洩れの心配はない。When the washing process is completed, a dehydration process is started.
In this dehydration step, the water in the washing tub 7 is discharged from the drain valve 30, and at the same time, the solenoid 32 is energized, and the clutch 15 is operated to connect the washing input shaft 13 and the dehydration shaft 4. As a result, the rotation of the drive motor 14
The washing tub 7 fixed to the pulsator 12 and the dehydrating shaft 4 rotates via the washing shaft 9. The water content of the laundry that has been washed by the rotation of the washing tub 7 is squeezed out into the receiving cylinder 3 from a large number of small holes 5 provided in the inner peripheral wall of the washing tub 7 by centrifugal force. The laundry is thus dehydrated. During dehydration, the receiving cylinder 3 is naturally shaken due to the imbalance of the dewatering tank 7 and the like, but the swing is absorbed by the suspension 2 and the fluid balancer 6. Further, the receiving cylinder 3 of the movable portion is a drying device 1 which is a fixed portion attached to a part of the outer tub 1.
9 is connected by bellows A27 and bellows B28, so that its movement is not hindered. During the dewatering process, the gate valve 29 closes the passage as in the washing process, so that there is no fear of water leakage.

In this drying step, the washing input shaft 13 and the spin-drying shaft 4 are disconnected by the clutch 15 in the same manner as in the washing process, and the rotation of the drive motor 14 is not transmitted to the spin-drying shaft 4. Only transmitted to the pulsator 12 via the mechanism 11 and the washing shaft 9, the dehydrating shaft 4 and the dehydrating shaft 4
Are fixed to the stopped state. In this state, first, the gate valve 29 opens its passage, and the drain valve 30 also keeps its passage open for a certain period of time with the heat exchanger 2 open.
A large amount (about 2,000 cc / min) of water is supplied from a hot air cooling water supply port 25 provided in a horizontal portion 23 which forms the upper part of the nozzle 2. A large amount of water is supplied to the horizontal part 23 and the vertical part 2

At the same time, the drive motor 14 is energized and the pulsator 12 starts rotating.
The warm air heated to 0 (about 1000 liters per minute) is blown out from the upper part of the receiving cylinder 3 toward the laundry in the washing tub 7 through the bellows A27 by the blower 21. The moisture gradually evaporates from the laundry stirred by the pulsator 12 due to the warm air, and the warm air containing the moisture is sent to the receiving cylinder 3 through the small hole 5 of the first rinsing tub 7 and then from the lower part of the receiving cylinder 3 Gate valve 29,
It is sent to the rear heat exchanger 22 after passing through the bellows B28.
Then, a small amount of cooling water supplied from a cooling water supply port 25 provided in a horizontal portion 23 of the heat exchanger 22 and hitting a water splashing rib 26 provided inside a lower portion of the vertical portion 24 is blown up to be sprayed. Then, it comes into direct contact with the cooling water and condenses the moisture contained in the warm air, and dehumidification proceeds.
