(概要)
まず、本実施形態に係る電解液体生成システム1の概要について、図1を参照して説明する。図1は、第1実施形態に係る電解液体生成システム1を示すブロック図である。
次に、本実施形態に係る電解液体生成システム1の詳細について、図1及び図2を参照して説明する。図2は、電解液体生成システム1が備える電解部42を示す分解斜視図である。
本実施形態に係る電解液体生成システム1は、図1に示すように、液体供給部2、液体流入路31、液体流出路32、機能部4、制御部5、給水口6、電源7、及び検出部8を備える電解液体生成装置である。電解液体生成装置は、液体供給部2、液体流入路31、液体流出路32、機能部4、制御部5、給水口6、電源7、及び検出部8を1つの筐体に設けた構成を有する。
液体供給部2は、給水ポンプを備えており、上水道P1から供給された水道水W1を加圧し、加圧した水道水W1を液体流入路31に吐出する。液体供給部2は、水道水W1を溜めるタンクを更に備えていてもよい。
液体流入路31は、本開示の液体流路に相当し、ホース、樹脂管、又は金属管などの水管である。液体流入路31の流入口は液体供給部2に接続しており、液体供給部2から液体流入路31に水道水W1を受ける。液体流入路31の流出口は機能部4に接続しており、液体流入路31を流れる水道水W1を、機能部4に供給する。
機能部4は、流量調整部41、及び電解部42を備える。そして、流量調整部41及び電解部42を備える機能部4は、液体流入路31から供給された水道水W1を電気分解することで、水道水W1からオゾン水W2を生成する電解液体生成機能を実施しつつ水道水W1を除菌する除菌機能を実施する。なお、除菌機能は、水道水W1に電解処理を施して、水道水W1に含まれる菌を減少させる(除菌する)ことで、菌が少ないオゾン水W2を生成する機能である。
流量調整部41は、液体流入路31の流出口と電解部42との間に接続されている。そして、流量調整部41は、電磁弁などを備えており、電磁弁の開度を調整することで、液体流入路31から電解部42に供給される水道水W1の流量を調整する。なお、以降では、液体流入路31から電解部42に供給される水道水W1の流量を、液体供給量と呼ぶことがある。
電解部42は、流量調整部41によって流量調整された水道水W1を電気分解することで、オゾンを発生させ、当該オゾンを水道水W1に溶解させることで、電解液体であるオゾン水W2を生成する。
液体流出路32は、ホース、樹脂管、又は金属管などの水管である。液体流出路32の流入口は電解部42の下流側接続部424(図2参照)に接続しており、電解部42から液体流出路32にオゾン水W2が流れ込む。液体流出路32は給水口6に接続しており、液体流出路32を流れるオゾン水W2は、給水口6から電解液体生成システム1の外部に供給される。
給水口6は、液体流出路32を流れるオゾン水W2を、電解液体生成システム1の外部に供給する。
電源7は、電解部42に駆動電圧を印加して、陽極42cと陰極42dとの間に電位差を生じさせ、陽極42cから陰極42dに向かう駆動電流を発生させる。すなわち、電源7は、電解部42に駆動電圧を印加し、電解部42に駆動電流を供給する。
検出部8は、水道水W1及びオゾン水W2の少なくとも一方の汚れの程度を検出する。汚れの程度が低い程、清潔、無害であるとみなされる。
制御部5は、コンピュータシステムを備える。すなわち、制御部5では、CPU(Central Processing Unit)、又はMPU(Micro Processing Unit)などのプロセッサがメモリに記憶されているプログラムを読み出して実行することによって、制御部5の一部又は全部の機能が実現される。制御部5は、プログラムに従って動作するプロセッサを主なハードウェア構成として備える。プロセッサは、プログラムを実行することによって機能を実現することができれば、その種類は問わない。プロセッサは、半導体集積回路(IC)、又はLSI(large scale integration)を含む一つ又は複数の電子回路で構成される。ここでは、ICやLSIと呼んでいるが、集積の度合いによって呼び方が変わり、システムLSI、VLSI(very large scale integration)、若しくはULSI(ultra large scale integration)と呼ばれるものであってもよい。LSIの製造後にプログラムされる、フィールド・プログラマブル・ゲート・アレイ(FPGA)、又はLSI内部の接合関係の再構成又はLSI内部の回路区画のセットアップができる再構成可能な論理デバイスも同じ目的で使うことができる。複数の電子回路は、一つのチップに集積されてもよいし、複数のチップに設けられてもよい。複数のチップは集約して配置されてもよいし、分散して配置されてもよい。
制御部5は、複数の制御モードのいずれかで動作する。複数の制御モードは、第1制御モード及び第2制御モードを含む。制御部5は、第1制御モードでは、第2制御モードに比べて電解液体生成機能を向上させる。制御部5は、第2制御モードでは、第1制御モードに比べて除菌機能を向上させる。すなわち、制御部5は、第1制御モードでは電解液体生成機能を優先させ、第2制御モードでは除菌機能を優先させる。この結果、電解液体生成システム1は、水道水W1の除菌と、オゾン水W2の生成効率と、のバランスを調整することができる。
第1動作例では、電解液体生成システム1は、以下のように動作する。
第2動作例では、電解液体生成システム1は、以下のように動作する。
第3動作例では、電解液体生成システム1は、以下のように動作する。
