[0002] With the development of economy and the progress of society, people have higher and higher requirements for the quality of life, and various water treatment equipment are used in people's lives. Common water treatment equipment includes water softeners and water purifiers. Among them, water softeners are widely used in people's lives because they can remove calcium and magnesium ions in water and reduce the hardness of water.

[0003] The water softener includes a resin tank. The functional ions (sodium ions) on the resin in the resin tank are exchanged with the calcium and magnesium ions in the water, thereby absorbing the excess calcium and magnesium ions in the water to achieve the purpose of removing scale (calcium carbonate or magnesium carbonate).

[0004] Generally, a water softener has soft water supply state, forward washing state, backwash state, regeneration state and salt supply device water replenishment state. In the soft water supply state, the water softener can supply softened soft water, but in the forward washing state, backwash state, regeneration state and salt supply device water replenishment state, the water softener cannot supply soft water normally, resulting in flow interruption, that is, in the above-mentioned multiple states, water (including raw water and soft water) can no longer flow from the water softener to the user, resulting in flow interruption, which brings a bad user experience.

[0078] See also Figure 1 One embodiment of the present application provides a water softener, which includes a water softening device 100 and a regeneration device 600 that are interconnected. The water softening device 100 contains functional ions (sodium ions), which can exchange with calcium and magnesium ions in raw water, and absorb excess calcium and magnesium ions in raw water to turn hard water into soft water. Usually, during the sodium ion exchange process, when hardness appears in the soft water and the residual hardness exceeds the water quality standard, it is considered that the sodium ions have failed. The regeneration device 600 can pass brine (sodium chloride solution) into the water softening device 100, and the brine passes through the failed resin to replace the calcium and magnesium ions therein into the solution, thereby completing the regeneration of the sodium ions in the resin and restoring the soft water function of the water softening device 100.

[0079] The water softener has a soft water supply state and a non-soft water supply state, and the water softener can switch between the soft water supply state and the non-soft water supply state.

[0080] In the soft water supply state, raw water flows into the water softener 100, and the functional ions (sodium ions) contained in the water softener 100 are exchanged with the calcium and magnesium ions in the raw water, and the excess calcium and magnesium ions in the water are adsorbed, so that the hard water becomes soft water and is discharged for use by the user. It should be noted here that when the water softener is in the soft water supply state, the water softener will not be able to supply raw water, and when it is not in the soft water supply state, the water softener can supply raw water to ensure that water flows out of the water softener in both the soft water supply state and the non-soft water supply state, so as to avoid the water softener being cut off and causing a bad experience to the user.

[0081] Specifically, the regeneration device 600 has a soft water supply channel and a raw water supply channel. When the water softener is in the soft water supply state, the soft water supply channel is connected, the raw water supply channel is cut off, and the water softener 100 is connected to the raw water source through the soft water supply channel, and the raw water flows into the water softener 100 through the soft water supply channel. The functional ions (sodium ions) contained in the water softener 100 are exchanged with the calcium and magnesium ions in the raw water, and the excess calcium and magnesium ions in the water are adsorbed, so that the hard water becomes soft water, and is discharged through the soft water supply channel for use by the user. Since the raw water supply channel is cut off, the water softener cannot supply raw water when supplying soft water.

[0082] When the water softener is in a non-soft water supply state, the soft water supply channel is cut off and the raw water supply channel is connected. When the water softener no longer supplies soft water, the water softener can supply raw water to ensure continuous flow of water, thereby improving user experience.

[0083] The water softener 100 includes a resin tank 200, an upper water distributor 300, a central tube 500 and a lower water distributor 400. The resin tank 200 includes a tank body and a resin containing functional ions disposed in the tank body. The upper ends of the upper water distributor 300 and the central tube 500 are both connected to the regeneration device 600, and the lower water distributor 400 is connected to the lower end of the central tube 500. When the water softener is in a soft water supply state, raw water first flows to the upper water distributor 300 through the soft water supply channel, and the upper water distributor 300 sprays water on the resin in the resin tank 200. The calcium and magnesium ions in the raw water are exchanged with the functional ions on the resin to form soft water, and then flow to the central tube 500 through the lower water distributor 400. The soft water flowing out of the central tube 500 flows out through the soft water supply channel on the regeneration device 600 for use by users.

[0084] In one embodiment, the non-soft water supply state includes a regeneration state. In the regeneration state, the regeneration device 600 can pass brine (sodium chloride solution) into the softening device 100. The brine passes through the failed resin to replace the calcium and magnesium ions therein into the solution, thereby completing the regeneration of the sodium ions in the resin and restoring the softening function of the softening device 100.

[0085] The regeneration state includes a first regeneration state and a second regeneration state. When the water softener is in the first regeneration state, the regeneration device 600 provides the water softener 100 with a first salt water having a first concentration, and the first salt water passes through the failed resin to replace the calcium and magnesium ions therein into the solution, thereby completing the regeneration of the sodium ions in the resin. In the second regeneration state, the regeneration device 600 provides the water softener 100 with a second salt water having a second concentration, and passes through the failed resin to replace the calcium and magnesium ions therein into the solution, thereby completing the regeneration of the sodium ions in the resin. The first concentration is not equal to the second concentration.

[0086] The water softener provided in the present application has different concentrations of the first salt water and the second salt water introduced into the water softening device 100 in the first regeneration state and the second regeneration state, that is, the water softener provided in the present application can sequentially introduce two salt waters of different concentrations into the water softening device 100. Compared with the setting in the prior art that the regeneration device 600 can only introduce one concentration of salt water into the water softening device 100, the combination of two salt waters of different concentrations can improve the regeneration rate of the functional ions of the water softener. When the regeneration rate is improved, the water output of the water softener can be increased accordingly.

[0087] When the water softener is in the first regeneration state and the second regeneration state, the first brine and the second brine provided by the regeneration device 600 first flow to the lower water distributor 400 through the central pipe 500, and are sprayed into the resin in the resin tank 200 through the lower water distributor 400. The brine passes through the failed resin to replace the calcium and magnesium ions therein into the solution. The replaced solution flows to the upper water distributor 300, and enters the regeneration device 600 from the upper water distributor 300 to be discharged.

[0088] The regeneration device 600 has a first regeneration channel and a second regeneration channel. When the water softener is in the first regeneration state, the first regeneration channel is connected to the central tube 500, and the first regeneration channel provides the first salt water to the water softener 100, and the second regeneration channel is cut off at this time. When the water softener is in the second regeneration state, the second regeneration channel is connected to the central tube 500, and the second regeneration channel provides the second salt water to the water softener 100, and the first regeneration channel is cut off at this time. It should be understood that in other embodiments, the regeneration device 600 can also be provided with only one regeneration channel, and when the first salt water needs to be introduced, the first salt water is introduced into the water softener 100 through the first regeneration channel, and when the second salt water needs to be introduced, the second salt water is introduced into the water softener 100 through the second regeneration channel.

[0089] The regeneration device 600 also has a forward wash channel and a backwash channel. The water softener also has a forward wash state and a backwash state. When the water softener is in the forward wash state, the forward wash channel is connected, and the raw water washes the water softener 100 from top to bottom through the forward wash channel. That is, the raw water flows from the upper water distributor 300 to the lower water distributor 400, and flows out from the lower water distributor 400 through the central tube 500. In this state, the raw water flows from top to bottom through the resin layer in the resin tank 200, and the water pressure slowly precipitates the fluffy resin, exchanges ions, and precipitates dirt at the same time. When the water softener is in the backwash state, the backwash channel is connected, and the raw water washes the water softener 100 from top to bottom through the backwash channel. That is, the raw water flows through the central tube 500 to the lower water distributor 400, and flows from the lower water distributor 400 to the upper water distributor 300. In this state, raw water flows through the resin layer in the resin tank 200 from bottom to top, making the resin fluffy to achieve the purpose of strong flushing (ion exchange).

[0090] The regeneration device 600 includes a salt supply device 700 and an integrated waterway 800, and the integrated waterway 800 is arranged between the salt supply device 700 and the water softening device 100. Saturated salt water is stored in the salt supply device 700, and the soft water supply channel, raw water supply channel, first regeneration channel, second regeneration channel, forward wash channel and backwash channel are all arranged on the integrated waterway 800 and are all connected to the raw water source. When the water softener is in the soft water supply state, the soft water supply channel is connected, and the raw water flowing out of the raw water source can flow into the water softening device 100 through the soft water supply channel, and the soft water softened by the water softening device 100 can flow out through the soft water supply channel for use by the user. When the water softener is in the first regeneration state, the first regeneration channel is connected, and the raw water provided by the raw water source and the saturated salt water provided by the salt supply device 700 are mixed in the first regeneration channel to form the first salt water, and the first salt water is supplied to the water softening device 100 through the first regeneration channel. When the water softener is in the second regeneration state, the second regeneration channel is turned on, and the raw water provided by the raw water source and the saturated brine provided by the salt supply device 700 are mixed in the second regeneration channel to form second brine, and the second brine is supplied to the water softener 100 through the second regeneration channel.

[0091] See also Figure 2 and Figure 3 The first regeneration channel includes a first water channel 11, a first salt channel and a first mixing channel. One end of the first water channel 11, the first salt channel and the first mixing channel are connected at the first intersection. The other end of the first water channel away from the first intersection is connected to the raw water source. The other end of the first salt channel away from the first intersection is connected to the salt supply device 700. The other end of the first mixing channel away from the first intersection is connected to the softening device 100. The cross-sectional area of ​​the first water channel 11 gradually decreases from the other end away from the first intersection to the end close to the first intersection.

[0092] In this way, when the raw water flows through the first water guiding channel 11, since the cross-sectional area of ​​the first water guiding channel 11 gradually decreases from the other end away from the first intersection to the end close to the first intersection, when the raw water flows from the first water guiding channel 11 from the end away from the first mixing channel to the end close to the first mixing channel, the flow rate of the raw water gradually increases, and a first negative pressure is formed. Under the action of the first negative pressure, the saturated brine in the salt supply device 700 flows into the first mixing channel through the first salt guiding channel, and the raw water and the saturated brine are mixed in the first mixing channel to form first brine of a first concentration, and the first brine flows into the softening device 100 through the first mixing channel.

[0093] See also Figure 4 The second regeneration channel includes a second water channel 12, a second salt channel and a second mixing channel. The second water channel 12, the second salt channel and the second mixing channel are connected at the second intersection. The other end of the second water channel 12 away from the second intersection is connected to the raw water source, the other end of the second salt channel away from the second intersection is connected to the salt supply device, and the other end of the second mixing channel away from the second intersection is connected to the second channel. The cross-sectional area of ​​the second water channel 12 gradually decreases from the other end away from the second intersection to the end close to the second intersection.

[0094] In this way, when the raw water flows through the second water guiding channel 12, since the cross-sectional area of ​​the second water guiding channel 12 gradually decreases from the other end away from the second intersection to the end close to the second intersection, when the raw water flows from the second water guiding channel 12 from the end away from the second mixing channel to the end close to the second mixing channel, the flow rate of the raw water gradually increases, and a second negative pressure is formed. Under the action of the second negative pressure, the saturated brine in the salt supply device 700 flows into the second mixing channel through the second salt guiding channel, and the raw water and the saturated brine are mixed in the second mixing channel to form second brine of a second concentration, and the second brine flows into the softening device 100 through the second mixing channel.

[0095] Furthermore, the lengths of the first water channel 11 and the second water channel 12 are equal, the cross-sectional areas of the end of the first water channel 11 away from the first intersection and the end of the second water channel 12 away from the second intersection are equal, and the cross-sectional areas of the end of the first water channel 11 close to the first intersection and the end of the second water channel 12 close to the second intersection are not equal. In this way, the first negative pressure and the second negative pressure are ensured to be different, and the first concentration of the first salt water and the second concentration of the second salt water formed at last are ensured to be different.

[0096] It should be understood that in other embodiments, other configurations may be used to achieve inequality between the first concentration and the second concentration, which is not limited herein.

[0097] In a specific embodiment, the cross-sectional area of ​​one end of the first water guiding channel 11 near the first intersection is set to be larger than the cross-sectional area of ​​one end of the second water guiding channel 12 near the second intersection, so that the first negative pressure is less than the second negative pressure. At this time, more saturated salt water flows into the first mixing channel through the first salt guiding channel, while less saturated salt water flows into the second mixing channel through the second salt guiding channel, and the first concentration is less than the second concentration.

[0098] Continue reading Figure 1 The integrated waterway 800 includes an ejector 10 and a multi-way valve 900, and the ejector 10 is arranged between the multi-way valve 900 and the salt supply device 700. The first water guide channel 11, the first salt guide channel, the second water guide channel 12, the second salt guide channel, the first mixing channel and the second mixing channel are all arranged on the ejector 10. That is, the first water guide channel 11, the first salt guide channel and the first mixing channel are all formed on the ejector 10, and the first water guide channel 11, the first salt guide channel and the first mixing channel jointly form the first ejection channel. The second water guide channel 12, the second salt guide channel and the second mixing channel are all formed on the ejector 10, and the second water guide channel 12, the second salt guide channel and the second mixing channel jointly form the second ejection channel.

[0099] In one embodiment, refer to Figure 5 The ejector 10 includes an ejector body 13, a first nozzle 14, a second nozzle 15 and a cover plate 16. The first nozzle 14 and the second nozzle 15 are both assembled in the ejector body 13, and the cover plate 16 is covered on the ejector body 13. The first water guide channel 11 is formed in the first nozzle 14, the second water guide channel 12 is formed in the second nozzle 15, the first salt guide channel and the second salt guide channel are both formed on the ejector body 13, and the ejector body 13 and the cover plate 16 jointly define a first mixing channel and a second mixing channel. In this way, the formation of the first water guide channel 11, the second water guide channel 12, the first salt guide channel, the second salt guide channel, the first mixing channel and the second mixing channel is facilitated.

[0100] The ejector body 13 includes an ejector body 131 and a first water inlet 132, a second water inlet 133, a first salt inlet 134, a second salt inlet 135, a second water outlet 137 and a second water outlet 137, all of which are connected to the ejector body 131. The first water inlet 132 and the second water inlet 133 are both connected to the raw water source, the first salt inlet 134 and the second salt inlet 135 are both connected to the salt supply device 700, and the first water outlet 136 and the second water outlet 137 are both connected to the multi-way valve 900. The first nozzle 14 is disposed in the first water inlet 132, the second nozzle 15 is disposed in the second water inlet 133, the first salt channel is formed in the first salt inlet 134, and the second salt channel is formed in the second salt inlet 135. The first mixing channel and the second mixing channel have a common channel 17 to simplify the channel setting. Specifically, the cover plate 16 is covered on the ejector body 131, and the two define a common channel 17. The other part of the first mixing channel is formed in the first water outlet 136, and the other part of the second mixing channel is formed in the second water outlet 137.

[0101] The ejector 10 further includes a first throat 18 and a second throat 19. The first throat 18 is at least partially disposed in the first water inlet 132 and is spaced apart from the first nozzle 14. The second throat 19 is at least partially disposed in the second water inlet 133 and is spaced apart from the second nozzle 15. Thus, a first siphon area is formed between the first nozzle 14 and the first throat 18, so that saturated salt water is sucked into the area for mixing under the action of the first negative pressure to form the first salt water. At the same time, a second siphon area is formed between the second nozzle 15 and the second throat 19, so that saturated salt water is sucked into the area for mixing under the action of the second negative pressure to form the second salt water.

[0102] The ejector 10 further includes a first filter screen 110, which is disposed in the first water outlet 136 to filter impurities in the first salt water to ensure the cleanliness of the first salt water flowing to the multi-way valve 900. The ejector 10 further includes a second filter screen 111, which is disposed in the second water outlet 137 to filter impurities in the second salt water to ensure the cleanliness of the second salt water flowing to the multi-way valve 900.

[0103] See also Figure 6 The multi-way valve 900 includes a valve body assembly 20 and a movable valve plate assembly 30. The valve body assembly 20 is assembled on the resin tank 200. The upper water distributor 300 and the end of the central pipe 500 that is not connected to the lower water distributor 400 are connected to the valve body assembly 20. The movable valve plate assembly 30 is movably arranged on the valve body assembly 20 to switch the water softener between the above-mentioned soft water supply state and the non-soft water supply state.

[0104] See also Figure 7 and Figure 8The valve body assembly 20 has a first channel 21, a second channel 22 and a third channel 23 (water inlet channel). The first channel 21 is connected to the first mixing channel, the second channel 22 is connected to the second mixing channel, and the third channel 23 is connected to the water softening device 100. Specifically, the third channel 23 is connected to an end of the central pipe 500 that is not connected to the lower water distributor 400.

[0105] Specifically, the valve body assembly 20 has a first water inlet 24 and a second water inlet 25, a portion of the first channel 21 is formed in the first water inlet 24 or the first channel 21 is connected to the first water inlet 24, a portion of the second channel 22 is formed in the second water inlet 25 or the second channel 22 is connected to the second water inlet 25, the first water inlet 24 is connected to the first water outlet 136 of the ejector 10, and the second water inlet 25 is connected to the second water outlet 137 of the ejector 10. In this way, the first channel 21 is connected to the first mixing channel, and the second channel 22 is connected to the second mixing channel.

[0106] The movable valve plate assembly 30 includes a movable valve plate 31, which can move relative to the valve body assembly 20 to make the third channel 23 communicate with the first channel 21 and the second channel 22 alternatively. The first channel 21 is configured to provide a first salt water having a first concentration to the central tube 500 through the third channel 23, and the second channel 22 is configured to provide a second salt water having a second concentration to the central tube 500 through the third channel 23.

[0107] In the above arrangement, when the water softener needs to switch from the second regeneration state to the first regeneration state, the movable valve plate 31 moves relative to the valve body assembly 20, the third channel 23 is connected with the first channel 21, the first salt water flowing out of the first mixing channel can enter the third channel 23 through the first channel 21, and flow to the central tube 500 through the third channel 23, flow from the central tube 500 to the lower water distributor 400, and flow to the resin in the resin tank 200 through the lower water distributor 400 to regenerate the functional ions. When the water softener needs to switch from the first regeneration state to the second regeneration state, the movable valve plate 31 moves relative to the valve body assembly 20 again, the third channel 23 is connected with the second channel 22, the second salt water flowing out of the second mixing channel can enter the third channel 23 through the second channel 22, and flow to the central tube 500 through the third channel 23, flow from the central tube 500 to the lower water distributor 400, and flow to the resin in the resin tank 200 through the lower water distributor 400 to regenerate the functional ions.

[0108] It should be emphasized here that the first channel 21 and the third channel 23 are both used as a part of the first regeneration channel, and the second channel 22 and the third channel 23 are both used as a part of the second regeneration channel.

[0109] Specifically, the movable valve disc assembly 30 is rotatably mounted on the valve body assembly 20 around an axis, so that the water softener can switch between the soft water supply state and the non-soft water supply state. That is, the movable valve disc 31 is rotatably mounted on the valve body assembly 20 around an axis, so that the water softener can switch between the soft water supply state and the non-soft water supply state. Of course, in other embodiments, the movable valve disc 31 can also be movably connected to the valve body assembly 20 in other motion modes, as long as the water softener can switch between the soft water supply state and the non-soft water supply state.

[0110] See also Fig.10 The axial end surface of the movable valve plate 31 facing the valve body assembly 20 is provided with a guide groove 311. When the water softener is in the first regeneration state, the guide groove 311 connects the first channel 21 with the third channel 23, and when the water softener is in the second regeneration state, the guide groove 311 connects the first channel 21 with the second channel 22.

[0111] Continue reading Figure 7 and Figure 8 The valve body assembly 20 has a fourth channel 26 and a fifth channel 27. The fourth channel 26 is connected to the first water channel 11, and the fifth channel 27 is connected to the second water channel 12. Raw water flows into the first water channel 11 through the fourth channel 26, and flows into the second water channel 12 through the fifth channel 27. In this way, the channel for introducing raw water into the ejector 10 is set on the valve body assembly 20, which simplifies the structure of the integrated waterway 800.

[0112] The valve body assembly 20 has a first water receiving outlet 28 and a second water receiving outlet 29, a portion of the fourth channel 26 is disposed in the first water receiving outlet 28 or the fourth channel 26 is communicated with the first water receiving outlet 28, a portion of the fifth channel 27 is disposed in the second water receiving outlet 29 or the fifth channel 27 is communicated with the second water receiving outlet 29. The first water receiving outlet 28 is connected to the first water guide inlet 132 of the ejector 10 so that the fourth channel 26 is communicated with the first water guide channel 11, and the second water receiving outlet 29 is connected to the second water guide inlet 133 of the ejector 10 so that the fifth channel 27 is communicated with the second water guide channel 12.

[0113] The valve body assembly 20 has a sixth channel 210 (water inlet channel) directly connected to the raw water source. When the third channel 23 is connected to the first channel 21, the fourth channel 26 is connected to the sixth channel 210, and the raw water flows to the fourth channel 26 through the sixth channel 210, and flows from the fourth channel 26 to the first water guide channel 11. When the third channel 23 is connected to the second channel 22, the fifth channel 27 is connected to the sixth channel 210, and the raw water flows to the fifth channel 27 through the sixth channel 210, and flows from the fifth channel 27 to the second water guide channel 12. In this way, the channel for directly introducing raw water is set on the valve body assembly 20, which can further simplify the structure of the integrated waterway 800.

[0114] The valve body assembly 20 has a raw water interface 211 , which is connected to a raw water source. Part of the sixth channel 210 is disposed in the raw water interface 211 or the sixth channel 210 is connected to the raw water source through the raw water interface 211 .

[0115] It should be noted that the sixth channel 210 and the fourth channel 26 are part of the first regeneration channel, and the sixth channel 210 and the fifth channel 27 are part of the second regeneration channel.

[0116] For further information, see Fig.11 and Fig.12 A water inlet groove 312 is provided on the movable valve plate 31. When the third channel 23 is connected to the first channel 21, the water inlet groove 312 is connected to the fourth channel 26 and the sixth channel 210. When the third channel 23 is connected to the second channel 22, the water inlet groove 312 is connected to the fifth channel 27 and the sixth channel 210.

[0117] Continue reading Figure 7 and Figure 8 The valve body assembly 20 has a seventh channel 212 (water outlet channel). When the water softener is in the first regeneration state and the second regeneration state, that is, the third channel 23 is connected to the first channel 21, or the third channel 23 is connected to the second channel 22, the seventh channel 212 is connected to the sixth channel 210, that is, the water outlet channel is connected to the water inlet channel. At this time, the water softener can supply raw water to achieve continuous flow.

[0118] The valve body assembly 20 has a water outlet interface 213 , which is connected to an external water outlet pipe. Part of the seventh channel 212 is disposed in the water outlet interface 213 or the seventh channel 212 is connected to an external water outlet pipe through the water outlet interface 213 .

[0119] The valve body assembly 20 also has an eighth channel 214, which is connected to the upper water distributor 300 in the resin tank 200. When the water softener is in the soft water supply state, the water inlet trough 312 connects the sixth channel 210 and the eighth channel 214, the third channel 23 connects the seventh channel 212, and the seventh channel 212 is cut off from the sixth channel 210. At this time, the raw water flows from the raw water source to the sixth channel 210, flows from the sixth channel 210 to the eighth channel 214, and flows to the upper water distributor 300 through the eighth channel 214. The upper water distributor 300 evenly distributes the raw water in the resin in the resin tank 200, and the calcium and magnesium ions in the raw water are exchanged and precipitated with the sodium ions in the resin to become soft water. The soft water flows to the central pipe 500 through the lower water distributor 400, and flows from the central pipe 500 to the third channel 23, and finally enters the seventh channel 212 and flows out to supply soft water. At this time, since the seventh channel 212 is cut off from the sixth channel 210 , the seventh channel 212 does not supply raw water, that is, the water softener does not supply raw water when supplying softened water.

[0120] Continue reading Fig. 9 The valve body assembly 20 includes a valve body 215 and a fixed valve plate 216. The valve body 215 has a valve cavity 2151 (see Fig.13 ), the fixed valve plate 216 is arranged in the valve cavity 2151, and the first to eighth channels 21 to 214 are all opened on the valve body 215 and the fixed valve plate 216. That is, part of the first to eighth channels 21 to 214 are formed on the valve body 215, and the remaining part is formed on the fixed valve plate 216. Specifically, the first water inlet 24, the second water inlet 25, the first water outlet 28, the second water outlet 29, the raw water interface 211 and the water outlet interface 213 are all arranged on the valve body 215.

[0121] It should be understood that in other embodiments, the valve body assembly 20 may omit the fixed valve plate 216 . In this case, the first channel 21 to the eighth channel 214 are all formed on the valve body 215 , which is not limited here.

[0122] The valve body 215 has an opening communicating between the outside and the valve cavity 2151, and the fixed valve plate 216 is arranged on the bottom wall of the valve cavity 2151 opposite to the opening. Fig.14 and Fig.15 The fixed valve plate 216 has a first flow control plane 2161 and a second flow control plane 2162. The first flow control plane 2161 and the second flow control plane 2162 are opposite to each other in the axial direction. The first flow control plane 2161 of the fixed valve plate 216 abuts against the bottom wall of the valve cavity 2151. Figure 16-Figure 18The valve body assembly 20 also includes a valve core nut 217, which is arranged in the valve cavity 2151. The valve core nut 217, the fixed valve plate 216 and the valve body 215 define an assembly cavity. The movable valve plate assembly 30 also includes a valve stem 32. The movable valve plate 31 is arranged in the assembly cavity and abuts against the second flow control plane 2162 of the fixed valve plate 216 in the axial direction. The guide groove 311 is arranged on the end surface of the movable valve plate 31 facing the fixed valve plate 216.

[0123] The valve stem 32 is inserted into the valve core nut 217 and connected to the movable valve plate 31. The valve stem 32 can rotate around its own axis relative to the valve core nut 217 to drive the movable valve plate 31 to move, so that the water softener can switch between the soft water supply state and the non-soft water supply state.

[0124] The valve body assembly 20 and the movable valve plate assembly 30 define a connecting cavity 40, and the connecting cavity 40 connects the water inlet groove 312 of the movable valve plate 31 and the sixth channel 210. That is, the water inlet groove 312 is connected to the sixth channel 210 through the connecting cavity 40. The water inlet groove 312 is opened at the edge of the movable valve plate 31 (see Fig.19 ), so as to communicate with the communication chamber 40. The sixth channel 210, the communication chamber 40 and the seventh channel 212 together form a raw water supply channel, that is, the raw water supply channel is a waterway provided on the valve body assembly 20 and the movable valve plate assembly 30.

[0125] See also Fig.19 and Fig. 20 The movable valve plate 31 includes a plate body 313 and a truncation portion 314 extending radially outside the plate body 313. The guide groove 311 and the water inlet groove 312 are both provided on the plate body 313. The water inlet groove 312 is provided at the radial edge of the plate body 313 so that the water in the communication chamber 40 flows to the water inlet groove 312. Specifically, the water inlet groove 312 is a blind groove provided on the axial end surface of the plate body 313 facing the fixed valve plate 216, that is, the water inlet groove 312 is not provided axially through the plate body 313. The width of the water inlet groove 312 gradually increases from one end close to the center of the plate body 313 to the other end, so that the water inlet groove 312 forms a larger entrance, which facilitates water to enter the water inlet groove 312.

[0126] When the water softener is in the soft water supply state, the cutoff portion 314 cuts off the connection of the raw water supply channel. Specifically, when the water softener is in the soft water supply state, the cutoff portion 314 cuts off the connection between the seventh channel 212 and the communication chamber 40. In this way, when the raw water flows from the sixth channel 210 to the communication chamber 40, it cannot flow to the seventh channel 212. When the water softener is in the non-soft water supply state, the cutoff portion 314 allows the raw water supply channel to be connected. Specifically, when the water softener is in the non-soft water supply state, the cutoff portion 314 allows the seventh channel 212 to be connected to the communication chamber 40. In this way, when the raw water flows from the sixth channel 210 to the communication chamber 40, it can flow out from the communication chamber 40 to the seventh channel 212 to achieve continuous flow.

[0127] See also Fig.21 The first channel 21 to the eighth channel 214 all have an opening disposed on the second flow control plane 2162 of the fixed valve plate 216 .

[0128] Specifically, the first channel 21 has a first port A, the second channel 22 has a second port B, the third channel 23 has a third port, the fourth channel 26 has a fourth port D, the fifth channel 27 has a fifth port E, the sixth channel 210 has a sixth port F, the seventh channel 212 has a seventh port G (port), and the eighth channel 214 has an eighth port H. It should be noted that, in this embodiment, the fixed valve plate 216 and the valve body 215 are separately provided, and eight ports are also provided on the valve body 215 at this time, and these eight ports are respectively opposite to the first port A to the eighth port H. Specifically, the size of these eight ports is equal to that of the first port A to the eighth port H. It should be understood that in other embodiments, the size of these eight ports may be different from that of the first port A to the eighth port H, and this is not limited here.

[0129] Furthermore, the third port includes a first sub-port C1 and a second sub-port C2 that are arranged at intervals. In the circumferential direction of the fixed valve plate 216, the first port A, the second port B, the eighth port H, the first sub-port C1, the fourth port D, the fifth port E, the seventh port G and the second sub-port C2 are arranged at intervals in sequence. The sixth port F is arranged at the circumference of the fixed valve plate 216, and in the radial direction of the fixed valve plate 216, the sixth port F is opposite to the first port A and the second port B.

[0130] In one embodiment, continue to refer to Figure 7 The valve body assembly 20 has a ninth channel 218 (drainage channel). Specifically, the ninth channel 218 is opened on the valve body 215. The valve body 215 is provided with a drainage interface connected to an external drainage pipe. Part of the ninth channel 218 is arranged in the drainage interface or the ninth channel 218 is connected to the external drainage pipe through the drainage interface.

[0131] Continue reading Fig.10The sheet body 313 of the movable valve sheet 31 is provided with a drainage groove 315. When the water softener is in the first regeneration state and the second regeneration state, the drainage groove 315 connects the eighth channel 214 and the ninth channel 218. Wastewater discharged from the water softener 100 flows to the drainage groove 315 through the eighth channel 214, and flows to the ninth channel 218 through the drainage groove 315 for discharge. Specifically, the ninth channel 218 has a ninth port I opened on the inner wall of the valve body 215, and the drainage groove 315 connects the eighth port H and the ninth port I.

[0132] The valve stem 32 and the valve core nut 217 define a conducting cavity 50 (see Fig.18 ), the conducting cavity 50 conducts the drain groove 315 and the ninth channel 218. The valve stem 32 includes a stem body 321 and an inner part 322 (see Fig.17 ), the rod body 321 is connected to the movable valve plate 31, the inner part 322 is arranged in the rod body 321, and the rod body 321, the inner part 322 and the valve core nut 217 define a conducting cavity 50. The drainage groove 315 includes a first drainage groove 3151 and a second drainage groove 3152 that are interconnected (see Fig.10 ), the first drainage groove 3151 axially penetrates the center position of the movable valve plate 31, one end of the second drainage groove 3152 is connected to the first drainage groove 3151, and the other end extends radially along the plate body 313, and the second drainage groove 3152 is not axially penetrated through the movable valve plate 31, but is arranged on the axial end face of the movable valve plate 31 facing the fixed valve plate 216.

[0133] The non-soft water supply state also includes a slow wash state. When the water softener is in the slow wash state, the regeneration device 600 provides raw water to the water softener 100 for slow washing. Specifically, the speed at which the regeneration device 600 provides raw water to the water softener 100 is less than the speed at which the regeneration device 600 provides salt water to the water softener 100 when the water softener is in the first regeneration state and the second regeneration state. In this way, after the water softener is in the first regeneration state, it switches to the slow wash state. At this time, the regeneration device 600 can provide raw water at a slower speed to the water softener 100. When the water softener is in the second regeneration state, it switches to the slow wash state. At this time, the regeneration device 600 can provide raw water at a slower speed to the water softener 100. The use of the regeneration state in combination with the slow wash state can improve the utilization rate of the salt solution.

[0134] See also Fig. 22 and Fig.23The fixed valve plate 216 and the valve body 215 define a latent channel 219 for slow washing, and the fixed valve plate 216 is provided with a water inlet and a water outlet J both connected to the latent channel 219. When the water softener 100 needs to be slowly washed, the water inlet tank 312 is connected to the water inlet, and the raw water flows to the connecting cavity 40 through the sixth channel 210, and flows from the connecting cavity 40 to the water inlet tank 312 to enter the water inlet, flows from the water inlet to the latent channel 219, flows from the latent channel 219 to the water outlet J, and flows to the water softener 100 through the water outlet J for slow washing. In this way, it is avoided to set up another pipeline for slow washing of the water softener 100, and the structure of the water softener is simplified.

[0135] In one embodiment, a groove 2163 is formed on the first flow control plane 2161 of the fixed valve plate 216 (see Fig.14 ), the groove wall of the groove 2163 and the valve body 215 form a latent channel 219, and in the extension direction of the groove 2163, the water inlet and the water outlet J are respectively arranged at the two ends of the groove 2163. In another embodiment, the surface of the valve body 215 facing the fixed valve plate 216 is provided with a groove 2163, and the groove wall of the groove 2163 and the second flow control plane 2162 of the fixed valve plate 216 form a latent channel 219. In another embodiment, the surfaces of the fixed valve plate 216 and the valve body 215 facing each other are both provided with grooves 2163, and the groove walls of the two grooves 2163 form a latent channel 219.

[0136] The water inlet and the fourth port D are the same port, so as to further simplify the structure of the water softener. In the extension direction of the latent channel 219, the water inlet and the water outlet J are respectively arranged at the two ends of the latent channel 219. In this way, when the latent channel 219 extends in a straight line and the water inlet and the fourth port D are the same port, the water outlet J is located between the first port A and the second port B in the circumferential direction of the fixed valve plate 216, so that when the water softener is in a slow wash state, the water guide groove connects the water outlet J with the second sub-port C2, so that the raw water flows from the water outlet J to the second sub-port C2 to flow into the water softening device 100 through the third channel 23 to wash the resin layer from bottom to top.

[0137] The line connecting the water inlet and the center point of the fixed valve plate 216 is defined as the first line, the line connecting the water outlet J and the center point of the fixed valve plate 216 is defined as the second line, and the angle formed between the first line and the second line is greater than 90° and less than 180°. In this way, the distance between the water inlet and the water outlet J in the circumferential direction of the fixed valve plate 216 can be made larger, so as to facilitate the arrangement of other ports on the fixed valve plate 216, thereby ensuring that the various states of the water softener will not interfere with each other.

[0138] There is a distance between the guide groove 311 and the center point of the movable valve plate 31, so that the position of the guide groove 311 on the movable valve plate 31 corresponds to the position of each of the above-mentioned ports on the fixed valve plate 216, thereby facilitating the guide groove 311 to connect two of the above-mentioned ports. Fig.10 The guide groove 311 includes a first guide portion 3111, a second guide portion 3112 and a third guide portion 3113 which are sequentially connected in the circumferential direction of the plate body 313, and a barrier portion 316 is formed between the first guide portion 3111 and the third guide portion 3113. In the radial direction of the movable valve plate 31, the barrier portion 316 is located on one side of the second guide portion 3112. In this arrangement, when the guide groove 311 connects two ports, the barrier portion 316 can block the remaining ports between the two ports connected by the guide groove 311, so that the water softener can operate normally between various states.

[0139] For example, when the guide groove 311 connects the second sub-port C2 and the second port B, the blocking portion 316 can cover the first port A and the water outlet J to prevent the first port A from connecting to the second sub-port C2 or the second port B, and to prevent the water outlet J from connecting to the second sub-port C2 or the second port B. When the guide groove 311 connects the second sub-port C2 and the water outlet J, the blocking portion 316 can cover the first port A to prevent the first port A from connecting to the second sub-port C2 or the water outlet J.

[0140] Specifically, in the radial direction of the sheet body 313, the barrier portion 316 is located outside the second guide portion 3112. It should be understood that in other embodiments, in the radial direction of the sheet body 313, the barrier portion 316 can also be disposed inside the second guide portion 3112, which is not limited here.

[0141] The outer contour of the guide groove 311 is located in a virtual sector, and the guide groove 311 forms a "door"-shaped guide groove 311, so that when the guide groove 311 connects two ports, the blocking portion 316 can block the remaining ports between the two ports connected by the guide groove 311. Of course, in other embodiments, the shape of the guide groove 311 is not limited.

[0142] In the radial direction of the movable valve plate 31, the cut-off portion 314 extends to the outer peripheral edge of the plate body 313 where the guide groove 311 is provided. Specifically, the extending length of the cut-off portion 314 in the circumferential direction of the movable valve plate 31 is greater than the extending length of the first guide portion 3111 in the circumferential direction of the movable valve plate 31, so that when the first guide portion 3111 is connected with the seventh port G, the cut-off portion 314 can cover the portion where the seventh port G is connected with the connecting chamber 40, thereby avoiding mixing of raw water when supplying soft water.

[0143] The working principle of the water softener provided in the embodiment of the present application is as follows:

[0144] The valve stem 32 rotates and the movable valve plate 31 is linked. When the movable valve plate 31 moves relative to the fixed valve plate 216, the openings on the fixed valve plate 216 connected to the water inlet groove 312 are different, and the openings connected to the guide groove 311 are different, so that the multi-way valve 900 is switched between the soft water supply position, the first regeneration position, the second regeneration position, the forward washing position, the backwashing position, the slow washing position and the salt supply device water replenishment position. Accordingly, the water softener is switched between the soft water supply state, the first regeneration state, the second regeneration state, the forward washing state, the backwashing state, the slow washing state and the salt supply device water replenishment state.

[0145] In order to facilitate the description of each state, the seventh port G is defined as including a first portion G1 and a second portion G2 connected to each other in the radial direction (see Fig.23 ), the second portion G2 is arranged relative to the first portion G1 and away from the center point of the fixed valve plate 216.

[0146] In soft water supply state (see Fig.24 ):

[0147] The water inlet groove 312 is connected to the eighth port H, the guide groove 311 is connected to the second sub-port C2 and the first part G1 of the seventh port G, and the cut-off portion 314 covers the second part G2 of the seventh port G. The sixth channel 210, the connecting cavity 40, the eighth channel 214, the third channel 23 and the seventh channel 212 form a soft water supply channel. The raw water supply channel formed by the sixth channel 210, the connecting cavity 40 and the seventh channel 212 is cut off.

[0148] The raw water flows through the sixth channel 210, the connecting chamber 40 and the eighth channel 214 in sequence to the upper water distributor 300. The upper water distributor 300 sprays water into the resin in the resin tank 200. The calcium and magnesium ions in the raw water are exchanged with the functional ions on the resin to form soft water, and flow to the central pipe 500 through the lower water distributor 400. The soft water flowing out of the central pipe 500 flows to the seventh channel 212 through the third channel 23 to supply soft water.

[0149] In the first regeneration state (see Fig.25 ):

[0150] The water inlet groove 312 is connected to the fourth port D, the guide groove 311 is connected to the first port A and the second sub-port C2, and the drainage groove 315 is connected to the eighth port H. At this time, the second part G2 of the seventh port G is connected to the connecting chamber 40. The sixth channel 210, the connecting chamber 40, the fourth channel 26, the first jet channel, the first channel 21, the third channel 23, the eighth channel 214, the conducting chamber 50 and the ninth channel 218 form a first regeneration channel. The raw water supply channel formed by the sixth channel 210, the connecting chamber 40 and the seventh channel 212 is connected.

[0151] The raw water flows sequentially through the sixth channel 210, the connecting chamber 40, the fourth channel 26, the first jet channel, the first channel 21 and the third channel 23 to the central tube 500, flows through the central tube 500 to the lower water distributor 400, and is sprayed on the resin in the resin tank 200 through the lower water distributor 400. The salt water passes through the failed resin to replace the calcium and magnesium ions therein into the solution. The waste water formed after the replacement flows to the upper water distributor 300, and flows sequentially from the upper water distributor 300 to the eighth channel 214, the drainage groove 315, the conduction chamber 50 and the ninth channel 218 for discharge. At this time, since the raw water supply channel is connected, the raw water can be discharged from the sixth channel 210 to the connecting chamber 40, and through the connecting chamber 40 to the seventh channel 212.

[0152] In the second regeneration state (see Fig.26 ):

[0153] The water inlet groove 312 is connected to the fifth port E, the guide groove 311 is connected to the second port B and the second sub-port C2, and the drainage groove 315 is connected to the eighth port H. At this time, the second part G2 of the seventh port G is connected to the connecting chamber 40. The sixth channel 210, the connecting chamber 40, the fifth channel 27, the second jet channel, the second channel 22, the third channel 23, the eighth channel 214, the guide chamber and the ninth channel 218 form a second regeneration channel. The raw water supply channel formed by the sixth channel 210, the connecting chamber 40 and the seventh channel 212 is connected.

[0154] The raw water flows sequentially through the sixth channel 210, the connecting chamber 40, the fifth channel 27, the second jet channel, the second channel 22 and the third channel 23 to the central tube 500, flows through the central tube 500 to the lower water distributor 400, and is sprayed on the resin in the resin tank 200 through the lower water distributor 400. The salt water passes through the failed resin to replace the calcium and magnesium ions therein into the solution. The waste water formed after the replacement flows to the upper water distributor 300, and flows sequentially from the upper water distributor 300 to the eighth channel 214, the drainage groove 315, the conduction chamber 50 and the ninth channel 218 for discharge. At this time, since the raw water supply channel is connected, the raw water can be discharged from the sixth channel 210 to the connecting chamber 40, and through the connecting chamber 40 to the seventh channel 212.

[0155] In the slow wash state (see Fig. 27 ):

[0156] The water inlet groove 312 is connected to the fourth port D, the diversion groove 311 is connected to the water outlet J and the second sub-port C2, and the drainage groove 315 is connected to the eighth port H. At this time, the second part G2 of the seventh port G is connected to the connecting cavity 40. The sixth channel 210, the connecting cavity 40, the fourth port D, the latent channel 219, the water outlet J, the third channel 23, the eighth channel 214, the diversion cavity and the ninth channel 218 form a slow wash channel. The raw water supply channel formed by the sixth channel 210, the connecting cavity 40 and the seventh channel 212 is connected.

[0157] The raw water flows sequentially through the sixth channel 210, the connecting chamber 40, the fourth port D, the latent channel 219, the water outlet J and the third channel 23 to the central tube 500, flows through the central tube 500 to the lower water distributor 400, and flows from the lower water distributor 400 through the resin layer to the upper water distributor 300, slowly washing the resin layer from bottom to top, taking away the broken resin and residual dirt, and the waste water flows sequentially from the upper water distributor 300 to the eighth channel 214, the drainage groove 315, the conduction chamber 50 and the ninth channel 218 for discharge. At this time, since the raw water supply channel is connected, the raw water can flow from the sixth channel 210 to the connecting chamber 40, and be discharged from the connecting chamber 40 to the seventh channel 212.

[0158] In the washing state (see Fig.28 ):

[0159] The water inlet groove 312 is connected to the eighth port H, the water outlet groove 315 is connected to the second sub-port C2, and the second portion G2 of the seventh port G is connected to the connecting chamber 40. The sixth channel 210, the connecting chamber 40, the eighth channel 214, the third channel 23, the conducting chamber 50 and the ninth channel 218 form a forward wash channel. The raw water supply channel formed by the sixth channel 210, the connecting chamber 40 and the seventh channel 212 is connected.

[0160] The raw water flows through the sixth channel 210, the connecting chamber 40 and the eighth channel 214 in sequence, and flows to the lower water distributor 400 through the upper water distributor 300, and flows out from the lower water distributor 400 through the central tube 500. The raw water flows through the resin layer in the resin tank 200 from top to bottom. The water pressure slowly precipitates the fluffy resin, exchanges ions, and precipitates dirt at the same time. The waste water flows from the central tube 500 to the third channel 23, the drainage groove 315, the conduction chamber 50 and the ninth channel 218 in sequence for discharge. At this time, since the raw water supply channel is connected, the raw water can be discharged from the sixth channel 210 to the connecting chamber 40, and then to the seventh channel 212 through the connecting chamber 40.

[0161] In the backwash state (see Fig.29 ):

[0162] The water inlet groove 312 is connected to the first sub-port C1, the water outlet groove 315 is connected to the eighth port H, and the second part G2 of the seventh port G is connected to the connecting chamber 40. The sixth channel 210, the connecting chamber 40, the third channel 23, the eighth channel 214, the conducting chamber 50 and the ninth channel 218 form a positive wash channel. The raw water supply channel formed by the sixth channel 210, the connecting chamber 40 and the seventh channel 212 is connected.

[0163] The raw water flows through the sixth channel 210, the connecting chamber 40 and the third channel 23 in sequence, and flows to the lower water distributor 400 through the central tube 500, and flows out from the lower water distributor 400 to the upper water distributor 300. The raw water flows through the resin layer in the resin tank 200 from bottom to top, making the resin fluffy to achieve the purpose of strong flushing (ion exchange), and the waste water flows from the upper water distributor 300 to the eighth channel 214, the conducting chamber 50 and the ninth channel 218 in sequence for discharge. At this time, since the raw water supply channel is connected, the raw water can be discharged from the sixth channel 210 to the connecting chamber 40, and then to the seventh channel 212 through the connecting chamber 40.

[0164] When the salt supply device is replenishing water (see Fig.30 ):

[0165] When the salt water reserve in the salt supply device 700 is insufficient, it is necessary to replenish raw water into the salt supply device 700 and add salt into the raw water so as to form sufficient saturated salt water in the salt supply device 700.

[0166] The water inlet tank 312 is connected to the second port B, and the sixth channel 210, the connecting chamber 40, the second channel 22, the second mixing channel and the salt conducting channel (including the first salt conducting channel and the second salt conducting channel) form a water replenishment channel for the salt supply device 700. The raw water supply channel formed by the sixth channel 210, the connecting chamber 40 and the seventh channel 212 is connected.

[0167] The raw water flows through the sixth channel 210, the connecting chamber 40, the second channel 22, the second mixing channel and the salt guiding channel to the salt supply device 700 in sequence, so as to replenish sufficient raw water to the salt supply device 700. At this time, since the raw water supply channel is connected, the raw water can flow from the sixth channel 210 to the connecting chamber 40, and then be discharged to the seventh channel 212 through the connecting chamber 40.

[0168] Specifically, the first concentration is less than the second concentration, and the water softener performs a first regeneration state and a second regeneration state sequentially.

[0169] In this way, when the functional ions in the water softening device 100 need to be regenerated, the water softener first performs the first regeneration state and then performs the second concentration regeneration state, that is, firstly low-concentration salt water is introduced into the water softening device 100, and then high-concentration salt water is introduced. In this way, low concentration and high concentration are carried out in sequence, which can reduce the waste of salt solution while improving the regeneration rate of functional ions.

[0170] Specifically, the third channel 23 on the control multi-way valve 900 is connected with the first channel 21 and the second channel 22 in sequence.

[0171] Further, the slow wash state is executed after the first regeneration state and / or the second regeneration state. Specifically, after the first regeneration state, the water softener is in the slow wash state, and after the second regeneration state, the water softener is in another slow wash state. That is, after each regeneration state, the water softener is switched to the slow wash state, so that the resin layer can be slowly rinsed from bottom to top, the broken resin and residual dirt can be taken away, and the utilization rate of the salt solution can be improved. It should be understood that in other embodiments, when the first regeneration state and the second regeneration state are performed sequentially, it is also possible to choose to perform slow washing after the first regeneration state and not perform slow washing after the second regeneration state, or not perform slow washing after the first regeneration state and perform slow washing after the second regeneration state.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
