Title: Impeller for blower
Inventor: KITANI MASARU
IPC: F04D29/30
Filed: 2001-05-17
Abstract: PROBLEM TO BE SOLVED: To secure the excellent quietness of an impeller for a blower by reducing the aerodynamic noise more efficiently. SOLUTION: The impeller has a speed increasing means X for increasing the speed of a surface flow A1 on the pressure face side near the rear edge 4b of a pressure face 4c of a blade 4. With the structure, the speed increase works on the surface flow A1 on the pressure face side near the rear edge 4b and the separation is inhibited, and therefore, the flow is stabilized. In addition, as the surface flow A1 on the pressure face side is released from the rear edge 4b to the rear to be confluent with a surface flow A2 on the negative pressure face side, stabilization of the flow of the surface flow A2 on the negative pressure face side is facilitated and the growth of a rear flow vortex A0 is inhibited, and therefore, the aerodynamic noise is effectively reduced.  Moreover, as the speed increasing means X consists of a groove 10, the speed of the surface flow A1 on the pressure face side is increased by an inner vortex A3 in the groove 10 and the growth of the rear flow vortex A0 is inhibited by the stabilization of the flow, and therefore, the aerodynamic noise caused by the rear flow vortex A0 is effectively reduced. As a result, the impeller for the blower with reduced aerodynamic noise and excellent in the quietness is provided.
