As a result, the case 22, that is, the device body 12 is attached and fixed to the tip of the water discharge pipe 21.

On the other hand, as shown in FIG. 1, inside the case projecting portion 24, an electrolytic cell 30 having a double cylindrical shape as a whole is provided. The electrolytic cell 30 is arranged with an outer cylindrical wall portion 31 fitted to the inner peripheral surface of the case protruding portion 24 and a predetermined required space inside the outer cylindrical wall portion 31. Inner tubular wall portion 32 and outer tubular wall portion 31
The cylindrical electrode 33 is arranged along the inner peripheral surface of the inner cylindrical wall portion 32, and the cylindrical electrode 34 is arranged along the outer peripheral surface of the inner cylindrical wall portion 32. A pair of electrodes is composed of the two cylindrical electrodes 33 and 34. Then, the cylindrical electrode 33
A diaphragm 35 made of, for example, a non-woven fabric made of polyester is disposed between the cylindrical electrode 34 and the cylindrical electrode 34.
Thus, the inside of the electrolytic cell 30 is partitioned into two chambers, specifically, an outer alkaline ion chamber 36 and an inner acidic ion chamber 37.

A cartridge chamber 38 is formed inside the inner cylindrical wall portion 32 of the electrolytic cell 30, and a water purification cartridge 39, which is a water purification member, is accommodated in the cartridge chamber 38. In this case, the water purification cartridge 39 is configured to be able to be taken in and out of the cartridge chamber 38 with the lid 25 of the case projecting portion 24 opened. As a result, one unit (specifically, the apparatus main body 12) is obtained by housing the electrolytic bath 30, the water purification cartridge 39, and the branch plug 26 in the case 22.
Is configured. In addition, the water purification cartridge 39
The cartridge case 39a contains, for example, an activated carbon filter 39b and a hollow fiber membrane filter 39c. The lid 25 is the outer tubular wall portion 3 of the electrolytic cell 30.
It is structured such that it is fastened and fixed to the outer peripheral portion of the upper end of 1 by screwing.

The water outflow passage 26a of the branch plug 26
The tap water from is supplied to the water purification cartridge 39 in the cartridge chamber 38 through the electrolysis accelerator addition passage 40. An electrolysis accelerator addition cylinder 41 is housed in the electrolysis accelerator addition passage 40 so as to be removable. In this case, for example, granular calcium glycerophosphate is contained in the electrolysis accelerator addition cylinder 41 as the electrolysis accelerator.

The purified water that has passed through the purified water cartridge 39 and is purified flows as shown by the arrow in FIG. That is, the space between the lid 25 and the outer peripheral portion of the upper portion of the water purification cartridge 39 serves as the water passage 42, and the water passage 42 connects the water purification cartridge 39 and the electrolytic cell 30. The purified water supplied into the electrolytic cell 30 is electrolyzed by applying a DC voltage with the outer cylindrical electrode 33 as a negative electrode and the inner cylindrical electrode 34 as a positive electrode. In this case, as shown in FIG. 1, two lead wires 13a and 13b are accommodated in the connection cable 13, and the respective tip portions of these two lead wires 13a and 13b are connected to each other as shown in FIG.

It is possible to apply a required DC voltage to both the cylindrical electrodes 33 and 34.

By the electrolysis, alkaline ionized water is generated on the alkaline ion chamber 36 side, and
Acid ion water is generated on the side of the acid ion chamber 37. As shown in FIGS. 2 and 4, the alkaline ionized water in the alkaline ion chamber 36 is supplied to the water discharge passage 26c of the branch plug 26 through the alkaline ionized water passage 45, and the water is discharged downward from the water discharge passage 26c. Is configured to be released to.
On the other hand, the acidic ionized water in the acidic ionized chamber 37 passes through the acidic ionized water passage 46 as shown in FIGS.
The acidic ionized water discharge port 47 provided on the lower surface of the left end of the case base 23 discharges downward.

Next, the operation of the above configuration will be described. First,
When tap water is used as it is, as shown in FIG. 3, the switching lever 27 of the branch plug 26 is set to the raw water position A indicated by the solid line. When the tap 20 is opened in this state, tap water (raw water) is discharged from the tap 21 of the tap 20.
After entering the water inflow passage 26a of the branch plug 26, the water flows through the switching valve portion 26d to the water discharge passage 26c side, and is discharged downward from the lower end of the water discharge passage 26c.

When it is desired to use alkaline ionized water, the switching lever 27 is rotated to the ionized water position C (see the chain double-dashed line in FIG. 3). By this operation, the branch plug 26
The switching valve portion 26d is switched so that the tap water (raw water) that has entered from the water inflow passage 26a flows to the water outflow passage 26b side. At the same time, the energizing switch for applying a DC voltage to the cylindrical electrodes 33, 34 of the electrolytic cell 30 is turned on.
If the tap 20 is opened in this state, tap water (raw water)
Enters the water inflow path 26a of the branch plug 26, flows through the switching valve portion 26d toward the water outflow path 26b, and calcium is added through the electrolysis accelerator addition path 40 as shown in FIG. Then, the water is supplied into the water purification cartridge 39.

Subsequently, the tap water supplied into the water purification cartridge 39 passes through the water purification cartridge 39, whereby the activated carbon filter 39b and the hollow fiber membrane filter 39 are supplied.
Purified by c. And the purified water purified is shown in Figure 1.
It flows as shown by the middle arrow and is supplied into the electrolytic cell 30.
The purified water supplied into the electrolytic bath 30 is electrolyzed by applying a DC voltage with the outer cylindrical electrode 33 as a negative electrode and the inner cylindrical electrode 34 as a positive electrode.
By this electrolysis, alkaline ionized water is generated on the alkaline ion chamber 36 side and acidic ionized water is generated on the acidic ion chamber 37 side. Subsequently, the alkaline ionized water in the alkaline ion chamber 36 is supplied to the water discharge passage 26c of the branch plug 26 through the alkaline ionized water passage 45 shown in FIG. 2 and discharged downward from the water discharge passage 26c. . On the other hand, the acidic ionized water in the acidic ionization chamber 37 passes through the acidic ionized water passage 46, and then is discharged downward from the acidic ionized water discharge port 47 of the case base 23.

A water flow sensor (not shown) for detecting the amount of water flowing into the electrolytic cell 30 is provided in the main body 12 of the apparatus, and a predetermined amount (for example, a water flow sensor) is detected based on the detection result of the water flow sensor. (90 liters) The cylindrical electrodes 33 and 34 are automatically cleaned every time water is passed.
In this case, when cleaning the cylindrical electrodes 33 and 34,
It is performed by applying a DC voltage with the energization direction reversed from the normal direction (specifically, the outer cylindrical electrode 33 is used as a positive electrode and the inner cylindrical electrode 34 is used as a negative electrode).

Next, when it is desired to use purified water, the switching lever 27 is rotated to the purified water position B (see the chain double-dashed line in FIG. 3). By this operation, the water inflow passage 26a of the branch plug 26
The switching valve portion 26d is switched so that the tap water (raw water) that has entered from the side flows to the water outflow passage 26b side. In this case, the energizing switch for applying the DC voltage to the tubular electrodes 33, 34 of the electrolytic cell 30 remains off. When the tap 20 is opened in this state, tap water (raw water) becomes
After entering the water inflow passage 26a of the branch plug 26, the switching valve unit 2
After flowing through 6d toward the water outflow passage 26b side, and as shown in FIG. 1, calcium is added through the electrolysis accelerator addition passage 40, and then supplied into the water purification cartridge 39.

Subsequently, the tap water supplied into the water purification cartridge 39 passes through the water purification cartridge 39, whereby the activated carbon filter 39b and the hollow fiber membrane filter 39 are supplied.
Purified by c. And the purified water purified is shown in Figure 1.
It flows as shown by the middle arrow and is supplied into the electrolytic cell 30.
In this case, the purified water supplied into the electrolytic bath 30 is not electrolyzed because no DC voltage is applied to the cylindrical electrodes 33 and 34. Thereafter, the purified water supplied into the electrolytic bath 30 is supplied from the alkali ion chamber 36 side to the water discharge passage 26c of the branch plug 26 through the alkali ion water passage 45 shown in FIGS. 2 and 4. It is discharged downward from the water discharge passage 26c. In this case, a normally-open electromagnetic valve (not shown) is provided in the acidic ion water passage 46 on the acidic ion chamber 37 side, and the electromagnetic valve is closed by being energized. As a result, the purified water supplied into the electrolytic bath 30 is not discharged through the acidic ion water passage 46 on the acidic ion chamber 37 side. The solenoid valve is configured to be energized and closed when the switching lever 27 is rotated to the water purification position B.

And a pair of cylindrical electrodes 33, 34 disposed between the cylindrical wall portions 31, 32, and a water purification cartridge 39 is arranged inside the inner cylindrical wall portion 32 of the electrolytic cell 30. Since it is configured to be installed, the water purification cartridge 39 is housed inside the tubular (double-cylindrical) electrolytic cell 30 as a whole. As a result, the configuration of the apparatus main body 12 can be significantly downsized as compared with the conventional configuration (see FIG. 10), and
Since the installation space required for installing the apparatus main body 12 becomes small, it becomes much easier to install.

In the case of this embodiment, the electrolytic cell 30, the water purification cartridge 39, and the branch plug 26 are housed in the case 22 to form one unit, that is, the device main body 12. Since the branch plug 26 is configured to be attached to the tip of the water discharge pipe 21 of the water source plug 20, the device body 12 of the ion water generator is of a so-called faucet direct connection type, and the hoses 8a and 8b required in the conventional configuration (see FIG. 10) are provided.

In the case of this configuration, as shown in FIG. 9, when the switching lever 57 is pivotally operated to the raw water position P (upper oblique position shown by the solid line), tap water (raw water) entering from the water inflow passage 56a is discharged into the water discharge passage. 56
It is flown as it is to the c side. Further, when the switching lever 57 is operated to rotate to the ion water position Q (a diagonally downward position indicated by the chain double-dashed line), tap water (raw water) entered from the water inflow passage 56a is made to flow to the water outflow passage 56b side. Has been done.

A diaphragm 64 made of, for example, a polyester non-woven fabric is disposed between the cylindrical electrode 62 and the cylindrical electrode 63. The diaphragm 64 allows the inside of the electrolytic cell 59 to be two chambers, specifically, Is partitioned into an inner alkaline ion chamber 65 and an outer acidic ion chamber 66.

A cartridge chamber 67 is formed inside the inner cylindrical wall portion 61 of the electrolytic cell 59, and a water purification cartridge 68, which is a water purification member, is accommodated in the cartridge chamber 67. In this case, the water purification cartridge 68 is configured to be able to be taken in and out of the cartridge chamber 67 with the lid member 55 of the case main body 54 opened. As a result, by housing the electrolytic bath 59, the water purification cartridge 68, and the branch plug 56 in the case 52, one unit (specifically, the device main body 5

The cartridge case 68a contains, for example, an activated carbon filter 68b and a hollow fiber membrane filter 68c. The lid member 55 is configured to be screwed and fixed to the outer peripheral portion of the left end of the outer tubular wall portion 60 of the electrolytic cell 59.

The water outflow passage 56b of the branch plug 56
As shown in FIG. 7, the tap water from is supplied into the electrolytic cell 59 from the left end of the outer cylindrical wall portion 60 of the electrolytic cell 59. In this case, the tap water entering from the left end of the outer tubular wall portion 60 is the space portion 55a on the inner surface side of the lid member 55.

By the above electrolysis, alkaline ionized water is generated on the alkaline ion chamber 65 side, and
Acidic ion water is generated on the acidic ion chamber 66 side. As shown in FIG. 8, the alkaline ionized water in the alkaline ion chamber 65 is configured to be supplied into the purified water cartridge 68 through the water passage 72 which is a space on the right end side of the purified water cartridge 68. ing. In this case, a pressure adjusting device 73 is provided on the closing wall portion 60a that closes the right end side of the outer tubular wall portion 60, as shown in FIG. By rotating the adjusting knob 74 of the pressure adjusting device 73, an appropriate pressure is applied to the acidic ion water in the acidic ion chamber 66, and at the same time, to the alkaline ion water in the alkaline ion chamber 65. Also has a configuration in which the same appropriate pressure as above is applied. This pressure allows the alkaline ionized water to smoothly pass through the water purification cartridge 68. As shown in FIG. 8, the side wall portion 60a is adjacent to the pressure adjusting device 73 and the pressure switch 7 is provided.
5 are provided. The pressure switch 75 is an energizing switch for applying a DC voltage to the tubular electrodes 62 and 63 of the electrolytic cell 59, and is provided in the acidic ion chamber 66, that is, the electrolytic cell 5.
It is configured to turn on when the water pressure in 9 becomes equal to or higher than the set pressure.

After the alkaline ionized water is purified by passing through the activated carbon filter 68b and the hollow fiber membrane filter 68c in the water purification cartridge 68, it is formed on the lid member 55 as shown in FIGS. 7 and 8. Further, the alkaline ionized water passage 76 is discharged downward through the outlet at the lower end thereof. On the other hand, the acidic ionized water in the acidic ion chamber 66, as shown in FIG.
After passing 3, the acidic ionized water outlet 77 is discharged downward.

Next, the operation of the second embodiment will be described. First, when tap water is used as it is, as shown in FIG. 9, the switching lever 57 of the branch plug 56 is set to the raw water position P shown by the solid line. In this state, tap 20
When the water is opened, tap water (raw water) enters the water inflow path 56a of the branch plug 56 from the water discharge pipe 21 of the water tap 20, and then flows through the switching valve portion to the water discharge path 56c side. It is discharged downward from the lower end of the discharge path 56c.

When using alkaline ionized water, the switching lever 57 is rotated to the ionized water position Q (see the chain double-dashed line in FIG. 9). By this operation, the branch plug 56
The switching valve unit is switched so that the tap water (raw water) that has entered from the water inflow passage 56a flows to the water outflow passage 56b side. When the tap 20 is opened in this state, tap water (raw water) becomes
After entering the water inflow passage 56a of the branch plug 56, the water flows through the switching valve portion to the water outflow passage 56b side, and as shown in FIG. 7, the electrolysis is performed while diffusing in the space portion 55a on the inner surface side of the lid member 55. It is supplied into the tank 59. At this time, the tap water is covered with the lid member 55.
When the tap water enters the electrolysis accelerator addition cylinder 69 via the communication hole 69a when diffusing in the space 55a of
Calcium is added to the tap water.

When the tap water is sufficiently supplied into the electrolytic cell 59 to increase its pressure, the pressure switch 75 is turned on to make the outer cylindrical electrode 62 of the electrolytic cell 59 a positive electrode and the inner cylindrical shape. A DC voltage is applied with the electrode 63 as a negative electrode. As a result, the tap water supplied into the electrolytic bath 59 is electrolyzed to generate alkaline ion water on the side of the alkaline ion chamber 65 and acidic ion water on the side of the acidic ion chamber 66. Then, the alkaline ion chamber 6
As shown in FIG. 8, the alkaline ionized water in 5 is supplied to the inside of the water purification cartridge 68 through the water passage 72, and by passing through this water purification cartridge 68, it is purified by the activated carbon filter 68b and the hollow fiber membrane filter 68c. To be done. Then, the purified alkaline ionized water passes through the alkaline ionized water passage 76 of the lid member 55 and is discharged downward from the outlet at the lower end thereof. On the other hand, the acidic ionized water in the acidic ion chamber 66, as shown in FIG.
After passing 3, the acidic ionized water outlet 77 discharges downward. The configuration other than the above is almost the same as the configuration of the first embodiment.

Also in the second embodiment having such a structure, it is possible to obtain substantially the same operational effects as in the first embodiment. In particular, in the case of the second embodiment, since tap water is first supplied into the electrolytic cell 59 for electrolysis and only alkaline ionized water is passed through the water purification cartridge 68 for purification, The life of the cartridge 68 can be extended to about twice as long as that of the first embodiment.

In the above embodiment, when it is desired to purify and use the acidic ionized water, the energizing direction changeover switch among various operation switches provided in the power supply unit 14 is operated. As a result, the cylindrical electrode 6 on the outer side of the electrolytic cell 59 is
The energization direction is switched so that a DC voltage is applied with 2 being the negative electrode and the inner cylindrical electrode 63 being the positive electrode. Then, in this energization switching state, the switching lever 57 is rotated to the ion water position Q (see the chain double-dashed line in FIG. 9) in the same manner as in the case where it is desired to use the alkaline ionized water, and the tap is opened. For example, the alkali ion water passage 7 of the lid member 55
The purified acidic ionized water is released from 6. At this time, unpurified alkaline ionized water is released from the acidic ionized water passage 77.

Further, in the second embodiment, even if dirt such as metal peeled off from the electrodes 62 and 63 is mixed into the ionic water at the time of cleaning the electrodes, either the alkaline ionic water or the acidic ionic water is used. That is, since the ion water to be used is purified by passing it through the water purification cartridge 68, it is possible to prevent the ion water to be used from being contaminated with metal or the like.
