The present invention relates to an agitating device for a washing machine, and more particularly, to an agitating device for a washing machine which is provided with a plurality of auxiliary washing rods around the washing rods for raising and lowering the washing rods on the rotating circular plate, .

Generally, as shown in FIG. 1, a washing machine is provided with a washing tub 3 in which a water tub 2, in which wash water is drained, is suspended and a laundry is contained in a water tub 2, do. A stirring vane 4 for generating a water current is provided in the washing tub 3 and a power switching member 5 for rotating the stirring vane 4 in the forward and reverse directions and rotating the washing tub 3 at the time of dewatering is provided in the water tub 2, Lt; / RTI > Further, the power switching member 5 is connected to the motor 6 via the belt 6a. When the laundry is placed in the washing tub 3 and the washing water is supplied, the power switching member 5 is rotated by driving the motor 6. At this time, the power switching member 5 is selectively rotated while the stirring vane 4 is connected to the stirring shaft 5a and the washing tub 3 is connected to the washing tub axis 5b. That is, when the agitating shaft 5a is rotated in the normal or reverse direction during washing, water is generated by the agitating blades 4 and washing progresses. When the washing tub 5b is rotated at a high speed during dewatering, The laundry is dehydrated. However, since the agitating blades 4 are formed in the form of a disk and a plurality of projections are formed in the upper part to generate a water flow, the washing performance is lowered. Since the water stream is formed by the protrusions, the water stream is simply generated, which lowers the stirring efficiency of the laundry and the washing water.

SUMMARY OF THE INVENTION The present invention has been developed in consideration of the conventional problems, and it is an object of the present invention to provide an apparatus and a method for rotating a rotary disk, in which a rotary bar is mounted on an upper portion of a rotary disk, and a plurality of auxiliary rotary rods are installed around the rotary disk, So that the stirring efficiency of the washing machine can be improved. In order to achieve the above object, according to the present invention, there is provided a washing machine comprising: a washing tub provided in a water tank; and a power switching member provided on the bottom of the water tub for rotating the stirring shaft in normal and reverse directions, ; A plurality of planetary gears meshed between the sun gear and the internal gear of the inner surface of the rotary disk; A washing bar 30 coupled to the serration axis of the sun gear; And an auxiliary washing rod formed on the respective planetary gears and rotated. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 2 is a perspective view of the stirring device of the present invention, FIG. 3 is a sectional view of the stirring device of the present invention, and the same components as those of the first embodiment are denoted by the same reference numerals. A sun gear 20 coupled to an agitating shaft 5a of a power switching member 5 is provided at the center of the interior of a rotary disk 10 provided at a lower portion of the washing tub 3 and having a plurality of projections 12 generating water flow. The sun gear 20 is provided with a washing bar 30 having a serration axis 21 formed at an upper center thereof and coupled with the serration axis 21 to generate a water flow at an upper portion of the rotating disk 10. In addition, a serration 31 coupled with the serration shaft 21 is formed in the inside of the washing bar 30 to transmit rotational force. A plurality of screws 32 are formed on the outer circumferential surface of the washing bar 30 so that the forward rotation of the washing bar 30 causes the upward rotation of the washing bar 30, Down pressure is generated. When the rising and falling pressures are respectively generated, the washing bar 30 is lifted and lowered by the serration axis 21 and the serration 31 to wash laundry. An internal gear 11 is formed on the inner peripheral surface of the rotary disk 10 and a plurality of planetary gears 40 are provided between the sun gear 20 and the internal gear 11 to rotate the respective planetary gears 40 Is rotated and revolved while the internal gear 11 is rotated. An auxiliary washing rod 41, which rotates in combination with each of the planetary gears 40, is installed on the rotary disk 10. This structured

In the present invention, the sun gear 20 is provided on the stirring shaft 5a of the power switching member 5 and is rotated together when the stirring shaft 5a is rotated during washing. At this time, the plurality of planetary gears 40 engaged with the sun gear 20 are rotated together to rotate the auxiliary washing rods 41. Further, when the serration shaft 21 is rotated by the rotation of the sun gear 20, the washing rods 30 engaged with the serration shaft 21 rotate together to generate a water flow. Therefore, a water stream is generated in combination due to the rotation of the washing rod 30 and the auxiliary washing rod 41. When the planetary gear 40 rotates, the rotary disk 10 engaged with the internal gear 11 is rotated. Since the positions of the auxiliary washing rods 41 are changed while the auxiliary washing rods 41 revolve by the rotation of the rotary disk 10, the position of rubbing with the laundry is changed and the washing performance is improved. Further, since the agitating shaft 5a is rotated in the forward and reverse directions, the washing rod 30 is lifted and lowered through the sun gear 20 coupled thereto. That is, when the washing bar 30 engaged with the serration shaft 21 formed on the upper part of the sun gear 20 rotates, the screw 32 formed on the outer circumferential surface of the washing bar 30 rubs against the water and an upward and downward pressure is generated, The washing bar 30 is lifted and lowered. Therefore, the washing property is improved due to the collision with the laundry. As described above, according to the present invention, the sun gear, the planetary gear and the internal gear are formed inside the rotary disk. At this time, the washing rod combined with the sun gear stirs the washing water, and the rising and falling pressure is generated, so that the washing rod is lifted and collided with the laundry. In addition, the water is generated by the auxiliary washing rods combined with the planetary gears, and the auxiliary washing rods revolve by the rotation of the rotating disk, so that water streams are generated in a complex manner, thereby improving the washing performance.
