Inventor: OH MIN JIN
IPC: D06F33/02
Filed: 2002-11-26
Abstract: PURPOSE: A duty control method of a washing machine is provided to prevent damage of a circuit, and to reduce power consumption from accumulation of over current by restricting over current with controlling the duty within the acceleration range increasing current excessively considering RPM(Revolution Per Minute) and the water level. CONSTITUTION: RPM of a motor is checked, and the number for reaching the desired RPM is counted and compared with the reference number(S31). The water level is compared with the middle water level in case of the counted number to be over the reference value(S32). The duty of a first acceleration range is decreased in case of the water level to be less than the low water level(S33). The duty of a second acceleration range is decreased in case of the water level to be more than the middle water level(S34). Excessive increase of current is prevented by reducing fluctuation of RPM with decreasing the acceleration gradient.
