Description

Die Erfindung betrifft einen Abwasserablauf mit Geruchsverschluss, insbesondere als Ablauf für Duschwannen, umfassend ein Gehäuse, bestehend aus einem Bodenteil, der mit einem horizontal austretenden Ablaufstutzen versehen ist, und aus einem Deckelteil mit einer oben liegenden Öffnung, einen in die Öffnung eingesetzten Einlassstutzen, der oberhalb eines einen Teilbereich des Bodenteils einnehmenden Sumpfteils endet, eine den Einlassstutzen umgebende Wand, bei der ein Teilbereich mit einer Überlaufkante versehen ist, eine sich an die Überlaufkante der Wand anschließende Siphonstrecke mit wenigstens einer Wasserstandskammer.The invention relates to a waste water drain with odor trap, in particular as a drain for shower trays, comprising a housing, consisting of a bottom part, which is provided with a horizontally exiting outlet nozzle, and a lid part with an overhead opening, an inserted into the opening inlet port, the above a part of the bottom part engaging sump part ends, a surrounding the inlet nozzle wall, in which a portion is provided with an overflow edge, a subsequent to the overflow edge of the wall Siphonstrecke with at least one water level chamber.

Ein Abwasserablauf der genannten Art ist dem Gebrauchsmuster DE 1 935 990 zu entnehmen. Hier ist ein Gehäuse vorgesehen, das wannenförmig gestaltet ist und das demnach relativ ausladend für die Siphonstrecke sein muss. Es handelt sich bei dem Abwasserablauf gemäß Stand der Technik um einen Waschtischgeruchsverschluss, der aus Gusseisen hergestellt ist. Die nach dem Einbau auftretenden Probleme, die die Wasserstandskammern betreffen, sind schon bei diesem Gebrauchsmuster gesehen worden. Zum einen ist ein Verstopfen des Abwasserablaufes mit Textilfasern, Haaren und dergleichen zu erwarten, so dass es sehr auf die Reinigungsmöglichkeiten ankommt. Auch ist gesehen worden, dass bei längerem Nichtgebrauch der Geruchsverschluss durch das Austrocknen der Wassermenge nicht mehr seinen Zweck erfüllt, gegen Gerüche abzudichten.A waste water drain of the type mentioned is the utility model DE 1 935 990 refer to. Here, a housing is provided, which is designed trough-shaped and therefore must be relatively expansive for the Siphonstrecke. The waste water drain according to the prior art is a washstand trap made of cast iron. The after-installation problems that affect the water level chambers have already been seen in this utility model. On the one hand, a clogging of the wastewater discharge with textile fibers, hair and the like is to be expected, so that it depends very much on the cleaning options. It has also been seen that with prolonged disuse the odor trap by dehydrating the amount of water no longer fulfills its purpose to seal against odors.

EP 1 798 352 A1 zeigt einen Ablauf für sanitäre Apparate mit einem im Wesentlichen topfförmigen Gehäuse und einem mittigen Einlaufkanal. Der Einlaufkanal geht an der Unterseite des Gehäuses in einen Aufstaubereich über, der den Einlaufkanal konzentrisch umgibt. Von dem Aufstaubereich gelangt das durch den Ablauf fließende Wasser schließlich in einen außen liegenden Abflusssammelkanal. Der Ablauf bildet nur eine Sperrwasserkammer aus, wodurch eine insgesamt relativ große Aufbauhöhe resultiert. EP 1 798 352 A1 shows a drain for sanitary appliances with a substantially cup-shaped housing and a central inlet channel. The inlet channel merges at the bottom of the housing in a Aufstaubereich concentrically surrounding the inlet channel. From the Aufstaubereich the water flowing through the drain finally passes into an external drain collection channel. The process forms only a sealed water chamber, resulting in a total of relatively large height.

Diese Druckschrift offenbart somit die Merkmale des Oberbegriffs von Anspruch 1 und wird als nächstkommender Stand der Technik betrachtet.This document thus discloses the features of the preamble of claim 1 and is considered to be the closest prior art.

DE 10 2006 058 259 A1 zeigt einen Flachsiphon für einen Waschtisch oder ein Spülbecken, bei dem der ebenfalls nur aus einer Sperrwasserkammer bestehende Geruchsverschluss innerhalb eines Rohrquerschnittes ausgebildet wird. Das durch eine Einlauföffnung eintretende Wasser wird mittels eines Umlenkbogens um 90° umgelenkt und einem Rohrkörper zugeleitet. Dabei erstreckt sich eine erste Trennwand von der oberen Wandung des Rohres abwärts bis kurz über die Mitte und eine zweite Trennwand vom Boden aus aufwärts ebenfalls bis kurz über die Mitte, so dass beide Trennwände, wie auch in EP 1 798 352 A1 beschrieben, einen Überlappungsbereich und insgesamt einen Geruchsverschluss ausbilden. Da sich die Sperrwasserkammer in dem einstückig ausgebildeten Rohrsegment hinter dem 90°-Bogen und hinter der sich an den 90°-Bogen anschließenden ersten Trennwand befindet, ist die Zugänglichkeit zu diesem Bereich, die beispielsweise für Reinigungsarbeiten erforderlich ist, ungenügend. DE 10 2006 058 259 A1 shows a siphon for a sink or a sink, in which the also consisting of a sealed water chamber odor trap is formed within a pipe cross-section. The entering through an inlet opening water is deflected by means of a Umlenkbogens by 90 ° and fed to a tubular body. In this case, a first partition extends from the upper wall of the tube down to just over the middle and a second partition from the bottom upwards also just above the middle, so that both partitions, as well as in EP 1 798 352 A1 described, form an overlap region and an overall odor trap. Since the sealed water chamber is in the integrally formed pipe segment behind the 90 ° bend and behind the adjoining the 90 ° bend first partition, the accessibility to this area, which is required for example for cleaning work, insufficient.

DE 20 2008 011 197 U1 zeigt einer Ablaufarmatur mit Geruchsverschluss mit einem ebenfalls im Wesentlichen topfförmigen Gehäuse und einem mittigen Einlaufkanal. Der Einlaufkanal wird durch ein Tauchrohr ausgebildet, welches an der Unterseite vom Gehäuseboden beabstandet ist, so dass das durch den Einlaufkanal eingeleitete Wasser umgelenkt und letztlich über eine Überlaufkante einem Ablaufstutzen zugeleitet wird. Dabei ist die die Geruchssperre ausbildenden Sperrwasserkammer radial um das Zentrum herum angeordnet. Auch diese Ablaufvorrichtung bildet lediglich eine Sperrwasserkammer aus. DE 20 2008 011 197 U1 shows a drain fitting with odor trap with a likewise substantially cup-shaped housing and a central inlet channel. The inlet channel is formed by a dip tube, which is spaced at the bottom of the housing bottom, so that the introduced through the inlet channel water is deflected and ultimately fed via an overflow edge of a drain pipe. In this case, the sealing water chamber forming the odor barrier is arranged radially around the center. This drainage device also forms only a sealed water chamber.

Die genannten Abläufe weisen jeweils nur eine Sperrwasserkammer auf. Diese Sperrwasserkammer wird jeweils dadurch realisiert, dass das durch die jeweilige Einlauföffnung in den Ablauf eintretende Wasser die untere Begrenzung einer ersten Sperrwand unterfließen muss, dann in die Sperrwasserkammer gelangt um anschließend über die Oberkante einer zweiten Sperrwand in das dahinter angeordnete Abfluss-System zu gelangen. Dabei ist die Unterkante der ersten Sperrwand grundsätzlich niedriger angeordnet als die Oberkante der zweiten Sperrwand, so dass das Wasser nicht vollständig abfließen kann, sondern vielmehr eine Geruchsperre ausbildet, die eine Weiterleitung der im Abwassersystem vorhandenen Gase zur Einlauföffnung des Abflusses verhindert. Wird dem Abfluss über einen längeren Zeitraum kein neues Wasser zugeleitet, senkt sich der Wasserstand in der Sperrwasserkammer durch Verdunstung ab. Sobald der Wasserspiegel die untere Begrenzungskante der ersten Sperrwand unterschreitet, verliert die Geruchssperre ihre Funktion und die Gase aus dem Abwassersystem können ungehindert zur Einlauföffnung des Abflusses und damit nach außen gelangen. Je niedriger die Aufbauhöhe eines Ablaufes insgesamt ausgebildet ist, desto geringer wird in aller Regel der Höhenabstand zwischen der Unterkante der ersten Sperrwand und der Oberkante der zweiten Sperrwand. Aus hydrostatischen Gründen ist bei Konstruktionen mit nur einer Sperrwasserkammer aber eine mindest Sperrwasserhöhe einzuhalten, welche eine Mindestbauhöhe des Ablaufes insgesamt bedeutet. Dieses um einerseits bei Druckschwankungen aus dem Abwasserleitungssystem nicht Gefahr zu laufen, dass Faulgase aus dem Leitungssystem in die Wohnräume gelangt und damit kleine Verdunstungsverluste nicht ein Aufheben der Sperrwirkung und ebenfalls Faulgaszuführung zu den Wohnräumen ermöglicht.The said processes each have only one sealed water chamber. This barrier water chamber is realized in each case by the fact that the entering through the respective inlet opening in the flow of water must underflow the lower boundary of a first barrier wall, then enters the sealed water chamber to then get over the top of a second barrier wall in the drainage system arranged behind it. In this case, the lower edge of the first barrier wall is generally arranged lower than the upper edge of the second barrier wall, so that the water can not drain off completely, but rather forms an odor barrier, which prevents a transfer of existing in the sewer system gases to the inlet opening of the drain. If no new water is fed to the drain over a longer period of time, the water level in the sealed water chamber will drop due to evaporation. Once the water level falls below the lower boundary edge of the first barrier wall, the odor barrier loses its function and the gases from the sewage system can freely to the inlet opening of the drain and thus after get outside. The lower the overall height of a drain is formed in total, the lower is usually the height difference between the lower edge of the first barrier wall and the upper edge of the second barrier wall. For hydrostatic reasons, in constructions with only one sealed water chamber, however, a minimum sealing water level must be maintained, which means a minimum overall height of the outlet. This, on the one hand in pressure fluctuations from the sewer system not to run the risk that digested gases from the piping system enters the living spaces and thus small evaporation losses does not allow a lifting of the barrier effect and also Faulgaszuführung to the living spaces.

Da in neuerer Zeit derartige Abwasserabläufe mit Geruchsverschluss direkt in plattenförmige Dusch-Bodenelemente aus Schaumkunststoff eingesetzt werden ist eine kompakte und flache Bauweise sehr wesentlich, um hier nur einen geringen Platzbedarf zu beanspruchen.Since in recent times such wastewater drains with odor trap are used directly in plate-shaped shower floor elements made of plastic foam is a compact and flat design very essential to claim only a small footprint here.

Es stellt sich daher die Aufgabe, einen kompakteren, in der Gesamtbauhöhe weiter reduzierten und trotz dieser Bauweise alle Aufgaben eines Geruchsverschlusses erfüllenden Abwasserablauf anzugeben.It is therefore an object to provide a more compact, in the overall height further reduced and despite this design all the tasks of an odor trap fulfilling wastewater discharge.

Diese Aufgabe wird bei einem Abwasserablauf mit Geruchsverschluss der eingangs genannten Art dadurch gelöst, dass

  • eine sich an die Überlaufkante der Wand anschließende Siphonstrecke wenigstens eine Wasserstandskammer umfasst,
  • die sich an die Überlaufkante anschließende Siphonstrecke beispielsweise in Form einer Rundstrecke ausgebildet ist, die den Sumpfteil in Form eines Teilkreises umschließt und am Ablaufstutzen endet.
This object is achieved in a waste water drain with odor trap of the type mentioned in that
  • a siphon path adjoining the overflow edge of the wall comprises at least one water level chamber,
  • formed at the overflow edge siphon, for example in the form of a circular route is that surrounds the sump part in the form of a partial circle and ends at the outlet nozzle.

Eine der Kunststoff-Verarbeitungstechnologie entgegenkommende und stabile Bauweise des Abwasserablaufes ergibt sich dann, wenn die Siphonstrecke beispielsweise als eine aus Erhöhungen und Mulden bestehende Rundstrecke ausgebildet ist, deren Elemente ausschließlich mit dem Bodenteil verbunden sind. Vorzugsweise sind die Erhöhungen und/oder Mulden als Faltungen des Bodenteils ausgebildet.One of the plastic processing technology responsive and stable construction of the wastewater flow is obtained when the siphon is formed, for example, as an existing elevations and troughs circuit whose elements are connected exclusively to the bottom part. Preferably, the elevations and / or depressions are formed as folds of the bottom part.

Es soll aber nicht ausgeschlossen werden, dass sowohl Bodenteil als auch Deckelteil zur Bildung von entsprechenden Wasserkammern eingesetzt werden. Hierbei bietet sich an, die Siphonstrecke aus stalaktitisch und stalagmitisch ragenden Querwänden zu bilden, von denen die stalaktitischen, d.h. hängenden, mit dem Deckelteil und die stalagmitischen, d.h. stehenden, Querwände mit dem Bodenteil verbunden ist.However, it should not be ruled out that both bottom part and lid part are used to form corresponding water chambers. In this case, it makes sense to form the siphon of stalactitic and stalagmite transverse walls, of which the stalactic, i. hanging, with the lid part and the stalagmite, i. standing, transverse walls is connected to the bottom part.

Vorteilhaft ist es, wenn die den Einlassstutzen umgebende Wand durch einen Kegelstutzen gebildet wird, welcher in die Sturzwand von oben eingeschoben ist, so dass die Unterkante des Kegelstutzens dichtend auf dem Boden sitzt und auf der oberen Kante des umlaufenden Randes des Kegelstutzens der Rand des Einlassstutzens liegt. Der Kegelstutzen weist einen tiefer gelegenen Durchtritt mit einer Fließkante auf.It is advantageous if the wall surrounding the inlet nozzle is formed by a conical socket which is inserted into the lintel from above, so that the lower edge of the conical socket sits sealingly on the floor and on the upper edge of the peripheral edge of the conical nozzle the edge of the inlet nozzle lies. The conical socket has a deeper passage with a flowing edge.

Die sich an die Überlaufkante anschließende Siphonstrecke ist dann in Form einer Rundstrecke ausgebildet, welche den Sumpfteil in Form eines Teilkreises umschließt am Ablaufstutzen endet.The adjoining the overflow edge Siphonstrecke is then designed in the form of a circular path, which surrounds the sump part in the form of a partial circle ends on the outlet pipe.

Wesentlich ist, dass die Überlaufkante nur einen begrenzten Teilkreis umfasst so dass das aus durch dem Einlassstutzen von einer ersten Wasserstandskammer in eine zweite Wasserstandskammer geleitete Abwasser die zweite Wasserstandskammer nur über die begrenzte Überlaufkante verlassen kann. Das Abwasser durchfließt den Durchtritt, wobei die Unterseite des Durchtritts eine Überlaufkante darstellt. Nach Durchfließen des Durchtritts gelangt alles Abwasser in die Siphonstrecke, welche rundum begrenzt ist und insofern eine rohrartige Leitstrecke ausbildet. Der Abwasserstrom fließt am Durchtritt in die rohrartige, einen Teilkreis um den Sumpfteil beschreibende Siphonstrecke ein, und gelangt am Ende der Siphonstrecke zum Ablaufstutzen. Die Auslaufkante des Einlassstutzens liegt tiefer als die Überlaufkante des Durchtritts. Das Wasser kann deshalb nur solange abfließen, wie nachströmendes Wasser dafür sorgt, dass der Wasserstand die Fließkante übersteigt. Sobald der Strom nachfließenden Wassers abreißt, stellt sich die Wasserstandshöhe in Fließkantenhöhe ein und bildet eine Geruchssperre aus.It is essential that the overflow edge comprises only a limited pitch circle so that the outgoing from the inlet port of a first water level chamber in a second water level chamber wastewater can leave the second water level chamber only on the limited overflow edge. The wastewater flows through the passage, wherein the bottom of the passage is an overflow edge. After passing through the passage, all wastewater enters the siphon section, which is completely bounded and thus forms a tubular guide section. The wastewater flow flows in at the passage in the tube-like siphon section describing a partial circle around the sump part, and reaches the outlet connection at the end of the siphon section. The outlet edge of the inlet nozzle is lower than the overflow edge of the passage. The water can therefore only drain as long as inflowing water ensures that the water level exceeds the flow edge. As soon as the stream of flowing water breaks off, the water level rises to the level of the edge of the river and forms an odor barrier.

Bei Ausbildung mit Erhöhungen und Mulden hat sich eine Siphonstrecke als optimal erwiesen, die drei Erhöhungen und zwei Mulden aufweist, so dass zwei Wasserkammern im Bereich der Siphonstrecke gebildet sind. Für einen entsprechenden Einsatzzweck oder -ort kann auch eine Siphonstrecke mit zwei Erhöhungen und einer Mulde eingesetzt werden.When formed with elevations and troughs, a siphon distance has been found to be optimal, which has three elevations and two wells, so that two water chambers are formed in the siphon range. For a suitable application or location, a siphon line with two elevations and a trough can also be used.

Wesentlich ist, die Teile des Abwasserablaufes zu Reinigungszwecken leicht voneinander trennen zu können. Grundsätzlich kann das Deckelteil vom Bodenteil abgehoben werden, ohne dass hierfür besondere Maßnahmen erforderlich sind. Für das Innere des Sumpfteils hat sich als vorteilhaft erwiesen, dass die Siphonstrecke zum Sumpfteil hin von dem vom Deckelteil ausgehenden und bis auf den Boden des Sumpfteils reichenden Kegelstutzen begrenzt ist, der am Beginn der Siphonstrecke einen Durchtritt mit Überlaufkante aufweist. Der konisch ausgebildete Kegelstutzen soll dabei sowohl im Betrieb sicher im Bodenteil gehalten werden können, während er zu Reinigungszwecken auch herausnehmbar ist. Um dieses zu ermöglichen, wird der Deckelteil des Gehäuses mit einer den Einlassstutzen in radialem Abstand umgebender Sturzwand verbunden. Die Sturzwand ist vorzugsweise mit dem Deckel des Gehäuses einstückig verbunden hergestellt. Sie weist an ihrer Innenseite vorzugsweise eine ebenfalls konisch ausgebildete Wand auf, so dass an ihrer Innenseite der Kegelstutzen getragen werden kann. Mit Hilfe von entsprechenden Rastelementen, die aus federndem Kunststoff hergestellt sein können, ist der Kegelstutzen mit der Sturzwand verrastet.It is essential to be able to easily separate the parts of the wastewater drain for cleaning purposes. In principle, the cover part can be lifted off the bottom part without the need for special measures. For the interior of the sump part has proved to be beneficial proved that the Siphonstrecke is limited to the bottom part of the starting from the lid part and reaching to the bottom of the sump portion conical socket, which has a passage with overflow edge at the beginning of the siphon. The cone-shaped conical socket is intended to be kept safe in the bottom part both during operation, while it is also removable for cleaning purposes. In order to make this possible, the cover part of the housing is connected to a crash wall surrounding the inlet connection at a radial distance. The lintel is preferably made integral with the lid of the housing. It preferably has on its inside a likewise conical wall, so that on its inside the conical socket can be worn. With the help of corresponding locking elements, which may be made of resilient plastic, the conical socket is locked to the lintel wall.

Der Kegelstutzen, der bis auf den Boden reicht, trägt an seiner umlaufenden Oberkante vorzugsweise den Einlaufstutzen, der in an sich bekannter Weise an seinem oberen Ende als kreisrunder, pilzkopfartiger Gefällekragen gestaltet ist, der zur Mitte hin in einem Auslauf übergeht.The conical socket, which extends to the ground, preferably carries at its peripheral upper edge of the inlet nozzle, which is designed in a conventional manner at its upper end as a circular, mushroom-like slope collars, which merges towards the center in an outlet.

Der Bodenteil mit der Siphonstrecke wird vorzugsweise einteilig als Metallgussteil, Kunststoff-Spritzgussteil oder Blasformteil ausgebildet. Der Deckelteil, der mit dem Bodenteil kompatibel ist, wird vorzugsweise aus Kunststoff in Form von Spritzgussteil oder Blasformteil hergestellt. Dieses gilt auch für die einzelnen Einsatzteile.

Figur 1 stellt eine Schnittdarstellung eines Abwasserablaufs 1 dar, der in ein plattenförmiges Dusch-Bodenelement 2 aus Schaumkunststoff eingesetzt ist, von dem nur ein kleiner Abschnitt gezeichnet ist. In das Dusch-Bodenelement 2 ist eine Bodenöffnung 2.1 eingebracht, die den Abwasserablauf aufnimmt. Im Einbauzustand überragt der Abwasserablauf 1 das Dusch-Bodenelement 2 um eine Höhe h, so dass die Höhe einer Fliesenauflage (nicht dargestellt), die auf das Dusch-Bodenelement 2 aufgeklebt ist, berücksichtigt werden kann. Das Duschbodenelement 2 wird vorzugsweise vor seinem Einbau in eine entsprechende Bodenöffnung 2.1 oder Vertiefung mit dem Abwasserablauf 1 gerüstet, wobei lediglich die Teile, die nach dem Einbau das Niveau des Duschbodenablaufs 2 nach oben überragen, üblicherweise nachgerüstet werden. Der Boden 9 des Abwasserablaufs 1 liegt bündig mit der offenen Unterseite des Dusch-Bodenelementes 2. FIG. 1 shows a sectional view of a waste water drain 1, which is inserted into a plate-shaped shower floor element 2 made of foam plastic, of which only a small portion is drawn. In the shower floor element 2, a bottom opening 2.1 is introduced, which receives the waste water drain. In the installed state of the waste water drain 1 dominates the shower base element 2 by a height h, so that the height of a tile support (not shown), which is glued to the shower base element 2, can be considered. The shower floor element 2 is preferably prepared prior to its installation in a corresponding bottom opening 2.1 or depression with the waste water drain 1, wherein only the parts which project beyond the level of the shower floor drain 2 after installation are usually retrofitted. The bottom 9 of the waste water drain 1 is flush with the open bottom of the shower base element. 2

Der Abwasserablauf 1 besitzt ein Gehäuse 3, das in Draufsicht etwa die Gestalt eines vollflächig ausgeführten Buchstabens D hat. An das Gehäuse 3 ist seitlich ein Ablaufstutzen 4 angeschlossen, der sich in ein Leitungsrohr (nicht dargestellt) fortsetzt. Das Gehäuse 3 besteht aus zwei übereinanderliegenden Teilen, nämlich aus einem Bodenteil 3.1 und einem Deckelteil 3.2. Der Deckelteil 3.2, der randbündig auf den Bodenteil 3.1 aufgesetzt ist, ist im Mittelbereich offen (Öffnung 5). Um die Öffnung 5 herum ist eine waagerecht liegende Krempe 3.3 als Abdeckung des Bodenteils 3.1 vorgesehen.The waste water drain 1 has a housing 3, which has approximately the shape of a full-surface running letter D in plan view. To the housing 3, a discharge nozzle 4 is connected laterally, which continues in a conduit (not shown). The housing 3 consists of two superposed parts, namely a bottom part 3.1 and a cover part 3.2. The cover part 3.2, which is flush mounted on the bottom part 3.1, is in the middle area open (opening 5). Around the opening 5 around a horizontal brim 3.3 is provided as a cover of the bottom part 3.1.

Entlang der Peripherie der Öffnung 5 verläuft nach unten ragend eine Sturzwand 6, die vorzugsweise einstückig mit dem Deckelteil 3.2 hergestellt ist. Die Sturzwand 6 bildet einen nach unten konvergierenden Stutzen, der bis in das Bodenteil 3.1 hineinragt. An wenigstens zwei gegenüberliegenden Positionen ragen vom Fuß der Sturzwand 6 ausgehend nach oben biegsame Rasthaken 8 nach innen und oben (vergl. Fig. 1), die einstückig aus dem Kunststoffmaterial der Sturzwand 6 hergestellt sind. Die Rasthaken 8 enden am oberen Ende in einer Rastnase 8.1, die nach innen zum Stutzenmittelpunkt, vorragen.Along the periphery of the opening 5 extends downwardly projecting a crash wall 6, which is preferably made in one piece with the cover part 3.2. The lintel 6 forms a downwardly converging nozzle, which projects into the bottom part 3.1. At at least two opposite positions protrude from the foot of the lintel 6, starting up flexible latching hooks 8 inwards and upwards (see. Fig. 1 ), which are made in one piece from the plastic material of the crash wall 6. The latching hooks 8 end at the upper end in a latching nose 8.1, which protrude inwards to the nozzle center point.

Der Bodenteil 3.1 des Gehäuses 3 umfasst in seinem Mittelbereich ein annähernd rundes Sumpfteil 7 mit einem Boden 7.1, der gleichzeitig einen Teil des Bodens 9 des Abwasserablaufs 1 bildet. In den Sumpfteil 7 hinein - bis zu dessen Boden 7.1 - ragt die Sturzwand 6 und bildet einen umlaufenden Abschluss des Sumpfteils 7. Dabei sind im oberen Bereich der Sturzwand 6, das heißt etwa in Höhe der Krempe 3.3 des Deckelteils, Fenster 6.1 eingelassen.The bottom part 3.1 of the housing 3 comprises in its central region an approximately round bottom part 7 with a bottom 7.1, which at the same time forms part of the bottom 9 of the waste water effluent 1. In the sump part 7 - up to the bottom 7.1 - projects the lintel wall 6 and forms a peripheral completion of the sump part 7. In the upper region of the lintel 6, that is approximately at the level of the brim 3.3 of the lid part, window 6.1 is inserted.

Als weiteres wesentliches Konstruktionsteil ist ein Kegelstutzen 10 in die Sturzwand 6 von oben eingeschoben, der nach oben und nach unten offen ist und im wesentlichen aus einer Wand besteht, die dieselbe Konizität hat wie die Sturzwand 6. Im Bereich der Position der Rasthaken 8 ist die Innenseite des Kegelstutzens 10 mit Rasttaschen 10.1 versehen, die sich beim Eindrücken des Kegelstutzens 10 über die Rastnasen 8.1 schieben, sodass diese schließlich über den oberen Rand der Rasttaschen 10.1 springen und den Kegelstutzen 10 gegen eine Verschiebung nach oben hindern. In dieser Position des Kegelstutzens 10 ruht dessen Unterkante 10.2 des Kegelstutzens 10 dichtend auf dem Boden 7.1.As a further essential construction part, a conical socket 10 is inserted into the lintel wall 6 from above, which is open upwards and downwards and consists essentially of a wall which has the same conicity as the lintel wall 6. In the region of the position of the latching hook 8 is the Inside the conical socket 10 provided with latching pockets 10.1, 10 slide over the locking lugs 8.1 when pressing the cone neck, so that they finally jump over the upper edge of the snap-in pockets 10.1 and prevent the conical socket 10 against displacement upwards. In this position of the conical socket 10 whose lower edge 10.2 of the conical socket 10 rests sealingly on the floor 7.1.

Auf der oberen Kante des umlaufenden Randes 10.3 des Kegelstutzens 10 liegt der Rand eines Einlassstutzens 12 und ist hier mit einem Dichtungsring 13 in einen Innensteg eines Halterings 14 geklemmt eingesetzt. Der Kegelstutzen 10 besitzt außerdem einen tiefer gelegten Durchtritt 16 mit einer Fließkante 16.1. Der Einlassstutzen 12 ist an seinem oberen Ende als kreisrunder, pilzkopfartiger Gefällekragen 12.1 gestaltet, der zur Mitte hin in einen Auslauf 12.2 übergeht. Nach oben ist durch einen Halterahmen 25 und ein aufgelegtes Rost 26 in an sich benannter Weise ein Abschluss hergestellt, in den das Abwasser abfließen kann.On the upper edge of the peripheral edge 10.3 of the conical socket 10, the edge of an inlet nozzle 12 and is here clamped with a sealing ring 13 inserted into an inner web of a retaining ring 14. The conical socket 10 also has a lowered passage 16 with a flow edge 16.1. The inlet nozzle 12 is designed at its upper end as a circular, mushroom-like slope collars 12.1, which merges into the middle towards an outlet 12.2. At the top, a conclusion is made by a support frame 25 and an on-hook grate 26 in a manner known per se, in which the wastewater can flow.

Der Auslauf 12.2 endet im Einbauzustand einige Millimeter oberhalb des Sumpfteil-Bodens 7.1. In einigem Abstand um die Wand des Auslaufs 12.2 herum verläuft die Innenseite des Kegelstutzens 10, so dass im Bereich des Sumpfes 7 zwei Wasserstandskammern W1 und W2 gebildet sind.The outlet 12.2 ends in the installed state a few millimeters above the bottom part bottom 7.1. At some distance around the wall of the outlet 12.2 around the inside of the cone neck 10 runs, so that in the area of the sump 7 two water level chambers W 1 and W 2 are formed.

Um einen längeren Stauweg für das durch den Einlassstutzen 12 einfließende Wasser zu erreichen, ist der Bodenteil 3.1 von einer umlaufenden, gekrümmten Siphonstrecke 15 umgeben, die sich unterhalb der Krempe 3.3 befindet (vgl. Fig. 4). Die Siphonstrecke 15 ist als eine Art runde Laufstrecke gestaltet. Sie verbindet den Überlauf-Durchtritt 16 am oberen Rand des Kegelstutzens 10, der den Sumpfteil 7 umgibt, mit dem Ablaufstutzen 4.In order to achieve a longer stowage path for the water flowing through the inlet pipe 12, the bottom part 3.1 is surrounded by a circumferential, curved siphon pipe 15 which is located below the brim 3.3 (cf. Fig. 4 ). The Siphonstrecke 15 is designed as a kind of round track. It connects the overflow passage 16 at the upper edge of the conical socket 10, which surrounds the sump part 7, with the discharge nozzle 4.

Die Oberflächen-Kontur der Siphonstrecke 15 ist aus Figur 4 zu erkennen. Das über die Fließkante 16.1 des Durchtritts 16 fließende Wasser gelangt zunächst auf eine Fläche 17 und fließt über das Gefälle 18 in die vertiefte erste Mulde 19. Dort bildet sich eine Wasserstandskammer W3.The surface contour of the siphon path 15 is off FIG. 4 to recognize. The water flowing over the flow edge 16. 1 of the passage 16 initially reaches a surface 17 and flows via the gradient 18 into the recessed first depression 19. There, a water level chamber W 3 forms .

Nach Überlauf der die Mulde 19 begrenzenden Erhöhung 20, die somit als Trennwand fungiert, gelangt das Abwasser in die zweite Mulde 21, wo sich ein Wasserstau und damit eine Wasserstandskammer W4 bildet. Nach Überwindung der weiteren Erhöhung 22 fließt das Wasser in den Ablaufstutzen 4, dem eine Sammelkammer 23 vorgeschaltet ist. Wie erkennbar, ist die Siphonstrecke 15 in Form einer Rundstrecke ausgebildet, die den Sumpfteil 7 in Form eines Teilkreises umfliest und am Ablaufstutzen 4 endet.After overflow of the recess 19 limiting increase 20, which thus acts as a partition, the wastewater enters the second well 21, where a water accumulation and thus a water level chamber W 4 forms. After overcoming the further increase 22, the water flows into the outlet pipe 4, a collecting chamber 23 is connected upstream. As can be seen, the siphon section 15 is designed in the form of a circular route, which surrounds the sump part 7 in the form of a partial circle and ends at the discharge nozzle 4.

Anstelle des Aufbaus mit zwei Mulden und drei Erhöhungen 22 kann auch eine Siphonstrecke mit einer Mulde und zwei Erhöhungen gestaltet werden; auch können drei oder mehr Mulden (Anzahl n) mit n + 1 Erhöhungen kombiniert werden.Instead of the construction with two troughs and three elevations 22, a siphon path with a trough and two elevations can also be designed; Also, three or more troughs (number n) can be combined with n + 1 elevations.

Im Prinzip ist es möglich, den Teilkreis um einen größeren Umlaufwinkel herumlaufen zu lassen, so dass möglicherweise eine weitere Wasserstandskammer gebildet werden kann. Allerdings muss ein Gleichgewicht zwischen Wasserdruck-Widerstand und Gefälle erreicht werden.In principle, it is possible to let the pitch run around a larger angle of rotation, so that possibly a further water level chamber can be formed. However, a balance between water pressure resistance and gradient must be achieved.

Wie erkennbar, sind die Erhöhungen und Mulden als Faltungen des Bodenteils gebildet und somit in üblicher Kunststoffverarbeitungstechnik, wie Spritzgießen und Blasgie-βen, zu erzielen. Der Bodenteil ist außerdem von einer umlaufenden, die Kontur eines D bildenden Außenwand 24 umgeben, die von der Ablaufstutzenöffnung durchbrochen wird.As can be seen, the elevations and depressions are formed as folds of the bottom part and thus in conventional plastics processing technology, such as injection molding and blowing βen to achieve. The bottom part is also surrounded by a peripheral, the contour of a D forming outer wall 24, which is broken by the downcomer opening.

Wie bereits beschrieben, baut sich auf der abgedichteten Außenwand 24 der Deckelteil 3.2 mit seinen weiteren Elementen auf.As already described, the lid part 3.2 with its further elements builds up on the sealed outer wall 24.

In Abwandlung von der dargestellten Siphonstrecke 15 kann auch eine Siphonstrecke aus stalaktisch oder stalagmitisch ragenden Querwänden gebildet sein, von denen die stalaktitische(n) mit dem Deckelteil und die stalagmitische(n) Querwände mit dem Bodenteil verbunden sind.In a modification of the illustrated siphon 15 also a siphon can be formed from stalactic or stalagmite transverse walls, of which the stalactic (n) with the lid part and the stalagmite (s) transverse walls are connected to the bottom part.

Die beschriebene Kombination aus Abwasserablauf und Geruchsverschluss ist aufgrund ihrer kompakten Bauweise vorteilhaft in die Masse eines Dusch-Bodenelementes 2 einzubetten und auch hieraus wieder im Falle einer Reparatur zu entnehmen, wobei vorzugsweise Einzelteile auch einzeln entnehmbar sind.The described combination of wastewater drainage and odor trap is due to its compact design advantageous to embed in the mass of a shower base element 2 and also to remove it again in the event of repair, with individual parts preferably also be removed individually.
