[0037] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0038] See Figures 1 to 5This utility model provides an indoor unit 1, which includes a middle frame 10 and an air guide assembly 20. The middle frame 10 is provided with an air outlet 11, and a first wiring hole 14 is provided at the part of the middle frame 10 corresponding to the air outlet 11. A first sidewall 12 is provided at the upper edge of the middle frame 10, and the first wiring hole 14 is provided on the first sidewall 12. The air guide assembly 20 is provided at the air outlet 11. One end of the air guide assembly 20 is provided with a receiving chamber for installing a first drive assembly, and a second wiring hole 221 is provided in the receiving chamber near the first wiring hole 14. There is also a gap 15 between the air guide assembly 20 and the middle frame 10, and the second wiring hole 221 communicates with the gap 15. The motor wire of the first drive assembly passes through the second wiring hole 221 and the first wiring hole 14 in sequence to connect to the electrical control box provided in the middle frame 10. The electrical control box is located on the inner side of the first sidewall 12. By placing the first wiring hole 14 on the middle frame 10 near the air outlet 11, the motor wire can be directly connected to the control box after passing through the first wiring hole 14, without having to take a long detour, thus reducing the distance of the motor wire, optimizing the wiring inside the indoor unit 1, and saving materials.

[0039] Furthermore, during the intermediate process from the first wire hole 14 to the second wire hole 221, the motor wire can be selected to pass through the gap 15 between the drive motor and the middle frame 10, so that the path of the motor wire is shortened to the greatest extent. On the other hand, setting the gap 15 between the air guide assembly 20 and the side of the middle frame 10 can utilize the structure of the indoor unit 1 itself, thereby saving space.

[0040] Specifically, the first wiring hole 14 is located on the middle frame 10 near the electrical control box. The motor wire can be directly connected to the electrical control box after passing through the first wiring hole 14. By placing the first wiring hole 14 near the electrical control box, the complexity of the motor wire routing inside the middle frame 10 can be further reduced, thereby reducing the impact of the motor wire on the internal components of the indoor unit 1.

[0041] Preferably, a wire clamping component 31 is provided on the inner side of the middle frame 10, and the wire clamping component 31 is arranged opposite to the first wire bundling hole 14; wherein, the second wire bundling hole 221, the gap 15, the first wire bundling hole 14, and the wire clamping component 31 constitute a wire bundling structure for passing wires. In addition, an adapter plate 30 is provided on the inner side of the middle frame 10, and the wire clamping component 31 is disposed on the adapter plate 30. The adapter plate 30 is installed inside the indoor unit 1, and the adapter plate 30 and the wire clamping component 31 are respectively attached to two different side walls of the middle frame 10, so that the adapter plate 30 is more securely installed in the indoor unit 1 and saves internal space of the indoor unit 1. By providing the wire clamping component 31 opposite to the first wire bundling hole 14 inside the indoor unit 1, the routing of the motor wires inside the indoor unit 1 is further constrained, making the motor wires inside the indoor unit 1 less prone to tangling and easier to manage internal wiring.

[0042] Specifically, the wire clamp 31 is coiled, with a long, coiled arm similar to a mosquito coil. Correspondingly, it also has a coiled channel similar to a mosquito coil. The innermost part of the wire clamp 31 has a wire passage 32 for restraining the motor wire. The wire passage 32 is positioned opposite the first bundle of wires, allowing the motor wire to directly enter through the first bundle of wires. By designing the wire clamp 31 as a coiled shape, on one hand, the motor wire can enter the innermost wire passage 32 through the coiled channel. Once restrained by the wire clamp 31, the wire is less likely to detach from the clamp due to its coiled channel, preventing tangled wiring. On the other hand, due to the shape limitation of the wire clamp 31, the restraint space decreases towards the innermost part, which is more conducive to restraining the motor wire.

[0043] Furthermore, a second sidewall 13 connected to the first sidewall 12 is provided on one side of the air outlet 11. The second sidewall 13 is arranged perpendicularly to the first sidewall 12. The air guide assembly 20 includes an air guide 23 and a motor cover 22. The air guide 23 is located on the outside of the second sidewall 13 inside the air outlet 11. One end of the air guide 23 is provided with a motor compartment 21. The receiving chamber is opened in the motor compartment 21, thereby installing the drive assembly in the motor compartment 21. The opening of the motor compartment 21 is directly opposite the second side wall 13 to allow the drive motor to be mounted on the inner frame 10 of the indoor unit 1. A motor cover 22 is located on the motor compartment 21, with a gap 15 between the motor cover 22 and the second side wall 13 of the inner frame 10, allowing the motor wire to pass through the gap 15. A second wiring hole 221 is located on the motor cover 22, and the motor wire of the drive motor extends from the motor compartment 21, passes through the gap 15 between the motor cover 22 and the second side wall 13, and then connects to the first wiring hole 14 on the first side wall 12. This arrangement ensures that, on the one hand, the motor cover 22, located between the motor compartment 21 and the second side wall 13, is less likely to fall off, improving the stability of the air guide assembly 20 when mounted on the indoor unit 1; on the other hand, the second wiring hole 221 is close to the gap 15, allowing for direct connection and shortening the path of the first wiring channel.

[0044] Preferably, the indoor unit 1 further includes a second drive assembly, which is installed inside the middle frame 10 at a position corresponding to the air guide assembly 20;

[0045] An adapter plate 30 is sandwiched between the second drive assembly and the second side wall 13, and the adapter plate 30 has a small hole through which the motor shaft passes. In addition, a first shaft hole 16 is provided on the second side wall 13 of the middle frame 10, through which the motor shaft passes and connects to the air guide assembly 20. The motor shaft is hexagonal to facilitate driving the air guide assembly 20 when the motor shaft rotates. This arrangement allows the second drive assembly to directly control the rotation of the air guide assembly 20 through the first shaft hole 16 on the middle frame 10; and reduces further contact between the air guide assembly 20 and the middle frame 10, thereby reducing interference to the air guide assembly 20 and making the operation of the air guide assembly 20 smoother.

[0046] Specifically, a bearing seat 211 is provided on the side of the motor housing 21 near the second drive assembly. The bearing seat 211 is located at the edge of the motor housing 21 and passes through the motor cover 22 to engage with the motor shaft. The bearing seat 211 has a second shaft hole 212 for engaging with the motor shaft. Correspondingly, the second shaft seat 211 is hexagonal to facilitate engagement between the motor shaft and the second shaft seat 211. The bearing seat is located between the side wall of the motor housing and the air outlet. By using the second shaft hole 212 to engage with the motor shaft, the stability of the motor shaft is improved, and the motor housing 21 and the motor shaft are easily disassembled.

[0047] On the other hand, the motor cover 22 has a notch 222, which is also located at the edge of the motor housing 21. This allows the shaft seat 211 to engage with the motor shaft through the motor cover 22, and the notch 222 and the shaft seat 211 are tightly fitted together. This ensures that the motor cover 22 covers the motor housing 21 as much as possible, preventing the internal drive motor from being exposed. By providing the notch 222 in the motor cover 22 for the shaft seat 211 to pass through, the motor shaft can be directly connected to the shaft seat on the motor housing 21, facilitating installation.

[0048] Preferably, the motor cover 22 is further provided with a narrow opening 223 for connecting the notch 222 and the second wire harness hole 221. The narrow opening 223 is smaller than the second wire harness hole 221 and the notch 222 to restrict the movement space of the motor wire in the second wire harness hole 221. By using the narrow opening 223 to connect the second wire harness hole 221 and the notch 222, it is convenient for the motor wire to enter the second wire harness hole 221 from the notch 222, which facilitates installation. Moreover, this integrated design facilitates industrial manufacturing.

[0049] In addition, the motor housing 21 has several fixing protrusions 213 distributed around its periphery; the motor cover 22 has several fixing clips 224 that cooperate with the fixing protrusions 213, so that the motor cover 22 is snapped onto the motor housing 21. By distributing the fixing protrusions 213 and fixing clips 224 evenly around the periphery as much as possible, the stability of the motor cover 22 when fixed onto the motor housing 21 is further improved. Through the cooperation of the fixing protrusions 213 and fixing clips 224, the motor cover 22 can be more stably installed on the motor housing 21, making it less likely to fall off.

[0050] This utility model also provides an air conditioner, which includes an indoor unit 1 of any of the above-mentioned features; wherein, the first wire harness hole 14 is located on the upper side of the inner wall of the middle frame forming the air outlet 11, and the hole axis of the first wire harness hole 14 is perpendicular to the hole axis of the second wire harness hole 221. Through this positional relationship, the air guide assembly 20 is conveniently installed at the air outlet 11, while the path of the motor wire is shortened.

[0051] Although the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
