2. Description of the Related Art Recently, in combination with nature-oriented and health-oriented, there is a strong interest in water, famous water from all over the country has been commercialized, household water purifiers have become widespread, and even healthier and tastier water is available. An electrolyzed water generator is provided for obtaining. Also,
Strongly acidic water having a low PH and a high redox potential obtained by adding a small amount of chloride to water has excellent bactericidal properties and is beginning to be noticed in various fields such as medical care, food, livestock, and agriculture. There are two types of this electrolyzed water generator, a continuous type directly connected to the water supply and a water storage type.

In the electrolyzed water generator, positive and negative electrodes are soaked in water so as to face each other through a diaphragm to form an electrolytic cell. When an electric current is applied to the electrodes, cations dissolved in water are discharged to the cathode side. The anions move to the anode side, and simultaneously, the electrolysis of water turns the cathode side water into alkaline water and the anode side water into acidic water, which are used respectively.

Conventionally, in an electrolytic cell of a continuous electrolyzed water generator, a plate-shaped electrode is arranged at a narrow interval with a paper-shaped diaphragm interposed therebetween to form a cathode cell and an anode cell, respectively, and a plurality of them are laminated. Or, arrange the anode round bar in the center, and arrange the cylindrical diaphragm and the cylindrical cathode at a narrow interval on the outside, or a configuration in which they are concentrically stacked,
Alternatively, a structure of an electrolytic cell such as a configuration in which a plurality of electrode cells having the same structure are connected in parallel has been adopted.

[0005]

However, in the electrolytic cell of the continuous electrolyzed water generator, the plate-shaped electrodes are arranged with the paper-like diaphragm interposed therebetween to form the cathode cell and the anode cell, respectively.
When laminating a plurality of these layers to perform multi-stage lamination, water is supplied to each cathode tank and anode tank separated by a diaphragm, and electricity is alternately supplied as a cathode and an anode, and water from each cathode tank and anode tank is supplied. It is necessary to separate and take out.

On the other hand, in order to increase the electrolysis efficiency and to narrow the distance between the cathode and the anode, each electrode tank has a narrow structure.
The structure of energizing the electrodes of each electrode tank, the structure of supplying and extracting water, etc., becomes more complicated as the number of electrode tanks increases, obstructing the flow of water and making the water flow uniform and the cathode and anode tanks uniform. There was a problem that the separation was not performed reliably.

Therefore, it is an object of the present invention to provide an electrolysis cell having a high energization efficiency by facilitating the energization structure, the water supply and extraction structure, etc. to each electrode cell when a plurality of electrode cells are laminated.

[0008]

In order to solve the above-mentioned problems, the present invention electrolyzes water to collect alkaline water at the cathode and acidic water at the anode so that they can be distinguished and taken out. In the generator, the cathode tank and the anode tank have the same structure, and the plurality of tanks are alternately inverted and stacked via a diaphragm, and the stacked ones are integrally housed in an insulating casing. Further, a recess is formed inside both short sides facing the opening, one end of the electrode plate is inserted into the recess through the opening of each short side, and the other end of the electrode plate is formed. To project from the rectangular frame to form an electrode chamber, and a plurality of such electrode chambers are alternately inverted and stacked with a diaphragm interposed therebetween to be housed in a predetermined casing, and an electrode plate projecting from the rectangular frame. A structure in which a power source is connected to the rectangular frame, a cutout is formed outside the central portion of the short side of the rectangular frame, and a partition that fits into the cutout is formed. Furthermore, the casing is arranged in point symmetry around the partition. A structure is provided in which a water supply port and a water intake port are provided.

[0009]

According to the present invention having the above-mentioned structure, the electrode baths are alternately inverted and stacked with the diaphragm interposed therebetween so as to be stacked in an arbitrary number of stages, and the cathodes which are aligned on one side and the anodes which are aligned on the other side are separated by the partition walls. Are connected with terminal rods, each of which is connected with an electrode terminal, is housed in a casing, and water is supplied, alkaline water is aligned from one side of the cathode tank to the other side of the anode tank. Acid water can be separated and taken out from the intake of each. Further, since the plurality of cathode layers and the anode layer constituting the electrolytic cell have the same structure, a space is small when they are stacked in multiple layers, and each electrode layer can be integrated to stack any number of layers. Further, since the cathode layer and the anode layer have symmetry, the water flow is not obstructed, and the water flows into each electrode layer with an equal amount of water, so that the cathode and the anode can be reliably separated.
