Abstract (en)
[origin: EP1657351A2] A drying control method for washing machines with drying functions/drying machines comprises an air temperature-measuring step of heating air passing through a heater duct (110) by means of a heater (103) during a drying operation of the washing machine with drying function or the drying machine, and measuring at least one of the temperature (Tin) of air before being heated and the temperature (Tout) of air after being heated about the heater (103), a load-calculating step of calculating total load, the sum of the amount of laundry and moisture content contained in the laundry, using a ratio of the change in temperature to the change in time at a specific section while the temperature (Tin or Tout) of the air is measured at the air temperature-measuring step, a moisture content-calculating step of calculating the moisture content contained in the laundry using a ratio of the change in temperature to the change in time at another specific section next to the specific section of the load-calculating step, and a drying operation-controlling step of controlling the drying operation of the washing machine with drying function or the drying machine according to the total load and the moisture content calculated at the load-calculating step and moisture content-calculating step. According to the drying control method, it is possible to more accurately estimate drying time using moisture content contained in the laundry and more efficiently control the drying operation corresponding to various load conditions.
