In an embodiment of the present application, in order to solve the technical problem in the prior art that condensed water tends to accumulate in the water receiving tray, which leads to the growth of bacteria in the water receiving tray and reduces the quality of air supply.

As shown in Fig. 1, Fig. 12 and Fig. 13, a first diversion protrusion 51 and a second diversion protrusion 52 arranged oppositely are arranged in the water receiving tray 5, and the first diversion protrusion 51 forms a first slope surface 511, the first slope 511 extends downwards along one edge of the water receiving tray 5, and the second guide protrusion 52 forms a second slope 521, and the second slope 521 runs along the other edge of the water receiving tray 5 Extending downwards obliquely, a flow guide groove 53 is formed between the first flow guide protrusion 51 and the second flow guide protrusion 52; A drainage groove 54 is formed at the same end of the drainage groove 54, and a drainage pipe 55 is arranged at the bottom of the drainage groove 54, and the diversion groove 53 communicates with the drainage groove 54.

Specifically, for the water receiving tray 5, a first flow guide protrusion 51 and a second flow guide protrusion 52 arranged oppositely are formed inside it, and the two flow guide protrusions form slope surfaces respectively, so that when used During the process, the condensed water formed by condensation of the heat exchanger 2 flows into the diversion groove 53 via the slope guide, and the condensed water flows into the drainage groove 54 through the guide groove 53 .

The drainage groove 54 is arranged at one end of the water receiving tray 5 , and the area of the drainage groove 54 is smaller than the entire area of the water receiving tray 5 , so that the condensed water flowing in from the diversion groove 53 can be quickly discharged from the drain pipe 55 . Simultaneously, after shutting down, the condensed water accumulated in the drain tank 54 is less, which can effectively reduce the excessive accumulation of condensed water to cause bacterial growth and affect the cooling of the air outlet.

Since the drain groove is arranged at one end of the water receiving tray and the overall area is small, the drain groove The condensed water in the air can be discharged through the drain pipe as soon as possible, thereby reducing the residual amount of condensed water, improving the quality of air supply and improving user experience.

In one embodiment, the supporting surface 50 is formed at the part of the second slope surface 521 close to the diversion groove 53 , so as to support the lower end of the heat exchanger 2 through the supporting surface 50 . The whole heat exchanger 2 is arranged above the first flow guide protrusion 51 .
