Dust collecting device for vacuum cleaner
First Claim
1. A dust collecting device of for mounting to a body of a vacuum cleaner to separate dust from an externally drawn air by using centrifugal force, the dust collecting device comprising:
- a first cyclone unit comprising a first cyclone chamber where the externally drawn air enters through a first inlet and spins, and a first dust collecting chamber where dust separated from the externally drawn air is collected; and
a second cyclone unit comprising a second cyclone chamber where air, discharged from the first cyclone unit, enters through a second inlet and spins, and one or more dust collecting parts formed on a circumference of a second cyclone body to separate minute dust from the air upon contacting with the air spinning within the second cyclone chamber.

Abstract
A dust collecting device of a vacuum cleaner includes a first cyclone unit comprising a first cyclone chamber where the air enters through a first inlet and spins, and a first dust collecting chamber where dust separated from the air is collected; and a second cyclone unit comprising a second cyclone chamber where the air, discharged from the first cyclone unit, enters through a second inlet and spins, and one or more dust collecting parts formed on a circumference of a second cyclone body to separate minute dust from the air upon contacting with the air spinning within the second cyclone chamber. Accordingly, efficiency in collecting minute dust by the dust collecting device increases.

13. A vacuum cleaner comprising:
-
a first cyclone unit comprising a first cyclone chamber where externally drawn air enters through a first inlet and spins, and a first dust collecting chamber where dust separated from the externally drawn air is collected;
a second cyclone unit comprising a second cyclone chamber where air, discharged from the first cyclone unit, enters through a second inlet and spins, and one or more dust collecting parts formed on a circumference of a second cyclone body to separate minute dust from the air upon contacting with the air spinning within the second cyclone chamber, wherein the first and second cyclone units form a dust collecting device;
a vacuum cleaner body;
a mount where the first cyclone unit is seated, a suction passage for guiding the externally drawn air to the mount, and a discharge passage for guiding the air discharged from the mount to the outside of the vacuum cleaner body, wherein the suction passage has an outlet formed within the mount that is connectible with the first inlet in parallel direction with respect to the mounting direction of the first cyclone body. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
