Abstract

At least one rotatable sensor, e.g. an infrared emitting diode (3,22) with a defined directional diagram, detects a person, animal or object and opens a valve to an easily ignitable gas reservoir (8) if reflections are detected. The gas moves an inertial mass (10) that impacts a piezoelement (12) to cause an ignition spark. The ignited gas ignites a light oil wick (17) that burns until reflections are absent. An Independent claim is also included for a device for producing and quenching an open flame upon detection of a person or persons.

Description

Eine offene Flamme vermittelt immer das Gefühl der Geborgenheit und der besonderen Atmosphäre.An open flame always gives the feeling of security and comfort special atmosphere.

Der Sinn der vorliegenden Anmeldung besteht darin, sowohl im Gastronomiebereich als auch im häuslichen Umfeld eben diese Atmosphäre zu schaffen, aber auf besondere Art und Weise:
Nach Aktivieren der Vorrichtung kann im Gastronomiebereich jeder Tisch mit einer "offenen Flamme" ausgestattet werden, die allerdings nur dann zündet, wenn im Richtdiagramm durch einen Gast oder durch Bedienpersonal Reflexion eintritt.The purpose of the present application is to create this atmosphere in the catering sector as well as in the home environment, but in a special way:
After activating the device, each table in the catering area can be equipped with an "open flame", which, however, only ignites when reflection is made in the directional diagram by a guest or by operating personnel.

Gleichzeitig ist gewährleistet, daß die Flamme verlöscht, wenn der Tisch nicht mehr besetzt ist.At the same time it is ensured that the flame goes out when the table is no longer is busy.

Sowohl für die Gastronomie als auch für den häuslichen Gebrauch erhöht sich damit neben dem erstaunlichen Effekt die Sicherheit vor Brand.This increases both for gastronomy and for domestic use in addition to the amazing effect, security against fire.

Die Vorrichtung arbeitet in der vorgestellten Variante mit einem Piezokristall, der das Ende eines flexiblen Schlauchsegmentes bildet und der durch ein äußerst leicht entflammbares Gas durchströmt wird und eine träge Masse, bevorzugt gegen einen leichten Federmechanismus mit sich reißt. Damit wird das optimale Piezoelement schnell komprimiert die sehr nahe gegeneinander liegenden positionierten Elektroden bilden eine Funkenstrecke, die zunächst eine Zündflamme, unsichtbar im Gehäuse, erzeugen und gleichzeitig mit dieser Zündflamme die eigentliche Leuchtölflamme über einen Docht entfachen. Ventil- und Steuermechanismen spielen eine simple Ausführungsvariante. Daß damit eine Unzahl anderer Anwendungsmöglichkeiten geschaffen ist, versteht sich von selbst.In the variant presented, the device works with a piezo crystal, which End of a flexible hose segment forms and by an extremely light flammable gas flows through and an inert mass, preferably against one light spring mechanism tears with it. This is the optimal piezo element quickly compresses the electrodes positioned very close to each other form a spark gap, which is initially an ignition flame, invisible in the housing, generate and at the same time with this pilot light the actual light oil flame kindle over a wick. Valve and control mechanisms play a simple one Embodiment. That means a myriad of other uses created, goes without saying.

Die Erfindung wird nun anhand der Ansprüche 1-20 und der Fig. 1 und 1' näher erläutert. The invention will now be explained in more detail with reference to claims 1-20 and FIGS. 1 and 1 '.

Dabei zeigt Fig. 1 zeigt in schematisierter Darstellung eine Draufblick auf die Gesamtvorrichtung.Here, FIG. 1 shows is a schematic representation a plan view of the overall apparatus.

Als wesentlichstes Element erkennen wir Antrieb (hier vier IRED's (3,22) und IC (23). Daneben die beiden Reservoirs (8) für Zündgas (4) und (16) für Leuchtöl (5). Schlauchsegment (9), beginnend mit dem elektronisch verstärkten (19) Ventil (21') beinhaltet eine träge Masse (10) und bevorzugt eine leichtgängige Feder (23), die bei geöffnetem Ventil (21') die träge Masse (10) nicht hindert, gegen Piezoelement (12) zu schlagen und an den optimal angeordneten Elektroden (13) eine Zündflamme (15) zu entflammen, die wiederum geeignet ist, Docht (17) bei geöffnetem Ventil (21, 19) zu entzünden, der (17) durch Kapillarwirkung ständig aus Ölreservoir (16) gespeist wird.The most important element we see is the drive (here four IREDs ( 3 , 22 ) and IC ( 23 ). In addition, the two reservoirs ( 8 ) for ignition gas ( 4 ) and ( 16 ) for light oil ( 5 ). Hose segment ( 9 ), starting with the electronically amplified ( 19 ) valve ( 21 ') contains an inertial mass ( 10 ) and preferably a smooth-running spring ( 23 ), which does not prevent the inertial mass ( 10 ) against the piezo element ( 12 ) when the valve ( 21 ') is open beat and ignite a pilot flame ( 15 ) on the optimally arranged electrodes ( 13 ), which in turn is suitable for igniting wick ( 17 ) when the valve ( 21 , 19 ) is open, which ( 17 ) is constantly released from the oil reservoir ( 16 ) by capillary action is fed.

Besonders bemerkenswert nach Hauptanspruch (1) ist die Tatsache, daß die Information der IRED (3), d. h. bevorzugt die Reflexion (22) beim Eintauchen ins Richtdiagramm der entsprechenden IRED (3) mit Vorwiderstand und Stromversorgung (6) dem IC (23) zur Steuerung der Ventile (21, 21') zugeleitet werden. Die Ventile (24) und (25) dienen dazu, die entsprechenden Reservoirs wieder aufzufüllen.Particularly noteworthy according to the main claim ( 1 ) is the fact that the information of the IRED ( 3 ), ie preferably the reflection ( 22 ) when immersed in the directional diagram of the corresponding IRED ( 3 ) with series resistor and power supply ( 6 ) for the IC ( 23 ) Control of the valves ( 21 , 21 ') are fed. The valves ( 24 ) and ( 25 ) serve to refill the corresponding reservoirs.

Die Gesamtanordnung ist so konzipiert, daß die Stromversorgung (6) als mindestens eine Batterie und/oder Akkumulator ausgelegt ist.The overall arrangement is designed such that the power supply ( 6 ) is designed as at least one battery and / or accumulator.

Es ist erforderlich, den Stromverbrauch der Spulen für (21, 21') durch Verstärker (19) so gering wie möglich zu gestalten, ebenso, wie es notwendig ist, einen Hauptschalter (26) zu integrieren und die Restkapazität von Batterie und/oder Akkumulator (6) anzuzeigen.It is necessary to minimize the current consumption of the coils for ( 21 , 21 ') by amplifiers ( 19 ), as well as it is necessary to integrate a main switch ( 26 ) and the remaining capacity of the battery and / or accumulator ( 6 ) display.

Mit der IRED (3) wird ein Richtdiagramm erzeugt, das beim Eindringen Reflexion erzeugt, die wiederum über eine Photodiode und einen bevorzugten Transistor als Signal gewertet wird, womit IC (23) das Ventil (21') von Kompartiment (8) steuert. The IRED ( 3 ) generates a directional diagram that generates reflection when penetrating, which in turn is evaluated as a signal via a photodiode and a preferred transistor, with which IC ( 23 ) controls the valve ( 21 ') of compartment ( 8 ).

Die Vorrichtung muß weiterhin so designet werden, daß mit den IRED's (3, 22) zirkulär der Raum abgetastet wird und die Ventile (21, 21') bei fehlender Reflexion über einen bestimmten Zeitraum geeignet sind, gesperrt zu werden oder zu bleiben, womit gewährleistet ist, daß die offene Flamme unbeabsichtigt länger als notwendig brennt.The device must also be designed in such a way that the space is scanned in a circular manner with the IREDs ( 3 , 22 ) and the valves ( 21 , 21 ') are suitable for being blocked or remaining over a certain period of time in the absence of reflection, which ensures is that the open flame accidentally burns longer than necessary.
