[0002] like Figures 6-7 As shown, the electrical box structure 5 of the outdoor unit of the air conditioner is generally assembled on the intermediate partition 1 and fastened using hooks and screws. A hook structure is formed by an upper hook 4 at the top and a lower hook 6 at the bottom. The intermediate partition 1 has openings to allow for the placement of the electrical box in conjunction with the hook structure. During operation, outdoor rainwater, driven by the fan, poses a risk of being splashed onto the intermediate partition 1. The large gap between the old hook structure and the intermediate partition allows rainwater to enter the piping components and electrical control area through this gap.

[0003] In accordance with the electrical safety and rain protection requirements of the whole machine, a water-blocking sponge 7 needs to be pasted on the hook to prevent rainwater from entering. However, the temperature around the pipes is high when welding the pipes during the assembly process. To avoid the water-blocking sponge 7 being burned, it needs to be pasted after the pipes are welded. However, the space for pasting the water-blocking sponge 7 is small, making it difficult to paste, which also reduces the efficiency of synchronous assembly. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology in which sponge is pasted after the pipe is welded, the pasting space is small and the pasting is difficult, which affects the assembly efficiency, the purpose of this invention is to provide a waterproof hook structure, an electrical box structure and an air conditioner outdoor unit.

The upper end of the bending section is connected to the vertical section. The lower end of the bending section is connected to the limiting section. The limiting section is inserted into the relief groove and fixed in cooperation with the fixing protrusion.

[0009] As a further improvement of the present application: the bending section is formed by the lower end of the vertical section being inclined and bent towards the upper end of the limiting section to form a water retaining groove.

Embodiment

[0035] As shown in Figures 1-5 The application discloses a waterproof hook structure, which comprises:

[0036] A clearance groove 101 is formed on the intermediate partition plate 1, and a fixing protrusion 102 is formed on the side away from the electrical box mounting plate 2, and the fixing protrusion 102 is used for positioning the water blocking mounting plate 3.

[0037] In the embodiment, the clearance groove 101 and the fixing protrusion 102 are formed by stamping and pressing, the clearance is pressed on the position of the intermediate partition plate 1 relative to the water blocking mounting plate 3 to avoid assembly interference, and a mounting hole is also formed below the intermediate partition plate 1, and after the water blocking mounting plate 3 is positioned in cooperation with the clearance groove 101, the electrical box structure 5 is fixed by using screws.

[0038] A water blocking mounting plate 3 is arranged on the side of the electrical box mounting plate 2 in contact with the intermediate partition plate 1, and the water blocking mounting plate 3 is provided with a first fixing portion 31 which is clamped into the clearance groove 101 to block the fixing protrusion 102, and the first fixing portion 31 is bent at the position relative to the clearance groove 101 to form a water blocking groove 301, and the slope of the water blocking groove 301 is arranged to be inclined towards the direction of the fixing protrusion 102.

[0041] In addition, the position of the first fixing part 31 relative to the accommodation groove 101 is designed to be bent to form a slope, which effectively prevents rainwater from entering from the water inlet side of the intermediate partition plate 1. Since the water blocking groove 301 formed by the bending is inclined towards the direction of the fixed convex 102, the rainwater hitting the water blocking mounting plate 3 will slide down along the water blocking groove 301 towards the fixed convex 102, and then slide down along the water inlet side of the intermediate partition plate 1.

[0042] More preferably, the front side of the fixed convex 102 close to the water blocking mounting plate 3 is a hollow structure.
