Description

Reduced water generator

The present invention relates to a reduced water generator, and more particularly, to a reduced water generator that is easy to use.

In general, a variety of methods for electrolyzing water are known to increase the functionality of the water.

Conventional electrolysis is a method of electrolyzing water to produce alkaline water and acidic water.

In this electrolysis method, when a direct current voltage is applied to the anode and cathode plates installed in the anode chamber and the cathode chamber separated by the diaphragm in the electrolytic cell, acidic and alkaline water are generated in the anode chamber and the cathode chamber, respectively. In addition, an electrolyte such as sodium chloride (Nacl) may be added into the electrolytic cell to activate the electrolysis reaction.

Alkaline water generated in the cathode chamber by the electrolysis method is mainly used as drinking water, and acidic water produced in the anode chamber is mainly used as sterilized water.

In the conventional water treatment method, acidic water and alkaline water are generated at the same time, there is a problem in that the acidic water should be discarded when only alkaline water is used. If it is not available, and the acidity is high, the mineral solubility is low, there is a disadvantage that it is difficult to use the mineral containing mineral components in the production of drinking water.

On the other hand, free radicals generated during metabolic processes of the living body are very oxidative, causing oxidization of genes or cells constituting the living body to cause diseases. As a way to effectively reduce these free radicals, water with low redox potential It is proposed to drink.

The present invention was devised to improve the above problems, and has an object of the present invention to provide a reduced water generator capable of generating reduced water capable of promoting decomposition of active oxygen in vivo by lowering the redox potential of water.

Another object of the present invention is to provide a reduced water generator that is portable and easy to use.
