Description

Technical Field

[0001] This invention belongs to the field of water softening technology, specifically relating to water softening brine tank components and water softeners. Background Technology

[0002] Currently, the most common method for water softening is to use ion exchange resins to adsorb calcium and magnesium ions, thereby reducing water hardness. However, when the ion exchange resin reaches its critical adsorption capacity, calcium and magnesium ions in the water can no longer be adsorbed, and the water softening process cannot be completed. In this case, the ion exchange resin needs to be regenerated.

[0003] The current regeneration process for ion exchange resins involves preparing brine by dissolving sodium chloride, and then rinsing the resin with the brine to complete regeneration. However, in practice, the required concentration of the regeneration brine varies depending on the regeneration time and the degree of adsorption by the ion exchange resin. To avoid insufficient brine concentration for regeneration, existing technologies prepare supersaturated brine each time, resulting in salt waste. Furthermore, existing water softening equipment typically relies on estimation or sensor detection to determine the need for salt addition. This method is inaccurate and cannot guarantee timely salt replenishment. Moreover, existing water softening equipment continues water treatment even when there is a salt shortage, leading to water being discharged before it has been effectively softened. Summary of the Invention

[0004] In view of this, in order to solve the problems mentioned in the background art, the object of the present invention is to provide a soft water brine tank assembly and a soft water machine.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A soft water brine tank assembly includes a brine tank, and a salt guiding mechanism and a water guiding mechanism for replenishing salt and water into the brine tank, respectively.

[0007] The water guiding mechanism includes a water guiding channel communicating with the salt tank, and the water guiding channel is provided with a turbine that can be driven to rotate by the water flowing through the water guiding channel.

[0008] The salt guiding mechanism includes a salt box and a salt guiding channel connecting the salt box and the salt tank, and a spiral feeding rod that cooperates with the turbine drive is rotatably installed in the salt guiding channel.

[0009] Preferably, the soft water brine tank assembly further includes a diverter for supplying water to the water guide channel, and the diverter is provided with a diversion partition and a water supply channel and a diversion channel located on both sides of the diversion partition, respectively, and the water supply channel is connected to the water guide channel.

[0010] Preferably, the diversion partition includes a movable partition and a fixed partition arranged sequentially along the water inlet direction. The movable partition includes a flat plate and an inclined plate fixed sequentially, and a telescopic plate that is slidably connected to the inclined plate is fixed on one side of the fixed partition.

[0011] Preferably, the free end of the inclined plate is also fixedly connected to a positioning plate, and the distributor is also provided with an electric push rod connected to the positioning plate.

[0012] Preferably, one end of the spiral feed rod is coaxially connected to a limiting wheel, one side of the salt box slides through a limiting post, and the outer end of the limiting post is fixed with a limiting plate that can engage with the limiting wheel. A limiting spring is connected between the limiting plate and the outer wall of the salt box. A movable push plate is also connected inside the salt box through a compression spring, and when the limiting post is pushed out by the push plate, the limiting plate engages with the limiting wheel.

[0013] Preferably, the water guiding mechanism further includes a transmission wheel and a gear that are coaxially coupled with the turbine and the screw feed rod, respectively; a guide post is eccentrically connected to the transmission wheel, and a guide frame is slidably coupled to the outside of the guide post; a movable rack is meshed with one side of the gear, and the rack is perpendicularly fixed to the guide frame.

[0014] Preferably, the transmission wheel has a radial groove that slides with the guide post, and a rotatable lead screw is provided in the radial groove, with the lead screw spirally penetrating the guide post.

[0015] Preferably, the spiral feed rod includes a central shaft and a feed sleeve sleeve sleeved outside the central shaft. The gear and the limiting wheel are coaxially fixed at both ends of the central shaft, and a plurality of one-way ratchet teeth are evenly provided between the outer wall of the central shaft and the inner wall of the feed sleeve sleeve, so that the spiral feed rod constitutes an internal friction one-way ratchet mechanism.

[0016] As a general inventive concept, the present invention also provides:

[0017] A water softener includes a water softening tank and a water softening brine tank assembly as described above;

[0018] The soft water treatment tank is equipped with two filter plates, which form a front chamber, a treatment chamber, and a rear chamber that are sequentially matched. The treatment chamber is filled with ion exchange resin, and the diversion channel of the distributor in the soft water salt tank assembly is connected to the front chamber of the soft water treatment tank.

[0019] A drain pipe is connected to one side of the soft water treatment tank, and one end of the drain pipe is connected to two one-way branch pipes. One one-way branch pipe is connected to the front chamber, and the other one-way branch pipe is connected to the rear chamber. A brine pipe is also connected between the front chamber and the brine tank. The rear chamber is also connected to a soft water outlet pipe and a backwash inlet pipe.

[0020] After the water softener is started, it performs the following water treatment steps in sequence:

[0021] Backwash: Water enters the rear chamber through the backwash inlet pipe, and the drain pipe is connected to the front chamber through one of the one-way branch pipes, and water is drained through the drain pipe;

[0022] Regeneration: Water is introduced into the front chamber through the brine pipe, and the drain pipe is connected to the rear chamber through another one-way branch pipe, and water is drained through the drain pipe;

[0023] Forward washing: Water enters through the diverter, part of the water is replenished into the salt tank through the water replenishment channel, and salt is added to the salt tank at the same time. The other part of the water enters the front chamber through the diverter channel. The drain pipe is connected to the rear chamber through another one-way branch pipe and drains water through the drain pipe.

[0024] Softening: Water enters through the distributor, the water supply channel is closed, all water enters the front chamber through the distributor channel, and exits through the soft water outlet pipe.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] (1) A soft water salt tank assembly with a linkage salt guiding mechanism and a water guiding mechanism is set up so as to realize the linkage feeding of salt and water when preparing brine, accurately ensure the brine concentration, meet the regeneration needs, and effectively reduce the waste of salt.

[0027] (2) A diverter is set to control the water inlet in the water guiding mechanism, thereby adjusting the amount of brine prepared per unit time. Furthermore, the diversion of the diverter can be flexibly adapted to the water softening tank of the water softener.

[0028] (3) The reciprocating transmission between the salt guiding mechanism and the water guiding mechanism is realized by using eccentric guide columns, gears, racks and other structures, thereby enabling the spiral feed rod in the salt guiding mechanism to perform intermittent feeding. The eccentricity of the guide column is adjustable, and the linkage feeding ratio of salt and water can be flexibly controlled, thus facilitating the flexible adjustment of the brine concentration.

[0029] (4) The spiral feed rod is based on the central shaft, the feeding sleeve rod and the one-way ratchet to form an internal friction one-way ratchet mechanism, which enables the spiral feed rod to effectively rotate in one direction during the reciprocating transmission process for intermittent feeding.

[0030] (5) A pusher plate is provided to realize the automatic feeding of salt. A corresponding meshing limit structure is also provided to push out the limit post when the salt in the salt box is completely discharged, so that the limit plate meshes with the limit wheel, thereby limiting the linkage of the salt guiding mechanism and the water guiding mechanism to be unable to rotate and drive. That is, when there is a shortage of salt, the water and salt feeding will be automatically stopped, thus reminding the user to replenish salt in time.

[0031] (6) A water softener including a water softening salt tank is set up and the water softener is set to start up according to the steps of backwashing-regeneration-forward washing-softening. The preparation of brine is completed in the forward washing step. However, once there is a shortage of salt, the preparation of brine and the corresponding forward washing step cannot be performed, which makes the softening step impossible to perform. That is, the entire water softener cannot output water when there is a shortage of salt, thus avoiding the problem of discharging unsoftened water. Attached Figure Description

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0050] This embodiment provides a soft water brine tank assembly, such as... Figure 1 As shown, the soft water brine tank assembly includes a brine tank 100, a brine guiding mechanism 200, a water guiding mechanism 300, and a diverter 400.

[0051] like Figure 10 As shown, the diverter 400 internally includes a diverting baffle 410 and a water supply channel and a diverting channel located on both sides of the diverting baffle 410. Specifically, based on the adjustment of the diverting baffle 410, the flow rate of the water supply channel and the diverting channel is variable, and the water supply channel is used to supply water to the water guiding mechanism 300. In addition, the diverter 400 is externally connected to an inlet pipe that supplies water to the water supply channel and the diverting channel.

[0052] like Figure 2 As shown, the water guiding mechanism 300 includes a water guiding channel that connects the water supply channel and the salt tank 100, and a turbine 301 that can be driven to rotate by the water flow passing through the water guiding channel is provided in the water guiding channel.

[0053] like Figure 1 and Figure 2As shown, the salt guiding mechanism 200 includes a salt box 201 and a salt guiding channel connecting the salt box 201 and the salt tank 100, and a spiral feeding rod 202 that is driven and cooperates with the turbine 301 is rotatably installed in the salt guiding channel.

[0054] Based on the above, the principle of brine preparation achieved by the integrated soft water brine tank assembly is as follows:

[0055] Water enters through the inlet pipe connected to the outside of the diverter 400. The water flow is divided into two parts by the diversion partition 410, with one part flowing into the water supply channel and the other part flowing into the diversion channel.

[0056] The water supply channel is connected to the water guide channel. Water flows into the water guide channel and drives the turbine 301 to rotate. Specifically, to ensure that the turbine 301 can rotate effectively, the water supply channel can be used to achieve a pressurized jet of water flow, thereby increasing the power of the water flow to drive the turbine 301.

[0057] The water guide channel is also connected to the brine tank 100, so water can still enter the brine tank 100 while the turbine 301 is rotating;

[0058] The rotational transmission of the turbine 301 drives the screw feed rod 202 to rotate;

[0059] Solid salt is stored in salt box 201, such as Figure 1 As shown, a feed inlet is provided on one side of the top of the salt box 201, and the feed inlet is directly below the feed inlet of the salt guiding channel. In addition, a discharge outlet connected to the salt tank 100 is provided at the bottom of the salt guiding channel. Specifically, the rotation of the spiral feed rod 202 allows the salt in the salt box 201 to enter the salt guiding channel from the feed inlet and then be discharged into the salt tank 100 from the discharge outlet.

[0060] Water and salt are mixed and dissolved in salt tank 100 to form brine. The concentration of brine is determined by the transmission ratio between turbine 301 and screw feed rod 202, and the amount of brine prepared is determined by the flow rate of water replenishment channel (i.e., the water inlet of salt tank 100).

[0061] In this embodiment, based on such Figure 11 and Figure 12As shown, the diversion partition 410 includes a movable partition 411 and a fixed partition 412 arranged sequentially along the water inlet direction. The movable partition 411 includes a flat plate a and an inclined plate b fixed sequentially, and a telescopic plate 413 slidably connected to the inclined plate b is fixed to one side of the fixed partition 412. The telescopic plate 413 is composed of multiple slidingly fitted unit plates, and the telescopic length of the telescopic plate 413 varies depending on the positioning position of the movable partition 411. Specifically, the telescopic plate 413 is used to connect the flat plate a to the fixed partition 412 and ensure that the water supply channel and the diversion channel do not interfere with each other. In addition, a positioning plate 414 is fixedly connected to the free end of the inclined plate b, and an electric actuator connected to the positioning plate 414 is also provided in the diverter 400. Therefore, the positioning plate 414 and the entire movable partition 411 can be moved under the drive of the electric actuator. Figure 10 In the structure shown, the positioning plate 414 is parallel to the fixed partition 412, and the plate a is close to the side where the water inlet pipe is located.

[0062] In this embodiment, based on such Figure 4 and Figure 5 The structure shown enables transmission between the turbine 301 and the screw feed rod 202. Specifically, the water guiding mechanism 300 further includes a transmission wheel 302 and a gear 303 coaxially engaged with the turbine 301 and the screw feed rod 202, respectively. A guide post 304 is eccentrically connected to the transmission wheel 302, and a guide frame 305 is slidably engaged with the outer side of the guide post 304. A movable rack 306 is meshed with one side of the gear 303, and the rack 306 is perpendicularly fixed to the guide frame 305. Therefore, when the turbine 301 rotates under the drive of water flow, the transmission wheel 302 rotates accordingly, thereby causing the guide post 304 to rotate eccentrically. The sliding engagement between the guide post 304 and the guide frame 305 drives the guide frame 305 and the rack 306 to reciprocate, which in turn drives the gear 303 to rotate reciprocally.

[0063] Further integration Figure 8 and Figure 9 It is understood that the spiral feed rod 202 includes a central shaft 2021 coaxially fixed with the gear 303 and a feed sleeve 2022 sleeved outside the central shaft 2021. Multiple one-way ratchet teeth 2023 are evenly arranged between the outer wall of the central shaft 2021 and the inner wall of the feed sleeve 2022, so that the spiral feed rod 202 constitutes an internal friction one-way ratchet mechanism. Based on this, when the gear 303 reciprocates, the central shaft 2021 rotates accordingly. With the cooperation of the one-way ratchet teeth 2023, the central shaft 2021 can only drive the feed sleeve 2022 to rotate in one direction. Therefore, combined with... Figure 6As illustrated, when the turbine 301, transmission wheel 302, and guide post 304 cooperate to achieve one eccentric rotation, the total reciprocating distance of the rack 306 is 2L1, meaning the driving distance for the feeding sleeve 2022 to rotate unidirectionally with the central shaft 2021 is L1. Assuming that under the drive of the driving distance L1, the gear 303, central shaft 2021, and feeding sleeve 2022 rotate synchronously n times, the corresponding feeding amount of the spiral feeding rod 202 is W, meaning the amount of salt fed per revolution of the turbine 301 is W. This allows for precise determination of the salt and water feeding amounts, thereby accurately ensuring the brine concentration.

[0064] Furthermore, the transmission wheel 302 has a radial groove that slides with the guide post 304. A rotatable lead screw 307 is installed within the radial groove, and the lead screw 307 spirally passes through the guide post 304. Thus, the eccentricity of the guide post 304 can be adjusted by rotating the lead screw 307. See [reference needed] for details. Figure 6 As shown in the diagram, when the degree of eccentricity of the guide post 304 is different, the driving distance formed by the turbine 301 for each rotation is different. In the right figure, L2 < L1 in the left figure. At this time, the feeding amount of the screw feeder 202 is reduced accordingly under the drive of the driving distance L2, while the water intake remains unchanged (turbine 301 rotates once). Thus, the actual brine concentration can be flexibly adjusted.

[0065] In this embodiment, regarding the connection between the salt box 201 and the corresponding feed inlet, combined with... Figure 1 and Figure 7 As shown, a movable pusher plate 2013 is connected to the salt box 201 via a compression spring. Specifically, when the salt box 201 is full of salt, the compression spring is compressed, and the pusher plate 2013 moves away from the feed inlet of the salt box 201. As the spiral feed rod 202 rotates and feeds salt, the amount of salt stored in the salt box 201 gradually decreases. At this time, the pusher plate 2013 is driven to move closer to the feed inlet of the salt box 201 under the rebound of the compression spring, and pushes the salt in the salt box 201 towards the feed port. Preferably, to ensure that the salt box 201 can be replenished smoothly, the inner cavity of the salt box 201 is preferably set to be inclined, and the side where the feed port and feed inlet are located is higher than the opposite side.

[0066] In conjunction with the aforementioned pusher plate 2013, such as Figure 3 and Figure 7As shown, one end of the spiral feed rod 202 is coaxially connected to a limiting wheel 203 (the gear 303 and the limiting wheel 203 are coaxially fixed at both ends of the central shaft 2021). A limiting post 2011 slides through one side of the salt box 201, and a limiting plate 2012 that meshes with the limiting wheel 203 is fixed to the outer end of the limiting post 2011. A limiting spring is connected between the limiting plate 2012 and the outer wall of the salt box 201, and the spring force of the compression spring is greater than that of the limiting spring. Based on this, when the pusher plate 2013 is pushed by the compression spring to... Figure 7 When the indicated position is reached, it means that the salt in the salt box 201 has been completely discharged, and the limiting post 2011 is pushed out by the limiting plate 2013. At this time, the limiting plate 2012 moves outward and engages with the limiting wheel 203, thereby limiting the movement of the limiting wheel 203, the central shaft 2021, the gear 303, the rack 306, the guide post 304, the transmission wheel 302, the turbine 301, and other structures. That is, when the salt box 201 is low on salt, the entire soft water salt tank assembly cannot send water into the salt tank 100 (water can enter the distributor 400, but cannot enter the water guiding mechanism 300), thus forming an abnormal operation and achieving the effect of reminding that salt is low, thereby ensuring timely replenishment of salt.

[0067] Another embodiment

[0068] This embodiment provides a water softener, such as... Figure 13 As shown, the water softener includes a water softening tank 10 and a water softening salt tank assembly as described in the above embodiments.

[0069] Further reference Figure 14 As shown, the soft water treatment tank 10 is provided with two filter plates 11, and the two filter plates 11 form a front chamber, a treatment chamber and a rear chamber that are arranged in sequence within the soft water treatment tank 10. The treatment chamber is filled with ion exchange resin, and the diversion channel of the diverter 400 in the soft water salt tank assembly is connected to the front chamber of the soft water treatment tank 10.

[0070] In addition, a drain pipe 12 is connected to one side of the soft water treatment tank 10, and one end of the drain pipe 12 is connected to two one-way branch pipes 13. One one-way branch pipe 13 is connected to the front cavity, and the other one-way branch pipe 13 is connected to the rear cavity. A brine pipe 14 is also connected between the front cavity and the brine tank 100. The rear cavity is also connected to a soft water outlet pipe 15 and a backwash inlet pipe 16.

[0071] Based on the specific structure of the water softener disclosed above, this embodiment also specifically sets the startup procedure of the water softener. Preferably, after the water softener is started, the following water treatment steps are executed in sequence:

[0072] Backwash: Water enters the rear chamber through the backwash inlet pipe 16, and the drain pipe 12 is connected to the front chamber through one of the one-way branch pipes 13, and drains water through the drain pipe 12 (backwashing ion exchange resin).

[0073] Regeneration: Water is introduced into the front chamber through the brine pipe 14, and the drain pipe 12 is connected to the rear chamber through another one-way branch pipe 13, and water is drained through the drain pipe 12 (the brine rinses the ion exchange resin).

[0074] Forward washing: Water enters through the diverter 400, part of the water is replenished into the brine tank 100 through the water replenishment channel, and salt is added to the brine tank 100 at the same time. The other part of the water enters the front chamber through the diverter channel. The drain pipe 12 is connected to the rear chamber through another one-way branch pipe 13, and water is drained through the drain pipe 12 (to wash away the residual brine in the ion exchange resin and replenish the brine in the brine tank 100 for the next regeneration).

[0075] Softening: Water enters through the distributor 400, the water supply channel is closed (by the movable baffle 411 blocking the water supply channel), all water enters the front chamber through the distributor channel, and exits through the soft water outlet pipe 15 (water softening treatment, removal of calcium, magnesium and other ions from the water).

[0076] Regarding the aforementioned start-up steps, the forward washing step includes the preparation of brine in the soft water brine tank assembly, specifically when the pusher plate 2013... Figure 7 When the material is pressed against the feed side of the salt box 201, the feed inlet of the salt box 201 is blocked. Due to the compression of the compression spring, the pusher plate 2013 pushes out the limiting post 2011, causing the limiting plate 2012 to engage with the limiting wheel 203. This prevents the limiting wheel 203 and the central shaft 2021 from rotating, thus preventing the integral spiral feed rod 202 and the turbine 301 from rotating. Consequently, water cannot enter the water supply channel and the water guiding mechanism 300, causing an abnormality in the forward washing step (further configured so that the water softener stops and alarms when any step malfunctions). Since the forward washing step cannot proceed smoothly, the subsequent softening step cannot be performed, thus ensuring that the water softener in this embodiment does not discharge unsoftened water.

[0077] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
