Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment technology, and in particular to a water distribution device and a water softener. Background Technology
[0002] A water softener is a device used to remove hardness ions from water, commonly used in homes and industrial settings. Hardness ions mainly include calcium and magnesium ions, which combine with other substances in the water to form limescale, damaging pipes, equipment, and appliances. Water softeners use ion exchange technology to exchange hardness ions with sodium ions, thus softening the water.
[0003] A water softener typically includes a water circuit valve, a resin tank, and a water distributor. The water distributor is located inside the resin tank, with resin filling the space between the tank and the distributor. Water entering through the water circuit valve flows into the resin tank via the water distributor. The water distributor usually includes a central pipe and an upper distribution valve connected to the central pipe, which guides the water flow outwards. However, the inlet of the water circuit valve is often eccentric, meaning the inlet is off-center relative to the water distributor. This causes the water flowing into the resin tank to be unevenly distributed, resulting in low utilization of the resin layer. Utility Model Content
[0004] The purpose of this invention is to provide a water distribution device and a water softener to solve the technical problem of uneven water distribution in the prior art.
[0005] Based on the above concept, the technical solution adopted by this utility model is as follows:
[0006] A water distribution device includes a water circuit valve and a first water distribution assembly disposed below the water circuit valve. The water circuit valve has an inlet and an outlet. The first water distribution assembly includes: a first manifold having a manifold cavity connected to the inlet, the cross-sectional area of the manifold cavity gradually decreasing from top to bottom; and a first collector disposed below the first manifold, the first collector having a first water collection cavity and a plurality of first water passage holes connected to the first water collection cavity, water flowing out of the manifold cavity entering the first water collection cavity, and the plurality of first water passage holes guiding the water in the first water collection cavity to disperse outward.
[0007] Preferably, the first distribution unit is snapped into the first busbar; or, the first distribution unit can be detached from the first busbar by rotating relative to the first busbar.
[0008] Preferably, the upper end of the first collector is inserted into the mounting cavity on the outer periphery of the first manifold. The inner wall of the mounting cavity is provided with a plurality of second locking protrusions, and the outer wall of the first collector is provided with a plurality of second locking slots. By rotating the first collector, the second locking protrusions can be inserted into the second locking slots.
[0009] Preferably, the first collection and distribution includes a first inner wall panel and a first outer wall panel, the first inner wall panel and the first outer wall panel forming the first water collection cavity, and the first outer wall panel having the first water passage hole.
[0010] Preferably, the first outer wall panel is in the shape of an inverted cone, and the first inner wall panel is in the shape of a cylinder.
[0011] Preferably, the first water passage extends in an elongated shape along the axial direction of the first outer wall plate, and a plurality of the first water passages are arranged at circumferential intervals around the first outer wall plate.
[0012] Preferably, the first manifold includes a water-guiding edge located below the water inlet and disposed at the top of the manifold cavity to guide water flow into the manifold cavity.
[0013] Preferably, the first water distribution assembly further includes a first base, the first base having a lifting cavity, the lower end of the first distribution assembly being inserted into the lifting cavity, the lifting cavity being arranged in a ring around the circumference of the first distribution assembly, the first water passage being connected to the lifting cavity, and water flowing out of the first water passage overflowing from the upper end of the lifting cavity.
[0014] Preferably, the water distribution device further includes a central pipe, the water valve is disposed at the top of the central pipe, the first water distribution component is sleeved on the upper part of the central pipe, the first manifold is arranged in a ring around the central pipe, and the first collector and distributor are arranged in a ring around the central pipe.
[0015] A water softener includes a resin tank and a water distribution device as described above, wherein the water valve is disposed at the opening of the resin tank.
[0016] The beneficial effects of this utility model are as follows: The water distribution device proposed in this utility model has a water valve with an inlet and an outlet. The first water distribution component is located on the lower side of the water valve. The water entering through the inlet flows into the confluence chamber. Since the cross-sectional area of the confluence chamber gradually decreases from top to bottom, the inlet is larger and the outlet is smaller during the flow of water through the confluence chamber, which buffers the water flow and makes the water flow converge, thus playing a role in uniform water flow to a certain extent. The water flowing out of the confluence chamber enters the first water collection chamber and is guided to flow outward through the first water passage hole, so as to evenly distribute the water. Therefore, by combining the first confluence component and the first distribution component, uniform water flow distribution can be achieved. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0045] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0046] See Figures 1 to 21 This embodiment provides a water distribution device, including a water valve 10 and a first water distribution assembly 20. The water valve 10 has an inlet 11 and an outlet 12, and the first water distribution assembly 20 is disposed on the lower side of the water valve 10. The first water distribution assembly 20 includes a first manifold 22 and a first distributor 23. The first manifold 22 has a manifold cavity 221, which is connected to the inlet 11. The cross-sectional area of the manifold cavity 221 gradually decreases from top to bottom. The first distributor 23 is disposed on the lower side of the first manifold 22. The first distributor 23 has a first water collection cavity 231 and a plurality of first water passage holes 232 connected to the first water collection cavity 231. The first water collection cavity 231 is connected to the manifold cavity 221, and the plurality of first water passage holes 232 guide the water in the first water collection cavity 231 to disperse and flow outward.
[0047] Water entering through inlet 11 flows into confluence chamber 221. As the cross-sectional area of confluence chamber 221 gradually decreases from top to bottom, the inlet is larger and the outlet is smaller as the water flows through confluence chamber 221, thus buffering the water flow and causing it to converge, which to a certain extent plays a role in uniform water flow. Water flowing out of confluence chamber 221 enters first collection chamber 231 and is guided to disperse outward through first water passage 232, thus distributing the water evenly. Therefore, by cooperating with first confluence component 22 and first distribution chamber 23, uniform water flow distribution can be achieved.
[0048] The first concentrator 23 is located below the first collector 22. The lower opening of the first collector 22 is smaller than the top opening of the first water collection cavity 231, facilitating the entry of water flowing out of the first collector 22 into the first water collection cavity 231. Alternatively, the lower edge of the first collector 22 may be lower than the upper edge of the first concentrator 23, meaning the lower end of the first collector 22 is inserted into the first water collection cavity 231, allowing water flowing out of the concentrator cavity 221 to enter the first water collection cavity 231. Alternatively, the lower edge of the first collector 22 may not be lower than the upper edge of the first concentrator 23. Since the cross-sectional area of the concentrator cavity 221 gradually decreases from top to bottom, the water flow converges, allowing water flowing out of the concentrator cavity 221 to enter the first water collection cavity 231.
[0049] The first manifold 22 is detachably connected to the water valve 10, facilitating installation, disassembly, or replacement. Preferably, the first manifold 22 is snap-fitted or threadedly connected to the water valve 10.
[0050] The first water collection and distribution unit 23 includes a first inner wall panel 234 and a first outer wall panel 235. The first inner wall panel 234 and the first outer wall panel 235 form a first water collection cavity 231. The first outer wall panel 235 has first water passage holes 232. Water flowing down from above enters the first water collection cavity 231 between the first inner wall panel 234 and the first outer wall panel 235, and then flows out from the multiple first water passage holes 232.
[0051] The first water passage hole 232 extends elongatedly along the axial direction of the first outer wall plate 235, and multiple first water passage holes 232 are spaced apart circumferentially around the first outer wall plate 235. In this embodiment, the first outer wall plate 235 is inverted conical in shape, and the first inner wall plate 234 is cylindrical. The shapes of the first outer wall plate 235 and the first inner wall plate 234 are arranged such that the top of the first water collection cavity 231 is open outward, facilitating the entry of water flowing out of the confluence cavity 221 into the first water collection cavity 231. Specifically, the first inner wall plate 234 is arranged in a ring around the central tube 30.
[0052] The first distribution point 23 not only disperses the water flowing down from above, distributing it evenly, but also prevents resin particles from entering above the resin layer. For example, the diameter of the first water passage 232 is smaller than the diameter of the resin particles.
[0053] The first distribution hub 23 is detachably connected to the first busbar 22, facilitating installation, disassembly, or replacement. Preferably, the first distribution hub 23 is snap-fitted to the first busbar 22, which can be achieved through a snap-fit connection. Alternatively, the first distribution hub 23 can be detached from the first busbar 22 by rotating it relative to the first busbar 22. Exemplarily, the first distribution hub 23 is threadedly connected to the first busbar 22. Exemplarily, the upper end of the first distribution hub 23 is inserted into the mounting cavity 224 on the outer periphery of the first busbar 22. The inner wall of the mounting cavity 224 is provided with a plurality of second locking protrusions 225, and the outer wall of the first distribution hub 23 is provided with a plurality of second locking grooves 233. By rotating the first distribution hub 23, the second locking protrusions 225 can be inserted into the second locking grooves 233. During installation, the upper end of the first distribution hub 23 is inserted into the mounting cavity 224, such that the second locking groove 233 is located on one side of the second locking protrusion 225. By rotating the first distribution hub 23, the second locking protrusion 225 is inserted into the second locking groove 233.
[0054] The first manifold 22 includes a water guide edge 226, which is located below the water inlet 11 and at the top of the manifold 221 to guide water flow into the manifold 221. The water guide edge 226 acts as a buffer for the water entering through the water inlet 11, allowing the water to flow slowly into the manifold 221, thereby achieving a uniform water flow.
[0055] The water guide edge 226 is annular, which facilitates manufacturing and installation. For example, the inner circumference of the water guide edge 226 connects to the confluence cavity 221, and the connection point has an arc-shaped surface to guide the water flow, resulting in a smooth flow. Alternatively, the water guide edge 226 is inclined, and its lower end inserts into the confluence cavity 221 to guide the water flow, resulting in a smooth flow.
[0056] In some embodiments, the first water distribution assembly 20 includes a first confluence member 22, a first distribution 23, and a water distributor 21. The water distributor 21 is disposed on the upper side of the first confluence member 22. The water distributor 21 has a water distribution cavity 211. The bottom surface of the water distribution cavity 211 is provided with a high point and a low point. The high point is directly opposite the water inlet 11. A downwardly inclined water guide surface 212 is provided between the high point and the low point to guide the water flow from the high point to the low point. A plurality of water outlet holes 213 are provided at intervals on the water guide surface 212. The water outlet holes 213 are connected to the confluence cavity 221.
[0057] Water entering from the inlet 11 of the water valve 10 impacts the high point of the water distribution chamber 211 and flows to the low point through the guide surface 212. During the flow in the water distribution chamber 211, the water flows from the outlet 213 on the guide surface 212 to the confluence chamber 221. By setting the guide surface 212, the water flow is more evenly distributed in the water distribution chamber 211, and thus can enter the confluence chamber 221 evenly.
[0058] In this embodiment, the inlet 11 of the water valve 10 is eccentrically positioned relative to the water distributor 21, and the highest point of the bottom surface of the water distribution chamber 211 is located directly below the inlet 11. Specifically, the water distributor 21 has a first axis, and the inlet 11 is eccentrically positioned relative to the first axis. The shape of the inlet 11 can be set according to actual needs; in this embodiment, the inlet 11 extends in an arc shape.
[0059] The water distribution device also includes a central pipe 30, a water valve 10 disposed at the top of the central pipe 30, the top of the central pipe 30 being connected to the outlet 12, a first water distribution assembly 20 sleeved on the upper part of the central pipe 30, a first manifold 22 arranged in a ring around the central pipe 30, a first collector 23 arranged in a ring around the central pipe 30, and a water distribution chamber 211 arranged in a ring around the central pipe 30. The first inner wall plate 234 has a certain height and is sealed to the central pipe 30 to prevent water in the first water collection chamber 231 from overflowing from the top of the first inner wall plate 234.
[0060] Water guide surfaces 212 are provided on both sides of the high point. Water entering from the inlet 11 of the water valve 10 impacts the high point of the water distribution chamber 211 and flows to both sides of the high point and to the low point through the water guide surfaces 212. During the flow in the water distribution chamber 211, the water flows out from the outlet holes 213 on the water guide surfaces 212.
[0061] The interval between the high point and the low point is greater than or equal to 150 degrees and less than or equal to 180 degrees, allowing the water guiding surface 212 to extend a certain length, which is beneficial for the uniform distribution of water flow. Preferably, the interval between the high point and the low point is equal to 180 degrees, and the slope of the water guiding surface 212 set on both sides of the high point can be the same, so that the water flow is uniformly distributed from the high point to both sides.
[0062] Since the high point is directly opposite the inlet 11 of the water valve 10, the water flow rate at the high point is relatively large. Preferably, the flow area of the outlet hole 213 gradually increases along the direction from the high point to the low point, further ensuring that the water flow is evenly distributed in the water distribution chamber 211. Alternatively, the interval between adjacent outlet holes 213 can remain unchanged along the direction from the high point to the low point, while the diameter of each outlet hole 213 increases; or the diameter of each outlet hole 213 can remain unchanged along the direction from the high point to the low point, while the interval between adjacent outlet holes 213 gradually decreases.
[0063] The shape of the water outlet 213 can be set according to actual needs. In this embodiment, the water outlet 213 is an elongated hole that extends radially along the water distributor 21 to ensure a larger water outlet area and make full use of the space of the water distribution chamber 211.
[0064] The water distributor 21 and the water valve 10 are detachably connected for easy installation, disassembly, or replacement. Specifically, the connection can be a snap-fit, threaded connection, or bolt connection. In this embodiment, the water valve 10 is provided with a mounting post 13, which has a threaded hole. The water distributor 21 has a mounting hole 215, and a bolt passes through the mounting hole 215 on the water distributor 21 and is threadedly connected to the threaded hole on the water valve 10.
[0065] The manifold 221 is located below and communicates with the outlet 213, and is located above and communicates with the first water collection chamber 231. Therefore, the manifold 221 connects the outlet 213 and the first water collection chamber 231. The function of the first manifold 22 is to collect the water flowing down from the distributor 21 for easier and more even distribution later.
[0066] The first manifold 22 is detachably connected to the distributor 21, facilitating installation, disassembly, or replacement. Preferably, the first manifold 22 is snapped into the distributor 21 via a snap-fit mechanism. Alternatively, the first manifold 22 can be detached from the distributor 21 by rotating it relative to the distributor 21. Exemplarily, the first collector 23 is threadedly connected to the first manifold 22. Exemplarily, the upper end of the first manifold 22 is inserted into the lower end of the distributor 21. The inner wall of the distributor 21 is provided with a plurality of first locking protrusions 214, and the outer wall of the first manifold 22 is provided with a plurality of first locking grooves 222. During installation, the upper end of the first manifold 22 is inserted into the lower end of the distributor 21, such that the first locking groove 222 is located on one side of the first locking protrusion 214. By rotating the first manifold 22, the first locking protrusion 214 is inserted into the first locking groove 222. During disassembly, the first manifold 22 can be removed from the lower end of the distributor 21 by rotating the first manifold 22 to disengage the first locking protrusion 214 from the first locking groove 222.
[0067] The outer wall of the first manifold 22 is provided with a limiting protrusion 223. When the upper end of the first manifold 22 is inserted into the lower end of the water distributor 21, the limiting protrusion 223 abuts against the lower end of the water distributor 21 to play a limiting role. At this time, rotating the first manifold 22 will allow the first locking protrusion 214 to be inserted into the first locking groove 222, ensuring a stable connection between the first manifold 22 and the water distributor 21.
[0068] Along the top-to-bottom direction, the cross-sectional area of the confluence cavity 221 gradually decreases, that is, the confluence cavity 221 is inverted conical shape. The first confluence element 22 is sleeved on the central tube 30, that is, the central tube 30 is inserted into the confluence cavity 221. The inner wall of the confluence cavity 221 and the outer wall of the central tube 30 form an annular cavity with a gradually decreasing cross-sectional area from top to bottom, which plays a role in converging the water flow and also plays a role in uniformizing the water flow to a certain extent.
[0069] In some embodiments, the first water distribution assembly 20 includes a first manifold 22, a first distribution 23, and a first base 24. In some embodiments, the first water distribution assembly 20 includes a water distributor 21, a first distribution 23, a first manifold 22, and a first base 24.
[0070] The first base 24 has a lifting cavity 241. The lower end of the first distribution 23 is inserted into the lifting cavity 241. The lifting cavity 241 is arranged in a ring around the first distribution 23. Water flowing out of the first water passage 232 overflows from the upper end of the lifting cavity 241. The lower end of the first distribution 23 is inserted into the lifting cavity 241, allowing the water flowing out of the first distribution 23 to enter the lifting cavity 241 and be intercepted by the first base 24. Since the lifting cavity 241 is arranged in a ring around the first distribution 23, the water flow can be evenly distributed in the lifting cavity 241. Finally, the water overflows from the top of the first base 24. The first base 24 plays a role in collecting and equalizing the water flow.
[0071] The lifting cavity 241 is arranged in a ring around the first distribution 23, which can be a continuous ring or a segmented ring. For example, multiple partitions are arranged circumferentially within the lifting cavity 241, dividing the lifting cavity 241 into multiple arc-shaped cavities.
[0072] The first base 24 is disposed on the lower side of the first distribution 23 and is connected to the first distribution 23. The first base 24 and the first distribution 23 are detachably connected for easy installation, disassembly, or replacement. Preferably, the first base 24 and the first distribution 23 are snapped together, which can be done by a snap-fit. Specifically, the first base 24 is provided with a plurality of third snap protrusions 242, and the first distribution 23 is provided with a plurality of third snap slots 236. During installation, the third snap protrusions 242 are inserted into the third snap slots 236 to achieve snap-fit.
[0073] The first base support 24 includes a base plate 243 and a side plate 244. The side plate 244 is arranged in a ring around the base plate 243, and the base plate 243 and the side plate 244 form a lifting cavity 241. A central tube 30 passes through the base plate 243, and a sealing ring can be provided between the central tube 30 and the base plate 243 to prevent water leakage at the bottom of the lifting cavity 241. A third locking protrusion 242 is provided inside the lifting cavity 241 and located on the base plate 243, and a third locking groove 236 is located at the bottom of the first distribution 23.
[0074] The first base support 24 also includes a first reinforcing rib plate 245, which is disposed within the lifting cavity 241 and located on the base plate 243. The first reinforcing rib plate 245 is arranged in a ring shape, and a third locking protrusion 242 is disposed on the first reinforcing rib plate 245. The first base support 24 also includes a second reinforcing rib plate 246, which is disposed within the lifting cavity 241 and located at the junction of the base plate 243 and the side plate 244.
[0075] See Figures 3 to 7 and combined Figures 17 to 19 The water distribution device also includes a second water distribution assembly 40, which is located at the bottom end of the central pipe 30. The second water distribution assembly 40 has a second water collection chamber 41, which is connected to the bottom end of the central pipe 30. Water flows into the second water collection chamber 41 and flows upward along the central pipe 30, and flows out from the top of the central pipe 30 through the outlet 12 of the water valve 10. Figures 5 to 7 The middle arrow indicates a direction of water flow.
[0076] In some embodiments, the second water distribution assembly 40 includes a second distribution 43, which has a second water collection chamber 41 and a plurality of second water passage holes 42 communicating with the second water collection chamber 41. Water flows from the second water passage holes 42 into the second water collection chamber 41 and flows upward along the central pipe 30.
[0077] In this embodiment, the second water distribution assembly 40 includes a second distribution 43 and a second confluence member 44. One end of the second confluence member 44 is connected to the central pipe 30. The second distribution 43 is inserted into the other end of the second confluence member 44 and forms a second water collection cavity 41 with the second confluence member 44. The second distribution 43 has a plurality of second water passage holes 42 that connect the outside world and the second water collection cavity 41.
[0078] The second manifold 44 and the central tube 30 can be threaded together, and the second distribution manifold 43 and the second manifold 44 can be detachably connected for easy installation, disassembly, or replacement. Preferably, the second distribution manifold 43 and the second manifold 44 are snap-fitted together, which can be done by a snap-fit. Alternatively, the second distribution manifold 43 can be detached from the second manifold 44 by rotating it relative to the second manifold 44. Exemplarily, the second distribution manifold 43 and the second manifold 44 are threaded together.

[0079] The second distribution unit 43 includes a second inner wall plate 431 and a second outer wall plate 432 sleeved on the outside of the second inner wall plate 431. The second outer wall plate 432 is connected to the second confluence member 44. The second inner wall plate 431 forms an inner cavity that communicates with the outside. Both the second inner wall plate 431 and the second outer wall plate 432 are provided with second water passage holes 42. The annular cavity formed by the second inner wall plate 431 and the second outer wall plate 432 serves as part of the second water collection cavity 41. Water from the outside can directly reach the second water collection cavity 41 through the second water passage holes 42, or it can reach the second water collection cavity 41 through the inner cavity and the second water passage holes 42, resulting in a large water flow area.
[0080] The second inner wall panel 431 can be provided in one layer or two layers. In this embodiment, the second inner wall panel 431 is provided in two layers, forming an annular cavity between the two layers. Both layers of the second inner wall panel 431 are provided with second water passage holes 42. For ease of description, the two layers of the second inner wall panel 431 are respectively an outer second inner wall panel 4311 and an inner second inner wall panel 4312. The outer second inner wall panel 4311 is arranged around the inside of the second outer wall panel 432, and the inner second inner wall panel 4312 is arranged around the inside of the outer second inner wall panel 4311. The bottom of the outer second inner wall panel 4311 is connected to the bottom of the second outer wall panel 432, and the top of the inner second inner wall panel 4312 is connected to the top of the outer second inner wall panel 4311. The outer second inner wall panel 4311 and the inner second inner wall panel 4312 are connected by a reinforcing plate 433 to increase structural strength.
[0081] This embodiment also provides a water softener, including a resin tank 100 and the aforementioned water distribution device, with a water valve 10 disposed at the opening of the resin tank 100. A resin layer is disposed inside the resin tank 100 on the outside of the water distribution device. Water entering from the inlet 11 of the water valve 10 impacts the high point of the water distribution chamber 211 and flows to the low point via the guide surface 212. During the flow within the water distribution chamber 211, the water flows out from the outlet 213 on the guide surface 212. By providing the guide surface 212, the water flow is more evenly distributed within the water distribution chamber 211, improving resin utilization. Water flows from the distributor 21 into the first manifold 22, which collects the water flowing from the distributor 21. The water then flows into the first distribution 23, which disperses the water collected from the first manifold 22 outwards. The water flowing out of the first distribution 23 is intercepted by the first base 24, and finally overflows from the top of the first base 24. The water flows through the resin layer to the bottom of the resin tank 100. Water then flows from the second water passage 42 into the second water collection chamber 41, flows upwards along the central pipe 30, and flows out from the top of the central pipe 30 through the outlet 12 of the water valve 10.
