Description

一种洗衣机减震装置及洗衣机 技术领域
本发明涉及洗衣机减震技术领域，具体地，涉及一种洗衣机减震装置及洗衣机。
背景技术
全自动洗衣机脱水启动和脱水运行时，外桶会随着电机启动晃动或摆动，形成较大的震动和噪音。因此，为了减弱洗衣机脱水时的震动和噪音，现有的全自动洗衣机一般都会装有减震装置，减震装置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，减震装置内设置有减震弹簧，在外桶晃动或摆动时，减震装置通过减震弹簧的缓冲作用缓解外桶的偏心，从而达到减震的目的。但是，随着洗衣机的发展进步，在洗衣机偏心较大时，如果只靠减震弹簧的减震作用，还不能有效阻止外桶的晃动和摆动。
现有洗衣机的减震装置，有的只设置有减震弹簧，多用于小容量洗衣机。有的在减震弹簧的基础上增设了滑动阻尼结构，但提供的滑动阻尼力过小，不能有效起到减震降噪效果。还有的是在滑动阻尼支撑座和上托之间增加一个摩擦橡胶件，但该结构成本高，并且可靠性不好，磨损时间长了，慢慢的就会失去摩擦阻尼力。
有鉴于此，特提出本发明。

本发明的洗衣机减震装置具有一单独设计的滑动阻尼支撑座，此结构材料使用一般的塑料材质即可，制造成本低。
本发明的滑动阻尼支撑座具有一倾斜结构，能够有效传递外桶施加的力，随着外桶的晃动或摆动，上托、滑动阻尼支撑座会沿着减震吊杆上下滑动，减震弹簧会被压缩或释放。
当外桶晃动或摆动给上托向下施加偏心力时，减震弹簧压缩，滑动阻尼支撑座收紧，和减震吊杆发生摩擦，产生阻尼力，当外桶晃动或摆动释放上托上的压力时，减震弹簧伸长，滑动阻尼支撑座松开，逐渐减小和减震吊杆之间的摩擦，减小或完全释放所产生的滑动摩擦阻尼力，减震装置的各零部件复位。
因此，本发明的洗衣机减震装置具有滑动阻尼支撑座，在洗衣机脱水启动运行时，滑动阻尼支撑座和减震吊杆之间的摩擦给外桶提供一个滑动阻尼力，有效减小外桶的晃动和摆动，起到很好的减震效果，使洗衣机保持安静稳定的脱水启动和运行。
本发明的具有上述洗衣机减震装置的洗衣机可保持安静稳定的脱水启动和运行。

具体实施方式
下面结合附图对本发明的一种洗衣机减震装置及洗衣机进行详细描述：
如图1-图5所示，本实施例的一种洗衣机减震装置，包括减震吊杆300、上托400、减震弹簧700和滑动阻尼支撑座600，所述减震吊杆300的上端端部安装在洗衣机的箱体上，上托400安装在洗衣机的外桶上，所述的减震吊杆300由上至下依次穿过上托400、滑动阻尼支撑座600和减震弹簧700；所述滑动阻尼支撑座600具有可变阻尼结构，用于在外桶晃动或摆动时传递偏心力产生作用于减震吊杆300的滑动阻尼。
优选地，本实施例的可变阻尼结构包括倾斜结构602和形变阻尼结构，倾斜结构602传递偏心力给形变阻尼结构，形变阻尼结构形变产生作用于减震吊杆的滑动阻尼。
本实施例的滑动阻尼支撑座600具有一倾斜结构602，能够有效传递外桶施加的力，随着外桶的晃动或摆动，上托400、滑动阻尼支撑座600会沿着减震吊杆300上下滑动，减震弹簧700会被压缩或释放。优选地，为了使倾斜结构602能够将外通晃动或者摆动产生的偏心力有效传递到滑动阻尼支撑座600的可形变部位，为阻尼吊杆提供滑动阻尼，以实现良好的减震效果，因此，本实施例的倾斜结构602沿着减震吊杆300由上至下的方向朝着靠近减震吊杆300的方向倾斜，使得受压时的偏心分量产生水平方向的分力作用于滑动阻尼支撑座600的可形变部位收紧产生滑动阻尼力。
当外桶晃动或摆动给上托400向下施加偏心力时，减震弹簧700压缩，滑动阻尼支撑座600收紧，和减震吊杆300发生摩擦，产生阻尼力，当外桶晃动或摆动释放上托上的压力时，减震弹簧700伸长，滑动阻尼支撑座600松开，逐渐减小和减震吊杆300之间的摩擦，减小或完全释放所产生的滑动摩擦阻尼力，减震装置的各零部件复位。
因此，本实施例的洗衣机减震装置具有滑动阻尼支撑座600，在洗衣机脱水启动运行时，滑动阻尼支撑座600和减震吊杆300之间的摩擦给外桶提供一个滑动阻尼力，有效减小外桶的晃动和摆动，起到很好的减震效果，使洗衣机保持安静稳定的脱水启动和运行。
因此，本实施例的洗衣机减震装置具有一单独设计的滑动阻尼支撑座600，即可对减震吊杆300起到良好的滑动摩擦阻尼，提升洗衣机的减震效果。本实施例的滑动阻尼支撑座600可单独使用即可满足一般洗衣机的减震要求，或者与滑动阻尼块相配合进一步增加其滑动阻尼的效果，以获取更好的减震效果，适应更大规格的洗衣机。另外，本实施例的滑动阻尼支撑座600的材料使用一般的塑料材质即可，制造成本低，且使用寿命长。
为了实现本实施例的滑动阻尼支撑座600随着外通的晃动或者摆动改变对减震吊杆300的滑动阻尼大小，具体地，本实施例所述的滑动阻尼支撑座600包括设置在一端的环形本体601和与环形本体601分别连接的多个弹性体606，所述的环形本体601与上托400相抵设置，所述的弹性体606伸入到减震弹簧700内，多个所述弹性体606之间形成位于中心用于减震吊杆300穿过的通孔：
洗衣机的外桶晃动或摆动施加偏心压力给上托400，减震弹簧700压缩，滑动阻尼支撑座600的倾斜结构602传递偏心力给各所述的弹性体606，弹性体606收紧增大对减震吊杆300的滑动阻尼；
洗衣机的外桶晃动或摆动释放上托，减震弹簧700伸长，各所述弹性体606松开减小或完全释放对减震吊杆300的滑动阻尼。
本实施例的弹性体606之间具有弹性间隙605，外通不发生晃动或者摆动时，弹性体的内壁与减震吊杆300相接触但不发生挤压摩擦或者挤压摩擦力不大，当外通发生晃动或者摆动时，弹性体606在倾斜结构602传递的偏心力作用下收紧，弹性体606的内壁与减震吊杆300紧密接触且挤压摩擦产生较大的滑动摩擦阻尼，以减缓外桶的晃动或者摆动，实现减震的效果。
优选地，本实施例的弹性体606包括四个，四个弹性体606围成一圈，弹性体606之间具有弹性间隙605。
具体地，本实施例所述的弹性体606沿着环形本体601的周向均匀间隔分布；所述的弹性体606与环形本体601相连接的一端倾斜设置形成倾斜结构602，或者所述的倾斜结构602为用于连接弹性体606与环形本体601的倾斜筋。
本实施例的倾斜结构602朝向环形本体601的中心倾斜设置，这样，滑动阻尼支撑座600整体由环形本体601至弹性体606呈缩小趋势设置。本实施例的滑动阻尼支撑座600可一体成型制成，也可由个部分相连接形成。
具体地，本实施例的形变阻尼结构为弹性体或者弹性体的竖直段。
作为本实施例的一种优选实施方式，所述弹性体606包括倾斜段和竖直段，所述倾斜段的一端与环形本体相连接，另一端朝向环形本体内侧倾斜设置，所述的竖直段与倾斜段相连且沿着竖直方向设置；所述弹性体606的竖直段的内壁向内凸出设置与减震吊杆接触，用于产生对减震吊杆的滑动阻尼。本实施例的弹性体606和倾斜结构602一体成型，弹性体606的倾斜段即为倾斜结构602，竖直段即为与减震吊杆300接触产生滑 动摩擦阻尼的形变部。
作为本实施例的一种优选实施方式，所述倾斜筋的一端与环形本体601相连接，另一端朝向环形本体601内侧倾斜设置且与弹性体606连接，所述的弹性体606沿着竖直方向设置；所述弹性体606的内壁向内凸出设置与减震吊杆300接触，用于产生对减震吊杆的滑动阻尼。本实施例的倾斜筋可与环形本体601一体成型制成，弹性体606与倾斜筋固定连接，这样，弹性体606可采用阻尼系数更高的橡胶材料制成，且可根据需要选择相应规格的弹性体606以满足滑动阻尼要求。
本实施例所述的倾斜筋包括多个，沿着环形本体601的周向与弹性体606一一对应设置。
进一步地，本实施例各个所述弹性体606的倾斜段和竖直段的相交处的外壁上分别设置挡筋604，各个挡筋604围成环形挡筋，所述减震弹簧700的上端止抵于环形挡筋；
或者，各个所述倾斜筋与各个所述弹性体606相交处的外壁上分别设置挡筋604，各个挡筋604围成环形挡筋，所述减震弹簧700的上端止抵于环形挡筋。
本实施例的滑动阻尼支撑座600设置在上托400和减震弹簧700之间，滑动阻尼支撑座600的环形本体601与上托400相抵，在上托400承受外桶的偏心力时可以直接作用于滑动阻尼支撑座600上，滑动阻尼支撑座600还具有用于止抵减震弹簧700的环形挡筋，这样，外桶的偏心力一部分可通过滑动阻尼支撑座600直接作用于减震弹簧700，减震弹簧700压缩提供减震弹力，另一部分偏心力通过倾斜结构作用于弹性体606，弹性体606与减震吊杆300摩擦产生滑动摩擦阻尼。因此，本实施例的滑动阻尼支撑座600针对洗衣机外桶的晃动和摆动具有良好的减震效果。
作为本发明的一种优选实施方式，所述的挡筋604与弹性体606的倾斜段外壁之间设置加强筋603；或者所述的挡筋604与倾斜筋的外壁之间设置加强筋603。加强筋603的设置可以增加滑动阻尼支撑座600的整体强度，具有更好的耐磨性，延长使用寿命。
作为本发明的一种优选实施方式，本实施例的洗衣机减震装置还包括减震垫500，所述的减震吊杆300依次穿过减震垫500，所述的减震垫500设置在上托400与滑动阻尼支撑座600之间。减震垫500与滑动阻尼支撑座600的配合可进一步增加洗衣机减震装置的滑动阻尼效果，具有更好的减震性。
具体地，本实施例的减震垫500为片状结构即可，制造简单，成本较低。减震垫500为采用阻尼性能较好的材料制成，例如橡胶。
本实施的洗衣机减震装置还包括固定安装在减震吊杆300上端端部的吊杆座200，所述的吊杆座200吊装在洗衣机的箱体上部。所述的吊杆座200与洗衣机的箱体之间增设垫片100，增加减震作用。
本实施例的洗衣机减震装置还包括固定安装在减震吊杆300下端端部的下托800，所述的减震弹簧700的下端止抵于所述的下托800上。
本实施例同时提供了一种具有上述任意一项所述洗衣机减震装置的洗衣机。本发明的具有上述洗衣机减震装置的洗衣机可保持安静稳定的脱水启动和运行。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
