Description
"Flsmmenkontrolleinrichtung bei gasb etriebenen Absorber-Kühlgeräten11 Die Erfindung bezieht sich auf eine Flammenkontrolleinrichtung bei gasbetriebenen Absorber-Kühlgeräten mit einem Thermoelement, das zur Steuerung eines die Gaszufuhr überwachenden Magnetventils dient. "Flame control device for gas-operated absorber cooling units11 The invention relates to a flame control device in gas-powered Absorber cooling devices with a thermocouple that is used to control the gas supply monitoring solenoid valve is used.
Bei gasbetriebenen Absorber-Kühlgeräten ist es für den Benutzer wichtig, die Gasflamme von der Bedienungsseite des Gerätes her überwachen zu können. Dies gilt insbesondere für die Inbetriebnahme solcher Geräte.In the case of gas-powered absorber cooling units, it is important for the user to to be able to monitor the gas flame from the operating side of the device. this applies in particular to the commissioning of such devices.
Es ist bekannt, die Überwachung mit Hilfe von Lichtleitstäben durchzuführen, die von der Brennerflamme zur Frontseite des Kühlgerätes geführt werden und so eine direkte Beobachtung der Flamme ermöglichen (DBGM 7 120 267). Bei dieser Kontrolleinrichtung kann durch die begrenzte länge des Lichtleitstabes und aus konstruktiven Gründen die Anzeige zumeist nicht an einer beliebigen Stelle des Eühlgerätes angeordnet werden.It is known to carry out the monitoring with the help of light guide rods, which are led from the burner flame to the front of the cooling device and such a enable direct observation of the flame (DBGM 7 120 267). With this control device can due to the limited length of the light guide rod and for design reasons the display is usually not arranged at any point on the Eühlgerätes will.
Ferner ist der lichtleitstab bruchempfindlich.Furthermore, the light guide rod is fragile.
Der Erfindung liegt die Aufgabe zugrunde, eine Flammenkontrolleinrichtung anzugeben, bei der eine vorteilhafte Anordnung der Anzeige, beispielsweise in der Randleiste oder im Dekorrahmen des Kühlgerätes, ermöglicht.wird.The invention is based on the object of a flame control device indicate in which an advantageous arrangement of the display, for example in the Edge strip or in the decorative frame of the refrigerator. Is made possible.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an das Thermoelement zusätzlich über einen Spannungsverstärker eine beim Brennen der Flamme leuchtende Anzeigelampe angeschlossen ist. Der Verstärker und die Anzeigelampe werden von einer Hilfsspannungsquelle, z.B. einer Batterie, versorgt.According to the invention, this object is achieved in that the thermocouple an additional one that lights up when the flame is burning via a voltage amplifier Indicator light is connected. The amplifier and indicator light are powered by one Auxiliary voltage source, e.g. a battery, is supplied.
Da die Anzeigelampe nur über eine Kabelverbindung angeschlossen ist, kann sie an beliebiger Stelle des Kühlgerätes, oder auch räumlich davon getrennt, angeordnet werden. Ein weiterer Vorteil liegt in der besseren Sichtbarkeit der Anzeige.Since the indicator lamp is only connected via a cable connection, it can be placed anywhere on the cooling unit, or also spatially separated from it, to be ordered. Another advantage is the better visibility of the display.
Die erfindungsgemäße Einrichtung kann bei allen gasbetriebenen Absorber-Kiihlgeräten mit Hilfsspannungsquelle bzw. Bordnetzanschluß im Kfz-Wohnwagen angewendet werden.The device according to the invention can be used with all gas-operated absorber cooling devices can be used with an auxiliary voltage source or on-board power supply in the caravan.
Bei jedem Gas-Absorber-Eühlgerät befindet sich ein Thermoelement zur Zündsicherung in der Gasflamme, dessen Thermostrom ein Magnetventil in der Gasarmatur betätigt. Die Elementspannung beträgt im Betriebsfall ca. 5mV. Diese Spannung ist für den Betrieb einer Anzeigelampe zu niedrig und muß deshalb auf eine Höhe von einigen Volt verstärkt werden. Als Verstärker kann vorteilhaft ein integrierter Operationsverstärker benutzt werden, der eine räumlich kleine Gestaltung der Verstärkerplatine ermöglicht. Als Anzeigelampe wird vorteilhaft eine Leuchtdiode (Gallium-Arsenid-Phosphor-Diode) verwendet, da diese leistungsmäßig am besten mit dem Operationsverstärker zusammengeschaltet werden kann.Each gas absorber cooling device has a thermocouple for Ignition safety device in the gas flame, the thermal flow of which is a solenoid valve in the gas valve actuated. The element voltage is approx. 5mV when in operation. This tension is too low for an indicator lamp to operate and must therefore be at a height of a few volts. An integrated amplifier can advantageously be used as an amplifier Operational amplifiers are used, which means that the amplifier board has a small design enables. A light-emitting diode (gallium-arsenide-phosphor-diode) is advantageously used as the indicator lamp. is used because it is best connected to the operational amplifier in terms of performance can be.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung als Blockschaltbild angegeben.An embodiment of the invention is shown in the drawing as a block diagram specified.
Ein Thermoelement 1 ist an den Eingang eines Operationsverstärkers 2 angeschlossen. Am Ausgang des Operationsverstärkers befindet sich eine Leuchtdiode 3.A thermocouple 1 is connected to the input of an operational amplifier 2 connected. There is a light-emitting diode at the output of the operational amplifier 3.
Sobald sich eine Gasflamme 4 im Absorber entzündet, gibt das Thermoelement eine Spannung ab, die vom Operationsverstärker verstärkt wird. Durch den verstärkten Ausgangsstrom wird die leuchtdiode angeregt. Ein Aufleuchten der Diode ist also gleichbedeutend mit dem Vorhandensein einer Gasflamme.As soon as a gas flame 4 ignites in the absorber, the thermocouple emits a voltage that is amplified by the operational amplifier. Through the reinforced Output current, the light emitting diode is excited. A lighting up of the diode is therefore equivalent to the presence of a gas flame.
