Description

Technical Field

[0001] This utility model relates to a water softener, and more particularly to a water softener capable of softening raw water (or tap water) to obtain softened water. This utility model further relates to a control valve assembly for a water softener, which, when in the softening operating position, controls a larger flow rate of raw water to be supplied to the softening device of the water softener, thereby allowing a larger flow rate of raw water to be softened. Background Technology

[0002] As people's living standards improve and they place greater emphasis on health, their demands for the quality of drinking water are also increasing. However, in many countries, especially developing countries, tap water sources are often groundwater or surface water with high hardness, which is provided to users after purification and disinfection. High-hardness tap water can easily damage the skin's protective layer, leading to dry skin and even skin allergies. Furthermore, high-hardness tap water may affect the cleansing effectiveness of skincare products and the cosmetic effects of makeup. Therefore, the user experience is poor when using high-hardness tap water to wash the face. Water with lower hardness, such as softened water obtained by softening tap water, is less irritating and gentler on the skin, making it more suitable for bathing, cleansing, and cosmetic purposes. For example, it can be used when cleansing the face.

[0003] Chinese utility model patent application CN200820169873.5 discloses a multifunctional water softening valve, which includes a valve body, a valve core, and an ejector. The valve body has multiple openings for water to flow in or out. The valve core controls the direction of water flow, and the ejector allows brine to flow from the brine container into the softening tank to wash away resin and other softening materials, and allows water from the valve body's water inlet to enter the brine container to replenish the water in the brine container. As shown in Figure 8, when the multifunctional water softening valve provided by this patent controls the water softener to soften raw water, the raw water flows from through hole 25 into through hole 19, and then flows to the softening tank. After being softened by the softening material in the softening tank, the resulting softened water flows through through hole 24, blind hole 28, and through hole 18 to the softened water outlet. Correspondingly, when the multi-functional softening valve provided by this patent controls the water softener to soften raw water, the water flow rate is determined by the area of ​​the through hole 25, through hole 19, through hole 24, blind hole 28, and through hole 18 of the overlapping portion of the moving valve plate 4 and the fixed valve plate 5. However, the structure of the multi-functional softening valve provided by this patent is too complex, with numerous through holes of irregular shape. Furthermore, the blind holes 28 of the through holes are distributed in the second and third layers (or second and third rings) of the fluid control surface from the inside out, while the through holes 18 are distributed in the third layer (or third ring). The third layer is only used by the through holes 18; the other areas of the third layer do not participate in water flow. Some through holes, such as through holes 19 and 18, although designed to occupy a large area (occupying two equal parts of the fluid control surface, with the entire fluid control surface of the moving valve plate 4 and the fixed valve plate 5 designed with nine equal parts), only a small portion actually participates in the flow during the softening process. The overlapping area of ​​the moving valve plate 4 and the fixed valve plate 5 is only one equal division. This results in the following issues with the multi-functional water softening valve provided by this patent: during water softening, the area of ​​the through holes 19, 24, and 18 on the fixed valve plate (openings formed on the flow control surface of the fixed valve plate), especially the overlapping areas of through holes 25 and 19, blind holes 28 and 24, and blind holes 28 and 18 (openings formed on the flow control surface of the fixed valve plate), which determine the flow rate, is too small as a percentage of the total flow control surface area of ​​the fixed valve plate. This significantly affects the flow rate of the water softener when softening raw water. To achieve the required flow rate through this multi-functional water softening valve, its volume must be increased, resulting in a larger size and inconvenience in use. A larger size also requires a thicker valve body wall to ensure stability under water pressure, directly increasing production costs. Furthermore, regardless of whether the moving valve disc of a multi-functional softening valve is made of metal or ceramic, an excessively large size will lead to a decrease in the yield rate during manufacturing. In particular, when the moving valve disc of a multi-functional softening valve is made of ceramic, the larger its size, the more prone it is to cracking, and the service life is significantly reduced.In addition, in order to achieve a continuous supply of raw water in the regeneration or flushing work position, the multi-functional softening valve provided by this patent sets the through hole 18 of the fixed valve plate in the outer ring (or the third ring), which further reduces the effective water passage area of ​​the entire fixed valve plate.

[0004] Therefore, existing planar control valves used in water softeners with continuous water supply functions (supplying softened water during softening, raw water during softening material regeneration, raw water during softening material rinsing, and raw water during brine tank replenishment) all have their guide holes distributed in the fixed valve plate with two or more turns. This results in low utilization of the flow control surface and small flow rate, necessitating their design and manufacturing into larger sizes. The larger size of the planar control valve not only leads to lower yield rates and higher costs during manufacturing but also reduces its lifespan. Furthermore, the larger size of the planar control valve further increases the size of the water softener, resulting in it occupying a larger indoor space. Summary of the Invention

[0005] The main advantage of this utility model is that it provides a water softener, wherein the control valve group of the water softener has a completely new spatial structure, and the control valve group of the water softener can control the water softener to realize the functions of co-current or counter-current regeneration of softening material, replenishing softened water to the brine tank, back-rinsing softening material, and forward-rinsing softening material.

[0006] Another advantage of this invention is that it provides a water softener in which the control valve assembly overcomes the design bias of existing planar control valves, making the through holes for softened water supply located on the water flow control surface of the fixed valve plate arranged in a single loop. This allows the planar control valve of the control valve assembly of this invention to significantly improve the utilization rate of the water flow control surface of its fixed valve plate.

[0007] Another advantage of this invention is that it provides a water softener in which the control valve assembly is configured to significantly increase the proportion of the cross-sectional area (area of ​​the opening of the flow control surface of the fixed valve plate) of the channel used for raw water inflow and softened water outflow when the raw water is softened.

[0008] Another advantage of this invention is that it provides a water softener in which the control valve assembly forms two parallel soft water supply channels, and the inflow channel supplying raw water to the softening device of the water softener occupies two equal parts of the control surface. This makes the proportion of the total cross-sectional area of ​​the inflow channel supplying raw water to the softening device and the total cross-sectional area of ​​the outflow channel of the softened water to the total area of ​​the control surface of the valve plate larger when the water softener softens the raw water.

[0009] Another advantage of this invention is that it provides a control valve assembly for a water softener, which can provide relatively larger channels (openings formed on the flow control surface of the fixed valve plate) for raw water inflow and softened water outflow when controlling the softening of raw water. In particular, the channels for raw water supply and the through holes for softened water supply on the flow control surface of the fixed valve plate of this invention are arranged in a single loop, thereby further significantly improving the utilization rate of the flow control surface of the fixed valve plate.

[0010] Another advantage of this invention is that it provides a control valve assembly for a water softener that can prevent the flow of raw water to the outlet during the regeneration and flushing operation.

[0011] Other objects and features of this utility model will be fully demonstrated by the following detailed description.

[0107] Refer to the attached diagram in the instruction manual. Figures 1 to 3C The present invention describes a water softener comprising a control valve assembly 1 and a softening device 20. The softening device 20 has a first connecting opening 201 and a second connecting opening 202, allowing raw water to flow in through the first connecting opening 201 and softened water (or soft water) to flow out through the second connecting opening 202. The control valve assembly 1 is configured to control the flow of water, such as controlling the supply of raw water to the softening device 20 and controlling the softening device 20 to treat the raw water and produce or supply softened water. It is understood that the control valve assembly 1 of the present invention is connected to a raw water source, such as a tap water pipe. In other words, the control valve assembly 1 controls the supply of raw water to the softening device 20.

[0108] As shown in the attached image. Figures 1 to 3C As shown, exemplarily, the softening device 20 of the water softener according to an embodiment of the present invention includes a housing 21 and a softening material 23. The housing 21 has a first opening 211, a second opening 213, and a receiving portion 212 extending from the first opening 211 to the second opening 213. The softening material 23 is disposed within the receiving cavity 2120 of the receiving portion 212 of the housing 21. The first connecting opening 201 and the second connecting opening 202 of the softening device 20 are respectively connected to the receiving cavity 2120 of the receiving portion 212 of the housing 21, so that raw water can flow in through the first connecting opening 201, and softened water (or soft water) softened by the softening material 23 can flow out through the second connecting opening 202. (See attached figures) Figures 1 to 3C As shown, in the water softener according to this embodiment, the first opening 211 of the softening device 20 forms the first connecting opening 201, and the second opening 213 forms the second connecting opening 202. It can be understood that the first connecting opening 201 and the second connecting opening 202 of the softening device 20 can also be arranged on the same side through a central tube.

[0109] As shown in the attached image. Figure 3B As shown, when the water softener according to this embodiment of the invention is in softening treatment, soft water replenishment, or forward rinsing (forward washing) treatment, the water flows sequentially through the first connecting opening 201, the softening material 23, and the second connecting opening 202. (See attached figures.) Figure 3CAs shown, when the water softener according to this utility model embodiment is in the reverse flushing (backwashing) process, the water flows sequentially through the second connecting opening 202, the softening material 23 and the first connecting opening 201.

[0110] As shown in the attached image. Figure 3B As shown, when the water softener according to this embodiment of the present invention is in the co-current regeneration process, under the control of the control valve group 1, the regeneration solution, such as a salt solution (sodium chloride solution), flows to the first connecting opening 201 of the softening device 20 of the water softener of the present invention. The regeneration solution flows sequentially through the first connecting opening 201, the softening material 23, and the second connecting opening 202, and in this process, the softening material 23 of the water softener of the present invention undergoes co-current regeneration treatment. The waste liquid generated during the co-current regeneration process of the softening material 23 of the water softener of the present invention is discharged from the second connecting opening 202. The co-current regeneration of the present invention means that when the softening device 20 is in the regeneration process, the flow direction of the regeneration solution in the softening device 20 is basically the same as the flow direction of the water in the softening device 20 when the softening device 20 is used to soften the raw water.

[0111] As shown in the attached image. Figure 3C As shown, when the water softener according to this embodiment of the present invention is subjected to countercurrent regeneration, under the control of the control valve group 1, the regeneration solution, such as a salt solution (sodium chloride solution), flows to the second connecting opening 202 of the softening device 20 of the water softener of the present invention. The regeneration solution flows sequentially through the second connecting opening 202, the softening material 23, and the first connecting opening 201, and in this process, the softening material 23 of the water softener of the present invention undergoes countercurrent regeneration. The waste liquid generated during the countercurrent regeneration of the softening material 23 of the water softener of the present invention is discharged from the first connecting opening 201. The countercurrent regeneration of the present invention means that during the regeneration process of the softening device 20, the flow direction of the regeneration solution in the softening device 20 is substantially opposite to the flow direction of the water in the softening device 20 when the softening device 20 softens the raw water.

[0112] As shown in the attached image. Figures 2 to 6LAs shown, the control valve group 1 of the water softener according to this embodiment of the present invention includes a main control valve 10 and a regeneration control valve 30. The main control valve 10 further includes a main valve body 11 and a main valve core 12. The main valve body 11 forms a valve cavity 110, a first opening 1101, a second opening 1102, a water outlet 1104, a water inlet 1106, and a sewage outlet 1113. The main valve core 12 is disposed in the valve cavity 110. The first opening 1101 of the main valve body 11 is adapted to communicate with the first communication opening 201 of the softening device 20. The second opening 1102 of the main valve body 11 is adapted to communicate with the second communication opening 202 of the softening device 20. The water inlet 1106 of the main valve body 11 is adapted to communicate with the raw water source (e.g., a tap water pipe).

[0113] Attached image Figures 2 to 4 , Figures 6M to 6O and Figures 10 to 11I As shown, the regeneration control valve 30 of the control valve group 1 of the water softener according to the embodiment of the present invention includes a regeneration valve body 31 and a regeneration valve core 32, wherein the regeneration valve body 31 forms a regeneration valve cavity 310, a first jet opening 1111 and a second jet opening 1112, wherein the regeneration valve core 32 is disposed in the regeneration valve cavity 310, wherein the regeneration valve cavity 310 of the regeneration valve body 31 is adapted to communicate with the valve cavity 110 of the main valve body 11, and the regeneration valve cavity 310 of the regeneration valve body 31 is connected to the raw water source (e.g., tap water pipe) through the valve cavity 110 of the main valve body 11 and the water inlet 1106.

[0114] As shown in the attached image. Figures 10 to 11I As shown, the regeneration control valve 30 of the control valve assembly 1 of the water softener according to this embodiment of the present invention further includes an ejector 18, wherein the ejector 18 has an outlet 182 adapted to communicate with the first jet opening 1111 of the regeneration valve body 31, an inlet 183 adapted to communicate with the second jet opening 1112 of the regeneration valve body 31, and a brine inlet 181 respectively connected to the outlet 182 and the inlet 183. When water, such as tap water, flows from the outlet 182 of the ejector 18 to the inlet 183 of the ejector 18, a negative pressure appears at the brine inlet 181 of the ejector 18, so that the regeneration solution can flow from the brine inlet 181 of the ejector 18 to the inlet 183 of the ejector 18. Accordingly, the salt intake port 181 of the ejector 18 is connected to the ejection outlet 182 and the ejection inlet 183 of the ejector 18.

[0115] As shown in the attached image. Figure 1 , Figure 2 and Figure 10As shown, the water softener according to this embodiment of the present invention further includes a brine suction pipe 184 and a brine tank 185, wherein one end of the brine suction pipe 184 is connected to the brine suction port 181, and the other end of the brine suction pipe 184 is connected to the brine tank 185, so that brine can be supplied to the brine suction port 181 through the brine suction pipe 184, or water can flow from the brine suction port 181 and through the brine suction pipe 184 to the brine tank 185 to replenish the brine tank 185.

[0116] As shown in the attached image. Figures 17A to 17C and Figure 23A As shown, according to an embodiment of the present invention, the main control valve 10 of the control valve assembly 1 of the water softener has a softening working position, and the regeneration control valve 30 has a flow-stopping working position. When the main control valve 10 is in the softening working position, the main valve core 12 of the main control valve 10 forms a first softening flow channel 10011, a second softening flow channel 10012, and a third softening flow channel 10013, wherein the first softening flow channel 10011 respectively... The main valve body 11 is connected to the inlet 1106 and the first opening 1101. The second softening channel 10012 is connected to the second opening 1102 and the outlet 1104 respectively. The third softening channel 10013 is connected to the second opening 1102 and the outlet 1104 respectively. When the regeneration control valve 30 is in the stop-flow working position, the regeneration control valve 30 can prevent water from flowing from the main control valve 10 to the regeneration control valve 30. Accordingly, when the main control valve 10 is in the softening working position and the regeneration control valve 30 is in the flow-stopping working position, the raw water, under water pressure, flows in from the inlet 1106 of the main valve body 11 of the main control valve 10, flows through the first softening channel 10011 to the first opening 1101 of the main valve body 11, and further flows into the softening device 20 from the first connecting opening 201 of the softening device 20. After being softened by the softening device 20, the raw water... Softened water flows out from the second connecting opening 202 of the softening device 20 and further into the second opening 1102. Since the second opening 1102 and the outlet 1104 are connected through the second softening channel 10012 and the third softening channel 10013 respectively, the softened water flowing into the second opening 1102 flows through the second softening channel 10012 and the third softening channel 10013 to the outlet 1104 and is supplied. It can be understood that when the main control valve 10 of the control valve group 1 of the water softener according to the present invention is controlled to be in the softening working position and the regeneration control valve 30 is controlled to be in the flow-stopping working position, the water softener of the present invention is controlled to be in its softening working state.

[0117] It is worth noting that the vast majority, if not all, control valves used in existing water softeners rely on a single softening channel for both softened water flow and supply. Given the same volume, this single softening channel limits the flow rate of the control valve, and the flow rate of the softened water further limits the overall softening speed of the water softener. The main control valve 10 of the control valve assembly 1 in this invention increases the outflow rate of softened water by adding a softening channel, while simultaneously increasing the cross-sectional area of ​​the raw water supply channel (first softening channel 10011), thereby improving the overall softening speed of the water softener.

[0118] As shown in the attached image. Figures 18A to 18C and Figure 23BAs shown, according to an embodiment of the present invention, the main control valve 10 of the control valve assembly 1 of the water softener has a backflow discharge working position, and the regeneration control valve 30 has a backflow regeneration working position. When the main control valve 10 is in the backflow discharge working position and the regeneration control valve 30 is in the backflow regeneration working position, the main valve core 12 and the regeneration valve core 32 of the control valve assembly 1 form a first backflow regeneration channel 10021, a second backflow regeneration channel 10022, and a third backflow regeneration channel. The first countercurrent regeneration channel 10021 is connected to the inlet 1106 of the main valve body 11 and the first jet opening 1111 of the regeneration valve body 31, the second countercurrent regeneration channel 10022 is connected to the second jet opening 1112 of the regeneration valve body 31 and the second opening 1102 of the main valve body 11, and the third countercurrent regeneration channel 10023 is connected to the first opening 1101 and the sewage outlet 1113 of the main valve body 11. Correspondingly, when the main control valve 10 is in the counter-current sewage discharge position and the regeneration control valve 30 is in the counter-current regeneration position, the raw water, under water pressure, flows in from the inlet 1106 of the main valve body 11 of the main control valve 10, flows through the first counter-current regeneration channel 10021 to the first jet opening 1111 of the regeneration valve body 31, and then flows into the jet outlet 182 of the ejector 18. After being jetted by the ejector 18, it mixes with the brine (such as sodium chloride solution) from the brine suction port 181 to form a regeneration solution. The regeneration solution flows through the jet inlet 183 of the ejector 18. The regeneration solution enters through the second jet opening 1112 of the regeneration valve body 31, and then flows into the second opening 1102 of the main valve body 11 through the second countercurrent regeneration channel 10022. The regeneration solution flows into the softening device 20 from the second connecting opening 202, regenerating the water treatment material or mechanism of the softening device 20, such as softening resin. After regeneration, the wastewater generated flows out from the first connecting opening 201 of the softening device 20, and then flows out sequentially through the first opening 1101 of the main valve body 11, the third countercurrent regeneration channel 10023, and the drain opening 1113. It can be understood that when the main control valve 10 of the control valve group 1 of the water softener according to the present invention is controlled to be in the countercurrent drain position and the regeneration control valve 30 is controlled to be in the countercurrent regeneration position, the water softener of the present invention is controlled to be in its countercurrent regeneration working state. It is worth noting that the wastewater generated after regeneration flows out through the discharge outlet 1113. Countercurrent regeneration, compared to cocurrent regeneration, can save on salt usage. Understandably, countercurrent regeneration is also commonly used in floating bed softening systems in industrial water treatment, which is more suitable for softening large flow rates and high hardness water.

[0119] As shown in the attached image. Figure 19A , Figure 19Band Figure 23C As shown, according to an embodiment of the present invention, the main control valve 10 of the control valve assembly 1 of the water softener has a downstream sewage discharge working position, and the regeneration control valve 30 has a downstream regeneration working position. When the main control valve 10 is in the downstream sewage discharge working position and the regeneration control valve 30 is in the downstream regeneration working position, the main valve core 12 and the regeneration valve core 32 of the control valve assembly 1 form a first downstream regeneration channel 10024, a second downstream regeneration channel 10025, and a third downstream regeneration channel. Channel 10026, wherein the first downstream regeneration channel 10024 is connected to the inlet 1106 of the main valve body 11 and the first jet opening 1111 of the regeneration valve body 31, the second downstream regeneration channel 10025 is connected to the second jet opening 1112 of the regeneration valve body 31 and the first opening 1101 of the main valve body 11, and the third downstream regeneration channel 10026 is connected to the second opening 1102 of the main valve body 11 and the sewage outlet 1113. Correspondingly, when the main control valve 10 is in the downstream sewage discharge position and the regeneration control valve 30 is in the downstream regeneration position, the raw water, under water pressure, flows in from the inlet 1106 of the main valve body 11 of the main control valve 10, flows through the first downstream regeneration channel 10024 to the first jet opening 1111 of the regeneration valve body 31, and then flows into the jet outlet 182 of the ejector 18. After being jetted by the ejector 18, it mixes with the brine (such as sodium chloride solution) from the brine suction port 181 to form a regeneration solution. The regeneration solution flows through the jet inlet 183 of the ejector 18. The regeneration solution enters through the second jet opening 1112 of the regeneration valve body 31, and then flows into the first opening 1101 of the main valve body 11 through the second downstream regeneration channel 10025. The regeneration solution flows into the softening device 20 from the first connecting opening 201, regenerating the water treatment material or mechanism of the softening device 20, such as softening resin. After regeneration, the wastewater generated flows out from the second connecting opening 202 of the softening device 20, and then flows out sequentially through the second opening 1102 of the main valve body 11, the third downstream regeneration channel 10026, and the drain opening 1113. It can be understood that when the main control valve 10 of the control valve group 1 of the water softener according to the present invention is controlled to be in the downstream drain position and the regeneration control valve 30 is controlled to be in the downstream regeneration position, the water softener of the present invention is controlled to be in its downstream regeneration working state. In the industrial sector, water treatment materials in water softeners are relatively large, and are often regenerated using co-current regeneration, such as softening resin. Co-current regeneration is generally used in fixed-bed regeneration methods. It does not disturb the resin stratification, which helps to achieve a stable softening effect more quickly when softened water is first supplied after regeneration.

[0120] Therefore, the main control valve 10 of the control valve assembly 1 of the water softener according to this utility model embodiment has a counter-current sewage discharge working position and a co-current sewage discharge working position, and the regeneration control valve 30 has a counter-current regeneration working position and a co-current regeneration working position. This allows the control valve assembly 1 to be flexibly used in regeneration methods that require counter-current regeneration or co-current regeneration. This means that users only need to purchase one control valve assembly 1 of the water softener according to this utility model embodiment, which can be used as a counter-current regeneration control valve or a co-current regeneration control valve in specific use, avoiding the disadvantage of needing to purchase two control valves separately.

[0121] As shown in the attached image. Figure 20 and Figure 23D As shown, the main control valve 10 of the control valve group 1 of the water softener according to this embodiment of the present invention further has a backwash working position. When the main control valve 10 is in the backwash working position and the regeneration control valve 30 is in the stop-flow working position, the main valve core 12 of the main control valve 10 forms a first backwash flow channel 10031 and a second backwash flow channel 10032. The first backwash flow channel 10031 is connected to the water inlet 1106 and the second opening 1102 of the main valve body 11, respectively. The second backwash flow channel 10032 is connected to the first opening 1101 and the drain opening 1113 of the main valve body 11, respectively. Accordingly, when the main control valve 10 is in the backwash working position and the regeneration control valve 30 is in the stop-flow working position, raw water flows in from the inlet 1106 of the main valve body 11 of the main control valve 10 under water pressure, flows through the first backwash channel 10031 to the second opening 1102 of the main valve body 11, so that the raw water flows through the second opening 1102 to the second connecting opening 202 of the softening device 20 to backwash the softening material of the softening device 20. The resulting sewage further flows out through the first connecting opening 201 and through the first opening 1101 and the second backwash channel 10032 to the drain opening 1113. When the main control valve 10 of the control valve group 1 of the water softener according to the present invention is controlled to be in the backwash working position and the regeneration control valve 30 is controlled to be in the stop-flow working position, the water softener of the present invention is controlled to be in its backwash working state.

[0122] As shown in the attached image. Figures 17A to 17C , Figure 21 and Figure 23EAs shown, according to an embodiment of the present invention, the regeneration control valve 30 of the control valve assembly 1 of the water softener further has a water replenishment working position. When the main control valve 10 is in the softening working position and the regeneration control valve 30 is in the water replenishment working position, the main valve core 12 and the regeneration valve core 32 of the control valve assembly 1 form the first softening flow channel 10011, the second softening flow channel 10012, the third softening flow channel 10013, and a water replenishment flow channel 10041. The first softening flow channel 10011 is divided into... The second softening channel 10012 is connected to the second opening 1102 and the outlet 1104 of the main valve body 11, respectively. The third softening channel 10013 is connected to the second opening 1102 and the outlet 1104 of the main valve body 11, respectively. The water replenishment channel 10041 is connected to the second opening 1102 of the main valve body 11 and the second jet opening 1112 of the regeneration valve body 31, respectively. Accordingly, when the main control valve 10 is in the softening working position and the regeneration control valve 30 is in the water replenishment working position, raw water flows in from the inlet 1106 of the main valve body 11 of the main control valve 10 under water pressure, flows through the first softening channel 10011 to the first opening 1101 of the main valve body 11, so that the raw water flows through the first opening 1101 to the first connecting opening 201 of the softening device 20, so that it is softened to obtain softened water. The obtained softened water further flows out through the second connecting opening 202 of the softening device 20 and flows into the second opening 1102 of the main valve body 11. The softened water flowing into the second opening 1102 of the main valve body 11 is divided into three paths, the first path of softened water... The water flows through the replenishment channel 10041 to the second jet opening 1112 of the regeneration valve body 31, and then sequentially flows through the jet inlet 183, the brine inlet 181 and the brine suction pipe 184 of the jet injector 18 into the brine tank 185 for replenishment. The second stream of softened water flows through the second softening channel 10012 to the outlet 1104 of the main valve body 11, and the third stream of softened water flows through the third softening channel 10013 to the outlet 1104 of the main valve body 11. Softened water is supplied to the outlet 1104 of the main valve body 11 through the parallel operation of the second softening channel 10012 and the third softening channel 10013, so that softened water can continue to be supplied when the water softener of this utility model is controlled to be in its softened water replenishment working state. When the main control valve 10 of the control valve assembly 1 of the water softener according to this embodiment is controlled to the softening working position and the regeneration control valve 30 is controlled to the water replenishment working position, the water softener of this invention is controlled to be in its softened water replenishment working state. Furthermore, since the water replenished to the brine tank has already been softened, the water replenished to the brine tank is soft water. Replenishing with softened water helps reduce the hardness of the regeneration solution itself, and helps save salt when regenerating the softening material.

[0123] As shown in the attached image. Figure 22 and Figure 23F As shown, the main control valve 10 of the control valve group 1 of the water softener according to this embodiment of the present invention further has a forward wash working position. When the main control valve 10 is in the forward wash working position and the regeneration control valve 30 is in the stop flow working position, the main valve core 12 of the main control valve 10 forms a first forward wash flow channel 10051 and a second forward wash flow channel 10052. The first forward wash flow channel 10051 is connected to the water inlet 1106 and the first opening 1101 of the main valve body 11, respectively. The second forward wash flow channel 10052 is connected to the second opening 1102 and the drain opening 1113 of the main valve body 11, respectively. Correspondingly, when the main control valve 10 is in the forward washing position and the regeneration control valve 30 is in the stop-flow position, the raw water flows in from the inlet 1106 of the main valve body 11 of the main control valve 10 under water pressure, flows through the first forward washing channel 10051 to the first opening 1101 of the main valve body 11, so that the raw water flows through the first opening 1101 to the first connecting opening 201 of the softening device 20 to perform forward rinsing of the softening material of the softening device 20. The resulting sewage further flows out through the second connecting opening 202 and flows through the second opening 1102 and the second forward washing channel 10052 to the sewage outlet 1113. When the main control valve 10 of the control valve group 1 of the water softener according to the present invention is controlled to be in the forward washing working position and the regeneration control valve 30 is controlled to be in the flow stop working position, the water softener of the present invention is controlled to be in its forward washing working state.

[0124] Therefore, compared with existing control valves for water softeners, the control valve assembly 1 of the water softener according to this embodiment of the present invention has a completely new structure. It can not only control and increase the softening speed of the entire water softener at the softening working position, but also select co-current or counter-current regeneration during the regeneration of the softening material and control the supply of softened water when replenishing the brine tank 185, thereby meeting the operation requirements of the water softener under different working conditions. The main control valve 10 and the regeneration control valve 30 can have different valve body sizes. Since the regeneration control valve 30 only controls the flow of regenerated brine and replenished soft water, and since the flow of regenerated brine and replenished soft water is relatively small compared to the softening flow rate of the main control valve 10, and since both backwashing and forward washing are performed by the main control valve 10, and the regeneration control valve 30 does not need to participate in the backwashing and forward washing processes, the regeneration control valve 30 can use a smaller valve body and valve core, which not only saves costs but also makes the regeneration control valve 30 easier to manufacture.

[0125] As shown in the attached image. Figures 5 to 9BAs shown, the main control valve 10 of the control valve assembly 1 of the water softener according to this embodiment is a planar valve.

More preferably, the third conducting opening 3103 of the third connecting channel 503 is connected to the fourth connecting channel 504.

The fourth channel 104 is connected to the outlet 1104 through the fifth connecting channel 505. The fifth channel 105 is connected to the outlet 1104. Preferably, the fourth channel 104 is connected to the fifth channel 105 and the outlet 1104 through the fifth connecting channel 505.

[0131] As shown in the attached image. Figures 7A to 9BAs shown, in this embodiment of the water softener, the main control valve 10 has a main fixed valve plate 121 whose first fluid control surface 1210 forms a central portion 12101 and an edge portion 12102 extending outward from the central portion 12101. The first channel 101, the fifth channel 105, the third channel 103, the second channel 102 and the fourth channel 104 of the main control valve 10 are arranged clockwise in this order on the edge portion 12102 of the first fluid control surface 1210 of the main fixed valve plate 121.

Optionally, the first channel 101, the fifth channel 105, the third channel 103, the second channel 102, and the fourth channel 104 of the main control valve 10 are arranged in a counterclockwise order on the edge portion 12102 of the first fluid control surface 1210 of the main fixed valve plate 121, and the sixth channel 106, the eighth channel 108, the drain channel 1013, and the seventh channel 107 of the main control valve 10 are arranged in a counterclockwise order on the second fluid control surface 1220 of the active valve plate 122. Preferably, the first channel 101, the second channel 102, the third channel 103, the fourth channel 104, and the fifth channel 105 of the main control valve 10 are spaced apart and disposed on the first fluid control surface 1210 of the main fixed valve plate 121; the sixth channel 106, the seventh channel 107, the drain channel 1013, and the eighth channel 108 of the main control valve 10 are spaced apart and disposed on the second fluid control surface 1220 of the active valve plate 122.

[0132] As shown in the attached image. Figures 12A to 14BAs shown, in this embodiment of the water softener, the third fluid control surface 3210 of the regeneration control valve 30 of the regeneration stationary valve plate 321 forms a regeneration center portion 32101 and a regeneration edge portion 32102 extending outward from the regeneration center portion 32101. The ninth channel 109, the first jet channel 1011 and the tenth channel 1010 of the regeneration control valve 30 are arranged clockwise in this order on the regeneration edge portion 32102 of the third fluid control surface 3210 of the regeneration stationary valve plate 321. The second jet channel 1012 of the regeneration control valve 30 is arranged on the regeneration center portion 32101 of the third fluid control surface 3210 of the regeneration stationary valve plate 321. The water inlet channel 1014 and the conduction channel 1015 of the regeneration control valve 10 are arranged on the fourth fluid control surface 3220 of the regeneration moving valve plate 322. Optionally, the ninth channel 109, the first jet channel 1011, and the tenth channel 1010 of the regeneration control valve 30 are arranged in a counterclockwise order on the regeneration edge portion 32102 of the third fluid control surface 3210 of the regeneration stationary valve plate 321. Preferably, the ninth channel 109, the tenth channel 1010, the first jet channel 1011, and the second jet channel 1012 of the regeneration control valve 30 are spaced apart on the third fluid control surface 3210 of the regeneration stationary valve plate 321; the water inlet channel 1014 and the conduction channel 1015 of the regeneration control valve 30 are spaced apart on the fourth fluid control surface 3220 of the regeneration moving valve plate 322.

[0133] As shown in the attached image. Figure 16A , Figure 16B , Figures 17A to 17C and Figure 23A As shown, in this embodiment of the water softener, the active valve plate 122 of the main control valve 10 can rotate relative to the main stationary valve plate 121, thereby giving the main control valve 10 a softening working position. The regeneration active valve plate 322 of the regeneration control valve 30 can rotate relative to the regeneration stationary valve plate 321, thereby giving the regeneration control valve 30 a flow-stopping working position. When the main control valve 10 is in the softening working position, the sixth channel 106 of the main control valve 10 is connected to the first channel 101, thereby forming a connection with the inlet 11 of the main valve body 11. The first softening channel 10011, connected to the first opening 1101, and the seventh channel 107, connected to the second channel 102 and the fourth channel 104 respectively, form the second softening channel 10012, which is connected to the second opening 1102 and the outlet 1104 of the main valve body 11 respectively. The eighth channel 108, connected to the third channel 103 and the fifth channel 105 respectively, forms the third softening channel 10013, which is connected to the second opening 1102 and the outlet 1104 of the main valve body 11 respectively. (See attached diagram) Figure 16A , Figure 16B and Figure 23A As shown, when the main control valve 10 is in the softening position, the drain channel 1013 is blocked by the first fluid control surface 1210 of the main fixed valve plate 121; when the regeneration control valve 30 is in the stop position, the ninth channel 109, the tenth channel 1010, and the first jet channel 1011 are blocked by the fourth fluid control surface 3220 of the regeneration valve plate 322, the inlet channel 1014 is blocked by the third fluid control surface 3210 of the regeneration fixed valve plate 321, and the connecting channel 1015 is connected to the second jet channel 1012. Although the connecting channel 1015 is connected to the second jet channel 1012, it cannot form a flow channel that allows water to flow through. Accordingly, when the main control valve 10 is in the softening working position and the regeneration control valve 30 is in the flow-stopping working position, the raw water, under water pressure, flows in from the inlet 1106 of the main valve body 11 of the main control valve 10, flows through the first softening channel 10011 to the first opening 1101 of the main valve body 11, and further flows into the softening device 20 from the first connecting opening 201 of the softening device 20. After being softened by the softening device 20, the raw water... The softened water flows out from the second connecting opening 202 of the softening device 20 and further into the second opening 1102. Since the second opening 1102 and the outlet 1104 are connected through the second softening channel 10012 and the third softening channel 10013 respectively, the softened water flowing into the second opening 1102 flows to the outlet 1104 and is supplied through the second softening channel 10012 and the third softening channel 10013 respectively. In other words, after the raw water is softened by the softening device 20, the softened water flows out from the second connecting opening 202 of the softening device 20 and further into the second opening 1102. Then, it flows into the outlet 1104 and out through the second softening channel 10012 formed by the fourth connecting channel 504, the second channel 102, the seventh channel 107, the fourth channel 104, and the fifth connecting channel 505, and the third softening channel 10013 formed by the fourth connecting channel 504, the third channel 103, the eighth channel 108, and the fifth channel 105. Preferably, the orifice size of the sixth channel 106 of the main control valve 10 of the water softener of this utility model is adapted to the orifice size of the first channel 101, the orifice sizes of the second channel 102 and the fourth channel 104 of the main control valve 10 are adapted to the orifice size of the seventh channel 107, and the orifice sizes of the third channel 103 and the fifth channel 105 are adapted to the orifice size of the eighth channel 108, so that the water flow can flow smoothly between the corresponding channels.

[0134] As shown in the attached image. Figure 16C , Figure 16D , Figures 18A to 18C and Figure 23B As shown, in this embodiment of the water softener, the active valve plate 122 of the main control valve 10 can rotate relative to the main stationary valve plate 121, thereby giving the main control valve 10 a counter-current discharge working position. The regeneration active valve plate 322 of the regeneration control valve 30 can rotate relative to the regeneration stationary valve plate 321, thereby giving the regeneration control valve 30 a counter-current regeneration working position. When the regeneration control valve 30 is in the counter-current regeneration working position, the water inlet channel 1014 of the regeneration control valve 30 is connected to the first jet channel 1011, thereby forming connections with the water inlet 1106 of the main valve body 11 and the first jet channel 1011, respectively. The first counter-current regeneration channel 10021 is connected to the first jet opening 1111. The conducting channel 1015 is connected to the second jet channel 1012 and the tenth channel 1010, respectively, thereby forming the second counter-current regeneration channel 10022, which is connected to the second jet opening 1112 of the regeneration valve body 31 and the second opening 1102 of the main valve body 11, respectively. When the main control valve 10 is in the counter-current sewage discharge working position, the sewage discharge channel 1013 is connected to the first channel 101, thereby forming the third counter-current regeneration channel 10023, which is connected to the first opening 1101 and the sewage discharge opening 1113 of the main valve body 11, respectively. As shown in the attached figure. Figure 16C , Figure 16D and Figure 23B As shown, when the main control valve 10 is in the counter-current sewage discharge position, the seventh channel 107 is connected to the fifth channel 105, the eighth channel 108 is connected to the first channel 101, the second channel 102, the third channel 103, and the fourth channel 104 are blocked by the second fluid control surface 1220 of the active valve plate 122, and the sixth channel 106 is blocked by the first fluid control surface 1210 of the main stationary valve plate 121. When the regeneration control valve 30 is in the counter-current regeneration position, the ninth channel 109 is blocked by the fourth fluid control surface 3220 of the regeneration active valve plate 322. Although the seventh channel 107 is connected to the fifth channel 105, and the eighth channel 108 is connected to the first channel 101, a flow channel that allows water to flow cannot be formed. It is understandable that when the main control valve 10 is in the counter-current sewage discharge position and the regeneration control valve 30 is in the counter-current regeneration position, although the seventh channel 107 is connected to the fifth channel 105, the fifth channel 105 is blocked by the active valve plate 122 because the seventh channel 107 is a blind hole. Also, because the fourth channel 104 is blocked by the second fluid control surface 1220 of the active valve plate 122, the fourth channel 104 and the fifth channel 105 are respectively connected to the outlet 1104, so that no untreated water flows out of the outlet 1104.

[0135] As shown in the attached image. Figure 16E , Figure 16F , Figure 19A , Figure 19B and Figure 23C As shown, in this embodiment of the water softener, the active valve plate 122 of the main control valve 10 can rotate relative to the main stationary valve plate 121, thereby giving the main control valve 10 a downstream discharge working position. Similarly, the regeneration active valve plate 322 of the regeneration control valve 30 can rotate relative to the regeneration stationary valve plate 321, thereby giving the regeneration control valve 30 a downstream regeneration working position. When the regeneration control valve 30 is in the downstream regeneration working position, the inlet channel 1014 of the regeneration control valve 30 is connected to the first jet channel 1011, thereby forming connections with the inlet 1106 of the main valve body 11 and the regeneration valve body 31, respectively. The first jet opening 1111 is connected to the first downstream regeneration channel 10024. The guiding channel 1015 is connected to the second jet channel 1012 and the ninth channel 109, respectively, thereby forming the second downstream regeneration channel 10025, which is connected to the second jet opening 1112 of the regeneration valve body 31 and the first opening 1101 of the main valve body 11. When the main control valve 10 is in the downstream sewage discharge position, the sewage discharge channel 1013 is connected to the second channel 102, thereby forming the third downstream regeneration channel 10026, which is connected to the second opening 1102 and the sewage discharge opening 1113 of the main valve body 11. As shown in the attached figure. Figure 16E , Figure 16F and Figure 23C As shown, when the main control valve 10 is in the downstream sewage discharge position, the seventh channel 107 is connected to the first channel 101, the third channel 103, the fourth channel 104, and the fifth channel 105 are respectively blocked by the second fluid control surface 1220 of the active valve plate 122, and the sixth channel 106 and the eighth channel 108 are respectively blocked by the first fluid control surface 1210 of the main stationary valve plate 121; when the regeneration control valve 30 is in the downstream regeneration position, the tenth channel 1010 is blocked by the fourth fluid control surface 3220 of the regeneration active valve plate 322. Although the seventh channel 107 is connected to the first channel 101, it cannot form a flow channel that allows water to flow through. It is understood that when the main control valve 10 is in the downstream sewage discharge working position and the regeneration control valve 30 is in the downstream regeneration working position, the fourth channel 104 and the fifth channel 105 are respectively blocked by the second fluid control surface 1220 of the active valve plate 122, and the fourth channel 104 and the fifth channel 105 are respectively connected to the outlet 1104, so that no untreated water flows out of the outlet 1104.

[0136] As shown in the attached image. Figure 16G , Figure 16H , Figure 20 and Figure 23D As shown in the figure, in this embodiment of the water softener, the active valve plate 122 of the main control valve 10 can rotate relative to the main stationary valve plate 121, thereby giving the main control valve 10 a backwash working position. When the main control valve 10 is in the backwash working position, the sixth channel 106 of the main control valve 10 is connected to the third channel 103, thereby forming a first backwash flow channel 10031 that is connected to the water inlet 1106 and the second opening 1102 of the main valve body 11, respectively. The sewage discharge channel 1013 is connected to the first channel 101, thereby forming a second backwash flow channel 10032 that is connected to the first opening 1101 and the sewage discharge opening 1113 of the main valve body 11, respectively. Figure 16G , Figure 16H and Figure 23D As shown, when the main control valve 10 is in the backwashing position, the eighth channel 108 is connected to the fourth channel 104, the second channel 102 and the fifth channel 105 are blocked by the second fluid control surface 1220 of the active valve plate 122, and the seventh channel 107 is blocked by the first fluid control surface 1210 of the main stationary valve plate 121; when the regeneration control valve 30 is in the stop-flow position, the ninth channel 109, the tenth channel 1010 and the first jet channel 1011 are blocked by the fourth fluid control surface 3220 of the regeneration active valve plate 322, the water inlet channel 1014 is blocked by the third fluid control surface 3210 of the regeneration stationary valve plate 321, and the connecting channel 1015 is connected to the second jet channel 1012. Although the eighth channel 108 is connected to the fourth channel 104, and the conducting channel 1015 is connected to the second jet channel 1012, a flow path that allows water to flow through cannot be formed. It can be understood that when the main control valve 10 is in the backwashing position and the regeneration control valve 30 is in the stop-flow position, although the eighth channel 108 is connected to the fourth channel 104, the fourth channel 104 is blocked by the active valve plate 122 because the eighth channel 108 is a blind orifice. Furthermore, the fifth channel 105 is blocked by the second fluid control surface 1220 of the active valve plate 122. Therefore, the fourth channel 104 and the fifth channel 105 are respectively connected to the outlet 1104, resulting in no untreated water flowing out of the outlet 1104.

[0137] As shown in the attached image. Figure 16I , Figure 16J , Figures 17A to 17C , Figure 21 and Figure 23EAs shown, in this embodiment of the water softener, the regeneration control valve 30's regeneration moving valve plate 322 can rotate relative to the regeneration fixed valve plate 321, thereby giving the regeneration control valve 30 a water replenishment working position. When the main control valve 10 is in the softening working position, the sixth channel 106 of the main control valve 10 is connected to the first channel 101, thereby forming a first softening flow channel 10011 that is connected to the inlet 1106 and the first opening 1101 of the main valve body 11. The seventh channel 107 of the main control valve 10 is connected to the second channel 102 and the fourth channel 104, thereby forming a second opening 1102 and the second opening 1101 of the main valve body 11, respectively. The second softening channel 10012 is connected to the outlet 1104. The eighth channel 108 of the main control valve 10 is connected to the third channel 103 and the fifth channel 105, respectively, thus forming the third softening channel 10013, which is connected to the second opening 1102 of the main valve body 11 and the outlet 1104, respectively. When the regeneration control valve 30 is in the water replenishment position, the conduction channel 1015 of the regeneration control valve 30 is connected to the tenth channel 1010 and the second jet channel 1012, respectively, thus forming the water replenishment channel 10041, which is connected to the second opening 1102 of the main valve body 11 and the second jet opening 1112 of the regeneration valve body 31, respectively. As shown in the attached figure. Figure 16I , Figure 16J and Figure 23EAs shown, when the main control valve 10 is in the softening working position, the drain channel 1013 is blocked by the first fluid control surface 1210 of the main fixed valve plate 121; when the regeneration control valve 30 is in the water replenishment working position, the ninth channel 109 and the first jet channel 1011 are respectively blocked by the fourth fluid control surface 3220 of the regeneration moving valve plate 322, and the water inlet channel 1014 is blocked by the third fluid control surface 3210 of the regeneration fixed valve plate 321. It can be understood that when the main control valve 10 is in the softening working position and the regeneration control valve 30 is in the water replenishment working position, the water softener of this invention can provide softened water to the user while simultaneously replenishing the softened water supply. In other words, when the main control valve 10 is in the softening working position and the regeneration control valve 30 is in the water replenishment working position, softened water can flow through the second softening flow channel 10012 and the third softening flow channel 10013 formed by the main control valve 10 of this utility model water softener to the outlet 1104, providing softened water to the user. In existing water softeners, the regeneration of the softening material and the replenishment of water to the brine tank are continuous. First, the brine in the brine tank is used to regenerate the softening material, then water is replenished to the brine tank (the brine formed by the replenished water is for the next regeneration), and then the control valve of the water softener is switched to the softening working position (the water supply time in the softening working position is often relatively long, such as 1-2 weeks). The existing regeneration and replenishment control process of current water softeners prevents them from being controlled by first switching to the replenishment position, then to the regeneration position, and finally to the softening position. This is because the regeneration process of the softening material takes at least two hours, typically starting at 2 AM and ending at 4 AM to avoid disrupting user access. The salt in the brine tank takes approximately six hours to dissolve. If water is replenished first, followed by regeneration of the softening material, the brine tank would need to be replenished around 8 PM (8 PM). Switching the control valve position in existing single-valve water softeners would interrupt the softened water supply. Furthermore, during the replenishment period, even with a continuous water supply valve, the water supplied is mostly raw water. Additionally, 8 PM is peak water usage time. The interruption of softened water supply or the inability to continuously provide softened water during replenishment in existing water softeners causes significant inconvenience to users. Secondly, the existing regeneration and replenishment control of water softeners can lead to prolonged exposure to salt solution in the brine tank (the regeneration cycle of the softening material in a water softener is 1-2 weeks), which can easily cause salt bridges and hinder salt dissolution. Finally, most brine tanks are manufactured using a blow molding process, making them prone to damage under prolonged brine pressure.However, in this utility model water softener, the regeneration control valve 30's water replenishment position and the main control valve 10's softening position are each controlled independently by their respective planar valves. When the main control valve 10 is in the softening position and the regeneration control valve 30 is in the water replenishment position, this utility model water softener can provide softened water to the user while replenishing water to the brine tank. This allows the water softener to replenish soft water to the brine tank several hours before regeneration, and still provide softened water to the user while replenishing the brine tank. In this way, after water replenishment, the regeneration control valve 30 can return from the water replenishment position to the stop-flow position to wait for the salt to dissolve. This not only allows for water replenishment during the user's daily water usage time and a continuous supply of softened water, but also prevents the long-term presence of brine in the brine tank, preventing salt bridge formation and damage to the brine tank due to brine pressure. Furthermore, since the water replenishment position of the regeneration control valve 30 and the softening position of the main control valve 10 of the water softener of this utility model are controlled separately by their respective planar valves, the supply of softened water is uninterrupted when the regeneration control valve 30 switches from the stop-flow position to the water replenishment position. Because the dissolution of salt in the salt tank takes about 6 hours, after the water replenishment is completed, the regeneration control valve 30 switches from the water replenishment position to the stop-flow position again (the supply of softened water is uninterrupted during the switching). After continuing to supply softened water for about 6 hours (waiting for the salt to dissolve), the water softener of this utility model enters the backwashing working state and the regeneration working state for regeneration under the switching and mutual cooperation of the respective working positions of the main control valve 10 and the regeneration control valve 30.

[0138] As shown in the attached image. Figure 16K , Figure 16L , Figure 22 and Figure 23F As shown in the figure, in this embodiment of the water softener, the active valve plate 122 of the main control valve 10 can rotate relative to the main stationary valve plate 121, thereby giving the main control valve 10 a forward washing working position. When the main control valve 10 is in the forward washing working position, the sixth channel 106 of the main control valve 10 is connected to the first channel 101, thereby forming a first forward washing flow channel 10051 that is connected to the water inlet 1106 and the first opening 1101 of the main valve body 11, respectively. The sewage discharge channel 1013 is connected to the third channel 103, thereby forming a second forward washing flow channel 10052 that is connected to the second opening 1102 and the sewage discharge opening 1113 of the main valve body 11, respectively. Figure 16K , Figure 16L and Figure 23FAs shown, when the main control valve 10 is in the positive washing position, the seventh channel 107 is connected to the second channel 102, the eighth channel 108 is connected to the fifth channel 105, and the fourth channel 104 is blocked by the second fluid control surface 1220 of the active valve plate 122; when the regeneration control valve 30 is in the stop-flow position, the ninth channel 109, the tenth channel 1010 and the first jet channel 1011 are blocked by the fourth fluid control surface 3220 of the regeneration active valve plate 322, the water inlet channel 1014 is blocked by the third fluid control surface 3210 of the regeneration stationary valve plate 321, and the conduction channel 1015 is connected to the second jet channel 1012. Although the seventh channel 107 is connected to the second channel 102, the eighth channel 108 is connected to the fifth channel 105, and the guiding channel 1015 is connected to the second jet channel 1012, a flow path that allows water to flow through cannot be formed. It can be understood that when the main control valve 10 is in the forward washing position and the regeneration control valve 30 is in the stop-flow position, although the eighth channel 108 is connected to the fifth channel 105, the fifth channel 105 is blocked by the active valve plate 122 because the eighth channel 108 is a blind orifice. Furthermore, because the fourth channel 104 is blocked by the second fluid control surface 1220 of the active valve plate 122, the fourth channel 104 and the fifth channel 105 are respectively connected to the outlet 1104, thus preventing untreated water from flowing out of the outlet 1104.

[0139] In summary, the control valve assembly 1 of the water softener according to this embodiment of the present invention can not only control the water softener to generate a larger flow of softened water in the softening working state, but also prevent the outlet 1104 from supplying raw water in the counter-current regeneration working state, co-current regeneration working state, backwashing working state, softened water replenishment working state, and forward washing working state. This makes the control valve assembly 1 of the water softener according to this embodiment of the present invention suitable for use in industrial water treatment, because in industrial water treatment, the outlet 1104 cannot supply raw water in the rinsing, regeneration, and replenishment working states other than the softening working state, as untreated raw water can easily affect subsequent water treatment equipment. Particularly noteworthy is that the control valve assembly 1 of the water softener according to this embodiment of the present invention achieves the above functions without changing any structure of the existing dual-opening softening device, and further enables the supply of softened water while replenishing softened water to the brine tank.Since planar valves are designed according to the principle of equal division, one of the main tasks in designing planar valves is to avoid unnecessary interference between the channels of the active valve plate and the main stationary valve plate. In other words, during the design process, not only must the function of the predetermined working position be achieved, but also, in order to generate a larger flow rate of softened water, the number of equal divisions of the inflow channel of the active valve plate, the number of blind holes in the active valve plate, the number of equal divisions of the inflow channel of the main stationary valve plate, and the number of outflow channels of the main stationary valve plate must be increased. However, it is also necessary to simultaneously avoid interference between the channels of the active and main stationary valve plates. It is understandable that when the number of equal divisions of the main stationary valve plate and the active valve plate is fixed... In this situation, increasing the number of water passages and avoiding interference between passages are contradictory. One of the design objectives of a planar valve is to resolve this contradiction. In this embodiment of the water softener, the inflow passage of the active valve plate 122 of the main control valve 10 occupies two equal parts (the sixth passage 106). Simultaneously, the active valve plate 122 has two blind holes (the seventh passage 107 and the eighth passage 108), which is one more equal-part inflow passage and one more blind hole than the moving valve plate of a typical water softener's planar valve. Furthermore, the first passage 101, which serves as the inflow passage of the main stationary valve plate 121 of the main control valve 10, occupies two equal parts. The main control valve 10 has two pairs of outlet channels (the second channel 102 and the fourth channel 104, the third channel 103 and the fifth channel 105), which is one more equally divided actual inflow channel and one more pair of outlet channels than the fixed valve of a typical water softener's flat valve. Because the increased number of channels on the main fixed valve and the active valve can easily lead to interference between the more inflow channels and blind holes of the active valve and the more outlet channels of the main fixed valve, untreated water can flow out of the outlet 1104 in the counter-current sewage discharge position, the co-current sewage discharge position, the backwash position, or the forward wash position. This is especially problematic in any position other than the softening position. If untreated water flows out, the design of a planar valve for industrial water treatment is not feasible. However, the main control valve 10 of the water softener in this embodiment of the present invention is reasonably designed, especially the first channel 101, the second channel 102, the fourth channel 104, the third channel 103, the fifth channel 105, the sixth channel 106, the seventh channel 107, and the eighth channel 108. In the counter-current sewage discharge position, the co-current sewage discharge position, the backwash position, and the forward wash position, the fourth channel 104 and the fifth channel 105 are blocked by the active valve plate 122, so that the outlet 1104 does not provide untreated water.

[0140] It is worth noting that, as shown in the attached diagram... Figure 16A and Figure 23AAs shown, when the main control valve 10 of the water softener of this invention is in the softening working position, the generated softened water flows from the second channel 102 through the seventh channel 107 to the fourth channel 104, and from the third channel 103 through the eighth channel 108 to the fifth channel 105. In other words, when the main control valve 10 of the water softener of this invention is in the softening working position, the second channel 102, the seventh channel 107, and the fourth channel 104 of the main control valve 10 of the water softener of this invention form a flow channel for softened water to flow out (the second softening flow channel 10012), and the third channel 103, the eighth channel 108, and the fifth channel 105 form another flow channel for softened water to flow out (the third softening flow channel 10013). Those skilled in the art will recognize that the greatest challenge in designing planar valves for controlling multidirectional water flow, especially those for water softeners, lies in maximizing the utilization of the flow control surface and minimizing the impact of any blind orifices (if present) on the water flow rate, in order to maximize the flow rate while maintaining a fixed valve volume. (See attached figure.) Figures 7G to 7J As shown, unlike through holes (e.g., the sixth channel 106 of the main control valve 10 of the water softener of this invention), the cross-section (the cross-section of the portion disposed on the second fluid control surface 1220) and height (perpendicular to the second fluid control surface 1220) of the blind orifice both affect the effective orifice diameter. In particular, when the blind orifice is used for drainage, the water flow will impact the inner wall of the blind orifice before its flow direction changes and it is guided to a preset direction. (See attached figures.) Figures 7G to 7J , Figure 17B and Figure 17CAs shown, when the main control valve 10 of the water softener of this utility model is in the softening working position, a flow channel for softened water to flow out is formed through the second channel 102, the seventh channel 107 and the fourth channel 104 respectively, and another flow channel for softened water to flow out is formed through the third channel 103, the eighth channel 108 and the fifth channel 105. This not only increases the cross-section of the softened water to flow out (the second channel 102, the seventh channel 107, the fourth channel 104 and the third channel 103, the eighth channel 108 and the fifth channel 105), but also increases the height of the blind orifice perpendicular to the second fluid control surface 1220 (equivalent to doubling the height), thereby significantly increasing the water flow rate through the blind orifice. Therefore, the main control valve 10 of the water softener of this invention, when in the softening working position, forms a dual-channel softened water outlet channel. This not only improves the utilization rate of the first fluid control surface 1210 of the main fixed valve plate 121 and the second fluid control surface 1220 of the active valve plate 122 of the main control valve 10, but also solves the flow limitation imposed by the single blind orifice of the existing planar valves used in water softeners. Finally, the planar valves used in water softeners need to control multi-directional water flow and have at least five different functional positions (the water softener of this embodiment has six functional positions), making the structure too complex. Therefore, previously, those skilled in the art generally believed that it was impossible to design two different softened water flow channels. The main control valve 10 of this utility model water softener achieves six different functions while providing two different softened water outlet channels, overcoming the technical bias in the industry and solving the problems of low utilization rate and small water flow rate of existing planar valves used in water softeners.

[0141] As shown in the attached image. Figures 7A to 9BAs shown, according to an embodiment of the present invention, the main control valve 10 of the water softener has a first fluid control surface 1210 of the main fixed valve plate 121, which has a central portion 12101 and an edge portion 12102 as shown by the dotted lines in the figure. The central portion 12101 and the edge portion 12102 are located at the top end 1214 of the main fixed valve plate 121. The edge portion 12102 (or the portion other than the central portion 12101) of the first fluid control surface 1210 is equally divided into a first portion 1201, a second portion 1202, a third portion 1203, a fourth portion 1204, a fifth portion 1205, a sixth portion 1206, a seventh portion 1207, an eighth portion 1208, a ninth portion 1209, a tenth portion 12010, and an eleventh portion 12011 as shown by the dotted lines. The second fluid control surface 1220 of the active valve plate 122 of the control valve 10 has a central region 12201 (shown by a dashed line in the figure) and an edge region 12202 extending outward from the central region 12201. The central region 12201 and the edge region 12202 are located at the bottom end 1221 of the active valve plate 122.

[0142] As shown in the attached image. Figures 12A to 14BAs shown, the third fluid control surface 3210 of the regeneration control valve 30 of the water softener according to this embodiment of the present invention has a regeneration center portion 32101 and a regeneration edge portion 32102 as shown by the dotted lines in the figure. The regeneration center portion 32101 and the regeneration edge portion 32102 are provided at the regeneration top end portion 3214 of the regeneration control valve 3211, and the regeneration edge portion 32102 (or the portion other than the regeneration center portion 32101) of the third fluid control surface 3210 is equally divided into a first regeneration portion 3201, a second regeneration portion 3202, and a third regeneration portion 3203 as shown by the dotted lines. The regeneration control valve 30 comprises a fourth regeneration section 3204, a fifth regeneration section 3205, a sixth regeneration section 3206, and a seventh regeneration section 3207. The fourth fluid control surface 3220 of the regeneration control valve 30 has a regeneration center region 32201 (shown by a dashed line in the figure) and a regeneration edge region 32202 extending outward from the regeneration center region 32201. The regeneration center region 32201 and the regeneration edge region 32202 are located at the regeneration bottom end 3221 of the regeneration control valve 3222. The regeneration edge region 32202 (of the regeneration center region 3205) of the fourth fluid control surface 3220 is also located at the regeneration bottom end 3221 of the regeneration control valve 3222. The portion excluding 2201 is equally divided into a first regeneration region 3001, a second regeneration region 3002, a third regeneration region 3003, a fourth regeneration region 3004, a fifth regeneration region 3005, a sixth regeneration region 3006, and a seventh regeneration region 3007, as indicated by dashed lines; wherein the ninth channel 109 extends downward from the first regeneration portion 3201 of the third fluid control surface 3210 of the regeneration fixed valve plate 321, and the first jet channel 1011 extends downward from the third regeneration portion 3203 and the fourth regeneration portion 3204 of the third fluid control surface 3210 of the regeneration fixed valve plate 321. The tenth channel 1010 extends downward from the sixth regeneration portion 3206 and the seventh regeneration portion 3207 of the third fluid control surface 3210 of the regeneration fixed valve plate 321; the second jet channel 1012 extends downward from the regeneration center portion 32101 of the third fluid control surface 3210 of the regeneration fixed valve plate 321; the water inlet channel 1014 extends upward from the first regeneration region 3001 of the fourth fluid control surface 3220 of the regeneration moving valve plate 322; and the guiding channel 1015 extends upward from the fifth regeneration region 3005 and the regeneration center region 32201 of the fourth fluid control surface 3220 of the regeneration moving valve plate 322.

[0143] Therefore, the arrangement of the first channel 101, the fifth channel 105, the third channel 103, the second channel 102, and the fourth channel 104 of the main control valve 10 of the water softener according to this embodiment of the present invention on the first fluid control surface 1210, and the arrangement of the sixth channel 106, the eighth channel 108, the sewage discharge channel 1013, and the seventh channel 107 of the main control valve 10 on the second fluid control surface 1220 of the active valve plate 122, determines that when the water softener according to this embodiment of the present invention... The first channel 101 of the main control valve 10 of the water softener is distributed at two equally divided positions on the first fluid control surface 1210 (two of the eleven divisions of the first fluid control surface 1210). The second channel 102 and the fourth channel 104 of the main control valve 10 are each distributed at one equally divided position on the first fluid control surface 1210. The third channel 103 and the fifth channel 105 of the main control valve 10 are each distributed at one equally divided position on the first fluid control surface 1210. The sixth channel 104 of the main control valve 10... Channel 106 is distributed at two equally divided positions on the second fluid control surface 1220 (two of the eleven divisions of the second fluid control surface 1220). The seventh channel 107 of the main control valve 10 is distributed at two equally divided positions on the second fluid control surface 1220. The eighth channel 108 of the main control valve 10 is distributed at two equally divided positions on the second fluid control surface 1220. This allows the sixth channel 106, the eighth channel 108, the drain channel 1013, and the seventh channel 107 of the main control valve 10 to be connected. The main control valve 10 selectively connects to the first channel 101, the fifth channel 105, the third channel 103, the second channel 102, and the fourth channel 104 at different working positions. When the water softener of this utility model softens the raw water, most of the area of ​​the first fluid control surface 1210 of the main control valve 10 of this utility model (excluding the intervals between the channels distributed on the first fluid control surface 1210 and the central part 12101 that does not participate in the conduction, approximately 6 / 11 of the area) participates in the water flow. Since the raw water channel for supplying raw water to the softening device 20 of the water softener of this utility model is composed of the first channel 101 and the sixth channel 106, wherein the first channel 101 occupies two equal parts of the first fluid control surface 1210 (approximately 2 / 11 of the total area of ​​the first fluid control surface 1210), and the sixth channel 106 occupies two equal parts of the second fluid control surface 1220 (approximately 2 / 11 of the total area of ​​the second fluid control surface 1220), it is significantly higher than the proportion of the total area of ​​the first fluid control surface and the second fluid control surface of the planar valve used for supplying raw water in the existing planar valve for water softeners.Correspondingly, the water outlet channels (the second channel 102 and the third channel 103) connected to the softening device 20 also occupy two equal parts of the first fluid control surface 1210 (approximately 2 / 11 of the total area of ​​the first fluid control surface 1210), and the soft water supply channels (the fourth channel 104 and the fifth channel 105) connected to the water outlet 1104 also occupy two equal parts of the first fluid control surface 1210 (approximately 2 / 11 of the total area of ​​the first fluid control surface 1210). At this time, the active valve plate 122 needs to have… The seventh channel 107, which communicates with the second channel 102 and the fourth channel 104, and the eighth channel 108, which communicates with the third channel 103 and the fifth channel 105, are required to achieve the dual-channel water supply function. The seventh channel 107 also occupies two equal parts of the second fluid control surface 1220 (approximately 2 / 11 of the total area of ​​the second fluid control surface 1220), and the eighth channel 108 also occupies two equal parts of the second fluid control surface 1220 (approximately 2 / 11 of the total area of ​​the second fluid control surface 1220). Therefore, most of the area (approximately 6 / 11 of the area) of the first fluid control surface 1210 and most of the area (approximately 6 / 11 of the area) of the second fluid control surface 1220 of the main control valve 10 of this utility model water softener participates in the water flow. In this utility model water softener, the proportion of the total cross-sectional area of ​​the inflow channel supplying raw water to the softening device of the main control valve 10 and the total cross-sectional area of ​​the outflow channel of the softened water to the total area of ​​the flow control surfaces of the fixed valve plate and the moving valve plate can be increased, thereby significantly improving the softening water treatment speed and softened water flow rate of the water softener. In other words, the arrangement of the first channel 101, the fifth channel 105, the third channel 103, the second channel 102, and the fourth channel 104 of the main control valve 10 on the first fluid control surface 1210, and the arrangement of the sixth channel 106, the eighth channel 108, the sewage discharge channel 1013, and the seventh channel 107 of the main control valve 10 on the second fluid control surface 1220 of the active valve plate 122, can significantly improve the softening water treatment speed and softened water flow rate of the water softener. The equal division of the first fluid control surface 1210 occupied by the first channel 101, the fifth channel 105, the third channel 103, the second channel 102, and the fourth channel 104 of the control valve 10, and the equal division of the second fluid control surface 1220 of the active valve plate 122 occupied by the sixth channel 106, the eighth channel 108, the drain channel 1013, and the seventh channel 107 of the main control valve 10, determine their selective connection mode in different working positions.

[0144] As shown in the attached image. Figures 7A to 9B and Figures 12A to 14BAs shown, exemplarily, the edge portion 12102 of the first fluid control surface 1210 of the main fixed valve plate 121 of the main control valve 10 is divided clockwise into the first portion 1201, the second portion 1202, the third portion 1203, the fourth portion 1204, the fifth portion 1205, the sixth portion 1206, the seventh portion 1207, the eighth portion 1208, the ninth portion 1209, the tenth portion 12010, and the eleventh portion 1201. 011, the edge region 12202 of the second fluid control surface 1220 of the active valve plate 122 of the main control valve 10 is divided clockwise into the first region 2001, the second region 2002, the third region 2003, the fourth region 2004, the fifth region 2005, the sixth region 2006, the seventh region 2007, the eighth region 2008, the ninth region 2009, the tenth region 20010, and the eleventh region 20011. In other words, the first fluid control surface 1210 of the main valve plate 121 of the main control valve 10 forms eleven equal divisions, and the second fluid control surface 1220 of the active valve plate 122 of the main control valve 10 forms eleven equal divisions. The regeneration edge portion 32102 of the third fluid control surface 3210 of the regeneration stationary valve plate 321 of the regeneration control valve 30 is divided clockwise into the first regeneration portion 3201, the second regeneration portion 3202, the third regeneration portion 3203, the fourth regeneration portion 3204, the fifth regeneration portion 3205, the sixth regeneration portion 3206, and the seventh regeneration portion 3207. The regeneration edge region 32202 of the fourth fluid control surface 3220 of the regeneration moving valve plate 322 of the regeneration control valve 30 is divided clockwise into the first regeneration region 3001, the second regeneration region 3002, the third regeneration region 3003, the fourth regeneration region 3004, the fifth regeneration region 3005, the sixth regeneration region 3006, and the seventh regeneration region 3007. In other words, the third fluid control surface 3210 of the regeneration stationary valve plate 321 of the regeneration control valve 30 is divided into seven equal parts, and the fourth fluid control surface 3220 of the regeneration moving valve plate 322 of the regeneration control valve 30 is divided into seven equal parts. (See attached figures.) Figures 7A to 9B , Figure 16A and Figure 23AAs shown, when the active valve plate 122 of the main control valve 10 is rotated to the first and second divisions (the first region 2001 and the second region 2002) of the second fluid control surface 1220 of the active valve plate 122, respectively, being directly aligned with the first and second divisions (the first portion 1201 and the second portion 1202) of the first fluid control surface 1210 of the main stationary valve plate 121, the fifth and sixth divisions (the fifth region 2005 and the sixth region 2006) of the second fluid control surface 1220 of the active valve plate 122 of the main control valve 10 are directly aligned with the fifth and sixth divisions (the fifth portion 1205 and the sixth portion 1206) of the first fluid control surface 1210 of the main stationary valve plate 121, and the second fluid control surface 1220 of the active valve plate 122 of the main control valve 10... The seventh division (the seventh region 2007) is directly opposite the seventh division (the seventh part 1207) of the first fluid control surface 1210 of the main fixed valve plate 121. The ninth and tenth divisions (the ninth region 2009 and the tenth region 20010) of the second fluid control surface 1220 of the main control valve plate 122 are directly opposite the ninth and tenth divisions (the ninth part 1209 and the tenth part 12010) of the first fluid control surface 1210 of the main fixed valve plate 121, respectively. This causes the sixth channel 106 of the main control valve 10 to be connected to the first channel 101, the eighth channel 108 to be connected to the third channel 103 and the fifth channel 105, respectively, the drain channel 1013 to be blocked by the first fluid control surface 1210 of the main fixed valve plate 121, and the seventh channel 107 to be blocked by the first fluid control surface 1210 of the main fixed valve plate 121. It is connected to the second channel 102 and the fourth channel 104 respectively, and at this time the main control valve 10 is in the softening working position. As shown in the attached figure. Figures 12A to 14B , Figure 16B and Figure 23AAs shown, when the regeneration moving valve plate 322 of the regeneration control valve 30 is rotated to the point where the first regeneration region 3001 of the fourth fluid control surface 3220 of the regeneration moving valve plate 322 is directly opposite the fifth regeneration portion 3205 of the third fluid control surface 3210 of the regeneration stationary valve plate 321, the fifth regeneration region 3005 and the regeneration center region 32201 of the fourth fluid control surface 3220 of the regeneration moving valve plate 322 of the regeneration control valve 30 are directly opposite the second regeneration portion 3202 and the regeneration center region of the third fluid control surface 3210 of the regeneration stationary valve plate 321, respectively. 32101, thereby causing the water inlet channel 1014 of the regeneration control valve 30 to be blocked by the third fluid control surface 3210 of the regeneration fixed valve plate 321, the conduction channel 1015 to be connected to the second jet channel 1012, since the conduction channel 1015 is a blind hole, the second jet channel 1012 is blocked by the regeneration moving valve plate 322, the ninth channel 109, the tenth channel 1010 and the first jet channel 1011 are respectively blocked by the fourth fluid control surface 3220 of the regeneration moving valve plate 322, at this time the regeneration control valve 30 is in the stop working position. When the main control valve 10 is in the softening working position and the regeneration control valve 30 is in the flow-stopping working position, raw water is allowed to flow in from the inlet 1106 of the main valve body 11, through the sixth channel 106 and the first channel 101 to the first opening 1101, and further into the softening device 20 from the first connecting opening 201. The softened water, after being softened by the softening device 20, flows out from the second connecting opening 202 of the softening device 20 and further into the second opening 1102, flowing into the second opening 110. The water flow is divided into two streams flowing towards the outlet 1104. One stream flows sequentially through the second opening 1102, the fourth connecting channel 504, the third channel 103, the eighth channel 108, and the fifth channel 105 to the outlet 1104. The other stream flows sequentially through the second opening 1102, the fourth connecting channel 504, the second channel 102, the seventh channel 107, the fourth channel 104, and the fifth connecting channel 505 to the outlet 1104. The softened water flowing from the outlet 1104 is then further provided to the user. Accordingly, the water softener is in the softening operation state at this time.

[0145] As shown in the attached image. Figures 7A to 9B , Figure 16C and Figure 23BAs shown, when the active valve plate 122 of the main control valve 10 is rotated to the first and second divisions (the first region 2001 and the second region 2002) of the second fluid control surface 1220 of the active valve plate 122, respectively, being aligned with the seventh and eighth divisions (the seventh portion 1207 and the eighth portion 1208) of the first fluid control surface 1210 of the main stationary valve plate 121, the second fluid control surface of the active valve plate 122 of the main control valve 10... The fifth and sixth divisions (the fifth region 2005 and the sixth region 2006) of the main fixed valve plate 121 are respectively aligned with the eleventh and first divisions (the eleventh part 12011 and the first part 1201) of the first fluid control surface 1210 of the main fixed valve plate 121. The seventh division (the seventh region 2007) of the second fluid control surface 1220 of the main control valve plate 10 is aligned with the first fluid control surface of the main fixed valve plate 121. The second division (second portion 1202) of the second fluid control surface 1220 of the main control valve 10, the ninth and tenth divisions (ninth region 2009 and tenth region 20010) of the active valve plate 122 of the main control valve 10 are respectively aligned with the fourth and fifth divisions (fourth portion 1204 and fifth portion 1205) of the first fluid control surface 1210 of the main stationary valve plate 121, thereby causing the sixth channel 1 of the main control valve 10 to... 06 is blocked by the first fluid control surface 1210 of the main valve plate 121. The eighth channel 108 is connected to the first channel 101, the sewage discharge channel 1013 is connected to the first channel 101, the seventh channel 107 is connected to the fifth channel 105, and the second channel 102, third channel 103, and fourth channel 104 are blocked by the second fluid control surface 1220 of the active valve plate 122. At this time, the main control valve 10 is in the reverse flow sewage discharge working position. As shown in the attached figure. Figures 12A to 14B , Figure 16D and Figure 23BAs shown, when the regeneration moving valve plate 322 of the regeneration control valve 30 is rotated to the point where the first regeneration region 3001 of the fourth fluid control surface 3220 of the regeneration moving valve plate 322 is directly opposite the third regeneration portion 3203 of the third fluid control surface 3210 of the regeneration stationary valve plate 321, the fifth regeneration region 3005 and the regeneration center region 32201 of the fourth fluid control surface 3220 of the regeneration moving valve plate 322 of the regeneration control valve 30 are directly opposite the regeneration stationary valve plate 321.

The conduction channel 1015 is connected to the second jet channel 1012 and the tenth channel 1010 respectively. The ninth channel 109 is blocked by the fourth fluid control surface 3220 of the regeneration moving valve plate 322. At this time, the regeneration control valve 30 is in the countercurrent regeneration working position. When the main control valve 10 is in the counter-current sewage discharge position and the regeneration control valve 30 is in the counter-current regeneration position, raw water is allowed to flow in from the inlet 1106 of the main valve body 11, through the valve chamber 110, the first conductive opening 3101, the first connecting channel 501, the regeneration valve chamber 310, and the inlet channel 1014 into the first jet channel 1011, flowing to the first jet opening 1111 of the regeneration valve body 31, and then into the jet outlet 182 of the ejector 18. After being jetted by the ejector 18, it mixes with the brine (such as sodium chloride solution) from the brine suction port 181 to form a regeneration solution. The regeneration solution flows into the regeneration valve body 31 through the jet inlet 183 of the ejector 18. The second jet opening 1112 of the main valve body 11 then flows through the second jet channel 1012, the guiding channel 1015, the tenth channel 1010, the third connecting channel 503, the third guiding opening 3103, the fourth connecting channel 504, and the second opening 1102 into the second connecting opening 202 of the softening device 20, and then into the softening device 20, regenerating the water treatment material or mechanism of the softening device 20, such as softening resin. The wastewater generated after regeneration flows out from the first connecting opening 201 of the softening device 20, and then sequentially through the first opening 1101, the first channel 101, the sewage channel 1013, and the sewage opening 1113 of the main valve body 11. Accordingly, the water softener is in the countercurrent regeneration working state at this time.

[0146] As shown in the attached image. Figures 7A to 9B , Figure 16E and Figure 23CAs shown, when the active valve plate 122 of the main control valve 10 is rotated to the first and second divisions (the first region 2001 and the second region 2002) of the second fluid control surface 1220 of the active valve plate 122, respectively, being aligned with the third and fourth divisions (the third portion 1203 and the fourth portion 1204) of the first fluid control surface 1210 of the main stationary valve plate 121, the second fluid of the active valve plate 122 of the main control valve 10... The fifth and sixth divisions (the fifth region 2005 and the sixth region 2006) of the control surface 1220 are respectively aligned with the seventh and eighth divisions (the seventh part 1207 and the eighth part 1208) of the first fluid control surface 1210 of the main fixed valve plate 121. The seventh division (the seventh region 2007) of the second fluid control surface 1220 of the active valve plate 122 of the main control valve 10 is aligned with the first fluid control surface of the main fixed valve plate 121.

The sewage discharge channel 1013 is connected to the second channel 102, the seventh channel 107 is connected to the first channel 101, and the third channel 103, the fourth channel 104, and the fifth channel 105 are respectively blocked by the second fluid control surface 1220 of the active valve plate 122. At this time, the main control valve 10 is in the downstream sewage discharge working position. As shown in the attached figure. Figures 12A to 14B , Figure 16F and Figure 23CAs shown, when the regeneration moving valve plate 322 of the regeneration control valve 30 is rotated to the point where the first regeneration region 3001 of the fourth fluid control surface 3220 of the regeneration moving valve plate 322 is directly opposite the fourth regeneration portion 3204 of the third fluid control surface 3210 of the regeneration stationary valve plate 321, the fifth regeneration region 3005 and the regeneration center region 32201 of the fourth fluid control surface 3220 of the regeneration moving valve plate 322 of the regeneration control valve 30 are directly opposite the first regeneration portion 3201 and the regeneration center portion 32101 of the third fluid control surface 3210 of the regeneration stationary valve plate 321, respectively. This causes the water inlet channel 1014 of the regeneration control valve 30 to connect with the first jet channel 1011, and the connecting channel 1015... The tenth channel 1010 is connected to the second jet channel 1012 and the ninth channel 109 respectively. The tenth channel 1010 is blocked by the fourth fluid control surface 3220 of the regeneration valve plate 322. At this time, the regeneration control valve 30 is in the downstream regeneration working position. When the main control valve 10 is in the downstream sewage discharge position and the regeneration control valve 30 is in the downstream regeneration position, raw water is allowed to flow in from the inlet 1106 of the main valve body 11, through the valve chamber 110, the first conductive opening 3101, the first connecting channel 501, the regeneration valve chamber 310, and the inlet channel 1014 into the first jet channel 1011, flowing to the first jet opening 1111 of the regeneration valve body 31, and then into the jet outlet 182 of the ejector 18. After being jetted by the ejector 18, it mixes with the brine (such as sodium chloride solution) from the brine suction port 181 to form a regeneration solution. The regeneration solution flows into the first jet opening 1111 of the regeneration valve body 31 through the jet inlet 183 of the ejector 18. The water flows through the second jet opening 1112, then through the second jet channel 1012, the guiding channel 1015, the ninth channel 109, the second connecting channel 502, the second guiding opening 3102, the first channel 101, and the first opening 1101 into the first connecting opening 201 of the softening device 20, and then into the softening device 20, regenerating the water treatment material or mechanism of the softening device 20, such as softening resin. The wastewater generated after regeneration flows out from the second connecting opening 202 of the softening device 20, and then sequentially through the second opening 1102, the fourth connecting channel 504, the second channel 102, the sewage discharge channel 1013, and the sewage discharge opening 1113 of the main valve body 11. Accordingly, the water softener is in the downstream regeneration working state at this time.

[0147] As shown in the attached image. Figures 7A to 9B , Figure 16G , Figure 16H and Figure 23DAs shown, when the active valve plate 122 of the main control valve 10 is rotated to the first and second divisions (the first region 2001 and the second region 2002) of the second fluid control surface 1220 of the active valve plate 122, which are respectively aligned with the sixth and seventh divisions (the sixth portion 1206 and the seventh portion 1207) of the first fluid control surface 1210 of the main fixed valve plate 121, the second fluid of the active valve plate 122 of the main control valve 10... The fifth and sixth divisions (the fifth region 2005 and the sixth region 2006) of the control surface 1220 are respectively aligned with the tenth and eleventh divisions (the tenth part 12010 and the eleventh part 12011) of the first fluid control surface 1210 of the main fixed valve plate 121. The seventh division (the seventh region 2007) of the second fluid control surface 1220 of the active valve plate 122 of the main control valve 10 is aligned with the main fixed valve plate 121. The first division (first portion 1201) of the first fluid control surface 1210, and the ninth and tenth divisions (ninth region 2009 and tenth region 20010) of the second fluid control surface 1220 of the main control valve 10 are respectively aligned with the third and fourth divisions (third portion 1203 and fourth portion 1204) of the first fluid control surface 1210 of the main control valve 10, thereby enabling the main control... The sixth channel 106 of valve 10 is connected to the third channel 103, the eighth channel 108 is connected to the fourth channel 104, the sewage channel 1013 is connected to the first channel 101, the seventh channel 107 is blocked by the first fluid control surface 1210 of the main fixed valve plate 121, and the second channel 102 and the fifth channel 105 are blocked by the second fluid control surface 1220 of the active valve plate 122. At this time, the main control valve 10 is in the backwash working position. When the main control valve 10 is in the backwash position and the regeneration control valve 30 is in the stop-flow position, raw water is allowed to flow in from the inlet 1106 of the main valve body 11, through the sixth channel 106 into the third channel 103, and through the fourth connecting channel 504 to the second opening 1102. Then, through the second opening 1102, it flows to the second connecting opening 202 of the softening device 20 to backwash the softening material of the softening device 20. The resulting wastewater further flows out through the first connecting opening 201 and into the first opening 1101, and then is discharged through the first channel 101, the drain channel 1013, and the drain opening 1113. Accordingly, the water softener is in the backwash working state at this time.

[0148] As shown in the attached image. Figures 12A to 14B , Figure 16I , Figure 16J and Figure 23EAs shown, when the regeneration moving valve plate 322 of the regeneration control valve 30 is rotated to the point where the first regeneration region 3001 of the fourth fluid control surface 3220 of the regeneration moving valve plate 322 is directly opposite the second regeneration portion 3202 of the third fluid control surface 3210 of the regeneration stationary valve plate 321, the fifth regeneration region 3005 and the regeneration center region 32201 of the fourth fluid control surface 3220 of the regeneration moving valve plate 322 of the regeneration control valve 30 are directly opposite the sixth regeneration portion 3206 and the regeneration center portion 32101 of the third fluid control surface 3210 of the regeneration stationary valve plate 321, respectively. This causes the water inlet channel 1014 of the regeneration control valve 30 to be blocked by the third fluid control surface 3210 of the regeneration stationary valve plate 321, and the conduction channel 1015... The tenth channel 1010 and the second jet channel 1012 are respectively connected. The ninth channel 109 and the first jet channel 1011 are respectively blocked by the fourth fluid control surface 3220 of the regenerative valve plate 322. At this time, the regenerative control valve 30 is in the water replenishment working position. When the main control valve 10 is in the softening working position and the regeneration control valve 30 is in the water replenishment working position, raw water is allowed to flow in from the inlet 1106 of the main valve body 11, flow into the first channel 101 through the sixth channel 106, flow to the first opening 1101 of the main valve body 11, and then flow through the first opening 1101 to the first connecting opening 201 of the softening device 20, so that it is softened to obtain softened water. The obtained softened water further flows out and into the second opening 1102 of the main valve body 11 through the second connecting opening 202. The water flowing into the second opening 1102 is divided into three paths. The first path flows sequentially through the second opening 1102, the fourth connecting channel 504, the third conducting opening 3103, and the third connecting channel 302. The water flows through the ten channels 1010, the guiding channel 1015, and the second jet channel 1012 to the second jet opening 1112, and then sequentially through the jet inlet 183, the brine inlet 181, and the brine suction pipe 184 of the jet injector 18 into the brine tank 185 for replenishment. A second path flows sequentially through the second opening 1102, the fourth connecting channel 504, the third channel 103, the eighth channel 108, and the fifth channel 105 to the outlet 1104. A third path flows sequentially through the second opening 1102, the fourth connecting channel 504, the second channel 102, the seventh channel 107, the fourth channel 104, and the fifth connecting channel 505 to the outlet 1104. The softened water flowing from the outlet 1104 is further provided to the user. Accordingly, the water softener is in the softened water replenishment state at this time, simultaneously supplying softened water.

[0149] As shown in the attached image. Figures 7A to 9B , Figure 16K , Figure 16L and Figure 23FAs shown, when the active valve plate 122 of the main control valve 10 is rotated to the first and second divisions (the first region 2001 and the second region 2002) of the second fluid control surface 1220 of the active valve plate 122, respectively, being aligned with the eleventh and first divisions (the eleventh part 12011 and the first part 1201) of the first fluid control surface 1210 of the main stationary valve plate 121, the active valve plate 10... The fifth and sixth divisions (the fifth region 2005 and the sixth region 2006) of the second fluid control surface 1220 of the valve disc 122 are respectively aligned with the fourth and fifth divisions (the fourth portion 1204 and the fifth portion 1205) of the first fluid control surface 1210 of the main valve disc 121. The seventh division (the seventh region 2006) of the second fluid control surface 1220 of the active valve disc 122 of the main control valve 10 is also aligned with the seventh division (the seventh region 2006). 07) The sixth division (sixth part 1206) of the first fluid control surface 1210 of the main fixed valve plate 121, the ninth and tenth divisions (ninth region 2009 and tenth region 20010) of the second fluid control surface 1220 of the main control valve plate 122 are respectively aligned with the eighth and ninth divisions (eighth part 1208 and ninth part 1209) of the first fluid control surface 1210 of the main fixed valve plate 121, thereby connecting the sixth channel 106 with the first channel 101, the eighth channel 108 with the fifth channel 105, the sewage channel 1013 with the third channel 103, the seventh channel 107 with the second channel 102, and the fourth channel 104 is blocked by the second fluid control surface 1220 of the active valve plate 122. At this time, the main control valve 10 is in the positive washing working position. When the main control valve 10 is in the forward flushing position and the regeneration control valve 30 is in the stop-flow position, raw water is allowed to flow in from the inlet 1106 of the main valve body 11, through the sixth channel 106 into the first channel 101, to the first opening 1101 of the main valve body 11, and then through the first opening 1101 to the first connecting opening 201 of the softening device 20, so as to perform forward flushing of the softening material of the softening device 20. The resulting wastewater further flows out through the second connecting opening 202 and through the second opening 1102, the fourth connecting channel 504, the third channel 103 and the sewage discharge channel 1013 to the sewage discharge opening 1113. Accordingly, the water softener is in the forward flushing state at this time.

[0150] It is understood that when the second fluid control surface 1220 of the active valve plate 122 is disposed on the first fluid control surface 1210 of the main fixed valve plate 121, the central region 12201 of the second fluid control surface 1220 of the active valve plate 122 is directly opposite the central portion 12101 of the first fluid control surface 1210 of the main fixed valve plate 121, and the edge region 12202 of the second fluid control surface 1220 of the active valve plate 122 is directly opposite the edge portion 12102 of the first fluid control surface 1210 of the main fixed valve plate 121. Optionally, the first fluid control surface 1210 of the main stationary valve plate 121 and the second fluid control surface 1220 of the active valve plate 122 of the main control valve 10 are both circular. The first channel 101, the fifth channel 105, the third channel 103, the second channel 102 and the fourth channel 104 of the main control valve 10 are all radially disposed on the first fluid control surface 1210 of the main stationary valve plate 121, and the sixth channel 106, the eighth channel 108, the drain channel 1013 and the seventh channel 107 of the main control valve 10 are all radially disposed on the second fluid control surface 1220 of the active valve plate 122. Preferably, the first channel 101 of the main control valve 10 extends downward and outward from the first fluid control surface 1210 of the main fixed valve plate 121, the fifth channel 105 extends downward and outward from the first fluid control surface 1210 of the main fixed valve plate 121, the third channel 103 extends downward and inward from the first fluid control surface 1210 of the main fixed valve plate 121, the second channel 102 extends downward and inward from the first fluid control surface 1210 of the main fixed valve plate 121, and the fourth channel 104 extends downward and inward from the first fluid control surface 1210 of the main fixed valve plate 121. Optionally, the edge portion 12102 of the first fluid control surface 1210 is divided counterclockwise into the first portion 1201, the second portion 1202, the third portion 1203, the fourth portion 1204, the fifth portion 1205, the sixth portion 1206, the seventh portion 1207, the eighth portion 1208, the ninth portion 1209, the tenth portion 12010, and the eleventh portion 12011, and the main control valve 10 The edge region 12202 of the second fluid control surface 1220 of the active valve plate 122 is divided counterclockwise into the first region 2001, the second region 2002, the third region 2003, the fourth region 2004, the fifth region 2005, the sixth region 2006, the seventh region 2007, the eighth region 2008, the ninth region 2009, the tenth region 20010, and the eleventh region 20011.

[0151] As shown in the attached image. Figures 6A to 6LAs shown, the main valve body 11 of the main control valve 10 has an inner wall 111, wherein the main fixed valve plate 121 is adapted to be disposed in the valve cavity 110 with the first fluid control surface 1210 facing upward, and the active valve plate 122 is adapted to be disposed in the valve cavity 110 with the second fluid control surface 1220 facing downward, wherein the valve cavity 110 is always connected to the sixth channel 106. It is worth noting that the main fixed valve plate 121 of the main control valve 10 can be detachably disposed in the inner wall 111 of the main valve body 11, or it can be integrally formed with the inner wall 111 of the main valve body 11 of the main control valve 10. Those skilled in the art will understand that when the main fixed valve plate 121 is detachably disposed in the main valve body 11, the main fixed valve plate 121 and the main valve body 11 are kept synchronized by a fixing mechanism. For example, as shown in the attached figures... Figures 6A to 6L As shown, the main valve plate 121 has a braking element 123 protruding outward from its edge, and the inner wall 111 of the main valve body 11 has a braking portion 1110. The braking element 123 of the main valve plate 121 is configured to engage with the braking portion 1110 of the inner wall 111 of the main valve body 11 to ensure synchronization (or prevent relative rotation) between the main valve plate 121 and the main valve body 11, and to ensure that the various channels of the main valve plate 121 communicate with the corresponding openings of the main valve body 11. It can be understood that when the main valve plate 121 is detachably disposed within the main valve body 11, it can be manufactured separately. In other words, in this case, the main valve plate 121 can be made of a wear-resistant material, thereby improving the service life of the main valve plate 121 (or the entire main control valve 10).
