Abstract
An air cleaning system can rapidly senses occurrence of local pollution, caused by fine dust, through a remote sensor hub and supplies purified air to a polluted area in a concentrated manner, thereby quickly purifying indoor air.
Claims25
An air cleaning system, comprising:
- a first purifier including a first case, a first suction portion disposed at the first case, and a first discharge portion for discharging a purified air upward;
- a second purifier disposed over the first purifier, the second purifier including a second case, a second suction portion disposed at the second case, and a second discharge portion for discharging a purified air upward;
- a first circulator disposed at the first discharge portion and configured to discharge the purified air from the first discharge portion and to rotate over a first angle of rotation in a left-right direction;
- and
- a second circulator disposed at the second discharge portion and configured to discharge the purified air from the second discharge portion and to rotate over a second angle of rotation in the left-right direction,
- wherein the first circulator and the second circulator are positioned at different heights in a vertical direction, and the first circulator and the second circulator are configured to rotate independently in the left-right direction.
