| 摘要 |
The invention relates to a control device for a gas burner, which comprises an ignition device (1) with a spark electrode (8) for igniting gas, a gas valve (9) for gas supply to a burner (6), a flame-monitoring device (7) for keeping the gas valve open while the gas burns, and a switch (2) for supplying current to the ignition device (1). To make possible reignition of the gas, there has been connected in parallel with the switch (2), which supplies the current to the ignition device (1), a controllable switch (13) which, while the gas burns, closes, controlled by the flame-monitoring device (7), and consequently bridges the switch (2). The controllable switch (13) in question remains closed after extinction of the flame for a time determined by its control circuit and the cooling of the flame-monitoring device (7). Moreover, there has been connected to the control circuit of the controllable switch (13) a light-emitting diode (12) which serves as an indicator of the burning of the flame. <IMAGE> |
