PROBLEM TO BE SOLVED: To obtain sufficient massage effects during bathing.SOLUTION: A microbubble injection system 100 configured so as to be capable of injecting microbubbles generated by a microbubble generation device 2 into hot water W to supply the hot water to a bathtub BT comprises: a hydrogen oxygen generation device 1 that performs electrolysis on liquid to be processed to generate mixture gas G at least including hydrogen and oxygen and supplies the generated mixture gas G to the microbubble generation device 2 and a controller 3 for controlling operation of both devices 1, 2. The microbubble generation device 2 is configured so as to be capable of generating microbubbles by making air bubbles from the mixture gas G. The controller 3 controls the hydrogen oxygen generation device 1 to make the hydrogen oxygen generation device generate mixture gas G to be used for generating microbubbles to be injected into hot water W by the microbubble generation device 2 as well as controls the microbubble generation device 2 to make the microbubble generation device generate microbubbles before injecting the microbubbles into hot-water W collected from the bathtub BT.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】入浴中に十分なマッサージ効果を得る。【解決手段】マイクロバブル発生装置2によって発生させたマイクロバブルを湯Wに注入して浴槽BTに供給可能に構成されたマイクロバブル注入システム100であって、被処理液を電気分解して水素および酸素を少なくとも含む混合気体G体を生成し、生成した混合気体Gをマイクロバブル発生装置2に給気する水素酸素生成装置1と、両装置1,2の動作を制御する制御装置3とを備え、マイクロバブル発生装置2は、混合気体Gを気泡化することでマイクロバブルを発生可能に構成され、制御装置3は、水素酸素生成装置1を制御してマイクロバブル発生装置2が湯Wに注入するマイクロバブルの発生に用いる混合気体Gを生成させると共に、マイクロバブル発生装置2を制御してマイクロバブルを発生させて浴槽BTから回収した湯Wにマイクロバブルを注入させる。【選択図】図1
