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 Brennerkreise, 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 Gasleitung 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 Primärluft 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 fitted with feet 1 angle strips 2 and an intermediate base board 3 are gas burner assemblies 4 and associated gas fittings 5 for two hobs attached. The completely identical trained gas burner assemblies 4 each have two burner circuits, namely one Internal burner 6 and arranged around it outside burner 7, and are with its supply channel for the particular for the external burner 7 gas-air mixture V-shaped in the direction of the gas fittings 5 aligned. In the vertical Level to the gas-air guide channel 8 for the outer burner 7 is opposite in the lower region of the burner head of each of the gas burner assemblies 4 a connection for a gas line 9 originating from the respective fitting 5, to a arranged in the burner head of the gas burner assembly 4 gas injector nozzle assembly 10 leads. Over an opening 11 at the bottom of the burner head is the access of the primary air to the gas injector nozzle arrangement released. Im to the inside burner 6 leading channel 12, the gas mixes with the primary air to a good burning mixture. The required secondary air for the internal burner 6 and a required subset of secondary air for the outer burner passes through a Gap opening 19 between the 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.In the gas-air supply passage 8, the coming of the fitting 5 gas is through a gas nozzle 13, which is part of the fitting body, taking with it primary air blown. The intensive mixing of injected gas and sucked Air towards the outer burner 7 takes place in the sufficiently long gas-air supply channel. 8 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 adjust the air supply to the discharge velocity and type of gas used to customize, is the inlet opening of the gas-air supply duct 8 an axially displaceable pipe socket 14 associated with intake funnel 14 ', over which the effective distance of the gas-air supply channel 8 to the nozzle 13th is changeable, whereby the air intake is variable. This pipe socket 14 is actuated via a mounted in the base plate angle lever 15th by a rotary knob assembly 16, which - not shown - operating button from the - also not shown - control panel protrudes.

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 hobs of the hob takes place centrally via a gas line 17, the T-shaped between the two fittings 5 branched to the two valves 5 is connected. The two fittings 5 are symmetrical to each other and arranged. They each contain three gas channel branches, via a rotary knob assembly 18, which via a - not drawn - over the control panel protruding actuator button open and can be closed. One of the gas duct branches in the fitting 5 is for Constant gas flow rate and through the gas supply line 9 to the internal burner 6 assigned. After an initial rotational movement of the rotary knob device 18, this gas channel branch is fully opened, and indeed for the entire further Adjustment of this rotary knob device 18. In the initial position in which this Gas duct branch is open, the flame is ignited at the inner burner. For this purpose, an ignition electrode 20 is arranged in the vicinity of the inner burner 6. The Ignition voltage for generating the spark is generated in the embodiment according to Fig. 1 and Fig. 5 by means of a Zündgenerators 21, which by one of the Rotary knob device e.g. activated by axial impressions contact 24 activated or in the embodiment of FIG. 2 and FIG. 4 by the operation of a Piezo element, which is acted upon by the rotary knob device 18, prepared by the pre-rotation or Eindrückbewegung the rotary knob device for Timing of the opening of the said gas channel branch a striking movement the piezo element 25 is exerted.

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 Figure 1, if necessary, in the vicinity of the inner burner also a thermocouple 22 is arranged, over which - as long as the flame on the internal 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 another rotation angle, after the first gas channel branch for the Internal burner 6 is opened and the flame was ignited on the internal burner, are two more gas duct branches completely open, the nozzle 13 and thus associated with the outer burner 7 of each of the gas burner assembly 4. From The flame of the inner burner 6 forth while the flame of the outer burner is ignited. One of the two associated with the outer burner 7 and the gas nozzle 13th guided gas duct branches is variable with respect to the gas flow rate and may until the end of a predetermined angle of rotation of the rotary knob device be completely closed. The second of the guided to the gas nozzle 13 gas duct branches remains fully open during this time and serves as a secure gas supply for the external burner 7 at minimum heating power.

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 burner for two cooking rings is designed and chosen that as simple and similar components for the two cooking units can be used. The gas fittings 5 as well their associated adjusting mechanisms for the addition of air in the region of the nozzle 13th are mirror images and designed largely consistent; the design of the Two-circuit gas burner assemblies 4 are completely similar. Nevertheless, it allows this Design that the actuators for the spaced cooking areas are brought close together on the front panel and an actuating block form.
