    Abstract: A dryer comprises a drying drum, a drum motor driving the drying drum to rotate, and a drying fan for making dried hot air enter into the drying drum. The drying fan comprises a volute, a fan disposed in the volute, and a drying motor driving the fan to rotate. The drum motor and the drying motor share one motor, and the motor is capable of forward and reverse rotation, and drives the drying drum and the fan to rotate forward and reversely. The amount of air flow passed by the fan is same in both cases of forward and reverse rotation. The forward and reverse rotation of the drying drum can more effectively shake the clothes in the drying drum, so that the drying efficiency is higher and the drying is more uniform.
