Description
Die Erfindung betrifft eine Heizeinrichtung umfassend eine Luftleitvorrichtung, sowie ein Gehäuse mit einer bedarfsweise öffenbaren Brennraumtür in einer Seitenwand des Gehäuses, einen im Inneren des Gehäuses angeordneten und über die Brennraumtür zugänglichen Brennraum und zumindest eine Auslassöffnung im Brennraum, über die ein Luftzuleitungskanal, insbesondere für Sekundärluft, derart mit dem Brennraum verbunden ist, dass eine zugeführte Luft an einer Innenseite einer transparenten Sichtscheibe in der Brennraumtür entlangströmt. Die
Insbesondere bei modernen Heizeinrichtungen, welche in den zu beheizenden Wohn- bzw. Arbeitsräumen aufgestellt sind, welche vorzugsweise mit Holz, insbesondere mit Pellets, Hackschnitzel und/oder Scheitholz betrieben werden können und welche Heizeinrichtungen relativ große, transparente Sichtscheiben vorzugsweise in der Brennraumtür der Heizeinrichtung aufweisen, ist es bekannt, dass zur Verhinderung von Rußablagerungen auf der Innenseite der Sichtscheibe diese Innenseite während des Verbrennungsvorgangs mit einem Luftvorhang aus Frischluft, welche Frischluft auch als Spülluft bezeichnet wird, geschützt wird, sodass die Rußpartikel bzw. Verbrennungsrückstände die Innenseite der Sichtscheibe nicht erreichen bzw. sich dort ablagern können. Zu diesem Zweck ist die zumindest eine Auslassöffnung für die Spülluft, welche Spülluft typischerweise in weiterer Folge auch als Sekundärluft für die Aufrechterhaltung des Verbrennungsvorgangs in der Heizeinrichtung Verwendung findet, derart im Bereich der Innenseite der Sichtscheibe angeordnet, dass die aus der zumindest einen Auslassöffhung austretende Spülluft an der Innenseite der Sichtscheibe entlang strömt und den schützenden Luftvorhang bildet. Jedoch kommt es bei den bekannten Spülluftsystemen insbesondere aufgrund eines ungleichmäßigen Austritts der Spülluft aus der zumindest einen Auslassöffnung im Brennraum in manchen Fällen immer noch zu einer Ablagerung von Verbrennungsrückständen bzw. zu einer Schlierenbildung auf der Innenseite der Sichtscheibe, sodass die Sichtscheibe vor allem nach einer längeren Betriebsdauer blind wird. Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, die Zufuhr von Spülluft an die Innenseite der Sichtscheibe der Heizeinrichtung zu verbessern, sodass eine Ablagerung von Verbrennungsrückständen an der Innenseite der Sichtscheibe, insbesondere auch nach einer längeren Betriebsdauer, praktisch ausgeschlossen ist.In particular, in modern heating devices, which are placed in the residential or working spaces to be heated, which preferably with wood, especially with pellets, wood chips and / or firewood can be operated and which heaters have relatively large, transparent windows preferably in the combustion chamber door of the heater , It is known that to prevent soot deposits on the inside of the visor this inside during the combustion process with an air curtain from fresh air, which fresh air is also referred to as scavenging air, is protected, so that the soot particles or combustion residues do not reach the inside of the lens or can be deposited there. For this purpose, the at least one outlet opening for the scavenging air, which scavenging air is typically subsequently also used as secondary air for maintaining the combustion process in the heating device, arranged in the region of the inside of the visor, that the purging air exiting from the at least one Auslassöffhung flows along the inside of the lens and forms the protective air curtain. However, in the case of the known scavenging air systems, in particular due to an uneven discharge of the scavenging air from the at least one outlet opening in the combustion chamber, deposits of combustion residues or streaks on the inside of the viewing window still persist in some cases, so that the viewing window is primarily after a longer period Operating time becomes blind. The present invention is therefore based on the object to improve the supply of scavenging air to the inside of the lens of the heater, so that a deposition of combustion residues on the inside of the lens, especially after a longer period of operation, is practically impossible.
Die Aufgabe der Erfindung wird mit einer Luftleitvorrichtung für eine Heizeinrichtung der eingangs genannten Art gelöst, welche Luftleitvorrichtung aus einem luftundurchlässigen Material, insbesondere Metall, gebildet ist und welche Luftleitvorrichtung anschließend an die zumindest eine Auslassöffnung im Brennraum angeordnet ist und die zugeführte Luft bzw. Spülluft an einer ebenen Vorderseite der Luftleitvorrichtung entlang strömt, welche Vorderseite Vorsprünge, insbesondere Noppen, aufweist.The object of the invention is achieved with an air guiding device for a heating device of the type mentioned above, which air guiding device is formed from an air-impermeable material, in particular metal, and which air guiding device is arranged next to the at least one outlet opening in the combustion chamber and the supplied air or scavenging air a planar front side of the air guiding device flows along, which has front side projections, in particular knobs.
Auf diese Weise wird eine gleichmäßige Verteilung bzw. Vergleichmäßigung der zugeführten Spülluft erreicht, sodass der durch die Spülluft gebildete Luftvorhang die Innenseite der Sichtscheibe möglichst vollflächig vor einer Verschmutzung durch Verbrennungsrückstände bzw. Rußablagerungen schützt. Die Vorsprünge an der Vorderseite der Luftleitvorrichtung werden dabei von der zugeführten Spülluft umströmt bzw. die Spülluft tritt in den Zwischenräumen zwischen den Vorsprüngen hindurch, bei welchem Vorgang die Spülluft homogenisiert und gleichmäßig über die gesamte Ausdehnung der Luftleitvorrichtung verteilt wird, sodass die Spülluft nach dem Passieren der Luftleitvorrichtung gleichmäßig über die gesamte Breite der Luftleitvorrichtung verteilt aus dieser austritt. Darüber hinaus kann eine solche Luftleitvorrichtung konstruktiv auf besonders einfache Art und Weise hergestellt und in der Heizeinrichtung integriert werden.In this way, a uniform distribution or homogenization of the supplied scavenging air is achieved, so that the air curtain formed by the scavenging air protects the inside of the window as completely as possible against contamination by combustion residues or soot deposits. The projections on the front side of the air guiding device are thereby flowed around by the supplied scavenging air or the scavenging air passes in the spaces between the protrusions, in which process the scavenging air is homogenized and distributed uniformly over the entire extent of the spoiler, so that the scavenging air after passing the air deflector evenly distributed over the entire width of the spoiler from this exits. In addition, such a spoiler can be constructively manufactured in a particularly simple manner and integrated in the heater.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindungen ergeben sich aus den Unteransprüchen sowie aus der Beschreibung in Zusammenschau mit den Figuren.Advantageous embodiments and further developments of the invention will become apparent from the dependent claims and from the description in conjunction with the figures.
Günstig ist es, wenn die zumindest eine Auslassöffnung in einem oberen Bereich des Brennraums angeordnet ist und wenn bei geschlossener Brennraumtür die vorzugsweise senkrecht orientierte Vorderseite der Luftleitvorrichtung gegenüber einer Innenseite der Brennraumtür über der Sichtscheibe angeordnet ist. Bei einer solchen vorteilhaften Anordnung der zumindest einen Auslassöffnung sinkt die zugeführte Spülluft grundsätzlich von selbst aus dem oberen Bereich des Brennraums in einen unteren Bereich des Brennraums, da die zugeführte Spülluft kälter und damit schwerer ist als die im Brennraum bereits vorhandene, aufgeheizte Luft. Bei diesem gewissermaßen natürlichen Absinkvorgang der zugeführten Spülluft strömt diese dabei entlang der Innenseite der Sichtscheibe und spült diese bzw. schützt diese durch Bildung eines Luftvorhangs vor der Ablagerung von Verbrennungsrückständen bzw. Rußpartikeln. Weiters ist die mit den Vorsprüngen versehene Vorderseite der Luftleitvorrichtung aufgrund der Anordnung der Luftleitvorrichtung gegenüber einer Innenseite der Brennraumtür über der Sichtscheibe und nicht etwa gegenüber einer Innenseite der Sichtscheibe von außen durch die Sichtscheibe hindurch nicht sichtbar und die Luftleitvorrichtung deckt somit auch keinen Teil der Sichtscheibe ab.It is expedient if the at least one outlet opening is arranged in an upper region of the combustion chamber and if, with the combustion chamber door closed, the preferably vertically oriented front side of the air guiding device is arranged opposite the inner side of the combustion chamber door above the viewing window. With such an advantageous arrangement of the at least one outlet opening, the supplied scavenging air basically drops by itself from the upper region of the combustion chamber into a lower region of the combustion chamber, since the scavenging air supplied is colder and thus heavier than the heated air already present in the combustion chamber. In this quasi natural Absinkvorgang the supplied scavenging air flows while doing along the inside of the lens and flushes them or protects them by forming an air curtain from the deposition of combustion residues or soot particles. Furthermore, the provided with the projections front of the spoiler due to the arrangement of the spoiler relative to an inside of the combustion chamber door over the visor and not about an inside of the visor from the outside through the lens is not visible and the spoiler thus covers no part of the lens ,
Günstig ist es auch, wenn ein Abstand zwischen Spitzen- bzw. Endbereichen der Vorsprünge und der Innenseite der Brennraumtür weniger als 1,5 cm, insbesondere weniger als 1 cm, bevorzugt ungefähr 0,5 cm beträgt. Auf diese Weise ist einerseits eine ausreichende Vergleichmäßigung des Luftstroms sichergestellt und andererseits ist aufgrund des verbleibenden Durchflussquerschnitts für die zugeführt Luft eine ausreichende Versorgung der Heizeinrichtung mit Spülluft bzw. Sekundärluft sichergestellt.It is also favorable if a distance between the tip or end regions of the projections and the inside of the combustion chamber door is less than 1.5 cm, in particular less than 1 cm, preferably approximately 0.5 cm. In this way, on the one hand a sufficient equalization of the air flow is ensured and on the other hand, due to the remaining flow cross-section for the supplied air sufficient supply of the heater with purging air or secondary air ensured.
Günstig ist es weiterhin, wenn die Luftleitvorrichtung am starren Teil des Gehäuses, in welchem Teil der Brennraum untergebracht ist, fixiert ist und von der geschlossenen Brennraumtür abgedeckt bzw. überdeckt wird. Auf diese Weise wird eine Erhöhung des Gewichts der Brennraumtür vermieden, welche eintreten würde, wenn die Luftleitvorrichtung an der Brennraumtür fixiert wäre. Somit wird eine erschwerte Handhabbarkeit bzw. Bedienbarkeit der Brennraumtür aufgrund des erhöhten Gewichts vermieden. Durch die Abdeckung bzw. Überdeckung, insbesondere der Vorderseite der Luftleitvorrichtung mit den Vorsprüngen, durch die bei Bedarf wegbewegbare Brennraumtür wird eine einfache und schnelle Zugreifbarkeit und damit eine einfache und schnelle Reinigung der Luftleitvorrichtung ermöglicht.It is also favorable when the air guiding device is fixed to the rigid part of the housing, in which part of the combustion chamber is housed, and is covered or covered by the closed combustion chamber door. In this way, an increase in the weight of the combustion chamber door is avoided, which would occur if the spoiler was fixed to the combustion chamber door. Thus, a difficult handling or operability of the combustion chamber door is avoided due to the increased weight. By covering or covering, in particular the front of the spoiler with the projections, by the wegbewegbare on demand combustion chamber door is a simple and quick accessibility and thus a simple and quick cleaning of the spoiler allows.
Günstig ist es zudem, wenn sich die Luftleitvorrichtung zumindest über eine gesamte Breite der Sichtscheibe der Brennraumtür erstreckt. Auf diese Weise ist eine umfassende bzw. vollständige Spülung der Innenseite der Sichtscheibe und damit ein vollständiger Schutz der Innenseite der Sichtscheibe vor Ablagerungen von Verbrennungsrückständen sichergestellt.It is also favorable if the air guiding device extends at least over an entire width of the viewing window of the combustion chamber door. In this way, a comprehensive or complete flushing of the inside of the lens and thus a complete protection of the inside of the lens is ensured against deposits of combustion residues.
Vorteilhaft ist es, wenn sich die Luftleitvorrichtung zumindest über eine gesamte Breite des Brennraums erstreckt. Damit ist neben der Bildung eines Luftvorhangs vor der Innenseite der Sichtscheibe auch eine gleichmäßige und umfassende Zufuhr von Sekundärluft in den Brennraum bzw. zum Brandherd sichergestellt.It is advantageous if the air guiding device extends at least over an entire width of the combustion chamber. Thus, in addition to the formation of an air curtain in front of the inside of the lens and a uniform and comprehensive supply of secondary air is ensured in the combustion chamber or the source of fire.
Vorteilhaft ist es auch, wenn die Vorsprünge auf der Vorderseite der Luftleitvorrichtung eine Höhe von ungefähr 0,5 cm aufweisen. Auf diese Weise ist sowohl eine ausreichende Vergleichmäßigung des zugeführten Spülluftstroms als auch ein ausreichend großer Durchgangsquerschnitt zur Zufuhr von genügend Spülluft bzw. Sekundärluft in den Brennraum sichergestellt.It is also advantageous if the projections on the front side of the air guiding device have a height of approximately 0.5 cm. In this way, both a sufficient equalization of the supplied scavenging air flow and a sufficiently large passage cross-section for the supply of sufficient scavenging air or secondary air is ensured in the combustion chamber.
Besonders vorteilhaft ist es, wenn die Vorsprünge an der Vorderseite der Luftleitvorrichtung in zumindest drei horizontalen Reihen angeordnet sind, wobei die Vorsprünge in zwei übereinander liegenden Reihen zueinander versetzt angeordnet sind. Mit der versetzten Anordnung der Vorsprünge in übereinander liegenden Reihen ist insbesondere die Anordnung eines darüber- bzw. darunterliegenden Vorsprungs genau über bzw. unter dem Zwischenraum zwischen zwei Vorsprüngen in der darunter bzw. darüber liegenden Reihe gemeint. Auf diese Weise ist eine besonders gute Vergleichmäßigung bzw. Vermischung der unterschiedlichen Strömungen in der zugeführten Spülluft sichergestellt.It when the projections are arranged at the front of the spoiler in at least three horizontal rows, wherein the projections are arranged offset in two superimposed rows to each other is particularly advantageous. The staggered arrangement of the projections in superimposed rows means, in particular, the arrangement of an overlying or underlying protrusion just above or below the space between two protrusions in the row below or above. In this way, a particularly good homogenization or mixing of the different flows in the supplied purging air is ensured.
Vorteilhaft ist es, wenn die Vorderseite der Luftleitvorrichtung eine Höhe von ungefähr 7 cm aufweist. Auf diese Weise ist einerseits ausreichend Platz zur Anordnung der Vorsprünge vorhanden und damit eine ausreichende Vergleichmäßigung der zugeführten Spülluft bzw. Sekundärluft sichergestellt und andererseits wird dadurch kein zu großer Widerstand gegenüber dem Durchfluss der Spül- bzw. Sekundärluft erzeugt.It is advantageous if the front of the spoiler has a height of about 7 cm. In this way, on the one hand sufficient space for the arrangement of the projections is present, thus ensuring a sufficient homogenization of the supplied scavenging air or secondary air and on the other hand, by no great resistance to the flow of rinsing or secondary air is generated.
Günstig ist es schließlich, wenn die Luftleitvorrichtung mit den Vorsprüngen aus einem einteiligen Gussteil gebildet ist. Auf diese Weise ist eine sehr kostengünstig herstellbare Luftleitvorrichtung geschaffen, welche darüber hinaus einen sehr stabilen Aufbau aufweist. Dies ist besonders im Zusammenhang mit einer Anordnung der Luftleitvorrichtung im Bereich der Brennraumtür der Heizeinrichtung von großem Vorteil, da durch die geöffnete Brennraumtür gegebenenfalls mehr oder weniger schwere Holzscheite in den Brennraum eingebracht werden, bei welchem Vorgang die Luftleitvorrichtung entsprechenden Kräften ausgesetzt sein kann. Durch die stabile Ausführung der Luftleitvorrichtung werden Beschädigungen derselben vermieden.Finally, it is favorable if the air guiding device is formed with the projections of a one-piece casting. In this way, a very cost-producible air deflector is created, which also has a very stable structure. This is particularly advantageous in connection with an arrangement of the air guiding device in the region of the combustion chamber door of the heating device, since possibly more or less heavy logs are introduced into the combustion chamber through the open combustion chamber door, in which process the air guiding device can be exposed to corresponding forces. Due to the stable design of the spoiler damage the same are avoided.
