Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrolyzer for an ion water generator, and more particularly to an electrolyzer for an ion water generator configured to increase the residence time of inflow water to improve electrolysis efficiency.

[0002]

2. Description of the Related Art FIG. 5 is a block diagram of a conventional ion water generator, in which tap water flowing from a tap is purified by a water purifier 5 as indicated by an arrow.
0, is filtered by a filter of activated carbon or a hollow fiber membrane, and is supplied to the electrolytic cell 51 through the water supply pipe 54. When the water supply is detected, the control unit 60 turns on the electrolytic on / off relay 57.
And set the electrolysis level corresponding to the set pH value to the electrolysis power source 5
The voltage is applied between the anode 52 and the cathode 53 from 9 to start electrolysis.
When the electrolysis is started, calcium ions Ca ^{2+ and the} like are collected on the side of the cathode 53 through the permeable diaphragm 61, and hydroxide ions OH
^-, Etc. gather on the side of the anode 52 to generate alkaline ionized water and acidic water. The generated alkaline ionized water is taken out from the outflow pipe 56 and the generated acidic ionized water is taken out from the outflow pipe 55 for use. When the electrolysis ends and the inflow water stops, the control unit 60 switches the cleaning relay 58 to the cleaning side, applies a reverse polarity voltage between the anode 52 and the cathode 53, and performs electrode cleaning for a certain period of time.

[0003]

However, in the prior art shown in FIG. 5, the electrolytic cell 51 has a single anode 52.
Since it is composed of the cathode 53 and the single diaphragm 61, the space between the diaphragm 61 and each electrode is a mere space through which the inflow water passes, and the inflow water flows out through the electrolytic cell 51 at a constant flow velocity. Since the water flows out from the pipes 55 and 56, the residence time between the electrodes of the electrolytic cell 51 is short, and therefore the electrolysis time is short and the electrolysis efficiency is low. In particular, the electrolysis efficiency increases as the amount of inflow water increases. There was a problem that it would be low.

The present invention has been made in view of the above-mentioned problems. By further inserting a diaphragm and a porous ceramic between each electrode and the diaphragm, the resistance against the water flow in the electrolytic cell is increased and the retention is achieved. It is an object of the present invention to provide an ion water generator configured to increase the electrolysis efficiency by increasing the time.

[0005]

In order to achieve the above object, the ionized water generator of the present invention is an alkaline ion ionizer that performs electrolysis by applying an electrolysis voltage between an anode and a cathode separated by a permeation diaphragm of an electrolytic cell. In an ionized water generator that produces water and acidic water, an anode diaphragm inserted between the diaphragm and the anode to increase the electrolysis efficiency of the inflow water flowing into the electrolytic cell,
It is characterized by comprising a cathode diaphragm inserted between the cathode and the diaphragm, and a porous ceramic arranged in parallel with the anode diaphragm and the cathode diaphragm. Further, the ion water generator is characterized in that a constant flow valve or a partition plate is provided in an outflow pipe through which the generated alkali ion water and acid water are discharged.

[0006]

With the above structure, the inflow water supplied to the electrolytic cell is permeated and separated by the electrolysis into the + -ions through the diaphragm, and is also permeated and separated by the anode diaphragm and the cathode diaphragm. The quality ceramic increases the water flow resistance to inflow water in the electrolytic cell, prolongs the residence time, and increases the electrolysis time to improve the electrolysis efficiency. Further, since the flow pipe for flowing out the generated ion water has the constant flow valve or the filter, the water flow resistance due to the inflow water in the electrolytic cell is increased thereby, and the electrolysis efficiency can be improved.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of an ion water generator according to a first embodiment of the present invention.

Next, the operation will be described. Water purifier 50
The tap water that has passed through is supplied from the water supply pipe 54 to the electrolytic cell 7 through the path indicated by the arrow. The inflowing water supply is separated as shown by the arrow, so to speak, the water supply space between the diaphragm 61 which is the first chamber on the anode side and the anode diaphragm 4, and the water supply between the cathode 53 and the cathode diaphragm 2 which is the first chamber on the cathode side. Water is supplied to the space, and from the first chamber on each of the anode side and the cathode side to the water supply space between the anode diaphragm 4 and the anode 52, which is a so-called second chamber, and the water supply space between the diaphragm 61 and the cathode diaphragm 2.

The produced ionized water passes through the acidic water outflow pipe 55 from the space side between the anode diaphragm 4 and the anode 52, and from the space side between the diaphragm 61 and the cathode diaphragm 2 into the alkaline ionized water outflow pipe. Although each is taken out through 56, it is restricted by the constant flow valves 5 and 6 provided in the outflow pipe so that the outflow amount of the alkaline ionized water or the acidic water is constant. As the constant flow rate valve, a type in which the opening / closing degree of the solenoid valve is controlled according to the set flow rate, a type in which the orifice system has a simple structure, or the like is appropriately used. In this way, the outflow amount of the generated water is also limited to a certain amount, so that even if the amount of water supplied from the water supply pipe 54 is increased, the flow velocity is prevented from increasing due to the resistance to the flowing water, and the retention time of the supplied water is prevented from being reduced correspondingly. The electrolysis efficiency can be maintained high without reducing the electrolysis time.

Next, a second embodiment of the present invention will be described. FIG. 2 is a configuration diagram of an electrolytic cell of the ion water generator according to the second embodiment. In the case of FIG. 2, the other structure is the same as the previous embodiment, so only the part relating to the electrolytic cell 8 is shown, and the part different from the first embodiment of FIG. 1 is that there is a gap between the cathode diaphragm 2 and the diaphragm 61. The porous ceramic 1 is provided between the cathode 53 and the cathode diaphragm 2, and the water supplied to the electrolytic cell 8 is supplied from the center on the right side through the water supply pipe 9 and flows into both sides of the diaphragm 61. The point is that it has a symmetrical structure. The operation and effect are similar to those of the previous embodiment.

FIG. 3 is a schematic diagram of an electrolytic cell according to a third embodiment of the present invention. The configuration of the electrolytic cell 10 shown in FIG. 3 is different from that of FIG. 1 in that there is no porous ceramic 3 between the anode 52 and the anode diaphragm 4, and the porous ceramic 3 is between the diaphragm 61 and the anode diaphragm 4. The anode diaphragm 4 and the cathode diaphragm 2 are provided symmetrically with respect to the diaphragm 61, and water is supplied symmetrically to the anode 52 side and the cathode 53 side through the T-shaped water supply pipe 11. is there. The operation and effect are similar to those of the previous embodiment.

FIG. 4 shows a fourth embodiment of the present invention. Here, the case of a U-shaped anode and an I-shaped cathode electrolytic cell is shown. The structure is such that the outside is covered with a U-shaped anode 20, an I-shaped cathode 22 is inserted and fixed in the center, and a U-shaped diaphragm 21 is inserted and attached between the anode 20 and the cathode 22. The overall shape of this electrode body is a prismatic shape that is long in the direction perpendicular to the drawing. Therefore, in this structure, the electrolytic cell can be constructed compactly, and the anode 20 and the cathode 2
2 has a large electrode area and can shorten the electrode tube distance, so that it has the advantage of high electrolysis efficiency.

The water supplied from the water supply pipe through the water purifier flows into the lower portion of the cathode 22 as indicated by the arrow. That is, the lower diaphragm 21 and the lower surface of the cathode 22 and the lower anode 2
It splits into two between the 0 upper surface and flows in. The inflowing water supply is
While being electrolyzed by the electrolysis power source applied between the anode 20 and the cathode 22, the cathode 22 along the U-shaped path in the electrolytic cell.
The generated alkaline ionized water reaches the upper side of the upper side of the upper diaphragm 20, and the generated alkaline ionized water flows out of the alkaline ionized water outlet between the upper surface of the cathode 22 and the acidic water flows out of the acidic water outlet between the lower surface of the upper anode 20 and the diaphragm 21. In this case, since the outflow amount of each ionized water is limited by the constant flow valves 5 and 6, the flow velocity in the electrolytic cell is reduced, the residence time and the electrolysis time are increased, and the electrolysis efficiency is further improved.

Further, as shown in the fourth embodiment, a porous ceramic or a filter may be provided in each of the flowing passages of the alkaline ionized water and the acidic water to increase the flowing water resistance.

[0018]

As described above, according to the present invention, the anode diaphragm inserted between the diaphragm and the anode of the electrolytic cell, the cathode diaphragm inserted between the cathode and the diaphragm, the anode diaphragm and the cathode diaphragm are arranged side by side. Since the inflow resistance is increased by the porous ceramic described above, there is an effect that the electrolysis efficiency can be increased within the limited capacity of the electrolytic cell and the space of the equipment. Further, the constant flow rate valve or filter provided in the outflow pipe of the generated ion water further increases the water flow resistance of the inflow water into the current tank, which has the effect of increasing the electrolysis efficiency.
