Abstract

PURPOSE: To obtain concentric winds, which velocity distribution differs, when a control blade is fixed, and to automatically change the strength of winds when the control blade is turned, by mounting the control blade to the front of an axial fan.
CONSTITUTION: A control blade 5 of wind velocity provided with a speed up blade 4 and a diffusion blade 10 is fixed to a protective net ornament 2, which is fastened to a protective net 1 at the blast passage side of an axial fan 9 by means of a screw 3, in a revolution-free shape by using a friction disc 6 with elasticity and a screw 7. With said speed up blade 4, length in the rotational direction is smaller than length in the blast direction, and it is mounted in an approximate radial shape centering around the center of revolution of the blade. As the diffusion blade 10, a plurality of blades,etc. are adopted which outward tilt with the advance in the blast direction in concentrical shapes. The control blades 5 are adequately combined or the control blade is singly used, and fixed or turned, thus forming the winds of the front of the axial fan 9, which velocity distribution has partial strength and weakness as natural winds, winds with breathes.
