The present invention relates to a multi-cyclone dust collector having two or more cyclone dust collectors, and more particularly to a multi-cyclone dust collector to perform the process of separating and collecting the foreign matter forcedly sucked from the outside by using the cyclone principle It is about.

In general, the cyclone dust collector is a device that discharges the air to the outside of the foreign matter that rotates with the air using a centrifugal force and collects only the foreign matter from the air.

There are many types of cyclone dust collectors as described above, but among them, a multi-cyclone dust collector which forms a cyclone dust collector by connecting a primary cyclone dust collector and a secondary cyclone dust collector to perform dust collection again. It is possible to exhibit better dust collection performance than a single cyclone dust collector composed of only one.

That is, when the cyclone dust collector is introduced in a state where a large foreign material and a fine foreign material are mixed, the dust collection efficiency of the fine foreign matter is extremely reduced by the interference of the relatively large foreign matter. Therefore, the multi-cyclone dust collector has been developed to improve the dust collection performance by first collecting the relatively large foreign matter by the primary cyclone dust collector and then again collecting fine foreign matter in the secondary cyclone dust collector.

FIG. 1 schematically shows a conventional multi-cyclone dust collector as described above, and the structure of the conventional multi-cyclone dust collector will be described below in detail.

First, the multi-cyclone dust collector has a primary cyclone dust collector 10 and a secondary cyclone dust collector 20, a fan 30 for transmitting suction to each of the cyclone dust collectors 10 and 20, and a driving force to rotate the fan. It is largely composed of a fan motor 40 for transmitting.

The primary cyclone dust collector 10 is connected to the first cylindrical cyclone body 11 of the cylindrical shape, the upper circumferential surface of the first cyclone body 11, the first air inlet pipe 12 and air into which indoor air is introduced It is configured to include a first dust collector (13) is collected various foreign matter separated from.

Here, the first dust collecting tube 13 is formed on the bottom space of the first cyclone body 11, and is formed to be partitioned by the partition 14 from the space where the foreign matter is separated.

At this time, the partition 14 has a communication hole 15 is formed so that the separated foreign matter flows into the first dust collecting tube (13).

In addition, the secondary cyclone dust collecting unit 20 includes a second cyclone body 21 provided inside the first cyclone body 11 and a second air inflow through which air is introduced into the second cyclone body 21. The second dust collecting tube in which the foreign matter separated from the air is collected in the pipe 22, the air discharge pipe 23 through which the air flowing in the second cyclone body 21 is discharged, and the second cyclone body 21. It comprises a 24. The lower surface of the second cyclone body 21 is formed with a communication hole 25 communicated with the second dust collecting cylinder (24).
