Abstract

A gas burner for a domestic cooker is constructed from two co-axial cylindrical housings with an annular chamber (2) formed between the walls of the housings. The gas supply pipe is connected to the outer housing so that a mixture of gas and primary air flows into the annular chamber. The inner housing has a ring of holes (3) in its wall near the upper end. The mixture of gas and primary air flows through these holes into the circular duct (4) fomred by the inner housing. This mixture is ignited to form tongues of flame which are directed radially inwards. Secondary combustion air is drawn into the duct (4) and flows upwards to the flames. USE - Domestic gas cookers.

Description

Die Erfindung betrifft einen Gasbrenner mit vorgegebener, möglichst gleichmäßiger Wärmeflußverteilung an den Boden des Gefäßes, insbesondere für Haushaltsherde und Haushaltskocher.The invention relates to a gas burner with a predetermined, heat flow distribution to the bottom of the Vessel, especially for domestic stoves and cookers.

Bei möglichst großen Wirkungsgrad wird ein niedriges CO und N x O y -Gehalt im Abgas angestrebt, da der Gasbrenner in geschlossenen Räumen ohne Abgasabzug in Betrieb sein soll. Weiterhin darf der Gasbrenner bei seitlichen Windstößen nicht ausgehen. Auch bei einseitigem Anzünden muß gewährleistet sein, daß die Flamme sich in kürzester Zeit über die ganze Krone ausbreitet.With the highest possible efficiency, a low CO and N x O y content in the exhaust gas is aimed for, since the gas burner should be operated in closed rooms without exhaust gas extraction. Furthermore, the gas burner must not go out when there are gusts of wind from the side. Even with one-sided lighting, it must be ensured that the flame spreads over the entire crown in the shortest possible time.

Es ist bekannt, daß zur Erfüllung dieser Erfordernisse divergenter Gasbrenner verwendet ist.It is known to be more divergent to meet these needs Gas burner is used.

Es besteht die Möglichkeit, den Wirkungsgrad sowie den Widerstand gegen seitliche Windstöße bei den bisherigen Gasbrennern zu verbessern. Bei den bisherigen Gasbrennern ist die minimale Nennleistung begrenzt.There is a possibility of efficiency and resistance against lateral gusts of wind with previous gas burners improve. The minimum for previous gas burners Rated power limited.

Der Erfindung liegt die Aufgabe zugrunde, den Wirkungsgrad und den Widerstand gegen seitliche Windstöße zu erhöhen, sowie die untere Grenze der Nennleistung zu reduzieren.The invention has for its object the efficiency and to increase the resistance to lateral gusts of wind, as well as the reduce the lower limit of the nominal power.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Flammenzungen gegen die Symmetrieachse des Gasbrenners gerichtet sind.This object is achieved in that the Tongues of flame directed against the symmetry axis of the gas burner are.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Wärmeflußverteilung am Boden des Gefäßes gleichmäßig wird, dadurch erhöht sich der Wirkungsgrad. Da die Ausströmungslöcher auf der inneren Seite des Gasbrenners sind, wird die Flamme von seitlichen Windstößen geschützt.The advantages achieved with the invention are in particular that the heat flow distribution at the bottom of the vessel is even efficiency increases. Because the outflow holes are on the inside of the gas burner, the flame protected from side gusts of wind.

Der Umlauf der Flamme wird durch die Konvergenz der Flammenzungen auch bei niedrigeren Nennleistungen sichergestellt.The circulation of the flame is due to the convergence of the flame tongues ensured even with lower nominal outputs.

Ein Ausführungsbeispiel der Erfindung ist in der Abb. 1 dargestellt. Der abgebildete Gasbrenner ist aus Blechteilen zusammengeschweist, ist jedoch auch aus anderen Materialien und mit anderen Technologien (z. B. Gießverfahren) herstellbar. An embodiment of the invention is shown in Fig. 1. The gas burner shown is welded together from sheet metal parts, but can also be made from other materials and with other technologies (e.g. casting process).

Die 2. und 3. Abbildung zeigen verschiedene Formen von Gasbrennern, die für verschiedene Zwecke geeignet sind.The 2nd and 3rd figure show different forms of gas burners, that are suitable for different purposes.

Die Symmetrieachsen der Ausflußöffnungen (s. Abb. 1, 2 und 3) schließen ein 90° Winkel mit der Symmetrieachse des Gasbrenners ein, können aber ±80° davon abweichen.The axes of symmetry of the outflow openings (see Fig. 1, 2 and 3) enclose a 90 ° angle with the axis of symmetry of the gas burner, but can deviate from it by ± 80 °.

Das auf der Abb. 1 mit (1) bezeichnete Rohr ist ein bekanntes Venturirohr, in dem zum gasförmigen Brennstoff die Primärluft gemischt wird. Nach dem Verlassen des Venturirohres strömt das Gas in einen ringförmigen Raum (2), der das Gas zu den Ausströmungsöffnungen (3) verteilt.The tube labeled ( 1 ) in Fig. 1 is a known Venturi tube in which the primary air is mixed with the gaseous fuel. After leaving the Venturi tube, the gas flows into an annular space ( 2 ) which distributes the gas to the outflow openings ( 3 ).

Die Sekundärluft wird der Flamme durch das mit (4) bezeichnete Rohr, durch das Innere des Brenners zugeführt.The secondary air is supplied to the flame through the tube labeled ( 4 ) through the interior of the burner.

Die Abb. 2 zeigt die Draufsicht eines ovalen Gasbrenners, der analog zu dem auf Abb. 1 aufgebaut ist. Fig. 2 shows the top view of an oval gas burner, which is constructed analogously to that in Fig. 1.

Die Abb. 3 und 4 zeigen Gasbrenner, die nach dem gleichen Prinzip wie auf Abb. 1 und 2 arbeiten, sind jedoch bei luftdicht abgeschlossenen Kochmulden verwendbar. Die Bedeutung der Positionsnummern sind gleich, wie auf Abb. 1 und 2. Fig. 3 and 4 show gas burners that work on the same principle as in Fig. 1 and 2, but can be used with airtight hobs. The meaning of the position numbers are the same as in Fig. 1 and 2.
