When the heater 0 and the heater 21 operate, warm air is generated and blown out of the duct 23 into the washing and dewatering tub 6.
In this case, the warm air flows into the clearance space B between the lower surface of the water tub cover 16 and the upper end of the washing and dewatering tub 6, and is directly blown from the clearance space B into the washing and dewatering tub 6.

The warm air that has entered the washing and dewatering tub 6 comes into direct contact with the water-containing laundry on the rotating blades 7 in the washing and dewatering tub 6 after the dehydration step, and this is dried. Let it.

The warm air, which has been deprived of the moisture contained in the laundry and has increased in humidity, passes through a vent 33 formed in the bottom of the washing and dewatering tub 6 to allow the water to flow between the water tub 5 and the washing and dewatering tub 6. Although it flows into the clearance space A, since the upward flow is blocked by the hot air backflow blocking member 24, it flows as a downward airflow through the drain pipe to the drain valve 18, and from the outlet 28 the overflow pipe 27 and the exhaust duct 31.

In the washing and drying machine as described above, the hot air backflow blocking member 24 is provided in the clearance A between the washing and spin-drying tub 6 and the water tub 5, so that the washing and drying can be performed in the drying step. The heat-exchanged air is prevented from flowing backward through the gap A between the washing and dewatering tub 6 and the water tub 5 to mix with the hot air newly supplied into the water tub 5, thereby preventing the heat exchange. The discharged air flows from the outlet 28 of the drain valve 18 through the overflow pipe 27 and the exhaust duct 31 to the dehumidifier 3
Although it is guided to zero and water is condensed and removed, there is a structural problem that the air flow path to the dehumidifying mechanism such as the overflow pipe 27 and the exhaust duct 31 has a complicated configuration. Further, since the water tank 5 swings due to unbalance of clothes and the like, the duct 23 and the exhaust duct 31 communicating with the tank are made of flexible members. Cannot absorb this, which may lead to detachment of the connection portion and destruction of components.

In addition, since a complicated air path is routed, the pressure loss increases, a large blower is required, and the cost increases.
