201111584 例如’在第6圖（b )的構造中係有以下技術之提案： 可藉由將鉸鏈機構3 4 0配置在無圖示的前框補強板的左側 或右側’使其他的開關蓋3 3 0或外裝體等左右對稱，即可 謀求零件共有的技術。 [先前技術文獻] [專利文獻] [專利文獻1]日本特開2009-95530號公報 [專利文獻2]日本特開2007-195859號公報 [專利文獻3]日本特開2〇〇4_1〇5268號公報 【發明內容】 [發明所欲解決的課題] 根據上述第6圖（a )的構造，利用簡單的構造即可使 開關門3 3 0大幅度打開，並且，只要改變鉸鏈機構3 4 〇的配 置’即可使左右開啓的對應更加容易。但是，根據此構造 的話’開關門3 3 0必須朝筐體3 1 0的前面大幅度突出來設置 ’所以在設置性或設計面仍存在著重大課題。特別是，門 體3 3 2必須強力支持著具有重量的透明窗3 3 1，所以其厚度 d也會變大，從筐體3 1 0的前面大幅度突出，使得設計面受 到極大的限制。 再者，若根據第6圖（b )的構造，可將門體3 3 2收納 在筐體3 1 〇內，所以在設置性或設計面雖可獲得改善，但 因爲必須採用具備圓弧狀之弧狀臂部341的鉸鏈機構340， 201111584 所以，鉸鏈機構3 4 0的大型化或強度即成 在這種構造中，爲了對應左右開啓’就4 的左右設置大型化之鉸鏈機構3 4〇的配置 體更加大型化。 因此，本發明的目的即爲：提供一種 ，即可對應開關門的左右開啓，並且設置 的洗衣機。 [用以解決課題之手段] 爲了達成上述目的，本發明的洗衣機 具有旋轉軸幾乎呈水平的旋轉槽，且在筐 衣物取出投入至該旋轉槽的衣物投入口的 其特徵爲：具備：開關門，該開關門係以 設置，在衣物投入口的單側具有鉸鏈機構 具有鎖定機構部；以及包圍該開關門之周 件，鉸鏈機構部係使該旋轉軸位在比筐體 的位置，階差減輕構件除了具備使開關門 之前面部連續的傾斜面，又在對應於鉸鏈 構部的兩側，具備凹狀的缺口部》 [發明效果] 根據本發明，除了可使朝向前方突出 的前面融合’減輕該突出感，並且將手放 ’即可以將該開關門大幅度開啓。 爲問題。並且， :、須在筐體3 1 0內 空間，使裝置全 利用簡單的構造 性或設計性優異 係針對在筐體內 體的前面具有將 滾筒式洗衣機， 可開啓的方式來 部，在另一單側 圍的階差減輕構 的前面更爲前方 之前面部與筐體 機構部與鎖定機 的開關門與筐體 在開關門的一側 -8- 201111584 【實施方式】 兹參照第1圖至第5圖’具體說明本發明之洗衣機如下 。在說明中，同一部位或箭頭等皆以相同符號顯示，故省 略重複說明。 首先’參照第1圖來說明本實施例之洗衣機的槪略構 造。在此’第1圖係爲本發明之洗衣機的槪略構造圖。 在第1圖中’以符號1來統括表示的洗衣機係爲：在箱 型的筐體10內，配置了呈橫姿勢之無圖示的圓筒形洗衣槽 的滾筒式洗衣機。在本實施例中，筐體10係由：構成箱型 之筐體10之框架的基座筐體11 ;包覆該筐體11之前面的前 殼體12;以及包覆筐體11之上面的頂板13所構成。前殻體 1 2係由：由鋼板沖壓加工所形成的前面板1 4 :以及被設置 在前面板構件1 4之上部，由樹脂材料所形成的操作面板構 件1 5所形成，這些構件係藉由無圖示的螺絲等，被裝設在 基座筐體1 1。 在前面板1 4係形成了圓形開口的衣物投入口 2 0，圓形 的開關門40係藉由鉸鏈機構1〇〇與開閉鎖定機構150，以可 開閉的方式來裝設，使可覆蓋該衣物投入口 2 0。意即’開 關門4 0對筐體1 0而言，係利用被設置在左側端部的鉸鏈機 構1 0 0，而可以向左開啓關閉之方式來設置，又利用設於 右側端部的開閉鎖定機構1 5 0來鎖定衣物投入口 2 0的閉鎖 狀態。 在此，鉸鏈機構1 0 0係由：設於筐體1 0側的鉸鏈軸部 1 1 0 ;以及設於開關門4 0側’支持著鉸鏈軸部n 0的鉸鏈保 -9 - 201111584 持部1 3 0 (第5圖）所構成。又，同樣的，開閉鎖定機構 1 50係由：設於開關門40側的桿機構部1 60 ;以及設於筐體 1〇側’使桿機構部160呈鎖定狀態的桿嵌合受部ι8〇所構成 〇 此外’開關門4 0的框架係由：由樹脂材料所形成之環 狀的前框41 ;以包覆該前框41之背面的方式來設置，由樹 脂材料所形成的環狀後框4 2 ;以及被支持在該後框4 2與前 框4 1之間，由耐熱玻璃所形成的透明窗4 3所構成。透明窗 43係以嵌入至衣物投入口 20內般，朝內側大幅度伸出所形 成。 如第1圖之左下衍伸框內所示，在本實施例中，在衣 物投入口 20的周圍係形成了環狀的凹部21，該環狀的凹部 21係比前面板構件I4之其他面更爲凹陷形成，在該凹部21 的左右對向的位置係設有：鉸鏈機構100的鉸鏈軸部110、 以及開閉鎖定機構1 5 0的桿嵌合受部1 8 0。設於凹部2 1的鉸 鏈軸部110係具備：朝前方伸出，支持著一對的旋轉軸部 111之一對突起臂部112，設於該一對的突起臂部112之前 端的一對旋轉軸部1 1 1，係以可旋轉的方式被支持在設於 開關門40之端部的鉸鏈保持部130(第5圖）。另一方面， 設於凹部2 1的桿嵌合受部1 80係具備嵌合穴部1 8 1，利用將 構成桿機構部160的可動桿161***嵌合到該嵌合穴部181 ，可使開關門40呈鎖定狀態。 有關本實施例之洗衣機1的較大特徵之一爲：在衣物 投入口 20的周圍設有環狀的階差減輕構件60，該環狀的階 -10- 201111584 差減輕構件6 0係在左右對向的位置形成了一對缺口部6 1。 意即，本實施例所採用的鉸鏈機構1〇〇係藉由突起臂 部1 1 2，使一對的旋轉軸部1 1 1從前面板構件1 4朝向前方突 出，藉由如此，可使被裝設在該一對旋轉軸部1 1 1的開關 門40可大幅度開啓。並且，利用突起臂部112來支持一對 旋轉軸部1 1 1係爲簡單的構造，所以可獲得強度，並且也 可使支持旋轉軸部111的鉸鏈保持部13〇也爲簡單的構造。 但是，爲了讓開關門40大幅度開啓，例如打開1 80度，就 必須使一對的旋轉軸部1 1 1朝前方大幅度突出。也就是說 ，必須使開關門40從前面板構件1 4朝向前方大幅度伸出。 因此，從前面板構件1 4大幅度伸出之開關門4〇的設計性就 會變差，或者是會發生物品碰撞到伸出的開關門4 0之端部 的問題。特別是，此種的滾筒式洗衣機大都是嵌入到系統 廚房的流理台內，所以也會產生突出形狀的開關門40與整 齊的系統蔚房不協調的問題。 因此，本發明者爲了解決該課題’即採用了以下構造 :在突出形狀的開關門4〇之周圍設置了環狀的階差減輕構 件6 0，利用階差減輕構件6 0使由平面的前面板構件1 4、以 及從該前面板構件1 4突出的開關門4 〇所產生的階差和緩連 續。藉由如此，即如圖1之右下衍伸框內所示’可使突出 形狀的開關門4 0呈和緩***的形狀’所以可減輕上述課題 。此外，利用環狀的階差減輕構件6 0來包圍開關門4 0的周 圍’可使開關門4 0在視覺上變大’讓使用者對衣物投入口 20的大小具有印象’可提昇使用者的使用感。又’藉由在 -11 - 201111584 該環狀的階差減輕構件60施以多樣的色彩，可提高其設計 性。 但是，一旦利用環狀的階差減輕構件60來包圍突出形 狀的開關門40之周圍，就會發生開關門40無法大幅度開啓 的問題。因此，本發明者就藉由在與較鏈軸部110鄰接的 階差減輕構件60形成缺口部61，以確保開關門40的動作範 圍。 再者，本發明者考量到開關門40的手動開關，藉由在 與開閉鎖定機構150鄰接的階差減輕構件60形成缺口部61 ，即可確保利用手動來開啓開關門40的使用者的手所*** 的動作範圍。 又，藉由左右對稱形成了分別確保開關門40之動作範 圍、以及***使用者之手的動作範圍的缺口部61，即可呈 現出設計性優良的形態。 再者，有關本實施例之洗衣機1的另一較大特徵爲： 藉由採用具有左右對稱形成之一對缺口部61的階差減輕構 件60，即可使開關門40輕易地對應左開或右開。 在本實施例中，在凹部2 1的對向位置係裝設了鉸鏈軸 部1 10與桿嵌合受部180，所以，利用像是把前面板構件14 的沖壓成型的模具置換爲鉸鏈軸部110與桿嵌合受部180之 對應部分等既存的簡單構造，即可改變鉸鏈軸部110與桿 嵌合受部180的左右位置。然後，利用使開關門40左右反 轉來安裝，即可使開關門40對應左右開啓。 茲參照第1圖、以及第2圖到第5圖，進一步詳細說明 -12- 201111584 本實施例的洗衣機如下。在此，圖2係爲洗衣機的外觀圖 ，（a )圖爲開關門關閉狀態的立體圖，（b )圖爲開關門 開啓狀態的立體圖，（c )圖爲將開關門朝右開啓之狀態 的立體圖。第3圖爲階差減輕構件的外觀圖，（a )圖爲平 面圖，（b)圖爲正面圖，（c)圖爲右側面圖，（d)圖 爲背面圖，（e )圖爲從背面所看到的立體圖。第4圖爲鉸 鏈軸部之旁邊的部份剖面圖。第5圖爲顯示開關門之動作 狀態的部分剖面圖，（a )圖爲閉鎖狀態，（b )圖爲開啓 狀態。 首先，在第2圖中係說明了洗衣機1的外觀圖。如（a )圖所示，根據本實施例，突出的開關門40的周圍係利用 以傾斜面連續的階差減輕構件6 0，與平坦的前面板構件1 4 相連，所以，突出的開關門40爲和緩***形狀，融合於平 坦的前面板構件1 4，可使使用者不易注意到該突出形狀。 並且，階差減輕構件60的左右部份係因爲缺口部6 1的 形成，透過該右側的缺口部6 1，將單手揷入，握住形成於 開關門4〇的握把1 62 ’拉向身體側，即可解除開閉鎖定機 構1 50的鎖定狀態，將開關門40打開。又，被打開的開關 門40係可藉由左側的缺口部6 1來確保其動作範圍，所以如 (b )圖所示，可將開關門4 0大幅度打開。 又，在本實施例中，於前面板構件1 4的沖壓加工中， 只要利用將模具的鉸鏈軸部1 1 〇與鉸鏈保持部1 30的部份置 換來成型’使開關門40反轉交換，即可如（C )圖所示般 ，變成右開之開關門4 0的構造。 -13- 201111584 接下來，在第1圖與第2圖中，於本實施例中所採用的 開閉鎖定機構1 50係使用習知技術所形成。在此’因與本 發明的特徵沒有深切的關係，所以只說明其槪略構造。 開閉鎖定機構150係由：設於開關門40的桿機構部160 ;以及設於凹部21的桿嵌合受部1 80所構成。桿機構部160 係由：被設置在對應於缺口部61之開關門4〇的前部的握把 162 ;使前端部從開關門40的內面突出設置的可動桿161 ; 以及無圖示的轉換機構所構成，該轉換機構係將握把162 的動作轉換爲可動桿1 6 1之內外周方向的動作。露出的可 動桿161的前端部係呈鍵形，藉由將握把162拉向身體側’ 該動作利用轉換機構，可使鍵形的可動桿1 6 1的前端轉換 成開放的方向。 另一方面，桿嵌合受部1 80係具備嵌合穴部1 8 1。該嵌 合穴部1 8 1的入口係呈硏鉢狀，利用關閉開關門4〇的動作 ，將呈鎖定狀態的可動桿1 6 1的前端部揷入’使其一端動 作爲開放狀態，更進一步***前端部的話，就會因爲設於 開閉鎖定機構1 50之無圖示的彈簧作用’可動桿1 61回復到 原先的鎖定狀態。 如此一來，在本實施例中，打開開關門4〇時’經由缺 口部6〗將手指***到握把1 62，將該握把1 62拉向身體側即 可打開，而在關閉開關門4〇時，不須將手握住握把162 ’ 只要直接把開關門40關上，可動桿1 6 1之鍵形的前端部就 會與嵌合穴部1 8 1嵌合’呈鎖定的狀態。 接下來，第3圖係爲階差減輕構件60的外觀圖。本實 -14- 201111584 施例的階差減輕構件60係具備：由樹脂材料所形成的環狀 外觀形狀’其前面係呈從外側朝向內側豎立之緩緩彎曲的 傾斜面。另一方面’背面側的形狀係爲：內側的緣部63係 具備朝向後方伸出的形狀。這是爲了可使該內側的緣部63 嵌入至形成在衣物投入口 20之周圍的凹部21。又，在背面 側係左右對稱形成了複數的旋鎖部62，藉由如此，即可旋 鎖固定在前面板構件1 4。 接下來，參照第4圖來說明鉸鏈軸部110之周圍的構造 。首先，在第4圖中，本實施例的洗衣機1係在筐體10的內 部具備洗衣槽2，在筐體10的前面設有將衣物投入至在該 洗衣槽2的衣物投入口 20。洗衣槽2係由：被筐體10所支撐 的外槽3 ;以及利用無示的驅動馬達，以可旋轉的方式被 裝設在該外槽3內的內槽4所構成。驅動馬達的旋轉軸係以 呈略水平的方式被裝設在外槽3的背面側。內槽4係爲圓筒 狀形成，以其軸心呈橫向姿勢般地被裝設在上述旋轉軸。 內槽4與外槽3的前面係呈圓形開口，開關門40的透明窗43 係經由被設置在筐體1〇之前面的衣物投入口 20 ’***到該 開口部5。外槽4的開口部5與衣物投入口 2 0 ’係利用被裝 設在其周圍的柔軟性構件之波紋管6 ’以不會漏水的方式 連結在一起。 如上所述，形成於前面板構件14的衣物投入口 20的周 圍，係形成了環狀的凹部2〗’該環狀的凹部2 1係比其他的 前面板構件14之前面更低一階。階差減輕構件60係以：內 側的緣部6 3與凹部2 1相接’外側與凹部2 1的外側之面相接 -15- 201111584 的方式，藉由上述的旋鎖部62’被裝設在前面板構件14。 另一方面，鉸鏈軸部11〇係由：藉由無圖示的螺絲， 被裝設在凹部21的基座構件113;被設置在該基座構件113 的一對突起臂部112;以及被設置在~對臂部U2之前端部 的旋轉軸部1 1 1所構成。一對的旋轉軸部1 1 1係以朝向外側 般，被裝設在突出的突起臂部Π2。並藉由無圖示的軸承 部來裝設開關門40，該無圖示的旋軸承部，係以可旋轉之 方式支撐著朝向該外側來裝設的旋轉軸部1 1 1。 接下來，參照第5圖來進一步說明開關門40的構造、 以及利用鉸鏈機構1〇〇之開關門40的開放動作。 首先，在第5圖中係如上述般，開關門40係由：構成 該開關門40之前部的前框41 ;構成開關門40之背面部的後 框42 ;以及被保持在前框4 1與後框42之間的透明窗43所構 成。在前框41與後框42的內側係具備無圖示的安裝肋部， 使透明窗43被保持在前框4 1，又利用旋鎖住後框42，將透 明窗43確實保持在前框41與後框42之間。 接下來，根據本實施例的鉸鏈機構1〇〇，藉由突起臂 部1 1 2，可以使旋轉軸部U 1位在前面板構件1 4的前方（圖 面下部），所以，可使具備了支持該旋轉軸部ill之鉸鏈 保持部1 3 0的開關門40，從（a )圖的關閉狀態開放到（b )圖的打開1 80度的狀態。對於該開關門40的開放動作’ 原本是種阻礙的階差減輕構件60，因爲開關門4〇之動作範 圍的部份被缺口部6 1所開放，所以可將開關門4〇大幅度打 開。 -16- 201111584 在本實施例中，藉由將鉸鏈軸部11 〇設置在形成於衣 物投入口 20之周圍的更低一階的凹部21，使開關門40的旋 轉軸部1 1 1側之端部44可抵住凹部2 1，而不會成爲開啓時 的障礙。如此一來，可減輕開關門40全體的伸出量。除此 之外，藉由從開關門40的前部緩緩連接到階差減輕構件60 的前面，形成弧狀的傾斜面’除了可減輕端部44抵接到凹 部2 1，還可減輕開關門4〇全體的伸出量。 如此一來，本實施例的洗衣機即爲一種具備：在筐體 內具有旋轉軸幾乎呈平行的旋轉槽，且在上述筐體的前面 具有將衣物取出放入至該旋轉槽的衣物投入口的滾筒式洗 衣機，其特徵爲：具備：開關門，該開關門係以可開啓之 方式來設置，在上述衣物投入口的單側具有鉸鏈機構部， 在另一側具有鎖定機構部；以及包圍該開關門之周圍的階 差減輕構件，上述鉸鏈機構部係使該旋轉軸位在比上述筐 體之前面更爲前方的位置，上述階差減輕構件係具有使開 關門之前面部與上述筐體之前面部連續的傾斜面，又在對 應於上述鉸鏈機構部與上述鎖定機構部的兩側，具備凹狀 的缺口部。藉由如此，可使朝前方突出的開關門調合於筐 體的前面，除了可減輕其突出感，將手放在開關門的一邊 ，還可將該開關門大幅度打開。 此時，利用使上述階差減輕構件爲左右對稱的形狀， 即可輕鬆地改變開關門左開或右開。又，上述開關門具有 圓形的外觀，可使包圍該開關門的階差減輕構件成爲環狀 -17- 201111584 甚至，在上述衣物投入口的周圍形成了比其他筐體面 更深入的凹部，在將上述開關門設定爲對應於上述凹部的 尺寸時，還藉由在上述凹部內設置上述鉸鏈機構部與上述 鎖定機構部，可減輕開關門全體的突出尺寸。 【圖式簡單說明】 第1圖係本發明之洗衣機的槪略構造圖。 第2圖係本發明之洗衣機的外觀圖。 第3圖係本發明之洗衣機的階差減輕構件的外觀圖。 第4圖係本發明之洗衣機的鉸鏈軸部之附近的部份剖 面圖》 第5圖係顯示本發明之洗衣機之開關門的動作狀態的 部份剖面圖。 第6圖係以往之洗衣機的剖面圖。 【主要元件符號說明】 1 :洗衣機 2 :洗衣槽 3 ’·外槽 4 :內槽 5 ·開口部 6 :波紋管 10 :筐體 1 1 :基座筐體 -18- 201111584 12 :前殼體 1 3 :頂板 1 4 :前面板構件 1 5 :操作面板構件 2 〇 :衣物投入口 2 1 :凹部 40 :開關門 41 :前框 42 :後框 43 :透明窗 44 :端部 60 :階差減輕構件 6 1 :缺口部 62 :旋鎖部 63 :內側的緣部 1 〇 〇 :鉸鏈機構 1 1 〇 :鉸鏈軸部 1 1 1 :旋轉軸部 1 1 2 :突起臂部 1 1 3 :基座構件 1 3 0 :鉸鏈保持部 1 5 0 :開閉鎖定機構 160 :桿機構部 1 6 1 :可動桿 -19 201111584 1 6 2 :握把 1 8 0 :桿嵌合受部 1 8 1 :嵌合穴部 -20-[Technical Field] The present invention relates to a drum type washing machine having a cylindrical rotary groove in which a rotating shaft is disposed at almost a horizontal position in a casing, and particularly relates to a garment provided in front of a casing. The drum type washing machine having the drying function is taken out and placed in the clothes input port of the above-mentioned rotary groove. [Prior Art] Conventionally, a drum-type washing machine is generally provided with a cylindrical rotating groove in which a rotating shaft is disposed almost horizontally, and a garment is taken out from the front surface of the casing. Rotate the clothes inlet of the slot. This conventional strategy structure is shown in Fig. 6. Here, Fig. 6 is a cross-sectional view of a conventional drum type washing machine. In the sixth embodiment, the conventional drum type washing machine 300 is provided with a washing tank 311 in a box-shaped casing 31, and a laundry input port 3 for putting the laundry into the washing tank 31 is provided in front of the casing. 0. The washing tank 3 1 1 is composed of: an outer groove 312 supported by the casing 310; and a rotary groove 3 1 4 rotatably provided in the outer groove 3 1 2 by a driving motor 313 Composition. The rotary shaft 3 1 5 of the drive motor 3 1 3 is attached to the back side of the outer tub 3 2 in a slightly horizontal shape. The rotary groove 3 1 4 is cylindrically mounted on the rotating shaft 3 15 with its axial center in a lateral position. The front surface of the rotary groove 3 1 4 and the outer groove 3 1 2 has a circular opening. The opening and closing door 3 3 0 is provided in the opening portion 316 by a clothes inlet port 3 2 被 provided on the front side of the casing. The opening portion 316 of the outer groove 312 and the clothes insertion opening 3 2 0 ' are connected by a bellows 3 1 7 201111584 of a flexible member provided around the outer groove 312 so as not to leak water. The switch cover 3 3 0 is a transparent window 33 formed by heat-resistant glass or the like which is embedded in the opening portion 3 16 and protrudes inward, and supports the transparent window 33 1 in a circular or quadrangular shape. The door body 3 3 2 is formed. The door body 3 3 2 has a shape having a thickness d in order to support the transparent window 331, and is normally opened to the left side by a hinge mechanism 340 provided on the left side. The hinge mechanism 340 of the conventional drum type washing machine has two types of structures as shown in Figs. 6(a) and 6(b). The structure of Fig. 6(a) is such that a cover 332 having a thickness d is directly mounted on the front surface of the flat casing. According to this configuration, the rotation axis P of the hinge mechanism 340 can be easily disposed in front of the casing 310. Therefore, the switch cover 330 can be largely opened by centering the rotation axis P. However, since the lid body 332 having the thickness d protrudes directly toward the front surface of the casing 310, there is a great problem in the installability or the design surface. Further, the conventional structure of Fig. 6(b) is such that a concave shape is formed around the laundry inlet 320, and the lid 332 is embedded in the recess. According to this configuration, although the problem of the mountability or the design surface can be greatly improved, in order to greatly open the switch cover 303, it is necessary to use the hinge mechanism 340 having the arc-shaped arc-shaped arm portion 341. Therefore, the hinge mechanism The enlargement or strength of 3 40 has become a new topic.

[Embodiment] Referring to FIG. 1 to FIG. 5Fig. 'Specification of the washing machine of the present invention is as follows. In the description, the same portions, arrows, and the like are denoted by the same reference numerals, and the description thereof will be omitted. First, the schematic configuration of the washing machine of the present embodiment will be described with reference to Fig. 1. Here, the first drawing is a schematic structural view of the washing machine of the present invention. In the first embodiment, the washing machine shown by the reference numeral 1 is a drum type washing machine in which a cylindrical washing tank (not shown) is disposed in a box-shaped casing 10. In the present embodiment, the casing 10 is composed of a base casing 11 constituting a frame of the box-shaped casing 10, a front casing 12 covering the front surface of the casing 11, and a top surface of the casing 11. The top plate 13 is constructed. The front case 12 is composed of a front panel 14 formed by press working of a steel sheet, and an operation panel member 15 formed of a resin material, which is provided on the upper portion of the front panel member 14 and is formed by these members. It is attached to the base housing 1 1 by a screw or the like (not shown). A garment opening 20 having a circular opening is formed in the front panel 14 , and the circular opening and closing door 40 is opened and closed by the hinge mechanism 1 〇〇 and the opening and closing locking mechanism 150 so as to be covered. The laundry is put into the port 20. That is, the switch door 40 is provided to the casing 10 by means of a hinge mechanism 100 provided at the left end, and can be opened and closed to the left, and opened and closed by the right end. The locking mechanism 150 locks the locked state of the clothes input port 20. Here, the hinge mechanism 100 is composed of: a hinge shaft portion 1 1 0 provided on the casing 10 side; and a hinge guard 9 - 201111584 provided on the switch door 40 side 'supporting the hinge shaft portion n 0 Part 1 3 0 (Fig. 5). Further, similarly, the opening and closing lock mechanism 150 is composed of a lever mechanism portion 1 60 provided on the side of the switch door 40, and a lever fitting portion ι8 provided on the side of the casing 1 'the lever mechanism portion 160 is locked. Further, the frame of the switch door 40 is composed of an annular front frame 41 formed of a resin material, a ring formed by covering the back surface of the front frame 41, and a ring formed of a resin material. The rear frame 4 2 is supported between the rear frame 42 and the front frame 4 1 and is formed of a transparent window 43 formed of heat-resistant glass. The transparent window 43 is formed so as to be inserted into the clothes insertion opening 20 and protruded toward the inside. As shown in the lower left extension frame of Fig. 1, in the present embodiment, an annular recess 21 is formed around the clothes insertion opening 20, and the annular recess 21 is other than the front panel member I4. Further, the recessed portion is formed, and the hinge shaft portion 110 of the hinge mechanism 100 and the rod fitting receiving portion 180 of the opening and closing lock mechanism 150 are provided at the right and left positions of the recessed portion 21. The hinge shaft portion 110 provided in the recess portion 21 includes a pair of rotations that extend forward, and support one pair of the rotation shaft portions 111, and a pair of rotations provided at the front ends of the pair of protrusion arm portions 112. The shaft portion 1 1 1 is rotatably supported by a hinge holding portion 130 (Fig. 5) provided at an end portion of the switch door 40. On the other hand, the rod fitting receiving portion 180 provided in the concave portion 2 1 includes the fitting hole portion 181, and the movable rod 161 constituting the rod mechanism portion 160 is inserted into the fitting hole portion 181. The switch door 40 is brought into a locked state. One of the larger features of the washing machine 1 of the present embodiment is that an annular step reducing member 60 is provided around the laundry input opening 20, and the annular step-10-201111584 difference reducing member 60 is attached to the left and right. A pair of notch portions 61 are formed at the opposite positions. That is, the hinge mechanism 1 used in the present embodiment causes the pair of rotating shaft portions 11 1 to protrude forward from the front panel member 14 by the protruding arm portion 1 1 2 , thereby enabling the The opening and closing door 40 provided in the pair of rotating shaft portions 1 1 1 can be opened largely. Further, since the projecting arm portion 112 supports the pair of rotating shaft portions 1 1 1 in a simple structure, the strength can be obtained, and the hinge holding portion 13 that supports the rotating shaft portion 111 can also have a simple structure. However, in order to open the switch door 40 largely, for example, by opening 1 to 80 degrees, it is necessary to cause the pair of rotating shaft portions 1 1 1 to protrude largely forward. That is, it is necessary to cause the opening and closing door 40 to largely protrude from the front panel member 14 toward the front. Therefore, the design of the opening and closing door 4 that largely protrudes from the front panel member 14 is deteriorated, or there is a problem that an article collides with the end of the extended opening and closing door 40. In particular, such drum type washing machines are mostly embedded in the flow table of the system kitchen, so that the problem that the switch door 40 of the protruding shape is inconsistent with the neat system is also generated. Therefore, in order to solve the problem, the inventors of the present invention have adopted a configuration in which an annular step reducing member 60 is provided around the opening and closing opening door 4〇, and the front surface of the plane is used by the step reducing member 60. The panel member 14 and the step and the transition of the opening and closing door 4 that protrudes from the front panel member 14 are successively continuous. As a result, the above-described problem can be alleviated by the fact that the opening and closing of the opening and closing frame as shown in Fig. 1 can cause the opening and closing opening of the door 40 to be gently raised. In addition, the use of the annular step mitigation member 60 to surround the periphery of the switch door 40 can make the switch door 40 visually larger, allowing the user to have an impression of the size of the clothes input port 20, which can enhance the user. The sense of use. Further, by designing the ring-shaped step-relieving member 60 in -11 - 201111584 with various colors, the design can be improved. However, once the annular step reducing member 60 is used to surround the periphery of the protruding switch door 40, the problem that the opening and closing door 40 cannot be opened largely occurs. Therefore, the inventors of the present invention ensure the operation range of the opening and closing door 40 by forming the notch portion 61 at the step reducing member 60 adjacent to the relatively chain portion 110. Further, the inventors of the present invention have considered the manual switch of the switch door 40, and by forming the notch portion 61 in the step reducing member 60 adjacent to the opening and closing lock mechanism 150, it is possible to secure the hand of the user who manually opens the switch door 40. The range of motions inserted. Further, by forming the notch portion 61 for ensuring the operating range of the opening and closing door 40 and the operating range of the user's hand by the bilateral symmetry, it is possible to exhibit a design excellent. Furthermore, another major feature of the washing machine 1 of the present embodiment is that the switch door 40 can be easily opened to the left or by using the step reducing member 60 having the pair of notches 61 formed by left and right symmetry. Turn right. In the present embodiment, the hinge shaft portion 110 and the rod fitting receiving portion 180 are attached to the opposing position of the recessed portion 21, so that the mold which is formed by press-forming the front panel member 14 is replaced with the hinge shaft. The left and right positions of the hinge shaft portion 110 and the rod fitting receiving portion 180 can be changed by the simple structure existing in the portion of the rod 110 and the rod fitting receiving portion 180. Then, by opening and closing the switch door 40 to the right and left, the switch door 40 can be opened correspondingly to the left and right. Referring to Fig. 1 and Fig. 2 to Fig. 5, the details of the washing machine of this embodiment are as follows. -12- 201111584 The washing machine of this embodiment is as follows.
