Description

Technical Field

[0001] The invention relates to the technical field of water softeners, and in particular provides a water softener and a water distributor thereof. Background Art

[0002] A water softener is a device used to remove hardness ions from water, and is commonly used in homes and industries. Hardness ions mainly include calcium ions and magnesium ions, which combine with other substances in the water to form scale, causing damage to pipes, equipment, and home appliances. A water softener uses ion exchange technology to exchange hardness ions in water with sodium ions, thereby softening the water.

[0003] A water circuit conversion valve is arranged on the top of the soft water tank of the existing water softener, and a water distributor is arranged in the softening pipe. A space for accommodating softening resin is formed between the tank body of the soft water tank and the water distributor, and the space is filled with softening resin. The first interface of the water circuit conversion valve is connected to the tap water pipe through the raw water inlet pipe, and the second interface of the water circuit conversion valve is directly connected to the space for accommodating softening resin. The water distributor includes a central pipe and a water distributor connected to the lower end of the central pipe, and the water distributor includes a roughly columnar shell, the opening at the top of the shell is connected to the lower end of the central pipe, and a large number of strip holes are evenly distributed on the circumferential side wall of the shell around the central axis of the shell. The third interface of the water circuit conversion valve is connected to the upper end of the central pipe, the fourth interface of the water circuit conversion valve is connected to the soft water outlet pipe, the fifth interface of the water circuit conversion valve is connected to the salt tank through the salt water inlet pipe, and the sixth interface of the water circuit conversion valve is connected to the waste water tank.

[0004] When softening water, the water circuit conversion valve connects the first interface with the second interface, and the third interface with the fourth interface. The raw water provided by the tap flows through the raw water inlet pipe and the water circuit conversion valve in turn and then flows into the space accommodating the softening resin. After flowing through the softening resin, the raw water becomes soft water. After passing through the strip holes on the water distribution parts, the soft water flows through the center pipe, the water circuit conversion valve and the soft water outlet pipe in turn and then flows out.

[0005] After the water softener has been used for a period of time, a large amount of calcium and magnesium ions are adsorbed on the softening resin, and its ability to adsorb calcium and magnesium ions decreases. At this time, the softening resin needs to be regenerated. When regenerating the softening resin, the water circuit conversion valve connects the first interface with the third interface, the fifth interface with the third interface, and the second interface with the sixth interface. There is a Venturi channel between the first interface and the third interface of the water circuit conversion valve. The raw water flows through the raw water inlet pipe and the water circuit conversion valve in turn and then flows into the central tube. The raw water generates negative pressure during the flow of the Venturi channel, so that the brine in the salt tank is sucked into the mixed flow through the brine inlet pipe and then flows into the central tube. The mixed brine passes through the strip holes on the water distribution part and flows into the space accommodating the softening resin. The brine flows through the softening resin and then flows through the water circuit conversion valve and the waste water pipe and then flows out.

[0006] However, the flow rate during the softening process is much larger than the flow rate during the regeneration process. For example, the flow rate during the softening process is 25L / min, and the flow rate during the regeneration process is 1.2L / min. In order to meet the flow rate during the softening process, the flow area of ​​the strip holes on the water distribution parts is large and the number is large. However, the flow rate during the regeneration process is small, and the pressure of the brine in the water distribution parts is small. When the brine in the water distribution parts flows out from the strip holes, it cannot flow to the position far away from the strip holes around the water distribution parts. As a result, most of the brine flowing out of the water distribution parts is distributed in a small range around the water distributor and then flows out. The softening resin in the soft water tank far away from the water distributor cannot contact most of the brine flowing out of the water distribution parts and cannot be effectively regenerated.

[0007] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention

[0008] The present invention aims to solve the above technical problem, namely, to solve the problem that the water distributor of the existing water softener makes the softening resin in the soft water tank unable to fully contact the salt water and cannot be effectively regenerated.

[0009] In a first aspect, the present invention provides a water distributor for a water softener, wherein the water distributor is arranged in a soft water tank of the water softener, and a space for accommodating softening resin is formed between the soft water tank and the water distributor, and is characterized in that the water distributor includes a first water distributor and a second water distributor and a first water path and a second water path respectively connected to the first water distributor and the second water distributor, wherein the first water distributor and the second water distributor are respectively provided with a plurality of first water holes and a plurality of second water holes, the space, the first water holes and the first water path are connected in sequence to form a raw water softening flow path, the second water path, the second water holes and the space are connected in sequence to form a resin regeneration flow path, the second water holes are arranged so that a single flow area is smaller than a single flow area of ​​the first water holes, and when the brine flows through the resin regeneration flow path, the distance over which the brine is sprayed from the second water hole is not less than half of the radius of the soft water tank.

[0010] In the preferred technical solution of the above-mentioned water distributor, the center of the second water distribution member is located on the vertical central axis of the soft water tank, and the distance between the outer peripheral edge of the second water distribution member and the center is not less than half of the radius of the soft water tank.

[0011] In the preferred technical solution of the above-mentioned water distributor, the second water distribution member includes a plurality of branch pipes evenly distributed around the vertical center axis of the soft water tank, the inlet ends of the plurality of branch pipes are connected to the second water channel, and the plurality of second water holes are distributed on the plurality of branch pipes.

[0012] In a preferred technical solution of the water distributor, the flow areas of the plurality of second water holes sequentially distributed on each of the branch pipes in a direction away from the second water channel decrease sequentially.

[0013] In the preferred technical solution of the above-mentioned water distributor, the branch pipe is a hollow fiber membrane or the material of the branch pipe is a memory alloy.

[0014] In the preferred technical solution of the above-mentioned water distributor, the second water channel is coaxial with the vertical center axis of the soft water tank.

[0015] In the preferred technical solution of the above-mentioned water distributor, the water distributor includes a first center tube and a second center tube sleeved in the first center tube; the channel between the first center tube and the second center tube and the internal channel of the second center tube respectively form the first waterway and the second waterway, or the channel between the first center tube and the second center tube and the internal channel of the second center tube respectively form the second waterway and the first waterway.

[0016] In a preferred technical solution of the above-mentioned water distributor, there are multiple second water distribution components, and the multiple second water distribution components are distributed along the vertical center axis of the soft water tank.

[0017] In the preferred technical solution of the above-mentioned water distributor, among two adjacent second water distribution parts, the flow area of ​​the second water flow hole on the second water distribution part close to the downstream of the second water channel is smaller than the flow area of ​​the second water flow hole at the corresponding position on the second water distribution part close to the upstream of the second water channel.

[0018] When the above technical solution is adopted, the water distributor includes a first water distribution member and a second water distribution member and a first water path and a second water path respectively connected to the first water distribution member and the second water distribution member, and a plurality of first water holes and a plurality of second water holes are respectively arranged on the first water distribution member and the second water distribution member. The space for accommodating softening resin in the soft water tank of the water softener, the first water hole and the first water path are connected in sequence to form a raw water softening flow path, and the second water path, the second water hole and the space are connected in sequence to form a resin regeneration flow path. The second water hole is arranged so that a single flow area is smaller than a single flow area of ​​the first water hole, and when the brine flows through the resin regeneration flow path, the distance over which the brine is sprayed from the second water hole is not less than half of the radius of the soft water tank.

[0019] By such an arrangement, when the raw water is softened, the raw water flows along the raw water softening flow path to convert the raw water into soft water. When the softening resin is regenerated, the salt water flows along the resin regeneration flow path to achieve the regeneration of the softening resin. The flow area of ​​a single second water hole is smaller than the flow area of ​​a single first water hole, and when the salt water flows through the resin regeneration flow path, the distance that the salt water is sprayed from the second water hole is not less than half of the radius of the soft water tank, so that the salt water flowing out of the second water hole can flow through most of the softening resin, so that the softening resin can be more fully contacted with the salt water, thereby more effectively achieving the regeneration of the softening resin.

[0020] Preferably, the center of the second water distribution member is located on the vertical central axis of the soft water tank, and the distance between the outer peripheral edge of the second water distribution member and the center is not less than half of the radius of the soft water tank.

[0021] Through such an arrangement, the salt water flowing out of the second water passage hole can cover a larger area, so that the softening resin can be more fully contacted with the salt water, thereby improving the regeneration effect of the softening resin.

[0022] Preferably, the second water distribution member includes a plurality of branch pipes evenly distributed around the vertical center axis of the soft water tank, the inlet ends of the plurality of branch pipes are connected to the second water channel, a plurality of second water holes are distributed on the plurality of branch pipes, and the flow areas of the plurality of second water holes distributed sequentially on each branch pipe in a direction away from the second water channel decrease sequentially.

[0023] Since multiple second water holes are distributed on the branch pipe, the water pressure will gradually decrease along the direction of water flow in the branch pipe. The flow areas of multiple second water holes distributed in sequence in the direction away from the second water channel on each branch pipe are reduced in sequence, so that the distances of salt water sprayed from the second water holes at different positions on the branch pipe tend to be the same, so that the softening resins at different positions can fully contact the salt water.

[0024] Preferably, the branch tube is a hollow fiber membrane or the material of the branch tube is a memory alloy.

[0025] The branch pipe is configured as a hollow fiber membrane, and a larger number of branch pipes can be configured, so that the second water holes are more fully distributed in the softening pipe, so that the softening resin and the brine are more fully in contact, and because the hollow limit membrane has a certain elasticity, it is convenient for the second water distribution member to be installed into the soft water tank from the smaller installation hole on the soft water tank. The material of the branch pipe is configured as a memory alloy, so that the second water distribution member can be installed into the soft water tank from the smaller installation hole on the soft water tank.

[0026] In a second aspect, the present invention further provides a water softener, comprising the water distributor of the water softener described in any one of the above technical solutions.

[0027] It should be noted that the water softener has all the technical effects of the water distributor of the water softener described in any of the above technical solutions, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] First, those skilled in the art should understand that the embodiments described below are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0036] It should be noted that, in the description of the invention, the terms “first” and “second” are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0037] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a direct connection, or an indirect connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Based on the problem mentioned in the background technology that the water distributor of the existing water softener makes it impossible for the softening resin in the soft water tank to fully contact the brine and cannot be effectively regenerated, the present invention provides a water distributor of the water softener, the water distributor is arranged in the soft water tank of the water softener, and a space for accommodating the softening resin is formed between the soft water tank and the water distributor, the water distributor comprises a first water distributor and a second water distributor and a first water path and a second water path respectively connected to the two, the first water distributor and the second water distributor are respectively provided with a plurality of first water holes and a plurality of second water holes, the space, the first water holes and the first water path are connected in sequence to form a raw water softening flow path, the second water path, the second water holes and the space are connected in sequence to form a resin regeneration flow path, the second water holes are arranged so that a single flow area is smaller than a single flow area of ​​the first water hole, and when the brine flows through the resin regeneration flow path, the distance over which the brine is sprayed from the second water hole is not less than half of the radius of the soft water tank.

[0039] By such an arrangement, when the raw water is softened, the raw water flows along the raw water softening flow path to convert the raw water into soft water. When the softening resin is regenerated, the salt water flows along the resin regeneration flow path to achieve the regeneration of the softening resin. The flow area of ​​a single second water hole is smaller than the flow area of ​​a single first water hole, and when the salt water flows through the resin regeneration flow path, the distance that the salt water is sprayed from the second water hole is not less than half of the radius of the soft water tank, so that the salt water flowing out of the second water hole can flow through most of the softening resin, so that the softening resin can be more fully contacted with the salt water, thereby more effectively achieving the regeneration of the softening resin.

[0040] Refer to the following Figures 1 to 4 Herein, the present invention is introduced. Figure 1 It is a structural schematic diagram of a soft water tank assembly of a water softener according to an embodiment of the present invention; Figure 2 is a top view of a soft water tank assembly of a water softener according to an embodiment of the present invention; Figure 3 yes Figure 2 Sectional view of the midline surface AA; Figure 4 It is a structural schematic diagram of a water distributor of a water softener according to an embodiment of the present invention.

[0041] like Figures 1 to 3 As shown, the water softener includes a soft water tank assembly, which includes a soft water tank 1 and a water distributor 2 disposed in the soft water tank 1. A resin containing space 11 for containing softened resin is formed between the soft water tank 1 and the water distributor 2. The resin containing space 11 is filled with softened resin. A mounting hole is formed on the top of the soft water tank 1. A connecting piece 12 is installed on the mounting hole. The connecting piece 12 is roughly columnar. An external thread is formed on the outer peripheral wall of the connecting piece 12. An internal thread is formed on the inner wall of the mounting hole. The external thread on the connecting piece 12 is screwed together with the internal thread of the mounting hole so that the connecting piece 12 is installed at the mounting hole. A first opening 121 and a second opening 122 are formed on the connecting piece 12.

[0042] like Figure 3 and Figure 4 As shown, the water distributor 2 includes a first water distribution member 21, a second water distribution member 22, and a first water path and a second water path connected to the first water distribution member 21 and the second water distribution member 22, respectively. A plurality of first water holes and a plurality of second water holes are respectively provided on the first water distribution member 21 and the second water distribution member 22. The resin containing space 11, the first water hole and the first water path are connected in sequence to form a raw water softening flow path, and the second water path, the second water hole and the resin containing space 11 are connected in sequence to form a resin regeneration flow path. The second water hole is arranged so that a single flow area is smaller than a single flow area of ​​the first water hole, and when the salt water flows through the resin regeneration flow path, the distance that the salt water is sprayed out from the second water hole is not less than half of the radius of the soft water tank 1.

[0043] like Figure 3 and Figure 4 As shown, specifically, the first water distribution member 21 includes a shell that is roughly cylindrical, and the first water passage hole is a long strip hole uniformly distributed around the vertical center axis of the shell on the side wall of the shell. The first water distribution member 21 is arranged at the central bottom of the soft water tank 1, and an opening is formed on the top of the first water distribution member 21, and the opening is connected to the first center pipe 23 extending upward. The first center pipe 23 is coaxial with the soft water tank 1. The second water distribution member 22 includes a diverter 221 and a plurality of hollow fiber membranes 222, and the diverter 221 includes a diverter shell, and a plurality of through holes are formed on the side walls of the diverter shell. The two ends of the hollow fiber membrane 222 are respectively connected to the two through holes on the diverter shell, and each hollow fiber membrane 222 is roughly U-shaped, and each hollow fiber membrane 222 is distributed along its length direction with a plurality of micropores as the second water passage hole, and the flow area of ​​a single micropore is smaller than the flow area of ​​a single long strip hole. An opening is formed at the top of the diverter housing, and a second central tube 24 extending upward is connected to the opening. The second central tube 24 is arranged in the first central tube 23 and is coaxial with the second central tube 24. The lower part of the diverter 221 passes through the bottom of the housing of the first water distribution member 21, so that the through hole on the diverter housing is located outside the housing of the first water distribution member 21. The U-shaped hollow fiber membrane 222 extends from the diverter 221 as a whole, roughly along the radial direction of the soft water tank 1, away from the diverter 221, and extends to a position close to the side wall of the soft water tank 1. The channel between the first central tube 23 and the second central tube 24 forms a first waterway, and the channel in the second central tube 24 forms a second waterway. The upper end of the first waterway is connected to the second opening 122 on the connecting member 12. The upper end of the second central tube 24 passes through the connecting member 12.

[0044] like Figure 3 and Figure 4 As shown, the water distributor 2 also includes a third water distribution component 25, which includes a roughly cylindrical shell, the bottom of which is provided with a hole for the first center tube 23 to pass through, a plurality of long holes are formed on the outer peripheral wall of the shell, and the top of the shell is an open mouth, and an annular opening is formed between the edge structure of the open mouth and the first center tube 23, and the annular opening is connected to the first opening 121 on the connecting member 12.

[0045] When softening water, raw water flows in from the first opening 121 of the connecting piece 12, and then flows into the resin containing space 11 after being dispersed by the third water distribution piece 25. The raw water becomes soft water after flowing through the softened resin. The soft water flows in from the first water hole on the first water distribution piece 21, and then flows out from the second opening 122 on the connecting piece 12 along the channel between the first center pipe 23 and the second center pipe 24 (i.e., the first water channel).

[0046] When the softened resin in the resin containing space 11 needs to be regenerated, the salt water flows from the channel (i.e., the second water path) of the second central tube 24 to the diverter 221 of the second water distribution member 22, and the salt water is divided into multiple streams at the diverter 221, which flow into the hollow fiber membrane filaments 222 and are sprayed out from the micropores (i.e., the second water holes) on the hollow fiber membrane filaments 222. The sprayed salt water covers most of the softened resin, and the salt water regenerates the softened resin by ion exchange with the softened resin. Finally, the waste water generated passes through the long strip holes on the third water distribution member 25 and flows out from the first opening 121 on the connecting member 12.

[0047] Through such an arrangement, during the regeneration process of the softening resin, the softening resin can be more fully contacted with the brine, thereby more effectively achieving the regeneration of the softening resin.

[0048] The second center tube 24 is inserted into the first center tube 23, the channel between the first center tube 23 and the second center tube 24 forms a first waterway, and the channel in the second center tube 24 forms a second waterway, which makes the structure of the water distributor 2 more compact, occupies less space, and is easy to install.

[0049] The second water distributor 22 includes a flow divider 221 and a plurality of hollow fiber membranes 222, each of which has a plurality of micropores as second water holes distributed along its length. This facilitates the second water holes to more fully cover the softening resin, so that the softening resin and the sprayed salt water are more fully in contact, and facilitates the water distributor 2 to be placed into the soft water tank 1 from the mounting hole at the top of the soft water tank 1.

[0050] It should be noted that the two ends of the hollow fiber membrane filaments 222 are respectively connected to the two through holes on the diverter housing, and each hollow fiber membrane filament 222 is roughly U-shaped. This is only a specific setting method, and it can be adjusted in actual applications. For example, the first end of each hollow fiber membrane filament is connected to the through hole on the diverter housing, and the second end is blocked. Each hollow fiber membrane filament extends from the first end to the second end along the radial direction of the soft water tank 1 in the direction away from the diverter 221. In addition, the diverter 221 may not be provided, and multiple hollow fiber membrane filaments 222 are directly connected to the lower end of the first central tube 23. In addition, the hollow fiber membrane filaments can also be replaced by multiple branch pipes of other sizes connected to the lower end of the first central tube 23. The branch pipes can be made of memory alloy material to facilitate the installation of the second water distribution member 22.

[0051] It should also be noted that the flow area of ​​the second water hole and the number of the second water holes are determined according to the diameter of the soft water tank and the flow rate of the brine. When the diameter of the soft water tank is determined, the distance that the brine is sprayed out of the second water hole is basically determined. The distance that the brine is sprayed out of the second water hole is related to the water pressure of the brine in the second water pass part. The water pressure of the brine in the second water pass part is related to the flow rate of the brine, the flow area of ​​the second water hole, and the number of the second water holes. Therefore, when setting the flow area of ​​the second water hole and the number of the second water holes, they can be determined according to the diameter of the soft water tank and the flow rate of the brine. The specific calculation method belongs to the conventional design in this field and will not be repeated here. Of course, the flow area of ​​the second water hole and the number of the second water holes can also be determined through experiments during the design stage.

[0052] In another feasible embodiment, different from the above embodiment, the second water distribution member includes a disc-shaped shell, a connecting hole is set at the top center position of the disc-shaped shell, the connecting hole is connected to the lower end of the second center tube 24, the disc-shaped shell is covered with a large number of micropores, and the radius of the disc-shaped shell is not less than half of the radius of the second soft water tank.

[0053] In another feasible embodiment, different from the above embodiment, the channel between the first center tube 23 and the second center tube 24 forms a second water channel connected to the second water distribution component, and the channel in the second center tube 24 forms a first water channel connected to the first water distribution component.

[0054] In another feasible embodiment, different from the above embodiment, the internal channel of the first central tube forms a first water path connected to the first water distribution member, a plurality of vertical tubes are evenly distributed around the first central tube, the upper ends of the plurality of vertical tubes are connected to a main pipe and pass through the connecting member 12, the plurality of vertical tubes and the channels in the main pipe form a second water path, the lower ends of the plurality of vertical tubes are connected to the first ends of the plurality of branch pipes, the second ends of the plurality of second branch pipes are blocked, each branch pipe extends radially inward from the first end to the second end of the soft water tank 1, and a plurality of second water holes are formed on each branch pipe.

[0055] In another feasible embodiment, the second water distribution member can be set to be substantially the same size as the first water distribution member, and the flow area of ​​the second water hole is smaller than the flow area of ​​the first water hole. Compared with the prior art, the regeneration effect of the softened resin can also be improved, but the regeneration effect of the softened resin is not as good as the above embodiment.

[0056] In another feasible embodiment, the third water distribution member 25 in the above embodiment may not be included.

[0057] Preferably, based on the above-mentioned embodiment in which the second water distribution member includes branch pipes, the flow areas of the plurality of second water holes sequentially distributed on each branch pipe in a direction away from the second water channel decrease sequentially.

[0058] In this way, the distances over which the salt water is sprayed from the second water holes at different positions on the branch pipe tend to be the same, so that the softening resins at different positions can fully contact the salt water.

[0059] Preferably, based on the above embodiments, there are multiple second water distribution members, and the multiple second water distribution members are distributed along the vertical center axis of the soft water tank. Through such an arrangement, the softened resins at different heights in the soft water tank can start to contact the salt water at the same time, and the softened resins at different heights can basically complete regeneration at the same time, which can shorten the duration of the softened resin regeneration process as a whole and improve the softened resin regeneration speed.

[0060] Preferably, in two adjacent second water distribution members, the flow area of ​​the second water hole on the second water distribution member near the downstream of the second water channel is smaller than the flow area of ​​the second water hole at the corresponding position on the second water distribution member near the upstream of the second water channel. Through such an arrangement, the flow rate of the salt water sprayed by the second water distribution members at different heights can be made consistent, so that the regeneration process of the softening resin at different heights can be synchronized.

[0061] In addition, the present invention also provides a water softener, which includes the water distributor of the water softener in any one of the above embodiments.

[0062] It should be noted that the water softener may be a water softener having only the water softening function and the resin regeneration function, or may be a water softener also having a water purification function, a heating function or other additional functions.

[0063] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
