(Operation) Next, an outline of the operation of the dehydrating/drying/washing machine configured as described above will be explained with reference to FIG.

First, with the main body opening/closing lid 4 and the inner tank lid 37 open, the items to be washed are put into the inner tank 30, and then the inside! an body 3
7 and the main body opening/closing lid 4 are closed and a start switch (not shown) is operated, a series of operations shown in the time chart of FIG. 7 are automatically performed sequentially by a control device (not shown). That is, (a) Water supply operation by the water supply device 81 (b) Washing operation based on the rotation of the inner tank 30 by the first drive #J machine ellipse 76 (c) Drainage operation by opening the drain valve 85 (d) Second drive machine Dewatering operation based on the rotation of the inner tank 21 by the treetop 77 (e) Water supply operation by the water supply device Wt81 (f) Water supply by the water supply device 81 and the first drive! lj machine oval 7
(g) Drainage operation by opening the drain valve 85 (h) Dewatering operation based on the rotation of the inner tank 21 by the second drive mechanism 77 (i) Warming operation by the hot air supply device rI194 Dry heat operation based on wind supply and rotation of the inner Ja30 by the first drive WJm ellipse 76. Note that during each of the above operations (a) to (i), the control is performed based on a detection signal from a sensor (not shown). The device positions the inner tank 21 or 30 in the state shown in FIG. 1.

Next, each of the above operations will be explained in detail.

Now, when washing is performed with the items to be washed stored in the interior 130, the drain valve 85 is closed, the spring clutch 71 is in the disconnected state, the first drive mechanism 76 is formed, and the brake The body 75 is in a braking state and the middle tank 2
1 rotation is restricted. In this state, the water supply valve of the water supply device 81 is opened, and water is supplied into the outer tank 15 from the water supply port 82. When the water level in the outer tank 15 reaches the inside of the inner tank 30 and reaches the normal water level Wn, the seed part movement motor 5
1 is rotated, the inner tub 30 is rotated around the horizontal axis XX via the first drive mechanism 76, and a washing operation is started.

During this washing operation, the spherical inner tank 30 containing the items to be washed is rotated around the horizontal axis X-X, and as it rotates, the items to be washed are rolled by the plurality of reversing protrusions 34, 40, etc. While washing, so-called washing is performed. Therefore, the amount of water used when washing is small, and since the items to be washed are hardly twisted or tangled, the washing operation can be carried out effectively without causing any damage to the items to be washed. After the operation is finished, the washing operation can automatically shift to the draining operation and the dewatering operation without requiring the troublesome work of correcting twists and entanglements of the items to be washed.

In addition, when rinsing is performed after washing the items to be washed, the seed part movement motor 51, as in the case of washing,
First drive! ! ! The inner tank 30 is rotated via the mechanism 76.

In addition, by opening the water supply valve of the water supply device 81, the water supply port 82
Water is supplied to the outer peripheral upper surface of the inner tank 30, and rinsing water in the outer tank 15 is discharged through an overflow port and an overflow hose 87 (not shown), so that the water level is kept constant.

Therefore, while rinsing water is being replaced sequentially, the water supply port 8
The water from 2 effectively washes away the foam adhering to the outer peripheral surface of the inner tank 30 and the foam adhering to the items to be washed in the inner tank 30.

Furthermore, when dewatering is performed after the washing and rinsing of the laundry, the spring clutch 71 is brought into a connected state to form the second drive R ellipse 77, and the brake body 75
is placed in a non-braking state, and rotation of the inner tank 21 is allowed. In this state, when the seed part driving motor 51 is rotated, the inner tank 21 and the inner tank 30 are rotated at high speed around the vertical axis Y-Y through the second drive side 77, and the laundry is washed. is dehydrated. Therefore, the rotational axis of the inner tank 30 can be changed from the horizontal axis X-X to the vertical axis Y-Y without changing the orientation of the tank, without changing the attitude of the washing or rinsing operation to the spin-drying operation. By doing so, it can be done smoothly and in a short time.

In addition, when drying is performed after dehydrating the items to be washed, the inner tank 30 is rotated around the horizontal axis X-X by the handle driving motor 51 via the first driving nib 76, as in the case of washing. At the same time, by energizing the fan motor 96 and the heating heater 98, the hot air generation source 9 of the hot air supply device 94 is activated.
Warm air is generated from 5, and the warm air is supplied into the inner 1a30 via the connecting cylinder 100, the warm m supply passage 99, the air outlet 101, and the rear shaft portion 31, and is discharged from each small hole 35. . Therefore, while transferring the items to be washed, hot air can be applied to the items to be washed to effectively dry the items.

During this dry fermentation operation, the high-temperature and humid air in the inner T/A 30 flows into the expanded cooling chamber 88 through the overflow hose 87 from an overflow port (not shown) provided in the outer tank 15 that also serves as a hot m exhaust port. The overflow hose 87 and expansion cooling chamber 88
After being cooled and dehumidified in the process, etc., it is discharged to the outside through the drainage hose 86. Therefore, the hot and humid air in the inner tank 30 is not directly discharged to the outside.

Now, in this dehydrating/drying/hidden washing machine, the inner tank 30 is composed of a pair of substantially hemispherical members 30a and 30b divided in the direction of its rotational axis (X-X), and their inner reinforcing ribs 46 are oriented horizontally. Since the outer reinforcing rib 47g) protrudes and has a horizontal portion 47a formed on the outer diameter side, the members 30a and 30b can be smoothly cut out and molded easily.

By joining these hemispherical members 30a and 30b to each other at their opposing edges, the spherical inner tank 30 can be easily manufactured. Further, since a plurality of inner reinforcing ribs 46 extending along the joining direction of both members 30a, 30b are integrally formed on the inner surface of the peripheral wall of both members 30a, 30b, sufficient strength of the inner tank 30 can be ensured. In addition, since a plurality of outer reinforcing ribs 47 are integrally formed on the outer surfaces of the peripheral walls of both members 30a and 30b, and extend along a direction perpendicular to the joining direction of both members 30a and 30b, the reinforcing ribs 47 , Inner W! 30 can be further increased and can withstand loads from all directions.

Furthermore, since the inner reinforcing rib 46 extends along the rotational axis direction of the inner tub 30, when the inner tub 30 is rotated around the horizontal axis aX-X and a washing operation or a drying operation is performed,
The inner reinforcing ribs 46 facilitate the transfer of the items to be washed, thereby enhancing the washing and drying effects. Also,
Particularly during the drying operation, a gap is formed by the inner reinforcing rib 46 between the inner surface of the peripheral wall of the inner tub 30 and the object to be washed, so that warm air flows through the gap as well, improving drying efficiency. Furthermore, since the outer reinforcing rib 47 extends along the direction perpendicular to the rotational axis of the inner tub 30, when the inner tub fJ30 is rotated around the horizontal axis XX and a washing operation is performed, the outer reinforcing rib 47 The reinforcing ribs 47 prevent the washing water from being stirred indiscriminately, and the generation of bubbles can be reduced.

[Another Embodiment] Next, another embodiment of the present invention will be described based on FIGS. 8 and 9.

In this embodiment, the inner reinforcing ribs 46 extend in the meridian direction along the rotational axis direction of the inner tank 30.

They are integrally formed on the inner surfaces of the circumferential walls of both members 30a and 30b at predetermined intervals so as to extend to. Further, as in the embodiment described above, the outer reinforcing ribs 47 are integrally formed concentrically at predetermined intervals on the outer surfaces of the peripheral walls of both members 30a and 30b so as to extend in a direction perpendicular to the rotational axis of the inner tank 30. There is. Therefore, in this embodiment as well, the inner reinforcing rib 46 and the outer reinforcing rib 47 work together to ensure sufficient strength of the inner [30], as in the previous embodiment.

[Modification] Note that the present invention is not limited to the configuration of the embodiment described above, and can be modified and embodied as follows.

(1) The inner tank 21 is formed into a substantially cylindrical shape using a wire mesh or the like, and the mesh on the peripheral wall is used as a drainage part, or a plurality of columns are combined to form a substantially cylindrical framework, and the gaps between each column are formed. Alternatively, a stainless steel plate or the like may be formed into a cylindrical shape with a bottom, and a drain hole may be provided through the peripheral wall and bottom wall.

(2) The inner tank 30 is rotatably supported around an inclined axis that is inclined at a predetermined angle with respect to the horizontal axis XX.

(3) Deleting the outer reinforcing claw ribs 47 of both members 30a and 30b of the inner tank 30.

[Effect of the invention] Since this invention is configured as explained above,
It is possible to easily manufacture a spherical inner tank, and the inner tank can be sufficiently strengthened with a simple reinforcing structure using inner reinforcing ribs. It has the excellent effect of promoting the transfer of the material, improving the washing effect, and further increasing the strength due to the outer reinforcing ribs.
