[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0042] Hard water can have various impacts on daily life and household appliances. For example, it can reduce washing effectiveness, accumulate in water pipes causing reduced water flow, impair the performance and lifespan of appliances, and even cause skin problems. Therefore, people use water softeners to treat tap water in their daily lives. Water softeners effectively remove minerals from hard water, improving water quality and enhancing the quality of life. Typically, water softeners work by using ion exchange to remove calcium and magnesium ions from the water, thus transforming hard water into soft water.

[0043] Typically, water softeners use resin exchange for water treatment. This resin is a polymer with a special structure and a positively charged surface. When hard water passes through the ion exchange resin column, the calcium and magnesium ions in the water are adsorbed onto the positively charged resin surface, replacing the original sodium ions. Water softening equipment requires multiple water channels for water softening and resin particle regeneration, and also needs to introduce brine and distribute water during regeneration.

[0044] In related technologies, to achieve the multiple water circuit functions of a water softener, it is usually achieved through the connection and mating of water circuit components with a resin tank. Specifically, the water circuit components are integrally molded, such as by injection molding, and multiple flow channels are constructed within the integrally molded water circuit components using a mold. This requires relatively complex mold design, which increases production costs and production time.

[0045] In related technologies, in order to achieve the switching of water flow direction in the resin tank of a water softener, that is, the forward and reverse circulation of water in the resin tank, the passage and some functional components are often integrated into the water circuit component. This further complicates the flow channels in the water circuit component, makes the mold extremely complex, increases the difficulty of preparation, and increases the manufacturing cost.

[0046] For issues related to the technology, see [link / reference]. Figures 1-3As shown, the present invention provides a flow channel assembly for use with a resin tank 600, including a first flow channel pipe 100, a first connecting pipe 300, a second flow channel pipe 200, and a second connecting pipe 400 to form a flow passage. The first flow channel pipe 100 has a first communication port 120 for communicating with the resin filling portion of the resin tank 600; the first connecting pipe 300 is fixedly connected to the first flow channel pipe 100 and the two are interconnected, wherein the first connecting pipe 300 is used for fluid input or fluid output; the second flow channel pipe 200 has a second communication port 220 for communicating with the central pipe 700 of the resin tank 600; the second connecting pipe 400 is fixedly connected to the second flow channel pipe 200 and the two are interconnected, wherein the second connecting pipe 400 is used for fluid input or fluid output. In the design of water circuit components, it is necessary to meet the switching of five functional channels in the water softener: water supply, backwashing, regeneration, water replenishment, and forward washing. Therefore, water circuit components usually integrate multiple flow channels into a single structure, which undoubtedly requires complex molding molds to construct multiple flow channels. In this embodiment, two flow channel pipes, namely the first flow channel pipe 100 and the second flow channel pipe 200, are used. The two flow channel pipes are respectively provided with connecting ports, namely the first connecting port 120 and the second connecting port 220. The two connecting ports can realize the connection between the two flow channel pipes and the resin tank 600, thereby realizing the switching of the flow direction within the resin tank 600.

[0047] It is understood that in this embodiment, the water path is guided by the first flow channel pipe 100 and the second flow channel pipe 200. A first connecting pipe 300 is connected to the first flow channel pipe 100, and a second flow channel pipe 200 is connected to the second flow channel pipe 200. When the fluid enters, the flow direction within the resin tank 600 is switched by selecting either the first connecting pipe 300 or the second connecting pipe 400, thus satisfying the switching of the five functional water paths in the water softener: water supply, backwashing, regeneration, water replenishment, and forward washing. It can be seen that this embodiment achieves the construction of multiple flow channels simply by connecting pipes to the resin tank 600, avoiding complex mold design. The entire circuit consists of a small number of pipes, simplifying the flow channel construction and reducing manufacturing difficulty and cost.

[0048] Understandably, the flow direction is generally defined as the water entering from the top of the resin filling section, flowing through the resin particles, and then exiting through the central pipe 700. The flow direction is defined as the water entering from the top of the central pipe 700, flowing through the central pipe 700 to the bottom, and then exiting through the bottom of the resin filling section after rising through the resin particles. In the five functions of the water softener, the water supply and replenishment are in the forward flow direction, while the remaining function channels are in the reverse flow direction.

[0049] In the specific setup, during water supply (forward flow), raw water enters the first flow channel pipe 100 through the first connecting pipe 300 and is softened by the resin particles in the resin tank 600. The treated water rises through the central pipe 700 and exits through the second flow channel pipe 200 and the second connecting pipe 400. At this time, the first connecting pipe 300 is used for fluid input, and the second connecting pipe 400 is used for fluid output. During regeneration (reverse flow), brine enters the second flow channel pipe 200 through the second connecting pipe 400 and enters the bottom of the resin tank 600 through the central pipe 700. The brine entering the bottom can rise along the outer part of the resin pipe to clean the resin particles, and then enters the first flow channel pipe 100 and exits through the first connecting pipe 300 in the first flow channel pipe 100. At this time, the first connecting pipe 300 is used for fluid output, and the second connecting pipe 400 is used for fluid input. Understandably, the flow direction within the resin tank 600 is switched by selecting the connection of two pipes, and the entire flow channel is constructed through two flow channel pipes, which simplifies the overall structure and reduces the difficulty of preparation and manufacturing cost.

[0050] In practical applications, the first flow channel pipe 100, the second flow channel pipe 200, the first connecting pipe 300, and the second connecting pipe 400 can be prepared separately. Connecting ports are respectively opened on the first flow channel pipe 100 and the second flow channel pipe 200 to achieve communication with the resin filling part of the resin tank 600 and the central pipe 700. Specifically, the first connecting pipe 300 can be connected to the first flow channel pipe 100 to form a first pipe group by welding or other methods, and the second connecting pipe 400 can be connected to the second flow channel pipe 200 to form a second pipe group. These two pipe groups are arranged to achieve separate communication with multiple bodies. It is understood that the solution of this embodiment, during production, can achieve product assembly through modular operations, enabling the simultaneous production and assembly of multiple modules, ultimately forming a complete product. This improves manufacturing and production efficiency, shortens the product design and development cycle, and facilitates resource utilization and recycling.

[0051] It is understood that the resin tank 600 in the various embodiments described in this application can adopt a conventional resin tank 600 structure, that is, a tank structure for filling resin particles, and an independent central tube 700 inside the tank. The resin filling part is located on the periphery of the central tube 700, and the water passage achieves functions such as softening by contacting the resin particles inside the resin tank 600.

[0052] In some specific applications, such as Figure 2As shown, at least one of the sections of the first flow channel 100 and the second flow channel 200 is located inside the resin tank 600. The outer portion of the resin tank 600 is filled with resin particles, and the center of the resin tank 600 has a central tube 700. The central tube 700 allows the fluid output from the central tube 700 to make uniform contact with the surrounding resin particles. The outer portion of the resin tank 600 needs to be connected to one of the flow channels, and the central portion of the resin tank 600, i.e., the central tube 700, also needs to be connected to a flow channel. In this embodiment, at least one section of the flow channel is located inside the resin tank 600, which allows the connection port to the outer portion to be directly opened on the tube body, reducing the difficulty of preparing the connection port.

[0053] When setting up the specific configuration, refer to... Figure 2 As shown, portions of the first flow channel pipe 100 and the second flow channel pipe 200 are both located within the resin tank 600. The first flow channel pipe 100 has a first connecting port 120 on its wall, which communicates with the outer periphery of the resin tank 600. It is understood that placing both flow channel pipes within the resin tank 600 further reduces the water flow path, thereby minimizing energy loss during water flow and improving water delivery performance.

[0054] In practical applications, continue to refer to Figure 2 As shown, the first connecting port 120 is opened along the extension direction of the first flow channel pipe 100, and the maximum dimension of the first connecting port 120 in the extension direction of the first flow channel pipe 100 is less than or equal to the dimension of the first flow channel pipe 100 located inside the resin tank 600 in the extension direction. The diameter of the first connecting port 120 affects the sufficiency and uniformity of contact with the resin. Because the first connecting port 120 is directly connected to the resin filling part, if the diameter of the first connecting port 120 is too small, it will affect the amount of water output. An excessively small outlet will result in limited water distribution, making it difficult to achieve uniform contact with the resin, thus causing insufficient contact. In this embodiment, the first connecting port 120 can be opened along the extension direction of the pipe body, and since part of the pipe body is located inside the resin tank 600, it can be flexibly opened as needed, enabling a larger diameter of the first connecting port 120 even if the pipe body diameter is small, thereby improving the water distribution effect.

[0055] In some specific examples, the cross-sectional area of ​​the first connecting port 120 is greater than or equal to the diameter area of ​​the longitudinal section of the first flow channel pipe 100. By limiting the size of the first connecting port 120, the sufficiency of water and resin particles can be improved, thereby enhancing the water delivery performance in the pipeline system. It is understood that a smaller diameter of the connecting port will have a certain impact on water delivery performance, including changes in flow velocity, increased pressure loss, diversion effects, and a possible increase in noise and vibration. In this embodiment, since the first connecting port 120 can be opened along the extension direction of the first flow channel pipe 100, and the diameter of the first connecting port 120 is larger than the inner diameter of the first flow channel pipe 100, the above-mentioned problems are avoided. Furthermore, opening it along the extension direction of the flow channel pipe can increase its distribution range on the periphery of the resin tank 600, thereby ensuring sufficient contact between the water and resin particles.

[0056] It is understood that, in this embodiment, since part of the pipe is located inside the resin tank 600, it can be opened along the extension direction of the flow channel pipe. This opening method will not affect the water delivery of the entire pipeline system. This opening method can achieve a larger outlet diameter and enable contact with a large area of ​​resin particles, thereby improving the uniformity and sufficiency of the contact between the water and the resin particles.

[0057] In practical applications, the aperture edges of the first connecting port 120 and / or the second connecting port 220 can be configured as an integral rounded corner structure. The rounded corner design can reduce pressure loss when fluid passes through the opening. Compared with sharp or right-angled edges, rounded corner edges can reduce the resistance and friction between the fluid and the edge, thereby reducing pressure loss; moreover, rounded corner edges can better guide the flow of fluid, reduce fluid separation and turbulence, improve fluid stability and transport efficiency, and avoid fluid separation or turbulence.

[0058] According to one embodiment of the present invention, the axis of the first connecting pipe 300 is perpendicular to the axis of the first flow channel pipe 100, and the axis of the second connecting pipe 400 is perpendicular to the axis of the second flow channel pipe 200. The first connecting pipe 300 and the second connecting pipe 400 are connected to the valve body, enabling water path switching and selective water input via the first connecting pipe 300 or the second connecting pipe 400. In this embodiment, the vertical arrangement of the first connecting pipe 300 and the first flow channel pipe 100 shortens the water path entering the first flow channel pipe 100, avoiding performance loss during water delivery. Furthermore, the vertical arrangement reduces manufacturing difficulty because, compared to an inclined arrangement, it is easier to position, allows for fluid introduction with less material, and facilitates better connection to the valve body. Similarly, the vertical arrangement of the second connecting pipe 400 and the second flow channel pipe 200 also reduces manufacturing difficulty.

[0059] For specific embodiments, see Figure 1 As shown, the first connecting pipe 300 and the second connecting pipe 400 protrude from the highest plane formed between the first flow channel pipe 100 and the second flow channel pipe 200, which facilitates the connection of the valve body. Furthermore, quick-connect holes are provided on the bodies of the first connecting pipe 300 and the second connecting pipe 400, allowing for quick-connection with the valve body and facilitating the connection of functional components such as the valve body. In a further example, the bodies of the first connecting pipe 300 and the second connecting pipe 400 also have protruding structures. These protruding structures are arranged along the extension direction of the pipe bodies, which on the one hand enhance the strength of the pipe bodies, and on the other hand guide the insertion of functional components such as the valve body.

[0060] According to one embodiment of the present invention, the flow channel assembly further includes an adapter 500 having at least one opening 530 for mating with a resin tank 600. Each opening 530 has a first communication port 120 and a second communication port 220, so that the first connecting pipe 300 is connected to the resin filling part through the first flow channel pipe 100, and the second connecting pipe 400 is connected to the central pipe 700 through the second flow channel pipe 200. It is understandable that the resin tank 600 is used for water treatment, and the resin tank 600 has a resin filling part filled with resin particles, which gives the resin tank 600 a certain mass. This requires the resin tank 600 to have a relatively stable connection structure. In this embodiment, an adapter 500 is provided on the lower end face of the channel, so that the adapter 500 is located at the lower end of the channel. An opening 530 is provided on the adapter 500, and the resin tank 600 is connected through the opening 530, which can improve the stability of the connection of the resin tank 600. The top of the resin tank 600 has a barrel opening, and the first connecting port 120 and the second connecting port 220 are both located inside the barrel opening. This allows the water entering the opening 530 to enter the resin tank 600 when the resin tank 600 is connected to the opening 530.

[0061] In a specific configuration, a portion of the first flow channel pipe 100 and a portion of the second flow channel pipe 200 are both located within the opening 530. The opening 530 is used to connect to the resin tank 600, specifically to the opening of the resin tank 600. In this embodiment, the pipe bodies of both flow channel pipes are located within the opening 530, and this portion of the pipe body is exposed to the resin tank 600 through the opening 530. This facilitates the configuration of the opening 530 and shortens the water path.

[0062] In a specific application, the adapter 500 includes a main body plate 510. One side of the main body plate 510 has a raised edge portion 520, which defines an opening 530. The other side of the main body plate 510 is connected to a first flow channel pipe 100 and a second flow channel pipe 200. The adapter 500 is used to connect to a resin tank 600 and can maintain the stability of the connection of the resin tank 600. In this embodiment, by having an edge portion 520 on one side of the main body plate 510, the edge portion 520 can form an opening 530 through which the resin tank 600 is connected, thereby improving the overall stability of the flow channel assembly structure.

[0063] In some specific embodiments, such as Figure 1 , Figure 3 As shown, the edge portion 520 forms a circular opening 530, and threads can be machined on the inner wall surface of the edge portion 520 to achieve the connection between the resin barrel 600 and the opening 530.

[0064] For specific examples, please refer to [link / reference]. Figure 1 , Figure 2 As shown, the adapter 500 has two openings 530 arranged side by side, each capable of connecting to a resin tank 600. Specifically, the first flow channel pipe 100 has two first connecting ports 120, each corresponding to a resin tank 600. The second flow channel pipe 200 has two second connecting ports 220, each corresponding to a resin tank 600. A first connecting pipe 300 is located between the two first connecting ports 120, and the second connecting ports 220 are also located between the two connecting ports. It can be understood that by placing the first connecting pipe 300 between two adjacent first connecting ports 120, the fluid entering the first flow channel pipe 100 through the first connecting pipe 300 can be diverted through the two first connecting ports 120, thus achieving a more uniform delivery of fluid to the two resin tanks 600. Similarly, the second connecting pipe 400 can also deliver the fluid more evenly to the central pipe 700 of the two resin tanks 600, which allows the input fluid, such as raw water, to fully contact the resin particles and improve the quality of water softening treatment.

[0065] According to one embodiment of the present invention, the tube body of the second flow channel 200 includes a main body and a protrusion 230. The sidewall of the main body extends parallel to the axis of the main body. The sidewall of the protrusion 230 protrudes from the main body and communicates with the main body, and the protrusion 230 communicates with the central tube 700. The central tube 700 is typically located at the center of the resin tank 600. In this embodiment, the protrusion 230 enables the fluid in the second flow channel 200 to be introduced into the central tube 700.

[0066] It is understandable that by having a protrusion 230 on the second flow channel tube 200, a certain distance is created between the first flow channel tube 100 and the second flow channel tube 200, and this distance forms an installation space for functional components such as valve bodies, thereby enabling a compact layout of the product.

[0067] In a specific configuration, the protrusion 230 is integrally formed with the second flow channel 200, thereby reducing the number of parts and improving the stability of the piping system. Furthermore, in application, the first flow channel 100 and the second flow channel 200 can be made of materials such as rigid plastic, or, in other specific applications, the first flow channel 100 and the second flow channel 200 can also be made of metal. In some examples, the first flow channel 100 and the second flow channel 200 can be made of the same material; of course, in other examples, the first flow channel 100 and the second flow channel 200 can also be made of different materials.

[0068] The protrusion 230 can be a tubular structure; however, it can also be a non-tubular structure, such as... Figure 2 , Figure 5 As shown, the protrusion 230 has an annular wall structure. When the protrusion 230 is a tubular structure, the second connecting port 220 is opened at the bottom of the protrusion 230, allowing the end of the central tube 700 to be inserted into the second connecting port 220 for communication. When the protrusion 230 has an annular wall structure, the annular sidewall structure forms the second connecting port 220. In this case, the second connecting port 220 is connected to the second flow tube, and the end of the central tube 700 is connected to the second connecting port 220 to form a circulating water channel.

[0069] In a specific configuration, the diameter of the second connecting port 220 is greater than or equal to the inner diameter of the central pipe 700. The upper end of the central pipe 700 is connected to the second connecting port 220, and the lower end of the central pipe 700 is connected to the body of the resin tank 600, so that fluid can be input from the central pipe 700 to the bottom of the resin tank 600, or fluid can rise from the bottom of the resin tank 600 along the central pipe 700. In other words, the second connecting port 220 serves as a connecting hole between the central pipe 700 and the second flow channel pipe 200. In this embodiment, limiting the diameter of the second connecting port 220 to be greater than or equal to the diameter of the central pipe 700 can improve the water conveyance performance of the pipeline system. Specifically, the principle is the same as that of the first connecting port 120; if the diameter of the first connecting port 120 is smaller than that of the central pipe 700, it will affect the water conveyance performance of the pipeline system.

[0070] According to one embodiment of the present invention, at least a portion of the first flow channel 100 and at least a portion of the second flow channel 200 are located within the adapter 500. During normal operation, the two flow channels need to carry a large amount of water, requiring them to have a stable structure. In this embodiment, when the flow channels are connected to the adapter 500, placing at least a portion of the pipe body within the adapter 500 increases the contact area between the adapter 500 and the two pipe bodies, thereby improving the stability of the connection.

[0071] Understandably, in practical applications, the entire bodies of the two flow channels can be submerged in the adapter 500 for connection. This connection method provides greater structural stability to the flow channels. However, this submersion method requires the adapter 500 to have sufficient thickness, which increases the material usage of the adapter 500, and the submersion method is inconvenient to operate during processing. See also Figure 1 , Figure 3 As shown, in this embodiment, a portion of the first flow channel tube 100 and the second flow channel tube 200 protrudes from the plane of the main body plate 510 of the adapter 500, while the remaining portion of the tube is located inside the adapter 500. This method can maintain the connection strength between the flow channel tube and the adapter 500, and also facilitates connection processing.

[0072] In a specific configuration, the upper surface of the first flow channel pipe 100 protruding from the adapter 500 includes a first plane 110, and the upper surface of the second flow channel pipe 200 protruding from the adapter 500 includes a second plane 210. The first plane 110 and the second plane 210 are coplanar. The flow channel assembly, as a component guiding the water flow, communicates with the resin tank 600. A valve body is often connected to the flow channel assembly. The valve body is used for actively controlling and switching the water flow. In this embodiment, the first plane 110 and the second plane 210 are provided on the first flow channel pipe 100 and the second flow channel pipe 200, which facilitates the assembly of the valve body through the two planes.

[0073] Understandably, the pipe wall is typically curved, with the curved surface higher than the plane of the main body plate 510, which is unfavorable for valve body assembly. Furthermore, the arrangement of two planes increases the contact area between the valve body and the planes after connection, improving the load-bearing capacity of the valve body and thus enhancing the stability of the overall connection structure. Moreover, the two planes facilitate direct connection of the valve body, resulting in a more compact overall structure and reduced product size.

[0074] In specific applications, the first plane 110 is located on the first flow channel pipes 100 on both sides of the first connecting pipe 300, and the second plane 210 is located on the second flow channel pipes 200 on both sides of the second connecting pipe 400. The planes reduce the wall thickness of the flow channel pipes. In this embodiment, the positions of the first connecting pipe 300 and the second connecting pipe 400 do not have planes, which makes the strength at the connecting pipe positions high and further improves the overall stability.

[0075] It is understandable that the first connecting pipe 300 and the second connecting pipe 400 are used to directly connect with the valve body. The water impact force at this location is relatively large. In this embodiment, the pipe body has a thickness at this location, which makes the overall structure strong and more stable.

[0076] According to one embodiment of the present invention, the first flow channel tube 100 and the second flow channel tube 200 are arranged in parallel. This parallel arrangement facilitates connection; during connection, one flow channel tube can be aligned with a reference point, and the remaining tube can be machined using the positioned flow channel tube as a reference, reducing manufacturing difficulty. Furthermore, it facilitates overall layout; the parallel arrangement provides better load-bearing capacity within the space between the two tubes. For example, in the above embodiment, by providing planes on the two tubes, the connection surfaces with the valve body are approximately equal, improving stability after installation.

[0077] In specific applications, the first connecting pipe 300 and the second connecting pipe 400 are offset on the same resin tank 600, and the two parallel flow channels are located on both sides of the resin tank 600. In this way, a clearance space is formed above the remaining resin tank 600, and the valve body can be installed in the clearance space, which further makes the overall structure compact.

[0078] In a specific configuration, the first flow channel 100 and the second flow channel 200 are symmetrically arranged with respect to the longitudinal section at the center of the opening 530. It can be understood that since a portion of the two flow channel tubes is located inside the resin tank 600, the first flow channel 100 and the second flow channel 200 will not exceed the outer diameter of the resin tank 600. That is, the entire first flow channel 100 and the entire second flow channel 200 are located inside the tank body, which further enhances the overall compactness of the structure.

[0079] The present invention also provides a water softener, including a resin tank 600 and a flow channel assembly as provided in any of the embodiments described above. The flow channel assembly is located on one side of the resin tank 600 in the axial direction and is fixedly connected to the resin tank 600.

[0080] Through the above description of the embodiments, those skilled in the art can clearly understand that each embodiment constructs the flow channel through two flow channel pipes, and forms a water path by setting connecting pipes on the respective flow channels. When softening is required, raw water is input through the first connecting pipe 300 and output through the second connecting pipe 400. When resin regeneration is required, brine is input through the second connecting pipe 400 and output through the first connecting pipe 300. Thus, the requirement for multiple water path circulation of the water softener is achieved through the connection of a small number of pipes, simplifying the overall structure, making it easy to manufacture, and reducing manufacturing costs.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
