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.

Abstract: An air conditioning device for a vehicle includes a seat air conditioning unit that blows out air from a front side of a seat and an interior air conditioning unit that blows out air whose temperature has been adjusted by a cooling heat exchanger and a heating heat exchanger toward the vehicle interior space. The air conditioning device for a vehicle includes a first duct member for guiding the air flowing between the cooling heat exchanger and the heating heat exchanger in the interior air conditioning unit to the seat air conditioning unit. The air conditioning device for a vehicle further includes a second duct member for guiding the air higher in temperature than the air flowing between the cooling heat exchanger and the heating heat exchanger to the seat air conditioning unit.

Abstract: An air-conditioning system comprising a vehicle air-conditioner which uses a target blowing-out temperature as the basis to control an air outlet temperature in a cabin and a seat air-conditioning unit which sucks recirculated air into a seat and controls at least the seat air-conditioning air flow per unit time so as to perform seat air-conditioning, wherein the air-conditioning system increases the seat air-conditioning air flow when detecting that the vehicle speed is a predetermined value or less, calculates a correction amount for the target blowing-out temperature considered neutral in warmness sense level for the increased seat air-conditioning air flow, and uses the correction amount as the basis to correct the target blowing-out temperature.

Abstract: A vehicle seat air-conditioning device includes a vehicle seat, an electric blower, and a plurality of ducts. The vehicle seat includes a plurality of regions. The electric blower includes a plurality of fans and one electric motor. The plurality of fans correspond to the plurality of regions, respectively. The electric blower drives the plurality of fans by the one electric motor to have blowing capacity corresponding to the plurality of regions respectively. Each of the plurality of ducts is provided between a corresponding one of the plurality of regions and a corresponding one of the plurality of fans. An air flow produced by each of the plurality of fans passes through a corresponding one of the plurality of ducts. The air flow passing through each of the plurality of ducts air-conditions or ventilates a corresponding one of the plurality of regions.

Abstract: A seat air-conditioner includes an inlet portion, a blower, and a door device. The inlet portion is disposed inside a seat and defines a first inlet and a second inlet. The blower is disposed inside the seat. The door device is configured to be moved to open the first inlet while closing the second inlet and to close the first inlet while opening the second inlet. The first inlet is arranged such that an air drawn into the seat through a passenger supporting portion of the seat is drawn into the blower through the first inlet. The second inlet is arranged such that an air drawn into the seat through a portion of the seat other than the passenger supporting portion is more likely to be drawn into the second inlet than into the first inlet.
