Hereinafter, the action of the dust collecting unit for the vacuum cleaner having the configuration as described above.

First, when the vacuum cleaner is operated, suction power is generated by a motor (not shown) built in the main body 200. When the suction force is generated in this way, the air including the foreign matter is sucked by the suction nozzle body 100, and the air including the foreign matter is introduced into the dust collecting unit 300 through the suction guide 322 of the dust collecting unit 300. .

Among the foreign materials introduced into the upper dust collector 320, the foreign material having a relatively large mass is accumulated to the lower side through a gap between the outer circumferential surface of the separator 332 and the inner circumferential surface of the upper dust collector 320, and relative As a foreign substance having a low mass is circulated, it is introduced into the filter unit 330.

That is, foreign matter having a small mass is separated by the filter unit 330 in the process of moving together with air to escape through the exhaust port 352, and the purified air passes through the filter unit 330 and passes through the exhaust port. It is discharged to the outside of the dust collecting unit 300 through the (352).

The air discharged to the outside of the dust collecting unit 300 passes through a dust collecting exhaust seal (not shown) formed in the dust collecting unit 270 via a motor (not shown) and then mounted on the outer surface of the main body 200. The cleaning is performed while being discharged to the outside of the cleaner through the discharge unit 290.

On the other hand, when a cleaner is used for a long time, many foreign matters accumulate inside the dust collecting unit 300, and when such a large amount of foreign matter accumulates, suction power is lowered and the cleaning performance of the cleaner is rapidly reduced, so that the user collects the dust collecting unit 300. The foreign matter accumulated inside is emptied.

Looking at the process of emptying the foreign material in the dust collection unit 300, first, the dust removal unit 260 by pressing down to separate the dust collection unit 300 from the main body 200 of the vacuum cleaner. That is, when the detachable knob 260 is pressed and the handle 324 of the dust collecting unit 300 is pulled forward, the dust collecting unit 300 is completely separated from the main body 200.

When the dust collecting unit 300 is separated from the main body 200, the upper cover 350 is rotated clockwise (as shown in FIG. 4) while the upper cover 350 and the lower cover 340 are gripped with both hands. Rotated. At this time, the sliding protrusion 326 is slid along the guide groove 312, the upper dust collector 320 is flowed downward while rotating clockwise from the outside of the lower dust collector (310).

When the upper dust collecting tube 320 flows downward while rotating clockwise, the filter unit 330 fixedly mounted on the bottom surface of the upper cover 350 also flows downward while simultaneously rotating, and the filter unit 330. The bottom of the separator 332 integrally formed with the filter unit 330 at the end of the) is to compress the foreign matter collected in the lower dust collector (310) as shown in FIG.

That is, foreign matter in the lower dust collecting container 310 compressed by the separating plate 332 is aggregated while reducing the volume to prevent scattering (飛散). Then, the upper cover 350 is lifted to open the inside of the upper dust collecting container 320. When the top cover 350 is opened, the filter unit 330 mounted on the bottom surface of the central part of the top cover 350 is also simultaneously removed, and the filter unit 330 can be washed.

On the other hand, the lower portion of the dust collecting unit 300, that is, in order to empty the heavy foreign matter collected in the lower dust collector 310, the open lever 314 is pressed downward. When the open lever 314 is pressed, the lower cover 340 is rotated downward by gravity to be opened, and at the same time, heavy foreign matter falls outward from the inner space of the lower dust collecting container 310 to be emptied.

At this time, the heavy foreign material is compressed by the separator 332 as described above, so that it is not scattered in the falling process, so that the post-treatment such as a plastic bag is facilitated.

On the other hand, after the foreign matter inside the dust collecting unit 300 is completely removed, the process of mounting the inside of the dust collector mounting portion 270 by the reverse order of the foreign material removal process, the upper dust collector 320 in the state as shown in FIG. ), The upper cover 350 is rotated counterclockwise (as shown in FIG. 6) while the upper cover 350 and the lower cover 340 are gripped by both hands.

At this time, the sliding protrusion 326 is guided to the upper dust collecting tube 320 while sliding along the guide groove 312. When the sliding protrusion 326 reaches the upper end of the guide groove 312, that is, the flow preventing groove 312 ', the sliding protrusion 326 is no longer rotated and interferes with the upper dust collecting tube 320 to its original position. It returns to the state which can remove a foreign material, ie, it is a state like FIG.
