The present invention relates to a power transmission device of a fully automatic washing machine, and particularly to the power transmission device of the automatic washing machine to prevent the rotation of the dehydration tank during washing by the simple structure and convenience, and to facilitate the power conversion of the washing and dehydrating paper respectively. It is about.

In general, as shown in FIG. 1, a washing machine 2 is mounted in the washing machine body 1, and a driving means 3 is mounted at one side of the outer bottom of the washing machine 2, In the center of the outer bottom surface of the washing tank 2, the power transmission means 5 is connected to receive the power of the drive means 3 via the belt (4).

In addition, a rotatable dehydration tank (6) is mounted in the washing tank (2) so that the tip of the power transmission means (5) can rotate while receiving power and rotated, and at the bottom of the dehydration tank (6). The pulsator 7 which washes by forming a water flow in the wash water in the dehydration tank 6 while being reversed by receiving the power of the power transmission means 5 is mounted.

In the figure, reference numeral 3a is a pulley, 8 is a water supply means, and 9 is a drain means.

When the automatic washing machine configured as described above is supplied with a certain amount of laundry and detergent in the dehydration tank 6 and power is applied, and washing conditions are selected, hot water or cold water is selectively supplied through the water supply means 8. After a few seconds, the pulsator 7 mounted in the dehydration tank 6 is reversed several times through the power transmission means 5 in accordance with the operation of the driving means 3 to invert water several times to form a water flow. Will be done.

Then, when the washing is completed according to the washing course process, the washing water (eg, contaminated water) is drained to the outside in the washing machine body 1 according to the operation of the drainage means 9, and the programmed washing, rinsing, After the new washing water is supplied through the water supply means 8 by the process leading to the dehydration course and the rinsing process is performed several times, the dehydration tank 6 supplies the power of the driving means 3 to the power transmission means 5. Received through the medium is rotated at high speed to repeat the dehydration course process to complete the washing process through all the course process of the washing machine for a certain time.

As shown in FIG. 2, the power transmission device of the fully automatic washing machine, which is configured as in the related art, receives a driving force of the driving means 3 and is fixedly coupled to the pulley 10 that is interlocked through the belt 4. 11) is freely mounted, the drive shaft coupling 12 is forcibly fitted to the lower end of the drive shaft 11 and the lower connector 13 rotates through the two bushings 14 at the upper end thereof. The upper connector 15 is mounted on the upper side of the lower connector 13 so as to be integrally rotated freely.

In addition, a driven shaft coupling 16 having a dehydration tank 6 mounted on the upper end of the upper connector 15 is coupled in a serration manner, and two bushings are provided inside the driven shaft coupling 16. The driven shaft 18 which combined the pulsator 7 at the upper end via (17) is rotatably mounted.

On the other hand, the sun gear 20 is engaged with the front end of the drive shaft 11, and a plurality of planetary gears 21 are engaged with the outer side of the sun gear 20. In this case, the planetary gear 21 is formed by the shaft 24 between the upper carrier 22 coupled to the lower end of the driven shaft 18 in a serration manner and the lower carrier 23 mounted to the lower side thereof. It is installed to decelerate freely in rotation.

In addition, the planetary gear 21 rotates while its outer side meshes with the internal gear 25 formed inside the upper connector 15.

On the other hand, a ball bearing 27 is mounted on the outer circumference of the lower connector 13 to be coaxially integrated through the lower case 26 so as to easily rotate the lower connector 13. By the support member 29 of the plastic injection-molded bushing 28 press-fitted on the inner side of the lower connector 13 with respect to the upper part of the ball bearing 27 so that the lower connector 13 is rotated in one direction. Clutch bearing 30 is mounted, the support member 29 is mounted by the fixing means 31 by the combination of the bolt and nut (not shown) to be fixed to the lower case 26 through the edge thereof. It is.

On the other hand, the clutch spring 33 is mounted on the periphery of the lower connector 13 and the drive shaft coupling 12 to control washing and dehydration. At this time, the clutch spring 33 located on the lower connector 13 side is always bitten by the lower connector 13, and the clutch half 33 of the other half is inserted into the entire outer circumference of the clutch spring 33 (clamp holder). 34) is fixed.

In addition, a sleeve member 36 having a sawtooth shape is mounted on the outer circumference of the clutch holder 34 via the brake ring 35.

Meanwhile, a brake lever 37 is mounted on one side of the lower case 26, and the brake lever 37 is held inside the brake lever 37 when the brake lever 37 is operated.
