Description

  The present invention relates to a reduced water generator that generates reduced water having a low oxidation-reduction potential.

  The tap water used for daily drinking deteriorates the taste of water due to chlorine added for sterilization, and further, residual chlorine and organic substances in the water combine to be unfavorable for the human body such as trihalomethane. There is a possibility that a substance is generated, and from this point of view, there is a demand for reforming water with good health.

By the way, as a method for reforming such water, JP-A-5-228474, JP-A-5-228475, and JP-A-6-254567 disclose methods for producing reduced water. In such a method, a first electrode, a second electrode, and a third electrode are respectively disposed in a required electrolytic cell, and a high frequency is supplied to the first and second electrodes from an AC power source via a high frequency oscillator or the like. While applying an alternating voltage, a direct current is passed through the water between the first and second electrodes and the third electrode while the third electrode is grounded, and the water in the electrolytic cell is electrolyzed to have a low redox potential. It is supposed to produce reduced water. At this time, the reason for lowering the oxidation-reduction potential is that by applying an AC voltage to the first and second electrodes, elution of metal ions and generation of oxygen gas occur in the first and second electrodes, On the other hand, the generation of hydrogen gas occurs in the third electrode, and the hydrogen gas generated by the above reaction dissolves into the liquid in a supersaturated state, resulting in an increase in hydrogen and hydrogen gas as a reductant compared to oxygen as an oxidant. Thus, it is presumed that the redox potential is lowered.

The best mode for carrying out the present invention will be described below based on an embodiment shown in the drawings.

FIG. 1 shows an embodiment of the present invention. In the figure, 1 is a 100V commercial AC power source, 2a and 2b are a pair of AC power lines connected to the AC power source 1, and 3 is an AC voltage 12-12. A transformer interposed between the pair of AC power supply lines 2a and 2b to reduce the voltage to 24V, 4 and 5 are metal first electrodes connected to one AC power supply line 2a via branch lines 6a and 6b. The second electrode 7 is a metal third electrode connected to the other AC power supply line 2b via a diode 8 so as to convert AC to DC.
