Description
Elektrische Sicherheits- und Zündvorrichtung für Gasfeuerstellen Die Erfindung bezieht sich auf eine elektrische Sicherheits- und Zündvorrichtung für Gasfeuerstellen mit elektromagnetisch gesteuertem Ventil in. der Gaszufuhrleitung, wobei der Brenner nur dann mit Gas versorgt und gezündet werden kann, wenn durch einen Druckknopf ein Hilfsstromkreis geschlossen wird. Derartige Vorrichtungen sind bekannt. Das Kennzeichen der Erfindung liegt darin, daß die Magnetspule des elektromagnetisch geöffneten Ventils, der Glühdraht und der Druckknopf bzw. ein ihn überbrückender, parallel zu demselben liegender, durch einen Bimetallstreifen gesteuerter und bei Erwärmung durch die brennende Gasflamme geschlossener Schalter in Reihe liegen.Electric safety and ignition device for gas fires The Invention relates to an electrical safety and ignition device for Gas fireplaces with an electromagnetically controlled valve in the gas supply line, whereby the burner can only be supplied with gas and ignited when by an auxiliary circuit is closed with a push button. Such devices are known. The feature of the invention is that the solenoid of the electromagnetic open valve, the filament and the push button or a bypassing it, parallel to the same, controlled by a bimetal strip and enclosed Heating by the burning gas flame, closed switches are in series.
Bei den bisher bekannten Sicherheits- und Zündvorrichtungen für Gasfeuerstellen fehlt entweder die elektrische Zündung, oder der von der brennenden Flamme gesteuerte Wärmeschalter wird derart geschaltet, daß kein Schutz gegen Ausfließen von unverbrannten Gasen besteht für den Fall, daß bei unbeabsichtigtem Löschen der Flamme der Hilfsstromkreis unterbrochen ist.In the previously known safety and ignition devices for gas fires There is either no electrical ignition or that controlled by the burning flame Heat switch is switched in such a way that no protection against leakage of unburned Gas exists in the event that the auxiliary circuit is accidentally extinguished is interrupted.
Ein Ausführungsbeispiel der Erfindung ist in Fig. i der Zeichnung schematisch dargestellt. Fig. 2 zeigt das elektromagnetische Ventil im Schnitt. In Fig. i ist in die Gaszufuhrleitung, in welcher der von Hand betätigte Gashahn b liegt; a ist die Feuerstelle und n die Gasflamme. Außerdem liegt in der Gaszufuhrleitung das elektromagnetisch betätigte Ventil c, dessen Einzelheiten aus Fig. 2 ersichtlich sind. Dieses Ventil besteht aus dem Ventilgehäuse p, den Elektromagneten mit Spule r, dem Ventilkörper s und der Feder q. Bei nichterregtem. Magneten ist das Ventil geschlossen. Bei erregten .Magneten wird der N-entilkörper s angezogen und dadurch die Gaszufuhr zur Feuerstelle ca (Fig. i) in der Pfeilrichtung freigegeben. In der ähe der Feuerstelle ca liegt ein mit Lüftungsöffnungen t versehenes Rohr h, in welchem der Glühdraht o sowie der aus dem Bimetallstreifen e, l und den beiden Kontakten f und o bestehende Wärmeschalter angeordnet ist. Dieser Schalter ist bei gelöschter Feuerstelle a offen und schließt sich unter dem Einfluß der Flamme it mittels des Bimetallstreifens e. An embodiment of the invention is shown schematically in Fig. I of the drawing. Fig. 2 shows the electromagnetic valve in section. In Fig. I is in the gas supply line in which the manually operated gas tap b is; a is the fireplace and n is the gas flame. In addition, the electromagnetically actuated valve c, the details of which can be seen in FIG. 2, is located in the gas supply line. This valve consists of the valve housing p, the electromagnet with coil r, the valve body s and the spring q. With non-excited. Solenoid, the valve is closed. When the magnets are energized, the N-valve body s is attracted and the gas supply to the fireplace ca (Fig. I) is released in the direction of the arrow. In the vicinity of the fireplace ca is a tube h provided with ventilation openings t, in which the glow wire o and the heat switch consisting of the bimetallic strip e, l and the two contacts f and o are arranged. This switch is open when the fireplace a is extinguished and closes under the influence of the flame it by means of the bimetallic strip e.
Die Wirkung der Vorrichtung ist folgende: Durch Betätigen des Druckknopfes g fließt über K2, zti, 2c_, g1, g2, cl, c:., dl, d2, d3 nach Kl ein Strom, wodurch das Ventil c geöffnet und der Glühdraht d erhitzt wird, was zur Folge hat; daß die Gaszufuhr freigegeben und die Flamme an der Brennstelle a gezündet wird.The action of the device is as follows: By pressing the push button g flows via K2, zti, 2c_, g1, g2, cl, c:., dl, d2, d3 to Kl, whereby the valve c is opened and the filament d is heated, which has the consequence; that the The gas supply is released and the flame is ignited at the burning point a.
Sobald nun die Flamme brennt, so biegt sich der Bimetallstreifen e, l des Wärmeschalters durch, wobei die Kontakte o und f dieses Schalters geschlossen werden und wobei nun eine Reihenschaltung des Wärmeschalters, der Magnetspulen des Ventils c und des Glühdrahtes d über h2, sti, i, e, o, f, g2, c1, c2, d1, d2, d3 nach k1 entsteht.As soon as the flame is burning, the bimetallic strip e, l of the heat switch bends, whereby the contacts o and f of this switch are closed and a series connection of the heat switch, the solenoid coils of the valve c and the filament d via h2, sti, i, e, o, f, g2, c1, c2, d1, d2, d3 arise after k1.
Durch diese Schaltung wird völlige Sicherheit gegen Ausfließen von unverbranntem Gas bei unbeabsichtigtem Erlöschen der Flamme im Betriebe gewährt, und zwar auch dann, wenn die Zündung oder die Steuerung aus irgendeinem Grunde versagt oder sobald der Hilfsstromkreis unterbrochen ist. In allen diesen Betriebsfällen erfolgt augenblickliche selbsttätige Sperre der Gaszufuhr durch das Ventil c.This circuit provides complete security against leakage unburned gas in the event of unintentional extinguishing of the flame in the company, even if the ignition or control fails for any reason or as soon as the auxiliary circuit is interrupted. In all of these operating cases there is an instantaneous automatic shut-off of the gas supply through valve c.
