1. A drying method for a laundry room machine that includes a payment device that collects payment for operation of the laundry room machine for a preset dry time corresponding to a selected drying course upon receiving payment insertion information from the payment device, the drying method comprising:
- determining a condition of laundry items received in a drum of the laundry room machine by measuring a humidity level in the drum; and
when it is determined that the laundry items are dried within a first predetermined time that is less than the preset dry time, sustaining a supply of hot air to the laundry items in the drum up to a predetermined temperature and then cooling the laundry items in the drum during a remaining preset dry time;
when it is determined that the laundry items are not dried within the first predetermined time and that the laundry items are dried within a second predetermined time that is between the preset dry time and the first predetermined time, resetting a hot air supplying time and a cooling time so that a sum of the hot air supplying time and the cooling time does not exceed the remaining preset dry time; and
when it is determined that the laundry items are not dried within the first predetermined time and that the laundry items are not dried within a time difference between the preset dry time and the first predetermined time, stopping a supply of hot air to the laundry items in the drum and then cooling the laundry items in the drum during the first predetermined time.
