The clothes dryer is a clean household appliance which utilizes heated air to evaporate and dry moisture in washed clothes in time, and is popular among people due to the characteristic of quick clothes drying. Along with the increasing market demand of the clothes dryer, the requirement on the drying effect of clothes is also higher and higher, the problem of clothes winding of the clothes dryer in the operation process is always the focus of attention, and the winding not only can increase the wear degree of the clothes, but also can influence the drying effect of the clothes, so that the clothes are not dried or excessively dried.
Generally, a clothes dryer includes a drying drum, a drum motor for driving the drying drum to rotate, and a fan for supplying drying air to the drying drum. The clothes drying equipment is provided with a driving device to drive the drying roller to rotate and stir clothes in the drying roller; and the fan is driven to rotate, airflow is formed in the air channel formed by the air channel and the drying roller, and the clothes in the drying roller are dried by the airflow.

Therefore, on the premise of considering the safety and the clothes drying efficiency of the heating element of the clothes dryer, the clothes dryer rotates the drying drum in one direction most of the time in the whole drying process, and the clothes in the drying drum roll in one direction for a long time and are easy to be wound and knotted, particularly the phenomenon of winding and knotting is serious when large articles such as bed sheets, quilt covers and curtains with large volume are dried, and the inside of the knotted clothes has the problem of incomplete drying, which brings great trouble to users.
The other scheme of the clothes dryer is as follows: the drum motor is provided with two output ends which respectively drive the drying drum and the fan to rotate so as to enable the drying drum and the fan to synchronously rotate; the fan blades of the fan are designed into a straight tooth shape, so that the fan can rotate towards two directions and wind is provided, but the wind in each direction is not large. Although the dryer that adopts above-mentioned traveling can realize the effect of drying the positive and negative two-way rotation of cylinder in the stoving, because the amount of wind is less in the fan rotation process for the efficiency of stoving reduces, and the stoving time lengthens, influences user's experience.
The invention aims to solve the problem that a drying roller of a clothes dryer can rotate towards two directions, the time of the rotation towards the two directions can be controlled at will and is not influenced by the air volume and the air pressure of a fan, so that the problems of winding and knotting of large clothes and incomplete drying inside the clothes are solved.
