[0056] In the related art, a water softener is a device that uses cation exchange resin to remove calcium and magnesium ions in water, reduce the hardness of raw water, and thus soften hard water. Water softeners are currently widely used in industrial and energy systems and have strong equipment attributes. In household use, the soft water produced by water softeners usually has the effects of reducing scale in water heating equipment such as water heaters, wall-mounted boilers, electric water heaters, and bathrooms, avoiding pipe blockage, reducing the attenuation of heat exchange efficiency of heating equipment, reducing the use of detergents, being more friendly to human skin, and making clothes softer and brighter in color after washing.

[0057] like Figures 1 to 6 As shown, the utility model provides a water distributor assembly 100. It should be noted that the water distributor assembly 100 is applied to the tank assembly 10 of the water softening equipment. The tank assembly 10 is filled with resin. The water distributor assembly 100 can evenly distribute the incoming water flow in the tank assembly 10 to ensure that the water flow can evenly flow through the resin layer, thereby improving the efficiency and uniformity of ion exchange in the water. At the same time, the water distributor assembly 10 also prevents the resin particles from flowing out of the tank body 210 with the water, that is, ensures that the resin particles remain in the tank while allowing the water flow to pass through. In addition, the water distributor assembly 10 can also serve as a supporting layer to prevent the resin particles from moving due to the impact of the water flow and maintain the stability and effective working volume of the resin layer.

[0058] Specifically, Figure 1 and Figure 2 As shown, the water distributor assembly 100 includes a disc 110 and a filter screen. The periphery of the disc 110 abuts against the inner wall of the tank assembly 10, so that the inner wall of the tank assembly 10 can radially limit the disc 110 to prevent the disc 110 from radially moving in the tank assembly 10. The disc 110 includes a plurality of vertical ribs 112 and a plurality of circular ribs 111, and the plurality of circular ribs 111 are distributed in concentric circles. A vertical rib 112 is connected between any two adjacent circular ribs 111, and in the radial outward direction of the circular ribs 111, the radius of the circular rib 111 located on the outside is greater than the radius of the circular rib 111 located on the inside.

[0059] In some examples, such as Figure 1As shown, there are 8 vertical ribs 112, and the 8 vertical ribs 112 are evenly arranged in the circumferential direction. Each vertical rib 112 extends in the radial direction of the circular rib 111. There are 4 circular ribs 111, and the four circular ribs 111 are concentrically distributed. And a fan-shaped hole 116 is formed between the circular rib 111 and the vertical rib 112. In the radially outward direction of the disk body 110, the radial widths of the fan-shaped hole 116 are L0, L1, and L2 in sequence, where L0 < L1 < L2. After the water flow enters from the tank assembly 10, it is divided through the fan-shaped hole 116 on the water distributor assembly 100. Among them, in the radially outward direction of the disk body 110, the water flow rate that can pass through the fan-shaped hole 116 becomes larger and larger, allowing more water flow to pass through the outer part of the disk body 110, while relatively reducing the water flow rate passing through the central part of the disk body 110.

[0060] In this way, when the water flow enters the tank assembly 10, after passing through the fan-shaped hole 116 formed by the vertical rib 112 and the circular rib 111, the water flow is guided and dispersed to each area inside the tank body 210, and the water flow can be evenly distributed on the cross-section of the tank body 210. This not only ensures that the water flow can fully contact the resin layer in the tank body 210, thereby maximizing the ion exchange efficiency of the resin, but also makes the flow velocity distribution of the water flow more uniform when passing through the resin layer, reducing the problems of uneven resin utilization or channel flow caused by uneven water flow.

[0061] The filter screen covers the disk body 110, preventing resin particles from penetrating the filter screen while allowing finer broken resin residues to pass through and be discharged. In this way, it can protect the resin particles from being carried out of the tank body 210 by the water flow, and helps to maintain the structural stability of the resin layer, enabling the resin particles to be firmly held in the preset position, thereby extending the effective service life of the resin.

[0062] According to the water distributor assembly 100 of the embodiment of the present utility model, by arranging a plurality of vertical ribs 112 and a plurality of circular ribs 111, and the plurality of circular ribs 111 are concentrically distributed, and a vertical rib 112 is connected between any two adjacent circular ribs 111. In the radially outward direction of the circular rib 111, the distance between any two adjacent circular ribs 111 gradually increases. In this way, in the radially outward direction of the disk body 110, the water flow rate passing through the disk body 110 becomes larger and larger, so that the water flow can fully contact the resin, improving the resin utilization rate.

[0063] Such as Figure 7As shown, in one embodiment of the utility model, the disc body 110 further includes blocking ribs 117, and the blocking ribs 117 are distributed in concentric circles with the circular ribs 111, and the blocking ribs 117 are connected between any two adjacent vertical ribs 112. In this way, the blocking ribs 117 can contain a part of the water flow and prevent the water flow from directly passing through the disc body 110 and entering the resin layer. As a result, the water flow is guided to diffuse along the circumferential direction of the disc body 110, which not only improves the uniformity of the water flow, but also enhances the water separation capacity of the disc body 110. This improvement ensures that the water flow can have a more sufficient contact with the resin, thereby improving the utilization efficiency of the resin and the overall water production. In some embodiments of the utility model, the blocking ribs 117 are arranged between the two outermost circular ribs 111 of the disc body 110, which can further enhance the water separation capacity of the disc body 110.

[0064] like Figure 4 As shown, in one embodiment of the utility model, the disc body 110 further includes a perforated plate 119, which is connected to both the circular ribs 111 and the vertical ribs 112. The perforated plate 119 is provided with a plurality of small holes 1191. In the radially outward direction of the disc body 110, the small holes 1191 are arranged radially, and there is at least one small hole 1191 in the area enclosed by any two adjacent vertical ribs 112 and two adjacent partial circular ribs 111. The small holes 1191 on the perforated plate 119 can further disperse the water flow, so that the water flow is more evenly distributed inside the tank body 210, and the contact area between the water flow and the resin is increased, thereby improving the efficiency of ion exchange. At the same time, the setting of the small holes 1191 can also prevent the resin particles from being moved by the impact of the water flow, and maintain the stability and effective working volume of the resin layer. In addition, the setting of the perforated plate 119 can also enhance the structural stability of the disc body 110, improve the bearing capacity of the disc body 110 itself, and prevent the disc body 110 from being deformed under the impact of the water flow.

[0065] like Figure 4 As shown, in one embodiment of the present invention, a plurality of small holes 1191 are arranged in concentric circles around the center of the disc body 110, further enabling the disc body 110 to evenly distribute water. In addition, by adjusting the number of small holes 1191 and the size of the small holes 1191, the distribution of water can be adjusted, making the water flow more even over the entire cross section, further improving the water distribution effect in the regeneration state, and increasing the water production.

[0066] like Figure 8 , Fig. 9 and Fig.10As shown, in one embodiment of the utility model, the peripheral surface of the disk body 110 is a spherical surface 118, and part of the inner wall of the tank assembly 10 is set to an arc surface with the spherical surface 118, and the spherical surface 118 is in contact with the inner wall of the tank assembly 10, so as to limit the axial direction of the disk body 110 and prevent the disk body 110 from moving in the axial direction, thereby affecting the water distribution performance. At the same time, the fitting position of the disk body 110 and the tank assembly 10 can also be sealed to prevent the resin from leaking from the fitting position of the disk body 110 and the tank assembly 10. In one embodiment of the utility model, at least one vertical rib 112 is provided with a process guide angle. The process guide angle can increase the water diversion effect of the vertical rib 112, thereby improving and guiding the path of the water flow to achieve a more efficient and uniform distribution effect of the water flow. Among them, the process guide angle is formed on the water flow contact surface of the vertical rib 112, and its angle and shape enable the water flow to produce a smooth turning effect when contacting the vertical rib 112. The chamfer not only reduces the direct impact of the water flow on the vertical ribs 112, thereby reducing the mechanical wear on the vertical ribs 112, but also helps to reduce the turbulence and uneven flow velocity distribution that may be generated when the water flows through the resin layer. Of course, the setting method of the process chamfer is not limited to this. In other embodiments of the present invention, at least one round rib 111 is provided with a process chamfer.

[0067] By introducing the process guide angle, the water flow guidance through the vertical ribs 112 and the circular ribs 111 is enhanced, thereby making the water flow distribution on the cross section of the tank body 210 more balanced. In this way, it can be ensured that the water distributor assembly 100 provides a more stable and consistent water flow guidance during the operation of the soft water equipment, further improving the contact efficiency of the resin layer and the uniformity of ion exchange.

[0068] In one embodiment of the utility model, the mesh number of the filter is 80-400 mesh. For example, the mesh number of the filter can be 300 mesh. In this way, the filter can block the resin particles while maintaining the smoothness of the water flow, avoiding water flow blockage or pressure loss caused by too small pores of the filter. During the operation of the water distributor assembly 100, the filter needs to be able to resist the impact of the water flow, maintain structural integrity, and avoid frequent cleaning or replacement due to blockage. Therefore, the filter of 80 to 400 mesh not only meets the requirements of operating efficiency, but also ensures the relatively low maintenance cost of the equipment.

[0069] like Figure 3As shown, in one embodiment of the utility model, the water distributor assembly 100 further includes a central tube 120, which produces a substitution reaction with the resin so that the softened water can flow out of the tank assembly 10 through the central tube 120. The innermost round ribs 111 of the disk body 110 enclose a plug hole 113, and the size and shape of the plug hole 113 match the central tube 120, so that the central tube 120 can be stably inserted into the plug hole 113, reducing the loosening or wear problem of the water distributor assembly 100 caused by water flow impact and mechanical vibration. In addition, the sealing performance of the water distributor assembly 100 is improved, and the risk of leakage caused by mixing of unsoftened water and softened water in the tank assembly 10 is reduced.

[0070] like Figure 3 As shown, in one embodiment of the present invention, in the radially inward direction of the disc body 110, a limiting portion 114 is provided on the inner wall of the plug hole 113, and an abutting portion 121 is provided at the periphery of the central tube 120, and the abutting portion 121 abuts against the limiting portion 114. In this way, the abutting portion 121 can limit the disc body 110 to prevent the disc body 110 from moving in the axial direction under the impact of water flow or mechanical vibration.

[0071] In addition, the coordinated design of the limiting portion 114 and the abutting portion 121 in the utility model can also improve the assembly efficiency of the water distributor assembly 100. Due to the mutual coordination between the limiting portion 114 and the abutting portion 121, the installer can easily identify whether the central tube 120 has been installed in place, and when maintenance or replacement of the central tube 120 is required, it can also be quickly and accurately disassembled and reinstalled.

[0072] like Figure 3 As shown, in one embodiment of the present invention, the abutment portion 121 is an annular boss provided on the outer peripheral wall of the central tube 120. In this way, when the central tube 120 is inserted into the disk body 110, the annular boss can cover the connection gap between the central tube 120 and the disk body 110, and prevent the resin from leaking from the connection gap between the central tube 120 and the disk body 110. Of course, the arrangement of the abutment portion 121 is not limited to a single annular boss. In some other embodiments of the present invention, the abutment portion 121 can be multiple, and the multiple abutment portions 121 are spaced apart along the outer peripheral direction of the central tube 120. This multi-point abutment structure enhances the stability of the central tube 120 in the plug hole 113 and provides sealing points at different positions, thereby further improving the sealing performance and durability of the assembly.

[0073] like Figure 5As shown, the utility model also proposes a tank assembly 10, including a water distributor assembly 100 and a tank body 200. The water distributor assembly 100 is the above-mentioned water distributor assembly 100, and the water distributor assembly 100 is arranged in the tank body 200. Resin is also arranged in the tank body 200, and the tap water is guided to the inside of the tank body 200 through the disk 110 in the water distributor assembly 100. When the tap water passes through the resin layer, the ion exchange effect in the resin will promote the hardness ions in the tap water, such as calcium ions and magnesium ions, to produce a replacement reaction. Through this exchange reaction, the hardness ions in the water are effectively removed, thereby achieving the purpose of softening the water quality. After the softening treatment is completed, the water flow treated by the resin layer will enter the central tube 120 of the tank assembly 10, so that the water flow can stably and smoothly flow out of the tank body 210 from the central tube 120.

[0074] The tank assembly 10 according to the embodiment of the utility model includes the above-mentioned water distributor assembly 100, and thus has the beneficial effects of the above-mentioned water distributor assembly 100, which will not be described in detail here.

[0075] like Figure 6 As shown, in one embodiment of the utility model, a limiting groove 115 is provided on the innermost circular rib 111 of the disk body 110, and a limiting protrusion 221 is provided in the tank body 200. During the assembly process, the limiting protrusion 221 and the limiting groove 115 are interlocked with each other, thereby realizing a fixed connection between the water distributor assembly 100 and the tank body 200.

[0076] Such a fixed connection method not only simplifies the installation process of the water distributor assembly 100 in the tank body 200 and ensures the accuracy of assembly, but also strengthens the connection strength between the water distributor assembly 100 and the tank body 200, making the position of the water distributor assembly 100 in the tank body 210 more stable, reducing the displacement or falling off of the water distributor assembly 100 that may occur during mechanical vibration or transportation, and ensuring the stability of the tank assembly 10 during operation. In addition, the coordinated use of the limiting groove 115 and the limiting protrusion 221 also facilitates the maintenance or replacement of the water distributor assembly 100. When performing maintenance or replacement, the water distributor assembly 100 only needs to be removed from the limiting groove 115.

[0077] like Figure 5 As shown, in one embodiment of the utility model, the tank body 200 includes a tank body 210 and a cover body 220. The resin is arranged in the tank body 210, and the cover body 220 is used to seal the tank body 210 to ensure the airtightness of the tank environment and the protection of the resin. The water distributor assembly 100 is arranged in the tank body 210 to evenly distribute the water flow entering the tank body 210 to promote the ion exchange process between the tap water and the resin.

[0078] The cover body 220 and the tank body 210 are connected by a threaded connection, which simplifies the assembly and disassembly process, while improving the sealing performance of the tank body 210 and preventing the intrusion of external pollutants.

[0079] The limiting protrusion 221 is inside the cover 220, and the water distributor assembly 100 is arranged inside the tank 210. When the cover 220 is threadedly connected to the tank 210, the limiting protrusion 221 cooperates with the corresponding limiting groove 115 on the water distributor assembly 100, thereby realizing the stable positioning of the water distributor assembly 100 in the tank 210. This fixing method ensures that the water distributor assembly 100 can maintain a static position under water pressure, flow and other operating conditions, avoiding displacement or falling off due to vibration or impact, and ensuring the normal operation of the soft water equipment.

[0080] In addition, the design of the limiting protrusion 221 also helps to simplify the manufacturing and assembly process of the tank assembly 10, reducing the possibility of assembly errors. The cooperation between the limiting protrusion 221 and the limiting groove 115 provides an intuitive assembly indication, and the operator can judge whether the assembly is correctly installed. This not only improves assembly efficiency, but also reduces maintenance costs.

[0081] The utility model also provides a water softening device, comprising a tank assembly 10, a water channel component and a control valve. The tank assembly 10 is the above-mentioned tank assembly 10, the water channel component is connected to the tank body 200 of the tank assembly 10, the control valve is connected to the water channel component, and the control valve is used to control the switching of the water channel in the water channel component.

[0082] The water softening device provided by the utility model includes the above-mentioned tank assembly 10, and thus also has the beneficial effects of the above-mentioned tank assembly 10, which will not be described in detail here.

[0083] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
