Description

一种洗衣机的内桶组件及洗衣机 技术领域
本发明涉及洗衣设备技术领域，尤其是一种洗衣机的内桶组件及洗衣机。
背景技术
现有的洗衣机，为了避免内外桶之间积累大量的线屑和污垢，将内桶设计为洗涤时具有独立盛放洗涤水功能的洗涤桶，并在其侧壁上设置脱水时将洗涤水排出的外置水道，实现扩容目的。同时，还在内桶内设置内置水道，实现安装线屑过滤器和/或产生涌动水流提高洗涤效率的目的。
然而，现有的内置水道/外置水道与内桶之间，大多为线接触式的安装方式，水道安装后受力面积较小，易出现由于应力集中，受力不均而导致水道变形、水道及洗涤桶强度受影响的问题。并且，在安装后内置水道/外置水道与洗涤桶的内壁/外壁之间也会产生较大的安装闪缝。在洗涤时，内桶内的洗涤水和线屑等杂质易从内置水道和桶体之间的间隙进入到内置水道内，不仅难于清理，长时间也会易滋生细菌，影响洗涤效果。在脱水时，大量的风会从外置水道/内置水道和桶体之间的间隙进入到水道内部，产生风噪，影响用户的使用体验。
有鉴于此，特提出本发明。
