The overflow hose 87 is connected between the overflow port (not shown) and the drain hose 86. The water overflow port is provided on the peripheral wall of the outer tank 15 and is configured to set the water level Wn in the outer tank 15.

(Requirements for operations other than drying operation and dehumidifying operation) Next, the essential operations of the dehydrating/drying washing machine configured as described above will be explained.

First, with the main body opening/closing 14 and the inner tub lid 37 open, the laundry is put into the inner tub 30, and then the inner tub lid 37 and the main body opening/closing lid 4 are closed and the start switch (path shown) is operated. Then, a series of operations are automatically performed in sequence under the control of the control circuit (path shown).

Now, when washing is performed with laundry stored in the inner tub 30, the drain valve 85 is closed and the spring clutch 71 is in a disconnected state, forming a driving means for rotating the inner tub. At the same time, the brake body 75 enters a braking state, and the rotation of the inner tank 21 is regulated. In this state, 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 normal water level Wn that reaches the inside of the inner tank 30, the seed part driving motor 51 is rotated, and the inner tank 30 is horizontally moved in the front-rear direction via the inner tank rotation drive means. The washing operation is started upon rotation about the axis X-x.

During this washing operation, the spherical inner tub 3 containing the laundry
While the laundry is being transferred by the plurality of reversing protrusions 40 as it rotates around the horizontal axis X-x in the longitudinal direction of 0,
So-called pound washing is performed.

Further, when rinsing is performed after washing the laundry, the inner tub 30 is rotated by the inner tub rotation driving means by the seed section driving motor 51, as in the case of washing. Also, water supply port 8
Water is supplied from 2 toward the outer circumferential upper surface of the inner tank 30, and the rinsing water in the outer tank 15 is supplied to the overflow port and the overflow hose 87.
The water level is maintained at a constant level. Therefore,
Rinsing is performed while the rinsing water is replaced in sequence.

As described above, washing and rinsing are performed by rotating the inner tub 30 around the horizontal axis aX-X without using swirling water flow, so there is almost no twisting or tangling of the laundry, and the water tank is Less is better. In addition, the inner tank 30
When is rotating on the longitudinal horizontal axis X-X,
The orientation of the entrance/exit 36 of the inner tub 30 and the lid 37 are the same as the orientation of the opening 3 of the main body case 1, and when the machine is stopped, they match, making it easy to take in and take out laundry.

Further, when the laundry is to be dehydrated after washing or rinsing the laundry, the spring clutch 71 is brought into a connected state, and the dewatering drive means is continuously connected to the inner tub rotation drive means.
The brake body 75 is brought into a non-braking state and the rotation of the inner tank 21 is allowed. In this state, when the seed part movement motor 51 is rotated, the inner tank 21 and the inner tank 30 are integrally moved along the vertical axis Z-
The laundry is rotated at high speed around Z to dehydrate the laundry.

Therefore, the transition from the washing or rinsing operation to the spin-drying operation can be performed by changing the rotational axis of the inner tub 30 containing the laundry from the horizontal axis X-X to the vertical axis Z-Z without changing the attitude of the tub.
This can be done by changing to . At the end of dehydration, the inner tank 21 stops when the entrance/exit 36 of the inner tank 30 and the opening 3 of the main body case 1 coincide.

In addition, between each of the above-mentioned operations, the stop positioning of the inner tank 21 or the inner tank 30 is performed by the control circuit (not shown) based on a detection signal from a sensor (not shown).

A space is formed between 03 and the outer tank 15, with only the lower end open, and the open lower end is located at the lower end of the outer tank 15. The filter 105 has eyes large enough to prevent the bubbles in the outer tank 15 from coming out, convert the bubbles into water droplets, and allow air to pass through. Note that the foam water that has been turned into water droplets on the filter 105 is conducted through the bubble boiling plate 103.

The fan case 111 has an outer tank 15 inside the main case 1.
A fan 113 having a corrugated portion 112 on its outer periphery is rotatably supported inside the fan 113 by a horizontal shaft 114, as shown in FIG. Suction port 115
is formed approximately in the center of the fan case 111 at a position facing the outlet port 102, and the suction port 1
A flexible cylindrical bellows 116 is interposed between the outer tank 15 and the fan case 111 so as to cover the space between the outer tank 15 and the outlet 102 . Note that the plate body 131 is attached to the fan case 1 in order to support one end of the horizontal shaft 114.
It is fixed to the outer surface of 11. Air passage hole 11

The hot air supply pipe 120 is connected to the upper outer periphery of the fan case 111. A pulley 121 is formed at the center of the fan 113. On the other hand, the motor 122 is fixed to the inner bottom surface of the main body case 1, and a pulley 123 is attached to its output shaft.A belt 124 is hung between the pulleys 123 and 121. be rotated.

Then, when this fan 113 is rotated, the bubbling lower port 104, the outlet port 102, the bellows 116 and the suction port 1
Humid air in the outer tank 15 and the inner tank 30 is sucked into the center of the fan 113 from the inner surface through the fan 113, and as the fan 113 rotates, centrifugal force causes it to move to the outer circumference of the fan 113. The air is sent into the hot air supply pipe 120. On the other hand, on the outer side of the fan 113 as well, air entering the case 1 from the vent 125 of the main case 1 is sucked into the fan case 111 through the air passage hole 118 and released from the air passage hole 119 on the outer circumferential side. Ru. Therefore, heat exchange is performed between the inner and outer sides of the fan 113,
When the air on the inner surface side is high temperature and contains a lot of moisture, the air is cooled and the moisture in the air condenses into water droplets, and the water droplets are transferred to the fan 1 as the fan 113 rotates.
It is thrown to the outer circumference side of 13. Therefore, the exhaust port 34, the outlet 102, the bellows 116, etc. constitute an exhaust passage for guiding the moisture-containing air used for drying the laundry to the outside of the outer tub 15. Moreover, the fan case 11
1. Fan 113. A dehumidifying means is configured to condense moisture in the air guided to the exhaust passage by the motor 122 or the like into water droplets.

A plurality of protrusions 126 are provided on the outer periphery of the fan 113.
It is formed concentrically with 3 at the center.

The annular guide member 127 is fixed to the outer circumference of the fan case 111, and a plurality of protrusions 128 are formed thereon, which are located between the protrusions 126 of the fan 113. and,
The distance between the protrusions 126 and 128 is extremely narrow, which prevents the air inside and outside the fan 113 from mixing.

The guide portion 129 is formed on the guide member 127, and receives water droplets blown away by the rotation of the fan 113 and extracted from the humid air, and allows the water droplets to fall downward under their own weight. Drain pipe 13 made of a flexible member and forming a discharge passage
0 is connected between the lower part of the fan case 111 and the upper side of the drain valve 85 of the drain hose 86, and the condensed water collected by the guide part 129 is discharged into the drain hose 86.

The hot air supply pipe 120 passes from the fan case 111 to the side and upper part of the main body case 1 and then through the side, and its tip opening is connected to the introduction port 101 . The bellows part 141 is formed in a part of the hot air supply pipe 120, and is adapted to absorb vibrations caused by vibrations of the outer tank 15, etc. in this part. The heater 142 as a heating means is connected to the hot air supply pipe 120
It is provided inside the upstream side of the supply pipe 120 and heats the air passing through the supply pipe 120. Therefore, the air dehumidified within the fan case 111 is heated by the heater 142 and is sent to the outer tank 15 side, and the air that has been dehumidified within the fan case 111 is heated by the heater 142 and sent to the outer tank 15 side.
Most of the water is fed into the inner tank 30 from 33 , and a part of it is fed into the outer tank 15 from the inlet 101 .

The warm air that has passed through the inner tank 30 and the outer tank 15 is guided from the discharge passage into the fan case 111, where it is dehumidified and sent to the heater 142 again. Therefore, the hot air supply pipe 120 between the heater 142 and the outer tank 15 allows the hot air supply passage to be connected to the inside of the warm air supply pipe 120, the inner tank 30 and the outer tank 15, the discharge passage, the inside of the phage case 111, etc. A circulation passage is constructed. temperature sensor 143,

[(I): Drying Operation and Dehumidification Operation] Now, during the drying operation, first, the drain valve 85 is opened and the water in the outer tank 15 is discharged. Then, the drain valve 85 is closed again, and the inner tank 21 is slightly rotated so that the shaft 31 of the inner tank 30 is located on the left-right horizontal axis Y-Y, and the shaft 31 of the outer tank 15 is positioned on the horizontal axis Y-Y. They face the inlet 101 and the outlet 102, respectively. In this state, the inner tank rotation drive means rotates the inner tank 30 around the horizontal axis Y-Y as the motor 51 rotates, and
22 is rotated, the fan 113 of the dehumidifier is rotated,
The heater 142 roughly operates to heat up.

Therefore, based on the intake air and centrifugal force blowing by the rotation of the fan 113, the air heated by the heater 142 is passed through the hot water supply passage 120 to the inlet 101, the lower foaming port 104, and the inlet 33 of the inner tank shaft portion 31. The clothes that are fed into the inner tank 30 and stirred in the inner tank 30 are dried. The high-temperature air in the inner tank 30 that gets stuck in the rotation of the fan 113 and contains a large amount of moisture is discharged through the outlet 34 of the inner tank shaft and the lower bubble boiling port 1.
04, the air is sucked into the fan case 111 through the outlet 102, the bellows 116, and the suction port 115 of the fan case 111, where it is sent to the outer circumferential side by centrifugal force based on the rotation of the fan 113. At this time, an air flow is also formed on the outer surface of the fan 113 from the center to the outer periphery, and this air flow from the outside cools the air inside the fan 113, causing moisture contained therein to drop into water droplets. be converted into Therefore, the air sucked from the inner tank 30 is dehumidified, and the dehumidified air is sent to the heater 142 where it is heated again and passes through the hot air supply pipe 120 to the inlet 101.33.
The clothes are then sent to the inner tank 30 to dry the clothes again. Note that the condensed moisture is collected at the lower part of the fan case 111 and passed through the drain 12130 to the drain valve 85 of the drain hose 86.
Although the water is stored on the upstream side, the drain valve 85 is temporarily opened at appropriate time intervals to discharge the stored water.

As mentioned above, in this dehydrating/drying washing machine, the outer tub 1
Washing and rinsing can be performed by rotating the inner tub 30 around the horizontal axis with washing water stored in the tub 5. Also, with the washing water in the outer tank 15 drained, the inner tank 3
