HAYASHI NOBUHIRO / KITAURA HIDEKAZU / SHIMUTA AKIHIRO / KUROISHI MASAHIRO

To provide a washing water tank device capable of suppressing the flooding of a power generation part of an electric generator due to the splash of washing water when the washing water flowing out of an atmosphere introduction port into a water storage tank during opening a valve element of a vacuum breaker lands on a landing position in the water storage tank, and provide water closet equipment including the same.SOLUTION: A washing water tank device 4 includes a drain valve device 18 including a drain valve 18a for opening/closing a drain port 16a of a water storage tank 16, an electric generator 22 including a power generation part 22b for converting the rotating motion of a water turbine 22a which is rotated by a water flow into electric power, and a water supply control device 12 including a solenoid valve 14 to be operated by the electric power generated by the electric generator, the water supply control device including a vacuum breaker 32, the electric generator being arranged on the opposite side to a landing position Q2 where washing water W2 flowing out of the atmosphere introduction port of the vacuum breaker lands in the water storage tank, across an outline part 18b of the drain valve device.SELECTED DRAWING: Figure 2

【課題】バキュームブレーカの弁体の開弁時に大気導入口から貯水タンク内に流出した洗浄水が貯水タンク内の着水位置に着水した際、その洗浄水の飛散による発電機の発電部の被水を抑制することができる洗浄水タンク装置、及び、それを備えた水洗便器装置を提供する。【解決手段】本発明の洗浄水タンク装置４は、貯水タンク１６の排水口１６ａを開閉する排水弁１８ａを備えた排水弁装置１８と、水流により回転する水車２２ａの回転運動を電力に変換する発電部２２ｂを備えた発電機２２と、この発電機によって生成された電力により作動する電磁弁１４を備えた給水制御装置１２と、を有し、この給水制御装置は、バキュームブレーカ３２を備え、発電機は、バキュームブレーカの大気導入口から流出した洗浄水Ｗ２が貯水タンク内に着水する着水位置Ｑ２に対して排水弁装置の外郭部１８ｂを挟んで逆側に配置されている。【選択図】図２
