REMOTE CONTROLLING PIEZO-OSCILLATOR FOR GAS APPLIANCE

摘要

PURPOSE:To safely and properly make a gas appliance to work in conjunction with a ventilating device by a structure wherein a transmission antenna is provided on the high-tension side of a piezoelectric ignition device so as to serve in combination as an oscillator to oscillate electromagnetic waves, which are generated when spark discharge occurs. CONSTITUTION:As for the titled remote controlling piezo-oscillator for gas appliance, a piezoelectric high tension generating device 12 is put into actuation by opening a main gas valve and operating an operating knob 16 so as to impact on a piezoelectric element 11 in order to generate high tension. The high tension is led to a discharge gap 13 in order to produce spark discharge. At the same time the spark discharge causes to ignite gas jetting from a pilot burner part 15 on one hand and to generate electromagnetic waves so as to oscillate from a transmission antenna 14 provided on the high tension side of the discharge gap 13. The electromagnetic waves radiated from the antenna 14 is received by a receiver provided in a ventilating device 17, resulting in driving a driving switch in order to actuate the ventilating device 17. Due to the constitution as described above, the ventilating device can be installed freely in a room regardless of the direction and distance to the gas appliance and the maintenance-free interlocking of the gas appliance with the ventilating device is realized.
