The condensed water collected in the first collecting space 152 is guided along the drilling part 154 and collected in the second collecting space 312.

The cold condensed water collected in the second collecting space 312 flows to the upper end of the outdoor heat exchanger 320 through the falling hole 314. The condensed water dropped by the outdoor heat exchanger (320) is cooled by water cooling the hot refrigerant passing through the interior of the outdoor heat exchanger (320), and is collected into the upper surface of the base (130), that is, the guide passage (132).

The condensed water collected into the guide passage 132 is collected by the water collecting unit 136 and then forced upward by the condensate pump 372. The condensed water forced upward by the condensate pump 372 is a guide hose. Guided by 374 is introduced into the first collecting space 152.

While repeating this process, the outdoor heat exchanger 320 is water-cooled with cold condensed water generated from the outer surface of the indoor heat exchanger 210.

In addition, even if the condensate pump 372 sends a large amount of condensed water to the first catchment space 152 by using the air conditioner 100 for a long time, the catch tank ( Since the water is collected at 350, condensate is prevented from overflowing the water collecting unit 136.
