Abstract: Front load washing machine with incorporated drying system, with heat pump, still maintaining the advantage of performing the washing and drying within the size i.e. the standard overall size for the machines in question. Besides the washing system, the machine includes a drying system with a heat pump circuit adapted to condense the air extracted from the washing tub and subsequently reintroduced there into but heated by the heat pump circuit. The condensation and heating steps are actuated by special exchangers arranged centrally and above the washing tub and connected thereto through a series of mouthpieces or fittings, respectively for delivery and return, and front ventilator elements for the circulation of air and provided with an intermediate filter for collecting impurities. A collection tub diverts the condensate water towards the pump of the machine.
