When the core components on the back of the electric control box body, such as the refrigerant heat dissipation plate and the waterproof structure, need to be repaired or replaced, the overall structure of the electric control box body, the related wire harness and the refrigerant pipe need to be completely removed, which not only consumes time and effort, but also may cause accidental damage to other related components during the operation process, further expanding the fault range, and the reinstallation process after the repair is completed needs to restore all fixed structures and wire harness connections. Due to the large number of wire harnesses and similar interface types, it is easy to connect the wrong terminals during the reconnection process, which not only may cause abnormal device function, but also may cause circuit failure, short circuit and other safety problems, which poses a potential threat to the operation reliability and service life of the device.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

In the description of the specification, the description of the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0025] As shown in Figures 1 to 15 The present application provides an electric control box applied to an air conditioner 11, comprising: an electric control box body 10 rotatably arranged on the air conditioner 11, the electric control box body 10 being provided with a heat exchanger, the heat exchanger being provided with a first refrigerant heat dissipation pipe 13 and a second refrigerant heat dissipation pipe 14; A rotating assembly comprising a first rotating member 15 and a second rotating member 16, the first rotating member 15 and the second rotating member 16 being fixedly arranged on the air conditioner 11 with a spacing therebetween; The first rotating member 15 comprises a first rotating part 17 and a second rotating part 18 connected in communication, the first rotating part 17 being connected with the first refrigerant heat dissipation pipe 13, and the second rotating part 18 being connected with a refrigerant pipeline of the air conditioner 11; The second rotating member 16 comprises a third rotating part 19 and a fourth rotating part 20 connected in communication, the third rotating part 19 being connected with the second refrigerant heat dissipation pipe 14, and the fourth rotating part 20 being connected with the refrigerant pipeline of the air conditioner 11; When the electric control box body 10 rotates, the first rotating part 17 rotates relative to the second rotating part 18, and the third rotating part 19 rotates relative to the fourth rotating part 20.

[0026] Specifically, the electric control box 10 is rotatably installed. Specifically, under normal circumstances, the box is still fixed on the shell structure of the air conditioner 11 to ensure a certain installation firmness. When the structure on the back of the electric control box 10 (which can be the structure of the electric control box 10 itself or the structure of the machine body blocked by the electric control box 10) needs to be repaired or replaced, only the partial fixing structure between the electric control box 10 and the shell needs to be disassembled, and then the electric control box 10 is rotated relative to the machine body by a certain angle, without the need to disassemble more structures, thus being simple to operate, high in work efficiency, and capable of avoiding adverse effects on the surrounding structures. In the present embodiment, the electric control box 10 can be rotated left and right relative to the air conditioner 11 about a vertical rotation shaft 12.

[0027] As shown in Figure 1 the first and second refrigerant heat dissipation pipes 13 and 14 are led downward from the bottom of the electric control box 10, and the lower end portions thereof are not blocked by the electric control box 10. Thus, even without rotating the electric control box 10, the installation of the first and second refrigerant heat dissipation pipes 13 and 14 relative to the rotary assembly is not affected, the operation space is not blocked, and the operation convenience is improved.

[0028] By providing the rotary assembly, when the electric control box 10 is rotated relative to the air conditioner 11, the first rotary part 17 is rotated relative to the second rotary part 18, and the third rotary part 19 is rotated relative to the fourth rotary part 20, so that the first and second refrigerant heat dissipation pipes 13 and 14 can be synchronously rotated with the electric control box 10 without being bent or twisted and deformed, greatly reducing the influence of the rotation of the box on the structure of the first and second refrigerant heat dissipation pipes 13 and 14, effectively preventing the pipes from being frequently deformed and cracked to cause liquid leakage, prolonging the service life of the pipes, and ensuring the safety and reliability of the circulation of the refrigerant. The first and second refrigerant heat dissipation pipes 13 and 14 are connected by two rotary parts, respectively, which is conducive to reducing the volume of a single rotary part, making the single rotary part simple in structure and easy to process, and reducing the failure rate of the rotary part to ensure the flow effect of the refrigerant between the electric control box 10 and the air conditioner 11.

[0029] The first and second rotary parts 17 and 18 are nested, which can be that the first rotary part 17 is nested in the interior of the second rotary part 18, or that the second rotary part 18 is nested in the interior of the first rotary part 17, according to actual requirements. Figure 1As shown, in the embodiment, the first rotating part 17 is arranged above the second rotating part 18, and the second rotating part 18 is fixed to the air conditioner 11 through the support 27. In other embodiments, the first rotating part 17 can also be arranged below the second rotating part 18. The first rotating part 17 can rotate 360±N degrees relative to the second rotating part 18, ensuring the follow-up characteristics of the first refrigerant heat dissipation pipe 13 when the electric control box 10 rotates. The third rotating part 19 and the fourth rotating part 20 are nested, which can be that the third rotating part 19 is nested inside the fourth rotating part 20, or the fourth rotating part 20 is nested inside the third rotating part 19, arranged according to actual needs. The relative position relationship of the third rotating part 19 and the fourth rotating part 20 is also arranged according to actual needs, such as Figure 1 As shown, in the embodiment, the third rotating part 19 is arranged above the fourth rotating part 20, and the fourth rotating part 20 is fixed to the air conditioner 11 through the support 27. In other embodiments, the third rotating part 19 can also be arranged below the fourth rotating part 20. The third rotating part 19 can rotate 360±N degrees relative to the fourth rotating part 20, ensuring the follow-up characteristics of the first refrigerant heat dissipation pipe 13 when the electric control box 10 rotates.

[0030] The electric control box 10 can rotate left and right relative to the air conditioner 11 around a rotating shaft 12, which can be a virtual axis or a physical structure. Figure 1 It is shown that two hinges 21 are used to realize the rotation of the electric control box 10, and the rotating shaft 12 is the rotating shaft of the hinge 21. Of course, the rotating shaft 12 is not limited to the above structure, for example, it can also be a relatively long rotating shaft.

[0031] The rotating assembly is arranged on one side of the rotating shaft 12, and the center axis of the first rotating part 15 is coaxial or parallel with the rotating shaft 12, and the center axis of the second rotating part 16 is coaxial or parallel with the rotating shaft 12. That is, the first rotating part 15 and the second rotating part 16 are arranged at appropriate positions according to the spatial position of the rotating shaft 12, to ensure the smoothness of the rotation of the electric control box 10.

[0032] 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 adopt hard pipe fittings, such as metal pipe fittings, which can further reduce the risk of refrigerant leakage, provide more excellent pressure and temperature resistance, and have better anti-aging and anti-mechanical damage capabilities, with longer service life and stability. Moreover, the inner wall of the hard pipe is smooth and the pipe diameter is uniform, so that the flow resistance and local resistance of the fluid are smaller, which can reduce the pressure loss and energy loss of the refrigerant in the conveying process and improve the operating efficiency of the air conditioning system. It is more suitable for long-distance or complex pipe layout, and improves the flexibility of arrangement in different installation space scenarios.

[0033] As a preferred embodiment of the present application, the first rotary part 17 and the second rotary part 18 remain in communication, and the third rotary part 19 and the fourth rotary part 20 remain in communication during rotation of the electric control box 10.

[0034] By keeping the first rotary part 17 and the second rotary part 18 in communication, and the third rotary part 19 and the fourth rotary part 20 in communication at all times during rotation of the electric control box 10, the normal circulation of the refrigerant is ensured, the continuity and stability of the refrigerant circulation are guaranteed, the refrigeration / heating effect of the air conditioner is not affected, the system parameters are maintained normal, the components such as the pipeline and the compressor are protected, the service life is prolonged, the failure is reduced, and the safety hazard and environmental risk caused by refrigerant leakage are avoided. That is, the rotation of the electric control box 10 does not affect the circulation of the refrigerant, and the operation reliability of the air conditioning system is ensured.

[0035] In some embodiments, the first rotary part 17 is sleeved on the inside of the second rotary part 18, the first rotary part 17 is provided with a first channel 171 extending in the axial direction thereof, the second rotary part 18 is provided with a second channel 181 extending in the axial direction thereof, and one end of the second channel 181 is in communication with the first channel 171. As shown in Figure 2 The first channel 171 and the second channel 181 adopt an axial communication channel structure, which greatly simplifies the internal flow passage design of the first rotary part 15 and reduces the machining cost of the first rotary part 15. The first channel 171 adopts an axial through design, and in specific applications, no matter how the first rotary part 17 rotates, the first channel 171 can be ensured to be in communication with the second channel 181, thereby ensuring the normal flow of the refrigerant.

[0036] The third rotary part 19 is sleeved on the inside of the fourth rotary part 20, the third rotary part 19 is provided with a third channel extending in the axial direction thereof, the fourth rotary part 20 is provided with a fourth channel extending in the axial direction thereof, and one end of the fourth channel is in communication with the third channel. The cooperation relationship between the third rotary part 19 and the fourth rotary part 20 can refer to the cooperation relationship between the first rotary part 17 and the second rotary part 18 described above, and will not be repeated here.

[0037] Further, the first rotary part 17 is provided with a first port 172 in communication with the first channel 171, which is used to connect the first refrigerant heat dissipation pipe 13. By optimizing the setting position / opening direction and the number of the first port 172, it is helpful to adapt the installation of the first refrigerant heat dissipation pipe 13 with different space layouts, or to improve the refrigerant conveying efficiency and thus improve the heat dissipation effect.

[0038] In one example, the first port 172 is provided with one, which is arranged axially along the first channel 171 or radially along the first channel 171. The first port 172 arranged axially along the first channel 171 means that the first port 172 is arranged to open in the axial direction of the first channel 171, and the first port 172 arranged radially along the first channel 171 means that the first port 172 is arranged to open in the radial direction of the first channel 171. It can be understood that when the first port 172 is arranged radially along the first channel 171, the first port 172 can be arranged to face any direction along the circumferential wall of the first rotating part 17.

[0039] In another example, the first port 172 is provided with multiple; for example, Figure 3 In order to provide two first ports 172, one first port 172 is arranged axially along the first channel 171, and the other first port 172 is arranged radially along the first channel 171.

[0040] When multiple first ports 172 are provided, only one of the first ports 172 can be used for connecting the pipeline, and the other first ports 172 are not used and are plugged, for example, by a sealing plug. Alternatively, multiple first ports 172 can be connected to multiple pipelines respectively, thereby providing multiple paths for the flow of refrigerant and improving the heat exchange efficiency.

[0041] The third rotating part 19 is provided with a third port in communication with the third channel, which is used to connect the second refrigerant heat dissipation pipe 14. The third port is provided with one, which is arranged axially along the third channel or radially along the third channel, or the third port is provided with multiple. The arrangement of the third port can refer to the above-mentioned first port 172, which will not be described here again.

[0042] Further, the second rotating part 18 is provided with a second port 182 in communication with the second channel 181, which is used to connect the refrigerant pipeline of the air conditioner 11. By optimizing the arrangement position / opening direction and number of the second port 182, it is helpful to adapt to the installation of the refrigerant pipeline of the air conditioner 11 with different space layouts, or to improve the refrigerant delivery efficiency and thus improve the heat dissipation effect.

[0043] In one example, the second port 182 is provided with one, which is arranged axially along the second channel 181 or radially along the second channel 181. The second port 182 arranged axially along the second channel 181 means that the second port 182 is arranged to open in the axial direction of the second channel 181, and the second port 182 arranged radially along the second channel 181 means that the second port 182 is arranged to open in the radial direction of the second channel 181. It can be understood that when the second port 182 is arranged radially along the second channel 181, the second port 182 can be arranged to face any direction along the circumferential wall of the second rotating part 18.

[0044] In another example, the second port 182 is provided with multiple second ports; as Figure 3 To provide two second ports 182, one second port 182 is arranged axially along the second channel 181, and the other second port 182 is arranged radially along the second channel 181. When multiple second ports 182 are provided, only one second port 182 can be used for connecting the pipeline, and the other second ports 182 are not used and are plugged, such as by a sealing plug. Alternatively, multiple second ports 182 can be connected to multiple pipelines respectively, thereby providing multiple paths for the flow of refrigerant and improving the heat exchange efficiency.

[0045] The fourth rotating part 20 is provided with a fourth port in communication with the fourth channel, for connecting the refrigerant pipeline of the air conditioner 11, the fourth port is provided with one, the fourth port is arranged axially along the fourth channel, or the fourth port is arranged radially along the fourth channel, or the fourth port is provided with multiple. The arrangement of the fourth port can refer to the above-mentioned second port 182, which will not be described here.

[0046] Among them, one of the second port 182 and the fourth port connects the liquid collecting pipeline 22 of the air conditioner 11, of course, it is not limited to the liquid collecting pipeline 22, but also can be connected to the refrigerant from any branch of the whole machine pipeline, the other of the second port 182 and the fourth port connects the plate heat exchanger pipeline 23 of the air conditioner 11, of course, it is not limited to the plate heat exchanger pipeline 23, but also can be connected to the refrigerant from any branch of the whole machine pipeline.

[0047] The above-mentioned related pipeline and the corresponding port can be welded at 180 degrees, or welded at 90 degrees, or welded at any angle in space, increasing the flexibility of pipeline connection.

[0048] On the basis of the above-mentioned embodiments, according to the electric control box provided by the application, the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 can have different positional relationships with the first rotating part 15 and the second rotating part 16, for example, in a first example, as shown in Figure 14 and Figure 15 The first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are arranged in the same plane with the first rotating part 15 and the second rotating part 16, in this way, the central axis of the first rotating part 15 is coaxially arranged with the rotating shaft 12, and the central axis of the second rotating part 16 is coaxially arranged with the rotating shaft 12, which is beneficial to reduce the length of use of the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14, and make the overall structure layout more compact.

[0049] In a second example, as shown in Figures 4 to 13As shown, the plane where the first rotary member 15 and the second rotary member 16 are located is on the front side or the back side of the plane where the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are located, the front side refers to the side located on the front of the electric control box 10, and the back side refers to the side located on the back of the electric control box 10. In this way, the central axis of the first rotary member 15 is arranged in parallel with the rotating shaft 12, and the central axis of the second rotary member 16 is arranged in parallel with the rotating shaft 12, so that the arrangement of the rotary assembly is more flexible, and the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 also have multiple spatial arrangement modes.

[0050] Among them, the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 can adopt multiple shapes or spatial layouts, when the plane where the first rotary member 15 and the second rotary member 16 are located is on the front side or the back side of the plane where the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are located, as shown in Figure 4 and Figure 5 , the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are in continuous L shape, and the pipe is in smooth extension structure as a whole, which is convenient for processing. As shown in Figure 6 and Figure 7 , the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are in different shapes, as shown in Figure 8 and Figure 9 , the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are in continuous different shapes, and the pipe is in multi-segment bending connection structure, which increases the diversity of the shape of the pipe. As shown in Figure 10 and Figure 11 , the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are in L shape+different shape, as shown in Figure 12 and Figure 13 , the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are in continuous L shape+continuous different shape.

[0051] When the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are arranged on the same plane as the first rotary member 15 and the second rotary member 16, the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 can be in L shape, different shape, continuous different shape, L shape+different shape, continuous L shape+continuous different shape, etc., which can be arranged according to actual needs.

[0052] On the basis of the above-mentioned embodiments, in order to realize the relative rotation between the first rotary part 17 and the second rotary part 18, a sealing member and a bearing 24 are arranged between the first rotary part 17 and the second rotary part 18, as shown in Figure 2 In this embodiment, the first rotary part 17 is nested inside the second rotary part 18, the cooperation area of the first rotary part 17 and the second rotary part 18 is provided with multiple bearings 24 and multiple sealing rings 25, and the opening end of the second rotary part 18 is also provided with a bearing end cover 26. By arranging multiple sealing rings 25, liquid leakage can be prevented, and the sealing reliability can be ensured.

[0053] The third rotating part 19 and the fourth rotating part 20 are provided with a seal and a bearing, and the specific structure is referred to the matching structure between the first rotating part 17 and the second rotating part 18, which will not be described here.

[0054] The application also provides an air conditioner 11 comprising the electric control box of the above-mentioned embodiments and examples, which has all the structures and all the beneficial effects of the above-mentioned electric control box, which will not be described here.

[0055] The electric control box and the air conditioner 11 provided by the application can greatly reduce the operation difficulty and improve the efficiency, because when the structure on the back of the electric control box body 10 needs to be maintained or replaced, the electric control box body 10 only needs to be rotated to a convenient angle, without the need to completely disassemble the electric control box body 10, and without the need to disassemble the related wire harness and the refrigerant pipe, etc. Moreover, since the disassembly step in the early stage is omitted, after the maintenance is completed, there is no need to perform the reinstallation step, which can avoid the wire harness connection error and ensure the normal operation of the machine. It can be understood that for the structure of the air conditioner 11 arranged on the back side of the electric control box body 10, when the electric control box body 10 is rotated outward by a certain angle, it is also convenient for the staff to maintain the internal devices or structures, which provides operation convenience.

[0056] Further, the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 are connected with the refrigerant pipeline of the air conditioner 11 through the rotating assembly, so that the refrigerant system of the air conditioner 11 can be used to provide refrigerant for the heat dissipation of the electric control box body 10, thereby realizing the heat dissipation of the electric control box body 10 without the need of external refrigerant system, which is conducive to simplifying the structure configuration and reducing the cost. By arranging the rotating assembly, when the electric control box body 10 rotates relative to the air conditioner 11, the first rotating part 17 rotates relative to the second rotating part 18, and the third rotating part 19 rotates relative to the fourth rotating part 20, so that the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14 can rotate synchronously with the electric control box body 10 without bending or twisting deformation, which greatly reduces the influence of the rotation of the box body on the structure of the first refrigerant heat dissipation pipe 13 and the second refrigerant heat dissipation pipe 14, effectively prevents the pipe from cracking due to frequent deformation to cause leakage, prolongs the service life of the pipe, and ensures the safety and reliability of the refrigerant circulation.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the application, but not to limit them; although the application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the application.
