具体地,振动检测控制模块包括检测单元和计算单元。检测单元固定在 洗衣机上, 用于在洗衣机运转过程中检测洗衣机的振动数据。计算单元与检 测单元和所述主控板连接, 用于计算检测单元检测到的振动数据, 并与固定 容差比较, 当振动数据超过固定容差时, 生成控制信号。主控板与阻尼装置 和电机连接,主控板响应所述计算单元生成的控制信号,调节电机的工作参 数, 以及调节阻尼装置的阻尼大小,直至计算单元比对计算的振动数据维持 在固定容差范围内。
为了方便理解, 下面以一可选的方式具体说明。减振洗衣机, 包括外筒 5、 电机 2、 阻尼装置 3、 检测单元 1、 计算单元 9以及主控板 7。 其中, 阻 尼装置 3在外筒 5与洗衣机其它固定部件之间。例如设置在外筒 5与洗衣机 箱体之间。检测单元 1用于检测洗衣机的振动数据(当然是在洗衣机运转过 程中) 。 计算单元计算上述的振动数据, 并与固定容差比较, 当振动数据超 过固定容差时, 生成控制信号。 该控制信号反馈于主控板 7, 即主控板 7响 应计算单元生成的控制信号,相应的调节电机的工作参数, 以及调节阻尼装 置的阻尼大小, 直至计算单元比对计算的振动数据维持在固定容差范围内。 当然, 主控板是与阻尼装置和电机连接的。 同样的, 检测单元和计算单元也 是连接的, 用以传递信号数据等。
当然, 应该来理解, 上述计算单元将振动数据与固定容差比较, 从而可 以得出是否超过固定容差, 对振动数据的计算可以得之振动数据的具体值, 以及根据计算结果生成控制信号的控制内容。
本发明的减振洗衣机以及洗衣机减振方法所采用的检测单元能够检测 洗衣机运转过程中的振动数据, 计算单元比对振动数据与固定容差, 当振动 数据超过固定容差时,生成控制信号反馈于主控板,主控板根据控制信号调 节电机工作参数及阻尼装置的阻尼大小。当然根据上述的振动数据还可以计 算得到线性加速度、及时性方位角度等信息, 并得到洗衣机振动轨迹, 根据 这些信息相应的调节阻尼装置的阻尼力大小, 更有针对性的对振动调节。 因 此高效快速的降低洗衣机的振动。这里提及的线性加速度、及时性方位角度 等信息都是可以通过计算单元计算得出的,计算单元还可以根据计算得出的 这些参数相应的生成控制信号。
本领域技术人员均能认识到,上文提到的 "当然根据上述的振动数据还 可以计算得到线性加速度、及时性方位角度等信息,并得到洗衣机振动轨迹, 根据这些信息相应的调节阻尼装置的阻尼力大小, 更有针对性的对振动调 节"可理解为根据振动数据计算获得计算结果, 并将计算结果与固定容差相 比较, 以获得控制信号。 上述"线性加速度、 及时性方位角度等信息"即为 计算结果, 本领域技术人员可以理解,该计算结果还可包括振幅或者距离等 在振动测量技术领域较为常规的表征振动程度的参数。
进一步,上述的阻尼装置可以是磁流变减震器,当然这只是可选的情况, 其它可以调节阻尼大小的装置也可以用于本发明。当然优选的该阻尼大小可 调的阻尼装置为电控调节。
另外, 上述的计算单元 9可以是和检测单元 1集成为一体的结构。
上述的固定容差范围是一个预设的定值, 用于与振动数据进行比较, 确 定是否需要对如阻尼大小, 电机转速等进行调节, 以改变振动状况。 另外, 上述电机的工作参数可以包括转速和 /或频率。
通过对电机 2工作参数的调节, 配合对阻尼装置 3阻尼力大小的调节, 全面并且有针对性的减小洗衣机的振动。
上述检测单元 1 检测的振动数据是洗衣机运转过程中至少一个方向上 的振动数据, 且振动数据包括角速度和加速度, 可以理解, 这里振动数据包 括的角速度和加速度为: 至少一个方向上的角速度和 /或至少一个方向上的 加速度。 另外, 之所以说是 "至少一个方向", 是因为检测单元 1能够检测 洗衣机运转过程中围绕三个方向转动的角速度,以及能够检测洗衣机运转过 程中三个方向上的加速度。上述三个方向上的角速度和三个方向上的加速度 分别由: 检测单元 1包括的陀螺仪 12和加速度计 13检测。 BP, 陀螺仪 12 用于检测洗衣机运转过程中围绕三个方向转动的角速度, 加速度计 13用于 检测洗衣机运转过程中三个方向上的加速度。 三个方向分别为: 竖直方向, 以及互相垂直的两个水平方向。
为了帮助理解三个方向, 以洗衣机使用时, 放置的地面为水平面为例, 一个方向为垂直于地面(水平面) , 可以理解为 "上下"方向; 另外两个方 向彼此垂直, 并同时和 "上下"方向垂直, 即三个方向都彼此垂直, 另外两 个方向也可以理解为 "左右"方向和 "前后"方向。 简单来说, 就是洗衣机 放置在水平地面上,陀螺仪 12和加速度计 13分别检测该洗衣机在上下方向、 左右方向以及前后方向上的角速度和加速度,其中角速度是指围绕上述方向 转动的角速度。 当然, 这些方向都是本实施例中可选的, 并不用于限定本发 明, 其具体检测的方向等信息可以根据陀螺仪 12或加速度计 13自身而定, 也可以根据检测需要改变。但是其目的都是为了更加全面的记录洗衣机振动 数据, 以便能够更为精确的减少振动。
通过上述可以知晓, 检测单元 1包括陀螺仪 12和加速度计 13, 这二者 也可以统称为六轴融合传感器 (参见图 3) 。 并且可选的, 检测单元 1和计 算单元 9可以集成或设置在同一块固定板上,或者检测单元也可以和计算单 元为一体机构, 即检测单元 1既能检测, 又能计算, 当然这只是可选的实施 方式, 图中并未相应的示出该实施方式的情形。
另外, 由此可以更清楚的说明 "固定容差", 例如固定容差规定在某一 个方向上的加速度的 "固定容差"为 a, 而当检测单元将检测到的振动数据 发送给计算单元 9计算出该方向上的加速度大于 a, 则计算单元生成控制信 号, 反馈于主控板。固定容差也可以理解为某一项或多项振动数据的最大允 许值。 当然, 在振动数据超过固定容差的值的不同, 计算单元也会相应调整 生成的控制信号, 例如可以是, 当振动数据超过固定容差的值很大时, 生成 的控制信号作用于主控板后, 主控板需要将电机的转速降低 50%, 而当振 动数据超过定容差的值很小时, 生成的控制信号作用于主控板后, 主控板只 需要将电机的转速降低 10%。 这里的例子只是帮助理解, 其涉及降低电极 转速的具体值并不能限制本发明。 通过对着三个方向上的振动数据进行检测,能够更全面的获得洗衣机的 振动情况,可以更有针对性的通过主控板 7对阻尼装置 3及电机 2调节控制, 能够提高洗衣机减振的效率。
同时通过这些数据能够分析出洗衣机的运动轨迹(即振动的轨迹), 对 运动轨迹不同方向的振动数据进行分析(三个方向上的加速度以及围绕这三 个方向振动的角速度), 在任一方向振动数据超过固定容差范围时, 通过主 控板 7调节电机 2的转速和 /或频率、 以及相应方向阻尼装置 3的阻尼大小。 也可以理解为, 对运动轨迹上各个不同方向上(至少上述三个方向上)的振 动数据分析,在任意一个方向上的振动数据超过固定容差范围时,通过主控 板 7调节电机 2的转速和 /或频率、 以及相应方向阻尼装置 3的阻尼大小。
通过上述任意一个方向上的振动数据超过容差范围,就对洗衣机进行减 振调节, 因此洗衣机无论发生何种振动, 都能被检测到并且进行相应调节, 以高效完成减振, 提高了较小振动的速率。
除了上述的零部件, 洗衣机还包括洗衣机箱体 6, 洗衣机箱体 6上设置 控制面板, 洗衣机箱体 6下具有洗衣机底座 8, 洗衣机箱体 6与外筒通过阻 尼装置 3连接, 外筒内套设有洗衣机内筒 4, 洗衣机内筒 4由电机 2驱动。 采用电机 2作为动力源, 电机 2在工作运转时产生的振动, 变成洗衣机的振 源, 内筒在电机 2的带动下进行旋转, 由于衣物的存在, 内部会产生偏心负 载, 使内筒受到变载荷和变方向偏心, 产生振动, 同时外筒 5由于电机 2的 振动和内筒的振动带动下也会发生振动。此时连接外筒和洗衣机箱体的阻尼 装置 3通过改变阻尼力, 就可以起到减少振动的效果。上述阻尼装置 3可以 是设置在波轮洗衣机的外筒周向,连接外筒与洗衣机箱体 6的周壁。这里的 周壁可选的是指与底座 8连接的壁面, 该壁面在外筒的周向上包围外筒。
另一方面, 本发明还提供一种洗衣机减振方法, 包括: 设定洗衣机振动 的固定容差; 检测洗衣机的振动数据; 计算振动数据, 并与固定容差比较, 在检测到的振动数据超过固定容差时,调节电机的工作参数, 以及调节阻尼 装置的阻尼大小,直至将后续检测到的振动数据维持在固定容差范围内。为 了方便理解, 参见图 4, 可以将上述方法描述为: 步骤一, 设定洗衣机振动 的固定容差; 步骤二, 检测洗衣机的振动数据; 步骤三, 计算振动数据, 并 将振动数据与固定容差比较, 当振动数据超过固定容差时, 进入步骤四; 步 骤四,调节电机工作参数,以及调节与外筒 5连接的阻尼装置 3的阻尼大小, 反复调节, 直至将后续检测到的振动数据维持在固定容差范围内。
当然洗衣机减震方法可以是相应于上述减振洗衣机的, 因此可以知晓, 上述检测洗衣机的振动数据的检测主体是检测单元;计算振动数据并与固定 容差比较的主体是计算单元; 调节电机和阻尼装置等活动的主体是主控板。
振动数据包括: 洗衣机振动时沿至少一个方向转动的角速度, 和 /或洗 衣机振动时沿至少一个方向的加速度。当然, 上述角速度和加速度都不只是 一个方向上的, 角速度为通过陀螺仪 12检测的洗衣机振动时三个不同方向 的角速度, 加速度为通过加速度计 13记录的洗衣机振动时三个不同方向的 加速度, 其中, 三个不同方向分别为: 竖直方向, 以及互相垂直的两个水平 方向。 当然, 角速度是指围绕这三个方向转动的角速度。
在本发明的洗衣机减振方法中,上述三个不同方向的角速度以及三个不 同方向的加速度中的任意一个超过固定容差, 都会进洗衣机进行调节。结合 本发明上述装置, 围绕上述三个方向转动的角速度、在上述三个方向上的加 速度中任意一个超过了固定容差,计算单元 9都会生成控制信号反馈与主控 板板, 通过调节电机工作参数、 调节阻尼大小来降低振动。
参见图 5, 总结描述上述减振的方法, 检测单元 1检测外筒 5的振动数 据, 计算单元 9计算振动数据, 并与固定容差进行比较, 当检测到的振动数 据超过固定容差时, 计算单元生成控制信号发送给主控板 7, 主控板调节阻 尼装置的阻尼力大小, 还调节电机的转速和 /或频率, 阻尼装置的阻尼力大 小的变化, 使外筒的振动有所改变, 同时因为外筒 5会在电机 2的振动和内 筒的振动带动下发生振动, 所以当电机和内筒的转速变化后, 也会作用于外 筒, 使外筒的振动变化。 在阻尼装置、 电机和内筒的共同作用下, 外筒振动 情况发生变化, 此时检测单元 1再次检测外筒的振动数据, 重复上述方法, 直至振动数据维持在固定容差范围内。
检测洗衣机运转过程中的振动数据,并根据对振动数据的计算结果通过 主控板 7对洗衣机的阻尼进行调节,这样能够更有针对性的减小或消除洗衣 机的振动。 当然根据上述的振动数据还可以计算得到线性加速度、 以及及时 性方位角度等信息, 并得到洗衣机振动轨迹, 根据这些信息相应的调节阻尼 装置 3的阻尼力大小,更有针对性的对振动调节。 因此高效快速地降低洗衣 机的振动。
本领域技术人员均能认识到,上文提到的 "当然根据上述的振动数据还 可以计算得到线性加速度、及时性方位角度等信息,并得到洗衣机振动轨迹, 根据这些信息相应的调节阻尼装置 3的阻尼力大小,更有针对性的对振动调 节"可理解为根据振动数据计算获得计算结果, 并将计算结果与固定容差相 比较,以获得控制信号,调节电机的工作参数以及调节阻尼装置的阻尼大小。 上述 "线性加速度、 及时性方位角度等信息"即为计算结果, 本领域技术人 员可以理解,该计算结果还可包括振幅或者距离等在振动测量技术领域较为 常规的表征振动程度的参数。利用振动数据加速度和角速度计算振幅的方法 是本领域技术人员所熟知的。
本领域技术人员均能认识到,本发明利用根据振动数据获得的计算结果 与固定容差比较, 当计算结果超过固定容差时,调节电机的工作参数以及调 节阻尼装置的阻尼大小,直至将根据后续检测到的振动数据计算获得的计算 结果维持在所述固定容差范围内。
本发明中洗衣机减振方法, 与上述的减振洗衣机对应, 因此在描述中不 在过多赘述。
在本实施例中, 是以波轮洗衣机为例描述的, 其中电机安装在外筒的底 部, 这里所说的底部是指波轮洗衣机放置在水平面上使用时的底部。上述的 检测单元也可以安装在外筒的筒底,以能够更加准确快速的检测出洗衣机的 振动数据。
[实施例二】
相应于实施例一,在实施例二中以滚筒洗衣机为例进行描述,参见图 2, 相比于实施例一中,设置在滚筒洗衣机上的电机 2和检测单元 1的安装位置 都相应的变化,在滚筒洗衣机中,电机 2转轴转动的轴线与波轮洗衣机不同, 电机 2虽然是安装在外筒的筒底,但是此处的筒底的方向与波轮洗衣机筒底 的方向是不同的。 简单来说, 波轮洗衣机筒底安装的电机, 其电机转轴是与 水平面垂直的, 且筒底靠近地面; 而本实施例中滚筒洗衣机的电机转轴可以 与平面平行的, 筒底靠近洗衣机的后壁。
在本实施例中的阻尼装置 3的安装位置可以相应调整,阻尼装置在重力 方向上, 还要起到支撑滚筒(至少包括洗衣机的内筒和外筒)的作用, 因此 在外筒的下面(靠近地面)的一侧需要设置阻尼装置, 与洗衣机的固定部分 连接。 这里连接部分还包括了洗衣机的底座(图 2中未示出) 。 当然, 在外 筒周向其它位置也可以设置阻尼装置, 可选的无论是哪种实施例中的洗衣 机, 阻尼装置都可以是围绕外筒的周向布置, 且可以是液压式阻尼器。在本 实施例中围绕外筒的周向布置阻尼装置, 所以阻尼装置除了连接外筒,还会 连接洗衣机的底座, 顶盖, 以及和底座、顶盖一起在外筒的周向上将外筒包 围的两个侧壁。
当然, 阻尼装置 3的布置方式并不限于以上的安装方式, 能够起到对洗 衣机减振,尤其能够对洗衣机外筒进行减振效果的安装方式都可以用于本发 明。
其它方面, 两个实施例可以是相同的。
虽然己经详细说明了本发明及其优点,但是应当理解在不超出由所附的 权利要求所限定的本发明的精神和范围的情况下可以进行各种改变、替代和 变换。 而且, 本申请的范围不仅限于说明书所描述的过程、 设备、 手段、 方 法和步骤的具体实施例。本领域内的普通技术人员从本发明的公开内容将容 易理解,根据本发明可以使用执行与在此所述相应实施例基本相同的功能或 者获得与其基本相同的结果的、 现有和将来要被开发的过程、 设备、 手段、 方法或者步骤。因此,所附的权利要求旨在在它们的范围内包括这样的过程、 设备、 手段、 方法或者步骤。
