Cyclonic separator with noise reducing feature

摘要

A cyclonic separating apparatus (300) includes a cyclone body (310) having a cyclone chamber (313) and a dust-collecting chamber (315). A cover unit (330) is connected to an upper portion of the cyclone body (310), and an openable door unit (350) is mounted to a lower portion of the cyclone body At least one noise-reducing rib (317, fig.3) is provided in an air discharge pipe (314, fig.3) of the cyclone chamber (313). The noise-reducing rib is preferably configured to be curved (as depicted in fig. 4) and also serves to convert the swirling motion of the air into a straightened flow.
