However, at the time of electrolytic cleaning, the alkaline water outlet flow passage E is connected to the alkaline water extraction flow passage F through the fourth communication passage 63.
And, respectively, act as an electrode cleaning water outlet channel and an electrode cleaning water outlet channel.

On the other hand, when the rotary handle 62 is operated to rotate the flow path switching device shaft 61 by 90 ° clockwise in FIG. 1, the upstream side of the raw water supply flow path C connected to the tap water supply unit 1 and the raw water. Although the communication with the downstream side of the supply flow path C is blocked, the upstream side is connected with the raw water direct extraction flow path D through the third communication path 60.

(Switch and Indicator Lamp) As shown in FIG. 1, a pressure switch S ₁ is attached to the downstream side of the branch channel 24 of the raw water supply channel C and the alkaline water outlet channel E.
The pressure switch S ₁ is operated by the supply water pressure when the raw water is supplied from the raw water supply passage C to the electrolysis water purifier A through the water purifier 2, and a predetermined voltage is supplied from the power source 40 via the controller R to the electrode 8 , 9 to generate alkaline water in the alkaline water tank 12, and the acidic water tank 13
Acidic water can be generated within.

As described above, in the present embodiment, it is not necessary to separately provide a switch for operating the electrolyzed water conditioner A, and the control is simplified.

An operation panel OP is connected to the control unit R, and the power switch S ₂ is connected to the operation panel OP.
And the electrode cleaning switch S ₃ are attached.

Here, the power switch S ₂ is used for supplying electric power to the electrolytic water conditioner A and various switch groups.

On the other hand, the electrode cleaning switch S ₃ is connected to the controller R
A predetermined voltage is applied from the power source 40 to the electrodes 8 and 9 via
It is used for cleaning the electrodes to remove the deposits on both electrodes 8 _and 9.

Further, as shown in FIG. 1, in the display section of the control unit R, a power source display lamp L ₁ showing a state in which the power source 40 is turned on, and deposits on the electrodes 8 _and 9 are washed. The electrode-cleaning display lamp L ₂ as an electrode-cleaning display section that warns the user that it is necessary, and the electrode-cleaning display lamp L ₃ that indicates that the electrode cleaning work is in progress are installed. .

(Structure of Control Circuit R) FIG. 2 conceptually shows the control circuit R for the water conditioning work of the water conditioning system B including the above-mentioned electrolytic water conditioning apparatus A.

As shown, the control circuit R includes an input interface a, a microprocessing unit b,

The input interface a has a power switch S ₂ , a pressure switch S _1, and an electrode cleaning switch.
S ₃ is connected to the output interface c,
Power supply 40, calcium supply pump 3b, power supply indicator lamp
L ₁ , the electrode cleaning indicator lamp L ₂ and the electrode cleaning indicator lamp L ₃ are connected.

Further, in the present invention, the control circuit R is provided with the timer e, and the control circuit R is controlled by the timer e.
The following operation control is performed.

First, based on the control signal from the control circuit R, the cumulative time of electrolysis water conditioning performed by applying a forward voltage from the power source 40 to the electrodes 8 and 9 exceeds the set time (for example, 40 minutes). If, turns on the main electrode cleaning display lamp L _2, electrodes _8,
Notify the user that cleaning 9 is necessary.

When the user presses the electrode cleaning switch S ₃ when the electrode cleaning indicator lamp L ₂ lights up, the control circuit R
A reverse voltage is applied from the power supply 40 to the electrodes 8 and 9 based on the control signal from the device, and the set electrode cleaning time (for example, 2 minutes)
After the passage of time, a forward voltage is again applied from the power source 40 to the electrodes 8 and 9, and the normal operation of electrolysis water conditioning is restarted.

Immediately after the normal operation is resumed, the cleaning drainage and the electrolyzed water are mixed. Therefore, in order to prevent accidental ingestion of the mixed water, immediately after the restart, for example, for 10 seconds, the electrode cleaning indicator lamp is displayed. It is desirable to make some efforts such as continuing to display L ₃ (see Fig. 3 (f)).

When the tap water supply unit 1 such as a faucet is closed and the tap water supply unit 1 is opened again in a state where the set electrode cleaning time is not reached, the electrodes 8 _and 9 are sequentially operated.・ Reverse voltage is not applied, only the electroless water that has passed through the water purifier 2 is discharged, only the electrode cleaning display is required, and when the electrode cleaning switch S ₃ is activated during electrode cleaning, residual electrode cleaning is performed. Reverse voltage is applied to both electrodes 8 _and 9 for a certain period of time to perform electrode cleaning, and after the remaining electrode cleaning time has elapsed, electrolysis water preparation is restarted.

(Other Structure) Explaining the other structure in FIG. 1, reference numeral 42 is a safety valve provided in the middle of the raw water supply channel C, which is, for example, a switching valve using a shape memory alloy, and which is a tap water supply unit. When the water from 1 is hot water from a water heater, etc., when hot water of a certain temperature or higher is supplied, the function of the shape memory alloy prevents the water from flowing in the direction of the electrolytic water purifier A. It can be discharged to the outside through a hot water discharge passage (not shown).

(Operation of Electrolytic Water Conditioner A) Next, a method of using the electrolytic water conditioner A having the above configuration will be described with reference to the timing charts shown in FIGS. 1, 3 and 4.

(In case of normal manual electrode cleaning (FIG. 3)) First, during normal use, the water conditioning system B is in the state shown in FIG. 1, and the upstream side of the raw water supply channel C is a channel switching device. The first communication passage 58 and the second communication passage 59 in 41 communicate with the downstream side of the raw water supply flow passage C, while the alkaline water outlet flow passage E passes through the fourth communication passage 63 in the flow passage switching device 41 through an alkali. It communicates with the water extraction flow path F.

As shown in FIG. 3 (a), when the tap water supply unit 1 such as a faucet is opened after the power switch S ₂ is turned on, the raw water is electrolyzed from the tap water supply unit 1 through the raw water supply passage C. It will be supplied to the inflow side of the water conditioner A.

As shown in FIG. 3 (b), the pressure switch S ₁ is activated by the supplied water pressure, and the power is supplied via the control unit R.
While applying a predetermined forward voltage to the electrodes 8 and 9 from 40, the feed pump 3b is operated as shown in FIG.
Calcium is supplied to the acidic water tank 13 and electrolyzed to generate alkaline water in the alkaline water tank 12 and acidic water in the acidic water tank 13.

The generated alkaline water is supplied to the alkaline water outlet channel E → the third connecting channel 60 in the channel switching device 41 →
It can be discharged to the outside through the alkaline water extraction flow path F and can be used as drinking water (Fig. 3 (h)).

On the other hand, the acidic water produced in the electrolytic water purifier A can flow out to the outside through the acidic water outlet flow passage H, and the washing water for the hands etc. is used as the washing water by paying attention to the astringent effect. Can be used as

(In case of manual cleaning) Next, as shown in FIG. 3 (d), when the cumulative electrolytic water conditioning time calculated by the timer e in the control circuit R exceeds the set time (for example, 40 minutes). The electrode cleaning indicator lamp L ₂ lights up to inform the user that the electrodes 8 _and 9 need cleaning.

When the user presses the electrode cleaning switch S ₃ as shown in FIG. 3 (e) when the electrode cleaning indicator lamp L ₂ lights up, the control signal from the control circuit R causes
A reverse voltage is applied from the power supply 40 to the electrodes 8 and 9 (Fig. 3 (f)),
It is possible to dissolve and remove deposits attached to both electrodes 8 and 9. Then, the post-cleansing acidic water containing the dissolved and removed deposits can flow out to the outside through the alkaline water outlet channel E → the third connecting channel 60 in the channel switching device 41 → the alkaline water extracting channel F ( After washing, the alkaline water can be discharged to the outside through the acidic water outlet passage H (FIG. 3 (h)).

While the above-described electrolytic cleaning operation is continuing, the electrode cleaning indicator lamp L ₃ is turned on to inform the user of the fact (FIG. 3 (g)).

The electrode-cleaning display lamp L ₂ and the electrode-cleaning display lamp L ₃ described above are examples of display means.
Display means or warning means other than the lamp, such as a buzzer, may be used.

Furthermore, when water flow is stopped and water is restarted, if the set cleaning time has not expired, the electrodes are cleaned only for the remaining time, and electrolysis is performed after the set cleaning time has expired. Trying to start (Fig. 3 (c)
(f)).

(In the case of automatic cleaning (FIG. 4)) Next, automatic cleaning of the electrodes in the electrolytic water conditioner A having the above-described configuration will be described.

As described above, in normal use, as shown in FIG. 4 (d), when the cumulative electrolytic water conditioning time exceeds the set time (for example, 40 minutes), the electrode cleaning indicator lamp L ₂ lights up. Then, the user is informed that the electrodes 8 _and 9 need to be cleaned, and the lighting of the electrode cleaning indicator lamp L ₂ is detected.
As shown in, when the user presses the electrode cleaning switch S ₃ ,
Electrode cleaning is performed (Fig. 4 (f)).

However, if the user does not press the electrode cleaning switch S ₃ despite the fact that the electrode cleaning indicator lamp L ₂ is lit, the electrode cleaning will of course not be performed.

Therefore, in the present embodiment, the electrode cleaning is automatically performed as follows.

That is, the lighting time of the electrode-cleaning display lamp L ₂ is accumulated, and after the set cumulative time has elapsed, the cleaning operation is started immediately from that point, as shown in FIG. 4 (f).
The cleaning operation is started by the next actuation of the pressure switch S ₁ ,
Adhesives attached to both electrodes 8 and 9 are dissolved and removed.

At this time, however, the electrode cleaning indicator lamp L ₃
The user may drink even though is lit in Fig. 4 (g). In this case, the user will drink acidic water, which is a problem.

Therefore, in this embodiment, FIG. 4 (c) and FIG.
As shown in (f) and FIG. 4, in the electrode cleaning mode,
A forward voltage and a reverse voltage are alternately and repeatedly applied to the electrodes 8 and 9.

As a result, water obtained by mixing acidic water and alkaline water, that is, neutral water, is discharged from the alkaline water outlet channel E → the third connecting channel 60 in the channel switching device 41 → the alkaline water extracting channel. It will be possible to flow out through F.

There are various conceivable cycles of this alternating application, but in the longest case, it is sufficient that at least one cup of water is not biased to water of one polarity. You may apply.

Therefore, even if the user accidentally drinks it, the safety of the user can be sufficiently ensured.

In the cleaning by the alternating application, the time of the back cleaning is shorter than that in the manual cleaning, so that the time until the cleaning is completed is set longer than that in the manual cleaning. After cleaning is completed,
Return to normal state.

Even when the above-described automatic cleaning is in progress, as described with reference to FIG. 3, the electrode cleaning switch is used.
Manual electrode cleaning can be performed by pressing S ₃ .

The ratio of application of the reverse voltage and the forward voltage is not limited to 1: 1 as shown in FIG. Therefore, as shown in FIG. 6, even if the ratio of the reverse voltage and the forward voltage is 9: 1, the acidity is weakened by the forward voltage application as compared with the case where the reverse voltage is applied. So
Even if the user accidentally swallows it, it is possible to secure sufficient safety. By doing so, of course, the reduction in the cleaning effect of the electrodes 8 and 9 can be suppressed to a minimum, and an improvement in the cleaning effect can be expected in consideration of the above-mentioned spike-like inversion application.

(Embodiment 2) As shown in FIGS. 7 and 8, this embodiment is characterized in that the application of forward voltage and the application of reverse voltage are alternately repeated during the normal electrolysis operation. To do.

In this case, the electrode can be cleaned while the normal electrolysis operation is mainly performed.

Therefore, it is not necessary to provide the electrode cleaning operation (mode) in addition to the normal electrolysis operation (mode), and the user can save the trouble of cleaning.

In this case, sufficient alkaline water can be obtained if the ratio of the application time of the reverse voltage to the forward voltage is about 1: 9.

It should be noted that such an alternate application ratio can be provided in the main body by a variable mechanism. If the main body has a variable part, the pH value setting, which was conventionally controlled by the current value etc., can be adjusted by mixing alkali and acid.

(Embodiment 3) In Embodiment 2 described above, since the electrode cleaning mode is not provided, there is a possibility that the electrodes 8 and 9 of the electrolytic cell 10 cannot be cleaned in earnest.

Therefore, in this embodiment, the electrolytic water purifier A is used.

Further, reference numeral 91 is a contact provided on the inner surface of the protective casing 71, and reference numeral 92 is a drain hole for preventing the contact 91 from getting wet with water.

In such a structure, by only inserting the electrolysis tank 10 into the protective cylinder 71, the purified water inflow opening 73, the alkaline water outflow opening 74 and the acidic water outflow opening 75 provided at the bottom of the electrolysis tank 10 are Each of them can be connected to the purified water inflow opening connection port 81, the alkaline water outflow opening connection port 82, and the acidic water outflow opening connection port 83 in a watertight state.

At this time, the cylindrical portions of the purified water inflow opening 73 and the alkaline water outflow opening 74 push the valve bodies of the opening / closing valves 87, 89 downward, so that the purified water inflow opening 73 and the alkaline water outflow opening 74 are
Each of them communicates with the purified water inflow pipe 84 and the alkaline water outflow pipe 85. Further, the contact point 76 comes into contact with the contact point 92, and the electrolytic operation becomes possible.

On the other hand, at the time of replacement, when the electrolysis tank 10 is pulled up, the purified water inflow opening provided at the bottom of the electrolysis tank 10
73, the alkaline water outflow opening 74, and the acidic water outflow opening 75 are separated from the purified water inflow opening connection port 81, the alkaline water outflow opening connection port 82, and the acidic water outflow connection port 83, respectively.

At this time, since the pressing force of the cylindrical portions of the purified water inflow opening 73 and the alkaline water outflow opening 74 is released, the on-off valves 87, 89
Since the valve body of (1) rises to close the valve seat and the purified water from the purified water inflow pipe 84 communicates with the alkaline water outflow pipe 85, there is no risk of water overflowing even with the cartridge removed.

In the above embodiment, the electrolytic cell is used.
