It thereby releases an electric switch (8) controlling a solenoid valve (9) opening and closing gas flow to the burner (1). The burner arrangement is integrated into a cooker closed on the inside of the oven. The system consists of an oven switch, burner, ball pin and grille and forming a closed system.

Description

Die Erfindung bezieht sich auf eine Brennervorrichtung, der im Oberbegriff des Anspruches näher bezeichneten Art. Im gewerblichen Großküchenbereich werden derzeit insbesondere Gasherde mit großen Brennerleistungen eingesetzt, bei denen der Brenner selbst in der Regel durch manuelle Betätigung eines Schalters entflammt wird, soweit wie im Großküchenbereich in der Regel behördlich vorgeschrieben eine Zündflamme vorhanden ist. Danach verbleibt der Brenner auch in Betrieb, soweit während kürzerer, aber auch längerer Zeiten der Kochtopf, die Bratpfanne etc. vom Brennerrost genommen wird.The invention relates to a burner device of the type specified in the preamble of the claim. In commercial commercial kitchens, in particular gas stoves with large burner outputs are currently used, in which the burner itself is usually ignited by manual actuation of a switch, as far as in the commercial kitchen area A pilot light is usually required by the authorities. The burner then remains in operation as long as the saucepan, frying pan etc. are removed from the burner grate during shorter and longer periods.

Danach bleibt der Brenner im Betrieb, auch während Zeiten, während derer er nicht funktionsgerecht eingesetzt wird, zum Erhitzen von Speisen etc. Dies bedingt andererseits fehlgeschlagene Kosten für Energie und Energieverschwendung bei entsprechender Umweltschädlichkeit, wobei der Brenner selbst in der Regel durch manuelle Betätigung eines Schalters entflammt wird.Thereafter, the burner remains in operation, even during times when it is not being used properly, for heating food, etc. This, on the other hand, causes unsuccessful costs for energy and energy wastage with corresponding environmental damage, the burner itself usually being operated manually by a switch is kindled.

Desweiteren weisen die herkömmlich verwandten Brennervorrichtungen einschließlich Herdschüssel und Rost keine abgeschlossene Einheit auf, als daß Speisereste und sonstige zur Erhitzung gebrachten Materialen bei Überströmen oder Verspritzen zum Beispiel aus einem Kochtopf in das Innere des Herdes gelangen, verbunden mit Verschmutzung, Hygienenachteilen und Beeinträchtigung der Funktionstüchtigkeit des Herdes insgesamt.Furthermore, the conventionally used burner devices, including the cooker bowl and grate, do not have a closed unit, so that food residues and other materials brought to heating in the event of overflow or splashing, for example, get into the interior of the cooker from a cooking pot, combined with contamination, Disadvantages of hygiene and impairment of the overall functioning of the cooker.

Der Erfindung liegt die Aufgabe zugrunde, eine Brennervorrichtung zu schaffen, die nur dann in Betrieb gesetzt wird, also entflammbar gestellt wird, soweit auch tatsächlich ein funktionsgerechter Einsatz des Brenners und damit des Herdes vorliegt, hier das Erhitzen von Kochtöpfen, Bratpfannen etc.The invention has for its object to provide a burner device which is only put into operation, that is to say made flammable, insofar as there is actually a functional use of the burner and thus of the cooker, here the heating of cooking pots, frying pans etc.

Desweiteren liegt der Erfindung die Aufgabe zugrunde, in Kombination mit der Selbstentflammbarkeit des Brenners eine abgeschlossene Brennervorrichtung, bestehend aus Herdschüssel, Brenner und Rost zu schaffen, die verhindert, daß Speisereste und sonstige, nicht verwertbare Stoffe, in das Innere des Herdes gelangen, mit den wie vor bezeichneten nicht gewünschten Wirkungen.Furthermore, the invention has for its object to provide, in combination with the self-flammability of the burner, a closed burner device consisting of a cooker bowl, burner and grate, which prevents food residues and other non-usable substances from getting into the interior of the cooker with the as previously described undesired effects.

Derzeit sind zwar selbstentflammbare Gasbrennervorrichtungen bekannt, sei es über Sensoren oder sonstige elektronische Einrichtungen gesteuert, die jedoch allesamt nicht gewerblich genutzt werden, bzw. genutzt werden können, in Ermangelung einer funktionsgerechten Brauchbarkeit. Insbesondere ist keine selbstentzündbare Brennvorrichtung bekannt, die aus einem geschlossenen System besteht, bei Meidung von Verunreinigungen des Herdes im Inneren, also herdseitig außerhalb der Herdschüssel und der Brennervorrichtung.Self-flammable gas burner devices are currently known, whether controlled by sensors or other electronic devices, but all of which are not or cannot be used commercially, in the absence of functional suitability. In particular, no self-igniting burning device is known which consists of a closed system, while avoiding contamination of the stove inside, ie outside the stove bowl and the burner device.

Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale der Ansprüche 1 bis 4 gelöst.The object is achieved by the characterizing features of claims 1 to 4.

Die Erfindung beruht auf der Überlegung, durch eine mechanische Vorrichtung das Gewicht der auf den Brennerrost zu verbringenden Gefäße (Kochtopf, Bratpfanne) zu nutzen, in dem bei Aufsetzen dieses Gefäßes auf den Brennerrost (12) gleichzeitig ein mit Kugelkopf versehener Stift (7) ca. 1 cm nach unten gedrückt wird, und dadurch ein Elektroschalter (8) betätigt wird, der wiederum durch elektrischen Impuls ein Magnetventil (9) auslöst.The invention is based on the idea of using a mechanical device to use the weight of the vessels to be placed on the burner grate (saucepan, frying pan), in which, when this vessel is placed on the burner grate (12), a pin (7) provided with a ball head approx Is pressed down 1 cm, thereby actuating an electrical switch (8) is, which in turn triggers a solenoid valve (9) by electrical impulse.

Die Brennervorrichtung selbst und der Kugelkopf mit Stift (7) ist auf und an der Herdschüssel so angebracht (6), daß Speisenreste und sonstige Flüssigkeiten und Materialien nicht in das Innere des Herdes gelangen können.The burner device itself and the ball head with pin (7) is attached to and on the cooker bowl (6) so that food residues and other liquids and materials cannot get inside the cooker.

Danach wird die Brennervorrichtung zu Beginn eines funktionsentsprechenden Vorganges (Kochen, Braten etc.) einmal durch den Hauptschalter (10) eingeschaltet bei entsprechender Gasdosierung (starke Flamme, weniger starke Flamme). Durch das Betätigen des Hauptschalters (10) wird zwar die Zündflamme (4) entflammbar gestellt, jedoch nicht der Hauptbrenner (1), weil die Gaszufuhr zwischen Hauptschalter und Gasbrenner durch den wie vor beschriebenen Magnetschalter (9) unterbrochen ist.
Erst wenn sich das Magnetventil (9) öffnet, strömt Gas in den Brenner (1), wobei sich dieses Gas dann durch die Zündflamme (4) entzündet und der Brenner betriebsbereit ist.Then the burner device is switched on once at the beginning of a function-appropriate process (cooking, roasting etc.) by the main switch (10) with appropriate gas metering (strong flame, less strong flame). By actuating the main switch (10) the pilot light (4) is set flammable, but not the main burner (1) because the gas supply between the main switch and the gas burner is interrupted by the magnetic switch (9) as described above.
Only when the solenoid valve (9) opens does gas flow into the burner (1), which gas is then ignited by the pilot flame (4) and the burner is ready for operation.

Danach ist der Brenner (1) nur dann in Betrieb, wenn ein Gefäß auf dem Brennerrost (12) steht, welches den Kugelstift (7) nach unten drückt, dadurch der Elektroschalter (8) ausgelöst wird und sich dadurch bedingt, das Magnetventil (9) öffnet. Andererseits erlischt der Brenner ohne weitere manuelle Betätigung, in dem das zuvor aufgebrachte Gefäß von dem Brennerrost wieder entfernt wird und sonach der Kugelkopf mit Stift (7) entlastet wird und dadurch wiederum der Elektroschalter (8) betätigt wird, bei gleichzeitigem Schließen des Magnetventiles (9) und Unterbrechung der Gaszufuhr.The burner (1) is then only in operation when there is a vessel on the burner grate (12) that presses the ball pin (7) down, which triggers the electrical switch (8) and causes the solenoid valve (9 ) opens. On the other hand, the burner goes out without any further manual actuation, in which the previously applied vessel is removed from the burner grate and the ball head is then relieved with a pin (7) and the electrical switch (8) is actuated again, while the solenoid valve (9 ) and interruption of the gas supply.

Der Elektroschalter (8), auf dem der Stift mit Kugelkopf (7) manuell einwirkt, ist mit einer Feder ausgestattet, die den Kugelkopf mit Stift (7) nach Entfernen des Gefäßes vom Brennerrost wieder nach oben drückt und gleichzeitig den Elektrokontakt dahingehend auslöst, als daß sich das Magnetventil (9) schließt.The electrical switch (8), on which the pin with ball head (7) acts manually, is equipped with a spring that presses the ball head with pin (7) back up after removing the vessel from the burner grate and at the same time triggers the electrical contact in such a way that the solenoid valve (9) closes.
