Claim:
1. An appliance for drying laundry comprising an appliance cabinet, a laundry treatment chamber inside the cabinet, a drying air recirculation path for causing recirculation of the drying air into/out from the laundry treatment chamber, the drying air recirculation path being at least partly external to the laundry treatment chamber, a drying air moisture condensing and heating system located in the drying air recirculation path for dehydrating the moisture-laden drying air leaving the laundry treatment chamber and heating the dehydrated drying air before it re-enters into the laundry treatment chamber, wherein said drying air moisture condensing and heating system comprises a first heat exchanger and a second heat exchanger of a heat pump, and further comprising a drying air propeller inside the drying air recirculation path and a Joule-effect drying air heater, downstream the second heat exchanger, energizable for contributing to the heating of the drying air, wherein the appliance comprises a user interface comprising a laundry treatment cycle selector operable by a user for selecting a laundry treatment cycle, and a control unit adapted to control the machine operation, wherein the user interface comprises a command input means distinct from said laundry treatment cycle selector and operable by the user for imparting to the appliance an energization command to energize the Joule-effect heater, and in that during the execution of the laundry treatment cycle selected by the user, said control unit causes the selective energization of said Joule-effect drying air heater based on said energization command imparted by the user, so that the activation of the Joule-effect drying air heater is not systematical but instead decided by user by input of said energization command.
