PROBLEM TO BE SOLVED: To provide a gas-dissolved water supplying apparatus with variation of the flowing rate of oxygen-enriched air due to variation of the surrounding temperature controlled.SOLUTION: The gas-dissolved water supplying apparatus causes a negative pressure generated in the water flow in a water pipe 1 to act on an oxygen-enriching means 3 through introduction piping 4 to generate oxygen-enriched air, introduces the oxygen-enriched air generated by the oxygen-enriching means 3 from the introduction piping 4 into the water pipe 1, dissolves the introduced oxygen-enriched air in water in a dissolving tank 5 to generate gas-dissolved water and discharges the gas-dissolved water from a discharge outlet 7. The oxygen-enriching means 3 is provided with a temperature detecting means 32 for detecting the temperature of an oxygen-enriching membrane 31 or the temperature of the atmosphere near the oxygen-enriching membrane 31 and a heating means 33 for heating the oxygen-enriching membrane 31 or the atmosphere near the oxygen-enriching membrane 31, and the oxygen-enriching membrane 31 or the atmosphere near the oxygen-enriching membrane 31 is heated by the heating means 33 according to a temperature detected by the temperature detecting means 32 so that the temperature of the oxygen-enriching membrane 31 of the oxygen-enriching means 3 or that of the atmosphere near the oxygen-enriching membrane 31 is kept at a predetermined temperature.COPYRIGHT: (C)2010,JPO&INPIT【課題】環境温度の変動による酸素富化空気の流量のバラツキを抑制した気体溶解水供給装置を提供する。【解決手段】通水管1の水流で発生する負圧を導入配管4から酸素富化手段3に作用させて酸素富化手段3で生成された酸素富化空気を導入配管4から通水管1に導入し、導入された酸素富化空気を溶解タンク5で水に溶解して気体溶解水を生成しこれを吐出口7から吐出する気体溶解水供給装置であって、前記酸素富化手段3には、酸素富化膜31の温度またはその近傍の雰囲気温度を検知する温度検知手段32と、酸素富化膜31またはその近傍の雰囲気を加熱する加熱手段33が設けられており、酸素富化手段3の酸素富化膜31の温度またはその近傍の雰囲気温度が予め設定した温度に保持されるように温度検知手段32で検知した温度に応じて酸素富化膜31またはその近傍の雰囲気を加熱手段33で加熱する。【選択図】図1
