Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a washing/drying machine that can perform washing, rinsing, spin-drying, and drying processes continuously.

2. Description of the Related Art Conventionally, a washer/dryer having a structure as shown in FIGS. 13 and 14 has been considered. That is, a water tank 2 is rotatably supported within the main body 1 of the washer/dryer by a horizontal shaft 3, and a rotary tank 4 is rotatably installed inside the water tank 2 via a rotary shaft 5. The lower part of the water tank 2 is equipped with a pulsator, a drive switching device 6 for the rotating tank 4, and a motor 7a for driving the rotating shaft 5. The rotating shaft 5 and the motor 7a are connected via a belt. A moving motor 7b is fixed to the main body 1 near the end of the horizontal shaft 3, and a pinion gear 9 that meshes with a worm gear 8 driven by the moving motor 7b is fixed to the horizontal shaft 3. When the worm gear 8 rotates, the pinion gear 9 is driven, and in response, the horizontal shaft 3 rotates, and the water tank 2 rotates around the horizontal shaft 3. A fan 10 used during drying is connected to a duct 12 via a heater 11 on the outside of the lower part of the water tank 2, and the duct 12 communicates with the inside of the water tank 2. 13 is a drain port.

In the above configuration, clothes are placed in the water tank 2 and the power is turned on. The washing, rinsing, and spin-drying steps are performed with the water tank 2 in the vertical position shown in the solid line in FIG. 13 and in FIG. Then, the water tank 2 is placed in a horizontal position and the drying process begins. This state is shown in FIG. 13 by a two-dot chain line. In the drying process, the rotary tank 4 is rotated, and the fan 0 and the heater 11 are energized to perform drying.

00 rpm, drying process special rotation at 60 rpm, 1.
This drive is performed by a motor 7a. If this operation is performed by controlling the motor 7a, an extremely complicated and expensive control device is required, and if this operation is realized by the drive switching device 6, the drive switching device 6 requires a plurality of clutches and a plurality of reduction gears. However, there is still the problem that the configuration is extremely complicated.

Furthermore, the water tank 2 is supported by a horizontal shaft 3 in order to turn the water tank 2 into a substantially horizontal state or a substantially vertical state. Because of this, when the water tank 2 is rotated, the trajectory of the drain port 13 becomes very large, making it impossible to secure a sufficient volume of the water tank 2 in the limited size of the main body 1, resulting in a small washing and drying capacity. There's a problem. In addition, in order to effectively utilize the space inside the main body 1, it is possible to arrange the horizontal shaft 3 at the corner of the main body 1, but in this case, the trajectory of the top and bottom of the cylindrical water tank 2 when it turns There is a problem in that the water tank 2 interferes with the side wall of the main body 1 and a sufficient volume of the water tank 2 cannot be secured.

Therefore, the first object of the present invention is to obtain a highly reliable rotating tank drive mechanism with a simple configuration.

The second purpose is to obtain a drain port configuration that can effectively utilize the volume within the main body.

The third purpose is to obtain a water tank configuration that can effectively utilize the volume within the main body.

Further, in order to achieve the third object, in the present invention, the pair of rotating shafts are provided at diagonal corners of the main body, and the water tank has a substantially cylindrical shape with a substantially truncated conical top and bottom.

Function: The washer/dryer of the present invention has the above-mentioned configuration, and uses separate motors to drive the rotary tubs during the spin-drying process and the drying process, respectively.
Further, the drying motor and the rotary tank are connected via a speed reduction device and a detachable clutch. Therefore, the drying motor can be made smaller and does not require a complicated control device.
It has a simple configuration and high reliability.

In addition, since the drain port is located near the corner of the main body when the water tank is approximately horizontal, the trajectory of the drain port during rotation will pass through the corner of the main body, reducing the volume inside the main body. It can be used effectively and the aquarium can be enlarged.Furthermore, since the upper part of the aquarium and the rfE part are approximately truncated conical, the trajectory of the aquarium during rotation is small and the aquarium can be enlarged.

Next, the operation in this embodiment will be explained. FIG. 1 shows the state of the water tank during the washing, rinsing, and spin-drying processes.

During the washing/rinsing process, the washing shaft 28 of the rotary tub 25 is positioned perpendicularly to the installation surface of the main body A14, and at this time, the pulsator 26 is connected to the washing shaft 28 via the mechanical part 27 and is driven by the washing motor 33. It rotates in a predetermined forward and reverse cycle.

During the washing process, the water tank is filled with water for washing, but the fifth
As shown in the figure, the water tank A 18A and the water tank 818B have a fitting configuration and are provided with a sealing material 19, so water does not leak out and reliability is extremely high. During the dehydration process, the rotary tank 25 is connected to the dehydration shaft 29 by the mechanical part 27 and rotates at a high speed of about 800 rpm to perform dehydration. At this time, the vibration of the rotating tank 25 is transmitted from the water tank A18A to the suspension 45 via the rotating shaft 43 and is attenuated. During the washing, rinsing, and spin-drying processes, the speed reducer 37 and the drying pulley 38 are disconnected from each other by a clutch 39. Therefore, the rotation of the washing motor 33 is not transmitted to the speed reducer 37 or the drying motor 36, and does not interfere with the driving of the pulsator 26 or the rotating tub 25.

When the dehydration process is completed and the drying process begins, the residual water detector 23 confirms that no water remains in the water tank A18A, that is, the resistance between the electrodes of the residual water detector 23 reaches a predetermined value. When it crosses the line, it performs a turning motion. As a result, under no circumstances will the water tank 18 be turned with water remaining in it (it is extremely reliable). The winding pulley 55, which is driven and attached to the rotation reduction mechanism output shaft 56, winds up the wire 58, and the water tank gradually rotates around the rotation shaft 43.The water tank becomes horizontal and the J Mitsutwitch is activated. The rotation motor 49 is stopped by the operation of B65.Then, the guide boo IJ A61 is moved by the tension of the wire 58 and releases the limit switch A64.In the above rotation, as shown in FIGS. 10 and 11, the water tank A18A
Since the bottom and top of the water tank 818B and the water tank 818B have a truncated conical shape, interference with the side wall of the main body A14 can be avoided, the inside of the main body A14 can be used effectively, and the volume of the water tank can be maximized. It becomes. Also the 11th
As shown in Fig. 12, the drain port 22 is located at the corner of the main body A14 when the water tank is in a horizontal state.
The trajectory of the drain port 22 during rotation passes through the corner of the main body A14, making it possible to effectively utilize the volume within the main body A14 and make the water tank thicker.

Next, in the drying process, the rotation clutch 50 is released and only the blower 47 is driven by the rotation motor 49. At the same time, the drying motor 36 is driven, and the speed reduction device 37 and the drying pulley 38 are connected by the clutch 39.

The rotation of the drying motor 36 is approximately 60 rpm due to the reduction gear device 37.
The torque is amplified while decelerating to m. This makes it possible to obtain large torque with a small motor, and low-speed rotation without the need for a complicated control device. The rotating tank 25 starts rotating at a predetermined rotation speed of about 60 rpm by the drying motor 36 via the belt B40, causing the clothes inside the rotating tub 25 to roll. Heater 6
The drying air heated in step 7 is blown into the rotating tank 25 to dry the clothes. The heater 67 is provided near the opening at the top of the water tank B18B, and the heated drying air is immediately blown into the rotary tank 25, so that very efficient drying can be achieved. Next, when the drying process is finished, the rotating tank 25 stops, the rotating clutch 50 is connected, the rotating motor 49 rotates in the opposite direction, and the wire 5 is wound around the winding pulley 55.
Send out 8. When the water tank 18 becomes vertical, the tension of the wire 58 becomes weaker and the guide pulley A60 is moved by the spring A62.
The rotation motor 49 returns to its original position, operates the limit switch A64, and stops the rotation motor 49. As mentioned above, a series of steps from washing to drying are performed.

Effects of the Invention As described above, the present invention includes a motor that drives a rotary tank during the dehydration process and a drying motor that drives the rotary tank during the drying process, and the drying motor and the rotary tank can be disconnected from the speed reduction device. The drying motor and rotary tank are connected via a clutch, and separate motors are used to drive the rotating tank during the dewatering process and the drying process, and the drying motor and rotating tank are connected via a speed reducer and a clutch that can be freely disconnected. ing. Therefore, the rotating tank can be easily rotated at high and low speeds.
The drying motor can be miniaturized, does not require a complicated control device, and can achieve high reliability with a simple configuration.

Further, in the present invention, the pair of rotation axes are provided at diagonal corners of the main body, and the drain port is located near the corner of the main body when the water tank is in a substantially horizontal state, so that the trajectory of the drain port during rotation is This allows the aquarium to pass through the corner of the main body, making effective use of the different types of fish inside the main body and making the aquarium larger.
