TOILET SEAT UNIT AND TOILET BOWL DEVICE

To provide a technique capable of suppressing occurrence of splash in achieving washing of a rear surface of a toilet seat.SOLUTION: A toilet seat unit comprises: a toilet seat 22 attached to a toilet bowl body; a plurality of discharge parts 50A, 50B capable of discharging washing fluid. The plurality of discharge parts 50A, 50B comprise: a first discharge part 50A capable of discharging the washing fluid to one side of the toilet seat 22 in a peripheral direction so as to flow along a rear face of the toilet seat 22; and a second discharge part 50B for discharging the washing fluid to the other side of the toilet seat 22 in the peripheral direction so as to flow along the rear face of the toilet seat. The toilet seat unit is configured to finish an operation in which the first discharge part 50A discharges the washing fluid so as to flow along the rear face, and then start an operation in which the second discharge part 50B discharges the washing fluid so as to flow along the rear face.SELECTED DRAWING: Figure 21 【課題】便座の裏面の洗浄を実現するにあたり、飛沫の発生を抑制できる技術を提供する。【解決手段】便器本体に取り付けられる便座２２と、洗浄液を吐出可能な複数の吐出部５０Ａ、５０Ｂと、を備える便座ユニットであって、複数の吐出部５０Ａ、５０Ｂには、便座２２の周方向の一方側に向けて便座２２の裏面を伝うように洗浄液を吐出可能な第１吐出部５０Ａと、便座２２の周方向の他方側に向けて裏面を伝うように洗浄液を吐出可能な第２吐出部５０Ｂと、が含まれ、便座ユニットは、裏面を伝うように第１吐出部５０Ａが洗浄液を吐出する動作を終了してから、裏面を伝うように第２吐出部５０Ｂが洗浄液を吐出する動作を開始するように構成される。【選択図】図２１
