Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more particularly to an electrical control box and an air conditioner. Background Technology

[0002] In the structural design of the top-discharge outdoor air conditioner, the electrical control box is fixed by multiple points, and the electrical control box cannot be rotated.

[0003] Some electrical components are located on the back of the electrical control box, leaving no operating space when securing wiring harnesses, increasing the difficulty of operation. When core components on the back of the control box, such as refrigerant heat sinks or waterproof structures, require repair or replacement, the entire control box structure, related wiring harnesses, and refrigerant pipes must be completely removed before proceeding. This is not only time-consuming and labor-intensive but may also cause accidental damage to other related components during the operation, further expanding the scope of the fault. Moreover, the reassembly process after repair requires restoring all securing structures and wiring harness connections. Due to the large number of wiring harnesses and their similar interface types, incorrect terminal connections are highly likely during reconnection, which may not only lead to abnormal equipment function but, in severe cases, may cause circuit failures, short circuits, and other safety issues, posing a potential threat to the reliability and lifespan of the equipment.

[0004] To address the aforementioned issues, the applicant designed a rotatable electrical control box. When maintenance is required, the structure on the back of the control box can be accessed by rotating it to a certain angle. Based on this rotatable design, minimizing the impact of the control box rotation on related components is also a research direction for the applicant. Summary of the Invention

[0005] This invention provides an electrical control box and an air conditioner to solve the problem that the electrical control box is fixedly installed in the prior art, which makes it inconvenient to maintain the structure on the back of the electrical control box. The invention designs an electrical control box that can rotate relative to the air conditioner, which improves maintenance convenience. At the same time, a rotary structure is used to achieve linkage with the rotation of the electrical control box, which optimizes the performance of the first refrigerant heat dissipation pipe and the second refrigerant heat dissipation pipe.

[0006] This invention provides an electrical control box for use in an air conditioner, comprising: The electrical control box is rotatably mounted on the air conditioner and can rotate relative to the air conditioner about a rotation axis; A heat exchanger is installed on the electrical control box, and the heat exchanger is provided with a first refrigerant heat dissipation pipe and a second refrigerant heat dissipation pipe; A rotary structure, fixed to the air conditioner, includes a first rotary part and a second rotary part arranged concentrically; The first rotating part is provided with a first port and a second port that communicate with its interior. The first refrigerant heat dissipation pipe is connected to the first port, the second refrigerant heat dissipation pipe is connected to the second port, the first rotating part and the second rotating part communicate with each other internally, and the second rotating part is connected to the refrigerant pipe group of the air conditioner. When the electrical control box rotates around the rotating axis, the first rotating part rotates relative to the second rotating part around the central axis of the rotating structure.

[0007] According to an electrical control box provided by the present invention, the first refrigerant heat dissipation pipe and the second refrigerant heat dissipation pipe are both led out downward from the bottom of the electrical control box body, and the rotary structure is disposed below the electrical control box body; The central axis of the rotary structure is coaxial with or parallel to the rotation axis; The first rotating part has a first flow channel inside, and the second rotating part has a second flow channel inside. During the rotation of the electrical control box, the first flow channel and the second flow channel are connected.

[0008] According to an electrical control box provided by the present invention, the first rotating part is partially nested inside the second rotating part; The first flow channel includes a first channel extending axially along the first rotating part and a second channel disposed at one end of the first channel near the second rotating part, the second channel extending radially along the first rotating part and communicating with the first channel; The second flow channel includes a third channel extending circumferentially along the inner wall of the second rotating part and a fourth channel extending radially along the second rotating part in communication with the third channel.

[0009] According to an electrical control box provided by the present invention, the first port is connected to the first channel of one of the first flow channels; The first port is provided, and the first port is arranged axially along the first channel, or the first port is arranged radially along the first channel; Alternatively, the first port may have multiple ports; The second port is connected to the first channel of another first flow channel; The second port is provided, and the second port is arranged axially along the first channel, or the second port is arranged radially along the first channel; Alternatively, the second port may have multiple ports.

[0010] According to an electrical control box provided by the present invention, the second rotating part is provided with a third port and a fourth port for connecting the refrigerant pipe assembly of the air conditioner; The third port is connected to the fourth channel of one of the second flow channels; The third port is provided, and the third port is arranged axially along the fourth channel or radially along the fourth channel; Alternatively, multiple third ports may be provided; The fourth port is connected to the fourth channel of another second flow channel; The fourth port is provided, and the fourth port is arranged axially along the fourth channel or radially along the fourth channel; Alternatively, there may be multiple fourth ports.

[0011] According to an electrical control box provided by the present invention, the first refrigerant heat dissipation pipe and the second refrigerant heat dissipation pipe are disposed on the same plane as the first port and the second port; Alternatively, the plane containing the first port and the second port is located in front of or behind the plane containing the first refrigerant heat dissipation pipe and the second refrigerant heat dissipation pipe.

[0012] According to an electrical control box provided by the present invention, the first refrigerant heat dissipation pipe and the second refrigerant heat dissipation pipe are smoothly extended pipes or pipes with multiple bends and connections.

[0013] According to an electrical control box provided by the present invention, a seal and a bearing are provided between the first rotating part and the second rotating part.

[0014] According to an electrical control box provided by the present invention, the bottom of the electrical control box body is provided with a horizontally extending wiring partition that protrudes downward, and the high-voltage wire bundle and the low-voltage wire bundle inside the electrical control box body are respectively arranged on both sides of the wiring partition. Both the high-voltage wire harness and the low-voltage wire harness are arranged from the end of the wiring partition away from the rotating shaft to the end closer to the rotating shaft.

[0015] The present invention also provides an air conditioner, including the electrical control box as described above.

[0016] The electrical control box and air conditioner provided by this invention, by rotatably mounting the electrical control box on the air conditioner, allow for easy maintenance or replacement of the structure on the back of the box. Simply rotate the box to a convenient operating angle; complete removal of the box and disconnection of wiring harnesses and refrigerant pipes are unnecessary, significantly reducing operational difficulty and improving efficiency. Furthermore, eliminating the initial disassembly step prevents reinstallation after maintenance, avoiding incorrect wiring connections and ensuring normal machine operation. It is also understandable that for structures located on the rear of the air conditioner's electrical control box, rotating the box outwards by a certain angle facilitates maintenance of internal components and structures, providing operational convenience.

[0017] Furthermore, by connecting the first refrigerant heat dissipation pipe, the second refrigerant heat dissipation pipe, and the rotating structure to the refrigerant pipe assembly of the air conditioner, the refrigerant system on the air conditioner can be used to provide refrigerant for heat dissipation of the electrical control box, thereby achieving heat dissipation of the electrical control box without the need for an external refrigerant system. This simplifies the structural configuration and reduces costs. By setting up the rotating structure, when the electrical control box rotates around its axis, the first rotating part rotates relative to the second rotating part around the central axis of the rotating structure. This allows the first and second refrigerant heat dissipation pipes to rotate synchronously with the electrical control box without bending or twisting deformation. This greatly reduces the impact of the box rotation on the structure of the first and second refrigerant heat dissipation pipes, effectively preventing frequent deformation and cracking of the pipes that could lead to leakage, extending the service life of the pipes, and ensuring the safety and reliability of refrigerant circulation.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0022] In the description of this invention, it should be understood that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0025] like Figures 1 to 10 As shown, this invention provides an electrical control box for use in an air conditioner, comprising: an electrical control box body 10, which is rotatably mounted on an air conditioner 11 and can rotate relative to the air conditioner 11 about a rotation axis 12. The electrical control box body 10 is rotatably mounted; specifically, under normal circumstances, the box body remains fixed to the housing structure of the air conditioner 11, ensuring a certain degree of installation firmness. When it is necessary to repair or replace the structure on the back of the electrical control box body 10 (which can be the structure of the electrical control box body 10 itself or a structure on the unit body that is obscured by the electrical control box body 10), only the portion of the fixing structure between the electrical control box body 10 and the housing needs to be disassembled, and then the electrical control box body 10 can be rotated relative to the unit body by a certain angle. No further disassembly of structures is required, thus simplifying operation, increasing work efficiency, and avoiding adverse effects on surrounding structures. In this embodiment, the electrical control box body 10 can rotate relative to the air conditioner 11 about a vertical rotation axis 12.

[0026] A heat exchanger is mounted on the electrical control housing 10. The heat exchanger includes a first refrigerant heat dissipation pipe 13 and a second refrigerant heat dissipation pipe 14, both extending downwards from the bottom of the electrical control housing 10. Figure 1 As shown, the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are led out from the bottom of the electrical control box 10 and their lower ends are not blocked by the electrical control box 10. Therefore, even without rotating the electrical control box 10, the installation of the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 with the rotating structure 17 is not affected. The operating space is not blocked, which improves the convenience of operation.

[0027] A rotating structure 17 is fixed to the air conditioner. The rotating structure 17 includes a first rotating part 18 and a second rotating part 19 that are concentrically nested and capable of relative movement. The first rotating part 18 is provided with a first port 15 and a second port 16 for communicating with the internal flow channel of the first rotating part 18. The first refrigerant heat dissipation pipe 13 is connected to the first port 15, and the second refrigerant heat dissipation pipe 14 is connected to the second port 16. The first rotating part 18 and the second rotating part 19 are internally connected, and the second rotating part 19 is connected to the refrigerant pipe group of the air conditioner 11. When the electrical control box 10 rotates around the rotating shaft 12, the first rotating part 18 rotates relative to the second rotating part 19 around the central axis of the rotating structure 17.

[0028] By setting up the rotary structure 17, when the electrical control box 10 rotates around the rotating shaft 12, the first rotary part 18 rotates relative to the second rotary part 19 around the central axis of the rotary structure 17, so that the first refrigerant heat sink 13 and the second refrigerant heat sink 14 can rotate synchronously with the electrical control box 10 without bending or twisting. This greatly reduces the impact of the box rotation on the structure of the first refrigerant heat sink 13 and the second refrigerant heat sink 14, effectively preventing frequent deformation of the pipes from causing cracks and leakage, extending the service life of the pipes, and ensuring the safety and reliability of refrigerant circulation.

[0029] The first rotating part 18 and the second rotating part 19 are nested together. Either the first rotating part 18 is nested inside the second rotating part 19, or the second rotating part 19 is nested inside the first rotating part 18, depending on actual needs. The first rotating part 18 can rotate 360±N degrees relative to the second rotating part 19. The second rotating part 19 can be fixed to the housing of the air conditioner 11. The first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are connected to the interior of the first rotating part 18 through the first port 15 and the second port 16. The interior of the first rotating part 18 is connected to the interior of the second rotating part 19. The second rotating part 19 is also connected to the refrigerant pipe group of the air conditioner 11. This allows the air conditioner 11's refrigerant system to provide refrigerant for the electrical control box 10, achieving heat dissipation for the electrical control box 10 without the need for an external refrigerant system, simplifying the structural configuration and reducing costs. The central axis of the rotating structure 17 is coaxial or parallel to the rotation axis 12, ensuring smooth rotation of the electrical control box 10. The rotation axis 12 can be a virtual axis or a solid structure. When it is a solid structure, the central axis of the rotation axis 12 is set coaxially or parallel to the central axis of the rotary structure 17. Figure 1 The diagram illustrates the use of two hinges 20 to rotate the electrical control box 10, with the rotation axis 12 serving as the pivot of the hinges 20. However, the rotation axis 12 is not limited to the above structure; for example, it could be a relatively long pivot.

[0030] Since the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are not affected by rotation, preferably, the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are made of rigid pipe fittings, such as metal pipe fittings, which can further reduce the risk of refrigerant leakage, provide better pressure and temperature resistance, as well as anti-aging and anti-mechanical damage capabilities, and have a longer service life and stability; moreover, the inner wall of the rigid pipe is smooth and the pipe diameter is uniform, and the friction resistance and local resistance during fluid flow are smaller, which can reduce the pressure loss and energy loss of refrigerant during transportation and improve the operating efficiency of the air conditioning system; it is more suitable for long-distance or complex pipeline layouts and improves the layout flexibility in different installation space scenarios.

[0031] In a preferred embodiment of the present invention, the first rotating part 18 is provided with a first flow channel 21, and the second rotating part 19 is provided with a second flow channel 22. During the rotation of the electrical control box 10, the first flow channel 21 and the second flow channel 22 are connected.

[0032] By ensuring the continuous connection between the first flow channel 21 and the second flow channel 22 during the rotation of the electrical control box 10, the normal flow of refrigerant is guaranteed. This ensures the continuity and stability of refrigerant circulation, maintains the air conditioning's cooling / heating performance, keeps system parameters normal, protects components such as pipes and compressors, extends their service life, reduces malfunctions, and avoids safety hazards and environmental risks caused by refrigerant leaks. In other words, the rotation of the electrical control box 10 does not affect the refrigerant circulation, ensuring the operational reliability of the air conditioning system.

[0033] For ease of description, the rotary structure 17 in the following embodiment adopts a first rotary part 18 nested inside the second rotary part 19 to realize the installation of the first rotary part 18 and the second rotary part 19 and the connection of the internal flow channels.

[0034] In some embodiments, the first flow channel 21 includes a first channel 211 extending axially along the first rotating portion 18 and a second channel 212 disposed at one end of the first channel 211 near the second rotating portion 19, the second channel 212 extending radially along the first rotating portion 18 and communicating with the first channel 211; Figure 3 As shown, there are two first flow channels 21 to enable the refrigerant to flow in opposite directions, thus achieving refrigerant circulation between the electrical control box 10 and the air conditioner 11. The first channels 211 of the two first flow channels 21 have different lengths so that they can be connected to the corresponding second flow channels 22 of the second rotating part 19 through second channels 212 at different axial positions.

[0035] The second flow channel 22 includes a third channel 221 extending circumferentially along the inner wall of the second rotating part 19 and a fourth channel 222 extending radially along the second rotating part 19 and communicating with the third channel 221. Two second flow channels 22 are provided to allow the refrigerant to flow in opposite directions, thus achieving refrigerant circulation between the electrical control box 10 and the air conditioner 11. The two second flow channels 22 are located at different positions along the axial direction of the second rotating part 19. Figure 4 The direction of the middle arrow indicates the flow direction of the refrigerant, including the refrigerant path flowing from the air conditioner 11 to the electrical control box 10 and the refrigerant path flowing back from the electrical control box 10 to the air conditioner 11.

[0036] Among them, the third channel 221 is an annular channel. In specific applications, no matter how the first rotating part 18 rotates, the second channel 212 can be connected to the annular third channel 221, so that the refrigerant flows through the second channel 212 to the third channel 221, then to the fourth channel 222, and then to the relevant pipes of the air conditioner 11. The principle of the reverse flow path is the same, and will not be described again.

[0037] Furthermore, the first port 15 and the second port 16 are transition structures that enable the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 to connect with the first channel 211. Similar to a connector, by optimizing the setting position / opening orientation and number of the first port 15 and the second port 16, it is helpful to adapt to the installation of the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 with different spatial arrangements, or to improve the refrigerant delivery efficiency and thus improve the heat dissipation effect.

[0038] In some embodiments, the first port 15 is connected to the first channel 211 of one of the first flow channels 21, and one or more first ports 15 may be provided.

[0039] When one first port 15 is provided, the first port 15 is arranged axially along the first channel 211, or the first port 15 is arranged radially along the first channel 211; for example... Figure 4 As shown, "the first port 15 is axially arranged along the first channel 211" means that the first port 15 is axially open along the first channel 211, and "the first port 15 is radially arranged along the first channel 211" means that the first port 15 is radially open along the first channel 211. It can be understood that when the first port 15 is radially arranged along the first channel 211, it can be arranged in any direction along the peripheral sidewall of the first rotating part 18.

[0040] The first port 15 can also be configured with multiple ports, such as... Figure 4 Two first ports 15 are provided, one first port 15 is axially arranged along the first channel 211, and the other first port 15 is radially arranged along the first channel 211.

[0041] When multiple first ports 15 are provided, only one first port 15 can be used to connect the pipeline, and the other first ports 15 can be sealed when not in use, such as by sealing plugs. Alternatively, multiple first ports 15 can be connected to multiple pipelines respectively, thereby providing multiple refrigerant flows and improving heat exchange efficiency.

[0042] The second port 16 is connected to the first channel 211 of another first flow channel 21, and one or more second ports 16 may be provided.

[0043] When a second port 16 is provided, the second port 16 is arranged axially along the first channel 211, or the second port 16 is arranged radially along the first channel 211; for example... Figure 4 As shown, "the second port 16 is axially arranged along the first channel 211" means that the second port 16 is axially open along the first channel 211, and "the second port 16 is radially arranged along the first channel 211" means that the second port 16 is radially open along the first channel 211. It can be understood that when the second port 16 is radially arranged along the first channel 211, it can be arranged in any direction along the peripheral sidewall of the first rotating part 18.

[0044] The second port 16 can also be configured with multiple ports, such as... Figure 4 Two second ports 16 are provided, one second port 16 is axially arranged along the first channel 211, and the other second port 16 is radially arranged along the first channel 211.

[0045] When multiple second ports 16 are provided, only one second port 16 can be used to connect the pipeline, and the other second ports 16 can be sealed when not in use, such as by sealing plugs. Alternatively, multiple second ports 16 can be connected to multiple pipelines respectively, thereby providing multiple refrigerant flows and improving heat exchange efficiency.

[0046] Furthermore, in order to connect the second rotating part 19 to the refrigerant piping assembly of the air conditioner 11, in some embodiments, such as Figure 1 As shown, the second rotating part 19 is provided with a third port 23 and a fourth port 24 for connecting the refrigerant pipe assembly of the air conditioner 11. Specifically, one of the third port 23 and the fourth port 24 is connected to the liquid collection pipe assembly 25 (including the electronic expansion valve pipe assembly) of the air conditioner 11, and the other of the third port 23 and the fourth port 24 is connected to the plate heat exchanger pipe assembly 26 of the air conditioner 11.

[0047] Among them, the third port 23 and the fourth port 24 are the transition structures that enable the fourth channel 222 to connect with the refrigerant pipe group of the air conditioner 11. They are similar to connectors. By optimizing the setting position / opening orientation and number of the third port 23 and the fourth port 24, it is helpful to adapt to the installation of refrigerant pipe groups with different spatial arrangements, or to improve the refrigerant delivery efficiency and thus improve the heat dissipation effect.

[0048] The third port 23 is connected to the fourth channel 222 of one of the second channels 22, and one or more third ports 23 may be provided.

[0049] When one third port 23 is provided, the third port 23 is arranged axially along the fourth channel 222, or the third port 23 is arranged radially along the fourth channel 222; for example... Figure 4 As shown, "the third port 23 is axially arranged along the fourth channel 222" means that the third port 23 is axially open along the fourth channel 222, and "the third port 23 is radially arranged along the fourth channel 222" means that the third port 23 is radially open along the fourth channel 222. It can be understood that when the third port 23 is radially arranged along the fourth channel 222, it can be arranged in any direction along the peripheral sidewall of the second rotating part 19.

[0050] Multiple third ports 23 can also be configured, such as... Figure 4 To provide three third ports 23, one third port 23 is axially arranged along the fourth channel 222, and the other two third ports 23 are radially arranged along the fourth channel 222.

[0051] When multiple third ports 23 are installed, only one third port 23 can be used to connect the pipeline, and the other third ports 23 can be sealed when not in use, such as by sealing plugs. Alternatively, multiple third ports 23 can be connected to multiple pipelines respectively, thereby providing multiple refrigerant flows and improving heat exchange efficiency.

[0052] The fourth port 24 is connected to the fourth channel 222 of another second flow channel 22. One or more fourth ports 24 may be provided, and they may be provided axially and / or radially along the fourth channel 222. For details, refer to the setting method of the third port 23 described above, which will not be repeated here.

[0053] Based on the above embodiments, according to the electrical control box provided by the present invention, the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 may have different positional relationships with the first port 15 and the second port 16. For example, in a first example, such as Figure 5 and Figure 6As shown, the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are arranged on the same plane as the first port 15 and the second port 16. In this way, the central axis of the rotating structure 17 is coaxial with the rotation axis 12, which helps to reduce the length of the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14, making the overall structure layout more compact.

[0054] In the second example, such as Figures 7 to 10 As shown, the plane containing the first port 15 and the second port 16 is located in front of or behind the plane containing the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14. "Front" refers to the side facing the front of the electrical control box 10, and "rear" refers to the side facing the back of the electrical control box 10. In this configuration, the central axis of the rotating structure 17 is not on the same plane as the rotation axis 12 but is parallel to it. This makes the installation of the rotating structure 17 more flexible, and allows for various spatial arrangements of the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14.

[0055] Furthermore, the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 can take various shapes, such as Figure 5 and Figure 7 In the design, the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are L-shaped pipes, and the overall pipe fittings have a smooth, extended structure, which facilitates processing. For example... Figure 9 As shown, the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are irregularly shaped pipes with a multi-segment bending connection structure, increasing the diversity of pipe shapes. It can be understood that regardless of whether the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are on the same plane or different planes from the first port 15 and the second port 16, the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 can adopt L-shaped, irregular, or a combination of L-shaped and irregular shapes, which can be set according to actual needs.

[0056] Based on the above embodiments, in order to achieve relative rotation between the first rotating part 18 and the second rotating part 19, a seal and a bearing 27 are provided between the first rotating part 18 and the second rotating part 19, such as... Figure 3 As shown, in this embodiment, the first rotating part 18 is nested inside the second rotating part 19. Bearings 27 and sealing rings 28 are provided at both ends of the mating area between the first rotating part 18 and the second rotating part 19, and a bearing end cap 29 is also provided at the open end of the second rotating part 19. To further improve the structural sealing and prevent leakage, multiple sealing rings 28 are spaced apart in the mating area between the first rotating part 18 and the second rotating part 19 to ensure reliable sealing.

[0057] Based on the above embodiments, according to the present invention, an electrical control box is provided, wherein the bottom of the electrical control box body 10 is provided with a horizontally extending cable tray 30 protruding downwards, and the high-voltage cable bundle 31 and the low-voltage cable bundle 32 inside the electrical control box body 10 are respectively arranged on both sides of the cable tray 30. By separating the high-voltage cable bundle 31 and the low-voltage cable bundle 32, the safety of use can be improved.

[0058] like Figure 2 As shown, both the high-voltage wire harness 31 and the low-voltage wire harness 32 are arranged from the end of the wiring partition 30 away from the rotating shaft 12 towards the end closer to the rotating shaft 12. Specifically, the high-voltage wire harness 31, for example, runs from the lower front of the wiring partition 30, arranged from right to left and fixed at approximately 300mm intervals. After reaching the left side, it is led out downwards through a pre-reserved slot on the wiring partition 30 and then distributed to the entire machine. The low-voltage wire harness 32 runs from the upper back of the wiring partition 30, arranged from right to left and fixed at approximately 300mm intervals. After reaching the left side, it is led out through a pre-reserved slot on the wiring partition 30 and then distributed to the entire machine. In the scenario where the electrical control box 10 rotates left and right around the rotating shaft 12, both the high-voltage wire harness 31 and the low-voltage wire harness 32 are routed to the left side of the box near the rotating shaft 12, which helps to reduce the reserved length of the wire harness and ensures smooth rotation of the electrical control box 10.

[0059] The present invention also provides an air conditioner 11, which includes the electrical control box of the above embodiments and examples, and has all the structure and all the beneficial effects of the above electrical control box, which will not be repeated here.

[0060] The electrical control box and air conditioner 11 provided by this invention, by rotatably mounting the electrical control box 10 onto the air conditioner 11, allow for easy maintenance or replacement of the structure on the back of the electrical control box 10. Only the electrical control box 10 needs to be rotated to a convenient operating angle, eliminating the need to completely remove the electrical control box 10 or disassemble related wiring harnesses and refrigerant pipes. This significantly reduces operational difficulty and improves efficiency. Furthermore, since the initial disassembly step is eliminated, reinstallation is not required after maintenance, preventing incorrect wiring connections and ensuring normal machine operation. It is also understood that for structures mounted on the air conditioner 11 at the rear of the electrical control box 10, rotating the electrical control box 10 outwards by a certain angle facilitates maintenance of internal components or structures, providing operational convenience.

[0061] Furthermore, by connecting the first refrigerant heat dissipation pipe 13, the second refrigerant heat dissipation pipe 14, and the rotating structure 17 to the refrigerant pipe assembly of the air conditioner 11, the refrigerant system on the air conditioner 11 can be used to provide refrigerant for heat dissipation of the electrical control box 10, thereby achieving heat dissipation of the electrical control box 10 without the need for an external refrigerant system, which helps to simplify the structural configuration and reduce costs. By setting the rotating structure 17, when the electrical control box 10 rotates around the rotating axis 12, the first rotating part 18 rotates relative to the second rotating part 19 around the central axis of the rotating structure 17, so that the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 can rotate synchronously with the electrical control box 10 without bending or twisting deformation. This greatly reduces the impact of the box rotation on the structure of the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14, effectively preventing frequent deformation of the pipes and cracking that could cause leakage, extending the service life of the pipes, and ensuring the safety and reliability of refrigerant circulation.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
