Description

Stand der TechnikState of the art

Die Erfindung betrifft einen Zuluft- und Abluftadapter für ein Heizgerät, das mindestens eine Eingangsöffnung für die Zuluft und mindestens eine Ausgangsöffnung für die Abluft aufweist, wobei der Zuluft- und Abluftadapter ein Gehäuse mit Aufnahmen für die Eingangsöffnung und die Ausgangsöffnung aufweist.The invention relates to a supply air and exhaust air adapter for a heater which has at least one input opening for the supply air and at least one output opening for the exhaust air, the supply air and exhaust air adapter having a housing with receptacles for the input opening and the output opening.

Zuluft- und Abluftadapter für Heizgeräte werden benötigt, wenn zum Beispiel ein neues Heizgerät montiert oder ein bisheriges Heizgerät ersetzen soll und feste Anschlussbedingungen für die Zuluft und die Abluft vorliegen. Es besteht dabei die Schwierigkeit, die Adapter so auszuführen, dass ein Austreten der Abluft, also des Rauchgases, sicher und auf lange Zeit verhindert wird.Supply air and extract air adapters for heaters are required if, for example, a new heater is to be installed or a previous heater is to be replaced and there are fixed connection conditions for the supply air and extract air. There is a difficulty in designing the adapters in such a way that the exhaust air, i.e. the flue gas, is prevented from escaping safely and for a long time.

Beispiele von Zulüft- und Abluftadaptern sind aus den Dokumenten NL 1017675 oder NL 9100209 bekannt. Dokument NL 1017675 offenbart einen Zuluft- und Abluftadapter nach dem Oberbegriff des Anspruchs 1.Examples of supply and exhaust air adapters are from the documents NL 1017675 or NL 9100209 known. document NL 1017675 discloses a supply air and exhaust air adapter according to the preamble of claim 1.

Offenbarung der ErfindungDisclosure of the invention Vorteileadvantages

Der erfindungsgemäße Zuluft- und Abluftadapter, bei dem ein Durchgangsweg und ein Abzweigweg innerhalb des Gehäuses vorgesehen sind, hat den Vorteil, dass Abluft, wenn sie austreten sollte, wieder in das System zurück abgeleitet wird. Ein unkontrolliertes Austreten beispielsweise in den Aufstellraum ist damit vermieden.The supply air and exhaust air adapter according to the invention, in which a passage and a branch path are provided within the housing, has the advantage that exhaust air, if it should escape, is discharged back into the system. An uncontrolled escape, for example, into the installation room is avoided.

Erfindungsgemäß weist der Durchgangsweg einen Einlass sowie einen Auslass auf und mindestens eine Dichtungsaufnahme für eine Dichtung am Auslass ist vorgesehen.According to the invention, the passageway has an inlet and an outlet, and at least one seal receptacle for a seal at the outlet is provided.

Die Sicherheit erhöht sich, wenn der Durchgangsweg innerhalb eines weiteren Durchgangswegs angeordnet ist. Erfindungsgemäß weist der Durchgangsweg und/oder der weitere Durchgangsweg Dichtungsaufnahmen für Dichtungen auf.Security increases if the passage is arranged within a further passage. According to the invention, the through path and / or the further through path has seal receptacles for seals.

Ist der Durchgangsweg kürzer als der weitere Durchgangsweg, bleibt der Anschluss innerhalb des Gehäuses und erhöht damit weiter die Sicherheit.If the passageway is shorter than the further passageway, the connection remains within the housing and thus further increases security.

Eine einfache Ausgestaltung ergibt sich, wenn der Abzweigweg einen Einlass sowie einen Auslass aufweist und der Auslass mit dem weiteren Durchgangsweg verbunden oder identisch ist.A simple configuration results if the branch path has an inlet and an outlet and the outlet is connected to the further through path or is identical.

Gehört zum Zuluft- und Abluftadapter mindestens ein erster Einsatz, der den Auslass des weiteren Durchgangswegs zu verschließen vermag, erhöht sich die Variabilität. Diese wird weiter erhöht, wenn mindestens ein zweiter Einsatz vorgesehen ist, der den Auslass des Abzweigwegs zu verschließen vermag. Eine nochmalige Erhöhung der Variabilität ergibt sich, wenn mindestens ein Reduziereinsatz vorgesehen ist, der den Durchgangsweg und/oder den weiteren Durchgangsweg im Durchmesser zu reduzieren vermag.If the supply air and extract air adapter includes at least one first insert that can close the outlet of the further passage, the variability increases. This is further increased if at least one second insert is provided which is able to close the outlet of the branch path. The variability is increased again if at least one reducing insert is provided which is capable of reducing the diameter of the passage and / or the further passage.

In einer bevorzugten Ausführungsform weist der Durchgangsweg einen Durchmesser von 80 mm, der weitere Durchgangsweg einen Durchmesser von 125 mm und der Abzweigweg eine Durchmesser von 80 mm auf. Damit sind die gängigen Zuluft- und Abluftwege einfach anschließbar.In a preferred embodiment, the through path has a diameter of 80 mm, the further through path has a diameter of 125 mm and the branch path has a diameter of 80 mm. This makes it easy to connect the common supply and exhaust air routes.

Beschreibungdescription

In den Figuren 1 und 2 ist ein Zuluft- und Abluftadapter 10 dargestellt. Der Zuluft-und Abluftadapter 10 besitzt ein Gehäuse 12 mit einer Aufnahme 14 für eine Eingangsöffnung für die Zuluft für ein Heizgerät sowie eine Aufnahme 16 für eine Ausgangsöffnung für die Abluft des Heizgeräts.In the Figures 1 and 2nd A supply air and exhaust air adapter 10 is shown. The supply air and exhaust air adapter 10 has a housing 12 with a receptacle 14 for an inlet opening for the inlet air for a heater and a receptacle 16 for an outlet opening for the outlet air of the heater.

Ferner sind in Figur 1 mögliche Einsätze für den erfindungsgemäßen Zuluft- und Abluftadapter 10 dargestellt. So sind ein erster Einsatz 20, ein zweiter Einsatz 22 sowie ein Reduziereinsatz 24 gezeichnet, die jedoch später erst beschrieben werden.Furthermore, in Figure 1 possible uses for the supply air and extract air adapter 10 according to the invention are shown. A first insert 20, a second insert 22 and a reducing insert 24 are drawn, but these will only be described later.

In dem Gehäuse 12 ist, wie das in Figur 2 zu erkennen ist, ein Durchgangsweg 26 sowie ein Abzweigweg 28 vorgesehen. Der Durchgangsweg 26 weist einen Einlass 30 und einen Auslass 32 auf, wobei sich am Einlass 30 die Aufnahme 16 für die Ausgangsöffnung für die Abluft des Heizgerät befindet. Am Auslass 32 befindet sich eine weitere Aufnahme 34, an die ein weiterführendes Rohr anschließbar ist.In the housing 12 is like that in Figure 2 A through path 26 and a branch path 28 can be seen. The passage 26 has an inlet 30 and an outlet 32, the receptacle 16 for the outlet opening for the exhaust air of the heater being located at the inlet 30. At the outlet 32 there is another receptacle 34 to which a further pipe can be connected.

Am Auslass 32, im Bereich der Aufnahme 34, ist eine Dichtung 36 vorgesehen, über die das dann aufgenommene, weiterführende Rohr abgedichtet werden kann. Am Einlass 30 bzw. dessen Aufnahme 16 ist ebenfalls eine Aufnahme 38 mit einer Dichtung (nicht eingezeichnet) vorgesehen. Der Zuluft- und Abluftadapter 10 wird über den Einlass 30 mit einem Rauchgasauslass eines Heizungsgeräts verbunden. Das Rauchgas strömt also durch den Durchgangsweg 26 vom Heizgerät in ein weiterführendes Rohr und dann in die Atmosphäre. Das weiterführende Rohr ist als Strichpunktlinie angedeutet.At the outlet 32, in the area of the receptacle 34, a seal 36 is provided, via which the pipe which is then received and can be sealed can be sealed. A receptacle 38 with a seal (not shown) is likewise provided at the inlet 30 or its receptacle 16. The supply air and extract air adapter 10 is connected via the inlet 30 to a flue gas outlet of a heating device. The flue gas thus flows through the passage 26 from the heater into a further pipe and then into the atmosphere. The further pipe is indicated as a dash-dot line.

Der Durchgangsweg 26 ist im Gehäuse 12 innerhalb eines weiteren Durchgangsweg 40 angeordnet. Die Anordnung ist so getroffen, dass der Durchgangsweg 26 innerhalb des weiteren Durchgangswegs 40 konzentrisch angeordnet ist. Zur Befestigung sind Stege 42 vorgesehen, die sich von der Innenseite des weiteren Durchgangswegs 40 zur äußeren Seite des Durchgangswegs 26 erstrecken und diese verbinden.The passage 26 is arranged in the housing 12 within a further passage 40. The arrangement is such that the Passage 26 is arranged concentrically within the further passageway 40. For fastening webs 42 are provided, which extend from the inside of the further passage 40 to the outside of the passage 26 and connect them.

Der weitere Durchgangsweg 40 kann für die Zuluft, also die von außen dem Heizgerät zugeführte Frischluft verwendet werden. Dazu sind an den Eingangs- und Ausgangsseiten des weiteren Durchgangswegs 40 Aufnahmen 44 für das Heizgerät einerseits und ein weiterführendes Rohr andererseits vorgesehen. Die Aufnahmen sind mit Ausnehmungen 46 für Dichtungen 48 ausgestattet, die teilweise dargestellt sind.The further passage 40 can be used for the supply air, ie the fresh air supplied to the heater from the outside. For this purpose, receivers 44 for the heater on the one hand and a further pipe on the other are provided on the input and output sides of the further passage 40. The receptacles are equipped with recesses 46 for seals 48, which are partially shown.

Wird über den weiteren Durchgangswegs 40 Frischluft geführt, so wird die Zuluft über dessen Einlass 41 zu dessen Auslass 43 geführt. Da die Frischluft der Abluft entgegenströmt, befindet sich der Einlass 41 des weiteren Durchgangswegs 40 im Bereich des Auslasses 32 des Durchgangswegs 32. Auf der Seite des Einlasses 30 schließt der Durchgangswegs 26 bündig mit dem weiteren Durchgangsweg 40 und dessen Auslass 43 ab.If fresh air is routed via the further passage 40, the supply air is routed via its inlet 41 to its outlet 43. Since the fresh air flows against the exhaust air, the inlet 41 of the further passage 40 is located in the region of the outlet 32 of the passage 32. On the side of the inlet 30, the passage 26 is flush with the further passage 40 and its outlet 43.

Im Bereich des Auslasses 32 ist der Durchgangsweg 26 kürzer als der weitere Durchgangsweg 40 und bleibt deshalb ein Stück innerhalb des Gehäuses 12 zurück. Diese Verkürzung beträgt zwischen 0,3 cm und 3 cm. Auf den Zweck dieser Verkürzung wird später eingegangen.In the area of the outlet 32, the through path 26 is shorter than the further through path 40 and therefore remains a bit within the housing 12. This shortening is between 0.3 cm and 3 cm. The purpose of this shortening will be discussed later.

Der Abzweigweg 28 weist einen Einlass 50 sowie einen Auslass 52 auf. Am Auslass 52 ist die Aufnahme 14 für die Eingangsöffnung für die Zuluft des Heizgeräts angeformt. Das heißt, im Ausführungsbeispiel ist der Auslass 52 mit einem Auslass 43 des weiteren Durchgangswegs 40 identisch. Der Abzweigweg 28 zweigt vom weiteren Durchgangswegs 40 ab bzw. mündet in diesen, wenn man das in Strömungsrichtung der Zuluft betrachtet. Im Bereich des Einlasses 50 weist der Abzweigweg 28 eine Aufnahme 54 auf, die eine Dichtung 56 aufnehmen kann und in die ein weiterführendes Rohr einsteckbar ist.The branch path 28 has an inlet 50 and an outlet 52. The receptacle 14 for the inlet opening for the supply air of the heater is molded onto the outlet 52. That is, in the exemplary embodiment, the outlet 52 is identical to an outlet 43 of the further passage 40. The branching path 28 branches off from the further through path 40 or opens into this, if one considers this in the direction of flow of the supply air. In the area of the inlet 50, the branching path 28 has a receptacle 54 which can receive a seal 56 and into which a further pipe can be inserted.

Die Zuluft kann also entweder durch den Abzweigweg 28 oder durch den weiteren Durchgangswegs 40 von außen einem Heizgerät zugeführt werden.The supply air can thus be supplied to a heater from outside either through branch path 28 or through further passage 40.

Das Gehäuse 12 weist eine verschließbare Öffnung 57 auf, die über ein nicht dargestelltes Röhrchen mit dem Durchgangsweg 26 verbunden ist. Hierrüber können bei Wartungsarbeiten Messungen der Abluft vorgenommen werden.The housing 12 has a closable opening 57, which is connected to the through-way 26 via a tube (not shown). This allows measurements of the exhaust air to be carried out during maintenance work.

In den Figuren 3 bis 5 sind drei verschiedene Einsatzvarianten für den Zuluft- und Abluftadapter 10 gezeigt. Allen Ausführungsbeispielen ist gemein, dass sie für ein Heizgerät verwendet werden, bei dem das Rauchgas, also die Abluft konzentrisch innerhalb der Zuluft, auch Frischluft oder Verbrennungsluft genannt, geführt ist. Das heißt, dass die Eingangsöffnung des Heizgeräts konzentrisch zu dessen Ausgangsöffnung angeordnet ist. Auch beim erfindungsgemäßen Zuluft-und Abluftadapter 10 sind deshalb der Einlass 30 für den Durchgangswegs 26 und der Auslass 43 für den weiteren Durchgangsweg konzentrisch angeordnet und mit entsprechenden Aufnahmen 14,16 ausgestattet.In the Figures 3 to 5 three different application variants for the supply air and extract air adapter 10 are shown. All of the exemplary embodiments have in common that they are used for a heater in which the flue gas, that is to say the exhaust air, is guided concentrically within the supply air, also called fresh air or combustion air. This means that the inlet opening of the heater is arranged concentrically with its outlet opening. In the supply air and exhaust air adapter 10 according to the invention, therefore, the inlet 30 for the passage 26 and the outlet 43 for the further passage are arranged concentrically and equipped with corresponding receptacles 14, 16.

In Figur 3 ist eine Einsatzvariante gezeigt, bei der der Zuluft- und Abluftadapter 10 die Zuluft bzw. die Abluft von der konzentrischen Luftführung am Heizgeräteausgang auf eine parallele Luftführung wechselt. Dazu ist ein Einsatz 20 vorgesehen, der den Einlass 41 des weiteren Durchgangswegs 40 abzudecken vermag. Hierfür weist der erste Einsatz 20 einen kreisringförmigen Deckel 58 auf, dessen äußerer Durchmesser 60 größer ist als der Durchmesser 62 der lichten Weite des weiteren Durchgangswegs 40. Am Deckel 58 ist ein Rohrstück 64 angebracht, dessen Außendurchmesser dem Durchmesser 62 des weiteren Durchgangswegs 40 entspricht. Der erste Einsatz 20 kann folglich mit dem Rohrstück 64 in den weiteren Durchgangswegs 40 eingeschoben werden. Über die Dichtungen 48 wird der erste Einsatz 20 nach außen abgedichtet.In Figure 3 An application variant is shown in which the supply air and exhaust air adapter 10 changes the supply air or the exhaust air from the concentric air duct at the heater outlet to a parallel air duct. For this purpose, an insert 20 is provided which is capable of covering the inlet 41 of the further passage 40. For this purpose, the first insert 20 has an annular cover 58, the outer diameter 60 of which is larger than the diameter 62 of the clear width of the further passage 40. A piece of pipe 64 is attached to the cover 58, the outer diameter of which corresponds to the diameter 62 of the further passage 40. The first insert 20 can thus be inserted with the pipe section 64 into the further passage 40. The first insert 20 is sealed to the outside via the seals 48.

Der kreisringförmige Deckel 58 weist eine innere Öffnung 66 auf, deren lichte Weite dem Innendurchmesser 68 des Durchgangswegs 26 entspricht. Wenn also der erste Einsatz 20 auf das Gehäuse 12 aufgesteckt ist, ist der weitere Durchgangsweg 40 versperrt, es kann jedoch ein weiterführendes Rohr durch die innere Öffnung 66 in den Durchgangsweg 26 eingesteckt werden.The annular cover 58 has an inner opening 66, the clear width of which corresponds to the inner diameter 68 of the passage 26. Thus, if the first insert 20 is plugged onto the housing 12, the further passage 40 is blocked, but a further pipe can be inserted into the passage 26 through the inner opening 66.

Die Zuluft wird dann über den Einlass 50 des Abzweigwegs 28 geführt. Der innere Durchmesser 70 des Einlasses 50 entspricht einem Standardmaß und beträgt im Ausführungsbeispiel 80 mm. Ebenso entsprechen der Durchmesser 62 des weiteren Durchgangswegs 40 sowie der Durchmesser 68 des Durchgangswegs 26 Standardmaßen. Im Ausführungsbeispiel hat der Durchmesser 62 eine Größe von 125 mm, der Innendurchmesser hat eine Größe von 80 mm.The supply air is then passed through the inlet 50 of the branch path 28. The inner diameter 70 of the inlet 50 corresponds to a standard dimension and is 80 mm in the exemplary embodiment. Likewise, the diameter 62 of the further passage 40 and the diameter 68 of the passage 26 correspond to standard dimensions. In the exemplary embodiment, the diameter 62 has a size of 125 mm, the inner diameter has a size of 80 mm.

Eine dem Ausführungsbeispiel nach Figur 3 entsprechende Luftführung ist in Figur 6 dargestellt. In vergrößerter Darstellung ist der erste Einsatz 20 erkennbar, der im weiteren Durchgangsweg 40 sitzt, über die Dichtung 48 abgedichtet ist und mit dem Deckel 58 den weiteren Durchgangsweg 40 verschließt. Ferner ist erkennbar, dass ein weiterführendes Rohr 72 im Durchgangsweg 26 sitzt und über die Dichtung 36 abgedichtet ist. Die Abluft folgt im normalen Fall dem Pfeil 74, während die Zuluft den Pfeilen 76 folgt. Sollte die Dichtung 36 undicht werden und die Abluft entlang des Pfeils 78 entweichen, wird diese von der Zuluft entlang der Pfeile 76 mitgenommen (Venturi-Effekt) und wieder ins Heizgerät geführt. Damit ist sichergestellt, dass keine Abluft aus diesem Bereich in den Aufstellraum des Heizgeräts entweichen kann. Dieser Effekt wird dadurch erreicht, dass - wie bereits beschrieben - der Durchgangsweg 26 gegenüber dem weiteren Durchgangsweg 40 ein Stück zurückbleibt. Im Ausführungsbeispiel ist dieser Abstand 81 in der Größenordnung von 2 cm. Zur weiteren Erhöhung der Sicherheit weist die innere Öffnung 66 im Ausführungsbeispiel eine zusätzliche Dichtung 80 auf.One according to the embodiment Figure 3 corresponding air flow is in Figure 6 shown. In an enlarged view, the first insert 20 can be seen, which sits in the further passage 40, is sealed by the seal 48 and closes the further passage 40 with the cover 58. It can also be seen that a further pipe 72 is seated in the passage 26 and is sealed by the seal 36. The exhaust air follows the arrow 74 in the normal case, while the supply air follows the arrows 76. If the seal 36 leaks and the exhaust air escapes along the arrow 78, it is taken along by the supply air along the arrows 76 (Venturi effect) and fed back into the heater. This ensures that no exhaust air can escape from this area into the heater's installation room. This effect is achieved in that - as already described - the passage 26 remains a bit behind the other passage 40. In the exemplary embodiment, this distance 81 is of the order of 2 cm. To further increase security, the inner opening 66 has an additional seal 80 in the exemplary embodiment.

Dieser Effekt kann auch bei kleineren Abständen erreicht werden. Es ist auch möglich, den Deckel 58 mit einer Ausstülpung zu versehen, dann kann der Durchgangsweg 26 bis zur Höhe des äußeren Randes des Gehäuses 12 reichen. Wesentlich ist, dass die Dichtung 36 in Strömungsrichtung der Zuluft hinter der Dichtung 80 liegt. Im Bereich der Dichtung 36 ausströmende Abluft wird dann von der Dichtung 80 vor dem Austritt in den Aufstellraum gehindert und von der Zuluft mit in den Verbrennungsraum geführt.This effect can also be achieved with smaller distances. It is also possible to provide the cover 58 with a protuberance, in which case the passage 26 can extend to the height of the outer edge of the housing 12. It is essential that the seal 36 lies behind the seal 80 in the flow direction of the supply air. Exhaust air flowing out in the area of the seal 36 is then prevented by the seal 80 from exiting into the installation space and carried by the supply air into the combustion space.

Im Ausführungsbeispiel nach Figur 4 ist der Einlass 50 des Abzweigwegs 28 mit dem zweiten Einsatz 22 verschlossen. Dazu weist der Einsatz 22 einen kreisförmigen Deckel 82 auf, dessen äußerer Durchmesser größer ist, als der innere Durchmesser 70 des Einlasses 50. An den Deckel 82 schließt sich ein Rohrstück 84 an, dessen Durchmesser dem Durchmesser 70 entspricht. Ist der zweite Einsatz 22 eingesteckt, dichtet die Dichtung 56 den Einlass 50 am Rohrstück 84 ab.In the embodiment according to Figure 4 the inlet 50 of the branch path 28 is closed with the second insert 22. For this purpose, the insert 22 has a circular cover 82, the outer diameter of which is larger than the inner diameter 70 of the inlet 50. A pipe section 84 adjoins the cover 82, the diameter of which corresponds to the diameter 70. If the second insert 22 is inserted, the seal 56 seals the inlet 50 on the pipe section 84.

Die Zuluft wird folglich über den weiteren Durchgangsweg 40 zugeführt. Im Ausführungsbeispiel nach Figur 4 wird dazu ein Reduziereinsatz 24 in den weiteren Durchgangsweg 26 eingebracht. Der Reduziereinsatz 24 weist einen kreisringförmigen Deckel 86 auf, dessen äußerer Durchmesser größer ist als der Durchmesser 62 des weiteren Durchgangswegs 40. An den Deckel 86 schließt sich ein Rohrstück 88 an, dessen Durchmesser dem Durchmesser 62 des weiteren Durchgangswegs 40 entspricht und der über die Dichtung 48 abgedichtet wird. Da der Abzweigweg 28 über den zweiten Einsatz 22 verschlossen ist, kann das Rohrstück 88 des Reduziereinsatzes 24 länger sein als das Rohrstück 64 des ersten Einsatzes 20. Der kreisringförmige Deckel 86 weist eine innere Öffnung 90 auf, die einen gegenüber dem Durchmesser 62 reduzierten inneren Durchmesser 92 besitzt. Im Bereich der inneren Öffnung 90 ist eine Dichtung 94 angebracht, die ein eingestecktes, weiterführendes Rohr abzudichten vermag.The supply air is consequently supplied via the further passage 40. In the embodiment according to Figure 4 For this purpose, a reducing insert 24 is introduced into the further passage 26. The reducing insert 24 has an annular cover 86, the outer diameter of which is larger than the diameter 62 of the further passage 40. A piece of pipe 88 is connected to the cover 86, the diameter of which corresponds to the diameter 62 of the further passage 40 and that via the seal 48 is sealed. Since the branch path 28 is closed by the second insert 22, the tube piece 88 of the reducing insert 24 can be longer than the tube piece 64 of the first insert 20. The annular cover 86 has an inner opening 90 which has an inner diameter that is reduced compared to the diameter 62 92 owns. In the area of the inner opening 90, a seal 94 is attached, which is able to seal an inserted, further pipe.

Im Reduziereinsatz 24 ist ein Reduzierrohr 96 angeordnet, dessen äußerer Durchmesser dem Innendurchmesser 68 des Durchgangswegs 26 entspricht. An seinem oberen Ende ist der Innendurchmesser 98 gegenüber dem Innendurchmesser 68 reduziert. Wird das Reduzierrohr 96 in den Durchgangswegs 26 eingesetzt, dichtet die Dichtung 36 den Durchgangsweg ab. Um auch ein weiterführendes Rohr, das in das Reduzierrohr 96 eingesetzt wird, abzudichten, weist die Auslassöffnung 100 eine Dichtung 102 auf.A reducing tube 96 is arranged in the reducing insert 24, the outer diameter of which corresponds to the inner diameter 68 of the passage 26. At its upper end, the inner diameter 98 is reduced compared to the inner diameter 68. If the reducing tube 96 is inserted into the passage 26, the seal 36 seals the passage. In order to also seal a further pipe that is inserted into the reducing pipe 96, the outlet opening 100 has a seal 102.

Das Reduzierrohr 96 kann als loses, separates Bauteil ausgeführt sein, das im Verwendungsfall separat in den Durchgangsweg 26 eingesteckt wird. Im Ausführungsbeispiel ist es aber über Stege 104 am Rohrstück 88 befestigt. Das hat den Vorteil, dass nach der Montage des Zuluft- und Abluftadapters 10 und Anschluss der entsprechenden weiterführenden Rohre sichergestellt ist, dass das Reduzierrohr 96 auch tatsächlich montiert ist.The reducing pipe 96 can be designed as a loose, separate component which, when in use, is inserted separately into the passage 26. In the exemplary embodiment, however, it is fastened to the tube piece 88 via webs 104. The has the advantage that after installation of the supply air and exhaust air adapter 10 and connection of the corresponding further pipes, it is ensured that the reducing pipe 96 is actually installed.

Im Ausführungsbeispiel nach Figur 4 wird der konzentrisch geführte Anschluss des Heizgerätes auf einen konzentrisch geführten Zuluft- und Abluftkanal auf vorbestimmte, in der Hausinstallation vorkommende Größen reduziert. So weist im Ausführungsbeispiel der Durchmesser 92 eine Größe von 100 mm auf, während der Durchmesser 98 eine Größe von 60 mm hat.In the embodiment according to Figure 4 the concentrically routed connection of the heater to a concentrically routed supply air and exhaust air duct is reduced to predetermined sizes that occur in the house installation. Thus, in the exemplary embodiment, the diameter 92 has a size of 100 mm, while the diameter 98 has a size of 60 mm.

Im Ausführungsbeispiel nach Figur 5 ist der Einlass 50 des Abzweigwegs 28 wieder mit dem zweiten Einsatz 22 abgeschlossen. Sowohl der Durchgangsweg 26 als auch der weitere Durchgangsweg 40 sind nach außen offen, so dass weiterführende Rohre mit einem Außendurchmesser entsprechend dem Innendurchmesser 68 bzw. entsprechend dem Durchmesser 62 des weiteren Durchgangswegs 40 eingesetzt werden können. Im Ausführungsbeispiel beträgt der Durchmesser 62 des weiteren Durchgangswegs 125 mm und der Durchmesser 68 des Durchgangswegs 26 beträgt 80 mm.In the embodiment according to Figure 5 the inlet 50 of the branch path 28 is closed again with the second insert 22. Both the passage 26 and the further passage 40 are open to the outside, so that further pipes with an outer diameter corresponding to the inner diameter 68 or corresponding to the diameter 62 of the further passage 40 can be used. In the exemplary embodiment, the diameter 62 of the further passage is 125 mm and the diameter 68 of the passage 26 is 80 mm.

Mit den genannten Größen der jeweiligen Durchmesser lassen sich die meisten Standardgrößen, die in Wohnungen und Häusern vorkommen, abbilden. Sollten dennoch andere Verhältnisse vorherrschen, kann darauf mit entsprechenden Einsätzen reagiert werden. So ist es beispielsweise möglich, auch beim zweiten Einsatz eine innere Öffnung vorzusehen. Ferner ist es auch denkbar, statt einer Reduzierung eine Vergrößerung vorzusehen, beispielsweise indem an die jeweiligen Deckel entsprechend größere Rohrstücke nach außen angebracht sind.Most of the standard sizes that occur in apartments and houses can be represented with the sizes of the respective diameters mentioned. Should other conditions prevail, you can respond with appropriate operations. For example, it is also possible to provide an inner opening when used a second time. Furthermore, it is also conceivable to provide an enlargement instead of a reduction, for example by fitting correspondingly larger pipe sections to the outside.
