Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ion water producing apparatus for producing alkaline water or acidic water by electrolysis or electrodialysis, and more specifically to improvement of the applied electric field.

[0002]

2. Description of the Related Art Ionized water produced by applying an electric field to tap water is said to have an excellent effect on health and beauty, and has received a great deal of attention in recent years. . As this ionized water production apparatus, various apparatuses such as those disclosed in Japanese Patent Publication No. 4-76752 are known, and they are commercially available to the public.

By the way, the conventional ionized water producing apparatus obtains a predetermined AC voltage from a commercial power supply voltage by using a power transformer, and rectifies this AC voltage to obtain a DC voltage for electrodialysis. Since the power transformer is used as described above, there is a problem that the device becomes large and heavy.

Further, since the electrolysis is carried out only by a constant DC voltage, there is a disadvantage that the ionization is not always carried out efficiently. That is, it is considered that various ionic substances such as calcium exist in tap water, and positive ions and negative ions are attracted to each other before application of an electric field. In order to separate the ions in such a state to generate acidic or alkaline ionized water, it is necessary to break the bond between the ions and separate the ions. However, there is a limit to performing such an action only with a DC electric field.

Further, even if it is said that ionized water has a relatively low pH level for use with drinking water and lotion, that is, it has a low pH level for acids and alkalis, and has a high pH level depending on the application. In some cases, those with a high degree of acid or alkali are required. For example, it is said that ion water, which has a very high degree of acidity, exerts a very excellent effect on soil of dense crops, but conventional acid water uses salt to increase the degree of acidity. However, in such acidic water, the salt content may adversely affect concentrated crops.

The present invention has been made in view of these points, and a first object thereof is to provide an ionized water producing apparatus suitable for downsizing and weight saving. The second purpose is to perform ion separation efficiently. The third purpose is acidity,
Alternatively, it is to efficiently obtain highly alkaline ionized water.

[0007]

To achieve the above object, the first invention is to apply a voltage between an anode and a cathode,
An ionized water production apparatus for electrolyzing water between these electrodes is characterized by including pulsed voltage generation means for outputting a pulsed voltage as a voltage for electrolysis.
2nd invention is provided with the DC voltage generation means in the said ionized water manufacturing apparatus in addition to the said pulsed voltage generation means,
The direct current voltage output from this and the pulsed voltage output from the pulsed voltage generating means are superimposed and applied to water.

A third aspect of the invention is an ion water producing apparatus in which a voltage is applied between an anode and a cathode to electrolyze water between the electrodes, and a third electrode is provided between the anode and the cathode. It is characterized by A fourth aspect of the present invention is an ionized water production apparatus in which a voltage is applied between an anode and a cathode to electrolyze water between the electrodes, and a plurality of electrolysis layers including the anode and the cathode are connected in series. It is characterized by

[0009]

According to the invention, a pulsed voltage is used for electrolysis. As a result, ion decomposition is performed more efficiently than DC voltage, and electrolysis is promoted. Further, another electrode is provided between the anode and the cathode of the electrolysis layer. This electrode is used not only when a DC voltage is superimposed on a pulsed voltage, but also when adjusting the pH value. Further, by connecting a plurality of electrolysis layers in series and performing electrolysis, highly acidic and highly alkaline ionized water can be obtained.

[0010]

Embodiments of the ion water production apparatus according to the present invention will be described below with reference to the accompanying drawings. <First Embodiment> First, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows the configuration of the first embodiment. In the figure, a thyristor (bidirectional thyristor) is used as an AC power source 10 such as a commercial power source.
A rectifier 12 is connected to this thyristor rectifier 1
A diode bridge 14 is connected to the output side of 2. The positive side of the output side of the diode bridge 14 is connected to the anode 18 of the electrolysis layer 16,
The minus side is connected to the cathode 20 of the electrolysis layer 16.

Of these, the thyristor rectifier 12 is
A single or a plurality of thyristors and a control gate pulse circuit are included to obtain a pulse waveform voltage described later. The diode bridge 14 acts as a full-wave rectifier for full-wave rectifying and outputting the input voltage. The electrolysis layer 16 has a configuration in which an ion exchange membrane 22 is provided between an anode 18 and a cathode 20, and tap water is supplied between these electrodes 18 and 20 as indicated by an arrow FA. .

Next, the operation of the above-described first embodiment will be described. For example, 100 V output from the AC power source 10 is output.
Is supplied to the thyristor rectifier 12, where a part of its waveform is extracted. Then, this pulse waveform is supplied to the diode bridge 14, where the pulse in the negative direction is inverted in the positive direction. FIG. 2 shows an example of such a voltage waveform. In this example, the frequency is 6
The frequency is 0 Hz, that is, the period is 1/60 sec, the peak voltage is 125 V, and the pulse width is 2.3 ms. Such a pulse voltage is applied between the electrodes 18 and 20 of the electrolysis layer 16. Then, a pulsed electric field corresponding to the pulse voltage is formed between the electrodes 18 and 20.

By the way, tap water exists between the electrodes 18 and 20, but various ions such as calcium and magnesium exist in the tap water, and normally, positive ions and negative ions are formed. It is thought that they are in an electrically neutral and stable state by attracting each other. When a pulsed electric field as shown in FIG. 2 is formed in such a state, the attracted ions are easily released from the bond and move toward the corresponding electrode. That is, the negative ions move toward the anode 18, and the positive ions move toward the cathode 20.

Here, the effect of electrolysis by the pulse voltage of this embodiment and the effect of electrolysis by the conventional DC voltage will be compared with reference to FIG. FIG. 3 shows the relationship between the electric current measured by applying both methods to the same device and the pH of the alkaline water. In the figure, the lower graph G
A and GB are current graphs, and upper GC and GD are p
It is a graph which shows H. Graphs GA and GC show the case of the conventional direct current, and graphs GB and GD show the case of the pulse waveform of the present embodiment. The horizontal axis is the electrolysis voltage (effective value).

As shown in these graphs, current, pH
In addition, the value of this example is higher than that of the conventional direct current, and it can be seen that the electrolysis effect is more effective in this example than in the conventional case. By such electrolysis, acidic water is obtained on the anode 18 side and alkaline water is obtained on the cathode 20 side. These are taken out from the electrolysis layer 16 as shown by arrows FB and FC.

As described above, according to the first embodiment, there are the following effects. (1) Electrolysis can be efficiently performed by the pulse voltage. (2) Since the thyristor rectifier is used and the power transformer is not used, the size and weight of the device can be reduced, which is advantageous in terms of cost and is particularly convenient for home use. . (3) By controlling the gate in the thyristor rectifier, the applied voltage can be easily changed to change the acidity and alkalinity of the ion water.

<Second Embodiment> Next, a second embodiment of the present invention will be described with reference to FIGS. In addition,
The same reference numerals are used for the same or corresponding components as in the above-described first embodiment (the same applies to the following embodiments).

In the figure, the output side of the AC power supply 10 is connected to a pulse voltage generator 30 and a DC voltage generator 32, respectively, and the output sides of these voltage generators 30 and 32 are connected to output terminals of the same polarity. There is. The positive side is connected to the anode 18 of the electrolysis layer 16, and the negative side is connected to the cathode 20 of the electrolysis layer 18.

According to this embodiment, both the pulse voltage output from the pulse voltage generator 30 and the DC voltage output from the DC voltage generator 32 are applied between the electrodes 18 and 20 of the electrolysis layer 18. Will be applied. That is, a voltage as shown in FIG. 5 is applied between the electrodes 18 and 20. In the figure, EA is a pulse voltage output from the pulse voltage generator 30, and EB is a DC voltage output from the DC voltage generator 32.

Among the above voltages, the ion separation described in the first embodiment is effectively performed by the action of the pulse voltage EA. Then, by the action of the DC voltage EB, the negative ions are attracted to the anode 18 side and the positive ions are attracted to the cathode 20 side. As described above, according to the present embodiment, the separated ions can be more efficiently collected at the corresponding electrode.

<Third Embodiment> Next, a third embodiment of the present invention will be described with reference to FIG. This example
Although it is basically the same as the second embodiment, an electrode is added to apply a pulse voltage and a DC voltage. In the figure, the positive output side of the DC voltage generator 32 is connected to the anode 42 of the electrolysis layer 40, and the negative output side is connected to the cathode 44. The positive output side of the pulse voltage generator 30 is connected to the intermediate electrode 46 provided between the electrodes 42 and 44 of the electrolysis layer 40, and the negative side is connected to the cathode 44. The intermediate electrode 46 is formed in a mesh shape so that ions can pass therethrough.

According to this embodiment, a DC electric field is formed between the anode 42 and the cathode 44, and the intermediate electrode 46 and the cathode 44 are formed.
A pulsed electric field is formed between and. Therefore, both the DC electric field and the pulse electric field are formed between the intermediate electrode 46 and the cathode 44, and the same effect as the second embodiment can be obtained.

The intermediate electrode 46 and the anode 42 or the cathode 4
An application is also possible in which a DC voltage is applied between the four or both, and the pH value is adjusted by adjusting the voltage value. Furthermore, you may make it provide a 4th, 5th electrode.

Further, a rectangular wave voltage is output from the rectangular voltage generator 54, and a half wave rectified waveform and a full wave rectified wave are respectively output from the half wave rectified voltage generator 56 and the full wave rectified voltage generator 58. Waveform voltage is output.

FIG. 1B shows a constitutional example of the electrolysis layers 60 to 68. Although each of the electrolysis layers 60 to 68 may be provided separately and independently, the electrolysis layers 60 to 68 may have a continuous structure as shown in FIG.

Further, in this case, in each of the electrolysis layers 60 to 68, since electrolysis is performed with different voltage waveforms, p
The control of H can also be easily performed from various angles.

As described above, according to the fourth embodiment, since two or more electrolysis layers are connected in series to perform electrolysis, it is possible to obtain ionic water having a high degree of acid or alkali. You can In particular, since it is possible to obtain acidic water with a low pH, that is, a high degree of acidity, without the use of common salt as in the past, salt is said to have an adverse effect on concentrated crops when used for soil improvement of concentrated crops. Such inconvenience can be avoided.
