PURPOSE:To effectively utilize a fan motor in the use for 'futon mat drying' and 'air cleaner' by operating a selecting switch for the perfect conduction of a heater and the fan motor when 'futon mat drying' is selected, while operating the selecting switch for restricting the electric conduction to the fan motor and reducing the number of revolution when 'air cleaner' is selected. CONSTITUTION:In the use as 'futon mat dryer', a selecting switch 5 is operated to 'futon mat drying' side, and a movable contact point 5a is connected to a fixed contact point 5b, and a timer knob 6 is operated to set operation time. According to this set, a heater 10 whose contact points 8b and 8c are connected with the common contact point 8a of a timer switch 8, timer motor 7, and a fan motor 9 are brought into electric conduction. While, in the case of the use as 'air cleaner', the selecting switch 5 is operated to an 'air cleaner' side, and the movable contact point 5a is connected with a fixed contact point 5c, and a voltage is applied to the fan motor 9 through a voltage reducing resistance 12. Since, in this case, the applied voltage for the fan motor 9 is restricted by the voltage reducing resistance 12, the fan is revolved at a low speed. |
