Anteile des im Sperrwasserbehälter (82) stehenden Sperrwassers verdrängt werden. Darüber hinaus lösen sich die konischen Wandungen (302,303) vergleichsweise leicht von den ihnen jeweils benachbahrten konischen Wandungen (300,304), wenn nach einer Ansenkung des Verdrängerkörpers (99) dieser unter Mitwirkung der Federspannung der Spiralfeder (105) wieder angehoben wird, um der durch den Ablaufstutzen (13) angesaugten Abluft den Durchgang in Richtung auf das Absaugrohr (29) zu er möglichen.It is also possible to have the sealing water tank (82) with walls (300,301) to be provided in the cross section of the sealing water tank (82) taper towards each other in the direction of the flushing valve. In addition, the walls (302, 303) of the displacement body also run (99) conical towards the flushing valve (49). Here the walls (302,303) essentially run the walls (300,301) plane parallel. Finally, the edging (77) is as a conical wall (304) is formed which is essentially runs parallel to the walls (301,303) and in the between these two walls (301, 303) existing annular space (94) protrudes. This conical formation of the wall (300,301; 302,303; 304) has the great advantage that even with small Movements of the displacer (99) towards the flush valve (49) relatively large portions of the in the sealing water tank (82) standing sealing water are displaced. They also come off the conical walls (302,303) comparatively slightly from the conical walls (300, 304) adjacent to them, if after lowering the displacer (99) this with the participation the spring tension of the spiral spring (105) is raised again is to the exhaust air sucked in through the drain pipe (13) Passage towards the suction pipe (29) possible.
Die Füllung des Sperrwasserbehälters (82) kann mit Hilfe einer Bypassleitung (114) erfolgen, die den Sperrwasserbehälter (82) mit einem Spülwasserzulauf (115) verbindet, durch die das Spülwasser (48) in den Innenraum (2) eingeleitet wird. Es ist jedoch auch möglich, die gesamte Füllung des Innenraumes (2) mit Spülwasser (48) dadurch vorzunehmen, daß das Spülwasser zunächst in den Sperrwasserbehälter (82) eingeleitet wird. Nachdem dieser gefüllt worden ist, tritt das Spülwasser (48) durch einen Überlauf des Sperrwasserbehälters (82) in den Innenraum (2) ein.The filling of the sealing water tank (82) can be done with the help of a bypass line (114) take place with the sealing water tank (82) connects a rinse water inlet (115) through which the rinse water (48) is introduced into the interior (2). However, it is also possible to fill the entire interior (2) with rinse water (48) by first rinsing the water in the Sealing water tank (82) is introduced. After this is filled has been, the rinse water (48) occurs through an overflow of the Sealing water tank (82) into the interior (2).
Die Steuerung des Antriebs (43) erfolgt mit Hilfe eines Reetkontaktes (116), der über eine Steuerleitung (117) mit dem Antrieb (43) verbunden ist. Dieser Reetkontakt (116) wird von einem Magneten (118) betätigt, der in einen Schwimmer (119) eingebettet ist. Dieser Schwimmer (119) schwimmt im Sperrwasserbehälter (82). Sobald im Sperrwasserbehälter (82) das Sperrwasser (96) abgesenkt worden ist, sinkt der Schwimmer (119) im Sperrwasserbehälter (82) ab, so daß der Magnet (118) den Reetkontakt (116) betätigen kann. Zu diesem Zwecke ist der Reetkontakt (116) innerhalb des Absaugrohres (29) in Höhe des im sperrwasserbehälter (82) abgesenkten Sperrwasserpegels angebracht. Nachdem der Reetkontakt (116) betätigt worden ist, wird der Antrieb (43) über eine Versorgungsleitung (120) mit Strom versorgt, so daß der Unterdruckerzeuger (42) anlaufen kann und Luft aus dem Sperrwasserbehälter (82) ansaugen kann. Er drückt die angesaugte Luft durch die Abluftleitung (37) in das Abwassersystem (28).The drive (43) is controlled with the help of a reed contact (116) via a control line (117) with the drive (43) is connected. This thatched contact (116) is made by a magnet (118) actuated, which is embedded in a float (119). This float (119) floats in the sealing water tank (82). As soon as the sealing water (96) is lowered in the sealing water tank (82) the float (119) sinks in the sealing water tank (82) so that the magnet (118) can actuate the reed contact (116). For this purpose the thatched contact (116) is inside the suction tube (29) in the amount of the lowered in the sealing water tank (82) Barrier water level attached. After the reed contact (116) is actuated has been, the drive (43) via a supply line (120) powered so that the vacuum generator (42) can start up and suck in air from the sealing water tank (82) can. It pushes the sucked-in air through the exhaust air line (37) into the sewage system (28).
Um eine gute Funktion des Reetkontaktes (116) gewährleisten zu können, muß der Magnet (118) und damit der Schwimmer (119) nicht nur in lotrechter Richtung gegenüber dem Reetkontakt (116) genau ausgerichtet sein, sondern der Reetkontakt (116) muß auch in der durch ihn verlaufenden Ebene dem Magneten (118) genau gegenüber liegen. Um in soweit eine genaue Ausrichtung des Sperrwasserbehälters (82), in dem der Schwimmer (119) mit dem in ihm eingeschlossenen Magneten (118) schwimmt, gegenüber dem Absaugrohr (29), in dem der Reetkontakt (116) befestigt ist, vornehmen zu können, ist zwischen dem Absaugrohr (29) und der Verlängerung (30), auf der der Sperrwasserbehälter (82) befestigt ist, eine Justierung (305) vorgesehen. Diese Justierung ist in dem Spalt (50) angeordnet, der sich zwischen dem Absaugrohr (29) einerseits und der Verlängerung (30) andererseits erstrechkt. Diese Justierung (305) ist in Form von Gleitstücken (306,307,308) ausgebildet, die sich in einem vorgegebenen Abstand (309) voneinander gegenseitig beaufschlagen. Dabei sind die Gleitstücke (306,308) auf einer in den Spalt (50) weisenden Innenoberfläche (310) der Verlängerung (30) angeordent, während das Gleitstück (307) auf einer in den Spalt (50) weisenden Außenoberfläche (311) des Absaugrohrens (29) befestigt ist. Zwischen den beiden äußeren Gleitstücken (306,308) ist ein Abstand (309) vorgesehen, dessen Weite der Breite des Gleitstückes (307) entspricht. Wenn die Verlängerung (30) mit dem auf ihr befestigten Sperrwassrbehälter (82) auf das Absaugrohr (29) aufgesteckt wird, gleitet das Gleitstück (307) in den Abstand (309) hinein, der zwischen den beiden Gleitstücken (306,308) vorgesehen ist. In dieser Ausrichtung ist dafür Sorge getragen, daß der Reetkontakt (116) dem im Schwimmer (119) eingeschlossenen Magneten (118) genau gegenüber liegt.To ensure that the reed contact (116) functions properly can, the magnet (118) and thus the float (119) does not have to only in the vertical direction with respect to the thatched contact (116) aligned, but the thatched contact (116) must also in the through the plane running exactly opposite the magnet (118) lie. In order for the exact alignment of the sealing water tank (82), in which the float (119) with the enclosed in it Magnet (118) floats in, opposite the suction pipe (29) to which the thatched contact (116) is attached, can be made between the suction pipe (29) and the extension (30) on the the sealing water tank (82) is attached, an adjustment (305) intended. This adjustment is arranged in the gap (50) between the suction pipe (29) on the one hand and the extension (30) on the other hand. This adjustment (305) is in shape of sliders (306,307,308) formed in a predetermined Apply distance (309) to each other. Here are the sliders (306,308) on one in the gap (50) facing inner surface (310) of the extension (30), while the slider (307) on one in the gap (50) facing External surface (311) of the suction pipe (29) is attached. Between the two outer sliders (306,308) is a distance (309) provided, the width of the width of the slider (307) corresponds. If the extension (30) with the attached on it Sealing water tank (82) is plugged onto the suction pipe (29), slides the slider (307) into the distance (309) between the two sliders (306,308) is provided. In this Alignment is ensured that the thatched contact (116) exactly opposite the magnet (118) enclosed in the float (119) lies.
Die Versorgungsleitung (120) kann beispielsweise durch das Anschlußstück (31) in Richtung auf das mit der Abluftleitung (37) verbundene Anschlußende (35) des Absaugrohres (29) geführt werden. Sie wird luftdicht aus dem Ende (36) herausgeführt und in Richtung auf ein Netzteil (121) geleitet, das in einer für diese Zwecke vorgesehenen Ausnehmung (122) des Gehäuses (1) befestigt ist. Dieses Netzteil (121) ist über ein Kabel (123) mit dem öffentlichen Netz verbunden.The supply line (120) can, for example, through the connector (31) in the direction of that with the exhaust air line (37) connected connecting end (35) of the suction pipe (29) are guided. It is led hermetically out of the end (36) and in the direction passed to a power supply (121), which is in a for this purpose provided recess (122) of the housing (1) is attached. This Power supply (121) is connected to the public via a cable (123) Network connected.
Vor der Benutzung des Toilettenbeckens (4) wird zunächst der Verdrängerkörper (99) in den Sperrwasserbehälter (82) abgesenkt und auf diese Weise das Sperrwasser (96) aus dem Sperrwasserbehälter (82) verdrängt. Dadurch sinkt der Schwimmer (119) im Sperrwasserbehälter (82) ab, so daß der Magnet (118) den Reetkontakt (116) betätigen kann. Daraufhin läuft der Antrieb (43) an, so daß Abluft aus dem Toilettenbecken (4) über den Spalt (50) und den Innenraum (41) des Absaugrohres (29) abgesaugt werden kann.Before using the toilet bowl (4), first the displacer (99) lowered into the sealing water tank (82) and in this way the sealing water (96) from the sealing water tank (82) ousted. This causes the float (119) to sink in the sealing water tank (82), so that the magnet (118) the reed contact (116) can operate. Then the drive (43) starts, so that exhaust air from the toilet bowl (4) over the gap (50) and the interior (41) of the suction pipe (29) can be suctioned off.
Die Feder (105) drückt die gemeinsam mit dem Sperrwasserbehälter (82) abgesenkte Glocke (63) wieder in ihre Ausgangsposition, in der sie im Bereich des Kupplungsteils (106) an den Sperrwasserbehälter (82) angekoppelt ist. Zum Zwecke der Spülung wird die Glocke (63) aus dem Deckel (9) herausgezogen. Gemeinsam mit dem an den Verdrängerkörper (99) angekoppelten Sperrwasserbehälter (82) wird dabei auch die Verlängerung (30) angehoben, so daß das Ventilteil (53) den Ventilsitz (52) verläßt. Dadurch wird das Spülventil (49) geöffnet, so daß das Spülwasser (48) in die Absaugleitung (26) eintreten kann. Nach Vornahme der Spülung senkt sich die Verlängerung (30) und das mit ihr verbundene Ventilteil (53) in Richtung auf den Ventilsitz (52) ab, so daß das Spülventil (49) verschlossen wird.The spring (105) presses it together with the sealing water tank (82) lowered bell (63) back to its starting position, in which in the area of the coupling part (106) to the sealing water tank (82) is coupled. For the purpose of flushing Bell (63) pulled out of the cover (9). Together with that the displacement water tank (82) coupled to the displacer (99) the extension (30) is also raised, so that the valve part (53) leaves the valve seat (52). This will make the purge valve (49) opened so that the rinse water (48) in the suction line (26) can occur. After the rinse has been carried out, it lowers Extension (30) and the valve part (53) connected to it in Direction on the valve seat (52), so that the flush valve (49) is closed.
Es ist auch möglich, die Betätigung der Glocke (63) mit Hilfe eins Hubmagneten (124) vorzunehmen. Diese Art der Betätigung der Glocke (63) wird insbesondere bei solchen Spülkästen bevorzugt angewendet, die in eine Wand eingebaut werden.It is also possible to actuate the bell (63) using one Make solenoids (124). This way of operating the bell (63) is particularly preferred for such cisterns, which are built into a wall.
Darüber hinaus ist denkbar, das Netzteil (130) in das Gehäuse (1) unterhalb des Deckels (9) zu verlegen. Auf diese Weise kann mit dem Deckel (9) auch das Netzteil (130) vom Gehäuse (1) abgenommen werden.It is also conceivable to insert the power supply unit (130) into the housing (1) to be laid below the cover (9). That way, with the cover (9) and the power pack (130) are removed from the housing (1) will.
Zur weiteren Justierung der Ablaufgarnitur (3) innerhalb des Innenraumes (2) ist es möglich, die Lage des Ablaufstutzens (13) und damit des Ventilsitzes (52) gegenüber dem mit dem Spülknopf (62) verbundenen Verdrängerkörper (99) genau festzulegen. Dieser Verdrängerkörper (99) kann nur im Rahmen der von der Glocke (63) durchführbaren Bewegungen bewegt werden. Auf diese Weise ist es denkbar, daß der Verdrängerkörper (99) mit seinem Joch (102) nicht soweit in den Sperrwasserbehälter (82) vordringt, daß genügend Sperrwassr (96) aus dem Sperrwasserbehälter (82) verdrängt wird. Da die Lage der Glocke (63) vom Deckel (9) vorgegeben ist, kann bezüglich des Verdrängerkörpers (99) nur der Sperrwasserbehälter (82) gemeinsam mit der Verlängerung (30) und dem Ventilsitz (52) ausgerichtet werden. Zu diesem Zwecke kann der Ventilsitz (52) hinsichtlich seiner Höhe gegenüber dem Boden dadurch variiert werden, daß eine mehr oder minder große Anzahl von Abstandsringen (23) zwischen die Mutter (20) und den Boden (7) gelegt werden. Sollte der Verdrängerkörper (99) mit seinem Joch (102) nicht bis zur vollen Tiefe in den Sperrwasserbehälter (82) abgesenkt werden können, so muß durch Wahl eines zusätzlichen Abstandsringes (23) dafür gesorgt werden, daß der Sperrwasserbehälter (82) in Richtung auf den Deckel (9) angehoben wird.For further adjustment of the waste set (3) inside the interior (2) it is possible to determine the position of the drain connector (13) and thus the valve seat (52) compared to the one with the flush button (62) connected displacer (99) precisely. This displacement body (99) can only be used within the scope of the bell (63) feasible movements are moved. That way it is conceivable that the displacer (99) with its yoke (102) is not so far in the sealing water tank (82) penetrates that enough Barrier water (96) is displaced from the barrier water tank (82). Since the position of the bell (63) from the cover (9) is predetermined, can with regard to the displacement body (99) only the sealing water tank (82) together with the extension (30) and the valve seat (52) be aligned. For this purpose the valve seat (52) can be varied in terms of its height from the ground that a more or less large number of spacer rings (23) between the nut (20) and the bottom (7). If the displacer (99) with its yoke (102) is not up to to the full depth in the sealing water tank (82) must, by choosing an additional spacer ring (23) be ensured that the sealing water tank (82) in the direction is lifted onto the cover (9).

Bei geschlossenem Spülventil (49) saugt der Unterdruckerzeuger (42), der im Absaugrohr (29) befestigt ist, die Abluft durch den Ablaufstutzen (13), der über die Absaugleitung (26) mit dem Toilettenbecken (4) verbunden ist. Diese Abluft tritt durch die Verlängerung (30) in den Innenraum (64) der Glocke (63) ein und wird durch den vom Sperrwasser entleerten Sperrwasserbehälter (82) in das Absaugrohr (29) gesaugt. Von dort gelangt die Abluft durch die Verbindungsleitung (199) in den Ring (200) und tritt durch die Zugangsöffnung (202) in den Ringraum (312) ein. Aus diesem gelangt die Abluft über die Zugangsöffnung (203) in den Ring (201), aus dem sie in Richtung auf das Anschlußstück (31) herausgedrückt wird. Dieses ist beispielsweise mit dem Abwassersystem (28) verbunden, daß die Abluft aufnimmt.When the flush valve (49) is closed, the vacuum generator sucks (42), which is fixed in the suction pipe (29), the exhaust air through the Drain pipe (13), which is connected to the toilet bowl via the suction line (26) (4) is connected. This exhaust air passes through the extension (30) in the interior (64) of the bell (63) and will through the sealing water tank (82) emptied from the sealing water the suction pipe (29) sucked. From there, the exhaust air passes through the Connection line (199) in the ring (200) and passes through the access opening (202) into the annular space (312). Got out of this the exhaust air via the access opening (203) into the ring (201) which they pushed out towards the connector (31) becomes. This is connected, for example, to the sewage system (28) that the exhaust air picks up.

The extension (68) can be are turned with the taper (67) relative to the main part (39), so that an exact alignment of the reed contact (116) opposite the position of the magnet enclosed in the float (119) (118) is possible.
Um beim Absenken des im Sperrwasserbehälter (82) stehenden Pegels (97) des Sperrwassers (96) zu verhindern, daß der Verdrängerkörper (99) das Sperrwasser (96) in den Spaltraum (90) anhebt und damit die Gefahr erzeugt, daß das Sperrwasser (96) in den Innenraum (41) und damit in Richtung auf den Unterdruckerzeuger (42) abfließt, sind innerhalb des Spaltraumes (90) Sperren (125) vorgesehen, die entweder auf einer Innenwandung des Mantelteils (65) der Glocke (63) oder auf einer in den Spaltraum (90) weisenden Außenwandung der Umbörtelung (77) vorgesehen sein können. Diese Sperren (125) können sich in Form von mindestens einem Ring bzw. von mehreren Teilringen so durch den Spaltraum (90) erstrecken, daß ein Aufsteigen des Sperrwassers (96) im Spaltraum (90) ausgeschlossen ist, daß jedoch noch genügend Freiraum verbleibt, um die Abluft aus dem Sperrwasserbehälter (82) in Richtung auf den Innenraum (41) des Absaugrohres (29) absaugen zu können.To lower the level in the sealing water tank (82) (97) of the sealing water (96) to prevent the displacer (99) the sealing water (96) in the gap space (90) and thus creates the danger that the sealing water (96) into the interior (41) and thus flows in the direction of the vacuum generator (42), locks (125) are provided within the gap space (90) either on an inner wall of the casing part (65) of the bell (63) or on an outer wall pointing into the gap (90) the edging (77) can be provided. These locks (125) can be in the form of at least one ring or several Extend partial rings through the gap (90) so that an ascent the sealing water (96) in the gap space (90) excluded is that, however, there is still enough free space for the exhaust air from the sealing water tank (82) towards the interior (41) of the suction pipe (29).
Andererseits kann zur Erleichterung des Abflusses von Sperrwasser (96) aus dem Sperrwasserbehälter (82) an der ringförmigen Innenwandung (83) des Sperrwasserbehälters (82) ein Überlauf (133) vorgesehen sein, in dessen Bereich die Oberkante (93) der ringförmigen Innenwandung (83) abgesenkt ist. Beim Absenken des Verdrängerkörpers (99) ergießt sich die verdrängte Sperrwassermenge (96) durch den Überlauf (133) in die Verlängerung (30), durch die sie in Richtung auf das Toilettenbecken (4) abfließt.On the other hand, can facilitate the outflow of sealing water (96) from the sealing water tank (82) on the annular inner wall (83) of the sealing water tank (82) an overflow (133) is provided be in the area of the upper edge (93) of the annular Inner wall (83) is lowered. When lowering the displacer (99) the displaced quantity of sealing water pours out (96) through the overflow (133) into the extension (30) through which it flows towards the toilet bowl (4).
Eine Steuerung des Spülventils (49) kann mit Hilfe eines ringförmigen Schwimmers (313) vorgenommen werden, der ringförmig die Verlängerung (30) unmgibt. Dabei ist zwischen einer der Verlängerung (30) zugewandten inneren Oberfläche (314) des Schwimmers (313) und einer ihr zugewandten äußeren Oberfläche (315) der Verlängerung (30) ein Spiel (316) vorgesehen, so daß der Schwimmer (313) leicht bezüglich der Verlängerung (30) an deren äußeren Oberfläche (315) entlang bewegt werden kann. Der Schwimmer (313) ist über einen Klemmring (317) an die Verlängerung (30) angekoppelt. Dieser Klemmring (317) haftet auf der äußeren Oberfläche (315) klemmend, so daß er bezüglich der von Schwimmer (313) erwarteten Steuerung der Verlängerung (30) höher oder niedriger auf der äußeren Oberfläche (315) justiert werden kann.The flush valve (49) can be controlled with the aid of an annular Float (313) are made, the extension ring-shaped (30) impossible. There is an extension between one (30) facing inner surface (314) of the float (313) and an outer surface (315) of the extension facing it (30) a game (316) is provided so that the float (313) easily with respect to the extension (30) on its outer surface (315) can be moved along. The float (313) is over one Clamping ring (317) coupled to the extension (30). This Clamping ring (317) adheres to the outer surface (315), so that it is regarding the control expected by float (313) the extension (30) higher or lower on the outer surface (315) can be adjusted.
Der im Spülwasser schwimmende Schwimmer (313) beaufschlagt mit seiner dem Spülknopf (62) zugewandten Oberkante (318) den Klemmring (317) auf seiner dem Spülventil (49) zugewandten Unterkante (319). Auf diese Weise wird erreicht, daß bei der Spülung der im Spülwasser aufschwimmende Schwimmer (313) über den Klemmring (317) die Verlängerung (30) anhebt und auf diese Weise das Spülventil (49) geöffnet wird.The float (313) floating in the rinsing water acts on it its top edge (318) facing the flush button (62) has the clamping ring (317) on its lower edge facing the flushing valve (49) (319). In this way it is achieved that in the flushing of the Float (313) floating in flushing water via the clamping ring (317) the extension (30) lifts and in this way the flush valve (49) is opened.
In einer von Spülventil (49) relativ großen Entfernung wird der Klemmring (317) in einer oberen Position auf der äußeren Oberfläche (315) der Verlängerung (30) befestigt. In dieser oberen Position steuert der Schwimmer (313) eine vergleichsweise kurze Öffnungszeit der Spülventils (49), gegenüber einer dem Spülventil (49) zugewandten unteren Position des Klemmringes (317).At a relatively large distance from the flush valve (49) Clamping ring (317) in an upper position on the outer surface (315) of the extension (30) attached. In this top position the float (313) controls a comparatively short opening time the flush valve (49), opposite one of the flush valve (49) facing lower position of the clamping ring (317).
Zu diesem Zwecke besitzt des Schwimmer (313) ein Auftriebskraft, die geringer ist, als das mit der Verlängerung (30) verbundene bewegiche Teil der Ablaufgarnitur (3). Auf diese Weise wird erreicht, daß das geöffnete Spülventil (49) auf Grund des Gewichtes des beweglichen Teils wieder verschlossen wird. Die Öffnung des Spülventils (49) ist abhängig von der Auftriebskraft des Schwimmers (313) und der Stelle, an der der Klemmring (317) an der Verlängerung (30) befestigt ist. Entsprechend der Wasseraufnahme des Toilettenbeckens (4) kann die Auftriebskraft des Schwimmers (313) so bemessen sein, daß die aus dem Spülventil (49) austretende Spülwassermenge beispielsweise entweder 6 Liter oder 9 Liter beträgt.For this purpose, the float (313) has a buoyancy force, which is less than that associated with the extension (30) Movable part of the waste set (3). In this way it is achieved that the opened flush valve (49) due to the weight of the movable part is closed again. The opening of the Flush valve (49) depends on the buoyancy of the float (313) and the place where the clamping ring (317) on the extension (30) is attached. According to the water absorption of the Toilet bowl (4) the buoyancy of the float (313) be dimensioned such that the exiting from the flushing valve (49) The amount of rinse water, for example, is either 6 liters or 9 liters.
Um eine gleichmäßige Steuerung der aus dem Spülventil (49) austretenden Spülwassermenge bis zur volkommenen Entleerung des Gehäuses (1) gewährleisten zu können, ist im unterem Bereich der Verlängerung (30), aber oberhalb einer bei geöffnetem Spülventil (59) erreichten oberen Stellung des Ventilteils (53) ein Schwimmergehäuse (320) vorgesehen, in das der Schwimmer (313) eintaucht, nachdem ein erheblicher Teil des Spülwassers das Gehäuse (1) durch das Spülventil (4) verlassen hat. Da dieses Schwimmergehäuse (320) mit einer Innenwandung (321) und einer Außenwandung (322) gegenüber dem Innenraum (2) des Gahäuses (1) abgetrennt ist, bleibt im Schwimmergehäuse (320) auch dann das Spülwasser stehen, wenn im übrigen Innenraum (2) der Spülwasserpegel bereits unter eine dem Spülknopf (62) zugewandte Oberkante des Schwimmergehäuses (320) gefallen ist. Auf diese Weise wird erreicht, das unabhängig vom Pegel des Spülwassers innerhalb des Innenraumes (2) der Schwimmer (313) eine konstante Auftriebskraft entwickelt.To ensure even control of those emerging from the flushing valve (49) Rinse water quantity until the housing is completely emptied (1) To be able to guarantee is in the lower area of the extension (30), but above one with the flush valve (59) open upper position of the valve part (53) a float housing (320) is provided, into which the float (313) dips after a significant part of the rinse water through the housing (1) Has left the flushing valve (4). Since this float housing (320) with an inner wall (321) and an outer wall (322) opposite the interior (2) of the housing (1) is separated, remains in the Float housing (320) are also the rinse water when in the remaining interior (2) the rinse water level is already below a Flush button (62) facing the upper edge of the float housing (320) fell. In this way it is achieved that regardless of Level of the flushing water inside the float's interior (2) (313) developed a constant buoyancy.
Zu diesem Zwecke umgibt das Schwimmergehäuse (320) ringförmig die Ablaufgarnitur (3). Dabei ist zwischen der Innenwandung (321) und der äußeren Oberfläche (315) der Verlängerung ein Spalt (324) vorgesehen, der groß genug ist, damit die Verlängerung (30) sich unbeeinflußt vom Schwimmergehäuse (320) in Längsrichtung bewegen kann. Zwischen der Außenwandung (322) und der Innenwandung (321) erstreckt sich ein Innenraum (325), der groß genug ist, um den Schwimmer (313) aufzunehmen. Darüber hinaus erstreckt sich durch den Innenraum (325) eine Spiralfeder (327), die sich einerseits mit ihrem oberem Ende (328) am Klemmring (317) abstützt und andererseits mit ihrem unterem Ende (329) auf einem dem Spülventil (49) zugewandten Gehäuseboden (330). Diese Spiralfeder (327) bessitzt auch in ihrem gespannten Zustand, wenn der Schwimmer (313) in das Schwimmergehäuse (320) eingefahren ist, eine geringe Vorspannung. Diese Auftriebskraft des Schwimmers (313) reicht aus, um auch mit einer am Spülknopf (62) gering aufgebrachten Öffnungskraft das Spülventils (49) öffnen zu können. Andererseits reicht das Gewicht des beweglichen Teils der Ablaufgarnitur (3) aus, um entgegen der Spannung der Spiralfeder (327) das Spülventil (49) verschließen zu können, wobei die Verschlußgeschwindigkeit unter Berücksichtigung der von der Spiralfeder (327) entwickelten Spannung vom Schwimmer (313) gesteuert wird.For this purpose, the float housing (320) surrounds the ring Waste set (3). It is between the inner wall (321) and a gap (324) is provided on the outer surface (315) of the extension, which is large enough so that the extension (30) is not affected move lengthways from the float housing (320) can. Between the outer wall (322) and the inner wall (321) extends an interior (325) that is large enough to the Float (313) record. It also extends through the interior (325) is a coil spring (327), which on the one hand with its upper end (328) on the clamping ring (317) and on the other hand with its lower end (329) on a flush valve (49) facing housing base (330). This coil spring (327) is fitted even in their tense state when the swimmer (313) a small preload is inserted into the float housing (320). This buoyancy of the float (313) is sufficient to also with an opening force slightly applied to the flush button (62) to be able to open the flushing valve (49). On the other hand, it is enough the weight of the movable part of the waste set (3) against the tension of the spiral spring (327) the flush valve (49) to be able to close, the shutter speed below Taking into account the tension developed by the spiral spring (327) is controlled by the float (313).
Der Gehäuseboden (330) weist gegenüber dem Boden (7) des Gehäuses (1) eine Höhe auf, die mindestens so bemessen ist, daß ein einwandfreies Verschließen des Spülventils (49) gewährleistet ist. Zu diesem Zwecke muß zwischen einer in den Innenraum (325) hineinragenden Unterkante (331) des Schwimmers (313) und dem Gehäuseboden (330) ein Sicherheitsabstand vorgesehen sein, wenn das Spülventil (49) sicher geschlossen ist. Das Schwimmergehäuse (320) wird über Ablauflöcher (370), die im Gehäuseboden (330) oder seiner unmittelbaren Nähe angeordnet sind, entleert. Über die Größe dieser Ablauflöcher (370) wird die Ausflußgeschwindigkeit und damit die Schließgeschwindigkeit des Spülventils (49) gesteuert.The housing bottom (330) faces the bottom (7) of the housing (1) a height that is dimensioned at least so that a perfect Closing the flush valve (49) is guaranteed. To For this purpose, one must protrude into the interior (325) Lower edge (331) of the float (313) and the case bottom (330) A safety margin should be provided when the purge valve (49) is securely closed. The float housing (320) is about Drain holes (370) in the housing base (330) or its immediate Are arranged nearby, emptied. About the size of these drain holes (370) becomes the outflow rate and thus the Closing speed of the purge valve (49) controlled.
Das Schwimmergehäuse (320) ist gegenüber dem Boden (7) des Gehäuses (1) abgestützt. Zu diesem Zwecke sind mindestens drei über den Umfang des Schwimmergehäuses (320) etwa gleichmäßig verteilte Beine (332,333) vorgesehen. Diese Beine (332,333) sind in Richtung auf die Ablaufgarnitur (3) elastisch am Schwimmergehäuse (320) befestigt, so daß sie bei einer entsprechend aufgebrachten Kraft in der Lage sind, Bewegungen in Richtung auf die Ablaufgarnitur (3) oder in entgegengesetzter Richtung auszuführen.The float housing (320) is opposite the bottom (7) of the housing (1) supported. For this purpose, at least three are above the Circumference of the float housing (320) approximately evenly distributed Legs (332, 333) are provided. These legs (332,333) are towards on the waste set (3) on the float housing (320) attached so that they are applied accordingly Are able to make movements towards the waste set (3) or in the opposite direction.
Diese Beine (332,333) sind an ihren dem Schwimmergehäuse (320) abgewandten Enden (334) auf dem Boden (7) des Gehäuses (1) abgestützt. Zu diesem Zwecke sind auf dem Roden (7) Taschen (369) vorgesehen, die eine sich in Richtung auf die Ablaufgarnitur (3) erstreckende Öffnung (335) aufweisen. In die Öffnung (335) greift ein von der Ablaufgarnitur (3) weg gewinkeltes Endstück (336) jeweils eines Beines (332,333) ein.These legs (332, 333) are on their float housing (320) opposite ends (334) supported on the bottom (7) of the housing (1). For this purpose, pockets (369) are provided on the harvester (7), the one extending in the direction of the drain fitting (3) Have opening (335). Reaches into the opening (335) one end piece (336) angled away from the drain fitting (3) in each case one leg (332,333).
Die Taschen (334) sind als am Boden (7) befestigte Halterungsstücke ausgebildet, die mit einem hakenförmigen Dachteil (337) versehen sind, das in Richtung auf den Ablaufstutzen (13) hinweist. Unter dieses Dachteil (337) greift das Ende (336) jeweils eines Beins (332,333), wenn dieses Bein (332,333) in seiner nicht ausgelenkten Ausgangsposition ist. Um das Schwimmergehäuse (320) vom Boden (7) zu lösen, werden die Beine (332,333) elastisch in Richtung auf die Ablaufgarnitur (3) verbogen, so daß das Ende (336) aus dem hackenförmigen Dachteil (337) gelöst wird. Nunmehr kann das gesamte Schwimmergehäuse den Innenraum (2) des Gehäuses (1) entnommen werden. Die Tasche (334) kann als ein das Spülventil (49) konzentrisch umgebener Kragen (338) ausgebildet sein, dessen hakenförmiger Dachteil von einer Vielzahl von Beinen (333,332) beaufschlagt wird.The pockets (334) are attached to the floor (7) as mounting pieces formed with a hook-shaped roof part (337) are provided, which points in the direction of the drain pipe (13). The end (336) engages under this roof part (337) a leg (332,333) if that leg (332,333) is not in its is deflected starting position. Around the float housing (320) to release from the floor (7), the legs (332, 333) become elastic in Bent towards the drain fitting (3) so that the end (336) from the hook-shaped roof part (337) is released. Now the entire float housing can cover the interior (2) of the housing (1) can be removed. The bag (334) can act as a flush valve (49) concentrically surrounded collar (338), the hook-shaped roof part acted upon by a large number of legs (333, 332) becomes.
Darüber hinaus kann das Schwimmergehäuse (320) auch gegenüber der Mutter (20) justiert sein, mit der der Ablaufstutzen (13) am Boden (7) des Gehäuses (1) befestigt ist. In diesem Falle besitzt die Mutter (20) an ihrem äußerem Umfang (339) gleichmäßig verteilte Aufnahmeschlitze (340) in denen jeweils ein Bein (332,333) des Schwimmergehäuses (320) verankert ist. In diesem Falle erstrecken sich die Aufnahmeschlitze (340) von dem äußerem Umfang (339) der Mutter (20) in Richtung auf den Ablaufstutzen (13). Die in die Aufnahmeschlitze (340) eingerasteten Beine (332,333) unterfassen mit einem abgewinkelten Ende (341) einen an der Mutter (20) ausgebildeten Kragen (342) auf dessen dem Boden (7) zugewandten Unterseite (334). Auf diese Weise ist es notwendig, die elastischen Beine (332,333) in eine vom Ablaufstutzen (3) weggerichtete Richtung zu verbiegen, um sie von der Mutter (20) abheben zu können. Um diese Ablösung der Beine (332,333) vom Kragen (342) zu erleichtern, ist unterhalb des Kragens auf der Mutter (20) eine Lagerstelle (344) ausgebildet, auf der ein Drehring (345) um eine sich durch die Ablaufgarnitur erstreckende Mittelachse drehbar gelagert ist. Dieser Drehring besitzt eine asymetrische äußere Begrenzung (346). Aus dieser ragen in Richtung auf die Beine (332,333) Erhebungen (347) heraus, die mit ihrem von der Mittellinie am weitesten entfernten obersten Punkten (348) beim Drehen des Drehrings (345) um seine Mittelachse jeweils ein Bein (332,333) beaufschlagen und dieses aus den Aufnahmeschlizten (340) herausdrückt. In dieser herausgedrückten Lage der Beine (332,333) kann das Schwimmergehäuse (320) von der Mutter (20) abgehoben werden.In addition, the float housing (320) can also be compared to the Nut (20) must be adjusted, with which the drain connector (13) on the floor (7) of the housing (1) is attached. In this case the Nut (20) evenly distributed on its outer circumference (339) Receiving slots (340) in each of which one leg (332, 333) of the Float housing (320) is anchored. In this case, stretch the receiving slots (340) from the outer periphery (339) of the Nut (20) in the direction of the drain connector (13). The in the Underneath the receiving slots (340), engage the legs (332, 333) with an angled end (341) one formed on the nut (20) Collar (342) on its underside facing the floor (7) (334). In this way it is necessary to use the elastic Legs (332, 333) in a direction away from the drain connection (3) to bend in order to be able to lift it off the nut (20). To facilitate this detachment of the legs (332, 333) from the collar (342), is a bearing below the collar on the nut (20) (344) formed on which a rotating ring (345) around itself through the waste set extending center axis rotatably mounted is. This rotating ring has an asymmetrical outer boundary (346). From this rise in the direction of the legs (332,333) elevations (347) out with their farthest from the center line removed topmost points (348) when turning the rotating ring (345) act on one leg (332, 333) around its central axis and pushes this out of the receiving sleeves (340). In This pressed out position of the legs (332, 333) can do that Float housing (320) are lifted off the nut (20).
Beim Einsatz von Kollektormotoren für den Antrieb (43) könnte durch die Funkenbildung am Kollektor eine Explosion der Faulgase in der Abwasserleitung (27) und damit auch im Abwassersystem (28) entstehen. Um eine solche Explosion auf kleinsten Raum zu begrenzen, sind mindestens unterhalb des Antriebs (43) in Richtung auf das Abwassersystem (28) Sicherheitsgitter (219) vorgesehen, die bei einer Verpuffung entzündlicher Gase dafür sorgen, die die gleiche Funktion wie das Gitter einer Grubenlampe besitzen. Zweckmäßigerweise werden derartige Sicherheitsgitter (219) auch auf beiden Seiten des Antriebs (43) vorgesehen.When using collector motors for the drive (43) could an explosion of the digested gases due to the spark formation at the collector in the sewage pipe (27) and thus also in the sewage system (28) arise. In order to limit such an explosion to the smallest space, are at least below the drive (43) in the direction of the sewage system (28) security grille (219) provided the in the event of a deflagration of flammable gases, which have the same function as the grille of a miner's lamp. Conveniently such security grilles (219) are also on provided on both sides of the drive (43).
Der Vorteil dieser Ablaufgarnitur (3) besteht darin, daß sich auch ohne große Schwierigkeiten bei einer Absaugtoilette (349) Verwendung finden kann. Bei dieser steht eine den Geruchsverschluß ausbildende Restwassermenge (350) im unterem Teil des Toilettenbeckens (4). Diese Restwassermenge besitzt einen oberen Wasserpegel (351) dessen Höhe von einer Umlenkkante (352) vorgegeben ist, über die bei einer Spülung des Toilettenbeckens (4) eine in das Toilettenbecken (4) eintretende Wassermenge (353) ansteigen muß, damit sie in einen Absaugstutzen (354) gelangt, der sich unmittelbar an die Umlenkkante (352) anschließt. Dieser Umlenkstutzen (354) wird in Richtung des in die Abwasserleitung (27) abfließenden Wassers von einer Engstelle (355) begrenzt, hinter der sich ein Ausflußraum (356) in Richtung auf die Abwasserleitung (27) vergrößert. Auf Grund dieser Engstelle (355) wird das aus dem Toilettenbecken (4) ablaufende Wasser gestaut, so daß sich durch die eintretende Wassermenge (353) eine obere Kammer (357) vollständig füllt, in der die eintretende Wassermenge (353) oberhalb der Umlenkkante (352) in Richtung auf den Absaugstützen (354) umgelenkt wird. Aufgrund der hinter der Engstelle (355) auftretenden Volumenvergrößerung wird das Wasser aus dem Toilettenbecken (4) abgesaugt. The advantage of this waste set (3) is that it can also with little difficulty with a suction toilet (349) Can be used. This is the odor trap amount of residual water (350) in the lower part of the toilet bowl (4). This amount of residual water has an upper water level (351) whose height is predetermined by a deflection edge (352) is one in when flushing the toilet bowl (4) the amount of water (353) entering the toilet bowl (4) increases must, so that it gets into a suction nozzle (354), which immediately connects to the deflection edge (352). This deflection nozzle (354) in the direction of the flowing into the sewer (27) Water bounded by a narrow point (355), behind which an outflow space (356) towards the sewage pipe (27) enlarged. Because of this constriction (355), the Toilet basin (4) running water jammed so that through the entering amount of water (353) an upper chamber (357) completely fills, in which the entering amount of water (353) above the deflecting edge (352) is deflected in the direction of the suction supports (354) becomes. Due to the occurrence behind the constriction (355) Volume increase the water from the toilet bowl (4) aspirated.
In diese obere Kammer (357) mündet das Anschlußstück (31), das sich außermittig durch den Ablaufstutzen (13) erstreckt. Dabei ist in diesem Falle das Anschlußstück (31) gerade ausgebildet und tritt aus dem unterem Ende (25) des Ablaufstutzens (13) aus. Dabei verläuft das Anschlußstück (31) im wesentlichen parallel zu einer sich durch die Ablaufgarnitur (3) erstreckenden Mittellinie. Sie erstreckt sich durch einen Verteilerraum (358), in den die Spülflüssigkeit durch den Ablaufstutzen (13) eintritt und von dem aus sie gleichmäßig über das gesamte Toilettenbecken (4) entlang dessen Randes (359) verteilt wird.In this upper chamber (357) opens the connector (31), the extends eccentrically through the drain connector (13). It is in this case, the connector (31) just formed and emerges from the lower end (25) of the drain connector (13). Here runs the connector (31) substantially parallel to one extending through the drain set (3) center line. she extends through a distribution space (358) into which the rinsing liquid enters through the drain pipe (13) and from there they evenly over the entire toilet bowl (4) along it Randes (359) is distributed.
Das Anschlußstück (31) mündet mit seinem Anschlußende (35) in eine Absaugöffnung (361), die in einer Wandung (362) vorgesehen ist, durch die der Verteilerraum (358) von der oberen Kammer (357) abgetrennt wird. Dabei umbgibt die Anschlußmuffe (360) konzentisch die Absaugöffnung (361). Diese Absaugöffnung (361) liegt in gradliniger Richtung unterhalb des Anschlußstückes (31).The connector (31) opens with its connecting end (35) in one Suction opening (361), which is provided in a wall (362), through which the distribution space (358) is separated from the upper chamber (357) becomes. The connection sleeve (360) surrounds concentrically the suction opening (361). This suction opening (361) lies in a straight line Direction below the connector (31).
Die Anschlußmuffe (360) trägt einen elastischen Anschlußstutzen (363). Dieser Anschlußstutzen (363) kann als eine Doppelmuffe ausgebildet sein, die mit ihrem der Anschlußmuffe (360) zugewandten unterem Ende diese umgreift und mit ihrem entgegengesetzten oberem Ende das Anschlußende (35) des Anschlußstückes (31) aufnimmmt.The connection sleeve (360) carries an elastic connection piece (363). This connection piece (363) can be designed as a double sleeve be the one facing the connecting sleeve (360) lower end embraces this and with its opposite upper end End of the connecting end (35) of the connecting piece (31).
Diese Anordung der Absaugöffnung (361) besitzt einen wesentlichen Vorteil, der darin besteht, daß die Ablaufgarnitur (3) sehr leicht auf einer Absaugtoilette (349) installiert werden kann. Zu diesem Zweck wird zunächst das Anschlußstück (31) mit seinem Anschlußende (35) in die elastische Muffe (360) hineingeschoben, die auf die Absaugöffnung (361) aufgesetzt ist. Anschließend wird das Gehäuse (1) mit seiner Öffnung (15) über das Absaugrohr (29) gestülpt, das mit den Anschlußstück (31) verbunden ist. Daraufhin wird das Gehäuse (1) auf üblicher Weise mit nicht dargestellten Schrauben und Muttern auf den Toilettenbecken (4) befestigt. Nunmehr kann mit Hilfe der Mutter (20) der Ablaufstutzen (13) mit dem sich durch ihn erstreckenden Anschlußstück (31) am Gehäuseboden (7) befestigt werden. Damit ist die Lage des auf der Mutter (20) ausgebildeten Ventilsitzes (52) festgelegt. Bezüglich dieses Ventilssitzes (52) wird das an der Verlängerung (30) befestigte Ventilteil (53) ausgerichtet, indem die Verlängerung (30) über das Absaugrohr (29) geschoben wird.This arrangement of the suction opening (361) has an essential one Advantage, which is that the waste set (3) is very light can be installed on a suction toilet (349). To this Purpose is first the connector (31) with its connection end (35) pushed into the elastic sleeve (360), which on the Suction opening (361) is placed. Then the housing (1) with its opening (15) slipped over the suction pipe (29) is connected to the connector (31). Thereupon the housing (1) in the usual way with screws and not shown Nuts attached to the toilet bowl (4). Now with Help the mother (20) of the drain pipe (13) with which it extending connector (31) attached to the housing base (7) will. So that is the location of the trained on the mother (20) Valve seat (52) set. Regarding this valve seat (52) the valve part (53) attached to the extension (30) is aligned, by the extension (30) over the suction pipe (29) is pushed.
Aufgrund des in der oberen Kammer (357) auftretenden Unterdrucks wird der Wasserpegel im Sperrwasserbehälter (82) um eine Höhe (369) angehoben, die dem Wasserpegel das im Toilettenbecken (4) stehenden Geruchverschlusses entspricht, wenn das Wasser aus der oberen Kammer (357) durch die Engstelle (355) in Richtung auf die Abwasserleitung (27) abläuft. Aus diesem Grunde muß dafür gesorgt werden, daß das Sperrwasser nicht durch das Absaugrohr (29) in Richtung auf den Unterdruckerzeuger (42) und dessen Antrieb (43) abläuft. Zu diesem Zwecke ist das Absaugrohr (29) über den Sperrwasserbehälter (82) hinaus in Richtung auf den Deckel (9) des Gehäuses (1) mit seinem oberem Rand (364) so weit hochgezogen, daß eine sich auf Grund des Unterdrucks aufbauende Wassersäule (365) mit ihrem oberem Ende (366) unterhalb des oberen Randes (364) endet. Zu diesem Zwecke wird der Sperrwasserbehälter (82) in einem Bereich innerhalb des Gehäuses (1) angeordnet, der etwa in halber Höhe des vom Gehäuse (1) umschlossenen Innenraumes (2) liegt. Aufgrund dieser Anordnung des Sperrwasserbehälters (82) kann die Verjüngung (67) sehr lang bis zum Deckel (9) ausgebildet werden, so daß auf jeden Fall das obere Ende (366) der Wassersäule (365) unterhalb des oberen Randes (364) liegt. Darüber hinaus kann unterhalb der Glocke (63) und oberhalb eines im Sperrwasserbehälter (82) stehenden Pegels (97) des Sperrwassers (96) ein Ausgleichsraum (367) vorgesehen sein, der einen wesentlichen Teil des aus dem Sperrwasserbehälter (82) angesaugten Sperrwassers aufnehmen kann. Dieser Ausgleichsraum (367) ist in Richtung auf den Deckel (9) oberhalb der Umbörtelung (77) zwischen der Verjüngung (67) und dem Mantelteil (65) vorgesehen. Auf diese Weise wird verhindert, daß beim Spülen der Absaugtoilette (349) das Sperrwasser (96) in das Absaugrohr (29) eindringen kann.Due to the negative pressure occurring in the upper chamber (357) the water level in the sealing water tank (82) is increased by one level (369) raised to the water level in the toilet bowl (4) standing odor trap corresponds when the water from the upper chamber (357) through the constriction (355) towards the Waste water pipe (27) runs off. For this reason, care must be taken be that the sealing water is not in through the suction pipe (29) Direction to the vacuum generator (42) and its drive (43) expires. For this purpose, the suction pipe (29) is above the sealing water tank (82) towards the cover (9) of the housing (1) with its upper edge (364) pulled up so far that a water column building up due to the negative pressure (365) ends with its upper end (366) below the upper edge (364). For this purpose, the sealing water tank (82) in one Area arranged within the housing (1), which is approximately in half Height of the interior (2) enclosed by the housing (1). Because of this arrangement of the sealing water tank (82) can taper (67) are formed very long up to the lid (9), so that in any case the upper end (366) of the water column (365) below the upper edge (364). In addition, below the bell (63) and above one in the sealing water tank (82) standing level (97) of the sealing water (96) a compensation room (367) can be provided, which is a substantial part of the take up the sealing water drawn into the sealing water tank (82) can. This compensation space (367) is towards the cover (9) above the edging (77) between the taper (67) and the jacket part (65) provided. This prevents that when rinsing the suction toilet (349) the sealing water (96) in the suction pipe (29) can penetrate.
Auf Grund der steckbaren Ausbildung der Ablaufgarnitur (3) kann das Gehäuse (1) leicht auf dem Toilettenbecken (4) einer Absaugtoilette (349) befestigt werden. Sowohl die Befestigung des Spülventils als auch die Anordung der Verlängerung (30) kann vorgenommen werden, wenn bereits das Gehäuse (1) auf dem Toilettenbecken (4) befestigt ist. Due to the pluggable design of the waste set (3) the housing (1) easily on the toilet bowl (4) of a suction toilet (349) can be attached. Both the attachment of the flush valve and the extension (30) can also be arranged if the housing (1) is already on the toilet bowl (4) is attached.
Um auch bei einem eventuell undicht werden Spülwasserzulauf (115) zu vermeiden, daß das Spülwasser (48) unkontrolliert aus dem Innenraum (2) des Gehäuses beispielsweise unter dessen Deckel (9) austritt, ist dafür Sorge getragen, daß das Spülventil (49) geöffnet ist, wenn ein oberer Pegel des Spülwassers (48) im Innenraum (2) aufgrund eines unkontrollierten Zulaufes von Spülwasser (48) überschritten wird. Zu diesem Zwecke ist auf diesem oberstem Pegel des Spülwassers (48), der keinesfalls überschritten werden darf, ein Notschwimmer (368) installiert, der für eine Öffnung des Spülventils (49) sorgt, um gegebenenfalls weiterhin in den Innenraum (2) zulaufendes Spülwasser (48) durch das Spülventil (49) in das Toilettenbecken (4) abzuleiten, falls die Menge des zulaufenden Spülwassers (48) durch den Ringraum (94) in den Spalt (50) zwischen Verlängerung (30) und Absaugrohr (29) nicht ausreichend abgeleitet werden kann. Dieser Notschwimmer (368) wird zweckmäßiger Weise mit der Verlängerung (30) verbunden. Dabei hat sich eine Befestigung des Notschwimmers (368) auf der ringförmigen Außenwandung (88) des Sperrwasserbehälters (82) als zweckmäßig erwiesen. Dieser Notschwimmer (368) wird mit einer so großen Auftriebskraft ausgestattet, daß er in der Lage ist, den gesamten beweglichen Teil der Ablaufgarnitur (3) entgegen den auf dem Spülventil (49) lastenden Schließkräften zu öffnen.In order to prevent leaks in the rinsing water (115) to avoid that the rinse water (48) uncontrolled from the interior (2) of the housing, for example, under its cover (9) emerges, care is taken to ensure that the flushing valve (49) is open is when an upper level of the rinse water (48) in the interior (2) due to an uncontrolled inflow of rinsing water (48) is exceeded. For this purpose is at this top level the rinse water (48), which must never be exceeded, an emergency float (368) installed to open the purge valve (49) ensures to continue in the interior if necessary (2) incoming flushing water (48) through the flushing valve (49) into the Derive toilet bowl (4) if the amount of the incoming Flushing water (48) through the annular space (94) into the gap (50) between Extension (30) and suction pipe (29) are not drained sufficiently can be. This emergency swimmer (368) becomes more appropriate Way connected to the extension (30). There is an attachment of the emergency swimmer (368) on the annular outer wall (88) of the sealing water tank (82) has proven to be useful. This emergency float (368) has such a great buoyancy equipped that he is able to move the entire Part of the drain fitting (3) against that on the flush valve (49) open closing forces.
