Description

Die Erfindung bezieht sich auf einen Geruchsverschluss, der vorzugsweise für den Dach-, Terrassen- oder Balkonwasserablauf zu verwenden ist. Dazu wird der Geruchsverschluss zwischen dem unteren Ende eines Ablaufrohrs einer Dachrinne,Terrasse oder eines Balkons und dem oberen Ende einer Anschlussleitung einer Kanalisation eingefügt. Dabei hindert der Geruchsverschluss die Kanalgase daran, in das Ablaufrohr', in dem diese aggressiven Gase zu Korrosionsschäden führen, und durch das Ablaufrohr zur Dachrinne und zum Dach bzw. zum Balkon oder zur Terrasase und durch offene Fenster oder Türen ins Gebäude zu gelangen.The invention relates to an odor trap, which is preferably to be used for the roof, terrace or balcony water drain. For this purpose, the odor trap is inserted between the lower end of a drain pipe of a gutter, terrace or balcony and the upper end of a sewer connection line. The odor trap prevents the sewer gases from entering the drain pipe ', in which these aggressive gases lead to corrosion damage, and through the drain pipe to the gutter and roof, or to the balcony or terrace, and through open windows or doors into the building.

Die üblichen Geruchsverschlüsse für diesen Zweck beruhen auf dem Prinzip des Wasserverschlusses (Siphon), sie haben ein U-förmiges Rohrstück mit Ueberlauf oder einen Behälter, in den das Ablaufrohr eintaucht. Das im U-Rohr oder Behälter stehende Wasser verhindert ein Hindurchströmen von Gasen, während Wasser bis auf die jeweils im U-Rohr oder Behälter stehenbleibende Wassermenge ungehindert hindurchfliessen kann. Infolge der grundsätzlich erforderlichen, zweimaligen Umlenkung der Wasserströmung (bei einem verbreiteten Regenrohrsiphon um zwei mal 180°), neigen solche Geruchsverschlüsse dazu, zu verstopfen, und sie sind dann umständlich zu reinigen. Das stehende Wasser führt zwar zu einem dichten Verschluss, doch verdampft das Wasser bei heissem, trockenen Klima, wenn es längere Zeit nicht regnet. Dann können solche Geruchsverschlüsse infolge eines nicht ausreichenden Wasserstandes das Hindurchströmen der Gase nicht mehr verhindern. Und wenn das stehende Wasser bei tieferen Temperaturen gefriert, kann dies zu Rissen im Gehäuse des Geruchsverschlusses führen.The usual odor traps for this purpose are based on the principle of water trap (siphon), they have a U-shaped pipe section with an overflow or a container into which the drain pipe is immersed. The water in the U-tube or container prevents gases from flowing through, while water except for each in The U-pipe or container can allow the remaining amount of water to flow through unhindered. As a result of the two-fold redirection of the water flow (in the case of a common rain pipe siphon by twice 180 °), such odor traps tend to become blocked and are then difficult to clean. The standing water leads to a tight seal, but the water evaporates in a hot, dry climate if it does not rain for a long time. Then such odor traps can no longer prevent the gases from flowing due to an insufficient water level. And if the standing water freezes at lower temperatures, this can lead to cracks in the odor trap housing.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, einen Geruchsverschluss zu schaffen, der nicht zu Verstopfungen neigt und, falls trotzdem erforderlich, leicht (einschliesslich der Anschlussleitung der Kanalisation) zu reinigen ist und unabhängig von den klimatischen Einflüssen wirksam bleibt.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of creating an odor trap which is not prone to blockages and, if necessary, is easy to clean (including the connection line to the sewage system) and remains effective regardless of the climatic influences .

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass der erfindungsgemässe Geruchsverschluss infolge des gerade abwärts verlaufenden Strömungsweges nicht zu Verstopfungen neigt und, soweit überhaupt noch erforderlich, einfach, schnell und gründlich bis weit in das anschliessende Kanalanschlussrohr hinein gereinigt werden kann. Der Vermeidung von Verstopfungen dienen auch die Anordnung der Klappenschwenkachse ausserhalb des Strömungsweges und die, bezogen auf die Klappenschwenkachse, schräg abwärts verlaufende Lage des Sitzes, wegen der sich Verunreinigungen in Ruhelage (Schliesslage) der Klappe an deren tiefsten Stelle ansammeln, wo sie besonders wirksam weggespült werden, sobald Wasser auf die Klappe trifft. Dabei wirkt das Wasser zuerst an dieser Stelle, an der es wegen des grössten Abstandes von der Klappenschwenkachse das grösste Drehmoment auf die Klappe ausübt. Indem die Klappe in ihrer Schliesslage durch ein Gegengewicht gehalten ist, das sich in dieser Klappenlage annähernd auf der Höhe der Klappenschwenkachse befindet, wird erreicht, dass das in Schliessrichtung wirkende Drehmoment bei geschlossener Klappe am grössten ist und beim Oeffnen derselben abnimmt. Dadurch dichtet die Klappe in Ruhelage zuverlässig, stellt aber für die Wasserströmungen einen mit zunehmender Strömung abnehmenden Widerstand dar.The advantages achieved by the invention are essentially to be seen in the fact that the odor trap according to the invention does not tend to become blocked due to the straight downward flow path and, if necessary at all, can be cleaned simply, quickly and thoroughly as far as into the adjoining sewer connection pipe. The arrangement of the valve pivot axis outside of the flow path and the position of the seat, which runs obliquely downwards in relation to the valve pivot axis, also serve to avoid blockages, because of the contamination in the rest position (closed position) of the valve accumulating at its lowest point, where it is particularly effectively washed away be like that soon water hits the flap. The water acts first at this point, where it exerts the greatest torque on the valve due to the greatest distance from the valve pivot axis. By holding the flap in its closed position by a counterweight, which in this flap position is approximately at the height of the flap pivot axis, the result is that the torque acting in the closing direction is greatest when the flap is closed and decreases when the flap is opened. As a result, the flap seals reliably in the rest position, but represents a resistance to the water flow that decreases with increasing flow.

Im folgenden wird die Erfindung im Zusammenhang mit ihrer vorzugsweisen Verwendung anhand von lediglich ein Ausführungsbeispiel darstellenden, teilweise nur schematischen Zeichzurgen näher erläutert.The invention is explained in more detail below in connection with its preferred use on the basis of drawings, which in some cases are only schematic, representing only one exemplary embodiment.

Im gerade abwärts verlaufenden Strömungsweg A-B des dargestellten Geruchsverschlusses sind eine Klappe 1 und der dazu gehörende Sitz 2 angeordnet. Die Schwenkachse 4 der Klappe 1 (vergl. deren Zapfen 3 in Fig. 2) verläuft neben dem Sitz 2 ausserhalb des Strömungsweges A-B. Der Sitz 2 ist in Bezug auf die Klappenschwenkachse 4 schräg abwärts geneigt, d.h. in einer von der Schwenkachse 4 schräg abwärts verlaufenden Ebene angeordnet oder parallel zu einer solchen Ebene, je nach der Lage, welche die Schwenkachse 4 in Bezug auf die Klappenebene hat. Gegen die Schwerkraft der Klappe 1 wirkt ein Gegengewicht 6, dessen Massenmittelpunkt in Ruhelage der Klappe 1 annähernd auf derselben Höhe wie deren Schwenkachse 4 liegt. Die Klappe 1 kann zusammen mit ihren Zapfen 3 und ihrem Gegengewicht 5 einstückig aus Metall bestehen.A flap 1 and the associated seat 2 are arranged in the straight downward flow path AB of the odor trap shown. The pivot axis 4 of the flap 1 (see. The pin 3 in Fig. 2) runs next to the seat 2 outside the flow path AB. The Seat 2 is inclined downwards with respect to the flap pivot axis 4, that is to say arranged in a plane running downwards from the pivot axis 4 or parallel to such a plane, depending on the position of the pivot axis 4 in relation to the flap plane. A counterweight 6 acts against the gravity of the flap 1, the center of mass of which, when the flap 1 is at rest, is approximately at the same height as its pivot axis 4. The flap 1, together with its pin 3 and its counterweight 5, can be made in one piece from metal.

Das Gehäuse des Geruchsverschlusses, das aus Kunststoff oder Metall (Blech oder Guss) bestehen kann, hat einen rohrförmigen Gehäusehauptteil 6, in dem der geradlinige Strömungsweg A-B verläuft, und einen kastenförmigen Gehäuseansatz 7. Das obere Ende 8 des rohrförmigen Teils 6 ist an das (nicht dargestellte) untere Ende eines Wasserablaufrohres anzuschliessen. Das untere Ende 9 des rohrförmigen Teiles 6 ist dicht mit einer (nicht dargestellten) Anschlussleitung einer Kanalisation zu verbinden, so wie bei bekannten Geruchsverschlüssen üblich. Die Klappe 1 und der Sitz 2 sind im rohrförmigen Teil 6, das Gegengewicht 5, die Zapfen 3 und dazugehörige Zapfenlager 10 sind im Gehäuseansatz 7 angeordnet. Eine Querschnittshälfte des rohrförmigen Teils 6 greift zwischen die in Fig. 1 vordere und hintere Wand 11 und 12 des Gehäuseansatzes 7 hinein. Dabei hat die im Ansatz 7 verlaufende Mantelhälfte 13 des rohrförmigen Teils 6 eine Aussparung, die sich vom Sitz 2 bis zum Boden 14 des Ansatzes 7 über den halben Rohrumfang erstreckte so dass die Mantelhälfte 13 unterhalb des Sitzes 2 bis an den Boden 14 herausgeschnitten ist. Der obere Rand der Aussparung ist mit 15, der untere ist mit 16 bezeichnet.The housing of the odor trap, which can be made of plastic or metal (sheet metal or cast iron), has a tubular housing main part 6, in which the rectilinear flow path AB runs, and a box-shaped housing attachment 7. The upper end 8 of the tubular part 6 is connected to the ( not shown) to connect the lower end of a water drain pipe. The lower end 9 of the tubular part 6 is to be tightly connected to a sewer connection line (not shown), as is customary in the case of known odor traps. The flap 1 and the seat 2 are in the tubular part 6, the counterweight 5, the pin 3 and associated pin bearing 10 are arranged in the housing shoulder 7. A cross-sectional half of the tubular part 6 engages between the front and rear walls 11 and 12 of the housing extension 7 in FIG. 1. The jacket half 13 of the tubular part 6 running in the neck 7 has a recess which extends from the seat 2 to the bottom 14 of the neck 7 over half the tube circumference, so that the jacket half 13 is cut out below the seat 2 to the bottom 14. The upper edge of the recess is 15, the lower is 16.

Die obere Wand 17 des Ansatzes 7 ist mit einer Oeffnung 18 versehen, deren lichte Weite nicht wesentlich kleiner als die des rohrförmigen Teiles 6 ist. Die Oeffnung ist durch einen mittels Schrauben 19 lösbar befestigten Dekkel 20 verschlossen, wobei eine Dichtung 21 einen luftdichten Verschluss bewirkt. Die Lager 10 für die Zapfen 3 der Klappe 1 sind an der vorderen bzw. hinteren Ansatzwand 11 bzw. 12 angeordnete U-förmige Lagerschalen, aus denen die Zapfen 3 nach oben herausgehoben werden können. Dies ermöglicht es, die Klappe 1 mit ihrem Gegengewicht 5 aus dem Gehäuse 6/7 bei abgenommenem Deckel 20 herauszunehmen, nachdem sie in die strichpunktiert dargestellte Lage geschwenkt wurde. Dazu ist der Abstand des Gegengewichts 5 von der Wand 22 des Gehäuseansatzes 7 so bemessen, dass man das Gegengewicht 5 in Schliesslage der Klappe 1 erfassen kann, um die Klappe 1 mit dem Gegengewicht 5 in die Offenstellung zu schwenken und herauszunehmen. Zu diesem Zwecke könnte das Gegengewicht 5 auch mit einer geeigneten (nicht dargestellten) Handhabe versehen sein.The upper wall 17 of the extension 7 is provided with an opening 18, the clear width of which is not significantly smaller than that of the tubular part 6. The opening is closed by a cover 20 which is detachably fastened by means of screws 19, a seal 21 effecting an airtight closure. The bearings 10 for the pins 3 of the flap 1 are U-shaped bearing shells arranged on the front and rear extension walls 11 and 12, from which the pins 3 can be lifted upwards. This makes it possible to remove the flap 1 with its counterweight 5 from the housing 6/7 with the cover 20 removed after it has been pivoted into the position shown in broken lines. For this purpose, the distance between the counterweight 5 and the wall 22 of the housing extension 7 is dimensioned such that the counterweight 5 can be grasped in the closed position of the flap 1 in order to pivot the flap 1 with the counterweight 5 into the open position and to remove it. For this purpose, the counterweight 5 could also be provided with a suitable handle (not shown).

Ein Anschlag 23 begrenzt die Oeffnungsbewegung der Klappe 1. Die Schenkel der U-förmigen Lagerschalen 10 können federnd sein und oben einen Abstand haben, der kleiner als der Durchmesser der Zapfen 3 ist, so dass diese nur unter Ueberwindung der Federkraft herausgehoben werden, sich aber nicht unerwünscht aus den Lagerschalen 10 lösen können, beispielsweise wenn eine grössere Wasserströmung unsymmetrisch auf die Klappe 1 trifft. Die Seitenwand des Gehäuseansatzes 7 verläuft anschliessend an den Wandteil 22 schräg abwärts (Wandteil 24) zum Boden 14 des Gehäuseansatzes 7 am unteren Rand 16 der Aussparung. Dabei hat der schräge Wandteil 24 von der Schwenkachse 4 der Klappe 1 einen Abstand, der nicht wesentlich kleiner als die lichte Weite des rohrförmigen Teils 6 ist. Der Wandteil 24 dient als Führung für eine Putzrute, die erforderlichenfalls zur Reinigung des unteren Teiles des Geruchsverschlusses und der mit dessen unterem Ende 9 verbundenen (nicht dargestellten) Anschlussleitung der Kanalisation eingeführt werden kann, nachdem der Deckel 20 abgenommen und die Klappe 1 mit ihrem Gegengewicht 5 herausgenommen wurde.A stop 23 limits the opening movement of the flap 1. The legs of the U-shaped bearing shells 10 can be resilient and have a distance at the top that is smaller than the diameter of the pins 3, so that they are only lifted out while overcoming the spring force, but are lifted out cannot undesirably detach from the bearing shells 10, for example if a larger water flow hits the flap 1 asymmetrically. The side wall of the housing extension 7 then runs obliquely downwards on the wall part 22 (wall part 24) to the bottom 14 of the housing extension 7 at the lower edge 16 of the recess. In this case, the inclined wall part 24 is at a distance from the pivot axis 4 of the flap 1 that is not significantly smaller than the inside width of the tubular part 6. The wall part 24 serves as a guide for a cleaning rod, which, if necessary, can be introduced for cleaning the lower part of the odor trap and the sewer connection line (not shown) connected to its lower end 9 after the cover 20 has been removed and the flap 1 with its counterweight 5 has been removed has been.

Abweichend vom gezeichneten Ausführungsbeispiel können die Zapfen 3 am Gehäuseansatz 7 und die Lagerschalen 10 an der Klappe 1 angeordnet sein, wobei die letzteren in Klappenruhelage mit der offenen U-Seite nach unten oder schräg nach unten zu richten sind, und der Abstand der Zapfen 3 von der Mantelhälfte 13 des rohrförmigen Gehäuseteils 6 so gross bemessen sein muss, dass die Lagerschalen 10 in der in Fig. 1 strichpunktiert gezeichneten Stellung der Klappe 1 von den Zapfen 3 abgezogen werden können.In a departure from the exemplary embodiment shown, the pins 3 can be arranged on the housing shoulder 7 and the bearing shells 10 on the flap 1, the latter being in the flap rest position with the open U-side pointing downwards or obliquely downwards, and the distance of the pins 3 from the jacket half 13 of the tubular housing part 6 must be dimensioned so large that the bearing shells 10 can be pulled off the pin 3 in the position of the flap 1 shown in broken lines in FIG. 1.

Bei der gezeichneten Ausführungsform verläuft der Sitz 2 an der Innenseite des rohrförmigen Gehäusehauptteils 6. Dadurch ist der lichte Querschnitt des Strömungsweges A-B im Bereich des Sitzes 2, in Strömungsrichtung gesehen, etwas kleiner als ober- und unterhalb des Sitzes 2. Um dies zu vermeiden, ist bei einer nicht gezeichneten Ausführungsform des Geruchsverschlusses die dem Gehäuseansatz 7 gegenüberliegende Umfangshälfte des rohrförmigen Hauptteils 6 mit einer Ausbuchtung versehen, und der Gehäuseansatz 7 ist der Ausbuchtung angepasst breiter ausgeführt, wobei eine Umfangshälfte des Sitzes in der Ausbuchtung und die andere Umfangshälfte unter dem unteren Rand der in Fig. 1 und 3 mit 13 bezeichneten Mantelhälfte des rohrförmigen Gehäusehauptteils angeordnet ist. Die Ausbuchtung ist unterhalb des Sitzes so zu bemessen, dass die Schwenkbarkeit der Klappe 1 gewährleistet ist. Dies ermöglicht es, einen Sitz zu verwenden, dessen lichte Oeffnung, in Strömungsrichtung A-B gesehen, mit dem lichten Querschnitt des rohrförmigen Gehäusehauptteils 6 übereinstimmt oder sogar grösser ist.In the embodiment shown, the seat 2 runs on the inside of the tubular housing main part 6. As a result, the clear cross section of the flow path AB in the region of the seat 2, viewed in the direction of flow, is somewhat smaller than above and below the seat 2. In order to avoid this, In a non-illustrated embodiment of the odor trap, the circumferential half of the tubular main part 6 opposite the housing extension 7 is provided with a bulge, and the housing extension 7 is designed to be wider than the bulge, with one circumferential half of the seat in the bulge and the other circumferential half below the lower edge the jacket half of the tubular housing main part designated 13 in FIGS. 1 and 3 is arranged. The bulge is to be dimensioned below the seat so that the pivoting of the flap 1 is guaranteed. This makes it possible to use a seat whose clear opening, as seen in the flow direction A-B, matches or is even larger than the clear cross section of the tubular housing main part 6.

Wenn eine geringfügige Verkleinerung des Strömungsquerschnitts im Bereich des Sitzes 2 in Kauf genommen werden kann, genügt es, den Sitz nur in Richtung quer zur Klappenschwenkachse 4 grösser auszuführen, und die Breite des Gehäuseansatzes 7 beizubehalten. Der Sitz ist dabei an seinem dem Gehäuseansatz 7 gegenüberliegenden, etwa halben Umfang in der Ausbuchtung und dieser gegenüber am unteren Rand des in Fig. 1 und 2 mit 13 bezeichneten Randes der oberen Mantelumfangshälfte anzuordnen, er ragt nur an seinen einander parallel zur Klappenschwenkachse 4 gegenüberliegenden Teilen in den Strömungsweg hinein.If a slight reduction in the flow cross-section in the area of the seat 2 can be accepted, it is sufficient to make the seat larger only in the direction transverse to the flap pivot axis 4 and to maintain the width of the housing extension 7. The seat is opposed at its the housing neck 7, approximately half the circumference in the bulge and facing against the bottom of the arranging in Fig. 1 and 2 with 13 designated edge of the upper casing half of the periphery, it extends only at its overlap pivot axis parallel to each other to K 4 opposite parts into the flow path.
