本申请实施例的减振装置的应用领域不限。示例性地，本申请以减振装置应用于衣物处理设备为例进行描述。The application field of the vibration damping device of the embodiment of the present application is not limited. Exemplarily, the present application takes the application of the vibration damping device to the laundry treating apparatus as an example for description.

本申请实施例还提供一种衣物处理设备，包括洗涤筒、动力输入轴、驱动电机、以及本申请任一实施例的减振装置，动力输入轴与洗涤筒驱动连接以驱动洗涤筒转动，电机直接或间接地驱动动力输入轴转动，也就是说，电机为动力输入轴提供动力源。洗涤筒或动力输入轴的其中之一与减振装置固定连接，盘体1能够跟随洗涤筒同步转动，盘体1的转动中心O ₁位于动力输入轴的轴线上。 Embodiments of the present application further provide a laundry treatment device, including a washing tub, a power input shaft, a drive motor, and the vibration damping device of any embodiment of the present application, wherein the power input shaft is drivingly connected to the washing tub to drive the washing tub to rotate, and the motor Directly or indirectly drives the power input shaft to rotate, that is, the motor provides the power source for the power input shaft. One of the washing tub or the power input shaft is fixedly connected with the vibration damping device, the disc body 1 can rotate synchronously with the washing tub, and the rotation center O1 of the disc body ₁ is located on the axis of the power input shaft.

需要说明的是，衣物处理设备还包括外桶，洗涤筒转动地设置于外桶内，外桶对洗涤筒起安装支撑作用。具体地，动力输入轴的一端从外桶的外侧伸入外桶内并与洗涤筒连接。为了便于对动力输入轴进行转动支撑，在动力输入轴上和外桶的交界处设置有轴承和轴承座，轴承座的外缘与外桶固定连接，轴承安装在轴承座内，动力输入轴穿设在轴承中。It should be noted that the clothes treatment device further includes an outer tub, the washing tub is rotatably arranged in the outer tub, and the outer tub plays a role of mounting and supporting the washing tub. Specifically, one end of the power input shaft extends into the outer tub from the outer side of the outer tub and is connected to the washing tub. In order to facilitate the rotational support of the power input shaft, a bearing and a bearing seat are arranged at the junction of the power input shaft and the outer barrel. The outer edge of the bearing seat is fixedly connected with the outer barrel, the bearing is installed in the bearing seat, and the power input shaft passes through set in the bearing.

洗涤筒旋转为非定轴旋转，具体地，当洗涤筒不产生偏心转动时，洗涤筒的转动轴线基本与动力输入轴的轴线重合，当洗涤筒的载荷发生偏心时，洗涤筒会发生偏心转动，即洗涤筒的旋转轴线会偏离平衡位置，如此也会带动动力输入轴出现偏心转动，动力输入轴的偏心转动会通过轴承和轴承座传递给外桶，迫使外桶发生规律振动，外桶振动会造成外桶、洗涤筒以及其他零部件一起组成的整个筒部装***的振动性能变差，还会产生较大的噪声。The rotation of the washing tub is non-fixed-axis rotation. Specifically, when the washing tub does not rotate eccentrically, the rotation axis of the washing tub basically coincides with the axis of the power input shaft. When the load of the washing tub is eccentric, the washing tub will rotate eccentrically. , that is, the rotation axis of the washing tub will deviate from the equilibrium position, which will also drive the eccentric rotation of the power input shaft. It will cause the vibration performance of the entire drum-mounted system composed of the outer tub, the washing drum and other components to be deteriorated, and it will also generate larger noise.

以下以减振装置与动力输入轴固定连接为例进行描述。The following description takes the fixed connection between the vibration damping device and the power input shaft as an example.

当洗涤筒的旋转中心发生速度波动时，会带着动力输入轴和盘体也产生速度波动。请参阅图8，盘体1任一时刻的旋转中心O ₁的速度增量为ΔV _o，即旋转中心的速度出现了波动，根据刚体运动学原理，盘体1边缘任一处瞬时速度为ω*R+ΔV _oτ，其中，ω为盘体1的转动角速度，该角速度与洗涤筒的转动角速度相同，也与动力输入轴的转动角速度相同，R为盘体的半径，ΔV _oτ为ΔV _o在盘体1边缘的切线分量，ΔV _oτ会导致盘体1的边缘出现速度波动。需要说明的是，ΔV _oτ是矢量，ω*R也是矢量，当ΔV _oτ的方向与ω*R的方向相同时，ΔV _oτ的值取正数；当ΔV _oτ的方向与ω*R的方向相反时， ΔV _oτ的值取负数。盘体1的旋转中心的速度波动会导致动力输入轴的波动，因此，盘体1的旋转问题为广义的扭振问题。 When the rotation center of the washing tub fluctuates in speed, it will bring the power input shaft and the disc to produce speed fluctuations. Referring to Fig. 8, the speed increment of the rotation center O ₁ of the disk body 1 at any moment is ΔV _o , that is, the speed of the rotation center fluctuates. According to the principle of rigid body kinematics, the instantaneous speed of any edge of the disk body 1 is ω *R+ΔV _oτ , where ω is the rotational angular velocity of the disc body 1, which is the same as the rotational angular velocity of the washing tub and the rotational angular velocity of the power input shaft, R is the radius of the disc body, and ΔV _oτ is the ΔV _o at The tangent component of the edge of disk 1, ΔV _oτ , will cause velocity fluctuations at the edge of disk 1. It should be noted that ΔV _oτ is a vector, and ω*R is also a vector. When the direction of ΔV _oτ is the same as the direction of ω*R, the value of ΔV _oτ is a positive number; when the direction of ΔV _oτ is opposite to the direction of ω*R , the value of ΔV _oτ takes a negative number. The speed fluctuation of the rotation center of the disk body 1 causes the power input shaft to fluctuate. Therefore, the rotation problem of the disk body 1 is a generalized torsional vibration problem.

请参阅图6，本申请实施例中，当由于洗涤筒旋转中心的速度瞬态增大而导致动力输入轴、盘体1的中心速度瞬态增大时，摆动质量体3产生沿转动方向向后的瞬态摆角

摆动质量体3在离心力的作用下挤压弧形摆动室10沿径向外侧的弧面，摆动质量体3对弧面的挤压力F ₁，挤压力F ₁沿盘体1径向向外，需要说明的是，该挤压力F ₁为摆动质量体3以第一圆心O ₂为圆心产生的离心力。由于第一圆心O ₂与转动中心O ₁偏心，该挤压力F ₁具有在弧面的切线方向的分力F _a，分力F _a可以抑制盘体1边缘速度的增加，进而抑制盘体1的中心速度波动，从而反过来抑制动力输入轴的速度波动，达到削弱外桶的振动激励的效果，可以理解的是，当抑制了动力输入轴的速度波动时，洗涤筒的旋转中心的速度波动也得到了较好的抑制，因此，能够抑制洗涤筒的偏心转动。具体地，假设上述的挤压力F ₁所在直线与弧形摆动室10的弧面的相交点为C ₁点，直线C ₁O ₂为以第一圆心O ₂为圆心的半径所在直线，直线C ₁O ₁为以转动中心O ₁为圆心的半径所在直线，分力F _a垂直于直线C ₁O ₁。 Referring to FIG. 6 , in the embodiment of the present application, when the speed of the power input shaft and the center of the disk body 1 increases transiently due to the transient increase of the speed of the rotation center of the washing tub, the oscillating mass body 3 generates a direction of rotation along the rotation direction. Post transient swing angle

Under the action of centrifugal force, the oscillating mass body ₃ squeezes the arc surface of the arc-shaped swing chamber ₁₀ along the radially outer side. In addition, it should be noted that the pressing force F ₁ is the centrifugal force generated by the oscillating mass body 3 with the first center O ₂ as the center of the circle. Due to the eccentricity between the first circle center O ₂ and the rotation center O ₁ , the pressing force F ₁ has _a component force Fa in the tangential direction of the arc surface, and the component force _Fa can restrain the increase of the edge speed of the disc body 1, thereby restraining the disc body 1, which in turn suppresses the speed fluctuation of the power input shaft and achieves the effect of weakening the vibration excitation of the outer tub. It is understandable that when the speed fluctuation of the power input shaft is suppressed, the speed of the rotation center of the washing tub Fluctuation is also better suppressed, and therefore, the eccentric rotation of the washing tub can be suppressed. Specifically, it is assumed that the intersection point of the straight line where the above-mentioned pressing force F ₁ is located and the arc surface of the arc-shaped swing chamber 10 is point C ₁ , the straight line C ₁ O ₂ is the straight line of the radius with the first circle center O ₂ as the center of the circle, and the straight line C ₁ O ₁ is _a straight line with the radius of the circle taking the rotation center O ₁ as the center, and the component force Fa is perpendicular to the straight line C ₁ O ₁ .

摆动质量体3在离心力的作用下挤压弧形摆动室10沿径向外侧的弧面，摆动质量体3对弧面的挤压力F ₂，挤压力F ₂沿盘体1径向向外，需要说明的是，该挤压力F ₂为摆动质量体3以第一圆心O ₂为圆心产生的离心力。由于第一圆心O ₂与转动中心O ₁偏心，该挤压力F ₂具有在弧面的切线方向的分力F _b，分力F _b可以抑制盘体1边缘速度的减小，进而抑制盘体1的中心速度波动，从而反过来抑制动力输入轴的旋转中心速度波动，达到削弱外桶的振动激励的效果。具体地，假设上述的挤压力F ₂所在直线与弧形摆动室10的弧面的相交点为C ₂点，直线C ₂O ₂为以第一圆心O ₂为圆心的半径所在直线，直线C ₂O ₁为以转动中心O ₁为圆心的半径所在直线，分力F _b垂直于直线C ₂O ₁。 Referring to FIG. 7 , when the speed of the power input shaft and the center of the disc body 1 is transiently reduced due to the transient reduction of the speed of the rotation center of the disc body 1, the oscillating mass body 3 generates a transient swing angle forward in the rotational direction

Under the action of centrifugal force, the oscillating mass body ₃ squeezes the arc surface of the arc-shaped swing chamber ₁₀ along the radial direction outer side. In addition, it should be noted that the pressing force F ₂ is the centrifugal force generated by the oscillating mass body 3 with the first center O ₂ as the center of the circle. Due to the eccentricity between the first circle center O ₂ and the rotation center O ₁ , the pressing force F ₂ has _a component force F _b in the tangential direction of the arc surface. The center speed of the body 1 fluctuates, thereby suppressing the fluctuation of the rotation center speed of the power input shaft in turn, so as to achieve the effect of weakening the vibration excitation of the outer tub. Specifically, it is assumed that the intersection point of the straight line where the above-mentioned pressing force F ₂ is located and the arc surface of the arc-shaped swing chamber 10 is point C ₂ , the straight line C ₂ O ₂ is the straight line of the radius with the first circle center O ₂ as the center of the circle, and the straight line C ₂ O ₁ is a straight line with the radius of rotation center O ₁ as the center of the circle, and the component force F _b is perpendicular to the straight line C ₂ O ₁ .

由上可知，本申请实施例的减振装置为一个惯性减振***，通过分力F _a或分力F _b抑制盘体的速度波动，由于分力F _a或分力F _b沿盘体1的转动切线方向，因此能够有效地抑制盘体1的速度波动，进而抑制动力输入轴的速度波动，也就是说，即使摆动质量体12的质量较小，也能产生一定的分力F _a或分力F _b，也能起到较好的吸振效果，能以很小质量布置产生极大惯量来抵抗偏心导致的振动激励，提升振动噪音性能同时大大提高质量利用效率，可极大地降低衣物处理设备的配重质量甚至可取消大质量配重，便于衣物处理设备扩容及便于内部零部件布置。需要说明的是，由于本申请实施例的减振***并不是采用本申请背景技术中采用的平衡环的离心力来实现平衡洗涤筒的偏心质量，因此，本申请实施例的减振装置能够避免或者极大地降低本申请背景技术中的弯矩，改善动力输入轴的受力条件，提升动力输入轴的使用寿命。 It can be seen from the above that the vibration damping device of the embodiment of the present application is an inertial vibration damping system, and the speed fluctuation of the disk body is suppressed by the component force F _a _or the component force F _b _. Therefore, the speed fluctuation of the disk body 1 can be effectively suppressed, thereby suppressing the speed fluctuation of the power input shaft. That is to say, even if the mass of the oscillating mass body 12 is small, a certain component force F _a or The component force F _b can also have a good vibration absorption effect, and can generate a large inertia with a small mass arrangement to resist the vibration excitation caused by the eccentricity, improve the vibration and noise performance, and greatly improve the mass utilization efficiency, which can greatly reduce the clothes disposal. The mass of the counterweight of the equipment can even cancel the large-mass counterweight, which is convenient for the expansion of the clothes processing equipment and the arrangement of internal parts. It should be noted that, since the vibration damping system of the embodiment of the present application does not use the centrifugal force of the balance ring used in the background technology of the present application to realize the eccentric mass of the balancing washing tub, therefore, the vibration damping device of the embodiment of the present application can avoid or The bending moment in the background technology of the present application is greatly reduced, the stress condition of the power input shaft is improved, and the service life of the power input shaft is increased.
