Abstract

一种用于洗衣机的平衡块(100)和具有其的洗衣机，所述平衡块(100)内形成有多个空腔(1)，每个所述空腔(1)内设有多个阻尼颗粒(2)。

Description

用于洗衣机的平衡块和具有其的洗衣机 技术领域
本发明涉及家用电器领域，具体而言，涉及一种用于洗衣机的平衡块和具有其的洗衣机。
背景技术
相关技术中指出，洗衣机的振动和噪音是评价其性能优劣的主要指标之一，主要的振动和噪音发生在洗衣机的脱水阶段，在脱水过程中，内桶低转速运转时，会经过驱动悬挂系统的共振点，该阶段是洗衣机发生撞击和移位的主要阶段，内桶高转速运转时，随着脱水转速的上升，洗衣机的振动量会越来越大，当振动量过大时，整机振动明显，由振动产生的噪音也会明显增加。
具体地，在工作状态下，电机驱动内桶旋转，进而带动衣物转动，这些旋转的衣物不均匀的分散在内桶里，导致离心力不平衡，从而易于导致洗衣机的振动和损坏，传统的方法是在外桶上设置平衡块，以增加外桶的重量，使外桶的中心朝向轴心和中心平面的交点移动，且由于增加了外桶的重量，可以在一定程度上增加外桶的稳定性，以减少或抵消内桶旋转时产生的振动，但是，受成本和洗衣机内空间的限制，平衡块的大小及重量都是有限的，难以在保证平衡块有限的重量和大小的情况下提高减振效果。
发明内容
本发明旨在至少在一定程度上解决相关技术中的上述技术问题之一。为此，本发明提出一种用于洗衣机的平衡块，所述平衡块具有良好的减振效果，有效地降低了洗衣机的振动噪音。
本发明还提出一种具有所述平衡块的洗衣机。
为实现上述目的，根据本发明第一方面的实施例提出一种用于洗衣机的平衡块，所述平衡块内形成有多个空腔，每个所述空腔内设有多个阻尼颗粒。
根据本发明实施例的用于洗衣机的平衡块，通过在平衡块内设置多个具有阻尼颗粒的空腔，从而充分地利用了颗粒阻尼技术的阻尼减振效果，有效地消耗了洗衣机在整个脱水阶段的振动能量，降低了洗衣机的振幅，改善了洗衣机的振动噪音问题。另外，可以在传统的平衡块改动很小的情况下采用颗粒阻尼技术，从而在基本不产生附加质量的情况下有效地提高了结构的阻尼比，实现减振、降噪效果。
另外，根据本发明上述实施例的平衡块还可以具有如下附加的技术特征：
根据本发明的一个示例，每个所述阻尼颗粒为钢制颗粒。由此，可以提高减振效果。
根据本发明的一个示例，每个所述阻尼颗粒的直径为0.05mm-5mm。
根据本发明的一个示例，每个所述空腔内的所述多个阻尼颗粒的总体积为对应的所述空腔体积的70％～80％。由此，阻尼颗粒可以有效地撞击和摩擦空腔的内壁。
根据本发明的一个示例，所述多个空腔均匀地分布在所述平衡块上。
根据本发明的一个示例，每个所述空腔沿所述平衡块的宽度方向延伸。由此，方便加工。
根据本发明的一个示例，每个所述空腔为圆柱体形。
根据本发明的一个示例，所述平衡块上形成有贯穿的安装孔，所述安装孔与所述多个空腔彼此间隔开。
根据本发明第二方面的实施例提出一种洗衣机，包括外桶和根据本发明第一方面的用于洗衣机的平衡块，所述平衡块设在所述外桶上。
根据本发明实施例的洗衣机，整体性能好。
附图说明
附图说明
图1是根据本发明实施例的用于洗衣机的平衡块的示意图。
附图标记：
100：平衡块；
1：空腔；2：阻尼颗粒；3：螺纹紧固件。
具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参考图1描述根据本发明第一方面实施例的用于洗衣机的平衡块100。
如图1所示，根据本发明第一方面实施例的用于洗衣机的平衡块100，平衡块100内形成有多个空腔1，每个空腔1内设有多个阻尼颗粒2。
具体地，多个空腔1彼此间隔开地分布在平衡块100内，每个空腔1均形成为独立且密闭腔室，其中任意两个空腔1互不相通，且任意一个空腔1均不与平衡块100的外部相通，每个空腔1内均设有多个阻尼颗粒2，优选地，每个阻尼颗粒2可以形成为圆球形，且每个圆球形的阻尼颗粒2的直径优选为0.05mm-5mm。当然，本发明不限于此，阻尼颗粒2的形状、尺寸还可以根据实际要求设置，以更好地满足实际要求。
进一步地，每个空腔1内的多个阻尼颗粒2的总体积为对应的空腔1的容积的70％～80％，从而保证每个空腔1内均具有阻尼颗粒2的运动空间，使得空腔1处于非阻塞状态。由此，随着平衡块100的振动，阻尼颗粒2之间、阻尼颗粒2与空腔1的内壁之间均产生不断的非弹性碰撞与摩擦，从而可以消耗振动能量，达到减振的目的，且通过设置多个空腔1，可以整体增加颗粒与空腔1壁的摩擦，从而进一步增大阻尼减振、降噪效果。
可选地，阻尼颗粒2可以为金属颗粒或者非金属颗粒，且阻尼颗粒2的比重越大、减振效果越好，优选地，阻尼颗粒2为钢制颗粒。
根据本发明实施例的用于洗衣机的平衡块100，通过在平衡块100内设置多个具有阻尼颗粒2的空腔1，从而充分地利用颗粒阻尼技术的阻尼减振效果，有效地消耗了洗衣机在整 个脱水阶段的振动能量，降低了洗衣机的振幅，改善了洗衣机的振动噪音问题。另外，可以在传统的平衡块100改动很小的情况下采用颗粒阻尼技术，从而在基本不产生附加质量的情况下有效地提高了结构的阻尼比，实现减振、降噪效果。
在本发明的一个实施例中，每个空腔1可以沿平衡块100的宽度方向延伸，且形成为圆柱体形，例如在图1的示例中，多个空腔1均构造为圆柱体形，且多个圆柱体形空腔1的中心轴线分别平行，每个空腔1的中心轴线均与平衡块100宽度的延伸方向相同，从而可以增加平衡块100内空腔1的数量和每个空腔1内的空间，以避免阻尼颗粒在空腔1内堆积的问题，确保阻尼颗粒2可以在个空腔1内充分运动，以提高阻尼减振效果，另外，圆柱体形的空腔1可以有效地提高阻尼颗粒2的振动次数和摩擦效果，且便于加工。
在加工的过程中，可以首先采用模具加工出具有多个空槽的平衡块100，然后再在空槽内填充一定数量的阻尼颗粒2，接着采用水泥或密封胶等将空槽的敞开端密封起来。由此，被密封的空槽为空腔1，空腔1内填充的阻尼颗粒2的填充率优选为70％。
当然，本发明不限于此，空腔1的数量、形状以及尺寸还可以根据实际要求设置，以更好地满足实际要求，例如空腔1还可以构造为圆球形、椭球形以及多面体形等。优选地，多个空腔1均匀地分布在平衡块100上。由此，可以提高减振效果。
根据本发明第二方面实施例的洗衣机(图未示出)，包括外桶(图未示出)和根据本发明上述第一方面实施例的用于洗衣机的平衡块100，平衡块100设在外桶上。
例如在本发明的一个示例中，洗衣机还可以包括：机体(图未示出)和内桶(图未示出)，其中，内桶可转动地设在外桶内，外桶悬挂在机体内，平衡块100可以固定在外桶外周壁的下部，优选地，平衡块100上可以形成有多个贯穿的安装孔，多个安装孔与多个空腔1彼此间隔开，相应地，外桶的外周壁上设有连接部(图未示出)，连接部上形成有多个连接孔，连接孔与安装孔一一对应，从而可以通过多个螺纹紧固件3将多个连接孔与多个安装孔连接在一起，进而将平衡块100可以固定在外桶的外周壁上。
这样，洗衣机在脱水的过程中，内桶低速旋转时，具有阻尼颗粒2的平衡块100可以降低悬挂系统共振点处的幅值，从而提高了洗衣机的抗偏心能力，有效地改善了撞桶现象和洗衣机的移位走路问题；随着转速的上升、当内桶高速旋转时，阻尼颗粒2的运动更加剧烈，从而可以消耗外桶的振动能量，减小了洗衣机的整机振动。由此，洗衣机在整个脱水的过程中，平衡块100均可以有效地发挥减振、降噪效果，使得整机的振动较小，提高产品的抗振动、低噪音性能。其中，悬挂系统为现有技术。
根据本发明实施例的洗衣机，通过设置上述第一方面实施例的用于洗衣机的平衡块100，从而提高了洗衣机的整体性能。
