Abstract (en)
[origin: EP2277425A1] A turbine brush unit (100a) and a vacuum cleaner having the same are provided. The turbine brush unit (100a) may include a turbine brush case (101), a brush member (102) mounted in the turbine brush case (101), and a turbine fan unit (120, 130) having a plurality of wings (122, 132) and rotating the brush member (102). Each of the plurality of the wings (122, 132) may have a curvature point (C1, C2), a primary collision surface (120a', 130a') with which a primary inlet wind (A1) drawn through the inlet portion (103a) of the turbine fan unit (120, 130) collides and a secondary collision surface (120b', 130b') with which a secondary inlet wind (A2) collides. The primary and secondary inlet winds (A1, A2) apply a force in the rotation direction (D) of the turbine fan unit (120, 130).
