(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 31, and then the inner tank lid 37 and the main body opening/closing lid 4 are closed and the start switch (path shown) is turned on. When operated, a series of operations shown in the time chart of FIG. 3 are automatically performed sequentially by the control device (path shown). That is, (al Water supply operation by the water supply device 81 (b)
Washing operation based on the rotation of the inner tank 31 by the first drive mechanism 77 (draining operation (d) by opening the C1 drain valve 85) Second
Based on the rotation of the inner tank 21 by the drive mechanism 78 (dewatering operation tel Water supply operation by the water supply device 81 (f) Water supply by the water supply device 81 and inner tank 3 by the first drive mechanism 77
Rinse operation based on the rotation of the inner tank 21 by the second drive mechanism 78 (1) Warm air supply by the hot air supply device 95 and the first Based on the rotation of the inner tank 31 by the drive mechanism 77 (drying operation) During each of the above operations (al to (1)), the control device (the illustrated path) ) is used to position the middle tank 21 or the inner tank 31.

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 31,
The drain valve 85 is closed, the spring clutch 71 is placed in a disconnected state, the first drive mechanism 77 is formed, and the brake body 76 is placed in a braking state to restrict rotation of the inner tank 21. In this state, the water supply valve of the water supply device 81 is opened, water is supplied into the outer tank 15 from the first and second water supply ports 82 and 83, and the water level in the outer tank 15 reaches the inside of the inner tank 31. When the water level reaches the normal water level Wn, the seed section driving motor 51 is rotated in the normal direction, and the inner tank 31 is moved to the horizontal axis vA via the first drive mechanism 77.
Rotated around x − x. Then, the washing operation is started by the rotation of the inner tank 31.

During this washing operation, the spherical inner tank 31 containing the items to be washed is rotated around the horizontal axis vAx -x,
Along with the rotation, the object to be washed is rolled by the plurality of reversing protrusions 34, 40, etc., and so-called beating washing is performed.

Therefore, the amount of water used when washing can be reduced. In addition, since there are almost no twists or entanglements in the items to be washed, the washing operation can be carried out effectively without damaging the cloth, and at the end of the washing operation, any twists or entanglements in the items to be washed can be corrected. The washing operation can be automatically shifted to the draining operation and the dewatering operation without the need for such troublesome work.

In addition, when rinsing is performed after washing items,
In the same way as in the case of washing, the inner tank 31 is rotated by the seed part movement motor 51 via the first drive mechanism 77, and by opening the water supply valve of the water supply device 81, the inner tank is opened from the first water supply port 82. 31 , water is supplied from the second water supply port 83 into the inner tank 31 via the ventilation passage 99 , the ventilation port 101 and the rear shaft portion 32 , and the water inside the outer tank 15 is supplied with water. The rinsing water is discharged through the overflow port (path shown) and the overflow hose 87, and the water level is kept constant.Therefore, the rinsing water is replaced one after another, and the bubbles attached to the outer circumferential surface of the inner tank 31 are removed. The water from the first water supply port 82 washes away, and the water from the second water supply port 83 effectively washes away the bubbles adhering to the objects in the inner tank 31.

Furthermore, when dewatering is performed after the washing and rinsing of the laundry, the spring clutch 71 is brought into the connected state to form the second drive mechanism 78, and the brake body 76 is brought into the non-braking state to perform the intermediate operation. Rotation of the tank 21 is allowed. When the seed part driving motor 51 is rotated in the forward direction in this state, the inner tank 21 and the inner tank 31 are rotated integrally around the vertical axis Y-Y via the second drive mechanism 78, and the laundry is dehydrated. will be held.

Therefore, the rotational axis of the inner tank 31 containing objects can be changed from the horizontal axis XX to the vertical axis
By changing to -Y, it can be done smoothly in a short time.

Furthermore, when drying is performed after dehydrating the laundry, the inner tank 31 is rotated around the horizontal axis X-X by the seed section driving motor 51 via the first drive mechanism 77, as in the case of washing. At the same time, by energizing the fan motor 96 and the heating heater 98, hot air is generated from the hot air supply device 95, and the hot air flows through the connecting cylinder 100, the ventilation passage 99, and the rear shaft portion 32 to the inner tank. 31 and each small hole 35
is discharged from. Therefore, while transferring the items to be washed,
The drying operation can be performed effectively by applying warm air to the items to be washed. During the drying operation described above, the inner tank 31
The hot and humid air inside is introduced from the overflow port (shown in the diagram) that also serves as a hot air blower provided in the outer tank 15, through the overflow hose 87, into the expansion cooling chamber 88, where it is cooled and dehumidified, and then sent to the outside. It is discharged.

Next, regarding the filter for removing foreign matter, see Figures 1 and 4.
This will be explained in detail according to FIGS.

The inner tank 21 has a groove 111 extending vertically, and the inner tank 31
A cover 112 having a substantially U-shaped cross section with a side opening extending vertically.
is blocked by. And both 111, 112
A circulation waterway 113 is formed which is open at both the upper and lower ends. A lower opening 114 of the circulation waterway 113 is located close to the stirring rotor 63 and communicates with the pump chamber 63, and an upper opening 115 is located on the inner surface of the balancer 22. A pair of locking portions 116 facing each other are formed on the inner edge of the lower opening 115 .

The filter 117 includes a net-shaped filter body 118 and a frame 119 attached to the opening of the filter body 118. The locking portions 116 are provided on both outer surfaces of the frame 119.
A pair of locking pieces 120 that are removable are provided protrudingly from both sides 11.
6. When 120 is engaged, the frame 119 is inserted into the upper opening 115.
The filter 117 is removably held in the lower opening 115 with the filter main body 118 facing the upper outer periphery of the inner tank 31 .

Therefore, during the above-mentioned washing and rinsing operations,
The stirring rotary body 64 is rotated together with the upper rotating shaft 62. As it rotates, a small hole 27 formed in the bottom wall of the inner tank 21 and the support plate 23, a pump chamber 63, and a stirring rotor 64 are formed in the vicinity of the bottom of the outer tank 15 as shown by arrows in FIG. Through hole 67
A water flow is formed through the outer tank 15, and the water in the outer tank 15 is stirred.

Additionally, as the stirring rotor 64 rotates, the circulation waterway 113
A pumping water flow is formed in the filter 117, and foreign objects such as lint and buttons separated from the items to be washed are carried away by the filter 117.
The filter body 118 ensures that foreign objects are captured by the filter body 118. Furthermore, the pumped water flow after foreign matter removal is distributed from the filter 117 toward the outer periphery of the inner tank 31, thereby ensuring that bubbles adhering to the inner tank 31, especially during the washing operation, are dissipated.

During the rinsing operation, bubbles are more effectively dissipated by the water poured from the first water supply port 82 and the sprayed water.

Furthermore, when disposing of foreign matter accumulated in the filter body 118, first, with the washing machine stopped,
When the filter 117 is pulled toward the inner tank 31, the pair of locking pieces 120 engage with the locking portion 116 and are deflected inward against their own elasticity, and then pass between the measurement target upper portions 116 and engage. The stop portion 116 is separated outwardly, and the engagement between the two 116 and 120 is released. Therefore, the filter 117 can be easily removed from the inner tank 21.

When the filter 117 is to be reinstalled after discarding the foreign matter inside the filter body 118, the upper opening 115
Press the filter frame 119 toward the locking portion 116 of the
By engaging each of the locking pieces 120 with each of the locking portions 116, attachment of the filter 117 can be easily completed.
