本発明の洗濯装置における基本構成について、図面を参照して説明する。図1は、本発明の洗濯装置を構成するケーシング周辺における各流路の関係を示す概略図である。又、図2は、本発明の洗濯装置のケーシング内に設けられる洗濯槽の構成を示す概略斜視図である。更に、図3は、図2に示す洗濯槽の回転軸に垂直な方向における洗濯槽の概略断面図であり、図4は、図3における要部拡大図である。
図1に示すように、本発明の洗濯装置は、その基本構成として、洗浄液を内部に充填密封するケーシング1と、このケーシング1内部に設けられる円筒形状の洗濯槽2と、ケーシング1に洗浄液を供給する給液流路3と、ケーシング1から洗浄液を排出する排液流路4と、ケーシング1内の空気の排気と吸気とを行う空気流路5とを、その主要部として備える。そして、洗濯槽2は、その中心軸が鉛直方向から水平方向に傾斜され、この中心軸を中心としてケーシング1内で回転する。尚、ケーシング1は、洗濯槽2と同心円状の断面を備える円筒形状に限られるものではなく、その内部で洗濯槽2が自由に回転できる形状であればよい。
上述のように、洗浄液が充填密封されたケーシング1内を、その内部に被洗浄物を収容した洗濯槽2が回転することで、洗濯槽2内の洗浄液に圧力分布を形成し、洗濯槽2内の洗浄液の流れによって被洗浄物を損傷することなく洗浄できる。この洗浄液の流れを利用した洗浄を説明するにあたって、まず、ケーシング1内に充填密封された洗浄液に対して流れを形成する洗濯槽2の構造について、図2~図4を参照して説明する。
本発明の洗濯装置における第1の実施の形態について、図面を参照して以下に説明する。図5は、本実施形態の洗濯装置における配管の概略構成を示すブロック図である。本実施形態の洗濯装置は、上述の基本構成で説明した構成を有するケーシング1及び洗濯槽2を備えるとともに、ケーシング1内に洗浄液を充填密封させるための図5に示す各流路が構成される。
まず、洗濯装置は、図5に示すように、給液流路3(図1参照)として、洗浄液を一時的に貯水するタンク31と、タンク31に貯水された洗浄液を吸い上げるポンプ32と、タンク31とポンプ32との間を接続するポンプ吸入側配管33と、ポンプ32とケーシング1との間を接続するポンプ吐出側配管34と、ポンプ吸入側配管33に設けられた制御弁35とを備える。又、タンク31には、タンク31内に洗浄液を供給するとともに制御弁37を有するタンク供給用配管36と、タンク31内の洗浄液の量を検出する液量検出センサ38とが設置される。尚、液量検出センサ38は、例えば、タンク31内の洗浄液の液面に浮遊するフロートを備えた液位センサなどで構成した場合、フロートと接続された継手の角度や高さ位置を、洗浄液の量を示す電気信号に変換して出力できる。
1.洗浄液の供給
次に、図5に示す構成の配管を備えた洗濯装置による洗浄における各工程に対する制御フローについて、以下に説明する。制御部100は、制御弁35及びポンプ32に制御信号を与えて、制御弁35を閉じた状態とするとともに、ポンプ32を停止状態とする。そして、制御部100が制御弁37に制御信号を与えることで、制御弁37を開き、タンク供給用配管36を通じて洗浄液をタンク31内に供給させる。尚、ケーシング1への洗浄液の供給が禁止されるとともに、タンク31内に洗浄液が供給される状態であればよいので、制御弁35が閉じた状態であれば、制御弁46,47については開閉いずれの状態であっても構わない。
そして、制御部100は、液量検出センサ38からの電気信号より、ケーシング1を洗浄液で充填密封させ、且つ、洗浄液を循環可能な量となる洗浄液が、タンク31内に貯えられたことを確認すると、制御弁37に制御信号を与えて制御弁37を閉じる。これにより、タンク供給用配管36による、タンク31への洗浄液の供給を停止する。そして、制御部100は、制御弁35,46,47に制御信号を与えて、制御弁35,47を開く一方で、制御弁46を閉じる。即ち、ケーシング1を含む洗浄液の循環路を開放するとともに、タンク31からポンプ32への洗浄液の供給路を開放する。このように洗浄液の流路を形成すると、ポンプ32を駆動して、タンク31内の洗浄液を吸い上げて、ケーシング1への供給を開始する。尚、ポンプ32の負担を低減するために、制御弁47を最初は閉じた状態とし、ポンプ32を駆動して洗浄液の吸い上げを開始した後に制御弁47を開くものとしてもよい。
制御部100が、空気弁51からの電気信号によって、ケーシング1の洗浄液による充填密封を検出すると、制御弁35に制御信号を与え、制御弁35を閉じる。即ち、制御弁47のみが開いた状態となり、ポンプ32の駆動により、ケーシング1に対する洗浄液の循環が開始される。このケーシング1に対する洗浄液の循環を開始すると、洗濯槽2に収容した被洗浄物の洗浄を行うために、制御部100が、洗濯槽2を回転させるように、駆動機構26(図2参照)に対して、回転駆動の開始する指令を与える。これにより、ケーシング1に対する洗浄液の循環と洗濯槽2の回転による、被洗浄物に対する洗浄工程が開始する。
そして、制御部100は、洗濯槽2の回転を開始してから所定時間の経過を確認するなどして、洗浄液の循環と洗濯槽2の回転による洗浄工程の終了を検知する。尚、洗浄液に混入された不純物を測定するセンサを、ケーシング1を含む循環路に設け、このセンサの測定値によって、被洗浄物の汚れが落ちたことを制御部100が確認したときに、この洗浄工程の終了を検知するものとしてもよい。制御部100は、この洗浄工程の終了の検知によって、洗浄された被洗浄物をケーシング1から取り出すために、ケーシング1に充填密封された洗浄液の排出を開始する。
本発明の洗濯装置における第2の実施の形態について、図面を参照して以下に説明する。図6は、本実施形態の洗濯装置における配管の概略構成を示すブロック図である。尚、図6に示す構成において、図5に示す構成と同一の目的で使用する部分については、同一の符号を付して、その詳細な説明は省略する。
本実施形態の洗濯装置は、第1の実施形態の洗濯装置(図5参照)と異なり、ケーシング1に対して循環させる洗浄液の循環路に、タンク31が含まれる構成とするとともに、排液用配管41とドレイン配管42とが、ケーシング1の別の位置に設けられる。即ち、本実施形態の洗濯装置は、図6に示すように、ケーシング1に対して、ポンプ吐出側配管34、排液用配管41、ドレイン配管42、及び空気流路5が接続される。これにより、ケーシング1には、ポンプ吐出側配管34より洗浄液が供給され、排液用配管41及びドレイン配管42より洗浄液が排出され、空気流路5より空気の吸入と排出がなされる。
このように構成される図6の洗濯装置による洗浄における各工程に対する制御フローについて、以下に説明する。尚、制御部100は、空気弁51及び液量検出センサ38の電気信号が入力されるとともに、制御弁46,62,63,67~69及びポンプ32に対して制御信号を出力する。
制御部100は、制御弁46,63,68に制御信号を与えることで、制御弁46,68を閉じた状態とするとともに、制御弁63を開いた状態とする。又、ポンプ32を停止状態とするとともに、制御弁62,67,69については開閉いずれの状態であっても構わない。これによって、給液配管61を通じて、洗浄液がケーシング1内に供給される。制御弁46を閉じて、ケーシング1の下部に接続されたドレイン配管42からの洗浄液の流出が禁止されるため、ケーシング1内に洗浄液が充填される。
このように洗浄液の循環が開始すると、制御部100が、駆動機構26(図2参照)に対して、回転駆動の開始する指令を与えることで、洗濯槽2の回転が開始されて、洗濯槽2に収容された被洗浄物が洗浄される。即ち、充填密封されたケーシング1内で洗濯槽2が回転することで、洗濯槽2内には流速分布に基づく圧力分布が形成され、上述したような、被洗浄物の洗浄が行われる。このとき、洗濯槽2は、その回転により、洗濯槽2内部の洗浄液と洗濯槽2外部の洗浄液との入れ換えがスリット23(図2参照)で行われ、洗濯槽2内の洗浄液が循環する。
そして、制御部100は、第1の実施形態と同様、洗濯槽2の回転開始からの時間経過或いは洗浄液の汚れ具合などによって、洗浄液の循環と洗濯槽2の回転による洗浄工程の終了を検知する。制御部100は、この洗浄工程の終了の検知によって、洗浄された被洗浄物をケーシング1から取り出すために、ケーシング1に充填密封された洗浄液の排出を開始する。即ち、第1の実施形態と同様、ケーシング1に充填密封された洗浄液の排出を開始するために、制御部100によって、ポンプ32の駆動が停止されるとともに、制御弁46が開かれる。このとき、タンク31からも洗浄液を外部に排出するために、制御部100は制御弁67にも制御信号を与えて、制御弁67を開く。
本発明の洗濯装置における第3の実施の形態について、図面を参照して以下に説明する。図7は、本実施形態の洗濯装置における配管の概略構成を示すブロック図である。尚、図7に示す構成において、図6に示す構成と同一の目的で使用する部分については、同一の符号を付して、その詳細な説明は省略する。
本実施形態の洗濯装置は、第2の実施形態の洗濯装置(図6参照)と異なり、空気流路5として、ケーシング1とタンク31とを接続した吸排気用配管52を備え、空気弁51が除かれた構成となる。尚、タンク31は、大気開放された構成とし、吸排気用配管52は、第1及び第2の実施形態における空気流路5と同様、鉛直方向に対してケーシング1の上部に設置される。これにより、ケーシング1は、この吸排気用配管52とタンク31とを通じて大気開放された構成となる。又、詳細は後述するが、ケーシング1が洗浄液で充填密封された後は、この吸排気用配管52に洗浄液が流れてタンク31まで送出するため、吸排気用配管52は、排液用配管41と同様の機能を果たす。
1.ケーシングの充填密封
このように構成される図7の洗濯装置による洗浄における各工程に対する制御フローについて、以下に説明する。制御部100は、制御弁46,63,67~69に制御信号を与えることで、制御弁46,67~69を閉じた状態とするとともに、制御弁63を開いた状態とする。又、ポンプ32を停止状態とするとともに、制御弁62については開閉いずれの状態であっても構わない。これによって、第2の実施形態と同様、給液配管61を通じて、洗浄液がケーシング1内に供給される。制御弁46を閉じて、ケーシング1の下部に接続されたドレイン配管42からの洗浄液の流出が禁止されるため、ケーシング1内に洗浄液が充填される。
このように洗浄液の循環が開始すると、第2の実施形態と同様、洗濯槽2の回転が開始されて、洗濯槽2に収容された被洗浄物が洗浄される。回転する洗濯槽2を内部に備えたケーシング1は、ポンプ32によってタンク31より汲み上げられた洗浄液が、ポンプ吐出側配管34から供給されると同時に、排液用配管41及び吸排気用配管52から洗浄を行った洗浄液が排出される。排液用配管41及び吸排気用配管52によりケーシング1から排出された洗浄液はタンク31に送出される。そして、タンク31内の洗浄液は、排液用配管64を通じて廃液処理部66に与えられて、洗浄液の再生処理が行われた後、ポンプ吸入側配管33を通じてポンプ32に送出される。
その後、制御部100が、洗浄液の循環と洗濯槽2の回転による洗浄工程の終了を検知すると、第2の実施形態と同様、ポンプ32の駆動を停止するとともに、制御弁46,67を開いて、ケーシング1に充填密封された洗浄液の排出を開始する。これにより、本実施形態の洗濯装置においても、第2の実施形態の洗濯装置と同様、ケーシング1内の洗浄液だけでなく、タンク31内の洗浄液についても、廃液処理部44に排出される。
