Vibration absorbing mechanism for washing machine and washing machine

Abstract

A vibration absorbing mechanism for a washing machine and a washing machine having the same are provided. The vibration absorbing mechanism includes a plurality of first vibration absorbers for supporting an outer drum of the washing machine. A second vibration absorber is connected between at least two of the first vibration absorbers. Based on the existing first vibration absorbers, the second vibration absorber connected with two first vibration absorbers is additionally provided on the vibration absorbing mechanism. Through the second vibration absorber, an amplitude of the outer drum of the washing machine is inhibited to effectively limit vibration in up-down direction and left-right direction of entire washing machine. Therefore, the volume of a counterweight is effectively reduced, so that the structure of the washing machine is more compact while achieving better vibration absorbing and noise reduction effects.
