The washing water that has flowed into the bowl bottom drainage part 12 flows into the trap part 14 through the opening 181b provided in the lid member main body 181.
[0027]
Part of the washing water that has flowed into the trap portion 14 collides with the upper surface of the guide member 313, the flow direction is changed, and flows into the medicine placement portion 31 through the inflow hole 312. The washing water that has flowed into the drug placement unit 31 dissolves the solid drug 17 and then is discharged to the trap unit 14 through the outflow hole 311. The washing water discharged to the trap unit 14 cleans the urine stones stuck to the trap unit 14.
[0028]
When a predetermined time elapses, the solid drug 17 is dissolved and its life is exhausted. Therefore, it is necessary to replace the solid drug 17 with a new solid drug 17.
