Die Erfindung betrifft einen Gasbrenner mit automatischer Zündung für Kochstellen gemäß dem Oberbegriff von Anspruch 1.The invention relates to a gas burner with automatic ignition for hot plates according to the preamble of claim 1.
Aus der US 5,492,469 ist ein Gasbrenner mit einer Zündanordnung bekannt. Die Zündanordnung weist einen Zünder auf, der einen rohrartigen wärmebeständigen Grundkörper mit einer Elektrode umfasst, der in einem Luftkanal angeordnet ist, durch den Luft zu der Elektrode geführt wird.A gas burner with an ignition arrangement is known from US Pat. No. 5,492,469. The Ignition assembly has an igniter that has a tubular heat resistant Includes base body with an electrode, which is arranged in an air duct the air is led to the electrode.
Weitere Gasbrenner sind beispielsweise aus den DE-A-41 08 296, 42 03 668 und 41 03 048 bekannt.Further gas burners are for example from DE-A-41 08 296, 42 03 668 and 41 03 048 known.
Durch die Erfindung soll die Aufgabe gelöst werden, den automatischen Zündvorgang des Gasbrenners zu verbessern und insbesondere eine sichere Zündung zu gewährleisten, so daß das Erfordernis von mehreren Zündversuchen vermieden wird.The object of the invention is to achieve the automatic ignition process to improve the gas burner and in particular to ensure reliable ignition, so that the need for multiple ignition attempts is avoided.
Diese Aufgabe wird gemäß der Erfindung durch die kennzeichnenden Merkmale von Anspruch 1 gelöst.This object is achieved according to the invention by the characterizing features of Claim 1 solved.
Weitere Merkmale der Erfindung sind in den Unteransprüchen enthalten. Durch sie wird ebenfalls der Zündvorgang verbessert und insbesondere erreicht, daß bei Einschalten des Gasbrenners sein Gas-Luft-Gemisch sicher gezündet wird, so daß es nicht erforderlich wird, mehrere Zündversuche zu starten.Further features of the invention are contained in the subclaims. Through it the ignition process is also improved and in particular achieved that when switching on the gas burner will ignite its gas-air mixture safely so that it it is not necessary to start several ignition attempts.
Die Erfindung wird im folgenden mit Bezug auf die Zeichnungen anhand einer bevorzugten Ausführungsform als Beispiel beschrieben.
- Fig. 1
- zeigt einen Axialschnitt durch einen Gasbrenner mit automatischer Zündung gemäß der Erfindung für Kochstellen eines Gasherdes.
- Fig. 1
- shows an axial section through a gas burner with automatic ignition according to the invention for cooking areas of a gas range.
Der in den Zeichnungen dargestellte Gasbrenner hat einen Gas-Luft-Gemisch-Raum 2
zwischen einem pilzförmigen Unterteil 4 und einem Deckel 6. In einer ringförmigen
Umfangswand 8 des Gemischraumes 2 ist eine Vielzahl von Brennerdüsen gebildet,
von welchen in der Zeichnung nur eine dargestellt ist, welche als Zünddüse 10 dient
und den Gemischraum 2 mit einem Zündraum 12 verbindet. Der Zündraum 12 wird auf
seiner radialen Innenseite von der Umfangswand 8, oben von einem Teil des Deckels
6 und unten von einem Teil des Unterteils 4 begrenzt und ist auf seiner radial äußeren
Seite zur Außenumgebung offen, so daß die Zündflamme nach außen austreten kann
und nach dem Zündvorgang auch als eine der Brennerflammen wirkt.The gas burner shown in the drawings has a gas-air mixture space 2
between a mushroom-shaped
In den Zündraum 12 ragt das mit einem Zündstift 14 versehene obere Ende einer
Zündkerze 16. Beim Einschalten des Gases wird automatisch zwischen dem Zündstift
14 und dem Gehäuse der Zündkerze 16 ein Zündfunke erzeugt, welcher das Gas-Luft-Gemisch
zündet. Anstelle einer Zündkerze 16 können auch andere Arten von Zündern
verwendet werden, beispielsweise Glühzünder mit einem Glühelement anstelle eines
Zündstiftes 14. Der Zünder, im vorliegenden Falle der Zündstift 14, ist stromabwärts
der Zünddüse 10 in ihrem Gas-Luft-Strömungsweg angeordnet, so daß der Gas-Luft-Gemischstrom
18 über den Zündstift 14 strömt. Am Deckel 6 ist gegenüber vom
Zündstift 14 ein Vorsprung 20 gebildet, welcher vom Deckel 6 in Richtung zum Zündstift
14 wegragt und eine Prallplatte bildet, welche den Gas-Luft-Gemischstrom der
Zünddüse 10 verwirbelt und in Richtung zum Zündstift 14 ablenkt.The upper end, provided with an
Der Düsenkanal der Zünddüse 10 hat am stromaufwärtigen Anfang einen kurzen zylindrischen
Abschnitt und ist dann bis zu seinem stromabwärtigen Ende trichterartig
erweitert, so daß er als Diffusor wirkt und das Gas-Luft-Gemisch "aufreißt". Diese Diffusorwirkung
der Zünddüse 10 und die Prallplatte 20 haben eine bessere Zündung des
Gemisches am Zündstift 14 zur Folge und vermeidet, daß mehrfach vergeblich gezündet
werden muß beim Einschalten des Gasbrenners.The nozzle channel of the
Das Gas wird dem Gemischraum 2 von einer Gasdüse 22 über einen zentralen Rohrstutzen
24 zugeführt und saugt zwischen der Gasdüse 22 und dem Rohrstutzen 24
aus der Außenumgebung Luft an, sogenannte Primärluft 26. Zur Verbrennung dient
nicht nur diese Primärluft 26, sondern auch die Umgebungsluft im Bereich der Brennerdüsen,
von welchen nur die Zünddüse 10 dargestellt ist. Außer den Brennerdüsen
10 in der Ebene der Zünddüse 10 können unterhalb von ihnen weitere Gasauslaßöffnungen
28 vorgesehen sein, durch welche aus dem Gemischraum 2 Gas-Luft-Gemisch
zur Bildung von Hilfsflammen bei hohem Hitzebedarf austreten kann.The gas is the mixture chamber 2 from a
Gemäß einem besonderen Merkmal des Gasbrenners sind ein oder mehrere Luftansaugkanäle
30 vorgesehen, von welchen die Zeichnung nur einen zeigt. Dieser Luftansaugkanal
ist einerseits mit der Außenluft in Verbindung und mündet andererseits an
einer zwischen der Zünddüse 10 und der Zündkerze 16 gelegenen Stelle in den Zündraum
12. Der stromabwärtige Abschnitt des Luftansaugkanals 30 ist unter einer solchen
Richtung in den Zündraum 12 gerichtet, daß die angesaugte Zusatzluft 32 an einer
zwischen der Zünddüse 10 und dem Zündstift 14 gelegenen Stelle in den Gas-Luft-Gemischstrom
der Zünddüse 10 gesaugt wird. Vorzugsweise ist der Luftansaugkanal
30 so ausgerichtet, daß mindestens ein Teil der Zusatzluft 32 direkt auf den
Zündstift 14 gerichtet ist. Die zusätzliche Außenluft 32 des Luftansaugkanals 30 reduziert
im Bereich des Zündstiftes 14 den Gasanteil des Gemisches. Dadurch wird zwar
der Verbrennungs-Wirkungsgrad des Gemisches der Zünddüse 10 verschlechtert, jedoch
der Zündvorgang verbessert. Die zusätzliche Luft des Luftansaugkanals 30 hat
eine um so bessere Wirkung, je besser sie mit dem Gas-Luft-Strom der Zünddüse 10
vermischt wird. Die Vermischung wird durch die Diffusionswirkung der Zünddüse 10
und durch die Verwirbelung an der Prallplatte 20 wesentlich verbessert.According to a special feature of the gas burner, there are one or more
Der Luftansaugkanal 30 ist mit einem Winkel von weniger als 90° schräg auf den Weg
des Gemischstromes 18 der Zünddüse 10 gerichtet, wobei die Winkelspitze in Strömungsrichtung
des Gemischstromes zeigt.The
Die Umfangswand 8 des Gasraumes 2 ist durch einen ringartigen Vorsprung des
Deckels 6 gebildet, jedoch sind auch andere Ausführungsformen möglich.The
