The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] The present invention provides a wire-passing structure, please refer to Figures 1 to 5 , installed between the electrical box 1 and the junction box 2 of the air conditioner indoor unit, used to guide the wires between the electrical box 1 and the junction box 2, the junction box 2 is installed on the box body of the electrical box 1, and the wire-passing structure includes: a wire-passing body 10; a first wire-passing portion 20, the first wire-passing portion 20 is arranged on the wire-passing body 10, at least part of the first wire-passing portion 20 is installed at the first wire-passing opening 11 of the electrical box 1, so as to limit the wire located at the first wire-passing opening 11; a second wire-passing portion 30, the second wire-passing portion 30 is arranged on the wire-passing body 10, at least part of the second wire-passing portion 30 is installed at the second wire-passing opening 21 of the junction box 2, so as to limit the wire at the second wire-passing opening 21, so that the wire extending from the first wire-passing opening 11 passes through the first wire-passing portion 20 and the second wire-passing portion 30 in sequence and then enters the junction box 2; a shielding plate 40, the shielding plate 40 is connected to the wire-passing body 10, and at least part of the shielding plate 40 is located above the electrical box 1 to shield the connection gap between the electrical box 1 and the junction box.

[0033] The wire-passing structure provided by the present invention is installed between the electrical box 1 and the junction box 2 of the air-conditioning indoor unit, and is used to guide the wires between the electrical box 1 and the junction box 2. The junction box 2 is installed on the box body of the electrical box 1. The wire-passing structure includes a wire-passing body 10, a first wire-passing portion 20, a second wire-passing portion 30 and a shielding plate 40. The first wire-passing portion 20 is arranged on the wire-passing body 10, and at least a portion of the first wire-passing portion 20 is installed at the first wire-passing opening 11 of the electrical box 1 to limit the wire located at the first wire-passing opening 11. The second wire-passing portion 30 is arranged on the wire-passing body 10, and at least a portion of the second wire-passing portion 30 is installed at the second wire-passing opening 21 of the junction box 2 to limit the wire at the second wire-passing opening 21, so that the wire extending from the first wire-passing opening 11 passes through the first wire-passing portion 20 and the second wire-passing portion 30 in sequence and then enters the junction box 2, and the shielding plate 40 is provided. The baffle 40 is connected to the wire-passing body 10, and at least a portion of the baffle 40 is located above the electrical box 1 to shield the connection gap between the electrical box 1 and the junction box 2. During the installation of the electrical box 1, the electrical box 1 has a box body and a cover body, and a connection gap will be left after the box body and the cover body are connected. The condensed water on the air-conditioning indoor unit will drip onto the connection gap along the electrical box 1 and flow into the electrical box 1. At the same time, since the junction box 2 is installed on the electrical box 1, there will also be a connection gap between the junction box 2 and the electrical box 1. The condensed water will flow into the junction box 2 through the gap between the junction box 2 and the electrical box 1, causing a safety hazard in electricity use. By providing the baffle 40, the connection gap is shielded to prevent condensed water from dripping into the electrical box and / or the junction box 2, thereby ensuring the safety of electricity use of the electrical box and solving the problem of low safety level of the electrical box component of the air-conditioning indoor unit in the prior art.

[0034] Specifically, Figure 3 As shown, a collection groove 41 is provided on the baffle plate 40, so that the condensed water on the air-conditioning indoor unit falls onto the baffle plate 40 and flows into the collection groove 41 for collection; a return water port 42 is also provided on the baffle plate 40, and the return water port 42 is connected with the collection groove 41, so that the condensed water in the collection groove 41 flows out through the return water port 42. This arrangement facilitates the centralized treatment of the condensed water.

[0035] In the specific implementation, since there is a wire connected to the power supply in the electrical box 1, it needs to be led out from the electrical box 1 and pass through the return water bend formed between the electrical box 1 and the panel of the air-conditioning indoor unit. Therefore, in order to prevent the wire from contacting the condensed water at the return water bend and causing a safety accident, the wire is clamped by a wire clamp to limit the wire. Therefore, a mounting seat 43 for installing the wire clamp is provided on the baffle plate 40. The wire clamp is used to clamp the wire led out from the electrical box 1 to the power supply. The mounting seat 43 is provided with a mounting hole, and at least a part of the wire clamp is installed in the mounting hole. This arrangement facilitates the installation of the wire clamp and makes it convenient for the wire clamp to clamp the wire.

[0036] In the embodiments provided by the present invention, Figure 2 As shown, the second wire-passing portion 30 includes: a first connecting member 31, and a mounting groove 310 is provided on the body of the first connecting member 31, so that the side wall portion forming the second wire-passing opening 21 of the junction box 2 is inserted into the mounting groove 310, so that the second wire-passing portion 30 is installed on the junction box 2, and the installation of the wire-passing structure is simpler and more convenient through the snap-on connection method.

[0037] Specifically, a wire passing rib 311 is further provided on the body of the first connecting member 31 , and at least a portion of the wire passing rib 311 protrudes toward the middle of the second wire passing opening 21 , so that the wire passes through the wire rib 311 and enters the junction box 2 .

[0038] There are two first connecting members 31, and the two first connecting members 31 are arranged opposite to each other to form a wire passing gap between the two wire passing ribs 311 for the wire to pass through. By setting the two wire passing ribs 311, the size of the wire passing gap can be reduced, and the space after the wire passes through the wire passing gap can be reduced, thereby preventing small animals such as mice from entering the junction box 2 through the wire passing gap and damaging internal components.

[0039] like Figure 4 As shown, the first wire-passing portion 20 includes: a limiting boss 201, at least a portion of the limiting boss 201 is installed at the first wire-passing opening 11; a wire-passing component 202, at least a portion of the wire-passing component 202 is installed on the limiting boss 201, so that the limiting boss 201 and the side panel of the electrical box 1 stop each other to limit the wire-passing component 202, to prevent the wire-passing component 202 from being unstable at the first wire-passing opening 11, and to prevent the wire-passing component 202 from moving when passing the wire by the limiting boss 201, and the wire-passing component 202 has a wire-passing gap 2022 for the wire to pass through.

[0040] Preferably, the wire passing assembly 202 includes a plurality of ribs 2021 arranged in parallel, and two adjacent ribs 2021 are arranged at intervals. The ribs 2021 are preferably soft ribs to prevent the wire skin from being cut when the wire passes through. At the same time, by arranging a plurality of ribs 2021 in parallel, the remaining space of the wire passing gap 2022 after the wire passes is reduced, which is sufficient to prevent insects and rodents.

[0041] In a specific implementation, a plurality of ribs 2021 are divided into two groups, and the two groups of ribs 2021 are arranged relative to each other to form a wire passing gap 2022 between the two groups of ribs 2021. The wire passing assembly 202 also includes: a pressed opening 2023, which is connected to the wire passing gap 2022, and the pressed opening 2023 gradually widens in a direction away from the ribs 2021, wherein the pressed opening 2023 is in an eight-shaped shape, and the smaller end of the eight-shaped opening is close to the wire passing gap 2022. By setting the pressed opening 2023, the wire can be guided when the wire is pressed in.

[0042] Furthermore, the wire passing assembly 202 includes: a retaining ring 2024, which is installed on the limiting boss 201, and a wire passing opening 2025 is provided on the retaining ring 2024, and the wire passing opening 2025 is connected to the wire passing gap 2022, so that the wire can be guided to the second wire passing part 30 through the wire passing opening 2025 after passing through the wire gap 2022.

[0043] like Figure 3 and Figure 4 As shown, the wire passing structure further includes: a guide channel 50, which is arranged between the first wire passing portion 20 and the second wire passing portion 30, so that the wire is guided along the guide channel 50 to the second wire passing portion 30 after passing through the first wire passing portion 20.

[0044] The guide channel 50 has a first side wall and a second side wall that are arranged opposite to each other; a limit block 51 is arranged in the guide channel 50, and the limit block 51 is arranged on the first side wall to form a limit space between the limit block 51 and the second side wall for pressing the wire; in the process of routing, the wire passes through the first wire passing portion 20, the guide channel 50 and the second wire passing portion 30 in sequence, and the routing path of the wire is bent, which makes it easy for the wire to warp. Therefore, by setting the limit block 51 in the guide channel 50 and pressing the wire between the limit block 51 and the second side wall, the problem of wire warping can be effectively solved, making the routing more regular, without the need to set a separate wire pressing structure, and saving materials.

[0045] Preferably, the baffle plate 40 is arranged on the side of the first wire-passing portion 20, the baffle plate 40 extends along a first predetermined direction, and the guide channel 50 extends along a second predetermined direction, and the first predetermined direction is perpendicular to the second predetermined direction, so that the baffle plate 40 can completely block the connection gap on the electrical box 1 and the middle gap after the electrical box and the junction box cover are assembled. Preferably, the baffle plate 40, the wire-passing body 10 and the guide channel 50 are an integrated structure, which can be directly assembled with the electrical box and the junction box, and reduces the number of personnel on the final assembly line, greatly improving the assembly efficiency of the final assembly.

[0047] The present invention further provides an air conditioner indoor unit, comprising an electrical appliance box assembly, wherein the electrical appliance box assembly is the electrical appliance box assembly of the above embodiment.

[0048] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

The condensed water will flow into the junction box 2 through the gap between the junction box 2 and the electrical box 1, causing a safety hazard in electricity use. By providing the baffle 40, the connection gap is shielded to prevent condensed water from dripping into the electrical box and / or the junction box 2, thereby ensuring the safety of electricity use of the electrical box and solving the problem of low safety level of the electrical box component of the air-conditioning indoor unit in the prior art.
