Patent CA-2006005-A1 (CA)
IPC: D06F33/48
Filed: 1989-12-19
Abstract: Abstract of the Disclosure Load unbalance in an inverter driven washing machine is detected by examining the ripple in the DC inverter bus current.          Ripple above a predetermined level is indicative of load unbalance.  If the ripple indicates the load is unbalanced, the distribution cycle of the washing machine is attempted again in an attempt to more nearly balance the clothes.  After a certain number of tries, if the load is still unbalanced the spin cycle is aborted.  If the ripple falls below a predetermined level before the maximum number of tries is reached, the spin cycle is started.  The frequency of operation is checked during the spin cycle to adjust the cycle time to the particular degree of load balance achieved.
