To provide a fine bubble generation device with a simple structure capable of sufficiently securing the flow rate of flowing hot water.SOLUTION: A fine bubble generation device 1 has a cylindrical case member 10 comprising an inner cylinder part 13, and plural circular disc-like members 20 disposed by overlapping coaxially with respect to a center axis CA of the inner cylinder part 13. The circular disc-like member 20 has a through-hole passing hot water in a plate thickness direction, and the through-hole has plural inclined through-holes 21f and toric annular recesses 21d disposed in the plate thickness direction. The inclined through-hole 21f is formed as a hole inclined to a top face 21e by gradually rotating in the same direction around the center axis CA as plural fan-shaped openings disposed at equal intervals in a circumferential direction are directed downward on the top face 21e of the circular disc-like member 20. Besides, the annular recesses 21d are formed as toric holes opening on a lower face 21c by combining the lower side openings of the inclined through-holes 21f. The respective through-holes of plural circular disc-like members 20 communicate with each other to form a part of the flow path from a supply port 11 to a discharge port 12.SELECTED DRAWING: Figure 4
【課題】構造が簡潔で流れる湯水の流量を充分確保できる微小気泡発生装置を提供する。【解決手段】微小気泡発生装置１は、内筒部１３を備えた円筒状のケース部材１０と、内筒部１３の中心軸ＣＡに対して同軸に重ね合わせて配置された複数の円板状部材２０と、を有する。円板状部材２０は板厚方向に湯水を通す貫通孔を有し、該貫通孔は板厚方向に配置された複数の傾斜貫通孔２１ｆと円環状の環状凹部２１ｄとを有する。傾斜貫通孔２１ｆは円板状部材２０の上面２１ｅにおいて周方向に等間隔で配置された複数の扇形状の開口が下方に向かうにつれて中心軸ＣＡを中心に同一方向に徐々に回転して上面２１ｅに対して傾斜した孔として形成され、環状凹部２１ｄは複数の傾斜貫通孔２１ｆの下側の開口を連結して下面２１ｃに開口する円環状の孔として形成される。複数の円板状部材２０の各貫通孔は連通して供給口１１から吐出口１２までの流路の一部を形成している。【選択図】図４
