Description

Dust separating apparatus of vacuum cleaner

This embodiment relates to a dust separation apparatus of a vacuum cleaner.

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

Such a vacuum cleaner may be classified into a canister method in which a suction nozzle is provided separately from the main body and connected by a connecting pipe, and an upright method in which the suction nozzle is coupled to the main body.

On the other hand, a conventional vacuum cleaner includes a cleaner main body and a dust separating apparatus mounted on the cleaner main body to store dust separated from air. This dust separation device allows dust to be separated mainly by the cyclone principle.

The pair of suction portions 232 are formed in the tangential direction of the first cyclone body 230. The pair of suction portions 232 are spaced apart from each other by a predetermined interval. Accordingly, a pair of cyclone flows are generated in the cyclone chamber 231.

The first cyclone body 232 is provided with a dust discharge part 234 through which dust separated from the cyclone chamber is discharged. The dust discharge part 234 extends a predetermined length from the outside of the first cyclone body 230. The dust discharge part 234 is located between the pair of suction parts 232.

The first unit 210 simultaneously opens and closes the upper sides of the dust storage unit 102 and the distribution unit 104. In addition, the pair of suction parts 232 communicate with the distribution part 104, and the dust discharge part 234 communicates with the dust storage part 102.

Therefore, the air containing the dust is introduced into the distribution unit 104 through the inlet (refer to 105 of FIG. 5), and then flows into the dust separation unit 20 through the pair of suction units 232. . In addition, the dust separated in the dust separator 20 is dropped into the dust storage unit 102 through the dust discharge unit 234.

4 is a partial cutaway perspective view of a second unit constituting the dust separation unit of the present embodiment, FIG. 5 is a cross-sectional view taken along the line A-A of FIG. 1, and FIG. 6 is a cross-sectional view taken along the line B-B of FIG. 1.

4 to 6, in the state where the dust separator 20 is coupled to the dust collecting device 10, the pair of suction portions 232 are separated from the first cyclone body 230. It extends toward the back 104, the dust discharge portion 234 extends toward the dust separation unit 102 in the first cyclone body (230).

In addition, discharge holes 272 through which the air passing through the filter member 290 is discharged are formed at both side surfaces of the second cyclone body 270, respectively. In addition, discharge ducts 280 through which air passing through the discharge hole 272 flows are formed at both sides of the second cyclone body 270, respectively.

In addition, the air of each of the discharge ducts 280 is moved to a cleaner body (not shown) in the state of being laminated in the lamination passage 282.

On the other hand, the dust storage unit 102 is provided with a pressing member 110 for pressing the dust stored in the dust storage unit 102.

The pressure member 110 includes a pressure plate 112 and a rotation shaft 114 integrally formed with the pressure plate 112. A portion of the rotating shaft 114 is coupled to the fixed shaft 116 protruding upward from the inner lower surface of the dust storage unit 102.

In addition, the rotary shaft 114 is coupled to the driven gear 120 for power transmission. The driven gear 120 is coupled to the dust collecting device 20 on the outside of the dust collecting device 20, the shaft 122 of the driven gear 120 passes through the fixed shaft 116 to the rotating shaft ( 114) on the underside. And, although not shown, the cleaner body is provided with a drive gear selectively engaged with the driven gear, and a compression motor for rotating the drive gear. In addition, a part of the driving gear is exposed to the outside of the cleaner body. Accordingly, when the dust separator is mounted on the cleaner body, the driven gear is engaged with the driving gear.

Hereinafter, the operation of the dust separator will be described.

The air introduced into the distribution part 104 through the inlet 105 is distributed to each of the suction parts 232. In addition, some of the bulky dust is stored in the branch portion 232 in the process of distributing air to the respective suction portions 232.

In addition, the air distributed to each suction unit 232 is sucked in the tangential direction into the cyclone bodies 230 and 270.

Accordingly, as the air is sucked through each of the suction parts 132, a pair of cyclone flows corresponding to each other are formed in the cyclone bodies 230 and 270.

As a result of the pair of cyclone flows in a single space, the flow path area of the air is increased, thereby reducing the flow path loss of the air, thereby increasing the separation performance.

As a pair of cyclone flows are generated in a single space, the size of the cyclone portion may be smaller than that of a structure in which one cyclone flow is generated as in the related art.

The pair of cyclone flows are generated at both sides of the cyclone bodies 230 and 270, respectively, and move to the center portion, where the respective cyclone flows meet. Accordingly, a stronger cyclone flow is generated in the central portion of the cyclone bodies 230 and 270 than the cyclone flow generated at each of the suction portions 1320.

Therefore, when a pair of cyclone flows are collected at the center of the cyclone bodies 230 and 270, the flow strength becomes larger than when a single cyclone flow occurs in the same space, thereby further improving dust separation performance. It becomes possible.

In addition, the dust moved to the central portion of the cyclone body (230, 270) can be discharged to the outside through the dust discharge portion 234 by the strong cyclone flow, thereby improving the dust discharge performance Will be.

In particular, foreign matter such as hair can easily adhere to the inlet side or the inside of the dust discharge unit 234 by static electricity, but as the strong cyclone flow occurs on the dust discharge unit 234 side as described above Foreign matter such as hair does not adhere to the inner surface of the dust discharge portion 234, and can be smoothly discharged to the outside.

As described above, the air sucked into the cyclone bodies 230 and 270 is moved along the inner circumferential surfaces of the cyclone bodies 230 and 270, and is moved to the center of the cyclone bodies 230 and 270 to be collected. In the process, air and dust are separated from each other under different centrifugal forces due to their weight differences.

The separated dust (dotted line) is discharged from the central portion of the cyclone bodies 230 and 270 to the dust discharge unit 234, and the discharged dust is moved along the dust discharge unit 234 to store the dust. It is introduced into the portion 102.

On the other hand, the dust separated air (solid line) is discharged to the air discharge portion 280 through the discharge hole 272 after passing through the filter member 290. In addition, the air discharged to the air discharge part 280 is moved to the cleaner body in a state in which the air is discharged from the lamination passage 282.

Meanwhile, in order to empty the dust stored in the dust storage unit 102, the dust separation unit 20 is separated from the dust collecting device 10. Then, the dust collecting device 10 is turned upside down so that the dust stored in the dust storage unit 102 is discharged to the outside.

The second unit is rotated with respect to the first unit to clean the inside of the cyclone bodies 230 and 270 or the filter member 290. Then, the cyclone chamber 231 and the filter member 290 are cleaned.
