Included.

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

The dust collection body 406 is provided with a plurality of walls extending up and down, the outer wall 418 is 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 multi-dust collection 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 multi-dust collection unit 400, 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 multi dust collection unit 400 through the multi dust collection unit side suction port 401. Here, the multi 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 formed at the inner wall 420 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 intake port 401 of the multi-dust collection unit. It protrudes inward.

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 to the upper portion of the conical filter 405 because the cyclone flow inlet 401 is located on the upper side, the cyclone flow of relatively high rotation occurs, the lower portion is relatively slow Is due to the cyclone flow of. 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 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. After passing through the motor, the exhaust gas is exhausted to the rear surface of the main body 100.

At this time, as air descends while turning along the inner surface of the small cyclone 752, an upward airflow is formed at the central portion of the small cyclone 752. This is similar to the air currents formed in the eye of a typhoon. Therefore, the upward airflow is guided by the plurality of guide tubes 754 and flows above the dust collecting container 710 to be collected in the assembly space 770.

In this process, the fine foreign matter turning with the air in the small cyclone 752 is ejected to the lower side of the small cyclone 752 without being caught in the rising air by inertial or centrifugal force. Therefore, these fine foreign matters are accumulated in the second dust collector 756.

Meanwhile, the air collected in the assembly space 770 flows into the upper cover 720 and is discharged through the discharge port 724 through the discharge passage 722.

On the other hand, since the connection pipe 780 is formed between the discharge port 724 and the motor assembly 640, the purified air exiting the multi-dust collection unit 700 is as shown in Figure 14 along the connection pipe 780. It flows into the head of the motor assembly 640.
