The present invention relates to a vacuum cleaner, and more particularly to a cyclone dust collector that can be applied to a vacuum cleaner.

In general, the cyclone dust collector is a device that separates the dirt from the dust collecting air using centrifugal force, discharges the air to the outside and stores the dirt in a separate waste collection room, unlike the conventional dust bag (dust bag) It is widely used in that it can be used.

The cyclone dust collector has an inlet formed in contact with the outer circumferential surface of the cyclone seal to turn the air sucked from the inlet of the vacuum cleaner, and located at an upper portion of the cyclone seal, and an outlet through which the air from which dirt is separated by the cyclone seal is discharged. It is formed in the center of the upper end of the cyclone seal. That is, both the inlet and the outlet are formed on top of the cyclone seal. The cyclone dust collector having such a structure is lowered while separating the dirt by centrifugal force while the air introduced into the inlet flows inside the cyclone chamber. The air from which the dirt is separated rises again and is discharged to the outlet. As such, since both the inlet and the outlet are formed in the upper portion of the cyclone chamber, a phenomenon in which the descending air stream and the rising air stream collide inside the cyclone chamber occurs. In addition, such a phenomenon of collision of the airflow causes not only a loss of suction power but also a cyclone dust collection efficiency.
