A washing and drying machine (1) has a treatment tub (4), for containing articles that are to be washed and dried, and comprises: a washing circuit (5, 10, 11, 12, 21, S), for drawing in a washing liquid from the tub (4) and conveying it back into the tub, the washing circuit (5, 10, 11, 12, S) having a pump (11) and means for heating the washing liquid; a drying circuit (13, 14, 25, 26), for extracting in a forced way air from the tub (4) and conveying it back into the tub, the drying circuit (13, 14, 25, 26) having a first fan (14), means for dehumidifying the air extracted from the tub (4), and means for heating the dehumidified air to be conveyed back into the tub (4); and a heat-pump arrangement (20) having a refrigerating circuit for a refrigerant fluid, which includes a first condenser (21), a first evaporator (22), a first lamination valve (23), and a compressor (24). The means for heating the washing liquid comprise the first condenser (21), and the refrigerating circuit of the heat-pump arrangement (20) further comprises a second condenser (25), in series to the first condenser (21), and a second evaporator (26). The means for dehumidifying the air extracted from the tub (4) comprise the second evaporator (26), and the means for heating the dehumidified air to be conveyed back into the tub (4) comprise the second condenser (25). |
