In detail, the pressing member 270 is coupled to the sidewall of the dust collecting container 210. The dust collecting container 210 is formed with a seating rib 281 in which a rotating shaft 274 providing a center of rotation of the pressing member 270 is seated. The seating rib 281 is protruded toward the center from the sidewall of the dust collecting container. The seating ribs 281 are formed in a semi-circular shape, and a seating groove 276 in which the seating ribs 281 are accommodated is formed in the rotation shaft 274.

In addition, the axis of the rotation shaft 274 of the pressing member 270 is inclined with the side wall of the dust collecting container 210, more specifically orthogonal.

That is, the rotation shaft 274 of the pressing member 270 is provided in the horizontal direction inside the dust collecting container 210. Thus, the pressing member 270 is vertically rotated. In addition, the rotation shaft 274 penetrates the sidewall of the dust collecting container 210 in a state of being seated on the mounting rib 281.

The motor shaft 412 of the driving motor 410, which will be described later, is coupled to the rotation shaft 274 that penetrates the sidewall of the dust collecting container 210.

In addition, the pressing member 270 includes a semicircular pressing plate 272. That is, since the dust collecting container 210 is formed in a substantially cylindrical shape, the pressing plate 272 is formed in a semi-circular shape, so that dust is smoothly compressed by the pressing plate 272.

At this time, the shape of the pressure plate 272 may vary according to the horizontal cross-sectional shape of the dust collecting container 210. For example, when the horizontal cross section of the dust collecting container 210 is formed in a square, the pressing plate 272 may also be formed in a square.

In addition, a partition 282 for dividing the inner space of the first dust storage unit 214 into two spaces is protruded from the bottom surface of the dust collecting container 210. In addition, the partition 282 is located below the rotation shaft 274. Accordingly, the bottom of the dust collecting container 210 may be divided into a first bottom 218 and a second bottom 219 by the partition 282.

Meanwhile, the driving device 400 includes a motor housing 420 coupled to the sidewall of the dust collecting container 210 and a driving motor 410 accommodated in the motor housing 420.

When the driving device 400 is coupled to the dust collecting container 210, the driving motor 410 is coupled to the rotation shaft 274. In addition, the motor housing 420 is provided with a terminal portion 424 for supplying power to the drive motor 410.

The dust collecting device mounting unit 170 is provided with an accommodating part 172 in which the driving device 400 is accommodated while the dust collecting device 200 is mounted on the dust collecting device mounting unit 170. The accommodating part 172 is provided with a power supply terminal 174 selectively contacting the terminal part 424. Therefore, when the dust collecting device 200 is mounted on the dust collecting device mounting unit 170, the terminal unit 424 is in contact with the power supply terminal 174 to move from the cleaner body 100 to the driving motor 410. Power supply is possible.

The motor housing 420 is coupled to the fastening rib 290 formed on the sidewall of the dust collecting container 210 in a state where the driving motor 410 is accommodated in the motor housing 420.

The fastening protrusion 422 is formed at an outer side of the motor housing 420, and a protrusion insertion hole 292 is formed at the fastening rib 290 to selectively insert the fastening protrusion 422.

Here, the drive motor 410 is preferably a motor capable of forward rotation and reverse rotation. In other words, the driving motor 410 may be a motor capable of bidirectional rotation.

Accordingly, the pressing member 270 may rotate forward and reverse, and as the pressing member 270 rotates forward and reverse, the first bottom 218 and the second bottom of the dust collecting container 210 may be rotated. The compressed dust is accumulated on the bottom 219.

As such, in order to enable forward and reverse rotation of the driving motor 410, a synchronous motor may be used as the driving motor 410.

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

At this time, the force applied to the motor is a resistance force (torque) generated when the pressing member 270 presses dust (the first bottom surface 218 or the second bottom surface 219 when dust is not present in the dust collecting container). torque, the rotational direction of the motor is changed when the resistance reaches a set value.

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 embodiment that the forward and reverse rotation of the pressing member 270 is enabled by a synchronous motor.

In addition, the drive motor 410 preferably continuously rotates the pressing member 270 forward and backward at the same angular speed so that dust can be easily compressed.

The dust compression process in the dust collector 200 configured as described above will be described.

Referring to FIG. 5, when power is applied to the driving motor 410 while the dust collecting device 200 is mounted on the cleaner body 100, the driving motor 410 is rotated in one direction. In addition, when the driving motor 410 is rotated, the pressing member 270 connected to the driving motor 410 is rotated in one direction (eg, clockwise direction). Then, the space between the one surface of the pressing member 270 and the first bottom surface 218 is narrowed, and the dust accumulated on the first bottom surface 218 is compressed.

When the resistance acting on the pressing member 270 becomes equal to or greater than a set value (for example, when the pressing member comes into contact with the first bottom surface 218), the driving motor 410 rotates in the opposite direction. Thus, the pressing member 270 is rotated in the counterclockwise direction. Then, the space between the other surface of the pressing member 270 and the second bottom surface 219 is narrowed, and the dust accumulated on the second bottom surface 219 is compressed.

When the resistive force acting as the pressing member 270 is equal to or greater than a set value (for example, when the pressing member comes into contact with the second bottom surface 219), the driving motor 410 is rotated in the opposite direction. Thus, the pressing member 270 is rotated in the clockwise direction.

Here, a part of the first bottom surface 218 in contact with the pressing member 270 may be referred to as a first contact portion 218a, and a part of the second bottom surface 218 in contact with the pressing member 270 may be removed. It may be referred to as a second contact portion 219a.

Then, the pressing member 270 may be rotated within an angle range θ1 between the first contact portion 218a and the second contact portion 219a based on the rotation center of the pressing member 270. In this case, a space corresponding to θ1 in the first dust storage unit may be referred to as a first space S1. On the other hand, at least a part of dust may be stored in a space corresponding to 360-θ1 (second space: S2).

Here, since the second space S2 of the first dust storage unit 214 is partitioned by the partition unit 282, the first bottom 218 in the process of compressing dust by the pressing member 270. It will be readily understood that the accumulation of dust (compressed) on the top of) and the dust (compressed) on top of the second bottom 219 can be prevented from being mixed.

According to this embodiment, since the dust stored in the dust collecting container can be compressed by the pressing member, there is an advantage that the dust collecting capacity of the dust collecting container is increased.

In addition, since the dust is kept compressed in the dust collecting container, it is possible to minimize the scattering of dust during the dust emptying process.

In addition, since the driving device is detachably coupled to the dust collecting container, the driving device of the dust collecting container can be separated from the dust collecting device, so that water can be prevented from entering the driving device.
