The invention relates to a clothes dryer. The clothes dryer comprises a drum, wherein a flange is arranged on the rear side of the bottom of the drum, and the bottom of the drum is fixedly connected with the flange through bolts; a protective cover is installed on the front side of the bottom of the drum and covers the junction of the boltss so as to enable the junction of the bolts to be hidden behind the protective cover and preventing clothes from being grasped by the junction of the bolts; in the clothes dryer, the drum and the flange are fixed together through the four bolts, and it can be clearly seen that the four bolts are exposed outside when a person looks at the interior of the clothes dryer from an observation window; the four exposed blots not only affect the refinement of products, but also bring damage to the clothes because the clothes are grasped by heads of the bolts in a drying process. According to the clothes dryer, since the four bolts at the junction of the drum of the clothes dryer and the flange are covered through the protective cover, the refinement of the products is improved, and the occurrence that the clothes are grasped by the heads of the bolts are avoided.
