Abstract

Macchina lavabiancheria, dotata di una vasca di lavaggio (1), di un cesto (2), ruotante entro detta vasca di lavaggio ed atto a contenere gli articoli da lavoro (3), e di un motore elettrico 84) atto a far ruotare detto cesto a velocità differenziate, in cui all'inizio del ciclo di lavaggio il cesto viene portato a girare a velocità progressivamente più elevata fino a raggiungere una prima velocità stabilita (Vs), detta velocità stabilita viene mantenuta per un primo tempo (T1) prefissato, al termine di detto tempo prefissato viene scollegata l'alimentazione da detto motore elettrico (4), il cesto viene lasciato ruotare per inerzia per un secondo tempo prefissato (T2), e sono previsti mezzi atti a calcolare il carico di articoli da lavare sulla base di detti parametri rilevati.Durante detto primo tempo (T1) di rotazione a regime costante del cesto iene rilevata la coppia di trazione di detto motore e alla fine di detto tempo prefissato di rotazione inerziale viene rilevata la velocità istantanea di rotazione del cesto (Vr).Laundry washing machine, equipped with a washing tank (1), a basket (2), rotating inside said washing tank and adapted to contain the work items (3), and with an electric motor 84) adapted to make said rotation differentiated speed drum, in which at the beginning of the washing cycle the drum is brought to rotate at a progressively higher speed until reaching a first established speed (Vs), said established speed is maintained for a predetermined first time (T1), at the end of said predetermined time, power is disconnected from said electric motor (4), the basket is left to rotate by inertia for a second predetermined time (T2), and means are provided for calculating the load of items to be washed on the base of said detected parameters. During said first time (T1) of rotation at constant speed of the drum the traction torque of said motor is detected and at the end of said predetermined time of inertial rotation the web is detected instantaneous rotation speed of the drum (Vr).
