Abstract
A vacuum cleaner including a cleaner body; and a dust collector provided in the cleaner body, wherein the dust collector includes an outer case forming a side appearance of the dust collector; a first cyclone provided within an outer case to filter dust and foreign matter from air introduced into the dust collector; a second cyclone accommodated within the first cyclone to separate fine dust from the air introduced into the first cyclone; and an upper cover mounted on a top of the outer case to cover the first and second cyclones and having an intake guide configured to introduce air into the outer case and an exhaust guide configured to discharge air from which fine dust is separated by the second cyclone.
Claims21
A vacuum cleaner, comprising:
- a cleaner body;
- and
- a dust collector provided in the cleaner body, wherein the dust collector includes:
- an outer case forming a side appearance of the dust collector;
- an inner case provided within the outer case;
- a first cyclone provided by the inner case and the outer case to filter first foreign matter from air introduced into the dust collector;
- a second cyclone having a plurality of hollow bodies in the inner case to separate second foreign matter from the air filtered from the first cyclone;
- and
- an upper cover mounted on a top of the outer case to cover the first and second cyclones and having an intake guide configured to introduce air into the first cyclone and an exhaust guide configured to discharge air from the second cyclone.
A vacuum cleaner, comprising:
- a cleaner body;
- and
- a dust collector provided in the cleaner body, wherein the dust collector includes:
- an outer case forming a side appearance of the dust collector;
- an inner case provided within the outer case;
- an upper cover coupled to a top of the outer case and having an intake guide and an exhaust guide;
- and
- at least one cyclone provided by the inner case and the outer case to filter air introduced into the outer case through the intake guide, wherein the air filtered by the at least one cyclone is discharged through the exhaust guide, and an inlet of the intake guide and an outlet of the exhaust guide are open in directions opposite to each other.
A vacuum cleaner, comprising:
- a cleaner body;
- and
- a dust collector provided in the cleaner body, wherein the dust collector includes:
- an outer case;
- a hollow inner case provided within the outer case;
- a first cyclone provided by the inner case and the outer case to filter first foreign matter from air introduced into the dust collector;
- a second cyclone having a plurality of hollow bodies in the inner case to separate second foreign matter from the air filtered by the first cyclone;
- a cover that covers a top of the second cyclone and including a communication hole corresponding to a vortex finder of the second cyclone from which air from which the second foreign matter is separated is discharged;
- and
- an upper cover that covers the cover wherein the upper cover includes:
- an intake port having a bent guide and extending toward an annular space between the outer case and the cover to introduce air into the annular space between the outer case and the cover so as to circulate in a spiral flow;
- and
- an exhaust port configured to communicate with the communication hole to discharge air discharged through the vortex finder.
