摘要： A cross-flow fan includes a plurality of fan blades. The fan blade has an inner edge portion arranged on an inner circumferential side and an outer edge portion arranged on an outer circumferential side. In the fan blade, a blade surface extending between the inner edge portion and the outer edge portion and constituted of a positive pressure surface and a negative pressure surface is formed. The fan blade has such a blade cross-sectional shape that a large-thickness portion at which a thickness between the positive pressure surface and the negative pressure surface is greatest is arranged closer to the inner edge portion. A recess recessed in the blade surface is formed at a position closer to the inner edge portion where the large-thickness portion is arranged, than to the outer edge portion.

摘要： A centrifugal fan includes a plurality of fan blades arranged spaced apart from each other in a circumferential direction. The fan blade has an inner edge portion disposed on an inner peripheral side and an outer edge portion disposed on an outer peripheral side. The fan blade has a blade surface including a pressure surface and a suction surface. When cut along a plane orthogonal to a rotation axis of the fan, the fan blade has a blade cross section having concave portions formed at the pressure surface and the suction surface. A plurality of fan blades include fan blades having blade cross sections of different shapes. With such a configuration, the fan has an excellent air-blowing capacity while preventing noise. A molding die for use in production of the fan and a fluid feeder including the fan are also provided.

摘要： An air conditioner includes: an air passage extending from a suction port to a blowout port, a heat exchanger at the upstream side of the air passage, a cross flow fan in the air passage on the downstream side of the heat exchanger, and an air passage wall provided in a downstream area of the cross flow fan to reach the blowout port. A restricting section that restricts an air passage sectional area is provided at a corner section of the side wall of the air passage wall. The restricting section has a shape by which the air passage sectional area has a rectangular cross section expanding from the upstream side to the downstream side and is restricted to reduce an enlargement ratio of the air passage sectional area. Further, the restricting section has a smooth restricting surface crossing the corner section of the cross section of the air passage.
