PURPOSE:To permit the ventilation for a long period by driving a ventilating fan by using the electric power of a solar battery installed into a container and a storage battery mounted onto a car when an engine is in operation and utilizing only the electric power of the solar battery when the engine is in stop. CONSTITUTION:When an engine 1 is driven, a charging generator 2 is driven, and the generated ac voltage is converted to a proper dc voltage by a voltage adjustor 3, and used for charging a storage battery 4. When the engine 1 is in operation, a switch part 5 is automatically turned-ON, and the electric power of the storage battery 4 is supplied into a dc electric motor 10 through a voltage adjustor A, and a ventilating fan arranged in a container is driven. Since a solar battery 7 is arranged onto the outside wall of the container, and the electric power is always supplied into the dc electric motor 10 through the voltage adjustor A, the ventilating fan can be driven even if the engine 1 is in stop when the switch part 5 is turned-OFF. |
