[0035] Embodiment 1

[0036] This embodiment discloses a waterproof structure for an outdoor unit of an air conditioner. Figure 1 As shown, the waterproof structure of the outdoor unit of the air conditioner includes an electric control box cover 100, an electrical appliance cover 200 and an electrical component 300, wherein the electrical component 300 is arranged in a cavity between the electric control box cover 100 and the electrical appliance cover 200, and also includes an electric control box cover rib 101 and an electrical appliance cover rib 201, wherein the electric control box cover rib 101 and the electrical appliance cover rib 201 are both located above the electrical component 300; the electric control box cover rib 101 is arranged on the wall surface of the electric control box cover 100 close to the cavity side and extends toward the electrical appliance cover 200 side; the electrical appliance cover rib 201 is arranged on the wall surface of the electrical appliance cover 200 close to the cavity side and extends toward the electric control box cover 100 side; the electric control box cover rib 101 partially overlaps with the electrical appliance cover rib 201.

[0037] The waterproof structure of the air conditioner outdoor unit of the present invention is provided with an electric control box cover rib 101 and an electric appliance cover plate rib 201 above the electric appliance component 300. Water flowing into the interior of the air conditioner outdoor unit from the top gap of the electric appliance cover plate 20 cannot drip onto the electric appliance component 300 due to the stopper of the electric control box cover rib 101 and the electric appliance cover plate rib 201, thereby ensuring that the electric appliance component 300 is not soaked by water. The electric control box cover rib 101 and the electric appliance cover plate rib 201 partially overlap, thereby further ensuring the protective effect of the electric control box cover rib 101 and the electric appliance cover plate rib 201 on the electric appliance component 300, thereby greatly improving the operating safety of the air conditioner outdoor unit.

[0038] In this embodiment, after the electric control box cover 100, the electrical appliance cover plate 200 and the electrical appliance component 300 are assembled, the electric control box cover ribs 101 and the electrical appliance cover plate ribs 201 are offset in the vertical direction to avoid interference between the electric control box cover ribs 101 and the electrical appliance cover plate ribs 201. In an optional embodiment, the electric control box cover ribs 101 are located above the electrical appliance cover plate ribs 201 in the vertical direction; in another optional embodiment, the electrical appliance cover plate ribs 201 are located above the electric control box cover ribs 101 in the vertical direction.

[0039] like Figure 2-3As shown, the electric control box cover rib 101 and the electrical appliance cover plate rib 201 partially overlap, and the length L of the overlapping portion, that is, the projection length L of the overlapping portion in the horizontal direction, has a numerical range of 3-10 mm.

[0040] In this embodiment, if the length of the overlapping portion is less than 3 mm, the overlap between the electric control box cover rib 101 and the electrical appliance cover plate rib 201 cannot be guaranteed, and the water stopped by the ribs is easy to flow out from the gap between the electric control box cover rib 101 and the electrical appliance cover plate rib 201; if the length of the overlapping portion is greater than 10 mm, in order to avoid interference between the electric control box cover rib 101 and the electrical appliance cover plate rib 201, it is necessary to increase the vertical distance between the electric control box cover rib 101 and the electrical appliance cover plate rib 201, which affects the waterproof effect. Therefore, selecting a reasonable overlapping portion length can not only effectively prevent water droplets from splashing onto the electrical components 300 and protect the electrical components 300, but also avoid interference between the electric control box cover 100 and the electrical appliance cover plate 200, and ensure that the electric control box cover 100 and the electrical appliance cover plate 200 can be assembled.

[0041] In this embodiment, Figure 2-3 As shown, the electric control box cover rib 101 is located above the electrical appliance cover rib 201 in the vertical direction.

[0042] This embodiment is preferred, such as Figure 4-5 As shown, the upper surface of the electric control box cover rib 101 is an inclined surface, and the upper surface of the electric control box cover rib 101 is inclined from the connection end of the electric control box cover rib 101 and the electric control box cover 100 to the direction close to the electrical component 300. The electric control box cover rib 101 is arranged above the electrical appliance cover rib 201, and the upper surface of the electric control box cover rib 101 is arranged as an inclined surface, so that the water stopped by the electric control box cover rib 101 can flow along the upper surface of the electric control box cover rib 101 to the upper surface of the electrical appliance cover rib 201, and avoid the electric control box cover rib 101 directly draining water and splashing water droplets onto the electrical component 300.

[0043] Further preferably, the value range of the angle α between the upper surface of the electric control box cover rib 101 and the horizontal plane is 5-25°.

[0044] If the angle α between the upper surface of the electric control box cover rib 101 and the horizontal plane is less than 5°, the inclination angle of the upper surface of the electric control box cover rib 101 is too small, and it is impossible to ensure that the water flows in the specified direction; if the angle α between the upper surface of the electric control box cover rib 101 and the horizontal plane is greater than 25°, the water flow velocity on the upper surface of the electric control box cover rib 101 is too high, causing splashing again. Therefore, the angle between the upper surface of the electric control box cover rib 101 and the horizontal plane is selected to be 5-25°, which can ensure that the water on the upper surface of the electric control box cover rib 101 flows out smoothly while avoiding secondary splashing caused by excessive water flow velocity.

[0045] This embodiment is preferred, such as Figure 4-5 As shown, the upper surface of the electrical appliance cover rib 201 is an inclined surface, and the upper surface of the electrical appliance cover rib 201 is inclined from the connection end of the electrical appliance cover rib 201 and the electrical appliance cover 200 to the direction away from the electrical appliance component 300. Setting the upper surface of the electrical appliance cover rib 201 as an inclined surface can make the water on the upper surface of the electrical appliance cover rib 201 flow along the electrical appliance cover rib 201 to the side away from the electrical appliance component 300, so as to prevent the electrical appliance cover rib 201 from splashing water droplets onto the electrical appliance component 300 when draining water.

[0046] Further preferably, the value range of the angle β between the upper surface of the electrical appliance cover rib 201 and the horizontal plane is 5-25°.

[0047] The angle between the upper surface of the electrical cover rib 201 and the horizontal plane is selected to be 5-25°. On the one hand, it can ensure that the water on the upper surface of the electrical cover rib 201 flows, and on the other hand, it can avoid secondary splashing caused by excessive water flow rate. In addition, it is also beneficial to reduce the difficulty of processing and assembling the electrical cover 200.

[0048] In another preferred embodiment, the upper surface of the electric control box cover rib 101 and the upper surface of the electrical appliance cover plate rib 201 are both inclined surfaces, the upper surface of the electric control box cover rib 101 is inclined from the connecting end between the electric control box cover rib 101 and the electric control box cover 100 toward the direction approaching the electrical component 300, and the upper surface of the electrical appliance cover plate rib 201 is inclined from the connecting end between the electrical appliance cover plate rib 201 and the electrical appliance cover plate 200 toward the direction away from the electrical component 300. In this embodiment, after water flows into the interior of the air conditioner outdoor unit through the gap at the top of the electrical cover 200, it drips along the digging hands on the electrical cover 200, and the electrical control box cover ribs 101 and the electrical cover ribs 201 form a stop for the dripping water. Since the upper surface of the electrical control box cover ribs 101 is an inclined surface, after water drops onto the electrical control box cover ribs 101, it flows along the upper surface of the electrical control box cover ribs 101 to the electrical cover ribs 201; at the same time, since the upper surface of the electrical cover ribs 201 is an inclined surface, the water flowing from the electrical control box cover ribs 101 to the electrical cover ribs 201 together with the water stopped by the electrical cover ribs 201 flows again to the side away from the electrical component 300, thereby effectively preventing the electrical component 300 from being immersed in water and ensuring the safe operation of the air conditioner outdoor unit.

[0049] This embodiment is preferred, such as Figure 4-5 As shown, the electric control box cover ribs 101 include an upper rib 1011 and a side rib 1012 of the electric control box cover. The side ribs 1012 of the electric control box cover are located on both sides of the electrical component 300. Figure 6-7As shown, the electrical appliance cover rib 201 includes an electrical appliance cover upper rib 2011 and an electrical appliance cover side rib 2012, and the electrical appliance cover side rib 2012 is located on both sides of the electrical appliance component 300. With the above arrangement, water blocked by the electric control box cover rib 101 and the electrical appliance cover rib 201 can flow out through both sides under the guidance of the side ribs, preventing direct drainage from causing splashing, and further ensuring the safety of the electrical appliance component 300.

[0050] In another preferred embodiment, the electric control box cover rib 101 is in an inverted U shape, and the electrical appliance cover plate rib 201 is in an inverted U shape. The electric control box cover rib 101 and the electrical appliance cover plate rib 201 are in an inverted U shape, which can provide multi-directional protection for the electrical components 300, and at the same time facilitate the smooth drainage of water on the rib surface to prevent water from gathering on the rib surface.
