To provide a washing and drying machine which can perform drying operations and reduce power consumption without discharging high-humidity air into a room.
In the second half of drying operations, an air intake valve is opened, high-temperature air collected in a housing is sucked by a fan and the water sealing of a drain trap is broken by rotating the fan at a high speed and the air is discharged to a drain outlet for drying by residual heat. Also, after completion of the drying operations, the rotating speed of the fan is reduced and water is supplied to the drain trap for restoring the water sealing. In this way, power consumption of the heater in the second half of the drying operations can be reduced by drying by residual heat consisting of discharging air to the drain outlet by breaking the water sealing of the drain trap without discharging high-humidity air into the room. Also, odor from the drain outlet can be suppressed also after completion of the drying operations by reducing the rotating speed of the fan, supplying water to the drain trap and restoring the water sealing after completion of the drying operations.
