BATHTUB WASHING SYSTEM

To provide a bathtub washing system capable of washing off in a rinsing step washing water entering between a bathtub flange part and an outer peripheral edge of a lower surface of a bathtub lid in a washing step.SOLUTION: A bathtub washing system 1 performs bathtub washing operation that has: a washing step which mounts a bathtub lid 22 on a bathtub flange part 21 and jets washing water mixing hot water and detergent to an inner wall surface of a bathtub 2 from a washing nozzle 32 provided in the bathtub 2; and a rinsing step which jets hot water after the washing step and washes off the washing water. On an outer periphery edge 23 of a lower surface of the bathtub lid 22 facing the bathtub flange part 21 or an upper surface of the bathtub flange part 21, a projection 5 which has a prescribed height h and forms a gap d which makes it easy for the hot water in the rinsing step to enter between the bathtub flange part 21 and the outer periphery edge 23 of the lower surface of the bathtub lid 22 when the bathtub lid 22 is placed on the bathtub flange part 21.SELECTED DRAWING: Figure 3 【課題】洗浄工程で浴槽フランジ部と浴槽蓋下面の外周縁との間に入り込んだ洗浄水をすすぎ工程で洗い流すことを可能とする浴槽洗浄システムを提供する。【解決手段】浴槽洗浄システム１は、浴槽フランジ部２１に浴槽蓋２２を載置し、浴槽２内に設けた洗浄ノズル３２から浴槽２の内壁面に対して、湯水と洗剤とを混合した洗浄水を噴射する洗浄工程と、洗浄工程後に湯水を噴射して洗浄水を洗い流すすすぎ工程とを有する浴槽洗浄運転を実行する。浴槽フランジ部２１と対向する浴槽蓋２２下面の外周縁２３又は浴槽フランジ部２１の上面には、所定高さｈを有し、浴槽蓋２２を浴槽フランジ部２１に載置したときに浴槽フランジ部２１と浴槽蓋２２下面の外周縁２３との間にすすぎ工程の湯水を入り込みやすくする隙間ｄを形成する突部５を有する。【選択図】図３
