Abstract
Official abstract text for this publication.
A fan casing includes: an air duct communicating with an air inlet and outlet; a frame body forming an outer peripheral surface of the air duct; a hub portion forming an inner peripheral surface of the air duct on the outlet side; and a stator blade portion provided in the air duct, the stator blade portion coupling the frame body to the hub portion. The hub portion includes a cylindrical-shaped cylindrical portion and a tapered portion provided next to the cylindrical portion and provided in such a manner as to increase the width of the air duct toward the outlet. The stator blade portion couples the cylindrical portion to the frame body.
First claim
Opening claim text (preview).
What is claimed is: 1 . A fan casing comprising: an air duct communicating with an air inlet and outlet; a frame body forming an outer peripheral surface of the air duct; a hub portion forming an inner peripheral surface of the air duct on the outlet side; and a stator blade portion provided in the air duct, the stator blade portion coupling the frame body to the hub portion, wherein the hub portion includes a cylindrical-shaped cylindrical portion and a tapered portion provided next to the cylindrical portion and provided in such a manner as to increase the width of the air duct toward the outlet, and the stator blade portion couples the cylindrical portion to the frame body. 2 . The fan casing according to claim 1 , wherein the tapered portion is inclined toward a central axis of the cylindrical portion or has an arc shape. 3 . The fan casing according to claim 1 , wherein the stator blade portion extends toward the outlet beyond a coupled part between the stator blade portion and the cylindrical portion, and is placed around the tapered portion, spaced from the tapered portion. 4 . The fan casing according to claim 2 , wherein the stator blade portion extends toward the outlet beyond a coupled part between the stator blade portion d the cylindrical portion, and is placed around the tapered portion, spaced from the tapered portion. 5 . A fan apparatus comprising: the fan casing according to claim 1 ; a motor; and a rotor blade portion pivotally supported by the motor, and rotated by drive of the motor to blow air through the air duct. 6 . A fan apparatus comprising: the fan casing according to claim 2 ; a motor; and a rotor blade portion pivotally supported by the motor, and rotated by drive of the motor to blow air through the air duct. 7 . A fan apparatus comprising: the fan casing according to claim 3 ; a motor; and a rotor blade portion pivotally supported by the motor, and rotated by drive of the motor to blow air through the air duct. 8 . A fan apparatus comprising: the fan casing according to claim 4 ; a motor; and a rotor blade portion pivotally supported by the motor, and rotated by drive of the motor to blow air through the air duct.
