Abstract
Dispositivo elettronico di misurazione e di equilibratura di carichi squilibrati nel cesto di macchine lavatrici, prodotti da una distribuzione disuniforme del carico di biancheria nel cesto durante la sua rotazione alle velocità di lavaggio e di centrifugazione. Dispositivo che misura la potenza attiva assorbita dal motore (1) d'azionamento del cesto, potenza che è proporzionale alle sollecitazioni meccaniche e cui è soggetto il cesto stesso, e che confronta (in un comparatore 27) il valore di tale potenza attiva con una potenza di riferimento prestabilita, corrispondente alla potenza attiva assorbita dal motore (1) quando inizia a manifestarsi lo squilibrio del carico nel cesto. In dipendenza di tale confronto, il comparatore (27) provvede ad azionare il motore (1) in modo regolare, se non c'è lo squilibrio, e varia la velocità di rotazione del motore stesso nel caso in cui sia presente tale squilibrio, e tale variazione viene eseguita finché la biancheria si è ridistribuita uniformemente nel cesto e lo squilibrio viene pertanto annullato.Electronic device for measuring and balancing unbalanced loads in the drum of washing machines, produced by a non-uniform distribution of the load of laundry in the drum during its rotation at the washing and spin speed. Device that measures the active power absorbed by the drum drive motor (1), power that is proportional to the mechanical stresses to which the drum itself is subjected, and that compares (in a comparator 27) the value of this active power with a predetermined reference power, corresponding to the active power absorbed by the motor (1) when the load imbalance in the drum starts to appear. Depending on this comparison, the comparator (27) operates the motor (1) on a regular basis, if there is no imbalance, and the rotation speed of the motor itself varies in the event that such imbalance is present, and this variation is carried out until the laundry has been uniformly distributed in the drum and the imbalance is therefore canceled.
