The invention discloses a clothes drying machine or washing and drying integrated machine. The clothes drying machine or washing and drying integrated machine comprises a drum, a support, a dryer and a filter screen assembly; a cavity is defined in the drum, and an airflow outlet and an airflow inlet which are communicated with the cavity are formed in the wall of the drum; the support is connected to the drum and provided with an airflow channel, and one end of the airflow channel is communicated with the airflow outlet; the dryer is arranged on the drum, a dryer inlet of the dryer is communicated with the other end of the airflow channel, and a dryer outlet of the dryer is communicated with the airflow inlet; the filter screen assembly is installed in the airflow channel of the support and partitions the airflow channel for filtering. According to the clothes drying machine or washing and drying integrated machine, by arranging the filter screen assembly in the airflow channel of the support, the phenomenon that soft flocks follow air to enter the dryer is avoided, the air supply capacity of a vane wheel is guaranteed, and the drying efficiency of the clothes drying machine or washing and drying integrated machine is improved.
