PROBLEM TO BE SOLVED: To provide a mist sprayer that causes high-temperature and high-humidity mist to float when a bathroom is used as mist sauna, and can improve washing effect by accelerating heating of a wall surface with mist of a washing liquid when the bathroom is washed.SOLUTION: A mist sprayer includes a mist sauna nozzle 10 for spraying mist of hot water into the air with such a particle diameter as to easily float in the air and a bathroom washing nozzle 4 for spraying mist of a washing liquid with such a particle diameter as to be hard to float in the air. In the bathroom washing nozzle 4, the washing liquid flowing into a nozzle body 63 is turned into a swirling flow and flows into an injection hole 60a through a tapered part 60c. The washing liquid flowing thereinto is turned into micronized water droplets by colliding against the inner peripheral surface of the injection hole 60a while swirling, and is injected from a nozzle hole 60b as water droplets. In the bathroom washing nozzle 4, the minimum size of a narrow part which the washing liquid passes through is 0.5 mm or more.COPYRIGHT: (C)2014,JPO&INPIT【課題】ミストサウナ時に高温多湿のミストを浮遊させるものでありながら、浴室洗浄時には洗浄液のミストにより壁面の加熱が促進されて洗浄効果を高めることができるミスト噴霧装置を提供する。【解決手段】空中に浮遊しやすい程度の粒子径の湯水のミストを噴霧するミストサウナ用ノズル10と、空中に浮遊しやすい程度の小さい粒子径の洗浄液のミストを噴霧する浴室洗浄用ノズル4とを備える。浴室洗浄用ノズル4は、ノズル本体63内に流入する洗浄液が、旋回流となって、テーパ部60cを経由して噴射穴60a内に流入し、この流入する洗浄液が、噴射穴60aの内周面に旋回しながら衝突して水滴が微細化され、噴口60bから水滴となって噴射される。浴室洗浄用ノズル4において洗浄液が通過する最小狭部寸法が0.5mm以上とされる。【選択図】図1
