Abstract

UNA LAVADORA, TIPICAMENTE DE CARGA VERTICAL, PROVISTA DE UNA CUBA DE LAVADO, UN TAMBOR CILINDRICO (2) ADAPTADO PARA CONTENER LA COLADA (1), QUE SE CARGA EN EL MISMO A TRAVES DE UNA TAPA (3) QUE CIERRA UNA ABERTURA PROVISTA EN UNA PARTE DE LA SUPERFICIE DEL TAMBOR, UNA PLURALIDAD DE ELEVADORES DEL TIPO REFORZADO (4) DISPUESTOS EN LA SUPERFICIE INTERNA DE DICHO TAMBOR, CARECIENDO ESTE ULTIMO DE PESO-COMPENSADOR DE MASA PARA EQUILIBRAR EL PESO DE LA TAPA. LA LAVADORA ESTA PROVISTA DE MECANISMOS ADAPTADOS PARA IDENTIFICAR LA POSICION DE LA TAPA DE CARGA, PARA PERMITIR QUE EL TAMBOR CONTINUE ROTANDO DURANTE UN PERIODO DE TIEMPO PREDETERMINADO A UNA VELOCIDAD DE REVOLUCIONES ADECUADAMENTE BAJA, PARA PERMITIR QUE LA COLADA SE AGRUPE EN EL FONDO DEL TAMBOR, Y PARA PERMITIR QUE EL TAMBOR EMPIECE A GIRAR CUANDO DICHOS MECANISMOS INDIQUEN QUE LA TAPA DE CARGA HA ALCANZADO SU POSICION SUPERIOR. UNA VARIANTE DE LA INVENCION CONSISTE EN INTRODUCIR ANTES DE LA EXTRACCION GIRATORIA UNA FASE EN LA QUE SE PERMITE QUE EL TAMBOR ROTE A UNA VELOCIDAD QUE, AUNQUE GENERALMENTE ES BAJA, SEA ADECUADAMENTE ALTA PARA PERMITIR QUE LA COLADA SE DISTRIBUYA A LO LARGO DE LA PERIFERIA INTERNA DEL TAMBOR, MIENTRAS LA FASE DE EXTRACCION GIRATORIA SE EMPIEZA TAN PRONTO COMO SE DETECTE QUE SE PRODUCE UN DESEQUILIBRIO EN UN VALOR INFERIOR A UNO PREDETERMINADO.A WASHING MACHINE, TYPICALLY WITH VERTICAL LOAD, PROVIDED WITH A WASHING TANK, A CYLINDRICAL DRUM (2) ADAPTED TO CONTAIN THE CAST (1), WHICH IS LOADED THROUGH A LID (3) THAT CLOSES AN OPENING PROVIDED IN A PART OF THE SURFACE OF THE DRUM, A PLURALITY OF ELEVATORS OF THE REINFORCED TYPE (4) ARRANGED ON THE INTERNAL SURFACE OF SUCH DRUM, LACKING THIS LAST WEIGHT-WEIGHT COMPENSATOR TO BALANCE THE WEIGHT OF THE TOP. THE WASHING MACHINE IS PROVIDED WITH ADAPTED MECHANISMS TO IDENTIFY THE POSITION OF THE CHARGING LID, TO ALLOW THE DRUM TO CONTINUE ROTATING DURING A PERIOD OF TIME DEFAULT TO A SUBSTITUTE RATE, FOR PERMIT , AND TO ALLOW THE DRUM TO BEGIN TO TURN WHEN SUCH MECHANISMS INDICATE THAT THE LOAD LID HAS REACHED ITS SUPERIOR POSITION. A VARIANT OF THE INVENTION CONSISTS OF INTRODUCING BEFORE THE ROTATING EXTRACTION A PHASE IN WHICH THE DRUM IS ALLOWED TO ROTATE AT A SPEED WHICH, WHETHER GENERALLY IS LOW, IS SUITABLY HIGH TO ALLOW THE LAUNDRY TO BE DISTRIBUTED TOWARDS THE LAUNDRY. INTERNAL OF THE DRUM, WHILE THE ROTATING EXTRACTION PHASE BEGINS AS SOON AS IT IS DETECTED THAT AN IMBALANCE IN A VALUE LESS THAN ONE DEFAULT.
