Abstract

In 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 includes: 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; 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.

Claims

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; 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.

2. The cyclone dust collecting apparatus of claim 1, wherein the cyclone unit comprises:

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; and

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.

3. The cyclone dust collecting apparatus of claim 2, wherein the cyclone unit further comprises a grill member having an open upper end intercommunicating with the incoming air port of the cap cover, and a plurality of fine holes formed in a side, the cyclone unit being mounted in an interior of the centrifuging receptacle.

4. The cyclone dust collecting apparatus of claim 3, wherein the grill member comprises:

a cylindrical body integrally formed on a bottom of the centrifuging receptacle, and having open upper and lower ends; and

a lower cover connected to cover the open lower end of the cylindrical body.

5. The cyclone dust collecting apparatus of claim 2, wherein the outgoing air port is formed in the center of the cap cover, and the incoming air port is formed at an end of an air guide groove that is formed in near to the outgoing air port in a spiral manner.

6. The cyclone dust collecting apparatus of claim 2, wherein the centrifuging receptacle has one or more locking groove formed in the upper end, and the locking groove receives a locking protrusions protruding from a rim of the cap cover to be locked in the locking groove.

7. The cyclone dust collecting apparatus of claim 6, wherein the cap cover has at least a pair of handle holes formed in an upper side of the cap cover, for rotating the cap cover for locking/unlocking of the cap cover.

8. The cyclone dust collecting apparatus of claim 2, wherein the cover plate and the centrifuging receptacle are integrally formed with each other.

9. The cyclone dust collecting apparatus of claim 1, wherein, in between the cyclone unit and the duct member, a sealing member is provided.
