Patent ID: 6921063

Claim:
A gas-dissolved water producing apparatus comprising: a dissolving section for dissolving a solution gas into water to form gas-dissolved water; a solution gas supply channel for guiding the solution gas into said dissolving section; a water supply channel for guiding the water, said water supply channel including: a first supply channel for guiding the water into said dissolving section; and a second supply channel for guiding the water around said dissolving section so that the water does not pass through said dissolving section; a gas-dissolved water discharge channel for guiding the gas-dissolved water from said dissolving section, said second supply channel communicating with said gas-dissolved water discharge channel so that the water that does not pass through said dissolving section flows into the gas-dissolved water to thereby dilute the gas-dissolved water; a flow rate regulator arranged in said water supply channel, for regulating a flow of the water guided through said water supply channel; a dissolved solution gas concentration meter for measuring a solution gas concentration of the gas-dissolved water in said gas-dissolved water discharge channel; and a controller for controlling said flow rate regulator based on the solution gas concentration measured by said dissolved solution gas concentration meter.
