TOILET BOWL FLUSHING DEVICE AND TOILET BOWL DEVICE INCLUDING THE SAME
PROBLEM TO BE SOLVED: To provide a washing water supplying device capable of preventing tilting of a valve body.SOLUTION: The washing water supplying device supplying washing water to a toilet bowl comprises: a water inlet portion forming a primary side channel; a water outlet portion crossing the water inlet portion and forming a secondary side channel; a communication portion protruding into the water inlet portion from an inner wall surface of the water inlet portion connected to the water outlet portion and making the inside of the water inlet portion communicate with the inside of the water outlet portion; and a pilot type diaphragm valve opening and closing a communication port which is an entrance of the communication portion. The diaphragm valve includes: a valve body; a pressure chamber portion forming a pressure chamber at an opposite side to the communication port with the valve body placed in between; a communication channel formed in the valve body and making the water inlet portion communicate with the pressure chamber portion; a pilot channel making pressure chamber portion communicate with the water outlet portion; and a control valve opening and closing the pilot channel. In the water inlet portion, a connection port in which the diaphragm valve is provided is opened at a position facing the inner wall surface in which the communication portion is formed. The communication portion protrudes up to the outside of an inside edge of the connection port.SELECTED DRAWING: Figure 2
【課題】弁本体を傾きにくくすることが可能な洗浄水供給装置を提供する。【解決手段】便器に洗浄水を供給する洗浄水供給装置であって、一次側流路を形成する入水部と、この入水部に交差して二次側流路を形成する出水部と、入水部の出水部と接続される内壁面から入水部内に突出し、入水部内と出水部内とを連通する連通部と、この連通部の入口である連通口を開閉するパイロット式ダイヤフラム弁と、を備え、ダイヤフラム弁は、弁本体と、この弁本体を挟んで連通口と逆側に圧力室を形成する圧力室部と、弁本体に形成され入水部と圧力室部とを連通する連通流路と、圧力室部と出水部とを連通するパイロット流路と、このパイロット流路を開閉する制御弁と、を有し、入水部は連通部が形成される内壁面と対向する位置にダイヤフラム弁が設けられる接続口が開口され、連通部は接続口の内側端より外側にまで突出する洗浄水供給装置である。【選択図】 図２
