PROBLEM TO BE SOLVED: To provide a bathtub apparatus dissolving hydrogen gas in a bathtub while retaining the concentration of hydrogen gas in the bathroom to such a level as causing no risk of explosion.SOLUTION: This hydrogen gas bubble bathtub apparatus is provided with: a hydrogen gas supply device 1 supplying hydrogen gas to the bathtub 8 a first hydrogen gas container 2 a second hydrogen gas container 3 filled with hydrogen gas to be supplied to the bathtub at an amount enough for a single bathing a first hydrogen gas supply pipe 4, or a pipe for supplying the hydrogen gas from the first hydrogen gas container to the second hydrogen gas container and having a solenoid valve 5 in a pipe line and a second hydrogen gas supply pipe 6, or a pipe for supplying the hydrogen gas to be supplied to the bathtub by the amount for a single bathing during bathing from the first hydrogen gas container to the second hydrogen gas container. Only the hydrogen gas supplied to the second hydrogen gas container is supplied to the bathtub inside by the hydrogen gas supply means and dissolved in the bathwater in the bathtub and the concentration of the hydrogen gas in the bathtub is adjusted to 4% or less.COPYRIGHT: (C)2008,JPO&INPIT【課題】浴室内を爆発の危険がない水素ガス濃度に維持しつつ、浴槽内に水素ガスを溶解させた浴槽装置を提供する。【解決手段】浴槽8に供給する水素ガス供給手段1、第1の水素ガス容器2、1回に浴槽に供給する量の水素ガスを充填する第2の水素ガス容器3、第1の水素ガス容器から第2の水素ガス容器に水素ガスを供給する管であって管路中に電磁弁5が設けられた第1の水素ガス供給配管4、第2の水素ガス容器から水素ガス供給手段に水素ガスを供給する管であって管路中に電磁弁7が設けられた第2の水素ガス供給配管6とを備え、使用時に1回に浴槽内の浴湯中に供給する量の水素ガスが前記第1の水素ガス容器から前記第2の水素ガス容器に供給され、前記第2の水素ガス容器に供給された水素ガスのみが、前記水素ガス供給手段により浴槽内に供給され浴槽内の浴湯中に溶解し、浴室内の水素ガス濃度が4%以下に調節される水素ガス気泡浴槽装置。【選択図】図1
