Abstract

A waste water outlet (A) has a side outlet (5) with an odour lock at a pre-determined height. The odour lock has two horizontal odour blocks (G1, G2) at different heights (h1, h2), each located above a lower threshold (12). The two blocks combine to define the overall lock height.

Description

Die Erfindung betrifft einen Abwasserablauf der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The invention relates to a wastewater drain specified in the preamble of claim 1. Art.

Bei einem aus GB 205 879 A bekannten Abwasserablauf ergibt sich die vorbestimmte Geruchverschluss-Höhe aus zwei Teil-Geruchverschluss-Höhen zweier getrennt wirkender Geruchverschlüsse. Da sich die Teil-Geruchverschluss-Höhen nicht überlappen, sondern zwischen ihnen ein beträchtlicher Hochabstand vorliegt, baut der Abwasserablauf unzweckmäßig hoch.In a wastewater discharge known from GB 205 879 A, the predetermined odor trap height results from two partial odor trap heights of two separately acting odor traps. Since the partial odor trap heights do not overlap but there is a considerable distance between them, the wastewater drain builds up inappropriately.

Bei einem aus EP 0 081 038 A bekannten Abwasserablauf wird die vorbestimmte Geruchverschluss-Höhe durchgehend zwischen der Innenwand eines in den Ablaufbehälter eingesetzten Topfes und einer von oben mittig in den Topf nach unten greifenden Schürze definiert. Aufgrund der oberhalb und unterhalb der vorbestimmten, in einem durchgehenden Geruchverschluss-Höhe erforderlichen Durchströmquerschnitte baut der Abwasserablauf unzweckmäßig hoch.In a waste water drain known from EP 0 081 038 A, the predetermined odor trap height is defined continuously between the inner wall of a pot inserted into the drain tank and an apron which extends downwards from above into the pot. Due to the above and below the predetermined, required in a continuous odor trap flow cross-sections of the wastewater drain is inconveniently high.

Bei einem aus EP 0 795 652 A bekannten Abwasserablauf mit Ölsperrfunktion wird die Geruchverschluss-Höhe durchgehend zwischen der Innenwand eines in den Ablaufbehälter eingesetzten Topfes, der mit seinem oberen Rand eine Überlaufschwelle definiert, und der Außenwand eines weiteren, von oben eingesteckten, eine bodenseitige Durchgangsöffnung bildenden Topf definiert. Aufgrund der oberhalb und unterhalb der Grenzen der vorbestimmten durchgehenden Geruchverschluss-Höhe erforderlichen Durchgangsquerschnitte baut der Abwasserablauf unzweckmäßig hoch.In a known from EP 0 795 652 A wastewater drain with oil barrier function, the odor trap height is continuously between the inner wall of a pot inserted into the drain tank, which defines an overflow threshold with its upper edge, and the outer wall of another, inserted from above, a bottom-side through hole defining pot. Due to the above and below the limits of the predetermined continuous odor trap height required passage cross-sections, the wastewater drain builds up inconveniently high.

Ein aus DE 295 17 550 U bekannter Abwasserablauf enthält die Geruchverschluss-Vorrichtung, um einen Rückstrom von Gerüchen oder Kanalgasen zu unterbinden. Typische Einsatzfälle sind im Badezimmer, im Keller, in Küchen oder ähnlichen Nassbereichen. In der Geruchverschtussvorrichtung wird die vorbestimmte Geruchverschluss-Höhe zwischen einer Topf-Innenwand und einem Tauchrohr durchgehend definiert. Die durchgehende Geruchverschlusshöhe bedingt jedoch eine bestimmte Bauhöhe der Geruchverschluss-Vorrichtung. In einem solchen Abwasserablauf sind jedoch oberhalb und unterhalb der Geruchverschluss-Vorrichtung bestimmte Durchströmquerschnitts-Höhen erforderlich. Da in modemen Gebäuden die Böden oder Estrichkonstruktionen relativ dünn sind oder nur geringe Einbautiefen für einen Abwasserablauf zulassen, lässt sich oftmals der Abwasserablauf nicht installieren. Es besteht deshalb Bedarf, die Bauhöhe der Abwasserabläufe mit Geruchverschluss so gering wie möglich zu halten, wobei jedoch die vorbestimmte Geruchverschluss-Höhe, beispielsweise 50 mm, gegeben sein muss.A known from DE 295 17 550 U wastewater drain contains the odor trap device to prevent a backflow of odors or channel gases. Typical applications are in the bathroom, in the basement, in kitchens or similar wet areas. In the scenting device, the predetermined odor trap height becomes defined continuously between a pot inner wall and a dip tube. The continuous odor trap height, however, requires a certain height of the odor trap device. In such a wastewater drain, however, certain flow cross-section heights above and below the odor trap device are required. Since in modern buildings the floors or screed constructions are relatively thin or allow only shallow installation depths for a wastewater drain, often the wastewater drain can not be installed. There is therefore a need to keep the height of the waste water drains with odor trap as low as possible, but the predetermined odor trap height, for example, 50 mm, must be given.

Der Erfindung liegt die Aufgabe zugrunde, einen Abwasserablauf bzw. eine Geruchverschluss-Vorrichtung der eingangs genannten Art mit verringerter Bauhöhe anzugeben.The invention has for its object to provide a waste water drain or odor trap device of the type mentioned with reduced height.

Die gestellte Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.The stated object is achieved with the features of claim 1.

Mit zwei Geruchverschlüssen, deren jeder nur eine wirksame Teil-Geruchverschluss-Höhe kleiner als die vorbestimmte Geruchverschluss-Höhe definiert, und die in Horizontalrichtung mittelbar oder unmittelbar durch die Unterströmschwelle separiert sind, lässt sich trotz der erforderlichen Durchströmquerschnitte oberhalb und unterhalb der Geruchverschluss-Vorrichtung die Bauhöhe des Abwasserablaufs bzw. der Geruchverschluss-Vorrichtung erheblich reduzieren, denn die Durchströmquerschnitts-Höhen oberhalb und unterhalb der Geruchverschluss-Vorrichtung addieren sich nur zur wirksamen Teil-Geruchverschluss-Höhe eines Geruchverschlusses hinzu, während sich die andere Teil-Geruchverschluss-Höhe auf die Bauhöhe nicht mehr auswirkt. Es lässt sich auf diese Weise eine sehr niedrig bauende Geruchverschluss-Vorrichtung bzw. ein sehr niedrig bauender Abwasserablauf schaffen, um mit Einbausituationen mit geringer Einbautiefe zurecht zu kommen. Zweckmäßig ist der eine Geruchverschluss ein Glocken-Geruchverschluss und ein weiterer ein Tauchwand-Geruchverschluss. Speziell der Tauchwand-Geruchverschluss beansprucht in Horizontalrichtung des Abwasserablaufs wenig Bauraum im Vergleich zum Glocken-Geruchverschluss. Es wäre aber auch denkbar, zwei Glocken-Geruchverschlüsse nebeneinanderliegend zu kombinieren, um die vorbestimmte Geruchverschlusshöhe trotz verringerter Bauhöhe zu gewährleisten. Herstellungstechnisch und strömungstechnisch günstig weist der erste Glocken-Geruchverschluss eine von der Unterströmschwelle aufsteigende, oben offene Steigwand und eine über die Steigwand außen nach unten greifende Glockenwand auf, und der andere Geruchverschluss eine, vorzugsweise vor der Ablauföffnung, nach unten bis zur Unterströmschwelle führende Tauchwand und eine gegenüber der Unterströmschwelle hochgesetzte Überlaufschwelle, vorzugsweise in die Ablauföffnung. Der Zulauf in den Ablaufbehälter erfolgt entweder von der Seite und/oder von oben, wobei das Abwasser zunächst den Glocken-Geruchverschluss durchsetzt und erst stromab der Unterströmschwelle den anderen Geruchverschluss. Dieses Konzept gestattet es auch, große Durchströmquerschnitte oberhalb und unterhalb der Geruchverschluss-Vorrichtung vorzusehen.With two odor traps, each of which defines only an effective partial odor trap height less than the predetermined odor trap height, and which are separated in the horizontal direction directly or indirectly by the underflow threshold, despite the required flow cross sections above and below the odor trap device Reduce the height of the wastewater drain or the odor trap device considerably, because the flow cross-section heights above and below the odor trap device add up only to the effective partial odor trap height of an odor trap, while the other partial odor trap height to the height no longer works. It can be created in this way a very low-built odor trap device or a very low-build wastewater drain to cope with installation situations with low installation depth. Suitably, one odor trap is a bell odor trap and another is a dip trap trap. Especially the baffle odor trap claimed in the horizontal direction of the wastewater drain little space compared to the bell odor trap. It would also be conceivable, two bells-odor closures adjacent to each other combine to ensure the predetermined odor trap height despite reduced height. In terms of manufacturing technology and flow, the first bells odor trap has a rising from the Unterströmschwelle, open-top wall and a climbing wall on the outside down-reaching bell wall, and the other odor trap one, preferably in front of the drain opening, down to Unterströmschwelle leading baffle and an overflow threshold raised above the underflow threshold, preferably into the discharge opening. The inflow into the drainage tank takes place either from the side and / or from above, wherein the wastewater first passes through the bell trap and only the other odor trap downstream of the underflow threshold. This concept also makes it possible to provide large flow cross sections above and below the odor trap device.

Die wirksame Teil-Geruchverschluss-Höhe des ersten Glocken-Geruchverschlusses wird zwischen dem oberen Ende der Steigwand und dem unteren Ende der Glockenwand definiert, während die wirksame Teil-Geruchverschluss-Höhe des anderen Geruchverschlusses zwischen dem unteren Ende der Tauchwand an der Unterströmschwelle und der Überlaufschwelle definiert wird. Die beiden Teil-Geruchverschluss-Höhen ergeben miteinander die vorbestimmte Geruchverschluss-Höhe der Geruchverschluss-Vorrichtung, wobei die Teil-Geruchverschluss-Höhe, die in die Bauhöhe des Abwasserablaufs bzw. der Geruchverschluss-Vorrichtung entscheidend eingeht, natürlich so niedrig wie möglich gewählt wird. Allerdings spielen hier die geometrischen Verhältnisse im Abwasserablauf eine Rolle, so dass im Regelfall die wirksame Teil-Geruchverschluss-Höhe des Glocken-Geruchverschlusses größer sein kann als die des anderen Geruchverschlusses.The effective partial odor trap height of the first bell odor trap is defined between the upper end of the riser wall and the lower end of the bell wall, while the effective partial odor trap height of the other odor trap is between the lower end of the dip wall at the underflow threshold and the overflow threshold is defined. The two partial odor trap heights together give the predetermined odor trap height of the odor trap device, wherein the partial odor trap height, which decisively enters into the height of the waste water drain or the odor trap device, of course, is chosen as low as possible. However, the geometric conditions in the wastewater drain play a role here, so that as a rule the effective partial odor trap height of the bell odor trap can be greater than that of the other odor trap.

Um gleichförmige Strömungsverhältnisse zu erzielen, kann die Unterströmschwelle die als zweckmäßig rohrförmige ausgebildete Steigwand außen vollständig umgeben. Der Tauchwand-Geruchverschluss ist stromab der Unterströmschwelle in Strömungsrichtung zur Ablauföffnung, vorzugsweise direkt bei der Ablauföffnung, platziert.In order to achieve uniform flow conditions, the Unterströmschwelle can completely surround the designed as suitably tubular riser wall outside. The baffle odor trap is placed downstream of the underflow sill in the flow direction to the drain opening, preferably directly at the drain opening.

Herstellungstechnisch günstig sind die Steigwand-, die Unterströmschwelle und die Tauchwand in einem einstückigen Formteil enthalten, der in einem Dichtsitz des Ablaufbehälters herausnehmbar festgelegt wird. Die Glocke des Glocken-Geruchverschlusses wird dann beispielsweise von dem Formteil getragen.In terms of manufacturing technology, the riser wall, the underflow threshold and the baffle wall are contained in a one-piece molding which is located in a sealing seat of the drainage tank is determined to be removable. The bell of the bells odor trap is then carried by the molded part, for example.

Anhand der Zeichnung wird eine Ausführungsform des Erfindungsgegenstandes erläutert. Die Fig. 1 ist ein Vertikalschnitt einer Ausführungsform eines Abwasserablaufs.Reference to the drawings, an embodiment of the subject invention will be explained. Fig. 1 is a vertical section of an embodiment of a wastewater drainage.

Der in Fig. 1 gezeigte Abwasserablauf A ist beispielsweise ein Keller-, Bad- oder Deckenablauf, der vorwiegend im Boden eines Innenraums installiert wird und deshalb gegen zurückströmende Gerüche oder Kanalgase mit einer Geruchverschluss-Vorrichtung V ausgestattet ist. In der gezeigten Ausführungsform ist die Geruchverschluss-Vorrichtung V zwischen einem Zulauf Z und einem Ablauf X in einem Ablaufbehälter 1 wirksam, der gegebenenfalls auch einen oberseitigen Einlauf besitzt. Abzusperrende Gerüche stammen aus dem Ablauf X.The wastewater drain A shown in Fig. 1 is for example a basement, bath or ceiling drain, which is mainly installed in the bottom of an interior and is therefore equipped against backflowing odors or duct gases with a odor trap device V. In the embodiment shown, the odor-trap device V between an inlet Z and a drain X is effective in a drain tank 1, which optionally also has an upper-side inlet. Locked odors come from the expiration X.

Der Ablaufbehälter 1 ist annähernd topfförmig gestaltet, besitzt eine ebene Bodenwand 2, eine umlaufende Seitenwand 3 mit einer oberen Dichtfassung 4 für einen Deckel, und wird entweder durch einen Deckel oder einen Rost verschlossen. In der Seitenwand 3 ist wenigstens eine Ablauföffnung 5 und wenigstens eine Zulauföffnung 8 geformt. Bei der Ablauföffnung 5 ist in der Seitenwand 3 eine Überlaufschwelle 6, z.B. mit geradem Verlauf senkrecht zur Zeichnungsebene, geformt, beispielsweise an einer tieferen Position des Behälters 1 als die Unterkante der Zulauföffnung 8. Die Überlaufschwelle 6 könnte alternativ auch im Inneren des Ablaufbehälters 1 vorgesehen sein.The drain container 1 is designed approximately pot-shaped, has a flat bottom wall 2, a circumferential side wall 3 with an upper sealing socket 4 for a lid, and is closed by either a lid or a grate. In the side wall 3, at least one drain opening 5 and at least one inlet opening 8 is formed. In the discharge opening 5, an overflow threshold 6, for example with a straight course perpendicular to the plane of the drawing, is formed in the side wall 3, for example at a lower position of the container 1 than the lower edge of the feed opening 8. The overflow threshold 6 could alternatively also be provided inside the drainage container 1 be.

Die Geruchverschluss-Vorrichtung V weist zumindest einen einstückigen Formteil F und eine aufgesetzte Glocke 15 auf. Der Formteil F ist mit einem Dichtrand 14 in einem entlang der Behälterinnenwand z.B. schräg verlaufenden Dichtsitz 7 herausnehmbar, jedoch dicht gehaltert. Die Glocke 15 ist auf den Formteil aufgesetzt und mit einer Fassung 19 und Stützstegen 21 abgestützt. Eine Deckwand 20 der Glocke 15 erstreckt sich bis zur Zulauföffnung 8.The odor trap device V has at least one integral molded part F and an attached bell 15. The molded part F is provided with a sealing edge 14 in a container inner wall, e.g. obliquely sealing seat 7 removable, but tightly supported. The bell 15 is placed on the molding and supported with a socket 19 and 21 supporting webs. A top wall 20 of the bell 15 extends to the inlet opening eighth

Die Geruchverschluss-Vorrichtung V umfasst bei der gezeigten Ausführungsform zwei Geruchverschlüsse, nämlich einen Glockengeruch-Verschluss G1 und einen Tauchwand-Geruchverschluss G2, deren jeder eine wirksame Teil-Geruchverschlusshöhe h1 bzw. h2 definiert. Die Geruchverschluss-Vorrichtung V könnte insgesamt fest eingebaut sein. Der herausnehmbare Formteil F erlaubt jedoch eine leichte Säuberung.The odor trap device V in the embodiment shown comprises two odor traps, namely a bell odor closure G1 and a baffle trap G2, each of which defines an effective partial odor trap height h1 and h2, respectively. The odor trap device V could be permanently installed as a whole. However, the removable molding F allows easy cleaning.

Der Glocken-Geruchverschluss G1 umfasst eine Steigwand 9 mit einer oberen Öffnung 10, wobei die Steigwand beispielsweise als Rohrwand ausgebildet ist und sich mit einem gebogenen, umlaufenden Bereich nach unten bis zu einer Unterströmschwelle 12 erstreckt. An die Unterströmschwelle 12 schließt sich eine nach oben bis zu dem Dichtrand 14 verlaufende Tauchwand 13 des Tauchwand-Geruchverschlusses G2 an. Diese Tauchwand 13 umfasst eine Glockenwand 16 und erstreckt sich in Fig. 1 nach links schräg abfallend bis zum Dichtsitz 7 unterhalb der Mündung der Zulauföffnung 8. Die Glocke 15 hat eine ebene Deckwand 18 und die von dieser gerundet herabhängende Glockenwand 16, die mit einem unteren horizontalen Ende 17 im Abstand oberhalb der Unterströmschwelle 12 ausläuft. Die Teil-Geruchverschluss-Höhe h1 des Glocken-Geruchverschlusses G1 wird zwischen dem oberen Ende 10 der Steigwand 9 und dem unteren Ende 17 der Glockenwand 16 definiert.The bell scent closure G1 comprises a riser wall 9 with an upper opening 10, wherein the riser wall is formed, for example, as a tube wall and extends with a curved, circumferential region down to a Unterströmschwelle 12. At the Unterströmschwelle 12 is followed by an upwardly extending to the sealing edge 14 baffle 13 of the dip wall odor trap G2. This baffle 13 comprises a bell wall 16 and extends in Fig. 1 to the left obliquely sloping to the sealing seat 7 below the mouth of the inlet opening 8. The bell 15 has a flat top wall 18 and rounded by this hanging bell wall 16, with a lower horizontal end 17 at a distance above the Unterströmschwelle 12 expires. The part odor trap height h1 of the bell scent G1 is between the upper end 10 of the riser wall 9 and the lower end 17 of the bell wall 16 defined.

Der Tauchwand-Geruchverschluss G2 wird definiert durch die Tauchwand 13, die sich bis zur Unterströmschwelle 12 und im Abstand vor der Mündung der Ablauföffnung 5 erstreckt und dem Abschnitt der Seitenwand 3, der nach oben bis zur Überlaufschwelle 6 reicht. Zwischen der Überlaufschwelle 6 und der Unterströmschwelle 12 wird die wirksame Teil-Geruchverschluss-Höhe h2 des Tauchwand-Geruchverschlusses G2 definiert.The baffle odor trap G2 is defined by the baffle 13, which extends to Unterstromschwelle 12 and at a distance from the mouth of the drain opening 5 and the portion of the side wall 3, which extends up to the overflow threshold 6. Between the overflow threshold 6 and the underflow threshold 12, the effective partial odor trap height h2 of the baffle odor trap G2 is defined.

Oberhalb des Endes 10 der Steigwand 9 ist unterhalb der Deckwand 18 ein oberer Durchströmquerschnitt 22 vorgesehen, während unterhalb des Endes 17 ein weiterer Durchströmquerschnitt 23 gebildet wird. Unterhalb der Unterströmschwelle 12 wird ein weiterer Durchströmquerschnitt 24 begrenzt, über welchen der Innenraum innerhalb der Steigwand 9 mit dem Tauchwand-Geruchverschluss G2 in Strömungsverbindung ist.Above the end 10 of the riser wall 9, an upper flow cross-section 22 is provided below the top wall 18, while below the end 17, a further flow cross-section 23 is formed. Below the underflow threshold 12, a further flow cross section 24 is delimited, via which the interior space within the riser wall 9 is in flow connection with the dip wall odor trap G2.

Die Summe der wirksamen Teil-Geruchverschluss-Höhen h1 und h2 ergibt zumindest die vorbestimmte Geruchverschluss-Höhe der Geruchverschluss-Vorrichtung V. Da die wirksame Teil-Geruchverschluss-Höhe h1 um die wirksame Teil-Geruchverschluss-Höhe h1 geringer ist als die vorbestimmte Geruchverschluss-Höhe, resultiert die Bauhöhe des Ablaufbehälters 1 bzw. der Geruchverschluss-Vorrichtung V mit den notwendigen oberen und unteren Durchströmquerschnitten 22, 24 in einer erheblich geringeren Bauhöhe, als sie sich ergäbe, wenn der Glocken-Geruchverschluss G1 allein die ganze vorbestimmte Geruchverschluss-Höhe definieren würde.The sum of the effective partial odor trap heights h1 and h2 gives at least the predetermined odor trap height of the odor trap device V. Since the effective partial odor trap height h1 is less than the predetermined partial odor trap height h1 than the predetermined odor trap height h1. Height, resulting in the height of the drain tank 1 and the odor trap device V with the necessary upper and lower flow areas 22, 24 in a significantly lower height, as it would result if the bell odor trap G1 alone define the whole predetermined odor trap height would.

Bei einer nicht gezeigten Ausführungsform könnten auch zwei Glocken-Geruchverschlüsse kombiniert werden, oder zwei Tauchwand-Geruchverschlüsse. Bei der gezeigten Ausführungsform beträgt das Verhältnis der wirksamen Teil-Geruchverschluss-Höhen ca. 2 : 1; dieses Verhältnis kann aber wahlweise variiert werden.In an embodiment not shown, two bells odor traps could also be combined, or two baffle odor traps. In the embodiment shown, the ratio of effective partial odor trap heights is about 2: 1; but this ratio can be varied as desired.

Aus dem Zulauf Z kommendes Abwasser strömt um die Glockenwand 16 und durch den Durchströmquerschnitt 23 ins innere der Glockenwand 16 ein, überströmt dann das Ende 10 und fällt auf die Bodenwand 2, ehe es durch den Durchströmquerschnitt 24 und über die Überlaufschwelle 6 in den Ablauf X gelangt. Hört der Abwasserstrom auf, dann bleibt zwischen der Glockenwand 16 und der Steigwand 9 in dem dort gebildeten Raum eine Wassersäule mit der Höhe h1 stehen, während zwischen der Tauchwand 13 und der Überlaufschwelle 16 eine Wassersäule mit der Höhe h2 stehen bleibt. Diese Wassersäulen bewirken den Geruchverschluss mit zumindest der vorbestimmten Geruchverschluss-Höhe h1 + h2.Waste water coming from the inlet Z flows around the bell wall 16 and through the flow cross-section 23 into the interior of the bell wall 16, then flows over it the end 10 and falls on the bottom wall 2, before it passes through the flow area 24 and the overflow threshold 6 in the sequence X. If the sewage stream stops, then a water column with the height h1 remains between the bell wall 16 and the riser 9 in the space formed there, while a water column with the height h2 remains between the baffle 13 and the overflow threshold 16. These water columns cause the odor trap with at least the predetermined odor trap height h1 + h2.

Die Bauhöhe des Abwasserablaufs A beträgt nur etwas mehr als das Doppelte der Höhe h1. Die Bauhöhe der Geruchverschluss-Vorrichtung V beträgt bei der gezeigten Ausführungsform weniger als das Doppelte der Höhe h1.The height of the waste water drain A is only slightly more than twice the height h1. The height of the odor trap device V is less than twice the height h1 in the embodiment shown.
