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 M; a first equipment flushing mode Min which a portion of flush water flushes the upstream side of a connecting portion; and a second equipment flushing mode Min which a portion of flush water flushes the upstream side of the connecting portion. At least one of either the first mode Mor the second mode M, 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.
