Abstract: A vehicle air-conditioning control system includes a controller that controls a blow outlet drive device and a plate member drive device based on a sensed result of a seat back state sensing device. When a reclined state of the seat back is sensed, the controller controls the blow outlet drive device and thereby places an air-flow direction change mechanism in a predetermined position to direct conditioning air, which is blown from the blow outlet, such that the conditioning air collides to a plate surface of a plate member. At this time, the controller also controls the plate member drive device to place the plate member in a predetermined position, so that the conditioning air, which collides to the plate surface of the plate member, reaches a specific part of an occupant who is on the seat having the seat back placed in the reclined state.

Abstract: A blower has a centrifugal multi-blade fan that has blades around a rotation axis and a casing that houses the centrifugal multi-blade fan. The centrifugal multi-blade fan satisfies a relation of d1/h1?5, in which d1 is a diameter of a part having the blades, and h1 is a height of the blades in an axial direction of the rotation axis. A part of the casing on one side in an axial direction of the centrifugal multi-blade fan has an air suction port. A part of the casing on the radial outer side of the centrifugal multi-blade fan has an air passage through which air blown from the centrifugal multi-blade fan flows. The casing has an enlargement portion that enlarges the air passage on at least one of the one side and an other side in the axial direction as the casing extends toward the radial outer side.
