(Operation) Next, an outline of the operation of the dehydration drying method constructed 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, then the inner tub lid 37 and the main body opening/closing lid 4 are closed, and a start switch (not shown) is operated. Then, under the control of the control circuit 111, a series of operations shown in the time chart of FIG. 6 are automatically performed in sequence as follows.

(a) Water supply operation by the water supply device 81 (b) Washing operation based on the rotation of the inner tank 30 by the washing drive means 76 (c) Drainage operation by opening the drain valve 85 (d)
Dewatering operation based on the rotation of the inner tank 21 by the dewatering drive means 77 (e) Water supply operation by the water supply device 81 (f) Water supply by the water supply device 81 and rinsing operation based on the rotation of the inner tank 30 by the washing drive means 76 (g ) Drainage operation by opening the drain valve 85 (h)
Dewatering operation (i) based on the rotation of the inner tank 21 by the dewatering drive means 77 Drying operation based on the warm air supply by the warm air supply device 94 and the rotation of the inner tank 30 by the washing drive means 76 Between a) and (i), the control circuit 111 determines the stop position of the inner tank 21 or the inner tank 30 based on a detection signal from a sensor (not shown).

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 inner tank 30, the drain valve 85 is closed, the spring clutch 71 is disengaged, and the washing driving means 76 is formed. The brake body 75 enters a braking state and the rotation of the inner tank 21 is regulated. In this state, the water supply device 81
The water supply valve 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 driving motor 51 is rotated, and the washing drive means 76 causes the inner tank to
0 is rotated at a reduced speed around the horizontal axis XX, and the 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 and 40. While washing, so-called washing is performed. Therefore, the amount of water used when washing can be reduced. In addition, since there is almost no twisting or entanglement of the items to be washed, the washing operation can be carried out effectively without causing any damage to the items to be washed.
To automatically shift from a washing operation to a draining operation and a dewatering operation without requiring the troublesome work of correcting twists and entanglements of items to be washed.

In addition, when rinsing is performed after washing items,
As in the case of washing, the inner tank 30 is rotated by the seed part movement motor 51 via the washing drive means 76. 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 at a constant level. Therefore, while the rinsing water is replaced in sequence, the water from the water supply port 82 effectively washes away the bubbles adhering to the outer peripheral surface of the inner tank 30 and the objects to be washed in the inner tank 30. .

Furthermore, when dewatering is performed after the washing or rinsing of the laundry, the spring clutch 71 is brought into a continuous state to form a dewatering drive means 77, and the brake body 7
5 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 rotary drive shaft 58 and the upper and lower hollow shafts 24.54 are rotated integrally,
Therefore, while the inner tank 30 is kept fixed to the inner tank 21, the dewatering drive means 77 moves the inner tank 21 and the inner tank 30 together.
are rotated together at high speed around the vertical axis Y-Y,
The items to be washed are dehydrated. Therefore, the rotational axis of the inner tank 30 containing the items to be washed is changed from the horizontal axis X-X to the vertical axis Y-Y during the transition from the washing or rinsing operation to the dewatering operation without changing the attitude of the tank. This allows the process to be carried out smoothly and in a short period of time. During this dehydration, the inner tub 30 is not rotated by the rotary drive shaft 58 through the meshing of the drive gear 69 and the driven gear 44, so the inner tub 30 does not move by itself. Therefore,
For example, as shown in FIG. 2, if the center of weight B of the object to be washed in the inner tub 30 is deviated from the vertical axis Y-Y, a centrifugal force acts on the object to be washed in the direction in which it deviates, and the center of weight of the object to be washed in the inner tub 30 is 30 rotates as shown by arrow A, and the items to be washed move toward the side wall.
As a result, unbalance occurs and large vibrations occur, but since the inner tank 30 is prevented from moving inadvertently as described above, this can be prevented.

In addition, when drying is performed after the dehydration of the items to be washed, the inner tank 3 is
0 is rotated around the horizontal axis X-X, and the fan motor 96 and heating heater 98 are energized to generate warm air from the hot air source 95 of the hot air supply device 94. Connecting cylindrical body 1001 hot air supply passage 99, air outlet 1
01 and the rear shaft portion 31 into the inner tank 30, and is discharged from each small hole 35. Therefore, the drying operation can be effectively performed by blowing warm air onto the items to be washed while rolling the items.

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. Therefore, the hot and humid air in the inner tank 30 is not directly discharged to the outside.

Note that the reduction ratio of the gear transmission system of this example is as follows. The rotation speed of the motor 51 is 1800 rpm, which is reduced to 900 rpm between the pulleys 5B and 61.
Next, with hypoid gear 63°68, 180r of 1/5
pm and further gear 69.44 to 3/6
Dropped to Qrpm.

As described above, in the dehydrating/drying machine of this embodiment, by switching the switching mechanism 80, the rotation of the inner tank 30 during the washing operation and the drying operation, and the rotation of the inner tank 21 and the inner tank 30 during the dewatering operation are controlled. This high-speed rotation can be achieved based on the rotation of one seed part movement motor 51.

In particular, in the embodiment, the rotational drive transmission unit 70
Since the parts are supplied in a factory, the contact between the teeth of the hypoid gear 68 and pinion 58 can be attached before assembly into the main body, and the accuracy of the combination can be adjusted in the state of the parts, which eliminates abnormal noise from the gears. It is possible to prevent the occurrence of

Further, in assembling the drive section, it is only necessary to insert the rotary drive transmission unit 70 from the upper part of the support body 21 and fix it to the support plate 23 with the screws 45, making the assembly very easy.

[Modifications] 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) Using a worm instead of the pinion 63 and a worm wheel instead of the hypoid gear 68.

In this case as well, the same effect as in the previous embodiment can be obtained.

[Effects of the Invention] As is clear from the detailed description above, according to the present invention, by supplying parts using the rotation transmission unit, adjustment for making contact between gears with staggered shafts can be made before assembly into the main body. In addition, since the accuracy of the combination can be adjusted in the unit state, it is possible to prevent the generation of abnormal noise from the gears. Furthermore, there is an excellent effect that the drive section can be easily assembled.
