PROBLEM TO BE SOLVED: To provide a jet bath apparatus which generates jet flow that gives appropriate massage feeling on the shoulder and the hip of a person taking a bath while reducing the number of circulation pumps.SOLUTION: In the jet bath apparatus, a circulation flow path 32 is provided for circulating hot water within a bathtub 31 by means of a circulation pump P. The circulation flow path 32 is branched downstream of the circulation pump P. Jet nozzle apparatuses 1a and 1b are arranged respectively on end parts of branched paths 32a and 32b. The plurality of jet nozzle apparatuses 1a and 1b are arranged so that the former is above the latter. The branched paths 32a and 32b and/or the jet nozzle apparatuses 1a and 1b are configured such that jet flow volume from the lower jet nozzle apparatus 1b is larger than that from the upper jet nozzle apparatus 1a.COPYRIGHT: (C)2012,JPO&INPIT【課題】循環ポンプ数の削減を図りつつも、入浴者の肩と腰に対して最適なマッサージ感を与えることのできる噴流を発生することのできる噴流風呂装置を提供する。【解決手段】浴槽31内の湯を循環ポンプPにより循環させる循環流路32を設け、該循環流路32を循環ポンプPの下流側で分岐させ、各分岐路32a,32bの終端部に浴槽内へ湯を噴出する噴流ノズル装置1a,1bを設けるとともに、これら複数の噴流ノズル装置1a,1bを上下に配設し、上側の噴流ノズル装置1aよりも下側の噴流ノズル装置1bからの噴出流量が大きくなるように各分岐路32a,32b及び/又は各噴流ノズル装置1a,1bを構成する。【選択図】図1
