<p>PROBLEM TO BE SOLVED: To provide a toilet bowl device which simplifies a configuration in comparison with the case where a power source which allows a functional liquid to flow into a supply port is provided, and is capable of adjusting the timing or the quantity of the functional liquid to be supplied.SOLUTION: The toilet bowl device comprises a flow passage 10 for discharging water from a discharge port into a bowl, and a supply path 20 for supplying a functional liquid 30 to water flowing in the flow passage 10. The flow passage 10 is confluent with the supply path 20 in a narrowed part 13 which includes an opening 17 on the circumferential surface thereof. The supply path 20 includes a liquid reservoir 21 formed from a sealed container, and a connection part 25 for connecting the liquid reservoir 21 to the flow passage 10. The connection part 25 includes an elastic member 27 provided with a slit-shaped through hole 28 which is opened/closed in accordance with a pressure change in the narrowed part 13. The through hole 28 is disposed within the opening 17 as a supply port 26. An air supply path 50 which allows air to flow into the flow passage 10 is provided while being confluent in the narrowed part 13 with a gap between an outer surface of the elastic member 27 in the through hole 28 and an edge of the opening 17 as an inflow port 51. In the air supply path 50, an on-off valve 52 is provided which is capable of freely adjusting an opening amount.</p> |
