[Prior art]

 Conventionally, ion water purifiers and the like configured to electrolyze tap water or the like to generate and separate alkaline water and acidic water have been used.

This is because tap water or the like is once purified with activated carbon or the like and then fed to a reaction tank, and is applied between both electrodes by a diaphragm interposed between the cathode electrode and the anode electrode in the reaction tank. When tap water is electrolyzed by the generated voltage, it is configured to separate into alkaline water and acidic water, and the generated alkaline water and acidic water are separated into an alkaline water outlet channel and an acidic water outlet channel, respectively. It is made available to the outside through the company and can be used according to each application.

Further, since the calcium concentration of ionized water can be improved by adding a trace amount of calcium salt water, for example, as described in Japanese Utility Model Laid-Open No. 62-132800, a pump from a calcium solution tank is used. Has been developed to supply water containing calcium salt to the inside of the reaction tank.

The tank storage portion 71 includes a wide front wall 71a, left and right side walls 72 and 73, upper and lower walls 74 and 75, and a rear wall 76, and is used to store the calcium solution tank 3a therein. The tank storage space Y is formed.

A tubular pipe mounting portion 77 is formed on the upper portion of the back wall 76 of the tank storage portion 71, and is formed at the base end of the calcium supply pipe 3c through the pipe mounting portion 77. An in-tank insertion portion 79 with a flange 78 is inserted, and a calcium solution injection hole 80 is provided in the radial direction at the tip of the in-tank insertion portion 79.

The calcium solution injection hole 80 is preferably opened upward so as to prevent the solution from naturally dripping when the calcium solution tank 3a is detached.

On the other hand, the calcium solution tank 3a accommodated in the tank accommodating portion 71 is formed of a container body 81 having an upper end opening and a lid body 82 which covers the upper portion of the container body 81 in a watertight state. .

The calcium solution outflow cylinder 83 has a rear end opened, and a calcium solution suction cylinder 84 is provided in the semi-radial direction at the bottom of the front end thereof. The suction cylinder 84 is made of a flexible material such as silicone rubber. The upper end of the calcium solution suction throat 85 is attached, and the lower end of the throat 85 extends to the lower part inside the container body 81 and is inserted.

On the other hand, the in-tank insertion portion 79 of the calcium supply pipe 3c is inserted in the calcium solution outflow tube 83, and the calcium solution injection hole 80 provided at the tip of the tank insertion portion 79 and the calcium solution outflow are provided.

Other configurations in this embodiment will be briefly described below.

In FIG. 1, 42 is a safety valve provided in the middle of the raw water supply flow path C, which is, for example, a switching valve using a shape memory alloy, and water from the tap water supply unit 1 is supplied from a water heater or the like. In the case of hot water, when hot water of a certain temperature or higher is supplied, the function of the shape memory alloy prevents it from flowing in the direction of the electrolytic water conditioner A through a hot water discharge passage (not shown). It can be released to the outside.

Further, in FIG. 1, 90 is a flow rate adjusting valve.

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

Further, as shown in FIG. 7, the water purifier 2, the supply pump 3b, the reaction tank 10, and other various water pipes are, in principle, of the rear casing 70b of the divisible casing 70. On the other hand, except for the calcium solution tank 3a, electric components such as the control circuit R and the transformer 91 that dislike water are attached to the front casing 70a. Therefore, even in the unlikely event of water leakage, it is possible to maintain the operation of the electrolysis water purifier A and prevent an electric leakage accident or the like as much as possible.

Further, in the assembled state of the casing 70, the water-related parts are arranged on the right side and the electric-related parts are arranged on the left side in a concentrated manner, respectively, as viewed in FIG. be able to.

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

(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 and 11.

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 has the first communication passage 58 and the second communication passage 59 in the flow passage switching device 41. Through which the alkaline water outlet channel E communicates with the downstream side of the raw water supply channel C, while the alkaline water outlet channel E communicates with the alkaline water outlet channel F through the fourth communication channel 63 in the channel switching device 41.

As shown in FIG. 11 (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. 11 (b), the pressure switch S ₁ is actuated by the supplied water pressure, and a predetermined forward voltage is applied to the electrodes 8 and 9 from the power source 40 via the control device R. As shown in (c), the feed pump 3b is operated to supply calcium to the acidic water tank 13 to generate alkaline water in the alkaline water tank 12 by electrolysis, and at the same time to generate acidic water in the acidic water tank 13. To generate.

Then, the generated alkaline water 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 extraction channel F and used as drinking water. It is possible (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 passage H, and paying attention to its astringent effect, it is used as cleaning water such as hand cleaning water. Can be used as

Next, as shown in FIG. 11 (d), when the cumulative electrolytic water conditioning time calculated by the timer e in the controller R exceeds the set time (for example, 40 minutes), the electrode cleaning display run L ₂ lights up and informs the user that the electrodes 8 _and 9 need cleaning.

When the user presses the electrode cleaning switch S ₃ as shown in FIG. 11 (e) when the electrode cleaning indicator lamp L ₂ is lit, the control signal from the controller R causes A reverse voltage is applied to the electrodes 8 and 9 from the power supply 40 (FIG. 11 (f)), and the deposits attached to both electrodes 8 and 9 can be dissolved and removed. The acidic water after cleaning 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 outlet channel F. (FIG. 11 (h)) After washing, the alkaline water can be discharged to the outside through the acidic water outlet channel H.

While the above-described electrolytic cleaning operation is continuing, the electrode cleaning indicator lamp L ₃ is lit to inform the user of that fact (FIG. 11 (g)).

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

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

After that, when the user reopens the tap water supply unit 1 such as a faucet, the pressure switch S ₁ is turned on as shown in FIG. The electrodes 8 _and 9 can be completely cleaned by applying a reverse voltage to the electrodes 8 and 9 to clean the electrodes (FIG. 11 (f)).

After the remaining electrode cleaning time has elapsed, neither forward nor reverse voltage is applied to both electrodes 8 _and 9 again, and electrode cleaning (reverse electrolysis) is not performed as shown in FIG. 11 (f). It is possible to carry out safe water discharge in which only purified water flows out from the alkaline water extraction flow path F (Fig. 11 (h)).

The reason for doing this is that the water immediately after electrolytic cleaning may be a mixture of cleaning waste water and purified alkaline water, so there is no indication of alkaline water and it is considered that the user will not drink.

[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), the same time when the main electrode cleaning display lamp L ₂ turned It is possible to stop the voltage application to the electrolytic water conditioner A, discharge the electroless water, and prevent the deterioration of the electrodes 8 _and 9 from proceeding.
