<P>PROBLEM TO BE SOLVED: To provide a centrifugal impeller in which, when designing a highly efficient centrifugal impeller, the length of a blade is set so that a plurality of blades cross a line that connects a rotation center of blades and the tip of the blades, and a basic shape of the centrifugal impeller is designed in a way that the blowing efficiency is maximized, and the highly efficient centrifugal impeller can be easily designed from three essential design dimensions. <P>SOLUTION: The centrifugal impeller includes: a main plate 2 connected to a motor shaft; a side plate 3 installed facing the main plate 2; and several blades 4 inclined in an anti-rotation direction installed at regular intervals in a circumferential direction between the main plate 2 and the side plate 3. The length of the blades 4 is set so that the plurality of blades 4 cross the line L that connects the rotation center O of the blades 4 and the tip T2 of the blades 4. <P>COPYRIGHT: (C)2013,JPO&INPIT |
