Auf einem Grundgestell, bestehend aus zwei mit Füßen 1 bestückten Winkelleisten 2 und einer dazwischenliegenden Basisplatine 3 sind Gasbrenneranordnungen 4 und dazugehörige Gasarmaturen 5 für zwei Kochstellen befestigt. Die völlig gleichartig ausgebildeten Gasbrenneranordnungen 4 weisen je zwei Brennekreise, nämlich einen Innenbrenner 6 und einen darum herum angeordneten Außenbrenner 7, auf und sind mit ihrem Zuführungskanal für das für den Außenbrenner 7 bestimmte Gas-Luft-Gemisch V-förmig in Richtung auf die Gasarmaturen 5 ausgerichtet. In der senkrechten Ebene zum Gas-Luft-Führungskanal 8 für den Außenbrenner 7 ist gegenüberliegend im unteren Bereich des Brennerkopfes jeder der Gasbrenneranordnungen 4 ein Anschluß für eine von der jeweiligen Armatur 5 ausgehenden Gasleistung 9 vorgesehen, die zu einer im Brennerkopf der Gasbrenneranordnung 4 angeordnete Gasinjektor-Düsenanordnung 10 führt. Über eine Öffnung 11 an der Unterseite des Brennerkopfes ist der Zutritt der Primärlutt zur Gasinjektor-Düsenanordnung freigegeben. Im zum Innenbrenner 6 führenden Kanal 12 vermischt sich das Gas mit der Primärluft zu einem gut brennenden Gemisch. Die benötigte Sekundärluft für den Innenbrenner 6 als auch eine erforderliche Teilmenge von Sekundärluft für den Außenbrenner gelangt durch eine Spaltöffnung 19 zwischen Innenbrenner 6 und Außenbrenner 7 zu den den Flammbereichen. On a base frame, consisting of two angle strips 2 equipped with feet 1 and an intermediate base board 3 are gas burner assemblies 4 and associated gas fittings 5 attached for two hotplates. The completely identical trained gas burner arrangements 4 each have two combustion circuits, namely one Inner burner 6 and an outer burner 7 arranged around it, and are with its feed channel for the gas-air mixture intended for the external burner 7 V-shaped in the direction of the gas fittings 5. In the vertical Level to the gas-air guide channel 8 for the external burner 7 is opposite in the lower area of the burner head of each of the gas burner arrangements 4, a connection provided for a gas output 9 starting from the respective fitting 5, the gas injector nozzle arrangement arranged in the burner head of the gas burner arrangement 4 10 leads. Via an opening 11 on the underside of the burner head access of the primary air to the gas injector nozzle arrangement is released. Im to the inner burner 6 leading channel 12, the gas mixes with the primary air to a good burning mixture. The required secondary air for the inner burner 6 as well as one Part of the secondary air required for the external burner passes through a Gap opening 19 between inner burner 6 and outer burner 7 to the flame areas.

In den Gas-Luft-Zuführungskanal 8 wird das aus der Armatur 5 kommende Gas durch eine Gasdüse 13, die Bestandteil des Armaturkörpers ist, unter Mitnahme von Primärluft eingeblasen. Die intensive Vermischung von eingeblasenem Gas und angesaugter Luft hin zum Außenbrenner 7 findet im genügend langen Gas-Luft-Zuführungskanal 8 statt.The gas coming from the fitting 5 is passed through into the gas-air supply channel 8 a gas nozzle 13, which is part of the fitting body, taking primary air blown in. The intensive mixing of injected gas and suction Air to the external burner 7 is found in the gas-air supply duct 8 which is long enough instead of.

Um die Luftzufuhr auf die Ausströmgeschwindigkeit und Art des verwendeten Gases individuell anpassen zu können, ist der Eingangsöffnung des Gas-Luft-Zuführungskanales 8 ein axial verschieblicher Rohrstutzen 14 mit Ansaugtrichter 14' zugeordnet, über welchen der wirksame Abstand des Gas-Luft-Zuführungskanals 8 zur Düse 13 hin veränderbar ist, wodurch auch die Luftansaugung veränderbar ist. Dieser Rohrstutzen 14 ist betätigbar über einen in der Basisplatine gelagerten Winkelhebel 15 durch eine Drehknebelanordnung 16, deren - nicht dargestellter - Betätigungsknopf aus der - ebenfalls nicht dargestellten - Bedienblende herausragt.To the air supply on the outflow speed and type of gas used To be able to individually adapt is the inlet opening of the gas-air supply duct 8 an axially displaceable pipe socket 14 with an intake funnel 14 'is assigned, over which the effective distance of the gas-air supply channel 8 to the nozzle 13 is changeable, whereby the air intake can also be changed. This pipe socket 14 can be actuated via an angle lever 15 mounted in the base plate by a rotary knob arrangement 16, the - not shown - operating button protrudes from the control panel - also not shown.

Die Gaszufuhr für die Gasbrenner-Anordnungen 4 der beiden Kochstellen des Kochfeldes erfolgt zentral über eine Gasleitung 17, die zwischen den beiden Armaturen 5 T-förmig verzweigt an die beiden Armaturen 5 angeschlossen ist. Die beiden Armaturen 5 sind symmetrisch zueinander aufgebaut und angeordnet. Sie enthalten je drei Gaskanalverzweigungen, die über eine Drehknebelanordnung 18, die über einen - nicht gezeichneten - über die Bedienblende hinausragenden Betätigungsknopf geöffnet und geschlossen werden können. Eine der Gaskanalverzweigungen in der Armatur 5 ist für konstanten Gasdurchsatz ausgelegt und über die Gaszuführungsleitung 9 dem Innenbrenner 6 zugeordnet. Nach einer Anfangsdrehbewegung der Drehknebelvorrichtung 18 wird diese Gaskanalverzweigung völlig geöffnet, und zwar für den gesamten weiteren Verstellweg dieser Drehknebelvorrichtung 18. In der Anfangsposition, in der diese Gaskanalverzweigung geöffnet ist, ist auch die Flamme am Innenbrenner zündbar. Dazu ist im Nahbereich des Innenbrenners 6 eine Zündelektrode 20 angeordnet. Die Zündspannung zur Erzeugung der Zündfunken wird generiert bei der Ausführungsform nach Fig. 1 und Fig. 5 mit Hilfe eines Zündgenerators 21, welche durch einen von der Drehknebelvorrichtung z.B. durch axiales Eindrücken betätigbaren Kontakt 24 aktiviert wird oder bei der Ausführungsform nach Fig. 2 und Fig. 4 durch die Betätigung eine Piezoelements, auf das die Drehknebelvorrichtung 18 einwirkt, indem vorbereitet durch die Vorab-Drehbewegung oder Eindrückbewegung der Drehknebelvorrichtung zum Zeitpunkt der Öffnung der besagten Gaskanalverzweigung eine Schlagbewegung auf das Piezoelement 25 ausgeübt wird. The gas supply for the gas burner arrangements 4 of the two hotplates of the hob takes place centrally via a gas line 17, which is T-shaped between the two fittings 5 is connected to the two fittings 5. The two fittings 5 are constructed and arranged symmetrically to one another. They each contain three Gas channel branches, which have a rotary knob arrangement 18, which have a - not shown - open operating button protruding beyond the control panel and can be closed. One of the gas duct branches in the valve 5 is designed for constant gas throughput and 9 via the gas supply line Internal burner 6 assigned. After an initial rotary movement of the rotary toggle device 18 this gas channel branching is opened completely, for the whole further adjustment path of this rotary toggle device 18. In the initial position, in the this gas channel branch is open, is also the flame on the inner burner ignitable. For this purpose, an ignition electrode 20 is arranged in the vicinity of the inner burner 6. The ignition voltage for generating the ignition sparks is generated at the Embodiment according to FIGS. 1 and 5 with the aid of an ignition generator 21, which by one of the rotary toggle devices e.g. operable by axial pushing Contact 24 is activated or in the embodiment of FIGS. 2 and 4 by the Actuation of a piezo element on which the rotary toggle device 18 acts by prepared by the pre-rotation or push-in movement of the Rotary knob device at the time of opening of said gas channel branch a striking movement is exerted on the piezo element 25.

Wie aus Fig 1 ersichtlich ist, ist bedarfsweise im Nahbereich des Innenbrenners auch ein Thermoelement 22 angeordnet, über welches - solange die Flamme am Innenbrenner 6 vorhanden ist - ein Hauptventil 23 für den Gasaustritt geöffnet gehalten wird.As can be seen from Fig. 1, if necessary, is also in the vicinity of the internal burner a thermocouple 22 is arranged over which - as long as the flame on the inner burner 6 is present - a main valve 23 is kept open for the gas outlet.

Nach einem weiteren Drehwinkel, nach dem die erste Gaskanalverzweigung für den Innenbrenner 6 geöffnet ist und die Flamme am Innenbrenner gezündet wurde, werden zwei weitere Gaskanalverzweigungen vollständig geöffnet, die der Düse 13 und somit dem Außenbrenner 7 jedem der Gasbrenneranordnung 4 zugeordnet sind. Von der Flamme des Innenbrenners 6 her wird dabei die Flamme des Außenbrenners gezündet. Einer der beiden dem Außenbrenner 7 zugeordneten und an die Gasdüse 13 geführten Gaskanalverzweigungen ist bezüglich der Gasdurchflußmenge veränderlich und kann bis zum Ende eines vorgegebenen Drehwinkels der Drehknebelvorrichtung völlig geschlossen werden. Der zweite der an die Gasdüse 13 geführten Gaskanalverzweigungen bleibt während dessen voll geöffnet und dient der gesicherten Gaszufuhr für den Außenbrenner 7 bei Minimal-Heizleistung.After a further angle of rotation, after which the first gas channel branching for the Inner burner 6 is open and the flame has been ignited on the inner burner two further gas channel branches fully opened, the nozzle 13 and thus the outer burner 7 are assigned to each of the gas burner arrangements 4. From the flame of the inner burner 6, the flame of the outer burner is ignited. One of the two assigned to the external burner 7 and to the gas nozzle 13 guided gas channel branches is variable with regard to the gas flow rate and can until the end of a predetermined angle of rotation of the rotary toggle device be completely closed. The second of the gas channel branches led to the gas nozzle 13 remains fully open during this time and is used for secure gas supply for the external burner 7 at minimum heating output.

Die Ausgestaltung und Anordnung der Gasbrenner für zwei Kochstellen ist so konzipiert und gewählt, daß auf möglichst einfache und gleichartige Bauelemente für die beiden Kochstelleneinheiten zurückgegriffen werden kann. Die Gasarmaturen 5 sowie deren zugeordnete Verstellmechanismen für die Luftzugabe im Bereich der Düsen 13 sind spiegelbildlich und weitestgehend übereinstimmend ausgestaltet; die Bauform der Zweikreis-Gasbrenneranordnungen 4 sind völlig gleichartig. Trotzdem erlaubt es diese Bauform, daß die Betätigungselemente für die auseinanderliegenden Kochstellenbereiche an der Bedienfront nahe zusammengerückt sind und einen Betätigungsblock bilden.The design and arrangement of the gas burners for two hotplates is designed in this way and chosen that for simple and similar components for the two hotplate units can be used. The gas fittings 5 as well their associated adjustment mechanisms for the addition of air in the area of the nozzles 13 are mirror images and largely identical; the design of the Two-circuit gas burner arrangements 4 are completely identical. Nevertheless, it allows this Design that the actuating elements for the cooking area areas apart close together on the front panel and an actuation block form.
