Abstract: A method and apparatus determines a load size of a laundry load located in a laundry treating appliance having a drum defining a treatment chamber that is rotated by a motor based on a given amount of energy applied to the motor, and a measurement of coast time after the given amount of energy is removed.

Abstract: The present invention refers to a method for determining loads in clothes washing machines which comprises the following steps: (E1) Acceleration of the mobile assembly of the washing machine until the mobile assembly reaches a low rotation speed; (E2) Acceleration of the mobile assembly until the mobile assembly reaches a medium rotation speed faster than the speed in the first step (E1); (E3) Deceleration; (E4) Acceleration of the mobile assembly and measurement of the engine current; (E5) Measurement, whereby parameters regarding the engine are measured; (E6) Shutdown of the engine and measurement of the deceleration time; (E7) Repetition, whereby the forth (E4), fifth (E5) and sixth (E6) steps are repeated at least once before the performance of the eighth step (E8); (E8) Calculation of the average of each one of the parameters measured in the fourth, fifth, sixth and seventh steps; and (E9) Obtainment of clothes load value.
