Description

Electrolyte for ionized water production

The present invention relates to an ionizer for obtaining alkaline water by electrolyzing tap water, and more particularly, to an electrolyzer for producing ionized water for decomposing tap water into acidic and alkaline water in the ionizer.

In general, water purifiers that purify tap water are composed of ganban stones (Korean Patent Publication No. 90-2824), those formed by filtration using a semipermeable membrane (Korean Patent Publication No. 95-16843), zeolites, and the like. Using a filter filled with a molecular sieve (Korea Patent Publication No. 96-4231), Using a material that adsorbs heavy metals and organic matter, such as activated carbon as a filter (Korean Patent Publication No. 13423) It adopts the method of filtration using the water purifying filter of the material or adopts the reverse osmosis method (Korean Patent Publication No. 21201) to remove the floating matters and other contaminants contained in the tap water to drink the purified water. have.

However, these water purifiers provide some clean water when the filter to purify the tap water is not contaminated, but when the filter is contaminated due to long-term use, the purified water is rather contaminated by bacteria, so it is fully functional as drinking water. Could not expect.

In view of the problems described above, an ion water group for producing acidic and alkaline water is formed by electrolyzing tap water without water purification by a filter to form hydroxide ions and hydrogen ions. Korean Patent Publication No. 95-5755, 95-31922 No. 96-4225 and 96-17535.

1 is a longitudinal cross-sectional view showing the structure of an electrolyzer for producing ionized water in general, a circular cylindrical cathode 1 having a chamber 2 formed therein, a cylindrical rod-shaped anode 3 provided to be spaced apart from the cathode in the chamber, and the cathode Tap water flows in between the ion exchange membrane 4 made of ceramic interposed between (1) and the anode (3), the anode (3) and the ion exchange membrane (4), and the cathode (1) and the ion exchange membrane (4). Inlet pipes (5) and (6) are installed so as to support both ends of the anode (3) and the cathode (1), and the coupling portion of the bush (7), the anode (3) and the cathode (1) It consists of the sealing material 8 which seals.

The electrolyzer of this structure flows into the inside of the chamber 2 through the inflow pipes 5 and 6 in which the tap water is formed in the bush 7.

Tap water introduced into the chamber 2 passes through the chamber 2 formed between the anode 3, the cathode 1, and the ion exchange membrane 4 to the anode 3 and the cathode 1. An electric current is flowing and organic matter and heavy metals are removed by an electrochemical reaction.

In particular, organic matter is removed from the anode 3 through the ion exchange membrane 4, and heavy metals and the like are removed from the cathode 1, so that desired alkaline water can be obtained.

Conventional electrolyzers having such a structure have a problem that it takes a long time to obtain a large amount of alkaline water because alkaline water is obtained by one cathode and an anode, which is rarely used in recent years.

Therefore, in order to solve the above problems, a plurality of positive electrode plates and negative electrode plates are sequentially inserted into the divided housing, and at the same time, they are separated by an ion exchange membrane to obtain a large amount of acidic and alkaline water in a short time. In addition, several problems have occurred.

First, a low voltage (10V or less) should be applied so that the positive electrode plate does not dissolve during electrolysis of the inflowed water. To this end, the gap between the positive electrode plate and the negative electrode plate must be kept narrow, but there is a limit to the adhesion between the positive electrode plate and the negative electrode plate in the housing. Since the distance between the two is forced to apply a voltage of about 20V has a fatal defect that the anode plate made of platinum is dissolved.

Secondly, as the electrolyzer is used for a long time, calcium carbonate generated during electrolysis sticks to the negative electrode plate so that no current flows through the negative electrode plate, thereby making it impossible to obtain alkaline water from the electrolyzer.

Third, since the positive and negative plates are plate-shaped, hydrogen and oxygen gas generated during electrolysis do not pass between the positive and negative plates to generate bubbles, so alkaline or acidic water produced by electrolysis cannot be discharged to the outside of the electrolyzer. There was a failure.

Fourth, since the positive electrode plate, the negative electrode plate and the ion exchange membrane are molded in the housing and shipped in a standardized state, an electrolyzer having a different capacity must be purchased according to the capacity of the alkaline water to be obtained.

The present invention has been made to solve such a conventional problem, it is possible to freely configure the size of the electrolyzer according to the capacity of the alkaline water to be obtained by disassembling and assembling the electrolyzer, and at the same time Even if calcium carbonate adheres to the electrolytic plate due to prolonged use, it is intended to decompose the electrolyzer to remove the calcium carbonate from the electrolytic plate so that it can be reused.

Another object of the present invention is to narrow the gap between the positive electrode plate and the negative electrode plate and the ion exchange membrane to electrolyze the incoming water even when a low voltage is applied.

According to the aspect of the present invention for achieving the above object, the tap water inlet is formed on one side, the acid and alkaline water outlets are formed side by side on the other side and the front plate formed with a packing insertion groove on one side, and a through hole is formed therein At one side, the discharge hole is formed to match the outlet, and at the other side, the discharge hole is formed through the through hole in accordance with the outlet, and the packing insertion groove and the ion exchange membrane insertion groove are formed at both sides, so that each discharge hole is coupled in a zigzag position on the front plate. A plurality of diaphragms, an electrolytic plate inserted so that the tap water inlet is visible inside each of the diaphragms, and a terminal exposed to the outside of the diaphragm, and an ion exchange membrane installed in the ion exchange membrane insertion grooves formed in the diaphragms to pass only ions; A packing inserted in each of the packing insertion grooves to maintain airtightness, and assembled to a final diaphragm Groups for producing the electrolytic water, characterized in that the fastening means consists of a seal groove and the rear plate, the face plate and integrated with the rear plate and the plate is formed on the contact face of the is provided.

The electrolytic plate 20 is inserted into the front plate 10 so that the tap water inlet 11 is visible inside the diaphragm 16 coupled to each of the discharge holes 18a and 18b in a zigzag position. Although the terminal 20a extending from the electrolytic plate 10 is exposed to the outside of the diaphragm 16, power is applied through the terminal 20a.

A plurality of holes 21 are formed on the electrolytic plate 20, which allows the gas generated during electrolysis to cross between the electrolytic plates 20 to discharge acidic and alkaline water through outlets 12a and 12b. This is to make this smooth.

In addition, an ion exchange membrane 22 for passing only ions generated during electrolysis is provided in the ion exchange membrane insertion grooves 19 formed in each of the diaphragms 16, and each packing insertion groove 13 has an airtight packing ( 23 is inserted, the protrusion 13a is formed at the corner of the packing insertion groove 13, and the packing 23 is formed with a hole 23a fitted to the protrusion.

It is fitted in the guide groove 28 formed in the position is determined so that the rapid assembly is possible.

After assembling one diaphragm 16 on the front plate 10 as described above, the ion exchange membrane 22 is positioned in the ion exchange membrane insertion groove 19 formed to be adjacent to the through hole 17, and at the same time, the packing insertion groove 13 is provided. The new packing 23 is placed in the stack and another diaphragm 16 is stacked. In this case, the diaphragm 16 in which the discharge hole 18b formed through the through hole 17 is already assembled to the front plate 10. Since it is assembled with the discharge hole (18a) of the mutually opposite, the terminal 20a of the electrolytic plate 20 is also located in a zigzag.

Accordingly, the rod-shaped protrusion 30 located on one side of the diaphragm 16 is inserted into the insertion groove 31, so that a quick assembly operation is possible.

After stacking the proper number of diaphragms 16 in a zigzag according to the capacity of the alkaline water to be obtained in this manner, the packing 23 is placed in the packing insertion groove 13 of the final diaphragm 16, and then the back plate 24 is placed.

Then, the calcium carbonate adhering to the electrolytic plate 20 with an acid (vinegar, etc.) solution is cleaned and then recombined so that it can be used again.

As described above, the present invention has several advantages as compared to the conventional electrolyzer.

First, the electrolytic electrolytic plate is inserted into the diaphragm, and the spacing between the electrolytic plates is determined by laminating the diaphragm so that the spacing between the electrolytic plates (formerly 5 mm or more and the present invention: 2 mm or less) can be kept narrow. The application of the voltage becomes possible, thereby preventing the phenomenon in which the electrolytic plate to which -voltage is applied is prevented.

Second, as the electrolyzer is used for a long time, it is possible to disassemble and assemble the electrolyzer even if the calcium carbonate generated during electrolysis adheres to the electrolyzed plate to which the voltage is applied, thereby eliminating the calcium carbonate stuck to the electrolyzer. It is possible to extend the life of the.

Third, even though hydrogen and oxygen gas are generated between the electrolyzer electrolytic plates, holes are formed in the electrolytic plates so that they pass through the electrolytic plates so that alkaline or acidic water produced by electrolysis can be smoothly discharged to the outside of the electrolyzer.

Fourth, the diaphragm laminated between the front plate and the back plate consists of a single piece, so the capacity of the electrolyzer is increased by simply adjusting the number of plates according to the capacity of the alkaline water to be obtained. do.
