[0002] In soft water supply equipment, the water quality requirements are relatively high, and the water hardness must be controlled below 30 mg / L. The locations of soft water usage points in the area are relatively scattered and numerous, with high daily consumption and a large demand for equipment. Soft water supply equipment uses resin to convert hard water into soft water; however, after treating a certain amount of water, the resin needs to be regenerated or replaced, otherwise it cannot effectively convert hard water into soft water. Utility Model Content

[0003] The following is an overview of the subject matter described in detail herein. This overview is not intended to limit the scope of the claims.

[0004] The purpose of this application is to at least partially solve one of the technical problems existing in the related technologies. The embodiments of this application provide an automatic soft water production and supply system that can automatically restore resin and avoid resin failure that would prevent the hard water from being effectively converted into soft water.

[0005] An embodiment of this application discloses an automatic soft water production and supply system, comprising:

[0006] A water softener is connected to a tap water pipe and is used to convert hard water from the tap water pipe into soft water. The water softener is equipped with a soft water preparation module, a resin reduction module, and a soft water flow meter. The soft water preparation module is equipped with resin. Whenever the soft water flow meter detects that the amount of soft water produced has reached a preset threshold, the resin reduction module performs reduction treatment on the resin.

[0007] A soft water tank, which is connected to the water softener, is used to store soft water treated by the water softener;

[0008] A water pump is connected to the soft water tank and is used to pump the soft water tank to the point of use through a water supply pipe.

[0010] According to certain embodiments of this application, the resin is disposed in a resin tank, the resin tank being provided with a port and a port door for opening and closing the port.

[0011] According to certain embodiments of this application, the resin reduction module is provided with a brine tank for storing brine for reducing the resin. The brine tank is connected to the resin tank via a brine pipe, and the brine pipe is equipped with an electronic valve.

[0012] According to certain embodiments of this application, the water softener is equipped with a timer for calculating the time required for the restoration process.

[0013] According to certain embodiments of this application, the soft water tank is provided with a water level electrode and a liquid level relay, and the water level electrode and the liquid level relay constitute a liquid level sensor.

[0014] According to certain embodiments of this application, when the level sensor detects that the water level in the soft water tank is lower than a first preset water level, the water softener operates and supplies water to the soft water tank; when the level sensor detects that the water level in the soft water tank is higher than a second preset water level, the water softener stops supplying water to the soft water tank; wherein, the second preset water level is higher than the first preset water level.

[0018] The above solution has at least the following beneficial effects: Hard water is delivered to the water softener via a tap water pipe. The water softener uses resin in its water softening module to adsorb calcium and magnesium ions from the hard water, converting it into soft water. The soft water is stored in a soft water tank, and a water pump pumps the soft water from the tank to the point of use via a water supply pipe.

[0023] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0024] An embodiment of this application provides an automatic soft water production and supply system.

[0025] Reference Figure 1 The automatic soft water production and supply system includes: a soft water machine 200, a soft water tank 300, and a water pump 400.

[0026] A water softener 200 is connected to a tap water pipe 100. The water softener 200 is used to convert hard water from the tap water pipe 100 into soft water. The water softener 200 is equipped with a soft water preparation module, a resin reduction module, and a soft water flow meter. The soft water preparation module contains resin. Whenever the soft water flow meter detects that the amount of soft water produced has reached a preset threshold, the resin reduction module performs reduction treatment on the resin. A soft water tank 300 is connected to the water softener 200. The soft water tank 300 is used to store the soft water treated by the water softener 200. A water pump 400 is connected to the soft water tank 300. The water pump 400 is used to pump the soft water from the soft water tank 300 to the point of use through the water supply pipe.

[0027] In this embodiment, the tap water pipe 100 delivers hard water to the water softener 200, where the water softener 200 adsorbs calcium (Ca) from the hard water using resin in the water softening module. 2+ ), magnesium (Mg) 2+ Plasma is used to convert hard water into soft water, which is stored in a soft water tank 300. A water pump 400 pumps the soft water tank 300 to the point of use through a water supply pipe. Whenever the soft water flow meter detects that the amount of soft water produced has reached a preset threshold, the resin reduction module performs a resin reduction process to prevent the resin from becoming ineffective and unable to convert hard water into soft water.

[0028] Specifically, the preset threshold is set to 80 m³; that is, whenever the soft water flow meter detects that 80 m³ of soft water has been produced, the resin reduction module performs resin reduction treatment. Of course, in other embodiments, the preset threshold can be set to other values, depending on the actual usage and water quality conditions, but it should be noted that the resin needs to be reduced before it becomes ineffective.

[0029] A soft water flow meter is installed on the soft water output pipe of the soft water preparation module. Soft water treated by the soft water machine 200 is output to the soft water tank 300 through the soft water output pipe; by measuring the amount of soft water flowing through the soft water output pipe by the soft water flow meter, the amount of soft water produced can be calculated.

[0030] In other embodiments, timed regeneration can also be set, for example, the resin can be automatically regenerated every 7 days through the resin reduction module; users can also manually start the reduction program through the control panel.

[0031] For water softener 200, water softener 200 removes calcium from hard water. 2+ Mg 2+ Plasma removal is used to convert hard water into soft water; in this embodiment, Ca in the hard water is adsorbed by resin. 2+ Mg 2+ Plasma is used to convert hard water into soft water. The resin in a water softener 200 is typically a cation exchange resin, whose surface contains exchangeable sodium ions (Na+). + When hard water passes through the resin, Ca 2+ Mg 2+ Plasma will displace the Na on the resin + Ions cause the resin to "fail". During regeneration, a high-concentration sodium chloride solution flows through the resin, and the sodium ions replace the calcium and magnesium ions on the resin, restoring the resin's exchange capacity.

[0032] The resin is placed inside a resin tank, which has an inlet and a valve for opening and closing the inlet. After opening the valve, the resin inside the tank can be easily replaced through the inlet. Hard water enters the resin tank and is converted into soft water by the resin's adsorption properties.

[0033] The resin reduction module is equipped with a brine tank to store the brine used for resin reduction. The brine tank is connected to the resin tank via a brine pipe equipped with an electronic valve. When resin reduction treatment is required, the electronic valve opens, and the brine from the tank flows through the brine pipe to the resin tank to reduce the resin inside. When the resin reduction treatment is complete, the electronic valve closes.

[0034] The water softener 200 is equipped with a timer, which is used to calculate the time required for the restoration process.

[0035] The specific steps of resin regeneration and restoration include backwashing, brine absorption and slow washing, forward washing, and standby and water production recovery.

[0036] During the backwashing stage, the water softener 200 stops producing water and opens the backwash valve, using raw water to flush the resin tank from the bottom upwards, removing impurities, suspended solids, and broken resin particles from the surface of the resin layer. This loosens the resin layer, preparing it for subsequent brine exchange. This process takes approximately 5-15 minutes, and the water flow direction is opposite to the normal water production direction.

[0037] During the brine adsorption and slow rinsing phase, after backwashing, the brine tank valve is opened, and high-concentration brine (approximately 8%-10%) is slowly drawn into the resin tank via siphoning, flowing through the resin bed. When the brine comes into contact with the resin, sodium ions replace calcium and magnesium ions on the resin, forming soluble salts such as calcium chloride and magnesium chloride, which are discharged with the wastewater. Through ion exchange, the resin regains its ability to adsorb sodium ions. This process takes approximately 30 to 60 minutes, with a slow brine flow rate to ensure thorough exchange.

[0038] During the initial rinse phase, after salt absorption is complete, the resin tank is rinsed downwards with raw water from the top to thoroughly remove any remaining salt water and the displaced calcium and magnesium ions. This prevents residual salt in the regenerated soft water from affecting water quality. This process takes approximately 10-20 minutes until the discharged water meets normal soft water standards.

[0039] During the standby and water production recovery phases, after the main wash is completed, the water softener 200 automatically closes the regeneration valve and returns to the water production state, and the resin is fully restored.

[0040] The soft water tank 300 is equipped with a water level electrode 310 and a liquid level relay, which together form a liquid level sensor. When the liquid level sensor detects that the water level in the soft water tank 300 is lower than a first preset water level, the water softener 200 operates and supplies water to the soft water tank 300; when the liquid level sensor detects that the water level in the soft water tank 300 is higher than a second preset water level, the water softener 200 stops supplying water to the soft water tank 300; wherein the second preset water level is higher than the first preset water level. High and low water level alarm signals are installed and configured.

[0041] For example, the second preset water level is set to 3m, and the first preset water level is set to 0.5m. Then, when the level sensor detects that the water level in the soft water tank 300 is lower than 0.5m, the water softener 200 starts working and supplies water to the soft water tank 300; when the level sensor detects that the water level in the soft water tank 300 is higher than 3m, the water softener 200 stops supplying water to the soft water tank 300.

[0042] A solenoid valve 600 is installed at each water point. A water pump 400 is driven by a frequency converter, which is connected to a pressure switch 500 located on the water supply pipe. When all solenoid valves 600 are closed, the pressure switch 500 detects that the pressure in the water supply pipe exceeds a preset pressure threshold, closes, the frequency converter stops working, and the water pump 400 stops working.

[0043] Typically, there are multiple water points, for example, water point 1, water point 2, water point 3, water point 4, water point 5, water point 6, and water point 7.

[0044] The constant pressure water pump 400 is driven by a frequency converter, with a set standard pressure value between 0.15 MPa and 0.18 MPa. The frequency converter starts the water pump 400 via the pressure switch 500 "P" contact. When a water point solenoid valve 600 opens, the pressure in the pipe decreases, triggering the water pump 400 to run. When all water point solenoid valves 600 are closed, the pressure in the pipe increases to an excessive level, stopping the water pump 400.

[0045] The above is a detailed description of the preferred embodiments of this application, but this application is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this application, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
