DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to electrolysis of tap water and well water (hereinafter referred to as tap water) in an electrolytic cell to produce electrolytic ionic water and chlorine, E. coli, etc. contained in the tap water. The present invention relates to an electrolytic ion water generator of a type that can be used as a water purifier that removes various bacteria and purifies tap water.

[0002]

2. Description of the Related Art Conventionally, it has been used as an ion water generator that electrolyzes tap water to produce ion water, and also has a water purification function for purifying tap water by removing chlorine and various bacteria contained in tap water. An electrolytic ion water generator that can also be used as a water purifier is widely known. The configuration of this type of conventional electrolytic ionized water generator is generally as shown in FIG. That is, as shown in FIG. 3, the electrolytic ionized water generator 100 is connected to a water supply pipe 101 for feeding tap water which is connected to a tap of a tap (not shown), and chlorine, Escherichia coli and other various bacteria contained in tap water. A water purifying container 102 for removing water etc., a calcium adding container 104 connected to the water purifier 102 via a water pipe 103, and adding a calcium component to tap water purified in the water purifying container 102,
It is composed of an electrolytic cell 110 and the like connected to the calcium addition container 104 via a water supply pipe 105. And, the diaphragm 111 having water permeability in the electrolytic bath 110.
Is arranged, and is partitioned by the diaphragm 111 to separate the first tank 112.
And a second tank 113 are formed, and electrodes 114 and 115 are arranged in the first tank 112 and the second tank 113, respectively. The positive electrode and the negative electrode of the DC power supply device 116 are connected to the electrodes 114 and 115, respectively. Then, when the DC power supply device 116 supplies power to the electrodes 114 and 115 while injecting tap water into the electrolyzer 110, acidic ionized water (hereinafter referred to as acidic water) is supplied to the first tank 112, and inside the second tank 113. Alkaline ionized water (hereinafter referred to as alkaline water) is generated in each. Then, the acidic water is drained from the drain pipe 117, and the alkaline water is poured into a container or the like (not shown) via the water injection pipe 118. A constant flow valve 120 is connected to the water supply pipe 103 so that a constant flow of tap water flows into the electrolytic cell 110 even if the pressure of the tap water changes. Further, a pressure switch 121 is connected to the water supply pipe 103, and the operation of the pressure switch 121 causes the DC power supply device 116 to start feeding power to the electrodes 114 and 115. Further, a drain pipe 119 to which an electromagnetic valve 122 is connected is connected to the water supply pipe 105 connected to the electrolyzer 110.

Next, the operation of the electrolyzed ionized water generator 100 will be described. First, when alkaline water is generated by using it as an ionized water generator, tap water (not shown) is opened to feed tap water. 101, water purifier 102,
It flows into the electrolytic cell 110 through the water supply pipe 103, the calcium addition container 104, and the water supply pipe 105. When tap water flows into the water pipe 103, the pressure switch 121
Is operated, electricity is supplied to the electrodes 114 and 115 from the DC power supply device 116, and tap water is electrolyzed to generate acidic water in the first tank 112 and alkaline water in the second tank 113. Water is injected from a water injection pipe 118 into a container (not shown), and acid water is discharged through a drain pipe 117.

Next, when using as a water purifier, when the tap of the water supply is opened with the power supply from the DC power supply device 116 stopped, tap water passes through the water supply pipe 101 and the water purifier 1
02, and the hollow fiber membrane and the activated carbon housed inside the water purification container 102 remove chlorine, Escherichia coli and other germs and odors, and purify the water. Then, this purified water, that is, purified tap water, is the water pipe 10.
3, through the calcium addition container 104 and the water supply pipe 105, it flows into the electrolytic cell 110. Then, this purified water is poured into a container (not shown) through the water injection pipe 118 for drinking and a part of this purified water is the drain pipe 117.
The purified water drained from the drain pipe 117 is drained without being used for drinking, and the purified water is wasted wastefully, so that it is not possible to save water and the water use efficiency is not improved. Is a bad thing.

An electrolytic ionized water generator improved in this respect is disclosed in, for example, Japanese Patent Application Laid-Open No. 5-269467. One of them is the anode chamber and the cathode chamber of the electrolytic cell for electrolyzing the purified water purified by the water purifier as described in the above-mentioned page 5, left column, lines 12 to 45 and FIG. In addition to providing a water outlet in each, a solenoid valve is provided in the water outlet provided in the anode chamber, the solenoid valve is opened when generating alkaline water, and purified water without electrolysis in the electrolytic cell. When the water is taken out of the water discharge passage provided in the cathode chamber, the solenoid valve is closed to prevent the purified water from flowing out of the water discharge passage provided in the anode chamber, thereby saving water and increasing the water utilization rate. Is what you are doing.

However, in the above-mentioned structure, since the internal flow passage in the electrolytic cell is a narrow flow passage sandwiched between the anode and the cathode,
Large resistance to fluid, large pressure loss in the electrolytic cell,
In addition, since the water is discharged only from the water outlet of the anode chamber, there is a problem that the flow rate of the entire water system is reduced and the amount of water discharged per unit time is reduced.

A further improvement of this disadvantage is described in the same publication, page 5, right column, line 7 to page 6, left column, second line and FIG. This product has a conduit for introducing purified water purified by the water purifier to the electrolytic tank in the conduit provided downstream of the water purifier and a water conduit for directly guiding the alkaline water to the discharge port without guiding the electrolytic water to the electrolytic tank. When it is desired to take out only purified water that has been purified without generating alkaline water by providing flow path switching means for switching, the water channel switching means should connect the water conduit and the water conduit provided downstream of the water purifier. By switching to, the purified water purified by the water purifier is directly taken out from the discharge port.

This is because the purified water is not discharged, and the purified water purified by the water purifier does not pass through the electrolytic cell. It also has the advantage that the amount of purified water per unit does not decrease because it does not flow in the electrolytic cell having a large flow resistance.

However, this has the following drawbacks. One of them is that when the water supply is stopped after the production of the purified water is stopped, a part of the purified water remains in the water supply passage connecting the water passage switching means and a ball valve provided near the discharge port. This residual purified water is disadvantageous in terms of hygiene, because if it is opened until the next use, the residual purified water may be decomposed or bacteria may be propagated. . In particular, purified water is free from chlorine, which has a bactericidal action, and thus bacteria and the like are easily proliferated. In addition, the other one is that when the purified water is being taken out, the purified water does not flow through the electrolytic cell, so the electrolytic cell is empty, so When the switch is made to take out alkaline water, in addition to the electrolysis cell being empty, the flow path resistance in the electrolysis cell is large, and as a result, the purified water from the water purifier is placed in this electrolysis cell. This is a disadvantage that it is not preferable in terms of usability because it takes time to fill the flow-in electrolytic tank with purified water and it takes time to take out the alkaline water from the switching operation.

[0010]

As described above, when the conventional electrolytic ionized water generator is used as a water purifier, there is a problem that a part of the purified water is drained to the outside through the drain pipe to save water. In addition, in the case where a solenoid valve is installed in the drain pipe to prevent the purified water from draining from the drain pipe during water purification to save water, the flow path resistance in the electrolytic cell is large and pressure loss in the electrolytic cell is large. The flow rate of the entire system is greatly reduced,
There is a problem that the amount of water discharged per unit time decreases, and in the case where the purified water is guided directly to the discharge port without passing through the electrolytic cell via the water supply passage, a part of the purified water will enter the water supply passage. In addition to the fact that the residual purified water is not preferable from the viewpoint of hygiene, there is a risk that the residual purified water will rot or bacteria will propagate if the usage interval until the next time opens. Therefore, when the alkaline water is taken out from the state in which the purified water is taken out, it takes time from the switching operation to take out the alkaline water, which is not preferable in terms of usability.

[0011]

A pair of electrodes consisting of a positive electrode and a negative electrode arranged in the second tank, and a DC power supply device for supplying a current to the pair of electrodes are provided, and the drain valve is opened when electrolytic ion water is generated. In addition, the bypass valve is closed, and when the purified water is taken out without generating electrolytic ion water, the drain valve is closed and the bypass valve is opened.

According to the present invention configured as described above, when the electrolyzed water, that is, the purified tap water is taken out as purified water without electrolyzing in the electrolytic cell, the drain valve is closed to prevent the purified water from flowing out from the drain pipe. By blocking and opening the bypass valve and letting the purified water in the first tank flow out to the water injection pipe through the bypass pipe, it is possible to prevent a decrease in the outflow amount of purified water per unit, and the purified water always passes through the electrolytic cell. Therefore, when switching from the purified water generation state to the electrolytic ion water generation state, the time from the switching operation to the extraction of electrolytic ion water, that is, alkaline water can be shortened. In addition, it is possible to eliminate the residual purified water in the bypass pipe.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described with reference to FIGS.

As shown in FIG. 1, an electrolytic ion water generator 1
Is a water purifier 20 for removing chlorine, Escherichia coli and various other bacteria contained in water (hereinafter simply referred to as tap water) as electrolyzed water from tap water or well water, etc.
It is composed of a tap water purified at 0, that is, a calcium addition container 30 for adding a calcium component to purified water, an electrolytic tank 40 for electrolyzing the purified purified water to generate ionized water, and the like.

Then, a hollow fiber membrane (not shown) for removing various bacteria such as Escherichia coli and organic substances contained in tap water flowing into the water purifier 20 through the water pipe 11 connected to the tap of the water supply (not shown), and It contains activated carbon that removes odors such as chlorine and mold. Further, the calcium addition container 30 is connected to the water purifier 20 via the water supply pipe 12. Although not shown, a calcium additive containing a calcium component such as calcium glycerophosphate is stored in the calcium addition container 30, and purified tap water flowing in through the water pipe 12 passes through the calcium addition container 30. The calcium content is added when doing. The calcium addition container 30 is connected to the electrolytic cell 40 via the water pipe 13. A sensor 31 and a constant flow valve 32 located downstream of the sensor 31 are connected to the water supply pipe 13, and the sensor 31 detects that tap water has started flowing into the water supply pipe 13. On the basis of the detection signal of the sensor 31, the control means (not shown) controls the energization of the electrodes 44 and 45, which will be described later, and the opening / closing control of the bypass valve 62. Further, the constant flow valve 32 is for maintaining a constant amount of tap water flowing through the water pipe 13 regardless of the water pressure.

The water supply pipe 13 is composed of water supply pipes 13a and 1a.
3b, and these water supply pipes 13a and 13b are connected to a first tank 42 and a second tank 43 of an electrolytic tank 40 described later.

The portions of the water supply pipe 12 and the water supply pipe 13 on the downstream side of the constant flow valve 32 are connected by a water supply pipe 14 having a small diameter, and a part of the tap water purified by the water purifier 20 is calcium. Electrolyzer 4 directly without passing through the addition container 30
It is designed to send water within 0.

Next, in the electrolytic cell 40, there is provided a water-permeable membrane 41 formed by coating polyethylene on a polyester nonwoven fabric, for example.
1 is divided into 1 to form a first tank 42 and a second tank 43,
The electrodes 4 are provided in the first tank 42 and the second tank 43, respectively.
A pair of electrodes 4 and 45 is provided. Each of the pair of electrodes 44 and 45 has a DC power supply device 5
The positive electrode 51 and the negative electrode 52 of 0 are connected to each other.

A drain port 42a and an outflow port 43 are provided in the upper part of the first tank 42 and the upper part of the second tank 43, respectively.
a is provided. Drainage port 4 provided in the first tank 42
A drain pipe 15 is connected to 2a.
Is provided with a drain valve 60 which is a pressure valve that operates at a predetermined pressure. As shown in FIG. 2, the drain valve 60 includes a housing 61 having a valve body storage chamber 61c having an inlet 61a at one end and an outlet 61b at the other end, and the valve storage chamber 6 described above.
1c is composed of a valve body 61d that is movably arranged and an elastic member 61e that normally urges the valve body to close the inlet 61a. The elastic member 61e is provided in the inlet 61a. When the water pressure of tap water, which is the fluid flowing in from the tank, is a predetermined pressure, that is, normal tap water pressure is applied, the inlet 6
It is set to a biasing force that opens 1a. That is, the magnitude of the urging force of the elastic member 61e is determined by the bypass valve 62 described later.
Tap water flows into the electrolytic cell 40 with the cell closed and the electrolytic cell 4
It is set to a value at which the inflow port 61a opens when the pressure of tap water that continues to flow in a state of satisfying 0 is applied to the valve body 61d.

A water injection pipe 16 having a discharge port 16a at its tip is connected to the outlet provided at the upper part of the second tank 43.

The drain pipe 15 and the water injection pipe 16 are connected by a bypass pipe 17.
A bypass valve 62 composed of a solenoid valve is connected to the.
The connection part between the bypass pipe 17 and the drain pipe 15 is a part upstream of the waste water valve 60 and in the vicinity of the drain port 42a, and the connection part with the water injection pipe 16 is the outlet port 4.
3a, and therefore, this bypass pipe 1
Since the total length of 7 is extremely short, and the connecting portions at both ends are near the drainage port 42a and the outflow port 43a respectively, purified water does not remain in the bypass pipe 17 including the bypass valve 62. is there. Bypass pipe 1
When 7 is configured to be connected to the drain pipe 15 and the water injection pipe 16 by inclining both end sides downward with the bypass valve 62 as the midpoint, the residual water in the bypass pipe 17 is removed from the first tank 42 and the The water can be poured into the two tanks 43, and it is possible to more reliably prevent the purified water from remaining in the bypass pipe 17.

The bypass valve 62 is used in the electrolytic cell 40.
It is in a closed state when electrolyzing purified water, that is, purified tap water to generate electrolytic ionized water, and is in an open state when tap water is not electrolyzed in the electrolytic cell 40, that is, when it is taken out as purified water. As described above, it is controlled by the control means. Further, when the electrolytic ion water is generated, the drain valve 60 is opened because the water pressure of tap water is applied to the valve body 61d because the bypass valve 62 is closed, and the electrolytic ion water in the first tank 42 is released. The bypass valve 6 is used when the purified water that has been discharged through the drain pipe 15 and that has been purified without producing electrolytic ion water is taken out as it is.
Since No. 2 is opened, the tap water in the first tank 42 is sent to the water injection pipe 16 through the bypass pipe 17, and the pressure of the tap water applied to the valve body 61d at this time does not reach a predetermined pressure. That is, the tap water in the first tank 42 is never discharged through the drain pipe 15.

Further, inlets 42b and 43b are provided at the bottom of the first tank 42 and the bottom of the second tank 43, respectively, and the water supply pipes 13a and 13b are connected to the inlets 42b and 43b. , This water pipe 13
Tap water is delivered via a and 13b. Further, one end of a drain pipe 18 is connected to the water supply pipe 13b, and the other end of the drain pipe 18 is connected to a downstream side portion of the drain pipe 15 and remains in the electrolytic cell 40 after use. Water can be discharged through the drain pipe 15. Further, the drain pipe 18 is connected to a drain valve 63 composed of a pressure valve configured in the same manner as the drain valve 60,
By opening the drain valve 63, the residual water in the electrolytic cell 40 is discharged. In other words, tap water is electrolyzer 4
When the water flows into 0, the tap water pressure closes the drain valve 63 to prevent tap water from flowing out of the electrolyzer 40, and when the tap water supply is stopped, the water pressure applied to the drain valve 63 is less than a predetermined pressure. Therefore, the drain valve 63 is opened, and the residual water remaining in the electrolytic cell 40 is discharged through the drain pipe 18 and the drain pipe 15.

Then, when tap current is supplied into the electrolytic cell 40 and a current is supplied from the DC power supply device 50 to the electrodes 44 and 45, acidic ionized water (hereinafter referred to as acidic water) is further supplied to the first tank 42. Alkaline ionized water (hereinafter referred to as alkaline water) is generated in the second tank 43. Then, the acidic water is discharged from the drain pipe 15, and the alkaline water is poured into a container or the like (not shown) through the discharge port 16a of the water injection pipe 16 for drinking.

Next, the operation of the electrolytic ionized water generator 1 will be described. First, when used as an ionized water generator to generate alkaline water, an operation button on an operation panel (not shown) is operated to set the electrolytic ionized water generation mode. Then, when a tap (not shown) of the water supply is opened, the tap water flows into the water purifier 20 through the water pipe 11, and the hollow fiber membrane and the activated carbon contained in the water purifier 20 remove various germs and chlorine. Water pipe 1 after odors such as mold have been removed
Water is sent to the calcium addition container 30 via 2. Then, when the tap water flows into the water supply pipe 13, this inflow is detected by the sensor 31, and this detection signal is sent to the control means (not shown), and the control means controls the DC power supply device 50 and the electrodes 44 and When the energization of 45 is started, the bypass valve 62 is controlled to be in the closed state.

The tap water, that is, the purified water in which the calcium content is added in the calcium addition container 30 is the water pipe 1.
Water is fed into the electrolysis tank 40 via 3a and 13b, electrolysis is performed in the electrolysis tank 40, and acidic water is generated in the first tank 42. The acidic water has the bypass valve 62 closed. Inflow to the bypass pipe 17 is blocked, and waste water is drained through the drain valve 60 and the drain pipe 15 which are in an open state. Further, the alkaline water generated in the second tank 43 is poured into a container or the like (not shown) from the discharge port 16a via the water injection pipe 16. In this state, since the drain valve 63 is closed, the tap water in the electrolytic cell 40 will not flow out from the drain pipe 18.

When the production of electrolytic ion water is completed and the supply of tap water is stopped, the drain valve 63 is opened, and the residual water remaining in the electrolytic cell 40 passes through the drain pipe 18 and the drain pipe 15. It is the wastewater.

Next, when using as a water purifier, an operation button of an operation panel (not shown) is operated to set the water purification mode so as to take out the water. In this mode, the power supply from the DC power supply device 50 to the electrodes 44 and 45 is stopped, and the bus pass valve 62 is opened.
Then, when the tap of the tap water (not shown) is opened, tap water is sent to the water pipe 11.
It flows into the water purifier 20 through the water, and the hollow fiber membrane and the activated carbon housed inside the water purifier 20 remove various bacteria and odors such as chlorine and mold to purify and produce purified water. After that, water is supplied to the calcium addition container 30 via the water supply pipe 12.

The tap water, ie, purified water, to which calcium has been added in the calcium addition container 30 is the water pipe 1.
The purified water that has been fed into the electrolysis tank 40 via 3a and 13b and has flowed into the first tank 42 is fed to the water injection pipe 16 through the bypass pipe 17 because the bypass valve 62 is open. Further, at this time, since the water pressure applied to the drain valve 60 is less than the predetermined pressure, it is in the closed state, so that the purified water in the first tank 42 is not discharged through the drain pipe 15. Therefore, all the purified water in the first tank 42 is discharged through the bypass pipe 17, the water injection pipe 16 and the discharge port 16.
As a result, the purified water will not be wasted. Further, the purified water that has flowed into the second tank 43 flows out from the discharge port 16 a via the water injection pipe 16. That is, in the water purification mode, the tap water purified by the water purifier 20, that is, the purified water, is the first tank 42 and the second tank 4 of the electrolytic tank 40.
The purified water that has flowed into the first tank 42 and the second tank 43 after flowing into the third tank 3 passes through the drain port 42a of the first tank 42 and the bypass pipe 17 and the outlet 43 of the second tank 43, respectively.
It is possible to flow into the water injection pipe 16 via a and to take out all of it from the discharge port 16a, so that the utilization efficiency of tap water can be improved.

In the purified water mode, when the purified water is taken out, as in the case of producing electrolytic ionized water, the first tank 4 is used.
Since it can be taken out from both the drainage port 42a provided in 2 and the outflow port 43a provided in the second tank 43, the flow rate when taking out purified water is the same as the flow rate when producing electrolytic ion water, Therefore, the flow rate per unit when taking out purified water does not decrease.

Further, even when the purified water is taken out, the electrolytic tank 40 is filled with purified water, that is, tap water. Therefore, when the electrolytic ion water production mode is switched to during use in the purified water mode, the tap water in the electrolytic tank 40 is immediately changed. As a result, the time from switching to the electrolytic ion water generation mode until taking out the alkaline water can be greatly shortened.

After the removal of the purified water in the purified water mode, tap water does not remain in the bypass pipe 17 even if the use interval is increased until the next use. The remaining residual water will not be spoiled, nor will it become unsanitary due to the propagation of various bacteria.

When the removal of purified water is completed and the supply of tap water is stopped, the drain valve 63 is opened and the electrolytic cell 40 is opened.
Residual water remaining inside is drain pipe 18 and drain pipe 15.
The wastewater is discharged through.

Further, since the drain valve 60 and the drain valve 63 are pressure valves which operate at a predetermined pressure, it is not necessary to control them by the control means, and the structure can be simplified and the cost can be reduced. It is a thing.
Needless to say, the drain valve 60 and the drain valve 63 may be electromagnetic valves or the like instead of pressure valves.

In the above embodiment, one end of the bypass pipe 17 is connected to the water injection pipe 16 near the outflow port 43a of the second tank 43, and the other end is connected to the drain pipe 15 to open and close the valve 60. Although it is configured to be connected upstream of and in the vicinity of the drain port 42a of the first tank 42, the other end side may be directly connected to the upper portion of the first tank.

[0036]

According to the present invention configured as described above, when the electrolyzed water, that is, the tap water purified by the water purifier is taken out as purified water without electrolyzing in the electrolytic cell, the drain valve is closed to remove the water from the drain pipe. By blocking the outflow of purified water and opening the bypass valve and letting out the purified water in the first tank to the water injection pipe through the bypass pipe, it is possible to prevent a decrease in the outflow amount of purified water per unit and improve the efficiency of tap water utilization. In addition, since the purified water always passes through the electrolysis tank, when switching from the purified water generation state, that is, the purified water generation mode to the electrolytic ion water generation state, that is, the electrolytic ion water generation mode, the electrolysis is performed from the switching operation. This has the effect of shortening the time required to take out ionized water, that is, alkaline water. In addition, since it is possible to eliminate the residual purified water in the bypass pipe, there is a risk that the purified water remaining in the water supply passage that was provided so as not to pass through the electrolytic cell during purification as in the past may be decomposed or that germs may be propagated. It can be resolved.
