First, when a vacuum cleaner is operated by applying power, 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 sucked foreign matter is introduced into the dust collecting container 310 through the suction guide 312 of the dust collecting unit 300. Inflow.

The air including the foreign matter introduced into the dust collecting container 310 through the suction guide 312 is circulated while rotating along the inner wall of the dust collecting container 310, and the foreign material having a relatively large mass is the falling portion 362. Passed through and stacked on the lower side of the separation plate 360, the foreign material having a relatively low mass rotates along the outer circumferential surface of the filter 350 and is filtered by the filter 350.

The air discharged to the outside of the dust collecting unit 300 is passed through a motor (not shown) and then cleaning while repeating the discharge process to the outside through the discharge unit 290 mounted on the outer surface of the main body 200 Is performed.

On the other hand, when a lot of foreign matter such as dust (D) is accumulated inside the dust collecting container 310 to operate the foreign material compression means 355 to compress the dust (D). In order to operate the foreign material compression means 355, first, the pressing member 380 inserted into the dust collecting handle 314 is drawn out in the state as shown in FIG. Then, when the pressing member 380 is drawn out, the lower end is inserted into the upper portion of the guide rod 370 while holding the upper end of the pressing member 380.

At this time, the lower edge of the pressing member 380 is in contact with the top surface of the support rib 372, the pressing member 380 is applied to the support rib 372 by the downward force applied by the user. The guide rod 370 is caused to flow downward.

In addition, when the guide rod 370 flows downward, the separation plate 360 fixedly coupled to the bottom surface of the guide rod 370 also flows downward at the same time, and is applied to the downward force transmitted from the pressing member 380. The dust (D) collected in the lower portion of the dust collecting container 310 is compressed by the bottom surface of the separator 360 to reduce its volume.

Next, when the dust compression inside the dust collecting container 310 is completed by the above-described action, the downward force applied to the pressing member 380 is removed. When the force applied to the pressing member 380 is removed, the guide rod 370 flows upward by the elastic restoring force of the elastic member E, and at the same time, the separation plate 360 is also returned to its original position to recover the dust collecting unit. 300 is a state in which the foreign material can be filtered.

At this time, the filter brush 392, which has been lowered to the lower end of the filter 350 in conjunction with FIG. 6 and the foreign material compression means 355, moves upward again to return to the upper end of the filter 350 as shown in FIG. do.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

The dust collecting unit for a vacuum cleaner according to the present invention as described above constitutes a foreign material compressing means for forcibly flowing downward by the user's force to compress the foreign matter accumulated in the dust collecting unit.

Therefore, there is an advantage that the inconvenience of having to empty the dust collected frequently during the cleaning is effectively utilized by effectively utilizing the internal space of the limited dust collecting container. In addition, since the foreign matter inside the dust collecting chamber is compressed, the scattering of dust generated when emptying the foreign matter is prevented, thereby increasing the convenience of use.

In addition, the present invention is also provided with a foreign material removal means interlocked with the foreign material compression means so that the foreign material attached to the outer peripheral surface of the filter is removed at the same time when the foreign material compression. As a result, clogging of the filter is prevented and a lowering of the suction force of the vacuum cleaner is prevented. That is, the performance improvement of a vacuum cleaner is anticipated.
