Therefore, the pH change of the electrolyzed ionized water is not large in the ratio of the amount of water, it is possible to obtain stable electrolytic ionized water.

Therefore, the inflow water introduced through the inlet 5 of the primary electrolytic bath 10 is introduced into the primary acidic water generation electrode chamber 12 and the alkaline water generation electrode chamber 13 through the primary intake control membrane 16. The acidic water generated in the primary acidic water generating electrode chamber 12 by being electrolyzed for a sufficient time while being gradually filled up is determined through the primary acidic water outlet 6 formed in the upper portion of the primary acidic water generating electrode chamber 12. Alkaline water is discharged to the outside, and the alkaline water generated in the alkaline water generating electrode chamber 13 is discharged through the opening 2a of the primary partition wall 2 having the upper portion opened, and the secondary electrolytic cell 20 is flown through the flow passage 4.

It is designed to improve the taste of water and to suppress the growth of bacteria through silver activated carbon.

Therefore, the production process of the electrolytic ion water obtainable through the water purifier of the present invention configured as described above is as follows.

First, when the purified water from the purified water flows into the lower portion of the primary electrolytic bath 10 through the inlet 5 of the electrolytic cell 1, the incoming water is gradually filled to the upper side and the positive electrode plate 14 and the negative electrode plate 15 Acid water is generated in the primary acidic water generating electrode chamber 12 between the positive electrode plate 14 and the primary membrane 11 by the power supplied from the power supply unit 40, and is discharged through the acidic water outlet 6. Alkaline water is generated in the alkaline water generating electrode chamber 13 between the primary membrane 11 and the positive electrode plate 15 and exits through the opening 2a of the primary partition wall 2 through the flow path 4. It is introduced below.

Thereafter, the alkaline water flowing downward through the opening 3a of the secondary partition 3 of the secondary electrolyzer 20 is supplied to the anode plate 26 and the cathode plates 27 and 28 through the power supply unit 40. As a result, acidic water is generated in the secondary acidic water generating electrode chamber 23 between the positive electrode plate 26 and the diaphragm 21, joined with the acidic water generated in the primary electrolytic bath 10, and discharged to the acidic water outlet 7. Strong alkaline water is generated between the secondary membrane 21 and the negative electrode plate 27 and between the negative electrode plate 27 and the secondary membrane 22 by the strong alkaline water generation electrode chamber 24 so that the strong alkaline water discharge port is formed. (8) is discharged to be used as the washing water, weak alkaline water is generated in the electrode chamber 25 between the diaphragm 22 and the negative electrode plate 28 is generated through the weak alkaline water outlet (9) for drinking water It is to be used.

Therefore, even in the secondary electrolytic bath 20, the electrolysis takes place in the weak alkaline water gradually filled from the bottom to the top, thereby enabling stable electrolysis, and sufficient exchange of ions through the diaphragm due to sufficient time.

Therefore, the water purifier of the present invention measures the flow rate of the inflow water through the flow sensor 33 so that the proper electrolysis in the electrolytic unit is always constant by controlling the applied voltage at the control unit 39 according to the flow rate of the inflow water. .

That is, in the controller 39, when the flow rate value is small, the flow rate of water passing through the electrolyzer 1 is low, so that the voltage applied to the electrolyzer 1 is lowered to reduce the amount of electrolysis. By increasing the amount of electrolysis to increase the pH of the weak alkaline water, strong alkaline water, acidic water regardless of the flow rate flowing into the electrolytic cell (1).

Hereinafter, through the values of <Table 1> and <Table 2> obtained through the following <Example 1>, the water purifier of the present invention through the automatic adjustment of the applied voltage according to the flow rate change of the influent water of weak alkaline water, It can be confirmed that the aliphatic and acidic water can be stably discharged.

<Table 1> and <Table 2> measured through the above-described <Example 1> are measured values when there is no control over the flow rate and when the flow rate is controlled. In the existing water purifier <Table 1> where the voltage applied to the electrolytic cell is constant even if this change is small, the electrolysis becomes strong when the flow rate is low, and the pH of the output water is high. Since the electrolysis characteristics were different, the pH change of the weak alkali water, strong alkali water and acidic water by electrolysis was severe.

On the other hand, in the water purifier <Table 2> of the present invention in which the voltage applied to the electrolyzer is changed according to the flow rate by detecting the inflow amount, the voltage applied to the electrolyzer is increased when the flow rate is high, and the voltage applied to the electrolyzer is low when the flow rate is low. It can be confirmed that constant electrolysis characteristics can be obtained by reducing the pH change of weak alkali water, strong alkali water and acidic water by electrolysis.

On the other hand, the water purifier of the present invention is the amount of electrolyte in the inflow water to the inlet line 43 of the electrolytic unit 1 Electrolyte detection sensor 29 for the detection is further formed so that the electrolyte value of the inflow water measured by the electrolyte detection sensor 29 is input to the control unit 39 so that the control unit 39 according to the change in the electrolyte amount of the inflow water By adjusting the applied voltage at), proper electrolysis in the electrolytic part is always made constant.

In this case, as shown in FIG. 4, the electrolyte detection sensor 29 has a space in which the inflow water can be stored in the center of the body 29a through which the upper and lower sides are penetrated, and the detection pin 29b is inserted therein. have.

At this time, the detection of the electrolyte is to detect the electrolyte through sampling when the power is supplied to the water purifier and the operation stops after use.

At this time, when the sampling of the water purifier is made, the water flows into the electrolyte detection sensor 29 for a predetermined time, and then the water inlet brush 19 is blocked so that the water accumulated in the electrolyte detection sensor 29 is stable. When the voltage is applied to the detection pin (29b) to measure the current flowing across the detection pin to measure the electrolyte amount by the conductivity resistance of the water in the electrolyte detection sensor 29, the lower the electrolyte resistance This is a lot.

At this time, in order to make the amount of electrolysis of the electrolytic cell 1 constant, the current must flow constantly. When the amount of electrolyte in the inflow water is increased through the electrolyte detection sensor 29, the voltage value applied to the electrolytic cell 1 is lowered. On the contrary, when the amount of electrolyte is small, the voltage value applied to the electrolytic cell is increased to keep the electrolysis constant.

Therefore, in the following <Example 2> it can be seen in Table 3 that the water purifier of the present invention can stably obtain high quality weak alkaline water by adjusting the voltage according to the change in the amount of electrolyte in the influent.

Exam conditions:

-Inflow to the electrolyzer: 1.4 L / min, pH of the influent: 7.6

Table 3 shows the electrolysis characteristics according to the change in the amount of electrolyte by measuring the voltage and conduction current applied to the electrolyzer according to the change of electrolyte (flow resistance change) flowing into the electrolyzer and measuring the pH characteristics of each of the extracts. As the amount of electrolyte is small, the value of the conductive resistance is high, and the voltage applied to the electrolytic cell is high.

In addition, it can be seen that the variation of the current characteristics of the electrolytic cell and the pH characteristics of each of the extracts due to the change in the amount of electrolyte was small.

Therefore, according to the above <Example 2>, by detecting the amount of electrolyte contained in the influent water and adjusting the voltage in the electrolytic cell, even if the amount of electrolyte to the influent water is always made constant electrolysis, weak alkaline water, which is a good quality electrolysis output water, Strong alkali water, acidic water can be confirmed that can be obtained.

At this time, the electrolytic water purifier of the present invention is such that the voltage applied to the electrolyzer with respect to the change of the electrolyte is adjusted according to the flow rate flowing into the water purifier. The control range is as follows <Table 4> to <Table 7>.

In addition, the water purifier of the present invention, by controlling a constant extraction ratio of strong alkaline water, acidic water, weak alkaline water by electrolysis to obtain a weak alkaline water containing a large amount of active hydrogen and active minerals of good quality.

That is, by the acidic water control pins 34 formed in the acidic water outlet 6 of the primary electrolyzer 10, the ratio of the amount of the primary acidic water and the alkaline water generated in the primary electrolyzer 10 is determined. The secondary acidic water is discharged out of the primary electrolytic bath 10 to be combined with the secondary acidic water discharged from the secondary electrolytic bath 20, and the alkaline water is introduced into the secondary electrolytic bath 20, and then three ion electrolyzed waters are introduced through electrolysis. Weak alkaline water, strong alkaline water, and acidic water), wherein the secondary acidic water discharged from the secondary electrolyzer 20 is formed of primary acidic water through the acidic water control pin 34 of the primary electrolyzer 10. Combined so that the amount of water discharged through the acid export pin (35) Then, the strong alkaline water discharged from the secondary electrolytic bath 20 is a strong alkali export water pin 36, the weak alkaline water is determined by the pressure loss inside the filter while passing through the post-treatment filter (41).

At this time, the extraction ratio of strong alkaline water: weak alkaline water: acidic water is 1: 1.5 to 2: 1 to 1.1.

At this time, if the strong alkaline water: weak alkaline water: acidic water out of the ratio ratio range of the outgoing electrolytic ion water is severely changed to obtain a stable electrolytic ion water.

Therefore, the amount of discharged water with a ratio of water extraction is determined according to the total flow rate of water flowing into the water purifier, and the amount of water discharged from strong alkali water, weak alkali water and acidic water is shown as <Table 8>.

<Table 8> Output of electrolyzed ionized water determined according to the total inflow of water to the water purifier

Total Inflow [L / min]   Strong alkaline water output [L / min] Weak alkaline water output [L / min] Acid water output [L / min] 0.8 0.2-0.25 0.35-0.4 0.2-0.25 1.0 0.25 -0.3 0.45-0.5 0.25-0.3 1.2 0.3-0.35 0.55-0.6 0.3-0.35 1.4 0.35-0.4 0.65-0.7 0.35-0.4 1.6 0.4-0.45 0.75-0.8 0.4-0.45

Such withdrawal ratio is to confirm that the pH of the alkaline alkaline water outflow from the automatic electrolytic water purifier of the present invention more than pH9.0, pH7.4-8.5 of the strong alkaline water, pH6.9 or less of the acidic water.

Therefore, the withdrawal ratio is to minimize the waste of water of users who do not use the functional water by increasing the amount of water of the weak alkaline water used as drinking water relative to other ionized water.

In addition, the water purifier of the present invention is to prevent the scaling of the electrolytic cell 1 by the plural cleaning method.

That is, the swelling of the electrolytic cell 1 by the plural cleaning method can be prevented, and the electrolytic part skeletal prevention by the plural washing method can prevent the scaling caused by the calcium generated during electrolysis in the electrolytic cell 1. In the conventional method, it was tried to prevent calcium from accumulating inside the electrolyzer by applying reverse power to the electrolyzer during the cleaning mode through periodic repetitive operation of the clean water mode and the clean mode. Considering 20L, there is no cleaning mode even if it is used for 3 ~ 5 days, so calcium builds up inside the electrolytic cell, so that the electrolytic performance decreases and the outlet is clogged. In case of stopping after the operation, it is possible to apply the plural cleaning method to go through the cleaning mode for a certain time. To prevent scaling caused by calcium inside the electrolytic cell does not occur.
