Abstract: A bladed wheel of a blower device has a main plate, a side plate and multiple fan blades between the main plate and the side plate. A fan casing of the blower device has a bell mouth portion and a guide wall portion, which extends in a radial-outward direction from an axial rear-side end of the bell mouth portion to an outer periphery of the side plate. An air reflecting space is formed in the fan casing at a radial-outside position of the guide wall portion and at an axial front-side position of the fan casing between an axial rear-side end of the guide wall portion and an axial front-end wall portion of the fan casing. Air blown out from the bladed wheel flows through an air blow-out passage, wherein sound wave of the air from the bladed wheel and sound wave of the air from the air reflecting space interfere with each other so that noise is decreased.

Abstract: A centrifugal blower includes a centrifugal fan and a case that houses the centrifugal fan. A blade of the centrifugal fan has an intake side edge portion extending from a shroud inward in a radial direction. The intake side edge portion has a negative pressure side inclined portion inclined to a negative pressure surface side of the blade with respect to an axial direction. The negative pressure side inclined portion has an inclination length in the axial direction, and the inclination length is larger in a reverse flow portion of the intake side edge portion close to the shroud than in a radially innermost portion of the intake side edge portion located at an innermost side in the radial 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: A centrifugal blower includes: a centrifugal fan having plural blades arranged around a fan axis and a separation plate to blow out air in a radial direction after being sucked from one side in an axial direction; a fan casing housing the centrifugal fan; a partition plate that defines a first air passage and a second air passage arranged on the other side of the first air passage in the axial direction; and a separation cylinder arranged inside the plural blades in the radial direction. The separation cylinder expands in the radial direction as extending toward the other side in the axial direction, and is shaped to extend outward in the radial direction obliquely to the axial direction at the other end position of the separation cylinder positioned at the other end in the axial direction.

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.

The partition cylinder portion partitions air drawn into spaces between the first blades from air drawn into spaces between the second blades. The separation panel has a plate shape extending in the radial direction. The inward extending part is located inside, in the radial direction, both connected ends of the first blades and connected ends of the second blades which are joined to the separation panel.

Abstract: A centrifugal blower includes a centrifugal fan and a partition cylinder portion. The centrifugal fan includes first blades and second blades arranged about a fan central axis. The partition cylinder portion has a cylindrical shape extending in an axial direction. A diameter of the partition cylinder portion expands in the axial direction. The partition cylinder portion is located inside the second blades in the radial direction. The partition cylinder portion partitions, on an airflow upstream side of the first blades and the second blades, air drawn into spaces between the first blades from air drawn into spaces between the second blades. A length of each first blade in the radial direction is larger than a length of each second blade in the radial direction.

Abstract: The air conditioner for a vehicle has a centrifugal fan and a housing. The centrifugal fan has a fan suction port and a rotary shaft and rotates centering on a rotational axis of the rotary shaft. The housing has a fan housing chamber, an introduction passage, and a wall. The fan housing chamber houses the centrifugal fan. The introduction passage guides air, which flows from an outside of the housing into the housing, to flow toward the centrifugal fan in a first direction intersecting with the rotational axis. The wall partitions the fan housing chamber and the introduction passage from each other and has an opening that faces the fan suction port. The wall has a rim defining the opening and being provided with an annular protruding portion. The annular protruding portion protrudes from the wall toward the introduction passage and covers the opening.
