As shown in fig. 3, the third air port group 304 includes a plurality of third air ports 306 and a plurality of water return ports 308, wherein the position of any water return port 308 is lower than that of any third air port 306, at least one water return port 308 is arranged at the bottom of the inclined plane, the area of the air outlet 102 is larger than that of the third air port group 304, the periphery of the air outlet 102 is provided with a first flange 112, and the first flange 112 is fixedly connected with the partition plate 302 and sealed. In addition, both ends of the cover plate 104 are detachably connected to the top plate 202 and the partition 302, respectively.
When the electric control box main body 200 works, electric elements in the electric control box continuously heat, the temperature of air in the electric control box is increased, the hot air naturally rises to the top plate 202 and is accumulated, the fan 300 generates negative pressure on one side of the partition plate 302, due to good sealing of all parts of an air duct in the whole air guide structure, the negative pressure is sequentially transmitted through the third air port group 304 on the partition plate 302, the air outlet 102 of the air guide assembly 10, the air inlet 100 and the first air port group 206 of the electric control box, attractive force is generated on the hot air accumulated on the top plate 202, the hot air flows out from the first air port group 206, is discharged to the fan 300 side of the partition plate 302 through the air inlet 100 of the air guide assembly 10, the air outlet 102 and the third air port group 304 of the partition plate 302, and is discharged outside the whole machine, and after the hot air flows out from the electric control box, negative pressure is also formed in the electric control box, air with lower external relative temperature enters the electric control box from the second air port group 208 of the bottom plate 204 under the attraction of the negative pressure, heat exchange is carried out on the electric control box, and the electric elements in the electric control box are continuously cooled, and the temperature in the electric control box is realized.
If water enters the air guide groove 106 through the third air port group 304 on the partition plate 302, the water is blocked by the waterproof plate 110 of the air outlet 102, flows from the top of the inclined plane to the bottom of the inclined plane, and flows back to the fan 300 side of the partition plate 302 through the water return port 308.
Specific embodiment II:
as shown in fig. 3 to 5, an air conditioner 40 according to another embodiment of the present invention includes the air guiding structure of the first embodiment.
The air conditioner 40 of the embodiment further comprises an air conditioner bottom plate 402 perpendicular to the partition plate 302 in the air guiding structure, a water receiving disc 404 is arranged on the air conditioner bottom plate 402, the position of the water receiving disc 404 is lower than that of the water return opening 308, water flowing back from the water return opening 308 can flow into the water receiving disc 404 and finally is discharged uniformly, in addition, the air outlet 102 in the air guiding structure is lower than that of the air inlet 100, the possibility that water flows from the air outlet 102 to the air inlet 100 and enters the electric control box can be reduced, and the reliability of the whole air conditioner is improved.
The technical scheme of the invention is described in detail by combining the drawings, and through the technical scheme of the invention, the heat dissipation cycle of the electric control box is realized only by improving the structure, the cost is reduced, the design is simplified, the reliability of the electric elements of the electric control box is improved, the service life of the electric elements of the electric control box is prolonged, and therefore, the cost of the whole air conditioner is reduced, and the reliability of the whole air conditioner is improved.
