Abstract
Description
Technical Field
[0001] This utility model relates to a water distributor and a water softener. Background Technology
[0002] Currently, water softeners generally use softening resin to soften tap water. After a certain amount of tap water passes through, the softening capacity of the resin decreases, requiring regeneration. Regeneration brine flows through a central pipe into the lower distributor. The lower distributor has many fine holes through which the brine flows out, regenerating the softening resin in the resin tank. Currently, the resin tank is limited by the structure of the water softener's valve head, and the inlet size is generally much smaller than the tank's diameter. To allow the lower distributor to fit into the resin tank through the inlet, its size is designed to be relatively small. During regeneration, because the lower distributor is small, the brine flow is mainly concentrated in the central area of the resin tank, resulting in poor regeneration of resin further away from the center. This wastes brine and leads to poor softening performance in the regenerated resin. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a water distributor and a water softener.
[0004] The present invention solves the above-mentioned technical problems through the following technical solution:
[0005] A water distributor includes a water distributor body, a central tube, and a rotatable impeller. The water distributor body has an internal cavity, and a plurality of water distribution holes are provided on the outer surface of the water distributor body. The water distribution holes communicate with the cavity. The lower end of the central tube is connected to the water distributor body, and the inner cavity of the central tube communicates with the cavity. The impeller is installed in the cavity and can be driven by the water flow from the central tube.
[0006] In this design, the lower water distributor has a rotatable impeller installed within the receiving cavity of the distributor body. During regeneration, brine flows into the receiving cavity from the central pipe, driving the impeller to rotate. The rotating impeller agitates the brine, causing it to flow out more evenly from the distribution holes, thus improving the resin regeneration effect. Even if resin particles accumulate at the distribution holes, the agitated water can more easily dissolve the resin, allowing the brine to penetrate deeper into the resin particle layer, resulting in a superior resin regeneration effect.
[0007] Preferably, the lower water distributor further includes an extension pipe, the upper end of which is connected to the lower end of the central pipe, and the lower end of which extends toward the impeller. The extension pipe is used to extend the inner cavity of the central pipe to a position close to the impeller.
[0008] In this design, the extension tube extends the length of the central tube into the cavity and directly above the impeller, increasing the driving force of the brine and correspondingly increasing the rotational speed of the impeller, thereby enhancing the impeller's disturbance effect on the brine.
[0009] Preferably, the impeller includes a shaft and blades. The shaft is arranged vertically, and a plurality of blades are spaced apart on the outer circumferential surface of the shaft along the circumferential direction. One end of the shaft is rotatably connected to the inner wall of the water distributor body, and the other end of the shaft is rotatably connected to the extension pipe.
[0010] In this design, a vertically oriented rotating shaft causes multiple blades to be distributed circumferentially. When the impeller rotates, the blades disperse the brine around the perimeter of the distributor body, improving the brine dispersion effect. By fixing both ends of the rotating shaft to the distributor body and the extension pipe respectively, the impeller can be positioned in the center of the receiving cavity, enhancing the impeller's water agitation effect.
[0011] Preferably, the inner wall of the water distributor body has a first groove, one end of the rotating shaft is embedded in the first groove, the inner wall of the extension tube is connected to a fixing member, the fixing member has a second groove, and the other end of the rotating shaft is embedded in the second groove.
[0012] In this design, the two ends of the rotating shaft are respectively embedded in the first groove and the second groove, which not only ensures the rotation function of the rotating shaft, but also simplifies the fixing structure and makes installation convenient.
[0013] Preferably, the water distributor body includes an upper cover and a water distributor seat, the upper cover and the water distributor seat are welded together, and the upper cover and the water distributor seat form the receiving cavity.
[0014] In this design, the top cover is welded to the water distributor base, which facilitates the separate fabrication of the top cover and the water distributor base, and also makes it easier to install the extension pipe and impeller.
[0015] Preferably, the outer peripheral surface and bottom surface of the water distributor seat are provided with a plurality of water distribution holes, while the upper cover is not provided with water distribution holes.
[0016] In this design, no water distribution holes are provided on the top cover, allowing the brine to flow out from the periphery and bottom of the lower water distributor. This extends the flow path of the brine, ensuring thorough regeneration of the resin at the bottom. If the brine flows out from the top cover, shortening its flow path, the regeneration effect will be poor.
[0017] Preferably, the bottom of the water distributor seat has a convex pointed bottom structure, and the water distribution hole is an elongated hole, with a plurality of the elongated holes arranged radially around the periphery of the impeller.
[0018] In this design, during water softening, the pointed-bottom structure of the water distributor seat facilitates the entry of softened water from the outside into the receiving cavity of the water distributor body, promoting water accumulation. During water softening, the elongated holes enhance water accumulation; during regeneration, the elongated holes facilitate the uniform dispersion of brine into the resin, improving the regeneration effect.
[0019] Preferably, the size of the water distributor body gradually decreases from top to bottom.
[0020] In this solution, the above-mentioned structural design is adopted to form a cone-shaped structure that is larger at the top and smaller at the bottom, thereby improving the water accumulation effect.
[0021] Preferably, the impeller is installed at the bottom of the receiving cavity, and the lower outlet of the central tube is correspondingly arranged with respect to the impeller.
[0022] In this solution, the above-mentioned structural configuration is adopted to allow the brine to flow as far as possible to the bottom of the distributor, and then be agitated by the impeller, thereby improving the regeneration effect of the bottom resin in the resin tank.
[0023] A water softener comprising a water distributor as described above.
[0024] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.
[0025] The significant advantages of this invention are as follows: The lower water distributor incorporates a rotatable impeller within its housing cavity. During regeneration, brine flows into the housing cavity from the central tube, driving the impeller to rotate. This rotation agitates the brine, ensuring a more even flow from the distribution holes and improving resin regeneration. Even when resin particles accumulate at the distribution holes, the agitated brine more easily dissolves them, allowing the brine to penetrate deeper into the resin particle layer, resulting in superior regeneration.

[0045] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.
[0046] like Figures 1-5 As shown, this embodiment discloses a lower water distributor, which includes a water distributor body 1, a central tube 2, and a rotatable impeller 3. The water distributor body 1 has an internal receiving cavity 11, and a plurality of water distribution holes 12 are provided on the outer surface of the water distributor body 1, which communicate with the receiving cavity 11. The lower end of the central tube 2 is connected to the water distributor body 1, and the inner cavity of the central tube 2 communicates with the receiving cavity 11. The impeller 3 is installed in the receiving cavity 11 and can be driven by the water flow from the central tube 2. The lower water distributor has a rotatable impeller 3 installed in the receiving cavity 11 of the water distributor body 1. During regeneration, brine flows into the receiving cavity 11 from the central tube 2, and the brine drives the impeller 3 to rotate. The rotating impeller 3 can agitate the brine and make the brine flow out more evenly from the water distribution holes 12, thereby improving the regeneration effect of the resin. Even when resin particles accumulate at the water distribution holes 12 of the water distributor, the disturbed brine can more easily break up the resin, allowing the brine to penetrate deeper into the resin particle layer, resulting in better resin regeneration.
[0047] like Figure 4 and Figure 5As shown, the lower water distributor also includes an extension pipe 4. The upper end of the extension pipe 4 is connected to the lower end of the central pipe 2, and the lower end of the extension pipe 4 extends towards the impeller 3. The extension pipe 4 is used to extend the inner cavity of the central pipe 2 to a position directly above the impeller 3. The extension pipe 4 extends the length of the central pipe 2 into the interior of the receiving cavity 11 and extends to a position directly above the impeller 3, increasing the driving force of the brine and correspondingly increasing the rotational speed of the impeller 3, thereby improving the agitation effect of the impeller 3 on the brine.
[0048] like Figure 4 and Figure 5 As shown, the impeller 3 includes a shaft 31 and blades 32. The shaft 31 is vertically oriented, and multiple blades 32 are spaced apart on the outer circumferential surface of the shaft 31. One end of the shaft 31 is rotatably connected to the inner wall of the water distributor body 1, and the other end is rotatably connected to the extension pipe 4. The vertically oriented shaft 31 causes the multiple blades 32 to be circumferentially distributed. When the impeller 3 rotates, the blades 32 disperse the brine around the perimeter of the water distributor body 1, improving the dispersion effect of the brine. Fixing both ends of the shaft 31 to the water distributor body 1 and the extension pipe 4 respectively allows the impeller 3 to be positioned in the middle of the receiving cavity 11, improving the water agitation effect of the impeller 3.
[0049] like Figure 4 As shown, the inner wall of the water distributor body 1 has a first groove 13. One end of the rotating shaft 31 is embedded in the first groove 13. The inner wall of the extension tube 4 is connected to a fixing member 41, which has a second groove 411. The other end of the rotating shaft 31 is embedded in the second groove 411. By embedding both ends of the rotating shaft 31 in the first groove 13 and the second groove 411 respectively, the rotation function of the rotating shaft 31 is ensured, the fixing structure is simple, and installation is convenient. Preferably, bearings are installed at both ends of the rotating shaft to reduce friction.
[0050] like Figure 5 As shown, in this embodiment, one end of a plurality of fixing members 41 forms a second groove 411 in the middle of the extension tube 4, and the other end of each fixing member 41 is connected to the inner wall of the extension tube 4. A water passage is formed between adjacent fixing members 41, so that the impeller 3 is located directly below the extension tube 4, thereby improving the disturbance effect of the impeller 3 on the brine.
[0051] like Figures 1-5 As shown, the water distributor body 1 includes an upper cover 14 and a water distributor seat 15, which are welded together. The upper cover 14 and the water distributor seat 15 form a receiving cavity 11. Welding the upper cover 14 and the water distributor seat 15 together facilitates the separate fabrication of the upper cover 14 and the water distributor seat 15, and also facilitates the installation of the extension pipe 4 and the impeller 3.
[0052] like Figure 1As shown, the outer circumferential surface and bottom surface of the water distributor base 15 are provided with a plurality of water distribution holes 12, while the upper cover 14 is not provided with water distribution holes 12. The absence of water distribution holes 12 on the upper cover 14 allows the brine to flow out from the periphery and bottom of the lower water distributor, extending the flow path of the brine and facilitating sufficient regeneration of the resin at the bottom. If the brine flows out from the upper cover 14, shortening the flow path, the regeneration effect will be poor. Preferably, the water distribution holes 12 are elongated holes, which facilitate water accumulation during softening and also facilitate the dispersion of brine during regeneration.
[0053] like Figures 2-4 As shown, the bottom of the water distributor seat 15 has a convex pointed structure, and the water distribution holes 12 are elongated holes, arranged radially around the periphery of the impeller 3. The pointed-bottom structure of the water distributor seat 15 facilitates the entry of softened water from the outside into the receiving cavity 11 of the water distributor body 1 during water softening, promoting water accumulation. The collected water is then discharged from the central pipe 2. Normally, the lower water distributor is placed vertically. The elongated holes facilitate the collection of softened water at different heights during water softening, improving the water accumulation effect. During regeneration, the elongated holes facilitate the dispersion of brine into the resin at different heights, improving the regeneration effect.
[0054] like Figures 1-4 As shown, the size of the water distributor body 1 gradually decreases from top to bottom, forming a cone structure that is larger at the top and smaller at the bottom, which improves the water accumulation effect during water production.
[0055] like Figure 4 As shown, the impeller 3 is installed at the bottom of the receiving cavity 11, and the lower outlet of the central tube 2 is correspondingly set with the impeller 3, so that the brine flows to the bottom of the water distributor body 1 as much as possible, and is then disturbed by the impeller 3, thereby improving the regeneration effect of the bottom resin in the resin tank.
[0056] This embodiment also discloses a water softener, which includes a water distributor as described above.
