Description

Die Erfindung betrifft eine Einrichtung zum Verbinden zweier im Winkel zueinander verlaufender Abschnitte einer Luft-Abgas-Leitung.The invention relates to a device for connecting two sections running at an angle to each other Air off-gas line.

Luft-Abgas-Leitungen werden für raumluftunabhängige Verbrennungseinrichtungen verwendet, beispielsweise für Heizkessel, und zwar insbesondere für Brennwertgeräte. Dabei verbindet die Luft-Abgas-Leitung die Verbrennungseinrichtung mit dem Kaminkopf. Die innen liegende Abgasführung leitet das Abgas zum Kaminkopf, und die außen liegende Luftführung, die mit der Abgasführung einen Ringraum bildet, versorgt die Verbrennungeinrichtung mit aus der Atmosphäre angesaugter Verbrennungsluft.Air-exhaust gas lines are used for combustion devices that are independent of ambient air used, for example for boilers, especially for condensing boilers. there the air-exhaust pipe connects the combustion device with the chimney head. The internal exhaust gas routing guides the flue gas to the chimney head and the outside air duct, which forms an annulus with the exhaust gas duct supplies the Combustion device with suction from the atmosphere Combustion air.

Die Luft-Abgas-Leitung muß für regelmäßige Inspektionen zugänglich sein. Dabei muß der Kaminkehrer die Möglichkeit haben, sowohl die Luftführung als auch die Abgasführung zu inspizieren. Die Inspektion findet vorzugsweise an den Umlenkstellen der Luft-Abgas-Leitung statt.The air-exhaust pipe must be used for regular inspections be accessible. The chimney sweeper must have the option have both the air duct and the exhaust duct inspect. The inspection is preferably carried out at the deflection points the air-exhaust pipe instead.

Der Erfindung liegt die Aufgabe zugrunde, eine bequeme und dennoch zuverlässige Inspektion zu ermöglichen, und zwar auf platzsparende Weise.The invention has for its object a convenient and still enable reliable inspection, namely in a space-saving way.

Hierzu ist die Verbindugnseinrichtung nach der Erfindung versehen mit

  • einem der Abgasführung zugeordneten inneren Rohrbogen, der in rückwärtiger Fortsetzung eines seiner Arme einen Stutzen aufweist, welcher von einem abnehmbaren Deckel verschlossen ist, und
  • einem der Luftführung zugeordneten äußeren Rohrbogen, der den inneren Rohrbogen aufnimmt und in rückwärtiger Fortsetzung seiner beiden Arme eine Öffnung aufweist, die von einer abnehmbaren Kappe verschlossen ist, wobei die Öffnung des äußeren Rohrbogens in einer Ebene liegt, die geneigt zu den Achsen der beiden Arme des äußeren Rohrbogens verläuft.
For this purpose, the connection device according to the invention is provided with
  • an inner pipe bend assigned to the exhaust gas duct, which, in the rearward continuation of one of its arms, has a connecting piece which is closed by a removable cover, and
  • an outer pipe bend assigned to the air duct, which receives the inner pipe bend and, in the rearward continuation of its two arms, has an opening which is closed by a removable cap, the opening of the outer pipe bend lying in a plane which is inclined to the axes of the two arms of the outer pipe bend.

Zu Zwecken der Inspektion wird die Kappe des äußeren Rohrbogens abgenommen. Dadurch wird die schräg liegende Öffnung des äußeren Rohrbogens zugänglich. Sie eröffnet den direkten Einblick in beide im Winkel zueinander verlaufende Zweige der Luftführung. Außerdem wird der Deckel, der den Stutzen des inneren Rohrbogens verschließt, zugänglich. Er kann abgenommen werden und ermöglicht den direkten Einblick in denjenigen Zweig der Abgasführung, der die Fortsetzung des Stutzens bildet. In den im Winkel dazu verlaufenden Zweig der Abgasführung ist ohne weitere Hilfsmittel immer noch ein schräger Einblick möglich.For inspection purposes, the cap of the outer Pipe elbow removed. This creates the slanted opening accessible from the outer pipe bend. It opens the direct Insight into both at an angle to each other Air duct branches. In addition, the lid that the Socket of the inner pipe bend is closed, accessible. He can be removed and allows direct insight in the branch of the exhaust system, which is the continuation of the nozzle. In the at an angle to it Branch of exhaust gas routing is always without further aids still an angled look possible.

Von wesentlicher Bedeutung ist, daß das Einfügen des inneren Rohrbogens in den äußeren Rohrbogen'keinerlei Schwierigkeiten bereitet. Die schräg liegende Öffnung des äußeren Rohrbogens bietet die Möglichkeit, den inneren Rohrbogen in den äußeren Rohrbogen "einzudrehen". Der äußere Rohrbogen muß also nicht übermäßig groß dimensioniert sein, um ein Einsetzen des inneren Rohrbogens zu ermöglichen.It is essential that the insertion of the inner Elbows in the outer elbows have no difficulties prepares. The sloping opening of the outer Pipe bend offers the possibility of the inner pipe bend in "screw in" the outer elbow. The outer pipe bend So does not have to be excessively large to a To allow insertion of the inner pipe bend.

Die beiden Rohrbögen weisen jeweils ein Einsteckende und ein Muffenende auf, die den Einbau der Verbindungseinrichtung in die Luft-Abgas-Leitung ermöglichen. Die Einrichtung wird vorzugsweise an derjenigen Umlenkstelle eingebaut, an der der vom Kessel kommende vertikale Leitungsabschnitt in den zum Kamin führenden horizontalen Leitungsabschnitt umgelenkt wird. Dementsprechend sind die vertikal nach unten gerichteten Arme der Rohrbögen als Einsteckenden ausgebildet. Die anderen Arme, die vorzugsweise in einem Winkel von etwas mehr als 90° abstehen, sind als Muffenenden ausgebildet. Aufgrund des Gefälles kann Kondensat, das sich in der Abgasleitung niedergeschlagen hat, zum Kessel abgeleitet werden.The two pipe bends each have an insertion end and a sleeve end on the installation of the connector allow in the air-exhaust pipe. The facility is preferably installed at that deflection point the vertical pipe section coming from the boiler in redirected the horizontal line section leading to the chimney becomes. Accordingly, those are vertically downward Arms of the pipe bends are designed as insertion ends. The other arms, preferably at an angle of something protrude more than 90 ° are designed as socket ends. Due to the gradient, condensate can accumulate in the exhaust pipe has put down to the boiler.

Der Stutzen des inneren Rohrbogens liegt praktisch auf der Achse des Muffenendes des inneren Rohrbogens, ist allerdings auch geringfügig geneigt, um den Abfluß von Kondensat zu ermöglichen. Nach Abnahme des Deckels wird der direkte Blick in den horizontalen Zweig der Abgasführung freigegeben.The nozzle of the inner pipe bend is practically on the axis of the socket end of the inner pipe bend, however also slightly inclined to drain condensate to enable. After removing the cover, the direct View of the horizontal branch of the exhaust system released.

Auch die Kappen des äußeren Rohrbogens liegt im wesentlichen auf der Achse des Muffenendes des äußeren Rohrbogens. Nach Abnehmen der Kappe sind die ringförmigen Luftführungen in beiden Richtungen einsehbar.The caps of the outer pipe bend also lie essentially on the axis of the socket end of the outer pipe bend. After removing the cap, the ring-shaped air ducts are Visible in both directions.

Andere Anordnungen und Orientierungen der Verbindungseinrichtung sind ohne weiteres möglich. Beispielsweise kann die Einrichtung am Übergang zum vertikal im Kamin verlaufenden Leitungsabschnitt angeordnet werden. Auch kann der Winkel zwischen den Armen der Rohrbögen wesentlich deutlicher von 90° abweichen, als es für die Erzielung eines Gefälles für das Kondensat erforderlich ist.Other arrangements and orientations of the connection device are easily possible. For example the device at the transition to the vertical in the fireplace Line section are arranged. The angle can also between the arms of the pipe bends much more clearly deviate from 90 ° than it is for achieving a slope is required for the condensate.

Vorzugsweise verläuft die Ebene, in der die Öffnung des äußeren Rohrbogens liegt, senkrecht zu derjenigen Ebene, die von den Achsen der beiden Arme des äußeren Rohrbogens aufgespannt wird. Dabei ist es besonders vorteilhaft, daß die Ebene, in der die Öffnung des äußeren Rohrbogens liegt, mit den Achsen der beiden Arme des äußeren Rohrbogens gleich Winkel vorzugsweise von im wesentlichen 45° bildet. Die Öffnung liegt also symmetrisch zu beiden Armen des äußeren Rohrbogens.The plane in which the opening of the outer pipe bend is perpendicular to the plane that spanned by the axes of the two arms of the outer pipe bend becomes. It is particularly advantageous that the Plane in which the opening of the outer pipe bend lies with the axes of the two arms of the outer pipe bend Forms an angle preferably of substantially 45 °. The opening is therefore symmetrical to both arms of the outer Pipe bend.

Ein weiteres vorteilhaftes Merkmal besteht darin, daß die Kappe, die die Öffnung des äußeren Rohrbogens verschließt, eine rohrförmige, am Ende geschlossene rückwärtige Fortsetzung eines der Arme des äußeren Rohrbogens bildet. Dabei ist es besonders vorteilhaft, daß die Kappe den Stutzen des inneren Rohrbogens aufnimmt. Dies bietet optimale Einbau- und Montagebedingungen.Another advantageous feature is that the cap that closes the opening of the outer pipe bend, a tubular rear end closed Continuation of one of the arms of the outer pipe bend forms. It is particularly advantageous that the cap the nozzle of the inner pipe bend. This offers optimal Installation and assembly conditions.

Konstruktiv besonders günstig ist es, die Kappe auf einen Steg aufzustecken, der um den Rand der Öffnung des äußeren Rohrbogens herumläuft. Dabei wird zwischen die Kappe und den Steg vorzugsweise ein Dichtring eingelegt, der die Reibkraft zum Halten der Steckverbindung erzeugt. Der Steg weist eine umlaufende Nut auf, in die der Dichtring eingelegt wird. Er gelangt dann durch das Aufstecken der Kappe unter Pressung. Die Dichtfunktion des Ringes ist von sekundärer Bedeutung, da der äußere Rohrbogen und die Kappe Bestandteile der Luftführung sind.It is structurally particularly favorable to put the cap on one Pin the web around the edge of the opening of the outer Pipe bend runs around. It is between the cap and the web preferably inserted a sealing ring, the friction force generated to hold the connector. The bridge points a circumferential groove in which the sealing ring is inserted becomes. It then gets under by attaching the cap Pressing. The sealing function of the ring is secondary Meaning because of the outer elbow and the cap components the air flow.

In wesentlicher Weiterbildung der Erfindung wird vorgeschlagen, daß in den Stutzen des inneren Rohrbogens ein Strömungsleitelement eingesteckt ist, das die Abgasströmung aus dem einen Arm des inneren Rohrbogens in dessen anderen Arm umlenkt. Da der Stutzen des inneren Rohrbogens im Winkel, häufig im wesentlichen senkrecht zur Zuströmrichtung des Abgases liegt, würde die Abgasströmung ohne das Strömungsleitelement praktisch auf ein senkrechtes Hindernis prallen. Dies würde zu erheblichen Turbulenzen und folglich zu einem entsprechenden Druckverlust führen. Trotz der Inspektionsöffnung wirkt also der innere Rohrbogen wie ein glatter Rohrkrümmer. Die durch das Strömungsleitelement bewirkte Verminderung des Druckverlustes entspricht einer zusätzlichen Kaminhöhe bzw. Abgasleitungslänge von zirka drei bis zehn Metern, je nach Anwendungsfall.In an essential further development of the invention it is proposed that in the socket of the inner pipe bend Flow control element is inserted, the exhaust gas flow from one arm of the inner pipe bend in the other Arm deflected. Since the socket of the inner pipe bend is at an angle, often essentially perpendicular to the direction of inflow of the exhaust gas, the exhaust gas flow would be without the flow guide practically on a vertical obstacle plump. This would create significant turmoil and consequently lead to a corresponding pressure loss. Despite the inspection opening So the inner pipe bend acts like a smooth elbow. The caused by the flow guide Reduction in pressure loss corresponds to an additional one Chimney height or exhaust pipe length of approximately three up to ten meters, depending on the application.

Besonders günstige Strömungsverhältnisse ergeben sich dadurch, daß das Strömungsleitelement eine toroidale Umlenkfläche aufweist.Particularly favorable flow conditions result in that the flow guide element has a toroidal deflection surface having.

Das Strömungsleitelement wird vorzugsweise von dem Deckel, der den Stutzen verschließt, in letzterem gehalten. Dabei kann das Strömungsleitelement einen Bestandteil des Deckels bilden. Dies setzt allerdings voraus, daß der Deckel eine definierte Verschlußposition einnimmt, da anderfalls das Strömungsleitelement seinerseits ein Strömungshindernis bilden würde. Vorteilhafter ist es, das Strömungsleitelement als gesondertes Bauteil auszubilden. Dabei wird vorzugsweise dafür gesorgt, daß die Winkelposition des Strömungsleitelements innerhalb des Stutzens fixiert ist. Hierzu dient insbesondere eine Nase auf der Außenfläche des Strömungsleitelements, die in eine Nut auf der Innenfläche des Stutzens eingreift. Findet der Eingriff nicht statt, so läßt sich das Strömungsleitelement nicht ausreichend tief in den Stutzen einstecken. Es behindert das Aufsetzen, vorzugsweise das Aufschrauben des Deckels und signalisiert dadurch den Montagefehler. Die Nut auf der Innenfläche des Stutzens ist vorzugsweise durchgehend ausgebildet, so daß etwaiges Kondensat abgeführt werden kann.The flow guide element is preferably from the cover, which closes the nozzle, held in the latter. there the flow guide can be part of the cover form. However, this requires that the cover assumes a defined locking position, otherwise the flow guiding element in turn is an obstacle to flow would form. It is more advantageous to use the flow guiding element to be trained as a separate component. It is preferred ensured that the angular position of the flow guide is fixed within the nozzle. This serves in particular a nose on the outer surface of the flow guide element, into a groove on the inside surface of the neck intervenes. If the intervention does not take place, this can be done Flow control element not deep enough in the nozzle plug in. It hampers the touchdown, preferably that Unscrew the cover and thereby signals the assembly error. The groove on the inner surface of the nozzle is preferred continuously formed so that any condensate can be dissipated.

Eine Weiterbildung der Erfindung ist dadurch gekennzeichnet, daß das Strömungsleitelement drehbar mit dem Deckel, der den Stutzen des inneren Rohrbogens verschließt, verbunden ist. Das Strömungsleitelement kann also zusammen mit dem Deckel in den Stutzen des inneren Rohrbogens eingeschoben werden, woraufhin der Deckel mit dem Stutzen drehverriegelt wird, beispielsweise über ein Gewinde oder einen Bajonettverschluß. Die Endposition des Deckels hat dabei keinen Einfluß auf die Winkelposition des Strömungselements. Diese Winkelposition bestimmt sich vielmehr über einen formschlüssigen Eingriff des Strömungselements in den Stutzen. Der Vorteil dieser Konstruktion besteht darin, daß der Deckel und das Strömungsleitelement gemeinsam ein- und ausgebaut werden können, wobei dennoch in einfacher Weise eine korrekte Positionierung des Strömungsleitelements gewährleistet ist, und zwar sowohl bezüglich der Winkelposition als auch bezüglich der Einstecktiefe.This is a further development of the invention characterized in that the flow guide element rotatable with the Cover that closes the socket of the inner pipe bend, connected is. The flow guiding element can therefore together with the lid in the socket of the inner pipe bend are inserted, whereupon the cover with the nozzle is locked in rotation, for example via a thread or a bayonet catch. The end position of the cover has no influence on the angular position of the Flow element. This angular position is determined rather about a positive intervention of the Flow element in the nozzle. The advantage of this Construction is that the lid and that Flow guide element can be installed and removed together can, but in a simple way a correct Positioning of the flow guiding element is ensured, both in terms of angular position as well regarding the insertion depth.

Das Strömungsleitelement kann ohne weiteres als Vollkörper ausgebildet sein. Vorteilhafter, da materialsparender und im Spritzgießverfahren herstellbar, ist eine Ausbildung des Strömungsleitelementes als nach außen offener Hohlkörper. Im Inneren des Hohlkörpers befindet sich vorzugsweise ein Steg, der als Handhabe zum Herausziehen des Strömungsleitelements dient. Ist das Strömungsleitelement als Vollkörper ausgebildet, bringt man eine entsprechende Handhabe auf seiner Außenfläche an.The flow guide element can easily be a full body be trained. More advantageous because it saves material and can be produced by injection molding, is an apprenticeship of the flow guide as a hollow body open to the outside. It is preferably located inside the hollow body a web that acts as a handle for pulling out the flow guide serves. Is the flow control element as a full body trained, you bring an appropriate handle on its outer surface.

The outer pipe bend 1 contains an inner pipe bend 4, which also has a vertical arm 5 in the form of an insertion end and an im essential horizontal arm 6 in the form of a sleeve end is provided. The device is used to create a vertical, section leading to a condensing boiler Air exhaust pipe with an essentially horizontal, to connect to a chimney leading pipe section. The latter has a slight gradient in order to collect condensate Boiler attributed. The line sections are in Figure 1 not shown.

    Wie aus Figur 2 ersichtlich, ist der äußere Rohrbogen 1 in rückwärtiger Fortsetzung seiner beiden Arme 2 und 3 mit einer Öffnung 7 versehen. Diese liegt in einer Ebene, die mit den beiden Achsen der Arme 2 und 3 einen Winkel von im wesentlichen 45° bildet. Außerdem verläuft die Ebene, in der die Öffnung 7 liegt, senkrecht zu derjenigen Ebene, die von den Achsen der beiden Arme 2 und 3 aufgespannt wird.As can be seen from FIG. 2, the outer pipe bend is 1st in the rearward continuation of his two arms 2 and 3 with an opening 7 provided. This lies on a level that with the two axes of arms 2 and 3 an angle of im forms essentially 45 °. The level in which the opening 7 is perpendicular to that plane of the axes of the two arms 2 and 3 is spanned.

    Zum Verschließen der Öffnung 7 dient eine Kappe 8, die auf einen Steg 9 aufsteckbar ist, und zwar unter Zwischenschaltung eines Dichtrings 10, der von einer Nut 11 des Steges 9 aufgenommen wird. Die Dichtwirkung des Dichtrings 10 ist von sekundärer Bedeutung, da die Kappe 8 nicht die Abgasführung der Luft-Abgas-Leitung verschließt, sondern deren Luftführung. Hingegen dient der Dichtring 10 dazu, die Steckverbindung zwischen der Kappe 8 und dem Steg 9 unter Vorspannung zu sichern. Um das Aufstecken der Kappe 8 zu vereinfachen, ist deren Innenrand 12 abgeschrägt. Die Kappe 8 bildet praktische eine rückwärtige Fortsetzung des Arms 3 des äußeren Rohrbogens 1.To close the opening 7, a cap 8 is used can be plugged onto a web 9, with the interposition a sealing ring 10, the groove 11 of the web 9 is added. The sealing effect of the sealing ring 10 is of secondary importance since the cap 8 is not the exhaust system the air-exhaust pipe closes, but theirs Air duct. In contrast, the sealing ring 10 serves to Plug connection between the cap 8 and the web 9 under Secure preload. To put the cap 8 on simplify, the inner edge 12 is chamfered. The cap 8 practically forms a rearward extension of the arm 3 of the outer pipe bend 1.

    Der innere Rohrbogen 4 weist gemäß Figur 3 einen Stutzen 13 auf, der eine rückwärtige Fortsetzung des Arms 3 bildet. Der Stutzen 13 dient zur Aufnahme eines Strömungsleitelements 14, dessen Ausbildung deutlicher aus Figur 4 hervorgeht. Das Strömungsleitelement 14 ist als rückwärtig offener Hohlkörper ausgebildet und weist einen umlaufenden Flansch 15 auf, mit dem er sich an einer komplementären Schulter im Inneren des Stutzens 13 abstützt. Im unteren Bereich ist er mit einem keilförmigen Vorsprung 16 versehen, der in eine komplementäre, in Figur 3 nicht dargestellt Nut auf der Innenfläche des Stutzens 13 eingreift. Auf diese Weise ist ein Einstecken des Strömungsleitelements 14 in den Stutzen 13 des inneren Rohrbogens 4 nur in definierter Winkelposition möglich. Dies ist deshalb von ausschlaggebender Bedeutung, weil das Strömungsleitelement 14 mit einer toroidalen Umlenkfläche 17 versehen ist. Deren Gestalt ergibt sich am besten aus der perspektivischen Darstellung nach Figur 5. Die dort gezeigte abgewandelte Ausführungsform unterscheidet sich von der nach Figur 4 lediglich dadurch, daß der zylindrische Abschnitt länger ausgebildet ist und daß der keilförmige Vorsprung 16 sich nicht über die gesamte Länge des zylindrischen Abschnitts erstreckt.The inner pipe bend 4 has a nozzle according to FIG 13, which forms a rearward extension of the arm 3. The connector 13 serves to receive a flow guide element 14, the formation of which is clearer from Figure 4. The flow guide element 14 is open at the rear Hollow body formed and has a circumferential flange 15, with whom he is on a complementary shoulder in Supported inside the nozzle 13. It is in the lower area provided with a wedge-shaped projection 16 which in a complementary, not shown in Figure 3 groove on the inner surface of the connector 13 engages. That way is a Inserting the flow guide element 14 into the socket 13 of the inner pipe bend 4 only in a defined angular position possible. So this is crucial because the flow guide element 14 with a toroidal deflection surface 17 is provided. Their shape is best from the perspective view of Figure 5. Die Differed embodiment shown there differs differs from that of Figure 4 only in that the cylindrical Section is longer and that the wedge-shaped Projection 16 is not the entire length of the cylindrical portion extends.

    Das Strömungsleitelement 14 dient in montierter Lage dazu, die Abgaströmung sanft aus dem Arm 5 des inneren Rohrbogens 4 in dessen Arm 6 überzuleiten und dadurch die sonst auftretenden Druckverluste zu vermeiden.In the assembled position, the flow guide element 14 serves to the exhaust gas flow gently from the arm 5 of the inner pipe bend 4 in its arm 6 and thereby the otherwise to avoid occurring pressure losses.

    In montierter Lage wird das Strömungsleitelement 14 von einem Deckel 18 gehalten, der die Öffnung des Stutzens 13 des inneren Rohrbogens 4 verschließ. Der Deckel 18 kann in den Stutzen 13 nur dann eingeschraubt werden, wenn das Strömungsleitelement 14 ausreichend tief in den Stutzen eingesteckt ist, das heißt, mit seinem Vorsprung 16 in die komplementäre Nut eingreift und dementsprechend seine vorgegebene Winkelposition einnimmt.In the assembled position, the flow guiding element 14 from a cover 18 which holds the opening of the nozzle 13 of the inner pipe bend 4. The lid 18 can in the nozzle 13 can only be screwed in when the flow guide 14 inserted sufficiently deep into the socket is, that is, with its projection 16 in the complementary Engages groove and accordingly its predetermined Occupies the angular position.

    Zum Herausziehen des Strömungsleitelements 15 dient ein im Inneren ausgebildeter Ansatz 19, der mit zwei Fingern ergriffen werden kann.A is used to pull out the flow guide element 15 internally formed approach 19, which is gripped with two fingers can be.

    Die geneigte Öffnung 7 des äußeren Rohrbogens 1 ermöglicht einen problemlosen Einbau des inneren Rohrbogens 4. Letzterer kann durch die Öffnung 7 hindurch in den äußeren Rohrbogen 1 "eingedreht" werden. Zusätzlicher Platz durch Vergrößerung des äußeren Rohrbogens 1 ist nicht erforderlich. In montierter Lage befindet sich der Stutzen 13 des inneren Rohrbogens 4 innerhalb der Kappe 8 des äußeren Rohrbogens 1.The inclined opening 7 of the outer pipe bend 1 enables easy installation of the inner pipe bend 4. The latter can through the opening 7 in the outer Pipe elbow 1 can be "screwed in". Additional space through Enlargement of the outer pipe bend 1 is not necessary. In the assembled position, the nozzle 13 is inner pipe bend 4 within the cap 8 of the outer pipe bend 1.

    Soll die Luft-Abgas-Leitung inspiziert werden, so wird die Kappe 8 vom äußeren Rohrbogen 1 abgezogen. Sodann sind sowohl im horizontalen als auch im vertikalen Leitungsabschnitt die ringförmigen Luftführungen frei einsehbar. Auch ist der Deckel 18 des inneren Rohrbogens 4 optimal zugänglich. Er kann mühelos mit der Hand abgeschraubt werden, woraufhin sich das Strömungsleitelement 14 ohne Schwierigkeiten aus dem Stutzen 13 herausziehen läßt. Sodann ist der an den Arm 6 des inneren Rohrbogens 4 anschließende horizontale Abschnitt der Abgasführung direkt einsehbar. Lediglich der an den Arm 5 anschließende vertikale Abschnitt bedarf des Einsatzes eines Spiegels, der allerdings zur Standardausrüstung des Kaminkehrers gehört.If the air-exhaust pipe is to be inspected, then the cap 8 is removed from the outer pipe bend 1. Then are both in the horizontal and in the vertical line section the ring-shaped air ducts are freely visible. Also the cover 18 of the inner pipe bend 4 is optimally accessible. It can be easily unscrewed by hand, after which the flow guide 14 without difficulty can be pulled out of the nozzle 13. Then the one to the Arm 6 of the inner pipe bend 4 connecting horizontal section the exhaust duct can be viewed directly. Only the one the vertical section connecting the arm 5 requires use a mirror, which, however, is standard equipment heard the chimney sweep.

    Ein besonders vorteilhaftes Merkmal der Verbindungseinrichtung besteht darin, daß sämtliche Bauteile, mit Ausnahme der Dichtelemente, im Spritzgießverfahren aus Kunststoff hergestellt werden können.A particularly advantageous feature of the connection device is that all components, with the exception of the sealing elements, in the injection molding process made of plastic can be produced.

    Im Rahmen der Erfindung sind durchaus Abwandlungsmöglichkeiten gegeben. So kann die Orientierung der schrägen Öffnung des äußeren Rohrbogens anders gewählt werden, wobei allerdings die dargestellte Ausrichtung derzeit als optimal angesehen wird. Ferner können die Einsteck- und Kupplungsenden der Rohrbögen miteinander vertauscht werden, beispielsweise auch nur für einen der beiden Rohrbögen. Eine weitere Abwandlunsmöglichkeit bietet der innere Rohrbogen. Er kann als T-Stück gestaltet sein, wobei der Arm 6 direkt in den Stutzen 13 übergeht. Dabei entfällt allerdings die Möglichkeit, den Stutzen 13 mit Gefälle zum Ableiten von Kondensat zu versehen. Der Winkel zwischen den Armen der Rohrbögen kann durchaus stark von 90° abweichen.Within the scope of the invention there are possibilities for modification given. So the orientation of the oblique Opening of the outer pipe bend can be chosen differently, whereby however, the orientation shown is currently optimal is seen. Furthermore, the insertion and coupling ends the pipe bends are interchanged, for example even for one of the two pipe bends. Another The inner pipe bend offers a possibility of modification. He can be designed as a T-piece, the arm 6 directly in the Neck 13 passes. However, there is no possibility the nozzle 13 with a slope for draining condensate to provide. The angle between the arms of the pipe bends can deviate strongly from 90 °.
