A cyclonic separator and a vacuum cleaner which efficiently separates dust, collect the dust without re-scattering it and make low noise are provided. In a primary cyclone portion, a primary swirl chamberswirls air containing dust sucked from a primary inlet, and thereby, separates a first dust and a second dust from the air containing dust to collect them respectively in a zero-order dust casewhich is provided at a side of the primary swirl chamberand communicates with a zero-order opening portionprovided at a side wall, and a primary dust caseprovided at a lower side of the primary swirl chamber. In a secondary cyclone portion, a secondary inletwith an opening area smaller than that of a primary outlet bodysucks air exhausted from the primary outlet body, a secondary swirl chamberswirls the first air to separate the second dust which is finer than the first dust from the first air to collect the second dust in a secondary dust caseprovided at a lower side of the secondary swirl chamber. With regard to the cyclonic separator with such a configuration, the zero-order dust caseis formed to cover at least a part of the secondary cyclone portion

Cyclone separator and vacuum cleaner

A vacuum cleaner including a suction port body, a motor-driven blower, and a cyclone part that is disposed between the suction port body and the motor-driven blower and is provided with an inflow port, a swirl chamber, and a discharge port body. The side surface of the discharge port body is composed of a cylindrical mesh and a conical mesh. The side wall of the swirl chamber is composed of a cylindrical part and a conical part. The vacuum cleaner further includes a zero-order opening formed by opening a part of the cylindrical part, a first-order opening formed by opening a part of the conical part, a zero-order dust case communicating with the swirl chamber via the zero-order opening, and a first-order dust case communicating with the swirl chamber via the first-order opening.
