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.

(Overview of operations excluding drying operation and dehumidification operation) Next, an overview of the operation of the dehydrating/drying washing machine configured as described above will be explained.

First, with the main body opening/closing lid 4 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 turned on. When operated, a series of operations are automatically performed in sequence under the control of a 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 5 water level Wn, which is the inside of the inner tank 30, the seed part driving motor 51 is rotated, and the inner tank 3o is rotated in the front-rear direction via the inner tank rotation drive means. Upon rotation about the horizontal axis X-X, the washing operation begins.

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

Further, when rinsing is performed after washing the laundry, the inner tub 3o 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 about the horizontal axis X-X without using swirling water flow, so there is almost no twisting or tangling of the laundry, and The amount of water may be small. Note that when the inner tank 30 is rotating on the longitudinal horizontal axis X-X, the orientation of the entrance/exit 36 and the lid body 37 of the inner tank 30 is the same as the orientation of the opening 3 of the main body case 1, and when the inner tank 30 is stopped, They match, making it easy to put 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 this time, in the drying process described later, the hot air exhaust passages 1.02, 1
Since lint released from the laundry adheres to the filter 105 installed in the warm air supply passage 120, etc., and accumulates therein, water is supplied by the water supply means 82 etc. at the initial stage of dehydration. It is dispersed by the centrifugal force of the inner tank 30 and filtered through the net filter 105.
By causing water to collide with the net filter surface, the lint accumulated on the net filter surface can be peeled off and washed away at the same time, and the lint that has been peeled off and washed away is prevented from scattering and adhering to the outer tank 15. Therefore, by arranging the guide ribs 106 around the net filter 105 in the outer tank 15, it is possible to reliably guide the water to the drain port 84. At the end of dehydration, the inner tank 21 is connected to the inner 1130 entrance 36 and the main body case 1.
It stops when it coincides with the opening 3 of.

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 (path shown) based on a detection signal from a sensor (not shown).

(Related configuration of dehumidifying device and heating means) As shown in FIGS. 1 and 4, the inlets 101 and 8 and the outlet 102 are connected to the left-right horizontal axis Y-X, which intersects horizontally with the longitudinal horizontal axis X-X. It is transparently installed in the peripheral wall of the outer tank 15 on Y. Therefore, both shaft portions 31 of the inner tank 30
When the inner tank 30 is placed on the left-right horizontal axis Y-Y, the inlet 33 and the outlet 34 of the inner tank 30 face the inlet 101 and the outlet 102 of the outer tank 15, respectively. Note that the inlet 101 of the outer tank 15 is the inner Ill! ! It has a slightly smaller diameter than the inlet port 33 of I30. The foam guiding plate 103 is the outer tank 1
fixed to the left and right inner surfaces of 5 so as to extend downwardly, facing the inlet 101 and the outlet 102, respectively;
Said introduction port 33. A bubble guide port 104 having a larger diameter than the discharge port 34, the inlet port 101, and the outlet port 102 is provided through the bubble guide port 104, and a filter 105 made of a fine mesh body is adjusted in both the bubble guide ports 104. Furthermore, guide ribs 106 are provided around the filter 105 to prevent lint from scattering.

The upper end and both left and right ends of the foam guiding plate 103 are connected to the outer tank 1.
A space 9 is formed between the foam guide plate 103 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. are doing. 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. It should be noted that the water from the bubbles formed into water droplets on the filter 105 is guided through the bubble guiding plate 103.

The fan case 111 has an outer tank 15 inside the main case 1.
A fan 1.13 having a corrugated portion 112 on its outer periphery is rotatably supported inside the fan 1.13 by a horizontal shaft 114, as shown in FIG. Suction port 11
5 is formed approximately in the center of the fan case 111 at a position facing the outlet 102, and an outer tank 15 is formed so as to cover the space between the suction port 115 and the outlet 102.
A flexible cylindrical bellows 116 is interposed between the fan case 111 and the fan case 111 . Note that the plate body 131 is fixed to the outer surface of the fan case 111 for supporting one end of the horizontal shaft 114. Air passage hole 1
．． Reference numerals 18 and 119 are transparently provided at the center and outer peripheral portions of the outer plate portion of the fan 111, respectively. 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.
, 121, a belt 124 is hung between them, and a fan 13 is rotated by this motor 122.

When the fan 113 is rotated, the bubble introduction 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 surface side of the fan 113, air that enters the case l from the vent hole 125 of the main body case 1 is sucked into the fan case 111 through the air passage hole 118 and is released from the air passage hole 119 on the outer circumferential side. 1. Therefore, heat exchange is performed between the inner and outer sides of the fan 113, and if the air on the inner side is high temperature and contains a lot of moisture, that air is cooled and the moisture in the air condenses. The water droplets are turned into water droplets, and the water droplets are blown toward the outer circumferential side of the fan 113 as the fan 113 rotates. Therefore,
The air containing moisture used for drying the laundry is transferred to the outer tank 15 through the outlet 34, the bellows 116, etc.
An exhaust passage is configured to guide the air to the outside. Further, the fan case 111. Fan 113. A dehumidifying means is configured that is guided to the exhaust passage by a motor 122 or the like and condenses moisture in the air 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.

2. 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. A heater 142 serving as a heating means is provided inside the hot air supply pipe 120 on the upstream side and heats the air passing through the supply pipe 120. Therefore, the air dehumidified in the fan case 111 is heated by the heater 142 and sent to the outer tank 15 side, and most of the air flows into the inner tank 3o from the inlet 101.33 and from the inlet 101. A portion is supplied into the outer tank 15.

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 hot air supply pipe 120, the inner tank 30 and the outer tank 15, the discharge passage, the inside of the fan case 111, etc. A circulation passage is constituted by each. Temperature sensor 1
43 and 144 are provided in the hot air passage portion of the fan case 111 to detect heating of the hot air and stop the operation of the heater 42.

[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. 4 are opposed to the inlet 101 and the outlet 102, respectively. In this state, the inner tank rotation driving means rotates the inner tank 3o along the horizontal axis I- as the motor 51 rotates.
At the same time, the motor 122 is rotated, the fan 113 of the dehumidifying device is rotated, and the heater 142 is heated.

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 air supply passage 120 to the inlet 101, the foam guide 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 3o are dried. As the fan 113 rotates, the high-temperature air in the inner tank 30 and the air containing a large amount of moisture are discharged through the outlet 34 of the inner tank shaft and the foam introduction 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 from the center to the outer circumference is also formed on the outer surface of the fan 113, and this air flow from the outside cools the air inside the fan 113 and removes the moisture contained therein. Becomes water droplets. 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 20 from the inlet 101.33 to the inner tank. 30, and the clothes are dried again. Note that the condensed moisture is collected at the lower part of the fan case 111 and stored upstream of the drain valve 85 of the drain hose 86 through the drain pipe 130, but the drain valve 85 is temporarily opened at appropriate time intervals. , and drain the accumulated moisture.

As mentioned above, in this dehydrating/drying washing machine, the outer tub 15
Washing and rinsing can be carried out by rotating the inner tub 30 around a horizontal axis with washing water stored therein. Also, with the washing water in the outer tank 15 drained, the inner tank 30
The laundry in the inner tub 30 is dried by rotating it around the horizontal axis and activating a dehumidifying device such as the fan 113 and the heater 142 to form a high-temperature circulating airflow passing through the inner tub 30. be exposed. Detergent foam is generated during washing and at the beginning of 6. rinsing. This bubble tries to come out from the bubble guide port 104, but it adheres to the filter 105 of the bubble guide port 104, is destroyed, and is guided downward through the bubble guide plate 103. Therefore, the bubbles may enter deep into the hot air supply pipe 120 and cause the heater 142 to short-circuit or the fan 1
13 can be prevented from interfering with the rotation thereof.

Note that during hot air circulation, the filter 105 allows the warm air to pass through.

At that time, the lint separated from the laundry and attached to the surface of the filter 105 is removed from the surface of the filter 105 by using the water scattering force by performing the water supply and dehydration operation at the beginning of dehydration, and is washed away and secured by the guide ribs. can be led to the drain port 84.

[Effects of the Invention] As is clear from the above detailed description, according to the present invention, the foam generated during washing is blocked by the filter, so there is no adverse effect due to the foam. In addition, it is possible to efficiently dry laundry by supplying hot air smoothly into the inner tub, and even if the lint that comes out during drying is attached to the net surface, the dehydration effect for the next washing operation will be improved. It can be removed reliably and washed away at the same time by splashing water. Further, the guide ribs can reliably guide the separated lint to the drain port side.
