Description

Technical Field

[0001] This invention relates to the field of water treatment technology, and in particular to a multi-way valve, a fixed valve plate, and a water softener. Background Technology

[0002] Currently, tap water used in cities is usually sourced from groundwater. However, groundwater typically contains calcium and magnesium ions, which can easily cause scale buildup during use, leading to damage to electrical appliances. Softening hard water can effectively prevent kidney stones, reduce the burden on the heart and kidneys, and benefit people's health. It also prevents electrical appliances from being damaged by excessive scale buildup. Therefore, water softeners, which can soften hard water, are being used more and more frequently in daily life.

[0003] Water softeners typically work by exchanging functional ions on resin with calcium and magnesium ions in the water, thereby adsorbing excess calcium and magnesium ions and removing limescale. Current water softeners generally include an integrated water circuit and a softening device and a brine supply device connected to it. Raw water enters the softening device through the integrated water circuit, where the resin layer softens the raw water and outputs it to the user through the integrated water circuit. When all the resin is saturated with calcium and magnesium ions, the water softener can no longer soften tap water, requiring backwashing and regeneration of the exchange resin. The brine supply device, after dissolving and saturating with salt, enters the softening device. The saturated salt solution soaks the resin, causing the numerous sodium ions in the solution to replace the calcium and magnesium ions adsorbed on the resin. Once the calcium and magnesium ions are replaced, the resin achieves regeneration, preparing it for the next water softening cycle.

[0004] In existing water softeners, the multi-way valve is the core component for controlling the flow direction of water in the integrated water circuit. By controlling the multi-way valve to switch between different work positions, the water flow can be controlled to flow in different directions in different structures, thereby realizing functions such as water supply, backwashing, regeneration, and water replenishment. Therefore, the wastewater generated from cleaning the resin and the raw water to be softened are both collected in the multi-way valve.

[0005] However, in integrated water circuits, the multiple flow paths within a multi-way valve need to be connected and assembled with the flow paths in the water softener and brine supply devices. The existing multi-way valve structure is not reasonable, resulting in an unreasonable assembly position and spatial distribution of the water softener or brine supply device inside the water softener. Therefore, it is necessary to design a multi-way valve with a reasonable structure to facilitate better connection and assembly with other devices in the water softener. Summary of the Invention

[0006] This invention addresses the problem of unreasonable multi-way valve structure by providing a multi-way valve, a fixed valve plate, and a water softener. This multi-way valve, fixed valve plate, and water softener can achieve the technical effect of reasonable water circuit structure and uniform internal space distribution in the water softener.

[0007] According to one aspect of the present invention, a multi-way valve is provided, having a valve chamber capable of communicating with a water softener or an ejector; characterized in that the multi-way valve comprises:

[0017] In one embodiment, the fourth connecting hole can be connected to the water softening device through the valve chamber; and / or, the fourth connecting hole can be connected to the outlet of the multi-way valve.

[0018] In one embodiment, the fourth connecting hole is disposed between the first central hole and the second connecting hole; and / or, is disposed between the first central hole and the third connecting hole.

[0019] In one embodiment, the first central hole and the fourth connecting hole are arranged in a ring shape extending circumferentially along the valve body.

[0021] The first connecting hole is located on the center line, and along the direction intersecting the center line, the second connecting hole and the third connecting hole are arranged on both sides of the center line.

[0022] In one embodiment, the second connecting hole is connected to the third connecting hole to form at least two flow channels with different flow areas.

[0045] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0046] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this invention.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0051] like Figure 1 As shown, an embodiment of the present invention provides a water softener 100, which can remove calcium and magnesium ions from raw water through ion exchange resin, thereby reducing water hardness and providing soft water with lower calcium and magnesium ion content for water-using equipment.

[0052] As described in the background section, and see also... Figure 1 and Figure 2The water softener 100 includes an integrated water circuit and a water softening device 40 and a brine supply device connected to the integrated water circuit. The integrated water circuit includes a multi-way valve 20 for controlling the direction of water flow. The water softening device 40 includes a resin tank 41, an upper water distributor 45, a lower water distributor 47, and a central pipe 43. The resin tank 41 is filled with a resin layer formed of resin particles. The central pipe 43 is vertically inserted into the resin tank 41. The upper water distributor 45 and the lower water distributor 47 are respectively installed at both ends of the central pipe 43. The upper ends of the upper water distributor 45 and the central pipe 43 are connected to the multi-way valve 20, while the lower water distributor 47 is inserted into the resin layer. The salt supply device includes an ejector 60 and a salt tank 80. The multi-way valve 20 is connected to the salt tank 80 through the ejector 60. The ejector 60 includes a water inlet and / or a water outlet connected to the multi-way valve 20. That is, the raw water in the multi-way valve 20 can enter the ejector 60 through the water inlet, and the regenerated liquid generated in the ejector 60 can flow into the multi-way valve 20 through the water outlet.

[0053] Furthermore, the ejector 60 includes a first water inlet, a first water outlet, a second water inlet, and a second water outlet, which are respectively connected to the multi-way valve 20. The raw water in the multi-way valve 20 can enter the ejector 60 through the first water inlet and the second water inlet, and the regenerated liquid generated in the ejector 60 can flow into the multi-way valve 20 through the first water outlet or the second water outlet.

[0054] The multi-way valve 20 has seven positions: water supply position, backwash position, first regeneration position, slow wash position, second regeneration position, water replenishment position, and forward wash position. The multi-way valve 20 can switch between the above positions so that the water softener 100 has seven states: water supply state, backwash state, first regeneration state, slow wash state, second regeneration state, water replenishment state, and forward wash state.

[0055] like Figure 2 and Figure 3 As shown, when the water softener 100 is in the water supply state, the multi-way valve 20 is in the water supply position. The raw water enters the resin layer in the resin tank 41 through the upper water distributor 45 from the multi-way valve 20. The calcium and magnesium ions in the raw water exchange with the sodium ions on the resin layer to soften the water. The softened water generated enters the central pipe 43 through the lower water distributor 47 and finally flows out through the multi-way valve 20 to supply water to water-using equipment.

[0056] like Figure 4 As shown, when the water softener 100 is in backwash mode, the multi-way valve 20 is in the backwash position. Raw water can pass through the multi-way valve 20 sequentially through the central pipe 43 and the lower water distributor 47, and then flush the resin layer in the resin tank 41 from bottom to top. The wastewater after cleaning is discharged through the upper water distributor 45 and then through the multi-way valve 20. At this time, if the user is using water at the terminal simultaneously, raw water can also flow out through the multi-way valve 20 to directly supply raw water to the user.

[0057] like Figure 5As shown, when the water softener 100 is in the first regeneration state, the multi-way valve 20 is in the first regeneration position. Raw water can flow into the first water inlet of the ejector 60 through the multi-way valve 20. Due to the negative pressure, the brine in the brine tank 80 is drawn out and mixed with the raw water to form a regenerated solution of the first concentration. The brine solution flows out from the first water outlet of the ejector 60, and passes through the multi-way valve 20, the central pipe 43, and the lower water distributor 47 in sequence into the resin layer in the resin tank 41. After the brine solution mixes with the resin layer and replaces the sodium and magnesium ions on the resin layer, it is discharged through the upper water distributor 45 and then through the multi-way valve 20. At this time, if the user is using water at the terminal simultaneously, raw water can also flow out through the multi-way valve 20 to directly supply raw water to the user.

[0058] like Figure 6 As shown, when the water softener 100 is in slow wash mode, the multi-way valve 20 is in the slow wash position. Raw water flows from the multi-way valve 20 through the central pipe 43 and the lower water distributor 47, slowly rinsing the resin layer in the resin tank 41 from bottom to top. The wastewater after rinsing is discharged through the upper water distributor 45 and then through the multi-way valve 20. If the user is simultaneously using water at the terminal, raw water can also flow out through the multi-way valve 20, directly supplying raw water to the user.

[0059] like Figure 7 As shown, when the water softener 100 is in the second regeneration state, the multi-way valve 20 is in the second regeneration position. Raw water can flow into the second water inlet of the ejector 60 through the multi-way valve 20. Due to the negative pressure, the brine in the brine tank 80 is drawn out and mixed with the raw water to form a regenerated solution of the second concentration. The brine solution flows out from the second water outlet of the ejector 60, and passes through the multi-way valve 20, the central pipe 43, and the lower water distributor 47 in sequence into the resin layer in the resin tank 41. After the brine solution mixes with the resin layer and replaces the sodium and magnesium ions on the resin layer, it is discharged through the upper water distributor 45 and then through the multi-way valve 20. At this time, if the user is using water at the terminal simultaneously, raw water can also flow out through the multi-way valve 20 to directly supply raw water to the user.

[0060] like Figure 8 As shown, when the water softener 100 is in the water replenishment state, the multi-way valve 20 is in the water replenishment position. Raw water flows from the multi-way valve 20 into the ejector 60 and then into the brine tank 80 to replenish the brine tank 80. At this time, if the user is using water at the terminal simultaneously, raw water can also flow out through the multi-way valve 20 to directly supply raw water to the user.

[0061] like Figure 9 As shown, when the water softener 100 is in the forward washing state, the multi-way valve 20 is in the forward washing position. Raw water can enter the resin layer in the resin tank 41 through the multi-way valve 20 via the upper water distributor 45. The water pressure slowly settles the loose resin and precipitates out the dirt. The wastewater after washing passes through the lower water distributor 47 and the central pipe 43 and is discharged through the multi-way valve 20. At this time, if the user uses water at the terminal simultaneously, raw water can also flow out through the multi-way valve 20 to directly supply raw water to the user.

[0062] Please see Figures 10 to 12 The multi-way valve 20, which has the aforementioned seven working positions, specifically includes a valve cavity 25 and a valve body 21. The valve cavity 25 can communicate with the water softener 40 or the ejector 60. The valve body 21 has a first connecting hole 221, a second connecting hole 222, and a third connecting hole 223. The valve cavity 25 is connected to the water softener 40 through the first connecting hole 221, and the valve cavity 25 is connected to the ejector 60 through the second connecting hole 222 and / or the third connecting hole 223. Thus, the multi-way valve 20 is connected to the water softener 40 through the first connecting hole 221, and the multi-way valve 20 is connected to the ejector 60 through the second connecting hole 222 and / or the third connecting hole 223.

[0063] Furthermore, the first connecting hole 221 is located on the center line, see reference. Figure 2 Along the direction intersecting the centerline, the second connecting hole 222 and the third connecting hole 223 are arranged on both sides of the centerline. In this way, the different inlets or outlets of the ejector 60 that connect with the second connecting hole 222 and the third connecting hole 223 are located on both sides of the valve body 21, so as not to cause insufficient assembly space or the ejector 60 being assembled on one side while the other side is empty, thus providing a multi-way valve 20 with a more reasonable structural layout.

[0064] In one embodiment, see [reference] Figure 10 and Figure 11 The valve body 21 includes a seat 211 and a valve core assembly 22. The multi-way valve 20 also includes a valve stem 23 and a valve core nut 24. The seat 211 has a hollow shell structure and a receiving cavity with one end communicating with the external environment. The receiving cavity has a bottom wall and a side wall. The side wall surrounds the bottom wall circumferentially to form an opening communicating with the external environment. The valve core assembly 22 is housed within the receiving cavity of the seat 211.

[0065] Furthermore, the valve core assembly 22 includes a fixed valve plate 225 and a movable valve plate 226. The fixed valve plate 225 is fixedly installed in the receiving cavity and abuts against the bottom wall of the receiving cavity. The movable valve plate 226 is stacked on the side of the fixed valve plate 225 away from the bottom wall of the receiving cavity. The first axial end of the valve stem 23 extends into the receiving cavity and is drivenly engaged with the movable valve plate 226. The second axial end of the valve stem 23 extends out of the receiving cavity to engage with the drive unit. The valve core nut 24 is sleeved on the second axial end of the valve stem 23 and housed in the receiving cavity. The valve core nut 24 is used to close the opening of the receiving cavity to form a sealed space, and at the same time, it can apply pressure to the valve core assembly 22 to form an end face seal between the movable valve plate 226 and the fixed valve plate 225. Driven by the drive unit, the valve stem 23 drives the movable valve plate 226 to rotate relative to the fixed valve plate 225, thereby switching the multi-way valve 20 between different working positions.

[0066] Furthermore, the valve core assembly 22 and the seat 211 together form the valve cavity 25. It is understood that the first connecting hole 221, the second connecting hole 222, and the third connecting hole 223 may be formed on at least one of the fixed valve plate 225 or the moving valve plate 226. See also... Figure 12 The first connecting hole 221, the second connecting hole 222, and the third connecting hole 223 are formed on the fixed valve plate 225. In other embodiments, the first connecting hole 221, the second connecting hole 222, and the third connecting hole 223 may also be formed directly on the seat 211. The present invention is not limited herein.

[0067] In one specific embodiment, the first connecting hole 221 includes a first central hole a and a second central hole b. The first central hole a and / or the second central hole b can be connected to the soft water device 40 through the valve cavity 25. The line connecting the first central hole a and the second central hole b forms a center line, so that the different inlets or outlets of the jet injector 60 that are connected to the second connecting hole 222 and the third connecting hole 223 are located on both sides of the valve body 21, saving space and not affecting the water flow in the central pipe 43. While achieving a compact structure for the multi-way valve 20, it can ensure sufficient flow in the integrated water circuit.

[0068] Understandably, the first central hole a and the second central hole b are set as two ports for connecting the soft water device 40. When the multi-way valve 20 is in different positions, the first central hole a and / or the second central hole b are connected according to the actual function.

[0069] In one embodiment, when the first central hole a and / or the second central hole b are connected to the central pipe 43 of the water softening device 40, different channels for water flow can be formed in the central pipe 43 of the water softening device 40 to meet the functional requirements of the water softening device 40 in different states.

[0070] In one embodiment, the valve chamber 25 is connected through a second connecting hole 222 and a third connecting hole 223, forming at least two flow channels. Specifically, the flow areas of the multiple flow channels can be different. The second connecting hole 222 can have multiple openings, and the third connecting hole 223 can also have multiple openings. The different openings are interconnected to form multiple flow channels with different flow areas. Flow channels with different flow areas can provide regenerant of different concentrations to regenerate the soft water device 40 to different degrees. The multiple flow channels formed by the connection between the second connecting hole 222 and the third connecting hole 223 can correspond to the water inlet or water outlet of the ejector 60, respectively. That is, if the second connecting hole 222 and the third connecting hole 223 are connected to form two flow channels, the ejector 60 has two water inlets and / or two water outlets. If the second connecting hole 222 and the third connecting hole 223 are connected to form three flow channels, the ejector 60 has three water inlets and / or three water outlets, and so on. These are not listed here.

[0071] Furthermore, the second connecting hole 222 includes a second water inlet hole c and a third water inlet hole d spaced apart on one side of the center line, and the third connecting hole 223 includes a second water outlet hole e and a third water outlet hole f spaced apart on the other side of the center line.

[0072] In some embodiments, the second connecting hole 222 may also have multiple water inlets such as a fourth water inlet and a fifth water inlet, and the third connecting hole 223 may have multiple water outlets such as a fourth water outlet and a fifth water outlet. These are not listed here.

[0073] The valve chamber 25 is connected to the jet ejector 60 through the second water inlet hole c and the second water outlet hole e to form a first flow channel. The valve chamber 25 is connected to the jet ejector 60 through the third water inlet hole d and the third water outlet hole f to form a second flow channel. The flow areas of the first flow channel and the second flow channel are different.

[0074] Furthermore, the raw water in the multi-way valve 20 can enter the ejector 60 through the second inlet port c and mix with the saturated brine to generate a regenerated solution of the first concentration, and then flow out from the second outlet port e. Alternatively, the raw water in the multi-way valve 20 can also enter the ejector 60 through the third inlet port d and mix with the saturated brine to generate a regenerated solution of the second concentration, and then flow out from the third outlet port f.

[0075] Furthermore, through the above arrangement, the water inlet side and water outlet side of the jet injector 60 are respectively arranged on both sides of the connection port of the central pipe 43 (i.e., the first connecting hole 221), which realizes the partitioned installation through function, making the structural arrangement uniform and reasonable.

[0076] In one embodiment, the valve body 21 also has a fourth communication hole 224, which can be connected to the soft water device 40 through the valve cavity 25; and / or, the fourth communication hole 224 can be connected to the outlet of the multi-way valve 20.

[0077] In one embodiment, the fourth connecting hole 224 includes a fourth water inlet hole g, which is located between the first central hole (a) and the second connecting hole (222) or between the first central hole (a) and the third connecting hole (223). The fourth water inlet hole g can be connected to the soft water device 40 through the valve chamber 25.

[0078] In another embodiment, the fourth connecting hole 224 includes a fourth water inlet hole g and a fourth water outlet hole h, which are located on both sides of the center line formed by the line connecting the first central hole a and the second central hole b of the first connecting hole 221. More specifically, the fourth water inlet hole g is located between the second central hole b and the third connecting hole 223, and the fourth water outlet hole h is located between the first central hole a and the second connecting hole 222; or the fourth water inlet hole g is located between the first central hole a and the second connecting hole 222, and the fourth water outlet hole h is located between the second central hole b and the third connecting hole 223. The fourth water inlet hole g is connected to the upper water distributor 45 of the soft water device 40, and the fourth water outlet hole h is directly connected to the water-using end.

[0079] like Figure 13 and Figure 14 As shown, the movable valve plate 226 has multiple connecting slots, and multiple connecting holes are interconnected through the connecting slots on the movable valve plate 226. Specifically, the movable valve plate 226 has a first connecting slot 2262, a second connecting slot 2264, and a third connecting slot 2266 on the side surface of the movable valve plate 225. The first connecting slot 2262, the second connecting slot 2264, and the third connecting slot 2266 are arranged sequentially at intervals along the circumference of the movable valve plate 226. Among them, the first connecting slot 2262 is fan-shaped, extending along the circumference of the movable valve plate 226, and the outer edge of the first connecting slot 2262 connects to the outer periphery of the movable valve plate 226. The second connecting slot 2264 is elongated, with the edge of the movable valve plate 226 extending radially to the center of the movable valve plate 226. It penetrates through the center point to the side end face of the movable valve plate 226 away from the fixed valve plate 225, that is, the center of the movable valve plate 226 is penetrated to form a through hole 2268. The third connecting groove 2266 is shaped like a "door" with its opening facing the edge of the moving valve plate 226.

[0080] In one embodiment, the first central hole a and the fourth connecting hole 224 are arranged in a ring extending circumferentially along the valve body 21. Under the action of the driving unit, each connecting groove on the moving valve plate 226 can match each through hole on the fixed valve plate 225.

[0081] Specifically, when the multi-way valve 20 is in the water supply position, the first connecting groove 2262 of the moving valve plate 226 connects the inlet of the multi-way valve 20 and the fourth inlet hole g of the fourth connecting hole 224; the third connecting groove 2266 of the moving valve plate 226 connects the first central hole a of the first connecting hole 221 and the fourth outlet hole h of the fourth connecting hole 224. Raw water can enter the upper water distributor 45 from the fourth inlet hole g of the fourth connecting hole 224, and then enter the resin layer in the resin tank 41. After the calcium and magnesium ions in the raw water exchange with the sodium ions on the resin layer to soften the water, the softened water generated enters the central pipe 43 through the lower water distributor 47 and then flows from the first central hole a, through the third connecting groove 2266 into the fourth outlet hole h, and flows out from the fourth outlet hole h to supply the water-using equipment.

[0082] Specifically, when the multi-way valve 20 is in the backwash position, the first connecting groove 2262 of the moving valve plate 226 connects the inlet of the multi-way valve 20 with the second central hole b; the second connecting groove 2264 connects with the fourth inlet g; and the inlet of the multi-way valve 20 connects with the fourth outlet h. Raw water can flow from the second central hole b through the central pipe 43 and the lower distributor 47, flushing the resin layer in the resin tank 41 from bottom to top. The cleaned wastewater is discharged through the upper distributor 45 from the fourth inlet g through the second connecting groove 2264. If the user uses water at the terminal at this time, raw water can also flow from the inlet of the multi-way valve 20 into the fourth outlet h, and the raw water flowing out from the fourth outlet h is directly supplied to the user.

[0083] Specifically, when the multi-way valve 20 is in the first regeneration position, the first connecting groove 2262 connects the inlet of the multi-way valve 20 to the second inlet hole c; the second connecting groove 2264 connects to the fourth inlet hole g; the third connecting groove 2266 connects the first central hole a to the second outlet hole e; and the inlet of the multi-way valve 20 connects to the fourth outlet hole h. Raw water can enter the ejector 60 through the second inlet hole c of the multi-way valve 20 via the first water inlet. Due to the negative pressure, the brine in the brine tank 80 is drawn out and mixed with the raw water to form a regenerated solution of the first concentration. The brine solution flows from the first water outlet to the second outlet hole e of the multi-way valve 20, and then sequentially passes through the third connecting groove 2264, enters the first central hole a, the central pipe 43, and the lower water distributor 47 into the resin layer in the resin tank 41. After the brine solution mixes with the resin layer and replaces the sodium and magnesium ions on the resin layer, it is discharged through the upper water distributor 45 from the fourth inlet hole g and the second connecting groove 2264. If the user uses water at the terminal at this time, the raw water can also flow from the inlet of the multi-way valve 20 into the fourth outlet hole h, and the raw water flowing out from the fourth outlet hole h can be directly supplied to the user.

[0084] Specifically, when the multi-way valve 20 is in the slow washing position, the first connecting groove 2262 connects the inlet of the multi-way valve 20 to the second inlet hole c; the second connecting groove 2264 connects to the fourth inlet hole g; the third connecting groove 2266 connects the third outlet hole f to the first central hole a; and the inlet of the multi-way valve 20 connects to the fourth outlet hole h. Raw water can enter the lower water distributor 47 from the second inlet hole c of the multi-way valve 20 sequentially through the third outlet hole f, the third connecting groove 2266, the first central hole a, and the central pipe 43. The raw water enters the resin tank 41 and slowly rinses the resin layer from bottom to top. The wastewater after rinsing is discharged through the upper water distributor 45, the fourth inlet hole g, and the second connecting groove 2264. If the user uses water at the terminal at this time, the raw water can also flow from the inlet of the multi-way valve 20 into the fourth outlet hole h, and the raw water flowing out from the fourth outlet hole h is directly supplied to the user.

[0085] Specifically, when the multi-way valve 20 is in the second regeneration position, the first connecting groove 2262 connects the inlet of the multi-way valve 20 to the third inlet hole d; the second connecting groove 2264 connects to the fourth inlet hole g; the third connecting groove 2266 connects to the third outlet hole f and the first central hole a; and the inlet of the multi-way valve 20 connects to the fourth outlet hole h. Raw water can enter the ejector 60 through the third inlet hole d of the multi-way valve 20 via the second water inlet. Due to the negative pressure, the brine in the brine tank 80 is drawn out and mixed with the raw water to form a regenerated solution of the second concentration. The brine solution flows from the second water outlet to the third outlet hole f of the multi-way valve 20, and sequentially passes through the first central hole a, the third connecting groove 2266, the central pipe 43, and the lower water distributor 47 into the resin layer in the resin tank 41. After the brine solution mixes with the resin layer and replaces the sodium and magnesium ions on the resin layer, it is discharged through the upper water distributor 45 from the fourth inlet hole g and the second connecting groove 2264. If the user uses water at the terminal at this time, the raw water can also flow from the inlet of the multi-way valve 20 into the fourth outlet hole h, and the raw water flowing out from the fourth outlet hole h can be directly supplied to the user.

[0086] Specifically, when the water softener 100 is in the water replenishment state, the multi-way valve 20 is in the water replenishment position, the first connecting groove 2262 connects the passage between the inlet of the multi-way valve 20 and the third outlet hole f; the inlet of the multi-way valve 20 is connected to the fourth outlet hole h.

[0087] Raw water flows into the ejector 60 through the third outlet hole f of the multi-way valve 20 and then into the brine tank 80 to replenish the brine tank 80. If the user uses water at the terminal at this time, the raw water can also flow into the fourth outlet hole h from the inlet of the multi-way valve 20, and the raw water flowing out from the fourth outlet hole h is directly supplied to the user.

[0088] Specifically, when the multi-way valve 20 is in the positive washing position, the first connecting channel 2262 connects the inlet of the multi-way valve 20 to the fourth inlet hole g; the second connecting channel 2264 connects to the first central hole a; and the third connecting channel 2266 connects to the fourth outlet hole h. Raw water can enter the resin layer in the resin tank 41 from the fourth inlet hole g through the upper water distributor 45. The water pressure slowly settles the loose resin and precipitates out the dirt. The wastewater after washing passes through the lower water distributor 47, the central pipe 43, and the first central hole a in sequence, and is discharged through the second connecting channel 2264. If the user uses water at the terminal at this time, the raw water can also flow from the inlet of the multi-way valve 20 into the fourth outlet hole h, and the raw water flowing out from the fourth outlet hole h is directly supplied to the user.

[0089] According to another aspect of the present invention, a multi-way valve 20 and a fixed valve plate 225 as described in the above embodiment are provided, wherein the second connecting hole 222 and the third connecting hole 223 are arranged on both sides of the center line intersecting the center line of the first connecting hole 221. This allows the different inlets or outlets of the ejector 60 that connect to the second connecting hole 222 and / or the third connecting hole 223 to be located on both sides of the valve body 21, avoiding insufficient assembly space or overcrowding on one side, thus providing a multi-way valve 20 and a fixed valve plate 225 with a more rational structural layout.

[0090] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0091] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
