The object of the present invention is to provide a washdown flush toilet which can maintain effective waste discharging performance even with a relatively smaller amount of flush water.The present invention is a washdown flush toilet including: a bowl part configured to receive waste, and a water discharge trap conduit connected to a lower portion of the bowl part. The water discharge trap conduit includes: an inlet pipe part whose one end is continuous or connected to the lower portion of the bowl part; a trap ascending pipe part whose one end is continuous or connected to the other end of the inlet pipe part and which forms an ascending flow channel; and a trap descending pipe part whose one end is continuous or connected to the other end of the trap ascending pipe part and which forms a descending flow channel. With regard to a cross section perpendicular to a flow direction of the ascending flow channel, a portion on a downstream side of the ascending flow channel is provided with an enlarged part which has a cross section area larger than that on an upstream side of the ascending flow channel. A downstream end of the ascending flow channel and/or an upstream side of the descending flow channel is provided with a shrunk part which has a cross section area smaller than that on the upstream side of the ascending flow channel.
本发明提供一种冲落式冲水大便器，即使清洗水量相对较少也能够维持有效的污物排出性能。具体而言，本发明的冲落式冲水大便器具备承接污物的盆部及连接于盆部下方部的排水弯管管路。排水弯管管路具有：入口管部，其一端侧与盆部的下方部连续或连接；弯管上升管部，其一端侧与入口管部的另一端侧连续或连接而形成上升流路；以及弯管下降管部，其一端侧与弯管上升管部的另一端侧连续或连接而形成下降流路。在与上升流路的流路方向垂直的截面中，在上升流路的下游侧的一部分形成有扩大部，其流路截面积比上升流路的上游侧的流路截面积大。在上升流路的下游端及/或下降流路的上游侧形成有缩小部，其流路截面积比上升流路的上游侧的流路截面积小。
