    Abstract: An air discharge device includes a duct that defines a flow passage through which a working air flow to be discharged passes, and a hole forming member defining an air discharge hole as an outlet of the working air flow. The hole forming member has a vortex generation structure configured to generate an auxiliary vortex having a vortex characteristic including a vortex rotation direction and a vortex axis direction. The vortex characteristic of the auxiliary vortex is different from that of a lateral vortex generated by the working air flow at a downstream side of the air discharge hole. The vortex generation structure is configured in the hole forming member so that the auxiliary vortex collides with the lateral vortex in a state where at least one of the vortex rotation direction and the vortex axial direction of the vortex characteristic is different from that of the lateral vortex.

    Abstract: A fluid discharge device is for discharging a fluid includes a duct defining a fluid flow passage and having an opening at a downstream end of the fluid flow passage. The fluid discharge device includes a grill portion disposed in the fluid flow passage to adjust a flow direction of the fluid blown from the opening. The grill portion includes at least an adjustment fin rotatably arranged in the fluid flow passage, and is provided with an auxiliary flow passage that guides a part of the fluid flowing through the fluid flow passage to the opening as an auxiliary flow. The auxiliary flow passage is configured together with the adjustment fin to adjust a flow direction of the auxiliary flow discharged from the auxiliary flow passage to be aligned with the flow direction of the fluid flowing through the fluid flow passage.

    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.
