Description
DEUTSCHESGERMAN
Die Erfindung bezieht sich auf eine Sicherheitsvorrichtung an mit Funkenstrecken arbeitenden Zündvorrichtungen für den Brenner der Back- und Bratröhre von Gasherden, welche mit einem unabhängig von dem Gassteuerorgan des Brenners betätigbaren Organ ausgestattet ist, mit welchem die Funkenstrecke über einen Hochspanmu'ngserzeuger mit Strom beschickbar ist.The invention relates to a safety device on ignition devices operating with spark gaps for the burner of the oven and roasting tube of gas stoves, which with an independent of the Gas control member of the burner is equipped with an actuatable member with which the spark gap is over a high-voltage generator can be charged with electricity.
Bei derartigen Backöfen besteht die Gefahr, daß der Brennraum bereits mit Gas gefüllt, die Backofentür aber geschlossen ist, wenn der Magnetzünder betätigt wird. Hierdurch können explosionsartige Zündungen entstehen.In such ovens there is a risk that the combustion chamber, the oven door, is already filled with gas but is closed when the magneto is operated. This can cause explosive ignitions develop.
Um dies zu vermeiden, wird gemäß der Erfindung vorgeschlagen, in die Leitung zwischen Hochspannungserzeuger und Funkenstrecke einen elektrischen Schalter einzuschalten, dessen eines Kontaktstück feststeht und dessen anderes mit der Tür der Backuncl Bratröhre derart verbunden ist, daß die Beschickung der Funkenstrecke mit Strom nur bei geöffneter Tür ermöglicht ist.To avoid this, it is proposed according to the invention, in the line between high voltage generator and spark gap to switch on an electrical switch, one of which is a contact piece is fixed and the other is connected to the door of the baking oven in such a way that the loading the spark gap with electricity is only possible when the door is open.
Gemäß vorteilhaften Ausführungsformen des Gegenstands der Erfindung wird bei Verwendung einer magnetelektrischen Maschine als Hochspannungserzeuger, im folgenden mit Magnetzünder bezeichnet, der Schalter in den Primärstromkreis des Magnetzünders derart eingeschaltet, daß der Schalter den Primärstromkreis bei geschlossener Backofentür entweder unterbrochen oder kurzgeschlossen hält. Das Kurzschließen hat den Vorteil, daß nur eine isolierte Leitung vom Magnetzünder zur Funkenstrecke erforderlich ist und als Rückleitung die Metallteile des Backofens verwendbar sind. Gemäß einer anderen Ausführungsform ist der Schalter der Funkenstrecke parallel geschaltet und so gestaltet, daß er bei geschlossener Backofentür die Funkenstrecke kurzschließt. According to advantageous embodiments of the subject matter of the invention, when using a Magnetic electric machine as a high voltage generator, hereinafter referred to as magneto, the switch in the primary circuit of the magneto switched on such that the switch the Primary circuit is either interrupted or short-circuited when the oven door is closed. That Short-circuiting has the advantage that only an insulated line from the magneto to the spark gap is required and the metal parts of the oven can be used as the return line. According to another Embodiment, the switch of the spark gap is connected in parallel and designed so that it is closed when The oven door short-circuits the spark gap.
Als Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung ein mit einem Backofen ausgestatteter Gasherd mit Magnetzünder dargestellt. Es zeigtAs an exemplary embodiment of the subject matter of the invention, one equipped with an oven is shown in the drawing Gas stove shown with magneto. It shows
Fig. 1 den mit eingebautem Backofen ausgestatteten Gasherd in raumbildlicher Darstellung mit schematischer Andeutung der Zündanlage,Fig. 1 the gas stove equipped with a built-in oven in a three-dimensional representation with a schematic Indication of the ignition system,

Der dargestellte Gasherd hat vier Brennstellen 11, 12, 13 und 14 mit einem zentralen Zündbrenner 15, über dem zwei einander gegenüberstehende Zündelektroden 16 und 17 isoliert gegeneinander und gegen Masse angeordnet sind. Die Elektrode 17 ist an einen SicherheitsvorrichtungThe gas stove shown has four burners 11, 12, 13 and 14 with a central pilot burner 15, above which two opposing ignition electrodes 16 and 17 insulated from one another and from one another Mass are arranged.

Magnetzünder 30 angeschlossen. In Reihe zu der Funkenstrecke 16, 17 liegt eine zweite Funkenstrecke, die von einer Elektrode 18 und einem mit Masse verbundenen Metallteil 19 gebildet wird, dem die gegen Masse isoliert befestigte Elektrode 18 mit Abstand gegenübersteht. Die zweite Funkenstrecke ist im Backofen in der Nähe eines nicht dargestellten Brenners angeordnet. Die Backröhre ist durch eine Tür 20 verschließbar. An dieser Tür ist ein gebogener Hebel 21 befestigt, an dessen freiem Ende eine Nase 22 angebracht ist und eine Zugfeder 23 angreift, die bestrebt ist, die Backofentür in die Schließstellung zu ziehen (Fig. 3). In dieser Stellung liegt die Nase 22 auf einer Blattfeder 24 auf, die am Gehäuse des Herdes isoliert befestigt und mit der Elektrode 18 der Backofenzündstrecke über eine isolierte Leitung 25 verbunden ist. Durch diese Anordnung wird die zweite Funkenstrecke 18, 19 kurzgeschlossen.Magneto 30 connected. In series with the spark gap 16, 17 is a second spark gap, which is formed by an electrode 18 and a metal part 19 connected to ground, which the opposite Ground insulated attached electrode 18 faces at a distance. The second spark gap is in the oven arranged in the vicinity of a burner, not shown. The oven can be closed by a door 20. A curved lever 21 is attached to this door, and a nose 22 is attached to its free end and a tension spring 23 acts, which tries to pull the oven door into the closed position (Fig. 3). In this position, the nose 22 rests on a leaf spring 24 on the housing of the cooker Fastened in an insulated manner and connected to the electrode 18 of the oven ignition path via an insulated line 25 is. The second spark gap 18, 19 is short-circuited by this arrangement.
