[0057] Water softeners utilize ion exchange, exchanging sodium ions in the resin for calcium and magnesium ions in the water. This absorbs excess calcium and magnesium ions and removes scale. Water softeners utilize a multi-way valve with a flow control component. These components coordinate with each other to switch between various flow paths, enabling switching between operating modes such as water supply, backwash, regeneration, forward wash, and water replenishment. However, the flow control components in existing multi-way valves are complex in structure, making switching between diversion channels inconvenient.

[0058] Based on the above considerations, the inventors designed a water softener, a multi-way valve and a flow control component thereof, which have a simple and reasonable structural design and convenient flow channel switching.

[0059] Please refer to Figure 1 In one embodiment, the flow control component 11 includes a fixed valve disc 100, a movable valve disc 200 and a driving member (not shown). The driving member is transmission-connected to the movable valve disc 200 and drives the movable valve disc 200 to rotate relative to the fixed valve disc 100 so that the movable valve disc 200 cooperates with the fixed valve disc 100 at different working positions.

[0060] Among them, combined with reference Figures 2 to 5 The fixed valve plate 100 has at least six through holes, and the movable valve plate 200 has at least three grooves; when the movable valve plate 200 switches to different working positions, the grooves of the movable valve plate 200 can match and connect the corresponding through holes of the fixed valve plate 100 to form different diversion channels.

[0061] Through the above arrangement, the flow channel is switched by the rotational cooperation between the movable valve disc 200 and the fixed valve disc 100 , the adjustment is flexible and convenient, and the structural design is reasonable.

[0062] In a specific embodiment, the driving member is a motor or a cylinder. The workstations can be arranged sequentially, that is, the driving member drives the movable valve disc 200 to rotate in the same direction to switch to the aforementioned workstations in sequence. The workstations can also be arranged in a non-sequential manner, that is, the driving member drives the movable valve disc 200 to rotate in different directions to switch to the aforementioned workstations in sequence.

[0063] Specifically, refer to Figures 2 to 5 The fixed valve disc 100 has a first through hole 110 , a third through hole 130 , a fourth through hole 140 , a sixth through hole 160 , a seventh through hole 170 and an eighth through hole 180 , and the movable valve disc 200 has a guide groove 210 , a water inlet groove 220 and a drainage groove 230 .

[0064] like Figure 7 As shown, when the movable valve plate 200 is located at the first regeneration position, the water inlet groove 220 is connected to the third through hole 130, the guide groove 210 is connected to the sixth through hole 160 and the seventh through hole 170, and the drain groove 230 is connected to the first through hole 110; Figure 8 As shown, when the movable valve plate 200 is located at the second regeneration position, the water inlet groove 220 is connected to the fourth through hole 140, the guide groove 210 is connected to the sixth through hole 160 and the eighth through hole 180, and the drainage groove 230 is connected to the first through hole 110; Figure 9 As shown, when the movable valve plate 200 is located at the forward washing position, the water inlet groove 220 is connected to the first through hole 110, and the water outlet groove 230 is connected to the sixth through hole 160; Figure 10 As shown, when the movable valve plate 200 is located at the water replenishing position, the water inlet groove 220 is connected to the eighth through hole 180.

[0065] It is understood that when the movable valve disc 200 is located in the first regeneration station, a saline solution of a first concentration flushes the resin in the resin tank 40 from bottom to top, and the sodium ions in the saline solution exchange ions with the calcium and magnesium ions in the resin, thereby achieving the purpose of resin regeneration; when the movable valve disc 200 is located in the second regeneration station, a saline solution of a second concentration flushes the resin in the resin tank 40 from bottom to top, thereby achieving the purpose of resin regeneration through ion exchange; when the movable valve disc 200 is located in the forward washing station, raw water flows through the resin in the resin tank 40 from top to bottom, and the fluffy resin is slowly precipitated and ion-exchanged by water pressure to precipitate the dirt in the resin; when the movable valve disc 200 is located in the water replenishment station, raw water is injected into the salt supply device 30 to ensure that sufficient saline solution is stored in the salt supply device 30. It should be noted here that the saline concentrations used in the first regeneration station and the second regeneration station are not equal, that is, the first concentration is not equal to the second concentration. Specifically, the first concentration is greater than the second concentration.

[0066] For example, a high-concentration regeneration liquid is first supplied to the water softener. This high-concentration regeneration liquid enters the softener's resin tank through a multi-way valve and undergoes sufficient ion exchange with the resin in the tank. As regeneration progresses, the number of ions that need to be exchanged decreases. At this time, the regeneration flow is switched and a low-concentration regeneration liquid is supplied to the water softener. This low-concentration regeneration liquid enters the softener's resin tank through a multi-way valve. Providing a low-concentration regeneration liquid at this stage does not waste salt or hinder the regeneration effect, and is more conducive to improving the utilization rate of the salt solution and the regeneration rate.

[0067] Through the above arrangement, the flow channel is switched by the rotational cooperation of the movable valve plate 200 and the fixed valve plate 100, the adjustment is flexible and convenient, and the structural design is reasonable; by setting two regeneration stations, it is beneficial to improve the utilization rate of the salt solution and reduce salt consumption.

[0068] For further information, please refer to Figure 2 , the fixed valve plate 100 also has a second through hole 120. Figure 11 When the movable valve plate 200 rotates to the backwash position, the water inlet groove 220 is connected to the second through hole 120, and the water outlet groove 230 is connected to the first through hole 110.

[0069] In this way, when the movable valve plate 200 is located at the backwashing station, the resin in the resin tank 40 is flushed from bottom to top by raw water, so as to strongly flush the resin and make the resin fluffy.

[0070] For further information, please refer to Figure 2 , the fixed valve plate 100 also has a fifth through hole 150. Figure 12 When the movable valve plate 200 is located at the water supply position, the water inlet groove 220 is connected to the first through hole 110 , and the guide groove 210 is connected to the fifth through hole 150 and the sixth through hole 160 .

[0071] In this way, when the movable valve plate 200 is located at the water supply position, the water softener softens the raw water and outputs soft water.

[0072] like Figure 2 and Figure 3 In the illustrated embodiment, the first through hole 110 , the second through hole 120 , the third through hole 130 , the fourth through hole 140 , the fifth through hole 150 , the sixth through hole 160 , the seventh through hole 170 and the eighth through hole 180 are arranged in sequence along the circumference of the fixed valve plate 100 .

[0073] With this arrangement, the through holes are spaced apart on the fixed valve plate 100 , which can meet the needs of flow channel switching under different workstations. At the same time, the fixed valve plate 100 has a compact structure, which helps to reduce the overall space occupancy of the flow control component 11 .

[0074] In a specific embodiment, the spacing between the first through hole 110, the second through hole 120, the third through hole 130, the fourth through hole 140, the fifth through hole 150, the sixth through hole 160, the seventh through hole 170 and the eighth through hole 180 is designed according to actual needs and is not specifically limited here.

[0075] In this embodiment, please refer to Figure 2 , the opening areas of the sixth through hole 160 , the first through hole 110 and the fifth through hole 150 decrease in sequence.

[0076] It is understood that the sixth through-hole 160 corresponds to the center pipe 70, the fifth through-hole 150 corresponds to the outlet pipe, and the first through-hole 110 corresponds to the first water distributor 50. When the movable valve plate 200 is in the water supply position, raw water enters the multi-way valve 10 through the water inlet pipe and flows sequentially through the first through-hole 110, the first water distributor 50, the center pipe 70, the second water distributor 60, the fifth through-hole 150, and the sixth through-hole 160 to the outlet pipe, where soft water is output. Through this arrangement, the flow rate of the flow control assembly 11 in the multi-way valve 10 is changed by controlling the opening size of each through-hole, thereby stabilizing the flow rate and facilitating smooth soft water output.

[0077] In other embodiments, the opening areas of the sixth through hole 160 , the fifth through hole 150 , and the first through hole 110 may be equal.

[0078] In this embodiment, if Figure 2 As shown, the first through hole 110, the fifth through hole 150, and the sixth through hole 160 are all fan-shaped. In other embodiments, the first through hole 110, the fifth through hole 150, and the sixth through hole 160 can all be bar-shaped, or the first through hole 110, the second through hole 120, the third through hole 130, the fourth through hole 140, the fifth through hole 150, the sixth through hole 160, the seventh through hole 170, and the eighth through hole 180 can each have a different shape.

[0079] In this embodiment, Figure 2 As shown, the third through hole 130 and the fourth through hole 140 are both located on one side of the line connecting the second through hole 120 and the sixth through hole 160 , and the seventh through hole 170 and the eighth through hole 180 are both located on the other side of the line connecting the second through hole 120 and the sixth through hole 160 .

[0080] It can be understood that the third through hole 130 corresponds to the first jet inlet of the ejector 20, the fourth through hole 140 corresponds to the second jet inlet of the ejector 20, the seventh through hole 170 corresponds to the first jet outlet of the ejector 20, the eighth through hole 180 corresponds to the second jet outlet of the ejector 20, and the second through hole 120 and the sixth through hole 160 both correspond to the central tube 70. Through the above arrangement, the two through holes corresponding to the two jet inlets and the other two through holes corresponding to the two jet outlets are respectively located on different sides of the line connecting the second through hole 120 and the sixth through hole 160, thereby improving the space utilization of the fixed valve plate 100 and making the structure of the fixed valve plate 100 more compact.

[0081] In this embodiment, if Figure 2 As shown, the sixth through hole 160 is fan-shaped, and the second through hole 120, the third through hole 130, the fourth through hole 140, the seventh through hole 170, and the eighth through hole 180 are all strip-shaped, so as to make the arrangement of the through holes more compact while meeting the size settings of each through hole. In other embodiments, the second through hole 120, the third through hole 130, the fourth through hole 140, the sixth through hole 160, the seventh through hole 170, and the eighth through hole 180 can also all be fan-shaped or strip-shaped, or the second through hole 120, the third through hole 130, the fourth through hole 140, the seventh through hole 170, and the eighth through hole 180 can each have a different shape.

[0082] In a specific embodiment, the opening sizes of the second through hole 120 , the third through hole 130 , the fourth through hole 140 , the sixth through hole 160 , the seventh through hole 170 , and the eighth through hole 180 may be equal or unequal.

[0083] like Figure 2 and Figure 3 In the illustrated embodiment, the fixed valve plate 100 is further provided with a ninth through hole 190 and a slow wash channel 191 . The ninth through hole 190 is located between the seventh through hole 170 and the eighth through hole 180 . The ninth through hole 190 and the third through hole 130 are connected via the slow wash channel 191 .

[0084] In this embodiment, reference Figure 13 When the movable valve plate 200 is located at the slow wash station, the guide groove 210 is connected to the ninth through hole 190 and the sixth through hole 160, and the drainage groove 230 is connected to the first through hole 110. This arrangement can meet the requirement of the flow channel under the slow wash station, and the structural design is reasonable.

[0085] Understandably, the reference Figure 13 When the movable valve plate 200 is in the slow-wash position, raw water flows into the resin tank 40 through the water inlet pipe, then flows through the third through-hole 130, the slow-wash channel 191, the ninth through-hole 190, the diversion groove 210, the sixth through-hole 160, the center pipe 70, the second water distributor 60, the first water distributor 50, the first through-hole 110, the drainage groove 230, and finally exits through the wastewater pipe. In other words, raw water is introduced into the resin tank 40 and slowly rinses the resin therein from bottom to top, ultimately discharging the crushed resin and any remaining dirt.

[0086] In this embodiment, if Figure 3 As shown, the ninth through hole 190 is in a bar shape. In other embodiments, the ninth through hole 190 may also be in a circular shape or other shapes.

[0087] In this embodiment, if Figure 3 As shown, the slow wash channel 191 is in a strip shape. In other embodiments, the slow wash channel 191 can also be in a wavy shape or other shapes.

[0088] In this embodiment, Figure 2 As shown, the fixed valve disc 100 is provided with a avoidance hole 192, which runs through the outer edge of the fixed valve disc 100 and communicates with the outside. Through this arrangement, the avoidance hole 192 of the fixed valve disc 100 can be communicated with the water inlet 12i of the valve body 12, so as to facilitate water inlet to the valve body 12.

[0089] like Figure 2 In the embodiment shown, the fixed valve plate 100 has a first flow control surface 101 and a second flow control surface 102 arranged relatively to each other, the first through hole 110, the second through hole 120, the third through hole 130, the fourth through hole 140, the fifth through hole 150, the sixth through hole 160, the seventh through hole 170, the eighth through hole 180 and the ninth through hole 190 pass through the first flow control surface 101 to the second flow control surface 102, and the slow wash channel 191 is arranged on the second flow control surface 102.

[0090] Through this arrangement, on the basis of ensuring that the flow channels of all workstations are connected, the space utilization of the fixed valve plate 100 is improved, and the structure of the fixed valve plate 100 is made more compact.

[0091] In this embodiment, the fixed valve disc 100 is circular. In other embodiments, the fixed valve disc 100 can also be rectangular or other shapes.

[0092] like Figure 4 In the illustrated embodiment, the movable valve disc 200 has a third flow control surface 201 and a fourth flow control surface 202 that are oppositely disposed. The movable valve disc 200 covers the fixed valve disc 100 , and the fourth flow control surface 202 abuts against the first flow control surface 101 .

[0093] In this embodiment, Figure 4As shown, the water inlet groove 220, the flow guide groove 210, and the drainage groove 230 are recessed from the fourth flow control surface 202 toward the third flow control surface 201 and are evenly spaced along the circumference. This arrangement improves the space utilization of the movable valve plate 200 while ensuring flow continuity at all workstations, making the structure of the movable valve plate 200 more compact.

[0094] In a specific embodiment, the spacing and size between the water inlet groove 220, the guide groove 210 and the drainage groove 230 are designed according to actual needs and are not specifically limited here.

[0095] In this embodiment, if Figure 4 As shown, the movable valve plate 200 is circular. In other embodiments, the movable valve plate 200 can also be rectangular or other shapes.
