In general, the washing machine has a washing tank 12 rotatably installed inside the water tank 11 in the main body 10, and a pulsator 13 that rotates during washing is installed in the lower center of the washing tank 12.

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 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 cycle 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 to perform dehydration stroke.

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).
