Description

Die Erfindung betrifft eine Vorrichtung zum Zurückhalten aufsteigender Warmluft in rohrförmigen Dachdurchbrüchen und aufsteigender Kanalgase in Regenfallrohren gemäss Oberbegriff des Patentanspruchs 1.The invention relates to a device for retaining ascending warm air in tubular roof openings and ascending sewer gases in downpipes according to Preamble of claim 1.

Sanitärentlüftungsrohre und Flachdachabläufe werden in der Regel offen und ohne Abdeckhauben vom erwärmten Innenraum nach aussen geführt. Das Innenraumklima erwärmt die Luftsäule im Rohrinnern durch Wärmetransmission und lässt diese aufsteigen und in die Umgebung entweichen. Der Energieverlust eines Dunstrohres mit einem Durchmesser von 110 mm während einer Heizperiode beträgt für ein Einfamilienhaus zwischen 50-100 Liter Heizöläquivalente.Sanitary ventilation pipes and flat roof drains are used in the Normally open and without covers from the heated interior led to the outside. The interior climate heats the Air column in the tube interior by heat transmission and leaves they ascend and escape into the environment. Of the Energy loss of a vent pipe with a diameter of 110 mm during a heating period is for one Detached house between 50-100 liters of heating oil equivalents.

Mit der offenen Fallstrangführung und einem Dunstrohr über Dach werden Unterdruck- oder Überdruckzustände, wie sie in Kanalisationssystemen auftreten, verhindert. Unterdruck würde die Siphonierung behindern (den Sperrwasserstand herausziehen) und Kanalgase könnten mit Überdruck in den Sanitärraum geraten.With the open case strand guide and a vent pipe over Roof will become vacuum or overpressure conditions as they are in Sewer systems occur prevented. vacuum would hinder the siphoning (the water level pull out) and channel gases could with overpressure in the Sanitary room advised.

Auch bei durch die Dachisolation geführten Dachgullys hat man das thermische Leck bis jetzt unterschätzt. Ein solches Rohr kann pro Heizperiode Transmissionsverluste von bis zu 100-140 Liter Heizöläquivalente verursachen.Also has led through the roof insulation roof outlets to underestimate the thermal leak so far. One such tube can transmission losses per heating period of up to 100-140 liters of heating oil equivalents.

Dachgullys werden in der Regel offen nur mit einem Laubfanggitter versehen montiert. Das Innenraumklima erwärmt die Luftsäule im Rohrinnern durch Wärmetransmission und lässt diese aufsteigen und in die Umgebung entweichen. Das Regenfallrohr penetriert die Dachisolation wie ein Kamin und verbindet das Innenraumklima mit der Aussenluft. Besonders mit der zunehmenden Isolationsstärke wird das Energieverlust-Potential grösser. Speziell die weitverbreiteten Unterdruckentwässerungssysteme ermöglichen das weitgehend gefällslose Verlegen der Regenfallleitungen im Gebäudeinnern. Die warmseitige Rohrabwicklung wird dadurch vergrössert und damit wird auch der Transmissionsverlust entsprechend grösser. Solche Leitungen werden standardmässig nur mit minimaler Schwitzwasserisolation in einer Dicke von 1-2 cm versehen. Roof gullies are usually open only with one Laubfanggitter fitted mounted. The interior climate heats the air column inside the tube Heat transmission and lets rise and in the Escape environment. The downpipe penetrates the Roof insulation like a fireplace and connects that Indoor climate with the outside air. Especially with the Increasing insulation strength becomes the energy loss potential greater. Especially the widespread Vacuum drainage systems make this possible to a large extent precipitation free laying of rainwater pipes in Building interior. The warm side pipe development is characterized increases and thus also the transmission loss correspondingly larger. Such lines will be standard only with minimal condensation in a thickness of 1-2 cm provided.

Seit ca. dreissig Jahren sind Unterdruckventile als Ersatz für Sanitärdunstrohre im Einsatz. Diese Ventile werden warmwasserseitig auf die Fallstränge aufgesetzt. Bei Unterdruck im Fallstrang öffnet sich eine Klappe und Raumluft wird eingesaugt. Diese Ventile sind Einwegventile, weil sie nur den Unterdruck entspannen und sich sofort wieder verschliessen. Überdruck im Kanalisationssystem kann nicht mehr entweichen. Aus diesem Grunde sind sie nicht überall zugelassen. In gewissen Fällen muss deshalb die Kanalisation über Dach entlüftet werden.
Geruchsbelästigung durch hochsteigende Kanalisations-Entlüftungen aus Dunstrohren in der Nähe von Terrassen, Balkonen oder Dachgaubenfenster etc. sind an der Tagesordnung. Die nachträgliche Sanierung ist mit grossem Aufwand verbunden.
Bekannt ist auch der relativ grosse Aufwand der Kanalgasabtrennung bei Regenwasser-Fallrohranschlüssen an die Mischkanalisation. Es müssen zu diesem Zweck im Sockelbereich der Regenfallrohre siphonierte Schächte eingebaut werden. Bei mangelhafter Wartung können diese verstopfen. Mit diesem Schacht werden die Kanalgase zurückgehalten. Die aggressiven Kanalgase würden neben den üblen Gerüchen auf die metallenen Fallrohre korrosiv wirken. For about thirty years vacuum valves are used as a replacement for plumbing pipes. These valves are placed on the fall lines on the warm water side. At negative pressure in the casing, a flap opens and room air is sucked in. These valves are one-way valves because they only relax the vacuum and close immediately. Overpressure in the sewer system can no longer escape. That's why they are not allowed everywhere. In certain cases, the sewage system must therefore be vented through the roof.
Odor nuisance caused by high-rising sewerage vents from fume pipes near terraces, balconies or dormer windows, etc. are the order of the day. The subsequent renovation is associated with great effort.
Also known is the relatively large expense of sewer gas separation in rainwater downcomers to the mixing sewer. It must be installed for this purpose in the base area of the rainwater pipes siphonierte shafts. In the case of poor maintenance, these can become clogged. With this shaft, the channel gases are retained. The aggressive channel gases would be corrosive to the bad smells on the metal downpipes.

Die Erfindung hat sich daher zur Aufgabe gemacht, diese Geruchsbelästigungen, aggressiven Kanalgase und/oder den unnötigen Energieabfluss zu unterbinden.The invention has therefore set itself the task of this Odor nuisance, aggressive duct gases and / or the to prevent unnecessary energy drainage.

Diese Aufgabe wird mit einer Vorrichtung gemäss den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with a device according to the Characteristics of claim 1 solved.

Die Erfindung ermöglicht es, dass die Verschlussklappe durch die Ausformung der Schlitze und die Materialbeweglichkeit der Membrane sowohl das Durchfliessen des Wassers von oben zulässt als auch nach Beendigung des Niederschlages sofort in die Ausgangslage zurückklappt. Bei wenig Wasserfluss öffnet sich die Verschlussklappe wenig, bei grossem Wasseranfall wird die Verschlussklappe durch den Fluidfluss vollständig geöffnet.
In geschlossenem Zustand bewirkt die Verschlussklappe einen Warmluftanstau. Die Warmluft bildet unter der Verschlussklappe einen Warmluftpfropfen, der den ständigen Energiefluss durch die aufsteigende Warmluft nach aussen effizient unterbindet. Der Energieverlust reduziert sich auf die zwischen der Kaltseite der Verschlussklappe und dem warmseitigen Warmluftpfropfen an der Verschlussklappe austretende Wärme. Der Rohrquerschnittsverlust ist dann vernachlässigbar. Der Warmluftstau verhindert das Einfrieren der Verschlussklappe im Winter. The invention makes it possible that the closure flap by the formation of the slots and the material mobility of the membrane allows both the flow of water from above as well as after completion of the precipitate immediately folds back into the starting position. If the flow of water is low, the flap does not open very much. In the event of a large amount of water, the flap is completely opened by the fluid flow.
When closed, the flap causes a hot air accumulation. The hot air forms under the flap a hot air plug, which efficiently prevents the constant flow of energy through the rising warm air to the outside. The energy loss is reduced to the heat exiting between the cold side of the shutter and the hot side hot air plug on the shutter. The pipe cross-section loss is then negligible. Hot air storage prevents the shutter from freezing in winter.

Wird die Verschlussklappe in Sanitärdunstrohre eingebaut, kann jederzeit Überdruck nach aussen entweichen, weil die aufsteigenden Gase die Verschlussklappe nach oben drücken und der Druck entweichen kann. Nach dem Druckausgleich, der nach wenigen Sekunden hergestellt ist, schliesst sich die Verschlussklappe wieder. Wenn im Sanitärfallrohr durch abfliessendes Wasser Unterdruck entsteht, öffnet sich die Verschlussklappe, indem die Klappensegmente sich nach unten verformen und den Querschnitt sternförmig öffnen. Die Verschlussklappe kann mit herkömmlichen Unterdruckventilen kombiniert eingesetzt werden.If the flap is installed in plumbing tubes, can escape pressure at any time to the outside, because the Ascending gases push the flap upwards and the pressure can escape. After pressure equalization, which is made after a few seconds, closes the flap again. When in the sanitary downpipe through draining water creates negative pressure, the opens Closing flap by the flap segments after deform below and open the cross-section in a star shape. The flap can be with conventional Vacuum valves are used in combination.

Am oberen Ende des Fallrohrs 17 ist schematisch und mit Bezugszeichen 25 angegeben ein Gully mit einem Hut 9 dargestellt. Unterhalb der Verschlussklappe 11 ist wieder mit Bezugszeichen 13 ein Warmluftpfropfen mittels Punkten dargestellt. Die Warmluft gelangt durch Wärmetransmission, dargestellt durch die Pfeile 23, aus dem Gebäudeinnern durch die Wandung des Fallrohres 17 in letzteres und von dort in die Umgebung. Der Gully 25 kann oben mit einem Laubfanggitter versehen sein.FIG. 2 shows an analogous arrangement of a Closure flap 11 in a rainwater downpipe 17, short Downpipe 17, mounted on a flat roof 19 with a Isolation 7 and a roofing 21.

In der Ausgestaltung der Erfindung gemäss Figur 8 ist die Verschlussklappe 11 an der Innenwand der Abdeckhaube eines Gully 25 in Gestalt von Lappen 29 ausgebildet. Die Lappen 29' sind an deren Oberkante gehalten und decken die darunterliegenden Öffnungen 35 vollständig ab, solange auf der Innenseite des Gully durch den Warmluftpfropfen 13 ein Überdruck vorherrscht. Wasser, das von der Aussenseite durch die Öffnungen 35 eintritt, hebt die Lappen 29' leicht ab. Allerdings werden die Lappen 29 nur so weit abgehoben, damit das Wasser durchtreten kann, nicht aber warme Luft aus dem Innern nach aussen fliessen kann. Die Lappen können an einem Ring 33, wie er bereits aus anderen Erfindungsbeispielen bekannt ist, befestigt sein.In the embodiment of the invention according to Figure 8 is the Closure flap 11 on the inner wall of the cover of a Gully 25 formed in the form of lobes 29. The rags 29 'are held at the upper edge and cover the underlying openings 35 completely off, as long as the inside of the gully through the hot air plug 13 a Overpressure prevails. Water from the outside enters through the openings 35, lifts the tabs 29 ' slightly off. However, the lobes 29 are only so far lifted, so that the water can pass through, but not warm air can flow from the interior to the outside. The Rags can attach to a ring 33, as he already has from others Invention examples is known to be attached.

In der Ausgestaltung der Erfindung gemäss Figur 9 ist die Verschlussklappe 11 trichterförmig ausgebildet und trägt eine Kugel 41 aus einem leichten, aufschwimmbaren Material oder sie ist als Hohlkörper ausgebildet. Die Kugel 41 liegt auf der membranförmigen Verschlussklappe 11 und verschliesst die zentrale Öffnung 35, so dass keine warme Luft austreten kann. Von oben eintretendes Wasser sammelt sich peripher um die Kugel 41 und hebt diese leicht an, so dass das Wasser durch die Öffnung 35 abfliessen kann.In the embodiment of the invention according to Figure 9 is the Closure flap 11 funnel-shaped and carries a ball 41 made of a light, floatable material or it is designed as a hollow body. The ball 41 lies on the membrane-shaped flap 11 and closes the central opening 35, so no warm Air can escape. Water entering from above collects peripherally around the ball 41 and lifts it slightly, so that the water can flow through the opening 35.
