AUTOMATIC WEIGHING METHOD OF LAUNDRY IN WASHING MACHINE

摘要

Automatic weighing method for washing machine, where determination of temperature of an engine by frequency modulator is processed, during that measuring of amount of current passing through the winding of the engine of the washing machine during its inaction is done, and afterwards calculation of resistance of the winding of the engine of the washing machine based on amount of measured current is effected, afterwards angular speed of the drum of the washing machine is increased up to distribution angular speed (ω0), which is intended to distribute laundry in the drum of the washing machine, afterwards angular speed of the drum of the washing machine is increased up to medium angular speed (ω1), which is intended to spread the laundry on the inner surface of the drum of the washing machine, afterwards angular speed of the drum of the washing machine is decreased up to measuring angular speed (ω2), during that a value of unbalance of the drum of the washing machine is determined, afterwards angular speed of the drum of the washing machine is increased up to maximal angular speed (ω3), during that energy consumed for acceleration of the drum of the washing machine is measured.
