First, as described in detail with reference to FIG. 7, the dust collecting unit 400 according to the present invention includes a dust collecting body 406 and a sealing unit 402 for selectively sealing the lower side of the dust collecting body 406 ( 415, the conical filter 405 accommodated inside the dust collecting body 406 to increase dust collection efficiency, the blocking portion 404 for preventing re-splash of the collected foreign matter, and the flow rate of cyclone flow is reduced. A flow preventing plate 403 to allow foreign matters to fall, and an exhaust part 407 placed above the dust collecting body 406 to allow the air discharged from the dust collecting body 406 to flow smoothly. And an interval portion 408 for collecting the air passing through the exhaust portion 407 in one direction, and covers 409, 410, 411 and 412 placed on an upper side of the exhaust portion 407. Included.

The configuration of the dust collecting body 406 will be described.

The dust collecting body 406 is provided with a plurality of walls extending up and down, the outer wall 418 formed on the outermost, the intermediate wall 419 formed inside the outer wall 418, and the intermediate wall ( An inner wall 420 formed inside 419 is included. The intermediate wall 419 and the inner wall 420 are not formed at intervals through which the dust collecting unit side suction port 401 passes, thereby allowing air to flow smoothly.

The space between the outer wall 418 and the intermediate wall 419 is the first foreign matter storage chamber 416, and the space between the intermediate wall 419 and the inner wall 420 is the second foreign matter storage chamber 417. The inner space of the inner wall 420 becomes the first foreign matter separation chamber 423. However, according to the shape of the dust collecting unit 400 in detail, the purpose of using the space may vary.

The operation or operation by the above-described configuration will be described in detail based on the flow order of air. First, air is introduced into the dust collecting unit 400 through the dust collecting unit side suction port 401. Here, the dust collection unit side suction port 401 is in contact with the front supporter 170 on the outside, and communicates with the first foreign matter separation chamber 423 on the inside, the outside air is introduced. In addition, a first inflow guide 421 is inward from the inner wall 420 so as to guide the flow direction of air in the direction of the inner circumferential surface of the first foreign matter separation chamber 423 inside the dust collecting unit side suction port 401. Protrudes.

During the cyclone flow of air in the first foreign matter separation chamber 423, the foreign matter falls downward and clean air passes through the opening of the conical filter 405 and is discharged upward. In this way, the conical filter 405 is applied because the dust collection unit side suction port 401 is located at the upper side, and the cyclone flow of the high speed rotation occurs at the upper side of the conical filter 405, and the lower side is relatively slow. Because cyclone flow occurs. That is, in the high-speed cyclone flow, the foreign material is rotated more outwardly, but in the low-speed cyclone flow, the foreign material is spread more inward, so that the filter member is conical in order to filter the foreign material. desirable.

The conical filter 405 is seated at the center of the separation plate 437 forming the top wall of the first separation chamber 423, it may be provided in a structure that can be selectively separated from the separation plate (437). In addition, the conical filter 405 is formed with a plurality of openings, of course, the air flows from the outside into the inside.

Here, the blocking portion 404 is placed under the conical filter 405 in order to prevent the re-splash of the falling foreign matter, as shown, the blocking portion 404 is expanded in diameter downwards, the foreign matter Re-scattering is blocked so it doesn't float. In addition, a flow preventing plate 403 is formed below the blocking portion 404 at regular intervals, so that the cyclone air flow is not reached with respect to the foreign matter once collected, thereby eliminating the phenomenon of the foreign matter being lifted up. .

The foreign material filtered in the first separation chamber 423 is stored in the first storage chamber 416 formed in the downward direction. Here, the first chamber sealing part 415 is placed at the lower end of the first storage chamber 416 so as to prevent leakage of the stored foreign material.

On the other hand, the large amount of foreign matter is filtered out of the air flowing through the conical filter 405 to the upper side of the separation plate 437. Therefore, there is a further need for cyclone flow to allow secondary fines to be filtered out. Hereinafter, the cyclone flow performed further will be described in detail.

Air passing through the conical filter 405 is introduced into the second separation chamber 424 through the second inlet guide 422. In addition, since the second inflow guide 422 directs the inner circumferential surface of the second separation chamber 424 in a tangential direction, air introduced into the second separation chamber 424 is cyclone inside the chamber. Flows.

The foreign matter separated by the cyclone flow in the second foreign matter separation chamber 424 is dropped downward and stored in the second foreign matter storage chamber 417. In order to prevent the falling foreign matters from scattering again, the lower portion of the second foreign matter separating chamber 424 is gradually contracted. In addition, the lower portion of the second foreign matter storage chamber 417 is sealed by the second chamber sealing part 402 so that the foreign matter collected in the second foreign matter storage chamber 417 does not leak.

Here, the second chamber sealing part 402 is coupled to the first chamber sealing part 415 by a bar-shaped connection structure. As such, the first chamber sealing portion 415 and the second chamber sealing portion 402 are connected by a bar-shaped connection structure to increase the internal volume of the first foreign matter storage chamber 416. . In other words, the foreign material is stored in the space spaced from the lower end of the second chamber sealing part 402 to the upper end of the first chamber sealing part 415, so that a small space such as a bar shape is provided in order to accommodate more foreign material. It is preferable to be connected by the member which occupies.

After the foreign material is filtered inside the second foreign matter separation chamber 424, the foreign matter is introduced into the exhaust part 407 via the exhaust part side suction port 425, and the gap between the exhaust part 407 and the spacer part 408 is provided. Gather in the space corresponding to Here, the diameter of the exhaust side suction port 425 is smaller than the inner diameter of the second foreign matter separation chamber 424, the foreign matter of the second foreign matter separation chamber 424 is the exhaust portion ( The possibility of flowing together with 407 can be further reduced. In other words, the foreign matter gathered on the inner surface of the second foreign matter separation chamber 424 is not discharged through the exhaust side inlet 425.

As described, air filtered by foreign matter by two cyclone flows is introduced into the motor through the motor side inlet 172. After passing through the motor, the exhaust gas is exhausted to the rear surface of the main body 100.

Meanwhile, a predetermined cover structure is further formed on the upper portion of the spacer 408.
