The present invention relates to a washing machine, and particularly, to mix washing water with a dry cleaning detergent solution to be introduced into a washing tank, and also to stir to close to neutral without causing damage, shrinkage or deformation to delicate clothes such as silk and wool. The present invention relates to a dry cleaning method of a washing machine that repeats water supply and drainage, and adds or deletes a dehydration process between water supply and drainage according to the type of cloth to allow underwater dry cleaning.

As shown in FIG. 1 of the accompanying drawings, a conventional washing machine is installed at a lower side of an outer case 1 to generate power and a washing motor 9 and a V-belt 10 to power the washing motor 9. Receives through the clutch (8) for converting the rotation and torque suitable for washing and dehydration, and the washing is made when washing the garment, and when dewatering is rotated by the rotational power transmitted from the clutch (8) Washing tub 3 for dehydration and washing installed in the tub 3 to stir and rotate by the power converted by the clutch 8 to vortex the water supplied to the tub 3 to perform washing. The wing 7 and the laundry outer tank 2 for collecting the residual water dehydrated from the laundry by the rotation dehydration action during the rotational dehydration action of the washing inner tank 3 and drained through the drainage hose, and the washing inner tank 3 When buffering washing outer tub (2) to shake according to the quantity of washing And a support rod 6 for supporting the outer case 1, a key operating plate 5 installed on the front of the outer case 1, for selecting and inputting various function keys, and the key operating plate 5; System control means (11) for inverting and driving the washing motor (9) according to the various function key signal selected through the washing machine and the washing machine (3) is installed on the upper side of the outer case (1) It consists of a water supply valve 12 which supplies washing water to the.

As described above, the conventional washing machine configured to put the laundry to be washed first into the washing tub 3 in the outer case 1, sets the washing administration and washing time through the key operation panel 5, and presses the washing start key. (11) turn on the water supply valve (12) to detect the quantity of the laundry put into the washing tub (3) to supply a small amount of washing water to the washing tub (3) and then when a small amount of washing water is supplied to the washing motor (9) is driven for a predetermined time and when a certain time elapses, the power applied to the washing motor (9) is cut off.

At this time, the washing motor (9) is stopped even though the operating power is cut off without being stopped immediately by the inertial force of rotation to stop the speed.

That is, if the washing tank 3 has a large quantity, the rotation of the washing motor 9 is stopped more quickly because the friction between the washing blade 7 and the laundry increases, and the less the laundry, the less the friction the washing motor 9 The rotation of is gradually reduced.

Based on this principle, the excitation voltage generated by the rotational inertia of the washing motor 9 is detected by the quantity detecting means (not shown), and the waveform is shaped and inputted to the system controller 11.

The system control unit 11 determines that the number of the laundry (capacity) is large and small by the number of waveforms obtained by shaping the vehicle shape in the quantity detecting means.

As described above, when the amount of water is detected, one of the high and low water levels is set according to the detected amount of water, and the washing water is supplied to the washing tub 3 through the water supply valve 12 and the detergent is introduced.

Thereafter, the washing water level supplied to the washing tub 3 is sensed through a water level detecting means (not shown in the drawing). When an appropriate water level is detected according to the quantity of water, the water supply valve 12 is turned off and the washing motor ( 9) is inverted for a certain time.

That is, for a predetermined time, the washing motor 9 is rotated clockwise and rests for a predetermined time, and then rotates counterclockwise.

As such, when the washing motor 9 is continuously and repeatedly driven clockwise, at rest, and counterclockwise, the rotational force is converted into an appropriate rotation speed and torque through the clutch 8 and transferred to the washing blade 7. Will be.

The washing blade 7 is stirred by the rotational force through the clutch 8 to vortex the washing water of the washing tub 3.

At this time, the system control unit 11 again washes the water through the water level sensing means after the washing blade (7) after the stirring movement for a predetermined time to detect whether the wash water level is appropriate again in the state that the wash water soaked into the laundry It is detected whether the water level in (3) is appropriate.

If the water level is not directly connected to the water level according to the quantity of water, open the water supply valve 12 to supply the washing water to the washing tank 3 to an appropriate level, and if the water level is appropriate, the washing motor in the same manner as described above for the set washing time. The washing blade 7 is stirred through the (9).

When the washing blade 7 is stirred, the wash water is vortexed, and friction occurs between the wash water and the laundry, and washing proceeds.

As such, when the washing is completed for a certain time, the normal rinsing process is performed.

That is, the system control unit 11 in the rinsing process first opens the drain valve to drain the turbid water stored in the washing tank 3 and the washing tank 2, and dehydration proceeds to remove only the water of the laundry when the draining is completed. Will be

Then, when dehydration is completed, close the drain valve and open the water spit 12 to supply the washing water to the washing tub 3, and rinse the laundry by stirring the washing blade 7 through the washing motor 9 for a predetermined time. After a certain time elapses, the drain valve is opened again to drain the turbid water from the washing inner tank 3 and the outer tub 2 to search for adequacy of rinsing with turbidity of the washing water.

If the searched side and rinsing are not straight, that is, the turbidity of the wash water is severe, the process is repeated several times until the rinsing is satisfied through the process after the draining process in the rinsing process.

And if the rinsing is appropriate in the above by rotating the washing tub (3) at a high speed through the washing motor (9) and the clutch (8) to completely remove the water leaking in the laundry to complete all the processes of washing.
