If foreign substances stored inside the dust collecting device 100 are discharged by the suction force of the cleaner station 2 without rotation of the rotating part 500, some foreign substances such as hair are collected without being separated from the cyclone module 300. It may remain inside the case 210 . In this case, the user may experience inconvenience in having to separately remove foreign substances remaining in the dust collection case 210 .

On the other hand, in the cyclone module 300 according to the embodiment, foreign substances remaining inside the dust collection case 210 can be minimized by rotating the rotating part 500 in the process of discharging foreign substances.

However, in a dust collection process other than a process of discharging foreign substances of the dust collector 100, rotation of the rotating unit 500 may rather degrade dust collection performance. For example, a gap may occur between the rotating part 500 and the fixed part 400, and dust may flow in or unintentional flow may occur through the gap. Considering this point, the rotation unit 500 of the cyclone module 300 according to the embodiment may be configured to rotate in the process of discharging dust, but to limit rotation in the process of collecting dust.

Referring to FIGS. 8 and 9 , rotation of the rotation unit 500 may be selectively allowed according to the position of the discharge door 220 . The rotating part 500 has a rotating state 501 capable of rotating with respect to the fixing part 400 when the discharge door 220 is in the open position 221 and a fixed part when the discharge door 220 is in the blocking position 222. It can have a locked state 502 where rotation about 400 is limited. Accordingly, in the dust collecting device 100 according to the embodiment, when the foreign matter is discharged to the outside through the foreign matter outlet 213 of the dust collecting case 210, the rotating part 500 rotates to induce the discharge of the remaining foreign matter, When the foreign matter outlet 213 of the dust collecting case 210 is blocked by the discharge door 220 and foreign matter is collected inside the dust collecting case 210, the rotation unit 500 is fixed to prevent degradation of dust collecting performance.

As an example for this, as shown in FIG. 9, when the discharge door 220 is switched from the blocking position 222 to the open position 221, the rotating part 500 descends and moves from the locked state 502 to the rotating state 501. can be converted to As shown in FIG. 8 , when the discharge door 220 is switched from the open position 221 to the blocking position 222, the rotating part 500 rises to switch from the rotating state 501 to the locked state 502. .

The dust storage unit 530 and the support wall 540 may be assembled and fixed. The dust storage unit 530 and the support wall 540 may be assembled by the coupling protrusion 535 and the coupling groove 545 . A sealing member 550 may be disposed between the dust storage unit 530 and the supporting wall 540 .

The support wall 540 may be assembled and fixed to the inner case 510 . For example, after the support wall 540 approaches the inner case 510 so that the cam protrusion 514 formed on the inner circumferential surface of the inner case 510 is inserted into the cam groove 541 formed on the support wall 540 The support wall 540 may be fixed to the inner case 510 by rotating it.

In the above-described example, the configuration of the rotating unit 500 is limited to the inner case 510 and the dust separation member 520, but the configuration of the rotating unit 500 is not limited thereto, and for forming the first cyclone 101 It may include a variety of configurations.

Referring to FIGS. 8 and 11 , the fixing part 400 has a fixed configuration without being rotated in the cyclone module 300 and is mounted to be fixed to the dust collecting case 210 .

Referring to FIG. 8 , the cyclone module 300 further includes a rotation preventing member 560 preventing the rotating part 500 from rotating with respect to the fixed part 400 . When the rotating part 500 is in the locked state 502, the anti-rotation member 560 provides a rotational frictional force between the rotating part 500 and the fixed part 400, thereby preventing the rotation of the rotating part 500 with respect to the fixed part 400. Rotation can be prevented.

The anti-rotation member 560 is elastically deformable and may include an elastic member disposed on at least one of the rotation unit 500 and the fixing unit 400 . For example, the anti-rotation member 560 may include a first elastic member 561 disposed on an outer circumferential surface of the rotation unit 500 and a second elastic member 562 disposed below the fixing unit 400. .

As shown in FIG. 8 , when the discharge door 220 is in the blocking position 222 , the discharge door 220 contacts the rotating part 500 and presses the rotating part 500 upward, that is, toward the fixing part 400 . The rotation preventing member 560 is compressed and deformed by the rotating part 500 . As shown in FIG. 9 , when the discharge door 220 is in the open position 221, the discharge door 220 is spaced apart from the rotation unit 500, and the rotation preventing member 560 releases compression deformation by the rotation unit 500. And, the rotating part 500 is rotatable with respect to the fixing part 400.

The first elastic member 561 may be disposed to overlap the fixing part 400 in the vertical direction. Accordingly, as shown in FIGS. 8 and 12A, when the rotating part 500 rises and is positioned in the locked state 502, the first elastic member 561 is compressed and deformed by the fixing part 400, and FIGS. As shown in FIG. 12B , compression by the fixing part 400 may be released when the rotating part 500 descends and is in the rotating state 501 .

The rotation preventing member 560 may function as a sealing member preventing dust from entering between the fixing part 400 and the rotating part 500 . As examples of the sealing member, various materials such as rubber, plastic, brush, and eva-foam may be used. In this example, two elastic members having an elastic material have been exemplified as the anti-rotation member 560, but it is not necessarily limited thereto, and the material or number thereof may vary.

Referring back to FIGS. 8 and 9 , when the discharge door 220 is switched from the open position 221 to the blocked position 222, the rotating part 500 rises and moves from the rotating state 501 to the locked state 502. is converted to As the rotating part 500 rises, as shown in FIG. 12A, the first elastic member 561 is compressed and deformed in a direction perpendicular to the vertical direction by the fixing part 400, for example, in the transverse direction, as shown in FIG. 13A, The second elastic member 562 is compressed and deformed in the vertical direction by the rotation unit 500 . A first rotational frictional force is applied between the rotating part 500 and the fixing part 400 by the first elastic member 561 that is compressed and deformed, and the rotational part 500 and the rotating part 500 are connected by the second elastic member 562 that is compressed and deformed. A second rotational frictional force acts between the tops 400. Rotation of the rotating part 500 with respect to the fixed part 400 is limited by the first rotational frictional force and the second rotational frictional force. When the rotation unit 500 is in the locked state 502 , the dust collection operation of the dust collecting device 100 proceeds, so that deterioration in dust collection performance due to rotation of the rotation unit 500 can be prevented.

When the discharge door 220 is switched from the blocking position 222 to the open position 221 , the rotation unit 500 may descend and switch from the locking state 502 to the rotating state 501 . As the rotation unit 500 descends, the compression of the first elastic member 561 by the fixing unit 400 is released, as shown in FIG. 12B, and the second elastic member 562 is attached to the rotation unit 500 as shown in FIG. 13B. compression is released. Thus, since there is no rotational frictional force by the first elastic member 561 and the second elastic member 562, the rotating part 500 is in a rotatable rotational state 501.

For example, the pressing member 480 may be a spring that provides elastic force to the rotation unit 500 in the vertical direction. The pressing member 480 is installed below the mounting member 450 and can be elastically deformed in the vertical direction without rotation. However, the position and type of the pressing member 480 is not limited thereto, and may be variously modified as long as a pressing force is provided to switch the rotating part 500 from the locking state 502 to the rotating state 501. For example, as shown in FIG. 14 , the pressing member 480A may be a magnet that provides magnetic force to the rotation unit 500 in the vertical direction. The pressing member 480A may press the rotating part 500 downward by a repulsive force of magnetic force.

The inner blade 602 may be inclined with the moving direction of the air introduced through the air outlet 212 . The inner blade 602 may be inclined with the moving direction of the air discharged through the foreign matter outlet 213 .

Referring to FIGS. 25 and 26 , a second bearing structure 582A may be disposed on the rotation support 603 . The second rotation guide member 600 may be rotated about the rotation shaft 440 by the second bearing structure 582A. The rotation axis of the second rotation guide member 600 and the rotation axis AX of the rotation unit 500 are coaxially disposed.

The rotation support unit 603 may further include a ring structure 604 supported by the rotation shaft 440 when the rotation unit 500 rotates. The ring structure 604 may be spaced apart from the second bearing structure 582A in the rotation axis AX direction of the rotation shaft 440 . A ring structure 604 may be disposed on top of the second bearing structure 582A.

The ring structure 604 may include a material different from that of the rotation support 603 . For example, when the rotation support 603 is made of a plastic material, the ring structure 604 may include a metal material. An inner circumferential surface of the ring structure 604 may have a constant inner diameter. By the second bearing structure 582 and the ring structure 604, stable rotation of the rotation unit 500 can be implemented. In the embodiment, the ring structure 604 is used for stable rotation of the rotation unit 500, but is not necessarily limited thereto and may be variously modified. For example, as shown in FIG. 17 , a first bearing structure 581A may be disposed on the rotation support 603 instead of the ring structure 604 .

Referring back to FIG. 23 , as the second rotation inducing member 600 as described above is disposed inside the rotation unit 500, the air introduced through the air outlet 212 moves toward the foreign matter outlet 213. In the process, the second rotation inducing member 600 rotates, and the rotating part 500 on which the second rotation inducing member 600 is disposed rotates with respect to the fixed part 400 .

In the above-described embodiment, the second rotation inducing member 600 in which the inner blade 602 rotates around the rotation support 603 has been described. However, the shape of the second rotation inducing member 600 is not limited thereto, and may be variously modified if it is configured to rotate by air introduced through the air outlet 212 . For example, as shown in FIG. 27 , the second rotation guide member 600A may have a structure in which a plurality of inner blades 602 protrude from the coupling portion 601 without the rotation support portion 603 .

Meanwhile, in the cyclone module 300 according to the above-described embodiment, the rotating part 500 is rotated by the air flow flowing into the dust collector 100, and the first rotation guide member is formed on the outer circumferential surface of the rotating part 500. An example in which 590 is disposed and the second rotation inducing member 600 is disposed on the inner circumferential surface of the rotating unit 500 has been described. However, the configuration for rotating the rotation unit 500 of the cyclone module 300 is not limited thereto, and can be freely changed as long as it includes at least one of the first rotation induction member 590 and the second rotation induction member 600. It can be. For example, as shown in FIG. 28 , the rotating unit 500 may include a second rotation inducing member 600 disposed on an inner circumferential surface without the first rotation inducing member 590 . As another example, as shown in FIG. 3 , the rotating unit 500 may include a first rotation inducing member 590 disposed on an outer circumferential surface without the second rotation inducing member 600 .

29 is a flowchart illustrating a process of discharging foreign substances collected in the dust collecting device 100 in the cleaning device 1 according to the embodiment.

Referring to FIGS. 5 and 29 , the user first mounts the dust collector 100 of the vacuum cleaner 10 to the cleaner station 2 before or after using the vacuum cleaner 10 (S10). With the discharge door 220 of the dust collector 100 facing downward, it is docked to the docking part 3 of the cleaner station 2 .

In the process of mounting the dust collector 100 to the cleaner station 2 , the door lock 214 of the dust collector 100 is pressed by the opening guide 32 of the cleaner station 2 . As the door lock 214 is pressed, the end 2201 of the discharge door 220 and the door lock 214 are separated, and the discharge door 220 moves from the closed position 222 to the open position 221. It is converted (S20).

As the discharge door 220 is switched to the open position 221 , the dust collector 100 is connected to the collecting unit 5 through the suction passage 6 . At this time, in the cyclone module 300 of the dust collector 100, the rotating part 500 descends by the gravity of the rotating part 500 and the pressing member 480, and is in a rotatable state with respect to the fixed part 400. do.

In this state, the suction unit 4 of the cleaner station 2 operates (S30). As the suction unit 4 rotates the suction fan 153, suction force is provided to the dust collector 100. By the provided suction force, air is introduced through the air inlet 211 and the air outlet 212 , and the introduced air is discharged through the foreign matter outlet 213 .

As shown in FIG. 20 , the air introduced through the air inlet 211 forms a swirling air flow along the flow guide part 453 of the fixing part 400 . The air introduced through the air inlet 211 forms a swirling air current that moves obliquely with respect to the horizontal direction in the first cyclone 101 . Air introduced through the air inlet 211 may move between the inner circumferential surface of the dust collecting case 210 and the outer circumferential surface of the cyclone module 300 at an angle of 6 degrees to 12 degrees with respect to the horizontal direction. The air introduced through the air outlet 212 passes through the second cyclone 102 and moves to the foreign matter outlet 213 .

By the suction force provided by the cleaner station 2, a flow of air moving toward the foreign matter outlet 213 is generated in the dust collector 100. Accordingly, foreign substances collected in the dust collector 100 are primarily removed (S31).

The flow of air generated inside the dust collector 100 may rotate the rotation unit 500 . That is, the flow of air generated inside the dust collecting device 100 not only primarily removes foreign substances (S31), but also can rotate the rotating part 500 (S32).

For example, as shown in FIG. 20 , the first rotation inducing member 590 is pressed by air forming a swirling airflow, and the rotation unit 500 rotates. The rotating part 500 may have a rotational speed of a predetermined size so that foreign substances remaining inside the dust collector 100 can be removed. For example, the rotational speed of the rotating unit 500 may be 300 revolutions per minute (rpm) or more. For example, the rotational speed of the rotation unit 500 may be 500 rpm or more. The rotational speed of the rotating part 500 may be 10000 rpm or less.

In order to realize the rotational speed of the rotation unit 500, referring to FIG. 5, the cleaner station 2 may provide a predetermined suction force to the dust collector 100. For example, the suction unit 4 of the cleaner station 2 may provide suction force so that the rotation unit 500 rotates at 300 rpm or more and 10000 rpm or less. In order to implement the rotational speed of the rotating part 500, the suction unit 4 has a moving speed of the swirling airflow formed inside the dust collector 100 within a predetermined range, for example, 10 m/s to 50 m/s. Suction power can be controlled.

As the rotating part 500 rotates, foreign substances inside the dust collector 100 may be secondarily removed (S33). In other words, as the rotating unit 500 rotates, foreign substances attached to the surface of the cyclone module 300 may be separated from the surface of the cyclone module 300 by the centrifugal force and rotational torque of the rotating unit 500 . The separated foreign matter is discharged through the foreign matter outlet 213 by the suction force provided by the cleaner station 2 . Thus, foreign substances remaining inside the dust collector 100 in the process of discharging foreign substances can be reduced.

Unlike the embodiment, if the dust collecting device 100 has a structure in which foreign substances are removed only by the suction force provided by the cleaner station 2 without rotation of the rotating part 500, among the foreign substances collected in the dust collecting case 210 Some may stick to the surface of the cyclone module 300 and remain without being discharged. For example, foreign substances such as hair are caught or wrapped around the assembly gap of the cyclone module 300 or the mesh filter 512, and may remain there without being removed from the dust collecting device 100 only by the suction force of the cleaner station 2.

On the other hand, in the cleaning device 1 according to the embodiment, the rotating part 500, which is a part of the cyclone module 300, rotates, so that foreign substances remaining in the dust collector 100 are externally applied by the rotating part 500. Accordingly, it is possible to minimize foreign substances remaining inside the dust collector 100 in the process of discharging foreign substances.
