Description

具有可变阻尼功能的洗衣机吊杆组件及其洗衣机 技术领域
本发明涉及洗衣机技术领域，尤其是涉及一种具有可变阻尼功能的洗衣机吊杆组件及其洗衣机。
背景技术
洗衣机以及类似机械在工作过程中，由于洗涤物品的偏载及离心力作用，都会产生共振，如果不能很好地消除共振将会使机械产生跳动而无法正常工作，因此洗衣机内必须安装减振组件，减振组件的一端吊装在洗衣机箱体上，另一端悬挂在洗衣机外桶的悬挂座上，外桶的四周分别设有相应的减振组件；目前减振组件一般分为两种，一种是纯摩擦阻尼式减振组件，另外一种是摩擦和空气阻尼并用减振组件，在现有技术中，以上两种均为阻尼系数恒定不变的减振组件，在洗衣机进行脱水时，由于外桶四周的减振组件阻尼系数总是恒定不变，内桶会发生离心偏离现象，造成桶体剧烈晃动，甚至造成桶体与箱体之间产生撞击，进而产生刺耳的噪音；而且由于减振组件的恒定阻尼系数不会在极短时间内减弱离心力，因为桶体在一段时间会在持续晃动，自适应能力差。
发明内容

作为一种优选的技术方案，所述第一滑动座包括设置为一体的第一端面部和中空的第一柱体，所述第一柱体的下部设有若干用于夹紧所述弹性阻尼套的弹性夹紧片，若干所述弹性夹紧片设置于所述第一端面部的下方且均沿所述第一柱体的轴心均布设置，每两所述弹性夹紧片之间均设有一用于容纳弹性臂自由端按压部的弹性臂自由端按压部容纳间隙，若干所述弹性夹紧片之间形成一个圆柱形空腔，所述圆柱形空腔内安装有所述弹性阻尼套，每一所述弹性夹紧片的内表面均与所述弹性阻尼套相抵。
作为一种优选的技术方案，所述第二滑动座包括设置为一体的第二端面部和中空的第二柱体，所述第二柱体内设有与所述弹性夹紧片适配的压缩空腔，所述第二柱体的外周面上均布设有若干沿所述第二柱体轴向延伸的竖直导向间 隙，所述第二端面部均布设有若干水平导向间隙，每一所述水平导向间隙沿所述第二端面部轴心的径向延伸，所述竖直导向间隙与水平导向间隙连通，所述第二柱体的外周面上部均布安装有若干弹性臂，每一所述弹性臂的另一端均为用于按压所述弹性阻尼套的弹性臂自由端，每一所述弹性臂自由端的上部外侧为弹性臂自由端导向部，每一所述弹性臂自由端的下部外侧为弹性臂自由端施力部，每一所述弹性臂自由端施力部均与所述复位弹簧相抵，每一所述弹性臂自由端导向部和弹性臂自由端施力部均设置于对应的所述竖直导向间隙与水平导向间隙内。
作为一种优选的技术方案，所述弹性臂自由端施力部具有倾斜凸楞，所有弹性臂自由端施力部形成一锥形受力面，当洗衣机桶体晃动时，在所述复位弹簧的作用下，所述弹性臂自由端施力部共同按压所述弹性阻尼套。
作为一种优选的技术方案，所述第一端面部为锥形筒状结构，所述第一端面部与第一柱体之间设有若干加强筋。
作为一种优选的技术方案，所述第二滑动座与复位弹簧之间设有均匀受力垫片。
作为一种优选的技术方案，所述均匀受力垫片设有与所述弹性臂自由端施力部数量相对应的倾斜按压凹槽。
作为一种优选的技术方案，所述弹性阻尼套为聚氨酯材料制成的弹性阻尼套。

本发明的另一种技术方案是这样实现的：一种采用上述具有可变阻尼功能的洗衣机吊杆组件的洗衣机。
采用了上述技术方案，本发明的有益效果为：由于本发明应的弹簧上托组件包括：弹性阻尼套、第一滑动座和第二滑动座，当洗衣机桶体脱水晃动时，在复位弹簧的弹力作用下，第一滑动座给弹性阻尼套施加第一次夹紧力，同时第二滑动座给弹性阻尼套施加第二次夹紧力，从而可根据脱水负载的大小，通过两次夹紧力的作用使阻尼系数进行自适应调节，可在极短时间内减弱离心力，保持内桶不发现偏离或仅产生极小的偏离，避免桶体发生晃动以及桶体与箱体之间的撞击，从而大大降低了脱水时的噪音，通过这种自适应的可变阻尼功能，使洗衣机能够安静稳定的脱水，从而克服了行业内无法解决脱水噪音的技术难题。
由于第一滑动座的第一柱体下部设有弹性夹紧片，用于夹紧弹性阻尼套，在复位弹簧的轴向弹力作用下，所有弹性夹紧片向第一滑动座第二柱体的压缩空腔内移动，压缩空腔同时压缩所有弹性夹紧片，使弹性阻尼套受到各个方向均匀的夹紧力而发生变形，从而增大弹性阻尼套与吊杆的摩擦阻尼系数，减小桶体晃动。
由于第二滑动座的第二柱体具有连通的竖直导向间隙与水平导向间隙，第二柱体的外周面上部均布安装有若干弹性臂，每一弹性臂的另一端均为弹性臂自由端，所有的弹性臂自由端施力部在复位弹簧的轴向弹力作用下，使所有弹性臂自由端通过竖直导向间隙与水平导向间隙对弹性阻尼套进行按压，使弹性阻尼套受到各个方向均匀的按压力而发生变形，从而增大弹性阻尼套与吊杆的摩擦阻尼系数，减小桶体晃动。

实施例二
一种洗衣机，采用实施例一的具有可变阻尼功能的洗衣机吊杆组件。
综上所述，本发明的弹簧上托组件4包括弹性阻尼套5、第一滑动座6和第二滑动座7，当洗衣机桶体脱水晃动时，在复位弹簧8的弹力作用下，第一滑动座6给弹性阻尼套5施加第一次夹紧力，同时第二滑动座7给弹性阻尼套5施 加第二次夹紧力，从而可根据脱水负载的大小，通过两次夹紧力的作用使阻尼系数进行自适应调节，可在极短时间内减弱离心力，保持内桶不发现偏离或仅产生极小的偏离，避免桶体发生晃动以及桶体与箱体之间的撞击，从而大大降低了脱水时的噪音，通过这种自适应的可变阻尼功能，使洗衣机能够安静稳定的脱水，从而克服了行业内无法解决脱水噪音的技术难题。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
