In addition, since the configuration of the flow closure part 600 is installed in the partition part 300, the flow closure part 600 also has the advantage of being capable of smooth cleaning when the cyclone dust collector is cleaned.

Meanwhile, in the exemplary embodiment of the present invention, a first filter member 710 is further provided inside the second space 520 formed by the partition part 300 and the cover part 400, and the outlet pipe 410 is provided. The air inlet side of the) further suggests that the second filter member 720 in the form of a mesh is further provided.

The first filter member 710 and the second filter member 720 as described above are a series of components for removing the fine dust in the air flowing through the outlet pipe 410, wherein, the first filter member ( 710 is preferably formed of at least one of a sponge filter or a HEPA filter.

Hereinafter, the operation of the cyclone dust collector according to the embodiment of the present invention configured as described above will be described.

First, when the operation control of the vacuum cleaner is made, the air suction force is generated while the fan-motor assembly 20 is driven.

The generated air suction force is transmitted to a suction hose (not shown) through a cyclone dust collector, and thus air containing various foreign substances in the room is sucked through the suction hose.

As described above, the air and the foreign matter sucked through the suction hose are introduced into the first body 110 through the first air inlet 120 of the primary cyclone dust collector 100 and then through the first air outlet 130. Outflow to the outside of the first body (110).

Air and foreign matter introduced into the first body 110 during the above process are guided by the guide ribs 112 provided in the first body 110 of the first body 110. It is guided to the inner wall and turns in a spiral flow. Thus, the foreign matter in the air is separated from the air by the centrifugal force and collected in the bottom space (or inside the dust collecting chamber in communication with the bottom space) in the first body 110, and the air is blown into the other pipe ( 111 and the first air outlet 130 sequentially pass through the first space 510, which is an external space of the first body 110.

Subsequently, the air flowing into the first space 510 is introduced into the second body 210 through the second air inlet 220 of the secondary cyclone dust collector 200, and then the guide tube 330 and the first air. Passes sequentially through the two air outlet 230 and the communication hole 310 is discharged to the second space (520).

In the meantime, the foreign matter separated from the air is appropriate in the dust collecting space (the bottom space in the second body or the dust collecting chamber communicating with the bottom space) of the secondary cyclone dust collecting part 200 during the above-described series of processes. When the dust is excessively collected, the foreign matter may overflow to the outside of the secondary cyclone dust collector 200 in a state of being piggybacked on air flowing through the secondary cyclone dust collector 200. have.

However, considering that the flow closure part 600 is installed in the communication hole 310 communicating with the second air outlet 230 of the secondary cyclone dust collector 200, the foreign matter overflowed is the flow closure part. Blocked in 600, the outflow is prevented.

In particular, in the above process, since the foreign matter blocks each mesh of the flow closure part 600, the pressure in the space where the cyclone dust collector is installed is gradually increased.

Therefore, the dust collecting indicator 10 installed in the space provided with the fan-motor assembly 20 in the vacuum cleaner is operated, which allows the user to know when to discharge the foreign matter for the cyclone dust collector.

Of course, as described above, even if the clogging occurs due to the foreign matter overflowed in the flow closure part 600, the foreign matter is caused by the suction force generated by the driving of the fan-motor assembly 20. After passing through the 600 may flow through the outlet pipe 410 of the cover 400.

However, the foreign matter passing through the flow closing part 600 is a second filter installed in the air inlet side of the first filter member 710 and the outlet pipe 410 in the second space 520 formed by the cover 400. As the foreign matter is filtered by the filter member 720, the foreign matter is prevented from flowing into the space in which the fan-motor assembly 20 is mounted, thereby preventing damage to the fan-motor assembly 20 more stably.

On the other hand, it is possible to reuse by performing the cleaning of the flow closure 600 while the user discharges the foreign matter collected in the cyclone dust collector by the above-described series of processes. In particular, the flow closure part 600 is installed in the cyclone dust collector detachable from the vacuum cleaner can be easily cleaned.

As described above, the multi-cyclone dust collector of the vacuum cleaner according to the present invention has various effects as described below.

First, the dust collection indicator of the cyclone dust collector of the present invention has the effect that the operation can be made when the dust collected in the cyclone dust collector is more than the appropriate capacity can be improved reliability of the operation of the dust collection indicator.

Second, the cyclone dust collector of the present invention has an effect that damage to the fan-motor assembly due to the foreign matter can be prevented because foreign matter overflowed from the secondary cyclone dust collector is filtered by the flow closure.

Third, the flow closure portion of the present invention has an effect that the cleaning can be easily made by being installed in the cyclone dust collector detachable from the vacuum cleaner.

Fourth, the cyclone dust collector of the present invention is again provided by the first filter member in the second space and the second filter member provided on the air inlet side of the outlet pipe even if foreign matter overflowed from the secondary cyclone dust collector passes through the flow closure portion. As a result, the damage of the fan-motor assembly due to the foreign matter can be prevented.
