Description

Die Erfindung betrifft einen Einbausifon für eine Abflußinstallation, insbesondere einen Waschmaschinen-Einbausifon, mit einem eine Geruchssperre aufweisenden Gehäuse, das eine Seitenwand mit einer Flüssigkeits-Eintrittsöffnung aufweist und in dessen Bodenbereich eine Flüssigkeits-Austrittsöffnung vorgesehen ist, wobei die Geruchssperre eine Scheidewand aufweist, die mit den Gehäusewänden einen von der Eintrittsöffnung zunächst abwärts bis zum Bodenbereich führenden Fallkanal, einen daran anschließenden sich aufwärts erstreckenden Steigkanal, einen an letzteren anschließenden und über die Eintrittsöffnung führenden Umlenkkanal und schließlich einen abwärts in die Austrittsöffnung mündenden und an den Umlenkkanal anschließenden Abströmkanal bildet.The invention relates to a built-in siphon for a drainage installation, in particular a washing machine built-in siphon, with a housing having an odor barrier, which has a side wall with a liquid inlet opening and in the bottom region of which a liquid outlet opening is provided, the odor block having a septum forms with the housing walls a drop channel leading from the inlet opening downwards to the floor area, an adjoining upwardly extending riser channel, a deflection channel adjoining the latter and leading via the inlet opening and finally an outflow channel opening downwards into the outlet opening and adjoining the deflection channel.

Ein Einbausifon dieser Art, der sich in der Praxis mit seiner flachen Bauart sehr bewährt hat, ist aus der AT-B - 343.555 bekannt. Dieser Sifon verhindert durch eine im Fallkanal eingesetzte Kugel, daß ein zuweilen auftretender Rückstau von Schmutzwasser aus anderen Haushaltsgeräten, wie z.B. Geschirrspülern od.dgl., oder aus dem Ablaufsystem selbst in das an den Sifon angeschlossene und gerade außer Betrieb befindliche Gerät eindringen kann.A built-in siphon of this type, which has proven itself in practice with its flat design, is known from AT-B - 343.555. This siphon prevents a backflow of dirty water from other household appliances, such as e.g. Dishwashers or the like, or can penetrate from the drain system itself into the device connected to the siphon and just out of operation.

Die besondere Art der Ausbildung der im Inneren des Gehäuses des Sifons vorgesehenen Kanäle ermöglicht neben einer besonders flachen - und daher mit Vorteil in eine Ausnehmung einer Wand unter Putz einsetzbaren - Bauart eine hohe Strömungsgeschwindigkeit der abzuleitenden Flüssigkeiten an den Stellen der Kanäle, an denen sich Schmutz ansammeln könnte, so daß solche Schmutzansammlungen im Gehäuse weitgehendst vermieden werden.The special type of design of the channels provided in the interior of the siphon enables, in addition to a particularly flat - and therefore advantageously used in a recess in a wall under plaster - design a high flow rate of the liquids to be drained at the locations of the channels where dirt could accumulate, so that such dirt accumulations in the housing are largely avoided.

Die Erfindung bezweckt eine Weiterentwicklung dieses Sifons dahingehend, daß eventuelle Schmutzansammlungen bzw. Verlegungen in einem an die Austrittsöffnung anschließenden Ablaufrohrsystem bzw. eine durch einen Rückstau bedingte Verlegung des Abströmkanals in einfacher Weise - ohne Ausbau des Sifons - beseitigt werden können. Insbesondere soll dies auch von ungelernten Personen durchführbar sein.The invention aims to further develop this siphon in such a way that possible dirt accumulations or relocations in a drain pipe system adjoining the outlet opening or a relocation of the outflow channel caused by a backflow can be removed in a simple manner - without removing the siphon. In particular, this should also be possible for unskilled people.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Gehäuse eine an sich bekannte, von außen verschließbare Öffnung aufweist, die in den Umlenkkanal und/oder den daran anschließenden Abströmkanal mündet und daß eine die Öffnung mit Abstand umgebende Abdeckhaube vorgesehen ist. Durch die spezielle Anordnung der Öffnung gelingt es, mit einem Reinigungsgerät, wie z.B. mit einer Reinigungsfeder, in einfacher Weise in den Abströmkanal zu gelangen und dort sowie im Ablaufkanal abgesetzten Schmutz zu entfernen.This object is achieved in that the housing has a known, closable opening from the outside, which opens into the deflection channel and / or the outflow channel adjoining it, and in that a covering hood surrounding the opening is provided. The special arrangement of the opening makes it easy to get into the outflow channel with a cleaning device, such as, for example, with a cleaning spring, and to remove dirt deposited there and in the outflow channel.

Die Abdeckhaube ermöglicht es, den Sifon in einfacher Weise in eine Wand einbauen zu können und hierbei die Zugänglichkeit zur Öffnung zu sichern.The cover hood enables the siphon to be easily installed in a wall and to ensure accessibility to the opening.

Aus der DE-C - 328 325 ist es bekannt, bei einem Geruchsverschluß für Wasserableitungsrohre am Übergang eines Kniestückes des Geruchsverschlusses zum Ableitungsrohr eine mit einer Reinigungsschraube verschließbare Öffnung vorzusehen.From DE-C - 328 325 it is known to provide an opening that can be closed with a cleaning screw in an odor trap for water drainage pipes at the transition from an elbow of the odor trap to the drainage pipe.

Ein Sifon für ein Abwasserbecken, wie ein Waschbecken oder eine Badewanne, mit einem abschraubbaren Deckel, ist aus der US-A - 788,454 bekannt. Hierbei bildet der abschraubbare Deckel einen Teil des Gehäuses, so daß das Innere des Gehäuses zugänglich ist. Der seitlich an das Gehäuse anschließende Ablaufkanal ist jedoch nur schwer zugänglich.A siphon for a wastewater basin, such as a wash basin or a bathtub, with a screw-on cover, is known from US-A-788,454. Here, the screw-off cover forms part of the housing so that the interior of the housing is accessible. However, the drain channel that connects to the side of the housing is difficult to access.

Ein keramischer WC-Wasserverschluß ist aus der GB-A - 9440 aus dem Jahr 1903 bekannt. Dieser Wasserverschluß weist an seiner oberen Umlenkung eine mit einem Schraubdeckel verschließbare Öffnung auf, wobei die Öffnung an einem Stutzen des Wasserverschlusses angeordnet ist.A ceramic toilet water seal is known from GB-A-9440 from 1903. At its upper deflection, this water seal has an opening which can be closed with a screw cap, the opening being arranged on a connecting piece of the water seal.

Eine besonders einfache Reinigungsmöglichkeit wird erfindungsgemäß dadurch sichergestellt, daß die Öffnung zumindest teilweise in einen absteigenden Ast des Umlenkkanals, der an den Abströmkanal anschließt, mündet, wobei zweckmäßig die Öffnung von einem an das Gehäuse anschließenden, an sich bekannten Rohrstutzen gebildet ist.A particularly simple cleaning option is ensured according to the invention in that the opening opens at least partially into a descending branch of the deflection channel which adjoins the outflow channel, the opening advantageously being formed by a pipe socket which is known and adjoins the housing.

Eine besonders platzsparende Anordnung der Öffnung - insbesondere für einen Einbausifon läßt sich vorteilhaft dadurch erzielen, daß an die Eintrittsöffnung ein etwa horizontaler, vom Gehäuse nach außen abstehender Eintrittsstutzen anschließt und daß der Rohrstutzen sich teilweise am Gehäuse und teilweise am Eintrittsstutzen abstützend angeordnet ist.A particularly space-saving arrangement of the opening - in particular for a built-in siphon, can advantageously be achieved by connecting the inlet opening with an approximately horizontal inlet connection protruding from the housing and by partially supporting the pipe connection on the housing and partly on the inlet connection.

Vorteilhaft ist der Rohrstutzen mit einer auf den Rohrstutzen aufschraubbaren, mit einer Dichtung versehenen Verschlußkappe verschließbar.The pipe socket can advantageously be closed with a sealing cap which can be screwed onto the pipe socket and is provided with a seal.

Vorteilhaft ist die Abdeckhaube mittels einer Schnappverbindung an am Gehäuse angeordneten und von diesem auskragenden Halteteilen angesetzt.The cover is advantageously attached by means of a snap connection to holding parts arranged on the housing and projecting therefrom.

Eine einfache Ausbildung der Abdeckhaube ist dadurch gekennzeichnet, daß die Abdeckhaube nach vorne, d.h. zur Seitenwand des Gehäuses, an der die Eintrittsöffnung bzw. an der der an die Eintrittsöffnung ansetzende Eintrittsstutzen angeordnet sind, offen ist.A simple design of the cover is characterized in that the cover is open to the front, ie to the side wall of the housing on which the inlet opening or on which the inlet connection piece adjoining the inlet opening is arranged.

Um ein Verlegen der verschließbaren Öffnung mit Baustoffen, wie Mörtel, und eine Beschädigung des Sifons bei und nach seinem Einbau in die Wand, z.B. bei einem nachfolgenden Verputzen oder Verfliesen der Wand, mit Sicherheit zu vermeiden, ist vorteilhaft eine die Abdeckhaube und zumindest den Teil des Gehäuses, der die Eintrittsöffnung bzw. den an die Eintrittsöffnung anschließenden Eintrittsstutzen trägt, bedeckende Schutzhaube vorgesehen, wobei zweckmäßig die Schutzhaube einen freien Rand aufweist, mit dem sie über die Abdeckhaube und zumindest teilweise über das Gehäuse schiebbar ist.In order to reliably avoid laying the closable opening with building materials, such as mortar, and damage to the siphon during and after its installation in the wall, for example in the event of subsequent plastering or tiling of the wall, it is advantageous to cover the cover and at least the part of the housing that the Inlet opening or the inlet connection adjoining the inlet opening, covering protective hood is provided, the protective hood expediently having a free edge with which it can be pushed over the covering hood and at least partially over the housing.

Zur Anpassung der Schutzhaube an die Einbautiefe des Sifons sind vorteilhaft Seitenwände der Schutzhaube mit mehreren zueinander und zur Frontwand der Schutzhaube parallelen Rillen versehen.To adapt the protective hood to the installation depth of the siphon, side walls of the protective hood are advantageously provided with a plurality of grooves parallel to one another and to the front wall of the protective hood.

Zur Erleichterung der Anpassung der Schutzhaube sind vorteilhaft die Rillen durch schlitzartige, die Seitenwände durchsetzende Ausnehmungen unterbrochen, wodurch in einfacher Weise ein Schneidwerkzeug angesetzt werden kann.To facilitate the adaptation of the protective hood, the grooves are advantageously interrupted by slot-like recesses penetrating the side walls, as a result of which a cutting tool can be attached in a simple manner.

Um trotz einer möglichst flachen Ausführung des Sifons und trotz einer geringen Einbautiefe eine gute Zugänglichkeit zur Öffnung und zum Verschluß der Öffnung zu erreichen, ist die die Eintrittsöffnung aufweisende vordere Seitenwand des Gehäuses ausgehend vom Bodenbereich des Gehäuses nach hinten zur Rückwand des Gehäuses unter Verengung des Querschnitts des Gehäuses geneigt angeordnet.In order to achieve good accessibility to the opening and the closure of the opening despite the flat design of the siphon and despite the shallow installation depth, the front side wall of the housing, which has the inlet opening, is to the rear from the bottom area of the housing to the rear wall of the housing, narrowing the cross section of the housing arranged inclined.

Die Erfindung ist nachfolgend anhand der Zeichnung an einem Ausführungsbeispiel näher erläutert, wobei Fig. 1 einen Vertikalschnitt durch einen in eine Wand eingebauten Sifon, Fig. 2 eine Darstellung eines gemäß der Linie II-II der Fig. 1 geführten Schnittes und Fig. 3 einen gemäß der Linie III-III der Fig. 2 geführten Schnitt zeigen.The invention is explained in more detail below with reference to the drawing using an exemplary embodiment, wherein FIG. 1 shows a vertical section through a siphon built into a wall, FIG. 2 shows a section made according to line II-II of FIG. 1 and FIG. 3 shows a section show section taken along the line III-III of Fig. 2.

Die in der Zeichnung dargestellte Ausführungsform betrifft einen Waschmaschinen-Einbausifon. Der Sifon weist ein aus Kunststoff gefertigtes Gehäuse 1 auf, in dessen Innerem eine Geruchssperre angeordnet ist. Das Abwasser der Waschmaschine tritt durch eine Eintrittsöffnung 2 in das Gehäuse 1 ein, die an der vorderen Seitenwand 3 des Gehäuses 1 vorgesehen ist. Im Bodenbereich 4 des Gehäuses 1 ist eine Austrittsöffnung 5 für das Abwasser vorgesehen. Sowohl an die Eintrittsöffnung 2 als auch an die Austrittsöffnung 5 schließen Stutzen 6, 7 an, die vorteilhaft mit dem Gehäuse 1 einteilig hergestellt sind. Der Eintrittsstutzen 6 ist mit einem Außengewinde 8 versehen, an dem der Abwasserschlauch der Waschmaschine aufschraubbar ist.The embodiment shown in the drawing relates to a washing machine built-in siphon. The siphon has a housing 1 made of plastic, in the interior of which an odor barrier is arranged. The waste water from the washing machine enters the housing 1 through an inlet opening 2, which is provided on the front side wall 3 of the housing 1. An outlet opening 5 for the waste water is provided in the bottom region 4 of the housing 1. Both the inlet opening 2 and the outlet opening 5 are joined by connecting pieces 6, 7, which are advantageously produced in one piece with the housing 1. The inlet connector 6 is provided with an external thread 8 on which the sewage hose of the washing machine can be screwed on.

Das Gehäuse 1 weist horizontal geschnitten in etwa einen rechteckigen, flachen Querschnitt auf, wie insbesondere aus Fig. 3 ersichtlich ist, wodurch sich eine nur geringe Einbautiefe 9 ergibt.The housing 1 has a horizontally cut, approximately rectangular, flat cross-section, as can be seen in particular in FIG. 3, which results in only a small installation depth 9.

Die Geruchssperre wird von einer im Inneren des Gehäuses vorgesehenen Scheidewand 10 und den Gehäusewänden 11, 12, 13 gebildet, wobei die Scheidewand 10, wie inbesondere aus Fig. 2 erkennbar ist, von der Austrittsöffnung 5 ausgeht, die Eintrittsöffnung 2 umschließt und sich mit einem freien Ende 14 bis in die Nähe des Bodens 4 des Gehäuses 1 erstreckt. Die Scheidewand 10 bildet somit mit den Gehäusewänden 3, 11, 12 und 13 einen von der Eintrittsöffnung zunächst abwärts bis zum Boden 4 des Gehäuses 1 führenden Fallkanal 15, einen daran anschließenden sich aufwärts erstreckenden Steigkanal 16, einen an letzteren anschließenden und über die Eintrittsöffnung 2, d.h. den die Eintrittsöffnung umfassenden Teil 17 der Scheidewand 10 führenden Umlenkkanal 18 und letztendlich einen abwärts in die Austrittsöffnung 5 mündenden und an den Umlenkkanal 18 anschließenden Abströmkanal 19. Die Strömungsrichtung des abzuleitenden Abwassers ist durch die eingezeichneten Pfeile P1 bis P4 veranschaulicht.The odor barrier is formed by a partition 10 provided in the interior of the housing and the housing walls 11, 12, 13, the partition 10, as can be seen in particular in FIG. 2, originating from the outlet opening 5, enclosing the inlet opening 2 and with one free end 14 extends into the vicinity of the bottom 4 of the housing 1. The partition 10 thus forms with the housing walls 3, 11, 12 and 13 a drop channel 15 leading from the inlet opening down to the bottom 4 of the housing 1, an adjoining upwardly extending riser channel 16, an adjoining the latter and via the inlet opening 2 , ie the part 17 of the dividing wall 10 which surrounds the inlet opening and ultimately a discharge channel 19 which opens downwards into the outlet opening 5 and adjoins the deflection channel 18. The direction of flow of the waste water to be discharged is illustrated by the arrows P 1 to P 4 .

In den von der Eintrittsöffnung 2 abwärts führenden Fallkanal 15 ist eine Kugel 20 eingesetzt, die im Falle eines Rückstaus die Eintrittsöffnung 2 verschließt. Die Schließlage der Kugel 20 ist in Fig. 1 strichliert angedeutet. Die Kugel 20 besteht aus einem Werkstoff, der ein spezifisches Gewicht geringfügig geringer als das des Abwassers aufweist.In the drop channel 15 leading down from the inlet opening 2, a ball 20 is inserted, which closes the inlet opening 2 in the event of a backflow. The closed position of the ball 20 is indicated by dashed lines in FIG. 1. The ball 20 is made of a material that has a specific weight slightly less than that of the waste water.

Unterhalb der Eintrittsöffnung 2 befindet sich eine mit einer Verschlußkappe 21 und einer Dichtung 22 verschließbare Öffnung 23, die zum Einsetzen der Kugel 20 dient und die weiters ein Putzen des Fallkanals 15 bzw. ein Entfernen von den Fallkanal 15 verlegenden Fremdkörpern ermöglicht.Below the inlet opening 2 there is an opening 23 which can be closed with a closure cap 21 and a seal 22 and which is used for inserting the ball 20 and which further enables cleaning of the drop channel 15 or removal of foreign bodies which move the drop channel 15.

Das Gehäuse 1 weist an seinem Oberteil eine von außen verschließbare Öffnung 24 auf, die gemäß dem dargestellten Ausführungsbeispiel in den Umlenkkanal 18 mündet, u.zw. zumindest teilweise in den absteigenden Ast 18' des Umlenkkanals 18, in dem das abzuleitende Abwasser wiederum abwärts strömt. Durch diese mit einer Verschlußkappe 25 mit Dichtung 26 verschließbare Öffnung 24 läßt sich in besonders einfacher Weise eine Putzfeder, wie durch die strichlierte Linie F veranschaulicht, direkt in den Abflußkanal einführen, ohne daß ein Ausbau des Sifons erforderlich ist. Die Öffnung 24 ist von einem am Gehäuse 1 im Abstand dessen Rückwand 13 angeordneten Rohrstutzen 27 gebildet, der über Stützwände 28 am Eintrittsstutzen 6 und am Gehäuseoberteil abgestützt ist.On its upper part, the housing 1 has an opening 24 which can be closed from the outside and which, according to the exemplary embodiment shown, opens into the deflection channel 18, etc. at least partially in the descending branch 18 'of the deflection channel 18, in which the wastewater to be discharged in turn flows downwards. Through this opening 24, which can be closed with a closure cap 25 with a seal 26, a cleaning spring, as illustrated by the dashed line F, can be inserted directly into the drainage channel in a particularly simple manner, without the siphon having to be removed. The opening 24 is formed by a pipe socket 27 arranged on the housing 1 at a distance from the rear wall 13 thereof, which is supported by support walls 28 on the inlet socket 6 and on the upper housing part.

Damit trotz Anordnung der Öffnung 24 der Sifon möglichst flach ausgebildet sein kann und nur eine sehr geringe Einbautiefe benötigt, ist die die Eintrittsöffnung 2 aufweisende vordere Seitenwand 3 des Gehäuses 1 geneigt ausgebildet, u.zw. ausgehend vom Boden 4 unter Querschnittsverengung des Gehäuses 1 nach hinten zur Rückwand 13 des Gehäuses 1. Hierdurch gelingt es, an der vorderen Seitenwand im oberen Bereich des Gehäuses genügend Freiraum zur Anordnung der Öffnung 24 mit Verschlußkappe 25 zu schaffen, so daß Manipulationen an der Verschlußkappe auf kleinstem Raum ohne Schwierigkeiten durchführbar sind. Die sich hierdurch ergebenden Querschnittsverengungen im Inneren des Gehäuses 1 bewirken eine Erhöhung der Strömungsgeschwindigkeit des Abwassers und dadurch eine gute Selbstreinigung des Sifons.So that, despite the arrangement of the opening 24, the siphon can be made as flat as possible and requires only a very small installation depth, the front side wall 3 of the housing 1 which has the inlet opening 2 is inclined, etc. starting from the bottom 4 below Cross-sectional constriction of the housing 1 to the rear to the rear wall 13 of the housing 1. In this way, it is possible to create sufficient space on the front side wall in the upper region of the housing for arranging the opening 24 with the closure cap 25, so that manipulations on the closure cap in the smallest space without difficulty are feasible. The resulting cross-sectional constrictions in the interior of the housing 1 cause an increase in the flow rate of the waste water and thereby a good self-cleaning of the siphon.

Um einen einfachen Einbau des Sifons in eine Wand unter Freihaltung der verschließbaren Öffnung 24 samt Verschlußkappe 25 zu ermöglichen, ist dieser mit einer Abdeckhaube 29 versehen, die zur Vorderseite des Sifons hin offen ausgebildet ist und die Rückwand 13 sowie die Seitenwände 11 und 12 verlängert. Diese Abdeckhaube 29 umgibt die Öffnung 24 bzw. die an den Rohrstutzen 27 aufschraubbare Verschlußkappe 25 mit Abstand 30, so daß die Verschlußkappe 25 leicht manipulierbar ist und zudem genügend Platz zum Einführen einer Putzfeder vorhanden ist. Die Abdeckhaube 29 ist vorteilhaft mit dem Gehäuse 1 nicht einstückig ausgebildet, sondern mit diesem über eine Schnappverbindung 31 verbunden, wobei am oberen Teil des Gehäuses seitlich auskragende Halteteile 32 angeordnet sind. die an ihrem Ende mit Schnappnasen 33 ausgestattet sind, an denen Gegenschnappnasen 34 der Abdeckung ansetzbar sind.In order to allow a simple installation of the siphon in a wall while keeping the closable opening 24 together with the closure cap 25, this is provided with a cover 29 which is open towards the front of the siphon and extends the rear wall 13 and the side walls 11 and 12. This cover 29 surrounds the opening 24 or the screw cap 25 which can be screwed onto the pipe socket 27 at a distance 30, so that the screw cap 25 is easy to manipulate and there is also sufficient space for inserting a cleaning spring. The cover 29 is advantageously not formed in one piece with the housing 1, but is connected to the latter via a snap connection 31, with laterally projecting holding parts 32 being arranged on the upper part of the housing. which are equipped at their end with snap lugs 33, on which counter-snap lugs 34 of the cover can be attached.

Um eine Beschädigung des Sifons beim Einbau auszuschließen bzw. um ein Eindringen von Putzmaterial oder Verunreinigungen in die Abdeckhaube 29 bzw. in den Eintrittsstutzen 6 zu vermeiden, ist eine vorzugsweise aus Polypropylen oder einem Recycling-Kunststoff gefertigte Schutzhaube 35 vorgesehen, die mit ihrem freien Rand 36 über die Abdeckhaube 29 und das Gehäuse 1 schiebbar ist, gegebenenfalls unter Einrastung. Die Frontwand 37 der Schutzhaube 35 ist mit einer Vertiefung 38 ausgestattet, in die der Eintrittsstutzen 6 einsetzbar ist, wodurch ein guter Halt der Schutzhaube 35 am Sifon sichergestellt ist.In order to prevent damage to the siphon during installation or to prevent the penetration of cleaning material or contaminants into the cover hood 29 or into the inlet connector 6, a protective hood 35, preferably made of polypropylene or a recycled plastic, is provided, with its free edge 36 can be pushed over the cover 29 and the housing 1, if necessary with latching. The front wall 37 of the protective hood 35 is equipped with a recess 38 into which the inlet connector 6 can be inserted, thereby ensuring that the protective hood 35 is held securely on the siphon.

An der Außenseite der Schutzhaube 35 sind an den die Frontwand 37 umgebenden Seitenwänden in einem gewissen Bereich zueinander parallele Rillen 39 vorgesehen, so daß ein Abschneiden und Entfernen des nicht benötigten Teiles der Schutzhaube 35, d.h. des Teiles, der über die fertig verflieste bzw. verputzte Wand 40 vorsteht, in einfacher Weise möglich ist. Der übrige Teil der Abdeckhaube verbleibt eingemauert. Das Abschneiden kann durch die Rillen 39 unterbrechende schlitzförmige Ausnehmungen 39', die die Seitenwände durchbrechen und das gefahrlose Einsetzen eines Schneidwerkzeuges ermöglichen, erleichtert werden.On the outside of the protective hood 35 parallel grooves 39 are provided in a certain area on the side walls surrounding the front wall 37, so that a cutting and removal of the unnecessary part of the protective hood 35, ie the part that tiled or plastered over the finished Wall 40 protrudes, is possible in a simple manner. The rest of the cover remains bricked up. The cutting can be facilitated by the slot 39 interrupting slot-shaped recesses 39 'which break through the side walls and allow the safe insertion of a cutting tool.

Mit einer Frontabdeckplatte 41, die eine Durchtrittsöffnung für den Eintrittsstutzen 6 aufweist, läßt sich der Sifon verkleiden.The siphon can be covered with a front cover plate 41, which has a passage opening for the inlet connection 6.

Die Erfindung beschränkt sich nicht auf das in der Zeichnung dargestellte Ausführungsbeispiel, sondern sie kann in verschiedener Hinsicht modifiziert werden. Beispielsweise ist es möglich, den Sifon in ähnlicher Bauweise für andere Geräte zu verwenden, beispielsweise für Geschirrspülmaschinen, Absaugpumpen etc. Die verschließbare Öffnung 24 muß nicht unbedingt in den Umlenkkanal 18 münden, sondern sie kann auch in den an den Umlenkkanal 18 anschließenden Abströmkanal 19 münden.The invention is not limited to the embodiment shown in the drawing, but can be modified in various ways. For example, it is possible to use the siphon in a similar design for other devices, for example for dishwashers, suction pumps, etc. The closable opening 24 does not necessarily have to open into the deflection channel 18, but it can also open into the outflow channel 19 adjoining the deflection channel 18 .
