APPARATUS AND METHOD FOR DETECTING MALFUNCTION OF A CLUTCH OF WASHING MACHINE |
摘要 |
Device and method for detecting malfunction of a clutch in a washing machine, the device including a clutch including a coupling for transmission of a power from a motor to a washing shaft or a spinning shaft, a clutch motor (60) for providing a power to the coupling, a switch for controlling the coupling, and a cam (600) fitted to be rotatable with the clutch motor for turning on/off the switch in response to the rotation, a power supplying part for supplying a voltage to the motor and the clutch motor (60), a pulse counting part for counting a number of pulses of a voltage supplied to the clutch motor from the power supplying part, and a microcomputer for repeating a process in which the clutch motor is stopped for a second set time period (S20) and operated again if the switch is not switched for a first set time period from a time the clutch motor is put into operation, and informs to a user that the clutch is in malfunction if the switch is not switched while the process is repeated equal to or more than a set times, thereby determining the clutch of being out of order and informing a result of the determination to a user. |
