First Claim
Patent Images
1. A laundry dryer control method comprising the steps of:
- initiating a drying procedure by driving a heater for heating air and a motor for rotating a drum;
measuring temperature by a temperature sensor;
calculating a plurality of temperature variation rates;
detecting whether there is a substantial increase in the temperature variation rate with respect to the temperature variation rate of initiating the drying procedure;
calculating a remaining drying time after the substantial increased is detected; and
performing the drying procedure for the calculated remaining drying time, wherein the drying procedure is divided by the difference of the temperature variation rate as the drying procedure proceeds.

Abstract
A laundry drier control method reads a temperature variation rate per unit time, to enable drying according to the amount and type of an object being dried. The method includes steps of initiating a drying procedure; measuring a temperature variation rate per unit time over the drying procedure; calculating an overall drying time based on the measured temperature variation rate per unit time; and performing the drying procedure for the calculated overall drying time. The drying time determining step is repeated if a substantial increase in the temperature variation rate is detected.
