Title:
SUCTION TYPE IRONING STAND
Document Type and Number:
Japanese Patent JPH04176500
Kind Code:
A
Abstract:

PURPOSE: To improve the efficiency of ironing-work by obtaining sufficient suction force just after the ironing-work begins to be started, by a method wherein driving torque by a motor is increased until the motor reaches a specified speed.

CONSTITUTION: When a worker lifts an iron placed on a placing stand 4, a placement-detecting means detects it. An unplaced signal from the placement- detecting means is inputted by a control means 12, and it is started to apply an electric current to a motor 9. The number of revolution of the motor 9 does not immediately reach a specified speed because of the load by a fan, etc. To increase the torque of the motor 9, a signal is sent from a speed- detecting means 13 to the control means 12 to raise the input voltage to the motor 9. When the motor 9 reaches the specified speed, a signal is outputted from the speed-detecting means 13 to the control means 12 to drive the motor 9 at steady-state torque. Therefore, the rotation of the motor 9 instantaneously reaches the specified speed.
