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 their design as fireplaces, stoves or fireplace inserts. These are used to burn solids such as wood, briquettes or the like for heating 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 on the combustion chamber occlusive door, in the form of a swivel or sliding door, a combustion air supply and exhaust system, which are in each case in operative connection with the combustion chamber. Both the combustion air supply to supply fresh air, as well as the exhaust system with the outside environment are connected.

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.For the operation of such a fireplace, the storage of solid fuels is common, which requires a corresponding storage space, which is often not available in a sufficient size. Also, the procurement of solid fuel, especially the wood, which is preferably present as logs, designed consuming 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 burning 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 when it is present as a window of the door. Depending on the use of the fireplace, the disposal of the ash is more or less frequent, but in any case associated with 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.Further known are mainly operated in living spaces fireplaces, which, notwithstanding the genus, are not heated with solid fuels, but with a liquid fuel, such as 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 fueled by solid fuels result from the simpler storage and provision of the liquid fuel and a residue-free combustion, so no ash attack and significantly reduced pollution, which promotes the cleaning of the fireplace significantly.

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 exhaust system, resulting in significant disadvantages in their operation. Aeration of the room is imperative because the combustion gases are discharged 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 in that a fresh air supply into the room is essential, which is done by more or less frequent opening of windows or external doors.

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.The desired heating effect of this fireplace is thus counteracted. That is, in particular with regard to the energy balance, the operation of this fireplace does not meet the desired 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 Pat. No. 2,615,635 A is a closed fireplace revealed for heating a greenhouse or greenhouse or a residential building, especially a family home.

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 is, however, contrary to the genus, not closed by a door, so that immediate 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.

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 further develop a fireplace of the generic type so that their operation is significantly easier.

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 provides a combination of the advantages of a solid fuel fired fireplace with the advantages of liquid fueled operation. Thus, for example, the storage of fuel is much easier than that of solid fuels, especially wood, as well as the procurement of the fuel, wherein the liquid fuel receiving container, to which, according to the invention, a burner is connected, interchangeable and refillable. The storage of several such containers for storage is designed simply 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.Contamination of the combustion chamber is now not or to a negligible extent. Cleaning work, such as cleaning the combustion chamber, possibly a door glass pane and ash disposal completely eliminated, so that the operation of the fireplace as a whole is much easier.

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 produced in the combustion is discharged, usually in a chimney, while the fresh air required for combustion according to a further aspect of the invention is obtained from the external environment. It is also conceivable, however, to obtain the combustion air directly from the room, as in the case of gas-fired ovens, for example.

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 aspect of the invention, the container receiving the liquid fuel is arranged below the burner, which practically forms the bottom of the combustion chamber and is preferably covered with a burner grate.

Gleichfalls im Bauraum unterhalb des Brenners ist eine Pumpe vorgesehen, mittels derer Flüssigbrennstoff in eine Brennschale des Brenners gefördert wird.Likewise, in the space below the burner, a pump is provided, by means of which liquid fuel is conveyed into a combustion 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.By means of the combustion grate, separate zones are created, namely below the combustion grate an early primary combustion zone and above the combustion grate a late primary combustion zone. Below the early primary combustion zone, a preheating / gasification zone is arranged according to another idea.

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 ignition of the burner is effected by a thermoelectric ignition element, alternatively by a piezoelectric ignition element. In addition, the combustion bowl is provided with an overflow, which opens into the fuel container and has a flashback 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 scavenging air fan can be provided, are eliminated with the fuel vapors before the ignition, said purge air fan is 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.Incidentally, the fireplace can be provided above the combustion chamber with heat exchangers, through which the heating effect is optimized.

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

Optionally, a fresh air line can be connected to the combustion air feed 4, which communicates with the outside air.

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.Via air slots 5, which are arranged in the combustion air supply 4 adjacent area in the housing 1, convection air is fed into the housing 1. As well as the combustion air supply 4, an exhaust gas guide 3 is in operative connection with the combustion chamber 6, wherein the exhaust gas guide 3 in any case, for example connected to a chimney, is in communication with the outside air.

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, as a detail in the Fig. 5 is shown.

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.Via a pump 10, the liquid fuel to the burner 7 can be guided. By means of a fan 9 are fuel vapors which have accumulated in the supply line to the burner 7, to be removed from ignition, the fan 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 combustion bowl 11 is formed, which is divided into two superimposed zones by a burner grate 12 and that in a lower early primary combustion zone 14 and an upper late primary combustion zone 16, wherein the later primary combustion zone 16, an igniter 13 is associated.

Unterhalb der frühen Primärbrennzone 14 ist eine Vorwärm-/Vergasungszone 15 angeordnet.
