Of course, in other embodiments, the drain groove 520 may be disposed inside the groove 510, or in the middle of the groove 510. It should be noted that, as shown in fig. 4 and 7, the heat exchanger 400 includes an inner heat exchanger 400 and an outer heat exchanger 400, and although the groove 510 is provided with a step surface due to the drainage groove 520, due to the gravity of the heat exchanger 400, the fin 410 of the outer heat exchanger 400 is very likely to contact with the groove bottom of the drainage groove 520, which may cause the situation that the flow of the condensed water is not smooth. According to the technical scheme, the supporting convex rib 521 is arranged at the bottom of the drainage groove 520, so that the supporting convex rib 521 is perpendicular to the fins 410, the heat exchanger 400 is effectively supported, and the heat exchanger 400 is prevented from falling and contacting with the bottom of the water receiving groove. In this embodiment, the supporting ribs 521 are integrally elongated and extend along the extending direction of the water receiving trough. In addition, the cross section of the support rib 521 is trapezoidal to improve the stability of the support rib 521. Of course, in other embodiments, the supporting ribs 521 may have other shapes such as a bent shape, a wave shape, a grid shape, etc. The cross section of the support rib 521 may have other shapes such as a square, a rectangle, and a triangle.

The utility model discloses technical scheme is through setting up support protruding muscle 521 in water drainage tank 520 to support heat exchanger 400, thereby effectively prevent the tank bottom laminating of heat exchanger 400 and water drainage tank 520, and then make the water drain smoothly and difficult freezing jam on the water collector 500.

Further, as shown in fig. 5, the drainage groove 520 is annularly disposed, and the drainage groove 520 extends along a circumferential direction of the water collector 500. In this embodiment, the groove 510 is disposed annularly to facilitate receiving the lower end of the annular heat exchanger 400. The drainage grooves 520 are also annularly arranged, specifically, the drainage grooves 520 include four water flowing grooves, the four water flowing grooves extend along four sides of the water receiving tray 500, and the four water flowing grooves may be disconnected or communicated with each other. In this embodiment, four channels are substantially connected end to form an annular drain channel 520, but two adjacent channels are disconnected at the corners of the drip tray 500. It can be understood that the drainage groove 520 is annular, and when the condensed water on the annular heat exchanger 400 flows around, the condensed water can flow into the drainage groove 520, that is, the annular drainage groove 520 can improve the receiving rate of the condensed water.

Further, a plurality of supporting ribs 521 are arranged in the drainage groove 520, and the supporting ribs 521 are arranged at intervals along the circumferential direction of the water collector 500. Of course, in other embodiments, only one whole supporting rib 521 may be disposed in the water receiving slot and extend along the extending direction of the annular water receiving slot. However, compared with the prior art, the technical solution of the embodiment can effectively save the material of the supporting rib 521 and reduce the obstruction of the supporting rib 521 to the water flow in the drainage channel 520.

In this embodiment, as shown in fig. 5 and 6, a plurality of drainage branch grooves 530 are formed on the bottom surface of the groove 510 and are recessed downward, and the drainage branch grooves 530 are all located on the inner ring side of the drainage groove 520 and are all communicated with the drainage groove 520. It can be understood that when the condensed water flows down from the inside of the heat exchanger 400, the condensed water may flow into the drain branch groove 530 first, and then the water in the drain branch groove 530 flows into the drain groove 520; when the condensed water flows down from the outside of the heat exchanger 400, the condensed water directly flows into the drain groove 520. The technical scheme of the embodiment can effectively prevent water accumulation on the inner side of the evaporator, and condensed water on the heat exchanger 400 can be collected into the water drainage groove 520 and then is drained out of the water pan 500 in a centralized manner.

In other embodiments, the top end surface of the support rib 521 may be flush with the bottom surface of the groove 510, or the top end surface of the support rib 521 may be lower than the bottom surface of the groove 510, as long as the support rib 521 can support the heat exchanger 400 to prevent the heat exchanger 400 from contacting the bottom surface of the drain groove 520. And this embodiment technical scheme, through the tank bottom setting that will support protruding muscle 521 and be higher than recess 510, can minimize the contact of heat exchanger 400 and water collector 500 quotations, further promote the smooth and easy nature that the condensate water flows.

In addition, as shown in fig. 3 and 4, a sealing member 600 is provided between the heat exchanger 400 and the groove bottom surface of the groove 510. Since there is a gap between the heat exchanger 400 and the bottom surface of the groove 510, when the centrifugal fan 300 drives the air to blow out all around, the condensed water on the groove 510 is easily blown out through the gap, which causes a water blowing phenomenon. The effect of sheltering from through sealing member 600 of this embodiment technical scheme can effectively avoid taking place to blow the water phenomenon. Wherein, sealing member 600 can set up to the sponge spare, and the water absorption capacity of sponge spare is good, is favorable to promoting the water absorption capacity of sealing member 600, and simultaneously, the water on the sponge spare can also conveniently flow into in drainage tributary groove 530 and the water drainage tank 520.

In this embodiment, the distance between the bottom of the drainage channel 520 and the heat exchanger 400 is 3-5 mm, that is, the height of the support rib 521 protruding upward relative to the bottom of the drainage channel 520 is 3-5 mm. It can be understood that the distance between the bottom of the drain groove 520 and the heat exchanger 400 is not too large or too small, and if the distance between the bottom of the drain groove 520 and the bottom of the groove 510 is too large, the gap between the heat exchanger 400 and the bottom of the groove 510 is also large, which is more likely to cause the water blowing phenomenon, so that the thickness of the sealing member 600 needs to be increased; if the distance between the two is too small, the supporting ribs 521 cannot support the heat exchanger 400 well, so that the heat exchanger 400 is partially in contact with the bottom of the drainage groove 520, which is not favorable for the smoothness of the flow of the condensed water in the drainage groove 520.

Further, as shown in fig. 5, the water receiving tray is further provided with a water pumping groove 540, the water drainage groove 520 is communicated with the water pumping groove 540, and the bottom of the water drainage groove 520 is inclined downwards towards the water pumping groove 540. It can be understood that after the condensed water is collected into the drain groove 520, the condensed water in the drain groove 520 flows into the water pumping groove 540 again, and finally the condensed water is pumped out of the water receiving tray 500 by the water pump. In this embodiment, the tank bottom end of water drainage tank 520 is 0.5 ~ 2 towards the slope of water pump water pumping groove 540 downward sloping, so, is favorable to the comdenstion water in the water drainage tank 520 to flow towards water pump water pumping groove 540, guarantees rivers overall planning.
