The invention belongs to the technical field of clothes dryers, and discloses a condensed-water recycling system and a clothes dryer. The condensed-water recycling system comprises a condenser, a water storage component and a spraying component. Condensed water in the condenser can be guided into the water storage component through an outlet pipe, and the water storage component is used for circularly filtering and storing the condensed water. The spraying component is communicated to the water storage component and a working cavity, and is used for converting the condensed water in the waterstorage component into water vapor and spraying the water vapor into the working cavity. The clothes dryer comprises the condensed-water recycling system. In the condensed-water recycling system, thewater storage component and the spray component cooperate with each other; by using the condensed water obtained through condensation by the condenser, the water vapor is sprayed into the working cavity, so that water resources are saved and an extra water adding process by a user is omitted; the spraying component can filter the condensed water, and accordingly, pipeline blocking caused by incrustation scale is effectively prevented.
