[Action]

 When the bath water is filled in the bathtub body, a DC voltage equal to or lower than the electrolysis voltage of the bath water is alternately applied from the power supply circuit to the first and second electrodes while inverting the polarity. A strong electric current flows instantaneously and alternately due to the semiconductor effect of the substances contained in the wash water, such as a metal, to decompose the water molecules into small particles while preventing the electrolysis of the bath water. Increase the solubility of other substances in the wash water.

Therefore, a bad odor or a dissolved substance in water is absorbed in water molecules, and the antibacterial action is enhanced, and at the same time, the stimulating sensation to the skin is softened.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of a bath according to the present invention. In FIG. 1, 1 is a bath tank body, 2 is a water bath, and 3 A and 3 B are arranged in bath water 4 in the bath body 1. The first and second electrodes 5 are a power source for applying a DC voltage equal to or lower than the electrolysis voltage of the bath water 4 while alternately reversing the polarities between the first and second electrodes 3A and 3B. It is a circuit.

The first and second electrodes 3A and 3B may each be composed of a plurality of metal plates.

FIG. 2 shows an example of the power supply circuit 5 described above. The parts corresponding to those in FIG. 1 described above are designated by the same reference numerals.

Reference numeral 7 is a DC power source, and 8 A and 8 B are respectively connected to the DC power source 7 via a constant current resistor 9, and the electrolysis voltage of the water 2 from the DC power source 7 is connected via the constant current resistor 9. The first and second application electrode switching circuits perform switching to alternately apply the following DC voltage. These first and second application electrode switching circuits 8A and 8B are composed of resistors 10A and 10B and transistors 11A, 11B, 12A and 12B, respectively. Reference numeral 13 is an electrode switching command generation circuit that alternately gives switching commands to the first and second application electrode switching circuits 8A and 8B, and 14 is a reference voltage below the electrolysis voltage of water (for example, 0.7 to 1.0 V). Is a reference voltage source for generating. In this embodiment, the reference voltage source 14 is constructed by connecting two diodes 15 in series. The diode 15 connected in series has its anode side grounded and its cathode side connected to the DC power supply 7 via the resistor 16.

Reference numeral 17 compares the DC voltage applied between the electrodes 3 A and 3 B with the reference voltage of the reference voltage source 14, and when the former voltage exceeds the latter voltage, the electrode switching command generation circuit 13 A comparator for outputting a rectangular wave switching signal, and a reference numeral 18 is a resistor connected to an electric path for supplying the voltage of the electrodes 3A and 3B to the comparator 17.

Reference numeral 19 is a waveform correction circuit formed of a flip-flop circuit that shapes the waveform of the switching command signal output from the comparator 17 and corrects the pulse width so that the duty becomes 1: 1. A frequency detector composed of a counter or a tachogenerator for detecting the frequency of the waveform-corrected switching signal, and a reference numeral 21 is a display for displaying the detection result of the frequency detector 20, for example, an alarm. Reference numerals 22, 23, and 24 are resistors, capacitors, and light-emitting diodes connected in series between the output end of the waveform correction circuit 19 and the ground. The light emitting diode 24 acts as another indicator other than the indicator 21. Reference numeral 25 is a bias diode connected in parallel with the light emitting diode 24.

Next, a method of treating the bathing water 4 in the water storage tank 1 by using such a power supply circuit 5 will be described. The reference voltage source 14 is set to a reference voltage of, for example, 0.7 to 1.0 V, which is optimal for water treatment. This reference voltage is used as one input of the comparator 17. The comparator 17 receives the DC voltage applied to one of the electrodes 3A and 3B as the other input, and outputs a rectangular wave switching signal every time the DC voltage applied to the electrodes 3A and 3B exceeds the reference voltage. Are sequentially output.

Each time this switching signal is applied, the electrode switching command generation circuit 13 alternately gives a switching command to the first and second application electrode switching circuits 8A and 8B. As a result, the first and second application electrode switching circuits 8A and 8B are alternately conducted, and the DC voltage of the DC power supply 7 is inverted in polarity and applied alternately to the first and second electrodes 3A and 3B. . The voltage applied to the electrode 5A or 5B at this time is input to the comparator 17 as described above.

When the polarity of the DC voltage applied to the electrodes 3A and 3B is switched in this manner, the polarity of the DC voltage applied to the electrodes 3A and 3B changes every time the reference voltage is reached, as shown in FIG. It will be reversed. Therefore, the existence time of the peak voltage is shortened, and electrolysis of water can be prevented. When the water quality changes, the electrostatic capacitance between the electrodes 3A and 3B also changes, so the rising characteristics of the DC applied voltage change and the polarity switching cycle automatically changes.

As shown in FIG. 3, the charge / discharge waveforms are different because of the semiconductor action of water. It is effective to set the value of the constant current resistor 9 so that the water semiconductor action occurs. It can treat various water. When the value of the constant current resistor 9 is adjusted so that the waveform shown in FIG. 3 is obtained, the frequency is not changed much due to the fluctuation of the power source, the voltage becomes stable, and the electrolysis of water does not occur.

On the other hand, the switching signal of the comparator 17 is shaped and corrected by the waveform correction circuit 19 so that the duty becomes 1: 1 and the output thereof is given to the frequency detector 20 and the light emitting diode 24. The frequency detector 20 detects the polarity inversion switching frequency, and the result is displayed as an alarm on the display 21. The light emitting diode 24 continuously lights up when the polarity inversion switching frequency is high, and blinks when it is low.

Further, for example, when the outside air temperature becomes high, it is necessary to lower the reference voltage. However, if the reference voltage source 14 is composed of the diode 15 as in the present embodiment, the diode 15 is affected by the temperature change. The characteristic of changes, and the reference voltage can be automatically corrected.

The reference voltage source 14 can use another power source capable of switching and outputting various voltages.

Further, control such as automatic switching of the voltage of the voltage switching reference voltage source 14 or automatic switching of the resistance value of the constant current resistor 9 can be performed by the output of the frequency detector 20. it can.

FIG. 4 shows another embodiment of the power supply circuit 5 used in the present invention. The parts corresponding to those in FIG. 2 described above are designated by the same reference numerals.

In the figure, reference numeral 26 is a sawtooth wave voltage generation circuit for generating a sawtooth wave voltage equal to or lower than the electrolysis voltage of water, and 8A and 8B are sawtooth wave voltage from the sawtooth wave voltage generation circuit 26. An applied electrode switching circuit that performs switching to alternately apply to the second electrodes 3A and 3B. 13 is switched to the first and second applied electrode switching circuits 8A and 8B based on a cycle of generating a sawtooth wave voltage. It is an electrode switching command generation circuit that issues a command.

The sawtooth wave voltage generation circuit 26 includes a charging circuit 29 that includes a variable resistor 27 and a capacitor 28 and that is charged from the DC power supply 7, and a plurality of series connections that are connected to the DC power supply 7 via the resistor 16. A reference voltage source 14 composed of a diode 15 of the above, a comparator 17 for comparing the voltages of these two and outputting a switching signal when the charging voltage of the capacitor 28 exceeds the reference voltage of the reference voltage source 14, and for preventing chattering. By a resistor 30, a capacitor 31, resistors 32 and 33, and a switching transistor 34, a discharge circuit 35 for discharging the capacitor 28 when the comparator 17 outputs a switching signal, and charging and discharging of the capacitor 28. The sawtooth wave voltage amplifier 36 amplifies the sawtooth wave voltage.

The saw-tooth wave voltage amplifier 36 is composed of an impedance conversion buffer amplification section 37 and amplification transistors 38 and 39.

Next, a method of treating the bathing water 4 in the water storage tank 1 using such a power supply circuit 5 will be described.

The reference voltage source 14 is optimal for water treatment, for example, 0.7 to 1. A reference voltage of 0V is set.

This reference voltage is input to one of the comparators 17. The comparator 17 uses the voltage charged in the capacitor 28 of the charging circuit 29 as the other input. The comparator 17 sequentially outputs a rectangular wave switching signal every time the charging voltage of the capacitor 28 exceeds the reference voltage. Each time this switching signal is output, the switching transistor 34 of the discharge circuit 35 is turned on, and the capacitor 28 is discharged.

A sawtooth wave voltage is formed by such an operation, this is amplified by the sawtooth wave voltage amplifier 36, and applied to the first and second electrodes 5A and 5B via the application electrode switching circuit paths 8A and 8B. To be done.

Since the switching signal is output from the comparator 17 every time the sawtooth wave voltage is generated, the electrode switching signal is output from the electrode switching command generation circuit 13 to the first and second electrodes 3A and 3B. Means that sawtooth wave voltages as shown in FIG. 3 are applied alternately.

The sawtooth wave voltage applied to the electrodes 3A and 3B is inverted in polarity every time the reference voltage is reached as shown in FIG. Therefore, the existence time of the peak voltage is shortened, and the electrolysis of water can be prevented.

The different charge / discharge waveforms as shown in FIG. 3 are due to the action of the semiconductor as described above, which enables effective water treatment.

The reference voltage source 14 can use another power source capable of switching output of various voltages as described above.

By using the power supply circuit 5 as shown in FIG. 2 or 4, a DC voltage lower than the electrolysis voltage of the bath water 4 is alternately applied to the first and second electrodes 3A and 3B by inverting its polarity. When applied, the electrolysis of the bath water 4 can be prevented, and when the polarity is reversed, a powerful power source instantaneously flows due to the semiconductor effect of the contained substance such as metal in the bath water 4, and the bath water 4 The above-mentioned molecules are decomposed into small particles, the solubility of other substances in the bath water 4 is increased, and the sensation of the bath water 4 on the skin is softened.

Therefore, the sensible temperature becomes low, the malodor and the melt in water are absorbed by the bathing water 4, and the bathtub body 1 and the bathtub 2 can be cleaned cleanly.

The bath water 4 which has been subjected to the water treatment also has an antiseptic action, so that the metal rust such as a faucet can be removed and it can be beautiful.

The above-described embodiment is useful when the bath water 4 does not move much, but as shown in FIG. 5, the bath water 4 in the bath body 1 and the bath 2 is circulated by the pump 40. In a circular stirring bath, for example, the first and second electrodes 42A and 42B are installed in the circulation flow channel 41 so as to face each other, and a constant voltage direct current of 4 to 6 V is applied to this. Even if it is applied by the power supply circuit 43, the same effect as described above can be obtained.
