Description

Die zur Zeit gebräuchlichsten Kochstellen für Gasherde weisen eine Haupt- und Halteflamme auf, wobei die Halteflamme eine bestimmte Nennwärmeleistung nach der Norm nicht überschreiten darf. Diese Anforderung wird von den gebräuchlichen Kochstellenbrennern zwar erfüllt, jedoch wird von Geräteherstellern immer wieder eine möglichst niedrigere Kleinstellrate gefordert, wobei die Größe der Topfflächenbeheizung nicht gemindert werden soll, um einen möglichst großen Wirkungsgrad zu behalten, so daß die Kleinstellrate ein wichtiger verbesserungswürdiger Punkt ist.The most commonly used cooking ranges for gas stoves have a main and holding flame, the holding flame must not exceed a certain nominal heat output according to the standard. Although this requirement is met by the conventional hotplate burners, device manufacturers repeatedly demand the lowest possible small adjustment rate, whereby the size of the pot surface heating should not be reduced in order to retain the greatest possible efficiency, so that the small adjustment rate is an important point worthy of improvement.

Ein Gasbrenner mit übereinander liegender Haupt- und Sparflamme ist aus der Patentschrift DE 580 338 bekannt.A gas burner with superimposed main and pilot flame is known from the patent DE 580 338.

Bei den herkömmlichen Kochstellenbrennern ist eine Kleinstellrate je nach Gasart von ca. 20 bis 25 % der Nennbelastung zu erreichen. Die Forderungen der Gerätehersteller liegen jedoch teilweise bei 10 bis 12 % der Nennbelastung.For conventional hotplate burners, a small adjustment rate of approx. 20 to 25% of the nominal load can be achieved, depending on the gas type. However, the requirements of the device manufacturers are sometimes 10 to 12% of the rated load.

Desweiteren sind auch Brennerarten bekannt, die mit zwei voneinander getrennten Gaseingängen arbeiten und dabei einen großen Außenbrenner und einen kleinen Innenbrenner beinhalten.Furthermore, burner types are known which work with two separate gas inputs and thereby include a large external burner and a small internal burner.

Diese Brenner haben zwar die Möglichkeit eine sehr niedrige Kleinstellrate zu erreichen, sind aber aufgrund ihrer Konstruktion sehr aufwendig, da diese Brenner getrennt voneinander wirken, wobei die Überzündung von einem zum anderen Brenner sehr problematisch und aufwendig ist. Ein weiterer Nachteil ergibt sich aus der Größe des Innenbrenners, da der relativ kleine Flammenkranz für eine möglichst große Topfflächenbeheizung nicht wirkungsvoll arbeitet und dadurch ein sehr geringer Wirkungsgrad erzeugt wird.Although these burners have the opportunity to achieve a very low Kleinstellrate, but because of their design very expensive, since these burners act separately, the over-ignition of one to the other burner is very problematic and expensive. Another disadvantage arises from the size of the internal burner, since the relatively small flame ring does not work effectively for the largest possible pot surface heating and thus a very low efficiency is generated.

Der Erfindung liegt die Aufgabe zugrunde, eine Kochstelle für Gasherde zu schaffen, deren Brenner mit konstruktiv einfachen Mitteln eine optimale Ausnutzung der zugeführten Wärmeenergie insbesondere im Kleinlastbereich mit möglichst geringer Durchflußrate im Vergleich zur Nennbelastung ermöglichen und dabei eine möglichst große und gleichmäßige Topfflächenbeheizung sicherstellen.The invention has for its object to provide a hotplate for gas stoves, the burner with structurally simple means optimal utilization of heat energy supplied especially in the low load range with the lowest possible flow rate compared to the rated load and thereby ensure the largest possible and uniform pot surface heating.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine Kochstelle für Gasherde, deren Brenner mit unterstöchiometrischer Primärluftvormischung betrieben wird, bestehend aus zwei übereinander Gasluftgemisch-Versorgungskammern, die beide durch einen an der Brennerkopfunterseite angebrachten, jeweils getrennten Gaseingang mit einer Gasluftmisch-Einrichtung zur Bildung des Gasluftgemisches für eine Haupt- und Halteflammen erzeugen, und der unter dem oberen Brennerring liegende zweite Brennerring der unter Gasluftgemisch-Versorgungskammer an seinem äußeren Durchmesser eine rundum spaltförmige Gasaustrittsöffnung zur Auflage des Brennerkopfes hin aufweist, der die Simmerflamme erzeugt, und die beiden Außendurchmesser der Brennerringe im Flammenbereich die gleiche Größe aufweisen.This object is achieved in that a cooking point for gas stoves, the burner is operated with substoichiometric Primärluftvormischung consisting of two superimposed gas air mixture supply chambers, both attached by a attached to the burner head bottom, each separate gas inlet with a gas-mixing device for forming the gas mixture for generating a main and holding flames, and lying under the upper burner ring second burner ring of the gas mixture under supply chamber at its outer diameter has an all-round gap-shaped gas outlet opening for supporting the burner head, which generates the Simmerflamme, and the two outer diameter of the burner rings in the flame area the same size.

Bei einem solchen Gasbrenner kann der unter dem ersten Brennerring liegende zweite Brennerring mit seiner am Außenumfang liegenden spaltförmigen Öffnung unabhängig von der Haupt- und Halteflamme arbeiten.In such a gas burner, the second burner ring lying below the first burner ring can operate independently of the main and holding flame with its gap-shaped opening lying on the outer circumference.

Besonders vorteilhaft ist auch, wenn die Simmerflamme unterhalb des Flammenaustritts der Haupt- und Halteflamme liegt, da bei Wiedereinschaltung der Halte- oder Hauptflamme eine absolut sichere und sofortige Überzündung des austretenden Gasflusses erfolgt.It is also particularly advantageous if the Simmerflamme is below the flame outlet of the main and holding flame, as when restarting the holding or main flame is a completely safe and immediate over-ignition of the exiting gas flow.

Der Gasbrenner weist an der Oberseite eine runde Abdeckplatte 8 auf, deren Unterseite am Außenrand einen vorstehenden Zentrierrand 9 aufweist, der in eine am oberen Brennering 3 vorgesehene rundum laufende Vertiefung eingreift und sich so zentrisch zentriert.The gas burner has at the top of a round cover plate 8, the underside of the outer edge has a projecting centering 9, which engages in a provided on the upper burner ring 3 all-round recess and centered so centric.

Der obere Brennering 3 weist auf seiner Unterseite gleichmäßig verteilte nach außen hin schräg aussteigende Gasaustrittsöffnungen 7 auf, die die Haupt- und Halteflamme erzeugen und von der oberen Gasluftgemisch-Versorgungskammer 1 mit dem dazugehörenden zentrisch unter dem Brennerkopf 6 liegenden Gaseingang 1a versorgt werden. Am äußeren Ende der Gasaustrittsöffnungen ist oberhalb eine rundum laufende Nutrille 10 angebracht, die bei brennender Hauptflamme die sonst vorhandene Neigung gegen Abreißen der Flammen und den Brenner gegen Zurückschlagen unterstützt. Auf der inneren Unterseite des oberen Brennerringes 3 sind mindestens drei oder mehrere Arretiernocken 11 angebracht, die in einen umlaufenden Zentrierdurchmesser 12, des unter dem oberen Brennerring 3 liegenden Brennerringes 4 eingreifen und somit den oberen Brennerring 3 mit dem darunter liegenden Brennerring 4 in einer zentrischen Lage hält. Einer dieser Zentriernocken 11 kann als Arretiernocken 11a ausgebildet sein, der in eine im Brennerring 4 vorhandene Nut 11b eingreift.The upper burner ring 3 has on its underside evenly distributed outwardly obliquely rising gas outlet openings 7, which are the main and holding flame generate and supplied by the upper gas-air mixture supply chamber 1 with the associated centrally located below the burner head 6 gas inlet 1a. At the outer end of the gas outlet openings above a running Nutrille 10 is mounted, which supports the otherwise existing tendency against tearing of the flames and the burner against repelling when burning main flame. On the inner bottom of the upper burner ring 3 at least three or more locking cams 11 are mounted, which engage in a circumferential centering diameter 12 of the burner ring lying below the upper burner ring 3 4 and thus the upper burner ring 3 with the underlying burner ring 4 in a central position holds. One of these centering cams 11 may be formed as locking cams 11 a, which engages in an existing groove in the burner ring 4 b.

Als Variante der Abdeckplatte 8 und des oberen Brennerringes 3 besteht die Möglichkeit, Abdeckplatte und Brennerring aus einem Teil herzustellen. Die an der Unterseite des oberen Brennerrings aus einem Teil herzustellen. Die an der Unterseite des oberen Brennerringes 3 vorhandene nach außen hin schräg ansteigende und durch die Gasaustrittsöffnungen 7 unterbrochene Auflagefläche 13a liegt auf der ebenfalls nach außen hin schräg ansteigenden Auflagefläche 13 des unter dem oberen Brennerringes 3 liegenden Brennerringes 4 metallisch auf und sichert so den gewünschten Gasaustritt durch die Gasaustrittsöffnungen 7 an der Unterseite des oberen Brennerringes 3. An der Unterseite des unteren Brennerringes 4 ist ebenfalls eine nach außen hin schräg ansteigende umlaufende Fläche 14 vorgesehen, die zu dem darunter liegenden Brennerkopf 6 eine rundumlaufende spaltähnliche Öffnung zuläßt.As a variant of the cover plate 8 and the upper burner ring 3, it is possible to produce cover plate and burner ring of one part. The one at the bottom of the upper burner ring to make a part. The on the underside of the upper burner ring 3 existing outwardly inclined rising and interrupted by the gas outlet openings 7 support surface 13a is on the also outwardly inclined rising support surface 13 of the underlying burner ring 3 burner ring 4 metallic and thus secures the desired gas outlet On the underside of the lower burner ring 4 is also an outwardly obliquely rising circumferential surface 14 is provided, which allows the underlying burner head 6 a circumferential gap-like opening.

Desweiteren sind an der Unterseite des unteren Brennerringes 4 zwei nach unten gleich hoch vorstehende, rundumlaufende zylindrisch angeordnete Ringe 16, 17 angeordnet, die mit ihrer Unterseite gegen eine Planfläche 18 im Brennerkof 6 metallisch aufliegen und die untere Gasluftgemisch-Versorgungskammer mit dem zugehörigen Gaseingang 2a gegen den zentrisch angeordneten Gaseingang 1a und die obere Gasluftgemisch-Versorgungskammer 1 abdichten. Durch die beiden zylindrisch angeordneten, nach unten vorstehenden umlaufenden Ringe 16, 17 am unteren Brennerring 4 wird die umlaufende Spaltöffnung 5 zwischen dem unteren Brennerring 4 und Brennerkopf 6 höhenmäßig bestimmt. An dem äußeren vorstehenden umlaufenden Ring 16 an der Unterseite des Brennerringes 4 sind mehrere radiale Gasaustrittsöffnungen 19 angebracht, die die Gasversorgung von der unteren Versorgungskammer 2 zur Spaltöffnung 5 zwischen dem unteren und oberen Brennerring 3, 4 gewährleisten. Um eine saubere und am Umfang gleichmäßige Gasversorgung zwischen Brennerkopf 6 und unterem Brennerring 4 für die Spaltöffnung zu gewährleisten, sind am äußeren Umfang des vorstehenden Ringes 16 am unteren Brennerring 4 mindestens 3 oder mehrere nach außen hin vorstehende Nocken 20 zur Mittenzentrierung angebracht.Furthermore, at the bottom of the lower burner ring 4, two downwardly equally high projecting, circumferentially cylindrical rings 16, 17 are arranged, the metallic rest with its underside against a flat surface 18 in Brennerkof 6 and the lower gas mixture supply chamber with the associated gas inlet 2a against Seal the centrally arranged gas inlet 1a and the upper gas-air mixture supply chamber 1. By the two cylindrical, downwardly projecting circumferential rings 16, 17 on the lower burner ring 4, the circumferential gap opening 5 between the lower burner ring 4 and burner head 6 is determined in terms of height. On the outer protruding circumferential ring 16 on the underside of the burner ring 4 a plurality of radial gas outlet openings 19 are mounted, which ensure the gas supply from the lower supply chamber 2 to the gap opening 5 between the lower and upper burner ring 3, 4. To ensure a clean and circumferentially uniform gas supply between the burner head 6 and lower burner ring 4 for the gap opening, at least 3 or more outwardly projecting cam 20 are mounted on the outer periphery of the protruding ring 16 on the lower burner ring 4 for centering.

Der Brennerkopf 6 weist in seinem Zentrum eine Aufnahmebohrung 21 für eine Luftmischhülse 22 mit Außengewinde des zentral liegenden Gaseingangs 1a auf, welche gleichzeitig den Brennerkopf mit der Herdmulde und dem darunter liegenden Düsenträger 23 mit Düse 23a fest verschraubt.The burner head 6 has in its center a receiving bore 21 for an air mixing sleeve 22 with external thread of the centrally located gas inlet 1a, which simultaneously screwed the burner head with the hob and the underlying nozzle carrier 23 with nozzle 23a.

Zur Abdichtung zwischen Brennerkopf 6 und Gasmulde ist an der Unterseite des Brennerkopfes 6 umlaufend eine Ringnut 25 eingebracht, die einen Dichtring 25 aufnimmt, um ein evtl. überlaufendes Kochgut unter die Herdmulde zu verhindern. Desweiteren ist an der Unterseite des Brennerkopfes 6 radial seitlich zum ersten im Zentrum liegenden Gaseingang 1a ein Rohrstutzen 26 mit einem Zentrieransatz 27 angebracht, der als Gaseingang 2a für die Versorgung der unteren Gasversorgungskammer 2 im Brenner dient. Die Mittenzentrierung zur Düse 28 im Düsenträger 29 wird durch den äußeren Durchmesser des Rohrstutzens 26 am Brennerkopf 6 und durch die Aufnahmebohrung 30 in der darunter liegenden Luftmischhülse 31 gesichert.For sealing between the burner head 6 and gas well an annular groove 25 is circumferentially introduced at the bottom of the burner head 6, which receives a sealing ring 25 to prevent any overflowing food under the hob. Furthermore, at the bottom of the burner head 6 radially laterally to the first located in the center of the gas inlet 1 a Pipe socket 26 mounted with a spigot 27, which serves as a gas inlet 2a for the supply of the lower gas supply chamber 2 in the burner. The centering of the nozzle 28 in the nozzle carrier 29 is secured by the outer diameter of the pipe socket 26 on the burner head 6 and the receiving bore 30 in the underlying air mixing sleeve 31.

Der am oberen Ende des Rohrstutzens 26 angebrachte Zentrieransatz 27 gewährleistet in radialer Weise eine genaue Brennerarretierung, die für die Montage des Brennerkopfes 6 den unter der Herdmulde montierten Luftmischhülsen 22, 31 und Düsenträgern 23, 29 wichtig ist.The attached at the upper end of the pipe socket 26 centering projection 27 ensures in a radial manner a precise Brennerarretierung that is important for the assembly of the burner head 6 mounted under the hob air mix sleeves 22, 31 and nozzle holders 23, 29.
