a first fan;
a discharge guide that discharges air passing through the first fan, the discharge guide including a discharge grill having a concave shape in a downward direction; and
an air flow controller configured to adjust a direction of air discharged from the discharge guide and being movable, the air flow controller including an introduction grill into which the air discharged from the discharge guide is introduced and having a convex shape in the downward direction, wherein:
when the air flow controller is in a first position of a laid-out state, the introduction grill is seated on an upper surface of the discharge grill, and
when the air flow controller moves from the first position to a second position of an inclined erected state, the introduction grill is spaced apart from the upper surface of the discharge grill.
2. The air cleaner according to claim 1 , wherein the air flow controller slidably moves from the first position to the second position.
3. The air cleaner according to claim 2 , wherein the air flow controller includes:
a fixed guide provided at a lower side of the introduction grill, the fixed guide having a first guide surface which is rounded; and
a rotation guide having a second guide surface which moves along the first guide surface.
4. The air cleaner according to claim 3 , wherein the fixed guide further includes a first guide bearing provided at a side of the first guide surface, the first guide bearing being configured to contact the rotation guide.
5. The air cleaner according to claim 3 , further including:
a gear that communicates with the rotation guide; and
a gear recess provided at the fixed guide into which the gear is inserted.
6. The air cleaner according to claim 5 , wherein the gear is positioned at the first guide surface, and at least a portion of the gear projects upward from the gear recess.
7. The air cleaner according to claim 5 , wherein the rotation guide further includes a rack that communicates with the gear.
8. The air cleaner according to claim 3 , wherein the rotation guide further includes a second guide bearing provided at a side of the first guide surface, the second guide bearing being configured to move along the first guide surface.
9. The air cleaner according to claim 1 , wherein the air flow controller further includes a rotational shaft, and wherein the rotational shaft guides rotation of the air flow controller in a clockwise or counter-clockwise direction when the air flow controller is in the first position or the second position.
10. The air cleaner according to claim 1 , wherein the air flow controller further includes a second fan, and wherein the first and the second fans are positioned on a same axis in a longitudinal direction.
11. An air cleaner, comprising:
a first fan;
a discharge guide that discharges air passing through the first fan, the discharge guide including a discharge grill having a concave shape in a downward direction; and
an air flow controller configured to adjust a direction of air discharged from the discharge guide and being movable, the air flow controller including an introduction grill into which the air discharged from the discharge guide is introduced and having a convex shape in the downward direction, wherein:
when the air flow controller is in a first position, the introduction grill is seated on an upper surface of the discharge grill, and
when the air flow controller moves from the first position to a second position, the introduction grill is spaced apart from the upper surface of the discharge grill, and wherein the air flow controller slidably moves from the first position to the second position.
12. The air cleaner according to claim 11 , wherein the air flow controller further includes a rotational shaft, and wherein the rotational shaft guides rotation of the air flow controller in a clockwise or counter-clockwise direction when the air flow controller is in the first position or the second position.
13. The air cleaner according to claim 11 , wherein the air flow controller further includes a second fan, and wherein the first and the second fans are positioned on a same axis in a longitudinal direction.
14. An air cleaner, comprising:
a first fan;
a discharge guide that discharges air passing through the first fan, the discharge guide including a discharge grill having a concave shape in a downward direction; and
an air flow controller configured to adjust a direction of air discharged from the discharge guide and being movable, the air flow controller including an introduction grill into which the air discharged from the discharge guide is introduced and having a convex shape in the downward direction, wherein:
when the air flow controller is in a first position, the introduction grill is seated on an upper surface of the discharge grill, and
when the air flow controller moves from the first position to a second position, the introduction grill is spaced apart from the upper surface of the discharge grill, and wherein the air flow controller includes:
a fixed guide provided at a lower side of the introduction grill, the fixed guide having a first guide surface which is rounded; and
a rotation guide having a second guide surface which moves along the first guide surface.
15. The air cleaner according to claim 14 , wherein the fixed guide further includes a first guide bearing provided at a side of the first guide surface, the first guide bearing being configured to contact the rotation guide.
16. The air cleaner according to claim 15 , wherein the rotation guide further includes a second guide bearing provided at a side of the first guide surface, the second guide bearing being configured to move along the first guide surface, and wherein the rotation guide further includes a rack that communicates with the gear.
17. The air cleaner according to claim 14 , further including:
a gear that communicates with the rotation guide; and
a gear recess provided at the fixed guide into which the gear is inserted.
18. The air cleaner according to claim 17 , wherein the gear is positioned at the first guide surface, and at least a portion of the gear projects upward from the gear recess.
19. The air cleaner according to claim 14 , wherein the air flow controller further includes a rotational shaft, and wherein the rotational shaft guides rotation of the air flow controller in a clockwise or counter-clockwise direction when the air flow controller is in the first position or the second position.
20. The air cleaner according to claim 14 , wherein the air flow controller further includes a second fan, and wherein the first and the second fans are positioned on a same axis in a longitudinal direction.
