Abstract
A carbonic water production apparatus equipped with a carbonic acid gas dissolving apparatusand a circulation pump, wherein water in a bathis circulated by the circulation pump, and a carbonic acid gas is fed into the carbonic acid gas dissolving apparatusto dissolve the carbonic acid gas in the water. The circulation pumpis a positive-displacement metering pump having a self-priming ability. A carbonic water production method using this apparatus is also provided, including an early step for producing carbonic water and a concentration maintaining step for the carbonic water. The carbonic water production apparatus includes a control for controlling the feeding pressure of carbonic water gas to give an intended concentration of carbonic acid gas. The carbonic water production apparatus automatically discharges out a drain. The carbonic water production apparatus is combined with a portable foot bath.
