The condensed water generated by the indoor heat exchanger 120 drops into the water receiving area 410, and then flows into the inner water tank 422 through the outer water tank 421 and the filter part 500 in sequence.

The outer water tank 421 mainly plays a role in settling the dust particles and dirt with large mass in the condensed water.

Because the water storage area of the outer water tank 421 is large, the rising speed of the water level is slow in the process of storing the condensed water, so that the dust particles and dirt in the condensed water have enough time to automatically settle to the bottom of the outer water tank.
