BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fully automatic washing machine having a washing tub in which a dehydrating tub is installed.

[0002]

2. Description of the Related Art In a conventional fully automatic washing machine of this type, water in a washing tub is discharged from an outlet provided at the bottom of the washing tub.
A weight is used as a means for preventing vibration during dehydration.

[0003]

In the case of the conventional fully automatic washing machine, it is conceivable to enlarge the discharge port at the bottom of the washing tub in order to shorten the draining time of the water in the washing tub. Due to the size of the mouth, etc., the discharge port cannot be enlarged, the discharge amount is limited, there is a limit, and it takes a lot of time to shift to the next step such as dehydration. Further, when a weight is used, there is a limit in terms of carrying the machine and strength of the floor at the installation site. Further, there is a problem that vibration of the washing machine main body and noise due to the motor etc. become a problem.

In consideration of the above points, the present invention is a fully automatic system capable of shortening the time for draining water from the washing tub, shifting to the next step such as dehydration in a short time, and realizing vibration and sound insulation. The purpose is to provide a washing machine.

[0005]

In order to solve the above-mentioned problems, a fully automatic washing machine of the present invention is provided with a washing tub having a dehydrating tub therein, an outlet formed in the washing tub, and an inlet. A tank, an outflow pipe having one end connected to the outflow port and the other end connected to the inflow port, and a discharge port formed in the tank, so that the outflow amount of the outflow port is larger than that of the discharge port. It was done. Further, it is desirable that the bottom of the tank covers the bottom of the washing machine body. Further, it is preferable to provide a pump for supplying the water in the tank to the washing tub.

[0006]

In the fully automatic washing machine of the present invention constructed as described above, the outflow port of the washing tub and the inflow port of the tank are connected by the outflow pipe, and the outflow amount of the outflow port is the discharge amount of the outflow port of the tank. Since it is made larger, the drainage time of the water in the washing tub, which was limited by the size of the drainage outlet at home, is greatly shortened, and the next process such as dehydration can be transferred in a short time. Further, since the bottom of the tank covers the bottom surface of the washing machine main body, the water stored in the tank from the washing tub becomes a weight, the vibration of the main body is prevented, and the noise caused by the motor is prevented.
Furthermore, by providing a pump for supplying the water in the tank to the washing tub, at the end of the final dehydration process, the water in the tank is supplied to the washing tub and reused as the washing water for the next washing, A water saving effect is obtained.

Is a communication hole formed at the bottom of the dehydration tub 3 and communicating with the washing tub 2.

Reference numeral 8 denotes a motor provided below the washing tub 2, which is connected to the dehydration tub 3 and the stirring blade 6 via a power transmission mechanism (not shown). Reverse rotation is performed, and during dehydration, the dehydration tank 3 and the stirring blade 6 are both rotated in one direction at high speed. 9 is a 2 formed on the bottom of the washing tub 2.
The individual outlets 10 are outflow valves provided at both outlets 9.

Reference numeral 11 denotes a tank provided at the bottom of the main body 1, and the bottom of the tank 11 covers the bottom surface of the main body 1. Reference numeral 12 is a recess formed in the center of the tank 11, and the motor 8 is located in the recess 12. Reference numeral 13 denotes two inlets formed in the peripheral portion of the recess 12 of the tank 11.

Outlet pipes 14 each have one end connected to the outflow port 9 and the other end connected to the inflow port 13, 15 is a discharge port formed at the rear of the tank 11, and 16 is provided at the discharge port 15. It is a discharge valve, and through the discharge valve 16, the discharge port 15
The amount of water discharged from is equal to the amount of water discharged from one outlet 9. That is, the ratio of the discharge amount of the discharge port 15 and the discharge amount of the two outlets 9 is 1: 2.

Reference numeral 17 is a pump provided in the tank 11,
Reference numeral 8 denotes a water supply pipe having one end connected to a pump 17, which is erected along the outer surface of the washing tub 2, and a water supply port 19 at the other end is located at an upper surface opening of the dehydration tub 3, and the pump 17 allows the inside of the tank 11 to be located. Water is supplied to the washing tub 2 through the water supply port 19.

After the washing process is completed, two outlets 9 are provided.
The outflow valve 10 is opened, and the washing water in the washing tub 2 flows out into the tank 11 through the outflow pipe 14 and the inflow port 13 and is stored in the tank 11. The outflow time of the wash water at this time is a half of the time when it is directly discharged from the discharge port 15 of the tank 11. And during the dehydration process,
The washing water stored in the tank 11 serves as a weight that prevents vibration of the main body 1 during dehydration.

Next, during the rinsing process, the drain valve 16 of the tank 11 is opened, the washing water in the tank 11 is discharged during the rinsing process, and the next pre-rinsing tank 2 is prepared for the outflow of water.
During the final rinsing and dehydration process, the discharge valve 16 of the tank 11 is not opened, and during the next washing process, the water stored in the tank 11 is supplied to the water supply pipe 18 by the water supply pump 17.
Water is supplied to the washing tub 2 through the water supply port 19 and reused as washing water. The user can select whether to reuse the water in the tank 11.

When the fully automatic washing machine of the above embodiment is constructed at low cost, one large outlet 9, outlet valve 10 and outlet pipe 14 are used, and the discharge amount of the outlet 15 of the tank 11 is increased. And the outflow amount of the outflow port 9 is set to 1: 2. Further, when it is not necessary to reuse the water in the tank 11, the water supply pump 17, the water supply pipe 18, and the discharge valve 16 of the tank 11 are not necessary, and the tank 11 is downsized and configured at low cost.

In this case, since the drain valve 16 of the tank 11 is not provided, when the water in the washing tub 2 is completely drained, the tank 11
Half of the water used for washing or rinsing is stored in the inside, and then the water in the tank 11 decreases with time, but in the dehydration process, the largest vibration is at the start of dehydration. At this point, the water in the tank 11 has been sufficiently stored and functions as a weight. In the above embodiment, the ratio of the discharge amount of the discharge port 15 to the discharge amount of the discharge port 9 is set to 1: 2, but the ratio is not limited to this, and the discharge amount of the discharge port 15 to the discharge amount of the discharge port 15 is not limited to this. The ratio may be increased, and if it is increased, the drainage time of the water in the washing tub 2 can be shortened accordingly.
