Referring to FIG. 1 , an embodiment of the present application provides a water softener. The water softener includes a water softening device 100 and a regeneration device 600 that are connected to each other. The water softener 100 contains functional ions (sodium ions). The functional ions can exchange with calcium and magnesium ions in the raw water, and absorb excess calcium and magnesium ions in the raw water, turning hard water into soft water. Usually, during the sodium ion exchange process, when the soft water becomes hard and the residual hardness exceeds the water quality standards, the sodium ions are considered to have expired. The regeneration device 600 can pass salt water (sodium chloride solution) into the water softening device 100. The salt water passes through the failed resin to replace the calcium and magnesium ions in the resin into the solution, thereby completing the regeneration of the sodium ions in the resin, so that the water softening device 100 Restore water softening function.

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.

In the soft water supply state, the raw water flows into the water softening device 100. The functional ions (sodium ions) contained in the softening device 100 exchange with the calcium and magnesium ions in the raw water, and adsorb the excess calcium and magnesium ions in the water, turning the hard water into soft water. And discharged for use by users. 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, but when it is not in the soft water supply state, the water softener can supply raw water to ensure that the water softener is in the soft water supply state and the non-soft water supply state. There is water flowing out of the water softener to avoid the water softener cutting off and causing a bad experience to the user.

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 turned on and the raw water supply channel is cut off. The water softening device 100 is connected to the raw water source through the soft water supply channel, and the raw water flows to the softening device 100 through the soft water supply channel. Functional ions (sodium ions) contained in the water softening device 100 exchange with calcium and magnesium ions in the raw water, and adsorb excess calcium and magnesium ions in the water, turning hard water into soft water, and then discharged through the soft water supply channel for user use. Since the raw water supply channel is cut off, the water softener cannot supply raw water when supplying soft water.

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 opened. When the water softener no longer supplies soft water, the water softener can supply raw water, ensuring that the water softener continues to flow and improving user experience.

The water softening device 100 includes a resin tank 200, an upper water distributor 300, a central pipe 500 and a lower water distributor 400. The resin tank 200 includes a tank body and a resin containing functional ions in the tank body. The upper water distributor 300 and the upper end of the central pipe 500 are connected to the regeneration device 600 . The lower water distributor 400 is connected to the lower end of the central pipe 500 . When the water softener is in the soft water supply state, the raw water first flows through the soft water supply channel 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 and the functional ions on the resin After exchange, soft water is formed and flows to the central pipe 500 through the lower water distributor 400. The soft water flowing out from the central pipe 500 then flows out through the soft water supply channel on the regeneration device 600 for use by users.

In one embodiment, the non-soft water supply state includes a regeneration state. In the regeneration state, the regeneration device 600 can pass salt water (sodium chloride solution) into the water softening device 100, and the salt water passes through the failed resin to remove calcium and magnesium ions therein. It is replaced into the solution to complete the regeneration of sodium ions in the resin and restore the water softening function of the water softening device 100 .

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 first brine with a first concentration to the water softener 100, and the first brine passes through the failed resin to convert it into Calcium and magnesium ions are replaced into the solution to complete the regeneration of sodium ions in the resin. In the second regeneration state, the regeneration device 600 provides the second salt water with the second concentration to the water softening device 100, and replaces the calcium and magnesium ions in the failed resin into the solution, thereby completing the regeneration of sodium ions in the resin. Wherein, the first concentration and the second concentration are different.

In the water softener provided by the present application, in the first regeneration state and the second regeneration state, the concentrations of the first salt water and the second salt water flowing into the water softening device 100 are different. That is, the water softener provided by the present application can sequentially supply water to the water softener. The water softening device 100 passes two different concentrations of salt water. Compared with the prior art regeneration device 600 that can only pass one concentration of salt water into the water softening device 100, the combination of two different concentrations of salt water can improve the quality of the water softener. When the regeneration rate of functional ions is increased, the amount of soft water produced by the water softener can be increased accordingly.

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 through the central pipe 500 to the lower water distributor 400, and are sprayed into the resin tank through the lower water distributor 400. 200 resin, the brine passes through the failed resin to replace the calcium and magnesium ions in the resin into the solution. The replaced solution flows into the upper water distributor 300 and enters the regeneration device 600 from the upper water distributor 300 for discharge.

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 pipe 500, and the first regeneration channel provides the first salt water to the water softener 100. At this time, the second regeneration channel is cut off. When the water softener is in the second regeneration state, the second regeneration channel is connected to the central pipe 500, and the second regeneration channel provides the second salt water to the water softening device 100. At this time, the first regeneration channel is cut off. It should be understood that in other embodiments, the regeneration device 600 can also be provided with only one regeneration channel. When the first salt water needs to be introduced, the first salt water is introduced to the water softening device 100 through the first regeneration channel. When adding the second salt water, just pass the second salt water into the water softening device 100 through the second regeneration channel.

The regeneration device 600 also has a forward wash channel and a backwash channel. The water softener also has a forward washing state and a backwashing state. When the water softener is in the forward washing state, the forward washing channel is turned on, and the raw water cleans the water softening device 100 from top to bottom through the forward washing 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 pipe 500. In this state, the raw water flows through the resin layer in the resin tank 200 from top to bottom. Pressure slowly precipitates the fluffy resin, exchanges ions, and precipitates dirt at the same time. When the water softener is in the backwashing state, the backwash channel is turned on, and the raw water passes through the backwash channel from top to bottom to clean the water softener 100 . That is, the raw water flows to the lower water distributor 400 through the central pipe 500, 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, fluffing the resin to achieve the purpose of powerful flushing (ion exchange).

The regeneration device 600 includes a salt supply device 700 and an integrated water channel 800 . The integrated water channel 800 is provided between the salt supply device 700 and the water softening device 100 . Saturated brine is stored in the salt supply device 700. The soft water supply channel, raw water supply channel, first regeneration channel, second regeneration channel, forward washing channel and backwash channel are all located on the integrated water channel 800 and are connected to the raw water source. When the water softener is in the soft water supply state, the soft water supply channel is turned on, 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. The softened water softened by the water softening device 100 can flow out through the soft water supply channel for use by users. When the water softener is in the first regeneration state, the first 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 first regeneration channel to form the first brine, and the first brine is mixed through the first regeneration channel. The first brine is supplied to the water softening device 100 . 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 a second brine, and the second brine is mixed through the second regeneration channel. The second brine is supplied to the water softening device 100 .

Referring to Figures 2 and 3, the first regeneration channel includes a first water conduction channel 11, a first salt conduction channel and a first mixing channel. One end of the first water conduction channel 11, the first salt conduction channel and the first mixing channel is at The first intersection is connected, the other end of the first water conduction channel away from the first intersection is connected with the raw water source, the other end of the first salt conduction channel away from the first intersection is connected with the salt supply device 700, and the first mixing channel is away from the first intersection. The other end of a junction is connected to the water softening device 100 . The cross-sectional area of the first water conducting channel 11 gradually decreases from the other end far away from the first intersection to the end close to the first intersection.

In this way, when the raw water flows through the first water guide channel 11, since the cross-sectional area of the first water guide channel 11 is gradually reduced from the other end away from the first intersection to the end close to the first intersection, then when the raw water flows from the first water guide channel 11 to the first water guide channel 11, the cross-sectional area of the first water guide channel 11 is gradually reduced. When a water guide channel 11 flows from an end far away from the first mixing channel to an end close to the first mixing channel, the flow rate of the raw water gradually increases, forming a first negative pressure. Under the action of the first negative pressure, the salt supply device 700 The saturated brine in the water flows into the first mixing channel through the first salt conduction channel, the raw water and the saturated brine are mixed in the first mixing channel to form the first salt water of the first concentration, and the first salt water flows into the soft water device 100 through the first mixing channel .

Referring to Figure 4, the second regeneration channel includes a second water conduction channel 12, a second salt conduction channel and a second mixing channel. The second water conduction channel 12, the second salt conduction channel and the second mixing channel are connected at the second intersection. , the other end of the second water conduction channel 12 away from the second intersection is connected to the raw water source, the other end of the second salt conduction 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 salt supply device. One end is connected to the second channel. The cross-sectional area of the second water conduit channel 12 gradually decreases from the other end far away from the second intersection to the end close to the second intersection.

In this way, when the raw water flows through the second water conduction channel 12, since the cross-sectional area of the second water conduction channel 12 is gradually reduced from the other end far away from the second intersection to the end close to the second intersection, then when the raw water flows from the second water conduction channel 12 to the second water conduction channel 12, the cross-sectional area gradually decreases. When the second water guide channel 12 flows from the end far away from the second mixing channel to the end close to the second mixing channel, the flow rate of the raw water gradually increases, forming a second negative pressure. Under the action of the second negative pressure, the salt supply device 700 The saturated brine in the water flows into the second mixing channel through the second salt conduction channel, the raw water and the saturated brine are mixed in the second mixing channel to form a second salt water with a second concentration, and the second brine flows into the water softening device 100 through the second mixing channel. .

Furthermore, the lengths of the first water guide channel 11 and the second water guide channel 12 are equal. The end of the first water guide channel 11 away from the first intersection is the same as the cross section of the end of the second water guide channel 12 away from the second intersection. The cross-sectional areas of the end of the first water conduit channel 11 close to the first intersection and the end of the second water conduit channel 12 close to the second intersection are equal. In this way, ensuring that the first negative pressure and the second negative pressure are not equal, it is ensured that the first concentration of the finally formed first salt water and the second concentration of the second salt water are not equal.

It should be understood that in other embodiments, other setting methods can be used to realize that the first concentration and the second concentration are not equal, which is not limited here.

In a specific embodiment, the cross-sectional area of the end of the first water guide channel 11 close to the first intersection is larger than the cross-sectional area of the end of the second water guide channel 12 close to the second intersection, so that the first negative pressure is smaller than the first negative pressure. Two negative pressures, at this time, more saturated brine flows from the first salt conducting channel to the first mixing channel, while less saturated brine flows from the second salt conducting channel to the second mixing channel, so the first concentration is smaller than the second concentration.

Continuing to refer to FIG. 1 , the integrated waterway 800 includes an ejector 10 and a multi-way valve 900 . The ejector 10 is disposed between the multi-way valve 900 and the salt supply device 700 . The first water conducting channel 11 , the first salt conducting channel, the second water conducting channel 12 , the second salt conducting channel, the first mixing channel and the second mixing channel are all provided on the ejector 10 .

When the water softener is in a slow washing state, the regeneration device 600 provides raw water to the water softening device 100 for slow washing. Specifically, the speed at which the regeneration device 600 provides raw water to the water softener 100 is smaller 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, when the water softener enters the first regeneration state, it switches to the slow washing state. At this time, the regeneration device 600 can provide slower raw water to the water softening device 100. When the water softener enters the second regeneration state, it switches to the slow washing state. , at this time, the regeneration device 600 can provide slower raw water to the water softening device 100 .

In the channel 219, the water flows from the latent channel 219 to the water outlet J, and then flows to the water softening device 100 through the water outlet J for slow washing. In this way, it is avoided to install additional pipelines for slow cleaning of the water softening device 100, and the structure of the water softener is simplified.

In one embodiment, a groove 2163 is provided on the first flow control plane 2161 of the fixed valve plate 216 (see Figure 14).

In another embodiment, a groove 2163 is formed on the surface of the valve body 215 facing the fixed valve plate 216 . 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, grooves 2163 are formed on the surfaces of the fixed valve plate 216 and the valve body 215 facing each other, and the groove walls of the two grooves 2163 form a latent channel 219 .

The water inlet and the fourth port D are the same port 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 both ends of the latent channel 219. In this way, when the latent channel 219 extends along 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 the slow washing state, the water guide channel connects the water outlet J and the second sub-port C2, so that the raw water flows from the water outlet J to the second sub-port C2 and flows into the water softening device 100 through the third channel 23. to flush the resin layer from bottom to top.

Define the connection line between the water inlet and the center point of the fixed valve plate 216 as the first connection line, the connection line between the water outlet J and the center point of the fixed valve plate 216 as the second connection line, the first connection line and the second connection line The angle formed between them 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 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 do not interfere with each other. .

There is a distance between the center point of the guide groove 311 and the moving valve plate 31, so that the position of the guide groove 311 on the moving valve plate 31 corresponds to the position of the above-mentioned ports on the fixed valve plate 216, thereby facilitating flow guidance. The groove 311 communicates with two of the plurality of ports. Continuing to refer to FIG. 10 , the guide groove 311 includes a first guide part 3111 , a second guide part 3112 and a third guide part 3113 that are connected in sequence in the circumferential direction of the sheet body 313 .

In the radial direction of the moving valve plate 31 , the blocking portion 316 is located on one side of the second flow guide portion 3112 . With this arrangement, when the guide groove 311 communicates with two ports, the blocking 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.

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 the second sub-port C2 or the second port. B is conductive, and prevents the water outlet J from being conductive with the second sub-port C2 or the second port B. When the guide groove 311 communicates with 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 communicating with the second sub-port C2 or the water outlet J.

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

The outer contour of the guide groove 311 is located in a virtual sector. At this time, 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 flow. Slot 311 communicates with the remaining ports between the two ports. Of course, in other embodiments, the shape of the guide groove 311 is not limited.

In the radial direction of the moving valve plate 31, the cut-off portion 314 extends from the outer peripheral edge of the plate body 313 where the guide groove 311 is provided. Specifically, the extension length of the cut-off portion 314 in the circumferential direction of the moving valve plate 31 is greater than the first guide groove. The extension length of the portion 3111 in the circumferential direction of the moving valve plate 31 is such that when the first flow guide portion 3111 communicates with the seventh port G, the cutting portion 314 can cover the portion where the seventh port G communicates with the communication cavity 40, thereby avoiding When supplying soft water, mix it with raw water.

The working principle of the water softener provided by the embodiment of this application is as follows:

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 ports connected to the inlet water tank 312 on the fixed valve plate 216 are different, and the ports connected to the guide groove 311 are different, then The multi-way valve 900 is switched between the soft water supply station, the first regeneration station, the second regeneration station, the forward washing station, the backwashing station, the slow washing station and the salt supply device water replenishing station, correspondingly , so that the water softener switches 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.

In order to facilitate the explanation of each state, the seventh port G is defined to include a first part G1 and a second part G2 connected to each other in the radial direction (see Figure 23). The second part G2 is far away from the center of the fixed valve plate 216 relative to the first part G1. Designed on point.

In the soft water supply state (see Figure 24):

The water inlet 312 communicates with the eighth port H, the guide groove 311 communicates with the second sub-port C2 and the first part G1 of the seventh port G, and the cutting part 314 covers the second part G2 of the seventh port G.

The raw water flows through the sixth channel 210, the connecting cavity 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 on the resin. After functional ion exchange, soft water is formed and flows to the central pipe 500 through the lower water distributor 400.

The replaced wastewater flows upward to the water distributor 300, and water is distributed from above. The container 300 flows to the eighth channel 214, the drainage groove 315, the conduction cavity 50 and the ninth channel 218 and is discharged in sequence.

Specifically, after the first regeneration state, the water softener is in the slow washing state, and after the second regeneration state, the water softener is in another slow washing state. That is, after each regeneration state, the water softener is switched to the slow washing state. In this way, the resin layer can be slowly washed from bottom to top, taking away the broken resin and remaining dirt, and improving the utilization rate of the salt solution. 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, but not to perform slow washing after the second regeneration state.
