Abstract
Description
Die Erfindung bezieht sich auf eine Wärmezelle gemäß dem Oberbegriff des unabhängigen Anspruches.The invention relates to a heat cell according to the preamble of the independent Claim.
Bei Wärmezellen von Heizgeräten gemäß dem Stande der Technik ist die Strömungssicherung als ein umfangsgeschlossener Bauteil ausgebildet, die auf den Wärmetauscher gesetzt ist. Eine solche Wärmezelle ist aus EP-A-857925 bekannt.In heat cells of heaters according to the prior art is the Flow fuse formed as a circumferentially closed component, which on the Heat exchanger is set. Such a heat cell is out EP-A-857925 is known.
Bekannte Heizschächte weisen eine demontierbare Seitenwand auf, damit z.B. die Brenneroberseite und die Wärmetauscherunterseite nach Abnahme dieser Seitenwand gesäubert werden können. Eine Säuberung der Wärmetauscheroberseite ist jedoch nur möglich, wenn die komplette Strömungssicherung oder der Wärmetauscher entfernt wird. Dies ist jedoch mit einem sehr erheblichen Montageaufwand verbunden, wobei bei einer Demontage des Wärmetauschers eine an diesen angeschlossene Raumheizung entleert werden muß.Known heating ducts have a removable side wall, so that e.g. the Burner top and the heat exchanger bottom after removal of this side wall can be cleaned. However, a cleaning of the heat exchanger top is only possible if the complete flow safety device or the heat exchanger is removed. However, this is associated with a very considerable installation effort, with a Disassembly of the heat exchanger empties a connected to this room heating must become.
Ziel der Erfindung ist es, diese Nachteile zu vermeiden und eine Wärmezelle der eingangs erwähnten Art vorzuschlagen, die sich durch ein hohes Maß an Wartungsfreundlichkeit auszeichnet und insbesondere auf einfache Weise eine Reinigung des Wärmetauschers ermöglicht. The aim of the invention is to avoid these disadvantages and a heat cell of the beginning mentioned type, which is characterized by a high degree of serviceability characterized and in particular a simple way of cleaning the heat exchanger allows.
Erfindungsgemäß wird dies bei einer Wärmezelle der eingangs erwähnten Art durch kennzeichnenden Merkmale des unabhängigen Anspruches erreicht.According to the invention this is in a heat cell of the type mentioned by characterizing features of the independent claim achieved.
Durch die vorgeschlagenen Maßnahmen ist es auf einfache Weise möglich durch Abnahme der demontierbaren Einheit sowohl den Brenner als auch den Wärmetauscher zu reinigen, da diese Teile gut zugänglich sind. Dabei ist es auch möglich sowohl die Unter- wie auch die Oberseite des Wärmetauschers zu reinigen.By the proposed measures, it is easily possible by acceptance the removable unit to clean both the burner and the heat exchanger, because these parts are easily accessible. It is also possible both the lower and the Clean the top of the heat exchanger.
Durch die Maßnahmen gemäß dem Anspruch 2 ergibt sich der Vorteil einer in konstruktiver
Hinsicht sehr einfachen Lösung. Außerdem kann die demontierbare Einheit sehr einfach
montiert und demontiert werden.The measures according to
Durch die Merkmale des Anspruches 3 ergibt sich der Vorteil, daß die demontierbare Einheit
bei der Montage sehr einfach in die vorgesehene Position gebracht werden kann.Due to the features of
Dabei ist es vorteilhaft die Merkmale des Anspruches 4 vorzusehen, wodurch die Lage der
demontierbaren Einheit bei deren Montage sehr einfach festgelegt werden kann.It is advantageous to provide the features of
Durch die Merkmale des Anspruches 6 kann die Strömung der Abgase sehr einfach beeinflußt werden, wobei sich bei montierter Einheit in strömungstechnischer Hinsicht praktisch kein Unterschied zu einer Strömungssicherung nach dem Stand der Technik ergibt, die umfangsgeschlossen ausgebildet ist.Due to the features of claim 6, the flow of exhaust gases can be very simple be influenced, with mounted unit in fluidic terms practically no difference to a flow safety device according to the prior art, the circumferentially closed is formed.

angeordnete Strömungssicherung 3 ist die über eine Rückwand 12 mit dem Heizschacht 14
verbunden. Dabei ist die Rückwand 12 der Strömungssicherung 3 zweckmäßigerweise mit
der Rückwand 16 des Heizschachtes 14 verbunden, oder sind aus einem Blechteil gefertigt.The
Die Strömungssicherung 3 schließt nach oben mit dem Abgasanschluß 5 ab und besitzt
seitliche Öffnungen 17. Nach vorne ist die Strömungssicherung 3 durch die Vorderwand 11
abgeschlossen.The
Die demontierbare Vorderwand 10 des Heizschachtes 14 und die demontierbare
Vorderwand 11 der Strömungssicherung 3 bilden erfindungsgemäß eine Einheit 4. Diese
Einheit 4 verfügt ferner über Strömungsleitbleche 9, die im wesentlichen senkrecht von den
Vorderwänden 10, 11 abstehen und einen Anschlag 6, der Einrastnasen 7 aufweist. The removable
Im montierten Zustand liegt der Anschlag 6 an der Rückwand 12 der Strömungssicherung 3
an, wobei die Einrastnasen 7 in Einrastkerben 8 der Rückwand 12 einrasten. Die Einheit 4 ist
im montierten Zustand mit den Seitenwänden 15 verschraubt.In the assembled state, the stop 6 is located on the
Beim Betrieb des Heizgerätes verbrennt oberhalb des Brenners 1 ein Brenngas-LuftGemisch.
Die heißen Abgase geben an den Wärmetauscher 2 Wärme ab und erwärmen
dabei das diesen durchströmende Wasser und kühlen sich dabei ab. Die abgekühlten
Abgase strömen an den Strömungsleitblechen 9 vorbei zur Mitte der Strömungssicherung 3
und gelangen anschließend über den Abgasanschluß 5 in den Kamin.During operation of the heater burns above the
Bei einem Stau im Kamin oder Rückströmungen aus dem Kamin gelangen die Gase durch
die Öffnungen 17 in den Aufstellraum, wobei Strömungfühler vorgesehen sind, die in einem
solchen Fall für eine Abschaltung des Brenners 1 sorgen..When there is a build-up in the chimney or backflow from the chimney, the gases pass through
the
Nach Demontage der Verbindungsschrauben, die zur Verbindung der Einheit 4 mit den
Seitenwänden 15 vorgesehen sind, kann die Einheit aus der Wärmezelle gezogen werden.
Danach sind sowohl der Brenner 1, wie auch der Wärmetauscher 2 sehr gut zugänglich und
können einfach gereinigt werden.After disassembling the connecting bolts used to connect the
