Abstract
A vacuum cleaner, including a cleaner body; and a dust collector provided in the cleaner body, wherein the dust collector includes a first cyclone provided within an outer case to filter foreign matter and dust 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; a screw provided at a lower side of and surrounding the first cyclone, and having at least one vane spirally extended along a flow direction of the air introduced into the outer case to induce the inflow of foreign matter and dust filtered by the first cyclone into a first storage section.
Claims21
A vacuum cleaner, comprising:
- a cleaner body;
- and
- a dust collector provided in the cleaner body, wherein the dust collector comprises:
- a first cyclone provided by an inner case and an 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
- a screw provided at a lower side of the first cyclone, and having at least one vane spirally extended along a flow direction of the air introduced into the outer case to induce an inflow of the first foreign matter filtered by the first cyclone into a first storage chamber.
A vacuum cleaner, comprising:
- a cleaner body;
- and
- a dust collector provided in the cleaner body, wherein the dust collector includes:
- a first cyclone provided by an inner case and an 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;
- a screw provided at a lower side of the first cyclone to guide the first foreign matter filtered by the first cyclone in a downward direction;
- and
- a compactor configured to be rotatable in first and second directions in a first storage chamber formed below the screw, wherein the compactor includes a cuff having an edge facing a lower side of the outer case, and configured with a plurality of ribs extending in a radial direction at predetermined intervals between the cuff and the compactor.
A vacuum cleaner, comprising:
- a cleaner body;
- and
- a dust collector provided in the cleaner body, wherein the dust collector includes:
- a first cyclone provided by an inner case and an 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
- a screw provided at a lower side of the first cyclone to guide the first foreign matter filtered by the first cyclone in a downward direction, and configured to be rotatable in at least one direction with respect to the first cyclone.
