Abstract

PURPOSE:To ensure the safety of drying operation and improve finish drying operation by detecting the removal of solvent from clothes in a liquid removing process according to the rotational frequency of a drum to inhibit the drying operation if the solvent is not removed. CONSTITUTION:When a timer 27 counts a liquid removing time without abnormal vibration, a liquid removal controller 26 stops the output and transfers the process to the next drying one. While the rotational frequency of a drum 2 is examined by a rotation detector 22 until the liquid removing time elapses, a judging section 28 judges comparatively whether or not the measured rotational frequency exceeds 5,000rpm for ensuring a normal liquid removing rate and generates the output if the former exceeds the latter. A drying flag is erected by the out put of the judging section. The rotational frequence of the drum 2 may be restrained from increase by a loosened belt, slipping pulley, etc. In the drying process the presence of the drying flag is first examined and if the flag is not erected, a drying inhibiting section 29 inhibits the drying operation to indicate and inform the inhibition of drying through an indication- information device 25.
