IMPELLER, BLOWER, AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2024/048769
Kind Code:
A1
Abstract:
Provided are an impeller and a blower capable of preventing a reduction in blowing efficiency and a reduction in heat exchange performance. The present invention comprises an annular side plate (32), a disc-shaped main plate (31), and a plurality of blades (40) disposed at predetermined intervals around an axis (X). The blade surface of each blade (40) has a blade thickness differing surface (43b), a main plate side surface (43a), and a side plate side surface (43c) in the blade width direction. The blade thickness differing surface (43b) differs in the angle of the blade surface with respect to the axis (X) in the blade width direction from the angles of the main plate side surface (43a) and the side plate side surface (43c) such that the blade thickness on the main plate (31) side relative to the blade thickness differing surface (43b) is larger than the blade thickness on the side plate (32) side relative to the blade thickness differing surface (43b).
