And the temperature of the condensed water is low, so that the heat radiation effect on the outdoor side heat exchanger 70 is good.

Referring to fig. 2 and 3, in order to make the condensed water quickly gather toward the water hitting area 612, in an embodiment, the bottom of the water hitting groove 611 is inclined downward in a direction toward the water hitting area 612. So after the comdenstion water is discharged to beating basin 611 from the drain outlet, the comdenstion water can make the comdenstion water all flow to beating water district 612 along the tank bottom rapid flow direction of beating basin 611, can make the comdenstion water all flow to beating water district 612, has reduced the time of comdenstion water towards beating water district 612 gathering, can realize beating water wheel 62 and beat water fast.

And the condensed water, which has passed through the outdoor side heat exchanger 70 and has not been evaporated, can flow toward the sump 611. Compared with the mode that the condensed water directly flows to the outdoor heat exchanger 70, the water collecting part 40 can reduce the water flow speed of the condensed water, so as to reduce or even avoid the splashing condition when the condensed water is sprayed on the outdoor heat exchanger 70, and ensure that the condensed water flows downwards along the outdoor heat exchanger 70 better. The condensed water can be sufficiently contacted with the outdoor heat exchanger 70, thereby achieving better heat dissipation effect and being beneficial to improving the heat exchange efficiency of the outdoor heat exchanger 70. The water outlet 42 may be disposed through the bottom of the water collecting tank 41 or the side wall of the water collecting tank 41.
