Abstract

PURPOSE:To improve the electrolytic efficiency of an ionized water forming device by setting the electrolytic level applied accross the second anode present between a first anode and the diaphragm and the second cathode present between a first cathode and the diaphragm so as to make the same equal to or higher than the electrolytic level applied across the first anode and the first cathode to alternately output the electrolytic levels of two systems. CONSTITUTION:An anode A2 is disposed between an adode A1 and a diaphragm and a cathode C2 is disposed between a cathode Cl and the diaphragm. The electrolytic level applied across the anode A2 and the cathode C2 is set so as to be equal to or slightly higher than the electrolytic level applied across the anode A1 and the cathode C1. A control part 3 controls the application timings of the electrolytic levels of these two systems on the basis of the timings of the electrolytic levels alternately applied across the anode A1 and the cathode C1 and across the anode A2 and the cathode C2. Or, the outputs of the electrolytic levels of two systems are controlled in a partially superposed state. By this method, electrolytic efficiency is enhanced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ion water generator, and more particularly to an ion water generator having a two-pair electrode structure for increasing electrolysis efficiency.

[0002]

2. Description of the Related Art FIG. 4 is a block diagram of a conventional ion water generator. When tap water flows in from a faucet, a water pressure switch 21 is activated, and a control unit 23 (microcomputer) turns on an electrolytic on / off switch 27. Then, the electrolysis level corresponding to the set PH is applied from the electrolysis power supply 25 between the anode (+) and the cathode (−) of the electrolysis tank 22. The inflow water is filtered by the water purifier 20 to which calcium is added, and the water is supplied to the electrolysis tank 22 for electrolysis. The alkaline ionized water and the acidic water produced by electrolysis are taken out from the respective outlets and used.
When the water supply is stopped and the electrolysis is completed, the control unit 23 switches the cleaning switch 26 to apply a voltage of the opposite polarity to the electrolytic cell 22 to perform electrode cleaning for a certain period of time. If an overcurrent flows during the operation of the electrolytic cell 22, it is detected by the current sensor 24 and protection processing such as electrolysis stop is performed.

[0003]

However, in the prior art shown in FIG. 4, since the electrode structure of the electrolytic cell 22 is composed of a pair of an anode and a cathode with a diaphragm sandwiched between them, the electrolysis efficiency is low and the PH is low. If you want to raise or generate strongly acidic water,
There was a problem such as the power generation.

The present invention has been made in view of the above-mentioned problems, and the electrode structure is made into a two-pair structure, and the synergistic effect of dispersing the electrolytic power in the form of parallel operation and various ion control effects by the two-electrode structure. It is an object of the present invention to provide an ionized water generator that improves electrolysis efficiency by its action.

[0005]

In order to achieve the above object, the present invention provides an ion water generator for producing alkaline ionized water and acidic water by applying an electrolysis power supply between an anode and a cathode of an electrolytic cell to perform electrolysis. In, a second anode provided between the first anode and the diaphragm, a second cathode provided between the first cathode and the diaphragm, constituted by the first anode and the first cathode and the second anode and the second cathode. And an electrolytic power source for outputting two systems of electrolytic levels applied to the two pairs of electrodes, and an electrolytic level for applying an electrolytic level between the second anode and the second cathode between the first anode and the first cathode. A control unit is provided that is set to be equal or higher, and performs timing control for alternately outputting or partially superimposing the electrolysis levels of the two systems.

[0006]

With the above structure, the control section has a two-electrode structure of the first anode and the first cathode and the second anode and the second cathode, and the control unit controls the electrolytic level applied to the second anode and the second cathode. The electrolysis efficiency of the electrolyzer is controlled by setting the electrolysis power supply to the same or higher level than the electrolysis levels for the one anode and the first cathode, and performing the timing control to alternately or partially output the electrolysis levels of these two systems from the electrolysis power supply. Is improved.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an ionized water generator according to an embodiment of the present invention. FIG. 2 is an explanatory diagram of the electrolysis level application timing in the embodiment of FIG.

In this embodiment shown in FIG. 1, a first anode A1 and a first cathode C1, a second anode A2 and a second cathode C2 (anode A2
If the cathode C2 and the cathode C2 are plate electrodes, many holes 4 are formed.)
An electrolysis power source 2 including an electrolysis cell 1 having a two-electrode structure by these, a power supply circuit for applying an electrolysis level to the anode A1 and the cathode C1, and a power supply circuit for applying an electrolysis level to the anode A2 and the cathode C2. And a control unit (microcomputer) 3 that controls the output timing by setting the electrolysis levels of the two systems in the electrolysis power supply 2.

The operation will be described below with reference to the drawings. When the electrolyzer 1 is supplied with water from the water purifier, the control unit 3 outputs P
The electrolysis level corresponding to H is set in the electrolysis power supply 2. In this case, since the set electrolysis level is in the form of parallel drive by two counter electrodes, it is possible to set the electrolysis current to be lower than that of one counter electrode with the same PH, and the electrolysis current flowing through each electrode is dispersed. The current per electrode is small. In addition, with respect to the electrolytic level applied between the anode A1 and the cathode C1, the anode A
2, the level of electrolysis applied between the cathode C2 is set equal or higher.

The control unit 3 controls the application timing of the electrolysis level of these two systems at the timing of alternately applying between the anode A1 and the cathode C1 and between the anode A2 and the cathode C2 as shown in FIG. 2 (a). To do. By doing so, as shown in FIG. 1, the hydroxide ion OH ⁻ and the oxonium ion H ₃ O ⁺ generated in the anode A1 and the cathode C1 undergo a reverse reaction and disappear before disappearing. By applying an electrolysis level in between, each ion can be attracted. The electrical conductivity of these ions is (about Na ⁺ = 50,
(H ⁺ = 350, OH ⁻ = 200) Remarkably large as compared with other ions, and since it is an ion that greatly affects PH, effective control is performed.

Alternatively, the electrolysis level application timing may be controlled in such a manner that the outputs of the electrolysis levels of the two systems are overlapped by one portion (range within the dotted line) as shown in FIG. 2 (b). At the time of the portion W where the electrolysis levels of the two systems overlap, the electric field between the anode A1 and the anode A2 and the electric field between the cathode C1 and the cathode C2 on both sides of the diaphragm 12 (indicated by a thick dotted line) in the electrolytic cell 1. The directions are opposite to the directions of the electric fields at the times when they do not overlap. Therefore, the alternating current is applied, and the accelerator effect of destroying and activating the water clusters is generated, and the electrolytic reaction can be further enhanced. Of course,
It is also possible to apply them simultaneously without shifting the timing of the electrolysis levels of the two systems. In this case, the electrode area becomes larger than that in the case of one pair, so the electrolysis efficiency also increases. These timing controls are appropriately selected.

FIG. 3 is a block diagram of an ion water generator using an electrolytic cell having a two-pair electrode structure as another embodiment of the present invention. In the ionized water generator, there is a problem that the pH of the generated alkaline ionized water momentarily rises, but the pH immediately drops. This is because a current flows and the PH increases for a moment, but the ions of H ⁺ and OH ⁻ are immediately recombined to return to a stable water molecule state, and as a result, the PH decreases immediately.

In order to prevent this, an electrolytic cell having a two-pair electrode structure as shown in FIG. 1 is used for the electrolytic cell 1 of FIG.
An anion (Cl ^−, etc.) and a cation (Na ⁺ ,
(Mg ⁺ ) is brought closer to the diaphragm 12 to raise the electrolytic reaction, the amount of each ion of tap water is checked by the ion sensor 7, the data is A / D converted by the A / D converter 6, and the control unit 8 outputs the data. The electrolysis is judged and the electrolysis is controlled, the PH of the produced water after a certain time is detected by the PH sensor 10, and P is detected.
When H is lowered, the flow rate of the water is adjusted by the flow switch 5, and a warning display for reducing the flow rate is displayed on the display unit 9 for the user.

There is an effect that electrolysis efficiency is increased due to an increase in electrode area and the like, and strong acidic water can be generated.
