Abstract

1. A chimney having a lateral orifice in the chimney wall, in which a trapping device (5) for condensation water is provided on the inside of the chimney wall (2), characterised in that a draining device (6), projecting above the orifice on both sides, is provided above the lateral orifice (3).

Description

Die Erfindung betrifft einen Schornstein mit seitlicher Öffnung in der Schornsteinwandung, wobei eine Auffangvorrichtung für Kondenswasser an der Innenseite der Schornsteinwandung vorgesehen ist.The invention relates to a chimney with a lateral opening in the chimney wall, a collecting device for condensed water being provided on the inside of the chimney wall.

Bei neueren Wärmeerzeugern liegt die Abgastemperatur bei Eintritt in den Schornstein niedriger als bisher üblich, zum Teil unter der Wasserdampftaupunkttemperatur bzw. dem Säuretaupunkt der Abgase. Dies bringt es mit sich, daß an der Innenwandung des Schornsteins Kondensfeuchtigkeit niederschlägt, die an der Schornsteininnenwandung nach unten hinunterläuft. Es ist daher bekannt, an der untersten Stelle des Schornsteins Wassersammelschalen zum Auffangen des Kondensats anzuordnen.In newer heat generators, the flue gas temperature when entering the chimney is lower than previously, sometimes below the water vapor dew point temperature or the acid dew point of the flue gases. This means that condensation forms on the inner wall of the chimney and runs down the inner wall of the chimney. It is therefore known to arrange water collecting trays at the lowest point of the chimney for collecting the condensate.

Aus der DE-B-1159121 ist ein Schornstein bekannt, bei dem nahe dem unteren Ende eine Auffangvorrichtung für Kondenswasser an der Innenseite der Schornsteinwandung vorgesehen ist. Diese Auffangvorrichtung ist mit einer Rohrleitung verbunden, die das gesammelte Kondensat nach außen führt.A chimney is known from DE-B-1159121, in which a condensate collecting device is provided near the lower end on the inside of the chimney wall. This collecting device is connected to a pipeline that leads the collected condensate to the outside.

Eine derartige Auffangvorrichtung für Kondensat an jeder seitlichen Öffnung in der Schornsteinwandung, beispielsweise zum Anschluß an den Wärmeerzeuger oder zur Bildung einer Reinigungsöffnung, vorzusehen, ist sehr umständlich und aufwendig.Such a device for collecting condensate at each side opening in the chimney wall, for example to connect to the heat generator or to form a cleaning opening, is very cumbersome and complex.

Die Aufgabe der Erfindung besteht daher darin, einen Schornstein der eingangs genannten Art derart weiterzubilden, daß das an der Innenseite der Schornsteinwandung herunterfließende Kondensat vor der seitlichen Öffnung in einfacher Weise aufgefangen und abgeleitet wird.The object of the invention is therefore to develop a chimney of the type mentioned in such a way that the condensate flowing down on the inside of the chimney wall is collected and discharged in a simple manner in front of the lateral opening.

Diese Aufgabe wird dadurch gelöst, daß oberhalb der seitlichen Öffnung eine die Öffnung beidseitig überragende Abflußvorrichtung vorgesehen ist.This object is achieved in that a drain device projecting beyond the opening on both sides is provided above the lateral opening.

Vorteilhaft sind die Auffang- und Abflußvorrichtung ·als in die Schornsteininnenwandung eingelassene Rille ausgebildet, wobei die Rille auch in der Innenwandung der seitlichen Öffnung verlaufen kann. Nach einer anderen Ausführungsform sind die Auffang- und Abflußvorrichtung als auf der Schornsteininnenwandung angeordnete Abflußrinne ausgebildet.The collecting and drainage device is advantageously designed as a groove embedded in the chimney inner wall, the groove also being able to run in the inner wall of the lateral opening. According to another embodiment, the collecting and drainage device are designed as a drainage channel arranged on the inside of the chimney.

Die Auffang- und Abflußvorrichtung sind schräg nach unten geneigt. Bei einer vorteilhaften Ausführungsform sind sie dachartig zu beiden Seiten der Öffnungen geneigt ausgebildet. Nach einer anderen Ausführungsform sind sie bogenförmig geneigt ausgebildet.The collecting and drainage devices are inclined downwards. In an advantageous embodiment, they are roof-like inclined to both sides of the openings. According to another embodiment, they are curved in an arcuate manner.

Die Abflußvorrichtung ist bei Schornsteinen mit rechteckigem Querschnitt vorteilhaft bis an die der Öffnungswand rechtwinklig benachbarten Wand durchgeführt. Das freie Ende der Abflußvorrichtung ist vorzugsweise sich verjüngend ausgebildet.In chimneys with a rectangular cross-section, the drainage device is advantageously carried out up to the wall adjacent to the opening wall at right angles. The free end of the drain device is preferably tapered.

Nach einer vorteilhaften Ausführungsform, bei der in die seitliche Öffnung ein Anschlußstutzen eingesetzt ist, ist dieser als Grund der Auffangvorrichtung ausgebildet.According to an advantageous embodiment, in which a connecting piece is inserted into the lateral opening, this is designed as the base of the collecting device.

Nach einer weiteren vorteilhaften Ausführungsform sind die Auffang- und Abflußvorrichtung in einer gepreßten Schornsteinmanschette oder einem gepreßten Schornsteinrohrabschnitt eingeformt.According to a further advantageous embodiment, the collecting and drainage device are molded into a pressed chimney sleeve or a pressed chimney section.

Nach Fig. 1 und 2 weist ein Schornsteinabschnitt 1 in seiner Wandung 2 eine Öffnung 3 auf. Oberhalb der Öffnung 3 ist eine Auffangvorrichtung 5 für an der Innenwandung herunterlaufendes Kondensat in Form einer in die Schornsteininnenwandung 2 eingelassenen Rille angeordnet. Nach Fig. 1 ist diese Rille bogenförmig ausgebildet, wobei die Auffangvorrichtung 5 beidseitig der Öffnung 3 in rillenartige Abflußvorrichtungen 6 übergeht. Dabei reicht die Abflußvorrichtung 6 bis zu der Wand 7, die der Öffnungswand 8 rechtwinklig benachbart ist. Das Ende der Abflußvorrichtung 6 läuft sich verjüngend aus.1 and 2, a chimney section 1 has an opening 3 in its wall 2. Arranged above the opening 3 is a collecting device 5 for condensate running down the inner wall in the form of a groove let into the inner wall 2 of the chimney. According to Fig. 1, this groove is arcuate, the collecting device 5 merging on both sides of the opening 3 into groove-like drainage devices 6. The drain device 6 extends to the wall 7 which is adjacent to the opening wall 8 at right angles. The end of the drain device 6 tapers off.

Bei der Ausführungsform nach Fig. 2 ist die Auffang- und Abflußvorrichtung 5, 6 dachartig zu beiden Seiten der Öffnung geneigt ausgebildet.2 is the Collection and drainage device 5, 6 roof-shaped inclined to both sides of the opening.

In Fig. 3 und 4 ist die Vorrichtung entsprechend Fig. 1 nochmals im Schnitt dargestellt, wobei wiederum erkennbar ist, daß die Abflußvorrichtung 5 als in die Schornsteininnenwandung 2 eingelassene bogenförmig sich nach unten neigende Rille ausgebildet ist. Diese Rille befindet sich sowohl in der Öffnungswand 8 als auch in den der Öffnungswand rechtwinklig benachbarten Wänden 7. Somit wird das in der Auffangvorrichtung 5 aufgefangene Kondensat von der seitlichen Offnung 3 an die Stellen der Innenwandung abgeleitet, von denen es nach unten abfließen kann, ohne daß an den entsprechenden kritischen Stellen des Schornsteins Schäden auftreten.3 and 4, the device according to FIG. 1 is shown again in section, again showing that the drain device 5 is designed as an arcuate, downwardly sloping groove embedded in the chimney inner wall 2. This groove is located both in the opening wall 8 and in the walls 7 adjacent to the opening wall at right angles. Thus, the condensate collected in the collecting device 5 is drained from the lateral opening 3 to the locations of the inner wall from which it can flow downwards without that damage occurs at the relevant critical points of the chimney.

Während in den Fig. 3 und 4 die Anordnung bei einer rechteckigen seitlichen Öffnung, wie sie beispielsweise bei einer verschließbaren Reinigungsöffnung gegeben ist, gezeigt ist, ist in den Fig. 5 und 6 eine Ausführungsform dargestellt, bei der ein Anschlußstutzen 4 vorgesehen ist, über den ein seitliches Verbindungsrohr an den Schornstein anschließbar ist.3 and 4, the arrangement with a rectangular side opening, such as is given, for example, with a closable cleaning opening, is shown in FIGS. 5 and 6, an embodiment in which a connecting piece 4 is provided over a side connecting pipe can be connected to the chimney.

Bei einer Ausführungsform nach den Fig. 7 und 8 ist die Oberseite eines in die Öffnung 3 eingesetzten Anschlußstutzens 4 als Grund 9 für die Auffangvorrichtung 5 ausgebildet.In an embodiment according to FIGS. 7 and 8, the top of a connection piece 4 inserted into the opening 3 is designed as a base 9 for the collecting device 5.

Bei der Ausführungsform nach den Fig. 9 und 10 befindet sich um den Anschlußstutzen 4 in der Innenwandung 2 eine umlaufende Rille 10, durch die oberhalb der Öffnung 3 eine Tropfnase 11 gebildet wird. Durch diese Tropfnase 11 wird das Kondensat in den Oberteil der Rille 10 als Auffangvorrichtung gebracht und von hier aus um die Öffnung 3 herum ebenfalls als Abflußrille nach unten geführt.In the embodiment according to FIGS. 9 and 10 there is a circumferential groove 10 around the connecting piece 4 in the inner wall 2, through which a drip nose 11 is formed above the opening 3. Through this drip nose 11, the condensate is brought into the upper part of the groove 10 as a collecting device and from here around the opening 3 also as a drain groove down.

Bei der Ausführungsform nach den Fig. 11 und 12 ist die Auffang- und Abflußvorrichtung in einer gepreßten Schornsteinmanschette 12 eingeformt.In the embodiment according to FIGS. 11 and 12, the collecting and drainage device is molded into a pressed chimney collar 12.

Bei der Ausführungsform nach den Fig. 13 und 14 ist an der Schornsteininnenwandung 2 eine Abflußrinne 13 vorgesehen, die ebenso wie die Rille nach den anderen Ausführungsformen dazu dient, das von oben im Schornstein herabfließendes Kondensat aufzufangen und von der seitlichen Öffnung 3 abzuführen.In the embodiment according to FIGS. 13 and 14, a drainage channel 13 is provided on the chimney inner wall 2, which, like the groove according to the other embodiments, serves to collect the condensate flowing down from the top of the chimney and to discharge it from the side opening 3.
