(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)

During each of the above operations fal to (1), the drying operation is performed based on the rotation of the inner tank 31 by the drive mechanism 77. A detected object 126, which will be described later, is placed in the outer tank 1.
Detecting objects 103 and 128 of the Hall element section arranged on 5
By this detection, the positioning of the inner tank 21 or the inner tank 31 is performed by the control device (path 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 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 forward direction, and the inner tank 31 is moved along the horizontal axis X via the first drive mechanism 77.
- Rotated around 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 X-X, and along with the rotation, the items to be washed are transferred by the plurality of reversing ridges 34, so that the so-called Washing is done by beating. Therefore, the amount of water used when washing can be reduced. In addition, since there is almost no twisting or tangles in the items to be washed, the washing operation can be carried out effectively without damaging the cloth, and there is no need to worry about the troublesome task of correcting the kinks and tangles of the items to be washed at the end of the washing operation. □It is possible to automatically shift from washing operation to draining operation and dewatering operation without requiring any work.

In addition, when rinsing is performed after washing items,
Similarly to the above-mentioned 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 31 is drained from the first water supply port 82. Water is supplied toward the outer circumferential surface, and water is also 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 rinsing water in the outer tank 15 is The water is discharged through the overflow port (path shown) and the overflow hose 87, and the water level is maintained constant. Therefore, the rinsing water is replaced one after another, the bubbles adhering to the outer peripheral surface of the inner tank 31 are washed away by the water from the first water supply port 82, and the bubbles adhering to the items to be washed in the inner tank 31 are washed away by the water from the first water supply port 82. It is effectively washed away by water from the second water supply port 83.

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 forward 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 washing material is rotated around the vertical axis Y-'Y. is dehydrated.

Therefore, the rotational axis of the inner tank 31 containing the items to be washed can be changed from the horizontal axis XX to the vertical axis Y- without changing the attitude of the tank in order to transition from the washing or rinsing operation to the spin-drying operation.
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 rolling 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, the lid 37 of the inner tank 31 will be explained in detail. A pair of bearings 111 for supporting the lid body 37 have a square hole shape, and are located above the horizontal axis XX of the inner tank 31, and
It is located forward of the vertical axis YY of the inner tank 21 and is formed on an axis ZZ perpendicular to both axes. Each bearing 111 is located offset forward with respect to the joining line L of the pair of hemispherical members 31a and 31b forming the inner tank 31.

The lid body 37 is made of synthetic resin, connects a pair of rotating arms 112 located inside the inner tank 31, and both arms 112, opens and closes the entrance/exit 36 at its outer periphery, and closes the entrance/exit when the entrance/exit is closed. An opening/closing part 113 that can be engaged with the inner circumferential surface of the opening/closing part 113 is provided. And each rotating arm 11
By inserting the ring-shaped shaft support 114 formed at the free end of 2 into each of the bearings 111, the lid body 37 is attached to the inner tank 3.

The locking member 119 is disposed in the recess 115 leaving a gap for finger insertion, and a pair of shaft support pieces 1 formed at the center of the back surface of the locking member 119 are provided.
20 is engaged with the support shaft 118 from above. A stopper 121 is fitted to the support shaft 118 between one of the shaft support pieces 120 and the collar 117, thereby preventing the support shaft 118 from being removed. Also, the spring hook piece 122 is the recess 11
5, the back surface of the locking member 119 and the support shaft 11
8 and between the pair of shaft supporting pieces 120, the locking member 119 is held in the recess 115 by the leaf spring 123 locked to the piece 122, and the locking member 119 is held in the recess 115, as shown in FIG. is biased to rotate counterclockwise.

The locking protrusion 124 is formed at one end of the locking member 119, and when the locking protrusion 124 is engaged with a locking recess 125 formed at the periphery of the entrance/exit 36 of the lid 37, the lid 37
is held in the closed position shown in FIG.

The detected object 126 made of a rod-shaped magnet is attached to the lid 37
It is inserted and fixed from below into a housing part 127 made of a magnetically permeable synthetic resin material and formed protrudingly from the center of the rear edge. On the other hand, a detection body 128 for detecting the open/closed state of the lid body 37 is constituted by a Hall element, and is disposed above the driven gear 44 of the inner tank 31 at the periphery of the opening 17 of the outer tank 15.

Then, when the rotation of the inner tank 31 is stopped and the lid body 37 is placed in the closed position with the inlet/outlet 36 being placed opposite the opening 17, the object to be detected 126 is placed opposite the detection object 128, and the object to be detected 126 is A predetermined electrical signal is output from the body 128.

A pair of protrusions 129 are formed on the inner surface of the inner tank 31 and are located on both sides of the accommodating part 127 along the moving path of the accommodating part 127. When the lid body 37 is opened and closed, the accommodating part 1
27 is moved. A storage recess 130 for storing detergent is formed on the upper surface of the opening/closing part 113 of the lid 37, and when the lid 37 is rotated from the closed position to the open position, the detergent is introduced into the inner tank 31 from the storage recess 130. . Furthermore, each of the rotating arms 112 has a plurality of ribs 131 extending parallel to its longitudinal direction.

The detected object 126 of the lid body 37 is the detected object 128 on the outer tank 15.
are placed facing each other. Therefore, after placing the main body opening/closing lid 4 in the open position, insert your finger into the recess 115 of the lid body 37,
When the locking member 119 is rotated clockwise in FIGS. 1 and 5 against the biasing force of the leaf spring 123, the locking member 11
The locking protrusion 124 of No. 9 is removed from the locking recess 125 of the lid body 37.

Then, with the locking member 119 held at the rotation operation position, the entire lid 37 is rotated in the counterclockwise direction in FIGS. When the operating force is released, the locking member 119 is placed at the position shown in two-dot chain line in FIG. 5 by the biasing force of the leaf spring 123. Subsequently, when the lid body 37 is rotated to the open position shown in FIG. 6, the entrance/exit 36 is opened, and items to be washed can be thrown into the inner tank 31 through the entrance/exit 36. Further, if the detergent is stored in the storage recess 130 prior to the opening operation of the lid 37, the detergent can be easily poured into the inner tank 31 as the lid 37 is opened.

Thereafter, when the lid body 37 is rotated back toward the closed position shown in FIG. 5, the inner tank 31

In this state, when the lid body 37 is further rotated toward the closed position, the locking protrusion 124 of the locking member 119 is engaged with the locking recess 125 of the inner tank 31, as shown by the solid line in the figure. The lid 37 is held in the closed position.

On the other hand, when the lid body 37 is placed in the normal closed position shown in FIG. 5, the detected object 126 is placed opposite the detected object 128, as described above. Also, the lid body 37 is shown in FIG.
When the detection object 126 is slightly opened toward the open position as shown by the dotted chain line, the detection object 126 moves out of the detection range by the detection object 128.

Therefore, if the presence or absence of an output from the detection body 128 is monitored by a control device (not shown), the rotation of the inner tank 31 can be started after confirming the closed state of the lid 37, and the lid 37 can be incompletely closed. Since the inner tank 31 is not rotated in the same state, it can be used safely.

Furthermore, when the egg driving motor 51 is stopped and the inner tank 31 is stopped after inertial rotation at the end of the washing operation, the rinsing operation, and the drying operation, the inner tank 31 is rotated at a low speed by the egg driving motor 51. . In this rotating state, the detecting body 128 detects the detecting body 126, and when the detecting body 126 faces the detecting body 128 and a predetermined electric signal is output from the detecting body 128, the incubating egg is The rotation motor 51 is stopped, and the rotation of the inner tank 31 is stopped so that the lid body 37 faces the opening 17 of the outer tank 15.

Therefore, in this embodiment, the rotational position of the inner tank 31 can be detected by using the means for detecting the open/closed state of the lid body 37, and the number of parts required for these detection operations can be reduced. It can be manufactured at low cost.
