Description

Die Erfindung betrifft eine geschlossene Feuerstätte nach dem Oberbegriff des Anspruchs 1.The invention relates to a closed fireplace according to the preamble of claim 1.

Geschlossene Feuerstätten sind in ihrer Bauform als Kamine, Kaminöfen oder Kamineinsätze konzipiert. Diese dienen dem Verbrennen von Feststoffen wie Holz, Briketts oder dergleichen zur Beheizung von Räumen.Closed fireplaces are designed in the form of fireplaces, stoves or fireplace inserts. These are used to burn solids such as wood, briquettes or the like to heat rooms.

Entsprechend den einschlägigen Vorschriften weist eine solche Feuerstätte eine den Brennraum verschließende Tür, in Form einer Schwenk- oder Schiebetür, eine Brennluftzufuhr sowie eine Abgasführung auf, die jeweils mit dem Brennraum in Wirkverbindung stehen. Dabei sind sowohl die Brennluftzufuhr, um Frischluft zuzuführen, wie auch die Abgasführung mit der Außenumgebung verbunden.According to the relevant regulations, such a fireplace has a door closing the combustion chamber, in the form of a pivoting or sliding door, a combustion air supply and an exhaust gas duct, each of which is operatively connected to the combustion chamber. Both the combustion air supply to supply fresh air and the exhaust gas routing are connected to the outside environment.

Für den Betrieb einer solchen Feuerstätte ist die Bevorratung von Festbrennstoffen üblich, was einen entsprechenden Lagerraum voraussetzt, wobei dieser vielfach nicht in einer ausreichenden Größe vorhanden ist. Auch die Beschaffung des Festbrennstoffes, insbesondere des Holzes, das bevorzugt als Holzscheite vorliegt, gestaltet sich aufwändig und umständlich.The storage of solid fuels is common for the operation of such a fireplace, which requires a corresponding storage space, which is often not available in a sufficient size. The procurement of solid fuel, in particular the wood, which is preferably in the form of logs, is also complex and cumbersome.

Darüber hinaus führt die Verbrennung der Festbrennstoffe zu einer Verschmutzung des Brennraumes durch Rußablagerung und Aschebildung sowie einem Verrußen einer Glasscheibe, wenn diese als Sichtfenster der Tür vorhanden ist. Je nach Nutzung der Feuerstätte ist die Entsorgung des Ascheanfalls mehr oder weniger häufig vorzunehmen, in jedem Fall jedoch mit einem entsprechenden Arbeitsaufwand verbunden.In addition, the combustion of the solid fuels leads to contamination of the combustion chamber by soot deposition and ash formation, as well as sooting of a glass pane if it is present as a viewing window of the door. Depending on the use of the fireplace, the ash is disposed of more or less frequently, but in any case involves a corresponding amount of work.

Bekannt sind weiterhin vornehmlich in Wohnräumen betriebene Feuerstätten, die, abweichend von der Gattung, nicht mit Festbrennstoffen beheizt werden, sondern mit einem Flüssigbrennstoff, beispielsweise Alkohol, wie Ethanol oder dergleichen.Also known are primarily fireplaces operated in living rooms, which, in deviation from the genus, are not heated with solid fuels, but with a liquid fuel, for example alcohol, such as ethanol or the like.

Vorteile dieser Feuerstätten gegenüber denen mit Festbrennstoffen betriebenen ergeben sich aus der einfacheren Lagerung und Bereitstellung des Flüssigbrennstoffs sowie einem rückstandsfreien Abbrand, also keinem Ascheanfall und erheblich verminderter Verschmutzung, was die Reinigung der Feuerstätte deutlich begünstigt.Advantages of these fireplaces compared to those operated with solid fuels result from the easier storage and provision of the liquid fuel as well as residue-free combustion, i.e. no ash and significantly reduced pollution, which significantly improves the cleaning of the fireplace.

Allerdings weisen diese Feuerstätten keine Abgasführung auf, woraus sich deutliche Nachteile bei deren Betrieb ergeben. Eine Belüftung des Raumes ist deshalb zwingend, weil die Verbrennungsgase unmittelbar in den Raum abgegeben werden.However, these fireplaces have no flue gas routing, which results in significant disadvantages in their operation. Ventilation of the room is imperative because the combustion gases are released directly into the room.

Dies schafft jedoch insoweit Probleme als eine Frischluftzufuhr in den Raum unerlässlich ist, was durch mehr oder weniger häufiges Öffnen von Fenstern oder Außentüren erfolgt.However, this creates problems insofar as a fresh air supply into the room is essential, which is done by opening windows or external doors more or less frequently.

Der gewünschte Heizeffekt dieser Feuerstätte wird damit konterkariert. D.h., insbesondere hinsichtlich der Energiebilanz entspricht der Betrieb dieser Feuerstätte nicht den gestellten und gewünschten Anforderungen.This counteracts the desired heating effect of this fireplace. That means, especially with regard to the energy balance, the operation of this fireplace does not meet the required and desired requirements.

In der US 2 615 635 A ist eine geschlossene Feuerstätte offenbart zur Beheizung eines Gewächs- oder Treibhauses oder eines Wohnhauses, insbesondere eines Einfamilienhauses.In the US 2,615,635 A is a closed fireplace disclosed for heating a greenhouse or greenhouse or a house, in particular a single-family house.

Zwar weist diese Feuerstätte einen Brennraum auf, dieser ist jedoch, entgegen der Gattung, nicht durch eine Tür verschließbar, so dass ein unmittelbarer Zugriff auf den Brennraum nicht möglich ist.Although this fireplace has a combustion chamber, this, contrary to the genre, cannot be closed by a door, so that direct access to the combustion chamber is not possible.

Des Weiteren sind aus der GB 1911/11390 A sowie der US 2005/0175950 A1 Gasbrenner bekannt.Furthermore, from the GB 1911/11390 A as well as the US 2005/0175950 A1 Gas burner known.

In der US 4 373 905 A ist eine gattungsgemäße Feuerstätte gemäß dem Oberbegriff des ersten Anspruchs offenbart, bei der die Zündung des flüssigen Brennstoffs in Form von Altöl durch entzündetes Papier erfolgt, das durch eine Klappe zu einer Brennschale gebracht wird.In the US 4,373,905 A is a generic fireplace according to the preamble of the first claim is disclosed, in which the ignition of the liquid fuel in the form of waste oil is carried out by ignited paper, which is brought to a brazier by a flap.

In der US 4 351 316 A ist ebenfalls eine Feuerstätte thematisiert, mit der vorzugsweise Altöl verbrennbar ist, wobei diese Literatur keinen Hinweis auf die Art der Zündung des Brennstoffs gibt.In the US 4,351,316 A is also a fireplace with which waste oil is preferably combustible, but this literature gives no indication of the type of ignition of the fuel.

Schließlich zeigt und beschreibt die DE 11 53 503 B eine Feuerstätte, bei der der flüssige Brennstoff mittels einer elektrischen Zündvorrichtung gezündet wird.Finally, the shows and describes DE 11 53 503 B a fireplace in which the liquid fuel is ignited by means of an electrical ignition device.

Der Erfindung liegt die Aufgabe zugrunde, eine Feuerstätte der gattungsgemäßen Art so weiterzuentwickeln, dass ihr Betrieb insgesamt deutlich einfacher wird.The invention has for its object to develop a fireplace of the generic type so that its operation is significantly easier overall.

Diese Aufgabe wird durch eine Feuerstätte mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a fireplace with the features of claim 1.

Durch die Erfindung ergibt sich eine Kombination der Vorteile einer mit Festbrennstoff betriebenen Feuerstätte mit den Vorteilen einer mit Flüssigbrennstoff betriebenen. So ist beispielsweise die Bevorratung mit Brennstoff deutlich einfacher als die von Festbrennstoffen, insbesondere Holz, ebenso die Beschaffung des Brennstoffs, wobei der den Flüssigbrennstoff aufnehmende Behälter, an den, gemäß der Erfindung ein Brenner angeschlossen ist, austausch- und wiederauffüllbar ist. Die Lagerung mehrerer solcher Behälter zur Bevorratung gestaltet sich dabei einfach und vor allem platzsparend.The invention results in a combination of the advantages of a fireplace operated with solid fuel and the advantages of a fireplace operated with liquid fuel. For example, the storage of fuel is much easier than that of solid fuels, in particular wood, as is the procurement of the fuel, the container holding the liquid fuel, to which, according to the invention, a burner is connected, can be replaced and refilled. The storage of several such containers for storage is simple and, above all, space-saving.

Eine Verschmutzung des Brennraumes ergibt sich nunmehr nicht oder in einem vernachlässigbar geringen Umfang. Reinigungsarbeiten, wie ein Säubern des Brennraumes, ggf. einer Türglasscheibe und Ascheentsorgung entfallen komplett, so dass der Betrieb der Feuerstätte insgesamt wesentlich vereinfacht ist.The combustion chamber is now not contaminated or to a negligible extent. Cleaning work, such as cleaning the combustion chamber, possibly a door glass pane and ash disposal are completely eliminated, so that the operation of the fireplace is considerably simplified overall.

Andererseits wird das bei der Verbrennung entstehende Abgas abgeführt, üblicherweise in einen Schornstein, während die zur Verbrennung erforderliche Frischluft nach einem weiteren Gedanken der Erfindung aus der äußeren Umgebung bezogen wird. Denkbar ist jedoch auch, die Verbrennungsluft, wie bei beispielsweise gasbetriebenen Öfen, unmittelbar aus dem Raum zu beziehen.On the other hand, the exhaust gas generated during the combustion is removed, usually into a chimney, while the fresh air required for the combustion is obtained from the external environment according to a further concept of the invention. However, it is also conceivable to obtain the combustion air directly from the room, as is the case, for example, with gas-powered stoves.

Nach einem weiteren Gedanken der Erfindung ist der den Flüssigbrennstoff aufnehmende Behälter unterhalb des Brenners angeordnet, der praktisch den Boden des Brennraumes bildet und bevorzugt mit einem Brenngitter abgedeckt ist.According to a further idea of the invention, the container holding the liquid fuel is arranged below the burner, which practically forms the bottom of the combustion chamber and is preferably covered with a combustion grate.

Gleichfalls im Bauraum unterhalb des Brenners ist eine Pumpe vorgesehen, mittels derer Flüssigbrennstoff in eine Brennschale des Brenners gefördert wird.A pump is also provided in the installation space below the burner, by means of which liquid fuel is conveyed into a burner bowl of the burner.

Mittels des Brenngitters werden getrennte Zonen geschaffen und zwar unterhalb des Brenngitters eine frühe Primärbrennzone und oberhalb des Brenngitters eine späte Primärbrennzone. Unterhalb der frühen Primärbrennzone ist nach einem weiteren Gedanken eine Vorwärm-/Vergasungszone angeordnet.Separate zones are created by means of the fuel grate, namely an early primary combustion zone below the fuel grate and a late primary combustion zone above the fuel grate. According to another idea, a preheating / gasification zone is arranged below the early primary combustion zone.

Die Zündung des Brenners erfolgt durch ein thermoelektrisches Zündelement, alternativ durch ein piezoelektrisches Zündelement. Darüber hinaus ist die Brennschale mit einem Überlauf versehen, der in den Brennstoffbehälter mündet und der einen Flammenrückschlagschutz aufweist.The burner is ignited by a thermoelectric ignition element, alternatively by a piezoelectric ignition element. In addition, the brazier is provided with an overflow which opens into the fuel tank and which has a flame retardant protection.

Ferner kann ein Spülluft-Ventilator vorgesehen sein, mit dem Brennstoffdämpfe vor dem Zündvorgang beseitigt werden, wobei dieser Spülluft-Ventilator mittels einer Druckdose überwacht wird.Furthermore, a purge air fan can be provided, with which fuel vapors are eliminated before the ignition process, this purge air fan being monitored by means of a pressure cell.

Im Übrigen kann die Feuerstätte oberhalb des Brennraumes mit Wärmeübertragern versehen sein, durch die die Heizwirkung optimiert wird.In addition, the fireplace above the combustion chamber can be equipped with heat exchangers, which optimize the heating effect.

Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous developments of the invention are characterized in the subclaims.

Im unteren Endbereich ist ein Stutzen einer Brennluftzuführung 4 angeordnet über die Raumluft als Brennluft dem Brennraum 6 zugeführt wird. Optional ist an die Brennluftzuführung 4 eine Frischluftleitung anschließbar, die mit der Außenluft in Verbindung steht.A nozzle of a combustion air supply 4 is arranged in the lower end region, via which room air is supplied to the combustion chamber 6 as combustion air. A fresh air line, which is connected to the outside air, can optionally be connected to the combustion air supply 4.

Über Luftschlitze 5, die in dem der Brennluftzuführung 4 benachbarten Bereich im Gehäuse 1 angeordnet sind, wird Konvektionsluft in das Gehäuse 1 geführt. Ebenso wie die Brennluftzuführung 4 steht eine Abgasführung 3 mit dem Brennraum 6 in Wirkverbindung, wobei die Abgasführung 3 in jedem Fall, beispielsweise an einen Schornstein angeschlossen, mit der Außenluft in Verbindung steht.Convection air is guided into the housing 1 via air slots 5, which are arranged in the area adjacent to the combustion air supply 4 in the housing 1. Like the combustion air supply 4, an exhaust gas duct 3 is operatively connected to the combustion chamber 6, the exhaust gas duct 3 being connected to the outside air in any case, for example connected to a chimney.

Am Boden des Brennraumes 6 ist ein Brenner 7 angeordnet, der als Einzelheit in der Fig. 5 abgebildet ist.At the bottom of the combustion chamber 6, a burner 7 is arranged, which as a detail in the Fig. 5 is shown.

Unterhalb des Brenners 7 ist im Gehäuse 1 ein Behälter 8 für einen Flüssigbrennstoff positioniert, beispielsweise Alkohol wie Ethanol oder dergleichen.A container 8 for a liquid fuel, for example alcohol such as ethanol or the like, is positioned below the burner 7 in the housing 1.

Über eine Pumpe 10 ist der Flüssigbrennstoff zum Brenner 7 führbar. Mittels eines Gebläses 9 sind Brennstoffdämpfe, die sich in der Zuleitung zum Brenner 7 angesammelt haben, vor einer Zündung zu entfernen, wobei das Gebläse 9 mittels einer Druckdose überwacht werden kann.The liquid fuel can be fed to the burner 7 via a pump 10. By means of a blower 9, fuel vapors that have accumulated in the feed line to the burner 7 are to be removed before ignition, wherein the blower 9 can be monitored by means of a pressure cell.

Oberhalb des Brennraumes 6 sind im Übrigen Wärmeübertrager 17 angeordnet, zur Erhöhung der Heizeffizienz.Incidentally, heat exchangers 17 are arranged above the combustion chamber 6, in order to increase the heating efficiency.

In der Fig. 5 ist der Brenner 7 als Einzelheit dargestellt. Dabei ist eine Brennschale 11 ausgebildet, die in zwei übereinander liegende Zonen durch ein Brenngitter 12 unterteilt ist und zwar in eine untere frühe Primärbrennzone 14 und eine obere späte Primärbrennzone 16, wobei der späteren Primärbrennzone 16 ein Zünder 13 zugeordnet ist.In the Fig. 5 the burner 7 is shown as a detail. In this case, a brazier 11 is formed, which is divided into two superimposed zones by a firing grid 12, namely into a lower early primary combustion zone 14 and an upper late primary combustion zone 16, an igniter 13 being assigned to the later primary combustion zone 16.

Unterhalb der frühen Primärbrennzone 14 ist eine Vorwärm-/Vergasungszone 15 angeordnet. Der Brenner 7 ist im Übrigen auch in der Fig. 4 erkennbar, die eine Draufsicht auf das Brenngitter 12 und den Zünder 13 wiedergibt.A preheating / gasification zone 15 is arranged below the early primary combustion zone 14. The burner 7 is also in the Fig. 4 recognizable, which shows a top view of the fuel grille 12 and the igniter 13.

Der Behälter 8 ist im Übrigen aus dem Gehäuse 1 entnehmbar, wobei hierzu vorzugsweise im Gehäuse 1 eine Klappe vorgesehen ist. Je nach Ausführungsvariante der Feuerstätte können ein oder mehrere Behälter 8 deponiert sein, wobei diese jeweils bei Entleerung gegen wiederbefüllte Behälter 8 austauschbar sind.The container 8 can moreover be removed from the housing 1, a flap preferably being provided for this purpose in the housing 1.
