[0052] Example 1

[0053] In a specific embodiment of the present disclosure, a clean soft waterway system is provided, such as Figure 1 As shown, the clean and soft water system includes a controller (not shown in the figure), a softening device 1, a water purification device 2 and a salt making device 3;

[0054] The wastewater outlet of the water purification device 2 is connected to the first water inlet of the salt making device 3 through the first pipeline;

[0055] The salt absorption port of the water softening device 1 is connected to the salt making device 3 through the salt absorption pipe;

[0056] The water inlet of the water softener 1 and the water inlet of the water purifier 2 are both used to receive raw water;

[0057] The water purification device 2 is used to purify the raw water to obtain treated wastewater, and the wastewater flows into the salt making device 3 through the first pipeline to form a salt solution;

[0058] The controller is used to drive the softening device 1 to absorb salt solution from the salt making device 3 through the salt absorption pipe in the soft water regeneration mode, so as to soften the raw water to generate soft water, and then flow out through the soft water outlet.

[0059] Specifically, after the water purifier 2 purifies the raw water, it will also produce waste water while obtaining the purified water, and the water softener 1 (such as a water softener) needs to regularly add salt (sodium chloride) to combine with the calcium and magnesium ions in the water to reduce the hardness of the water and achieve the purpose of softening the water. Therefore, by storing the waste water generated by the water purifier 2 during the purification process in the salt making device 3 (such as a salt tank), the salt in the salt making device 3 is dissolved to form a salt solution. When the soft water usage reaches the water production amount, it will trigger the soft water regeneration mode. The controller drives the water softener 1 to absorb the salt solution from the salt making device 3 through the salt absorption pipe of the salt absorption port, so that the sodium chloride in the salt solution is fully replaced with the calcium and magnesium ions of the resin to generate soft water to flow out through the soft water port for users to use. As for the replaced calcium and magnesium ions, they can be discharged through the sewage outlet 1.

[0060] In this specific embodiment, the water purification device 2 and the water softening device 1 are centrally controlled, and the wastewater generated by the water purification device 2 during the purification process is stored in the salt making device 3 to form a salt solution that can be used by the water softening device 1, thereby realizing the reuse of the wastewater.

[0061] In a specific embodiment, Figure 1 As shown, a wastewater solenoid valve 11 and a first solenoid valve 12 are sequentially provided on the first pipeline along the wastewater flow direction;

[0062] The salt making device 3 is provided with a first liquid level detection element 13, and the first liquid level detection element 13 is used to detect a first liquid level signal corresponding to a first liquid level of the salt solution;

[0063] The controller is also used to, in the soft water regeneration mode, in response to not receiving the first liquid level signal, drive the water purification device 2 to purify the raw water, and drive the wastewater solenoid valve 11 and the first solenoid valve 12 to open so that the treated wastewater flows into the salt making device 3 through the first pipeline, and / or, in response to receiving the first liquid level signal, drive the water softening device 1 to absorb salt solution from the salt making device 3 through the salt absorption pipe to soften the raw water to generate soft water, and flow out through the soft water outlet.

[0064] Specifically, a first liquid level detection member 13, such as a liquid level float, may be provided in the salt making device 3 to detect the liquid level of the salt solution in the salt making device 3. If the liquid level of the salt solution is detected in the soft water regeneration mode, the water softening device 1 may directly absorb salt from the salt making device 3 through the salt absorption pipe to soften the raw water to form soft water; and if the liquid level of the salt solution is not detected, the water purification device 2 is driven to purify the raw water, and the waste water solenoid valve 11 and the first solenoid valve 12 are driven to open, so that the waste water generated by the water purification device 2 during the purification process flows into the salt making device 3 to form a salt solution. After the liquid level float detects the liquid level of the salt solution, the water purification device 2, the waste water solenoid valve 11 and the first solenoid valve 12 are driven to close, and then the water softening device 1 is driven to absorb salt to generate soft water.

[0065] In a specific embodiment, Figure 2 As shown, the clean and soft water circuit system also includes a water storage device 4;

[0066] The purified water outlet of the water purification device 2 is connected to the purified water port via a second pipeline, and a second solenoid valve 14 is provided on the second pipeline;

[0067] The wastewater solenoid valve 11 is also connected to the water inlet of the water storage device 4 through the third pipeline, the first water outlet of the water storage device 4 is connected to the second water inlet of the salt making device 3 through the fourth pipeline, and the second water outlet of the water storage device 4 is connected to the flushing water outlet through the fifth pipeline; the third solenoid valve 15 is provided on the third pipeline, and the ejector 16 is provided on the fifth pipeline;

[0068] The controller is also used to drive the water purification device 2 to purify the raw water in the water production mode, and drive the second solenoid valve 14, the wastewater solenoid valve 11, and the third solenoid valve 15 to open, so that the treated clean water flows out from the water purification port through the second pipeline, and the treated wastewater flows into the water storage device 4 through the third pipeline;

[0069] The controller is also used to drive the ejector 16 to make the waste water in the water storage device 4 flow out from the flushing water outlet through the fifth pipeline in the flushing water mode;

[0070] In which, when the second liquid level of the wastewater in the water storage device 4 meets the preset liquid level value, the wastewater in the water storage device 4 flows into the salt making device 3 via the fourth pipeline.

[0071] Specifically, in order to further improve the utilization rate of wastewater, a water storage device 4 is provided between the wastewater outlet of the water purification device 2 and the salt box, and the wastewater solenoid valve 11 and the third solenoid valve 15 are connected in series, so that when the water purification device 2 is performing purification treatment, the wastewater solenoid valve 11 and the third solenoid valve 15 are opened to allow wastewater to flow into the water storage device 4 for storage. A first outlet is provided at a preset height position of the water storage device 4 (for example, the top of the water storage device 4) to be connected to the second water inlet of the salt making device 3 through a pipeline, and a second water outlet is provided at the bottom of the water storage device 4 to be connected to the flushing water outlet through an ejector 16, wherein the flushing water outlet can be connected to a toilet or other flushing interface in the user's home.

[0072] When the waste water generated by the water purification device 2 exceeds the preset height of the water storage device 4, the waste water flows into the salt making device 3 through the first outlet; when the flushing water outlet is used with water, the waste water in the water storage device 4 is ejected by driving the ejector 16 for flushing by the user, thereby avoiding direct discharge of waste water and saving water.

[0073] Among them, an overflow port is also provided at a preset position on the top of the salt making device 3, which is used to discharge the salt solution from the salt making device 3 when the first liquid level of the salt solution in the salt making device 3 is higher than the preset position. By setting the overflow port, water can be discharged from the overflow port when the water storage tank and the salt tank are full.

[0074] In a specific embodiment, Figure 3 As shown, the water purification device 2 includes a first filter element 21, a pump 22 and a second filter element 23;

[0075] The controller is also used to drive the first filter element 21 to filter the raw water in the water production mode, and the raw water flows into the second filter element 23 through the pump 22 for further filtering to obtain clean water and waste water;

[0076] The clean water outlet includes a normal temperature clean water outlet and a hot clean water outlet;

[0077] The purified water outlet of the water purifier 2 is connected to the normal temperature purified water outlet via the first sub-pipeline, and is connected to the hot purified water outlet via the second sub-pipeline. The first sub-pipeline is provided with a first sub-solenoid valve 141, and the second sub-pipeline is provided with a heating device 142 and a second sub-solenoid valve 143;

[0078] The controller is also used to drive the water purification device 2 to purify the raw water in the water production mode, and drive the first sub-solenoid valve 141 to open so that the treated clean water flows out from the normal temperature clean water outlet through the first sub-pipeline, or drive the second sub-solenoid valve 143 to open so that the treated clean water flows out from the hot clean water outlet after being heated by the heating device 142 on the second sub-pipeline.

[0079] Specifically, the first filter element 21 can be a front folded PP (polypropylene) rear composite filter element, and the second filter element 23 can be a nanochromatographic filter element. The wastewater outlet of the nanochromatographic filter element is connected to the wastewater solenoid valve 11 to discharge wastewater, and the outlet of the front folded PP rear composite filter element is connected to the water inlet and the normal temperature clean water outlet of the heating device 142 respectively. When the user wants to take normal temperature clean water, the controller drives the front folded PP (polypropylene) rear composite filter element, the pump 22, and the nanochromatographic filter element to filter the raw water, and the generated clean water flows out from the normal temperature clean water outlet through the first sub-pipeline for the user to take; when the user wants to take hot clean water, the controller drives the front folded PP (polypropylene) rear composite filter element, the pump 22, and the nanochromatographic filter element to filter the raw water, and the generated clean water is heated by the heating device 142 according to the preset temperature to adjust the power to achieve instant hot water output, and flows out from the hot clean water outlet for the user to take.

[0080] Among them, the wastewater outlet of the nanochromatographic filter element is also connected to the sewage outlet 2 through a pipeline, and a fifth solenoid valve 17 is provided on the pipeline. The controller controls the wastewater outlet and the fifth solenoid valve 17 to open so that the sewage generated by the nanochromatographic filter element is discharged from the sewage outlet 2.

[0081] In a specific embodiment, Figure 4 As shown, the clean and soft water system also includes a pre-filter device 5;

[0082] The water inlet of the pre-filter device 5 is used to receive raw water, the water outlet of the pre-filter device 5 is connected to the water inlet of the water softener 1 through the sixth pipeline, and the water outlet of the pre-filter device 5 is also connected to the water inlet of the water purifier 2 through the seventh pipeline, and the fourth solenoid valve 18 is provided on the seventh pipeline;

[0083] The controller is also used to drive the pre-filter device 5 to filter the raw water to form filtered water in the soft water regeneration mode, so that the filtered water flows into the softening device 1 through the sixth pipeline for softening treatment;

[0084] The controller is also used to drive the pre-filter device 5 to filter the raw water to form filtered water in the water production mode, and drive the fourth solenoid valve 18 to open so that the filtered water flows into the water purification device 2 through the seventh pipeline for purification.

[0085] Specifically, in order to improve the service life of the water softening device 1 and the water purifying device 2, a pre-filter device 5, for example, a laminated pre-filter, can be set before the water inlet of the water softening device 1 and the water purifying device 2. The laminated pre-filter can simply filter out impurities such as mud, large particles of meat, and visible objects in the raw water, and then send the filtered water to the water softening device 1 or the water purifying device 2 for treatment.

[0086] Among them, since the laminated pre-filter needs to be flushed after a period of use to reduce the risk of contamination of the laminated pre-filter, the laminated pre-filter can be connected to the sewage outlet 3 through a pipeline, and an electric valve 19, such as a ball valve, is arranged on the pipeline. When the laminated pre-filter is flushed, the controller controls the electric valve 19 to open to discharge the flushed sewage from the sewage outlet 3.

[0087] In a specific embodiment, Figure 4 As shown, the water outlet of the pre-filter device 5 is also connected to the flushing water outlet through the eighth pipeline;

[0088] The eighth pipeline is provided with a first one-way valve 61, and the fifth pipeline is provided with a second one-way valve 62;

[0089] The first one-way valve 61 is used to control the outflow of filtered water from the flushing water outlet, and the second one-way valve 62 is used to control the outflow of waste water from the flushing water outlet;

[0090] The water storage device 4 is provided with a second liquid level detection element (not shown in the figure) for detecting a second liquid level signal corresponding to a second liquid level of waste water in the water storage device 4;

[0091] The controller is also used to drive the pre-filter device 5 to filter the raw water to form filtered water in response to not receiving the second liquid level signal in the flushing water mode, and the filtered water flows out from the flushing water outlet through the eighth pipeline.

[0092] Specifically, the water outlet of the ejector 16 is connected to the water outlet of the pre-filter device 5 and the water inlet of the flushing water outlet, so that when there is no waste water in the water storage device 4, the filtered water filtered by the pre-filter device 5 flows directly to the flushing water outlet to meet the user's use needs. At the same time, a first one-way valve 61 is provided at the water outlet of the pre-filter device 5 and a second one-way valve 62 is provided at the water outlet of the ejector 16 to ensure that the filtered water or waste water flows out of the flushing water outlet.

[0093] In a specific embodiment, the water outlet of the pre-filter device 5 is also connected to the cleaning water outlet through a ninth pipeline;

[0094] The controller is also used to drive the pre-filter device 5 to filter the raw water to form filtered water in the cleaning water mode, and the filtered water flows out from the cleaning water outlet through the ninth pipeline.

[0095] Specifically, the water outlet of the laminated pre-filter is divided into four routes, wherein the first route of water supplies the softening device 1, the second route of water supplies the water purification device 2, the third route of water supplies the flushing water outlet for flushing toilets in the user's home, and the fourth route of water supplies the cleaning water outlet for cleaning by the user.

[0096] In a specific embodiment, the controller is further configured to enter an unlock mode in response to the system being powered on;

[0097] The controller is also used to enter the whole machine flushing mode in response to successful unlocking, and the whole machine flushing mode is used for flushing the water purification device 2;

[0098] The controller is also used to respond to the end of flushing of the whole machine, determine the target mode according to the user's instruction, and drive the clean and soft water system to enter the target mode;

[0099] The target mode includes one of a soft water regeneration mode, a water production mode, a flushing water mode, and a cleaning water mode.

[0100] In a specific example, if Figure 4-5 As shown, the controller controls the operation process of the clean and soft water system in different modes as follows:

[0101] 1. Start power-on unlocking: When the clean and soft water system is powered on for the first time, the whole machine needs to enter the unlocking mode, that is, the controller needs to be decoded first and then the clean and soft water system can enter the next mode.

[0102] 2. Whole machine flushing mode: Before entering this mode, you need to confirm whether it has been successfully unlocked. When the system is successfully unlocked, the system enters the whole machine flushing mode. By controlling the fourth solenoid valve 18, pump 22, waste water solenoid valve 11, and fifth solenoid valve 17 to open for 30 minutes; after 30 minutes, the fourth solenoid valve 18, pump 22, and first sub-solenoid valve 141 are controlled to open for 35 minutes; after 35 minutes, the fourth solenoid valve 18, pump 22, and second sub-solenoid valve 143 are controlled to open for 35 minutes; after completing the above actions, the whole machine flushing mode is completed.

[0103] 3. Water production mode: When the user wants to take normal temperature purified water, the controller controls the fourth solenoid valve 18, the pump 22, the waste water solenoid valve 11, the third solenoid valve 15, and the first sub-solenoid valve 141 to open. At this time, the normal temperature purified water flows out of the normal temperature purified water outlet after being purified by the water purification device 2. When the user wants to take hot purified water, the fourth solenoid valve 18, the pump 22, the waste water solenoid valve 11, the third solenoid valve 15, and the second sub-solenoid valve 143 are opened. At this time, after being purified by the water purification device 2, the heating device 142 adjusts the power output according to the preset temperature of the system to heat the purified purified water, so as to achieve instant hot water output. Through the above water production mode, all the waste water generated by the water purification device 2 is collected in the water storage device 4. The first water outlet of the water storage device 4 is connected to the second water inlet of the salt making device 3. The waste water will continue to be discharged into the salt making device 3. If the salt making device 3 is also full, then the water will flow out from the overflow port of the salt making device 3.

[0104] 4. Flushing water mode: The flushing water outlet is connected to the toilet in the user's home. Whether it is a smart toilet or an ordinary toilet, as long as there is water use, the controller will first control the ejector 16 to suck out the waste water in the water storage device 4 and flow out through the flushing water outlet for flushing. If there is no waste water in the water storage device 4, the controller will control the laminated pre-filter to filter the raw water and then flow out directly through the flushing water outlet to meet the user's needs. In this way, as long as the amount of flushing water used can reach the total amount preset by the system, no wastewater discharge can be achieved.

[0105] 5. Cleaning water mode: The cleaning water outlet can be connected to the user's kitchen water. As long as the user turns on the kitchen faucet, the controller will control the laminated pre-filter to filter the raw water and then flow out directly through the cleaning water outlet to meet the user's needs.

[0106] 6. Soft water regeneration mode: The system does not need to be regenerated when using soft water for the first time. It will enter the soft water regeneration mode only when the water usage reaches the water production volume, that is, when the user's water consumption reaches the soft water regeneration water consumption, the system enters the soft water regeneration mode. During soft water regeneration, the liquid level float in the salt making device 3 will first detect whether the salt solution level can be detected. If the liquid level is detected at this time, the soft water device 1 is controlled to enter the soft water regeneration mode, that is, the soft water device 1 starts to absorb salt through the salt absorption pipe, and at the same time discharges sewage through the sewage outlet 1 of the soft water device 1. This process will last for 70 minutes, mainly to allow the sodium chloride in the salt solution to fully replace the calcium and magnesium ions in the resin, and then discharge the replaced calcium and magnesium ions through the sewage outlet 1; if the liquid level float in the salt making device 3 does not detect the salt level, the fourth solenoid valve 18, the pump 22, the wastewater solenoid valve 11, and the first solenoid valve 12 are controlled to open, and the above components are closed when the liquid level float detects the level of the salt solution. After 25 minutes, the soft water device 1 is controlled to enter the soft water regeneration mode.

[0107] This embodiment integrates the water purification device and the water softening device into the clean and soft water system for centralized control and operation, generates salt from the wastewater generated by the water purification device for use by the water softening device, and discharges the wastewater through the flushing water outlet for daily toilet flushing by the user, thereby realizing wastewater reuse, and when the amount of water used in the flushing water outlet reaches the total amount preset by the system, no wastewater is discharged, thus saving water resources.
