The seating hole ribs 164 are formed to correspond to the lower side inlet portion 112, and a lower rib hole 152 is formed through which washing water is guided upward, and corresponds to the upper side inlet portion 124. An upper rib hole 154 is formed to guide the washing water that is formed and guided upward to the upper side inlet 124.

The back surface of the filter housing 140 is formed with a flow path 166 through which the washing water is guided upward by the flow path guide 160.

In the above embodiment, the lint filter 100 is limited to the inner wall surface of the washing tank 6 to be directly fastened. However, the lint filter 100 is not limited to the above embodiment, and the lint filter ( It is also possible to be inserted in a separate space, such as a circulation passage for forming the 100 and the wash water circulating.

Referring to the operation according to the embodiment of the present invention configured as described above, as follows.

During operation of the washing machine, when at least one of the washing tank 6 and the pulsator 9 is rotated due to the driving of the motor 8, the washing machine 6 rises on the inner wall of the ?? A stream of water can be formed.

Water pressure of the washing water flows into the housing lower surface inlet 150 by pushing the check valve installed in the housing lower surface inlet 150.

The wash water introduced into the lower surface of the housing 150 is guided upward along the flow path 166 formed by the flow path guide 160.

Some of the washing water guided upward through the flow path 166 passes through the first rib hole 152 and flows into the lower filter 110 through the lower side inlet portion 112 of the lower filter 110. do.

In addition, the rest of the washing water guided upward through the flow path 166 passes through the second rib hole 154 and the upper filter 120 through the upper side inlet portion 124 of the upper filter 120. Flows into.

When the washing tub 6 rotates at a high speed, the washing water in the washing tub 6 comes into close contact with the inner wall of the washing tub 6 by centrifugal force, and then rises above the washing tub 6. Therefore, the washing water introduced into the filter housing 140 through the lower surface of the housing 150 may easily flow upward along the flow path 166.

In addition, the wash water in the lower filter 110 may be moved upwardly toward the upper filter 120 through the communication unit.

The wash water introduced into the lower filter 110 and the upper filter 120 is filtered inside each of the washing tanks 6 through the lower front discharge part 114 and the filter cover discharge hole 136. Can be discharged.

The lint filter of the laundry treatment machine according to the present invention includes a filter body and a filter housing, and after washing water flows in through the lower surface of the filter housing, the lint filter is guided upward in the filter housing and introduced into the side of the filter body and filtered. After that, it is configured to be discharged to the front surface. Since the washing water in the washing tank flows into the lower surface of the filter housing, the washing water can be smoothly introduced. In addition, since the wash water introduced into the filter housing flows into the side of the filter body, a larger amount of wash water can flow into the side of the filter body quickly, so that the filtering performance can be improved.
