[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

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.

[0033] The outdoor unit 100 of the air conditioner according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0034] According to an embodiment of the present utility model, the outdoor unit 100 of the air conditioner is as follows: Figure 1 and Figure 2 As shown, the outdoor unit 100 of the air conditioner includes: a housing 1, a terminal block 2, and a circuit board 3. The housing 1 includes a front panel 11 and a side panel 12. The rear side of the front panel 11 has a fan cavity 100a and a compressor cavity 100b. The side panel 12 is located on the side of the compressor cavity 100b away from the fan cavity 100a. The terminal block 2 is located on the side panel 12. The circuit board 3 is located inside the compressor cavity 100b. The side of the circuit board 3 facing the front panel 11 has a high-voltage wire connection part 31 and a low-voltage wire connection part 32. The high-voltage wire 6 connected to the high-voltage wire connection part 31 extends to the terminal block 2. The high-voltage wire connection part 31 and the low-voltage wire connection part 32 are respectively located in different areas of the circuit board 3.

[0035] The outdoor unit 100 of the air conditioner includes a housing 1, which is the outer contour of the outdoor unit 100 and can protect the internal wiring terminal 2, circuit board 3, etc. The housing 1 has a fan cavity 100a and a compressor cavity 100b. The plate forming the housing 1 includes a front panel 11 and a side panel 12. The side panel 12 is located on one side of the compressor cavity 100b and is positioned away from the fan cavity 100a relative to the compressor cavity 100b.

[0036] Terminal block 2 is used for connecting wire harnesses, or it can be used to limit the terminals of mated wire harnesses. Terminal block 2 acts as an intermediate adapter. The wire harness of the outdoor unit 100 of the air conditioner extends to terminal block 2. The external wire harness connected to the outdoor unit 100 of the air conditioner can be directly connected to terminal block 2, so that the external wire harness can be connected to the internal wire harness of the outdoor unit 100 of the air conditioner.

[0037] Understandably, the process of connecting the external wiring harness to the internal wiring harness of the outdoor unit 100 is performed during installation at the point of use. By placing the terminal block 2 on the side panel 12, wiring can be easily performed from near the side panel 12, simplifying the wiring operation of the outdoor unit 100.

[0038] The high-voltage wire connection part 31 is used to connect the high-voltage wire 6, and the low-voltage wire connection part 32 is used to connect the low-voltage wire 7. For example, the high-voltage wire 6 includes a power supply line, a fan drive line, a compressor drive line, a four-way valve drive line, etc. For example, the low-voltage wire 7 includes a sensor line for collecting temperature and pressure, an electronic expansion valve line, and an external communication line, etc.

[0039] The wiring of the high-voltage wire connection part 31 and the low-voltage wire connection part 32 is carried out during the production and assembly process of the outdoor unit 100 of the air conditioner. Therefore, the high-voltage wire connection part 31 and the low-voltage wire connection part 32 are set on the side facing the front panel 11, which provides a larger wiring operation space for the high-voltage wire connection part 31 and the low-voltage wire connection part 32, which is convenient for production and later maintenance.

[0040] The high-voltage wire 6, connected to the high-voltage wire connection part 31, extends to the terminal block 2. Exemplarily, the high-voltage wire 6 includes a power supply line for power supply. During assembly, the high-voltage wire 6 is connected between the high-voltage wire connection part 31 and the terminal block 2. When the outdoor unit 100 of the air conditioner is installed and used, connecting the external power supply line to the terminal block 2 electrically connects the external power supply line to the power supply line included in the high-voltage wire 6, thereby supplying power to the outdoor unit 100. By providing the terminal block 2 to facilitate the connection of the wiring harness, the installation efficiency of the outdoor unit 100 of the air conditioner can be improved.

[0041] The phrase "the terminal block 2 is located at the side panel 12" can be interpreted broadly. For example, the terminal block 2 can be located inside the compressor cavity 100b and close to the side panel 12, or the terminal block 2 can be directly located on the side panel 12, which facilitates wiring at the terminal block 2.

[0042] The low-voltage wire 7 connected to the low-voltage wire connection part 32 does not need to be connected to the terminal block 2, thus facilitating the separate routing of the low-voltage wire 7 and the high-voltage wire 6.

[0043] The high-voltage wire connection part 31 and the low-voltage wire connection part 32 are respectively arranged in different areas of the circuit board 3, so that the high-voltage wire 6 connected by the high-voltage wire connection part 31 and the low-voltage wire 7 connected by the low-voltage wire connection part 32 can be further separated and routed, reducing the interference of the low-voltage signal by the high-voltage signal, reducing false alarm faults, improving the anti-interference capability of the circuit board 3, and improving the working reliability of the circuit board 3.

[0044] According to the embodiment of the present utility model, the outdoor unit 100 of the air conditioner has the strong wire connection part 31 and the weak wire connection part 32 respectively arranged in different areas of the circuit board 3, which facilitates the separate routing of the weak wire 7 and the strong wire 6, reduces the interference of strong electricity to weak electricity, improves the anti-interference ability of the circuit board 3, and enhances the working reliability of the outdoor unit 100 of the air conditioner.

[0045] In some embodiments of this utility model, such as Figure 1 As shown, the low-voltage wire connection portion 32 is positioned away from the terminal block 2 relative to the high-voltage wire connection portion 31. That is, the distance from the low-voltage wire connection portion 32 to the terminal block 2 is greater than the distance from the high-voltage wire connection portion 31 to the terminal block 2.

[0046] The high-voltage wire connection part 31 is located close to the terminal block 2. On the one hand, it can shorten the routing distance of the high-voltage wire 6. On the other hand, the extension of the high-voltage wire 6 occupies less space, and the low-voltage wire 7 can more easily avoid the extension path of the high-voltage wire 6, which is conducive to the separation of the low-voltage wire 7 and the high-voltage wire 6.

[0047] For example, the high-voltage wire connection portion 31 and the low-voltage wire connection portion 32 may be spaced apart in the vertical direction, and the terminal block 2 may be closer to the high-voltage wire connection portion 31 in the vertical height position; or, for example, the low-voltage wire connection portion 32 and the high-voltage wire connection portion 31 may be spaced apart in the horizontal direction, and the terminal block 2 may be positioned closer to the high-voltage wire connection portion 31 in the horizontal direction.

[0048] In some embodiments of this utility model, such as Figure 1 As shown, the circuit board 3 includes a first region 3a and a second region 3b. The first region 3a is higher than the second region 3b. The high-voltage wire connection part 31 is located in the first region 3a, and the low-voltage wire connection part 32 is located in the second region 3b.

[0049] The high-voltage wire connection part 31 is set higher than the low-voltage wire connection part 32. The high-voltage wire connection part 31 and the low-voltage wire connection part 32 are set vertically, which facilitates the separation of wiring. Compared with the high-voltage wire connection part and the low-voltage wire connection part being set horizontally, it can improve the close proximity of the low-voltage wire 7 and the high-voltage wire 6 caused by the compact left and right space, and also facilitates wiring operations.

[0050] Furthermore, it is understood that the low-voltage wire 7 connected to the low-voltage wire connection part 32 does not need to be connected to the terminal block 2. The low-voltage wire 7 can extend directly downwards, avoiding the high-voltage wire 6 while completing the connection with other low-voltage working devices. For example, a sensor is also provided in the compressor cavity 100b, located below the circuit board 3. When the low-voltage wire 7 connected to the low-voltage wire connection part 32 extends downwards to connect with the sensor, it can stay away from the high-voltage wire 6.

[0051] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the outdoor unit 100 of the air conditioner also includes a wire harness structure 4, which is located above the power line connection part 31 and is used to restrain the power line 6.

[0052] By setting up the wire harness structure 4, the routing of the high-voltage wire 6 can be constrained, reducing the possibility of the high-voltage wire 6 falling off or shaking and interfering with the low-voltage wire 7, and improving the neatness of the routing of the high-voltage wire 6.

[0053] The wire harness structure 4 is positioned above the high-voltage wire connection part 31. The high-voltage wire 6 extends upward from the high-voltage wire connection part 31 to the wire harness structure 4, thereby further separating the high-voltage wire 6 from the low-voltage wire 7 vertically.

[0054] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the terminal block 2 is lower than the wire harness structure 4.

[0055] The terminal block 2 is set below the wire harness structure 4. The high-voltage wire 6 extends upward to the wire harness structure 4 and then connects downward to the terminal block 2. The high-voltage wire 6 forms a bent section, which is conducive to the stable arrangement of the high-voltage wire 6 and can reduce the possibility of the high-voltage wire 6 falling off the wire harness structure 4.

[0056] Furthermore, since the terminal block 2 is positioned close to the high-voltage wire connection part 31 relative to the low-voltage wire connection part 32, the end of the high-voltage wire 6 connected to the terminal block 2 will not overlap with the low-voltage wire connection part 32 in the vertical direction, which facilitates the separate routing of the low-voltage wire 7 and the high-voltage wire 6.

[0057] The terminal block 2 is positioned below the wire harness structure 4, so the terminal block 2 does not need to be arranged above the circuit board 3. This reduces the space occupied by the terminal block 2 in the vertical direction, allowing the circuit board 3 to be positioned relatively higher in the compressor cavity 100b, saving space occupied in the compressor cavity 100b and facilitating its arrangement.

[0058] In some embodiments of this utility model, such as Figure 1 As shown, there are multiple high-voltage wire connection portions 31 arranged along the upper edge of the circuit board 3 and / or near the side edge of the side panel 12, and multiple low-voltage wire connection portions 32 arranged along the lower edge of the circuit board 3 and / or near the side edge of the side panel 12.

[0059] The high-voltage wire 6 has multiple connection points, and the multiple high-voltage wire connection points 31 are arranged along the upper edge of the circuit board 3 and / or near the side edge of the side panel 12. This can leave the middle area of ​​the circuit board 3 empty, which is convenient for the arrangement of electrical components on the circuit board 3 and can reduce interference with the electrical components on the circuit board 3.

[0060] The high-voltage wire connection part 31 is located near the side edge, which allows the high-voltage wire connection part 31 and the terminal block 2 to be close together. On the one hand, this can shorten the routing distance of the high-voltage wire 6, and on the other hand, the extension of the high-voltage wire 6 occupies less space, making it easier for the low-voltage wire 7 to avoid the extension path of the high-voltage wire 6, which is conducive to the separation of the low-voltage wire 7 from the high-voltage wire 6.

[0061] There are multiple low-voltage wire connection parts 32. The multiple low-voltage wire connection parts 32 are arranged along the lower edge of the circuit board 3 and / or near the side edge of the side panel 12, which can leave the middle area of ​​the circuit board 3 open, making it easier to arrange electrical components on the circuit board 3 and reducing interference to the electrical components on the circuit board 3.

[0062] For example, multiple high-voltage wire connection portions 31 are arranged along the upper edge of the circuit board 3, and multiple low-voltage wire connection portions 32 are arranged along the lower edge of the circuit board 3. The high-voltage wire connection portions 31 and low-voltage wire connection portions 32 are arranged vertically and vertically, and the vertical distance between the low-voltage wire connection portions 32 and the high-voltage wire connection portions 31 is relatively large, which helps to reduce the interference of the high-voltage wire 6 to the low-voltage wire 7.

[0063] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the circuit board 3 includes a third region 3c, which is located on the side of the first region 3a and the second region 3b near the fan cavity 100a. The third region 3c forms a heat dissipation duct 33. The outdoor unit 100 of the air conditioner includes a ventilation path 100c that connects the heat dissipation duct 33 and the fan cavity 100a. The circuit board 3 has components 34 and / or radiators disposed in the heat dissipation duct 33.

[0064] A ventilation path 100c connects the heat dissipation duct 33 and the fan cavity 100a. When the fan in the fan cavity 100a rotates, it draws the airflow in the heat dissipation duct 33 through the ventilation path 100c to the fan cavity 100a, thus creating a flowing airflow within the heat dissipation duct 33. The airflow from the heat dissipation duct 33 to the fan cavity 100a carries away the heat from the components 34 and / or heat sinks within the heat dissipation duct 33, achieving heat dissipation and improving the operational stability of the circuit board 3.

[0065] By setting a heat dissipation air duct 33 in the third region 3c, and setting the first region 3a and the second region 3b relatively far away from the third region 3c, the routing of the low-voltage wire 7 and the high-voltage wire 6 will not affect the heat dissipation of the components 34 and / or heat sink in the third region 3c, which is conducive to improving the heat dissipation efficiency of the circuit board 3 and improving the working reliability of the circuit board 3.

[0066] In some embodiments of this utility model, such as Figure 1 and Figure 3As shown, the components 34 set in the third region 3c may include capacitors 35 and inductors 36. The capacitors 35 and inductors 36 are relatively large. Both capacitors 35 and inductors 36 protrude relative to the circuit board 3 in the thickness direction of the circuit board 3. A relatively recessed ventilation space is formed between the capacitors 35 and inductors 36. All of these are within the heat dissipation air duct 33.

[0067] The components 34 disposed within the heat dissipation duct 33 may also include a first power device 341 and / or a heat sink disposed on the first power device 341. The first power device 341 generates a large amount of heat, and disposing of the first power device 341 within the heat dissipation duct 33 can improve the heat dissipation effect of the first power device 341.

[0068] The heat dissipation duct 33 can be part of the compressor cavity 100b, that is, the circuit board 3 has no outer casing and is directly exposed in the compressor cavity 100b; or, the circuit board 3 can also have an outer casing, the casing is located inside the compressor cavity 100b, and the heat dissipation duct 33b is defined by the casing and communicates with the compressor cavity 100b.

[0069] In some embodiments of this utility model, such as Figure 1 As shown, the outdoor unit 100 of the air conditioner includes a partition 8 separating the compressor chamber 100b and the fan chamber 100a. A vent 81 is formed on the partition 8 connecting the fan chamber 100a and the compressor chamber 100b, and the vent 81 is configured as a ventilation path 100c. Alternatively, the ventilation path 100c can also be a duct connecting the fan chamber 100a and the compressor chamber 100b, etc.

[0070] In some embodiments of this utility model, such as Figure 4 As shown, the circuit board 3 includes a first region 3a and a second region 3b. The second region 3b is located on the side of the first region 3a away from the side panel 12. The high-voltage wire connection part 31 is provided in the first region 3a, and the low-voltage wire connection part 32 is provided in the second region 3b.

[0071] The low-voltage wire connection part 32 and the high-voltage wire connection part 31 are arranged at intervals in the horizontal direction, and the terminal block 2 is arranged close to the high-voltage wire connection part 31 in the horizontal direction.

[0072] The high-voltage wire connection part 31 is positioned closer to the side panel 12 than the low-voltage wire connection part 32, horizontally separating the two parts for easier wiring separation. Furthermore, the proximity of the high-voltage wire connection part 31 to the side panel 12 allows for closer proximity between the high-voltage wire connection part 31 and the terminal block 2, thus shortening the wiring distance of the high-voltage wire 6.

[0073] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the outdoor unit 100 of the air conditioner also includes a wire harness structure 4, which is located on the side of the high power wire connection portion 31 away from the low power wire connection portion 32. The wire harness structure 4 is used to restrain the high power wire 6.

[0074] By setting the wire harness structure 4, the routing of the high-voltage wire 6 can be constrained, reducing the possibility of the high-voltage wire 6 falling off or shaking and interfering with the low-voltage wire 7, and improving the neatness of the high-voltage wire 6 routing. The wire harness structure 4 is located on the side of the high-voltage wire connection part 31 away from the low-voltage wire connection part 32. After the high-voltage wire 6 extends from the high-voltage wire connection part 31, it extends in a direction away from the low-voltage wire connection part 32 to the wire harness structure 4, thereby further separating the routing of the high-voltage wire 6 and the low-voltage wire 7.

[0075] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the outdoor unit 100 of the air conditioner also includes a housing 5, a circuit board 3 is mounted on the housing 5 and located on the side of the housing 5 near the front panel 11, and a wire harness structure 4 is located on the top of the housing 5 and above the circuit board 3.

[0076] The circuit board 3 is mounted on the housing 5, which provides support and improves the installation stability of the circuit board 3. Furthermore, the circuit board 3 is located on the side of the housing 5 closest to the panel, providing more space for operation during the assembly of the outdoor unit 100 of the air conditioner, thus facilitating the assembly efficiency of the outdoor unit 100 of the air conditioner.

[0077] The wire harness structure 4 is located on the top of the housing 5 and above the circuit board 3. The wire harness structure 4 is located on the outside of the housing 5 relative to the circuit board 3, which can reduce the interference of the high-voltage wire 6 to the components on the circuit board 3 when it is routed, and improve the working reliability of the circuit board 3.

[0078] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the low-voltage wire 7 and the high-voltage wire 6, which are connected to the low-voltage wire connection part 32, extend in opposite directions.

[0079] The low-voltage wire 7 and the high-voltage wire 6 extend in opposite directions, which more reliably reduces the interference of high voltage to low voltage.

[0080] In some embodiments of this utility model, such as Figure 3 and Figure 3 As shown, the terminal block 2 includes a terminal block 21 and terminal blocks 22. The terminal blocks 22 are disposed on the terminal block 21 and located on the side of the terminal block 21 near the outside of the side panel 12. The angle between the terminal block 21 and the circuit board 3 is greater than 30°. Here, "the angle between the terminal block 21 and the circuit board 3 is greater than 30°" refers to the angle between the terminal block 21 and the front surface of the circuit board 3 (e.g., the angle between the terminal block 21 and the front surface of the circuit board 3). Figure 3The included angle a1) marked in the figure is greater than 30°, and the included angle between the terminal block 21 and the rear surface of the circuit board 3 (e.g., the included angle a1) is greater than 30°. Figure 1 The included angle (a2) marked in the figure is also greater than 30°. Among them, "the outside of the side panel 12" refers to the side of the side panel 12 that is away from the compressor cavity 100b.

[0081] The terminal block 2 includes a terminal block 21 and terminal blocks 22. The terminal block 21 serves to install and support the terminal blocks 22, and the high-voltage wire 6 is connected to the terminal blocks 22. By placing the terminal blocks 22 on the outer side of the terminal block 21 near the side panel 12, with the terminal blocks 22 facing outwards, a larger operating space is available for wiring the terminal blocks 22, facilitating wiring and subsequent maintenance of the terminal block 2. In addition, the terminal block 21 has a large angle relative to the circuit board 3, and the terminal block 21 is positioned towards the side of the circuit board 3, which reduces interference between the terminal blocks 22 and the connected wires on the terminal block 21 and the electrical components on the front of the circuit board 3, thereby improving the operational reliability of the circuit board 3.

[0082] In some embodiments of this utility model, such as Figure 2 As shown, the terminal block 21 is set perpendicular to the circuit board 3.

[0083] The terminal block 22 is located on the side of the terminal block 21 away from the circuit board 3, which can reduce the interference of the terminal block 22 and the connected high-voltage wire 6 on the electrical components on the front of the circuit board 3, and improve the working reliability of the circuit board 3.

[0084] In some embodiments of this utility model, such as Figures 1-3 and ​ As shown, the junction box 21 is arranged parallel to the side panel 12.

[0085] The wiring terminal 22 is located on the side of the wiring board 21 away from the circuit board 3. The wiring terminal 22 is positioned facing the side panel 12, which facilitates wiring from near the side panel 12 and simplifies the wiring operation of the outdoor unit 100 of the air conditioner.

[0086] In some embodiments of this utility model, such as ​ As shown, the front side of the circuit board 3 faces the front panel 11, the terminal block 21 is perpendicular to the circuit board 3, and the terminal block 21 is parallel to the side panel 12.

[0087] The terminal block 22 is located on the side of the terminal block 21 away from the circuit board 3, which can reduce the interference of the terminal block 22 and the connected wire harness on the terminal block 21 to the electrical components on the front of the circuit board 3, and also facilitates wiring to the terminal block 2.

[0088] In some embodiments of this utility model, the front panel 11 is detachable or an openable first cover is provided at the corresponding circuit board 3; the side panel 12 is detachable or an openable second cover is provided at the corresponding terminal block 2.

[0089] The front panel 11 can be detachably connected, or an openable first cover can be provided on the front panel 11 corresponding to the circuit board 3, so that the front panel 11 can be opened and the space after opening is directly facing the circuit board 3, which facilitates the subsequent maintenance of the circuit board 3.

[0090] The side panel 12 can be detachably connected, or an openable second cover can be provided at the corresponding terminal block 2 on the side panel 12, so that the side panel 12 can be opened and the space after opening is directly opposite the terminal block 2, which facilitates the connection of the wiring harness and subsequent maintenance.

[0091] In some embodiments of this utility model, the terminal block 2 is disposed inside the compressor cavity 100b or on the side panel 12.

[0092] By placing the junction box 21 inside the compressor cavity 100b, the wiring harness connection can be protected inside the compressor cavity 100b, improving the neatness of the wiring and the operational reliability of the outdoor unit 100 of the air conditioner.

[0093] By placing the terminal block 21 on the side panel 12, the installation stability of the terminal block 21 can be improved, and it is convenient to connect the wires from near the side panel 12, making the wiring operation of the outdoor unit 100 of the air conditioner simple.

[0094] The air conditioning electronic control unit (ECU) draws power from the power grid, which is then converted to drive the compressor and fan, thus converting electricity into heat. It is the core component of a variable frequency air conditioner, and its stable operation is crucial for the normal functioning of the unit. To achieve accurate control, the ECU connects to other components, including not only high-voltage connections such as the power supply, fan, compressor, and four-way valve, but also low-voltage connections such as those for temperature, pressure, electronic expansion valves, and external communication. High-voltage signals are susceptible to external interference, while low-voltage signals are sensitive and easily affected. Therefore, proper handling of high-voltage and low-voltage wiring within the air conditioning system enhances its anti-interference capabilities and effectively improves its reliability.

[0095] To solve the above-mentioned technical problems, this application proposes an outdoor unit 100 for an air conditioner. The outdoor unit 100 for an air conditioner includes: a housing 1, a terminal block 2, and a circuit board 3. The housing 1 includes a front panel 11 and a side panel 12. The rear side of the front panel 11 has a fan cavity 100a and a compressor cavity 100b. The side panel 12 is located on the side of the compressor cavity 100b away from the fan cavity 100a.

[0096] Circuit board 3 is located inside compressor cavity 100b, facing the front panel 11 of housing 1, while terminal block 21 faces the side panel 12 of housing 1. The angle between circuit board 3 and terminal block 21 is greater than 30°. Circuit board 3 has a high-voltage wire connection part 31 and a low-voltage wire connection part 32 on the side facing the front panel 11. The high-voltage wire connection part 31 is located at the upper edge of circuit board 3, and the low-voltage wire connection part 32 is located at the lower edge of circuit board 3. Terminal block 21 is positioned close to the high-voltage wire connection part 31 on circuit board 3. The high-voltage wire 6 connected to the high-voltage wire connection part 31 is connected to terminal block 21, and the low-voltage wire 7 connected to the low-voltage wire connection part 32 exits from other locations on circuit board 3.

[0097] The outdoor unit 100 of the air conditioner also includes a wiring harness structure 4, which includes a wire clamping groove. The high-voltage wires 6 are bundled and fixed through the wire clamping groove before entering the circuit board 3, preventing the wire harness from shaking, being damaged, or short-circuiting inside the housing 1. This wiring method reduces interference between high-voltage and low-voltage circuits, reduces the risk of cable damage, effectively improves the anti-interference capability of the electrical control system, and enhances the reliability of the product.
