First Claim
Patent Images
1. A method for controlling the operation of a clothes dryer having a rotatable drum defining a drying chamber and an infrared temperature sensor directed toward the drying chamber, the method comprising:
- taking, with the infrared sensor, a plurality of temperature readings over time of the load of laundry in the drying chamber;
determining a temperature variation in the plurality of temperature readings; and
determining a load size estimation based on at least one of the temperature variation and a delay time wherein the delay time is a time it takes for the temperature variation to satisfy a predetermined threshold.
