201111578 六、發明說明： 【明戶斤軒々貝j 發明領域 本發明係有關於一種具有旋轉軸水平或面向底部而朝 下傾斜之旋轉滾筒之滚筒式洗衣機。 發明背景 滾筒式洗衣機係使用具有循環幫浦之循環部，而使水 槽中貯存之洗淨水循環。舉例言之，特開平10-127978號公 報(專利文獻1)所揭露之滾筒式洗衣機係自循環部之噴嘴朝 旋轉滾筒中噴出洗淨水。喷嘴中形成有可自旋轉滾筒之前 面朝中心逐漸改變角度之多數噴出口。亦即，洗淨水係由 多數之喷出口喷出。藉此’即便衣物等洗濯物之量較多時， 亦可有效率地進行洗淨。 又，特開2008-073128號公報(專利文獻2)所揭露之滾筒 式洗衣機則包含具有2個幫浦吐出口之循環幫浦^ 2個幫浦 吐出口則依循環幫浦之葉輪之正逆旋轉方向而切換。2個幫 浦吐出口分別連接有循環軟管，而可切換對旋轉滾筒中之 洗净水之喷出方向。藉此，即可對應旋轉滾筒之正逆旋轉， 而改變清洗時及沖洗時之洗淨水之喷出方向。 然而，專利文獻1所揭露之滾筒式洗衣機係自多數 出D嘴出洗淨水。因此，洗淨水之使用量將 嘴 進行節水。 而不易 又，專利文獻2所揭露之滾筒式洗衣機係訝旋轉衷筒 201111578 落下之洗濯物澆灑洗淨水，而增加已浸滲洗淨水之洗濯物 之重量。重量已增加之洗濯物則在旋轉滾筒中重重落下。 藉此，而提昇洗淨之效率。此種清洗方式稱為禱洗。然而， 專利文獻2所揭露之滾筒式洗衣機在洗濯物量較多時，並未 充分增加洗濯物之重量，而無法形成檮洗之狀態。 【發明内容】 發明概要 本發明可於使水槽之洗淨水循環時，對旋轉滾筒中之 洗濯物有效率地供給洗淨水。藉此，本發明可提供一種洗 淨力較高之滚筒式洗衣機。 本發明之滾筒式洗衣機包含：機殼；水槽，設於機殼 内部，呈具有水槽開口之有底圓筒形；旋轉滾筒，設於水 槽内部，呈具有滚筒開口之有底圓筒形；馬達，裝設於水 槽之外底面，可藉水平或面向底部而朝下傾斜之旋轉軸使 旋轉滾筒旋轉。進而，本發明之滚筒式洗衣機亦包含：循 環通道，連通水槽之底側與水槽開口側，而可使水槽内部 之洗淨水自底側朝水槽開口側循環；及，複數喷出口，可 使藉循環通道而循環之洗淨水朝旋轉滾筒之内部喷出。 藉上述構造，循環之洗淨水即可自複數喷出口朝旋轉 滾筒之内部喷出。由於自複數喷出口喷出洗淨水，故可對 洗濯物有效率地供給洗淨水，並提昇滚筒式洗衣機之洗淨 力。 圖式簡單說明 第1圖係本發明第1實施例之滾筒式洗衣機之截面圖。 201111578 第2A圖係上述實施例之滾筒式洗衣機所裝載之循環幫 浦之截面圖。 第2B圖係上述實施例之滾筒式洗衣機所裝載之循環幫 浦之側面圖。

用以實施發明之最佳形態 (第1實施例） 201111578 第1圖係本發明第1實施例之滾筒式洗衣機之截面圖 第2 A圖係該實施例之浪筒式洗衣機所褒載之循環幫浦之截 面圖。第2B圖係§亥貫施例之滾筒式洗衣機所裝載之循产幫 浦之側面圖。 本實施例之滾筒式洗衣機1於機殼2内設有水槽3、供水 單元7、排水單元8及循環通道16。水槽3之内部設有旋轉穿 筒4。水槽3及旋轉滚筒4均呈有底圓筒形。旋轉滾筒4可藉 裝設於水槽3之外底面30上之馬達6而旋轉。馬達6可朝順時 針及逆時針之兩方向旋轉。亦即，馬達6可進行正逆向旋 轉。藉該等構造’則可進行清洗步驟、沖洗步驟及脫水步 驟。又，滾筒式洗衣機1視需要而設置乾燥單元9，則可進 行乾燥步驟。又，連通水槽3之底側與後述之水槽開口 13側 而設有循環通道16。循環通道16可使貯存於水槽3之洗淨水 自水槽3之底側朝水槽開口 13側循環。藉此，即可使洗劑快 速〉谷解於洗淨水中，或避免洗劑於洗淨水中溶解不均。 供水單元7與供水系統連接，開啓供水閥（未圖示），即 可朝水槽3進行供水。供水單元7之内部設有洗劑容置部（未 圖不）。由供水系統供入之水可溶解洗劑容置部之洗劑，並 ^成洗净水而流入水槽3。另，排水單元8則於清洗步驟結 束時及沖洗步驟結束時， 藉開啓排水閥19而朝機殼2外排出 /先'爭水。又，循環通道16則藉循環幫浦20而重複自水槽3之 底側吸入貯存於水槽3之洗淨水，並朝水槽開口 13側加以送 出，再予送回水槽3之動作。 7袞筒式洗衣機1於機殼2之前面上部設有操作面板21。 7 201111578 使用者藉操作面板21而進行作業開始之指示，則作業開始 之指示將送至控制單元22。控制單元22將使操作面板21之 顯示部（未圖示）顯示作業已開始，並關閉排水閥19,開啓供 水閥而開始供水。然後，控制單元22將進行清洗、沖洗、 脫水、乾燥等各作業。 機殼2之正面上形成有本體開口 2b，可藉門蓋5加以開 閉。旋轉滾筒4之正面上形成有滚筒開口 54。水槽3之正面 則形成有水槽開口 13。另，旋轉滚筒4及水槽3之正面係指 與其等個別之底部相對之面。洗濯物係經本體開口 2b、水 槽開口 13及滚筒開口 54而進出於旋轉滾筒4之内部。另，本 體開口 2b與水槽3之間裝設有環狀之密封材14。藉此，關閉 門蓋5後，可避免洗淨水自水槽3灑出。 馬達6具備正逆部分旋轉驅動模式與正逆連續旋轉驅 動模式，而可驅動旋轉滾筒4。正逆部分旋轉驅動模式係指 旋轉滚筒4朝正向及逆向重複90度以上180度以下之劇烈部 分旋轉之驅動模式。而，正逆連續旋轉驅動模式係指旋轉 滾筒4連續旋轉，且交互重複正向之旋轉與逆向之旋轉之驅 動模式。正逆連續旋轉驅動模式可使因旋轉滾筒4之旋轉而 上升之洗濯物重複因自重而落下，再因旋轉滾筒4之旋轉而 上升之動作。在進行清洗步驟或清洗步驟與沖洗步驟時， 係交互實施正逆部分旋轉驅動模式與正逆連續旋轉驅動模 式。 正逆部分旋轉驅動模式時，洗濯物將上升至90度以上 180度以下，然後因慣性力或自重而自旋轉滚筒4之内面脫 201111578 -» 落。洗濯物因吸含洗淨水而膨潤軟化且形成易滑動狀態， 故將因落下而散開。又，落下之機械力將作用於洗濯物， 而提昇滾筒式洗衣機1之洗淨功能。且’正逆部分旋轉驅動 模式時’將交互重複正向與逆向之部分旋轉’故洗濯物上 升之位置及落下之位置將交互變動。因此’可避免洗濯物 之糾結、扭結、發皺。 在此，正逆部分旋轉驅動模式下’不易發生複數洗濯 物彼此之上下位置之互換。又，位於旋轉滾筒4底部之洗濯 物不易移動，故容易發生清洗不均。因此’採用正逆連續 旋轉驅動模式’即可將位於旋轉滚筒4底部之洗濯物包括在 内而使洗濯物之上下位置互換。如此，藉正逆部分旋轉驅 動模式而避免洗濯物之糾結、扭結及發皺，並藉正逆連續 • 旋轉驅動模式而使洗濯物大幅度互換上下位置，即可平均 . 地進行洗淨。 循環幫浦20設於循環通道16中。且，循環幫浦2〇固定 於機殼2之底板2a上。循環幫浦2〇之下游側連接有循環通道 16之吐出側通道16b。如第2A及2B圖所示，循環幫浦20包 含可收置葉輪20a之樹脂製之幫浦機殼勘，以及可收置循 環馬達20c之馬達機殼20d。葉輪2加與循環馬達2〇c則藉馬 達軸20e而相連接。又’幫浦機殼勘與馬達機殼施係藉幫 浦機殼20b之開口側之轴承隔板麻而定位並一體化。另， 循環幫浦20係藉樹脂製之安裝座％而固定於底板以上。循 環馬達20c旋轉則可經馬達柏2〇e而使葉輪2〇a旋轉。藉葉輪 20a之旋轉，則可自循環幫浦吸入口斯朝循環幫浦吐出口 9 201111578 20g輸送洗淨水。 第3A圖係上述實施例之滚筒式洗衣機之水槽之要部立 體圖。第3B圖係上述實施例之滚筒式洗衣機之水槽之前面 壁之由内側觀察之平面圖。第4圖係上述實施例之滾筒式洗 衣機之循環通道之導水道附近之截面圖。如第3A及3B圖所 示，水槽3之前面壁3h之下半部形成有朝前方（第3A圖中右 上方）凸出並呈略Y字狀之凸出部3a。凸出部3a則藉螺釘55f 自水槽3之内側安裝有外形與凸出部3a大致相同之蓋部 55。又，如第4圖所示，蓋部55係經填料55a並藉凸出部3a 而安裝，且形成導水道55b。 第5A圖係上述實施例之滾筒式洗衣機之循環通道之吐 出口附近之截面圖。第5B圖係上述實施例之滾筒式洗衣機 之循環通道之其它吐出口附近之截面圖。凸出部3a之下端 連接有朝橫向延伸之連結部51之一端。連結部51之他端則 連接循環通道16之吐出側通道16b。又，蓋部55之左右上端 形成有缺口部55c。缺口部55c於蓋部55形成缺口，填料55a 之密封構造亦形成缺口。藉上述構造，而於因凸出部3a與 蓋部55而分支形成略Y字狀之導水道55b之左右上端部，形 成在與水槽3之前面壁3h之背面間具有朝周緣方向擴大之 開口之吐出口 55d。另，水槽3之前面壁3h之背面係指由内 側觀察水槽3時所見之面，即，與水槽3之内側相對之面。 循環幫浦20所輸送之洗淨水將通過循環通道16之吐出 側通道16b而自連結部51流入導水道55b。流入導水道55b之 洗淨水則流向水槽3之前面壁3 h之背面及與前面壁3 h之背 10 面相對之面之旋轉滾筒4之前面壁4b<表面之間並自吐出 口 55d被吐出。如第5圖所示’自導水道说經吐出口 55d而 ，土出之洗淨水將通過流道52而自環彳^^^^旋轉滾 筒4之内側喷出。另’吐出口 55d於旋轉滾筒4之旋轉方向上 設有複數個，而與環狀之噴出口 53相對。藉上述構造，可 朝旋轉滾筒4之_之廣大範圍内有致率地喷出洗淨水。 即，不拘洗濯物量之多寡，均可有致率地供給洗淨水。 在此，水槽3之前面壁3h自對應吐出口 55d之位置設有 傾斜面3ha及與傾斜面3ha連續之導引面％。自吐出口 5^朝 流道52吐出之洗淨水則自傾斜面3ha沿導引面56而流動。藉 此，洗淨水即可自喷出口 53通過滾筒開口 54，而如第5A圖 之箭號A所示，朝旋轉滚筒4之襄側噴出。洗淨水可喷至旋 轉滾筒4之裏側，故可更有效率地對洗濯物供給洗淨水。 進而，如第5B圖所示，設置傾斜角度與導引面56之傾 斜角度不同之導引面57，則可以不同之角度喷出洗淨水。 舉例言之，設由分支之導水道55b之正面所見左側之吐出口 55d(第3B圖中右側）所對應之導引面56之傾斜角度為a(參照 第5A圖）’且設由導水道55b之正面所見右側之吐出口 55d(第3B圖中左側）所對應之導引面57之傾斜角度為b(參照 第5B圖）。在此，導引面％及導引面57則形成符合傾斜角度 a>b之條件。 第6圖係顯示上述實施例之滾筒式洗衣機之洗淨水之 喷出狀態之說明圖°由滚筒式洗衣機1之正面所見左側之喷 出口 53所喷出之洗淨水（即第5A圖中朝箭號A所示方向噴出 201111578 之洗淨水）係如第6圖之喷灑形狀81所示朝上方喷出。而， 由滾筒式洗衣機1之正面所見右側之噴出口 53所喷出之洗 淨水（即第5B圖中朝箭號B所示方向喷出之洗淨水)則如第6 圖之喷灑形狀S2所示，朝較喷灑形狀以更偏下方之方向喷 出。即，各吐出口 55d所吐出之洗淨水將沿傾斜角度互異之 導引面56或導引面57而流動。然後，洗淨水將自喷出口 53 通過滾筒開口 54而朝旋轉滾筒4之内部噴出故將喷出喷出 角度不同之洗淨水。 又’導引面56或導引面57之傾斜角度將影響喷出後之 洗淨水之擴散狀態。傾斜角度較小時（即本實施例中傾斜角 度為b之導引面57) ’沿傾斜面3ha流入之洗淨水將因導引面 57而大幅改變角度。換言之，洗淨水將形成與導引面57對 撞之狀態。該狀態下，洗淨水將沿導引面57流動，並因對 撞而擴散。而，傾斜角度較大時（即本實施例中傾斜角度為 a之導引面56)，沿傾斜面3ha流入之洗淨水將仍沿導引面56 而流動，幾未經擴散而喷出。即，如第6圖所示’自傾斜角 度較小之右側之噴出口 53喷出之洗淨水之喷灑形狀S2 ’與 自傾斜角度較大之左側之喷出口 53喷出之洗淨水之喷麓形 狀S1相較，其具有擴大之形狀。即，左右之噴出口 53噴出 之洗淨水具有不同之擴散角度。舉例言之，傾斜角度在120 度程度以下時，洗淨水將大幅擴散而喷出，在130度程度以 上時’洗淨水將小幅擴散而呈膜狀喷出。如此，以不同噴 出角度噴出洗淨水，以及在不同擴散狀態下噴出洗淨水， 即可就洗濯物量較少時至較多時，進行個別適用之洗淨水 12 201111578 之喷出。 在此，剛開始進行洗淨後，洗濯物尚未吸含洗淨水， 而呈現體積較大之大份量狀態。舉例言之，第6圖所示之左 側之噴出口 53為洗濯物所封閉時，可由右側之喷出口 53朝 旋轉滚筒4喷出洗淨水。自右側之喷出口 53大幅擴散洗淨水 而加以喷出，故可使左側之喷出口 53附近之洗濯物快速浸 濕。吸含洗淨水後之洗濯物體積則減小，藉此而可解除左 側噴出口 53之封閉。 另，右側之喷出口 53所喷出之洗淨水之擴散較多，故 不易喷至旋轉滾筒4之裏側。然而，左側之喷出口 53所喷出 之洗淨水擴散較少，故可朝旋轉滾筒4之中心喷至裏側。藉 此，即可使旋轉滾筒4裏側之洗濯物快速浸濕。洗濯物快速 - 浸濕，即可使旋轉滾筒4中之洗濯物容易提早移動，而提昇 . 禱洗之效果。又，洗濯物快速浸濕，可使洗濯物體積提早 減小。藉此，將於洗濯物與洗濯物之間產生間隙，故可有 效率地對洗濯物進行洗淨水之喷出。即，可有效率地對洗 濯物進行洗淨水之供給。 在此，喷出口 53之喷出方向，即，相對於通過滾筒開 口 54中心之垂直線之洗淨水之喷出方向，可依喷出口 53之 形狀而有所不同。舉例言之，使左右之喷出口 53之喷出方 向與通過滾筒開口 54中心之垂直線所形成之角度為0度， 即，使喷出方向與上述垂直線成平行，即可使洗淨水容易 通過洗濯物與洗濯物之間隙而喷至旋轉滚筒4之裏側。又， 使右側之喷出口 53，即，洗淨水之擴散較多側之喷出口 53 13 201111578 之喷出方向與上述垂直線所形成之角度為35〜45度，且使左 側之喷出口 53，即洗淨水之擴散較少側之喷出口 53之喷出 方向與上述垂直線所形成之角度為50〜60度，即可抑制喷出 之洗淨水彼此之對撞。抑制洗淨水彼此之對撞，即可減少 供給洗淨水時之耗損。藉此，即可有效率地浸濕洗濯物， 並提昇滾筒式洗衣機1之洗淨效率。 如上所述，無論洗濯物之量多量少，均可有效率地供 給洗淨水，並有效率地浸濕洗濯物。有效率地浸濕洗濯物， 亦可獲致節水效果。又，吐出口 55d設於不致與旋轉滾筒4 中之洗濯物接觸之位置。因此，洗濯物將不致勾附於吐出 口 55d，而不致於進行清洗、沖洗、乾燥時造成阻礙。又， 洗濯物亦不致發生損傷及破損等情形。且，在正逆連續旋 轉驅動模式下進行洗濯物之上下互換，以及在正逆部分旋 轉驅動模式下進行洗濯物之左右互換，則可提高洗淨水之 喷出效果。另，本實施例中，雖就吐出口 55d設於左右2處 之情形加以說明，但吐出口 55d設有3處以上亦可進行相同 之實施。 (第2實施例） 第7A圖係本發明第2實施例之滚筒式洗衣機之循環通 道之吐出口附近之截面圖。第7B圖係該實施例之滾筒式洗 衣機之循環通道之其它吐出口附近之截面圖。與第1實施例 相同之構造則附以相同標號而加以說明。 如第7A及第7B圖所示，本實施例之滾筒式洗衣機1在 導引面58及導引面59與傾斜面3ha圓滑而彎曲相連之點 14 201111578 上’與第1實施例不同。導引面58與導引面59個別之彎曲半 徑不同。舉例言之’第7A圖所示之導引面58之彎曲半柄〇 大於第7B圖所示之導引面59之彎曲半徑d。即，彎曲半彳觅成 c > d之關係。洗淨水自傾斜面3ha沿導引面58流動時，洗淨 水將朝第7A圖之箭號C所示方向噴出。而，洗淨水自傾斜 面3ha沿導引面59流動時’洗淨水將朝第7B圖之箭號〇所示 方向喷出。由滾筒式洗衣機1之正面觀察，就左側之喷出口 53使用導引面58，而就右側之喷出口 53使用導引面59時， 則洗淨水將分別以第6圖所示之噴灑形狀S1及喷灑形狀幻 喷出。即，沿導引面58流動之洗淨水將如喷灑形狀S1而朝 上方喷出。而，沿導引面59流動之洗淨水則將如喷灑形狀 S2而朝下方喷出。如此，藉改變導引面之彎曲半徑，即可 改變洗淨水之喷出形狀。 又，導引面58或導引面约之彎曲半徑將影響噴出後之 洗淨水之擴散狀態《彎曲半徑較小時（即本實施例中彎曲半 徑為d之導引面约），沿傾斜面3ha流入之洗淨水將因導引面 59而大幅改變角度。換言之，洗淨水將形成與導引面59對 撞之狀態。該狀態下，洗淨水將沿導引面59而流動，並因 對撞而擴散。而，彎曲半徑較大時（即本實施例中彎曲半徑 為c之導引面5 8 )’沿傾斜面3 h a而流入之洗淨水將仍沿導引 面58而流動，幾未經擴散而噴出。即，如第6圖所示，自彎 曲半徑較小之右側喷出口 53喷出之洗淨水之噴灑形狀S2， 與自4曲半徑較大之左側噴出口53喷出之洗淨水之喷麗形 狀S1相杈，其具有擴大之形狀。如此，藉改變導引面之彎 15 201111578 曲半徑，即可獲致與第1實施例相同之作用效果。 (第3實施例） 第8圖係本發明第3實施例之滾请式洗衣機之循私'匕^ 之吐出口之截面圖。與第1實施例相同之構造則附以相同松 號加以說明。 如第8圖所示，本實施例之滾筒式洗衣機1中，導弓丨面 61具有與傾斜面3ha不同之傾斜角度。又，導引面61與傾斜 面3ha係經彎曲面60而速接。自吐出口 55d吐出之洗淨水則 流經彎曲面60，而可較第1實施例進行更圓滑之流動°因 此，噴出口 53所進行洗淨水之喷出更為安定。 又，洗淨水之導引面61之對撞程度係由彎曲面60之脅 曲半徑加以決定。即，調整彎曲面60之彎曲半徑，即牙調 整洗淨水之擴散程度。因此，調整導引面61之傾斜角度所 影響之洗淨水之喷出角度與彎曲面60之彎曲半徑所影響之 洗淨水之擴散程度，即町設定洗淨水之喷出形態。 (第4實施例） 第9圖係本發明第4實施例之滾筒式洗衣機之循環通道 之噴出口之截面圖。與第1〜3實施例相同之構造則附以相同 標號而加以說明。 如第9圖所示，本實施例之滾筒式洗衣機1中，導引面 62具有複數之傾斜角度之點，與第3實施例有所不同。導引 面62與傾斜面孙&經彎曲面60而連接之附近，具有傾斜角度 e。又’導引面62在前端部分之導引面前端部63附近，具有 傾斜角度f。在此，傾斜角度符合f>e之條件。上述構造可 16 201111578 於傾斜角度較小之部分發生洗淨水之對撞，而增大洗淨水 之擴散，並於傾斜角度較大之部分進行喷出角度較大之洗 淨水之喷出。另，傾斜角度e與傾斜角度f之差較大時，則 於導引面前端部63使洗淨水不沿行而脫離導引面62而喷 出〃果洗净水之喷出將不安定。此時，若進而形成 具有居中之傾斜角度之導引面62，則可避免洗淨水之脫離。 (第5實施例） 第10A圖係本發明第5實施例之滚筒式洗衣機之循環通 道之噴出口之截面圖。第1 〇 B圖係該實施例之滾筒式洗衣機 之循環通道之其它喷出口之截面圖。與第1〜4實施例相同之 構造，則附以相同標號而加以說明。 如第10A及10B圖所示，本實施例之滾筒式洗衣機丨在 - 導引面62之最前端部之形狀上與第4實施例不同。導引面62 - 之最前端部即前面壁3h之背面之端部。洗淨水之喷出角度 則受導引面62之最前端部之切線方向之影響。因此，洗淨 水之噴出角度可依導引面62之最前端部之形狀而加以設 疋。舉例&之，第10A圖中，導引面62之最前端部65係削邊 形狀者。可依該形狀而設定洗淨水之噴出角度，並抑制洗 '孤物之勾附，而避免洗濯物之損傷。又，第10Β圖中，導引 面62之最前端部66截面係略偏帶圓弧形之形狀者。該形狀 則可進而抑制洗濯物之勾附，並進而避免洗濯物之損傷。 (第6實施例） 第11圖係本發明第6實施例之滾筒式洗衣機之循環通 道之噴出口之截面圖。與第1〜4實施例相同之構造，則附以 17 U78 相同 之噴屮a

53所喷出之洗淨水之方向不同。在此，以第15A圖中吐出口 55da之情形說明開口角度。通過吐出口 55da而自喷出口 53 喷出之洗淨水將朝箭號E之方向喷出。該箭號e之方向即為 開口方向E。連結吐出口 55da之開口與旋轉滚筒4之旋轉中 心Q之線段Qd與開口方向E所成之角度j則為開口角度°因 此，第15A圖中吐出口 55d之開口角度為〇，第150圖中吐出 口 55db之開口角度則為k。詳而言之，通過吐出口 55d而自 喷出口 53喷出之洗淨水將朝箭號F之方向噴出。即’開口方 向為F。開口方向F與旋轉滚筒4之旋轉中心Q之方向致 故開口角度為0。又，通過吐出口 55db而自喷出口53喷出之 洗淨水將朝箭號G之方向喷出。即，開口方向為G開方 向G則與旋轉滾筒4之旋轉中心Q之方向形成角度k，故開口 角度為k。另，本實施例中，係於吐出口 55db之前端設置導 引部67，而朝箭號G之方向喷出洗淨水。即，開口方向及開 口角度可藉改變吐出口之前端形狀而加以設定。 在此，對應吐出口 55d之導引面57、對應吐出口 55鈕之 導引面56及對應吐出口 55db之導引面57分別以旋轉滚筒4 之旋轉中心Q為中心而構成環狀。因此，導弓丨面56及導引面 57之截面形狀相對於旋轉中心q而具有同〆之形狀。因此， 沿導引面56及導引面57流動之洗淨水在面甸旋轉滾筒4之 旋轉中心Q之方向上將大幅彎曲，且愈遠離面向旋轉滾筒4 之旋轉中心Q之方向，彎曲幅度愈小。故而，朝旋轉滾筒4 20 ·201 u 1578 之旋轉中心Q喷出而通過吐出口 55£1之洗淨水將呈大致對稱 之开〉狀且擴散較少地喷出。而，對旋轉滾筒4之旋轉中心Q 朝上方偏離角度j而噴出之通過吐出口 55da之洗淨水，以及 對方疋轉浪筒4之旋轉中心q朝上方偏離角度k而喷出之通過 吐出口

Field of the Invention The present invention relates to a drum type washing machine having a rotary drum having a rotating shaft horizontally or facing the bottom and inclined downward. BACKGROUND OF THE INVENTION A drum type washing machine uses a circulation portion having a circulation pump to circulate the washing water stored in the water tank. For example, the drum type washing machine disclosed in Japanese Laid-Open Patent Publication No. Hei No. 10-127978 (Patent Document 1) ejects washing water from a nozzle of a circulation portion toward a rotating drum. A plurality of ejection ports are formed in the nozzle which are gradually changed in angle toward the center before the self-rotating roller. That is, the washing water is sprayed from a plurality of discharge ports. Therefore, even when the amount of the laundry such as clothes is large, it can be efficiently washed. Further, the drum type washing machine disclosed in Japanese Laid-Open Patent Publication No. 2008-073128 (Patent Document 2) includes a circulation pump having two pump discharge ports, and two pump discharge ports are reversed by the impeller of the circulation pump. Switch by rotating direction. The two pump discharge ports are respectively connected with a circulation hose, and the discharge direction of the washing water in the rotary drum can be switched. Thereby, the forward and reverse rotation of the rotating drum can be changed, and the washing direction of the washing water during washing and washing can be changed. However, the drum type washing machine disclosed in Patent Document 1 is based on a lot of D nozzles. Therefore, the amount of washing water used to save water in the mouth. However, it is not easy, and the drum type washing machine disclosed in Patent Document 2 is a rotating cylinder. 201111578 The fallen washing water is poured into the washing water to increase the weight of the washing material which has been impregnated with the washing water. The washings whose weight has been increased are dropped in the rotating drum. Thereby, the efficiency of washing is improved. This type of cleaning is called prayer washing. However, the drum type washing machine disclosed in Patent Document 2 does not sufficiently increase the weight of the laundry when the amount of the laundry is large, and does not form a state of washing. SUMMARY OF THE INVENTION In the present invention, when the washing water of the water tank is circulated, the washing water can be efficiently supplied to the washing material in the rotary drum. Thereby, the present invention can provide a drum type washing machine having a high washing power. The drum type washing machine of the present invention comprises: a casing; a water tank disposed inside the casing and having a bottomed cylindrical shape having a water tank opening; and a rotating drum disposed inside the water tank and having a bottomed cylindrical shape having a drum opening; Installed on the bottom surface of the water tank, the rotating drum can be rotated by a rotating shaft that is inclined downward or horizontally toward the bottom. Further, the drum type washing machine of the present invention further includes a circulation passage that communicates with the bottom side of the water tank and the opening side of the water tank, and allows the washing water inside the water tank to circulate from the bottom side toward the opening side of the water tank; and, the plurality of discharge ports can The washing water circulated by the circulation passage is ejected toward the inside of the rotating drum. According to the above configuration, the circulating washing water can be ejected from the plurality of discharge ports toward the inside of the rotary drum. Since the washing water is sprayed from the plurality of discharge ports, the washing water can be efficiently supplied to the washings, and the washing power of the drum type washing machine can be improved.

Figure 16B is a partial cross-sectional view of line 16B-16B in Figure 16A. [Embodiment 3] The best mode for carrying out the invention (first embodiment) 201111578 Fig. 1 is a sectional view of a drum type washing machine according to a first embodiment of the present invention. Fig. 2A is a wave type washing machine of the embodiment. A cross-sectional view of the circular pump. Fig. 2B is a side view of the production pump loaded by the drum type washing machine of the embodiment. The drum type washing machine 1 of the present embodiment is provided with a water tank 3, a water supply unit 7, a drain unit 8, and a circulation passage 16 in the casing 2. The inside of the water tank 3 is provided with a rotary perforator 4. Both the water tank 3 and the rotary drum 4 have a bottomed cylindrical shape. The rotary drum 4 is rotatable by a motor 6 provided on the bottom surface 30 of the water tank 3. The motor 6 is rotatable in both the clockwise and counterclockwise directions. That is, the motor 6 can be rotated in a forward and reverse direction. With these configurations, a washing step, a rinsing step, and a dehydrating step can be performed. Further, the drum type washing machine 1 can be subjected to a drying step by providing the drying unit 9 as needed. Further, a circulation passage 16 is provided to communicate with the bottom side of the water tank 3 and the side of the water tank opening 13 to be described later. The circulation passage 16 allows the washing water stored in the water tank 3 to circulate from the bottom side of the water tank 3 toward the side of the water tank opening 13. Thereby, the lotion can be quickly dissolved in the washing water or the washing agent can be prevented from being unevenly dissolved in the washing water. The water supply unit 7 is connected to the water supply system, and the water supply valve (not shown) is opened to supply water to the water tank 3. A lotion containing portion (not shown) is provided inside the water supply unit 7. The water supplied from the water supply system dissolves the lotion of the lotion receiving portion and flows into the water tank 3 as washing water. Further, the drain unit 8 discharges/first rushes toward the outside of the casing 2 by opening the drain valve 19 at the end of the washing step and at the end of the rinsing step. Further, the circulation passage 16 is repeatedly sucked into the washing water stored in the water tank 3 from the bottom side of the water tank 3 by the circulation pump 20, and is sent to the side of the water tank opening 13 and sent back to the water tank 3. The 7-cylinder type washing machine 1 is provided with an operation panel 21 on the front surface of the casing 2. 7 201111578 When the user gives an instruction to start the operation by the operation panel 21, the instruction to start the operation is sent to the control unit 22. The control unit 22 causes the display unit (not shown) of the operation panel 21 to display that the work has started, closes the drain valve 19, and opens the water supply valve to start the water supply. Then, the control unit 22 performs various operations such as washing, rinsing, dehydrating, and drying. A body opening 2b is formed on the front surface of the casing 2, and can be opened and closed by the door cover 5. A drum opening 54 is formed on the front surface of the rotary drum 4. A sink opening 13 is formed in the front surface of the water tank 3. Further, the front faces of the rotary drum 4 and the water tank 3 refer to the faces opposite to the respective bottom portions thereof. The washing material enters the inside of the rotary drum 4 via the body opening 2b, the water tank opening 13 and the drum opening 54. Further, an annular seal member 14 is disposed between the body opening 2b and the water tub 3. Thereby, after the door cover 5 is closed, the washing water can be prevented from being spilled from the water tank 3. The motor 6 is provided with a forward-reverse partial rotation drive mode and a forward-reverse continuous rotation drive mode, and the rotary drum 4 can be driven. The forward/reverse partial rotation driving mode refers to a driving mode in which the rotary drum 4 is repeatedly rotated in the forward direction and the reverse direction by a severe partial rotation of 90 degrees or more and 180 degrees or less. However, the forward-reverse continuous rotation driving mode refers to a driving mode in which the rotary drum 4 continuously rotates and alternately repeats the forward rotation and the reverse rotation. In the forward/reverse continuous rotation drive mode, the washings that have been raised by the rotation of the rotary drum 4 are repeatedly dropped by their own weight, and the movement of the rotary drum 4 is increased. When performing the washing step or the washing step and the rinsing step, the forward and reverse partial rotational driving modes and the forward and reverse continuous rotational driving modes are alternately implemented. In the forward and reverse partial rotation drive mode, the washing material will rise to 90 degrees or more and 180 degrees or less, and then take off from the inner surface of the rotating drum 4 due to inertia force or self-weight. 201111578 -» The washing material is swollen and softened by the absorption of the washing water and forms a slippery state, so that it will spread out due to falling. Further, the mechanical force of the falling will act on the washing and lift the washing function of the drum type washing machine 1. Further, when the 'reverse and reverse partial rotation driving mode' will alternately rotate the forward and reverse portions of the interaction, the position where the laundry rises and the position where it falls will alternately change. Therefore, the tangling, kinking, and wrinkling of the washings can be avoided. Here, in the forward/reverse partial rotation driving mode, the interchange of the plurality of washing materials with each other above and below is less likely to occur. Further, since the laundry located at the bottom of the rotary drum 4 is not easily moved, cleaning unevenness is likely to occur. Therefore, the laundry located at the bottom of the rotary drum 4 can be included by the use of the forward and reverse continuous rotary drive mode to interchange the upper and lower positions of the laundry. In this way, the positive and negative partial rotation driving mode avoids the entanglement, kinking, and wrinkling of the washing material, and the washing and washing is performed in a continuous/rotary driving mode to substantially exchange the upper and lower positions of the washing material, and the washing can be performed on average. The circulation pump 20 is disposed in the circulation passage 16. Further, the circulation pump 2 is fixed to the bottom plate 2a of the casing 2. The downstream side of the circulation pump 2 is connected to the discharge side passage 16b of the circulation passage 16. As shown in Figs. 2A and 2B, the circulation pump 20 includes a resin casing made of resin capable of accommodating the impeller 20a, and a motor casing 20d which can accommodate the circulation motor 20c. The impeller 2 is applied to the circulation motor 2〇c by the motor shaft 20e. In addition, the pump casing and the motor casing are positioned and integrated by the bearing partition of the opening side of the casing 20b. In addition, the circulation pump 20 is fixed to the base plate by the resin mount %. When the circulating motor 20c rotates, the impeller 2〇a can be rotated by the motor cymbal 2〇e. By the rotation of the impeller 20a, the self-circulating pump suction port can be sent to the circulation pump discharge port 9 201111578 20g to deliver the washing water. Fig. 3A is a perspective view of the main part of the water tank of the drum type washing machine of the above embodiment. Fig. 3B is a plan view of the front wall of the water tank of the drum type washing machine of the above embodiment as viewed from the inside. Fig. 4 is a cross-sectional view showing the vicinity of the water conduit of the circulation passage of the drum type washing machine of the above embodiment. As shown in Figs. 3A and 3B, the lower half of the front wall 3h of the water tank 3 is formed with a projection 3a which is convex toward the front (upper right in Fig. 3A) and has a substantially Y-shape. The projection 3a is attached to the inside of the water tank 3 by a screw 55f to have a cover portion 55 having an outer shape substantially the same as that of the projection portion 3a. Further, as shown in Fig. 4, the lid portion 55 is attached to the filler portion 55a via the filler 55a, and a water conduit 55b is formed. Fig. 5A is a cross-sectional view showing the vicinity of the discharge port of the circulation passage of the drum type washing machine of the above embodiment. Fig. 5B is a cross-sectional view showing the vicinity of another discharge port of the circulation passage of the drum type washing machine of the above embodiment. One end of the joint portion 51 extending in the lateral direction is connected to the lower end of the projection 3a. The other end of the joint portion 51 is connected to the discharge side passage 16b of the circulation passage 16. Further, the left and right upper ends of the lid portion 55 are formed with a notch portion 55c. The notch portion 55c is notched in the lid portion 55, and the sealing structure of the filler 55a is also formed as a notch. According to the above configuration, the left and right upper end portions of the water channel 55b which is slightly Y-shaped by the projection portion 3a and the lid portion 55 are formed to have an opening which is enlarged toward the circumferential direction between the back surface of the front wall 3h of the water tank 3. Spit out 55d. Further, the back surface of the front wall 3h of the water tank 3 refers to the surface which is seen when the water tank 3 is viewed from the inner side, that is, the surface which faces the inner side of the water tank 3. The washing water sent from the circulation pump 20 passes through the discharge side passage 16b of the circulation passage 16 and flows into the water conduit 55b from the joint portion 51. The washing water flowing into the water conduit 55b flows to the back surface of the front wall 3h of the water tank 3 and the front surface wall 4b of the rotary drum 4 opposite to the back surface 10 of the front wall 3h. <The surface is spit out from the spit port 55d. As shown in Fig. 5, the self-guided water passage is discharged through the discharge port 55d, and the washed water from the soil is discharged from the inside of the rotary drum 4 through the flow passage 52. Further, the discharge port 55d is provided in plural in the rotation direction of the rotary drum 4, and is opposed to the annular discharge port 53. With the above configuration, the washing water can be sprayed in a large amount toward the wide range of the rotary drum 4. That is, the amount of the uncleaned material can be supplied to the washing water in a probable manner. Here, the front wall 3h of the water tank 3 is provided with an inclined surface 3ha and a guide surface % continuous with the inclined surface 3ha from the position corresponding to the discharge port 55d. The self-venting outlet 5^ the washing water discharged into the flow path 52 flows along the guiding surface 56 from the inclined surface 3ha. Thereby, the washing water can be ejected toward the side of the rotary drum 4 from the discharge port 53 through the drum opening 54, as indicated by the arrow A in Fig. 5A. The washing water can be sprayed to the inside of the rotary drum 4, so that the washing water can be supplied to the laundry more efficiently. Further, as shown in Fig. 5B, by providing the guide surface 57 having an inclination angle different from that of the guide surface 56, the washing water can be ejected at different angles. For example, it is assumed that the inclination angle of the guide surface 56 corresponding to the discharge port 55d (the right side in FIG. 3B) on the left side of the branch water channel 55b is a (see FIG. 5A) and is provided by the water conduit. The inclination angle of the guide surface 57 corresponding to the discharge port 55d on the right side (the left side in FIG. 3B) on the front side of the 55b is b (refer to FIG. 5B). Here, the guide surface % and the guide surface 57 form a condition that conforms to the inclination angle a > b. Fig. 6 is an explanatory view showing the state of discharge of the washing water of the drum type washing machine of the above-described embodiment. The washing water sprayed from the discharge port 53 on the left side of the front side of the drum type washing machine 1 (i.e., Fig. 5A) The washing water of 201111578 is ejected in the direction indicated by the arrow A. It is ejected upward as indicated by the spray shape 81 of Fig. 6. The washing water sprayed from the discharge port 53 on the right side of the front side of the drum type washing machine 1 (i.e., the washing water sprayed in the direction indicated by the arrow B in Fig. 5B) is sprayed as shown in Fig. 6. As shown by the shape S2, it is ejected in a direction that is more downward than the spray shape. In other words, the washing water discharged from each of the discharge ports 55d flows along the guide surface 56 or the guide surface 57 which are different in inclination angle. Then, the washing water is ejected from the discharge port 53 through the drum opening 54 toward the inside of the rotary drum 4, so that the washing water having a different discharge angle is ejected. Further, the inclination angle of the guide surface 56 or the guide surface 57 affects the diffusion state of the washing water after the ejection. When the inclination angle is small (i.e., the guide surface 57 having the inclination angle b in the embodiment), the washing water flowing in along the inclined surface 3ha will largely change the angle due to the guide surface 57. In other words, the washing water will form a state of colliding with the guide surface 57. In this state, the washing water will flow along the guide surface 57 and spread due to the collision. On the other hand, when the inclination angle is large (that is, the guide surface 56 having the inclination angle a in this embodiment), the washing water flowing in along the inclined surface 3ha will still flow along the guide surface 56, and will be ejected without diffusion. . That is, as shown in Fig. 6, the spray shape S2' of the washing water sprayed from the discharge port 53 on the right side having a small inclination angle and the washing water sprayed from the discharge port 53 on the left side having a large inclination angle The sneeze shape S1 has an enlarged shape as compared with the sneeze shape S1. That is, the washing water sprayed from the left and right discharge ports 53 has different diffusion angles. For example, when the inclination angle is less than 120 degrees, the washing water is largely diffused and ejected, and when the inclination is more than 130 degrees, the washing water is slightly diffused to be ejected in a film form. In this manner, when the washing water is sprayed at different discharge angles and the washing water is sprayed in different diffusion states, the spray of the individual applicable washing water 12 201111578 can be performed when the amount of the washing material is small to a large amount. Here, immediately after the washing is started, the washings have not yet absorbed the washing water, and the bulky state is large. For example, when the discharge port 53 on the left side shown in Fig. 6 is closed by the washing, the washing water can be ejected toward the rotary drum 4 from the discharge port 53 on the right side. Since the washing port 53 on the right side is largely diffused and washed, the washing material in the vicinity of the discharge port 53 on the left side can be quickly wetted. The volume of the washing liquid after the washing with the washing water is reduced, whereby the closing of the left side discharge port 53 can be released. Further, since the washing water sprayed from the discharge port 53 on the right side has a large amount of diffusion, it is not easily sprayed to the inside of the rotary drum 4. However, since the washing water sprayed from the discharge port 53 on the left side is less diffused, it can be sprayed toward the inner side toward the center of the rotary drum 4. Thereby, the washing material on the inner side of the rotary drum 4 can be quickly wetted. The washing material is fast - soaked, so that the washings in the rotating drum 4 can be easily moved early, and the effect of the washing is improved. Moreover, the rapid wetting of the washings can reduce the volume of the washings earlier. Thereby, a gap is formed between the washing material and the washing material, so that the washing water can be efficiently ejected. That is, the supply of the washing water can be efficiently supplied to the laundry. Here, the discharge direction of the discharge port 53, i.e., the discharge direction of the washing water with respect to the vertical line passing through the center of the drum opening 54, may vary depending on the shape of the discharge port 53. For example, the angle between the discharge direction of the left and right discharge ports 53 and the vertical line passing through the center of the drum opening 54 is 0 degrees, that is, the discharge direction is parallel to the vertical line, so that the washing water can be made. It is easy to spray to the inside of the rotary drum 4 by the gap between the washing and the washing. Further, the discharge port 53 on the right side, that is, the discharge direction of the discharge port 53 13 201111578 on the side where the washing water is diffused more, is formed at an angle of 35 to 45 degrees with respect to the vertical line, and the discharge port 53 on the left side is made. That is, the angle between the discharge direction of the discharge port 53 on the side where the diffusion of the washing water is less and the vertical line is 50 to 60 degrees, and the collision of the sprayed washing water can be suppressed. By suppressing the collision of the washing water, the wear and tear of the washing water can be reduced. Thereby, the washing material can be effectively wetted, and the washing efficiency of the drum type washing machine 1 can be improved. As described above, regardless of the amount of the laundry, the amount of the washing material can be efficiently supplied to the washing water, and the washing material can be efficiently wetted. Efficiently soaking the washings can also achieve water-saving effects. Further, the discharge port 55d is provided at a position where it does not come into contact with the laundry in the rotary drum 4. Therefore, the laundry will not be attached to the spout 55d, and will not be hindered by washing, rinsing, and drying. In addition, the washings are not damaged or damaged. Further, in the forward/reverse continuous rotation driving mode, the washings are exchanged up and down, and in the forward and reverse partial rotation driving modes, the left and right sides of the washings are exchanged, whereby the washing effect of the washing water can be improved. In the present embodiment, the case where the discharge port 55d is provided at two places on the left and right sides will be described, but the discharge port 55d may be provided in three or more places. (Second Embodiment) Fig. 7A is a cross-sectional view showing the vicinity of a discharge port of a circulation passage of a drum type washing machine in accordance with a second embodiment of the present invention. Fig. 7B is a cross-sectional view showing the vicinity of the other discharge port of the circulation passage of the drum type washing machine of the embodiment. The same configurations as those of the first embodiment will be described with the same reference numerals. As shown in Figs. 7A and 7B, the drum type washing machine 1 of the present embodiment differs from the first embodiment in that the guide surface 58 and the guide surface 59 are smoothly and curvedly connected to the inclined surface 3ha. The guiding surface 58 and the guiding surface 59 have different bending halves. For example, the curved half-handle 导引 of the guide surface 58 shown in Fig. 7A is larger than the bending radius d of the guide surface 59 shown in Fig. 7B. That is, the curve is bent into a relationship of c > d. When the washing water flows along the guide surface 58 from the inclined surface 3ha, the washing water is ejected in the direction indicated by the arrow C of Fig. 7A. On the other hand, when the washing water flows from the inclined surface 3ha along the guide surface 59, the washing water is ejected toward the direction indicated by the arrow 〇 in the Fig. 7B. As seen from the front of the drum type washing machine 1, the guide surface 58 is used for the discharge port 53 on the left side, and when the guide surface 59 is used for the discharge port 53 on the right side, the washing water is sprayed in the shape shown in Fig. 6, respectively. S1 and spray shape squirting. That is, the washing water flowing along the guiding surface 58 will be ejected upward as in the spray shape S1. On the other hand, the washing water flowing along the guide surface 59 is ejected downward as in the spray shape S2. Thus, by changing the bending radius of the guiding surface, the ejection shape of the washing water can be changed. Moreover, the bending radius of the guiding surface 58 or the guiding surface will affect the diffusion state of the washing water after the ejection. "When the bending radius is small (that is, the guiding surface having the bending radius d in this embodiment is about), the inclination is along the inclination The washing water flowing into the surface 3ha will largely change the angle due to the guiding surface 59. In other words, the washing water will form a state of colliding with the guide surface 59. In this state, the washing water flows along the guide surface 59 and spreads due to the collision. However, when the bending radius is large (that is, the guiding surface 58 of the bending radius c in this embodiment), the washing water flowing in along the inclined surface 3 ha will still flow along the guiding surface 58, and is not diffused. And spout. That is, as shown in Fig. 6, the spray shape S2 of the washing water sprayed from the right discharge port 53 having a small bending radius and the spray water sprayed from the left discharge port 53 having a large radius of the four curves are sprayed. The shape S1 is opposite, and has an enlarged shape. Thus, by changing the radius of the curved surface of the guide surface 15 201111578, the same effects as those of the first embodiment can be obtained. (Third Embodiment) Fig. 8 is a cross-sectional view showing the spouting outlet of the portable washing machine of the third embodiment of the present invention. The same configurations as those of the first embodiment will be described with the same loose numbers. As shown in Fig. 8, in the drum type washing machine 1 of the present embodiment, the guide bow face 61 has an inclination angle different from that of the inclined face 3ha. Further, the guide surface 61 and the inclined surface 3ha are fastened via the curved surface 60. The washing water spouted from the discharge port 55d flows through the curved surface 60, and the smoother flow can be performed than in the first embodiment. Therefore, the discharge of the washing water by the discharge port 53 is more stable. Further, the degree of collision of the guide surface 61 of the washing water is determined by the radius of curvature of the curved surface 60. That is, the bending radius of the curved surface 60 is adjusted, that is, the degree of diffusion of the tooth-washing water. Therefore, the degree of diffusion of the washing water affected by the angle of the washing water affected by the inclination angle of the guide surface 61 and the bending radius of the curved surface 60, that is, the discharge form of the washing water is set. (Fourth Embodiment) Fig. 9 is a cross-sectional view showing a discharge port of a circulation passage of a drum type washing machine in accordance with a fourth embodiment of the present invention. The same configurations as those of the first to third embodiments are denoted by the same reference numerals. As shown in Fig. 9, in the drum type washing machine 1 of the present embodiment, the guide surface 62 has a plurality of inclination angles, which is different from the third embodiment. The guide surface 62 has an inclination angle e in the vicinity of the inclined face and the curved surface 60. Further, the guide surface 62 has an inclination angle f in the vicinity of the leading end portion 63 of the leading end portion. Here, the inclination angle satisfies the condition of f>e. In the above structure, the collision of the washing water occurs in the portion where the inclination angle is small, and the diffusion of the washing water is increased, and the washing of the washing water having a large discharge angle is performed in the portion where the inclination angle is large. When the difference between the inclination angle e and the inclination angle f is large, the washing water is discharged from the guide surface 62 at the leading end portion 63 of the guide surface, and the discharge of the washing water is unsettled. . At this time, if the guide surface 62 having the centering inclination angle is further formed, the detachment of the washing water can be avoided. (Fifth Embodiment) Fig. 10A is a cross-sectional view showing a discharge port of a circulation passage of a drum type washing machine in accordance with a fifth embodiment of the present invention. Fig. 1B is a cross-sectional view showing another discharge port of the circulation passage of the drum type washing machine of the embodiment. The same configurations as those of the first to fourth embodiments will be described with the same reference numerals. As shown in Figs. 10A and 10B, the drum type washing machine of the present embodiment is different from the fourth embodiment in the shape of the foremost end portion of the guide surface 62. The leading end portion of the guide surface 62 - is the end portion of the back surface of the front wall 3h. The discharge angle of the washing water is affected by the tangential direction of the most front end portion of the guide surface 62. Therefore, the discharge angle of the washing water can be set in accordance with the shape of the most front end portion of the guide surface 62. For example, in Fig. 10A, the foremost end portion 65 of the guide surface 62 is a shape of a beveled edge. The discharge angle of the washing water can be set according to the shape, and the attachment of the washing object can be suppressed, and the damage of the washing material can be avoided. Further, in the tenth diagram, the front end portion 66 of the guide surface 62 has a slightly curved cross section. This shape can in turn inhibit the attachment of the wash and further avoid damage to the wash. (Embodiment 6) FIG. 11 is a cross-sectional view showing a discharge port of a circulation passage of a drum type washing machine in accordance with a sixth embodiment of the present invention. The same structure as in the first to fourth embodiments is attached with the same squirt a of 17 U78. To illustrate. The drum type washing machine 1 of the embodiment is in washing water and yang <Diffusion, slightly forming a guide bow 丨" 'The angle of the mouth, the stability of the discharge and the damage of the washing ‘ α 53. Specifically, the discharge port 53 is provided with a plurality of inclination angles, a degree of inclination, a stability of the discharge, and a damage of the washing material, and a variation of the thickness of the resin to be ejected, and the guide bow of the eleventh figure is provided. The kneading surface 64, the road 6 〇, and the stunned two 6 guiding surfaces 6 are known to have a curved surface having a plurality of bending radii, and the blade is smeared and smoothly connected. According to the above configuration, it is possible to form the & the curved surface 60b and the curved surface 6〇c in the surface of the washed female and the damage of the washing material, and the resin forming the guide surface 64. Further, in the case of the variation in the thickness of the water sprayed, [...], (in the seventh embodiment), the diffusion and discharge angle of the discharge are set. 12th - "Spit discharge D" The seventh embodiment of the present invention For example, the cycle of the drum type washing machine is attached with a wearing map near the same handle u. The same configuration as that of the first embodiment will be described. In the first to sixth embodiments, the discharge port 53 has been described as a structure in which the washing water discharged from the discharge port 55d is discharged to the rotary drum 4 through the drum. The washing machine 1 of the present embodiment has a self-discharging outlet Md which is directly ejected toward the rotary drum 4, and specifically, s', as shown in Fig. 2, a discharge port 55d is provided at a position where the water tank 3 is diametrically opposed to the drum. In other words, the configuration of the discharge port 55d and the discharge port 53 is shared. The above configuration does not require the provision of the guide faces 56 and the like constituting the discharge port 53. That is, the guide surface 56 or the like which may cause the laundry to be attached may not be provided. Therefore, it is not obstructed when washing, rinsing, and drying. Also, the washings are not damaged or damaged. Further, the discharge port 55d may be provided on a member constituting a closing member such as the lid portion 55. (Eighth Embodiment) 18 201111578 Fig. 13 is a plan view showing the front wall of the water tank of the drum type washing machine in the eighth embodiment of the present invention as seen from the inside. Fig. 14A is a cross-sectional view showing the vicinity of the discharge port of the circulation passage of the drum type washing machine of the embodiment. Fig. 14B is a cross-sectional view showing the vicinity of another discharge port of the circulation passage of the drum type washing machine of the embodiment. Fig. 15A is a plan view of the front wall of the front wall of the drum type washing machine of the embodiment as viewed from the inside. Fig. 15B is a plan view showing the front wall of the other sink of the drum type washing machine of the embodiment as viewed from the inside. Fig. 16A is a cross-sectional view showing the vicinity of another discharge port of the circulation passage of the drum type washing machine of the embodiment. Figure 16B is a partial cross-sectional view of line 16B-16B in Figure 16A. The same configurations as those of the first embodiment will be described with the same reference numerals. As shown in Fig. 13, the opening width D1 of the opening direction of the opening of one of the discharge ports 55d is different from the opening width D2 of the size of the circumferential direction of the opening of the other outlet 55da. The width of the washing water discharged from each of the discharge port 55d and the discharge port 55da is different depending on the opening width. By this means, the discharge form of the washing water can be appropriately set, and the washing water can be appropriately supplied to the washing material regardless of the amount of the washing material. Moreover, if the washing water is appropriately supplied, the washing effect can be improved. Further, as shown in Figs. 14A and 14B, the opening distance D3 of the opening of one of the discharge ports 55d in the direction perpendicular to the circumferential direction is perpendicular to the circumferential direction of the opening of the other discharge port 55da. When the opening distance D4 is different, the discharge flow rate of the washing water can be made different. According to the above configuration, the washing form of the washing water can be appropriately set, and the washing water can be appropriately supplied to the washing material regardless of the amount of the washing material. In addition, proper cleaning of the washing water can improve the washing effect. Further, as shown in Figs. 15A and 15B, the opening angles of the rotation centers Q of the pair of right and left discharge ports of the rotary drum 4 are different, and the direction of the washing water sprayed from the left and right discharge ports 53 can be made different. Here, the opening angle will be described with reference to the discharge port 55da in Fig. 15A. The washing water sprayed from the discharge port 53 through the discharge port 55da is ejected in the direction of the arrow E. The direction of the arrow e is the opening direction E. The angle j formed by the line segment Qd connecting the opening of the discharge port 55da and the rotation center Q of the rotary drum 4 and the opening direction E is the opening angle. Therefore, the opening angle of the discharge port 55d in Fig. 15A is 〇, Fig. 150 The opening angle of the spout 55db is k. More specifically, the washing water sprayed from the discharge port 53 through the discharge port 55d is ejected in the direction of the arrow F. That is, the opening direction is F. The direction of the opening F and the direction of the center of rotation Q of the rotary drum 4 cause the opening angle to be zero. Further, the washing water sprayed from the discharge port 53 through the discharge port 55db is ejected in the direction of the arrow G. That is, the direction of the opening G in the G direction forms an angle k with the direction of the center of rotation Q of the rotary drum 4, so the opening angle is k. Further, in the present embodiment, the guide portion 67 is provided at the front end of the discharge port 55db, and the washing water is sprayed in the direction of the arrow G. That is, the opening direction and the opening angle can be set by changing the shape of the front end of the discharge port. Here, the guide surface 57 corresponding to the discharge port 55d, the guide surface 56 corresponding to the discharge port 55 button, and the guide surface 57 of the corresponding discharge port 55db are formed in a ring shape around the rotation center Q of the rotary drum 4, respectively. Therefore, the cross-sectional shape of the guide bow face 56 and the guide face 57 has the shape of the same with respect to the center of rotation q. Therefore, the washing water flowing along the guiding surface 56 and the guiding surface 57 will be greatly bent in the direction of the rotation center Q of the rotary drum 4, and the farther away from the direction of the rotation center Q facing the rotary drum 4, the bending width The smaller. Therefore, the washing water which is ejected toward the center of rotation Q of the rotary drum 4 20 · 201 u 1578 and passes through the discharge port 55 £1 is discharged in a substantially symmetrical shape and less diffused. The washing water passing through the discharge port 55da which is discharged from the rotation center Q of the rotary drum 4 by the angle j upward, and the rotation center q of the opponent's rocker 4 are displaced upward by the angle k, and are discharged through the discharge port. 55db of washing water will spread and spread out. Further, as shown in Figs. 16A and 16B, inside the water conduit 5, a rib 68 is provided in the vicinity of the discharge port 55d in a direction in which the flow of the washing water can be hindered. The rib 68 is formed by partially protruding one of the lid portions 55. The rib 6 8 has a size of about 50% of the cross-sectional area of the flow path which can block the water passage 5 5 b. Here, when the washing water flowing through the water conduit 55b through the circulation passage 16 is discharged from the discharge outlet 55d It has a velocity component in the same direction as the long direction of the water conduit 55b. The washing water is discharged from the discharge port 55d and guided by the speed component. The surface 56 is ejected toward the direction of the rotary drum 4 in the longitudinal direction of the guide channel 55b. Here, by providing the ribs 68, the washing water flowing through the water conduit 55b can collide with the ribs 68. Thereby, the speed component of the long direction of the washing water can be reduced, and the washing water can be ejected from the discharge outlet 55d and the guide surface 56 in the direction facing the rotary drum 4. That is, the washing water can be ejected in a direction in which the discharge port 5 is in the direction of the direction of the guide surface 56. Further, as shown in Fig. 15A or 15B, the rib 68 may be provided inside the water discharge passage 55b near the discharge port 55da or the discharge port 55db.
