Title:
DRIVE DEVICE OF DEHYDRATING WASHING MACHINE
Document Type and Number:
Japanese Patent JPS59156173
Kind Code:
A
Abstract:
PURPOSE:To improve the attracting force at the starting time by connecting a switch which is operated by a starting current and maintains the operating state while a voltage of the prescribed value or higher is being applied. CONSTITUTION:A switch 2 is connected between leads wirings led from the midway of a main winding 3 of a dehydrating motor 1 and one end lead wirings of a man coil 3. The switch 2 interrupts energization since a responding piece 2' is slacked in a direction that a contact is separated by the self-heat generation when a current of the prescribed value or higher is flowed at the starting time. After interruption, this state is maintained by the heat of a positive temperature coefficient thermistor 2'' which is connected between the contacts. Since only the part (a) of the main coil 3 can be used at the starting time, the ratio of windings can be increased, and the torque and attracting force at the starting time can be increased.
