周面に洗浄水を吐水して旋回流を形成するリム吐水部と、貯水タンクに貯水された洗浄水
をリム吐水部へ導くリム導水路と、を備えた便器本体と、を有し、リム導水路は、貯水タンクの排水口と接続し下方へと延びる下向導水路と、この下向導水路と繋がる屈曲導水路と、この屈曲導水路と繋がり横方向へ延び吐水部と連通する横向導水路とから構成され、横向導水路には、リム吐水部の出口の合計断面積よりも小さい通水断面積を有する縮径部が形成されていることを特徴としている。
このように構成された本発明においては、貯水タンクの給水流量が大きいほど導水路の
通水断面積が小さくなるように縮径部が横向導水路に設けられることにより、便器本体が
求める給水流量より大きい不適合の給水流量を生じさせる貯水タンクが便器本体に取付け

なく、便器洗浄のための適切な給水流量の洗浄水をボウル部へ供給することができる。
よって、ボウル部のリム部の内周面がオーバーハング形状又は略鉛直方向に立ち上がるように形成されている便器において、リム吐水部から吐水される洗浄水の給水流量が増大されることにより、リム部を旋回する洗浄水がリム部を越えて便器外に溢れ出すことを防止することができる。
また、便器本体が求める給水流量より小さい不適合の給水流量を生じさせる貯水タンクが便器本体に取り付けられた場合でも、各吐水口から出てくる洗浄水の分配比や洗浄水の流速を変化させることなく、便器洗浄のための適切な給水流量の洗浄水をボウル部へ供給することができる。
よって、リム吐水部から吐水される洗浄水の給水流量が減少されることにより、リム部を旋回する洗浄水の勢いが弱くなり、ボウル部内を十分に洗浄できなくなることを防止することができる。
In order to achieve the above object, the present invention is a flush toilet that cleans a toilet and discharges filth, and is installed on the rear upper surface of the toilet body, and opens and closes a drain outlet to the toilet body. A water storage tank, a bowl-shaped filth receiving surface, and a rim portion formed on the upper edge portion so that its inner peripheral surface rises in an overhang shape or in a substantially vertical direction, , A drainage channel connected to the lower part of the bowl part to discharge filth, a rim water discharge part that forms a swirling flow by discharging cleaning water to the inner peripheral surface of the rim part, and a wash stored in the water storage tank A rim conduit having a rim conduit for guiding water to the rim spout, and the rim conduit is connected to the drain of the water storage tank and extends downward, and the downward conduit The bent waterway that is connected and the side that is connected to this bent waterway It is composed of a lateral waterway that extends in the direction and communicates with the water discharge part, and the horizontal waterway has a reduced diameter part that has a water flow cross-sectional area smaller than the total cross-sectional area of the outlet of the rim water discharge part. It is a feature.
In the present invention configured as described above, the water supply flow rate required by the toilet body is obtained by providing the reduced diameter portion in the lateral water conduit so that the water flow cross-sectional area of the water conduit becomes smaller as the water supply flow rate of the water storage tank increases. Even when a water storage tank that generates a larger non-conforming water supply flow is attached to the toilet body, it is suitable for toilet flushing without changing the distribution ratio of wash water coming out of each spout and the flow rate of wash water. Washing water with a suitable water supply flow rate can be supplied to the bowl portion.
Therefore, in the toilet bowl in which the inner peripheral surface of the rim portion of the bowl portion is formed in an overhang shape or rises in a substantially vertical direction, the supply flow rate of the wash water discharged from the rim water discharge portion is increased. It is possible to prevent the wash water that swivels around the rim from overflowing outside the toilet.
In addition, even when a water storage tank that generates a non-conforming water flow rate smaller than the water supply flow rate required by the toilet bowl is attached to the toilet body, the distribution ratio of the wash water coming out from each outlet and the flow rate of the wash water must be changed. In addition, it is possible to supply the bowl portion with cleaning water having an appropriate supply flow rate for cleaning the toilet bowl.
Therefore, by reducing the water supply flow rate of the cleaning water discharged from the rim water spouting portion, the momentum of the cleaning water turning around the rim portion is weakened, and it is possible to prevent the inside of the bowl portion from being sufficiently washed.
