PURPOSE:To clean the wick by oil-less burning in a short time by a structure wherein a strong-weak changeover circuit is changed over to the strong side by turning ON the oil-less burning switch. CONSTITUTION:When oil-less burning is required a oil-less burning switch 16 is closed, a knob is turned and a switch 5 is operated. Accordingly, resistors 17, 23 send signals respectively to transistors 20, 19, and the blast is strong and the knob is fixed so that a blast fan motor 6 is fixed to the position ''strong'' and an electromagnet 4 is magnetized. Thus, strong combustion is always obtained at the oil-less burning time, cleaning by oil-less burning can be carried out in a short time and bad influence by exhaust gas is reduced so much. Accordingly, safety is improved remarkably. |
