Air sending mechanism and image forming apparatus
View Patent ↗An air sending mechanism includes an air sending unit including a rotating shaft and a plurality of blade members provided on the rotating shaft, the air sending unit being configured to send air by producing a swirl flow swirling about the rotating shaft with rotation of the plurality of blade members; a wall member provided on a downstream side in an air sending direction with respect to the air sending unit in such a manner as to face the air sending unit; and a rectifying member provided between the air sending unit and the wall member and having at least one bend or curve provided as a result of the member being angled or curved such that the swirl flow produced by the air sending unit is guided in an intersecting direction that intersects the air sending direction.
1. An air sending mechanism comprising:
an air sending unit including a rotating shaft and a plurality of blade members provided on the rotating shaft, the air sending unit being configured to send air by producing a swirl flow swirling about the rotating shaft with rotation of the plurality of blade members;
a wall member provided on a downstream side in an air sending direction with respect to the air sending unit in such a manner as to face the air sending unit; and
a rectifying member provided between the air sending unit and the wall member and having at least one bend or curve provided as a result of the member being angled or curved such that the swirl flow produced by the air sending unit is guided in an intersecting direction that intersects the air sending direction,
wherein the rectifying member is angled or curved in an opposite direction that is opposite to a guiding direction in which the swirl flow is guided, the rectifying member guiding the swirl flow toward an air outlet provided on a downstream side in the opposite direction.
2. An air sending mechanism comprising:
an air sending unit including a rotating shaft and a plurality of blade members provided on the rotating shaft, the air sending unit being configured to send air by producing a swirl flow swirling about the rotating shaft with rotation of the plurality of blade members;
a wall member provided on a downstream side in an air sending direction with respect to the air sending unit in such a manner as to face the air sending unit; and
a rectifying member provided between the air sending unit and the wall member and having at least one bend or curve provided as a result of the member being angled or curved such that the swirl flow produced by the air sending unit is guided in an intersecting direction that intersects the air sending direction,
wherein the rectifying member has a plurality of spaces separated by at least one rectifying plate, and
wherein at least one pair of the plurality of spaces that are adjacent to each other communicate with each other via a hole provided in the rectifying plate.
