[0042] In this embodiment, the fixing portion 22 is disposed on the connecting plate 24 .

[0043] In this embodiment, the fixing portion 22 has a clamping space or a fixing hole, so that the cable 30 is clamped in the clamping space or passed through the fixing hole. Such a configuration facilitates the fixing of the cable 30 and is convenient for installation and disassembly.

[0044] Optionally, the fixing portion 22 is a hook.

[0045] The present invention also provides an air conditioner outdoor unit, please refer to Figures 1 to 7 , comprising a shell and an electrical box structure 1, wherein the electrical box structure 1 is arranged in the shell, wherein the electrical box structure 1 is the electrical box structure in the above embodiment.

[0046] In this embodiment, the air conditioner outdoor unit further includes a support plate 4, which is disposed in the housing, and at least a portion of the waterproof component 20 of the electrical box structure 1 and the support plate 4 together form a second water receiving groove 5 to receive water flowing down from the support plate 4. Such a configuration can receive water flowing down from the support plate 4, further improving the waterproof effect of the electrical box structure 1.

[0047] In this embodiment, at least a portion of the connection plate 24 of the waterproof component 20, a first water retaining edge 26 disposed on the connection plate 24, and at least a portion of the support plate 4 form a second water receiving groove 5, wherein the first water retaining edge 26 is the groove bottom of the second water receiving groove 5. In addition to forming the groove bottom of the second water receiving groove 5, the first water retaining edge 26 can also prevent water from splashing from the gap between the support plate 4 and the connection plate 24 to the opening 12 and then entering the accommodating cavity 11.

[0048] In this embodiment, the first water receiving groove 21 of the waterproof component 20 is connected to the second water receiving groove 5 through the first drainage port 23 of the waterproof component 20; the first water retaining edge 26 is provided with a second drainage port 261, and the second drainage port 261 is connected to the second water receiving groove 5, so that the water in the second water receiving groove 5 can be discharged through the second drainage port 261. Such a setting can make the water in the first water receiving groove and the second water receiving groove be discharged through the second drainage port to prevent water accumulation.

[0049] In this embodiment, the waterproof component 20 further includes a second water retaining edge 27, which is connected to the connecting plate 24 and is located above the second drain port 261. This arrangement prevents water from gradually entering the second water receiving groove from the second drain port and then splashing into the accommodating chamber 11 from the notch of the second water receiving groove.

[0050] In this embodiment, the connecting plate 24 is located above the electrical box body 10 of the electrical box structure 1, and the connecting plate 24 has a connecting end and a free end that are arranged opposite to each other in the vertical direction, the connecting end is connected to the electrical box body 10, the free end is located above the connecting end, and the first water retaining edge 26 is arranged between the connecting end and the free end; the supporting plate 4 has a first end 41, the first end 41 is located above the electrical box body 10 and is spaced from the electrical box body 10; the first water retaining edge 26 is arranged against the first end 41. Such an arrangement can prevent water from splashing from the gap between the supporting plate 4 and the connecting plate 24 to the opening 12 and then entering the accommodating cavity 11.

[0051] Specifically, a mounting hole is provided on the support plate 4 , the electrical box body 10 is inserted into the mounting hole, and the first end portion 41 is a part of the hole wall of the mounting hole.

[0052] In this embodiment, the housing includes a top cover 6, which is provided with an air outlet 61; the air conditioner outdoor unit also includes a fan blade 7, at least part of which is arranged opposite to the air outlet 61; the support plate 4 is arranged between the fan blade 7 and the opening 12 of the electrical box body 10 of the electrical box structure 1, and the opening 12 is arranged at the side of the electrical box body 10 and is arranged away from the fan blade 7; the waterproof component 20 is arranged at the top of the electrical box body 10 and is located between the opening 12 and the support plate 4; wherein there is a gap between the support plate 4 and the top cover 6; and / or, the support plate 4 is provided with a connecting hole 42, and the connecting hole 42 is located above the second water receiving groove 5. Since the side of the support plate 4 away from the fan blade 7 cooperates with the waterproof component to form the second water receiving groove 5, the second water receiving groove 5 can receive water flowing from the gap between the connecting hole 42 and the support plate 4 and the top cover 6, and prevent water from entering the accommodating cavity of the electrical box body 10.

[0053] In a specific implementation, water entering the housing from the air outlet 61 falls onto the fan blade 7, causing the fan blade 7 to splash water when it rotates, so that the water enters the front side (i.e., the opening 12) of the electrical box body 10; wherein, the water enters the accommodating chamber 11 through the opening 12 mainly Figure 6 , Figure 7Several paths are shown: ① Water passes over the guide ring and is hit on the top of the support plate 4, and flows down along the board wall across the gap between the top of the support plate 4 and the top cover 6; ② Water seeps through the screw holes (i.e., the connection holes 42) on the support plate 4 above the electrical box body 10, and flows to the front of the support plate, and flows down along the board wall; ③ Water splashes in through the gap between the electrical box structure 1 and the support plate 4 (i.e., the interval between the first end 41 and the electrical box body 10); ④ Water is attached to the cable 30 and flows directly to the mainboard electronic components along the cable 30. In order to solve the above four water inflow problems, in this application, the water entering through the ① and ② paths will not flow to the front of the electrical box body after flowing down the board wall, but will flow along the board wall to the second water receiving tank. The water in the ④ path flows to the local low point along the cable under the action of gravity, and drips into the first water receiving tank after gathering at the local low point. The first water retaining edge and the second water retaining edge can stop the water entering through the path ③, and prevent the water entering through the path ③ from gradually entering the accommodating cavity.

[0054] Specifically, in order to prevent water leakage, the first drainage groove and the second drainage groove are set to be smaller in size, with a depth less than the height of the connecting plate and a minimum width less than 10 mm. Figure 3 The width of the first drainage groove and the width of the second drainage groove in the front-to-back direction.

[0055] In this embodiment, the air conditioner outdoor unit also includes a cable 30 and a driving member 8, which is connected to the fan blade 7 to drive the fan blade 7 to rotate. One end of the cable 30 is connected to the driving member 8, and the other end of the cable 30 is connected to the main board 13 in the electrical box body 10; wherein the driving member 8 and the fan blade 7 are located above the electrical box structure 1.

[0056] Specifically, the width of the connecting plate 24 relative to the supporting plate accounts for at least 80% of the total width of the electrical box body. Figure 3 The width in the left-right direction.

[0057] In this embodiment, the air-conditioning outdoor unit further includes a heat exchanger 2 and a compressor 3, and the heat exchanger 2 and the compressor 3 are both arranged in a shell.

[0058] During the specific implementation, the back of the electrical box body 10 of the air conditioner indoor unit with upward air outlet is exposed under the fan blade 7 and is directly exposed to rain. In order to prevent the fan blade 7 from splashing water to the main board 13 and causing a short circuit, waterproofing is mainly performed by cooperating with the support plate 4 and the electrical box body 10. The invention point of this application: the first water receiving trough, and the hook (i.e., the fixing part 22) above it, the motor line (and cable) coming down from the top turns above the first water receiving trough and below the hook to form a local low point. The water on the motor line is gathered at the local low point under the action of gravity and drips into the water receiving trough. The second water receiving trough is formed by cooperating with the support plate through the suspended part of the electrical box (i.e., part of the structure of the waterproof component). The first water retaining edge is used to block the interior of the electrical box body from being directly connected to the outside through the first and second drainage grooves, preventing the external water from splashing directly into the electrical box body through the drainage groove. The second drain port is opened on the second water receiving trough, and the water in the first and second water receiving troughs flows out of the electrical box structure through the second drain port.

[0059] The present application solves the following technical problems: solves the risk of a small amount of rainwater flowing along the top motor wire (i.e., cable) onto the mainboard; solves the risk of a small amount of water flowing down from the top of the electrical box structure and water seeping through the screw holes (i.e., connection holes) into the electrical box structure; solves the problems of the existing glue sealing process being difficult, costly, having poor heat dissipation, and being unable to repair the glue-sealed mainboard after sales.

[0060] This application greatly enhances the waterproof reliability of the electrical box structure, improves the safety of long-term operation, and facilitates after-sales maintenance.

[0061] The present invention also provides an air conditioner, including an air conditioner outdoor unit, wherein the air conditioner outdoor unit is the air conditioner outdoor unit in the above embodiment.
