[0036] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0037] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "thickness", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a unique orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0038] In the present application, the term "exemplary" is used to mean "serving as an example, illustration, or explanation". Any embodiment described as exemplary in the present application is not necessarily to be construed as more preferred or more advantageous than other embodiments. The following description is provided to enable any person skilled in the art to implement and use the present application. In the following description, details are set forth for purposes of explanation. It should be understood that those of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles disclosed herein.

[0039] For the convenience of understanding the solution of the present application, the spline curves and arrows used in the reference numerals in the drawings are described herein: The components indicated by the spline curves without arrows are solid components, that is, components having a solid structure; the components indicated by the spline curves with arrows are virtual components, that is, components without a solid structure.

[0040] In a first aspect, please refer to Figure 1 、 Figure 2 and Figure 3 , an underfloor raceway structure 10 is provided in an embodiment of the present application. The underfloor raceway structure 10 includes an underfloor raceway having an inlet 11 and an outlet 12 which are oppositely arranged, and the inlet 11 and the outlet 12 are arranged in a staggered manner.

[0041] It should be noted that the inlet 11 and the outlet 12 are arranged in a staggered manner, that is, the orthographic projection of the inlet 11 on the plane where the outlet 12 is located and the outlet 12 do not completely overlap each other, or the orthographic projections of the outlet 12 on the plane where the inlet 11 is located do not completely overlap each other.

[0042] The wire trough structure 10 provided by this application has the inlet 11 and the outlet 12 arranged in a staggered manner. Utilizing the flexible and telescopic characteristics of the electrical wire 22, after the terminal 23 passes through the inlet 11, the electrical wire 22 bends, enabling the terminal 23 to smoothly pass through the outlet 12. Even if a finger passes through the inlet 11, it is difficult to pass through the outlet 12 and touch the power cord 31, reducing the potential risk of electric shock faced by users during use or maintenance and improving reliability and safety.

[0043] Further, in some embodiments, the wire trough structure 10 includes a housing 14, and the wire trough is formed on the housing 14. The positive projections of the inlet 11 and the outlet 12 on the plane where the housing 14 is located overlap at most partially. In other words, in some embodiments, the positive projections of the inlet 11 and the outlet 12 on the plane where the housing 14 is located may partially overlap. In other embodiments, the positive projections of the inlet 11 and the outlet 12 on the plane where the housing 14 is located do not overlap at all. When the positive projections of the inlet 11 and the outlet 12 on the plane where the housing 14 is located do not overlap at all, after entering the inlet 11, it is necessary to quickly adjust the direction and then pass through the outlet 12, effectively avoiding the situation where a finger passes through the inlet 11 and then through the outlet 12 to touch the power cord 31.

[0044] In some embodiments, please continue to refer to Figure 3 , the wire trough has a first side wall 141, a second side wall 142, a third side wall 143, and a fourth side wall 144 arranged in sequence. The first side wall 141 and the second side wall 142 are inclined and connected. The third side wall 143 and the fourth side wall 144 are inclined and connected. The first side wall 141 and the fourth side wall 144 are spaced apart to define the inlet 11, and the second side wall 142 and the third side wall 143 are spaced apart to define the outlet 12. The inlet 11 and the outlet 12 are communicated. The terminal 23 and the electrical wire 22 can smoothly enter the inlet 11 in sequence and then pass through the outlet 12, while it is difficult for a finger to enter the inlet 11 and then pass through the outlet 12.

[0045] In some embodiments, the first side wall 141, the second side wall 142, the third side wall 143, the fourth side wall 144, and the housing 14 are integrally formed. In this way, the stability of the wire trough structure 10 can be improved.

[0046] In some embodiments, the first side wall 141 and the third side wall 143 are parallel, and the second side wall 142 and the fourth side wall 144 are parallel.

[0047] Further, the positive projections of the first side wall 141 and the third side wall 143 on the plane where the housing 14 is located overlap at most partially, so that the inlet 11 and the outlet 12 are arranged in a staggered manner.

[0048] In some embodiments, the first side wall 141 and the second side wall 142 are perpendicularly arranged, and the third side wall 143 and the fourth side wall 144 are perpendicularly arranged. In other words, the first side wall 141 and the second side wall 142 are in an L shape, and the third side wall 143 and the fourth side wall 144 are in an L shape.

[0049] In some embodiments, the first side wall 141 and the third side wall 143 are arranged parallel to the plane where the housing 14 is located, and the second side wall 142 and the fourth side wall 144 are connected to the housing 14.

[0050] In some embodiments, the first side wall 141 and the third side wall 143 are spaced apart to define a wire passing opening 13, and the wire inlet 11, the wire passing opening 13, and the wire outlet 12 are sequentially communicated to form a Z-shaped wire passing groove. The terminal 23 can smoothly pass through the Z-shaped wire passing groove by bending and stretching the electrical wire 22, while it is difficult for a finger to be bent multiple times and thus cannot pass through the wire outlet 12.

[0051] In some embodiments, the wire passing groove further has a flanging 145. One end of the flanging 145 is connected to the side of the first side wall 141 away from the second side wall 142, and the other end extends towards the direction close to the third side wall 143. The flanging 145 and the first side wall 141 define the wire inlet 11. It can be understood that at this time, the flanging 145 and the fourth side wall 144 are spaced apart to define the wire inlet 11, the flanging 145 and the third side wall 143 are spaced apart to define the wire passing opening 13, and the setting of the flanging 145 shortens the size of the wire passing opening 13, further avoiding the problem of potential safety hazards when a finger passes through the wire passing opening 13 and the wire outlet 12.

[0052] Further, the flanging 145 is perpendicular to the first side wall 141 and parallel to the second side wall 142. The first side wall 141, the second side wall 142, and the flanging 145 form an inverted U-shaped structure. It should be noted that the sizes of the wire inlet 11, the wire passing opening 13, and the wire outlet 12 can be adjusted by adjusting the distance between the flanging 145 and the first side wall 141, the distance between the flanging 145 and the third side wall 143, and the distance between the third side wall 143 and the second side wall 142, so as to adapt to terminals 23 of different specifications, such that the terminals 23 can smoothly pass through the wire passing groove while fingers cannot pass through the wire passing groove, improving the reliability and safety of the wire passing groove structure 10.

[0053] The gold finger 50 is a test tool made of metal and imitating the size of a finger, which can simulate the situation of a human finger passing through the wire passing groove. Please refer to Figure 4 , in the wire passing groove structure of the related art, when using the gold finger 50 to simulate a human finger passing through the wire passing groove, since the wire inlet and the wire outlet of the wire passing groove are not misaligned, the gold finger can directly and smoothly pass through the wire inlet and the wire outlet and touch the power line, easily causing a safety accident. Please refer to Figure 5, in the wire trough structure 10 provided in the present application, due to the shielding and restriction of the first side wall 141 and the third side wall 143, the gold finger 50 cannot touch the power line 31, reducing the potential safety hazard.

[0054] Exemplarily, please refer to Figure 6 , taking the terminal 23 of the electrical structure 20 passing through the wire trough as an example, the electrical structure 20 includes an electrical component 21, an electrical wire 22, and a terminal 23 connected in sequence. The width of the inlet 11 is greater than the width of the terminal 23, so that the terminal 23 can smoothly enter the wire trough.

[0055] Please refer to Figure 7 , Figure 8 , Figure 9 and Figure 10 , the terminal 23 first enters the wire trough through the inlet 11 formed by the first side wall 141 and the fourth side wall 144, and then passes through the wire passing port 13 formed by the first side wall 141 and the third side wall 143. The front end of the terminal 23 touches one end of the third side wall 143 away from the fourth side wall 144, and the included angle with the third side wall 143 is an acute angle. The third side wall 143 generates a guiding effect, so that the terminal 23 slides relative to the third side wall 143 and continues to move forward. When sliding to contact with the fourth side wall 144, the fourth side wall 144 generates a guiding effect, and the terminal 23 slides relative to the fourth side wall 144. At this time, the electrical wire 22 is deformed, and the moving direction of the terminal 23 is slowly adjusted to be consistent with the outlet 12 formed by the third side wall 143 and the second side wall 142, and then passes through the outlet 12 smoothly.

[0056] In a second aspect, please continue to refer to Figure 1 and Figure 2 , the embodiment of the present application further provides an indoor unit, and the indoor unit includes the above-mentioned wire trough structure 10.

[0057] In some embodiments, the indoor unit includes a housing 40, the wire trough structure 10 is located on the housing 40, the indoor unit further includes an electrical box 30 and a power line 31 connected to the electrical box 30. The electrical box 30 and the power line 31 are located inside the housing 40, and the power line 31 is arranged close to the outlet 12 of the wire trough structure 10. Further, the housing 40 can be a middle frame.

[0058] In some embodiments, the indoor unit further includes an electrical structure 20, the electrical structure 20 is located outside the housing 40 and close to the inlet 11 of the wire trough structure 10. The electrical structure 20 includes an electrical component 21, an electrical wire 22, and a terminal 23 connected in sequence. The width of the inlet 11 is greater than the width of the terminal 23.

[0059] In a third aspect, the embodiment of the present application further provides an air conditioner, including the above-mentioned indoor unit.
