In this drainage process, first, the drainage control unit 26 opens the drainage valve 16 and controls the drum 2 by an inverter so that the drum 2 rotates in one direction at 600 rpm. Next, the operation of the vibration switch 4 is checked, and if it is operated, the rotation of the drum 2 is stopped, and the rotation is restarted when the rotation detector 22 detects zero rotation. The timer 27 counts the time when the vibration switch 4 does not operate.

Thus, when the timer 28 counts the liquid removal time without abnormal vibration, the liquid removal control unit 26 stops the output and shifts to the next drying process. The rotation number of the drum 2 is checked by the rotation detector 22 before the draining time elapses.
28 is 500r, where the measured number of rotations ensures a normal liquid removal rate.
Compare and determine if pm is exceeded and output when it is exceeded. Then, the dry flag is set by the output of the determination unit. The rotation speed of the drum 2 may not increase due to a loose pulley, a belt slip, or the like.

If the flag is set, the drying control unit 30 rotates the drum 2 at a low speed, drives the blower 7, and operates the cooler 8 and the heater 9 until the timer 27 counts the drying time. Then, the heater 9 is ON / OFF-controlled so that the temperature measured by the temperature sensor 10 is 38 ° C. or lower to 36 ° C. or higher. During this period, the cooler 8 condenses and collects the solvent vapor and sends it to the water separator 11.

(G) Effect of the Invention According to the dry cleaner of the present invention, even if the drum does not vibrate abnormally during the liquid removal process, the drum rotation speed is necessary for sufficient liquid removal due to the effect of loosening of the belt that drives the drum. If the predetermined number of rotations is not reached, the next drying operation is prohibited.Therefore, it is possible to prevent the gas concentration of the flammable solvent from becoming abnormally high due to the fact that the drying is performed with insufficient liquid removal, That is, the drying can be performed only in a safe state where the liquid is sufficiently removed.
