BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous electrolytic ionic water generator for continuously producing alkaline ionized water and acidic ionized water by electrolyzing tap water and the like, by controlling the DC supply power steplessly. And a controller for adjusting the electrolytic strength.

[0002]

2. Description of the Related Art As a medical substance generator, drinking water such as tap water is subjected to direct voltage application to an anode and a cathode to electrolyze, thereby directly producing alkali ionized water and acidic ionized water. A continuous electrolytic ionized water generator is known. The alkaline ionized water is used to improve the acidic constitution of the diet of mainly human meat and to promote health by drinking, and the acidic ionized water is used for cosmetics such as cleaning the surface of the body.

In this type of electrolytic ionic water generator,
Depending on the purpose of use, P
It is necessary to adjust the H value. In addition, PH of electrolytic ionic water
The value greatly depends on the amount of water flowing to the electrolytic cell, the electric conductivity of the supplied water, the pH of the water quality, and the like. Therefore, conventionally, as a measure for adjusting the electrolytic strength, a method of switching a voltage tap of a power transformer to adjust a DC supply voltage in a plurality of stages, and a method of changing a water flow rate by a water flow valve have been used.

[0004] Incidentally, in the above-mentioned prior art, the user switches the voltage tap of the power transformer or changes the amount of water flow each time the user uses the power transformer.
The operation was complicated. Further, since the DC supply voltage is variably controlled stepwise by switching the voltage taps, the adjustment of the electrolytic strength is also rough, and there is a problem that the PH value of the electrolytic ionized water cannot be adjusted to an optimum value. Therefore,
It is desired to make it possible to control the DC supply power of the electrolytic cell steplessly with a simple operation, and to optimally adjust the PH value of the electrolytic ionized water.

Conventionally, as a prior art similar to the above-mentioned solution, there is Japanese Utility Model Laid-Open No. 1-163494. In this prior art, the electrolytic current is adjusted in a plurality of stages by operating an electrolytic strength adjusting switch, and the electrolytic current supplied to the electrolytic cell is detected, and the current value set by selecting the electrolytic strength adjusting switch is determined. It is shown that the value of the electrolytic current is controlled to be equal.

[0006]

However, in the above prior art, since the electrolytic current is adjusted in a plurality of stages by the electrolytic intensity adjusting switch, the electrolytic intensity cannot be finely adjusted. Therefore, it is difficult to always obtain a target PH value of electrolytic ionized water. Furthermore, since it is a method of controlling the electrolysis current, unlike power control appropriate as an element of the electrolysis strength, it is difficult to set an optimum value and the like.

The present invention has been made in view of this point, and employs an appropriate DC power control method for adjusting the electrolytic strength, and controls this DC voltage steplessly with a simple operation to always control the electrolytic ionized water. The purpose of this is to optimize.

[0008]

In order to achieve the above object, the present invention provides a continuous electrolytic ionic water generator having a power supply circuit for applying a DC voltage to the anode and cathode of an electrolytic cell.

[0009]

According to the above arrangement, when electricity is supplied to the electrolytic cell by the power supply circuit, electrolysis is carried out, and electrolytic ionic water is taken. At this time, when the electrolytic control switch is operated, the DC supply voltage of the power supply circuit is steplessly controlled by the control unit and the switching regulator, and an electrolytic voltage corresponding to the operation of the electrolytic control switch is generated. Is electrolyzed. Therefore, by appropriately operating the electrolysis control switch in any water-flowing state or the like, the electrolysis strength is adjusted to a suitable level, and the electrolyzed ionic water can be optimized.

After stopping the flow of water, the scale removal time is set according to the amount of water flow, and based on the scale removal time, the polarity inversion switch 18 is switched to the reverse connection position by the relay 26 to automatically scale the anode 7 and the cathode 6. Removed.

The control unit 40 has an acid-alkali switch 27 which operates when using either acidic ionized water or alkaline water, an electrolytic adjustment switch 28 which adjusts the electrolytic strength, and a control unit which is used when acidic ionized water is used. An activated melody switch 29 is connected. On the other hand, the display means (LE

Referring to FIG. 3, an embodiment of the control device of the present invention will be described. The electrolytic adjustment switch 28 is, for example, a dial switch that changes the voltage applied to the resistor 28b by rotating the dial 28a, and generates an output voltage v that changes steplessly according to the rotation angle θ as shown in FIG. The switching regulator 16 has a switch element 42 that is turned on and off by a driver 41 in the circuit, and a filter circuit 43 that smoothes the pulse voltage and generates an electrolytic voltage Ec corresponding to the pulse width a is connected to the switch element 42. .

The control unit 40 includes a pulse width control unit 4 to which a pulse signal of a predetermined frequency from the oscillation unit 44 is input.
The output voltage v of the electrolytic adjustment switch 28 is input to the pulse width control means 45. Pulse width control means 45

Further, it has a flow rate detecting means 46 to which a pulse signal from the flow rate sensor 4 is input, and counts the number of pulses to detect a flow rate q. The flow rate q and the output voltage v of the electrolysis control switch 28 are input to the electrolysis determining means 47, and the flow rate q is compared with a preset reference flow rate. Outputs an OFF signal. On the other hand, if the electrolysis control switch 28 is in a non-zero electrolysis position and is equal to or higher than the reference flow rate, the relay 25
Is configured to output an ON signal.

Next, the operation of this embodiment will be described. First, tap water is always introduced into the electrolytic cell 5 through the water inlet pipe 1. A constant voltage is supplied to the control unit 40 by the rectifier circuit 19 and the constant voltage circuit 21 on the secondary side of the power transformer 12. Therefore, when neither the alkaline ionized water nor the acidic ionized water is used, the pulse signal of the flow rate sensor 4 is not input to the control unit 40. Then, the power switch 17 is turned off by the relay 25, the electrolytic cell 5 is de-energized, and is maintained in a non-electrolytic state.

When water is passed from this state, the tap water passes through the filter cartridge 2 to remove residual chlorine from the tap water and flows into the electrolytic cell 5. At this time, a pulse signal from the flow rate sensor 4 is input to the control unit 40 to detect the flow rate. However, when the electrolysis control switch 28 is at the non-electrolysis position of zero, the electrolysis determination means 47 performs the non-electrolysis determination as described above. Upon determination of electrolysis, the electrolyzer 5 enters a non-electrolytic state. Therefore, in this case, tap water from which chlorine has been removed is taken.

On the other hand, when the electrolysis control switch 28 is rotated by a predetermined amount to operate the electrolysis position during the passage of water, the electrolysis determination means 47
And an ON signal is output to the relay 25, and the power switch 17 is turned on by the relay 25. Then, the transformed voltage on the secondary side of the power transformer 12 becomes the rectifier circuit 1
At 4, the voltage is converted to a DC voltage, smoothed by a smoothing capacitor 15 and input to a switching regulator 16. At this time, the output voltage v corresponding to the rotation angle θ is input from the electrolytic adjustment switch 28 to the pulse width control means 45 of the control unit 40, and the pulse width a is set according to the output voltage v. Output to the driver 41. Therefore, the switching element 42 of the switching regulator 16
Is turned on and off by the driver 41 in accordance with the pulse width a of the pulse signal to generate a pulse voltage Ep, and this pulse voltage Ep is processed by the filter circuit 43.

Thus, the DC supply voltage E on the transformer side
s is controlled to a predetermined electrolytic voltage Ec according to the operation of the electrolytic adjustment switch 28. Then, the electrolytic voltage Ec is normally applied to the anode 7 and the cathode 6 of the electrolytic cell 5 via the power switch 17 and the polarity reversing switch 18 at the positive connection position, and the tap water in the electrolytic cell 5 is electrolyzed. become. Therefore, the polarity on the electrode side is changed by the polarity inversion switch 18 to the cathode 6.
By switching to the discharge port 8 on the anode side, alkali ion water containing a large amount of anions is taken. Conversely, when switching to the discharge port 9 on the anode 7 side, acidic ion water containing a large amount of cations is produced. It is withdrawn.

In this case, for example, when the rotation angle θ of the electrolysis control switch 28 is operated to be small under the condition of a small water flow, the pulse width a is set small according to the maps of FIGS. 5 and 6, and as shown by the solid line in FIG. A pulse voltage Ep having a small pulse width is generated. Therefore, the electrolysis voltage Ec is controlled to be low, and the electrolysis strength of the electrolysis tank 5 is adjusted to be weak. Thus, the PH value of the electrolyzed ionic water becomes appropriate for a small amount of water flow. When the rotation amount θ of the electrolytic control switch 28 is increased when the amount of water flow is large, the pulse width a is set to be gradually increased, whereby the pulse voltage Ep also changes as shown by the one-dot chain line in FIG. Is controlled to be high. Therefore, the electrolysis strength is sequentially adjusted to be higher, and the PH value of the electrolyzed ionic water similarly becomes appropriate with respect to the increase in the flow rate.

Further, the electrolytic voltage Ec is steplessly controlled with respect to the rotation angle θ of the electrolytic adjustment switch 28 as shown in FIG. 7 by the maps shown in FIGS. . Thus, in any water flowing state, the electrolytic strength is appropriately adjusted by the electrolytic voltage Ec accompanying the switch operation, and the PH value of the electrolytic ionic water can always be optimized. In addition, the electrolytic adjustment switch 28 can be minutely modified in consideration of not only the flow rate but also the water quality such as the water temperature, so that the PH value of the electrolytic ionized water can be made closer to the target PH value.

[0022]

As described above, according to the present invention,
In a continuous electrolytic ionized water generator, a switching regulator is connected to the power supply circuit, and the DC supply voltage is configured to be variably controlled by operating the electrolytic adjustment switch.
The electrolytic strength of the electrolytic cell can be adjusted appropriately. By operating the electrolysis control switch, the DC voltage can be controlled steplessly to adjust the electrolysis strength arbitrarily.
By optimizing the electrolytic strength with respect to the water quality and the like, the pH value of the electrolytic ionic water can always be optimized, and the operability and reliability are improved. Since the switching regulator converts the DC supply voltage on the transformer side into an electrolytic voltage and applies the electrolytic voltage to the electrolytic cell, safety and the like are improved, and various controls are possible.
