To increase the efficiency, the dehydration tank should be fixed.

In order to satisfy the above requirements, the conventional automatic washing machine clutch prevents the dehydration tank from moving due to the water flow generated during washing by the mechanism of the one-way clutch bearing 25 and the brake band 23.

The present invention is to move away from the washing stroke of the commercially available fully automatic washing machine clutch in the washing stroke by rotating the washing plate and the dehydration tank in the opposite direction by the mechanism of the present invention to fix the existing dehydration tank and to reverse the washing plate left and right washing Rather than proceeding to improve the washing efficiency and to reduce the washing time was invented for the purpose of reducing power consumption.

Description

Full automatic washing machine clutch system

The present invention is a clutch device for a full automatic washing machine made in a dehydration tank at the same time washing and dehydration, the dehydration tank is rotated by power in the opposite direction to the rotation direction of the washing plate when the washing plate rotates during the washing stroke.

Therefore, the prior art of the present application is a commercially available clutch for a fully automatic washing machine as shown in Figure 1 receives the power of the motor to the pulley 28 and transmits its power to the pulley shaft (1a) to rotate the speed of the motor in the gear unit 35 After decelerating and transferring the power to the washing shaft 19, the washing plate (not shown) connected to the washing shaft 19 to the left and right proceeds the washing administration, in which the dehydration tank to increase the washing efficiency It should be fixed like a laundry plate.

In order to satisfy the above requirements, the conventional fully automatic washing machine clutch prevents the dehydration tank from moving by the flow of the dehydration tank during washing by the mechanism of the one-way clutch bearing 25 and the brake band 23.

In another prior art, as shown in FIG. 1, the dehydration tank is not fixed when the washing plate rotates by freeing the brake band 23 of the clutch device during washing and using a ball bearing instead of the one-way clutch bearing 25. There was a clutch device in which the dehydration tank rotates slightly slower than the rotation speed of the washing plate due to the water flow of the washing plate, causing the dehydration tank to rotate in the existing direction due to inertia when the washing plate is inverted.

The first clutch device is a conventional clutch device and the second clutch device appears to rotate in the reverse direction when the dehydrating tank rotates, but the dehydrating tank does not generate water flow by its own power, but when the washing plate rotates. Rotation is caused by the water flow generated by the washing plate, rather, it weakens the water flow generated by the washing plate, and there is an element that inhibits the washing power.

In view of the above points, an object of the present invention is to rotate the washing plate, which has a conventional automatic washing machine clutch, so that the dehydrating tank is fixed during the washing operation and the dehydrating tank is simply rotated by the water flow of the washing plate. To escape from the clutch system, which only seems to turn, the dehydrating tank rotates in the opposite direction to the rotation direction of the washing plate by using power to improve the washing power of the washing machine, thereby reducing the power consumption by increasing the washing power and reducing the washing time. It is to provide a clutch device of a fully automatic washing machine.
