  • Publication number: 20120017645
    Abstract: A vibration isolation system for a front-loading clothes washing machine and the like which provides isolation of intermittent or continuous vibration of a rotating basket from support feet which support the washing machine. The vibration isolation system includes a plurality of vibration isolation assemblies each including a flexible member or rod which is supported by a pair of opposing bearing supports. The vibration assemblies can be located between a cabinet enclosing the basket and the support feet, a drum generally enclosing the basket and the cabinet, or any other suitable location between the basket and the support feet. The configuration of the flexible members relative to one another and the spinning axis of the basket may vary depending upon the design of the washing machine components.
