Description

  The present invention relates to a hydrogen water generator that easily electrolyzes drinking water at home to generate electrolytic hydrogen water.

  In general, tap water is neutral (pH 7.0) to nearly acidic, and drinking water marketed in plastic bottles has a pH of about 8.0. By subjecting these potable waters to electrolysis, the electrolytic hydrogen water (reduced water) increases calcium ions, magnesium ions, sodium ions, potassium ions and the like, which are positive ions, by about 15 to 20% from the raw water. Electrolytic hydrogen water (reduced water) is rich in hydrogen and is alkaline water having a pH of 9.0 to 10.0.

Conventionally, there has been known a hydrogen water generating device that allows a user to drink drinking water directly in a cup, such as being able to generate hydrogen water with a high dissolved amount of hydrogen gas without having a complicated structure and being easy to use. (See Patent Document 1).
This known technique includes a beverage container capable of storing drinking water, an electrolysis plate having an anode plate and a cathode plate disposed substantially horizontally inside the beverage container, and from the anode plate and the cathode plate to the outside of the beverage container. A hydrogen water generator comprising: a conductive portion disposed; and a power feeding portion that supplies power to the anode plate and the cathode plate via the conductive portion.

In this hydrogen water generator, a user can drink drinking water directly in a cup, but the conductive portion has a conductive terminal exposed on the outer surface of the beverage container, and penetrates the bottom portion of the beverage container. A rubber packing is installed to prevent the drinking water from leaking. However, it is impossible to completely prevent water leakage, and there is a concern about poor conduction due to corrosion of the conductive terminals of the conductive portion and the power supply terminals of the power supply portion.
Therefore, the development of a non-contact power supply type hydrogen water generator that can eliminate the above-described drawbacks has been desired.
