ABSTRACT:
An energy saving method of operating a washing machine such that the amount of water added to the washer basket is proportionate to the weight of the articles to be washed includes the steps of determining a normalized inertia of the washer basket loaded with articles to be cleaned; determining an estimated weight of the load of articles to be washed based upon the normalized inertia value; and controlling a washer water supply system to add a load-specific volume of water to the washer basket, the magnitude of the load-specific volume of water corresponding to the estimated weight of the articles to be washed. An energy efficient washing machine in accordance with this invention includes an induction motor coupled to the washer basket, a washer water supply system coupled to the washer basket, and a washer controller coupled to the drive motor and the washer water supply system so as to respectively control operation thereof. The washer controller includes a load weight circuit for generating control signals for the washer water supply system to add a load-specific volume of water to the washer basket in correspondence with an inertia-based estimated load weight signal generated by the load weight circuit.
