Abstract
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. The enlarged part is enlarged on an upper side of the ascending flow channel. An upstream end of a top surface of the enlarged part is located below a highest reachable position of a bottom surface of the ascending flow channel.
