In addition, the step (a); It is preferable that the first pressing plate 310 further comprises (a3) steps (S130, S140) of continuously pressing dust for a predetermined time in a state where it reaches a peak that can no longer rotate.

Here, the first pressing plate 310 is repeated to rotate in a direction opposite to one direction at a predetermined angular speed.

A process of compressing dust by the dust compression method as described above will be described with reference to FIGS. 10A to 10E.

First, when power is supplied to a vacuum cleaner, an air suction force is generated by the air suction device, and external air containing dust is sucked into the suction nozzle by the air suction force.

The outside air sucked through the suction nozzle is introduced into the suction port 211a of the main cyclone through the main body suction port 110.

Air introduced through the inlet port 211a of the main cyclone is guided in a tangential direction to the inner wall of the main cyclone 211 to form a spiral flow, so that the dust contained in the air due to the difference in centrifugal force with the air Separated and descended.

As described above, the dust falling while spirally flowing along the inner wall of the main cyclone 211 passes through the dust inlet 231 of the partition plate 230 and is stored in the main chamber 221.

The air from which dust is first separated by the main cyclone 211 is discharged through the discharge port 211b through the exhaust member 211c and then flows into the auxiliary cyclone.

Accordingly, the dust separated by the cyclone principle inside the auxiliary cyclone is stored in the auxiliary dust chamber 224, and the air which has undergone the dust separation process again in the auxiliary cyclone is discharged from the auxiliary cyclone, and then the fan- It is discharged from the cleaner body 100 through the body discharge unit 120 via a motor assembly.

Meanwhile, the main chamber 221 stores most of the dust introduced into the vacuum cleaner, and the dust inside the main chamber 221 is formed on the first pressing plate 310 and the second pressing plate 320. By compressing by minimizing the volume, it is possible to store a large amount of dust inside the main chamber 221.

In more detail, as shown in FIG. 11A, the first pressing plate 310 rotates in one direction toward one side of the second pressing plate 320 to sweep and press the dust inside the main chamber 221. While reducing the volume of dust.

When the first pressing plate 310 reaches the peak, dust is continuously pressed to one side of the second pressing plate for a predetermined time (about 3 to 5 seconds).

Next, as shown in FIG. 11B, the first pressing plate 310 rotates in the opposite direction toward the opposite side of the second pressing plate 320 to collect and press the dust inside the main chamber 221 and press the dust. Reduce the volume of

When the first pressing plate 310 reaches the peak, dust is continuously pressed to the opposite side of the second pressing plate 320 for a predetermined time (about 3 to 5 seconds).

This process is repeated continuously during operation of the vacuum cleaner, as shown in Figs. 11A to 11D.

On the other hand, the rotation range of the first pressing plate 310 during the operation of the vacuum cleaner is input to the control unit of the cleaner body 100, and thus the amount of dust collected in the dust container 220 is roughly calculated.

As shown in FIG. 11E, when the rotation range of the first pressing plate 310 is narrowed below a predetermined angle, the user is notified to the outside.

As described above, the dust container 220 in which dust is stored in a compressed state therein is separated from the cleaner body 100 by the user at an appropriate time and is emptied.

In other words, when the user detaches the dust container 220 from the cleaner body 100 and flips the dust container 220, the compressed dust inside the dust container is discharged to the outside.

In addition to the embodiments described above, the fact that the present invention can be embodied in other specific forms without departing from the spirit and scope will be apparent to those skilled in the art.

Therefore, the above-described embodiments should be regarded as illustrative rather than restrictive, and thus, the present invention is not limited to the above detailed description, but may vary within the scope of the appended claims and their equivalents.
