Patent ID: 7000436

Claim:
A washing machine comprising: a rotatable laundry receptacle; a motor operatively connected to said rotatable laundry receptacle to rotate said rotatable laundry receptacle; a rotation velocity detector operatively connected to said rotatable laundry receptacle to obtain data regarding a rotation speed of said rotatable laundry receptacle; and control circuitry operatively connected to said rotation velocity detector to receive said data therefrom and operatively connected to said motor to run said motor, said control circuitry configured to make a first determination that a first deviation between said rotation speed and a first spin cycle speed is within a first predetermined range, further configured to make a second determination that a second deviation between said rotation speed and a second spin cycle speed is outside of a second predetermined range, further configured to cause said motor to accelerate from said first spin cycle speed to said second spin cycle speed in response to said first determination, and further configured to cause said motor to decelerate from said second spin cycle speed to said first spin cycle speed in response to said second determination.
