In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.
[0061] Hereinafter, with reference to the accompanying drawings, an electrical control box 100 according to a first aspect embodiment of the present invention will be described.
[0062] Reference Figure 1 , Figure 2 and Figure 3 The control box 100 includes a circuit board 1 and a wiring frame 2. The circuit board 1 includes a substrate 11 and components 12 disposed on the substrate 11. One side of the substrate 11 in the thickness direction Z is a first side 1a. The components 12 include a first component 121 disposed on the first side 1a. The wiring frame 2 is disposed on the first side 1a. A wiring space 2a is provided on the side of the wiring frame 2 away from the substrate 11. The wiring frame 2 is disposed to avoid the first component 121. The height H1 of the wiring space 2a in the thickness direction Z is less than the height H2 of the first component 121.
[0063] The height H1 of the trace space 2a refers to the distance between the trace space 2a and the substrate 11 on the side closest to the substrate 11 (i.e., the bottom surface of the trace space 2a). The height H2 of the first component 121 refers to the distance between the first component 121 and the substrate 11 on the side furthest from the substrate 11 (i.e., the top surface of the first component 121).
[0064] The cable tray 2 is located on the first side 1a and avoids the first component 121. Avoidance means that the cable tray 2 is set up with the position of the first component 121 in mind. It is set away from the first component 121, or it is set around the first component 121, or a first avoidance gap 21 is set to avoid the first component 121. This avoids spatial conflict with the first component 121, thereby reducing the probability of damage such as squeezing or collision to the first component 121 during the wiring process, extending the service life of the first component 121, and thus ensuring the normal operation of the entire electrical control box 100.
[0065] Among them, the cable tray 2 is a structural component used to organize and arrange the internal wires 41 of the electrical control box 100. The cable tray 2 has the functions of fixing, organizing, classifying and isolating the wires from other components (such as components 12), thereby improving the standardization and manageability of the wiring. The form of the cable tray 2 is not limited. For example, it can be a frame-type cable tray, a trough-type cable tray, a tray-type cable tray, etc.
[0066] In related technologies, the air conditioner's control box is the core control component of the air conditioning system, responsible for regulating parameters such as the air conditioner's operating mode, temperature, and fan speed to ensure the safe and stable operation of the equipment. However, as the functions of air conditioners increase, the number of components that the control box needs to connect to also increases, leading to a greater number of wiring traces in the control box. The wiring of the control box is usually located on the periphery of the circuit board. When the number of traces increases, the wiring space required on the periphery of the circuit board increases, resulting in a larger outer dimension of the control box.
[0067] In the technical solution of this application, the wiring frame 2 and the first component 121 are disposed on the same side of the substrate 11. The wiring frame 2 is disposed to avoid the first component 121, and the height H1 of the wiring space 2a along the thickness direction Z is less than the height H2 of the first component 121. This shows that the wiring frame 2 is disposed by utilizing the height space of the first component 121, which improves the utilization rate of the internal space of the electrical control box 100, reduces the wiring around the circuit board 1, thereby reducing the outer contour size of the electrical control box 100 and making the overall structure of the electrical control box 100 more compact.
[0068] In addition, a wiring space 2a is provided on the side of the wiring rack 2 away from the substrate 11, which provides a dedicated area for organizing and arranging the wires 41 inside the electrical control box 100. The wiring rack 2 isolates the wires 4 from the components 12 located on the first side 1a of the substrate 11, thereby making the wiring more neat and orderly, less likely to interfere with or entangle with the components 12, reducing the tangling and messiness of the wires 41, reducing the probability of short circuits and other faults in the wires 41, improving the stability and reliability of the electrical control box 100, and also facilitating subsequent maintenance and repair work.
[0069] For example, the control box 100 is used in a window air conditioner 1000, and the outdoor unit 200 of the window air conditioner 1000 includes the control box 100, such as... Figure 14As shown, the electrical control box 100 is located inside the outdoor unit 200 of the window air conditioner 1000. The electrical control box 100 is positioned between the air inlet area 220 and the heat exchanger, with its main plane facing the air inlet area 220 of the outdoor unit 200, thus partially obstructing the airflow from the air inlet area 220 to the heat exchanger. In the technical solution of this application, by reducing the outer contour dimensions of the electrical control box 100, the obstruction area of the electrical control box 100 on the air inlet area 220 inside the air conditioner is reduced, thereby increasing the air intake volume and allowing more airflow to flow smoothly to the heat exchanger, improving the heat exchange efficiency of the window air conditioner 1000.
[0070] In some embodiments, refer to Figure 3 and Figure 4 The first side 1a is provided with multiple components 12, and the first component 121 is the tallest component 12 among all the components 12 provided on the first side 1a. That is, the wiring frame 2 is provided on the side of the tall component 12, which makes full use of the empty space on this side of the substrate 11. In other words, the setting space of the wiring frame 2 makes full use of the space in the height direction of the components 12 in the electrical control box 100, so that the wiring frame 2 itself does not need to occupy the space around the circuit board 1 or occupies less space, thereby making the overall outer contour size of the electrical control box 100 smaller.
[0071] In some embodiments, refer to Figure 3 and Figure 4 The first component 121 is capacitor 121a. Capacitor 121a is usually large in size, tall, and has long leads. It is tall in the thickness direction Z of the circuit board 1. By placing the wiring frame 2 and capacitor 121a on the same side, the internal space of the control box 100 in the height direction of capacitor 121a is utilized, so that the wiring frame 2 itself does not need to occupy any or less additional space, thereby making the overall outer contour size of the control box 100 smaller.
[0072] In some embodiments, refer to Figure 3 and Figure 4 The first side 1a is provided with multiple components 12. The first component 121 is the tallest component 12 among all the components 12 provided on the first side 1a, and the first component 121 is a capacitor 121a. That is, the capacitor 121a is the tallest component 12 among all the components 12 provided on the first side 1a. Thus, the space of the wiring frame 2 makes full use of the space in the height direction of the capacitor 121a, thereby making the overall structure of the electrical control box 100 more compact.
[0073] In some embodiments, refer to Figure 4 and Figure 5The cable tray 2 defines a first clearance notch 21 extending along the thickness direction Z of the plate, through which the first component 121 passes. Thus, the cable tray 2 at least partially surrounds the first component 121. Compared to the cable tray 2 completely avoiding the first component 121, the cable tray 2 defines a larger area by defining the first clearance notch 21 to avoid the first component 121. This allows for a larger cable tray area, providing more options for the cable routing path of the wire 41, thus facilitating cable organization, reducing tangling and messiness of the wires 41, improving the stability and reliability of the electrical control box 100, and also facilitating subsequent maintenance and repair. Furthermore, by incorporating the component 12 located on the first side 1a and hidden on the side of the wiring frame 2 facing the substrate 11, the wiring frame 2 defines a first clearance notch 21 extending along the thickness direction Z, which allows the wiring frame 2 to at least partially surround the first component 121, thereby increasing the area of the wiring frame 2 covering and hiding the component 12 and improving the reliability and stability of the electrical control box 100.
[0074] For example, the first component 121 is a capacitor 121a and is located in the middle of the circuit board 1. The wiring frame 2 defines a first clearance notch 21 that runs through the thickness direction Z of the board. The first clearance notch 21 partially surrounds the capacitor 121a. The capacitor 121a passes through the first clearance notch 21 in the thickness direction Z of the board. The wiring path of the wire 41 can be set around the capacitor 121a, and the wiring path of the wire 41 is more flexible.
[0075] In some embodiments, refer to Figure 3 At least one component 12 located on the first side 1a is hidden on the side of the wiring frame 2 facing the substrate 11. "Hidden" means that the component 12 is placed on the side of the wiring frame 2 facing the substrate 11, so that the projection of the wiring frame 2 onto a plane perpendicular to the board thickness direction Z covers the component 12. That is, these components 12 are not directly visible on the side of the wiring frame 2 facing away from the substrate 11. It is worth noting that this hiding is not a complete seal, but rather a relative concealment of the component 12 achieved through the shielding and spatial arrangement of the wiring frame 2. Thus, the wiring space 2a on the side of the wiring frame 2 facing away from the substrate 11 is isolated from the component 12 by the wiring frame 2. On the one hand, this reduces the probability of damage to the component 12 during wire routing (e.g., the wire 41 scratching or bending the pins of the component 12). On the other hand, it also reduces problems such as the wire 41 embedding in the gaps between components 12 or tangling with components 12, improving the reliability and stability of the control box 100.
[0076] In some embodiments, refer to Figure 3 The components 12 located on the first side 1a and hidden on the side of the wiring frame 2 facing the substrate 11 include high-voltage components and / or semiconductor components.
[0077] High-voltage electrical components refer to electronic devices that withstand high voltage and large current during operation. Examples of common high-voltage electrical components include transformers, relays, contactors, high-power resistors, inductors, etc. These components typically have high voltage and current. Hiding them under the cable tray 2 prevents operators from accidentally touching them during wiring, reducing the risk of electric shock and improving the safety of the control box 100. Furthermore, high-voltage electrical components generate large currents during operation, easily producing strong electromagnetic fields. By hiding these components on the side of the cable tray 2 facing the substrate 11, the wiring 41 is isolated from the high-voltage components, reducing electromagnetic interference and improving the overall electrical stability of the control system.
[0078] Semiconductor components are electronic devices made using semiconductor materials. Common semiconductor components include diodes, transistors, and integrated circuit chips. Semiconductor components are sensitive to environmental conditions such as temperature, humidity, and dust. The semiconductor components are hidden under the wiring rack 2, which provides them with a relatively stable working environment. The wiring rack 2 reduces dust accumulation on the surface of the semiconductor components, thus reducing the possibility of malfunctions such as decreased insulation performance and short circuits caused by dust.
[0079] In some embodiments, refer to Figure 3 and Figure 4 The first side 1a is provided with a terminal block 131, and the wire 41 connected to the terminal block 131 is routed through the wiring space 2a. By setting the terminal block 131 on the first side 1a of the substrate 11 to connect the wire 41 to the substrate 11, a larger contact area and a stable electrical connection can be provided, and the wire 41 can be easily plugged in and unplugged. After the wire 41 is led out from the terminal block 131, it can be routed through the wiring space 2a according to a set path, reducing the situation where the wire 41 is scattered or tangled. The wiring space 2a provides a relatively independent and fixed channel for the wire 41, reducing the displacement or wear of the wire 41 due to vibration, shaking and other factors during equipment operation.
[0080] In some embodiments, refer to Figure 4 and Figure 5 The cable tray 2 defines a second clearance notch 22 extending along the thickness direction Z of the plate, and at least one terminal block 131 is provided corresponding to the second clearance notch 22. The second clearance notch 22 can be a closed notch or an open notch; the shape of the second clearance notch 22 is not limited and can be set according to the shape of the terminal block 131 and the wiring requirements. For example, the shape of the second clearance notch 22 can be rectangular, polygonal, circular, etc.
[0081] In the above technical solution, on the one hand, the setting of the second clearance notch 22 allows the wire 41 connected to the terminal 131 to pass directly through the cable tray 2 with the help of the second clearance notch 22, reducing the winding of the wire 41 and improving the space utilization rate inside the electrical control box 100; on the other hand, by setting the second clearance notch 22 to avoid the terminal 131, the area covered by the cable tray 2 is larger, that is, the mating area between the cable tray 2 and the box 3 or the circuit board 1 is larger, thereby making the installation of the cable tray 2 more stable.
[0082] For example, such as Figure 4 As shown, by setting a second clearance notch 22, the edge of the cable tray 2 can extend to the edge of the box 3. The edge of the box 3 is provided with a cable tray buckle 311, which facilitates the installation and fixation of the cable tray 2 and the box 3.
[0083] In some embodiments, refer to Figure 4 and Figure 5 There are multiple second clearance notches 22, which are spaced apart, and each second clearance notch 22 is provided with at least one terminal 131. For example, each second clearance notch 22 may be provided with one, two, three, four or more terminal 131.
[0084] In the above technical solution, the multiple second clearance gaps 22 set at intervals can make full use of the space of the cable tray 2, so that the terminals 131 are reasonably distributed, thereby optimizing the path of the wires 41, accommodating more wires 41 in a limited space, and making the wires 41 more orderly, reducing the extra space occupied by the crossing and tangling of the wires 41, and improving the utilization rate of the internal space of the electrical control box 100.
[0085] In some embodiments, refer to Figure 5 and Figure 6 The cable tray 2 has a cable exit portion 23 on the side opposite to the substrate 11. A cable exit groove 231 is formed on the cable exit portion 23, and the cable exit groove 231 extends to the edge of the cable tray 2. Figure 3 The wire 41, which is routed through the wiring space 2a, extends out of the wiring rack 2 through the cable outlet 231.
[0086] In the above technical solution, a cable outlet groove 231 extending to the edge of the cable tray 2 is formed on the cable outlet section 23, which provides a clear cable outlet path for the wire 41, so that the wire 41 extends directly and smoothly out of the cable tray 2 in a predetermined direction and position, thereby improving the efficiency and quality of cable routing; and the cable outlet groove 231 can fix and protect the wire 41, reducing the wear of the wire 41.
[0087] In some embodiments, refer to Figure 7 and Figure 8The electrical control box 100 includes a box body 3, which has a first mounting cavity 3a and a second mounting cavity 3b. The circuit board 1 is disposed in the first mounting cavity 3a, and the second mounting cavity 3b is located at the edge of the first mounting cavity 3a. A sealing element 3b1 is provided in the second mounting cavity 3b, which defines a wire passage hole 3b11. Figure 6 The cable outlet 23 is located near the seal 3b1 of the cable tray 2. The wire 41 that extends out of the cable tray 2 through the cable outlet groove 231 extends out of the box 3 through the cable hole 3b11.
[0088] In the above technical solution, the cable tray 2's outlet section 23 is close to the seal 3b1, allowing the wire 41 to extend from the cable tray 2 through the outlet groove 231 and directly through the wire hole 3b11 on the seal 3b1 to exit the box 3. This reduces the length of the wire 41 within the electrical control box 100. Since the outlet positions of the wire 41 are concentrated on one side where the outlet groove 231 is located, the electrical control box 100 can be connected to other components more quickly and accurately, reducing the connection difficulty caused by dispersed outlets. Furthermore, concentrating the outlet on one side simplifies the wiring path, making it easier to locate the connection position and direction of the wire 41 during maintenance, thus improving maintenance efficiency and accuracy. The seal 3b1 prevents the interior of the electrical control box 100 from being corroded by water, thereby improving the electrical reliability of the electrical control box 100.
[0089] For example, the cable outlet 23 is located at the first edge 2b of the cable tray 2. There may be a certain distance between the first edge 2b of the cable tray 2 and the seal 3b1. For example, the distance may be less than 10mm, such as 10mm, 8mm, 6mm, 4mm, 2mm, 1mm, etc.
[0090] In some embodiments, refer to Figure 5 The cable outlet 23 is located at the first edge 2b of the cable tray 2 and defines a plurality of cable outlet slots 231 that are spaced apart along the length extension direction of the first edge 2b. Each cable outlet slot 231 extends along the direction in which the first edges 2b intersect.
[0091] In the above technical solution, the cable outlet 23 is set at the first edge 2b of the cable tray 2, which realizes the centralized cable outlet of the wire 41, reduces the connection difficulty caused by the dispersed cable outlet, and the centralized cable outlet of the wire 41 is more neat and orderly; by defining multiple cable outlet slots 231 at intervals in the cable outlet 23, the isolation of the wire 41 is realized.
[0092] For example, wires 41 can be divided into multiple strands 4 according to their different strengths, reducing mutual interference (such as electromagnetic interference) between wires 41 of different strengths and improving the operational reliability of different wires 41. In addition, when the wire harnesses 4 are separated, each wire harness 4 can be individually identified and managed. For example, the function, number, and other information of the wire harness 4 can be marked on different cable trays 231, which facilitates the identification and operation of wires 41 during the installation and maintenance of the electrical control box 100.
[0093] In some embodiments, refer to Figure 4 , Figure 5 and Figure 6 The first side 1a is provided with a terminal block 131. Wires 41 connected to the terminal block 131 are routed through the wiring space 2a and extend out of the cable tray 2 through the cable outlet 231. The cable tray 2 includes a frame plate 24, and the cable outlet 23 and the frame plate 24 are arranged along a first direction F1. Multiple terminal blocks 131 are spaced around the frame plate 24. Multiple terminal blocks 131 arranged adjacent to each other along the surrounding direction form a terminal group 13. Wires 41 extending from one terminal group 13 form a wire bundle 4 and exit through the same cable outlet 231. The terminal group 13 can be partitioned according to the function of the terminal blocks 131. For example, high-voltage terminal blocks 131 and low-voltage terminal blocks 131 can be placed on different sides or in different areas to reduce interference between high-voltage and low-voltage circuits.
[0094] In the above technical solution, multiple terminals 131 are spaced around the shelf 24, making full use of the space around the shelf 24. This allows for the accommodation of more terminals 131, meeting the connection needs of more wires 41. The spaced arrangement of the terminals 131 ensures sufficient electrical clearance between each terminal 131, reducing electrical safety risks caused by short circuits or leakage of the terminals 131. Multiple terminals 131 arranged adjacent to each other along the surrounding direction form a terminal group 13. Each wire 41 extending from a terminal group 13 forms a wire bundle 4 and exits through the same outlet groove 231. This simplifies the wiring path of the wires 41 on the cable tray 2, reducing many wiring paths of the wires 41 to several wiring paths of wire bundles 4. This facilitates centralized management of the wiring of the wires 41 and improves the efficiency of the wiring of the wires 41.
[0095] In some embodiments, refer to Figure 5 and Figure 6 The side of the rack section 24 facing away from the base plate 11 has multiple wire clips 241, each wire clip 241 used to gather multiple wires 41 in a wire bundle 4. As a result, multiple wires 41 are gathered into a single wire bundle 4, making the wiring on the entire cable tray 2 more neat and orderly; in addition, the wire clips 241 reduce the possibility of the wires 41 becoming loose due to equipment vibration, movement or external pulling, and improve the reliability of the wire 41 connection.
[0096] In some embodiments, refer to Figure 5 and Figure 6 The frame plate portion 24 has a third side 24a and a fourth side 24b on its two sides in the second direction F2, respectively. The second direction F2 is perpendicular to the first direction F1 and both are perpendicular to the plate thickness direction Z. Figure 4 The bracket section 24 is provided with multiple terminals 131 on the third side 24a, the fourth side 24b and the side away from the outgoing part 23 in the first direction F1.
[0097] In the above technical solution, multiple wiring terminals 131 are provided on the third side 24a, the fourth side 24b, and the side away from the outgoing part 23 on the first direction F1 of the bracket part 24. This increases the number of positions for the wiring terminals 131, thereby allowing more lines to be connected within a limited space and improving the integration of the electrical control box 100. Furthermore, with the development of technology and the continuous increase in equipment functions, it may be necessary to connect more lines and electrical components. The wiring terminals 131 provided on multiple sides facilitate the expansion and upgrading of the electrical control box 100.
[0098] In some embodiments, refer to Figure 5 and Figure 6 Multiple cable trays 231 are arranged along the second direction F2, and multiple terminal groups 13 are arranged as a whole along the second direction F2. In any two terminal groups 13, the cable tray 231 through which the extended wire harness 4 of the terminal group 13 closer to the third side 24a passes is positioned closer to the third side 24a than the cable tray 231 through which the extended wire harness 4 of the terminal group 13 closer to the fourth side 24b passes. For example, if the second direction F2 is a vertical direction, in any two terminal groups 13, the cable tray 231 through which the extended wire harness 4 of the upper terminal group 13 passes is higher than the cable tray 231 through which the extended wire harness 4 of the lower terminal group 13 passes.
[0099] In the above technical solution, multiple cable trays 231 and terminal groups 13 are arranged along the second direction F2, so that multiple terminal groups 13 can correspond to multiple cable trays 231. The wires 41 connected in each terminal group 13 can form a wire bundle 4. Each wire bundle 4 can correspond to the cable tray 231 according to the arrangement order in the second direction F2, thereby reducing the tangling and crossing of the wire bundle 4, improving the neatness of the wiring, and facilitating subsequent maintenance and management.
[0100] In some embodiments, refer to Figure 6The terminal 131 located on the third side 24a and closest to the outlet section 23 is the first terminal 1311. The first terminal 1311 is connected to the power cord 411 and exits separately through an outlet trough 231. On the one hand, the power cord 411 usually carries a large current, so its diameter is relatively thick, making it inconvenient to exit together with other thinner wires 41. On the other hand, if the power cord 411 is mixed with other wires 41, a short circuit can easily occur if the insulation layer is damaged, damaging the components connected to other wires 41. The first terminal 1311 connects to the power cord 411 and exits separately through an outlet trough 231, reducing the risk of short circuits burning out other components of the equipment and ensuring the safe operation of the equipment.
[0101] In some embodiments, the terminal 131 located on the fourth side 24b and closest to the outlet portion 23 is a second terminal 1321. The second terminal 1321 is positioned closer to the third side 24a than the other terminals 131 located on the fourth side 24b. The wire 41 connected to the second terminal 1321 and the nearby wire harness 4 exit from the same outlet slot 231. For example, the second terminal 1321 is an internal motor terminal, and the wire connected to the second terminal 1321 is an internal motor wire. The internal motor wire and the nearby third wire harness 4c exit from the same outlet slot 231. Therefore, by using a nearby outlet configuration for the second terminal 1321, the length of the wire 41 connected to the second terminal 1321 and the cross-tangle with other wires 41 can be reduced.
[0102] In some embodiments, refer to Figure 4 and Figure 5 The cable outlet 23 and the support plate 24 together form a first clearance notch 21 that runs through the plate thickness direction Z, and the first component 121 passes through the first clearance notch 21.
[0103] In the above technical solution, compared to the cable tray 2 completely avoiding the first component 121, the cable tray 2 can have a larger area, thus allowing for more cable fixing structures (such as the second wire clip 2412 and the fourth cable outlet 2314), which is more conducive to cable management, reduces the tangling and messiness of the wires 41, and improves the stability and reliability of the electrical control box 100. Furthermore, considering that the component 12 is located on the first side 1a and hidden on the side of the cable tray 2 facing the substrate 11, the cable tray 2 defines a first avoidance notch 21 extending along the thickness direction Z, allowing the cable tray 2 to at least partially surround the first component 121, thereby increasing the area of the cable tray 2 covering and hiding the component 12, and improving the reliability and stability of the electrical control box 100.
[0104] In some embodiments, refer to Figure 1 , Figure 2 and Figure 3The electrical control box 100 includes a box body 3, which includes a box base 31 and a box cover 32 that overlap each other along the thickness direction Z. The circuit board 1 is disposed inside the box body 3. The first side 1a is the side of the substrate 11 facing the box cover 32. The circuit board 1 is mounted on the box base 31. The cable tray 2 is mounted on the box base 31 or on the circuit board 1.
[0105] For example, the circuit board 1 is mounted on the housing 31, and the inner periphery of the housing 31 is provided with circuit board clips 312 and circuit board latches 313 to fix the circuit board 1.
[0106] In the above technical solution, the box body 3 of the electrical control box 100 includes a box base 31 and a box cover 32 that overlap each other along the thickness direction Z. The circuit board 1 is installed in the box base 31. The box base 31 provides stable support and fixed space for the circuit board 1. The box base 31 and the box cover 32 can protect the circuit board 1, prevent external dust, moisture and other substances from entering, and improve the reliability and service life of the electrical control box 100.
[0107] In some embodiments, refer to Figure 9 , Figure 10 and Figure 11 The cover 32 includes a first cover portion 321 and a second cover portion 322. The second cover portion 322 protrudes relative to the first cover portion 321 to define a receiving groove 3221 that opens toward the circuit board 1. Figure 3 The cable tray 2 and the first component 121 are both housed in the receiving slot 3221. A third clearance notch 3211 is formed on the first cover 321. A heat sink 14 is provided on the circuit board 1. The heat sink 14 is located on the first side 1a and passes through the third clearance notch 3211.
[0108] In the above technical solution, the second cover 322 protrudes relative to the first cover 321 to form a receiving groove 3221, which can increase the volume of the control box 100 without increasing the planar size of the control box 100, providing a space for the wiring frame 2 and the first component 121, making the internal structure more compact; the heat sink 14 on the circuit board 1 is located on the first side 1a and passes through the third clearance notch 3211 on the first cover 321, so that the heat sink 14 can directly exchange heat with the external environment, realize heat dissipation of key heat-generating components on the circuit board 1, effectively dissipate the heat generated by the circuit board 1, prevent the circuit board 1 from being damaged due to overheating, and extend the service life of the control box 100.
[0109] Combination Figure 14 The window air conditioner 1000 according to the second aspect of the present invention includes an electrical control box 100 according to any embodiment of the first aspect of the present invention.
[0110] According to the embodiment of the present utility model, the window air conditioner 1000 reduces the space occupied by the control box 100 in the window air conditioner 1000 by providing the control box 100 mentioned in the first aspect.
[0111] In some embodiments, combined with Figure 14 The control box 100 is vertically mounted, with the wiring exiting from its lower part. "Vertically mounted" means that the thickness direction Z of the circuit board 1 inside the control box 100 is approximately horizontal.
[0112] In the above technical solution, the vertically arranged electrical control box 100 can make full use of the internal height space of the window air conditioner 1000, thereby reducing the floor space occupied by the window air conditioner 1000 and making the overall structure of the window air conditioner 1000 more compact. The lower wiring of the electrical control box 100, compared with the upper wiring, can reduce the possibility of dust entering the electrical control box 100 from the top, thereby effectively protecting the components 12 inside the electrical control box 100. In addition, the vertical arrangement and lower wiring can reduce water intrusion into the electrical control box 100 and improve the waterproof performance of the electrical control box 100.
[0113] In some embodiments, combined with Figure 14 The window air conditioner 1000 includes an outdoor unit 200 suitable for installation on the outdoor side and an indoor unit 300 suitable for installation on the indoor side. The indoor unit 300 and the outdoor unit 200 are spaced apart to form an installation clearance space 400 between them. The side of the outer casing of the outdoor unit 200 facing the installation clearance space 400 is a rear casing wall 210, and an air inlet area 220 is formed on the rear casing wall 210. The electrical control box 100 is located inside the outer casing of the outdoor unit 200 near the rear casing wall 210, and the base plate 11 is arranged parallel to the rear casing wall 210. For example, during installation, the indoor unit 300 is located indoors, and the outdoor unit 200 is located outdoors. The installation clearance space 400 is used to accommodate a window sash or a wall, depending on the opening direction.
[0114] In the above technical solution, the electrical control box 100 is located inside the outer casing of the outdoor unit 200 near the rear shell wall 210, and the base plate 11 is set parallel to the rear shell wall 210. This makes full use of the height space inside the window air conditioner 1000, thereby reducing the floor space occupied by the outdoor unit 200 and improving the space utilization rate. It also reduces the area of the air intake area 220 blocked by the electrical control box 100 inside the air conditioner, thereby reducing the air intake resistance of the window air conditioner 1000 and improving the heat exchange efficiency of the window air conditioner 1000.
[0115] Below, please refer to the appendix. Figures 1-13 This application describes an electrical control box 100 according to a specific embodiment of the present application.
[0116] The electrical control box 100 includes a circuit board 1 and a wiring frame 2. The circuit board 1 includes a substrate 11 and components 12 disposed on the substrate 11. One side of the substrate 11 in the thickness direction Z is a first side 1a. The components 12 include a first component 121 disposed on the first side 1a. The first component 121 is a capacitor 121a, and the capacitor 121a is the component 12 with the largest height among all the components 12 disposed on the first side 1a. The wiring frame 2 defines a first clearance notch 21 that runs through the thickness direction Z. The capacitor 121a passes through the first clearance notch 21. Some high-power components and semiconductor components are disposed on the first side 1a and hidden on the side of the wiring frame 2 facing the substrate 11. A wiring space 2a is provided on the side of the wiring frame 2 away from the substrate 11. The height H1 of the wiring space 2a in the thickness direction Z is less than the height H2 of the first component 121. A terminal 131 is provided on the first side 1a. The wire 41 connected to the terminal 131 is routed through the wiring space 2a.
[0117] The electrical control box 100 includes a box body 3, which includes a box base 31 and a box cover 32 that overlap each other along the thickness direction Z. A circuit board 1 is disposed inside the box body 3. The first side 1a is the side of the substrate 11 facing the box cover 32. The circuit board 1 is mounted on the box base 31. The cable tray 2 is mounted on the box base 31. The box body 3 has a first mounting cavity 3a and a second mounting cavity 3b. The circuit board 1 is disposed in the first mounting cavity 3a. The second mounting cavity 3b is located at the edge of the first mounting cavity 3a. A sealing member 3b1 is provided in the second mounting cavity 3b. The sealing member 3b1 defines a wire passage hole 3b11. A wire exit 23 is disposed on the cable tray 2 near the sealing member 3b1. The wire 41 that extends out of the cable tray 2 through the wire exit groove 231 extends out of the box body 3 through the wire passage hole 3b11.
[0118] The cover 32 includes a first cover portion 321 and a second cover portion 322. The second cover portion 322 protrudes relative to the first cover portion 321 to define a receiving groove 3221 that opens toward the circuit board 1. The cable tray 2 and the first component 121 are both housed in the receiving groove 3221. A third clearance notch 3211 is formed on the first cover portion 321. A heat sink 14 is provided on the circuit board 1. The heat sink 14 is located on the first side 1a and passes through the third clearance notch 3211.
[0119] The cable tray 2 defines a second clearance notch 22 that runs through the plate thickness direction Z. There are multiple second clearance notches 22 that are spaced apart. Each second clearance notch 22 is provided with at least one terminal block 131.
[0120] The cable outlet 23 is located at the first edge 2b of the cable tray 2 and defines a plurality of cable outlet slots 231 that are spaced apart along the length extension direction of the first edge 2b. Each cable outlet slot 231 extends along the direction where the first edges 2b intersect. The cable outlet slot 231 extends to the edge of the cable tray 2, and the wire 41 that is routed through the cable space 2a extends out of the cable tray 2 through the cable outlet slot 231.
[0121] The cable tray 2 includes a tray plate 24, a cable outlet 23, and the tray plate 24 arranged along a first direction F1. The tray plate 24 has a third side 24a and a fourth side 24b on two sides in a second direction F2. The second direction F2 is perpendicular to the first direction F1 and also perpendicular to the plate thickness direction Z. The tray plate 24 has multiple terminals 131 on the third side 24a, the fourth side 24b, and the side in the first direction F1 away from the cable outlet 23. Multiple terminals 131 arranged adjacent to each other along the surrounding direction form a terminal group 13. Wires 41 extending from a terminal group 13 form a wire bundle 4 and exit through the same cable outlet groove 231.
[0122] Multiple cable trays 231 are arranged along the second direction F2, and multiple terminal groups 13 are arranged along the second direction F2 as a whole. Among any two terminal groups 13, the cable tray 231 through which the extended wire harness 4 of the terminal group 13 closer to the third side 24a passes is set closer to the third side 24a than the cable tray 231 through which the extended wire harness 4 of the terminal group 13 closer to the fourth side 24b passes.
[0123] Among them, the terminal 131 located on the third side 24a and closest to the outlet part 23 is the first terminal 1311. The first terminal 1311 is the power cord connection terminal and is connected to the power cord 411. The power cord 411 is output separately from the first outlet groove 2311. The third side 24a is also provided with a four-way valve connection terminal 1312, a one-way valve connection terminal 1313 and a negative ion connection terminal 1314. The above terminals 131 are respectively connected to the four-way valve line 412, the one-way valve line 413 and the negative ion line 414. The above wires 41 form a second wire bundle 4b and are output from the second outlet groove 2312.
[0124] A terminal 131 located on the third side 24a and closest to the bracket section 24 is an electromagnetic expansion valve terminal 1320. On the side of the first direction F1 away from the outlet section 23, there are display panel terminal 1318, temperature sensor terminal 1319, and communication terminal 1317. The above terminals 131 are respectively connected to the electromagnetic expansion valve line 420, display panel line 418, temperature sensor line 419, and communication line 417. These wires 41 are all low-voltage wires. They are gathered together by the first wire clip 2411 to form a third wire bundle 4c and exit from the third outlet groove 2313.
[0125] The terminal 131 located on the fourth side 24b and closest to the outlet section 23 is the second terminal 1321. The second terminal 1321 is the internal motor terminal. The wire 41 connected to the second terminal 1321 is the internal motor wire 421. The internal motor wire 421 is also a low-voltage wire and exits from the third outlet trough 2313 with the nearby third wire harness 4c.
[0126] The fourth side 24b of the frame section 24 is provided with an external motor wiring terminal 1316 and a compressor wiring terminal 1315. The above wiring terminals 131 are respectively connected to the external motor wire 416 and the compressor wire 415. They are gathered together by the second wire buckle 2412 to form a fourth wire bundle 4d, and after being bent at the second wire buckle 2412 to avoid the capacitor 121a, the wires are discharged from the fourth wire outlet slot 2314.
[0127] The window air conditioner 1000 includes an outdoor unit 200 suitable for installation on the outdoor side and an indoor unit 300 suitable for installation on the indoor side. The indoor unit 300 and the outdoor unit 200 are spaced apart to form an installation clearance space 400 between them. The side wall of the outer casing of the outdoor unit 200 facing the installation clearance space 400 is a rear casing wall 210. An air inlet area 220 is formed on the rear casing wall 210. The electrical control box 100 is vertically installed. The electrical control box 100 has wires coming out from its lower part. The electrical control box 100 is located inside the outer casing of the outdoor unit 200 on the side close to the rear casing wall 210, and the base plate 11 is installed parallel to the rear casing wall 210.
[0128] Therefore, the electrical control box 100 utilizes the height dimension space of the capacitor 121a on the circuit board 1 to support the wiring rack 2, so that the wiring is not parallel to the circuit board 1, reducing the area of the electrical control box 100 on the plane perpendicular to the board thickness direction Z, and achieving a compact structure of the electrical control box 100. This results in a smaller area of the electrical control box 100 blocking the air intake area 220 inside the outdoor unit 200 of the window air conditioner 1000. The wiring rack 2 inside the electrical control box 100 has multiple wiring channels with strong and weak current wires separated and fixed, avoiding mutual interference between different wires 41 and improving the electrical safety performance of the electrical control box 100. The strong current components, semiconductor devices and other components 12 inside the electrical control box 100 are isolated from the wires 41 through the wiring rack 2, effectively protecting the components 12 and the wires 41.
