Meanwhile, referring to FIGS. 4 and 7, the primary dust storage unit 212 and the secondary dust storage unit 213 are provided inside the dust collecting container 210 to form an internal space of the dust storage unit. It is formed by the boundary wall 219 which divides. Here, the boundary wall 219 is a substantially cylindrical shape having a radius smaller than the outer wall of the dust collecting container 210 and larger than the primary cyclone portion 214, and the boundary wall 219 is the secondary cyclone. It is preferable that the lower portion of the unit 215 is integrally connected and extended downward.

In addition, on the inner circumferential surface of the boundary wall 219, a plurality of grooves 219a recessed in the radial direction, that is, the secondary dust storage unit 213, are formed long in the vertical direction, respectively, and have a curved shape in the circumferential direction. .

Here, each of the grooves 219a formed on the inner circumferential surface of the boundary wall 219 may have a portion extending downward between the foreign matter discharge ports 215e to protrude toward the secondary dust storage unit 213. .

The reason is that most foreign matters and bulky foreign matters are separated from the primary cyclone part 214 and stored in the primary dust storage part 212, so that dust is accommodated in the primary dust storage part 212. This is because space must be secured at maximum.

In more detail, the boundary wall 219 includes a plurality of curvatures 219b arranged in the circumferential direction and a plurality of outer parts 219c interconnecting the plurality of curvatures 219b. .

Here, the dozens of curvatures 219b extend vertically downward from the inner semicircle rim of the foreign matter outlet 215e and have a vertical cross section having the same shape as the inner semicircle rim of the foreign matter outlet 215e.

The outer portions 219c are provided between the curvatures 219b to block the curvatures 219b. The outer portions 219c interconnect the curvature portions 219b to form grooves 219a of the boundary wall.

Accordingly, the boundary wall 219 has a curved shape in the circumferential direction as a whole.

In addition, the lower end of the boundary wall 219 is formed longer than the lower end of the primary cyclone portion 214, and extends to the bottom of the dust collecting container 210, that is, the upper surface of the lower panel 211. .

Accordingly, the boundary wall 219 prevents the primary dust storage unit 212 and the secondary dust storage unit 213 from communicating with each other, and at the same time, stores the dust in the primary dust storage unit 212. It expands the space.

In addition, the boundary wall 219 prevents dust stored in the primary dust storage unit 212 from being scattered by the spiral flow due to the spiral flow formed in the primary cyclone portion 214.

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.

Air flowing into the primary cyclone portion 214 is not directly introduced into the outlet portion 216 by the first suction port 214a and the guide rib 217, but the primary cyclone portion ( The inner wall of the 214 is tangentially guided to form a spiral flow.

Accordingly, the dust, which is relatively heavy and large in weight, is separated and lowered by the cyclone principle and stored in the primary dust storage unit 212, and the dust stored in the primary dust storage unit 212 is scattered. 218 and scattering are prevented by the boundary wall 219 having a curved inner circumferential surface.

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 at the side of the outlet portion 218, 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. It is discharged to the outside of the cleaner body through a predetermined flow path formed in the.

On the other hand, the dust collector according to the present invention described above can be installed and used in the canister type vacuum cleaner and upright cleaner.

The dust collector of the vacuum cleaner according to the present invention having the above configuration has the following effects.

According to the dust collector of the vacuum cleaner according to the present invention, a plurality of grooves radially recessed are formed in the inner circumferential surface of the boundary wall to maximize the receiving space of the primary dust storage unit for storing most of the separated foreign matter and the dust collection performance is improved. Is improved.                     

In addition, according to the dust collector of the vacuum cleaner according to the present invention, the boundary wall is formed to be bent in the circumferential direction, thereby preventing the formation of spiral flow in the dust storage unit, thereby preventing the scattering of stored foreign matter.
