WASHING MACHINE WITH VIBRATION SENSING DEVICES AND A VIBRATION SENSING METHOD, PARTICULARLY CONCERNED WITH DETECTING DIRECTLY VIBRATION DEGREE AND PHASE OF AN INNER ROTARY TUB CAUSED BY UNUNIFORM DISTRIBUTION OF THE LAUNDRY

摘要

PURPOSE: A washing machine with vibration sensing devices and a vibration sensing method are provided to directly detect the vibration of an inner rotary tub generated by eccentricity and unbalance of the laundry without an error by attaching the vibration sensing devices to an external water tube and a driving unit where vibration occurs actually. CONSTITUTION: A washing machine with vibration sensing devices(28) is composed of a housing(21) for supporting the shape of a body; a suspension(22) installed in the housing and composed of a spring and a damper; an outer water tub(23) propped up by the suspension; at least one vibration sensing device mounted at the outer water tub to detect the vibration generated by the laundry; an drum-shaped inner rotary tub(24) positioned in the outer water tub to wash the laundry; a driving unit(25) for turning the inner rotary tub; and a rotary shaft(26) for transmitting driving force of the driving unit.
