Abstract
A hot air drying machine for drying materials, such as clothes or the like, includes a drum for materials to be dried rotatably supported in a housing, a fan casing communicated with the drum and enclosing therein a fan rotated simultaneously with the drum by a driving motor, and heaters for heating air sucked into the housing from exterior thereof. The drying machine further includes an electrical control circuit connected to a first temperature sensing element for hot exhaust air and a second temperature sensing element for the cool outside air sucked into the housing with the operational ratio of the first sensing element to the second sensing element adapted to vary depending on the power source voltage fluctuation for achieving uniform drying rates regardless of the variations of the power source voltage.
