In addition, the filter unit 190 has a lower end fixed to the lower side of the support part 164, and the upper end is closely supported on the upper side of the support part 164.

On the other hand, the exhaust flow path 118 guides the air to flow through the first discharge flow path 182 and the second discharge flow path 184 to be discharged to the outside in a laminated state.

As the second discharge passage 184 branched from the connection passage 170 is formed, a part of the air discharged from the first cyclone unit 230 is partially discharged from the secondary cyclone unit 300. ) Is immediately discharged through the second discharge passage 184 without passing.

Therefore, the flow path resistance of the air passing through the second discharge flow path 184 is reduced, which causes the flow resistance of the entire air flowing inside the vacuum cleaner 10 to be reduced, resulting in improved suction power of the vacuum cleaner. .

Hereinafter, the operation of the vacuum cleaner will be described.

When power is applied to the vacuum motor of the vacuum cleaner 10, suction force is generated by the vacuum motor, and air containing dust is sucked into the suction nozzle by the suction force.

In addition, the air sucked through the suction nozzle is introduced into the cleaner body 100 through the main body suction part 110, and the introduced air is introduced into the dust collecting unit 200 through the communication flow path 112. .

In detail, the air containing the dust is sucked in the tangential direction of the first cyclone unit 230 through the first air inlet 212 of the dust collecting body 210. Then, the sucked air falls while turning along the inner circumferential surface of the first cyclone portion 230, and in this process, the air and the dust are separated from each other while receiving different centrifugal forces by the weight difference.

The dust separated air is filtered through the through hole 262 of the filter member 260 and then discharged to the outside of the dust collecting unit 200 through the discharge hole 251 and the first air outlet 252. do.

On the other hand, the separated dust is introduced into the dust guide flow path 232 in the tangential direction in the process of turning along the inner circumferential surface of the first cyclone portion 230.

Dropped downward through the) is stored in the first dust storage unit 214.

Meanwhile, the air discharged through the first air outlet 252 is introduced into the cleaner body 100. In addition, some of the air introduced into the cleaner body 100 flows into the second cyclone unit 300 through the connection flow path 170.

Then, the air is guided in the tangential direction to the inner wall of the secondary cyclone portion 300, respectively, and the dust is separated again while flowing therein.

In addition, the air from which the dust is separated again flows into the first discharge passage 182. In addition, the air introduced into the first discharge passage 182 passes through the filter unit 190 and is discharged to the outside through the main body discharge part of the cleaner body 100 after passing through the vacuum motor.

On the other hand, the separated dust is introduced into the dust collecting unit 200 through the dust inlet 254, and finally stored in the second dust storage unit 216.

Meanwhile, another part of the air introduced into the connection flow path 170 is discharged to the second discharge flow path 184.

In addition, the air introduced into the second discharge flow path 184 is combined with the air of the first discharge flow path 182 passing through the filter unit 190, flows into the exhaust flow path 118, and then moves to the vacuum motor side. . In this case, as described above, the suction resistance of the vacuum cleaner 10 is improved by reducing the flow resistance of the air passing through the second discharge flow path 184.

Meanwhile, in order to empty the dust stored in the dust collecting body 210, the user separates the dust collecting unit 200 from the cleaner body 100.

In addition, the cover member 250 to which the first cyclone unit 230 is coupled is separated from the dust collecting unit 200. Then, the dust collecting body 210 is reversed to empty the dust.
