Description

易拆卸内桶的波轮洗衣机 技术领域
本发明涉及一种波轮洗衣机，特别是一种易拆卸内桶的波轮洗衣机。
背景技术
洗衣机的清洗桶分为内桶和外桶，内桶为带过滤网和过滤孔的圆柱桶，外桶为光面塑料桶。经长时间的使用，洗衣机的内桶和外桶上会粘接各种杂质颗粒，衣服上的大量污物和细菌会残留内桶和外桶上。目前，对洗衣机的清洗一般采用清洗液，将洗衣机的内桶放满水，将清洗液倒入水中，经过长时间浸泡，通过清洗液的化学性能，将桶上的一些杂质溶解，然后再经过反复的放水进行冲洗，达到清洗洗衣机的目的。这种清洗方式不仅要浪费大量的水，而且费时费力，洗衣机放置一段时间后，由于内外桶潮湿，会产生很大的霉气味，细菌滋生也十分严重，不受消费者的认可和推广。还有的洗衣机的内桶能够拆卸，通过将内桶拆卸下来对其内外进行单独清洗，达到清洁的目的，但是使用者一般为普通大众，现有的内桶可拆卸洗衣机的拆卸过程比较繁琐，使用者很难单独操作，因此也不能被广大消费者和使用者认可。
发明内容
本发明是针对背景技术中所存在的技术缺陷，提供一种能够实现快速拆卸、易清洗的波轮洗衣机。
本发明采用的技术方案是：一种易拆卸内桶的波轮洗衣机，包括洗衣机内桶，洗衣机内桶中心孔中插装有内桶传动轴，内桶传动轴内部同心套装有一波轮轴，该内桶传动轴的下端与洗衣机的驱动机构连接，波轮通过波轮轴套安装在波轮轴的上部，还包括卡接机构；波轮底面设置有一与其同心的凸缘结构，
所述的内桶传动轴上套装有周向定位盘，内桶底部设置有周向定位槽，周向定位盘和周向定位槽相匹配；
所述卡接机构设置在波轮轴套和波轮轴的结合位置，该卡接机构为按压式结构，通过卡接件将波轮轴套固定在波轮轴上。
所述的卡接机构为弹簧卡块式，卡接件为卡块，卡块为带孔的块体，波轮轴上部沿其圆周设置有环形限位槽，卡块套设在限位槽上，卡块上固接有压簧。
卡块的厚度小于限位槽宽度。
波轮轴的限位槽内上下并列设置有两组卡接机构，二者对称设置。
所述的卡接机构为按压顶杆式，卡接件为拨杆，波轮轴上部沿其圆周设置有一环形限位槽，拨杆置于限位槽内，波轮轴套上设置有滑孔，按块置于滑孔内，按块与拨杆的自由端触接。
滑孔内壁和按块端部分别设置有相匹配的卡头。
按块与滑孔之间为滑动配合。
拨杆自由端为向外侧弯曲的圆弧状结构。
所述的周向定位盘和周向定位槽为相互匹配的任意几何形状。
内桶底的厚度≥内桶中心孔直径。
与现有技术相比，本发明结构简单，拆装方便，便于清洗，普通消费者就能通过按压的方式，将洗衣机内桶轻松取出，并对内桶和外桶进行单独的清洗，以达到对其消毒、清污的目的。

具体实施方式
下面结合附图和实施例对本发明做进一步说明。
参见附图1-6，本发明所公开的这种易拆卸内桶的波轮洗衣机， 包括内桶1，波轮2，波轮轴3，卡块4，波轮轴套5，周向定位盘6，周向定位槽7，压簧8，环形限位槽9，按块10，滑孔11，拨杆12，转轴13。洗衣机内桶的中央设置有一内桶中心孔，内桶中心孔中插装有内桶传动轴，内桶传动轴内部同心套装有一波轮轴，该内桶传动轴的下端与洗衣机的驱动机构连接，波轮通过波轮轴套安装在波轮轴的上部，波轮通过卡接机构限位固定在波轮轴上。波轮与内桶底面为间隙配合。波轮底面有一与其同心设置的凸缘，凸缘外径大于波轮轴套内径。凸缘高度根据实际使用时波轮大小设定。
内桶传动轴中部套装有周向定位盘，内桶底部设置有周向定位槽，周向定位盘和周向定位槽相匹配。周向定位盘和周向定位槽为相互匹配的任意几何形状，本实施例中，如附图2所示，周向定位盘和周向定位槽为锯齿形结构，其也可以为六边形、四边形或其他能够起到周向定位作用的匹配结构。
波轮轴上部为花键轴，波轮轴套内壁为键槽，波轮通过波轮轴套套装固定在波轮轴上。在实际设计中，波轮轴套与内桶底部为间隙配合，为避免波轮轴套与内桶底部过度摩擦，在波轮底部设置凸缘，该凸缘为圆弧面，其能有效减少波轮底面与内桶底面的摩擦。波轮轴套底部凸缘底面到内桶上底面的距离小于周向定位盘的厚度。通过卡接机构中的卡接件起到对波轮轴套的轴向限位作用。该卡接机构为按压式结构，通过卡接件将波轮和内桶固定在波轮轴上。一般情况下，环形限位槽内上下并列设置两个对称的卡接机构。
内桶底的厚度大于等于内桶中心孔直径，这种结构能够保证内桶在运转过程中的稳定性。
实施例一：卡接机构为弹簧卡块式，卡接件为卡块，波轮轴上部沿其圆周设置有一环形限位槽，卡块为一端带孔的块体，卡块上的孔套装在波轮轴的环形限位槽内，卡块外壁与波轮轴套内壁之间固接有压簧。卡块的厚度小于限位槽宽度。压簧放松状态下，卡块的孔壁被顶接在环形限位槽槽底上，卡块对波轮轴套起到轴向限位作用；需要拆卸时，用手按压突出的卡块，卡块上的孔脱离限位槽，接触卡块对传动轴的卡接限定，波轮轴套和内桶被取出。
实施例二：卡接机构为按压推杆式，卡接件为拨杆，波轮轴上部沿其外圆周设置有一环形限位槽，拨杆置于限位槽内，波轮轴套上设置有滑孔，按块置于滑孔内，按块与拨杆的自由端触接。滑孔内壁和按块端部分别设置有相匹配的卡头，能够有效防止按块滑出，卡头可设计成矩形、三角形等各种形状。按块与滑孔之间为滑动配合。拨杆自由端为向外侧弯曲的圆弧状结构，按块自由端为斜面，按块自由端顶触拨杆自由端，沿着斜面，拨杆被顶出，脱离限位槽。拨杆与转轴连接端装有回位弹簧。在常态下，拨杆在回位弹簧的作用下置于限位槽内，对波轮轴套起到轴向限定作用。在需要拆卸时，按压按块，顶杆被推出，拨杆被推离限位槽，拨杆对内桶传动轴的限位作用取消，波轮和内桶被取出。
