Dust separating apparatus for vacuum cleaner
A dust separating apparatus for a vacuum cleaner which is compact in configuration and is capable of preventing dirt from piling up on an entrance channel is provided. The dust separating apparatus includes a dust collecting receptacle adapted to collect dirt, and a cyclone unit eccentrically disposed in the dust collecting receptacle and adapted to whirl air drawn in through an inflow channel thereof, and the inflow channel may have an inclined upper surface which slopes downward toward a bottom of the dust collecting receptacle by a predetermined angle.
1. A dust separating apparatus for a vacuum cleaner, the dust separating apparatus comprising of:
a dust collecting receptacle adapted to collect dirt; and
a cyclone unit eccentrically disposed in the dust collecting receptacle and adapted to whirl air drawn in through an inflow channel thereof, the cyclone unit including
a cyclone body having an inlet in fluid communication with the inflow channel and an outlet in fluid communication with a discharge channel through which air separated from dirt is discharged,
a first guide formed at a side of the inlet in a spiral pattern for whirling drawn-in air,
a second guide formed on an upper portion of the cyclone body facing the outlet and for whirling the drawn-in air, and
a grille disposed at the outlet for filtering the air;
wherein the inflow channel has an inclined upper surface which slopes downward toward a bottom of the dust collecting receptacle by a predetermined angle.
2. The dust separating apparatus as claimed in claim 1 , wherein the dust collecting receptacle is configured to be removably mounted on a cleaner body with an area protruding from the cleaner body,
wherein the cyclone unit is partially disposed in the protruding area of the dust collecting receptacle.
3. The dust separating apparatus as claimed in claim 2 , wherein a part of the cyclone unit forms a part of an exterior of the dust collecting receptacle.
4. The dust separating apparatus as claimed in claim 3 , wherein the dust-collecting receptacle has an upper cover formed on an upper portion thereof to selectively open the dust collecting receptacle,
wherein a handle is formed on the upper cover.
5. The dust separating apparatus as claimed in claim 4 , wherein the dust collecting receptacle has a lower cover formed on a bottom thereof and being openable to discharge collected dirt.
6. The dust separating apparatus as claimed in claim 1 , wherein the inflow channel is formed along an inner surface of the dust collecting receptacle.
7. A dust separating apparatus for a vacuum cleaner, comprising of:
a dust collecting receptacle adapted to collect dirt;
a cyclone unit disposed in the dust collecting receptacle, the cyclone unit including an inlet for drawn-in air, an outlet, a cyclone that separates dirt from the drawn-in air, a first guide formed at a side of the inlet in a spiral pattern for whirling the drawn-in air, a second guide formed on an upper portion of the cyclone body facing the outlet and for whirling the drawn-in air, and a grille disposed at the outlet for filtering the air; and
an inflow channel which has an inclined surface formed thereon and sloping downwards toward a bottom of the dust collecting receptacle by a predetermined angle, the inflow channel guiding the drawn-in air into the inlet,
wherein a part of the cyclone unit forms a part of an exterior of the dust collecting receptacle.
8. The dust separating apparatus as claimed in claim 7 , wherein the inflow channel is formed along an inner surface of the dust collecting receptacle.
9. The dust separating apparatus as claimed in claim 7 , wherein the cyclone unit is eccentrically disposed in the dust collecting receptacle.
10. The dust separating apparatus as claimed in claim 9 , wherein the dust collecting receptacle is configured to be removably mounted on a cleaner body with an area protruding from the cleaner body,
wherein the cyclone unit is partially disposed in the protruding area of the dust collecting receptacle.
11. The dust separating apparatus as claimed in claim 10 , wherein the dust-collecting receptacle has an upper cover formed on an upper portion thereof to selectively open the dust collecting receptacle,
wherein a handle is formed on the upper cover.
12. The dust separating apparatus as claimed in claim 11 , wherein the dust collecting receptacle has a lower cover formed on a bottom thereof and being openable to discharge collected dirt.
