【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 and 2 show a first embodiment of a bath according to the present invention. In the figure, reference numeral 1 denotes a bathtub body for accommodating bathing water 2, and 3A, 3B, 3C are supported on the inner surface of the bathtub body 1 so as to be positioned below the surface of the bathing water 2. , The second and third electrodes. As the first and second electrodes 3A and 3B, electrodes made of conductors that are beneficial or harmless to the human body and reduce the redox potential are used. As such a conductor that is beneficial or harmless to the human body and lowers the redox potential, for example, a metal such as Zn, Mg, or Ge, or charcoal can be used. The third electrode 3C is grounded. Reference numeral 30 is a bath for heating the bathing water 2.

Reference numeral 4 is, for example, a DC power source of 10V to 50V, and 5A and 5B are respectively connected to the DC power source 4 via a variable resistor 6, and convert the DC voltage from the DC power source 4 into a high-frequency alternating current. The first and second high frequency switches are alternately applied to the first and second electrodes 3A and 3B. These first and second high frequency switches 5A and 5B are composed of transistors 7A and 8A and 7B and 8B. Reference numeral 9 is a capacitor connected between the first and second electrodes 3A and 3B.

Reference numeral 10 is a high-frequency switching command circuit including a flip-flop circuit that gives a high-frequency switching command to the first and second high-frequency switches 5A and 5B via resistors 11A and 11B, and 12 is a high-frequency switching command circuit 10 from 20 kHz. It is a high-frequency oscillator that gives a high-frequency signal of 100 kHz. A power supply circuit 13 for alternately applying high-frequency alternating current to the first and second electrodes 3A, 3B is configured by these 4 to 12 constituent elements.

Next, a method of reforming bathing water in such a bathtub will be described. A high-frequency alternating current of 20 kHz to 100 kHz at a voltage of 10 V to 15 V, for example, is applied to the first and second electrodes 3A and 3B in the bath body 1 containing the bathing water 2 to the first and second high frequency switches 5A. , 5B are applied alternately. Such high-frequency alternating current gives a high-frequency signal from the high-frequency oscillator 12 to the high-frequency switching command circuit 10, and gives a high-frequency switching command from the high-frequency switching command circuit 10 to the first and second high-frequency switches 5A and 5B. The first and second high frequency switches 5A and 5B are turned on and off at a high cycle, and the output from the DC power supply 4 is alternately applied to the first and second electrodes 3A and 3B.

When high-frequency alternating current is applied to the first and second electrodes 3A and 3B in this way, water is rectified between the first and second electrodes 3A and 3B and the third electrode 3C. A direct current alternately flows from the first electrode 3A to the third electrode 3C and from the second electrode 3B to the third electrode 3C.

As a result, the bathing water 2 is electrolyzed, bubbles are generated in the bathing water 2, electrons flow through the third electrode 3C to the ground side, and the oxidation-reduction potential of the bathing water 2 is reduced, resulting in reduction. It becomes an electric potential.

In particular, in this case, as the first and second electrodes 3A and 3B, electrodes made of a conductor that is beneficial or harmless to the human body and lowers the redox potential are used. An inorganic substance having a small electric resistance is melted out and the redox potential of the bathing water 2 can be lowered from, for example, +250 mV to +100 mV or less. The electrodes 3A and 3B made of a conductor that lowers the redox potential dissolves during electrolysis of water and acts to lower the redox potential.

The bathing water 2 having a reducing potential deprives the surface of the skin of active oxygen and returns the skin to normal cells.

When the bath water 2 is treated by using the first and second electrodes 3A and 3B made of a conductor such as Zn, the bath water 2 dissolves metal ions that are beneficial to the human body. It is possible to treat or prevent illness. For example, Zn and Ge are said to be effective in treating skin diseases and atopic dermatitis.

When Ioishi is put in the bathing water 2 in the bath body 1 and the bathing water 2 is brought to the restoring potential as described above, various mineral components are dissolved in the bathing water 2 to obtain a hot spring effect. I found out that

Table 1 shows gut water (Ishishimizu, which is said to be delicious water in Yao-cho, Neguro-gun, Toyama Prefecture), and water obtained by electrolyzing gut water to a reduction potential (+100 mV) by the means of the present invention. The analysis results of the components with water obtained by putting Ioishi in gut water and electrically treating to the reduction potential (+100 mV) by the means of the present invention are shown.

[0027]

[Table 1] Further, the above-described embodiment is useful when the bathing water 2 does not move much, but as shown in FIG. 3, in the bathtub in which the bathing water 2 in the bath body 1 and the bath 30 is circulated by the pump 40. The first, second, and third electrodes 3A, 3B, 3C can be arranged in the circulation channel 41.

FIG. 4 shows a second embodiment of the bathtub used in the present invention. The parts corresponding to those of the first embodiment described above are designated by the same reference numerals.

In the figure, 3D is a fourth electrode, which is arranged to face the inner surface of the bath body 1 together with the first to third electrodes 3A to 3C as shown in the figure. In this case, the first and second electrodes 3A and 3B are also formed of a conductor that is beneficial or harmless to the human body and lowers the redox potential, as in the first embodiment. 14A and 14B are low-frequency switches for alternately grounding the third and fourth electrodes 3C and 3D in a low cycle, and 15 is a high-frequency signal of the high-frequency oscillator 13, which is, for example, 1/2 ¹⁴ It is a low frequency switching command circuit which divides the frequency and gives a low frequency switching command to the low frequency switches 14A and 14B via the resistors 16A and 16B. Reference numerals 17A and 17B are resistors for connecting the collectors of the low-frequency switches 14A and 14B, which are transistors, to the positive side of the DC power supply and holding the third or fourth electrodes 3C and 3D at a positive potential when the switch is turned off.

In this embodiment, similarly to the first embodiment, a high frequency alternating current of 20 kHz to 100 kHz at a voltage of 10 V to 15 V is applied to the first and second electrodes 3 A and 3 B at the first and second high frequencies. The switches 5A and 5B act so that they are applied alternately.

On the other hand, the low-frequency switches 14A and 14B are supplied with a low-frequency signal by the low-frequency switching command circuit 15, and these low-frequency switches 14A and 14B are alternately turned on in a low-frequency cycle, whereby the third and third switches are provided. The fourth electrodes 3C and 3D are alternately grounded. The electrode 3C or 3D that is turned off is held at a positive potential via the resistor 17A or 17B.

In this way, the direct current is alternately applied to the third or fourth electrode 3C, 3D by the rectifying action of water from the first and second electrodes 3A, 3B to which the high frequency alternating current is alternately applied. It will be washed away.

Further, if the third or fourth electrodes 3C and 3D, which are not grounded, are held at a positive potential, it is possible to prevent dust such as calcium from adhering to the electrode surface, which facilitates maintenance. Becomes

When the voltage applied between the first and second electrodes 3A and 3B is a rectangular wave, the redox potential can be lowered more efficiently.

In the first and second embodiments, the bath water 2 may contain salt, baking soda, or the like. By doing so, the bathing effect can be further improved.

 As described above, according to the bathtub of the present invention, the following effects can be obtained.

According to the first aspect of the present invention, the first and second electrodes are formed of conductors that are beneficial or harmless to the human body and reduce the oxidation-reduction potential. Therefore, when electrolyzing the bath water using these electrodes, A metal ion or an inorganic substance having a small electric resistance is dissolved from the conductor that lowers the redox potential, the conductivity of the bathing water is increased, and the redox potential of the bathing water can be efficiently lowered.

In particular, when a metal beneficial to the human body is used as a conductor that lowers the redox potential, a metal ion beneficial to the human body dissolves in the bathing water, which is effective in treating or preventing diseases. .

[0039] Further, according to the bathing water subjected to the electric treatment, the human body can be bathed at a higher temperature without feeling irritation and the body can be warmed.

In the device of the second aspect, since the bath body also serves as the third electrode, the configuration of the bath can be further simplified.
