Definitions
- the present invention has been made in view of the above points, and suppresses the generation and growth of a tip vortex in a portion of the outer periphery of the blade that is not surrounded by a bell mouth, thereby providing a tip vortex on the propeller fan blowing side.
- the purpose of the present invention is to reduce the noise (ie, driving noise) generated by the collision between the fan guard and the fan guard.
- a plurality of blades 13 having a thick wall shape represented by an airfoil blade are provided on an outer peripheral surface of a hap 14 serving as a rotation center.
- the axial height H 2 of the cylindrical portion 5 c is too small in comparison with the axial height H 0 of the outer peripheral portion P of the blade 1 3 (i.e., H 2 / H 0 to 0.25), the growth area of the tip vortex E (i.e., the portion of the outer periphery P of the blade 3 that is not surrounded by the bell mouth cylindrical portion 5c) becomes too large.
- the effect of suppressing the growth of the tip vortex E by the cylindrical portion 5 c becomes insufficient, so that the interference sound between the tip vortex E and the fan guard 6 increases, and the axial height H 2 of the cylindrical portion 5 c Is the axial height H at the outer peripheral portion P of the blade 13.
- the start position of the arc of the blow-side arc portion 5b of the bell mouth 5 is set at the rear edge B of each of the blades 13.
- the distance between the trailing edge B of the blade 3 and the fan guard 6 is equal to the radius corresponding to the radius of the blow-side arc portion 5b of the bell mouth 5, so that the blowing wind speed is reduced and the blade 3
- the airflow W blown out from the trailing edge B of the bell mouth 5 is smoothly expanded outward without peeling off from the blow-side arc 5b of the bell mouth 5, and does not disturb before reaching the fan guard 6.
- the interference sound with the fan guard 6 can be reduced.
