A power transmission unit 300 for transmitting and a guide device 400 for selectively transmitting the rotational force of the moving wheel 140 to the power transmission unit 300 is included. Here, the power transmission unit 300 and the guide device 400 allows the moving wheel 140 and the first pressing member 250 to be indirectly connected, and thus may be referred to as a "connection device."

In addition, the power transmission unit 300 includes a driving gear 310 coupled with the guide device 400, an intermediate gear 320 rotated by the driving gear 310, and the first pressing member 250. And a driven gear 330 that is selectively engaged with the intermediate gear 320. Here, in terms of the position of each gear, the drive gear 310 and the intermediate gear 320 is provided in the main body 100 may be called a first power transmission unit, the driven gear 330 is Since the dust collector 200 is provided, it may be referred to as a second power transmission unit.

The guide device 400 is formed in a shape corresponding to the first guide part 410 and the first guide part 410 that are coupled to the moving wheel and rotate together with the moving wheel, and the driving gear A second guide portion 420 coupled to the 310 is included.

In detail, the moving wheel 140 is coupled to the wheel coupling portion 114 formed on both sides of the upper body 110. When the moving wheel 140 is coupled to the wheel coupling unit 114, the shaft 142 of the moving wheel 140 penetrates the wheel coupling unit 114. In addition, the locking protrusion 144 is formed on the shaft 142 of the movable wheel 114 to maintain the coupled state of the movable wheel 140 and the wheel coupling part 114, and the wheel coupling part ( 114, the protrusion insertion groove 116 into which the locking protrusion 144 is inserted is formed.

At this time, when the moving wheel 140 is rotated, the locking projection 144 is also rotated, the projection insertion groove 116 is formed in a shape corresponding to the rotational trajectory of the locking projection 144.

The first guide part 410 is coupled to the shaft 142 of the moving wheel 140 passing through the wheel coupling part 114. The second guide part 420 is in close contact with one side of the first guide part 410.

In detail, the first guide part 410 is formed by extending from the first body part 412 and the first body part 412 and coupled to the shaft 142 of the moving wheel 140. One rotating shaft 414 is included. In addition, the first rotation shaft 414 is movably coupled to the shaft 142 of the movement wheel 140 in the axial direction.

In addition, the second guide part 420 is formed to extend from the second body part 422 and the second body part 422 in close contact with the first body part 412, and the driving gear ( A second rotation shaft 424 to which the 310 is coupled is included.

The center of rotation of the first guide part 410 and the second guide part 420 are provided on the same line. That is, the first guide part 410, the second guide part 420, and the moving wheel 140 have the same center of rotation.

In addition, a second elastic member 450 is provided between the first body portion 412 and the wheel coupling portion 114. That is, the first guide part 410 is supported by the second elastic member 450. In addition, the elastic force of the second elastic member 450 has a smaller value than the elastic force of the first elastic member 270.

In addition, the unevenness 413 is formed in the first body part 412, and the first body is formed on the surface of the second body part 412 facing the unevenness 413 of the first guide part 412. Unevenness 423 having a shape corresponding to the unevenness 413 of the portion 412 is formed.

Therefore, when the unevenness 414 of the first guide part 410 and the unevenness 423 of the second guide part 420 are engaged with each other, the first guide part 410 together with the moving wheel 140. When the rotation, the second guide portion 420 is rotated together.

Here, the rotation shaft 142 of the moving wheel 140 in order to prevent the phenomenon that the moving wheel 140 is idle against the first guide portion 410 when the moving wheel 140 is rotated. And, the vertical axis of the inner circumferential surface of the rotating shaft 414 of the first guide portion 410, as shown in Figure 5, preferably formed in a polygon.

At this time, the recesses and protrusions 413 and 423 are held in engagement with each other by the second elastic member 450.

That is, since the second guide member 410 elastically supports the first guide part 410 toward the second guide part 420, the first guide part 410 is the second guide part ( The 420 is pushed toward the side, so that the unevenness 413 of the first guide part 410 and the unevenness 423 of the second guide part 420 may be engaged.

Here, the concave-convex portions 413 and 423 are formed to have rounded surfaces that are combined with each other so that the concave-convex portion 413 of the first guide portion 410 may cross the concave-convex portion 423 of the second guide portion 420. This is preferred.

In detail, when the uneven states 413 and 423 are held in engagement, when the first pressing member 250 is completely moved toward the second pressing member 260 by the rotation of the moving wheel 140. The first pressing member 250 may not be rotated any more. When the moving wheel 140 is continuously rotated in this state, the first pressing member 250, the power transmission unit 300, or the guide unit ( Damage to 410 and 420 may occur.

Therefore, in the present embodiment, as the combined surfaces of the unevenness 413 and 423 are formed to be rounded, the movable wheel 140 is rotated in a state in which the first pressing member 250 can no longer rotate. In this case, the unevenness 413 of the first guide part 410 passes over the unevenness 423 of the second guide part 410, and thus, the first pressing member 250, the power transmission part 300, or the like. Damage to the guide parts 410 and 420 can be prevented.

Of course, the unevenness 413 of the first guide part 410 passes over the unevenness 423 of the second guide part 420 so that the first guide part 410 has a shaft of the moving wheel 140. This is because it is movable in the axial direction with respect to 142.

In addition, when the unevenness 413 of the first guide part 410 passes over the unevenness 423 of the second guide part 420, the second elastic member 250 may be repeatedly compressed and extended. .

In the above description, the unevenness 413 of the first guide part 410 exceeds the unevenness 423 of the second guide part 420. The unevenness 423 may cross over the unevenness 413 of the first guide part 410. Detailed description thereof will be described later.

On the other hand, the drive gear 310 is coupled to the second rotation shaft 424 is rotated in the vertical direction. That is, since the shaft 142 of the moving wheel 140 is placed in the horizontal direction and the second rotation axis 424 is provided on the same line as the shaft 142 of the moving wheel 140 as shown in FIG. 4. The drive gear 140 is rotated in the vertical direction.

In addition, the intermediate gear 320 meshes with the driving gear 310 to change the vertical rotation of the driving gear 410 into a horizontal rotational motion. To this end, bevel gears may be used for the intermediate gear 320 and the driving gear 310.

In addition, the driven gear 330 is coupled to the lower side of the dust collecting body 210 as described above. Thus, the driven gear 330 is exposed to the outside of the dust collecting body 210.

At this time, the dust collecting device mounting portion 120 is formed with a guide groove 122 for guiding the mounting of the driven gear 200 when the dust collecting device 200 is mounted. In addition, the intermediate gear 320 is partially exposed to the guide groove 122 so that the driven gear 330 and the intermediate gear 320 mesh with each other. To this end, an opening 123 is formed in the dust collector mounting part 120 to expose a portion of the intermediate gear 320.

Therefore, when the dust collecting device 200 is mounted on the dust collecting device mounting unit 120, the driven gear 330 and the intermediate gear 320 are engaged.

Hereinafter, the operation of the dust collector and the dust compression process in the dust collector will be described.

6 is a view illustrating a process in which the rotational force of the moving wheel is transmitted to the driven gear according to the present embodiment, and FIG. 7 illustrates a state in which the first pressing member is rotated in one direction by the moving wheel according to the present embodiment. Drawing.

6 and 7, in order to perform cleaning, first, the dust collecting device 200 is mounted on the dust collecting device mounting part 120. Then, the driven gear 330 is engaged with the intermediate gear 320 so that the first pressing member 250 is rotatable by the moving wheel 140.

When the suction motor provided to the cleaner body 10 is turned on and suction power is generated, air containing dust is introduced into the dust collecting body 210 through the suction port 212 by the suction force generated.

In addition, the air sucked into the dust collecting body 210 falls while turning along the inner circumferential surface of the dust collecting body 210, and in this process, the air and the dust are separated from each other while receiving different centrifugal forces due to the weight difference. Is done.

Then, the dust is separated air is filtered through the through-hole 232 of the filter member 230, is discharged from the dust collecting body 210 through the discharge hole 222, from the dust collecting body 210 The discharged air flows into the cleaner body 10 along the discharge guide 224.

On the other hand, the separated dust is dropped downward in the process of turning along the inner circumferential surface of the dust collecting body 210 is stored in the dust storage unit 211.

At this time, the user advances in the process of moving the suction nozzle back and forth, and thus the cleaner body 10 is moved forward by the moving wheel 140. In addition, the first pressing member 270 is rotated by the front rotation of the movable wheel 140 to compress the dust.

Here, when the directional meaning in the description of the present embodiment will be described, "turning forward" means the same direction as the direction in which the moving wheel 140 is rotated in order to advance the cleaner body 10 and To rotate backward means the same direction as the direction in which the moving wheel rotates in order for the cleaner body 10 to reverse.

In addition, rotation in a clockwise or counterclockwise direction means rotation in a clockwise or counterclockwise direction when viewed from above the dust collecting apparatus.

In detail, in the state where the cleaner main body 10 is stopped before the cleaning is performed, the first pressing member 250 may be formed by the left side surface of the second pressing member 260 by the elastic force of the first elastic member 270. 260a) to remain at a standstill. Hereinafter, the position when the first pressing member 250 can no longer be rotated at a portion adjacent to the left surface 260a of the second pressing member is referred to as a “first reference position”.

As described above, when the moving wheel 140 rotates forward while the first pressing member 250 is in the first reference position, the first guide coupled to the shaft 142 of the moving wheel 140. The part 410 is rotated forward. When the first guide part 410 is rotated forward, the second guide part 420 and the second rotation axis of the second guide part 420 that are in close contact with the first guide part 410 ( Drive gear 310 coupled to 424 is rotated forward.

In this case, as described above, the first guide part 410 is maintained in close contact with the second guide part 420 by the second elastic member 450.

When the driving gear 310 is rotated forward, the intermediate gear 320 is rotated in the clockwise direction, and when the intermediate gear 320 is rotated in the clockwise direction, the driven gear 330 is counterclockwise. Is rotated. When the driven gear 330 rotates in the counterclockwise direction, the first pressing member 250 is finally rotated in the counterclockwise direction.

Then, the first pressing member 250 positioned adjacent to the left side 260a of the second pressing member 260 rotates toward the right side 260b of the second pressing member 260. Then, dust is compressed between one side surface of the first pressing member 250 and the right side surface 260b of the second pressing member 260.

Here, since the rotational force of the moving wheel 140 is greater than the elastic force of the first elastic member 270, the rotation of the first pressing member 250 is possible.

On the other hand, in a state in which the first pressing member 250 completely compresses the dust, the first pressing member 250 is no longer rotated by the resistive force acting as the first pressing member 250.

Hereinafter, the first pressing member 250 is rotated counterclockwise by the moving wheel 140 at the first reference position so that the first pressing member 250 can no longer rotate toward the right side 260b of the second pressing member 260. The position at the time is referred to as a "second reference position" and at a rotational speed or second reference position of the moving wheel 140 for moving the first pressing member 250 from the first reference position to the second reference position. The rotational speed of the moving wheel 140 to reach the first reference position is referred to as "limit rotational speed".

Then, the first reference position and the second reference position is changed according to the amount of dust stored in the dust collecting body 210, and the limit rotational speed, when the dust stored in the dust collecting body 210 is small Larger and smaller as the amount of dust stored in the dust collecting body 210 increases.

In this state, when the first pressing member 250 is stopped at the second reference position, when the moving wheel 140 rotates further forward, that is, the moving wheel 240 rotates beyond the limit rotation speed. When the first guide portion 410 is rotated forward.

However, since the first pressing member 250 is maintained in a stopped state due to the resistive force acting on the first pressing member 250, the power transmission unit 300 and the second guide unit 420 also rotate. You will not be able to.

In this case, the elastic force of the second elastic member 450 supporting the first guide part 410 is smaller than the rotational force of the moving wheel 140 and the resistance force acting on the first pressing member 250.

Accordingly, the first guide part 410 is rotated together with the moving wheel 140, but receives a resistance force from the second guide part 420, so that the second elastic member 450 is contracted to the first guide part 410. The unevenness 413 of the guide part 410 passes over the unevenness 423 of the second guide part 423.

Here, since the elastic force of the first elastic member 270 is greater than the elastic force of the second elastic member 450, the unevenness 413 of the first guide part 410 may be defined by the second guide part 420. In the course of riding over the unevenness 423, the first pressing member 250 is rotated in the clockwise direction by the elastic force of the first elastic member 270, so that the left surface 260a of the second pressing member 260 is rotated. To the side to return to the first reference position.

That is, when the rotational speed of the moving wheel 140 is further rotated beyond the limit rotational speed, the first pressing member 250 returns to the first reference position from the second reference position.

8 is a view illustrating an operation state of the guide unit and the power transmission unit in the state in which the moving wheel according to the present embodiment is stopped, and FIG. The figure shows how it is rotated.

8 and 9, the first pressing member 250 is rotated toward the right side surface 260b of the second pressing member 260 by the rotation of the moving wheel 140 to compress dust. That is, in a state in which the first pressing member 250 is in the second reference position or the first pressing member 250 is moving toward the right side surface 260b of the second pressing member 260, the When the moving wheel 140 is stopped, since the elastic force of the first elastic member 270 is greater than the elastic force of the second elastic member 450, the first pressing member 250 is the first elastic member 270. Rotate counterclockwise by elastic force.

When the first pressing member 250 is rotated in the clockwise direction, dust is compressed between the other side surface of the second pressing member 250 and the left surface 260a of the second pressing member 260. The first pressing member 250 is stopped at the first reference position.

When the first pressing member 250 is rotated in the clockwise direction, the driven gear 330 is rotated in the clockwise direction, and the intermediate gear 320 is rotated in the counterclockwise direction. In addition, when the intermediate gear 320 is rotated counterclockwise, the second guide part 420 is rotated backward.

At this time, the elastic force of the first elastic member 270 and the rotational force of the second guide portion 420 is the same, the rotational force of the second guide portion 420 is smaller than the static friction force of the moving wheel 140 It is greater than the elastic force of the second elastic member 450. Therefore, the second elastic member 450 is contracted by the rotation of the second guide part 420.

Then, the unevenness 423 of the second guide part 420 passes over the unevenness 413 of the first guide part 410, and the second guide part 250 rotates backward.

Meanwhile, the cleaner main body 10 may be stopped while the cleaning is being performed. In the state where the cleaner main body 10 is stopped, the first pressing member 250 may have a first reference position as described above. Stays at.

In this state, when the moving wheel 140 is rotated to the rear, the first guide portion 410 is rotated to the rear.

However, since the first pressing member 250 can no longer rotate counterclockwise from the first reference position, the power transmission unit 300 and the second guide unit 420 also cannot rotate.

In this case, the elastic force of the second elastic member 450 supporting the first guide part 410 is smaller than the rotational force of the moving wheel 140 and the resistance force acting on the first pressing member 250.

Therefore, although the first guide part 410 is rotated backward with the moving wheel 140 but receives a resistance force from the second guide part 420, the second elastic member 450 is contracted and the The unevenness 413 of the first guide part 410 passes over the unevenness 423 of the second guide part 423. In addition, the first pressing member 250 maintains a stopped state.

According to the embodiment as proposed, since the dust stored in the dust storage unit is compressed, there is an effect that the capacity of the dust stored in the dust collector is maximized.

In addition, as the dust collecting capacity of the dust collecting device is maximized by the compression action of the dust, the user has to remove the trouble of frequently emptying the dust stored in the dust collecting device.

In addition, since the dust is kept in a compressed state in the dust collector, there is an effect that the scattering of dust in the process of emptying the dust is prevented.

In addition, since the pressing member is rotated by the rotational force of the moving wheel to automatically compress the dust, the user is required to operate the pressing member, thereby reducing the need for a motor for automatically driving the pressing member. have.
