Abstract

PURPOSE:To prevent a cylindrical bellows extendable in an axial direction damaged or a connecting part to another path component separated or damaged by providing the bellows at the intermediate part of a hot air supply path, and arranging the axis of the bellows almost in parallel with one straight line intersecting orthogonally with the vertical axis of a supporting body. CONSTITUTION:The tip apertures of hot air supply tubes 120A, 120B, and 120C are connected from a fan case 111 to an introduction port 101 passing the side part, the upper part, and the side part of a main body case 1. The bellows 141 is formed cylindrically as the one extendable in the direction of axis A-A, and the axis A-A is located at a position with eccentricity in a radial direction from the vertical axis Z-Z of the supporting body, and is arranged almost in parallel with the one straight line intersecting orthogonally with the vertical axis Z-Z, and is formed as part of the hot air supply tubes 120A, 120B, and 120C. In such a way, since the bellows 141 absorbs the inertia forces of the supporting body 21 and an inner tub 30 generated by a control operation by a braking body 75 for the stoppage of a dehydration operation as being compressed, no separation from the connecting part of another supply tubes 120a, 120b occurs, and further, the damage of the bellows 141 can be prevented from occurring.

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 in the outer #e15 during rinsing.

(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 M4 and the inner tub lid 37 open, the laundry is put into the inner tub 30, 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 washing water level Wn that reaches the inside of the inner tank 30, the seed part movement motor 51 is rotated, and the inner tank 30 is moved back and forth via the inner tank rotation drive means. The washing operation is started by being rotated about the horizontal 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 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 3° 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).

Note that the water from the bubbles turned into water droplets on the filter 105 is transferred to the bubble guiding plate 1.
It is conducted through 03.

The fan case 111 is located outside the main body case 1! 1
A fan 113 having a wavy portion 112 on the outer periphery is rotatably supported inside the fan 113 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 131 is fixed to the outer surface of the fan case 111 in order to support one end of the horizontal shaft 114. Air passage hole 1

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.
is rotated.

When the fan 113 is rotated, the foam guide 104. Outlet 102. Bellows 116 and 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 port 102. The bellows 116 and the like constitute an exhaust passage for guiding moisture-containing air used for drying the laundry to the outside of the outer tub 15. Moreover, the fan case 111

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 spacing between the circumferential protrusions 126 and 128 is extremely narrow, which prevents the air inside and outside the fan 1]3 from mixing.

The guide portion 129 is formed on the guide member 127 to catch water droplets blown off by the rotation of the fan 113 and condensed from the humid air, and causes the water droplets to fall downward under their own weight. A drain pipe 130 made of a flexible member and constituting a discharge passage 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 drains the condensed water collected by the guide part 129. Drain hose 86

The hot air supply pipes 12OA, 120B, and 120C pass from the fan case 111 to the side and upper part of the main body case 1, and then through the side, and their tip openings are connected to the introduction port 101. As shown in FIG. 4, the bellows 141 has an axis line A-A.
It is a cylindrical body that is expandable and retractable in the direction, and its axis A-A is located at a position eccentric in the radial direction from the vertical axis Z-Z of the support, and is in a straight line (e.g. It is arranged substantially parallel to the horizontal axis Y-Y),
It is formed as a part of hot air supply pipes 120a, 120b, and 120c. A heater 142 serving as a heating means is provided inside the hot air supply pipe 12Oa and heats the air passing through the supply pipe 120a. Therefore, the air dehumidified within the fan case 111 is transferred to the heater 14.

A portion of the water is supplied into the outer tank 15. And inner tank 30
The warm air that has passed through the inner and outer tanks 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 setting 2・S 143, 144
is provided in the warm air passage portion of the fan case 111 to detect overheating of the warm air and stop the operation of the heater 142.

(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.

2 is rotated, the fan 113 of the dehumidifier is rotated, and the heater 142 is further heated.

Therefore, based on the intake air and centrifugal horn blowing by the rotation of the fan 113, air heated by the heater 142 is introduced into the inlet 101, the bubble guide port 1.04, and the inner tank shaft portion 31 via the hot air supply passage 120. The clothes that are fed into the inner tank 30 from the port 33 and stirred in the inner tank 30 are dried. As the fan 113 rotates, the high-temperature air in the inner tank 30 containing a large amount of moisture is discharged through the outlet 34 of the inner tank shaft, the foam outlet 104, the outlet 102, the bellows 116, and the suction port of the fan case 111. 115 into 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 the moisture contained therein is reduced to 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 connected to the hot air supply pipes 120a, 120b.

120C and is sent into the inner tank 30 from the inlet 101.33 to dry the clothes again. In addition, as shown in FIG. 4, the bellows 141 provided between the hot air supply passages 120a, 120b, and 120c absorbs vibrations and rocking of the outer Wj 15 that occur during washing, rinsing, spin-drying, and drying operations. At the same time, since it is formed into a cylindrical body that can be expanded and contracted in the direction of the axis (A-A), it can withstand the inertial force of the support body 21 and the inner tank 30 generated by the braking operation of the brake body 75 to stop the dewatering operation. Since the bellows 141 absorbs its inertial force while being compressed, the bellows 141 is prevented from being damaged without separating from the connection with the other supply pipes 120a and 120b.

As described above, in this spin drying washing machine, high temperature air is sent 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 almost no possibility that hot and humid air will leak out of the washing machine. In addition, hot air supply pipes 120a, 120b, 1
Vibration and rocking of the outer tank 15 by the bellows 141 of 20c,
Furthermore, since the inertial force of the support body 21 and the inner tank 30 is absorbed, vibrations and rocking are prevented from being transmitted to the dehumidifiers 111, 113, etc., the heating means 142, the main body case 1, etc.

[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. . In addition, the bellows, which is a part of the hot air supply pipe that supplies heated air to dry clothes, does not transmit the vibrations and rocking of the outer tank to the heating means or main body case, so it is effective in suppressing noise. It is highly effective, and because it is located in a position that absorbs the inertial force that occurs in the rotational braking force of the support and inner tank, it prevents the connection between the hot air supply pipe and the bellows from coming loose and the bellows from breaking. be done.
