5 is a perspective view of the dust compression unit 200 according to an embodiment of the present invention. Referring to Figure 5 will be described in detail the configuration and operation of the dust compression unit 200 of the present invention.

The dust compression unit 200 further includes a first case 320 for receiving the dust compression member 310, and the dust compression member 310 includes the piston 312, the compression plate 314, and the first motion. Member 316.

The first case 320 forms an appearance of the dust compressing unit 200 and communicates with the dust separating unit 200. That is, the first case 320 is formed with an inlet 322 through which the dust separated from the dust separation unit 200 flows.

In addition, the piston 312 reciprocates along the longitudinal direction of the first case 320 inside the first case 320. Therefore, the piston 312 preferably has an appearance corresponding to the internal shape of the first case 320.

In addition, the piston 312 is preferably formed in a hollow form to have a light weight to facilitate the reciprocating motion inside the first case 320.

In addition, the compression plate 314 is disposed on one side of the piston 312 to compress the dust separated from the dust separation unit 200.

That is, as the piston 312 reciprocates, the compression plate 314 disposed on one side of the piston 312 also reciprocates along the longitudinal direction of the first case 320, and the dust separation unit 200. The dust separated from is compressed by the compression plate 314.

On the other hand, the compression plate 314 preferably has an appearance that corresponds to the internal shape of the first case 320 in order to facilitate the reciprocating motion inside the first case 320 like the piston 312.

In addition, the compression plate 314 may be integrally formed with the piston 312, may be formed separately from the piston 312 may be coupled to one side of the piston 312.

On the other hand, the first movement member 316 is accommodated inside the piston 312, the first movement member 316 is coupled to one surface of the compression plate 314 in the longitudinal direction of the first case 320 The expansion and contraction causes the piston 312 to reciprocate.

That is, as described above, the dust compression member 310 is driven by a pressure gradient between the dust compression unit 200 and the vacuum motor 100 or by a pressure gradient between the dust compression unit 200 and the external atmosphere. The first movement member 316 expands and contracts by a vacuum or atmospheric pressure applied to the inside of the first movement member 316 communicating with the first flow path part 510. As it expands and contracts, the compression plate 314 compresses dust.

Specifically, when the vacuum cleaner of the present invention operates, the dust compression unit 200 is formed with a pressure lower than atmospheric pressure by the vacuum pressure generated by the vacuum motor 100 provided in the main body 10.

On the other hand, when the first passage 510 is connected to the first air passage 512 and the atmospheric pressure acts on the inside of the first movement member 316, the dust compression portion inside the first movement member 316.

Even when a vacuum pressure is applied to both the inside of the first movement member 316 and the inside of the dust compressing portion 200, the first movement member 316 is directly connected to the vacuum motor 100 through the first flow path portion 510. This is because the pressure loss occurs because the vacuum pressure of the vacuum motor 100 is applied to the inside of the dust compression unit 200 after passing through the dust separation unit 200.

That is, due to the pressure gradient generated according to the pressure difference of the vacuum pressure or the external atmosphere of the vacuum motor 100 applied to the inside of the first movement member 316 as described above, and the pressure inside the dust compression unit 200. The first movement member 316 is stretched, and the dust is compressed by the expansion and contraction of the first movement member 316.

In addition, since the dust compressing member 310 is operated by the vacuum pressure generated by the vacuum motor 100, the piston 312 is the first case of the 320 in order to compress the dust introduced from the dust separation unit 200 When reciprocating inside, there is an advantage of preventing noise.

On the other hand, the peripheral surface of the compression plate 314 is preferably formed to be spaced apart from the inner surface of the first case 320 by a predetermined distance. Referring to FIG. 5, the width and length of the rectangular compression plate 314 are smaller than the width and length of the inside of the first case 320.

If the circumferential surface of the compression plate 314 is formed to be in contact with the inner surface of the first case 320, the piston 312 is reciprocated due to the friction between the compression plate 314 and the inner surface of the first case 320 This is because the movement may not be facilitated and dust may be easily caught on one surface of the compression plate 314 to which the first movement member 316 is coupled.

On the contrary, if the circumferential surface of the compression plate 314 and the inner surface of the first case 320 are separated by a predetermined distance or more, the circumferential surface of the compression plate 314 and the inner surface of the first case 320 may be present. The problem arises that some dust is difficult to compress.

Therefore, the predetermined distance between the circumferential surface of the compression plate 314 and the inner surface of the first case 320 is preferably 3mm to 7mm.

On the other hand, the dust compressing unit 200 is disposed on the outer surface of the first case 320, the liquid supply is in communication with the interior of the first case 320 to supply the liquid material to the interior of the first case 320 And further comprises an apparatus 330.

That is, the dust separated from the dust separation unit 200 is introduced into the interior of the first case 320 through the inlet 322, the dust and other foreign substances introduced into the interior of the first case 320 is easily scattered. A liquid supply device 330 is provided to prevent a possible state.

The liquid substance is preferably composed of a liquid having a certain viscosity. This is to form a lump having a predetermined weight by attaching dust and other foreign matters to each other easily by the viscosity of the liquid substance.

That is, the bellows 316a communicates with the vacuum motor 100 or the external atmosphere by the first flow path part 510. When the vacuum pressure is applied to the bellows 316a, the bellows 316a contracts in the longitudinal direction. When atmospheric pressure acts on the bellows 316a, it extends in the longitudinal direction.

The piston 312 reciprocates in the first case 320 by contraction or extension of the bellows 316a, and the compression plate 314 disposed on one side of the piston 312 compresses dust. Done.

8 is a perspective view showing the dust compressing member 310, wherein the first movement member 316 is an air bag 316c. Like the bellows 316a and the telescopic cylinder 316b, the airbag 316c also contracts or expands under the action of vacuum or atmospheric pressure, whereby the piston 312 is formed inside the first case 320. Will reciprocate in.

9 is a side view showing a combined state of the dust separation unit 200, the dust compression unit 200 and the dust collecting unit 700 according to an embodiment of the present invention.

It is configured to include.

According to one embodiment, the opening and closing member 410 is provided to selectively communicate with the vacuum motor 100 or the external atmosphere, by the pressure gradient between the opening and closing device 400 and the vacuum motor 100 or the external atmosphere. Drive to perform the opening and closing operation.

On the other hand, the vacuum cleaner of the present invention is provided in the second flow path part 610 and the second flow path part 610 which communicates the opening and closing device 400 with the vacuum motor 100 or the external atmosphere to vacuum the opening and closing device 400. It further includes a second flow path switching unit 620 for selectively communicating with the motor 100 or the external atmosphere.

That is, the second flow path part 610 includes a second air flow path 612 and a second vacuum flow path 614. The second air flow path 612 communicates the opening and closing device 400 with the external atmosphere. The second vacuum flow path 614 communicates the opening and closing device 400 with the vacuum motor 100.

Therefore, when the second flow path switching unit 620 communicates the opening and closing device 400 with the external atmosphere, atmospheric pressure acts on the opening and closing device 400, and the second flow path switching unit 620 opens and closes the switching device 400. When the 400 is communicated with the vacuum motor 100, the vacuum pressure generated by the vacuum motor 100 acts on the switching device 400.

On the other hand, the opening and closing member 410 constituting the opening and closing device 400 includes a separation plate 414, the second movement member 416 and the second case 412, the separation plate 414 is a dust collecting part 700 By opening and closing the discharge port 712 formed in the cover 710 of the cover, it is selectively opened and closed between the dust compression unit 200 and the dust collector 700.

When the separator 414 closes the discharge port 712, the separator 414 compresses the dust together with the compression plate 314. When the separator 414 opens the discharge port 712, the compressed plate 314 pushes the compressed dust toward the discharge port 712, and the compressed dust flows into the dust storage unit.

In addition, one end of the second movement member 416 is connected to the separator plate 414 to open and close the discharge port 712 by moving the separator plate 414.

On the other hand, since the separator 414 opens and closes the discharge port 712 formed in the cover 710, it is formed in a rectangular shape so as to correspond to the shape of the discharge port 712. However, since the separator 414 serves to open or close the discharge holes 712, the separator 414 may be formed in a circular or polygonal shape if the width of the separator plate 414 is larger than that of the discharge holes 712. The content of the present invention is not limited by the shape of the plate 414.

In addition, the second movement member 416 is accommodated in the second case 412 and stretches in the longitudinal direction of the second case 412. That is, any member may be used as long as the second movement member 416 is connected to the separator 414 to extend and contract in the longitudinal direction of the second case 412.

On the other hand, as described above, the opening and closing member 410 is provided to selectively communicate with the vacuum motor 100 or the external atmosphere, by the pressure gradient between the opening and closing device 400 and the vacuum motor 100 or the external atmosphere. In order to perform the opening and closing operation, a vacuum pressure or atmospheric pressure is applied to the inside of the second movement member 416 communicated with the second flow path part 610 so that the second movement member 416 is stretched and the second movement is performed. As the member 416 expands and contracts, the separating plate 414 performs an opening and closing operation.

Specifically, the operation process of the second movement member 416 is similar to the operation process of the first movement member 316, when the vacuum cleaner of the present invention operates the vacuum motor 100 provided in the main body 10 Due to the vacuum pressure generated by the inside of the dust collector 700, a pressure lower than atmospheric pressure is formed.

On the other hand, when the second flow path 610 is connected to the second air passage 612 and the atmospheric pressure acts on the inside of the second movement member 416, the dust collecting part 700 inside the second movement member 416. A pressure higher than the inside of) is formed. Therefore, the second movement member 416 extends along the length direction of the second case 412.

In addition, when the second flow path part 610 is connected to the second vacuum flow path 614 and a vacuum pressure acts on the inside of the second motion member 416, the dust collecting part is formed inside the second motion member 416. A pressure lower than the interior of 700 is formed. Accordingly, the second movement member 416 contracts along the length direction of the second case 412.

Even when a vacuum pressure is applied to both the inside of the second moving member 416 and the inside of the dust collecting part 700, the second moving member 416 directly contacts the vacuum motor 100 through the second flow path part 610. Although communicating, the inside of the dust collecting part 700 is passed through the dust separation unit 200, the vacuum pressure of the vacuum motor 100 is applied to the pressure loss occurs.

That is, the second pressure is generated by the pressure gradient generated according to the pressure difference in the vacuum pressure or the external atmosphere of the vacuum motor 100 applied to the inside of the second movement member 416 and the dust collecting part 700. The movement member 416 expands and contracts, and the separation plate 414 selectively opens and closes the dust compressing unit 200 and the dust collecting unit 700 by the expansion and contraction of the second movement member 416.

In addition, since the opening and closing device 400 is operated by the vacuum pressure generated by the vacuum motor 100, when the opening and closing the discharge port 712 to discharge the compressed dust to the dust collecting unit 700, the noise is prevented from occurring There is this.

9 shows the opening and closing device 400, characterized in that the second movement member 416 is a bellows 416a, but similar to the first movement member 316, a telescopic cylinder 416b or an airbag. It may be any one of 416c.

10 to 12 are side views showing various forms of the second movement member 416 according to an embodiment of the present invention.

As described above, the second movement member 416 accommodated in the second case 412 is coupled to the separator plate 414 to stretch in the longitudinal direction of the second case 412. Any member may be used as long as the second movement member 416 extends and contracts in the longitudinal direction of the second case 412.

10 to 12, when the second moving member 416 is any one of the bellows 416a, the telescopic cylinder 416b, or the airbag 416c, the second moving member 416 may be a second one. The operation process of expanding and contracting along the length direction of the case 412 to allow the separating plate 414 to perform the opening and closing operation is performed by the first moving member 316 as described above so that the compressing plate 314 compresses the dust. Since the process is substantially the same, the detailed description is omitted.

That is, the second movement member 416 communicates with the vacuum motor 100 or the external atmosphere by the second flow path part 610, and when the vacuum pressure is applied to the second movement member 416, it contracts in the longitudinal direction. When the atmospheric pressure is applied to the second movement member 416, it is extended in the longitudinal direction.

Therefore, the separator 414 opens and closes the discharge port 712 by contraction or extension of the second movement member 416, thereby selectively opening and closing the dust compressing part 200 and the dust collecting part 700.

13 is a side view showing the shape of the third movement member 426 according to another embodiment of the present invention. That is, the opening and closing device 400 illustrated in FIG. 13 is operated by a mechanical structure other than the vacuum pressure generated by the vacuum motor 100, unlike the opening and closing member 410 illustrated in FIG. 9.

That is, the opening and closing member 420 performs the opening and closing operation by operating by a separately provided drive motor 422, the opening and closing member 420 is configured to include a separating plate 424, the third movement member 426. .

In addition, when the separator 424 opens and closes the discharge port 712 by using the driving motor 422, the third movement member 426 is formed of a rigid material unlike the second movement member 416. It is not necessary to provide a third case for accommodating the three movement members 426.

According to one embodiment, when the separator 424 opens the discharge port 712, the third movement member 426 moves toward the driving motor 422. When the third movement member 426 moves, the separator 424 coupled to the third movement member 426 also moves toward the driving motor 422, so that the discharge port 712 is opened.

In addition, when the separator 424 closes the discharge port 712, the third movement member 426 moves toward the discharge port 712 as opposed to opening the discharge port 712. Therefore, the separator 424 coupled to the third movement member 426 also moves toward the discharge hole 712, so that the discharge hole 712 is closed.

Meanwhile, the opening and closing device 400 described above is provided inside the dust collecting part 700, but may be provided outside the dust collecting part 700.

Accordingly, the vacuum pressure generated by the vacuum motor 100 acts on the first movement member 316, and a pressure lower than the pressure inside the dust compression unit 200 is formed inside the first movement member 316. . Therefore, the first movement member 316 is in a contracted state.

In addition, an external atmospheric pressure of the main body 10 acts on the second movement member 416, and a pressure higher than the pressure inside the dust collecting part 700 is formed inside the second movement member 416. Therefore, the second movement member 416 is in an extended state, and the separating plate 414 coupled with the second movement member 416 closes the discharge port 712.

That is, referring to FIG. 18, the first valve 522 is switched such that the first flow path part 510 communicates with the first air flow path 512, and the second valve 622 also has a second flow path part 610. Is switched to communicate with the second air passage 612.

Therefore, the external atmospheric pressure of the main body 10 acts on the first movement member 316 and the second movement member 416, and dust is compressed inside the first movement member 316 and the second movement member 416. Pressure higher than the pressure inside the part 200 and the dust collecting part 700 is formed.

Therefore, the first movement member 316 extends in the lengthwise direction of the first case 320 to compress the dust separated from the dust separation unit 200, and the second movement member 416 is separated because it is in an extended state. The plate 414 is in a state of closing the discharge port 712.

19 to 20 are side views illustrating a state in which the first movement member 316 is extended and the second movement member 416 is contracted according to an embodiment of the present invention, and FIG. 21 is a view of FIGS. 19 to 20.

That is, referring to FIG. 21, the first valve 522 is switched such that the first flow path part 510 communicates with the first air flow path 512, and the second valve 622 is connected to the second flow path part 610. Is switched to communicate with the second vacuum passage 614.

Therefore, the external atmospheric pressure of the main body 10 continues to act on the first movement member 316, and a pressure higher than the pressure inside the dust compression unit 200 is formed inside the first movement member 316. Therefore, the first movement member 316 extends to compress the dust.

In addition, a vacuum pressure generated by the vacuum motor 100 acts on the second movement member 416, and a pressure lower than the pressure inside the dust collecting part 700 is formed in the second movement member 416. Therefore, the second movement member 416 is contracted, and the separating plate 414 coupled with the second movement member 416 opens the discharge port 712. Therefore, the dust compressed by the first movement member 316 is discharged to the dust collecting part 700 through the discharge port 712.

22 is a side view illustrating a state in which the first movement member 316 is contracted and the second movement member 416 is extended according to an embodiment of the present invention, and FIG. 23 is a first flow path according to the state of FIG. 22.

Accordingly, the vacuum pressure generated by the vacuum motor 100 acts on the first movement member 316, and a pressure lower than the pressure inside the dust compression unit 200 is formed inside the first movement member 316. . Therefore, the first movement member 316 compresses the dust and then contracts again.

In addition, an external atmospheric pressure of the main body 10 acts on the second movement member 416, and a pressure higher than the pressure inside the dust collecting part 700 is formed inside the second movement member 416. Therefore, since the second movement member 416 extends again, the separator 414 coupled with the second movement member 416 closes the discharge port 712 after the compressed dust is discharged to the dust collecting part 700.

On the other hand, the piston 312 of the dust compression member 310 reciprocates along the longitudinal direction inside the first case 320, the separator 414 opens and closes the discharge port 712 formed in the cover 710 In this case, the opening and closing operation of the separator 414 preferably has a period larger than that of the reciprocating motion of the piston 312.

That is, the reciprocating motion of the piston 312 is for compressing the dust flowing into the first case 320, and the opening and closing operation of the separator 414 is compressed by the repeated reciprocating motion of the piston 312. This is because the dust is discharged into the dust collecting part 700.
