Abstract

PURPOSE:To offer an electrolyzed water straightening equipment with which alkali water or acid water can be obtained by the same amt. as that of supplied source water without largely changing pH of the water in the electrolysis cell to be used by selectively opening and closing a neutralizer supplying circuit comprising two systems, one being to supply a neutralizer for acid to the cathode room in the electrolytic cell and the other being to supply a neutralizer for alkali to the anode room. CONSTITUTION:A neutralizer supplying circuit 9 from a tank 13 of neutralizer for alkali water is opened with a valve device 11. Then the neutralizer for alkali water is introduced to the cathode room 2 by a pump 14. On the other hand, a neutralizer supplying circuit 10 from a tank 12 of a neutralizer for acidic water is closed with a valve device 11. Acidic water from the anode room 3' and neutralized water (e.g. neutral water) from the cathode room 2' are joined in a common tube 8 and drained through a water drainer 15 such as a shower head or tap. Since the electrolyzed water in the cathode room 2' is almost neutralized, the joined water is maintained acidic. Thereby, acidic water is discharged from the water drainer 15 by the amt. equivalent to the total amt. of the supplied water.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] In particular, the present invention relates to an electrolytic water conditioning device that neutralizes water in one electrode chamber during electrolysis, merges with electrolyzed water in the other electrode chamber, and discharges the water.

j Problem 8''' that the invention seeks to solve.

Conventional electrolyzed water generation equipment that generates drinking alkaline ionized water or acidic ionized water by electrolyzing water has separate drainage pipes for alkaline water and acidic water, and when using alkaline water, The structure is such that acidic water is disposed of into the drain, and when acidic water is used, alkaline water is disposed of into the drain. For this reason, the yield of electrolyzed water on the user side is poor compared to the amount of raw water supplied from the water supply channel.

An object of the present invention is to provide an electrolytic water conditioning device that selectively obtains the same amount of alkaline water or acidic water as the raw water to be supplied without significantly changing the pH value of the electrolyzed water on the user side.

[Means for Solving the Problems] In order to achieve the object No. 142, the electrolytic water conditioning device of the present invention includes an electrolytic cell in which a pair of electrodes with different polarities is partitioned into a pair of electrode chambers by an electrolytic diaphragm. A water supply pipe is provided on one side of the electrolytic cell, and an electrolyzed water intake pipe is provided on the other side for merging and discharging a pair of electrolyzed water drainage pipes communicating with each of the electrode chambers. electrolyzer, a two-system neutralizer supply circuit that supplies an acidic neutralizer to the cathode chamber of the electrolytic cell, and an alkaline neutralizer to the anode chamber, and a neutralizer supply circuit that supplies two systems in the middle of the two-system neutralizer supply circuit. and a selection valve device that selectively opens and closes these two neutralizing agent supply circuits.

More preferably, the pair of electrodes of the electrolysis device is a cathode capable of continuously electrolyzing by switching the polarity of the applied voltage.
In addition to being composed of an electrode that can be used as an anode, the power supply circuit of the electrolyzer is equipped with a voltage polarity switching control section, and furthermore, the two systems of neutralizing agent supply conduits are connected to these two systems in conjunction with the operation of the voltage polarity switching control section. A switching valve may be provided to switch the flow paths of the two systems of neutralizing agent supply pipes.

In either case, it is desirable to provide a flow ratio adjustment valve in a pair of electrolyzed water intake pipes of the electrolyzer. In particular, in the case of a device that uses both cathode and anode electrodes and performs continuous electrolysis by switching the polarity of the applied voltage, a pair of electrolyzed water drainage pipes in the electrolysis device is linked to the switching of the voltage polarity switching control section. A flow rate ratio adjustment valve is provided to adjust the pair of electrolyzed water drainage flow rates to a predetermined flow rate ratio.

: Effect of the invention] In the apparatus of the present invention, the water in the electrode chamber to which a neutralizing agent has been added is neutralized during electrolysis, and the water in the other electrolyte is electrolyzed to the target alkaline water or acidic water. The electrolyzed water in these picture electrode chambers is combined and discharged from a common water intake, but since the electrolyzed water in one is neutralized, even if it is mixed with the electrolyzed water in the other electrode chamber, the total There are no large fluctuations in pH. Therefore,
The entire amount of supplied raw water is used as the target electrolyzed water (alkaline water or acidic water).

Neutralization of acidic water and alkaline water can be arbitrarily switched by selectively opening and closing two systems of neutralizing agent supply circuits, one for acidic water dispersible and one for alkaline water, using a valve device.

The pair of electrodes of the electrolysis device is composed of a cathode/anode electrode that can perform continuous electrolysis by switching the polarity of the applied voltage, and the power supply circuit of the electrolysis device is equipped with a voltage polarity switching control section, and furthermore, the two systems are If the neutralizing agent supply line is provided with a switching valve that switches the flow paths of these two systems of neutralizing agent supply lines in conjunction with the operation of the voltage polarity switching control section, the voltage applied to the electrode chamber can be changed by switching the applied voltage. The properties of the produced water are reversed, but at the same time, the flow path of the neutralizer is also switched, so electrolyzed water with the desired properties can still be obtained from the water intake faucet.

In this type of electrolyzer, the production ratio (flow rate) of alkaline water and acidic water may be varied depending on the purpose, but this adjustment is controlled by a flow rate ratio adjustment valve provided in a pair of electrolyzed water drainage pipes. In particular, in an electrolytic device that is operated by switching the polarity of the electrolytic voltage, this flow rate ratio adjustment valve operates in conjunction with the switching of the electrode polarity to maintain a predetermined flow rate ratio.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes an electrolytic device equipped with an electrolytic cell 1' in which a pair of electrode chambers 2' and 3' are partitioned by an electrolytic diaphragm 4 between electrodes 2 and 3 of opposite polarity arranged oppositely.

A water supply pipe 5 for supplying raw water such as tap water is provided on one side of the electrolytic cell 1', and electrode chambers 2' and 3 are provided on the other side.
A pair of drain pipes 6.7 are connected to the drain pipes 6 and 7, which communicate with each other individually.

By thus applying a direct current electrolytic voltage from the power supply circuit E to the electrodes 2 and 3, the raw water introduced into the electrolytic cell 1 is electrolyzed.

In the electrolyzer used in the present invention, the pair of drain pipes 67 communicating with the cathode chamber 2' and the anode chamber 3' are merged, and water is taken out from a common water intake pipe 8.

The cathode chamber 2' of the electrolytic cell 1' is equipped with an alkaline water neutralizer supply circuit 9 for neutralizing the alkaline water produced there as required, and the anode chamber 3' is equipped with an alkaline water neutralizer supply circuit 9. A neutralizing agent supply circuit 10 for acidic water is piped therein to neutralize the acidic water generated here as necessary.

The two systems of neutralizing agent supply circuits 9.10 are connected to each corresponding neutralizing agent tank 12.13 via a valve device 11 that selectively opens and closes these neutralizing agent supply circuits 9.10. There is.

The valve device 11 is not limited to the structure illustrated in the figure, but may have any other structure as long as it can be selectively opened and closed so that when one of the two passages 9 and 10 is open, the other is closed. good.

In the state shown in FIG. ', and on the other hand, the neutralizer supply circuit 10 from the acidic water neutralizer tank 12 is closed by the valve device 11. In this state, acidic water is produced in the anode chamber 3' by electrolysis, The water in the cathode chamber 2' is discharged from the drain pipe 7, while the water in the cathode chamber 2' is neutralized to approximately pH 7 or lower by the neutralizing agent from the tank 13, and is discharged from the drain pipe 7.

In this way, the acidic water from the anode chamber 3' and the neutralized water (for example, neutral water) from the cathode chamber 2' are combined into the common water intake pipe 8 and discharged from the water intake part 15 such as a shower or faucet. ,
Since the electrolyzed water in the cathode chamber 2' has been neutralized to approximately neutrality, the water after merging is maintained at an acidic level. Therefore, from the water intake section 15, acidic water corresponding to the total amount of raw water j11 is discharged.

On the other hand, when the valve device 11 is operated to switch the flow path so that the neutralizing agent supply circuit 10 for acidic water is opened and the neutralizing agent supply circuit 9 for alkaline water is closed, alkaline water is discharged from the cathode chamber 2'. The water in the anode chamber 3' is neutralized to approximately pH 7 or higher by the neutralizing agent. Therefore, contrary to the above, the entire amount of supplied raw water is discharged from the water intake section 15 as alkaline water.

The valve device 11 may have a structure in which the switching operation is performed mechanically using a serpentine lever, or may have a structure in which the switching operation is performed electrically by a switch near the mounting portion 15.

Note that the flow rate ratio of the picture electrode chamber is not necessarily constant depending on the nature of the water to be produced. For this reason, it is desirable to provide a flow rate ratio adjustment valve 16 in the pair of drain pipes 6 and 7 (preferably at their confluence) so that the flow rate ratio can be adjusted.

Fig. 2 shows another embodiment of the present invention. In this embodiment, the pair of electrodes 2 and 3 of the electrolytic cell 1' are used as both cathode and anode electrodes that can perform continuous electrolysis by switching the polarity of the applied voltage. At the same time, a voltage polarity switching control section 17 is provided in the power supply circuit E of the electrolysis device 1, and furthermore, these two systems are connected to the two systems of neutralizing agent supply conduits 9 and 1o in conjunction with the operation of the voltage polarity switching control section. This is via a switching valve 18 that switches the flow paths of the neutralizer supply pipes 9 and 10 of the system.

In a water electrolysis device 1, calcium is deposited where alkaline ionized water passes, which tends to cause various problems.

As shown in Figure 2, this problem can be solved by changing the polarity of the voltage applied to the electrode at regular intervals for electrolysis.
Since the electrode chambers are reversed by changing the polarity of the electrodes, it is necessary to switch the flow paths of the neutralizing agent supply circuits 9 and 1o. The switching valve 18 is provided for this purpose, and although it is shown in FIG. 2 on the downstream side of the selection valve device 1 of the neutralizing agent supply circuit, it is of course possible to provide it on the upstream side.

In the embodiment shown in FIG. 2, the polarity is changed to change the power of the cathode into the anode and the anode into the cathode. is not affected by polarity conversion.

Other functions and operations are the same as in the embodiment shown in FIG.

The polarity of the voltage may be switched manually or may be switched automatically when the electrolysis time is accumulated and a predetermined accumulated time is reached.

During electrolysis, a neutralizing agent supply circuit may be used or a separate supply path may be provided to add cosmetic or other chemicals to the raw water.

Although the figure shows an example in which a continuous water flow type electrolyzer is used, the present invention is not limited to this, and the present invention is applicable to batch type electrolysis when producing electrolyzed water. The water on the user side is neutralized and mixed with the water on the user side before being discharged, but since the neutralized water is mixed, the overall pH value does not change significantly. Therefore, the entire amount of supplied raw water can be used from the water intake section as water for the purpose of use (alkaline water or acidic water), so there is no waste.

Moreover, by switching the opening and closing of the neutralizer supply circuit, any electrolyzed water, alkaline water or acidic water, can be selectively taken out from the common water intake port.

Therefore, it can be used for many purposes, and is particularly convenient for continuously performing facial cleansing with alkaline water and treatment with acidic water.
