Title:
暖房器具の点火装置
Document Type and Number:
Japanese Patent JP5749141
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an ignition device of a heater which suppresses an inrush current at fuel ignition small and has a simple structure for ease of maintenance.SOLUTION: A blast pipe 26 is provided which blows out air coming through an air inlet 22 toward a wood pellet W through a blow-out opening 24. In addition, it is provided with ceramic heaters 28, 30 in which a resistance value R of each built-in resistor 28a, 30a has a positive temperature coefficient. It is further provided with a control device 32 which controls a voltage application operation to the ceramic heaters 28, 30 from a power supply 62. The ceramic heaters 28 and 30 are arranged inside the blast pipe 26 in series to a flow of air passing therethrough, and the resistors 28a, 30a are individually connected to output of a power supply 62. The practical heating operations of the resistors 28a, 30a, which are performed by continuously applying a commercial voltage Vac to the ceramic heaters 28, 30, are started by the control device 32 with a predetermined time lag in a way that the ceramic heater 28 closer to the blow-out opening 24 is started first.
