The rotation shaft may extend in parallel to the width direction of the body portion B, and the backflow prevention part 97 rotated about the rotation shaft may be rotated such that the rear end faces the front. That is, the backflow prevention part 97 may be rotated so as to be at least partially away from the inlet 913 about the rotation axis.

The backflow prevention part 97 having a rotating shaft formed on one side and rotating on the other side may be rotated by the force of water flowing from the outside of the body B toward the inlet 913 . That is, when water flows into the inlet 913 in a state in which the inlet 913 is blocked, the backflow prevention part 97 rotates the other side by the flow of water and the inlet 913 is opened so that the water flows into the body part (B). to allow entry into the

In addition, when the water introduced into the body (B) flows toward the inlet 913 again due to its own weight or the like, the backflow prevention unit 97 flows backwards from the inside of the body (B) toward the inlet 913 . The other side may be rotated toward the inlet 913 side by the water.

Accordingly, the backflow prevention unit 97 is in close contact with the inlet 913 again and blocks the inlet 913, thereby blocking the water inside the body B from being discharged to the inlet 913, not the outlet 941. have.

The backflow prevention part 97 is rotated to open the inlet 913 by the water flowing into the inlet 913, and to be easily rotated to shield the inlet 913 by the water flowing back from the body B, It may be arranged in an oblique shape such that one side is located below and the other side is located above.

On the other hand, referring to FIGS. 3 and 4 , in an embodiment of the present invention, the filter unit 9 rotates the drum 5 to discharge the water contained in the clothes into the tub 3 . It may further include a dehydrating unit 915 for discharging water to the outside of the body (B).

The dewatering unit 915 provided in the present invention can discharge the water contained in the foreign material in the tangential direction R of the rotation trajectory of the drum 5 . That is, the dewatering part 915 may be provided on the flange 911 forming the side surface of the inner body part 91 .

Meanwhile, FIG. 9 shows the inside of the inner body part 91 according to an embodiment of the present invention. Referring to FIG. 9 , an embodiment of the present invention is provided inside the inner body part 91 , and the water introduced through the inlet 913 flows toward the upper part of the inner body part 91 . Water that is provided inside the rising flow path part 111 and the inner body part 91, and moved to the upper part of the inner body part 91 along the rising flow path part 111, descends and flows, and the It may further include a collecting unit 200 including a collecting protrusion 211 for collecting foreign substances from the water that protrudes toward the outer body portion 94 and descends.

Specifically, as described above, in the laundry treatment apparatus according to the embodiment of the present invention, when the stirring unit 57 rotates in the drum 5 , water is filtered by the filter unit 9 provided on the inner wall of the drum 5 . and is discharged back to the drum 5 , or discharged by the discharge unit 915 and discharged back to the tub 3 .

If the above process is repeated, a significant amount of water inside the drum 5 may be introduced into the filter unit 9 and filtered by the filter unit 9 . That is, lint or foreign substances that have come off from the clothes in the water accommodated in the tub 3 may be filtered by the filter unit 9 .

However, when there is no special resistance to water inside the body part B, the time remaining in the filter part 9 for the water introduced into the filter part 9 is relatively small.

In addition, since the flow rate of the water introduced into the filter unit 9 is not reduced, the possibility that foreign substances may be deposited may be reduced, and since the foreign substances are not fixed to the body portion B, the body portion B ), when the water is introduced into the body portion (B) can be floated inside again.

There may be a possibility that the foreign material floating inside the body part B may leave the filter part 9 and re-introduce into the drum 5 . In addition, the foreign substances that cannot be fixed inside the body part B may be stacked on the lower part of the filter part 9 when all the water is drained out of the filter part 9 .

When the filter unit 9 filters the water in the drum 5 for a long time, if the foreign material is deposited only on the lower portion of the body portion B, even if the total area of the body portion B increases, the filter The amount that the part 9 can accommodate the foreign material may be limited to a certain amount.

In addition, when a foreign material is stacked near the inlet 913 , the foreign material may interfere with the inflow of water into the filter unit 9 , and in severe cases, the foreign material may escape into the inlet 913 .

Furthermore, if there is no separate flow path for guiding the water flowing into the filter unit 9 to the upper portion of the filter unit 9 or the body portion B, the water flowing into the filter unit 9 is It can be difficult to spread all over the part (9).

That is, even if the inner body portion 91 is provided on the entire surface of the body portion (B), when the inlet 913 is provided at the lower portion, most of the water and foreign substances are located in the lower portion of the filter portion (9). may stay focused.

That is, since only a portion of the water introduced from the inlet 913 reaches the upper portion of the filter unit 9 , it may be difficult to filter water and foreign substances through the upper portion of the filter body 950 .

On the other hand, if a resistance body against the flow of water is provided in the rising flow path part 111 , foreign substances may be preferentially collected in the lower part of the body part B and may not be collected in the upper part of the body part B.

That is, as time elapses, foreign substances may be stacked only on the lower portion of the body portion B, and the foreign substances may interfere with the inflow of water flowing in from the inlet 913 , and further foreign substances may enter the inlet 913 . There is a possibility that it will be discharged again.

In order to solve the above problem, as shown in FIG. 9 , in one embodiment of the present invention, an upward flow path part is provided inside the inner body part 91 and becomes a flow path for water flowing to the upper part of the inner body part 91 . (111) may be included.

The rising flow passage part 111 may be formed by a guide plate 120 provided parallel to the inner body part 91 and spaced apart from one surface of the body part B by a certain distance as shown in FIG. 3 . have.

Referring to the embodiment of the present invention shown in FIG. 3 , the guide plate 120 is provided to be spaced apart from the base 910 by a predetermined interval, and may be provided in parallel with the base 910 . As a result, the guide plate 120 may be formed with a rising flow path 111 through which water rises between the base 910 and the base 910 .

In addition, the guide plate 120 may be provided to be spaced apart from the upper end of the body portion (B) by a predetermined distance. This is to allow water to move to the upper portion of the guide plate 120 .

That is, the upper end of the guide plate 120 is the body portion B so that the water moving to the upper portion of the body portion B moves to the lower portion of the body portion B beyond the guide plate 120 . It may be spaced apart from the flange 911 provided on the upper part by a predetermined distance.

Accordingly, the water introduced into the inlet 913 moves to the upper portion of the body portion B along one surface of the guide plate 120, and the water moved to the upper portion of the body portion B is the guide plate. It can move again to the lower part of the body part B along the other surface of 120 .

Since the water moving from the upper part of the guide plate 120 to the lower part of the body part B can evenly contact the filter body part 950 , the filtering ability of the filter body part 950 can be improved. have.

On the other hand, it is preferable that the water introduced into the inlet 913 flows toward the front surface by flowing through the rising passage 111 formed on the rear surface of the guide plate 120 .

To this end, the backflow prevention part 97 may be provided so that the water introduced into the inlet 913 flows only between the guide plate 120 and the base 910 . This is because when the water introduced into the inlet 913 flows into the place where the collecting protrusion 211 is provided, the foreign material collecting performance is reduced.

Therefore, the backflow prevention part 97 rotates to be close to the rear surface of the guide plate 120 when water flows into the body part B through the inlet 913, When the inflow is stopped, it may be provided to rotate in a direction away from the rear surface of the guide plate 120 .

The guide plate 120 is provided to be spaced apart from the lower end of the base 910 by a predetermined distance, and the backflow prevention part 97 is rotatably connected to the outer body part 94 to form the guide plate 120 . It may be provided with a length in contact with the rear surface.

When water is discharged through the inlet 913 , the backflow prevention part 97 comes into contact with the stopper 973 , and the water moves to the lower part of the body part B along the front surface of the guide plate 120 . may be discharged through the filter body 950 .

The collecting protrusions 211 may be evenly distributed on the guide plate 120 , and may be provided extending from the guide plate 120 to the filter body part 950 .

That is, the collecting part 200 may be provided only on the front surface of the guide plate 120 . This is because, when the upward flow path portion 111 is formed by the guide plate, water must be smoothly introduced into the rear surface of the guide plate 120 .

Specifically, when the guide plate 120 is provided on the inner body portion 91 , the collecting protrusion 211 extends to a length capable of contacting the outer body portion 94 or the filter body portion 950 . and can be provided.

Thereafter, the water moving to the upper part of the body part B may pass between the pair of flow path ribs 112 to move to the lower part of the body part B.

At this time, as the flow path rib 112 and the flange 911 are provided closer together, the width of the rising flow path part 111 becomes narrower. Through this arrangement relationship, it is possible to improve the flow rate and pressure of the water flowing through the rising flow path part 111, and it is possible to smoothly flow the water up to the upper part of the body part B.

The flow path rib 112 may include an inclined portion 112a for guiding the water introduced from the inlet 913 between the flange 911 and the flow path rib 112 . The inclined portion 112a may be formed at a lower portion of the flow path rib 112 , and may be inclined to be closer to the flange 911 as it rises from the inlet 913 to the upper portion of the body B.

The lower portion of the collecting plate 210 may be provided to be narrower toward the end according to the shape of the inclined portion 112a of the flow path rib 112 .

Meanwhile, the base 910 includes a coupling protrusion 910a capable of detachably fixing the collecting plate 210, and the collecting plate 210 is detachably coupled to the coupling protrusion 910a. A fixing hole 210a provided through the collecting plate 210 may be further included.

When the collecting plate 210 vibrates separately from the base 910 , foreign substances collected by the collecting plate 210 may be separated. To prevent this, the coupling protrusion 910a may be press-fitted into the fixing hole 210a. In addition, the coupling protrusion 910a may include a fixing head 910b having a larger diameter than the fixing hole 210a at the free end.

Accordingly, the collecting plate 210 can be prevented from being separated from the base 910 even when the drum 5 vibrates, and from vibrating separately from the base 910 .
