Title:
DRYING AIR VOLUME-ADJUSTING METHOD FOR DRY CLEANING
Document Type and Number:
Japanese Patent JPH03123589
Kind Code:
A
Abstract:

PURPOSE: To reduce the cost of a drying process, by a method wherein in process of a drying process of dry cleaning, a drying fan-motor is normally rotated is the first half process and is reversely rotated in the second half, so that air volume is varied.

CONSTITUTION: A plurality of blades 53 are located radially in centering around a connected part and on a concentric circle. Each of the blades 53 has a specified radius of curvature and the center of the radius exists in the same direction against the rotation of an impeller 51. In process of a drying process of dry cleaning, a fan is normally rotated in the direction of an arrow mark 'a' in the early stage of drying and after that, it is reversely rotated in the direction of an arrow mark 'b'. In the early stage thereof, a large amount of air is circulated between an air duct 19 for recovery and a processing receptacle 10, and a large amount of energy is applied to clothes. In the late stage thereof, the amount of the air is made smaller to the level of 1/2 to 3/4 as compared with that of the early stage thereof and is also circulated, so that an effect of deep cooling is heightened. In this way, the recovery ratio of a solvent in the late stage is raised using the same refrigerating machine.
