Definitions

  • This invention relates to a control method for a washer/dryer for the efficient determination of the period when the dried laundry reach at the required drying level.
  • drying period is one of the important variable during the drying process. Drying period affects both the energy consumption values and the moisture amount in the dried laundry. In conventional washer/dryers, the drying period is determined by the user and drying is performed during the selected duration. Drying level of the laundry is measured to lower the energy consumption values and end the drying process when the laundry reach at the required drying level.
