Air cleaner
An air cleaner is provided. The air cleaner may include at least one air cleaning module including a fan, a filter and an inlet through which air is suctioned into the filter; an air flow controller configured to be movably disposed on the at least one air cleaning module and including an air flow control fan to control a flow of the air discharged from the at least one air cleaning module. The air flow controller may be movable from a first position at which the air is discharged in an upward direction to a second position at which the air is discharged in a diagonally upward direction.
1. An air cleaner, comprising:
a first air cleaning module including a first fan, a first filter, a first inlet through which air is suctioned into the first filter, and a first outlet through which air passing through the first fan is discharged;
a second air cleaning module including a second fan, a second filter, and a second inlet through which air is suctioned into the second filter, wherein the first and second air cleaning modules are stacked in a vertical direction;
an air flow controller disposed on the second air cleaning module and configured to be movable from a first position to a second position, the air flow controller including:
a housing in which a third fan is installed, the third fan being configured to control a flow of the air discharged from the second air cleaning module; and
a second outlet through which air passing through the third fan is discharged, wherein the first position is a position in which a top of the air flow controller extends substantially parallel to a top of the second air cleaning module in height, and wherein the second position is a position at which the top of the air flow controller is at an angle with respect to the top of the second air cleaning module.
2. The air cleaner of claim 1 , wherein the air flow controller performs a first rotation in lateral directions at the first position or the second position.
3. The air cleaner of claim 2 , wherein the first rotation includes a rotation in a clockwise direction or a counter clockwise direction with respect to an axial direction.
4. The air cleaner of claim 2 , wherein the air flow controller is movable from the first position to the second position, or from the second position to the first position, by a second rotation in the upward direction or a downward direction.
5. The air cleaner of claim 2 , wherein the air flow controller includes a first guide to guide the first rotation.
6. The air cleaner of claim 5 , wherein the first guide includes:
a first gear including a first gear shaft; and
a first gear motor coupled with the first gear shaft.
7. The air cleaner of claim 6 , further including an air guide coupled with a bottom of the air flow controller, the air guide including a first rack interlocked with the first gear.
8. The air cleaner of claim 7 , wherein the air flow controller includes a second guide to guide the second rotation.
9. The air cleaner of claim 8 , wherein the second guide includes a fixed guide having a second gear and a second gear motor coupled with the second gear.
10. The air cleaner of claim 9 , wherein the air flow controller further includes a rotational guide having a second rack that interlocks with the second gear.
11. The air cleaner of claim 1 , wherein the first and second air cleaning modules each generate an independent air flow.
