Document Type and Number:
Japanese Patent JPS6081507
Kind Code:
A
Abstract:
PURPOSE:To make a flow deviate at a wide angle without deteriorating a quantity of an air flow, by making a guide wall surface in a gradually expanding shape form on a part of a blade in case each of a plurality of pieces of blades is tilted respectively at a predetermined angle in an identical direction. CONSTITUTION:A plurality of pieces of blades 6 rotating centering around a shaft 5 provided at about right angles with a flow direction running along a path 2 is provided at an outlet part 4, and the blade 6 is arranged so that a part of the blade 6 forms a guide wall surface 7 in a gradually expanding shape to a flow direction running along the path 2 is case the blade 6 is rotated at a predetermined angle. In other words, as a shaft 5 is being arranged at an outlet part 4 in a gradually expanding shape, a flow can be made to deviate at a wide angle while a deterioration of a quantity of air is being controlled through adherence effect of the flow to a bent surface wall.
