Description

Technical Field

[0001] This invention relates to the field of water softening equipment technology, and more particularly to water distributor assemblies, tank assemblies, and water softening equipment. Background Technology

[0002] In related technologies, the diameter of the water distributor in water softening equipment is usually small. Therefore, the water distribution area is limited to the area near the radius of the water distributor, which has a limited effect on guiding the water flow. It cannot make the water flow evenly cover the entire cross-section of the resin tank, thus it cannot make the water flow fully contact the resin layer. This results in a low utilization rate of the resin in water production and regeneration, and the resin performance cannot be fully utilized. Summary of the Invention

[0059] 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.

[0060] The following is based on Figures 1 to 6 The water distributor assembly 100 proposed in this invention is introduced.

[0061] like Figures 1 to 3 As shown, the present invention proposes a water distributor assembly 100, including a water distribution component 110, an impeller assembly 120, and a filter screen.

[0062] 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 incoming water flow within 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.

[0063] Specifically, such as Figure 1 and Figure 4 As shown, the water distribution component 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 distribution component 110. This ensures an appropriate gap between the impeller assembly 120 and the water distribution component 110 to promote water flow and reduce the probability of friction or collision between the impeller assembly 120 and the water distribution component 110 during rotation, thereby improving the operating efficiency and durability of the entire water distributor assembly 100. The rotation of the impeller assembly 120 within the receiving cavity 111 can affect the water flow through the water distribution component 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.

[0064] Furthermore, the impeller assembly 120 can optimize the resistance distribution of the water flow, thereby enabling fine-tuning of the water flow dynamics. The rotation of the impeller assembly 120 can effectively guide water to the outermost area of ​​the water distributor, enhancing the inertia of the water flow and promoting the outward diffusion of the water flow. This, in turn, can adjust the water flow distribution within the tank, ensuring that the water flow can make full contact with the top of the tank assembly 10 and the resin layer.

[0065] The filter screen covers the water distribution component 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.

[0066] According to an embodiment of the present invention, the water distributor assembly 100, by providing a rotatable impeller assembly 120 on the water distribution member 110, allows the impeller to optimize the resistance distribution of the water flow, thereby achieving fine-tuning of the water flow dynamics. The rotation of the impeller assembly 120 can effectively guide water to the outermost area of ​​the water distributor, enhancing the inertia of the water flow and promoting the outward diffusion of the water flow. This, in turn, can adjust the water flow distribution within the tank assembly 10, ensuring sufficient contact between the water flow and the resin.

[0067] like Figure 3 and Figure 6 As shown, in one embodiment 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 distribution component 110 and the tank assembly 10 can be ensured, and the water distribution component 110 is prevented from falling off the tank assembly 10 when the water softener is working, thereby affecting the water distribution effect.

[0068] 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 distribution component 110 and the tank assembly 10, ensuring the normal operation of the water softening equipment. The close contact surface between the water distribution component 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 effectiveness of water softening. When cleaning or maintenance of the internal components is required, the presence of the first bending section 1141 makes disassembling and assembling the water distribution component 110 more convenient, and also increases the overall strength of the water distribution component 110, reducing material fatigue and preventing deformation or damage to the water distribution component 110 during long-term use.

[0069] like Figure 2As shown, in one embodiment of the present invention, the impeller assembly 120 includes multiple blades 121, at least one of which has a perforation 123. When the impeller rotates, the perforation 123 can optimize the distribution of water flow by changing the direction and speed of the water flow, making the water flow more evenly distributed within the tank assembly 10. Furthermore, the perforation 123 can also reduce the impeller's rotational resistance; water flow can pass through the perforation 123, thereby reducing the frontal impact of the water flow on the impeller and making the impeller rotate more smoothly. Therefore, the perforation 123 on the impeller allows the impeller assembly 120 to more effectively guide and distribute water flow during rotation, promoting uniform water flow distribution and management, which is highly beneficial for applications requiring precise water flow control.

[0070] like Figure 2 As shown, in one embodiment of the present invention, the blade 121 is a trapezoidal blade 121. When the impeller assembly 120 rotates, the trapezoidal blade 121 can provide more stable flow conditions and higher hydrodynamic efficiency. Especially in applications with high loads or varying flow rates, the trapezoidal blade 121 helps to reduce the generation of eddies and the magnitude of drag, thereby reducing energy consumption.

[0071] like Figure 2 As shown, in one embodiment of the present invention, the impeller assembly 120 further includes a barrel-shaped impeller body 122, which is rotatably connected to the water distribution member 110. 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.

[0072] When the impeller assembly 120 rotates, the blades 121 interact with the water flow, generating rotational power and propelling the water along a predetermined path. The spaced arrangement of the first and second sides helps to create a certain disturbance when the water flows over the blades 121. This disturbance reduces the formation of eddies, improves the flow efficiency and uniformity of the water, and thus optimizes the performance of the entire water distributor. In addition, the barrel-shaped impeller body 122 design makes the blades 121 more securely fixed, and the impeller assembly 120 has higher structural strength, enabling it to withstand pressure changes under different operating conditions, while also facilitating impeller assembly and maintenance.

[0073] like Figure 2As shown, in one embodiment of the present invention, the perforated hole 123 is a circular hole with uniform edges, allowing fluid to pass through stably and improving the smoothness of the water flow. Furthermore, the circular edges also reduce 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.

[0074] In one embodiment of the present invention, the mesh size of the filter screen is 80-400 mesh, for example, 300 mesh. This allows the filter screen to block resin particles while maintaining smooth water flow, avoiding water flow blockage or pressure loss due to excessively small filter screen pores. During the operation of the water distributor assembly 100, the filter screen needs to withstand the impact of water flow, maintain structural integrity, and avoid the need for frequent cleaning or replacement due to blockage. Therefore, a filter screen of 80 to 400 mesh satisfies both the requirements of operating efficiency and the need for relatively low equipment maintenance costs.

[0075] like Figure 3 As shown, in one embodiment of the present invention, the water distribution member 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 distribution member 110 can have a water guiding effect in the lateral and bottom directions. Combined with the impeller assembly 120, the water distribution member 110 can further enhance the guiding effect on the water flow. For the water flow entering the receiving cavity 111, the impeller assembly 120 can generate centrifugal force through its own rotation, thereby guiding the water flow to the perforated portion. The perforated portion further evenly distributes the water flow to the resin layer, ensuring sufficient contact, uniform coverage, and effective utilization of the water flow with the resin layer.

[0076] 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 the hollow portion is formed between any two adjacent connecting ribs 1122. The impeller assembly 120 is connected to the connecting ribs 1122.

[0077] 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. The hollow sections also make the chassis 112 easier to clean and maintain, ensuring the efficient operation of the water distributor.

[0078] like Figure 3 As 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.

[0079] 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 perforated portion 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 perforated portion, 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.

[0080] 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 ribs 1132 are correspondingly connected to the connecting ribs 1122. Since the distance between the support ribs 1132 is equal, the size of the perforated portions 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 distribution member 110. In this way, the water flow can achieve a more uniform distribution when passing through the perforated portions, 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, and reducing deformation and damage caused by uneven load.

[0081] like Figure 1 and Figure 4 As shown, in one embodiment of the present invention, the water distributor assembly 100 further includes a central tube 130, which passes through a water distribution member 110. The water distribution member 110 is located at both ends of the central tube 130, and the central tube 130 passes through an 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.

[0082] like Figure 5 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 distribution member 110. In this way, the water distribution member 110 can be axially limited to prevent the water distribution member 110 from moving in the axial direction.

[0083] like Figure 1 and 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 a water distribution member 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 distribution member 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.

[0084] 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 distribution component 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.

[0085] 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.

[0086] like Figure 4 As 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 distribution member 110 is disposed in the constricted portion 201. The constricted portion 201 can serve as a support point for the water distribution member 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 distribution member 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.

[0087] like Figure 6 As shown, in one embodiment of the present invention, the water distribution component 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. Simultaneously, the fitting design of the first bent section 1141 and the second bent section 202 also improves the sealing performance between the water distributor body 110 and the tank body 200, preventing resin leakage.

[0088] The present invention also proposes a water softening device, including the aforementioned tank assembly 10, water circuit component, and control valve. The water circuit component is connected to the tank body 200 of the tank assembly 10, and the control valve is connected to the water circuit component, the control valve being used to control the switching of the water circuit within the water circuit component.

[0089] The water softening equipment provided by the present invention includes the tank assembly 10 described above, and therefore also has the beneficial effects of the tank assembly 10 described above, which will not be repeated here.

[0090] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions 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 covered within the scope of the claims of the present invention.
