Disclosed is a method for drying laundry using an intelligent washer. According to an embodiment of the present disclosure, a method for drying laundry trains a time prediction model for obtaining first remaining time information related to complete dryness of the laundry, obtains first washer state information related to a state of a washer for drying the laundry, obtains the first remaining time information by inputting the first washer state information to the trained time prediction model, and dries the washer based on the obtained first remaining time information, thus precisely predicting the time necessary for complete dryness of wet laundry. According to an embodiment, the washer may be related to artificial intelligence (AI) modules, unmanned aerial vehicles (UAVs), robots, augmented reality (AR) devices, virtual reality (VR) devices, and 5G service-related devices.
