[Prior Art] Recently, the inventors of this application have invented a dehydrating/drying washing machine as described below. This dehydrating/drying washing machine has an outer tank that can contain water inside the case body, and an inner tank that can rotate around a vertical axis inside the outer tank.
The inner tub has a structure in which an inner tub for storing laundry is rotatably arranged around a horizontal axis.

The laundry is washed by rotating the inner tub around the horizontal axis while supplying water to the outer tub so that the water level reaches the inside of the inner tub containing the laundry.
It is designed to perform rinsing.

Further, after draining the water in the outer tub, the support body and the inner tub are rotated at high speed around the vertical axis, thereby dewatering the laundry.

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 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. Upon rotation about axis X-x, the washing operation begins.

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 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 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 X-X without using swirling water flow, so there is almost no twisting or tangling of the laundry, and the amount of water is reduced. 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 intermediate 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 inlet 101 and the outlet 102 are located on the left-right horizontal axis Y-Y that intersects horizontally with the longitudinal horizontal axis XX. It is transparently installed in the peripheral wall of the outer tank 15. Therefore, when both shaft parts 31 of the inner tank 30 are arranged on the left-right horizontal axis Y-Y, 14 of them
The inlet 33 and outlet 34 of 30 are the opening 10 of the outer tank 15.
1 and the outlet 102, respectively. In addition, outer tank 1
The opening 101 of No. 5 has a slightly smaller diameter than the inlet 33 of the inner tank 30, and the outlet 102 also has a slightly smaller diameter than the outlet 34. The foam guide plate 103 is fixed to the left and right inner surfaces of the outer tank 15 so as to extend downward, and is provided therein so as to face the opening 101 and the outlet port 102, respectively, and has the inlet port 33. A bubble guide port 104 having a larger diameter than the discharge port 34, the opening 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. The upper end and both left and right ends of the foam guiding plate 103 are hermetically fixed to the inner surface of the outer tank 15, and a space is formed between the foam guiding plate 103 and the outer tank 15 with only the lower end open. The open lower end thereof 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. 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 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 a fan case 1 for supporting one end of the horizontal shaft 114.
It is fixed to the outer surface of 11. Air passage hole 11
8.119 are transparently provided at the center and outer peripheral portions of the outer plate portion of the fan case 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 internal 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.

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 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 outlet 102 of the outlet 34, 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. 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 (this 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. 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 within the fan case 111 is heated by this heater 142 and is sent to the outer tank 15 side, and is fed to the opening 101.33.
Most of the water is supplied into the inner tank 30 and a part is supplied into the outer tank 15 through the opening 101. Then, the inside of the inner tank 30 and the outer tank 15
The warm air passing through the fan case 111 is discharged from the exhaust passage.
There, it is dehumidified and sent to the heater 142 again.

For this reason, the hot air supply pipe 120 between the heater 142 and the outer Wi 15 connects the hot air supply pipe 120, the inside of the inner tank 30 and the outer tank 15, the discharge passage, and the fan case 1.
The inside of 11 and the like constitute a circulation passage. Temperature sensors 143 and 144 are provided in the hot air passage portion of the fan case 111, detect heating of the hot air, and stop the operation of the heater 42.

[Drying Operation and Dehumidifying Operation] Now, during the drying operation, first, the drain valve 85 is opened and the water in the outer tank 15 is discharged. Then, as shown in FIG. 3, the inner tank 21 is slightly rotated, and the inlet 33 of the inner tank 30
The inlet port 33 and the outlet port 34 are located on the horizontal axis Y-Y in the left-right direction, and the inlet port 33 and the outlet port 34 are located in the opening 10 of the outer tank 15.
1 and the outlet 102, respectively. Then, the drain valve 85 is closed again, and the spring clutch 71 is released. In this state, the inner tank 30 is rotated along the horizontal axis Y- by the inner tank rotation drive means as the motor 51 rotates.
While being rotated around Y, the motor 122 is rotated, the fan 113 of the dehumidifying device is rotated, and the heater 142 is further heated.

Therefore, based on the intake air and centrifugal air blowing by the rotation of the fan 113, air heated by the heater 142 is fed into the inner tank 30 from the inlet 33 via the hot air supply passage 120, and Dry the clothes that are being agitated.

As the fan 113 rotates, high-temperature air containing a large amount of moisture in the inner tank 30 is sucked into the outlet 34 of the inner tank shaft, the foam outlet 104, the outlet 102, the bellows 116, and the fan case 111. There, the centrifugal force based on the rotation of the fan 113 sends it to the outer circumferential side. 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 causes the fan to
The air inside 13 is cooled, and the moisture contained therein is turned into water droplets.

Therefore, the air sucked from the inner tank 30 is dehumidified,
The dehumidified air is sent to the heater 142 where it is heated again, and sent through the hot air supply pipe 120 to the opening 101 and the inlet 33 into 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 discharged through the drain pipe 130.

Furthermore, when the drying operation is completed or interrupted, the inner tub 30 is positioned on the longitudinal horizontal axis X-X, and when the entrance/exit port 36 coincides with the opening 3 of the main body case 1, the rotation of the inner tub 30 is stopped, and the laundry is removed. It can be easily put in and taken out.

As described above, in this dehydrating/drying washing machine, high-temperature air is blown into the inner tank 30, and the hot and humid air after drying the clothes in the inner tank 30 is dehumidified. is heated again and sent into the inner tank 30. In other words,
Since the heated air is repeatedly dehumidified and reheated while being circulated, there is little chance of hot and humid air leaking out of the washing machine.

Further, as shown in FIG. 7(a), the inlet 33 of the inner tank 30
Since the diameter of the outlet port 34 is larger than the diameter of the opening 101 and the outlet port 102 of the outer tank 15, when heated air flows into the inner tank 30, almost all of it flows smoothly. There is almost no leakage into the outer tank 15 before the introduction port 33, and the air that flows into the inner tank 30 is diffused throughout the interior and used for drying clothes, and then a part of it is The air is discharged from the outlet 34, passes through the small holes 35, 27 of the inner tank 30 and the middle tank 21, and finally concentrates at the outlet 102, and the hot and humid air is sent to the fan 113 of the dehumidifier. Effectively absorbed.

Now, in order to smoothly discharge air from the outlet 102 of the outer tank 15, the applicant has changed the diameters of the opening 101 and the outlet 102 of the outer tank 15 to an inner diameter, as shown in FIG. Tank 3
An attempt was made to set the diameter to be larger than the diameter of the inlet 33 and outlet 34 of the outer tank 15.
When the air is introduced from the opening 101 into the inlet 33 of the inner tank 30, as shown in FIG. The heated air flows between the inner circumferential surface of the outer tub 15 and reaches the outlet 102 of the outer tub 15 without being used for drying the clothes, resulting in a waste of heated air and a decrease in drying efficiency.

However, this is not the case in this embodiment.

Note that this invention is not limited to the above embodiments,
It is also possible to embody it as follows.

(a) In the embodiment described above, the fan 113 serves both the functions of forming circulating airflow and condensing water, but this function may be performed by a separate device. For example, a normal fan is installed upstream of the heater, and piping through which cooling air passes is installed upstream of the fan, and after the hot air is cooled and dehumidified by the piping, it is sent to the heater side by the fan. To do.

(B) In the embodiment described above, the supply of warm air to the inside of the inner tank 30 and the suction of the warm air from inside the inner tank are mainly performed through the shaft of the inner tank 30, but at least one of the supply and the suction is performed. is configured to be performed through a small hole 35 in the peripheral wall of the inner tank 30. In this case, the positions of the opening 101 and the outlet 102 of the outer tank 15 may be changed.

(c) The rotation of the fan 113 is driven by the motor 5 for driving the inner tank.
1 and omit the motor 122.

(d) The inner tank 30 is supported rotatably around an inclined axis that is inclined with respect to the horizontal axis.

(E) A motor for selection and rinsing and a motor for dewatering should be installed separately.

(f) The filter 105 is provided on the warm air blowing side of the hot air supply pipe 120, slightly further inside.

[Effects of the Invention] As is clear from the detailed description above, according to the present invention, washing, rinsing, spin-drying, and drying can be sequentially and continuously performed with laundry stored in the inner tub, and in particular, During drying, high-temperature air does not flow out of the inner tank from the hot air supply passage and is blown straight into the inner tank, making it possible to effectively blow high-temperature air onto the laundry to be dried and heat it. The drying effect can be improved. In addition, the hot and humid air used for drying the laundry can be uniformly diffused into the inner tank, and can be introduced into each of the inner and outer tanks.

Since the outlet ports are arranged in series, the center of the air flow inside the inner tank is set in a straight line, and the entire air flows extremely smoothly along the center of the flow, and in this state, the air flows outside the outer tank. This can prevent hot and humid air from staying in the inner tank and hindering the drying of laundry.
