Description

Technical Field

[0001] This utility model relates to the field of water softeners, and in particular to a water distribution device and a water softener including the same. Background Technology

[0002] A water softener is a device that uses ion exchange resin in a softening tank to remove metal ions such as calcium and magnesium from water, which cause high water hardness, thereby softening the water.

[0003] Currently, most water softeners on the market operate in five modes: softening, backwashing, slow brine flushing, forward flushing, and water replenishment. The slow brine flushing mode primarily involves drawing brine into the tank to provide sufficient sodium ions to the resin, replacing the calcium and magnesium ions adsorbed on the resin and restoring its ion exchange capacity. In other words, it uses sodium ions from the resin to exchange for calcium and magnesium ions in the water. Furthermore, it washes away the displaced calcium and magnesium ions and other impurities, ensuring effective softening after resin regeneration. This article focuses primarily on the slow brine flushing mode.

[0004] Under slow brine washing conditions, brine flows in from the inlet center pipe and out from the lower distributor. It then flows from the bottom of the tank upwards, through the resin layer, and finally out through the upper distributor and out of the outlet. However, this resin softening and regeneration process has the following problems.

[0005] Currently, most water softeners on the market have their lower distributor located at the bottom of the tank. Since the amount of resin granules used is typically around 10kg, these granules densely cover the lower distributor. As brine flows from bottom to top through the resin layer, it cannot completely cover all the resin granules; the granule regeneration rate is usually around 60% (industry test data). The remaining 40% of unregenerated resin granules are typically located on the upper outer half of the resin granule layer. This low utilization rate of the upper layer resin granules results in poor overall granule softening and regeneration, leading to a reduction in the amount of softened water produced. This also fundamentally affects the performance parameters of the water softener, resulting in a lower cycle water production. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of existing water distribution devices, where the upper layer of the soft water resin layer is less covered by salt water and the utilization rate is low. This utility model provides a water distribution device and a water softener containing the same.

[0007] The present invention solves the above-mentioned technical problems through the following technical solution:

[0008] A water distribution device is used in a water softener. The water distribution device includes a water softener tank and a water distribution assembly. The water distribution assembly is disposed inside the water softener tank, and a receiving space for accommodating a water softening resin layer is formed between the water softener tank and the water distribution assembly. The water distribution assembly includes an inlet pipe and a first water distributor. The first water distributor is disposed at a first end of the inlet pipe, and a second end of the inlet pipe extends out of the water softener tank and is used for water intake. The first water distributor is located at the bottom of the water softener tank. The inlet pipe, the first water distributor, and the receiving space are sequentially connected to form a passage for brine to enter and pass through the water softening resin layer from the bottom to the top.

[0009] The water distribution assembly also includes a turbulence-generating component, which is positioned to generate an airflow that causes the downstream brine flowing from the bottom to the top of the water softener resin layer to diffuse toward the inner circumferential wall of the water softener tank.

[0010] In this solution, the turbulence-inducing component generates a force that causes the downstream brine to diffuse towards the inner wall of the soft water tank, thereby increasing the area of ​​the upper outer region (i.e., the top outer region) of the soft water resin layer covered by brine and improving the utilization rate of the soft water resin layer.

[0011] Preferably, the turbulence-disrupting component is installed on the outer peripheral wall of the water inlet pipe.

[0012] In this design, the installation position of the aforementioned baffle component allows for a large installation area between the baffle component and the inlet pipe, resulting in a more stable installation. Furthermore, the baffle component is located inside the soft water tank, which helps to reduce the space occupied by the baffle component.

[0013] Preferably, the turbulence component includes an air inlet pipe, which is sleeved outside the water inlet pipe, and there is a cavity between the peripheral wall of the air inlet pipe and the peripheral wall of the water inlet pipe for airflow; the peripheral wall of the air inlet pipe is provided with multiple exhaust holes, which are connected to the cavity so that the airflow in the cavity can be discharged into the soft water resin layer through the exhaust holes.

[0014] In this design, the air inlet pipe is fitted outside the water inlet pipe, resulting in a large installation area and a more stable installation. Furthermore, the cavity is formed inside the water softener tank, without occupying additional space. The air inlet pipe also helps prevent water from flowing directly into the water softener resin layer without passing through the first distributor in case of water pipe damage. Additionally, the vent holes facilitate the airflow from the cavity into the water softener resin layer, generating a force that causes the brine in the resin layer to diffuse towards the inner wall of the water softener tank. This increases the area of ​​the upper outer region of the resin layer covered by brine, improving the utilization rate of the resin layer. Multiple vent holes on the periphery of the air inlet pipe maximize the utilization of the airflow in the cavity and also improve the efficiency of generating the force that causes the brine in the resin layer to diffuse towards the inner wall of the water softener tank.

[0015] Preferably, the exhaust direction of the airflow from the exhaust port is perpendicular to the intake direction of the intake pipe.

[0016] In this design, the airflow direction is limited, preventing cross-interference between airflows. This improves the efficiency of brine diffusion into the inner wall of the soft water tank. Since the brine is closest to the soft water tank in the direction perpendicular to the air inlet pipe, it further enhances the efficiency of brine diffusion into the inner wall of the soft water tank. In addition, by utilizing the kinetic energy of the air, the airflow causes the upper resin particles to flow in a "quicksand" vortex, increasing the surface area for contact and exchange between the resin particles and the brine, and improving the overall utilization rate of the resin particles.

[0017] Preferably, multiple exhaust holes form multiple rows of exhaust holes, and each row of exhaust holes includes multiple exhaust holes evenly spaced along the circumference of the intake pipe.

[0018] In this design, the arrangement of multiple vent holes can further improve the efficiency of generating the force that causes the brine in the water softener resin layer to diffuse towards the inner wall of the water softener tank, and also increase the area of ​​the water softener resin layer covered by the brine. In addition, each row of vent holes includes multiple vent holes evenly spaced along the circumference of the air inlet pipe. This arrangement allows the brine in the water softener resin layer around the water inlet pipe to diffuse towards the inner wall of the water softener tank, further increasing the area of ​​the upper layer of the water softener resin layer covered by brine, and further improving the utilization rate of the water softener resin layer.

[0019] Preferably, the turbulence assembly further includes a shield for blocking or opening the exhaust vents, and the number of exhaust vents blocked or opened by the shield can be adjusted.

[0020] In this solution, the way the shielding components are set can flexibly diffuse the brine in the soft water resin layer that needs to diffuse to the inner wall of the soft water tank. Because the height of the soft water resin layer is different, the location with low brine coverage also varies. The number of vent holes that the shielding components can block or open can be adjusted, which helps to prevent brine that should not diffuse from spreading to the inner wall of the soft water tank.

[0021] Preferably, the shielding component is a sleeve, which is fitted onto the outside of the air intake pipe and can slide up and down relative to the air intake pipe.

[0022] In this design, the sleeve has good shielding performance, and the shape of the sleeve matches the shape of the water inlet pipe, allowing them to fit together perfectly without any gaps, thus ensuring airflow. In other words, the airflow utilization rate is high. Furthermore, because the shape of the sleeve matches the shape of the water inlet pipe, it is convenient for the sleeve to slide up and down relative to the air inlet pipe, making it easy to adjust the number of vent holes to be shielded or opened.

[0023] Preferably, the maximum diameter of the vent hole does not exceed the diameter of the resin particles in the soft water resin layer, so that the resin particles in the soft water resin layer will not pass through the vent hole.

[0024] In this solution, the arrangement of the vent and the resin particles in the soft water resin layer helps to prevent the resin particles from entering the cavity and clogging it, thus affecting the airflow into the soft water tank. Moreover, this also reduces the number of resin particles in the soft water resin layer, thereby reducing the soft water performance of the water distribution device.

[0025] Preferably, the mass of the water softening resin layer is m, the density of the resin particles in the water softening resin layer is ρ, the radius of the water softening tank is r, and the height of the water softening resin layer in the water softening tank is H = m / (ρπr). 2 The vent is located at position h, and along the direction from the top to the bottom of the soft water resin layer, 1 / 3H≤h≤1 / 2H.

[0026] In this solution, the calculation formula for the location of the vent can be used to determine the location of the vent according to different situations, so that the location of the vent corresponds to the area of ​​the soft water resin layer where brine needs to be diffused, so as to quickly process the above-mentioned water distribution device.

[0027] This utility model also provides a water softener, which includes the above-mentioned water distribution device.

[0028] The positive and progressive effects of this utility model are as follows: the turbulence component can generate a force that causes the downstream brine to diffuse towards the peripheral wall of the soft water tank, thereby increasing the area of ​​the upper outer region (i.e. the top outer region) of the soft water resin layer covered by brine and improving the utilization rate of the soft water resin layer.

[0053] The present invention will be further described below with reference to the accompanying drawings and by way of embodiments, but the present invention is not limited to the scope of the embodiments thereon.

[0054] like Figure 1-8As shown, this embodiment provides a water distribution device 100 for use in a water softener. The water distribution device 100 includes a water softener tank 1 and a water distribution assembly 2. The water distribution assembly 2 is disposed inside the water softener tank 1, and a receiving space for accommodating the water softener resin layer 3 is formed between the water softener tank 1 and the water distribution assembly 2. The water distribution assembly 2 includes an inlet pipe 21 and a first water distributor 22. The first water distributor 22 is disposed at the first end of the inlet pipe 21, and the second end of the inlet pipe 21 extends out of the water softener tank 1 and is used for water intake. The first water distributor 22 is located at the bottom of the water softener tank 1. The inlet pipe 21, the first water distributor 22, and the receiving space are sequentially connected to form a passage for brine to enter and pass through the water softener resin layer 3 from the bottom to the top. The water distribution assembly 2 also includes a turbulence emulator, which is disposed at a position that can generate an airflow that causes the downstream brine flowing from the bottom to the top of the water softener resin layer 3 to diffuse toward the peripheral wall of the water softener tank 1.

[0055] In this embodiment, the turbulence-inducing component generates a force that causes the downstream brine to diffuse towards the inner wall of the soft water tank 1, thereby increasing the area of ​​the upper outer region of the soft water resin layer 3 covered by brine and improving the utilization rate of the soft water resin layer 3.

[0056] It should be noted that the water softening resin layer does not fill all the space between the water softening tank 1 and the water distribution component 2. The location of the downstream brine is the upper region of the water softening resin layer 3, and the inner region of the upper region of the water softening resin layer 3 is the area through which the brine mainly flows. When the brine is discharged from the first water distributor 22, the flow rate is slow. In addition, the gaps between the resin particles are small, and the brine diffuses upward slowly due to the combined effects of gravity and resistance. Experiments have shown that slowly adding brine containing colorant from the inlet pipe 21 simulates the slow absorption of real salt. During the washing process, the brine at the bottom of the soft water resin layer 3 slowly diffuses outwards. After a period of time, the resin particles from the bottom to the middle layer of the soft water resin layer 3 are darker in color, indicating that the brine can effectively cover the resin particles in this area. However, the resin particles on the outer upper layer of the soft water resin layer 3 are lighter in color, and even when the upper water surface is stained, the resin particles in this area are still not stained. This proves that the outer upper layer of the soft water resin layer 3 in the water softener is not covered by brine, and the resin particles in this area have poor softening and regeneration effects and low utilization.

[0057] To explain the above experiment more clearly, please refer to... Figure 6 It was found that, without the presence of a flow-turbing component, in the lower layer of the water softening resin layer 3, the brine flow path passes through the inner peripheral wall area of ​​the water softening tank 1. However, in the upper layer of the water softening resin layer 3, the brine flow path gradually moves away from the inner peripheral wall area of ​​the water softening tank 1, resulting in the upper outer area of ​​the water softening resin layer 3 not being covered by brine.

[0058] See again Figure 7It was found that, in the presence of the turbulence-inducing component, in the lower layer of the water softening resin layer 3, the flow path of the brine is still through the inner peripheral wall region of the water softening tank 1. However, in the upper layer of the water softening resin layer 3, the flow path of the brine is subjected to the force generated by the airflow discharged from the vent 232, so that the brine flow path, which is gradually moving away from the inner peripheral wall region of the water softening tank 1, diffuses towards the inner peripheral wall region of the water softening tank 1.

[0059] like Figure 2-3 As shown, the turbulence-disrupting component is installed on the outer peripheral wall of the water inlet pipe 21.

[0060] In this embodiment, the installation position of the aforementioned turbulence-disrupting component allows for a large installation area between the turbulence-disrupting component and the water inlet pipe 21, resulting in a more stable installation. Furthermore, the turbulence-disrupting component is located inside the soft water tank 1, which helps to reduce the space occupied by the turbulence-disrupting component.

[0061] like Figure 6 As shown, the turbulence assembly includes an air inlet pipe 23, which is sleeved on the outside of the water inlet pipe 21. A cavity 24 exists between the peripheral wall of the air inlet pipe 23 and the peripheral wall of the water inlet pipe 21, and the cavity 24 is used for airflow. The peripheral wall of the air inlet pipe 23 is provided with a plurality of exhaust holes 232, which are connected to the cavity 24 so that the airflow in the cavity 24 is discharged into the soft water resin layer 3 through the exhaust holes 232.

[0062] In this embodiment, the arrangement of the air inlet pipe 23 outside the water inlet pipe 21 results in a large installation area and a more stable installation. Furthermore, the cavity 24 is formed inside the water softener tank 1, without occupying additional space. The air inlet pipe 23 outside the water inlet pipe 21 also helps prevent water from flowing directly into the water softener resin layer 3 without passing through the first water distributor 22 should the water inlet pipe 21 be damaged. Additionally, the vent holes 232 facilitate the discharge of airflow from the cavity 24 into the water softener resin layer 3, generating a force that causes the brine in the water softener resin layer 3 to diffuse towards the peripheral wall of the water softener tank 1. This increases the area of ​​the upper outer region of the water softener resin layer 3 covered by brine, improving the utilization rate of the water softener resin layer 3. The multiple vent holes 232 located on the peripheral wall of the air inlet pipe 23 maximize the utilization of the airflow in the cavity 24 and also improve the efficiency of generating the force that causes the brine in the water softener resin layer 3 to diffuse towards the inner peripheral wall of the water softener tank 1.

[0063] It should be noted that the water inlet pipe 21 is located at the center of the water softener 1, and the air inlet pipe 23 is also located at the center of the water softener 1. In this way, the airflow can quickly act on the brine that has not diffused to the inner wall of the water softener 1 through the exhaust pipe, thereby improving the efficiency of the brine diffusion to the inner wall of the water softener 1. This arrangement can also prevent the airflow from being too far from the inner wall of the water softener 1, so that the force generated is insufficient to diffuse the brine to the inner wall of the water softener 1. In addition, the bottom of the air inlet pipe 23 is connected to the first water distributor 22 and forms a seal to prevent airflow leakage.

[0064] like Figure 1-5 As shown, the airflow exiting from the exhaust port 232 is perpendicular to the air intake direction of the intake pipe 23.

[0065] In this embodiment, the aforementioned limitation on the airflow discharge direction prevents cross-interference between airflows, which is beneficial to improving the efficiency of brine diffusion into the inner wall of the soft water tank 1. Since the brine is closest to the soft water tank 1 in the direction perpendicular to the air intake direction of the air intake pipe 23, this setting will further improve the efficiency of brine diffusion into the inner wall of the soft water tank 1. In addition, by utilizing the kinetic energy of the air, the airflow causes the upper resin particles to flow in a "quicksand" vortex, increasing the surface area for contact exchange between the resin particles and the brine, and improving the overall utilization rate of the resin particles.

[0066] It should be noted that the air inlet pipe 23 is parallel to the soft water tank 1, so the airflow discharge direction is also perpendicular to the soft water tank 1.

[0067] like Figure 8 As shown, multiple exhaust holes 232 form multiple rows of exhaust holes 232, and each row of exhaust holes 232 includes multiple exhaust holes 232 evenly spaced along the circumference of the intake pipe 23.

[0068] In this embodiment, the arrangement of multiple rows of vent holes 232 can further improve the efficiency of generating the force that causes the brine in the water softener resin layer 3 to diffuse towards the inner peripheral wall of the water softener tank 1, and can also increase the area of ​​the water softener resin layer covered by the brine. In addition, each row of vent holes 232 includes multiple vent holes 232 evenly spaced along the circumference of the air inlet pipe 23. This arrangement allows the brine in the water softener resin layer 3 around the water inlet pipe 21 to diffuse towards the inner wall of the water softener tank 1, further increasing the area of ​​the upper outer region of the water softener resin layer 3 covered by brine, and further improving the utilization rate of the water softener resin layer 3.

[0069] It should be noted that the number n of exhaust holes 232 around the circumference of the intake pipe 23 is related to its maximum hole diameter R and the diameter d of the intake pipe 23. The maximum number n does not exceed 2πR / d. Referring to the distribution of water distribution ports 221 on the first water distributor 22, n can generally be taken as 36 to 54.

[0070] Furthermore, the maximum number P of vent holes 232 is related to the length L of sleeve 4. The maximum number P of vent holes 232 is ≤ L / d. The number P of vent holes 232 can generally be 6 to 8. Sleeve 4 can completely cover and seal the vent holes 232, preventing them from venting outwards. The vertically movable sleeve 4 can handle situations where the liquid level of the soft water resin layer varies due to different radii of the soft water tank 1. If only three rows of vent holes 232 are located in the upper half of the soft water resin layer 3, the remaining vent holes 232 outside this area can be covered by sleeve 4. With the vertically movable sleeve 4, the water distribution device 100 can be matched with most soft water tanks 1, avoiding the need for different soft water tanks 1 to be paired with different air inlet pipes 23, and reducing mold opening costs.

[0071] like Figure 2-4 As shown, the spoiler assembly also includes a shield for blocking or opening the exhaust port 232, and the number of exhaust ports 232 blocked or opened by the shield can be adjusted.

[0072] In this embodiment, the shielding member can flexibly diffuse the portion of the soft water resin layer that needs to diffuse brine to the inner wall of the soft water tank 1. Because the height of the soft water resin layer is different, the location with low brine coverage also varies. The number of shielding members that block or open the vent holes 232 can be adjusted, which helps to prevent brine that should not diffuse from spreading to the inner wall of the soft water tank 1.

[0073] It should be noted that the size of the shielding component can completely cover all the aforementioned vents 232 at once.

[0074] like Figure 2 As shown, the shielding component is a sleeve 4, which is sleeved on the outside of the air intake pipe 23 and can slide up and down relative to the air intake pipe 23.

[0075] In this embodiment, the sleeve 4 has good shielding performance, and the shape of the sleeve 4 matches the shape of the water inlet pipe 21, so that they can fit together completely without any gaps in the middle, so that airflow can pass through. In other words, the airflow utilization rate is high. In addition, since the shape of the sleeve 4 matches the shape of the water inlet pipe 21, it is convenient for the sleeve 4 to slide up and down relative to the air inlet pipe 23, so as to conveniently adjust the number of vent holes 232 blocked or the number of vent holes 232 opened.

[0076] It should be noted that the sleeve 4 mentioned above can also be other components that can block or open the number of exhaust holes 232, such as structures similar to lifting doors or leaf windows.

[0077] like Figure 1-5As shown, the maximum diameter of the vent hole 232 does not exceed the diameter of the resin particles in the soft water resin layer 3, so that the resin particles in the soft water resin layer 3 will not pass through the vent hole 232.

[0078] In this embodiment, the arrangement of the vent 232 and the resin particles of the soft water resin layer 3 helps to prevent the resin particles from entering the cavity 24 and blocking the cavity 24, thus affecting the airflow into the soft water tank 1. Moreover, this will reduce the amount of resin particles in the soft water resin layer 3, thereby reducing the soft water performance of the water distribution device 100.

[0079] It should be noted that because the airflow blows the brine towards the inner circumferential wall of the water softener tank 1, the brine will not enter the cavity 24 through the vent 232. In addition, the diameter of the vent 232 is in the range of 0.3mm-0.5mm, and the diameter of the resin particles is in the range of 0.6mm-0.7mm. The above settings are because if the diameter of the vent 232 is too small (the diameter of the outlet 51 on the first water distributor 22 is generally 0.3mm), it will reduce the flow rate of the exhaust airflow, and thus fail to affect the flow path of the brine. If the diameter of the vent 232 is too large, the resin particles will enter the cavity 24, affecting the operation of the water softener.

[0080] like Figure 1-5 As shown, the mass of the soft water resin layer 3 is m, the density of the resin particles in the soft water resin layer 3 is ρ, the radius of the soft water tank 1 is r, and the height of the soft water resin layer 3 in the soft water tank 1 is H = m / (ρπr). 2 The vent hole 232 is located at position h, and along the direction from the top to the bottom of the soft water resin layer 3, 1 / 3H≤h≤1 / 2H.

[0081] In this embodiment, the calculation formula for the setting position of the above-mentioned vent 232 can determine the setting position of the vent 232 according to different situations, so that the position of the vent 232 corresponds to the area of ​​the soft water resin layer 3 where the brine needs to be diffused, so as to quickly assemble the above-mentioned water distribution device 100.

[0082] This embodiment also provides a water softener, which includes the above-mentioned water distribution device 100.

[0083] It should be noted that the above-mentioned water distribution device 100 includes a second water distributor 5, which is located at the top of the soft water tank 1 and includes an outlet 51 for discharging the brine that has passed through the soft water resin layer 3.

[0084] In summary, this embodiment has the following advantages:

[0085] 1. The design features a double-layer central pipe (one layer of water inlet pipe 21 and one layer of air inlet pipe 23). The inner water inlet pipe 21 carries brine, while the outer air inlet pipe 23 carries airflow. Brine is also carried within the soft water resin layer 3 outside the air inlet pipe 23. The airflow impact and entrainment improve the flow and diffusion path of the brine within the soft water resin layer 3, increasing the distribution range of the brine in the upper half of the soft water resin layer. This effectively solves the problem of brine not covering the upper outer soft water resin layer, thereby improving the utilization rate of resin particle regeneration in the soft water resin layer during the slow brine washing operation of the water softener.

[0086] 2. An exhaust port 232 is opened in the outer central pipe (air inlet pipe 23) to introduce airflow, which will also cause the upper soft water resin layer 3 to undergo a "quicksand"-like vortex flow under the impact of the airflow. The movement of the resin particles can increase the surface area of ​​the resin particles in contact with the brine for exchange, thereby improving the utilization rate of the resin particles.

[0087] 3. The vertically movable sleeve 4 structure can accommodate different soft water tanks 1, varying levels of the soft water resin layer, and changes in the position of areas where the brine does not cover the resin particles. Using the sleeve 4 structure not only allows for full and effective utilization of the vent 232, improving venting efficiency, but also effectively enhances water distribution efficiency.

[0088] It should also be noted that the water distribution device 100 in this embodiment operates as follows:

[0089] like Figure 4 As shown, the brine enters the soft water resin layer 3 in the soft water tank 1 through the inlet 211 of the inlet pipe 21 and the distribution port 221 of the first water distributor 22, and then passes through the soft water resin layer 3 before being discharged from the outlet 51 of the second water distributor 5.

[0090] like Figure 4 As shown, during the above process, when the sleeve 4 does not block the exhaust port 232, the airflow path is as follows: the airflow enters the cavity 24 between the air inlet pipe 23 and the water inlet pipe 21 through the air inlet 231 of the air inlet pipe 23, and then the airflow enters the upper soft water resin layer through the exhaust port 232 and acts on the brine therein, causing the brine to diffuse towards the inner peripheral wall of the soft water tank 1.
