Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a washing machine, and particularly to a washing machine that can efficiently wash clothes with a small output motor.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the washing machine of the present invention applied to a two-tub washing machine will be described below with reference to the drawings.

The washing machine of the present invention has a first washing tub 1, a second washing tub 2, and a dehydration tub 3, and the first washing tub 1 is attached to a first pulsator shaft 6 having a first boot'J5. A first pulsator 7 is installed, a second pulsator 10 attached to a second pulsator shaft 9 having a second pulley 8 is installed in the second washing tub 2, and a second pulsator 10 is installed in the dehydration tank 3 to be rotated by a dehydration motor 11. A first clutch 16 is installed between the first pulley 5, a third pulley 15 attached to the motor shaft 14 of the washing motor 13, and a first clutch 16 that transmits only clockwise rotation. A second belt 20 is mounted between the second pulley 8, a fourth pulley 18 attached to the motor shaft 14 of the washing motor 13, and a second clutch 19 that transmits only counterclockwise rotation. It is configured by mounting it on a rack.

The electric circuit diagram of the two-tub electric washing machine configured as described above will be explained with reference to FIG.・Rinse time switch 23
, a reversing switch 24, select switches 25 and 26, and a washing motor 13 are connected in series.

In this embodiment, the reversing switch 24 is set to automatic reversal for 10 seconds on the fixed terminal 24a side and 5 seconds on the fixed terminal 24b side, and the clockwise rotation of the washing motor 13 is set for 10 seconds and the counterclockwise rotation for 5 seconds. Set to automatic reversal of seconds.

Next, the operating conditions of the two-tub washing machine of the present invention constructed as described above will be explained. First, when washing is done in the first washing tub 1, the washing/rinsing time switch 23 is set at a predetermined time. At the same time, the select switch 25 is turned on (closed), the washing motor 13 is energized, and the first pulsator 7 is turned on.
is rotated to perform washing in the first washing tub 1.

At this time, the first pulsator 7 repeatedly rotates clockwise for 10 seconds and stops for 5 seconds due to the action of the reversing switch 24 and the first clutch 16.

Next, when washing in the second washing tub 2, the washing/rinsing time switch 23 is set to a predetermined time, the select switch 26 is turned on, the washing motor 13 is energized, and the second pulsator 10 is rotated. Washing is done in the second washing tub 2.

At this time, the first pulsator 10 repeatedly rotates counterclockwise for 5 seconds and stops for 10 seconds due to the action of the reversing switch 24 and the second clutch 19.

When washing in the first washing tub 1 and the second washing tub 2, the washing/rinsing time switch 23 is set to a predetermined time, the select switches 25 and 26 are turned on, the washing motor 13 is energized, and the washing motor 13 is energized. 1 pulsator γ and 2nd
The pulsator 10 is rotated to perform washing in the first washing tub 1 and the second washing tub 2.

At this time, the action of the reversing switch 24 and the first clutch 16 causes a repeating operation of rotating clockwise for 10 seconds and stopping for 5 seconds. It becomes a repetitive action.

In the case of any of the above washing operations or separately, the dehydration tank 3
When dewatering is performed in
2 is rotated to perform dehydration in the dehydration tank 3.

In addition, in the above explanation, the washing tub is divided into the first washing tub 1 and the second washing tub.
Although we have explained the case where the washing tub 2 is separated by a partition plate, the partition plate that partitions the first washing tub 1 and the second washing tub 2 is removable, and when washing large laundry, the partition plate can be removed. In this case, the washing/rinsing time switch 23 is set to a predetermined time, the select switches 25 and 26 are turned on, and the washing motor 13 is turned on.
When energized and washed, the first pulsator 7 and the second pulsator 10 rotate alternately, so that the laundry is less likely to be twisted, compared to a case where two pulsators rotate at the same time.

Furthermore, by making the rotation times of the first pulsator 1 and the second pulsator 10 different, for example by making the rotation time of the first pulsator γ longer than the rotation time of the second pulsator 10, the first washing tub 1 can be changed to a normal washing water flow. The second washing tub 2 can be used for washing light items, rinsing water, and rinsing water.

Since the washing machine of the present invention has the above-described configuration, the output of the motor that rotates two pulsators only needs to be the output that rotates one pulsator, and washing can be carried out efficiently with a small output motor. By using a switch, the two pulsators can be rotated alternately or only one of them can be rotated as desired, allowing the user to select an effective method of use.
