The water softener usually exchanges calcium and magnesium ions in water through functional ions on resin, so that redundant calcium and magnesium ions in water are adsorbed, and the aim of removing scale is fulfilled. The water softener among the prior art generally includes integrated water route and connects water softener and the confession salt device on integrated water route, and during the raw water got into water softener through integrated water route, the resin layer among the water softener can soften the raw water and export the soft water through integrated water route and supply the user to use. When all the resins are fully adsorbed with calcium and magnesium ions, the water softener can not soften tap water any more, and at the moment, backwashing regeneration is needed to be carried out on the exchange resins. After the salt in the salt supply device is dissolved and saturated by the injected water, the saturated salt solution soaks the resin, so that a large number of sodium ions in the saturated salt solution replace calcium and magnesium ions adsorbed on the resin. When calcium and magnesium ions are replaced, the resin achieves the effect of reduction and regeneration, and preparation is made for the next water softening work.

In the existing water softener, the multi-way valve is used as a core component for controlling the flow direction of water in the integrated water channel, and water flow can be controlled to flow in different directions in different structures by controlling the multi-way valve to be switched in different stations, so that the functions of water supply, backwashing, regeneration, water supplement and the like are realized.

Referring to fig. 1, fig. 1 shows an internal structure of a multi-way valve 100 according to an embodiment of the present disclosure. An embodiment of the present application provides a water softener (not shown) that includes a water softener that removes calcium and magnesium ions from raw water through an ion exchange resin, thereby reducing water hardness to provide soft water with a low content of calcium and magnesium ions to a user. As described in the background art, the water softener includes an integrated waterway in which a multi-way valve 100 for controlling the flow direction of water is disposed, and a water softening device and a salt supply device connected to the integrated waterway, and the multi-way valve 100 generally has five stations of water supply, backwashing, regeneration, water supplement, and normal washing.

When the multi-way valve 100 is located at the water supply station, the water softener can perform softening treatment on raw water to provide qualified soft water for users to use. When the multi-way valve 100 is positioned at the backwashing station, the raw water washes the resin layer from bottom to top in the water softening device to enable the resin layer to be fluffy so as to achieve the purpose of strong washing. When the multi-way valve 100 is in the regeneration station, the brine in the brine supply device flows through the resin layer in the water softening device from bottom to top, so that the purposes of cleaning and ion exchange are achieved. When the multi-way valve 100 is positioned at the water replenishing station, raw water enters the salt supplying device to replenish water for the salt supplying device. When the multi-way valve 100 is positioned at the forward washing station, raw water flows through the resin layer of the water softening device from top to bottom, the fluffy resin layer is slowly precipitated under the action of water pressure, and dirt is separated out while ions are exchanged.

The multi-way valve 100 having only five stations can provide only a high concentration of the regenerating salt, and thus the regeneration rate of the resin is low, resulting in a small water yield of the water softener. Moreover, the water softener lacks a slow washing function, and the soft water treatment process is rough. In order to improve the regeneration rate of resin and optimize the soft water treatment process, the multi-way valve 100 of the application is additionally provided with a regeneration station and a slow washing station on the basis of five stations of water supply, backwashing, regeneration, water replenishing and forward washing, and the two regeneration stations can provide two different regenerated salt concentrations, so that the resin regeneration rate is improved. The slow washing station can enable raw water to slowly wash the resin layer from bottom to top, and take away broken resin and residual dirt, so that the utilization rate of salt solution is improved.

Utility model people discover in the research process, on the one hand, when multiport valve 100 is in the water supply station, the soft water process of water softener generally required time is longer, carries out the in-process that raw water softened the processing at the water softener, if the user has the water demand, then the water softener can't satisfy. On the other hand, when the multi-way valve 100 is located at a non-water supply station (such as backwashing, regeneration, slow washing, water replenishing and normal washing), raw water enters the water softener or the salt supply device, and at this time, if a user needs water, the water softener cannot meet the requirement. Accordingly, in order to provide a water softener that can continuously supply water, the present application provides a multi-way valve 100 that can achieve a flow-uninterrupted state, and can supply soft water after the generation of the soft water and supply raw water when the soft water cannot be supplied.

In some embodiments, the multiplex valve 100 includes a valve body 20, a spool assembly 60, and a valve stem 40. Specifically, the valve body 20 is a hollow shell structure, and the valve body 20 is provided with a valve cavity 21 with an opening at one end. The valve core assembly 60 is accommodated in the valve cavity 21 of the valve body 20, the first axial end of the valve rod 40 extends into the valve cavity 21 and is in transmission fit with the valve core assembly 60, and the second axial end of the valve rod 40 extends out of the valve cavity 21 and is in fit with the driving unit. In this way, under the driving of the driving unit, the valve rod 40 can drive the valve core assembly 60 to switch in different states, so as to change the working positions of the multi-way valve 100 to realize different functions.

Referring to fig. 2 to 6, the valve core assembly 60 includes a fixed valve plate 61 and a movable valve plate 63, and the fixed valve plate 61 is fixedly installed in the valve cavity 21 and located at the bottom of the valve cavity 21. Above the fixed valve with the movable valve plate 63 stacked, the first axial end of the valve rod 40 is connected with the movable valve plate 63 in a transmission manner, and the movable valve plate 63 is driven by the driving unit to rotate relative to the fixed valve plate 61.

The movable valve plate 63 has a first position and a second position relative to the fixed valve plate 61, and when the fixed valve plate 61 is at the first position, the multi-way valve 100 is at a non-water supply station, namely a backwashing station, a regeneration station, a slow washing station, a water replenishing station or a forward washing station. When the fixed valve plate 61 is in the second position, the multi-way valve 100 is in the water supply position. It will be appreciated that the first position is not a fixed position, but a range of positions in which the multi-way valve 100 cannot supply soft water.

The fixed valve plate 61 has a first through hole 612 penetrating along the thickness direction thereof, the movable valve plate 63 includes a main body 631 and a first blocking portion 632 protruding from the outer periphery of the main body 631, the main body 631 has a first end surface 6311 and a second end surface (not shown) opposite to each other in the thickness direction (i.e., the direction perpendicular to the bottom of the valve chamber 21), and the fixed valve plate 61 is attached to one side of the first end surface 6311 of the main body. Further, the outer peripheral edge of the main body 631 is configured to form a raw water flow path YS, and the raw water flow path YS and the outer peripheral edge of the first blocking portion 632 together surround to form a closed circumference.

Thus, in the process that the movable valve plate 63 rotates relative to the fixed valve plate 61, the raw water flow passage YS can communicate with the first communication hole 612, thereby realizing raw water supply. Alternatively, in the process that the movable valve plate 63 rotates relative to the fixed valve plate 61, the raw water flow path YS and the first communication hole 612 are blocked by the first blocking part 632, and at this time, the first communication hole 612 is used to supply soft water, and the first blocking part 632 blocks the raw water flow path YS and the first communication hole 612, so that the raw water is prevented from flowing into the first communication hole 612 and mixing with the soft water. In this manner, the user may use the demineralized water while the multiport valve 100 is in the service position. When the multi-way valve 100 is in a non-water supply station, a user can use raw water, and the raw water and soft water share the same water outlet, namely the first communication hole 612, so that long-time waiting or multi-tap installation is not needed, and the multi-way valve is quick and convenient.

Specifically, the fixed valve plate 61 has a disk-shaped structure, the main body 631 has a disk-shaped configuration similar to the fixed valve plate 61, and the first blocking portion 632 extends along the circumferential direction of the main body 631. When the movable valve plate 63 is at the first position, the main body 631 covers a portion of the first communication hole 612, and a projection of the first blocking portion 632 on the fixed valve plate 61 is staggered from the first communication hole 612. At this time, the remaining portion of the first communication hole 612, which is not covered by the body 631, communicates with the raw water flow path YS, and the raw water may directly flow to the first communication hole 612 after entering the multi-way valve 100. When the movable valve plate 63 is at the second position, the main body 631 covers part of the first communication hole 612, and the first blocking part 632 covers the remaining part of the first communication hole 612, so that the first communication hole 612 is completely covered, and at this time, the raw water flow channel YS and the first communication hole 612 are separated by the first blocking part 632, and the raw water cannot enter the first communication hole 612.

In one embodiment, the main body 631 further has a guide groove 6312, and in a radial direction of the movable valve plate 63, the first blocking portion 632 is located on one side of the guide groove 6312, and at least a portion of the guide groove 6312 is located in a sector area surrounded by the first blocking portion 632 and a center of the main body 631. The fixed valve plate 61 is provided with a second communication hole 614, when the movable valve plate 63 rotates to the second position relative to the fixed valve plate 61, the raw water flow passage YS and the first communication hole 612 are blocked, at this time, the second communication hole 614 is communicated with the first communication hole 612 through the guide groove 6312, at this time, the soft water flows from the second communication hole 614 to the first communication hole 612, and thus, the soft water supply is realized.

In one embodiment, the fixed valve plate 61 further has a plurality of third communication holes 616 formed therethrough, when the movable valve plate 63 rotates to the first position relative to the fixed valve plate 61, the raw water flow channel YS communicates with the first communication hole 612, and at this time, the second communication hole 614 communicates with any one of the third communication holes 616 alternatively through the diversion groove 6312, so that the multi-way valve 100 having the valve core assembly 60 is switched among a plurality of different water supply stations.

Specifically, the first communication hole 612, the second communication hole 614, and the plurality of third communication holes 616 are arranged at intervals in the circumferential direction of the stationary plate 61, and the plurality of third communication holes 616 are located on the same side as the second communication hole 614. Specifically, in one embodiment, the second communication hole 614 is disposed in a ring shape extending along the circumferential direction of the stationary plate 61.

In this embodiment, the fixed valve plate 61 is provided with three third communication holes 616, the three third communication holes 616 are all located on the same side of the second communication hole 614, and each third communication hole 616 is circular or oval. It is understood that the number and shape of the third communication holes 616 are not limited, and may be set as required to meet different requirements.

In one embodiment, the flow guide groove 6312 includes a first flow guide part 63121, a second flow guide part 63123 and a third flow guide part 63125 which are sequentially connected. The first flow guide part 63121 and the third flow guide part 63125 are disposed at intervals in the circumferential direction of the movable valve plate 63, the second flow guide part 63123 extends lengthwise in the circumferential direction of the movable valve plate 63, the two opposite ends of the second flow guide part 63123 in the circumferential direction of the movable valve plate 63 are respectively connected to the first flow guide part 63121 and the second flow guide part 63123, a second blocking part 633 is formed between the first flow guide part 63121 and the third flow guide part 63125, and in the radial direction of the movable valve plate 63, the second blocking part 633 is located on one side of the second flow guide part 63123 close to the first blocking part 632.

When the movable valve plate 63 and the fixed valve plate 61 are attached to each other and located at the second position, an orthographic projection of the first blocking portion 632 on the fixed valve plate 61 coincides with the first communicating hole 612 to block the raw water flow channel YS and the first communicating hole 612, at this time, an orthographic projection of the first flow guide portion 63121 on the fixed valve plate 61 coincides with the first communicating hole 612 to communicate with the first communicating hole 612, and an orthographic projection of the third flow guide portion 63125 on the fixed valve plate 61 coincides with the second communicating hole 614 to communicate with the second communicating hole 614. The first and third guides 63121 and 63125 communicate through the second guide 63123 such that the first and second communication holes 612 and 614 communicate.

When the movable valve plate 63 and the fixed valve plate 61 are attached to each other and located at the first position, the projection of the first blocking portion 632 on the fixed valve plate 61 is staggered from the first communication hole 612 to communicate the raw water flow channel YS with the first communication hole 612, at this time, the orthographic projection of the first flow guide portion 63121 on the fixed valve plate 61 is overlapped with the second communication hole 614 to communicate the second communication hole 614, and the orthographic projection of the third flow guide portion 63125 on the fixed valve plate 61 can be alternatively overlapped with one third communication hole 616 to communicate the third communication hole 616. An orthographic projection of the second dam 633 on the stationary plate 61 may coincide with one of the third communication holes 616 for covering the remaining third communication holes 616 between the second communication hole and the third communication hole communicated through the guide groove 6312.

In this way, the diversion trench 6312 of the movable valve plate 63 forms a "door" structure, and the first blocking portion 632 is disposed at the top of the "door" structure. When the first blocking portion 632 does not perform the blocking function, the raw water flows to the first communication hole 612 through the raw water flow path YS, the water in one of the third communication holes 616 of the fixed valve sheet 61 may sequentially flow into the second communication hole 614 through the third flow guide portion 63125, the second flow guide portion 63123 and the first flow guide portion 63121, and the remaining third communication holes 616 between the mutually communicated third communication holes 616 and the second communication holes 614 are closed by the second blocking portion 633. When the first blocking portion 632 performs a blocking function, the raw water flow path YS and the first communication hole 612 are blocked, and at this time, the liquid in the second communication hole 614 of the fixed valve plate 61 sequentially passes through the third flow guide portion 63125, the second flow guide portion 63123, and the first flow guide portion 63121 and flows into the first communication hole 612.

Therefore, the water softener with the movable valve plate 63 can obtain raw water through the first communication hole 612 in a non-water supply state and obtain soft water through the first communication hole 612 in a water supply state, so that the water softener can continuously supply water in a multifunctional state, and a user can use water in any state of the water softener.

In an embodiment, the second diversion part 63123 is located on a side of the second blocking part 633 far from the first blocking part 632, so that while the first diversion part 63121 and the third diversion part 63125 are communicated, a projection of the second diversion part 63123 on the fixed valve sheet 61 is disposed to be offset from the third communication hole 616, and the second diversion part 63123 only serves to communicate the first diversion part 63121 and the second diversion part 63123, without causing the third communication hole 616 which does not need to be communicated to be in a conducting state.

As a preferred embodiment, in order to match the arrangement of the second communication hole 614 and the third communication hole 616, the outer contour of the diversion trench 6312 is located in a virtual sector, and the virtual sector extends along the circumferential direction of the movable valve plate 63. It is understood that the shape and size of the diversion trench 6312 are not limited thereto, and may be configured as needed to meet different requirements.
