Abstract

The gas burner has a contactless control device (7) for operating the magnetic valve (9) inserted in the gas feed line, in response to a pan being placed over the burner grid (12) or lifted from the burner grid. The contactless control device is positioned in the dished zone enclosing the burner and detects the presence of the pan by a photoelectric method or via electromagnetic field evaluation.

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 related burner devices including the cooker bowl and grate do not have a sealed unit other than that, for example, food scraps and other materials brought to be heated in the event of overflow or splashing a pot get inside the cooker, associated with pollution, hygiene disadvantages 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.

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 is based on the object, in combination with the self-flammability of the burner without special actuation of the main switch by manual activity, to create 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 berührungslose Vorrichtung ein Magnetventil (9) zu steuern, welches wiederum die Gaszufuhr zu dem Brenner (1) öffnet und schließt. Diese berührungslose Steuereinrichtung (7) reagiert, sobald ein Gefäß auf den Brennerrost (12) verbracht wird, und dadurch ein Impuls zu dem Magnetventil (9) auslöst.The invention is based on the idea of controlling a solenoid valve (9) by means of a contactless device, which in turn opens and closes the gas supply to the burner (1). This contactless control device (7) reacts as soon as a vessel is placed on the burner grate (12), thereby triggering a pulse to the solenoid valve (9).

Die berührungslose Steuereinrichtung (7) ist so angebracht, daß Speisenreste und sonstige Flüssigkeiten und Materialien nicht in das Innere des Herdes gelangen können.The non-contact control device (7) is attached 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 (starker Flamme, weniger starker 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 (10) und Gasbrenner (1) durch den wie vor beschriebenen Magnetschalter (7) unterbrochen 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 flame (4) is made flammable by the igniter (5), but not the main burner (1) because the gas supply (11) between the main switch (10) and the gas burner (1) through the as previously described magnetic switch (7) is interrupted.

Erst wenn sich das Magnetventil (7) öffnet, strömt Gas in die Brennerpfeife (2, 3), wobei sich dieses Gas dann durch die Zündflamme (4) entzündet und der Brenner (1) betriebsbereit ist.Only when the solenoid valve (7) opens does gas flow into the burner pipe (2, 3), this gas then igniting through the pilot light (4) and the burner (1) ready for operation.

Danach ist der Brenner (1) nur dann in Betrieb, wenn ein Gefäß auf dem Brennerrost (12) steht, welches das berührungslose Steuerungsgerät (7) auslöst, und dadurch bedingt das Magnetventil (9) öffnet. Andererseits erlischt der Brenner (1) ohne weitere manuelle Betätigung, in dem das zuvor aufgebrachte Gefäß von dem Brennerrost (12) wieder entfernt wird und sonach das berührungslose Steuerungsgerät (7) einen Impuls an das Magnetventil (9) abgibt, bei Schließen und Unterbrechung der Gaszufuhr.The burner (1) is then only in operation when there is a vessel on the burner grate (12) which triggers the non-contact control device (7) and thereby opens the solenoid valve (9). On the other hand, the burner (1) goes out without any further manual actuation, in which the previously applied vessel is removed from the burner grate (12) and the contactless control device (7) then emits a pulse to the solenoid valve (9) when closing and interrupting the Gas supply.

Das berührungslose Steuerungsgerät (7) ist im weiteren Bereich der Herdschüssel (13) so angeordnet, daß Speisenreste und sonstige unerwünschte Materialien nicht in das Innere des Herdes gelangen können.The non-contact control device (7) is arranged in the wider area of the cooker bowl (13) so that food residues and other undesirable materials cannot get inside the cooker.

Wegen des berührungslosen Steuerungsgerätes (7) ergeben sich nach dem Stand der Technik verschiedene Anwendungsbereiche, sei es photoelektronischer Art oder Erkennung durch elektromagnetische Felder etc. Entscheidend ist jedoch bei dieser Erkennung, daß eine berührungslose Erkennung und Schaltung vorliegt.Because of the contactless control device (7), there are various areas of application according to the prior art, be it photoelectronic or detection by electromagnetic fields, etc. However, what is decisive in this detection is that there is contactless detection and switching.
