Referring to the operation of the washing machine according to the prior art configured as described above are as follows.

First, the user turns on the washing machine and inputs a washing instruction through the key input unit.

Subsequently, the system microcomputer recognizes the washing instruction input from the user, reads the washing program from the internal ROM, and drives the motor and various loads to perform washing, rinsing, and dehydration.

In detail, the water supply valve is driven according to the control signal of the system microcomputer to perform water supply up to a preset washing level.

When the washing water level is reached, the water supply is stopped and the washing operation is performed for a preset washing time by stirring the pulsator left and right.

After the washing time has elapsed, the washing operation is terminated, and then rinsing and dehydration are performed according to the control signal of the system microcomputer.

The display unit displays the current administrative progress state.

As described above, the washing machine according to the related art performs water supply during the washing stroke to drive only the pulsator to perform the washing stroke when the set washing water level is reached, so that detergent dissolution is not normally performed and uniform washing is performed on the washing cloth. There was a problem of lowering the washing performance due to the cause such as not.

The present invention has been made to solve the problems according to the prior art as described above, an object of the present invention is to provide a washing administration control method of the washing machine to perform the washing administration more effectively.

Washing stroke control method of the washing machine according to the present invention for achieving the above object in the washing machine equipped with a washing tank and a pulsator, controlling the washing stroke in the first mode and through the washing stroke in the first mode Setting a first wash level; Controlling the washing operation by the second mode; Stopping water supply when the current washing water level due to the second mode reaches a preset second washing water level; Controlling the washing operation for a first preset time set by the third mode; Performing water supply when the first set time elapses; Stopping the water supply when the current washing water level through the water supply reaches the first washing water level; And, it characterized in that it comprises the step of controlling the washing administration for a second predetermined time set by the third mode.

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

Since the configuration of the washing machine according to the present invention is the same as the above-described prior art, the description thereof is omitted.

The present invention is to add a detergent dissolving stroke to detect the amount of water to set the appropriate level of washing before performing the full-scale washing administration, the washing bag to ensure that the washing water is sufficiently put into the laundry cloth, the detergent is dissolved quickly The features of the invention differ from the prior art.

1 is a flow chart illustrating a washing stroke control method of a washing machine according to the present invention, Figure 2 is a view showing a time chart of the washing stroke of the washing machine according to the present invention.

First, a user inputs a laundry cloth, inputs a washing command, and then inputs an operation key.

As shown in the drawing, when the washing administration starts according to the washing instruction input by the user, the washing administration is controlled in the first mode (S10).

The first mode is a mode in which the laundry cloth, the washing tub, and the pulsator are integrally rotated in a state where there is no washing water, and the washing stroke according to the first mode is a stroke for detecting the amount of water.

At this time, the time required to rotate per rotation through the first mode is measured. If the laundry amount is large, the required time becomes long.

In addition, the first washing water level is determined by detecting the time required for rotation according to the detected washing quantity (S11). Here, the determined first wash level is stored in the system microcomputer.

Next, the washing operation is controlled in the second mode (S12).

In this case, the second mode is a mode in which the water supply valve is driven while driving the washing tank and the pulsator integrally with the washing cloth at the same direction / rotation speed to supply water to a preset second washing water level. The washing administration according to the second mode is a washing bag filling stroke for sufficiently injecting washing water into the washing cloth.

In detail, the washing water can be quickly and uniformly penetrated into the laundry cloth while performing the water supply to the second washing water level during the second mode, and the rotational speed of the washing tank and the pulsator is centrifugal force on the laundry cloth. This is a low speed that does not occur.

Then, it is determined whether the current washing water level through the water supply during the second mode has reached the second washing water level (S13).

As a result of the determination (S13), when the current washing water level reaches the second washing water level, the water supply is stopped (S14). On the other hand, if the current wash water level does not reach the second wash water level, the washing administration in the second mode is continued.

Next, the washing operation is controlled in the third mode (S15). In this case, the third mode is a mode for performing left and right stirring of the pulsator only.

Then, it is determined whether the first preset time has elapsed (S16). When the first preset time elapses, the determination result (S16) is performed again to supply water through the water supply valve (S17).

The washing administration in the third mode during the first set time described above is a stroke for effectively dissolving detergent introduced from the outside.

It is determined whether the current washing water level through the water supply reaches the first washing water level (S18).

If the current wash water level reaches the first wash water level, the determination result (S18) stops the water supply (S19). On the other hand, the water supply continues if the first wash water level is not reached (S18). .

Subsequently, the washing operation is performed by the third mode for the second preset time (S20). Then, it is determined whether the second set time has elapsed (S21). When the second set time has elapsed, the determination result (S21) ends the washing administration and performs rinsing or dehydrating according to the washing instruction.

The washing stroke in the third mode during the second set time is a washing stroke in earnest, and the left and right stirring of the pulsator is performed to cause friction between the washing cloths caused by the swirling water generated in the pulsator, and the protrusions on the upper pulsator. Due to the friction between the laundry cloth is a laundry administration to remove the dirt.

In this case, the second set time is relatively larger than the first set time.

The laundry administration according to the present invention described above has a time chart as shown in FIG.

Therefore, after the laundry cloth is put into the washing machine, the washing amount is first detected through the first mode to determine an appropriate washing level, and the washing water is uniformly added to the laundry cloth while the water is supplied through the second mode.

And, it has a detergent dissolution stroke for a predetermined time so that the detergent can be dissolved quickly and effectively through the third mode. Finally, the water supply is again performed up to the washing water level determined by the detection of the quantity of water through the first mode, and the washing operation is performed in earnest by the third mode.

Washing stroke control method of the washing machine according to the present invention described above has the effect of improving the washing performance by having each washing stroke for the detection of the amount of water, the core, the detergent dissolution before the full-fledged washing administration.

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.
