离心风机及具有其的吸尘器
摘要：
本发明公开了一种离心风机及具有其的吸尘器，离心风机包括：壳体、叶轮、静叶组件和电机。壳体具有进风口和出风口，叶轮设在壳体内且邻近进风口设置，静叶组件设在壳体内且位于叶轮的下游，静叶组件与壳体的内壁之间限定出适于气流流动的风道，风道的平行轴线截面呈“U”形，电机设在静叶组件的下游且与叶轮相连。根据本发明的离心风机，通过将静叶组件与壳体之间限定出的风道的平行轴线截面设置呈“U”形，可以有效地减小气流在风道内流动的过程中产生的损失，且可以降低噪声。
摘要（英）：

The invention discloses a centrifugal fan and a dust collector with the same. The centrifugal fan comprises a shell, an impeller, a stationary blade assembly and a motor. The shell is provided with an air inlet and an outlet. The impeller is arranged inside the shell and adjacent to the air inlet. The stationary blade assembly is arranged inside the shell and located on the downstream portion of the impeller. An air duct suitable for airflow to flow is defined between the stationary blade assembly and the inner wall of the shell. The parallel axis section of the air duct is in a U shape. The motor is arranged on the downstream portion of the stationary blade assembly and is connected with the impeller. According to the centrifugal fan, due to the fact that the parallel axis section of the air duct defined between the stationary blade assembly and the shell is set to be in the U shape, losses caused when the airflow flows in the air duct can be effectively reduced, and noise can be lowered.
