Abstract

PURPOSE: To provide a simple and non-expensive device for producing a more irregular air speed and air direction in an electric fan provided with a fan grill at the front surface of a rotary vane by a method wherein a proper number of separate follower fan grills are arranged at the substantial intermediate radial location of the main fan grill.
CONSTITUTION: In an outer frame 1 provided with a suction port 2 and a blowing port 3 is arranged a vane wheel 4 which is driven by a motor 5. At the blowing port 3 of the outer frame 1 is rotatably arranged a main fan grill 6 through a shaft 7 and the inclined fan plates 8 are arranged side-by-side in a properly spaced apart relation. Follower fan grills 9 having a smaller diameter are rotatably arranged at the opposing position on a concentric circumference of the main fan grill 6 and then the air direction plate 11 is mounted adjacent thereof. Said fan grills 6, 9 are rotated under an air blown toward the blowing port 3 as the vane wheel 4 is rotated. The follower fan grills 9 are rotated in a larger diameter along with the main fan grill 6 and also rotated by themselves, thereby a strong and/or weak air power and an irregular air direction may be provided.
