Abstract

A clothes drier according to the present invention can minimize failures in a sensor and can satisfactorily detect drying processing irrespective of the environment. In the clothes drier, an atmospheric temperature sensor 44L for detecting the substrate temperature required to determine the termination of the drying processing is disposed outside a circulating duct 18 and is mounted on a control substrate 42 having a thermal capacity on which a microcomputer for controlling operations performed by the clothes drier is mounted. Since the sensor 44L is provided outside the circulating duct 18, the sensor 44L is less affected by dust and water, as compared with a case where it is provided inside the circulating duct 18.
