Abstract

The present disclosure relates to an apparatus and a method of reducing vibrations in a washing machine, and particularly, to an apparatus and a method of reducing vibrations in a washing machine that may predict a resonance frequency (or vibration generation region) before operating or driving a motor during a washing process to prevent a resonance phenomenon, thereby reducing noise and vibrations in the washing machine. To this end, the apparatus may include a motor configured to transmit rotational force; a motor driving unit configured to output a motor driving signal controlling an operation of the motor; and a filter configured to remove or reject a frequency or band causing a resonance phenomenon of the washing machine and allow another frequency or band to pass through in the motor driving signal output.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Korean Patent Application No. 10-2013-0163775 filed on December 26, 2013, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to an apparatus and method for reducing vibration in a washing machine, and more particularly to an apparatus and method for reducing vibration in a washing machine that predicts the resonance preceding the motor that drives or operates the washing machine frequency or generation area, and prevents (vibration) resonance phenomena, thereby reducing noise and vibration in washing machines. Background technique [0004] Generally, a washing machine refers to a mechanical device that can quickly clean dirt in and / or on dirty clothes such as clothes or bedding by using washing liquid, friction of water flow due to rotational motion, collision with clothes, etc. [0005] Accord...
