Abstract
A method of performing a spinning operation of a washing machine is disclosed. First, a load weight of wet clothes contained in a tub is measured, and an optimal acceleration rate is calculated based upon the measured load weight. Finally, a rotational speed of the tub is gradually increased up to a predetermined speed at the calculated optimal acceleration rate such that the unbalanced distribution of the wet clothes within the tub is minimized.
Claims7
A method of controlling a spinning operation of a washing machine, the method comprising:
- measuring a first unbalanced distribution level of wet cloths contained within a tub while rotating the tub at a first speed;
- interrupting the spinning operation of the washing machine when the first unbalanced distribution level is greater than a first predetermined value;
- measuring a second unbalanced distribution level of the wet clothes while rotating the tub at a second speed selected from a resonance frequency range of the washing machine;
- and
- interrupting the spinning operation of the washing machine when a difference between the first and second unbalanced distribution levels is greater than a second predetermined value.
