First, a water tank 12 in which a predetermined amount of wash water is freshly installed inside the rectangular main body 11 is suspended by a hook rod 17.

Next, the cylindrical washing tub 13 is installed in a rotatable state inside the water tank 12, and the washing tub 13 is formed of a cylinder in which a side wall is completely blocked, and a shaft hole 13a is formed at the center of the bottom of the washing tub 13. The water tank 12 and the through hole 13b are formed in the periphery of the shaft hole (13a) is formed to flow the wash water supplied into the washing tank 13 to the water tank 12 to the washing tank 13 And the water level of the water tank 12, and these holes (13b) is to discharge the washing water generated from the wet clothes in the dehydration process toward the water tank (12).

In addition, a power switching means 16 that is rotated by a motor 15 is installed in the center of the bottom surface of the water tank 12, the power switching means 16 is composed of a washing shaft 16a and a dehydration shaft 16b at the top. The washing shaft 16a is coupled to the stirring blades 14 and the dehydration shaft 16b to the bottom surface of the washing tank 13, and the stirring blade 14 is rotated forward and backward during the washing process. 13) Stirs the wash water supplied to the inside to cause the rotation flow.

Here, the coupling structure of the washing tub 13 and the dehydration shaft 16b will be described in detail. As shown in FIG. 3, a circular fixing bracket 13c is formed at the bottom of the washing tub 13, and the fixing bracket 13c The fixing flange 13d is formed outward at the upper end and is coupled as the washing tub 13 and the screw 13e, and a shaft hole 13f through which the washing shaft 16a penetrates is formed at the center of the bottom surface of the fixing bracket 13c.

The main body 1 is provided with a watering device. First, a pumping fan 18a, such as an impeller, is formed on the washing shaft 16a inside the fixing bracket 13c, and is rotated forward and backward with the washing shaft 16a. When the pump pan 18a rotates forward and backward, the water in the water tank 12 rises between the washing tank 13 and the water tank 12.

Then, a ring-shaped shower guide 18b is coupled to the upper end of the water tank 12 as a screw 18c, and the inner side of the shower guide 18b is positioned inside the washing tank 13 to wash the washing tank 13 and the water tank. It is preferable to allow water pumped between (12) to be sprayed to the center of the stirring blade (14).

The above description is only one embodiment of the present invention and can be changed as many within the scope of the present invention.

Referring to the operation of the subject innovation configured as described above in detail.

The washing machine configured as described above puts a predetermined amount of laundry into the washing tank 13, and then inputs a detergent thereto, and proceeds with a water supply administration. At this time, the water supplied through the water supply port (not shown) above the main body 11 is The water is immediately dropped into the washing tank 13, and the water supplied to the washing tank 13 is stored in the water tank 12 through the hole 13b at the bottom of the washing tank 13.

When the amount of water specified in the water tank 12 is stored, the washing stroke proceeds continuously. When the motor 15 rotates forward and backward in the washing stroke, its rotational force is transmitted to the power switching means 16 and at the same time power switching. After decelerating in the means 16, the forward rotational power is transmitted to the stirring device 14 through the washing shaft 16a, whereby the washing water causes the rotating water flow as the stirring device 14 rotates forward and backward. The laundry proceeds as if the laundry is rubbed together.

In other words, when the disk-shaped stirring device 14 is rotated, the washing water is circulated by each of the blades protruding radially on the upper part of the stirring device 14, and in the process, the laundry is rubbed with each other by rotating water. The laundry is in progress.

In addition, when the stirring device 14 is rotated forward and backward in the washing process, the pump pan 18a coupled with the washing shaft 16a is rotated forward and backward, so that the water in the water tank 12 rises between the washing tank 13 and the water tank 12. The water thus raised is guided by the shower guide 18b and dropped into the washing tank 13 to dissolve the detergent mixed in the laundry.

That is, since much water rises by the pumping pan 18a, it falls to the washing tank 13 with strong force, and the dissolution rate of detergent is greatly improved.

After the washing stroke is completed, the washing water is first drained, and then a rinsing stroke is performed. During the rinsing cycle, the normal water stroke is performed, and then, the stirring blade 14 is reversely rotated to rinse the detergent solution remaining in the laundry. As the pump pan 18a coupled with the washing shaft 16a rotates forward and backward, the water in the water tank 12 rises between the washing tank 13 and the water tank 12, and the water thus raised is guided by the shower guide 18b. Received drop into the washing tank 13 is to rinse the laundry clean. In the rinsing cycle, the above process is repeated several times, so that the laundry detergent is completely removed.

After the rinsing cycle is repeatedly completed, the dehydration stroke proceeds. When the motor 15 rotates in one direction at a high speed in the dehydration process, the washing shaft 16a and the dehydration shaft 16b rotate together by the power switching means 16 at a high speed. At this time, the washing tub 13 is rotated at a high speed. When the washing tank 13 is rotated at a high speed, centrifugal force is applied to the laundry to spread the laundry toward the inner circumferential surface of the washing tank 13, and the washing water contained in the laundry is dehydrated. In addition, the dehydrated wash water is discharged toward the water tank 12 along the through hole 13b of the bottom surface of the washing tank 13, and the discharged wash water is drained to the outside through the drainage means.

Therefore, the present invention pumps the water in the water tank 12 to the upper end of the water tank 12 by using the pumping fan 18a on the washing shaft 16a between the washing tank 13 and the water tank 12, and then, at the top of the water tank 12. By sprinkling with the washing tank 13 using the installed shower guide 18b, as well as the structure of the watering device is extremely simplified, there is an effect that can maximize the dissolution rate of the detergent by spraying a lot of water at the same time.
