[0040] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0041] The following is for reference. Figures 1-6 Describes a branch box according to an embodiment of the present utility model.

[0042] Reference Figure 1 and Figure 2 The branch box 100 according to an embodiment of the present utility model includes: a mounting box body 30 and a functional component 20.

[0043] Functional component 20 is housed within mounting enclosure 30 and includes at least one of a current distribution component and a junction box assembly 27. For example, functional component 20 may include only a current distribution component, or it may include only a junction box assembly 27, or it may include both a current distribution component and a junction box assembly 27. The current distribution component is used to connect the refrigerant flow path of outdoor unit 10 to the refrigerant flow path of indoor unit 11, and the junction box assembly 27 is used to connect the outdoor unit 10 electrical control box of outdoor unit 10 to the indoor unit 11 electrical control box of indoor unit 11. The current distribution component and the junction box assembly 27 are each independently installed within the mounting enclosure and are both detachable.

[0044] The distributor assembly is used to connect the refrigerant flow path of the indoor unit 11 to the refrigerant flow path of the outdoor unit 10. It can concentrate the pipe connection points between the indoor unit 11 and the outdoor unit 10 in the branch box 100, so that the maintenance or installation of the pipe connection points can be carried out in the branch box 100, thereby improving the efficiency of pipe installation and maintenance.

[0045] The junction box assembly 27 is used to connect the outdoor unit 10's electrical control box and the indoor unit 11's electrical control box, thereby enabling electrical connection between the indoor unit 11 and the outdoor unit 10. For example, the junction box assembly 27 can be used to connect the communication lines of the outdoor unit 10 and the indoor unit 11, thus concentrating the communication line connection points of the indoor unit 11 and the outdoor unit 10 within the junction box assembly 27. As another example, the junction box assembly 27 can be used to connect the power cord of the outdoor unit 10 and the power cord of the indoor unit 11, thereby concentrating the power cord connection points of the indoor unit 11 and the outdoor unit 10 within the junction box assembly 27, achieving integrated connection and on / off control of the power cords. When the functional component 20 includes the junction box assembly 27, the wiring connection points between the indoor unit 11 and the outdoor unit 10 can be concentrated within this branch box 100, allowing maintenance or installation of the wiring connection points to be carried out within the branch box 100, improving the efficiency of wiring installation and maintenance.

[0046] For example, the hub assembly 27 can be removed from the mounting box 30 so that only the splitter assembly is installed in the mounting box 30; or the splitter assembly can be removed from the mounting box 30 so that only the hub assembly 27 is installed in the mounting box 30.

[0047] For example, the mounting box 30 can simultaneously house a splitter assembly and a hub assembly 27.

[0048] By independently installing and removing both the branching component and the hub assembly 27 within the mounting box 30, the different functions of the branch box 100 can be modularized. Different modules can be added for different application scenarios, meeting user needs while reducing resource consumption. For example, when multiple functions are required, multiple components can be installed within the mounting box 30 to fully meet user needs; when a single function is required, a single component can be installed within the mounting box 30, avoiding the waste of unnecessary component functions due to installing multiple components and saving resources.

[0049] By including at least one of a splitter component and a hub assembly 27 as the functional components, and by independently installing both the splitter component and the hub assembly 27 within the mounting box 30 and making them both removable, when a single functional module is required, only one of the splitter component and the hub assembly 27 is installed within the mounting box 30, avoiding unnecessary functional waste caused by installing multiple functional modules and saving resources. When multiple functional modules are required, both the splitter component and the hub assembly 27 can be installed within the mounting box 30, giving the branch box 100 multiple functional modules. Whether one or two functional modules are needed, these modules can be installed in or removed from the mounting box 30. This modularizes the different functions of the branch box 100, allowing for modular design of the branch box 100 according to functional requirements for different application scenarios. For example, different functional modules can be placed according to different needs to meet user requirements, making the branch box 100 suitable for various scenarios.

[0050] According to the branch box 100 of this utility model embodiment, by including functional components, and the functional components including at least one of a shunt component and a hub component, the line connection points and / or pipe connection points between the indoor unit and the outdoor unit can be concentrated in the branch box. This allows the maintenance or installation of the line connection points and / or pipe connection points to be carried out in the branch box, improving the efficiency of line and / or pipe installation and maintenance. By making the shunt component and the hub component independently installed in the mounting box and both detachable, the different functions of the branch box can be modularized. The branch box can be modularly designed according to functional needs for different application scenarios. For example, different functional modules can be placed according to different needs, which can meet different needs while reducing resource consumption and lowering costs.

[0051] According to some embodiments of this utility model, refer to Figures 2-5The mounting box 30 is provided with a cable outlet hole 40 and a conduit outlet hole 50. The cable outlet hole 40 is used for cable exit from the junction box assembly 27. The cable harness exiting from the cable outlet hole 40 can be connected to the control box of the indoor unit 11 or the control box of the outdoor unit 10. The conduit outlet hole 50 is used for the conduit outlet of the splitter assembly. The conduit outlet hole 50 can be connected to the conduit of the outdoor unit 10 or the conduit of the indoor unit 11. By providing the cable outlet hole 40 on the mounting box 30 for cable exit from the junction box assembly 27, the cable outlet hole 40 can limit and facilitate the exit of the cable harness, preventing the cable harness from getting tangled or interfering with other components inside the mounting box 30, and also facilitating the routing of the cable harness. By providing the conduit outlet hole 50 on the mounting box 30 for the conduit outlet of the splitter assembly, the arrangement of conduits can be facilitated.

[0052] According to some embodiments of the present invention, refer to 2 and Figure 6 The junction box assembly 27 includes an electrical control assembly 28, which includes a power cord assembly 281 for connecting the power cord of the indoor unit 11 to the power cord of the outdoor unit 10. By including the power cord assembly 281 in the electrical control assembly 28 and connecting the power cord assembly 281 to the power cord of the indoor unit 11 and the outdoor unit 10, the power cords of the indoor unit 11 and the outdoor unit 10 can be integrated into the junction box assembly 27. This allows relevant personnel to perform construction, inspection, and maintenance centrally within the junction box assembly 27, improving the efficiency of installation and repair.

[0053] According to some embodiments of this utility model, refer to Figure 2 and Figure 6 The junction box assembly 27 includes an electrical control assembly 28, which in turn includes a communication assembly 29. The communication assembly 29 is used to connect the communication lines of the indoor unit 11 and the outdoor unit 10. By including the communication assembly 29 in the electrical control assembly 28 and connecting the communication lines of the indoor unit 11 and the outdoor unit 10, multiple connection points of the communication lines of the indoor unit 11 and the outdoor unit 10 can be integrated within the junction box assembly 27. This allows relevant personnel to perform construction, inspection, and maintenance centrally within the junction box assembly 27, improving the efficiency of installation and repair.

[0054] According to some embodiments of this utility model, refer to Figures 2-5The mounting box 30 is provided with an indoor communication outlet hole 42 and an outdoor communication outlet hole 41. The indoor communication outlet hole 42 is used for the communication line of the indoor unit 11 to go out to the outside of the mounting box 30, and the outdoor communication outlet hole 41 is used for the communication line of the outdoor unit 10 to go out to the outside of the mounting box 30. By providing an indoor communication cable outlet 42 and an outdoor communication cable outlet 41 to the mounting box 30, and by having the indoor communication cable outlet 42 for the communication cable of the indoor unit 11 and the outdoor communication cable outlet 41 for the communication cable of the outdoor unit 10, the indoor communication cable outlet 42 can act as a cable outlet and limiter for the communication cable of the indoor unit 11, and the outdoor communication cable outlet 41 can act as a cable outlet and limiter for the communication cable of the outdoor unit 10. This prevents the communication cables of the indoor unit 11 or the outdoor unit 10 from getting tangled or moving around in the junction box assembly 27, which could interfere with other components. Furthermore, the communication cables of the indoor unit 11 and the outdoor unit 10 can be routed separately to distinguish communication cables from different devices, reducing the impact between the communication cables of the indoor unit 11 and the outdoor unit 10.

[0055] According to some embodiments of the present invention, the diversion assembly includes at least one of a first diversion component 21 and a second diversion component 24. For example, the diversion assembly may include only the first diversion component 21, or only the second diversion component 24, or a diversion assembly may include both the first diversion component 21 and the second diversion component 24. The first diversion component 21 is used to connect the liquid refrigerant pipeline of the outdoor unit 10 to the liquid refrigerant pipeline of the indoor unit 11, and the second diversion component 24 is used to connect the gaseous refrigerant pipeline of the outdoor unit 10 to the gaseous refrigerant pipeline of the indoor unit 11. The first diversion component 21 and the second diversion component 24 are each independently installed within the mounting housing 30 and are both detachable.

[0056] By having the first shunt component 21 and the second shunt component 24 independently installed within the mounting housing 30 and both removable, different modules can be disassembled or installed for different application scenarios, meeting user needs while reducing resource consumption. For example, only the first shunt component 21 can be installed within the mounting housing 30; or only the second shunt component 24 can be installed within the mounting housing 30; or both the first shunt component 21 and the second shunt component 24 can be installed within the mounting housing 30.

[0057] For example, the flow distribution assembly includes the first flow distribution component 21 and the second flow distribution component 24 mentioned above. When the air conditioning system 101 is cooling, the compressor discharges the compressed refrigerant through the compressor's exhaust port and flows into the outdoor heat exchanger of the outdoor unit 10. The refrigerant flowing through the outdoor heat exchanger flows into the first flow distribution component 21. The refrigerant flowing into the first flow distribution component 21 flows into the indoor heat exchangers of multiple indoor units 11 respectively. The refrigerant flowing through the multiple indoor heat exchangers flows into the second flow distribution component 24 for collection. The refrigerant flowing through the second flow distribution component 24 flows into the compressor through the compressor's return port and is compressed again.

[0058] For example, the flow distribution assembly includes the first flow distribution component 21 and the second flow distribution component 24 mentioned above. When the air conditioning system 101 is heating, the compressor discharges the compressed refrigerant through the compressor's exhaust port and flows into the second flow distribution component 24. The refrigerant flowing into the second flow distribution component 24 flows into the indoor heat exchangers of multiple indoor units 11 respectively. The refrigerant flowing through the multiple indoor heat exchangers flows into the first flow distribution component 21 for collection. The refrigerant flowing through the first flow distribution component 21 flows into the outdoor heat exchanger of the outdoor unit 10. The refrigerant flowing through the outdoor heat exchanger flows into the compressor through the compressor's return port and is compressed again.

[0059] According to some embodiments of this utility model, refer to Figures 2-5 The first diversion component 21 includes a first main pipe 22 and multiple first branch pipes 23. All first branch pipes 23 are connected to and communicate with the first main pipe 22. The first main pipe 22 is used to connect to the liquid refrigerant pipeline of the outdoor unit 10, and the multiple first branch pipes 23 are respectively used to connect to the liquid refrigerant pipelines of multiple indoor units 11. By including the first main pipe 22 and multiple first branch pipes 23 in the first diversion component 21, and by using the first main pipe 22 to connect to the liquid refrigerant pipeline of the outdoor unit 10, and the multiple first branch pipes 23 to connect to the liquid refrigerant pipelines of multiple indoor units 11, the first diversion component 21 can conveniently combine or divert the flowing refrigerant. For example, when the air conditioning system 100 is cooling, the refrigerant flowing through the outdoor unit 10 flows into the first main pipe 22 of the first diversion component 21, and the refrigerant flowing into the first main pipe 22 is diverted to the multiple first branch pipes 23, which then flow into the multiple indoor units 11. For example, when the air conditioning system 100 is heating, the refrigerant flowing through multiple indoor units 11 flows into the first branch pipe 23 of the first branch component 21, and the refrigerant flowing through multiple first branch pipes 23 flows into the first main pipe 22 for convergence before flowing into the outdoor unit 10.

[0060] According to some embodiments of this utility model, refer to Figures 2-5The second diversion component 24 includes a second main pipe 25 and a plurality of second branch pipes 26. The plurality of second branch pipes 26 are all connected to and communicate with the second main pipe 25. The second main pipe 25 is used to connect to the gaseous refrigerant pipeline of the outdoor unit 10, and the plurality of second branch pipes 26 are respectively used to connect to the gaseous refrigerant pipelines of the plurality of indoor units 11. By including a second main pipe 25 and multiple second branch pipes 26 in the second diversion component 24, and by connecting the second main pipe 25 to the gaseous refrigerant pipeline of the outdoor unit 10, and connecting the multiple second branch pipes 26 to the gaseous refrigerant pipelines of the multiple indoor units 11, the second diversion component 24 facilitates the convergence or diversion of the incoming refrigerant. For example, when the air conditioning system 100 is cooling, the refrigerant flowing out of the multiple indoor units 11 flows into the second branch pipes 26 of the second diversion component 24, and the refrigerant flowing through the multiple second branch pipes 26 flows into the second main pipe 25 for convergence before flowing into the outdoor unit 10. When the air conditioning system 100 is heating, the refrigerant discharged from the outdoor unit 10 flows into the second main pipe 25 of the second diversion component 24, and the refrigerant flowing through the second main pipe 25 is diverted to the multiple second branch pipes 26, and flows into the multiple indoor units 11 through the multiple second branch pipes 26 respectively.

[0061] According to some embodiments of this utility model, refer to Figures 2-5 Both the first main pipe 22 and the second main pipe 25 are straight pipes. By making both the first main pipe 22 and the second main pipe 25 straight pipes, the structure of the first main pipe 22 and the second main pipe 25 can be simplified and made easier to manufacture. It also makes it easier to arrange the first main pipe 22 and the second main pipe 25 and make their installation more convenient.

[0062] According to some embodiments of this utility model, refer to Figures 2-5 The extension directions of the first main pipe 22 and the second main pipe 25 are consistent. By making the extension directions of the first main pipe 22 and the second main pipe 25 consistent, it is easier to arrange the first main pipe 22 and the second main pipe 25, which is conducive to achieving a compact arrangement of the first main pipe 22 and the second main pipe 25, and makes the installation of the first main pipe 22 and the second main pipe 25 more convenient.

[0063] According to some embodiments of this utility model, refer to Figures 2-5The mounting box 30 has multiple outlet holes 50, including a first main outlet hole 51, multiple first branch outlet holes 52, a second main outlet hole 53, and multiple second branch outlet holes 54.

By forming multiple outlet holes 50 on the mounting box 30, and by using the first main outlet hole 51 for the first main pipe 22, the first branch outlet hole 52 for the first branch pipe 23, the second main outlet hole 53 for the second main pipe 25, and the second branch outlet hole 54 for the second branch pipe 26, the first main pipe 22, the first branch pipe 23, the second main pipe 25, and the second branch pipe 26 can exit through different outlet holes 50 respectively; and the outlet holes 50 play a limiting and supporting role for the pipeline, which can reduce the deformation of the pipeline under its own weight.

[0064] According to some embodiments of this utility model, refer to Figures 2-5 The first main outlet hole 51 and the second main outlet hole 53 are located on the same side of the mounting box 30. Since both the first main pipe 22 and the second main pipe 25 need to be connected to the outdoor unit 10, by making the direction and arrangement of the first main pipe 22 and the second main pipe 25 closer together, and by making the first main outlet hole 51 and the second main outlet hole 53 on the same side of the mounting box 30, it is easier to connect the first main pipe 22 and the second main pipe 25 to the outdoor unit 10.

[0065] According to some embodiments of this utility model, refer to Figures 2-5 Multiple first branch pipe holes 52 and multiple second branch pipe holes 54 are located on the same side of the mounting box 30. Since both the first branch pipe 23 and the second branch pipe 26 need to be connected to the indoor unit 11, by making the directions and arrangements of the multiple first branch pipes 23 and the multiple second branch pipes 26 closer together, and by making the multiple first branch pipe holes 52 and the multiple second branch pipe holes 54 located on the same side of the mounting box 30, it is easier to connect the first branch pipes 23 and the second branch pipes 26 to the indoor unit 11.

[0066] According to some embodiments of this utility model, refer to Figures 2-5 The first main outlet 51 and the first branch outlet 52 are located on different sides of the mounting box 30. Since the first main pipe 22 is connected to the outdoor unit 10 and the first branch pipe 23 is connected to the indoor unit 11, and the outdoor unit 10 and the indoor unit 11 are usually located in different positions, the outlet positions and / or directions of the first main pipe 22 and the first branch pipe 23 are different. By making the first main outlet 51 and the first branch outlet 52 located on different sides of the mounting box 30, it is convenient for the first main pipe 22 to exit and connect to the outdoor unit 10, and it is also convenient for the first branch pipe 23 to exit and connect to the indoor unit 11.

[0068] According to some embodiments of this utility model, refer to Figures 2-5 The first main outlet hole 51 and the first branch outlet hole 52 are located on adjacent sides of the mounting housing 30. By placing the first main outlet hole 51 and the first branch outlet hole 52 on adjacent sides of the mounting housing 30, it is easier to connect the first main pipe 22 to multiple first branch pipes 23, making the connection arrangement between the first main pipe 22 and the first branch pipes 23 more compact. For example, the first main pipe 22 can extend in the left-right direction, the first branch pipes 23 can extend in the front-back direction, and multiple first branch pipes 23 can be arranged in the left-right direction, with each first branch pipe 23 connected to the first main pipe 22.

[0069] According to some embodiments of this utility model, refer to Figures 2-5 The junction box assembly 27 includes a communication component 29, which connects the communication lines of the indoor unit 11 and the outdoor unit 10. The mounting box 30 is provided with an indoor communication outlet hole 42 for the communication line of the indoor unit 11 and an outdoor communication outlet hole 41 for the communication line of the outdoor unit 10. By providing indoor and outdoor communication outlet holes in the electrical control box, and by using the indoor communication outlet hole for the communication line of the indoor unit 11 and the outdoor communication outlet hole for the communication line of the outdoor unit 10, the indoor communication outlet hole and the outdoor communication outlet hole can limit the communication line of the indoor unit 11 and the outdoor communication outlet hole, respectively, thus preventing the communication lines of the indoor unit 11 and the outdoor unit 10 from getting tangled or moving around in the junction box assembly 27 and interfering with other components.

[0074] By having the first side plate 34 and the first side portion 331 of the base box 33 jointly define the first main outlet hole 51 and the second main outlet hole 53, it is easier to install the first main pipe 22 into the first main outlet hole 51 and the second main pipe 25 into the second main outlet hole 53. For example, the first main pipe 22 can be accommodated in a portion of the first main outlet hole 51 of the first side portion 331, and the second main pipe 25 can be accommodated in a portion of the second main outlet hole 53 of the first side portion 331. Then, the first side plate 34 is installed on the base box 33, so that the first main pipe 22 is installed in the first main outlet hole 51 and the second main pipe 25 is installed in the second main outlet hole 53.

[0075] By including a detachably connected cover plate 351 and an intermediate support plate in the second side plate 35, and by having the intermediate support plate and the second side portion 332 of the base box 33 jointly define one of the first outlet hole 52 and the second outlet hole 54, and the intermediate support plate and the cover plate 351 jointly define the other of the first outlet hole 52 and the second outlet hole 54, it is easier to install the first branch pipe 23 into the first outlet hole 52 and easier to install the second branch pipe 26 into the second outlet hole 54.

[0076] For example, the intermediate support plate and the second side 332 of the base box 33 together define the first outlet hole 52, and the intermediate support plate and the cover plate 351 together define the second outlet hole 54. When installing the first branch pipe 23 and the second branch pipe 26, the first branch pipe 23 is installed into the branch box 100, so that the first branch pipe 23 is accommodated in part of the first outlet hole 52 of the second side 332. The intermediate support plate is connected to the second side 332. Then the second branch pipe 26 is installed into the branch box 100, so that the second branch pipe 26 is accommodated in part of the second outlet hole 54 of the intermediate support plate. Finally, the cover plate 351 is connected and installed to the intermediate support 352.
