<p>PROBLEM TO BE SOLVED: To provide an automatic water discharge device having a power generating section, which can secure the power generation period for an optional time by keeping the revolving speed of a rotor in the power generating section, securing an electricity quantity by the power generation when the automatic water discharge device is used, and eliminating a water discharging action for only the power generation performed at the time other than the operation period. SOLUTION: The automatic water discharge device is provided with an opening/closing valve operated when part of a human body is detected by a detecting sensor and the power generating section generating power by using a stream. The rotating motion of the rotor by the stream in the power generating section is maintained more than before, thereby the power generating section can be rotated for an optional time even when the operation period is short, and a fixed power generation quantity can be secured.</p> |
