PROBLEM TO BE SOLVED: To provide such an interlocking control function to a ventilating fan that can surely make the ventilating fan start operation when a gas cooking stove, etc., is ignited. SOLUTION: A motor 12 for driving a ventilating fan 11 can be operated at a high or low rotating speed when 'strong' or 'weak' is designated by operating a manual operation switch 15. When connectors 13 and 14 are removed and an interlocking adapter 10 is inserted between the connectors 13 and 14, a control circuit 20 is interposed between the connectors 13 and 14 and the motor 12 is operated at a low speed, and then, the fan 11 is driven in the 'weak' when the interlock signal received by means of a receiving unit 21 instructs the operation of the motor 12 even when the switch 15 does not designate the operation of the motor 12. When the ventilation is insufficient, the ventilation can be increased by operating the motor 12 at the high rotating speed by designating the 'strong' from the manual operation switch 15. |
