Abstract: A ventilation apparatus blows air into a vehicle compartment of a vehicle. The ventilation apparatus has a blower, a duct, a blowing outlet, guide vanes, and a turning mechanism. The blowing outlet is provided with the duct. The blowing outlet guides the air to flow along a lower surface of the duct. The guide vanes change a flow velocity component of the air in a lateral direction of the vehicle by guiding the air to flow along the guide vanes. The guide vanes are arranged in the duct on an upstream side of the blowing outlet and distanced from each other in the lateral direction. According to the above-described configuration, it is possible to provide a ventilation apparatus that can change a flow direction of air in the lateral direction of the vehicle while suppressing a pressure loss of air and a damage of the ventilation apparatus.

The separation cylinder is disposed inward of the blades in the radial direction of the centrifugal fan. The separation plate has an inner end surface extending from the one side to the other side in the axial direction at a position of an inner end in the radial direction. The separation cylinder has a separation cylinder end surface extending from the one side to the other side in the axial direction at a position of an end on the other side in the axial direction. A height of one of the separation cylinder end surface and the inner end surface in the axial direction is larger than a height of the other of the separation cylinder end surface and the inner end surface in the axial direction.

Abstract: A method for manufacturing a turbo fan unit includes a step for preparing multiple fan blades and an other-side side plate, and a step for connecting each of the multiple fan blades to the other-side side plate by a welding process. In the preparing step, one of the fan blade and the side plate is prepared, in which a connecting-surface forming portion having a connecting surface and a welding projection protruded from the connecting surface is formed. The connecting surface connects one of the fan blade and the side plate to the other one of the fan blade and the side plate. In the connecting step, the welding projection is melted down and the connecting surface is connected to an opposing surface, which is the surface of one of the fan blade and the side plate and which is opposing to the connecting surface.

Abstract: A fan main body member of a turbofan has multiple blades disposed around a fan axial center, a shroud ring which is coupled to each of the multiple blades, and a fan hub portion which is coupled to each of the multiple blades on a side opposite from the shroud ring. An other end side plate of the turbofan is fitted to the radially outer side of the fan hub portion and joined to an other side blade end portions of each of the multiple blades. In addition, an outer diameter of the fan hub portion is smaller than an inner diameter of the shroud ring. In addition, the multiple blades, the shroud ring, and the fan hub portion are integrally formed.

Abstract: The inside of a blower casing of a centrifugal blower includes a discharge airflow path, which extends outward in a radial direction of a rotating shaft, on an airflow downstream side from a trailing edge of each of blades of a centrifugal fan. The discharge airflow path includes an adjacent airflow path adjacent to the trailing edge of each blade. When the length in the axial direction of the blade at the trailing edge is assumed to be blade height, and when the length in the axial direction at the trailing edge of the centrifugal fan is assumed to be fan height, the length in the axial direction of the adjacent airflow path is equal to or larger than the blade height and equal to or smaller than the fan height.

Abstract: An air passage forming member includes an air passage inner wall surface that forms a wall surface of a connecting air passage connected to a cushion air passage. A blower device case has an air intake opening that is connected to the connecting air passage. A centrifugal fan is received in the inside of the blower device case. The air passage forming member is arranged such that at a downstream end of the connecting air passage, the air, which flows along the air passage inner wall surface in the connecting air passage, forms an air flow, which is directed in an axial direction of a fan central axis, or an air flow, which is directed toward an outer side in a radial direction of the fan central axis in comparison to the air flow that is directed in the axial direction.

Abstract: A blower includes a drive device, a shaft, a fan and a rotation limiter member. The fan includes: a main plate that has an axial hole which is securely press-fitted to the shaft; a shroud that is opposed to the main plate and has a suction inlet, which is formed at a center part of the shroud; and a plurality of blades that are placed between the shroud and the main plate and are arranged one after another around a central axis of the fan. The rotation limiter member is fixed to the shaft and the main plate. The main plate includes: a slope portion that is placed on an outer side of the rotation limiter member; and at least one planar surface part which is perpendicular to the central axis and is formed around the central axis at a part of the slope portion.

Abstract: In a cross section of a flow passage formed to conduct a flow of air from an inside/outside air box to an upper air passage of a scroll casing while the cross section of the flow passage is taken along an imaginary plane which includes an outer edge of an air guide plate and is parallel to a rotational axis of an impeller, a passage section, which is located on one radial side of a separation tube where a nose of the scroll casing is placed, is defined as a first opening section, and another passage section, which is located on an opposite radial side of the separation tube, which is opposite to the nose, is defined as a second opening section. A passage cross-sectional area of the second opening section is larger than a passage cross-sectional area of the first opening section.

Abstract: A centrifugal blower device includes a rotating shaft, a turbo fan unit and a casing. A shroud ring of the turbo fan unit and a cover portion of the casing form a gap between them. The gap includes a radial gap formed between the cover portion and the shroud ring in a radial direction and an axial gap formed between the cover portion and the shroud ring in an axial direction. The radial gap is located at a position outside of a shroud-side inner peripheral end in the radial direction. The axial gap is located at a position inside of the radial direction in the radial direction. A minimum gap dimension of the radial gap is smaller than a minimum gap dimension of the axial gap. A shortest distance between the shroud-side inner peripheral end and the cover portion is larger than the minimum gap dimension of the radial gap.
