Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a sterilizing electrolytic ion generating device that electrolyzes water into alkaline ionized water and acidic ionized water and imparts sterilizing power using negative ions to the generated electrolyzed ionized water. .

[Problem that the invention seeks to solve]

Water is supplied to an electrolytic cell in which a cathode chamber and an anode chamber are separated by an electrolytic diaphragm, and a DC voltage is applied between the electrodes of both electrode chambers to generate alkaline ionized water and acidic ionized water separately. There is a water-type electrolytic ion water conditioner, but although this device activates ions, it does not have sterilizing power. For this reason, there is a problem that it is easily corrupted.

As shown in Japanese Patent Application Laid-Open No. 60-97088, there is an electrolyzer that uses silver for the positive electrode, but since this uses a silver anode for the electrolytic electrode itself, more silver than necessary is used. This is extremely uneconomical as it wastes money.

An object of the present invention is to provide a sterilizing electrolyzed ionized water generating device that is inexpensive and can provide an appropriate amount of silver ions for sterilization.

Another object of the present invention is to provide a sterilizing electrolyzed ionized water generating device in which oxide scale does not adhere to the silver anode of the sterilizing silver ion generating device.

[Means to solve problems]

In order to solve the above problems, the present invention has developed an electroosmosis system that connects an anode chamber with a silver anode electrode and a cathode chamber with a cathode electrode on the downstream side of an electrolytic ion water conditioner, that is, on the produced ion water outlet side. A silver ion generator partitioned by a diaphragm is installed, and one of the alkaline water outlet and the acidic water outlet of the electrolytic ion water conditioner is connected to the cathode chamber of the silver ion generator via a water channel. The other water intake of the electrolytic ion water conditioner was connected to the cathode chamber of the ion generator through another waterway, so that sterilizing ions were applied to the ionized water produced by electrolysis. It is something. In particular, in an embodiment in which acidic water from the electrolytic ion water conditioner is introduced into the anode chamber of the ion generator, it is possible to prevent scale from adhering to the silver anode.

In the figure, reference numeral 12 denotes a support member that holds the diaphragm 9 at a predetermined partitioning position, and is used as a reinforcing material especially when the diaphragm is thin like a film. In the embodiment shown in the figure, a cylindrical outer frame is used as a negative electrode 7 made of stainless steel or the like, and a rod-shaped or cylindrical silver positive electrode 6 is arranged in the center. In contrast to this, the inner wall of the outer frame is a silver electrode, and a negative electrode made of stainless steel or the like is placed facing each other in the center to form an anode chamber and a cathode chamber. You can change it. Furthermore, the silver ion generator of the present invention is not limited to the cylindrical shape as shown in the figure, but may be of any shape such as a flat plate as long as the space between both electrodes is divided into an anode chamber and a cathode chamber by an electroosmotic diaphragm. .

Thus, in the device of the present invention, either the alkaline water outlet 3 or the acidic water outlet 4 of the electrolyzed ionized water generator 1 (hereinafter referred to as an electrolyzer) is connected to the anode chamber 10 of the negative ion generator 5 having the above configuration. It is connected to the water supply port 10a via a water channel 13, and the other water intake port of the electrolyzer 1 is connected to the water supply port 113 of the cathode chamber 11 of the silver ion generator 5 via another water channel 14. .

The raw water introduced into the electrolyzer 1 from the water supply pipe 2 is distributed to the cathode chamber and the anode chamber of the electrolyzer 1, and the raw water is distributed between the two electrodes. Electrolysis is carried out by applying a high DC voltage to the electrode, and ion exchange is performed by the electrolytic diaphragm to produce alkaline ionized water in the anode chamber and acidic water in the cathode chamber.

Alkaline ionized water and acidic ionized water derived from the electrolyzer 1 are sent separately to the cathode chamber 10 or the cathode chamber 11 of the silver ion generator 5 via water channels 13 and 14. In this state, by applying a DC voltage between the silver positive electrode B and the negative electrode 1, negative ions Ag'' are released into the ionized water in the electrode chamber, and a part of them passes through the diaphragm 9 and enters the cathode chamber. Therefore, the silver ion generator separately generates sterilized and imparted sterilized 'ITi' and decomposed alkali ionized water.

In the embodiment shown in the figure, one electrolyzer is connected to one ion generator, but multiple electrolyzers can be connected to one ion generator. Of course, these are also included within the scope of the present invention.

〔Effect of the invention〕

In the present invention, since the electrolyzed alkaline ionized water and the acidic water are given negative ions, the electrolyzed water is sterilized and, at the same time, it is possible to obtain the electrolyzed ionized water that is less susceptible to spoilage due to the residual silver ions.

Furthermore, since the anti-ion generator is used only to impart sterilizing power, the consumption of silver anodes is small, making it significantly more economical than an electrolytic device that uses silver for its own positive electrode.

Furthermore, when the acidic water produced by the electrolyzer is passed through the silver anode chamber of the silver ion generator, the adhesion of an oxide film to the anode electrode is prevented, resulting in an efficient sterilization effect.
