  • Patent number: 7956480
    Abstract: A faucet generator includes a case having water inflow and outflow ports and in which a water supply channel is formed, a rotor vane disposed inside the water supply channel, a magnet which is rotatable integrally with the rotor vane, a bearing which supports a force that the rotor vane receives from a water flow, a coil which produces an electromotive force by a rotation of the magnet, and a yoke having a base part surrounding the coil and a plurality of inductors spaced apart from each other and extending from the base part. The coil is spaced apart from the magnet in an axial direction of a rotation center axis of the magnet and is disposed to face the magnet, the magnet is magnetized on an outer circumferential face which intersects with a plane perpendicular to the rotation center axis, and the inductors are disposed outside the case to face the outer circumferential face of the magnet.

  • Patent number: 7919877
    Abstract: A faucet generator includes: a cylindrical body which has a water inflow port and a water outflow port, and in which a water supply channel is formed; a rotor vane which has rotor vane blades, and which is disposed in the water supply channel; a magnet which is rotatable integrally with the rotor vane; a coil in which an electromotive force is produced by rotation of the magnet; and a plurality of nozzles which eject water toward the rotor vane blades. The axial direction of the rotor vane is substantially parallel to the water supply channel. The nozzles change a direction of a water flow which is substantially parallel to the axial direction of the rotor vane, to eject water from a radially outward direction of the rotor vane blades to the rotor vane blades.
