Summary: | To certainly cause siphonage to occur while suppressing dirt clogging.SOLUTION: A water closet according to an embodiment has a bowl part, a water discharge part, a drain trap part, and a drain socket. The bowl part has a dirt receiving surface and a rim part. The water discharge part discharges washing water into the bowl part. The drain trap part is connected to a bottom of the bowl part and discharges the dirt in the bowl part. The drain socket is connected to the drain trap part on an upstream side and an exhaust port on a floor surface on a downstream side and has a rear R part to change a channel so that the washing water from above flows forward, a front R part that is disposed downstream of the rear R part and changes the channel so that the washing water from backward flows downward, and a water reservoir part to store a portion of the washing water at the channel from the rear R part to the front R part. The drain socket has a narrow part having the minimum cross-sectional area at the rear R part at an area excluding the uppermost stream end and the lowermost stream end of the rear R part.SELECTED DRAWING: Figure 3
【課題】汚物詰まりを抑えながらサイホン作用を確実に発生させること。【解決手段】実施形態に係る水洗大便器は、ボウル部と、吐水部と、排水トラップ部と、排水ソケットとを備える。ボウル部は、汚物受け面と、リム部とを有する。吐水部は、ボウル部内へと洗浄水を吐出する。排水トラップ部は、ボウル部の底部に接続され、ボウル部内の汚物を排出する。排水ソケットは、上流側が排水トラップ部に接続され、下流側が床面の排水口に接続される排水ソケットであって、上方からの洗浄水が前方へ向かうように流路を変更する後側R部と、後側R部よりも下流に設けられ、後方からの洗浄水が下方へ向かうように流路を変更する前側R部と、後側R部から前側R部までの流路において洗浄水の一部を貯留する水溜部とを有する。排水ソケットは、後側R部の最上流端および最下流端を除いた領域に、後側R部において断面積が最小となる狭小部を有する。【選択図】図3 |
