Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0036] It should also be noted that in the XYZ coordinate system provided in this article, the positive direction of the X-axis represents the left, the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0037] Nowadays, the resin tank in household water softening equipment is a standard component. The inlet of the resin tank usually adopts a narrow-mouth design. Because the small opening at the top of the resin tank has a certain limitation on the size of the water distributor, smaller diameter water distributors are usually used on the market. The water distribution area is limited to a small area near the water distributor and cannot cover the entire cross-section of the resin tank. This results in a low utilization rate of water production and regenerated resin, and the resin tank cannot be fully utilized.

[0038] In related technologies, a novel resin tank has been designed with an installation port that covers the entire cross-section of the resin tank. This allows the water distributor to be designed to have a cross-sectional area comparable to that of the resin tank, enabling the water distributor to completely cover the tank's cross-section and maximizing the utilization of resin properties. However, as the water distribution area of ​​the water distributor increases, the impact force of the water flow on it also increases. Furthermore, the water distributor in related technologies has relatively low structural strength and is prone to deformation under the impact of water flow.

[0039] To solve the aforementioned technical problems, firstly, please refer to... Figures 1 to 4 This application discloses a water distributor assembly 011, which includes a disc body 0111. The disc body 0111 includes an inner ring body 011a, an outer ring body 011b, multiple annular ribs 011c, and multiple connecting ribs 011d. The outer ring body 011b is arranged around the periphery of the inner ring body 011a, and a water flow channel is formed between the outer ring body 011b and the inner ring body 011a, allowing water to flow between them. The multiple connecting ribs 011d are located between the inner ring body 011a and the outer ring body 011b, and both ends of the connecting ribs 011d are respectively connected to the inner ring body 011a. The inner ring body 011a and the outer ring body 011b are connected. Multiple connecting ribs 011d are arranged at intervals along the periphery of the inner ring body 011a. The connecting ribs 011d can be intersected and connected with the annular ribs 011c. The multiple annular ribs 011c can be located between the inner ring body 011a and the outer ring body 011b. The multiple annular ribs 011c are distributed at intervals along the radial direction of the outer ring body 011b. The multiple annular ribs 011c include a first rib 0102 and a second rib 0103. The width of the first rib 0102 along the radial direction of the outer ring body 011b is greater than the width of the second rib 0103 along the radial direction of the outer ring body 011b.

[0040] Understandably, the disc 0111 of the water distributor assembly 011 is applied to the tank of the resin tank 010, which contains resin that can be layered. The water distributor assembly 011 can evenly distribute the water flowing into the tank, ensuring that the water can flow evenly through the resin layer, thereby improving the efficiency and uniformity of ion exchange between the water and the resin layer.

[0041] The inner ring body 011a and the outer ring body 011b are the basic components constituting the disc body 0111. The outer ring body 011b surrounds the outer periphery of the inner ring body 011a, and there is a gap cavity between the outer ring body 011b and the inner ring body 011a. This gap cavity can form a water flow channel, so that the water flowing towards the disc body 0111 can flow through the water flow channel.

[0042] Multiple connecting ribs 011d can be located between the inner ring body 011a and the outer ring body 011b, and one end of each connecting rib 011d can be connected to the outer side wall of the inner ring body 011a, and the other end of each connecting rib 011d can be connected to the inner side wall of the outer ring body 011b. This allows the connecting ribs 011d to connect the inner ring body 011a and the outer ring body 011b together. Furthermore, the multiple connecting ribs 011d can be arranged at intervals along the periphery of the inner ring body 011a, thereby connecting the outer side wall of the inner ring body 011a and the inner side wall of the outer ring body 011b together, which can increase the structural strength of the disc body 0111.

[0043] Multiple annular ribs 011c are located between the inner ring body 011a and the outer ring body 011b, and the multiple annular ribs 011c can be distributed sequentially at intervals along the radial direction of the outer ring body 011b. Figure 1 The X-axis and Y-axis directions in the diagram both represent the radial direction of the outer ring body 011b, allowing multiple annular ribs 011c to be evenly distributed within the water flow channel. Each connecting rib 011d intersects and connects with multiple annular ribs 011c, enabling the connecting ribs 011d to connect multiple annular ribs 011c to the inner ring body 011a and the outer ring body 011b, thereby increasing the structural strength of the disc body 0111. Furthermore, the multiple connecting ribs 011d and multiple annular ribs 011c can divide the water flow channel into multiple sub-channels, enabling the water flow towards the disc body 0111 to be evenly distributed, thus ensuring that the water flowing into the resin tank 010 is evenly distributed.

[0044] It should be noted that among the multiple annular ribs 011c, a portion of the annular ribs 011c are first ribs 0102, and another portion are second ribs 0103. Both the first ribs 0102 and the second ribs 0103 are annular structures. The difference between the first ribs 0102 and the second ribs 0103 is that the radial width of the first rib 0102 along the outer ring body 011b is greater than that of the second rib 0103 along the outer ring body 011b. This makes the structural strength of the first rib 0102 greater than that of the second rib 0103. In other words, the first rib 0102 is less prone to deformation than the second rib 0103. Therefore, by setting the second rib 0103, the structural strength of the disc body 0111 can be further increased, thereby increasing the rigidity of the water distributor assembly 011. Even if the water distribution area of ​​the water distributor assembly 011 increases, the water distributor assembly 011 is less prone to deformation under the impact of water flow.

[0045] Please see Figure 1 and Figure 2 In some embodiments, the first rib 0102 is located in the middle of the disc body 0111.

[0046] It should be noted that the middle position of the disc 0111 refers to the central region between the inner ring 011a and the outer ring 011b. More specifically, the distance between the first rib 0102 and the inner ring 011a is equal to or approximately equal to the distance between the first rib 0102 and the outer ring 011b, so that the first rib 0102 can provide support for the middle position of the disc 0111, thereby preventing deformation of the middle position of the disc 0111 and further preventing deformation of the disc 0111.

[0047] Please see Figure 2 In some embodiments, the disc body 0111 includes four second ribs 0103, with two adjacent second ribs 0103 forming a group, and a first rib 0102 located between two groups of second ribs 0103.

[0048] In this embodiment, the disc body 0111 can include five annular ribs 011c, four of which are second ribs 0103, and the remaining one is a first rib 0102. The four second ribs 0103 can be distributed sequentially at intervals along the radial direction of the outer annular body 011b, and in adjacent pairs of second ribs 0103, one second rib 0103 is arranged around the outer periphery of the other second rib 0103. The innermost second rib 0103 in 03 can be connected to the outer wall of the inner ring 011a. The outermost second rib 0103 among the four second ribs 0103 can be connected to the inner wall of the outer ring 011b. Two adjacent second ribs 0103 form a group. The first rib 0102 can be located between two groups of second ribs 0103, so that the first rib 0102 can be located in the middle position of the disc 0111, further increasing the structural strength of the disc 0111.

[0049] In other embodiments, the disc body 0111 may also include other numbers of annular ribs 011c, and the number of first ribs 0102 and second ribs 0103 among the multiple annular ribs 011c can be set according to actual conditions, and is not limited here.

[0050] Please see Figure 1 and Figure 2 In some embodiments, multiple second ribs 0103 are provided, one of which is an annular rib 010a. Along the axial direction of the outer ring, the distance between the top surface of the annular rib 010a and the top surface of the connecting rib 011d is greater than the distance between the top surface of the other second ribs 0103 and the top surface of the connecting rib 011d.

[0051] It is understandable that the bottom surfaces of multiple second ribs 0103 can be disposed on the same plane, and one of the multiple second ribs 0103 is an annular rib 010a. The vertical distance between the top surface of the annular rib 010a and the top surface of the connecting rib 011d is a first distance, and the vertical distance between the top surface of the other second ribs 0103 and the top surface of the connecting rib 011d is a second distance. The first distance is greater than the second distance, so that the annular rib 010a protrudes relative to the other second ribs 0103 along the axial direction of the outer ring body 011b. Figure 1The Z-axis direction in the figure represents the axial direction of the outer ring body 011b. Thus, the annular rib 010a can separate the water flow into the resin tank 010, so that part of the water flow flows into the interior of the annular rib 010a and the other part flows into the exterior of the annular rib 010a. This improves the radial water distribution uniformity of the water flow into the resin tank 010, which can improve the water distribution effect of the water distributor assembly 011 and thus improve the water production efficiency of the resin tank 010.

[0052] In some embodiments, the water distributor assembly 011 further includes a filter screen (not shown) located on one side of the outer ring body 011b along its axial direction and covering the disc body 0111.

[0053] Optionally, the filter screen and disc 0111 can be arranged along the axial direction of the outer ring 011b, and the filter screen covers the disc 0111 so that the filter screen can also cover the cross-section of the resin tank 010. Thus, the filter screen can be used to prevent resin particles from leaking out of the disc 0111, and the filter screen can also provide additional filtration effect to ensure the purity of the output water.

[0054] In some embodiments, the mesh number of the filter screen is n, where n satisfies: 400 mesh ≥ n ≥ 80 mesh. For example, the mesh number n of the filter screen can be 100 mesh, so that the filter screen can block resin particles while maintaining the smoothness of water flow and avoid water flow blockage or pressure loss caused by the filter screen pores being too small. Of course, the filter screen pores cannot be too large either, as the filter screen pores cannot block resin particles if they are too large.

[0055] Please see Figure 1 and Figure 2 In some embodiments, the centers of multiple annular ribs 011c are located on the same central axis.

[0056] Specifically, the center of the annular rib 011c can refer to the center point of the inner ring surface of the annular rib 011c. The centers of multiple annular ribs 011c are located on the same central axis, so that multiple annular ribs 011c can be evenly distributed on the disc body 0111. Multiple annular ribs 011c can more effectively disperse and resist the impact force of water flow, thereby improving the overall structural strength of the disc body 0111 and making the disc body 0111 less prone to deformation.

[0057] Please see Figure 1 and Figure 2 In some embodiments, the annular rib 011c is a circular rib, and multiple circular ribs are distributed in concentric circles.

[0058] It is understandable that the circular rib 011c is a circular rib, meaning that the overall shape of the circular rib 011c is circular, and the projection of the inner ring surface of the circular rib 011c along the axial direction of the circular rib 011c is circular. Multiple circular ribs are distributed in concentric circles, which allows multiple circular ribs to be more evenly distributed on the disc body 0111, and can also more evenly distribute the water flow.

[0059] Please see Figures 1 to 4 In some embodiments, the water distributor assembly 011 further includes a central tube 0113, an inner ring body 011a having a plug hole 0101, the wall of the plug hole 0101 being connected to the innermost annular rib 011c, and the central tube 0113 passing through the plug hole 0101.

[0060] It should be noted that the water softened by the displacement reaction with the resin can flow out of the resin tank 010 through the central pipe 0113, or, during the regeneration operation of the resin, the regenerated liquid can flow into the resin tank 010 through the central pipe 0113 and enter the resin layer.

[0061] The inner ring 011a, serving as the center of the disc 0111, has a insertion hole 0101. A central tube 0113 can pass through this hole, and the size and shape of the insertion hole 0101 match the central tube 0113, allowing for an interference fit. This ensures the central tube 0113 is stably inserted within the insertion hole 0101, preventing loosening or wear between the central tube 0113 and the disc 0111 due to water flow impact and mechanical vibration. The wall of the insertion hole 0101 connects to the innermost annular rib 011c, increasing the structural strength and rigidity of the inner ring 011a, further preventing the central tube 0113 from swaying due to water flow impact.

[0062] Please see Figure 1 and Figure 2 In some embodiments, the depth of the insertion hole 0101 is greater than the thickness of the annular rib 011c.

[0063] Specifically, the depth of the insertion hole 0101 is greater than the thickness of the annular rib 011c. When the central tube 0113 is inserted into the insertion hole 0101, it ensures a deeper insertion length, thus providing better support and positioning for the central tube 0113. Furthermore, the greater hole depth reduces the possibility of stress concentration at the edge of the annular rib 011c due to insertion, preventing damage or deformation of the annular rib 011c and improving the durability and reliability of the entire water distributor assembly 011. The deeper insertion hole 0101 also provides more operating space for installing and removing the central tube 0113.

[0064] Secondly, please refer to Figure 3 and Figure 4 This application embodiment also provides a resin tank 010, which includes an outer cylinder 012, a plug 013, and a water distributor assembly 011 as described above. The water distributor assembly 011 is disposed inside the outer cylinder 012, and the plug 013 is sealed at the opening of the outer cylinder 012.

[0065] Specifically, the bottom of the outer cylinder 012 is provided with a cylinder opening, the size of which is equal to the cross-sectional area of ​​the outer cylinder 012. The water distributor assembly 011 can be installed inside the outer cylinder 012 from the cylinder opening, and the plug 013 can be used to seal the cylinder opening of the outer cylinder 012.

[0066] It should be noted that the resin tank 010 is usually equipped with an upper water distributor and a lower water distributor. The upper water distributor is located at the top of the resin tank 010, and the lower water distributor is located at the bottom of the resin tank 010. The upper water distributor and the lower water distributor are connected by a central tube 0113. The water distributor assembly 011 in this embodiment can be the upper water distributor in the resin tank 010. The beneficial effects of the resin tank 010 in this application are the same as those of the water distributor assembly 011 in this application, and will not be described again here.

[0067] Thirdly, this application provides a water softening system 002, which includes a resin tank 010, a brine tank assembly (not shown in the figure), and a water softening valve 020 as described above. The water softening valve 020 is disposed on the resin tank 010, and the brine tank assembly is connected to the resin tank 010.

[0068] Specifically, the soft water valve 020 is located on the top of the resin tank 010, and the soft water valve 020 can be used to control the water inlet and outlet of the resin tank 010, and can also be used to control the salt particles in the brine tank assembly to be drawn into the resin tank 010. Since the soft water system 002 in this application includes the above-mentioned resin tank 010, the beneficial effects of the soft water system 002 are the same as those of the water distributor assembly 011 in this application, and will not be described again here.

[0069] Fourthly, this application also provides a water purifier (not shown in the figure), which includes a housing assembly (not shown in the figure), a soft water system 002, a water purification system (not shown in the figure), and a hot water system (not shown in the figure). The soft water system 002, the water purification system, and the hot water system are all disposed within the housing assembly. The water purification system is connected to the soft water system 002 through a first pipe, and the hot water system is connected to the water purification system through a second pipe.

[0070] Specifically, the water softening system 002 can be connected to tap water, and the water softening system 002 can soften tap water to form soft water. The soft water can flow into the water purification system, and after being filtered by the water purification system, it becomes pure water. The pure water can flow into the hot water system, and after being heated by the hot water system, it can become hot water for users. Since the water purifier in this application includes the aforementioned water softening system 002, the beneficial effects of the water purifier are the same as those of the water distributor component 011 in this application, and will not be described again here.
