[0055] At present, the existing junction box 30 is installed in the bottom area of ​​the air conditioner and close to the chassis 14, or, is installed in the front area of ​​the air conditioner and close to the front panel 12; however, the wiring position is on the rear side of the air conditioner, and the installation position of the junction box 30 is not conducive to subsequent maintenance, and it is also easy to affect the routing of the wiring harness in the air conditioner.

[0056] In view of the above problems, the utility model provides an air conditioner.

[0057] See also Figures 1 to 5 In one embodiment of the utility model, the air conditioner includes a shell 10, a fresh air module 20 and a junction box 30, the shell 10 includes a back plate 11; the fresh air module 20 is arranged in the shell 10, and the fresh air module 20 includes an air outlet shell part 21; the junction box 30 is installed on the side of the air outlet shell part 21 facing the back plate 11; thereby improving the convenience of the disassembly and assembly line operation of the air conditioner.

[0058] The housing 10 includes a front panel 12, a back panel 11, a top cover 13 and a bottom plate 14. The fresh air module 20 is arranged in the housing 10, and the fresh air module 20 includes an air inlet shell 22, a fresh air duct 23 and an air outlet shell 21, wherein the fresh air duct 23 and the air inlet shell 22 are arranged along the front and rear direction of the air conditioner and are located above the bottom plate 14 of the air conditioner, and the air outlet shell 21 is arranged above the fresh air duct 23. The junction box 30 is installed on the surface of the air outlet shell 21 facing the back panel 11, compared with being arranged near the front panel 12 or near the bottom plate 14. The plate 14 is arranged to reasonably utilize the installation space between the air outlet shell part 21 and the back plate 11. On the one hand, only the back plate 11 needs to be removed to perform the disassembly and assembly line operation facing the junction box 30, thereby improving the disassembly and assembly efficiency; on the other hand, the air outlet shell part 21 is used as the installation base. Since the air outlet shell part 21 is installed at a higher position in the air conditioner, which is far away from the chassis 14 and close to the air duct component 15 and the evaporator 16, the installation height of the junction box 30 can be increased to a certain extent, which is convenient for the staff to perform the disassembly and assembly line operation in a half-squatting posture or sitting posture, thereby improving the convenience of disassembly and assembly.

[0059] The junction box 30 is detachably connected to the air outlet shell 21 , and the connection methods include but are not limited to bolt connection, inlay connection, and plug-in fit, so that the junction box 30 can be easily disassembled and assembled according to the needs.

[0082] The inlet groove 3241 and the outlet groove 3242 are respectively provided on the two box side panels 324. Of course, in other embodiments, the inlet groove 3241 and the outlet groove 3242 are provided on the same box side panel 324. When the box body 32 and the box cover 31 are connected, the box cover 31 can prevent the input wire harness 42 and the output wire harness 41 from being separated from the junction box 30; the cover side panel of the box cover 31 is located on the outside of the box side panel 324 to hide the connection between the box body 32 and the box cover 31.

[0083] See also Figure 7 and Fig.11 In the embodiment of the utility model, a clamping foot 341 and a clamping hole 3212 for clamping engagement are provided between the wire clamp 34 and the box substrate 321 , which can prepare for further assembly of the wire clamp 34 and the box substrate 321 .

[0084] Among them, there are multiple clamping feet 341, and the extension directions of the free ends of at least two of the clamping feet 341 are opposite. The clamping feet 341 are arranged at intervals along the left and right directions of the junction box 30. When the wire clamp 34 is clamped with the edge of the clamping hole 3212 through the clamping feet 341, since the free ends of the two clamping feet 341 extend in opposite directions, the displacement of the wire clamp 34 in the left and right directions and the front and back directions is restricted, which effectively prevents the wire clamp 34 from detaching from the box substrate 321, thereby improving the assembly reliability of the wire clamp 34.

[0085] Because the free ends of the two clamping feet 341 extend in opposite directions, in order to ensure the smooth assembly of the wire clamp 34, in an embodiment of the utility model, the free end of the clamping foot 341 is provided with a guiding inclined surface 3411 for guiding the deformation of the clamping foot 341. Then, when pressure is applied to the wire clamp 34, one clamping foot 341 passes through the corresponding clamping hole 3212, and the guiding inclined surface 3411 of the other clamping foot 341 first abuts against the edge of the other clamping hole 3212. Moreover, because the clamping foot 341 is deformable, the clamping foot 341 is deformed and pressed into the clamping hole 3212 by utilizing the avoidance and guidance of the guiding inclined surface 3411, thereby completing the assembly of the wire clamp 34.

[0086] In order to strengthen the connection between the wire clip 34 and the box base plate 321, in the embodiment of the present utility model, the wire clip 34 and the box base plate 321 are further connected by a fastener 60. Of course, in other embodiments, the wire clip 34 and the box base plate 321 are only connected by the fastener 60 or the clamping foot 341.
