In general, a washing machine is a washing process that is set in advance, for example, a water supply stroke for supplying washing water to a washing tank, a washing stroke for washing laundry through the wash water supplied through the water supply stroke, and a rinsing rinsing for the laundry washed through the washing stroke. And a dehydration stroke for dewatering the laundry washed cleanly through the rinsing stroke.

In the conventional washing machine configuration having a series of washing process described above, as shown in FIG. 1, a storage tank 2 in which a predetermined amount of washing water is freshly installed is installed inside the rectangular body 1, and the storage tank 2 is washed. It is configured in a cylindrical shape so as not to interfere with the rotational flow generated in the process, which is suspended from the inside of the main body 1 by the hook rod 7.

The washing tank 3 is formed with a myriad of through holes 3a penetrating the inner and outer circumferential surfaces thereof, and these through holes 3a are Washing water supplied into the washing tank (3) flows into the water storage tank (2), whereby the water level of the washing tank (3) and the water storage tank (2) is matched, and these through holes (3a) to the wet laundry in the dehydration process Contaminated washing water and debris generated from the discharge to the reservoir (2).

On the other hand, a balancing ring or balancer (not shown) is installed on the upper inner circumferential surface of the washing tank 3 to mitigate the vibration of the washing tank 3 when dewatering.

Then, the rotating body 4 of the stirring device having a plurality of wings on the inner bottom of the washing tank 3 is installed so that the forward and reverse rotation, the rotating body 4 is the forward and reverse rotation in the washing process, the washing tank 3 ) Wash the water supplied to the inside, and the laundry is washed as if the laundry is rubbed by each other.

In addition, a power switching means 6 is installed in the center of the bottom surface of the water storage tank 2, the power switching means 6 is a washing shaft (6a) and dewatering shaft (6b) is formed on the upper, respectively, the washing The shaft 6a is coupled to the rotating body 4 inside the washing tub 3, the dehydration shaft 6b is coupled to the bottom of the washing tub 3, and the power switching means 6 is Forward and reverse rotation by the motor (5) combined with the bottom surface.

In other words, when the disk-shaped rotating body 4 is rotated, the washing water is circulated by each of the blades protruding radially on the upper part of the rotating body 4, and in the process, the laundry is rubbed with each other by rotating water. Lose.

In addition, when the rotating body 4 is rotated forward and reverse during the washing process, the storage tank 2 is vibrated by the rotation of the washing tank 3 and water, the storage tank 2 is the main body (1) through the hook rod (7) Vibration is alleviated by resilient hanging inside.

However, in the conventional washing machine, washing is deteriorated because the laundry is twisted with each other while the laundry is moved to the center as shown in the arrow of FIG. 1 by using the rotational water generated when the rotating body 4 is rotated forward and backward. However, this leads to extremely low washing efficiency. In other words, when rotating water flows, the laundry is rotated by rotating water and rubs with each other in this process, and washing proceeds. At this time, the laundry is twisted and twisted at the same time as the laundry is moved to the center. Since it is not rubbed well by the water flow, there is a problem that the washability is greatly reduced and the washing time is long accordingly.

The present invention was created in view of the above problems, by forming a jet port in which water is ejected by the rotational force in the rotating body to generate turbulence in the rotating water flow generated by the rotating body, It is an object of the present invention to provide a stirring device of a washing machine, which prevents entanglement by being rotated to the center of a rotating body and at the same time impinges a stream of water on a flowing laundry, thereby greatly improving washability.
