Patent number: 8984917Abstract: A washing machine in accordance with the present invention includes a mounting member disposed between a stator and a bearing housing. Thus, when a motor is rotated according to an operation of the washing machine, the transmission of vibration, which is generated by a repulsive force of the stator, to the bearing housing can be reduced efficiently. Accordingly, a tub coupled to the bearing housing can be prevented from vibrating due to the vibration of the stator, and noise due to the vibration of the tub can be reduced.Type: GrantFiled: February 18, 2009Date of Patent: March 24, 2015Assignee: LG Electronics Inc.Inventors: Seong Hyeon Kim, Kyung Seop Hong, Jae Won Chang, Seung Chul Park
