[0052] Embodiment one

[0053] The existing water softener usually has a softening tank and a softening valve arranged in the box body. The softening tank contains resin, and the softening valve is arranged at the top of the softening tank, so as to adjust the flow direction of water in the water softener through the softening valve. However, by arranging the softening valve at the top of the softening tank, the softening valve will occupy the space at the top of the softening tank. If the height of the entire water softener is to be ensured, the extension height of the softening tank is greatly reduced, and thus the filling amount of resin in the softening tank is reduced, and the softening effect of the softening tank on water is reduced.

[0054] In order to solve the above problems, as shown in Figure 1 and Figure 2 , the present embodiment provides a water softener, which comprises a box body 1, a softening tank 2, an adapter pipe assembly 3 and a softening valve 4. The softening tank 2, the adapter pipe assembly 3 and the softening valve 4 are all arranged in the box body 1. The adapter pipe assembly 3 is in communication with the softening tank 2. The softening valve 4 is in communication with the adapter pipe assembly 3. The softening valve 4 is configured to adjust the flow direction of water in the adapter pipe assembly 3. The softening valve 4 is located on one side of the softening tank 2 in the first radial direction (front-rear direction in the figure). The water softener provided by the present embodiment effectively avoids the softening valve 4 occupying the space at the top of the softening tank 2 in the box body 1, so as to fully utilize the space in the box body 1, effectively increase the extension height of the softening tank 2, improve the filling amount of resin in the softening tank 2, and improve the softening effect of the softening tank 2 on water.

[0055] It should be noted that the radial direction of the softening tank 2 refers to each direction of the outer circumferential side of the softening tank 2. Alternatively, in the present embodiment, as shown in Figure 2 , the softening valve 4 is arranged at the rear side of the softening tank 2. In other embodiments, the softening valve 4 can also be arranged at the front side, left side, right side or other side positions of the softening tank 2. The present application does not specifically limit the arrangement position of the softening valve 4, as long as the softening valve 4 is arranged at the outer circumferential side of the softening tank 2. Alternatively, in the present embodiment, the softening tank 2 extends along the vertical direction (up-down direction in the figure).

[0056] In the present embodiment, as shown in 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 communicated with the first outlet 42, the second inlet 43 is communicated with the second outlet 44, the top of the softening tank 2 is provided with an adapter pipe assembly 3, the adapter pipe assembly 3 comprises an output pipeline 33 and a return pipeline 34, the output pipeline 33 is communicated with the first outlet 42, and the softening tank 2 is communicated with the output pipeline 33, the return pipeline 34 is communicated with the softening tank 2, and the return pipeline 34 is communicated with the second inlet 43. The above arrangement makes the raw water enter the first inlet 41 of the softening valve 4, then enter the first outlet 42, then enter the output pipeline 33 through the first outlet 42, and then enter the softening tank 2 through the output pipeline 33. The raw water is converted into soft water in the softening tank 2 after being filtered by the resin, and then flows into the return pipeline 34 through the central pipe in the softening tank 2. Finally, the soft water in the return pipeline 34 flows out through the second inlet 43 and the second outlet 44 of the softening valve 4 in turn, so as to complete the preparation of soft water.

[0057] It should be noted that "the top of the softening tank 2" refers to the position of the top of the softening tank 2, and "the top of the softening tank 2 is provided with the adapter pipe assembly 3" means that the adapter pipe assembly 3 is arranged at the top position of the softening tank 2. The height of the position of the adapter pipe assembly 3 can be higher than the top of the softening tank 2, or the height of the position of the adapter pipe assembly 3 can be not higher than the top of the softening tank 2.

The above arrangement of the positions of the first inlet 41 and the second outlet 44 occupies the idle installation space below the softening tank 2, improves the space utilization rate in the cabinet 1, facilitates saving the installation space, and facilitates the communication of the first inlet 41 and the second outlet 44 with the pipeline at the rear side of the cabinet 1, so as to make the layout more reasonable.

[0060] In the embodiment, as shown in the figure, Figure 2 the first outlet 42 and the second inlet 43 are both located on the side of the softening valve 4 close to the softening tank 2 (i.e. the first outlet 42 and the second inlet 43 are both located on the front side of the softening valve 4). The above arrangement facilitates the communication of the first outlet 42 with the output pipeline 33, and facilitates the communication of the second inlet 43 with the return pipeline 34.

The above arrangement makes the arrangement of the softening valve 4 and the softening tank 2 more compact, thereby saving the space in the box 1 along the front-back direction. Optionally, in other embodiments, the first outlet 42 and the second inlet 43 can 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 more compact.

The structural design of the above-mentioned output pipeline 33 makes the structure of the output pipeline 33 more compact and the layout more reasonable. Optionally, in the present embodiment, the output elbow 331 is located between the softening tank 2 and the softening valve 4.

[0063] Optionally, in the present embodiment, as shown in Figure 2 the return pipeline 34 includes a return straight pipe 341 and a return elbow 342 connected in communication, wherein the return straight pipe 341 is in communication with the softening tank 2, the return elbow 342 is in communication with the second inlet 43, the return straight pipe 341 is located at the top of the softening tank 2, and the return straight pipe 341 extends along the front-back direction, and the soft water discharged from the softening tank 2 passes into the second inlet 43 in sequence through the return straight pipe 341 and the return elbow 342.

[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 softening valve 4 is located in front of the front softening tank 2.

Through the water inlet pipe 31 and the water outlet pipe 32, the above-mentioned arrangement facilitates the passage of external raw water that needs to be softened into the first inlet 41 through the water inlet pipe 31, and also facilitates the discharge of softened water discharged from the second outlet 44 through the water outlet pipe 32. In addition, the arrangement of the water outlet pipe 32, the water inlet pipe 31, the output pipe 33 and the backflow pipe 34 makes each pipe arranged in the left-right direction at the top of the softening tank 2 in turn, avoiding the stacking of each pipe in the up-down direction at the top of the softening tank 2, reducing the space occupied by the adapter pipe assembly 3 at the top of the softening tank 2, and effectively ensuring the extension height of the softening tank 2.

[0077] Optionally, in the present embodiment, the output pipe 33 and the backflow pipe 34 are both located between the water inlet pipe 31 and the water outlet pipe 32. The above-mentioned arrangement makes the output pipe 33 and the backflow pipe 34 as close as possible to the softening tank 2 for communication, thereby reducing the flow path of the output pipe 33 and the backflow pipe 34, making the structure more compact and reasonable, and also ensuring the softening effect.
