在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
如图1-4所示，本发明的实施例介绍了一种滚筒洗衣机，包括外筒2和套装在外筒2内部的内筒3，内筒3上设有投放口，外筒2上设有敞口，投放口和敞口在内筒3轴向方向上相重叠设置；内筒3上安装有对应封闭投放口的第一门体30，外筒2上安装有开闭敞口的第二门体20。
本发明通过设置第一门体30，使洗衣机执行洗涤程序、内筒3旋转时，衣物始终在内筒3中滚动，避免了衣物卡在内筒3投放口与洗衣机机门10之间的空隙；同时，通过在外筒2敞口处设置第二门体20，使外筒2敞口自动封闭，令洗衣机外壳1与外筒2敞口之间可不设密封窗垫，避免了水流自外筒2敞口流出情况的发生。除此之外，本发明通过设置第一门体30保证了洗衣机执行洗涤程序时内筒3内部处于封闭状态，避免内筒3中的洗涤水由投放口溅射到外筒2内壁上，实现了洗衣机免清洗的目的。
其中，投放口和敞口在内筒3轴向上相重叠设置，即投放口设于内筒3轴向上的第一侧，外筒2和内筒3轴线呈同向延伸，敞口设于外筒2轴向上的、靠近内筒3第一侧的一侧；具体地，外筒2和内筒3均包括轴线呈前后延伸的圆筒状侧壁和封闭侧壁后端的底壁，敞口设于外筒2前侧，投放口设于内筒3前侧，内筒3可绕自身轴线旋转，外筒2筒壁底部设有排水口，第二门体20安装在内筒3上，第一门体30安装在外筒2上，第二门体20和第一门体30均为向外翻转打开、对应翻转关闭。
参阅图1-4，本实施例中，第一门体30至少覆盖投放口的全部，第一门体30与投放口内壁、和/或投放口外周的内筒3相密封接触。即第一门体30关闭时使投放口处完全密封。
本发明通过上述设置避免内筒3中的气体、液体自投放口处流至内筒3外部，进一步避免内筒3中的洗涤水由投放口溅射到外筒2内壁上。
参阅图1-4，本实施例中，第二门体20至少覆盖敞口的全部，第二门体20与敞口内壁和/或敞口外周的外筒2相密封接触。即第二门体20关闭时使敞口处完全密封。
本发明通过上述设置避免外筒2中的气体、液体自敞口处流至外筒2外部，进一步避免外筒2中的洗涤水流至外筒2外部影响洗衣机自身的使用或者洗衣机外部设备的使用。
参阅图1-4，本实施例中，第二门体20和第一门体30相互独立设置，即用户在拿取、投放衣物时，先打开第二门体20，再打开第一门体30，洗涤衣物时，先关闭第一门体30，再关闭第二门体20。
本发明通过使第一门体30和第二门体20相互独立，令第一门体30和第二门体20之间不相互影响，以适应用户不同的需求。
参阅图1-4，本实施例中，滚筒洗衣机包括外壳1，外筒2和内筒3安装于外壳1内部，外壳1上设有供第二门体20相对开闭的开口；优选的，开口、敞口与投放口同轴设置。
本发明通过上述设置优化了洗衣机外观。
具体地，外壳1包括前面板、上台面板、后背板、底板和侧板，以限定出容纳腔室，底板上安装有底脚，以支撑洗衣机，此不赘述，开口设于外壳1前侧。
参阅图1-4，本实施例中，内筒3和外筒2之间的空间经第二门体20打开时的敞口与外筒2和外壳1之间的空间相连通，即敞口与开口之间不设置普通滚筒洗衣机中的、用于密封敞口与开口之间的空隙的密封结构。
参阅图1-4，本实施例中，外壳1开口处对应安装有封闭开口的机门10。
本发明通过上述设置进一步优化了洗衣机外观。
具体地，机门10安装在外壳1上，机门10为向外翻转打开、对应翻转关闭。
参阅图1-4，本实施例中，机门10和第二门体20相互独立，即机门10和第二门体20相互独立，即用户在拿取、投放衣物时，先打开机门10，再打开第二门体20，洗涤衣物时，先关闭第二门体20，再关闭机门10。
本发明通过上述设置使机门10和第二门体20之间不相互影响，以适应用户不同的需求。
本实施例中，机门10和第二门体20之间设置联动机构，当机门10关闭、或打开外壳1的开口时，第二门体20跟随机门10翻转对应封闭、或打开外筒2的敞口，即用户在拿取、投放衣物时，打开机门10的同时第二门体20也打开，洗涤衣物时，关闭机门10的同时第二门体20也关闭。
本发明通过在机门10和第二门体20之间设置联动机构，令机门10和第二门体20同时打开、关闭，简化了用户投放、拿取衣物的操作。
具体地，机门10关闭后，机门10固定在外壳1上，机门10具有装饰作用。
参阅图1-4，本实施例中，内筒3为洗衣机执行洗涤程序时形成容纳洗涤水的密封容器。一些实施例中，内筒3为普通滚筒洗衣机的内筒。
参阅图2-4，本实施例中，机门10的外围和外壳1开口之间设有一圈减震件。其中，减震件为橡胶材质。
本发明通过上述设置减小了关闭机门10时的噪音，同时提高了机门10封闭开口的密封效果。
参阅图2-4，本实施例中，内筒3侧壁上设有提升筋9，提升筋9内部设有容纳腔，容纳腔壁面上设有与内筒3内部空间相连通的第一通孔和与内筒3和外筒2之间的空隙相连通的第二通孔93，容纳腔内部设有控制第一通孔和/或第二通孔93开闭的控制结构。
本发明通过上述设置，实现了内筒3为无孔内筒3、第一门体30关闭时内筒3中液体的排放，其中，第一通孔和/或第二通孔93关闭、第一门体30关闭时，内筒3内部处于完全封闭状态，避免内筒3中的洗涤水溅射到外筒2内壁上，第一通孔和第二通孔93打开、第一门体30关闭时，内筒3内部处于半封闭状态，内筒3中的洗涤水排放至内筒3和外筒2之间的空隙，同时避免内筒3中的洗涤水由投放口溅射到外筒2内壁上，第一通孔和第二通孔93打开、第一门体30打开时，内筒3内部处于打开状态，用户可在此时清理内筒3、外筒2，第 一通孔和/或第二通孔93关闭、第一门体30打开时，内筒3内部处于半打开状态，用户可在此时拿取、投放衣物。
具体地，第一通孔密布于容纳腔靠近内筒3内部的一侧，第二通孔93设于容纳腔靠近内筒3和外筒2之间的空隙的一侧，第二通孔93的数量较少，控制结构控制第二通孔93的开闭，提升筋9包括环绕内筒3轴线、均匀分布的多个，还包括沿内筒3轴向、均匀分布的多个。
