Description

Die Erfindung betrifft einenUnterputzsifon mit einem eine Einlauföffnung und eine Ausströmöffnung aufweisenden Gehäuse und einem ins Gehäuse einsetzbaren L-förmig ausgebildeten Tauchrohr, wobei ein etwa horizontaler Einlauf-Rohrteil des Tauchrohres von der an einer Seitenwand des Gehäuses angeordneten Einlauföffnung in einen etwa vertikal angeordneten Tauch-Rohrteil des Tauchrohres mündet, der Tauch-Rohrteil in einen Steig-Rohrteil mündet und dieser mit einem Überlauf-Rand in einen abwärts führenden Kanal des Gehäuses übergeht, der über die Ausströmffönung in einen Ablaufkanal mündet, und wobei der Einlauf-Rohrteil leitungsgemäß an ein Ableitungsrohr, wie an ein Waschtisch-Ableitungsrohr, dichtend anschließbar istThe invention relates to a concealed siphon with one inlet opening and one Outflow opening housing and an L-shaped insert into the housing trained dip tube, with an approximately horizontal inlet pipe part of the dip tube from the inlet opening arranged on a side wall of the housing into an approximately vertical arranged dip tube part of the dip tube opens, the dip tube part in a riser tube part flows and this with an overflow edge in a downward channel of the Housing merges, which opens into a discharge channel via the outflow opening, and wherein the Inlet pipe part in line with a drain pipe, such as a sink drain pipe, is sealingly connectable

Ein dergleiches, gattungsgemäßes Unterputzsifon ist aus der DE-C - 34 47 098 bekannt. Bei diesem Unterputzsifon endet das Tauchrohr im Abstand oberhalb des Bodens des Gehäuses und es erstreckt sich vom Boden des Gehäuses eine Stauwand nach oben, um einen der Geruchssperre dienenden Wassersack zu bilden. Zwischen der Stauwand und einer Gehäuseseitenwand ist weiters ein abwärts führender Ablaufkanal des Unterputzsifons gebildet, der zur Ausströmöffnung des Gehäuses führt.A similar, generic concealed siphon is known from DE-C - 34 47 098. This ends with this concealed siphon Dip tube spaced above the bottom of the case and it extends from the bottom of the housing up a storage wall in order to close a water bag that serves to block the odor form. Between the storage wall and a housing side wall there is also a downward leading one Drain channel of the concealed siphon is formed, which leads to the outflow opening of the housing.

Nachteilig ist bei dieser Konstruktion, daß eine Reinigung des Sifons nur umständlich durchführbar ist. Zu diesem Zweck ist das Tauchrohr zu entfernen, wodurch dann der Wassersack zwar besser zugänglich ist, jedoch ist es nur schwierig, hieraus Fremdkörper zu entfernen. Weiters ist es nur sehr schwer möglich, den Ablaufkanal durchzuputzen, falls dieser verstopft ist, da eine Zugänglichkeit zu diesem nur über den oberen Rand der Stauwand möglich ist. Das Einführen einer Putzfeder oder ähnlicher Geräte gestaltet sich hierbei kompliziert und infolge einer starken Verformung der Putzfeder kraftaufwendig, soferne es überhaupt möglich ist. Es kann sich die Notwendigkeit ergeben, den Unterputzsifon aus der Mauer herauszustemmen.The disadvantage of this construction is that cleaning the siphon is only laborious is feasible. For this purpose, the immersion tube must be removed, which then causes the Although the water bag is more accessible, it is difficult to remove foreign bodies from it remove. Furthermore, it is very difficult to clean the drain channel if it is is blocked because access to it is only possible via the upper edge of the dam wall is possible. The insertion of a cleaning pen or similar devices is designed here complicated and due to a strong deformation of the cleaning feather, if it is is even possible. There may be a need to remove the concealed siphon from the To pry out the wall.

Die Erfindung bezweckt die Vermeidung dieser Nachteile und Schwierigkeiten und stellt sich die Aufgabe, einen Unterputzsifon der eingangs beschriebenen Art zu schaffen, der in einfacher Weise gereinigt werden kann. Insbesondere soll es auch möglich sein, den Ablaufkanal mühelos und ohne einen Ausbau des Unterputzsifons zu erfordern, durchzuputzen, beispielsweise eine Putzfeder in diesen einzuführen. Hierbei sollen starke Verformungen der Putzfeder vermieden werden. The invention aims at avoiding these disadvantages and difficulties and presents itself the task of creating a concealed siphon of the type described in the introduction, which in simple Way can be cleaned. In particular, it should also be possible to use the drain channel effortlessly and without having to remove the concealed siphon, for example, to insert a cleaning pen into it. Here strong deformations of the Cleaning pen can be avoided.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Tauch-Rohrteil des Tauchrohres integral mit dem Steig-Rohrteil nach der Art kommunizierender Gefäße unter Bildung eines Sifons ausgebildet ist.This object is achieved in that the dip tube part of the dip tube integral with the riser pipe part in the manner of communicating vessels to form a Sifons is trained.

Aus der DE-A - 31 09 384 ist ein Unterputzsifon bekannt, bei dem in einem in eine Wand eingemauerten Kasten ein Gehäuse lösbar eingesetzt ist, welches Gehäuse durch eine lotrechte Querwand geteilt ausgebildet ist, wobei sich in jedem der Teile einen Sifon bildende Tauchwände befinden. Hierbei ist der von der Eintrittsöffnung in das Gehäuse abwärts führende Kanal, der in einen einen Steig-Rohrteil bildenden aufwärts führenden Kanal mündet, mit dem vom Steig-Rohrteil wiederum abwärts führenden Kanal einstückig ausgebildet. From DE-A - 31 09 384 a concealed siphon is known, in which in a wall walled box a housing is detachably inserted, which housing by a vertical The transverse wall is divided, with a siphon forming in each of the parts Diving walls. Here is the downward from the inlet opening into the housing leading channel, which opens into an upwardly leading channel forming a riser pipe part, integrally formed with the channel leading downward again from the riser pipe part.

Eine einfache Zugänglichkeit zum Gehäuse des Unterputzsifons durch eine besonders leichte Anbringung und Entfernung des in das Gehäuse mündenden Ableitungsrohres bei absoluter Dichtheit zwischen dem Ableitungsrohr und dem Gehäuse ist gemäß einer bevorzugten Ausführungsform dann gegeben, wenn das Tauchrohr sowohl gegenüber dem Gehäuse an der Einlauföffnung als auch gegenüber dem Ableitungsrohr mittels einer einzigen Ringdichtung aus weichelastischem Material abgedichtet ist.Easy access to the housing of the concealed siphon thanks to a particularly easy one Attachment and removal of the discharge pipe opening into the housing at absolute Tightness between the discharge pipe and the housing is preferred Embodiment given when the immersion tube both against the housing on the Inlet opening and opposite to the discharge pipe by means of a single ring seal soft elastic material is sealed.

Hierbei weist zweckmäßig die Ringdichtung eine Stecköffnung für das Ableitungsrohr auf, wobei zum einfachen Ansetzen des Ablaufrohres vorzugsweise die Stecköffnung mit mindestens einer nach innen gerichteten und sich an das Ableitungsrohr außen anpressenden Ringflansch-Dichtlippe versehen ist.The ring seal expediently has a plug-in opening for the discharge pipe, the plug-in opening preferably being used for simple attachment of the drain pipe at least one facing inwards and pressing against the outside of the discharge pipe Ring flange sealing lip is provided.

Der Stützring bewirkt einen sicheren Sitz der Ringdichtung, auch wenn sie aus einem besonders weichen Material hergestellt ist.The ring seal advantageously has an outward opening and concentric with Center axis of the inlet opening circumferential groove into which a support ring from the outside can be used. The support ring ensures a secure fit of the ring seal, even if it is off is made of a particularly soft material.

Vorzugsweise weist der Stützring ein Winkelprofil auf, wobei der Stützring zweckmäßig einen konzentrisch zur Mittelachse der Einlauföffnung angeordneten Ringteil, der in die korrespondierend ausgebildete Ringnut der Ringdichtung einsetzbar ist, und weiters einen sich etwa rechtwinkelig hierzu und nach außen erstreckenden Ringflansch aufweist. Dies ergibt eine größere Steifheit des Stützringes, der dann besonders dünn und leicht anbringbar ausgebildet sein kann. Zudem gewährleistet das Winkelprofil des Stützringes dessen sicheren ordnungsgemäßen Sitz, der zudem leicht von außen optisch kontrollierbar ist.The support ring preferably has an angular profile, the support ring expediently one arranged concentrically to the central axis of the inlet opening, the ring part in the Correspondingly designed annular groove of the ring seal can be used, and furthermore one has approximately at right angles to this and outwardly extending ring flange. This gives one greater stiffness of the support ring, which is then made particularly thin and easy to attach can be. In addition, the angle profile of the support ring ensures its secure proper fit, which can also be easily checked from the outside.

Vorteilhaft ist der Ringflansch des Stützringes im eingebauten Zustand von einem Ringflansch der Ringdichtung von innen zumindest teilweise übergriffen, wodurch ein Einrasten des Stützringes in der Ringdichtung und damit dessen exakter Sitz auch bei Manipulationen am in die Ringdichtung eingesetzten Ableitungsrohr (z.B. bei dessen Einsetzen oder Entfernen) gewährleistet ist.The ring flange of the support ring in the installed state of an annular flange is advantageous the ring seal at least partially overlapped from the inside, causing the Support ring in the ring seal and thus its exact fit even when tampering with in the drain pipe inserted (e.g. when inserting or removing it) is guaranteed.
