Description

Haushaltungsherde der üblichen -Bauart sind in der Regel in ihrem inneren Aufbau so ausgeführt, daß die Heizgase von der Feuerung aus zunächst über den Bratofen hin, dann an der der Feuerung entgegengesetzten Seite nach unten und unter dem Bratofen entlang zu dem Abzugsschacht geführt werden. Hierbei kühlen sich die Heizgase auf dem langen Wege stark ab, so daß der Bratofen wohl eine starke Oberhitze, aber nur eine schwache Unterhitze erhält. Um die Heizgase bei Betrieb des Bratofens auf kürzestem Wege unter den Bratofen zu bringen und damit eine stärkere Unterhitze zu erreichen, hat man bereits vorgeschlagen, die Heizgase durch einen Sturzzug unmittelbar von der Feuerung unter den Bratofen zu leiten. Bei dieser Ausführungsart tritt jedoch infolge der mehrfachen scharfen Umlenkung der Heizgase ein erheblicher Zugverlust ein, so daß bei schwach ziehenden Schornsteinen ein einwandfreies Arbeiten des Herdes in Frage gestellt ist.Household cookers of the usual design are usually like this in terms of their internal structure executed that the heating gases from the furnace initially through the roasting oven, then on the opposite side of the furnace down and under the roasting oven be guided along to the discharge shaft. The heating gases cool down here the long way, so that the roasting oven has a strong top heat, but only receives a weak bottom heat. To reduce the heating gases when the roasting oven is in operation To bring ways under the roasting oven and thus to achieve a stronger bottom heat, it has already been proposed to direct the heating gases directly from the furnace under the roasting oven by means of a lintel. In this embodiment, however, occurs as a result of the multiple sharp deflection the heating gases a considerable loss of draft, so that with weakly drafting chimneys proper functioning of the stove is in question.

Nach der Erfindung sollen diese Nachteile bei kohlebeheizten Haushaltungsherden dadurch beseitigt werden, daß bei reinem Kochbetrieb die Heizgase in bekannter Weise über den Bratofen hin und am Wasserschiff vorbei in den Abzug geleitet werden, während sie bei Betrieb des Bratofens durch einen hinter der Feuerung angebrachten, in Richtung der Heizgase sich allmählich und stetig verengenden und mit gut ausgerundeten Umlenkungsecken versehenen Sturzschacht unter den Bratofen geführt werden. Durch diesen Sturzschiacht wird der Zugverbrauch so weit herabgemindert, daß der Herd auch an schwach ziehenden Schornsteinen einwandfrei arbeitet. Außerdem wird infolge der stärkeren Unterhitze eine erhebliche Brennstoffersparnis bei Betrieb des Bratofens erzielt.According to the invention, these disadvantages in coal-fired household stoves are intended be eliminated that in pure cooking mode, the heating gases in a known manner the roasting oven and past the watercraft into the fume cupboard while they When the roasting oven is in operation, one is installed behind the furnace, in the direction of the Heating gases gradually and steadily narrowing and with well-rounded deflection corners provided lintel shaft under the roasting oven. Through this fall chute the draft consumption is reduced so far that the stove is also weak pulling chimneys work properly. Also, as a result of the stronger Lower heating achieves considerable fuel savings when operating the roasting oven.

Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt, und zwar zeigtIn the drawing, the invention is shown in one embodiment, and although shows

Bei direktem Zug ziehen die Heizgase von der Feuerung α aus über den Bratofen d durch die geöffnete Klappe b am Wasserschiff vorbei in den Abzug. Bei Betrieb des Bratofens d wird die Klappe b geschlossen. Die Heizgase ziehen dann von der Feuerung a aus durch den Sturzschacht c in den Raum e unter, dem Brat of en, werden dort mehrmals durch Leitwände/ umgelenkt und gelangen von dort an dem Wasserschiff vorbei in den Abzug. Durch diese Zuganordnung werden die Heizgase auf dem kürzesten Wege unter den Bratofen geführt, wodurch eine kräftige Bratofenunterhitze erreicht wird.In the case of a direct draft, the heating gases pull from the furnace α via the roasting oven d through the open flap b past the watercraft and into the fume cupboard. When the roasting oven d is in operation, flap b is closed. The heating gases then move from the furnace a through the lintel shaft c into the room e under the roasting oven, are deflected there several times by baffles / and from there pass the watercraft into the fume cupboard. With this pull arrangement, the heating gases are guided under the roasting oven by the shortest route, which results in a strong roasting oven bottom heat.

Um den durch die mehrfache scharfe Umlenkung der Heizgase bedingten hohen Zugverbrauch des Herdes nach Möglichkeit zu verkleinern, weist gemäß der Erfindung der Sturzschacht c einen sich allmählich und stetig gegen den kleinsten Querschnitt e der Züge· unter dem Bratofen d in Richtung der strömenden Heizgase verengenden, düsenartig ausgebildeten Querschnitt auf. Dadurch erhalten die Heizgase eine gleichförmige Beschleunigung auf ihre größte Geschwindigkeit, die im engsten Zug e unter dem Bratofen erreicht wird. Der an sich unvermeidliche Zugverlust wird dadurch wesentlich herabgesetzt, so daß der Herd auch an schwach ziehenden oder niedrigen Schornsteinen einwandfrei arbeitet.In order to reduce the high draft consumption of the stove, which is caused by the multiple sharp deflections of the hot gases, as far as possible, according to the invention the lintel shaft c has a gradually and steadily narrowing towards the smallest cross section e of the drafts under the roasting oven d in the direction of the flowing hot gases, nozzle-like cross-section. This gives the heating gases a uniform acceleration to their greatest speed, which is reached in the closest train e under the roasting oven. The inherently unavoidable loss of draft is significantly reduced so that the stove works perfectly even on low draft or low chimneys.
