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

1A, 1B, 1C, and 1D are views illustrating a washing mode according to the present invention. In general, a washing machine includes a washing tank 12 rotatably installed inside a storage tank 11 in a main body 10. In the lower center of the washing tub 12, a pulsator 13 that rotates during washing is installed.

In addition, the washing tank 12 and the pulsator 13 penetrate through the dehydration shaft 15 and the washing shaft 16 of the clutch 14 installed in the center of the bottom surface of the water storage tank 11, respectively, and the water storage tank ( A motor pulley 18 and a clutch pulley 19 are installed in the motor 17 and the clutch 14 which are mounted on one side of the bottom of the 11 and driven by a control signal of a microcomputer (not shown), respectively. The V-belt 20 is wound between the 18 and the clutch pulley 19 so as to transmit power.

In the washing operation control of the washing machine as described above, when the quantity of laundry or the like put into the washing tank 12 is determined, the washing water flow and the detergent and the total washing time are set according to the quantity, and then the pulsator is accompanied by the total washing time. The washing stroke is performed by vortexing water through the reverse rotation of (13) to separate the stains on the laundry by friction with the laundry.

Next, when the washing stroke is completed, the turbid washing water in the washing tank 12 is discharged, and new water is supplied to the washing tank 12 to perform a rinsing cycle for rinsing for a predetermined number of times. When the rinsing stroke is completed, the water in the washing tank 12 is discharged, and the motor is rotated at a high speed to remove the laundry by centrifugal separation.

FIG. 1A illustrates a first mode for determining a washing set water level according to the present invention. The laundry to be washed is put into the washing tank 12 and the washing tank and the pulsator 12 and 13 are in a state in which no washing water is available. And when rotating the laundry integrally, by measuring the time it takes for the motor to rotate one by one to sense the amount of laundry put into the washing tank (12). At this time, when the amount of the laundry is large, the time required for one revolution becomes long.

Figure 1b shows a second mode of performing the core in accordance with the present invention, while the washing tank and the pulsator 12 and 13 integrally with the laundry while slowly rotating at the same direction / the same rotational speed of the water supply valve 21 The water is supplied to drive the washing water so as to quickly and uniformly penetrate the laundry. At this time, the rotational speed of the wash water and the pulsator 12 and 13 is rotated at a low speed so that the centrifugal force does not occur in the laundry, and can be reversed side to side, but there is no wash water circulated through the pumping channel (not shown).

Figure 1c shows a third mode according to the present invention, by washing the washing tank and the pulsator (12 and 13) integrally left and right by driving the inner wall of the washing tank and the projection of the upper end of the pulsator (13) The dirt of the clothes is removed by friction between the washing tank and the laundry due to the rotational flow of the pulsator 12 and 13. At this time, since the third mode has a faster reversal speed than the second mode, the washing water is separated from the washing tank and the pulsator 12 and 13, and the frictional force of the pulsator 13 is difficult to transfer. The frictional force is transmitted to the laundry so that uniform washing is possible.

FIG. 1D illustrates a fourth mode according to the present invention, in which the pulsator 13 is inverted left and right to drive the pulsator 13 and the pulsator 13 is generated by friction between the protrusions of the upper end of the pulsator 13 and the laundry. The friction between the laundry by the swirling water to remove the dirt of the clothing.

2A and 2B are graphs illustrating a washing administration method when the washing set water level is below the reference level and when the washing set water level is above the standard water level, and FIG. 3 is a graph illustrating the washing administration method of the washing machine as a whole. .

The washing administration method of the washing machine according to the present invention will be described with reference to the graphs and flowcharts shown in FIGS. 3 and 4 as follows.

First, in the first step, the washing machine is initialized by applying power to the washing machine, the laundry is put into the washing tub 12 of the washing machine, and the user inputs the washing conditions desired by the user through a key input unit (not shown) and turns on the operation button. (See S1)

The second step detects the quantity of water by measuring the time it takes for the motor to rotate one by using the first mode in which the washing tank, the pulsator 12 and 13 and the laundry are rotated in the absence of the washing water, and the detection result According to the washing set water level H2. In this case, the quantity of gas is sensed by driving the pulsator 13 inverted left and right, and when the amount of the laundry is large, the time required for one rotation of the motor becomes long (see S2).

In the third step, the washing tank and the pulsator 12 and 13 are integrally rotated with the laundry at a low speed such that centrifugal force is not generated at the same direction / same rotational speed, and at the same time, the water supply valve 21 is driven to supply water. By using the 2 mode, the washing water is quickly and uniformly infiltrated into the laundry in the initial stage of washing so as to carry out the foaming (see S3).

In the fourth step, the water is supplied to the detergent dissolution water level (H1) of the washing machine arbitrarily set through the water supply valve (21) and the detergent is introduced, and when the washing water reaches the detergent dissolution water level (H1) In the fifth step, the water supply is stopped, and in the sixth step, it is determined whether the washing water supplied to the washing tank is higher than or equal to the preset water level in the washing machine (see S4, S5, and S6).

If the determination result of the sixth step (S6) is affirmative, in the seventh step to dissolve the detergent introduced in the fourth step (S4) using a fourth mode for driving the pulsator 13 inverted left and right, If the determination result of the sixth step S6 is negative, in the eighth step, the detergent is dissolved using a third mode in which the washing tank and the pulsator 12 and 13 are driven inverted left and right integrally (see S7 and S8).

In the ninth step, it is determined whether the detergent dissolution process of the seventh or eighth step (S7 or S8) has passed the detergent dissolution time T1 preset in the washing machine to determine the seventh or eighth step (S7 or S8). If the result is negative, the detergent dissolution process is continued until the detergent dissolution time T1 has elapsed, and when the detergent dissolution time T1 has elapsed, in the tenth step, the washing set water level (H2) determined in the second step (S2) is reached. Water is supplied to the washing tank 12 to reach the washing water level (see S9 and S10).

In the eleventh step, it is determined whether the washing water reaches the washing set water level H2. If the determination result is negative, water is supplied until the washing water level reaches the washing set water level H2. If the result of the determination is affirmative, it is determined that the water supply is completed and the water supply is stopped in the twelfth step (see S11 and S12).

In the thirteenth step, the main washing process is performed by washing the laundry using a fourth mode for driving the pulsators 12 and 13 inverted left and right, using the projections on the upper end of the pulsator and the friction of the laundry and the vortices generated by the pulsator. In step 14, the main washing process of the thirteenth step is determined whether the preset washing setting time T2 has passed. If the result of the determination is affirmative, it is determined that the washing operation is completed. In the fifteenth step, the pulsator 13 Stop driving and end the washing process (see S13, S14, S15).

When the washing cycle is finished, the user performs a rinsing stroke and a dehydration stroke after a set or preset series.

The washing administration method of the washing machine of the present invention configured as described above is optimal by operating the setting of the washing mode when the detergent dissolving drive mode is changed according to the washing water level supplied to the washing tank and setting the optimum washing driving pattern according to the conditions under which the washing administration is performed.
