Abstract

PURPOSE: To obtain an electric fan with no noise and a high efficiency without the necessity of a net as a safety cover.
CONSTITUTION: An air absorbing cylinder 1 is so constituted as that an opening angle degree 2θ1 may be continued from an air absorbing port 5 of a funnel-shape of 120W180° degree up to a guide cylinder 2 analogue with a cylindrical shape fixed at the outer top end part of a blade 13 of a runner 3 by a smooth curved surface. And, guide blades 6 are set up by means of arranging them in a radial-shape in the interior part of the air absorbing cylinder 1, and the air absorbing cylinder 1 is fixed at the frame of a motor 4 by this guide blade 6. And the rear half parts of each guide blades are composed of flaps 8 for changing wind velocity combined by hinges 7 so as that the angle may be changed to the rotation direction of the runner 3 or to the rotation direction of the runner blade 13. By such means, there is no dangerous concaves and convexes on the outer circumferent part of the runner 3, and a desired performance is obtainable by a such constitution etc. of the line existence of the guide blade at the air absorbing side which is dangerous to absorb the hand.
