Description

Technical Field

[0001] This utility model relates to the field of water softening equipment technology, and in particular to a water softener. Background Technology

[0002] A water softener is a water purification device that reduces the hardness of raw water, thus softening the water. The resin tank is the main structure of a water softener. Existing household water softeners use either fiberglass or a one-piece injection molding process for their resin tanks. Fiberglass tanks typically have a small opening at one end, which not only prevents the placement of larger water distributors, resulting in low resin utilization and poor resin regeneration efficiency, but also makes resin replacement more difficult. On the other hand, one-piece molded tanks generally use a disposable method for resin replacement, leading to higher replacement costs.

[0003] Therefore, how to develop a water softener that allows for convenient and low-cost resin replacement is a pressing technical problem that needs to be solved. Utility Model Content

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0041] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0043] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0044] This utility model provides a water softener, such as Figures 1 to 7 As shown, the water softener includes a resin tank 100, a water distributor assembly 200, an upper end cap 300, and a lower end cap 400. The resin tank 100 has a cylindrical structure. The top opening of the resin tank 100 forms a first opening 101, and the bottom opening of the resin tank 100 forms a second opening 102. An installation chamber is formed inside the resin tank 100. The water distributor assembly 200 can be placed inside the resin tank 100 through the first opening 101 or the second opening 102. A space for accommodating softened resin is formed between the water distributor assembly 200 and the resin tank 100. The upper end cap 300 is detachably sealed at the first opening 101, and the lower end cap 400 is detachably sealed at the second opening 102.

[0045] Compared to existing resin tank structures with only one mounting port, the resin tank 100 provided by this invention has two mounting ports: a first opening 101 and a second opening 102. Since an upper end cap 300 is detachably mounted at the first opening 101 and a lower end cap 400 is detachably mounted at the second opening 102, the water softener can either remove the upper end cap 300 to open the first opening 101 for resin replacement, or remove the lower end cap 400 to open the second opening 102 for resin replacement. It should be noted that after opening either the first opening 101 or the second opening 102, the entire water distributor assembly 200 can be poured out of the resin tank 100 for resin replacement; alternatively, the water distributor assembly 200 can be poured out through the gap between the water distributor assembly 200 and the resin tank 100, thereby replacing the resin. Users can flexibly choose the method of disassembling and replacing the resin according to their needs. The resin replacement method of the water softener is simple and convenient. Moreover, compared with the existing technology of replacing the entire resin tank structure in a disposable manner, the water softener of this utility model can replace only the softening resin without discarding the resin tank 100 and the water distributor assembly 200 inside the resin tank 100, thus making the resin replacement method more cost-effective.

[0046] Furthermore, the water distributor assembly 200 includes a detachably connected water distributor 210 and a central tube 220. This arrangement allows the water distributor assembly 200 to be disassembled and the softening resin replaced after opening the first opening 101 or the second opening 102.

[0047] Optionally, such as Figure 6 and Figure 7 As shown, the resin tank 100 has a cylindrical structure, which makes the opening size of both the first opening 101 and the second opening 102 larger, facilitating the replacement of the softening resin and making it easier to assemble and disassemble the water distributor assembly 200. Further optionally, the resin tank 100 has a cylindrical structure; or the resin tank 100 has a square cylindrical structure. In some embodiments, the resin tank 100 is a stainless steel cylinder.

[0048] To achieve a detachable connection between the upper end cap 300 and the resin tank 100, continue referring to section 4. Figure 6As shown, in some embodiments, the water softener also includes a locking plate 700, which is located above the upper end cap 300. A first slot 103 is formed on the top of the resin tank 100, and the edge of the locking plate 700 is inserted into the first slot 103. The locking plate 700 is detachably connected to the upper end cap 300. The water distributor assembly 200 is supported below the upper end cap 300 and adopts an assembly method in which the locking plate 700 is plugged into the resin tank 100 and detachably connected to the upper end cap 300. This method results in high assembly efficiency and good assembly stability.

[0049] Optionally, the locking plate 700 and the upper end cap 300 are detachably connected by screws. In one specific embodiment, the locking plate 700 has a first through hole, and the upper end cap 300 has a first threaded hole. A first screw passes through the first through hole and is threaded into the first threaded hole. Further, the locking plate 700 has multiple first through holes, and the upper end cap 300 has multiple first threaded holes, with each threaded hole corresponding to a first through hole. Each set of threaded holes and through holes contains a first screw. Of course, in other embodiments, the locking plate 700 and the upper end cap 300 can also be detachably connected using other methods, such as magnetic connection or snap-fit ​​connection.

[0050] To improve the assembly stability of the upper end cap 300 and the resin tank 100, the first slot 103 may optionally be a first annular slot, and the locking pieces 700 may be configured to be at least two, with the at least two locking pieces 700 spaced apart and both inserted into the first annular slot.

[0051] Optionally, the locking piece 700 is a fan-shaped locking piece. This design facilitates the insertion of the locking piece 700 into the first annular groove, and the arc-shaped edge of the locking piece 700 inserts into the first annular groove, resulting in a larger insertion area, which is beneficial to improving the stability after assembly. Of course, in other embodiments, the locking piece 700 can also be other shapes, such as fan-shaped, racetrack-shaped, etc.

[0052] To quickly position the resin tank 100 and the upper end cap 300, continue referring to... Figure 3 and Figure 5 As shown, the upper end cap 300 is snapped onto the top of the resin tank 100. Specifically, the top of the resin tank 100 is provided with a third slot 105, and the upper end cap 300 is provided with a first positioning claw 320, which snaps into the third slot 105. Optionally, the snapping positions of the resin tank 100 and the upper end cap 300 are offset from the locking plate 700 to facilitate installation. It should be noted that the number of third slots 105 can be set to one or more as needed, and correspondingly, the number of first positioning claws 320 can also be set to one or more as needed. Of course, the positions of the first positioning claws 320 and the third slots 105 can also be interchanged.

[0053] In one specific embodiment, the first positioning claw 320 has an L-shaped structure, and the third slot 105 has a U-shaped slot, with the horizontal portion of the first positioning claw 320 engaging within the U-shaped slot. Of course, in other embodiments, the first positioning claw 320 can also have an inverted U-shaped structure.

[0054] In some embodiments, the upper end cap 300 is provided with a first sealing ring groove in the circumferential direction, and the water softener also includes a first sealing ring, which is sleeved in the first sealing ring groove. After the upper end cap 300 is placed inside the top of the resin tank 100, the first sealing ring elastically abuts against the upper end cap 300 and the resin tank 100.

[0055] To achieve a detachable connection between the lower end cap 400 and the resin tank 100, continue referring to... Figure 2 and Figure 7 As shown, in some embodiments, the water softener further includes a lower locking plate 800, which is located below the lower end cap 400. A second slot 104 is formed at the bottom of the resin tank 100, and the edge of the lower locking plate 800 is inserted into the second slot 104. The lower locking plate 800 is detachably connected to the lower end cap 400. The lower end cap 400 is supported below the water distributor assembly 200. The assembly method, which involves the lower locking plate 800 being inserted into the resin tank 100 and detachably connected to the lower end cap 400, results in high assembly efficiency and good assembly stability.

[0056] Optionally, the lower locking plate 800 and the lower end cap 400 are detachably connected by screws. In one specific embodiment, the lower locking plate 800 has a second through hole, and the lower end cap 400 has a second threaded hole. A second screw passes through the second through hole and is threaded into the second threaded hole. Further, the lower locking plate 800 has multiple second through holes, and the lower end cap 400 has multiple second threaded holes, with each threaded hole corresponding to a second through hole. A second screw is installed in each set of threaded holes and through holes. Of course, in other embodiments, the lower locking plate 800 and the lower end cap 400 can also be detachably connected using other methods, such as magnetic connection or snap-fit ​​connection.

[0057] To improve the assembly stability of the lower end cap 400 and the resin tank 100, the second slot 104 may optionally be a second annular slot, and the lower locking piece 800 may be configured to be at least two, with the at least two lower locking pieces 800 spaced apart and both inserted into the second annular slot.

[0058] Optionally, the lower locking piece 800 is a fan-shaped locking piece. This design facilitates the insertion of the lower locking piece 800 into the second annular groove, and the arc-shaped edge of the lower locking piece 800 inserts into the second annular groove, resulting in a larger insertion area, which is beneficial to improving the stability after assembly. Of course, in other embodiments, the lower locking piece 800 can also be other shapes, such as fan-shaped, racetrack-shaped, etc.

[0059] To quickly position the resin tank 100 and the lower end cap 400, continue referring to... Figure 2 and Figure 6 As shown, the lower end cap 400 is snapped into the bottom of the resin tank 100. The bottom of the resin tank 100 has a fourth slot 106, and the lower end cap 400 has a second positioning claw 410, which snaps into the fourth slot 106. Optionally, the snapping positions of the resin tank 100 and the lower end cap 400 are offset from the lower locking plate 800 to facilitate installation. It should be noted that the number of fourth slots 106 can be one or more, depending on the requirements. Correspondingly, the number of second positioning claws 410 can also be one or more, depending on the requirements. Of course, the positions of the second positioning claws 410 and the fourth slot 106 can also be interchanged.

[0060] In one specific embodiment, the second positioning claw 410 has an L-shaped structure, and the fourth slot 106 has a U-shaped slot, with the horizontal portion of the second positioning claw 410 engaging within the U-shaped slot. Of course, in other embodiments, the second positioning claw 410 can also have an inverted U-shaped structure.

[0061] In some embodiments, the lower end cap 400 is provided with a second sealing ring groove in the circumferential direction, and the water softener also includes a second sealing ring, which is sleeved in the second sealing ring groove. After the lower end cap 400 is placed in the bottom of the resin tank 100, the second sealing ring elastically abuts against the lower end cap 400 and the resin tank 100.

[0062] Continue to refer to Figure 1 and Figure 2 As shown, the water softener also includes a control valve 500, which is used to control and switch the water channels within the water softener. In some embodiments, the control valve 500 is detachably connected to the upper end cap 300. Optionally, as... Figure 8As shown, the water softener also includes a connector 600. The upper end cap 300 includes a tubular first water hole portion 310, and the control valve 500 includes a tubular second water hole portion 510. The first water hole portion 310 and the second water hole portion 510 are plugged into each other. One of the first water hole portions 310 and the second water hole portion 510 is provided with a socket 311 on the outer side, and the other is provided with a slot 511 on the inner side. The plug-in portion of the connector 600 passes through the socket 311 and is plugged into the slot 511. The detachable connection method of using the connector 600 and the pipe plug-in engagement provides high assembly stability and high disassembly efficiency.

[0063] In one specific embodiment, the connector 600 has a U-shaped structure with two sockets 311 and an annular groove 511. The U-shaped connector 600 has two insertion parts, each of which is inserted into a socket 311 and confined within the slot 511. Of course, in other embodiments, the connector 600 may also be a rod-shaped structure.

[0064] Furthermore, the upper end cap 300 is provided with two tubular first water holes 310, and correspondingly, the control valve 500 is provided with two tubular second water holes 510. The two tubular first water holes 310 and the two tubular second water holes 510 are inserted into each other in a one-to-one manner. When the water softener softens water, one set of the inserted first water holes 310 and second water holes 510 is positioned opposite the water distributor 210 and is used to supply raw water. The other set of inserted first water holes 310 and second water holes 510 is connected to the central pipe 220 and is used to supply softened water. Inside the water softener, brine can be introduced in the reverse direction of the raw water flow to regenerate the softening resin.

[0065] The water distributor assembly 200 is positioned between the upper end cap 300 and the lower end cap 400 to isolate the softening resin and prevent its leakage. For example... Figure 9 As shown, in some embodiments, the water distributor 210 includes a plate-shaped upper water distributor 211 and a lower water distributor 212. The upper water distributor 211 is detachably connected to the top of the central pipe 220, and the lower water distributor 212 is detachably connected to the bottom of the central pipe 220. Exemplarily, raw water entering the resin tank 100 from the upper end cap 300 is dispersed by the plate-shaped upper water distributor 211 and uniformly enters the softening resin from the top, where water softening is performed; while brine entering from the central pipe 220 is dispersed by the plate-shaped lower water distributor 212 and uniformly enters the softening resin from the bottom, where softening resin is regenerated.

[0066] It should be noted that when replacing the softening resin by disassembling the upper end cap 300, simply remove the upper water distributor 211 after disassembling the upper end cap 300; similarly, when replacing the softening resin by disassembling the lower end cap 400, simply remove the lower water distributor 212 after disassembling the lower end cap 400. Furthermore, the upper water distributor 211 and lower water distributor 212 are detachably connected to the central tube 220, facilitating repair of both. If either the upper water distributor 211 or lower water distributor 212 is damaged, only the upper end cap 300 needs to be removed for replacement, or only the lower end cap 400 needs to be removed for replacement, making the process convenient and quick.

[0067] In some embodiments, such as Figure 10 and Figure 11 As shown, the lower water distributor 212 includes a softening water distributor 2121 and a regeneration water distributor 2122. The softening water distributor 2121 is located above the regeneration water distributor 2122. The central pipe 220 includes a first central pipe 221 and a second central pipe 222. The first central pipe 221 is sleeved outside the second central pipe 222 and is connected to the softening water distributor 2121. The regeneration water distributor 2122 is connected to the second central pipe 222. A first soft water channel is formed between the softening water distributor 2121 and the regeneration water distributor 2122, and a second soft water channel is formed between the first central pipe 221 and the second central pipe 222. The second soft water channel communicates with the first soft water channel and forms part of the softening channel. A first brine channel is formed between the regeneration water distributor 2122 and the lower end cap 400. A second brine channel is formed inside the second central pipe 222. The first brine channel communicates with the second brine channel and forms part of the regeneration channel. This configuration separates the softening channel and the regeneration channel, forming a dual water replenishment scheme for softening and regeneration. During the resin regeneration process, the brine can be evenly distributed throughout the entire 100 cross-sectional layer of the resin tank, allowing the softening resin to be fully regenerated and improving the utilization rate of the brine.

[0068] In some embodiments, a first positioning ring is provided circumferentially at the top of the first central tube 221, and the upper water distributor 211 is sleeved on the top of the first central tube 221 and limited and supported on the first positioning ring; a second positioning ring is provided circumferentially at the bottom of the first central tube 221, and the softening water distributor 2121 is sleeved on the top of the first central tube 221 and limited below the second positioning ring. It should be noted that, as... Figure 4 As shown, the number of central tubes 220 can also be only one.

[0069] Continue to refer to Figure 9As shown, in some embodiments, the upper water distributor 211 is provided with multiple elongated flow gaps 2111. The width of the flow gaps 2111 is small, and the multiple flow gaps 2111 are arranged in a ring around the circumference of the upper water distributor 211, with multiple rings. This arrangement can ensure that the softened water quality is not exposed and can also ensure the softening flow rate. In one embodiment, the plate-shaped upper water distributor 211 is approximately equal in size to the cross-sectional size of the resin tank 100.

[0070] In some embodiments, the regeneration distributor 2122 is provided with a plurality of regeneration holes for supplying brine, and the regeneration holes are evenly distributed on the regeneration distributor 2122. This arrangement ensures that during the regeneration of the softening resin, the resin regenerant (e.g., brine) can flow out evenly from the regeneration holes, so that the softening resin laid on the entire interface layer of the resin tank 100 can be fully regenerated, without creating dead zones where the resin cannot be fully regenerated. Optionally, the regeneration holes are conical holes, and designing the regeneration holes as conical holes facilitates the cleaning of the regenerated resin.

[0071] In some embodiments, the upper end cap 300 has a first water hole 330 and a plurality of second water holes 340 arranged circumferentially around the first water hole 330. The first water hole 330 is for brine to enter and the second water holes 340 are for soft water to flow out. The central tube 220 includes a first central tube 221 and a second central tube 222. The first central tube 221 is sleeved outside the second central tube 222. The top end of the second central tube 222 communicates with the first water hole 330. The annular opening formed between the first central tube 221 and the second central tube 222 communicates with the plurality of second water holes 340.

[0072] In some embodiments, the first water hole 330 forms an inlet port and an outlet port on both sides of the upper end cap 300, respectively, and the inlet port and outlet port are offset in the thickness direction of the upper end cap 300. This arrangement facilitates assembly.

[0073] Continue to refer to Figure 12 As shown, when the water softener is configured to have a first central pipe 221 and a second central pipe 222, the flow direction of the water in the resin softening water path of the water softener is as follows: the raw water enters the resin tank 100 through the first water hole 310, which is directly opposite the flow gap 2111 of the upper water distributor 211. Then the raw water is dispersed by the upper water distributor 211 and flows into the softening resin layer for softening. After softening, the soft water forms and flows through the softening water distributor 2121, through the first soft water channel, the second soft water channel and the second water hole 340 connected to the first central pipe 221, and finally flows out through another first water hole 310.

[0074] Continue to refer to Figure 13As shown, when the water softener is configured to have a first central pipe 221 and a second central pipe 222, the flow direction of the water in the resin regeneration water path of the water softener is as follows: the brine enters through the first water hole 310 connected to the second central pipe 222, and reaches the first brine flow channel through the second central pipe 222 to form a second brine flow channel. Then, it flows to the softening resin layer through the regeneration small holes evenly distributed on the regeneration water distributor 2122. The wastewater generated after resin regeneration passes through the upper water distributor 211 and finally flows out from the first water hole 310 directly opposite the flow gap 2111 of the upper water distributor 211.

[0075] The water softener also includes a control mechanism. In this embodiment, the control mechanism can be a centralized or distributed controller. For example, the controller can be a single microcontroller or a combination of multiple distributed microcontrollers. The microcontroller can run a control program to control the control valve 500 to achieve its function.
