[0061] In related technologies, water softening equipment is a device that uses cation exchange resin to remove calcium and magnesium ions from water, reducing the hardness of the raw water and thus softening hard water. Water softening equipment is currently widely used in industrial and energy systems, exhibiting strong equipment-related characteristics. In household use, the soft water produced by water softening equipment typically reduces limescale buildup in water heating equipment such as water heaters, wall-mounted boilers, and electric water heaters, as well as in bathrooms; prevents pipe blockage; reduces the attenuation of heat exchange efficiency in heating equipment; reduces detergent usage; is gentler on human skin; and leaves clothes softer and more vibrant after washing.

[0062] The following is based on Figures 1 to 6 This invention introduces the water distributor assembly proposed in this paper.

[0063] It should be noted that the water distributor assembly 100 provided by this invention is applied within a water softening device. The water softening device's tank assembly 10 contains resin and the water distributor assembly 100. The water distributor assembly 100 can evenly distribute the water flow entering the tank assembly 10, ensuring that the water flow can evenly pass through the resin layer, thereby improving the efficiency and uniformity of ion exchange in the water. Simultaneously, the water distributor assembly 100 also prevents resin particles from flowing out of the tank with the water, ensuring that the resin particles remain inside the tank while allowing water flow. Furthermore, the water distributor assembly 100 can also function as a support layer, preventing resin particles from moving due to water flow impact, maintaining the stability and effective working volume of the resin layer.

[0064] like Figures 1 to 3 As shown, the present invention proposes a water distributor assembly 100, including a water distributor body 110, a central tube 130, an impeller assembly 120, and a filter screen. Specifically, as... Figure 1 and Figure 4 As shown, the water distributor body 110 has a receiving cavity 111. The wall of the receiving cavity 111 includes a connected mounting section 114 and a fixing section 115, and the thickness of the mounting section 114 is less than the thickness of the fixing section 115. An impeller assembly 120 is disposed within the receiving cavity 111 and is rotatable relative to the water distributor body 110. This ensures an appropriate gap between the impeller assembly 120 and the water distributor body 110 to promote water flow and reduce the probability of friction or collision between the impeller assembly 120 and the water distributor body 110 during rotation, thereby improving the overall operating efficiency and durability of the water distributor assembly 100. The rotation of the impeller assembly 120 within the receiving cavity 111 can affect the water flow through the water distributor body 110. By adjusting the rotation speed and direction of the impeller assembly 120, the speed and direction of the water flow can be precisely controlled to achieve the desired water distribution effect.

[0065] A central tube 130 passes through the water distributor body 110. The impeller assembly 120 has multiple blades 121 for guiding water flow, and the impeller assembly 120 is integrally formed with the central tube 130. Thus, the impeller assembly 120 can guide the water flowing through the water distributor body 110. When the water flow collides with the blades 121, it is forced to change direction according to the angle and shape of the blades 121, allowing the water flow to be guided along the blades 121 to the outer periphery of the water distributor body 110, promoting the outward diffusion of the water flow. This adjusts the water flow distribution within the tank, increases the guiding area of ​​the water distributor assembly 100, and ensures sufficient contact between the water flow and the resin. The space formed between the blades 121 can serve as a flow channel, guiding the water flow along a fixed path. Of course, the installation method of the impeller assembly 120 and the central tube 130 is not limited to this; in other examples, the impeller assembly 120 and the central tube 130 can also be heat-fused together.

[0066] The filter screen covers the water distributor body 110, preventing resin particles from penetrating the filter screen while allowing finer resin residue to pass through and be discharged. This protects the resin particles from being carried out of the tank assembly 10 by the water flow and helps maintain the structural stability of the resin layer, so that the resin particles can be firmly held in the preset position, thereby extending the effective service life of the resin.

[0067] According to an embodiment of the present invention, the water distributor assembly 100 is provided with an impeller assembly 120, which is fixedly connected to the central tube 130. In this way, the impeller assembly 120 can guide the water flowing through the water distributor body 110, so that the water flow can be guided along the blades 121 to the outer periphery of the water distributor body 110, promoting the outward diffusion of the water flow. This can adjust the water flow distribution in the tank, increase the guiding area of ​​the water distributor assembly 100 for the water flow, and ensure sufficient contact between the water flow and the resin.

[0068] like Figure 2 As shown, in some embodiments of the present invention, at least one of the multiple blades 121 is provided with a perforation 123. The perforation 123 allows the water flow to be more evenly dispersed when passing through the blade 121, which helps to improve the water flow distribution pattern, thereby forming a more uniform water flow distribution on the outer side of the water distributor body 110. When the water flow suddenly changes direction or speed, water hammer may occur, which is a pressure fluctuation caused by water flow impact, which may damage the blade 121. The perforation 123 can alleviate this phenomenon, as it can provide a buffer space for changes in the direction of the water flow.

[0069] like Figure 2 As shown, in some embodiments of the present invention, the blade 121 is a trapezoidal blade 121. The trapezoidal blade 121 can provide more stable flow conditions and higher hydrodynamic efficiency for water flow.

[0070] like Figure 2 As shown, in some embodiments of the present invention, the impeller assembly 120 further includes a barrel-shaped impeller body 122, which is fixedly connected to the central tube 130. Multiple blades 121 are disposed on the outer peripheral wall of the impeller body 122. The width direction of the blades 121 extends along the circumferential direction of the impeller body 122. Two sides of the blades 121 in their width direction are designated as a first side and a second side, which are spaced apart along the axial direction of the impeller body 122. Thus, the blades 121 have an outwardly expanding shape, causing the water flow to spread out as it passes through the blades 121, resulting in a more uniform distribution over a wider area. The inclined design of the blades 121 allows the water flow to generate a rotational flow effect as it passes through the impeller assembly 120, thereby promoting a uniform water flow distribution.

[0071] like Figure 2 As shown, in some embodiments of the present invention, the perforated hole 123 is a circular hole. The uniform edge of the circular hole allows for stable fluid flow, improving the smoothness of the water flow. Furthermore, the circular edge reduces the impact and wear of the water flow on the blade 121, extending its service life. Moreover, circular holes are easier to process than other shapes, ensuring processing accuracy and repeatability. Of course, the perforated hole 123 is not limited to this. In other embodiments of the present invention, the perforated hole 123 can also be an elliptical hole. Alternatively, in other embodiments of the present invention, the perforated hole 123 can also be a polygonal hole.

[0072] like Figure 3 and Figure 6 As shown, in some embodiments of the present invention, the mounting section 114 is attached to the wall of the tank assembly 10, and the free end of the mounting section 114 has a first bent section 1141, which overlaps with the opening of the tank assembly 10. In this way, the stability of the installation between the water distributor body 110 and the tank assembly 10 can be guaranteed, and the water distributor body 110 can be prevented from falling off the tank assembly 10 when the water softener is working, thereby affecting the water distribution effect.

[0073] Furthermore, the first bending section 1141 overlaps with the opening of the tank assembly 10, which helps to form a better sealing effect, thereby preventing water or other substances from leaking at the connection between the water distributor body 110 and the tank assembly 10, ensuring the normal operation of the water softening equipment. The close contact surface between the water distributor body 110 and the tank assembly 10 reduces dead zones in the water flow, allowing the water flow to be more evenly distributed throughout the entire tank assembly 10, thus improving the efficiency and effect of water softening. When cleaning or maintenance of internal components is required, the presence of the first bending section 1141 makes disassembling and assembling the water distributor body 110 more convenient, and also increases the overall strength of the water distributor body 110, reducing material fatigue and preventing deformation or damage to the water distributor body 110 during long-term use.

[0074] like Figure 3 As shown, in one embodiment of the present invention, the water distributor body 110 includes a chassis 112 and a surrounding plate 113. The chassis 112 is connected to the impeller assembly 120, and the surrounding plate 113 is disposed on the outer periphery of the chassis 112, defining a receiving cavity 111 together with the chassis 112. At least one of the surrounding plate 113 and the chassis 112 has a perforated portion. Thus, the water distributor body 110 can have a water guiding effect in the lateral and bottom directions. Combined with the impeller assembly 120, the water distributor body 110 can further enhance the guiding effect on the water flow. For water flowing into the receiving cavity 111, the impeller assembly 120 guides the water flow to the perforated portion through its blades 121. The perforated portion further distributes the water flow evenly to the resin layer, ensuring sufficient contact, uniform coverage, and effective utilization of the water flow with the resin layer.

[0075] like Figure 3 As shown, in one embodiment of the present invention, the chassis 112 includes annular ribs 1121 and multiple connecting ribs 1122. The annular ribs 1121 are connected to the surrounding plate 113, providing structural support and defining the outer edge of the receiving cavity 111. The multiple connecting ribs 1122 are arranged radially along the annular ribs 1121, and a hollow portion is formed between any two adjacent connecting ribs 1122. The impeller assembly 120 is connected to the connecting ribs 1122.

[0076] The annular ribs 1121 and connecting ribs 1122 enhance the deformation resistance and load-bearing capacity of the chassis 112, while also reducing its overall weight. Furthermore, the hollow sections formed by the connecting ribs 1122 serve as multiple water flow guiding channels, allowing for better control of the water flow direction and optimizing its distribution beneath the chassis 112. Additionally, the hollow sections make the chassis 112 easier to clean and maintain, ensuring the efficient operation of the water distributor.

[0077] like Figure 3As shown, in one embodiment of the present invention, the included angle formed between any two adjacent connecting ribs 1122 is equal. This allows for a more uniform and distributed water flow through the perforated portion, resulting in a smooth and consistent water flow pattern within the water distributor's operating area. Furthermore, the uniformly distributed connecting ribs 1122 provide balanced support, thereby enhancing the structural stability and durability of the entire chassis 112 and reducing deformation and damage caused by uneven load distribution.

[0078] like Figure 3 As shown, in one embodiment of the present invention, the enclosure 113 includes an annular ring 1131, and multiple support ribs 1132 are spaced apart on the annular ring 1131. A perforation is formed between any two adjacent support ribs 1132. The thickness of the support ribs 1132 is greater than the thickness of the annular ring 1131. This enhances the structural strength of the support ribs 1132, preventing them from being broken by water flow when passing through the perforation, thus affecting the water distribution effect. Furthermore, because the structure of the support ribs 1132 becomes more robust, the entire enclosure 113 is more stable under counterweight or external force, reducing the possibility of deformation and damage. At least one support rib 1132 is connected to the chassis 112, further enhancing the structural strength between the enclosure 113 and the chassis 112, and further guiding the water flow. In addition, the support ribs 1132 can also reduce the weight of the enclosure 113.

[0079] like Figure 3 As shown, in one embodiment of the present invention, the distance between any two adjacent support ribs 1132 is equal, and the support frame 1132 is connected to the connecting rib 1122 in a one-to-one correspondence. Since the distance between the support ribs 1132 is equal, the size of the perforated portion is also equal, which helps to achieve uniform water flow distribution, ensuring that the water flow can evenly cover the required coverage area when leaving the water distributor body 110. In this way, the water flow can achieve a more uniform distribution when passing through the perforated portion, thereby forming a stable and consistent water flow pattern within the water distributor's working area. Furthermore, the equally spaced support ribs 1132 can provide a balanced force distribution on the enclosure 113, avoiding structural deformation or stress concentration caused by uneven forces, enhancing the overall structural stability of the water distributor assembly 100, and reducing deformation and damage caused by uneven load.

[0080] like Figure 1 and Figure 4As shown, in one embodiment of the present invention, the water distributor assembly 100 further includes a central tube 130, which passes through the water distributor body 110. The water distributor body 110 is located at both ends of the central tube 130, and the central tube 130 passes through the impeller assembly 120, allowing the impeller assembly 120 to rotate around the central tube 130. In this way, the central tube 130 provides a fixed center of rotation for the impeller assembly 120, ensuring the stability of the impeller assembly 120's rotation process, thereby improving the operating efficiency and reliability of the impeller assembly 120. Furthermore, the central tube 130 provides support inside the impeller assembly 120, reducing deformation and damage to the impeller assembly 120 caused by water flow impact or external forces.

[0081] like Figure 4 As shown, in one embodiment of the present invention, the wall of the central tube 130 is provided with a protrusion 131, which abuts against the water distributor body 110. In this way, the water distributor body 110 can be axially limited to prevent the water distributor body 110 from moving in the axial direction.

[0082] like Figure 4 As shown, in one embodiment of the invention, the protrusion 131 is an annular boss. Due to its symmetry, the annular boss can provide a uniform stress distribution on the contact surface. This helps prevent stress concentration, thereby reducing the possibility of material fatigue or fracture. In the connection between the central tube 130 and the water distributor body 110, the annular boss can serve as a positioning element to ensure that the central tube 130 and the water distributor body 110 are correctly aligned during installation, reducing installation errors.

[0083] Of course, the structural configuration of the central tube 130 and the water distributor body 110 is not limited to this. In other embodiments of the present invention, the wall of the central tube 130 is provided with a limiting groove, and the water distributor body 110 is provided with a hook structure, the free end of which engages in the limiting groove. When the water distributor body 110 is pushed from bottom to top to the top of the central tube 130, the hook structure inserts into the limiting groove, thereby axially limiting the water distributor body 110 on the central tube 130. The hook structure can be an elastic claw, which can easily spring open and insert into the limiting groove, and can also easily pop out of the groove, facilitating the quick installation and disassembly of the water distributor body 110 and the central tube 130. Furthermore, the elastic claw has a certain degree of flexibility, which can reduce damage to the water distributor body 110 and the central tube 130 during installation or disassembly, extending the service life of the equipment.

[0084] In one embodiment of the invention, the mesh size of the filter screen is 80-400 mesh. For example, the mesh size of the filter screen can be 100 mesh, so that the filter screen can block resin particles while maintaining the smoothness of water flow, avoiding water flow blockage or pressure loss caused by the filter screen pores being too small. During the operation of the water distributor assembly 100, the filter screen needs to be able to resist the impact of water flow, maintain structural integrity, and avoid the need for frequent cleaning or replacement due to blockage.

[0085] like Figure 4 As shown, the present invention also provides a tank assembly 10, including the aforementioned water distributor assembly 100 and a tank body 200, with the water distributor body 110 disposed within the tank body 200. It should be noted that the tank assembly 10 can perform forward and reverse washing. When forward washing is required, i.e., when softening tap water, tap water enters the tank body 200 from the water distributor body 110 and comes into contact with the resin layer within the tank body 200. At this time, hardness ions (such as calcium and magnesium) in the water undergo a displacement reaction with sodium ions on the resin, thereby "softening" the water quality, i.e., reducing the content of hardness ions in the water. The resin layer, as an ion exchange medium, captures hardness ions and releases sodium ions through this process, thereby achieving the purpose of softening the water quality. The water treated by the resin layer is then guided out of the tank through the central pipe 130 and supplied to the user.

[0086] Backwashing refers to the process of regenerating and cleaning the resin layer by changing the direction of water flow. When backwashing is required for tank assembly 10, water flows from the central pipe 130 to the bottom of the tank body 200, is distributed to the resin layer by the water distributor body 110, and finally exits from the tank body 200. During backwashing, a high-concentration brine, i.e., a regenerant, is typically used, flowing through the tank body 200. This process replaces the hardness ions accumulated in the resin layer, and sodium ions in the regenerant reoccupy the exchange sites in the resin layer. At the same time, the backwash water flow can also remove solid particles and other deposits from the resin layer, cleaning the resin layer and restoring its water softening function.

[0087] The tank assembly 10 provided according to the present invention includes the water distributor assembly 100 described above, and therefore also has the beneficial effects of the water distributor assembly 100 described above, which will not be repeated here.

[0088] like Figure 4As shown, in one embodiment of the present invention, the tank body 200 has a constricted portion 201, and the opening of the tank body 200 communicates with the constricted portion 201. A portion of the structure of the water distributor body 110 is disposed in the constricted portion 201. The constricted portion 201 can serve as a support point for the water distributor body 110, ensuring its stable position within the tank body 200 and preventing displacement or jolting during water flow impact or operation. Simultaneously, the constricted portion 201 facilitates water flow collection and distribution, allowing it to act as a water flow guide structure, promoting uniform water distribution onto the resin layer within the tank body 200 and improving treatment efficiency. The design of the constricted portion 201 also helps achieve a better sealing effect between the water distributor body 110 and the tank body 200, preventing water and particles from leaking from the joint and ensuring the overall effectiveness of the water treatment process.

[0089] like Figure 6 As shown, in one embodiment of the present invention, the water distributor body 110 has a first bent section 1141, and the wall surface at the opening of the tank body 200 has a second bent section 202, with the first bent section 1141 and the second bent section 202 fitting together. This enhances the connection stability between the water distributor body 110 and the tank body 200, preventing the water distributor body 110 from detaching from the tank body 200 due to force during use.
