发明内容
发明所要解决的问题
本发明是在该背景下完成的，其目的在于提供一种立式洗衣机，其能减少外桶罩的上表面部处的污垢，实现外桶罩的美观的改善。
用于解决问题的方案
本发明是一种立式洗衣机，包括：外桶，具有筒状的外桶主体和外桶罩，所述形成有从上侧与所述外桶主体内连通的出入口，与所述外桶主体连接；洗涤桶，形成有从下侧与所述出入口对置的开口，配置于所述外桶内，收容经过所述出入口和所述开口被投入的洗涤物；盖，可转动地由所述外桶罩支承，打开/关闭所述出入口；锁定槽，设置于所述外桶罩中划分出所述出入口的内周面部；以及锁定突起，设置于所述盖的外周面部，能在后退位置和与处于所述后 退位置时相比更从所述外周面部突出的前进位置之间移动，配置于所述前进位置而嵌入所述锁定槽，由此将关闭所述出入口的状态的所述盖锁定。
此外，本发明的特征在于，在所述盖将所述出入口关闭的状态下，所述盖的所述外周面部被所述外桶罩的所述内周面部包围，所述外周面部的上端和所述内周面部的上端配置于同一高度位置。
此外，本发明的特征在于，在所述外桶罩形成有沿所述盖的转动轴线延伸的插入孔，所述盖具有能插入所述插入孔并沿所述转动轴线滑动的可动轴。
此外，本发明的特征在于，所述盖具有对用于关闭所述出入口的所述盖的转动施加阻力的阻尼器。
此外，本发明的特征在于，在所述外桶罩的上表面部中与所述插入孔相邻的位置，设置有向下侧凹陷而接纳所述盖的转动中心部的凹部，在所述凹部的内表面部设置有凸部，在所述转动中心部设置有在所述盖将所述出入口打开时与所述凸部卡合的卡合部。
发明效果
根据本发明，在形成于外桶的外桶罩上的出入口由盖打开/关闭的结构中，通过使设置于盖的外周面部的锁定突起配置在前进位置而嵌入外桶罩的锁定槽，由此，盖在将出入口关闭的状态下被锁定。如将锁定槽设置于外桶罩的上表面部，则污垢存留在锁定槽中而使得该上表面部容易被弄脏，然而，锁定槽不设置于该上表面部，而是设置于外桶罩中划分出出入口的内周面部。由此，能减少外桶罩的上表面部的污垢，实现外桶罩的美观性的改善。
此外，根据本发明，在盖将出入口关闭的状态下，盖配置在出入口处的外桶罩的内周面部的内侧，盖的外周面部的上端和外桶罩的内周面部的上端配置于同一高度位置。由此，盖的外周面部的上端和外桶罩的内周面部的上端平滑地相连，因此，不会在它们的上端之间产生容易存留污垢的高度差。因此，能减少外桶罩的上表面部中内周面部附近的污垢，实现外桶罩的美观性的改善。
此外，根据本发明，通过使盖的可动轴插入外桶罩的插入孔，使得盖以能绕可动轴转动的方式由外桶罩支承。可动轴能沿盖的转动轴线滑动。因此，能 使可动轴滑动而从插入孔中取下来，由此将盖从外桶罩取下来。由此，能以分离的状态搬运盖和外桶罩，因此，能防止例如搬运时对外桶罩产生的冲击传给盖。此外，能在盖和外桶罩分离的状态下容易地对它们进行维护。
此外，根据本发明，从阻尼器对用于关闭出入口的盖的转动施加阻力，因此，能缓慢地关闭盖。
此外，根据本发明，在外桶罩的上表面部中与插入孔相邻的凹部中接纳盖的转动中心部的结构中，当盖将出入口打开时，转动中心部的卡合部与凹部内的凸部卡合。由此，盖能维持打开的状态，因此，能防止盖擅自关闭。此外，在盖打开的状态下，这些卡合部和凹部隐藏在转动中心部的下侧从而不容易进入使用者的视野，因此，实现了外桶罩的美观性的改善。

在外桶罩3B中的出入口3E的后侧Y2的部分，从上侧Z1连接有与自来水龙头连接的供水路13。在供水路13的中途设置有例如由电磁阀构成的供水阀14。在外桶3的底壁3D，从下侧Z2连接有排水路15。在排水路15的中途设置有排水阀16。当在排水阀16关闭的状态下打开供水阀14时，从供水路13向外桶3内供水，由此能向外桶3内蓄水。当供水阀14关闭时，停止供水。当排水阀16打开时，外桶3内的水从排水路15排出到机外。
洗涤桶4例如为金属制，形成为比外桶3小一圈的有底圆筒状，内部能收容洗涤物Q。洗涤桶4同轴状地配置于外桶3内。收容于外桶3内的状态的洗涤桶4能绕作为其中心轴沿上下方向Z延伸的轴线J进行旋转。洗涤桶4具有：近似圆筒状的圆周壁4A，沿上下方向Z配置；底壁4B，从下侧Z2堵住圆周壁4A的中空部分；以及环状的环状壁4C，沿圆周壁4A的上端缘向轴线J侧突出。以下，将以轴线J为中心的径向称为径向R，径向R中当，将朝向轴线J的一侧称为径向内侧R1，将远离轴线J的一侧称为径向外侧R2。
圆周壁4A的内周面为洗涤桶4的内周面。圆周壁4A处于被外桶3的圆周壁3C包围的状态。底壁4B设置于洗涤桶4的下端。环状壁4C处于从下侧Z2与外桶3的外桶罩3B对置的状态。在环状壁4C的内侧形成有开口4D。开口4D位于洗涤桶4的上端，使圆周壁4A的中空部分向上侧Z1露出。开口4D处于从下侧Z2与外桶3的出入口3E对置并连通的状态。使用者经由敞开的开口2B、出入口3E以及开口4D，从上侧Z1将洗涤物Q投入取出洗涤桶4。
在洗涤桶4的圆周壁4A和底壁4B，形成有多个贯通孔4E，外桶3内的水还能经由贯通孔4E在外桶3与洗涤桶4之间往来从而蓄于洗涤桶4内。因此，外桶3内的水位与洗涤桶4内的水位一致。需要说明的是，贯通孔4E也可以不设置于圆周壁4A而只设置于底壁4B。
洗涤桶4的底壁4B形成为圆板状，在外桶3的底壁3D的上侧Z1与底壁3D隔开间隔地大致平行延伸。在底壁4B中的与轴线J一致的圆心位置，形成有贯通底壁4B的贯通孔4F。在底壁4B设有管状的支承轴17，该支承轴17包围贯通孔4F，同时沿着轴线J向下侧Z2延伸。支承轴17插通于外桶3的底壁3D的贯通孔3G，支承轴17的下端部位于底壁3D的下侧Z2。
波轮5形成为以轴线J为圆心的圆盘状，在洗涤桶4内配置于底壁4B上。在波轮5中的面向洗涤桶4的开口4D的上表面，设置有辐射状配置的多个叶片5A。在波轮5设置有从其圆心沿着轴线J向下侧Z2延伸的旋转轴18。旋转轴18插通于支承轴17的中空部分，旋转轴18的下端部位于外桶3的底壁3D的下侧Z2。
马达6为变频马达等电动马达。马达6在箱体2内配置于外桶3的下侧Z2。马达6具有以轴线J为中心进行旋转的输出轴19，将产生的驱动力从输出轴19输出。
离合器7介于支承轴17和旋转轴18各自的下端部与从马达6向上侧Z1突出的输出轴19的上端部之间。离合器7将马达6从输出轴19输出的驱动力选择性地传递给支承轴17和旋转轴18中的一方或双方。当来自马达6的驱动力传递至支承轴17时，洗涤桶4接受马达6的驱动力而绕轴线J进行旋转。当来自马达6的驱动力传递至旋转轴18时，波轮5接受马达6的驱动力而绕轴线J进行旋转。使用公知的传递机构作为离合器7。
立式洗衣机1包括由CPU和存储器构成并内置于箱体2内的微型计算机21。马达6、离合器7、显示操作部11、供水阀14以及排水阀16分别与微型计算机21电连接。微型计算机21使马达6接通而使其进行驱动，使马达6断开而使其停止。微型计算机21通过控制离合器7，将马达6的驱动力的传递目标切换为洗涤桶4和波轮5中的一方或双方。当使用者操作显示操作部11来选择运转条 件等时，微型计算机21接收该选择。微型计算机21控制显示操作部11的显示内容。微型计算机21对供水阀14和排水阀16的打开/关闭进行控制。
微型计算机21通过控制马达6、离合器7、供水阀14以及排水阀16的工作，执行洗涤运转。洗涤运转具有：对洗涤物Q进行清洗的清洗过程、清洗过程之后对洗涤物Q进行漂洗的漂洗过程以及漂洗过程之后使洗涤桶4旋转而将洗涤物Q脱水的脱水过程。立式洗衣机1也可以是在脱水过程之后还执行烘干洗涤物Q的烘干过程的洗干一体机。当使用者将洗涤物Q和洗涤剂投入洗涤桶4内并通过显示操作部11的操作来指示开始洗涤运转时，微型计算机21开始清洗过程。
随着清洗过程开始，首先，微型计算机21在排水阀16关闭的状态下持续地打开供水阀14，向洗涤桶4内供水，向洗涤桶4内蓄水至规定水位W。之后，微型计算机21在根据需要切换离合器7而使得马达6的驱动力传递至波轮5之后，通过使马达6进行驱动而使波轮5旋转规定的时间。由此，洗涤桶4内的洗涤物Q被旋转的波轮5搅拌清洗。而且，洗涤物Q的污垢被溶于水的洗涤剂分解。
搅拌清洗之后，微型计算机21切换离合器7后使马达6接通而使马达6的驱动力传递至洗涤桶4。由此，蓄有水的洗涤桶4例如以200rpm高速旋转。如此一来，在外桶3内产生涡流，外桶3内的水面S以轴线J侧的中央部变低而外周部变高的方式弯曲成U字状(参照图1的细双点划线)。由此，外桶3内的水在外桶3的圆周壁3C与洗涤桶4的圆周壁4A之间上升。上升的水穿过在外桶3的外桶罩3B的下表面处排列设置的肋22之间，一边螺旋状地旋转一边落下，从洗涤桶4的开口4D淋至洗涤桶4内(参照图1的粗双点划线箭头)。这时，外桶3的外桶罩3B的引导面3F将穿过肋22之间的水朝向开口4D向下引导。通过由洗涤桶4的旋转而产生的来自上侧Z1的洒水，还能可靠地洗涤开口4D侧的洗涤物Q。这样的洗涤桶4的旋转在持续规定时间之后停止，由此，清洗过程结束。
接着，作为清洗过程之后的脱水过程，也就是中间脱水过程，微型计算机21在排水阀16打开的状态下使洗涤桶4高速旋转。通过由该高速旋转而产生的 离心力，洗涤桶4内的洗涤物被脱水。从洗涤物渗出的水通过脱水而从排水路15排出到机外。在中间脱水过程的最后阶段，微型计算机21关闭排水阀16。
接着，微型计算机21执行漂洗过程。作为漂洗过程的一个例子，微型计算机21在打开排水阀16的状态下间歇地打开供水阀14，由此向洗涤桶4内喷淋供水。这种状态下，微型计算机21使洗涤桶4例如以30rpm低速旋转而使得喷淋遍布洗涤物Q的所有角落。由此，洗涤桶4内的洗涤物Q被全方位地漂洗。作为漂洗过程的其他例子，与清洗过程相同，微型计算机21在供水之后使波轮5旋转从而将洗涤物Q搅拌漂洗，之后使洗涤桶4旋转而从上侧Z1向洗涤物Q洒水。
可以执行两次以上漂洗过程，这种情况下，微型计算机21在漂洗过程与接下来的漂洗过程之间执行中间脱水过程，在最后的漂洗过程之后，执行与中间脱水过程相同的最终脱水过程。洗涤桶4的旋转条件可以不同于中间脱水过程和最终脱水过程，特别是，最终脱水过程中洗涤桶4的最高转速比中间脱水过程中洗涤桶4的最高转速高。随着最终脱水过程结束，洗涤运转结束。
接着，对外桶罩3B和盖12进行详细说明。图2是处于将外桶罩3B的出入口3E关闭的关闭状态的盖12和外桶罩3B的俯视图。外桶罩3B配置成大致左右对称。外桶罩3B的外周缘形成为近似圆形。在外桶罩3B中的靠后的区域，形成有与供水路13等连接的单个或多个连接口3H。在外桶罩3B中比连接口3H靠前侧Y1处形成有出入口3E。
图3是处于将外桶罩3B的出入口3E打开的打开状态的盖12和外桶罩3B的立体图。在外桶罩3B中划分出出入口3E的内周面部3I形成为半圆形状，具有向前侧Y1鼓出的圆弧状的前内周面部3J和沿左右方向X大致直线状延伸并与前内周面部3J的左右的后端相连的后内周面部3K。前内周面部3J一体地具有：从外桶罩3B的上表面部3BA中的与前内周面部3J的交界处向下侧Z2延伸的上纵壁3JA、从上纵壁3JA的下端向径向内侧R1突出的横壁3JB以及从横壁3JB中的径向内侧R1的端部向下侧Z2延伸的下纵壁3JC。俯视观察时上纵壁3JA、横壁3JB以及下纵壁3JC形成为向前侧Y1鼓出的圆弧状。在上纵壁3JA的前端部，设置有沿着上纵壁3JA的周向延伸并向前侧Y1凹陷的锁定槽 3L(同样参照后述的图13)。
后内周面部3K一体地具有：从外桶罩3B的上表面部3BA中的与后内周面部3K的交界处向下侧Z2延伸的上纵壁3KA、从上纵壁3KA的下端向径向内侧R1(这种情况下向前侧Y1)突出的横壁3KB以及从横壁3KB的前端向下侧Z2延伸的下纵壁3KC。上纵壁3KA沿左右方向X直线状延伸，架设于上纵壁3JA的左右的后端之间。俯视观察时上纵壁3KA和上纵壁3JA一边弯曲一边连续。横壁3KB沿左右方向X直线状延伸，架设于横壁3JB的左右的后端之间。俯视观察时横壁3KB和横壁3JB一边弯曲一边连续。下纵壁3KC沿左右方向X直线状延伸，架设于下纵壁3JC的左右的后端之间。俯视观察时下纵壁3KC和下纵壁3JC一边弯曲一边连续。
图4是盖12从外桶罩3B分离的状态下的主要部分立体图。在外桶罩3B的上表面部3BA中的从后侧Y2与后内周面部3K的中央部相邻的位置，设置有沿左右方向X直线状延伸并向下侧Z2凹陷的凹部3M。凹部3M从后内周面部3K的上纵壁3KA向后侧Y2凹陷。由此，上纵壁3KA被分离为凹部3M的左侧X1的左部分3KL和凹部3M的右侧X2的右部分3KR。外桶罩3B具有：从左部分3KL的右端向后侧Y2延伸的左纵壁3ML、从右部分3KR的左端向后侧Y2延伸的右纵壁3MR、架设于左纵壁3ML和右纵壁3MR的后端之间的里纵壁3MA以及架设于左纵壁3ML和右纵壁3MR的下端之间并与里纵壁3MA的下端相连的底壁3MB。左纵壁3ML、右纵壁3MR、里纵壁3MA以及底壁3MB构成凹部3M的内表面部。凹部3M被划分在沿左右方向X对置的左纵壁3ML和右纵壁3MR之间，被里纵壁3MA从后侧Y2划分，被底壁3MB从下侧Z2划分，向前侧Y1和上侧Z1敞开。
在外桶罩3B形成有左右一对插入孔3N。左侧X1的插入孔3N是形成于与凹部3M的左端相邻的左纵壁3ML并向左侧X1延伸的左插入孔3NL，右侧X2的插入孔3N是形成于与凹部3M的右端相邻的右纵壁3MR并向右侧X2延伸的右插入孔3NR。左插入孔3NL为正圆形状，与此相对，右插入孔3NR为不同于正圆的形状，例如是具有平行的直线状的两边和将它们连接的圆弧状的另外两边的近似矩形的长孔。底壁3MB具有从左右方向X观察时凹弯曲的上表面。在 底壁3MB的上表面设置有向上侧Z1稍微突出的凸部23。作为一个例子，一对凸部23在左右方向X上排列设置，各凸部23在左右方向X上是长尺寸。沿前后上下剖开后的凸部23的剖面形成为朝向上侧Z1变细的近似三角形状。凸部23既可以由与外桶罩3B相同的树脂等材料与外桶罩3B一体形成，也可以由不同于外桶罩3B的弹性材料形成并固定于外桶罩3B。
图5是关闭状态的盖12的俯视图。盖12配置成大致左右对称。以关闭状态为基准，盖12包括：具有与出入口3E相似的半圆形状的板状的主体部12A、设置于主体部12A的后端并沿左右方向X延伸的筒状的转动中心部12B以及将盖12在关闭状态下锁定或解除该锁定的锁定机构24。俯视观察时，在主体部12A中将上表面部和下表面部连接的外周面部12C形成为向前侧Y1鼓出的大致D字圆弧状。
图6是关闭状态的盖12的仰视图。以关闭状态的盖12为基准，在主体部12A的下表面部，设置有将外周面部12C包边的D字状的密封垫25。转动中心部12B设置为从外周面部12C中的沿左右方向X直线状延伸的后端缘向后侧Y2突出。在左右方向X上，转动中心部12B比外周面部12C的后端缘短。因此，转动中心部12B的左端位于该后端缘的左端的右侧X2，转动中心部12B的右端位于该后端缘的右端的左侧X1。
以关闭状态的盖12为基准，在转动中心部12B的后侧外周面设置有卡合部26。作为一个例子，一对卡合部26沿左右方向X排列设置，各卡合部26是在左右方向X上长尺寸并向后侧Y2稍微突出的凸部。沿前后上下剖开后的卡合部26的剖面形成为朝向后侧Y2变细的近似三角形状。卡合部26既可以由与转动中心部12B相同的树脂等材料与转动中心部12B一体形成，也可以由不同于转动中心部12B的弹性材料形成并固定于转动中心部12B。
盖12具有设置于转动中心部12B的左右一对转动轴27。盖12的转动轴线K穿过各转动轴27的中心。右侧X2的转动轴27是设置于转动中心部12B的右端部的阻尼器轴27R。阻尼器轴27R的右端部27RA处于从转动中心部12B的右端面向右侧X2突出的状态。与阻尼器轴27R关联地，盖12具有内置于转动中心部12B的右端部的阻尼器28。可以采用旋转阻尼器等公知的阻尼器作为阻 尼器28。阻尼器28将阻尼器轴27R可绕转动轴线K转动地支承，并且对阻尼器轴27R的转动施加阻力。由此，阻尼器轴27R相对于阻尼器28和转动中心部12B缓慢地相对转动。左右方向X上的阻尼器轴27R的位置被固定。
左侧X1的转动轴27是以能沿转动轴线K滑动的方式由转动中心部12B的左端部支承的可动轴27L。可动轴27L的左端部27LA处于从转动中心部12B的左端面向左侧X1突出的状态。在转动中心部12B的左端部的外周面(图6中为下侧Z2的外周面)，形成有左右方向X上长尺寸的凹陷12D。在凹陷12D的底部形成有沿左右方向X延伸并与转动中心部12B的内部空间连通的狭缝12E。
图7是图6的A－A剖视图。可动轴27L的左端部27LA形成为圆柱状。可动轴27L包括：主体部27LB，呈直径比左端部27LA大的圆柱状，从右侧X2与左端部27LA连结；以及右端部27LC，呈直径比主体部27LB小的圆柱状，从右侧X2与主体部27LB连结。在转动中心部12B的左端壁12L，形成有供左端部27LA插通的圆形的贯通孔12LA。左端壁12L的左表面为转动中心部12B的左端面。主体部27LB和右端部27LC配置于转动中心部12B内。右端部27LC的右侧部分插通于在转动中心部12B内固定于转动中心部12B的环状的衬套29内。
在主体部27LB的外周面设置有突出为爪状的操作部27LD。操作部27LD插通于转动中心部12B的左端部的凹陷12D内的狭缝12E，从狭缝12E露出至转动中心部12B的外周面。操作部27LD在左右方向X上具有游隙地插通于狭缝12E。因此，在操作部27LD能在狭缝12E内滑动的范围内，可动轴27L也能在左右方向X上滑动。螺旋弹簧等施力构件30以非接触的方式卷绕在右端部27LC并被压缩于主体部27LB与衬套29之间，由此始终向左侧X1对可动轴27L施力。
图8是可动轴27L的周边的盖12的立体图。当操作部27LD位于狭缝12E的左端时，可动轴27L位于最向左侧X1突出的前进位置。这时，可动轴27L的左端部27LA的大部分处于从转动中心部12B的左端壁12L向左侧X1突出的状态。左端壁12L作为止动件从左侧X1与主体部27LB接触，将转动中心部12B 中的狭缝12E的左端包边的部分作为止动件从左侧X1与操作部27LD接触(也参照图7)。由此，限制可动轴27L向前进位置的左侧X1移动。
图9是可动轴27L的周边的盖12的立体图。当操作部27LD位于狭缝12E的右端时，可动轴27L位于最向右侧X2后退的后退位置。这时，可动轴27L的左端部27LA处于退入转动中心部12B内的状态，左端部27LA的左端面与转动中心部12B的左端面大致在同一平面。使用者通过抓住操作部27LD使其滑动，能使可动轴27L在前进位置与后退位置之间滑动。在操作部27LD的表面设置有用于使使用者的手指不打滑的槽状的防滑部27LE。
在搬运立式洗衣机1时，盖12从外桶罩3B被取下并收容于专用的箱等，单独搬运。因此，能防止搬运时对外桶罩3B产生的冲击传至盖12。而且，在设置立式洗衣机1时，盖12由使用者装配于外桶罩3B。具体而言，参照图4，首先，使用者使盖12悬空，以使盖12的转动中心部12B位于外桶罩3B的凹部3M的上侧Z1。然后，使用者将转动中心部12B的右部分嵌入凹部3M的右部分，这时，将右侧X2的阻尼器轴27R从左侧X1插入外桶罩3B的右插入孔3NR中。接着，使用者在使操作部27LD滑动而使可动轴27L处于后退位置之后，将转动中心部12B的左部分嵌入凹部3M的左部分。于是，整个转动中心部12B被凹部3M接纳，可动轴27L从右侧X2与外桶罩3B的左插入孔3NL对置。这种状态下当使用者将手指从操作部27LD离开时，可动轴27L通过施力构件30(参照图7)的施力滑动至前进位置，从右侧X2插入左插入孔3NL中。由此，完成盖12向外桶罩3B的装配，盖12以能绕转动轴线K(参照图1)转动的方式由外桶罩3B支承(参照图3)。
当使用者按照与装配盖12时相反的顺序使操作部27LD滑动而将可动轴27L配置在后退位置之后将盖12抬起时，能将盖12从外桶罩3B取下来。由此，能以分离的状态搬运盖12和外桶罩3B。此外，能在盖12和外桶罩3B分离的状态下容易地对它们进行维护。特别是，外桶罩3B的整个凹部3M和盖12的整个转动中心部12B露出，因此，能去除凹部3M内的污垢或去除附着在转动中心部12B的污垢。
在盖12装配于外桶罩3B的状态下，左插入孔3NL和右插入孔3NR沿转动 轴线K延伸。左插入孔3NL是与可动轴27L的截面形状一致的正圆形状。因此，可动轴27L能相对于外桶罩3B中的左插入孔3NL的周缘部绕转动轴线K相对转动。另一方面，右插入孔3NR如前所述是不同于正圆的形状，阻尼器轴27R的截面形状与右插入孔3NR一致。因此，阻尼器轴27R固定在外桶罩3B中的左插入孔3NL的周缘部，能相对于转动中心部12B内的阻尼器28绕转动轴线K相对转动。阻尼器28通过对阻尼器轴27R的相对转动施加阻力，对用于打开/关闭外桶罩3B的出入口3E的盖12的转动施加阻力。由此，能缓慢地打开/关闭盖12。需要说明的是，在只优先考虑不使盖12用力关闭的情况下，阻尼器28至少对用于关闭出入口3E的盖12的转动施加阻力即可。
图10是外桶罩3B和关闭状态的盖12的立体图。在关闭状态的盖12中，主体部12A以水平的姿势堵住外桶罩3B的出入口3E。在这种状态下，在外桶罩3B中划分出出入口3E的内周面部3I在俯视观察时包围盖12的主体部12A的外周面部12C(也参照图2)。
图11是图2的B－B剖视图。详细而言，内周面部3I中，前内周面部3J的上纵壁3JA和后内周面部3K的上纵壁3KA(也参照图3)包围外周面部12C。关闭状态的盖12的主体部12A的上表面部中，几乎整个区域为水平面，主体部12A的上表面部的外缘为外周面部12C的上端12CA。外桶罩3B的上表面部3BA中将出入口3E包围的周边部3BB是随着靠近出入口3E而平缓上升的弯曲面。周边部3BB中将出入口3E包边的部分为外桶罩3B的内周面部3I的上端3IA。当盖12处于关闭状态时，外周面部12C的上端12CA和内周面部3I的上端3IA配置于同一高度位置。由此，上端12CA和上端3IA平滑地相连，因此，在这些上端之间不会产生容易存留污垢的程度的高度差。因此，能减少外桶罩3B的上表面部3BA的内周面部3I附近的污垢，实现外桶罩3B的美观性的改善。此外，当盖12处于关闭状态时，主体部12A的下表面部的外缘部从上侧Z1与前内周面部3J的横壁3JB和后内周面部3K的横壁3KB(也参照图3)对置。横壁3JB和横壁3KB各自与主体部12A的下表面部之间的间隙由设置于主体部12A的下表面部的密封垫25堵住。由此，盖12处于关闭状态时的出入口3E被密封，防止水从该间隙漏出。
图12是盖12的转动中心部12B的周边的示意性纵剖右视图。当盖12处于关闭状态时，设置于转动中心部12B的卡合部26如图12中用虚线所示，相对于外桶罩3B的凹部3M内的凸部23位于后上侧，详细而言位于向以转动轴线K为中心的逆时针方向D1偏移约90度的位置。一对卡合部26和一对凸部23在左右方向X上逐一位于同一位置(参照图4)。当使用者将关闭状态的盖12向以转动轴线K为中心的顺时针方向D2转动时，卡合部26接近在左右方向X上位于同一位置的凸部23并越过该凸部23。当盖12转动至打开状态时，各卡合部26如图12中实线所示，从顺时针D2的方向与对应的凸部23卡合。这时，也可以是，卡合部26不与凸部23接触，在卡合部26与凸部23之间存在间隙。总之，通过卡合部26与凸部23的卡合，盖12能维持盖12的打开状态而自立，因此，能防止盖12擅自关闭。
盖12中，至少转动中心部12B通过将第一部件12BA和第二部件12BB组合并用左右一对螺钉B(参照图4)固定而构成。需要说明的是，在转动中心部12B装配有覆盖螺钉B的遮挡用的帽35(参照图4)。卡合部26配置于第一部件12BA与第二部件12BB的边界的周边。该边界始终配置于凹部3M内。因此，在盖12打开的状态下，相互卡合的卡合部26和凹部3M通过隐藏于转动中心部12B的下侧Z2而不容易进入使用者的视野(也参照图3)。因此，能实现外桶罩3B的美观性的改善。转动中心部12B中螺钉B的周边的区域是第一部件12BA和第二部件12BB不容易分离的高刚性区域。由于各卡合部26在左右方向X上与螺钉B配置在同一位置，因此配置于该高刚性区域(参照图4)。因此，能防止卡合部26破损，实现卡合部26的耐久性的提高。
图13是包括图2的C－C剖面的主要部分立体图。最后，对锁定机构24进行说明。以关闭状态的盖12为基准，锁定机构24包括：锁定突起31，设置于主体部12A的外周面部12C的前端部；施力构件32，对锁定突起31向前侧Y1施力；以及杆33，设置于主体部12A的上表面部的前端，根据使用者的操作使锁定突起31向后侧Y2移动。在主体部12A的前端部设置有中空部分12F。在外周面部12C的前端部形成有从前侧Y1与中空部分12F连通的开口12G。在主体部12A设置有从外周面部12C的前端部向后上侧倾斜延伸的前支承部12H和配置于前支承部12H的后侧Y2并从主体部12A向上侧Z1突出的后支承部 12I。前支承部12H与后支承部12I之间的空间构成中空部分12F的上区域。在后支承部12I的下端设置有在中空部分12F中向前侧Y1突出的凸起12IA。
锁定突起31一体地具有沿前后方向Y延伸的顶端部31A、从顶端部31A的后端向上侧Z1突出的止动件31B以及从顶端部31A的后端向后侧Y2延伸的根部31C。止动件31B和根部31C收容于主体部12A的中空部分12F的下区域。顶端部31A从后侧Y2插通于主体部12A的外周面部12C的开口12G。在顶端部31A的下表面的前端部形成有倒角部31AA。在根部31C设置有向后上侧倾斜并从后侧Y2与止动件31B对置的倾斜面31CA和从前侧Y1与后支承部12I的凸起12IA对置的凸起31CB。图13所示的锁定突起31位于前进位置。前进位置的锁定突起31中，顶端部31A的大致前半部分从盖12的外周面部12C的开口12G向前侧Y1突出。此外，止动件31B从后侧Y2与前支承部12H的下端接触，由此限制锁定突起31向前进位置的前侧Y1移动。锁定突起31能后退至前进位置的后侧Y2的后退位置(未图示)。也就是说，锁定突起31能在前进位置与后退位置之间移动。后退位置的锁定突起31中，顶端部31A的大致前半部分被收纳在开口12G内，因此，与位于前进位置时相比，几乎不会从盖12的外周面部12C突出。
施力构件32例如是螺旋弹簧，收容于主体部12A的中空部分12F。施力构件32被压缩在锁定突起31的根部31C的凸起31CB与后支承部12I的凸起12IA之间，朝向前侧Y1的前进位置对锁定突起31施力。
杆33具有在前支承部12H的后侧Y2沿上下方向Z配置的按压部33A和从按压部33A的上端向后上侧倾斜延伸的操作部33B。按压部33A的下端处于从前侧Y1和上侧Z1与锁定突起31的根部31C的倾斜面31CA接触的状态。杆33以不会脱离的方式由前支承部12H支承。在这种状态下，当操作部33B上升时按压部33A下降，当操作部33B下降时按压部33A上升。图13所示的杆33处于待命位置。待命位置的杆33中，操作部33B以大致平行于前支承部12H的姿势从上侧Z1与后支承部12I的上端接触，由此使杆33保持在待命位置。在杆33处于待命位置的状态下，当使用者抓住操作部33B并抬起时，按压部33A一边下降一边将根部31C的倾斜面31CA向后侧Y2按压，因此，锁定突起31 从前进位置后退至后退位置。当使用者将手指从操作部33B离开时，锁定突起31因施力构件32的施加力而从后退位置前进至前进位置，这时倾斜面31CA将按压部33A上推，因此，杆33返回至待命位置。
如图13所示，当盖12处于关闭状态并且锁定突起31处于前进位置而杆33处于待命位置的情况下，锁定突起31的顶端部31A从后侧Y2嵌入外桶罩3B的内周面部3I的锁定槽3L。由此，盖12在关闭状态下被锁定。这种状态下当使用者抬起杆33的操作部33B时，锁定突起31后退而从锁定槽3L脱离，因此盖12的锁定被解除。因此，使用者通过进一步抬起操作部33B，能使盖12转动至打开状态。另一方面，当使用者将打开状态的盖12推向跟前时，盖12因自重而向前侧Y1转动。这时，锁定突起31为了使在外桶罩3B的上表面部3BA包围出入口3E的周边部3BB向下侧Z2越过，从前进位置瞬间后退。当锁定突起31越过周边部3BB时，锁定突起31的顶端部31A的倒角部31AA与周边部3BB接触，因此，锁定突起31不会被周边部3BB卡住，能顺利地越过周边部3BB。并且，当盖12转动至关闭状态时，锁定槽3L位于锁定突起31的前端，因此，锁定突起31通过施力构件32的施加力返回前进位置而嵌入锁定槽3L。
研究一个比较例，其不同于本实施方式，锁定槽3L设置于外桶罩3B的上表面部3BA。在该比较例中，污垢存留在锁定槽3L中，由此上表面部3BA容易被弄脏。另一方面，在本实施方式中，锁定槽3L不设置于上表面部3BA，而是设置于外桶罩3B中划分出出入口3E的内周面部3I。因此，容易存留污垢的凹凸从上表面部3BA消失。由此，能减少上表面部3BA处的污垢。进而，由于内周面部3I不容易进入使用者的视野，因此即使污垢附着于锁定槽3L，该污垢也不易显眼。以上的结果是，实现了外桶罩3B的美观性的改善。此外，如果是凹凸少的上表面部3BA，则容易维护，能减少投取时挂住洗涤物Q的情况。
本发明不局限于以上说明的实施方式，可以在技术方案所述的范围内进行各种变更。
例如，也可以是，盖12中的左右的转动轴27双方与阻尼器轴27R同样构成，或者与可动轴27L同样构成。
立式洗衣机1中的洗涤桶4的轴线J在上述的实施方式中以沿着上下方向Z 垂直延伸的方式配置(参照图1)，但是立式洗衣机1中也包括轴线J相对于上下方向Z稍微倾斜地配置的结构。
