First, when the vacuum cleaner is operated, the cyclone fan 3 is operated and at the same time, suction air sucked from the suction head (not shown) is introduced into the vacuum cleaner body.

The suction air introduced into the vacuum cleaner main body is introduced into the first dust collecting unit 10 through the suction port 21, in which case the suction air is rotated in the first dust collecting unit 20 and included in the suction air by the centrifugal force. The dust or various foreign matters are separated, and the dust or various foreign matters thus separated are collected into the first dust collecting chamber 30 through the first and second through holes 27 and 31 communicating with each other.

Relatively large particles of dust or various foreign matter cannot pass through the fine mesh filter 23 of the first dust collecting unit 20, but relatively small particles of dust or various foreign matter pass through the fine mesh filter 23 together with air. After flowing into the lower casing 10 through the discharge passage 25, it is introduced into the second dust collecting unit 40 along the suction passage 51 formed in the second dust collecting chamber 50.

The suction air introduced into the second dust collecting unit 40 after being first collected by the first dust collecting unit 20 is rotated in the second dust collecting unit 40, and dust or various kinds of dust contained in the suction air by the centrifugal force thereof. The foreign matter is separated again, and the dust or various foreign matters thus separated are collected into the second dust collecting chamber 50 through the third and fourth through holes 47 and 53 communicating with each other.

Relatively small particles of dust or various foreign matters do not pass through the HEPA filter 43, and only the air purified by the first and second dust collecting units 20 and 40 passes through the HEPA filter 43 Through 45).

In the case of the cyclone dust collector 1 for a vacuum cleaner according to the present invention, the first dust is collected by the first dust collecting unit 20 to separate dust or various foreign matters contained in the intake air first, and then By separating the dust or various foreign matters of the relatively small particles contained in the air passing through the primary dust collecting unit 20 through the secondary dust collecting by the second dust collecting unit 40 to exhibit excellent dust collection performance.

Although the cyclone dust collector 1 for the vacuum cleaner 1 according to the present invention may be used as it is, the discharge passage 25 of the primary dust collecting unit 20 in the inner space 11 of the lower casing 10 described above. ) May be used to accommodate the water to be submerged below the surface, in this case, as the suction air passing through the fine mesh filter 23 of the first dust collecting unit 20 is discharged into the water contained in the lower casing (10) Since the dust and foreign matter contained in the intake air is adsorbed by the water, the purge air discharged from the water may be introduced into the secondary dust collecting unit 40 through the suction passage 51 of the secondary dust collecting chamber 50. As a result, the lower casing 10 serves as a water filter connecting the primary and secondary dust collecting units 20 and 40. As a result, while minimizing contamination of the HEPA filter 43 installed in the secondary dust collecting unit 40, it is possible to exhibit more excellent air purification performance.

In addition, the dust or various foreign matters collected in the primary dust collecting unit 20, the first dust collecting chamber 30, the secondary dust collecting unit 40 and the second dust collecting chamber 50, the first and second cover (60, The primary dust collecting unit 20, the first dust collecting chamber 30, the secondary dust collecting unit 40 and the second dust collecting chamber 50 may be separated from each other and discharged to the outside.

In addition, when the water in the lower casing 10 is contaminated to some extent, the second cover 70 is removed to remove the secondary dust collecting unit 40 and the second dust collecting chamber from the seating groove 13 of the lower casing 10. Discharge to the outside through the opening formed by separating the 50, in this case, as the dust or foreign matter of the relatively large particles in the intake air is pre-collected by the primary dust collecting unit 20, the water drain Emissions will not cause sewer clogging or work.

As described above, according to the cyclone dust collector for a vacuum cleaner according to the present invention, after separating the dust or various foreign matters of relatively large particles through the primary dust collector unit having a fine mesh filter, the secondary dust collector unit having a HEPA filter By further separating the dust or various foreign matter of relatively small particles through, it is possible to exhibit more excellent dust collection performance.

In addition, the HEPA filter installed in the secondary dust collecting unit is formed by forming a kind of water filter unit between the primary and secondary dust collecting units by receiving water so that the discharge passage of the primary dust collecting unit is submerged below the water surface in the inner space of the lower casing. Minimize contamination and at the same time have the advantage of exerting better air purification performance.

In addition, the first dust collecting unit communicates with the first dust collecting unit to collect dust or various foreign matters separated by the first dust collecting unit therein, and the second dust collecting unit communicates with the second dust collecting unit. By collecting dust or various foreign matters of relatively small particles separated by the second dust collecting unit therein, it is possible to maximize the dust collecting capacity.

In addition, through the opening and closing cover structure, there is an effect that can easily discharge the dust or various foreign matter in the first and second dust collection unit and the primary and secondary dust chamber.
