[0057] The utility model will be described below in a preferred embodiment, and in combination with the drawings to be more clear and complete.

[0058] As Figure 1 and Figure 2 shown, the embodiment discloses a purified water and soft water integrated equipment, which integrates the functions of a purified water machine and a soft water machine.

[0059] As Figure 1 and Figure 2As shown, the integrated water purification and softening equipment includes valve 1, water purification module 2, water softening module 3, raw water inlet pipe 4, purified water outlet pipe 5, softened water outlet pipe 6, first sewage outlet pipe 7, and second sewage outlet pipe 8.

[0060] like Figure 1 and Figure 2 As shown, valve 1 includes a valve body and a valve core (not shown in the figure). The valve core can move relative to the valve body to regulate the opening and closing of each water path in the integrated water purification and softening equipment, allowing the equipment to switch between a water usage mode and a flushing mode. The water usage mode refers to the mode in which water-using devices such as faucets can dispense water normally. The flushing mode is a mode for cleaning the purification structure in the water purification module 2 to improve its service life; in this mode, water-using devices do not dispense water. This embodiment adjusts the operating mode of the integrated water purification and softening equipment by controlling the valve core, resulting in a simple structure and smaller footprint.

[0061] Specifically, such as Figure 1 and Figure 2 As shown, valve 1 has a first raw water inlet 11, a raw water outlet 12, a first purified water inlet 13, a first purified water outlet 14, a second purified water outlet 15, a sewage inlet 16, and a first sewage outlet 17. Water purification module 2 includes a second raw water inlet 21, a third purified water outlet 22, and a second sewage outlet 23. Soft water module 3 includes a second purified water inlet 31, a soft water outlet 32, and a third sewage outlet 33.

[0062] In water usage mode, the first raw water inlet 11 is connected to the raw water inlet pipe 4, which introduces water from the first raw water inlet 11 into the integrated water purification and softening equipment. The first raw water inlet 11 is connected to the raw water outlet 12, which is connected to the second raw water inlet 21. Valve 1 guides the raw water through the raw water outlet 12 to the water purification module 2 for purification. Both the second raw water inlet 21 and the first purified water inlet 13 are connected to the third purified water outlet 22. After purification by the water purification module 2, the purified water flows out of the water purification module 2 through the third purified water outlet 22 and into valve 1 through the first purified water inlet 13. The first purified water outlet 14 and the second purified water outlet 15 are both connected to the first purified water inlet 13. The first purified water outlet 14 is connected to the purified water outlet pipe 5. The second purified water outlet 15 is connected to the second purified water inlet 31. The second purified water inlet 31 is connected to the soft water outlet 32. Through the distribution of valve 1, the purified water flows to the purified water outlet pipe and the soft water module 3 respectively. The soft water outlet 32 ​​is connected to the soft water outlet pipe 6. The soft water formed after treatment by the soft water module 3 is supplied to the water-using equipment through the soft water outlet pipe. The second raw water inlet 21, the third purified water outlet 22, and the sewage inlet 16 are all connected to the second sewage outlet 23. The first sewage outlet 17 is connected to the first sewage outlet pipe 7, which is used to discharge the sewage generated when the purified water module 2 is working. The third sewage outlet 33 is connected to the second sewage outlet pipe 8, which is used to discharge the sewage generated when the soft water module 3 is working.

[0063] This embodiment integrates the functions of existing water purifiers and water softeners into one device. The water purification and softening operations are controlled simultaneously through valve 1. Compared with separate water purifiers and water softeners, the overall size of the device is smaller, reducing the space occupied by the device.

[0064] like Figure 1 As shown, the water purification module 2 includes a filter element 24, which is the purification structure in the water purification module 2. The inlet of the filter element 24 forms a second raw water inlet 21, the purified water outlet of the filter element 24 forms a third purified water outlet 22, and the sewage outlet of the filter element 24 forms a second sewage outlet 23.

[0065] In this embodiment, the filter element 24 is a hollow fiber membrane filter element 24, which has good chemical resistance and a longer service life. Preferably, the filter element 24 is an internal pressure hollow fiber membrane filter element 24, which has a larger filtration gap and is easily cleaned by water flow in the flushing mode, thereby extending its service life.

[0066] In other alternative embodiments, the filter element 24 may also be an external pressure hollow fiber membrane filter element 24 or other forms of filtration structure.

[0067] Further, as shown in Figure 2 The number of filter cartridges 24 in the embodiment is two. In the water use mode, the two filter cartridges 24 are connected in parallel, that is, the water paths through the two filter cartridges 24 are independent of each other in the water use mode. The purified water produced by any one filter cartridge 24 directly flows to the valve 1 and does not flow to the other filter cartridge 24, thereby improving the working efficiency of the purified water module 2 and meeting the demand of the purified water and soft water integrated device for a large water flow.

[0068] In other alternative embodiments, the number of filter cartridges 24 can also be one or more.

[0069] Further, the flushing mode in the embodiment includes a forward flushing mode and a reverse flushing mode.

[0070] Specifically, as shown in Figure 3 In the forward flushing mode, the first raw water inlet 11, the raw water outlet 12, the sewage inlet 16, and the first sewage outlet 17 are in an open state, the first purified water inlet 13 is in a closed state, and the first raw water inlet 11 is in communication with the raw water outlet 12. The water flow flows out of the raw water outlet 12 of the valve 1, enters the filter cartridge 24 from the second raw water inlet 21 of the purified water module 2 to flush the filter cartridge 24, the waste water produced by the flushing is discharged from the filter cartridge 24 through the second sewage outlet 23, and then discharged from the first sewage outlet pipeline 7 of the valve 1 to the purified water and soft water integrated device.

[0071] As shown in Figure 4 The flushing mode includes a reverse flushing mode. In the reverse flushing mode, the first raw water inlet 11, the first purified water inlet 13, the sewage inlet 16, and the first sewage outlet 17 are in an open state, the raw water outlet 12 is in a closed state, and the first raw water inlet 11 is in communication with the first purified water inlet 13. The water flow flows out of the first purified water inlet 13 of the valve 1, enters the filter cartridge 24 from the third purified water outlet 22 of the purified water module 2 to flush the filter cartridge 24, the waste water produced by the flushing is discharged from the filter cartridge 24 through the second sewage outlet 23, and then discharged from the first sewage outlet pipeline 7 of the valve 1 to the purified water and soft water integrated device.

[0072] The embodiment cleans the filter cartridge 24 by flushing the filter cartridge 24 with water flow, so as to improve the service life of the filter cartridge 24.

[0073] In other alternative embodiments, the purified water and soft water integrated device can also be designed only with the forward flushing mode or only with the reverse flushing mode to flush the filter cartridge 24.

[0074] Further, as shown in Figure 3 and Figure 4As shown, in the flushing mode (both forward flushing mode and back flushing mode), two filter cartridges 24 are connected in series, that is, raw water first enters one filter cartridge 24 to flush it, and the purified water produced by the filter cartridge 24 under the flushing of the raw water can flow into the next filter cartridge 24 to flush the next filter cartridge 24, and the purified water produced by the next filter cartridge 24 after being flushed can also flow back to the previous filter cartridge 24 to flush it. The two filter cartridges 24 flush each other, so that the filter cartridges 24 are cleaned more thoroughly.

[0075] In other alternative embodiments, if the number of filter cartridges 24 is more, the plurality of filter cartridges 24 can be connected in series in turn, that is, raw water flushes the first filter cartridge 24, the purified water produced by the first filter cartridge 24 flushes the second filter cartridge 24, the purified water produced by the second filter cartridge 24 flushes the third filter cartridge, and so on. Alternatively, in order to improve the flushing efficiency, an even number of filter cartridges 24 can be provided, the even number of filter cartridges 24 are divided into a plurality of filter cartridge groups, each filter cartridge group includes two filter cartridge units, the two filter cartridge units in the same filter cartridge group are connected in series and include the same number of filter cartridges 24, and the plurality of filter cartridges 24 in the same filter cartridge unit are connected in parallel, so as to ensure that the water passing through the two filter cartridge units in the same filter cartridge group is substantially the same, and the flushing effect is ensured.

[0076] In addition, before the water purification and water softening integrated device is used for the first time, it can be first flushed with power to clean impurities and ensure water quality. Specifically, after the water purification and water softening integrated device is powered on for the first time, the first raw water inlet 11 and the raw water outlet 12 of the valve 1 are communicated, raw water flows to the water purification module 2 through the raw water outlet 12, and purified water generated by the water purification module 2 after being treated by the raw water flows to the valve 1 from the third purified water outlet 22. The valve 1 divides the purified water into two paths, one of which flows to the first purified water outlet 14, and the other of which flows to the second purified water outlet 15. The water flow flowing to the first purified water outlet 14 can be continuously discharged for a period of time through the water using device, and the specific time can be designed according to the actual situation, for example, for fifteen minutes. The water flowing to the second purified water outlet 15 flows into the water softening module 3, and after being treated by the water softening module 3, the water flow appearing at the water softening outlet 32 of the water softening module 3 can be closed first, and the power flushing is ended after the water flow flowing to the first purified water outlet 14 is discharged for a period of time that meets the requirements.
