Description

Technical Field

[0001] This utility model relates to the field of water softener technology, and in particular to a water distributor and a water softener. Background Technology

[0002] Currently, most water softeners on the market operate in five modes: softening, backwashing, slow brine flushing, forward flushing, and water replenishment. The slow brine flushing mode primarily involves drawing brine into the tank to provide sufficient sodium ions to the resin, replacing the calcium and magnesium ions adsorbed on the resin and restoring its ion exchange capacity. It also washes away the displaced calcium and magnesium ions and other impurities, ensuring effective softening after resin regeneration. To ensure more even distribution of the brine on the resin, a distributor is installed on the brine inlet pipe.

[0003] Currently, most water softeners on the market use a long, conical water distributor structure. However, this structure has certain problems. Because the brine entering the distributor is vertically downwards, while in a long, conical distributor, the outlets are distributed around the perimeter, the incoming brine first impacts the bottom wall of the distributor, creating severe eddies within the internal cavity and affecting the distributor's distribution efficiency.

[0004] Due to the large inertial effect, the brine mainly flows out from the upper outlet of the conical water distributor, while the utilization rate of the lower outlet is low. This results in a small and uneven diffusion range of the brine, which cannot cover the resin particles near the bottom of the water distributor, thus affecting the softening and regeneration of the resin particles. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defect of existing water distributors that are difficult to cover the resin at the bottom of the water distributor, thus affecting the softening and regeneration of resin particles, and to provide a water distributor and a water softener.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] This utility model provides a water distributor, which has a flow guiding cavity inside and a connecting part for connecting to a pipe at one end;

[0008] The water distributor has an inner groove recessed towards the flow guide cavity at one end away from the connection part. The inner groove includes an inner sidewall, and the inner sidewall has a plurality of inner water outlet holes penetrating the inner sidewall.

[0009] In this design, the water distributor has a flow guiding chamber, and one end of the distributor has a connecting part for connecting to a pipe. Saltwater enters the flow guiding chamber from the connecting part. An inner groove is provided at the end of the water distributor away from the connecting part, pointing towards the flow guiding chamber. Multiple internal water outlet holes are provided on the inner wall of the inner groove, allowing water in the flow guiding chamber to flow out through these holes and cover the resin at the bottom of the water distributor. This ensures the resin at the bottom can fully contact the saltwater, improving the softening effect of the resin particles.

[0010] Preferably, in the direction from near the connection portion to away from the connection portion, the inner sidewall extends radially outward from the radially inner side of the water distributor.

[0011] In this solution, in the direction from near the connection to away from the connection, by setting the inner sidewall to extend radially outward from the radially inner side of the water distributor, it is possible to buffer the vertical downward impact of brine and reduce brine collision. The outwardly extending inner sidewall can guide the water flow, so that the water flow direction can be inclined outward, reducing the generation of eddies.

[0012] Preferably, the water distributor further includes an outer peripheral wall, which has a plurality of water outlet holes penetrating the outer peripheral wall;

[0013] In the direction from the connection portion toward the distance from the connection portion, the outer peripheral wall extends radially inward from the radially outer side of the water distributor.

[0014] In this design, the outer peripheral wall of the water distributor is provided with multiple outlet water holes that penetrate the outer peripheral wall. The brine in the guide cavity can flow out to the resin on the outside through the outlet water holes. In the direction from near the connection part to away from the connection part, by extending the outer peripheral wall from the radially outer side to the radially inner side of the water distributor, the impact of the water flow on the outer peripheral wall can be reduced. It can also guide the water flow that climbs the wall, so that the water flow flows to the outside and reduces the generation of eddies.

[0015] Preferably, the outer peripheral wall comprises a first part and a second part in sequence along the axial direction of the water distributor, wherein the first part is located at the end of the second part away from the connecting part and is connected to the second part;

[0016] The inner diameter of the second part is larger than the inner diameter of the first part.

[0017] In this design, by setting the inner diameter of the second part to be larger than that of the first part, the inner side of the outer peripheral wall becomes stepped, which further reduces the impact of water flow on the outer peripheral wall and reduces the generation of eddies.

[0018] Preferably, the water distributor includes an outer guide member and an inner guide member, the outer guide member covering the inner guide member, and the outer guide member and the inner guide member forming the guide cavity;

[0019] The inner guide includes an outer peripheral wall, and the outer peripheral wall is provided with a plurality of outflow holes penetrating the outer peripheral wall;

[0020] The external guide includes a first guide portion, the lower end of which extends to the outer peripheral side of the outer peripheral wall, and a gap is provided between the inner peripheral surface of the first guide portion and the outer peripheral surface of the outer peripheral wall.

[0021] In this design, the outer guide member covers the inner guide member, and the outer and inner guide members form a guide cavity. The outer guide member includes a first guide section, the lower end of which extends to the outer peripheral side of the outer peripheral wall. A gap is provided between the inner peripheral surface of the first guide section and the outer peripheral surface of the outer peripheral wall. Thus, when the brine in the guide cavity flows out from the outlet water hole, the water flows into the gap between the inner peripheral surface of the first guide section and the outer peripheral surface of the outer peripheral wall. The first guide section can guide the outflowing brine downward, reduce the generation of eddies, and make it easier for the brine to cover the resin particles near the bottom of the water distributor, so that the resin at the bottom can fully contact the brine and improve the softening effect of the resin particles.

[0022] Preferably, in the direction from near the connection portion to away from the connection portion, the first guide portion extends obliquely from the radially inner side to the radially outer side of the water distributor.

[0023] In this solution, by extending the first guide section from the radial inner side to the radial outer side of the water distributor in the direction from near the connection part to away from the connection part, it is more conducive to guiding the water flow to the outer side of the water distributor in the circumferential direction, increasing the range of brine contact with the resin, increasing the water distribution range of the water distributor, and at the same time, it plays a role in converging and guiding the brine flowing out of the outlet water hole, further improving the softening effect of the resin particles.

[0024] Preferably, the external guide includes a second guide portion, which is disposed at the end of the first guide portion away from the inner groove. One end of the second guide portion is connected to the first guide portion, and the other end of the second guide portion is provided with the connecting portion.

[0025] In the direction from near the connection to away from the connection, the second guide portion extends radially outward from the radially inner side of the water distributor.

[0026] In this design, the second guide section extends radially outward from the inner side of the water distributor in a direction from near the connection to away from the connection. This allows the second guide section to direct the water flow outward after the brine enters the connection from the pipe. It also works in conjunction with the inclined inner wall to ensure that the water flow is evenly distributed outward, reducing the generation of eddies.

[0027] Preferably, the extension direction of the second guide portion is consistent with the extension direction of the inner sidewall.

[0028] In this design, by setting the extension direction of the second guide section to be consistent with the extension direction of the inner wall, the guiding direction of the second guide section on the water flow can be consistent with the inner wall, and the two can work together better, thereby diverting the water flow to the circumferential outer side of the water distributor and further reducing the generation of eddies.

[0029] Preferably, the water distributor further includes a plurality of guide vanes, the extension direction of which forms an angle with the axial direction of the water distributor;

[0030] Multiple guide vanes are circumferentially spaced in the flow guide cavity, and at least one outflow water hole is provided between two adjacent guide vanes.

[0031] In this design, the water distributor includes multiple guide vanes. The extension direction of the guide vanes forms an angle with the axis of the water distributor, thereby enabling the guide vanes to generate a centrifugal effect. The guide vanes guide the water flow to the outside of the water distributor, making the water flow distribution in the guide cavity more uniform. By setting at least one outlet water hole between two guide vanes, the water flow after centrifugation by the guide vanes can be discharged from the outlet water hole more quickly, improving the water distribution efficiency of the water distributor. At the same time, it maintains a consistent flow rate at each outlet water hole, and the water flow is more uniformly distributed in the circumferential direction of the water distributor, further enhancing the softening effect of the resin particles.

[0032] This utility model also provides a water softener, which includes the aforementioned water distributor.

[0033] The positive and progressive effects of this utility model are as follows:

[0034] The water distributor has a flow guiding chamber inside, and a connecting part at one end for connecting to a pipe. Saltwater enters the flow guiding chamber from the connecting part. An inner groove is provided at the end of the water distributor away from the connecting part, pointing towards the flow guiding chamber. Multiple internal water outlet holes are provided on the inner wall of the inner groove, allowing water in the flow guiding chamber to flow out through these holes and cover the resin at the bottom of the water distributor. This ensures the resin at the bottom can fully contact the saltwater, improving the softening effect of the resin particles. Attached Figure Description

[0057] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the following embodiments.

[0058] This embodiment provides a water softener, which includes a water distributor 100 disposed inside a tank. The tank is also provided with a pipe for conveying brine, and the water distributor 100 is connected to the pipe.

[0059] like Figures 1-3 As shown, the water distributor 100 has a flow guiding cavity 110 inside, and one end of the water distributor 100 has a connecting part 120 for connecting to a pipe. The water distributor 100 has an inner groove 400 recessed in the direction of the flow guiding cavity 110 at the end away from the connecting part 120. The inner groove 400 includes an inner sidewall 410, and the inner sidewall 410 has a plurality of inner water outlet holes 411 penetrating the inner sidewall 410.

[0060] The water distributor 100 has a flow guiding cavity 110 inside, and a connecting part 120 at one end of the water distributor 100. The connecting part 120 is used to connect a pipe, and the brine enters the flow guiding cavity 110 of the water distributor 100 from the connecting part 120. By providing an inner groove 400 in the direction of the flow guiding cavity 110 at the end of the water distributor 100 away from the connecting part 120, and providing a plurality of inner water outlet holes 411 through the inner sidewall 410 of the inner groove 400, water in the flow guiding cavity 110 can flow out from the inner water outlet holes 411, thereby covering the resin at the bottom of the water distributor 100, so that the resin at the bottom can fully contact the brine and improve the softening effect of the resin particles.

[0061] In the direction from near the connection portion 120 to away from the connection portion 120, the inner sidewall 410 extends radially outward from the radially inner side of the water distributor 100, thereby buffering the vertically downward impact of brine and reducing brine collision. The outwardly extending inner sidewall 410 can guide the water flow, causing the water flow direction to tilt outward and reducing the generation of eddies. In this embodiment, the inclination angle of the inner sidewall 410 is 5° to 10°. In other embodiments, the inclination angle of the inner sidewall 410 can also be selected from other angles that are considered suitable by those skilled in the art.

[0062] The water distributor 100 also includes an outer peripheral wall 500, which has multiple outlet water holes 530 penetrating through it. The brine in the guide cavity 110 can flow out into the resin on the outside through the outlet water holes 530. In the direction from near the connecting part 120 to away from the connecting part 120, the outer peripheral wall extends radially inward from the radially outer side of the water distributor 100. The lower half of the water distributor 100 is W-shaped, which can reduce the impact of water flow on the outer peripheral wall 500 and guide the water flow climbing the wall, causing the water flow to flow outward and reducing the generation of eddies.

[0063] The outer peripheral wall 500 includes a first part 510 and a second part 520 along the axial direction of the water distributor 100. The first part 510 is located at the end of the second part 520 away from the connecting part 120 and is connected to the second part 520. The inner diameter of the second part 520 is larger than the inner diameter of the first part 510, so that the inner side of the outer peripheral wall 500 is stepped, which further reduces the impact of water flow on the outer peripheral wall 500 and reduces the generation of eddies.

[0064] In this embodiment, the outer peripheral wall 500 is divided into two parts: a first part 510 and a second part 520. In other embodiments, the outer peripheral wall 500 may also be divided into three or more parts, and those skilled in the art can choose according to actual needs.

[0065] The water distributor 100 includes an outer guide member 200 and an inner guide member 300. The outer guide member 200 covers the inner guide member 300, and the outer guide member 200 and the inner guide member 300 form a guide cavity 110. The inner guide member 300 includes an outer peripheral wall 500, and the outer peripheral wall 500 is provided with a plurality of outlet water holes 530 penetrating the outer peripheral wall 500. The outer guide member 200 includes a first guide portion 210, the lower end of which extends to the outer peripheral side of the outer peripheral wall 500, and a gap is provided between the inner peripheral surface of the first guide portion 210 and the outer peripheral surface of the outer peripheral wall 500. When the brine in the guide cavity 110 flows out from the outlet water hole 530, the water flows into the gap between the inner circumferential surface of the first guide section 210 and the outer circumferential surface of the outer circumferential wall 500. The first guide section 210 can guide the outflowing brine downward, reduce the generation of eddies, and make it easier for the brine to cover the resin particles near the bottom of the water distributor 100, so that the resin at the bottom can fully contact the brine and improve the softening effect of the resin particles.

[0066] In this embodiment, the water distributor 100 is divided into an outer guide member 200 and an inner guide member 300, which together form a guide cavity 110. In other embodiments, the water distributor 100 may be a single unit or divided into multiple parts, and those skilled in the art can choose according to the actual situation.

[0067] In the direction from near the connecting part 120 to away from the connecting part 120, the first guide part 210 extends radially outward from the radially inner side of the water distributor 100, which is more conducive to guiding the water flow to the outer side of the water distributor 100 in the circumferential direction, increasing the range of brine contact with the resin, increasing the water distribution range of the water distributor 100, and at the same time, it plays a role in converging and guiding the brine flowing out of the outlet water hole 530, further improving the softening effect of the resin particles. The tilt angle of the first guide part 210 can be set to be greater than 10°, and the maximum tilt angle is determined by the inlet size of the tank, so as to avoid the water distributor 100 being difficult to insert into the tank due to an excessively large tilt angle.

[0068] The external guide member 200 includes a second guide portion 220, which is located at the end of the first guide portion 210 away from the inner groove 400. One end of the second guide portion 220 is connected to the first guide portion 210, and the other end of the second guide portion 220 is provided with a connecting portion 120. In the direction from near the connecting portion 120 to away from the connecting portion 120, the second guide portion 220 extends radially outward from the radially inner side of the water distributor 100. Thus, when brine enters the connecting portion 120 from the pipe, the second guide portion 220 can guide the water flow direction to be inclined outward. At the same time, it cooperates with the inclined inner wall 410 to make the water flow evenly distributed to the outside and reduce the generation of eddies.

[0069] The extension direction of the second guide section 220 is consistent with the extension direction of the inner wall 410, so that the guiding direction of the second guide section 220 to the water flow is consistent with the inner wall 410. The two can work together better, thereby diverting the water flow to the circumferential outer side of the water distributor 100, further reducing the generation of eddies.

[0070] In this embodiment, the tilt direction of the second guide section 220 can be 5° to 10°. The angle should not be too large or too small. If the angle is too large, the guiding effect will not be achieved, and if the angle is too small, the water flow will tilt too little to the outside, and there is still a possibility that the resin will rush downward. In other embodiments, other tilt angles of the second guide section 220 that are considered appropriate by those skilled in the art can also be selected.

[0071] The water distributor 100 also includes multiple guide vanes 600. The extension direction of the guide vanes 600 forms an angle with the axial direction of the water distributor 100, thereby enabling the guide vanes 600 to generate a centrifugal effect. The guide vanes 600 guide the water flow to flow to the outside of the water distributor 100, and also make the water flow distribution in the guide cavity 110 more uniform. The multiple guide vanes 600 are circumferentially spaced in the guide cavity 110, and at least one outlet water hole 530 is provided between two adjacent guide vanes 600. This allows the water flow after centrifugation by the guide vanes 600 to be discharged from the outlet water hole 530 more quickly, improving the water distribution efficiency of the water distributor 100. At the same time, it keeps the flow rate of each outlet water hole 530 consistent, and the water flow is more uniformly distributed in the circumferential direction of the water distributor 100, further improving the softening effect of the resin particles.

[0072] In this embodiment, two outlet water holes 530 are provided between two adjacent guide vanes 600, thereby further improving the uniformity of the water flow from the outlet water holes 530. In other embodiments, the number of outlet water holes 530 between two adjacent guide vanes 600 can be one, three or more, and those skilled in the art can choose according to the actual situation.
