Drying control method for washer combined with dryer or dryer

Laundry dryer / drying control apparatus and method of the dryer according to the invention, after the start of the drying of the washing operation, the temperature (Tc) of the cooling water condensing the moisture contained in the air when passing through the condensing duct dry the laundry air and the flow through the condensing duct to measure the temperature (Ta) of the moisture is removed, air, temperature in the course of the drying operation duration of the washing, and the signal indicative of the temperature (Tc) characteristic of the cooling the air (Ta) by controlling the drying operation to determine the dry state of the laundry to a temperature (Td) difference signal representative of the characteristic, it is possible to control to correct accurately the drying degree than in accordance with the load conditions such as the ambient air temperature or the coolant temperature, whereby by a more efficient drying operation it can be controlled in accordance with the effect to improve the drying performance. Washing and drying machine, the tub, the drum, a cooling water temperature sensor, a condensing duct, an air temperature sensor, a cooling water valve, the heater duct, a heater
