將形成有底圓筒形之旋轉滾筒2從開口之正面側朝成為底 邛之背面側且使旋轉轴20之方向或為從水平方向向下傾 斜’並藉設置於由懸吊器懸浮支撐之水槽3内。然後，開啟 設於洗衣機框體4之前部的開閉蓋5將洗衣物收货於旋轉滾 筒2，藉由以馬達6驅動旋轉滾筒2，而可進行洗衣步驟漂 洗步驟、及脫水步驟中之至少一個。開閉蓋5係由具嵌設有 可從外部透視洗衣物之透明玻璃板11之窗7的蓋本體8、與 201030206 使該蓋本體8之前面透明的蓋罩9構成。蓋本體8其蓋框8a係 以聚丙烯成形’且裏框8b係以耐藥品性更高之聚丙烯成 形。蓋框8a與裏框8b係將玻璃板11在其周邊部夾入且螺 固。蓋罩9係以透明之abs樹脂成形。 實施形態1之滾筒式洗衣機1，關閉後之開閉蓋5係具有 以與旋轉滾筒開口端2a相異的角度傾斜的關係。藉由開閉 蓋5具傾斜’而使從外部透視旋轉滾筒2内及將洗衣物取出 放入上不會產生特別不便之處。此處，藉由沿圓周方向以 斷面及斷面積大致相等且耐久性優異的環狀窗襯墊13而可 將開閉蓋5與水槽開口端3a之間密封。如習知般，蓋襯墊13 在側面視為錐形且斷面形狀、各斷面部的斷面積沿圓周方 向不同時，在受到於水槽開口端3a變得特別大的振動外力 時，作用在襯墊的負荷會於斷面積大的局部增大並集中， 而成為早期損傷、早期破損的原因。利用實施形態丨之構成 可防止如此事態的發生。 然後’藉由沿圓周方向斷面及斷面積大致均等且耐久 性優異的環狀窗襯塾13而將開閉蓋5與水槽開口端3a之間 密封。為了實現該構成，水槽開口端3a是被配置成以大致 平行傾斜與開閉蓋5相對向。而且，以前端與後端13b大 致平行之環狀窗襯墊13將該等開閉蓋5及水槽開口端％之 間密封。藉此，在洗衣物收容於旋轉滾筒2之後將開閉蓋5 關閉，藉此可適切地密閉。然後利用將旋轉滾筒2旋轉而於 進行洗衣步驟、漂洗步驟、及脫水步驟之至少一步驟時， 可阻止洗衣水、漂洗水及脫水之飛沫等漏出至外部。 201030206 又，使水槽開口端3a具有與開閉蓋5平行之傾斜，且藉 由前端13a與後端13b平行之環狀窗襯墊13而可將水槽開口 端3a與開閉蓋5之間密封。因此，可使窗襯墊13其斷面形狀 及各斷面部之斷面積沿圓周方向為均等者。 藉由以上之構成，將以相異於旋轉滾筒開口端以之角 度傾斜的開閉蓋5、與收容有旋轉滾筒2之水槽開口端允之 間密封，可適切地阻止洗衣水、漂洗水、脫水之飛沫等漏 出至外部。再者，利用環狀之窗概墊13大致平行開閉蓋$與 水槽開口端3a，而使窗襯墊13其斷面形狀及各斷面部之斷 面積沿圓周方向成為均等者。因此，在振動之水槽開口端 3a與停止之開閉蓋5之間，伴隨圓周方向之變位而反覆受到 壓迫及變形力時的負荷沿圓周方向均等化而不會於局部增 大且集中，而可在不會早期損傷且破損下實現長壽命化。 此處，前端13a係意味與開閉蓋5之壓接端及朝水槽開 口端3a之安裝端。又，後端13b係彈性地安裝於水槽開口端 3a外周之環狀凹部3b且構成座落於環狀凹部扑前面側之向 内凸緣3c的前面之安裝座部13bl。前端13a係將密封唇部 13a2形成大致直角斷面的二股狀，而該密封唇部13a2係密 嵌於壓接在開閉蓋5之蓋體8背面内周側的連續環狀面5 a之 壓接唇部13al及蓋本體8之窗7内周。蓋襯墊13全體係作為 以連繫部13c而連繫在安裝座部13bl之凸緣3c的寬度方向 大致中央位置與密封唇部13a2之二股狀連結部之間的形 態。 連繫部13c具有Μ字部13cl與折回部13c2。Μ字部13cl 201030206 利用使朝二股狀連結部之連結直徑相較安裝座部13bl之豎 立直徑為小，使從安裝座部13bl成為斷面Μ字狀且一邊的 腳部立起以使朝前部側成為稍微向外傾斜。折回部13c2折 回至在從Μ字部13cl之非豎立起侧另一邊的端部之前部 側’且在二股狀連結部以與開閉蓋5之軸線14平行地連繫於 密封唇部13a2。 在已關閉之開閉蓋5與水槽開口端3a之凸緣3c之間，蓋 襯墊13具有必要之密封壓。因此，蓋襯墊13藉由與水槽開 口端3a—起振動而作動作為彈性緩衝部。 而，開閉蓋5係以旋轉滾筒開口端2a與垂直面間的角度 傾斜，但是洗衣機框體4其前面4a係形成大致垂直者。藉 此，遏止了開閉蓋5之與旋轉滾筒開口端2&的角度差。再 者，也遏止了與洗衣機框體4之大致垂直之前面如的角度 差，且遏止了相對於垂直之洗衣機框體前面4a突出及凹陷 的量藉此’即使在以假想線14a顯示—部分般以前面對齊 的方式内建洗衣機框體4的情況τ，由於遏止了相對於前面 之傾斜所造成的突出及凹陷的量，所以家具及機器雙方之 外表可變佳。 如第7圖所示，水槽3具有於其水槽軀體部31之前部側 與旋轉滾筒開口仙大致平行且朝内徑側之水槽肩部32。 且具有自該水槽肩部32到與已闕之開職5大致平行的 位置使於_方向為相異高度之豎立壁33，並形成水槽開 口端33°於該登立㈣之豎立端部裝設有窗《13之後端 13b。藉此’在水槽軀體部31前部側設置與旋轉滾筒開口端 .201030206 2a^致平仃且朝内徑側之水槽肩部％，以覆蓋旋轉滾筒躺 體P側之必要前部區域，藉以謀求來自相對於旋轉之旋 轉滾筒2之外的安全。再者，於自水槽肩部32的圓周方向 藉由高度相異之董立壁33使水槽開口端^與開閉蓋5大致 平行，而可以具有M字部13c的形態等滿足支撐為了密封前 端13a與後端l3b平行之窗襯塾13與開閉蓋$所必須之備用 位置。然後’可以為必要最小限度之斷面積的窗概塾⑽ φ 確保充分之密封。 如第5圖所示’於水槽肩部32與豎立壁33所成之圓周方 向段差部34，利用螺栓而螺固於水槽肩部32上之複數輪穀 部32a等方式安裝大致收納於該段差範圍内大小之砝碼 15 >此之ϋ碼⑽為了接受水影的振動以分散衰減該振 動能量而使用。絲碼15係利用設於水槽3運動最大之前端部 的水槽肩部32與暨立壁33所成之圓周方向段差部从，而可 提高振動的抑制效率。又，缺碼15係可大致收納於段差部 ® 34内的大小。因此，砝碼15即使與水槽3—面一起使窗襯墊 13變形，一面振動的情況，也可迴避與窗襯墊Η干擾，且 不會使®襯塾13損傷。特別是，在段差部34之段差變大的 上部等，於使設於該處之砝碼15之大小對應段差變大時， 提高了相對於圓周方向之單位長度的重量，而提高了振動 之抑制效果。 >主水管30通過设有碎碼15之水槽肩部32的内側，且從 水槽3之外部避開安裝砝碼15之水槽肩部32的輪榖部323而 配置。藉此，透過覆蓋構件17之注水口 4〇如假想線所示般 9 201030206 喷射於旋轉㈣2㈣可有效敝水至洗補_是衣類。 又，水槽開口端3a與旋轉滾筒開口端之間隙係以具 有對應該等傾斜角度差之側面視寬度的環狀覆蓋構件口覆 蓋。亦即，覆蓋構件17藉由成為賴水槽.仙與旋轉 滾筒開口端2a之角度差的側面視錐形，而可不會超過或不 足地閉塞且覆蓋水槽開。端3&與旋轉滾筒開口❹的間 隙。因此’不會浪費覆蓋構件17讀料且可防止洗衣物爽 入水槽開口端3a與旋轉滾筒開口端2a之間。 而且，藉由於旋轉滚筒軀體部21之前部具有朝向内徑 側之旋轉滾筒肩部22，且形成直徑較旋轉滾筒㈣部叫、 之開口端，而可確保洗衣及漂洗時所必㈣水深。相對於 此，水槽料32於從豎立壁33之豐立端延伸於内徑侧的凸 緣3c内周，形成有以與旋轉滾筒開口端2槐持—定間隙而 相對向之内周壁15的-部分而構成雙重周壁的水槽開口端 h。藉此，迴避了旋轉滾筒開口端2a與水槽開口端％間之 門隙寬度在圓周方向不同且依場所而有大的間隙寬度。 覆蓋構件17之前端在水槽開口端3a之内周附近較水槽 開口端3a朝前部側突出—些，且將水槽開口仙之内周覆 蓋到旋轉滾㈣D端2a附近。再者，可作成使其覆蓋部的 内仏較旋轉滾筒開口端23之⑽小。覆蓋構件17藉由螺拾 18而螺固於形成在水槽肩部32之内側面的輪榖部32a。 第3圖、第4圖及第6圖係軀體板41之一部分的放大圖。 取出放入口 12係形成在形成除了洗衣機框體4前面如的上 下部分之範圍的金屬製軀體板41。此處，如習知般，在由 201030206 一片板成形軀體板41的情況下，使開閉蓋5相對大致垂直之 前面4 a於内側傾斜設置時，開閉蓋5封閉取出放入口丨2之封 閉區域及其周圍的環狀區域係成為從其下部朝上部自把體 板41構成之前面4a深入之凹陷部42，且上部區域變成深引 伸加工部。其結果，難以成形具滿足洗衣機框體4及開閉蓋 5之支撐所必需強度的厚度之軀體板41且成本變高。 在實施形態1 ’係使軀體板41分割形成為對應凹陷部们 之環狀的躯體板41b與其周邊框狀的躺體板4ia且一體化。 據此，軀體板41係藉由引伸度減半並可容易且低成本加工 之框狀的軀體板41a與環狀的軀體板41b之組合而獲得。 在實施形態1，係以點焊部43—體化，但是框狀的軀體 板41a與環狀的軀體板41b之一體化也可使用各種嫁接、柳 接、釘固、螺固等。為了該一體化，環狀的軀體板41b係於 前部側構成溝而形成朝後部側之環狀膨脹部4ibl以於内周 與蓋襯墊15壓接，並且具有在從該環狀膨脹部沿周邊平坦 延伸之後在上部側成為大曲面且在下部側臀曲豎立之外周 壁41b2。再者，使其在該外周壁41b2的前端形成向外之凸 緣部41b3，且框狀的軀體板41a於洗衣機框體4之前面4a形 成區域形成對應凹陷部42之外周部的側周壁4iai。然後， 在該側周壁41al之後端緣形成自後方緊靠於凸緣部41b3之 向内的凹陷周壁41a2。並將該等周壁41a3與凹陷周壁41a2 之重疊部在點焊部43所示之圓周方向複數個地方進行點 焊。 此處’在環狀的躺體板41b之左右其中一側從前部側緊 11 201030206 靠鉸鏈單元51，以螺栓螺固安裝，藉由該鉸鏈單元51而可 開閉地支撐開閉蓋5。於另一側將開閉蓋5之卡合片5a收納 到鎖固窗53a而鎖固，並緊靠可將開閉蓋5卡合於關閉狀態 之具蓋關閉檢測開關之蓋鎖固部53，以螺栓螺固。又，將 可解除鎖固之蓋開啟按鈕54從前部侧緊靠，再以螺栓固定。 再者’框狀的軀體板41a包含有形成洗衣機框體4之前 面4a的周壁41a3、以凹陷部42之寬度大小左右圓狀突出於 周壁41a3之上部的側周壁41al、及環狀之凹陷周壁4ia2。 使環狀的軀體板41b較厚，框狀的軀體板41a較薄，而組合 不同的板厚。因此，框狀的軀體板41a與環狀的軀體板41b 的重疊點焊構造及立體形狀協調一致且滿足必要的強度。 再者，使大面積之框狀的軀體板41a的板厚儘可能薄以使洗 衣機框體4輕量化且低成本化。 又，裝有軀體板41之鉸鏈單元51、蓋鎖固部53及蓋開 啟按鈕54之凹陷部42除了蓋開啟按鈕54，係以樹脂製之環 狀罩板44覆蓋予以外部裝飾。罩板44係以螺栓在圓周方向 複數個地方螺固於環狀的軀體板41b。藉此，於前部側卸下 罩板44時，會使裝備於軀體板41之鉸鏈單元51、蓋鎖固部 53及蓋開啟按鈕54露出，所以可對該等構件進行修補及交 換的維護。 再者，洗衣機框體4之前面4a係以框狀的軀體板41a、 閉塞於其上部及頂板57間之樹脂製頂點單元58、可安裝拆 卸地閉塞框狀的軀體板41 a之下部的樹脂製開閉板5 9形 成。頂點單元58係作為配置開始、停止之開關鍵61及各種 12 201030206 模式之設定操作部62、液晶顯示部63、顯示燈等之操作面。 罩板44及頂點單元58皆係樹脂成形品。而且，互相上 下鄰接一致的對向面44a、58a皆係對表面成直角連續地成 形，所以可無間隙地面對面。 據此，便成為在形成洗衣機框體4之前面4a上部之橫長 的樹脂面，以於其上將上部陷入的形態朝中央側向後側部 傾斜的樹脂面無間隙且以不同的顏色連續的特殊外觀。 如此之連續的罩板44及頂點單元58，其材質相異之金 屬製之與框狀的魏體板41 a之對向面44b、58b便與框狀的躺 體板41a的周壁41 a3及側周壁41 al鄰接一致。將該等周壁 41a3及側周壁41al彎曲加工所產生之具圓形的角隅部構成 形成間隙之對照部，而實現強調該等之表面存在、獨立性 的外觀構成。 罩板44及頂點单元58之緊接係將頂點單元％覆蓋於框 狀的軀體板41a之凹陷周壁41a2的前端而實現。又，該被覆 構造係從前部側將頂點單元58嵌固安裝於框狀的軀體板 41a的上部，以被覆於框狀的軀體板41a之周壁41a3的前端 而實現。因此，框狀的軀體板41a的拆卸在未優先進行頂點 單元58之拆卸時是無法進行的。對應於此，頂點單元％從 前部將上壁58a與下壁58b嵌入於框狀的軀體板41a之側周 壁41al與設於其外側之洗衣機框體4侧之固定壁64間。然 後，將向外形成於該等上壁58a與下壁58b之逆止突起彈性 卡合於形成在周壁41a3及固定壁64之卡合孔65而防止脫 落。而且，以大於該防止脫落力之外力，可簡單地將框狀 13 201030206 的軀體板41a拆卸。 藉由以上之構成’本發明之滾筒式洗衣機包含洗衣機 框體、設置於洗衣機框體内部之水槽、從開口之正面側朝 成為底部之背面側設置於水槽内以使旋轉轴方向自水平方 向成為向下傾斜之旋轉滾筒、設於洗衣機框體之前部的開 閉蓋、構成水槽之取出放入口的躯體板、及驅動旋轉滾筒 的馬達，且可進行洗衣步驟、漂洗步驟、脫水部驟之至少 一者’其特徵在於：軀體板包含構成洗衣機框體之前面且 具有開口部之框狀的軀體板、設於框狀的軀艎板與水槽之 開口端間之環狀的軀體板，並且框狀的軀體板與環狀的軀 體板形成一體化，且由框狀的軀體板與環狀的軀體板構成 之朝裏面方向之環狀的凹陷部係以環狀之罩板覆蓋而被外 部裝飾。藉此，開閉蓋即取出放入口相對洗衣機框體之前 面向後傾斜，不論洗衣機框體之前面的角度，成為配合旋 轉滚筒之傾斜姿勢，對洗衣物之取出放入、從外部之洗衣 物的透視可便利地易於使用者。又，洗衣機框體之前面的 角部由於包含垂直、後傾之選擇的自由度高，所以易於對 應各種用途及要求。同時，從軀體板形成的前面之凹陷部 係成為具有使自前面傾斜之取出放入口開口的底部之深引 伸形狀部，由於其開口側與底部側係以分割軀體板之框狀 的軀體板與環狀的軀體板分擔、形成而一體化，因此可迴 避深引伸加工並可容易且以低成本實現，並且只以罩板覆 蓋進行外部裝飾而可使外觀整齊。 並且，框狀的軀體板與環狀的軀艎板可更以其等形成 201030206 之凹陷部開口側之後端部向内凸緣部、與底部側之前端部 向外凸緣部之重合部間的熔接部而一體化。藉此，不會使 構造複雜且可獲得必要的強度。 並且’軀體板其板厚可更是具環狀的軀體板較框狀的 躺體板大之關係者。藉此，可只以面積大之框狀的軀體板 板厚變薄而使洗衣機倾輕量化且低成本化。 並且’環狀的躺體板係進一步於前部設有與開閉蓋之 Φ 開閉有關之開閉相關器具者，罩板係安裝以從凹陷部之前 部可裝卸者。藉此’而可以充分之強度安裝、安定且保持 開閉相關器具。又，因為可利用將罩板從前部卸下，以使 3又於則部之開閉相關器具露出於環狀的軀體板，所以可只 以自前部侧的作業而簡單且容易地進行該等開閉相關器具 之各種維護。 並且，更使軀體板為金屬製，環狀的罩板為樹脂製， 以於躺體板之上部將以樹脂製形成操作、顯示面之頂點單 φ 元設置並使對向者。藉此，可使環狀的罩板與頂點單元以 相同質感而統一。再者，在未有如金屬板之折弯的影響下 自由地選擇、設定有無間隙等對向、緊接條件，而可獲得 包含樹脂製2構件連續的外觀之最佳外觀者。 並且，洗衣機框體其前面更相對水平方向形成大致垂 直者。藉此，因為可使一致於如内建式使用的場合對象家 具之相同且垂直的前面’所以可使外觀整齊系統化。 並且，頂點單元更可為其前面係朝後部側傾斜設置 者。藉此，與對象家具之前面的整齊度不會太凌亂，而可 15 201030206 抑制對使用者之自然視線的傾斜，且易於視認並易於操作 者。 I：圖式簡單說明3 第1圖係有關實施形態1之滚筒式洗衣機的截面圖； 第2圖係前述滾筒式洗衣機之外觀的立體圖； 第3圖係前述滾筒式洗衣機之主要部分的立體圖； 第4圖係前述滚筒式洗衣機之主要部分的前視圖； 第5圖係前述滾筒式洗衣機之主要部分的前視圖； 第6圖係前述滾筒式洗衣機之主要部分的前視圖；及

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (Embodiment 1) Hereinafter, a drum type washing machine according to Embodiment 1 will be described with reference to FIGS. 1 to 7 . Further, the following description is not intended to limit the scope of the claims. As shown in Fig. 1 and Fig. 2, in the drum type washing machine 1 of the embodiment, the rotary drum 2 having the bottomed cylindrical shape is formed from the front side of the opening toward the back side of the bottom and the direction of the rotary shaft 20 Or it is inclined downward from the horizontal direction' and is placed in the water tank 3 supported by the suspension. Then, the opening and closing cover 5 provided at the front portion of the washing machine frame 4 is opened to receive the laundry to the rotating drum 2, and at least one of the washing step rinsing step and the dehydrating step can be performed by driving the rotating drum 2 with the motor 6. . The opening and closing cover 5 is composed of a cover body 8 having a window 7 in which a transparent glass plate 11 for seeing laundry from the outside is embedded, and a cover 9 having a front surface of the cover body 8 transparent to 201030206. The lid body 8 has a lid frame 8a formed of polypropylene and the inner frame 8b is formed of polypropylene having higher chemical resistance. The cover frame 8a and the inner frame 8b sandwich the glass plate 11 at its peripheral portion and are screwed. The cover 9 is formed of a transparent abs resin. In the drum type washing machine 1 of the first embodiment, the opening and closing cover 5 after closing has a relationship inclined at an angle different from the opening end 2a of the rotary drum. It is not particularly inconvenient to insert the inside of the rotary drum 2 from the outside and to take out the laundry by opening and closing the cover 5 with the inclination ′. Here, the opening and closing cover 5 and the water tank opening end 3a can be sealed by the annular window pad 13 having the same cross-sectional and sectional areas and excellent durability in the circumferential direction. As is conventionally known, the cover liner 13 is formed in a shape in which the side surface is tapered and the cross-sectional shape and the sectional area of each of the cross-sectional portions are different in the circumferential direction, and the external force is applied to the open end 3a of the water tank. The load of the liner will increase and concentrate locally in the large area, which will be the cause of early damage and early damage. The use of the configuration of the embodiment can prevent such a situation from occurring. Then, the opening and closing cover 5 and the water tank opening end 3a are sealed by the annular window lining 13 having a substantially uniform cross section and a large cross-sectional area in the circumferential direction and excellent durability. In order to achieve this configuration, the water tank opening end 3a is arranged to face the opening and closing cover 5 with a substantially parallel inclination. Further, the annular window spacer 13 which is substantially parallel to the front end and the rear end 13b seals between the opening and closing cover 5 and the open end of the water tank. Thereby, after the laundry is accommodated in the rotary drum 2, the opening and closing cover 5 is closed, whereby the sealing can be appropriately sealed. Then, by rotating the rotary drum 2 to perform at least one of the washing step, the rinsing step, and the dehydrating step, the washing water, the rinsing water, the dehydrated droplets, and the like can be prevented from leaking to the outside. 201030206 Further, the water tank opening end 3a has an inclination parallel to the opening and closing cover 5, and the water tank opening end 3a and the opening and closing cover 5 can be sealed by the annular window pad 13 which is parallel to the front end 13a and the rear end 13b. Therefore, the cross-sectional shape of the window spacer 13 and the sectional area of each cross-sectional portion can be made uniform in the circumferential direction. According to the above configuration, the opening and closing cover 5 which is inclined at an angle different from the opening end of the rotary drum and the opening end of the water tank in which the rotary drum 2 is accommodated are sealed, so that the washing water, the rinsing water, and the dehydration can be appropriately prevented. The droplets and the like leak out to the outside. Further, the annular window pad 13 is opened and closed substantially parallel to the opening end 3a of the water tank, and the cross-sectional shape of the window spacer 13 and the sectional area of each cross-sectional portion are equalized in the circumferential direction. Therefore, between the vibrating water tank opening end 3a and the stopped opening/closing cover 5, the load when the pressing force and the deformation force are repeatedly applied in the circumferential direction is equalized in the circumferential direction, and does not locally increase and concentrate. It can achieve long life without damage and damage at an early stage. Here, the front end 13a means the crimping end of the opening and closing cover 5 and the mounting end toward the sink opening end 3a. Further, the rear end 13b is elastically attached to the annular recessed portion 3b on the outer circumference of the open end 3a of the water tank, and constitutes a mounting seat portion 13b1 which is seated on the front side of the inward flange 3c on the front side of the annular recessed portion. The front end 13a forms a sealing shape of the sealing lip portion 13a2 in a substantially right-angled cross section, and the sealing lip portion 13a2 is closely fitted to the pressure of the continuous annular surface 5a which is crimped to the inner peripheral side of the back surface of the lid body 8 of the opening and closing cover 5. The lip 13a and the inner periphery of the window 7 of the cover body 8 are connected. The entire cover gasket 13 is connected to the joint portion 13c between the substantially central position in the width direction of the flange 3c of the mount portion 13b1 and the two-piece joint portion of the seal lip portion 13a2. The connecting portion 13c has a U-shaped portion 13cl and a folded-back portion 13c2. In the U-shaped portion 13cl 201030206, the connecting diameter of the connecting portion 13b1 is made smaller than the vertical diameter of the mounting seat portion 13b1, and the leg portion is formed in a U-shaped cross section from the mounting seat portion 13b1 so that the leg portion rises forward. The side of the part is slightly inclined outward. The folded-back portion 13c2 is folded back to the front portion side ' on the other side from the non-standing side of the U-shaped portion 13cl, and is connected to the seal lip portion 13a2 in parallel with the axis 14 of the opening and closing cover 5 in the two-strand joint portion. Between the closed opening and closing cover 5 and the flange 3c of the open end 3a of the water tank, the cover gasket 13 has the necessary sealing pressure. Therefore, the cover pad 13 operates as an elastic buffer portion by vibrating with the opening end 3a of the water tank. Further, the opening and closing cover 5 is inclined at an angle between the opening end 2a of the rotary drum and the vertical surface, but the front surface 4a of the washing machine casing 4 is formed substantially vertical. Thereby, the angular difference between the opening and closing cover 5 and the opening end 2& of the rotary drum is suppressed. Furthermore, the angular difference from the front surface of the washing machine casing 4 substantially perpendicularly is also suppressed, and the amount of protrusion and depression with respect to the vertical front surface 4a of the washing machine casing is suppressed, thereby being 'indicated even by the imaginary line 14a'. In the case where the washing machine casing 4 is built in the front alignment manner, since the amount of protrusion and depression caused by the inclination with respect to the front is suppressed, the appearance of both the furniture and the machine can be improved. As shown in Fig. 7, the water tank 3 has a water tank shoulder portion 32 which is substantially parallel to the rotary drum opening and has an inner diameter side on the front side of the water tank body portion 31. And having an upright wall 33 from the sink shoulder 32 to a position substantially parallel to the opened position 5, wherein the _ direction is a different height, and forming an open end 33 of the sink to be installed at the erect end of the standing (four) There is a window "13 rear end 13b. Thereby, the front side of the water tank body portion 31 is provided with the rotating drum opening end. 201030206 2a, and the water tank shoulder portion is made to face the inner diameter side to cover the necessary front portion of the rotating roller lying P side. It is desirable to be safe from outside the rotating drum 2 with respect to rotation. Further, in the circumferential direction of the shoulder portion 32 of the water tank, the opening end of the water tank is substantially parallel to the opening and closing cover 5 by the height of the wall 33, and the shape of the M-shaped portion 13c can be satisfied to support the front end 13a. The rear end l3b parallel window lining 13 and the alternate position necessary for opening and closing the cover $. Then the window profile (10) φ, which can be the minimum required cross-sectional area, ensures a sufficient seal. As shown in Fig. 5, the circumferential step portion 34 formed by the sink shoulder portion 32 and the upright wall 33 is attached to the plurality of valley portions 32a screwed to the sink shoulder portion 32 by bolts, and the like. The weight of the size 15 > This weight (10) is used in order to receive the vibration of the water shadow to disperse and attenuate the vibration energy. The yarn code 15 is formed by the circumferential step portion formed by the water tank shoulder portion 32 and the erecting wall 33 provided at the front end portion of the water tank 3 at the maximum movement, thereby improving the vibration suppression efficiency. Further, the missing code 15 can be roughly accommodated in the step portion 34. Therefore, even if the weight 15 is deformed together with the water tank 3 surface, the weight 15 can be prevented from interfering with the window spacer , and the lining 13 can be prevented from being damaged. In particular, when the step size of the step 15 is increased in the upper portion of the step portion 34, the weight of the unit length with respect to the circumferential direction is increased, and the vibration is increased. Inhibitory effect. > The main water pipe 30 is disposed inside the water tank shoulder 32 of the shredder 15 and is disposed away from the rim portion 323 of the sink shoulder 32 of the weight 15 from the outside of the water tank 3. Thereby, the water injection port 4 through the covering member 17 is as shown by an imaginary line. 9 201030206 Spraying on the rotation (four) 2 (four) can effectively drain the water to the washing _ is a clothing category. Further, the gap between the open end 3a of the water tank and the open end of the rotary drum is covered by an annular cover member having a side view width corresponding to the difference in the inclination angle. That is, the covering member 17 can be occluded without exceeding or insufficiently covering the sink opening by being a side view tapered shape which is a difference in angle between the sinking groove and the opening end 2a of the rotating drum. End 3& and the gap between the opening of the rotating drum. Therefore, the covering member 17 is not wasted and the laundry is prevented from entering between the open end 3a of the water tank and the open end 2a of the rotary drum. Further, since the front portion of the rotating drum body portion 21 has the rotating drum shoulder portion 22 facing the inner diameter side, and the opening end having a diameter smaller than that of the rotating drum (four) portion is formed, it is possible to ensure the (four) water depth at the time of washing and rinsing. On the other hand, the water tank material 32 is formed on the inner circumference of the flange 3c extending from the rich end of the upright wall 33 on the inner diameter side, and is formed to be opposed to the inner peripheral wall 15 by a predetermined gap with the open end 2 of the rotary drum. - Partially forming the open end h of the water tank of the double peripheral wall. Thereby, the gap width between the open end 2a of the rotary drum and the open end of the water tank is avoided in the circumferential direction and has a large gap width depending on the place. The front end of the covering member 17 protrudes toward the front side from the inner side of the water tank opening end 3a toward the front side of the water tank opening end 3a, and covers the inner circumference of the water tank opening to the vicinity of the rotating roller (four) D end 2a. Further, it is possible to make the inner circumference of the covering portion smaller than (10) of the opening end 23 of the rotary drum. The covering member 17 is screwed to the rim portion 32a formed on the inner side surface of the sink shoulder 32 by the screw pickup 18. 3, 4, and 6 are enlarged views of a portion of the body plate 41. The take-out port 12 is formed in a metal body plate 41 which forms a range of the upper and lower portions except for the front surface of the washing machine casing 4. Here, as is conventionally known, when the body panel 41 is formed of one plate from 201030206, when the opening and closing cover 5 is disposed obliquely on the inner side with respect to the substantially vertical front surface 4a, the opening and closing cover 5 closes the closure of the inlet port 2 The region and the surrounding annular region are recessed portions 42 which are formed from the lower portion toward the upper portion from the front surface 4a of the body plate 41, and the upper region becomes a deep drawing portion. As a result, it is difficult to form the body plate 41 having a thickness that satisfies the strength necessary for the support of the washing machine housing 4 and the opening and closing cover 5, and the cost is increased. In the first embodiment, the body plate 41 is divided into a ring-shaped body plate 41b corresponding to the recessed portions and integrated with the frame-shaped lying body plate 4ia. According to this, the body plate 41 is obtained by a combination of a frame-shaped body plate 41a and an annular body plate 41b which can be easily and inexpensively processed by halving the degree of extension. In the first embodiment, the spot welded portion 43 is formed, but various types of grafting, splicing, nailing, screwing, and the like can be used for the integration of the frame-shaped body plate 41a and the annular body plate 41b. For this integration, the annular body plate 41b is formed on the front side to form a groove to form an annular expansion portion 4ib1 on the rear side to be crimped to the cover liner 15 on the inner circumference, and has an annular expansion portion from the annular expansion portion. After extending flat along the periphery, the upper side becomes a large curved surface and the lower side is hip-curved to form an outer peripheral wall 41b2. Further, an outward flange portion 41b3 is formed at the front end of the outer peripheral wall 41b2, and the frame-shaped body plate 41a forms a side peripheral wall 4iai corresponding to the outer peripheral portion of the recessed portion 42 in the front surface 4a of the washing machine frame 4. . Then, the end edge of the side peripheral wall 41al is formed with a recessed peripheral wall 41a2 which abuts against the inward portion of the flange portion 41b3 from the rear. The overlapping portions of the peripheral wall 41a3 and the recessed peripheral wall 41a2 are spot-welded at a plurality of places in the circumferential direction indicated by the spot welded portion 43. Here, one side of the left and right side of the annular lying board 41b is fastened from the front side by the hinge unit 51 by the hinge unit 51, and the opening and closing cover 5 is openably and closably supported by the hinge unit 51. On the other side, the engaging piece 5a of the opening and closing cover 5 is received in the locking window 53a to be locked, and the cover locking portion 53 of the cover closing detecting switch that can close the opening and closing cover 5 in the closed state is abutted The bolts are bolted. Further, the unlockable cover open button 54 is abutted from the front side and fixed by bolts. Further, the frame-shaped body plate 41a includes a peripheral wall 41a3 that forms the front surface 4a of the washing machine housing 4, a side peripheral wall 41a1 that protrudes circularly from the upper portion of the peripheral wall 41a3 by the width of the recessed portion 42, and an annular recessed peripheral wall. 4ia2. The annular body plate 41b is made thicker, and the frame-shaped body plate 41a is thinner, and different plate thicknesses are combined. Therefore, the frame-shaped body plate 41a and the annular body plate 41b have an overlapping spot welding structure and a three-dimensional shape, and satisfy the necessary strength. Further, the thickness of the frame-shaped body plate 41a having a large area is made as thin as possible to reduce the weight and cost of the dishwasher casing 4. Further, the recessed portion 42 in which the hinge unit 51, the cover lock portion 53, and the cover opening button 54 of the body plate 41 are attached is covered with a resin-made annular cover plate 44 to be externally decorated. The cover plate 44 is screwed to the annular body plate 41b at a plurality of places in the circumferential direction by bolts. Thereby, when the cover panel 44 is removed at the front side, the hinge unit 51, the lid lock portion 53, and the lid open button 54 provided on the body panel 41 are exposed, so that repair and exchange of the members can be performed. . Further, the front surface 4a of the washing machine housing 4 is a frame-shaped body plate 41a, a resin apex unit 58 that is closed between the upper portion and the top plate 57, and a resin that can detachably close the lower portion of the frame-shaped body plate 41a. The opening and closing plate 59 is formed. The vertex unit 58 serves as an operation surface for the start/stop key 61 of the arrangement start and stop, and the setting operation unit 62, the liquid crystal display unit 63, and the display lamp of the various 12 201030206 modes. Both the cover plate 44 and the apex unit 58 are resin molded articles. Further, the opposing faces 44a, 58a which are adjacent to each other are formed continuously at right angles to the surface, so that the surface can be faced without a gap. As a result, the resin surface of the upper surface 4a of the front surface 4a of the washing machine frame 4 is formed so that the resin surface which is inclined toward the center side toward the rear side is formed without gaps and is continuous in different colors. Special appearance. The continuous cover plate 44 and the apex unit 58 are made of metal and the opposite faces 44b and 58b of the frame-shaped WEB plate 41a, and the peripheral wall 41a3 of the frame-shaped lying plate 41a and The side peripheral walls 41 a are adjacently aligned. The rounded corner portion formed by bending the peripheral wall 41a3 and the side peripheral wall 41al constitutes a contrast portion for forming a gap, and an appearance configuration that emphasizes the existence and independence of the surface is realized. Immediately after the cover plate 44 and the apex unit 58 cover the vertex unit % at the front end of the recessed peripheral wall 41a2 of the frame-shaped body plate 41a. In the cover structure, the vertex unit 58 is fitted and attached to the upper portion of the frame-shaped body plate 41a from the front side, and is covered by the front end of the peripheral wall 41a3 of the frame-shaped body plate 41a. Therefore, the detachment of the frame-shaped body plate 41a cannot be performed without preferentially disassembling the apex unit 58. In response to this, the apex unit % is fitted between the upper peripheral wall 41a of the frame-shaped body plate 41a and the fixed wall 64 on the side of the washing machine casing 4 provided outside the upper wall 58a and the lower wall 58b from the front. Then, the reverse projections formed outwardly of the upper wall 58a and the lower wall 58b are elastically engaged with the engagement holes 65 formed in the peripheral wall 41a3 and the fixed wall 64 to prevent detachment. Further, the body plate 41a of the frame shape 13 201030206 can be easily detached with a force larger than the force for preventing the detachment force. According to the above configuration, the drum type washing machine of the present invention includes a washing machine housing and a water tank provided inside the washing machine housing, and is disposed in the water tank from the front side of the opening toward the back side of the bottom portion so that the rotation axis direction becomes horizontal from the horizontal direction. a rotating drum that is inclined downward, an opening and closing cover that is provided at a front portion of the washing machine frame, a body plate that constitutes a sink inlet and outlet, and a motor that drives the rotating drum, and can perform a washing step, a rinsing step, and a dewatering step At least one of the following: the body plate includes a body plate having a frame shape having an opening portion in front of the washing machine frame body, and an annular body plate provided between the frame-shaped body plate and the open end of the water tank, and The frame-shaped body plate is integrated with the annular body plate, and the annular recessed portion formed by the frame-shaped body plate and the annular body plate in the inward direction is covered by the annular cover plate and is externally decoration. Therefore, the opening and closing cover, that is, the take-out and the entrance, are inclined rearward with respect to the washing machine frame, regardless of the angle of the front surface of the washing machine frame, and the tilting posture of the rotating drum is used, and the laundry is taken out and the laundry is taken from the outside. The perspective can be conveniently and easily used by the user. Further, since the corner portion on the front surface of the washing machine casing has a high degree of freedom in selection including vertical and backward tilting, it is easy to respond to various uses and requirements. At the same time, the front depressed portion formed from the body plate is a deep-drawn shape portion having a bottom portion for taking out the entrance opening from the front side, and the body plate of the frame-shaped body plate is divided by the opening side and the bottom side. It is shared and formed integrally with the annular body plate, so that deep drawing processing can be avoided and can be realized easily and at low cost, and the outer decoration can be made only by covering the outer cover with the cover plate. Further, the frame-shaped body plate and the annular body plate may be formed such that the recessed portion opening side of the 201030206 is formed between the rear end portion of the inward flange portion and the front end portion of the bottom side portion and the outer flange portion. The fusion joint is integrated. Thereby, the construction is not complicated and the necessary strength can be obtained. And the thickness of the body plate can be more closely related to the frame body of the body plate. As a result, the width of the body plate having a large area can be reduced, and the washing machine can be reduced in weight and cost. Further, the 'annular lying board system is further provided with an opening and closing device relating to the opening and closing of the opening and closing cover Φ in the front portion, and the cover plate is attached to the front portion of the recessed portion. By this, it is possible to install, stabilize, and keep the relevant instruments open and closed with sufficient strength. Further, since the cover plate can be removed from the front portion so that the opening and closing device for the third portion is exposed to the annular body plate, the opening and closing can be easily and easily performed only from the work on the front side. Various maintenance of related equipment. Further, the body plate is made of metal, and the ring-shaped cover plate is made of resin, and the upper portion of the lying body plate is formed by a resin forming operation, and the apex of the display surface is provided in a single φ element to be opposed. Thereby, the annular cover plate and the apex unit can be unified with the same texture. Further, it is possible to freely select and set the presence or absence of a gap or the like under the influence of the bending of the metal sheet, and to obtain an optimum appearance including the continuous appearance of the resin member. Further, the front surface of the washing machine casing is formed substantially perpendicular to the horizontal direction. Thereby, the appearance can be neatly integrated because the same and vertical front faces of the object furniture can be used in the same manner as in the built-in type. Also, the vertex unit can be tilted to the front side toward the rear side. Thereby, the uniformity with the front surface of the object furniture is not too messy, but 15 201030206 suppresses the inclination of the user's natural line of sight, and is easy to visualize and easy to operate.
