Abstract

PURPOSE: To reduce generation of noise by installing to a rotary grille a wind straightening blade member radiantly extended from the center of rotation and adding a deflector blade and by converting the wind produced by a fan into a wind which turns only one way like a search light.
CONSTITUTION: A rotary grille 9 is integrated with deflector blade members 11 and a wind straightening blade member 12. The wind straightening blade member 12 consists of a plurality of straightening blades radially extended from the rotation center of the rotary grille 9 up to a ringlike frame member 10. The wind straightening blades are provided with vertical and flat derofoils aligned in axial directions and equally spaced at the pitch of 30°. A spirally (shaped) and twisted wind produced by the rotation of the fan is accelerated by the wind straightening blade 12 and transformed into a straight wind moving in axial directions of the fan. Furthermore, the wind is converted into a wind which turns only one way like a search light by the deflector blades 11 and is dispersed, thereby reducing generation of noise.
