Water distributor assembly and water softener

Abstract

This utility model provides a lower water distributor assembly and a water softener. The lower water distributor assembly includes a lower water distributor with an internal receiving cavity. The surface of the lower water distributor has a plurality of water distribution holes communicating with the receiving cavity. A first baffle plate is circumferentially arranged on the outer peripheral surface of the lower water distributor. The first baffle plate is inclined from top to bottom and outward. At least a portion of the water distribution holes are located below the first baffle plate, or at least a portion of the water distribution holes are located below the first baffle plate. In this lower water distributor assembly, the first baffle plate is circumferentially arranged on the outer peripheral surface of the lower water distributor. The first baffle plate extends downward at an incline. During regeneration, the brine in the lower water distributor flows out from the water distribution holes. Due to the obstruction of the first baffle plate, the brine cannot flow directly upward. Instead, the brine flows from the center to the surrounding edges, allowing it to flow into the resin away from the center, thus improving the resin regeneration effect.

Description

Technical Field

[0001] This utility model relates to a water distributor assembly 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 assembly and a water softener.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A lower water distributor assembly includes a lower water distributor with an internal receiving cavity. The surface of the lower water distributor has a plurality of water distribution holes communicating with the receiving cavity. A first baffle is provided around the outer peripheral surface of the lower water distributor. The first baffle is inclined in a direction from top to bottom and outward. At least a portion of the water distribution holes are located below the first baffle, or at least a portion of the water distribution holes are located below the first baffle.

[0006] In this design, the lower water distributor assembly has a first baffle plate circumferentially mounted on its outer periphery. The first baffle plate extends downwards at an angle. During regeneration, brine flows out of the distribution holes from the lower water distributor. Due to the obstruction of the first baffle plate, the brine cannot flow directly upwards; instead, it flows from the center to the edges, allowing it to reach the resin further from the center, thus improving the resin regeneration effect. Without the first baffle plate, when the brine flows from the lower water distributor into the resin tank, it tends to flow more easily along the outer wall of the lower water distributor and near the central tube, resulting in poor regeneration of the resin further away from the lower water distributor. Specifically, by positioning at least a portion of the distribution holes below the first baffle plate, or at least a portion of the distribution holes below the first baffle plate, a portion of the brine can flow out from below the first baffle plate and then be turbulent by it, allowing the brine to travel a greater distance.

[0007] The shape of the water distribution holes can be customized according to user needs. Preferably, the water distribution holes are elongated holes that extend along the height direction of the lower water distributor. During water production, the elongated holes facilitate water accumulation at different heights of the lower water distributor. During regeneration, the elongated holes can evenly disperse the brine into the resin at different heights, improving the regeneration effect.

[0008] Preferably, there are multiple first baffles, and the multiple first baffles are spaced apart along the height direction of the lower water distributor.

[0009] In this scheme, multiple first baffles are spaced apart along the height direction of the lower water distributor, so that brine at different heights can be dispersed into the resin at a greater distance, thereby improving the dispersion effect of the brine and correspondingly improving the regeneration effect.

[0010] Preferably, the lower water distributor has a structure that is larger at the top and smaller at the bottom along the height direction.

[0011] In this design, the lower water distributor has a structure that is larger at the top and smaller at the bottom along the height direction, forming a cone-shaped structure that is larger at the top and smaller at the bottom. This improves the water accumulation effect during water production and facilitates the dispersion of brine from the center to the surrounding area during regeneration.

[0012] Preferably, a plurality of the first baffles are spaced apart along the height direction of the lower water distributor, and the size of the first baffles gradually increases along the height direction.

[0013] In this scheme, since the inlet size of the resin tank is fixed and the lower water distributor has a structure that is larger at the top and smaller at the bottom, in order to make full use of the inlet space of the resin tank, the size of the first baffle is gradually increased along the height direction. This ensures that the lower water distributor and the first baffle can be put into the resin tank through the inlet, and also improves the baffle effect of the first baffle.

[0014] Preferably, the lower water distributor assembly further includes a central tube, one end of which is connected to the top surface of the lower water distributor, and the inner cavity of the central tube communicates with the receiving cavity.

[0015] In this scheme, the central pipe forms the inlet and outlet channels of the lower water distributor. During water production, the softened water collected by the lower water distributor flows out through the inner cavity of the central pipe. During resin regeneration, brine is injected into the receiving cavity of the lower water distributor through the inner cavity of the central pipe and then dispersed into the resin tank for resin regeneration.

[0016] Preferably, the lower water distributor assembly further includes an extension tube located in the receiving cavity. The upper end of the extension tube is connected to the lower end of the central tube, and the lower end of the extension tube extends downward. A second baffle is provided around the outer circumference of the extension tube, and the second baffle is inclined in a direction from top to bottom and outward.

[0017] In this design, the extension tube extends the length of the central tube into the interior of the receiving cavity, facilitating the delivery of brine to the bottom of the resin tank and improving the regeneration effect. A second baffle is installed on the outer circumference of the extension tube, allowing the brine to flow from the center to the surrounding edges, thus directing the brine into the resin further away from the center and improving the resin regeneration effect.

[0018] Preferably, there are multiple second baffles, which are spaced apart along the height direction of the extension tube.

[0019] In this scheme, multiple second baffles are spaced apart along the height direction of the extension tube, so that brine at different heights can be dispersed into the resin at a greater distance, thereby improving the dispersion effect of the brine and correspondingly improving the regeneration effect.

[0020] Preferably, the second baffle is offset from the first baffle along the height direction, so that the brine can be turbulent at different height positions, thereby improving the turbulence effect of the brine and dispersing the brine to a farther position.

[0021] Preferably, the inner diameter of the extension tube gradually decreases from top to bottom.

[0022] In this design, the inner diameter of the extension tube gradually decreases from top to bottom, which increases the flow rate of the brine, increases the impact force, and facilitates the brine to flow to a more distant location.

[0023] Preferably, the lower water distributor includes an upper cover and a lower water distributor seat, the upper cover and the lower water distributor seat are welded together, and the upper cover and the lower water distributor seat form the receiving cavity.

[0024] In this solution, the upper cover and the lower water distributor base are welded together, which makes it easier to manufacture the upper cover and the lower water distributor base separately and simplifies the manufacturing process.

[0025] A water softener, the water softener further comprising the lower water distributor assembly as described above.

[0026] 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.

[0027] The significant improvement of this invention lies in the following: The lower water distributor assembly has a first baffle plate circumferentially arranged on its outer periphery. This first baffle plate extends downwards at an angle. During regeneration, the brine inside the lower water distributor flows out through the distribution holes. Due to the obstruction of the first baffle plate, the brine cannot flow directly upwards; instead, it flows from the center to the edges, allowing it to reach the resin further from the center, thus improving the resin regeneration effect. Without the first baffle plate, when the brine flows from the lower water distributor into the resin tank, it is more likely to flow along the outer wall of the lower water distributor and near the central tube, resulting in poor regeneration of the resin further away from the lower water distributor. Specifically, by positioning at least a portion of the distribution holes below the first baffle plate, or at least a portion of the distribution holes below the first baffle plate, a portion of the brine can flow out from below the first baffle plate and then be turbulent by it, allowing the brine to travel a greater distance.

[0041] Second spoiler 31 Detailed Implementation

[0042] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0043] like Figures 1-4 As shown, this embodiment discloses a lower water distributor assembly, which includes a lower water distributor 1. The lower water distributor 1 has a receiving cavity 11 inside. The surface of the lower water distributor 1 has a plurality of water distribution holes 12 communicating with the receiving cavity 11. The outer peripheral surface of the lower water distributor 1 is provided with a first baffle plate 13. The first baffle plate 13 is inclined in a direction from top to bottom and outward. At least a portion of the water distribution holes 12 are located below the first baffle plate 13, or at least a portion of the water distribution holes 12 are located below the first baffle plate 13.

[0044] like Figures 1-4 As shown, in this embodiment, the lower water distributor assembly is installed in the resin tank, and resin particles for softening water are placed around the lower water distributor assembly. Since the lower water distributor assembly has a first baffle plate 13 circumferentially arranged on its outer periphery, extending downwards at an angle, during regeneration, the brine in the lower water distributor 1 flows out from the water distribution hole 12. Due to the obstruction of the first baffle plate 13, the brine cannot flow directly upwards; instead, it flows from the center to the edges, allowing it to flow into the resin far from the center, thus improving the resin regeneration effect. Without the first baffle plate 13, when the brine flows from the lower water distributor 1 into the resin tank, it is more likely to flow along the outer wall of the lower water distributor 1 and near the central pipe 2, resulting in poor regeneration of the resin far from the lower water distributor 1. In this configuration, at least a portion of the water distribution holes 12 are located below the first baffle plate 13, or at least a portion of the water distribution holes 12 are located below the first baffle plate 13, ensuring that a portion of the brine can flow out from below the first baffle plate 13 and then be turbulent by the first baffle plate 13, allowing the brine to flow to a greater distance.

[0045] like Figure 3 As shown, the lower water distributor 1 includes an upper cover 14 and a lower water distributor seat 15. The upper cover 14 and the lower water distributor seat 15 are welded together, and the upper cover 14 and the lower water distributor seat 15 form a receiving cavity 11. Welding the upper cover 14 and the lower water distributor seat 15 together makes it easier to manufacture the upper cover 14 and the lower water distributor seat 15 separately, simplifying the manufacturing process.

[0046] The shape of the water distribution hole 12 can be customized according to user needs. For example... Figures 1-4As shown, in this embodiment, the water distribution hole 12 is an elongated hole that extends along the height direction of the lower water distributor 1. During water production, the elongated hole facilitates water accumulation at different heights in the lower water distributor 1. During regeneration, the elongated hole can evenly disperse the brine into the resin at different heights, improving the regeneration effect. If the water distribution hole 12 is an elongated hole, a portion of the elongated hole must be located below the first baffle plate 13 to ensure that the first baffle plate 13 can play a baffle effect. At the same time, the inner diameter of the elongated hole must be smaller than the diameter of the resin particles to prevent resin particles from entering the receiving cavity 11 of the lower water distributor 1. Several elongated water distribution holes 12 are provided on the outer peripheral surface and bottom surface of the lower water distributor base 15.

[0047] like Figures 1-4 As shown, there are multiple first baffles 13, which are spaced apart along the height direction of the lower water distributor 1. This spacing ensures that brine at different heights can be dispersed into the resin at greater distances, improving the dispersion effect and consequently enhancing the regeneration effect. In this embodiment, there are three first baffles 13; however, in other embodiments, the number of first baffles 13 can be set according to user needs.

[0048] The lower water distributor 1 has a structure that is wider at the top and narrower at the bottom along its height. This structure forms a cone-shaped structure, which improves water accumulation during water production and facilitates the dispersion of brine from the center to the surrounding area during regeneration.

[0049] like Figures 1-4 As shown, multiple first baffles 13 are spaced apart along the height direction of the lower water distributor 1, and the size of the first baffles 13 gradually increases along the height direction. Since the inlet size of the resin tank is fixed, and the lower water distributor 1 has a structure that is larger at the top and smaller at the bottom, in order to make full use of the inlet space of the resin tank, the size of the first baffles 13 is gradually increased along the height direction. This ensures that the lower water distributor 1 and the first baffles 13 can be inserted into the resin tank through the inlet, while also improving the turbulence effect of the first baffles 13.

[0050] like Figures 1-4 As shown, the lower water distributor assembly also includes a central tube 2, one end of which is connected to the top surface of the lower water distributor 1. The inner cavity of the central tube 2 communicates with the receiving cavity 11. The central tube 2 forms the inlet and outlet channels of the lower water distributor 1. During water production, the softened water collected by the lower water distributor 1 flows out through the inner cavity of the central tube 2. During resin regeneration, brine is injected into the receiving cavity 11 of the lower water distributor 1 through the inner cavity of the central tube 2, and then dispersed into the resin tank for resin regeneration.

[0051] like Figure 4As shown, the lower water distributor assembly also includes an extension pipe 3, located in the receiving cavity 11. The upper end of the extension pipe 3 is connected to the lower end of the central pipe 2, and the lower end of the extension pipe 3 extends downward. A second baffle 31 is arranged around the outer circumference of the extension pipe 3, and the second baffle 31 is inclined in a direction from top to bottom and outward. The extension pipe 3 extends the length of the central pipe 2 into the receiving cavity 11, facilitating the delivery of brine to the bottom of the resin tank and improving the regeneration effect. The second baffle 31 on the outer circumference of the extension pipe 3 facilitates the flow of brine from the center to the surrounding edges, allowing the brine to flow into the resin away from the center, thus improving the resin regeneration effect.

[0052] There are multiple second baffles 31, which are spaced apart along the height direction of the extension pipe 3. This spacing ensures that brine at different heights can be dispersed into the resin at greater distances, improving the dispersion effect and consequently enhancing the regeneration effect. In this embodiment, three second baffles 31 are used; however, in other embodiments, the number of second baffles 31 can be set according to user needs.

[0053] like Figure 4 As shown, the second baffle 31 is offset from the first baffle 13 along the height direction, so that the brine can be turbulent at different height positions, thereby improving the turbulence effect of the brine and dispersing the brine to a farther position.

[0054] like Figure 4 As shown, the inner diameter of the extension tube 3 gradually decreases from top to bottom. This gradual decrease in the inner diameter of the extension tube 3 accelerates the flow rate of the brine, increases the impact force, and facilitates the brine flowing to a farther location. Because the inner diameter of the water distributor seat 15 is larger at the top and smaller at the bottom, gradually decreasing the inner diameter of the extension tube 3 from top to bottom allows for the placement of a larger second flow-dispersing plate 31 within the receiving cavity 11, thereby improving the flow-dispersing effect.

[0055] This embodiment also discloses a water softener, which further includes the lower water distributor assembly as described above.
