IPC: F04D29/28
Filed: 1992-12-25
Abstract: PURPOSE:To prevent the contraflow of air passing a clearance between the blade top of a multiblade blower and the inner wall of a case and also prevent the generation of contraflow and vortex of air flowing between blades so as to improve fan efficiency and reduce noise. CONSTITUTION:In the centrifugal multiblade fan 20 of a multiblade blower 6, plural blades 25 are formed annularly in the circumferential direction near the outer peripheral end of a bottom plate 24, and an annular shroud 26 is formed at the top of the blades 25. The shroud 26 is formed into approximately circular arc shape so that air from an air inlet 36 is changed in the flow direction from the axial direction of the fan to the radially outer direction. The bell mouth inner wall 31a and case inner wall of a case 22 are formed in such a way that a clearance to the shroud 26 is narrowed along the shape of the shroud 26. This narrow clearance is formed across the relatively long distance from the inner diameter side to the outer diameter side. The air coming out from between the blades 25 is thereby restrained from flowing back onto the inner diameter side from the outer diameter side through this clearance.
