The present invention relates to a power transmission converter of a washing machine drive system in which a shaft of a washing machine motor and a shaft of a washing tub are arranged in a straight line. The key holder is spoken at one end of the operated key rod, and the dehydration shaft connecting key and the dehydration side connecting bar are connected to each other through the key holder and the bearing, and a lower connection side of the key rod is installed at the lower side thereof. It relates to a power transmission converter for driving the washing machine to selectively transfer the dehydration and washing power to the washing machine shaft by the up and down operation.

In general, a washing machine that performs washing and dewatering functions includes a clutch unit that is extended to a motor and a shaft that is extended to a belt, thereby changing the washing and dewatering modes by driving the belt.

In the conventional washing machine drive unit power transmission system related to this technology, as shown in FIG. 1, the washing machine outer cylinder 22 is installed outside the washing machine dehydration container 21, and the motor 23 provided at one side of the lower part thereof is The pulley 25, which is extended from the motor shaft 24, is rotated by being rotated by the belt 26 with the other pulley 25 ′, while the washing barrel 28 is interposed between the shaft and the washing machine clutch 27 by the shaft 26. It consists of a configuration that is connected with.

Therefore, when the pulley 25 extended with the motor shaft 24 is driven by the driving of the motor 23, the other pulley 25 'connected to the pulley 25 and the belt 26 rotates. The rotational force is converted into the washing or dewatering mode through the washing machine clutch unit 27 so that the rotational force is transmitted to the washing container 28 and the washing machine dehydrating container 21.

However, in the conventional washing machine power transmission system having the above structure, the driving force of the motor 23 is transmitted to the washing machine clutch unit 27 by the rotation of the belt 26, so that the driving efficiency is lowered, and the motor ( 23) and the center of gravity of the washing machine clutch portion 27 is out of the laundry container 28, so noise and vibration are severely generated when driving the washing machine due to an imbalance, and the production is difficult due to the structural complexity as described above, and easily breakdown occurs. There is a problem.

In addition, the belt 26 which transmits the driving force of the motor 23 to the washing machine clutch unit 27 is made of an elastic rubber material, which is easily broken when an overload occurs in the washing machine, thereby stopping the operation of the washing machine. Is there.

The present invention is to improve the conventional problems as described above, the object is, the key holder is spoken to one end of the key rod operating up and down by the circular arc of the washing and dehydration guide key, the key holder Dehydration cylinder shaft key is provided on the upper end of the hook connecting shaft of the laundry tub connecting shaft installed via the bearing, and the lower end of the laundry tub connecting shaft is provided with a dehydration shaft connecting key to move up and down integrally with the dehydration shaft, By being installed, by adjusting the up and down movement of the key holder by the washing and dehydration guide key, the drive mode applied from the motor can be selectively and reliably switched by dehydration and washing mode, as well as by the washing tub and dewatering in the washing tank. The barrel rotates at the same rotational speed and constitutes a key holder and connecting key connecting the shaft of the motor and the two shafts of the washing tub. Increasing the driving efficiency and to provide a power transmission converting apparatus of a washing machine with a drive noise during washing machine operation, and the vibration can be significantly reduced.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a view showing a power transmission converter of the washing machine drive unit according to the present invention, (a) is a configuration diagram of the power transmission system when the washing machine dewatering, (b) is a configuration diagram of the power transmission system during washing. , The key holder 3 is connected to one end of the key rod 2 which is operated up and down by an arc-shaped rotational movement of the washing and dehydration guide key 1, and the laundry container is installed inside through the bearing 4. The dehydration barrel shaft key 7 is communicated with the dehydration barrel shaft 8 above the hook end 6 of the connecting shaft 5, and the key is connected to the lower end of the laundry tub connecting shaft 5 via an inner dehydration shaft 9. A dehydration connection key 10 that is raised and lowered integrally with the holder 3 is installed, and a lower part of the laundry barrel 11 is connected to the lower part of the dehydration connection key 10 by the lower part of the dehydration connection key 10. It consists of a configuration that is installed washing shaft 12 for rotating.

Referring to the operation and effect of the present invention made of such a configuration as follows.

That is, as shown in Fig. 2 (a) and (b), when the key rod (2) is pushed upward by the arc of the washing and dehydration guide key (1) during the dehydration of the washing machine, integrally with this The hook connecting end 5 and the dehydrating shaft key of the washing tub connecting shaft 5 are raised while the washing tub connecting shaft 5 and the dehydrating tubular shaft key 7 installed therein are raised via the key holder 3 and the bearing 3. (7) comes into contact. At this time, the dehydration shaft shaft 8 connected to the dehydration shaft shaft key 7 is integrally rotated by the rotation of the dehydration shaft 9 of the motor to perform the dehydration function.

Subsequently, when performing the washing function of the washing machine, as shown in FIG. 2 (b), the key rod 2 is pushed downward by the arc rotation of the washing and dehydration guide key 1, and integrally with this. In the dehydration cylinder shaft (7) connected to the dehydration cylinder shaft (8), the laundry container connecting shaft (5) spoken with the key holder (3) is lowered, and the dehydration shaft connection key located at the lower end of the tub connection shaft (5) ( 10 is in contact with the washing shaft (12).

At this time, as the washing shaft 12 is rotated by the driving of the motor, the washing tub connecting shaft 5 rotates the washing tub shaft 11 in a state in which the dehydrating tubular shaft key 7 is separated as described above, thereby washing function. Can be done selectively.

According to the washing machine driving unit and the power transmission converting apparatus according to the present invention as described above, by controlling the up and down movement of the key holder by the laundry and dehydration guide key to selectively and reliably drive mode applied from the motor by mechanical operation. In addition to changing the dehydration and washing mode, the laundry and dehydration tanks rotate at the same speed in the washing tank, and a key holder and a connection key connecting the shaft of the motor and the two shafts of the washing tub are configured to increase driving efficiency and drive the washing machine. There is an excellent effect that the noise and vibration can be significantly reduced.
