Abstract
A motor load detector detects an electrical value representing a rise characteristic of a motor, which varies in accordance with a load acting on the motor serving as a power source for a series of operations including a wash cycle and a spin-drying cycle executed by an electric washing machine for washing and spin-drying. A determining section receives a value detected by the motor load detector during the spin-drying cycle, and determines a weight of washings contained in the electric washing machine in accordance with a time which has elapsed until the detected value reaches a second reference value from a first reference value. The determined washings weight is used in a cycle subsequent to the spin-drying cycle.
