More Information
Summary:Blower case (8) provided in centrifugal blower (1) of the present invention has side wall (8c), suction port (8a), a discharge port, and flow channel (9). In flow channel (9), when impeller (3) is rotated by rotation action transmitted from motor (2), air sucked from suction port (8a) and passed through an inner peripheral side end and outer peripheral side end (3f) is guided to the discharge port along side wall (8c). A shape of a cross section of flow channel (9) including rotational axis (3c) is wider, toward an opposite side where the suction port is located relative to a side where suction port (8a) is located in a direction along axial center (3g) direction, in a second cross section located near the discharge port than in a first cross section located far from the discharge port in a direction in which impeller (3) rotates.
