To provide a centrifugal blower having a high blowing efficiency. An internal space (A1, A2) of a scroll housing (40) is divided by a dividing wall portion (43b) into a one-side space (A1) and an other-side space (A2). A boundary between a circumferential surface portion (43a) and the dividing wall portion (43b) comprises a one-side boundary portion (44) formed to face the one-side space, and an other-side boundary portion (45) formed to face the other-side space (A2). At least one of the one-side boundary portion (44) and the other-side boundary portion (45) is formed in a curved shape extending in the circumferential direction of a rotating shaft (32a).
提供一种送风效率高的离心鼓风机。涡壳(40)的内部空间(A1、A2)被分割壁部(43b)分割为一方侧空间(A1)和另一方侧空间(A2)。周面部(43a)与分割壁部(43b)的边界由以面向一方侧空间的方式形成的一方侧边界部(44)和以面向另一方侧空间(A2)的方式形成的另一方侧边界部(45)构成。一方侧边界部(44)或另一方侧边界部(45)的至少一方在旋转轴(32a)的周向范围形成为弯曲状。
