Referring to this, the washing method of the washing machine according to the present invention will be described as follows. .

First, the user puts a laundry cloth and detergent into the washing tank (laundry tank 12 / washing tank 13) and when the washing stroke of the washing machine is started through the user's key input, the washing water is supplied to the predetermined level. Supply through the valve (17).

Subsequently, when the washing water is supplied to the washing tank, the washing tank and the pulsator 15 perform left and right stirring by the first mode, the second mode, the third mode, the fourth mode, and the fifth mode, and perform the pulsing. Washing water rises to the pumping channel 14 by rotation of a pumping vane (not shown) configured at the lower end of the eater 15.

Washing water raised to the pumping channel 14 passes through the lint filter 16 and collects lint generated from the laundry cloth, and circulates the washing water through the pumping channel 14 to dissolve the detergent.

In addition, washing is performed by mechanical friction between the pulsator 15 and the laundry cloth due to the stirring operation of the pulsator 15.

At this time, the washing operation in the present invention is performed by the first mode, the second mode, the third mode, the fourth mode and the fifth mode and the first, second, third, fourth and fifth modes. The control sequence of the washing administration by the first control in the second mode and then the third mode. Subsequently, the control is performed during the washing time set by the user by controlling by the first mode, the fourth mode, and the fifth mode combined at the predetermined ratios, and again by the third mode.

In this case, the combination of the first mode, the fourth mode, and the fifth mode may be controlled by combining the first mode, the fourth mode, and the fifth mode at a predetermined ratio, and the first mode, the fourth mode, and the fifth mode. Can be controlled alternately.

The first mode, the second mode, the third mode, the fourth mode, and the fifth mode will be described in more detail as follows.

First, in the first mode, the pulsator 15 is rotated for a first set time T1 at a first set speed V1 or V1 'to perform left and right stirring.

Here, since the first mode is the same as the control by the conventional first mode described above, the detailed description thereof will be omitted.

Next, in the second mode, the pulsator 15 is washed with the water supply through the water supply valve 17 at the second set speed (V2 or V2 '). At the same time as)), it rotates for the second set time T2 and performs left and right stirring.

In detail, as shown in FIG. 3, the left and right stirring control by the second mode simultaneously watches the pulsator 15 and the washing tank during the second set time T2 at the second set speed V2. After rotating in the direction, the rotation of the pulsator 15 and the washing tank is stopped for a predetermined time.

Subsequently, the pulsator 15 and the washing tank are rotated counterclockwise at the same time for the set time T2 at the set speed V2 ', and then the rotation of the pulsator 15 and the washing tank is stopped for a predetermined time. do.

At this time, in the second mode, the second set speed V2 or V2 'is a predetermined speed smaller than the first set speed V1 or V1' and is low enough that no centrifugal force is applied to the laundry cloth. The second set time T2 is the same as the first set time T1.

Therefore, the washing stroke in the second mode has a rotation cycle as shown in FIG. 4 and the washing stroke in the second mode rotates at a low speed in the same rotational direction and rotational speed as the laundry cloth integrally with the water supply valve ( 17) is driven to perform water supply to uniformly infiltrate the wash water into the wash cloth. In addition, there is no washing water circulated through the pumping channel 14 during the washing operation in the second mode.

Next, in the third mode, the pulsator 15 is rotated for a third set time T3 at a third set speed V3 or V3 'to perform left and right stirring.

In detail, as shown in FIG. 5, the left and right stirring control by the third mode rotates the pulsator 15 in a clockwise direction for a preset time T3 at a preset speed V3. The rotation of the pulsator 15 is stopped for a preset time.

Subsequently, the pulsator 15 is rotated counterclockwise for the set time T3 at the set speed V3 'and the rotation of the pulsator 15 is stopped for a preset time.

6 to 7, the pulsator 15 may be operated at the third set speed V3 or V3 ′, which is a predetermined speed larger than the first set speed V1 or V1 ′. Is controlled during the third set time T3 equal to the first set time T1 or at the third set speed V3 or V3 'equal to the first set speed V1 or V1'. The first at the third set speed V3 or V3 'that is controlled for the third set time T3 longer than the set time T1 or a predetermined speed greater than the first set speed V1 or V1'. The third set time T3 may be controlled for a predetermined time longer than the set time T1.

In other words, in the present invention, the setting speed and setting time of the third mode can be controlled by the following setting conditions 1), 2) or 3).

1) V3> V1, T3 = T1 (shown in FIG. 6)

2) V3 = V1, T3> T1 (shown in FIG. 7)

3) V3> V1, T3> T1

(V1: first set speed, V3: third set speed, T1: first set time T3: third set time)

Therefore, when the washing operation according to the third mode, the third set speed (V3) is greater than the first set speed (V1) a predetermined speed or the third set time (T3) is greater than the first set time (T1) By increasing the predetermined time, the centrifugal force is added to the laundry cloth and the wash water as compared to the first mode, so that the surface of the wash water is parabolic as shown. That is, during the washing stroke in the third mode, the washing water circulated through the pumping channel 14 increases due to the greater centrifugal force than the first mode.

Next, in the fourth mode, the pulsator 15 and the washing tank are rotated for a fourth set time T4 at a fourth set speed V4 or V4 'to perform left and right stirring.

In detail, as shown in FIG. 8, the left and right stirring control by the fourth mode simultaneously watches the pulsator 15 and the washing tank for the fourth set time T4 at the fourth set speed V4. After rotating in the direction, the rotation of the pulsator 15 and the washing tank is stopped for a predetermined time.

Subsequently, the pulsator 15 and the washing tub are simultaneously rotated counterclockwise at the same time during the set time T4 at the set speed V4 'and the rotation of the pulsator 15 is stopped for a preset time.

At this time, in the fourth mode, the fourth set speed V4 or V4 'is smaller than the first set speed V1 or V1' and greater than the second set time V2 or V2 '. The fourth set time T4 is the same as the first set time T1.

That is, it has a rotation cycle as shown in FIG. 9 and the washing cloth is peeled off from the pulsator 15 and the washing tank during the washing operation in the fourth mode. At this time, the washing water circulated through the pumping channel 14 is very small compared to the first mode or the third mode.

Therefore, when the washing operation is performed by the fourth mode, the pulsator 15 and the washing tank are simultaneously left and right stirred, and the fourth set speed V4 is smaller than the first set speed V1 and the second set speed. By making it larger than V2, the friction force is uniformly transmitted to the cleaning cloth which is hard to transmit the mechanical friction force of the pulsator 15, and washing is performed.

Finally, in the fifth mode, the pulsator 15 and the washing tank are rotated for a fifth set time T5 at a fifth set speed V5 or V5 'to perform left and right stirring.

In detail, as shown in FIG. 10, the left and right stirring control by the fifth mode simultaneously watches the pulsator 15 and the washing tank for the fifth set time T5 at the fifth set speed V5. After rotating in the direction, the rotation of the pulsator 15 and the washing tank is stopped for a predetermined time.

Subsequently, the pulsator 15 and the washing tub are simultaneously rotated counterclockwise at the same time during the set time T5 at the set speed V5 ', and the rotation of the pulsator 15 is stopped for a preset time.

At this time, in the fifth mode, the fifth set speed V5 or V5 'is equal to the fourth set speed V4 or V4', and the fifth set time T5 is the fourth set time T4. It is longer than a predetermined time.

That is, at the same time as the pulsator 15, the washing tank, the washing cloth, and the washing water having the same rotation cycle as shown in FIG. 11 and the washing stroke according to the fifth mode, at the same fifth set speed V5 or V5 '. Rotate At this time, since the surface of the wash water is subjected to centrifugal force to the wash water to form a parabolic shape and the pulsator 15 and the washing tank rotate integrally, there is no wash water circulating through the pumping channel 14.

Therefore, the pulsator 15, the washing tank, the washing cloth, and the washing water are simultaneously stirred left and right by lengthening the fifth set time T5 longer than the fourth set time T4 during the washing operation in the fifth mode. Mechanical friction is not transmitted to the laundry cloth.

Washing is performed by uniformly transferring the frictional force to the washing cloth which is difficult to transmit the mechanical frictional force of the pulsator 15.

As described above, the first set speeds V1 and V1 'have the same magnitude, and the second set speeds V2 and V2' have the same magnitude. Further, the third set speeds V3 and V3 'are the same size, the fourth set speeds V4 and V4' are the same size, and the fifth set speeds V5 and V5 'are the same size.

Accordingly, in the present invention, the washing stroke is performed by combining the first, second, third, fourth, and fifth modes having different setting speeds or setting times, and thus, having a setting time smaller than the first mode. Circulates through the pumping channel 14 due to the control by the second mode to quickly and uniformly infiltrate the wash water into the laundry cloth and to the control by the third mode having a set speed or set time greater than the first mode. Increasing the washing water, which speeds up detergent dissolution and improves lint collection.

The fifth mode has a uniform washing time due to the control by the fourth mode smaller than the first mode and has a larger setting speed than the second mode, and has a set time longer than that of the fourth mode. Due to the control by the mechanical friction force of the pulsator 15 is not applied to the laundry cloth, there is no fear of damage to the laundry cloth.

In the washing method of the washing machine according to the present invention described above, washing is performed by combining a first mode, a second mode, a third mode, a fourth mode, and a fifth mode controlled by different washing speeds or washing times during a washing stroke. The washing performance can be improved by performing the stroke.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.
