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

2 and 3 show a power conversion device for a two-chamber washing machine according to the present invention, the two-chamber washing machine power conversion device is a drive motor rotary shaft 2 and the drive motor rotary shaft built in one drive motor ( 2) the second gear (6) and the third pulley (14) having a second pulley (12) for turning the pulsator of the washing tank in half or the high speed rotation of the dewatering tank of the dehydration tank in conjunction with 2). It is comprised by the 3rd gear 8 which has.

The drive motor rotary shaft 2 is rotated forward / reverse at a high speed and a low speed by a drive motor, a first gear 4 is arranged at a stop portion, and a first pulley 10 is installed at an upper end portion thereof. A first clutch boss 16 having a clutch spring 26 is installed between the first gear 4 and the first pulley 10.

The second gear 6 is gear-coupled with the first gear 4, a second pulley 12 having the same height as the first pulley 10 is installed in the upper end of the shaft, the second gear ( A second clutch boss 18 having a clutch spring 26 is provided between 6) and the second pulley 12.

The third gear 8 is gear-coupled to the first gear 4 so as to face the second gear 6, and a third pulley 14 is installed at the lower end of the shaft, and the third gear 8 A third clutch boss 20 having a clutch spring 26 is provided between the third pulleys 14.

In addition, the first pulley 10 and the second pulley 12 are connected to the laundry pulley 46 of the laundry shaft 48 and the V-belt 34, and the third pulley 14 is the dehydration shaft 52 ) Is connected to the dehydration pulley 50 and the V-belt (32).

It also has two end parts which are periodically left / right operated by the synchronous motor 30 and come into contact with the first and second clutch bosses 16 and 18, respectively, and the second pulley 12 has the first end. A first clutch lever 38 is provided to interlock with the first pulley 10 or idle.

A second actuated by an adjustment knob 28 and having an end in contact with the third clutch boss 30 and causing the third pulley 14 to be rotated or idle by the drive motor rotary shaft 2; The clutch lever 24 is installed.

The operation of the apparatus of the present invention configured as described above is as follows.

The second pulley 12 is a pulley used in the washing stroke, and the third pulley 14 is a pulley used in the dehydration stroke.

The first pulley 10 receives power directly from the drive motor rotary shaft 2 of the drive motor via the clutch spring 26, and the second pulley 12 receives power through the second gear 6. At this time, the rotation directions of the first gear 4 and the second gear 6 are opposite to each other as indicated by the arrow.

In the first washing stroke, the selection switch 28 is operated to adjust the positions of the first and second clutch levers 22 and 24.

That is, the second clutch lever 24 of the dehydration shaft 52 pushes the third clutch boss 20 to release the engagement of the third pulley 14 and the third gear 8 to idle.

At this time, the selection knob 28 turns on the synchronous motor 30 to control the clutch bosses 16 and 18 provided on the upper side of the first gear 6 and the second gear 8. That is, the synchronous motor 30 rotates left / right periodically so that a pair of tips connected to the first clutch lever 22 interrupts the first clutch boss 16 and the second clutch boss 18. In this state, the first and second pulleys 10 and 12 are connected by the V-belt 34.

When washing and dehydration are performed at the same time, the washing portion operates as described above.

When the position of the selection knob 28 is changed, the third clutch boss 20 is released by the second clutch lever 24, so that power is transmitted by the clutch spring 26 through the dehydrating poly 50. .

When only the dehydration stroke is executed, if the selection knob 28 is placed in the neutral position, the first pulley 16, the second pulley 18, and the first clutch lever 38 are placed in the neutral position, thereby performing the washing stroke. All power sources are shut off.

Power interruption of the first clutch lever 38 in this state causes the power supply of the synchronous motor 30 to be short-circuited when the selector knob 28 is placed in the dewatering state, and the second spring 42 is connected to the first clutch lever 22. ) Toward the first pulley 10 to reach the neutral position is caught by the first spring 40 to reach the neutral position. In this way it will cut off the power of the laundry shaft.

In the accompanying drawings, reference numeral 36 denotes a fixed shaft, 38 denotes a flow shaft, 40 denotes a first spring, and 66 denotes a bearing.

According to the present invention as described above, by operating the pulsator in the washing tank and the dehydration tank in the dehydration tank with a single motor, there is an effect that can improve the productivity by reducing the production cost and the reduction of assembly parts and assembly labor. .
