1. A dust collecting apparatus for installation into a vacuum cleaner to centrifugally separate dust from drawn-in air, the apparatus comprising:
- a dust receptacle to collect the dust; and
a cyclone part inserted in the dust receptacle, wherein the cyclone part guides the drawn-in air vertically through a center of the cyclone part, allows the drawn-in air to flow in a tangential direction inside of the dust receptacle simultaneously from a plurality of directions into the dust receptacle, centrifugally separates the dust from the drawn-in air, and discharges the drawn-in air along the center.

7. A dust collecting apparatus for installation into a vacuum cleaner, comprising:
-
a dust receptacle; and
a cyclone part detachably inserted in the dust receptacle, the cyclone part comprising;
a suction passage connectable to a suction nozzle of the vacuum cleaner so as to guide the drawn-in air into the suction passage vertically through a lower portion of the dust receptacle, at least two inlets at an upper end of the suction passage, the at least two inlets being formed perpendicularly to the suction passage so that the drawn-in air is distributed between the at least two inlets and flows radially outward into the dust receptacle, a guide spirally extending from the cyclone part at each of the at least two inlets, the guide exerting a centrifugal force to the drawn-in air to centrifugally separate dust from the drawn in air, and a space part disposed under the guide at an outer circumference surface of the suction passage, the space part being in fluid communication with a pair of discharge passages at an upper portion of the dust receptacle. - View Dependent Claims (8, 9, 10, 11)
