As described above, by inputting the washing conditions, such as washing course, water supply selection, gender, age, skin conditions by operating a plurality of function buttons (36-50) provided in the operation panel 30, the operation / stop button 52 In step S2, the control means 104 determines the optimal washing administration (eg, rinsing time or rinsing time) and detergent amount according to the gender (woman), age (20s) or skin condition (sensitivity). Determine as follows.

For example, suppose the amount of laundry is the same.

① If the reference value for men in their 20s is set to {the number of rinses is A (2 times) and the amount of detergent is B (10 g)},

② Rinsing frequency A + α (α = 1) and detergent amount B-α (α = 1)

③ For women in their 20s, rinse cycle A, detergent amount B-α (α = 1)

④ For boys, rinse cycle A + α (α = 1), detergent amount B + β (β = 2)

⑤ Rinse frequency A + α (α = 1) and detergent amount B for female children

⑥ For infants, rinse cycle A + β (β = 2), detergent amount B-β (β = 2) ...

As described above, the control means 104 stores the washing stroke and the amount of detergent suitable for sex, age or skin condition on the ROM table.

Subsequently, in step S3, the control means 104 outputs a control signal to the water supply valve driving means 106 so as to feed the washing water 5 into the washing tank 5 required for sensing the amount of laundry put into the dewatering tank 7.

Therefore, the water supply valve driving means 106 receives the control signal output from the control means 104 to open (on) the water supply valve 19 so that the wash water of hot or cold water supplied from the water supply means 17 is washed. It is watered in (5).

At this time, in step S4, the water level is detected by the water level detecting means 108 by the water supply operation according to the opening of the water supply valve 19 and outputs to the control means 104, which increases the pressure as the washing water is supplied. When the frequency of the frequency oscillator circuit inside the water level sensor is lowered according to the principle that the control unit 104 receives a change in the water level of the washing water.

Accordingly, it is determined whether the water level detected by the water level detecting means 108 is supplied to the preset water level (washing water level required to detect the amount of laundry) set in advance in the control means 104, and the water supply to the water level is set. If not (NO), the flow returns to the step S3 and the water supply valve 19 is opened until the set water level is reached, and the water supply is continued, and the operation of step S3 or less is repeated.

As a result of the determination in step S4, if water is supplied up to the set water level (YES), the control means 104 controls the water supply valve driving means 106 to close (off) the water supply valve 19, A control signal is output to the washing motor driving means 110 to drive the washing motor 11.

Accordingly, an AC current is supplied from the AC input terminal to the washing motor 11, and the washing motor 11 is rotated left or right, so that the pulsator 9 is left and right reversed so that water flow is formed in the wash water supplied to the washing tank 5. The washing water in the water is absorbed by the laundry (load), the washing water level is lower than the set water level according to the amount of laundry, wherein the frequency change amount according to the amount of water level change is lower depending on the amount of laundry.

Accordingly, in step S6, the control means 104 determines the time when the washing motor 11 is reversed left and right by a built-in counter to determine whether a predetermined time (time required for determining the amount of laundry) has elapsed. If the predetermined time has not elapsed (NO), the process returns to the step S5 and the operation of step S5 or less is repeated while the washing motor 11 is left and right stirred continuously for a predetermined time.

As a result of the determination in step S6, when a predetermined time has elapsed (YES), the control means 104 controls the washing motor driving means 110 to stop left and right stirring of the washing motor 11. After the measurement, the amount of load (load) is determined by sensing the amount of change of frequency at this time.

Subsequently, in step S8, the control means 104 determines the optimum washing water level suitable for the amount and type of the laundry, and in step S9, the control means 104 supplies water to the washing water in the washing tank 5 according to the determined washing water level. The control signal is output to the valve driving means 106.

Therefore, the water supply valve driving means 106 receives the control signal output from the control means 104 to open (on) the water supply valve 19 to wash the hot or cold water supplied from the water supply means 17 in the washing tank. It is watered in (5).

At the same time, in step S10, the control means 104 outputs a control signal to the detergent injection driving means 114 to supply the powder detergent into the washing tank 5 in accordance with the determined detergent amount.

Accordingly, the detergent injecting means 114 receives the control signal output from the control means 104 to drive the detergent injector 20 to the gender (woman), age (20s), skin condition (sensitivity). The amount of detergent thus determined is introduced into the washing tank 5.

When the determined amount of detergent is added to the washing tank 5 and the washing water is completed to the determined washing water level, the flow proceeds to step S11, whereby the control means 104 closes (off) the water supply valve 19 and turns off the washing motor 11. The control signal is output to the washing motor driving means 110 to rotate.

Accordingly, the washing motor driving means 110 receives the control signal output from the control means 104 and rotates the washing motor 11 at RPM or on / off time determined according to gender, age or skin condition, thereby washing the laundry. The rotational force by the driving of the motor 11 is transmitted to the power transmission device 15 through the belt 13, the pulsator 9 by the rotational force of the washing motor 11 transmitted to the power transmission device 15. Is left and right reversed to form a stream of water in the wash water.

The water flow formed along the left and right sides of the pulsator 9 is applied to the wash water to separate the adsorbed laundry or the foreign matter, thereby washing.
