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。
