"Apparatus And Method For Measuring Load In Washing Machine Employing Speed Sensing System Using Photo Interrupter"
Abstract: The invention provides an apparatus and method for measuring load in washing machine employing speed sensing system using photo-interrupter. The load of clothes in a washing machine is calculated by calculating total inertia of the system. Total inertia of the system can be calculated by measuring line voltage, acceleration time, deceleration time and motor torque. Line voltage can be measured by the electronic control, acceleration and deceleration time can be measured by speed sensing system and motor torque can be measured by look-up table. The washing machine employed this method for measuring load is capable of reducing cost with a simple construction without requiring sensors and signal processing circuit.
