[0041] Compared with the prior art, the beneficial effects of this utility model are:

[0042] In the technical solution of this utility model, the electrical control box assembly includes a first housing, a circuit board, and a wire assembly. The first housing has a first opening and a second opening. The circuit board is disposed inside the first housing and has a first terminal and a second terminal. The wire assembly includes a first wire harness and a second wire harness.

The high-voltage wire harness (first wire harness) and the low-voltage wire harness (second wire harness) of the electrical control box assembly are respectively led out of the first housing from different openings (i.e., the first opening and the second opening). Compared with the related technology where the high-voltage wire harness and the low-voltage wire harness are combined and led out from the same opening of the housing, in this solution, the high-voltage wire harness and the low-voltage wire harness are set separately, reducing their electromagnetic interference.

[0074] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0075] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0076] The electrical control box assembly includes a housing and a circuit board disposed within the housing. The circuit board is electrically connected to a high-voltage wiring harness and a low-voltage wiring harness, respectively. The low-voltage wiring harness can be used to electrically connect sensors or display components, while the high-voltage wiring harness can be used to electrically connect a power supply or a drive motor. In one embodiment of the related technology, the high-voltage and low-voltage wiring harnesses of the electrical control box assembly exit the housing through the same opening; in another embodiment, two openings are provided on the same side plate of the housing, one opening leading to the high-voltage wiring harness and the other opening leading to the low-voltage wiring harness. In the above solutions, the high-voltage and low-voltage wiring harnesses are relatively close together, which can easily lead to EMC interference between them, affecting the electrical control performance.

[0077] In view of this, see Figure 1 - Figure 13 In some embodiments of this application, an electrical control box assembly 10 is provided. This electrical control box assembly 10 is used for the indoor unit 1 of an air conditioner. The electrical control box assembly 10 can be used for wall-mounted or floor-standing units. In this embodiment, see [link to relevant documentation]. Figure 1 - Figure 4 The electrical control box assembly 10 is used for the wall-mounted unit. Specifically, the electrical control box assembly 10 includes a first housing 100, a circuit board 200, and a wiring assembly 300.

[0078] See Figure 5 - Figure 9 The first housing 100 is composed of multiple side plates, which together enclose a first receiving cavity 150. The number of side plates of the first housing 100 depends on its actual shape. For example, when the space enclosed by the outer wall of the first housing 100 is approximately a quadrangular prism (i.e., the first housing 100 is approximately a rectangular box), it has six sides, and the first housing 100 has six side plates. When the space enclosed by the outer wall of the first housing 100 is approximately a pentagonal prism, the first housing 100 has seven sides, and the first housing 100 has seven side plates. It should be noted that the boundaries of each side plate are defined by the position of each plate, not by the connection relationship between the plates. In other words, even if two plates located on different sides of the first housing 100 are connected as one unit, since the two plates are located on opposite sides of the first housing 100, these two plates are still referred to as two side plates, not a single side plate.

[0079] See Figure 5 - Figure 13The first housing 100 includes a first side plate 110 and a second side plate 120 located on different sides. The first side plate 110 has a first opening 111 communicating with a first receiving cavity 150, and the second side plate 120 has a second opening 123 communicating with the first receiving cavity 150. It should be noted that the first side plate 110 and the second side plate 120 are two of the various side plates of the first housing 100, and their respective arrangements and relative arrangements can be adjusted according to actual needs. In some embodiments, the first side plate 110 and the second side plate 120 can be located on opposite sides of the first housing 100. For example, when the first side plate 110 is the upper side plate of the first housing 100, the second side plate 120 is the lower side plate of the first housing 100; when the first side plate 110 is the front side plate of the first housing 100, the second side plate 120 is the rear side plate of the first housing 100. In other embodiments, see... Figure 9 The first side plate 110 and the second side plate 120 are located on adjacent sides of the first housing 100 and are connected to each other. Specifically, the first housing 100 has a first direction X and a second direction Y that are intersecting each other. The first side plate 110 is located on one side of the first housing 100 along the first direction X, and the second side plate 120 is located on one side of the first housing 100 along the second direction Y. One side of the first side plate 110 is connected to the second side plate 120. For example, see [link to example]. Figure 9 In some embodiments, the first side plate 110 and the second side plate 120 are located on adjacent sides of the first housing 100, and according to Figure 9 As shown, the first side plate 110 is the lower side plate of the first housing 100, and the second side plate 120 is the left side plate of the second housing 500. See also Figure 10 as well as Figure 11 In other embodiments, the first side plate 110 and the second side plate 120 are located on adjacent sides of the first housing 100, and according to Figure 10 as well as Figure 11 As shown, the first side plate 110 is the lower side plate of the first housing 100, and the second side plate 120 is the front side plate of the first housing 100.

[0080] For ease of description, the following will use Figure 5 - Figure 9 The illustrated embodiment is provided as an example. In this embodiment, the first side plate 110 and the second side plate 120 are located on adjacent sides of the first housing 100, and are arranged in a manner that... Figure 9 As shown, the first side plate 110 is the lower side plate of the first housing 100, and the second side plate 120 is the left side plate of the second housing 500. In this embodiment, the front side plate is the third side plate 130.

[0081] See Figure 5 - Figure 9The circuit board 200 is disposed in the first receiving cavity 150. The circuit board 200 has a first terminal 210 and a second terminal 220, wherein the first terminal 210 is a high-voltage terminal and the second terminal 220 is a low-voltage terminal. It should be noted that, in this application, the output power or input power of the high-voltage terminal is higher than that of the low-voltage terminal. The voltage at the high-voltage terminal can be higher than or equal to 220 volts, and the voltage at the low-voltage terminal can be between a few volts and tens of volts. Furthermore, the circuit board 200 may include one or more high-voltage terminals, and the circuit board 200 may include one or more low-voltage terminals. See also... Figure 8 - Figure 9 In this embodiment, the circuit board 200 includes two high-voltage terminals and two low-voltage terminals. One high-voltage terminal is a first terminal 210, and the other high-voltage terminal is a third terminal 230; one low-voltage terminal is a second terminal 220, and the other low-voltage terminal is a fourth terminal 240.

[0082] See Figure 5 - Figure 9 The wire assembly 300 includes a first wire harness 310 and a second wire harness 320. The first wire harness 310 is electrically connected to a first terminal 210 and passes through a first opening 111. Since the first terminal 210 is a high-voltage terminal, the first wire harness 310 is a high-voltage wire harness. The second wire harness 320 is electrically connected to a second terminal 220 and passes through a second opening 123. Since the second terminal 220 is a low-voltage terminal, the second wire harness 320 is a low-voltage wire harness. The wire assembly 300 may include only the first wire harness 310 and the second wire harness 320, or it may include other wire harnesses besides the first wire harness 310 and the second wire harness 320. Each wire harness of the wire assembly 300 may each include one wire or multiple wires. In this embodiment, the wire assembly 300 also includes a third wire harness 330 and a fourth wire harness 340. The third wire harness 330 is electrically connected to the third terminal 230, making the third wire harness 330 a high-voltage wire harness; the fourth wire harness 340 is electrically connected to the fourth terminal 240, making the fourth wire harness 340 a low-voltage wire harness.

[0083] It should be noted that, depending on the naming convention, the relative positions of the first terminal 210, the second terminal 220, the third terminal 230, the fourth terminal 240, the first wire harness 310, the second wire harness 320, the third wire harness 330, and the fourth wire harness 340 may differ in different embodiments. For example, Figure 5 - Figure 9 The illustrated embodiments and Figure 10 - Figure 13In the illustrated embodiments, although the structure and relative positions of each component are the same, the relative positions of each terminal and each wire harness differ due to different naming conventions. Therefore, they are considered to be different embodiments. For ease of description, unless otherwise specified, they will be referred to as [specific embodiments]. Figure 5 - Figure 9 The illustrated embodiment will be used as an example for explanation.

[0084] In this embodiment, the high-voltage wire harness (first harness 310) and low-voltage wire harness (second harness 320) of the electrical control box assembly 10 are respectively led out of the first housing 100 through different openings (i.e., first opening 111 and second opening 123). Compared with the related art where the high-voltage and low-voltage wire harnesses are combined and led out through the same opening of the first housing, in this embodiment, the high-voltage and low-voltage wire harnesses are set separately, reducing their electromagnetic interference. Furthermore, in this embodiment, the first opening 111 is located on the first side plate 110 of the first housing 100, and the second opening 123 is located on the second side plate 120 of the first housing 100. The first side plate 110 and the second side plate 120 are located on different sides of the first housing 100. Compared with the related art where the high-voltage and low-voltage wire harnesses are led out through two openings on the same side plate of the housing, in this embodiment, the difference in the spacing and leading direction between the high-voltage and low-voltage wire harnesses is greater, thereby reducing their electromagnetic interference.

[0085] See Figure 5 - Figure 9 In some embodiments, when the first side plate 110 and the second side plate 120 are located on adjacent sides of the first housing 100, interference between the high-voltage and low-voltage wire harnesses can be reduced while allowing the high-voltage and low-voltage wire harnesses leading out of the first housing 100 to be installed and fixed simultaneously. In other embodiments, the first side plate 110 and the second side plate 120 can also be located on opposite sides of the first housing 100. In this configuration, since the distance between the first opening 111 and the second opening 123 is relatively greater, the routing positions of the first wire harness 310 and the second wire harness 320 are further apart, resulting in less electromagnetic interference between the high-voltage and low-voltage wire harnesses.

[0086] See Figure 5 - Figure 9In some embodiments, the electrical control box assembly 10 further includes a fixing bracket 400 connected to the outside of the first housing 100. The fixing bracket 400 can be connected to any side plate of the first housing 100, that is, the fixing bracket 400 can be connected to the first side plate 110 and / or the second side plate 120, or it can be connected to other side plates of the first housing 100 besides the first side plate 110 and the second side plate 120. In this embodiment, the fixing bracket 400 is connected to the first side plate 110. The fixing bracket 400 includes a first fixing structure 430 and a second fixing structure 440, the first fixing structure 430 being adapted to fix the first wiring harness 310, and the second fixing structure 440 being adapted to fix the second wiring harness 320. In this design, on the one hand, a fixing bracket 400 is connected to the outside of the first housing 100, so that when the electrical control box assembly 10 is assembled separately, the various wire harnesses leading out of the first housing 100 of the electrical control box assembly 10 can be pre-fixed. Compared with the structure where the fixing bracket 400 is separated from the first housing 100 and connected to the chassis 22 of the indoor unit 1, this design facilitates the pre-assembly of the electrical control box assembly 10. On the other hand, the fixing bracket 400 fixes both the first wire harness 310 and the second wire harness 320. Compared with the structure where the fixing bracket 400 only fixes the first wire harness 310 or only fixes the second wire harness 320, the structure of this design is more compact and the wire harnesses are more organized.

[0087] The specific fixing method of the first fixing structure 430 depends on actual needs. The first fixing structure 430 can detachably fix the first wire harness 310 or it can fix the first wire harness 310 non-detachably. In this embodiment, the first fixing structure 430 detachably fixes the first wire harness 310. Specifically, see [link to documentation]. Figure 5 The first fixing structure 430 includes multiple spaced-apart supporting arms 450. A locking space is formed on one side of each supporting arm 450. The first wire harness 310 passes through the locking space of each supporting arm 450, thereby being limited by the supporting arm 450 to guide the first wire harness 310 while ensuring its neatness. Furthermore, adjacent supporting arms 450 are staggered, meaning the fixed and free ends of adjacent supporting arms 450 are in opposite positions. This allows the first wire harness 310 to be easily attached and detached from the first fixing structure 430 while achieving good limiting of the first wire harness 310. The specific fixing method of the second fixing structure 440 can be similar to that of the first fixing structure 430, and will not be described in detail here.

[0088] See Figure 5 - Figure 9In some embodiments, the first side plate 110 and the second side plate 120 are located on adjacent sides of the first housing 100. Furthermore, a fixing bracket 400 is connected to the end of the first side plate 110 near the second side plate 120. In this embodiment, on one hand, the fixing bracket 400 is connected to the first side plate 110, so that the first fixing structure 430 on the fixing bracket 400 is closer to the first side plate 110, making it easier for the first fixing structure 430 to fix the first wire harness 310 extending from the first opening 111 of the first side plate 110; on the other hand, the fixing bracket 400 is positioned closer to the second side plate 120, so that the second fixing structure 440 on the fixing bracket 400 is closer to the second side plate 120, making it easier for the second fixing structure 440 to fix the second wire harness 320 extending from the second opening 123 of the second side plate 120. In other embodiments, the fixing bracket 400 may also be connected to the end of the second side plate 120 near the first side plate 110, or the fixing bracket 400 may be connected to both the end of the first side plate 110 near the second side plate 120 and the end of the second side plate 120 near the first side plate 110.

[0089] To further facilitate the guidance and fixing of the first wire harness 310 and the second wire harness 320, see the following: Figure 6 - Figure 8 In some embodiments, the first opening 111 is located on the side of the first side plate 110 near the second side plate 120, and the second opening 123 is located on the side of the second side plate 120 near the first side plate 110. In this configuration, the first wire harness 310 leading to the first opening 111 is closer to the fixing bracket 400, and the second wire harness 320 leading to the second opening 123 is closer to the fixing bracket 400. In a further embodiment, along the first direction X, the first opening 111 at least partially coincides with the position of the fixing bracket 400, thereby ensuring that the first wire harness 310 leading to the first opening 111 does not require excessive bending during the fixation of the first fixing structure 430.

[0090] When the fixing bracket 400 is connected to both the first wiring harness 310 and the second wiring harness 320, see Figure 6 - Figure 8In some embodiments, the fixing bracket 400 has a first region 410 and a second region 420 located on different sides. The first region 410 is connected to a first opening 111, and the second region 420 is connected to a second opening 123. A first fixing structure 430 is located in the first region 410, and a second fixing structure 440 is located in the second region 420. In this configuration, the first wire harness 310 extending from the first opening 111 is fixed by the first fixing structure 430 located in the first region 410, and the second wire harness 320 extending from the second opening 123 is fixed by the second fixing structure 440 located in the second region 420. Since the first region 410 and the second region 420 are located on different sides of the fixing bracket 400, the positional distance between the first wire harness 310 and the second wire harness 320 is relatively large, resulting in less electromagnetic interference between them.

[0091] See Figure 6 - Figure 8 In some embodiments, the first housing 100 has a first direction X and a second direction Y that intersect each other. A first side plate 110 is located on one side of the first housing 100 along the first direction X, and a second side plate 120 is located on one side of the first housing 100 along the second direction Y. One side of the first side plate 110 is connected to the second side plate 120. The directions intersecting the first direction X and the second direction Y are respectively a third direction Z (which can be the thickness direction of the first housing 100). A first region 410 is located on one side of the fixing bracket 400 along the third direction Z, and a second region 420 is located on one side of the fixing bracket 400 along the second direction Y. For example, with Figure 8 The orientation shown is for reference. The first side plate 110 is the lower side plate of the first housing 100, and the second side plate 120 is the left side plate of the first housing 100. The first opening 111 is located on the left side of the first side plate 110, and the second opening 123 is located on the lower side of the second side plate 120. The fixing bracket 400 is connected to the left side of the first side plate 110, and the first region 410 is located on the front side of the fixing bracket 400, and the second region 420 is located on the left side of the fixing bracket 400. This design allows the first wire harness 310, which extends from the first opening 111, to extend directly downward (i.e., along the first direction X) to the first region 410 and be fixed to the first fixing structure 430, and the second wire harness 320, which extends from the second opening 123, to the left (i.e., along the second direction Y) to the second region 420 and be fixed to the second fixing structure 440. The above-described structural arrangement of the fixing bracket 400 and the first housing 100 makes it easier to assemble and fix the first wire harness 310 and the second wire harness 320.

[0092] See Figure 7 - Figure 8In some embodiments, the control box assembly 10 further includes a second housing 500 and a display assembly 700. The second housing 500 defines a second receiving cavity and has a viewing window 510 communicating with the second receiving cavity. The display assembly 700 is disposed in the second receiving cavity and can specifically display at least one of information such as temperature, humidity, operating mode, and time. The display assembly 700 displays information outward from the second receiving cavity through the viewing window 510, meaning the user can obtain the information displayed by the display assembly 700 within the second receiving cavity through the viewing window 510. The second housing 500 is connected to the end of the fixing bracket 400 opposite to the first housing 100, and a second wiring harness 320 passes through the second housing 500 and is electrically connected to the display assembly 700 located within the second housing 500. In this design, the display component 700 is integrated with the first housing 100. This reduces the number of parts and allows the display component 700 and the second wiring harness 320 to be pre-assembled and connected before the indoor unit 1 is fully assembled, eliminating the need to connect the second wiring harness 320 and the display component 700 during final assembly. This provides more operating space and makes assembly of the second wiring harness 320 and the display component 700 more convenient. Furthermore, in this design, the second housing 500 is connected to the side of the fixed bracket 400 away from the first housing 100, keeping the second housing 500 relatively far from the first housing 100 and reducing electromagnetic interference to the display component 700 from the high-voltage wiring harness inside the first housing 100.

[0093] When the second housing 500 is connected to the fixing bracket 400, the second housing 500 can also serve to fix the wire assembly 300, thereby improving the neatness of the wire harness. For details, see... Figure 6 - Figure 8 In some embodiments, a third fixing structure 520 is provided on the outer side of the second housing 500. The third fixing structure 520 fixes the first wire harness 310 and / or the second wire harness 320. The specific fixing method of the third fixing structure 520 can be referred to the first fixing structure 430 mentioned above. In this solution, the first wire harness 310 or the second wire harness 320 is fixed by the third fixing structure 520 on the third housing, so that the third housing performs part of the function of the fixing bracket 400, thus reducing the volume of the fixing bracket 400.

[0094] The second wiring harness 320 may include a single wire that is electrically connected to the display assembly 700. The second wiring harness 320 may also include multiple wires, each connected to a different low-voltage component. See also... Figure 6 - Figure 8In some embodiments, the second wiring harness 320 includes a first wire 321 and a second wire 322. The first wire 321 is adapted to electrically connect to a sensor or a wireless communication component; and / or, the second wire 322 is adapted to electrically connect to a display component 700. The sensor may specifically be a temperature sensor, a humidity sensor, or a refrigerant sensor, etc. The wireless communication component may be a WIFI module. In this design, the second wire 322 includes multiple wires, each connecting to a different low-voltage component, thus enriching the control elements of the control box. Further, the first wire 321 and the second wire 322 extend from the second opening 123 outwards in two intersecting directions. Specifically, the first wire 321 extends downwards to connect to the display component 700, and the second wire 322 extends backwards to connect to the sensor or the wireless communication component. In this design, the first wire 321 and the second wire 322 extend in different directions after exiting the second opening 123, thereby further preventing electromagnetic interference between different wires and facilitating wire organization, making it less prone to tangling or knotting.

[0095] See Figure 7 - Figure 9 In some embodiments, the circuit board 200 is provided with a third terminal 230, which is a high-voltage terminal. The first housing 100 is also provided with a third opening 112 communicating with the first receiving cavity 150. The wire assembly 300 also includes a third wire harness 330, which is electrically connected to the third terminal 230 and passes through the third opening 112. In this scheme, one of the first wire harness 310 and the third wire harness 330 can be a power line to allow the user to obtain electrical energy; the other of the first wire harness 310 and the third wire harness 330 can be an output wire to allow the user to output electrical energy. Specifically, the output wire can be electrically connected to components such as a drive motor or a compressor. To facilitate the common lead-out of the high-voltage wire harness, in some embodiments, the third opening 112 and the first opening 111 are both provided on the same side plate. In this embodiment, the third opening 112 can be provided on the first side plate 110. To facilitate the operator's differentiation between the first terminal 210 and the third terminal 230 during assembly and to prevent electromagnetic interference between them, and to facilitate the matching of the relative positions of the first terminal 210 and the third terminal 230, in some embodiments, the third opening 112 and the first opening 111 may be located on opposite sides of the first side plate 110.

[0096] See Figure 7 - Figure 9In some embodiments, the circuit board 200 is provided with a fourth terminal 240, which is a low-voltage terminal. The first housing 100 also includes a third side plate 130, which is located on different sides of the first side plate 110. The third side plate 130 is provided with a fourth opening 131 communicating with the first receiving cavity 150. The wire assembly 300 also includes a fourth wire harness 340, which is electrically connected to the fourth terminal 240 and passes through the fourth opening 131. In this solution, the addition of an extra low-voltage wire harness makes the control elements of the electrical control box assembly 10 more diverse. Specifically, the fourth wire harness 340 can control components such as a stepper motor for driving the air guide plate and / or an air purification module for purifying air.

[0097] like Figure 5 - Figure 9 In the illustrated embodiment, the first side plate 110 is located on the lower side, and the second side plate 120 is located on the left side. In other embodiments, the first side plate 110 and the second side plate 120 may have other relative positional relationships. See also Figure 10 - Figure 13 The following description uses this embodiment as an example. Figure 10 - Figure 13 The orientation shown is for reference only. The first side plate 110 is located on the lower side, and the second side plate 120 is located on the front side. Furthermore, the second side plate 120 has a recess 1211 on the side opposite to the first receiving cavity 150. The recess 1211 forms a protruding structure inside the first receiving cavity 150 and a groove structure outside the first receiving cavity 150. Along the thickness direction of the second side plate 120, the first wire harness 310 at least partially coincides with the position of the recess 1211. In other words, along the thickness direction of the second side plate 120 (i.e.,...) Figure 10 As shown in the third-party view (Z), at least a portion of the first wire harness 310 coincides with the recess 1211. At least a portion of the second wire harness 320, which passes outside the second opening 123, is located inside the recess 1211. This arrangement results in the first wire harness 310 extending from the side of the recess 1211 facing the first receiving cavity 150, and the second wire harness 320 extending from the side of the recess 1211 away from the first receiving cavity 150. The two are separated by the second side plate 120. Compared to a structure where both the first wire harness 310 and the second wire harness 320 extend within the first receiving cavity 150, the electromagnetic interference between the first wire harness 310 and the second wire harness 320 is less. Meanwhile, because a recess 1211 is provided on the second side plate 120, the second wiring harness 320 will not occupy too much space outside the first housing 100, thus reducing the overall volume of the electrical control box. Furthermore, the recess 1211 also defines a limiting channel for the second wiring harness 320, allowing assembly personnel to assemble the second wiring harness 320 according to the limiting channel defined by the recess 1211, thereby improving assembly efficiency.

[0098] The specific structure of the recess 1211 is determined according to actual needs. Figure 10 - Figure 13 In this embodiment, the recess 1211 is a roughly rectangular groove, and the forming of the recess 1211 is relatively simple. In other embodiments, the recess 1211 can be strip-shaped, and the recess 1211 extends according to the direction of the second wire harness 320, thereby providing better guidance and limiting effect for the second wire harness 320.

[0099] To further improve the limiting effect on the second wiring harness 320, Figure 10 - Figure 13 In some embodiments, the second side plate 120 is provided with a fourth fixing structure 124 located outside the first receiving cavity 150. The fourth fixing structure 124 is connected to the second wire harness 320. The recess 1211 is at least partially located between the fourth fixing structure 124 and the second opening 123. The second wire harness 320 extends out of the first housing 100 through the second opening 123, passes through the recess 1211, and is connected and fixed by the fourth fixing structure 124. In this solution, the addition of the fourth fixing structure 124, and the fact that the fourth fixing structure 124 is connected to the second side plate 120, improves the positioning effect of the second wire harness 320. The specific fixing method of the fourth fixing structure 124 is described above for the first fixing structure 430, and will not be repeated here.

[0100] Figure 10 - Figure 13 In some embodiments, the first housing 100 includes a concave shell 140 and a second side plate 120. The concave shell 140 includes a first side plate 110 and may also include a third side plate 130. The second side plate 120 includes a first plate 121 and a second plate 122, which are separately disposed and detachably connected to the concave shell 140. The first plate 121, the second plate 122, and the concave shell 140 together form a first receiving cavity 150. In this design, the second side plate 120 is configured as two plates detachably connected to the concave shell 140, so that only one plate can be opened during maintenance without disassembling the entire second side plate 120, making maintenance operations more convenient.

[0101] In some embodiments, the first plate 121 is provided with a recess 1211, and the gap between the first plate 121 and the second plate 122 together forms a second opening 123, with the recess 1211 communicating with the second opening 123. In this solution, the second opening 123 is formed through the gap between the first plate 121 and the second plate 122, without the need for an additional opening, making processing simpler. Furthermore, the second opening 123 is formed between one end of the recess 1211 and the second plate 122, that is, the groove structure of the recess 1211 is reasonably utilized to form the second opening 123. On the one hand, the forming of the second opening 123 is simpler; on the other hand, after the second wire harness 320 is led out from the second opening 123, it is immediately limited and guided by the recess 1211, resulting in better positioning of the second wire harness 320.

[0102] Figure 10 - Figure 13 In some embodiments, the electrical control box assembly 10 further includes a fixing bracket 400 connected to the outside of the first housing 100. The fixing bracket 400 includes a first fixing structure 430, on one side of which a first wiring harness 310 is fixed, and on the side of the first fixing structure 430 opposite to the first wiring harness 310, a second wiring harness 320 is fixed. The first wiring harness 310 and the second wiring harness 320 are arranged crosswise at the first fixing structure 430. In this design, the first wiring harness 310 and the second wiring harness 320 are located on opposite sides of the first fixing structure 430. On the one hand, the first fixing structure 430 can simultaneously limit the positions of the first wiring harness 310 and the second wiring harness 320, resulting in a simpler structure. On the other hand, the first fixing structure 430 can separate the first wiring harness 310 and the second wiring harness 320, effectively reducing electromagnetic interference between them.

[0103] Figure 10 - Figure 13 In some embodiments, the circuit board 200 is provided with a third terminal 230, which is a high-voltage terminal. The first side plate 110 is also provided with a third opening 112 communicating with the first receiving cavity 150. The wire assembly 300 also includes a third wire harness 330, which is electrically connected to the third terminal 230 and passes through the third opening 112. The circuit board 200 is provided with a fourth terminal 240, which is a low-voltage terminal. The first housing 100 also includes a third side plate 130, which is located on different sides of the first housing 100 from the first side plate 110. The third side plate 130 is provided with a fourth opening 131 communicating with the first receiving cavity 150. The wire assembly 300 also includes a fourth wire harness 340, which is electrically connected to the fourth terminal 240 and passes through the fourth opening 131.

[0104] Figure 5 - Figure 13In some embodiments, the electrical control box assembly 10 further includes an electrical connector 600, one end of which is adapted to electrically connect to the circuit board 200, and the other end is adapted to electrically connect to the outdoor unit. The electrical connector 600 is connected to the first housing 100 and abuts against the second wiring harness 320. That is, the electrical connector 600 can limit the positioning of the second wiring harness 320, thereby further improving the positioning effect of the second wiring harness 320.

[0105] See Figure 1 - Figure 13 The second aspect of this utility model also provides an indoor unit 1, which includes the electrical control box assembly 10 of any of the above-mentioned components. The indoor unit 1 may also include a housing 20, a heat exchange assembly 30, and electrical components. When the indoor unit 1 is a wall-mounted unit, the housing 20 may include a front frame 21, a chassis 22, and a front panel 23. The electrical control box assembly 10 may be connected to one end of the chassis 22, and the heat exchange assembly 30 may be connected to the chassis 22. The heat exchange assembly 30, the chassis 22, and the electrical control box assembly 10 are all disposed within the front frame 21, and the front panel 23 is disposed on the front side of the front frame 21. The heat exchange assembly 30 is used to exchange heat with the air, thereby regulating the air temperature. The electrical components of the indoor unit 1 are electrically connected to the electrical control box assembly 10 to perform corresponding functions under the control of the electrical control box assembly 10. The electrical components may specifically include the sensors mentioned above, wireless communication modules, drive motors for driving air guide plates, air purification modules for air purification, compressors, or drive motors for driving air supply components, etc. Given the improvements to the electrical control box assembly 10, the indoor unit 1 in this application has all the technical effects of the aforementioned electrical control box assembly 10.

[0106] A third aspect of this utility model also provides an air conditioner, which includes an indoor unit 1 and an outdoor unit as described in any of the above embodiments, with the outdoor unit connected to the indoor unit 1. The electrical components of the indoor unit 1 are electrically connected to the electrical connector 600 of the electrical control box assembly 10, thereby being electrically connected to the circuit board 200. Given the improvements to the electrical control box assembly 10, the air conditioner of this application possesses all the technical effects of the aforementioned electrical control box assembly 10.

[0107] It should be noted that if any directional indication (such as up, down, left, right, front, back, etc.) is involved in the embodiments of this utility model, such directional indication is only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indication will also change accordingly. When a directional reference is introduced in a specific embodiment, unless the direction is specifically limited to unidirectional, the direction can be unidirectional or bidirectional (two parallel and opposite directions). Whether it is unidirectional or bidirectional depends on what those skilled in the art can achieve. When the directional reference is bidirectional, it should be considered that two parallel and different embodiments have been introduced simultaneously.

[0108] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0109] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
