The washing machine according to the present invention is installed so that the dehydration tank 56 is suspended by four hook members 54a and dampers 54b inside the case 52, as shown in FIG. The washing tank 58 is rotatably installed inside the washing tank 58, and the washing blade 60 is rotatably installed on the bottom surface of the washing tank 58, and the washing tank 58 and the washing wing below the dehydrating tank 56 are disposed. A clutch 62 and a motor 64 for selectively rotating 60 are provided.

Here, a ring-shaped auto balance mechanism 68 is installed at an upper portion of the washing tub 58 to prevent the washing tub 58 and the dehydration tank 56 from colliding due to an imbalance when the washing tub 58 is rotated.

In addition, the upper side of the auto balance mechanism 68, that is, the upper part of the dehydration tank 56, the washing water between the dehydration tank 56 and the washing tank 58 when the washing tank 58 rotates as shown in FIG. Is raised by, a ring-shaped tub cover 66 for guiding the upper and lower double spray to the washing water is thus raised to the upper portion of the washing tub 58 is installed.

In particular, the tub cover 66 has a ring-shaped upper cover 66a having an outer circumference fixed to an upper inner circumference of the dehydration tank 56 as shown in FIGS. 4 and 5, and the upper cover 66a. An inner circumference is connected to the inner circumference of the upper cover 66a by a connecting portion 66b so that the inner circumference is horizontally installed on the lower side of the upper cover 66a, and the outer circumference of the ring-shaped row is installed to have a predetermined distance from the inner surface of the dehydration tank 56. A plurality of injection holes 66h formed in the connecting portion 66b to allow the washing water introduced between the air cover 66c and the upper cover 66a and the lower cover 66c to be sprayed onto the washing tub 58. Is made of.

That is, the upper cover 66a, the connecting portion 66b, and the lower cover 66c are connected to each other to form the tub cover 66.

Here, the inner circumference of the upper cover 66a and the inner circumference of the lower cover 66c are connected to each other by the connecting portion 66b, and the inner circumference of the upper cover 66a is the inner circumference of the lower cover 66c. It is formed to protrude further into the dehydration tank 58 than the circumference, and the connecting portion 66b is formed to be inclined upward to connect the inner circumference of the upper cover 66a and the inner circumference of the lower cover 66c.

In the connection portion 66b formed as described above, a plurality of injection holes 66h are formed at equal intervals in the circumferential direction.

In addition, a plurality of reinforcing ribs 67a vertically formed between the upper cover 66a and the lower cover 66c are arranged at equal intervals in the circumferential direction, and the reinforcing ribs 67a are extended by the washing tank. It is a straight line meeting the rotation center line of (58).

Accordingly, the reinforcing rib 67a not only reinforces the strength of the upper cover 66a and the lower cover 66c, but also washes the wash water introduced between the upper cover 66a and the lower cover 66c. It guides to the injection hole 66h side.

In addition, the lower cover 66c has a plurality of guide ribs 67b protruding downward to guide the washing water flow on the lower surface thereof at equal intervals in the circumferential direction.

The guide rib 67b may be formed to be curved in the rotational direction of the washing tub 58 and may be sprayed to the upper portion of the washing tub 58 so as to bend the flow of water that is raised by the centrifugal force of the washing tub 58.

Of course, the guide rib 67b may have a straight line shape so that the extension line meets the rotation center line of the washing tub 58.

Looking at the operation of the present invention configured as described above are as follows.

First, the washing water is supplied into the washing tank 58 and the dehydrating tank 56, and the washing tank 58 and the washing blade 60 are selectively rotated by the operation of the clutch 62 and the motor 64 to wash and rinse. Administration takes place.

At this time, the washing water between the washing tank 58 and the dehydrating tank 56 is guided by the tub cover 66 installed on the upper part of the dehydrating tank 56 while the washing water is elevated by the centrifugal force and circulated to the upper part of the washing tank 58 again. do.

Specifically, a part of the washing water rising along the inner surface of the dehydration tank 56 is introduced between the upper cover 66a and the lower cover 66b and guided by the reinforcing rib 67a to allow the washing tank 58. Is sprayed straight to the top of the

Then, the remaining wash water that has risen along the inner surface of the dehydration tank 56 is guided along the lower surface of the lower cover 66c to guide ribs 67b formed on the lower surface of the lower cover 66c. It is sprayed to be bent to the upper portion of the washing tank 58 by.

At this time, the wash water is introduced between the upper cover (66a) and the lower cover (66c) or guided by the lower surface of the lower cover (66c) is sprayed up / down the upper portion of the washing tank 58, the The washing water guided along the lower surface of the lower cover 66c is sprayed to the circumferential side of the washing tank 58, and the washing water introduced and guided between the upper cover 66a and the lower cover 66c is the washing tank ( 58 is sprayed evenly over the front side of the washing tub 58 by being sprayed to the center side.

When the washing and rinsing strokes are completed while the washing water in the washing tank 58 and the dehydrating tank 56 is circulated as described above, the washing tank 58 and the washing blade 60 are integrally rotated to dehydrate the laundry. do.

Meanwhile, the tub cover 86 has a plurality of reinforcing ribs 86b installed vertically to connect the upper cover 86a and the lower cover 86c having a ring shape as shown in FIG. 6. The extension line of the molten rib 86b is formed in a straight line to face the center of the tub cover 86 and is fixedly installed on the upper part of the dehydration tank 56.

Of course, the wash water introduced between the upper cover 86a and the lower cover 86c is guided by the reinforcing rib 86b, and the wash water passes through the end of the adjacent reinforcing rib 86b. Is sprayed to the top of the.

In addition, a plurality of guide ribs 86d protruding downward from the lower cover 86c are also arranged at equal intervals in the circumferential direction.

Therefore, when the washing tank 58 rotates, the washing water between the washing tank 58 and the dehydrating tank 56 is raised by the centrifugal force to flow into the upper cover 86a and the lower cover 86c, or the lower Guided along the lower surface of the cover (86c) is sprayed up / down the upper portion of the washing tank (58).

Washing water circulator of the washing machine according to the present invention configured as described above dewatering the tub cover for guiding the water flow of the washing water between the washing tank and the dehydration tank by the centrifugal force up and down to the upper side of the washing tank when the washing tank rotates Since it is installed in the upper part of the bath, the washing water is doublely sprayed from the upper side of the washing tank to form various washing water streams, and the washing water is sprayed evenly over the front of the washing tank, thereby improving washing and rinsing performance.
