TOILET DEVICE

To increase the degree of freedom in an installation position of a bubble generating structure while obtaining high cleaning performance by arranging bubbles generated in the water by the bubble generating structure as nanobubbles so that they almost do not disappear during their movement to the discharge section.SOLUTION: A toilet device comprises a nanobubble generating structure 40 which is installed in a water channel 27 outside or inside the toilet device and generates nanobubbles and a discharge section 13 which discharges water containing the nanobubbles to a target to be cleaned. The nanobubble generating structure preferably comprises a venturi passageway including an inlet section, a restricting section and an outlet section, wherein the restricting section comprises a hole having a polygonal cross-section and the inlet section comprises a pyramidal inner surface having a polygonal cross-section that reduces in diameter according to the flow direction and connects to the restricting section. Each polygonal shape is preferably triangular, quadrangular, pentagonal or hexagonal.SELECTED DRAWING: Figure 1 【課題】気泡発生構造で水中に発生する気泡をナノバブルとすることにより吐出部までの移動中にほとんど消滅しないようにして、高い洗浄能力を得るとともに、気泡発生構造の設置位置の自由度を高める。【解決手段】トイレ装置は、トイレ装置の外部又は内部の水路２７に設けられた、ナノバブルを発生させるナノバブル発生構造４０と、前記ナノバブルを含む水を洗浄対象に吐出する吐出部１３とを含む。ナノバブル発生構造は、流入部と絞り部と流出部とを含むベンチュリー通路を備え、絞り部は断面が多角形の穴からなり、流入部は流れ方向に従い縮径して絞り部に接続する断面が多角形の角錐内面からなるものが好ましい。各多角形は、三角形、四角形、五角形又は六角形が好ましい。【選択図】図１
