1 to 5, an air conditioner according to an embodiment includes a clean module 100 and a humidification module 200 mounted on the clean module 100. [ The clean module 100 is mounted on the floor, and the humidification module 200 is mounted on the clean module 100.

The clean module 100 sucks outside air, filters the air, and provides filtered air to the humidification module 200. The clean module 100 removes foreign substances contained in the introduced outside air and discharges the purified air from which odor is removed to the humidifying module 200. The humidification module 200 receives the filtered air and humidifies the humidifying air to provide moisture, and discharges humidified air to the outside.

The humidification module 200 and the clean module 100 are separable from each other. The user can separate the humidification module 200 and the cleaning module 100 from each other and clean them. The user may remove the humidification module 200 from the cleaning module 100 and then supply water to the water tub 30 disposed therein. The user may supply water in a state where the humidification module 200 is stacked on the clean module 100.

The clean module 100 includes a suction passage 101 through which external air is sucked, and a filtering passage 102 through which the sucked air is filtered.

When the humidification module 200 stacks the clean module 100, a connection flow path 103 is formed to receive filtered air. A connection flow path formed on the side of the clean module 100 is defined as a clean connection flow path 104 and a connection flow path formed on the side of the humidification module 200 is defined as a humidification connection flow path 105.
