Abstract

UN METODO PARA LA REALIZACION DEL EQUILIBRADO DE LA CARGA EN MAQUINAS LAVADORAS PROVISTAS DE UN TAMBOR DE ROTACION DIRIGIDO POR UN MOTOR ELECTRICO BAJO EL CONTROL DE ELEMENTOS DE CONTROL, Y EN EL QUE UN CIRCUITO SE ENCARGA DE MEDIR UNA CANTIDAD FISICA ASOCIADA CON INFORMACION RELATIVA AL ESTADO (EQUILIBRADO O NO EQUILIBRADO) DE LA CARGA DE DENTRO DEL TAMBOR, EL METODO COMPRENDE, DESPUES DE LA FASE DE LAVADO, UNA FASE DURANTE LA CUAL LA VELOCIDAD DEL TAMBOR SE INCREMENTA GRADUALMENTE EN EL QUE LA CANTIDAD FISICA SE SUPERVISA CONTINUAMENTE PARA DETERMINAR EL ESTADO DE DISTRIBUCION DE LA CARGA DENTRO DEL TAMBOR, Y UNA FASE DE INCREMENTO DE LA VELOCIDAD ROTACIONAL RAPIDA EN EL MOMENTO EN QUE SE DETECTA DENTRO DEL TAMBOR UN ESTADO DE DISTRIBUCION DE CARGA EQUILIBRADA.A METHOD FOR THE PERFORMANCE OF BALANCING THE LOAD IN WASHING MACHINES PROVIDED WITH A ROTATION DRUM DIRECTED BY AN ELECTRIC MOTOR UNDER THE CONTROL OF CONTROL ELEMENTS, AND IN WHICH A CIRCUIT IS IN CHARGE OF MEASURING A PHYSICAL QUANTITY ASSOCIATED WITH INFORMATION RELATING TO STATUS (BALANCED OR UNBALANCED) OF THE LOAD WITHIN THE DRUM, THE METHOD INCLUDES, AFTER THE WASHING PHASE, A PHASE DURING WHICH THE SPEED OF THE DRUM IS INCREASED GRADUALLY IN WHICH THE PHYSICAL QUANTITY IS SUPERVISED TO CONTINUE STATUS OF LOAD DISTRIBUTION INSIDE THE DRUM, AND A PHASE OF INCREASING RAPID ROTATIONAL SPEED AT THE TIME A BALANCED LOAD DISTRIBUTION STATUS IS DETECTED INSIDE THE DRUM.
