Description

Technical Field

[0001] This application relates to the field of water softener equipment technology, and in particular to a water softening system, a water softening system control method, a device, and water softener equipment. Background Technology

[0002] Water contains hardness ions such as calcium and magnesium. These hardness ions negatively impact daily use, including reduced washing performance, decreased thermal efficiency due to scaling on pipe walls, and skin irritation. Water softeners use ion exchange resins to replace these hardness ions, effectively removing them and softening the water. However, the replacement capacity of ion exchange resins is limited; once the resin becomes ineffective, it needs to be regenerated using high-concentration saline solution.

[0003] Existing water softening systems have low utilization rates of ion exchange resins during operation. To achieve the required water treatment volume, the amount of ion exchange resin needs to be increased, resulting in an excessively large overall size of the water softener. Furthermore, when using high-concentration brine for regeneration, the salt concentration and flow rate during the regeneration process are significantly affected by water pressure fluctuations, leading to unstable regeneration performance.

[0059] It is understandable that "at least one" refers to one or more, and "multiple" refers to two or more. "At least a part of an element" refers to part or all of an element.

[0060] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0061] In one embodiment, such as Figure 1 As shown, a soft water system is provided, including: a resin container 102, a brine generating device 103, a water circuit switch, a power assembly, and a controller. The resin container includes a resin channel for filling ion exchange resin. The total lateral length of the resin channel is greater than the total longitudinal length of the resin channel, and the water flow direction in the resin container is parallel to the flow direction of the resin channel.

[0062] The brine generation device includes a salt dissolving channel for instantaneous generation of regenerated brine, wherein the water flow direction within the brine generation device is parallel to the flow direction of the salt dissolving channel.

[0063] The water circuit switch is located at the water circuit connection of the soft water system. The resin container is connected to the brine generating device through the water circuit switch. The power unit is located at both ends of the brine generating device. Both the power unit and the water circuit switch are connected to the controller.

[0064] The controller is used to control the switching state of the corresponding water circuit switches and the start / stop state of the corresponding power components according to the system control commands, so that the water flows in the direction corresponding to the working mode to be achieved.

[0065] In a specific embodiment, the resin channel in the resin container 102 is used to load ion exchange resin, including an inlet, an outlet, and intercepting nets disposed at the inlet and outlet of the resin container 102. It should be noted that the resin container 102 in this embodiment is placed horizontally; therefore, the total lateral length of the resin channel is greater than the total longitudinal length of the resin channel. The lateral length is the total length of the channel in the lateral direction, and the longitudinal length is the total length of the channel in the longitudinal direction. In this embodiment, the lateral direction can be a direction parallel to the ground, and the longitudinal direction can be a direction perpendicular to the ground.

[0066] The water flow direction inside the resin container is parallel to the flow direction of the resin channel; that is, inside the tank, the water flow direction is parallel to the ground and flows horizontally. Compared with the conventional placement of water softeners where the water flow direction is perpendicular to the ground, the resin container 102 in this embodiment is flatter and does not occupy height space, thereby effectively reducing the size of the water softener equipment.

[0067] In addition, the resin container 102 in this embodiment may include only one resin flow channel, making the tank flow a single linear flow channel. The resin container 102 in this embodiment may also include multiple layers of resin flow channels, with partitions separating the channels. Alternatively, the flow channels of the resin container 102 can be separated directly by bending and splicing the tank body. In a preferred embodiment, the resin container 102 with a multi-layered resin flow channel structure effectively increases the effective contact distance between water and resin, thereby improving the softening performance of the water softening system.

[0068] Since the resin channel of the resin container 102 in this embodiment is arranged horizontally, a suitable ratio of channel length to channel diameter needs to be set so that the water can flow in the resin channel at a stable velocity under the action of water pressure. In this embodiment, the minimum ratio of the effective channel length to the effective diameter of the resin channel is 3:1, and the maximum ratio is 85:1. This embodiment does not limit the specific values ​​of the effective channel length and effective diameter of the resin channel, and can be adaptively configured according to the needs of the actual application scenario. It should be noted that the effective channel length of the resin channel refers to the total length of the channel loaded with ion exchange resin. The effective diameter of the resin channel is the longest distance between the two ends of the cross-section of the resin channel.

[0069] In this embodiment, the brine generating device 103 is used to load solid salt, and the filtered water in the mixing tank 104 can form a high-concentration brine solution. This embodiment can control the salt concentration of the dissolved salt by adjusting the water flow rate entering the brine generating device 103 and adjusting the length of the salt-dissolving channel inside the brine generating device 103. The length of the salt-dissolving channel in the brine generating device 103 in this embodiment can be a single-layer channel or a multi-layer channel; this embodiment does not limit the specific structure of the brine generating device 103. In a preferred embodiment, by setting different numbers of baffles inside the brine generating device 103, the length of the salt-dissolving channel can be effectively extended within a limited space, increasing the contact time between water and salt, thereby increasing the brine concentration of the generated brine. In this embodiment, the water tank 104 is used to store the filtered water after the pre-filter and is used in the corresponding operating mode.

[0070] In a specific embodiment, the power components are located at both ends of the brine generating device. The brine generating device 103 in this embodiment adopts an instantaneous brine generating method. The power components can be controlled by the controller to provide driving force to control the flow rate and flow rate of the water in the brine generating device 103, thereby stably achieving high-precision brine concentration control. This can effectively improve the utilization rate of brine and enhance the regeneration efficiency for resin regeneration.

[0071] In this embodiment, the water circuit switch is used to realize water circuit switching control corresponding to various working modes, so that the water flows in a specified direction, thereby completing processes such as water softening output treatment, backwashing treatment of resin container 102, and regeneration treatment of resin container 102.

[0072] Specifically, the controller in this embodiment can be a microcontroller, microprocessor unit, or central processing unit, etc. This embodiment does not limit the specific type of controller and can adaptively configure it according to the needs of the actual application scenario. The system control commands are operation instructions generated by the water softener equipment corresponding to the desired operating mode. System control commands can be automatically generated following system operation or generated based on user operations. For example, if the system control commands are used to implement the soft water production mode, then the system control commands need to be automatically generated based on user operation instructions. If the system control commands are used to implement the salt resin regeneration mode, then the system control commands can be automatically generated based on the corresponding system time intervals.

[0073] In summary, this embodiment provides a water softening system. By arranging the resin container and brine generator in a horizontal configuration, the space occupied by various components in the water softening system can be effectively reduced, resulting in a flatter body for the water softener and a smaller overall size, making it easier to install in other electrical appliances. Secondly, the water softening system in this embodiment achieves water softening, resin container backwashing, and regeneration using a small number of switches and pumps, proposing a novel water circuit design that effectively improves the utilization rate of ion conversion resin and solid salt, reducing solid salt waste. Furthermore, the water softening system proposed in this embodiment is unaffected by inlet water pressure, ensuring that the overall performance remains at its optimal value, effectively improving the stability of the regenerated brine concentration control and the water softening effect.

[0074] In a specific embodiment, such as Figure 1 As shown, a soft water system is provided, including: a pre-filter 101, a resin container 102, a brine generator 103, a water tank 104, a controller, a first switch 105, a second switch 106, a third switch 107, a fourth switch 108, a fifth switch 109, a sixth switch 110, a seventh switch 111, a first water pump 112, and a second water pump 113.

[0075] Specifically, the inlet of the pre-filter 101 is connected to the inlet of the softening water system, and the outlet of the pre-filter 101 is connected to the inlet of the resin container 102 via a first switch 105. The outlet of the resin container 102 is connected to the outlet of the softening water system via a second switch 106. The inlet of the softening water system is used to connect to the raw water body. In practical applications, the raw water body is usually tap water; this embodiment does not limit the type of raw water body. The outlet of the softening water system is used to output the target water body, which is softened water after filtration and softening treatment.

[0076] The outlet of the pre-filter 101 is connected to the outlet of the resin container 102 via a third switch 107, and the inlet of the resin container 102 is connected to the wastewater outlet of the soft water system via a fourth switch 108. The wastewater outlet of the soft water system is used to discharge wastewater generated during the cleaning and regeneration of the resin container 102. In this embodiment, the soft water system discharges wastewater through the inlet of the resin container 102 during both the cleaning and regeneration processes.

[0077] The outlet of the pre-filter 101 is connected to the inlet of the water tank 104 via the fifth switch 109. The first outlet of the water tank 104 is connected to the inlet of the brine generator 103 via the first water pump 112. The outlet of the brine generator 103 is connected to the outlet of the resin container 102 via the sixth switch 110, the second water pump 113, and the seventh switch 111. The second outlet of the water tank 104 is connected to the outlet of the resin container 102 via the sixth switch 110, the second water pump 113, and the seventh switch 111. In this embodiment, the water tank 104 includes a first outlet and a second outlet. Under different regeneration and cleaning conditions, the water in the water tank 104 flows out through the corresponding outlet.

[0078] The controller is connected to the first switch 105, the second switch 106, the third switch 107, the fourth switch 108, the fifth switch 109, the sixth switch 110, the seventh switch 111, the first water pump 112, and the second water pump 113 respectively. The controller is used to control the on / off state of the corresponding switch and the start / stop state of the corresponding water pump according to the system control command, so that the water flows in the direction corresponding to the working mode to be achieved.

[0079] Specifically, in this embodiment, the pre-filter is used to filter large particles in the raw water, such as silt and hair, to initially intercept the water entering the softening system and ensure the softening efficiency of the system.

[0080] In a specific embodiment, the first switch 105, the second switch 106, the third switch 107, the fourth switch 108, and the fifth switch 109 are all solenoid valve switches, the sixth switch 110 is a one-position two-way solenoid valve, and the seventh switch 111 is a stop valve.

[0081] It should be noted that this embodiment does not limit the specific form of the switching valve, and it can be configured according to the needs of the actual application scenario. For example, the first switching element 105 and the third switching element 107 can be the same one-position two-way solenoid valve, the first switching element 105 and the fifth switching element 109 can be the same one-position two-way solenoid valve, and the third switching element 107 and the fifth switching element 109 can also be the same one-position two-way solenoid valve. In a feasible embodiment, the first switching element 105, the third switching element 107, and the fifth switching element 109 can also be the same one-position three-way solenoid valve. The three outlets of the one-position three-way solenoid valve are respectively connected to the inlet and outlet of the resin container 102 and the inlet of the water tank 104.

[0082] In one embodiment, such as Figure 1 As shown, the resin container 102 includes at least one resin flow channel, which is arranged laterally within the resin container.

[0083] In a specific embodiment, the resin container 102 is placed horizontally. The resin container 102 can have a structure including only one resin channel or a structure including multiple resin channels. It should be noted that the length of a single resin channel in a resin container 102 with a multi-layer resin channel structure is less than the length of a single resin channel in a resin container 102 with a single-layer resin channel structure.

[0084] In this embodiment, the flow channels of the resin container 102 can be divided by setting a partition plate, thereby achieving a longer resin flow channel within a fixed tank size. This can further improve the exchange rate between the resin and hardness ions in the water, effectively enhancing the softening ability of the needle water softening system.

[0085] In a specific embodiment, the operating modes to be implemented include at least a first operating mode, a second operating mode, a third operating mode, and a fourth operating mode. The first operating mode corresponds to the water production mode of the soft water system, the second operating mode corresponds to the backwashing mode of the soft water system, the third operating mode corresponds to the salt dissolution regeneration mode of the soft water system, and the fourth operating mode corresponds to the slow wash mode of the soft water system. It should be noted that the naming of each operating mode in this embodiment does not limit the function of the corresponding operating mode, but is only used to describe the functions that can be implemented under the corresponding operating mode. The following provides a detailed description of each operating mode.

[0086] In one embodiment, if the system control command is used to implement the first working mode, the controller controls the corresponding water circuit switch to be in the open state so that the water flows into the resin container in the forward direction and is softened by the ion exchange resin to obtain the target water.

[0087] like Figure 2As shown, if the system control command is used to implement the first working mode, the controller controls the first switch 105 and the second switch 106 to be in the open state, controls other switches to be in the closed state, and controls all water pumps to be in the stopped state, so that the water flows from the inlet of the soft water system through the pre-filter 101, the first switch 105, the inlet of the resin container 102, the outlet of the resin container 102, and the second switch 106 to the outlet of the soft water system.

[0088] Specifically, the first working mode in this embodiment is the target water body production mode, which is used to generate the target water body and output the target water body through the outlet of the soft water system.

[0089] In a specific embodiment, the principle of implementing the first working mode in this embodiment is as follows: the raw water body first passes through the pre-filter 101 for preliminary purification to obtain filtered water body. At this time, the controller controls the first switch 105 and the second switch 106 to open, and the other switches to close, so that the filtered water body after preliminary purification flows into the resin container 102 from the inlet along direction 1, flows horizontally along the resin flow channel in the tank, and the ion exchange resin fully softens the water body. The softened water body is discharged from the outlet of the resin container 102 along direction 2, and flows out to the outlet of the soft water system through the second switch 106.

[0090] In one embodiment, if the system control command is used to implement the second working mode, the controller controls the corresponding water circuit switch to be in the open state so that water flows back into the resin container to backwash the resin container.

[0091] like Figure 3 As shown, if the system control command is used to implement the second working mode, the controller controls the third switch 107 and the fourth switch 108 to open, controls other switches to close, and controls all water pumps to stop, so that the water flows from the inlet of the soft water system through the pre-filter 101, the third switch 107, the outlet of the resin container 102, the inlet of the resin container 102, and the fourth switch 108 to the wastewater outlet of the soft water system.

[0092] Specifically, the second working mode is the backwashing mode of resin container 102. The filtered water after the pre-filter 101 is used to backwash the resin container 102. A certain flow rate of filtered water is introduced in the opposite direction to the water production process. This loosens the ion exchange resin in the resin container 102 and cleans the resin container 102 by carrying out the pollutants intercepted by the resin particles through the water flow.

[0093] In a specific embodiment, the principle of implementing the second working mode in this embodiment is as follows: the controller controls the third switch 107 and the fourth switch 108 to open, so that the filtered water purified by the pre-filter 101 flows from the outlet of the resin container 102 into the resin container 102 along direction 3, and then flows out of the resin container 102 from the inlet of the resin container 102 along direction 4, and flows out to the sewage outlet of the soft water system through the fourth switch 108, and the wastewater is discharged through the sewage outlet of the soft water system.

[0094] In one embodiment, if the system control command is used to implement the third working mode, the controller controls the corresponding water circuit switch to the open state and controls the corresponding power component to the start state, so that the water flows into the brine generating device at a preset flow rate, and then controls the regenerated brine generated in the brine generating state to flow back into the resin container at a preset flow rate to regenerate the ion exchange resin in the resin container.

[0095] like Figure 4 As shown, if the system control command is used to implement the third working mode, the controller controls the fourth switch 108, the fifth switch 109, the sixth switch 110, and the seventh switch 111 to be in the open state, controls the other switches to be in the closed state, and controls the first water pump 112 and the second water pump 113 to be in the start state, so that the water flows from the inlet of the soft water system through the pre-filter 101, the fifth switch 109, the inlet of the water tank 104, the first outlet of the water tank 104, the first water pump 112, the inlet of the brine generating device 103, the outlet of the brine generating device 103, the sixth switch 110, the second water pump 113, the seventh switch 111, the outlet of the resin container 102, the inlet of the resin container 102, and the fourth switch 108 to the sewage outlet of the soft water system.

[0096] Specifically, the third operating mode is the salt absorption and regeneration mode. By injecting high-concentration brine in the opposite direction to the water production direction, the degraded ion exchange resin is regenerated, restoring its softening capacity. In this third operating mode, the water softening system mainly includes two control steps: generating brine and injecting brine.

[0097] In the brine generation control step, the control valve controls the fifth switch 109 to enter the open state, allowing filtered water to flow into the water tank 104 and continuously accumulate in the water tank 104 until the water in the water tank 104 reaches a certain amount. Then, the control valve controls the first water pump 112 to start, drawing a certain flow rate of filtered water from the water tank 104 into the brine generation device 103 along direction 5 as needed, thereby generating a brine solution of a specific concentration. It should be noted that this embodiment does not limit the concentration of the generated brine solution and can be adaptively configured according to the needs of the actual application scenario. The amount of water drawn by the first water pump 112 and the second water pump 113 can be controlled by setting the magnitude of the drive signals of the first water pump 112 and the second water pump 113.

[0098] During the brine injection step, the control valve activates the sixth switch 110. It should be noted that the inlet of the sixth switch 110 at this time is connected to the inlet in the direction of the outlet of the brine generating device 103. The control valve also activates the second pump 113, drawing brine generated from the brine generating device 103 into the resin container 102. The seventh switch 111 acts as a backflow preventer, preventing brine from flowing back from the outlet of the resin container 102 into the brine generating device 103. When the second pump 113 is activated, brine flows into the resin container 102 from the outlet along direction 4 and from the inlet along direction 3. As the brine flows through the resin channels of the resin container 102, it comes into contact with the degraded resin along the way, restoring its softening ability. The brine is then discharged as wastewater through the wastewater outlet of the soft water system.

[0099] In a preferred embodiment, in the third operating mode, the water flow rate of the first water pump 112 and the water flow rate of the second water pump 113 are kept consistent, thereby achieving a balance between the inlet and outlet water flow rates of the brine generating device 103, preventing the accumulation of brine in the brine generating device 103 and affecting the concentration of the brine generated in subsequent brine generating steps.

[0100] The water pump design and brine generation device design in this embodiment enable instant brine generation without the need for a cavity to store high-concentration brine. This facilitates a compact overall design while maintaining a dry salt tank inside the brine generation device 103, keeping the entire device cleaner.

[0101] In one embodiment, the brine generating device 103 includes at least one salt dissolving channel arranged laterally within the brine generating device.

[0102] In practical applications, due to the horizontal arrangement of the salt dissolving channel, the liquid flows through the channel in a generally horizontal direction. This allows the liquid to fully contact the regenerated salt within the extended distance of the channel, forming a regenerated salt solution with a certain concentration. Furthermore, the concentration of the regenerated salt solution can be controlled by adjusting the flow rate, temperature, and length of the salt dissolving channel entering the salt solution generation device.

[0103] Specifically, the salt solution generating device 103 in this embodiment can be a single-layer salt dissolving channel structure or a multi-layer salt dissolving channel structure. This embodiment does not limit the salt dissolving channel structure of the salt solution generating device 103, and it can be adapted to the needs of the actual application scenario.

[0104] In one embodiment, if the system control command is used to implement the fourth working mode, the controller controls the corresponding water circuit switch to the open state and controls the corresponding power component to the start state, so that the water flows back into the resin container according to the preset flow rate, so as to slowly wash the resin container in reverse.

[0105] like Figure 5 As shown, if the system control command is used to implement the fourth working mode, the controller controls the fourth switch 108, the fifth switch 109, the sixth switch 110, and the seventh switch 111 to be in the open state, controls the second water pump 113 to be in the start state, controls the other switches to be in the closed state, and controls the first water pump 112 to be in the stop state, so that the water flows from the inlet of the soft water system through the pre-filter 101, the fifth switch 109, the inlet of the water tank 104, the second outlet of the water tank 104, the sixth switch 110, the second water pump 113, the seventh switch 111, the outlet of the resin container 102, the inlet of the resin container 102, and the fourth switch 108 to the sewage outlet of the soft water system.

[0106] Specifically, the fourth working mode is the slow washing mode. In the slow washing mode, the salt that is not fully utilized in the resin container 102 can be reused, and the hardness ions replaced by the high concentration of salt solution can be carried out, thereby realizing the full utilization of solid salt and the full regeneration of ion exchange resin in the resin container 102.

[0107] The principle of the fourth working mode in this embodiment is as follows: the purified water after passing through the pre-filter 101 flows directly from the second outlet of the water tank 104 through the sixth switch 110 and the seventh switch 111 to the outlet of the resin container 102. In the fourth working mode, only the second water pump 113 is started. At this time, the sixth switch 110 opens the inlet connected to the second outlet of the water tank 104, so that the filtered water bypasses the brine generating device 103 and flows directly into the outlet of the resin container 102 in direction 6. The replaced hardness ions are carried out along the water flow direction, and the underutilized salt is combined to regenerate the resin. Finally, the wastewater is discharged through the sewage outlet of the soft water system.

[0108] This embodiment, through the design of the slow wash mode and water circuit, can ensure the full utilization of solid salt and the full regeneration of resin in resin container 102, which can greatly improve the regeneration rate of resin regeneration and the softening efficiency of water in the soft water system.

[0109] In one embodiment, such as Figure 6 As shown, the water tank 104 also includes a liquid level sensor, which is disposed on the inner wall of the water tank 104. It should be noted that this embodiment does not limit the specific location of the liquid level sensor; it can be adaptively set according to the preset liquid level threshold requirements in the actual application scenario.

[0110] If the liquid level in water tank 104 is lower than the preset liquid level threshold, the controller controls the fifth switch 109 to the open state, controls other switches to the closed state, and controls all water pumps to the stop state, so that water flows from the inlet of the soft water system through the pre-filter 101, the fifth switch 109, and the inlet of water tank 104 to water tank 104 until the liquid level in water tank 104 is greater than or equal to the preset liquid level threshold.

[0111] Specifically, by setting a liquid level sensor, this embodiment can ensure that the water volume in the water tank 104 can meet the control requirements of the water pump flow rate before entering the third or fourth working mode.

[0112] If the liquid level in water tank 104 is greater than or equal to the preset liquid level threshold, and the system control command is used to implement the third working mode, the controller controls the fourth switch 108, the fifth switch 109, the sixth switch 110, and the seventh switch 111 to be in the open state, controls the other switches to be in the closed state, and controls the first water pump 112 and the second water pump 113 to be in the start state, so that the water flows from the first outlet of water tank 104 through the first water pump 112, the inlet of brine generating device 103, the outlet of brine generating device 103, the sixth switch 110, the second water pump 113, the seventh switch 111, the outlet of resin container 102, the inlet of resin container 102, and the fourth switch 108 to the sewage outlet of the soft water system at a preset flow rate.

[0113] If the liquid level in water tank 104 is greater than or equal to the preset liquid level threshold, and the system control command is used to implement the fourth working mode, the controller controls the fourth switch 108, the fifth switch 109, the sixth switch 110, and the seventh switch 111 to the open state, controls the second water pump 113 to the start state, controls the other switches to the closed state, and controls the first water pump 112 to the stop state, so that the water flows from the second outlet of water tank 104 through the sixth switch 110, the second water pump 113, the seventh switch 111, the outlet of resin container 102, the inlet of resin container 102, and the fourth switch 108 to the sewage outlet of the soft water system.

[0114] Specifically, the control of the switching devices and the water pump in different working modes in this embodiment can refer to the control process of the corresponding working mode in the previous embodiment, which will not be repeated here.

[0115] Specifically, in this embodiment, during the actual operation, the regeneration step of the resin container 102 requires the water volume in the water tank 104 to reach a certain threshold before the water pump is controlled to extract water according to a preset flow rate and preset flow rate. This embodiment does not limit the preset flow rate and preset flow rate, and can be adaptively configured according to the needs of the actual application scenario to maximize resin regeneration efficiency and stabilize the brine concentration.

[0116] In one embodiment, such as Figure 6 As shown, the water softening system in this embodiment further includes an eighth switch 114, through which the outlet of the pre-filter 101 is connected to the outlet of the water softening system. The eighth switch 114 in this embodiment can be a solenoid valve. It should be noted that this embodiment does not limit the specific type of the eighth switch, and it can be configured according to the needs of the actual application scenario.

[0117] Specifically, this embodiment also includes an eighth switch 114 that is directly connected to the outlet of the pre-filter 101 and the outlet of the soft water system. In this specific embodiment, if the system control command is used to implement the first working mode, the controller controls the eighth switch 114 to be in the closed state.

[0118] If the system control command is used to implement the second working mode, the third working mode or the fourth working mode, the controller controls the eighth switch 114 to be in the open state, so that the water flows from the inlet of the soft water system through the pre-filter 101 and the eighth switch 114 to the outlet of the soft water system.

[0119] Specifically, in this embodiment, the water softening system can control the eighth switch 114 to open during the backwashing mode, salt absorption and regeneration mode, and slow wash mode of the resin container 102. This ensures that the water softening system can continuously supply filtered water to the outlet, avoiding disruption to the normal water supply process of the water softener. It should be noted that the water supplied by the water softening system at this time is filtered water that has undergone preliminary purification by the pre-filter 101.

[0120] In summary, this embodiment provides a water softening system. Through the design of a salt absorption regeneration mode and a slow washing mode, it can effectively improve the utilization efficiency of solid salt in the brine generation device and the full regeneration of ion exchange resin in the resin container. Furthermore, during the control process, the plug-flow water flow design can effectively reduce the space occupied by the water softening system, improve the full contact between water and salt in the brine generation device, stabilize the brine concentration, generate better brine, increase the contact area between water and resin in the resin container, enhance the ion exchange capacity of the resin, fully filter out hardness ions in the water, and improve the performance of water softening.
