Description

Technical Field

[0001] This application relates to the field of air conditioner technology, and in particular to an electrical control box and an air conditioner. Background Technology

[0002] The electrical control box is one of the core components of an air conditioner, undertaking the crucial task of controlling the power distribution and logical operation of the entire system. The design and manufacturing quality of the electrical control box directly affects the performance and reliability of the air conditioner. In related technologies, the wiring harness on the circuit board bracket inside the electrical control box needs to pass through the box to connect to external power sources or components. To ensure the smooth passage of the motor wires, the electrical control box is usually designed with a U-shaped opening. However, at the U-shaped opening, the sheet metal parts of the electrical control box are in direct contact with the motor wires, posing a risk of scratching or tearing the wires. Usually, an additional U-shaped rubber pad is needed for protection, but this measure not only increases material costs but also complicates the assembly process and reduces assembly efficiency. Furthermore, there is a risk that external water droplets can easily flow into the electrical control box along the wiring harness, causing a short circuit. To solve this problem, the current common method is to weld iron-plastic strips onto the electrical control box to secure the motor wires. However, this measure increases the number of processes, welding costs, and material costs, further exacerbating the reduction in production efficiency and the increase in manufacturing costs. Utility Model Content

[0003] This application aims to at least solve one of the technical problems existing in the prior art. To this end, one objective of this application is to provide an electrical control box that, through a water-blocking component, can achieve good fixation and protection of the connecting wire harness while optimizing the waterproof performance of the electrical control box. This eliminates the need for additional U-shaped rubber pads and iron-plastic strips, thereby improving production efficiency and saving manufacturing costs.

[0004] This application also proposes an air conditioner having the aforementioned electrical control box.

[0005] According to an embodiment of the first aspect of this application, the electrical control box includes: a box body, a circuit board bracket, and a water-blocking member. The box body defines an accommodating space, and a first cable outlet hole is provided on the periphery of the box body. The circuit board bracket is used to fix a circuit board and is disposed within the accommodating space. The water-blocking member is connected to the box body and / or the circuit board bracket. The connecting wire harness on the circuit board is adapted to pass through the first cable outlet hole, and the water-blocking member has a first side plate located above the first cable outlet hole and a second side plate opposite to the first cable outlet hole. The first side plate and the second side plate have an angle and are adapted to guide the connecting wire harness to bend relative to the first side plate and the second side plate to form a wire harness return structure.

[0006] According to the electrical control box of this application, by setting a water-blocking component, a water-return bend structure is formed at the point where the connecting wire harness exits the box body. This prevents water droplets from flowing into the box body along the connecting wire harness through the first outlet hole, effectively improving the waterproof performance of the electrical control box, ensuring the safe operation of the circuit board and connecting wire harness inside the box, and improving the reliability and safety of the electrical control box. Simultaneously, the water-blocking component also provides good fixation and protection for the connecting wire harness. The bending path and angle defined by the water-blocking component ensure good installation stability of the connecting wire harness at the point where it passes through the first outlet hole, and protects the connecting wire harness from excessive bending or wear during its exit from the box body, thereby improving the installation stability and lifespan of the connecting wire harness. Compared with related technologies, additional U-shaped rubber pads and iron-plastic strips are required to fix and protect the connecting wire harness, resulting in more processes, lower production efficiency, and increased manufacturing costs. This application uses a water-blocking component, which can achieve good fixation, protection and waterproofing of the connecting wire harness, while avoiding the use of U-shaped rubber pads and iron-plastic strips. This can reduce production and assembly processes, improve production efficiency, and save on material costs and welding costs associated with using U-shaped rubber pads and iron-plastic strips.

[0007] According to some embodiments of this application, the water-blocking component further includes: a base plate, a first side plate connected to the upper edge of the base plate, a second side plate connected to the lateral edge of the base plate, and the base plate, the first side plate, and the box body or the circuit board bracket.

[0008] In some embodiments, the bottom projection outline of the second side plate is located below the lower edge of the first cable outlet when projected toward the housing.

[0009] Furthermore, the circuit board bracket is provided with a second cable outlet corresponding to the first cable outlet. After the box body is assembled with the circuit board bracket, the first cable outlet and the second cable outlet overlap or are arranged opposite to each other. A first wire harness buckle is provided on the second cable outlet. The first wire harness buckle is opposite to the second side plate and is used to limit the connection wire harness.

[0010] According to some embodiments of this application, the circuit board bracket is further provided with a plurality of second wire harness clips, which are spaced apart in the circuit board bracket and are used to limit the connection wire harness.

[0011] Furthermore, the second wire harness clip includes: a first upright plate and a second upright plate, wherein the first upright plate and the second upright plate of the same second wire harness clip are disposed opposite to each other to define a wire passage space, and the outer surface corner areas of the first upright plate and the second upright plate opposite to the wire passage space are rounded.

[0012] Furthermore, the second wire harness clip also includes a limiting plate, which is disposed at the free end of the first upright plate and / or the second upright plate, and the limiting plate extends toward the wire passage space.

[0013] According to some embodiments of this application, the electrical control box further includes: a mounting frame connected to the box body, the mounting frame having a third wiring harness buckle disposed opposite to the second side plate, the third wiring harness buckle being adapted to guide the connecting wiring harness to bend and extending along the extension direction of the second side plate to the end of the mounting frame.

[0014] Furthermore, a fourth wire harness buckle is provided at the end of the mounting frame. The fourth wire harness buckle is used to limit the protruding end of the connecting wire harness. The fourth wire harness buckle is provided on two corner areas at the same end of the mounting frame so that multiple connecting wire harnesses can be led out from the same end of the mounting frame.

[0053] The following is for reference. Figures 1-16 This application describes an electrical control box 100 and an air conditioner 10000 according to embodiments thereof.

[0054] like Figure 3 As shown, according to the first aspect embodiment of the present application, the electrical control box 100 includes: a box body 110, a circuit board bracket 120, and a water-blocking member 130.

[0055] The box body 110 defines an accommodating space 110a, and a first cable outlet hole 110b is provided on the periphery of the box body 110; a circuit board support 120 is used to fix the circuit board, and the circuit board support 120 is disposed in the accommodating space 110a; a water-blocking member 130 is connected to the box body 110 and / or the circuit board support 120; a connecting wire harness 140 on the circuit board is adapted to pass through the first cable outlet hole 110b, and the water-blocking member 130 has a first side plate 132 located above the first cable outlet hole 110b and a second side plate 134 opposite to the first cable outlet hole 110b. The first side plate 132 and the second side plate 134 have an angle and are adapted to guide the connecting wire harness 140 to bend relative to the first side plate 132 and the second side plate 134 to form a wire harness return structure.

[0056] Specifically, the housing 110 may have an accommodating space 110a, which can be used to install, fix, and protect some other components of the electrical control box 100 (such as the circuit board bracket 120). One or more through-holes 110b are provided around the periphery of the housing 110. The through-holes 110b allow the connecting wires 140 on the circuit board inside the housing 110 to pass through the housing 110, so that the connecting wires 140 can be connected to an external power source or component to enable normal electrical control operation of the electrical control box 100. The circuit board bracket 120 is disposed within the accommodating space 110. Inside a, it is used to stably support and fix the circuit board so that the circuit board is safely placed in the electrical control box 100 without being interfered with or damaged by external factors; each first outlet hole 110b is correspondingly provided with a water baffle 130. The water baffle 130 can be arranged in three ways: first, the water baffle 130 can be connected only to the box body 110 and not to the circuit board support 120; second, the water baffle 130 can also be connected only to the circuit board support 120 and not to the box body 110; third, the water baffle 130 can also be connected to both the box body 110 and the circuit board support 120. The water-blocking component 130 has a first side plate 132 and a second side plate 134. The first side plate 132 is located above the first cable outlet hole 110b. It can be understood that the projection of the first side plate 132 in the height direction of the housing 110 is higher than the projection of the first cable outlet hole 110b in the height direction of the housing 110. The second side plate 134 and the first cable outlet hole 110b can be arranged opposite to each other on the periphery of the housing 110. The first side plate 132 and the second side plate 134 are connected and their extension directions intersect. There is an included angle between the first side plate 132 and the second side plate 134. The included angle can be an acute angle, a right angle or an obtuse angle, so as to provide a specific bending path for connecting the wire harness 140.

[0057] Understandably, when the connecting wire harness 140 on the circuit board passes through the first exit hole 110b inside the housing 110, the connecting wire harness 140 first contacts the first side plate 132 and extends along the first side plate 132. After the connecting wire harness 140 extends to the position between the first side plate 132 and the second side plate 134, since there is an angle between the first side plate 132 and the second side plate 134, the connecting wire harness 140 bends at this point to extend along the second side plate 134 and finally exits from the side of the second side plate 134 away from the first side plate 132. The water-blocking component 130 is formed as a natural water-return bend structure. Under the limiting action of the water-blocking component 130, the connecting wire harness 140 passing through the first wire outlet hole 110b is formed as a wire harness water-return bend structure. In this way, when water droplets or other liquids come into contact with the connecting wire harness 140, the water-return bend structure will block the liquid flowing along the connecting wire harness 140 outside the water-blocking component 130, thereby preventing water droplets or other liquids from flowing into the box 110 from the outside along the connecting wire harness 140.

[0058] According to the electrical control box 100 of this application, by setting a water-blocking component 130, the connecting wire harness 140 forms a wire harness water return bend structure at the point where it exits the box body 110. This prevents water droplets from flowing into the box body 110 along the connecting wire harness 140 through the first outlet hole 110b, effectively improving the waterproof performance of the electrical control box 100, ensuring the safe operation of components such as the circuit board and connecting wire harness 140 inside the electrical control box 100, and improving the reliability and safety of the electrical control box 100. At the same time, the water-blocking component 130 also provides good fixation and protection for the connecting wire harness 140. The bending path and angle defined by the water-blocking component 130 ensure good installation stability of the connecting wire harness 140 at the point where it passes through the first outlet hole 110b, and protects the connecting wire harness 140 from excessive bending or wear during its exit from the box body 110, thereby improving the installation stability and lifespan of the connecting wire harness 140. Compared with related technologies, additional U-shaped rubber pads and iron-plastic strips are required to fix and protect the connecting wire harness 140, resulting in more processes, lower production efficiency, and increased manufacturing costs. In this application, a water-blocking component 130 is used, which can achieve good fixation, protection and waterproofing of the connecting wire harness 140, while avoiding the use of U-shaped rubber pads and iron-plastic strips. This can reduce production and assembly processes, improve production efficiency, and save on material costs and welding costs associated with using U-shaped rubber pads and iron-plastic strips.

[0059] like Figure 9 As shown, according to some embodiments of this application, the water-blocking component 130 further includes: a base plate 136, a first side plate 132 connected to the upper edge of the base plate 136, a second side plate 134 connected to the lateral edge of the base plate 136, and the base plate 136, the first side plate 132 connected to the box body 110 or the circuit board bracket 120.

[0060] Specifically, the base plate 136 can serve as a base to provide a stable support surface for the connecting wire harness 140 and ensure the installation and fixation of the first side plate 132 and the second side plate 134. One long edge of the first side plate 132 can be connected to the upper edge of the bottom plate 136 in the height direction of the box 110, and one long edge of the second side plate 134 can be connected to at least a portion of the lateral edge of the bottom plate 136. Thus, the surfaces of the bottom plate 136, the first side plate 132, and the second side plate 134 facing each other together define a cavity that is open away from the first side plate 132 in the height direction. The cavity houses at least a portion of the connecting wire harness 140, defining at least a portion of the connecting wire harness 140 as a wire harness water trap structure to block water droplets, and defining a portion of the connecting wire harness 140 extending downward away from the first side plate 132 to extend out of the cavity. The first side plate 132 is located above the connecting wire harness 140, forming a vertical or inclined barrier surface of the water-blocking member 130, which can block water droplets or liquids from above the connecting wire harness 140 and also serve a waterproof function.

[0061] Furthermore, in some specific embodiments of this application, the base plate 136, the first side plate 132, and the second side plate 134 can be integrally formed with the box body 110, or the base plate 136, the first side plate 132, and the second side plate 134 can be integrally formed with the circuit board support 120 to ensure the stability and reliability of the water-blocking component 130, thereby enhancing the waterproof performance of the electrical control box 100 and protecting the circuit board and other electronic components as well as the safe operation of the connecting wire harness 140.

[0062] like Figure 3 , Figure 5 as well as Figure 9 As shown, according to some embodiments of this application, the bottom projection outline of the second side plate 134 is located below the lower edge of the first cable outlet hole 110b when projected toward the housing 110.

[0063] Specifically, when projected onto the box 110, the bottom projection outline of the second side plate 134 is located below the lower edge of the first wire outlet hole 110b, so that the bottom of the second side plate 134 can completely cover the bottommost area of ​​the first wire outlet hole 110b. The connecting wire harness 140 extends along the second side plate 134 at the position of the water-blocking member 130, and is located below the bottommost area of ​​the first wire outlet hole 110b. In this way, the waterproof range of the water-blocking member 130 to the first wiring hole can be fully guaranteed, and the water-blocking function of the connecting wire harness 140 can be effectively achieved. This can effectively prevent water droplets from entering the box 110 along the connecting wire harness 140 that passes through the first wire outlet hole 110b, thereby ensuring the safe operation of the electrical control box 100 and its internal circuits.

[0064] Furthermore, in some specific embodiments of this application, such as Figure 16As shown, the base plate 136 includes a first plate segment 1361 and a second plate segment 1362 arranged sequentially in the direction away from the circuit board support 120 on the second side plate 134. The sides of the first plate segment 1361 and the second plate segment 1362 away from each other are respectively connected to the circuit board support and the second side plate 134. The same end of the first plate segment 1361 and the second plate segment 1362 in the extension direction of the second side plate 134 is connected to the first side plate 132 and projected toward the box body 110. The projection outline of the other end of the second plate segment 1362 is located below the projection outline of the other end of the first plate segment 1361, so as to ensure that the connecting wire harness 140 forms a good wire harness return water bend structure in the water-blocking member 130, so as to ensure a good water-blocking effect.

[0065] Furthermore, in some other specific embodiments of this application, the other end of the second plate segment 1362 has an arc-shaped portion 1362a, and the width of the other end of the second plate segment 1362 gradually decreases in the direction away from the first plate segment 1361. In this way, the transition between the other end of the second plate segment 1362 and the other end of the first plate segment 1361 is smooth, which can protect the connecting wire harness 140 from being scratched.

[0066] like Figure 3 and Figure 13 As shown, according to some embodiments of this application, the circuit board bracket 120 is provided with a second cable outlet 120a corresponding to the first cable outlet 110b. After the housing 110 and the circuit board bracket 120 are assembled, the first cable outlet 110b and the second cable outlet 120a are overlapped or opposite to each other. A first wire harness buckle 122 is provided on the second cable outlet 120a. The first wire harness buckle 122 is opposite to the second side plate 134 and is used to limit the connection wire harness 140.

[0067] Specifically, the circuit board bracket 120 is provided with a second cable outlet 120a corresponding to the first cable outlet 110b on the housing 110. When the housing 110 and the circuit board bracket 120 are assembled together, the first cable outlet 110b and the second cable outlet 120a are in an overlapping or relative positional relationship to ensure that the connecting wire harness 140 can pass through the circuit board bracket 120 and the housing 110 in sequence and smoothly exit from the inside of the housing 110, and provide a clear exit path for the connecting wire harness 140. This helps to improve the assembly and maintenance convenience and efficiency of the connecting wire harness 140, the circuit board bracket 120 and the housing 110. A first wire harness clip 122 is provided on the second outlet hole 120a. The first wire harness clip 122 can be spaced apart from and opposite to the second side plate 134. The first wire harness clip 122 can surround the connecting wire harness 140 to limit the connecting wire harness 140, which can prevent the connecting wire harness 140 from loosening or being damaged due to vibration or external force. In this way, the installation stability of the connecting wire harness 140 can be effectively improved, making the connection and fixation of the connecting wire harness 140 inside and outside the box 110 more reliable and stable. It also helps to protect the connecting wire harness 140 from damage by other components, and can improve the stability and reliability of the connecting wire harness 140 when transmitting signals or power.

[0068] like Figure 7 , Figure 11 , Figure 13 as well as Figure 15 As shown, according to some embodiments of this application, a plurality of second wire harness clips 124 are also provided in the circuit board bracket 120. The second wire harness clips 124 are spaced apart in the circuit board bracket 120 and are used to limit the connection wire harness 140.

[0069] Specifically, the circuit board bracket 120 may be provided with a plurality of second wire harness clips 124. These clips can be spaced at different locations within the circuit board bracket 120 according to the different wiring requirements of the connecting wire harnesses 140, to limit and fix the connecting wire harnesses 140 accordingly. For example, when the connecting wire harnesses 140 extend along the height direction on the circuit board bracket 120, a plurality of second wire harness clips 124 spaced apart along the height direction can be provided within the circuit board bracket 120 to maintain the connecting wire harnesses 140 extending along the height direction and ensure the stable installation of the connecting wire harnesses 140 on the circuit board bracket 120. Similarly, the second wire harness clips 124 can be arranged around the connecting wire harness 140 to limit its movement, preventing it from loosening or being damaged due to vibration or external force. This effectively improves the stability of the connecting wire harness 140 installation, making its connection and fixation within and outside the circuit board bracket 120 more reliable and stable. It also helps protect the connecting wire harness 140 from damage by other components, improving its stability and reliability when transmitting signals or power. Furthermore, the multiple second wire harness clips 124 limit the movement of the connecting wire harness 140 on the circuit board bracket 120, ensuring orderly and standardized guidance and improving the efficiency and neatness of wire harness management.

[0070] Furthermore, in some specific embodiments of this application, both the second wire harness clip 124 and the first wire harness clip 122 are made of elastic material, possessing a certain degree of elasticity and resilience. When the connecting wire harness 140 is placed in the second wire harness clip 124 and the first wire harness clip 122, the second wire harness clip 124 and the first wire harness clip 122 can use their own elastic force to tightly clamp the connecting wire harness 140, thereby achieving a good fixing effect. At the same time, the elastic setting of the second wire harness clip 124 and the first wire harness clip 122 also facilitates the installation and disassembly of the connecting wire harness 140, making it convenient for staff to maintain or replace the connecting wire harness 140 when needed. Similarly, the wire harness clips described later in this application can also be made of elastic material to achieve similar technical effects, which will not be elaborated further below.

[0071] like Figure 12 and Figure 14 As shown, according to some embodiments of this application, the second wire harness clip 124 includes: a first upright plate 1242 and a second upright plate 1244. The first upright plate 1242 and the second upright plate 1244 of the same second wire harness clip 124 are disposed opposite to each other to define a wire passage space 124a, and the outer surface corner areas of the first upright plate 1242 and the second upright plate 1244 opposite to the wire passage space 124a are rounded with corners 124b.

[0072] Specifically, the first upright plate 1242 and the second upright plate 1244 are connected to the circuit board support 120 at the same end in the extension direction. The first upright plate 1242 and the second upright plate 1244 both extend away from the circuit board support 120, and are spaced apart and opposite to each other on the circuit board support 120. A wire passage space 124a is defined between the first upright plate 1242 and the second upright plate 1244 to accommodate the connecting wire harness 140. The first upright plate 1242 and the second upright plate 1244 can be on both sides of the connecting wire harness 140 to clamp and fix the connecting wire harness 140. In this embodiment, the corner areas of the outer surfaces of the first upright plate 1242 and the second upright plate 1244 facing away from the wiring space 124a are both rounded 124b to form rounded corners. The rounded corner 124b treatment makes the contact transition between the connecting wire harness 140 and the first upright plate 1242 and the second upright plate 1244 smooth. In related technologies, the outer edge of the wiring clip of the circuit board bracket 120 is designed with a right angle, which can easily scratch or tear the motor wires. In this embodiment, the rounded corner 124b treatment is used to make the first upright plate 1242 and the second upright plate 1244 make smooth contact with the connecting wire harness 140, which can protect the connecting wire harness 140 from being scratched or torn by sharp corners, thereby improving the durability of the connecting wire harness 140 and the overall reliability of the electrical control box 100.

[0073] Furthermore, in some specific embodiments of this application, the contours of the first upright plate 1242 and the second upright plate 1244 opposite to the circuit board support 120 are both constructed as arc contours, so that the ends of the first upright plate 1242 and the second upright plate 1244 are smooth, so as to further protect other components on the circuit board support 120 from damage to the ends of the first upright plate 1242 and the second upright plate 1244, and further improve the overall safety and lifespan of the electrical control box 100.

[0074] In other specific embodiments of this application, such as Figure 12 As shown, at least one reinforcing rib 124c is provided on the side of the first upright plate 1242 and the second upright plate 1244 opposite to each other. The reinforcing rib 124c can be configured to extend in the same direction as the first upright plate 1242 and the second upright plate 1244, or the reinforcing rib 124c can be configured as a grid-like reinforcing rib 124c extending in multiple directions. By providing the reinforcing rib 124c, it is beneficial to improve the structural strength and stiffness of the first upright plate 1242 and the second upright plate 1244, and to improve the durability and reliability of the first upright plate 1242 and the second upright plate 1244.

[0075] like Figure 12 and Figure 14As shown, according to some embodiments of this application, the second wire harness buckle 124 further includes a limiting plate 1246, which is disposed at the free end of the first upright plate 1242 and / or the second upright plate 1244, and the limiting plate 1246 extends toward the wire passage space 124a.

[0076] Specifically, the limiting plate 1246 can be configured such that the limiting plate 1246 is only provided on the free end of the first upright plate 1242 (i.e., the end of the first upright plate 1242 facing away from the circuit board support 120), while the limiting plate 1246 is not provided on the free end of the second upright plate 1244 (i.e., the end of the second upright plate 1244 facing away from the circuit board support 120), and the limiting plate 1246 on the first upright plate 1242 extends away from the first upright plate 1242 toward the wire passage space 124a; the limiting plate 1246 can also be configured such that the limiting plate 1246 is only provided on the free end of the second upright plate 1244, while the limiting plate 1246 is not provided on the free end of the first upright plate 1242, and the limiting plate 1246 on the second upright plate 1244 extends away from the first upright plate 1242 toward the wire passage space 124a; Position plate 1246 extends away from the second upright plate 1244 toward the wire passage space 124a; the arrangement of the limiting plate 1246 can also be configured such that the free ends of the first upright plate 1242 and the second upright plate 1244 are both provided with limiting plates 1246, the limiting plate 1246 on the first upright plate 1242 is configured as the first limiting plate 1246a, and the limiting plate 1246 on the second upright plate 1244 is configured as the second limiting plate 1246b. Then the first limiting plate 1246a extends away from the first upright plate 1242 toward the wire passage space 124a, and the second limiting plate 1246b extends away from the second upright plate 1244 toward the wire passage space 124a. The first limiting plate 1246a and the second limiting plate 1246b can be opposite each other. By setting a limiting plate 1246, the limiting plate 1246 can push the connecting wire harness 140 against the free ends of the second upright plate 1244 and the first upright plate 1242, so that the connecting wire harness 140 can be stably kept within the wire passage space 124a and will not come out from the free ends of the second upright plate 1244 and the first upright plate 1242, thereby ensuring the good limiting effect of the second wire harness buckle 124 on the connecting wire harness 140.

[0077] It is understood that the aforementioned limiting plate 1246 is opposite to the circuit board support 120. The limiting plate 1246 and the circuit board support 120 can abut against the connecting wire harness 140 in the first direction within the wire passage space 124a, thus limiting the connecting wire harness 140 in the first direction. The first upright plate 1242 is opposite to the second upright plate 1244. The first upright plate 1242 and the second upright plate 1244 can abut against the connecting wire harness 140 in the second direction within the wire passage space 124a, thus limiting the connecting wire harness 140 in the second direction. The second direction intersects with the first direction. In some embodiments, the second direction is orthogonal to the first direction. The limiting plate 1246, the circuit board bracket 120, the first upright plate 1242 and the second upright plate 1244 are arranged together around the connecting wire harness 140 in the wire passage space 124a to ensure that the connecting wire harness 140 will not move arbitrarily or deviate from the preset path in the wire passage space 124a, so as to ensure the limiting of the connecting wire harness 140.

[0078] like Figure 3 and Figure 4 As shown, according to some embodiments of this application, the electrical control box 100 further includes: a mounting frame 150, which is connected to the box body 110. The mounting frame 150 has a third wire harness buckle 152 disposed opposite to the second side plate 134. The third wire harness buckle 152 is adapted to guide the bending of the connecting wire harness 140 and extends along the extension direction of the second side plate 134 to the end of the mounting frame 150.

[0079] Specifically, the mounting frame 150 can be connected to the housing 110 and located on the side of the housing 110 away from the circuit board support 120. The mounting frame 150 can form a receiving cavity to accommodate the housing 110 and the circuit board support 120 and other components. The mounting frame 150 can provide good protection and support for the housing 110 and the circuit board support 120 and other components in the receiving cavity. A third wiring harness clip 152 is provided on the mounting frame 150. The third wiring harness clip 152 is disposed opposite to the second side plate 134. The third wiring harness clip 152 can surround the periphery of the connecting wiring harness 140 to limit the connecting wiring harness 140 passing through the first outlet hole 110b and the second outlet hole 120a. The third wiring harness clip 152 can guide the connecting wiring harness 140 passing through the first outlet hole 110b and the second outlet hole 120a to bend and extend along the extension direction of the second side plate 134 to the end of the mounting frame 150 for connection with external power supply or components. Furthermore, by guiding the connecting wiring harness 140 to bend through the third wiring harness clip 152, it is ensured that the connecting wiring harness 140 can form a continuous bend structure to effectively achieve a good waterproof effect on the inside of the electrical control box 100.

[0080] In addition, the third wire harness clip 152 limits the connection wire harness 140 that passes through the first outlet hole 110b and the second outlet hole 120a, which can further prevent the connection wire harness 140 from loosening or being damaged due to vibration or external force. It can further improve the installation stability of the connection wire harness 140 and protect the connection wire harness 140 from damage by other components, thereby further improving the stability and reliability of the connection wire harness 140 when transmitting signals or power, and further improving the management efficiency and neatness of the connection wire harness 140.

[0081] like Figure 4 and Figure 7 As shown, according to some embodiments of this application, a fourth wire harness buckle 154 is also provided at the end of the mounting frame 150. The fourth wire harness buckle 154 is used to limit the protruding end of the connecting wire harness 140, and the fourth wire harness buckle 154 is provided on both corner areas of the same end of the mounting frame 150 so that multiple connecting wire harnesses 140 are suitable for being led out from the same end of the mounting frame 150.

[0082] Specifically, the fourth wire harness clip 154 ​​is located at the end of the mounting frame 150 to limit the extension of the connecting wire harness 140 beyond the protruding end of the mounting frame 150. The fourth wire harness clip 154 ​​can cooperate with the third wire harness clip 152 to guide and fix the connecting wire harness 140, ensuring the neat arrangement, secure connection, and accurate connection position with external power sources or components of the connecting wire harness 140. The fourth wire harness clip 154 ​​is provided on both corner areas at the same end of the mounting frame 150. This arrangement allows multiple connecting wire harnesses 140 to be neatly led out from the same end of the mounting frame 150, facilitating subsequent connection and management.

[0083] Furthermore, in some specific embodiments of this utility model, such as Figure 3 As shown, the electrical control box 100 also includes a front cover 160 and a rear cover 170. The front cover 160 is located on the side of the circuit board bracket 120 away from the box body 110 and is connected to the mounting frame 150. The front cover 160 can close the accommodating space 110a of the box body 110. The rear cover 170 is located on the side of the mounting frame 150 away from the box body 110. The front cover 160 and the rear cover 170 can protect and install the components of the electrical control box 100.

[0084] like Figure 1 and Figure 2As shown, according to the second aspect embodiment of the present application, the air conditioner 10000 includes the electrical control box 100 described in the above embodiment. Since the air conditioner 10000 according to the second aspect embodiment of the present application includes the electrical control box 100 described in the above embodiment, the electrical control box 100 of the air conditioner 10000 has a water-blocking member 130 to protect and fix the connecting wire harness 140 and enhance the waterproof performance of the electrical control box 100. At the same time, the circuit board bracket 120 of the electrical control box 100 has a plurality of second wire harness clips 124 to further fix and protect the connecting wire harness 140, and the second wire harness clips 124 have a rounded corner 124b treatment area to protect the connecting wire harness 140 from scratches, thereby improving the working reliability and safety of the electrical control box 100, and thus improving the working performance and safety of the air conditioner 10000.

[0085] In addition, in some specific embodiments of this utility model, the air conditioner 10000 also includes a panel assembly 200, an air duct assembly 300, a fresh air assembly 400, a rear box assembly 500, a top cover 600, and a chassis 700. The panel assembly 200 is connected to and positioned opposite the rear box assembly 500, defining a receiving cavity between them. The panel assembly 200 and the rear box assembly 500 provide decoration, aesthetics, and protection for the internal components of the air conditioner 10000. The duct assembly 300, the fresh air assembly 400, and the electrical control box 100 are all housed within the receiving cavity. The duct assembly 300 enables the air conditioner 10000 to perform air intake and exhaust functions, while the fresh air assembly 400 enables the air conditioner 10000 to perform fresh air function. The top cover 600 and the chassis 700 are respectively located at the top and bottom of the panel assembly 200 and the rear box assembly 500, and enclose the receiving cavity. The top cover 600 and the chassis 700 provide support, fixation, and protection for the internal components of the air conditioner 10000, and also enhance the aesthetics of the exterior of the air conditioner 10000.
