Efficient energy usage for a laundry appliance

摘要

A washing machine (10) comprising a rotatable drum (16) at least partially defining a treating chamber (18) for receiving a laundry load for treatment according to at least one cycle of operation and operated such that the extraction of liquid from the laundry load is controlled based on the inertia of the laundry load so that the total energy usage by the washing machine (10) and a laundry drying appliance (142) with which said washing machine (10) is operably coupled may be minimized.
