In addition, the upper edge portion of the guide rib 459 is smoothly curved, so that the insertion operation of the exhaust part 407 can be easily performed.

FIG. 6 is a cross-sectional view taken along line II ′ of FIG. 3 and with reference to FIG. 6, the internal structure of the dust collecting unit 400 and the operation of the dust collecting unit will be described in detail.

First, as described in detail with reference to FIG. 5, in the dust collecting unit 400 according to the present invention, a dust collecting body 406 and a sealing part 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 collecting 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 to introduce the outside air. 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. The conical filter 405 is applied in this way because the dust collecting unit side suction port 401 is located on the upper side, the cyclone flow of the high speed rotation occurs in the upper portion of the conical filter 405, and the relatively low speed in the lower portion. 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 coupling relationship between the conical filter 405, the blocking portion 404 and the flow preventing plate 403 will be described in detail.

7 is an exploded perspective view of the conical filter and the blocking portion separated.

The coupling relationship between the conical filter and the blocking unit will be described in detail with reference to FIG. 7. The conical filter 405 and the blocking portion 404 is formed as a separate component. And, below the blocking portion 404, a flow preventing plate 403 for reducing the rotational flow of air is formed integrally with the blocking portion 404.

As described above, since the blocking part 404 is formed of an article separate from the conical filter 405, when the conical filter 405 is to be cleaned, only the blocking part 404 is removed, and the user's hand has the conical shape. May touch the filter 405. Therefore, foreign matter, such as hair, which has adhered to the outer wall of the conical filter 405 can be cleaned conveniently.

In order to conveniently perform such coupling and disassembly, the conical filter 405 is provided in a conical shape with a narrow lower portion and a wider upper portion. A plurality of openings are formed in the body of the conical filter 405 so as to allow the clean air to pass therethrough, and an inserting portion 430 is provided to be inserted into the blocking portion 404 in a state where the lower portion thereof does not have openings. In addition, the insertion part 430 includes at least one first protrusion 431 protruding outward from an outer circumferential surface to be fixed after the blocking part 404 is inserted.

In addition, in order to allow the conical filter 405 to be separated from the dust collecting body 406, a seating surface 432 formed at an upper end of the conical filter 405 and corresponding to a lower side of the separation plate 437. And a guide rib 433 protruding from the spaced upper end of the seating surface 432.

In addition, an opening portion 474 is formed at an upper end of the blocking portion 404 to insert the insertion portion 430, and an insertion groove into which the first protrusion 431 is inserted is formed at an inner circumferential surface of the opening portion 474. 427). In addition, a plurality of flow preventing plates 404 extending radially in a plate shape are formed below the blocking part 404. The upper end of the flow preventing plate 404 forms an insertion part placing part 428 formed by cutting a portion of the flow preventing plate 404 so that the insertion part 430 is seated. The second protrusion 429 protruding downward is formed at both sides of the insertion groove 427.

The coupling operation of the conical filter 406 and the blocking unit 405 will be described with reference to FIG. 8.

First, the blocking part 404 is pushed upward at the position where the first protrusion 431 and the insertion groove 427 are aligned. If the first protrusion 431 and the insertion groove 427 are not aligned, the insertion part 430 may not be inserted into the blocking part 404. To this end, the size of the opening 474 and the inserting portion 430 is appropriately adjusted.

After the insertion part 430 is completely seated in the insertion part placing part 428, the upper end of the blocking part 404 and the filter body 473 of the conical filter 406 close each other, and the first protrusion ( The 431 are in contact with each other with a slight height difference to the second protrusion 429. In this state, as shown by the arrow in FIG. 8, the interruption | block part 404 is rotated in either direction from left to right. Then, the first protrusion 431 is passed over the second protrusion 429, the light locking operation can be performed. As such, the second protrusions 429 are formed at both sides of the insertion grooves 427 so that the locking operation may be performed even when the blocking unit 404 is rotated in any direction. In addition, in order to lightly ride over the inner circumferential surface of the blocking portion 405 which is inclined downward, the upper end of the first protrusion 431 may be inclined downward at a predetermined angle toward the outside.

9 is a view for explaining the coupling relationship of the dust collecting body of the conical filter.

9, a communication hole 434 through which the air passing through the conical filter 406 is discharged is provided at a predetermined position of the separation plate 437, and the guide rib is formed at an edge of the communication hole 434. A rib insertion groove 435 through which the 433 passes is formed. In addition, a third protrusion 436 protrudes above the separation plate 437 at a central portion between the rib insertion grooves 435.

Referring to the fixing operation of the conical filter 405 by the above configuration, first, the guide rib 433 and the rib insertion groove 435 are aligned by turning the conical filter 405 to an appropriate position. Then, the conical filter 405 is pushed upward to allow the guide rib 433 to pass through the rib insertion groove 435. In this state, the distance between the guide rib 433 and the seating surface 432 is slightly smaller than the thickness of the separating plate 437. At this time, when the conical filter 405 is turned, the plate of the separation plate 437 is pressed in the interval between the above, the upper end of the conical filter 405 is fixed to the separation plate 437. In addition, when the predetermined angle is rotated, the guide rib 433 comes in contact with the third protrusion 436, so that the rotation is prevented and fully fitted to the user, so that the force applied to the conical filter 405 can be stopped. .

As described, the conical filter 405 may be fixed as a separate component to the separation plate 437, the blocking portion 404 to the conical filter 405.

Therefore, when the user wants to clean the conical filter 405, the conical filter 405 removes only the blocking portion 404 while being fixed to the separating plate 437, and then removes the conical filter 405. You can clean it. When the conical filter 405 is to be cleaned with water, the conical filter 405 may also be removed from the separating plate 437 and cleaned.

On the contrary, when the conical filter 405 is fixed to the separating plate 437, the conical filter 405 may be fixed first with the blocking part 404 separated, and then the blocking part 404 may be fixed behind it. have. In this way, the user's field of view is blocked by the blocking unit 404, so that the alignment position of the guide rib 433 and the rib insertion groove 435 cannot be seen, so that the accurate position of the conical filter 405 can be easily found. Missing problems can be solved.

On the other hand, the structure of the projections 431, 429, 436 and the like in the above-described structure may be modified in any other form. For example, it may be used as any locking structure that is formed in place of the protrusion structure, the insertion groove is formed in the insertion portion 430, the protrusion may be formed in the blocking portion 404.

In addition, when the flow preventing plate 403 is greatly required, the flow preventing plate 403 may also be fixed to the blocking unit 404 later as a separate article.

Referring to FIG. 6 again, 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 in order to prevent leakage of the stored foreign material.

On the other hand, the large amount of foreign matter is filtered through the conical filter 405 and the air introduced 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. Then, after passing through the motor is exhausted to the rear of the vacuum cleaner body (100).

Meanwhile, a predetermined cover structure is further formed on the upper portion of the spacer 408. In detail, the first cover 410 constituting the overall cover structure, the third cover 412 and the second cover 409 protecting the front and rear of the first cover 410, and the first cover A cover insertion hole 411 is provided at 410 to fix the second cover 409.
