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 in Anspruch 1 näher bezeichneten Art.The invention relates to a Burner device as claimed in claim 1 specified type.

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 the commercial canteen area currently especially gas stoves with large Burner capacities used where the Burner itself usually by manual Actuation of a switch is inflamed, and as far as in the canteen kitchen area as a rule officially prescribed an ignition flame is available. The burner then remains also in operation, as long as shorter, or even longer times the saucepan, the Frying pan etc. is removed from the burner grate.

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 stays on, too during times when he wasn't is used for heating purposes of food etc. On the other hand, this requires failed costs for energy and Wasted energy with appropriate Harmful to the environment, the burner itself usually by manual operation of a Switch is ignited.

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 ones Burner devices including cooker bowl and rust not a closed unit than that leftovers and other food Heating materials taught Overflow or splash for example a pot get inside the stove, associated with pollution, hygiene disadvantages and impairment of 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 a To create burner device that only is put into operation, i.e. flammable is set, as far as actually Functional use of the burner and so that the stove is present, here the heating of saucepans, 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 the object in combination with the self-inflammability of the burner without any special Actuation of the main switch by manual Activity, a completed burner device, consisting of stove bowl, To create burners and rust that prevents that leftovers and other, not recyclable materials, inside the cooker do not arrive with the ones described above desired effects.

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.There are currently self-flammable gas burner devices known, be it about Sensors or other electronic manual Facilities controlled, but all of them not used for commercial purposes in the absence of one functional usability that the like fulfilled before shown properties. In particular, it is not self-igniting Burning device known from a closed system exists, with avoidance of Contaminations of the hearth inside, so cooker outside of the cooker bowl and the Burner device.

Auch die Anmeldungen EP A 0 636 841 und FR-A-2 662 236 erfüllen die vorgenannten Anforderungen nicht, weil das Schließen und Öffnen der Gaszufuhr nicht vom Kochgefäß her Berührungslos gesteuert wird und zum anderen Herdschüssel, Rost- und Brennereinheit kein geschlossenes System darstellen, bei Meidung von Verschmutzungen im Inneren des Herdes.The applications EP A 0 636 841 and FR-A-2 662 236 meet the aforementioned Requirements not because the closing and Do not open the gas supply from the cooking vessel Is controlled without contact and secondly Cooker bowl, grate and burner unit none represent a closed system with avoidance of dirt inside the cooker.

Die Aufgabe wird erfindungsgemäß durch die Merkmale der Ansprüche 1 und 2 gelöst.The object is achieved by the Features of claims 1 and 2 solved.

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 consideration a non-contact device a solenoid valve (9) to control, which in turn the Gas supply to the burner (1) opens and closes. This non-contact control device (7) reacts as soon as a vessel hits the Burner grate (12) is spent, and thereby triggers a pulse to the solenoid valve (9).

Die berührunglose Steuereinrichtung (7) ist so angebracht, daß Spiesereste und sonstige Flüssigkeiten und Materialien nicht in das Innere des Herdes gelangen können.The contactless control device (7) is like this attached that remnants of pebbles and other Liquids and materials not in that 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 Magnetschalter (7) unterbrochen ist.After that, the burner device will start a functionally appropriate process (Cooking, roasting etc.) once through the main switch (10) switched on when appropriate Gas metering (strong flame, less strong Flame). By operating the main switch (10) the pilot light (4) made flammable by the igniter (5), but not the main burner (1) because the Gas supply (11) between the main switch (10) and 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, gas flows into the burner pipe (2, 3), whereby this gas then through the pilot flame (4) ignited and the burner (1) ready for operation is.

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.Then the burner (1) is only in Operation when a vessel is on the burner grate (12) stands for the non-contact Control device (7) triggers, and thereby conditionally the solenoid valve (9) opens. On the other hand, the burner (1) goes out without further manual operation in which the previously applied vessel from the burner grate (12) is removed again and so that non-contact control device (7) Emits a pulse to the solenoid valve (9) at Shut off and shut off the gas supply.

Das berührungslose Steuerungsgerät (7) ist im weiteren bereich der Herdschüssel (13) so angeordnet, daß Speisereste und sonstige unerwünschte Materialien nicht in das Innere des Herdes gelangen können.The non-contact control device (7) is in the further area of the cooker bowl (13) see above arranged that leftovers and other unwanted materials not inside of the hearth.

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 non-contact control device (7) result from the state of the art different areas of application, be it photoelectronic Type or detection by electromagnetic fields etc. Crucial is however with this recognition that a non-contact detection and switching is present.
