[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for producing electrolytic ionized water capable of separately collecting alkaline ionized water and acidic ionized water, and more specifically, by fixing and fixing electrolytic cell unit panels of the same shape on the front and back sides. The present invention relates to a device for generating electrolytic ionized water having a compact shape that can be easily assembled.

2. Description of the Related Art Water containing alkaline ions such as calcium, sodium, magnesium and potassium is delicious, and at the same time, it functions effectively to maintain health by supplementing the lack of alkalinity and minerals in the human body. Commercially available as drinking water. Further, as a device for easily and efficiently producing this kind of alkaline ionized water, an electrolytic ionized water producing device for home and business use has been developed and rapidly spread.

Usually, the electrolytic ionized water generator is used alone or with a water purification system such as an activated carbon filter tank connected to a tap, and its mechanism is such that a pair of electrode plates serving as an anode and a cathode are spaced from each other. It consists of an electrolytic cell isolated by an ion-exchange membrane. During running water, alkaline ion (cation) water generated by ionization of the electrolyte dissolved in water is from the cathode cell, and acidic ion (anion) water is from the anode cell. Designed to be harvested. The apparatus forms are roughly classified into a laminated structure using a plate electrode and a tubular structure using an annular electrode, but a laminated structure in which the number of arrayed electrolytic cells can be increased to increase the production capacity is predominant.

The conventional ionized water electrolysis apparatus having this laminated structure has an electrode plate, an ion exchange membrane,
The electrode plate and the ion-exchange membrane are fixed in a sealed manner through a fixed interval until a predetermined number of tanks are formed, and the electrode plate and the ion-exchange membrane are set in a box container having a water inlet and a water outlet. Therefore, the assembly process of each member is complicated and the work efficiency is poor, and the disassembling work at the time of maintenance such as replacement of parts also requires a lot of work, resulting in a drawback that the process cost increases.

Further, in order to remove the alkali hydroxide component that adheres to the cathode surface as a scale over time during the use process, it is necessary to change the polarity of the electrode and backwash it after using the device. In this case, acidic ionized water comes out from the alkaline ionized water outlet, and alkaline ionized water comes out from the acidic ionized water outlet.Therefore, it is necessary to stop water sampling during washing, but it is necessary to use a means for switching to the running water system. There has been proposed an ionized water generation device (Japanese Patent Laid-Open No. 4-74585) in which continuous operation is possible without stopping the operation by additionally providing a water channel switching means. However, the structure of the water channel switching means is not installed in a part of the array panel in the unit panel type electrolytic cell.

[0006]

As described above, in the electrolytic ionized water producing apparatus having the conventional structure, it takes a lot of time to assemble and disassemble, and the electrolytic cells arranged in a fixed stack are housed in the case container, so that the arrangement of the electrolytic cells is arranged. Since the number of stages is fixed, the electrolytic production capacity cannot be adjusted by increasing or decreasing the number of tanks. Further, the electrolytic cell unit becomes relatively thick, which makes it difficult to design a compact structure.

The present invention was developed in order to solve the above problems of the prior art, and its purpose is to easily and increase / decrease by stacking and fixing electrolyzer unit panels formed in the same shape on the front and back sides. Another object of the present invention is to provide a device for producing electrolytic ionized water having a compact structure that can be assembled into a unit.

[0008]

The electrolytic ion water producing apparatus according to the present invention for achieving the above object comprises a frame-shaped resin frame body having a plurality of connecting solid holes at predetermined positions on the outer periphery thereof. O-ring grooves are formed along the outer peripheral surface at the peripheral portions of both sides of the frame, and partition wall grooves are formed at the inner edges of both sides of the frame, and one is provided at a predetermined position between the O-ring groove and the inner edge located at the top of the frame. The same shape as the front and back sides by integrating the electrode plate into the support member that has two water flow holes that communicate with the inside of the tank, with the tip of the electrode terminal protruding and the electrode surface exposed to the frame space surface excluding the lower part. The electrolyzer unit panel of 1 is formed, and the desired number of the electrolyzer unit panels are laminated so that the anode electrolyzer and the cathode electrolyzer are mutually arranged through the O-ring and the ion exchange membrane, and the water inlets are provided on both sides. Communication with the inlet side outer lid and the water flow hole of the anode electrolyzer A constitutional feature is a structure in which a water-side outer lid having an acidic ionized water outlet and an alkaline ionized water outlet communicating with the water flow hole of the cathode electrolyzer is abutted and hermetically fixed by the connection fixing hole of the supporting member. .

As the electrode plate constituting the electrolytic cell of the present invention, a normal metal electrode formed of, for example, a stainless plate or a titanium plate can be used. Particularly, the surface is plated with a noble metal such as platinum and baked. A titanium electrode coated by means such as the above is preferably used. When any of these electrode materials are used, it is preferable that the electrode plates of the anode electrolysis tank and the cathode electrolysis tank are made of the same material in terms of durability life and device assembly. An electrode terminal made of the same material is spot-welded to the upper end of the electrode plate.

In the electrolytic cell unit panel, both side edges of the electrode plate and intermediate portions of the electrode terminals are buried, and both surfaces of the electrodes are integrally formed on the resin frame body of the supporting member in a state of being exposed on the frame space surface except the lower portion. It is formed by Each electrolytic cell unit panel formed in this way is a unit member having the same shape on the front and back sides as an anode electrolytic cell and a cathode electrolytic cell. Therefore, the O-ring is fitted in the O-ring groove of the support member, the ion exchange membrane is fitted in the groove for the partition wall at the same time, and a predetermined number of sheets are alternately superposed, and the water inlet side outer lid and the water outlet side outer lid are arranged on both sides. It is assembled as a generator of electrolytic ionized water by hermetically fixing it.

In the structure of the present invention, in order to always let out the same generated ion water from the same water outlet even when the polarity of the electrode is changed, the inside of the water outlet side lid or a separate member is prepared. The ion water flow path switching mechanism can be formed on a resin panel that can be stacked and arranged between the electrolytic cell unit panel and the water outlet side outer lid. As a specific flow path switching mechanism to be formed, a flow path from the water flow hole of the anode electrolysis tank to the acidic ion water outlet and a flow path from the flow water hole of the cathode electrolysis cell to the alkali ion water outlet communicate with each other. It is possible to have a structure in which a branch path is formed and a pair of flowing water switching valves that interlock and open according to polarity switching are provided at appropriate positions of the branch path.

As another flow path switching mechanism, a horizontal hole-shaped space portion where the water flow hole of the anode electrolysis cell and the water flow hole of the cathode electrolysis cell communicate with each other, and an acidic ion water outlet at a position opposite to the water flow hole side of the space portion. A flow path leading to the acid ion water outlet and a flow path leading to the alkaline ion water outlet are alternately switched by moving left and right in conjunction with polarity switching in the space portion. It is also possible to set the structure to be equipped with the flow path switching valve, and this mechanism is structurally simple compared to the above-mentioned branch path system.

[0013]

In the electrolytic ionized water production apparatus according to the present invention, since the front and back members having the same shape in which the electrode plates are integrated with the supporting member made of the frame-shaped resin frame are formed as the electrode tank unit panel, Extremely efficient by stacking multiple sheets of electrolyzer unit panels alternately with the O-ring and the ion-exchange membrane side by side and stacking the water-side outer lid and the water-side outer lid on both sides and fixing them together. Assembly work can be performed. Therefore, the assembling process is significantly simplified, and by adjusting the number of stacked layers, it is possible to adapt to a desired capacity according to the production capacity of ionized water to be electrolyzed. Moreover, since the individual electrolytic cell unit panels are formed in a thin plate shape, the overall electrolytic cell unit panel is extremely compact and can be designed in a convenient form for carrying, installation, and the like.

If a flow path switching mechanism is formed in a panel that can be stacked inside the water-side outer lid or between the electrolytic cell unit panel and the water-side outer lid, it can be linked to the polarity switching of the electrodes during use. Due to the action of the flow path switching, the generated alkaline ionized water always flows out from the alkaline ionized water outlet, and the generated acidic ionized water flows out from the acidic ionized water outlet. Therefore, in order to remove the scale adhering to the electrode surface on the cathode side, even if the polarity of the electrode is changed after each use or during use, the outlet of the generated ionic water will not be reversed,
Also, the durability life of the electrode plate is significantly improved. Since the flow path switching mechanism is formed on the resin panel which is slightly thicker than the outer lid or the electrolytic cell unit panel, the compactness and the appearance are not impaired.
