Have to be able to.

In FIG. 1, reference numeral 90 denotes a flow control valve.

As shown in FIG. 10, the control circuit R has an input interface a, a microprocessing unit b, an output interface c, a memory d, and a timer e.

In principle, the splittable casing 70 is mounted on the rear casing 70b, while the calcium solution tank
With the exception of 3a, the electrical components such as the control circuit R and transformer 91 that dislike water are mounted on the front casing 70a. Therefore, even in the event of a water leak, the operation of the electrolyzed water dispenser A can be maintained, and a leakage accident or the like can be prevented as much as possible.

Further, in the assembled state of the casing 70,
The water circling components and the electric circling components are concentrated on the right side and the left side of FIG. 2, respectively.

Further, in FIG. 7, reference numeral 92 denotes a detachable cap for the water purifier 2.

(Operation of Electrolytic Water Purifier A) Next, a method of using the electrolytic water purifier A having the above configuration will be described with reference to timing charts shown in FIGS.

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 flow path C is provided with the first communication path 58 and the second communication path 59 in the flow path switching device 41. The alkaline water outlet channel E communicates with the alkaline water outlet channel F through a fourth communication channel 63 in the channel switching device 41.

[0060] As shown in FIG. 11 (a), after the power switch S ₂ is turned to open the tap water supply unit 1 of the faucet or the like, the raw water through the raw water supply passage C from tap water supply unit 1 is electrolyzed The water is supplied to the inflow side of the water conditioner A.

[0061] As shown in FIG. 11 (b), the pressure switch S ₁ is activated by the supply water pressure, power supply via the control device R
From 40, a predetermined forward voltage is applied to the electrodes 8, 9, and the feed pump 3b is operated as shown in FIG.
Calcium is supplied to the acidic water tank 13 and, by electrolysis,
An alkaline water is generated in the alkaline water tank 12, and an acidic water is generated in the acidic water tank 13.

The generated alkaline water is supplied to the alkaline water outlet channel E → the third communication channel 60 in the channel switching device 41 →
It can flow out to the outside through the alkaline water discharge channel F and can be used as drinking water (FIG. 11 (h)).

On the other hand, the acidic water generated in the electrolytic water purifier A can flow out to the outside through the acidic water outflow channel H. Can be used as

Next, as shown in FIG.
Cumulative electrolytic water conditioner time setting time timer e has been calculated by the in (e.g., 40 minutes) exceeds, main electrode cleaning display lamp L ₂ is lit, the electrodes _8, 9 user of that cleaning is required Tell

[0065] built into the lighting of the main electrode cleaning display lamp L _2, as shown in FIG. 11 (e), when the user presses the electrode cleaning switch S _3, based on the control signal from the control device R,
A reverse voltage is applied to the electrodes 8, 9 from the power supply 40 (FIG. 11 (f)),
Deposits adhering to both electrodes 8, 9 can be dissolved and removed. The washed acidic water containing the dissolved and removed deposits can flow out to the outside through the alkaline water outlet channel E → the third communication channel 60 in the channel switching device 41 → the alkaline water outlet channel F ( In FIG. 11 (h)), after washing, the alkaline water can flow out through the acidic water outlet channel H.

[0066] Incidentally, while the electrolytic cleaning operation described above is continued, that effect to inform the user, the display in the electrode flushing ramp L ₃ is turned on (FIG. 11 (g)).

[0067] Incidentally, a main electrode cleaning display and the lamp L ₂ and the electrode cleaning indicator lamp L ₃ is an example of a display means,
Display means or warning means other than lamps, such as a buzzer, can also be used.

By the way, if the water supply is continued during the set washing time, the forward voltage is applied again to the electrodes 8 and 9 from the power source 40, and the normal operation of electrolyzed water is restarted. For some reason, for example, the user may close the tap water supply unit 1 such as a faucet without being inconvenienced during electrode cleaning. In this case, as shown in FIG. 11 (b), the pressure switch S ₁ is turned off.

Thereafter, the user operates the tap water supply unit 1 such as a faucet.
Again when the open, as shown in FIG. 11 (b), the pressure switch S ₁ is turned on, then only the remaining electrode cleaning time, perform an electrode cleaning reverse voltages applied to the electrodes _8, 9 at the same time, The electrodes 8, 9 can be completely cleaned (FIG. 11 (f)).

After the elapse of the remaining electrode cleaning time,
FIG. 11 shows that neither forward nor reverse voltage was applied to both electrodes 8 _and 9.
As shown in (f), the electrode washing (reverse electrolysis) is not performed, and only the purified water can be safely drained from the alkaline water extraction flow path F (FIG. 11 (h)).

The reason for this is that the water immediately after the electrolytic cleaning is considered to be a mixture of the cleaning waste water and the alkaline water purified water.

[0072] Having described the water conditioner operation by electrolysis water conditioner A of the present invention, as shown by a chain line in FIG. 11 (c), at the same time when the main electrode cleaning display lamp L ₂ turned electrical The application of the voltage to the disintegrating water purifier A is stopped, and the electroless water is discharged, so that the deterioration of the electrodes 8 _and 9 can be prevented from progressing.

[0073]
