<p>A water supply pipe (10) with a flush control valve V<SUB>1</SUB> is connected to a rim (3) of a toilet body (1) of a hygienic western-style toilet facility that has an ejector for sucking and discharging air from and to a water discharge channel and in which odor and soil water are not supplied to a toilet bowl at the time of flushing. A branch pipe (11) is branched from that part of the water supply pipe (10) which is on the upstream side of the cleaning control valve V<SUB>1</SUB>, and the branch pipe (11) is connected to the ejector (20) through a U-shape tube (12) and an ejector water supply valve V<SUB>2</SUB>. The water discharge opening of the ejector (20) is connected to a second water discharge channel (7) through piping (13). An air suction opening (20a) provided at a throat section of the ejector (20) is connected to one end of a negative pressure transmission channel (21). The other end of the negative pressure transmission channel (21) is connected to the upper end (5a) of a rising section of a first water discharge channel (5).</p> |
