    摘要： In a centrifugal type blower unit, a diameter of an air suction port is set to be larger than a minimum inner diameter of a centrifugal fan, and a slanting portion is formed in each blade of the centrifugal fan at a side of the air suction port so that an inner radius dimension of the centrifugal fan is increased toward the air suction port. Therefore, it can prevent sub-flow air which is sucked into the centrifugal fan from an end side of the blades in an axial direction from interfering with main-flow air which is sucked into the centrifugal fan from an inner radius side of the blades. Thus, the blower unit can reduce second noise generated therefrom without greatly reducing air-blowing capacity.

    摘要翻译： 在离心式鼓风机单元中，空气吸入口的直径设定为大于离心式风扇的最小内径，并且在空气吸入口侧的离心式风扇的每个叶片中形成有倾斜部 使得离心风扇的内径尺寸朝向空气吸入口增加。 因此，可以防止从叶片的端部侧沿轴向吸入离心风扇的副流动空气与从叶片的内径侧吸入离心式风扇的主流空气相干扰。 因此，鼓风机单元可以减少由此而产生的第二噪音，而不会大大降低送风能力。

    摘要： In a centrifugal blower in which the outer periphery of an intake opening is arranged outside of the inner edge of a main blade, a large number of sub blades are provided in the intake opening at a location corresponding to the main blade. The sub blades lead the secondary air flowing from an outside area of the intake opening to a rotating direction of a centrifugal multi blade fan. Thus, the secondary air flows from the sub blade to the main blade smoothly, thereby increasing a secondary air flow amount and reducing air flow noise.

    摘要： A scroll casing of a centrifugal blower holds a centrifugal fan therein and defines an air passage around the centrifugal fan. The scroll casing has a scroll starting position at the most upstream portion of the air passage, a scroll ending position at a downstream portion thereof, and an air outlet at the most downstream side thereof. Between the scroll ending position and the air outlet, the scroll casing has a warped face and a guide face. Accordingly, an air flow flowing apart from the fan and an air flow flowing close to the fan are prevented from mixing with each other. As a result, interference between the air flows and blades of the fan is generally prevented, whereby noise is decreased.

    摘要： An inner diameter (d.sub.2) of a centrifugal-type multiple-vane fan at a side where the motor is inserted (i.e., the insertion side) is larger than an inner diameter (d.sub.1) of the centrifugal-type multiple-vane fan at a side where the motor is not inserted (i.e., the non-insertion side), such that the ratio of a difference between an outer diameter (D) and the inner diameter (d.sub.2) of the centrifugal-type multiple-vane fan of the insertion side to a difference between the outer diameter (D) and the inner diameter (d.sub.1) of the centrifugal-type multiple-vane fan of the non-insertion side is in a range of 0.6-0.95. Thus, a centrifugal-type blower having the centrifugal-type multiple-vane fan can obtain a desired air volume while maintaining a small size of the centrifugal-type blower.

    摘要： A bell-mouth ring is formed with a casing to be disposed proximately at an outer radial side of a shroud. The bell-mouth ring has a deflection wall surface for deflecting a flow of air blown out radially outwardly from the centrifugal multi-blade fan and further flowing radially inwardly toward the rotation axis along an inner wall surface of the casing, toward the driving means. In this way, it is possible to suppress air from flowing backward to a suction port through a gap between the shroud and the bell-mouth ring. Accordingly, it is possible to reduce the noise generated by an interference of the air sucked from the suction port with the air flowing backward or by the turbulence of the air flow which is generated in the gap.

    摘要： An air conditioning system suitable for automotive application is disclosed, in which the noise in the frequency range of about 1 kHz to 2 kHz is reduced. At least a sound absorbing member is arranged over the portions extending from a turning section of an air path where the air blown under pressure from a blower impinges and changes direction toward a heat exchanger, i.e. from the spiral end of a scroll casing to the front of an evaporator.

    摘要： A centrifugal blower is provided with a casing which defines a spiral duct and a centrifugal fan which is rotationally provided within the casing. The centrifugal fan has a bottom plate and a plurality of blades which are equally spaced along the periphery of the bottom plate. The plurality of blades extends parallel to the rotational axis. The duct is arranged to reduce the size of a low velocity air flow zone which is generated in an upper radially outer region in the spiral duct. The low velocity air flow zone, which appears in an upper radially outer region in the air duct, is reduced to reduce surging in the blower.
