The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner to increase the dust collecting capacity of the dust collecting unit.

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

Such a vacuum cleaner may be distinguished by a canister method in which a nozzle part, which is a large suction port, is provided separately from the main body and connected by a connecting pipe, and an upright method in which the nozzle part is integrally formed with the main body.

On the other hand, the dust collecting unit mounted on the cyclone vacuum cleaner uses a cyclone principle, so that foreign matter included in the sucked air and rotated together is separated and collected from the air, and the air from which the foreign matter is removed is discharged to the outside of the cleaner. One device.

In detail, the cyclone dust collecting unit includes a dust collecting body, an inlet for allowing air to be sucked into the dust collecting body, a cyclone portion for separating foreign matter from the air sucked into the dust collecting body, and a foreign matter separated from the cyclone portion. The foreign matter storage unit, and the outlet for discharging the air is separated foreign matter from the cyclone unit.

On the other hand, the foreign body stored in the lower space of the dust collecting body, that is, the foreign matter 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 unit, when a predetermined amount or more of foreign matter is collected inside the dust collecting unit while the vacuum cleaner is in operation, the foreign matter rises while rotating along the inner wall of the dust collecting container, 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 foreign material sinks to the bottom of the dust collecting body as it is stored in a low density state. That is, since the foreign material in the dust collecting body occupies a volume too large for its weight, there was an inconvenience of frequently emptying the dust collecting body in order to maintain the dust collecting performance.

Therefore, in recent years, in order to improve the convenience of using a cleaner, efforts have been made to maximize the dust collecting capacity of the foreign matter collected in the dust collecting body and at the same time improve the dust collecting performance.

The present invention has been proposed to solve the above problems, and an object of the present invention is to propose a vacuum cleaner to increase the foreign matter collecting capacity of the dust collecting unit.

In addition, an object of the present invention is to propose a vacuum cleaner in which compression of a foreign material provided in a dust collecting unit is automatically performed.

Vacuum cleaner according to the present invention for achieving the object as described above is a dust collecting unit is stored; A cleaner body to which the dust collecting unit is detachably mounted; A pressing plate movably provided in the dust collecting unit to compress the foreign matter; A drive motor for moving the pressure plate; And a display unit configured to display when the compressed foreign material is emptied when the movement range of the pressure plate is within a predetermined range.

According to the present invention as proposed, since the foreign matter stored in the dust collecting unit is compressed by the pressurizing device to minimize the volume, there is an effect that the dust collecting capacity of the foreign matter stored in the dust collecting unit is maximized.

Hereinafter, with reference to the drawings will be described a specific embodiment of the present invention.

Referring to FIG. 1, the vacuum cleaner according to the spirit of the present invention includes a cleaner main body 100 having a suction force generating means therein, and a dust collecting unit 200 for separating and storing foreign matter contained in the sucked air. It is composed.

Although not shown, a suction nozzle for sucking air containing foreign substances and a connection pipe for connecting the suction nozzle to the cleaner body 100 are further included.

In the present embodiment, the basic configuration of the suction nozzle and the connection pipe is the same as the conventional description thereof will be omitted.

In detail, a main body suction part 110 is formed at the front lower end of the cleaner main body 100 to suck air containing foreign matter sucked from the suction nozzle (not shown).

In addition, one side surface of the cleaner body 100 is provided with a body discharge part 120 through which the air from which the foreign matter is separated is discharged to the outside.

On the other hand, the dust collecting unit 200 includes a foreign matter separating portion 210 for separating the foreign matter contained in the air to be sucked, and a dust collecting container 220 for storing the foreign matter separated from the foreign matter separating portion.

Here, the foreign matter separating unit 210 includes a cyclone unit 211 for separating the foreign matter contained in the air sucked by the cyclone principle, that is, the difference between the centrifugal force of the air and the foreign matter. Therefore, the foreign matter separated by the cyclone portion 211 is stored in the dust collecting container 220.

On the other hand, the dust collecting unit 200 is preferably configured to maximize the dust collecting capacity of the foreign matter stored therein. To this end, the dust collecting unit 200 is preferably configured to reduce the volume of the foreign matter stored in the dust collecting container 220 is added.

Hereinafter, referring to FIGS. 2 to 5, a vacuum cleaner including a dust collecting unit according to the present invention, in which the dust collecting capacity of the foreign material is maximized, will be described.

2 is a perspective view showing a dust collecting unit mounting portion and a dust collecting unit applied to the vacuum cleaner separately, FIG. 3 is a sectional perspective view of the dust collecting unit, FIG. 4 is an enlarged view of a portion A of FIG. 3, and FIG. It is a perspective view which shows the coupling relationship of the drive unit and the dust collection unit provided for the compression of the foreign material stored in the dust collection unit.

2 to 5, the dust collecting unit 200 according to the spirit of the present invention is detachably mounted to the cleaner body 100.

In addition, the cleaner body 100 is provided with a dust collecting unit mounting unit 130 for mounting the dust collecting unit.

In addition, the dust collecting unit 200 is provided with a pair of pressing plates 310 and 320 to reduce the volume of the foreign matter stored in the dust collecting container 220 to increase the dust collecting capacity of the foreign matter.

Here, the pair of pressure plates (310, 320), by compressing the foreign material by interaction with each other to reduce the volume of the foreign material, thereby reducing the density of the foreign material stored in the dust collecting container 220, The maximum dust collecting capacity of the dust collecting container 220 is increased.

Hereinafter, for convenience of description, any one of the pair of pressure plates 310 and 320 is called a first pressure plate 310 and the other is called a second pressure plate 320.

In the present embodiment, at least one of the pair of pressure plates 310 and 320 is provided to be movable inside the dust collecting container 220, so that the foreign material is compressed between the pair of pressure plates 310 and 320. Perform the action.

That is, when the first pressing plate 310 and the second pressing plate 320 are rotatably provided in the dust collecting container 220, the first pressing plate 310 and the second pressing plate 320 face each other. While rotating, the distance between one side of the first pressing plate 310 and one side of the second pressing plate 320 opposite to one side of the first pressing plate 310 is narrowed, and thus the first The foreign material located between the first pressing plate 310 and the second pressing plate 320 is compressed.

However, in the present embodiment, the first pressing plate 310 is rotatably provided inside the dust collecting container 220, and the second pressing plate 320 is fixed inside the dust collecting container 220.

Therefore, the first pressure plate 310 is a rotating plate, the second pressure plate 320 is a fixed plate.

In addition, a foreign matter storage unit 221 is formed in the dust collecting container 320 to form a space in which foreign matter is stored. In addition, the foreign material storage unit 221 is formed so as to surround a virtual trajectory drawn while the free end 311 of the first pressing plate 310 rotates.

In detail, the second pressing plate 320 is preferably provided between the inner circumferential surface of the foreign matter storage unit 221 and the axis of the rotating shaft 312 forming the rotation center of the first pressing plate 310.

That is, the second pressing plate 320 is provided on a surface connecting the axis of the rotary shaft 312 and the inner circumferential surface of the foreign matter storage portion 221. At this time, the second pressing plate 320 completely or partially shields the space between the inner circumferential surface of the foreign matter storage unit 221 and the axis of the rotary shaft 312, and the foreign material by the first pressing plate 310. When pushed in, the foreign material is compressed together with the first pressing plate 310.

To this end, one end 321 of the second pressing plate 320 is integrally formed on the inner circumferential surface of the foreign matter storage unit 221, the other end is provided coaxially with the rotation shaft 312 of the first pressing plate 310. It is preferably formed integrally with the fixed shaft 322.

Of course, only one end of the second pressing plate 320 may be integrally formed on the inner circumferential surface of the foreign matter storage unit 221 or only the other end may be integrally formed on the fixed shaft 322. In other words, the second pressing plate 320 is fixed to at least one side of the inner circumferential surface of the foreign matter storage unit 221 and the fixed shaft 322.

However, even if one end of the second pressing plate 320 is not integrally formed on the inner circumferential surface of the foreign material storage unit 221, one end of the second pressing plate 320 may be adjacent to the inner circumferential surface of the foreign material storage unit 221. It is preferable.

Further, even if the other end of the second pressure plate 320 is not integrally connected to the fixed shaft 322, the other end of the second pressure plate 320 may be adjacent to the fixed shaft 322.

The reason is to minimize the leakage of dust pushed by the first pressing plate 310 through the gap formed on the side of the second pressing plate 320.

The first pressing plate 310 and the second pressing plate 320 configured as described above are preferably composed of a square plate. In addition, the rotation shaft 312 of the first pressing plate 310 is preferably provided coaxially with the axis forming the center of the foreign material storage unit 221.

On the other hand, the fixed shaft 322 is protruded inwardly from one end of the foreign matter storage portion 221, the inside of the fixed shaft 322 is a hollow penetrating in the axial direction for the assembly of the rotating shaft 312 Is formed. A predetermined portion of the rotating shaft 312 is inserted into the hollow from the upper side of the fixed shaft 322.

In addition to the above configuration, the vacuum cleaner according to the present invention further includes a driving device 400 connected to the rotation shaft 312 of the first pressing plate 310 to rotate the first pressing plate 310.

Hereinafter, a coupling relationship between the dust collecting unit 200 and the driving device 400 will be described in detail with reference to FIGS. 4 and 5.

The driving unit 400 includes power transmission units 410 and 420 for rotating the first pressure plate 310 and a driving motor 430 for rotating the power transmission units 410 and 420.

In detail, the power transmission units 410 and 420 may be driven gears 410 (which may be referred to as second power transmission units) coupled to the rotation shaft 312 of the first pressure plate 310 and the driven gears 410. A drive gear 420 (also referred to as a first power transmission portion) for transmitting power is included.

In addition, the drive gear 420 is coupled to the rotation shaft of the drive motor 430 is rotated by the drive motor 430.

Accordingly, when the driving motor 430 is rotated, the driving gear 420 coupled with the driving motor 430 is rotated, and the rotational force of the driving motor 430 is driven by the driving gear 420. The driven gear 410 is rotated by being transmitted to the gear 410, and finally, the first pressing plate 310 is rotated by the rotation of the driven gear 410.

Here, the drive motor 430 is provided on the lower side of the dust collecting unit mounting unit 130, the drive gear 420 is coupled to the rotary shaft of the drive motor 430, the bottom surface of the dust collecting unit mounting unit 130 Is provided.

A portion of the outer circumferential surface of the drive gear 420 is exposed to the outside from the bottom of the dust collecting unit mounting unit 130. 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 unit mounting part 130, and the center of the bottom of the dust collecting unit mounting part 130 is the driving gear 420. An opening for exposing a portion of the outer circumferential surface to the outside is formed.

On the other hand, the rotating shaft 312 of the first pressing plate 310 is inserted into the hollow of the fixed shaft 322 from the upper side of the fixed shaft 322, the driven gear 410 of the dust collecting container 220 It is inserted into the hollow of the fixed shaft 322 from the lower end is coupled to the rotating shaft 312.

In addition, the rotating shaft 312 is formed with a stepped portion 312c supported by the upper end of the fixed shaft 322, the image of the first pressing plate 310 is combined with respect to the stepped portion 312c. The sub shaft 312a and the driven gear 410 is divided into a lower shaft 312b.

Here, a groove 312d into which the gear shaft of the driven gear 410 is inserted is formed in the lower shaft 312b so that the lower shaft 312b and the driven gear 410 may be coupled to each other.

Here, the groove 312d may be formed in various shapes such as a circle and a quadrangle, and the gear shaft of the driven gear 410 is formed in a shape corresponding to the groove 312d.

Therefore, when the driven gear 410 is coupled to the rotary shaft 312 as described above, the driven gear 410 is exposed to the outside of the dust collecting container 220.

As the driven gear 410 is exposed to the outside of the dust collecting container 220, when the dust collecting unit 200 is mounted on the dust collecting unit mounting unit 130, the driven gear 410 is driven by the driving gear ( 420).

On the other hand, the drive motor 430 is preferably a motor capable of forward rotation and reverse rotation. In other words, the driving motor 430 may be a motor capable of bidirectional rotation.

Accordingly, as shown in FIGS. 6 and 7, the first press plate 310 may rotate forward and reverse, and as the first press plate 310 rotates forward and reverse, the second press plate ( Compressed foreign materials are accumulated on both sides of the 320).

As such, in order to enable forward and reverse rotation of the driving motor 430, a synchronous motor may be used as the driving motor 430.

The synchro-motor is configured to enable 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. do.

At this time, the force applied to the motor is a resistance force (torque: torque) generated when the first pressure plate 310 presses the foreign material. When the resistance force reaches a set value, the direction of rotation of the motor is changed. 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 430 by the synchro motor.

In addition, even when the first pressing plate 310 is rotated to reach a peak that can no longer rotate while compressing the foreign material, it is preferable that the first pressing plate 310 continuously presses the foreign material for a predetermined time.

Here, the peak that the first pressure plate 310 cannot rotate refers to a case where the resistance force reaches a set value.

When the resistance reaches the set value, the power for rotating the first pressing plate 310, that is, the power applied to the driving motor 430 is cut off for a predetermined time and the first pressing plate 310 is removed. In this stopped state, the foreign material is compressed, and after a predetermined time, power is again applied to the driving motor 430 to allow the first pressing plate 310 to be moved.

At this time, since the resistance time when the power applied to the drive motor 430 reaches the set value, when the drive motor 430 is driven again, the direction of rotation of the drive motor 430 is It will be in the opposite direction as before power off.

In addition, the drive motor 430 preferably continuously rotates the first pressure plate 310 at the same angular speed so as to easily compress the foreign material.

In addition, when the foreign matter is collected in a predetermined amount or more inside the dust collecting container 220, in order to prevent deterioration of dust collection performance and overload of the motor, it is preferable to display the emptying time of the dust collecting container 220 to the user. .

To this end, the cleaner body 100 or the dust collecting unit 200 or the handle (not shown)

When the display unit (not shown) is provided, and the foreign matter is collected in a predetermined amount or more inside the dust collecting container 220, and the rotation range of the first pressing plate 310 is less than a predetermined angle, the dust collecting container 220 of the Indicate when the user is empty.

6 and 7 are plan views illustrating a process in which foreign matter is compressed in the dust collecting unit.

Hereinafter, a process of compressing a foreign material collected in the dust collecting container 220 will be described with reference to FIGS. 6 and 7.

When the cleaning is performed, the foreign matter separated from the cyclone unit 211 is stored in the foreign matter storage unit 221. In this process of storing the foreign material, the pair of pressure plates 310 and 320 compress the foreign material stored in the foreign material storage unit 221.

In detail, when the driving motor 430 is rotated in one direction, the rotational power of the driving motor 430 is transmitted to the driven gear 410 through the driving gear 420, so that the driven gear 410 is Is rotated. In addition, the rotation shaft 312 and the first pressing plate 310 are rotated by the rotation of the driven gear 410.

In this case, since the driving gear 420 and the driven gear 410 are engaged with each other, when the driving motor 430 rotates in one direction, the driving gear 420 rotates in the same direction as the driving motor 430. The driven gear 410 is rotated in another direction opposite to the rotation direction of the drive motor 430.

That is, it can be seen that the rotational direction of the driven gear 410 and the rotary shaft 312 is opposite to the rotational direction of the drive motor 430.

As described above, when the first pressing plate 310 is rotated in another direction (counterclockwise in FIG. 6), the first pressing plate 310 is a foreign material between the first pressing plate 310 and the second pressing plate 320. This is pushed toward one side of the second pressing plate 320 to compress the foreign material. The rotation of the first pressing plate 310 is continued until the resistance generated in the process of pressing the foreign material reaches a set value.

When the resistance reaches a predetermined value or more, the power applied to the driving motor 430 is cut off and the first pressing plate 310 is stopped in a state in which the foreign material is compressed. When the predetermined time passes, the driving motor 430 is driven again to rotate the first pressure plate 310.

Here, since the first pressing plate 310 is stopped in the state in which the resistance force reaches the set value, the rotation direction is converted and rotated clockwise as shown in FIG. 7.

When the first pressure plate is rotated in the clockwise direction, the first pressure plate 310 moves the foreign material between the first pressure plate 310 and the second pressure plate 320 toward the other side of the second pressure plate 320. Push it to compress the foreign material.

This compression action is repeated until the rotation range of the first pressing plate 310 is less than a predetermined angle.

In addition, the partition plate 230 is formed in the horizontal direction below the foreign material separation unit 210. The partition plate 230 serves to partition the foreign matter separating unit 210 and the dust collecting container 220.

In addition, the partition plate 230 is that the foreign matter stored in the dust collecting container 220 is scattered to the foreign matter separating unit 210 in a state in which the foreign matter separating unit 210 is coupled to the dust collecting container 220. It plays a role to prevent more.

In addition, the partition plate 230 is provided with a foreign material discharge port 231 for discharging the foreign matter separated from the cyclone portion 211 to the dust collecting container 220.

At this time, the foreign material outlet 231 is preferably formed on the opposite side of the second pressure plate (320). The reason for this is to maximize the amount of foreign matter compressed on both sides of the second pressing plate 320, to maximize the dust collection capacity of the foreign material and at the same time minimize the scattering of foreign matter in the process of storing the foreign matter inside the dust collection container 220. To do this.

As described above, in order to couple the foreign matter separating part 210 and the dust collecting container 220, the foreign material separating part 210 is provided with upper and lower handles 212 and lower handle 223.

First, when power is supplied to the vacuum cleaner, suction force is generated by the suction force generating means, and air containing foreign matter is sucked into the suction nozzle by the air suction force.

In addition, the air sucked through the suction nozzle flows into the suction port 211a of the main cyclone part through the main body suction part 110. In addition, the air introduced through the inlet port 211a of the main cyclone part is guided in a tangential direction to the inner wall of the main cyclone part 211 to form a spiral flow, whereby the foreign matter contained in the air It is separated and lowered by the difference in centrifugal force.

As described above, the dust falling while spirally flowing along the inner wall of the main cyclone part 211 is stored in the main storage part 221 through the foreign material outlet 231 of the partition plate 230.
