Abstract:
[Problem] The present invention provides a compact cyclone device able to separate and recover dust without stirring up the dust. [Solution] The cyclone device (1) comprises a primary swirling chamber (23) having a primary dust-collecting chamber (11), a primary suction passage (37) communicating with the primary swirling chamber (23), and a primary discharge passage (68) communicating vertically with the primary swirling chamber (23). The cyclone device (1) also comprises a primary cyclone (4) for collecting dust in the primary dust-collecting chamber (11) by swirling the air flowing in from the primary suction passage (37) through the primary swirling chamber (23) and then discharging the air from the primary discharge passage (68), a secondary suction passage branching vertically from the primary suction passage (37), a secondary swirling chamber (62) provided above the primary swirling chamber (23) and communicating with the secondary suction passage, a secondary discharge passage (69) communicating vertically with the secondary swirling chamber (62), a secondary dust-collecting chamber (30) communicating with the secondary swirling chamber (62) and separate from the primary dust-collecting chamber (11), and a secondary cyclone (5) for collecting dust in the secondary dust-collecting chamber (30) by swirling the air flowing in from the secondary suction passage through the secondary swirling chamber (62) and then discharging the air from the secondary discharge passage (69).
