た水洗式便器に関する。[Detailed Description of the Invention] <Industrial Application Field> The present invention provides a rim passageway in which a large number of water injection holes are formed protruding from the upper periphery of the bowl, and a hole is opened at the tip of the rim passageway. The present invention relates to a flush toilet in which the jet hole is connected to a water conduit formed on the back surface of the bowl through a jet communication hole, and the jet hole is opened from the tip of the water conduit to the entrance of the drainage channel.
＜従来の技術＞
従来、この種の水洗式便器として例えば実願昭
57−168184号明細書に記載せる如くリム通水路へ
供給された洗浄水の一部が射水孔から吐水されて

形成するものがある。<Conventional technology> Conventionally, this type of flush toilet has been developed by
As described in the specification of No. 57-168184, a part of the washing water supplied to the rim water passage is discharged from the water injection hole to wash the inner surface of the bowl, and the remaining washing water passes through the jet communication hole and the water conduit to the jet hole. There are toilet bowls that eject jet water from the toilet, causing a siphon effect in the drainage channel, causing the waste water and dirt in the bowl to be drained out of the toilet all at once, and then forming a water seal.
＜発明が解決しようとする課題＞
しかし乍ら、このような従来の水洗式便器では
用便時に汚物がボウル内面の封水部以外の乾燥面
に落下すると、この乾燥面に汚物が付着し、用便
後に洗浄水を１回流しただけでは完全に落ちず、
これが乾燥すると更に固着して非常に見苦しいと
共に臭気を発生するという問題がある。<Problems to be Solved by the Invention> However, in such conventional flush toilets, when filth falls onto the drying surface other than the water-sealing portion on the inner surface of the bowl, the filth adheres to this drying surface. Even if you flush water once after using the toilet, it won't completely come off.
When this dries, it becomes even more sticky, making it very unsightly and producing an odor.
そこで、用便中リム通水路に給水して射水孔か
ら吐水させることにより汚物の付着を防止するこ
とが考えられる。 Therefore, it is conceivable to prevent the adhesion of filth by supplying water to the rim passageway during use and discharging water from the water injection hole.
しかし上記従来のものでは用便中にリム通水路
へ給水すると洗浄水が射水孔に供給されるだけで
なくジエツト連絡孔を介して導水路にも供給さ
れ、ジエツト孔から洗浄と関係なく無駄に排水さ
れて不経済であるという問題がある。 However, with the above-mentioned conventional system, when water is supplied to the rim water passage during urination, the washing water is not only supplied to the water injection hole but also to the water conduit through the jet communication hole, and is wasted from the jet hole regardless of washing. There is a problem that it is wasteful and uneconomical.
本発明は斯る従来事情に鑑み、用便時にリム通
水路から射水孔だけに洗浄水を供給してボウル内
面全体にウオーターカーテンを形成することを目
的とする。 In view of the conventional situation, an object of the present invention is to form a water curtain on the entire inner surface of the bowl by supplying washing water only to the water injection hole from the rim passageway when using the bowl.

ようにする。 In this embodiment, a solenoid valve is used as the water film water supply valve b 1 , and a flush valve integrally equipped with a drive solenoid 10 is used as the toilet flushing water supply valve b 2. Both water supply valves b 1 and b 2 The operation of the toilet is controlled by a photoelectric sensor 11 placed inside the toilet.
The photoelectric sensor 11 opens the water film water supply valve b1 when the user approaches the toilet body A, and when the user leaves the toilet body A after defecating, the driving solenoid 10 is activated to clean the toilet. Open water supply valve b2 .

本体Ａの給水室a4よりリム通水路a3に供給され、
その下面に開穿した多数の射水孔１…からボウル
a1内面に吐水してウオーターカーテンを形成す
る。 Therefore, in such a flush toilet, the water film water supply valve b1 opens when defecating, and flush water with a small instantaneous flow rate is supplied from the water supply chamber a4 of the toilet body A to the rim water passage a3 . ,
Numerous water injection holes drilled on the bottom surface 1... to the bowl
a 1 Spray water on the inner surface to form a water curtain.
もしこの時、汚物が封水部７以外のボウルa1内
面に落ちたとしても付着することなく洗い流され
る。 At this time, even if dirt falls onto the inner surface of the bowl a 1 other than the water sealing part 7, it will be washed away without adhering to it.
また、この際、水膜用給水弁b1からリム通水路
a3に供給される洗浄水は瞬間流量が少ないために
ジエツト連絡孔６の周縁部１２を越えられず、そ
のほとんど全部が射水孔１…から吐水され、導水
路a6を介してジエツト孔２に流れることはない。 Also, at this time, connect the rim water passage from the water film water supply valve b 1.
Because the instantaneous flow rate of the cleaning water supplied to A 3 is small, it cannot cross the peripheral edge 12 of the jet communication hole 6, and almost all of it is discharged from the water injection holes 1 and flows through the water conduit A 6 to the jet hole 2. It never flows.
そして用便後に、便器洗浄用給水弁b2が開弁し

すると共に、導水路a6を介してジエツト孔２から
ジエツト水流が噴出し、屈曲した排水路a2内にサ
イホン現象を起こさせてボウルa1内の汚水・汚物
が便器Ａ外に完全に排出される。 After using the toilet, the water supply valve b 2 for flushing the toilet opens, and flush water with a large instantaneous flow rate is supplied to the rim water passage a 3 and is discharged from the numerous water injection holes 1 to the inner surface of the bowl a 1 . Jet water jets out from the jet hole 2 via the water conduit a6 , causing a siphon effect in the bent drainage channel a2, and the sewage and filth in the bowl a1 are completely discharged to the outside of the toilet bowl A.
更に本実施例の場合、上記ボウルa1の周壁には

にしている。 Furthermore, in the case of this embodiment, an odor intake port 13 is opened in the peripheral wall of the bowl a1 , and the odor intake port 13 is connected to an exhaust passage 15 to an exhaust port 14 provided on the rear side of the toilet bowl A.
A fan 16 connected to the exhaust port 14 is used to exhaust the odor inside the bowl a1 .
そしてこのフアン１６は前記光電センサー１１
と連動して用便中に作動するようにする。 This fan 16 is connected to the photoelectric sensor 11.
It works in conjunction with this so that it can be activated while using the toilet.
尚、前示実施例においては水膜用給水弁b1、便

便後便器洗浄用給水弁b2のスイツチをONさせる
ようにしても良い。 In the above-mentioned embodiment, the water film water supply valve b 1 , the toilet flushing water supply valve b 2 and the fan 16 are configured to operate in conjunction with the photoelectric sensor 11 , but the present invention is not limited to this, and the photoelectric sensor 11 may be provided. Just before use, the water film water supply valve b1 and the fan 16 are turned on, and the toilet flushing water supply valve b2 is turned on after using the toilet. Also good.
＜発明の効果＞
本発明は上記の構成であるから、以下の利点を
有する。<Effects of the Invention> Since the present invention has the above configuration, it has the following advantages.
用便中水膜用給水弁の開弁に伴つて瞬間流量
の少ない洗浄水がリム通水路へ給水されること
により、ジエツト連絡孔の周縁部を越えられず
洗浄水のほとんど全部が射水孔から吐水される
ので、用便時にリム通水路から射水孔だけに洗
浄水を供給してボウル内面全体にウオーターカ
ーテンを形成することができる。 Due to the opening of the water supply valve for water film during urination, the small instantaneous flow rate of flushing water is supplied to the rim passageway, so that almost all of the flushing water cannot pass through the periphery of the jet communication hole, and almost all of the flushing water flows from the water injection hole. Since water is spouted, it is possible to form a water curtain on the entire inner surface of the bowl by supplying washing water only to the water injection hole from the rim water passage when using the toilet.
従つて、用便中にリム通水路へ給水すると洗
浄水が射水孔に供給されるだけでなくジエツト
連絡孔を介して導水路にも供給され、ジエツト
孔から洗浄と関係なく無駄に排出される従来の
ものに比べ、洗浄水がジエツト孔から無駄に排
出されず節水できて経済的である。 Therefore, when water is supplied to the rim water passage during urination, the flushing water is not only supplied to the water injection hole but also supplied to the water conduit through the jet communication hole, and is wasted from the jet hole without any connection to cleaning. Compared to the conventional type, cleaning water is not wasted and is not discharged from the jet hole, so water can be saved and it is economical.
用便中ボウル部内面の封水部以外の乾燥面に
直接小便が放出されると小便が飛散し易いが、
本発明は用便中ボウル内面全体にウオーターカ
ーテンが形成されるので、小便器の飛散が起こ
り難い。 If urine is released directly onto a dry surface other than the water-sealed part on the inner surface of the bowl while defecating, it is likely to scatter.
In the present invention, since a water curtain is formed on the entire inner surface of the urinal bowl, it is difficult for the urinal to scatter.
