<P>PROBLEM TO BE SOLVED: To provide a vortex flow blower of high pressure without increasing noise. <P>SOLUTION: The shape of a delivery side of a bulkhead 10 dividing a part between a delivery port 9 and a suction port 8 formed at a stationary channel 3 toward a rotary direction is made the same as that of a blade 4a, and the bulkhead 10 is positioned not to overlap the delivery port 9. This is due to the fact that pressure fluctuation at the intake side is larger than that at the delivery side and noise level is determined at the suction side. Consequently, the length of the stationary channel 3 in which a flow 11 turns can be extended, the number of turns of the flow 11 is increased, and the vortex flow blower of high pressure can be provided. <P>COPYRIGHT: (C)2009,JPO&INPIT |
