Description

一种洗衣机控制方法及洗衣机 技术领域
本申请涉及洗衣设备技术领域，例如涉及一种洗衣机控制方法以及采用该控制方法的洗衣机。
背景技术
洗衣机在低速运行阶段，由于内筒中负载不平衡的存在，有时会出现撞筒现象，针对这种状况，洗衣机一般采用偏心检测方法来处理。但是，偏心检测方法精度低、可靠性差，有时不能及时执行检测，出现滞后，容易引起噪声、振动、整机移位等问题。
洗衣机运行脱水程序时，一般先进行低速阶段的偏心检测，在内筒负载分布均匀，偏心值小的情况下，转速逐渐递增。但是，随着转速的升高，负载中的水份越来越少，负载在内筒的分布状态会发生不确定性的变化，容易引起噪声、振动、整机移位等。此外，除了转速升高以外，电器件、壳体等机械结构产生的共振，也会引起噪声、振动、整机移位。如果这种状态不及时进行修正，就会造成脱水阶段的强烈振动，出现噪声，甚至整机移位。
目前洗衣机高速脱水的状态下，只有在出现撞筒，或强烈振动、整机移位时，洗衣机才会进行偏心检测处理，降低洗衣机转速，重新分布负载，再次进行偏心检测，重新开始高速运行。但是对于一般不可控的小振动，程序中却没有进行偏心检测处理，直接忽略(因为高转速下，偏心检测已经不再准确)。如果外筒和壳体之间的间隙减小，这种小的振动极有可能也会引起外筒撞击箱体，造成洗衣机出现噪声、整机振动、移位等。常见的程序处理方法为只在电机转速降低后进行偏心检测处理，这种方法显然不能满足要求。
目前有一些洗衣机采用三维位移式振动传感器，通过霍尔效应检测振动的位移量，但是位移式振动传感器有时会出现检测迟滞以及撞筒现象，整机振动、移位已经发生了，位移式传感器的数据才反馈过去，测出的数据对振动控制起不到作用。
针对上述问题，亟需提供一种新的洗衣机控制方法，以解决洗衣机存在的 高速脱水阶段下噪声大、整机振动大、易产生撞筒等问题。

在步骤D1中，洗衣机进行负载重新分布后可以跳转至步骤B1。
当洗衣机进行负载重新分布的次数和/或累计时间超过预设值后，洗衣机可以报警。
所述控制方法可以包括如下步骤：
步骤A2、洗衣机运行洗涤/漂洗程序，并开始计时；

本发明的实施方式
下面结合附图并通过实施例来说明本发明的技术方案。
本发明实施例提供了一种洗衣机控制方法，该洗衣机具有主控板以及被配置为检测外筒振动的加速度传感器，至少在高速脱水阶段，主控板根据加速度传感器检测到的外筒振动数据判断是否进行负载重新分布，并发出指令。加速度传感器能够更加灵敏的反应出外筒的振动情况，将很多不可控的振动、移位提前执行遏制，提高洗衣机的运行可靠性，避免了撞筒现象的产生，提高了洗衣效率以及洗衣机的使用寿命。
实施例一：
本实施例提供了一种滚筒洗衣机及其控制方法。该滚筒洗衣机包括主控板以及与主控板连接的被配置为检测外筒振动的加速度传感器，加速度传感器的设置位置以能有效检测外筒的振动为要求，考虑安装方便性和走线的方便性，如图1所示，本实施例中将加速度传感器2设置于外筒1的外周壁上且位于外筒1的前部，可跟随外筒1一起振动。另外，加速度传感器2不得接触洗衣机箱体以及洗衣机的其他部件。
加速度传感器2可向主控板输出外筒在相互垂直的X轴、Y轴、Z轴三个方向的振动数据，于本实施例中，水平的左右方向为Y轴，上下方向为X轴，水平的前后方向为Z轴。
由于当洗衣机运行脱水程序时，在高速脱水阶段偏心检测已经不再准确，此时主控板根据加速度传感器2检测到的外筒振动数据判断是否进行负载重新分布，并发出指令。而在低速运行阶段，单独采用偏心检测方法和单独采用加速度传感器检测方法得出的结果是十分相近的，但是，采用加速度传感器2可以实时的获取振动数据并反馈到主控板，因此对振动的检测更加准确，在低速运行阶段可以采用二者相结合的控制方法。
如图2所示，该洗衣机的控制方法包括如下步骤：
步骤A1、洗衣机执行脱水程序，进入低速运行阶段；
步骤B1、主控板判断采用偏心检测方法检测的外筒1的偏心值是否高于预设偏心值，若高于，则执行步骤D；若不高于，执行步骤C；
步骤C1、主控板内预存有振动数据与振动等级的对照数据表以及等级预设阈值，主控板根据接收的加速度传感器2检测到的X轴、Y轴、Z轴三个方向的振动数据判断外筒1的当前振动等级，并判断当前振动等级是否高于等级预设阈值，若高于，则执行步骤D1；若不高于，执行步骤E1；
步骤D1、洗衣机进行负载重新分布，然后转至步骤B1；
步骤E1、洗衣机进入高速脱水阶段，执行高速脱水，并开始计时；
步骤F1、判断计时时间是否达到或超过脱水预设时间，若达到或超过，则脱水结束；若未达到或未超过，执行步骤G1；
步骤G1、主控板根据加速度传感器2检测到的X轴、Y轴、Z轴三个方向的振动数据获得外筒1的当前振动等级，并判断当前振动等级是否高于等级预设阈值，若高于，则进行负载重新分布后转至步骤F1；若不高于，直接转至步骤F1。
步骤C中根据接收的X轴、Y轴、Z轴三个方向的振动数据判断外筒1的当前振动等级的方法不限，可以取三个方向振动数据的最大值并查询对照数据表，也可以取三个方向振动数据的平均值并查询对照数据表，还可以将三个方向向量求和后的模值作为振动数据查询对照数据表等等。
使用本实施例中的控制方法，当滚筒洗衣机外筒1和壳体之间的间隙变小的情况下，对整机出现的各种噪声、整机振动、移位实现更好的控制。一旦出现振动、噪声、移位，安装在外筒1前部的加速度传感器2就可以检测到外筒1 的振动情况，输出相应的信号给主控板，主控板对所接收的信号进行判断并提前进行相应的处理，避免洗衣机出现噪声、整机振动、移位等。
当洗衣机进行负载重新分布的次数和/或累计时间超过预设值后，洗衣机可以报警，例如，如图3所示，包括如下步骤：
步骤A1、洗衣机执行脱水程序，进入低速运行阶段；
步骤b1、判断重新分布负载的次数是否大于N，若大于N，则报警；若不大于N，执行步骤b2；
步骤b2、判断重新分布负载的累积时间是否大于T，若大于T，则报警；若不大于T，执行步骤B1；
步骤B1、主控板判断采用偏心检测方法检测的外筒1的偏心值是否高于预设偏心值，若高于，则执行步骤D1；若不高于，执行步骤C1；
步骤C1、主控板内预存有外筒振动数据与振动等级的对应对照表以及等级预设阈值，主控板根据接收的X轴、Y轴、Z轴三个方向的振动数据判断外筒1的当前振动等级，并判断当前振动等级是否高于等级预设阈值，若高于，则执行步骤D1；若不高于，执行步骤E1；
步骤D1、洗衣机进行负载重新分布，然后转至步骤B1；
步骤E1、洗衣机进入高速脱水阶段，执行高速脱水，并开始计时；
步骤F1、判断当前高速脱水时间是否达到或超过脱水预设时间，若达到或超过，则脱水结束；若未达到或未超过，执行步骤G1；
步骤G1、主控板根据加速度传感器2检测到的X轴、Y轴、Z轴三个方向的振动数据获得外筒1的当前振动等级，并判断当前振动等级是否高于等级预设阈值，若高于，则进行负载重新分布后转至步骤F1；若不高于，直接转至步骤F1。
洗衣机在洗涤/漂洗阶段也可采用偏心检测和加速度传感器检测相结合的控制方法，可以包括如下步骤：
步骤A2、洗衣机执行洗涤/漂洗程序，并开始计时；
步骤B2、判断计时时间是否达到或超过洗涤/漂洗预设时间，若达到或超过，则洗涤/漂洗结束；若未达到或未超过，执行步骤C2；
步骤C2、洗衣机判断检测到的外筒1的偏心值是否高于预设偏心值，若高于，则执行步骤E2；若不高于，执行步骤D2；
步骤D2、主控板根据加速度传感器2检测到的外筒振动数据获得外筒1当前的振动等级并判断是否高于等级预设阈值，若高于，则执行步骤E2；若不高于，直接转至步骤B2；
步骤E2、洗衣机进行负载重新分布后转至步骤B2。
实施例二：
本实施例提供了一种波轮洗衣机及其控制方法。该波轮洗衣机包括主控板以及与主控板连接的被配置为检测外筒振动的加速度传感器。加速度传感器设置于外筒的周部、底部或设置于洗衣机的吊杆上。由于当洗衣机执行脱水程序时，在高速脱水阶段偏心检测已经不再准确，此时主控板根据加速度传感器检测到的外筒振动数据判断是否进行负载重新分布，并发出指令。
本实施例波轮洗衣机的控制方法与实施例一类似，在此不再赘述。
以上结合实施例描述了本发明的技术方案。这些描述不解释为对本发明保护范围的限制。基于此处的解释，本领域的技术人员不需要付出创造性的劳动即可联想到本发明的其它实施方式，这些方式都将落入本发明的保护范围之内。
工业实用性
本申请公开了一种洗衣机控制方法及采用该控制方法的洗衣机。所述洗衣机具有主控板以及被配置为检测外筒振动的加速度传感器，至少在高速脱水阶段，所述主控板根据所述加速度传感器检测到的外筒振动数据判断是否进行负载重新分布，并发出指令。由于洗衣机在高速脱水阶段根据加速度传感器检测到的外筒振动数据判断是否进行负载重新分布，因此能够将很多不可控的振动、移位提前遏制，提高洗衣机的运行可靠性，避免了撞筒现象的产生，提高了洗衣效率以及洗衣机的使用寿命。
