2. Description of the Related Art Conventionally, many flush toilet bowls are used with a detachable eye plate on the drain outlet for the purpose of preventing the backflow of a strange odor from the drain pipe and the invasion of harmful insects. This detachable eye plate is usually made of the same pottery as the urinal body, and sometimes the hand plate was slid and dropped during cleaning to damage a part of the eye plate. Therefore, recently, in order to prevent breakage of the eye plate, the eye plate made of melamine resin and the eye plate made of polybutylene terephthalate resin disclosed in Patent Document 1 are also used.
しかしながら、特許文献１のように目皿が樹脂からなり撥水性を有する場合は、洗浄水が目皿上面を通過する際に幅の小さな流れになってしまい、目皿上面において洗浄されない部分（不洗浄部）が生じてしまうという問題があった。また、最近は省エネ（節水）の需要から洗浄水量が従来のものより少量になってきており、このような問題が顕著に表れるようになってきている。 However, when the eye plate is made of resin and has water repellency as in Patent Document 1, the washing water becomes a small flow when passing through the upper surface of the eye plate, and the portion that is not washed on the upper surface of the eye plate (non-cleaning) There was a problem that the cleaning part) would occur. In recent years, the amount of washing water has become smaller than the conventional one due to the demand for energy saving (water saving), and such a problem is becoming apparent.

Hereinafter, with reference to FIG. 4, the flow of the cleaning water when the cleaning water is supplied to the urinal of the above embodiment will be described.
When the user performs a cleaning start operation on a water supply source such as a flash valve (not shown), the cleaning water is discharged from the water discharger 6 provided on the back surface 2 of the bowl 3, and the discharged water is It flows down along the back surface part 2 of 3. The washing water that travels along the back surface portion 2 then flows into the bottom surface portion 8. At that time, a part of the washing water flows into the gap between the eye plate 10 and the eye plate mounting part 13 (flow of arrow X), but collides with the rib 14 provided on the eye plate mounting part 13 and flows upward. (Flow of arrow Y). As a result, the cleaning water that has flowed into the gap between the eye plate 10 and the eye plate mounting portion 13 joins the cleaning water that passes through the upper surface of the eye plate 10. Thereafter, the washing water passes through the upper surface of the eye plate 10 and flows to the front side of the eye plate 10. Then, out of the gap between the eye plate 10 and the eye plate mounting portion 13, the water flows out from the front space where the rib 14 is not provided to the drain port 16.
それにより、吐水部６から吐水された洗浄水の多くは、目皿１０の上面を通過することとなり、目皿１０の上面全体を洗浄することができる。したがって、目皿１０上面において不洗浄部が生じにくくなる。 Thereby, most of the wash water discharged from the water discharger 6 passes through the upper surface of the eye plate 10, and the entire upper surface of the eye plate 10 can be cleaned. Therefore, the non-cleaning portion is less likely to occur on the upper surface of the eye plate 10.
なお、本実施形態において、洗浄水流出抑制手段としてリブ１４を示したが、本発明はこれに限定されず、洗浄水の流出を抑制するものであればよい。例えば、目皿と目皿載置部を接着させる面ファスナー等でも良い。 In the present embodiment, the ribs 14 are shown as the washing water outflow suppression means. However, the present invention is not limited to this, and any means may be used as long as the washing water outflow is suppressed. For example, a hook-and-loop fastener that bonds the eye plate and the eye plate mounting portion may be used.
