Abstract
Description
Technical Field
[0001] This utility model relates to the field of water softeners, and in particular to a water softener resin tank and a water softener. Background Technology
[0002] As people's living standards improve, water softeners have become increasingly common in households. A water softener's resin tank contains resin at the bottom, and the process includes resin regeneration and softened water output. During softened water output, raw water enters the softener through the raw water inlet into the resin tank. Inside the resin tank, calcium and magnesium ions in the water interact with sodium ions on the resin, removing most of the calcium and magnesium ions and reducing water hardness. The softened water then flows out through the softened water outlet for user use. During resin regeneration, concentrated brine flows into the resin tank through the brine inlet. As the concentrated brine passes through the resin, the calcium and magnesium ions adsorbed on the resin exchange with the sodium ions. Because sodium ions have a stronger binding force with the resin, the calcium and magnesium ions are displaced and discharged with the brine through the wastewater outlet.
[0003] However, the salt efficiency of resin tanks in water softeners in the industry is generally not high. The main reason is that the brine cannot fully contact the resin, resulting in low regeneration efficiency and thus low overall salt efficiency. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the defect of low salt efficiency of resin tanks in existing water softeners, and to provide a water softener resin tank and water softener.
[0005] The present invention solves the above-mentioned technical problems through the following technical solution:
[0006] A water softener resin tank includes a tank body with a brine inlet and a wastewater outlet. The brine inlet is used to allow concentrated brine to flow into the tank body, and the wastewater outlet is used to allow wastewater generated during resin regeneration to flow out. A flow divider is provided inside the tank body, dividing the tank body into a first receiving cavity located above the flow divider and a second receiving cavity located below the flow divider in the height direction of the tank body.
[0007] The flow divider is used to hold the resin, and the flow divider is provided with a plurality of first connecting holes;
[0008] The concentrated brine is configured to flow into the second accommodating cavity through the brine inlet and into the resin through a plurality of first connecting holes.
[0009] In this design, concentrated brine flows into the second receiving chamber. As more and more concentrated brine flows in, it reaches the resin through the first connecting hole on the distributor seat, thus coming into contact with the resin. This arrangement ensures that the concentrated brine flows into the resin from bottom to top, allowing for sufficient contact between the concentrated brine and the resin, thereby improving salt efficiency.
[0010] Preferably, the resin tank further includes a plurality of diversion columns disposed in the second accommodating cavity, the plurality of diversion columns being spaced apart, and each diversion column being provided with a plurality of second connecting holes;
[0011] The second connecting hole connects the interior of the second accommodating cavity and the inside of the diversion column.
[0012] In this design, the second connecting hole allows the concentrated brine to flow out more quickly, which is beneficial for the concentrated brine to come into more complete contact with the resin.
[0013] Preferably, the plurality of diversion columns are arranged in parallel, and the axial directions of the diversion columns, the axial direction of the first connecting hole, and the axial direction of the tank body are parallel to each other;
[0014] And / or, a plurality of the first connecting holes are evenly distributed on the distributor seat.
[0015] In this design, the aforementioned structure, with multiple parallel flow dividers, allows the second connecting holes on them to function more effectively, thereby ensuring sufficient contact between the concentrated brine and the resin. The multiple first connecting holes are evenly distributed on the flow divider seat, enabling the concentrated brine to flow into the resin more uniformly, further facilitating sufficient contact between the concentrated brine and the resin.
[0016] Preferably, the diversion column has a first end and a second end along the axial direction;
[0017] The first end of the diversion column is attached to and connected to the diversion seat;
[0018] The second end of the diversion column has a mating surface that is adapted to the bottom of the tank body so as to fit against the bottom of the tank body.
[0019] In this design, the above-mentioned configuration results in a large contact area between the diversion column and the bottom of the diversion plate and tank body. This allows for reliable connection of both ends of the diversion column to the diversion plate and tank body, ensuring the diversion seat functions reliably. Furthermore, the connection of both ends of the diversion column to the bottom of the diversion plate and tank body provides support for the diversion plate, helping to maintain its position and ensuring reliable and sufficient contact between the concentrated brine and the resin.
[0020] Preferably, the brine inlet is located at the top of the tank body, and the resin tank further includes a guide pipe;
[0021] The diverter seat is also provided with a third connecting hole. The first end of the guide tube is embedded in the brine inlet and connected to the brine inlet. The second end of the guide tube is connected to the third connecting hole so that the concentrated brine can be passed to the second accommodating cavity through the guide tube.
[0022] In this solution, the above-mentioned structure is adopted, and the concentrated brine entering from the brine inlet at the top of the tank body can flow into the second accommodating cavity in a relatively convenient and reliable manner through the guide pipe. Moreover, the guide pipe is located inside the tank body, which can better protect the guide pipe.
[0023] Preferably, a positioning seat is provided at the top of the diverter seat at the position corresponding to the third connecting hole, and the second end of the guide tube is embedded in the positioning seat.
[0024] In this scheme, the above-mentioned structural setting allows the positioning seat to position and stabilize the guide tube, so that the second end of the guide tube can be reliably positioned on the diversion seat, thereby allowing the concentrated brine to be reliably introduced into the second accommodating cavity.
[0025] Preferably, the top of the positioning seat is provided with a guide slope for guiding the flow tube;
[0026] And / or, the guide tube and the inner wall surface of the positioning seat are sealed together by a first sealing element.
[0027] In this design, the guide ramp guides the flow tube, facilitating its installation within the positioning seat. The sealed connection between the flow tube and the inner wall of the positioning seat prevents concentrated brine from entering between them, thus ensuring...
[0028] Preferably, the first end of the guide tube extends beyond the top of the brine inlet, and the end of the first end of the guide tube has a flanged structure;
[0029] The brine inlet is provided with a second seal at its top, and the flange structure is pressed onto the second seal.
[0030] Preferably, the tank body is further provided with a raw water inlet and a soft water outlet. The raw water inlet is connected to the first accommodating cavity and the soft water outlet. The brine inlet, the second accommodating cavity, the first accommodating cavity, and the wastewater outlet are sequentially connected to form a resin regeneration path. The raw water inlet, the first accommodating cavity, and the soft water outlet are sequentially connected to form a soft water outlet path. The resin regeneration path and the soft water outlet path are not simultaneously connected. The soft water outlet is located on the side wall of the tank body at a position corresponding to the bottom of the resin.
[0031] And / or, the diversion seat is sealed to the inner wall of the tank body by a third sealing element.

[0033] This utility model also provides a water softener, which includes the above-mentioned water softener resin tank.
[0034] In this solution, since the resin tank has a high salt efficiency, the water softener including the resin tank has a high salt efficiency, which is beneficial to improving the working efficiency of the water softener and extending its service life.
[0035] The positive and progressive effects of this utility model are as follows:

Consequently, the water softener including this resin tank has higher salt efficiency, which helps improve the softener's working efficiency and extend its service life. Attached Figure Description

[0068] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.
[0069] like Figures 1 to 6As shown, this embodiment provides a water softener resin tank and a water softener including the resin tank. The resin tank includes a tank body 10, with a brine inlet 20 and a wastewater outlet 40. The brine inlet 20 allows concentrated brine to flow into the tank body 10, and the wastewater outlet 40 allows wastewater generated during resin regeneration to flow out. A diversion seat 60 is provided inside the tank body 10, dividing it into a first receiving cavity 103 above the tank body 10 and a second receiving cavity 104 below the tank body 10 in the height direction. The diversion seat 60 carries the resin and has multiple first connecting holes 601. The concentrated brine is configured to flow into the second receiving cavity 104 through the brine inlet 20 and into the resin through the multiple first connecting holes 601.
[0070] In this embodiment, concentrated brine flows into the second receiving cavity 104. As more and more concentrated brine flows in, it reaches the resin through the first connecting hole 601 on the distributor seat 60, and then comes into contact with the resin. This arrangement ensures that the concentrated brine flows into the resin from bottom to top, allowing for sufficient contact between the concentrated brine and the resin, thereby improving salt efficiency.
[0071] It should be noted that the diameter of the first connecting hole 601 is configured to be smaller than the resin specification to prevent resin from falling below the distributor seat 60. The diameter of the resin is generally greater than 0.5 mm; as an example, the diameter of the first connecting hole 601 in this embodiment is less than 0.3 mm.
[0072] like Figure 2 , Figure 4 and Figure 5 As shown, the resin tank also includes a plurality of diversion columns 70 disposed within the second accommodating cavity 104. The plurality of diversion columns 70 are spaced apart, and each diversion column 70 is provided with a plurality of second connecting holes 701. The second connecting holes 701 connect the interior of the second accommodating cavity 104 and the interior of the diversion column 70.
[0073] With this configuration, the second connecting hole 701 allows the concentrated brine to flow out more quickly, which is beneficial for the concentrated brine to come into more complete contact with the resin.
[0074] As an example, the number of diversion columns 70 in this embodiment is eight. In other alternative embodiments, the number of diversion columns 70 can be set to any other number depending on the actual setup requirements.
[0075] Furthermore, multiple diversion columns 70 are arranged in parallel, and the axial directions of the diversion columns 70, the axial direction of the first connecting hole 601, and the axial direction of the tank body 10 are parallel to each other. The parallel arrangement of the multiple diversion columns 70 allows the second connecting holes 701 on them to function more effectively, thereby further ensuring sufficient contact between the concentrated brine and the resin.
[0076] As a preferred configuration, multiple first connecting holes 601 are evenly distributed on the flow divider 60. This arrangement, with the multiple first connecting holes 601 evenly distributed on the flow divider 60, allows the concentrated brine to flow into the resin more evenly, which is more conducive to achieving sufficient contact between the concentrated brine and the resin.
[0077] like Figure 2 and Figure 5 As shown, the diversion column 70 has a first end and a second end along the axial direction. The first end of the diversion column 70 is attached to and connected to the diversion seat 60. The second end of the diversion column 70 has a mating surface adapted to the bottom of the tank body 10 so as to fit against the bottom of the tank body 10.
[0078] With this configuration, the contact area between the diverter column 70 and the bottom of the diverter plate and tank body 10 is relatively large, and both ends of the diverter column 70 can be reliably connected to the diverter plate and tank body 10, thus enabling the diverter seat 60 to function reliably. Furthermore, since both ends of the diverter column 70 are connected to the bottom of the diverter plate and tank body 10 respectively, the diverter column 70 can support the diverter plate, helping to maintain its position and thus ensuring reliable and sufficient contact between the concentrated brine and the resin.
[0079] like Figures 2 to 6 As shown, the brine inlet 20 is located at the top of the tank body 10, and the resin tank also includes a guide pipe 80. The distributor seat 60 is also provided with a third connecting hole 602. The first end of the guide pipe 80 is embedded in the brine inlet 20 and connected to the brine inlet 20, and the second end of the guide pipe 80 leads to the third connecting hole 602, so as to pass the concentrated brine to the second receiving cavity 104 through the guide pipe 80.
[0080] In this embodiment, the brine entering from the brine inlet 20 at the top of the tank body 10 can flow into the second accommodating cavity 104 in a relatively convenient and reliable manner through the guide pipe 80. The guide pipe 80 is located inside the tank body 10, which can better protect the guide pipe 80.
[0081] Furthermore, a positioning seat 90 is provided at the top of the diversion seat 60 at a position corresponding to the third connecting hole 602, and the second end of the guide tube 80 is embedded in the positioning seat 90. The positioning seat 90 can position and stabilize the guide tube 80, so that the second end of the guide tube 80 can be reliably positioned on the diversion seat 60, thereby allowing the concentrated brine to be reliably introduced into the second receiving cavity 104.
[0082] like Figure 2 and Figure 4As shown, the top of the positioning base 90 is provided with a guide slope 901 for guiding the guide tube 80. The guide slope 901 guides the guide tube 80, making it easier to install the guide tube 80 within the positioning base 90. As an example, the guide slope 901 has a chamfered structure.
[0083] Furthermore, the inner wall surfaces of the guide tube 80 and the positioning seat 90 are sealed together by a first sealing element 100. In this embodiment, the sealed connection between the inner wall surfaces of the guide tube 80 and the positioning seat 90 prevents concentrated brine from entering between the inner wall surfaces of the guide tube 80 and the positioning seat 90, thus ensuring effective contact between the concentrated brine and the resin. As an example, such as Figure 2 and Figure 4 As shown, a receiving groove 801 is provided on the outer wall of the guide pipe 80, and the first sealing element 100 is installed in the receiving groove 801.
[0084] like Figure 2 and Figure 3 As shown, the first end of the guide tube 80 extends out of the top of the brine inlet 20, and the end of the first end of the guide tube 80 has a flange structure 802. The top of the brine inlet 20 is provided with a second seal 110, and the flange structure 802 is pressed onto the second seal 110.
[0085] In this embodiment, the flange structure 802 can reliably place the second seal 110 at the top of the brine inlet 20, thereby forming a reliable seal between the inner side of the flange structure 802 and the top of the brine inlet 20, which is beneficial to ensure that the concentrated brine introduced through the brine inlet 20 can flow into the guide pipe 80.
[0086] At least refer to Figure 1 and Figure 2 It is understood that the tank body 10 is also provided with a raw water inlet 30 and a soft water outlet 50. The raw water inlet 30 is connected to the first receiving cavity 103 and the soft water outlet 50. The brine inlet 20, the second receiving cavity 104, the first receiving cavity 103, and the wastewater outlet 40 are sequentially connected to form a resin regeneration path, and the raw water inlet 30, the first receiving cavity 103, and the soft water outlet 50 are sequentially connected to form a soft water outlet path. The resin regeneration path and the soft water outlet path are not connected simultaneously. The soft water outlet 50 is located on the side wall of the tank body 10 at a position corresponding to the bottom of the resin. In this embodiment, the soft water outlet 50 is located at a position corresponding to the bottom of the resin, so that the raw water flowing in from the raw water inlet 30 is softened by the resin before flowing into the soft water outlet 50, avoiding the raw water from flowing out directly without being softened by the resin.
[0087] Regarding the fact that the above-mentioned resin regeneration path and soft water outlet path are not simultaneously connected, the following supplementary explanations are provided: (1) During the resin regeneration process, both the raw water inlet 30 and the soft water outlet 50 are closed; during the soft water outlet process, both the brine inlet 20 and the wastewater outlet 40 are closed; (2) Both the raw water inlet 30, the soft water outlet 50, the brine inlet 20, and the wastewater outlet 40 are equipped with solenoid valves that control their opening or closing. During the resin regeneration process, the solenoid valves at the brine inlet 20 and the wastewater outlet 40 are open, while the solenoid valves at the raw water inlet 30 and the soft water outlet 50 are closed; correspondingly, during the soft water outlet process, the solenoid valves at the raw water inlet 30 and the soft water outlet 50 are open, while the solenoid valves at the brine inlet 20 and the wastewater outlet 40 are closed.
[0088] Furthermore, the diversion seat 60 is sealed to the inner wall of the tank body 10 by a third sealing element 120.
[0089] With this configuration, the diversion seat 60 is sealed to the inner wall of the tank body 10, so that the concentrated brine entering the second accommodating cavity 104 must pass through the diversion seat 60 before flowing into the first accommodating cavity 103, which helps to further ensure sufficient contact between the concentrated brine and the resin.
[0090] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the resin tank includes an upper tank 101 and a lower tank 102 connected together. A raw water inlet 30, a brine inlet 20, and a wastewater outlet 40 are located on the upper tank 101, and a soft water outlet 50 is located on the lower tank 102. Preferably, the brine inlet 20 is located at the top center of the upper tank 101. As an example, both the upper tank 101 and the lower tank 102 are made of PP material.
[0091] The upper tank 101 and the lower tank 102 are connected by spin welding. The opening of the lower tank 102 has a groove, which can be spin welded to the boss of the upper tank 101. The connection between the upper tank 101 and the lower tank 102 is simple and reliable, which helps to simplify the structure of the resin tank and also helps to ensure the normal use of the resin tank.
[0092] Among them, the aperture of the wastewater outlet 40 is relatively small, for example, its diameter is 0.5mm. The main purpose of setting it to be so small is to allow the wastewater to flow out for a longer time, indirectly increasing the contact time between the concentrated brine and the resin, thereby achieving a more complete and thorough replacement of calcium and magnesium ions in the resin by the brine.
[0093] like Figure 1 , Figure 2 and Figure 6As shown, the resin tank also includes a support boss 130 disposed on the outside of the tank body 10, and the support boss 130 is mounted on the bottom surface of the tank body 10. The support boss 130 provides support for the tank body 10, and can reliably and conveniently place the tank body 10 flat in a predetermined position, preventing the resin tank from tipping over. As an example, Figure 6 The diagram shows a preferred structure of the support boss 130.
[0094] The following is a brief description of the process of resin regeneration and soft water output using the resin tank in this embodiment.
[0095] When resin regeneration is required, the solenoid valves at the brine inlet 20 and wastewater outlet 40 open, allowing concentrated brine to flow from the brine inlet 20 into the guide pipe 80. From there, the brine flows into the second receiving cavity 104 below the distributor seat 60. This concentrated brine then slowly disperses from the bottom of the tank body 10 to the top of the resin through the second connecting hole 701 on the distributor column 70 and the first connecting hole 601 on the distributor seat 60. The replaced wastewater slowly flows out through the wastewater outlet. Once the regeneration reaches the system's preset time, the solenoid valves at the brine inlet 20 and wastewater outlet 40 close.
[0096] When soft water needs to be used normally and soft water is dispensed, the solenoid valves at the raw water inlet 30 and the soft water outlet 50 are opened. Raw water flows into the tank body 10 from the top of the tank body 10 through the raw water inlet 30. In the first accommodating cavity 103, the raw water is softened by the resin, and the softened soft water flows out from the soft water outlet 50.
[0097] For water softeners, the resin regeneration process and the soft water output process can be carried out in a cycle according to the system's preset time.
[0098] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
