[0057] Embodiment 2

[0058] The embodiment provides a water purification integrated device, which is a further improvement of the embodiment 1.

[0059] In an implementable scheme, the first water purification module 1 includes a polypropylene melt-blown filter core.

[0060] Specifically, the polypropylene melt-blown filter core part of the front filter core of the terminal water purifier is removed from the front position, and the activated carbon and quartz stone of the central water purifier are replaced, that is, the polypropylene melt-blown filter core is arranged in the central water purifier. The volume of the polypropylene melt-blown filter core is increased, so that it can match the pollution capacity of whole-house water supply, and the problems of the whole-house water supply system or the water purification integrated device such as various types, inconvenient installation and large size are solved. The polypropylene melt-blown filter core replaces the activated carbon and quartz sand, which can not only play a role in rough filtration, but also retain the residual chlorine in the tap water. The residual chlorine can appropriately improve the growth of bacteria in the rear-end soft water, and delay the problem of odor of dead water.

[0061] In the scheme, the polypropylene melt-blown filter core is arranged in the first water purification module, the convenience of installation of the water purification integrated device is ensured, and the safety of water use of the user is improved.

[0068] The control unit 31 is configured to drive the heating unit 32 to heat the second purified water in the water inlet pipeline 4 to output hot water.

[0069] The hot water is used to melt the salt in the salt storage unit 33 to obtain salt water, and the salt water is used to restore the failed resin in the resin storage unit 34 to usable resin, and the usable resin is used to soften the first purified water to obtain soft water. Figure 2 The arrow in the water inlet pipeline 4 indicates the water flow direction.

[0070] Specifically, the heating unit can be a heating body, the salt storage unit can be a salt tank, and the resin storage unit can be a resin tank. The control unit is configured to drive the heating unit to heat the second purified water in the water inlet pipeline. The power of the heating unit can be maintained to heat the second purified water to a range of 40-70 degrees Celsius until the salt tank is full of water. By adding hot water to the salt tank, the 40-70℃ intermediate temperature accelerates the salt melting speed, the purified water increases the salt melting saturation concentration, and the resin regeneration time is accelerated, which to some extent alleviates the problem of long resin regeneration cycle in a low water temperature environment. 40-70 is only an example, which can be set or adjusted according to actual conditions.

[0071] In this scheme, the heating unit is arranged in the water inlet pipeline to obtain hot water, which is used to melt the salt in the salt storage unit to obtain salt water. The obtained salt water is used to restore the failed resin in the resin storage unit, that is, the hot salt water is used to restore the failed resin, which reduces the restoration period, improves the restoration effect, guarantees the soft water treatment effect, improves the user experience, and improves the product performance of the purified water integrated device.

[0072] In an implementable scheme, the soft water module 3 further comprises a softening duration acquisition unit;

[0073] The softening duration acquisition unit is electrically connected with the control unit 31;

[0074] The softening duration acquisition unit is configured to acquire the working duration of the soft water module 3 for softening treatment and output to the control unit 31;

[0075] The control unit 31 is further configured to drive the heating unit 32 to heat the second purified water in the water inlet pipeline 4 according to the working duration.

[0076] Specifically, when the control unit detects that the cumulative softening treatment working duration of the purified water integrated device reaches the first preset duration, the heating unit is driven to heat the second purified water in the water inlet pipeline.

[0077] In the scheme, according to the softening treatment time of the water purification integrated device, the heating unit is driven to heat the second purified water in the water inlet pipeline to output hot water, the hot water is used to melt the salt stored in the salt storage unit to obtain brine, the brine is used to restore the invalid resin in the resin storage unit to available resin, the hot water is dynamically and flexibly controlled to add to the salt storage unit, and the invalid resin is restored by using the hot brine, the restoration period is reduced, the restoration effect is improved, the subsequent soft water treatment effect is guaranteed, and the user experience is improved.

[0078] In an implementable scheme, the soft water module 3 further comprises a softened water amount acquisition unit;

[0079] The softened water amount acquisition unit is electrically connected with the control unit 31;

[0080] The softened water amount acquisition unit is used to acquire the softened water amount of the soft water module 3 for softening treatment and output to the control unit 31;

[0081] The control unit 31 is further used to drive the heating unit 32 to heat the second purified water in the water inlet pipeline 4 according to the softened water amount.

[0082] Specifically, when the control unit detects that the softened water amount of the water purification integrated device reaches a first preset water amount, the heating unit is driven to heat the second purified water in the water inlet pipeline.

[0083] In the scheme, according to the softened water amount of the water purification integrated device for softening treatment, the heating unit is driven to heat the second purified water in the water inlet pipeline to output hot water, the hot water is used to melt the salt stored in the salt storage unit to obtain brine, the brine is used to restore the invalid resin in the resin storage unit to available resin, the hot water is dynamically and flexibly controlled to add to the salt storage unit, and the invalid resin is restored by using the hot brine, the restoration period is reduced, the restoration effect is improved, the subsequent soft water treatment effect is guaranteed, and the user experience is improved.

[0084] In an implementable scheme, the soft water module 3 further comprises a first temperature acquisition unit 35;

[0085] The first temperature acquisition unit 35 is arranged at the water inlet of the salt storage unit 33, and the first temperature acquisition unit 35 is electrically connected with the control unit 31;

[0086] The first temperature acquisition unit 35 is used to acquire a first hot water temperature of the hot water at the water inlet of the salt storage unit 33 and output to the control unit 31;

[0087] The control unit 31 is further used to drive the heating unit 32 to heat the second purified water in the water inlet pipeline 4 according to the first hot water temperature.

[0088] Specifically, the first temperature acquisition unit is arranged at the water inlet of the salt storage unit to acquire the first hot water temperature of the hot water flowing out of the water inlet after being heated by the heating unit, and the control unit drives the heating unit according to the first hot water temperature to maintain the water temperature of the water flowing into the water inlet of the salt storage unit and accelerate the melting of the salt stored in the salt storage unit to obtain brine.

[0089] In the scheme, the first temperature acquisition unit is arranged to acquire the first hot water temperature of the water inlet of the salt storage unit, and the control unit drives the heating unit according to the first hot water temperature to ensure the stability of the water temperature of the water inlet of the salt storage unit, shorten the salt melting time, and improve the salt melting efficiency.

[0090] In an implementable scheme, the soft water module 3 further comprises a second temperature acquisition unit 36.

[0091] The second temperature acquisition unit 36 is arranged at the water outlet of the salt storage unit 33, and the second temperature acquisition unit 36 is electrically connected with the control unit 31.

[0092] The second temperature acquisition unit 36 is arranged at the water outlet of the salt storage unit 33, and the second temperature acquisition unit 36 is electrically connected with the control unit 31.

[0093] The second temperature acquisition unit 36 is arranged at the water outlet of the salt storage unit 33, and the second temperature acquisition unit 36 is electrically connected with the control unit 31.

[0094] Specifically, after the hot water flows into the salt storage unit, although the salt melting speed is accelerated, there is still a certain salt melting time, and the water temperature will decrease to a certain extent according to the ambient temperature. Therefore, before the resin reduction absorbs the salt, hot water is added to the salt storage unit to warm it up, and the second temperature acquisition unit is arranged at the water outlet of the salt storage unit to ensure the stability of the water temperature of the water outlet of the salt storage unit.

[0095] In the scheme, the second temperature acquisition unit is arranged to acquire the second hot water temperature of the water outlet of the salt storage unit, and the control unit drives the heating unit according to the second hot water temperature to ensure the stability of the water temperature of the water outlet of the salt storage unit, overcome the problem of salt particles precipitating due to temperature reduction, prevent the problem of too many precipitated salt particles blocking the pore channel, and improve the safety and reliability of the integrated soft water device.

[0096] In an implementable scheme, the shell material of the second temperature acquisition unit 36 is plastic.

[0097] Specifically, considering that the second temperature acquisition unit is in the brine output by the salt storage unit, a temperature sensor with a plastic shell hardware is adopted.

[0098] In the scheme, the second temperature acquisition unit improves the service life of the second temperature acquisition unit by adopting a plastic shell, thereby saving costs.

[0099] In an implementable scheme, the soft water module 3 further comprises a booster pump 37.

[0100] The booster pump 37 is arranged in the water inlet pipeline 4, and the booster pump 37 is electrically connected with the control unit 31.

[0101] The control unit 31 is further configured to adjust the control voltage of the booster pump 37 according to the first hot water temperature or the second hot water temperature, so as to drive the heating unit 32 to heat the second purified water in the water inlet pipeline 4.

[0102] Specifically, since the control voltage of the booster pump has a certain deviation, the power of the heating unit remains unchanged, and therefore the first outlet water temperature NTC1 of the first temperature acquisition unit and the control voltage V of the booster pump form a closed-loop control, and a PID (proportion, integration and differentiation) control algorithm is adopted to keep the outlet water temperature constant, and the corresponding calculation formula is as follows:

[0103] V = Kp2 * e(t) + Ki2 * Σe(t) + Kd2 * (e(t) - e(t-1));

[0104] e(t) = Tob - NTC1;

[0105] Wherein, V represents the control voltage of the booster pump, Tob represents the preset target temperature, NTC1 represents the first outlet water temperature, e(t) represents the current temperature error, e(t-1) represents the previous temperature error; Kp2, Ki2, Kd2 represent the system parameters of the PID, which can be set according to experience.

[0106] The second outlet water temperature NTC2 of the second temperature acquisition unit is similar to the first outlet water temperature NTC1 of the first temperature acquisition unit, and forms a closed-loop control with the control voltage V of the booster pump, adopts a PID control algorithm to ensure the stability of the outlet water temperature, which will not be described here.

[0107] In addition, a purified water module water inlet valve, a motor pump, a salt storage unit water supplement valve can also be arranged in the water inlet pipeline, and the purified water module water inlet valve, the booster pump, the motor pump, the heating unit and the salt storage unit water supplement valve are arranged in sequence, the purified water module water inlet valve is connected with the outlet pipeline of tap water or the outlet of the first purified water module, and the salt storage unit water supplement valve is connected with the water inlet of the salt storage unit.

[0108] When the control unit detects that the cumulative softening treatment working time of the water purification integrated device reaches the first preset time length and / or the softening water amount reaches the first preset water amount, the water inlet valve, the booster pump, the motor pump, the heating unit, and the salt storage unit water supplement valve of the water purification module are powered on to heat the water in the water inlet pipeline until the salt tank is full of water.

[0109] In this scheme, the booster pump is arranged in the water inlet pipeline, and the control unit adjusts the control voltage of the booster pump according to the first hot water temperature to drive the heating unit to heat the water in the water inlet pipeline, thereby stabilizing the water temperature at the water inlet of the salt storage unit and improving the stability and reliability of the water purification integrated device. The booster pump is arranged in the water inlet pipeline, and the control unit adjusts the control voltage of the booster pump according to the second hot water temperature to drive the heating unit to heat the water in the water inlet pipeline, thereby stabilizing the water temperature at the water outlet of the salt storage unit and improving the stability and reliability of the water purification integrated device.

[0110] In an implementable scheme, the soft water module 3 further comprises a water path control switch 38 and a hot water pipeline 39;

[0111] The water path control switch 38 is electrically connected with the control unit 31, and the hot water pipeline 39 communicates with the water inlet pipeline 4;

[0112] The control unit 31 is further configured to drive the water path control switch 38 to open, so as to communicate the hot water pipeline 39 and the resin storage unit 34, and to make the hot water output to the resin storage unit 34 through the hot water pipeline 39.

[0113] Specifically, a branch is newly added to the water path control switch at the rear end of the heating unit of the water inlet pipeline, and the newly added branch is the hot water pipeline. The water path control switch can be a multi-water path control valve. The multi-water path control valve communicates the tap water outlet pipeline, the resin storage unit, the hot water pipeline, the water outlet of the salt storage unit, the waste water outlet, and the soft water outlet. The control unit can control the opening state of the valve of the multi-water path control valve, so as to communicate different pipelines, units, and water outlets. During the resin reduction (or regeneration), the internal switch of the multi-water path control valve is switched to communicate the hot water pipeline and the resin storage unit, and the water in the water inlet pipeline is heated to a suitable water temperature for the resin regeneration reaction by the heating unit. The suitable water temperature is a preset value, which can be obtained by test experiments. The hot salt water output from the water outlet of the salt storage unit is saturated concentrated salt hot water. After mixing with the normal temperature tap water output from the tap water outlet pipeline, the mixed salt water has a reduced temperature. After the hot water pipeline and the resin storage unit are communicated, the problem of salt particle precipitation caused by the temperature reduction of the mixed salt water is overcome.

[0114] In the scheme, the hot water at the rear end of the water inlet pipeline is output to the resin storage unit through the hot water pipeline, which overcomes the problem of salt particle precipitation caused by the temperature drop after mixing saturated concentrated salt hot water with normal temperature tap water, prevents the problem of excessive salt particles precipitated from blocking the pore, improves the safety and reliability of the soft water module, ensures that the water temperature of the resin reduction reaction is optimal, overcomes the problem of long reduction period of the resin in a low temperature environment, reduces the reduction period, improves the reduction effect, ensures the subsequent soft water treatment effect, improves the user experience, and improves the product performance of the water purification integrated device.

[0115] The working principle of the water purification integrated device of the present embodiment will be described below in conjunction with specific examples.

[0116] As shown in Figure 3 , the water purification integrated device integrates a first water purification module 1, a second water purification module 2, and a soft water module 3, and further includes a water inlet pipeline 4. The soft water module 3 includes a control unit 31, a heating unit 32, a salt storage unit 33, a resin storage unit 34, a first temperature acquisition unit 35, a second temperature acquisition unit 36, a booster pump 37, a water path control switch 38, a hot water pipeline 39, a water purification module water inlet valve 40, a motor pump 41, a salt storage unit water replenishment valve 42. The first water purification module 1 includes a polypropylene melt-blown filter core 11, the second water purification module 2 includes a pre-composite unit 22, an RO / NF (reverse osmosis / nanofiltration) filter core 23, a post-composite unit 24, and an ultraviolet sterilization unit 25. The water purification integrated device further includes a water valve assembly 51, a flow meter 53, a first one-way valve 53, a second one-way valve 54, a third one-way valve 55, a concentrated water valve 56, a normal temperature water discharge valve 57, and a hot water discharge valve 58.

[0117] The control unit can be a controller integrated in the water purification integrated device or the soft water module. The control unit is electrically connected with the heating unit, the water path control switch, the booster pump, the water purification module water inlet valve, the motor pump, the first temperature acquisition unit, and the second temperature acquisition unit.

[0118] The first purified water is obtained by filtering the municipal tap water through the polypropylene melt-blown filter element 11, and flows into the water path control switch 38 and the purified water module water inlet valve 40, respectively. After the control unit 31 drives the purified water module water inlet valve 40 to be powered on, the first purified water flows into the pre-combined unit 22, the booster pump 37, and the RO / NF filter element 23 in sequence. The purified water obtained by filtering through the RO / NF filter element 23 flows through the post-combined unit 24, the third one-way valve 55, and the ultraviolet sterilization unit 54 in sequence. The wastewater obtained by filtering through the RO / NF filter element 23 flows through the concentrated water valve 56 and the second one-way valve 54 in sequence and then flows out. The purified water obtained by the ultraviolet sterilization unit 25 can be discharged as normal-temperature purified water through the normal-temperature water outlet valve 57 for use by the user. In addition, the purified water can flow through the water valve assembly 51, the flow meter 52, the motor pump 41, the heating unit 32, and the first temperature acquisition unit 35 in sequence. The purified water passing through the first temperature acquisition unit 35 can be discharged as purified hot water through the hot water outlet valve 58 for use by the user. The purified water can flow into the water path control switch 38 through the hot water pipeline 39, and can flow into the water path control switch 38 through the salt storage unit water supplement valve 42, the salt storage unit 33, and the second temperature acquisition unit 36 in sequence. The resin storage unit 34 is in communication with the water path control switch 38. Soft water and wastewater can be obtained after passing through the resin storage unit 34. The wastewater flows out through the first one-way valve 53 in communication with the water path control switch 38.

[0119] During the resin reduction process, the control unit detects the cumulative softening treatment working time and / or the softening water volume of the purified water integrated device, and determines whether the softening treatment working time reaches a first preset time and / or the softening water volume reaches a first preset water volume. If not, the control unit continues to detect the cumulative softening treatment working time and / or the softening water volume of the purified water integrated device. If so, the control unit drives the purified water module water inlet valve, the booster pump, the motor pump, the heating unit, and the salt storage unit water supplement valve to be powered on.

[0120] The first temperature acquisition unit acquires the first hot water temperature NTC1 of the water inlet of the salt storage unit, and the control unit drives the booster pump to adjust the control voltage by using the PID algorithm to heat the water in the water inlet pipeline. The control unit detects whether the salt storage unit is full of water. If not, the first temperature acquisition unit continues to acquire the first hot water temperature NTC1 of the water inlet of the salt storage unit. If so, the control unit drives the purified water module water inlet valve, the booster pump, the motor pump, the heating unit, and the salt storage unit water supplement valve to be powered off.

[0121] After the salt particles are dissolved in the hot water in the salt storage unit for a period of time, the control unit determines whether the softening treatment working time reaches a second preset time and / or the softening water volume reaches a second preset water volume. If so, the control unit drives the purified water module water inlet valve, the booster pump, the motor pump, the heating unit, and the salt storage unit water supplement valve to be powered on. The second temperature acquisition unit acquires the second hot water temperature NTC2 of the water outlet of the salt storage unit, and the control unit drives the booster pump to adjust the control voltage by using the PID algorithm to heat the water in the water inlet pipeline.

[0122] The control unit determines whether the second hot water temperature NTC2 reaches a preset temperature. If not, the second temperature acquisition unit continues to acquire the second hot water temperature NTC2 of the outlet of the salt storage unit. If yes, the control unit drives the salt storage unit water replenishment valve to be powered off, and the waterway control switch is powered on until the resin storage unit is connected to regenerate the resin. The resin starts slow absorption regeneration. The control unit determines whether the slow absorption time length reaches a third preset time length. If the slow absorption time length does not reach the third preset time length, the resin continues slow absorption regeneration. If the slow absorption time length reaches the third preset time length, the control unit drives the water purification module water inlet valve, booster pump, motor pump, heating unit, and salt storage unit water replenishment valve to be powered off, and the waterway control switch is powered on until the municipal tap water is connected to perform softening work.
