Description of the invention [Technical field to which the invention belongs] The present invention relates to a drum-type washer having a rotary groove rotating around the outer periphery of the horizontal axis. [Prior art] A drum-type washing machine having a The horizontal groove is a horizontally rotating slewing trough and a water trough accommodating the slewing trough, and a plurality of baffles are provided on the inner surface of the trough wall portion of the slewing trough to raise the laundry. In the washing operation and the washing operation, the rotary tank is rotated while water is stored in the water tank and the laundry is stored in the rotary tank, and the laundry is dropped after the laundry is lifted. Thereby, the aforementioned laundry can be beaten and washed. In the dehydration operation, the rotation speed of the rotation tank is gradually raised to the highest speed by rotating the rotation tank at a low speed and after the water contained in the laundry flows out to a certain degree, the centrifugal dehydration of the laundry is performed. In the drum type washing machine, once the laundry is put on one side in the rotary tub, the state concentrated on one side is difficult to eliminate during the washing process. In particular, when the laundry is positioned on either of the left and right sides of the rotary tub, a large amount of vibration is generated during the dehydration operation. Therefore, in the conventional drum type washing machine, a liquid weight is provided in order to suppress a large amount of vibration and noise caused by the deflection concentration of the laundry, and in order to eliminate the deflection of the laundry in the direction of the groove axis, at the beginning of the dehydration operation At low speed, the slewing trough is formed to rotate forward and backward alternately. However, the above method has a problem that it cannot sufficiently suppress vibration and noise in a large drum-type washing machine with large washing capacity. In response to the above problems, in order to suppress the concentration of the laundry in the direction of the groove axis in a drum type washing machine provided with a groove axis facing the front-rear direction of the washing machine and forming a sloping groove inclined upward, a method other than a baffle is proposed. The structure of a secondary baffle is set at the end plate behind the rotary groove. Once the aforementioned rotary tank is tilted forward and upward, the laundry will be easily concentrated on the innermost part. According to the above-mentioned configuration, since the deflected concentrated laundry existing in the innermost part of the rotary tank can be sufficiently stirred, the occurrence of uneven washing can be suppressed.

The laundry which becomes heavy due to the water content at the end of drainage is located in the lower part of the rotary tank 14. According to this, when the rotary tank 14 is rotated at a low speed, the laundry is repeatedly lifted and dropped by the main dampers 20 to 22. As a result, the water contained in the laundry is removed to a certain extent. Next, the control microcomputer drives the motor to rotate the rotary tank 14 in a single direction at a rotary speed of about 60 to 8 Orpm. At this time, the laundry in the revolving tank 14 is moved into the revolving tank 14 by the main baffle plates 20 to 22 and the sub baffle 23, and is evenly attached to the entire tank wall portion. In other words, although the laundry located near the center in the axial direction in the rotary tank 14 is lifted by the main baffle 20 to 22, the centrifugal force acting on the laundry is divided into a part attached to the wall of the tank and Falling @ 分. As shown in FIG. 5, if the distance from the rotation center axis 0 of the rotation tank 14 to the center of gravity of the laundry S is r, the mass of the laundry S is m ′, and the rotational angular velocity is ω, which acts on the washing in the rotation tank 14 The centrifugal force F of the object S is defined as follows:
F m X r X ω 2 (1) -12- 200532068 (9) 如上述計算式（1 )所示，離心力F與距離r形成一定比 例。舉例來說，如第6圖所示，當迴轉槽1 4內存有大量 的洗滌物S時，位於外周部的洗滌物S 1與位於內周部的 洗滌物S2將如第6圖中的r 1、r2所示，從迴轉軸1 4之 迴轉中心Ο算起的距離變得不同（rl >1*2)。據此，作用於洗 滌物S 1的離心力將大於作用於洗滌物S2的離心力。因 此，藉由主擋板20〜22上揚的洗滌物中，原本位於外周部 B 的洗滌物將不會落下地貼附於槽壁部’而原本位於內周部 的洗滌物將形成落下。如此一來’迴轉槽1 4內的洗滌 物，將緩緩地分散而平均地貼附於全體的槽壁部。 相對於此，位於迴轉槽1 4之軸方向兩側的洗滌物， 由於去除水份後變輕，將藉由副擋板23而上揚。此時， 由於副擋板23爲三角錐狀，因此洗滌物可藉由傾斜面23a 移動至迴轉槽14的軸方向中央附近，並藉由傾斜面23b 從附擋板2 3的外周方向兩側移動至迴轉槽1 4的軸方向中 ^ 央附近。如此一來，洗滌物將集中於迴轉槽1 4的軸方向 中央附近。被集中於迴轉槽1 4之軸方向中央附近的洗滌 物，將藉由上述主擋板20〜22的作用而平均地貼附於迴轉 槽1 4的整個槽壁部內面。 如上所述地，迴轉槽1 4內的洗滌物將依序分散於整 個槽壁部的內面，可降低不平衡的狀態。此外，由於上述 的動作，將使得位於迴轉槽1 4之軸方向中央附近的洗滌 物量多於位在兩端附近（端板附近）的洗滌物量。 當控制用微電腦判定洗滌物已平均地貼附於迴轉槽1 4 -13- 200532068 (10) 的槽壁部時，將驅動馬達使迴轉槽1 4的迴 約1 0 0 r p m左右。而洗條物是否平均貼附於 部的判斷，舉例來說，是藉由偵測迴轉槽在 程中馬達迴轉速度的變動（亦即迴轉波形） 該迴轉速度（lOOOrpm)，是設定成使作用於迴 全體洗滌物的離心力超出重力加速度的迴車專 在上述狀態中，迴轉槽1 4是在迴轉槽〗4內 貼附於槽壁部的狀態下迴轉。 在此之後，控制用微電腦將驅動馬達而 至900〜1200rpm的最筒速度。如此一·來，洗 於槽壁部內面的狀態下與迴轉槽1 4 一起迴 心脫水。此外，當因爲迴轉槽1 4的迴轉速虔 升至最高迴轉速期間所出現的複數個共振點 動時，控制用微電腦將降低迴轉速度以促使 的洗滌物移動，來執行修正造成共振動原因 •作 。接著，修正上述的不平衡狀態後，將再度 的迴轉速度上升至最高速度。 接下來，參考第5圖說明發生於脫水運 發生於脫水運轉時之振動的大小是由加振力 力的大小，則是取決於加諸在洗滌物S的離 洗滌物S之重心周圍的慣性矩（moment of 與通過振動系統重心之前述迴轉中心軸〇形 G，而從面G到洗滌物S重心爲止的距離爲 轉速度上升至 迴轉槽之槽壁 迴轉一周之過 的方式進行。 轉槽14內之 速度。據此， 之全體洗滌物 使迴轉槽上升 滌物將在貼附 轉，而形成離 [從 1 OOrpm 上 而造成大量振 迴轉槽1 4內 之不平衡的動 :使迴轉槽1 4 轉時的振動。 所決定。加振 心力與作用於 inertia ) 〇 當 成垂直的面爲 L時，慣性矩 -14- 200532068 (11) Μ被定義如下： Μ = FxL= mxrx ω 2xL......(2) 如上所述，F是作用於洗滌物的離心力。如上述計算 式（2 )所示，慣性矩Μ與距離r及距離L形成比例。此 外，如以上所述，離心力F與距離r形成比例。據此，造 成存在迴轉槽1 4軸方向中心附近之不平衡的振動，將小 於造成存在迴轉槽1 4軸方向兩端部之不平衡的振動。 p 在本實施例中，由於洗滌物被集中於迴轉槽1 4的軸 方向中央附近，而使得迴轉槽1 4內的軸方向附近，亦即 振動系統的重心附近存在不平衡。據此，相較於迴轉槽軸 方向端部發生不平衡的傳統滾筒式洗衣機，可降低發生於 脫水運轉時的振動。 在烘乾運轉中，控制用微電腦將驅動馬達使迴轉槽1 4 以低速迴轉於正反方向上，並驅動乾燥裝置。藉此，可將 熱風化後的空氣供給至迴轉槽1 4內而帶走洗滌物所含有 φ 的水分。此外，對帶走水分的空氣除濕，並於形成熱風化 後，再度供給至迴轉槽1 4內。藉由上述的空氣循環使迴 轉槽1 4內的洗滌物形成乾燥。 此外，藉由迴轉槽1 4低速迴轉於正反方向上，迴轉 槽14內的洗滌物將藉由主擋板20〜22上揚，並藉由通過 迴轉槽1 4內的熱風擴散落下於迴轉槽1 4內。此外，副擋 板2 3可使擴散落下於迴轉槽1 4內的洗滌物移動至迴轉槽 1 4的軸方向中央附近。換言之，迴轉槽1 4內的洗滌物將 一邊被分散、集中，一邊移動至迴轉槽14內。因此，通 -15- (12) (12)200532068 過迴轉槽1 4內的熱風將有效率地與洗滌物形成接觸，可 提高乾燥效率。 此外’根據本案發明人的實驗可得知，藉由以主擋板 2 0〜22及副擋板23攪拌洗滌物，可降低烘乾結束時洗滌物 產生扭纏和糾結。 第7圖’是比較具有主擋板2 0〜22及副擋板23的滾 筒式洗衣機（在第7圖中以P表示）、及僅具有主擋板 20〜22的滾筒式洗衣機（在第7圖中以Q表示）於烘乾結 束時之布料糾結率的直方圖（histogram)。在第7圖中，橫 軸表示洗條物量’縱軸表示布料糾結率。 虽配合卽拍(metronome)的節奏（rhythm)，且每次 從迴轉槽1 4內取出一件洗滌前及洗滌後的洗滌物（由乾 木棉布所形成）的狀態下，取出全部洗滌物所需的平均時 間分別爲T 0 (秒）、T1 (秒）時，布料糾結率τ ( % )可 由以下的計算式（3 )求出。 T = {^^〇-)}xl〇〇......... ( 3 ) 由第7圖可淸楚得知，具有副擋板2 3的滾筒式洗衣 機可較不具有副擋板2 3的滾筒式洗衣機降低布料糾結 率。 根據本實施例，藉由於迴轉槽1 4設置副擋板2 3，可 於脫水運轉時使迴轉槽1 4內的洗滌物移動至軸方向的中 心附近，也就是振動系統的重心附近。因此，可抑制發生 於脫水運轉時的振動與噪音。此外，由於藉由前述副擋版 23能有效率第使位於迴轉槽1 4之軸方向兩端部的洗滌物 -16 - 200532068 (13) 移動至軸方向中央附近，故可縮短修正不平衡動作的時 間。 此外，在烘乾運轉中，藉由主擋板20〜22與副擋板23 的合作可使洗滌物一邊重複形成分散、集中，一邊移動至 迴轉槽1 4內。特別是本實施例中，由於副擋板23是設置 成從主擋板20〜22處分離，故主擋板20〜22與副擋板23 能有效地合作而使洗滌物移動。因此，可提高乾燥效率並 _ 降低洗滌物的布料糾結。此外，根據本發明團隊的實驗可 得知，採用具有副擋板23的滾筒式洗衣機執行洗滌，烘 乾結束時洗滌物的皺折量低。這點也能淸楚地從烘乾運轉 時之布料糾結率低的結果得知，根據上述的結構，也具有 可以在良好狀態下完成對洗滌物淸洗的效果。 第 8圖，是顯示本案發明團隊針對副擋板的存在與 否、及副擋板之尺寸的不同，而於脫水運轉時所發生之振 動差異的實驗結果。在第8圖中橫軸表示洗滌物的重量， φ 縱軸表示振動的振幅。此外，第8圖中折線P 1〜P4是表示 變更副擋板23的尺寸的實驗結果，折線Q表示不具副擋 板23時的實驗結果。而折線 P1〜P4，是分別以「H2 = 60mm; Hl=40mm」、「H2=60mm; Hl=65mm」、「H2 =100mm ; Hl = 40mm」、「H2 = 100mm ; Hl = 65mm」作 爲副擋板23之軸方向長度H2與高度HI的實驗結果。 由第8圖可淸楚得知，無論是哪一個具有主擋板 2 0〜22及副擋板23的滾筒式洗衣機於脫水運轉時所產生的 振動振幅，均小於僅具主擋板20〜22之滾筒式洗衣機於脫 -17- 200532068 (14) 水運轉時所產生的振動振幅。此外，在具有副擋板2 3的 滾筒式洗衣機中，以折線P4所示的滾筒式洗衣機，亦即 具有「H2=100mm; Hl=65mm」尺寸之副擋板23的滾筒 式洗衣機的振動振幅最小。換言之，在本實施例中，藉由 將副擋板23的尺寸設定爲上述尺寸，可獲得極高的降低 振動效果。 而本發明並不侷限於上述的實施例，可具有如以下所 _ 述的衍生例。 副擋板2 3的高度及軸方向的長度並不侷限於上述的 實施例。第9圖及第1 0圖，是爲了調查副擋板23之高度 的差異所造成的振動振幅差異、副擋板23之軸方向長度 的差異所造成的振動振幅差異，而根據第8圖的實驗結果 所作成的圖。 亦即，第9圖是根據具有軸方向長度爲60mm之副檔 板23的滾筒式洗衣機的實驗結果（對應於第8圖中的折線 φ P1及P2)所製成，其橫軸表示副擋板23的高度，縱軸則 表示相對於不具副擋板23的滾筒式洗衣機（對應於第8圖 中的折線Q)之振動振幅的下降量。此外，第1 0圖是根據 具有高度爲40mm之副擋板23的滾筒式洗衣機（對應於第 8圖中的折線P1及P3)所製成，其橫軸表示副擋板23的 軸方向長度，縱軸則表示相對於不具副擋板2 3的滾筒式 洗衣機之振動振幅的下降量。此外，第9及第1 0圖的折 線K 1〜K 4，是根據洗漉物量爲1 k g、3 k g、5 k g、8 k g時的 資料所製成。 •18- 200532068 (15) 由第9、1 0圖可淸楚得知，副擋板23的高度Η1越 大，或者軸方向的長度Η2越大’振動的降低量也大。但 是，基於脫水運轉時所發生的振動振幅通常爲〇.5mm左右 誤差値，當振動的降低量超過〇 · 5mm時，其降低振動的效 果才具有意義。接著，經執行實驗之4個範例的洗滌物量 中，至少有2個範例的振動降低量爲〇 · 5 mm以上而形成極 大的振動降低效果，其副擋板2 3的形狀’是形成高度約 30mm以上，軸方向長度約50mm以上。 副擋板2 3的高度，將影響使洗滌物上揚的作用’並 與洗滌物的厚度相關。據此’由於洗滌物一般的厚度約爲 3 0mm，因此副擋板的高度最好爲30mm以上。 副擋板2 3的軸方向長度’將影響使位於迴轉槽1 4之 軸方向端部的洗滌物朝振動系統中心移動的作用’而迴轉 軸1 4之軸方向的長度與迴轉槽1 4端部至振動系統重心爲 止的距離相關。在上述實施例中，由於迴轉槽1 4的軸方 向長度爲400mm，從迴轉槽的端板至重心爲止的距離爲 2 0 0mm，所以可獲得良好降低振動效果之副擋板23的軸 方向長度，最好爲迴轉槽I4之軸方向長度的8分之1以 上，而端板至重心爲止的距離最好爲4分之1以上。但 是，副擋板2 3必須配置在槽壁部內面上從迴轉槽端板至 面G爲止間的範圍內。 此外，設置於迴轉槽之軸方向兩端側的副擋板即使未 形成相對狀亦無妨。再者，副擋板只需設置在靠近迴轉槽 端板的槽壁部即可，無須與前述端板形成接觸。 -19- 200532068 (16) 在迴轉槽之迴轉中心軸朝前上方傾斜的滾筒式洗衣機 中，由於迴轉槽內的洗滌物是偏向集中於下方，也就是迴 轉槽內的最涂部（後方），故最好將副擋板設置在迴轉槽 之槽壁部上靠近後方端板。 在振動系統的重心從迴轉槽軸方向中心偏移的滾筒式 洗衣機中，最好使沿著軸方向呈相對狀的一對副擋板形成 不同的軸方向長度。換言之，當重心位於迴轉軸之軸方向 _ 中心的其中一側邊時，最好使配置於槽壁部之軸方向其中 一側之副擋板的軸方向長度，較配置於另一側之副擋板的 軸方向長度更短。但是，各副擋板必須配置在通過重心的 面G與端板之間的範圍內。 副擋板，亦可藉由對迴轉槽的槽壁部或者端板施以沖 壓加工的方式形成。根據上述的構成方式，可使副擋板與 迴轉槽形成一體，而可輕易地組裝。 副擋板並不侷限於三角錐狀，舉例來說，亦可形成半 φ 圓錐狀。 本發明也能適用於前面具有洗滌物出入口的滾筒式洗 衣機。 【圖式簡單說明】 第1圖：顯示本發明的滾筒式洗衣機之一種實施例的 全體結構外觀斜視圖。 第2圖：滾筒式洗衣機的縱剖面圖。 第3圖：顯示省略滾筒蓋的迴轉槽斜視圖。 -20- 200532068 (17) 第4圖：副擋板的放大斜視圖。 第5圖：用來說明作用於位在迴轉槽內之外周部洗滌 物的離心力、與作用於位於內周部之洗滌物的離心力間差 異的圖。 第6圖：用來說明作用於洗滌物之離心力與重心旋轉 之慣性矩大小的圖。 第7圖：說明因副擋板的存在與否，於乾燥完成時布 料糾結率之差異的圖。 第8圖··說明因副擋板的存在與否、及副擋板的尺寸 大小’於脫水運轉時所發生之振動差異的圖。 第9圖：說明因副擋板的高度差異，而產生不同振動 振幅的圖。 第1 〇圖：說明因副擋板23軸方向長度的差異導致振 動振幅不同的圖。 【主要元件符號說明】 1 :滾筒式洗衣機 I 〇 :水槽 II :懸吊裝置（制振支承裝置） 14 :迴轉槽 15 :槽軸 2〇〜22 :主擋板 23 :副擋板 23a 、 23b :傾斜面 -21 -F m X r X ω 2 (1) -12- 200532068 (9) As shown in the above formula (1), the centrifugal force F and the distance r form a certain ratio. For example, as shown in FIG. 6, when there is a large amount of laundry S in the rotary tank 14, the laundry S 1 located at the outer periphery and the laundry S 2 located at the inner periphery will be as r in FIG. 6. 1. As indicated by r2, the distance from the rotation center 0 of the rotation axis 14 becomes different (rl > 1 * 2). Accordingly, the centrifugal force acting on the laundry S1 will be greater than the centrifugal force acting on the laundry S2. Therefore, in the laundry lifted by the main baffles 20 to 22, the laundry originally located on the outer peripheral portion B will be attached to the tank wall portion without falling down, and the laundry originally positioned on the inner peripheral portion will form a drop. In this way, the laundry in the 'rotating tank 14 is gradually dispersed and uniformly adhered to the entire tank wall portion. On the other hand, the laundry on both sides in the axial direction of the rotary tank 14 becomes lighter after removing water, and will be lifted by the sub-baffle 23. At this time, since the sub-baffle 23 is a triangular cone shape, the laundry can be moved to the vicinity of the center in the axial direction of the rotary tank 14 by the inclined surface 23a, and from both sides of the outer peripheral direction with the baffle 23 by the inclined surface 23b. Move to the center of the rotary groove 14 in the axial direction. In this way, the laundry will be concentrated near the center in the axial direction of the rotary tank 14. The laundry concentrated in the vicinity of the center in the axial direction of the rotary tank 14 will be evenly adhered to the entire inner surface of the tank wall portion of the rotary tank 14 by the action of the main baffles 20 to 22 described above. As described above, the laundry in the rotary tank 14 is sequentially distributed on the inner surface of the entire tank wall portion, so that an unbalanced state can be reduced. In addition, due to the above-mentioned operation, the amount of laundry located near the center in the axial direction of the rotary tank 14 is greater than the amount of laundry located near both ends (near the end plate). When the control microcomputer determines that the laundry is evenly attached to the tank wall portion of the rotary tank 1 4 -13- 200532068 (10), the drive motor will return the rotary tank 14 to about 100 r p m. The determination of whether the strips are evenly attached to the part is, for example, by detecting a change in the rotation speed of the motor during the rotation groove (ie, the rotation waveform). The rotation speed (1000 rpm) is set to make the effect In the above-mentioned state, the carriage return that the centrifugal force of the entire laundry exceeds the acceleration of gravity is in the above-mentioned state, and the rotation groove 14 is rotated in a state where the rotation groove 4 is attached to the groove wall portion. After that, the control microcomputer will drive the motor to a maximum barrel speed of 900 to 1200 rpm. In this way, it is dehydrated with the rotary tank 1 4 while being washed on the inner surface of the tank wall. In addition, when the number of resonance jogging occurs during the revolving speed of the rotary tank 14 to the highest revolving speed, the control microcomputer will reduce the revolving speed to promote the movement of the laundry, and perform correction to cause the cause of the common vibration. Make. Then, after correcting the above-mentioned unbalanced state, the turning speed is increased again to the maximum speed. Next, with reference to FIG. 5, it is explained that the magnitude of the vibration that occurs during the dehydration operation during the dehydration operation is caused by the vibration force, and it depends on the inertia around the center of gravity of the laundry S from the laundry S. The moment of and the center of rotation G of the aforementioned rotation center axis passing through the center of gravity of the vibration system are 0, and the distance from the surface G to the center of gravity of the laundry S is such that the rotation speed rises to one revolution of the tank wall of the rotary tank. The speed within 14. According to this, the entire laundry will make the rotary trough rise, and the polyester will rotate on the attachment, which will cause a large number of unbalanced movements in the rotary trough 14 from 100 rpm. 1 4 Vibrations at rotation. Determined. Vibration force and action on inertia) 〇 When the vertical plane is L, the moment of inertia -14-200532068 (11) Μ is defined as follows: Μ = FxL = mxrx ω 2xL .. .... (2) As mentioned above, F is the centrifugal force acting on the laundry. As shown in the above formula (2), the moment of inertia M is proportional to the distance r and the distance L. In addition, as described above, the centrifugal force F is proportional to the distance r. As a result, the unbalanced vibration near the center in the 4-axis direction of the rotary groove 14 is smaller than the unbalanced vibration in the two-axis ends of the rotary groove 14 in the axial direction. p In this embodiment, because the laundry is concentrated near the center in the axial direction of the rotary tank 14, there is an imbalance near the axial direction in the rotary tank 14, that is, near the center of gravity of the vibration system. As a result, compared with the conventional drum-type washing machine in which the end portion in the direction of the axis of the rotary groove is unbalanced, it is possible to reduce the vibration that occurs during the spin operation. During the drying operation, the control microcomputer rotates the rotary tank 14 in the forward and reverse directions at a low speed, and drives the drying device. Thereby, the hot weathered air can be supplied into the rotary tank 14 and the moisture φ contained in the laundry can be taken away. In addition, the air that has taken away moisture is dehumidified, and after being subjected to thermal weathering, it is supplied to the rotary tank 14 again. The laundry in the revolving tank 14 is dried by the above-mentioned air circulation. In addition, by rotating the rotary tank 14 in the forward and reverse directions at a low speed, the laundry in the rotary tank 14 will be lifted by the main baffle 20 ~ 22, and will fall to the rotary tank by the hot air passing through the rotary tank 14 1 4 within. In addition, the auxiliary baffle plate 23 can move the laundry diffused in the rotary tank 14 to the vicinity of the center of the rotary tank 14 in the axial direction. In other words, the laundry in the rotary tank 14 is moved into the rotary tank 14 while being dispersed and concentrated. Therefore, the hot air passing through -15- (12) (12) 200532068 through the rotator 14 will effectively come into contact with the laundry, and the drying efficiency can be improved. In addition, according to the experiments of the inventor of the present case, it can be learned that by agitating the laundry with the main baffle 20 to 22 and the sub baffle 23, it is possible to reduce tangling and tangling of the laundry at the end of the drying. Fig. 7 'compares a drum type washing machine (shown as P in Fig. 7) having a main baffle plate 20 to 22 and a sub baffle plate 23 and a drum type washing machine having only a main baffle plate 20 to 22 (in The 7 is represented by Q) a histogram of the tangled rate of the cloth at the end of drying. In Fig. 7, the horizontal axis represents the amount of washed strips and the vertical axis represents the kink rate of the cloth. Although in accordance with the rhythm of the metronome (rhythm), and each time a piece of laundry (made of dry kapok cloth) before and after washing is taken out from the rotary tank 14, take out all the laundry When the required average times are T 0 (seconds) and T1 (seconds), the cloth entanglement rate τ (%) can be obtained from the following calculation formula (3). T = {^^ 〇-)} xl〇〇 ...... (3) As can be clearly seen from FIG. 7, the drum type washing machine with the auxiliary baffle 23 may be less equipped with the auxiliary baffle. The drum type washing machine of the plate 2 3 reduces the tangled fabric rate. According to this embodiment, since the sub-baffle plate 23 is provided in the rotary tank 14, the laundry in the rotary tank 14 can be moved to the vicinity of the center in the axial direction, that is, near the center of gravity of the vibration system during the dehydration operation. Therefore, it is possible to suppress vibration and noise occurring during the dehydration operation. In addition, the auxiliary gear 23 can efficiently move the laundry -16-200532068 located at both ends in the axial direction of the rotary tank 14 (13) to the vicinity of the center in the axial direction, so that the correction of unbalanced motion can be shortened. time. In addition, during the drying operation, the cooperation of the main baffle plates 20 to 22 and the sub baffle plate 23 allows the laundry to be repeatedly distributed and concentrated while being moved into the rotary tank 14. In particular, in the present embodiment, since the auxiliary baffle 23 is provided to be separated from the main baffle 20 to 22, the main baffle 20 to 22 and the auxiliary baffle 23 can effectively cooperate to move the laundry. Therefore, it can improve the drying efficiency and _ reduce the tangled fabric. In addition, according to the experiments of the team of the present invention, it is known that washing is performed using a drum type washing machine having a secondary baffle 23, and the amount of wrinkles of the laundry at the end of drying is low. This also makes it clear from the result that the tangled rate of the cloth during the drying operation is low. According to the above-mentioned structure, the effect that the laundry can be washed in a good state can also be achieved. Fig. 8 shows the experimental results of the present invention team regarding the presence or absence of the auxiliary baffle and the difference in the size of the auxiliary baffle during the dehydration operation. In FIG. 8, the horizontal axis represents the weight of the laundry, and the vertical axis φ represents the amplitude of vibration. In addition, the broken lines P1 to P4 in FIG. 8 are the experimental results showing the change in the size of the auxiliary baffle 23, and the broken line Q indicates the experimental results when the auxiliary baffle 23 is not provided. The polylines P1 to P4 are supplemented by "H2 = 60mm; Hl = 40mm", "H2 = 60mm; Hl = 65mm", "H2 = 100mm; Hl = 40mm", and "H2 = 100mm; Hl = 65mm". Experimental results of the length H2 and the height HI of the baffle 23 in the axial direction. It can be clearly seen from FIG. 8 that the vibration amplitude generated by the drum type washing machine having the main baffle plates 20 to 22 and the second baffle plate 23 during dehydration operation is smaller than that of only the main baffle plate 20 to 20 (22) The vibration amplitude generated when the drum-type washing machine of 22 is dewatered. In addition, in the drum type washing machine having the secondary baffle 23, the vibration amplitude of the drum type washing machine shown by the fold line P4, that is, the drum type washing machine having the secondary baffle 23 having a size of "H2 = 100mm; Hl = 65mm" The smallest. In other words, in this embodiment, by setting the size of the sub baffle 23 to the above-mentioned size, an extremely high vibration reduction effect can be obtained. The present invention is not limited to the above-mentioned embodiments, and may have derivative examples as described below. The height of the sub baffle 23 and the length in the axial direction are not limited to the above-mentioned embodiment. 9 and 10 are for investigating the difference in vibration amplitude caused by the difference in the height of the sub-baffle 23 and the difference in the vibration amplitude caused by the difference in the length of the sub-baffle 23 in the axial direction. Figures made from experimental results. That is, FIG. 9 is based on the experimental results of a drum-type washing machine having an auxiliary baffle plate 23 having an axial length of 60 mm (corresponding to the broken lines φ P1 and P2 in FIG. 8), and the horizontal axis represents the auxiliary gear The vertical axis of the height of the plate 23 indicates the amount of decrease in vibration amplitude with respect to the drum-type washing machine (corresponding to the broken line Q in FIG. 8) without the sub-baffle 23. In addition, FIG. 10 is based on a drum type washing machine having a secondary baffle 23 with a height of 40 mm (corresponding to the polylines P1 and P3 in FIG. 8), and the horizontal axis represents the axial length of the secondary baffle 23. The vertical axis represents the amount of decrease in vibration amplitude with respect to the drum-type washing machine without the secondary baffle 23. In addition, the broken lines K 1 to K 4 in the ninth and tenth figures are based on the data when the washing amount is 1 kg, 3 kg, 5 kg, 8 kg. • 18- 200532068 (15) As can be clearly seen from Figures 9 and 10, the greater the height Η1 of the sub-baffle 23, or the greater the length 轴 2 in the axial direction, the greater the reduction in vibration. However, based on the vibration amplitude that occurs during dehydration operation, it is usually about 0.5 mm. The effect of reducing vibration is significant only when the amount of vibration reduction exceeds 0.5 mm. Next, among the 4 examples of the amount of laundry subjected to the experiment, at least two examples have a vibration reduction of 0.5 mm or more to form a great vibration reduction effect. The shape of the sub-baffle 23 is about the height of the formation. 30mm or more, the length in the axial direction is about 50mm or more. The height of the secondary baffle 23 will affect the effect of lifting the laundry 'and is related to the thickness of the laundry. Accordingly, since the thickness of the laundry is generally about 30 mm, the height of the sub-baffle is preferably 30 mm or more. The length of the auxiliary baffle 2 3 in the axial direction 'will affect the action of moving the laundry located at the end in the axial direction of the rotary tank 1 4 toward the center of the vibration system', and the length in the axial direction of the rotary shaft 1 4 and the end of the rotary tank 1 4 The distance from the center to the center of gravity of the vibration system is related. In the above-mentioned embodiment, since the length of the rotary groove 14 in the axial direction is 400 mm, and the distance from the end plate of the rotary groove to the center of gravity is 200 mm, the axial length of the sub baffle 23 with good vibration reduction effect can be obtained. Preferably, the length of the axis of the rotary groove I4 in the axial direction is more than one-eighth, and the distance from the end plate to the center of gravity is preferably more than one-fourth. However, the sub-baffle plate 23 must be arranged in a range from the end surface of the turning groove to the surface G on the inner surface of the groove wall portion. In addition, the sub-baffle plates provided on both end sides in the axial direction of the rotary groove may not be opposed to each other. Moreover, the sub-baffle only needs to be provided at the groove wall portion near the end plate of the rotary groove, and it is not necessary to make contact with the aforementioned end plate. -19- 200532068 (16) In the drum type washing machine where the rotation center axis of the rotary tank is inclined forward and upward, the laundry in the rotary tank is concentrated and concentrated downward, that is, the most coated part (rear) in the rotary tank, Therefore, it is better to set the auxiliary baffle on the groove wall portion of the rotary groove near the rear end plate. In the drum-type washing machine in which the center of gravity of the vibration system is shifted from the center of the axis of the rotary groove, it is preferable to form a pair of auxiliary dampers facing each other in the axial direction to have different axial lengths. In other words, when the center of gravity is located on one side of the axis _ center of the rotation axis, it is better to make the axial length of the sub-baffle disposed on one side of the groove wall portion in the axial direction longer than that of the sub-blade disposed on the other side. The baffle has a shorter axial length. However, each sub-baffle must be disposed within a range between the surface G passing through the center of gravity and the end plate. The sub baffle may be formed by stamping the groove wall portion or the end plate of the rotary groove. According to the above-mentioned structure, the sub-baffle plate can be integrated with the rotary groove, and can be easily assembled. The sub-baffle is not limited to a triangular cone shape, for example, it can also form a semi-φ cone shape. The present invention can also be applied to a drum type washing machine having a laundry inlet and outlet in the front.
