主权项

1. A urinal with a sanitation device, comprising:
a bowl portion including a standing wall portion facing a user and a bottom surface portion that guides urine received by the standing wall portion to a drain hole; a trap unit, to which a chemical agent capable of being dissolved in urine flowing in from the bowl portion and capable of inhibiting generation of an ammonia smell and urine scale from urine is supplied, that retains urine containing the chemical agent to form a water seal, and that communicates with a drain tube; a liquid agent ejection unit for ejecting to the urinal a first liquid agent containing the chemical agent, or a second liquid agent in which the chemical agent disposed in the trap unit is dissolved; and a control unit for controlling the liquid agent ejection unit, wherein the control unit performs a bowl portion sterilization mode in which the liquid agent ejection unit is controlled so that the first liquid agent is ejected to the bowl portion at a predetermined timing, and a gradual dissolution mode in which the liquid agent ejection unit is controlled so that the second liquid agent is ejected to the trap unit at a predetermined timing in different forms from the bowl portion sterilization mode in such a manner that an amount of the second liquid agent attached to the bowl portion is smaller than an amount of the first liquid agent attached to the bowl portion in the bowl portion sterilization mode.
