Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washer / dryer capable of performing a series of steps from washing / rinsing / dehydration to drying.

[0002]

2. Description of the Related Art A washing / drying machine having a structure as shown in FIGS. 4 and 5 is considered. That is, a water tub 2 in the washing machine main body 1 is rotatably supported on a horizontal shaft 3, and a rotary tub 4 is rotatably mounted in the water tub 2 via a rotary shaft 5. A motor 7a for transmitting the driving force to the rotary shaft 5 via a belt 6 is provided below the water tank 2. A moving motor 7b is provided near the end of the horizontal shaft 3.
Is fixed to the main body 1, and a pinion gear 9 that meshes with a worm gear 8 driven by a moving motor 7b is fixed to the horizontal shaft 3. When the worm gear 8 is driven, the horizontal shaft 3 rotates accordingly, and the water tank 2 rotates around the horizontal shaft 3 as a center of rotation. Outside the lower part of the aquarium 2,
A fan 10 used during drying is connected to a duct 12 via a heater 11, and the duct 12 communicates with the inside of the water tank 2.

In the above structure, the washing, rinsing and dehydration steps are performed in the vertical state of the water tank 2 shown by the solid line in FIG. 5, and when the dehydration step is completed, the worm gear 8 is rotated by the rotation of the moving motor 7b, that is, the rotation of the pinion gear 9. Is driven,
The water tank 2 is placed in a horizontal posture, and the drying process is started. This state is shown by a two-dot chain line in FIG. In the drying process, the rotary tank 4 is rotated, the clothes are lifted and dropped, and the fan 10 and the heater 11 are energized to dry them.

[0004]

In the washer / dryer having the above-mentioned structure, the amount of clothes that can be dried is about 1/2 of the amount of clothes that can be washed, rinsed, and dehydrated due to the volume of the rotary tub. , If the amount of clothes is more than this, the drying time will be longer,
Drying unevenness and wrinkles will be severe. Therefore, at the start of washing, the user needs to judge whether the washing, rinsing, and dehydrating steps can be completed or the drying step can be performed according to the amount of clothes, which is very inconvenient.

Further, since this washer / dryer has all the steps of washing, dehydration, and drying, it is possible to operate in each independent step. Therefore, it is possible to operate only the drying process, not the drying after the dehydration process.If water remains in the water tank at this time, the water leaks out of the tank because the water tank is horizontal during the drying process. There was a problem with reliability.

The present invention has solved the above-mentioned conventional problems, and an object thereof is to obtain high reliability without water leakage under any operating condition.

[0007]

In order to achieve the above object, the present invention has a control device for performing a washing / rinsing / dewatering process in a substantially vertical state and a drying process in a substantially horizontal state of a water tank. The dehydration operation is performed by the device before driving the reversing device.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The washing machine of the present invention performs a dehydration operation before driving the reversing device, so that even if water remains in the aquarium before reversing, water may leak due to dehydration in the aquarium. It is possible to obtain high reliability.

Reference numeral 50 is a control device, which is a washing motor 23.
The mechanical unit 21, the drying motor 27, the drive motor 35, the heater 44, etc. are controlled. Reference numeral 51 is a cloth amount detecting means connected to the control device 50. In this embodiment, when the washing motor 23 drives the pulsator 19 during the washing process, the motor current value changes depending on the amount of clothes. There is. That is, water is supplied to a low water level, the pulsator 19 is driven, the current value of the washing motor 23 at this time is measured, and the amount of clothes is determined. Thereafter, additional water is supplied according to the amount of the clothes, and washing is started.

Next, the operation of this embodiment will be described. FIG. 1 shows the state of the water tank 15 during the washing, rinsing, and dehydration processes. The rotary shaft 20 of the rotary tank 18 is positioned vertically to the installation surface of the main body, and the pulsator 19 is moved by the mechanical section 21. Washing motor 23 connected to rotating shaft 20
It rotates in a constant cycle. At this time, the cloth amount detecting means 51 determines the amount of clothes as described above. The amount of clothes that can be dried is about ½ of the amount of clothes that can be washed, and if the washable amount is 4 kg, the amount of clothes that can be dried is 2 kg. Therefore, when the amount of clothes is detected to be a predetermined amount or more, that is, 2 Kg or more, the control device 50 finishes only the washing / rinsing / dewatering process, and notifies the user of the completion of washing (steps 1 to 5 in FIG. 3). . If you want to dry, take out some clothes and dry. When the amount of laundry clothes is less than or equal to a predetermined amount, that is, 2 Kg or less, the washing / rinsing / dewatering process is followed by the drying process to notify the completion of drying (steps 4, 6 to 9 in FIG. 3).

Here, the rotary tank 18 is connected to the rotary shaft 20 by the mechanical portion 21 like the pulsator 19 and is rotated at a high speed to perform a dehydration process. At this time, the vibration of the rotating tank 18 is caused by the suspension of the two suspensions 3 from the water tank 15 through the support columns 29.
It is transmitted to 1 and attenuated. When the amount of clothes is less than a predetermined amount after the washing / rinsing / dehydration process is completed, the clutch 36 is engaged and the drive motor 35 is driven for a certain period of time, and the winding pulley attached to the output shaft 37 of the speed reduction mechanism 38. By winding the wire 40, one end of which is attached to the lower portion of the water tank 15, the water tank 15 is inverted to the horizontal state about the horizontal shaft 30. This state is shown in FIG. In this state, the drying motor 27 is driven to drive the rotary tank 1
Rotate 8 at low speed. Further, the heater 44 is energized, the clutch 36 is released, the drive motor 35 is energized, and the blower fan 32 is rotated to enter the drying process. When the drying process is completed, the water tank 15 is returned to the vertical state again and a series of operations is completed.

In addition, as in the case where only drying is performed, the water tank 1
When there is a possibility that water remains in the water tank 5, the controller 50 performs the dehydration operation before the inversion operation of the water tank 15 when directly entering the drying process. By doing so, since dehydration is performed when the reversing operation is started, there is no water in the water tank 15, and in any case, high reliability is achieved without water leakage when the water tank is reversed.

[0015]

As described above, the present invention is applicable to washing, rinsing,
It has a control device that performs the dehydration process in a substantially vertical state of the water tank and the drying process in a substantially horizontal state of the water tank.Since the controller performs the dehydration operation before driving the reversing device, it is necessary to put it in the water tank before inversion Even if water remains, there is no water in the aquarium due to dehydration, and there is no water leakage during inversion.
It is possible to obtain high reliability.
