Description

Technical Field

[0001] This application relates to, but is not limited to, the field of household appliance technology, specifically to a water collector, an indoor air conditioning unit, and an air conditioning device. Background Technology

[0002] In related technologies, the indoor unit of an air conditioner includes an indoor heat exchanger, in which water flows as the refrigerant. It needs to be connected to the refrigerant inlet pipe and the refrigerant outlet pipe through two water collectors, respectively. The overall structure is complex and the cost is high. Utility Model Content

[0003] The technical problem to be solved by this application is to provide a water collector, an indoor air conditioning unit, and an air conditioning device, which helps to simplify the structure of the indoor air conditioning unit and reduce costs.

[0004] This application provides a water collector, which includes a pipe connector, a cover plate, and multiple water distribution pipes. The pipe connector, the cover plate, and the multiple water distribution pipes are a separate assembly structure. The pipe connector includes a connector portion and an expansion portion. The connector portion is provided with a connecting portion for connecting to an external pipeline. One end of the expansion portion is connected to one end of the connector portion, and the flow cross-sectional area of ​​the other end of the expansion portion is larger than the flow cross-sectional area of ​​the end of the expansion portion connected to the connector portion. The cover plate covers the end of the expansion portion away from the connector portion and is connected to the expansion portion. The cover plate is provided with multiple piping holes that communicate with the internal space of the pipe connector. The multiple water distribution pipes are inserted one by one into the corresponding piping holes and fixedly connected to the cover plate.

[0005] This application improves the structure of the water collector by splitting the original complex connector into a pipe connector and a cover plate. The pipe connector connects to external pipelines, and the cover plate connects to multiple branch pipes. This eliminates the assembly process and machining work required for the connectors, as well as the need for complex and extensive machining of the outer wall of the pipe connector and the absence of an intermediate transition section. This simplifies the structure of both the pipe connector and the cover plate compared to the original connector, facilitating separate fabrication and assembly. This simplifies the structure of the water collector, effectively reduces machining work, and helps lower the cost of the air conditioning indoor unit. Furthermore, the expansion section increases the flow cross-sectional area of ​​the pipe connector facing the cover plate, correspondingly increasing the area of ​​the cover plate without requiring the original curved structure to increase the area, thus meeting the requirements for the number of branch pipes.

[0006] Based on the above technical solution, the following improvements can be made to this application.

[0007] In an exemplary embodiment, the water collector further includes: a limiting plate, which is stacked on the surface of the cover plate near the expansion portion and connected to the cover plate and / or the expansion portion. The limiting plate is provided with positioning holes that correspond one-to-one with the plurality of pipe holes. 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 expansion portion facing the cover plate is provided with a first recessed platform, and the limiting plate is located within the first recessed platform and flush with the end face of the expansion portion facing the cover plate; or, the limiting plate is located outside the expansion portion and abuts against the end face of the expansion portion facing the cover plate, and the limiting plate is flush with the outer wall of the expansion portion; or, the end of the expansion portion facing the cover plate is provided with a first recessed platform, and the limiting plate and the cover plate are located within the first recessed platform.

[0011] In one exemplary embodiment, the pipe fitting is a one-piece structure; and / or, the water distribution pipe is a stainless steel pipe.

[0012] In one exemplary embodiment, the water collector further includes a mounting plate with assembly holes, the mounting plate protruding radially outward from the pipe joint; wherein the mounting plate is integrally formed with the cover plate; or, the mounting plate is integrally formed with the expansion portion.

[0013] In one exemplary embodiment, the cover plate is a flat plate structure, and the central axis of the pipe hole is aligned with the thickness direction of the cover plate; the water distribution pipe includes a plug section and an extension section, the plug section is inserted and fixed into the corresponding pipe hole, and the extension section is connected to the plug section and bent relative to the plug section.

[0038] 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.

[0039] 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 10 to 12As 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' increase 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 to the connector 2'. The connector 2' is used to connect to 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' is provided with multiple piping holes for installing the distribution pipes 3'. The sidewalls of the cap bottom 13' are designed with a petal-shaped outline, requiring extensive machining. The bottom wall is designed as a curved surface protruding away from the connector 11' to maximize surface area for mounting more water distribution pipes 3'. Multiple piping holes are spaced circumferentially along the cap bottom 13', with one piping hole per petal. The transition section 12' serves as the transition between the connector 11' and the cap bottom 13'. In this design, the water collector has a very complex structure, requiring extensive machining to form, resulting in high machining volume and cost.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] like Figures 1 to 4 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.

[0044] 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.

[0045] like Figure 5 and Figure 6 As shown, the pipe fitting 1 includes a fitting portion 13 and an expansion portion 122. The fitting portion 13 is provided with a connecting portion 111 for connecting to external pipelines (such as a refrigerant inlet pipe or a refrigerant outlet pipe). The connecting portion 111 can be, but is not limited to, a threaded connection portion, as shown in the figure. Figure 7 , Figure 8 As shown in Figures 1 and 2, the threaded connection can be either internal or external thread. This eliminates the need for additional connectors in the water collector, saving the assembly process between the joint and the connecting parts.

[0046] like Figure 5 and Figure 6 As shown, one end of the expansion section 122 is connected to one end of the connector section 13, and the flow cross-sectional area of ​​the other end of the expansion section 122 is larger than the flow cross-sectional area of ​​the end of the expansion section 122 connected to the connector section 13. The cover plate 2 covers the end of the expansion section 122 away from the connector section 13 and is connected to the expansion section 122. The cover plate 2 has multiple piping holes that communicate with the internal space of the pipe connector 1. Multiple water distribution pipes 3 are inserted into their corresponding piping holes and fixedly connected to the cover plate 2. These multiple water distribution pipes 3 are connected to multiple inlet pipes or multiple outlet pipes. The expansion section 122 increases the flow cross-sectional area of ​​the pipe connector 1 facing the cover plate 2, which helps to increase the number of water distribution pipes 3 that can be connected.

[0047] The cover plate 2 and the pipe joint 1 can be fixedly connected by welding, but not limited to welding, ensuring a 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, ensuring a reliable connection and good sealing.

[0048] 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 connects to external pipelines, and the cover plate 2 connects to multiple branch pipes 3. This eliminates the assembly process and machining work required for the connecting parts, and also eliminates the need for complex and extensive machining of the outer wall of the pipe joint 1, as well as the need for an intermediate transition section. This effectively simplifies the structure of both the pipe joint 1 and the cover plate 2 compared to the original joint, making them easier to process and assemble separately. This simplifies the structure of the water collector, effectively reduces machining work, and helps lower the cost of the air conditioner indoor unit. Furthermore, the expansion section 122 increases the flow cross-sectional area of ​​the pipe joint 1 facing the cover plate 2, thus increasing the area of ​​the cover plate 2 accordingly. This eliminates the need for the original curved structure to increase the area, allowing the cover plate 2 to meet the required number of branch pipes 3.

[0049] In some exemplary embodiments, the flow cross-sectional area of ​​the expansion portion 122 tends to increase along the direction away from the connector portion 13, so that the structure of the expansion portion 122 is more regular, which is convenient for processing and forming, and also helps to reduce flow resistance.

[0050] In some exemplary embodiments, such as Figures 5 to 8 As shown, the water collector also includes a limiting plate 4, which is stacked on the surface of the cover plate 2 near the expansion portion 122 and connected to the cover plate 2 and / or the expansion portion 122. The limiting plate 4 is provided with positioning holes 41 that correspond one-to-one with multiple pipe holes. The diameter of the positioning holes 41 is smaller than the outer diameter of the water distribution pipes 3, so that the multiple water distribution pipes 3 abut against the limiting plate 4 and are connected to the corresponding positioning holes 41.

[0051] 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.

[0052] Furthermore, the multiple piping holes 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.

[0053] 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.

[0054] In some embodiments, such as Figure 5 As shown, the end of the expansion portion 122 facing the cover plate 2 is provided with a first recessed platform 1221, and the limiting plate 4 is limited within the first recessed platform 1221 and is flush with the end face of the expansion portion 122 facing the cover plate 2.

[0055] In other embodiments, such as Figure 7 As shown, the limiting plate 4 is located outside the expansion portion 122 and abuts against the end face of the expansion portion 122 facing the cover plate 2, and the limiting plate 4 is flush with the outer side wall of the expansion portion 122.

[0056] In some other embodiments, such as Figure 6 and Figure 8 As shown, the end of the expansion portion 122 facing the cover plate 2 is provided with a first recessed platform 1221, and the limiting plate 4 and the cover plate 2 are limited within the first recessed platform 1221.

[0057] By placing the limiting plate 4 within the first recess 1221 of the pipe joint 1, the limiting plate 4 can be effectively positioned during assembly, facilitating its rapid assembly and fixation. Furthermore, this allows the limiting plate 4 to be concealed within the pipe joint 1, reducing the volume of the water collector and minimizing its assembly space requirements.

[0058] Alternatively, the limiting plate 4 and the cover plate 2 can be together positioned within the first recess 1221 of the pipe joint 1, which provides good positioning for the assembly of the limiting plate 4 and the cover plate 2, facilitating their quick assembly and fixation. Furthermore, this allows the limiting plate 4 and the cover plate 2 to be concealed inside the pipe joint 1, reducing the joint's volume and minimizing its assembly space requirements.

[0059] Alternatively, the limiting plate 4 can be located outside the pipe joint 1, sandwiched between the pipe joint 1 and the cover plate 2, which can also limit the insertion depth of the water distribution pipe 3 and improve the concentricity of the assembly of the cover plate 2 and the pipe joint 1. Furthermore, this solution can eliminate the first countersunk platform 1221 inside the pipe joint 1, which helps to simplify the structure of the pipe joint 1 and thus reduces the amount of machining required for the pipe joint 1.

[0060] In other embodiments, such as Figure 9As shown, the cover plate 2 abuts against the end face of the expansion portion 122 facing the cover plate 2, and the thickness of the cover plate 2 can be appropriately increased. In other words, the connector of the water collector may not include the limiting plate 4, and the cover plate 2 directly contacts and connects with the pipe connector 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.

[0061] In some exemplary embodiments, such as Figure 5 , Figure 7 , Figure 8 and Figure 9 As shown, pipe connector 1 includes connector component 11 and adapter 2. Adapter 2 includes a contraction section 121 and an expansion section 122. A second recessed platform 112 is provided at one end of the connector component near the cover plate 2. The contraction section 121 is confined within the second recessed platform 112 and connected to the connector component 11. Connector 13 includes connector component 11 and contraction section 121. The contraction section 121 may be cylindrical.

[0062] In this way, the connector component 11 can be a tubular structure with uniform thickness, which is simple in structure and easy to process and form. Alternatively, the connector assembly can also be a standard part that can be purchased directly, which can save the processing steps of the connector component 11.

[0063] In other embodiments, such as Figure 6 As shown, the pipe connector 1 is a one-piece molded structure, which can eliminate the connection process between the connector component 11 and the adapter 2.

[0064] In some exemplary embodiments, such as Figure 2 and Figure 3 As shown, the water collector also includes a mounting orifice plate 7, which has an assembly hole 71 and protrudes outward from the pipe joint 1 along the radial direction of the pipe joint 1.

[0065] Among them, the mounting plate 7 and the cover plate 2 are integrally formed, such as Figure 3 As shown. Alternatively, the mounting plate 7 and the expansion section 122 are integrally formed.

[0066] This eliminates the need for processing and assembly steps for installing the orifice plate 7, which helps improve the production efficiency of the water collector.

[0067] When the mounting plate 7 and the cover plate 2 are integrally formed, the cover plate 2 is located outside the expansion portion 122. When the mounting plate 7 and the expansion portion 122 are integrally formed, the cover plate 2 can be located inside the expansion portion 122 and cover the port of the expansion portion 122.

[0068] In some exemplary embodiments, such as Figures 5 to 9As shown, the cover plate 2 has a flat plate structure, and the central axis of the pipe hole is aligned with the thickness direction of the cover plate 2. Correspondingly, the water distribution pipe 3 includes a plug section and an extension section. The plug section is inserted and fixed into the corresponding pipe hole, and the extension section is connected to the plug section and bent relative to the plug section.

[0069] 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 inclined pipe holes, nor petal-shaped outer walls, nor curved end walls. Therefore, the structure is more regular, easier to process and form, and helps to reduce machining and reduce costs.

[0070] 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.

[0071] In some exemplary embodiments, such as Figures 5 to 9 As shown, the outer wall of the connector 13 is cylindrical. Compared with the three-section stepped shape of the original connector, the structure of the connector 13 in this solution is simpler and more regular, which helps to reduce the amount of machining and facilitates processing and forming.

[0072] In some exemplary embodiments, the outer wall of the expansion portion 122 includes a frustum surface, such as... Figure 5 As shown, it may also include a cylindrical surface, which may be located on the side of the frustum away from the joint portion 13.

[0073] In some exemplary embodiments, the side wall of the pipe connector 1 of the water collector is provided with an air vent. The air vent may be offset from the connection portion 111. The water collector also includes an air vent valve connector 5, such as... Figure 2 As shown, the vent valve connector 5 is connected to the vent port. The vent valve connector 5 and the pipe connector 1 can be fixedly connected by welding, but are 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 10 Understanding the vent valve 5' in the middle.

[0074] In other embodiments, the side wall of the pipe connector 1 may not have a vent, and the water collector may not include the vent valve connector 5, such as... Figures 8 to 5 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.
