Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a water softening device. Background Technology

[0002] With my country's rapid economic development, people's demand for water is increasing. However, tap water has a high hardness (i.e., high concentration of calcium and magnesium ions), which can lead to scale buildup and a poor washing and bathing experience. Water softeners, as an important water treatment device, can effectively remove calcium and magnesium ions from water through ion exchange technology, thereby reducing water hardness and improving the taste and feel of the water.

[0003] The operation of a typical household water softener mainly consists of a softening process and a regeneration process. During the softening process: the resin exchange tank inside the water softener is filled with cation exchange resin. When hard water containing calcium and magnesium ions passes through the resin exchange tank, sodium ions (or other functional ions) on the resin exchange with the calcium and magnesium ions in the water. Most of the calcium and magnesium ions are adsorbed by the resin, while water with a lower concentration of calcium and magnesium ions flows out, thus softening the water. During the regeneration process: when the calcium and magnesium ions adsorbed on the resin surface reach saturation, its exchange capacity decreases. At this point, countercurrent regeneration technology is needed to flush the resin with brine, replacing the calcium and magnesium ions and restoring the resin's exchange capacity. To control and switch between the softened water path and the regeneration water path within the water softener, a softening valve is usually also included. In related technologies, the soft water circuit and the regeneration water circuit inside the soft water valve are usually set as the same water circuit. However, the flow rate of the soft water circuit is much greater than that of the regeneration water circuit. Therefore, in actual processing, the internal channel of the soft water valve is larger, which leads to uneven distribution of the regenerant during the regeneration process, resulting in poor uniformity of resin regeneration.

[0004] Therefore, there is an urgent need to develop a water softening device to solve the above problems. Utility Model Content

[0050] This embodiment provides a water softening device that softens water flowing through it, reducing water hardness, improving the taste and feel of the water, and enhancing the user's water experience. In this embodiment, the water softening device is specifically a water softener. Of course, in other embodiments, the water softening device can also be a water treatment device that integrates functions such as water purification, water softening, and sterilization.

[0051] like Figures 1-5 As shown, the water softening equipment provided in this embodiment includes a water softening valve 100, a resin tank 200, and a water distributor assembly 300. The water distributor assembly 300 is disposed in the resin tank 200, and softening resin is filled between the two. The resin tank 200 and the water distributor assembly 300 cooperate to form a brine channel 301 and a soft water channel 302. The water softening valve 100 includes a valve body 110 and a first water pipe 120 and a second water pipe 130 spaced apart on the valve body 110. Both the first water pipe 120 and the second water pipe 130 are connected to the resin tank 200. An independent raw water chamber 1 is formed inside the valve body 110. 101. A soft water chamber 1102 and a brine chamber 1103 are provided, and the valve body 110 is also provided with a raw water inlet 1111, a soft water outlet 1112 and a brine suction port 1113. A first water hole 1301 and a second water hole 1302 that are not connected are formed in the second water pipe 130. The raw water inlet 1111, the raw water chamber 1101 and the first water pipe 120 are connected in sequence. The soft water channel 302, the second water hole 1302, the soft water chamber 1102 and the soft water outlet 1112 are connected in sequence. The brine suction port 1113, the brine chamber 1103 and the first water hole 1301 and the brine channel 301 are connected in sequence.

[0052] The water softening equipment provided in this embodiment has the following water softening process: raw water enters the resin tank 200 through the raw water inlet 1111, the raw water chamber 1101 and the first water pipe 120 in sequence. After the water is evenly distributed by the water distributor assembly 300, it is softened by the resin. The softened water then flows out from the soft water outlet 1112 through the soft water channel 302, the second water hole 1302 and the soft water chamber 1102 in sequence for the user to use. The regeneration process is as follows: brine flows to the brine channel 301 through the brine suction port 1113, the brine chamber 1103 and the first water hole 1301 in sequence. After being evenly distributed by the water distributor assembly 300, the softening resin can be regenerated. This configuration allows for the separation of the softened water channel and the regenerated water channel, forming a dual-replenishment scheme for softening and regeneration. This enables the dimensions of each channel to be customized according to actual needs, ensuring that the brine is evenly distributed across the entire cross-sectional layer of the resin tank 200 during the regeneration process. This allows the softened resin to be fully regenerated, improving the utilization rate of the brine.

[0053] like Figures 5-6 As shown, the valve body 110 includes an upper valve body 111 and a lower valve body 112 connected to each other. The upper valve body 111 is provided with staggered first partition ribs 1110, and the lower valve body 112 is provided with staggered second partition ribs 1120. The first partition ribs 1110 and the second partition ribs 1120 cooperate to divide the space between the upper valve body 111 and the lower valve body 112 into the aforementioned raw water chamber 1101, soft water chamber 1102, and brine chamber 1103. By setting the valve body 110 as separate upper valve body 111 and lower valve body 112, the machining of the raw water chamber 1101, soft water chamber 1102, and brine chamber 1103 can be facilitated, reducing machining difficulty and improving machining efficiency.

[0054] Optionally, a sealing element is provided between the corresponding first partition rib 1110 and the second partition rib 1120 to prevent water from flowing between adjacent chambers, thereby ensuring the cleanliness of the water used by the user.

[0055] In this embodiment, the upper valve body 111 and the lower valve body 112 are connected by welding, which has the advantages of stable connection and high connection accuracy. Of course, in other embodiments, the upper valve body 111 and the lower valve body 112 can also be integrally formed, omitting the connection step between the two and improving assembly efficiency. When the upper valve body 111 and the lower valve body 112 are integrally formed, the valve body 110 has a hollow structure, and multiple staggered partition ribs are provided inside the valve body 110. The multiple partition ribs divide the cavity of the valve body 110 into a raw water cavity 1101, a soft water cavity 1102, and a brine cavity 1103. This design can also achieve the above-mentioned effect.

[0056] Optionally, the first water pipe 120 and the second water pipe 130 are directly formed on the lower valve body 112, eliminating the connection between the first water pipe 120, the second water pipe 130 and the lower valve body 112, reducing the connection structure, reducing processing costs, and reducing leakage points on the valve body 110, thereby ensuring the structural sealing of the entire soft water valve 100.

[0057] To discharge the wastewater generated during the regeneration process, a drain port 1114 is also provided on the valve body 110. Specifically, in this embodiment, the soft water valve 100 also includes a switching component, which is adjustablely disposed within the valve body 110 to selectively open the passage between the drain port 1114 and the raw water chamber 1101 or the passage between the raw water inlet 1111 and the raw water chamber 1101. In other words, when the water softening equipment is in normal use, the passage between the drain outlet 1114 and the raw water chamber 1101 is blocked, while the passage between the raw water inlet 1111 and the raw water chamber 1101 is open. At this time, the raw water can enter the resin tank 200 sequentially through the raw water inlet 1111, the raw water chamber 1101, and the first water pipe 120. When the softening resin needs to be regenerated, the passage between the drain outlet 1114 and the raw water chamber 1101 is opened, while the passage between the raw water inlet 1111 and the raw water chamber 1101 is blocked. The wastewater generated after the softening resin regeneration can be discharged from the drain outlet 1114 sequentially through the first water pipe 120 and the raw water chamber 1101.

[0058] It should be noted that this embodiment does not limit the specific structure of the switching component. All switching components that can be applied to soft water equipment for channel switching in the prior art are within the protection scope of this embodiment.

[0059] like Figure 2 , Figure 4 and Figure 7 As shown, the resin tank 200 includes a tank body 210 and an upper end cap 220 covering the top opening of the tank body 210. The upper end cap 220 is provided with a third water pipe 221 and a fourth water pipe 222. The first water pipe 120 is inserted into the third water pipe 221, and the second water pipe 130 is inserted into the fourth water pipe 222. By providing the third water pipe 221 and the fourth water pipe 222 on the upper end cap 220, which can be inserted into the first water pipe 120 and the second water pipe 130 respectively, rapid positioning and assembly between the soft water valve 100 and the resin tank 200 can be achieved, improving the convenience of operation for the operator.

[0060] In this embodiment, a third water hole 2221 and a fourth water hole 2222 surrounding the third water hole 2221 are formed within the fourth water pipe 2222. The first water hole 1301 is connected to the brine channel 301 through the third water hole 2221, and the second water hole 1302 is connected to the soft water channel 302 through the fourth water hole 2222. Specifically, the second water pipe 130 includes a partition pipe 131 and an outer ring pipe 132 surrounding the partition pipe 131. The first water hole 1301 is formed within the partition pipe 131, and the second water hole 1302 is formed between the partition pipe 131 and the outer ring pipe 132. When the third water pipe 221 is inserted into the first water pipe 120, the partition pipe 131 is inserted into the third water hole 2221, so that the first water hole 1301 and the third water hole 2221 are connected, and at the same time, the second water hole 1302 is connected to the fourth water hole 2222. By connecting the isolation pipe 131 to the third water hole 2221, the softened water flow channel and the regenerated water flow channel can be isolated and sealed to prevent cross-contamination between the two channels. By setting the isolation pipe 131, two non-connected water holes can be formed in the second water pipe 130, thereby improving the structural compactness of the soft water valve 100 and reducing its volume to a certain extent, thus meeting the miniaturization design requirements of the soft water equipment.

[0061] like Figure 4 and Figure 5 As shown, the second water pipe 130 is connected to the bottom of the valve body 110 and located between the soft water chamber 1102 and the brine chamber 1103; the top of the isolation pipe 131 is sealed, and a water inlet 1311 communicating with the bottom opening of the isolation pipe 131 is provided on its side wall, and the water inlet 1311 is connected to the brine chamber 1103; a sealing plate 133 is also provided between the isolation pipe 131 and the outer ring pipe 132, one side of the sealing plate 133 is connected to the inner wall of the outer ring pipe 132 near the brine chamber 1103, and the other side of the sealing plate 133 is connected to the outer wall of the outer ring pipe 132 near the brine chamber 1103. That is to say, the water inlet 1311 of the isolation pipe 131 is connected to the bottom opening of the isolation pipe 131 to form the aforementioned first water hole 1301. The bottom opening of the outer ring pipe 132, without the sealing plate 133 covering one side, extends upward into the soft water cavity 1102, forming the aforementioned second water hole 1302.

[0062] Optionally, such as Figure 8 As shown, the outlet of the third water hole 2221 and the inlet of the brine channel 301 are offset along the radial direction of the tank body 210. This design can reduce the flow velocity of the brine from the third water hole 2221 to the brine channel 301, thereby improving the uniformity of resin regeneration.

[0063] Continue as Figure 2As shown, the water distributor assembly 300 includes a central pipe 310 and a lower water distributor 330. The central pipe 310 includes a first central pipe 311 and a second central pipe 312, with the first central pipe 311 sleeved outside the second central pipe 312. The lower water distributor 330 is located at the bottom of the central pipe 310 and includes a softening water distributor 331 and a regenerating water distributor 332. The softening water distributor 331 is located above the regenerating water distributor 332. The first central pipe 311 is connected to the softening water distributor 331, and the second central pipe 312 is connected to the regenerating water distributor 332. A first soft water channel 3021 is formed between the softening water distributor 331 and the regeneration water distributor 332, and a second soft water channel 3022 is formed between the first central pipe 311 and the second central pipe 312. The second soft water channel 3022 is connected to the first soft water channel 3021 to form the aforementioned soft water channel 302. A first brine channel 3011 is formed between the regeneration water distributor 332 and the inner bottom of the resin tank 200, and a second brine channel 3012 is formed inside the second central pipe 312. The first brine channel 3011 and the second brine channel 3012 are connected to form the aforementioned brine channel 301. With the above arrangement, independent brine channels 301 and soft water channels 302 can be formed within the resin tank 200, thereby cooperating with the soft water valve 100 to ensure sufficient regeneration of the softening resin during the regeneration process and improve the utilization rate of brine.

[0064] Optionally, the water distributor assembly 300 also includes an upper water distributor 320, which is located at the top of the central pipe 310, and the first central pipe 311 is connected to the upper water distributor 320. By setting the upper water distributor 320, uniform water distribution can be achieved when the raw water enters the tank 210 during the water softening process, so as to ensure that the softening resin can be fully utilized.

[0065] The following is combined Figures 1-9 Briefly describe the working principle of this water softener:

[0066] 1) Soft water process: The switching component is switched to the first position to open the passage between the raw water inlet 1111 and the raw water chamber 1101, while the passage between the drain outlet 1114 and the raw water chamber 1101 is blocked. The raw water flows sequentially through the raw water inlet 1111, the raw water chamber 1101, the first water pipe 120, and the third water pipe 221 into the tank 210. After being evenly distributed by the upper water distributor 320, it flows into the resin filling area and is softened by the softening resin. The softened water then passes through the softening water distributor 331, and then through the first soft water channel 3021, the second soft water channel 3022, the fourth water hole 2222, the second water hole 1302, and the soft water chamber 1102 before flowing out from the soft water outlet 1112 for user use.

[0067] 2) Regeneration process: The switching component is switched to the second position to block the passage between the raw water inlet 1111 and the raw water chamber 1101, while the passage between the drain outlet 1114 and the raw water chamber 1101 is opened. The brine flows sequentially through the brine inlet 1113, the brine chamber 1103, the first water hole 1301, and the third water hole 2221 into the second brine flow channel 3012 formed in the second central pipe 312. Then, it is evenly distributed by the regeneration water distributor 332 and flows to the softening resin layer. The wastewater generated after the regeneration of the softening resin passes through the upper water distributor 320 and finally through the third water pipe 221, the first water pipe 120, and the raw water chamber 1101 before being discharged from the drain outlet 1114.

[0068] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments do not limit this utility model in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
