Title:
BLOWER IMPELLER AND AIR CONDITIONER PROVIDED WITH THE BLOWER IMPELLER
Document Type and Number:
Japanese Patent JP3473549
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To sufficiently carry out an aerodynamic work even to a radial flowing-in of two suction flows of an axial flowing-in and a radial flowing-in and to sufficiently enhance a stationary pressure efficiency of a blower by making a shape of rotation track figure (meridian) of the impeller the most appropriate in a blower impeller.
SOLUTION: The blower impeller is provided with an impeller 1 driven by a motor. This impeller 1 has a plurality of blades 2 having a thin wing on an outer periphery of a hub 3 at a constant thickness. The blower impeller is constituted such that a front edge 6 of the impeller 2 becomes a convex curved line making a center point of the front edge 6 as a peak against a windward side on the rotation track figure of these blades 2.
