Figure 4 is a flow chart illustrating a rinsing method of the washing machine of the first embodiment according to the present invention.

A rinsing method of the washing machine of the first embodiment according to the present invention will be described with reference to FIGS. 1 and 4.

First, the rinsing water is supplied by rinsing water while the washing tank 23 is rotated at low speed by controlling the driving motor 40 at a speed at which rinsing water can be impregnated with laundry (S ₁ ).

The reason why the washing tank 23 is rotated at a low speed is that if the rinsing water is supplied when the washing tank 23 is rotated at a high speed, the laundry is also rotated at a high speed together with the washing tank 23, so that the rinsing water splashes as it hits the laundry and rinses inside the laundry. It does not soak well.

Therefore, the washing tank 23 is rotated at a low speed so that the rinsing water can be sufficiently immersed in the laundry. At this time, the rotation speed of the washing tank 23 may vary depending on the system or water supply pressure, but the diameter of the washing tank 23 is typically 525 mm. When rotating to less than 300rpm rinse water will smoothly penetrate the laundry.

Of these, the optimum rotational speed at which the rinsing water is best impregnated in the laundry is preferably set at about 100 rpm.

In addition, the impregnation operation of the rinsing water may be implemented while gradually increasing the rotational speed of the washing tub 23 to about 300 rpm in the initial driving, without limiting the rotational speed of the washing tub 23 as described above.

In this rinsing water impregnation operation, it is preferable to set the supply amount of the rinsing water or the impregnation operation time differently according to the washing amount, and when the rinse water setting level or the impregnation setting time elapses (S ₂ ), the rinsing water discharge operation is started. .

Next, the rinsing water discharge operation drains the rinsing water while rotating the washing tank 23 at a high speed at which the rinsing water impregnated in the laundry passes through the laundry to be discharged to the outside (S ₃ ).

At this time, the water supply of the rinsing water is stopped, and the drain valve 27 is opened so that the rinsing water can be discharged.

In this rinsing water discharge operation, when the washing tank 23 is rotated at a speed higher than the speed at which the washing tank 23 rotates in the above-described rinsing water impregnation operation, the rinsing water and the rinsing water are forced out of the washing tank 23 by centrifugal force. Will generate power.

The laundry is limited to movement by hanging on the wall of the washing tank 23, but the rinsing water impregnated in the laundry is passed through the fiber network of the laundry, at which time debris, contaminants, Detach the detergent, foam and the like through the hole of the washing tank 23 to be taken out to the reservoir 21.

In this way, contaminants, bubbles, and the like, including the rinsing water that flows out of the reservoir 21 are discharged to the outside through the drain hose (26).

In the rinsing water discharging operation as described above, the rotation speed of the washing tank 23 is preferably set such that the rinsing water is increased to 200 or more rpm through the fiber network of the laundry to the rotational speed in the normal dehydration operation.

Next, when the rinsing water impregnated with the laundry is dewatered and the rinsing water discharge operation is completed, the same rinsing stroke is repeated as the set number of rinsing strokes, and when the rinsing operation of the set number of times is ended (S ₄ ), the driving motor 40 The rinsing stroke is completed by stopping the operation of the washing tank 23 and closing the drain valve 27 (S ₅ ).

Therefore, the rinsing method of the washing machine according to the first embodiment according to the present invention as described above, so that the rinsing water is impregnated in the laundry, and then drain and dewater operation immediately to perform the rinsing water in the reservoir 21 and the washing tank 23 The rinsing operation is performed without filling up to a certain level, thereby reducing the rinsing water.

In addition, the rinsing method is a water supply operation, stirring rinsing operation, drainage operation, dehydration operation is carried out at the same time without being separated can be greatly reduced the time required for the rinsing stroke.

5 is a flowchart illustrating a rinsing method of the washing machine of the second embodiment according to the present invention.

A rinsing method of the washing machine of the second embodiment according to the present invention will be described with reference to FIGS. 1, 2 and 5.

First, when the rinsing stroke is started, the rinsing water impregnation operation is performed to supply the rinsing water while rotating the washing tank 23 at low speed so that the rinsing water can be impregnated in the laundry (S ₁ ).

When the amount of rinsing water supplied to the water reservoir 21 reaches a predetermined level for circulation rinsing while performing such a rinsing water impregnation operation (S ₂ ), the water supply is stopped and the circulation rinsing operation is performed (S ₃ ). .

At this time, the motor direct drive type washing machine as shown in FIG. 1 controls the driving motor 40 to rotate the washing tank 23 at a high speed at a rotational speed at which the centrifugal circulation washing can be performed, and thus the rinsing water is stored in the water tank 21 by the centrifugal force. It is operated to rise along the wall surface and then blow into the washing tub 23 while hitting the tub cover 35.

In addition, as shown in FIG. 2, the washing machine equipped with the pump circulation device rotates the washing tank 23 'at a constant speed and operates the circulation pump 55 to circulate the rinsing water contained in the reservoir 21'. Through the 50 and the jet port 60 is ejected to the inside of the washing tank 23 'to perform a circulating rinsing operation.

In this centrifugal circulation rinsing and pump circulation rinsing operation, the rinsing water impregnated in the laundry leaves the fiber network of the laundry by the centrifugal force in which the washing tank 23 rotates, and the rinsing water is again ejected from the upper portion of the washing tank 23 again. By repeating the operation impregnated with the laundry, it is possible to more reliably separate foreign substances and detergents from the laundry to increase the rinsing power.

When the circulating rinsing operation as described above proceeds (S ₄ ), the drainage valve 27 is opened and the washing tank 23 is rotated at a high speed to drain the rinsing water and foreign substances at the same time. Water discharge operation is carried out (S ₅ ).

At this time, the rinsing water, the contaminants and the foam, etc., which have passed through the laundry to the reservoir 21 are discharged to the outside through the drain hose 26.

When the rinsing water discharge operation as described above is completed, it is determined whether the rinsing operation is performed by the set number of times, and when the rinsing stroke is performed by the set number of times (S ₆ ), the operation of the driving motor 40 is stopped to stop the washing tank 23. And the rinsing stroke is completed by closing the drain valve 27 (S ₇ ).

The rinsing method of the washing machine according to the second embodiment of the present invention operated as described above allows the rinsed water to be impregnated in the laundry, and then repeats the process of circulating the rinsing water for a predetermined time, and proceeds with drainage and dehydration. Therefore, even using less water can improve the rinsing power of the laundry, it is possible to reduce the rinsing time.

6 is a flowchart illustrating a rinsing method of the washing machine of the third embodiment according to the present invention.

The rinsing method of the washing machine according to the third embodiment of the present invention will be described with reference to FIGS. 1 and 6 as follows.

First, the rinsing water impregnation operation is performed so that the rinsing water is impregnated in the laundry by supplying the rinsing water while rotating the washing tank 23 at low speed (S ₁ ).

After that, when the set water level or the impregnation setting time of the rinsing water has elapsed (S ₂ ), the rinsing water drainage operation is performed while opening the drain valve while increasing the rotation speed of the washing tank (S ₂ ).

At this time, the rinsing water drainage operation is performed in the state that the water supply of the rinsing water is continued, and the rinsing water permeation rinsing operation is performed while the rinsing water supplied into the washing tank 23 passes through the laundry.

Of course, in the water supply and drainage rinsing operation, the amount of rinsing water to be drained should be set larger than the amount of rinsing water to be supplied.

As such, when the amount of rinsing water drops to the set level or passes the set time (S ₄ ) in the course of the rapid drainage permeation rinsing operation (S ₄ ), the water supply is stopped, and the washing tank 23 rotates at a higher speed and drainage and dehydration operation is performed. This is done.

When the rinsing stroke operated as described above is repeated by the set number of times (S ₆ ), the washing tank 23 is stopped and the drain valve 27 is closed to complete the rinsing stroke (S ₇ ).

The rinsing method of the washing machine according to the third embodiment of the present invention, operated as described above, supplies water while the washing tank is rotated so that the rinsing water is impregnated to the laundry, and the dewatering operation is performed after the water supply and drainage permeation operation is performed while the drain valve is opened. As a result, the rinsing water can be reduced, and the rinsing power of the laundry can be improved, and the rinsing time can be reduced.

The rinsing method of the washing machine of the present invention configured and operated as described above is rinsing water because the washing tank is also rotated at the same time with the water supply so that the foam and detergent are discharged together with the rinsing water at a high speed while the rinsing water is impregnated in the laundry. This provides the advantage of reducing rinsing time while reducing rinsing time.
