As shown in FIG. 2, the dust collecting apparatus 500 includes a dust collecting container 510 having a dust collecting space formed therein, and a scattering preventing plate 525 provided inside the dust collecting container 510 to prevent scattering of foreign substances. And a discharge member 530 mounted above the scattering prevention plate 525 to form a primary cyclone device together with the dust collecting container 510.

The shatterproof plate 525 is provided in the form of a half moon in which the disc is divided in half, the central axis is rotatably coupled to the inside of the dust collector (510).

As such, the reason why the scattering prevention plate 525 is installed is that when the dust collecting container 510 is inverted in order to discard the foreign matter or dust collecting on the lower portion of the scattering preventing plate 525, the discharge of the foreign matter and dust collecting is prevented. In order to be smooth, the shatterproof plate 525 is to be quickly switched to the standing state from the lying state.

A first cover member 540 is provided on an upper portion of the discharge member 530, and a plurality of secondary cyclone devices 550 are mounted on the primary cover member 540 to allow the discharge member 530. It serves to separate the discharged air and foreign matter again.

Here, the foreign matter discharged from the discharge member 530 may be light dust, small dust, and the like, which are not separated from the primary cyclone.

The first cover member 540 is provided with a first through hole 541 through which air and foreign matter discharged from the discharge member 530 pass. Therefore, the air and the foreign matter passing through the passage hole 541 is moved to the secondary cyclone device 550, and is separated through a cyclone action inside the secondary cyclone 550.

The second cover member 560 is provided on the first cover member 540. The secondary cover member 560 is coupled to the upper portion of the first cover member 540, at this time, the inner side formed by the combination of the first cover member 540 and the second cover member 560 The space is sealed to the outside.

Accordingly, air and foreign matter from the through hole 541 may move to the second cyclone 550 without leaking to the outside. That is, the inner space formed by the first cover member 540 and the second cover member 560 serves as a guide flow path.

The second cover member 560 is provided with a second through hole 561 through which air discharged from the second cyclone device 550 passes.

An outer cover 570 is provided on an upper portion of the second cover member 560, and the discharge cover 571 is provided at the outer cover 570 to be coupled with the guide (see FIG. 1, 409). The outer cover 570 is coupled to the second cover member 560, and the space formed between the outer cover 570 and the second cover member 570 is separated from the foreign material in the second cyclone device 550. The separated air forms a flow path through which the discharge part 571 can move.

Meanwhile, the upper cover 570 and the first and second cover members 540 and 560 are installed in the dust collecting container 510 by a coupling member 572 having a shape of “a” in an overlapping state. One end of the coupling member 572 is fixed to the upper portion of the upper cover 570 by a fastening bolt 573, and the other end of the coupling member 572 is formed on the outer circumferential wall of the dust collecting container 510. The locking jaw 514 is caught and fixed.

As shown in FIG. 3, the dust collecting container 510 is divided into a plurality of spaces. First, a first dust collecting part 511 constituting a primary cyclone apparatus together with the discharge member 530, and the first dust collecting part A second dust collecting part 512 disposed adjacent to the first dust collecting part 511 and surrounded by the second dust collecting device 550, and partially surrounded by the second cyclone apparatus 550, and surrounding the second dust collecting part 512. The second cyclone device 550 is accommodated therein and includes a third dust collecting part 513 in which dust discharged from the second cyclone device 550 is collected.

One side of the dust collecting container 510, specifically, one side of the first dust collecting part 511 passes foreign substances and air sucked through the suction nozzle (see FIG. 1, 100) into the dust collecting container 510. An inlet 515 for introducing the inlet is provided.

On the other hand, the dust collector 510 is connected to the inlet 515, the air and foreign matter passing through the inlet 515 one side or the other side of the dust collector 510, specifically, the first dust collector 511 Alternatively, a guide tube 516 for selectively guiding to the second dust collecting part 512 is provided.

The guide tube 516 spans the inner space of the dust collecting container 510 and the outer space of the dust collecting container 510, and specifically, the second dust collecting part 512 is external to the inside of the first dust collecting part 511. Connected in the direction.

As shown in FIG. 4, the inlet 515 and the first dust collecting part 511 are selectively communicated to an upper side of the guide tube 516 disposed on the first dust collecting part 511 of the dust collecting container 510. Or, the switching device 700 for communicating the guide pipe 516 and the inlet 515 is provided.

The switching device 700 is provided to be rotatable in one direction or two directions.

The switching device 700 is provided on the inlet 515 to be rotatable, the inside of which is hollow, and is bent, the rotating tube 701 and the outside of the rotating tube 701. A shielding member 702 blocking the guide tube 701 and a supporting part 703 protruding from the outer circumferential surface of the rotary tube 701 and connected to the shielding member 702 to support the shielding member 702. .

Meanwhile, the rotation tube 701 is engaged with the shielding member 702 and the guide tube 516 according to the first direction rotation of the switching device 700 and the second direction rotation of the switching device 700. ) And the movement trajectory of the discharge hole 712 of the rotary tube 701 and the movement trace of the shielding member 702 so that the engagement between the guide tube 516 and the guide tube 516 is smoothly formed. Do.

In order to collect dust in a dry collecting method without the user putting a dust collector inside the dust collecting container 510, as shown in FIG. 5, the switching device 700 is rotated in a first direction, The shielding member 702 blocks the inlet of the guide tube 516 and allows the inlet 515 and the first dust collecting part 511 to communicate with each other.

In this state, when the vacuum motor provided in the main body (see FIG. 1, 400) operates, a vacuum pressure is generated inside the dust collecting container 510, and external dust and foreign matter are introduced into the inlet 515 by the vacuum pressure. ) And the inlet portion 711 and the discharge port 712 of the rotary tube 701 is discharged to the first dust collector 511.

Since the rotary tube 701 is provided in a bent form, when the rotary tube 701 is rotated as shown in FIG. 5 to discharge air to the first dust collecting unit 511, the discharge hole 712 opens the inner wall of the first dust collecting unit 511. Overlooked.

Thus, when foreign matter and air are discharged to the first dust collecting part 511 through the discharge port 712, the discharged air and foreign matter moves along the dotted line direction, and the inner circumferential wall of the first dust collecting part 511 is moved. Therefore, it performs rotational cyclone movement.

As described above, foreign matter and air are separated by the cyclone motion.

At this time, the shielding member 702 is prevented from entering the guide tube 516 by maintaining the state blocking the inlet portion 591 of the guide tube 516.

In addition, the shape of the shielding member 702 may correspond to the shape of the inlet of the guide tube 516 so that the shielding function of the shielding member 702 can be assured.

Since the rotation cyclone phenomenon should occur smoothly in order to implement such a dry collecting method, the switching device 700 should be disposed above the scattering prevention plate 525.

Because foreign matter and air rotate above the shatterproof plate 525, a phenomenon in which the foreign matter and air are separated by a difference in centrifugal force should occur, and the foreign matter separated from the air falls while the scattering plate 525 falls. This is because dust is collected at the bottom.

As shown in FIG. 6, when the dry collecting method is performed, the foreign matter D separated from the air in the primary dust collector 511 is accumulated in the lower space of the primary dust collector 511.

In particular, it accumulates in the lower portion of the shatterproof plate 525, which is a foreign matter (D) because of the space between the edge of the shatterproof plate 525 and the inner wall of the first dust collecting part 511. ) Because it is cumulative.

Air and light fine foreign matter separated from the foreign matter passes through the discharge member 530, and moves along the flow space S1 formed between the first cover member 540 and the second cover member 560. After that, it is introduced into the secondary cyclone device 512.

Air and fine foreign matter (d) introduced into the secondary cyclone device 512 is a rotational cyclone movement therein, the fine foreign matter (d) falls down according to the movement of the third dust collector 513 Accumulate inside.

Meanwhile, the air separated from the fine foreign matter d is discharged from the secondary cyclone apparatus 550 and along the space S2 formed between the second cover member 560 and the outer cover 570. After moving, it passes through the discharge part 571 formed in the outer cover 570 to be discharged to the outside of the dust collector 500 and moves in the direction of the vacuum motor (not shown).

Hereinafter, the wet collection method using the dust collection will be described.

In order for a user to put a dust collector in the dust collecting container 510 and collect dust by a wet collecting method, as shown in FIG. 7, first, the switching device 700 is held and the opposite direction is opposite to the first direction. When rotating in the second direction, the shielding member 702 is spaced apart from the inlet portion 591 of the guide tube 516, the discharge port 712 of the rotary tube 712 and the inlet of the guide tube 516. Part 591 is engaged.

In order to maintain such an engagement state, the edge shape of the discharge port 712 of the rotary tube 701 and the inlet portion 591 of the guide tube 516 preferably correspond to each other.

In this state, when the vacuum motor provided in the main body (see FIG. 1, 400) operates, a vacuum pressure is generated inside the dust collecting container 510, and external dust and foreign matter are introduced into the inlet 515 by the vacuum pressure. After passing through), receives the guide of the rotary tube 701 and moves in the direction of the guide tube 516.

As illustrated in FIG. 8, foreign matter and air that have passed through the guide tube 516 are introduced into the second dust collector 512 through the outlet portion 592 of the guide tube 516.

The lower space inside the dust collecting container 510 is filled with a dust collecting W, and the collecting dust W fills a lower space of the first dust collecting part 511 and the second dust collecting part 512.

Therefore, when the foreign matter and air are introduced into the second dust collecting part 512 by the vacuum suction pressure of the vacuum motor (not shown), it is mixed with the dust collecting W, and the dust collecting W is introduced. It is shaken by the force of air and foreign objects.

As shown in FIG. 9, when the dust collecting material W mixed with the foreign matter passing through the second discharge port 592 is shaken, water droplets may splash inside the first dust collecting part 511 and the second dust collecting part 512. However, in the first dust collecting part 511, the scattering of the dust collecting material W is limited by the scattering preventing plate 525.

In the case of the second dust collecting part 512, since there is no component such as the discharge member 525 provided in the first dust collecting part 511 thereon, limiting the dust collection (W) scattering motion splashing upwards therein It is not necessary to do this, and even if the scattering movement to the upper portion is severe, it is limited by the first cover member 540.

When the wet collecting method by the dust collecting W is made, foreign matter is collected in the dust collecting W.

On the other hand, the upper space of the first dust collecting part 511 and the second dust collecting 512 is partitioned by the partition wall 519, but the lower space is in communication.

 In addition, since the storage height h of the dust collector W is preferably lower than the height of the communicating lower space, the air separated from the foreign matter moves through the lower space to the first dust collecting part 511. .

After passing through the discharge member 530, the second cyclone is moved along the flow space S1 formed between the first cover member 540 and the second cover member 560. Flows into device 512.

Here, the height of the uppermost end of the outlet 592 should be higher than the storage height h of the dust collector W, so that all foreign matter moving in the direction of the outlet 592 is collected in the dust collector W. To do this.

If the upper end of the outlet portion 592 is formed higher than the storage height h of the dust collector W, the foreign matter is not mixed with the dust collector W if the air can flow freely to the portion. By moving to the free space without being able to perform the original function of collecting foreign matter by the dust collecting (W).

However, even when the water level of the dust collector W is formed higher than the outlet portion 592 to collect foreign matters, the dust collector is disposed in the air inside the first dust collector 511 and the second dust collector 512. There may be a fine foreign matter (d) not collected by (W).

Therefore, the air introduced into the secondary cyclone device 512 and the fine foreign matter d contained in the air have a rotational cyclone movement therein, and the fine foreign matter d falls down according to the movement. Accumulated inside the third dust collecting unit 513.

Meanwhile, the air separated from the fine foreign matter d is discharged from the secondary cyclone apparatus 550 and along the space S2 formed between the second cover member 560 and the outer cover 570. After moving, it passes through the discharge part 571 formed in the outer cover 570 to be discharged to the outside of the dust collector 500 and moves in the direction of the vacuum motor (not shown).

Therefore, in the present invention, a dry collection method or a wet collection method may be selectively used according to the characteristics of the foreign matter, and the collection method may be switched by simply operating the switching device 700.

And, it is possible to perform the dry collection method and the wet collection method with only one cleaner without having to provide a cleaner for the dry collection method and a cleaner for the wet collection method, respectively.
