PCT No. PCT/KR94/00176 Sec. 371 Date Aug. 7, 1996 Sec. 102(e) Date Aug. 7, 1996 PCT Filed Dec. 13, 1994 PCT Pub. No. WO95/16861 PCT Pub. Date Jun. 22, 1995The present invention relates to an electric fan employing three impellers which are so implemented as to receive the driving force of the motor and, more particularly, to an electric fan equipped with the second crank device and the convex surfaced driving bevel friction wheel and driven bevel friction wheel to swing the fan impeller shaft up-down repeatedly and right or left simultaneously, and to an electric fan that has the carrying handle or the carrying handle with the wheels for the convenience of moving, and also to an electric fan that can separate the upper body from the lower body to establish itself as a short up-right standing type, an attache-to-ceiling type, or an attach-to-wall type, and to an electric fan that can get rid of blowing reaction by a stabilizer and, thus, stabilize the swing movement of the fan impeller. |
