Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ionized water producing apparatus for producing alkaline ionized water or acidic ionized water by electrolyzing water.

[0002]

2. Description of the Related Art Conventionally, as this type of ionized water producing apparatus, one of an electrolytic cell for producing alkaline ionized water and acidic ionized water by electrolyzing water and one of ionized water produced by the electrolytic cell It is known to have a path for discharging the water as generated water and a path for discharging the other ionized water generated by the electrolytic cell as discarded water. In this type of apparatus, water is electrolyzed in an electrolytic cell to generate alkaline ionized water and acidic ionized water, one of the ionized water can be discharged as generated water, and the other ionized water can be discarded.

Further, in this type of apparatus, it is considered that the ionized water discharged as the produced water is selectively changed to alkaline ionized water or acidic ionized water by switching the energizing direction to the electrolytic cell. .

[0004]

However, in this type of apparatus, the ion water different from the desired one may be discharged immediately after switching the energization direction to the electrolytic cell. For example, when acidic ionized water is used and then the energization direction is changed to take in alkaline ionized water, the acidic ionized water that was initially left in the drainage port is discharged. Therefore, there is a possibility that acidic ionized water unsuitable for drinking may be mixed into the taken water. Further, since both of the ionized water are discharged from the same drain port, if the user forgets to switch the energizing direction, he or she may accidentally drink the acidic ionized water.

In view of the above, the present invention can favorably prevent the alkaline ionized water suitable for drinking and the acidic ionized water unsuitable for drinking from being mixed with each other or being mistakenly taken. It was made with the aim of providing a generator.

Means for Solving the Problems and Effects of the Invention The ionized water producing apparatus according to claim 1, which is designed to achieve the above object, produces alkaline ionized water and acidic ionized water by electrolyzing water. The electrolytic cell, a drinking drainage port and a non-drinking drainage port that discharge one of the ionized water generated by the electrolytic cell as generated water, and the other ionized water generated by the electrolytic cell are discharged as discarded water. A drainage path, a switching valve that selectively circulates the one ionized water generated by the electrolyzer to the drinking drainage port or the non-drinking drainage port, and by switching the energizing direction to the electrolytic bath. An energization switching means for selectively converting one of the ionized water into alkaline ionized water or acidic ionized water, and driving the switching valve according to the energization direction to the electrolytic cell, When the ion water is alkaline ionized water, the switching valve to the drinking drainage side, when the one ionized water is acidic ionized water, the switching valve to the non-drinking drain side, respectively. And a switching valve driving means for switching.

In the present invention thus constructed, the electrolyzer produces electrolyzed water to produce alkaline ionized water and acidic ionized water, and one of the ionized water is used as the produced water for drinking drainage or non-drinking drainage.

Further, the switching valve drive means, a switching valve for selectively circulating the one ion water to the drinking drainage port or the non-drinking drainage port,
It is driven as follows in accordance with the direction of energization to the electrolytic cell. That is, when the one ion water is alkaline ion water, it is switched to the drinking drain port side, and when the one ion water is acidic ion water, it is switched to the non-drinking drain port side.

For this reason, when alkaline ionized water is generated as the generated water, the ionized water is always discharged from the drinking drainage port, and when acidic ionized water is generated as the generated water, the ionized water is always the non-drinking drainage water. Each is discharged from the mouth. Therefore, even if water remains in the drain port of the ion water immediately after switching the energization direction to the electrolytic cell, the water is not different ion water. Therefore, alkaline ionized water suitable for drinking and acidic ionized water unsuitable for drinking are
It is possible to satisfactorily suppress mixing with each other. Further, since the drainage port for discharging the alkaline ionized water and the drainage port for discharging the acidic ionized water are different from each other, it is possible to prevent accidental intake of both.

In addition to the configuration of claim 1, the ionized water generator according to claim 2 is further provided on the upstream side of the electrolyzer to add an electrolyte to the water supplied to the electrolyzer. It is characterized by having means. Therefore, in the present invention, the electrolytic cell electrolyzes the water to which the electrolyte has been added. Therefore, in addition to the effect of the first aspect of the invention, there is an effect that the electrolysis can be performed more smoothly, and better alkaline ionized water or acidic ionized water can be taken in.

The ionized water generator according to claim 3 is, in addition to the structure according to claim 1 or 2, further provided on the upstream side of the electrolyzer to adsorb impurities from water supplied to the electrolyzer. It is characterized by having a water purification tank that purifies the water by filtering. Therefore, in the present invention, the electrolytic cell electrolyzes water from which impurities have been removed. Therefore, in addition to the effect of the invention described in claim 1 or 2, there is an effect that it is possible to take in better alkaline ionized water or acidic ionized water having less impurities.

Furthermore, on the bottom plate 3a,

Therefore, the water flowing into the water purification cartridge 19 reaches the upper part of the housing 43 through the space 46 and the gap between the outer periphery of the hollow fiber membrane filter 44 and the inner wall of the housing 43.
Then, through the inside of the hollow fiber membrane filter 44, the drain pipe 4
It is discharged from 4a. The water discharged from the drainage pipe 44a flows into the electrolytic cell 47 through the pipe 56. At this time, when energization (hereinafter referred to as normal energization) is performed so that the tubular electrode 50 serves as an anode and the tubular electrode 51 serves as a cathode, alkaline ionized water is stored in the alkaline ion chamber 53 and acidic ion chamber 54 is formed. Acidic ionized water is generated in each.

Further, the water flowing into the pipe 69 is selectively discharged from the drinking drainage port 6 or the non-drinking drainage port 7 via the flow path switching valve 77.

As shown in FIG. 3, an operation panel 83 is provided on the outer peripheral surface of the side wall 3b. The operation panel 83 includes a purified water switch 83a for instructing the discharge of purified water and an alkaline water switch 8 for instructing the discharge of alkaline ionized water.

The hoses 91 and 92 are the branch plugs 9 attached to the tips of the water discharge pipes 95 of water taps (so-called faucets).
6 is connected. Depending on the operating position of the lever 96a, the branch plug 96 allows the water that has flowed in from the water discharge pipe 95 to be discharged as it is to 97 or to supply the water that has flowed in from the water discharge pipe 95 to the raw water supply port 5 via the hose 91. It is well known that the water flowing from the drinking drainage port 6 through the hose 92 is made to flow out and discharged to 97. The hose 93 is connected to a distributor 98 mounted on the wall of the sink 97. The distributor 98 is a well-known device that discharges the water that has flowed in through the hose 93 from the non-drinking drain port 7 little by little when the water discharge pipe 98a is operated. Further, the tip of the hose 94 lies on the bottom of the sink 97.

FIG. 4 is an explanatory view schematically showing the structure of the water distribution path and the control system in the water treatment device 1.
As described above, the water flowing from the raw water supply port 5 flows into the mineral addition cartridge 17 via the flow rate switching valve 23, and the mineral stone inserted into the space 38 and the calcium added into the calcium addition cylinder 32. Pass through.
Subsequently, the water flows into the water purification cartridge 19 and the space 46
It passes through the activated carbon and the hollow fiber membrane filter 44 inserted into the electrolysis tank 47 and flows into the electrolytic cell 47. At this time, the flow rate sensor 55 detects the flow rate of water.

During normal energization, the water flowing into the electrolytic cell 47 is electrolyzed and alkaline ionized water is discharged from the alkaline discharge port 49a. This water is selectively sent by the electromagnetic valve 67 to a path that flows into the flow path switching valve 77 or a path that is discharged as waste water from the drain port 8 via the pH sensor 73. In addition, when water flows into the flow path switching valve 77, the water flows into a path discharged from the drinking drainage port 6 as drinking water or a path discharged from the non-drinking drainage port 7 as drinking water. It is selectively sent according to the operation of the path switching valve 77. On the other hand, during normal energization, acidic ionized water is discharged from the acidic discharge port 49b, and the electromagnetic valve 7 is discharged.
When 1 is open, the water is discharged as waste water from the drain port 8.

Further, the detection signals of the flow rate sensor 55 and the pH sensor 73, and the signal according to the operation state of the operation panel 83 are the electronic control circuit (E
CU) 99. Based on this signal, the electronic control circuit 99 causes the flow rate switching valve 23, the electromagnetic valves 67, 71,
Liquid crystal display 8 of flow path switching valve 77 and operation panel 83
3f and the electrolytic cell 47 are controlled. Next, the control by the electronic control circuit 99 and the operation of the water treatment device 1 will be described.

(1) Water purification mode: When the water purification switch 83a of the operation panel 83 is operated, the electronic control circuit 99 executes the following control. First, the flow rate switching valve 23 is fully opened, the energization to the electrolytic cell 47 is stopped, the electromagnetic valve 71 is closed, the electromagnetic valve 67 is switched to the flow path switching valve 77 side (pipe 69 side), and the flow path switching is performed. The valve 77 is switched to the drinking drainage port 6 side.

Then, the water passing through the flow rate switching valve 23 comes into contact with the mineral stone in the space 38, but since the flow velocity is high here, the mineral content is hardly added. After calcium is added to the water in the calcium adding cylinder 32 (regardless of this mode), impurities such as chlorine and trihalomethane are removed by the activated carbon in the space 46 and the hollow fiber membrane filter 44, and the water reaches the electrolytic cell 47. Since no current is applied to the electrolytic cell 47 and the electromagnetic valve 71 is closed, the total amount of water flowing into the electrolytic cell 47 is discharged from the alkali discharge port 49a. Since the electromagnetic valve 67 is switched to the flow channel switching valve 77 side and the flow channel switching valve 77 is switched to the drinking drainage port 6 side, the total amount of this water, that is, the total amount of water that has passed through the water purification cartridge 19 is the drinking drainage port. It is discharged from 6. Therefore, when water is discharged from the water discharge pipe 95, the water treatment device 1
Thus, tap water impurities can be removed and discharged from the branch plug 96.

(2) Alkaline water mode: When the alkaline water switch 83b is operated, the electronic control circuit 99 executes the following control. First, the flow rate switching valve 23 is fully opened, the electrolyzer 47 is normally energized, the electromagnetic valve 71 is opened, and the electromagnetic valve 67 is switched to the pH sensor 73 side (pipe 68 side). Then, the water which has passed through the flow rate switching valve 23 is purified by the water purification cartridge 19 after being added with calcium as an electrolysis accelerator in the calcium addition cylinder 32 with almost no mineral added in the space 38. , To the electrolytic cell 47. In the electrolyzer 47, since normal energization is performed, alkaline ion water is generated in the alkaline ion chamber 53 and acidic ion water is generated in the acidic ion chamber 54. The alkaline ionized water is discharged from the alkaline discharge port 49a, and is discharged from the drain port 8 via the electromagnetic valve 67 and the pH sensor 73. Also, the acidic ionized water is discharged from the acidic discharge port 49b, and the electromagnetic valve 7
It is discharged from the drain port 8 via 1. As a result, while observing the pH of the water discharged from the alkaline ion chamber 53, the water can be continuously discarded.

Alkaline ion water does not always exist in the alkaline ion chamber 53 from the beginning, and acidic ion water may exist in the alkaline ion chamber 53 as in the astringent mode described later. Therefore, while discarding water in this manner, the process waits until water of a predetermined pH is discharged from the alkaline ion chamber 53.

When the pH of the water detected by the pH sensor 73 becomes a predetermined alkalinity, the electronic control circuit 99
Switches the electromagnetic valve 67 to the flow path switching valve 77 side and switches the flow path switching valve 77 to the drinking drainage port 6 side.
Then, the alkaline ionized water can be discharged from the branch plug 96. After that, the electronic control circuit 99 temporarily switches the electromagnetic valve 67 to the pH sensor 73 side at a predetermined timing, for example, every time the cumulative value of the flow rate detected by the flow rate sensor 55 increases by 1 liter. And the desired p
The cylindrical electrode 5 so that the alkaline ionized water of H is discharged.
The amount of electricity supplied to 0, 51 is controlled. During execution of this mode, the pH sensor 7 is displayed on the liquid crystal display 83f.
The pH detected in 3 is displayed.

When the ionic strength setting switch 83e is operated and a strong alkali is instructed during execution of this mode, the electronic control circuit 99 drives the flow rate switching valve 23 in the closing direction by a predetermined amount. By this control, the amount of water flowing through the electrolytic cell 47 per unit time can be reduced, and the water can be electrolyzed more favorably. Therefore, strong alkaline ionized water can be discharged with a relatively small electric power without changing the amount of electricity supplied to the electrolytic cell 47.
When a strong alkali is instructed, control for increasing the amount of electricity supplied to the electrolytic cell 47 may also be executed. In this case, stronger alkaline ionized water can be discharged.

(3) Astringent mode: When the astringent switch 83c is operated, the electronic control circuit 99 executes the following control. First, the flow rate switching valve 23 is fully opened, and the electrolyzer 47 is energized in the direction opposite to the normal direction to open the electromagnetic valve 71 and open the electromagnetic valve 6.
7 is switched to the pH sensor 73 side (pipe 68 side). Then, since electricity is supplied in the opposite direction to the normal direction, acidic ionized water is stored in the alkaline ion chamber 53
Alkaline ionized water is generated in each. The acidic ionized water is discharged from the alkali discharge port 49a, and is discharged from the drainage port 8 via the electromagnetic valve 67 and the pH sensor 73.

The electronic control circuit 99 is used in the alkali ion chamber 5
When observing the pH of the water discharged from No. 3, the water is continuously discarded, and when the pH of the water shows a desired acidity, the electromagnetic valve 67 is switched to the flow passage switching valve 77 side and the flow passage switching valve 77 is turned on. Switch to the non-drinking drainage port 7 side. Then
The acidic ionized water (astrinsen solution) can be discharged from the distributor 98.

Also in this mode, the liquid crystal display 83f displays the pH, and the pH of the water is detected at a predetermined timing to control the energization amount. Also, the ionic strength setting switch 83
Even when strongly acidic is instructed by e, the flow rate of water is controlled as in the alkaline water mode.

(4) Mineral water mode: operation panel 83
When the mineral water switch 83d is operated, the electronic control circuit 99 executes the following control. First, the flow rate switching valve 23 is controlled so that the flow rate of water detected by the flow rate sensor 55 becomes a predetermined amount that is set smaller than that in each of the above modes, and the electrolysis tank 47 is energized. Stop, close the electromagnetic valve 71, switch the electromagnetic valve 67 to the flow path switching valve 77 side (pipe 69 side), and switch the flow path switching valve 77.
To the drinking drainage port 6 side.

Then, the water passing through the flow rate switching valve 23 comes into contact with the mineral stone in the space 38, but since the flow velocity is slow here, the mineral content of the mineral stone is sufficiently added to the water.
Subsequently, water is added with calcium in the calcium addition cylinder 32 (regardless of this mode), impurities are removed by the water purification cartridge 19, and the water reaches the electrolytic cell 47. Since the electrolysis tank 47 is not energized and the electromagnetic valve 71 is closed, the total amount of water flowing into the electrolysis tank 47 is discharged from the drinking drainage port 6 through the electromagnetic valve 67 and the flow path switching valve 77. Is discharged. Therefore, the mineral water added with the mineral component can be discharged from the branch plug 96.

As described above, in the water treatment device 1, depending on the operation state of the operation panel 83, purified water, alkaline ionized water,
Of acidic ionized water and mineral water, desired ones can be discharged, and the strength of alkaline ionized water and acidic ionized water can be set. Further, in the water treatment device 1, the flow path switching valve 77 is switched to the drinking drainage port 6 side in the alkaline water mode, and the flow path switching valve 77 is switched to the non-drinking drainage port 7 side in the astringent mode. . Therefore, when alkaline ionized water is generated in the alkaline water mode, the ionized water is always discharged from the drinking drainage port 6, and when acidic ionized water is generated in the astringent mode, the ionized water is discharged from the non-drinking drainage port 7. , Each is discharged. Therefore, even if water remains in the drinking drainage port 6 immediately after switching from the astringent mode to the alkaline water mode and switching the energization direction to the electrolytic cell 47, the water is not acidic ionized water. Similarly, immediately after changing from alkaline water mode to astringent mode,
Even if water remains in the non-drinking drainage port 7, the water is not alkaline ionized water. Therefore, it is possible to favorably prevent the alkaline ionized water suitable for drinking and the acidic ionized water unsuitable for drinking from mixing with each other.

Further, since the drainage port for discharging alkaline ionized water (drinking drainage port 6) and the drainage port for discharging acidic ionized water (non-drinking drainage port 7) are different from each other, it is possible to take water by mistake. Absent. In particular, if the drinking drainage port 6 is connected to the branch plug 96 and the non-drinking drainage port 7 is connected to the distributor 98 as in the above-described use example, the water intake forms of the both are completely different, so that mistakes can be better prevented. it can.

Further, in the water treatment device 1, calcium is added to the water flowing into the electrolytic cell 47 by the calcium addition cylinder 32. Therefore, the electrolysis can be smoothly performed, and good alkaline ionized water or acidic ionized water can be taken in. Further, in the water treatment device 1, since the electrolytic cell 47 electrolyzes the water that has passed through the water purification cartridge 19, it is possible to take good alkaline ionized water or acidic ionized water without impurities.

In the above embodiment, the drain port 8
, The flow path switching valve 77 is a switching valve, the electronic control circuit 99 is an energization switching means and a switching valve driving means, the calcium addition cylinder 32 is an electrolyte addition means, and the water purification cartridge 19 is a water purification tank. Equivalent to.

Furthermore, the present invention is not limited to the above-described embodiments, and can be implemented in various forms without departing from the scope of the present invention. For example, in the above-described embodiment, a path for circulating the water discharged from the alkali discharge port 49a to the pH sensor 73 is provided.
The H sensor 73 may be omitted, and the water discharged from the alkali discharge port 49a may directly flow into the flow path switching valve 77.
In this case, the pH of the ionized water cannot be feedback-controlled, but the ionized water can be generated for the time being. Further, in this case, in order to prevent the acidic ionized water remaining in the path from the alkali ion outlet 49a to the flow path switching valve 77 from being mixed into the alkali ionized water, the flow path switching valve 77 is set as close as possible to the alkali outlet. It is desirable to provide it near 49a.
