<P>PROBLEM TO BE SOLVED: To provide a funnel-mounted power generator preventing an increase in a gas exhaust pressure loss (exhaust resistance) without complicating a structure and performing wind power generation having excellent environmental adequacy with high power generation efficiency by using outside air outside of a funnel. <P>SOLUTION: This wind power generator S includes: a stator 4 having a plurality of power generating coils 12 arranged in the vicinity of the periphery of a hollow through portion 4a; a hollow annular rotor 6 having a plurality of power generating magnets 16 arranged in the vicinity of the outer peripheral circle 6a of the rotor, arranged in the hollow through portion 4a of the stator 4 and rotated with a direction along a gas exhausting direction as a rotating shaft X; and an outside air guide passage 10 guiding the outside air A from a gas exhausting path to the downstream position of the rotor 6. The rotor 6 has a plurality of blades 24 provided between the outer peripheral circle 6a and an inner peripheral circle 6b in order to convert wind power into the torque of the rotor 6, and also is configured not to substantially disturb gas exhaust on the inner side of the inner peripheral circle 6b. <P>COPYRIGHT: (C)2011,JPO&INPIT |
