Abstract: A blower includes a fan that rotates about an axis center in an air conditioning case, and a casing that guides air blown from the fan. The casing has a peripheral wall that is located radially outward of the fan with the axis center as a center. The peripheral wall has first and second scroll inner wall surfaces that guide different kinds of air blown from the fan to different outlets. No half-lines starting from the axis center passes through both of the first and second scroll inner wall surfaces.

Abstract: A plurality of seating surface blowing ports is open at a seating surface of a seat. A first rear seat blowing port is provided on a rear side of the seat and opens toward a rear seat on the rear side of the seat. A single first duct is provided between the plurality of seating surface blowing ports, the first rear seat blowing port and the interior air conditioning unit, and guides the air conditioning wind from the interior air conditioning unit to the plurality of seating surface blowing ports and the first rear seat blowing port. The air conditioning wind that flows from the interior air conditioning unit through the first duct is blown out into a vehicle interior from the plurality of seating surface blowing ports and the first rear seat blowing port.

Abstract: An interior unit includes a discharge water passage communicating with a drainage port and having a first space portion in which water inside an air conditioning casing flows down from a guide opening portion, and an upward wall portion and a downward wall portion which constitute a partition wall separating between the discharge water passage and a second space portion adjacent to the discharge water passage and preventing the water falling in the discharge water passage from flowing into the second space portion. A prevention wall extending upward from a bottom wall portion in the second space portion is provided, and an upper end of the prevention wall is higher than a position of a fixation portion in which the first casing member and the second casing member are fixed with each other.

Abstract: A vehicle air-conditioning apparatus includes a casing that defines an air passage through which an air flows, and a blower that has a blower fan generating an airflow in the air passage. The vehicle air-conditioning apparatus includes an air-conditioning device that is provided in the air passage, and an air introduction member that introduces an air from a vehicle compartment. The vehicle air-conditioning apparatus further includes an aspirator that is located outside the casing and takes in the air flowing through the air passage as a first air, the aspirator drawing the air from the vehicle compartment as a second air through the air introduction member by using a flow of the first air. A cooling target mounted in the vehicle is cooled by a flow of the air drawn from the vehicle compartment by the aspirator through the air introduction member.

Abstract: A cooling device is applied to an in-vehicle equipment having a cooling unit which cools air, and cools an in-vehicle heat-emitting apparatus with the air cooled by the cooling unit. The cooling device includes: an adsorption unit including an adsorption material which adsorbs moisture; an adsorption case that defines a housing space in which the adsorption unit is disposed, the air cooled by the cooling unit passing through the adsorption case, the adsorption material adsorbing moisture from the air; and a cooling air outlet part that guides a dehumidification air, from which the moisture is adsorbed within the adsorption case, to a target space to be cooled where the heat-emitting apparatus is arranged.

Abstract: A humidification device includes: an adsorber having an adsorbent that adsorbs and desorbs moisture; an adsorption case that forms an accommodating space to accommodate the adsorber; a first introduction portion that introduces cooled air produced by a cooling portion into the adsorption case; a second introduction portion that introduces heated air produced by the heating portion into the adsorption case; and a humidification-side guiding portion that guides humidification air humidified by the moisture desorbed within the adsorption case, to the vehicle interior. The first introduction portion is connected to one of an upper surface portion and a side surface portion of the air-conditioning case, on an air-flow downstream side of the cooling portion in the air-conditioning case.

Abstract: A humidification device for a vehicle air conditioner includes an adsorber having an adsorbent, an adsorption case configured to provide an accommodating space that accommodates the adsorber and includes a moisture-adsorption space and a moisture-desorption space, a humidification-side guiding portion that guides humidification air humidified by using the moisture desorbed within the moisture-desorption space to a vehicle interior, a moving mechanism that moves at least a part of the adsorbent existing in the moisture-adsorption space of the adsorber to the moisture-desorption space while moving at least a part of the adsorbent existing in the moisture-desorption space of the adsorber to the moisture-adsorption space, and a desorption control unit that executes a desorption operation to desorb moisture adsorbed in the adsorbent when humidification of the vehicle interior is stopped.

The first introduction portion is connected to a bottom surface portion of the air-conditioning case on the air-flow downstream side of the cooling portion in the air-conditioning case.

Abstract: A synthetic resin skin material includes, on one side of a base material 12, an adhesive layer 14, a skin layer 16, and a surface processing layer 18 in this order from the base material 12, the adhesive layer 14 and the skin layer 16 containing a polyurethane urea resin having a number average molecular weight of from 35,000 to 100,000.

Abstract: An air conditioning unit has an air conditioning case, a blower, and a heat exchanger. The air conditioning case is arranged in a vehicle compartment on a rear side with respect to an instrument panel in a traveling direction of a vehicle and forms an air passage delivering air toward a specified area of the vehicle compartment. The blower has at least first and second impellers and a fan case housing the first and second impellers, and ventilates the air in the air conditioning case by drawing and blowing air, by using a rotation of the first and second impellers, through first and second suction ports formed in the fan case. The heat exchanger is arranged in the air conditioning case on an upstream side of the blower in an airflow direction and exchanges heat of the air. The blower draws air from the heat exchanger and blows the air to the specified area of the vehicle compartment.
