Method for operating a laundry washing appliance and laundry washing appliance implementing the same
First Claim
1. A method for operating a laundry washing appliance comprising a washing chamber to wash goods according to a wash program selected by a user including at least a washing cycle, said method including:
- adding a detergent to a washing liquor within the washing chamber during a washing phase of the washing cycle, the washing phase having a predefined duration;
performing a plurality of measurements of the conductivity of the washing liquor in order to collect a set of conductivity measurements defining a conductivity curve;
analyzing the set of conductivity measurements in order to determine when a steady condition of the conductivity measurements is reached and/or detect when the related conductivity curve shows a peak;
extending the predefined duration of the washing phase, when during a first preset time period starting from the beginning of the washing phase, it is determined that no conductivity increase or peak in the conductivity curve is detected; and
extending the predefined duration of the washing phase, when after a second preset time period starting from the beginning of the washing phase and ending after the first preset time period, it is determined that the steady condition of the conductivity measurements has not been reached.

Abstract
A method (100) for operating a laundry washing appliance (10), such as a washing machine or a combined washer-dryer, having a washing chamber (12) to wash goods according to a wash program selected by a user including at least a washing cycle. The method includes adding (110) a detergent to a washing liquor (15) within the washing chamber (12) during a washing phase of the washing cycle, the washing phase having a predefined duration; performing (130) a plurality of measurements of the conductivity of the washing liquor (15) in order to collect a set of conductivity measurements (C1, . . . , Cn) defining a conductivity curve analyzing the set of conductivity measurements (C1, . . . , Cn) in order to determine (150) if a condition of substantial invariability of the conductivity measurements (C1, . . . , Cn) is reached and/or detect (140) if the related conductivity curve shows a peak. The method also includes extending (160) the predefined duration of the washing phase, if after a first preset time period (Tref) starting from the beginning of the washing phase, no conductivity increase or peak in the conductivity curve is detected; and/or extending (160) the predefined duration of the washing phase, if after a second preset time period (Tref′) starting from the beginning of the washing phase, the condition of substantial invariability of the conductivity measurements (C1, . . . , Cn) has not been reached.
