[0002]
[Prior art]

[0003]
A conventional continuous electrolysis type alkaline ion water conditioner will be described below.
[0004]
FIG. 2 is a schematic structural diagram of a conventional alkaline ionized water device. As shown in the figure, this alkaline ion water purifier includes a raw water pipe 1 such as tap water, a faucet 2, and an alkaline ion water purifier main body 3 connected to the raw water pipe 1 via the faucet 2 as shown in the figure. , Water purification unit 4 equipped with activated carbon that adsorbs residual chlorine, trihalomethane, mold odor, etc. in raw water and hollow fiber membrane that accurately removes general bacteria and impurities, and confirms water flow and gives control instructions to control means A flow rate sensor 5, a calcium supply unit 6 that imparts calcium ions such as calcium glycerophosphate and calcium lactate to the raw water to increase the raw water conductivity, and water that has passed through the flow rate sensor 5 is electrolyzed to generate alkaline ionized water, An electrolytic cell 7 that generates acidic ionized water, a diaphragm 8 that divides the inside of the electrolytic cell 7 into two, and forms two electrode chambers, and an electrode plate disposed in each electrode chamber that is divided into two by the diaphragm 8 9 and 10 A drain pipe 11 that discharges water on the electrode plate 10 side (acidic ion water when the electrode plate 10 is an anode) and an alkaline ion water that is disposed near the connection between the electrolytic cell 7 and the drain pipe 11 are efficiently generated.

Ionic water), discharge pipe 15 for draining accumulated water and washing water in electrolytic cell 7, water purifier detection sensor 16 for detecting the presence or absence of water purifier 4, power on plug 17, and power on plug 17 Power supply unit that converts AC power into DC power 8, the control means 19 for controlling the operation of the alkaline ionized water body 3, the operation display unit 20 for displaying the operational state of the alkaline ionized water body 3, and drainage by closing the valve in the water purification mode An electromagnetic valve 21 that cuts and opens and drains water when alkaline ionized water and acidic ionized water are generated, and an electrolytic current detector that detects the amount of current flowing between the electrode plates 9 and 10 when alkaline ionized water and acidic ionized water are generated 22 is provided.
[0005]
Next, the operation | movement at the time of producing | generating the alkaline ionized water is demonstrated about the conventional alkaline ionized water apparatus comprised by the above each component below.
[0006]
The user presses the mode selection button of the operation display unit 20 to select and set the alkaline ionized water generation mode, the acidic ionized water generation mode, or the purified water mode, and operates in the alkaline ionized water generation mode or the acidic ionized water generation mode. A desired pH intensity is selected with the pH intensity button of the display unit 20 and the faucet 2 is opened.
[0007]
The raw water passed through the faucet 2 is free of impurities such as residual chlorine, trihalomethane, musty odor, and general bacteria in the raw water in the water purification unit 4, and calcium glycerophosphate and lactic acid in the calcium supply unit 6 through the flow sensor 5. After calcium or the like is dissolved and treated with water that is easily electrolyzed, water is passed through the electrolytic cell 7.
[0008]
On the other hand, 100 VAC is supplied from the power-on plug 17, and a DC voltage / current required for electrolysis is generated by the transformer in the power supply unit 18 and the control DC power supply, and the electrode plate of the electrolytic cell 7 is connected via the control means 19. Power required for electrolysis is supplied to 9 and 10. At this time, if an electrode plate to which a positive voltage is applied relatively is an anode and an electrode plate to which a negative voltage is applied is a cathode, an anode chamber and a cathode chamber partitioned by a diaphragm 8 are formed in the electrolytic cell 7. In the alkaline ion water generation mode, the electrode plate 10 serves as an anode and the electrode plate 9 serves as a cathode. In the acidic ion water generation mode, the electrode plate 9 serves as an anode and the electrode plate 10 serves as a cathode.
[0009]
Now, the control means 19 after passing water reads the signal of the flow sensor 5, and when the flow level exceeds a certain amount, it judges that this state is passing water. At this time, since the electrolysis conditions have already been set by pressing the generation mode selection button of the operation display unit 20, the control means 19 applies a predetermined voltage to the electrode plates 9 and 10 for electrolysis in the electrolytic cell 7. The operation command is output so that is applied. Thus, in the alkaline ion water generation mode, the electrode plate 9 serves as a cathode and the electrode plate 10 serves as an anode, and alkaline ion water is discharged from the water discharge pipe 13, and in the acidic ion water generation mode, the electrode plate 9 serves as an anode and an electrode. The plate 10 serves as a cathode, and acidic ion water is discharged from the water discharge pipe 13.
[0010]
When the raw water is stopped by the faucet 2, the control means 19 determines that the water flow is stopped by the flow sensor 5, and the voltage application control unit stops voltage application to the electrode plates 9 and 10 of the electrolytic cell 7. Further, in the water purification mode, no voltage is applied to the electrode plates 9 and 10, and the drainage is cut by closing the electromagnetic valve 21, and the purified water is discharged from the water discharge pipe 13.
[0011]
Next, in order to remove impurities such as residual chlorine, trihalomethane, mold odor, and general bacteria in the raw water, the water purification unit 4 gradually clogs and lowers the electrolysis performance. The control means 19 reads the signal of the flow sensor 5 and counts the amount of water flow, and when it reaches a certain amount, the operation display unit 20 displays that it is time to replace the water purification unit 4. Further, clogging may proceed before reaching a certain amount due to the quality of the raw water, but this is the time to replace the water purification unit 4 by monitoring the fluctuation of the signal of the flow sensor 5 with the control means 19. Is displayed by the operation display unit 20.
[0012]
When the water purification unit 4 is attached / detached, the control unit 19 detects the presence or absence of the water purification unit 4 by the water purification unit detection sensor 16 and assumes that a new water purification unit 4 is installed, and sets the water flow count and the water flow state to the initial state. Alternatively, the user can arbitrarily set the water flow count and the water flow state to the initial state by operating the operation display unit 20.
[0013]
Here, in the alkaline ionic water production mode and the acidic ionic water production mode, the control means 19 supplies a DC voltage generated in the power supply unit 18 to the electrode plates 9 and 10 of the electrolytic cell 7. When a constant DC voltage is supplied to the electrode plates 9 and 10, the current flowing between the electrode plate 9 and the electrode plate 10 varies depending on the quality of the tap water and the flow rate of the tap water passing through the water passage. The pH value also changes.
[0014]
When a user selects a desired pH intensity with the pH intensity button of the operation display unit 20, the control means 19 generates a DC voltage generated in the power supply unit 18 within a certain period according to the pH intensity. Alkaline ion water or acidic ion water is produced by varying the time for supplying to 9 and 10. If the tap water has a high electrical conductivity, a large current flows. Therefore, the control means 19 monitors the current flowing between the electrode plate 9 and the electrode plate 10 by the electrolytic current detector 22 so that the current flows over a certain current. Control the supply time so that there is no.
[0015]
About the produced | generated pH value, the produced | generated water discharged from the water discharging pipe 13 can be measured with a pH reagent etc., and can be adjusted with a pH intensity | strength button.
[0016]
[Problems to be solved by the invention]
As described above, the conventional alkaline ionized water device controls the electrolysis by changing the so-called duty of a single DC voltage supplied to the electrode plates 9 and 10 of the electrolytic cell 7 within a certain period. is doing. For this reason, for example, when tap water with very high conductivity or salt water is added to strongly promote the production, the supply time is shortened and the electrolysis current is controlled to be small on average. The peak current increases and stress is applied to the control element.
[0017]
Therefore, an object of the present invention is to provide a safe and highly reliable alkaline ionized water device without adding stress to the control element even in the addition of tap water quality and salt water.
[0018]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, the power supply device has a plurality of output means having a difference in voltage level, and switches the voltage level according to the level of the current for electrolysis flowing in the electrolytic cell, and further the duty is changed. Optimal electrolysis control function by switching the output level to a lower output level when the peak current increases when DC current is supplied, and switching the output level to a higher level when current becomes difficult to flow Alkaline ion water conditioner with
[0019]
According to the present invention, when a certain DC voltage is supplied to the electrolytic cell, if the current flowing between the electrode plates is high, the peak current can be suppressed by lowering the voltage level of the power supply device, making it difficult for the current to flow. case ing to be able to control the desired the pH intensity switches the output level to a higher level. Furthermore, fine control can be performed by varying the duty, and a safe and highly reliable alkaline ionized water device can be realized.
[0020]

[0024]
Embodiments of the present invention will be described below with reference to the drawings.
[0025]
(Embodiment 1)
FIG. 1 is a schematic configuration diagram of an alkaline ionized water device according to Embodiment 1 of the present invention. In FIG. 1, the same reference numerals as those used in the description of the conventional technique are basically the same in the first embodiment, and the detailed description thereof is left to the conventional technique. Omitted.
[0026]
In FIG. 1, 1 is a raw water pipe such as tap water, 2 is a faucet, 3 is an alkali ion water adjuster body, 4 is a water purification unit, 5 is a flow sensor, 6 is a calcium supply unit, 7 is an electrolytic cell, and 8 is Diaphragm, 9 and 10 are electrode plates, 11 is a drain pipe, 12 is a flow rate adjusting unit, 13 is a water discharge pipe, 14 is a solenoid valve, 15 is a water discharge pipe, 16 is a water purifier detection sensor, 17 is a power-on plug, 18 Is a power supply unit, 19 is a control means, 20 is an operation display unit, 21 is a solenoid valve, and 22 is an electrolysis current detection unit, which are configured in the same manner as the prior art shown in FIG.
[0027]
The alkaline ionized water device of the first embodiment is characterized by having the following components. That is, the voltage level (1) 23 which is provided in the power source unit 18 and converts the AC power source from the power-on plug 17 into a DC power source and is one of a plurality of output levels having a voltage level difference, and the voltage level (1) a voltage level (2) 24 having a voltage level difference from 23, a voltage level (1) 23, a voltage level (3) 25 having a voltage level difference from the voltage level (2) 24, and an electrode plate 9 And a voltage level switching unit 26 that switches between the voltage level (1) 23, the voltage level (2) 24, and the voltage level (3) 25 according to the level of the current flowing between them.
[0028]
In the alkaline ionized water device of Embodiment 1 comprising these components, when producing alkaline ionized water and acidic ionized water, the faucet 2 is opened and the raw water passed through the faucet 2 is It passes through the water purification unit 4. The raw water from which impurities have been removed by the water purification unit 4 passes through the flow sensor 5, and the control means 19 reads the signal from the flow sensor 5, and if the flow level exceeds a certain amount, it determines that this state is underwater. At this time, if the alkaline ionized water generation mode or the acidic ionized water generation mode is selected and set by the operation display unit 20, the control means 19 supplies DC power to the electrode plates 9 and 10 from the power supply unit 18, and the alkaline ionized water is supplied. Production or acid ion water production begins.
[0029]
In this electrolysis control, the control means 19 switches the output level of the DC power supplied to the electrode plates 9 and 10 to the voltage level (2) 24 via the voltage level switching unit 26, and the electrolysis current detection unit 22 causes the electrode plate 9 to switch. And the current flowing between 10 and 10 is monitored.
[0030]
In addition, in order to control to a desired pH intensity with the pH intensity button of the operation display unit 20, a DC voltage of the voltage level (2) 24 generated in the power supply unit 18 is supplied to the electrode plates 9 and 10 within a certain period. By controlling the time to perform fine control.
[0031]
Here, when the conductivity of the raw water is high, the current flowing between the electrode plates 9 and 10 increases, and this is monitored by the electrolytic current detector 22 and the supply time within a certain period is shortened so that it does not flow above a certain current. To do.
[0032]
However, when raw water with very high conductivity or salt water is added to strongly promote the generation, the peak current at the time of DC power supply increases, so that the control means 19 outputs via the voltage level switching unit 26. The level is switched to the output level (1) 23 lower than the voltage level (2) 24, and control is performed so as to suppress the peak current.
[0033]
On the contrary, in the case of raw water having a very low electrical conductivity, it becomes difficult for current to flow between the electrode plates 9 and 10, so that the control means 19 is connected to the voltage level (the voltage level switching unit 26). 2) A power level higher than 24 (3) can be switched to 25 and controlled to the desired pH intensity.
[0034]
Here, the principle of water electrolysis will be briefly described. A pair of electrodes are placed in water, and a diaphragm having fine pores is provided between the electrodes so that ionic substances in the water can freely pass therethrough but inhibit the free passage of liquid water itself. When one electrode is connected to the positive electrode and the other is connected to the negative electrode, anions such as chloride ions are attracted to the anode of the electrolytic cell, and conversely, cations such as magnesium ions and calcium ions are attracted to the cathode. . At this time, electrolysis of water occurs when a sufficient voltage is applied between the two electrodes. Oxygen gas or chlorine gas is generated from the anode and H ions are released into water at the same time. Hydrogen gas and the like are generated from the cathode and OH ions are released into water at the same time. As a result, the water on the anode side is a water in which anions such as chloride ions that are offset toward the acidic side are relatively increased, and the water on the cathode side is cations such as sodium ions and calcium ions that are offset toward the alkali side. Relatively increased water. The basic principle of electrolyzed ionic water is to take out and use these waters individually. At this time, the reaction occurring on the surface of each electrode is as follows.
[0035]

As described above, the power supply device includes a plurality of output means having a difference in voltage level, so that the amount of voltage supplied to the electrolytic cell by the quality of raw water can be controlled and optimal electrolysis control can be performed. .
[0036]
A plurality of output means having a difference in voltage level in the power supply device can reduce the difference in output level as much as possible, and perform more optimal electrolysis control by providing as many output means as possible.
[0037]
As described above, according to the alkaline ionized water device of the first embodiment, even in a region where the conductivity of tap water is high, even when salt water is added in order to strongly promote the generation, the current flows excessively. Since the current can be suppressed by lowering the voltage level and can be finely generated by duty control, the control element can be controlled efficiently without stress.
[0038]
【The invention's effect】
As apparent from the above description, according to the present invention, includes a plurality of output means having a difference in power supply voltage level, to switch the selected voltage level by the level of current for electrolysis flows through the electrolytic cell, In addition to duty control, the output level is switched to a low output level when the peak current increases when DC current is supplied, and the output level is switched to a high level when the current becomes difficult to flow. Since the supply voltage to the electrolytic cell is controlled by the water quality , optimum control can be performed, and a safe and highly reliable alkaline ionized water device can be provided.
