The present invention relates to a water supply device for supplying cold water and hot water, and to a water supply device for a fully automatic washing machine that performs various water supply functions while simplifying a structure.

As shown in FIG. 1, the conventional fully automatic washing machine is fixedly supported on the upper side of the washing machine main body 1 via the supporter 3, and is fixed by the suspension bar 5. It is mounted at the height to prevent vibration during washing and dehydration, and is provided with an outer tub 7 which stores washing water, and a motor 9 driven by power is disposed at an outer bottom surface of the outer tub 7. And a power transmission device 13 mounted on the outside of the bottom surface of the outer tub 7 so as to receive a driving force from the motor 9 via the belt 11 to drive a pulsator or a washing and dehydration tank to be described later. ) And a washing and dewatering tank 15 rotatably mounted in the outer tub 7 so as to dehydrate the laundry by centrifugal force due to the rotation of the power transmission device 13.

The washing and dehydration is performed so that washing is performed by receiving a power of the motor 9 through the power transmission device 13 and forming a water flow in the washing water contained in the washing and dehydrating tank 15 while being rotated forward and reverse. A pulsator 17 rotatably mounted on the bottom surface of the tank 15 is disposed, and the water level of the wash water stored in the outer tank 7 is stored above the main body 1 by a level sensor not shown. The water supply pipe 19 which detects and supplies wash water according to the laundry in the outer tub 7 is disposed, and the upper part of the washing and dehydrating tank 15 is rotated so that the laundry rotates even when the laundry is biased to one side during dehydration. The balancer 21 is arranged to keep the dehydration tank 15 horizontal, and a drain pipe 23 for discharging the contaminated washing water generated during washing and rinsing is disposed at one lower side of the outer tank 7.

The fully automatic washing machine configured as described above puts laundry and detergent into the washing and dehydrating tank 15, selects washing conditions by an operation unit (not shown), and operates the washing machine to supply the washing water into the outer tank 7 through the water supply pipe 19. do.

When the washing water supplied in the outer tub 7 reaches the amount necessary for washing the laundry put into the washing and dewatering tank 15, the motor 9 starts to rotate, and the rotational force of the motor 9 is the belt 11. It is transmitted to the power transmission device 13 through.

The power transmission device 13 receives the rotational force of the motor 9 to decelerate, rotates the pulsator 17 rotatably disposed on the shaft, stores it in the washing-and-dehydrating tank 15 to form a water flow, and washes. .

When the washing is finished in this way, the solenoid valve (not shown) disposed below the outer tank 7 is turned on (opened), and the contaminated washing water stored in the outer tank 7 and the washing and dehydrating tank 15 is drained. It is discharged to the outside through (23).

Then, when the drainage of the wash water is completed, the solenoid valve (not shown) is turned off, and the rinsing wash water is supplied into the outer tub 7 through the water supply pipe 19. Next, when the water level required for rinsing the laundry is reached, the pulsator 17 repeats the forward and reverse rotations according to the driving force of the power transmission device 13 which has received the driving force of the motor 9 as described in the washing stroke described above. Rinse off any contaminants and detergents from your laundry.

When the final rinsing stroke is completed by repeating such a rinsing cycle a plurality of times, the rinse stored in the outer tank 7 and the washing and dehydrating tank 15 through the drain pipe 23 is turned on (opened). The completed wash water is discharged to the outside.

At this time, the washing and dewatering tank 15 is rotated in one direction according to the driving force of the power transmission device 13 to dehydrate the washing water and the washing water permeated to the laundry in the washing and dewatering tank 15.

However, the conventional washing machine configured as described above uses a wash water made of hard water containing a large amount of minerals such as calcium and magnesium, so that the solubility of the detergent is not reduced when washing, and when the rinsing is not completed, There was a problem that the stain remains.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the object of the present invention is to increase the cleaning capacity by softening the hard water with a simple structure, and at the same time the structure of the water supply device to facilitate the soft water production Simplicity and at the same time to provide a water supply device for a fully automatic washing machine that performs a variety of water supply functions.
