Description

Technical Field

[0001] This utility model relates to the field of water heater technology, and in particular to a salt tank for detecting salt concentration, a soft water system and a water heater. Background Technology

[0002] In current water treatment technologies, water softening systems use resins to remove hardness components (such as calcium and magnesium ions) from water, thereby softening the water. However, over time, the resin gradually loses its exchange capacity and needs to be regenerated using regenerated brine to restore its function. If the regenerated brine blocks are depleted and not replenished in time, it will not only lead to a decrease in the efficiency of the water softening system, but may even cause irreversible damage to the resin inside the system. Therefore, it is necessary to install a device to monitor the remaining amount of regenerated brine blocks for making regenerated brine. However, in existing technologies, the brine tank and the mixing container for mixing the brine tank and water to make regenerated brine are generally set up separately. Some technologies even have a separate chamber for monitoring the concentration of regenerated brine. This results in a complex and large structure for the entire brine tank equipment with monitoring function, which is not conducive to the miniaturization design of water heaters that use this brine tank equipment. Utility Model Content

[0003] To overcome at least one of the defects described in the prior art, this utility model provides a brine concentration detection salt tank, a soft water system, and a water heater. This solves the problem.

[0004] The technical solution adopted by this utility model to solve its problem is:

[0005] A salt bath for detecting saline concentration includes:

[0006] The box is used to store recycled salt blocks;

[0007] A partition is provided inside the box, and the partition divides the box into a salt storage section and a salt dissolving section. The salt storage section is located at the upper part of the partition for storing regenerated salt blocks, and the salt dissolving section is located at the lower part of the partition for dissolving the regenerated salt blocks. The partition is provided with through holes so that when water enters the salt dissolving section, water can pass through the through holes to contact the regenerated salt blocks located on the other side of the partition for salt dissolution.

[0008] A saline concentration detection device, wherein the saline concentration detection device has a saline concentration detection probe, which is disposed in the salt dissolving section for detecting the concentration of the dissolved saline.

[0009] Furthermore, the saline concentration detection probe is located on one side of the salt dissolving section, or at the bottom of the salt dissolving section.

[0010] Furthermore, the salt dissolving section is provided with a pipe that passes through the side wall of the salt dissolving section for the inflow and outflow of liquid.

[0011] Furthermore, the saline concentration detection probe is located at the inlet of the pipe.

[0012] Furthermore, the inner wall of the box is provided with at least two support members, and the partition is mounted on all of the support members so that a gap is maintained between the partition and the bottom of the box to form the salt dissolving section.

[0013] Furthermore, the top of the support member is provided with an arc structure.

[0014] Furthermore, the support member includes a guide portion and a support portion, the guide portion is connected to the support portion, the guide portion is located on the upper side of the support portion, and the guide portion is inclined from top to bottom toward the middle of the box body.

[0015] Furthermore, the box body is rectangular, and two support members are provided on each of the four side walls adjacent to the bottom wall of the box body.

[0016] This utility model also provides a water softening system, including:

[0017] Water softening device;

[0018] In the aforementioned salt concentration detection salt tank, the salt concentration detection probe is electrically connected to the controller of the water softening device, and the salt dissolving section is connected to the water softening device.

[0019] By adopting the above solution, the controller of the water softener is electrically connected to the brine concentration detection probe. The controller can receive information that the brine concentration is lower than the concentration threshold, and the water softener can then automatically shut down. This prevents damage to the resin inside the water softener caused by continuous operation when the resin needs to be regenerated but cannot be effectively regenerated.

[0020] This utility model also provides a water heater, including:

[0021] Hot water components;

[0022] A water inlet pipe, one end of which is connected to an external water inlet pipe, and the other end of which is connected to the hot water unit;

[0023] A water outlet pipe, one end of which is connected to an external water fitting, and the other end of which is connected to the hot water assembly;

[0024] In the aforementioned water softening system, the water softening device is connected to the inlet pipe or the outlet pipe.

[0025] In summary, the brine concentration detection salt tank, soft water system, and water heater provided by this utility model have the following technical effects:

[0026] 1. By dividing a tank with partitions, the salt storage section at the top of the tank is used for salt storage, and the salt dissolving section at the bottom of the tank is used for making regenerated brine. A brine concentration detection probe is placed in the salt dissolving section to monitor the concentration of the regenerated brine. When the salinity of the mixed brine does not reach the normal standard, it indicates that the remaining regenerated salt blocks are insufficient or have been exhausted. In other words, salt storage, salt dissolving, and residual salt monitoring can be completed in a single tank, which improves the integration of the tank and facilitates the miniaturization design of water heaters or other water softening equipment that use this salt tank.

[0027] 2. The design of the baffle separates the salt dissolving section from the salt storage section, but they are connected by through holes, which ensures that the regenerated salt block can come into contact with the water inside the salt dissolving section. This ensures both the simple structure of the salt storage section and the salt dissolving section and the high efficiency of salt dissolving. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0035] See Figs. 1-2 As shown, this utility model discloses a brine concentration detection salt tank and a soft water system: including a tank body 1, a partition 2, and a brine concentration detection device. The tank body 1 is used to store regenerated salt blocks 4. The partition 2 is located inside the tank body 1, and the partition 2 divides the tank body 1 into a salt storage section 11 and a salt dissolving section 12. The salt storage section 11 is located at the upper part of the partition 2 for storing the regenerated salt blocks 4, and the salt dissolving section 12 is located at the lower part of the partition 2 for dissolving the regenerated salt blocks 4. The partition 2 has a through hole 21 so that when water enters the salt dissolving section 12, water can contact the regenerated salt blocks 4 to dissolve the salt. The brine concentration detection device has a brine concentration detection probe 3, which is located in the salt dissolving section 12 for detecting the concentration of the dissolved brine.

[0036] Specifically, the housing 1 is used to store the regenerated salt blocks 4. A partition 2 is located inside the housing 1, dividing it into a salt storage section 11 located at the top of the partition 2. This section stores the regenerated salt blocks 4, whose size is larger than the through-hole 21 on the partition 2 to prevent them from falling directly into the dissolving section 12. The dissolving section 12 is located at the bottom of the partition 2 and is used to dissolve the regenerated salt blocks 4. The partition 2 has through-holes 21, ensuring that when a predetermined volume of water is injected into the dissolving section 12, the water level is higher than the height of the partition 2, thus ensuring that water can contact and dissolve the regenerated salt blocks 4 through the through-holes 21. A brine concentration detection device includes a brine concentration detection probe 3, which is located inside the dissolving section 12 and used to monitor the concentration of the dissolved brine in real time.

[0037] The working principle of the above structure:

[0038] A predetermined volume of water is injected into the salt dissolving section 12, raising the water level above the height of the partition 2, ensuring that the water can contact the regenerated salt block 4 in the salt storage section 11 through the through-hole 21 on the partition 2. After contact with the regenerated salt block 4, the water begins to dissolve, and the dissolved salt diffuses into the water in the salt dissolving section 12, causing the brine to mix evenly. The brine concentration detection probe 3 monitors the brine in the salt dissolving section 12, and when the preset brine concentration is reached, it flows back into the salt dissolving section 12.

[0039] In some embodiments, the saline concentration detection probe 3 is located on one side of the salt dissolving section 12, or at the bottom of the salt dissolving section 12.

[0040] Specifically, the saline concentration detection probe 3 can be located on one side or at the bottom of the salt dissolving section 12. Specifically, both the side and bottom of the salt dissolving section 12 have walls of the housing 1, facilitating the installation of the saline concentration detection probe 3. These locations are also where the dissolved regenerated salt block 4 finally diffuses, thereby improving detection accuracy.

[0041] In some embodiments, the salt dissolving section 12 is provided with a conduit 13, which passes through the side wall of the salt dissolving section 12 for the inflow and outflow of liquid.

[0042] Specifically, the salt dissolving section 12 is equipped with a pipe 13, which passes through the side wall of the salt dissolving section 12 for the inflow and outflow of liquid. That is, it facilitates the entry of water used for salt dissolution into the salt dissolving section 12 and the outflow of regenerated brine after salt dissolution. More importantly, the pipe 13 is located in the salt dissolving section 12, so that the liquid entering and exiting through the pipe 13 flows out from the bottom of the tank 1, thereby preventing the liquid from interfering with the storage of the regenerated salt block 4.

[0043] In some embodiments, the saline concentration detection probe 3 is located at the inlet of the pipe 13.

[0044] Specifically, the saline concentration detection probe 3 is installed at the inlet of pipe 13. This ensures that the saline concentration detected by the saline concentration detection probe 3 is consistent with the actual saline concentration flowing out of pipe 13.

[0045] Specifically, the brine concentration detection probe 3 is placed at the inlet of pipe 13, allowing it to directly measure the concentration of the brine about to flow out. Because the probe 3 is located at a critical outlet point in the water flow, the detected concentration value is closest to the actual outflowing brine concentration, minimizing errors. Furthermore, if the probe were placed elsewhere, a lag effect in concentration detection might occur due to a longer water flow path or uneven mixing. Placing it at the pipe inlet, however, allows for immediate reflection of the true concentration of the water exiting pipe 13, ensuring real-time data accuracy.

[0046] In some embodiments, the inner wall of the box 1 is provided with at least two support members 14, and the partition 2 is mounted on all the support members 14 so that a gap is maintained between the partition 2 and the bottom of the box 1 to form a salt dissolving section 12.

[0047] Specifically, the support member 14 provides a stable support point for the partition 2. By providing at least two support members 14 on the inner wall of the tank 1, it can be ensured that the partition 2 will not shift or tilt during use, maintaining a horizontal state. More importantly, the design of the support member 14 maintains a certain gap between the partition 2 and the bottom of the tank 1. This gap forms the salt dissolving section 12, allowing water and dissolved brine to flow freely below the partition 2, promoting the full dissolution of the regenerated salt block 4. This further simplifies the overall structure of the salt tank.

[0048] In some embodiments, the top of the support member 14 is provided with an arc structure 141.

[0049] Specifically, when the user places the partition 2 into the housing 1, the arc-shaped structure 141 on the top of the support 14 guides the partition 2 to slide smoothly into the correct position. The smooth curved surface of the arc-shaped structure 141 reduces the friction between the partition 2 and the support 14, making it easier to install the partition 2 in place and avoiding tilting or jamming problems caused by improper installation.

[0050] Furthermore, the arc structure 141 also provides a guiding function when placing the recycled salt block 4. Since the recycled salt block 4 is usually large and heavy, direct placement may generate a large impact force on the partition 2. The arc structure 141 can guide the recycled salt block 4 to be placed more smoothly on the partition 2, reducing the impact and friction on the partition 2 and preventing the partition 2 from deforming or being damaged.

[0051] In some embodiments, the support member 14 includes a guide portion 142 and a support portion 143. The guide portion 142 is connected to the support portion 143. The guide portion 142 is located on the upper side of the support portion 143 and is inclined from top to bottom toward the middle of the housing 1.

[0052] Specifically, when the user places the partition 2 into the housing 1, the guide part 142 is designed so that the partition 2 can slide into the correct position along the inclined surface. Since the guide part 142 is inclined from top to bottom toward the middle of the housing 1, the partition 2 can easily find and fix in its proper position, avoiding tilting or jamming problems caused by improper installation.

[0053] Placement of Regenerated Salt Block 4: When placing the regenerated salt block 4, the guide part 142 also provides a guiding function. The regenerated salt block 4 is usually large and heavy, and direct placement may generate a large impact force on the partition 2. The inclined design of the guide part 142 can guide the regenerated salt block 4 to fall more smoothly on the partition 2, reduce the impact and friction on the partition 2, and prevent the partition 2 from deforming or being damaged.

[0054] In some embodiments, the support member 14 may be composed of an arc structure 141, a guide portion 142 and a support portion 143, which are connected in sequence.

[0055] When the partition 2 and the recycled salt block 4 are placed, the arc structure 141 plays an initial guiding role, and the guiding part 142 provides continuous guidance to accurately place the partition 2 on the support part 143.

[0056] In some embodiments, the housing 1 is rectangular, and two support members 14 are provided on each of the four side walls adjacent to the bottom wall of the housing 1.

[0057] Specifically, in order to balance the two indicators of lightweighting and cost of the box 1 and the partition 2, two support members 14 are installed on each of the four side walls adjacent to the bottom wall of the box 1, thereby providing support for the partition 2 in four directions and reducing the deformation of the partition 2 when storing the recycled salt block 4.

[0058] This utility model also provides a water softening system, including a water softening device and the above-mentioned salt concentration detection salt tank, wherein the salt concentration detection probe 3 is electrically connected to the controller of the water softening device, and the salt dissolving part 12 is connected to the water softening device.

[0059] Specifically, by electrically connecting the controller of the water softener to the brine concentration detection probe 3, the controller can receive information that the brine concentration is lower than the concentration threshold, and the water softener can then automatically shut off to prevent damage to the resin inside the water softener caused by continuous operation when the resin needs to be regenerated but cannot be effectively regenerated.

[0060] This utility model also provides a water heater, including a hot water component, an inlet pipe 13, an outlet pipe 13 and the aforementioned water softening system. One end of the inlet pipe 13 is connected to an external water inlet pipe and the other end is connected to the hot water component. One end of the outlet pipe 13 is connected to an external water fitting and the other end is connected to the hot water component. The water softening device is connected to the inlet pipe 13 or the outlet pipe 13.

[0061] Specifically, the hot water unit is used to heat water. One end of the inlet pipe 13 connects to an external water inlet pipe, and the other end connects to the hot water unit, responsible for introducing external water into the unit. One end of the outlet pipe 13 connects to external water fittings (such as shower heads, faucets, etc.), and the other end connects to the hot water unit, responsible for delivering the heated water to the point of use. The soft water system includes the aforementioned brine concentration detection salt tank and softening device, used to remove hardness components from the water and prevent scale from affecting the hot water unit.

[0062] Optionally, when the water softener is connected to the inlet pipe 13, the water is softened before entering the hot water unit. This effectively prevents scale buildup in the heating element and storage tank, extending the lifespan of the equipment.

[0063] Alternatively, when the water softener is connected to the outlet pipe 13, the water is softened after being heated by the hot water unit. This method is suitable for certain applications, such as when softened hot water needs to be used directly.

[0064] More importantly, the brine concentration detection probe 3 inside the water softener monitors the concentration of the regenerated brine in real time and transmits the data to the controller. When the brine concentration falls below the threshold, the controller automatically shuts down the water softener to prevent the resin from failing due to ineffective regeneration.

[0065] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
