PURPOSE:To enable to stabilizedly control catalytic combustion, by controlling the opening of a gas burner by a bimetal for regulating the temperature. CONSTITUTION:When an operation switch 13 is pushed up to the ON direction, a linked lever 12 is released from being held, and a gas nozzle 2 is pushed up by the pushing force of springs 3, which starts injecting of gas. Being ignited, the gas passes through a catalyst 6 from a gas burner 15, and is converted to generate heat by catalytic reaction, heating a radiator plate 9. At this time, the top 15d of a gas burner 15 is contacted to a bimetal 8, while the bottom 15a is put on the gas nozzle 2. A slight change in the degree of curving corresponding to the change in the temperature in a bimetal 8 can be transmitted to the gas nozzle 2 through the gas burner 15. In such a manner, the opening of a gas burner 15 can accurately be controlled. |
