The conventional fully automatic washing machine configured as described above puts laundry and detergent in the washing tub 3, selects the operating conditions of the operation unit 13, and operates the washing machine. Then, the tap water of the tap water 17 is washed through the water supply hose 19. When the washing water supplied into the outer tub 2 and the washing water supplied in the washing tub 2 reaches an amount necessary to wash the laundry put into the washing tub 3, the driving means is driven so that the washing blade 5 rotates forward and reverse. Then, water flow is formed in the washing tub 3 to wash.

That is, as the washing blade 5 rotates, the washing water introduced into the washing tub 3 rises at the edge of the washing blade 5 and forms a water flow down and down to the center of the washing blade 5 to wash. . At this time, the water flow of the bottom portion of the washing inner tub 3 is pushed toward the inner circumferential surface of the dehydration tank 3 by the rotational force of the washing blade 5 to rise through an unillustrated flow path of the seams collector 9. By pouring down to the center part through the bag 9a, the washing | cleaning waste is filtered at the same time to improve washing effect.

In the washing machine comprising a, the balance is not formed ribs on the upper side, the tub cover is protruded to the balancer in the inner direction of the washing tub while the protruding end does not interfere with the water flow between the balancer and the tub cover It is formed so as not to bend toward the balancer.

On the other hand, according to a feature of the laundry prevention method of damage according to the present invention, a level determination step of detecting the amount of raisins filled in the washing tank and determining the set water level according to the detected amount of raisins; A washing administration initial step of performing a washing stroke after performing water supply by the set water level according to the level determination step; A centrifugal washing step of repeatedly performing centrifugal washing once and left to perform drainage to the set water level and preventing the laundry from floating to the upper part of the washing tank when the washing administration step is completed; After the centrifugal washing step is completed, the washing step is performed after the drainage to the air level, and the dehydration is performed.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a view showing in detail a balancer and a tub cover, which are some components of the laundry damage preventing apparatus according to the present invention, and FIG. 4 is a flowchart illustrating a laundry preventing method according to the present invention.

First, referring to FIG. 3, in the present invention, the ribs, which are previously installed on the upper side of the balancer, are removed between the balancer 17 and the tub cover 18 to prevent the laundry from floating to the upper side of the washing tank by buoyancy. Cannon water can be implemented by permeation washing.

In addition, the tub cover 18 also protrudes to a length similar to that of the balancer 17 inside the washing tank unlike the existing one, and the protruding end thereof does not prevent water flow between the balancer 17 and the tub cover 18. It is characteristic that it is bent toward the balancer 17 so that it may not.

Next, referring to FIG. 4, in the first step, the system detects the amount of raisins filled in the washing tank before starting the washing operation (see S1), and in the second step, the amount of raisins detected in the first step S1. The initial set water level is determined according to (see S2).

In the third step, water supply is performed according to the initial set water level determined in the second step S2 (see S3), and in the fourth step, the water level in the current washing tank is changed to the third level through the third step S3. It is determined whether the set water level determined in step 2 is reached (see S4).

In this case, when the determination result of the fourth step S4 is YES, the washing operation proceeds in the order of washing, rinsing, and dehydration in the fifth step, but the determination result of the fourth step S4. If NO, the flow returns to the third step S3 and continues to supply water so that the washing water is filled in the washing tank by the initial set level (see S5).

Meanwhile, in the sixth step, it is determined whether the washing is completed as a result of the washing operation in the fifth step (S5) (see S6), and in the seventh step, the determination result of the sixth step (S6) is YES. In case of, the washing water in the washing tank is drained to the set water level level (see S7).

When the determination result of the sixth step S6 is no, the process returns to the fifth step S5 to continue the washing operation to complete the washing.

In the eighth step, it is determined whether the result of the drainage in the seventh step S7 corresponds to the set water level determined in the initial second step S2 in the current washing tank (see S8). If the determination result of the eighth step (S8) is YES, centrifugal washing is repeatedly performed once and left to lower the laundry floating to the upper part of the washing tank by buoyancy to prevent the damage of the laundry. If the determination result of the eighth step S8 is no, the drainage is continued until the water level in the washing tank reaches the initial setting level.

Particularly, in the ninth step, when the light and bulky laundry floats upward due to buoyancy during washing, a rib is installed between the tub cover and the balancer to cause damage to the laundry, but in the present invention, the rib is a balancer (17). And the tub cover 18 are removed, so that the cannon flesh is realized by centrifugal permeation washing.

In the tenth step, it is determined whether the centrifugal washing has been completed in the ninth step (S9) (see S10), and if the determination result of the tenth step (S10) is YES, the eleventh to the airborne level are determined. The drainage is performed (see S11). If the determination result of the tenth step S10 is no, the centrifugal washing of the ninth step S9 is completed.

In the twelfth step, it is determined whether the current water level in the washing tank is an empty water level through the drainage of the eleventh step (S11) (see S12), and if the determination result of the twelfth step (S12) is YES, In step 13, all the washing operations are completed after the dehydration stroke (see S13). However, if the determination result of the twelfth step (S12) is no, drain until the water level in the washing tank becomes the air level. After proceeding to go to the thirteenth step (S13) to complete the washing operation.

As such, when all the washing strokes are completed, the washing cycle is completed by repeating the water supply, rinsing, draining, and dehydrating a predetermined number of times, and performing the dehydrating stroke after the draining at the last rinsing, thereby completing all the washing strokes.

Laundry damage prevention device and method of the present invention configured as described above is performed centrifugal washing once and left to prevent the laundry from floating by buoyancy instead of removing the rib installed between the balancer and the tub cover. By doing so, the laundry is not caught between the balancer and the tub cover, so that the laundry can be reliably prevented and the damage of the tub cover can be prevented.
