It is preferable that one side surface 218a forming the air intake passage be inclined so as to widen downwardly.

Therefore, as shown in FIG. 7, when the dust collecting container 210 is viewed along the axis of the first suction port, the outlet portion 217 is covered by the guide rib 218.                     

As a result, the air flowing into the first inlet 214a is prevented from being directly introduced into the outlet 217 by the guide rib 218, and the entire air flowing into the first inlet 214a is prevented. It is guided in a tangential direction to the inner wall of the primary cyclone portion 214 to improve the turning force for the separation of foreign matter, and at the same time minimize the air flow resistance flowing into the first inlet (214a) f.

Referring to the operation of the vacuum cleaner having an embodiment of the above-described dust collector according to the present invention.

First, when the vacuum cleaner is operated, external polluted air flows into the primary cyclone unit 214 through the suction nozzle and the connection pipe.

The air flowing into the primary cyclone portion 214 is not directly introduced into the outlet portion 217 by the first suction port 214a and the guide rib 218, but the primary cyclone portion ( The inner wall of the 214 is tangentially guided to form a spiral flow.

Accordingly, the dust having a relatively heavy weight and large dusts are separated and lowered by the cyclone principle, and are stored in the primary dust storage unit 212, and the dust stored in the primary dust storage unit is the re-scattering preventing member 219. ) And the curved boundary wall 216 is prevented from scattering.

In addition, the air from which the relatively large dusts are separated is discharged to the first exhaust port 214b communicating with the plurality of through holes formed on the side of the outlet portion 217 and then to the plurality of secondary cyclone portions 215. It enters and goes through the dust separation process again.

Air from which relatively small dusts are separated from the secondary cyclone unit 215 is introduced into the upper cover 230 through the second exhaust port 215b and the third exhaust port 221.

After the air flowing into the upper cover 230 is filtered by the filter, the air is discharged backward through the fourth exhaust port 232, and the air discharged from the fourth exhaust port 232 is rear part of the cleaner body. Passed through the predetermined flow path formed in the discharge to the outside of the cleaner body.
