- the room air is thus supplied with sufficiently heated fresh air, so that the oxygen content of the room air is relatively high and takes place by the combustion process taking place in the stove oxygen deprivation to no oxygen deficiency in the indoor air.
- the obturator 16a of the line 16 can then be opened, so that combined fresh air and room air are sucked in and heated.
- the accumulated in the floor near, still relatively cool air flows through the intake manifold 16b and is heated together with fresh air in the annular channel 10 and passes as heated air in the ceiling area of the room. If old shut-off elements 13b, 16a and 17a are completely or at least partially open, then a relatively stable flow level arises in the room.
- the obturator 17a for the supply of fresh air can be closed, but it should be noted that the room should be supplied with fresh air in other ways.
- the proposed additional device works automatically without external energy and ensures a pleasant indoor climate. It can be cheaply manufactured and assembled. If necessary, the opening and closing movements of the shut-off can be done by means of electric actuators, which are integrated into an automatic control system, via which also room temperature and / or oxygen content in the room can be monitored and controlled.

Abstract
Description
Die Erfindung bezieht sich auf eine Zusatzeinrichtung für Kaminöfen, die mit festen Brennstoffen beheizt und ohne externe Frischluftzufuhr betrieben werden.The invention relates to an additional device for stoves, which are heated with solid fuels and operated without external fresh air.
Kaminöfen unterschiedlicher Bauart sind bereits seit langem bekannt. Sogenannte normale Kaminöfen beziehen die zur Verbrennung erforderliche Verbrennungsluft im allgemeinen aus der Raumluft. Während des Verbrennungsvorganges entsteht in unmittelbarer Nähe der Helzquelle eine hohe Strahlungswärme. Aufgrund der aufsteigenden Wärme bildet sich unter der Decke des beheizten Raumes ein Wärmestau. Im Fußbodenbereich bleibt über einen längeren Zeitraum eine kalte Luftschicht erhalten, die sich nur langsam erwärmt. In der Nähe von Fenstern und Türen kann es zu Zuglufterscheinungen kommen. Durch den Verbrennungsvorgang wird der Raumluft Sauerstoff entzogen, sodass ein regelmäßiges Nachlüften erforderlich ist, wodurch wieder Kaltluft in den Raum gelangt und Zuglufterscheinungen auftreten. Dadurch bedingt stellt sich ein ungünstiges Raumklima ein. Eintretender Sauerstoffmangel der Raumluft führt zu Ermüdungserscheinungen und wirkt sich nachteilig auf den Brennvorgang aus.Stoves of different design have long been known. So-called normal wood-burning stoves generally draw the combustion air required for combustion from the room air. During the combustion process, a high radiant heat is generated in the immediate vicinity of the Helz source. Due to the rising heat, heat builds up under the ceiling of the heated room. In the floor area, a cold air layer remains over a longer period, which heats up only slowly. Drowsiness may occur near windows and doors. Due to the combustion process oxygen is extracted from the room air, so that a regular after-ventilation is necessary, whereby cold air enters the room again and draft phenomena occur. As a result, an unfavorable room climate sets in. Entering oxygen deficiency of the room air leads to signs of fatigue and has an adverse effect on the burning process.
Bei Kaminöfen, die mit externer Frischluftzufuhr betrieben werden, gelangt die Frischluft unmittelbar in den Verbrennungsraum des Kaminofens. Im Raum entsteht nur eine geringe Luftbewegung. Im Deckenbereich bildet sich ein Wärmestau und in Fußbodennähe eine relativ kalte Luftschicht.In the case of wood-burning stoves operated with an external supply of fresh air, the fresh air passes directly into the combustion chamber of the stove. There is only a slight air movement in the room. In the ceiling area forms a heat accumulation and near the floor a relatively cold layer of air.
Aus der Praxis ist ein Kaminofen mit einer zylindrischen Brennkammer bekannt der als Warmluftofen ausgebildet ist. Die Brennkammer ist aus gebogenen Stahlrohren gebildet, deren Rohroberfläche teilweise Innerhalb der Brennkammer Ilegt. Über die Rohre wird kalte Luft angesaugt, die von untern nach oben strömend, erwärmt wird und am oberen Ende der Rohre als Warmluft abströmt. Durch den andauernden Umwälzvorgang soll eine schnelle und gleichmäßige Erwärmung der Raumluft erzielt werden.From practice, a stove with a cylindrical combustion chamber is known which is designed as a hot air oven. The combustion chamber is formed from bent steel tubes, the tube surface partially within the combustion chamber lays. Cold air is sucked in through the pipes, which flows from the bottom to the top, is heated and flows off at the upper end of the pipes as warm air. Due to the continuous circulation process, a rapid and uniform heating of the room air should be achieved.
Der Nachteil dieses Kaminofens besteht darin, dass der Luftumwälzvorgang Im unmittelbaren Aufstellbereich des Ofens stattfindet. Es muss eine ständige Frischluftzufuhr gewährleistet sein, um den Sauerstoffentzug der Raumluft auszugleichen. Die erzeugte Warmluft wird nur ungleichmäßig im Raum verteilt, sodass es insbesondere In der Nähe von Türen und Fenstern zu Zuglufterscheinungen kommt.The disadvantage of this stove is that the Luftumwälzvorgang takes place in the immediate installation area of the furnace. It must be ensured a constant supply of fresh air to compensate for the oxygen deprivation of the room air. The generated hot air is only distributed unevenly in the room, so that it comes especially in the vicinity of doors and windows to draft phenomena.
Bekannt sind auch verschiedene Lösungen, Kaminöfen mit einem Wärmetauscher auszurüsten, insbesondere um die über den Schornstein abgeführten Rauchgase zur zusätzlichen Wärmerückgewinnung zu nutzen.Also known are various solutions to equip stoves with a heat exchanger, in particular to use the discharged via the chimney flue gases for additional heat recovery.
Bekannt ist ein Wärmetauscher für einen Kaminofen (
Ein zusätzlicher Wärmetauscher trägt zwar zu einer Erhöhung der Raumlufttemperatur bei, beseitigt aber nicht die vorgenannten Mängel hinsichtlich der Luftvertellung und des Raumklimas.Although an additional heat exchanger contributes to an increase in the room air temperature, but does not eliminate the aforementioned deficiencies in terms of Luftvertellung and the indoor environment.
Der Erfindung liegt die Aufgabe zugrunde, eine Zusatzeinrichtung für Kaminöfen zu schaffen, die zu einer wesentlichen Verbesserung des Raumklimas führt, eine gute und gleichmäßige Raumluftumwälzung ermöglicht, eine ausreichende Menge an Verbrennungsluft liefert und mit geringem Kostenaufwand installiert werden kann.The invention has for its object to provide an additional device for stoves, which leads to a significant improvement in indoor climate, allows a good and uniform room air circulation, provides a sufficient amount of combustion air and can be installed at low cost.
Erfindungsgemäß wird die Aufgabe durch die im Anspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen sind Gegenstand der Ansprüche 2 bis 8.According to the invention the object is achieved by the features specified in claim 1. Advantageous embodiments and further developments are subject matter of
Das Rauchgasabführungsrohr des Kaminofens ist von einem Luft führenden Mantelrohr mit zwei um mindesten 90° versetzt angeordneten Anschlussstutzen umgeben. Der eine Anschlussstutzen steht mit einem ersten Kanal zur Zuführung von Frischluft in Verbindung, In den ein Absperrorgan eingebunden ist. In Strömungsrichtung der Frischluft ist hinter dem Absperrorgan, in den ersten Kanal ein dritter Kanal zur Ansaugung von Raumluft eingebunden, der mit einem Absperrorgan ausgerüstet ist. Der andere Anschlussstutzen ist mit einem nach oben gerichteten zweiten Kanal zur Abgabe von erwärmter Luft verbunden, der mit einem Absperrorgan ausgerüstet ist.The flue gas outlet pipe of the stove is surrounded by an air-conducting jacket pipe with two offset by at least 90 ° arranged connecting pieces. The one connecting piece communicates with a first channel for supplying fresh air, in which a shut-off element is integrated. In the flow direction of the fresh air behind the obturator, in the first channel, a third channel for the intake of room air is involved, which is equipped with a shut-off. The other spigot is connected to an upwardly directed second duct for the delivery of heated air, which is equipped with a shut-off device.
Der dritte Kanal zur Ansaugung von Raumluft ist vorzugsweise mit Abzweigkanälen verbunden, die an verschiedenen Stellen des Raumes, im Bereich der den Raum begrenzenden Wände, In Bodennähe, enden.The third channel for intake of room air is preferably connected to branch channels, which terminate at different points of the room, in the area of the wall bounding the room, near the floor.
Der zweite, Warmluft führende Kanal ist bis in den Bereich der Raumdecke geführt.The second, hot air leading channel is led to the area of the ceiling.
Dieser kann auch mit Verzweigungskanälen verbunden sein, deren Austrittsöffnungen in Raumdeckenhöhe verteilt angeordnet sind.This can also be connected to branch channels whose outlet openings are arranged distributed in ceiling height.
Während der Anhelzphase des Kaminofens ist der zweite Kanal mittels eines Absperrorgans geschlossen und die Kanäle für die Zuführung von Raumluft und Frischluft sind geöffnet. Nach Beendigung der Aufheizphase nimmt das Absperrorgan im zweiten Kanal eine geöffnete Stellung ein, wobei die Raumluftzufuhr unterbrochen und der Kanal für die Frischluftzufuhr geöffnet Ist.During the Anhelzphase of the stove, the second channel is closed by means of a shut-off and the channels for the supply of room air and fresh air are open. After completion of the heating phase, the obturator in the second channel assumes an open position, the room air supply is interrupted and the channel for the fresh air supply is open.
Während des weiteren Heizvorganges sind die Kanäle für die Zuführung von Frischluft und Raumluft geöffnet oder wahlweise zuschaltbar.During the further heating process, the channels for the supply of fresh air and room air are open or optionally switchable.
Die Zusatzeinrichtung kann mit einer automatischen Regeleinrichtung gekoppelt werden, die ausgehend von gemessenen Werten für den Sauerstoffgehalt in der Raumluft, der Rauchgastemperatur und der Raumlufttemperatur das Öffnen und Schließen der Absperrorgane mittels Stellantrieben steuert.The auxiliary device can be coupled to an automatic control device, which controls the opening and closing of the shut-off devices by means of actuators based on measured values for the oxygen content in the room air, the flue gas temperature and the room air temperature.

Sie versorgt den Raum und die Heizquelle mit der benötigten Verbrennungsluft durch selbständiges Ansaugen von Frischluft. Im beheizten Raum wird ein angenehmes Raumklima geschaffen, da dieser ausreichend mit Frischluft versorgt wird. Im Raum ist aufgrund der herrschenden Thermik eine gute Durchmischung der Raumluft gewährleistet.The proposed accessory requires no additional electrical energy, is maintenance-free and easy to operate. It supplies the room and the heating source with the required combustion air through the independent intake of fresh air.

In dem Raum 1 ist auf dem Fußboden 2 ein mit festen Brennstoffen beheizbarer Kaminofen 7 aufgestellt (
Das Mantelrohr 9 besitzt zwei Anschlussstutzen 11 und 12, die um 180° versetzt angeordnet sind. Der nach oben zeigende Anschlussstutzen 11 ist mit einem Steigrohr 13 (zweiter Kanal) verbunden. Das Steigrohr 13 ragt bis in den Deckenbereich und besitzt an seinem oberen Ende eine Luftaustrittsöffnung 13a, über die erwärmte Warmluft abströmt. In das Steigrohr 13 ist ein Absperrorgan 13b eingebunden, um während des Aufheizvorganges des Kaminofens 7 den Austritt von noch nicht ausreichend erwärmter Luft zu unterbinden.The
Da Stelgrohr 13 kann zusätzlich auch mit einer Luftverteilungsleitung 14 verbunden sein, die im Bereich der Raumdecke 5 umlaufend, entlang der Seitenwände 3, 4 geführt ist und abschnittsweise Luftaustrittsöffnungen 14a besitzt.Since Stelgrohr 13 may additionally be connected to an
An den anderen, nach unten zeigenden Stutzen 12 des Mantelrohres 9 Ist ein Rohr oder Kanal 15 angeschlossen, der mit einer Leitung 16 (dritter Kanal) zur Zuführung bzw. Ansaugung von Raumluft und einer Leitung 17 (erster Kanal) zur Zuführung von Frischluft verbunden ist. In die beiden Leitungen 16 und 17 ist jeweils ein Absperrorgan 16a und 17a angeordnet, sodass dem Rohr oder Kanal 15 wahlweise Frischluft oder Raumluft zugeführt werden können.At the other, downwardly pointing
Die beiden Leitungen 16 und 17 sind vorzugsweise unterhalb des Fußbodens 2 verlegt. Die Leitung 16 zur Zuführung von Raumluft ist entlang der Seitenwände 3, 4 geführt und besitzt mehrere senkrecht angeordnete Ansaugstutzen 16b, die In Seitenwandnähe durch den Fußboden 2 geführt sind und unmittelbar oberhalb des Fußbodens 2 enden.The two
Die Leitung 17 zur Zuführung von Frischluft ist über eine Öffnung in einer der Außenwände des Gebäudes mit der Außenluft verbunden.The conduit 17 for supplying fresh air is connected via an opening in one of the outer walls of the building with the outside air.
Die Funktionsweise der Zusatzeinrichtung ist folgende:The operation of the attachment is the following:
Während der Anhelzphase des Kaminofens 7 wird das Absperrorgan 13b des Steigrohres 13 geschlossen. Die Absperrorgane 16a und 17a der Leitungen 16 und 17 für die Zuführung von Raumluft und Frischluft bleiben geöffnet. Aufgrund der durch das Rohr 8 in den Schornstein 6 abgeführten heißen Rauchgase wird die im Ringkanal 10 und Steigrohr 13 befindliche Luft erwärmt. Nach Beendigung der Anhelzphase, das in den Schornstein abgeführte Rauchgas hat eine Betriebstemperatur von ca. 200 bis 300°C erreicht, wird das Absperrorgan 13a geöffnet und das Absperrorgan 16 zur Zuführung von Raumluft geschlossen. Die im Steigrohr erwärmte Luft strömt in Deckennähe ab und Frischluft wird über die Leitung 17 angesaugt, die während des Umströmens des heißen Rauchgasabführungsrohres 8 im Ringkanal 10 auf eine Temperatur bis ca. 40 °C erwärmt wird. Diese warme Luft strömt Im Deckenbereich über das Steigrohr 13 oder die Luftaustrittsöffnungen 14a der Luftverteilungsieltung 14 in Deckenhöhe ab. Durch den natürlichen Strömungsvorgang wird die Bildung eines Wärmestaus im Deckenbereich verhindert. Die warme Frischluft strömt entlang der Seitenwände 3, 4 des Raumes und sorgt für eine gleichmäßige Raumluftumwälzung. Der Raumluft wird somit ausreichend erwärmte Frischluft zugeführt, sodass der Sauerstoffgehalt der Raumluft vergleichsweise hoch ist und der durch den Verbrennungsvorgang im Kaminofen stattfindende Sauerstoffentzug zu keinem Sauerstoffmangel in der Raumluft führt. Nach einer bestimmten Heizdauer kann dann das Absperrorgan 16a der Leitung 16 geöffnet werden, sodass kombiniert Frisch- und Raumluft angesaugt und erwärmt werden. Die sich in Fußbodennähe angesammelte, noch relativ kühle Luft strömt über die Ansaugstutzen 16b ab und wird zusammen mit Frischluft im Ringkanal 10 erwärmt und gelangt als erwärmte Luft in den Deckenbereich des Raumes. Sind alte Absperrorgane 13b, 16a und 17a vollständig oder zumindest teilweise geöffnet, so stellt sich im Raum ein relativ stabiles Strömungsniveau ein. Zeitweise kann das Absperrorgan 17a für die Frischluftzufuhr auch geschlossen werden, wobei jedoch zu beachten ist, dass dem Raum auf anderem Wege ausreichend Frischluft zugeführt werden sollte.During the Anhelzphase of the
Die vorgeschlagene Zusatzeinrichtung arbeitet selbsttätig ohne Fremdenergie und sorgt für ein angenehmes Raumklima. Sie kann kostengünstig hergesteilt und montiert werden. Erforderlichenfalls können die Öffnungs- und Schließbewegungen der Absperrorgane mittels elektrischer Stellmotoren erfolgen, wobei diese in ein automatisches Regelsystem eingebunden sind, über das auch Raumtemperatur und/oder Sauerstoffgehalt im Raum überwacht und geregelt werden können.The proposed additional device works automatically without external energy and ensures a pleasant indoor climate. It can be cheaply manufactured and assembled. If necessary, the opening and closing movements of the shut-off can be done by means of electric actuators, which are integrated into an automatic control system, via which also room temperature and / or oxygen content in the room can be monitored and controlled.
