Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning technology, and in particular to a wiring structure and a photovoltaic air conditioner. Background Technology
[0002] In air conditioning technologies, photovoltaic (PV) air conditioners are typically used in areas with long hours of sunshine and open spaces. When PV is integrated, the air conditioner may not even need other power sources, relying solely on PV power, effectively saving mains electricity and making better use of environmental energy. In my country, the mains electricity is 220V AC, while PV power is DC. When sunlight is insufficient, both AC and DC power may be supplied simultaneously. In this situation, the AC mains wiring and the DC PV wiring inside the unit may interfere with each other due to the different magnetic fields after power-on. This can lead to signal distortion, decreased signal quality, and in severe cases, data transmission errors and control signal distortion. Long-term interference can cause overheating of internal circuits, component aging, chip damage, unstable operation, and even direct equipment damage. Utility Model Content

Simultaneously, designing routing surfaces in different directions reduces the crossing and tangling of wire bundles, ensuring orderly internal wiring of the photovoltaic air conditioner and facilitating assembly and maintenance.

[0041] In air conditioning technologies, photovoltaic (PV) air conditioners are typically used in areas with long hours of sunshine and open spaces. When PV is integrated, the air conditioner may not even need other power sources, relying solely on PV power, effectively saving mains electricity and making better use of environmental energy. In my country, the mains electricity is 220V AC, while PV power is DC. When sunlight is insufficient, both AC and DC power may be supplied simultaneously. In this situation, the AC mains wiring and the DC PV wiring inside the unit may interfere with each other due to the different magnetic fields after power-on. This can lead to signal distortion, decreased signal quality, and in severe cases, data transmission errors and control signal distortion. Long-term interference can cause overheating of internal circuits, component aging, chip damage, unstable operation, and even direct equipment damage.
[0042] Based on this, the following embodiments are proposed.
[0043] Example 1:
[0044] like Figure 1 , 2 As shown, a wiring structure component includes:
[0045] Multiple wiring components are spliced together in different settings to form a wiring surface with multiple different directions;
[0046] Multiple routing surfaces in different directions are used for routing different types of power supply lines.
[0047] Preferably, the routing of different types of power supply lines includes at least two of the following: photovoltaic routing, mains routing, low-voltage routing, grounding wire, and compressor routing.
[0048] In this embodiment, the application of wiring structure to photovoltaic air conditioning is used as an example for illustration:
[0049] When wiring components are installed inside a photovoltaic (PV) air conditioner, the wiring for different types of power supply lines is laid out on multiple wiring surfaces in different directions. These different directions reduce interference between the magnetic fields generated by PV wiring and mains wiring when energized. The magnetic field generated by PV wiring surrounds the direction of its current, and the magnetic field generated by mains wiring surrounds the direction of its current. With the surfaces containing PV and mains wiring intersecting, the overlap of their magnetic fields surrounding the current direction is largely avoided, effectively preventing interference between the magnetic fields after energization. Furthermore, designing wiring surfaces in different directions reduces tangling and cross-wiring between wires, ensuring orderly wiring within the PV air conditioner and facilitating assembly and maintenance.
[0050] The method of laying cables on the cable management board is to attach the cables to the corresponding cable management surface and secure them by binding them with fixing ropes or other fasteners through the holes on the cable management surface.
[0051] Optionally, in one implementation of this embodiment, such as Figure 1 , 2 As shown,
[0052] Multiple wiring components include a first wiring board 1 and a second wiring board 2. The first wiring board 1 is used to fix photovoltaic wiring, and the second wiring board 2 is used to fix mains power wiring. The first wiring board 1 and the second wiring board 2 are arranged intersecting each other.
[0053] In this embodiment, when the wiring structure is installed inside the photovoltaic air conditioner, the photovoltaic wiring of the photovoltaic air conditioner is laid on the first wiring board 1, and the mains power wiring of the photovoltaic air conditioner is laid on the second wiring board 2. By designing the first wiring board 1 and the second wiring board 2 to intersect, the surfaces where the photovoltaic wiring and the mains power wiring of the photovoltaic air conditioner are located are intersecting. This reduces the mutual interference of the magnetic fields generated by the photovoltaic wiring and the mains power wiring when energized. The magnetic field generated by the photovoltaic wiring after energization is around the direction of its current, and the magnetic field generated by the mains power wiring after energization is also around the direction of its current. With the surfaces where the photovoltaic wiring and the mains power wiring are located intersecting, the overlapping part of the magnetic fields around the direction of the current generated by the two is largely avoided, thereby effectively avoiding the mutual interference between the magnetic fields of the photovoltaic wiring and the mains power wiring after energization. At the same time, by designing the first wiring board 1 and the second wiring board 2 to intersect, the crossing and entanglement between the wire bundles are reduced, ensuring that the internal wiring of the photovoltaic air conditioner is orderly and convenient for assembly and maintenance.
[0054] In this embodiment, the first wiring board 1 and the second wiring board 2 are either assembled from two bent sheet metal pieces or directly bent from a single sheet metal piece. Together, they form a pre-assembled component, facilitating subsequent production and installation while significantly reducing magnetic field interference and wiring harness interference under complex wiring conditions, thus improving the overall reliability of the unit. The wiring structure in this embodiment provides mounting surfaces for both photovoltaic and mains power wiring within the extremely small internal space of the photovoltaic household air conditioner. It solves the crosstalk between AC mains power and DC photovoltaic power, and achieves a reasonable arrangement of unit wiring within a limited space. This simplifies the assembly process, improves production efficiency at a lower cost, and enhances the overall safety of the photovoltaic air conditioner.
[0055] Preferably, the first wiring board 1 has a staggered edge 20 at its edge. The staggered edge 20 is used to avoid high-profile components or other parts inside the photovoltaic air conditioner, while reducing the amount of sheet metal used.
[0056] Optionally, in one implementation of this embodiment, such as Figure 1-3 As shown,
[0057] The multiple wiring components also include: a third wiring board 3, which is used to fix the low-voltage wiring. The third wiring board 3 is intersected with the second wiring board 2 and intersected with the first wiring board 1.
[0058] In this embodiment, a third wiring board 3 is designed. When the wiring structure is installed inside the photovoltaic air conditioner, the low-voltage wiring of the photovoltaic air conditioner is laid on the third wiring board 3. The third wiring board 3 is close to the main control unit 13 of the photovoltaic air conditioner. The main control unit 13 of the photovoltaic air conditioner has a lot of low-voltage wiring. Setting the third wiring board 3 close to the main control unit 13 can facilitate the arrangement of some low-voltage wiring. Since the main control unit 13 itself also uses low-voltage wiring, setting it in the same area as the low-voltage wiring reduces the mutual interference between the main control unit 13 and the low-voltage wiring, further optimizing the internal layout of the photovoltaic air conditioner.
[0059] Optionally, in one implementation of this embodiment, such as Figure 1 , 2 As shown,
[0060] The multiple wiring components also include a fifth wiring board 10 and a photovoltaic support board 8, wherein the fifth wiring board 10 is used to fix the ground wire, and the photovoltaic support board 8 is used to fix the photovoltaic terminals of the photovoltaic air conditioner.
[0061] The first wiring board 1 has a first side 101 and a second side 102, the fifth wiring board 10 is connected to the first side 101, the fifth wiring board 10 has a third side 1010 and a fourth side 1011, the third side 1010 is closer to the second wiring board 2 than the fourth side 1011, and the photovoltaic support plate 8 is connected to the fourth side 1011.
[0062] In this embodiment, the fifth wiring board 10 is used to fix the ground wire of the photovoltaic air conditioner, and the photovoltaic support board 8 is used to install the photovoltaic terminals of the photovoltaic air conditioner. The photovoltaic terminals are placed horizontally on the photovoltaic support board 8, providing sufficient installation space for the photovoltaic terminals. At the same time, the photovoltaic support board 8 and the second wiring board 2 are designed to be spaced apart by the first wiring board 1 and the fifth wiring board 10, so that the photovoltaic terminals and the mains power lines are spaced apart by the first wiring board 1 and the fifth wiring board 10, further reducing electromagnetic cross-interference between the photovoltaic and the mains power.
[0063] Optionally, in one implementation of this embodiment, such as Figure 1-3 As shown,
[0064] Multiple wiring components also include:
[0065] The fourth wiring board 4 is used to fix the compressor wiring. The fourth wiring board 4 intersects with the second wiring board 2 and the third wiring board 3.
[0066] In this embodiment, the fourth wiring board 4 is used to fix the compressor wiring of the photovoltaic air conditioner. The fourth wiring board 4 is located inside the photovoltaic air conditioner and is close to the compressor 12. Since the compressor 12 has strong interference, its live power line can radiate a large amount of electromagnetic interference. Fixing the compressor wiring on the fourth wiring board 4 has the advantages of being close to the compressor 12 and convenient for wiring. In addition, by designing the fourth wiring board 4 to intersect with the second wiring board 2 and the third wiring board 3, the compressor wiring forms its own surface, which has little interference to other wiring, mains wiring and low voltage wiring. This effectively reduces the interference risk of strong interference lines inside the photovoltaic air conditioner and improves its overall reliability.
[0067] Optionally, in one implementation of this embodiment, such as Figure 1 , 2 As shown,
[0068] A first folded edge 5 is formed between the first wiring board 1 and the second wiring board 2, a second folded edge 6 is formed between the second wiring board 2 and the third wiring board 3, and a third folded edge 7 is formed between the third wiring board 3 and the fourth wiring board 4.
[0069] In this embodiment, the first wiring board 1 and the second wiring board 2, the second wiring board 2 and the third wiring board 3, and the third wiring board 3 and the fourth wiring board all have folded edge structures, so that the first wiring board 1, the second wiring board 2 and the third wiring board 3 are not on the same surface, thereby reducing electromagnetic interference between photovoltaic wiring, mains wiring and low voltage wiring. Each of its walls is a wiring component, which has a good shielding and reflection effect on the magnetic field generated after the wiring is energized, further reducing electromagnetic interference between the various wirings.
[0070] Preferably, the outer surfaces of the first fold 5, the second fold 6, and the third fold 7 are all arc-shaped surfaces.
[0071] The curved surface reduces the number of sharp edges on the outer edge of the wiring structure, minimizing edge scratches during assembly and enhancing the overall safety of the wiring structure.
[0072] Optionally, in one implementation of this embodiment, such as Figure 1 , 2 As shown,
[0073] The second side 102 is connected to the first support plate 19, and the fifth wiring plate 10 is connected to the second support plate 9 on the side away from the first side 101.
[0074] In this embodiment, the first support plate 19 and the second support plate 9 are provided to facilitate the fixing of the wiring structure inside the photovoltaic air conditioner. By fixing the first support plate 19 and the second support plate 9 to the plate inside the photovoltaic air conditioner, the wiring structure has two fixed points, which are relatively firm and can avoid the shaking of the wiring structure during transportation, which may affect the wiring inside the photovoltaic air conditioner or other components.
[0075] Optionally, in one implementation of this embodiment, such as Figure 1-3 As shown,
[0076] The plurality of wiring components also include a sixth wiring board 21, which is connected to the side of the fifth wiring board 10 away from the first edge 101.
[0077] In this embodiment, the sixth wiring board 21 is used to fix the low-voltage wiring near the four-way valve coil 15 and the pipe 16 inside the photovoltaic air conditioner. The sixth wiring board 21 can reduce the impact of vibration and high temperature caused by the operation of the four-way valve coil 15 and the pipe 16 on the surrounding low-voltage wiring.
[0078] Optionally, in one implementation of this embodiment, such as Figure 1 , 2 As shown,
[0079] The first wiring board 1, the second wiring board 2, and the third wiring board 3 are perpendicular to each other, and the fourth wiring board 4 is parallel to the first wiring board 1.
[0080] In this embodiment, the photovoltaic wiring, mains wiring, and low-voltage wiring in the photovoltaic air conditioner are arranged perpendicularly to each other using the first wiring board 1, the second wiring board 2, and the third wiring board 3. This reduces the mutual interference of the magnetic fields generated by the photovoltaic wiring, mains wiring, and low-voltage wiring when they are energized. The magnetic fields generated by the photovoltaic wiring, mains wiring, and low-voltage wiring after they are energized surround the direction of their current. With the three sides perpendicular to each other, the overlapping of the magnetic fields surrounding the direction of the current generated by the three is largely avoided, thereby effectively preventing mutual interference between the magnetic fields of the photovoltaic wiring, mains wiring, and low-voltage wiring after they are energized.
[0081] Meanwhile, by designing three perpendicular sides, the cross-tangling between wire harnesses is reduced, ensuring that the internal wiring harnesses of the photovoltaic air conditioner are orderly and easy to assemble and repair.
[0082] The first wiring board 1 and the fourth wiring board 4 are far apart and designed to be parallel. With minimal interference between the photovoltaic wiring and the compressor wiring, the wiring structure occupies less space. The wiring structure is a pre-assembled component, which facilitates subsequent production and installation, and greatly reduces magnetic field interference and wire harness interference under complex wiring conditions, thereby improving the overall reliability of the unit.
[0083] Optionally, in one implementation of this embodiment, such as Figure 1 , 2 As shown,
[0084] The first wiring board 1 and the second wiring board 2 are foldably connected together through the first folding edge 5, the second wiring board 2 and the third wiring board 3 are foldably connected together through the second folding edge 6, and the third wiring board 3 and the fourth wiring board 4 are foldably connected together through the third folding edge 7.
[0085] The angle between the first cable tray 1 and the second cable tray 2 can be adjusted according to the installation space of the cable tray structure, the angle between the second cable tray 2 and the third cable tray 3 can be adjusted according to the installation space of the cable tray structure, and the angle between the third cable tray 3 and the fourth cable tray 4 can be adjusted according to the installation space of the cable tray structure.
[0086] In this embodiment, the first wiring board 1 and the second wiring board 2, the second wiring board 2 and the third wiring board 3, and the third wiring board 3 and the fourth wiring board 4 are all designed to be foldable through corresponding folding edges, so that the angle between the wiring boards can be flexibly adjusted according to the installation space, further increasing the overall installation flexibility of the wiring structure.
[0087] Example 2
[0088] like Figure 3 As shown, a photovoltaic air conditioner is provided, including: the wiring structure component in Embodiment 1.
[0089] Specifically, the photovoltaic air conditioner includes: a housing 11, a compressor 12 installed inside the housing 11, a main control unit 13 and a mains power connection unit 14 installed inside the housing 11 and above the compressor 12; wherein, the third wiring board 3 faces the main control unit 13, the fourth wiring board 4 faces the compressor 12, and the mains power connection unit 14 is located on the fifth wiring board 10.
[0090] In this embodiment, when the wiring structure is installed inside the photovoltaic air conditioner, the low-voltage wiring of the photovoltaic air conditioner is laid on the third wiring board 3. The third wiring board 3 is close to the main control unit 13 of the photovoltaic air conditioner. The main control unit 13 of the photovoltaic air conditioner has a lot of low-voltage wiring. Setting the third wiring board 3 close to the main control unit 13 can facilitate the arrangement of some low-voltage wiring. Since the main control unit 13 itself also uses low-voltage wiring, setting it in the same area as the low-voltage wiring reduces the mutual interference between the main control unit 13 and the low-voltage wiring, further optimizing the internal layout of the photovoltaic air conditioner. The fourth wiring board 4 is located inside the photovoltaic air conditioner and is close to the compressor 12. Since the compressor 12 has strong interference, its power lines can radiate significant electromagnetic interference. Fixing the compressor wiring on the fourth wiring board 4 has the advantages of being close to the compressor 12 and facilitating wiring. Furthermore, by designing the fourth side to intersect with the second side and the third side, the compressor wiring becomes its own separate surface, minimizing interference with other wiring, mains wiring, and low-voltage wiring. This effectively reduces the potential interference from strong interference lines inside the photovoltaic air conditioner and improves its overall reliability.
[0091] Optionally, in one implementation of this embodiment, such as Figure 3 As shown,
[0092] The photovoltaic air conditioner includes a housing 11, and a partition 17 and a side panel 18 are provided inside the housing 11;
[0093] The first support plate 19 of the wiring structure is connected to the partition plate 17, and the second support plate 9 of the wiring structure is connected to the side plate 18.
[0094] In this embodiment, the first support plate 19 is fixedly connected to the partition plate 17, and the second support plate 9 is fixedly connected to the side plate 18, so that the wiring structure has two fixed points and is relatively firmly fixed, which can avoid the shaking of the wiring structure during transportation, which may affect the internal wiring of the photovoltaic air conditioner or other components.
[0095] Optionally, in one implementation of this embodiment, such as Figure 3 As shown,
[0096] The outer casing 11 also includes photovoltaic wiring, mains power wiring, low voltage wiring, ground wire, photovoltaic terminals, and compressor wiring;
[0097] The photovoltaic wiring is fixed on the first wiring plate 1 of the wiring structure component, the mains wiring is fixed on the second wiring plate 2 of the wiring structure component, the low voltage wiring is fixed on the third wiring plate 3 of the wiring structure component, the ground wire is fixed on the fifth wiring plate 10 of the wiring structure component, the photovoltaic terminal is fixed on the photovoltaic support plate 8 of the wiring structure component, and the compressor wiring is fixed on the fourth wiring plate 4 of the wiring structure component.
[0098] In this embodiment, the space in the overall photovoltaic air conditioner is extremely small. The wiring structure is located in a narrow space within the photovoltaic air conditioner, occupying little space. Through the design of the positions of each wall surface, the wiring structure can avoid interference as much as possible. At the same time, it can reduce electromagnetic interference between photovoltaic wiring, mains wiring, low-voltage wiring, compressor wiring and photovoltaic terminals. The wiring structure is made of multiple sheet metal pieces spliced together, or a single sheet metal piece is bent multiple times. Therefore, the wiring structure can be pre-assembled as a whole without multiple installations, which has the advantage of versatility and greatly improves assembly efficiency.
[0099] In summary, the ingenious design of the wiring structure lies in:
[0100] First, by routing different types of power supply lines across multiple routing surfaces in different directions, the interference between the magnetic fields generated by photovoltaic (PV) lines and mains lines when energized is reduced. The magnetic field generated by PV lines when energized surrounds the direction of their current, and the magnetic field generated by mains lines when energized also surrounds the direction of their current. With the routing surfaces intersecting, the overlap of the magnetic fields surrounding the current direction is largely avoided, effectively preventing mutual interference between the magnetic fields generated by PV and mains lines when energized. Simultaneously, designing routing surfaces in different directions reduces the crossing and tangling of wire bundles, ensuring orderly internal wiring of the photovoltaic air conditioner and facilitating assembly and maintenance.
[0101] Secondly, by designing the first and second wiring boards to intersect, the photovoltaic (PV) wiring and mains wiring of the photovoltaic air conditioner are positioned at intersections. This reduces the mutual interference of the magnetic fields generated by the PV and mains wiring when they are energized. The magnetic field generated by the energized PV wiring surrounds the direction of its current, and the magnetic field generated by the energized mains wiring also surrounds the direction of its current. The intersection of the PV and mains wiring surfaces largely avoids the overlap of the magnetic fields surrounding the current direction, thus effectively preventing mutual interference between the magnetic fields after the PV and mains wiring are energized. Simultaneously, the intersecting design of the first and second wiring boards reduces the crossing and tangling of wire bundles, ensuring orderly internal wiring of the photovoltaic air conditioner and facilitating assembly and maintenance.
[0102] Third, the first and second wiring boards are either assembled from two bent sheet metal pieces or directly bent from a single sheet metal piece. Together, they form a pre-assembled component, which facilitates subsequent production and installation while greatly reducing magnetic field interference and wiring harness interference under complex wiring conditions. This improves the overall reliability of the unit. The wiring structure provides mounting surfaces for both photovoltaic and mains power wiring within the extremely small internal space of the photovoltaic household air conditioner, solving the crosstalk between AC mains power and DC photovoltaic power. It also solves the problem of reasonable wiring arrangement within a limited space, simplifies the assembly process, improves production efficiency at a lower cost, and enhances the overall safety of the photovoltaic air conditioner.
[0103] Fourth, a third wiring board is designed to route the low-voltage wiring of the photovoltaic air conditioner. The third wiring board is located close to the main control unit of the photovoltaic air conditioner. The main control unit of the photovoltaic air conditioner has a lot of low-voltage wiring. By placing the third wiring board close to the main control unit, it is not only convenient to arrange some of the low-voltage wiring, but also because the main control unit itself uses low-voltage wiring, placing it in the same area as the low-voltage wiring reduces mutual interference between the main control unit and the low-voltage wiring, further optimizing the internal layout of the photovoltaic air conditioner.
[0104] Fifth, the photovoltaic terminals are placed horizontally on the photovoltaic support plate, providing ample installation space for the photovoltaic terminals. At the same time, the photovoltaic support plate and the second wiring plate are designed to be separated by the first wiring plate and the fifth wiring plate, so that the photovoltaic terminals and the mains power lines are separated by the first wiring plate and the fifth wiring plate, further reducing electromagnetic cross-interference between the photovoltaic and the mains power.
[0105] Sixth, the fourth wiring board is located inside the photovoltaic air conditioner and is close to the compressor. Since the compressor is highly interfering, its power lines can radiate significant electromagnetic interference. Fixing the compressor wiring to the fourth wiring board offers the advantages of proximity to the compressor and convenient wiring. Furthermore, by designing the fourth side to intersect with the second side and the third side, the compressor wiring becomes its own separate surface, minimizing interference with other wiring, mains wiring, and low-voltage wiring. This effectively reduces the potential interference from strong interference lines inside the photovoltaic air conditioner and improves its overall reliability.
[0106] Seventh, the design of the first wiring board 1, the second wiring board 2, and the third wiring board 3 is perpendicular to each other. This perpendicular arrangement of the photovoltaic (PV) wiring, mains wiring, and low-voltage wiring in the PV air conditioner reduces mutual interference of the magnetic fields generated by these wirings when energized. Since the magnetic fields generated by these wirings surround the direction of their current, the perpendicularity of the three sides largely avoids overlap of these magnetic fields, effectively preventing mutual interference. Furthermore, the perpendicular design reduces the crossing and tangling of wires, ensuring orderly wiring within the PV air conditioner and facilitating assembly and maintenance. The first and fourth wiring boards are far apart and designed to be parallel. With minimal interference between the photovoltaic wiring and the compressor wiring, the wiring structure occupies less space overall. The wiring structure is designed as a pre-assembled component, which facilitates subsequent production and installation while greatly reducing magnetic field interference and wiring harness interference under complex wiring conditions, thus improving the overall reliability of the unit.
