Description

Die Erfindung betrifft eine Gaskochstelle mit einem Gasbrenner, dessen Gasmischkammer von einem Brennerdeckel begrenzt ist, durch dessen Austrittsöffnungen ein Gas-/Luftgemisch aus der Gasmischkammer zur Flammenerzeugung strömt, und mit einer Blendeneinrichtung, die einen durch die Austrittsöffnungen bereitgestellten Strömungsquerschnitt ändert.The invention relates to a gas hob with a gas burner whose gas mixing chamber is delimited by a burner cap, through the outlet openings of which a gas / air mixture flows from the gas mixing chamber for flame generation, and with a diaphragm device which changes a flow cross section provided by the outlet openings.

Aus DE 196 23 529 ist eine gattungsgemäße Gaskocheinrichtung bekannt. Die Gaskocheinrichtung weist eine Kochfläche zum Aufsetzen eines Topfes auf, unterhalb der eine Brennerplatte aus einem Fließ oder einem gelochten Keramikmaterial angeordnet ist. Unterhalb der Brennerplatte ist eine Einrichtung zur Veränderung der Durchflussöffnung für ein Gas-/Luftgemisch vorgesehen. Mittels dieser Einrichtung gibt die Durchflussöffnung immer nur einen bestimmten kreisförmigen Bereich des Vlieses frei, wodurch immer eine bestimmte Brennerfläche sichtbar und im Einsatz ist. Dadurch kann die Brennerfläche dem auf dem Kochfeld aufgesetzten Topf angepasst werden.Out DE 196 23 529 is a generic gas cooking device known. The gas cooking device has a cooking surface for placing a pot, below which a burner plate made of a flow or a perforated ceramic material is arranged. Below the burner plate means for changing the flow opening for a gas / air mixture is provided. By means of this device, the flow opening always releases only a certain circular area of the fleece, whereby a certain burner surface is always visible and in use. This allows the burner surface to be adapted to the pot placed on the hob.

Aus DE 337 192 ist ein Verschluss für ein Kochloch bekannt. Der Verschluss weist Verschlussstücke auf, die nach Art einer Irisblende verstellbar sind. Die Verschlussstücke sind in Abhängigkeit von einer Topfgröße verstellbar.Out DE 337 192 is a closure known for a cooking hole. The closure has closure pieces that are adjustable in the manner of an iris diaphragm. The plugs are adjustable depending on a pot size.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Gaskochstelle mit einem Gasbrenner bereitzustellen, die einfach bedienbar ist.The object of the present invention is to provide a gas hob with a gas burner which is easy to operate.

Die Aufgabe der Erfindung ist durch eine Gaskochmulde mit den Merkmalen des Patentanspruches 1 gelöst. Gemäß dem kennzeichnenden Teil des Patentanspruches 1 ist sinngemäß ein Topfträgerelement der Gaskochmulde verstellbar angeordnet. In Abhängigkeit von der Position des Topfträgerelements ändert sich die Größe eines durch die Austrittsöffnungen gebildeten Heizfeldes der Gaskochstelle. Somit kann in einfacher Weise entsprechend den Heizerfordernissen das Heizfeld der Gaskochstelle geändert werden.The object of the invention is achieved by a gas hob with the features of claim 1. According to the characterizing part of claim 1 mutatis mutandis, a pot carrier element of the gas hob is arranged adjustable. Depending on the position of the pot carrier element, the size of a heating field formed by the outlet openings of the gas hob changes. Thus, the heating field of the gas hob can be changed in a simple manner according to the Heizerfordernissen.

Von Vorteil ist es, wenn das Topfträgerelement unabhängig von seiner Position stets außerhalb der aus den Austrittsöffnungen des Brennerdeckels kommenden Flammen angeordnet sein. Damit begrenzt das Topfträgerelement einen äußeren Flammenumfang zumindest teilweise oder vollständig. Eine übermäßige Erhitzung des Topfträgerelements durch die Flammen ist somit verhindert.It is advantageous if the pot carrier element, regardless of its position, is always located outside the flames coming out of the outlet openings of the burner cap. Thus, the pot support member limits an outer flame circumference at least partially or completely. Excessive heating of the pot carrier element by the flames is thus prevented.

In einer vorteilhaften Weiterbildung kann das Topfträgerelement verhindern, dass ein Gas-/Luftgemisch durch die Austrittsöffnungen des Brennerdeckels austritt. Dies kann dadurch erfolgen, dass das Topfträgerelement die nicht für den Heizbetrieb eingesetzten Austrittsöffnungen überlappt und somit verschließt. Die Austrittsöffnungen des Brennerdeckels sind in einer weiteren Ausführungsform dem Gargutbehältnis zugewandt angeordnet. Dadurch ist eine effektive Erwärmung des Gargutbehältnis ermöglicht.In an advantageous development, the pot carrier element can prevent a gas / air mixture from exiting through the outlet openings of the burner cap. This can be done by the pot carrier element overlapping the outlet openings not used for the heating operation and thus closes. The outlet openings of the burner cover are arranged facing the Gargutbehältnis in a further embodiment. As a result, an effective heating of the Gargutbehältnis is possible.

Für eine Einstellung der Größe des Gesamtströmungsquerschnitts der Austrittsöffnungen des Brennerdeckels kann das Topfträgerelement manuell verstellbar auf dem Brennerdeckel angeordnet sein. Alternativ kann die Gaskochstelle einen Antriebsmotor zum automatischen Verstellen des Topfträgerelements aufweisen. Bei einer Mehrzahl von Topfträgerelementen ist es dabei vorteilhaft, wenn für ein synchrones Verstellen eine Getriebeeinrichtung vorgesehen ist, die die Topfträgerelemente miteinander verbindet. Erfindungsgemäß kann das Topfträgerelement entsprechend einer Größe des darauf abgestellten Gargutbehältnisses angepasst werden. Durch entsprechende Anpassung des Topfträgerelements an die Größe des Gargutbehältnisses wird automatisch auch die Größe des durch die Austrittsöffnungen gebildeten Heizfeldes an die Größe des Gargutbehältnisses angepasst.For adjusting the size of the total flow cross section of the outlet openings of the burner cover, the pot carrier element can be arranged manually adjustable on the burner cover. Alternatively, the gas hob can have a drive motor for automatically adjusting the pot carrier element. In the case of a plurality of pot carrier elements, it is advantageous if, for a synchronous adjustment, a transmission device is provided which connects the pot carrier elements to one another. According to the invention, the pot carrier element can be adapted in accordance with a size of the food container parked thereon. By appropriate adaptation of the pot support member to the size of the Gargutbehältnisses the size of the heating field formed by the outlet openings is automatically adjusted to the size of the Gargutbehältnisses.

Bevorzugt kann eine Heizleistung der Gaskochstelle in Abhängigkeit von der Position des Topfträgerelements eingestellt werden. Sofern sich das Topfträgerelement in einer Position für große Gargutbehältnisse befindet, wird automatisch der Gasbrenner mit einer entsprechend großen Brennerleistung betrieben. Bei einer Position des Topfträgerelements für kleine Gargutbehältnisse erfolgt eine entsprechende Leistungsreduzierung. Zusätzlich kann die Gaskochstelle einen Heizleistungsregler aufweisen, mit dem eine Gaszufuhr zu dem Gasbrenner zur Einstellung von dessen Heizleistung erfolgt.Preferably, a heating power of the gas hob can be adjusted depending on the position of the pot carrier element. If the pot carrier element is in a position for large food containers, the gas burner is automatically operated with a correspondingly large burner output. In a position of the pot carrier element for small Gargutbehältnisse a corresponding reduction in power takes place. In addition, the gas cooker may have a heating power regulator, with which a gas supply to the gas burner for adjusting the heating power takes place.

Nachfolgend ist ein Ausführungsbeispiel der Erfindung anhand der beigefügten Figuren beschrieben.Hereinafter, an embodiment of the invention with reference to the accompanying figures will be described.

Es zeigen:Show it:

Figur 2 eine Seitenschnittansicht entlang der Linie I bis I aus der Figur 1; sowie FIG. 2 a side sectional view along the line I to I of the FIG. 1 ; such as

Figuren 3 und 4 Ansichten der Gaskochstelle von oben. FIGS. 3 and 4 Views of the gas stove from above.

In den Figuren ist eine Gaskochstelle mit einem Gasbrenner 1 gezeigt, dessen prinzipieller Aufbau aus der Figur 2 hervorgeht. Der Gasbrenner 1 ist in einer Montageöffnung 3 einer Muldenplatte 5 aus Glaskeramik eingesetzt. Dem Gasbrenner 1 wird über eine Hauptleitung 7 Gas zugeführt, die mit einem Gasleitungsnetz verbunden ist. Die Hauptleitung 7 mündet in einer Brennerdüse 9. Diese ist über einen Spalt von einem Gas-/Luft-Einlass 11 einer Mischkammer 13 des Gasbrenners 1 beabstandet. Die Mischkammer 13 ist becherartig nach oben offen mit einer hochgezogenen Zylinderwand ausgebildet. Auf einem oberen Rand der Zylinderwand der Mischkammer 13 ist ein scheibenartig ausgebildeter, kreisrunder Brennerdeckel 15 befestigt, dessen Umfangsrand radial über die Zylinderwand hinausragt. Der Umfangsrand des Brennerdeckels 15 liegt über eine Ringdichtung 16 auf der Oberseite der Muldenplatte 5. Nicht dargestellt sind die für die Gaskochstelle üblichen Sicherheitselemente, wie etwa ein Thermoelement und ein zugehöriges Magnetventil zur Sicherheitsabschaltung des Gasbrenners 1 beim Erlöschen einer Flamme.In the figures, a gas hob is shown with a gas burner 1, whose basic structure of the FIG. 2 evident. The gas burner 1 is inserted in a mounting opening 3 of a trough plate 5 made of glass ceramic. The gas burner 1 is supplied via a main line 7 gas, which is connected to a gas line network. The main line 7 opens into a burner nozzle 9. This is spaced by a gap from a gas / air inlet 11 of a mixing chamber 13 of the gas burner 1. The mixing chamber 13 is cup-shaped upwardly open formed with a raised cylinder wall. On an upper edge of the cylinder wall of the mixing chamber 13, a disc-like design, circular burner cap 15 is fixed, the peripheral edge radially over the cylinder wall protrudes. The peripheral edge of the burner cap 15 is above a ring seal 16 on the top of the well plate 5. Not shown are the usual for the gas hob security elements, such as a thermocouple and an associated solenoid valve for safety shutdown of the gas burner 1 when extinguishing a flame.

Der Brennerdeckel 15 weist eine Vielzahl von Austrittsöffnungen 17 auf. Diese bilden auf der Oberseite des Brennerdeckels 15 ein sternförmiges Heizfeld 19, wie es in der Figur 3 gezeigt ist. Auf einer Oberseite des Brennerdeckels 15 liegen drei Topfträgerelemente 21. Die Topfträgerelemente 21 erstrecken sich radial zum Mittelpunkt des Brennerdeckels 15 hin und sind über einen Drehwinkel von 120° zueinander beabstandet. Ferner sind die drei Topfträgerelemente 21 über nicht gezeigte Schienen in radialer Richtung verschiebbar geführt, die in dem Brennerdeckel 15 ausgebildet sind. Damit lassen sich die Topfträgerelemente 21 zwischen den in den Figuren 3 und 4 gezeigten Extrempositionen hin- und her verschieben: In der Figur 3 sind die drei Topfträgerelemente 21 radial nach außen geschoben dargestellt. Dadurch sind alle Austrittsöffnungen 17 des sternförmigen Heizfeldes 19 freigelegt, so dass das Gas-/Luftgemisch für eine Flammenerzeugung durchströmen kann. In der Figur 4 sind die drei Topfträgerelemente 21 radial nach innen geschoben dargestellt und mit ihren frontseitigen Stirnflächen 22 zueinander in Anlage. In dieser Position sind sämtliche Austrittsöffnungen 17 des Heizfeldes 19 durch die Topfträgerelemente 21 überlappt, so dass Gas-/Luftgemisch nicht durch die Gasaustrittsöffnungen 17 strömen kann.The burner cover 15 has a plurality of outlet openings 17. These form on the top of the burner cap 15 a star-shaped heating field 19, as shown in the FIG. 3 is shown. On one upper side of the burner cover 15 are three pot carrier elements 21. The pot carrier elements 21 extend radially to the center of the burner cap 15 and are spaced apart by an angle of rotation of 120 °. Further, the three pot carrier elements 21 are slidably guided in the radial direction via rails, not shown, which are formed in the burner cover 15. Thus, the pot carrier elements 21 between the in the FIGS. 3 and 4 back and forth shown extreme positions: In the FIG. 3 the three pot carrier elements 21 are shown pushed radially outward. As a result, all outlet openings 17 of the star-shaped heating field 19 are exposed, so that the gas / air mixture can flow through for flame generation. In the FIG. 4 the three pot carrier elements 21 are shown pushed radially inwards and with their front end faces 22 to each other in Appendix. In this position are all the outlet openings 17 of the heating field 19 is overlapped by the pot carrier elements 21, so that gas / air mixture can not flow through the gas outlet openings 17.

An ihren Oberseiten weisen die drei Topfträgerelemente 21 jeweils eine radial verlaufende Rippe 23 auf. Gemäß der Figur 2 ist auf den Rippen 23 der drei Topfträgerelemente ein Gargutbehältnis 24 gestellt. Zwischen den Topfträgerelementen 21 sowie außerhalb des Brennerdeckels 15 sind weitere Stützsockel 25 angeordnet. Die Stützsockel 25 dienen zur zusätzlichen Abstützung von Gargutbehältnissen, um ein Kippen derselben zu vermeiden.On their upper sides, the three pot carrier elements 21 each have a radially extending rib 23. According to the FIG. 2 is placed on the ribs 23 of the three pot carrier elements a Gargutbehältnis 24. Between the pot carrier elements 21 and outside the burner cap 15 further support base 25 are arranged. The support base 25 serve for additional support of Gargutbehältnissen to avoid tilting thereof.

Damit ein synchrones Verstellen der Topfträgerelemente 21 gewährleistet ist, sind diese über eine nicht dargestellte Getriebeeinrichtung miteinander verbunden. Beim Verstellen des einen Topfträgerelements 21 werden daher in synchroner Weise die beiden anderen Topfträgerelemente verstellt. Weiterhin kann der Getriebeeinrichtung ein nicht dargestellter Antriebsmotor zugeordnet sein, der mittels des in der Gaskochstelle vorgesehenen Betätigungselements 27 bedient werden kann. Mittels des Betätigungselements 27 kann somit ein Gesamtströmungsquerschnitt des Heizfeldes 19 eingestellt werden.For a synchronous adjustment of the pot carrier elements 21 is ensured, they are connected to each other via a transmission device, not shown. When adjusting the one pot support member 21, therefore, the two other pot support elements are adjusted in a synchronous manner. Furthermore, the transmission device may be associated with a drive motor, not shown, which can be operated by means of the provided in the gas hob actuator 27. By means of the actuating element 27, a total flow cross section of the heating field 19 can thus be adjusted.

Zusätzlich zu dem Betätigungselement 27 weist die Gaskochstelle einen Heizleistungsregler 29 auf. Mittels des Heizleistungsregler 29 kann ein in der Hauptleitung 7 angeordnetes Stellventil 31 betätigt werden, das die Gaszufuhr zum Gasbrenner 1 steuert.In addition to the actuating element 27, the gas hob has a heating power controller 29. By means of the heating power controller 29, a control valve 31 arranged in the main line 7 can be actuated, which controls the gas supply to the gas burner 1.

Zum Start eines Kochvorganges werden die Topfträgerelemente 21 in eine Zwischenposition gebracht, wie sie in der Figur 1 dargestellt ist. In dieser Position sind zumindest einige der Austrittsöffnungen 17 nicht von den Topfträgerelementen 21 überlappt. Bei einer darauffolgenden Betätigung des Heizleistungsreglers 29 wird über das Stellventil 31 in der Hauptleitung 7 ein eingestellter Gasmengenstrom durch die Brennerdüse 9 in Richtung auf den Gas-/Luftgemischeinlass 11 geblasen, wodurch Umgebungsluft in Pfeilrichtung I mit durch den Einlass 11 in die Mischkammer 13 gesaugt wird. Von dort strömt das Gas-/Luftgemisch durch die nicht von den Topfträgerelementen 21 überlappten Austrittsöffnungen 17, die dem Gargutbehältnis 24 zugewandt sind.To start a cooking process, the pot carrier elements 21 are brought into an intermediate position, as in the FIG. 1 is shown. In this position, at least some of the outlet openings 17 are not overlapped by the pot carrier elements 21. In a subsequent operation of the Heizleistungsreglers 29, a set gas flow rate is blown through the burner nozzle 9 in the direction of the gas / air mixture inlet 11 via the control valve 31 in the main line 7, whereby ambient air is sucked in the direction of arrow I through the inlet 11 into the mixing chamber 13 , From there, the gas / air mixture flows through the outlet openings 17 which are not overlapped by the pot carrier elements 21 and which face the cooking product container 24.

Mittels einer nicht gezeigten Zündeinrichtung wird das aus den Austrittsöffnungen 17 austretende Gas-/Luftgemisch zur Ausbildung eines Flammenteppichs entzündet, der das Gargutbehältnis 24 erwärmt.By means of an ignition device, not shown, the emerging from the outlet openings 17 gas / air mixture is ignited to form a flame carpet, which heats the Gargutbehältnis 24.
