In the present embodiment, the cross-sectional shape of the support 80 is a boss shape.

Thus, setting the relation of the width d1 of the support 80 and the width d2 of the heat exchanger 40 to 0.25d4+.d3 < d4 can ensure smooth support of the heat exchanger 40 by the support 80 and sealing effect between the heat exchanger 40 and the support 80 while maximizing the capacity of the water receiving tank. The relationship between the height h1 of the support 80 and the lowest point height h2 of the top surface of the water receiving tank is: h1 is less than or equal to 2/3h2, so that the heat exchanger 40 can leave the bottom of the water receiving tank, the bottom of the heat exchanger 40 is prevented from being soaked in the water receiving tank, the heat exchange efficiency of the heat exchanger 40 is further reduced, condensed water on the heat exchanger 40 can flow into the water receiving tank, the condensed water generated on the surface of the heat exchanger 40 is ensured to be smoothly discharged outwards, and the condensed water discharging path length is reduced to improve the water discharging efficiency.
