Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an ionic water generator that purifies raw water such as tap water and then adds a pH adjusting substance to generate ionic water.
[0002]
[Prior art]
In recent years, there has been a demand for safe, delicious and healthy water. As such water, water obtained by electrolyzing raw water such as tap water has attracted attention, and ionic water generators have begun to spread in ordinary homes and restaurants. When an ionic water generator is used, raw water can be electrolyzed to obtain ionic water such as alkaline water or acidic water. At that time, alkaline water has an antacid effect, a swelling effect, etc., so it is used for beverages or cooking, and acidic water has an astringent effect, etc., and is used as a lotion. In particular, strong acid water returns to normal water if left undisturbed for several days, so it does not pollute the environment and is suitable for washing water such as tea astringent drops.
[0003]
In general, an ionic water generator collects a water purifier, a pH adjusting substance addition tank, an electrolytic tank, each water pipe, a control circuit component including a microcomputer, a power circuit component including a power transformer, and the like in a case, The whole is downsized for easy handling. At the time of use, the water inlet of the ion water generator is connected to a tap and the like, and raw water such as tap water is fed. Then, first of all, the water can be purified by the water purifier. At that time, if the water purifier uses antibacterial activated carbon and hollow fiber membrane, for example, the activated carbon decomposes the odor-causing odor or musty odor and removes germs and the like with the hollow fiber membrane. Can do.
[0004]
Next, when purified water is fed into a pH adjusting substance addition tank, the calcium ion concentration of alkaline water is increased in the addition tank, for example, calcium lactate is dissolved in water and added, or the pH value of acidic water is decreased, for example, salt Can be added by dissolving in water. Therefore, when purified water, added water, or the like is fed into the electrolytic cell, alkaline water or acidic water can be obtained from the cathode chamber divided by a diaphragm and from the anode chamber, respectively. At that time, calcium lactate or the like for increasing the calcium ion concentration of alkaline water is added to the water entering the anode chamber of the electrolytic cell, and sodium chloride or the like for lowering the pH value of acidic water is added to the water entering the cathode chamber and the anode chamber, respectively. Even when a substance that increases the calcium ion concentration is added to water, the pH value of the produced water naturally changes.
[0005]
[Problems to be solved by the invention]
However, even if such an ionic water generator is used, the chlorine odor dissolves in water and reaches the electrolytic cell only by eliminating the odor of chalk. Therefore, chlorine gas is generated in the anode chamber by electrolysis. This chlorine gas tends to enter the cathode chamber through the diaphragm together with acidic water. Then, not only acidic water is mixed with alkaline water used for beverages and the like, but also alkaline water has a chlorine gas odor. Further, alkaline water generated in the cathode chamber easily passes through the diaphragm and enters the anode chamber, and since alkaline water is mixed with acidic water, there is a problem that it is difficult to obtain highly acidic water with high purity even if sodium chloride is added. Even if salt is added only to the water entering the anode chamber, it is difficult to increase the conductivity on the cathode chamber side, so that strongly acidic water cannot be obtained.
[0006]
The present invention has been made paying attention to such conventional problems. First, an ion equipped with a pH adjusting substance addition tank capable of generating highly pure water having a stable pH value and oxidation-reduction potential and having high purity. An object is to provide a water generator.
[0007]
Second , if weak alkaline water is required, use a substance that increases calcium ion concentration in the pH adjustment substance addition tank. If strong acidic water is required, use a substance that decreases pH value. Another object of the present invention is to provide an ionic water generator equipped with a pH adjusting substance addition tank that can easily exchange the pH adjusting substance.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, in the ionic water generator provided with the pH adjusting substance addition tank corresponding to the first object according to the present invention , the water supply main pipe for sending the purified water from the water purifier to the electrolytic cell is provided in the middle of the cathode of the electrolytic cell. The inflow pipe leading to the chamber and the inflow pipe leading to the anode chamber are divided into pipes, and the electrolytic cell is further provided with an outflow pipe exiting from the cathode chamber and an outflow pipe exiting from the anode chamber. A pH adjusting substance addition tank for adding a substance that lowers the pH value of water is provided.
[0011]
The amount of added water entering the anode chamber of the electrolytic cell is increased, the amount of added water entering the cathode chamber is decreased, the amount of alkaline water exiting from the cathode chamber is increased, the amount of acidic water exiting from the anode chamber is decreased, The flow rate ratio of the amount of added water entering the chamber is made larger than the flow rate ratio of alkaline water and acidic water exiting from each of the yin and yang electrode chambers. For this purpose, the anode channel inflow tube is made thicker than the cathode chamber inflow tube by providing an orifice with a small diameter in the cathode chamber inflow tube, and the cathode chamber inflow tube is further connected to the anode chamber outflow tube. What is necessary is just to make the water channel of a cathode chamber outflow pipe thicker than the water channel of an anode chamber outflow pipe by providing an orifice with a diameter larger than the orifice provided in this water channel.
[0012]
Further, the ion water generator having a pH adjusting agent addition tank of the second object corresponding to the inlet pipe and anode chamber leading to the cathode compartment of the electrolytic cell the water passing mains to send water purification to the electrolytic cell from the water purifier in the middle Branch to the inflow pipe to reach the inflow pipe. In addition, an outflow pipe from the cathode chamber and an outflow pipe from the anode chamber are provided in the electrolytic cell, and a substance that adjusts the pH value of the purified water is added to the inflow pipe. A pH adjusting substance addition tank is provided.
[0013]
Then, one end constituting the pH adjusting substance adding tank is closed, and the other end is closed with an openable / closable cap, and the water main, the cathode chamber inflow tube, the anode chamber inflow tube, or the both chambers inflow tube Are provided with two inflow pipes that function as any of the above, the internal space of each pipe communicates with the internal space of the outer cylinder, and the water main pipe and one inflow pipe are coupled by a communication pipe The water passage of the anode chamber outflow pipe is made narrower than the water passage of the cathode chamber outflow pipe, and the water passage of the anode chamber outflow pipe is made narrower than the water passage of the cathode chamber outflow pipe. Then, the rate of thinning them is increased on the inflow pipe side and decreased on the outflow pipe side.
[0014]
In addition, when alkaline water is required, the outer cylinder has a water passage opening for immersing the stored substance that increases the calcium ion concentration, and the alkaline water pH that closes the internal opening of the water main when the cap is closed. A medium cylinder for adjusting substance storage and replacement is inserted and used as an alkaline water pH adjustment substance addition tank unit. When acid water is required, the outer cylinder has a water passage port for immersing the substance that lowers the stored pH value. Then, an acidic water pH adjusting substance housing / replacement inner cylinder for closing the communication pipe when the cap is closed is inserted and used as an acidic water pH adjusting substance adding tank unit.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a partial cross-sectional view showing a main part of an alkaline water pH adjusting substance addition tank unit provided in an ionic water generator to which the present invention is applied. In the figure, 10 is an alkaline water pH adjusting substance adding tank unit, 12 is an alkaline water pH adjusting substance adding tank of the unit 10, 14 is a water main that sends purified water from a water purifier (not shown) to an electrolytic tank, 16 is An inflow pipe for adjusting the flow rate ratio of the water to be sent to the cathode chamber and the anode chamber of the electrolytic cell by dividing the purified water flowing through the water flow main pipe, and 18 is a communication between the water flow main pipe and the flow rate adjusting inflow pipe 16. This is a communication pipe. The addition tank 12 includes two inflow pipes including the inflow pipe 16.
[0016]
The alkaline water pH adjusting substance addition tank 12 has an outer cylinder 20 with the lower end closed and the upper end opened, and an inner cylinder 22 for storing and replacing an alkaline water pH adjusting substance with the lower end closed and the upper end opened. And an openable and closable cap 24 that closes the upper ends of the inner and outer cylinders 20 and 22. The outer cylinder 20 is connected to the ends of the water main pipe 14 and the two inflow pipes 16, and the inner space of the outer cylinder 20 is communicated with the inner space of the pipes 14, 16. . At that time, the water main pipe 14 is installed so that its upper end protrudes slightly inward from the center of the bottom wall of the outer cylinder 20, and each inflow pipe 16 etc. has its upper end opening at the lower end side wall of the outer cylinder 20. It is arranged so as to communicate with the internal space expansion portions 26 (26a, 26b) provided at two locations by partially protruding outward. In addition, the outer cylinder 20 has an oblique groove whose upper end is opened into the symmetrical position of the inner wall of the upper end of the outer cylinder 20 while the cap 28 is pushed in while closing and the protrusions 28 (28a, 28b) at the symmetrical position of the upper side wall are fitted respectively. 30 (30a, 30b) are provided.
[0017]
Further, the middle cylinder 22 has a bottom wall 32 protruding inwardly in a truncated cone shape, and water passages 34 are equally disposed at several places, for example, six places on the lower end side wall. Then, each water passage 34 is closed with a net 36. Further, the middle cylinder 22 is provided with a projection 38 (38a, 38b) for connection with the cap 24 at a symmetrical position on the outer surface of the side wall at the upper end. Therefore, the lower side wall of the cap 24 is provided with an elongated L-shaped through-hole 40 (40a, 40b) having a lower end that is fitted with the cap 24 on the upper end portion of the middle cylinder 22 and is opened while being rotated. The cap 24 is further provided with a knob 42 at the top, and a sealing O-ring 44 is fitted in the center of the outer surface of the side wall.
[0018]
The middle cylinder 22 may be closed only by the cap 24. However, in order to increase the sealing degree of the middle cylinder 22 and increase the connection strength between the cap 24 and the middle cylinder 22, the middle cylinder 22 is used by being pushed into the upper end portion of the middle cylinder 22. Use a lid (not shown). Therefore, the main body of the inner lid is a cylindrical body with the lower end closed and the upper end opened, and a knob projection is provided upward from the center of the bottom wall. Further, in order to prevent the inner lid from falling into the inner cylinder 22, a collar portion that covers the upper edge of the inner cylinder 22 is provided on the upper edge of the cylindrical body. Reference numeral 46 denotes a metal sensor for detecting a stainless steel ring provided in an acidic water pH adjusting substance housing replacement cylinder described later.
[0019]
The flow rate adjusting inflow pipe 16 is provided near the inlet of the water channel of a part 48 that connects the outer cylinder 20 and the communication pipe 18 in order to adjust the flow ratio of water sent to the cathode chamber and the anode chamber of the electrolytic cell. An orifice 50 is provided. Therefore, when the purified water sent to the water main pipe 14 enters the inflow pipe 16 through the communication pipe 18, a part of the water passes through the alkaline water pH adjusting substance addition tank 12 and passes through the anode of the electrolytic cell. Go to the chamber and most of the water goes to the cathode chamber.
[0020]
At the time of use, first, for example, several calcium lactate tablets are placed in the inner cylinder 22 as an adjusting substance for increasing the calcium ion concentration of alkaline water. Then, the inner lid is put on and the cap 24 is put on to connect the cap 24 and the inner cylinder 22. Next, they are put in the outer cylinder 20, the cap 24 is tightened, and the outer cylinder 20 is closed. Then, the bottom wall 32 of the middle cylinder 24 is pressed against the bottom wall 54 of the outer cylinder 20 so as to cover the inner opening 52 of the water main pipe 14, and water flows into the addition tank 12 from the water main pipe 14. Can be cut off.
[0021]
For this reason, when raw water such as tap water is purified by a water purifier and then fed into the water main pipe 14, the purified water flows as shown by the arrows in FIG. Most of the purified water passes through the inflow pipe 16 as it is and flows into the cathode chamber of the electrolytic cell, but a part of the purified water that has passed through the orifice 50 passes through a part 48 of the inflow pipe 16 and enters the addition tank 12. Then, the calcium lactate tablet 56 is soaked and added water in which it is dissolved, and enters the anode chamber through another inflow pipe 58. When the orifice 50 or the like is provided in this way, the water channel of a part 48 connecting the outer tube 20 of the inflow pipe 16 for adjusting the flow rate ratio and the communication pipe 18 is made narrower than the water channel of the other part 60 connected to the connection pipe 18, The flow rate ratio can be considerably increased by increasing the amount of purified water entering and decreasing the amount of added water entering the anode chamber. At that time, it is preferable to set the flow rate ratio between the purified water amount and the added water amount to 8: 1.
[0022]
Such an electrolytic cell containing purified water and added water has a structure as shown in FIG. In the figure, 62 is an electrolytic cell, 64 is a cathode chamber thereof, 66 is an anode chamber, 68 is a diaphragm partitioning both chambers 64 and 66, 70 is a cathode, and 72 is an anode. In addition, 74 is an inflow pipe connected to the inflow pipe 16 of the addition tank unit 10, 76 is an inflow pipe connected to the inflow pipe 58, 78 is an outflow pipe for sending out alkaline water, 80 is an outflow pipe for sending out acid water, and 82 is It is an orifice provided near the inlet of the water channel of the outflow pipe 80. When the orifice 82 or the like is provided in this way, the flow path of the outflow pipe 80 is made narrower than the flow path of the outflow pipe 78, the amount of alkaline water coming out of the cathode chamber 64 is increased, and the amount of acidic water coming out of the anode chamber 66 is reduced. Can be made smaller than the flow ratio of the purified water and the added water entering the two chambers 64 and 66, respectively. At that time, it is preferable to set the flow ratio of alkaline water and acidic water to 3: 1.
[0023]
In this way, the amount of purified water entering the cathode chamber 64 of the electrolytic cell 62 is increased, the amount of added water entering the anode chamber 66 is decreased, the amount of alkaline water exiting from the cathode chamber 64 is increased, and the amount of acidic water exiting from the anode chamber 66 is decreased. Then, if the flow rate ratio of the purified water entering the Yin / Yang polar chambers 64 and 66 and the amount of added water is larger than the flow rate ratio of alkaline water and acidic water coming out of the Yin / Yang polar chambers 64 and 66, the purified water entering the cathode chamber 64. The amount of alkaline water coming out of the chamber 64 is small, the amount of added water entering the anode chamber 66 is small, and the amount of acidic water coming out of the chamber 66 is large. For this reason, chlorine ions dissolved in purified water or added water and flowing into the electrolytic cell 62 are negative ions, so that chlorine gas is generated in the anode chamber 66 by electrolysis, and the chlorine gas enters the cathode chamber 64. Even so, the flow of alkaline water that flows from the cathode chamber 64 through the diaphragm 68 to the anode chamber 66 and flows out from the outflow pipe 80 is hindered, and chlorine gas is sent out from the outflow pipe 80 together with acidic water and the like. Therefore, the alkaline water that exits from the outflow pipe 78 of the cathode chamber 64 is unlikely to contain chlorine gas, and acid water is also unlikely to be mixed.
[0024]
The calcium lactate dissolved in the added water and flowing into the electrolytic cell 62 is separated into lactate ions and calcium ions, and the calcium ions reach the cathode chamber 64 because they are positive ions. Therefore, when calcium lactate is added to water, the calcium ion concentration and pH value of alkaline water can be increased and stabilized. However, in reality, if a large amount of calcium lactate is added, it will adhere to the diaphragm 68 and cause inconvenience. Therefore, when calcium salt (calcium hydrogen carbonate, calcium sulfate, etc.) contained in the raw water is small, it is added as an electrolysis aid. You should do it. In addition, if acidic water is prevented from being mixed with the alkaline water exiting from the outflow pipe 78 of the cathode chamber 64 in this way, the oxidation-reduction potential (ORP) of the alkaline water is stably about -50 mV. As it becomes weak alkaline water most suitable for the body. Note that a variable voltage of 0 to 40 V is applied to the electrolytic cell 62, but naturally the higher the voltage value, the higher the pH value.
[0025]
FIG. 4 is a partial cross-sectional view showing a main part of an acidic water pH adjusting substance addition tank unit provided in an ionic water generator to which the present invention is applied. When the acidic water pH adjusting substance adding tank unit 84 is compared with the alkaline water pH adjusting substance adding tank unit 10 described above, the acidic water pH adjusting substance storage exchange is replaced with the alkaline water pH adjusting substance storage inner cylinder 22. The point which comprises the acidic water pH adjustment substance addition tank 88 using the middle cylinder 86 differs. Further, the use of the acidic water pH adjusting substance housing replacement cylinder 86 makes the water channel configuration different. However, since the other unit configurations are the same, the same reference numerals are used for the same corresponding parts as necessary.
[0026]
The middle cylinder 86 also has a cylindrical body with the lower end closed and the upper end opened, and the bottom wall 90 projects inward in a truncated cone shape. And the communication pipe 18 is closed in the center of the bottom wall 90, the protrusion pipe | tube 92 for guide | inducing the water of the water main pipe 14 in internal space is provided, and the water passage port 94 is provided in several places, for example, four places in the lower end side wall. Distribute evenly. Further, the position corresponding to the ceiling of the water passage space portion 96 is closed and formed on the bottom wall 98 of the space portion for storing a substance that lowers the pH value, for example, salt, and there are several places such as the center and the left and right 3 A small hole for entering and exiting a small amount of water is provided at the location. Further, a belt-shaped stainless ring 100 is wound and mounted on the outer surface of the central side wall, and connection projections 102 (102a, 102b) for connection with the cap 24 are provided at symmetrical positions on the outer surface of the upper end side wall. An inner lid is also used for the acidic water pH adjusting substance accommodating / replacement inner cylinder 86, but the inner lid is also used as the lid for the alkaline water adjusting substance accommodating / replacement inner cylinder 22.
[0027]
At the time of use, salt is first put in the pH adjusting substance storage space of the middle cylinder 86. Similarly, the inner lid is put on and the cap 24 is fitted, and the cap 24 and the middle cylinder 86 are connected. Further, they are put in the outer cylinder 20 and the cap 24 is tightened to close the outer cylinder 20. Then, the protruding pipe 92 provided on the bottom wall 90 of the middle cylinder 84 is inserted into the water main pipe 14 so that the inflow of water into the communication pipe 18 can be blocked.
[0028]
For this reason, when purified water is fed into the water main 14, the water flows as shown by the arrow in FIG. 5, and first of the water passage space 96 of the middle cylinder 86 constituting the acidic water pH adjusting substance addition tank 88. go inside. Then, it enters into the pH adjusting substance storage space 106 through each small hole 104 provided in the bottom wall 98, and becomes the added water in which the salt 108 is soaked and dissolved little by little. Then, the flow is divided inside the intermediate cylinder 86, and the orifice 50 is provided in the inflow pipe 16 as shown in FIG. 6, so that most of the added water passes through the inflow pipe 58 and the anode chamber 66 of the electrolytic cell 62. However, a part of the added water flows into the cathode chamber 64 through the inflow pipe 16. Therefore, the flow rate ratio of the additive water entering the anode chamber 66 and the cathode chamber 64 is considerably increased. For example, 8 to 1 is preferable.
[0029]
Then, alkaline water and acidic water are generated in the electrolytic cell 62 and sent out from the outflow pipes 78 and 80, respectively. Since the outflow pipe 80 is provided with the orifice 82, the amount of alkaline water coming out from the cathode chamber 64 is increased, and the anode The amount of acidic water coming out of the chamber 66 can be reduced. In that case, it is preferable to make the flow rate ratio of alkaline water and acidic water into 3: 1, for example. In this way, the amount of added water entering the anode chamber 66 is increased, the amount of added water entering the cathode chamber 64 is decreased, the amount of alkaline water exiting from the cathode chamber 64 is increased, and the amount of acidic water exiting from the anode chamber 66 is decreased. When the flow rate ratio of the added water amount entering each of the positive and negative electrode chambers 66, 64 is larger than the flow rate ratio of alkaline water and acidic water exiting from each of the positive and negative electrode chambers 64, 66, the added water amount entering the anode chamber 66 increases. The amount of acidic water exiting from 66 decreases, the amount of added water entering the cathode chamber 64 decreases, and the amount of alkaline water exiting from the chamber 64 increases.
[0030]
For this reason, this time, acidic water flows from the anode chamber 66 through the diaphragm 68 to the cathode chamber 64 and flows out from the outflow pipe 78. Therefore, it is difficult for alkaline water to be mixed with the acidic water from the outflow pipe 80 of the anode chamber 66, and the concentration of the added water entering each chamber 64, 66 is equal and the conductivity in the tank is uniform, so that the electrolysis can proceed easily. Thus, highly acidic water with high purity is obtained. At that time, hydrochloric acid water and hydrogen peroxide water are formed in the cathode chamber 66 as acidic water, and sodium hydroxide water is formed in the anode chamber 64. However, sodium hydroxide water is mixed in alkaline water, so that the cathode chamber 64 flows out. Feed out from tube 78. In this way, when salt is added to water, the pH value of acidic water can be stabilized at about 2.5, and since alkaline water is not mixed, the oxidation-reduction potential of acidic water can be stabilized at +1100 mV or more. . Moreover, since a large amount of chlorine gas is generated in the anode chamber 66, the chlorine concentration of the acidic water becomes about 30 ppm. Therefore, it becomes suitable as water for washing such as tea dripping. In addition, the acidic water obtained with the conventional ionic water generator has a pH value of about 4.
[0031]
Naturally, the alkaline water sent out from the outflow pipe 78 is strong alkaline water, and a large amount of chlorine gas is contained therein. Therefore, it must be ensured that such alkaline water is not accidentally used for beverages. Therefore, the operation mode of the ionic water generator is made different between the case where weak alkaline water suitable for ordinary beverages is required and the case where strongly acidic water as sanitary water is required. Then, when the acidic water pH adjusting substance storage and replacement inner cylinder 86 is put in the outer cylinder 20, the stainless steel ring 100 is detected by the metal sensor 46, and the normal mode is switched to the strongly acidic water mode. Then, for example, the motor-type spool valve is driven to switch the water channel so that water is not released from the outlet from which the weak alkaline water is released in the normal mode in the strong acid water mode, and a large amount of chlorine gas or water is discharged from the other outlets. Strong alkaline water containing sodium oxide can be released. Therefore, strong alkaline water containing a large amount of chlorine gas or the like is not erroneously provided for beverages.
[0032]
In the above embodiment, a stainless steel ring is used as a member for identification in the acidic water pH adjusting substance storage replacement cylinder, and a metal sensor is installed in the outer cylinder. A sensor corresponding to the identification member may be used. Naturally, the identification member may be installed on the inner cylinder for storing and replacing the alkaline water pH adjusting substance.
[0033]
In the above embodiment, a substance that increases the calcium ion concentration is added to generate a large amount of weak alkaline water. However, when a large amount of weak acidic water is required, the polarities of both electrodes may be reversed.
[0035]
【The invention's effect】
According to the present invention described above, in the invention of claim 1, wherein the addition of substances which lower the pH value of the acidic water in the water entering the cathode and anode chamber, flows from the anode chamber to the cathode chamber, outflow provided to the cathode chamber Since the acidic water flowing out from the pipe is generated and the chlorine gas is generated in the anode chamber, the required acidic water is likely to contain chlorine gas and the alkaline water is hardly mixed. Therefore, it is possible to obtain highly acidic water with high purity which is stabilized by lowering the pH value. Moreover, the oxidation-reduction potential can be set to a stable value suitable for sanitary water.
[0036]
Further, in the same external cylinder constituting the pH adjusting agent addition tank at the second aspect of the present invention, using put cylindrical in accommodating the calcium ion concentration rises substance if necessary weakly alkaline water, strong acids When alkaline water is required, a weakly alkaline water and sanitary water suitable for beverages can be used by simply inserting the inner cylinder containing the pH-decreasing substance. As a result, it is possible to obtain a strong acidic water suitable as
