PROBLEM TO BE SOLVED: To provide a whirlpool bath apparatus capable of facilitating collection of light dirt floating on a surface layer of bathtub water and dirt stuck to a bathtub wall surface.SOLUTION: A whirlpool bath apparatus 1 that generates whirlpool in a bathtub 11 to stimulate an affected part, includes: a pump 14 for circulating water in the bathtub 11 and a water suction port 17 provided in the bathtub 11 and through which the pump 14 sucks the water in the bathtub 11. The bathtub 11 includes a first tank 111 in which the affected part is placed, and a second tank 112 connected to the first tank 111 and having a volume smaller than that of the first tank 111. Only the second tank 112 out of the first tank 111 and the second tank 112 includes the water suction port 17, or both of the first tank 111 and the second tank 112 include water suction ports, where the water suction port of the second tank 112 is larger than the water suction port of the first tank 111.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2018,JPO&INPIT【課題】浴槽水の表層に浮遊する軽いごみ及び浴槽壁面にへばり付いたごみを回収し易くできる渦流浴装置を提供する。【解決手段】浴槽11内に渦流を生じさせて患部を刺激する渦流浴装置1は、浴槽11内の水を循環させるポンプ14と、浴槽11に設けられて、ポンプ14が浴槽11内の水を吸うための吸水口17と、を備える。浴槽11は、前記患部が入れられる第1槽111と、第1槽111と繋がるとともに第1槽111より体積の小さい第2槽112と、を有する。第1槽111と第2槽112とのうち、第2槽111にのみ、吸水口17が設けられているか、或いは、吸水口が第1槽111及び第2槽112の両方に設けられるとともに、第2槽112の吸水口が第1槽112の吸水口よりも大きい。【選択図】図4
