Description
本发明属于洗衣机技术领域，具体涉及一种洗衣机的上盖阻尼器、以及具有该阻尼器的洗衣机。
随着生活节奏的加快以及人们对生活舒适度的高要求，洗衣机已经成为人们日常生活中重要的家用电器。然而，在关闭洗衣机的上盖时，使用的力量过大或者上盖在关闭时受重力的影响，上盖会快速下落并且砸到洗衣机主体，从而产生巨大的声响，对洗衣机也造成了不小的损害，甚至会出现砸伤用户手指的意外，因此给用户带来了不便，影响了用户的使用感受。
现有技术中，一般通过在上盖和控制盘座之间设置弹性装置来减缓上盖的关闭速度，起到缓冲作用，但是现有的上盖阻尼无法很好的解决上盖全过程缓慢关闭的问题，使得上盖的关闭速度不能够得到有效的减缓，以及用户打开上盖需要使用很大的力；还有在下盖接近关闭位置的位置，阻尼力比较小，出现下盖关闭速度突然增加的情况，容易导致上盖突然下落。
本发明针对现有技术中存在的上述问题，提供一种洗衣机的上盖阻尼器，有利于提供与上盖开闭的速度有关的摩擦阻尼力，有效阻尼上盖的快速下降，实现上盖的关闭速度的有效的减缓。
为达到上述技术目的，本发明采用以下技术方案实现：

设置在洗衣机控制盘座上的轴孔；
可随所述上盖的开闭而旋转的摩擦部，所述摩擦部与所述轴孔的内端面摩擦产生阻尼力；
当所述摩擦部的旋转速度增大时，所述摩擦部与所述轴孔的内端面摩擦产生阻尼力增大。
进一步的，在所述摩擦部包括位于轴孔内的柱状本体、以及可径向移动的位于所述柱状本体上的摩擦块；当所述摩擦部的转速增大时，所述摩擦块沿径向向外移动，使得所述摩擦块与所述轴孔的内端面之间的压力增加。
进一步的，在所述柱状本体上开设有至少在外侧面具有敞口的槽口，所述摩擦块可移动的位于所述槽口内。
进一步的，在所述槽口内有用于所述摩擦块径向向内移动的复位弹簧。
进一步的，所述柱状本体与所述轴孔的内端面之间也具有摩擦力。
进一步的，所述上盖阻尼器还包括：与洗衣机上盖固定设置的第一齿轮，所述第一齿轮的轴线与所述上盖的旋转轴线重合；
用于传递所述第一齿轮的扭矩、且实现转速增加的第二齿轮，所述摩擦部设置在所述第二齿轮上。
进一步的，所述第二齿轮的转速与第一齿轮的转速比为7～4:1。
进一步的，所述第二齿轮与所述第一齿轮啮合。
进一步的，在所述第一齿轮和第二齿轮之间设有一个或多个传递齿轮。
进一步的，在所述第二齿轮上设有与所述摩擦部连接的第二连接部，所述第二连接部为在靠近所述摩擦部的方向上直径逐渐增大的锥形结构。
进一步的，在所述第一齿轮上设有与所述上盖连接的固定部，所述固定部包括沿轴向对称设置的两个锥形的第一连接部和第三连接部，所述第一连接部与所述第一齿轮连接、且在远离所述第一齿轮的方向上直径逐渐减小。

一种洗衣机，包括箱体、设置在箱体上的控制盘座、以及铰接设置的上盖，还包括上述的上盖阻尼器。
本发明提供的洗衣机的上盖阻尼器，通过设置可随所述上盖的开闭而旋转的摩擦部，所述摩擦部与所述轴孔的内端面摩擦产生阻尼力；当所述摩擦部的旋转速度增大时，所述摩擦部与所述轴孔的内端面摩擦产生阻尼力增大。也就是设置摩擦部与所述轴孔的内端面之间的摩擦阻尼力大小，与上盖开闭的速度有关，当上盖的开闭速度较小时，阻尼力为零或者较小；当上盖在过程中在重力的作用下，下降的速度增大时，摩擦部的旋转速度也对应增加，使得所述摩擦部与所述轴孔的内端面摩擦产生阻尼力也增大；阻尼力的增加可以更加有效的阻止摩擦部的旋转，进而阻尼上盖的下降速度，可以有效阻尼上盖的快速下降，实现上盖的关闭速度的有效的减缓。

参阅图1-图6，是本发明所提出的洗衣机的上盖阻尼器的一个实施例，一种洗衣机的上盖阻尼器，设置在所述洗衣机的上盖和控制盘座之间，设置上盖阻尼器的摩擦阻尼力的大小与上盖开闭的速度相关。
参见图1和图2所示，上盖阻尼器包括：设置在洗衣机控制盘座上的轴孔1；可随上盖2的开闭而旋转的摩擦部3，摩擦部3与轴孔1的内端面摩擦产生阻尼力；当摩擦部3的旋转速度增大时，摩擦部3与轴孔1的内端面摩擦产生阻尼力增大。也就是设置摩擦部3与轴孔1的内端面之间的摩擦阻尼力大小，与上盖2开闭的速度有关，当上盖2的开闭速度较小时，阻尼力为零或者较小；当上盖2在过程中在重力的作用下，下降的速度增大时，摩擦部3的旋转速度也增加，使得摩擦部3与轴孔1的内端面摩擦产生阻尼力也增大；阻尼力的增加可以更加有效的阻止摩擦部3的旋转，进而阻尼上盖2的下降速度，可以有效阻尼上盖2的快速下降，实现上盖2的关闭速度的有效的减缓。
参见图3和图6所示，摩擦部3包括位于轴孔内的柱状本体31、以及可径向移动的位于柱状本体31上的摩擦块32；当摩擦部3的转速增大时，摩擦块32具有沿径向向外移动的移动趋势，使得摩擦块32与轴孔1的内端面之间的压力增加。当摩擦部3的转速增大时，摩擦块32受到的离心力增加，使得摩擦块32具有沿径向向外移动的趋势，使得摩擦块32与轴孔1的内端面之间的压力增加，使得摩擦力增加。
对于摩擦块32在柱状本体31的设置，在柱状本体31上开设有至少在外侧面具有敞口的槽口，摩擦块32可移动的位于槽口内；摩擦块32的外端面为与轴孔1的内端面相匹配的弧形端面，摩擦块32在初始位置可以设置为与轴孔1的内端面接触、或者设置为与轴孔1的内端面不接触，使得摩擦块32在径向向外移动后与轴孔1的内端面接触，并且随着摩擦块32旋转速度的增加，摩擦块32受到的离心力增加，使得摩擦块32与轴孔1的内端面之间的压力增加。为了便于摩擦块32的复位，可以在槽口内有用于摩擦块32径向向内移动的复位弹簧。当设置在摩擦块32在初始位置与轴孔1的内端面接触，摩擦块32与轴孔1的内端面之间的摩擦阻尼力与摩擦部3的速度呈正比，也与上盖2开闭的速度成正比。
本实施例中，设置柱状本体31与轴孔1的内端面之间没有摩擦力，摩擦部3的摩擦阻尼力为摩擦块32与轴孔1的内端面之间摩擦提供的。
其他实施中，也可以设置柱状本体31与轴孔1的内端面之间具有摩擦力。
参见图3和图5所示，由于上盖2开闭时，开启角度一般在0°～75°之间，也就是上盖2绕轴线旋转的速度较慢；为了提供足以阻止上盖2快速下落的阻尼力，优选设置将上盖2旋转的速度放大后传递到摩擦块32上。具体的，上盖阻尼器还包括：与洗衣机上盖2固定设置的第一齿轮4，第一齿轮4的轴线与上盖2的旋转轴线重合；用于传递第一齿轮4的扭矩、且实现转速增加的第二齿轮5，摩擦部3设置在第二齿轮5上。通过设置第一齿轮4与上盖2固定，并且第一齿轮4的轴线与上盖2的旋转轴线重合；使得第一齿轮4与上盖2同步旋转，并通过设置第二齿轮5，用于传递第一齿轮4的扭矩，并且将第一齿轮4的转速放大，使得第二齿轮5的转速增加，并通设置摩擦部3设置在第二齿轮5，也就是摩擦部3与第二齿轮5同步旋转。
优选设置，第二齿轮5的转速与第一齿轮4的转速比为7～4:1，设置第二齿轮5与第一齿轮4直接啮合，通过第一齿轮4的齿数较多、直径较大，第二齿轮5的齿数较少、直径较小，实现传动比的变化，使得转速的变化。
在其他实施例中，也可以在第一齿轮4和第二齿轮5之间设有一个或多个传递齿轮，实现对于转速增加的需求。
参见图4和图5所示，为了实现连接的稳定性和牢固性，在第二齿轮5上设有与摩擦部3连接的第二连接部6，第二连接部6为在靠近摩擦部3的方向上直径逐渐增大的锥形结构，摩擦部3的柱状本体31为沿第二连接部6远离第二齿轮5的端面轴向延伸形成的。第二齿轮5的直径较小，通过设置第二连接部6为锥形结构，使得摩擦部3的直径增加，增加有利于结构的稳定。
参见图6所示，对于第一齿轮4与上盖2之间的连接固定，在第一齿轮4上设有与上盖2连接的固定部7，固定部7包括沿轴向对称设置的两个锥形的第一连接部71和第三连接部72，第一连接部71与第一齿轮4连接、且在远离第一齿轮41的方向上直径逐渐减小。通过设置固定部7实现第一齿轮4与上盖2之间的连接固定。
优选设置，在第一连接部71和第二连接部72之间设有柱形的第四连接部73，用于增加第一连接部71和第三连接部72之间的连接固定。第四连接部73的直径小于第二齿轮5的直径。在第三连接部72远离第一齿轮4的一端设有用于与上盖2固定的安装部75。
以上所述，仅是本发明的较佳实施例而已，并非是对本发明作其它形式的限制，任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或改型为等同变化的等效实施例。但是凡是未脱离本发明技术方案内容，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、等同变化与改型，仍属于本发明技术方案的保护范围。
