Abstract
A vibration control device for a washing machine is composed of a drum to house laundry, a washing tank to house the drum which is suspended by a chassis of the washing machine, a drum driving motor, an acceleration detecting unit to detect an acceleration in the horizontal direction of the washing tank, a linear actuator fixed to the chassis of the washing machine to generate a driving force in the horizontal direction to the chassis of the washing machine, a force transmitting unit to connect a movable axis of the linear actuator with the washing tank, and a control unit to control the driving force of the linear actuator based on the acceleration detected by the acceleration detecting unit. The force transmitting unit transmits the driving force and absorbs mechanistically relative displacement in the back and forth direction and in the up and down direction.
