The water purification cartridge 22 functions as a pre-filter, and filters out elements that cannot be electrolyzed by the electrolytic cell unit 25 such as free residual chlorine and lead contained in tap water. The water purification cartridge 22 is a cartridge system that can be replaced with a single touch when the function is reduced, thereby improving handling. In the water purification cartridge 22, for example, a carbon filter containing activated carbon (carbon) and a mineral filter containing mineral ceramic or natural ore for adding minerals to water are stored. The carbon filter has a cylindrical shape with a predetermined thickness, and a columnar mineral filter is disposed in the hollow portion.

If the cartridge replacement lamp 106 is lit, it is time to replace the water purification cartridge 22 and the water discharge cartridge 26. To replace the water purification cartridge 22, the power plug 35 (see FIG. 8) described later is removed, the power is turned off, and the work is started after the water tap is closed. First, as shown in FIG. 9, the water purification cartridge cover 12 is opened, the water purification cartridge holder 221 is turned in the direction of the circled numeral 1, the water purification cartridge holder 221 is removed in the direction of the circled numeral 2, and the water purification cartridge 22 is removed.

The check valve 23 is a valve for preventing a back flow of water from the electrolytic cell unit 25. By providing the check valve 23 between the water purification cartridge 22 and the electrolytic cell unit 25, it is possible to prevent a large amount of water from flowing backward from the electrolytic cell unit 25 when the water purification cartridge 22 is replaced. Thereby, the water of the electrolytic cell unit 25 does not overflow when the water purification cartridge 22 is replaced.

The flow sensor 24 detects the amount of flowing water flowing into the electrolytic cell unit 25 and generates a constant pulse with respect to the determined amount of flowing water. The flow sensor 24 is a base for various controls such as reduction start / reduction stop control, reduction time control, and cartridge life management.

12 and 13 are a longitudinal sectional view and a horizontal sectional view of the electrolytic cell unit 25, respectively. The electrolytic cell unit 25 is a unit that electrolyzes water and lowers the oxidation-reduction potential to generate reduced hydrogen water. The electrolytic cell unit 25 is composed of three parallel electrodes and the electrolytic cell so as to enclose the electrode unit 251. The main part is comprised from the electrolytic cell bin 252 to form, and the electrolytic cell base 253 which fixes the lower part of the electrode unit 251 and the electrolytic cell bin 252.

In the electrode unit 251, the third electrode is arranged in the center, and the first and second electrodes are arranged on both sides so as to face each other at equal intervals. In the reduction (electrolysis), as disclosed in Patent Document 1, Patent Document 2, and Patent Document 3, high-frequency alternating current (30 KHz to 50 KHz) is generated between the first electrode and the second electrode. A voltage (10 V to 50 V) is applied, the third electrode is grounded, a direct current is passed through the water from the first electrode and the second electrode to the third electrode, the water is electrolyzed, and the water is electrolyzed. Reduce the redox potential to make reduced hydrogen water.

As a material for each electrode of the electrode unit 251, metals such as magnesium, aluminum, lithium, zinc, magnesium, iron, stainless steel, and copper can be used. However, platinum formed on a rectangular net is subjected to platinum plating. It is preferable to use the above. When such a material is used, titanium is excellent in corrosion resistance and durability, and platinum cannot form an oxide film on the surface, so the reaction of water electrolysis is stabilized and the reaction is performed efficiently. Maintenance is not required because it does not dissolve in water. In particular, the electrode is made into a mesh body, because electrolysis is performed while water moves in the electrolytic cell bottle 252, so that the movement time of water, that is, the reduction time can be secured by enlarging the electrode in a mesh shape. Because it can. In principle, the electrolysis reaction (decrease in redox potential) is proportional to the area of the electrode. However, when the electrode is a net, the redox potential is lower than that of a plate electrode having the same surface area. Good results are obtained with a large reduction.

The electrolytic cell bin 252 is formed of a transparent tempered glass and has a cylindrical shape with an opening at the lower end. Calcium and the like are deposited on the electrode unit 251 (particularly, the electrode of Measure 3) and adhere to the upper end of the electrolytic cell bottle 252 by electrolysis of water, so that the screw can be washed away with a cleaning liquid (for example, vinegar) from the outside. A narrow-mouth cleaning liquid inlet 252a having a built-in cap is provided. The screw-in type cap is opened, and the cleaning liquid is supplied to the electrolytic cell bottle 252 from the cleaning liquid inlet 252a. Since the electrolytic cell bottle 252 is made of transparent glass and the reduction confirmation window 17 is provided in the apparatus main body as described above, the reduced state of water can be easily confirmed from the outside by bubbles or the like, and the electrolytic cell unit 25 is contaminated. Etc. can be easily confirmed.

The electrolytic cell base 253 is formed in a disc shape from a synthetic resin, and has a water inlet channel 235a and a water outlet channel 235b, and ribs (walls) 253c are substantially 3 / long along the inner peripheral surface of the electrolytic cell bottle 252. It is formed to make four rounds. Further, an electrode collar 254 protrudes from the center of the upper surface of the electrolytic cell base 253, and the lower ends of the three electrodes of the electrode unit 251 are attached. Further, a rectifying plate 255 made of a flexible ring-shaped plate body is disposed with its vertical direction defined so as to be sandwiched between the electrolytic cell base 253 and the electrode collar 254. The electrolytic cell base 253 is watertightly fitted through a lower end opening of the electrolytic cell bottle 252 and an O-ring with a stopper (not shown) to form an electrolytic cell. In addition, since calcium or the like is deposited and adhered to the electrode unit 251 (particularly, the electrode of Measure 3) by electrolysis of water on the lower surface portion of the electrolytic cell base 253, a screw-in type is used so that this can be washed away with a cleaning liquid from the outside. A waste liquid port 253d having a cap is provided.

When the amount of water increases, as shown by a broken line in FIG. 12, the rectifying plate 255 slightly lifts the peripheral edge so that water flows out uniformly from the gap between the rectifying plate 255 and the electrolytic cell base 253 toward the outside. ing. That is, this gap has a structure in which the interval can be changed according to the amount of water. In addition, the amount of water flowing from the outer periphery increases and the amount of water also increases from the center hole, so that generally uniform water flows upward from below, so that unelectrolyzed water does not go out to the outlet channel 253b as it is. . Further, in the electrolytic cell unit 25, water is once sent from the lower part of the electrolytic cell bottle 252 to the upper part of the electrolytic cell bottle 252, and the water is directed from the upper part to the lower part of each electrode of the electrode unit 251, so that the electrolytic reaction is performed. The reduction time is secured. As described above, by adopting a structure in which the water flowing into the electrolytic cell unit 25 does not move all at once and moves gradually and uniformly as much as possible, consideration is given so that the numerical values such as the oxidation-reduction potential do not vary.

As described above, since the electrolytic cell unit 25 is arranged with the electrolytic cell base 253 facing down, the electrolytic cell base 253 has a water inlet 253a, a water outlet 253b, a rib (wall) 253c, a waste liquid port 253d, and an electrode. The electrodes of the collar 254, the rectifying plate 255 and the electrode unit 251 can be arranged together, and the electrolytic cell base 253 can be easily attached to the lower end opening of the electrolytic cell bottle 252. With such a configuration, there is an advantage that the electrolytic cell unit 25 can be easily disassembled and assembled.

The water discharge cartridge 26 is detachably loaded downstream of the electrolytic cell unit 25 inside the apparatus main body. The water discharge cartridge 26 includes an activated carbon filter, a dechlorinating agent, and the like, and removes free chlorine generated by electrolysis in the electrolytic cell unit 25.

As described above, when the cartridge replacement lamp 106 is turned on, it is time to replace the water purification cartridge 22 and the water discharge cartridge 26. In order to replace the water discharge cartridge 26, as in the case of replacing the water purification cartridge 22, the power plug 35 (see FIG. 8) is removed, the power is turned off, and the work is started after the water tap is closed. First, as shown in FIG. 14, the water discharge cartridge cap 16 on the apparatus main body is opened by turning in the direction indicated by the circled numeral 1, and the water discharge cartridge 26 is pulled out in the direction indicated by the arrow 2. Next, a new water discharge cartridge 26 is inserted into the water discharge cartridge case 1b in the direction opposite to the circled number 2 arrow, and the water discharge cartridge cap 16 is turned in the direction opposite to the circled number 1 arrow and closed.

FIG. 8 is a block diagram showing the configuration of the electrical system of the reduced hydrogen water generator 1.

Note that a control circuit centered on a CPU (not shown) is mounted on the control board 30, and a CPU built-in timer (not shown; hereinafter simply referred to as a timer) has a reduction time and a reduction interruption or after termination. Count the elapsed time. The details of the control board 30 are not directly related to the present invention, and will not be described.

High frequency alternating current and direct current necessary for reduction (electrolysis) are supplied from the control substrate 30 to each electrode of the electrode unit 251 of the electrolytic cell unit 25. Further, from the flow sensor 24, a pulse is notified to the control board 30 via a signal line for every fixed amount of flowing water. The control board 30 counts the pulses from the flow sensor 24, and when the accumulated water flow exceeds a predetermined amount, the cartridge replacement lamp 106 (cartridge replacement LED 336) is turned on to replace the water purification cartridge 22 and the water discharge cartridge 26. Inform the time.

The switch board 31 is provided with a rotary switch 311 that can be set from the outside. The rotary switch 311 is provided so that the user can adjust the basic reduction time and the reverse voltage application pattern that prevents the adhesion of calcium according to the water quality or the like for each region or season in which the reduced hydrogen water generator 1 is used. .

On the illumination board 32, an LED (Light Emitting Diode) 321 for illuminating the electrolytic cell unit 25 visible from the reduction confirmation window 17 in the reduction mode is disposed.

On the display board 33, an ON / OFF key switch 331 corresponding to the ON / OFF button 101 of the operation panel 10, an ON / OFF (power) LED 332 corresponding to the power lamp 102, and a reduction corresponding to the reduction / water purification button 103 are displayed. / Water purification key switch 333, reduction LED 334 corresponding to the reduction lamp 104, water purification LED 335 corresponding to the water purification lamp 105, cartridge replacement LED 336 corresponding to the cartridge replacement lamp 106, and reset key switch 337 corresponding to the reset button 107 Is provided.

After the water purification cartridge 22 and the water discharge cartridge 26 are replaced, when the reset button 107 (reset key switch 337) is pressed, the cartridge replacement lamp 106 (cartridge replacement LED 336) is turned off, and the running water accumulated by the control board 30 is also added. The amount (flowing water amount counter) is returned to the initial value.

When the ON / OFF button 101 (ON / OFF key switch 331) is pressed, the power supply is turned off and the power lamp 102 (ON / OFF (power supply) LED 332) is turned on. At this time, in the reduction mode, the reduction lamp 104 (reduction LED 334) is also turned on.

In the reduction mode, the water purification mode in which only the water purification cartridge 22 is used when the reduction / water purification button 103 (reduction / water purification key switch 333) is pressed. At this time, the reduction lamp 104 (reduction LED 334) is turned off, and the water purification lamp 105 (water purification LED 335) is turned on instead.

Next, operation | movement of the reducing hydrogen water production | generation apparatus 1 which concerns on 1st Embodiment comprised in this way is demonstrated.

The reduced hydrogen water generator 1 is used by being directly connected to a water tap. A faucet faucet adapter 2 (see FIG. 7) is connected to a water faucet, and a water supply hose 4 such as an elastomer hose is connected thereto, and this end is attached to the water supply elbow 11 of the reduced hydrogen water generator 1. When passing water, a switching lever (not shown) provided in the faucet faucet adapter 2 is operated to switch the tap water flow path to the reduced hydrogen water generator 1.

When the reduced hydrogen water generator 1 is in operation, the power is turned on by pressing the ON / OFF button 101 (ON / OFF key switch 331), and the reduction / purified button 103 (reduction / purified key switch 333) is turned on. When in the reduction mode by pressing, the tap faucet adapter 2 is operated to allow tap water to flow into the reduced hydrogen water generator 1, and the constant flow valve 21 is operated as necessary to adjust the amount of water. Detects the flowing water, the control board 30 recognizes this, supplies high frequency alternating current and direct current to the electrolytic cell unit 25, and starts reduction (electrolysis). Or, even if there is no inflow of water, after one minute or more has passed since the end of the previous reduction, when the power is on, the reduction / purification button 103 (reduction / purification key switch 333) is pressed to switch from the purified water mode to the reduction mode, When switching from the power OFF state to the power ON state by pressing the ON / OFF button 101 (ON / OFF key switch 331) in the return mode, the control board 30 confirms the elapsed time after the previous return interruption or end, Reduction (electrolysis) is started by supplying high-frequency alternating current and direct current to the electrolytic cell unit 25. Note that after the main power is turned on, the first reduction operation is performed in the basic reduction time even if there is no inflow of water.

The tap water flowing from the feed elbow 11 of the reduced hydrogen water generator 1 moves from the outer peripheral side of the carbon filter in the water purification cartridge 22 to the inner peripheral side, and further, the water is converted into a mineral filter on the inner peripheral side of the carbon filter. It penetrates and mineral components are added and sent out as purified water.

The purified water sent from the purified water cartridge 22 passes through the flow sensor 24 via the check valve 23. As a result, a pulse is output from the flow sensor 24 to the control board 30 for each constant amount of flowing water.

In the control board 30, the pulse input is connected to an event interruption of the CPU, and the CPU counts up the water flow counter because an interruption occurs every time a pulse occurs.

Further, the purified water flows into the electrolytic cell base 253 from the water inlet 253 a, and the inflowed water moves around the outer periphery of the electrolytic cell base 253 along the ribs (walls) 253 c provided on the electrolytic cell base 253 and the rectifying plate 255. It flows into the electrolytic cell bottle 252 uniformly from the slight gap between the outer wall and the current plate 255 over the entire outer periphery. The main flow of the incoming water will eventually reduce the flow rate, decelerate and flow out of the center hole. The water that has flowed into the electrolytic cell bottle 252 passes between the three electrodes of the electrode unit 251 and is electrolyzed, and the generated reduced hydrogen water is sent out from the water discharge channel 253b of the electrolytic cell base 253 toward the water discharge cartridge 26. .

The water discharge cartridge 26 removes free chlorine generated by electrolysis from the reduced hydrogen water and sends it to the water discharge cap 13.

The reduced hydrogen water that has passed through the spout cap 13 is discharged from the spout pipe 14 in the direction and position desired by the user.

According to the reduced hydrogen water generating apparatus 1 according to the present embodiment, chlorine, lead, etc. are removed and minerals are added in the water purification cartridge 22, whereby electrolysis is performed in the electrolytic cell unit 25 with water containing minerals. The reaction is promoted, and reduced hydrogen water having a greatly reduced redox potential is obtained. Thus, in the electrolytic cell unit 25, high-frequency alternating current and direct current are applied to water to generate a large amount of active hydrogen, and reduced hydrogen water having high electronic energy and containing minerals in a well-balanced manner is generated. This reduced hydrogen water has high osmotic pressure, is easily absorbed by the body, and stimulates cells and organs to activate metabolism.

In addition, according to the reduced hydrogen water generator 1 according to the present embodiment, by adopting electrolysis using high frequency alternating current and direct current, the molecular group (cluster) of water becomes small, and delicious reduced hydrogen water that is easily absorbed by the body. Is generated. In addition, the reduced hydrogen water contains a large amount of dissolved oxygen that plays an important role in the resuscitation of organisms. Normally, harmful active oxygen in the living body is in a state of a very high redox potential of 800 mV, but mineral-reduced hydrogen water is oxidized by generating reduced hydrogen having a low redox potential (−42 mV). It reduces and neutralizes the cells and tissues in the body and binds active hydrogen to harmful active oxygen to make it harmless.

Next, the operation of the reduced hydrogen water generator 1 according to the first embodiment will be described in more detail with a focus on control on the control board 30.

FIG. 15 is a diagram showing an example of the contents of the rotary switch table 36 stored in a ROM (Read Only Memory) (not shown) on the control board 30. The rotary switch table 36 is a table representing the relationship between the set value (SW number) of the rotary switch 311, the basic reduction time, and the reverse voltage application pattern. The basic reduction time is obtained in advance by experiments so that an optimal reduction time can be obtained according to the environment such as water quality. The reverse voltage application pattern is obtained in advance by experiments so as to prevent calcium adhesion depending on the environment such as water quality. Switching of the basic reduction time and reverse voltage application pattern by the setting of the rotary switch 311 (user) includes (1) basic reduction time (10 minutes ± t), and (2) reverse voltage for preventing calcium adhesion to the electrode. This is because optimum reduction control is performed by selecting the setting corresponding to the environment such as the water quality of the application time and period.

FIG. 16 is a diagram showing an example of the contents of a two-dimensional time correction table 37 stored in a ROM (not shown) on the control board 30. The reduction time correction amount (%) in the two-dimensional time correction table 37 is obtained in advance by experiments so that an optimum value is obtained according to the amount of flowing water and the elapsed time after the interruption or end of reduction. The reduction time correction amount by the elapsed time after the reduction interruption or termination is monitored by monitoring the elapsed time after the reduction interruption or termination, and the next reduction time is lengthened to compensate for the redox potential that is gradually lost with the elapsed time. Set. When the reduction is started by running water, the reduction time is corrected after waiting for the running water to stop.

It consists of. The timer interrupt routine is executed with an interrupt at a constant basic time (several ms) interval by a reload timer.

FIG. 20 is a flowchart showing a reduction end processing subroutine called in the timer interrupt routine shown in FIG. The processing of the reduction end processing subroutine includes a running water counter initialization step S401, an elapsed time counter initialization step S402, and a reduction stop step S403.

FIG. 21 is a flowchart showing a flow sensor interrupt routine. The process of the flow sensor interrupt routine includes a running water stop time counter initialization step S501 and a running water count step S502. In the flow rate sensor interrupt routine, a pulse input from the flow rate sensor 24 is connected to an event interrupt of the CPU, an interrupt is generated every time a pulse is generated, and the water flow counter is counted up.

The flowing water counter described in the flowchart is a counter that counts the pulses generated by the flow rate sensor 24, the elapsed time counter is a counter that counts the elapsed time since the interruption of the reduction or ends, and the reduction time counter is a counter that counts the reduction time. The running water stop time counter is a counter that counts the running water stop time. The running water stop time counter is initialized by an interruption from the flow sensor 24, and is counted down by a timer interruption, and if a specified time has elapsed (the counter overflows), it is determined that running water has stopped. Since running water is frequently initialized by interruption from the flow sensor 24, the count value of the running water stop time counter does not overflow. The flag F is a flag that is set when there is running water in the reduction mode and reset after the running water is stopped. For each counter for time management, each processing time is obtained by basic time × count value.

The conditions for starting the reduction are (1) water purification mode / reduction mode switching by the reduction / water purification button 103 when the ON / OFF button 101 is set to the ON state of the software power switch, and (2) running water in the reduction mode. There are two types. Specifically, if (1) there is a switch from the water purification mode to the reduction mode, or (2) there is running water at the time of standby after the interruption or termination of the reduction in the reduction mode, the reduction operation is started and the running time is reduced. Set the reduction time after stopping running water without setting.

When the software power switch is turned on by pressing the ON / OFF button 101, the main routine first initializes the system, such as initialization of the work area (step S101). Next, the soft power switch is turned off (step S102), the operation mode is set to the water purification mode (step S103), and after waiting for an interrupt, the key input is waited.

If the ON / OFF button 101 is pressed (YES in step S104), the soft power switch is switched from the OFF state to the ON state (step S105), and the power is OFF (YES in step S106). It is determined whether or not the reduction mode is set (step S110). Since it is now in the water purification mode, the process returns to step S104 and waits for key input again.

Next, if the reduction / water purification button 103 is pressed (Yes in Step S107), the soft power switch is in an ON state (Yes in Step S108), so the water purification mode is switched to the reduction mode (Step S109).

For this reason, since the soft power switch is in the ON state and the operation mode is the reduction mode (Yes in step S110), a reduction time setting subroutine is called (step S111).

In the return time setting subroutine, the set value of the rotary switch 311 is read to refer to the rotary switch table 36 (see FIG. 15) to determine the basic return time and the reverse voltage application pattern (step S201). A reduction time correction amount is obtained by referring to the two-dimensional time correction table 37 (see FIG. 16) based on the (flowing water amount) and the count value of the elapsed time counter (elapsed time after reduction interruption or completion) (step S202). Next, the reduction time is calculated as the product of the basic reduction time and the reduction time correction amount (step S203), and the reduction time is set in the reduction time counter (step S204).

After returning to the main routine after completion of the reduction time setting subroutine, high-frequency alternating current and direct current are supplied to the electrolytic cell unit 25 to start a reduction operation (step S112).

On the other hand, a timer interrupt routine is started by a timer interrupt at regular intervals, the running water stop time counter is counted down (step S301), and if it is not being returned (NO in step S302), the elapsed time counter is counted up (step S301). S303). If the reduction is in progress (Yes in step S302), the reduction time counter is counted down (step S304), and the reduction time set in the reduction time counter has not elapsed and the reduction has not ended (No in step S305). Then, the interrupt is terminated. If the reduction time set in the reduction time counter has elapsed and the reduction is completed (Yes in step S305), the interruption is terminated after calling the reduction end processing subroutine (step S306).

In the return end processing subroutine, the count value of the running water counter is initialized (step S401), the count value of the elapsed time counter is initialized (step S402), and the reduction operation is stopped (step S403).

On the other hand, each time a pulse is input from the flow sensor 24, a flow sensor interrupt routine is started, an initial value is set in the running water stop time counter (step S501), and the running water counter is counted up (step S502). As described above, during running water, the flow rate sensor interrupt routine is frequently started before the count value of the running water stop time counter reaches 0, and the running water stop time counter is reset to the initial value every time.

In the main routine, after the reduction starts (step S112), if the reduction / water purification button 103 is pressed (Yes in step S113), the reduction operation is stopped (step S114), and the process returns to step S119 to switch to the water purification mode. .

If the reduction / water purification button 103 is not pressed (No in Step S113) and the ON / OFF button 101 is pressed (Yes in Step S115), it is determined whether the reduction is in progress (Step S116). If not being reduced, the process returns to step S104 to wait for key input. If it is during reduction (Yes in step S116), the reduction operation is stopped (step S117), the soft power switch is set to the OFF state (step S118), and the process returns to step S104 to wait for key input.

If the reduction / purification button 103 is not pressed (NO in step S113) and the ON / OFF button 101 is not pressed (NO in step S115), it is determined whether there is running water (step S119). If there is, the reduction operation is started (step S120), and the flag F is set so as to record that there was running water (step S121). If there is no running water (NO in step S119), steps S120 and S121 are skipped.

Next, it is determined whether or not the running water is stopped based on whether or not the count value of the running water stop time counter subtracted in the timer interruption routine is 0 (step S122). If the running water is not stopped, the process waits until the running water stops (Yes in Step S122). If the flag F is set (Yes in Step S123), the flag F is reset (Step S124), and the process returns to Step S111. Call the reduction time setting subroutine.
