POWER GENERATOR FOR FAUCET

摘要

A power generator for a faucet comprising a central shaft substantially parallel with the water supply channel, a rotor blade having a plurality of rotor blade portions on the circumferential surface and provided in the water supply channel rotatably about the central shaft, a prewhirl stator blade provided on the upstream side of the rotor blade through a gap between them and having a plurality of stator blade portions for imparting a swirling flow to the rotor blade on the circumferential surface, a magnet rotatable integrally with the rotor blade, and a coil opposing the magnet, characterized in that the center of a rotor blade channel formed between the rotor blade portions is located radially outside of the center of a stator blade channel formed between the stator blade portions. Useless flow not imparting a torque to the rotor blade is suppressed and power generation efficiency can be enhanced.
