Abstract:
1. A household appliance ( 1 ) that comprises a clock ( 2 ) for measuring time, a sensing means ( 3 ) that detects a discounted rate energy signal coming from an energy network momentarily when connected to the energy network which energy network delivers the discount rate energy wherein the energy tariff changes dynamically, a control unit ( 4 ) that evaluates the clock ( 2 ) and the signal received from the sensing means ( 3 ) and a panel ( 5 ) which enables the user to select programs and wherein the control unit ( 4 ) that maintains to execute the program as much as possible in the time interval when the discounted rate is applied when the user enters the desired end time (t f ) for the program to be executed, by evaluating together the clock ( 2 ) data and the momentary energy tariff signal received from the sensing means ( 3 ) within the time passing until the end time (t f ) and guarantees completion of the program to be executed before the selected end time (t f ).
