ABSTRACT:
A cloth amount detecting device in a washing machine including a process controller for controlling a process of washing, rinsing and spin-drying cloths put into the washing machine is designed to detect the amount of the cloths. If the user of the washing machine changes the level of water within the washing machine to a different water level after the amount of cloths has been detected, a reference value used to determine the amount of cloths is updated by learning in dependence on the water level so changed by the user and the number of waveforms of a drive motor, to thereby accomplish a determination faithful to the amount of cloths.
