 また、便器洗浄システム1は、給水路6,8から分岐して設けられ、便器2の排水部5に接続された排水路9に接続されるバイパス給水路10を備えている。なお、以下では、このバイパス給水路10が分岐接続された分岐部10aよりも上流側(給水源側)の給水路6を上流側給水路6とし、分岐部10aよりも下流側(便器2側)の給水路8を下流側給水路8として説明する。
 バイパス給水路10には、バイパス給水路10を開閉し、洗浄水を供給及び遮断するバイパス弁11が設けられている。また、バイパス給水路10には、上流側への逆流を防止する逆流防止弁(逆止弁、チェックバルブ)等の逆流防止部12が設けられている。この逆流防止部12は、バイパス弁11よりも下流側(排水路9側)に設けられている。このバイパス給水路10の下流側端部は、横引配管状とされた排水路9の排水部5に比較的近接した部位に接続されている。このバイパス給水路10の下流側端部を、排水路9の略水平方向に延びるように設けられた部位の上流側端部に接続するようにしてもよい。
The toilet bowl cleaning system 1 further includes a bypass water supply passage 10 branched from the water supply passages 6 and 8 and connected to the drainage passage 9 connected to the drainage portion 5 of the toilet bowl 2. In the following, the water supply passage 6 on the upstream side (water supply source side) of the branch portion 10a where the bypass water supply passage 10 is branched and connected is referred to as the upstream side water supply passage 6, and the downstream side (the toilet 2 side) Will be described as the downstream side water supply passage 8).
The bypass water supply passage 10 is provided with a bypass valve 11 that opens and closes the bypass water supply passage 10 to supply and shut off washing water. Further, the bypass water supply passage 10 is provided with a backflow prevention portion 12 such as a backflow prevention valve (a check valve, a check valve) and the like for preventing a backflow to the upstream side. The backflow prevention unit 12 is provided downstream of the bypass valve 11 (on the side of the drainage passage 9). The downstream end of the bypass water supply passage 10 is connected to a portion relatively close to the drainage portion 5 of the drainage passage 9 formed in a cross-pull piping manner. The downstream end of the bypass water supply passage 10 may be connected to the upstream end of a portion provided to extend in the substantially horizontal direction of the drainage passage 9.
 また、便器洗浄システム1は、このバイパス給水路10に供給される洗浄水に空気を気泡化させて混入させる気泡混入部13を備えている。本実施形態では、気泡混入部13を、バイパス給水路10が分岐接続された分岐部10aよりも上流側の上流側給水路6において気泡を混入させるように設けた構成としている。この気泡混入部13としては、ミリメートルオーダー及びマイクロメートルオーダーの両方または一方の微細気泡を混入させる構成とされたものでもよい。また、この気泡混入部13は、微細気泡が混入された泡洗浄水(微細気泡含有洗浄水)のボイド率(流体の単位断面積当たりに含まれる気泡の面積割合)が5%~40%程度、好ましくは、10%~30%程度となるように設定されたものでもよい。 In addition, the toilet bowl cleaning system 1 is provided with a bubble mixing portion 13 which causes air to be bubbled and mixed in the cleaning water supplied to the bypass water supply passage 10. In the present embodiment, the air bubble mixing portion 13 is configured to mix air bubbles in the upstream water supply passage 6 on the upstream side of the branching portion 10a to which the bypass water supply passage 10 is branched and connected. The bubble mixing portion 13 may be configured to mix fine bubbles of one or both of millimeter order and micrometer order. Further, the bubble mixing portion 13 has a void ratio (the area ratio of the bubbles contained per unit cross sectional area of the fluid) of about 5% to 40% of the bubble wash water (fine bubble containing wash water) mixed with the fine bubbles. Preferably, it may be set to be about 10% to 30%.
 本実施形態では、気泡混入部13は、上流側給水路6に圧力急変部として設けられたベンチュリー管状の気液混合部16と、この気液混合部16に空気を導入する空気導入部14と、を備えている。空気導入部14としては、管路の先端が大気開放されたものでもよく、管路途中に開閉弁が設けられたものでもよい。また、空気導入部14としては、空気に炭酸ガスやオゾンガスなどの機能ガスを含む気体を導入させるものでもよい。また、本実施形態では、空気導入部14の下流側に、気液混合部16に向けて供給される空気の流量調整が可能とされた流量調整部15を設けた構成としている。この流量調整部15を調整することで、上記したボイド率の調整がなされるものでもよい。 In the present embodiment, the air bubble entraining unit 13 includes a venturi tubular gas-liquid mixing unit 16 provided in the upstream water supply passage 6 as a pressure sudden change unit, and an air introducing unit 14 for introducing air into the gas-liquid mixing unit 16. And. As the air introduction part 14, the tip of the pipe line may be open to the atmosphere, or an on-off valve may be provided in the middle of the pipe line. Further, as the air introducing unit 14, a gas containing a functional gas such as carbon dioxide gas or ozone gas may be introduced into the air. Further, in the present embodiment, on the downstream side of the air introducing unit 14, a flow rate adjusting unit 15 capable of adjusting the flow rate of the air supplied toward the gas-liquid mixing unit 16 is provided. The void ratio may be adjusted by adjusting the flow rate adjusting unit 15.
 気液混合部16には、ノズル状に形成された絞り部が設けられ、この絞り部を経て吐出される洗浄水の負圧作用によるエゼクター効果によって空気導入部14から空気が導入される。また、このように導入された空気は、気液混合部16の細径部及び拡径部を通過する際における圧力急変作用によってせん断されて細分化され、微細気泡となって洗浄水に混入される。このような構成とすれば、上流側給水路6に洗浄水を流せば、その負圧作用によって空気が取り込まれて泡洗浄水を生成することができるので、薬剤の補充等が不要となり、また、薬剤排出による環境への影響を生じ難くすることができる。 The gas-liquid mixing unit 16 is provided with a throttling portion formed in a nozzle shape, and air is introduced from the air introducing portion 14 by the ejector effect by the negative pressure action of the cleaning water discharged through the throttling portion. In addition, the air introduced in this way is sheared and subdivided by the pressure sudden change action when passing through the small diameter portion and the large diameter portion of the gas-liquid mixing unit 16, and it is mixed into the cleaning water as fine bubbles. Ru. With such a configuration, if washing water is allowed to flow into the upstream water supply channel 6, air can be taken in by the negative pressure action to generate bubble washing water, so that replenishment of medicines becomes unnecessary, and It is possible to make it difficult to cause environmental impact due to drug discharge.
