具体实施方式
下面结合附图对本发明的具体实施方式作进一步详细的描述。
实施例一
如图1所示，一种内筒三角架，一般安装在洗衣机内筒1的底部，以提高洗衣机内筒1的强度，具体包括，一用于与洗衣机内筒1连接的本体2，所述本体2为三角形结构，包括三个辐射状延伸的支撑臂，所述支撑臂呈120度角分布，并具有一定的厚度。
结合图2和图3所示，所述本体2的一侧面向洗衣机内筒1，另一侧背对洗衣机内筒1，在本体2安装在洗衣机内筒1上后，两者之间会存在一定的空隙，为避免脏物随洗涤水进入至该空隙中，所述本体2上的与洗衣机内筒1相接触的部位设有凸起的用于阻止洗涤水进入本体2与洗衣机内筒1之间区域的密封结构，该封闭结构沿着本体2的轮廓分布，并通过与洗衣机内筒1接触的方式，以阻挡脏物进入本体2与洗衣机内筒1之间的空隙中。
结合图4至图6所示，优选地，为避免线屑等杂物吸附在本体2的表面，所述本体2背对洗衣机内筒1的一侧为平整光滑的表面，以使线屑等杂物无法吸附在该表面上，所述本体2面向洗衣机内筒1的一侧设置有多个加强筋5，当所述本体2安装在洗衣机内筒1上后，加强筋5将隐藏在两者之间，有效提高了本体2的强度，同时不会与线屑等杂物接触。
所述密封结构包括，设置在本体2的外边缘，且面向洗衣机内筒1一侧的条形安装槽3，以及设置在安装槽3内，用于与洗衣机内筒1表面接触的密封件7，所述密封件7具有一定的弹性，可压触在洗衣机内筒1的表面，所述密封件7可以为橡胶材料或其他可用于密封的弹性材料。
所述本体2背对洗衣机内筒1的一侧设有沿其表面平行延伸出的凸缘4，所述凸缘4沿着本体2的外边缘设置，凸缘4面向洗衣机内筒1方向的一侧为内端面，所述安装槽3设置在内端面上，并向洗衣机内筒1方向凸起。
优选地，所述凸缘4与本体2为一体成型，凸缘4的厚度小于本体2在轴向方向上的宽度。
所述安装槽3由两道并排凸起的条状筋构成，两条条状筋之间相隔一定距离，所述密封件7卡在两道条状筋之间，并高于所述条状筋。当内筒三角架安装在洗衣机内筒1上时，所述密封件7被条状筋和洗衣机内筒1共同挤压变形，形成密封式接触。
所述安装槽3为三组，并对应分布在支撑臂的两侧，每组安装槽3由其中一个支撑臂的端部起始延伸至另一支撑臂的端部结束。所述安装槽3贯穿于支撑臂的整个侧边，使得支撑臂的两侧与洗衣机内筒1之间无缝连接，达到密封的作用。
实施例二
结合图7所示，为达到更好的密封效果，所述安装槽3由至少三道并排凸起的条状筋构成，并形成至少两道并排的安装槽3，所述密封件7为一体或分体式结构，并相应卡在条状筋之间，所述密封件7高于所述条状筋，以与洗衣机内筒1表面接触。
具体地，所述密封件7为一体式结构时，可以选用具有多个凸起安装结构8的多排密封条，每个凸起安装结构8对应卡在一个安装槽3内。所述密封件7为分体式结构时，可以在每个安装槽3内安装一条矩形密封条，以形成多个密封接触面，提高密封效果。
一种配置有上述两种实施例中的内筒三角架的滚筒洗衣机，所述滚筒洗衣机，一般还包括，外壳、设置在外壳内的洗衣机外筒和洗衣机内筒1，以及动力装置和控制系统，所述洗衣机内筒1的底部设有与内筒三角架配合的安装结构，优选地，所述安装结构为与内筒三角架形状相匹配的凹槽，所述内筒三角架通过扣合的方式固定安装在洗衣机内筒1的底部，并通过螺钉国定。所述内筒三角架上的密封结构与洗衣机内筒1表面接触，形成封闭式连接。
为使动力装置与洗衣机内筒1连接，所述洗衣机内筒1的底部设有第一中心通孔11，所述内筒三角架的中心设有第二中心通孔21，第一中心通孔11与第二中心通孔21同轴设置，所述动力装置的转轴穿过第二中心通孔21并伸入至第一中心通孔11内与洗衣机内筒1连接，以驱动洗衣机内筒1转动。
所述第二中心通孔21的边缘设有凸起的环形凸缘6，所述环形凸缘6的端面与洗衣机内筒1的第一中心通孔11密封性接触。
所述内筒三角架的支撑臂的端部与洗衣机内筒1底部的内圆周侧接触，在该端部和洗衣机内筒1壁上还设有相互配合的螺钉孔，并通过螺钉相互连接，具体为，所述螺钉从洗衣机内筒1底部的圆周外侧旋入至支撑臂的端部的螺钉孔内。
本发明由于在内筒三角架与洗衣机内筒1之间设置了密封结构，使得内筒三角架与洗衣机内筒1之间的空隙被密封，切断了洗涤水进入该空隙的通道，彻底解决了洗衣机内筒1与内筒三角架之间易于存污的问题。
以上所述为本发明的实施方式，应当指出，对于本领域的普通技术人员而言，在不脱离本发明原理前提下，还可以做出多种变形和改进，这也应该视为本发明的保护范围。
