The invention relates to a method of treating clothes, which adopts a washing machine to execute a clothes dewatering program and a clothes drying program. The washing machine comprises an outer drum, a barrel and a blower device, wherein the barrel comprises a plurality of through holes distributed on the barrel wall. An auxiliary program is executed between the dewatering program and the clothes drying program and comprises a step that the blower device is started to blow an air flow into the outer drum and further blow air flows into barrel by the through holes of the barrel. An electric appliance of treating clothes comprises a control device which can execute the auxiliary program according to program setting and starts the blower device to blow the air flows into the outer drum and the barrel in the auxiliary program. The high-speed air flows blown by the blower device into the outer drum and the barrel can blow off and scatter the clothes which are tightly attached to the innerwall of the barrel due to the high-speed rotation of the barrel so as to lighten clothes folds and deformation generated by attaching to the inner wall of the barrel.
