Cyclone dust collecting apparatus for use in vacuum cleaner
First Claim
1. A cyclone dust collecting apparatus for use in a vacuum cleaner, mounted in a dust collecting chamber intercommunicating with a motor driving chamber of a cleaner body, for separating contaminants from an air that is drawn in through a suction brush by a centrifugal force, the cyclone dust collecting apparatus comprising:
- a contaminant receptacle having a contaminant chamber and an air discharge chamber, the contaminant chamber and the air discharge chamber respectively having open upper sides and partitioned from each other;
a cyclone unit connected to an upper portion of the contaminant receptacle in a manner of covering the contaminant chamber and the air discharge chamber, the cyclone unit having a hole corresponding to, respectively, an incoming air port through which foreign substance laden air flows in, a centrifuging chamber for separating the foreign substances from the air by a centrifugal effect, a contaminant discharge port through which the separated foreign substances are discharged, an outgoing air port through which cleaned air that is left after separation of the foreign substances is discharged out, and the air discharge chamber, the cyclone unit comprising;
a centrifuging receptacle having an open upper end, a closed lower end and a cylindrical side that has the contaminant discharge port formed therein;
a cover plate connected to an outside of the centrifuging receptacle, covering the contaminant chamber and the air discharge chamber, the cover plate having the hole formed therein;
a cap cover removably mounted on the centrifuging receptacle in a manner of covering the open end of the centrifuging receptacle, the cap cover having the incoming air port and the outgoing air port; and
a duct member connected to the upper portion of the cyclone unit, and having an air inflow channel that is connected to the incoming air port and an air outflow channel that interconnects the outgoing air port with the hole.
