Ventilator

Abstract

Abstract PURPOSE:To use electricity in view of the energy saving, by operating a ventilator using a solar cell as power source when the sunlight is available, and on the other hand using an emergency rechargeable battery as power source in other case. CONSTITUTION:An electric contact 10 of an electromagnetic contact 11 is connected to an emergency rechargeable battery 8. The other electric contact 18 of the electromagnetic relay 11 can be changed to a solar cell 5 or the emergency rechargeable battery 8. When the sunlight strikes the solar cell 5, a voltage is induced therein, and at the same the resistance value of a CdS resistor 15 lowers to actuate an electric current actuation relay 16, an electromagnetic relay 11 is actuated by an electric contact 17, the electric contact 18 is actuated, and the voltage of the solar cell 5 is applied to a fan motor 6 so that the fan is operated. In the case wherein the sunlight is less such as in a case of night, the fan motor 6 is operated using the emergency rechargeable battery 8 as power source.
