Abstract
PURPOSE: To perform simple detection of dry level of beddings in bedding dryer or the like by detecting the change in the number of revolution of a motor for blowing hot air.
CONSTITUTION: In an initial stage of drying, because of a high air humidity of the bedding 5 and a large ventilation resistance, the number of revolution of the air blowing motor is small. But as the drying progresses, the ventilation resistance decreases leading the number of revolution of the motor to increase. Accordingly, the number of revolution is detected by a revolution detection circuit 6 to calculate the change in the number of revolution of the motor increasing with a progressing dryness by means of a main control circuit 7. When the results reach a preset level, a stop signal is generated to turn off the power source of the motor 2, thereby enabling simple control of dry levels.
