Definitions
- the present invention relates to a gas stove, in particular a gas oven with at least one gas burner, a gas supply control arrangement associated therewith and a flame monitoring device also assigned to this.
- thermocouple assigned to a thermal fuse.
- the gas supply is immediately or after a very short delay interrupted in which the thermocouple cools and the thermal fuse no current provides more for the electrical holding magnet that otherwise keeps the gas supply line open.
- the object of the present invention is a Arrangement for gas stoves and gas ovens to provide flame monitoring for the user in a favorable way.
- An arrangement that meets these requirements in a gas stove or gas oven is, according to the invention, characterized in that an optical light indicator controlling from an existing flame on the gas burner and / or from the gas supply control valve influenceable evaluation arrangement is arranged.
- the evaluation circuit is expediently equipped in such a way that that the optical indicator driven by them when the gas supply control valve is turned on flashing and continuously with additional detection of a flame on the gas burner shines.
- the flashing light indicates that the gas supply knob is is switched on, but at the burner point no flame or a sufficiently strong flame is detected.
- the flashing therefore prompts the user to either ignite for to operate the gas burner and thereby start the flame or alternatively to reset the gas supply toggle to the rest position and thus finally the gas burner and definitely switch off.
- the glow of the optical light display shows indicates that when the gas supply control valve is turned on, the gas burner also functions properly is working.
- thermocouple namely for monitoring this thermocouple can be assigned to the flame for the thermal gas supply fuse can also be used as a signal generator for the evaluation circuit. It is also expedient to assign a threshold level to the evaluation circuit so that the evaluation circuit only responds from a certain predetermined detection temperature on the gas burner. This ensures that when a flame is displayed on the gas burner, this Flame is also such that the flame picture also appears stable.
- FIG. 1 shows the connection of a lamp 1 serving as an optical illuminated display to a Power supply U via two control paths 2 and 3.
- a switch in control path 2 4 which is controlled by a clock generator 5 with a clock frequency of approximately one Hertz becomes. If a contact acting on this 6 of the gas supply control valve at their Setting is closed, the clock 5 is activated and in that of the clock 5 supplied cycle, switch 4 is opened and closed. Is clocked accordingly the voltage U is supplied to the lamp 1 and this flashes.
- the gas burner assigned to the connected gas supply control valve and after sufficient The flame on the gas burner is formed by a thermocouple 7 detected and thereby a switch 9 in the current path 3 continuously via a threshold 8 closed.
- the switch 4 of the current path 2 is thus bridged and the indicator lamp 1 lights continuously.
