ABSTRACT:
A drying machine has a drying chamber for drying an article cleaned with an inflammable solvent as a detergent. A hot air supply channel communicates with the drying chamber and a heater is mounted in the hot air supply channel. A hot air evacuation channel communicates with the drying chamber and a hot air transfer device is mounted at a voluntary portion of the hot air supply channel and the hot air evacuation channel. A control device is provided for driving control of the heater. A first temperature sensor is mounted on the downstream side of the heater in the hot air supply channel and a second temperature sensor is mounted at a position shifted to the drying chamber in the hot air evacuation channel. The control device controls the heater so that the difference in the temperature detected by the first temperature sensor and the temperature detected by the second temperature sensor is kept within a safe temperature range.
