如图1-6所示，本发明提供一种洗衣机的内筒结构，包括筒体1和封闭筒体1轴向一端的筒底2，筒体1的内周与筒底2的外周相抵接，筒体1的内周与筒底2的外周具有一圈重叠部，筒体1与筒底2的重叠部分设穿孔3，穿孔3处设密封结构5，密封结构5用于对筒体1和筒底2之间间隙与穿孔3相连通处进行密封。
本发明的实施例中，通过在筒体1与筒底2重叠部上的穿孔3处设密封结构5，密封结构5能够对筒体1和筒底2之间间隙与穿孔3相连通处进行密封， 提高筒体1与筒底2在穿孔3处的密封性，减少内筒洗涤水的泄漏。
筒体1和筒底2构成洗衣机的内筒，内筒可为无孔内筒，内筒用于盛放洗涤水；内筒还可为有孔内筒，洗衣机还包括外筒，内筒设有外筒内，内筒和外筒的之间的空间盛放洗涤水，洗涤水经内筒上的孔进入内筒内，洗衣机可为波轮洗衣机或滚筒洗衣机；穿孔3设于筒体1与筒底2的重叠部，也就是穿孔3设于筒底2与筒底2的周壁上，具体地，筒底2的周壁上设第一穿孔31，筒体1的周壁上设第二穿孔32，第一穿孔31和第二穿孔32形成穿孔3，第一穿孔31与第二穿孔32经固定件实现筒体1的内周与筒底2的外周的固定连接，第一穿孔31和第二穿孔32均为冲压的方式形成，固定件可为螺钉，筒体1和筒底2在第一穿孔31和第二穿孔32装配处易出现洗涤水泄漏，第一穿孔31和第二穿孔32相当于沿筒体1的径向延伸，第一穿孔31和第二穿孔32同轴设置。
此外，还可是筒体1的外周与筒底2的内周相互抵接，筒体1与筒底2的重叠部分设穿孔3，穿孔3处设密封结构5。
如图1-3所示，本发明的实施例中，筒底2的外侧设支撑件4，密封结构5夹持于支撑件4与穿孔3之间。
本发明的实施例中，筒底2相对筒体1内部具有内侧和外侧，筒底2的外侧设支撑件4，支撑件4上设沿轴向延伸的转动轴，转动轴与电机的电机轴连接，电机驱动转动轴转动，从而带动内筒转动，因此，支撑件4一方面起到传动的作用，另一方面用于对筒底2进行支撑，增加筒底2的强度，减少内筒转动中的晃动；
在此基础上，密封结构5夹持于支撑件4与穿孔3之间，支撑件4配合穿孔3夹持密封结构5，使得密封结构5能够比较紧实地密封穿孔3处，增强穿孔3处的密封性；
具体地，由于支撑件4设于筒底2上，因此，密封结构5夹持于支撑件4与第二穿孔32之间，密封第一穿孔31和第二穿孔32之间的装配间隙；
如图3所示，进一步地，筒底2的外周向筒体外轴向弯折形成一圈折边211，折边211的外周与筒体1的内周相抵接，筒体1的内周与折边211的外周形成一圈重叠部，支撑件4设于折边211围成的圈内，穿孔3设于该重叠部分上，第二穿孔32设于折边211上，折边211对支撑件4具有限位的作用，提高支撑件4在筒底2上的稳定性；折边211与筒底相对的一侧向筒体内弯折形成辅助折边，筒体的周臂嵌入折边211与辅助折边之间，辅助折边的内周与筒体1的外周相抵接，从而实现筒体1与筒底2之间的密封安装。
筒底2为法兰盘211，筒底2为圆盘状，筒体1为圆筒状，筒底2与筒体1同轴设置，一圈折边211为圆环状。
如图1、图2、图3和图6所示，本发明的实施例中，支撑件4具有若干从筒底2的轴心向筒底2的边缘径向凸伸形成的支撑臂411，密封结构5夹持于支撑臂411的末端与穿孔3之间。
本发明的实施例中，具体地，支撑件4包括与筒底2同轴、呈圆形的中心体，中心体的外周设若干径向延伸的支撑臂411，支撑臂411从筒底2的轴心延伸至筒底2的边缘，若干支撑臂411沿中心体的周向呈一圈分布，具体地，支撑件4为三脚架，三脚架具有三个支撑臂411，三个支撑臂411之间的夹角为120度，三个支撑臂411布满整个筒底2的周向区域，支撑件4为三脚架，在简化支撑件4的结构的同时，三个支撑臂411的排布形式能够增加支撑件4自身的稳固性；支撑体向筒体1外轴向延伸形成转动轴，转动轴在图中未示出；三脚架设于折边211围成的圈内，筒底2上设与三脚架的结构适配的装配槽，三脚架装于装配槽内，装配槽进一步地三角架41进行定位。
密封结构5夹持于支撑臂411的末端与穿孔3之间，具体地，支撑臂411径向延伸，支撑臂411为方形，支撑臂411外周朝向穿孔3的一侧与第二穿孔32之间夹持密封结构5。
如图3所示，本发明的实施例中，支撑臂411末端设与穿孔3装配的连接孔412，密封结构5夹持于连接孔412与穿孔3之间。
本发明的实施例中，为了实现支撑臂411固定在筒底2上，支撑臂411稳固地在筒底2上，于是，支撑臂411在与筒底2和筒体1重叠部分的穿孔3正对的地方设连接孔412，具体地，连接孔412正对第一穿孔31和第二穿孔32，连接孔412通过螺钉等固定件与第一穿孔31和第二穿孔32装配，实现支撑臂411固定在筒底2上，筒底2固定在筒体1上，具体地，密封结构5夹持在连接孔412与第二穿孔32之间；
具体地，连接孔412、第一穿孔31和第二穿孔32均为圆形孔，连接孔412、第一穿孔31和第二穿孔32三者同轴设置。
如图3所示，本发明的实施例中，至少部分密封结构5嵌入连接孔412内，密封结构5的外周与连接孔412的内周相抵接。
本发明的实施例中，至少部分密封结构5嵌入连接孔412内，连接孔412能够对密封结构5进行定位，确保密封结构5夹持在连接孔412和第二穿孔32之间的同时，提高密封结构5在连接孔412和第二穿孔32之间的稳定性，从而提高密封结构5对第一穿孔31和第二穿孔32装配间隙的密封强度；
密封结构5的外周与连接孔412的内周相抵接，避免洗涤水从密封结构5与连接孔412之间的间隙中外漏，提高密封结构5的密封性。
如图3、图4和图5所示，本发明的实施例中，密封结构5完全嵌入连接孔412内，穿孔朝向连接孔412的一侧设环形凸出部6，环形凸出部6嵌入连接孔 412内、与密封结构5相抵接。
本发明的实施例中，密封结构5完全嵌入连接孔412，进一步增加密封结构5夹持在连接孔412和穿孔3之间的稳定性，穿孔3的外周边缘朝向连接孔412凸伸形成环形凸出部6，环形凸出部6在筒体1和筒底2的径向上凸伸，环形凸出部6嵌入连接孔412内，环形凸出部6与密封结构5相互抵接，进一步增强密封结构5对第一穿孔31和第二穿孔32装配处的密封强度，从而实现连接孔412和穿孔3对密封结构5的夹持；
具体地，筒体1的周壁在第一穿孔31处设径向凸伸的第一环形凸出部61，折边211在第二穿孔32处设径向凸伸的第二环形凸出部62，第一穿孔31、第二穿孔32和连接孔412在装配时，第一环形凸出部61嵌入第二穿孔32内，第二环形凸出部62嵌入连接孔412内与密封结构5相抵接，第一环形凸出部61嵌入第二穿孔32内，减小第一穿孔31和第二穿孔32之间的装配间隙，第二环形凸出部62嵌入连接孔412内，减小第二穿孔32与连接孔412之间的装配间隙的同时，增强第二连接孔412和连接孔412对密封结构5的夹持强度；
第一穿孔31、第一环形凸出部61、第二穿孔32、第二环形凸出部62、连接孔412同轴设置，密封结构5为橡胶材质，可无需有开孔，装配时，密封结构5嵌入连接孔412内，第一环形凸出部61嵌入第二穿孔32内，第二环形凸出部62嵌入连接孔412内与密封结构5相抵接，螺钉等固定件依次穿出第一穿孔31、第一环形凸出部61、第二穿孔32、第二环形凸出部62、密封结构5和连接孔412实现将筒体1、筒底2、支撑件4和密封结构5的固定连接，从而实现密封结构5对第一穿孔31和第二穿孔32之间的装配间隙的密封。
如图3所示，本发明的实施例中，连接孔412为阶梯孔，密封结构5嵌入连接孔412内、与连接孔412内的台阶4121相接。
本发明的实施例中，连接孔412为阶梯孔，连接孔412从筒底2的轴心向筒底2的外周边缘方向分为第一阶梯孔和第二阶梯孔，第一阶梯孔的径向尺寸小于第二阶梯孔的径向尺寸，第一阶梯孔与第二阶梯孔的过渡处设台阶4121，密封结构5完全嵌入第二阶梯孔内与台阶4121相抵接；
之所以连接孔412为阶梯孔是因为在密封结构5完全嵌入连接孔412内后，为了增加密封结构5在连接孔412内的稳定性，避免螺钉固定时密封结构5易出现变形而导致的密封结构5强度下降，因此，密封结构5与台阶4121相抵，台阶4121对密封结构5具有支撑稳固的作用。
具体地，密封结构5为密封圈51，密封圈51的外周与连接孔412的内周相抵接，密封圈51的一端面与环形凸出部6相抵接，另一端面与台阶4121相接，密封结构5为密封圈51，密封圈51上设开孔，开孔与第一穿孔31、第二穿孔32同轴设置；密封圈51的一端面与台阶4121相抵，密封圈51的另一端面与第二环形凸出部62相抵，密封圈51的外周与第二阶梯孔的内周相抵，密封圈51的内周形成开孔供螺钉等固定件穿过；密封圈51与环形凸出部同轴，环形凸出部开孔的径向尺寸大于密封圈51开孔的径向尺寸、小于密封圈的径向尺寸。
如图6所示，本发明的实施例中，支撑臂411向筒体1内凹陷形成径向延伸的凹陷部413，连接孔412设于凹陷部413的侧壁上。
本发明的实施例中，支撑臂411向下凹陷形成凹陷部413，凹陷部413增加了支撑臂411的结构强度，从而使得内筒能够比较平稳地转动；
凹陷部413与支撑臂411的延伸方向一致，凹陷部413延伸至支撑臂411的末端，连接孔412设于凹陷部413上，避免支撑臂411在连接孔412处固定时易出现变形；
凹陷部413沿径向延伸的方向分为第一部分和第二部分，第一部分和第二 部分从筒底2的轴心向筒底2的外周边缘的方向排布，第一部分的宽度小于第二部分的宽度，穿孔3设于尺寸较大的第二部分上。
进一步地，凹陷部413的底壁向上凸伸形成凸出部414，凸出部414径向延伸，凸出部414延伸方向的一端与凹陷部413的侧壁相抵接，连接孔412贯通凹陷部413的侧壁和凸出部414，凸出部414在增强支撑臂411的结构强度的同时，进一步增强了支撑臂411在连接孔412处的强度；
凸出部414沿径向延伸，连接孔412贯穿凸出部414和凹陷部413的侧壁，增加了连接孔412的长度，减少支撑臂411在固定安装时易变形的情况。
具体地，凹陷部413的底壁向上凸伸形成两个凸出部414，两个凸出部414沿筒体1的周向分布，两个凸出部414之间设加强筋415，凸出部414延伸方向的第一端与凹陷部413的侧壁抵接，加强筋415分别与两个凸出部414延伸方向的第二端连接，加强筋415进一步增强了支撑臂411在连接孔412处的结构强度。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
