Abstract

The drainage has a housing (2), in which an inlet channel (5) and a discharge collecting channel (12) are formed. The inlet channel and the discharge collecting channel are separated from each other by a retention area (10) for forming a waste trap. A housing cover (6) is formed at the upper side of the housing, which covers a central area of the housing. The inlet channel extends between an outer wall (7) of the housing and a separating wall (8) arranged within the housing. An independent claim is also included for a sanitary tub with a tub body.

Description

Die Erfindung betrifft einen Ablauf, insbesondere für sanitäre Einrichtungen, mit einem Gehäuse, wobei innerhalb des Gehäuses ein Einlaufkanal und ein Abflusssammelkanal ausgebildet sind, die zur Bildung eines Siphons durch einen Aufstaubereich voneinander getrennt sind, wobei an der Oberseite des Gehäuses ein Gehäusedeckel vorgehen ist, der einen mittleren Bereich des Gehäuses abdeckt und der einen den Aufstaubereich mit dem Abflusssammelkanal verbindenden Überlaufabschnitt begrenzt und wobei sich der Einlaufkanal zwischen einer Außenwand des Gehäuses und einer innerhalb des Gehäuses angeordneten Trennwand erstreckt und wobei sich der Überlaufabschnitt in vertikaler Richtung über den oberen Rand des Einlaufkanals hinaus erstreckt. Der Ablauf ist insbesondere für Dusch-, Bade- oder Whirlpoolwannen vorgesehen. Der Ablauf kann darüber hinaus auch als Bodenablauf, beispielsweise in Sanitärräumen, eingesetzt werden.The invention relates to a drain, in particular for sanitary facilities, with a housing, wherein within the housing, an inlet channel and a drain collection channel are formed, which are separated from each other to form a siphon by a Aufstaubereich, wherein at the top of the housing, a housing cover proceed, which covers a central region of the housing and which defines an overflow section connecting the poppet region to the drain collection channel and wherein the inlet channel extends between an outer wall of the housing and a partition disposed within the housing, and wherein the overflow section extends vertically above the upper edge of the inlet channel extends beyond. The process is especially designed for shower, bath or spa baths. The process can also be used as a floor drain, for example in sanitary facilities.

Um gestiegenen Anforderungen an das Design sowie die Funktionalität bei Sanitärwannen gerecht zu werden, wird für solche sanitäre Einrichtungen eine möglichst geringe Bauhöhe angestrebt. So sind Duschwannen bekannt, die gegenüber einer angrenzenden Bodenfläche nur eine geringe Schwelle aufweisen oder vollständig in eine Bodenfläche integriert sind. Entsprechende Wannen weisen nicht nur durch eine besonders ansprechende, hochwertige Optik auf sondern führen auch zu einem deutlichen Komfortgewinn. Insbesondere sind derartige Wannen auch behindertengerecht, da keine hohe Schwelle überwunden werden muss. Die für solche Wannen vorgesehenen Abläufe müssen möglichst niedrig ausgeführt werden, damit diese nicht tief in eine Bodenfläche eingesetzt werden müssen. Gleichzeitig besteht gerade bei flachen Duschwannen das Problem, dass auch ein Überlaufen zu vermeiden ist, weshalb der Ablauf einen besonders hohen Durchfluss ermöglichen soll.In order to meet increased design requirements and functionality in sanitary tubs, the aim is to minimize the height of such sanitary facilities. Thus, shower trays are known which have only a small threshold in relation to an adjacent floor surface or are completely integrated in a floor surface. Corresponding tubs not only have a particularly appealing, high-quality look but also lead to a significant increase in comfort. In particular, such tubs are also handicapped accessible, since no high threshold must be overcome. The measures provided for such tubs processes must be performed as low as possible, so they do not have to be used deep in a floor area. At the same time there is the problem, especially with flat shower trays, that an overflow is also to be avoided, which is why the sequence should enable a particularly high flow rate.

Bestrebungen zu einem möglichst niedrigen Aufbau des Abflusses ergeben sich auch bei Abläufen für Bade- und Whirlpoolwannen, um den gestiegenen Designanforderungen gerecht zu werden. Schließlich ist auch bei einem Einsatz des Ablaufes als Bodenablauf eine niedrige Bauhöhe von Vorteil, da der Ablauf dann weniger tief in den Boden eingelassen werden muss.Efforts to minimize the build-up of runoff also arise in bath and spa tub processes to meet increased design requirements. Finally, even when using the drain as a floor drain, a low overall height is advantageous since the drain then has to be inserted less deeply into the floor.

Ein Ablauf mit den Merkmalen des Oberbegriffes des Patentanspruches 1 ist aus der WO 2008/135704 A1 bekannt. Ausgehend von dem Einlaufkanal zwischen der Außenwand des Gehäuses und einer innerhalb des Gehäuses angeordneten Trennwand gelangt das Wasser zunächst in den ringförmigen Aufstaubereich und dann bei einem Überströmen einer Anstauwand schließlich in den Abflusssammelkanal, der mittig innerhalb des ringförmigen Aufstaubereiches angeordnet ist. Das Wasser wird sodann nach unten geleitet und schließt über ein unterhalb des Ablaufes angeordnetes Anschlussstück ab. Nachteilig bei der bekannten Ausführung ist, dass das mittig angeschlossene Anschlussstück unterhalb des Ablaufes angeordnet ist, so dass sich bei einer vorgegebenen Stauhöhe eine noch relativ große Einbautiefe ergibt, obwohl das Anschlussstück zunächst ein flaches, in die Breite gezogenes Strömungsprofil aufweist.A sequence with the features of the preamble of claim 1 is known from WO 2008/135704 A1 known. Starting from the inlet channel between the outer wall of the housing and a partition wall disposed within the housing, the water first enters the annular Aufstaubereich and then at an overflow of an accumulation wall finally in the drain collection channel, which is arranged centrally within the annular Aufstaubereiches. The water is then directed downwards and closes off via a connection piece arranged below the drain. A disadvantage of the known design is that the centrally connected connector is located below the drain, so that at a given damming height results in a relatively large installation depth, although the connector initially has a flat, drawn in the width flow profile.

Aus der EP 1 574 629 A1 ist ein Ablauf für sanitäre Einrichtungen, insbesondere Duschwannen mit den Merkmalen des Oberbegriffes des Patentanspruches 1 bekannt, wobei ein Einlaufkanal, ein Aufstaubereich sowie ein Abflusssammelkanal in Reihe hintereinander angeordnet sind. Die EP 1 574 629 A1 offenbart damit die Form eines herkömmlichen Siphons, wobei durch die Anordnung der Abschnitte hintereinander die Strömungsquerschnitte und damit die Ablaufleistung begrenzt sind.From the EP 1 574 629 A1 is a drain for sanitary facilities, especially shower trays with the features of the preamble of claim 1 known, wherein an inlet channel, a Aufstaubereich and a drain collection channel are arranged in series one behind the other. The EP 1 574 629 A1 thus reveals the shape of a conventional siphon, wherein the flow cross sections and thus the drainage capacity are limited by the arrangement of the sections one behind the other.

Aus der DE 20 2008 011 010 U1 ist ein Ablauf für sanitäre Einrichtungen mit einem Gehäuse bekannt, wobei innerhalb des Gehäuses ein Einlaufkanal und ein Abflusssammelkanal ausgebildet sind, die zur Bildung eines Siphons durch einen Aufstaubereich voneinander getrennt sind. Diese Druckschrift beschäftigt sich mit dem Problem bei einer insgesamt kompakten Bauweise des Abflusses eine erhöhte Ablaufleistung zu erreichen, um insbesondere einen Einsatz an flachen Duschwannen zu ermöglichen. Um dies zu erreichen weist der Ablauf einen mittigen Einströmkanal auf, von dem das einströmende Wasser zunächst in einen innerhalb des Gehäuses außen liegenden Siphonkanal, der einen Aufstaubereich bildet, überführt wird. Zwischen dem Siphonkanal und dem Einströmkanal ist ein im Wesentlichen ringförmiger Abflusssammelkanal ausgebildet, von dem das Wasser durch eine Austrittsöffnung aus dem Gehäuse herausgeführt wird. Der Aufstaubereich und der Abflusssammelkanal, die jeweils im Wesentlichen ringförmig ausgebildet sind, weisen insgesamt vergleichsweise große Strömungsquerschnitte auf, da gemäß der DE 20 2008 011 010 U1 das einströmende Wasser zunächst nach außen geführt wird. Der beschriebene Ablauf zeichnet sich bei einer insgesamt relativ geringen Bauhöhe durch sehr gute Ablaufleistungen aus. Davon ausgehend besteht jedoch noch das Bedürfnis die Bauhöhe des Ablaufes weiter zu verringern.From the DE 20 2008 011 010 U1 For example, a sanitary appliance drainage system is known, wherein an inlet channel and a drainage collection channel are formed within the housing and are separated from one another by a jam area to form a siphon. This document deals with the problem with an overall compact design of the drain to achieve increased drainage performance, in particular to allow use on flat shower trays. In order to achieve this, the drain has a central inflow channel, from which the inflowing water is first transferred into a siphon channel, which forms an accumulation area, inside the housing. Between the siphon channel and the inflow channel, a substantially annular outflow collecting channel is formed, from which the water is led out of the housing through an outlet opening. The Aufstaubereich and the drainage collection channel, which are each formed substantially annular, have a total of comparatively large flow cross-sections, since according to the DE 20 2008 011 010 U1 the inflowing water is first led to the outside. The procedure described is characterized by a total of relatively low height by very good drainage performance. On this basis, there is still the need to further reduce the height of the process.

Aus den Druckschriften DE 201 01 787 U1 , DE 10 2005 013 942 A1 , EP 1 229 174 B1 und EP 1 798 352 A1 sind jeweils Abläufe bekannt, die ein im Wesentlichen topfförmiges Gehäuse mit einem mittigen Einlaufkanal aufweisen. 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 oder direkt in einen Abflussstutzen. Sowohl die Aufbauhöhe als auch die zu erreichende Durchflussmenge sind bei diesen Abläufen verbesserungsbedürftig.From the pamphlets DE 201 01 787 U1 . DE 10 2005 013 942 A1 . EP 1 229 174 B1 and EP 1 798 352 A1 each processes are known, which have a substantially cup-shaped housing with 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 or directly into a drain pipe. Both the construction height and the flow rate to be achieved in these processes need to be improved.

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, einen Ablauf mit den eingangs beschriebenen Merkmalen anzugeben, der eine besonders kompakte Anordnung an einer sanitären Einrichtung, insbesondere einer Duschwanne, ermöglicht.Against this background, the invention has for its object to provide a sequence with the features described above, which allows a particularly compact arrangement of a sanitary device, in particular a shower tray.

Die Aufgabe wird erfindungsgemäß durch einen Ablauf gemäß Patentanspruch 1 gelöst.The object is achieved by a process according to claim 1.

Erfindungsgemäß strömt das ablaufende Wasser nicht mittig, sondern am Rand des Abflusses ein. Der mittlere Bereich des Gehäuses ist vielmehr von einem Gehäusedeckel abgedeckt, der erfindungsgemäß die innerhalb des Gehäuse ausgebildeten Strömungswege begrenzt. Im Vergleich zu den aus dem Stand der Technik bekannten Ausführungen besteht somit die Möglichkeit die Strömungspfade bei gleichbleibender Siphonierungshöhe weiter nach oben zu versetzen, wodurch der Ablauf bei einer Anordnung an einer Sanitärwanne weniger nach unten vorsteht. Bei einer Sanitärwanne weist der Wannenkörper üblicherweise eine Vertiefung mit einer Ablauföffnung auf, an welcher der Ablauf angeordnet wird. Bei den aus dem Stand der Technik bekannten Abläufen sind die an einen Einströmkanal anschließenden Strömungswege vollständig unterhalb der Vertiefung sowie der darin ausgebildeten Ablauföffnung angeordnet. Die Erfindung offenbart in diesem Zusammenhang einen vorteilhaften Ansatz, wobei auch der Raum innerhalb der Vertiefung für die Ausbildung von Strömungswegen genutzt werden soll. So ist erfindungsgemäß vorgesehen, dass sich der Überlaufabschnitt in vertikaler Richtung über den oberen Rand des Einlaufkanals, d. h. den oberen Rand der Außenwand, hinaus erstreckt. Insbesondere kann vorgesehen sein, dass die Höhe des oberen Randes des Einlaufkanals etwa der Stauhöhe des Aufstaubereichs entspricht. Die Stauhöhe sowie die Höhe des oberen Randes beziehen sich dabei auf absolute Werte, die beispielsweise von der Unterseite des Gehäuses zu bestimmen sind. Als weitere für die Dimensionierung relevante Größe ist die Siphonierungshöhe zu beachten. Die Siphonierungshöhe gibt den Höhenunterschied an, durch welchen in dem Aufstaubereich der Einlaufkanal von dem Abflusssammelkanal getrennt ist. Die Siphonierungshöhe soll üblicherweise zumindest 25 mm, vorzugsweise zumindest 50 mm betragen, damit entsprechende Industrienormen erfüllt werden.According to the invention, the draining water does not flow in the middle, but at the edge of the drain. Rather, the middle region of the housing is covered by a housing cover which according to the invention limits the flow paths formed within the housing. Compared to the known from the prior art designs, it is therefore possible to move the flow paths at a constant Siphonierungshöhe further upwards, whereby the process in an arrangement on a sanitary tub projecting less down. In a sanitary tub, the tub body usually has a recess with a drain opening at which the drain is arranged. In the processes known from the prior art, the flow paths adjoining an inflow channel are arranged completely below the depression and the drain opening formed therein. The invention discloses in this context an advantageous approach, wherein the space within the recess for the formation of flow paths should be used. Thus, according to the invention, it is provided that the overflow section extends in the vertical direction beyond the upper edge of the inlet channel, ie the upper edge of the outer wall. In particular, it can be provided that the height of the upper edge of the inlet channel corresponds approximately to the damming height of the Aufstaubereichs. The damming height and the height of the upper edge refer to absolute values to be determined, for example, from the bottom of the housing. The siphoning height must be taken into account as a further size relevant to dimensioning. The Siphonierungshöhe indicates the height difference, by which in the Aufstaubereich the inlet channel is separated from the drain collection channel. The Siphonierungshöhe should usually be at least 25 mm, preferably at least 50 mm, so that corresponding industry standards are met.

Erfindungsgemäß schließt der Aufstaubereich über eine bodenseitige Verbindung an den Einlaufkanal an, wobei der Abflusssammelkanal zwischen dem Einlaufkanal und dem Aufstaubereich angeordnet ist. Im Rahmen einer solchen Ausgestaltung gelangt das einströmende Wasser zunächst im äußeren Bereich des Gehäuses in den randseitigen Einlaufkanal und wird dann über die bodenseitige Verbindung nach Innen zu dem Aufstaubereich geleitet, bevor das Wasser schließlich über den von der Unterseite des Gehäusedeckels begrenzten Überlaufabschnitt in den Abflusssammelkanal gelangt.According to the invention the Aufstaubereich connects via a bottom-side connection to the inlet channel, wherein the drainage collection channel is arranged between the inlet channel and the Aufstaubereich. In the context of such an embodiment, the incoming water first passes in the outer region of the housing in the peripheral inlet channel and is then passed over the bottom-side connection to the inside of the Aufstaubereich before the water eventually passes through the limited from the bottom of the housing cover overflow section in the drain collection channel ,

Um insgesamt möglichst große Strömungsquerschnitte zu erreichen, ist gemäß einer bevorzugten Ausgestaltung vorgesehen, dass der Aufstaubereich und der Abflusssammelkanal durch eine zylindrische Anstauwand voneinander getrennt sind.In order to achieve the largest possible flow cross-sections, it is provided according to a preferred embodiment that the Aufstaubereich and the drainage collection channel are separated by a cylindrical Anstauwand.

Um eine einfache Herstellung des Ablaufes sowie gute Strömungseigenschaften zu ermöglichen, werden einfache geometrische Strukturen bevorzugt. So kann bei einem zentral angeordneten Aufstaubereich der Abflusssammelkanal ringförmig um diesen angeordnet sein. Insbesondere können der Aufstaubereich und der Abflusssammelkanal bezüglich einer vertikalen Symmetrieachse im Wesentlichen rotationssymmetrisch ausgebildet sein. Abweichungen von der Rotationssymmetrie treten insoweit auf, dass noch ein Auslass für das durch den Ablauf fließende Wasser vorgesehen sein muss. So kann beispielsweise der Abflusssammelkanal in einen Abflussstutzen münden, der seitlich aus der Außenwand des Gehäuses herausgeführt ist. Um einen maximalen Durchfluss zu erreichen, kann der Abflussstutzen ausgehend von dem Abflusssammelkanal zunächst einen großen, beispielsweise rechteckigen Querschnitt aufweisen, der sich dann auf eine Kreisform verjungt, damit ein genormtes Rohranschlussstück befestigt werden kann. Abgesehen von dem seitlich herausgeführten Abschlussstutzen weist das Gehäuse bevorzugt eine im Wesentlichen zylindrische Außenform auf.In order to allow a simple production of the process and good flow properties, simple geometric structures are preferred. Thus, in a centrally arranged Aufstaubereich the drain collection channel can be arranged annularly around this. In particular, the Aufstaubereich and the drainage collection channel may be formed with respect to a vertical axis of symmetry substantially rotationally symmetrical. Deviations from the rotational symmetry occur to the extent that there is still an outlet for the through the drain flowing water must be provided. Thus, for example, the drainage collection channel can open into a drainage nozzle, which is led out laterally from the outer wall of the housing. In order to achieve a maximum flow, the discharge nozzle can initially have a large, for example rectangular, cross-section starting from the drainage collecting channel, which then narrows to a circular shape so that a standardized pipe connection piece can be fastened. Apart from the laterally led out end stub, the housing preferably has a substantially cylindrical outer shape.

Im Rahmen der Erfindung kann der Gehäusedeckel fest und dauerhaft mit dem Gehäuse verbunden sein. Vorzugsweise ist der Gehäusedeckel jedoch abnehmbar ausgeführt, um eine Reinigung und Entfernung von Verschmutzungen wie Haaren zu ermöglichen. Der Gehäusedeckel kann dazu beispielsweise klemmend oder durch eine Schraubverbindung fixiert sein. Schließlich ist es auch möglich den Gehäusedeckel an dem Gehäuse mit zusätzlichen Befestigungselementen zu fixieren. Besondere Vorteile ergeben sich im Rahmen der Erfindung auch dadurch, dass nach der Abnahme des Gehäusedeckels auch der Aufstaubereich und der Abflusssammelkanal leicht gereinigt werden können. Durch den Abflusssammelkanal sind auch der daran anschließende Abflussstutzen und ein Abflussrohr erreichbar, so dass bei einer Verstopfung eine Rohrreinigungsspirale, der Schlauch eines Hochdruckreinigungsgerätes oder dergleichen eingeführt werden kann. Zur Vermeidung der Strömungskanten weist der Gehäusedeckel an seiner den Überlaufabschnitt begrenzenden Unterseite eine gekrümmte Form auf.In the context of the invention, the housing cover can be firmly and permanently connected to the housing. Preferably, however, the housing cover is designed to be removable, to allow cleaning and removal of dirt such as hair. The housing cover can be fixed for example by clamping or by a screw connection. Finally, it is also possible to fix the housing cover to the housing with additional fasteners. Particular advantages also arise in the context of the invention in that after the removal of the housing cover and the Aufstaubereich and the drainage collection channel can be easily cleaned. Through the drain collection channel and the adjoining outflow nozzle and a drain pipe can be reached, so that when a blockage pipe cleaning spiral, the hose of a high-pressure cleaning device or the like can be introduced. To avoid the flow edges, the housing cover has a curved shape on its underside defining the underside.

Im Rahmen der Erfindung kann der Gehäusedeckel im montierten Zustand des Ablaufes sichtbar angeordnet sein. Um ein besonders hochwertiges Erscheinungsbild zu erreichen, ist gemäß einer bevorzugten Ausgestaltung der Erfindung aber ein zusätzlicher Dekordeckel vorgesehen, der auf das Gehäuse und den Gehäusedeckel aufgesetzt ist. Insbesondere besteht das Bedürfnis die im montierten Zustand zugänglichen Bereiche des Ablaufes mit einer hochwertigen und widerstandsfähigen Oberfläche zu versehen. Insbesondere bei Sanitärwannen aus Stahl-Email kann dies erreicht werden, wenn der Dekordeckel aus dem gleichen Material besteht. Zusätzlich ergibt sich so eine optimale Integration des Ablaufes in das gesamte Erscheinungsbild der Sanitärwanne. Um den Dekordeckel auf dem Gehäuse zu halten, kann ein formstabiler Träger vorgesehen werden, der aus Kunststoff, beispielsweise ABS, besteht. Der Dekordeckel und der Träger können beispielsweise durch eine Verklebung miteinander verbunden werden.In the context of the invention, the housing cover can be arranged visible in the assembled state of the sequence. In order to achieve a particularly high-quality appearance, however, an additional decorative cover is provided according to a preferred embodiment of the invention, which on the housing and the housing cover is placed. In particular, there is a need to provide the accessible in the assembled state areas of the process with a high-quality and durable surface. In particular, in sanitary baths made of steel enamel, this can be achieved if the decorative cover is made of the same material. In addition, this results in an optimal integration of the process into the overall appearance of the sanitary tub. In order to hold the decorative cover on the housing, a dimensionally stable support can be provided, which consists of plastic, for example ABS. The decorative cover and the carrier can be connected to each other, for example by gluing.

Um eine möglichst einfache und kostengünstige Herstellung des Ablaufs zu ermöglichen, ist dieser gemäß einer bevorzugten Ausgestaltung der Erfindung aus verschiedenen Teilen, insbesondere Kunststoffformteilen zusammengesetzt. So ist es möglich, das Gehäuse an seiner Unterseite durch einen separat gefertigten Gehäuseboden zu verschließen, der bei einer Fertigung aus einem thermoplastischen Kunststoff mit der Außenwand verschweißt oder alternativ verklebt werden kann. Die Befestigung des Ablaufs an einer Ablauföffnung einer Sanitärwanne erfolgt üblicherweise mit einem Spannring, wobei zwischen der Sanitärwanne und dem Spannring einerseits sowie der Sanitärwanne und einem Auflageflansch des Gehäuses andererseits eine Abdichtung vorzusehen ist, wozu beispielsweise eine ringförmige Konturdichtung geeignet ist.In order to enable the simplest possible and cost-effective production of the process, this is composed according to a preferred embodiment of the invention of various parts, in particular plastic moldings. Thus, it is possible to close the housing on its underside by a separately manufactured housing bottom, which can be welded or alternatively glued to the outer wall in a production of a thermoplastic material. The attachment of the drain to a drain opening of a sanitary tub is usually carried out with a clamping ring, between the sanitary tub and the clamping ring on the one hand and the sanitary tub and a support flange of the housing on the other hand, a seal is provided, including, for example, an annular contour seal is suitable.

Gegenstand der Erfindung ist auch eine Sanitärwanne mit einem Wannenkörper, der an einer Vertiefung eine Ablauföffnung aufweist, wobei an der Ablauföffnung der zuvor beschriebene Ablauf angeordnet ist. Damit der Ablauf bei einer Benutzung der Sanitärwanne nicht als störend empfunden wird und sich optimal in das gesamte optische Erscheinungsbild einpasst, ist die Oberseite des Abflusses bevorzugt etwa flächenbündig mit einem an die Vertiefung anschließenden ebenen Bereich des Wannenkörpers. Die Vertiefung springt dadurch üblicherweise um 15 mm bis 40 mm zurück. Erfindungsgemäß erstreckt sich ein Teil der Strömungskanäle ausgehend von der Ablauföffnung in diese Vertiefung hinein, wodurch der unterseitige Überstand des Ablaufs reduziert wird. Selbst bei einer Siphonierungshöhe von 50 mm ist es dabei im Rahmen der Erfindung möglich, dass der Ablauf ausgehend von dem unteren Rand der Vertiefung weniger als 70 mm, vorzugsweise weniger als 60 mm, nach unten vorsteht. Wie zuvor erläutert, weist das Gehäuse vorzugsweise eine im Wesentlichen zylinderförmige, das heißt kreiszylinderförmige Außenkontur auf. Durch die Anordnung eines zusätzlichen Dekordeckels ist dabei eine nahezu beliebige Anpassung an eine andersartig geformte Vertiefung, beispielsweise eine quadratische Vertiefung, möglich.The subject matter of the invention is also a sanitary tub with a tub body which has a drain opening at a depression, wherein the drain described above is arranged at the drain opening. Thus, the process is not distracting when using the sanitary tub and optimally fits into the overall visual appearance, the top of the drain is preferably approximately flush with a subsequent to the depression level area of the tub body. The recess usually jumps back by 15 mm to 40 mm. According to the invention, a part of the flow channels extending from the drain opening into this recess, whereby the underside projection of the process is reduced. Even with a siphonation height of 50 mm, it is possible within the scope of the invention for the outlet to protrude downwards from the lower edge of the depression to less than 70 mm, preferably less than 60 mm. As explained above, the housing preferably has a substantially cylindrical, that is circular-cylindrical outer contour. The arrangement of an additional decorative cover is an almost arbitrary adaptation to a differently shaped recess, such as a square recess, possible.

Die Fig. 1a zeigt in einem Ausschnitt einen Ablauf, der in eine Vertiefung 1 eines Wannenkörpers 2 einer Sanitärwanne eingesetzt ist. Im montierten Zustand des Ablaufs ist an der Oberseite der Sanitärwanne lediglich ein Dekordeckel 3 sichtbar, der flächenbündig mit einem an die Vertiefung 1 anschließenden ebenen Bereich des Wannenkörpers 2 der Sanitärwanne ist und wie der Wannenkörper 2 aus Stahl-Email besteht. Zwischen dem Dekordeckel 3 und dem Rand der Vertiefung 2 ist ein um den Umfang umlaufender Schlitz gebildet, durch welchen Wasser zu einem Gehäuse 4 des Ablaufs gelangen kann.The Fig. 1a shows in a section of a sequence which is inserted into a recess 1 of a tub body 2 of a sanitary tub. In the assembled state of the process, only a decorative cover 3 is visible on the top of the sanitary tub, which is flush with a subsequent to the recess 1 flat portion of the tub body 2 of the sanitary tub and how the tub body 2 made of steel enamel. Between the decorative cover 3 and the edge of the recess 2, a circumferential slot around the circumference is formed, through which water can reach a housing 4 of the drain.

Gemäß der Fig. 1b ist zu erkennen, dass abfließendes Wasser in einem radial außen liegenden Bereich des Gehäuses 4 in einen Einlaufkanal 5 gelangt, der sich zumindest um einen Teil des Umfangs des in seiner Außenkontur kreiszylindrischen Gehäuses 4 erstreckt. Zu erkennen ist des Weiteren, dass an der Oberseite des Gehäuses 4 ein Gehäusedeckel 6 aufgesetzt ist, der einen mittleren Bereich des Gehäuses 6 abdeckt, wobei sich der mittlere Bereich des Gehäuses 4 mit dem an seiner Oberseite angeordneten Gehäusedeckel 6 in vertikaler Richtung über den oberen Rand des Einlaufkanals 5, also den Boden der Vertiefung 1, in den Bereich der Vertiefung 1 hinein erstreckt.According to the Fig. 1b It can be seen that outflowing water in a radially outer region of the housing 4 enters an inlet channel 5, which extends at least around a part of the circumference of the circular cylindrical housing 4 in its outer contour. It can also be seen that on the upper side of the housing 4, a housing cover 6 is placed, which covers a central region of the housing 6, wherein the central region of the housing 4 with the arranged on its upper side housing cover 6 in the vertical direction over the upper Edge of the inlet channel 5, so the bottom of the recess 1, in the region of the recess 1 extends into it.

Weitere Details des erfindungsgemäßen Ablaufs sind den Schnittdarstellungen der Fig. 2 und Fig. 3 zu entnehmen. So erstreckt sich der Einlaufkanal 5 ausgehend von seinem oberen Rand zwischen einer Außenwand 7 des Gehäuses 4 und einer innerhalb des Gehäuses 4 angeordneten Trennwand 8. Einströmendes Wasser gelangt von dem Einlaufkanal 5 über eine bodenseitige Verbindung 9 zu einem mittigen Aufstaubereich 10, der von einer kreiszylindrischen Anstauwand 11 radial begrenzt und durch diese von einem umlaufenden Abflusssammelkanal 12 getrennt ist. Bei nachströmendem Wasser wird der einen Siphon bildende Aufstaubereich 10 am oberen Ende der Anstauwand 11 überspült, so dass dort das Wasser über einen den Abflusssammelkanal 12 mit dem Aufstaubereich 10 verbindenden Überlaufabschnitt 13 abfließen kann.Further details of the process according to the invention are the sectional views of Fig. 2 and Fig. 3 refer to. Thus, the inlet channel 5 extends from its upper edge between an outer wall 7 of the housing 4 and disposed within the housing 4 partition 8. inflowing water passes from the inlet channel 5 via a bottom connection 9 to a central Aufstaubereich 10, of a circular cylindrical Anstauwand 11 radially bounded and separated by this from a circulating drain collection channel 12. In the case of inflowing water, the siphon-forming accumulation area 10 becomes at the upper end of the accumulation wall 11 flushed over, so that there the water can flow via a drain collecting channel 12 connecting with the Aufstaubereich 10 overflow section 13.

Wenn kein weiteres Wasser nachströmt, definiert der obere Rand der Anstauwand 11 die Stauhöhe innerhalb des Ablaufs.If no additional water flows in, the upper edge of the accumulation wall 11 defines the accumulation level within the drain.

Erfindungswesentlich ist insbesondere, dass sich der mittlere Bereich des Gehäuses 4, der oberseitig von dem Gehäusedeckel 6 abgedeckt ist, bis in die Vertiefung 1 hinein erstreckt, wobei der Gehäusedeckel 6 den Überlaufabschnitt 13 nach oben hin begrenzt. Da sich die an den Einlaufkanal 5 innerhalb des Gehäuses anschließenden Strömungswege bis in die Vertiefung 1 hinein erstrecken, steht der gesamte Ablauf nach unten hin nur vergleichsweise wenig von dem Wannenkörper 2 ab. So kann in dem dargestellten Ausführungsbeispiel bei einer Siphonierungshöhe hS von 50 mm und einem Zurückspringen hT der Vertiefung 1 gegenüber den angrenzenden Bereichen des Wannenkörpers von 20 mm erreicht werden, dass der gesamte Ablauf nach unten hin lediglich knapp 60 mm von der Vertiefung 1 vorsteht. Die Höhe des oberen Randes des Einlaufkanals entspricht dabei etwa der Stauhöhe des Aufstaubereichs.It is particularly important to the invention that the middle region of the housing 4, which is covered on the top side by the housing cover 6, extends into the depression 1, with the housing cover 6 delimiting the overflow section 13 at the top. Since the flow paths adjoining the inlet channel 5 within the housing extend into the depression 1, the entire outlet is only comparatively slightly remote from the bathtub body 2 at the bottom. Thus, in the illustrated embodiment, with a siphoning height h S of 50 mm and a spring back h T of the depression 1 with respect to the adjoining regions of the trough body of 20 mm, it can be achieved that the entire process projects downwards from the recess 1 by just under 60 mm , The height of the upper edge of the inlet channel corresponds approximately to the damming height of the Aufstaubereichs.

Den Schnittdarstellungen der Fig. 2 und Fig. 3 ist des Weiteren zu entnehmen, dass die Befestigung des Gehäuses 4 an dem Wannenkörper 2 der Sanitärwanne mittels eines Spannrings 14 erfolgt, wobei zur Abdichtung und zum Schutz gegen übermäßige mechanische Belastungen eine Konturdichtung 15 zwischengelegt ist. Schließlich ist auch zu erkennen, dass der aus Stahl-Email gebildete Dekordeckel 3 vergleichsweise dünn ausgeführt ist und mittels eines formstabilen Trägers 16 aus dem Kunststoff auf dem Gehäuse 4 gehalten istThe sectional views of the Fig. 2 and Fig. 3 Furthermore, it can be seen that the attachment of the housing 4 takes place on the tub body 2 of the sanitary tub by means of a clamping ring 14, wherein for sealing and to protect against excessive mechanical stress, a contour seal 15 is interposed. Finally, it can also be seen that the decorative cover 3 formed from steel enamel is made comparatively thin and is held on the housing 4 by means of a dimensionally stable support 16 made of the plastic

Einer vergleichenden Betrachtung der Fig. 1b, 2 und 4 ist zu entnehmen, dass das Gehäuse 4 eine im Wesentlichen kreiszylindrische Außenkontur aufweist, wobei das Gehäuse 4 an der Unterseite durch einen auf die Außenwand 7 aufgesetzten Gehäuseboden 17 verschlossen ist. Die Ausbildung eines separaten Gehäusebodens 17, der mit der Außenwand 7 zu verkleben oder zu verschweißen ist, ermöglicht eine kostengünstige und einfache Fertigung der verschiedenen Kunststoffteile.A comparative consideration of Fig. 1b . 2 and 4 It can be seen that the housing 4 has a substantially circular cylindrical outer contour, wherein the housing 4 is closed at the bottom by a mounted on the outer wall 7 housing bottom 17. The formation of a separate housing bottom 17, which is to be glued or welded to the outer wall 7, allows a cost-effective and simple production of the various plastic parts.

Um den Ablauf leichter reinigen zu können, sind der Träger 16 mit dem darauf aufgeklebten Dekordeckel 3 und der Gehäusedeckel 6 leicht lösbar auf dem Gehäuse 4 angeordnet. Neben einer klemmenden Fixierung kann dazu auch eine Schraubverbindung vorgesehen sein. Nach der Abnahme von Dekordeckel 3 und Gehäusedeckel 6 können der Aufstaubereich 10 und der Abflusssammelkanal 12 leicht gereinigt und von Verschmutzungen wie Haare oder anderen Ablagerungen gereinigt werden.In order to be able to more easily clean the drain, the support 16 with the decorative cover 3 glued thereon and the housing cover 6 are arranged in an easily detachable manner on the housing 4. In addition to a clamping fixation can also be provided a screw connection. After removal of the decorative cover 3 and housing cover 6, the Aufstaubereich 10 and the drain collection channel 12 can be easily cleaned and cleaned of dirt such as hair or other deposits.

Der ringförmig um den Aufstaubereich 10 angeordnete Abflusssammelkanal 12 mündet in einen Abflussstutzen 18, der seitlich aus der Außenwand 7 des Gehäuses 4 herausgeführt ist. Um trotz der geringen Höhe einen großen Durchfluss zu erreichen, weist der Abflussstutzen einen breiten, rechteckigen Querschnitt auf. Unmittelbar an der Außenwand 7 des Gehäuses schließt ein Reduzierstück 19 an, welches den rechteckigen Querschnitt des Abflussstutzens 18 in einen runden Querschnitt überführt, so dass die Verbindung mit einem genormten Rohranschluss ermöglicht wird. Abgesehen von der Überleitung in den Abflussstutzen 18 ist der Abflusssammelkanal 12 wie auch der Aufstaubereich 10 und der Gehäusedeckel 6 im Wesentlichen rotationssymmetrisch ausgebildet. Auch der Abflussstutzen 18, das Redzierstück 19 und ein daran anschließendes Abflussrohr sind zur Reinigung beispielsweise mit einer Rohrreinigungsspirale zugänglich, wenn der Dekordeckel 3 und der Gehäusedeckel 6 abgenommen sind.The drain collecting channel 12, which is arranged annularly around the storage area 10, opens into a discharge connection 18, which is led out laterally out of the outer wall 7 of the housing 4. In order to achieve a large flow despite the low height, the outlet nozzle has a wide, rectangular cross-section. Immediately on the outer wall 7 of the housing includes a reducer 19, which converts the rectangular cross-section of the discharge nozzle 18 in a round cross section, so that the connection is made possible with a standardized pipe connection. Apart from the transfer into the outlet connection 18, the drainage collection channel 12, as well as the storage area 10 and the housing cover 6, are essentially rotationally symmetrical. Also, the drain port 18, the Redzierstück 19 and an adjoining drain pipe are accessible for cleaning, for example with a pipe cleaning spiral when the decorative cover 3 and the housing cover 6 are removed.

Fig. 5 zeigt exemplarisch eine flache Duschwanne, die mit dem erfindungsgemäßen Ablauf versehen ist. Fig. 5 shows an example of a flat shower tray, which is provided with the process according to the invention.
