[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] The following combination Figures 1 - 3 An electric control box according to an embodiment of the present invention is described.

[0028] The electric control box of the present embodiment includes a box body 1, an electric control board, and a wiring harness 2. The box body 1 has a receiving cavity and comprises a first side panel 11, a slanted panel 12, and a second side panel 13, which are connected in sequence. The first side panel 11 is perpendicular to the second side panel 13, and the side of each of the first side panel 11 and the second side panel 13 facing the receiving cavity forms an obtuse angle with the side of the slanted panel 12 facing the cavity. The electric control board is mounted within the receiving cavity. The wiring harness 2 is mounted on the side of the slanted panel 12 facing away from the receiving cavity.

[0029] According to the electric control box of the embodiment of the present utility model, the box body 1 has a receiving cavity. For each of the first side plate 11 and the second side plate 13 in the box body 1, the side facing the receiving cavity forms an obtuse angle with the side of the inclined plate 12 facing the receiving cavity. The wire harness 2 is installed on the side of the inclined plate 12 facing away from the receiving cavity. At this time, at least part of the fixed wire harness 2 overlaps with the inclined plate 12 in the thickness direction of the first side plate 11 and overlaps with the inclined plate 12 in the thickness direction of the second side plate 13. Furthermore, the maximum dimension of the electric control box in the thickness direction of the first side plate 11 and the maximum dimension in the thickness direction of the second side plate 13 can be designed to be smaller. Thus, the internal space of the air conditioner occupied by the electric control box is effectively reduced, and there is no need to increase or excessively increase the volume of the air conditioner, and the manufacturing cost of the air conditioner is lower.

[0030] It should be noted that the thickness direction of the first side plate 11 is the width direction of the box body 1, and the thickness direction of the second side plate 13 is the length direction of the box body 1. The maximum length and width of the electric control box in this embodiment are closer to the length and width of the box body 1. Compared with the box body 1 with a cuboid outer contour in the related art, on the basis of not affecting the electric control board in the receiving cavity, part of the box body 1 is set to be concave inward to reduce the gap of the receiving cavity, and then the inclined plate 12 as described above is formed.

[0031] In some embodiments, the thickness direction of the electric control board is the same as the thickness direction of the first side plate 11. The electric control board is provided with a high-voltage area and a low-voltage area arranged along the thickness direction of the second side plate 13. The inclined plate 12 is arranged opposite to the low-voltage area in the thickness direction of the first side plate 11.

[0032] The electric control board includes a substrate and components installed on the substrate. The size of the components located in the high-voltage area in the thickness direction of the first side plate 11 is larger than the size of the components located in the low-voltage area in the thickness direction of the first side plate 11. Thus, at the position opposite to the low-voltage area, the concave amplitude of the box body 1 can be made larger to form an inclined plate 12 with a larger distribution area. At this time, the maximum dimensions of the inclined plate 12 in the length direction and width direction of the box body 1 are larger, and thus the wire harness 2 can be better hidden.

[0033] Specifically, the extending direction of the wire harness 2 installed outside the inclined plate 12 is parallel to the substrate of the electric control board. The wire harness 2 includes a power line and an internal and external machine connection line, and both extend into the receiving cavity and are electrically connected to the electric control board.

[0034] In some embodiments, the electric control box further includes a wire clip 3. The wire clip 3 is arranged on the side of the inclined plate 12 facing away from the receiving cavity, and the wire harness 2 is fixed on the wire clip 3.

[0035] The setting of the wire clip 3 not only facilitates the reliable fixation of the wire harness 2 outside the inclined plate 12, but also realizes the sorting of the wire harness 2, avoiding the wire harness 2 from being too messy at the inclined plate 12.

[0036] Specifically, after the wire harness 2 is led out of the accommodating cavity, the wire harness 2 can be fixed by snapping or screwing to restrict the routing direction of the wire harness 2.

[0037] In some embodiments, as Figure 3 As shown, on a projection plane perpendicular to the thickness direction of the first side plate 11, the projection of the wire clamp 3 is located within the projection of the inclined plate 12. And / or, on a projection plane perpendicular to the thickness direction of the second side plate 13, the projection of the wire clamp 3 is located within the projection of the inclined plate 12.

[0038] At this time, the maximum dimension of the electric control box in the thickness direction of the second side panel 13 is the dimension (length) of the box body 1 in the thickness direction of the second side panel 13, and / or, the maximum dimension of the electric control box in the thickness direction of the first side panel 11 is the dimension (width) of the box body 1 in the thickness direction of the first side panel 11, thereby further reducing the volume of the electric control box, making it occupy less space inside the air conditioner, and lowering the production cost of the air conditioner.

[0039] Specifically, the height dimension of the electric control box is also the height dimension of the box body 1. At this time, when the wire harness 2 is fixed on the wire clamp 3, the wire clamp 3 wraps the wire harness 2, and the wire harness 2 does not increase the length and width dimensions of the electric control box.

[0040] In some embodiments, as Figure 1 As shown, the wire clamp 3 includes a base 31 and a clamping plate 32, wherein the base 31 is connected to the inclined plate 12. The clamping plate 32 is detachably connected to the base 31, and the wire harness 2 is clamped between the clamping plate 32 and the base 31.

[0041] When fixing the wire harness 2, press the wire harness 2 against the side of the base 31 away from the inclined plate 12, and then connect the clamping plate 32 to the base 31 to fix the wire harness 2 on the wire clamp 3. The installation of the wire harness 2 is simple and convenient.

[0042] Specifically, the splint 32 may be movably and detachably connected to the base 31 , or may be pivotally connected to the base 31 at one end and screwed or clamped to the base 31 at the other end.

[0043] In some embodiments, as Figure 1 and Figure 2 As shown, the base 31 is provided with a threaded hole 312, and the clamping plate 32 is provided with a mounting hole 321. The clamping plate 32 is connected to the base 31 via a threaded member that passes through the mounting hole 321 and threadedly engages with the threaded hole 312. The base 31 is provided with a positioning post 311, and the clamping plate 32 has a positioning hole on the side facing the base 31. The positioning hole is a special-shaped hole, and the cross-sectional outer contour of the positioning hole matches the cross-sectional outer contour of the positioning post 311.

[0044] That is, the splint 32 is connected to the base 31 through a screw to fix the wiring harness 2. The connection strength between the splint 32 and the base 31 is high, and the splint 32 is not easy to loosen. On this basis, the positioning column 311 is plugged into the positioning hole to effectively ensure the relative fixation of the splint 32 and the base 31 in the circumference of the positioning hole. At this time, only one screw needs to be set to complete the reliable installation of the splint 32 on the base 31, and the installation efficiency of the splint 32 on the base 31 is high.

[0045] Specifically, the axial direction of the positioning column 311 is consistent with the axial direction of the threaded hole 312. The threaded hole 312 is arranged on the outer end face of the positioning column 311. The positioning hole is a blind hole. The bottom face of the positioning hole is provided with a mounting hole 321 that passes through the clamp 32. Compared with the separate setting of the threaded hole 312 and the positioning column 311, this setting further reduces the volume of the wire clamp 3, thereby effectively avoiding the wire clamp 3 being too large and occupying too much space inside the air conditioner.

[0046] In some embodiments, as Figure 2 and Figure 3 As shown, at least one of the base 31 and the clamping plate 32 is provided with a limiting groove 313 for the wiring harness 2 to cooperate with. The limiting groove 313 extends along a first direction, which is orthogonal to the thickness direction of the first side plate 11 and the thickness direction of the second side plate 13.

[0047] The limiting groove 313 limits the wiring harness 2 in the width direction of the limiting groove 313, effectively preventing the fixed wiring harness 2 from being deflected relative to the first direction when pulled by external force, thereby affecting the routing direction of the wiring harness 2.

[0048] like Figure 2 As shown, there are two limit grooves 313 corresponding to the power cord and the internal and external unit connection wires respectively. The limit groove 313 is arranged on the side of the base 31 away from the inclined plate 12. The inner wall surface of the limit groove 313 can be provided with multiple horizontal plates arranged at intervals along its extension direction. The horizontal plates effectively increase the friction between the wiring harness 2 and the base 31 in the first direction, thereby further ensuring the reliability of the fixation of the wiring harness 2 on the wire clamp 3.

[0049] In some embodiments, as Figure 2 and Figure 3As shown in the figure, the box body 1 further includes a third side plate 14. The third side plate 14 is perpendicular to the first side plate 11 and parallel to the second side plate 13. The third side plate 14 is connected to the end of the first side plate 11 away from the inclined plate 12, and the third side plate 14 forms a part of the inner wall surface of the accommodation cavity. On the side of the third side plate 14 facing the second side plate 13, a first guide groove 141 is provided. On the side of the second side plate 13 facing the third side plate 14, a second guide groove 131 is provided. The extending directions of the first guide groove 141 and the second guide groove 131 are both orthogonal to the thickness directions of the first side plate 11 and the second side plate 13. The two opposite ends of the electronic control board along the thickness direction of the second side plate 13 are respectively inserted into the first guide groove 141 and the second guide groove 131.

[0050] That is, the electronic control board can be inserted into the accommodation cavity along the extending direction of the first guide groove 141, and the substrate of the electronic control board is inserted into the first guide groove 141 and the second guide groove 131, thereby realizing the installation of the electronic control board in the accommodation cavity, and the installation of the electronic control board is convenient.

[0051] Specifically, the box body 1 further includes a fourth side plate 16 that forms a part of the inner wall surface of the accommodation cavity. The fourth side plate 16 is parallel to the first side plate 11 and connects the second side plate 13 and the third side plate 14. The electronic control board is spaced apart from the first side plate 11 and the fourth side plate 16 along the thickness direction of the first side plate 11.

[0052] In some embodiments, as Figure 1 shown, the box body 1 further includes a cover plate 15. The cover plate 15 is detachably connected to at least one of the first side plate 11 and the second side plate 13. A wire passing hole 121 communicating with the accommodation cavity is defined between the cover plate 15 and the inclined plate 12.

[0053] Thus, the cover plate 15 can be detached to facilitate the installation of the electronic control board in the accommodation cavity. By detachably connecting the cover plate 15 to at least one of the first side plate 11 and the second side plate 13, while realizing the closure of the accommodation cavity, a wire passing hole 121 for the wire harness 2 to extend out of the accommodation cavity is also formed. The arrangement of the wire passing hole 121 beside the inclined plate 12 effectively facilitates the fixing of the wire harness 2 on the inclined plate 12.

[0054] Specifically, the cover plate 15 can be snap-connected to the second side plate 13 and the third side plate 14 to realize the assembly of the box body 1.
