Description

Technical Field

[0001] This invention relates to the field of water treatment technology, and more particularly to a water softener. Background Technology

[0002] Water softeners primarily remove calcium and magnesium ions from water using resin, reducing water hardness and thus softening the water to solve problems such as limescale and blockages. Existing water softeners typically contain a softening tank and a softening valve within the casing. The softening tank is filled with resin, and the softening valve is located at the top of the tank to regulate water flow. However, placing the softening valve at the top of the tank occupies space above it. To maintain the overall height of the water softener, this significantly reduces the overall height of the softening tank, consequently reducing the amount of resin inside and thus decreasing the softening effect.

[0003] Therefore, there is an urgent need for a water softener to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a water softener that makes full use of the space inside the water softener's casing, effectively increases the extension height of the softening tank, increases the amount of resin filling the softening tank, and improves the softening effect of the softening tank on water.

[0052] Example 1

[0053] Existing water softeners typically contain a softening tank and a softening valve within the casing. The softening tank is filled with resin, and the softening valve is located at the top of the tank to regulate the water flow. However, placing the softening valve at the top of the tank occupies space above it. To maintain the overall height of the water softener, this significantly reduces the overall height of the softening tank, thereby reducing the amount of resin inside and diminishing its water softening effect.

[0054] To solve the above problems, such as Figure 1 and Figure 2 As shown, this embodiment provides a water softener, which includes a housing 1, a softening tank 2, a connecting pipe assembly 3, and a softening valve 4. The softening tank 2, the connecting pipe assembly 3, and the softening valve 4 are all housed within the housing 1. The connecting pipe assembly 3 communicates with the softening tank 2, and the softening valve 4 communicates with the connecting pipe assembly 3. The softening valve 4 is configured to regulate the flow direction of water within the connecting pipe assembly 3, and is located on one side of the softening tank 2 in the first radial direction (front-back direction in the figure). By placing the softening valve 4 on one side of the softening tank 2 in the first radial direction, this embodiment effectively avoids the softening valve 4 occupying the space at the top of the softening tank 2 within the housing 1, thereby fully utilizing the space within the housing 1, effectively increasing the extension height of the softening tank 2, increasing the resin filling amount within the softening tank 2, and improving the water softening effect of the softening tank 2.

[0055] It should be noted that the radial direction of the softening tank 2 refers to all directions along the outer periphery of the softening tank 2. Optionally, in this embodiment, as... Figure 2 As shown, the softening valve 4 is located on the rear side of the softening tank 2. In other embodiments, the softening valve 4 may also be located on the front, left, right, or other side of the softening tank 2. This application does not specifically limit the location of the softening valve 4, as long as it is located on the outer periphery of the softening tank 2. Optionally, in this embodiment, the softening tank 2 extends in a vertical direction (up and down direction in the figure).

[0056] In this embodiment, as Figure 2As shown, the softening valve 4 is provided with a first inlet 41, a first outlet 42, a second inlet 43, and a second outlet 44. The first inlet 41 is connected to the first outlet 42, and the second inlet 43 is connected to the second outlet 44. The top of the softening tank 2 is provided with a transfer pipe assembly 3, which includes an output pipe 33 and a return pipe 34. The output pipe 33 is connected to the first outlet 42, and the softening tank 2 is connected to the output pipe 33. The return pipe 34 is connected to the softening tank 2, and the return pipe 34 is connected to the second inlet 43. The above configuration allows raw water to be introduced into the first inlet 41 of the softening valve 4, then into the first outlet 42, and then into the output pipe 33. The raw water is then introduced into the softening tank 2 through the resin filtration in the softening tank 2, where it is converted into soft water. The soft water is then discharged into the return pipe 34 through the central pipe in the softening tank 2. Finally, the soft water in the return pipe 34 flows out after passing through the second inlet 43 and the second outlet 44 of the softening valve 4, thus completing the preparation of soft water.

[0057] It should be noted that "the top of softening tank 2" refers to the top position of softening tank 2, and "the top of softening tank 2 is provided with a transfer pipe assembly 3" means that a transfer pipe assembly 3 is provided at the top position of softening tank 2. The height of the transfer pipe assembly 3 can be higher than the top of softening tank 2, or the height of the transfer pipe assembly 3 can be no higher than the top of softening tank 2.

[0058] Optionally, in this embodiment, the first outlet 42 and the second inlet 43 are arranged at intervals. Optionally, in other embodiments, the first outlet 42 and the second inlet 43 may also be arranged coaxially, thereby making the structure more compact.

[0059] Optionally, in this embodiment, both the first inlet 41 and the second outlet 44 are located below the softening valve 4, and both the first inlet 41 and the second outlet 44 extend towards the softening valve 4 away from the softening tank 2 (i.e., both the first inlet 41 and the second outlet 44 extend towards the rear side as shown in the figure). The aforementioned positioning of the first inlet 41 and the second outlet 44 occupies the empty installation space below the softening tank 2, improving the space utilization rate within the housing 1, saving installation space, and facilitating the connection of the first inlet 41 and the second outlet 44 with the pipelines on the rear side of the housing 1, resulting in a more rational layout.

[0060] In this embodiment, as Figure 2 As shown, the first outlet 42 and the second inlet 43 are both located on the side of the softening valve 4 closest to the softening tank 2 (i.e., the first outlet 42 and the second inlet 43 are both located in front of the softening valve 4). This arrangement facilitates the connection of the first outlet 42 to the output pipeline 33 and the second inlet 43 to the return pipeline 34.

[0061] Optionally, in other embodiments, the first outlet 42 and the second inlet 43 are both located on the same side of the softening valve 4 along the second radial direction (left-right direction in the figure) of the softening tank 2, wherein the first radial direction and the second radial direction of the softening tank 2 are perpendicular to each other. This arrangement allows for a more compact arrangement of the softening valve 4 and the softening tank 2, thereby saving space within the housing 1 along the front-back direction. Optionally, in other embodiments, the first outlet 42 and the second inlet 43 may also be located on opposite sides of the softening valve 4 along the second radial direction of the softening tank 2, thereby making the arrangement of the softening valve 4 and the softening tank 2 even more compact.

[0062] Optionally, in this embodiment, as Figure 2 As shown, the output pipeline 33 includes an output bend 331 and an output straight pipe 334 connected to each other. The output bend 331 is connected to the first outlet 42, and the output straight pipe 334 is connected to the softening tank 2. The output straight pipe 334 is located at the top of the softening tank 2 and extends in the front-to-back direction. The raw water discharged from the first outlet 42 passes through the output bend 331 and the output straight pipe 334 in sequence before entering the softening tank 2. The above-mentioned structural design of the output pipeline 33 makes the structure of the output pipeline 33 more compact and the layout more reasonable. Optionally, in this embodiment, the output bend 331 is located between the softening tank 2 and the softening valve 4.

[0063] Optionally, in this embodiment, as Figure 2 As shown, the return pipeline 34 includes a straight return pipe 341 and a return bend 342 connected to each other. The straight return pipe 341 is connected to the softening tank 2, and the return bend 342 is connected to the second inlet 43. The straight return pipe 341 is located at the top of the softening tank 2 and extends in the front-to-back direction. The softened water discharged from the softening tank 2 passes through the straight return pipe 341 and the return bend 342 in sequence before entering the second inlet 43. The above-mentioned structural design of the return pipeline 34 makes the structure of the return pipeline 34 more compact and the layout more reasonable. Optionally, in this embodiment, the return bend 342 is located between the softening tank 2 and the softening valve 4.

[0064] Optionally, in this embodiment, as Figure 2 As shown, the water softener also includes a brine tank 6, which is connected to the tank body 1. The brine suction pipe in the brine tank 6 is connected to the softening tank 2, thereby providing sodium ions through the brine tank 6. These sodium ions exchange with calcium and magnesium ions in the resin of the softening tank 2, displacing the calcium and magnesium ions and restoring the resin's function of softening water. Optionally, in this embodiment, the brine suction pipe in the brine tank 6 can be connected to the softening tank 2 via a softening valve 4 and a transfer pipe assembly 3.

[0065] Optionally, in this embodiment, as Figure 2As shown, the salt tank 6 is located at the bottom of the tank 1, and the salt tank 6 is located on the side of the softening tank 2 away from the softening valve 4 (i.e., on the front side of the softening tank 2). The above-mentioned layout of the salt tank 6 can make full use of the empty space at the bottom and front of the tank 1, improve the space utilization of the tank 1, save installation space, and make the layout more reasonable.

[0066] Example 2

[0067] The water softener provided in this embodiment is basically the same as that in Embodiment 1. The difference between the water softener provided in this embodiment and that in Embodiment 1 is as follows:

[0068] like Figure 3 As shown, in this embodiment, the water softener includes two softening tanks 2 arranged at intervals, and the two softening tanks 2 are connected in series via a connecting pipe assembly 3. By setting two softening tanks 2 connected in series, the softening effect on the raw water is effectively improved. Optionally, in this embodiment, the two softening tanks 2 are arranged at intervals in a front-to-back direction. Optionally, in this embodiment, the softening valve 4 is located behind the rear softening tank 2.

[0069] Optionally, in this embodiment, as Figure 3 As shown, the return pipe 34 includes a first return pipe 343 and a second return pipe 344. The output straight pipe 334 is connected to the softening tank 2 located at the front. One end of the first return pipe 343 is connected to the softening tank 2 located at the front, and the other end of the first return pipe 343 is connected to the softening tank 2 located at the rear. One end of the second return pipe 344 is connected to the softening tank 2 located at the rear, and the other end of the second return pipe 344 is connected to the second inlet 43. The above configuration allows raw water to be introduced into the first inlet 41 of the softening valve 4, then into the first outlet 42, and then into the output pipe 33. The water then flows through the straight output pipe 334 of the output pipe 33 into the softening tank 2 located at the front. After primary filtration by the resin in the softening tank 2, the raw water is discharged through the central pipe of the softening tank 2 into the first return pipe 343, and then through the first return pipe 343 into the rear softening tank 2. The primary filtered raw water undergoes further filtration in the rear softening tank 2, and then flows through the central pipe of the softening tank 2 into the second return pipe 344. Finally, the softened water in the second return pipe 344 flows out after passing through the second inlet 43 and the second outlet 44 of the softening valve 4, thus completing the preparation of softened water.

[0070] Optionally, in other embodiments, the incoming raw water may first flow through the softening tank 2 located at the rear, and then through the softening tank 2 located at the front. This application does not limit the flow order of the two softening tanks 2. Optionally, in other embodiments, the number of softening tanks 2 can also be set according to needs.

[0071] Example 3

[0072] The water softener provided in this embodiment is basically the same as that in Embodiment 1. The difference between the water softener provided in this embodiment and that in Embodiment 1 is as follows:

[0073] like Figures 4-6 As shown, in this embodiment, the softening valve 4 is disposed on the front side of the softening tank 2. In other embodiments, the softening valve 4 may also be disposed on the rear, left, right, or other side of the softening tank 2. This application does not specifically limit the placement of the softening valve 4, as long as it is disposed on the outer periphery of the softening tank 2.

[0074] Optionally, such as Figure 5 and Figure 6 As shown, in this embodiment, the water softener includes two softening tanks 2 arranged at intervals, and the two softening tanks 2 are connected in series via a connecting pipe assembly 3. By setting two softening tanks 2 connected in series, the softening effect on the raw water is effectively improved. Optionally, in this embodiment, the two softening tanks 2 are arranged at intervals in a front-to-back direction. Optionally, in this embodiment, the softening valve 4 is located in front of the front softening tank 2.

[0075] Optionally, in this embodiment, as Figure 4 and Figure 5 As shown, the salt tank 6 includes a first salt tank body 61 and a second salt tank body 62. At least one of the first salt tank body 61 and the second salt tank body 62 is connected to the tank body 1. The connection between the first salt tank body 61 and the second salt tank body 62 is L-shaped. The first salt tank body 61 is located below the softening valve 4, and the second salt tank body 62 is located on the side of the softening valve 4 away from the softening tank 2 (i.e., in front of the softening valve 4). The above-described structural design of the salt tank 6 can fully utilize the empty space below and in front of the softening valve 4, effectively increasing the volume of the salt tank 6. Optionally, in this embodiment, both the first salt tank body 61 and the second salt tank body 62 are connected to the tank body 1, thereby ensuring the stability and reliability of the connection between the salt tank 6 and the tank body 1.

[0076] Optionally, in this embodiment, as Figure 5 and Figure 6As shown, the transfer pipe assembly 3 also includes an inlet pipe 31 and an outlet pipe 32. The inlet pipe 31 is connected to the first inlet 41, and the outlet pipe 32 is connected to the second outlet 44. The outlet pipe 32, the inlet pipe 31, the outlet pipe 33, and the return pipe 34 are arranged at intervals along the second radial direction (left-right direction in the figure) of the softening tank 2 at the top. This arrangement facilitates the introduction of softened raw water from the outside into the first inlet 41 through the inlet pipe 31, and also facilitates the discharge of softened water from the second outlet 44 through the outlet pipe 32. In addition, the arrangement of the above-mentioned outlet pipe 32, inlet pipe 31, output pipe 33 and return pipe 34 allows each pipe to be arranged sequentially in the left-right direction on the top of the softening tank 2, avoiding the stacking of each pipe in the up-down direction on the top of the softening tank 2, reducing the space occupied by the transfer pipe assembly 3 on the top of the softening tank 2, and effectively ensuring the extension height of the softening tank 2.

[0077] Optionally, in this embodiment, both the output pipe 33 and the return pipe 34 are located between the inlet pipe 31 and the outlet pipe 32. This arrangement brings the output pipe 33 and the return pipe 34 as close as possible to the softening tank 2, thereby reducing the flow path of the output pipe 33 and the return pipe 34, resulting in a more compact and reasonable structure, and ensuring the softening effect.

[0078] Optionally, in this embodiment, as Figure 6As shown, the water inlet pipe 31 includes a first water inlet pipe section 311, a second water inlet pipe section 312, and a third water inlet pipe section 313 connected at an angle in sequence. The first water inlet pipe section 311 extends along the first radial direction of the softening tank 2, the second water inlet pipe section 312 extends along the second radial direction of the softening tank 2, and the third water inlet pipe section 313 extends along the axial direction (up and down direction in the figure) of the softening tank 2. The third water inlet pipe section 313 is connected to the first inlet 41. The water outlet pipe 32 includes a first water inlet pipe section 311 connected at an angle in sequence. The softening tank 2 is equipped with a first outlet pipe section 321, a second outlet pipe section 322, and a third outlet pipe section 323. The first outlet pipe section 321 extends along the first radial direction of the softening tank 2. The first inlet pipe section 311 and the first outlet pipe section 321 are arranged at intervals along the second radial direction of the softening tank 2 at the top of the softening tank 2. The second outlet pipe section 322 extends along the second radial direction of the softening tank 2. The third outlet pipe section 323 extends along the axial direction of the softening tank 2 and is connected to the second outlet 44. This arrangement allows raw water from the outside to sequentially enter the first inlet 41 through the first inlet pipe section 311, the second inlet pipe section 312, and the third inlet pipe section 313. Softened water discharged from the second outlet 44 is then sequentially discharged through the third outlet pipe section 323, the second outlet pipe section 322, and the first outlet pipe section 321. Optionally, in this embodiment, the first inlet 41 and the second outlet 44 are both located at the top of the softening valve 4, which facilitates the connection of the first inlet 41 to the third inlet pipe section 313 and the connection of the second outlet 44 to the third outlet pipe section 323.

[0079] Optionally, in this embodiment, as Figure 6As shown, the return pipe 34 is connected to the output pipe 33. Specifically, the output pipe 33 includes an output bend 331, a first connector 332, and a second connector 333 connected in sequence. The return pipe 34 includes a return straight pipe 341 and a return bend 342 connected in sequence. The output bend 331 is connected to the first outlet 42. The first connector 332 and the second connector 333 are both located at the top of the softening tank 2. The first connector 332 is connected to the softening tank 2 located at the front, and the second connector 333 is connected to the softening tank 2 located at the rear. The return straight pipe 341 is located at the top of the softening tank 2 and extends in the front-to-back direction. The return straight pipe 341 is connected to the second connector 333, and the return bend 342 is connected to the second inlet 43. The above configuration allows raw water to be introduced into the first inlet pipe section 311, then sequentially through the second inlet pipe section 312, the third inlet pipe section 313, the first inlet 41, and the first outlet 42 into the outlet bend 331. The raw water then flows through the first connector 332 into the softening tank 2 located at the front. After primary filtration by resin in the softening tank 2, the raw water is discharged through the central pipe of the softening tank 2 into the first connector 332, and then through the second... Connector 333 is connected to the softening tank 2 on the rear side. The raw water after primary filtration is filtered again in the softening tank 2 on the rear side, and then discharged into the second connector 333 through the central pipe in the softening tank 2. Then, it is discharged into the third outlet pipe section 323 through the return straight pipe 341, the return bend pipe 342, the second inlet 43 and the second outlet 44 in sequence. Then, it is discharged through the second outlet pipe section 322 and the first outlet pipe section 321 in sequence to complete the preparation of soft water.

[0080] Optionally, in other embodiments, the incoming raw water may first flow through the softening tank 2 located at the rear, and then through the softening tank 2 located at the front. This application does not limit the flow order of the two softening tanks 2. Optionally, in other embodiments, the number of softening tanks 2 can also be set according to needs.

[0081] Optionally, in this embodiment, as Figure 4 and Figure 6 As shown, the water softener also includes a connector assembly 5, which includes an inlet pipe connector 51 and an outlet pipe connector 52. Both the inlet pipe connector 51 and the outlet pipe connector 52 are housed within the housing 1. The inlet pipe connector 51 is connected to the inlet end of the inlet pipe 31 (i.e., the first inlet pipe section 311), and the outlet pipe connector 52 is connected to the outlet end of the outlet pipe 32 (i.e., the first outlet pipe section 321). This arrangement, by housing both the inlet pipe connector 51 and the outlet pipe connector 52 within the unused space of the housing 1, improves the space utilization within the housing 1 and avoids the inlet pipe connector 51 and the outlet pipe connector 52 occupying additional space outside the housing 1.

[0082] Optionally, in this embodiment, both the inlet pipe connector 51 and the first inlet pipe section 311 extend along the first radial direction of the softening tank 2, and the inlet pipe connector 51 is located on the side of the first inlet pipe section 311 near the outlet end of the outlet pipe 32. Similarly, both the outlet pipe connector 52 and the first outlet pipe section 321 extend along the first radial direction of the softening tank 2, and the outlet pipe connector 52 is located on the side of the first outlet pipe section 321 near the inlet end of the inlet pipe 31. This arrangement allows the inlet pipe connector 51 and the first inlet pipe section 311 to be staggered, and the outlet pipe connector 52 and the first outlet pipe section 321 to be staggered, thereby fully utilizing the unused space between the first inlet pipe section 311 and the first outlet pipe section 321, resulting in a more compact and rational structure.

[0083] Optionally, in this embodiment, the connector assembly 5 further includes a connector connecting plate 53, on which the inlet pipe connector 51 and the outlet pipe connector 52 are both mounted, and the connector connecting plate 53 is detachably mounted on the housing 1. This configuration makes the connector assembly 5 modular, facilitating the installation of the entire connector assembly 5 on the housing 1.
