The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner in which a dust collecting capacity of a dust collecting apparatus is maximized and a manufacturing process of a main body is simplified.

In general, a vacuum cleaner is a device that sucks air containing dust by using a vacuum pressure generated by a vacuum motor mounted inside the body, and then filters the dust inside the body.

The vacuum cleaner may include a suction nozzle for sucking air containing dust, a cleaner body in communication with the suction nozzle, an extension pipe for guiding air sucked from the suction nozzle toward the cleaner body, and air passing through the extension pipe. A connector is connected to the cleaner body.

Here, a nozzle suction port having a predetermined size is formed at the bottom of the suction nozzle to allow the air containing the dust accumulated on the floor to be sucked.

On the other hand, the inside of the cleaner body, a driving unit for generating an air suction force to suck the outside air containing dust to the suction nozzle is provided.

In addition, the dust collector is detachably mounted to the cleaner body to separate and store dust. The dust collector performs a function of separating and storing dust contained in the air sucked from the suction nozzle.

In detail, the dust collecting apparatus includes a dust collecting body, an inlet for allowing air to be sucked into the dust collecting body, a cyclone portion for separating dust from the air sucked into the dust collecting body, and dust separated from the cyclone portion. The dust storage unit and a discharge port through which the dust separated from the cyclone portion is discharged.

Meanwhile, the dust stored in the lower space of the dust collecting body, that is, the dust storage unit, continuously rotates along the inner circumferential surface of the dust collecting body by the rotational flow inside the dust collecting body while the vacuum cleaner is operating.

When the operation of the vacuum cleaner is stopped, the vacuum cleaner sinks to the bottom of the dust collecting body and is stored in a low density state.

Therefore, in the conventional dust collecting apparatus, when a predetermined amount or more of dust is stored in the dust collecting unit while the vacuum cleaner is operating, the dust rises while rotating along the inner wall of the dust collecting body, and is formed in the upper space of the dust collecting body. There is a problem in that the cyclone portion is violated, and thus the unseparated dust is discharged to the discharge port by piggybacking on the discharge airflow, so that dust collection performance is reduced.

In addition, when the operation of the vacuum cleaner is stopped, the dust sinks to the bottom of the dust collecting body as it is stored in a low density state. That is, since dust inside the dust collecting body occupies a volume too large for its weight, there is an inconvenience of frequently emptying the dust collecting body in order to maintain dust collecting performance.

Therefore, in recent years, in order to improve the convenience of cleaner use, efforts have been made to maximize the capacity of dust collected in the dust collecting body and to improve dust collecting performance.

Here, the dust guide flow path 232 is guided to fall downward after the separated dust flows in the tangential direction.

Therefore, the inlet 233 of the dust guide flow path 232 is formed on the side of the first cyclone portion 230, the outlet 234 is formed on the bottom surface of the first cyclone portion 230.

On the other hand, the cover member 250 is detachably coupled to the upper side of the dust collecting body 210 as described above. That is, the cover member 250 opens and closes the first dust storage unit 214 and the second dust storage unit 216 at the same time.

Therefore, in order to discharge the dust stored in the first dust storage unit 214 and the second dust storage unit 216 to the outside, the cover member 250 to which the first cyclone unit 230 is coupled When the separation from the dust collecting body 210, the upper end of the dust collecting body 210 is completely opened. And, when the user flips the dust collecting body 210, the dust is easily discharged.

At this time, in order to empty the dust collecting body 210, since the user separates the cover member 250 from the dust collecting body 210 in a trash can or outdoors, recontamination of the room can be prevented.

In addition, a discharge hole 251 through which dust separated from the first cyclone part 230 is discharged is formed through the bottom surface of the cover member 250. The upper end of the filter member 260 having a plurality of through holes 262 of a predetermined size is coupled to the discharge hole 251.

Therefore, the air that has undergone the dust separation process in the first cyclone unit 230 is discharged through the filter member 260 to the discharge hole 251.

In addition, a flow path 253 is formed inside the cover member 250 to guide air of the first cyclone part 230 discharged from the discharge hole 251 to the first air outlet 252. . That is, the flow path 253 serves as a passage connecting the discharge hole 251 and the first air outlet 252.

On the other hand, the dust collecting body 210 is provided with a pair of pressing members (270, 280) to reduce the volume of dust stored in the first dust storage unit 214, so that the dust collecting capacity of the dust increases.

Here, the pair of pressing members 270 and 280 compress the dust by interaction with each other to reduce the volume of the dust, thereby reducing the density of the dust stored in the dust collecting body 210. The maximum dust collecting capacity of the dust collecting body 210 is increased.

Hereinafter, for convenience of description, any one of the pair of pressing members 270 and 280 is called a first pressing member 270, and the other is called a second pressing member 280.

However, in the present embodiment, the first pressing member 270 is rotatably provided inside the dust collecting body 210, and the second pressing member 280 is fixed inside the dust collecting body 210. .

Accordingly, the first pressing member 270 becomes a rotating member, and the second pressing member 280 becomes a fixing member.

In detail, the second pressing member 280 is preferably provided between the inner circumferential surface of the dust collecting body 210 and the axis of the rotating shaft 272 forming the rotation center of the first pressing member 270.

At this time, the second pressing member 280 completely or partially shields the space between the inner circumferential surface of the first dust storage unit 214 and the axis of the rotation shaft 272, and thus the first pressing member 270. When dust is pushed by), the dust is compressed together with the first pressing member 270.

To this end, one end of the second pressing member 280 is integrally formed on the inner circumferential surface of the dust collecting body 210, and the other end is fixed to the coaxial with the rotation shaft 272 of the first pressing member 270 It is preferably formed integrally with the shaft 282.

Of course, only one end of the second pressing member 280 may be integrally formed on the inner circumferential surface of the dust collecting body 210, or only the other end may be integrally formed on the fixed shaft 282. In other words, the second pressing member 280 is fixed to at least one side of the inner circumferential surface of the dust collecting body 210 and the fixed shaft 282.

However, even if one end of the second pressing member 280 is not integrally formed on the inner circumferential surface of the dust collecting body 210, one end of the second pressing member 270 is adjacent to the inner circumferential surface of the dust collecting body 210. It is preferable.

In addition, even if the other end of the second pressing member 280 is not integrally formed on the fixed shaft 282, the other end of the second pressing member 280 may be adjacent to the fixed shaft 282.

The reason is to minimize the leakage of dust pushed by the first pressing member 270 through the gap formed on the side of the second pressing member 280.

Accordingly, as the dust collecting device 200 is mounted on the dust collecting device mounting unit 170, the driven gear 410 is engaged with the driving gear 420. Detailed description thereof will be described later.

When the driven gear 410 is rotated, the inner circumferential surface of the rotating shaft 272 and the driven gear 270 may be simultaneously rotated together with the first pressing member 270 without turning. The outer circumferential surface horizontal cross-sectional shape of the gear shaft 414 of 410 is preferably polygonal.

That is, the horizontal cross-sectional shape of the rotation shaft 272 and the gear shaft 414 of the driven gear 410 is formed in a non-circular shape, so that the first pressing member 270 smoothly rotates when the driven gear 410 is rotated. It is preferred that it can be rotated.

In addition, the fastening member 278 may be fastened on the upper side of the rotating shaft 272 while the driven gear 410 is coupled to the rotating shaft 272. Therefore, not only the driven gear 410 and the rotation shaft 272 are firmly coupled, but also the phenomenon in which the driven gear 410 is lost can be further prevented.

To this end, it is preferable that a motor accommodating part (not shown) in which the driving motor is installed is formed below the bottom of the dust collecting device mounting part 170. In addition, an opening 173 for exposing a portion of the outer circumferential surface of the drive gear 420 to the dust collector mounting unit 170 is formed at a substantially central portion of the bottom of the dust collector mounting unit 130.

As the driven gear 410 is exposed to the dust collector mounting unit 170, when the dust collector 200 is mounted on the dust collector mounting unit 170, the driven gear 410 is driven by the driving gear 420. ) Is engaged.

Here, the drive motor is preferably a motor capable of forward rotation and reverse rotation. In other words, the driving motor may be a motor capable of bidirectional rotation.

Accordingly, the first pressing member 270 may rotate forward and reverse, and as the first pressing member 270 rotates forward and reverse, the first pressing member 270 may be compressed on both sides of the second pressing member 280. Dust will accumulate.

As such, in order to enable forward and reverse rotation of the drive motor, a synchronous motor may be used as the drive motor.

The synchro-motor is configured to be capable of forward and reverse rotation by the motor itself, and when the force applied to the motor is greater than or equal to a predetermined value when the motor rotates in one direction, the rotation of the motor is converted to the other direction. .

At this time, the force applied to the motor is a resistance force (torque) generated when the first pressing member 270 presses the dust, and when the resistance force reaches a set value, the rotation of the motor is directed. It is configured to be converted.

Since the synchronized motor is generally known in the motor art, a detailed description thereof will be omitted. However, it is one of the technical ideas of the present invention to enable forward and reverse rotation of the driving motor by the synchro motor.

In addition, even when the first pressing member 270 rotates to reach a peak that can no longer rotate while compressing the dust, the first pressing member 270 may continuously press the dust for a predetermined time. Do.

Here, the peak that the first pressing member 270 cannot rotate refers to when the resistance reaches a set value.

When the resistance reaches the set value, the power for rotating the first pressing member 270, that is, the power applied to the driving motor is cut off for a predetermined time, so that the first pressing member 270 is stopped. The dust is compressed in the stopped state, and when the predetermined time passes, the first pressurizing member 270 is moved by applying power to the driving motor again.

At this time, since the resistance time when the power applied to the drive motor reaches the set value, when the drive motor is driven again, the rotation direction of the drive motor will be the opposite direction before the power cut off.

In addition, the drive motor preferably continuously rotates the first pressing member 270 forward / reversely at the same angular speed so that dust can be easily compressed.

In addition, when a dust or more of a predetermined amount of dust is collected inside the dust collecting body 210, it is preferable to display the emptying time of the dust collecting body 210 to the user in order to prevent deterioration of dust collection performance and overload of the motor. .

To this end, a display unit (not shown) is provided on the cleaner main body 100, the dust collecting device 200, or the handle (not shown), so that a predetermined amount or more of dust is stored in the dust collecting body 210. 1 When the rotation range of the pressing member 270 is less than a predetermined angle, the emptying time of the dust collecting body 210 is displayed to the user.

On the other hand, the lower side of the dust collecting body 210 is formed with a guide rib 290 for guiding the mounting of the dust collecting device 200 to the cleaner body 100, the dust collector mounting portion 170, the guide rib ( An insertion groove 172 into which the 290 is inserted is formed.

The guide rib 290 is provided in a "C" shape on the outer side of the driven gear 410 to surround a portion of the driven gear 410. Accordingly, the guide rib 290 also serves to protect the driven gear 410.

Here, when the dust collecting device 200 is mounted on the dust collecting unit mounting portion, the driven gear 410 and the driving gear 420 should be coupled to each other. For this reason, the guide rib 290 is formed so that a portion of the driven gear 410 is exposed to the outside.

In addition, the dust collecting device mounting unit 170 has a removal prevention groove 174 which prevents the dust collecting device 200 from being removed to the front of the cleaner body 10 in a state where the dust collecting device 200 is seated on the dust collecting device mounting unit 170. And a stripping prevention protrusion 294 inserted into the stripping preventing groove in the guide rib.

Therefore, even when the dust collecting device 200 is pulled forward by the dust collecting device 200 seated on the dust collecting device mounting portion 170 by the stripping prevention groove 174, the anti-separation protrusion 294 Is caught by the removal preventing groove 174 to prevent the removal of the dust collector 200.

In addition, the dust collecting device mounting portion 170 is formed with a seating portion 176 for guiding the mounting of the guide rib 290, the seating groove of the shape corresponding to the seating portion 290 in the guide rib 290. 295 is formed.

The dust collecting device 200 may be easily mounted to the dust collecting device mounting unit 170 by the seating unit 290 and the mounting groove 295, and the dust collecting device 200 may be mounted on the dust collecting device mounting unit ( Rocking is prevented in the state of mounting at 170).

Hereinafter, the operation of the vacuum cleaner constituting the above-described configuration will be described.

First, when power is applied to the suction motor of the vacuum cleaner 10, suction force is generated by the suction motor, and air containing dust is sucked into the suction nozzle by the suction force.

In addition, the air sucked through the suction nozzle is introduced into the cleaner body 100 through the main body suction part 110, and the introduced air is introduced into the dust collector 200 through a predetermined flow path.

In detail, the dust-containing air is sucked in the tangential direction of the first cyclone part 230 through the first air inlet 212 of the dust collecting body 210. In addition, the sucked air falls while turning along the inner circumferential surface of the first cyclone unit 230, and in this process, the air and the dust are separated from each other while receiving different centrifugal forces by the weight difference.

In addition, the dust is separated air is filtered through the through hole 262 of the filter member 260 and then discharged to the outside of the dust collector 200 through the discharge hole 251 and the first air outlet 252. do.

On the other hand, the separated dust is introduced into the dust guide flow path 232 in the tangential direction in the process of turning along the inner circumferential surface of the first cyclone portion 230.

In addition, the dust introduced into the dust guide flow path 232 flows along the outer circumferential surface of the first cyclone part 230 by changing the flow direction inside the dust guide flow path 232, and the discharge port 234. Falling downward through the first dust storage unit 214 is stored.

Meanwhile, the air discharged through the first air outlet 252 is introduced into the cleaner body 100. In addition, the air introduced into the cleaner body 100 is introduced into the second cyclone unit 300 through the connection passage 114.

The air is tangentially guided to the inner wall of the second cyclone part 300 through the second air inlet 302 connected to the end of the connection flow passage 114, and the dust is separated again while flowing therein. do.

In addition, the air from which the dust is separated again flows into the cleaner body 100. In addition, the air introduced into the cleaner body 100 is discharged to the outside through the body discharge part of the rear side of the cleaner body 100 through the suction motor.

On the other hand, the separated dust is introduced into the dust collector 200 through the dust inlet 254, and finally stored in the second dust storage unit 216.

As the dust in the air is separated and dust is stored in the dust storage unit as described above, the pair of pressing members 270 and 280 compress the dust stored in the first dust storage unit 114.

In detail, when the drive motor is rotated in one direction, the rotational power of the drive motor is transmitted to the driven gear 410 through the drive gear 420, so that the driven gear 410 is rotated in one direction. In addition, the rotation shaft 272 and the first pressing member 270 are rotated by the rotation of the driven gear 410.

As described above, when the first pressing member 270 is rotated in one direction, the first pressing member 270 removes dust between the first pressing member 270 and the second pressing member 280 from the second pressing member 270. The dust is compressed by pushing toward one side of the pressing member 280. The rotation of the first pressing member 270 is continued until the resistance generated in the process of pressing the dust reaches a set value.

When the resistance reaches a predetermined value or more, the power applied to the driving motor is cut off and the first pressing member 270 is stopped in the state in which the dust is compressed.

Then, the first pressing member 270 presses the dust for a predetermined time at the stop position. When the predetermined time elapses, the driving motor is driven again to rotate the first pressing member 270.

Here, since the first pressing member 270 is stopped in the state where the resistance force reaches a set value, the rotation direction is converted and rotated in the other direction.

In addition, when the first pressing member 270 is rotated in the other direction, the first pressing member 270 presses the dust between the first pressing member 270 and the second pressing member 280 to the second pressing member. The dust is compressed by pushing toward the other side of the member 280.

When the resistance applied to the first pressing member 270 reaches a predetermined value or more during the rotation of the first pressing member 270, the power applied to the driving motor is cut off, thereby the first pressing member 270. ) Is stopped while the dust is compressed.

Then, the first pressing member 270 presses the dust for a predetermined time at the stop position. When the predetermined time passes, the driving motor is driven again to rotate the first pressing member 270 in the opposite direction.

As described above, the compressing action is repeatedly performed until the rotation range of the first pressing member 270 is equal to or less than a predetermined angle. When the cleaner is stopped by the user in this process, the dust compressing process is terminated.

Meanwhile, in order to empty the dust stored in the dust collecting body 210, the user separates the dust collecting device 200 from the cleaner body 100.

In addition, the cover member 250 to which the first cyclone unit 230 is coupled is separated from the dust collector 200. Then, the dust collecting body 210 is reversed to empty the dust.

According to the present invention, as the coupling portion having a shape corresponding to the connection hose is formed in the main body suction part and the air outlet port, the connection hose can be coupled to the main body suction part and the air outlet port by a rotation operation. Therefore, the coupling process and the cost of the connection hose are reduced.

In addition, since the dust stored in the dust collector is compressed by a pair of pressing members to minimize the volume thereof, there is an effect of maximizing the dust collection capacity of the dust stored in the dust collector.

In addition, as the dust collecting capacity of the dust collecting device is maximized by the compression action of the pair of pressing members, the inconvenience that the user frequently needs to empty the dust stored in the dust collecting device is removed.

In addition, as the dust collected in the dust collecting apparatus maintains the compressed state even when the operation of the vacuum cleaner is stopped, the dust stored in the dust collecting unit is easily discharged to the outside of the dust collecting apparatus when the dust is empty.
