Abstract

PURPOSE: To improve the efficiency of a volute fan, by setting the side surface of swirl inlet portion of each blade of an impeller, at a prescribed angle to a plane perpendicular to the axis of rotation.
CONSTITUTION: An impeller 2, which is rotated by an electric motor 1, is provided with blades 3. When the impeller 2 is rotated in the direction of an arrow 9 in the drawing by driving the motor 1, external air conducted from a suction port 6 into an air passage 5 becomes a swirl 13 flows onto the blade 3 at 12. The pressure of the air is made high as it flows toward a discharge port not shown in the drawing. The blade 3 is cut at 11 so that its side surface 11 extends at an angle as to a plane perpendicular to the axis of the rotation. For that reason, the flow of the swirl in the air passage 5 is made smooth. As a result, an impact loss is minimized and the efficiency of a fan is greatly improved.
