Abstract: A laundry cleaning appliance according to the present invention includes a drum, a heater, a blower, a dryness sensor and a controller. The drum accommodates fabrics. The heater and the blower supply hot air to the drum. The dryness sensor detects the dryness of fabrics. The controller controls the temperature of the heater depending on changes in the dryness of fabrics detected by the dryness sensor. The temperature of hot air is controlled so as to be high by the heater when the dryness of fabrics is low, so that there are advantages in that the performance of drying for fabrics is improved, and the drying time of fabrics is shorten. The temperature of hot air is controlled so as to be low by the heater when the dryness of fabrics is high, so that there are advantages in that the over-dry of fabrics is prevented and, thus damages due to the over-dry of fabrics is prevented.
