Characteristic of the present invention is the first step of setting the washing water level according to the amount of washing cloth, and the water level in each water supply step of the predetermined washing time and the water flow pattern is performed according to the washing water level for each water supply step in a multi-stage The washing step and the water flow pattern corresponding to the second step of performing the washing.

Another feature of the present invention is the first step of setting the washing water level according to the amount of laundry, and if the washing water level is lower than the reference level, the second step of performing the washing by supplying water to the washing water level, if the washing water level is higher than the standard water level washing And a third step of performing water washing to a water level-2 level or a washing water level-1 level to perform friction washing or shaking washing, and water supply to a washing water level to perform an unwashing.

Hereinafter, a washing stroke control method of a washing machine according to the present invention with reference to the accompanying drawings.

3 is a flow chart illustrating a washing operation according to the present invention, Figure 4 is a view showing a detailed washing program of the present invention, Figures 5a to 5c is a view showing a step-by-step washing method of the present invention and Figure 6 is a laundry of the present invention The figure which shows the performance improvement effect.

In the laundry administration according to the present invention, as shown in FIG. 3, when the user inserts the laundry cloth into the washing tank 4 and presses an operation key, the washing amount of the laundry cloth is sensed and the water level (washing water level) is set accordingly (S101). .

Subsequently, when the washing level is set to one of the low level group, that is, the minimum level, the small level, or the small low level, washing is performed by supplying water to the corresponding level, i.e., the minimum level, the small level, and the small low level at once. do.

For example, when the washing water level is set to a small water level (S103), water is supplied to the small water level at once (S114) and washing is performed for 9 minutes in an A pattern (S117).

And when the washing water level is set to one of the low water level group, that is, the low water level or the low water level, water supply and washing are performed in two stages. Water wash to wash level once more.

For example, if the washing water level is set to a low water level (S106), first, the water level is 1 level, that is, water supply to the low water level (S115), friction washing is performed for 10 minutes in a C pattern (S120) water supply to the low water level (S128), the washing is performed for 5 minutes with the H pattern (S132).

Subsequently, when the washing water level is set to one of the low water level group, that is, the low water level, low water level, medium water level, medium high water level or used water level, water supply and washing are performed in three stages. Wash by watering up to 2 stages additional water supply to the water level-1 level to perform the washing again, then water washing up to 3 levels to wash again.

For example, when the washing water level is set to the medium water level (S109), the water level is supplied to the level 2 level, that is, the low and low medium water level (S116), and friction washing is performed for 12 minutes in the H pattern (S123).

At this time, the friction washing rotates the rotary blade 6 in the H pattern at the minimum water level and at the same time pumps the washing water to the cam 10 in the center of the rotary blade 6 to form a water flow as shown in FIG. At the same time, the entire washing cloth in the washing tank 4 is uniformly washed by the friction force caused by the impingement on the inner wall and the rotary blade 6 of the washing tank 4.

Therefore, friction washing is intended to achieve the same washing effect as wet rubbing with hand cloths at home.

Subsequently, additional water is supplied to the corresponding water level-1 level, that is, the low and medium water level (S129), and shake washing is performed for 5 minutes with the E pattern (S135).

At this time, the washing washing by rotating the rotary blade 6 in the E-pattern in the state where the additional washing water is additionally supplied, and at the same time by pumping the washing water to the cam 10 in the center of the rotary blade 6 to form a water flow as shown in Figure 5b Compared to this, the washing effect is reduced, but the washing operation is used to separate the reactants of the detergent and the contaminants adsorbed on the washing cloth with the added washing water while maintaining the friction washing effect above a certain level.

Therefore, you want to get the same washing effect by soaking the cloth with water and rubbing it with your hands and then again with water.

Then, water is supplied to the medium water level (S140), and annealing is performed for 5 minutes using an E pattern (S143).

In this case, the unwashing is a washing operation for completely separating contaminants from the laundry cloth by forming a water flow as shown in FIG. Since the amount of washing water in the friction washing and shaking washing is insufficient to lower the degree of contamination of the washing water due to the contaminants separated from the laundry cloth, it is intended to maximize the removal rate of the contaminants by additionally supplying water to the medium level.

On the other hand, when the washing water level is set to any one of the high water level group, that is, the high water level or the highest water level, the water is supplied to the corresponding water level-2 level and the washing is performed, and the water is supplied to the washing water level to perform the washing again.

For example, if the washing water level is set to a high water level (S112), water level up to the corresponding level-2, that is, medium to high water level (S116), and performs friction washing for 5 minutes in a J pattern (S126), water supply to a high water level By (S130), the loosening is performed for 5 minutes in the G pattern (S138).

Next, as shown in FIG. 4, the next stroke, that is, rinsing 1, rinsing 2, and dehydrating stroke are sequentially performed for a predetermined time in a predetermined water flow pattern (S146), and the entire washing process is terminated.

As described above with reference to Figure 6 showing the actual experimental value of the laundry performance improvement effect by performing the laundry as follows.

6 compares the change in reflectance, degree of cleaning, and cleaning ratio by performing washing while varying the quantity, the quality of the foam, and the washing water level using the conventional washing method and the washing method of the present invention.

At this time, the standard water level is the water level set for each washing machine model for the corresponding quantity. For example, when the washing machine capacity is 10Kg, the 30% load means 3Kg, so the standard water level is the low water level. For example, 60% load means 6Kg, so the standard water level is low and medium water level.

In addition, the standard water level + 1 and the standard water level-1 is an experimental level to cope with this, because some level setting errors may occur for the same amount during the level setting process by the fuzzy method.

And the sample means an experimental material, that is, a washing machine, "# 1, # 2" is two washing machines to show the error generated in the washing machine of the same model to which the washing method of the present invention is applied, "existing" is in the prior art Means the washing machine of the same model to which the washing method according to the.

The circular reflectance is then the reflectivity of the original uncontaminated white cloth, usually about 80-84%.

The pre-reflectivity reflects the degree of contamination of the original cloth and the post-reflection reflectance means the reflectance of the contaminated cloth after washing.

In addition, the degree of cleaning means (after-reflectance-pre-reflectance) / (foam reflectance-pre-reflectance) and the cleaning ratio means the degree of cleaning / standard washing machine cleaning, where the standard washing machine means a washing machine according to KS standards.

For example, at the 30% load of normal clothing / standard water level + 1, the cleanliness and the cleaning ratio of the sample # 1 is 0.572 and 1.040, respectively, and 0.534 and 0.971, respectively.

In addition, the cleanliness and the cleaning ratio were 0.601 and 1.092 and 0.564 and 1.026, respectively, for the sample # 1 at 60% load of strong clothing / standard water level +1. It can be seen that this improvement is significant.

Washing operation control method of the washing machine according to the present invention, as confirmed in the actual experimental value, by applying the washing pattern according to the water supply and the water level of the multi-stage washing performance is significantly improved compared to the conventional washing method, so the user's reliability will be maximized. It can be effective.
