Abstract

PURPOSE: To prevent whipping sounds to make low noise operation possible by sending wind by rotating blowing rotary body which is formed by laminating multi number of annular plates with appropriate spaces in between.
CONSTITUTION: Rotary body 5 which is formed by laminating multi number of annular plates 6 with suction openings at the center parts and with appropriate spaces in between and motor 3 to ratate the rotary body 5 are equipped. When the rotary body 5 is rotated, layer of air in the space 14 which contacts annular plate 6 is rotated with annular plate 6 by the frictional force, and then, the rotation of the layer of air is conveyed to the whole air in the space 14 by the rescosity. Therefore, wind blows along annular plate 6 and no whipping noise is generated. Also, by setting the ratio of diameters of suction openings 7 to be 0.5W0.9, highly efficient operation can be possible.
