Abstract

An air purifier having an improved air purification capacity. The air purifier includes a base, a body arranged at a top of the base and having a cylindrical shape at a portion thereof, a suction unit arranged within the body and having a suction port, a discharge unit arranged within the body and having a discharge port to discharge air intook by the suction unit, a blowing unit arranged within the body to blow air from the suction unit to the discharge unit, and a filter unit arranged within the body to purify air blown by the blowing unit, wherein at least one of the suction port and the discharge port has a periphery defining a surface having an oval or ovoid shape inclined from a central axis of the cylindrical body portion, wherein the suction unit is pivotally coupled to the body.

First claim

What is claimed is:

1. An air purifier comprising:
a base;
a body coupled to the base and having a cylindrical shape at a portion thereof;
a suction unit, arranged within the body, having a suction port to intake air;
a discharge unit, arranged within the body, having a discharge port to output the intake air;
a blowing unit, arranged within the body, to blow air from the suction unit to the discharge unit; and
a filter unit, arranged within the body, to purify the air moved by the blowing unit,
wherein at least one of the suction port and the discharge port has a periphery surface that is inclined from a central axis of the body,
wherein the filter unit is disposed on the suction unit and the suction unit is pivotally coupled to the body,
wherein the suction unit comprises:
a suction panel having a partial cylindrical shape and forming a cylindrical shape with the body;
a suction body formed with the suction port; and
a two-link mechanism coupled to the body,
wherein the filter unit is disposed on the suction body, and

wherein the suction panel includes a base coupling pin, and the base includes a pin receiving slot having an arc shape to receive the base coupling pin, such that the suction panel conducts rotational movement and translational movement with respect to the body and pivots without interference with the body.

2. The air purifier of claim 1 , wherein the surface of the at least one of the suction port and the discharge port is an ovoid shape in which a shorter axis does not pass through a center of a longer axis.

3. The air purifier of claim 1 , wherein the surface of the at least one of the suction port and the discharge port is an oval shape.

4. The air purifier of claim 2 , wherein at least a portion of the filter surface is an ovoid shape in which a shorter axis does not pass through a center of a longer axis.

5. The air purifier of claim 3 , wherein at least a portion of the filter surface is an oval shape.

6. The air purifier of claim 1 , wherein the suction unit pivots such that a rear side of the suction unit moves toward the base.

7. The air purifier of claim 1 , wherein the suction unit is pivotally coupled to the base and coupled to the body by a two-link mechanism, to open or close an interior of the body.

8. The air purifier of claim 1 , wherein the suction panel includes a filter identifier that is formed by opening a portion of the suction panel, to expose a portion of the filter unit.

9. The air purifier of claim 1 , wherein:
the suction body includes a suction grill arranged at the suction port; and
the filter unit is disposed on the suction grill.

10. The air purifier of claim 9 , wherein the suction body includes a filter support protruding in a direction perpendicular to a surface defined by the suction grill, to support a portion of the filter unit.

11. The air purifier of claim 10 , wherein the suction body includes a filter fixing portion protruding from the filter support in a direction parallel to the surface defined by the suction grill, to fix a portion of the filter unit.

12. The air purifier of claim 1 , wherein:
the two-link mechanism includes a link protrusion at a portion thereof coupled to the body, and
the body is formed with a link stopper to engage with the link protrusion during pivoting of the suction unit.

13. The air purifier of claim 12 , wherein the link protrusion is engaged with the link stopper such that the suction panel does not contact the base.
