[0079] The water mixing method, water softener valve and water softener of the embodiment of the present application are described below with reference to Figures 1 to 21.

[0080] 14 , a water softener according to an embodiment of the present application includes a softening valve for the water softener, a resin assembly 800 and a salt absorption and sewage discharge device 900 . The resin assembly 800 is provided with a water channel component 810 for water circulation. One side of the salt absorption and sewage discharge device 900 is connected to the water channel component 810 , and the other side of the salt absorption and sewage discharge device 900 is connected to the softening valve.

[0081] Through the above design, the water channel component 810 on the resin component 800 can allow water to flow through the resin component 800 during the softening process to remove hardness ions in the water, and one side of the salt absorption and sewage discharge device 900 is connected to the water channel component 810. Its function is to perform brine flushing and sewage discharge after the resin component 800 is saturated to restore the softening ability of the resin component 800. The other side of the salt absorption and sewage discharge device 900 is connected to the soft water valve, which is responsible for controlling the inlet and outlet of liquids such as softened water and brine, thereby realizing the normal operation of the water softener. The above design can effectively soften water quality, reduce the hardness components in water, and improve water quality.

[0082] In some embodiments, the water softener further comprises a salt tank A, and through the operation of the water softener valve, the water softener has a service state, a salt absorption state, a bypass state, a backwash state, a water replenishment state, a slow wash state and a water mixing state.

[0083] 1 , an embodiment of the present application provides a water mixing method for a water softener. The water softener has a first water path and a second water path. The water quality flowing through the first water path and the second water path is different. The water mixing method includes the following steps:

[0084] Step S110, obtaining a water mixing instruction;

[0085] Step S120, determining the water mixing ratio corresponding to the water mixing instruction according to the water mixing instruction;

[0086] Step S130 , controlling the communication between the first water channel and the second water channel, and adjusting the flow rate ratio of the first water channel and the second water channel based on the mixed water ratio to output mixed water.

[0087] According to the water mixing method for a water softener according to the embodiment of the present application, the connection between the first water channel and the second water channel is controlled according to a water mixing instruction, and the flow rate ratio between the two water channels is adjusted to achieve a desired water mixing ratio. In this way, the water softener can effectively mix water flows of different water qualities, meet the user's specific water quality requirements, and provide a mixed water output that meets the requirements. It can flexibly and accurately control water quality and provide users with high-quality mixed water.

[0088] In this embodiment, the water softener receives a water mixing instruction sent by the control system, determines the water mixing ratio according to the water mixing instruction, that is, the ratio of the first water channel and the second water channel during the mixing process, and mixes the water flow at the intersection of the first water channel and the second water channel according to the water mixing ratio, and outputs the mixed water.

[0089] 1 to 5 , in an embodiment of the present application, the water softener includes a water softening valve that controls the communication between the first water channel and the second water channel, and adjusts the flow rate ratio of the first water channel and the second water channel based on the mixed water ratio. Outputting mixed water includes:

[0090] Step S131, determining the working parameters of the soft water valve based on the structural parameters of the soft water valve;

[0091] Step S132, determining a target operating time of the water softening valve based on the operating parameters of the water softening valve and the water mixing ratio;

[0092] Step S133: Based on the target time, control the soft water valve to output mixed water.

[0093] Through steps S131, S132, and S133, the water mixing method is performed by the water softener valve. The water softener valve regulates the flow path of the water softener through the water mixing method, and switches between various functional states through the water softener valve. It can be understood that the operation of the water softener valve enables the water softener to function in a service state for producing softened water, a salt absorption state, a bypass state, a backwash state, a water replenishment state, a slow wash state, and a mixed water state for mixing softened water with unsoftened raw water. By analyzing the structural parameters of the water softener, including parameters such as opening degree and flow control, the working parameters of the water softener during the water mixing process are determined. Combined with the working parameters of the water softener and the required water mixing ratio, the target working time of the water softener is calculated to ensure that the water flow is mixed according to the set ratio during the water mixing process. According to the calculated target time, the water softener adjusts its own working state during the water mixing process, controls the flow rate and mixing ratio of the water flow, and finally outputs mixed water that meets the requirements, providing the water quality output required by the user. This can ensure the stability and accuracy of the water softener during the water mixing process and meet the user's water quality requirements.

[0094] 2 to 4 and 7 , in an embodiment of the present application, the soft water valve includes a rotating gear 220 that implements a setting action by rotating. The operating parameters include the rotation time of the rotating gear 220 and the number of rotating teeth of the rotating gear 220. In step S132, based on the operating parameters of the soft water valve and the mixed water ratio, determining the target operating time of the soft water valve includes:

[0095] Step S1321, obtaining the total number of teeth of the rotating gear 220;

[0096] Step S1322, determining the rotation time of the rotating gear 220 for one rotation;

[0097] Step S1323, determining a preset time for the rotating gear 220 to rotate one tooth based on the total number of teeth and the rotation time;

[0098] Step S1324, determining the number of rotating teeth corresponding to the rotating gear 220 based on the water mixing ratio;

[0099] Step S1325 , determining a target operating time of the soft water valve based on the preset time and the number of rotating teeth.

[0100] Through the above steps, the use of rotating gear 220 effectively achieves motion transmission, speed change, and torque regulation. By accurately calculating the rotation time and preset time of rotating gear 220, the accuracy and stability of the water softener can be ensured. The water softener can accurately calculate the target time required for each tooth of the rotating gear 220 during the water mixing process based on the operating parameters of the rotating gear 220 and the water mixing ratio of the water softener. This ensures that the water softener accurately mixes the water flow according to the set water mixing ratio, providing the water quality output required by the user. This ensures the stability and accuracy of the water softener during the water mixing process and provides high-quality mixed water.

[0101] 6 and 7 , in the embodiment of the present application, the water softener valve has a service position and a water mixing limit position for softening water. In step S1325 , determining the target time for the water softener valve to operate based on the preset time and the number of rotating teeth includes:

[0102] Based on the preset time for each rotation of the rotating gear 220 by one tooth;

[0103] Based on the water mixing ratio, the rotating gear 220 rotates from a position corresponding to the service position to a position corresponding to the water mixing limit position, and the number of teeth of the rotating gear 220 after rotation is obtained;

[0104] Based on the number of teeth that the rotating gear 220 rotates, the target time for the soft water valve to operate is determined.

[0105] First, based on the preset time for the rotating gear 220 to rotate one tooth each time, the preset time required for each tooth of the rotating gear 220 in the water mixing process is calculated; secondly, based on the water mixing ratio, the position of the rotating gear 220 from the position corresponding to the service position to the position corresponding to the water mixing limit position is calculated. This position is determined by the set opening and closing angle formed by the service position and the water mixing limit position. By calculating the required preset number of teeth, the position to which the rotating gear 220 needs to be rotated can be determined; next, based on the number of teeth rotated by the rotating gear 220 and the preset time for each tooth, the target time required for the number of teeth after rotation is calculated; thereby, the soft water valve can accurately adjust the water mixing ratio. The user can input the required water mixing hardness, and the soft water valve will work according to the target time corresponding to the water mixing hardness to obtain corresponding mixed water, ensuring that the output water quality is stable and meets the user's requirements; at the same time, by using the rotating gear 220 to realize rotation control, the accuracy and reliability of the soft water valve can be ensured, thereby improving the overall performance of the water softener.

[0106] 1 to 5 , an embodiment of the present application provides a water softener valve, which implements the aforementioned water mixing method for a water softener.

The control unit 200 has a water flow control function with a service position and a water mixing limit position. When the control unit 200 is at the water mixing limit position, the first waterway and the second waterway are connected, and the flow ratio of the first waterway and the second waterway is controlled. The flow ratio between soft water and raw water is adjusted: by rotating the control unit 200, the water softener valve system can adjust the degree of connectivity between the first waterway and the second waterway, thereby adjusting the flow ratio of soft water to raw water. By adopting the above structure, by controlling the flow ratio of the first water channel and the second water channel, the soft water valve can accurately control the output flow of soft water to meet the needs of users; the soft water valve system can flexibly adjust the ratio of soft water and raw water according to different scenarios and needs, thereby adapting to various water quality requirements and usage scenarios.

With the above structure, in the mixed water state, a portion of the raw water reaches the chamber 110 of the valve body 100 through the water inlet channel 120, and then reaches the resin assembly 800 through the water outlet chamber 320 and the tank inlet channel 140, and reaches the water outlet after being softened. The other portion of the raw water reaches the backwash chamber 340 and reaches the water outlet through the backwash channel 170. The two portions of water are mixed, thereby realizing multifunctional water treatment operations and waterway control.

One side of the sealing structure 500 abuts against the fixed plate 400, and the other side of the sealing structure 500 abuts against the support structure 300, thereby improving the sealing performance between the two.

[0120] Specifically, in the embodiment of the present application, the sealing structure 500 is a sealing gasket, which can provide a certain friction force between the support structure 300 and the fixed plate 400, which is beneficial to prevent the fixed plate 400 from rotating relative to the support structure 300 and improve working stability.

It can be understood that the brine absorption chamber 330 is located inwardly of the support structure 300, and the backwash chamber 340 is located outwardly of the support structure 300. Through this arrangement, the brine absorption flow rate is relatively small relative to the backwash flow rate according to flow rate requirements, which is convenient for manufacturing and processing, and facilitates the operation of the soft water valve.

[0122] 8 and 9 , in the embodiment of the present application, the support structure 300 is a support column protruding from the chamber 110. This arrangement prevents direct contact between the surface plate 400 and the bottom wall of the chamber 110, further improves the structural strength of the support structure 300, and facilitates assembly and removal of the surface plate 400 from the chamber 110, making operation more convenient.

Through the above structure, by dividing the support column equally, the load balance of the support column can be achieved, which is conducive to ensuring that each part is subjected to the same pressure, reducing the load of a single part, thereby reducing the possibility of deformation and stress concentration, improving the stability and safety of the structure, and being conducive to the relatively uniform wall thickness of the support column.

[0124] In the embodiment of the present application, both the movable disc 210 and the fixed disc 400 are made of ceramic. The use of ceramic components has excellent corrosion resistance and can be used stably for a long time in various acidic and alkaline environments, effectively resisting corrosion and extending the service life.

The feedback structure 238 and the sensing structure 221 on the control board 230 and the driven unit cooperate to output waterway status information including service status, salt absorption status, bypass status, backwash status, water replenishment status, slow wash status, and mixed water status. This structure is reasonable and achieves good water inlet performance.

[0127] 8 and 9 , in the present embodiment, an outer wall of the support structure 300 is spaced from an inner wall of the chamber 110 of the valve body 100 to form a water inlet gap. The water inlet gap is arranged around the support structure 300, and the water inlet gap is communicated with the water inlet cavity 310 of the support structure 300, and the water inlet gap is communicated with the water inlet groove 216 of the movable disc 210. The raw water reaches the water inlet gap through the water inlet channel 120, reaches the annular groove 215 through the multiple water inlet grooves 216 of the movable disc 210, and enters the water inlet cavity 310 through the annular groove 215. This not only disperses the water inlet pressure, but also compresses the movable disc 210 and the fixed disc 400 by water pressure.

[0128] 10 and 11 , in an embodiment of the present application, the movable disk 210 is further provided with a plurality of blind holes. The plurality of blind holes, the first opening 212 , the second opening 213 and the third opening 214 are arranged around the center line N of the movable disk 210 to improve the structural strength of the movable disk 210 . The layout is reasonable and the manufacturing is convenient, which is beneficial to reducing the weight and material of the movable disk 210 .

[0129] Regarding the center line N of the movable disk 210 , it can be understood that, in this embodiment, the outer contour of the movable disk 210 is circular, and the center line N of the movable disk 210 coincides with the center of the circular movable disk 210 .

[0130] Referring to Figures 2, 3 and 5, in an embodiment of the present application, the upper soft water valve also includes a blocking cover 600 and a valve cover 700.

The water outlet channel 130 and the tank outlet channel 150 are connected via the check valve 180 to allow one-way conduction from the tank outlet channel 150 to the water outlet channel 130 and prevent the liquid from flowing through the bypass chamber 350 to the tank outlet channel 150. The orthographic projections of the salt absorption channel 160 and the backwash chamber 340 overlap to facilitate the control of multiple water channels, making the design of the support structure 300 more reasonable and helping to reduce the volume of the soft water valve.

[0133] 14 to 21 , in this embodiment, the salt absorption and sewage discharge device 900 includes an ejector assembly 910, a check ball assembly 920 and a sewage discharge assembly 930.

One end of the check ball assembly 920 is connected to the other end of the ejector assembly 910. The other end of the check ball assembly 920 is connected and disconnected with the central tube 830 of the resin assembly 800. The sewage discharge assembly 930 is connected to the upper part of the resin tank for discharging wastewater.

[0134] The working process of the water softener in the embodiment of the present application is described below:

[0135] When the water softener is in service state, referring to FIG15, the first port 212, the fixed water outlet hole 420 and the water outlet chamber 320 are connected correspondingly, the second port 213, the second process hole 480 and the second process chamber 380 are connected correspondingly, the third port 214 is connected correspondingly to a part of the structure of the water inlet chamber 310, and the other part of the structure of the water inlet chamber 310 corresponds to the blind hole of the movable disk 210, wherein the remaining cavity positions and water holes are closed. Therefore, the raw water reaches the inlet through the water inlet channel 120. The water gap and the water inlet groove 216 reach the first port 212 through the multiple water inlet grooves 216 of the movable disc 210, reach the tank inlet channel 140 through the fixed water outlet hole 420 and the water outlet cavity 320, and then reach the lower part of the resin tank in the space where the resin body 840 is located outside the central tube 830 through the water channel component 810, the upper part of the resin tank and the resin body 840. After softening, it reaches the tank outlet channel 150 through the central tube 830 and reaches the water outlet channel 130 through the check valve 180.

[0136] When the water softener is in the salt absorption state, referring to Figure 16, a part of the structure of the first port 212 is connected to the fan-shaped groove of the fixed diverter hole 450 and the diverter cavity 360, and another part of the structure of the first port 212 is connected to the second process hole 480 and the second process cavity 380. The second port 213 and the third port 214 are both connected to the corresponding fixed water inlet hole 410 and the water inlet cavity 310. A part of the structure of the dynamic diverter groove 211 is connected to the fixed salt absorption hole 420 and the salt absorption cavity 330, and another part of the structure of the dynamic diverter groove 211 is connected to the fixed bypass hole 440 and the bypass cavity 350. The raw water enters the chamber 110 of the valve body 100 through the water inlet channel 120, and is filled with the water inlet cavity 310 and the diverter cavity 350 through the water inlet gap and the water inlet groove 216. Flow cavity 360, when the diversion cavity 360 of the support structure 300 is filled with raw water, the raw water is divided into two water paths through the dynamic diversion groove 211, one of which reaches the salt absorption cavity 330, and the other part of the raw water reaches the bypass cavity 350. The ejector assembly 910 generates negative pressure to suck in the salt water and mix the salt water and raw water into a mixed salt solution through the ejector assembly 910. At this time, the check ball assembly 920 is opened, and the salt water reaches the central pipe 830 through the ejector assembly 910 and the check ball assembly 920, and contacts the resin body 840 through the central pipe 830 and the lower part of the resin tank outside the central pipe 830 for regeneration. Finally, the waste water is discharged through the upper part of the resin tank and the sewage discharge assembly 930, and the raw water in the other bypass cavity 350 is discharged through the water outlet channel 130 to realize water supply during regeneration.

[0137] When the water softener is in the bypass state, referring to Figure 17, the first opening 212 and the second opening 213 are both connected to the fixed water inlet hole 410 and the water inlet chamber 310, and the third opening 214 is connected to the fixed bypass hole 440 and the bypass chamber 350. The remaining cavities and water holes are closed. The raw water enters the chamber 110 of the valve body 100, fills the water inlet chamber 310 and the water inlet gap, and reaches the bypass chamber 350 through multiple water inlet grooves 216 and the third opening 214, and is transported to the water outlet channel 130 through the bypass chamber 350 to realize water supply.

[0138] When the water softener is in the backwash state, referring to Figure 18, the first port 212 is connected to the fixed water inlet hole 410 and the water inlet chamber 310, the second port 213 is connected to the bypass chamber 350, and the third port 214 is connected to the fixed backwash hole 430 and the backwash chamber 340. The remaining cavities and water holes are closed, and the raw water enters the water inlet channel 120 and enters the chamber 110 of the valve body 100. It is divided into two paths of raw water through the water inlet gap and multiple water inlet grooves 216. One path of raw water enters the backwash chamber 340, enters the central tube 830 of the resin assembly 800 through the backwash channel 170, and contacts the bottom of the resin body 840 through the lower part of the resin tank outside the central tube 830 for backwashing. The other path of raw water reaches the bypass chamber 350 and flows out through the water outlet channel 130 to realize backwash water supply.

[0139] When the water softener is in the water replenishment state, as shown in Figure 19, a portion of the first port 212 and the salt absorption hole are correspondingly connected to the salt absorption chamber 330, the first port 212 and another portion of the structure are correspondingly connected to the backwash chamber 340, the second port 213 is correspondingly connected to the water outlet chamber 320, and the third port 214 is correspondingly connected to the second process chamber 380. Raw water enters the water inlet gap in the chamber 110 of the valve body 100 through the water inlet channel 120, reaches the first port 212 and the salt absorption chamber 330 through the water inlet groove 216 of the movable disk 210, and reaches the salt tank A through the ejector assembly 910 for water replenishment. The raw water reaching the water outlet chamber 320 can reach the upper part of the resin tank through the tank inlet channel 140, is softened by the resin body 840, and then reaches the central pipe 830 through the lower part of the resin tank. It then reaches the water outlet channel 130 through the tank outlet channel 150 and the check valve 180, achieving uninterrupted water supply. The remaining chambers and holes are closed. It should be noted that, in the water replenishment state, the check ball assembly 920 has a large water pressure on its upper part, so the ball of the check ball assembly 920 is in the position of closing the check ball assembly 920. Therefore, the water passing through the ejector assembly 910 will not reach the central tube 830 of the resin assembly 800, and the water passing through the salt absorption chamber 330 can only reach the salt box A.

[0140] When the water softener is in the slow washing state, referring to Figure 20, a part of the structure of the first opening 212 is connected to the fan-shaped groove of the fixed diversion hole 450 and the diversion chamber 360, and another part of the structure of the first opening 212 is connected to the second process hole 480 and the second process chamber 380. The second opening 213 and the third opening 214 are both connected to the corresponding fixed water inlet hole 410 and the water inlet chamber 310. A part of the structure of the dynamic diversion groove 211 is connected to the fixed salt absorption hole 420 and the salt absorption chamber 330. Another part of the structure of the dynamic diversion groove 211 is connected to the fixed bypass hole 440 and the bypass chamber 350. The remaining cavity positions and hole positions are closed. Raw water enters the chamber 110 of the valve body 100 through the water inlet channel 120, and then flows through the water inlet gap and the water inlet groove 216 to fill the water inlet chamber 310 and the diverter chamber 360. When the diverter chamber 360 of the support structure 300 is filled with raw water, the raw water is divided into two streams through the dynamic diverter groove 211. Since the ejector assembly 910 has absorbed all the brine and is disconnected from the brine tank A, one stream of raw water reaches the brine absorption chamber 330. The check ball assembly 920 opens, and the raw water flows through the ejector assembly 910 and the check ball assembly 920 to reach the central pipe 830. The raw water then contacts the resin body 840 through the central pipe 830 and the lower portion of the resin tank outside the central pipe 830 for slow washing. Finally, the waste water is discharged through the upper portion of the resin tank and the sewage discharge assembly 930. The raw water in the bypass chamber 350 is discharged through the water outlet channel 130, achieving uninterrupted water supply.

[0141] When the water softener is in a water mixing state, referring to FIG21 , during the water mixing process, the first opening 212 of the movable disk 210 and the fixed water outlet hole 420 and the water outlet cavity 320 of the fixed disk 400 are staggered at a preset angle to mix the water, and a portion of the fixed diverter hole 450 and the diverter cavity 360 is communicated with the first opening 212, a portion of the first opening 212 is correspondingly communicated with a portion of the fixed water outlet hole 420 and the water outlet cavity 320 of the fixed disk 400, another portion of the first opening 212 is correspondingly communicated with another portion of the second process hole 480 and the second process cavity 380 of the fixed disk 400, and a portion of the second opening 213 is correspondingly communicated with the second process hole 480 and the second process cavity 380 of the fixed disk 400. 80, the other part of the structure of the two is correspondingly connected, the other part of the structure of the second opening 213 is connected with a part of the structure of the fixed water inlet hole 410 and the water inlet chamber 310, and the third opening 214 is connected with a part of the structure of the fixed water inlet hole 410 and the water inlet chamber 310. After a part of the raw water reaches the chamber 110 of the valve body 100 through the water inlet channel 120, it reaches the water outlet chamber 320 through the water inlet gap and the water inlet groove 216, and reaches the area where the resin body 840 of the resin assembly 800 is located through the water outlet chamber 320 and the tank inlet channel 140, and reaches the check valve 180 after being softened. The other part of the raw water reaches the backwash chamber 340 and reaches the water outlet through the backwash channel 170, and the two parts of water are mixed.

[0142] 20 , in an embodiment of the present application, in the slow washing state, the channel between the salt box A and the ejector assembly 910 is closed, so that the resin body 840 is slowly flushed with the original mixed salt solution and the newly introduced raw water; in the mixed water state, the hardness of the soft water is adjusted.

[0143] 21 , in this embodiment, water mixing is performed according to the size of the water flow rate formed by the first opening 212 of the movable disc 210 and the fixed water outlet hole 420 and the water outlet cavity 320 of the fixed disc 400 being staggered at a preset angle. The angle between the first connecting line 232 and the sixth connecting line 237 is 35 degrees, that is, the set opening and closing angle formed by the service position and the water mixing limit position is 35 degrees. It can also be understood that after rotating the preset rotation angle of 35 degrees from the position corresponding to the service position to the position corresponding to the water mixing limit position, the water mixing ratio of the soft water valve is the largest, that is, the proportion of the unsoftened water flow in the mixed water is the largest. When the angle between the first connecting line 232 and the sixth connecting line 237 is less than 35 degrees, the water mixing ratio of the soft water valve is in a decreasing direction; when the angle between the first connecting line 232 and the sixth connecting line 237 is greater than 35 degrees, the soft water valve no longer mixes water.
