Abstract: A urinal for receiving and discharging urine having a bowl portion having a bowl surface for receiving urine; a spouting device disposed on a top portion of the bowl portion for spouting flush water onto the bowl surface; and a discharge trap portion, communicating with a discharge port disposed on a bottom portion of the bowl portion, for discharging flush water and forming a water seal on a downstream side of the bowl portion. The discharge trap includes a descending conduit, a horizontal conduit, and an ascending conduit, and a cross section perpendicular to a discharging direction of either the horizontal conduit or the ascending conduit on the discharge trap portion is formed so that an inner side of the urinal from a center of the cross section has a smaller cross sectional area than an outer side of the urinal from the center of the cross section.

Abstract: A urinal having the bowl surface formed by only the front face portion in an upper region which does not have any forwardly projecting plate-like side walls at opposite sides thereof as in the conventional urinal. Flush water cleans a wider part of the bowl surface than in the prior art as well as reduce an area of the bowl surface that is not cleaned and provide an improved cleanliness and sanitation of the bowl surface. The urinal includes: a bowl surface being arranged so as to situate between a line segment connecting the left and right side edges and an arcuate segment of a circle having a diameter corresponding to the line segment, as viewed in the horizontal section through the flush water discharging device.

Abstract: A urinal capable of constraining the occurrence of uric scale in a discharge horizontal branch pipe even if flush water volume has been reduced by water conservation is disclosed. A urinal includes a control unit with a main flush mode M0; a first equipment flushing mode M1 in which a portion of flush water flushes the upstream side of a connecting portion; and a second equipment flushing mode M2 in which a portion of flush water flushes the upstream side of the connecting portion. At least one of either the first mode M1 or the second mode M2, the value of the discharge volume or the discharge instantaneous flow volume discharged is set to be equal to or greater than the value of the discharge volume or the discharge instantaneous flow volume in the main flush mode.
