method for determining volume and / or tissue type introduced in a lavabiancheria.

摘要

The present invention refers to a method for the indirect recognition of the quantity and type of fabric introduced in a laundry washing machine. Said method is based on the physical capacity of fabrics to absorb water inside a laundry washer, according to a way which depends upon their type and quantity of fiber. Such a method provides the execution of three water inlet phases while the drum is at standstill (T1,T3,T5) being intercaled with two phases (T2,T4) during which the drum is rotated to allow water absorption by the fabric. The second (T3) and third (T5) water inlet phases are switched in at the end of two different time intervals (T2,T4) starting from the beginning of the respective previous water absorption phases and are stopped when the water level in the drum reaches a preset working level. The length of time of the second (T3) and third (T5) water inlet phases allows the control system to identify the type and quantity of fabric being present within the machine. IMAGE
