The vacuum cleaner is a device for cleaning the external environment by filtering foreign substances contained in the air sucked by the vacuum pressure inside the device. In the vacuum cleaner, in order to filter foreign matter from the sucked air, a dust collecting unit for filtering foreign matter is placed therein by a predetermined filtering device.

On the other hand, the filtering device includes a filter of a porous material in which foreign matter is filtered while the air is passed through the medium, and a cyclone-type filter in which foreign matter is removed from the air by cyclone flow of air. In addition, the filter of the porous material is removed when the foreign matter is deposited, or cleaned, or if a lot of foreign matter is deposited, there is a problem that can not be used continuously. On the other hand, since the cyclone filter allows foreign matter to be separated and removed by the air flow of the cyclone during the cyclone flow of air, the use of the cyclone filter is increasing in recent years.

Recently, a multi-cyclone dust collecting unit has been introduced to generate a plurality of cyclone flows in a single dust collecting unit. Since the foreign matter is removed by a plurality of cyclone flows, the foreign matter is removed. The removal efficiency is even higher. In addition, since foreign matters are removed by a plurality of cyclone air flows, the filter of the porous material does not need to be separately installed, so that the user does not need to clean the filter separately.

In addition, the parking unit is generally to be formed on the rear or bottom of the vacuum cleaner.

In particular, in order for the nozzle part to be entirely supported by the parking part, the parking part must maintain a certain strength or more. However, when the parking portion is formed on the bottom of the vacuum cleaner, there is a problem in that the strength is weak and the parking portion is broken or the original function cannot be properly performed.

The present invention is proposed to solve the above problems, and an object of the present invention is to propose a vacuum cleaner and a nozzle parking structure of a vacuum cleaner to provide a parking portion with a strong strength on the bottom of the vacuum cleaner.

In addition, as in the case where the multi-cyclone dust collecting unit is applied, when the base structure of the vacuum cleaner is formed in multiple layers, it is proposed a nozzle parking structure of the vacuum cleaner and the vacuum cleaner to keep the parking portion firmly in shape. For the purpose of

And a gap 408 for collecting the air passing through the exhaust 407 in one direction, and covers 409, 410, 411 and 412 that are placed above the exhaust 407. do.

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, the dust 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. 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 applied in a conical shape to filter the foreign material. desirable.

Here, the first chamber sealing part 415 is placed at the lower end of the first foreign matter storage chamber 416 to prevent leakage of the stored foreign material.

On the other hand, the air flowing through the conical filter 405 to the upper side of the separation plate 437 is largely filtered foreign matter. 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 plurality of second foreign matter 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 foreign matter separation chamber 424 in a tangential direction, air introduced into the second foreign matter separation chamber 424 may be formed in the chamber. Cyclone flow occurs.

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 dropped foreign material from scattering again, the lower portion of the second foreign matter separating chamber 424 is 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.

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 in the second foreign matter separation chamber 424, the foreign material is introduced into the exhaust part 407 via the exhaust part side suction port 425, and a gap between the exhaust part 407 and the spacer part 408 is provided. Gather in space. 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 circumferential surface of the second foreign matter separation chamber 424 is prevented from flowing out through the exhaust side suction port 425.

As described, the air filtered by foreign matter by two cyclone flows is introduced into the motor side inlet 172 and flows into the motor. 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.
