Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a jet bath with a steam jetting nozzle for sauna and to improve the jetting power of water jet without converting motor power. SOLUTION: A jet bath is provided with a steam-jetting nozzle for sauna and a water jet exhausting device fixed to the jet bath is provided with an inner cylinder 36 inside of an outer cylinder 35. Then, a fast flow 33 is made to flow through the inner cylinder and a slow flow 34 is made to flow between the inner cylinder and the outer cylinder to constitute a two-layer flow. A reduced diameter part 39 is formed at the exit of the fast flow to accelerate and the diameter of the exit of the part 39 is expanded to generate negative pressure. The slow flow 34 and air are inspired by this negative pressure to be joined with the fast flow 33 to exhaust jet including fine bubbles. |
