PROBLEM TO BE SOLVED: To provide an installation structure of a gas dissolving apparatus, which can sufficiently and easily achieve protection against water leakage at a connection part between the gas dissolving apparatus and a bathtub.SOLUTION: In the gas dissolving apparatus 1, a dissolving tank 2 and a pump 3 are vertically arranged to be fixed to a fixing device 4 for bathtub installation. The dissolving tank is connected to a discharge side of the pump, suction piping 24 is connected to a suction side of the pump, and the suction piping extends toward a suction port 25 communicating with the inside of the bathtub. An outflow piping 26 is connected to a discharge side of the dissolving tank and the outflow piping extends toward a discharge port 27 communicating with the inside of the bathtub. A waterproof pan 36 is arranged at the lower side of a first connecting part 32 between the suction piping and the suction side of the pump, and of a second connection part 35 between the outflow piping and the suction side of the dissolving tank. The waterproof pan is fixed to the fixing device.COPYRIGHT: (C)2012,JPO&INPIT【課題】気体溶解装置と浴槽の接続部における水漏れに対する防護を十分にかつ簡便に実現することのできる気体溶解装置の設置構造を提供すること。【解決手段】溶解タンク2とポンプ3が縦列配置されて浴室設置用の固定装置4に固定され、溶解タンクは、ポンプの吐出側に接続され、ポンプの吸い込み側に吸い込み配管24が接続され、吸い込み配管は、浴槽内に連通する吸い込み口25に向かって延び、溶解タンクの吐出側に流出配管26が接続され、流出配管は、浴槽内に連通する吐出口27に向かって延びている気体溶解装置1において、吸い込み配管とポンプの吸い込み側との第1接続部32と、流出配管と溶解タンクの吐出側との第2接続部35との下側に防水パン36が設けられ、防水パンは固定装置に固定されている。【選択図】図1
