與水槽31之間延伸之第2管路52。«式洗衣機丨之循環栗 71固定於底座712。第2管路52之_端部係連接於循觀Μ 312 ，第2管路52之他端部連接於水槽31之流入口 水槽31、第1官路51、排水控制單元7及第2管路52形 成洗蘇液之循環路，環泵71錢知驗在循環路内由排 出口 311朝向流入口 312流動、循環。 7控制早707除了播環泵71之外，還具有：作為惑 洗滌液濁度之濁度感測器使用之光感測器72、作為感測 蘇液導電度之導電_器使狀電_測||73、用以將 蘇液排到外部之排水管路74、及配設於排水管路74之十 8 201111581 部之排水閥75。排水閥75用以開關排水管路74。排水控制 單元7更包含用以收集由苐1管路51流入之洗滌液所含之棉 纖維（棉屬等）之過〉慮部7 6。 排水閥7 5係在例如清洗步驟結束時或沖洗步驟結束時 開啟。其結果是，洗滌液會自第1管路51流入到排水控制單 元7。然後，洗滌液通過過濾部76而施行棉纖維之除去處理 後排出到外部。 當排水闊7 5關閉並且循環栗71作動時，水槽31内之洗 務液會通過第1管路51而流入到排水控制單元7。然後，洗 滌液通過配設於排水控制單元7内之過濾部76，除去辦汙成 分。通過過濾部76之洗滌液會通過連接於循環泵71之吸引 口之吸引管路711而流入到循環泵71内。然後，洗滌液會通 過連接到循環泵71之吐出口之第2管路52而回到水槽31 内。在執行清洗步驟或沖洗步驟期間，亦可視需要而反覆 進行上述之洗滌液的循環。洗滌液之反覆循環會提供於品 質尚之清洗步驟或沖洗步驟。 循環泵71之旋轉數亦可改變。當循環泵71之旋轉數設 定較高時（例如，3500rpm)，流入到水槽31之流入口 312之 洗滌液會順著朝向旋轉滚筒3 2内之軌跡而移動（參照第1圖 中箭頭Fi)。另一方面，循環泵71之旋轉數設定較低時（例 如’ lOOOrpm)’流入到水槽31之流入口 312之洗滌液會朝向 在旋轉滾筒32與水槽31之間形成的空間内（參照第1圖中箭 頭 Fo)。 循環泵71在例如清洗步驟與沖洗步驟中之至少1個步 201111581 驟開始時’進行低速旋轉。其結果是，可抑制洗滌結束時 溶解殘留之洗劑或柔軟劑投入後之高濃度柔軟劑落下到旋 轉滚筒32内之洗滌物。 流入到轉滾筒3 2與水槽31之間之空間的洗滌液會自 排出口 311朝排水系統5排出，並且再次回到水槽31之流入 口312(水槽内循環步驟八藉由反覆進行水槽内循環步驟， 促進洗劑之溶解，及/或柔軟劑之濃度之均一化。而且， 可適當避免溶解殘留之洗劑或高濃度之柔軟劑造成洗滌物 之印潰等問題。 水槽内循環步驟宜在例如清洗少驟及/或沖洗步驟中 之供水步驟約10秒後設定。取而代之，水槽内循環步驟亦 可在例如感測由水槽31之下端起算約40mm之液位時才開 始。其結果是，可適當避免洗滌液未充分充滿於循環泵71 内之期間之循環系71的作動。而且，可避免循環系71之空 洞現象(cavitation)造成之怪音、不足之洗蘇液量造成之循環 泵71之異常溫度以及在異常溫度下之循環泵71的作動。 滾筒式洗衣機1進而亦可具有用以將洗澡水供给往水 槽31之泵。泵亦可在將洗澡水供給到水槽31後，執行水槽 /盾衣步驟。而且，洗澡水供給用之泵與循環泵71不同時 動作，可抑制令使用者感到不愉快之大嗓音。 、 亦可透過插作面板g之操作而對滚筒式洗衣機丄設定 亦運轉。滚筒式洗衣機！進行預約運轉時，水槽内循環 ^可在例如—般時間之2倍長的期間進行。其結果是， 虽地溶解在預約待機中（進行預約設定後到滚筒式洗衣機i 10 201111581 實際開始動作之期間）固化之洗劑。而且，預約運轉期間， 可得到充分的洗淨力並且可減少未溶解之洗劑量。 滾筒式洗衣機1亦可視需要而具有溫度感測器。因應於 使用溫度感測器所測定之洗滌液之溫度，改變水槽内循環 步驟之長度。例如，當溫度感測器感測到5°C之洗滌液之溫 度時，則執行例如感測到20°C之洗滌液之溫度時之倍數之 長度的水槽内循環步驟。其結果是，即使在低水溫下也可 充分溶解洗劑。 第2圖係第1圖所示之排水控制單元7之筐體的截面 圖。第2(a)圖係顯示筐體之其中一截面。第2(b)圖係顯示筐 體之相反側之截面。 排水控制單元7包含筐體70。筐體70安裝有第1圖所示 之循環泵71、光感測器72、電極感測器73、排水管路74、 排水閥75及過濾部76。筐體70包含朝水平方向延伸之直管

如第12圖所示，一對電極部73如、73%係沿著直管部 01之長向方向並瓶置。由—對電極部739a、739b之轴所 定義之平面!>係對直f部則之轴大略平行。上游之電極部 18 201111581 739a係將沿著直管部701之軸流動之洗滌液分流為上下方 向。因此’橫切平面P之洗滌液的流量會變少。其結果是， 適合用於測定洗滌液之導電度之電極部739a、739b之間的 空間（例如’ 15mm以上30mm以下之空間）中，洗滌液之 流動性降低。而且，得到適合導電度之測定之洗滌液的流 動0 又’如第12圖所示，包含一對電極部739a、739b之軸 的平面P係呈水平面。一對電極部739a' 739b並且宜為不橫 切直管部701之内部空間上部（排水控制單元7在設計上可 能發生存留空氣之空間（例如，直管部7〇1之内部空間中上 側1/5之區域））及直管部7〇1之内部空間下部（排水控制 單元7在設計上可能堆積髒汙成分之空間（例如，直管部701 之内。卩二間中下側丨/5之區域））。其結果是，電極部73如、 739b之犬出部份之面全體接觸於直管部内之洗滌液。因 可抑制對於測定直管部7 〇 1内之空氣之導電度的影響。 又’電極部739a、739b在直管部70i之内部空間中上側4/ 5 之區域突出時，可抑制對於在直管部7〇1内堆積之薪汗成分 之導電度之測定的影響。 第13圖係模式地顯示光感剛器72及電極感測器73周圍 之^將液之流動。第13圖中顯示第戰細中相關說明 之光感測n72之發光元件721_光元件722之間之紅外光 線之光路250。又，與第12圖同樣， 對於配置於上游側之電 極。卩附上標號739a，對於配 、下游側之電極部附上標號 19 201111581 為了防止升>成光路250之紅外光線之不必要的折射，形

測器72之紅外光線不會對洗滌液之流動造成任何影響。因 此，業經整流之洗滌液之液流會到達電極部739a、73外。 如第12圖之相關說明，藉由上游之電極部739&，平行 於直官部701之軸方向之液流的一部份會朝上下分流。其結 果是，洗滌液之液流會被擾亂。電極部739a造成之洗滌液 之液流的擾亂由於係在比第7圖至第9圖相關說明之光感測 器72更靠近下游側發生，因此幾乎不會對光感測器72進行 之濁度測定造成影響。 如第12圖相關說明，由電極部乃如、73%之軸所定義 之平面P係對直管部701之軸大略平行。因此，例如，若在 直管部701内使洗滌液為逆流（由直管部7〇1朝水槽31之排 出口 311 (參照第1圖）之方向），電極部739b會使洗滌液之 液流朝上下分流，但電極部739a在洗滌液之液流方向中， 會與電極部739b重疊’因此不會過度擾亂洗滌液之液流。 因此，即使係使洗滌液逆流之情況，亦可以較高精度感測 通過光路250之洗條液的濁度。 201111581 在劃疋平坦内面772之上側之界線的上緣3 91及劃定平 坦内面772之下側之界線的下緣392中，I管部1係成屈曲 成凹狀之截面輪廓形狀（參照第7圖）。在構成該屈曲之截 面輪廓形狀之部份中，洗滌液之液流比其他部份容易滞 留。如第13圖所示，電極部739a、739b配设成：電極部739a、 739b之截面之一部份會進入平坦内面772。在由電極部 739a、739b所挾持之上緣391附近，由於洗滌液特別容易滯 留’因此可得到適合測定洗滌液導電性之低流動性的液 流。又’藉由在電極部739a、739b之間所劃定出之平面p與 上緣391大略平行，藉此可更為提高導電度之測定精度。 再次參照第1圖至第5圖。電極感測器73之下游配設有 循環栗71。循環泵71與排水控制單元7之筐體7〇之間配設有 吸引管路711 ’吸引管路711包含：與循環泵71之吸引口連 接之一端部、及連接於在排水控制單元7之筐體7〇形成之第 2開口部771之他端部。由循環泵71之吐出口延伸之第2管路 52連接於在水槽31形成之流入口 312。 第14圖係模式地顯示由電極感測器7 3到循環泵7丨之洗 滌液之液流的平面圖。與第圖一併參照第丨圖及第2圖。 第14圖中係顯示吸引管路γη。如第14圖所示，電極感測器 73係配沒於比吸引管路711與排水控制單元7之連接部77 j (第2圖中顯示為第2開口部更靠近上游側。又，與第 12圖同樣，對配置於上游側之電極部附上標號739a，對配 置於下游側之電極部附上標號739b。 構成排水控制單元7之筐體70之直管部7〇1及收容管部 21 201111581 702在平面視圖中係形成筆直的流路（第14圖中，直管部7〇ι

739a、739b之棉纖維會變得比較容易由電極部739a、739b 除去。再者，如第2圖所示，收容於收容管部7〇2之過濾部 76(參照第1圖）之一部份存在於電極感測器73與連接部771 之間。第14圖中，在網狀區域中概略地表示過遽部76。洗 務液通過存在於過濾部76之上游位置之電極感測器73後， 且在到達存在於過濾部76之下游位置之吸引管路711之

構成與流入口 312之開口部互補之外周輪廓之環狀突出部 525。環狀突出部525之内部配設有擠壓壁123。擠壓壁123 係由環狀突出部525之内部空間之大略中心位置朝下方彎 曲成弧狀，且具有朝向旋轉滾筒32之旋轉中心方向之截 面。擠壓壁123之兩端連接於環狀突出部525之内壁面。環 狀突出部525與環狀肋121之間配設有〇環122。〇環122係在 環狀突出部525與環狀肋121之間被壓縮，且作為密封構件 之機能。 導管槽溝520之下半管路523與環狀肋121鄰接，且使用 固定具125 (第π圖中，突座係以固定具125表示）固定於 25 201111581 形成於水槽31之壁部之較厚部124。 導官槽溝520進而包含盍524。蓋524與下半管路523 — 倂由導管522所形成之流路屈曲，而形成朝向流入口 312之 流路。藉由彳盾環泵71之作動，由第2管路52通過導管槽溝 520 ’洗務液流入到流入口 312。再者，循環泵71係以例如 3500rpm之旋轉數旋轉。 水槽31之内部配設有旋轉滾筒32。旋轉滾筒32之上面 與流入口 312之間配設有承擋壁丨26。承擋壁丨26係由與水槽 31之外壁連接之連接壁127所支持。承擋壁126與擠壓壁123 形成狹小流路。該狹小流路係作為使洗滌液喷射到洗滌槽3 内之喷射口 129的機能。 通過承擋壁126與擠壓壁123所形成之喷射口 129之洗 滌液接著通過形成於構成水槽31之外面之一部份之前端壁 128與旋轉滾筒32之前端壁321之間之流路281，並供給到旋 轉滾筒32之⑽。前端壁128與擠壓壁123共同動作而推壓〇 環 122。 喷射口 129與旋轉滾筒32係分開形成。旋轉滾筒32内之 洗務物不接觸到噴射口⑶。因此，噴射口129幾乎不會對 洗條步驟、沖洗步驟或麟步驟造成不良影響。喷射口 129 不s傷害洗膝物、使之破損，也幾乎不會損害洗務物之外 7進而’喷射口 129之下游之流路281係由水槽31之前端 壁128與旋轉滾筒取前端壁32ι所形成，因此不需要用以 爲K之追加構造。第17圖所示之構造中，僅使用〇環122 作為密封構件。 1 26 201111581 水槽31之前端壁128及旋轉滾筒32之前端壁321形成環 狀出口部282。通過流路281之洗滌液通過環狀之出口部 282，並且朝旋轉滾筒32之旋轉中心轴喷射。通過出口部282 喷射之洗滌液可有效率地喷射到旋轉滾筒32之内側旋轉區 域。而且，與收容到旋轉滾筒32内之洗滌物的量無關，洗 滌液可有效率地供給到洗滌物。 水槽31之前端壁128之内面（形成流路281之面）包含 傾斜面283與彎曲面284。使流路281之截面積朝下游漸漸減 少之傾斜面283使通過流路281之洗蘇液之流速漸漸增加。 因此，通過流路281之洗滌液會一邊加速一變朝向彎曲面 284。彎曲面284係使洗滌液之液流方向朝旋轉滚筒32之底 部之方向產生變化。因此，由出口部282喷射之洗滌液會朝 向旋轉滾筒32之底部。其結果是，洗滌液可有效率地供給 到洗蘇物。 喷射口 129之開口涵括洗滌槽3之周方向之預定範圍。 連接壁127及承擋壁126係使喷射口 129朝旋轉中心軸方向 開口。連接壁127及承擋壁126幾乎不會擾亂流入到流入口 312之洗滌液，且導引到流路281。洗滌液朝周方向擴散到 喷射口 129，然後安定的流入流路281。然後，洗滌液進一 步朝周方向擴散並流動到環狀出口部282。因此，洗滌液會 由出口部282全體喷射，與收容到旋轉滾筒32内之洗滌物的 量無關，而可安定的供給到洗滌物。 導管槽溝520之蓋524係使用簡單的安裝構造而形成朝 向流入口 312之流路。適當地制定覆蓋流入口 312之蓋524的 27 201111581 形狀以及尺寸、連接壁127之形狀以及尺寸、及承擋壁126 之形狀以及尺寸，藉此可得到適切的洗滌液往旋轉滾筒32 内流入。藉由適當地制定蓋524、連接壁127及承擋壁126之 設計參數，可適切地決定由喷射口 129喷射之洗滌液之流 寬、流厚及流速。而且，與收容到旋轉滾筒32内之洗滌物 的量無關，洗蘇液可有效率地供給到洗滌物。 第17圖所示之導管槽溝520之蓋524之安裝構造或連接 壁127及承擋壁126之非常簡單的構造對於抑制漏水以及製 造成本之低廉化也有所貢獻。 如上所述，導管槽溝520係在下半管路523與蓋524形成 朝向流入口 312之流路。如第1圖所示，導管槽溝520形成之 流路係沿著水槽31之外面延伸。因此，使用下半管路523與 蓋524，在水槽31與筐體2之間之小空隙形成具有矩形截面 之平坦管路。平坦管路係用以規定適合喷射口 129之形狀、 大小之流寬以及流厚之洗蘇液之液流。通過平坦管路之洗 滌液會被整流而朝向噴射口 129。 旋轉滾筒32之前端壁321上形成複數之突條322。突條 322係朝旋轉滾筒32之前端壁321之周方向在預定長度之範 圍内延伸。複數之突條322之周方向的位置及^/或半徑方向 之位置亦可互為不同《突條322可將噴射口 129之下游之流 路28丨之截面積局部縮小。在出口部282附近利用突條322縮 小流路截面積之情況，與在離開出口部282之處利用突條 322縮小流路截面積之情況中，由出口部282喷出之洗滌液 之移動軌跡不同。因此，由出口部282排出之洗滌液會振散 28 201111581 到旋轉滾筒32内之廣大範圍，達成以較高效率將洗滌液供 給到洗蘇物。 突條322之形狀並不限定於第17圖所示者。例如，突條 322亦可為波型形狀，亦可為葉片型形狀。亦可採用可使由 出口部282排出之洗滌液之移動軌跡變動之任意形狀的突 條322。又，亦可採用可使由出口 282排出之洗滌液之移 動軌跡變動之任意形狀之突條322的配置。 承擋壁126與旋轉滾筒32之間形成空隙266。當循環泵 71以低速運轉時（例如，1 OOOrpm )，洗務液會由喷射口 129 流入到空隙266。流入到空隙266之洗蘇液會在旋轉滾筒32 與水槽31之間的空間傳送朝向水槽31之排出口311。 第18圖係例示控制電路部81之機能構成。 控制電路部81包含：演算部813、判定部814及信號發 送部815。演算部813係根據來自光感測器72及電極感測器 73之信號，而算出例如洗劑之種類、洗劑之濃度及髒汙成 分之量。 判定部814根據演算部813算出之結果，判定是否執行 預定之控制。例如，演算部813算出之髒汙成分之量超過預 定之臨界値時，判定部814會使信號發送部815發送使供水 系統統4及/或排水系統5動作之信號。 信號發送部815收到來自判定部814之指令，然後發送 用以使供水系統統4及/或排水系統5動作之信號。例如， 信號發送部815將信號發送到供水系統統4之電磁閥信號， 令電磁閥為開啟狀態，並且將信號發送到排水系統5之排水 29 201111581 閥75，令排水閥為開啟狀態。 與第18圖一併參照第1圖。在清洗步驟及/或沖洗步驟 之間，設置用以測定洗滌液之狀態之期間。此時，由控制 電路部81發送使循環泵71之動作之信號（停止信號）到循 環泵71。當循環泵71停止時，排水控制單元7内之洗滌液之 流動停止。其結果是，得到適合使用光感測器72及/或電 極感測器73之測定的狀態。然而，在停止信號發送後，也 會藉由循環泵71之慣性運動或洗滌液本身之慣性流動，排 水控制單元7内之洗滌液之流動會在預定期間内繼續。在上 述之實施形態中，由於過濾部76配置於該等感測器72、73 之附近，因此，可在較早期抑制停止信號發送後之不佳之 洗務液的流動。因此，可在比較短的期間内以高精度測定 洗滌液之濁度以及導電度。本實施形態中，在感測器72、 73之下游位置，且在使用於與第2圖所示之吸引管路711之 連接之第2開口部771 (連接部771)之上游側配設過濾部 76。因此，所謂循環泵71之慣性運動或者循環泵71之振動 的影響可藉由過濾部76而適當地緩和。而且，可以較高精 度測定洗滌液之濁度以及導電度。 上述說明中，用以測定導電度之電極感測器73係例示 突出於流路中之感測器，但上述之原理不受限於此，亦可 適用於任一種必須與洗滌液直接接觸以感測洗滌液之物性 之感測器的洗衣機。 上述說明中，光感測器72係用以測定洗滌液之濁度， 但亦可使用作為其它之測定目的。上述之原理亦可適用於 30 201111581 用以感測髒汙成分之堆積之光感測器72'或可使用光 器72適當地測定之其他物性或環境變化。 ⑴ 上述說明中，使洗滌液流動之流動裝置係例示泵，曰 取而代之亦可使用配設在循環路或者流路中之螺槳但 滌液流動。 ' 失 一 σ从「僻战之洗衣機。

根據上述構成，藉由感測器測定洗滌液之導電度，可 感測洗滌液所含之洗劑種類或洗劑濃度。又，如上所述， 由於可由感測器促進棉纖維之除去，因此可減低棉纖維造 成導電度對測定之影響。進而，隨著促進棉纖維之除去， 可利用在洗滌液中大幅突出之電極部達成以高精度測定導 電度。 上述構成中，前述感測器宜配設於曝露在由前述排出 口向前述吸引管路之第1流動方向之洗蘇液流、及與該第1

Upstream and/or "downstream". Fig. 1 is a schematic configuration diagram of a drum type washing machine according to an embodiment. Further, the principle described below is not limited to the drum type washing machine shown in Fig. 1, and may be applied to other washing machines (for example, a pulsating pump type washing machine or a stirring type washing machine). The drum type washing machine 1 has a casing 2. A washing tub 3 is provided inside the casing 2. The washing tub 3 includes a cylindrical water tank 31 that is rotatably supported inside the casing 2, a cylindrical rotating drum 32 that is rotatably supported in the water tank 31, and a motor 33 that rotates the rotary drum 32. The water tank 31 and the rotary drum 32 each have a bottom. The motor 330 is mounted outside the bottom of the water tank 31. The sink 201111581 31 is formed to drain the intake inlet 312. The liquid discharge port 311 and the casing 2 for supplying the washing liquid further receive the second discharge port 3U toward the inlet port 312. The water supply system in the water tank of the water tank is fed into the water supply system 4 in the main water tank 31, the water draining system 5 for circulating the washing water, or the drying system 6 is not necessarily the drying of the washing machine 3 System 6. Furthermore, the system 6 of the dry 31 includes a #loop line 61, and the circulation line 61 has a connection with the water discharge port 313 of the water tank_the air for drying the mountain, and is used for feeding from the bottom of the water tank 31. The internal air supply system "drying and drying system 6 further includes a distribution in the circulation line 61. . The air blower 62 is configured to allow air to flow in the circulation line 61, and may also be included as needed: for collecting the dust and the parts, and for the purpose of dehumidifying the introduced air after dedusting. The heating unit 2 heats the dust-removed air and makes the dried high-temperature air panel. The washing machine 1 has an operation draining plate 8 disposed on the upper surface of the front surface of the casing 2, so that the user can select the operation of the drum type washing machine 1.吿丨 Φ mode or various functions. The operation panel 8 includes a control circuit unit 8 that controls the information of the wheeled user to be displayed on the operation panel 8 with the slot: no. Further, the control circuit unit 81 may be used, for example, as a liquid level sensing II for sensing the liquid level in the water, and as a light sensor 72 for sensing the turbidity sensor of the cleaning liquid. Or used as a sense of washing. The electrode sensor 73 of the conductive sensor of the conductivity receives the sensing signal: when the operation of the drum type washing machine is set through the operation panel 8, the control circuit unit controls the water supply system to tear according to the sensing (4) Electric 201111581 Magnetic valve or drainage system 5 contains a drainage valve 75. The motor 33, m secret 4, drain pure 5, and dry system 6 automatically controlled by the control circuit unit 8i perform at least the washing step, the rinsing step, the dehydrating step, and the drying step in accordance with the mode setting or control program. The water supply system 4 includes: a water supply pipe 4 connected to the water tank material and used to accommodate washing and washing. The water supply system supplies water to the water tank 适 through the water supply line 41 in a timely manner by the switching operation of the solenoid valve (refer to the actual line arrow in the figure). Further, the drum-type washing machine 1 shown in the '151th embodiment uses the water supply of the water supply system 4 to appropriately put the lotion in the lotion accommodating portion 42 disposed across the water supply pipe into the water tank 31 in a timely manner. Spit the exit. Further, the drainage system 5 includes a first conduit 51 having one end connected to the discharge port 311 of the water tank 31, and a drain control unit 7 connected to the other end of the lf passage 51. Drainage (4) Unit 7 is responsible for the washing from the water. The draining system 5 further includes a second conduit 52 extending between the circulation system 71 and the water tank 31 of the drainage control unit 7. The "circulating washing machine" of the "type washing machine" is fixed to the base 712. The end portion of the second conduit 52 is connected to the tunnel 312, and the other end of the second conduit 52 is connected to the inlet tank 31 of the water tank 31, the first official road 51, the drainage control unit 7, and the second tube. The road 52 forms a circulation path of the washing liquid, and the ring pump 71 knows that it flows and circulates from the discharge port 311 toward the inflow port 312 in the circulation path. 7 control early 707 in addition to the broadcast ring pump 71, also has a light sensor 72 used as a turbidity sensor for turbid liquid turbidity, as a conductive _ _ _ _ The test||73, the drain line 74 for discharging the liquid to the outside, and the drain valve 75 of the 10th 201111581 part of the drain line 74. The drain valve 75 is used to open and close the drain line 74. The drain control unit 7 further includes a filter portion 76 for collecting cotton fibers (cotton or the like) contained in the washing liquid flowing from the crucible 1 line 51. The drain valve 7.5 is opened, for example, at the end of the washing step or at the end of the rinsing step. As a result, the washing liquid flows from the first line 51 to the drain control unit 7. Then, the washing liquid is subjected to removal treatment of the cotton fibers through the filter portion 76, and then discharged to the outside. When the drain width 7.5 is closed and the circulating pump 71 is actuated, the washing liquid in the water tank 31 flows into the drain control unit 7 through the first line 51. Then, the washing liquid passes through the filter portion 76 disposed in the drain control unit 7, and the staining component is removed. The washing liquid that has passed through the filter unit 76 flows into the circulation pump 71 through the suction line 711 connected to the suction port of the circulation pump 71. Then, the washing liquid is returned to the water tank 31 through the second line 52 connected to the discharge port of the circulation pump 71. During the execution of the washing step or the rinsing step, the above-mentioned washing liquid circulation may be repeated as needed. The reversal cycle of the wash solution will be provided to the cleaning step or rinse step of the product. The number of rotations of the circulation pump 71 can also be changed. When the number of rotations of the circulation pump 71 is set high (for example, 3500 rpm), the washing liquid flowing into the inlet 312 of the water tank 31 moves along the trajectory toward the inside of the rotating drum 3 2 (refer to arrow Fi in Fig. 1). . On the other hand, when the number of rotations of the circulation pump 71 is set low (for example, '100 rpm), the washing liquid flowing into the inlet 312 of the water tank 31 faces the space formed between the rotary drum 32 and the water tank 31 (refer to the first Arrow Fo in the figure. The circulation pump 71 performs low-speed rotation at the start of at least one of the washing step and the rinsing step, for example, at the start of 201111581. As a result, it is possible to suppress the washing of the high-concentration softening agent which has been dissolved in the spinning drum 32 after the washing agent or the softening agent which has been dissolved at the end of washing. The washing liquid flowing into the space between the rotating drum 3 2 and the water tank 31 is discharged from the discharge port 311 toward the drainage system 5, and is returned to the inflow port 312 of the water tank 31 (the inside of the water tank is circulated in step 8 by repeating the inside of the water tank) The step of promoting the dissolution of the lotion and/or the homogenization of the concentration of the softening agent. Moreover, the problem of dissolving the residual lotion or the high concentration of the softening agent to cause the washing of the washing material can be appropriately avoided. For example, the water supply step in the cleaning and/or rinsing step is set after about 10 seconds. Alternatively, the step in the water tank can be started, for example, when sensing the liquid level of about 40 mm from the lower end of the water tank 31. As a result, It is possible to appropriately prevent the operation of the circulation system 71 during which the washing liquid is not sufficiently filled in the circulation pump 71. Moreover, the circulation pump caused by the cavitation of the circulation system 71 and the insufficient amount of the washing liquid can be avoided. The abnormal temperature of 71 and the operation of the circulation pump 71 at an abnormal temperature. The drum type washing machine 1 may further have a pump for supplying bath water to the water tank 31. The pump may also take a bath After the water tank 31 is supplied to the water tank 31, the water tank/shield step is performed. Further, the pump for supplying the bath water does not operate at the same time as the circulation pump 71, and it is possible to suppress the loud noise which is unpleasant to the user. In the drum type washing machine, the drum type washing machine can perform the scheduled operation, and the circulation in the water tank can be performed for a period of twice as long as the normal time. As a result, it is dissolved in the reservation standby (performed After the reservation is set, the detergent is solidified during the period when the drum type washing machine i 10 201111581 is actually started. Moreover, during the scheduled operation, sufficient detergency can be obtained and the amount of undissolved washing can be reduced. The drum type washing machine 1 can also be used as needed. And having a temperature sensor, the length of the circulation step in the water tank is changed according to the temperature of the washing liquid measured by the temperature sensor. For example, when the temperature sensor senses the temperature of the washing liquid at 5 ° C, Then, an in-tank circulation step of, for example, sensing the length of the temperature of the washing liquid of 20 ° C is performed. As a result, it can be charged even at a low water temperature. Fig. 2 is a cross-sectional view of the casing of the drainage control unit 7 shown in Fig. 1.

The flat inner surface 772 extends from the middle of the straight tube portion 701 toward the downstream storage tube portion 702. The flat inner surface 772 extending along the horizontal plane passing through the central axis of the straight tube portion 701 forms a flat strip-shaped region extending toward the receiving tube portion 702. Use of Light Sensor 72 201111581 The flat inner surface 772 of the light exiting and receiving light prevents unwanted refraction of the infrared light used by the light sensor 72. The straight pipe portion 701 is formed with a pair of through holes 773. The through hole 773 is inserted through the electrode sensor 73. The electrode portion of the electrode sensor 73 protrudes into the straight tube portion 7〇1 and is in contact with the washing liquid in which the straight tube portion 701 is covered. Below the internal space of the housing tube portion 702, a first opening portion 774 connected to the drain line 74 and a second opening portion 771 connected to the suction port of the circulation pump 71 are formed. The first opening 774 and the second opening 771 are provided on the surface facing the through hole 773 of the straight pipe portion 7〇1.

Plane (Fig. 9(d))' Plan view (Fig. 9(e)) and bottom view (Fig. 9(f)). The photo sensor 72 includes a light-emitting element 72 that emits infrared light and a light-receiving element 722 that receives infrared light emitted from the light-emitting element 721. The light-emitting element 721 and the light-receiving element 722 disposed on the outer side of the straight tube portion 701 are opposed to each other to form an optical path of infrared light between the light-emitting element 721 and the light-receiving element 722. The straight tube portion 701 is formed of a material that transmits infrared light. The infrared light from the light-emitting element 721 passes through the washing liquid filled in the space surrounded by the wall portion of the straight pipe portion 1. When the turbidity of the washing liquid is large, the amount of infrared light reaching the light receiving element 722 becomes small. On the other hand, when the turbidity of the washing liquid is small, the amount of infrared light reaching the light receiving element 722 becomes large. Moreover, the photo sensor 72 functions as a turbidity sensor for sensing the turbidity of the sachet. The photo sensor 72 further has a support 723 for holding the light-emitting element η and the light-receiving element 722. The support having a slightly U-shaped cross section includes: an i-th support portion 724 for supporting the light-emitting element 721, a second support portion 725 for supporting the optical element 722, and a second! The support unit 72 implants the second bridge 725 connected bridge portion 726. The bridge portion 726 is held at a position where the light-emitting elements 13 201111581 and 7L 722 are opposed to each other. The bridge portion 726 on the straight pipe portion 7〇1 extends at a right angle to the axis of the straight pipe portion 701. In addition to the light-emitting element 721, the first support portion 724 is provided with a circuit board 727 for emitting infrared light from the light-emitting element 721. In the second support portion 725, in addition to the light receiving element 722, a circuit board 728 for generating a voltage signal in response to the amount of infrared light received by the light receiving element 722 is disposed. Further, the photo sensor 72 includes power for supplying power thereto. Circuit board, 729 wire 729. In the thin-plate-shaped circuit boards 727 and 728 (see FIGS. 7 and 8), the longitudinal direction axis extends in the vertical direction. The first support portion 724 has an inner side surface 241 facing the second support portion 725. The inner side surface 241 includes a lens portion 211 of the light emitting element 721. The infrared ray emitted from the illuminating element 721 passes through the lens portion 2A and faces the second supporting portion 725. The lens portion 211 is slightly raised relative to other portions of the inner side surface 241. The second rib (4) is formed along the edge extending inward and downward toward the inner side surface 241. The first rib 242 protrudes from the inner side surface 241 to the inner side (the central axis direction of the straight tube portion 7〇). Second support. The crucible 725 has an inner side surface 251 facing the first support portion 724. The inner side surface 251 includes a lens portion 221 of the light receiving element 722. The infrared ray emitted from the illuminating element 721 passes through the lens portion 221 and reaches the light receiving element 722. The lens portion 221 is slightly raised relative to other portions of the inner side surface 251. The second rib 252 is formed along the edge extending in the upper direction of the side surface 251. The second rib 252 protrudes from the inner side surface 251 to the inner side (the central axis of the straight tube portion). The outer surface of the wall portion of the straight tube portion 701 forming the flat inner surface 772 is also formed into a flat shape. Therefore, the infrared dance emitted by the light-emitting element 72 is not unnecessarily refracted by the two walls of the official portion 701. The support body η] is externally fitted from the upper side toward the straight tube portion 701. The force generating element 721 emits infrared light from the outside of the straight tube portion 7〇1. The light receiving element 722 receives infrared light outside the straight tube portion 701. When the support body 723 is fitted to the straight tube portion 701, the i-th rib 242 of the second support portion 724 and the second rib 252 of the second support portion 725 abut against the flat outer surface of the straight tube portion 7〇1. The first rib 242 and the second rib 252 are separated from the inner side surfaces 241 and 251 of the first support portion 724 and the second support portion 725 by the flat portion 701. As a result, damage of the lens portions 211 and 221 and the straight tube portion 7〇1 caused by the fitting of the support body 723 and the straight tube portion 701 is suppressed. Therefore, the pressure (fitting force) between the ribs 242, 252 and the outer surface of the straight pipe portion 701 can be set high. Moreover, the support body 723 can be firmly mounted to the straight tube portion 701. The central portion of the bridge portion 726 of the support body 723 is formed with an annular receiving wall 26 extending in the vertical direction. The annular receiving wall 261 is formed with a receiving plate 262 forming an upper surface of the bridging portion 726 and a cylindrical receiving space 263. The carrier plate 262 is formed with a through hole 264. The through hole 264 is in communication with the accommodating space 263. The straight pipe portion 701 has a cylindrical protruding portion 265 that extends upward. When the fitting of the support body 723 and the straight tube portion 701 is completed, the protruding portion 265 is inserted into the accommodating space 263, and the upper surface of the protruding portion 265 abuts against the underside of the receiving plate 262. The protruding portion 265 is formed with a screw hole extending downward. The screw inserted into the through hole 264 of the receiving plate 262 is screwed with the screw hole of the protruding portion 265. Further, the support body 723 is firmly fixed to the straight tube portion 701. The receiving plate 262 that straddles the light-emitting element 721 and the light-receiving element 722 can receive falling objects such as dust or water droplets toward the portion of the straight tube portion 7〇1 on which the support 723 is attached. 15 201111581 Refer again to Figures 2 through 6. The drain valve 75 disposed on the slightly downstream side of the photosensor 72 can be coupled to the casing 70 of the drain control unit 7 via the drain line 74. When the drain valve 75 is opened, the straight pipe portion 701 and the washing liquid that is applied to the threshing pipe portion 702 are drained to the outside through the drain pipe 74. The connection position of the drain pipe 74 and the casing 70 can be made near the base end of the housing pipe portion 7〇2. As a result, by opening the drain valve 75, the flow of the washing liquid which is reversed when the circulating pump 71 is actuated is generated around the connection portion between the housing tube portion 7〇2 and the housing tube portion 702 and the straight tube portion 7〇1. . The electrode sensor 73 is disposed closer to the downstream side than the connection position between the drain line 74 and the housing tube portion 7〇2. The electrode M||73 is disposed closer to the downstream side than the photo sensor 72. The photo sensor 72 can function as a turbidity sensor for sensing the turbidity of the wash. The electrode sensor 73 functions as a conductive sensor for sensing the conductivity of the washing liquid. The electrode sensor 73 has a pair of terminal plate W terminal plates which are disposed on the downstream side of the terminal plate 731. The two terminal plates 731, the respective connection wires 733, and the terminal plates 731, 732 are supplied with a high-frequency AC voltage. The frequency of the applied voltage and the vibration H are recommended for washing, and are not particularly limited. The schematic diagram of the terminal block 731 is shown in the figure. Item 1 (a) Diagram of the terminal side view. Fig. 10(b) is a front view of the terminal block 731. And Figure 1 - and ^ Figure 3 and Figure 6. Furthermore, regarding the downstream of the second to sixth embodiments, the 732% of the slabs of the slabs are small and the slabs are 73l_i. The terminal plate 731 constitutes a flexure structure 16 201111581. The edge portions 735 and 736 of the terminal block 731 are deflected in the same direction with the deflection curve 734 extending in the up and down direction as a boundary. Therefore, the terminal plate 731 has high rigidity with respect to the bending moment about the axis of the transverse bending curve 734. A connection portion 737 connected to the electric wire 733 is formed at an upper portion of the terminal block 731. A thick portion 738 having a disk shape and a cylindrical electrode portion 739 are formed on the surface of the terminal block 731 opposite to the deflection direction of the edge portions 735, 736. The terminal plate 731 is connected to the base end portion of the electrode portion 739 via the thick portion 738. The ankle ring 371 is fitted to the base end portion of the electrode portion 739. The electrode portion 739 is inserted into a through hole 773 formed in the straight tube portion 701 of the casing 70 of the drain control unit 7 (see Fig. 2). The terminal block 731 forms a pair of through holes 310. One of the through holes 31 is located above the electrode portion 739. The other through hole 31 is located below the electrode portion 739. The pair of through holes 31A and the electrode portions 739 are aligned in the up and down direction. The deflection curve 734 is parallel to a line connecting the center points of the pair of through holes 31A. The through hole 310 is inserted into a fixture called a bolt. Further, the through hole 31 is a function of the terminal plate 7 31 attached to the fixing portion on the outer surface of the straight tube portion 7 . With the fixing tool, the ring 371 attached to the base end portion of the electrode portion 739 is compressed by the terminal plate 731 being pressed to the outer surface of the straight tube portion 701. The recovery force of the ring 371 and the fixture inserted into the through hole 310 cause the terminal plate 731 to generate a bending moment. The left and right edges of the terminal block 731 are bent along a deflection curve extending in the direction in which the pair of through holes 31 are aligned, whereby the terminal plate 731 has high rigidity against the bending moment. Therefore, the terminal block 731 is firmly attached to the outer surface of the straight pipe portion 701. As a result, the ring 371 17 201111581 disposed at the base end portion of the electrode portion 739 is strongly compressed and exhibits high sealing performance. Further, the through hole 773 formed in the straight pipe portion 701 can appropriately suppress the leakage of the washing liquid. Further, in the present embodiment, the deflection curve 734 is orthogonal to the axis of the bending moment, but the angle of intersection between the deflection curve 734 and the axis of the bending moment is not particularly limited. Further, in the present embodiment, the through hole 31G is disclosed as the fixing portion. Alternatively, it may be replaced by another method, for example, a fixing method of crimping the terminal plate 731 to the outer wall of the straight portion 701 using a jig or The ring ring is made to exert a sufficient force of the sealing function to press the terminal plate 731 against the outer wall of the straight pipe portion 7〇1. Further, when the medicinal device is used, the portion of the terminal plate 731 held by the jig is used as a fixing portion. Fig. U is a cross-sectional view of the straight tube portion 7〇1 to which the terminal plates 731 and 732 are attached. The 11th U) is a cross-sectional view of the terminal plate 731 and the electrode portion 739 located on the upstream side. The U(1) diagram is a cross-sectional view of the terminal plate 732 and the electrode portion 739 located on the downstream side. The electrode portion 739 which protrudes in the straight tube portion 7〇1 across the flat inner surface 772 of the straight tube portion 701 is in contact with the sacrificial liquid coated in the state of the straight tube portion. A high-frequency AC voltage is applied to the terminal block 73 732 through the electric wire 733', and the conductivity (impedance) of the washing liquid existing between the counter electrode portion 739 is measured. Fig. 12 is a view schematically showing the flow of the liquid around the electrode portion 739. Further, in Fig. 12, the electrode portion on the upstream side is attached with a reference numeral of 73%, and the electrode portion on the downstream side is provided with a reference numeral 739b. As shown in Fig. 12, 73% of the pair of electrode portions 73 are bottled along the longitudinal direction of the straight tube portion 01. The plane defined by the axis of the counter electrode portions 739a, 739b is approximately parallel to the axis of the straight f portion. The upstream electrode portion 18 201111581 739a divides the washing liquid flowing along the axis of the straight pipe portion 701 into the upper and lower directions. Therefore, the flow rate of the washing liquid across the plane P is reduced. As a result, in the space between the electrode portions 739a and 739b for measuring the conductivity of the washing liquid (e.g., a space of 15 mm or more and 30 mm or less), the fluidity of the washing liquid is lowered. Further, the flow 0 of the washing liquid suitable for the measurement of the conductivity is obtained. As shown in Fig. 12, the plane P including the axes of the pair of electrode portions 739a and 739b is a horizontal plane. The pair of electrode portions 739a' 739b are preferably not to cross the upper portion of the inner space of the straight tube portion 701 (the drainage control unit 7 may be designed to have a space for air to remain (for example, the upper side of the inner space of the straight tube portion 7〇1) /5 area)) and the lower part of the inner space of the straight pipe part 〇1 (the drainage control unit 7 may be designed to accumulate space of the dirty component (for example, within the straight pipe part 701. Area 5))). As a result, the entire surface of the electrode portion 73 such as the canine portion of 739b is in contact with the washing liquid in the straight tube portion. The influence on the conductivity of the air in the straight tube portion 7 〇 1 can be suppressed. Further, when the electrode portions 739a and 739b protrude in the region of the upper side 4/5 of the internal space of the straight tube portion 70i, the influence on the measurement of the conductivity of the sweat component deposited in the straight tube portion 7〇1 can be suppressed. Fig. 13 schematically shows the flow of the liquid around the photo-sensing device 72 and the electrode sensor 73. Fig. 13 is a view showing the optical path 250 of the infrared light between the light-emitting element 721_optical element 722 of the light sensing n72 in the description of the first battle. Further, similarly to Fig. 12, the electrode is disposed on the upstream side.卩, the reference numeral 739a is attached, and the electrode portion on the downstream side is attached with the reference numeral 19 201111581. In order to prevent unnecessary refraction of the infrared light of the light path 250, the flat inner surface 772 of the inner wall surface of the straight tube portion 7G1 is formed. The upstream end portion π is raised by the other (four) faces, and the upper (four) end portion π disturbs the liquid of the washing liquid "IL. Therefore, in order to adjust the flow of the washing liquid until reaching the optical path 25A, the upper end portion 277 is preferably formed at a position relatively far from the upstream side with respect to the optical path 25A. At this time, the flow path of the measurement of the turbidity of the washing liquid determined based on the amount of the infrared light of the light receiving element 722 of the photosensor 72 described in the seventh to ninth drawings is obtained. The infrared light of the photo sensor 72 does not have any effect on the flow of the washing liquid. Therefore, the flow of the rectified washing liquid reaches the outside of the electrode portions 739a, 73. As explained in Fig. 12, a portion of the flow parallel to the axis of the straight portion 701 is shunted up and down by the upstream electrode portion 739 & As a result, the flow of the washing liquid is disturbed. The disturbance of the liquid flow of the washing liquid caused by the electrode portion 739a is caused to occur closer to the downstream side than the photo sensor 72 described in connection with Figs. 7 to 9, so that the photo sensor 72 is hardly turbid. The degree of measurement has an impact. As will be explained with reference to Fig. 12, the plane P defined by the electrode portion such as the 73% axis is substantially parallel to the axis of the straight tube portion 701. Therefore, for example, when the washing liquid is reversely flowed in the straight pipe portion 701 (the direction from the straight pipe portion 7〇1 to the discharge port 311 of the water tank 31 (see FIG. 1)), the electrode portion 739b causes the washing liquid to be liquid. The flow is divided upward and downward, but the electrode portion 739a overlaps with the electrode portion 739b in the flow direction of the washing liquid. Therefore, the liquid flow of the washing liquid is not excessively disturbed. Therefore, even if the washing liquid is caused to flow backward, the turbidity of the washing liquid passing through the optical path 250 can be sensed with high precision. 201111581 In the lower edge 392 of the boundary between the upper side of the upper side of the flat inner surface 772 and the lower edge 392 defining the lower side of the flat inner surface 772, the I tube portion 1 is bent into a concave cross-sectional contour shape (refer to 7)). In the portion constituting the shape of the cross-sectional profile of the buckling, the liquid flow of the washing liquid is liable to be stagnant more than other portions. As shown in Fig. 13, the electrode portions 739a, 739b are disposed such that a portion of the cross section of the electrode portions 739a, 739b enters the flat inner surface 772. In the vicinity of the upper edge 391 held by the electrode portions 739a and 739b, the washing liquid is particularly likely to be retained. Therefore, a liquid flow suitable for measuring the low fluidity of the conductivity of the washing liquid can be obtained. Further, the plane p defined between the electrode portions 739a and 739b is substantially parallel to the upper edge 391, whereby the measurement accuracy of the conductivity can be further improved. Referring again to Figures 1 through 5. A circulating pump 71 is disposed downstream of the electrode sensor 73. A suction line 711 is disposed between the circulation pump 71 and the casing 7〇 of the drainage control unit 7. The suction line 711 includes one end connected to the suction port of the circulation pump 71, and is connected to the drainage control unit 7. The other end portion of the second opening portion 771 formed by the casing 7 is formed. The second line 52 extending from the discharge port of the circulation pump 71 is connected to the inlet 312 formed in the water tank 31. Fig. 14 is a plan view schematically showing the flow of the washing liquid from the electrode sensor 73 to the circulation pump 7丨. Refer to the figure and figure 2 together with the figure. In Fig. 14, the suction line γη is shown. As shown in Fig. 14, the electrode sensor 73 is not provided in the connection portion 77j of the suction line 711 and the drain control unit 7 (the second opening is shown on the upstream side in Fig. 2; Similarly, in the same manner, the electrode portion disposed on the upstream side is attached with the reference numeral 739a, and the electrode portion disposed on the downstream side is attached with the reference numeral 739b. The straight tube portion 7〇1 and the housing tube of the casing 70 constituting the drainage control unit 7 are provided. The portion 21 201111581 702 forms a straight flow path in plan view (in FIG. 14 , the boundary between the straight tube portion 7 〇 and the accommodating tube portion 702 is indicated by a broken line). The suction line 711 is connected to the straight tube portion 701 and accommodated. The pen line DC path formed by the tube portion 7〇2. The suction pipe 7 ιι is oriented in a direction different from the direction in which the pen DC path formed by the straight pipe portion 701 and the accommodating pipe portion 702 is extended (the structure of the drainage control unit 7 shown in Fig. 14) The middle of the strip is extended in the direction of the right angle. The stripping liquid flowing along the pen line is changed in flow direction by the attraction from the circulating spring 71, and flows toward the suction line 711. The electrode sensor 73 is connected to the connecting portion 771. It protrudes toward the inner surface of the straight pipe portion 7〇1 on the side. The term "the inner surface on the side opposite to the connecting portion 771" means that the straight tube portion 7〇1 and the housing tube portion are separated along the longitudinal direction axis of the straight tube portion and the housing tube portion. The inner surface of the position away from the connecting portion 7 is based on the axis of the suction line 711, for example, located upstream and/or downstream, and is reduced by 3 times to 4 times the inner diameter of the (4) tube material. : accommodating tube portion 7 〇 2 and / or the inner surface area of the straight pipe.

Point _ off-section c (four) relative The position of the material ^771 near the surface (that is, the second end portion of the base end portion (four) of the connection 739b. In the point P1, the electrode portion 739a, the flow force V1 to the cleaning liquid is produced. 22 201111581. Therefore, by disposing the electrode sensor 73 at a position opposed to the connecting portion 771, it is possible to facilitate removal of the cotton fiber stuck in the electrode sensor 73. As described above, the electrode portions 739a, 739b are attached The protruding portion is formed in the straight tube portion 7〇1. Therefore, the cotton fibers contained in the washing liquid flowing into the control unit 7 are easily caught on the electrode portions 739a and 739b. However, the flow force vi is applied to the electrode portions 739a and 739b. The cotton fibers are more easily removed by the electrode portions 739a and 739b. Further, as shown in Fig. 2, a part of the filter portion 76 (see Fig. 1) accommodated in the housing tube portion 7〇2 exists in The electrode sensor 73 is connected between the electrode 771 and the connecting portion 771. In Fig. 14, the weir portion 76 is schematically shown in the mesh region. The washing liquid passes through the electrode sensor 73 existing at the upstream position of the filter portion 76, and passes through the filter disposed in the housing tube portion 702 before reaching the suction line 711 existing at a position downstream of the filter portion 76. Part 76. Therefore, the cotton fibers are collected by the filter portion 76 after being removed by the electrode portions 739a and 73%. Further, since the damper portion 76 has a function of resisting the flow of the washing liquid, the flow of the washing liquid around the electrode portion can be rapidly lowered after the circulation pump 71 is stopped. Fig. 15 is a view for explaining the use of a circulation pump 7 丨 and a drain valve 75 to remove cotton fibers. The 15th (a) diagram schematically shows a plan view of the flow of the washing liquid from the electrode sensor to the circulation pump 71. Figure 15 (b) schematically shows a plan view of the flow of the cleaning fluid from the electrode sensor 73 to the drain valve 75. Refer to Fig. 1 together with Fig. 15. Further, Fig. 15 shows a suction path 711 which forms a flow path to the circulation pump, and a drain line 74 which forms a flow path to the drain valve 75. Further, similarly to Fig. 12, the upstream electrode portion The reference numeral 73% is attached, and the downstream electrode portion is attached with the reference numeral 739b. Further, the 15th (a) diagram is the same as the pattern diagram shown in the i4th diagram, and is used to display the 15th (1?) diagram. Washing 23 201111581 Comparison of the flow patterns of the liquid. As shown in Fig. 15 (a), the electrode sensor 73 is preferably disposed downstream with respect to the connection portion 774 (the second opening portion 774) of the drain line 74, and The connection portion 771 (second opening portion) of the suction path 711 is disposed upstream. With such an arrangement of the electrode sensor 73, in the electrode portion 7 state, 7 highlights the g road flaw, when When the drain valve is opened, the liquid flow of the washing liquid which is reversed when the circulating pump 71 is actuated does not occur as shown in the figure 。 (匕). Moreover, the cotton fibers stuck in the electrode portions 739a, 739b become easy to be The electrode portions 739a and 739b are removed. Fig. 16 shows a circulation system 71. Fig. 16(a) is a cross-sectional view of the circulating milk. Fig. 16(b) is a plan view of the circulation pump 71. Fig. 16(4) is a view of the circulation pump 71 viewed from the suction port side. The circulation pump 71 includes a nut shell forming the outer wall of the circulating pump 71. The pump casing is internally provided with a bearing partition wall 71. The partition wall 714 carries the shell 713 The internal space is divided into two spaces. The space connected to the suction jaw is provided with a thirsty wheel m. A motor 718 is arranged in a space adjacent to the space provided with (4) 717. The motor 718 is suitable for use, for example, a DC brushless motor. The motor shaft 719 is transverse to the bearing partition 714 and extends toward the space in which the turbine 717 is disposed. The turbine 717 integrated with the vehicle 4 partition 714 is supported by the rotating shaft 719. The motor 718 is driven by the motor 718. The turbine 717 rotates together with the bearing partition 714. The chestnut shell 713 is formed with a suction port 715 connected to the suction bow line 711, and a discharge port 716 " and a port 715 and a discharge system connected to the second official path 52. The space of the turbine 717 is provided. 24 201111581 The mounting seat 131 protrudes from the outer surface of the pump casing 713 toward the radial direction. The mounting seat 131 of the circulation pump 71 as shown in Fig. 16 includes the outer scarf s _ Three C-shaped mounting pieces 132. The mounting piece 132 is made The protrusion portion fixed to the bottom holder 712 (see Fig. 1) is attached by a screw. Fig. 17 shows the structure of the connection portion between the water tank 3 and the second conduit 52. Fig. 17 (a) shows the connection portion A plan view of the conduit. Figure 17 (b) is a cross-sectional view of the conduit shown in Figure 17 (a). Figure 17 (c) is a longitudinal section of the conduit shown in Figure p (a). The inlet 312 of the opening 31 is formed by an annular rib 121 that protrudes upward from the outer wall of the water tank 31. An ankle ring U2 is disposed along the inner circumferential surface of the annular rib 121. The ankle ring 122 is pushed by the duct groove 520. The duct groove 520 has a body portion 521 that is bent in an L shape. The body portion 521 includes a conduit 5 22 connected to the second conduit 52 and a lower portion 523 of the lower half conduit 523 extending from the conduit 5 22 toward the inlet 312. The front portion has a configuration and an inlet 312. The opening portion complements the annular projection 525 of the outer peripheral contour. The inside of the annular projection 525 is provided with a pressing wall 123. The pressing wall 123 is curved downward in a curved shape from a substantially central position of the inner space of the annular projection 525, and has a cross section toward the center of rotation of the rotary drum 32. Both ends of the pressing wall 123 are connected to the inner wall surface of the annular projection 525. An annulus 122 is disposed between the annular projection 525 and the annular rib 121. The ankle ring 122 is compressed between the annular projection 525 and the annular rib 121, and functions as a sealing member. The lower half pipe 523 of the duct groove 520 is adjacent to the annular rib 121, and is fixed to the wall portion of the water tank 31 by using the fixture 125 (in the π figure, the pedestal is represented by the fixture 125). Thick part 124. The guide slot 520, in turn, includes a bore 524. The cover 524 and the lower half of the conduit 523 - are deflected by the flow path formed by the conduit 522 to form a flow path toward the inflow opening 312. By the action of the 彳 环 ring pump 71, the second line 52 flows into the inflow port 312 through the conduit groove 520'. Further, the circulation pump 71 is rotated at, for example, a rotation number of 3,500 rpm. A rotating drum 32 is disposed inside the water tank 31. A bearing wall 26 is disposed between the upper surface of the rotary drum 32 and the inflow port 312. The retaining wall 26 is supported by a connecting wall 127 that is coupled to the outer wall of the sink 31. The retaining wall 126 forms a narrow flow path with the extruded wall 123. This narrow flow path functions as an ejection port 129 for injecting the washing liquid into the washing tub 3. The washing liquid passing through the injection port 129 formed by the retaining wall 126 and the pressing wall 123 is then passed through a flow path 281 formed between the end wall 128 of the outer surface constituting the outer surface of the water tank 31 and the front end wall 321 of the rotary drum 32. And supplied to (10) of the rotary drum 32. The front end wall 128 cooperates with the pressing wall 123 to urge the annulus 122. The injection port 129 is formed separately from the rotary drum 32. The laundry in the rotary drum 32 does not contact the ejection opening (3). Therefore, the ejection port 129 hardly adversely affects the washing step, the rinsing step or the lining step. The injection port 129 does not damage the washing material, damages it, and hardly damages the washing material. Further, the flow path 281 downstream of the injection port 129 is taken from the front end wall 128 of the water tank 31 and the front end wall of the rotating drum. Since 32 is formed, it is not necessary to add an additional structure to K. In the configuration shown in Fig. 17, only the ankle ring 122 is used as the sealing member. 1 26 201111581 The front end wall 128 of the water tank 31 and the front end wall 321 of the rotary drum 32 form a loop-shaped outlet portion 282. The washing liquid passing through the flow path 281 passes through the annular outlet portion 282 and is ejected toward the central axis of rotation of the rotary drum 32. The washing liquid sprayed through the outlet portion 282 can be efficiently injected into the inner rotation region of the rotary drum 32. Further, the washing liquid can be efficiently supplied to the laundry irrespective of the amount of the laundry accommodated in the rotary drum 32. The inner surface of the front end wall 128 of the water tank 31 (the surface on which the flow path 281 is formed) includes an inclined surface 283 and a curved surface 284. The inclined surface 283 which gradually reduces the cross-sectional area of the flow path 281 toward the downstream gradually increases the flow velocity of the washing liquid passing through the flow path 281. Therefore, the washing liquid passing through the flow path 281 is accelerated toward the curved surface 284. The curved surface 284 changes the direction of the flow of the washing liquid toward the bottom of the rotating drum 32. Therefore, the washing liquid sprayed from the outlet portion 282 is directed toward the bottom of the rotary drum 32. As a result, the washing liquid can be efficiently supplied to the laundry. The opening of the injection port 129 covers a predetermined range of the circumferential direction of the washing tub 3. The connecting wall 127 and the receiving wall 126 open the injection port 129 in the direction of the central axis of rotation. The connecting wall 127 and the receiving wall 126 hardly disturb the washing liquid flowing into the inflow port 312 and are guided to the flow path 281. The washing liquid is diffused in the circumferential direction to the injection port 129, and then settles into the flow path 281. Then, the washing liquid is further diffused in the circumferential direction and flows to the annular outlet portion 282. Therefore, the washing liquid is ejected from the entire outlet portion 282, and can be stably supplied to the laundry regardless of the amount of the laundry accommodated in the rotary drum 32. The cover 524 of the conduit groove 520 forms a flow path toward the inflow opening 312 using a simple mounting configuration. The shape and size of the cover 21, which covers the cover 524 of the inflow port 312, the shape and size of the connecting wall 127, and the shape and size of the retaining wall 126 are appropriately formed, whereby the appropriate washing liquid can be supplied into the rotary drum 32. By appropriately setting the design parameters of the cover 524, the connecting wall 127, and the retaining wall 126, the flow width, flow thickness, and flow rate of the washing liquid sprayed from the injection port 129 can be appropriately determined. Further, regardless of the amount of laundry accommodated in the rotary drum 32, the soap liquid can be efficiently supplied to the laundry. The mounting structure of the cover 524 of the duct groove 520 shown in Fig. 17, or the very simple structure of the connecting wall 127 and the retaining wall 126 contributes to the suppression of water leakage and the reduction in cost. As described above, the duct groove 520 forms a flow path toward the inflow port 312 in the lower half pipe 523 and the cover 524. As shown in Fig. 1, the flow path formed by the duct groove 520 extends along the outer surface of the water tank 31. Therefore, the lower half pipe 523 and the cover 524 are used, and a small gap between the water tank 31 and the casing 2 forms a flat pipe having a rectangular cross section. The flat pipe is used to define a flow suitable for the shape, size, and thickness of the squirting port 129. The wash liquid passing through the flat line is rectified toward the injection port 129. A plurality of ridges 322 are formed on the front end wall 321 of the rotating drum 32. The ridge 322 extends in a circumferential direction of the front end wall 321 of the rotary drum 32 within a predetermined length. The position of the plurality of ribs 322 in the circumferential direction and the position in the radial direction may be different from each other. The ridge 322 may partially narrow the cross-sectional area of the flow path 28 downstream of the ejection opening 129. In the vicinity of the outlet portion 282, the cross-sectional area of the flow path is narrowed by the ridge 322, and in the case where the cross-sectional area of the flow path is narrowed by the ridge 322 at the exit portion 282, the movement trajectory of the washing liquid ejected from the outlet portion 282 different. Therefore, the washing liquid discharged from the outlet portion 282 oscillates 28 201111581 to a wide range in the rotary drum 32, and the washing liquid is supplied to the laundry with higher efficiency. The shape of the ridge 322 is not limited to that shown in Fig. 17. For example, the ridge 322 may have a wave shape or a blade shape. A rib 322 of any shape that can change the movement trajectory of the washing liquid discharged from the outlet portion 282 can also be used. Further, it is also possible to arrange the protrusions 322 of any shape which can change the movement trajectory of the washing liquid discharged from the outlet 282. A gap 266 is formed between the bearing wall 126 and the rotating drum 32. When the circulation pump 71 is operated at a low speed (for example, 1 OOO rpm), the washing liquid flows into the gap 266 from the injection port 129. The sauce solution flowing into the gap 266 is conveyed toward the discharge port 311 of the water tank 31 in the space between the rotary drum 32 and the water tank 31. Fig. 18 is a diagram showing the functional configuration of the control circuit unit 81. The control circuit unit 81 includes an arithmetic unit 813, a determination unit 814, and a signal transmission unit 815. The calculation unit 813 calculates, for example, the type of the lotion, the concentration of the lotion, and the amount of the soiled component based on the signals from the photo sensor 72 and the electrode sensor 73. The determination unit 814 determines whether or not to execute the predetermined control based on the result calculated by the calculation unit 813. For example, when the amount of the dirty component calculated by the calculation unit 813 exceeds a predetermined threshold, the determination unit 814 causes the signal transmission unit 815 to transmit a signal for operating the water supply system 4 and/or the drainage system 5. The signal transmitting unit 815 receives an instruction from the determining unit 814 and then transmits a signal for operating the water supply system 4 and/or the drain system 5. For example, the signal transmitting portion 815 sends a signal to the solenoid valve signal of the water supply system 4 to turn the solenoid valve on, and sends a signal to the drain of the drain system 5 201111581 valve 75 to open the drain valve. Refer to Fig. 1 together with Fig. 18. A period for determining the state of the washing liquid is set between the washing step and/or the rinsing step. At this time, the control circuit unit 81 transmits a signal (stop signal) for causing the operation of the circulation pump 71 to the circulation pump 71. When the circulation pump 71 is stopped, the flow of the washing liquid in the drain control unit 7 is stopped. As a result, a state suitable for measurement using the photo sensor 72 and/or the electrode sensor 73 is obtained. However, after the stop signal is transmitted, the inertial movement of the circulation pump 71 or the inertial flow of the washing liquid itself may flow, and the flow of the washing liquid in the drain control unit 7 may continue for a predetermined period of time. In the above-described embodiment, since the filter unit 76 is disposed in the vicinity of the sensors 72 and 73, it is possible to suppress the flow of the detergent liquid which is not good after the stop signal is transmitted at an early stage. Therefore, the turbidity and conductivity of the washing liquid can be measured with high precision in a relatively short period of time. In the present embodiment, at the downstream of the sensors 72 and 73, the upstream side of the second opening 771 (connecting portion 771) connected to the suction line 711 shown in Fig. 2 is provided with filtering. Part 76. Therefore, the influence of the inertial motion of the circulation pump 71 or the vibration of the circulation pump 71 can be appropriately moderated by the filter portion 76. Moreover, the turbidity and conductivity of the washing liquid can be measured with higher precision. In the above description, the electrode sensor 73 for measuring conductivity is exemplified as a sensor protruding from the flow path, but the above principle is not limited thereto, and may be applied to any one that must be in direct contact with the washing liquid. A washing machine that senses the physical properties of the washing liquid. In the above description, the photo sensor 72 is used to measure the turbidity of the washing liquid, but it can also be used for other measurement purposes. The above principles can also be applied to the photosensor 72' for sensing the accumulation of soiled components or other physical or environmental changes that can be suitably measured using the optics 72. (1) In the above description, the flow device for causing the washing liquid to flow is a pump, and instead, the propeller disposed in the circulation path or the flow path may be used, but the polyester liquid flows. ' Loss of σ from the looming washing machine. The washing machine of the above embodiment - the washing machine comprises: a washing tank having a discharge port for discharging the washing strip; a pipe connected to the discharge port; a suction pipe extending in a direction different from the extension of the pipe, so that the above-mentioned washing secret flows from the discharge port toward the suction path: a sense of the secret of the test before the test, and ^: the characteristic of the heart is attracted by the aforementioned The inner surface of the pipeline and the first two opposite sides of the pipeline protrudes. The nozzle of the moving device of the eyelet is operated to wash the outlet of the knee_extending the suction pipe to reduce the connection route, the pipe and the suction bow The manifold is equipped with the flow force of the pipeline to the suction pipeline. The contact materials of the sensor ^, the road and the suction pipe are opposite to each other. Because of the production; In the direction of the connection, the suction force of the cotton fiber will be removed from the surface of the sensor, and the sensor will be placed at a position opposite to the connection between the pipe and the suction. The removal of the cotton fiber from the sensor can be accommodated. According to the above configuration, the conductivity of the washing liquid is measured by the sensor to sense the type of the lotion or the concentration of the lotion contained in the washing liquid. As described above, since the removal of the cotton fibers can be promoted by the sensor, the influence of the conductivity of the cotton fibers on the measurement can be reduced. Further, as the cotton fibers are removed, the electrode portions which are largely protruded in the washing liquid can be used. The conductivity is measured with high precision. In the above configuration, the sensor is preferably disposed in a flow of the sacrificial liquid exposed to the first flow direction of the suction line from the discharge port, and is opposite to the first flow direction. According to the above configuration, the sensor can be easily exposed to the washing liquid in the second flow direction by the cotton fiber which is difficult to remove in the washing liquid in the first flow direction. In the above configuration, it is preferable to further have a drain pipe connected to the pipe and discharging the washing liquid to the outside, and the drain pipe is located in the aforementioned connection of the suction pipe The portion is located closer to the upstream of the first flow direction, and the sensor is located closer to the upstream of the first flow direction than the connection portion, and is located closer to the first flow direction than the connection portion between the conduit and the drain line According to the above configuration, the flow of the washing liquid around the sensor between the drain and the outside of the washing liquid by the drain line becomes the flow of the washing liquid in the first flow direction during the operation of the flow device. The liquid flow of the washing liquid in the second flow direction is reversed. Therefore, the washing liquid is discharged by the discharge line, whereby the cotton fiber stuck in the sensor can be easily removed. 32. Further, the filter unit for removing the dirt component contained in the washing liquid is disposed, and the filter unit is disposed in the vicinity of the sensor. According to the above configuration, the cotton fiber removed by the protruding portion can be collected by the filter unit. Since the filter portion acts as a resistance to the liquid flow of the washing liquid flowing in the pipe, the degree of the flow of the washing can be reduced in a short time after the flow device is stopped, and even if the feeling is used When the physical properties of the washing liquid are easily affected by the liquid flow of the washing liquid, the physical properties of the washing liquid can be measured in a short time and with high precision. In the above configuration, at least a portion of the filter portion is preferably present between the sensor and the connecting portion of the suction line. According to the above configuration, the filter portion acts to resist the flow of the washing liquid between the connection portion between the sensor and the suction pipe. Therefore, the influence of the flow return from the perfusion liquid can be alleviated. Further, even if the physical properties of the washing liquid are measured by the sensor, the physical properties of the washing liquid can be measured with high precision. In the above configuration, the conduit preferably includes a straight portion protruding from the sensor, and a housing tube portion connected to the straight tube portion and the suction duct and housing the filter portion, and the storage tube portion is opposite to the aforementioned The straight tube is tilted upwards. According to the above configuration, the air bubbles that have flowed into the straight tube portion are pushed into the housing tube portion, and it is difficult to return from the housing tube portion. Therefore, it is difficult for the air bubbles to be stored in the straight pipe portion, and even if the physical properties of the washing liquid are measured by the sensor, it is easily affected by the presence of air bubbles in the pipe, and the washing liquid can be measured at a short time and with high precision. Conductivity. In addition, the water head of the storage tube will be used to suppress the flow of unnecessary washing liquid caused by the inertial movement of the flow device after the signal of the flow device is stopped, so even if the sensor is used to measure the washing liquid The physical properties are easily affected by the flow of the washing liquid, and the physical properties of the washing liquid can be measured with high precision.
