Description

一种双滚筒洗衣机 技术领域
本发明属于衣物处理装置技术领域，具体地说，涉及一种双滚筒洗衣机。
背景技术
随着社会发展和人们对生活品质要求不断提高，双滚筒衣物处理装置顺应时代的发展和需求应运而生，不但可以节省衣物处理装置的放置空间，而且为用户提供更便利的衣物处理需求。
双滚筒衣物处理装置的其中一个重要的技术问题是如何设置双滚筒。以前的常规做法是将两个滚筒分别设置在各自的框架中，但是两个滚筒之间存在间隙，不仅占据了较多的空间，而且在使用过程中的震动噪音也比较大。
后来也有技术对此进行了改进，将两个滚筒连接起来，相对缩小了双滚筒衣物处理的空间，也一定程度上降低了噪音，但是仍需要在外筒上加装包括配重块的调节平衡装置，不仅增加洗衣机的成本，减震降噪效果不明显。并且连接双滚筒的元件是单独设置的，不仅安装繁琐，而且还容易受到双滚筒衣物处理的长期运行过程的震动影响而造成脱落等问题，稳定性不佳。
有鉴于此特提出本发明。
发明内容
本发明要解决的技术问题在于克服现有技术的不足，提供一种双滚筒洗衣机。所述双滚筒洗衣机的双滚筒连接近乎一体，减少辅助固定零部件的使用，双滚筒之间的连接更加牢固可靠、更加紧凑，可有效降低双滚筒洗衣机运行时的震动，减轻噪音污染，不必设置额外的配重块，降低生产成本。
为解决上述技术问题，本发明采用技术方案的基本构思如下：

优选地，所述连接部设于第二外筒上侧靠近筒底的部位，所述螺栓柱设于第一外筒下侧靠近筒底的部位。
优选地，所述凸台的中央部位设置有适于人手提握的中通结构。
优选地，包括用于连接第一外筒和第二外筒前部的前连接件，前连接件包括上部的类U型结构以及设于类U型结构下部的左、右支端，左右支端设于不同高度部位，类U型结构的两端部和左、右支端设有安装通孔，第一外筒和第二外筒前部设有一体成型的螺栓柱，螺栓柱设有中空结构，螺栓柱贯穿安装通孔，螺钉经垫片与中空结构连接固定。
优选地，所述螺栓柱周壁上设有多条沿轴向分布的凸筋，所述安装通孔设为圆柱孔。
优选地，安装通孔内设有与所述凸筋对应的凹槽。
优选地，所述曲端面上设有弹性缓冲层，所述弹性缓冲层具有与第一外筒外壁相匹配的表面结构。
所述的双滚洗衣机可以是包括两个滚筒的洗衣机或洗干一体机或干衣机等。
采用上述技术方案后，本发明与现有技术相比具有以下有益效果：

所述曲端面上设有弹性缓冲层，所述弹性缓冲层具有与第一外筒1外壁相匹配的表面结构。可以进一步降低噪音，而且还可以减轻第一外筒1与凸台之间的撞击作用，保护第一外筒1结构和连接部的结构。
采用上述技术方案后，本发明与现有技术相比具有以下有益效果：
1、所述双滚筒洗衣机的外筒一体成型有连接部，其端部与另一外筒连接，有助于使双滚筒形成近乎一体的结构，且采用的辅助固定零件少，不易在震动中造成双滚筒连接结构的松脱，更加稳固可靠；
2、所述连接部的结构自第一外筒表面向另一外筒延伸设置，可以充分地利用第一外筒和第二外筒的放置间隙，不需要占据额外的空间，令双滚筒洗衣机的结构更加紧凑，降低了震动噪音；
3、所述双滚筒洗衣机可以不设置额外的配重块，减少部件设置，不仅可以降低成本，而且部件越少、出现故障的几率越低，有助于提高整体结构的稳定性；
4、所述的双滚筒洗衣机的连接部或者连接件具有与外筒边缘相配合的曲面等结构，可以对位于其上的外筒起到承托作用，不仅减轻外筒支撑件的负担、延长其使用寿命，而且还可以减缓运行过程中因外筒位移变化显著而造成的噪音；
5、连接部的端部设置的连接外筒的安装通孔设置在不同高度，外筒连接后，利于协调双滚筒在运行中的位移变化，从而降低震动噪音。
