It is something to maintain. A flow rate sensor 172 is connected to the constant flow rate valve 171 via a water pipe 163,
The flow rate sensor 172 functions to integrate the tap water flowing through the water supply pipe 163, that is, the tap water supplied to the electrolytic ion water generator 100. In addition, the start of the flow of tap water flowing through the flow rate sensor 172 is detected, and a detection signal from the flow rate sensor 172 is sent to control means (not shown), and the control means is paired with the electric field tank 150 described later. A DC power supply device 180, which will be described later, is controlled so as to start energizing the electrodes. Also,
A check valve 173 for preventing backflow is connected to the flow sensor 172 via a water supply pipe 164. A water pipe 165 is connected to the check valve 173.
Is branched into a water supply pipe 165a and a water supply pipe 165b, the water supply pipe 165a is further branched into water supply pipes 166a and 166b, and the water supply pipes 166a and 166b are connected to the bottom wall of the electrolytic cell 150. .

A pair of electrodes 151 and 152 are spaced apart from each other in the electrolytic cell 150, and a polyester nonwoven fabric is coated with polyethylene chloride between the pair of electrodes 151 and 152. A diaphragm 153 is provided, and a first tank 154 and a second tank 155 that are partitioned by the diaphragm 153 are provided.
The water supply pipe 166a is connected to the first tank 154, and the water supply pipe 166b is connected to the second tank 155. Further, a water distribution pipe 168 connected to a discharge port 168a for discharging the ion water in the first tank 154 to the outside is connected to the upper part of the first tank 154 of the electrolysis tank 150, and the drain pipe 168 is electromagnetically connected. The valve 174 is connected. Further, a solenoid valve 175 which is in a normally closed state is connected to the water supply pipe 165b, a drain pipe 169 is connected to the solenoid valve 175, and the drain pipe 169 is a drain located downstream of the solenoid valve 174. It is connected to the pipe 168.

A water pipe 167 is connected to the upper part of the second tank 155, and the water pipe 167 is connected to the switch 110.
The ion water in the second tank is connected to the water pipe 1
When the water is sent to the switch 110 via 67 and the flow path is switched to the water injection port 113 side by the switch lever (not shown), the ion water is injected into the container (not shown) or the like via the water inlet 113. is there.

A DC power supply device 1 is provided on the pair of electrodes.
It is connected to a terminal having a predetermined polarity of 80. In the figure, the electrode 151 disposed in the first tank 154 is connected to the positive electrode terminal, and the electrode 152 of the second tank 155 is connected to the negative electrode terminal.

Next, the operation of the electrolytic ion water generator 100 will be described. First, a case of generating electrolytic ion water will be described.

In this case, a switch lever (not shown) of the switch 110 is operated to connect the water supply pipe 111 and the water supply pipe 160, and after switching the water supply pipe 167 and the water injection port 113 to communicate with each other, not shown. Open the tap. Then, the tap water is sent to the water purifier 120 via the water pipe 160, where chlorine, mold odor, etc. present in the tap water, that is, contained in the tap water, is activated carbon, and E. coli or other miscellaneous bacteria are blown by the hollow fiber membrane. It is removed and sent to the calcium addition container 140, where the calcium component is added. Then, the water is supplied to the flow rate sensor 172 through the constant flow rate valve 171 via the water supply pipe 162. Flow sensor 172
When tap water starts to flow, the flow rate sensor 172 detects it and sends a detection signal to the control means, and the control means controls the power supply device 180 to start energizing the electrodes 151 and 152. The tap water sent to the flow sensor 172 passes through the check valve 173 and the water pipe 165 and the water pipe 165a to the water pipes 166a and 166b because the electromagnetic valve 175 is closed at this time. Water is split and sent to the first tank 154 and the second tank 155 of the electric field tank 150.

When tap water flows into the electric field tank 150, the tap water is electrolyzed in the electric field tank 150. As shown in the figure, the electrode of the first tank 154 is positive and the electrode of the second tank 155 is positive. Because of the negative polarity, acidic ionized water is generated in the first tank 154 and alkaline ionized water is generated in the second tank 155. The acidic ionized water generated in the first tank 154 is drained to the outside through the water pipe 168 because the electromagnetic valve 174 is in the open state. In addition, the alkaline ionized water generated in the second tank 155 is the water pipe 1
Water is sent to the switch 110 via 67 and is poured from a water injection port 113 into a container or the like (not shown).

In the above case, the case where the use of alkaline ionized water is desired has been described. Conversely, when the use of acidic ionized water is desired, the polarity of the electrodes 151 and 152 can be reversed. The acidic ionized water can be obtained from the water port 113.

Next, a case will be described in which tap water is purified without producing ionized water and water in a state in which calcium is added is desired. In this case, the solenoid valve 174 was operated to be closed, and the water supply pipe 111 and the water supply pipe 160 were made to communicate with each other by a switching lever not shown, and the water supply pipe 167 and the water injection port 113 were made to communicate with each other. Then, open the tap not shown.

Then, as in the case of producing the ionized water, tap water is sent to the water purifier 120, and the water purifier 1
In addition to removing chlorine, musty odor, organic matter, etc. in 20, Escherichia coli or other miscellaneous bacteria are removed, and then water is sent to the calcium addition container 140, after the calcium content is added, it is sent to the electrolytic cell 150 and then the water supply pipe 167. The water is sent to the switch 110 via the water injection port 113 and injected into a container or the like (not shown) from the water injection port 113.

Next, when used to some extent, the electrode 15
Since No. 2 has a negative polarity, calcium contained in tap water sent into the electric field tank 150 is absorbed by the electrode 152.
It is necessary to remove the adhering calcium because it adheres to the water and reduces the electrolysis ability, but in this case, for example, after performing the same operation as in the case of generating the above-mentioned ion water, close the tap not shown. The tap water supply is stopped and the tap water in the electrolytic cell 150 is stored. In this state, the electrode 1
When the polarities of 51 and 152 are reversed and electricity is applied for a predetermined time, the calcium attached to the electrode 152 dissolves in the stored water by the electrolysis action. In this state, the solenoid valve 1
When the valve 75 is opened, the position of the solenoid valve 175 is located below the bottom wall of the electrolytic cell 150. Therefore, the water from which calcium has been dissolved is used as the water supply pipes 166, 166b and the water supply pipe 1.
Water can be drained to the outside from the drain port 168a via 65a, 165b, the solenoid valve 175, the drain pipe 169 and the drain pipe 168. In this way, the calcium attached to the electrode 152 is removed.

[0015]

By the way, the above-mentioned conventional electrolytic ion water generator has the following problems. That is, the first problem is that since the water purifier 120 is located upstream of the electrolyzer 150, all tap water sent to the electrolyzer 150 passes through the water purifier 120, that is, the filter made of hollow fiber membranes. As a result, the integrated flow rate increases and the filter becomes dirty in a short period of time. Therefore, there is a problem that the filter has to be frequently washed, which is troublesome in use, and the life of the filter is shortened, which requires a troublesome replacement work and is also economically unfavorable. The second problem is that since the water purifier 120 is located on the upstream side of the electrolytic cell 150, ion water remains in the electrolytic cell 150 and the water supply pipe 167 between the electrolytic cell 150 and the switch 110. Since the residual ionized water has chlorine that has a bactericidal action removed, it will be used at intervals, and if there is a situation where bacteria etc. will multiply in this residual water, this bacteria will be injected along with the ionized water. The problem is that it is not preferable.

[0017]

Inside the water purifier 20, as described above, a hollow fiber membrane is prepared by mixing a hydrophilic hollow fiber membrane (not shown) and a hydrophobic hollow fiber membrane (not shown) for removing Escherichia coli or other miscellaneous bacteria contained in tap water at a predetermined ratio. Although the filter is stored, the reason why the hydrophobic hollow fiber membrane is mixed is as follows. That is, when tap water is electrolyzed in the electrolysis tank 50 during generation of ion water, oxygen gas and hydrogen gas are generated, and the ion water mixed with the oxygen gas and hydrogen gas generated in the electrolysis tank 50 is purified water. In the case of the water purifier 2
0 through the pores of the hollow fiber membrane, but when the filter is a hydrophilic hollow fiber membrane only, the pores formed in this hollow fiber membrane are blocked by water, Oxygen gas and hydrogen gas cannot pass, and as a result, the flow of water becomes poor and the water purification capacity decreases, and the internal pressure in the electrolytic cell 50 becomes high. The flow of water into the water is suppressed, and as a result, the ability to generate ionized water is reduced. However, in the case of a hydrophobic hollow fiber membrane, the pores are not blocked by water,
Since the oxygen gas or the hydrogen gas can pass through the pores and thus does not hinder the flow of water, when the hydrophobic hollow fiber membrane is mixed, it is possible to prevent the reduction of the water purification capacity. Further, since the oxygen gas and hydrogen gas in the electrolytic cell 50 can pass through the pores of the hydrophobic hollow fiber membrane, the electrolytic cell 50
The internal pressure does not increase, the flow of water into the electrolytic cell 50 is not suppressed, and therefore, the decrease in the ion water generation capacity can be prevented.

Next, the water channel structure of the switch 10a will be described with reference to FIGS. First, when tap water is used as it is, the switching lever 10 shown in FIG.
Operate b to switch to the tap water display position (not shown).
Then, the intake 11 and the faucet 12a are connected so as to communicate with each other through a water passage S1 formed in a switching valve (not shown). In this state, tap water flows into the intake 11 from the faucet 3 of the faucet 2 and passes through the water passage S1. And flows out from the tap 12a. Also,
When tap water is used in a dispersed state, the switching lever 10b is operated to switch to a shower display position (not shown). Then, as shown in FIG. 3, the intake port 11 and the shower port 12b are connected so as to communicate with each other through the water channel S2,
In this state, tap water flows into the intake 11 from the faucet 3 of the faucet 2 and flows out of the shower port 12b via the water passage S2. Next, when using ionized water, switch lever 1
When 0b is switched to the ion water production display position (not shown), the intake valve 11 and the water supply port 14 are formed by the water passage S3, and the inflow port 15 and the water passage opening 16 are formed by the water passage S4 as shown in FIG. Furthermore, the waterway mouth 17
And the water inlet 13 are connected by a water passage S5 so as to communicate with each other. And, in this state, the tap water is the tap 2
From the faucet 3 into the intake 11, then through the water passage S3, from the water supply port 14 to the water supply pipe 61, through the filter device 30 and the calcium addition container 33 to the electrolytic cell 50, where the ions are electrolyzed. It is treated as water, and then flows into the inflow port 15 via the water pipe 67, and the water channel S
4, flowed into the water purifier 20 through the water channel 16 and the inflow connection pipe 21, passed through the hollow fiber membrane housed in the water purification device 20, passed through the outflow connection pipe 22, the water channel opening 17 and the water channel S5 and illustrated from the water injection port 13 Not filled with water.

Next, when cleaning the filter in the water purifier 20, that is, for cleaning the hollow fiber membranes to remove dirt, by operating the switching lever 10b as shown in FIG. 5 to switch to a cleaning display position (not shown), At this time, the intake valve 11 and the water channel 17 are connected by the switching channel so that the water channel S6 and the water channel 16 and the inflow port 15 are connected by the water channel S7. In this state, the tap water flows from the faucet 3 of the faucet 2 into the intake 11, flows into the water purifier 20 through the water channel S6, the water channel 17 and the inflow connection pipe 21, and the hollow fibers stored in the water purifier 20. Outflow connection pipe 2 through the membrane
2, water channel 16, inflow port 15, water supply pipe 67 and drain pipe 6
It is drained from the drain port 19 through 9a and 69b. In other words, the tap water is made to flow in the hollow fiber membrane in the water purifier 20 in the opposite manner to the case where the ion water is generated, whereby the dirt attached to the pores of the hollow fiber membrane is removed and washed.

Next, the operation of the electrolytic ion water generator 1 will be described. First, the case of generating ionized water will be described.

In this case, the switching lever 10b is operated to switch the switching device 10a to the ion water production display position. In this state, the water channel structure of the switching device 10a is as shown in FIG.

Then, the flow rate sensor 7 is passed through the constant flow valve 71 via the water supply pipe 62a and the water flow pipe 62b.
Water is sent to 2. When tap water starts to flow to the flow rate sensor 72, the flow rate sensor meter 72 operates in response to this, the detection signal is sent to the control means, and the control means causes the power supply device 8 to operate.
0 is controlled to start energizing the electrodes 51 and 52. Since the electromagnetic valve 75 is normally closed, the tap water sent to the flow rate sensor 72 is divided into the water supply pipe 63 through the check valve 73 and the water supply pipes 64a and 64b through the water supply pipe 63a. Water is supplied to the first tank 54 and the second tank 55 of the electrolytic tank 50.

When tap water flows into the electrolytic cell 50, the tap water is electrolyzed in the electrolytic cell 50. As shown in the figure, the electrode of the first tank 54 is positive and the electrode of the second tank 55 is Because of the negative polarity, acidic ionized water is generated in the first tank 54 and alkaline ionized water is generated in the second tank 55. The acidic ionized water generated in the first tank 54 is drained to the outside from the drain port 19 through the drain pipe 65a, the solenoid valve 74, and the drain pipe 65b because the solenoid valve 74 is open. . Further, the alkaline ionized water generated in the second tank 55 passes through the water supply pipe 66, the check valve 77 and the water supply pipe 67, the inflow port 15 of the switch 10a, the water passage S4,
Water is sent into the water purifier 20 through the water passage port 16 and the inflow connection pipe 21, and the alkaline ionized water passes through the hollow fiber membrane housed in the water purifier 20 to flow out the connection pipe 22, the water passage port 17, and the water passage. After S5, it flows out from the water injection port 13 and is injected into a container or the like (not shown). When the alkaline ionized water passes through the hollow fiber membrane, Escherichia coli or other bacteria present in the alkaline ionized water are removed by the hollow fiber membrane.

The water purifier 20 is the electrolyzer 50.
Since it is provided on the downstream side of, i.e., immediately before the water injection port, only the desired ion water (alkaline ion water in the case of use) to be used is the water that passes through this water purifier 20 when ion water is generated. Therefore, undesired ionized water (acidic ionized water in the case of Example) does not pass through, and therefore, the amount of water passing through the hollow fiber membrane can be reduced, thus suppressing contamination of the hollow fiber membrane. It is possible to reduce the number of troublesome cleanings of the hollow fiber membrane. Further, since it is possible to prevent the hollow fiber membrane from deteriorating the filter performance, it is possible to reduce the number of times the water purifier 20 is replaced, which is economical. Further, since the water purifier 20 is provided on the downstream side of the electrolysis tank 50, that is, immediately in front of the water injection port 13, for example, water remaining in the electrolysis tank 50 or the water supply pipe 67 at a certain interval is temporarily mixed with bacteria. Even if the water etc. propagates, the residual water always passes through the water purifier 20 during use, and these bacteria are removed by the hollow fiber membrane, which is hygienic.

In the hollow fiber membrane in the water purifier 20, since the hydrophilic hollow fiber membrane is mixed with the hydrophobic hollow fiber membrane in a predetermined ratio, oxygen gas and hydrogen gas generated during electrolysis are generated. Flows out from the water injection port 13 through the pores of the hydrophobic hollow fiber membrane, so that it is possible to prevent the reduction of the water purification capacity,
Further, since the oxygen gas and the hydrogen gas flow out from the water injection port 13, the internal pressure of the electrolytic cell 50 does not rise, the flow of water flowing into the electrolytic cell 50 is not suppressed, and the ion water is generated. A decline in ability is prevented.

In the above case, the case where the use of alkaline ionized water is desired has been described. On the contrary, when the use of acidic ionized water is desired, the polarity of the electrodes 51 and 52 is reversed so that the acidic acidic water is used. Ionic water can be obtained.

Drain pipe 65a, solenoid valve 78, drain pipe 65
It is discharged from the drainage port 19 to the outside via b. At this time, the solenoid valves 74 and 75 are closed and the check valve 7
Since tap water 7 is provided, tap water does not flow into the electrolytic cell 50. Then, the hollow fiber membrane is washed by tap water poured from the opposite direction, and the dirt attached to the pores of the hollow fiber membrane is removed by the water flow.

Next, the electrolytic ionized water generator 1 can be used as a water purifier to obtain purified water by removing bacteria such as tap water and chlorine odor without producing ionized water. The case will be described. In this case, the switching lever 10b is switched to the ionized water generating position so that the water channel structure of the switching device 10a is as shown in FIG.

By this, chlorine, musty odor, organic substances, etc. are removed, and when passing through the calcium addition container 33, the calcium content is added. Then, through the constant flow valve 71, the flow sensor 72, and the check valve 73, the water pipe 63, the water pipe 63
The water is sent to the first tank 54 and the second tank 55 of the electrolysis tank 50 after being split into the water supply pipes 64a and 64b through a. Electric field tank 5
The tap water flowing into 0 is not electrolyzed in the electric field tank 50, passes through the water pipe 66, the check valve 77, the water pipe 67, the inflow port 15 of the switching device 10a, the water channel S4, and the inflow connection pipe 21. The hollow fiber membrane in the water purifier 20 removes Escherichia coli or other germs contained in the tap water into the water purifier 20 and injects water into the container (not shown) from the water injection port 13.

Next, when used over a long period of time, of the pair of electrodes 51 and 52, calcium is attached to the electrode used as a negative electrode, that is, the electrode 52 in FIG. However, the case of removing the adhered calcium, that is, cleaning the electrode will be described. In this case, first, the switching lever 10b
Is switched to the ion water generation display position to make the water channel structure of the switch 10a as shown in FIG. 5, the faucet 2 is opened and tap water is sent to the electrolyzer 50 to store the water, and then the faucet 2 is closed, and then the electrode 51. 1 and 52 have opposite polarities, that is, in FIG. 1, the negative electrode terminal of the DC power supply device 80 is connected to the electrode 51 and the positive electrode terminal is connected to the electrode 52, and electricity is supplied for a predetermined time. Then, as the water in the electrolytic cell 50 is electrolyzed, the calcium that has adhered to the electrode 52 begins to dissolve in the water due to the electrolysis action.
Removed from Then, a switch (not shown) is operated to open the solenoid valves 75 and 78, whereby the electrolyzer 5
Calcium of 0 melted and water was sent to water pipe 63a and drain pipe 6
3b, the solenoid valve 75, the drain pipe 69a, the solenoid valve 78, and the drain pipe 69b are drained from the drain port 19, and the calcium cleaning of the electrode 52 is completed.

Next, tap water can be taken out of the switching device 10a and used as it is. First, when tap water is taken out from the faucet 12a of the switching device 10a and used as it is, the switching lever 10b is used. The switch is switched to the faucet position, and the water channel of the switch 10a is configured as shown in FIG. Then tap water 2 to open tap water

b is switched to the shower position, and the water passage of the switch 10a is configured as shown in FIG. Then, when the faucet 2 is opened, tap water is supplied to the faucet 3 of the faucet 2, the intake 11 of the switch 10a, and the water passage S.
2 and flows out from the shower port 12b.

In the above embodiment, the filter device 30 having activated carbon stored therein is provided integrally with the calcium addition container 33 in the main body 1a, but the filter device 30 should be replaced relatively frequently. Therefore, a case in which the filter device 30 is integrated with the water purifier 20 and is detachably provided on the switching device 10a will be described with reference to FIG. The same parts as those in the above embodiment are designated by the same reference numerals and the description thereof will be omitted.

Further, the outflow connection pipe 22 of the water purifier 20 is connected to the water injection port 13 via the water passage S5. Then, when producing the ionized water, when the faucet 2 is opened, tap water flows into the filter 30 through the faucet 3 and the water passage S8, and chlorine, musty odor, organic matter and the like are removed by the activated carbon, and then the water passage S9,

The cumulative amount of water passing through the vessel 20 can be reduced, and the hollow fiber membrane, that is, the filter can be prevented from being contaminated and clogged. Further, when the usage period is extended, there is a possibility that Escherichia coli or other miscellaneous bacteria may propagate in the residual water remaining in the electrolytic cell 50 and the water supply pipe 67 provided downstream of the electrolytic cell 50. As a result, this residual water will always pass through the water purifier 20, and these Escherichia coli and other miscellaneous bacteria will be reliably removed by the hollow fiber membrane housed in the water purifier 20, and hygienic ionized water will be obtained.

Since the flow can be maintained well, it is possible to prevent the reduction of water purification capacity. Further, since the oxygen gas and the hydrogen gas can be discharged to the outside from the pores of the hydrophobic hollow fiber membrane, the internal pressure of the electrolytic cell 50 does not rise, and therefore the electrolytic cell is caused by the increase of the internal pressure. 5
