This eliminates the assembly process and machining amount of the connecting parts, as well as the machining and welding process of the installation orifice plates. It also eliminates the need for complex and extensive machining of the outer wall of the pipe joint and the need to set up intermediate transition parts. As a result, the structures of the pipe joint and the cover plate are effectively simplified compared to the original joint, making it easier to process and shape them separately and then assemble them.

The diameter of the positioning hole is smaller than the outer diameter of the water distribution pipe, so that the plurality of water distribution pipes abut against the limiting plate and are connected to the corresponding positioning holes.

[0008] In one exemplary embodiment, the end of the pipe joint facing the cover plate is provided with a recessed platform, and the limiting plate is located within the recessed platform and flush with the end face of the pipe joint facing the cover plate; or, the limiting plate is located outside the pipe joint and abuts against the end face of the pipe joint facing the cover plate, and the limiting plate is flush with the outer wall of the pipe joint.

[0009] In one exemplary embodiment, the cover plate abuts against the end face of the pipe fitting.

[0042] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0043] Research has found that one reason for the complex structure and high cost of air conditioning indoor units in related technologies is the complex structure of the water collector, which requires significant machining and thus increases costs. The structure of the water collector is as follows: Figures 16 to 18 As shown. The water collector includes a connector 1', a connector 2' installed on the connector 1', and multiple distribution pipes 3'. The connector 1' is an integral structure, including a connector portion 11', a transition portion 12', and a cover bottom 13' arranged sequentially along the axial direction. The outer diameters of the connector portion 11', transition portion 12', and cover bottom 13' decrease sequentially, forming a three-section structure, which requires extensive machining of the outer wall of the connector 1'. The interior of the connector portion 11' needs to be machined with steps for subsequent fixation with the connector 2'. The connector 2' is used to connect with an external mounting carrier to fix the water collector. The outer wall of the connector portion 11' is provided with a mounting plate 4', which is fixed to the connector portion 11' by welding. The cover bottom 13' has multiple piping holes for installing the distribution pipes 3'. The side walls of the cover bottom 13' are designed with a petal-shaped outline, and the bottom wall is designed as a curved surface protruding away from the connector portion 11', which also requires extensive machining. Multiple piping holes are spaced circumferentially along the bottom of the cover 13', with one piping hole per petal. The transition section 12' serves as the transition between the connector section 11' and the bottom of the cover 13'. In this design, the water collector has a very complex structure, requiring extensive machining to form, resulting in high machining volume and cost.

[0044] This application provides a water collector, an indoor air conditioning unit including the water collector, and an air conditioning system including the indoor air conditioning unit. The air conditioning system can be a central air conditioning system.

[0045] The indoor unit of an air conditioner includes a casing, a fan, and a heat exchanger assembly. A partition is provided inside the casing, dividing the internal space into a fan chamber and a heat exchange chamber. The fan chamber has an air inlet on its wall, and the heat exchange chamber has an air outlet on its wall. The partition has a vent connecting the fan chamber and the heat exchange chamber. The fan is located inside the fan chamber, with its inlet corresponding to the air inlet and its outlet corresponding to the vent. The heat exchanger assembly is located inside the heat exchange chamber, between the vent and the air outlet. After the fan starts, airflow enters the casing through the air inlet, passes through the fan into the heat exchange chamber, exchanges heat with the heat exchanger assembly, and then flows out through the air outlet.

[0046] The heat exchanger assembly includes an indoor heat exchanger (with water flowing inside) that is connected to the refrigerant inlet and outlet pipes of an air conditioning unit, and two water collectors connected to the indoor heat exchanger. The indoor heat exchanger is a multi-loop indoor heat exchanger, having multiple inlet pipes and multiple outlet pipes. One of the water collectors is configured to connect between the multiple inlet pipes and the refrigerant inlet pipe, and can be referred to as the inlet-end water collector. The other water collector is configured to connect between the multiple outlet pipes and the refrigerant outlet pipe, and can be referred to as the outlet-end water collector.

[0047] like Figure 1 , Figure 2 and Figure 8 As shown, the water manifold includes: a pipe connector 1, a cover plate 2, and multiple branch pipes 3. The pipe connector 1, cover plate 2, and branch pipes 3 are a separate assembly structure. The water manifold includes this connector and multiple branch pipes 3. The pipe connector 1 is used to connect to external piping (such as a refrigerant inlet or outlet pipe), and the multiple branch pipes 3 are used to connect to an indoor heat exchanger with multiple loops. The branch pipes 3 can be, but are not limited to, stainless steel pipes, which are less expensive than copper pipes. Of course, the branch pipes 3 can also be copper pipes or pipes of other materials.

[0048] When pipe connector 1 is connected to the refrigerant inlet pipe and multiple branch pipes 3 are connected to the inlet pipe of the indoor heat exchanger, the water collector is an inlet-end water collector, used to transport the refrigerant from the refrigerant inlet pipe to the indoor heat exchanger through the multiple branch pipes 3. When pipe connector 1 is connected to the refrigerant outlet pipe and multiple branch pipes 3 are connected to the outlet pipe of the indoor heat exchanger, the water collector is an outlet-end water collector, used to collect and output the refrigerant output from the indoor heat exchanger. The inlet-end and outlet-end water collectors are used together to realize the refrigerant input and output of the indoor heat exchanger, thereby realizing the refrigerant circulation of the entire unit.

[0049] The pipe fitting 1 is provided with a connecting part 12 for connecting to an external pipe. The connecting part 12 can be, but is not limited to, a threaded connecting part 12, such as... Figure 1 , Figure 7 , Figure 8 , Figure 13 and Figure 14 As shown. The threaded connection 12 can be either internal or external thread. In this way, the water collector does not require additional connecting parts, eliminating the assembly process between the connector and the connecting parts.

[0050] like Figure 1 , Figure 3 , Figure 5 , Figure 8 , Figure 9 ,and Figure 11 As shown, the cover plate 2 includes a main body 21 and a mounting plate 22 connected to the main body 21 and having mounting holes 221. The mounting plate 22 is integrally formed with the main body 21, as shown in the figure. Figure 1 and Figure 8 As shown, this eliminates the need for the machining and welding processes of the mounting plate 22. The plate body 21 covers one end of the pipe connector 1 and is connected to the pipe connector 1. The plate body 21 also has multiple piping holes 211 that communicate with the internal space of the pipe connector 1, such as... Figure 1 and Figure 8 As shown.

[0051] Multiple water distribution pipes 3 are inserted into corresponding pipe holes 211 and fixedly connected to the cover plate 2. The multiple water distribution pipes 3 are configured to connect with multiple inlet pipes or multiple outlet pipes of the indoor heat exchanger.

[0052] The plate body 21 and the pipe joint 1 can be fixedly connected by welding, but not limited to welding, with reliable connection and good sealing. Similarly, each water distribution pipe 3 and the cover plate 2 can be fixedly connected by welding, but not limited to welding, with reliable connection and good sealing.

[0053] This application embodiment improves the structure of the water collector by splitting the original complex joint into a pipe joint 1 and a cover plate 2. The pipe joint 1 has the function of connecting to external pipelines, and the cover plate 2 has the function of installing a perforated plate 22 and connecting multiple branch pipes 3. This eliminates the assembly process and machining of the connecting parts, as well as the machining and welding process of the perforated plate. It also eliminates the need for complex and extensive machining of the outer wall of the pipe joint 1 and the need for an intermediate transition part. As a result, the structures of the pipe joint 1 and the cover plate 2 are effectively simplified compared to the original joint, making it easier to process and assemble them separately. This simplifies the structure of the water collector, effectively reduces the amount of machining, and helps to reduce the cost of the air conditioning indoor unit.

[0054] In some exemplary embodiments, such as Figure 1 , Figure 4 , Figure 7 , Figure 8 , Figure 10 , Figure 13 and Figure 15 As shown, the water collector also includes: a limiting plate 4, which is stacked on the plate surface of the plate body 21 near the pipe joint 1 and connected to the cover plate 2 and / or the pipe joint 1. The limiting plate 4 is provided with positioning holes 41 that correspond one-to-one with multiple pipe holes 211. The diameter of the positioning hole 41 is smaller than the outer diameter of the water distribution pipe 3, so that the multiple water distribution pipes 3 of the water collector can abut against the limiting plate 4 and connect with the corresponding positioning holes 41, such as... Figure 7 and Figure 13 As shown.

[0055] In this way, each water distribution pipe 3 can only be inserted to the position that abuts against the limiting plate 4, thus limiting the insertion depth of each water distribution pipe 3, preventing the water distribution pipe 3 from being inserted too deeply or too shallowly, and making it less likely to sway or shake during assembly, which helps to improve the assembly consistency of the water collector.

[0056] Furthermore, the multiple pipe holes 211 of the cover plate 2 need to be connected one-to-one with the multiple positioning holes 41 of the limiting plate 4, which is equivalent to adding multiple positioning structures to the cover plate 2. This helps to avoid the cover plate 2 being placed eccentrically relative to the pipe joint 1, thereby improving the concentricity of the assembly of the cover plate 2 and the pipe joint 1.

[0057] The limiting plate 4 and the pipe joint 1 can be fixedly connected by welding, but not limited to welding, ensuring a reliable connection and good sealing. Similarly, the limiting plate 4 and the cover plate 2 can be fixedly connected by welding, but not limited to welding, ensuring a reliable connection and good sealing.

[0058] In some embodiments, the end of the pipe fitting 1 facing the cover plate 2 is provided with a countersunk platform 11, such as... Figure 7 and Figure 13 As shown, the limiting plate 4 is located within the recessed platform 11 and is flush with the end face of the pipe joint 1 facing the cover plate 2.

[0059] In other embodiments, the limiting plate 4 is located outside the pipe joint 1 and abuts against the end face of the pipe joint 1 facing the cover plate 2, and the limiting plate 4 is flush with the outer side wall of the pipe joint 1, such as... Figure 14 As shown.

[0060] By placing the limiting plate 4 inside the recessed platform 11 of the pipe joint 1, the limiting plate 4 can be effectively positioned during assembly, facilitating its quick assembly and fixation. Furthermore, this allows the limiting plate 4 to be concealed inside the pipe joint 1, reducing the volume of the water collector and minimizing its assembly space requirements.

[0061] Alternatively, the limiting plate 4 can be located outside the pipe joint 1, sandwiched between the pipe joint 1 and the cover plate 2. This also serves to limit the insertion depth of the water distribution pipe 3 and improve the concentricity of the assembly between the cover plate 2 and the pipe joint 1. Furthermore, this solution eliminates the need for the countersunk platform 11 inside the pipe joint 1, which simplifies the structure of the pipe joint 1 and reduces the amount of machining required.

[0062] In other embodiments, such as Figure 15 As shown, the cover plate 2 abuts against the end face of the pipe joint 1, and the thickness of the cover plate 2 can be appropriately increased. In other words, the joint of the water collector may not include the limiting plate 4, and the cover plate 2 directly contacts and connects with the pipe joint 1. By appropriately increasing the thickness of the cover plate 2, the assembly reliability of the water distribution pipe 3 and the cover plate 2 can also be improved.

[0063] In some exemplary embodiments, the mounting plate 22 is configured to protrude radially outward from the plate body 21 along the pipe joint 1. The cover plate 2 has a flat plate structure, and the central axis of the pipe hole 211 is aligned with the thickness direction of the cover plate 2. Correspondingly, the water distribution pipe 3 includes a plug section 31 and an extension section 32. The plug section 31 is inserted and fixed into the corresponding pipe hole 211, and the extension section 32 is connected to the plug section 31 and bent relative to the plug section 31.

[0064] Therefore, compared with the bottom of the original connector, the structure of the cover plate 2 in this embodiment is also greatly simplified. It has neither an inclined pipe hole 211, nor a petal-shaped outer wall, nor a curved end wall. Therefore, the structure is more regular, easier to process and form, and helps to reduce machining and reduce costs.

[0065] In some exemplary embodiments, the cover plate 2 can be integrally formed by casting, punching, or other methods, and then punched. Alternatively, the cover plate 2 can be obtained by directly punching holes after purchasing standard parts.

[0066] In some exemplary embodiments, the pipe fitting 1 is a one-piece structure, for example, it is integrally formed by casting, stretching, stamping, etc., and then the connecting part 12 is machined. Alternatively, the pipe fitting 1 can also be a standard part, which can be obtained directly by purchase, thus eliminating the need for machining the pipe fitting 1.

[0067] In some exemplary embodiments, such as Figure 1 As shown, the outer wall of the pipe joint 1 is cylindrical. Compared with the original three-section stepped joint, the structure of the pipe joint 1 in this solution is simpler and more regular, which helps to reduce the amount of machining and facilitates processing and forming.

[0068] In some exemplary embodiments, such as Figure 1 As shown, the side wall of the pipe joint 1 of the water collector is provided with an air vent 13. The air vent 13 can be offset from the connection part 12. The water collector also includes an air vent valve joint 5, such as... Figures 1 to 7 As shown, the vent valve connector 5 is connected to the vent port 13. The vent valve connector 5 and the pipe connector 1 can be fixedly connected by welding, but not limited to welding, ensuring a reliable connection and good sealing. The water collector may also include a vent valve connected to the vent valve connector 5. The structure of the vent valve can be found in [reference needed]. Figure 16 Understanding the vent valve 5' in the middle.

[0069] In other embodiments, the side wall of the pipe connector 1 may not have a vent 13, and the water collector may not include the vent valve connector 5, such as... Figures 8 to 15 As shown. For example: the inlet water collector and the outlet water collector used together can have an air release valve connector 5 and an air release valve on the outlet water collector, while the inlet water collector may not have an air release valve connector 5 and an air release valve.
