Abstract: Devices for manufacturing hydrogen water without a water storage tank include: a water supply line receiving raw water; an electrolysis part including an oxygen generating chamber and a hydrogen generating chamber individually receiving the raw water. Electrolysis is performed in the oxygen and hydrogen generating chambers. A dissolving part is provided to receive the generated hydrogen and the raw water discharged by a pump and increase a dissolution rate of the hydrogen. A water discharge line outputs the hydrogen water discharged from the dissolving part. The water discharge line includes a large diameter line to decrease a pressure of the hydrogen water output; and a small diameter line provided has an inner diameter less than an inner diameter of the large diameter line and connects an outlet of the dissolving part and an inlet of the large diameter line.

Abstract: A hydrogen water manufacturing system includes: a container-shaped constant pressure maintaining unit receiving water and maintaining a water level; an electrolysis unit including a hermetically sealed container bisected into an oxygen generation chamber and a hydrogen generation chamber with an ion exchange membrane interposed therebetween, wherein the chambers independently receive the raw water from the constant pressure maintaining unit, and a positive electrode plate is provided in the oxygen generation chamber and a negative electrode plate is provided in the hydrogen generation chamber; a fluid pump receiving the water and hydrogen from the hydrogen generation chamber; a dissolution unit having a nozzle to inject the water and the hydrogen supplied from the fluid pump; and a flow rate detection sensor arranged on piping downstream of the dissolution unit to detect supply of hydrogen water and drive the fluid pump and simultaneously supply electrical power to the electrolysis unit.
