Abstract

A method for setting a time of a release of a cleaning agent during a cleaning cycle in a household appliance includes obtaining an evolution over time of a local parameter inside the appliance, the local parameter comprising an acceleration induced by the cycle or a temperature inside the appliance; obtaining reference patterns of evolutions of the local parameter during a cycle comprising different cleaning steps including a step adapted for releasing the cleaning agent at a predetermined adapted time; comparing the evolution of the local parameter to the reference patterns and identifying a cleaning step within the cycle when a similarity between a reference pattern and the evolution is above a predetermined threshold, and setting the release of the agent at the predetermined adapted time within the identified cleaning step when the identified step corresponds to a step adapted for releasing the agent.
