Title:
BLADE FOR CROSS FLOW FAN AND CROSS FLOW FAN
Document Type and Number:
Japanese Patent JP2017166343
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a blade for a cross flow fan that makes a blowing condition and timing uneven along an axial direction to reduce the load acting on the blade at one time, thereby preventing vibration and noise, and to provide a cross flow fan.SOLUTION: The blade for a cross flow fan is extended along an axial direction of a cross flow fan and formed so that a position of the radially outer peripheral end thereof varies along the axial direction. Thus, a blowing condition and timing is made to be uneven in the axial direction and the load acting on the blade for a cross flow fan at one time is reduced to thereby prevent vibration and noise.SELECTED DRAWING: Figure 5
