Description

Die Erfindung betrifft einen Ofen nach dem Oberbegriff des Anspruchs 1.The invention relates to an oven according to the preamble of claim 1.

Dererlei Öfen werden in der Regel im häuslichen Bereich eingesetzt und dienen der Verbrennung von Holz. Auch wenn solche Öfen häufig in erster Linie deswegen in einem Haus eingesetzt werden, weil deren Wärme als sehr behaglich empfunden wird, so können diese Öfen dennoch einen beträchtlichen Beitrag zur Erwärmung eines oder mehrerer Zimmer auch in einem modernen Haus leisten. Um diese Aufgabe gut erfüllen zu können, muss der Ofen zum einen den Energieinhalt des in ihm verbrannten Holzes möglichst effizient ausnutzen und zum anderen sollte die Wärmeabgabe möglichst langsam geschehen, damit zur Erhaltung einer angenehmen Raumtemperatur möglichst selten Brennmaterial nachgelegt werden muss, vorzugsweise nur ein- oder zweimal am Tag.Such ovens are generally used and used in the home the burning of wood. Even if such stoves are often primarily because of this be used in a house because its warmth is very comfortable is felt, these stoves can still make a significant contribution for heating one or more rooms in a modern house Afford. In order to be able to perform this task well, the furnace must firstly use the energy content of the wood burned in it as efficiently as possible and on the other hand, the heat should be released as slowly as possible, so to maintain a comfortable room temperature as little as possible must be refilled, preferably only once or twice a day.

Um die oben dargestellten Ziele zu erreichen, sind gattungsgemäße Öfen zweischalig aufgebaut, nämlich mit einer Außenwandung, die letztendlich die Wärme über Strahlung und Konvektion an die zu erwärmende Raumluft abgibt und einer Brennraumwandung, die sich innerhalb der Außenwandung befindet, und welche wiederum den Brennraum umgibt. Stellenweise können hierbei die Außenwandung und die Brennraumwandung zusammenfallen, dies ist in der Regel beispielsweise bei der Tür der Fall, durch welche Holz in den Brennraum gelegt werden kann.In order to achieve the goals outlined above, generic ovens have two shells built up, namely with an outer wall, which ultimately the heat emits to the room air to be heated via radiation and convection and a combustion chamber wall, which is located within the outer wall, and which in turn surrounds the combustion chamber. In some cases, the outer wall and the combustion chamber wall collapse, this is usually For example, in the case of the door through which wood in the combustion chamber can be placed.

Die bei der Verbrennung entstehenden Heizgase verlassen den Brennraum in einem oberen Abschnitt und gelangen dann in einen Heizgaskanal, der sich zwischen der Brennraumwandung und einer seitlichen Außenwandung nach unten erstreckt, wo er in einem Anschluss für das Ofenrohr endet. Durch diese Heizgasführung gelingt ein guter Übertrag der Verbrennungswärme auf die Außenwandung.The heating gases generated during combustion leave the combustion chamber in an upper section and then get into a heating gas duct, which is between the combustion chamber wall and a lateral outer wall extends below where it ends in a connection for the stovepipe. Through this The heating gas flow manages a good transfer of the heat of combustion to the outer wall.

Wegen seiner sehr günstigen thermischen Eigenschaften hinsichtlich Wärmeleitung und Wärmekapazität werden die oben beschriebenen Öfen vorzugsweise aus Speckstein aufgebaut. Speckstein hat jedoch den Nachteil, dass er mechanisch nicht sehr stabil ist, so dass die aus Speckstein bestehenden Brennraumwandungen relativ häufig ausgebessert oder sogar erneuert werden müssen, was neben einem erheblichen Arbeitsaufwand natürlich auch zu einem erhöhten Specksteinbedarf führt. Aus diesem Grund wäre es günstig, die Brennraumwandungen aus einem anderen Material aufzubauen, was jedoch bei den bisherigen Konstruktionen dazu führen würde, dass die Heizleistung des Ofens wesentlich verschlechtert würde.Because of its very favorable thermal properties with regard to heat conduction and heat capacity, the furnaces described above are preferred made of soapstone. However, soapstone has the disadvantage that it is mechanical is not very stable, so that the combustion chamber walls made of soapstone relatively often need to be repaired or even replaced, which in addition to a considerable amount of work naturally also leads to a leads to increased demand for soapstone. Because of this, it would be convenient to Build combustion chamber walls from a different material, but what with previous designs would lead to the heating power the furnace would deteriorate significantly.

Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, einen gattungsgemäßen Ofen dahingehend zu verbessern, dass seine Heizleistung gegenüber bisherigen Öfen verbessert wird, so dass dadurch die Möglichkeit geschaffen wird, die Brennraumwandungen aus einem anderen Material als Speckstein herzustellen, ohne dass ein wesentlicher Verlust an Heizleistung eintritt.Based on this prior art, it is an object of the invention to generic furnace to improve that its heating capacity compared to previous stoves, so that the possibility is created, the combustion chamber walls from a different material than Make soapstone without a significant loss of heating power entry.

Diese Aufgabe wird mit einem Ofen mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with an oven having the features of claim 1.

Erfindungsgemäß wird die Heizleistung dadurch verbessert, dass dem ersten Heizgaskanalabschnitt, welcher sich zwischen einer seitlichen Außenwandung und der Brennraumwandung erstreckt, ein zweiter nachfolgender Heizgaskanalabschnitt hinzugefügt wird, welcher unter dem Brennraum hindurch führt. Dadurch kann der Weg des Heizgaskanals verlängert werden, ohne die Außenabmessungen des Ofens vergrößern zu müssen. Weiterhin scheint es so zu sein, dass eine Anwärmung des Brennraumes von unten sich insgesamt positiv auf das Verbrennungs- und Wärmeabgabeverhalten des Ofens auswirkt. According to the invention, the heating power is improved in that the first Heating gas duct section, which is between a lateral outer wall and the combustion chamber wall extends, a second subsequent heating gas duct section is added, which leads under the combustion chamber. This allows the path of the heating gas duct to be extended without the external dimensions need to enlarge the oven. It still seems that way be that heating the combustion chamber from below is positive overall affects the combustion and heat emission behavior of the furnace.

Nach Anspruch 2 schließt sich an den zweiten Heizgaskanalabschnitt ein dritter Heizgaskanalabschnitt an, der sich ähnlich oder sogar symmetrisch wie der erste Heizgaskanalabschnitt zwischen Brennraumwandung und Außenwandung befindet und nach oben führt. Somit kann die gesamte Länge des Heizgaskanals im Vergleich zum Stand der Technik mehr als verdoppelt werden.According to claim 2, a third connects to the second heating gas duct section Heating gas duct section that is similar or even symmetrical to the first Heating gas duct section between the combustion chamber wall and the outer wall located and leads upwards. Thus, the entire length of the heating gas duct be more than doubled compared to the prior art.

Nach den Ansprüchen 5 und 6 ist der Ofen im wesentlichen aus zwei unterschiedlichen Materialien aufgebaut, nämlich außen aus Speckstein und die Brennraumwandung aus Schamottsteinen. Somit wird erreicht, dass der Ofen eine sehr hohe Standzeit erreicht, in der keine Reparaturarbeiten notwendig sind, und dabei eine Heizleistung erzielt, die mit denen herkömmlicher Specksteinöfen wenigstens vergleichbar ist.According to claims 5 and 6, the furnace is essentially two different Materials built up, namely from soapstone and the outside Combustion chamber wall made of firebricks. This ensures that the oven achieved a very long service life in which no repair work is necessary are, and at the same time achieve a heating output comparable to that of conventional soapstone stoves is at least comparable.

Da der Bereich unterhalb des Brennraumes nicht mehr wie bei bisherigen Öfen üblich zur Frischluftzufuhr verwendet werden kann, erfolgt die Luftzufuhr nach Anspruch 7 nun über entsprechende Luftzuführungseinrichtungen, beispielsweise Schlitze oder Löcher in der Tür oder in deren Rahmen.Since the area below the combustion chamber is no longer the same as in previous stoves can usually be used for fresh air supply, the air supply follows Claim 7 now via appropriate air supply devices, for example Slits or holes in the door or in its frame.

Weitere vorteilhafte Ausführungsformen ergeben sich aus den weiteren Unteransprüchen, sowie aus den im folgenden mit Bezug auf die Zeichnungen dargestellten Ausführungsbeispielen.Further advantageous embodiments result from the further subclaims, as well as from the following with reference to the drawings illustrated embodiments.

Figur 1 zeigt die perspektivische Darstellung eines Ofens. Die Außenwandung 10 besteht zum überwiegenden Teil aus Speckstein, wobei der größte Teil, welcher nicht aus Speckstein besteht, die Tür 15 und deren Rahmen 16 ist. Wie man später sehen wird, ist die Tür bzw. deren Rahmen hier das einzige Bauteil, das sowohl Teil der Außenwandung 10 als auch Teil der Brennraumwandung ist. Die Tür 15 oder deren Rahmen 16 verfügen über Luftzuführungseinrichtungen, beispielsweise in Form von Schlitzen, die hier jedoch nicht genauer dargestellt sind. Der effektive Durchmesser der Luftzuführungseinrichtungen kann mittels des Zulufthebels 17 geregelt werden, wobei es vorzugsweise auch eine komplett geschlossene Stellung gibt.Figure 1 shows the perspective view of an oven. The outer wall 10 consists mainly of soapstone, the largest part, which does not consist of soapstone, the door 15 and its frame 16. How you will see later, the door or its frame is the only component here, that both part of the outer wall 10 and part of the combustion chamber wall is. The door 15 or its frame 16 have air supply devices, for example in the form of slots, which are not shown here in more detail are. The effective diameter of the air supply devices can be regulated by means of the supply air lever 17, it preferably also being a completely closed position.

Weiterhin erkennt man an der rechten Außenwandung 14 zwei Ofenrohranschlüsse, die hier von den beiden Blindflanschen 41a, 42a abgedeckt sind.Furthermore, two stovepipe connections can be seen on the right outer wall 14, which are covered here by the two blind flanges 41a, 42a.

Zur Erläuterung des inneren Aufbaus des Ofens wird nun Bezug auf die Schnittzeichnungen 2 bis 8 genommen. Anhand Figur 2 kann sehr gut der zweischalige Aufbau des Ofens erkannt werden, wobei die Außenschale durch die Außenwandung 10 mit ihrer vorderen Außenwandung 11, ihrer linken Außenwandung 12, ihrer hinteren Außenwandung 13 und ihrer rechten Außenwandung 14, sowie der unteren Abschlussplatte 18 und der oberen Abschlussplatte 19 gebildet wird.To explain the internal structure of the furnace, reference is now made to the Sectional drawings 2 to 8 taken. Based on Figure 2, the Double-shell construction of the furnace can be recognized, with the outer shell through the outer wall 10 with its front outer wall 11, its left outer wall 12, its rear outer wall 13 and its right outer wall 14, and the lower end plate 18 and the upper end plate 19 is formed.

Die Brennraumwandung 20 besteht im wesentlichen aus der vorderen Brennraumwandung 21, der linken Brennraumwandung 22, der hinteren Brennraumwandung 23, der rechten Brennraumwandung 24, dem Deckel 25 und der zweilagig ausgebildeten Bodenplatte 26. Wie oben bereits dargestellt, ist die Tür 15 sowohl Teil der Außenwandung, als auch Teil der Brennraumwandung.The combustion chamber wall 20 essentially consists of the front combustion chamber wall 21, the left combustion chamber wall 22, the rear combustion chamber wall 23, the right combustion chamber wall 24, the cover 25 and the two-layer base plate 26. As already shown above, the Door 15 both part of the outer wall and part of the combustion chamber wall.

Der Brennraum B besitzt zwei Ausgänge für die Heizgase, nämlich die Durchbrechung 28, die hier im oberen Bereich der linken Brennraumwandung 22 vorgesehen ist, und durch die der Hauptteil der Heizgase aus dem Brennraum austritt. Aus Sicherheitsgründen weist der Deckel 25, der den Brennraum B nach oben hin abschließt, ein Loch 25a auf, durch den ein kleiner Teil der Heizgase in den Sammelraum S austritt. Dieses Loch 25a dient der Verhinderung von Verpuffungen und ist deshalb aus Sicherheitsgründen in der Regel notwendig. Der Querschnitt des Loches 25a ist wesentlich kleiner als der Querschnitt der Durchbrechung 28, vorzugsweise beträgt die Querschnittsfläche höchstens 10% derjenigen der Durchbrechung.The combustion chamber B has two outputs for the heating gases, namely the opening 28, which is provided here in the upper region of the left combustion chamber wall 22 and through which the main part of the heating gases from the combustion chamber exit. For safety reasons, the cover 25, which has the combustion chamber B closes at the top, a hole 25a through which a small part of the heating gases exits in the collecting room S. This hole 25a is for prevention of deflagrations and is therefore usually necessary for safety reasons. The cross section of the hole 25a is significantly smaller than the cross section of the opening 28, preferably the cross-sectional area is at most 10% of those of the breakthrough.

An die Durchbrechung 28 schließt sich der erste Heizgaskanalabschnitt 31 an, der sich senkrecht zwischen der linken Außenwandung 12 und der linken Brennraumwandung 22 erstreckt. An diesen ersten Heizgaskanalabschnitt 31 schließt sich der zweite Heizgaskanalabschnitt 32 an, der unterhalb der Bodenplatte 26 des Brennraumes verläuft. Hierzu ruht die Bodenplatte 26, die hier zweischichtig ausgebildet ist, auf den beiden Stützmauern 27, so dass zwischen diesen beiden Stützmauern 27 ein Hohlraum frei bleibt. Dies ist am besten der Figur 3 oder den Figuren 7 und 8 in Verbindung mit Figur 2 zu entnehmen.The opening 28 is followed by the first hot gas duct section 31, which is perpendicular between the left outer wall 12 and the left Combustion chamber wall 22 extends. At this first heating gas channel section 31 is followed by the second heating gas channel section 32, which is below the base plate 26 of the combustion chamber runs. For this purpose, the base plate 26 rests here is formed in two layers, on the two retaining walls 27, so that between these two retaining walls 27 a cavity remains free. This is the best 3 or FIGS. 7 and 8 in conjunction with FIG. 2.

An das Ende des zweiten Heizgaskanalabschnittes 32 schließt sich nun der dritte Heizgaskanalabschnitt an, der im wesentlichen symmetrisch zum ersten Heizgaskanalabschnitt 31 ist. Der dritte Heizgaskanalabschnitt 33 befindet sich zwischen rechter Brennraumwandung 24 und rechter Außenwandung 14. Der dritte Heizgaskanalabschnitt 33 endet im Sammelraum S oberhalb der Brennkammer B. Weiterhin sind die beiden Ofenrohranschlüsse 41 und 42 mit dem dritten Heizgaskanalabschnitt 33 verbunden. Je nach örtlichen Gegebenheiten kann das Ofenrohr, mittels dessen die Heizgase nach außen abgeführt werden, an einen der beiden Ofenrohranschlüsse 41,42 angeschlossen werden, wobei der jeweils andere Ofenrohranschluss mit einem Blindflansch abgedeckt bleibt.At the end of the second heating gas channel section 32, the now closes third heating gas channel section, which is substantially symmetrical to the first Heating gas channel section 31. The third hot gas duct section 33 is located between the right combustion chamber wall 24 and the right outer wall 14. The third heating gas duct section 33 ends in the collecting space S above the combustion chamber B. Furthermore, the two stovepipe connections 41 and 42 with the third hot gas duct section 33 connected. Depending on local conditions can the stovepipe, by means of which the heating gases are discharged to the outside, can be connected to one of the two stovepipe connections 41, 42, whereby the other stovepipe connection remains covered with a blind flange.

Im vorliegenden Ausführungsbeispiel wird das Ofenrohr bevorzugt am oberen Ofenrohranschluss 42 angeschlossen. Anderenfalls ist in der Regel dafür Sorge zu tragen, dass der aus dem Loch 25a kommende Heizgasstrom ungehindert abziehen kann, um Verpuffungen sicher zu verhindern. Dies könnte beispielsweise durch Anschluss eines zweiten, kleiner dimensionierten Ofenrohres geschehen.In the present exemplary embodiment, the stovepipe is preferably at the top Stovepipe connection 42 connected. Otherwise, care is usually taken to bear that the heating gas flow coming out of the hole 25a unhindered can pull off to safely prevent deflagration. For example by connecting a second, smaller-sized stovepipe.

Mit dem Bezugszeichen I ist in den Figuren 4 bis 8 die bevorzugte Einbaulage von Isolationsmaterial gekennzeichnet. Weiterhin sieht man anhand der Figuren 4 bis 8, dass die Außenwandung 10 im Bereich des 1. und 3. Heizgakanalabschnittes 31, 33 zweilagig aus zwei Schichten Speckstein aufgebaut ist.The preferred installation position is the reference number I in FIGS. 4 to 8 characterized by insulation material. Furthermore you can see from the figures 4 to 8 that the outer wall 10 in the area of the 1st and 3rd Heizgakanalabschnittes 31, 33 is built up in two layers from two layers of soapstone.

Die Funktionsweise des Ofens wird nun mit Bezug auf die Figuren 9 und 10 erläutert. In diesem Ausführungsbeispiel ist das Ofenrohr R am oberen Ofenrohranschluss 42 angeschlossen.The operation of the furnace will now be described with reference to FIGS. 9 and 10 explained. In this exemplary embodiment, the stovepipe R is at the top stovepipe connection 42 connected.

Im Brennraum B verbrennen Holzscheite, wobei die Zuluft durch Luftzuführungseinrichtungen in der Tür oder im Türrahmen zuströmt. Die heißen Heizgase steigen nach oben und verlassen den Brennraum zu einem geringen Teil durch das Loch 25a im Deckel 25 und gelangen von dort in den Sammelraum S. Der Großteil der Heizgase gelangt durch die Durchbrechung 28 in den ersten Heizgaskanalabschnitt 31 und wird in diesem nach unten geführt. Im weiteren strömen die Heizgase unterhalb des Brennraumes B durch den zweiten Heizgaskanalabschnitt 32, über welchen sie in den dritten Heizgaskanalabschnitt 33 gelangen, in dem sie nach oben steigen. An seinem Ende vereinigt sich der dritte Heizgaskanalabschnitt 33 mit dem Sammelraum S, wo der Hauptheizgasstrom mit dem Nebenheizgasstrom, der durch das Loch 25a tritt, vereinigt wird. Anschließend tritt der Gesamtstrom der Heizgase durch den oberen Ofenrohranschluss 42 in das Ofenrohr R. Logs burn in combustion chamber B, with the supply air being supplied by air supply devices flows in the door or in the door frame. The hot heating gases rise to the top and leave the combustion chamber to a small extent through the hole 25a in the lid 25 and from there into the collecting space S. The majority of the heating gases pass through the opening 28 in the first Heating gas channel section 31 and is guided downwards in this. In the further the heating gases flow below the combustion chamber B through the second heating gas duct section 32, via which they enter the third heating gas channel section 33 get there by climbing up. At the end of the third heating gas duct section 33 with the collecting space S, where the main heating gas flow combined with the auxiliary heating gas flow passing through the hole 25a becomes. Then the total flow of the heating gases passes through the upper stovepipe connection 42 into the stovepipe R.

Wie man sieht, ist der Gesamtweg der Heizgase durch den Ofen sehr lang, wodurch eine sehr gute Wärmeausnutzung und Wärmeübertragung erreicht wird. Hierdurch wird es möglich, die Brennraumwandung 20 - mit Ausnahme der Tür 15 und des Türrahmens 16 - aus Schamottsteinen zu fertigen, ohne im Vergleich zu reinen Specksteinöfen einen Verlust an Heizleistung hinnehmen zu müssen. Von dieser Möglichkeit wird im vorliegenden Ausführungsbeispiel auch Gebrauch gemacht. Die Außenwandung 10 besteht vorzugsweise im wesentlichen aus Speckstein.As you can see, the total path of the heating gases through the furnace is very long, which means very good heat utilization and heat transfer is achieved. This enables the combustion chamber wall 20 - with the exception of the door 15 and the door frame 16 - made of firebrick, without comparison for pure soapstone stoves there is a loss of heating power have to.
