Abstract: A laundry washing and drying machine (1) includes a casing (2) and, inside the casing, a laundry container (3, 6) for housing the laundry to be washed and dried, and a heat-pump-type, hot-air generator (10) able to circulate a stream of hot air inside the laundry-container (3, 6), and to heat up the washing water supplied to said laundry container (3, 6). The hot-air generator (10) includes a heat-pump assembly (21) which is provided with a first air/refrigerant heat exchanger (23) which is located along the air recirculating conduit (19) for heating up the airflow (f) directed to the laundry container (3, 6). A second water/refrigerant heat exchanger (24) is located out of the air recirculating conduit (19), and heats up or cools down the water arriving from the laundry container (3, 6). A third air/water heat exchanger (25) is located along the air recirculating conduit (19), upstream of the first air/refrigerant heat exchanger (23), for cooling the airflow (f) arriving from the laundry container (3, 6).

Abstract: A clothes treating apparatus comprising a cabinet (1) having external walls (2) and internal walls (3), said internal walls (3) defining an interior region (4) for receiving clothes, said apparatus further comprising a door (6) connected to said cabinet (1), at least a supporting device (5) for supporting clothes within said interior region, a ventilator (7), water supply means (8) and an ultrasonic nebulizer (9) operatively associated to said water supply means (8). Said apparatus is characterized in that the air within the interior region (4) is recirculated by said ventilator (7) through an air duct (10) located between said internal walls (3) and said external walls (2) forming a closed loop with said internal region.
