Abstract

Arrangement for guiding fresh air and waste gas, in particular for a wall-mounted gas appliance, in which a waste gas pipe is arranged essentially concentrically in a fresh air pipe passing through a wall, and in which an insulating pipe is provided, which overlaps the internally situated waste gas pipe and is held on the waste gas pipe. In order, in such an arrangement, to be able easily to adapt the individual parts to the respective requirements, it is envisaged that at least two distance rings (5) are pushed onto the waste gas pipe (3), between which the insulating pipe (4) is held. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Anordnung zur Führung von Frischluft und Abgas, insbesondere für ein Gas-Wandgerät, bei der ein Abgasrohr im wesentlichen konzentrisch in einem eine Wand durchsetzenden Frischluftrohr angeordnet ist, und bei der ein das innenliegende Abgasrohr übergreifendes Isolierrohr vorgesehen ist, das auf dem Abgasrohr gehalten ist.The invention relates to an arrangement for guiding fresh air and exhaust gas, in particular for a wall-mounted gas appliance, in which an exhaust pipe is arranged essentially concentrically in a fresh air pipe passing through a wall, and in which an insulating pipe is provided which overlaps the internal exhaust pipe is held on the exhaust pipe.

Eine derartige Anordnung ist aus Dokument DE-U-8 904 865 bekannt.Such an arrangement is known from document DE-U-8 904 865.

Bei solchen bekannten Anordnungen ist es erforderlich, diese nach den jeweiligen Einbauverhältnissen nach Maß anzufertigen und einzubauen. Dabei ist ein Anpassung beim Einbau nicht möglich, wodurch sich entsprechende Probleme ergeben.In such known arrangements, it is necessary to manufacture and install them according to the respective installation conditions. An adjustment during installation is not possible, which leads to corresponding problems.

Ziel der Erfindung ist es, diese Nachteile zu vermeiden und eine Anordnung der eingangs erwähnten Art vorzuschlagen, bei der das Isolierrohr am Einbauort angepaßt werden kann.The aim of the invention is to avoid these disadvantages and to propose an arrangement of the type mentioned at the outset in which the insulating tube can be adapted at the installation site.

Erfindungsgemäß wird dies dadurch erreicht, daß auf das Abgasrohr wenigstens zwei Abstandsringe aufgeschoben sind, zwischen denen das Isolierrrohr gehalten ist.According to the invention this is achieved in that at least two spacer rings are pushed onto the exhaust pipe, between which the insulating pipe is held.

Auf diese Weise wird erreicht, daß die erfindungsgemäße Anordnung während des Einbaues an die jeweiligen Verhältnisse angepaßt werden kann.In this way it is achieved that the arrangement according to the invention can be adapted to the respective conditions during installation.

Außerdem ergibt sich bei dieser Lösung auch der Vorteil, daß die Rohre in einheitlicher Länge an die Einbaustellen gebracht und an Ort und Stelle auf die von der jeweiligen Stärke der zu durchsetzenden Mauer abhängigen Längen gebracht werden. Dabei ist das Ablängen einzelner metallischer Rohre wesentlich einfacher, als das Ablängen von werkseitig ineinandergesetzter Doppelrohre oder von mit einer Isolierschicht, die meist durch einen Schaumstoff gebildet ist, versehenen Rohren.In addition, this solution also has the advantage that the pipes are brought to the installation sites in a uniform length and are brought in place to the lengths dependent on the respective thickness of the wall to be penetrated. The cutting to length of individual metallic pipes is much easier than the cutting of double pipes fitted in the factory or pipes provided with an insulating layer, which is usually formed by a foam.

Dabei übersteigt die Länge des die Wärmeisolierung bewirkenden Rohres in der Regel die Dicke der zu durchsetzenden Rohre.The length of the pipe causing the thermal insulation generally exceeds the thickness of the pipes to be penetrated.

Nach einem weiteren Merkmal der Erfindung kann vorgesehen sein, daß die Abstandsringe Stufen aufweisen, auf denen das Isolierrohr aufsitzt.According to a further feature of the invention it can be provided that the spacer rings have steps on which the insulating tube is seated.

Durch diese Maßnahmen ergibt sich der Vorteil einer sehr einfachen Positionierung und Halterung des Isolierrohres.These measures have the advantage of very simple positioning and holding of the insulating tube.

Nach einem weiteren Merkmal der Erfindung kann vorgesehen sein, daß die Abstandsringe als Dichtung ausgebildet sind.According to a further feature of the invention it can be provided that the spacer rings are designed as a seal.

Auf diese Weise ist sichergestellt, daß ein Luftzirkulation im Ringspalt zwischen dem Abgasrohr und dem Isolierrohr unterbunden wird, wodurch sich eine besonders wirksame Wärmeisolierung des Abgasrohres erreicht wird. Dadurch wird die Bildung eines Kondensats weitgehend vermieden.This ensures that air circulation in the annular gap between the exhaust pipe and the insulating pipe is prevented, which results in particularly effective thermal insulation of the exhaust pipe is reached. This largely prevents the formation of condensate.

Weiter kann vorgesehen sein, daß die Abstandsringe aus einem wärmeisolierenden Material hergestellt sind.It can further be provided that the spacer rings are made of a heat-insulating material.

Durch diese Maßnahmen wird die Ausbildung einer Kältebrücke zwischen dem Isolierrrohr und dem Abgasrohr verhindert.These measures prevent the formation of a cold bridge between the insulating pipe and the exhaust pipe.

Die Erfindung wird nun anhand der Zeichnung näher erläutert.The invention will now be explained in more detail with reference to the drawing.

Dabei zeigen:

  • Figur 1 die erfindungsgemäße Anordnung im eingebauten Zustand,
  • Figur 2 eine für den Einbau vorgesehene Einheit,
  • Figur 3 eine weitere erfindungsgemäße Anordnung und
  • Figur 4 ein Schnitt gemäß der Linie IV-IV in der Figur 3.
Show:
  • 1 shows the arrangement according to the invention in the installed state,
  • FIG. 2 shows a unit intended for installation,
  • Figure 3 shows another arrangement according to the invention and
  • FIG. 4 shows a section along the line IV-IV in FIG. 3.

Die Anordnung nach der Figur 1 weist ein metallenes Frischluftrohr 1 auf, das eine Mauer 2 durchsetzt. Innerhalb dieses Frischluftrohres 1 ist ein gleichfalls metallenes Abgasrohr 3 konzentrisch gehalten. Über den Ringraum zwischen diesen beiden ineinander angeordneten Rohren ist ein nicht dargestelltes Gasgerät mit Frischluft versorgt. Die Abfuhr des Abgases ist über das Innenrohr sichergestellt.The arrangement according to FIG. 1 has a metal fresh air pipe 1 which passes through a wall 2. Within this fresh air pipe 1, a likewise metallic exhaust pipe 3 is held concentrically. A gas device (not shown) is supplied with fresh air via the annular space between these two nested tubes. The exhaust gas is discharged through the inner tube.

Das Abgasrohr 3 ist mit einem zur Wärmeisolierung dienenden Isolierrohr 4 versehen. Dieses Isolierrohr 4 ist über zwei Abstandsringe 5 auf dem Abgasrohr 3 abgestützt, wobei diese Abstandsringe 5 vorzugsweise aus einem schlecht wärmeleitendem Material, wie zum Beispiel Kunststoff, hergestellt sind.The exhaust pipe 3 is provided with an insulating pipe 4 for thermal insulation. This insulating tube 4 is supported on the exhaust pipe 3 via two spacer rings 5, these spacer rings 5 preferably being made of a poorly heat-conducting material, such as plastic.

Durch das Isolierrohr 4 ist sichergestellt, daß sich im mündungsnahen Bereich des Abgasrohres 3 ein Luftmantel vorhanden ist, der eine entsprechende Wärmeisolierung für das Abgasrohr sichert. Dadurch wird verhindert, daß sich bei einer Wiederaufnahme des Betriebes des nicht dargestellten Heizgerätes nach einer längeren Betriebspause Kondensat an der Wand des Abgasrohres 3, das im mündungsnahen Bereich relativ niedrige Temperaturen während der Betriebspause annehmen kann, niederschlagen kann.The insulating tube 4 ensures that an air jacket is present in the region of the exhaust pipe 3 near the mouth, which ensures appropriate thermal insulation for the exhaust pipe. This prevents condensate from settling on the wall of the exhaust pipe 3 when the heater (not shown) resumes operation after a lengthy break in operation, which can assume relatively low temperatures during the break in the area near the mouth.

Die Anordnung, die aus einem Zuluftrohr 1, einem Abgasrohr 3 und einem auf diesem über die Abstandsringe 5 abgestützten Isolierrohr 4 besteht, wird zweckmäßigerweise am Ort der Anwendung fertiggestellt (Figur 2). Dabei weisen diese Rohre zweckmäßigerweise eine für dicke Mauern ausreichende Länge auf. Die Rohre 1, 3 und 4 können dann leicht auf die für die jeweilige Dicke der Mauer 2 erforderlichen Maße x, x′, x˝ abgelängt werden.The arrangement, which consists of an inlet air pipe 1, an exhaust pipe 3 and an insulating pipe 4 supported thereon via the spacer rings 5, is expediently completed at the place of use (FIG. 2). These pipes expediently have a length sufficient for thick walls. The tubes 1, 3 and 4 can then easily be cut to the required dimensions x, x ', x˝ for the respective thickness of the wall 2.

Bei der Ausführungsform nach den Figuren 3 und 4 ist das Isolierrohr 4 im Bereich eines Rohrbogens des Abgasrohres 3 angeordnet. Dabei besteht das Isolierrohr 4 aus zwei Halbschalen 14, 14′, wobei die Halbschale 14 entlang ihrer Längsränder mit offenen Falzen 15 versehen sind, in die die nach außen abgewinkelten Ränder 16 der Halbschale 14′ einschiebbar sind.In the embodiment according to FIGS. 3 and 4, the insulating pipe 4 is arranged in the region of a pipe bend of the exhaust pipe 3. The insulating tube 4 consists of two half-shells 14, 14 ', the half-shell 14 being provided along its longitudinal edges with open folds 15 into which the outwardly angled edges 16 of the half-shell 14' can be inserted.
