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. After that, it is guided to the dehumidifying device 30.

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 the unbalance of the clothes and the like, the duct 23 and the exhaust duct 31 communicating therewith are made of flexible members, but the wear and the swing of the material due to the swing become extremely large. In some cases, this cannot be absorbed, 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.

An object of the present invention is to eliminate the disadvantages of the prior art and to dry the laundry contained in the washing and dewatering tub by contacting it with warm air for drying, and to evaporate the laundry in the drying step. It is an object of the present invention to provide a low-cost washing / drying machine that can efficiently and surely collect water with a simple structure without particularly providing a flow path for dehumidification.

It can be prevented from flowing inside the dewatering tank,
It is possible to prevent cooling water from splashing on the dried laundry in the washing and dewatering tub.

Third, since the balancer has an inclined surface whose upper surface becomes lower toward the outer dehumidifying space, the cooling water dropped on the balancer is subjected to the washing and dehydrating tub along the inclination. It surely flows to the outer peripheral side. Therefore, it is possible to prevent the cooling water from flowing into the washing and dewatering tub, and to prevent the cooling water from being applied to the dried laundry in the washing and dewatering tub.

Fourth, since the balancer has a projection formed by a rib or the like inside the upper surface, even if the cooling water dropped on the balancer tries to flow inside the washing and dewatering tub,
The protrusion prevents outflow into the tank. Therefore, it is possible to prevent the cooling water from flowing into the washing and dewatering tub, and to prevent the cooling water from being applied to the dried laundry in the washing and dewatering tub.

Fifth, since the top surface of the balancer is formed into a fine uneven surface, the cooling water dropped on the balancer scatters finely in all directions on the uneven surface and flows into the dehumidifying space as fine water droplets. The condensation action in the dehumidifying space is improved, and dehumidification can be performed efficiently.

Sixth, a cooling water dropping hole for the water supply section is formed in the water tank cover, and the cooling water dropping hole is located on the periphery of the washing and dewatering tank side, and a circumferential wall is protrudingly provided on the lower surface of the water tank cover. As a result, the cooling water dropped from the dropping hole flows downward along the peripheral wall, and does not flow toward the inside of the washing and dewatering tub.

Seventh, when the cooling water is dropped, the washing and dewatering tub is rotated so that the dropped cooling water is scattered and supplied to the gap space by its centrifugal force.
