Abstract

The gas burner has a mechanically operated gas feed control, for automatically controlling the opening and closing of the gas supply to the gas burner (1) in response to the movement of the burner grid (12) due to the weight of a cooking pan being placed on it or lifted off. The movement of the burner grid operates an electric microswitch (6) controlling a magnetic valve (9) inserted in the gas feed line to the burner.

Description

Die Erfindung bezieht sich auf eine Brennervorrichtung, der im Oberbegriff des Anspruches näher bezeichneten Art.The invention relates to a burner device of the type specified in the preamble of the claim.

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, und soweit wie im Großküchenbereich in der Regel behördlich vorgeschrieben eine Zündflamme vorhanden ist. Danach verbleibt der Brenner auch in Betrieb, soweit während kürzerer, oder auch längerer Zeiten der Kochtopf, die Bratpfanne etc. vom Brennerrost genommen wird.In commercial canteen kitchens, gas stoves with large burner capacities are currently used in particular, in which the burner itself is usually ignited by manual operation of a switch, and as far as is officially stipulated by the authorities in the commercial kitchen area, as a rule, an ignition flame is available. The burner then remains in operation as long as the saucepan, frying pan etc. is removed from the burner grate during shorter or longer periods.

Danach bleibt der Brenner in 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.After that, the burner remains in operation, even during times when it is not being used properly, for heating food, etc. On the other hand, this causes failed costs for energy and energy wastage with corresponding environmental damage, the burner itself usually being operated manually by a switch is kindled.

Des weiteren weisen die herkömmlich verwandten Brennervorrichtungen einschließlich Herdschüssel und Rost keine abgeschlossene Einheit auf, als daß Speisereste und sonstige zur Erhitzung gebrachten Materialien bei Überströmen oder Verspritzen zum Beispiel aus einem Topf 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 get overflow or splash, for example, from a pot into the interior of the cooker, associated with pollution, hygiene disadvantages and impairment of the functioning of the stove as a whole.

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.

Des weiteren liegt der Erfindung die Aufgabe zugrunde, in Kombination mit der Selbstentflammbarkeit des Brenners ohne spezielle Betätigung des Hauptschalters durch manuelle Tätigkeit, 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 without special actuation of the main switch by manual activity, a closed burner device consisting of a cooker bowl, burner and grate, which prevents food residues and other non-usable substances , get inside the cooker, with the undesired effects described above.

Derzeit sind zwar selbstentflammbare Gasbrennervorrichtungen bekannt, sei es über Sensoren oder sonstige elektronische manuelle Einrichtungen gesteuert, die jedoch allesamt nicht gewerblich genutzt werden, bzw. genutzt werden können, in Ermangelung einer funktionsgerechten Brauchbarkeit, die die wie vor aufgezeigten Eigenschaften erfüllt. 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.At the moment, self-flammable gas burner devices are known, be they controlled by sensors or other electronic manual devices, but all of them cannot be used for commercial purposes, or cannot be used, in the absence of a functionally appropriate usability which fulfills the properties shown above. 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 3 gelöst.The object is achieved by the characterizing features of claims 1 to 3.

Die Erfindung beruht auf der Überlegung, durch eine mechanische Vorrichtung das Gewicht der auf den Brennerrost (12) zu verbringenden Gefäße (Kochtopf, Bratpfanne etc.) zu nutzen, in dem bei Aufsetzen dieses Gefäßes der Brennerrost (12) nach unten gedrückt wird und dadurch über ein Verbindungsteil (7) ein Elektroschalter (6) 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 (saucepan, frying pan, etc.) to be placed on the burner grate (12), in which the burner grate (12) is pressed down when this vessel is placed, and thereby An electrical switch (6) is actuated via a connecting part (7), which in turn triggers a solenoid valve (9) by means of an electrical pulse.

Die Brennervorrichtung selbst und der Rost (12) nebst dem Verbindungsteil (7) sind an der Herdschüssel (13) so angebracht, daß Speisenreste und sonstige Flüssigkeiten und Materialien nicht in das Innere des Herdes gelangen können.The burner device itself and the grate (12) together with the connecting part (7) are attached to the cooker bowl (13) in such a way that food residues and other liquids and materials cannot get inside the cooker.

Dadurch 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) durch den Zünder (5) entflammbar gestellt, jedoch nicht der Hauptbrenner (1), weil die Gaszufuhr (11) zwischen Hauptschalter und Gasbrenner durch das wie vor beschriebenen Magnetventil (9) unterbrochen ist.As a result, the burner device is switched on once by the main switch (10) at the start of a function-appropriate process (cooking, roasting, etc.) with appropriate gas metering (strong flame, less strong flame). When the main switch (10) is actuated, the pilot light (4) is made flammable by the igniter (5), but not the main burner (1) because the gas supply (11) between the main switch and the gas burner is provided by the solenoid valve (9 ) is interrupted.

Erst wenn sich das Magnetventil (9) öffnet, strömt Gas in den Brenner, wobei sich dieses Gas dann durch die Zündflamme (4) entzündet und der Brenner (1) betriebsbereit ist.Only when the solenoid valve (9) opens does gas flow into the burner, which gas is then ignited by the pilot flame (4) and the burner (1) is ready for operation.

Danach ist der Brenner (1) nur dann in Betrieb, wenn ein Gefäß auf dem Brennerrost steht, welches den Brennerrost (12) nebst dem Verbindungsstück (7) nach unten drückt, dadurch der Elektroschalter (6) ausgelöst wird und sich dadurch bedingt das Magnetventil öffnet. Andererseits erlischt der Brenner ohne weitere manuelle Betätigung, in dem das zuvor aufgebrachte Gefäß von dem Brennerrost (12) wieder entfernt wird und sonach der Brenner (1) und das Verbindungsteil (7) entlastet wird und dadurch bedingt wiederum der Elektroschalter (6) 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, which presses the burner grate (12) along with the connector (7) downwards, which triggers the electrical switch (6) and the solenoid valve is thereby caused opens. On the other hand, the burner goes out without further manual actuation, in which the previously applied vessel is removed from the burner grate (12) is removed again and then the burner (1) and the connecting part (7) are relieved and, as a result, the electric switch (6) is actuated, with the solenoid valve (9) being closed and the gas supply being interrupted at the same time.

Der Elektroschalter (6), auf den das Verbindungsstück (7) mechanisch einwirkt, ist mit einer Feder ausgestattet, die das Verbindungsstück (7) mit dem Rost (12) nach Entfernen des Gefäßes von dem Rost (12) wieder nach oben drückt und gleichzeitig den Elektrokontakt dahingehend auslöst, als daß sich das Magnetventil (9) schließt.The electrical switch (6), on which the connecting piece (7) acts mechanically, is equipped with a spring which presses the connecting piece (7) with the grate (12) back upwards after removing the vessel from the grate (12) and at the same time triggers the electrical contact so that the solenoid valve (9) closes.
