Description of the Invention: Field of the Invention: Field of the Invention The present invention relates to a washing machine capable of controlling the washing operation in response to the degree of soiling of the washing liquid. BACKGROUND OF THE INVENTION A conventional washing machine is provided with a dirt sensor capable of detecting a state of a washing liquid, such as a conductivity sensor, in a water tank, and the washing stroke control is performed by detecting a state such as laundry water dirt, and reveals Japanese Patent Publication No. 4-187183 (Patent Document 1). Fig. 6 is a view for explaining the relationship between the degree of soiling in the washing process of the conventional washing machine described in Patent Document 1 and the control of the washing process with respect to the degree of soiling. In Fig. 6, Vlf is the electrical conductivity V at the initial stage of the washing and agitating which is detected by the conductivity sensor provided in the lower portion of the tank including the washing and dewatering tank, and is subtracted from the end of the washing and stirring. The value of the electrical conductivity Vf. Further, the degree of contamination is determined by the value of Vlf of each water level, and the washing process is controlled in accordance with the increase or decrease of the washing time or the strength of the water flow in response to the degree of soiling. A conventionally constructed washing machine can measure the degree of soiling of the washing liquid by measuring the conductivity of the washing liquid by a conductivity sensor. However, the electrical conductivity changes greatly depending on the type of contamination. If the degree of contamination is detected only by electrical conductivity, the following problems will occur. That is, the conductivity sensor has a large electrical conductivity when measuring water containing salt. Therefore, in the case of laundry which is mainly composed of sweat and the like, it is judged that the dirty 201200674 is sufficiently washed with a large degree of dirt such as mud. However, in the case of another body washing matter, even if the actual degree of pollution is serious, the conductivity sensor will detect a small electrical conductivity, and there will be a stain such as dirt. (4) The problem of less pollution (4) The law of riding fully washed.

送風部61或給水閥70等的支持構件71。 給水閥70係由2個以上之水路可開閉的複數閥所構 成’並由自來水或洗澡水吸水機構(未圖示）所供給。此時， 一側之水路係構成為縮小閥的張開面積或洗淨管7 2側的吐 出口面積而流通小流量的水。一側的水路係透過洗淨管 72 ’連接至水槽43之外底部排水管75所形成的洗淨軟管 77。而另一側的水路則係構成為加大閥的張開面積或給水 管73側之吐出口面積而流通大流量的水。另一側的水路係 藉由給水管73,透過設置於支持構件71之注水構件（未圖示） 等連接於内槽44而可供給洗衣水。 又’在上部框體68内方之支持構件71，設有可收納可 使用複數次洗衣量的液體洗劑、並可自動投入液體洗劑於 外槽43内的液體洗劑自動投入裝置64。此外，液體洗劑自 動投入裝置64與外槽罩65係以具可撓性的洗劑注水管59所 連接。藉由空氣泵等（未圖示），由液體洗劑自動投入裝置64 壓送的液體洗劑係透過洗劑注水管59滴入外槽43與内槽44 之間。另外，藉由洗劑注入管59的可撓性，在脫水時，即 使做為振動系統之外槽43全體振動旋轉，也可減低對振動 系統或洗劑注水管59的影響。 在外槽43底部，設有可排出外槽仙之水的排水間 74。排水閥74透過排水f 75連接於熱交好邱接續管 53。來自於接續管53與敏換管52的排水由排水管75、排 201200674 水閥74所引導，從排水管76排至洗衣機外。此外，如前所 述，於排水管75之洗淨軟管77，連接有配管於給水閥7〇之 洗淨管72的一端。 又，在排水管75之排水閥74上游，安裝有濁度檢測部 92，其係將例如放射可視光或紅外線等光線之LED或雷射 等之發光元件、與光電二極體或光電晶體等受光元件相對 設置者。濁度檢測部92藉由通過存在於相對之發光元件與 受光元件之間之水或洗衣水的光線透過度或變化率，檢測 水及洗衣水的濁度，而檢測衣類的髒污程度。 並且，在排水管75的外面，設有第3溫度檢測部97，可 檢測排水管75内的水溫，亦即連通外槽43内、由給水間7〇 所給水的洗衣水的水溫。 在外槽43的底部附近，設有具有一對電極94的導電率 檢測部78。且’導電率檢測部78可檢測出洗衣水的導電率， 由溶解於水的副離子等檢測出污垢的被洗淨程度，並藉由 組抗值的變化檢測出水之有無等。此時，由於在外槽幻下 部、較波輪46外周部上面更下方處設有導電率檢測部78， 故可不受到波輪46旋轉之水流影響，而可安定地檢測出洗 衣水的導電率。 又，在外槽43的外周壁，設有氣阱95，該氣阱95透過 空氣官96連接於由壓力感測器等所構成之水位檢測部9〇。 水位檢測部90可藉由供給至外槽43内部之洗衣水的水壓，

以下，使用第2圖說明本實施型態洗衣機之控制裝置的 動作及機能。 在第2圖中，控制裝置8〇具有負荷驅動部％與控制部 87。負何驅動部86可控制馬達(驅動部）48、離合器49、構成 /jbl風送風。卩61之乾燥用風扇55及加熱器％、排水閥μ、冷 卻用送風機（冷卻部）79、給水_、吸水栗91、^氣果4〇 等的動作。控制部87可透過負荷驅動部86，控制洗淨行程、

所輸入没定的設定内容。此外，控制部87透過由雙向閘流 體、繼電器專所構成的負荷驅動部86，控制馬達48、離合 器49、乾；^用風扇55、加熱器56、排水閥74、冷卻用送風 機79、給水閥70、吸水泵91、空氣泵4〇等的動作，控制洗 201200674 淨、漂洗、脫水、乾燥的各行程。 又’控制部87可根據由導電率檢測部78所得之洗衣水 的導電率、或者是由濁度檢測部92所得之光線透過率或變 化率’檢測出洗衣水的有無、洗劑的種類或衣類的辨污程 度等，而控制各行程。 在此，導電率檢測部78係由一對電極94'水檢測電路 98和污垢檢測電路99、切換前述2個檢測電路98和99的繼電 器100所構成。而且，水檢測電路98若藉由繼電器1〇〇與電 極94連接’則可作為從電極94所檢測之電導度（導電率)檢測 出有無洗衣水的水位感測器而產生機能。另—方面，污垢 檢測電路99若藉由繼電器丨〇〇與電極94連接，則可作為檢測 出污垢程度的污垢感測器而產生機能。 並且’控制部87在乾燥行程中，當第2溫度檢測部63所 檢測出的溫度達到第1預定溫度(例如1贼）時，關掉加熱器 56、。然後’控制部87在當從上述第1預定溫度下降至第2預 疋恤度(例如低2 C的溫度)時，進行㈣，使加熱^ 調節循環風的溫度。 =所述’㈣本實施型態之洗衣機的各行程，並進

可因應布量進行後述之洗滌波輪攪拌1)的水位，第9段為最 高水位。 如第3圖所示’洗蘇動作（洗;條行程）的基本行程係由洗 淨行程、漂洗⑴行程、漂洗⑺魏、脫水行程所構成。' 如第4圖所示，首先，行程開始運轉（si〇i)，以布量檢 測部93檢測出所投入的布量_小此時，控制部以暫時決 定因應布量之水位、洗劑量之多寡及以後的程序，將水位、 洗劑量顯示於顯示箱⑻阶另外，#開始運轉時，藉由 鎖蓋裝置(未圖示）固定外蓋69,若不按下輸入設定部83的暫 時停止按鈕(未圖示）’則外蓋69無法開閉。 同時，小流量的給水閥70進行動作，開始給水至洗淨 管72側（給水b)。藉此’在預定時間内，將可充滿排水管乃 的水量給水至洗淨軟管77到排水管如（讓）。然後，以濁 度檢測部92檢測出所給予的自來水濁度d〇，取得所檢測出 的濁度輔料(_)，將前述資料輪人至控制部87。 另外，使小W量之給水閥7〇動作而給水的理由係：若 使大流量的給水_進行動作(給水，透過給水管乃將自 來水給予至内槽44内，則由於自來水會通過髒衣物而積在 排水管75，因此無法檢測出正確的自來水濁度D0。但是， 本實施如上所述，使小流量的給水閥鶴作，從洗 201200674 淨軟管77側給予少量的自來水，故可不混入衣類等的污垢 而正確地檢測出自來水ί蜀度D0。 接著，因應顯示於顯示部84的洗劑量，投入洗劑 (S106)。另外，投入洗劑可能會有兩種情形：使用者因應顯 示於顯示部84之洗劑量而投入粉末洗劑或液體洗劑、以及 藉由液體洗劑自動投入裝置64自動投入液體洗劑。在本實 施型態中，係以使用者投入粉末洗劑或液體洗劑為例來進 行說明。 然後，當投入洗劑，在給水b程序中，使小流量的給水 閥70動作，透過洗淨管72、洗淨軟管77，通過排水管75、 接續管53，從下側給水至槽内直到第丨段水位為止（sl〇7)。 另外’第1段水位係指較波輪46的外周部上面略低1〇〇mm、 導電率檢測部78可浸到水裡的小容量水位。 接著，以導電率檢測部78之水檢測電路98檢測水位 (S108) ’若檢測出第1段水位，即停止給水(sl〇9)。另外， 一般洗衣機在檢測水位時，係採用較廉價的方式，使用以 設置於外槽43之氣阱95所受壓的水壓而進行檢測的水位檢 測部90。但是，以水壓進行檢測的方式難以正確地檢測出 較波輪46外周上面略低1 〇〇mm、水壓非常小的最低段水 位。因此’若藉由導電率檢測部78之水檢測電路98檢測水 位’由於在導電率檢測部78的一對電極94接觸到水時即可 檢測出水位，故即使最低段的水位也可正確檢測。 而後，進行用以溶解洗劑的槽旋轉動作（S110)。槽旋轉 動作係指在關閉排水閥74的狀態下’將傳達機構部之離合 12 201200674 器49切換至脫水側，將馬達48的動力透過洗淨、脫水軸45 傳達至内槽44而進行旋轉。具體而言，使内槽44與波輪仆 同時以50〜120rpm前後的低速旋轉。藉此，槽内的洗衣水 可藉離心力作用在内槽44與外槽43之間慢慢地旋轉，因此 洗衣水不會附著於衣類’而洗劑也可充分地溶解、起泡。 接著，停止槽旋轉，取得濁度檢測部92所檢測出之濁 度Di(sm)。此時，首先，以濁度檢測部92檢測洗衣水加 入洗劑後的濁度D1的初期值。同時，切換繼電器1〇〇，連接 至導電率檢測部78之污垢檢測部99，取得導電率（電導 度)E1(S112)。另外，上述濁度D1之初期值係指來自於衣類 之污垢尚未被抽出之狀態的洗衣水濁度。然後，將洗衣水 濁度D1的初期值資料輸入至控制部87，以控制部87藉由 判定(S0 = D1 —DO)演算’排除在步驟S1〇5取得D〇時所取得 之自來水濁度D0，而演算濁度值。藉此，例如藉由濁度判 定所投入之洗劑為粉末洗劑或液體洗劑等的洗劑種類。然 後，控制部87因應所判定之洗劑種類，決定並控制之後的 洗淨行程及/或漂洗行程時間（Si 13)。 接著，給水至第2段水位，並在關閉排水閥74的狀態 下，將傳達機構部的離合器49切換至脫水側’將馬達48的 動力透過洗淨、脫水軸45傳達至内槽44而使之旋轉。使内 槽44與波輪46—起以較步驟S11〇更低的速度（35rprn左右） 旋轉(給水、槽旋轉)(S114)。然後，在槽旋轉停止後，給水 至第3段水位（給水a)(sll5)。 接著’藉由傳達機構部的離合器49，將馬達48的動力 13 201200674 透過洗淨、脫水軸45傳達至波輪46，藉由波輪46的旋轉， 進行波輪揽拌a(S 116)。然後，更給水至第4〜5段水位（給水 a)(S117) ’進行波輪銳掉a(S118)。此時，給水時之第2段水 位以上的複數水位檢測係由壓力式水位檢測部9〇所進行。 藉由上述動作，以比標準水位(在本實施型態中為藉由 布量檢測所設定之第9段水位)低的水位(在本實施型態中為 咼水位低4段的水位）’進行所謂的洗劑高濃度授拌。藉此， 洗劑可事先充分地溶解，並且也可充分地起泡，衣類的污 垢可有效地溶解於洗衣水中。 接著，停止波輪攪拌a，取得以濁度檢測部92所檢測出 的濁度D2(S119)。同時，藉由導電率檢測部78之污垢檢測 電路99,取得洗衣水的導電率（電導度)£2,進行污垢檢測（洗 衣水的濁度）(S120)。然後，將低於高水位之較低水位的洗 衣水濁度D2資料輸入至控制部87，演算攪拌時間（S121)。 接著，使大流量的給水閥70動作，透過給水管73，對 於内槽44給水至標準水位（例如，第3、4圖的情況係給水至 高水位（第9段))(給水a)(S122)。 然後，當給水結束’開始進行由控制部87演算（S121) 而決定之時間（例如’粉末洗劑則為8分鐘、液體洗劑為1〇 分鐘）的洗滌波輪攪拌b(S123)。 然後，當洗滌波輪授拌b開始，因為波輪46的旋轉，衣 類會被波輪46之攪拌用突出部51絆住而被拉往中心部。此 時’内槽44之中心下層部的衣類會因為被拉住的衣類而被 向上推至内槽44的上層部。如此一來，可攪拌内槽料内的 14 201200674 衣類，藉由衣類間或者與内槽44内部或波輪46之接觸所作 用的機械力與水流力，衣類所包含的污垢會溶出於洗淨水 中。結果，洗淨水的濁度會依序變化。 接著，以預定之標準水位（第6〜9段）開始洗淨行程中之 洗務波輪權摔b之後’也以濁度檢測部92進行洗衣水之濁度 D3檢測與資料的取得(S124)。同時，藉由導電率檢測部78 之污垢檢測電路99 ’進行洗衣水之導電率（電導度)E3的污 垢檢測與資料取得（S125)。 然後，以控制部87進行取得濁度Dl(Slll)和取得濁度 D2(S119)所檢測出之資料、與取得濁度D3(S124)所檢測出 之資料的S2判定(S2 = D3-D2或D3-D1)與演算(S126)。同 樣地’以控制部87進行取得導電率（電導度)E1(S112)和取得 導電率（電導度)E2(S120)所檢測出之資料、與取得導電率 (電導度)E3(S 125)所檢測出之資料的T2判定(T2 = E3 — E2 或E3 —E1)與演算(S126)。 此外，控制部87根據82及了2判定進行演算，從洗衣水 的髒污私度，判定洗滌物的污垢除去程度(si26)。另外使 用第5圖’說明如何判定後述洗衣水的髒污程度 、即從衣類 除去污垢的程度。 藉此’根據洗條物之除去污垢程度的判定結果，修正 m#·時間而進行波輪攙拌b(si27)。又，根據洗務物 之除去辟&度的狀結果，進行下-練之漂洗⑴行程 中的漂洗（1)攪拌c。 、下使用第3圖及第4圖詳細說明漂洗⑴行程。 15 201200674 首先如第3圖所*，開啟排水閥74 ’藉由排水管76排 出内槽44内的水。然後’將傳達機構部之離合H49切換至 脫水側1騎48的動力透職淨、脫水軸Μ傳達至内槽 而進行方疋轉藉此，給予衣類離心力進行使水分從衣 類脫離的脫水步驟。然後，在給水a，大流量之給水閥70進 灯動作、，.σ水至向水位（第9段）。之後，再度驅動馬達狀， 為了使洗舰攸衣射洗出，根據步驟si〗崎判定之洗務 物之除去污垢&度的判定結果，如第所示，開始漂洗⑴ 攪拌c(S128)。 藉由以上，結束漂洗（1)行程。 接著進行以下所示之最終漂洗行程的漂洗⑺行程。 首先如第3圖所示，與漂洗⑴行程一樣進行排水、脫 水及給水a。然後’根據步觀26_定之洗_之除去污 垢程度的判定結果，如第4圖所示，進行漂洗⑺撥掉 c(S129) ’藉此結束漂洗(2)行程。 接著，在脫水行程，漂洗(2)行程結束後，開啟排水閥 74 ’藉由排水管76排出内槽44的水。然後，將傳達機構部 之離合器49切換至脫水側，將馬達48的動力透過洗淨、脫 水轴45傳達至内槽44而進行旋轉。藉此，使衣類藉由離心 力進行分離脫水(S130)。 ,以下，使用第5圖說明如何判定洗衣水的髒污程度、即 攸衣類除去污垢的程度。 —般而言，衣類的污垢有汗垢或泥垢等各種污垢。並 且’當藉^線的透過程度進行檢狀濁度檢剛部％在檢 201200674 測例如汗垢時，即使很多汗垢，洗衣水的濁度也較小，所 以難以進行適當的判定。另一方面，當藉由洗衣水的導電 率（電導度）進行檢測之導電率檢測部7 8在檢測例如汗垢溶 出而含有鹽份的水時，導電率（電導度）的變化會變大，因此 會判疋出與貫際髒污程度相同、鱗污程度較為嚴重的結 果。所以’可判定為從衣類充分除去污垢。 但是，在泥垢的情況下，洗衣水雖較為混濁，但導電 率（電導度）的變化較小。因此，雖可以濁度檢測部92正確地 判定污垢已被洗出，但難以以導電率檢測部78進行適當判 定。 因此，若綜合地判斷由濁度檢測部與導電率檢測部2個 污垢檢測料狀㈣，财判定洗衣水_污程度、即 從衣類除去污垢的程度。 第5圖係顯示本實施型態洗衣機之濁度之辦污程度與 導電率（電導度)之程度的相_矩陣圖。 另外，第5圖之縱軸表示藉由濁度檢測部9 2所取得之i蜀 度的辦污㈣果，肋鐵D_L4麵洗衣水的

The automatic detergent device 64 is further connected to the outer tank cover 65 by a flexible detergent water injection pipe 59. The liquid detergent or the like (not shown) automatically The liquid lotion which is fed by the input device 64 is dropped between the outer tank 43 and the inner tank 44 through the lotion water injection pipe 59. Further, by the flexibility of the lotion injection pipe 59, even when it is dehydrated, it is vibrated. The entire outer groove 43 of the system vibrates and rotates, and the influence on the vibration system or the lotion pipe 59 can be reduced. At the bottom of the outer tank 43, there is a drainage chamber 74 which can discharge the water of the outer tank. The drain valve 74 is connected to the heat exchange loupe connection pipe 53 through the drain f 75. The drain from the splice pipe 53 and the miner pipe 52 is guided by the drain pipe 75, the row 201200674 water valve 74, and discharged from the drain pipe 76 to the outside of the washing machine. Further, as described above, the washing hose 77 of the drain pipe 75 is connected to one end of the washing pipe 72 which is piped to the water supply valve 7'.

The light receiving element is opposite to the set. The turbidity detecting unit 92 detects the degree of soiling of the clothes by detecting the turbidity of the water and the washing water by the light transmittance or the rate of change of the water or the washing water existing between the light-emitting elements and the light-receiving elements. Further, on the outer surface of the drain pipe 75, a third temperature detecting portion 97 is provided to detect the water temperature in the drain pipe 75, that is, the water temperature of the washing water that communicates with the water supplied from the water supply chamber 7 in the outer tank 43.

Further, the conductivity detecting unit 78 can detect the conductivity of the washing water, detect the degree of cleaning of the dirt by the side ions dissolved in the water, and the like, and detect the presence or absence of water by the change in the group resistance. At this time, since the conductivity detecting portion 78 is provided at the lower portion of the outer groove and the lower portion of the outer peripheral portion of the pulsator 46, the conductivity of the washing water can be stably detected without being affected by the flow of the water of the pulsator 46. Further, a gas trap 95 is provided on the outer peripheral wall of the outer tank 43, and the air trap 95 is connected to the water level detecting portion 9A constituted by a pressure sensor or the like through the air member 96. The water level detecting unit 90 can detect the water level in several stages (for example, 1 to 9 stages) by the water pressure of the washing water supplied to the inside of the outer tank 43. Further, the control device 80 controls the respective devices, and is configured by a load drive 201200674, which is described later, and a control unit 87, and is slightly staggered (including vertical) along the back surface portion (the inner cover) 81 of the casing 41. It is disposed on the upper side of the cooling blower 79. And (4) the device is covered by the cover 82 for protection. above. The other surface of the p-frame 68 is provided with an operation display unit 85 composed of an input setting unit and a display unit 84 (described later in Fig. 2). Hereinafter, the operation and function of the control device for the washing machine of this embodiment will be described using Fig. 2 . In Fig. 2, the control unit 8A has a load drive unit % and a control unit 87. The negative drive unit 86 can control the motor (drive unit) 48, the clutch 49, and the /jbl air supply. The drying fan 55 and the heater %, the drain valve μ, the cooling blower (cooling unit) 79, the water supply _, the water pump 91, and the gas juice 4 are operated. The control unit 87 can control the washing stroke, the rinsing stroke, the dehydration stroke, the strokes of the Laiyun rhyme, and the g and deodorization strokes through the load driving unit 86. The control unit 87 is constituted by, for example, a microcomputer, and starts operation when the power switch _ ONB Temple' k commercial power source 88 supplies electric power. Thereby, the output data of the input setting unit 83 'the amount detecting unit 93, the water level detecting unit 9〇, the second temperature detecting unit 62, the second temperature detecting unit 63, and the third temperature detecting unit 97 are input to the control unit 8. The display unit 84 of the operation display unit 85, which is composed of the input setting (4) and the display list, displays the setting contents that the user inputs through the input setting unit 83. Further, the control unit 87 controls the motor 48, the clutch 49, the dry motor, the heater 56, the drain valve 74, the cooling blower 79, and the water supply valve through the load drive unit 86 including the two-way thyristor and the relay. 70. The operation of the water suction pump 91, the air pump 4, etc., controls the strokes of the washing, washing, dehydrating, and drying of 201200674. Further, the control unit 87 can detect the presence or absence of the washing water, the type of the lotion, or the type of the washing agent based on the conductivity of the washing water obtained by the conductivity detecting unit 78 or the light transmittance or rate of change obtained by the turbidity detecting unit 92. The degree of discrimination of clothing, etc., and control of each trip. Here, the conductivity detecting unit 78 is composed of a pair of electrodes 94' water detecting circuit 98, a dirt detecting circuit 99, and a relay 100 that switches the two detecting circuits 98 and 99. Further, if the water detecting circuit 98 is connected to the electrode 94 by the relay 1', it can function as a water level sensor for detecting the presence or absence of the washing water from the electrical conductivity (conductivity) detected by the electrode 94. On the other hand, if the dirt detecting circuit 99 is connected to the electrode 94 via the relay port, it can function as a dirt sensor that detects the degree of dirt. Further, the control unit 87 turns off the heater 56 when the temperature detected by the second temperature detecting unit 63 reaches the first predetermined temperature (for example, one thief) during the drying process. Then, the control unit 87 performs (4) when the first predetermined temperature is lowered from the first predetermined temperature (for example, a temperature lower than 2 C), and the heating is performed to adjust the temperature of the circulating air. = (4) Each stroke of the washing machine of the present embodiment, and (4) Figs. 3 and 4, illustrating the water in the present embodiment:: hair: the implementation of the washing machine from the washing stroke to the fourth drawing The system is different from the flow chart of the control of the washing machine from the washing course 201200674 to the dehydration stroke. In the following description, a case where the amount of cloth is large and the water level is set to a high water level (ninth stage) will be described as an example. Here, the water level is set to increase sequentially from the i-th stage to the ninth stage, and is lower than the low water level on the outer peripheral portion of the pulsator 46 until the third stage. Further, in the fourth to ninth stages, the water level of the washing wheel pulsator 1) which will be described later can be performed in accordance with the amount of the cloth, and the ninth stage is the highest water level. As shown in Fig. 3, the basic stroke of the washing action (washing; strip stroke) consists of a washing stroke, a rinsing (1) stroke, a rinsing (7) Wei, and a dehydration stroke. As shown in Fig. 4, first, the stroke starts to operate (si〇i), and the amount of cloth to be fed is detected by the cloth amount detecting unit 93. When the amount is small, the control unit temporarily determines the water level and the washing amount for the cloth. The number of water level and washing dose are displayed on the display box (8). In addition, when the # start operation, the cover 69 is fixed by a lock device (not shown), and the temporary setting of the input setting unit 83 is not stopped. The button (not shown) 'the cover 69 cannot be opened and closed. At the same time, the small-flow water supply valve 70 is actuated to start supplying water to the side of the cleaning pipe 72 (feed water b). By this, the amount of water that can be filled with the drain pipe is supplied to the washing hose 77 to the drain pipe for a predetermined time. Then, the turbidity detecting unit 92 detects the supplied tap water turbidity d〇, acquires the detected turbidity auxiliary material (_), and sends the data wheel to the control unit 87. In addition, the reason why the water supply valve 7 of the small amount of W is operated to supply water is to operate the water supply _ (water supply, the tap water is supplied to the inner tank 44 through the water supply pipe, since the tap water passes through the dirty clothes) Since it is accumulated in the drain pipe 75, the correct tap water turbidity D0 cannot be detected. However, as described above, the small-flow water supply valve crane is used, and a small amount of tap water is given from the side of the washing 201200674 net hose 77, so The tap water is appropriately detected and the tap water temperature D0 is accurately detected. Next, the lotion is supplied in response to the washing amount displayed on the display unit 84 (S106). In addition, there may be two cases in which the lotion is applied: the user responds The washing agent or the liquid lotion is introduced into the washing amount displayed on the display portion 84, and the liquid lotion is automatically introduced by the liquid lotion automatic introducing device 64. In the present embodiment, the user applies the powder lotion or The liquid lotion is exemplified as an example. Then, when the lotion is introduced, in the water supply b program, the small-flow water supply valve 70 is operated, the cleaning tube 72 is passed, the hose 77 is washed, and the drain pipe 75 is passed. The splicing pipe 53 feeds water from the lower side to the water level in the tank until the water level of the second stage (sl 〇 7). In addition, the 'water level of the first stage means a distance lower than the outer circumference of the pulsator 46 by 1 〇〇 mm, and the conductivity detecting portion 78. The water level detecting circuit 98 detects the water level (S108). When detecting the water level, the washing machine uses a relatively inexpensive method and uses the water level detecting unit 90 that detects the water pressure applied to the air trap 95 provided in the outer tank 43. However, it is difficult to correctly detect the water pressure. The lowest water level which is slightly lower than the outer circumference of the pulsator 46 by 1 〇〇mm and the water pressure is very small is detected. Therefore, 'the water level is detected by the water detecting circuit 98 of the conductivity detecting unit 78' because the conductivity detecting unit 78 When the pair of electrodes 94 are in contact with water, the water level can be detected, so that even the lowest water level can be correctly detected. Then, the tank rotating operation for dissolving the lotion is performed (S110). The groove rotating operation means that the drain is closed. In the state of valve 74, the mechanism will be conveyed The clutch 12 201200674 is switched to the dehydrating side, and the power of the motor 48 is transmitted to the inner tank 44 through the washing and dehydrating shaft 45 to rotate. Specifically, the inner groove 44 and the pulsator are simultaneously rotated at 50 to 120 rpm. Therefore, the washing water in the tank can be slowly rotated between the inner tank 44 and the outer tank 43 by centrifugal force, so that the washing water does not adhere to the clothes, and the lotion can be sufficiently dissolved and activated. Then, the groove is rotated to obtain the turbidity Di(sm) detected by the turbidity detecting unit 92. At this time, first, the turbidity detecting unit 92 detects the initial value of the turbidity D1 after the washing water is added to the lotion. At the same time, the switching relay 1 is connected to the dirt detecting unit 99 of the conductivity detecting unit 78 to obtain the conductivity (electrical conductivity) E1 (S112). Further, the initial value of the turbidity D1 refers to the turbidity of the washing water from the state in which the dirt of the clothing has not been extracted. Then, the initial value data of the laundry water turbidity D1 is input to the control unit 87, and the control unit 87 calculates (S0 = D1 - DO) calculus 'excluding the tap water turbidity obtained when the D 取得 is obtained in the step S1 〇 5 D0, and calculate the turbidity value. Thereby, for example, the lotion to be determined by the turbidity determination is a lotion type such as a powder lotion or a liquid lotion. Then, the control unit 87 determines and controls the subsequent washing course and/or the rinsing stroke time (Si 13) in accordance with the determined type of the lotion. Then, the water is supplied to the second stage water level, and the clutch 49 of the transmission mechanism unit is switched to the dehydrating side while the drain valve 74 is closed. The power of the motor 48 is transmitted and the dewatering shaft 45 is transmitted to the inner tank 44. Rotation. The inner groove 44 is rotated together with the pulsator 46 at a lower speed (about 35 rprn) than the step S11 ( (water supply, groove rotation) (S114). Then, after the rotation of the tank is stopped, the water is supplied to the third water level (feed water a) (sll5). Then, by the clutch 49 of the transmission mechanism unit, the power 13 201200674 of the motor 48 is transmitted to the pulsator 46 through the washing and dewatering shaft 45, and the pulsator 46 is rotated to perform the pulsator a (S116). Then, the water is supplied to the water level of the 4th to 5th (water supply a) (S117)', and the pulsator is sharply a (S118). At this time, the plurality of water level detections of the second water level or more in the case of water supply are performed by the pressure type water level detecting unit 9A. By the above operation, the water level lower than the standard water level (in the present embodiment, the water level of the ninth stage set by the cloth amount detection) is lower than the water level of the fourth stage water level in the present embodiment. The so-called lotion is mixed at a high concentration. Thereby, the lotion can be sufficiently dissolved in advance, and also sufficiently foamed, and the stain of the clothes can be effectively dissolved in the washing water. Then, the pulsator a is stopped, and the turbidity D2 detected by the turbidity detecting unit 92 is obtained (S119). At the same time, the conductivity (electrical conductivity) of the washing water is obtained by the dirt detecting circuit 99 of the conductivity detecting unit 78, and the dirt is detected (the turbidity of the washing water) (S120). Then, the washing water turbidity D2 data lower than the lower water level of the high water level is input to the control unit 87, and the stirring time is calculated (S121). Next, the large-flow water supply valve 70 is operated to pass the water supply pipe 73, and the inner tank 44 is supplied with water to a standard water level (for example, in the case of Figs. 3 and 4, the feed water to the high water level (ninth stage)) (feed water a) (S122) ). Then, when the water supply is completed, the washing pulsator stirring b (S123) is started when the control unit 87 calculates (S121) and the time is determined (for example, the powder lotion is 8 minutes and the liquid lotion is 1 minute). Then, when the washing pulsator b starts, the clothes are caught by the stirring projections 51 of the pulsator 46 and pulled toward the center portion by the rotation of the pulsator 46. At this time, the clothing of the lower portion of the center of the inner groove 44 is pushed up to the upper portion of the inner groove 44 by the clothes to be pulled. In this way, the 14 201200674 garments in the inner tank can be stirred, and the mechanical strength and water flow force acting between the garments or the inner tank 44 or the pulsator 46 can dissolve the dirt contained in the clothes. In the water. As a result, the turbidity of the washing water changes sequentially. Then, the turbidity detecting unit 92 performs the turbidity D3 detection of the washing water and the acquisition of the data by the turbidity detecting unit 92 after the predetermined standard water level (stages 6 to 9) is started. ). At the same time, the dirt detection circuit 99' of the conductivity detecting unit 78 performs the contamination detection and data acquisition of the conductivity (conductivity) E3 of the washing water (S125). Then, the control unit 87 performs the acquisition of the data detected by the turbidity D1 (S111) and the acquired turbidity D2 (S119), and the S2 determination of the data detected by the acquired turbidity D3 (S124) (S2 = D3-D2). Or D3-D1) and calculation (S126). Similarly, the control unit 87 performs the data obtained by obtaining the conductivity (electrical conductivity) E1 (S112) and the obtained conductivity (electrical conductivity) E2 (S120), and the obtained conductivity (conductivity) E3 (S 125). The T2 decision (T2 = E3 - E2 or E3 - E1) and the calculation (S126) of the detected data. Further, the control unit 87 performs calculation based on the determination of 82 and 2, and determines the degree of soil removal of the laundry from the dirtyness of the washing water (si26). Further, how to determine the degree of soiling of the washing water described later, that is, the degree of removing dirt from the clothes, will be described using Fig. 5'. By this, the pulsator b (si27) is calibrated based on the result of the determination of the degree of soil removal by the strip. Further, rinsing in the lower-practice rinsing (1) rinsing in the stroke (1) stirring c is performed based on the result of the removal of the laundry and the degree of the grading. The rinsing (1) stroke will be described in detail using Figs. 3 and 4. 15 201200674 First, as shown in Fig. 3, the drain valve 74' is opened to drain the water in the inner tank 44 by the drain pipe 76. Then, the clutch H49 of the communication mechanism unit is switched to the power-dissipation of the dehydration side 1 ride 48, and the dehydration shaft is conveyed to the inner tub to perform the rotation, thereby imparting a centrifugal force to the clothes to perform a dehydration step of separating the moisture from the clothes. Then, in the feed water a, the large-flow water supply valve 70 is actuated, and the σ water reaches the water level (ninth stage). After that, the motor is again driven, and in order to wash and wash the washing machine, the result of the determination of the dirt removal and the degree of removal of the laundry determined in the step si, as shown in the first step, starts the rinsing (1) stirring c (S128) . By the above, the rinsing (1) stroke is ended. The rinsing (7) stroke of the final rinse stroke shown below is then carried out. First, as shown in Fig. 3, drainage, dehydration, and water supply a are performed in the same manner as the rinsing (1) stroke. Then, based on the determination result of the degree of removal of the stain according to the step 26_, as shown in Fig. 4, the rinsing (7) is performed by dialing c (S129)' to end the rinsing (2) stroke. Next, after the dehydration stroke and the rinsing (2) stroke are completed, the drain valve 74' is opened to discharge the water in the inner tank 44 by the drain pipe 76. Then, the clutch 49 of the transmission mechanism unit is switched to the dehydration side, and the power of the motor 48 is transmitted to the inner tank 44 through the cleaning and dehydration shaft 45 to be rotated. Thereby, the clothes are separated and dehydrated by centrifugal force (S130). Hereinafter, how to determine the degree of soiling of the washing water, that is, the degree of removal of the dirt by the clothing, will be described using Fig. 5. In general, the dirt of clothing has various dirt such as sweat or mud. Further, when the degree of penetration of the turbidity is detected by the degree of transmission of the turbidity, the turbidity of the washing water is small even if there is a lot of sweat, and it is difficult to make an appropriate determination. On the other hand, when the conductivity detecting unit 78 that detects the conductivity (electrical conductivity) of the washing water detects, for example, water containing salt eluted by sweat, the change in electrical conductivity (electrical conductivity) becomes large. Therefore, it is judged that the result is the same as the degree of internal contamination and the severity of the scale. Therefore, it can be judged that the dirt is sufficiently removed from the clothes. However, in the case of mud, the washing water is turbid, but the change in electrical conductivity (conductivity) is small. Therefore, the turbidity detecting unit 92 can accurately determine that the dirt has been washed out, but it is difficult to appropriately determine the conductivity detecting unit 78. Therefore, when it is determined that the turbidity detecting unit and the conductivity detecting unit have two types of dirt detecting materials (4), it is determined that the degree of washing water _ staining, that is, the degree of removing dirt from the clothes. Fig. 5 is a phase diagram showing the phase of the degree of turbidity of the washing machine of this embodiment and the degree of electrical conductivity (conductivity). Further, the vertical axis of Fig. 5 indicates the contamination (i) of the i 蜀 degree obtained by the turbidity detecting unit 92, and the privilege of the rib iron D_L4 surface washing water is added. Further, the horizontal axis of Fig. 5 shows the (four) degree of contamination by the conductivity (electrical conductivity) of the conductivity detecting portion of the conductivity detecting portion. Fruit <e_lhL4 table * Laundry water (four) increased the degree of contamination. As shown in Fig. 5, the degree of contamination obtained by the two dirt detecting units is comprehensively determined from T-L1 to T-L4. Specifically, S, example, 〇,,, g ΐίτ BM* The degree of turbidity and dirt is judged as D - L1 is slightly lesser, the conductance is meager and the sturdy is 4 is determined by the strict division. The final degree is T 17 201200674 The degree of the joint is T -L4 is a serious dirt. At this time, it was judged that the sweat stain had been detached from the clothing having a severe sweat. In addition, when the degree of turbidity is judged as D_L3, the degree of dirt, the degree of contamination of the conductance is also determined to be in the middle of the _L3, and the smear is the middle of the T-L3. At this time, it is judged that moderate sweat or mud is detached from the clothes. That is, based on the results of the comprehensive determination of the S2 determination result and the 12 determination result, it is judged whether or not the dirt has sufficiently detached from the clothing. And, control the washing process, extend or shorten the washing time after the washing wheel b (S127), or extend or shorten the rinsing (1) stroke sanding c (S128) and rinsing (2) stroke rinsing (mixing e ( For example, according to the order of tu, T-L2'TL3 TT4, T-L3, T_L4, the washing time is increased. Or, according to T-L1, T-L2, T τ 2 ττ/ΐΑ·- 丄In the order of T-L3 and T-L4, the rinsing time is set to be longer, etc. As described above, first, in the washing course, the turbidity detecting unit detects the turbidity of the washing water to determine the degree of soiling. The conductivity detecting unit detects the electrical conductivity of the washing water to determine the degree of soiling. Then, based on the two kinds of determination results of turbidity and electrical conductivity, it is finally determined whether the degree of staining, that is, whether the dirt has sufficiently detached from the clothing, and further, based on the final determination. As a result, the control unit controls, for example, the washing stroke, the rinsing stroke, and the dehydration stroke. At this time, the electric potential is detected. A very low water level that is difficult to detect by the dust level water level detecting unit is usually detected. In addition, only add relays and - part of the dirt detection The road can share the water level detection and the dirt detection to form the conductivity detecting unit. As a result, the conductivity detecting unit having a low cost and a simple structure 18 201200674 can be realized. According to the embodiment, the reliability is high. It is possible to determine the degree of soiling with high precision, and it is possible to achieve a washing machine having an excellent washing performance by setting a washing stroke or a rinsing stroke at an appropriate time.
