That is, a Water supply operation by the water supply device 81 b Washing operation based on the rotation of the inner tank 30 C Drainage operation by opening the drain valve 85 d Dewatering operation based on the rotation of the inner tank 21 e Water supply operation by the water supply device 81 f By the water supply device 81 Water supply and rinsing operation based on the rotation of the inner tank 21 (g>drainage operation by opening the drain valve 85 (h))
(i) A drying operation based on the rotation of the inner tank 30 and the supply of warm air by the hot air supply device 94.

(Details of Operation) Next, each of the above-mentioned operations (a) to (i) will be explained in detail.

(Washing, rinsing, spin-drying, and drying operations) Now, when washing is performed with the main body opening/closing lid 4 and the lid 37 both closed and the laundry stored in the inner tub 30 in advance as described above, When a switch (not shown) is operated, the drain valve 85 is automatically closed, and the spring clutch 7 is automatically closed.
1 enters the cutoff state, and the brake body 75 enters the braking state to restrict the rotation of the middle ffI 21. In this state, the water supply valve of the water supply device 81 is opened, and water is supplied into the outer tank 15 through the water supply port 82. When the water level in the outer tank 15 reaches the inside of the inner Wi 30 and reaches the normal water level Wn, the structure movement motor 51 is rotated, and the inner tank 30 is rotated around the horizontal axis X-X. A washing operation is started.

During this washing operation, the spherical inner tub 3 containing the laundry
0 is rotated around the horizontal axis X-x, and along with the rotation, the laundry is rolled by the plurality of reversing protrusions 34, 40, etc., and so-called beating washing is performed.

In addition, when rinsing is performed after washing the laundry, the inner tub 30 is
is rotated. Furthermore, when the water supply valve of the water supply device 81 is opened, water is supplied from the water supply port 82 toward the upper surface of the outer circumference of the inner tank 30, and the rinsing water in the outer tank 15 passes through the overflow port and overflow hose 87 (not shown). The water level is maintained constant. Therefore, while the rinsing water is replaced in sequence, the water from the water supply port 82 effectively washes away the foam adhering to the outer peripheral surface of the inner tub 30 and the laundry inside the inner tub 30. .

Furthermore, when dewatering is performed after washing or rinsing the laundry, the spring clutch 71 is brought into a connected state, and the brake body 75 is brought into a non-braking state to allow rotation of the inner tub 21. In this state, when the structure movement motor 51 is rotated, the inner tank 21 and the inner tank 30 are integrally moved along the vertical axis a.
The laundry is rotated at high speed around Y-Y to dehydrate the laundry.

When the laundry is dried after being dehydrated, the inner tub 30 is rotated around the horizontal axis X-X by the structure movement motor 51, and the fan motor 96 and By energizing the heating heater 98, hot air is generated from the hot i generation source 95 of the hot air supply device 94, and the hot air is delivered to the connecting cylinder 100, the hot air supply passage 99, and the air outlet 101.
and is supplied into the inner 130 via the rear shaft portion 20A,
It is discharged from each small hole 35 and the shaft portion 20B. Therefore, without rolling the laundry, hot air can be applied to the laundry to effectively dry the laundry.

During this drying operation, the hot and humid air in the inner tank 30 flows from an overflow port (not shown) provided in the outer tank 15 that also serves as a hot air exhaust port, through an overflow hose 87, and into the expansion cooling chamber 88.
After being cooled and dehumidified in the overflow hose 87, expansion cooling chamber 88, etc., it is discharged to the outside through the drainage hose 86.

Now, in this embodiment, a stainless steel cylindrical body 29 that is not easily deformed by heat is slidably fitted into the bearing 28A of the inner tank 21111I with respect to the fixed part 30c formed protruding from the inner tank 30.
At the tip of the cylindrical body 29, a drop-off prevention ring 31 that engages with the side of the bearing 28A is provided, and this is engaged with the engagement groove 28a, so that heavy laundry cannot be washed during the washing operation. When the accommodated inner tank 30 is rotated, or when the inner tank 30 is rotated in a heated state during drying operation, the mechanical strength of the shaft portion 20A is ensured, and the wear of the bearing 28A and the cylindrical body 29 is prevented. This prevents deformation and deformation, and also prevents the shaft portion 20A from detaching from the bearing 28A. Moreover, since stainless steel has a small coefficient of friction, smooth rotation of the inner WJ 30 can be obtained.

In addition, in the embodiment, since the net plate part 30a is integrally formed with the inner tub 30 so as to cover the inner opening of the cylindrical body 29, the laundry does not get inside the cylindrical body 29 during washing and drying operations. It can prevent intrusion.

For this reason, the laundry is effectively rolled near the center of the inner WJ30, and the laundry does not become an obstacle to the passage of warm air.
It is possible to perform stable washing and drying operations by preventing washing from not being carried out effectively.

Furthermore, in the embodiment, the fixing parts 30c are formed radially in a fan shape as a whole, and each fixing part 30C
Since the hot air introduction hole 30b is formed in the net plate part 30a located between the two, the fixed part 30c rotating together with the inner tank 30 acts as a fan during the drying process, so that the hot air is circulated by centrifugal force. The warm air is also guided outward and introduced into the inner tank 30 through the entire net plate portion 30a, and is discharged from the entire mesh plate portion 30a on the opposite side, so that the warm air flows into the inner tank 30. It passes through the entire interior of the inner tank 30 without passing only through the center, and efficient drying is performed within the inner tank 30.

The present invention is not limited to the above-mentioned embodiments, but the gist of the present invention can be modified, for example, by providing joints or mesh plates made of stainless steel only on the shaft portion on the hot air introduction side. The configuration can be changed and implemented as desired without departing from the scope.

[Effect of the invention] Since this invention is configured as explained above,
This has the effect of preventing deformation of the bearing and shaft due to ripening, allowing accurate and smooth rotation of the inner tub during washing and drying processes, and improving durability.
