Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrolytic ion water generator for generating electrolytic ion water, that is, alkaline ion water or acidic ion water.

[0002]

2. Description of the Related Art Conventionally, an electrolytic ion water generator for electrolyzing tap water or the like to generate alkaline ion water and acidic ion water has been widely used. As shown in FIG. 10, this conventional electrolytic ionized water generator has a diaphragm 1 disposed between a pair of electrodes 101 and 102 provided separately from each other.
First tank 104 and second tank 10 partitioned by 03
5 is provided, and a water purifier 10 connected to the electrolytic bath 100 via a water supply pipe 107.
8 is provided, and the water purifier 108 is connected to a faucet (not shown) such as a water supply (hereinafter simply referred to as a water supply) via a water supply pipe 109.

Then, in a state where power is supplied from a power supply device 106 for supplying a direct current to the pair of electrodes 101, 102 arranged in the electrolytic cell 100, a tap for water is supplied through a water pipe 109 and a water purifier 108. Water is sent to the electrolytic cell 100, and this tap water is electrolyzed to generate electrolytic ion water. When the tap water passes through the above, the activated carbon and the hollow fiber membrane stored in the water purifier 108 have begun to remove chlorine, mold odor, organic matter, Escherichia coli and other miscellaneous bacteria contained in the tap water. There is.

The ionic water (acidic ionic water in the figure) generated in the first tank 104 is drained from a drain pipe 110 connected to a drain port 104a provided in the upper portion of the first tank 104. Ionized water generated in the second tank 105 (alkaline ionized water in the figure)
Is injected through a water injection pipe 111 connected to a water supply port 105a provided in the upper part of the second tank 105.

Further, in the above conventional electrolytic ion water generator, in addition to the use as an ion water generator for generating ion water as described above, it is contained in tap water instead of generating ion water. It also has a use as a purified water generator for purifying tap water by removing chlorine, odor, organic matter and other germs. When used as the water purifier, tap water is supplied from the water pipe 109 to the water purifier 108 without supplying power to the electrodes 101 and 102 of the electrolyzer 100, and the water is purified in the water purifier 108. The purified tap water is poured into a container or the like (not shown) from the water injection pipe 111 via the electrolytic bath 100.

[0006]

By the way, in the above-mentioned conventional electrolytic ion water generator, since the water purifier 108 is provided on the upstream side of the electrolytic cell 100 with respect to the flow of tap water, Even when water is purified, tap water always passes through the electrolyzer 100 after passing through the water purifier 108, the water channel becomes long, and when the electrolyzer 100 is empty, the electrolyzer 100 is filled. Since the water is not sent between the cleaning stations, it takes a long time to obtain the purified water, and the purified water remains in the electrolytic cell 100, and the purified water is not used. Therefore, the efficiency of the purified water is not good. Further, if a part of the purified water remains in the electrolyzer 100 or the like and the usage period is extended, there is a problem that various bacteria and the like propagate in the residual water.

[0007]

In order to solve the above-mentioned conventional problems, the present invention according to claim 1 provides a method for supplying water from a water supply section through an inflow pipe having an intake port and a water supply port and communicating with the intake port.

And a water purifier that purifies the ionic water sent from the electrolysis tank and that supplies the ionic water to the water inlet through a water pipe connected to the outlet. In the vessel, a bypass water pipe for bypassing the inflow pipe communicating with the inlet of the electrolyzer and the water pipe communicating with the water supply port is provided, and the bypass water pipe is selected as either the inflow pipe or the water pipe. To communicate The electrolytic ion water generator is provided with a path switching means, and the invention according to claim 2 takes in water from the water supply section via a water supply pipe having an inflow port and an outflow port and communicating with the inflow port. Along with this, there is a water purifier that purifies this water and sends it out through an inflow pipe that communicates with the outlet, an intake that communicates with the inflow pipe, and a water outlet that sends out ion water.

An electrolytic ionized water generator with a branch of a purified water transmission pipe communicating with a water injection port in an inflow pipe communicating with the water pipe and a channel switching means for selectively switching the flow passage between this water pipe and the purified water transmission pipe Is.

[0008]

Since the invention of claim 1 and the invention of claim 2 are respectively configured as described above, when tap water is used after being purified, the purified water flowing out of the water purifier passes through the electrolytic cell. Since it is directly sent to the water injection port without any treatment, it is possible to obtain purified water in a short time and improve the purification efficiency.
Further, it is possible to eliminate the fact that purified water remains in the electrolytic cell.

Water is injected from a water injection port 13 into a container (not shown) or the like via 17 and the water passage S3.

The water channel structure of the switch 10 when tap water is purified without generating ion water is the same as the water channel structure when generating ion water, that is, as shown in FIG.

Next, when tap water is used as it is, the switching lever 10b shown in FIG. 2 is operated to switch to a tap water display position (not shown). Then, as shown in FIG. 4, the intake 11 and the faucet 12 are connected so as to communicate with each other through a water passage S4 formed in a switching valve (not shown). And
In this state, tap water flows from the faucet 3 of the faucet 2 into the intake 11 and directly flows out of the faucet 12 of the switch 10 through the water passage S4. When tap water is used in a dispersed state (not shown), the switch lever 10b can be operated to switch to a shower display position (not shown), and tap water can be discharged in the form of a shower from a shower port (not shown).

Next, the filter 20b in the water purifier 20
That is, when the hollow fiber membrane is cleaned to remove dirt, the switching lever 10b is operated as shown in FIG. 5 to switch to a cleaning display position (not shown). At this time, the switching valve opens the intake port 11 and the water passage port. 17 is connected by a water channel S5, and the water channel opening 16 and the inflow port 15 are connected by a water channel S6. In this state, 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 S5, the water channel 17 and the outflow connection pipe 22, and the filter 20b, that is, the pores of the hollow fiber membrane.

That is, the tap water is made to flow in the reverse direction to the case where ionic water is generated in the hollow fiber membrane in the water purifier 20, whereby the dirt attached to the pores of the hollow fiber membrane is removed and washed, and the filter 20b is washed. Is done.

Next, the operation panel 84 shown in FIG. 6 will be described. On the operation panel 84, a switching knob 85 and a switching knob 85 for switching between "power OFF (purified water)", "medical (ion water)" and "cooking" operation modes are selected from "power OFF (purified water)". When switched to "medical (ion water)" and "cooking", the indicator lamp 86 corresponding to the display of "in production", which indicates that the ion water is being produced, displays the amount of calcium adhering to the electrodes. An indicator lamp 87 corresponding to a "cleaning" display indicating that the electrode cleaning operation for removal is in progress, and the ionic water generated in the second tank 55 is alkaline ionic water or acidic ionic water. "Mode switch" switch button 88 for switching between the two and display lamps 88a and 88b corresponding to the display of "alkali" and "acidic", and the pH value of the ion water generated in the second tank 55 is adjusted. Shows the stage of "pH stage" changeover switch button 89 and pH value "strong",
Indicator lamps 89a, 8 corresponding to the display of "medium" and "weak"
9b and 89c, a display lamp 90 corresponding to the display of "cartridge replacement" indicating that it is time to replace the water purifier 20 is provided.

Then, the switching knob 85 is set to "power off.
Since the electrolytic ion water generator 1 is not connected to the power source when it is switched to (purified water), the solenoid valve 4
0 is closed and the solenoid valve 44 is open. The solenoid valves 48 and 49 are also closed. In this state, the switching lever 10b of the switching device 10 is used to move the switching device 10
2 is formed, the tap water from the faucet 3 to the water passage S1, the water pipe 61, the constant flow valve 42,
Filter device 30, flow sensor 43, inflow pipe 63,
Solenoid valve 40, bypass water pipe 65, water pipe 72, water passage S
2. It flows out from the water injection port 13 through the water purifier 20 and the water channel S3.

When the switching knob 85 is switched to "medical (ionized water)", the solenoid valve 44 is opened and the solenoid valves 40, 48 and 49 are closed by the control means (not shown). At this time, if the pH value is adjusted to "weak" by operating the "pH step" changeover switch button 89 for adjusting the pH value, the solenoid valve 46 is closed. Ion water is water pipe 6
The water is drained from the drain port 19 via the bypass drain pipe 70a and the bypass drain pipe 70a. Further, when the pH value is selected as “strong”, the valve opening amount of the solenoid valve 49 is large, and when the pH value is selected as “medium”, the valve opening amount of the solenoid valve 49 is opened accordingly. It is considered as the quantity. When the solenoid valve 46 is opened, the ion water from the first tank 54 is drained through both the solenoid valve 46 and the bypass drain pipe 70a.

When the switching knob 85 is switched to "for cooking", tap water from the inflow pipe 64 is directly flown to the inflow pipe 66 without passing through the calcium addition container 35 by a switching valve (not shown). Thus, the switching valve (not shown) is switched so as to generate ionized water. This is done in order to save consumption of the calcium content of the calcium additive 33 because whether or not the calcium content is added to the ionized water used for cooking does not affect the taste of the cooked food. is there.

Further, the flow rate sensor 43 has a function of integrating the flow rate of tap water flowing through it, and when the integrated flow rate reaches a predetermined value, the control means (not shown) is When the tap water is stopped, the polarities of the electrodes 51 and 52 are reversed and the electromagnetic valve 48 and the electromagnetic valve The valve 49 is kept for a predetermined time, that is, the cleaning water for the electrode in the electrolytic cell 50 is supplied with an inflow pipe 67, a drain pipe 68, a solenoid valve 48, and a solenoid valve 4.
9. The solenoid valve 48 and the solenoid valve 49 are controlled so that the solenoid valve 48 and the solenoid valve 49 are opened and closed for the time required for draining from the drain port 19 via the drain pipe 75. When the cleaning operation is being performed, the display lamp 87 corresponding to the above-mentioned "during cleaning" is displayed.
Is lit up.

When the flow rate accumulated by the flow rate sensor 43 reaches the flow rate corresponding to the replacement time of the filter 20b, the control means (not shown) indicates that the filter 20b in the water purifier 20 is the replacement time. The display lamp 90 corresponding to the display of "cartridge exchange" is turned on to notify.

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

In this case, first, the switching knob 85 is switched to the "medical (ionized water)" position as described above. In response to the switching to this position, the control lamp (not shown) turns on the display lamp 86 corresponding to the display of "generating", the solenoid valve 44 is opened, and the solenoid valve 40 is closed. That is, the solenoid valve 40 and the solenoid valve 44, which constitute the water channel switching means, work together to connect the inflow pipe 63 to the electrolytic cell 50 via the inflow pipes 64, 66, 67 and the like. Further, the solenoid valves 48 and 49 are closed. Next, the switching lever 10b is operated to switch the switching device 10 to the ion water production display position (not shown). In this state, as described above, the water channel structure of the switch 10 is the structure shown in FIG. When the "mode change" switch button 88 is operated and alkaline ionized water is desired, the "alkaline" mode is selected. Then, when the "pH step" button 89 for adjusting the pH value is operated, for example, when ionic water having a low pH value is desired, is set to "weak". At this time, the display lamp 89c lights up. When the faucet 2 is opened in this state, the tap water is
Water is sent to the filter device 30 through the intake 11, the water passage S1, the water supply port 14, and the inflow pipe 61, where chlorine, mold odor, organic matter, etc. are removed by the activated carbon 32, and then the flow rate sensor 43 and the inflow pipes 63, 64. , Flows into the calcium addition container 35 via the solenoid valve 44, and when passing through the calcium addition container 35, the calcium component is added. Then, it splits into the inflow pipes 67a and 67b through the inflow pipes 66 and 67, and flows into the first bath 54 and the second bath 55 via the intake ports 54b and 55b of the electrolytic bath 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, ionized water is generated in the first tank 54 as acidic ionized water, and ionized water in the second tank 55 as alkaline ionized water. Then, since the electromagnetic valve 46 is closed, the ion water generated in the first tank 54 is drained to the outside from the drain port 19 via the drain pipe 69, the electromagnetic valve 46, the bypass water distribution pipe 70a and the drain pipe 70. .
At this time, the amount of deionized water drained through the bypass drainage pipe 70a is small and electrolysis is suppressed.
The pH value of the ion water generated in the second tank 55 is a low value, that is, "weak".

The ion water generated in the second tank 55 flows into the inflow port 15, the water passage S2, the water passage port 16 and the like of the switch 10 through the water pipe 71, the check valve 47 and the water pipe 72. Water is sent into the water purifier 20 through the connecting pipe 21, and this ion water is stored in the water purifier 20 through the filter 20.
b, the outflow connection pipe 22, the waterway port 17, and the waterway S
After that, the water flows out of the water injection port 13 and is injected into a container or the like (not shown). When the ionized water passes through the filter 20b, E. coli or other miscellaneous bacteria present in the ionized water are removed by the filter 20b and purified.

When ionic water having a high pH value is desired, the "pH step" changeover switch button 89 is operated to select "strong". In this case, since the solenoid valve 46 is opened by the control means (not shown), the amount of ionized water drained from the first tank 54 increases, electrolysis is promoted, and the pH of the ionized water generated in the second tank 55 is increased. The value becomes a high value, that is, "strong", and when the pH value is desired to be medium, the "pH step" changeover switch button 89 is operated to "medium".
Select Then, the opening amount is controlled so that the amount of ionized water drained from the solenoid valve 46 is smaller than that in the case of “strong”, and the pH value of the ionized water generated in the second tank 54 is medium. The value is "medium".

In the above case, the case where the alkaline ionized water is desired has been described. On the contrary, when the acidic ionized water is desired, the "mode change" switch button 8 is used.
8 operations and switch to "acidic". When switched to “acidic”, the electrodes 51 and 52 are controlled by the control means.
Are switched so that the polarities thereof are reversed, and acidic ionized water is generated in the second tank 55, and the acidic ionized water is injected from the water injection port 13 of the switcher 10.

Next, a case will be described in which tap water is purified by removing E. coli and other germs without producing ionized water. In this case, the switching knob 85 is switched to the "power OFF (clean water)" position. In this state, as described above, the electrolytic ion water generator 1 is not connected to the power source, so the electromagnetic valve 40 is opened and the electromagnetic valve 44 is closed. The solenoid valves 48 and 49 are also closed. That is, the solenoid valve 40 and the solenoid valve 44 that constitute the water channel switching means cooperate with each other to bypass the electrolytic cell 50 and directly connect the inflow pipe 63 and the water supply pipe 72 via the bypass water supply pipe 65.

When the switching lever 10b of the switch 10 is switched to the water purification position (not shown), the water channel of the switch 10 has the water channel configuration shown in FIGS. When the faucet 2 is opened in this state, tap water flows from the faucet 3 into the intake 11, the water passage S.
1, the water supply port 14, the water supply pipe 61, and the filter device 30.
Chlorine, odor, etc. are removed by activated carbon 36, and then flow rate sensor 43, inflow pipe 63, bypass water supply pipe 65 and solenoid valve 40, check valve 41, water supply pipe 72, and water passage S2. The water is sent into the water purifier 20, the Escherichia coli and other miscellaneous bacteria are removed by the filter 20b in the water purifier 20, and the water is purified, and then the water is injected from the water injection port 13 into a container or the like not shown through the water passage S3. When tap water is purified by the water purifier 20 as described above, the tap water does not flow into the electrolysis tank 50. Therefore, since the length of the water channel during purifying can be shortened, the tap 2 must be opened before purifying water. It can be obtained in a short time without taking time to obtain it. Further, it is impossible that tap water does not remain in the electrolytic cell 50 and water can be saved and various bacteria do not propagate in the residual water.

Next, the filter 20 of the water purifier 20
b, that is, the case of cleaning the hollow fiber membrane will be described.
In this case, the switching lever 10b is switched to a cleaning display position (not shown), and the water channel structure of the switching device 10 is set to the structure shown in FIG. When the filter washing switch (not shown) is closed, the solenoid valve 49 is opened and the solenoid valve 48 is closed by the operation control means. Then, when the faucet 2 is opened, tap water is supplied to the intake 11, the water channel S5, and the water channel 1
7 and the outflow connecting pipe 22 to flow into the water purifier 20, and then flow through the filter 20b, that is, the pores of the hollow fiber membrane, in the direction opposite to the above-mentioned ion water generation, and the inflow connecting pipe 2
1, it flows through the water supply pipe 72 through the water passage port 16 and the water passage S6, and then is discharged to the outside through the drainage pipe 74, the solenoid valve 49, and the drainage pipe 75 as shown in FIG. And
The hollow fiber membrane is washed from the opposite direction with tap water, and the contaminants adhering to the pores of the hollow fiber membrane are removed with a water stream to clean the filter 20b.

When tap water is used as it is,
By operating the switching lever 10b as described above, the tap water can be directly discharged from the faucet 12 of the switching device 10 by forming the water passage configuration in which the intake 11 and the faucet 12 are connected to each other by the water passage S4 as shown in FIG. Is something that can be done.

If a large amount of ionized water is produced for a long period of time, calcium components adhere to the electrodes 51 and 52 in the electrolytic cell 50 to lower the electrolysis capacity. This is due to the integration of the flow rate sensor 43. When the flow rate reaches a predetermined value, it is automatically washed under the control of the control means as described above.

As described above, the electrolytic ion water generator 1
When tap water is to be purified and used without generating ionized water, the faucet 3 of the tap 2 of the tap, which is the water supply unit, is used.
Since the inflow pipe 63 for flowing the tap water from is connected directly to the water supply pipe 72 connected to the water purifier 20 by bypassing the electrolysis tank 50, the water passage at the time of water purification can be shortened. And the electrolytic cell 50
Since tap water does not remain inside, it is possible to improve water purification efficiency, and since tap water does not remain inside the electrolysis tank 50, various bacteria propagate in the residual water unlike the conventional case. Can be eliminated.

In the above embodiment, activated carbon 33
The filter device 30 and the calcium addition container 35 storing the above are provided separately from the water purifier 20. This is because the activated carbon 33 and the additive 36 for adding calcium are stored together in the water purifier 20. Alternatively, the filter device 30 and the calcium addition container 35 may be omitted.

Further, in the above embodiment, the water channel switching means is constituted by the solenoid valve 40 and the solenoid valve 44. This is, for example, as shown in FIG. With a solenoid valve 40a having outlets R1 and R2,
The inflow pipe 63 is connected to the inflow port I, the inflow pipe 64 is connected to one discharge port R1, and the bypass water supply pipe 65 is connected to the other discharge port R2.
As shown in FIG. 7 (B), the inflow port Q and the discharge port R1 are communicated with each other by a water channel S11, and as shown in FIG. 7 (C), the inflow port Q and the discharge port R2 are communicated with each other by a water channel S12. As described above, the switching may be selectively performed, and in this case, only one solenoid valve may be used as the switching means.

Further, in the above embodiment, the solenoid valve 4 when not energized is used.
Although 0 is opened and the solenoid valve 44 is closed, this may be reversed. In this case, which one should be selected may be determined depending on which of ion water and purified water is mainly produced. In other words, power can be saved by deciding whichever has the longer usage time. In addition, since it is possible that the usage time of the ionized water and the purified water generation will be reversed while using it for a long time, that is, the usage mode may be reversed, a switching means that can be selected to either is provided, and depending on the usage mode. The opening / closing of the electromagnetic valves 40 and 44 may be changed.

The inflow pipe 63 and the inflow pipe 64 constitute an inflow pipe communicating with the intakes 54b and 55b of the electrolytic cell 50, and the purified water supply pipe 265 is branched from the inflow pipe thus configured. It is what has been.

An electromagnetic valve 40 and a check valve 41 are connected to the purified water supply pipe 265. This solenoid valve 40
And the solenoid valve 44 switches the inflow pipe 63 to the inflow pipe 64 and the purified water supply pipe 265, that is, constitutes a water passage switching means for switching the water passage between the inflow pipe constituted by the inflow pipe 63 and the inflow pipe 64 and the purified water supply pipe 265. ing. The operation of the solenoid valves 40 and 44 as the water channel switching means is the same as that of the embodiment of the invention described in claim 1. The configuration other than the above is the same as that of the embodiment of the invention described in claim 1.

Next, the operation of the electrolytic ion water generator 200 will be described. First, the case of generating ionized water will be described.

In this case, the switch 210 is switched to the ion water production display position by operating the switch lever (not shown).
In this state, as described above, the structure of the water channel of the switch 210 is such that the intake port 211 and the water supply port 214 are the water channel W as shown in FIG.
1, and the water injection port 213 and the inflow port 215 are connected by the water passage W2. Then, the switching knob 85 is switched to the "medical (ionized water)" position. In this state, the solenoid valve 44 is controlled by a control means (not shown).
Opened and solenoid valve 40 closed. In addition, the solenoid valve 48,
The solenoid valve 49 is closed. Further, the "pH step" changeover switch button 89 is operated and selected so that the pH value of the ionized water becomes a desired value. When the faucet 2 is opened, tap water is supplied to the faucet 3, the intake 11, the water passage W1, and the water supply port 2.
14, water is supplied into the water purifier 220 via the water supply pipe 61,
Here, chlorine, musty odor, organic matter, etc. are removed by the activated carbon 221, and then Escherichia coli and other miscellaneous bacteria are removed by the filter 222 to purify water, and then the water supply pipe 62, the constant flow valve 43 inflow pipe 63, the inflow pipe 64, and the solenoid valve. After passing through 44, it flows into the calcium addition container 35 where the calcium component is added. Then the inflow pipes 66, 67 and 67a,
It flows into the first tank 54 and the second tank 55 of the electrolytic cell 50 from the intakes 54b and 55b via 67b.

The "mode switching" switch button 89 may be operated as desired to generate alkaline ionized water or acidic ionized water.

Next, a case where tap water is purified without producing ionized water will be described. In this case, the switching knob 85 is switched to the "power OFF (clean water)" position. In response to this switching, the control means opens the solenoid valve 40 and closes the solenoid valves 44, 48 and 49. Then, when the faucet 2 is opened in this state, tap water is supplied to the faucet 3, the intake 11, the water passage W1, and the water supply port 1.

Further, as described with reference to FIG. 7 as a modified example of the embodiment of the invention described in claim 1, one solenoid valve 40 and 44 are not used as the water channel switching means and one solenoid valve is used. It goes without saying that it may be configured with a valve.

Further, in the above embodiment, the water purifier 22
Although the 0 and the calcium addition container 35 are provided separately, this may have a finish so as to be integrally stored in the water purifier 220.
