601902 A cyclone separator comprising a primary cyclone portion 10 including a primary inlet through which air containing dust sucked from outside enters, a primary swirl chamber 12 that swirls the air containing dust sucked in from the primary inlet 11 to separate dust from the air, a primary dust case 114 that collects the dust separated by the primary swirl chamber 12 from a primary opening portion provided in a lower part of the primary swirl chamber 12, a primary outlet that discharges the air in the primary swirl chamber and a secondary cyclone portion 20. The secondary cyclone portion 20 comprises a secondary inlet 21 through which air discharged from the primary outlet enters, a secondary swirl chamber 22 that swirls the air sucked in from the secondary inlet to further separate dust from the air, a secondary dust case 24 that collects the dust separated by the secondary swirl chamber 22 from a secondary opening portion provided in the secondary swirl chamber 22, and a secondary outlet that discharges the air in the secondary swirl chamber 22. The primary cyclone portion 10 includes a zero-order dust case 114 that collects the dust separated by the primary swirl chamber from an opening portion provided in a side wall of the primary swirl chamber. The zero-order dust case 114 is placed so as to cover at least a part of the secondary cyclone portion. |
