[0050] The present disclosure is further illustrated below by way of embodiments, but the present disclosure is not limited to the scope of the embodiments described herein.

[0051] The prefixes such as "first" and "second" used in this disclosure are merely for distinguishing different descriptive objects and do not limit the position, order, priority, quantity, or content of the described objects. The use of ordinal numbers and other prefixes used to distinguish descriptive objects in this disclosure does not constitute a limitation on the described objects.

[0052] Example 1

[0053] In one specific embodiment of this disclosure, a water purification and softening system is provided, such as... Figure 1 As shown, the water purification and softening system includes a controller (not shown in the figure), a water 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 inlet of the salt making device 3 through the first pipeline;

[0055] The brine inlet of the water softener 1 is connected to the salt production device 3 via a brine suction pipe;

[0056] Both the inlet of the water softener 1 and the inlet of the water purifier 2 are used to connect to raw water;

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

[0058] The controller is used to drive the water softening device 1 to draw salt solution from the salt making device 3 through the brine suction pipe in the water softening regeneration mode, so as to soften the raw water to generate soft water, which then flows out through the soft water outlet.

[0059] Specifically, after purifying the raw water, the water purification device 2 generates wastewater along with purified water. The water softening device 1 (e.g., a water softener) needs to periodically add salt (sodium chloride) to combine with calcium and magnesium ions in the water to reduce water hardness and achieve water softening. Therefore, the wastewater generated by the water purification device 2 during the purification process is stored in the salt-making device 3 (e.g., a salt tank) to dissolve the salt in the salt-making device 3 and form a salt solution. When the water softening usage reaches the production capacity, the water softening regeneration mode is triggered. The controller drives the water softening device 1 to draw salt solution from the salt-making device 3 through the salt suction pipe of the salt suction port, so that the sodium chloride in the salt solution can fully replace the calcium and magnesium ions in the resin to generate soft water, which flows out through the soft water outlet for user use. The replaced calcium and magnesium ions can be discharged through the drain outlet 1.

[0060] This specific embodiment centrally controls the water purification device 2 and the water softening device 1, and stores the wastewater generated by the water purification device 2 during the purification process 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 wastewater.

[0061] In one specific implementation, such as Figure 1 As shown, a wastewater solenoid valve 11 and a first solenoid valve 12 are sequentially installed on the first pipeline along the wastewater flow direction;

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

[0063] The controller is also used in soft water regeneration mode to drive the water purification device 2 to purify the raw water in response to the absence of the first liquid level signal, and to 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 to drive the soft water device 1 to draw salt solution from the salt making device 3 through the salt suction pipe in response to the receipt of the first liquid level signal, so as to soften the raw water to generate soft water, and to flow out through the soft water outlet.

[0064] Specifically, a first liquid level detection element 13, such as a liquid level float, can be installed 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 soft water device 1 can directly draw salt from the salt-making device 3 through the salt suction pipe to soften the raw water and form soft water; 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 wastewater solenoid valve 11 and the first solenoid valve 12 are driven to open so that the wastewater 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 wastewater solenoid valve 11 and the first solenoid valve 12 are driven to close, and then the soft water device 1 is driven to draw salt to generate soft water.

[0065] In one specific implementation, such as Figure 2 As shown, the water purification and softening 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 outlet via a second pipeline, and a second solenoid valve 14 is installed on the second pipeline;

[0067] Wastewater solenoid valve 11 is also connected to the inlet of water storage device 4 through a third pipeline. The first outlet of water storage device 4 is connected to the second inlet of salt making device 3 through a fourth pipeline. The second outlet of water storage device 4 is connected to the flushing water outlet through a fifth pipeline. A third solenoid valve 15 is provided on the third pipeline, and an 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 to drive the second solenoid valve 14, the wastewater solenoid valve 11 and the third solenoid valve 15 to open so that the treated purified water flows out from the water outlet 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 jet injector 16 to discharge wastewater from the water storage device 4 through the fifth pipeline from the flushing water outlet in the flushing water mode.

[0070] 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 through the fourth pipeline.

[0071] Specifically, to further improve the utilization rate of wastewater, a water storage device 4 is installed between the wastewater outlet of the water purification device 2 and the salt tank. A wastewater solenoid valve 11 and a third solenoid valve 15 are connected in series. When the water purification device 2 is performing purification treatment, the wastewater solenoid valve 11 and the third solenoid valve 15 are opened, allowing wastewater to flow into the water storage device 4 for storage. A first outlet is installed at a preset height position of the water storage device 4 (e.g., the top of the water storage device 4) and connected to the second inlet of the salt making device 3 via a pipe. A second outlet is installed at the bottom of the water storage device 4 and connected to a flushing outlet via an ejector 16. The flushing outlet can be connected to a toilet or other flushing interface in the user's home.

[0072] When the wastewater generated by the water purification device 2 exceeds the preset height of the water storage device 4, the wastewater flows into the salt making device 3 through the first outlet; when there is a water usage action at the flushing water outlet, the wastewater in the water storage device 4 is ejected by the driven jet ejector 16 for the user to flush, thus avoiding the direct discharge of wastewater and saving water.

[0073] The salt-making device 3 is equipped with an overflow port at a preset position on its top. This overflow port 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 both the water tank and the salt tank are full.

[0074] In one specific implementation, such as 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 water production mode, and then flow into the second filter element 23 via the pump 22 for further filtration to obtain purified water and wastewater.

[0076] Water purification outlets include ambient temperature water purification outlets and hot water purification outlets;

[0077] The purified water outlet of the water purification device 2 is connected to the ambient temperature purified water outlet via the first sub-pipeline and to the hot purified water outlet via the second sub-pipeline. The first sub-pipeline is equipped with a first sub-solenoid valve 141, and the second sub-pipeline is equipped 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 purified water flows out from the normal temperature purified water port through the first sub-pipeline, or drive the second sub-solenoid valve 143 to open so that the treated purified water flows out from the hot purified water port after being heated by the heating device 142 on the second sub-pipeline.

[0079] Specifically, the first filter element 21 can be a pre-folded PP (polypropylene) post-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. The outlet of the pre-folded PP post-composite filter element is connected to the inlet of the heating device 142 and the ambient temperature purified water outlet, respectively. When the user wants ambient temperature purified water, the controller drives the pre-folded PP (polypropylene) post-composite filter element, pump 22, and nanochromatographic filter element to filter the raw water, generating purified water that flows out from the ambient temperature purified water outlet through the first sub-pipeline for the user to use. When the user wants hot purified water, the controller drives the pre-folded PP (polypropylene) post-composite filter element, pump 22, and nanochromatographic filter element to filter the raw water, generating purified water that is heated by the heating device 142 according to the preset temperature adjustment power to achieve instant hot water output, which flows out from the hot purified water outlet for the user to use.

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

[0081] In one specific implementation, such as Figure 4 As shown, the water purification and softening system also includes a pre-filter 5;

[0082] The inlet of the pre-filter 5 is used to connect to the raw water. The outlet of the pre-filter 5 is connected to the inlet of the soft water device 1 through the sixth pipe. The outlet of the pre-filter 5 is also connected to the inlet of the water purification device 2 through the seventh pipe. A fourth solenoid valve 18 is provided on the seventh pipe.

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

[0084] The controller is also used in water production mode to drive the pre-filter device 5 to filter the raw water to form filtered water, and to 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 softener 1 and the water purifier 2, a pre-filter 5 can be installed before the inlet of the water softener 1 and the water purifier 2. For example, a disc pre-filter can be installed to simply filter out impurities such as mud, large particles of meat, and visible matter in the raw water. The filtered water is then sent to the water softener 1 or the water purifier 2 for further treatment.

[0086] Since the disc pre-filter needs to be flushed after a period of use to reduce the risk of contamination, the disc pre-filter can be connected to the drain outlet 3 through a pipeline, and an electric valve 19, such as a ball valve, can be installed on the pipeline. When flushing the disc pre-filter, the controller controls the electric valve 19 to open so that the flushing wastewater can be discharged from the drain outlet 3.

[0087] In one specific implementation, such as Figure 4 As shown, the outlet of the pre-filter 5 is also connected to the flushing outlet through the eighth pipe.

[0088] The eighth pipeline is equipped with a first check valve 61, and the fifth pipeline is equipped with a second check valve 62;

[0089] The first check valve 61 is used to control the flow of filtered water from the rinsing water outlet, and the second check valve 62 is used to control the flow of wastewater from the rinsing water outlet.

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

[0091] The controller is also used in flushing water mode to drive the pre-filter 5 to filter the raw water to form filtered water in response to the absence of a second liquid level signal. The filtered water flows out from the flushing water outlet through the eighth pipeline.

[0092] Specifically, by connecting the outlet of the jet injector 16 to the outlet of the pre-filter device 5 and simultaneously to the inlet of the flushing water outlet, the filtered water from the pre-filter device 5 can flow directly to the flushing water outlet when there is no wastewater in the water storage device 4, thus meeting the user's needs. At the same time, by installing a first one-way valve 61 at the outlet of the pre-filter device 5 and a second one-way valve 62 at the outlet of the jet injector 16, it is ensured that filtered water or wastewater flows out from the flushing water outlet.

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

[0094] The controller is also used to drive the pre-filter 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 disc pre-filter is divided into four channels: the first channel supplies water to the water softener 1, the second channel supplies water to the water purifier 2, the third channel supplies water to the flushing outlet for flushing the toilet in the user's home, and the fourth channel supplies water to the cleaning outlet for the user's cleaning use.

[0096] In one specific implementation, the controller is also configured to enter an unlocked mode in response to system power-on;

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

[0098] The controller is also used to respond to the end of the whole machine flushing, determine the target mode according to the user's instructions, and drive the water purification and softening circuit system into the target mode;

[0099] The target modes include one of the following: soft water regeneration mode, water production mode, flushing water mode, and cleaning water mode.

[0100] In a specific example, such as Figure 4-5 As shown, the controller operates the water purification and softening system in different modes as follows:

[0101] 1. Power-on unlocking: When the water purification and softening system is powered on for the first time, the entire unit needs to enter the unlocking mode. That is, the controller needs to be decoded before the water purification and softening system can enter the next mode.

[0102] 2. Whole Machine Flushing Mode: Before entering this mode, it is necessary to confirm that the system has been successfully unlocked. Once the system is successfully unlocked, it enters the whole machine flushing mode. The system controls the opening of the fourth solenoid valve 18, pump 22, wastewater solenoid valve 11, and fifth solenoid valve 17 for 30 minutes. After 30 minutes, the system controls the opening of the fourth solenoid valve 18, pump 22, and first sub-solenoid valve 141 for 35 minutes. After 35 minutes, the system controls the opening of the fourth solenoid valve 18, pump 22, and second sub-solenoid valve 143 for 35 minutes. After completing the above actions, the whole machine flushing mode is finished.

[0103] 3. Water Production Mode: When the user wants room temperature purified water, the controller opens the fourth solenoid valve 18, pump 22, wastewater solenoid valve 11, third solenoid valve 15, and first sub-solenoid valve 141. At this time, the purified water is processed by the water purification device 2 and flows out from the room temperature water outlet. When the user wants hot purified water, the fourth solenoid valve 18, pump 22, wastewater solenoid valve 11, third solenoid valve 15, and second sub-solenoid valve 143 open. After purification by the water purification device 2, the heating device 142 adjusts its power output according to the system's preset temperature to heat the purified water, providing instant hot water. Through the above water production mode, all wastewater generated by the water purification device 2 is collected in the water storage device 4. The first outlet of the water storage device 4 is connected to the second inlet of the salt-making device 3, and the wastewater continues to be discharged into the salt-making device 3. If the salt-making device 3 is also full, the water will flow out from its overflow outlet.

[0104] 4. Flushing Water Mode: The flushing water outlet connects to the user's toilet. Whether it's a smart toilet or a regular toilet, whenever water is used, the controller will first control the jet injector 16 to draw wastewater from the water storage device 4 and allow it to flow out through the flushing water outlet for flushing. If there is no wastewater in the water storage device 4, the controller will control the disc pre-filter to filter the raw water before it flows directly out through the flushing water outlet to meet the user's needs. In this way, as long as the amount of flushing water used reaches the system's preset total amount, no wastewater discharge can be achieved.

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

[0106] 6. Soft Water Regeneration Mode: The system does not require regeneration when using soft water for the first time. It only enters soft water regeneration mode when the water usage reaches the production capacity. During soft water regeneration, the float in the salt-making device 3 will first detect whether the salt solution level is detectable. If the level is detected, the soft water device 1 will enter soft water regeneration mode. The device will begin to draw salt through the suction pipe and simultaneously discharge wastewater through the drain outlet 1. This process will last for 70 minutes, primarily to allow the sodium chloride in the salt solution to fully exchange with the calcium and magnesium ions in the resin. The displaced calcium and magnesium ions will then be discharged through the drain outlet 1. If the float in the salt-making device 3 does not detect the salt level, the fourth solenoid valve 18, pump 22, wastewater solenoid valve 11, and first solenoid valve 12 will be opened. Once the float detects the salt solution level, these components will be closed. After 25 minutes, the soft water device 1 will enter soft water regeneration mode.

[0107] This embodiment integrates a water purification device and a water softening device into a centralized water system for centralized control. Wastewater from the purification device is converted into salt for use in the softening device, while wastewater is discharged through a flushing outlet for daily toilet flushing, achieving wastewater reuse. Furthermore, when the flushing water usage reaches a preset system limit, no wastewater is discharged, conserving water resources. Simultaneously, the water system meets users' daily needs for soft water, purified water, cleaning water, and flushing water, enhancing the user experience.

[0108] While specific embodiments of this disclosure have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this disclosure 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 disclosure, but all such changes and modifications fall within the scope of protection of this disclosure.
