The present invention will be described in detail with reference to Figs.

In the washing machine (101) having a variable speed motor (107) having a washing tub (103) having a pulsator (105) integrally formed at its bottom and a single drive shaft (106) directly connected to the tub (103),

When washing or rinsing, the washing inner tank 103 is rotated forward and backward at a high speed so that the washing water of the washing inner tank 103 is pumped to the upper portion of the washing inner tank 103 by centrifugal force and supplied to the washing inner tank 103 again. And a rinsing process.

In the washing machine 101 having a variable speed motor 107 having a washing inner tank 103 having a pulsator 105 integrally formed at its bottom and a single drive shaft 106 directly connected to the washing inner tank 103. ,

Centrifugal permeate washing in which the washing inner tank 103 is rotated forward and backward at a high speed during washing or hemming, and the washing water of the washing inner tank 103 is pumped to the upper portion of the washing inner tank 103 by centrifugal force and supplied to the washing inner tank 103 again. And rinsing process,

During washing or rinsing, the washing inner tank 103 is rotated forward and backward at a low speed, and is composed of a combination of a stirring washing and a rinsing process to perform washing or hemging.

In addition, when the direction of the centrifugal washing and hem in the forward direction to the reverse centrifugation and rinsing, the washing tank 103 is suddenly stopped so that the wash water and the laundry are rotated by inertia to wash and rinse. It will include.

Referring to the operation of the present invention as described above is as follows.

First, Figure 2 is a cross-sectional view showing a washing machine of the present invention, when the laundry is put into the washing tank 103 of the washing machine 101 and pressing the start button is a water supply administration.

When the washing water of a predetermined level is supplied to the washing inner tank 103 and the washing outer tank 102 by the water supply administration, the water supply is stopped and the washing process is performed.

And, the washing process is made by the rotation process of the motor.

That is, during the rotation of the motor, the driving shaft 106 is forward and reversed by the forward and reverse rotation of the motor 107, and the washing inner tank 103 is forward and reversed by the forward and reverse rotation of the drive shaft 106. Reverse rotation.

Therefore, the laundry of the washing tub 103 is washed by the flow of washing water by the forward and reverse rotation of the washing tub 103.

At this time, by the action of increasing the rotational force of the present invention motor 107 at a high speed or a low speed it is possible to perform a centrifugal washing and stirring washing process.

First, in order to perform the centrifugal washing process, the rotation speed of the motor 107 should be increased.

That is, as the rotation speed of the motor 107 increases, the rotation speed of the drive shaft 106 and the washing inner tank 103 also increases, so that the centrifugal force increases.

Therefore, the laundry of the washing tub 103 is in a state of being in close contact with the inner wall surface of the washing tub 103 by the centrifugal force, and the washing water passes between the laundry and the ol as shown in FIG. 3.

At this time, since the stains on the laundry are washed by the permeable washing water, the laundry is more clean.

In addition, the wash water passing through the laundry between the ol and the ol is drained to the washing tub 102 through the washing hole 104 of the washing tub 103, the washing drained to the washing tub 102 The water rises upward along the washing tub 103 and the washing tub 102 by the large centrifugal force generated by the high speed rotation of the washing tub 103.

Of course, the wash water already supplied to the bottom surface of the washing tub 102 also rises upward along the washing tub 103 and the washing tub 102 by the centrifugal force.

In addition, the washing water raised above the washing tub 103 and the washing tub 102 is supplied to the washing tub 103.

As described above, the washing water falling into the washing tank 103 from the upper side of the washing tub 103 may have a large impact on the laundry of the washing tub 103.

Therefore, since the tapping effect of the laundry can be obtained by the impact force of the washing water generated by the drop of the washing water, high washing degree can be obtained.

In addition, since the centrifugal washing process is a washing method in which the washing water is pumped up and re-supplied to the washing tank 103, much washing water is not required.

That is, in order to wash the washing water in the washing tub 103 to play the important role because the wash water of the washing tub 103 contacts the laundry, but the wash water of the washing tub 102 is virtually nothing. .

In other words, since the wash water of the washing tub 102 generates frictional resistance during the rotation of the washing tub 103, it only hinders the rotation of the washing tub 103.

Therefore, in order for the washing tub 103 to rotate smoothly, it may be considered that it is most important to maintain a small contact with the wash water of the washing tub 102.

However, in the present invention, after supplying a smaller amount (about 50%) of the wash water than the conventional washing machine to the washing inner tank 103 and the washing outer tank 102, the washing water of the washing outer tank 102 is pumped up as shown in FIG. Since washing is performed by means of re-supplying to the inner tank 103, the washing tub 103 is constructed to wash with the same amount of washing as in the prior art, while the washing tub 102 has a small amount of washing, so washing is performed. Smooth rotation of the inner tub 103 is enabled.

Therefore, it is possible to obtain a water saving effect due to the use of less wash water, to reduce the amount of detergent introduced into the wash water, and to speed up the time of water supply and drainage. Can be reduced.

On the other hand, Figure 4 is a cross-sectional view for explaining the stirring washing process by the washing machine of the present invention, in order to perform the stirring washing process, the rotation speed of the motor 107 must be lowered.

In addition, since the rotational speed decrease of the washing tub 103 generates a small centrifugal force, the washing water drained into the washing hole 104 of the washing tub 103 does not rise to the upper side, but is collected in the washing tub 102. As a result, the wash water collected in the washing tub 102 is in the same state as the water level of the washing tub 103.

At this time, the laundry of the washing tub 103 can be washed by the stirring action of the pulsator 105 integrally formed with the washing tub 103.

In addition, when the agitation washing by the pulsator 105 is made as described above, the laundry that is in close contact with the inner wall surface of the washing tub 103 during centrifugal permeation is released while being locked in the washing water of the washing tub 103. Therefore, it is possible to obtain improved cleaning degree.

In addition, the centrifugal permeation washing process and the stirring washing process may be divided into a predetermined section to perform the washing process repeatedly.

On the other hand, Figure 5 is a cross-sectional view shown to explain the restoration of the water washing by the washing machine of the present invention, by washing the inner tub 103 during the centrifugal permeation washing process can be washed by the restoration water washing process.

That is, when the rapid stop to reverse the reverse rotation during the high-speed rotation of the motor 107 or the rapid stop to reverse the reverse rotation from the reverse rotation, the wash water and the laundry of the washing tub 103 was rotated by inertia It has the property of continuing to rotate in the original direction.

In this case, the laundry hits the washing inner tank 103 and the pulsator 105 formed integrally with the washing inner tank 103 to generate a tapping effect.

Thus, even when the washing inner tub 103 is changed in direction, the restoration washing process is continuously maintained, thereby achieving improved washing performance.

When the centrifugal washing process or the stirring washing process and the restorative water washing process are completed as described above, the draining process is performed, and when the draining process is completed, the rinsing process is performed while the rinsing process is performed again. In the process, the centrifugal rinsing process may be performed, and the centrifugal rinsing process and the stirring rinsing process may be alternately performed.

Of course, when the direction of the washing inner tank 103 is changed (restored water rinsing process) is performed.

Thus, the present invention increases the rotational force of the washing tub connected to the motor and the drive shaft, and the washing water discharged through the washing tub of the washing tub is pumped up to the upper side of the tub, and then re-supplied to the tub. The washing and rinsing can be carried out, and the washing cycle can be lowered by rotating the pulsator integrated with the washing tank and the washing tank in the forward and reverse directions, thereby allowing the washing to be stirred. By restoring the washing and rinsing to ensure that the laundry and the water inside the washing tank continue to rotate in case of sudden stop,

Even with a small amount of washing water, smooth washing and rinsing can be achieved, resulting in a water saving effect.

The amount of detergent added to the small amount of wash water can also be reduced to reduce environmental pollution due to a decrease in the amount of detergent used,

By using the small amount of wash water can reduce the water supply and drainage time to reduce the overall washing time,

It has a useful effect to increase the degree of washing of the laundry by reducing the foaming and porosity rate of the laundry to be washed in the washing tank.
